- using LTO, be sure to test things thoroughly before relying on it.
- It can provide a few % speed up over profile-opt alone.
-
-- Issue #26168: Fixed possible refleaks in failing Py_BuildValue() with the "N"
- format unit.

-
-- Issue #20440: Massive replacing unsafe attribute setting code with special
- macro Py_SETREF.

- * Extension module builds now revert to using system installed
- headers and libs (/usr and /System/Library) if the SDK used
- to build the interpreter is not installed or has moved.
- * Try to avoid building extension modules with deprecated
- and problematic Apple llvm-gcc compiler. If original compiler
- is not available, use clang instead by default.

-
-- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
- Distutils-based packages with C extension modules may fail because
- Apple has removed gcc-4.2, the version used to build python.org
- 64-bit/32-bit Pythons. If the user does not explicitly override
- the default C compiler by setting the CC environment variable,
- Distutils will now attempt to compile extension modules with clang
- if gcc-4.2 is required but not found. Also as a convenience, if
- the user does explicitly set CC, substitute its value as the default
- compiler in the Distutils LDSHARED configuration variable for OS X.
- (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
- SDK, neither of which are available in Xcode 4. This change does not
- attempt to override settings to support their use with Xcode 4.)

-- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
- check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
- interpreter process. This could cause failures in non-Distutils subprocesses

- environment after Distutils set it. Instead, have Distutils set the
- deployment target only in the environment of each build subprocess. It is
- still possible to globally override the default by setting
- MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
- greater or equal to the default value, the value with which the interpreter
- was built.

- updating the check interval, so if the user decreases the check interval,
- the ticker doesn't have to wind down to zero from the old starting point
- before the new interval takes effect. And if the user increases the
- interval, it makes sure the new limit takes effect right away rather have an
- early task switch before recognizing the new interval.
-
-- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the
- constructor has failed, e.g. because of an undeclared keyword argument. Patch
- written by Oleg Oshmyan.

-
-- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
- This prevents user-created self-referencing ordered dictionaries from

- the unordered versions inherited from dict. Those methods are now
- overridden to provide ordered views.
-
-- Issue #8688: MANIFEST files created by distutils now include a magic
- comment indicating they are generated. Manually maintained MANIFESTs
- without this marker will not be overwritten or removed.
-
-- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
- and a BadZipfile error is raised if it doesn't match (as used to be the
- case in Python 2.5 and earlier).
-
-- Issue #9550: a BufferedReader could issue an additional read when the
- original read request had been satisfied, which could block indefinitely
- when the underlying raw IO channel was e.g. a socket. Report and original
- patch by Jason V. Miller.
-
-- Issue #9551: Don't raise TypeError when setting the value to None for
- SafeConfigParser instances constructed with allow_no_value == True.
-
-- Issue #6915: Under Windows, os.listdir() didn't release the Global
- Interpreter Lock around all system calls. Original patch by Ryan Kelly.

- encoded word encoded in base64 is lacking padding.
-
-- Issue #9444: Argparse now uses the first element of prefix_chars as

-What's New in Python 2.7 Release Candidate 1?
-=============================================
-
-*Release date: 2010-06-05*
-
-Core and Builtins
------------------
-
-- 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 #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
- __hash__ in 3.x" warning. Also fix "XXX undetected error" that
- arises from the "Overriding __eq__ blocks inheritance ..." warning
- when turned into an exception: in this case the exception simply
- gets ignored.
-
-- 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 transivity 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 #5211: Implicit coercion for the complex type is now completely
- removed. (Coercion for arithmetic operations was already removed in 2.7
- alpha 4, but coercion for rich comparisons was accidentally left in.)
-
-- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
- and error handler, instead of writing to the C stderr file in utf-8
-
-- Issue #7902: When using explicit relative import syntax, don't try implicit
- relative import semantics.
-
-- Issue #7079: Fix a possible crash when closing a file object while using it
- from another thread. Patch by Daniel Stutzbach.
-
-- Issue #8868: Fix that ensures that python scripts have access to the
- Window Server again in a framework build on MacOSX 10.5 or earlier.
-
-C-API
------
-
-- Issue #5753: A new C API function, :cfunc:`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>`_.
-
-Library
--------

