+Contents of the @PVER@-dbg package
+-------------------------------------
+
+For debugging python and extension modules, you may want to add the contents
+of /usr/share/doc/@PVER@/gdbinit (found in the @PVER@-dev package) to your
+~/.gdbinit file.
+
+@PVER@-dbg contains two sets of packages:
+
+ - debugging symbols for the standard @PVER@ build. When this package
+ is installed, gdb will automatically load up the debugging symbols
+ from it when debugging @PVER@ or one of the included extension
+ modules.
+
+ - a separate @PVER@-dbg binary, configured --with-pydebug, enabling the
+ additional debugging code to help debug memory management problems.
+
+For the latter, all extension modules have to be recompiled to
+correctly load with an pydebug enabled build.
+
+
+Debian and Ubuntu specific changes to the debug interpreter
+-----------------------------------------------------------
+The python2.4 and python2.5 packages in Ubuntu feisty are modified to
+first look for extension modules under a different name.
+
+ normal build: foo.so
+ debug build: foo_d.so foo.so
+
+This naming schema allows installation of the extension modules into
+the same path (The naming is directly taken from the Windows builds
+which already uses this naming scheme).
+
+See https://wiki.ubuntu.com/PyDbgBuilds for more information.
+
+
+Using the python-dbg builds
+---------------------------
+
+ * Call the python-dbg or the pythonX.Y-dbg binaries instead of the
+ python or pythonX.Y binaries.
+
+ * Properties of the debug build are described in
+ /usr/share/doc/@PVER@/SpecialBuilds.txt.gz.
+ The debug interpreter is built with Py_DEBUG defined.
+
+ * From SpecialBuilds.txt: This is what is generally meant by "a debug
+ build" of Python. Py_DEBUG implies LLTRACE, Py_REF_DEBUG,
+ Py_TRACE_REFS, and PYMALLOC_DEBUG (if WITH_PYMALLOC is enabled).
+ In addition, C assert()s are enabled (via the C way: by not defining
+ NDEBUG), and some routines do additional sanity checks inside
+ "#ifdef Py_DEBUG" blocks.

+ built-in functions and modules are described in the *Python
+ Library Reference*. For an informal introduction to the language,
+ see the *Python Tutorial*. For C or C++ programmers, two
+ additional manuals exist: *Extending and Embedding the Python

+Contents of the @PVER@-minimal package
+-----------------------------------------
+
+@PVER@-minimal consists of a minimum set of modules which may be needed
+for python scripts used during the boot process. If other packages
+are needed in these scripts, don't work around the missing module, but
+file a bug report against this package. The modules in this package
+are:
+
+ __builtin__ builtin
+ __future__ module
+ _bisect extension
+ _bytesio builtin
+ _codecs builtin
+ _collections extension
+ _compat_pickle module
+ _datetime extension
+ _elementtree extension
+ _fileio builtin
+ _functools extension
+ _hashlib extensionx
+ _heapq extension
+ _imp builtin
+ _io builtin
+ _locale extension
+ _md5 extension
+ _pickle extension
+ _posixsubprocess extension
+ _random extension
+ _sha1 extension
+ _sha256 extension
+ _sha512 extension
+ _socket extension
+ _sre builtin
+ _ssl extensionx
+ _stringio extension
+ _struct extension
+ _string builtin
+ _stringio builtin
+ _symtable builtin
+ _sysconfigdata module
+ _thread builtin
+ _types builtin
+ _weakref builtin
+ _weakrefset module
+ _warnings builtin
+ configparser module
+ abc module
+ argparse module
+ array extension
+ atexit extension
+ base64 module
+ binascii extension
+ bisect module
+ builtins builtin
+ codecs module
+ collections package
+ compileall module
+ copy module
+ copyreg module
+ dis module
+ errno builtin
+ exceptions builtin
+ fcntl extension
+ fnmatch module
+ functools module
+ gc builtin
+ genericpath module
+ getopt module
+ glob module
+ grp extension
+ hashlib module
+ heapq module
+ imp module
+ importlib package
+ inspect module
+ io module
+ itertools extension
+ keyword module
+ linecache module
+ locale module
+ logging package
+ marshal builtin
+ math extension
+ opcode module
+ operator extension
+ optparse module
+ os module
+ pickle module
+ pkgutil module
+ platform module
+ posix builtin
+ posixpath module
+ pwd builtin
+ pyexpat extension
+ py_compile module
+ random module
+ re module
+ reprlib module
+ runpy module
+ select extension
+ signal builtin
+ socket module
+ spwd extension
+ sre_compile module
+ sre_constants module
+ sre_parse module
+ ssl module
+ stat module
+ string module
+ struct module
+ subprocess module
+ sys builtin
+ sysconfig module
+ syslog extension
+ tempfile module
+ textwrap module
+ time extension
+ token module
+ tokenize module
+ traceback module
+ types module
+ unicodedata extension
+ warnings module
+ weakref module
+ zipimport extension
+ zlib extension
+
+Included are as well the codecs and stringprep modules, and the encodings
+modules for all encodings except the multibyte encodings and the bz2 codec.
+
+The following modules are excluded, their import is guarded from the
+importing module:
+
+ Used in Excluded
+ ------------ ------------------------------------
+ io _dummy_thread
+ os nt ntpath os2 os2emxpath mac macpath
+ riscos riscospath riscosenviron
+ optparse gettext
+ pickle doctest
+ subprocess threading
+
+This list was derived by looking at the modules in the perl-base package,
+then adding python specific "core modules".
+
+TODO's
+------
+
+- time.strptime cannot be used. The required _strptime module is not
+ included in the -minimal package yet. _strptime, locale, _locale and
+ calendar have to be added.
+
+- modules used very often in the testsuite: copy, cPickle, operator.

+ It is incredibly hard and inconvenient to sensibly handle this in

+ - Add two test cases.
+ - Change the interpreter to build and install python extensions
+ built with the python-dbg interpreter with a different name into

+ of the interpreter tries to first load a foo_d.so or foomodule_d.so

+ package, don't exit.

+
+Hints for maintainers of Debian packages of Python extensions
+-------------------------------------------------------------
+
+Most of the content of this README can be found in the Debian Python policy.
+See /usr/share/doc/python/python-policy.txt.gz.
+
+Documentation Tools
+-------------------
+
+If your package ships documentation produced in the Python
+documentation format, you can generate it at build-time by
+build-depending on @PVER@-dev, and you will find the
+templates, tools and scripts in /usr/lib/@PVER@/doc/tools --
+adjust your build scripts accordingly.
+
+
+Makefile.pre.in issues
+----------------------
+
+Python comes with a `universal Unix Makefile for Python extensions' in
+/usr/lib/@PVER@/config/Makefile.pre.in (with Debian, this is included
+in the python-dev package), which is used by most Python extensions.
+
+In general, packages using the Makefile.pre.in approach can be packaged
+simply by running dh_make or by using one of debhelper's rules' templates
+(see /usr/doc/debhelper/examples/). Makefile.pre.in works fine with e.g.
+"make prefix=debian/tmp/usr install".
+
+One glitch: You may be running into the problem that Makefile.pre.in
+doesn't try to create all the directories when they don't exist. Therefore,
+you may have to create them manually before "make install". In most cases,
+the following should work:
+
+ ...
+ dh_installdirs /usr/lib/@PVER@
+ $(MAKE) prefix=debian/tmp/usr install
+ ...
+
+
+Byte-compilation
+----------------
+
+For speed reasons, Python internally compiles source files into a byte-code.
+To speed up subsequent imports, it tries to save the byte-code along with
+the source with an extension .pyc (resp. pyo). This will fail if the
+libraries are installed in a non-writable directory, which may be the
+case for /usr/lib/@PVER@/.
+
+Not that .pyc and .pyo files should not be relocated, since for debugging
+purposes the path of the source for is hard-coded into them.
+
+To precompile files in batches after installation, Python has a script
+compileall.py, which compiles all files in a given directory tree. The
+Debian version of compileall has been enhanced to support incremental
+compilation and to feature a ddir (destination dir) option. ddir is
+used to compile files in debian/usr/lib/python/ when they will be
+installed into /usr/lib/python/.
+
+
+Currently, there are two ways to use compileall for Debian packages. The
+first has a speed penalty, the second has a space penalty in the package.
+
+1.) Compiling and removing .pyc files in postinst/prerm:
+
+ Use dh_python(1) from the debhelper packages to add commands to byte-
+ compile on installation and to remove the byte-compiled files on removal.
+ Your package has to build-depend on: debhelper (>= 4.1.67), python.
+
+ In /usr/share/doc/@PVER@, you'll find sample.postinst and sample.prerm.
+ If you set the directory where the .py files are installed, these
+ scripts will install and remove the .pyc and .pyo files for your
+ package after unpacking resp. before removing the package.
+
+2.) Compiling the .pyc files `out of place' during installation:
+
+ As of 1.5.1, compileall.py allows you to specify a faked installation
+ directory using the "-d destdir" option, so that you can precompile
+ the files in their temporary directory
+ (e.g. debian/tmp/usr/lib/python2.1/site-packages/PACKAGE).

+
+ Python and dbm modules on Debian
+ --------------------------------
+
+This file documents the configuration of the dbm modules for Debian. It
+gives hints at the preferred use of the dbm modules.
+
+
+The preferred way to access dbm databases in Python is the anydbm module.
+dbm databases behave like mappings (dictionaries).
+
+Since there exist several dbm database formats, we choose the following
+layout for Python on Debian:
+
+ * creating a new database with anydbm will create a Berkeley DB 2.X Hash
+ database file. This is the standard format used by libdb starting
+ with glibc 2.1.
+
+ * opening an existing database with anydbm will try to guess the format
+ of the file (using whichdb) and then load it using one of the bsddb,
+ bsddb1, gdbm or dbm (only if the python-gdbm package is installed)
+ or dumbdbm modules.
+
+ * The modules use the following database formats:
+
+ - bsddb: Berkeley DB 2.X Hash (as in libc6 >=2.1 or libdb2)
+ - bsddb1: Berkeley DB 1.85 Hash (as in libc6 >=2.1 or libdb2)
+ - gdbm: GNU dbm 1.x or ndbm
+ - dbm: " (nearly the same as the gdbm module for us)
+ - dumbdbm: a hand-crafted format only used in this module
+
+ That means that all usual formats should be readable with anydbm.
+
+ * If you want to create a database in a format different from DB 2.X,
+ you can still directly use the specified module.
+
+ * I.e. bsddb is the preferred module, and DB 2.X is the preferred format.
+
+ * Note that the db1hash and bsddb1 modules are Debian specific. anydbm
+ and whichdb have been modified to support DB 2.X Hash files (see
+ below for details).
+
+
+
+For experts only:
+----------------
+
+Although bsddb employs the new DB 2.X format and uses the new Sleepycat
+DB 2 library as included with glibc >= 2.1, it's still using the old
+DB 1.85 API (which is still supported by DB 2).
+
+A more recent version 1.1 of the BSD DB module (available from
+http://starship.skyport.net/robind/python/) directly uses the DB 2.X API.
+It has a richer set of features.
+
+
+On a glibc 2.1 system, bsddb is linked with -ldb, bsddb1 is linked with
+-ldb1 and gdbm as well as dbm are linked with -lgdbm.
+
+On a glibc 2.0 system (e.g. potato for m68k or slink), bsddb will be
+linked with -ldb2 while bsddb1 will be linked with -ldb (therefore
+python-base here depends on libdb2).
+
+
+db1hash and bsddb1 nearly completely identical to dbhash and bsddb. The
+only difference is that bsddb is linked with the real DB 2 library, while
+bsddb1 is linked with an library which provides compatibility with legacy
+DB 1.85 databases.

+
+ Python 2.x for Debian
+ ---------------------
+
+This is Python 2.x packaged for Debian.
+
+This document contains information specific to the Debian packages of
+Python 2.x.
+
+
+
+ [TODO: This document is not yet up-to-date with the packages.]
+
+
+
+
+
+
+Currently, it features those two main topics:
+
+ 1. Release notes for the Debian packages:
+ 2. Notes for developers using the Debian Python packages:
+
+Release notes and documentation from the upstream package are installed
+in /usr/share/doc/python/.
+
+Up-to-date information regarding Python on Debian systems is also
+available as http://www.debian.org/~flight/python/.
+
+There's a mailing list for discussion of issues related to Python on Debian
+systems: debian-python@lists.debian.org. The list is not intended for
+general Python problems, but as a forum for maintainers of Python-related
+packages and interested third parties.
+
+
+
+1. Release notes for the Debian packages:
+
+
+Results of the regression test:
+------------------------------
+
+The package does successfully run the regression tests for all included
+modules. Seven packages are skipped since they are platform-dependent and
+can't be used with Linux.
+
+
+Noteworthy changes since the 1.4 packages:
+-----------------------------------------
+
+- Threading support enabled.
+- Tkinter for Tcl/Tk 8.x.
+- New package python-zlib.
+- The dbmmodule was dropped. Use bsddb instead. gdbmmodule is provided
+ for compatibility's sake.
+- python-elisp adheres to the new emacs add-on policy; it now depends
+ on emacsen. python-elisp probably won't work correctly with emacs19.
+ Refer to /usr/doc/python-elisp/ for more information.
+- Remember that 1.5 has dropped the `ni' interface in favor of a generic
+ `packages' concept.
+- Python 1.5 regression test as additional package python-regrtest. You
+ don't need to install this package unless you don't trust the
+ maintainer ;-).
+- once again, modified upstream's compileall.py and py_compile.py.
+ Now they support compilation of optimized byte-code (.pyo) for use
+ with "python -O", removal of .pyc and .pyo files where the .py source
+ files are missing (-d) and finally the fake of a installation directory
+ when .py files have to be compiled out of place for later installation
+ in a different directory (-i destdir, used in ./debian/rules).
+- The Debian packages for python 1.4 do call
+ /usr/lib/python1.4/compileall.py in their postrm script. Therefore
+ I had to provide a link from /usr/lib/python1.5/compileall.py, otherwise
+ the old packages won't be removed completely. THIS IS A SILLY HACK!
+
+
+
+2. Notes for developers using the Debian python packages:
+
+
+Embedding python:
+----------------
+
+The files for embedding python resp. extending the python interpreter
+are included in the python-dev package. With the configuration in the
+Debian GNU/Linux packages of python 1.5, you will want to use something
+like
+
+ -I/usr/include/python1.5 (e.g. for config.h)
+ -L/usr/lib/python1.5/config -lpython1.5 (... -lpthread)
+ (also for Makefile.pre.in, Setup etc.)
+
+Makefile.pre.in automatically gets that right. Note that unlike 1.4,
+python 1.5 has only one library, libpython1.5.a.
+
+Currently, there's no shared version of libpython. Future version of
+the Debian python packages will support this.
+
+
+Python extension packages:
+-------------------------
+
+According to www.python.org/doc/essays/packages.html, extension packages
+should only install into /usr/lib/python1.5/site-packages/ (resp.
+/usr/lib/site-python/ for packages that are definitely version independent).
+No extension package should install files directly into /usr/lib/python1.5/.
+
+But according to the FSSTND, only Debian packages are allowed to use
+/usr/lib/python1.5/. Therefore Debian Python additionally by default
+searches a second hierarchy in /usr/local/lib/. These directories take
+precedence over their equivalents in /usr/lib/.
+
+a) Locally installed Python add-ons
+
+ /usr/local/lib/python1.5/site-packages/
+ /usr/local/lib/site-python/ (version-independent modules)
+
+b) Python add-ons packaged for Debian
+
+ /usr/lib/python1.5/site-packages/
+ /usr/lib/site-python/ (version-independent modules)
+
+Note that no package must install files directly into /usr/lib/python1.5/
+or /usr/local/lib/python1.5/. Only the site-packages directory is allowed
+for third-party extensions.
+
+Use of the new `package' scheme is strongly encouraged. The `ni' interface
+is obsolete in python 1.5.
+
+Header files for extensions go into /usr/include/python1.5/.
+
+
+Installing extensions for local use only:
+----------------------------------------
+
+Most extensions use Python's Makefile.pre.in. Note that Makefile.pre.in
+by default will install files into /usr/lib/, not into /usr/local/lib/,
+which is not allowed for local extensions. You'll have to change the
+Makefile accordingly. Most times, "make prefix=/usr/local install" will
+work.
+
+
+Packaging python extensions for Debian:
+--------------------------------------
+
+Maintainers of Python extension packages should read README.maintainers.

+
+A. HISTORY OF THE SOFTWARE
+==========================
+
+Python was created in the early 1990s by Guido van Rossum at Stichting
+Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
+as a successor of a language called ABC. Guido remains Python's
+principal author, although it includes many contributions from others.
+
+In 1995, Guido continued his work on Python at the Corporation for
+National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
+in Reston, Virginia where he released several versions of the
+software.
+
+In May 2000, Guido and the Python core development team moved to
+BeOpen.com to form the BeOpen PythonLabs team. In October of the same
+year, the PythonLabs team moved to Digital Creations (now Zope
+Corporation, see http://www.zope.com). In 2001, the Python Software
+Foundation (PSF, see http://www.python.org/psf/) was formed, a
+non-profit organization created specifically to own Python-related
+Intellectual Property. Zope Corporation is a sponsoring member of
+the PSF.
+
+All Python releases are Open Source (see http://www.opensource.org for
+the Open Source Definition). Historically, most, but not all, Python
+releases have also been GPL-compatible; the table below summarizes
+the various releases.

+Footnotes:
+
+(1) GPL-compatible doesn't mean that we're distributing Python under
+ the GPL. All Python licenses, unlike the GPL, let you distribute
+ a modified version without making your changes open source. The
+ GPL-compatible licenses make it possible to combine Python with
+ other software that is released under the GPL; the others don't.
+
+(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
+ because its license has a choice of law clause. According to
+ CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
+ is "not incompatible" with the GPL.
+
+Thanks to the many outside volunteers who have worked under Guido's
+direction to make these releases possible.

+Licenses for Software linked to
+===============================
+
+Note that the choice of GPL compatibility outlined above doesn't extend
+to modules linked to particular libraries, since they change the
+effective License of the module binary.
+
+
+GNU Readline
+------------
+
+The 'readline' module makes use of GNU Readline.
+
+ The GNU Readline Library is free software; you can redistribute it
+ and/or modify it under the terms of the GNU General Public License as
+ published by the Free Software Foundation; either version 2, or (at
+ your option) any later version.
+
+ On Debian systems, you can find the complete statement in
+ /usr/share/doc/readline-common/copyright'. A copy of the GNU General
+ Public License is available in /usr/share/common-licenses/GPL-2'.
+
+
+OpenSSL
+-------
+
+The '_ssl' module makes use of OpenSSL.
+
+ The OpenSSL toolkit stays under a dual license, i.e. both the
+ conditions of the OpenSSL License and the original SSLeay license
+ apply to the toolkit. Actually both licenses are BSD-style Open
+ Source licenses. Note that both licenses are incompatible with
+ the GPL.
+
+ On Debian systems, you can find the complete license text in
+ /usr/share/doc/openssl/copyright'.

+
+ Python @VER@ for Debian
+ ---------------------
+
+This is Python @VER@ packaged for Debian.
+
+This document contains information specific to the Debian packages of
+Python @VER@.
+
+
+
+ [TODO: This document is not yet up-to-date with the packages.]
+
+Currently, it features those two main topics:
+
+ 1. Release notes for the Debian packages:
+ 2. Notes for developers using the Debian Python packages:
+
+Release notes and documentation from the upstream package are installed
+in /usr/share/doc/@PVER@/.
+
+There's a mailing list for discussion of issues related to Python on Debian
+systems: debian-python@lists.debian.org. The list is not intended for
+general Python problems, but as a forum for maintainers of Python-related
+packages and interested third parties.
+
+
+
+1. Release notes for the Debian packages:
+
+
+Results of the regression test:
+------------------------------
+
+The package does successfully run the regression tests for all included
+modules. Seven packages are skipped since they are platform-dependent and
+can't be used with Linux.
+
+
+2. Notes for developers using the Debian python packages:
+
+See the draft of the Debian Python policy in /usr/share/doc/python.
+
+distutils can be found in the @PVER@-dev package. Development files
+like the python library or Makefiles can be found in the @PVER@-dev
+package in /usr/lib/@PVER@/config. Therefore, if you need to install
+a pure python extension, you only need @PVER@. On the other hand, to
+install a C extension, you need @PVER@-dev.
+
+a) Locally installed Python add-ons
+
+ /usr/local/lib/@PVER@/site-packages/
+ /usr/local/lib/site-python/ (version-independent modules)
+
+b) Python add-ons packaged for Debian
+
+ /usr/lib/@PVER@/site-packages/
+ /usr/lib/site-python/ (version-independent modules)
+
+Note that no package must install files directly into /usr/lib/@PVER@/
+or /usr/local/lib/@PVER@/. Only the site-packages directory is allowed
+for third-party extensions.
+
+Use of the new `package' scheme is strongly encouraged. The `ni' interface
+is obsolete in python 1.5.
+
+Header files for extensions go into /usr/include/@PVER@/.
+
+
+Installing extensions for local use only:
+----------------------------------------
+
+Consider using distutils ...
+
+Most extensions use Python's Makefile.pre.in. Note that Makefile.pre.in
+by default will install files into /usr/lib/, not into /usr/local/lib/,
+which is not allowed for local extensions. You'll have to change the
+Makefile accordingly. Most times, "make prefix=/usr/local install" will
+work.
+
+
+Packaging python extensions for Debian:
+--------------------------------------
+
+Maintainers of Python extension packages should read
+
+ /usr/share/doc/python/python-policy.txt.gz

+Document: @PVER@-lib
+Title: Python Library Reference (v@VER@)
+Author: Guido van Rossum
+Abstract: This library reference manual documents Python's standard library,
+ as well as many optional library modules (which may or may not be
+ available, depending on whether the underlying platform supports
+ them and on the configuration choices made at compile time). It
+ also documents the standard types of the language and its built-in
+ functions and exceptions, many of which are not or incompletely
+ documented in the Reference Manual.

+<H2><A NAME="1.1">1.1. What is Python?</A></H2>
+Python is an interpreted, interactive, object-oriented programming
+language. It incorporates modules, exceptions, dynamic typing, very
+high level dynamic data types, and classes. Python combines
+remarkable power with very clear syntax. It has interfaces to many
+system calls and libraries, as well as to various window systems, and
+is extensible in C or C++. It is also usable as an extension language
+for applications that need a programmable interface. Finally, Python
+is portable: it runs on many brands of UNIX, on the Mac, and on PCs
+under MS-DOS, Windows, Windows NT, and OS/2.
+<P>
+To find out more, the best thing to do is to start reading the
+tutorial from the documentation set (see a few questions further
+down).

+Apart from being a computer scientist, I'm also a fan of "Monty

+And I happened to be reading some scripts from the series at the

+Python versions are numbered A.B.C or A.B. A is the major version
+number -- it is only incremented for really major changes in the
+language. B is the minor version number, incremented for less
+earth-shattering changes. C is the micro-level -- it is
+incremented for each bugfix release. See PEP 6 for more information
+about bugfix releases.
+<P>
+Not all releases have bugfix releases.
+Note that in the past (ending with 1.5.2),
+micro releases have added significant changes;
+in fact the changeover from 0.9.9 to 1.0.0 was the first time
+that either A or B changed!
+<P>
+Alpha, beta and release candidate versions have an additional suffixes.
+The suffix for an alpha version is "aN" for some small number N, the
+suffix for a beta version is "bN" for some small number N, and the
+suffix for a release candidate version is "cN" for some small number N.
+<P>
+Note that (for instance) all versions labeled 2.0aN precede the
+versions labeled 2.0bN, which precede versions labeled 2.0cN, and
+<I>those</I> precede 2.0.
+<P>
+As a rule, no changes are made between release candidates and the final
+release unless there are show-stopper bugs.
+<P>
+You may also find version numbers with a "+" suffix, e.g. "2.2+".
+These are unreleased versions, built directly from the CVS trunk.

+See also the documentation for sys.version, sys.hexversion, and
+sys.version_info.

+<H2><A NAME="1.15">1.15. Why was Python created in the first place?</A></H2>
+Here's a <I>very</I> brief summary of what got me started:
+<P>
+I had extensive experience with implementing an interpreted language
+in the ABC group at CWI, and from working with this group I had
+learned a lot about language design. This is the origin of many
+Python features, including the use of indentation for statement
+grouping and the inclusion of very-high-level data types (although the
+details are all different in Python).
+<P>
+I had a number of gripes about the ABC language, but also liked many
+of its features. It was impossible to extend the ABC language (or its
+implementation) to remedy my complaints -- in fact its lack of
+extensibility was one of its biggest problems.
+I had some experience with using Modula-2+ and talked with the
+designers of Modula-3 (and read the M3 report). M3 is the origin of
+the syntax and semantics used for exceptions, and some other Python

+<P>
+I was working in the Amoeba distributed operating system group at
+CWI. We needed a better way to do system administration than by
+writing either C programs or Bourne shell scripts, since Amoeba had
+its own system call interface which wasn't easily accessible from the
+Bourne shell. My experience with error handling in Amoeba made me
+acutely aware of the importance of exceptions as a programming
+language feature.
+<P>
+It occurred to me that a scripting language with a syntax like ABC
+but with access to the Amoeba system calls would fill the need. I
+realized that it would be foolish to write an Amoeba-specific
+language, so I decided that I needed a language that was generally
+extensible.
+<P>
+During the 1989 Christmas holidays, I had a lot of time on my hand,
+so I decided to give it a try. During the next year, while still
+mostly working on it in my own time, Python was used in the Amoeba
+project with increasing success, and the feedback from colleagues made
+me add many early improvements.
+<P>
+In February 1991, after just over a year of development, I decided
+to post to USENET. The rest is in the Misc/HISTORY file.

+<H2><A NAME="1.17">1.17. What is Python good for?</A></H2>
+Python is used in many situations where a great deal of dynamism,
+ease of use, power, and flexibility are required.
+<P>
+In the area of basic text
+manipulation core Python (without any non-core extensions) is easier
+to use and is roughly as fast as just about any language, and this makes Python
+good for many system administration type tasks and for CGI programming
+and other application areas that manipulate text and strings and such.
+<P>
+When augmented with
+standard extensions (such as PIL, COM, Numeric, oracledb, kjbuckets,
+tkinter, win32api, etc.)
+or special purpose extensions (that you write, perhaps using helper tools such
+as SWIG, or using object protocols such as ILU/CORBA or COM) Python
+becomes a very convenient "glue" or "steering"
+language that helps make heterogeneous collections of unrelated
+software packages work together.
+For example by combining Numeric with oracledb you can help your
+SQL database do statistical analysis, or even Fourier transforms.
+One of the features that makes Python excel in the "glue language" role
+is Python's simple, usable, and powerful C language runtime API.
+<P>
+Many developers also use Python extensively as a graphical user
+interface development aide.

+Very stable. New, stable releases have been coming out roughly every 3 to 12 months since 1991, and this seems likely to continue.

+With the introduction of retrospective "bugfix" releases the stability of the language implementations can be, and is being, improved independently of the new features offered by more recent major or minor releases.

+<H2><A NAME="2.12">2.12. Is Python a good language in a class for beginning programmers?</A></H2>
+Yes. This long answer attempts to address any concerns you might
+have with teaching Python as a programmer's first language.
+(If you want to discuss Python's use in education, then
+you may be interested in joining the edu-sig mailinglist.
+See <A HREF="http://www.python.org/sigs/edu-sig">http://www.python.org/sigs/edu-sig</A>/ )
+<P>
+It is still common to start students with a procedural
+(subset of a) statically typed language such as Pascal, C, or
+a subset of C++ or Java. I think that students may be better
+served by learning Python as their first language. Python has
+a very simple and consistent syntax and a large standard library.
+Most importantly, using Python in a beginning programming course
+permits students to concentrate on important programming skills,
+such as problem decomposition and data type design.
+<P>
+With Python, students can be quickly introduced to basic concepts
+such as loops and procedures. They can even probably work with
+user-defined objects in their very first course. They could
+implement a tree structure as nested Python lists, for example.
+They could be introduced to objects in their first course if
+desired. For a student who has never programmed before, using
+a statically typed language seems unnatural. It presents
+additional complexity that the student must master and slows
+the pace of the course. The students are trying to learn to
+think like a computer, decompose problems, design consistent
+interfaces, and encapsulate data. While learning to use a
+statically typed language is important, it is not necessarily the
+best topic to address in the students' first programming course.
+<P>
+Many other aspects of Python make it a good first language.
+Python has a large standard library (like Java) so that
+students can be assigned programming projects very early in the
+course that <I>do</I> something. Assignments aren't restricted to the
+standard four-function calculator and check balancing programs.
+By using the standard library, students can gain the satisfaction
+of working on realistic applications as they learn the fundamentals
+of programming. Using the standard library also teaches students
+about code reuse.
+<P>
+Python's interactive interpreter also enables students to
+test language features while they're programming. They can keep
+a window with the interpreter running while they enter their
+programs' source in another window. If they can't remember the
+methods for a list, they can do something like this:
+<P>
+<PRE>
+ >>> L = []
+ >>> dir(L)
+ ['append', 'count', 'extend', 'index', 'insert', 'pop', 'remove',
+ 'reverse', 'sort']
+ >>> print L.append.__doc__
+ L.append(object) -- append object to end
+ >>> L.append(1)
+ >>> L
+ [1]
+</PRE>
+With the interpreter, documentation is never far from the
+student as he's programming.
+<P>
+There are also good IDEs for Python. Guido van Rossum's IDLE
+is a cross-platform IDE for Python that is written in Python
+using Tk. There is also a Windows specific IDE called PythonWin.
+Emacs users will be happy to know that there is a very good Python
+mode for Emacs. All of these programming environments provide
+syntax highlighting, auto-indenting, and access to the interactive
+interpreter while coding. For more information about IDEs, see XXX.
+<P>
+If your department is currently using Pascal because it was
+designed to be a teaching language, then you'll be happy to
+know that Guido van Rossum designed Python to be simple to
+teach to everyone but powerful enough to implement real world
+applications. Python makes a good language for first time
+programmers because that was one of Python's design goals.
+There are papers at <A HREF="http://www.python.org/doc/essays">http://www.python.org/doc/essays</A>/ on the Python website
+by Python's creator explaining his objectives for the language.
+One that may interest you is titled "Computer Programming for Everybody"
+<A HREF="http://www.python.org/doc/essays/cp4e.html">http://www.python.org/doc/essays/cp4e.html</A>
+<P>
+If you're seriously considering Python as a language for your
+school, Guido van Rossum may even be willing to correspond with
+you about how the language would fit in your curriculum.
+See <A HREF="http://www.python.org/doc/FAQ.html#2.2">http://www.python.org/doc/FAQ.html#2.2</A> for examples of
+Python's use in the "real world."
+<P>
+While Python, its source code, and its IDEs are freely
+available, this consideration should not rule
+out other languages. There are other free languages (Java,
+free C compilers), and many companies are willing to waive some
+or all of their fees for student programming tools if it
+guarantees that a whole graduating class will know how to
+use their tools. That is, if one of the requirements for
+the language that will be taught is that it be freely
+available, then Python qualifies, but this requirement
+does not preclude other languages.
+<P>
+While Python jobs may not be as prevalent as C/C++/Java jobs,
+teachers should not worry about teaching students critical job
+skills in their first course. The skills that win students a
+job are those they learn in their senior classes and internships.
+Their first programming courses are there to lay a solid
+foundation in programming fundamentals. The primary question
+in choosing the language for such a course should be which
+language permits the students to learn this material without
+hindering or limiting them.
+<P>
+Another argument for Python is that there are many tasks for
+which something like C++ is overkill. That's where languages
+like Python, Perl, Tcl, and Visual Basic thrive. It's critical
+for students to know something about these languages. (Every
+employer for whom I've worked used at least one such language.)
+Of the languages listed above, Python probably makes the best
+language in a programming curriculum since its syntax is simple,
+consistent, and not unlike other languages (C/C++/Java) that
+are probably in the curriculum. By starting students with
+Python, a department simultaneously lays the foundations for
+other programming courses and introduces students to the type
+of language that is often used as a "glue" language. As an
+added bonus, Python can be used to interface with Microsoft's
+COM components (thanks to Mark Hammond). There is also Jython,
+a Java implementation of the Python interpreter, that can be
+used to connect Java components.
+<P>
+If you currently start students with Pascal or C/C++ or Java,
+you may be worried they will have trouble learning a statically
+typed language after starting with Python. I think that this
+fear most often stems from the fact that the teacher started
+with a statically typed language, and we tend to like to teach
+others in the same way we were taught. In reality, the
+transition from Python to one of these other languages is
+quite simple.
+<P>
+To motivate a statically typed language such as C++, begin the
+course by explaining that unlike Python, their first language,
+C++ is compiled to a machine dependent executable. Explain
+that the point is to make a very fast executable. To permit
+the compiler to make optimizations, programmers must help it
+by specifying the "types" of variables. By restricting each
+variable to a specific type, the compiler can reduce the
+book-keeping it has to do to permit dynamic types. The compiler
+also has to resolve references at compile time. Thus, the
+language gains speed by sacrificing some of Python's dynamic
+features. Then again, the C++ compiler provides type safety
+and catches many bugs at compile time instead of run time (a
+critical consideration for many commercial applications). C++
+is also designed for very large programs where one may want to
+guarantee that others don't touch an object's implementation.
+C++ provides very strong language features to separate an object's
+implementation from its interface. Explain why this separation
+is a good thing.
+<P>
+The first day of a C++ course could then be a whirlwind introduction
+to what C++ requires and provides. The point here is that after
+a semester or two of Python, students are hopefully competent
+programmers. They know how to handle loops and write procedures.
+They've also worked with objects, thought about the benefits of
+consistent interfaces, and used the technique of subclassing to
+specialize behavior. Thus, a whirlwind introduction to C++ could
+show them how objects and subclassing looks in C++. The
+potentially difficult concepts of object-oriented design were
+taught without the additional obstacles presented by a language
+such as C++ or Java. When learning one of these languages,
+the students would already understand the "road map." They
+understand objects; they would just be learning how objects
+fit in a statically typed languages. Language requirements
+and compiler errors that seem unnatural to beginning programmers
+make sense in this new context. Many students will find it
+helpful to be able to write a fast prototype of their algorithms
+in Python. Thus, they can test and debug their ideas before
+they attempt to write the code in the new language, saving the
+effort of working with C++ types for when they've discovered a
+working solution for their assignments. When they get annoyed
+with the rigidity of types, they'll be happy to learn about
+containers and templates to regain some of the lost flexibility
+Python afforded them. Students may also gain an appreciation
+for the fact that no language is best for every task. They'll
+see that C++ is faster, but they'll know that they can gain
+flexibility and development speed with a Python when execution
+speed isn't critical.
+<P>
+If you have any concerns that weren't addressed here, try
+posting to the Python newsgroup. Others there have done some
+work with using Python as an instructional tool. Good luck.
+We'd love to hear about it if you choose Python for your course.

+<H2><A NAME="3.1">3.1. Is there a test set?</A></H2>
+Sure. You can run it after building with "make test", or you can
+run it manually with this command at the Python prompt:
+<P>
+<PRE>
+ import test.autotest
+</PRE>
+In Python 1.4 or earlier, use
+<P>
+<PRE>
+ import autotest
+</PRE>
+The test set doesn't test <I>all</I> features of Python,
+but it goes a long way to confirm that Python is actually working.
+<P>
+NOTE: if "make test" fails, don't just mail the output to the
+newsgroup -- this doesn't give enough information to debug the
+problem. Instead, find out which test fails, and run that test
+manually from an interactive interpreter. For example, if
+"make test" reports that test_spam fails, try this interactively:
+<P>
+<PRE>
+ import test.test_spam
+</PRE>
+This generally produces more verbose output which can be diagnosed
+to debug the problem. If you find a bug in Python or the libraries, or in the tests, please report this in the Python bug tracker at SourceForge:

+You can use the GNU readline library to improve the interactive user
+interface: this gives you line editing and command history when
+calling python interactively. Its sources are distributed with
+Python (at least for 2.0). Uncomment the line
+<P>
+#readline readline.c -lreadline -ltermcap
+<P>
+in Modules/Setup. The configuration option --with-readline
+is no longer supported, at least in Python 2.0. Some hints on
+building and using the readline library:
+On SGI IRIX 5, you may have to add the following
+to rldefs.h:
+<P>
+<PRE>
+ #ifndef sigmask
+ #define sigmask(sig) (1L << ((sig)-1))
+ #endif
+</PRE>
+On some systems, you will have to add #include "rldefs.h" to the
+top of several source files, and if you use the VPATH feature, you
+will have to add dependencies of the form foo.o: foo.c to the
+Makefile for several values of foo.
+The readline library requires use of the termcap library. A
+known problem with this is that it contains entry points which
+cause conflicts with the STDWIN and SGI GL libraries. The STDWIN
+conflict can be solved by adding a line saying '#define werase w_erase' to the
+stdwin.h file (in the STDWIN distribution, subdirectory H). The
+GL conflict has been solved in the Python configure script by a
+hack that forces use of the static version of the termcap library.
+Check the newsgroup gnu.bash.bug news:gnu.bash.bug for
+specific problems with the readline library (I don't read this group
+but I've been told that it is the place for readline bugs).

+<H2><A NAME="3.29">3.29. Is there a way to get the interactive mode of the python interpreter to perform function/variable name completion?</A></H2>
+(From a posting by Guido van Rossum)
+<P>
+On Unix, if you have enabled the readline module (i.e. if Emacs-style
+command line editing and bash-style history works for you), you can
+add this by importing the undocumented standard library module
+"rlcompleter". When completing a simple identifier, it
+completes keywords, built-ins and globals in __main__; when completing
+NAME.NAME..., it evaluates (!) the expression up to the last dot and
+completes its attributes.
+<P>
+This way, you can do "import string", type "string.", hit the
+completion key twice, and see the list of names defined by the
+string module.
+<P>
+Tip: to use the tab key as the completion key, call
+<P>
+<PRE>
+ readline.parse_and_bind("tab: complete")
+</PRE>
+You can put this in a ~/.pythonrc file, and set the PYTHONSTARTUP
+environment variable to ~/.pythonrc. This will cause the completion to be enabled
+whenever you run Python interactively.
+<P>
+Notes (see the docstring for rlcompleter.py for more information):
+<P>
+* The evaluation of the NAME.NAME... form may cause arbitrary
+application defined code to be executed if an object with a
+__getattr__ hook is found. Since it is the responsibility of the
+application (or the user) to enable this feature, I consider this an
+acceptable risk. More complicated expressions (e.g. function calls or
+indexing operations) are <I>not</I> evaluated.
+<P>
+* GNU readline is also used by the built-in functions input() and
+raw_input(), and thus these also benefit/suffer from the complete
+features. Clearly an interactive application can benefit by
+specifying its own completer function and using raw_input() for all
+its input.
+<P>
+* When stdin is not a tty device, GNU readline is never
+used, and this module (and the readline module) are silently inactive.

+<H2><A NAME="3.30">3.30. Why is the Python interpreter not built as a shared library?</A></H2>
+(This is a Unix question; on Mac and Windows, it <I>is</I> a shared
+library.)
+<P>
+It's just a nightmare to get this to work on all different platforms.
+Shared library portability is a pain. And yes, I know about GNU libtool
+-- but it requires me to use its conventions for filenames etc, and it
+would require a complete and utter rewrite of all the makefile and
+config tools I'm currently using.
+<P>
+In practice, few applications embed Python -- it's much more common to
+have Python extensions, which already are shared libraries. Also,
+serious embedders often want total control over which Python version
+and configuration they use so they wouldn't want to use a standard
+shared library anyway. So while the motivation of saving space
+when lots of apps embed Python is nice in theory, I
+doubt that it will save much in practice. (Hence the low priority I
+give to making a shared library.)
+<P>
+For Linux systems, the simplest method of producing libpython1.5.so seems to
+be (originally from the Minotaur project web page,
+<A HREF="http://www.equi4.com/minotaur/minotaur.html">http://www.equi4.com/minotaur/minotaur.html</A>):
+<P>

+ (cd .extract; ar xv ../libpython1.5.a)
+ gcc -shared -o libpython1.5.so .extract/*.o
+ rm -rf .extract
+</PRE>
+In Python 2.3 this will be supported by the standard build routine
+(at least on Linux) with --enable-shared. Note however that there
+is little advantage, and it slows down Python because of the need
+for PIC code and the extra cost at startup time to find the library.

+This linker error occurs on Solaris if you attempt to build an extension module which incorporates position-dependent (non-PIC) code. A common source of problems is that a static library (.a file), such as libreadline.a or libcrypto.a is linked with the extension module. The error specifically occurs when using gcc as the compiler, but /usr/ccs/bin/ld as the linker.
+<P>
+The following solutions and work-arounds are known:
+<P>
+1. Rebuild the libraries (libreadline, libcrypto) with -fPIC (-KPIC if using the system compiler). This is recommended; all object files in a shared library should be position-independent.
+<P>
+2. Statically link the extension module and its libraries into the Python interpreter, by editing Modules/Setup.
+<P>
+3. Use GNU ld instead of /usr/ccs/bin/ld; GNU ld will accept non-PIC code in shared libraries (and mark the section writable)
+<P>
+4. Pass -mimpure-text to GCC when linking the module. This will force gcc to not pass -z text to ld; in turn, ld will make all text sections writable.
+<P>
+Options 3 and 4 are not recommended, since the ability to share code across processes is lost.

+<H2><A NAME="4.7">4.7. My program is too slow. How do I speed it up?</A></H2>
+That's a tough one, in general. There are many tricks to speed up
+Python code; I would consider rewriting parts in C only as a last
+resort. One thing to notice is that function and (especially) method
+calls are rather expensive; if you have designed a purely OO interface
+with lots of tiny functions that don't do much more than get or set an
+instance variable or call another method, you may consider using a
+more direct way, e.g. directly accessing instance variables. Also see
+the standard module "profile" (described in the Library Reference
+manual) which makes it possible to find out where
+your program is spending most of its time (if you have some patience
+-- the profiling itself can slow your program down by an order of
+magnitude).
+<P>
+Remember that many standard optimization heuristics you
+may know from other programming experience may well apply
+to Python. For example it may be faster to send output to output
+devices using larger writes rather than smaller ones in order to
+avoid the overhead of kernel system calls. Thus CGI scripts
+that write all output in "one shot" may be notably faster than
+those that write lots of small pieces of output.
+<P>
+Also, be sure to use "aggregate" operations where appropriate.
+For example the "slicing" feature allows programs to chop up
+lists and other sequence objects in a single tick of the interpreter
+mainloop using highly optimized C implementations. Thus to
+get the same effect as
+<P>
+<PRE>
+ L2 = []
+ for i in range[3]:
+ L2.append(L1[i])
+</PRE>
+it is much shorter and far faster to use
+<P>
+<PRE>
+ L2 = list(L1[:3]) # "list" is redundant if L1 is a list.
+</PRE>
+Note that the map() function, particularly used with
+builtin methods or builtin functions can be a convenient
+accelerator. For example to pair the elements of two
+lists together:
+<P>
+<PRE>
+ >>> map(None, [1,2,3], [4,5,6])
+ [(1, 4), (2, 5), (3, 6)]
+</PRE>
+or to compute a number of sines:
+<P>
+<PRE>
+ >>> map( math.sin, (1,2,3,4))
+ [0.841470984808, 0.909297426826, 0.14112000806, -0.756802495308]
+</PRE>
+The map operation completes very quickly in such cases.
+<P>
+Other examples of aggregate operations include the join and split
+methods of string objects. For example if s1..s7 are large (10K+) strings then
+"".join([s1,s2,s3,s4,s5,s6,s7]) may be far faster than
+the more obvious s1+s2+s3+s4+s5+s6+s7, since the "summation"
+will compute many subexpressions, whereas join does all
+copying in one pass. For manipulating strings also consider the
+regular expression libraries and the "substitution" operations
+String % tuple and String % dictionary. Also be sure to use
+the list.sort builtin method to do sorting, and see FAQ's 4.51
+and 4.59 for examples of moderately advanced usage -- list.sort beats
+other techniques for sorting in all but the most extreme
+circumstances.
+<P>
+There are many other aggregate operations
+available in the standard libraries and in contributed libraries
+and extensions.
+<P>
+Another common trick is to "push loops into functions or methods."
+For example suppose you have a program that runs slowly and you
+use the profiler (profile.run) to determine that a Python function ff
+is being called lots of times. If you notice that ff
+<P>
+<PRE>
+ def ff(x):
+ ...do something with x computing result...
+ return result
+</PRE>
+tends to be called in loops like (A)
+<P>
+<PRE>
+ list = map(ff, oldlist)
+</PRE>
+or (B)
+<P>
+<PRE>
+ for x in sequence:
+ value = ff(x)
+ ...do something with value...
+</PRE>
+then you can often eliminate function call overhead by rewriting
+ff to
+<P>
+<PRE>
+ def ffseq(seq):
+ resultseq = []
+ for x in seq:
+ ...do something with x computing result...
+ resultseq.append(result)
+ return resultseq
+</PRE>
+and rewrite (A) to
+<P>
+<PRE>
+ list = ffseq(oldlist)
+</PRE>
+and (B) to
+<P>
+<PRE>
+ for value in ffseq(sequence):
+ ...do something with value...
+</PRE>
+Other single calls ff(x) translate to ffseq([x])[0] with little
+penalty. Of course this technique is not always appropriate
+and there are other variants, which you can figure out.
+<P>
+You can gain some performance by explicitly storing the results of
+a function or method lookup into a local variable. A loop like
+<P>
+<PRE>
+ for key in token:
+ dict[key] = dict.get(key, 0) + 1
+</PRE>
+resolves dict.get every iteration. If the method isn't going to
+change, a faster implementation is
+<P>
+<PRE>
+ dict_get = dict.get # look up the method once
+ for key in token:
+ dict[key] = dict_get(key, 0) + 1
+</PRE>
+Default arguments can be used to determine values once, at
+compile time instead of at run time. This can only be done for
+functions or objects which will not be changed during program
+execution, such as replacing
+<P>
+<PRE>
+ def degree_sin(deg):
+ return math.sin(deg * math.pi / 180.0)
+</PRE>
+with
+<P>
+<PRE>
+ def degree_sin(deg, factor = math.pi/180.0, sin = math.sin):
+ return sin(deg * factor)
+</PRE>
+Because this trick uses default arguments for terms which should
+not be changed, it should only be used when you are not concerned
+with presenting a possibly confusing API to your users.

+This is probably an optional module (written in C!) which hasn't

+like "Tkinter", "stdwin", "gl", "Xt" or "Xm". For Tkinter, STDWIN and

+<P>
+wxWindows:
+<P>
+There's an interface to wxWindows called wxPython. wxWindows is a
+portable GUI class library written in C++. It supports GTK, Motif,
+MS-Windows and Mac as targets. Ports to other platforms are being
+contemplated or have already had some work done on them. wxWindows
+preserves the look and feel of the underlying graphics toolkit, and
+there is quite a rich widget set and collection of GDI classes.
+See the wxWindows page at <A HREF="http://www.wxwindows.org">http://www.wxwindows.org</A>/ for more details.
+wxPython is a python extension module that wraps many of the wxWindows

+<H2><A NAME="4.16">4.16. Is there an equivalent of C's "?:" ternary operator?</A></H2>
+Not directly. In many cases you can mimic a?b:c with "a and b or
+c", but there's a flaw: if b is zero (or empty, or None -- anything
+that tests false) then c will be selected instead. In many cases you
+can prove by looking at the code that this can't happen (e.g. because
+b is a constant or has a type that can never be false), but in general
+this can be a problem.
+<P>
+Tim Peters (who wishes it was Steve Majewski) suggested the following
+solution: (a and [b] or [c])[0]. Because [b] is a singleton list it
+is never false, so the wrong path is never taken; then applying [0] to
+the whole thing gets the b or c that you really wanted. Ugly, but it
+gets you there in the rare cases where it is really inconvenient to
+rewrite your code using 'if'.
+<P>
+As a last resort it is possible to implement the "?:" operator as a function:
+<P>
+<PRE>
+ def q(cond,on_true,on_false):
+ from inspect import isfunction
+</PRE>
+<PRE>
+ if cond:
+ if not isfunction(on_true): return on_true
+ else: return apply(on_true)
+ else:
+ if not isfunction(on_false): return on_false
+ else: return apply(on_false)
+</PRE>
+In most cases you'll pass b and c directly: q(a,b,c). To avoid evaluating b
+or c when they shouldn't be, encapsulate them
+within a lambda function, e.g.: q(a,lambda: b, lambda: c).
+<P>

+<P>
+It has been asked <I>why</I> Python has no if-then-else expression,

+<P>
+There are several possible answers: just as many languages do
+just fine without one; it can easily lead to less readable code;
+no sufficiently "Pythonic" syntax has been discovered; a search
+of the standard library found remarkably few places where using an
+if-then-else expression would make the code more understandable.
+<P>
+Nevertheless, in an effort to decide once and for all whether
+an if-then-else expression should be added to the language,
+PEP 308 (<A HREF="http://www.python.org/peps/pep-0308.html">http://www.python.org/peps/pep-0308.html</A>) has been

+<H2><A NAME="4.17">4.17. My class defines __del__ but it is not called when I delete the object.</A></H2>
+There are several possible reasons for this.
+<P>
+The del statement does not necessarily call __del__ -- it simply
+decrements the object's reference count, and if this reaches zero
+__del__ is called.
+<P>
+If your data structures contain circular links (e.g. a tree where
+each child has a parent pointer and each parent has a list of
+children) the reference counts will never go back to zero. You'll
+have to define an explicit close() method which removes those
+pointers. Please don't ever call __del__ directly -- __del__ should
+call close() and close() should make sure that it can be called more
+than once for the same object.
+<P>
+If the object has ever been a local variable (or argument, which is
+really the same thing) to a function that caught an expression in an
+except clause, chances are that a reference to the object still exists
+in that function's stack frame as contained in the stack trace.
+Normally, deleting (better: assigning None to) sys.exc_traceback will
+take care of this. If a stack was printed for an unhandled
+exception in an interactive interpreter, delete sys.last_traceback
+instead.
+<P>
+There is code that deletes all objects when the interpreter exits,
+but it is not called if your Python has been configured to support
+threads (because other threads may still be active). You can define
+your own cleanup function using sys.exitfunc (see question 4.4).
+<P>
+Finally, if your __del__ method raises an exception, a warning message is printed to sys.stderr.

+Starting with Python 2.0, a garbage collector periodically reclaims the space used by most cycles with no external references. (See the "gc" module documentation for details.) There <I>are</I>, however, pathological cases where it can be expected to fail. Moreover, the garbage collector runs some time after the last reference to your data structure vanishes, so your __del__ method may be called at an inconvenient and random time. This is inconvenient if you're trying to reproduce a problem. Worse, the order in which object's __del__ methods are executed is arbitrary.
+<P>
+Another way to avoid cyclical references is to use the "weakref" module, which allows you to point to objects without incrementing their reference count. Tree data structures, for instance, should use weak references for their parent and sibling pointers (if they need them!).
+<P>
+Question 6.14 is intended to explain the new garbage collection algorithm.