-
-*Release date: 2010-05-08*
-
-Core and Builtins
------------------
-
-- Run Clang 2.7's static analyzer for ``Objects/`` and ``Python/``.
-
-- Issue #1533: Fix inconsistency in range function argument processing: any
- non-float non-integer argument is now converted to an integer (if possible)
- using its __int__ method. Previously, only small arguments were treated this
- way; larger arguments (those whose __int__ was outside the range of a C long)
- would produce a TypeError.
-
-- 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 #7319: When -Q is used, do not silence DeprecationWarning.
-
-- 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 bytearray.
-
-- Issue #7072: ``isspace(0xa0)`` is true on Mac OS X.
-
-- Issue #8404: Fix set operations on dictionary views.
-
-- 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``.
-
-Library
--------
-
-- Issue #8681: Make the zlib module's error messages more informative when the
- zlib itself doesn't give any detailed explanation.
-
-- 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 #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 #7755: Use an unencumbered audio file for tests.

-- Issue #8313: ``traceback.format_exception_only()`` encodes unicode message to
- ASCII with backslashreplace error handler if ``str(value)`` failed.
-
-- 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 :mod:`io` objects should not swallow
- exceptions raised by the implicit flush(). Also ensure that calling close()
- several times is supported. Patch by Pascal Chambon.

-- Issue #8576: logging updated to remove usage of find_unused_port().
-
-- 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")``.
-
-- Issue #8577: ``distutils.sysconfig.get_python_inc()`` now makes a difference
- between the build dir and the source dir when looking for "python.h" or
- "Include".
-
-- Issue #8464: tarfile no longer creates files with execute permissions set when
- mode="w|" is used.
-
-- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions of
- the Linux kernel. Patch by Yaniv Aknin.
-
-- Issue #6312: Fix http HEAD request when the transfer encoding is chunked. It
- should correctly return an empty response now.
-
-- 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. Based on initial patch by Lennart Regebro.
-
-- Issue #8086: In :func:`ssl.DER_cert_to_PEM_cert()`, fix missing newline before
- the certificate footer. Patch by Kyle VanderBeek.
-
-- Issue #8546: Reject None given as the buffering argument to ``_pyio.open()``.

-
-- 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 #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 #7507: Quote "!" in pipes.quote(); it is special to some shells.
-
-- Issue #5238: Calling makefile() on an SSL object would prevent the underlying
- socket from being closed until all objects get truely destroyed.
-
-- Issue #7943: Fix circular reference created when instantiating an SSL socket.
- Initial patch by Péter Szabó.
-
-- 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 #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 #8437: Fix test_gdb failures, patch written by Dave Malcolm

- available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
-
-- Issue #2987: RFC 2732 support for urlparse (IPv6 addresses). Patch by Tony
- Locke and Hans Ulrich Niedermann.
-
-- 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.

-
-Build
------
-
-- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
- (Optimization was unintentionally turned on in gcc --with-pydebug builds in
- 2.7 beta1 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 #8509: Fix quoting in help strings and code snippets in configure.in.
-

-
-Core and Builtins
------------------
-
-- 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 #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 DeprecationWarning in
- Python 3.3 and it will be an error in Python 3.4.
-
-- Issue #8268: Old-style classes (not just instances) now support weak
- references.
-
-- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
- is set.
-
-- Issue #1583863: A unicode subclass can now override the __unicode__ method
-

- arguments to a function correct.
-
-- Issue #8164: Don't allow lambda functions to have a docstring.
-
-- 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.
-
-- Code objects now support weak references.
-
-Library
--------
-
-- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
-
-- 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`.
-
-- Issue #8310: Allow dis to examine new style classes.
-
-- 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')
-
-- collections.Counter() now supports a subtract() method.
-
-- The functools module now has a total_ordering() class decorator to simplify
- the specification of rich comparisons.
-
-- The functools module also adds cmp_to_key() as a tool to transition old-style
- comparison functions to new-style key-functions.
-
-- 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).
-
-- 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).
-
-- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
- function like a normal call.
-
-- 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.
-
-- Addition of ``WeakSet`` to the ``weakref`` module.
-
-- logging: Added LOG_FTP to SysLogHandler and updated documentation.
-
-- Issue #8205: Remove the "Modules" directory from sys.path when Python is