+A class is the particular object type created by executing

+instance objects, which embody both the data structure
+(attributes) and program routines (methods) specific to a datatype.

+A class can be based on one or more other classes, called its base

+classes is their inability to use the built-in data types

+A method is a function that you normally call as

+of classes and class instances as well as for methods of built-in
+objects. (The latter have a completely different implementation and
+only share the way their calls look in Python code.) Methods of
+classes (and class instances) are defined as functions inside the

+An unbound method is a method defined in a class that is not yet

+if you ask for an instance attribute. A bound method knows which
+instance it belongs to and calling it supplies the instance automatically;

+doesn't "magically" derive the first argument from the context -- you
+have to provide it explicitly.
+<P>
+Trivia note regarding bound methods: each reference to a bound
+method of a particular object creates a bound method object. If you

+DON'T DO THIS. REALLY. I MEAN IT. It appears that you could call
+self.__class__.__bases__[0].meth(self, arguments...) but this fails when
+a doubly-derived method is derived from your class: for its instances,
+self.__class__.__bases__[0] is your class, not its base class -- so
+(assuming you are doing this from within Derived.meth) you would start
+a recursive call.
+<P>
+Often when you want to do this you are forgetting that classes
+are first class in Python. You can "point to" the class you want
+to delegate an operation to either at the instance or at the
+subclass level. For example if you want to use a "glorp"
+operation of a superclass you can point to the right superclass
+to use.
+<P>
+<PRE>
+ class subclass(superclass1, superclass2, superclass3):

+<PRE>
+ class subsubclass(subclass):
+ delegate_glorp = superclass3
+ ...

+Note, however that setting delegate_glorp to subclass in

+Use the standard popen2 module. For example:

+ fromchild, tochild = popen2.popen2("command")
+ tochild.write("input\n")
+ tochild.flush()
+ output = fromchild.readline()
+</PRE>
+Warning: in general, it is unwise to
+do this, because you can easily cause a deadlock where your
+process is blocked waiting for output from the child, while the child
+is blocked waiting for input from you. This can be caused
+because the parent expects the child to output more text than it does,
+or it can be caused by data being stuck in stdio buffers due to lack
+of flushing. The Python parent can of course explicitly flush the data
+it sends to the child before it reads any output, but if the child is
+a naive C program it can easily have been written to never explicitly
+flush its output, even if it is interactive, since flushing is
+normally automatic.
+<P>
+Note that a deadlock is also possible if you use popen3 to read
+stdout and stderr. If one of the two is too large for the internal
+buffer (increasing the buffersize does not help) and you read()
+the other one first, there is a deadlock, too.
+<P>
+Note on a bug in popen2: unless your program calls wait()
+or waitpid(), finished child processes are never removed,
+and eventually calls to popen2 will fail because of a limit on
+the number of child processes. Calling os.waitpid with the
+os.WNOHANG option can prevent this; a good place to insert such
+a call would be before calling popen2 again.
+<P>
+Another way to produce a deadlock: Call a wait() and there is
+still more output from the program than what fits into the
+internal buffers.
+<P>
+In many cases, all you really need is to run some data through a
+command and get the result back. Unless the data is infinite in size,
+the easiest (and often the most efficient!) way to do this is to write
+it to a temporary file and run the command with that temporary file as
+input. The standard module tempfile exports a function mktemp() which
+generates unique temporary file names.

+Note that many interactive programs (e.g. vi) don't work well with

+callee, and so no call-by-reference per se. But you can simulate it
+in a number of ways:
+<P>
+1) By using global variables; but you probably shouldn't :-)
+<P>
+2) By passing a mutable (changeable in-place) object:
+<P>
+<PRE>
+ def func1(a):
+ a[0] = 'new-value' # 'a' references a mutable list
+ a[1] = a[1] + 1 # changes a shared object
+</PRE>
+<PRE>
+ args = ['old-value', 99]
+ func1(args)
+ print args[0], args[1] # output: new-value 100
+</PRE>
+3) By returning a tuple, holding the final values of arguments:
+<P>
+<PRE>
+ def func2(a, b):
+ a = 'new-value' # a and b are local names
+ b = b + 1 # assigned to new objects
+ return a, b # return new values
+</PRE>
+<PRE>
+ x, y = 'old-value', 99
+ x, y = func2(x, y)
+ print x, y # output: new-value 100
+</PRE>
+4) And other ideas that fall-out from Python's object model. For instance, it might be clearer to pass in a mutable dictionary:
+<P>
+<PRE>
+ def func3(args):
+ args['a'] = 'new-value' # args is a mutable dictionary
+ args['b'] = args['b'] + 1 # change it in-place
+</PRE>
+<PRE>
+ args = {'a':' old-value', 'b': 99}
+ func3(args)
+ print args['a'], args['b']
+</PRE>
+5) Or bundle-up values in a class instance:
+<P>
+<PRE>
+ class callByRef:
+ def __init__(self, **args):
+ for (key, value) in args.items():
+ setattr(self, key, value)
+</PRE>
+<PRE>
+ def func4(args):
+ args.a = 'new-value' # args is a mutable callByRef
+ args.b = args.b + 1 # change object in-place
+</PRE>
+<PRE>
+ args = callByRef(a='old-value', b=99)
+ func4(args)
+ print args.a, args.b
+</PRE>
+<PRE>
+ But there's probably no good reason to get this complicated :-).

+[Ken Manheimer] In Python, procedure variables are implicitly
+global, unless they are assigned anywhere within the block.
+In that case
+they are implicitly local, and you need to explicitly declare them as
+'global'.
+<P>
+Though a bit surprising at first, a moment's consideration explains
+this. On one hand, requirement of 'global' for assigned vars provides
+a bar against unintended side-effects. On the other hand, if global
+were required for all global references, you'd be using global all the
+time. Eg, you'd have to declare as global every reference to a
+builtin function, or to a component of an imported module. This
+clutter would defeat the usefulness of the 'global' declaration for
+identifying side-effects.

+Suppose you have the following modules:

+ from bar import bar_var
+ foo_var=1
+</PRE>
+bar.py:
+<P>
+<PRE>
+ from foo import foo_var
+ bar_var=2

+<PRE>
+ main imports foo
+ Empty globals for foo are created
+ foo is compiled and starts executing
+ foo imports bar
+ Empty globals for bar are created
+ bar is compiled and starts executing
+ bar imports foo (which is a no-op since there already is a module named foo)
+ bar.foo_var = foo.foo_var
+ ...
+</PRE>
+The last step fails, because Python isn't done with interpreting foo yet and the global symbol dict for foo is still empty.
+<P>
+The same thing happens when you use "import foo", and then try to access "foo.one" in global code.
+<P>
+<P>
+There are (at least) three possible workarounds for this problem.
+<P>
+Guido van Rossum recommends to avoid all uses of "from <module> import ..." (so everything from an imported module is referenced as <module>.<name>) and to place all code inside functions. Initializations of global variables and class variables should use constants or built-in functions only.
+<P>
+<P>
+Jim Roskind suggests the following order in each module:
+<P>
+<PRE>
+ exports (globals, functions, and classes that don't need imported base classes)
+ import statements
+ active code (including globals that are initialized from imported values).
+</PRE>
+Python's author doesn't like this approach much because the imports
+appear in a strange place, but has to admit that it works.
+<P>
+<P>
+<P>
+Matthias Urlichs recommends to restructure your code so that the recursive import is not necessary in the first place.
+<P>

+These solutions are not mutually exclusive.

+A more awkward way of doing things is to use pickle's little sister,

+For integers, use the built-in int() function, e.g. int('144') == 144. Similarly, long() converts from string to long integer, e.g. long('144') == 144L; and float() to floating-point, e.g. float('144') == 144.0.
+<P>
+Note that these are restricted to decimal interpretation, so
+that int('0144') == 144 and int('0x144') raises ValueError. For Python
+2.0 int takes the base to convert from as a second optional argument, so
+int('0x144', 16) == 324.
+<P>
+For greater flexibility, or before Python 1.5, import the module
+string and use the string.atoi() function for integers,
+string.atol() for long integers, or string.atof() for
+floating-point. E.g.,
+string.atoi('100', 16) == string.atoi('0x100', 0) == 256.
+See the library reference manual section for the string module for

+<P>
+While you could use the built-in function eval() instead of
+any of those, this is not recommended, because someone could pass you
+a Python expression that might have unwanted side effects (like
+reformatting your disk). It also has the effect of interpreting numbers
+as Python expressions, so that e.g. eval('09') gives a syntax error

+If you are developing the classes from scratch it might be better to
+program in a more proper object-oriented style -- instead of doing a different
+thing based on class membership, why not use a method and define the
+method differently in different classes?
+<P>
+However, there are some legitimate situations
+where you need to test for class membership.
+<P>
+In Python 1.5, you can use the built-in function isinstance(obj, cls).
+<P>
+The following approaches can be used with earlier Python versions:
+<P>
+An unobvious method is to raise the object
+as an exception and to try to catch the exception with the class you're
+testing for:
+<P>
+<PRE>
+ def is_instance_of(the_instance, the_class):
+ try:
+ raise the_instance
+ except the_class:
+ return 1
+ except:
+ return 0
+</PRE>
+This technique can be used to distinguish "subclassness"
+from a collection of classes as well
+<P>
+<PRE>
+ try:
+ raise the_instance
+ except Audible:
+ the_instance.play(largo)
+ except Visual:
+ the_instance.display(gaudy)
+ except Olfactory:
+ sniff(the_instance)
+ except:
+ raise ValueError, "dunno what to do with this!"
+</PRE>
+This uses the fact that exception catching tests for class or subclass
+membership.
+<P>
+A different approach is to test for the presence of a class attribute that
+is presumably unique for the given class. For instance:
+<P>
+<PRE>
+ class MyClass:
+ ThisIsMyClass = 1
+ ...
+</PRE>
+<PRE>
+ def is_a_MyClass(the_instance):
+ return hasattr(the_instance, 'ThisIsMyClass')
+</PRE>
+This version is easier to inline, and probably faster (inlined it
+is definitely faster). The disadvantage is that someone else could cheat:
+<P>
+<PRE>
+ class IntruderClass:
+ ThisIsMyClass = 1 # Masquerade as MyClass
+ ...
+</PRE>
+but this may be seen as a feature (anyway, there are plenty of other ways
+to cheat in Python). Another disadvantage is that the class must be
+prepared for the membership test. If you do not "control the
+source code" for the class it may not be advisable to modify the
+class to support testability.

+Delegation refers to an object oriented technique Python programmers
+may implement with particular ease. Consider the following:
+<P>
+<PRE>
+ from string import upper
+</PRE>
+<PRE>
+ class UpperOut:
+ def __init__(self, outfile):
+ self.__outfile = outfile
+ def write(self, str):
+ self.__outfile.write( upper(str) )
+ def __getattr__(self, name):
+ return getattr(self.__outfile, name)
+</PRE>
+Here the UpperOut class redefines the write method
+to convert the argument string to upper case before
+calling the underlying self.__outfile.write method, but
+all other methods are delegated to the underlying
+self.__outfile object. The delegation is accomplished
+via the "magic" __getattr__ method. Please see the
+language reference for more information on the use
+of this method.
+<P>
+Note that for more general cases delegation can
+get trickier. Particularly when attributes must be set
+as well as gotten the class must define a __settattr__
+method too, and it must do so carefully.
+<P>
+The basic implementation of __setattr__ is roughly
+equivalent to the following:
+<P>
+<PRE>
+ class X:
+ ...
+ def __setattr__(self, name, value):

+We presume for the purposes of this question you are interested

+is the PyUnit module, maintained at
+<P>
+<PRE>
+ <A HREF="http://pyunit.sourceforge.net">http://pyunit.sourceforge.net</A>/
+</PRE>
+For standalone testing, it helps to write the program so that
+it may be easily tested by using good modular design.
+In particular your program
+should have almost all functionality encapsulated in either functions
+or class methods -- and this sometimes has the surprising and
+delightful effect of making the program run faster (because
+local variable accesses are faster than global accesses).
+Furthermore the program should avoid depending on mutating
+global variables, since this makes testing much more difficult to do.
+<P>
+The "global main logic" of your program may be as simple
+as
+<P>
+<PRE>
+ if __name__=="__main__":
+ main_logic()
+</PRE>
+at the bottom of the main module of your program.
+<P>
+Once your program is organized as a tractable collection
+of functions and class behaviours you should write test
+functions that exercise the behaviours. A test suite
+can be associated with each module which automates
+a sequence of tests. This sounds like a lot of work, but
+since Python is so terse and flexible it's surprisingly easy.
+You can make coding much more pleasant and fun by
+writing your test functions in parallel with the "production
+code", since this makes it easy to find bugs and even
+design flaws earlier.

+module of a program may include a "test script interpretation"
+which invokes a self test of the module.

+</PRE>
+<PRE>
+ def stripit(pair):
+ return pair[1]
+</PRE>
+This technique, attributed to Randal Schwartz, sorts the elements
+of a list by a metric which maps each element to its "sort value".
+For example, if L is a list of string then
+<P>
+<PRE>
+ import string
+ Usorted = st(L, string.upper)
+</PRE>
+<PRE>
+ def intfield(s):
+ return string.atoi( string.strip(s[10:15] ) )
+</PRE>
+<PRE>
+ Isorted = st(L, intfield)
+</PRE>
+Usorted gives the elements of L sorted as if they were upper
+case, and Isorted gives the elements of L sorted by the integer
+values that appear in the string slices starting at position 10
+and ending at position 15. In Python 2.0 this can be done more
+naturally with list comprehensions:
+<P>
+<PRE>
+ tmp1 = [ (x.upper(), x) for x in L ] # Schwartzian transform
+ tmp1.sort()
+ Usorted = [ x[1] for x in tmp1 ]
+</PRE>
+<PRE>
+ tmp2 = [ (int(s[10:15]), s) for s in L ] # Schwartzian transform
+ tmp2.sort()
+ Isorted = [ x[1] for x in tmp2 ]
+</PRE>
+<P>
+Note that Isorted may also be computed by
+<P>
+<PRE>
+ def Icmp(s1, s2):
+ return cmp( intfield(s1), intfield(s2) )
+</PRE>
+<PRE>
+ Isorted = L[:]
+ Isorted.sort(Icmp)
+</PRE>
+but since this method computes intfield many times for each
+element of L, it is slower than the Schwartzian Transform.

+The function tuple(seq) converts any sequence into a tuple with
+the same items in the same order.
+For example, tuple([1, 2, 3]) yields (1, 2, 3) and tuple('abc')
+yields ('a', 'b', 'c'). If the argument is
+a tuple, it does not make a copy but returns the same object, so
+it is cheap to call tuple() when you aren't sure that an object
+is already a tuple.
+<P>
+The function list(seq) converts any sequence into a list with
+the same items in the same order.
+For example, list((1, 2, 3)) yields [1, 2, 3] and list('abc')
+yields ['a', 'b', 'c']. If the argument is a list,
+it makes a copy just like seq[:] would.

+You can program the class's constructor to keep track of all

+Python sequences are indexed with positive numbers and

+1 is the second index and so forth. For negative indices -1
+is the last index and -2 is the pentultimate (next to last) index
+and so forth. Think of seq[-n] as the same as seq[len(seq)-n].

+Using negative indices can be very convenient. For example

+<P>
+Sadly the list builtin method L.insert does not observe negative

+ ...
+ >>> result
+ ['else', 'sort', 'to', 'something']
+</PRE>
+And if you didn't understand the question, please see the
+example above ;c). Note that "I'm" sorts before "by" because
+uppercase "I" comes before lowercase "b" in the ascii order.
+Also see 4.51.
+<P>
+In Python 2.0 this can be done like:
+<P>
+<PRE>
+ >>> list1 = ["what", "I'm", "sorting", "by"]

+<P>
+Someone asked, why not this for the last steps:
+<P>
+<PRE>
+ result = []
+ for p in pairs: result.append(p[1])
+</PRE>
+This is much more legible. However, a quick test shows that
+it is almost twice as slow for long lists. Why? First of all,
+the append() operation has to reallocate memory, and while it
+uses some tricks to avoid doing that each time, it still has
+to do it occasionally, and apparently that costs quite a bit.
+Second, the expression "result.append" requires an extra
+attribute lookup. The attribute lookup could be done away
+with by rewriting as follows:
+<P>
+<PRE>
+ result = []
+ append = result.append
+ for p in pairs: append(p[1])
+</PRE>
+which gains back some speed, but is still considerably slower
+than the original solution, and hardly less convoluted.

+You need to do two things: the script file's mode must be executable

+as the very first line of your file - or whatever the pathname is
+where the python interpreter is installed on your platform.
+<P>
+If you would like the script to be independent of where the python

+Note -- *don't* do this for CGI scripts. The $PATH variable for

+ #! /bin/sh

+The select module is widely known to help with asynchronous
+I/O on sockets once they are connected. However, it is less
+than common knowledge how to avoid blocking on the initial
+connect() call. Jeremy Hylton has the following advice (slightly
+edited):
+<P>
+To prevent the TCP connect from blocking, you can set the socket to
+non-blocking mode. Then when you do the connect(), you will either
+connect immediately (unlikely) or get an exception that contains the
+errno. errno.EINPROGRESS indicates that the connection is in
+progress, but hasn't finished yet. Different OSes will return
+different errnos, so you're going to have to check. I can tell you
+that different versions of Solaris return different errno values.
+<P>
+In Python 1.5 and later, you can use connect_ex() to avoid
+creating an exception. It will just return the errno value.
+<P>
+To poll, you can call connect_ex() again later -- 0 or errno.EISCONN
+indicate that you're connected -- or you can pass this socket to
+select (checking to see if it is writeable).

+<P>
+There are several solutions; some involve using curses, which is a

+For complex data formats, it's best to use
+use the struct module. It's documented in the library reference.
+It allows you to take a string read from a file containing binary
+data (usually numbers) and convert it to Python objects; and vice
+versa.
+<P>
+For example, the following code reads two 2-byte integers
+and one 4-byte integer in big-endian format from a file:
+<P>
+<PRE>
+ import struct

+<PRE>
+ f = open(filename, "rb") # Open in binary mode for portability
+ s = f.read(8)
+ x, y, z = struct.unpack(">hhl", s)
+</PRE>
+The '>' in the format string forces bin-endian data; the letter
+'h' reads one "short integer" (2 bytes), and 'l' reads one
+"long integer" (4 bytes) from the string.
+<P>
+For data that is more regular (e.g. a homogeneous list of ints or
+floats), you can also use the array module, also documented

+Static data (in the sense of C++ or Java) is easy; static methods (again in the sense of C++ or Java) are not supported directly.
+<P>
+STATIC DATA
+<P>
+For example,
+<P>
+<PRE>
+ class C:
+ count = 0 # number of times C.__init__ called
+</PRE>
+<PRE>
+ def __init__(self):
+ C.count = C.count + 1
+</PRE>
+<PRE>
+ def getcount(self):
+ return C.count # or return self.count
+</PRE>
+c.count also refers to C.count for any c such that isinstance(c, C) holds, unless overridden by c itself or by some class on the base-class search path from c.__class__ back to C.
+<P>
+Caution: within a method of C,
+<P>
+<PRE>
+ self.count = 42
+</PRE>
+creates a new and unrelated instance vrbl named "count" in self's own dict. So rebinding of a class-static data name needs the
+<P>
+<PRE>
+ C.count = 314
+</PRE>
+form whether inside a method or not.
+<P>
+<P>
+STATIC METHODS
+<P>
+Static methods (as opposed to static data) are unnatural in Python, because
+<P>
+<PRE>
+ C.getcount
+</PRE>
+returns an unbound method object, which can't be invoked without supplying an instance of C as the first argument.
+<P>
+The intended way to get the effect of a static method is via a module-level function:
+<P>
+<PRE>
+ def getcount():
+ return C.count
+</PRE>
+If your code is structured so as to define one class (or tightly related class hierarchy) per module, this supplies the desired encapsulation.
+<P>
+Several tortured schemes for faking static methods can be found by searching DejaNews. Most people feel such cures are worse than the disease. Perhaps the least obnoxious is due to Pekka Pessi (mailto:<A HREF="mailto:ppessi@hut.fi">ppessi@hut.fi</A>):
+<P>
+<PRE>
+ # helper class to disguise function objects
+ class _static:
+ def __init__(self, f):

+<PRE>
+ class C:
+ count = 0
+</PRE>
+<PRE>
+ def __init__(self):
+ C.count = C.count + 1
+</PRE>
+<PRE>

+ getcount = _static(getcount)

+<H2><A NAME="4.86">4.86. Basic thread wisdom</A></H2>
+Please note that there is no way to take advantage of
+multiprocessor hardware using the Python thread model. The interpreter
+uses a global interpreter lock (GIL),
+which does not allow multiple threads to be concurrently active.
+<P>
+If you write a simple test program like this:
+<P>
+<PRE>
+ import thread
+ def run(name, n):
+ for i in range(n): print name, i
+ for i in range(10):
+ thread.start_new(run, (i, 100))
+</PRE>
+none of the threads seem to run! The reason is that as soon as
+the main thread exits, all threads are killed.
+<P>
+A simple fix is to add a sleep to the end of the program,
+sufficiently long for all threads to finish:
+<P>
+<PRE>
+ import thread, time
+ def run(name, n):
+ for i in range(n): print name, i
+ for i in range(10):
+ thread.start_new(run, (i, 100))
+ time.sleep(10) # <----------------------------!
+</PRE>
+But now (on many platforms) the threads don't run in parallel,
+but appear to run sequentially, one at a time! The reason is
+that the OS thread scheduler doesn't start a new thread until
+the previous thread is blocked.
+<P>
+A simple fix is to add a tiny sleep to the start of the run
+function:
+<P>
+<PRE>
+ import thread, time
+ def run(name, n):
+ time.sleep(0.001) # <---------------------!
+ for i in range(n): print name, i
+ for i in range(10):
+ thread.start_new(run, (i, 100))
+ time.sleep(10)
+</PRE>
+Some more hints:
+<P>
+Instead of using a time.sleep() call at the end, it's
+better to use some kind of semaphore mechanism. One idea is to
+use a the Queue module to create a queue object, let each thread
+append a token to the queue when it finishes, and let the main
+thread read as many tokens from the queue as there are threads.
+<P>
+Use the threading module instead of the thread module. It's part
+of Python since version 1.5.1. It takes care of all these details,
+and has many other nice features too!

+Python file objects are a high-level layer of abstraction on top of C streams, which in turn are a medium-level layer of abstraction on top of (among other things) low-level C file descriptors.
+<P>
+For most file objects f you create in Python via the builtin "open" function, f.close() marks the Python file object as being closed from Python's point of view, and also arranges to close the underlying C stream. This happens automatically too, in f's destructor, when f becomes garbage.
+<P>
+But stdin, stdout and stderr are treated specially by Python, because of the special status also given to them by C: doing
+<P>
+<PRE>
+ sys.stdout.close() # ditto for stdin and stderr
+</PRE>
+marks the Python-level file object as being closed, but does <I>not</I> close the associated C stream (provided sys.stdout is still bound to its default value, which is the stream C also calls "stdout").
+<P>
+To close the underlying C stream for one of these three, you should first be sure that's what you really want to do (e.g., you may confuse the heck out of extension modules trying to do I/O). If it is, use os.close:

+[adapted from c.l.py responses by Gordon McMillan & GvR]
+<P>
+A global interpreter lock (GIL) is used internally to ensure that only one thread runs in the Python VM at a time. In general, Python offers to switch among threads only between bytecode instructions (how frequently it offers to switch can be set via sys.setcheckinterval). Each bytecode instruction-- and all the C implementation code reached from it --is therefore atomic.
+<P>
+In theory, this means an exact accounting requires an exact understanding of the PVM bytecode implementation. In practice, it means that operations on shared vrbls of builtin data types (ints, lists, dicts, etc) that "look atomic" really are.
+<P>
+For example, these are atomic (L, L1, L2 are lists, D, D1, D2 are dicts, x, y
+are objects, i, j are ints):
+<P>
+<PRE>
+ L.append(x)
+ L1.extend(L2)
+ x = L[i]
+ x = L.pop()
+ L1[i:j] = L2
+ L.sort()
+ x = y
+ x.field = y
+ D[x] = y
+ D1.update(D2)
+ D.keys()
+</PRE>
+These aren't:
+<P>
+<PRE>
+ i = i+1
+ L.append(L[-1])
+ L[i] = L[j]
+ D[x] = D[x] + 1
+</PRE>
+Note: operations that replace other objects may invoke those other objects' __del__ method when their reference count reaches zero, and that can affect things. This is especially true for the mass updates to dictionaries and lists. When in doubt, use a mutex!

+<H2><A NAME="4.96">4.96. Why is join() a string method when I'm really joining the elements of a (list, tuple, sequence)?</A></H2>
+Strings became much more like other standard types starting in release 1.6, when methods were added which give the same functionality that has always been available using the functions of the string module. These new methods have been widely accepted, but the one which appears to make (some) programmers feel uncomfortable is:
+<P>
+<PRE>
+ ", ".join(['1', '2', '4', '8', '16'])
+</PRE>
+which gives the result
+<P>
+<PRE>
+ "1, 2, 4, 8, 16"
+</PRE>
+There are two usual arguments against this usage.
+<P>
+The first runs along the lines of: "It looks really ugly using a method of a string literal (string constant)", to which the answer is that it might, but a string literal is just a fixed value. If the methods are to be allowed on names bound to strings there is no logical reason to make them unavailable on literals. Get over it!
+<P>
+The second objection is typically cast as: "I am really telling a sequence to join its members together with a string constant". Sadly, you aren't. For some reason there seems to be much less difficulty with having split() as a string method, since in that case it is easy to see that
+<P>
+<PRE>
+ "1, 2, 4, 8, 16".split(", ")
+</PRE>
+is an instruction to a string literal to return the substrings delimited by the given separator (or, by default, arbitrary runs of white space). In this case a Unicode string returns a list of Unicode strings, an ASCII string returns a list of ASCII strings, and everyone is happy.
+<P>
+join() is a string method because in using it you are telling the separator string to iterate over an arbitrary sequence, forming string representations of each of the elements, and inserting itself between the elements' representations. This method can be used with any argument which obeys the rules for sequence objects, inluding any new classes you might define yourself.
+<P>
+Because this is a string method it can work for Unicode strings as well as plain ASCII strings. If join() were a method of the sequence types then the sequence types would have to decide which type of string to return depending on the type of the separator.
+<P>
+If none of these arguments persuade you, then for the moment you can continue to use the join() function from the string module, which allows you to write
+<P>
+<PRE>
+ string.join(['1', '2', '4', '8', '16'], ", ")
+</PRE>
+You will just have to try and forget that the string module actually uses the syntax you are compaining about to implement the syntax you prefer!

+<H2><A NAME="4.97">4.97. How can my code discover the name of an object?</A></H2>
+Generally speaking, it can't, because objects don't really have names. The assignment statement does not store the assigned value in the name but a reference to it. Essentially, assignment creates a binding of a name to a value. The same is true of <I>def</I> and <I>class</I> statements, but in that case the value is a callable. Consider the following code:
+<P>
+<PRE>
+ class A:
+ pass
+</PRE>
+<PRE>
+ B = A
+</PRE>
+<PRE>
+ a = B()
+ b = a
+ print b
+ <__main__.A instance at 016D07CC>
+ print a
+ <__main__.A instance at 016D07CC>
+</PRE>
+<P>
+Arguably the class has a name: even though it is bound to two names and invoked through the name B the created instance is still reported as an instance of class A. However, it is impossible to say whether the instance's name is a or b, since both names are bound to the same value.
+<P>
+Generally speaking it should not be necessary for your code to "know the names" of particular values. Unless you are deliberately writing introspective programs, this is usually an indication that a change of approach might be beneficial.

+People are often very surprised by results like this:
+<P>
+<PRE>
+ >>> 1.2-1.0
+ 0.199999999999999996
+</PRE>
+And think it is a bug in Python. It's not. It's a problem caused by
+the internal representation of a floating point number. A floating point
+number is stored as a fixed number of binary digits.
+<P>
+In decimal math, there are many numbers that can't be represented
+with a fixed number of decimal digits, i.e.
+1/3 = 0.3333333333.......
+<P>
+In the binary case, 1/2 = 0.1, 1/4 = 0.01, 1/8 = 0.001, etc. There are
+a lot of numbers that can't be represented. The digits are cut off at
+some point.
+<P>
+Since Python 1.6, a floating point's repr() function prints as many
+digits are necessary to make eval(repr(f)) == f true for any float f.
+The str() function prints the more sensible number that was probably
+intended:
+<P>
+<PRE>
+ >>> 0.2
+ 0.20000000000000001
+ >>> print 0.2
+ 0.2
+</PRE>
+Again, this has nothing to do with Python, but with the way the
+underlying C platform handles floating points, and ultimately with
+the inaccuracy you'll always have when writing down numbers of fixed
+number of digit strings.
+<P>
+One of the consequences of this is that it is dangerous to compare
+the result of some computation to a float with == !
+Tiny inaccuracies may mean that == fails.
+<P>
+Instead try something like this:
+<P>
+<PRE>
+ epsilon = 0.0000000000001 # Tiny allowed error

+<H2><A NAME="4.100">4.100. What are the "best practices" for using import in a module?</A></H2>
+First, the standard modules are great. Use them! The standard Python library is large and varied. Using modules can save you time and effort and will reduce maintainenance cost of your code. (Other programs are dedicated to supporting and fixing bugs in the standard Python modules. Coworkers may also be familiar with themodules that you use, reducing the amount of time it takes them to understand your code.)
+<P>
+The rest of this answer is largely a matter of personal preference, but here's what some newsgroup posters said (thanks to all who responded)
+<P>
+In general, don't use
+<PRE>
+ from modulename import *
+</PRE>
+Doing so clutters the importer's namespace. Some avoid this idiom even with the few modules that were designed to be imported in this manner. (Modules designed in this manner include Tkinter, thread, and wxPython.)
+<P>
+Import modules at the top of a file, one module per line. Doing so makes it clear what other modules your code requires and avoids questions of whether the module name is in scope. Using one import per line makes it easy to add and delete module imports.
+<P>
+Move imports into a local scope (such as at the top of a function definition) if there are a lot of imports, and you're trying to avoid the cost (lots of initialization time) of many imports. This technique is especially helpful if many of the imports are unnecessary depending on how the program executes. You may also want to move imports into a function if the modules are only ever used in that function. Note that loading a module the first time may be expensive (because of the one time initialization of the module) but that loading a module multiple times is virtually free (a couple of dictionary lookups). Even if the module name has gone out of scope, the module is probably available in sys.modules. Thus, there isn't really anything wrong with putting no imports at the module level (if they aren't needed) and putting all of the imports at the function level.
+<P>
+It is sometimes necessary to move imports to a function or class to avoid problems with circular imports. Gordon says:
+<PRE>
+ Circular imports are fine where both modules use the "import <module>"
+ form of import. They fail when the 2nd module wants to grab a name
+ out of the first ("from module import name") and the import is at
+ the top level. That's because names in the 1st are not yet available,
+ (the first module is busy importing the 2nd).
+</PRE>
+In this case, if the 2nd module is only used in one function, then the import can easily be moved into that function. By the time the import is called, the first module will have finished initializing, and the second module can do its import.
+<P>
+It may also be necessary to move imports out of the top level of code
+if some of the modules are platform-specific. In that case, it may not even be possible to import all of the modules at the top of the file. In this case, importing the correct modules in the corresponding platform-specific code is a good option.
+<P>
+If only instances of a specific class uses a module, then it is reasonable to import the module in the class's __init__ method and then assign the module to an instance variable so that the module is always available (via that instance variable) during the life of the object. Note that to delay an import until the class is instantiated, the import must be inside a method. Putting the import inside the class but outside of any method still causes the import to occur when the module is initialized.

+<H2><A NAME="4.102">4.102. UnicodeError: ASCII [decoding,encoding] error: ordinal not in range(128)</A></H2>
+This error indicates that your Python installation can handle
+only 7-bit ASCII strings. There are a couple ways to fix or
+workaround the problem.
+<P>
+If your programs must handle data in arbitary character set encodings, the environment the application runs in will generally identify the encoding of the data it is handing you. You need to convert the input to Unicode data using that encoding. For instance, a program that handles email or web input will typically find character set encoding information in Content-Type headers. This can then be used to properly convert input data to Unicode. Assuming the string referred to by "value" is encoded as UTF-8:
+<P>
+<PRE>
+ value = unicode(value, "utf-8")
+</PRE>
+will return a Unicode object. If the data is not correctly encoded as UTF-8, the above call will raise a UnicodeError.
+<P>
+If you only want strings coverted to Unicode which have non-ASCII data, you can try converting them first assuming an ASCII encoding, and then generate Unicode objects if that fails:
+<P>
+<PRE>
+ try:
+ x = unicode(value, "ascii")
+ except UnicodeError:
+ value = unicode(value, "utf-8")
+ else:
+ # value was valid ASCII data
+ pass
+</PRE>
+<P>
+If you normally use a character set encoding other than US-ASCII and only need to handle data in that encoding, the simplest way to fix the problem may be simply to set the encoding in sitecustomize.py. The following code is just a modified version of the encoding setup code from site.py with the relevant lines uncommented.
+<P>
+<PRE>
+ # Set the string encoding used by the Unicode implementation.
+ # The default is 'ascii'
+ encoding = "ascii" # <= CHANGE THIS if you wish
+</PRE>
+<PRE>
+ # Enable to support locale aware default string encodings.
+ import locale
+ loc = locale.getdefaultlocale()
+ if loc[1]:
+ encoding = loc[1]
+ if encoding != "ascii":
+ import sys
+ sys.setdefaultencoding(encoding)
+</PRE>
+<P>
+Also note that on Windows, there is an encoding known as "mbcs", which uses an encoding specific to your current locale. In many cases, and particularly when working with COM, this may be an appropriate default encoding to use.

+<H2><A NAME="4.103">4.103. Using strings to call functions/methods</A></H2>
+There are various techniques:
+<P>
+* Use a dictionary pre-loaded with strings and functions. The primary
+advantage of this technique is that the strings do not need to match the
+names of the functions. This is also the primary technique used to
+emulate a case construct:
+<P>
+<PRE>
+ def a():
+ pass
+</PRE>
+<PRE>
+ def b():
+ pass
+</PRE>
+<PRE>
+ dispatch = {'go': a, 'stop': b} # Note lack of parens for funcs
+</PRE>
+<PRE>
+ dispatch[get_input()]() # Note trailing parens to call function
+</PRE>
+* Use the built-in function getattr():
+<P>
+<PRE>
+ import foo
+ getattr(foo, 'bar')()
+</PRE>
+Note that getattr() works on any object, including classes, class
+instances, modules, and so on.
+<P>
+This is used in several places in the standard library, like
+this:
+<P>
+<PRE>
+ class Foo:
+ def do_foo(self):
+ ...
+</PRE>
+<PRE>
+ def do_bar(self):
+ ...
+</PRE>
+<PRE>
+ f = getattr(foo_instance, 'do_' + opname)
+ f()
+</PRE>
+<P>
+* Use locals() or eval() to resolve the function name:
+<P>
+def myFunc():
+<PRE>
+ print "hello"
+</PRE>
+fname = "myFunc"
+<P>
+f = locals()[fname]
+f()
+<P>
+f = eval(fname)
+f()
+<P>
+Note: Using eval() can be dangerous. If you don't have absolute control
+over the contents of the string, all sorts of things could happen...

+A try/except block is extremely efficient. Actually executing an
+exception is expensive. In older versions of Python (prior to 2.0), it
+was common to code this idiom:
+<P>
+<PRE>
+ try:
+ value = dict[key]
+ except KeyError:
+ dict[key] = getvalue(key)
+ value = dict[key]
+</PRE>
+This idiom only made sense when you expected the dict to have the key
+95% of the time or more; other times, you coded it like this:
+<P>
+<PRE>
+ if dict.has_key(key):
+ value = dict[key]
+ else:
+ dict[key] = getvalue(key)
+ value = dict[key]
+</PRE>
+In Python 2.0 and higher, of course, you can code this as
+<P>
+<PRE>
+ value = dict.setdefault(key, getvalue(key))
+</PRE>
+However this evaluates getvalue(key) always, regardless of whether it's needed or not. So if it's slow or has a side effect you should use one of the above variants.

+The canonical way to share information across modules within a single
+program is to create a special module (often called config or cfg).
+Just import the config module in all modules of your application; the
+module then becomes available as a global name. Because there is only
+one instance of each module, any changes made to the module object get
+reflected everywhere. For example:
+<P>
+config.py:

+ config.x = 1

+You are using a version of Python that uses a 4-byte representation for
+Unicode characters, but the extension module you are importing (possibly
+indirectly) was compiled using a Python that uses a 2-byte representation
+for Unicode characters (the default).
+<P>
+If instead the name of the undefined symbol starts with PyUnicodeUCS4_,
+the problem is the same by the relationship is reversed: Python was
+built using 2-byte Unicode characters, and the extension module was
+compiled using a Python with 4-byte Unicode characters.
+<P>
+This can easily occur when using pre-built extension packages. RedHat
+Linux 7.x, in particular, provides a "python2" binary that is compiled
+with 4-byte Unicode. This only causes the link failure if the extension
+uses any of the PyUnicode_*() functions. It is also a problem if if an
+extension uses any of the Unicode-related format specifiers for
+Py_BuildValue (or similar) or parameter-specifications for
+PyArg_ParseTuple().
+<P>
+You can check the size of the Unicode character a Python interpreter is
+using by checking the value of sys.maxunicode:
+<P>
+<PRE>
+ >>> import sys
+ >>> if sys.maxunicode > 65535:
+ ... print 'UCS4 build'
+ ... else:
+ ... print 'UCS2 build'
+</PRE>
+The only way to solve this problem is to use extension modules compiled
+with a Python binary built using the same size for Unicode characters.

+QUESTION:
+<P>
+I have a module and I wish to generate a .pyc file.
+How do I do it? Everything I read says that generation of a .pyc file is
+"automatic", but I'm not getting anywhere.
+<P>
+<P>
+ANSWER:
+<P>
+When a module is imported for the first time (or when the source is more
+recent than the current compiled file) a .pyc file containing the compiled code should be created in the
+same directory as the .py file.
+<P>
+One reason that a .pyc file may not be created is permissions problems with the directory. This can happen, for example, if you develop as one user but run as another, such as if you are testing with a web server.
+<P>
+However, in most cases, that's not the problem.
+<P>
+Creation of a .pyc file is "automatic" if you are importing a module and Python has the
+ability (permissions, free space, etc...) to write the compiled module
+back to the directory. But note that running Python on a top level script is not considered an
+import and so no .pyc will be created automatically. For example, if you have a top-level module abc.py that imports another module xyz.py, when you run abc, xyz.pyc will be created since xyz is imported, but no abc.pyc file will be created since abc isn't imported.
+<P>
+If you need to create abc.pyc -- that is, to create a .pyc file for a
+module that is not imported -- you can. (Look up
+the py_compile and compileall modules in the Library Reference.)
+<P>
+You can manually compile any module using the "py_compile" module. One
+way is to use the compile() function in that module interactively:
+<P>
+<PRE>
+ >>> import py_compile
+ >>> py_compile.compile('abc.py')
+</PRE>
+This will write the .pyc to the same location as abc.py (or you
+can override that with the optional parameter cfile).
+<P>
+You can also automatically compile all files in a directory or
+directories using the "compileall" module, which can also be run
+straight from the command line.
+<P>
+You can do it from the shell (or DOS) prompt by entering:
+<PRE>
+ python compile.py abc.py
+</PRE>
+or
+<PRE>
+ python compile.py *
+</PRE>
+Or you can write a script to do it on a list of filenames that you enter.
+<P>
+<PRE>
+ import sys
+ from py_compile import compile
+</PRE>
+<PRE>
+ if len(sys.argv) <= 1:
+ sys.exit(1)
+</PRE>
+<PRE>
+ for file in sys.argv[1:]:
+ compile(file)

+The PyObject_CallMethod() function can be used to call an arbitrary

+<P>

+ PyObject *
+ PyObject_CallMethod(PyObject *object, char *method_name,

+This works for any object that has methods -- whether built-in or

+(Due to Mark Hammond):
+<P>
+In Python code, define an object that supports the "write()" method.
+Redirect sys.stdout and sys.stderr to this object.
+Call print_error, or just allow the standard traceback mechanism to
+work. Then, the output will go wherever your write() method sends it.
+<P>
+The easiest way to do this is to use the StringIO class in the standard
+library.
+<P>
+Sample code and use for catching stdout:
+<PRE>
+ >>> class StdoutCatcher:
+ ... def __init__(self):
+ ... self.data = ''
+ ... def write(self, stuff):
+ ... self.data = self.data + stuff
+ ...
+ >>> import sys
+ >>> sys.stdout = StdoutCatcher()

+ >>> print 'hello world!'

+ foo
+ hello world!

+You can get a pointer to the module object as follows:

+<PRE>
+ module = PyImport_ImportModule("<modulename>");
+</PRE>
+If the module hasn't been imported yet (i.e. it is not yet present in

+the value of sys.modules["<modulename>"]. Note that it doesn't enter
+the module into any namespace -- it only ensures it has been

+<P>
+You can then access the module's attributes (i.e. any name defined in
+the module) as follows:

+<H2><A NAME="5.15">5.15. How to tell "incomplete input" from "invalid input"?</A></H2>
+Sometimes you want to emulate the Python interactive interpreter's
+behavior, where it gives you a continuation prompt when the input
+is incomplete (e.g. you typed the start of an "if" statement
+or you didn't close your parentheses or triple string quotes),
+but it gives you a syntax error message immediately when the input
+is invalid.
+<P>
+In Python you can use the codeop module, which approximates the
+parser's behavior sufficiently. IDLE uses this, for example.
+<P>
+The easiest way to do it in C is to call PyRun_InteractiveLoop()
+(in a separate thread maybe) and let the Python interpreter handle
+the input for you. You can also set the PyOS_ReadlineFunctionPointer
+to point at your custom input function. See Modules/readline.c and
+Parser/myreadline.c for more hints.
+<P>
+However sometimes you have to run the embedded Python interpreter
+in the same thread as your rest application and you can't allow the
+PyRun_InteractiveLoop() to stop while waiting for user input.
+The one solution then is to call PyParser_ParseString()
+and test for e.error equal to E_EOF (then the input is incomplete).
+Sample code fragment, untested, inspired by code from Alex Farber:
+<P>
+<PRE>
+ #include <Python.h>
+ #include <node.h>
+ #include <errcode.h>
+ #include <grammar.h>
+ #include <parsetok.h>
+ #include <compile.h>
+</PRE>
+<PRE>
+ int testcomplete(char *code)
+ /* code should end in \n */
+ /* return -1 for error, 0 for incomplete, 1 for complete */
+ {
+ node *n;
+ perrdetail e;
+</PRE>
+<PRE>
+ n = PyParser_ParseString(code, &_PyParser_Grammar,
+ Py_file_input, &e);
+ if (n == NULL) {
+ if (e.error == E_EOF)
+ return 0;
+ return -1;
+ }
+</PRE>
+<PRE>
+ PyNode_Free(n);
+ return 1;
+ }
+</PRE>
+Another solution is trying to compile the received string with
+Py_CompileString(). If it compiles fine - try to execute the returned
+code object by calling PyEval_EvalCode(). Otherwise save the input for
+later. If the compilation fails, find out if it's an error or just
+more input is required - by extracting the message string from the
+exception tuple and comparing it to the "unexpected EOF while parsing".

+Usually you would like to be able to inherit from a Python type when

+You need to be careful when instantiating immutable types like integers or strings. See <A HREF="http://www.amk.ca/python/2.2">http://www.amk.ca/python/2.2</A>/, section 2, for details.
+<P>
+Prior to version 2.2, Python (like Java) insisted that there are first-class and second-class objects (the former are types, the latter classes), and never the twain shall meet.
+<P>
+The library has, however, done a good job of providing class wrappers for the more commonly desired objects (see UserDict, UserList and UserString for examples), and more are always welcome if you happen to be in the mood to write code. These wrappers still exist in Python 2.2.

+Basically I believe that using indentation for grouping is
+extremely elegant and contributes a lot to the clarity of the average
+Python program. Most people learn to love this feature after a while.
+Some arguments for it:
+<P>
+Since there are no begin/end brackets there cannot be a disagreement
+between grouping perceived by the parser and the human reader. I
+remember long ago seeing a C fragment like this:
+<P>
+<PRE>
+ if (x <= y)
+ x++;
+ y--;
+ z++;
+</PRE>
+and staring a long time at it wondering why y was being decremented
+even for x > y... (And I wasn't a C newbie then either.)
+<P>
+Since there are no begin/end brackets, Python is much less prone to
+coding-style conflicts. In C there are loads of different ways to
+place the braces (including the choice whether to place braces around
+single statements in certain cases, for consistency). If you're used
+to reading (and writing) code that uses one style, you will feel at
+least slightly uneasy when reading (or being required to write)
+another style.
+Many coding styles place begin/end brackets on a line by themself.
+This makes programs considerably longer and wastes valuable screen
+space, making it harder to get a good overview over a program.
+Ideally, a function should fit on one basic tty screen (say, 20
+lines). 20 lines of Python are worth a LOT more than 20 lines of C.
+This is not solely due to the lack of begin/end brackets (the lack of
+declarations also helps, and the powerful operations of course), but
+it certainly helps!

+-- fixed and unchanging storage requirements. (This is also one of
+the reasons for the distinction between tuples and lists.) The
+other is that strings in Python are considered as "elemental" as

+<H2><A NAME="6.5">6.5. Why does Python use methods for some functionality (e.g. list.index()) but functions for other (e.g. len(list))?</A></H2>
+The major reason is history. Functions were used for those
+operations that were generic for a group of types and which
+were intended to work even for objects that didn't have
+methods at all (e.g. numbers before type/class unification
+began, or tuples).
+<P>
+It is also convenient to have a function that can readily be applied
+to an amorphous collection of objects when you use the functional features of Python (map(), apply() et al).
+<P>
+In fact, implementing len(), max(), min() as a built-in function is
+actually less code than implementing them as methods for each type.
+One can quibble about individual cases but it's a part of Python,
+and it's too late to change such things fundamentally now. The
+functions have to remain to avoid massive code breakage.
+<P>
+Note that for string operations Python has moved from external functions
+(the string module) to methods. However, len() is still a function.

+<H2><A NAME="6.7">6.7. Why must 'self' be declared and used explicitly in method definitions and calls?</A></H2>
+So, is your current programming language C++ or Java? :-)
+When classes were added to Python, this was (again) the simplest way of
+implementing methods without too many changes to the interpreter. The
+idea was borrowed from Modula-3. It turns out to be very useful, for
+a variety of reasons.
+<P>
+First, it makes it more obvious that you are using a method or
+instance attribute instead of a local variable. Reading "self.x" or
+"self.meth()" makes it absolutely clear that an instance variable or
+method is used even if you don't know the class definition by heart.
+In C++, you can sort of tell by the lack of a local variable
+declaration (assuming globals are rare or easily recognizable) -- but
+in Python, there are no local variable declarations, so you'd have to
+look up the class definition to be sure.
+<P>
+Second, it means that no special syntax is necessary if you want to
+explicitly reference or call the method from a particular class. In
+C++, if you want to use a method from base class that is overridden in
+a derived class, you have to use the :: operator -- in Python you can
+write baseclass.methodname(self, <argument list>). This is
+particularly useful for __init__() methods, and in general in cases
+where a derived class method wants to extend the base class method of
+the same name and thus has to call the base class method somehow.
+<P>
+Lastly, for instance variables, it solves a syntactic problem with
+assignment: since local variables in Python are (by definition!) those
+variables to which a value assigned in a function body (and that
+aren't explicitly declared global), there has to be some way to tell
+the interpreter that an assignment was meant to assign to an instance
+variable instead of to a local variable, and it should preferably be
+syntactic (for efficiency reasons). C++ does this through
+declarations, but Python doesn't have declarations and it would be a
+pity having to introduce them just for this purpose. Using the
+explicit "self.var" solves this nicely. Similarly, for using instance
+variables, having to write "self.var" means that references to
+unqualified names inside a method don't have to search the instance's
+directories.

+Answer 1: Unfortunately, the interpreter pushes at least one C stack

+Answer 2: Fortunately, there is Stackless Python, which has a completely redesigned interpreter loop that avoids the C stack. It's still experimental but looks very promising. Although it is binary compatible with standard Python, it's still unclear whether Stackless will make it into the core -- maybe it's just too revolutionary.

+<H2><A NAME="6.12">6.12. Why is there no more efficient way of iterating over a dictionary than first constructing the list of keys()?</A></H2>
+As of Python 2.2, you can now iterate over a dictionary directly,
+using the new implied dictionary iterator:
+<P>
+<PRE>
+ for k in d: ...
+</PRE>
+There are also methods returning iterators over the values and items:
+<P>
+<PRE>
+ for k in d.iterkeys(): # same as above
+ for v in d.itervalues(): # iterate over values
+ for k, v in d.iteritems(): # iterate over items
+</PRE>
+All these require that you do not modify the dictionary during the loop.
+<P>
+For previous Python versions, the following defense should do:
+<P>
+Have you tried it? I bet it's fast enough for your purposes! In
+most cases such a list takes only a few percent of the space occupied
+by the dictionary. Apart from the fixed header,
+the list needs only 4 bytes (the size of a pointer) per
+key. A dictionary uses 12 bytes per key plus between 30 and 70
+percent hash table overhead, plus the space for the keys and values.
+By necessity, all keys are distinct objects, and a string object (the most
+common key type) costs at least 20 bytes plus the length of the
+string. Add to that the values contained in the dictionary, and you
+see that 4 bytes more per item really isn't that much more memory...
+<P>
+A call to dict.keys() makes one fast scan over the dictionary
+(internally, the iteration function does exist) copying the pointers
+to the key objects into a pre-allocated list object of the right size.
+The iteration time isn't lost (since you'll have to iterate anyway --
+unless in the majority of cases your loop terminates very prematurely
+(which I doubt since you're getting the keys in random order).
+<P>
+I don't expose the dictionary iteration operation to Python
+programmers because the dictionary shouldn't be modified during the
+entire iteration -- if it is, there's a small chance that the
+dictionary is reorganized because the hash table becomes too full, and
+then the iteration may miss some items and see others twice. Exactly
+because this only occurs rarely, it would lead to hidden bugs in
+programs: it's easy never to have it happen during test runs if you
+only insert or delete a few items per iteration -- but your users will
+surely hit upon it sooner or later.