- deprecated.
-
-- Issue #7860: platform.uname now reports the correct 'machine' type when Python

- existing at the same time, causing a Unicode error when configuration code
- attempted to sort the existing loggers.
-
-- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
- when logging occurs.
-
-- 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 #8179: Fix macpath.realpath() on a non-existing path.
-
-- Issue #8024: Update the Unicode database to 5.2.
-
-- Issue #8104: socket.recv_into() and socket.recvfrom_into() now support writing
- into objects supporting the new buffer API, for example bytearrays or
- memoryviews.
-
-- 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 #7774: Set sys.executable to an empty string if ``argv[0]`` has been set
- to a non existent program name and Python is unable to retrieve the real
- program name.
-
-- Issue #8117: logging: Improved algorithm for computing initial rollover time
- for ``TimedRotatingFileHandler`` by using the modification time of an existing
- log file to compute the next rollover time. If the log file does not exist,
- the current time is used as the basis for the computation.
-
-- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The
- cElementTree module is updated too.
-
-- Issue #7880: Fix sysconfig when the python executable is a symbolic link.
-
-- Issue #7624: Fix ``isinstance(foo(), collections.Callable)`` for old-style
- classes.
-
-- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
- a base64 transfer-encoded payload *after* decoding it; it no longer does.
- This is a behavior change, so email's minor version number is now bumped, to
- version 4.0.2, for the 2.7 release.
-
-- Issue #8235: _socket: Add the constant ``SO_SETFIB``. SO_SETFIB is
- a socket option available on FreeBSD 7.1 and newer.
-
-- Issue #8038: unittest.TestCase.assertNotRegexpMatches
-
-- Addition of -b command line option to unittest for buffering stdout / stderr
- during test runs.
-
-- Issue #1220212: Added os.kill support for Windows, including support for
- sending CTRL+C and CTRL+BREAK events to console subprocesses.

-
-- Issue #3928: os.mknod() now available in Solaris, also.
-
-- Issue #8142: Update libffi to the 3.0.9 release.
-
-- 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 #1530559: When passing a non-integer argument to struct.pack with *any*
- integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
- argument's __int__ method to convert to an integer before packing. It also
- produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
- inconsistent: __int__ was used for some integer codes but not for others, and
- the set of integer codes for which it was used differed between native packing
- and standard packing.)
-
-- Issue #7347: _winreg: Add CreateKeyEx and DeleteKeyEx, as well as fix a bug in
- the return value of QueryReflectionKey.
-
-Tools/Demos

-
-- Make sure that the FreeBSD build of the included libffi uses the proper
- assembly file.
-
-C-API
------
-
-- 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 #7992: A replacement PyCObject API, PyCapsule, has been backported from
- Python 3.1. All existing Python CObjects in the main distribution have been
- converted to capsules. To address backwards-compatibility concerns,
- PyCObject_AsVoidPtr() was changed to understand capsules.
-
-Tests
------
-
-- Issue #3864: Skip three test_signal tests on freebsd6 because they fail if any
- thread was previously started, most likely due to a platform bug.
-

- 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.
-
-Tests
------
-
-- Issue #7849: The utility ``test.test_support.check_warnings()`` verifies if
- warnings are effectively raised. A new utility ``check_py3k_warnings()`` is
- available.
-
-- 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 ``test.test_support.SAVEDCWD``. Thanks to Florent
- Xicluna who helped with the patch.
-
-Build
------
-
-- Issue #3920, #7903: Define _BSD_SOURCE on OpenBSD 4.4 through 4.9.