+Not easily. Python's high level data types, dynamic typing of
+objects and run-time invocation of the interpreter (using eval() or
+exec) together mean that a "compiled" Python program would probably
+consist mostly of calls into the Python run-time system, even for
+seemingly simple operations like "x+1".
+<P>
+Several projects described in the Python newsgroup or at past
+Python conferences have shown that this approach is feasible,
+although the speedups reached so far are only modest (e.g. 2x).
+JPython uses the same strategy for compiling to Java bytecode.
+(Jim Hugunin has demonstrated that in combination with whole-program
+analysis, speedups of 1000x are feasible for small demo programs.
+See the website for the 1997 Python conference.)
+<P>
+Internally, Python source code is always translated into a "virtual
+machine code" or "byte code" representation before it is interpreted
+(by the "Python virtual machine" or "bytecode interpreter"). In order
+to avoid the overhead of parsing and translating modules that rarely
+change over and over again, this byte code is written on a file whose
+name ends in ".pyc" whenever a module is parsed (from a file whose
+name ends in ".py"). When the corresponding .py file is changed, it
+is parsed and translated again and the .pyc file is rewritten.
+<P>
+There is no performance difference once the .pyc file has been loaded
+(the bytecode read from the .pyc file is exactly the same as the bytecode
+created by direct translation). The only difference is that loading
+code from a .pyc file is faster than parsing and translating a .py
+file, so the presence of precompiled .pyc files will generally improve
+start-up time of Python scripts. If desired, the Lib/compileall.py
+module/script can be used to force creation of valid .pyc files for a
+given set of modules.
+<P>
+Note that the main script executed by Python, even if its filename
+ends in .py, is not compiled to a .pyc file. It is compiled to
+bytecode, but the bytecode is not saved to a file.
+<P>
+If you are looking for a way to translate Python programs in order to
+distribute them in binary form, without the need to distribute the
+interpreter and library as well, have a look at the freeze.py script
+in the Tools/freeze directory. This creates a single binary file
+incorporating your program, the Python interpreter, and those parts of
+the Python library that are needed by your program. Of course, the
+resulting binary will only run on the same type of platform as that
+used to create it.
+<P>
+Newsflash: there are now several programs that do this, to some extent.
+Look for Psyco, Pyrex, PyInline, Py2Cmod, and Weave.

+<H2><A NAME="6.14">6.14. How does Python manage memory?</A></H2>
+The details of Python memory management depend on the implementation.
+The standard Python implementation (the C implementation) uses reference
+counting and another mechanism to collect reference cycles.
+<P>
+Jython relies on the Java runtime; so it uses
+the JVM's garbage collector. This difference can cause some subtle
+porting problems if your Python code depends on the behavior of
+the reference counting implementation.
+<P>
+The reference cycle collector was added in CPython 2.0. It
+periodically executes a cycle detection algorithm which looks for inaccessible cycles and deletes the objects involved. A new gc module provides functions to perform a garbage collection, obtain debugging statistics, and tuning the collector's parameters.
+<P>
+The detection of cycles can be disabled when Python is compiled, if you can't afford even a tiny speed penalty or suspect that the cycle collection is buggy, by specifying the "--without-cycle-gc" switch when running the configure script.
+<P>
+Sometimes objects get stuck in "tracebacks" temporarily and hence are not deallocated when you might expect. Clear the tracebacks via
+<P>
+<PRE>
+ import sys
+ sys.exc_traceback = sys.last_traceback = None
+</PRE>
+Tracebacks are used for reporting errors and implementing debuggers and related things. They contain a portion of the program state extracted during the handling of an exception (usually the most recent exception).
+<P>
+In the absence of circularities and modulo tracebacks, Python programs need not explicitly manage memory.
+<P>
+Why python doesn't use a more traditional garbage collection
+scheme? For one thing, unless this were
+added to C as a standard feature, it's a portability pain in the ass.
+And yes, I know about the Xerox library. It has bits of assembler
+code for <I>most</I> <I>common</I> platforms. Not for all. And although it is
+mostly transparent, it isn't completely transparent (when I once
+linked Python with it, it dumped core).
+<P>
+Traditional GC also becomes a problem when Python gets embedded into
+other applications. While in a stand-alone Python it may be fine to
+replace the standard malloc() and free() with versions provided by the
+GC library, an application embedding Python may want to have its <I>own</I>
+substitute for malloc() and free(), and may not want Python's. Right
+now, Python works with anything that implements malloc() and free()
+properly.
+<P>
+In Jython, the following code (which is
+fine in C Python) will probably run out of file descriptors long before
+it runs out of memory:
+<P>
+<PRE>
+ for file in <very long list of files>:
+ f = open(file)
+ c = f.read(1)
+</PRE>
+Using the current reference counting and destructor scheme, each new
+assignment to f closes the previous file. Using GC, this is not
+guaranteed. Sure, you can think of ways to fix this. But it's not
+off-the-shelf technology. If you want to write code that will
+work with any Python implementation, you should explicitly close
+the file; this will work regardless of GC:
+<P>
+<PRE>
+ for file in <very long list of files>:
+ f = open(file)
+ c = f.read(1)
+ f.close()

+<H2><A NAME="6.18">6.18. Why must dictionary keys be immutable?</A></H2>
+The hash table implementation of dictionaries uses a hash value
+calculated from the key value to find the key. If the key were
+a mutable object, its value could change, and thus its hash could
+change. But since whoever changes the key object can't tell that
+is incorporated in a dictionary, it can't move the entry around in
+the dictionary. Then, when you try to look up the same object
+in the dictionary, it won't be found, since its hash value is different;
+and if you try to look up the old value, it won't be found either,
+since the value of the object found in that hash bin differs.
+<P>
+If you think you need to have a dictionary indexed with a list,
+try to use a tuple instead. The function tuple(l) creates a tuple
+with the same entries as the list l.
+<P>
+Some unacceptable solutions that have been proposed:
+<P>
+- Hash lists by their address (object ID). This doesn't work because
+if you construct a new list with the same value it won't be found;
+e.g.,
+<P>
+<PRE>
+ d = {[1,2]: '12'}
+ print d[[1,2]]
+</PRE>
+will raise a KeyError exception because the id of the [1,2] used
+in the second line differs from that in the first line.
+In other words, dictionary keys should be compared using '==', not using 'is'.
+<P>
+- Make a copy when using a list as a key. This doesn't work because
+the list (being a mutable object) could contain a reference to itself,
+and then the copying code would run into an infinite loop.
+<P>
+- Allow lists as keys but tell the user not to modify them. This would
+allow a class of hard-to-track bugs in programs that I'd rather not see;
+it invalidates an important invariant of dictionaries (every value in
+d.keys() is usable as a key of the dictionary).
+<P>
+- Mark lists as read-only once they are used as a dictionary key.
+The problem is that it's not just the top-level object that could change
+its value; you could use a tuple containing a list as a key. Entering
+anything as a key into a dictionary would require marking all objects
+reachable from there as read-only -- and again, self-referential objects
+could cause an infinite loop again (and again and again).
+<P>
+There is a trick to get around this if you need to, but
+use it at your own risk: You
+can wrap a mutable structure inside a class instance which
+has both a __cmp__ and a __hash__ method.
+<P>
+<PRE>
+ class listwrapper:
+ def __init__(self, the_list):
+ self.the_list = the_list
+ def __cmp__(self, other):
+ return self.the_list == other.the_list
+ def __hash__(self):
+ l = self.the_list
+ result = 98767 - len(l)*555
+ for i in range(len(l)):
+ try:
+ result = result + (hash(l[i]) % 9999999) * 1001 + i
+ except:
+ result = (result % 7777777) + i * 333
+ return result
+</PRE>
+Note that the hash computation is complicated by the
+possibility that some members of the list may be unhashable
+and also by the possibility of arithmetic overflow.
+<P>
+You must make
+sure that the hash value for all such wrapper objects that reside in a
+dictionary (or other hash based structure), remain fixed while
+the object is in the dictionary (or other structure).
+<P>
+Furthermore it must always be the case that if
+o1 == o2 (ie o1.__cmp__(o2)==0) then hash(o1)==hash(o2)
+(ie, o1.__hash__() == o2.__hash__()), regardless of whether
+the object is in a dictionary or not.
+If you fail to meet these restrictions dictionaries and other
+hash based structures may misbehave!
+<P>
+In the case of listwrapper above whenever the wrapper
+object is in a dictionary the wrapped list must not change
+to avoid anomalies. Don't do this unless you are prepared
+to think hard about the requirements and the consequences
+of not meeting them correctly. You've been warned!

+The Pythonic use of the word "type" is quite different from
+common usage in much of the rest of the programming language
+world. A "type" in Python is a description for an object's operations
+as implemented in C. All classes have the same operations
+implemented in C which sometimes "call back" to differing program
+fragments implemented in Python, and hence all classes have the
+same type. Similarly at the C level all class instances have the
+same C implementation, and hence all instances have the same
+type.
+<P>
+Remember that in Python usage "type" refers to a C implementation
+of an object. To distinguish among instances of different classes
+use Instance.__class__, and also look to 4.47. Sorry for the
+terminological confusion, but at this point in Python's development
+nothing can be done!

+Objects referenced from Python module global name spaces are
+not always deallocated when Python exits.
+<P>
+This may happen if there are circular references (see question
+4.17). There are also certain bits of memory that are allocated
+by the C library that are impossible to free (e.g. a tool
+like Purify will complain about these).
+<P>
+But in general, Python 1.5 and beyond
+(in contrast with earlier versions) is quite agressive about
+cleaning up memory on exit.
+<P>
+If you want to force Python to delete certain things on deallocation
+use the sys.exitfunc hook to force those deletions. For example
+if you are debugging an extension module using a memory analysis
+tool and you wish to make Python deallocate almost everything
+you might use an exitfunc like this one:
+<P>
+<PRE>
+ import sys
+</PRE>
+<PRE>
+ def my_exitfunc():
+ print "cleaning up"
+ import sys
+ # do order dependant deletions here
+ ...
+ # now delete everything else in arbitrary order
+ for x in sys.modules.values():
+ d = x.__dict__
+ for name in d.keys():
+ del d[name]
+</PRE>
+<PRE>
+ sys.exitfunc = my_exitfunc
+</PRE>
+Other exitfuncs can be less drastic, of course.
+<P>
+(In fact, this one just does what Python now already does itself;
+but the example of using sys.exitfunc to force cleanups is still
+useful.)

+The notation

+</PRE>
+usually translates to the equivalent of
+<P>
+<PRE>
+ Class.attribute(instance, arg1, arg2)

+where Class is a (super)class of instance. Similarly
+<P>

+sets an attribute of an instance (overriding any attribute of a class
+that instance inherits).
+<P>
+Sometimes programmers want to have
+different behaviours -- they want a method which does not bind
+to the instance and a class attribute which changes in place.
+Python does not preclude these behaviours, but you have to
+adopt a convention to implement them. One way to accomplish
+this is to use "list wrappers" and global functions.

+It is often expected that a function CALL creates new objects for default
+values. This is not what happens. Default values are created when the
+function is DEFINED, that is, there is only one such object that all
+functions refer to. If that object is changed, subsequent calls to the
+function will refer to this changed object. By definition, immutable objects
+(like numbers, strings, tuples, None) are safe from change. Changes to mutable
+objects (like dictionaries, lists, class instances) is what causes the
+confusion.
+<P>
+Because of this feature it is good programming practice not to use mutable
+objects as default values, but to introduce them in the function.
+Don't write:
+<P>
+<PRE>

+Actually, you can use exceptions to provide a "structured goto"

+<H2><A NAME="6.27">6.27. How do you make a higher order function in Python?</A></H2>
+You have two choices: you can use default arguments and override
+them or you can use "callable objects." For example suppose you
+wanted to define linear(a,b) which returns a function f where f(x)
+computes the value a*x+b. Using default arguments:
+<P>
+<PRE>
+ def linear(a,b):
+ def result(x, a=a, b=b):
+ return a*x + b
+ return result
+</PRE>
+Or using callable objects:
+<P>
+<PRE>
+ class linear:
+ def __init__(self, a, b):
+ self.a, self.b = a,b
+ def __call__(self, x):
+ return self.a * x + self.b
+</PRE>
+In both cases:
+<P>
+<PRE>
+ taxes = linear(0.3,2)
+</PRE>
+gives a callable object where taxes(10e6) == 0.3 * 10e6 + 2.
+<P>
+The defaults strategy has the disadvantage that the default arguments
+could be accidentally or maliciously overridden. The callable objects
+approach has the disadvantage that it is a bit slower and a bit
+longer. Note however that a collection of callables can share
+their signature via inheritance. EG
+<P>
+<PRE>
+ class exponential(linear):
+ # __init__ inherited
+ def __call__(self, x):
+ return self.a * (x ** self.b)
+</PRE>
+On comp.lang.python, <A HREF="mailto:zenin@bawdycaste.org">zenin@bawdycaste.org</A> points out that
+an object can encapsulate state for several methods in order
+to emulate the "closure" concept from functional programming
+languages, for example:
+<P>
+<PRE>
+ class counter:
+ value = 0
+ def set(self, x): self.value = x
+ def up(self): self.value=self.value+1
+ def down(self): self.value=self.value-1
+</PRE>
+<PRE>
+ count = counter()
+ inc, dec, reset = count.up, count.down, count.set
+</PRE>
+Here inc, dec and reset act like "functions which share the

+like that way of thinking).

+Raw strings were designed to ease creating input for processors (chiefly

+<H2><A NAME="6.30">6.30. Why can't I use an assignment in an expression?</A></H2>
+Many people used to C or Perl complain that they want to be able to
+use e.g. this C idiom:
+<P>
+<PRE>
+ while (line = readline(f)) {
+ ...do something with line...
+ }
+</PRE>
+where in Python you're forced to write this:
+<P>
+<PRE>
+ while 1:
+ line = f.readline()
+ if not line:
+ break
+ ...do something with line...
+</PRE>
+This issue comes up in the Python newsgroup with alarming frequency
+-- search Deja News for past messages about assignment expression.
+The reason for not allowing assignment in Python expressions
+is a common, hard-to-find bug in those other languages,
+caused by this construct:
+<P>
+<PRE>
+ if (x = 0) {
+ ...error handling...
+ }
+ else {
+ ...code that only works for nonzero x...
+ }
+</PRE>
+Many alternatives have been proposed. Most are hacks that save some
+typing but use arbitrary or cryptic syntax or keywords,
+and fail the simple criterion that I use for language change proposals:
+it should intuitively suggest the proper meaning to a human reader
+who has not yet been introduced with the construct.
+<P>
+The earliest time something can be done about this will be with
+Python 2.0 -- if it is decided that it is worth fixing.
+An interesting phenomenon is that most experienced Python programmers
+recognize the "while 1" idiom and don't seem to be missing the
+assignment in expression construct much; it's only the newcomers
+who express a strong desire to add this to the language.
+<P>
+One fairly elegant solution would be to introduce a new operator
+for assignment in expressions spelled ":=" -- this avoids the "="
+instead of "==" problem. It would have the same precedence
+as comparison operators but the parser would flag combination with
+other comparisons (without disambiguating parentheses) as an error.
+<P>
+Finally -- there's an alternative way of spelling this that seems
+attractive but is generally less robust than the "while 1" solution:
+<P>
+<PRE>
+ line = f.readline()
+ while line:
+ ...do something with line...
+ line = f.readline()
+</PRE>
+The problem with this is that if you change your mind about exactly
+how you get the next line (e.g. you want to change it into
+sys.stdin.readline()) you have to remember to change two places
+in your program -- the second one hidden at the bottom of the loop.

+<H2><A NAME="6.31">6.31. Why doesn't Python have a "with" statement like some other languages?</A></H2>
+Basically, because such a construct would be terribly ambiguous. Thanks to Carlos Ribeiro for the following remarks:
+<P>
+Some languages, such as Object Pascal, Delphi, and C++, use static types. So it is possible to know, in an unambiguous way, what member is being assigned in a "with" clause. This is the main point - the compiler <I>always</I> knows the scope of every variable at compile time.
+<P>
+Python uses dynamic types. It is impossible to know in advance which
+attribute will be referenced at runtime. Member attributes may be added or removed from objects on the fly. This would make it impossible to know, from a simple reading, what attribute is being referenced - a local one, a global one, or a member attribute.
+<P>
+For instance, take the following snippet (it is incomplete btw, just to
+give you the idea):
+<P>
+<PRE>
+ def with_is_broken(a):
+ with a:
+ print x
+</PRE>
+The snippet assumes that "a" must have a member attribute called "x".
+However, there is nothing in Python that guarantees that. What should
+happen if "a" is, let us say, an integer? And if I have a global variable named "x", will it end up being used inside the with block? As you see, the dynamic nature of Python makes such choices much harder.
+<P>
+The primary benefit of "with" and similar language features (reduction of code volume) can, however, easily be achieved in Python by assignment. Instead of:
+<P>
+<PRE>
+ function(args).dict[index][index].a = 21
+ function(args).dict[index][index].b = 42
+ function(args).dict[index][index].c = 63
+</PRE>
+would become:
+<P>
+<PRE>
+ ref = function(args).dict[index][index]
+ ref.a = 21
+ ref.b = 42
+ ref.c = 63
+</PRE>
+This also has the happy side-effect of increasing execution speed, since name bindings are resolved at run-time in Python, and the second method only needs to perform the resolution once. If the referenced object does not have a, b and c attributes, of course, the end result is still a run-time exception.

+The Global Interpreter Lock (GIL) is often seen as a hindrance to
+Python's deployment on high-end multiprocessor server machines,
+because a multi-threaded Python program effectively only uses
+one CPU, due to the insistence that (almost) all Python code
+can only run while the GIL is held.
+<P>
+Back in the days of Python 1.5, Greg Stein actually implemented
+a comprehensive patch set ("free threading")
+that removed the GIL, replacing it with
+fine-grained locking. Unfortunately, even on Windows (where locks
+are very efficient) this ran ordinary Python code about twice as
+slow as the interpreter using the GIL. On Linux the performance
+loss was even worse (pthread locks aren't as efficient).
+<P>
+Since then, the idea of getting rid of the GIL has occasionally
+come up but nobody has found a way to deal with the expected slowdown;
+Greg's free threading patch set has not been kept up-to-date for
+later Python versions.
+<P>
+This doesn't mean that you can't make good use of Python on
+multi-CPU machines! You just have to be creative with dividing
+the work up between multiple <I>processes</I> rather than multiple
+<I>threads</I>.
+<P>
+<P>
+It has been suggested that the GIL should be a per-interpreter-state
+lock rather than truly global; interpreters then wouldn't be able
+to share objects. Unfortunately, this isn't likely to happen either.
+<P>
+It would be a tremendous amount of work, because many object
+implementations currently have global state. E.g. small ints and
+small strings are cached; these caches would have to be moved to the
+interpreter state. Other object types have their own free list; these
+free lists would have to be moved to the interpreter state. And so
+on.
+<P>
+And I doubt that it can even be done in finite time, because the same
+problem exists for 3rd party extensions. It is likely that 3rd party
+extensions are being written at a faster rate than you can convert
+them to store all their global state in the interpreter state.
+<P>
+And finally, once you have multiple interpreters not sharing any
+state, what have you gained over running each interpreter
+in a separate process?

+I haven't heard about these, except I remember hearing about an
+OS/9 port and a port to Vxworks (both operating systems for embedded
+systems). If you're interested in any of this, go directly to the
+newsgroup and ask there, you may find exactly what you need. For
+example, a port to MPE/iX 5.0 on HP3000 computers was just announced,
+see <A HREF="http://www.allegro.com/software">http://www.allegro.com/software</A>/.
+<P>
+On the IBM mainframe side, for Z/OS there's a port of python 1.4 that goes with their open-unix package, formely OpenEdition MVS, (<A HREF="http://www-1.ibm.com/servers/eserver/zseries/zos/unix/python.html">http://www-1.ibm.com/servers/eserver/zseries/zos/unix/python.html</A>). On a side note, there's also a java vm ported - so, in theory, jython could run too.

+If you are running any version of Windows, then you have the wrong distribution. The FAQ lists current Windows versions. Notably, Pythonwin and wpy provide fully functional installations.
+<P>
+But if you are sure you have the only distribution with a hope of working on
+your system, then...
+<P>
+You still need to copy the files from the distribution directory
+"python/Lib" to your system. If you don't have the full distribution,
+you can get the file lib<version>.tar.gz from most ftp sites carrying
+Python; this is a subset of the distribution containing just those
+files, e.g. <A HREF="ftp://ftp.python.org/pub/python/src/lib1.4.tar.gz">ftp://ftp.python.org/pub/python/src/lib1.4.tar.gz</A>.
+<P>
+Once you have installed the library, you need to point sys.path to it.
+Assuming the library is in C:\misc\python\lib, the following commands
+will point your Python interpreter to it (note the doubled backslashes
+-- you can also use single forward slashes instead):
+<P>

+Regarding the same question for the PC, Kurt Wm. Hemr writes: "While
+anyone with a pulse could certainly figure out how to do the same on

+provided "scripts" is an "executable" directory for your server (which
+it usually is by default).
+The "-u" flag specifies unbuffered and binary mode for stdin - needed when working with binary data
+<P>
+In addition, it is recommended by people who would know that using ".py" may
+not be a good idea for the file extensions when used in this context
+(you might want to reserve *.py for support modules and use *.cgi or *.cgp
+for "main program" scripts).
+However, that issue is beyond this Windows FAQ entry.

+I've got a theory about why this happens, but it's only

+This is very sensitive to the compiler vendor, version and (perhaps)

+The Python 1.5.* DLLs (python15.dll) are all compiled

+("Freeze" is a program that allows you to ship a Python program
+as a single stand-alone executable file. It is <I>not</I> a compiler,
+your programs don't run any faster, but they are more easily
+distributable (to platforms with the same OS and CPU). Read the
+README file of the freeze program for more disclaimers.)
+<P>
+You can use freeze on Windows, but you must download the source
+tree (see <A HREF="http://www.python.org/download/download_source.html">http://www.python.org/download/download_source.html</A>).
+This is recommended for Python 1.5.2 (and betas thereof) only;
+older versions don't quite work.
+<P>
+You need the Microsoft VC++ 5.0 compiler (maybe it works with
+6.0 too). You probably need to build Python -- the project files

+<H2><A NAME="8.12">8.12. Is a *.pyd file the same as a DLL?</A></H2>
+Yes, .pyd files are dll's. But there are a few differences. If you
+have a DLL named foo.pyd, then it must have a function initfoo(). You
+can then write Python "import foo", and Python will search for foo.pyd
+(as well as foo.py, foo.pyc) and if it finds it, will attempt to call
+initfoo() to initialize it. You do not link your .exe with foo.lib,
+as that would cause Windows to require the DLL to be present.
+<P>
+Note that the search path for foo.pyd is PYTHONPATH, not the same as
+the path that Windows uses to search for foo.dll. Also, foo.pyd need
+not be present to run your program, whereas if you linked your program
+with a dll, the dll is required. Of course, foo.pyd is required if
+you want to say "import foo". In a dll, linkage is declared in the
+source code with __declspec(dllexport). In a .pyd, linkage is defined
+in a list of available functions.

+[Blake Coverett]
+<P>
+Win2K:
+<P>
+The standard installer already associates the .py extension with a file type
+(Python.File) and gives that file type an open command that runs the
+interpreter (D:\Program Files\Python\python.exe "%1" %*). This is enough to
+make scripts executable from the command prompt as 'foo.py'. If you'd
+rather be able to execute the script by simple typing 'foo' with no
+extension you need to add .py to the PATHEXT environment variable.
+<P>
+WinNT:
+<P>
+The steps taken by the installed as described above allow you do run a
+script with 'foo.py', but a long time bug in the NT command processor
+prevents you from redirecting the input or output of any script executed in
+this way. This is often important.
+<P>
+An appropriate incantation for making a Python script executable under WinNT
+is to give the file an extension of .cmd and add the following as the first
+line:

+This is a Microsoft DLL, and a notorious

+<H2><A NAME="8.16">8.16. How can I embed Python into a Windows application?</A></H2>
+Edward K. Ream <<A HREF="mailto:edream@tds.net">edream@tds.net</A>> writes
+<P>
+When '##' appears in a file name below, it is an abbreviated version number. For example, for Python 2.1.1, ## will be replaced by 21.
+<P>
+Embedding the Python interpreter in a Windows app can be summarized as
+follows:
+<P>
+1. Do _not_ build Python into your .exe file directly. On Windows,
+Python must be a DLL to handle importing modules that are themselves
+DLL's. (This is the first key undocumented fact.) Instead, link to
+python##.dll; it is typically installed in c:\Windows\System.
+<P>
+You can link to Python statically or dynamically. Linking statically
+means linking against python##.lib The drawback is that your app won't
+run if python##.dll does not exist on your system.
+<P>
+General note: python##.lib is the so-called "import lib" corresponding
+to python.dll. It merely defines symbols for the linker.
+<P>
+Borland note: convert python##.lib to OMF format using Coff2Omf.exe
+first.
+<P>
+Linking dynamically greatly simplifies link options; everything happens
+at run time. Your code must load python##.dll using the Windows
+LoadLibraryEx() routine. The code must also use access routines and
+data in python##.dll (that is, Python's C API's) using pointers
+obtained by the Windows GetProcAddress() routine. Macros can make
+using these pointers transparent to any C code that calls routines in
+Python's C API.
+<P>
+2. If you use SWIG, it is easy to create a Python "extension module"
+that will make the app's data and methods available to Python. SWIG
+will handle just about all the grungy details for you. The result is C
+code that you link _into your .exe file_ (!) You do _not_ have to
+create a DLL file, and this also simplifies linking.
+<P>
+3. SWIG will create an init function (a C function) whose name depends
+on the name of the extension module. For example, if the name of the
+module is leo, the init function will be called initleo(). If you use
+SWIG shadow classes, as you should, the init function will be called
+initleoc(). This initializes a mostly hidden helper class used by the
+shadow class.
+<P>
+The reason you can link the C code in step 2 into your .exe file is that
+calling the initialization function is equivalent to importing the
+module into Python! (This is the second key undocumented fact.)
+<P>
+4. In short, you can use the following code to initialize the Python
+interpreter with your extension module.
+<P>
+<PRE>
+ #include "python.h"
+ ...
+ Py_Initialize(); // Initialize Python.
+ initmyAppc(); // Initialize (import) the helper class.
+ PyRun_SimpleString("import myApp") ; // Import the shadow class.
+</PRE>
+5. There are two problems with Python's C API which will become apparent
+if you use a compiler other than MSVC, the compiler used to build
+python##.dll.
+<P>
+Problem 1: The so-called "Very High Level" functions that take FILE *
+arguments will not work in a multi-compiler environment; each compiler's
+notion of a struct FILE will be different. From an implementation
+standpoint these are very _low_ level functions.
+<P>
+Problem 2: SWIG generates the following code when generating wrappers to
+void functions:
+<P>
+<PRE>
+ Py_INCREF(Py_None);
+ _resultobj = Py_None;
+ return _resultobj;
+</PRE>
+Alas, Py_None is a macro that expands to a reference to a complex data
+structure called _Py_NoneStruct inside python##.dll. Again, this code
+will fail in a mult-compiler environment. Replace such code by:
+<P>
+<PRE>
+ return Py_BuildValue("");
+</PRE>
+It may be possible to use SWIG's %typemap command to make the change
+automatically, though I have not been able to get this to work (I'm a
+complete SWIG newbie).
+<P>
+6. Using a Python shell script to put up a Python interpreter window
+from inside your Windows app is not a good idea; the resulting window
+will be independent of your app's windowing system. Rather, you (or the
+wxPythonWindow class) should create a "native" interpreter window. It
+is easy to connect that window to the Python interpreter. You can
+redirect Python's i/o to _any_ object that supports read and write, so
+all you need is a Python object (defined in your extension module) that
+contains read() and write() methods.

+<H2><A NAME="8.18">8.18. How do I run a Python program under Windows?</A></H2>
+This is not necessarily quite the straightforward question it appears
+to be. If you are already familiar with running programs from the
+Windows command line then everything will seem really easy and
+obvious. If your computer experience is limited then you might need a
+little more guidance. Also there are differences between Windows 95,
+98, NT, ME, 2000 and XP which can add to the confusion. You might
+think of this as "why I pay software support charges" if you have a
+helpful and friendly administrator to help you set things up without
+having to understand all this yourself. If so, then great! Show them
+this page and it should be a done deal.
+<P>
+Unless you use some sort of integrated development environment (such
+as PythonWin or IDLE, to name only two in a growing family) then you
+will end up <I>typing</I> Windows commands into what is variously referred
+to as a "DOS window" or "Command prompt window". Usually you can
+create such a window from your Start menu (under Windows 2000 I use
+"Start | Programs | Accessories | Command Prompt"). You should be
+able to recognize when you have started such a window because you will
+see a Windows "command prompt", which usually looks like this:
+<P>
+<PRE>
+ C:\>
+</PRE>
+The letter may be different, and there might be other things after it,
+so you might just as easily see something like:
+<P>
+<PRE>
+ D:\Steve\Projects\Python>
+</PRE>
+depending on how your computer has been set up and what else you have
+recently done with it. Once you have started such a window, you are
+well on the way to running Python programs.
+<P>
+You need to realize that your Python scripts have to be processed by
+another program, usually called the "Python interpreter". The
+interpreter reads your script, "compiles" it into "Python bytecodes"
+(which are instructions for an imaginary computer known as the "Python
+Virtual Machine") and then executes the bytecodes to run your
+program. So, how do you arrange for the interpreter to handle your
+Python?
+<P>
+First, you need to make sure that your command window recognises the
+word "python" as an instruction to start the interpreter. If you have
+opened a command window, you should try entering the command:
+<P>
+<PRE>
+ python
+</PRE>
+and hitting return. If you then see something like:
+<P>
+<PRE>
+ Python 2.2 (#28, Dec 21 2001, 12:21:22) [MSC 32 bit (Intel)] on win32
+ Type "help", "copyright", "credits" or "license" for more information.
+ >>>
+</PRE>
+then this part of the job has been correctly managed during Python's
+installation process, and you have started the interpreter in
+"interactive mode". That means you can enter Python statements or
+expressions interactively and have them executed or evaluated while
+you wait. This is one of Python's strongest features, but it takes a
+little getting used to. Check it by entering a few expressions of your
+choice and seeing the results...
+<P>
+<PRE>
+ >>> print "Hello"
+ Hello
+ >>> "Hello" * 3
+ HelloHelloHello
+</PRE>
+When you want to end your interactive Python session, enter a
+terminator (hold the Ctrl key down while you enter a Z, then hit the
+"Enter" key) to get back to your Windows command prompt. You may also
+find that you have a Start-menu entry such as "Start | Programs |
+Python 2.2 | Python (command line)" that results in you seeing the
+">>>" prompt in a new window. If so, the window will disappear after
+you enter the terminator -- Windows runs a single "python" command in
+the window, which terminates when you terminate the interpreter.
+<P>
+If the "python" command, instead of displaying the interpreter prompt ">>>", gives you a message like
+<P>
+<PRE>
+ 'python' is not recognized as an internal or external command,
+ operable program or batch file.
+</PRE>
+or
+<P>
+<PRE>
+ Bad command or filename
+</PRE>
+then you need to make sure that your computer knows where to find the
+Python interpreter. To do this you will have to modify a setting
+called the PATH, which is a just list of directories where Windows
+will look for programs. Rather than just enter the right command every
+time you create a command window, you should arrange for Python's
+installation directory to be added to the PATH of every command window
+as it starts. If you installed Python fairly recently then the command
+<P>
+<PRE>
+ dir C:\py*
+</PRE>
+will probably tell you where it is installed. Alternatively, perhaps
+you made a note. Otherwise you will be reduced to a search of your
+whole disk ... break out the Windows explorer and use "Tools | Find"
+or hit the "Search" button and look for "python.exe". Suppose you
+discover that Python is installed in the C:\Python22 directory (the
+default at the time of writing) then you should make sure that
+entering the command
+<P>
+<PRE>
+ c:\Python22\python
+</PRE>
+starts up the interpreter as above (and don't forget you'll need a
+"CTRL-Z" and an "Enter" to get out of it). Once you have verified the
+directory, you need to add it to the start-up routines your computer
+goes through. For older versions of Windows the easiest way to do
+this is to edit the C:\AUTOEXEC.BAT file. You would want to add a line
+like the following to AUTOEXEC.BAT:
+<P>
+<PRE>
+ PATH C:\Python22;%PATH%
+</PRE>
+For Windows NT, 2000 and (I assume) XP, you will need to add a string
+such as
+<P>
+<PRE>
+ ;C:\Python22
+</PRE>
+to the current setting for the PATH environment variable, which you
+will find in the properties window of "My Computer" under the
+"Advanced" tab. Note that if you have sufficient privilege you might
+get a choice of installing the settings either for the Current User or
+for System. The latter is preferred if you want everybody to be able
+to run Python on the machine.
+<P>
+If you aren't confident doing any of these manipulations yourself, ask
+for help! At this stage you may or may not want to reboot your system
+to make absolutely sure the new setting has "taken" (don't you love
+the way Windows gives you these freqeuent coffee breaks). You probably
+won't need to for Windows NT, XP or 2000. You can also avoid it in
+earlier versions by editing the file C:\WINDOWS\COMMAND\CMDINIT.BAT
+instead of AUTOEXEC.BAT.
+<P>
+You should now be able to start a new command window, enter
+<P>
+<PRE>
+ python
+</PRE>
+at the "C:>" (or whatever) prompt, and see the ">>>" prompt that
+indicates the Python interpreter is reading interactive commands.
+<P>
+Let's suppose you have a program called "pytest.py" in directory
+"C:\Steve\Projects\Python". A session to run that program might look
+like this:
+<P>
+<PRE>
+ C:\> cd \Steve\Projects\Python
+ C:\Steve\Projects\Python> python pytest.py
+</PRE>
+Because you added a file name to the command to start the interpreter,
+when it starts up it reads the Python script in the named file,
+compiles it, executes it, and terminates (so you see another "C:\>"
+prompt). You might also have entered
+<P>
+<PRE>
+ C:\> python \Steve\Projects\Python\pytest.py
+</PRE>
+if you hadn't wanted to change your current directory.
+<P>
+Under NT, 2000 and XP you may well find that the installation process
+has also arranged that the command
+<P>
+<PRE>
+ pytest.py
+</PRE>
+(or, if the file isn't in the current directory)
+<P>
+<PRE>
+ C:\Steve\Projects\Python\pytest.py
+</PRE>
+will automatically recognize the ".py" extension and run the Python
+interpreter on the named file. Using this feature is fine, but <I>some</I>
+versions of Windows have bugs which mean that this form isn't exactly
+equivalent to using the interpreter explicitly, so be careful. Easier
+to remember, for now, that
+<P>
+<PRE>
+ python C:\Steve\Projects\Python\pytest.py
+</PRE>
+works pretty close to the same, and redirection will work (more)
+reliably.
+<P>
+The important things to remember are:
+<P>
+1. Start Python from the Start Menu, or make sure the PATH is set
+correctly so Windows can find the Python interpreter.
+<P>
+<PRE>
+ python
+</PRE>
+should give you a '>>>" prompt from the Python interpreter. Don't
+forget the CTRL-Z and ENTER to terminate the interpreter (and, if you
+started the window from the Start Menu, make the window disappear).
+<P>
+2. Once this works, you run programs with commands:
+<P>
+<PRE>
+ python {program-file}
+</PRE>
+3. When you know the commands to use you can build Windows shortcuts
+to run the Python interpreter on any of your scripts, naming
+particular working directories, and adding them to your menus, but
+that's another lessFAQ. Take a look at
+<P>
+<PRE>
+ python --help
+</PRE>
+if your needs are complex.
+<P>
+4. Interactive mode (where you see the ">>>" prompt) is best used
+<I>not</I> for running programs, which are better executed as in steps 2
+and 3, but for checking that individual statements and expressions do
+what you think they will, and for developing code by experiment.

+.TH PYGETTEXT 1 "" "pygettext 1.4"
+.SH NAME
+pygettext \- Python equivalent of xgettext(1)
+.SH SYNOPSIS
+.B pygettext
+[\fIOPTIONS\fR] \fIINPUTFILE \fR...
+.SH DESCRIPTION
+pygettext is deprecated. The current version of xgettext supports
+many languages, including Python.
+
+pygettext uses Python's standard tokenize module to scan Python
+source code, generating .pot files identical to what GNU xgettext generates
+for C and C++ code. From there, the standard GNU tools can be used.
+.PP
+pygettext searches only for _() by default, even though GNU xgettext
+recognizes the following keywords: gettext, dgettext, dcgettext,
+and gettext_noop. See the \fB\-k\fR/\fB\--keyword\fR flag below for how to
+augment this.
+.PP
+.SH OPTIONS
+.TP
+\fB\-a\fR, \fB\-\-extract\-all\fR
+Extract all strings.
+.TP
+\fB\-d\fR, \fB\-\-default\-domain\fR=\fINAME\fR
+Rename the default output file from messages.pot to name.pot.
+.TP
+\fB\-E\fR, \fB\-\-escape\fR
+Replace non-ASCII characters with octal escape sequences.
+.TP
+\fB\-D\fR, \fB\-\-docstrings\fR
+Extract module, class, method, and function docstrings.
+These do not need to be wrapped in _() markers, and in fact cannot
+be for Python to consider them docstrings. (See also the \fB\-X\fR option).
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Print this help message and exit.
+.TP
+\fB\-k\fR, \fB\-\-keyword\fR=\fIWORD\fR
+Keywords to look for in addition to the default set, which are: _
+.IP
+You can have multiple \fB\-k\fR flags on the command line.
+.TP
+\fB\-K\fR, \fB\-\-no\-default\-keywords\fR
+Disable the default set of keywords (see above).
+Any keywords explicitly added with the \fB\-k\fR/\fB\--keyword\fR option
+are still recognized.
+.TP
+\fB\-\-no\-location\fR
+Do not write filename/lineno location comments.
+.TP
+\fB\-n\fR, \fB\-\-add\-location\fR
+Write filename/lineno location comments indicating where each
+extracted string is found in the source. These lines appear before
+each msgid. The style of comments is controlled by the
+\fB\-S\fR/\fB\--style\fR option. This is the default.
+.TP
+\fB\-o\fR, \fB\-\-output\fR=\fIFILENAME\fR
+Rename the default output file from messages.pot to FILENAME.
+If FILENAME is `-' then the output is sent to standard out.
+.TP
+\fB\-p\fR, \fB\-\-output\-dir\fR=\fIDIR\fR
+Output files will be placed in directory DIR.
+.TP
+\fB\-S\fR, \fB\-\-style\fR=\fISTYLENAME\fR
+Specify which style to use for location comments.
+Two styles are supported:
+.RS
+.IP \(bu 4
+Solaris # File: filename, line: line-number
+.IP \(bu 4
+GNU #: filename:line
+.RE
+.IP
+The style name is case insensitive.
+GNU style is the default.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Print the names of the files being processed.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Print the version of pygettext and exit.
+.TP
+\fB\-w\fR, \fB\-\-width\fR=\fICOLUMNS\fR
+Set width of output to columns.
+.TP
+\fB\-x\fR, \fB\-\-exclude\-file\fR=\fIFILENAME\fR
+Specify a file that contains a list of strings that are not be
+extracted from the input files. Each string to be excluded must
+appear on a line by itself in the file.
+.TP
+\fB\-X\fR, \fB\-\-no\-docstrings\fR=\fIFILENAME\fR
+Specify a file that contains a list of files (one per line) that
+should not have their docstrings extracted. This is only useful in
+conjunction with the \fB\-D\fR option above.
+.PP
+If `INPUTFILE' is -, standard input is read.
+.SH BUGS
+pygettext attempts to be option and feature compatible with GNU xgettext
+where ever possible. However some options are still missing or are not fully
+implemented. Also, xgettext's use of command line switches with option
+arguments is broken, and in these cases, pygettext just defines additional
+switches.
+.SH AUTHOR
+pygettext is written by Barry Warsaw <barry@zope.com>.
+.PP
+Joonas Paalasmaa <joonas.paalasmaa@iki.fi> put this manual page together
+based on "pygettext --help".

+Document: @PVER@-ext
+Title: Extending and Embedding the Python Interpreter (v@VER@)
+Author: Guido van Rossum
+Abstract: This document describes how to write modules in C or C++ to extend
+ the Python interpreter with new modules. Those modules can define
+ new functions but also new object types and their methods. The
+ document also describes how to embed the Python interpreter in
+ another application, for use as an extension language. Finally,
+ it shows how to compile and link extension modules so that they
+ can be loaded dynamically (at run time) into the interpreter, if
+ the underlying operating system supports this feature.

++Why do lambdas defined in a loop with different values all return the same result?
++----------------------------------------------------------------------------------
++
++Assume you use a for loop to define a few different lambdas (or even plain
++functions), e.g.::
++
++ squares = []
++ for x in range(5):
++ squares.append(lambda: x**2)
++
++This gives you a list that contains 5 lambdas that calculate ``x**2``. You
++might expect that, when called, they would return, respectively, ``0``, ``1``,
++``4``, ``9``, and ``16``. However, when you actually try you will see that
++they all return ``16``::
++
++ >>> squares[2]()
++ 16
++ >>> squares[4]()
++ 16
++
++This happens because ``x`` is not local to the lambdas, but is defined in
++the outer scope, and it is accessed when the lambda is called --- not when it
++is defined. At the end of the loop, the value of ``x`` is ``4``, so all the
++functions now return ``4**2``, i.e. ``16``. You can also verify this by
++changing the value of ``x`` and see how the results of the lambdas change::
++
++ >>> x = 8
++ >>> squares[2]()
++ 64
++
++In order to avoid this, you need to save the values in variables local to the
++lambdas, so that they don't rely on the value of the global ``x``::
++
++ squares = []
++ for x in range(5):
++ squares.append(lambda n=x: n**2)
++
++Here, ``n=x`` creates a new variable ``n`` local to the lambda and computed
++when the lambda is defined so that it has the same value that ``x`` had at
++that point in the loop. This means that the value of ``n`` will be ``0``
++in the first lambda, ``1`` in the second, ``2`` in the third, and so on.
++Therefore each lambda will now return the correct result::
++
++ >>> squares[2]()
++ 4
++ >>> squares[4]()
++ 16
++
++Note that this behaviour is not peculiar to lambdas, but applies to regular
++functions too.

+-of Windows the easiest way to do this is to edit the ``C:\AUTOEXEC.BAT``
+-file. You would want to add a line like the following to ``AUTOEXEC.BAT``::
++an "Enter" to get out of it). Once you have verified the directory, you can
++add it to the system path to make it easier to start Python by just running
++the ``python`` command. This is currently an option in the installer as of
++CPython 3.3.
+
+- PATH C:\Python23;%PATH%
+-
+-For Windows NT, 2000 and (I assume) XP, you will need to add a string such as ::
+-
+- ;C:\Python23
+-
+-to the current setting for the PATH environment variable, which you will find in
+-the properties window of "My Computer" under the "Advanced" tab. Note that if
+-you have sufficient privilege you might get a choice of installing the settings
+-either for the Current User or for System. The latter is preferred if you want
+-everybody to be able to run Python on the machine.
+-
+-If you aren't confident doing any of these manipulations yourself, ask for help!
+-At this stage you may want to reboot your system to make absolutely sure the new
+-setting has taken effect. You probably won't need to reboot for Windows NT, XP
+-or 2000. You can also avoid it in earlier versions by editing the file
+-``C:\WINDOWS\COMMAND\CMDINIT.BAT`` instead of ``AUTOEXEC.BAT``.
+-
+-You should now be able to start a new command window, enter ``python`` at the
+-``C:\>`` (or whatever) prompt, and see the ``>>>`` prompt that indicates the
+-Python interpreter is reading interactive commands.
+-
+-Let's suppose you have a program called ``pytest.py`` in directory
+-``C:\Steve\Projects\Python``. A session to run that program might look like
+-this::
+-
+- C:\> cd \Steve\Projects\Python
+- C:\Steve\Projects\Python> python pytest.py
+-
+-Because you added a file name to the command to start the interpreter, when it
+-starts up it reads the Python script in the named file, compiles it, executes
+-it, and terminates, so you see another ``C:\>`` prompt. You might also have
+-entered ::
+-
+- C:\> python \Steve\Projects\Python\pytest.py
+-
+-if you hadn't wanted to change your current directory.
+-
+-Under NT, 2000 and XP you may well find that the installation process has also
+-arranged that the command ``pytest.py`` (or, if the file isn't in the current
+-directory, ``C:\Steve\Projects\Python\pytest.py``) will automatically recognize
+-the ".py" extension and run the Python interpreter on the named file. Using this
+-feature is fine, but *some* versions of Windows have bugs which mean that this
+-form isn't exactly equivalent to using the interpreter explicitly, so be
+-careful.
+-
+-The important things to remember are:
+-
+-1. Start Python from the Start Menu, or make sure the PATH is set correctly so
+- Windows can find the Python interpreter. ::
+-
+- python
+-
+- should give you a '>>>' prompt from the Python interpreter. Don't forget the
+- CTRL-Z and ENTER to terminate the interpreter (and, if you started the window
+- from the Start Menu, make the window disappear).
+-
+-2. Once this works, you run programs with commands::
+-
+- python {program-file}
+-
+-3. When you know the commands to use you can build Windows shortcuts to run the
+- Python interpreter on any of your scripts, naming particular working
+- directories, and adding them to your menus. Take a look at ::
+-
+- python --help
+-
+- if your needs are complex.
+-
+-4. Interactive mode (where you see the ``>>>`` prompt) is best used for checking
+- that individual statements and expressions do what you think they will, and
+- for developing code by experiment.

+ ----------------------------------------
+

++On Windows, the standard Python installer already associates the .py
+ extension with a file type (Python.File) and gives that file type an open
+ command that runs the interpreter (``D:\Program Files\Python\python.exe "%1"
+ %*``). This is enough to make scripts executable from the command prompt as
+ 'foo.py'. If you'd rather be able to execute the script by simple typing 'foo'

+-On Windows NT, the steps taken by the installer as described above allow you to

+-
+-Run regedt32 and go to::

+-
+-and enter the following line (making any specific changes that your system may
+-need)::

+- .py :REG_SZ: c:\<path to python>\python.exe -u %s %s
+-
+-This line will allow you to call your script with a simple reference like:
+-``http://yourserver/scripts/yourscript.py`` provided "scripts" is an
+-"executable" directory for your server (which it usually is by default). The
+-:option:`-u` flag specifies unbuffered and binary mode for stdin - needed when
+-working with binary data.
+-
+-In addition, it is recommended that using ".py" may not be a good idea for the
+-file extensions when used in this context (you might want to reserve ``*.py``
+-for support modules and use ``*.cgi`` or ``*.cgp`` for "main program" scripts).

++Implementing structured logging
++-------------------------------
++
++Although most logging messages are intended for reading by humans, and thus not
++readily machine-parseable, there might be cirumstances where you want to output
++messages in a structured format which *is* capable of being parsed by a program
++(without needing complex regular expressions to parse the log message). This is
++straightforward to achieve using the logging package. There are a number of
++ways in which this could be achieved, but the following is a simple approach
++which uses JSON to serialise the event in a machine-parseable manner::
++
++ import json
++ import logging
++
++ class StructuredMessage(object):
++ def __init__(self, message, **kwargs):
++ self.message = message
++ self.kwargs = kwargs
++
++ def __str__(self):
++ return '%s >>> %s' % (self.message, json.dumps(self.kwargs))
++
++ _ = StructuredMessage # optional, to improve readability
++
++ logging.basicConfig(level=logging.INFO, format='%(message)s')
++ logging.info(_('message 1', foo='bar', bar='baz', num=123, fnum=123.456))
++
++If the above script is run, it prints::
++
++ message 1 >>> {"fnum": 123.456, "num": 123, "bar": "baz", "foo": "bar"}
++
++Note that the order of items might be different according to the version of
++Python used.
++
++If you need more specialised processing, you can use a custom JSON encoder,
++as in the following complete example::
++
++ from __future__ import unicode_literals
++
++ import json
++ import logging
++
++ # This next bit is to ensure the script runs unchanged on 2.x and 3.x
++ try:
++ unicode
++ except NameError:
++ unicode = str
++
++ class Encoder(json.JSONEncoder):
++ def default(self, o):
++ if isinstance(o, set):
++ return tuple(o)
++ elif isinstance(o, unicode):
++ return o.encode('unicode_escape').decode('ascii')
++ return super(Encoder, self).default(o)
++
++ class StructuredMessage(object):
++ def __init__(self, message, **kwargs):
++ self.message = message
++ self.kwargs = kwargs
++
++ def __str__(self):
++ s = Encoder().encode(self.kwargs)
++ return '%s >>> %s' % (self.message, s)
++
++ _ = StructuredMessage # optional, to improve readability
++
++ def main():
++ logging.basicConfig(level=logging.INFO, format='%(message)s')
++ logging.info(_('message 1', set_value=set([1, 2, 3]), snowman='\u2603'))
++
++ if __name__ == '__main__':
++ main()
++
++When the above script is run, it prints::
++
++ message 1 >>> {"snowman": "\u2603", "set_value": [1, 2, 3]}
++
++Note that the order of items might be different according to the version of
++Python used.

++Basic Examples
++--------------
++
++The following example shows how the :ref:`command-line-interface`
++can be used to compare three different expressions:
++
++.. code-block:: sh
++
++ $ python -m timeit '"-".join(str(n) for n in range(100))'
++ 10000 loops, best of 3: 40.3 usec per loop
++ $ python -m timeit '"-".join([str(n) for n in range(100)])'
++ 10000 loops, best of 3: 33.4 usec per loop
++ $ python -m timeit '"-".join(map(str, range(100)))'
++ 10000 loops, best of 3: 25.2 usec per loop
++
++This can be achieved from the :ref:`python-interface` with::
++
++ >>> import timeit
++ >>> timeit.timeit('"-".join(str(n) for n in range(100))', number=10000)
++ 0.8187260627746582
++ >>> timeit.timeit('"-".join([str(n) for n in range(100)])', number=10000)
++ 0.7288308143615723
++ >>> timeit.timeit('"-".join(map(str, range(100)))', number=10000)
++ 0.5858950614929199
++
++Note however that :mod:`timeit` will automatically determine the number of
++repetitions only when the command-line interface is used. In the

+-The test case and test fixture concepts are supported through the

+-existing test code with a :mod:`unittest`\ -driven framework. When building test
+-fixtures using :class:`TestCase`, the :meth:`~TestCase.setUp` and
+-:meth:`~TestCase.tearDown` methods can be overridden to provide initialization
+-and cleanup for the fixture. With :class:`FunctionTestCase`, existing functions
+-can be passed to the constructor for these purposes. When the test is run, the
+-fixture initialization is run first; if it succeeds, the cleanup method is run
+-after the test has been executed, regardless of the outcome of the test. Each
+-instance of the :class:`TestCase` will only be used to run a single test method,
+-so a new fixture is created for each test.

+-Test suites are implemented by the :class:`TestSuite` class. This class allows
+-individual tests and test suites to be aggregated; when the suite is executed,
+-all tests added directly to the suite and in "child" test suites are run.

+-A test runner is an object that provides a single method,

+-object as a parameter, and returns a result object. The class

+-results - a 5 where you expected a 6. :dfn:`Errors` are caused by incorrect

++:ref:`Function annotations <function>` are completely optional,
++arbitrary metadata information about user-defined functions. Neither Python
++itself nor the standard library use function annotations in any way; this
++section just shows the syntax. Third-party projects are free to use function
++annotations for documentation, type checking, and other uses.
++
++Annotations are stored in the :attr:`__annotations__` attribute of the function
++as a dictionary and have no effect on any other part of the function. Parameter
++annotations are defined by a colon after the parameter name, followed by an
++expression evaluating to the value of the annotation. Return annotations are
++defined by a literal ``->``, followed by an expression, between the parameter
++list and the colon denoting the end of the :keyword:`def` statement. The
++following example has a positional argument, a keyword argument, and the return
++value annotated with nonsense::
++
++ >>> def f(ham: 42, eggs: int = 'spam') -> "Nothing to see here":
++ ... print("Annotations:", f.__annotations__)

++PEP 397: Python Launcher for Windows
++====================================
++
++The Python 3.3 Windows installer now includes a ``py`` launcher application
++that can be used to launch Python applications in a version independent
++fashion.
++
++This launcher is invoked implicitly when double-clicking ``*.py`` files.
++If only a single Python version is installed on the system, that version
++will be used to run the file. If multiple versions are installed, the most
++recent version is used by default, but this can be overridden by including
++a Unix-style "shebang line" in the Python script.
++
++The launcher can also be used explicitly from the command line as the ``py``
++application. Running ``py`` follows the same version selection rules as
++implicitly launching scripts, but a more specific version can be selected
++by passing appropriate arguments (such as ``-3`` to request Python 3 when
++Python 2 is also installed, or ``-2.6`` to specifclly request an earlier
++Python version when a more recent version is installed).
++
++In addition to the launcher, the Windows installer now includes an
++option to add the newly installed Python to the system PATH (contributed
++by Brian Curtin in :issue:`3561`).

++PEP 421: Adding sys.implementation
++==================================
++
++A new attribute on the :mod:`sys` module exposes details specific to the
++implementation of the currently running interpreter. The initial set of
++attributes on :attr:`sys.implementation` are ``name``, ``version``,
++``hexversion``, and ``cache_tag``.
++
++The intention of ``sys.implementation`` is to consolidate into one namespace
++the implementation-specific data used by the standard library. This allows
++different Python implementations to share a single standard library code base
++much more easily. In its initial state, ``sys.implementation`` holds only a
++small portion of the implementation-specific data. Over time that ratio will
++shift in order to make the standard library more portable.
++
++One example of improved standard library portability is ``cache_tag``. As of
++Python 3.3, ``sys.implementation.cache_tag`` is used by :mod:`importlib` to
++support :pep:`3147` compliance. Any Python implementation that uses
++``importlib`` for its built-in import system may use ``cache_tag`` to control
++the caching behavior for modules.
++
++SimpleNamespace
++---------------

++
++
++Other Language Changes
++======================
++
++Some smaller changes made to the core Python language are:
++
++* Added support for Unicode name aliases and named sequences.
++ Both :func:`unicodedata.lookup()` and ``'\N{...}'`` now resolve name aliases,
++ and :func:`unicodedata.lookup()` resolves named sequences too.
++
++ (Contributed by Ezio Melotti in :issue:`12753`)
++
++* Unicode database updated to UCD version 6.1.0
++
++* Equality comparisons on :func:`range` objects now return a result reflecting
++ the equality of the underlying sequences generated by those range objects.
++ (:issue:`13201`)
++
++* The ``count()``, ``find()``, ``rfind()``, ``index()`` and ``rindex()``
++ methods of :class:`bytes` and :class:`bytearray` objects now accept an
++ integer between 0 and 255 as their first argument.
++
++ (Contributed by Petri Lehtinen in :issue:`12170`)
++
++* The ``rjust()``, ``ljust()``, and ``center()`` methods of :class:`bytes`
++ and :class:`bytearray` now accept a :class:`bytearray` for the ``fill``
++ argument. (Contributed by Petri Lehtinen in :issue:`12380`.)
++
++* New methods have been added to :class:`list` and :class:`bytearray`:
++ ``copy()`` and ``clear()`` (:issue:`10516`). Consequently,
++ :class:`~collections.abc.MutableSequence` now also defines a
++ :meth:`~collections.abc.MutableSequence.clear` method (:issue:`11388`).
++
++* Raw bytes literals can now be written ``rb"..."`` as well as ``br"..."``.
++
++ (Contributed by Antoine Pitrou in :issue:`13748`.)
++
++* :meth:`dict.setdefault` now does only one lookup for the given key, making
++ it atomic when used with built-in types.
++
++ (Contributed by Filip Gruszczyński in :issue:`13521`.)
++
++* The error messages produced when a function call does not match the function
++ signature have been significantly improved.
++
++ (Contributed by Benjamin Peterson.)
++
++
++A Finer-Grained Import Lock
++===========================
++
++Previous versions of CPython have always relied on a global import lock.
++This led to unexpected annoyances, such as deadlocks when importing a module
++would trigger code execution in a different thread as a side-effect.
++Clumsy workarounds were sometimes employed, such as the
++:c:func:`PyImport_ImportModuleNoBlock` C API function.
++
++In Python 3.3, importing a module takes a per-module lock. This correctly
++serializes importation of a given module from multiple threads (preventing
++the exposure of incompletely initialized modules), while eliminating the
++aforementioned annoyances.
++
++(Contributed by Antoine Pitrou in :issue:`9260`.)
++
++
++Builtin functions and types
++===========================
++
++* :func:`open` gets a new *opener* parameter: the underlying file descriptor
++ for the file object is then obtained by calling *opener* with (*file*,
++ *flags*). It can be used to use custom flags like :data:`os.O_CLOEXEC` for
++ example. The ``'x'`` mode was added: open for exclusive creation, failing if
++ the file already exists.
++* :func:`print`: added the *flush* keyword argument. If the *flush* keyword
++ argument is true, the stream is forcibly flushed.
++* :func:`hash`: hash randomization is enabled by default, see
++ :meth:`object.__hash__` and :envvar:`PYTHONHASHSEED`.
++* The :class:`str` type gets a new :meth:`~str.casefold` method: return a
++ casefolded copy of the string, casefolded strings may be used for caseless
++ matching. For example, ``'ß'.casefold()`` returns ``'ss'``.
++* The sequence documentation has been substantially rewritten to better
++ explain the binary/text sequence distinction and to provide specific
++ documentation sections for the individual builtin sequence types
++ (:issue:`4966`)
++
++
++New Modules
++===========
++
++faulthandler
++------------
++
++This new debug module :mod:`faulthandler` contains functions to dump Python tracebacks explicitly,
++on a fault (a crash like a segmentation fault), after a timeout, or on a user
++signal. Call :func:`faulthandler.enable` to install fault handlers for the
++:const:`SIGSEGV`, :const:`SIGFPE`, :const:`SIGABRT`, :const:`SIGBUS`, and
++:const:`SIGILL` signals. You can also enable them at startup by setting the
++:envvar:`PYTHONFAULTHANDLER` environment variable or by using :option:`-X`
++``faulthandler`` command line option.
++
++Example of a segmentation fault on Linux: ::
++
++ $ python -q -X faulthandler
++ >>> import ctypes
++ >>> ctypes.string_at(0)
++ Fatal Python error: Segmentation fault
++
++ Current thread 0x00007fb899f39700:
++ File "/home/python/cpython/Lib/ctypes/__init__.py", line 486 in string_at
++ File "<stdin>", line 1 in <module>
++ Segmentation fault
++
++
++ipaddress
++---------
++
++The new :mod:`ipaddress` module provides tools for creating and manipulating
++objects representing IPv4 and IPv6 addresses, networks and interfaces (i.e.
++an IP address associated with a specific IP subnet).
++
++(Contributed by Google and Peter Moody in :pep:`3144`)
++
++lzma
++----
++
++The newly-added :mod:`lzma` module provides data compression and decompression
++using the LZMA algorithm, including support for the ``.xz`` and ``.lzma``
++file formats.
++
++(Contributed by Nadeem Vawda and Per Øyvind Karlsen in :issue:`6715`)
++
++
++Improved Modules
++================
++
++abc
++---
++
++Improved support for abstract base classes containing descriptors composed with
++abstract methods. The recommended approach to declaring abstract descriptors is
++now to provide :attr:`__isabstractmethod__` as a dynamically updated
++property. The built-in descriptors have been updated accordingly.
++
++ * :class:`abc.abstractproperty` has been deprecated, use :class:`property`
++ with :func:`abc.abstractmethod` instead.
++ * :class:`abc.abstractclassmethod` has been deprecated, use
++ :class:`classmethod` with :func:`abc.abstractmethod` instead.
++ * :class:`abc.abstractstaticmethod` has been deprecated, use
++ :class:`staticmethod` with :func:`abc.abstractmethod` instead.
++
++(Contributed by Darren Dale in :issue:`11610`)
++
++:meth:`abc.ABCMeta.register` now returns the registered subclass, which means
++it can now be used as a class decorator (:issue:`10868`).
++
++
++array
++-----
++
++The :mod:`array` module supports the :c:type:`long long` type using ``q`` and
++``Q`` type codes.
++
++(Contributed by Oren Tirosh and Hirokazu Yamamoto in :issue:`1172711`)
++
++
++base64
++------
++
++ASCII-only Unicode strings are now accepted by the decoding functions of the
++:mod:`base64` modern interface. For example, ``base64.b64decode('YWJj')``
++returns ``b'abc'``. (Contributed by Catalin Iacob in :issue:`13641`.)
++
++
++binascii
++--------
++
++In addition to the binary objects they normally accept, the ``a2b_`` functions
++now all also accept ASCII-only strings as input. (Contributed by Antoine
++Pitrou in :issue:`13637`.)
++
++
++bz2
++---
++
++The :mod:`bz2` module has been rewritten from scratch. In the process, several
++new features have been added:
++
++* New :func:`bz2.open` function: open a bzip2-compressed file in binary or
++ text mode.
++
++* :class:`bz2.BZ2File` can now read from and write to arbitrary file-like
++ objects, by means of its constructor's *fileobj* argument.
++
++ (Contributed by Nadeem Vawda in :issue:`5863`)
++
++* :class:`bz2.BZ2File` and :func:`bz2.decompress` can now decompress
++ multi-stream inputs (such as those produced by the :program:`pbzip2` tool).
++ :class:`bz2.BZ2File` can now also be used to create this type of file, using
++ the ``'a'`` (append) mode.
++
++ (Contributed by Nir Aides in :issue:`1625`)
++
++* :class:`bz2.BZ2File` now implements all of the :class:`io.BufferedIOBase` API,
++ except for the :meth:`detach` and :meth:`truncate` methods.
++
++
++codecs
++------
++
++The :mod:`~encodings.mbcs` codec has been rewritten to handle correctly
++``replace`` and ``ignore`` error handlers on all Windows versions. The
++:mod:`~encodings.mbcs` codec now supports all error handlers, instead of only
++``replace`` to encode and ``ignore`` to decode.
++
++A new Windows-only codec has been added: ``cp65001`` (:issue:`13216`). It is the
++Windows code page 65001 (Windows UTF-8, ``CP_UTF8``). For example, it is used
++by ``sys.stdout`` if the console output code page is set to cp65001 (e.g., using
++``chcp 65001`` command).
++
++Multibyte CJK decoders now resynchronize faster. They only ignore the first
++byte of an invalid byte sequence. For example, ``b'\xff\n'.decode('gb2312',
++'replace')`` now returns a ``\n`` after the replacement character.
++
++(:issue:`12016`)
++
++Incremental CJK codec encoders are no longer reset at each call to their
++encode() methods. For example::
++
++ $ ./python -q
++ >>> import codecs
++ >>> encoder = codecs.getincrementalencoder('hz')('strict')
++ >>> b''.join(encoder.encode(x) for x in '\u52ff\u65bd\u65bc\u4eba\u3002 Bye.')
++ b'~{NpJ)l6HK!#~} Bye.'
++
++This example gives ``b'~{Np~}~{J)~}~{l6~}~{HK~}~{!#~} Bye.'`` with older Python
++versions.
++
++(:issue:`12100`)
++
++The ``unicode_internal`` codec has been deprecated.
++
++
++collections
++-----------
++
++Addition of a new :class:`~collections.ChainMap` class to allow treating a
++number of mappings as a single unit. (Written by Raymond Hettinger for
++:issue:`11089`, made public in :issue:`11297`)
++
++The abstract base classes have been moved in a new :mod:`collections.abc`
++module, to better differentiate between the abstract and the concrete
++collections classes. Aliases for ABCs are still present in the
++:mod:`collections` module to preserve existing imports. (:issue:`11085`)
++
++.. XXX addition of __slots__ to ABCs not recorded here: internal detail
++
++The :class:`~collections.Counter` class now supports the unary ``+`` and ``-``
++operators, as well as the in-place operators ``+=``, ``-=``, ``|=``, and
++``&=``. (Contributed by Raymond Hettinger in :issue:`13121`.)
++
++
++contextlib
++----------
++
++:class:`~contextlib.ExitStack` now provides a solid foundation for
++programmatic manipulation of context managers and similar cleanup
++functionality. Unlike the previous ``contextlib.nested`` API (which was
++deprecated and removed), the new API is designed to work correctly
++regardless of whether context managers acquire their resources in
++their ``__init__`` method (for example, file objects) or in their
++``__enter__`` method (for example, synchronisation objects from the
++:mod:`threading` module).
++
++(:issue:`13585`)
++
++
++crypt
++-----
++
++Addition of salt and modular crypt format (hashing method) and the :func:`~crypt.mksalt`
++function to the :mod:`crypt` module.
++
++(:issue:`10924`)
++
++curses
++------
++
++ * If the :mod:`curses` module is linked to the ncursesw library, use Unicode
++ functions when Unicode strings or characters are passed (e.g.
++ :c:func:`waddwstr`), and bytes functions otherwise (e.g. :c:func:`waddstr`).
++ * Use the locale encoding instead of ``utf-8`` to encode Unicode strings.
++ * :class:`curses.window` has a new :attr:`curses.window.encoding` attribute.
++ * The :class:`curses.window` class has a new :meth:`~curses.window.get_wch`
++ method to get a wide character
++ * The :mod:`curses` module has a new :meth:`~curses.unget_wch` function to
++ push a wide character so the next :meth:`~curses.window.get_wch` will return
++ it
++
++(Contributed by Iñigo Serna in :issue:`6755`)
++
++datetime
++--------
++
++ * Equality comparisons between naive and aware :class:`~datetime.datetime`
++ instances now return :const:`False` instead of raising :exc:`TypeError`
++ (:issue:`15006`).
++ * New :meth:`datetime.datetime.timestamp` method: Return POSIX timestamp
++ corresponding to the :class:`~datetime.datetime` instance.
++ * The :meth:`datetime.datetime.strftime` method supports formatting years
++ older than 1000.
++ * The :meth:`datetime.datetime.astimezone` method can now be
++ called without arguments to convert datetime instance to the system
++ timezone.
++
++
++.. _new-decimal:
++
++decimal
++-------
++
++:issue:`7652` - integrate fast native decimal arithmetic.
++ C-module and libmpdec written by Stefan Krah.
++
++The new C version of the decimal module integrates the high speed libmpdec
++library for arbitrary precision correctly-rounded decimal floating point
++arithmetic. libmpdec conforms to IBM's General Decimal Arithmetic Specification.
++
++Performance gains range from 10x for database applications to 100x for
++numerically intensive applications. These numbers are expected gains
++for standard precisions used in decimal floating point arithmetic. Since
++the precision is user configurable, the exact figures may vary. For example,
++in integer bignum arithmetic the differences can be significantly higher.
++
++The following table is meant as an illustration. Benchmarks are available
++at http://www.bytereef.org/mpdecimal/quickstart.html.
++
++ +---------+-------------+--------------+-------------+
++ | | decimal.py | _decimal | speedup |
++ +=========+=============+==============+=============+
++ | pi | 42.02s | 0.345s | 120x |

++ | telco | 172.19s | 5.68s | 30x |
++ +---------+-------------+--------------+-------------+
++ | psycopg | 3.57s | 0.29s | 12x |
++ +---------+-------------+--------------+-------------+
++
++Features
++~~~~~~~~
++
++* The :exc:`~decimal.FloatOperation` signal optionally enables stricter
++ semantics for mixing floats and Decimals.
++
++* If Python is compiled without threads, the C version automatically
++ disables the expensive thread local context machinery. In this case,
++ the variable :data:`~decimal.HAVE_THREADS` is set to False.
++
++API changes
++~~~~~~~~~~~
++
++* The C module has the following context limits, depending on the machine
++ architecture:
++
++ +-------------------+---------------------+------------------------------+
++ | | 32-bit | 64-bit |
++ +===================+=====================+==============================+
++ | :const:`MAX_PREC` | :const:`425000000` | :const:`999999999999999999` |
++ +-------------------+---------------------+------------------------------+
++ | :const:`MAX_EMAX` | :const:`425000000` | :const:`999999999999999999` |
++ +-------------------+---------------------+------------------------------+
++ | :const:`MIN_EMIN` | :const:`-425000000` | :const:`-999999999999999999` |
++ +-------------------+---------------------+------------------------------+
++
++* In the context templates (:class:`~decimal.DefaultContext`,
++ :class:`~decimal.BasicContext` and :class:`~decimal.ExtendedContext`)
++ the magnitude of :attr:`~decimal.Context.Emax` and
++ :attr:`~decimal.Context.Emin` has changed to :const:`999999`.
++
++* The :class:`~decimal.Decimal` constructor in decimal.py does not observe
++ the context limits and converts values with arbitrary exponents or precision
++ exactly. Since the C version has internal limits, the following scheme is
++ used: If possible, values are converted exactly, otherwise
++ :exc:`~decimal.InvalidOperation` is raised and the result is NaN. In the
++ latter case it is always possible to use :meth:`~decimal.Context.create_decimal`
++ in order to obtain a rounded or inexact value.
++
++
++* The power function in decimal.py is always correctly-rounded. In the
++ C version, it is defined in terms of the correctly-rounded
++ :meth:`~decimal.Decimal.exp` and :meth:`~decimal.Decimal.ln` functions,
++ but the final result is only "almost always correctly rounded".
++
++
++* In the C version, the context dictionary containing the signals is a
++ :class:`~collections.abc.MutableMapping`. For speed reasons,
++ :attr:`~decimal.Context.flags` and :attr:`~decimal.Context.traps` always
++ refer to the same :class:`~collections.abc.MutableMapping` that the context
++ was initialized with. If a new signal dictionary is assigned,
++ :attr:`~decimal.Context.flags` and :attr:`~decimal.Context.traps`
++ are updated with the new values, but they do not reference the RHS
++ dictionary.
++
++
++* Pickling a :class:`~decimal.Context` produces a different output in order
++ to have a common interchange format for the Python and C versions.
++
++
++* The order of arguments in the :class:`~decimal.Context` constructor has been
++ changed to match the order displayed by :func:`repr`.
++
++
++* The ``watchexp`` parameter in the :meth:`~decimal.Decimal.quantize` method
++ is deprecated.

+-codecs
+-------
+-
+-The :mod:`~encodings.mbcs` codec has been rewritten to handle correctly
+-``replace`` and ``ignore`` error handlers on all Windows versions. The
+-:mod:`~encodings.mbcs` codec now supports all error handlers, instead of only
+-``replace`` to encode and ``ignore`` to decode.
+-
+-A new Windows-only codec has been added: ``cp65001`` (:issue:`13216`). It is the
+-Windows code page 65001 (Windows UTF-8, ``CP_UTF8``). For example, it is used
+-by ``sys.stdout`` if the console output code page is set to cp65001 (e.g., using
+-``chcp 65001`` command).
+-
+-Multibyte CJK decoders now resynchronize faster. They only ignore the first
+-byte of an invalid byte sequence. For example, ``b'\xff\n'.decode('gb2312',
+-'replace')`` now returns a ``\n`` after the replacement character.
+-
+-(:issue:`12016`)
+-
+-Incremental CJK codec encoders are no longer reset at each call to their
+-encode() methods. For example::
+-
+- $ ./python -q
+- >>> import codecs
+- >>> encoder = codecs.getincrementalencoder('hz')('strict')
+- >>> b''.join(encoder.encode(x) for x in '\u52ff\u65bd\u65bc\u4eba\u3002 Bye.')
+- b'~{NpJ)l6HK!#~} Bye.'
+-
+-This example gives ``b'~{Np~}~{J)~}~{l6~}~{HK~}~{!#~} Bye.'`` with older Python
+-versions.

+-decimal
+--------
+-
+-:issue:`7652` - integrate fast native decimal arithmetic.
+- C-module and libmpdec written by Stefan Krah.
+-
+-The new C version of the decimal module integrates the high speed libmpdec
+-library for arbitrary precision correctly-rounded decimal floating point
+-arithmetic. libmpdec conforms to IBM's General Decimal Arithmetic Specification.
+-
+-Performance gains range from 10x for database applications to 100x for
+-numerically intensive applications. These numbers are expected gains
+-for standard precisions used in decimal floating point arithmetic. Since
+-the precision is user configurable, the exact figures may vary. For example,
+-in integer bignum arithmetic the differences can be significantly higher.
+-
+-The following table is meant as an illustration. Benchmarks are available
+-at http://www.bytereef.org/mpdecimal/quickstart.html.
+-
+- +---------+-------------+--------------+-------------+
+- | | decimal.py | _decimal | speedup |
+- +=========+=============+==============+=============+
+- | pi | 42.02s | 0.345s | 120x |
+- +---------+-------------+--------------+-------------+
+- | telco | 172.19s | 5.68s | 30x |
+- +---------+-------------+--------------+-------------+
+- | psycopg | 3.57s | 0.29s | 12x |
+- +---------+-------------+--------------+-------------+
+-
+-Features
+-~~~~~~~~
+-
+-* The :exc:`~decimal.FloatOperation` signal optionally enables stricter
+- semantics for mixing floats and Decimals.
+-
+-* If Python is compiled without threads, the C version automatically
+- disables the expensive thread local context machinery. In this case,
+- the variable :data:`~decimal.HAVE_THREADS` is set to False.
+-
+-API changes
+-~~~~~~~~~~~
+-
+-* The C module has the following context limits, depending on the machine
+- architecture:
+-
+- +-------------------+---------------------+------------------------------+
+- | | 32-bit | 64-bit |
+- +===================+=====================+==============================+
+- | :const:`MAX_PREC` | :const:`425000000` | :const:`999999999999999999` |
+- +-------------------+---------------------+------------------------------+
+- | :const:`MAX_EMAX` | :const:`425000000` | :const:`999999999999999999` |
+- +-------------------+---------------------+------------------------------+
+- | :const:`MIN_EMIN` | :const:`-425000000` | :const:`-999999999999999999` |
+- +-------------------+---------------------+------------------------------+
+-
+-* In the context templates (:class:`~decimal.DefaultContext`,
+- :class:`~decimal.BasicContext` and :class:`~decimal.ExtendedContext`)
+- the magnitude of :attr:`~decimal.Context.Emax` and
+- :attr:`~decimal.Context.Emin` has changed to :const:`999999`.
+-
+-* The :class:`~decimal.Decimal` constructor in decimal.py does not observe
+- the context limits and converts values with arbitrary exponents or precision
+- exactly. Since the C version has internal limits, the following scheme is
+- used: If possible, values are converted exactly, otherwise
+- :exc:`~decimal.InvalidOperation` is raised and the result is NaN. In the
+- latter case it is always possible to use :meth:`~decimal.Context.create_decimal`
+- in order to obtain a rounded or inexact value.
+-
+-
+-* The power function in decimal.py is always correctly-rounded. In the
+- C version, it is defined in terms of the correctly-rounded
+- :meth:`~decimal.Decimal.exp` and :meth:`~decimal.Decimal.ln` functions,
+- but the final result is only "almost always correctly rounded".
+-
+-
+-* In the C version, the context dictionary containing the signals is a
+- :class:`~collections.abc.MutableMapping`. For speed reasons,
+- :attr:`~decimal.Context.flags` and :attr:`~decimal.Context.traps` always
+- refer to the same :class:`~collections.abc.MutableMapping` that the context
+- was initialized with. If a new signal dictionary is assigned,
+- :attr:`~decimal.Context.flags` and :attr:`~decimal.Context.traps`
+- are updated with the new values, but they do not reference the RHS
+- dictionary.
+-
+-
+-* Pickling a :class:`~decimal.Context` produces a different output in order
+- to have a common interchange format for the Python and C versions.
+-
+-
+-* The order of arguments in the :class:`~decimal.Context` constructor has been
+- changed to match the order displayed by :func:`repr`.
+-
+-
+-* The ``watchexp`` parameter in the :meth:`~decimal.Decimal.quantize` method
+- is deprecated.
++Other API Changes
++~~~~~~~~~~~~~~~~~
++
++New :class:`~email.parser.BytesHeaderParser`, added to the :mod:`~email.parser`

++ an email header, convert it into an aware :class:`~datetime.datetime`,
++ or a naive :class:`~datetime.datetime` if the offset is ``-0000``.
++
++ * :func:`~email.utils.localtime`: With no argument, returns the
++ current local time as an aware :class:`~datetime.datetime` using the local
++ :class:`~datetime.timezone`. Given an aware :class:`~datetime.datetime`,

++
++
++What's New in Python 3.2 Release Candidate 3?
++=============================================
++
++*Release date: 13-Feb-2011*
++
++Core and Builtins
++-----------------
++
++- Issue #11134: Add missing fields to typeslots.h.
++
++- Issue #11135: Remove redundant doc field from PyType_Spec.
++
++- Issue #11067: Add PyType_GetFlags, to support PyUnicode_Check in the limited
++ ABI.
++
++- Issue #11118: Fix bogus export of None in python3.dll.
++
++Library
++-------
++
++- Issue #11116: any error during addition of a message to a mailbox now causes a
++ rollback, instead of leaving the mailbox partially modified.
++
++- Issue #11132: Fix passing of "optimize" parameter when recursing in
++ compileall.compile_dir().
++
++- Issue #11110: Fix a potential decref of a NULL in sqlite3.
++
++- Issue #8275: Fix passing of callback arguments with ctypes under Win64. Patch
++ by Stan Mihai.
++
++Build
++-----
++
++- Issue #11079: The /Applications/Python x.x folder created by the Mac OS X
++ installers now includes a link to the installed documentation and no longer
++ includes an Extras directory. The Tools directory is now installed in the
++ framework under share/doc.
++
++- Issue #11121: Fix building with --enable-shared.
++
++Tests
++-----
++
++- Issue #10971: test_zipimport_support is once again compatible with the refleak
++ hunter feature of test.regrtest.
++
++
++What's New in Python 3.2 Release Candidate 2?
++=============================================
++
++*Release date: 30-Jan-2011*
++
++Core and Builtins
++-----------------
++
++- Issue #10451: memoryview objects could allow to mutate a readable buffer.
++ Initial patch by Ross Lagerwall.
++
++Library
++-------
++
++- Issue #9124: mailbox now accepts binary input and reads and writes mailbox
++ files in binary mode, using the email package's binary support to parse
++ arbitrary email messages. StringIO and text file input is deprecated,
++ and string input fails early if non-ASCII characters are used, where
++ previously it would fail when the email was processed in a later step.
++
++- Issue #10845: Mitigate the incompatibility between the multiprocessing
++ module on Windows and the use of package, zipfile or directory execution
++ by special casing main modules that actually *are* called __main__.py.
++
++- Issue #11045: Protect logging call against None argument.
++
++- Issue #11052: Correct IDLE menu accelerators on Mac OS X for Save
++ commands.
++
++- Issue #11053: Fix IDLE "Syntax Error" windows to behave as in 2.x,
++ preventing a confusing hung appearance on OS X with the windows
++ obscured.
++
++- Issue #10940: Workaround an IDLE hang on Mac OS X 10.6 when using the
++ menu accelerators for Open Module, Go to Line, and New Indent Width.
++ The accelerators still work but no longer appear in the menu items.
++
++- Issue #10989: Fix a crash on SSLContext.load_verify_locations(None, True).
++
++- Issue #11020: Command-line pyclbr was broken because of missing 2-to-3
++ conversion.
++
++- Issue #11019: Fixed BytesGenerator so that it correctly handles a Message
++ with a None body.
++
++- Issue #11014: Make 'filter' argument in tarfile.Tarfile.add() into a
++ keyword-only argument. The preceding positional argument was deprecated,
++ so it made no sense to add filter as a positional argument.
++
++- Issue #11004: Repaired edge case in deque.count().
++
++- Issue #10974: IDLE no longer crashes if its recent files list includes files
++ with non-ASCII characters in their path names.
++
++- Have hashlib.algorithms_available and hashlib.algorithms_guaranteed both
++ return sets instead of one returning a tuple and the other a frozenset.
++
++- Issue #10987: Fix the recursion limit handling in the _pickle module.
++
++- Issue #10983: Fix several bugs making tunnel requests in http.client.
++
++- Issue #10955: zipimport uses ASCII encoding instead of cp437 to decode
++ filenames, at bootstrap, if the codec registry is not ready yet. It is still
++ possible to have non-ASCII filenames using the Unicode flag (UTF-8 encoding)
++ for all file entries in the ZIP file.
++
++- Issue #10949: Improved robustness of rotating file handlers.
++
++- Issue #10955: Fix a potential crash when trying to mmap() a file past its
++ length. Initial patch by Ross Lagerwall.
++
++- Issue #10898: Allow compiling the posix module when the C library defines
++ a symbol named FSTAT.
++
++- Issue #10980: the HTTP server now encodes headers with iso-8859-1 (latin1)
++ encoding. This is the preferred encoding of PEP 3333 and the base encoding
++ of HTTP 1.1.
++
++- To match the behaviour of HTTP server, the HTTP client library now also
++ encodes headers with iso-8859-1 (latin1) encoding. It was already doing
++ that for incoming headers which makes this behaviour now consistent in
++ both incoming and outgoing direction.
++
++- Issue #9509: argparse now properly handles IOErrors raised by
++ argparse.FileType.
++
++- Issue #10961: The new pydoc server now better handles exceptions raised
++ during request handling.
++
++- Issue #10680: Fix mutually exclusive arguments for argument groups in
++ argparse.
++
++Build
++-----
++
++- Issue #11054: Allow Mac OS X installer builds to again work on 10.5 with
++ the system-provided Python.
++
++
++What's New in Python 3.2 Release Candidate 1
++============================================
++
++*Release date: 16-Jan-2011*
++
++Core and Builtins
++-----------------
++
++- Issue #10889: range indexing and slicing now works correctly on ranges with
++ a length that exceeds sys.maxsize.
++
++- Issue #10892: Don't segfault when trying to delete __abstractmethods__ from a
++ class.
++
++- Issue #8020: Avoid a crash where the small objects allocator would read
++ non-Python managed memory while it is being modified by another thread. Patch
++ by Matt Bandy.
++
++- Issue #10841: On Windows, set the binary mode on stdin, stdout, stderr and all
++ io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
++ translates newlines (\r\n => \n).
++
++- Remove buffer API from stable ABI for now, see #10181.
++
++- Issue #8651: PyArg_Parse*() functions raise an OverflowError if the file
++ doesn't have PY_SSIZE_T_CLEAN define and the size doesn't fit in an int
++ (length bigger than 2^31-1 bytes).
++
++- Issue #9015, #9611: FileIO.readinto(), FileIO.write(), os.write() and
++ stdprinter.write() clamp the length to INT_MAX on Windows.
++
++- Issue #8278: On Windows and with a NTFS filesystem, os.stat() and os.utime()
++ can now handle dates after 2038.
++
++- Issue #10780: PyErr_SetFromWindowsErrWithFilename() and
++ PyErr_SetExcFromWindowsErrWithFilename() decode the filename from the
++ filesystem encoding instead of UTF-8.
++
++- Issue #10779: PyErr_WarnExplicit() decodes the filename from the filesystem
++ encoding instead of UTF-8.

++
++Library
++-------
++
++- Issue #10916: mmap should not segfault when a file is mapped using 0 as length
++ and a non-zero offset, and an attempt to read past the end of file is made
++ (IndexError is raised instead). Patch by Ross Lagerwall.
++
++- Issue #10154, #10090: change the normalization of UTF-8 to "UTF-8" instead
++ of "UTF8" in the locale module as the latter is not supported MacOSX and OpenBSD.
++
++- Issue #10907: Warn OS X 10.6 IDLE users to use ActiveState Tcl/Tk 8.5, rather
++ than the currently problematic Apple-supplied one, when running with the
++ 64-/32-bit installer variant.
++
++- Issue #4953: cgi.FieldStorage and cgi.parse() parse the request as bytes, not
++ as unicode, and accept binary files. Add encoding and errors attributes to
++ cgi.FieldStorage. Patch written by Pierre Quentel (with many inputs by Glenn
++ Linderman).
++
++- Add encoding and errors arguments to urllib.parse_qs() and urllib.parse_qsl().
++
++- Issue #10899: No function type annotations in the standard library. Removed

++ if available.
++
++- Issue #10869: Fixed bug where ast.increment_lineno modified the root node
++ twice.
++
++- Issue #5871: email.header.Header.encode now raises an error if any
++ continuation line in the formatted value has no leading white space and looks
++ like a header. Since Generator uses Header to format all headers, this check
++ is made for all headers in any serialized message at serialization time. This
++ provides protection against header injection attacks.
++
++- Issue #10859: Make ``contextlib.GeneratorContextManager`` officially
++ private by renaming it to ``_GeneratorContextManager``.
++
++- Issue #10042: Fixed the total_ordering decorator to handle cross-type
++ comparisons that could lead to infinite recursion.
++
++- Issue #10686: the email package now :rfc:`2047`\ -encodes headers with
++ non-ASCII bytes (parsed by a BytesParser) when doing conversion to 7bit-clean
++ presentation, instead of replacing them with ?s.
++
++- email.header.Header was incorrectly encoding folding whitespace when
++ rfc2047-encoding header values with embedded newlines, leaving them without
++ folding whitespace. It now uses the continuation_ws, as it does for
++ continuation lines that it creates itself.
++
++- Issue #1777412, #10827: Changed the rules for 2-digit years. The
++ time.asctime(), time.ctime() and time.strftime() functions will now format
++ any year when ``time.accept2dyear`` is False and will accept years >= 1000
++ otherwise. ``time.mktime`` and ``time.strftime`` now accept full range
++ supported by the OS. With Visual Studio or on Solaris, the year is limited to
++ the range [1; 9999]. Conversion of 2-digit years to 4-digit is deprecated.
++
++- Issue #7858: Raise an error properly when os.utime() fails under Windows
++ on an existing file.
++
++- Issue #3839: wsgiref should not override a Content-Length header set by
++ the application. Initial patch by Clovis Fabricio.
++
++- Issue #10492: bdb.Bdb.run() only traces the execution of the code, not the
++ compilation (if the input is a string).
++
++- Issue #7995: When calling accept() on a socket with a timeout, the returned
++ socket is now always blocking, regardless of the operating system.
++
++- Issue #10756: atexit normalizes the exception before displaying it. Patch by
++ Andreas Stührk.
++
++- Issue #10790: email.header.Header.append's charset logic now works correctly
++ for charsets whose output codec is different from its input codec.
++
++- Issue #10819: SocketIO.name property returns -1 when its closed, instead of
++ raising a ValueError, to fix repr().
++
++- Issue #8650: zlib.compress() and zlib.decompress() raise an OverflowError if
++ the input buffer length doesn't fit into an unsigned int (length bigger than
++ 2^32-1 bytes).
++
++- Issue #6643: Reinitialize locks held within the threading module after fork to
++ avoid a potential rare deadlock or crash on some platforms.
++
++- Issue #10806, issue #9905: Fix subprocess pipes when some of the standard file
++ descriptors (0, 1, 2) are closed in the parent process. Initial patch by Ross
++ Lagerwall.
++
++- `unittest.TestCase` can be instantiated without a method name; for simpler
++ exploration from the interactive interpreter.
++
++- Issue #10798: Reject supporting concurrent.futures if the system has too
++ few POSIX semaphores.
++
++- Issue #10807: Remove base64, bz2, hex, quopri, rot13, uu and zlib codecs from
++ the codec aliases. They are still accessible via codecs.lookup().
++
++- Issue #10801: In zipfile, support different encodings for the header and the
++ filenames.
++
++- Issue #6285: IDLE no longer crashes on missing help file; patch by Scott
++ David Daniels.
++
++- Fix collections.OrderedDict.setdefault() so that it works in subclasses that
++ define __missing__().
++
++- Issue #10786: unittest.TextTestRunner default stream no longer bound at import
++ time. `sys.stderr` now looked up at instantiation time. Fix contributed by
++ Mark Roddy.
++
++- Issue #10753: Characters ';', '=' and ',' in the PATH_INFO environment variable
++ won't be quoted when the URI is constructed by the wsgiref.util's request_uri
++ method. According to RFC 3986, these characters can be a part of params in
++ PATH component of URI and need not be quoted.
++
++- Issue #10738: Fix webbrowser.Opera.raise_opts.
++
++- Issue #9824: SimpleCookie now encodes , and ; in values to cater to how
++ browsers actually parse cookies.
++
++- Issue #9333: os.symlink now available regardless of user privileges. The
++ function now raises OSError on Windows >=6.0 when the user is unable to create
++ symbolic links. XP and 2003 still raise NotImplementedError.
++
++- Issue #10783: struct.pack() no longer implicitly encodes unicode to UTF-8.
++
++- Issue #10730: Add SVG mime types to mimetypes module.
++
++- Issue #10768: Make the Tkinter ScrolledText widget work again.

++ ElementTree register_namespace().
++
++- Issue #10626: test_logging now preserves logger disabled states.
++
++- Issue #10774: test_logging now removes temp files created during tests.
++
++- Issue #5258/#10642: if site.py encounters a .pth file that generates an error,
++ it now prints the filename, line number, and traceback to stderr and skips
++ the rest of that individual file, instead of stopping processing entirely.
++
++- Issue #10763: subprocess.communicate() closes stdout and stderr if both are
++ pipes (bug specific to Windows).
++
++- Issue #1693546: fix email.message RFC 2231 parameter encoding to be in better
++ compliance (no "s around encoded values).
++
++- Improved the diff message in the unittest module's assertCountEqual().
++
++- Issue #1155362: email.utils.parsedate_tz now handles a missing space before
++ the '-' of a timezone field as well as before a '+'.
++
++- Issue #4871: The zipfile module now gives a more useful error message if
++ an attempt is made to use a string to specify the archive password.
++
++- Issue #10750: The ``raw`` attribute of buffered IO objects is now read-only.
++
++- Deprecated assertDictContainsSubset() in the unittest module.
++
++C-API
++-----
++
++- PyObject_CallMethod now passes along any underlying AttributeError from
++ PyObject_GetAttr, instead of replacing it with something less informative
++
++- Issue #10913: Deprecate misleading functions PyEval_AcquireLock() and
++ PyEval_ReleaseLock(). The thread-state aware APIs should be used instead.
++
++- Issue #10333: Remove ancient GC API, which has been deprecated since Python
++ 2.2.
++
++Build
++-----
++
++- Issue #10843: Update third-party library versions used in OS X 32-bit
++ installer builds: bzip2 1.0.6, readline 6.1.2, SQLite 3.7.4 (with FTS3/FTS4
++ and RTREE enabled), and ncursesw 5.5 (wide-char support enabled).
++
++- Issue #10820: Fix OS X framework installs to support version-specific
++ scripts (#10679).
++
++- Issue #7716: Under Solaris, don't assume existence of /usr/xpg4/bin/grep in
++ the configure script but use $GREP instead. Patch by Fabian Groffen.
++
++- Issue #10475: Don't hardcode compilers for LDSHARED/LDCXXSHARED on NetBSD
++ and DragonFly BSD. Patch by Nicolas Joly.
++
++- Issue #10679: The "idle", "pydoc" and "2to3" scripts are now installed with
++ a version-specific suffix on "make altinstall".
++
++- Issue #10655: Fix the build on PowerPC on Linux with GCC when building with
++ timestamp profiling (--with-tsc): the preprocessor test for the PowerPC
++ support now looks for "__powerpc__" as well as "__ppc__": the latter seems to
++ only be present on OS X; the former is the correct one for Linux with GCC.
++
++- Issue #1099: Fix the build on MacOSX when building a framework with pydebug
++ using GCC 4.0.
++
++Tools/Demos

++
++What's New in Python 3.2 Alpha 4?
++=================================
++
++*Release date: 13-Nov-2010*
++
++Core and Builtins
++-----------------
++
++- Issue #10372: Import the warnings module only after the IO library is
++ initialized, so as to avoid bootstrap issues with the '-W' option.
++
++- Issue #10293: Remove obsolete field in the PyMemoryView structure, unused
++ undocumented value PyBUF_SHADOW, and strangely-looking code in
++ PyMemoryView_GetContiguous.
++
++- Issue #6081: Add str.format_map(), similar to ``str.format(**mapping)``.
++
++- If FileIO.__init__ fails, close the file descriptor.
++
++- Issue #10221: dict.pop(k) now has a key error message that includes the
++ missing key (same message d[k] returns for missing keys).
++
++- Issue #5437: A preallocated MemoryError instance should not keep traceback
++ data (including local variables caught in the stack trace) alive infinitely.
++
++- Issue #10186: Fix the SyntaxError caret when the offset is equal to the length
++ of the offending line.
++
++- Issue #10089: Add support for arbitrary -X options on the command line. They
++ can be retrieved through a new attribute ``sys._xoptions``.
++
++- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
++ the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
++ variable is not set, the locale encoding is ISO-8859-1, whereas most programs
++ (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
++ encoding and to encode command line arguments on this OS.
++
++- Issue #9713, #10114: Parser functions (e.g. PyParser_ASTFromFile) expect
++ filenames encoded to the filesystem encoding with the surrogateescape error
++ handler (to support undecodable bytes), instead of UTF-8 in strict mode.
++
++- Issue #9997: Don't let the name "top" have special significance in scope
++ resolution.
++
++- Issue #9862: Compensate for broken PIPE_BUF in AIX by hard coding its value as
++ the default 512 when compiling on AIX.
++
++- Use locale encoding instead of UTF-8 to encode and decode filenames if
++ Py_FileSystemDefaultEncoding is not set.
++
++- Issue #10095: fp_setreadl() doesn't reopen the file, instead reuse the file
++ descriptor.
++
++- Issue #9418: Moved private string methods ``_formatter_parser`` and
++ ``_formatter_field_name_split`` into a new ``_string`` module.
++
++- Issue #9992: Remove PYTHONFSENCODING environment variable.
++
++Library
++-------
++
++- Issue #12943: python -m tokenize support has been added to tokenize.
++
++- Issue #10465: fix broken delegating of attributes by gzip._PaddedFile.
++
++- Issue #10356: Decimal.__hash__(-1) should return -2.
++
++- Issue #1553375: logging: Added stack_info kwarg to display stack information.
++
++- Issue #5111: IPv6 Host in the Header is wrapped inside [ ]. Patch by Chandru.
++
++- Fix Fraction.__hash__ so that Fraction.__hash__(-1) is -2. (See also issue
++ #10356.)
++
++- Issue #4471: Add the IMAP.starttls() method to enable encryption on standard
++ IMAP4 connections. Original patch by Lorenzo M. Catucci.
++
++- Issue #1466065: Add 'validate' option to base64.b64decode to raise an error if
++ there are non-base64 alphabet characters in the input.
++
++- Issue #10386: Add __all__ to token module; this simplifies importing in
++ tokenize module and prevents leaking of private names through ``import *``.
++
++- Issue #4471: Properly shutdown socket in IMAP.shutdown(). Patch by Lorenzo
++ M. Catucci.
++
++- Fix IMAP.login() to work properly.
++
++- Issue #9244: multiprocessing pool worker processes could terminate
++ unexpectedly if the return value of a task could not be pickled. Only the
++ ``repr`` of such errors are now sent back, wrapped in an
++ ``MaybeEncodingError`` exception.
++
++- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of
++ ``multiprocessing.Pool`` now accepts a ``error_callback`` argument. This can
++ be a callback with the signature ``callback(exc)``, which will be called if
++ the target raises an exception.
++
++- Issue #10022: The dictionary returned by the ``getpeercert()`` method of SSL
++ sockets now has additional items such as ``issuer`` and ``notBefore``.
++
++- ``usenetrc`` is now false by default for NNTP objects.
++
++- Issue #1926: Add support for NNTP over SSL on port 563, as well as STARTTLS.
++ Patch by Andrew Vant.
++
++- Issue #10335: Add tokenize.open(), detect the file encoding using
++ tokenize.detect_encoding() and open it in read only mode.
++
++- Issue #10321: Add support for binary data to smtplib.SMTP.sendmail, and a new
++ method send_message to send an email.message.Message object.
++
++- Issue #6011: sysconfig and distutils.sysconfig use the surrogateescape error
++ handler to parse the Makefile file. Avoid a UnicodeDecodeError if the source
++ code directory name contains a non-ASCII character and the locale encoding is
++ ASCII.
++
++- Issue #10329: The trace module writes reports using the input Python script
++ encoding, instead of the locale encoding. Patch written by Alexander
++ Belopolsky.
++
++- Issue #10126: Fix distutils' test_build when Python was built with
++ --enable-shared.
++
++- Issue #9281: Prevent race condition with mkdir in distutils. Patch by
++ Arfrever.
++
++- Issue #10229: Fix caching error in gettext.
++
++- Issue #10252: Close file objects in a timely manner in distutils code and
++ tests. Patch by Brian Brazil, completed by Éric Araujo.

++ unpickling them produced nonsensical results.
++
++- Issue #10311: The signal module now restores errno before returning from its
++ low-level signal handler. Patch by Hallvard B Furuseth.
++
++- Issue #10282: Add a ``nntp_implementation`` attribute to NNTP objects.
++
++- Issue #10283: Add a ``group_pattern`` argument to NNTP.list().
++
++- Issue #10155: Add IISCGIHandler to wsgiref.handlers to support IIS CGI
++ environment better, and to correct unicode environment values for WSGI 1.0.1.
++
++- Issue #10281: nntplib now returns None for absent fields in the OVER/XOVER
++ response, instead of raising an exception.
++
++- wsgiref now implements and validates PEP 3333, rather than an experimental
++ extension of PEP 333. (Note: earlier versions of Python 3.x may have
++ incorrectly validated some non-compliant applications as WSGI compliant; if
++ your app validates with Python <3.2b1+, but not on this version, it is likely
++ the case that your app was not compliant.)
++
++- Issue #10280: NNTP.nntp_version should reflect the highest version advertised
++ by the server.
++
++- Issue #10184: Touch directories only once when extracting a tarfile.
++
++- Issue #10199: New package, ``turtledemo`` now contains selected demo scripts
++ that were formerly found under Demo/turtle.
++
++- Issue #10265: Close file objects explicitly in sunau. Patch by Brian Brazil.
++
++- Issue #10266: uu.decode didn't close in_file explicitly when it was given as a
++ filename. Patch by Brian Brazil.

++ parameter had been reduced.
++
++- Issue #10160: Speed up operator.attrgetter. Patch by Christos Georgiou.

++ pretty-printing multilevel objects.
++
++- Issue #10253: FileIO leaks a file descriptor when trying to open a file for
++ append that isn't seekable. Patch by Brian Brazil.
++
++- Support context manager protocol for file-like objects returned by mailbox
++ ``get_file()`` methods.
++
++- Issue #10246: uu.encode didn't close file objects explicitly when filenames
++ were given to it. Patch by Brian Brazil.
++
++- Issue #10198: fix duplicate header written to wave files when writeframes() is
++ called without data.
++
++- Close file objects in modulefinder in a timely manner.
++
++- Close a io.TextIOWrapper object in email.parser in a timely manner.
++
++- Close a file object in distutils.sysconfig in a timely manner.
++
++- Close a file object in pkgutil in a timely manner.
++
++- Issue #10233: Close file objects in a timely manner in the tarfile module and
++ its test suite.
++
++- Issue #10093: ResourceWarnings are now issued when files and sockets are
++ deallocated without explicit closing. These warnings are silenced by default,
++ except in pydebug mode.
++
++- tarfile.py: Add support for all missing variants of the GNU sparse extensions
++ and create files with holes when extracting sparse members.
++
++- Issue #10218: Return timeout status from ``Condition.wait`` in threading.
++
++- Issue #7351: Add ``zipfile.BadZipFile`` spelling of the exception name and
++ deprecate the old name ``zipfile.BadZipfile``.
++
++- Issue #5027: The standard ``xml`` namespace is now understood by
++ xml.sax.saxutils.XMLGenerator as being bound to
++ http://www.w3.org/XML/1998/namespace. Patch by Troy J. Farrell.
++
++- Issue #5975: Add csv.unix_dialect class.
++
++- Issue #7761: telnetlib.interact failures on Windows fixed.
++
++- logging: Added style option to Formatter to allow %, {} or $-formatting.
++
++- Issue #5178: Added tempfile.TemporaryDirectory class that can be used as a
++ context manager.
++
++- Issue #1349106: Generator (and BytesGenerator) flatten method and Header
++ encode method now support a 'linesep' argument.
++
++- Issue #5639: Add a *server_hostname* argument to ``SSLContext.wrap_socket`` in
++ order to support the TLS SNI extension. ``HTTPSConnection`` and ``urlopen()``
++ also use this argument, so that HTTPS virtual hosts are now supported.
++
++- Issue #10166: Avoid recursion in pstats Stats.add() for many stats items.
++
++- Issue #10163: Skip unreadable registry keys during mimetypes initialization.
++

++ ntpath.)
++
++- Issue #1343: xml.sax.saxutils.XMLGenerator now has an option
++ short_empty_elements to direct it to use self-closing tags when appropriate.
++
++- Issue #9807 (part 1): Expose the ABI flags in sys.abiflags. Add --abiflags
++ switch to python-config for command line access.
++
++- Issue #6098: Don't claim DOM level 3 conformance in minidom.
++
++- Issue #5762: Fix AttributeError raised by ``xml.dom.minidom`` when an empty
++ XML namespace attribute is encountered.
++
++- Issue #2830: Add the ``html.escape()`` function, which quotes all problematic
++ characters by default. Deprecate ``cgi.escape()``.