-=================================
-
-*Release date: 2010-02-06*
-
-Core and Builtins
------------------
-
-- Issue #5677: Explicitly forbid write operations on read-only file objects,
- and read operations on write-only file objects. On Windows, the system C
- library would return a bogus result; on Solaris, it was possible to crash the
- interpreter. Patch by Stefan Krah.
-
-- Issue #7853: Normalize exceptions before they are passed to a context
- manager's ``__exit__()`` method.
-
-- Issue #7385: Fix a crash in ``PyMemoryView_FromObject()`` when
- ``PyObject_GetBuffer()`` fails. Patch by Florent Xicluna.

-- Issue #7819: Check ``sys.call_tracing()`` arguments types.
-
-- 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 #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.
-
-- Issue #7319, #7770: Silence ``DeprecationWarning`` by default when the -3
- option is not used.
-
-- Issue #2335: Backport set literals syntax from Python 3.x.
-

-
-- Issue #1967: Backport dictionary views from Python 3.x.
-
-Library
--------
-

- treated keyword arguments called 'self' or 'other' specially.
-
-- 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 #7869: logging: Improved diagnostic for format-time errors.
-
-- Issue #7868: logging: Added loggerClass attribute to Manager.
-
-- Issue #7851: logging: Clarification on logging configuration files.
-
-- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
- specified, rather than fall through to AF_PACKET (in the ``socket`` module).

- type is specified. Patch by Brian Curtin.
-
-- logging: Implemented PEP 391.
-
-- 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 an
- ``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 #7792: Registering non-classes to ABCs raised an obscure error.
-
-- Removed the deprecated functions ``verify()`` and ``vereq()`` from
- Lib/test/test_support.py.
-
-- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
- when the release file is empty.
-
-- Issue #7748: Since unicode values are supported for some metadata options in
- Distutils, the DistributionMetadata get_* methods will now return a utf-8
- encoded string for them. This ensures that the upload and register commands
- send the correct values to PyPI without any error.
-
-- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
- headers in multipart/signed MIME parts, which fixes one of the sources of

- by Brian Curtin.
-
-- Issue #5827: Make sure that normpath preserves unicode. Initial patch by
- Matt Giuca.
-
-- 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.
-

-What's New in Python 2.7 alpha 2?
-=================================
-
-*Release date: 2010-01-09*
-
-Core and Builtins
------------------

- 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 #5080: A number of functions and methods previously produced a
- DeprecationWarning when passed a float argument where an integer was expected.
- These functions and methods now raise TypeError instead. The majority of the
- effects of this change are in the extension modules, but some core functions
- and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
- and many unicode/str methods.
-
-- Issue #7604: Deleting an unset slotted attribute did not raise an
- AttributeError.
-
-- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)

-
-- Issue #7579: The msvcrt module now has docstrings for all its functions.
-
-- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
- used to drop the time part of the result.
-
-- 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 a long.
-
-- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
- same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
- in the subclass.
-
-- 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 #1680159: Unicode coercion during an 'in' operation no longer masks the
- underlying error when the coercion fails for the left hand operand.
-

-
-- Issue #7466: Segmentation fault when the garbage collector is called in the
- middle of populating a tuple. Patch by Florent Xicluna.
-
-Library
--------
-
-- 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 #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc
- when it has a fully qualified configuration prefix. Initial patch by
- Arfrever.
-
-- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
- renaming of `cPickle` to `pickle`. The warning was annoying since there's no
- alternative to cPickle if you care about performance. Patch by Florent
- Xicluna.
-
-- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by Victor
- Stinner.
-
-- Issue #7092: Fix the DeprecationWarnings emitted by the standard library when
- using the -3 flag. Patch by Florent Xicluna.
-
-- 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: ``httplib.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: ``zipfile.ZipFile`` can now be used as a context manager.
- Initial patch by Brian Curtin.
-
-- Distutils now correctly identifies the build architecture as "x86_64" when

-
-- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest file in text
- mode.
-
-- 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 #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 #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
- argument like other file objects.
-
-- Issue #7357: tarfile no longer suppresses fatal extraction errors by default.
-
-- Issue #7470: logging: Fix bug in Unicode encoding fallback.
-
-- Issue #5949: Fixed IMAP4_SSL hang when the IMAP server response is missing
- proper end-of-line termination.