++ supported by the system. Patch by Nikita Vetoshkin.
++
++- Issue #10063: file:// scheme will stop accessing remote hosts via ftp

++ not correct, change is made to raise a URLError when a remote host is tried to
++ access via file:// scheme.
++
++- Issue #1710703: Write structures for an empty ZIP archive when a ZipFile is
++ created in modes 'a' or 'w' and then closed without adding any files. Raise
++ BadZipfile (rather than IOError) when opening small non-ZIP files.
++
++- Issue #10041: The signature of optional arguments in socket.makefile() didn't
++ match that of io.open(), and they also didn't get forwarded properly to

++
++What's New in Python 3.2 Alpha 3?
++=================================
++
++*Release date: 09-Oct-2010*
++
++Core and Builtins
++-----------------
++
++- Issue #10068: Global objects which have reference cycles with their module's
++ dict are now cleared again. This causes issue #7140 to appear again.
++
++- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
++ encodings.
++
++- ast.literal_eval() can now handle negative numbers. It is also a little more
++ liberal in what it accepts without compromising the safety of the evaluation.
++ For example, 3j+4 and 3+4+5 are both accepted.
++
++- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
++ result metaclasses can now be ABCs (see #9533).
++
++- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
++
++- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
++ UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
++ 32 bits wchar_t (eg. Linux in narrow build).
++
++- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
++ introduced by issue #9324.
++
++- Issue #9979: Create function PyUnicode_AsWideCharString().
++
++- Issue #7397: Mention that importlib.import_module() is probably what someone
++ really wants to be using in __import__'s docstring.
++
++- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
++ to use named arguments.
++
++- Issue #9930: Remove bogus subtype check that was causing (e.g.)
++ float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
++
++- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
++
++- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
++ threads are still running. Instead, reinitialize the GIL on a second call to
++ Py_Initialize().
++
++- All SyntaxErrors now have a column offset and therefore a caret when the error
++ is printed.
++
++- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
++ module that was imported, but instead gets the module from sys.modules.
++
++- Issue #9213: The range type_items now provides index() and count() methods, to
++ conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
++
++- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
++ with a non-empty format string. This is an effort to future-proof user
++ code. If a derived class does not currently implement __format__ but later
++ adds its own __format__, it would most likely break user code that had
++ supplied a format string. This will be changed to a DeprecationWaring in
++ Python 3.3 and it will be an error in Python 3.4.
++
++- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
++ re-created on a subsequent call to Py_Initialize(). The problem (a crash)
++ wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
++
++- Issue #9210: Configure option --with-wctype-functions was removed. Using the
++ functions from the libc caused the methods .upper() and lower() to become
++ locale aware and created subtly wrong results.
++
++- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
++ non-ASCII byte in the format string.
++
++- Issue #4617: Previously it was illegal to delete a name from the local
++ namespace if it occurs as a free variable in a nested block. This limitation
++ of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
++
++- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
++ ``\UXXXXXXXX``, regardless of whether the character is printable or not.
++ Also, the "backslashreplace" error handler now joins surrogate pairs into a
++ single character on UCS-2 builds.
++
++- Issue #9757: memoryview objects get a release() method to release the
++ underlying buffer (previously this was only done when deallocating the
++ memoryview), and gain support for the context management protocol.
++
++- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
++ thread-local storage key.
++
++Library
++-------
++
++- Issue #2236: distutils' mkpath ignored the mode parameter.
++
++- Fix typo in one sdist option (medata-check).
++
++- Issue #9199: Fix incorrect use of distutils.cmd.Command.announce.
++
++- Issue #1718574: Fix options that were supposed to accept arguments but did
++ not in build_clib.
++
++- Issue #9437: Fix building C extensions with non-default LDFLAGS.
++
++- Issue #4661: email can now parse bytes input and generate either converted
++ 7bit output or bytes output. Email version bumped to 5.1.0.
++
++- Issue #1589: Add ssl.match_hostname(), to help implement server identity
++ verification for higher-level protocols.
++
++- Issue #9759: GzipFile now raises ValueError when an operation is attempted
++ after the file is closed. Patch by Jeffrey Finkelstein.
++
++- Issue #9042: Fix interaction of custom translation classes and caching in
++ gettext.
++
++- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
++ returning a (sock, addr) pair which is called when a connection has been
++ established with a new remote endpoint. This is supposed to be used as a
++ replacement for old handle_accept() and avoids the user to call accept()
++ directly.
++
++- Issue #9065: tarfile no longer uses "root" as the default for the uname and
++ gname field.
++
++- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
++ an environment that does not have docutils. Patch by Arfrever.
++
++- Issue #1050268: parseaddr now correctly quotes double quote and backslash
++ characters that appear inside quoted strings in email addresses.
++
++- Issue #10004: quoprimime no longer generates a traceback when confronted with
++ invalid characters after '=' in a Q-encoded word.
++
++- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
++ sending a 200 OK for the Expect: 100-continue request header.
++
++- Issue #9360: Cleanup and improvements to the nntplib module. The API now
++ conforms to the philosophy of bytes and unicode separation in Python 3. A
++ test suite has also been added.
++
++- Issue #9962: GzipFile now has the peek() method.
++
++- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
++ retry the select() loop instead of bailing out. This is because select() can
++ incorrectly report a socket as ready for reading (for example, if it received
++ some data with an invalid checksum).
++
++- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
++
++- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
++ received. Now sendall() properly calls signal handlers if necessary, and
++ retries sending if these returned successfully, including on sockets with a
++ timeout.
++
++- Issue #9947: logging: Fixed locking bug in stopListening.
++
++- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
++
++- Issue #9936: Fixed executable lines' search in the trace module.
++
++- Issue #9790: Rework imports necessary for samefile and sameopenfile
++ in ntpath.
++
++- Issue #9928: Properly initialize the types exported by the bz2 module.
++
++- Issue #1675951: Allow GzipFile to work with unseekable file objects. Patch by
++ Florian Festi.
++
++- Logging: Added QueueListener class to facilitate logging usage for
++ performance-critical threads.
++
++- Issue #9916: Add some missing errno symbols.
++
++- Issue #9877: Expose sysconfig.get_makefile_filename()
++
++- logging: Added hasHandlers() method to Logger and LoggerAdapter.
++
++- Issue #9908: Fix os.stat() on bytes paths under Windows 7.
++
++- Issue #2643: msync() is not called anymore when deallocating an open mmap
++ object, only munmap().
++
++- logging: Changed LoggerAdapter implementation internally, to make it easier to
++ subclass in a useful way.
++
++- logging: hasHandlers method was added to Logger, and isEnabledFor,
++ getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
++ LoggerAdapter was introduced into the unit tests for logging.
++
++- Issue #1686: Fix string.Template when overriding the pattern attribute.
++
++- Issue #9854: SocketIO objects now observe the RawIOBase interface in
++ non-blocking mode: they return None when an operation would block (instead of
++ raising an exception).
++
++- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
++ another kind.
++
++- Issue #9441: logging has better coverage for rotating file handlers.
++
++- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
++
++- Issue #9854: The default read() implementation in io.RawIOBase now handles
++ non-blocking readinto() returning None correctly.
++
++- Issue #1552: socket.socketpair() now returns regular socket.socket objects
++ supporting the whole socket API (rather than the "raw" _socket.socket
++ objects).
++
++- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
++ to match the corresponding socket methods.
++
++- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
++ them handle recursive calls within the same thread.
++
++- logging: Enhanced HTTPHandler with secure and credentials initializers.
++
++- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
++
++- Issue #9837: The read() method of ZipExtFile objects (as returned by
++ ZipFile.open()) could return more bytes than requested.
++
++- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
++ d['x'] = d.
++
++- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
++ it possible for the user to create self-referencing ordered dictionaries which
++ become permanently uncollectable GC garbage. Reinstated the Python 3.1
++ approach of using weakref proxies so that reference cycles never get created
++ in the first place.
++
++- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
++ encode the value with filesystem encoding and surrogateescape (instead of
++ utf-8 in strict mode) . Patch written by David Watson.
++
++- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
++ environment variable to set the filesystem encoding at Python startup.
++ sys.setfilesystemencoding() creates inconsistencies because it is unable to
++ reencode all filenames in all objects.
++
++- Issue #9410: Various optimizations to the pickle module, leading to speedups
++ up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
++ initial patch by Alexandre Vassalotti.
++
++- The pprint module now supports printing OrderedDicts in their given order
++ (formerly, it would sort the keys).
++
++- Logging: Added QueueHandler class to facilitate logging usage with
++ multiprocessing.
++
++- Issue #9707: Rewritten reference implementation of threading.local which is
++ friendlier towards reference cycles. This change is not normally visible
++ since an optimized C implementation (_thread._local) is used instead.
++
++- Issue #6394: os.getppid() is now supported on Windows. Note that it will
++ still return the id of the parent process after it has exited. This process
++ id may even have been reused by another unrelated process.
++
++- Issue #9792: In case of connection failure, socket.create_connection() would
++ swallow the exception and raise a new one, making it impossible to fetch the
++ original errno, or to filter timeout errors. Now the original error is
++ re-raised.
++
++- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
++ the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
++ back after the system call. Original patch by Brian Brazil.
++
++- Updates to the random module:
++
++ * Document which parts of the module are guaranteed to stay the same across
++ versions and which parts are subject to change.
++
++ * Update the seed() method to use all of the bits in a string instead of just
++ the hash value. This makes better use of the seed value and assures the
++ seeding is platform independent. Issue #7889.
++
++ * Improved the random()-->integer algorithm used in choice(), shuffle(),
++ sample(), randrange(), and randint(). Formerly, it used int(n*random())
++ which has a slight bias whenever n is not a power of two. Issue #9025.
++
++ * Improved documentation of arguments to randrange(). Issue #9379.
++
++- collections.OrderedDict now supports a new method for repositioning keys to
++ either end.
++
++- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
++ cases now also have assertWarns and assertWarnsRegexp methods to check that a
++ given warning type was triggered by the code under test.
++
++- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
++ their contents without duplicating them. The view is both readable and
++ writable.
++
++- Issue #7566: Implement os.path.sameopenfile for Windows.
++
++- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
++ unsupported operation is attempted (for example, writing to a file open only
++ for reading).
++
++- hashlib has two new constant attributes: algorithms_guaranteed and
++ algorithms_avaiable that respectively list the names of hash algorithms
++ guaranteed to exist in all Python implementations and the names of hash
++ algorithms available in the current process.
++
++- A new package ``concurrent.futures`` as defined by PEP 3148.
++
++C-API
++-----
++
++- Add PyErr_SyntaxLocationEx, which supports passing a column offset.
++
++- Issue #9834: Don't segfault in PySequence_GetSlice, PySequence_SetSlice, or
++ PySequence_DelSlice when the object doesn't have any mapping operations
++ defined.
++
++Tools/Demos
++-----------
++
++- Issue #9188: The gdb extension now handles correctly narrow (UCS2) as well as
++ wide (UCS4) unicode builds for both the host interpreter (embedded inside gdb)
++ and the interpreter under test.
++
++Tests
++-----
++
++- Issue #9308: Added tests for importing encoded modules that do not
++ depend on specific stdlib modules being encoded in a certain way.
++
++- Issue #1051: Add a script (Lib/test/make_ssl_certs.py) to generate the custom
++ certificate and private key files used by SSL-related certs.
++
++- Issue #9978: Wait until subprocess completes initialization. (Win32KillTests
++ in test_os)
++
++- Issue #7110: regrtest now sends test failure reports and single-failure
++ tracebacks to stderr rather than stdout.
++
++- Issue #9628: fix runtests.sh -x option so more than one test can be excluded.
++
++- Issue #9899: Fix test_tkinter.test_font on various platforms. Patch by Ned
++ Deily.
++
++- Issue #9894: Do not hardcode ENOENT in test_subprocess.
++
++- Issue #9315: Added tests for the trace module. Patch by Eli Bendersky.
++
++- Issue #9323: Make test.regrtest.__file__ absolute, this was not always the
++ case when running profile or trace, for example.
++
++- Issue #9568: Fix test_urllib2_localnet on OS X 10.3.
++
++Build
++-----
++
++- Issue #10062: Allow building on platforms which do not have sem_timedwait.
++
++- Issue #10054: Some platforms provide uintptr_t in inttypes.h. Patch by Akira
++ Kitada.
++
++- Issue #10055: Make json C89-compliant in UCS4 mode.
++
++- Issue #9552: Avoid unnecessary rebuild of OpenSSL. (Windows)
++
++- Issue #1633863: Don't ignore $CC under AIX.
++
++- Issue #9810: Compile bzip2 source files in Python's project file directly. It
++ used to be built with bzip2's makefile.
++
++- Issue #9848: Stopping trying to build _weakref in setup.py as it is a built-in
++ module.
++
++- Issue #9806: python-config now has an ``--extension-suffix`` option that
++ outputs the suffix for dynamic libraries including the ABI version name
++ defined by PEP 3149.
++
++- Issue #941346: Improve the build process under AIX and allow Python to be
++ built as a shared library. Patch by Sébastien Sablé.
++
++- Issue #4026: Make the fcntl extension build under AIX. Patch by Sébastien
++ Sablé.
++
++- Issue #9701: The MacOSX installer can patch the shell profile to ensure that
++ the "bin" directory inside the framework is on the shell's search path. This
++ feature now also supports the ZSH shell.
++
++
++What's New in Python 3.2 Alpha 2?
++=================================
++
++*Release date: 05-Sep-2010*
++
++Core and Builtins
++-----------------
++
++- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
++ the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
++ bytecode is a bit simplified. Patch by Demur Rumed.
++
++- Issue #9766: Rename poorly named variables exposed by _warnings to prevent
++ confusion with the proper variables names from 'warnings' itself.
++
++- Issue #9212: dict_keys and dict_items now provide the isdisjoint() method, to
++ conform to the Set ABC. Patch by Daniel Urban.
++
++- Issue #9737: Fix a crash when trying to delete a slice or an item from a
++ memoryview object.
++
++- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
++ now removed, since their effect was inexistent in 3.x (the default encoding is
++ hardcoded to utf-8 and cannot be changed).
++
++- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
++ properly. Patch by Stefan Behnel.
++
++- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
++ platforms. Previously, it inlined only when using Microsoft Visual C.
++
++- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
++
++- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
++
++- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
++ the pyconfig.h generated by configure on other systems.
++
++- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that
++ occur during attribute lookup are now propagated to the caller.
++
++- Issue #8622: Add PYTHONFSENCODING environment variable to override the
++ filesystem encoding.
++
++- Issue #5127: The C functions that access the Unicode Database now accept and
++ return characters from the full Unicode range, even on narrow unicode builds
++ (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
++ in Python is that unicodedata.numeric() now returns the correct value for
++ large code points, and repr() may consider more characters as printable.
++
++- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
++ as a unicode object, instead of a byte string. Function needed to support
++ unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
++ function.
++
++- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().
++
++- Issue #9612: The set object is now 64-bit clean under Windows.
++
++- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
++ the module file to be executed with the -m command line option.
++
++- Issue #9599: Create PySys_FormatStdout() and PySys_FormatStderr() functions to
++ write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
++ sys.stderr.
++
++- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
++ decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
++ objects are output as-is.
++
++- Issue #9203: Computed gotos are now enabled by default on supported compilers
++ (which are detected by the configure script). They can still be disable
++ selectively by specifying --without-computed-gotos.
++
++- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
++ use PyUnicode_FromFormatV() to format the warning message.
++
++- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
++ array.
++
++- Issue #5319: Print an error if flushing stdout fails at interpreter shutdown.
++
++- Issue #9337: The str() of a float or complex number is now identical to its
++ repr().
++
++- Issue #9416: Fix some issues with complex formatting where the output with no
++ type specifier failed to match the str output:
++
++ - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
++ - format(complex(0.0, 2.0), '-') included a sign and parentheses.
++
++Extension Modules
++-----------------
++
++- Issue #8013: time.asctime and time.ctime no longer call system
++ asctime and ctime functions. The year range for time.asctime is now
++ 1900 through maxint. The range for time.ctime is the same as for
++ time.localtime. The string produced by these functions is longer
++ than 24 characters when year is greater than 9999.
++
++- Issue #6608: time.asctime is now checking struct tm fields its input
++ before passing it to the system asctime. Patch by MunSic Jeong.

++- Issue #4835: make PyLong_FromSocket_t() and PyLong_AsSocket_t() private to the
++ socket module, and fix the width of socket descriptors to be correctly
++ detected under 64-bit Windows.
++
++- Issue #1027206: Support IDNA in gethostbyname, gethostbyname_ex, getaddrinfo
++ and gethostbyaddr. getnameinfo is now restricted to numeric addresses as

++ correctly return a set. Patch by Eli Bendersky.
++
++- Issue #5737: Add Solaris-specific mnemonics in the errno module. Patch by

++ a tuple subclass.
++
++- Issue #9324: Add parameter validation to signal.signal on Windows in order to
++ prevent crashes.

++ module from working correctly with arrays of more than 2**31 elements.
++
++- Fix memory leak in ssl._ssl._test_decode_cert.
++
++- Issue #8065: Fix memory leak in readline module (from failure to free the

++- Issue #808164: Fixed socket.close to avoid references to globals, to avoid
++ issues when socket.close is called from a __del__ method.
++
++- Issue #9706: ssl module provides a better error handling in various
++ circumstances.
++
++- Issue #1868: Eliminate subtle timing issues in thread-local objects by getting
++ rid of the cached copy of thread-local attribute dictionary.

++
++- Issue #8750: Fixed MutableSet's methods to correctly handle reflexive

++
++- Issue #9617: Signals received during a low-level write operation aren't
++ ignored by the buffered IO layer anymore.
++
++- Issue #843590: Make "macintosh" an alias to the "mac_roman" encoding.
++
++- Create os.fsdecode(): decode from the filesystem encoding with surrogateescape
++ error handler, or strict error handler on Windows.

++- Issue #3488: Provide convenient shorthand functions ``gzip.compress`` and
++ ``gzip.decompress``. Original patch by Anand B. Pillai.
++
++- Issue #8807: poplib.POP3_SSL class now accepts a context parameter, which is a

++
++- Issue #8866: parameters passed to socket.getaddrinfo can now be specified as
++ single keyword arguments.
++
++- Address XXX comment in dis.py by having inspect.py prefer to reuse the dis.py

++
++What's New in Python 3.2 Alpha 1?
++=================================
++
++*Release date: 01-Aug-2010*
++
++Core and Builtins
++-----------------
++
++- Issue #8991: convertbuffer() rejects discontigious buffers.
++
++- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
++ compiler.
++
++- Issue #8413: structsequence now subclasses tuple.
++
++- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
++ start byte and the continuation byte(s) are now considered invalid, instead of
++ the number of bytes specified by the start byte. E.g.:
++ '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
++ with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
++ even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
++ returned a single u'\ufffd'.
++
++- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
++ rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
++
++- Be more specific in error messages about positional arguments.
++
++- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
++ objects, as described in the documentation.

++- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
++ Fix the encoding of the modules filename. Patch written by Amaury Forgeot
++ d'Arc.
++
++- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
++ dealing with unary minus applied to a constant. The removed code was mutating
++ the ST, causing a second compilation to fail.
++
++- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
++ mode raises unicode errors. The encoder only supports "strict" and "replace"
++ error handlers, the decoder only supports "strict" and "ignore" error
++ handlers. Patch written by Mark Hammond.
++
++- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
++ "w*" format instead. Add tests for "w*" format.
++
++- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
++ formats if the string contains a null byte/character. Write unit tests for
++ string formats.
++
++- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
++ suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
++ location of the raised exception.
++
++- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
++ filenames and enable os.fsencode().
++
++- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
++
++- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
++ interpreter with characters outside the Basic Multilingual Plane (higher than
++ 0x10000).
++
++- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
++ TypeError instead of giving a DeprecationWarning when a float is parsed using
++ the 'L' code (for long long). (All other integer codes already raise
++ TypeError in this case.)
++
++- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
++ enable shortcuts for upper case encoding name. Add also a shortcut for
++ "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
++
++- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
++ doesn't support "char buffer" anymore in Python 3.
++
++- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
++ instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
++ like bytearray.
++
++- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
++ used anymore and it was never documented.
++
++- In str.format(), raise a ValueError when indexes to arguments are too large.
++
++- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
++ integers n (including n = -909).
++
++- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
++ of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
++ easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
++ equal value.
++
++- Issue #8748: Fix two issues with comparisons between complex and integer
++ objects. (1) The comparison could incorrectly return True in some cases
++ (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
++ (2) The comparison raised an OverflowError for large integers, leading to
++ unpredictable exceptions when combining integers and complex objects in sets
++ or dicts.
++
++- Issue #8766: Initialize _warnings module before importing the first module.
++ Fix a crash if an empty directory called "encodings" exists in sys.path.
++
++- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
++ encoding and surrogateescape error handler instead of the locale encoding to
++ be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
++
++- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
++ of strict) error handler to escape surrogates.
++
++- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
++ object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
++ handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
++ back to UTF-8.
++
++- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
++ error handler, not only the default error handler (strict).
++
++- Issue #8610: Load file system codec at startup, and display a fatal error on
++ failure. Set the file system encoding to utf-8 (instead of None) if getting
++ the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
++
++- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
++ PyUnicode_FromString() to support surrogates in the filename and use the right
++ encoding.
++
++- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
++
++- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
++
++- Issue #8419: Prevent the dict constructor from accepting non-string keyword
++ arguments.
++
++- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
++ indirectly Python signal handlers anymore because mywrite() ignores exceptions
++ (KeyboardInterrupt).
++
++- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
++ unicode string (eg. backslashreplace).
++
++- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
++ anymore, you have to convert your bytearray filenames to bytes.
++
++- Issue #7332: Remove the 16KB stack-based buffer in
++ PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
++ compared to the dynamic memory allocation fallback. Patch by Charles-François
++ Natali.
++
++- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
++ passed to bytes or bytearray.
++
++- Issue #7301: Add environment variable $PYTHONWARNINGS.
++
++- Issue #8329: Don't return the same lists from select.select when no fds are
++ changed.
++
++- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error' on
++ 64-bit machines. The shift count for either left or right shift is permitted
++ to be up to sys.maxsize.
++
++- Ensure that tokenization of identifiers is not affected by locale.
++
++- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
++
++- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
++
++- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
++ is set.
++
++- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
++ is unknown.
++
++- Issue #1583863: A str subclass can now override the __str__ method.
++
++- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
++ PyMemberDefs could produce an internal error; raise TypeError instead.
++
++- Issue #7845: Rich comparison methods on the complex type now return
++ NotImplemented rather than raising a TypeError when comparing with an
++ incompatible type; this allows user-defined classes to implement their own
++ comparisons with complex.
++
++- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
++ (SIGINT). If an error occurs while importing the site module, the error is
++ printed and Python exits. Initialize the GIL before importing the site module.
++
++- Issue #7173: Generator finalization could invalidate sys.exc_info().
++
++- Issue #7544: Preallocate thread memory before creating the thread to avoid a
++ fatal error in low memory condition.
++
++- Issue #7820: The parser tokenizer restores all bytes in the right if the BOM
++ check fails.
++
++- Handle errors from looking up __prepare__ correctly.
++
++- Issue #5939: Add additional runtime checking to ensure a valid capsule in
++ Modules/_ctypes/callproc.c.
++
++- Issue #7309: Fix unchecked attribute access when converting
++ UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to strings.
++
++- Issue #6902: Fix problem with built-in types format incorrectly with 0
++ padding.
++
++- Issue #7988: Fix default alignment to be right aligned for complex.__format__.
++ Now it matches other numeric types.
++
++- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
++ PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string and
++ PyOS_string_to_double instead. See issue #5835 for the original deprecations.
++
++- Issue #7385: Fix a crash in `MemoryView_FromObject` when `PyObject_GetBuffer`
++ fails. Patch by Florent Xicluna.
++
++- Issue #7788: Fix an interpreter crash produced by deleting a list slice with
++ very large step value.
++
++- Issue #7766: Change sys.getwindowsversion() return value to a named tuple and
++ add the additional members returned in an OSVERSIONINFOEX structure. The new
++ members are service_pack_major, service_pack_minor, suite_mask, and
++ product_type.
++
++- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`) could
++ crash in many places because of the PyByteArray_AS_STRING() macro returning
++ NULL. The macro now returns a statically allocated empty string instead.
++
++- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
++ where the right hand operand is a set of constants, by turning the set into a
++ frozenset and pre-building it as a constant. The comparison operation is made
++ against the constant instead of building a new set each time it is executed (a
++ similar optimization already existed which turned a list of constants into a
++ pre-built tuple). Patch and additional tests by Dave Malcolm.
++
++- Issue #7622: Improve the split(), rsplit(), splitlines() and replace() methods
++ of bytes, bytearray and unicode objects by using a common implementation based
++ on stringlib's fast search. Patch by Florent Xicluna.
++
++- Issue #7632: Fix various str -> float conversion bugs present in 2.7 alpha 2,
++ including: (1) a serious 'wrong output' bug that could occur for long (> 40
++ digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
++ parsing certain long numeric strings corresponding to subnormal values, (3) a
++ memory leak for some values large enough to cause overflow, and (4) a number
++ of flaws that could lead to incorrectly rounded results.
++
++- The __complex__ method is now looked up on the class of instances to make it
++ consistent with other special methods.
++
++- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
++ `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
++
++- Issue #7604: Deleting an unset slotted attribute did not raise an
++ AttributeError.
++
++- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
++ in ** operator. The behaviour now conforms to that described in C99 Annex F.
++
++- Issue #1811: improve accuracy and cross-platform consistency for true division
++ of integers: the result of a/b is now correctly rounded for ints a and b (at
++ least on IEEE 754 platforms), and in particular does not depend on the
++ internal representation of an int.
++
++- Issue #6834: replace the implementation for the 'python' and 'pythonw'
++ executables on OSX.
++
++ These executables now work properly with the arch(1) command: ``arch -ppc
++ python`` will start a universal binary version of python in PPC mode (unlike
++ previous releases).
++
++- Issue #7466: Segmentation fault when the garbage collector is called in the
++ middle of populating a tuple. Patch by Florent Xicluna.
++
++- Issue #7419: setlocale() could crash the interpreter on Windows when called
++ with invalid values.
++
++- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
++ mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
++
++- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
++ 10.6.
++
++- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
++
++- Issue #6970: Remove redundant calls when comparing objects that don't
++ implement the relevant rich comparison methods.
++
++- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
++ range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
++ long but the length of the range did not. Also fix several cases where
++ reversed(range(a, b, c)) gave wrong results, and fix a refleak for
++ reversed(range(a, b, c)) with large arguments.
++
++- Issue #7244: itertools.izip_longest() no longer ignores exceptions raised
++ during the formation of an output tuple.
++
++- Issue #3297: On wide unicode builds, do not split unicode characters into
++ surrogates.
++
++- Remove length limitation when constructing a complex number from a string.
++
++- Issue #1087418: Boost performance of bitwise operations for longs.
++
++- Support for AtheOS has been completely removed from the code base. It was
++ disabled since Python 3.0.
++
++- Support for several legacy threading libraries has been disabled. These
++ libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
++ will be entirely removed in 3.3.
++
++- Support for OSF* has been disabled. If nobody stands up, support will be
++ removed in 3.3. See <http://bugs.python.org/issue8606>.
++
++- Peephole constant folding had missed UNARY_POSITIVE.
++
++- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
++ fixes the problem of some exceptions being thrown at shutdown when the
++ interpreter is killed. Patch by Adam Olsen.
++
++- Issue #7147: Remove support for compiling Python without complex number
++ support.
++
++- Issue #7120: logging: Removed import of multiprocessing which is causing crash
++ in GAE.
++
++- Issue #1754094: Improve the stack depth calculation in the compiler. There
++ should be no other effect than a small decrease in memory use. Patch by
++ Christopher Tur Lesniewski-Laas.
++
++- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when using
++ byte values greater than 127. Patch by Derk Drukker.
++
++- Issue #1571184: The Unicode database contains properties for more characters.
++ The tables for code points representing numeric values, white spaces or line
++ breaks are now generated from the official Unicode Character Database files,
++ and include information from the Unihan.txt file.
++
++- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of
++ producing internally inconsistent Python longs.
++
++- Issue #6990: Fix threading.local subclasses leaving old state around after a
++ reference cycle GC which could be recycled by new locals.
++
++- Issue #5460: Fix an ambiguity in the grammar.
++
++- Issue #1766304: Improve performance of membership tests on range objects.
++
++- Issue #6713: Improve performance of integer -> string conversions.
++
++- Issue #6846: Fix bug where bytearray.pop() returns negative integers.
++
++- Issue #6750: A text file opened with io.open() could duplicate its output when
++ writing from multiple threads at the same time.
++
++- Issue #6707: dir() on an uninitialized module caused a crash.
++
++- Issue #6540: Fixed crash for bytearray.translate() with invalid parameters.
++
++- Issue #6573: set.union() stopped processing inputs if an instance of self
++ occurred in the argument chain.
++
++- Issue #6070: On posix platforms import no longer copies the execute bit from
++ the .py file to the .pyc file if it is set.
++
++- Issue #1616979: Added the cp720 (Arabic DOS) encoding.
++
++- Issue #6428: Since Python 3.0, the __bool__ method must return a bool object,
++ and not an int. Fix the corresponding error message, and the documentation.
++
++- The deprecated PyCObject has been removed.
++
++- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
++ build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
++ of stdint.h on that platform.
++
++- Issue #6373: Fixed a SystemError when encoding with the latin-1 codec and the
++ 'surrogateescape' error handler, a string which contains unpaired surrogates.
++
++- Issue #4856: Remove checks for win NT.
++
++- Issue #6687: PyBytes_FromObject() no longer accepts an integer as its argument
++ to construct a null-initialized bytes object.
++
++- Issue #1023290: Add from_bytes() and to_bytes() methods to integers. These
++ methods allow the conversion of integers to bytes, and vice-versa.
++
++- Issue #7382: Fix bug in bytes.__getnewargs__ that prevented bytes instances
++ from being copied with copy.copy(), and bytes subclasses from being pickled
++ properly.
++
++- Code objects now support weak references.
++
++- Issue #7072: isspace(0xa0) is true on Mac OS X.
++
++- Issue #8084: PEP 370 now conforms to system conventions for framework builds
++ on MacOS X. That is, "python setup.py install --user" will install into
++ "~/Library/Python/2.7" instead of "~/.local".
++
++C-API
++-----
++
++- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
++ variable argument list. `Py_VA_COPY` is equivalent to C99
++ `va_copy`, but available on all python platforms.
++
++- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
++ instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
++ "step = -step" when reversing a slice.
++
++- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the
++ interpreter to set sys.argv without also modifying sys.path. This helps fix
++ `CVE-2008-5983
++ <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
++
++- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
++ strings in an efficient manner.
++
++- Issue #8276: PyEval_CallObject() is now only available in macro form. The
++ function declaration, which was kept for backwards compatibility reasons, is
++ now removed (the macro was introduced in 1997!).
++
++- Issue #7767: New function PyLong_AsLongLongAndOverflow added, analogous to
++ PyLong_AsLongAndOverflow.
++
++- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
++ has '\0' at the end.
++
++- Issue #5080: The argument parsing functions PyArg_ParseTuple,
++ PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
++ PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
++ 'L' format code. This will become a TypeError in a future version of Python,
++ to match the behaviour of the other integer format codes.
++
++- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.
++
++- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments) in
++ PyArg_ParseTupleAndKeywords.
++
++- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V) and
++ PyErr_Format, on machines with HAVE_LONG_LONG defined.
++
++- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
++ PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
++ accessing the d_type and d_name members of structures using PyDescr_COMMON.
++
++- Issue #6405: Remove duplicate type declarations in descrobject.h.
++
++- The code flags for old __future__ features are now available again.
++
++- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
++ PyCode_Addr2Line().
++
++- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
++ object at a specified file, function, and line number.
++
++- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
++ ``const char *`` as the string is stored beyond the call.
++
++- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
++ allocator will be automatically disabled when running under Valgrind. This
++ gives improved memory leak detection when running under Valgrind, while taking
++ advantage of pymalloc at other times.
++
++Library
++-------
++
++- In pdb, when Ctrl-C is entered while defining commands for a breakpoint, the
++ old commands are restored.
++
++- For traceback debugging, the pdb listing now also shows the locations where
++ the exception was originally (re)raised, if it differs from the last line
++ executed (e.g. in case of finally clauses).
++
++- The pdb command "source" has been added. It displays the source code for a
++ given object, if possible.
++
++- The pdb command "longlist" has been added. It displays the whole source code
++ for the current function.
++
++- Issue #1503502: Make pdb.Pdb easier to subclass by putting message and error
++ output into methods.
++
++- Issue #809887: Make the output of pdb's breakpoint deletions more consistent;
++ emit a message when a breakpoint is enabled or disabled.
++
++- Issue #5294: Fix the behavior of pdb's "continue" command when called in the
++ top-level debugged frame.
++
++- Issue #5727: Restore the ability to use readline when calling into pdb in
++ doctests.
++
++- Issue #6719: In pdb, do not stop somewhere in the encodings machinery if the
++ source file to be debugged is in a non-builtin encoding.
++
++- Issue #8048: Prevent doctests from failing when sys.displayhook has been
++ reassigned.
++
++- Issue #8015: In pdb, do not crash when an empty line is entered as a
++ breakpoint command.
++
++- In pdb, allow giving a line number to the "until" command.
++
++- Issue #1437051: For pdb, allow "continue" and related commands in .pdbrc
++ files. Also, add a command-line option "-c" that runs a command as if given
++ in .pdbrc.
++
++- Issue #4179: In pdb, allow "list ." as a command to return to the currently
++ debugged line.
++
++- Issue #4108: In urllib.robotparser, if there are multiple ``User-agent: *``
++ entries, consider the first one.
++
++- Issue #6630: Allow customizing regex flags when subclassing the
++ string.Template class.
++
++- Issue #9411: Allow specifying an encoding for config files in the configparser

++
++- Issue #9354: Provide getsockopt() in asyncore's file_wrapper.
++
++- Issue #8966: ctypes: Remove implicit bytes-unicode conversion.
++
++- Issue #9378: python -m pickle <pickle file> will now load and display the
++ first object in the pickle file.
++
++- Issue #4770: Restrict binascii module to accept only bytes (as specified).
++ And fix the email package to encode to ASCII instead of ``raw-unicode-escape``
++ before ASCII-to-binary decoding.
++
++- Issue #9384: ``python -m tkinter`` will now display a simple demo applet.
++
++- The default size of the re module's compiled regular expression cache has been
++ increased from 100 to 500 and the cache replacement policy has changed from
++ simply clearing the entire cache on overflow to forgetting the least recently
++ used cached compiled regular expressions. This is a performance win for
++ applications that use a lot of regular expressions and limits the impact of
++ the performance hit anytime the cache is exceeded.
++
++- Issue #7113: Speed up loading in configparser. Patch by Åukasz Langa.
++
++- Issue #9032: XML-RPC client retries the request on EPIPE error. The EPIPE
++ error occurs when the server closes the socket and the client sends a big
++ XML-RPC request.
++
++- Issue #4629: getopt raises an error if an argument ends with "=", whereas
++ getopt doesn't accept a value (eg. --help= is rejected if getopt uses
++ ['help='] long options).
++
++- Issue #7989: Added pure python implementation of the `datetime` module. The C
++ module is renamed to `_datetime` and if available, overrides all classes
++ defined in datetime with fast C impementation. Python implementation is based
++ on the original python prototype for the datetime module by Tim Peters with
++ minor modifications by the PyPy project. The test suite now tests `datetime`
++ module with and without `_datetime` acceleration using the same test cases.
++
++- Issue #7895: platform.mac_ver() no longer crashes after calling os.fork().
++
++- Issue #9323: Fixed a bug in trace.py that resulted in loosing the name of the
++ script being traced. Patch by Eli Bendersky.
++
++- Issue #9282: Fixed --listfuncs option of trace.py. Thanks Eli Bendersky for
++ the patch.
++
++- Issue #3704: http.cookiejar was not properly handling URLs with a / in the
++ parameters.
++
++- Issue #9268: ``pickletools.dis()`` now has an optional *annotate* argument
++ which controls printing of opcode descriptions in ``dis()`` output.
++
++- Issue #1555570: email no longer inserts extra blank lines when a \r\n combo
++ crosses an 8192 byte boundary.
++
++- Issue #9243: Fix sndhdr module and add unit tests, contributed by James Lee.
++
++- ``ast.literal_eval()`` now allows byte literals.
++
++- Issue #9137: Fix issue in MutableMapping.update, which incorrectly treated
++ keyword arguments called 'self' or 'other' specially.
++
++- ``ast.literal_eval()`` now allows set literals.
++
++- Issue #9164: Ensure that sysconfig handles duplicate -arch flags in CFLAGS.
++
++- Issue #7646: The fnmatch pattern cache no longer grows without bound.
++
++- Issue #9136: Fix 'dictionary changed size during iteration' RuntimeError
++ produced when profiling the decimal module. This was due to a dangerous
++ iteration over 'locals()' in Context.__init__.
++
++- Fix extreme speed issue in Decimal.pow when the base is an exact power of 10
++ and the exponent is tiny (for example, ``Decimal(10) **
++ Decimal('1e-999999999')``).
++
++- Issue #9186: Fix math.log1p(-1.0) to raise ValueError, not OverflowError.
++
++- Issue #9130: Fix validation of relative imports in parser module.
++
++- Issue #9128: Fix validation of class decorators in parser module.
++
++- Issue #9094: python -m pickletools will now disassemble pickle files listed in
++ the command line arguments. See output of python -m pickletools -h for more
++ details.
++
++- Issue #5468: urlencode to handle bytes type and other encodings in its query
++ parameter. Patch by Dan Mahn.
++
++- Issue #7673: Fix security vulnerability (CVE-2010-2089) in the audioop module,
++ ensure that the input string length is a multiple of the frame size.
++
++- Issue #6507: Accept source strings in dis.dis(). Original patch by Daniel
++ Urban.
++
++- Issue #7829: Clearly document that the dis module is exposing an
++ implementation detail that is not stable between Python VMs or releases.
++
++- Issue #6589: cleanup asyncore.socket_map in case smtpd.SMTPServer constructor
++ raises an exception.
++
++- Issue #9110: Addition of ContextDecorator to contextlib, for creating APIs
++ that act as both context managers and decorators. contextmanager changes to
++ use ContextDecorator.
++
++- Implement importlib.abc.SourceLoader and deprecate PyLoader and PyPycLoader
++ for removal in Python 3.4.
++
++- Issue #9064: pdb's "up" and "down" commands now accept an optional argument
++ giving the number of frames to go.
++
++- Issue #9018: os.path.normcase() now raises a TypeError if the argument is not
++ ``str`` or ``bytes``.
++
++- Issue #9075: In the ssl module, remove the setting of a ``debug`` flag on an
++ OpenSSL structure.
++
++- Issue #8682: The ssl module now temporary increments the reference count of a
++ socket object got through ``PyWeakref_GetObject``, so as to avoid possible
++ deallocation while the object is still being used.
++
++- Issue #1368368: FancyURLOpener class changed to throw an Exception on wrong
++ password instead of presenting an interactive prompt. Older behavior can be
++ obtained by passing retry=True to http_error_xxx methods of FancyURLOpener.
++
++- Issue #8720: Fix regression caused by fix for #4050 by making getsourcefile
++ smart enough to find source files in the linecache.
++
++- Issue #5610: feedparser no longer eats extra characters at the end of a body
++ part if the body part ends with a ``\r\n``.
++
++- Issue #8986: math.erfc was incorrectly raising OverflowError for values
++ between -27.3 and -30.0 on some platforms.
++
++- Issue #8784: Set tarfile default encoding to 'utf-8' on Windows.
++
++- Issue #8966: If a ctypes structure field is an array of c_char, convert its
++ value to bytes instead of str (as done for c_char and c_char_p).
++
++- Issue #8188: Comparisons between Decimal and Fraction objects are now
++ permitted, returning a result based on the exact numerical values of the
++ operands. This builds on issue #2531, which allowed Decimal-to-float
++ comparisons; all comparisons involving numeric types (bool, int, float,
++ complex, Decimal, Fraction) should now act as expected.
++
++- Issue #8897: Fix sunau module, use bytes to write the header. Patch written by
++ Thomas Jollans.
++
++- Issue #8899: time.struct_time now has class and attribute docstrings.
++
++- Issue #6470: Drop UNC prefix in FixTk.
++
++- Issue #4768: base64 encoded email body parts were incorrectly stored as binary
++ strings. They are now correctly converted to strings.
++
++- Issue #8833: tarfile created hard link entries with a size field != 0 by
++ mistake.
++
++- Charset.body_encode now correctly handles base64 encoding by encoding with the
++ output_charset before calling base64mime.encode. Passes the tests from 2.x
++ issue #1368247.
++
++- Issue #8845: sqlite3 Connection objects now have a read-only in_transaction
++ attribute that is True iff there are uncommitted changes.
++
++- Issue #1289118: datetime.timedelta objects can now be multiplied by float and
++ divided by float and int objects. Results are rounded to the nearest multiple

++
++- Issue #7150: Raise OverflowError if the result of adding or subtracting
++ timedelta from date or datetime falls outside of the MINYEAR:MAXYEAR range.
++
++- Issue #8806: add SSL contexts support to ftplib.
++
++- Issue #4769: Fix main() function of the base64 module, use sys.stdin.buffer
++ and sys.stdout.buffer (instead of sys.stdin and sys.stdout) to use the bytes
++ API.
++
++- Issue #8770: Now sysconfig displays information when it's called as a script.
++ Initial idea by Sridhar Ratnakumar.
++
++- Issue #6662: Fix parsing of malformatted charref (&#bad;), patch written by
++ Fredrik Håård.
++
++- Issue #8540: Decimal module: rename the Context._clamp attribute to
++ Context.clamp and make it public. This is useful in creating contexts that
++ correspond to the decimal interchange formats specified in IEEE 754.
++
++- Issue #6268: Fix seek() method of codecs.open(), don't read or write the BOM
++ twice after seek(0). Fix also reset() method of codecs, UTF-16, UTF-32 and
++ StreamWriter classes.
++
++- Issue #3798: sys.exit(message) writes the message to sys.stderr file, instead
++ of the C file stderr, to use stderr encoding and error handler.

++ correct encoding.
++
++- Issue #4870: Add an `options` attribute to SSL contexts, as well as several
++ ``OP_*`` constants to the `ssl` module. This allows to selectively disable
++ protocol versions, when used in combination with `PROTOCOL_SSLv23`.
++
++- Issue #8759: Fixed user paths in sysconfig for posix and os2 schemes.
++
++- Issue #8663: distutils.log emulates backslashreplace error handler. Fix
++ compilation in a non-ASCII directory if stdout encoding is ASCII (eg. if
++ stdout is not a TTY).
++
++- Issue #8513: os.get_exec_path() supports b'PATH' key and bytes value.
++ subprocess.Popen() and os._execvpe() support bytes program name. Add
++ os.supports_bytes_environ flag: True if the native OS type of the environment

++
++- The audioop module now supports sound fragments of length greater than 2**31
++ bytes on 64-bit machines, and is PY_SSIZE_T_CLEAN.
++
++- Issue #4972: Add support for the context manager protocol to the ftplib.FTP
++ class.
++
++- Issue #8664: In py_compile, create __pycache__ when the compiled path is
++ given.
++

++
++- Issue #8571: Fix an internal error when compressing or decompressing a chunk
++ larger than 1GB with the zlib module's compressor and decompressor objects.
++
++- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
++ mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
++ file system encoding with the surrogateescape error handler (instead of
++ utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
++
++- Issue #8573: asyncore _strerror() function might throw ValueError.
++
++- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
++ messages when accessing undefined class attributes because of the cheap
++ inheritance with the underlying socket object. The cheap inheritance has been
++ deprecated.
++
++- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
++ Patch by Tres Seaver.
++
++- Issue #8390: tarfile uses surrogateescape as the default error handler
++ (instead of replace in read mode or strict in write mode).
++
++- Issue #7755: Use an unencumbered audio file for tests.
++
++- Issue #8621: uuid.uuid4() returned the same sequence of values in the parent
++ and any children created using ``os.fork`` on MacOS X 10.6.
++
++- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
++ operation raises multiple signals and more than one of those signals is
++ trapped, the specification determines the order in which the signals should be
++ handled. In many cases this order wasn't being followed, leading to the wrong
++ Python exception being raised.
++
++- Issue #7865: The close() method of ``io`` objects should not swallow
++ exceptions raised by the implicit flush(). Also qensure that calling close()
++ several times is supported. Patch by Pascal Chambon.
++
++- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
++ gc.DEBUG_STATS.
++
++- Issue #8354: The siginterrupt setting is now preserved for all signals, not
++ just SIGCHLD.
++
++- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
++ webbrowser.get("safari").

++ the Linux kernel. Patch by Yaniv Aknin.
++
++- Issue #8295: Added shutil.unpack_archive.
++
++- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
++ It should correctly return an empty response now.

++- Issue #6656: fix locale.format_string to handle escaped percents
++ and mappings.
++
++- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
++ the method could block indefinitely if called just before the event loop
++ started running. This also fixes the occasional freezes witnessed in
++ test_httpservers.
++
++- Issue #8524: When creating an SSL socket, the timeout value of the original
++ socket wasn't retained (instead, a socket with a positive timeout would be
++ turned into a non-blocking SSL socket).
++
++- Issue #5103: SSL handshake would ignore the socket timeout and block
++ indefinitely if the other end didn't respond.
++
++- The do_handshake() method of SSL objects now adjusts the blocking mode of the
++ SSL structure if necessary (as other methods already do).
++
++- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and
++ bytes strings for environment keys and values.
++
++- Issue #8467: Pure Python implementation of subprocess encodes the error
++ message using surrogatepass error handler to support surrogates in the
++ message.
++
++- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames.
++
++- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
++ string "python" as the *ident*. openlog() arguments are all optional and
++ keywords.
++
++- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
++ non-infinite timeout. Also make that method friendlier with applications
++ wanting to continue using the socket in clear-text mode, by disabling
++ OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
++
++- Issue #8496: make mailcap.lookup() always return a list, rather than an
++ iterator. Patch by Gregory Nofi.
++
++- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
++ collation name contains a surrogate character.
++
++- Issue #8484: Load all ciphers and digest algorithms when initializing the _ssl
++ extension, such that verification of some SSL certificates doesn't fail
++ because of an "unknown algorithm".
++
++- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
++
++- Issue #1540112: Now allowing the choice of a copy function in shutil.copytree.
++
++- Issue #4814: timeout parameter is now applied also for connections resulting
++ from PORT/EPRT commands.
++
++- Issue #8463: added missing reference to bztar in shutil's documentation.
++
++- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6 (as
++ long as the user didn't specify 'automatic proxy configuration').

++ surrogates.
++
++- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
++ `threading.Semaphore` objects. Original patch by Torsten Landschoff.
++
++- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
++ available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
++
++- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
++ the current working directory.
++
++- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
++ using backslashreplace error handler.
++
++- Issue #8412: os.system() now accepts bytes, bytearray and str with surrogates.
++
++- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
++ Locke and Hans Ulrich Niedermann.
++
++- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
++
++- Issue #7316: The acquire() method of lock objects in the ``threading``
++ module now takes an optional timeout argument in seconds. Timeout support
++ relies on the system threading library, so as to avoid a semi-busy wait loop.
++
++- Issue #8383: pickle and pickletools use surrogatepass error handler when
++ encoding unicode as utf8 to support lone surrogates and stay compatible with
++ Python 2.x and 3.x.
++
++- Issue #7585: difflib context and unified diffs now place a tab between
++ filename and date, conforming to the 'standards' they were originally designed
++ to follow. This improves compatibility with patch tools.
++
++- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
++ character sets will now consistently use a Content-Transfer-Encoding of 7bit
++ rather than sometimes being marked as 8bit.
++
++- Issue #8375: test_distutils now checks if the temporary directory are still
++ present before it cleans them.
++
++- Issue #8374: Update the internal alias table in the ``locale`` module to
++ cover recent locale changes and additions.
++
++- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
++ using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
++ `ssl.OPENSSL_VERSION_NUMBER`.
++
++- Add functools.total_ordering() and functools.cmp_to_key().
++
++- Issue #8257: The Decimal construct now accepts a float instance directly,
++ converting that float to a Decimal of equal value:
++
++ >>> Decimal(1.1)
++ Decimal('1.100000000000000088817841970012523233890533447265625')
++
++- Issue #8294: The Fraction constructor now accepts Decimal and float instances
++ directly.
++
++- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
++ InvalidOperation instead of returning False. (Comparisons involving a quiet
++ NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
++ signaling NaNs remain unhashable.
++
++- Issue #2531: Comparison operations between floats and Decimal instances now
++ return a result based on the numeric values of the operands; previously they
++ returned an arbitrary result based on the relative ordering of id(float) and
++ id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
++ comparisons.
++
++- Added a subtract() method to collections.Counter().
++
++- Issue #8233: When run as a script, py_compile.py optionally takes a single
++ argument `-` which tells it to read files to compile from stdin. Each line is
++ read on demand and the named file is compiled immediately. (Original patch by
++ Piotr Ożarowski).
++
++- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
++ form feed (0x0C) are now considered linebreaks, as specified in Unicode
++ Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
++
++- Comparisons using one of <, <=, >, >= between a complex instance and a
++ Fractions instance now raise TypeError instead of returning True/False. This
++ makes Fraction <=> complex comparisons consistent with int <=> complex, float
++ <=> complex, and complex <=> complex comparisons.
++
++- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some
++ methods (such as oss_mixer_device.fileno()) were not available. Initial patch
++ by Bertrand Janin.
++
++- Issue #8205: Remove the "Modules" directory from sys.path when Python is
++ running from the build directory (POSIX only).
++
++- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
++ didn't support chflags() (for example ZFS under FreeBSD). The error is now
++ silenced.
++
++- Issue #7860: platform.uname now reports the correct 'machine' type when Python
++ is running in WOW64 mode on 64 bit Windows.
++
++- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
++ Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
++ reads and writes are always retried by OpenSSL itself.
++
++- Issue #4282: Fix the main function of the profile module for a non-ASCII
++ script, open the file in binary mode and not in text mode with the default
++ (utf8) encoding.
++
++- Issue #8179: Fix macpath.realpath() on a non-existing path.
++
++- Issue #8024: Update the Unicode database to 5.2.