- ``distutils.dist.DistributionMetadata``.
-
-- Issue #3745: Undo the 2.7a1 change to have hashlib to reject unicode and non
- buffer API supporting objects as input. That behavior is for 3.x only.
-
-C-API
------
-
-- Issue #7767: New function ``PyLong_AsLongLongAndOverflow()`` added, analogous
- to ``PyLong_AsLongAndOverflow()``.
-
-- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
- ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
- ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
- float arguments for integer format codes (other than 'L'): previously an
- attempt to pass a float resulted in a DeprecationWarning; now it gives a
- TypeError. For the 'L' format code (which previously had no warning) there is
- now a DeprecationWarning.
-
-- Issue #7033: Function ``PyErr_NewExceptionWithDoc()`` added.
-
-Build
------
-
-- 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.

- found.
-
-- Switch to OpenSSL 0.9.8l and sqlite 3.6.21 on Windows.

-
-
-What's New in Python 2.7 alpha 1
-================================
-
-*Release date: 2009-12-05*
-
-Core and Builtins
------------------
-
-- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
- when called with invalid values.
-
-- Issue #3382: 'F' formatting for float and complex now convert the result to
- upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
- to 'g' for large values.
-
-- Remove switch from "%f" formatting to "%g" formatting for floats larger than
- 1e50 in absolute value.
-
-- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
- 1e-100 used to raise OverflowError, but now gives the requested 120
- significant digits instead.
-
-- Add Py3k warnings for parameter names in parentheses.
-
-- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
-
-- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
- 10.6.
-
-- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
- decimal string that's guaranteed to round back to x under correct rounding
- (with round-half-to-even rounding mode). Previously it gave a string based on
- rounding x to 17 decimal digits. repr(x) for a complex number behaves
- similarly. On platforms where the correctly-rounded strtod and dtoa code is
- not supported (see below), repr is unchanged.
-
-- Issue #7117: On almost all platforms: float-to-string and string-to-float
- conversions within Python are now correctly rounded. Places these conversions
- occur include: str for floats and complex numbers; the float and complex
- constructors; old-style and new-style numeric formatting; serialization and
- deserialization of floats and complex numbers using marshal, pickle and json;
- parsing of float and imaginary literals in Python code; Decimal-to-float
- conversion.
-
- The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
- providing correctly-rounded strtod and dtoa C functions. This code is
- supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
- the C compiler. There may be a small number of platforms on which correct
- operation of this code cannot be guaranteed, so the code is not used: notably,
- this applies to platforms where the C double format is not IEEE 754 binary64,
- and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
- and Python's configure script is unable to determine how to change the FPU
- precision. On these platforms conversions use the platform strtod and dtoa,
- as before.
-
-- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
- uses the correctly-rounded string <-> float conversions described above (when
- available), and so produces correctly rounded results that will display nicely
- under the float repr. There are two related small changes: (1) round now
- accepts any class with an ``__index__()`` method for its second argument (but
- no longer accepts floats for the second argument), and (2) an excessively
- large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
- raises an exception.
-
-- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
-
-- Fix several issues with ``compile()``. The input can now contain Windows and
- Mac newlines and is no longer required to end in a newline.
-
-- Remove length limitation when constructing a complex number from a unicode
- string.
-
-- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised
- during the formation of an output tuple.
-
-- Issue #1087418: Boost performance of bitwise operations for longs.
-
-- 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 #7168: Document ``PyFloat_AsString()`` and ``PyFloat_AsReprString()``,
- and note that they are unsafe and deprecated.
-
-- Issue #7120: logging: Remove import of multiprocessing which is causing crash
- in GAE.
-
-- Issue #7140: The ``__dict__`` of a module should not be cleared unless the
- module is the only object holding a reference to it.
-
-- 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 #7084: Fix a (very unlikely) crash when printing a list from one thread,
- and mutating it from another one. Patch by Scott Dial.
-
-- 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 #7050: Fix a SystemError when trying to use unpacking and augmented
- assignment.
-
-- Issue #5329: Fix ``os.popen*`` regression from 2.5 with commands as a sequence
- running through the shell. Patch by Jean-Paul Calderone and Jani Hakala.
-
-- 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 #6300: unicode.encode, unicode.decode, str.decode, and str.encode now
- take keyword arguments.
-
-- Issue #6922: Fix an infinite loop when trying to decode an invalid UTF-32
- stream with a non-raising error handler like "replace" or "ignore".
-
-- Issue #6713: Improve performance of base 10 int -> string and long -> string
- conversions.
-
-- Issue #1590864: Fix potential deadlock when mixing threads and fork().
-
-- Issue #6844: Do not emit DeprecationWarnings when accessing a "message"
- attribute on exceptions that was set explicitly.
-
-- Issue #6846: Fix bug where bytearray.pop() returns negative integers.
-
-- ``classmethod()`` no longer checks if its argument is callable.
-
-- Issue #6750: A text file opened with ``io.open()`` could duplicate its output
- when writing from multiple threads at the same time.
-
-- Issue #6704: Improve the col_offset in AST for "for" statements with a target
- of tuple unpacking.
-
-- 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 #1616979: Added the cp720 (Arabic DOS) encoding.
-
-- Issue #6070: On posix platforms import no longer copies the execute bit from
- the .py file to the .pyc file if it is set. Patch by Marco N.
-
-- Issue #4618: When unicode arguments are passed to ``print()``, the default
- separator and end should be unicode also.
-
-- Issue #6119: Fixed an incorrect Py3k warning about order comparisons of
- built-in functions and methods.
-
-- 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 #4856: Remove checks for win NT.
-
-- Issue #2016: Fixed a crash in a corner case where the dictionary of keyword
- arguments could be modified during the function call setup.
-
-- Removed the ipaddr module.
-
-- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
- because it wasn't recognized as a sequence).
-
-- Issue #6289: Encoding errors from ``compile()`` were being masked.
-
-- When no module is given in a relative import, the module field of the
- ImportFrom AST node is now None instead of an empty string.
-
-- Assignment to None using import statements now raises a SyntaxError.
-
-- Issue #4547: When debugging a very large function, it was not always possible
- to update the lineno attribute of the current frame.
-
-- Issue #5330: C functions called with keyword arguments were not reported by
- the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
-
-- 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 #6101: A new opcode, SETUP_WITH, has been added to speed up the with
- statement and correctly lookup the __enter__ and __exit__ special methods.
-
-- 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.
-
-- ``__instancecheck__()`` and ``__subclasscheck__()`` are now completely ignored
- on classic classes and instances.
-
-- 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').
-
-- 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.
-
-- 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 #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 #4971: Fix titlecase for characters that are their own titlecase, but
- not their own uppercase.
-
-- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
- _PyOS_double_to_string or PyOS_double_to_string.
-
-- 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.
-
-- Implement PEP 378, Format Specifier for Thousands Separator, for floats, ints,
- and longs.
-
-- Issue #5515: 'n' formatting for ints, longs, and floats handles leading zero
- formatting poorly.