++- Issue #8168: py_compile now handles files with utf-8 BOMS.
++
++- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
++ detected.
++
++- Issue #6716/2: Backslash-replace error output in compilall.
++
++- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
++ with Tcl/Tk-8.5.
++
++- Issue #8140: extend compileall to compile single files. Add -i option.
++
++- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of the
++ locale.
++
++- The internals of the subprocess module on POSIX systems have been replaced by
++ an extension module (_posixsubprocess) so that the fork()+exec() can be done
++ safely without the possibility of deadlock in multithreaded applications.
++
++- subprocess.Popen now has restore_signals and start_new_session features. The
++ default of restore_signals=True is a new behavior compared to earlier Python
++ versions. This means that signals such as SIGPIPE are not ignored by default
++ in subprocesses launched by Python (Issue #1652).
++
++- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
++ cElementTree module is updated too.
++
++- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
++ an non existent program name and Python is unable to retrieve the real program
++ name.
++
++- Issue #7880: Fix sysconfig when the python executable is a symbolic link.
++
++- Issue #6509: fix re.sub to work properly when the pattern, the string, and the
++ replacement were all bytes. Patch by Antoine Pitrou.
++
++- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
++ bugs and allows loading SQLite extensions from shared libraries.
++
++- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public
++ Review Issue #29 (http://unicode.org/review/pr-29.html).
++
++- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
++ reset also the pointer to the current pointer context.
++
++- Issue #7232: Add support for the context manager protocol to the TarFile
++ class.
++
++- Issue #7250: Fix info leak of os.environ across multi-run uses of
++ wsgiref.handlers.CGIHandler.
++

++- Issue #7869: logging: improved diagnostic for format-time errors.
++
++- Issue #7868: logging: added loggerClass attribute to Manager.
++
++- logging: Implemented PEP 391.

++
++- Issue #7959: ctypes callback functions are now registered correctly with the
++ cycle garbage collector.
++
++- Issue #5801: removed spurious empty lines in wsgiref.
++
++- Issue #6666: fix bug in trace.py that applied the list of directories to be
++ ignored only to the first file. Noted by Bogdan Opanchuk.
++
++- Issue #7597: curses.use_env() can now be called before initscr(). Noted by
++ Kan-Ru Chen.
++
++- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

++ bytecode file when it was less then 8 bytes.
++
++- Issue #7633: In the decimal module, Context class methods (with the exception
++ of canonical and is_canonical) now accept instances of int and long wherever a
++ Decimal instance is accepted, and implicitly convert that argument to Decimal.
++ Previously only some arguments were converted.
++
++- Issue #7835: shelve should no longer produce mysterious warnings during
++ interpreter shutdown.
++
++- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in XML
++ processing instructions and comments. These raw characters are allowed by the
++ XML specification, and are necessary when outputting e.g. PHP code in a
++ processing instruction. Patch by Neil Muller.
++
++- Issue #6233: ElementTree failed converting unicode characters to XML entities
++ when they could't be represented in the requested output encoding. Patch by
++ Jerry Chen.
++
++- Issue #6003: add an argument to ``zipfile.Zipfile.writestr`` to specify the
++ compression type.
++
++- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
++ specified, rather than fall through to AF_PACKET (in the `socket` module).
++ Also, raise ValueError rather than TypeError when an unknown TIPC address type
++ is specified. Patch by Brian Curtin.
++
++- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
++ position when calling `truncate()`. It would previously change the file
++ position to the given argument, which goes against the tradition of
++ ftruncate() and other truncation APIs. Patch by Pascal Chambon.
++
++- Issue #7610: Reworked implementation of the internal
++ ``zipfile.ZipExtFile`` class used to represent files stored inside an
++ archive. The new implementation is significantly faster and can be wrapped in
++ a ``io.BufferedReader`` object for more speedups. It also solves an
++ issue where interleaved calls to `read()` and `readline()` give wrong results.
++ Patch by Nir Aides.
++
++- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
++ allowing for a maximum number of tasks within the pool to be completed by the
++ worker before that worker is terminated, and a new one created to replace it.
++
++- Issue #7792: Registering non-classes to ABCs raised an obscure error.
++

++ by Brian Curtin.
++
++- Issue #7681: Use floor division in appropiate places in the wave module.
++
++- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since
++ Extension extra options may change the output without changing the .c
++ file). Initial patch by Collin Winter.
++
++- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc
++ when it has a fully qualified configuration prefix. Initial patch by Arfrever.
++
++- Issue #7105: Make WeakKeyDictionary and WeakValueDictionary robust against the
++ destruction of weakref'ed objects while iterating.
++
++- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by Victor
++ Stinner.
++
++- Issue #1628205: Socket file objects returned by socket.socket.makefile() now
++ properly handles EINTR within the read, readline, write & flush methods. The
++ socket.sendall() method now properly handles interrupted system calls.
++
++- Issue #7471: Improve the performance of GzipFile's buffering mechanism, and
++ make it implement the `io.BufferedIOBase` ABC to allow for further speedups by
++ wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
++
++- Issue #3972: http.client.HTTPConnection now accepts an optional source_address
++ parameter to allow specifying where your connections come from.
++
++- socket.create_connection now accepts an optional source_address parameter.
++
++- Issue #5511: now zipfile.ZipFile can be used as a context manager. Initial
++ patch by Brian Curtin.
++
++- Issue #7556: Make sure Distutils' msvc9compile reads and writes the MSVC XML
++ Manifest file in text mode so string patterns can be used in regular
++ expressions.
++
++- Issue #7552: Removed line feed in the base64 Authorization header in the
++ Distutils upload command to avoid an error when PyPI reads it. This occurs on
++ long passwords. Initial patch by JP St. Pierre.
++
++- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by
++ Tatsuhiro Tsujikawa.
++
++- Issue #4757: `zlib.compress` and other methods in the zlib module now raise a
++ TypeError when given an `str` object (rather than a `bytes`-like object).
++ Patch by Victor Stinner and Florent Xicluna.
++
++- Issue #7349: Make methods of file objects in the io module accept None as an
++ argument where file-like objects (ie StringIO and BytesIO) accept them to mean
++ the same as passing no argument.
++
++- Issue #7357: tarfile no longer suppresses fatal extraction errors by default.
++
++- Issue #5949: added check for correct lineends in input from IMAP server in
++ imaplib.
++
++- Add count() and reverse() methods to collections.deque().
++
++- Fix variations of extending deques: d.extend(d) d.extendleft(d) d+=d

++ msvc9compiler.
++
++- Issue #7333: The `posix` module gains an `initgroups()` function providing

++ Patch by Jean-Paul Calderone.
++
++- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
++ ownership when the group is not forced, because the group may be different
++ from the user's group and inherit from its container when the test is run.
++
++- Issue #4486: When an exception has an explicit cause, do not print its
++ implicit context too. This affects the `traceback` module as well as built-in
++ exception printing.
++
++- Issue #1515: Enable use of deepcopy() with instance methods. Patch by Robert
++ Collins.
++
++- Issue #7403: logging: Fixed possible race condition in lock creation.
++
++- Issue #6845: Add restart support for binary upload in ftplib. The
++ `storbinary()` method of FTP and FTP_TLS objects gains an optional `rest`
++ argument. Patch by Pablo Mouzo.
++
++- Issue #5788: `datetime.timedelta` objects get a new `total_seconds()` method
++ returning the total number of seconds in the duration. Patch by Brian
++ Quinlan.
++
++- Issue #7133: SSL objects now support the new buffer API.
++
++- Issue #1488943: difflib.Differ() doesn't always add hints for tab characters.
++
++- Issue #6123: tarfile now opens empty archives correctly and consistently
++ raises ReadError on empty files.
++
++- Issue #7354: distutils.tests.test_msvc9compiler - dragfullwindows can be 2.
++
++- Issue #5037: Proxy the __bytes__ special method instead to __bytes__ instead
++ of __str__.
++
++- Issue #7341: Close the internal file object in the TarFile constructor in case
++ of an error.
++
++- Issue #7293: distutils.test_msvc9compiler is fixed to work on any fresh
++ Windows box. Help provided by David Bolen.
++
++- Issue #2054: ftplib now provides an FTP_TLS class to do secure FTP using TLS
++ or SSL. Patch by Giampaolo Rodola'.
++
++- Issue #7328: pydoc no longer corrupts sys.path when run with the '-m' switch.
++
++- Issue #4969: The mimetypes module now reads the MIME database from the
++ registry under Windows. Patch by Gabriel Genellina.
++
++- Issue #6816: runpy now provides a run_path function that allows Python code to
++ execute file paths that refer to source or compiled Python files as well as
++ zipfiles, directories and other valid sys.path entries that contain a
++ __main__.py file. This allows applications that run other Python scripts to
++ support the same flexibility as the CPython command line itself.
++
++- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
++ connection with another process, rather than looping endlessly. The default
++ timeout is 20 seconds, which should be amply sufficient for local connections.
++
++- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and
++ unpickled. This fixes crashes under Windows when trying to run
++ test_multiprocessing in verbose mode.
++
++- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``
++ argument added to the TextTestRunner constructor allowing a different result
++ class to be used without having to subclass.
++
++- Issue #7588: ``unittest.TextTestResult.getDescription`` now includes the test
++ name in failure reports even if the test has a docstring.
++
++- Issue #3001: Add a C implementation of recursive locks which is used by
++ default when instantiating a `threading.RLock` object. This makes recursive
++ locks as fast as regular non-recursive locks (previously, they were slower by
++ 10x to 15x).
++
++- Issue #7282: Fix a memory leak when an RLock was used in a thread other than
++ those started through `threading.Thread` (for example, using
++ `_thread.start_new_thread()`).
++
++- Issue #7187: Importlib would not silence the IOError raised when trying to
++ write new bytecode when it was made read-only.
++
++- Issue #7264: Fix a possible deadlock when deallocating thread-local objects
++ which are part of a reference cycle.
++
++- Issue #7211: Allow 64-bit values for the `ident` and `data` fields of kevent
++ objects on 64-bit systems. Patch by Michael Broghton.
++
++- Issue #6896: mailbox.Maildir now invalidates its internal cache each time a
++ modification is done through it. This fixes inconsistencies and test failures
++ on systems with slightly bogus mtime behaviour.
++
++- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
++ from stdin so that existing input does not confuse it and lead to incorrect
++ entry or an IOError. It also properly flushes it afterwards to avoid the
++ terminal echoing the input afterwards on OSes such as Solaris.
++
++- Issue #7233: Fix a number of two-argument Decimal methods to make sure that
++ they accept an int or long as the second argument. Also fix buggy handling of
++ large arguments (those with coefficient longer than the current precision) in
++ shift and rotate.
++
++- Issue #4750: Store the basename of the original filename in the gzip FNAME
++ header as required by RFC 1952.
++
++- Issue #1180: Added a new global option to ignore ~/.pydistutils.cfg in
++ Distutils.

++- Issue #7099: Decimal.is_normal now returns True for numbers with exponent
++ larger than emax.
++
++- Issue #7080: locale.strxfrm() raises a MemoryError on 64-bit non-Windows
++ platforms, and assorted locale fixes by Derk Drukker.
++
++- Issue #5833: Fix extra space character in readline completion with the GNU
++ readline library version 6.0.
++
++- Issue #6894: Fixed the issue urllib2 doesn't respect "no_proxy" environment.
++
++- Issue #7086: Added TCP support to SysLogHandler, and tidied up some
++ anachronisms in the code which were a relic of 1.5.2 compatibility.
++
++- Issue #7082: When falling back to the MIME 'name' parameter, the correct place
++ to look for it is the Content-Type header.
++
++- Make tokenize.detect_coding() normalize utf-8 and iso-8859-1 variants like the
++ builtin tokenizer.
++
++- Issue #7048: Force Decimal.logb to round its result when that result is too
++ large to fit in the current precision.
++
++- Issue #6236, #6348: Fix various failures in the I/O library under AIX and
++ other platforms, when using a non-gcc compiler. Patch by Derk Drukker.
++
++- Issue #4606: Passing 'None' if ctypes argtype is set to POINTER(...) does now
++ always result in NULL.
++
++- Issue #5042: Structure sub-subclass does now initialize correctly with base
++ class positional arguments.
++
++- Issue #6882: Import uuid creates zombies processes.
++
++- Issue #6635: Fix profiler printing usage message.
++
++- Issue #6856: Add a filter keyword argument to TarFile.add().
++
++- Issue #6888: pdb's alias command was broken when no arguments were given.
++
++- Issue #6857: Default format() alignment should be '>' for Decimal instances.
++
++- Issue #6795: int(Decimal('nan')) now raises ValueError instead of returning
++ NaN or raising InvalidContext. Also, fix infinite recursion in
++ long(Decimal('nan')).
++
++- Issue #6850: Fix bug in Decimal._parse_format_specifier for formats with no
++ type specifier.
++
++- Issue #6239: ctypes.c_char_p return value must return bytes.
++
++- Issue #6838: Use a list to accumulate the value instead of repeatedly
++ concatenating strings in http.client's HTTPResponse._read_chunked providing a
++ significant speed increase when downloading large files servend with a
++ Transfer-Encoding of 'chunked'.
++
++- Trying to import a submodule from a module that is not a package, ImportError
++ should be raised, not AttributeError.
++
++- When the globals past to importlib.__import__() has __package__ set to None,
++ fall back to computing what __package__ should be instead of giving up.
++
++- Raise a TypeError when the name of a module to be imported for
++ importlib.__import__ is not a string (was raising an AttributeError before).
++
++- Allow the fromlist passed into importlib.__import__ to be any iterable.
++
++- Have importlib raise ImportError if None is found in sys.modules.
++
++- Issue #6054: Do not normalize stored pathnames in tarfile.
++
++- Issue #6794: Fix Decimal.compare_total and Decimal.compare_total_mag: NaN
++ payloads are now ordered by integer value rather than lexicographically.
++
++- Issue #1356969: Add missing info methods in tix.HList.
++
++- Issue #1522587: New constants and methods for the tix.Grid widget.

++- Issue #1135: Add the XView and YView mix-ins to avoid duplicating the xview*
++ and yview* methods.
++
++- Issue #6629: Fix a data corruption issue in the new I/O library, which could
++ occur when writing to a BufferedRandom object (e.g. a file opened in "rb+" or

++ POP3.apop.
++
++- Issue #2715: Remove remnants of Carbon.File from binhex module.
++
++- Issue #6595: The Decimal constructor now allows arbitrary Unicode decimal
++ digits in input, as recommended by the standard. Previously it was restricted

++- Issue #6106: telnetlib.Telnet.process_rawq doesn't handle default WILL/WONT
++ DO/DONT correctly.
++
++- Issue #1424152: Fix for http.client, urllib.request to support SSL while
++ working through proxy. Original patch by Christopher Li, changes made by
++ Senthil Kumaran.
++
++- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
++ loaders that allow for modules to be executed. Both importlib.abc.PyLoader and
++ PyPycLoader inherit from this class and provide implementations in relation to
++ other methods required by the ABCs.
++
++- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
++ the documentation said it did even though the code in PyLoader relied on the
++ abstract method required by ResourceLoader.
++
++- Issue #6431: Make Fraction type return NotImplemented when it doesn't know how
++ to handle a comparison without loss of precision. Also add correct handling
++ of infinities and nans for comparisons with float.
++
++- Issue #6415: Fixed warnings.warn segfault on bad formatted string.
++
++- Issue #6358: The exit status of a command started with os.popen() was reported

++
++- Issue #6323: The pdb debugger did not exit when running a script with a syntax
++ error.
++
++- Issue #3392: The subprocess communicate() method no longer fails in select()

++
++- Issue #6344: Fixed a crash of mmap.read() when passed a negative argument.
++
++- The deprecated function string.maketrans has been removed.
++
++- Issue #4005: Fixed a crash of pydoc when there was a zip file present in
++ sys.path.
++
++- Issue #6218: io.StringIO and io.BytesIO instances are now picklable.
++
++- The os.get_exec_path() function to return the list of directories that will be
++ searched for an executable when launching a subprocess was added.

++ instance stuck in initial state and present in threading.enumerate().
++
++- Issue #1068268: The subprocess module now handles EINTR in internal os.waitpid
++ and os.read system calls where appropriate.
++
++- Issue #6729: Added ctypes.c_ssize_t to represent ssize_t.
++
++- Issue #6247: The argparse module has been added to the standard library.

++ option available on FreeBSD 7.1 and newer.
++
++- Issue #9315: Fix for the trace module to record correct class name
++ for tracing methods.
++
++Extension Modules
++-----------------
++
++- Issue #9959: Tweak formula used for computing math.log of an integer,
++ making it marginally more accurate for exact powers of 2.
++
++- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
++
++- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
++ compared to other unix systems. In particular, os.getgroups() does not reflect
++ any changes made using os.setgroups() but basicly always returns the same
++ information as the id command. os.getgroups() can now return more than 16
++ groups on MacOSX.
++
++- Issue #6095: Make directory argument to os.listdir optional.
++
++- Issue #9277: Fix bug in struct.pack for bools in standard mode (e.g.,
++ struct.pack('>?')): if conversion to bool raised an exception then that
++ exception wasn't properly propagated on machines where char is unsigned.
++
++- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
++ they contain instances of old-style classes.
++
++- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany
++ existing isinf and isnan functions.
++
++- Issue #1578269: Implement os.symlink for Windows 6.0+. Patch by Jason
++ R. Coombs.
++
++- In struct.pack, correctly propogate exceptions from computing the truth of an
++ object in the '?' format.
++
++- Issue #9000: datetime.timezone objects now have eval-friendly repr.
++
++- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
++ special methods.
++
++- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
++ Prior to this change, timezone adjustment in utctimetuple() could produce
++ tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
++ cases.
++
++- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
++ directive. When the ``%z`` directive is present in the format string, an
++ aware ``datetime`` object is returned with ``tzinfo`` bound to a
++ ``datetime.timezone`` instance constructed from the parsed offset. If both
++ ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
++ name, but ``%Z`` data without ``%z`` is discarded.
++
++- Issue #5094: The ``datetime`` module now has a simple concrete class
++ implementing ``datetime.tzinfo`` interface. Instances of the new class,
++ ``datetime.timezone``, return fixed name and UTC offset from their
++ ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
++ returns ``None``. A class attribute, ``utc`` contains an instance
++ representing the UTC timezone. Original patch by Rafe Kaplan.
++
++- Issue #8973: Add __all__ to struct module; this ensures that help(struct)
++ includes documentation for the struct.Struct class.
++
++- Issue #3129: Trailing digits in struct format string are no longer ignored.
++ For example, "1" or "ilib123" are now invalid formats and cause
++ ``struct.error`` to be raised. Patch by Caleb Deveraux.
++
++- Issue #7384: If the system readline library is linked against ncurses, the
++ curses module must be linked against ncurses as well. Otherwise it is not safe
++ to load both the readline and curses modules in an application.
++
++- Issue #2810: Fix cases where the Windows registry API returns ERROR_MORE_DATA,
++ requiring a re-try in order to get the complete result.
++
++- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
++ with an improved 'binary-split' algorithm that uses fewer multiplications and
++ allows many of the multiplications to be performed using plain C integer
++ arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
++ arguments.
++
++- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
++ overflow checks in the audioop module.
++
++- Issue #8644: The accuracy of td.total_seconds() has been improved (by
++ calculating with integer arithmetic instead of float arithmetic internally):
++ the result is now always correctly rounded, and is equivalent to ``td /
++ timedelta(seconds=1)``.
++
++- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /
++ timedelta, timedelta % timedelta, timedelta // timedelta and divmod(timedelta,
++ timedelta) are all supported.
++
++- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
++
++- Issue #8300: When passing a non-integer argument to struct.pack with any
++ integer format code, struct.pack first attempts to convert the non-integer
++ using its __index__ method. If that method is non-existent or raises
++ TypeError it goes on to try the __int__ method, as described below.
++
++- Issue #8142: Update libffi to the 3.0.9 release.
++
++- Issue #6949: Allow the _dbm extension to be built with db 4.8.x.
++
++- Issue #6544: Fix a reference leak in the kqueue implementation's error
++ handling.
++
++- Stop providing crtassem.h symbols when compiling with Visual Studio 2010, as
++ msvcr100.dll is not a platform assembly anymore.
++
++- Issue #6508: Add posix.{getresuid,getresgid,setresuid,setresgid}.
++
++- Issue #7078: Set struct.__doc__ from _struct.__doc__.
++
++- Issue #3366: Add erf, erfc, expm1, gamma, lgamma functions to math module.
++
++- Issue #6877: It is now possible to link the readline extension to the libedit
++ readline emulation on OSX 10.5 or later.
++
++- Issue #6848: Fix curses module build failure on OS X 10.6.
++
++- Fix a segfault that could be triggered by expat with specially formed input.
++
++- Issue #6561: '\d' in a regex now matches only characters with Unicode category
++ 'Nd' (Number, Decimal Digit). Previously it also matched characters with
++ category 'No'.
++
++- Issue #4509: Array objects are no longer modified after an operation failing
++ due to the resize restriction in-place when the object has exported buffers.
++
++- Issue #2389: Array objects are now pickled in a portable manner.
++
++- Expat: Fix DoS via XML document with malformed UTF-8 sequences
++ (CVE_2009_3560).
++
++- Issue #7242: On Solaris 9 and earlier calling os.fork() from within a thread
++ could raise an incorrect RuntimeError about not holding the import lock. The
++ import lock is now reinitialized after fork.
++
++- Issue #7999: os.setreuid() and os.setregid() would refuse to accept a -1
++ parameter on some platforms such as OS X.
++
++- Build the ossaudio extension on GNU/kFreeBSD.
++
++- Issue #7347: winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in
++ the return value of QueryReflectionKey.
++
++- Issue #7567: PyCurses_setupterm: Don't call ``setupterm`` twice.
++
++Build
++-----
++
++- Use OpenSSL 1.0.0a on Windows.
++
++- Issue #9280: Make sharedinstall depend on sharedmods.
++
++- Issue #9189: Make a user-specified CFLAGS, CPPFLAGS, or LDFLAGS setting
++ override the configure and makefile defaults, without deleting options the
++ user didn't intend to override. Developers should no longer need to specify
++ OPT or EXTRA_CFLAGS, although those variables are still present for
++ backward-compatibility.
++
++- Issue #8854: Fix finding Visual Studio 2008 on Windows x64.
++
++- Issue #1759169, #8864: Drop _XOPEN_SOURCE on Solaris, define it for
++ multiprocessing only.
++
++- Issue #8625: Turn off optimization in --with-pydebug builds with gcc.
++ (Optimization was unintentionally turned on in gcc --with-pydebug builds as a
++ result of the issue #1628484 fix, combined with autoconf's strange choice of
++ default CFLAGS produced by AC_PROG_CC for gcc.)
++
++- Issue #3646: It is now easily possible to install a Python framework into your
++ home directory on MacOSX, see Mac/README for more information.
++

++ tests from compileall.
++
++- Issue #3920, #7903: Define _BSD_SOURCE on OpenBSD 4.4 through 4.9.
++
++- Issue #7632: When Py_USING_MEMORY_DEBUGGER is defined, disable the private
++ memory allocation scheme in dtoa.c and use PyMem_Malloc and PyMem_Free
++ instead. Also disable caching of powers of 5.
++
++- Issue #6491: Allow --with-dbmliborder to specify that no dbms will be built.
++
++- Issue #6943: Use pkg-config to find the libffi headers when the
++ --with-system-ffi flag is used.
++
++- Issue #7609: Add a --with-system-expat option that causes the system's expat
++ library to be used for the pyexpat module instead of the one included with
++ Python.
++
++- Issue #7589: Only build the nis module when the correct header files are
++ found.
++
++- Switch to OpenSSL 0.9.8l and sqlite 3.6.21 on Windows.

++- Issue #6802: Fix build issues on MacOSX 10.6.
++
++- Issue #6244: Allow detect_tkinter to look for Tcl/Tk 8.6.

++- python-config now supports multiple options on the same command line.
++
++- Issue #8509: Fix quoting in help strings and code snippets in configure.in.
++
++- Issue #8510: Update to autoconf2.65.

++
++Tests
++-----

++ import lock was disabled.
++
++- Issue #8605: Skip test_gdb if Python is compiled with optimizations.
++
++- Issue #7449: Skip test_socketserver if threading support is disabled.
++
++- Issue #8672: Add a zlib test ensuring that an incomplete stream can be handled
++ by a decompressor object without errors (it returns incomplete uncompressed
++ data).
++
++- Issue #8533: regrtest uses backslashreplace error handler for stdout to avoid
++ UnicodeEncodeError (write non-ASCII character to stdout using ASCII encoding).
++
++- Issue #8576: Remove use of find_unused_port() in test_smtplib and
++ test_multiprocessing. Patch by Paul Moore.

++ with no arguments, doctest.py now gives a usage message.
++
++- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
++
++- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
++ instead of a hardcoded port number in test_rapid_restart.
++
++- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
++ in the Lib/test directory, which might be read-only for the user running the
++ tests.
++
++- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
++ of an option with no handler.
++
++- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
++ fails. Can be combined with -j.
++
++- Issue #6551: test_zipimport could import and then destroy some modules of the
++ encodings package, which would make other tests fail further down the road
++ because the internally cached encoders and decoders would point to empty
++ global variables.
++
++- Issue #7295: Do not use a hardcoded file name in test_tarfile.
++
++- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
++ primitives such as Lock, RLock, Condition, Event and Semaphore.
++
++- Issue #7248 (part 2): Use a unique temporary directory for importlib source
++ tests instead of tempfile.tempdir. This prevents the tests from sharing state
++ between concurrent executions on the same system.
++
++- Issue #7248: In importlib.test.source.util a try/finally block did not make
++ sure that some referenced objects actually were created in the block before
++ calling methods on the object.
++
++- Issue #7222: Make thread "reaping" more reliable so that reference
++ leak-chasing test runs give sensible results. The previous method of reaping
++ threads could return successfully while some Thread objects were still
++ referenced. This also introduces a new private function:
++ ``_thread._count()``.
++
++- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
++ runs the risk of causing the worker thread to fail.
++
++- Issue #7055: test___all__ now greedily detects all modules which have an
++ __all__ attribute, rather than using a hardcoded and incomplete list.
++
++- Issue #7058: Added save/restore for things like sys.argv and cwd to
++ runtest_inner in regrtest, with warnings if the called test modifies them, and
++ a new section in the summary report at the end.
++
++- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
++
++- Fixed tests in importlib.test.source.test_abc_loader that were masking the
++ proper exceptions that should be raised for missing or improper code object
++ bytecode.
++
++- Removed importlib's custom test discovery code and switched to
++ unittest.TestLoader.discover().
++
++Tools/Demos
++-----------
++
++- Issue #5464, #8974: Implement plural forms in msgfmt.py.
++
++- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
++ added to the `Tools/` directory. They were previously living in the sandbox.
++

++ the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
++
++Library
++-------
++
++- Issue #6438: Fixed distutils.cygwinccompiler.get_versions : the regular

++ TimedRotatingFileHandler.
++
++- Issue #6217: The C implementation of io.TextIOWrapper didn't include the

++ are always None now.
++
++- Issue #6137: The pickle module now translates module names when loading
++ or dumping pickles with a 2.x-compatible protocol, in order to make data
++ sharing and migration easier. This behaviour can be disabled using the
++ new `fix_imports` optional argument.
++
++- Removed the ipaddr module.
++
++- Issue #3613: base64.{encode,decode}string are now called
++ base64.{encode,decode}bytes which reflects what type they accept and return.

++ --with-pydebug, and vice-versa.
++
++
++Build
++-----
++
++- Issue #6154: Make sure the intl library is added to LIBS if needed. Also
++ added LIBS to OS X framework builds.
++
++- Issue #5809: Specifying both --enable-framework and --enable-shared is

++
++
++
++What's New in Python 3.1 release candidate 1?
++=============================================
++
++*Release date: 2009-05-30*
++
++Core and Builtins
++-----------------
++
++- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
++ of the command line.
++
++- Issue #6012: Add cleanup support to O& argument parsing.
++
++- Issue #6089: Fixed str.format with certain invalid field specifiers
++ that would raise SystemError.
++
++- Issue #5982: staticmethod and classmethod now expose the wrapped
++ function with __func__.
++
++- Added support for multiple context managers in the same with-statement.
++ Deprecated contextlib.nested() which is no longer needed.
++
++- Issue #5829: complex("1e500") no longer raises OverflowError. This
++ makes it consistent with float("1e500") and interpretation of real
++ and imaginary literals.
++
++- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
++
++- Issue #5994: the marshal module now has docstrings.
++
++- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
++ (1) inf and nan strings with trailing whitespace were incorrectly
++ rejected; (2) parsing of strings representing infinities and nans
++ was locale aware; and (3) the interpretation of fromhex('-nan')
++ didn't match that of float('-nan').
++
++Library
++-------
++
++- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
++
++- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
++
++- Issue #6121: pydoc now ignores leading and trailing spaces in the
++ argument to the 'help' function.
++
++- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
++ arguments for strings with a space in them.
++
++- collections.namedtuple() was not working with the following field
++ names: cls, self, tuple, itemgetter, and property.
++
++- In unittest, using a skipping decorator on a class is now equivalent to
++ skipping every test on the class. The ClassTestSuite class has been removed.
++
++- Issue #6050: Don't fail extracting a directory from a zipfile if
++ the directory already exists.
++
++- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
++ than an int, which makes some operations possible under 64-bit Linux (e.g.
++ DN_MULTISHOT with F_NOTIFY).
++
++- Issue #5761: Add the name of the underlying file to the repr() of various
++ IO objects.
++
++- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
++ by Musashi Tamura, tests by Marcin Bachry.
++
++- Issue #1983: Fix functions taking or returning a process identifier to use
++ the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
++ a process identifier type wider than the standard C integer type.
++
++- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
++ Patch by Farhan Ahmad, test by Marcin Bachry.
++
++- Issue #2116: Weak references and weak dictionaries now support copy()ing and
++ deepcopy()ing.
++
++- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
++
++- Issue #5918: Fix a crash in the parser module.
++
++- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
++
++- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
++ library. This means, for example, that opening an UTF-16 text file in
++ append mode doesn't add a BOM at the end of the file if the file isn't
++ empty.
++
++- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
++ file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
++ corrects a pydoc regression.
++
++- Issue #5955: aifc's close method did not close the file it wrapped,
++ now it does. This also means getfp method now returns the real fp.
++
++Installation
++------------
++
++- Issue #6047: fullinstall has been removed because Python 3's executable will
++ now be known as python3.
++
++- Lib/smtpd.py is no longer installed as a script.
++
++Extension Modules
++-----------------
++
++- Issue #3061: Use wcsftime for time.strftime where available.
++
++- Issue #4873: Fix resource leaks in error cases of pwd and grp.
++
++- Issue #6093: Fix off-by-one error in locale.strxfrm.
++
++- The _functools and _locale modules are now built into the libpython shared
++ library instead of as extension modules.
++
++Build
++-----
++
++- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
++ and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
++ Clinton Roy.
++
++Tests
++-----
++
++- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
++ tests on darwin even when the OS was installed on a case-sensitive
++ filesystem. Also fixed tests that should not be run when
++ sys.dont_write_bytecode is true.
++
++
++What's New in Python 3.1 beta 1?
++================================
++
++*Release date: 2009-05-06*
++
++Core and Builtins
++-----------------
++
++- Issue #5914: Add new C API function PyOS_string_to_double, and
++ deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
++
++- Issue #3382: float.__format__, complex.__format__, and %-formatting
++ no longer map 'F' to 'f'. Because of issue #5859 (below), this only
++ affects nan -> NAN and inf -> INF.
++
++- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
++ in all operations, including splitdrive, split, etc. splitunc() now issues
++ a PendingDeprecation warning.
++
++- Issue #5920: For float.__format__, change the behavior with the
++ empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
++ to be like 'g' but with at least one decimal point and with a
++ default precision of 12. Previously, the behavior the same but with
++ a default precision of 6. This more closely matches str(), and
++ reduces surprises when adding alignment flags to the empty
++ presentation type. This also affects the new complex.__format__ in
++ the same way.
++
++- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
++
++- Issue #5890: in subclasses of 'property' the __doc__ attribute was
++ shadowed by classtype's, even if it was None. property now
++ inserts the __doc__ into the subclass instance __dict__.
++
++- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
++ sequences. Patch by Nick Barnes and Victor Stinner.
++
++- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
++
++- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
++ received a new method, detach(). detach() disconnects the underlying stream
++ from the buffer or text IO and returns it.
++
++- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
++ floats with absolute value over 1e50. Also remove length
++ restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
++ 12.34 no longer raise an exception.
++
++- Issue #1588: Add complex.__format__. For example,
++ format(complex(1, 2./3), '.5') now produces a sensible result.
++
++- Issue #5864: Fix empty format code formatting for floats so that it
++ never gives more than the requested number of significant digits.
++
++- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
++ new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
++
++- Issue #5835: Deprecate PyOS_ascii_formatd.
++
++- Issue #4971: Fix titlecase for characters that are their own
++ titlecase, but not their own uppercase.
++
++- Issue #5283: Setting __class__ in __del__ caused a segfault.
++
++- Issue #5816: complex(repr(z)) now recovers z exactly, even when
++ z involves nans, infs or negative zeros.
++
++- Issue #3166: Make int -> float conversions correctly rounded.
++
++- Issue #1869 (and many duplicates): make round(x, n) correctly
++ rounded for a float x, by using the decimal <-> binary conversions
++ from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
++ consistently agrees with format(x, '.2f').
++
++- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
++ some builtin types.
++
++- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
++
++- Issue #5515: str.format() type 'n' combined with commas and leading
++ zeros no longer gives odd results with ints and floats.
++
++- Implement PEP 378, Format Specifier for Thousands Separator, for
++ floats.
++
++- The str function switches to exponential notation at
++ 1e11, not 1e12. This avoids printing 13 significant digits in
++ situations where only 12 of them are correct. Example problem
++ value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
++ long time.)
++
++- Issue #1580: On most platforms, use a 'short' float repr: for a
++ finite float x, repr(x) now outputs a string based on the shortest
++ sequence of decimal digits that rounds to x. Previous behaviour was
++ to output 17 significant digits and then strip trailing zeros.
++ Another minor difference is that the new repr switches to
++ exponential notation at 1e16 instead of the previous 1e17; this
++ avoids misleading output in some cases.
++
++ There's a new sys attribute sys.float_repr_style, which takes
++ the value 'short' to indicate that we're using short float repr,
++ and 'legacy' if the short float repr isn't available for one
++ reason or another.
++
++ The float repr change involves incorporating David Gay's 'perfect
++ rounding' code into the Python core (it's in Python/dtoa.c). As a
++ secondary consequence, all string-to-float and float-to-string
++ conversions (including all float formatting operations) will be
++ correctly rounded on these platforms.
++
++ See issue #1580 discussions for details of platforms for which
++ this change does not apply.
++
++- Issue #5759: float() didn't call __float__ on str subclasses.
++
++- The string.maketrans() function is deprecated; there is a new static method
++ maketrans() on the bytes and bytearray classes. This removes confusion about
++ the types string.maketrans() is supposed to work with, and mirrors the
++ methods available on the str class.
++
++- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
++ its clarity and its speed.
++
++- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
++ to avoid compiler warnings.
++
++- Issue #3739: The unicode-internal encoder now reports the number of characters
++ consumed like any other encoder (instead of the number of bytes).
++
++Installation
++------------
++
++- Issue #5756: Install idle and pydoc with a 3 suffix.
++
++Library
++-------
++
++- Issue #8203: Fix IDLE Credits dialog: view_file() uses its encoding argument.

++- Issue #5311: bdist_msi can now build packages that do not depend on a
++ specific Python version.
++
++- Issue #5150: IDLE's format menu now has an option to strip trailing
++ whitespace.
++
++- Issue #5940: distutils.command.build_clib.check_library_list was not doing
++ the right type checkings anymore.

++
++- Issue #1309567: Fix linecache behavior of stripping subdirectories when
++ looking for files given by a relative filename.
++
++- Issue #5923: Update the ``turtle`` module to version 1.1, add two new
++ turtle demos in Demo/turtle.
++
++- Issue #5692: In ``zipfile.Zipfile``, fix wrong path calculation when
++ extracting a file to the root directory.
++
++- Issue #5913: os.listdir() should fail for empty path on windows.
++
++- Issue #5084: unpickling now interns the attribute names of pickled objects,
++ saving memory and avoiding growth in size of subsequent pickles. Proposal
++ and original patch by Jake McGuire.
++
++- The json module now works exclusively with str and not bytes.
++
++- Issue #3959: The ipaddr module has been added to the standard library.
++ Contributed by Google.
++
++- Issue #3002: ``shutil.copyfile()`` and ``shutil.copytree()`` now raise an
++ error when a named pipe is encountered, rather than blocking infinitely.
++
++- Issue #5857: tokenize.tokenize() now returns named tuples.
++
++- Issue #4305: ctypes should now build again on mipsel-linux-gnu
++
++- Issue #1734234: Massively speedup ``unicodedata.normalize()`` when the
++ string is already in normalized form, by performing a quick check beforehand.
++ Original patch by Rauli Ruohonen.
++
++- Issue #5853: calling a function of the mimetypes module from several threads
++ at once could hit the recursion limit if the mimetypes database hadn't been
++ initialized before.
++
++- Issue #5854: Updated __all__ to include some missing names and remove some
++ names which should not be exported.
++
++- Issue #3102: All global symbols that the _ctypes extension defines
++ are now prefixed with 'Py' or '_ctypes'.
++
++- Issue #5041: ctypes does now allow pickling wide character.
++
++- Issue #5812: For the two-argument form of the Fraction constructor,
++ Fraction(m, n), m and n are permitted to be arbitrary Rational
++ instances.
++
++- Issue #5812: Fraction('1e6') is valid: more generally, any string
++ that's valid for float() is now valid for Fraction(), with the
++ exception of strings representing NaNs and infinities.
++
++- Issue #5734: BufferedRWPair was poorly tested and had several glaring
++ bugs. Patch by Brian Quinlan.
++
++- Issue #1161031: fix readwrite select flag handling: POLLPRI now
++ results in a handle_expt_event call, not handle_read_event, and POLLERR
++ and POLLNVAL now call handle_close, not handle_expt_event. Also,
++ dispatcher now has an 'ignore_log_types' attribute for suppressing
++ log messages, which is set to 'warning' by default.
++
++- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
++ new arguments introduced in 2.5.
++
++- Issue #5828 (Invalid behavior of unicode.lower): Fixed bogus logic in
++ makeunicodedata.py and regenerated the Unicode database (This fixes
++ u'\u1d79'.lower() == '\x00').
++
++Extension Modules
++-----------------
++
++- Issue #5881: Remove old undocumented compatibility interfaces in hashlib and
++ pwd.
++
++- Issue #5463: In struct module, remove deprecated float coercion
++ for integer type codes: struct.pack('L', 0.3) should now raise
++ an error. The _PY_STRUCT_FLOAT_COERCE constant has been removed.
++ The version number has been bumped to 0.3.
++
++- Issue #5359: Readd the Berkeley DB detection code to allow _dbm be built
++ using Berkeley DB.
++
++Tests
++-----
++
++- Issue #5354: New test support function import_fresh_module() makes
++ it easy to import both normal and optimised versions of modules.
++ test_heapq and test_warnings have been adjusted to use it, tests for
++ other modules with both C and Python implementations in the stdlib
++ can be adjusted to use it over time.
++
++- Issue #5837: Certain sequences of calls to set() and unset() for
++ support.EnvironmentVarGuard objects restored the environment variables
++ incorrectly on __exit__.
++
++C-API
++-----
++

++
++
++What's New in Python 3.1 alpha 2?
++=================================
++
++*Release date: 2009-4-4*
++
++Core and Builtins
++-----------------
++
++- Implement PEP 378, Format Specifier for Thousands Separator, for
++ integers.
++
++- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
++
++- Issue #5499: The 'c' code for argument parsing functions now only accepts a
++ byte, and the 'C' code only accepts a unicode character.
++
++- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
++ when hitting the recursion limit under certain circumstances.
++
++- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
++
++- Fix a segfault when running test_exceptions with coverage, caused by
++ insufficient checks in accessors of Exception.__context__.
++
++- Issue #5604: non-ASCII characters in module name passed to
++ imp.find_module() were converted to UTF-8 while the path is
++ converted to the default filesystem encoding, causing nonsense.
++
++- Issue #5126: str.isprintable() returned False for space characters.
++
++- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
++ the end sys.path, for compatibility with the system install of Python.
++
++- Issue #4688: Add a heuristic so that tuples and dicts containing only
++ untrackable objects are not tracked by the garbage collector. This can
++ reduce the size of collections and therefore the garbage collection overhead
++ on long-running programs, depending on their particular use of datatypes.
++
++- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
++ improve its performance. Long divisions and remainder operations
++ are now between 50% and 150% faster.
++
++- Issue #4258: Make it possible to use base 2**30 instead of base
++ 2**15 for the internal representation of integers, for performance
++ reasons. Base 2**30 is enabled by default on 64-bit machines. Add
++ --enable-big-digits option to configure, which overrides the
++ default. Add sys.int_info structseq to provide information about
++ the internal format.
++
++- Issue #4474: PyUnicode_FromWideChar now converts characters outside
++ the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
++ and sizeof(Py_UNICODE) == 2.
++
++- Issue #5237: Allow auto-numbered fields in str.format(). For
++ example: '{} {}'.format(1, 2) == '1 2'.
++
++- Issue #5392: when a very low recursion limit was set, the interpreter would
++ abort with a fatal error after the recursion limit was hit twice.
++
++- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
++ short file names.
++
++Library
++-------
++
++- Issue #2625: added missing items() call to the for loop in
++ mailbox.MH.get_message().
++
++- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
++ error substitutions from non-strict codec error callbacks in
++ incrementalencoder and StreamWriter.
++
++- Issue #5656: Fix the coverage reporting when running the test suite with
++ the -T argument.
++
++- Issue #5647: MutableSet.__iand__() no longer mutates self during iteration.
++
++- Issue #5624: Fix the _winreg module name still used in several modules.
++
++- Issue #5628: Fix io.TextIOWrapper.read() with a unreadable buffer.
++
++- Issue #5619: Multiprocessing children disobey the debug flag and causes
++ popups on windows buildbots. Patch applied to work around this issue.
++
++- Issue #5400: Added patch for multiprocessing on netbsd compilation/support
++
++- Issue #5387: Fixed mmap.move crash by integer overflow.
++
++- Issue #5261: Patch multiprocessing's semaphore.c to support context
++ manager use: "with multiprocessing.Lock()" works now.
++
++- Issue #5236: Change time.strptime() to only take strings. Didn't work with
++ bytes already but the failure was non-obvious.
++
++- Issue #5177: Multiprocessing's SocketListener class now uses
++ socket.SO_REUSEADDR on all connections so that the user no longer needs
++ to wait 120 seconds for the socket to expire.
++
++- Issue #5595: Fix UnboundedLocalError in ntpath.ismount().
++
++- Issue #1174606: Calling read() without arguments of an unbounded file
++ (typically /dev/zero under Unix) could crash the interpreter.

++- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
++ io.BufferedRandom have been deprecated for removal in Python 3.2.
++
++- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
++ forever on incomplete input. That caused tarfile.open() to hang when used
++ with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
++ partial bzip2 compressed data.
++
++- Issue #2110: Add support for thousands separator and 'n' type
++ specifier to Decimal.__format__
++
++- Fix Decimal.__format__ bug that swapped the meanings of the '<' and
++ '>' alignment characters.
++
++- The error detection code in FileIO.close() could fail to reflect the `errno`
++ value, and report it as -1 instead.
++
++- Issue #5016: FileIO.seekable() could return False if the file position
++ was negative when truncated to a C int. Patch by Victor Stinner.
++
++Extension Modules
++-----------------
++
++- Issue #5391: mmap now deals exclusively with bytes.
++
++- Issue #5463: In struct module, remove deprecated overflow wrapping
++ when packing an integer: struct.pack('=L', -1) now raises
++ struct.error instead of returning b'\xff\xff\xff\xff'. The
++ _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
++ have been removed from the struct module.
++
++
++What's New in Python 3.1 alpha 1
++================================
++
++*Release date: 2009-03-07*
++
++Core and Builtins
++-----------------
++
++- The io module has been reimplemented in C for speed.
++
++- Give dict views an informative __repr__.
++
++- Issue #5247: Improve error message when unknown format codes are
++ used when using str.format() with str, int, and float arguments.
++
++- Issue #5249: time.strftime returned malformed string when format string
++ contained non ascii character on windows.
++
++- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
++ source has already been decoded into str.
++
++- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
++ rotating the object pointer by 4 bits to the right.
++
++- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
++ it now forces its argument to double before testing for infinity.
++
++- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
++ returns a non-number type.
++
++- Issue #5182: Removed memoryview.__str__.
++
++- Issue #1717: Removed builtin cmp() function, dropped tp_compare
++ slot, the C API functions PyObject_Compare and PyUnicode_Compare and
++ the type definition cmpfunc. The tp_compare slot has been renamed
++ to tp_reserved, and is reserved for future usage.
++
++- Issue #1242657: the __len__() and __length_hint__() calls in several tools
++ were suppressing all exceptions. These include list() and bytearray().
++
++- Issue #4707: round(x, n) now returns an integer if x is an integer.
++ Previously it returned a float.
++
++- Issue #4753: By enabling a configure option named '--with-computed-gotos'
++ on compilers that support it (notably: gcc, SunPro, icc), the bytecode
++ evaluation loop is compiled with a new dispatch mechanism which gives
++ speedups of up to 20%, depending on the system, on various benchmarks.
++
++- Issue #4874: Most builtin decoders now reject unicode input.
++
++- Issue #4842: Don't allow trailing 'L' when constructing an integer
++ from a string.
++
++- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
++
++- Issue #4838: When a module is deallocated, free the memory backing the
++ optional module state data.
++
++- Issue #4910: Rename nb_long slot to nb_reserved, and change its
++ type to ``(void *)``.
++
++- Issue #4935: The overflow checking code in the expandtabs() method common
++ to str, bytes and bytearray could be optimized away by the compiler, letting
++ the interpreter segfault instead of raising an error.
++
++- Issue #3720: Fix a crash when an iterator modifies its class and removes its
++ __next__ method.
++
++- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
++ function no longer attempt to call the __long__ slot to convert an object
++ to an integer. Only the __int__ and __trunc__ slots are examined.
++
++- Issue #4893: Use NT threading on CE.
++
++- Issue #4915: Port sysmodule to Windows CE.
++
++- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
++ common cases are optimized thanks to a dedicated fast path and a moderate
++ amount of loop unrolling.
++
++- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
++ collecting the oldest generation) so that allocating lots of objects without
++ destroying them does not show quadratic performance. Based on a proposal by
++ Martin von Löwis at
++ http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
++
++- Issue #4604: Some objects of the I/O library could still be used after
++ having been closed (for instance, a read() call could return some
++ previously buffered data). Patch by Dmitry Vasiliev.
++
++- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
++ flag to work properly. Furthermore, when specifying -u, the text stdout
++ and stderr streams have line-by-line buffering enabled (the default being
++ to buffer arbitrary chunks of data).
++
++- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
++ instead of ints (reducing its size from 4 to 8 times thereby reducing
++ Python's overall memory).
++
++- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
++ an existing .py counterpart, override the co_filename attributes of all
++ code objects if the original filename is obsolete (which can happen if the
++ file has been renamed, moved, or if it is accessed through different paths).
++ Patch by Ziga Seilnacht and Jean-Paul Calderone.
++
++- Issue #4580: Fix slicing of memoryviews when the item size is greater than
++ one byte. Also fixes the meaning of len() so that it returns the number of
++ items, rather than the size in bytes.
++
++- Issue #4075: Use OutputDebugStringW in Py_FatalError.
++
++- Issue #4747: When the terminal does not use utf-8, executing a script with
++ non-ascii characters in its name could fail with a "SyntaxError: None" error.
++
++- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
++ to open file with a bytes filename on Windows.
++
++- Issue #3680: Reference cycles created through a dict, set or deque iterator
++ did not get collected.
++
++- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
++ where the tp_hash and tp_dict slots are both NULL.
++
++- Issue #4759: None is now allowed as the first argument of
++ bytearray.translate(). It was always allowed for bytes.translate().
++
++- Added test case to ensure attempts to read from a file opened for writing
++ fail.
++
++- Issue #3106: Speedup some comparisons (str/str and int/int).
++
++- Issue #2183: Simplify and optimize bytecode for list, dict and set
++ comprehensions. Original patch for list comprehensions by Neal Norwitz.
++
++- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
++ print elapsed times, not only when some objects are uncollectable /
++ unreachable. Original patch by Neil Schemenauer.
++
++- Issue #3439: Add a bit_length method to int.
++
++- Issue #2173: When getting device encoding, check that return value of
++ nl_langinfo is not the empty string. This was causing silent build
++ failures on OS X.
++
++- Issue #4597: Fixed several opcodes that weren't always propagating
++ exceptions.
++
++- Issue #4589: Fixed exception handling when the __exit__ function of a
++ context manager returns a value that cannot be converted to a bool.
++
++- Issue #4445: Replace "sizeof(PyBytesObject)" with
++ "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
++ bytes instances. On a typical machine this saves 3 bytes of memory
++ (on average) per allocation of a bytes instance.
++
++- Issue #4533: File read operation was dreadfully slow due to a slowly
++ growing read buffer. Fixed by using the same growth rate algorithm as
++ Python 2.x.
++
++- Issue #4509: Various issues surrounding resize of bytearray objects to
++ which there are buffer exports (e.g. memoryview instances).
++
++- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
++ method on file objects with closefd=False. The file descriptor is still
++ kept open but the file object behaves like a closed file. The ``FileIO``
++ object also got a new readonly attribute ``closefd``.
++
++- Issue #4569: Interpreter crash when mutating a memoryview with an item size
++ larger than 1.
++
++- Issue #4748: Lambda generators no longer return a value.
++
++- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
++
++- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
++ PyUnicode_DecodeUTF8() once, remember the result and output it in a second
++ step. This avoids problems with counting UTF-8 bytes that ignores the effect
++ of using the replace error handler in PyUnicode_DecodeUTF8().
++

++ collections.namedtuple() relied on __name__ being defined.
++
++- Backport importlib from Python 3.1. Only the import_module() function has
++ been backported to help facilitate transitions from 2.7 to 3.1.

++ be disabled, and not compiled.
++
++- Issue #5008: When a file is opened in append mode with the new IO library,
++ do an explicit seek to the end of file (so that e.g. tell() returns the
++ file size rather than 0). This is consistent with the behaviour of the
++ traditional 2.x file object.
++
++- Issue #5013: Fixed a bug in FileHandler which occurred when the delay
++ parameter was set.
++
++- Issue #4842: Always append a trailing 'L' when pickling longs using

++ in sharedctypes.py.
++
++- Issue #1225107: inspect.isclass() returned True for instances with a custom
++ __getattr__.
++
++- Issue #3826 and #4791: The socket module now closes the underlying socket
++ appropriately when it is being used via socket.makefile() objects
++ rather than delaying the close by waiting for garbage collection to do it.

++ the timestamp in the gzip stream. The default value remains the current time.
++ The information can be used by e.g. gunzip when decompressing. Patch by
++ Jacques Frechet.

++
++- Issue #3638: Remove functions from _tkinter module level that depend on

++- Issue #4812: add missing underscore prefix to some internal-use-only
++ constants in the decimal module. (Dec_0 becomes _Dec_0, etc.)
++
++- Issue #4790: The nsmallest() and nlargest() functions in the heapq module
++ did unnecessary work in the common case where no key function was specified.
++
++- Issue #4795: inspect.isgeneratorfunction() returns False instead of None when
++ the function is not a generator.
++
++- Issue #4702: Throwing a DistutilsPlatformError instead of IOError in case
++ no MSVC compiler is found under Windows. Original patch by Philip Jenvey.
++
++- Issue #4646: distutils was choking on empty options arg in the setup

++
++- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
++
++- Issue #4738: Each zlib object now has a separate lock, allowing to compress

++What's New in Python 3.3.1?
++===========================
++
++*Not yet released, see sections below for changes released in 3.3.0*
++
++.. *Release date: XX-XXX-2012*
++
++Core and Builtins
++-----------------
++
++- Issue #7963: Fixed misleading error message that issued when object is
++ called without arguments.
++
++- Issue #5308: Raise ValueError when marshalling too large object (a sequence
++ with size >= 2**31), instead of producing illegal marshal data.
++
++- Issue #12983: Bytes literals with invalid \x escape now raise a SyntaxError
++ and a full traceback including line number.
++
++- Issue #17173: Remove uses of locale-dependent C functions (isalpha() etc.)
++ in the interpreter.
++
++- Issue #17137: When an Unicode string is resized, the internal wide character
++ string (wstr) format is now cleared.
++
++- Issue #17043: The unicode-internal decoder no longer read past the end of
++ input buffer.
++
++- Issue #17098: All modules now have __loader__ set even if they pre-exist the
++ bootstrapping of importlib.
++
++- Issue #16979: Fix error handling bugs in the unicode-escape-decode decoder.
++
++- Issue #10156: In the interpreter's initialization phase, unicode globals
++ are now initialized dynamically as needed.

++- Issue #16980: Fix processing of escaped non-ascii bytes in the
++ unicode-escape-decode decoder.
++
++- Issue #16975: Fix error handling bug in the escape-decode bytes decoder.
++
++- Issue #14850: Now a charmap decoder treats U+FFFE as "undefined mapping"
++ in any mapping, not only in a string.
++
++- Issue #16730: importlib.machinery.FileFinder now no longers raises an
++ exception when trying to populate its cache and it finds out the directory is
++ unreadable or has turned into a file. Reported and diagnosed by
++ David Pritchard.
++
++- Issue #16906: Fix a logic error that prevented most static strings from being
++ cleared.
++
++- Issue #11461: Fix the incremental UTF-16 decoder. Original patch by

++ ASCII/surrogateescape codec is now used, instead of the locale encoding, to
++ decode the command line arguments. This change fixes inconsistencies with
++ os.fsencode() and os.fsdecode() because these operating systems announces an
++ ASCII locale encoding, whereas the ISO-8859-1 encoding is used in practice.
++
++- Issue #16761: Calling int() with base argument only now raises TypeError.
++
++- Issue #16759: Support the full DWORD (unsigned long) range in Reg2Py

++ chain, the object could remain reachable through its weakref even though
++ its refcount had dropped to zero.
++
++- Issue #16416: On Mac OS X, operating system data are now always
++ encoded/decoded to/from UTF-8/surrogateescape, instead of the locale encoding
++ (which may be ASCII if no locale environment variable is set), to avoid
++ inconsistencies with os.fsencode() and os.fsdecode() functions which are
++ already using UTF-8/surrogateescape.

++- Issue #15144: Fix possible integer overflow when handling pointers as integer
++ values, by using `Py_uintptr_t` instead of `size_t`. Patch by Serhiy
++ Storchaka.
++
++- Issue #15965: Explicitly cast `AT_FDCWD` as (int). Required on Solaris 10
++ (which defines `AT_FDCWD` as ``0xffd19553``), harmless on other platforms.
++
++- Issue #15839: Convert SystemErrors in `super()` to RuntimeErrors.
++
++- Issue #15846: Fix SystemError which happened when using `ast.parse()` in an
++ exception handler on code with syntax errors.
++
++- Issue #15801: Make sure mappings passed to '%' formatting are actually
++ subscriptable.
++
++- Issue #15111: __import__ should let ImportError propagate when a module that
++ is imported as a side-effect of using fromlist tries to import a module
++ that cannot be found.

+-
+-- Issue #5871: email.header.Header.encode now raises an error if any

+- like a header. Since Generator uses Header to format all headers, this check
+- is made for all headers in any serialized message at serialization time. This

+- private by renaming it to ``_GeneratorContextManager``.
+-

+- when it is invoked directly as the __main__ module.
+-
+-- `python -m test` can be used to run the test suite as well as `python -m
+- test.regrtest`.
+-
+-- Do not fail test_socket when the IP address of the local hostname cannot be
+- looked up.

+-What's New in Python 3.2 Alpha 4?
+-=================================
+-
+-*Release date: 13-Nov-2010*
+-
+-Core and Builtins

+-- Issue #10372: Import the warnings module only after the IO library is
+- initialized, so as to avoid bootstrap issues with the '-W' option.

+- undocumented value PyBUF_SHADOW, and strangely-looking code in
+- PyMemoryView_GetContiguous.

+-
+-- If FileIO.__init__ fails, close the file descriptor.

+-
+-- Issue #10186: Fix the SyntaxError caret when the offset is equal to the length

+-
+-- Issue #4388: On Mac OS X, decode command line arguments from UTF-8, instead of
+- the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment
+- variable is not set, the locale encoding is ISO-8859-1, whereas most programs
+- (including Python) expect UTF-8. Python already uses UTF-8 for the filesystem
+- encoding and to encode command line arguments on this OS.
+-
+-- Issue #9713, #10114: Parser functions (e.g. PyParser_ASTFromFile) expect
+- filenames encoded to the filesystem encoding with the surrogateescape error
+- handler (to support undecodable bytes), instead of UTF-8 in strict mode.
+-
+-- Issue #9997: Don't let the name "top" have special significance in scope
+- resolution.

+-- Issue #10386: Add __all__ to token module; this simplifies importing in
+- tokenize module and prevents leaking of private names through ``import *``.
+-
+-- Issue #4471: Properly shutdown socket in IMAP.shutdown(). Patch by Lorenzo
+- M. Catucci.
+-
+-- Fix IMAP.login() to work properly.
+-
+-- Issue #9244: multiprocessing pool worker processes could terminate
+- unexpectedly if the return value of a task could not be pickled. Only the
+- ``repr`` of such errors are now sent back, wrapped in an
+- ``MaybeEncodingError`` exception.
+-
+-- Issue #9244: The ``apply_async()`` and ``map_async()`` methods of
+- ``multiprocessing.Pool`` now accepts a ``error_callback`` argument. This can
+- be a callback with the signature ``callback(exc)``, which will be called if
+- the target raises an exception.
+-
+-- Issue #10022: The dictionary returned by the ``getpeercert()`` method of SSL
+- sockets now has additional items such as ``issuer`` and ``notBefore``.
+-
+-- ``usenetrc`` is now false by default for NNTP objects.
+-
+-- Issue #1926: Add support for NNTP over SSL on port 563, as well as STARTTLS.
+- Patch by Andrew Vant.
+-
+-- Issue #10335: Add tokenize.open(), detect the file encoding using
+- tokenize.detect_encoding() and open it in read only mode.
+-
+-- Issue #10321: Add support for binary data to smtplib.SMTP.sendmail, and a new
+- method send_message to send an email.message.Message object.
+-
+-- Issue #6011: sysconfig and distutils.sysconfig use the surrogateescape error
+- handler to parse the Makefile file. Avoid a UnicodeDecodeError if the source
+- code directory name contains a non-ASCII character and the locale encoding is
+- ASCII.
+-
+-- Issue #10329: The trace module writes reports using the input Python script
+- encoding, instead of the locale encoding. Patch written by Alexander
+- Belopolsky.

+-
+-- Issue #10311: The signal module now restores errno before returning from its
+- low-level signal handler. Patch by Hallvard B Furuseth.
+-
+-- Issue #10282: Add a ``nntp_implementation`` attribute to NNTP objects.
+-
+-- Issue #10283: Add a ``group_pattern`` argument to NNTP.list().
+-
+-- Issue #10155: Add IISCGIHandler to wsgiref.handlers to support IIS CGI
+- environment better, and to correct unicode environment values for WSGI 1.0.1.
+-
+-- Issue #10281: nntplib now returns None for absent fields in the OVER/XOVER
+- response, instead of raising an exception.
+-
+-- wsgiref now implements and validates PEP 3333, rather than an experimental
+- extension of PEP 333. (Note: earlier versions of Python 3.x may have
+- incorrectly validated some non-compliant applications as WSGI compliant; if
+- your app validates with Python <3.2b1+, but not on this version, it is likely
+- the case that your app was not compliant.)
+-
+-- Issue #10280: NNTP.nntp_version should reflect the highest version advertised
+- by the server.
+-
+-- Issue #10184: Touch directories only once when extracting a tarfile.
+-

+- append that isn't seekable. Patch by Brian Brazil.
+-
+-- Support context manager protocol for file-like objects returned by mailbox

+- access via file:// scheme.
+-
+-- Issue #1710703: Write structures for an empty ZIP archive when a ZipFile is
+- created in modes 'a' or 'w' and then closed without adding any files. Raise
+- BadZipfile (rather than IOError) when opening small non-ZIP files.
+-
+-- Issue #10041: The signature of optional arguments in socket.makefile() didn't
+- match that of io.open(), and they also didn't get forwarded properly to
+- TextIOWrapper in text mode. Patch by Kai Zhu.

+-
+-What's New in Python 3.2 Alpha 3?
+-=================================
+-
+-*Release date: 09-Oct-2010*
+-
+-Core and Builtins
+------------------
+-
+-- Issue #10068: Global objects which have reference cycles with their module's
+- dict are now cleared again. This causes issue #7140 to appear again.
+-
+-- Issue #9738: Document PyErr_SetString() and PyErr_SetFromErrnoWithFilename()
+- encodings.
+-
+-- ast.literal_eval() can now handle negative numbers. It is also a little more
+- liberal in what it accepts without compromising the safety of the evaluation.
+- For example, 3j+4 and 3+4+5 are both accepted.
+-
+-- Issue #10006: type.__abstractmethods__ now raises an AttributeError. As a
+- result metaclasses can now be ABCs (see #9533).
+-
+-- Issue #8670: ctypes.c_wchar supports non-BMP characters with 32 bits wchar_t.
+-
+-- Issue #8670: PyUnicode_AsWideChar() and PyUnicode_AsWideCharString() replace
+- UTF-16 surrogate pairs by single non-BMP characters for 16 bits Py_UNICODE and
+- 32 bits wchar_t (eg. Linux in narrow build).
+-
+-- Issue #10003: Allow handling of SIGBREAK on Windows. Fixes a regression
+- introduced by issue #9324.
+-
+-- Issue #9979: Create function PyUnicode_AsWideCharString().
+-
+-- Issue #7397: Mention that importlib.import_module() is probably what someone
+- really wants to be using in __import__'s docstring.
+-
+-- Issue #8521: Allow CreateKeyEx, OpenKeyEx, and DeleteKeyEx functions of winreg
+- to use named arguments.
+-
+-- Issue #9930: Remove bogus subtype check that was causing (e.g.)
+- float.__rdiv__(2.0, 3) to return NotImplemented instead of the expected 1.5.
+-
+-- Issue #9808: Implement os.getlogin for Windows. Patch by Jon Anglin.
+-
+-- Issue #9901: Destroying the GIL in Py_Finalize() can fail if some other
+- threads are still running. Instead, reinitialize the GIL on a second call to
+- Py_Initialize().
+-
+-- All SyntaxErrors now have a column offset and therefore a caret when the error
+- is printed.
+-
+-- Issue #9252: PyImport_Import no longer uses a fromlist hack to return the
+- module that was imported, but instead gets the module from sys.modules.
+-
+-- Issue #9213: The range type_items now provides index() and count() methods, to
+- conform to the Sequence ABC. Patch by Daniel Urban and Daniel Stutzbach.
+-
+-- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
+- with a non-empty format string. This is an effort to future-proof user
+- code. If a derived class does not currently implement __format__ but later
+- adds its own __format__, it would most likely break user code that had
+- supplied a format string. This will be changed to a DeprecationWaring in
+- Python 3.3 and it will be an error in Python 3.4.
+-
+-- Issue #9828: Destroy the GIL in Py_Finalize(), so that it gets properly
+- re-created on a subsequent call to Py_Initialize(). The problem (a crash)
+- wouldn't appear in 3.1 or 2.7 where the GIL's structure is more trivial.
+-
+-- Issue #9210: Configure option --with-wctype-functions was removed. Using the
+- functions from the libc caused the methods .upper() and lower() to become
+- locale aware and created subtly wrong results.
+-
+-- Issue #9738: PyUnicode_FromFormat() and PyErr_Format() raise an error on a
+- non-ASCII byte in the format string.
+-
+-- Issue #4617: Previously it was illegal to delete a name from the local
+- namespace if it occurs as a free variable in a nested block. This limitation
+- of the compiler has been lifted, and a new opcode introduced (DELETE_DEREF).
+-
+-- Issue #9804: ascii() now always represents unicode surrogate pairs as a single
+- ``\UXXXXXXXX``, regardless of whether the character is printable or not.
+- Also, the "backslashreplace" error handler now joins surrogate pairs into a
+- single character on UCS-2 builds.
+-
+-- Issue #9757: memoryview objects get a release() method to release the
+- underlying buffer (previously this was only done when deallocating the
+- memoryview), and gain support for the context management protocol.
+-
+-- Issue #9797: pystate.c wrongly assumed that zero couldn't be a valid
+- thread-local storage key.
+-
+-Library
+--------
+-
+-- Issue #2236: distutils' mkpath ignored the mode parameter.
+-
+-- Fix typo in one sdist option (medata-check).
+-
+-- Issue #9199: Fix incorrect use of distutils.cmd.Command.announce.
+-
+-- Issue #1718574: Fix options that were supposed to accept arguments but did
+- not in build_clib.
+-
+-- Issue #9437: Fix building C extensions with non-default LDFLAGS.
+-
+-- Issue #4661: email can now parse bytes input and generate either converted
+- 7bit output or bytes output. Email version bumped to 5.1.0.
+-
+-- Issue #1589: Add ssl.match_hostname(), to help implement server identity
+- verification for higher-level protocols.
+-
+-- Issue #9759: GzipFile now raises ValueError when an operation is attempted
+- after the file is closed. Patch by Jeffrey Finkelstein.
+-
+-- Issue #9042: Fix interaction of custom translation classes and caching in
+- gettext.
+-
+-- Issue #6706: asyncore.dispatcher now provides a handle_accepted() method
+- returning a (sock, addr) pair which is called when a connection has been
+- established with a new remote endpoint. This is supposed to be used as a
+- replacement for old handle_accept() and avoids the user to call accept()
+- directly.
+-
+-- Issue #9065: tarfile no longer uses "root" as the default for the uname and
+- gname field.
+-
+-- Issue #8980: Fixed a failure in distutils.command check that was shadowed by
+- an environment that does not have docutils. Patch by Arfrever.
+-
+-- Issue #1050268: parseaddr now correctly quotes double quote and backslash
+- characters that appear inside quoted strings in email addresses.
+-
+-- Issue #10004: quoprimime no longer generates a traceback when confronted with
+- invalid characters after '=' in a Q-encoded word.
+-
+-- Issue #1491: BaseHTTPServer nows send a ``100 Continue`` response before
+- sending a 200 OK for the Expect: 100-continue request header.
+-
+-- Issue #9360: Cleanup and improvements to the nntplib module. The API now
+- conforms to the philosophy of bytes and unicode separation in Python 3. A
+- test suite has also been added.
+-
+-- Issue #9962: GzipFile now has the peek() method.
+-
+-- Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,
+- retry the select() loop instead of bailing out. This is because select() can
+- incorrectly report a socket as ready for reading (for example, if it received
+- some data with an invalid checksum).
+-
+-- Issue #3612: Added new types to ctypes.wintypes. (CHAR and pointers)
+-
+-- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
+- received. Now sendall() properly calls signal handlers if necessary, and
+- retries sending if these returned successfully, including on sockets with a
+- timeout.
+-
+-- Issue #9947: logging: Fixed locking bug in stopListening.
+-
+-- Issue #9945: logging: Fixed locking bugs in addHandler/removeHandler.
+-
+-- Issue #9936: Fixed executable lines' search in the trace module.
+-
+-- Issue #9790: Rework imports necessary for samefile and sameopenfile
+- in ntpath.
+-
+-- Issue #9928: Properly initialize the types exported by the bz2 module.
+-
+-- Issue #1675951: Allow GzipFile to work with unseekable file objects. Patch by
+- Florian Festi.
+-
+-- Logging: Added QueueListener class to facilitate logging usage for
+- performance-critical threads.
+-
+-- Issue #9916: Add some missing errno symbols.
+-
+-- Issue #9877: Expose sysconfig.get_makefile_filename()
+-
+-- logging: Added hasHandlers() method to Logger and LoggerAdapter.
+-
+-- Issue #9908: Fix os.stat() on bytes paths under Windows 7.
+-
+-- Issue #2643: msync() is not called anymore when deallocating an open mmap
+- object, only munmap().
+-
+-- logging: Changed LoggerAdapter implementation internally, to make it easier to
+- subclass in a useful way.
+-
+-- logging: hasHandlers method was added to Logger, and isEnabledFor,
+- getEffectiveLevel, hasHandlers and setLevel were added to LoggerAdapter.
+- LoggerAdapter was introduced into the unit tests for logging.
+-
+-- Issue #1686: Fix string.Template when overriding the pattern attribute.
+-
+-- Issue #9854: SocketIO objects now observe the RawIOBase interface in
+- non-blocking mode: they return None when an operation would block (instead of
+- raising an exception).
+-
+-- Issue #1730136: Fix the comparison between a tk.font.Font and an object of
+- another kind.
+-
+-- Issue #9441: logging has better coverage for rotating file handlers.
+-
+-- Issue #9865: collections.OrderedDict now has a __sizeof__ method.
+-
+-- Issue #9854: The default read() implementation in io.RawIOBase now handles
+- non-blocking readinto() returning None correctly.
+-
+-- Issue #1552: socket.socketpair() now returns regular socket.socket objects
+- supporting the whole socket API (rather than the "raw" _socket.socket
+- objects).
+-
+-- Issue #9853: Fix the signature of SSLSocket.recvfrom() and SSLSocket.sendto()
+- to match the corresponding socket methods.
+-
+-- Issue #9840: Added a decorator to reprlib for wrapping __repr__ methods to make
+- them handle recursive calls within the same thread.
+-
+-- logging: Enhanced HTTPHandler with secure and credentials initializers.
+-
+-- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
+-
+-- Issue #9837: The read() method of ZipExtFile objects (as returned by
+- ZipFile.open()) could return more bytes than requested.
+-
+-- Issue #9826: OrderedDict.__repr__ can now handle self-referential values:
+- d['x'] = d.
+-
+-- Issue #9825: Using __del__ in the definition of collections.OrderedDict made
+- it possible for the user to create self-referencing ordered dictionaries which
+- become permanently uncollectable GC garbage. Reinstated the Python 3.1
+- approach of using weakref proxies so that reference cycles never get created
+- in the first place.
+-
+-- Issue #9579, #9580: Fix os.confstr() for value longer than 255 bytes and
+- encode the value with filesystem encoding and surrogateescape (instead of
+- utf-8 in strict mode) . Patch written by David Watson.
+-
+-- Issue #9632: Remove sys.setfilesystemencoding() function: use PYTHONFSENCODING
+- environment variable to set the filesystem encoding at Python startup.
+- sys.setfilesystemencoding() creates inconsistencies because it is unable to
+- reencode all filenames in all objects.
+-
+-- Issue #9410: Various optimizations to the pickle module, leading to speedups
+- up to 4x (depending on the benchmark). Mostly ported from Unladen Swallow;
+- initial patch by Alexandre Vassalotti.
+-
+-- The pprint module now supports printing OrderedDicts in their given order
+- (formerly, it would sort the keys).
+-
+-- Logging: Added QueueHandler class to facilitate logging usage with
+- multiprocessing.
+-
+-- Issue #9707: Rewritten reference implementation of threading.local which is
+- friendlier towards reference cycles. This change is not normally visible
+- since an optimized C implementation (_thread._local) is used instead.
+-
+-- Issue #6394: os.getppid() is now supported on Windows. Note that it will
+- still return the id of the parent process after it has exited. This process
+- id may even have been reused by another unrelated process.
+-
+-- Issue #9792: In case of connection failure, socket.create_connection() would
+- swallow the exception and raise a new one, making it impossible to fetch the
+- original errno, or to filter timeout errors. Now the original error is
+- re-raised.
+-
+-- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True, and
+- the passed buffer was exactly 1024 bytes long, the buffer wouldn't be updated
+- back after the system call. Original patch by Brian Brazil.
+-
+-- Updates to the random module:
+-
+- * Document which parts of the module are guaranteed to stay the same across
+- versions and which parts are subject to change.
+-
+- * Update the seed() method to use all of the bits in a string instead of just
+- the hash value. This makes better use of the seed value and assures the
+- seeding is platform independent. Issue #7889.
+-
+- * Improved the random()-->integer algorithm used in choice(), shuffle(),
+- sample(), randrange(), and randint(). Formerly, it used int(n*random())
+- which has a slight bias whenever n is not a power of two. Issue #9025.
+-
+- * Improved documentation of arguments to randrange(). Issue #9379.
+-
+-- collections.OrderedDict now supports a new method for repositioning keys to
+- either end.
+-
+-- Issue #9754: Similarly to assertRaises and assertRaisesRegexp, unittest test
+- cases now also have assertWarns and assertWarnsRegexp methods to check that a
+- given warning type was triggered by the code under test.
+-
+-- Issue #5506: BytesIO objects now have a getbuffer() method exporting a view of
+- their contents without duplicating them. The view is both readable and
+- writable.
+-
+-- Issue #7566: Implement os.path.sameopenfile for Windows.
+-
+-- Issue #9293: I/O streams now raise ``io.UnsupportedOperation`` when an
+- unsupported operation is attempted (for example, writing to a file open only
+- for reading).
+-
+-- hashlib has two new constant attributes: algorithms_guaranteed and
+- algorithms_avaiable that respectively list the names of hash algorithms
+- guaranteed to exist in all Python implementations and the names of hash
+- algorithms available in the current process.
+-
+-- A new package ``concurrent.futures`` as defined by PEP 3148.
+-
+-C-API
+------
+-
+-- Add PyErr_SyntaxLocationEx, which supports passing a column offset.
+-
+-- Issue #9834: Don't segfault in PySequence_GetSlice, PySequence_SetSlice, or
+- PySequence_DelSlice when the object doesn't have any mapping operations
+- defined.
+-
+-Tools/Demos
+------------
+-
+-- Issue #9188: The gdb extension now handles correctly narrow (UCS2) as well as
+- wide (UCS4) unicode builds for both the host interpreter (embedded inside gdb)
+- and the interpreter under test.
+-
+-Tests
+------
+-
+-- Issue #9308: Added tests for importing encoded modules that do not
+- depend on specific stdlib modules being encoded in a certain way.
+-
+-- Issue #1051: Add a script (Lib/test/make_ssl_certs.py) to generate the custom
+- certificate and private key files used by SSL-related certs.
+-
+-- Issue #9978: Wait until subprocess completes initialization. (Win32KillTests
+- in test_os)
+-
+-- Issue #7110: regrtest now sends test failure reports and single-failure
+- tracebacks to stderr rather than stdout.
+-
+-- Issue #9628: fix runtests.sh -x option so more than one test can be excluded.
+-
+-- Issue #9899: Fix test_tkinter.test_font on various platforms. Patch by Ned
+- Deily.
+-
+-- Issue #9894: Do not hardcode ENOENT in test_subprocess.
+-
+-- Issue #9315: Added tests for the trace module. Patch by Eli Bendersky.
+-
+-- Issue #9323: Make test.regrtest.__file__ absolute, this was not always the
+- case when running profile or trace, for example.
+-
+-- Issue #9568: Fix test_urllib2_localnet on OS X 10.3.
+-
+-Build
+------
+-
+-- Issue #10062: Allow building on platforms which do not have sem_timedwait.
+-
+-- Issue #10054: Some platforms provide uintptr_t in inttypes.h. Patch by Akira
+- Kitada.
+-
+-- Issue #10055: Make json C89-compliant in UCS4 mode.
+-
+-- Issue #9552: Avoid unnecessary rebuild of OpenSSL. (Windows)
+-
+-- Issue #1633863: Don't ignore $CC under AIX.
+-
+-- Issue #9810: Compile bzip2 source files in Python's project file directly. It
+- used to be built with bzip2's makefile.
+-
+-- Issue #9848: Stopping trying to build _weakref in setup.py as it is a built-in
+- module.
+-
+-- Issue #9806: python-config now has an ``--extension-suffix`` option that
+- outputs the suffix for dynamic libraries including the ABI version name
+- defined by PEP 3149.
+-
+-- Issue #941346: Improve the build process under AIX and allow Python to be
+- built as a shared library. Patch by Sébastien Sablé.
+-
+-- Issue #4026: Make the fcntl extension build under AIX. Patch by Sébastien
+- Sablé.
+-
+-- Issue #9701: The MacOSX installer can patch the shell profile to ensure that
+- the "bin" directory inside the framework is on the shell's search path. This
+- feature now also supports the ZSH shell.
+-
+-
+-What's New in Python 3.2 Alpha 2?
+-=================================
+-
+-*Release date: 05-Sep-2010*
+-
+-Core and Builtins
+------------------
+-
+-- Issue #9225: Remove the ROT_FOUR and DUP_TOPX opcode, the latter replaced by
+- the new (and simpler) DUP_TOP_TWO. Performance isn't changed, but our
+- bytecode is a bit simplified. Patch by Demur Rumed.
+-
+-- Issue #9766: Rename poorly named variables exposed by _warnings to prevent
+- confusion with the proper variables names from 'warnings' itself.
+-
+-- Issue #9212: dict_keys and dict_items now provide the isdisjoint() method, to
+- conform to the Set ABC. Patch by Daniel Urban.
+-
+-- Issue #9737: Fix a crash when trying to delete a slice or an item from a
+- memoryview object.
+-
+-- Issue #9549: sys.setdefaultencoding() and PyUnicode_SetDefaultEncoding() are
+- now removed, since their effect was inexistent in 3.x (the default encoding is
+- hardcoded to utf-8 and cannot be changed).
+-
+-- Issue #7415: PyUnicode_FromEncodedObject() now uses the new buffer API
+- properly. Patch by Stefan Behnel.
+-
+-- Issue #5553: The Py_LOCAL_INLINE macro now results in inlining on most
+- platforms. Previously, it inlined only when using Microsoft Visual C.
+-
+-- Issue #9712: Fix tokenize on identifiers that start with non-ascii names.
+-
+-- Issue #9688: __basicsize__ and __itemsize__ must be accessed as Py_ssize_t.
+-
+-- Issue #9684: Added a definition for SIZEOF_WCHAR_T to PC/pyconfig.h, to match
+- the pyconfig.h generated by configure on other systems.
+-
+-- Issue #9666: Only catch AttributeError in hasattr(). All other exceptions that
+- occur during attribute lookup are now propagated to the caller.
+-
+-- Issue #8622: Add PYTHONFSENCODING environment variable to override the
+- filesystem encoding.
+-
+-- Issue #5127: The C functions that access the Unicode Database now accept and
+- return characters from the full Unicode range, even on narrow unicode builds
+- (Py_UNICODE_TOLOWER, Py_UNICODE_ISDECIMAL, and others). A visible difference
+- in Python is that unicodedata.numeric() now returns the correct value for
+- large code points, and repr() may consider more characters as printable.
+-
+-- Issue #9425: Create PyModule_GetFilenameObject() function to get the filename
+- as a unicode object, instead of a byte string. Function needed to support
+- unencodable filenames. Deprecate PyModule_GetFilename() in favor on the new
+- function.
+-
+-- Issue #8063: Call _PyGILState_Init() earlier in Py_InitializeEx().
+-
+-- Issue #9612: The set object is now 64-bit clean under Windows.
+-
+-- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when searching for
+- the module file to be executed with the -m command line option.
+-
+-- Issue #9599: Create PySys_FormatStdout() and PySys_FormatStderr() functions to
+- write a message formatted by PyUnicode_FromFormatV() to sys.stdout and
+- sys.stderr.
+-
+-- Issue #9542: Create PyUnicode_FSDecoder() function, a ParseTuple converter:
+- decode bytes objects to unicode using PyUnicode_DecodeFSDefaultAndSize(); str
+- objects are output as-is.
+-
+-- Issue #9203: Computed gotos are now enabled by default on supported compilers
+- (which are detected by the configure script). They can still be disable
+- selectively by specifying --without-computed-gotos.
+-
+-- Issue #9425: Create PyErr_WarnFormat() function, similar to PyErr_WarnEx() but
+- use PyUnicode_FromFormatV() to format the warning message.
+-
+-- Issue #8530: Prevent stringlib fastsearch from reading beyond the front of an
+- array.
+-
+-- Issue #5319: Print an error if flushing stdout fails at interpreter shutdown.
+-
+-- Issue #9337: The str() of a float or complex number is now identical to its
+- repr().
+-
+-- Issue #9416: Fix some issues with complex formatting where the output with no
+- type specifier failed to match the str output:
+-
+- - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
+- - format(complex(0.0, 2.0), '-') included a sign and parentheses.

+-- Issue #8013: time.asctime and time.ctime no longer call system
+- asctime and ctime functions. The year range for time.asctime is now

+- by the server. Many servers are buggy and advertise authentication methods
+- they do not support in reality.
+-
+-- Issue #8814: function annotations (the ``__annotations__`` attribute) are now

+-
+-What's New in Python 3.2 Alpha 1?
+-=================================
+-
+-*Release date: 01-Aug-2010*
+-
+-Core and Builtins
+------------------
+-
+-- Issue #8991: convertbuffer() rejects discontigious buffers.
+-
+-- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
+- compiler.
+-
+-- Issue #8413: structsequence now subclasses tuple.
+-
+-- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
+- start byte and the continuation byte(s) are now considered invalid, instead of
+- the number of bytes specified by the start byte. E.g.:
+- '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and replaces
+- with U+FFFD only the start byte ('\xf1') and the continuation byte ('\x80')
+- even if '\xf1' is the start byte of a 4-bytes sequence. Previous versions
+- returned a single u'\ufffd'.
+-
+-- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real part -0.0
+- rather than 0.0. So "-7j" is now exactly equivalent to "-(7j)".
+-
+-- Be more specific in error messages about positional arguments.
+-
+-- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
+- objects, as described in the documentation.
+-
+-- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
+- Fix the encoding of the modules filename. Patch written by Amaury Forgeot
+- d'Arc.
+-
+-- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST compilation code
+- dealing with unary minus applied to a constant. The removed code was mutating
+- the ST, causing a second compilation to fail.
+-
+-- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
+- mode raises unicode errors. The encoder only supports "strict" and "replace"
+- error handlers, the decoder only supports "strict" and "ignore" error
+- handlers. Patch written by Mark Hammond.
+-
+-- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
+- "w*" format instead. Add tests for "w*" format.
+-
+-- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
+- formats if the string contains a null byte/character. Write unit tests for
+- string formats.
+-
+-- Issue #7490: To facilitate sharing of doctests between 2.x and 3.x test
+- suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
+- location of the raised exception.
+-
+-- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
+- filenames and enable os.fsencode().
+-
+-- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
+-
+-- Issue #8941: Decoding big endian UTF-32 data in UCS-2 builds could crash the
+- interpreter with characters outside the Basic Multilingual Plane (higher than
+- 0x10000).
+-
+-- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now raise
+- TypeError instead of giving a DeprecationWarning when a float is parsed using
+- the 'L' code (for long long). (All other integer codes already raise
+- TypeError in this case.)
+-
+-- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
+- enable shortcuts for upper case encoding name. Add also a shortcut for
+- "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
+-
+-- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
+- doesn't support "char buffer" anymore in Python 3.
+-
+-- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
+- instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
+- like bytearray.
+-
+-- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
+- used anymore and it was never documented.
+-
+-- In str.format(), raise a ValueError when indexes to arguments are too large.
+-
+-- Issue #2844: Make int('42', n) consistently raise ValueError for invalid
+- integers n (including n = -909).
+-
+-- Issue #8188: Introduce a new scheme for computing hashes of numbers (instances
+- of int, float, complex, decimal.Decimal and fractions.Fraction) that makes it
+- easy to maintain the invariant that hash(x) == hash(y) whenever x and y have
+- equal value.
+-
+-- Issue #8748: Fix two issues with comparisons between complex and integer
+- objects. (1) The comparison could incorrectly return True in some cases
+- (2**53+1 == complex(2**53) == 2**53), breaking transitivity of equality.
+- (2) The comparison raised an OverflowError for large integers, leading to
+- unpredictable exceptions when combining integers and complex objects in sets
+- or dicts.
+-
+-- Issue #8766: Initialize _warnings module before importing the first module.
+- Fix a crash if an empty directory called "encodings" exists in sys.path.
+-
+-- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
+- encoding and surrogateescape error handler instead of the locale encoding to
+- be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
+-
+-- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace (instead
+- of strict) error handler to escape surrogates.
+-
+-- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
+- object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
+- handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
+- back to UTF-8.
+-
+-- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
+- error handler, not only the default error handler (strict).
+-
+-- Issue #8610: Load file system codec at startup, and display a fatal error on
+- failure. Set the file system encoding to utf-8 (instead of None) if getting
+- the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
+-
+-- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
+- PyUnicode_FromString() to support surrogates in the filename and use the right
+- encoding.
+-
+-- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
+-
+-- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler.
+-
+-- Issue #8419: Prevent the dict constructor from accepting non-string keyword
+- arguments.
+-
+-- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
+- indirectly Python signal handlers anymore because mywrite() ignores exceptions
+- (KeyboardInterrupt).
+-
+-- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
+- unicode string (eg. backslashreplace).
+-
+-- Issue #8485: PyUnicode_FSConverter() doesn't accept byteearray objects
+- anymore, you have to convert your bytearray filenames to bytes.
+-
+-- Issue #7332: Remove the 16KB stack-based buffer in
+- PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable benefit
+- compared to the dynamic memory allocation fallback. Patch by Charles-François
+- Natali.
+-
+-- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
+- passed to bytes or bytearray.
+-
+-- Issue #7301: Add environment variable $PYTHONWARNINGS.
+-
+-- Issue #8329: Don't return the same lists from select.select when no fds are
+- changed.
+-
+-- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error' on
+- 64-bit machines. The shift count for either left or right shift is permitted
+- to be up to sys.maxsize.
+-
+-- Ensure that tokenization of identifiers is not affected by locale.
+-
+-- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
+-
+-- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
+-
+-- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
+- is set.
+-
+-- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
+- is unknown.
+-
+-- Issue #1583863: A str subclass can now override the __str__ method.
+-
+-- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
+- PyMemberDefs could produce an internal error; raise TypeError instead.
+-
+-- Issue #7845: Rich comparison methods on the complex type now return
+- NotImplemented rather than raising a TypeError when comparing with an
+- incompatible type; this allows user-defined classes to implement their own
+- comparisons with complex.
+-
+-- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
+- (SIGINT). If an error occurs while importing the site module, the error is
+- printed and Python exits. Initialize the GIL before importing the site module.
+-
+-- Issue #7173: Generator finalization could invalidate sys.exc_info().
+-
+-- Issue #7544: Preallocate thread memory before creating the thread to avoid a
+- fatal error in low memory condition.
+-
+-- Issue #7820: The parser tokenizer restores all bytes in the right if the BOM
+- check fails.
+-
+-- Handle errors from looking up __prepare__ correctly.
+-
+-- Issue #5939: Add additional runtime checking to ensure a valid capsule in
+- Modules/_ctypes/callproc.c.
+-
+-- Issue #7309: Fix unchecked attribute access when converting
+- UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to strings.
+-
+-- Issue #6902: Fix problem with built-in types format incorrectly with 0
+- padding.
+-
+-- Issue #7988: Fix default alignment to be right aligned for complex.__format__.
+- Now it matches other numeric types.
+-
+-- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
+- PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string and
+- PyOS_string_to_double instead. See issue #5835 for the original deprecations.
+-
+-- Issue #7385: Fix a crash in `MemoryView_FromObject` when `PyObject_GetBuffer`
+- fails. Patch by Florent Xicluna.
+-
+-- Issue #7788: Fix an interpreter crash produced by deleting a list slice with
+- very large step value.
+-
+-- Issue #7766: Change sys.getwindowsversion() return value to a named tuple and
+- add the additional members returned in an OSVERSIONINFOEX structure. The new
+- members are service_pack_major, service_pack_minor, suite_mask, and
+- product_type.
+-
+-- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`) could
+- crash in many places because of the PyByteArray_AS_STRING() macro returning
+- NULL. The macro now returns a statically allocated empty string instead.
+-
+-- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
+- where the right hand operand is a set of constants, by turning the set into a
+- frozenset and pre-building it as a constant. The comparison operation is made
+- against the constant instead of building a new set each time it is executed (a
+- similar optimization already existed which turned a list of constants into a
+- pre-built tuple). Patch and additional tests by Dave Malcolm.
+-
+-- Issue #7622: Improve the split(), rsplit(), splitlines() and replace() methods
+- of bytes, bytearray and unicode objects by using a common implementation based
+- on stringlib's fast search. Patch by Florent Xicluna.
+-
+-- Issue #7632: Fix various str -> float conversion bugs present in 2.7 alpha 2,
+- including: (1) a serious 'wrong output' bug that could occur for long (> 40
+- digit) input strings, (2) a crash in dtoa.c that occurred in debug builds when
+- parsing certain long numeric strings corresponding to subnormal values, (3) a
+- memory leak for some values large enough to cause overflow, and (4) a number
+- of flaws that could lead to incorrectly rounded results.
+-
+-- The __complex__ method is now looked up on the class of instances to make it
+- consistent with other special methods.
+-
+-- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
+- `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
+-
+-- Issue #7604: Deleting an unset slotted attribute did not raise an
+- AttributeError.
+-
+-- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
+- in ** operator. The behaviour now conforms to that described in C99 Annex F.
+-
+-- Issue #1811: improve accuracy and cross-platform consistency for true division
+- of integers: the result of a/b is now correctly rounded for ints a and b (at
+- least on IEEE 754 platforms), and in particular does not depend on the
+- internal representation of an int.
+-
+-- Issue #6834: replace the implementation for the 'python' and 'pythonw'
+- executables on OSX.
+-
+- These executables now work properly with the arch(1) command: ``arch -ppc
+- python`` will start a universal binary version of python in PPC mode (unlike
+- previous releases).
+-
+-- Issue #7466: Segmentation fault when the garbage collector is called in the
+- middle of populating a tuple. Patch by Florent Xicluna.
+-
+-- Issue #7419: setlocale() could crash the interpreter on Windows when called
+- with invalid values.
+-
+-- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
+- mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
+-
+-- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
+- 10.6.
+-
+-- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
+-
+-- Issue #6970: Remove redundant calls when comparing objects that don't
+- implement the relevant rich comparison methods.
+-
+-- Issue #7298: Fixes for range and reversed(range(...)). Iteration over
+- range(a, b, c) incorrectly gave an empty iterator when a, b and c fit in C
+- long but the length of the range did not. Also fix several cases where
+- reversed(range(a, b, c)) gave wrong results, and fix a refleak for
+- reversed(range(a, b, c)) with large arguments.
+-
+-- Issue #7244: itertools.izip_longest() no longer ignores exceptions raised
+- during the formation of an output tuple.
+-

+- libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
+- will be entirely removed in 3.3.
+-
+-- Support for OSF* has been disabled. If nobody stands up, support will be
+- removed in 3.3. See <http://bugs.python.org/issue8606>.
+-
+-- Peephole constant folding had missed UNARY_POSITIVE.
+-
+-- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

+- support.
+-
+-- Issue #7120: logging: Removed import of multiprocessing which is causing crash
+- in GAE.

+- should be no other effect than a small decrease in memory use. Patch by
+- Christopher Tur Lesniewski-Laas.
+-
+-- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when using
+- byte values greater than 127. Patch by Derk Drukker.
+-
+-- Issue #1571184: The Unicode database contains properties for more characters.
+- The tables for code points representing numeric values, white spaces or line
+- breaks are now generated from the official Unicode Character Database files,
+- and include information from the Unihan.txt file.
+-
+-- Issue #7019: Raise ValueError when unmarshalling bad long data, instead of
+- producing internally inconsistent Python longs.
+-
+-- Issue #6990: Fix threading.local subclasses leaving old state around after a

+-
+-- Issue #1616979: Added the cp720 (Arabic DOS) encoding.
+-
+-- Issue #6428: Since Python 3.0, the __bool__ method must return a bool object,
+- and not an int. Fix the corresponding error message, and the documentation.
+-
+-- The deprecated PyCObject has been removed.
+-
+-- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a

+- to construct a null-initialized bytes object.
+-
+-- Issue #1023290: Add from_bytes() and to_bytes() methods to integers. These
+- methods allow the conversion of integers to bytes, and vice-versa.
+-
+-- Issue #7382: Fix bug in bytes.__getnewargs__ that prevented bytes instances

+- properly.
+-
+-- Code objects now support weak references.
+-
+-- Issue #7072: isspace(0xa0) is true on Mac OS X.
+-
+-- Issue #8084: PEP 370 now conforms to system conventions for framework builds
+- on MacOS X. That is, "python setup.py install --user" will install into
+- "~/Library/Python/2.7" instead of "~/.local".
+-
+-C-API
+------
+-
+-- Issue #2443: A new macro, `Py_VA_COPY`, copies the state of the
+- variable argument list. `Py_VA_COPY` is equivalent to C99
+- `va_copy`, but available on all python platforms.
+-
+-- PySlice_GetIndicesEx now clips the step to [-PY_SSIZE_T_MAX, PY_SSIZE_T_MAX]
+- instead of [-PY_SSIZE_T_MAX-1, PY_SSIZE_T_MAX]. This makes it safe to do
+- "step = -step" when reversing a slice.
+-
+-- Issue #5753: A new C API function, `PySys_SetArgvEx`, allows embedders of the
+- interpreter to set sys.argv without also modifying sys.path. This helps fix
+- `CVE-2008-5983
+- <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
+-
+-- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
+- strings in an efficient manner.
+-
+-- Issue #8276: PyEval_CallObject() is now only available in macro form. The
+- function declaration, which was kept for backwards compatibility reasons, is
+- now removed (the macro was introduced in 1997!).
+-
+-- Issue #7767: New function PyLong_AsLongLongAndOverflow added, analogous to
+- PyLong_AsLongAndOverflow.
+-
+-- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
+- has '\0' at the end.
+-
+-- Issue #5080: The argument parsing functions PyArg_ParseTuple,
+- PyArg_ParseTupleAndKeywords, PyArg_VaParse, PyArg_VaParseTupleAndKeywords and
+- PyArg_Parse now raise a DeprecationWarning for float arguments passed with the
+- 'L' format code. This will become a TypeError in a future version of Python,
+- to match the behaviour of the other integer format codes.
+-
+-- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.
+-
+-- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments) in
+- PyArg_ParseTupleAndKeywords.
+-
+-- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V) and
+- PyErr_Format, on machines with HAVE_LONG_LONG defined.
+-
+-- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD in
+- PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be should used for
+- accessing the d_type and d_name members of structures using PyDescr_COMMON.
+-
+-- Issue #6405: Remove duplicate type declarations in descrobject.h.
+-
+-- The code flags for old __future__ features are now available again.
+-
+-- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
+- PyCode_Addr2Line().
+-

+- object at a specified file, function, and line number.
+-
+-- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
+- ``const char *`` as the string is stored beyond the call.
+-
+-- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
+- allocator will be automatically disabled when running under Valgrind. This
+- gives improved memory leak detection when running under Valgrind, while taking
+- advantage of pymalloc at other times.
+-
+-Library
+--------
+-
+-- In pdb, when Ctrl-C is entered while defining commands for a breakpoint, the
+- old commands are restored.
+-
+-- For traceback debugging, the pdb listing now also shows the locations where
+- the exception was originally (re)raised, if it differs from the last line
+- executed (e.g. in case of finally clauses).
+-
+-- The pdb command "source" has been added. It displays the source code for a
+- given object, if possible.
+-
+-- The pdb command "longlist" has been added. It displays the whole source code
+- for the current function.
+-
+-- Issue #1503502: Make pdb.Pdb easier to subclass by putting message and error
+- output into methods.

+- in .pdbrc.
+-
+-- Issue #4179: In pdb, allow "list ." as a command to return to the currently
+- debugged line.
+-
+-- Issue #4108: In urllib.robotparser, if there are multiple ``User-agent: *``
+- entries, consider the first one.

+- before ASCII-to-binary decoding.
+-
+-- Issue #9384: ``python -m tkinter`` will now display a simple demo applet.
+-
+-- The default size of the re module's compiled regular expression cache has been
+- increased from 100 to 500 and the cache replacement policy has changed from
+- simply clearing the entire cache on overflow to forgetting the least recently
+- used cached compiled regular expressions. This is a performance win for
+- applications that use a lot of regular expressions and limits the impact of
+- the performance hit anytime the cache is exceeded.
+-
+-- Issue #7113: Speed up loading in configparser. Patch by Åukasz Langa.
+-
+-- Issue #9032: XML-RPC client retries the request on EPIPE error. The EPIPE
+- error occurs when the server closes the socket and the client sends a big
+- XML-RPC request.
+-
+-- Issue #4629: getopt raises an error if an argument ends with "=", whereas
+- getopt doesn't accept a value (eg. --help= is rejected if getopt uses
+- ['help='] long options).
+-
+-- Issue #7989: Added pure python implementation of the `datetime` module. The C
+- module is renamed to `_datetime` and if available, overrides all classes
+- defined in datetime with fast C impementation. Python implementation is based
+- on the original python prototype for the datetime module by Tim Peters with
+- minor modifications by the PyPy project. The test suite now tests `datetime`
+- module with and without `_datetime` acceleration using the same test cases.
+-
+-- Issue #7895: platform.mac_ver() no longer crashes after calling os.fork().

+-
+-- Issue #7646: The fnmatch pattern cache no longer grows without bound.
+-
+-- Issue #9136: Fix 'dictionary changed size during iteration' RuntimeError
+- produced when profiling the decimal module. This was due to a dangerous
+- iteration over 'locals()' in Context.__init__.
+-
+-- Fix extreme speed issue in Decimal.pow when the base is an exact power of 10
+- and the exponent is tiny (for example, ``Decimal(10) **
+- Decimal('1e-999999999')``).
+-
+-- Issue #9186: Fix math.log1p(-1.0) to raise ValueError, not OverflowError.
+-
+-- Issue #9130: Fix validation of relative imports in parser module.
+-
+-- Issue #9128: Fix validation of class decorators in parser module.

+- Urban.
+-
+-- Issue #7829: Clearly document that the dis module is exposing an
+- implementation detail that is not stable between Python VMs or releases.
+-
+-- Issue #6589: cleanup asyncore.socket_map in case smtpd.SMTPServer constructor
+- raises an exception.
+-
+-- Issue #9110: Addition of ContextDecorator to contextlib, for creating APIs
+- that act as both context managers and decorators. contextmanager changes to
+- use ContextDecorator.
+-
+-- Implement importlib.abc.SourceLoader and deprecate PyLoader and PyPycLoader
+- for removal in Python 3.4.
+-
+-- Issue #9064: pdb's "up" and "down" commands now accept an optional argument
+- giving the number of frames to go.
+-
+-- Issue #9018: os.path.normcase() now raises a TypeError if the argument is not
+- ``str`` or ``bytes``.
+-
+-- Issue #9075: In the ssl module, remove the setting of a ``debug`` flag on an
+- OpenSSL structure.
+-
+-- Issue #8682: The ssl module now temporary increments the reference count of a
+- socket object got through ``PyWeakref_GetObject``, so as to avoid possible
+- deallocation while the object is still being used.
+-
+-- Issue #1368368: FancyURLOpener class changed to throw an Exception on wrong
+- password instead of presenting an interactive prompt. Older behavior can be
+- obtained by passing retry=True to http_error_xxx methods of FancyURLOpener.
+-
+-- Issue #8720: Fix regression caused by fix for #4050 by making getsourcefile
+- smart enough to find source files in the linecache.
+-
+-- Issue #5610: feedparser no longer eats extra characters at the end of a body

+-
+-- Issue #8784: Set tarfile default encoding to 'utf-8' on Windows.
+-
+-- Issue #8966: If a ctypes structure field is an array of c_char, convert its
+- value to bytes instead of str (as done for c_char and c_char_p).
+-
+-- Issue #8188: Comparisons between Decimal and Fraction objects are now
+- permitted, returning a result based on the exact numerical values of the
+- operands. This builds on issue #2531, which allowed Decimal-to-float
+- comparisons; all comparisons involving numeric types (bool, int, float,
+- complex, Decimal, Fraction) should now act as expected.

+- issue #1368247.
+-
+-- Issue #8845: sqlite3 Connection objects now have a read-only in_transaction
+- attribute that is True iff there are uncommitted changes.
+-

+- correspond to the decimal interchange formats specified in IEEE 754.
+-
+-- Issue #6268: Fix seek() method of codecs.open(), don't read or write the BOM
+- twice after seek(0). Fix also reset() method of codecs, UTF-16, UTF-32 and

+- correct encoding.
+-
+-- Issue #4870: Add an `options` attribute to SSL contexts, as well as several
+- ``OP_*`` constants to the `ssl` module. This allows to selectively disable
+- protocol versions, when used in combination with `PROTOCOL_SSLv23`.
+-
+-- Issue #8759: Fixed user paths in sysconfig for posix and os2 schemes.
+-
+-- Issue #8663: distutils.log emulates backslashreplace error handler. Fix

+- stdout is not a TTY).
+-
+-- Issue #8513: os.get_exec_path() supports b'PATH' key and bytes value.
+- subprocess.Popen() and os._execvpe() support bytes program name. Add

+- pax headers as described in POSIX.1-2008.
+-
+-- Issue #1285086: Speed up urllib.parse functions: quote, quote_from_bytes,
+- unquote, unquote_to_bytes.
+-
+-- Issue #8688: Distutils now recalculates MANIFEST everytime.
+-
+-- Issue #8477: ssl.RAND_egd() and ssl._test_decode_cert() support str with
+- surrogates and bytes for the filename.
+-

+- larger than 1GB with the zlib module's compressor and decompressor objects.
+-
+-- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
+- mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
+- file system encoding with the surrogateescape error handler (instead of

+-
+-- Issue #8573: asyncore _strerror() function might throw ValueError.
+-
+-- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error

+-
+-- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
+- Patch by Tres Seaver.

+-
+-- Issue #8621: uuid.uuid4() returned the same sequence of values in the parent
+- and any children created using ``os.fork`` on MacOS X 10.6.
+-
+-- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
+- operation raises multiple signals and more than one of those signals is
+- trapped, the specification determines the order in which the signals should be
+- handled. In many cases this order wasn't being followed, leading to the wrong
+- Python exception being raised.
+-
+-- Issue #7865: The close() method of ``io`` objects should not swallow
+- exceptions raised by the implicit flush(). Also qensure that calling close()
+- several times is supported. Patch by Pascal Chambon.

+- and mappings.
+-
+-- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
+- the method could block indefinitely if called just before the event loop
+- started running. This also fixes the occasional freezes witnessed in
+- test_httpservers.
+-
+-- Issue #8524: When creating an SSL socket, the timeout value of the original
+- socket wasn't retained (instead, a socket with a positive timeout would be
+- turned into a non-blocking SSL socket).
+-
+-- Issue #5103: SSL handshake would ignore the socket timeout and block
+- indefinitely if the other end didn't respond.
+-
+-- The do_handshake() method of SSL objects now adjusts the blocking mode of the
+- SSL structure if necessary (as other methods already do).
+-
+-- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates and
+- bytes strings for environment keys and values.
+-
+-- Issue #8467: Pure Python implementation of subprocess encodes the error
+- message using surrogatepass error handler to support surrogates in the
+- message.
+-
+-- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames.
+-
+-- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
+- string "python" as the *ident*. openlog() arguments are all optional and
+- keywords.
+-
+-- Issue #8108: Fix the unwrap() method of SSL objects when the socket has a
+- non-infinite timeout. Also make that method friendlier with applications
+- wanting to continue using the socket in clear-text mode, by disabling
+- OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
+-
+-- Issue #8496: make mailcap.lookup() always return a list, rather than an
+- iterator. Patch by Gregory Nofi.
+-
+-- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
+- collation name contains a surrogate character.
+-
+-- Issue #8484: Load all ciphers and digest algorithms when initializing the _ssl
+- extension, such that verification of some SSL certificates doesn't fail
+- because of an "unknown algorithm".
+-
+-- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
+-
+-- Issue #1540112: Now allowing the choice of a copy function in shutil.copytree.
+-
+-- Issue #4814: timeout parameter is now applied also for connections resulting
+- from PORT/EPRT commands.
+-
+-- Issue #8463: added missing reference to bztar in shutil's documentation.
+-
+-- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6 (as
+- long as the user didn't specify 'automatic proxy configuration').
+-
+-- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response code

+-- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
+-
+-- Issue #7316: The acquire() method of lock objects in the ``threading``
+- module now takes an optional timeout argument in seconds. Timeout support
+- relies on the system threading library, so as to avoid a semi-busy wait loop.
+-
+-- Issue #8383: pickle and pickletools use surrogatepass error handler when
+- encoding unicode as utf8 to support lone surrogates and stay compatible with
+- Python 2.x and 3.x.
+-
+-- Issue #7585: difflib context and unified diffs now place a tab between
+- filename and date, conforming to the 'standards' they were originally designed
+- to follow. This improves compatibility with patch tools.
+-
+-- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
+- character sets will now consistently use a Content-Transfer-Encoding of 7bit
+- rather than sometimes being marked as 8bit.
+-
+-- Issue #8375: test_distutils now checks if the temporary directory are still
+- present before it cleans them.
+-
+-- Issue #8374: Update the internal alias table in the ``locale`` module to
+- cover recent locale changes and additions.
+-
+-- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
+- using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
+- `ssl.OPENSSL_VERSION_NUMBER`.
+-
+-- Add functools.total_ordering() and functools.cmp_to_key().
+-
+-- Issue #8257: The Decimal construct now accepts a float instance directly,
+- converting that float to a Decimal of equal value:
+-
+- >>> Decimal(1.1)
+- Decimal('1.100000000000000088817841970012523233890533447265625')
+-
+-- Issue #8294: The Fraction constructor now accepts Decimal and float instances
+- directly.
+-

+- InvalidOperation instead of returning False. (Comparisons involving a quiet
+- NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
+- signaling NaNs remain unhashable.
+-
+-- Issue #2531: Comparison operations between floats and Decimal instances now
+- return a result based on the numeric values of the operands; previously they
+- returned an arbitrary result based on the relative ordering of id(float) and
+- id(Decimal). See also issue #8188, which adds Decimal-to-Fraction
+- comparisons.
+-
+-- Added a subtract() method to collections.Counter().
+-
+-- Issue #8233: When run as a script, py_compile.py optionally takes a single
+- argument `-` which tells it to read files to compile from stdin. Each line is
+- read on demand and the named file is compiled immediately. (Original patch by
+- Piotr Ożarowski).
+-
+-- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
+- form feed (0x0C) are now considered linebreaks, as specified in Unicode
+- Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
+-
+-- Comparisons using one of <, <=, >, >= between a complex instance and a
+- Fractions instance now raise TypeError instead of returning True/False. This
+- makes Fraction <=> complex comparisons consistent with int <=> complex, float
+- <=> complex, and complex <=> complex comparisons.
+-
+-- Issue #8139: ossaudiodev didn't initialize its types properly, therefore some
+- methods (such as oss_mixer_device.fileno()) were not available. Initial patch
+- by Bertrand Janin.
+-
+-- Issue #8205: Remove the "Modules" directory from sys.path when Python is
+- running from the build directory (POSIX only).
+-
+-- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
+- didn't support chflags() (for example ZFS under FreeBSD). The error is now
+- silenced.
+-
+-- Issue #7860: platform.uname now reports the correct 'machine' type when Python
+- is running in WOW64 mode on 64 bit Windows.
+-
+-- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
+- Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
+- reads and writes are always retried by OpenSSL itself.

+-
+-- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of the
+- locale.
+-
+-- The internals of the subprocess module on POSIX systems have been replaced by
+- an extension module (_posixsubprocess) so that the fork()+exec() can be done
+- safely without the possibility of deadlock in multithreaded applications.
+-
+-- subprocess.Popen now has restore_signals and start_new_session features. The
+- default of restore_signals=True is a new behavior compared to earlier Python
+- versions. This means that signals such as SIGPIPE are not ignored by default
+- in subprocesses launched by Python (Issue #1652).
+-
+-- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
+- cElementTree module is updated too.
+-

+-- Issue #6509: fix re.sub to work properly when the pattern, the string, and the
+- replacement were all bytes. Patch by Antoine Pitrou.

+-
+-- Issue #7633: In the decimal module, Context class methods (with the exception
+- of canonical and is_canonical) now accept instances of int and long wherever a
+- Decimal instance is accepted, and implicitly convert that argument to Decimal.
+- Previously only some arguments were converted.
+-
+-- Issue #7835: shelve should no longer produce mysterious warnings during
+- interpreter shutdown.
+-
+-- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in XML
+- processing instructions and comments. These raw characters are allowed by the
+- XML specification, and are necessary when outputting e.g. PHP code in a
+- processing instruction. Patch by Neil Muller.
+-
+-- Issue #6233: ElementTree failed converting unicode characters to XML entities
+- when they could't be represented in the requested output encoding. Patch by
+- Jerry Chen.
+-
+-- Issue #6003: add an argument to ``zipfile.Zipfile.writestr`` to specify the
+- compression type.
+-
+-- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
+- specified, rather than fall through to AF_PACKET (in the `socket` module).
+- Also, raise ValueError rather than TypeError when an unknown TIPC address type
+- is specified. Patch by Brian Curtin.
+-
+-- Issue #6939: Fix file I/O objects in the `io` module to keep the original file
+- position when calling `truncate()`. It would previously change the file
+- position to the given argument, which goes against the tradition of
+- ftruncate() and other truncation APIs. Patch by Pascal Chambon.
+-
+-- Issue #7610: Reworked implementation of the internal
+- ``zipfile.ZipExtFile`` class used to represent files stored inside an
+- archive. The new implementation is significantly faster and can be wrapped in
+- a ``io.BufferedReader`` object for more speedups. It also solves an
+- issue where interleaved calls to `read()` and `readline()` give wrong results.
+- Patch by Nir Aides.
+-
+-- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
+- allowing for a maximum number of tasks within the pool to be completed by the
+- worker before that worker is terminated, and a new one created to replace it.
+-
+-- Issue #7792: Registering non-classes to ABCs raised an obscure error.
+-

+- by Brian Curtin.
+-
+-- Issue #7681: Use floor division in appropiate places in the wave module.
+-
+-- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since
+- Extension extra options may change the output without changing the .c
+- file). Initial patch by Collin Winter.

+- parameter to allow specifying where your connections come from.
+-
+-- socket.create_connection now accepts an optional source_address parameter.
+-
+-- Issue #5511: now zipfile.ZipFile can be used as a context manager. Initial
+- patch by Brian Curtin.
+-
+-- Issue #7556: Make sure Distutils' msvc9compile reads and writes the MSVC XML
+- Manifest file in text mode so string patterns can be used in regular
+- expressions.
+-
+-- Issue #7552: Removed line feed in the base64 Authorization header in the
+- Distutils upload command to avoid an error when PyPI reads it. This occurs on
+- long passwords. Initial patch by JP St. Pierre.

+- Patch by Victor Stinner and Florent Xicluna.
+-
+-- Issue #7349: Make methods of file objects in the io module accept None as an
+- argument where file-like objects (ie StringIO and BytesIO) accept them to mean
+- the same as passing no argument.

+-- Issue #7333: The `posix` module gains an `initgroups()` function providing
+- access to the initgroups(3) C library call on Unix systems which implement it.
+- Patch by Jean-Paul Calderone.
+-
+-- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
+- ownership when the group is not forced, because the group may be different
+- from the user's group and inherit from its container when the test is run.
+-
+-- Issue #4486: When an exception has an explicit cause, do not print its
+- implicit context too. This affects the `traceback` module as well as built-in
+- exception printing.

+- Collins.
+-
+-- Issue #7403: logging: Fixed possible race condition in lock creation.

+-
+-- Issue #4969: The mimetypes module now reads the MIME database from the
+- registry under Windows. Patch by Gabriel Genellina.
+-
+-- Issue #6816: runpy now provides a run_path function that allows Python code to
+- execute file paths that refer to source or compiled Python files as well as
+- zipfiles, directories and other valid sys.path entries that contain a
+- __main__.py file. This allows applications that run other Python scripts to
+- support the same flexibility as the CPython command line itself.
+-
+-- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
+- connection with another process, rather than looping endlessly. The default
+- timeout is 20 seconds, which should be amply sufficient for local connections.
+-
+-- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and
+- unpickled. This fixes crashes under Windows when trying to run
+- test_multiprocessing in verbose mode.
+-
+-- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``
+- argument added to the TextTestRunner constructor allowing a different result
+- class to be used without having to subclass.
+-
+-- Issue #7588: ``unittest.TextTestResult.getDescription`` now includes the test
+- name in failure reports even if the test has a docstring.
+-
+-- Issue #3001: Add a C implementation of recursive locks which is used by
+- default when instantiating a `threading.RLock` object. This makes recursive
+- locks as fast as regular non-recursive locks (previously, they were slower by
+- 10x to 15x).
+-
+-- Issue #7282: Fix a memory leak when an RLock was used in a thread other than
+- those started through `threading.Thread` (for example, using
+- `_thread.start_new_thread()`).
+-
+-- Issue #7187: Importlib would not silence the IOError raised when trying to
+- write new bytecode when it was made read-only.
+-
+-- Issue #7264: Fix a possible deadlock when deallocating thread-local objects
+- which are part of a reference cycle.

+- objects on 64-bit systems. Patch by Michael Broghton.
+-
+-- Issue #6896: mailbox.Maildir now invalidates its internal cache each time a

+- on systems with slightly bogus mtime behaviour.
+-
+-- Issue #7246 & Issue #7208: getpass now properly flushes input before reading
+- from stdin so that existing input does not confuse it and lead to incorrect
+- entry or an IOError. It also properly flushes it afterwards to avoid the
+- terminal echoing the input afterwards on OSes such as Solaris.
+-
+-- Issue #7233: Fix a number of two-argument Decimal methods to make sure that
+- they accept an int or long as the second argument. Also fix buggy handling of
+- large arguments (those with coefficient longer than the current precision) in
+- shift and rotate.
+-
+-- Issue #4750: Store the basename of the original filename in the gzip FNAME

+- long(Decimal('nan')).
+-
+-- Issue #6850: Fix bug in Decimal._parse_format_specifier for formats with no
+- type specifier.
+-
+-- Issue #6239: ctypes.c_char_p return value must return bytes.
+-
+-- Issue #6838: Use a list to accumulate the value instead of repeatedly
+- concatenating strings in http.client's HTTPResponse._read_chunked providing a
+- significant speed increase when downloading large files servend with a
+- Transfer-Encoding of 'chunked'.
+-
+-- Trying to import a submodule from a module that is not a package, ImportError
+- should be raised, not AttributeError.
+-
+-- When the globals past to importlib.__import__() has __package__ set to None,
+- fall back to computing what __package__ should be instead of giving up.
+-
+-- Raise a TypeError when the name of a module to be imported for
+- importlib.__import__ is not a string (was raising an AttributeError before).
+-

+-
+-- Have importlib raise ImportError if None is found in sys.modules.
+-
+-- Issue #6054: Do not normalize stored pathnames in tarfile.

+-
+-- Issue #2715: Remove remnants of Carbon.File from binhex module.
+-
+-- Issue #6595: The Decimal constructor now allows arbitrary Unicode decimal

+-
+-- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
+- the documentation said it did even though the code in PyLoader relied on the
+- abstract method required by ResourceLoader.
+-

+-- Issue #4005: Fixed a crash of pydoc when there was a zip file present in
+- sys.path.
+-
+-- Issue #6218: io.StringIO and io.BytesIO instances are now picklable.
+-
+-- The os.get_exec_path() function to return the list of directories that will be
+- searched for an executable when launching a subprocess was added.
+-
+-- Issue #7481: When a threading.Thread failed to start it would leave the
+- instance stuck in initial state and present in threading.enumerate().
+-
+-- Issue #1068268: The subprocess module now handles EINTR in internal os.waitpid
+- and os.read system calls where appropriate.
+-
+-- Issue #6729: Added ctypes.c_ssize_t to represent ssize_t.
+-
+-- Issue #6247: The argparse module has been added to the standard library.
+-
+-- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is a socket
+- option available on FreeBSD 7.1 and newer.
+-
+-- Issue #9315: Fix for the trace module to record correct class name
+- for tracing methods.
+-
+-Extension Modules
+------------------
+-
+-- Issue #9959: Tweak formula used for computing math.log of an integer,
+- making it marginally more accurate for exact powers of 2.
+-
+-- Issue #9422: Fix memory leak when re-initializing a struct.Struct object.
+-
+-- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
+- compared to other unix systems. In particular, os.getgroups() does not reflect
+- any changes made using os.setgroups() but basicly always returns the same
+- information as the id command. os.getgroups() can now return more than 16
+- groups on MacOSX.
+-
+-- Issue #6095: Make directory argument to os.listdir optional.
+-
+-- Issue #9277: Fix bug in struct.pack for bools in standard mode (e.g.,
+- struct.pack('>?')): if conversion to bool raised an exception then that
+- exception wasn't properly propagated on machines where char is unsigned.
+-
+-- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x python when
+- they contain instances of old-style classes.
+-
+-- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to accompany
+- existing isinf and isnan functions.
+-
+-- Issue #1578269: Implement os.symlink for Windows 6.0+. Patch by Jason
+- R. Coombs.
+-
+-- In struct.pack, correctly propogate exceptions from computing the truth of an
+- object in the '?' format.
+-
+-- Issue #9000: datetime.timezone objects now have eval-friendly repr.
+-
+-- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
+- special methods.
+-
+-- Issue #9005: Prevent utctimetuple() from producing year 0 or year 10,000.
+- Prior to this change, timezone adjustment in utctimetuple() could produce
+- tm_year value of 0 or 10,000. Now an OverflowError is raised in these edge
+- cases.
+-
+-- Issue #6641: The ``datetime.strptime`` method now supports the ``%z``
+- directive. When the ``%z`` directive is present in the format string, an
+- aware ``datetime`` object is returned with ``tzinfo`` bound to a
+- ``datetime.timezone`` instance constructed from the parsed offset. If both
+- ``%z`` and ``%Z`` are present, the data in ``%Z`` field is used for timezone
+- name, but ``%Z`` data without ``%z`` is discarded.
+-
+-- Issue #5094: The ``datetime`` module now has a simple concrete class
+- implementing ``datetime.tzinfo`` interface. Instances of the new class,
+- ``datetime.timezone``, return fixed name and UTC offset from their
+- ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)`` method always
+- returns ``None``. A class attribute, ``utc`` contains an instance
+- representing the UTC timezone. Original patch by Rafe Kaplan.
+-
+-- Issue #8973: Add __all__ to struct module; this ensures that help(struct)
+- includes documentation for the struct.Struct class.
+-
+-- Issue #3129: Trailing digits in struct format string are no longer ignored.
+- For example, "1" or "ilib123" are now invalid formats and cause
+- ``struct.error`` to be raised. Patch by Caleb Deveraux.
+-
+-- Issue #7384: If the system readline library is linked against ncurses, the
+- curses module must be linked against ncurses as well. Otherwise it is not safe
+- to load both the readline and curses modules in an application.
+-
+-- Issue #2810: Fix cases where the Windows registry API returns ERROR_MORE_DATA,
+- requiring a re-try in order to get the complete result.
+-
+-- Issue #8692: Optimize math.factorial: replace the previous naive algorithm
+- with an improved 'binary-split' algorithm that uses fewer multiplications and
+- allows many of the multiplications to be performed using plain C integer
+- arithmetic instead of PyLong arithmetic. Also uses a lookup table for small
+- arguments.
+-
+-- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
+- overflow checks in the audioop module.
+-
+-- Issue #8644: The accuracy of td.total_seconds() has been improved (by
+- calculating with integer arithmetic instead of float arithmetic internally):
+- the result is now always correctly rounded, and is equivalent to ``td /
+- timedelta(seconds=1)``.
+-
+-- Issue #2706: Allow division of a timedelta by another timedelta: timedelta /
+- timedelta, timedelta % timedelta, timedelta // timedelta and divmod(timedelta,
+- timedelta) are all supported.
+-
+-- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
+-
+-- Issue #8300: When passing a non-integer argument to struct.pack with any
+- integer format code, struct.pack first attempts to convert the non-integer
+- using its __index__ method. If that method is non-existent or raises
+- TypeError it goes on to try the __int__ method, as described below.
+-
+-- Issue #8142: Update libffi to the 3.0.9 release.
+-
+-- Issue #6949: Allow the _dbm extension to be built with db 4.8.x.
+-
+-- Issue #6544: Fix a reference leak in the kqueue implementation's error
+- handling.
+-
+-- Stop providing crtassem.h symbols when compiling with Visual Studio 2010, as
+- msvcr100.dll is not a platform assembly anymore.
+-
+-- Issue #6508: Add posix.{getresuid,getresgid,setresuid,setresgid}.
+-
+-- Issue #7078: Set struct.__doc__ from _struct.__doc__.
+-
+-- Issue #3366: Add erf, erfc, expm1, gamma, lgamma functions to math module.
+-
+-- Issue #6877: It is now possible to link the readline extension to the libedit
+- readline emulation on OSX 10.5 or later.
+-
+-- Issue #6848: Fix curses module build failure on OS X 10.6.
+-
+-- Fix a segfault that could be triggered by expat with specially formed input.
+-
+-- Issue #6561: '\d' in a regex now matches only characters with Unicode category
+- 'Nd' (Number, Decimal Digit). Previously it also matched characters with
+- category 'No'.
+-
+-- Issue #4509: Array objects are no longer modified after an operation failing
+- due to the resize restriction in-place when the object has exported buffers.
+-
+-- Issue #2389: Array objects are now pickled in a portable manner.
+-
+-- Expat: Fix DoS via XML document with malformed UTF-8 sequences
+- (CVE_2009_3560).
+-
+-- Issue #7242: On Solaris 9 and earlier calling os.fork() from within a thread
+- could raise an incorrect RuntimeError about not holding the import lock. The
+- import lock is now reinitialized after fork.
+-
+-- Issue #7999: os.setreuid() and os.setregid() would refuse to accept a -1
+- parameter on some platforms such as OS X.
+-
+-- Build the ossaudio extension on GNU/kFreeBSD.
+-
+-- Issue #7347: winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in
+- the return value of QueryReflectionKey.
+-
+-- Issue #7567: PyCurses_setupterm: Don't call ``setupterm`` twice.
+-
+-Build
+------
+-
+-- Use OpenSSL 1.0.0a on Windows.
+-
+-- Issue #9280: Make sharedinstall depend on sharedmods.
+-
+-- Issue #9189: Make a user-specified CFLAGS, CPPFLAGS, or LDFLAGS setting
+- override the configure and makefile defaults, without deleting options the
+- user didn't intend to override. Developers should no longer need to specify
+- OPT or EXTRA_CFLAGS, although those variables are still present for
+- backward-compatibility.
+-
+-- Issue #8854: Fix finding Visual Studio 2008 on Windows x64.
+-
+-- Issue #1759169, #8864: Drop _XOPEN_SOURCE on Solaris, define it for
+- multiprocessing only.
+-
+-- Issue #8625: Turn off optimization in --with-pydebug builds with gcc.
+- (Optimization was unintentionally turned on in gcc --with-pydebug builds as a
+- result of the issue #1628484 fix, combined with autoconf's strange choice of
+- default CFLAGS produced by AC_PROG_CC for gcc.)
+-
+-- Issue #3646: It is now easily possible to install a Python framework into your
+- home directory on MacOSX, see Mac/README for more information.
+-
+-- Issue #3928: os.mknod() now available in Solaris, also.
+-
+-- Issue #3326: Build Python without -fno-strict-aliasing when the gcc does not
+- give false warnings.
+-
+-- Issue #1628484: The Makefile doesn't ignore the CFLAGS environment variable
+- anymore. It also forwards the LDFLAGS settings to the linker when building a
+- shared library.
+-
+-- Issue #6716: Quote -x arguments of compileall in MSI installer. Exclude 2to3
+- tests from compileall.
+-
+-- Issue #3920, #7903: Define _BSD_SOURCE on OpenBSD 4.4 through 4.9.
+-
+-- Issue #7632: When Py_USING_MEMORY_DEBUGGER is defined, disable the private
+- memory allocation scheme in dtoa.c and use PyMem_Malloc and PyMem_Free
+- instead. Also disable caching of powers of 5.
+-
+-- Issue #6491: Allow --with-dbmliborder to specify that no dbms will be built.
+-
+-- Issue #6943: Use pkg-config to find the libffi headers when the
+- --with-system-ffi flag is used.
+-
+-- Issue #7609: Add a --with-system-expat option that causes the system's expat
+- library to be used for the pyexpat module instead of the one included with
+- Python.
+-
+-- Issue #7589: Only build the nis module when the correct header files are
+- found.
+-
+-- Switch to OpenSSL 0.9.8l and sqlite 3.6.21 on Windows.
+-
+-- Issue #5792: Extend the short float repr support to x86 systems using

+-
+-- Issue #6802: Fix build issues on MacOSX 10.6.
+-
+-- Issue #6244: Allow detect_tkinter to look for Tcl/Tk 8.6.

+-
+-- Issue #8509: Fix quoting in help strings and code snippets in configure.in.
+-
+-- Issue #8510: Update to autoconf2.65.

+- with os.kill.
+-
+-- Issue #9255: Document that the 'test' package is meant for internal Python use

+- import lock was disabled.
+-
+-- Issue #8605: Skip test_gdb if Python is compiled with optimizations.
+-
+-- Issue #7449: Skip test_socketserver if threading support is disabled.
+-
+-- Issue #8672: Add a zlib test ensuring that an incomplete stream can be handled
+- by a decompressor object without errors (it returns incomplete uncompressed
+- data).
+-
+-- Issue #8533: regrtest uses backslashreplace error handler for stdout to avoid
+- UnicodeEncodeError (write non-ASCII character to stdout using ASCII encoding).
+-
+-- Issue #8576: Remove use of find_unused_port() in test_smtplib and
+- test_multiprocessing. Patch by Paul Moore.
+-
+-- Issue #7449: Fix many tests to support Python compiled without thread
+- support. Patches written by Jerry Seutter.

+- thread was previously started, most likely due to a platform bug.
+-
+-- Issue #8193: Fix test_zlib failure with zlib 1.2.4.
+-
+-- Issue #8248: Add some tests for the bool type. Patch by Gregory Nofi.

+- effectively raised.
+-
+-- The four path modules (genericpath, macpath, ntpath, posixpath) share a common
+- TestCase for some tests: test_genericpath.CommonTest.
+-
+-- Print platform information when running the whole test suite, or using the
+- --verbose flag.
+-
+-- Issue #767675: enable test_pep277 on POSIX platforms with Unicode-friendly
+- filesystem encoding.
+-
+-- Issue #6292: for the moment at least, the test suite runs cleanly if python is
+- run with the -OO flag. Tests requiring docstrings are skipped.
+-
+-- Issue #7712: test.support gained a new `temp_cwd` context manager which is now
+- also used by regrtest to run all the tests in a temporary directory. The
+- original CWD is saved in `support.SAVEDCWD`. Thanks to Florent Xicluna who
+- helped with the patch.
+-
+-- Issue #7924: Fix an intermittent 'XXX undetected error' failure in test_capi
+- (only seen so far on platforms where the curses module wasn't built), due to
+- an uncleared exception.
+-
+-- Issue #7728: test_timeout was changed to use support.bind_port instead of a
+- hard coded port.
+-
+-- Issue #7376: Instead of running a self-test (which was failing) when called
+- with no arguments, doctest.py now gives a usage message.
+-
+-- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.

+- instead of a hardcoded port number in test_rapid_restart.
+-
+-- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
+- in the Lib/test directory, which might be read-only for the user running the
+- tests.
+-
+-- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
+- of an option with no handler.
+-
+-- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
+- fails. Can be combined with -j.
+-
+-- Issue #6551: test_zipimport could import and then destroy some modules of the
+- encodings package, which would make other tests fail further down the road
+- because the internally cached encoders and decoders would point to empty
+- global variables.
+-
+-- Issue #7295: Do not use a hardcoded file name in test_tarfile.
+-
+-- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
+- primitives such as Lock, RLock, Condition, Event and Semaphore.
+-
+-- Issue #7248 (part 2): Use a unique temporary directory for importlib source
+- tests instead of tempfile.tempdir. This prevents the tests from sharing state
+- between concurrent executions on the same system.
+-
+-- Issue #7248: In importlib.test.source.util a try/finally block did not make
+- sure that some referenced objects actually were created in the block before
+- calling methods on the object.
+-
+-- Issue #7222: Make thread "reaping" more reliable so that reference
+- leak-chasing test runs give sensible results. The previous method of reaping
+- threads could return successfully while some Thread objects were still
+- referenced. This also introduces a new private function:
+- ``_thread._count()``.
+-
+-- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
+- runs the risk of causing the worker thread to fail.
+-
+-- Issue #7055: test___all__ now greedily detects all modules which have an
+- __all__ attribute, rather than using a hardcoded and incomplete list.
+-
+-- Issue #7058: Added save/restore for things like sys.argv and cwd to
+- runtest_inner in regrtest, with warnings if the called test modifies them, and
+- a new section in the summary report at the end.
+-
+-- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
+-
+-- Fixed tests in importlib.test.source.test_abc_loader that were masking the
+- proper exceptions that should be raised for missing or improper code object
+- bytecode.
+-
+-- Removed importlib's custom test discovery code and switched to
+- unittest.TestLoader.discover().
+-
+-Tools/Demos
+------------
+-
+-- Issue #5464, #8974: Implement plural forms in msgfmt.py.
+-
+-- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
+- added to the `Tools/` directory. They were previously living in the sandbox.

+-
+-- Issue #5994: the marshal module now has docstrings.

+- (1) inf and nan strings with trailing whitespace were incorrectly
+- rejected; (2) parsing of strings representing infinities and nans
+- was locale aware; and (3) the interpretation of fromhex('-nan')
+- didn't match that of float('-nan').
+-
+-Library
+--------
+-
+-- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
+-
+-- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
+-
+-- Issue #6121: pydoc now ignores leading and trailing spaces in the
+- argument to the 'help' function.
+-
+-- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
+- arguments for strings with a space in them.
+-
+-- collections.namedtuple() was not working with the following field
+- names: cls, self, tuple, itemgetter, and property.
+-
+-- In unittest, using a skipping decorator on a class is now equivalent to
+- skipping every test on the class. The ClassTestSuite class has been removed.
+-
+-- Issue #6050: Don't fail extracting a directory from a zipfile if
+- the directory already exists.
+-
+-- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
+- than an int, which makes some operations possible under 64-bit Linux (e.g.

+- file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
+- corrects a pydoc regression.

+- now be known as python3.
+-
+-- Lib/smtpd.py is no longer installed as a script.
+-
+-Extension Modules
+------------------
+-
+-- Issue #3061: Use wcsftime for time.strftime where available.
+-
+-- Issue #4873: Fix resource leaks in error cases of pwd and grp.
+-
+-- Issue #6093: Fix off-by-one error in locale.strxfrm.
+-
+-- The _functools and _locale modules are now built into the libpython shared
+- library instead of as extension modules.
+-
+-Build
+------
+-
+-- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
+- and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
+- Clinton Roy.
+-
+-Tests
+------
+-
+-- Issue #5442: Tests for importlib were not properly skipping case-sensitivity
+- tests on darwin even when the OS was installed on a case-sensitive
+- filesystem. Also fixed tests that should not be run when
+- sys.dont_write_bytecode is true.
+-
+-
+-What's New in Python 3.1 beta 1?
+-================================
+-
+-*Release date: 2009-05-06*
+-
+-Core and Builtins
+------------------
+-
+-- Issue #5914: Add new C API function PyOS_string_to_double, and
+- deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
+-
+-- Issue #3382: float.__format__, complex.__format__, and %-formatting
+- no longer map 'F' to 'f'. Because of issue #5859 (below), this only
+- affects nan -> NAN and inf -> INF.
+-
+-- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
+- in all operations, including splitdrive, split, etc. splitunc() now issues
+- a PendingDeprecation warning.
+-
+-- Issue #5920: For float.__format__, change the behavior with the
+- empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
+- to be like 'g' but with at least one decimal point and with a
+- default precision of 12. Previously, the behavior the same but with
+- a default precision of 6. This more closely matches str(), and
+- reduces surprises when adding alignment flags to the empty
+- presentation type. This also affects the new complex.__format__ in
+- the same way.
+-
+-- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
+-
+-- Issue #5890: in subclasses of 'property' the __doc__ attribute was
+- shadowed by classtype's, even if it was None. property now
+- inserts the __doc__ into the subclass instance __dict__.
+-
+-- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
+- sequences. Patch by Nick Barnes and Victor Stinner.
+-
+-- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
+-
+-- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
+- received a new method, detach(). detach() disconnects the underlying stream
+- from the buffer or text IO and returns it.
+-
+-- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
+- floats with absolute value over 1e50. Also remove length
+- restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
+- 12.34 no longer raise an exception.
+-
+-- Issue #1588: Add complex.__format__. For example,
+- format(complex(1, 2./3), '.5') now produces a sensible result.
+-
+-- Issue #5864: Fix empty format code formatting for floats so that it
+- never gives more than the requested number of significant digits.
+-
+-- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
+- new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
+-
+-- Issue #5835: Deprecate PyOS_ascii_formatd.
+-
+-- Issue #4971: Fix titlecase for characters that are their own
+- titlecase, but not their own uppercase.
+-
+-- Issue #5283: Setting __class__ in __del__ caused a segfault.
+-
+-- Issue #5816: complex(repr(z)) now recovers z exactly, even when
+- z involves nans, infs or negative zeros.
+-
+-- Issue #3166: Make int -> float conversions correctly rounded.
+-
+-- Issue #1869 (and many duplicates): make round(x, n) correctly
+- rounded for a float x, by using the decimal <-> binary conversions
+- from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
+- consistently agrees with format(x, '.2f').
+-
+-- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
+- some builtin types.
+-
+-- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
+-
+-- Issue #5515: str.format() type 'n' combined with commas and leading
+- zeros no longer gives odd results with ints and floats.
+-
+-- Implement PEP 378, Format Specifier for Thousands Separator, for
+- floats.
+-
+-- The str function switches to exponential notation at
+- 1e11, not 1e12. This avoids printing 13 significant digits in
+- situations where only 12 of them are correct. Example problem
+- value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
+- long time.)
+-
+-- Issue #1580: On most platforms, use a 'short' float repr: for a
+- finite float x, repr(x) now outputs a string based on the shortest
+- sequence of decimal digits that rounds to x. Previous behaviour was
+- to output 17 significant digits and then strip trailing zeros.
+- Another minor difference is that the new repr switches to
+- exponential notation at 1e16 instead of the previous 1e17; this
+- avoids misleading output in some cases.
+-
+- There's a new sys attribute sys.float_repr_style, which takes
+- the value 'short' to indicate that we're using short float repr,
+- and 'legacy' if the short float repr isn't available for one
+- reason or another.
+-
+- The float repr change involves incorporating David Gay's 'perfect
+- rounding' code into the Python core (it's in Python/dtoa.c). As a
+- secondary consequence, all string-to-float and float-to-string
+- conversions (including all float formatting operations) will be
+- correctly rounded on these platforms.
+-
+- See issue #1580 discussions for details of platforms for which
+- this change does not apply.
+-
+-- Issue #5759: float() didn't call __float__ on str subclasses.
+-
+-- The string.maketrans() function is deprecated; there is a new static method
+- maketrans() on the bytes and bytearray classes. This removes confusion about
+- the types string.maketrans() is supposed to work with, and mirrors the
+- methods available on the str class.
+-
+-- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
+- its clarity and its speed.
+-
+-- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add ``do { ... } while (0)``
+- to avoid compiler warnings.
+-
+-- Issue #3739: The unicode-internal encoder now reports the number of characters
+- consumed like any other encoder (instead of the number of bytes).
+-
+-Installation
+-------------
+-
+-- Issue #5756: Install idle and pydoc with a 3 suffix.
+-
+-Library
+--------
+-
+-- Issue #8203: Fix IDLE Credits dialog: view_file() uses its encoding argument.
+-
+-- Issue #5311: bdist_msi can now build packages that do not depend on a
+- specific Python version.
+-
+-- Issue #5150: IDLE's format menu now has an option to strip trailing
+- whitespace.
+-
+-- Issue #5940: distutils.command.build_clib.check_library_list was not doing
+- the right type checkings anymore.
+-
+-- Issue #4875: On win32, ctypes.util.find_library does no longer
+- return directories.
+-
+-- Issue #5142: Add the ability to skip modules while stepping to pdb.
+-
+-- Issue #1309567: Fix linecache behavior of stripping subdirectories when
+- looking for files given by a relative filename.
+-
+-- Issue #5923: Update the ``turtle`` module to version 1.1, add two new
+- turtle demos in Demo/turtle.
+-
+-- Issue #5692: In ``zipfile.Zipfile``, fix wrong path calculation when
+- extracting a file to the root directory.
+-
+-- Issue #5913: os.listdir() should fail for empty path on windows.
+-
+-- Issue #5084: unpickling now interns the attribute names of pickled objects,
+- saving memory and avoiding growth in size of subsequent pickles. Proposal
+- and original patch by Jake McGuire.
+-
+-- The json module now works exclusively with str and not bytes.
+-
+-- Issue #3959: The ipaddr module has been added to the standard library.
+- Contributed by Google.
+-
+-- Issue #3002: ``shutil.copyfile()`` and ``shutil.copytree()`` now raise an
+- error when a named pipe is encountered, rather than blocking infinitely.
+-
+-- Issue #5857: tokenize.tokenize() now returns named tuples.
+-
+-- Issue #4305: ctypes should now build again on mipsel-linux-gnu
+-
+-- Issue #1734234: Massively speedup ``unicodedata.normalize()`` when the
+- string is already in normalized form, by performing a quick check beforehand.
+- Original patch by Rauli Ruohonen.
+-
+-- Issue #5853: calling a function of the mimetypes module from several threads
+- at once could hit the recursion limit if the mimetypes database hadn't been
+- initialized before.
+-
+-- Issue #5854: Updated __all__ to include some missing names and remove some
+- names which should not be exported.
+-
+-- Issue #3102: All global symbols that the _ctypes extension defines
+- are now prefixed with 'Py' or '_ctypes'.
+-
+-- Issue #5041: ctypes does now allow pickling wide character.
+-
+-- Issue #5812: For the two-argument form of the Fraction constructor,
+- Fraction(m, n), m and n are permitted to be arbitrary Rational
+- instances.
+-
+-- Issue #5812: Fraction('1e6') is valid: more generally, any string
+- that's valid for float() is now valid for Fraction(), with the
+- exception of strings representing NaNs and infinities.
+-
+-- Issue #5734: BufferedRWPair was poorly tested and had several glaring
+- bugs. Patch by Brian Quinlan.
+-
+-- Issue #1161031: fix readwrite select flag handling: POLLPRI now
+- results in a handle_expt_event call, not handle_read_event, and POLLERR
+- and POLLNVAL now call handle_close, not handle_expt_event. Also,
+- dispatcher now has an 'ignore_log_types' attribute for suppressing
+- log messages, which is set to 'warning' by default.
+-
+-- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
+- new arguments introduced in 2.5.
+-
+-- Issue #5828 (Invalid behavior of unicode.lower): Fixed bogus logic in
+- makeunicodedata.py and regenerated the Unicode database (This fixes
+- u'\u1d79'.lower() == '\x00').
+-
+-Extension Modules
+------------------
+-
+-- Issue #5881: Remove old undocumented compatibility interfaces in hashlib and
+- pwd.
+-
+-- Issue #5463: In struct module, remove deprecated float coercion
+- for integer type codes: struct.pack('L', 0.3) should now raise
+- an error. The _PY_STRUCT_FLOAT_COERCE constant has been removed.
+- The version number has been bumped to 0.3.
+-
+-- Issue #5359: Readd the Berkeley DB detection code to allow _dbm be built
+- using Berkeley DB.
+-
+-Tests
+------
+-
+-- Issue #5354: New test support function import_fresh_module() makes
+- it easy to import both normal and optimised versions of modules.
+- test_heapq and test_warnings have been adjusted to use it, tests for
+- other modules with both C and Python implementations in the stdlib
+- can be adjusted to use it over time.
+-
+-- Issue #5837: Certain sequences of calls to set() and unset() for
+- support.EnvironmentVarGuard objects restored the environment variables
+- incorrectly on __exit__.
+-
+-C-API
+------
+-
+-- Issue #5630: A replacement PyCObject API, PyCapsule, has been added.
+-
+-
+-What's New in Python 3.1 alpha 2?
+-=================================
+-
+-*Release date: 2009-4-4*
+-
+-Core and Builtins
+------------------
+-
+-- Implement PEP 378, Format Specifier for Thousands Separator, for
+- integers.
+-
+-- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
+-
+-- Issue #5499: The 'c' code for argument parsing functions now only accepts a
+- byte, and the 'C' code only accepts a unicode character.
+-
+-- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
+- when hitting the recursion limit under certain circumstances.
+-
+-- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
+-
+-- Fix a segfault when running test_exceptions with coverage, caused by
+- insufficient checks in accessors of Exception.__context__.
+-
+-- Issue #5604: non-ASCII characters in module name passed to
+- imp.find_module() were converted to UTF-8 while the path is
+- converted to the default filesystem encoding, causing nonsense.
+-
+-- Issue #5126: str.isprintable() returned False for space characters.
+-
+-- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
+- the end sys.path, for compatibility with the system install of Python.
+-
+-- Issue #4688: Add a heuristic so that tuples and dicts containing only
+- untrackable objects are not tracked by the garbage collector. This can
+- reduce the size of collections and therefore the garbage collection overhead
+- on long-running programs, depending on their particular use of datatypes.
+-
+-- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
+- improve its performance. Long divisions and remainder operations
+- are now between 50% and 150% faster.
+-
+-- Issue #4258: Make it possible to use base 2**30 instead of base
+- 2**15 for the internal representation of integers, for performance
+- reasons. Base 2**30 is enabled by default on 64-bit machines. Add
+- --enable-big-digits option to configure, which overrides the
+- default. Add sys.int_info structseq to provide information about
+- the internal format.
+-
+-- Issue #4474: PyUnicode_FromWideChar now converts characters outside
+- the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
+- and sizeof(Py_UNICODE) == 2.
+-
+-- Issue #5237: Allow auto-numbered fields in str.format(). For
+- example: '{} {}'.format(1, 2) == '1 2'.
+-
+-- Issue #5392: when a very low recursion limit was set, the interpreter would
+- abort with a fatal error after the recursion limit was hit twice.
+-
+-- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
+- short file names.
+-
+-Library
+--------
+-
+-- Issue #2625: added missing items() call to the for loop in
+- mailbox.MH.get_message().
+-
+-- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
+- error substitutions from non-strict codec error callbacks in
+- incrementalencoder and StreamWriter.
+-
+-- Issue #5656: Fix the coverage reporting when running the test suite with
+- the -T argument.
+-
+-- Issue #5647: MutableSet.__iand__() no longer mutates self during iteration.
+-
+-- Issue #5624: Fix the _winreg module name still used in several modules.
+-
+-- Issue #5628: Fix io.TextIOWrapper.read() with a unreadable buffer.
+-
+-- Issue #5619: Multiprocessing children disobey the debug flag and causes
+- popups on windows buildbots. Patch applied to work around this issue.
+-
+-- Issue #5400: Added patch for multiprocessing on netbsd compilation/support
+-
+-- Issue #5387: Fixed mmap.move crash by integer overflow.
+-
+-- Issue #5261: Patch multiprocessing's semaphore.c to support context
+- manager use: "with multiprocessing.Lock()" works now.
+-
+-- Issue #5236: Change time.strptime() to only take strings. Didn't work with
+- bytes already but the failure was non-obvious.
+-
+-- Issue #5177: Multiprocessing's SocketListener class now uses
+- socket.SO_REUSEADDR on all connections so that the user no longer needs
+- to wait 120 seconds for the socket to expire.
+-
+-- Issue #5595: Fix UnboundedLocalError in ntpath.ismount().
+-
+-- Issue #1174606: Calling read() without arguments of an unbounded file
+- (typically /dev/zero under Unix) could crash the interpreter.
+-
+-- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
+- io.BufferedRandom have been deprecated for removal in Python 3.2.
+-
+-- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
+- forever on incomplete input. That caused tarfile.open() to hang when used
+- with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
+- partial bzip2 compressed data.
+-
+-- Issue #2110: Add support for thousands separator and 'n' type
+- specifier to Decimal.__format__
+-
+-- Fix Decimal.__format__ bug that swapped the meanings of the '<' and
+- '>' alignment characters.
+-
+-- The error detection code in FileIO.close() could fail to reflect the `errno`
+- value, and report it as -1 instead.
+-
+-- Issue #5016: FileIO.seekable() could return False if the file position
+- was negative when truncated to a C int. Patch by Victor Stinner.
+-
+-Extension Modules
+------------------
+-
+-- Issue #5391: mmap now deals exclusively with bytes.
+-
+-- Issue #5463: In struct module, remove deprecated overflow wrapping
+- when packing an integer: struct.pack('=L', -1) now raises
+- struct.error instead of returning b'\xff\xff\xff\xff'. The
+- _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
+- have been removed from the struct module.
+-
+-
+-What's New in Python 3.1 alpha 1
+-================================
+-
+-*Release date: 2009-03-07*
+-
+-Core and Builtins
+------------------
+-
+-- The io module has been reimplemented in C for speed.
+-
+-- Give dict views an informative __repr__.
+-
+-- Issue #5247: Improve error message when unknown format codes are
+- used when using str.format() with str, int, and float arguments.
+-
+-- Issue #5249: time.strftime returned malformed string when format string
+- contained non ascii character on windows.
+-
+-- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
+- source has already been decoded into str.
+-
+-- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
+- rotating the object pointer by 4 bits to the right.
+-
+-- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
+- it now forces its argument to double before testing for infinity.
+-
+-- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
+- returns a non-number type.
+-
+-- Issue #5182: Removed memoryview.__str__.
+-
+-- Issue #1717: Removed builtin cmp() function, dropped tp_compare
+- slot, the C API functions PyObject_Compare and PyUnicode_Compare and
+- the type definition cmpfunc. The tp_compare slot has been renamed
+- to tp_reserved, and is reserved for future usage.
+-
+-- Issue #1242657: the __len__() and __length_hint__() calls in several tools
+- were suppressing all exceptions. These include list() and bytearray().
+-
+-- Issue #4707: round(x, n) now returns an integer if x is an integer.
+- Previously it returned a float.
+-
+-- Issue #4753: By enabling a configure option named '--with-computed-gotos'
+- on compilers that support it (notably: gcc, SunPro, icc), the bytecode
+- evaluation loop is compiled with a new dispatch mechanism which gives
+- speedups of up to 20%, depending on the system, on various benchmarks.
+-
+-- Issue #4874: Most builtin decoders now reject unicode input.
+-
+-- Issue #4842: Don't allow trailing 'L' when constructing an integer
+- from a string.
+-
+-- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
+-
+-- Issue #4838: When a module is deallocated, free the memory backing the
+- optional module state data.
+-
+-- Issue #4910: Rename nb_long slot to nb_reserved, and change its
+- type to ``(void *)``.
+-
+-- Issue #4935: The overflow checking code in the expandtabs() method common
+- to str, bytes and bytearray could be optimized away by the compiler, letting
+- the interpreter segfault instead of raising an error.
+-
+-- Issue #3720: Fix a crash when an iterator modifies its class and removes its
+- __next__ method.
+-
+-- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
+- function no longer attempt to call the __long__ slot to convert an object
+- to an integer. Only the __int__ and __trunc__ slots are examined.
+-
+-- Issue #4893: Use NT threading on CE.
+-
+-- Issue #4915: Port sysmodule to Windows CE.
+-
+-- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
+- common cases are optimized thanks to a dedicated fast path and a moderate
+- amount of loop unrolling.
+-
+-- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
+- collecting the oldest generation) so that allocating lots of objects without
+- destroying them does not show quadratic performance. Based on a proposal by
+- Martin von Löwis at
+- http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
+-
+-- Issue #4604: Some objects of the I/O library could still be used after
+- having been closed (for instance, a read() call could return some
+- previously buffered data). Patch by Dmitry Vasiliev.
+-
+-- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
+- flag to work properly. Furthermore, when specifying -u, the text stdout
+- and stderr streams have line-by-line buffering enabled (the default being
+- to buffer arbitrary chunks of data).
+-
+-- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
+- instead of ints (reducing its size from 4 to 8 times thereby reducing
+- Python's overall memory).
+-
+-- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
+- an existing .py counterpart, override the co_filename attributes of all
+- code objects if the original filename is obsolete (which can happen if the
+- file has been renamed, moved, or if it is accessed through different paths).
+- Patch by Ziga Seilnacht and Jean-Paul Calderone.
+-
+-- Issue #4580: Fix slicing of memoryviews when the item size is greater than
+- one byte. Also fixes the meaning of len() so that it returns the number of
+- items, rather than the size in bytes.
+-
+-- Issue #4075: Use OutputDebugStringW in Py_FatalError.
+-
+-- Issue #4747: When the terminal does not use utf-8, executing a script with
+- non-ascii characters in its name could fail with a "SyntaxError: None" error.
+-
+-- Issue #4797: IOError.filename was not set when ``_fileio.FileIO`` failed
+- to open file with a bytes filename on Windows.
+-
+-- Issue #3680: Reference cycles created through a dict, set or deque iterator
+- did not get collected.
+-
+-- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
+- where the tp_hash and tp_dict slots are both NULL.
+-
+-- Issue #4759: None is now allowed as the first argument of
+- bytearray.translate(). It was always allowed for bytes.translate().
+-
+-- Added test case to ensure attempts to read from a file opened for writing
+- fail.
+-
+-- Issue #3106: Speedup some comparisons (str/str and int/int).
+-
+-- Issue #2183: Simplify and optimize bytecode for list, dict and set
+- comprehensions. Original patch for list comprehensions by Neal Norwitz.
+-
+-- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
+- print elapsed times, not only when some objects are uncollectable /
+- unreachable. Original patch by Neil Schemenauer.
+-
+-- Issue #3439: Add a bit_length method to int.
+-
+-- Issue #2173: When getting device encoding, check that return value of
+- nl_langinfo is not the empty string. This was causing silent build
+- failures on OS X.
+-
+-- Issue #4597: Fixed several opcodes that weren't always propagating
+- exceptions.
+-
+-- Issue #4589: Fixed exception handling when the __exit__ function of a
+- context manager returns a value that cannot be converted to a bool.
+-
+-- Issue #4445: Replace "sizeof(PyBytesObject)" with
+- "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
+- bytes instances. On a typical machine this saves 3 bytes of memory
+- (on average) per allocation of a bytes instance.
+-
+-- Issue #4533: File read operation was dreadfully slow due to a slowly
+- growing read buffer. Fixed by using the same growth rate algorithm as
+- Python 2.x.
+-
+-- Issue #4509: Various issues surrounding resize of bytearray objects to
+- which there are buffer exports (e.g. memoryview instances).
+-
+-- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
+- method on file objects with closefd=False. The file descriptor is still
+- kept open but the file object behaves like a closed file. The ``FileIO``
+- object also got a new readonly attribute ``closefd``.
+-
+-- Issue #4569: Interpreter crash when mutating a memoryview with an item size
+- larger than 1.
+-
+-- Issue #4748: Lambda generators no longer return a value.
+-
+-- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
+-
+-- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
+- PyUnicode_DecodeUTF8() once, remember the result and output it in a second
+- step. This avoids problems with counting UTF-8 bytes that ignores the effect
+- of using the replace error handler in PyUnicode_DecodeUTF8().
+-
+-Library
+--------
+-
+-- Issue #7071: byte-compilation in Distutils is now done with respect to
+- sys.dont_write_bytecode.
+-
+-- Issue #7066: archive_util.make_archive now restores the cwd if an error is
+- raised. Initial patch by Ezio Melotti.
+-
+-- Issue #6516: Added owner/group support when creating tar archives in
+- Distutils.
+-
+-- Issue #6954: Fixed crash when using DISTUTILS_DEBUG flag in Distutils.
+-
+-- Issue #6163: Fixed HP-UX runtime library dir options in
+- distutils.unixcompiler. Initial patch by Sridhar Ratnakumar and
+- Michael Haubenwallner.
+-
+-- Issue #6693: New functions in site.py to get user/global site packages paths.
+-
+-- Issue #6511: ZipFile now raises BadZipfile (instead of an IOError) when
+- opening an empty or very small file.
+-
+-- Issue #6545: Removed assert statements in distutils.Extension, so the
+- behavior is similar when used with -O.
+-
+-- unittest has been split up into a package. All old names should still work.
+-
+-- Issue #6466: now distutils.cygwinccompiler and distutils.emxccompiler
+- uses the same refactored function to get gcc/ld/dllwrap versions numbers.
+- It's `distutils.util.get_compiler_versions`. Added deprecation warnings

+-- Issue #4279: Fix build of parsermodule under Cygwin.

+- skip the tests if DISPLAY is defined but can't be used.
+-
+-- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
+- that should cause a test to be skipped are now done using import_module
+- from test support, which does the conversion.