- 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

-- 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 #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
-
-- 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

-
-- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
- interpreter to abort ("Fatal Python error: Could not reset the stack!")
- instead of throwing a MemoryError.

- __future__ import didn't work.
-
-- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
- because it is a reserved word in 3.x.
-
-- On windows, ``os.chdir()`` given unicode was not working if
- GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
- this code path is really executed because I cannot move to such directory on
- win2k)
-
-- Issue #4069: When ``set.remove(element)`` is used with a set element, the
- element is temporarily replaced with an equivalent frozenset. But the
- eventual KeyError would always report the empty ``frozenset()`` as the missing
- key. Now it correctly refers to the initial element.

-
-- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
- returned them on 64bit platforms.
-
-- Issue #5108: Handle %s like %S and %R 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().
-
-- Issue #3739: The unicode-internal encoder now reports the number of characters
- consumed like any other encoder (instead of the number of bytes).
-
-- 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.

-Extension Modules
------------------
-
-- 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 #6823: Allow time.strftime() to accept a tuple with a isdst field
- outside of the range of [-1, 1] by normalizing the value to within that range.
-
-- Issue #6877: Make it possible to link the readline extension to libedit on
- OSX.
-
-- Issue #6944: Fix a SystemError when socket.getnameinfo() was called with
- something other than a tuple as first argument.
-
-- Issue #6865: Fix reference counting issue in the initialization of the pwd
- module.
-
-- Issue #6848: Fix curses module build failure on OS X 10.6.
-
-- Fix a segfault in expat when given a specially crafted input lead to the
- tokenizer not stopping. CVE-2009-3720.
-
-- 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 #1523: Remove deprecated overflow wrapping for struct.pack with an
- integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
- consistently raises struct.error.
-
-- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the
- integer formats ('bBhHiIlLqQ'). In the following, '*' represents any of '=',
- '<', '>'.
-
- - Packing a float now always gives a Deprecation Warning. Previously it
- only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
-
- - If x is not an int, long or float, then packing x will always result in
- struct.error. Previously an x with an __int__ method could be packed by
- 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
- __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
- neither __int__ nor __long__, TypeError used to be raised (with a
- confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
- struct.error in other cases.
-
- Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
- argument with an __int__ method can be packed, but use of this feature
- triggers a DeprecationWarning.
-
-- Issue #4873: Fix resource leaks in error cases of pwd and grp.
-
-- Issue #4751: For hashlib algorithms provided by OpenSSL, the Python GIL is now
- released during computation on data lengths >= 2048 bytes.
-
-- Issue #3745: Fix hashlib to always reject unicode and non buffer-api
- supporting objects as input no matter how it was compiled (built in
- implementations or external openssl library). NOTE: Undone in 2.7a2.
-
-- Issue #4397: Fix occasional test_socket failure on OS X.
-
-- Issue #4279: Fix build of parsermodule under Cygwin.
-
-- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
-
-- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.
-
-- Issue #1040026: Fix os.times result on systems where HZ is incorrect.

-- Issue #5228: Make functools.partial objects can now be pickled.
-
-Tests
------
-
-- 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 #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 #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.
-
-- Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves
- off the trailing 0 in the version number.
-
-- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
- Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
- the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
- the tests if DISPLAY is defined but can't be used.
-
-- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
- regression tests in parallel, shortening the total runtime.
-
-- 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.
-
-- Fix test_warnings to no longer reset the warnings filter.
-
-- Fix test_logging to no longer reset the warnings filter.
-
-- Issue #5635: Fix running test_sys with tracing enabled.
-
-- 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.
-
-- Issue #5083: New 'gui' resource for regrtest.
-
-- Issue #5837: Certain sequences of calls to set() and unset() for
- support.EnvironmentVarGuard objects restored the environment variables
- incorrectly on __exit__.
-
-- Issue #2389: Array objects are now pickled in a portable manner.
-
-Misc
-----
-
-- Issue #5611: Auto-detect whether a C file uses tabs or spaces in Vim.

-
-- Issue #3547: Fixed ctypes structures bitfields of varying integer
- sizes.
-
-- Issue #3879: A regression in urllib.getproxies_environment was fixed.

-What's New in Python 2.6 release candidate 2?
-=============================================
-
-*Release date: 17-Sep-2008*
-

------------------
-
-- Security Issue #2: imageop did not validate arguments correctly and could
- segfault as a result.
-
-- Issue #3886: Possible integer overflows in the _hashopenssl module were
- closed.
-
-Tools/Demos
------------
-
-- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise

- C runtime in the Windows installer.
-
-
-What's New in Python 2.6 release candidate 1?
-=============================================
-
-*Release date: 12-Sep-2008*
-
-Core and Builtins
------------------
-
-- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
-
-- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
- PyString_FromFormat or PyErr_Format to display size_t values. The macro
- PY_FORMAT_SIZE_T is designed to select the correct format for the OS
- ``printf`` function, whereas PyString_FromFormat has an independent
- implementation and uses "%zd" on all platforms for size_t values.
- This makes a difference on win64, where ``printf`` needs "%Id" to display
- 64bit values.
-
-- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
- error.
-
-- Issue #3777: long() applied to a float object now always return a long
- object; previously an int would be returned for small values. the __long__
- method is allowed to return either an int or a long, but the behaviour of
- float objects should not change to respect backward compatibility.
-
-- Issue #3751: str.rpartition would perform a left-partition when called with
- a unicode argument.
-
-- Issue #3683: Fix compilation when --without-threads is given.
-
-- Issue #3668: Fix a memory leak with the "s*" argument parser in
- PyArg_ParseTuple and friends, which occurred when the argument for "s*"
- was correctly parsed but parsing of subsequent arguments failed.
-
-- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
- match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
- mechanism. In the process, fix a bug where isinstance() and issubclass(),
- when given a tuple of classes as second argument, were looking up
- __instancecheck__ / __subclasscheck__ on the tuple rather than on each
- type object.
-
-- Fix crashes on memory allocation failure found with failmalloc.
-
-- Fix memory leaks found with valgrind and update suppressions file.
-
-- Fix compiler warnings in opt mode which would lead to invalid memory reads.
-
-- Fix problem using wrong name in decimal module reported by pychecker.
-
-- Silenced another compiler warning about a used but not defined
- function 'stringlib_contains_obj'.
-
-- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
- ``__delslice__``.
-
-- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
- library targets in the Makefile.
-
-- Issue #1204: The configure script now tests for additional libraries
- that may be required when linking against readline. This fixes issues
- with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
-
-C-API
------
-
-- Aliased PyObject_Bytes to PyObject_Str.
-
-Library
--------
-
-- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
- stack usage in the case of deeply nested objects.
-
-- Issue #3629: Fix sre "bytecode" validator for an end case.
-
-- Issue #3811: The Unicode database was updated to 5.1.
-

-
-- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
-
-- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
- return a list or None rather than a custom object.
-
-- Issue #1638033: Cookie.Morsel gained the httponly attribute.
-
-- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

- non-ascii characters and Unicode in setup.py meta-data.
-
-- Issue #3726: Allow spaces in separators in logging configuration files.
-
-- Issue #3719: platform.architecture() fails if there are spaces in the
- path to the Python binary.
-
-- Issue #3602: Moved test.test_support.catch_warning() to
- warnings.catch_warnings() along with some API cleanup. Expanding the tests
- for catch_warnings() also led to an improvement in the raising of a
- DeprecationWarning related to warnings.warn_explicit().
-
-- The deprecation warnings for the old camelCase threading API were removed.
-
-- logging: fixed lack of use of encoding attribute specified on a stream.
-
-- Silenced a trivial compiler warning in the sqlite module.
-
-- Fixed two format strings in the _collections module.
-

- directory.
-
-- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
- non-integer floating point number.
-
-- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing
- SEM_VALUE_MAX.
-
-Extension Modules
------------------
-
-- Issue #4301: Patch the logging module to add processName support, remove
- _check_logger_class from multiprocessing.
-
-- Issue #2975: When compiling several extension modules with Visual Studio 2008

-
-
-What's New in Python 2.6 beta 3?
-================================
-
-*Release date: 20-Aug-2008*
-
-Core and Builtins
------------------
-
-- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
- Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
- extensions do not automatically benefit from the class attribute
- cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
- to their tp_flags field if they care. This is a backwards
- compatibility feature; in 3.0, all types will use the cache by
- default.
-
-- Keyword arguments can now follow starred arguments. (``f(a, *args,
- keyword=23)`` is now valid syntax.)
-
-- ctypes function pointers that are COM methods have a boolean True
- value again.
-
-- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
- by denying s# to parse objects that have a releasebuffer procedure,
- and introducing s*.
-
-- Issue #3537: Fix an assertion failure when an empty but presized dict
- object was stored in the freelist.
-
-- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
- ValueError consistently across platforms.
-
-- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
- (64bit Unix, for example), unichr() would truncate its argument and return
- u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
-
-- Apply security patches from Apple.
-
-- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
- PyErr_ExceptionMatches returns 0 when an exception occurs there.
-
-- Issue #1819: function calls with several named parameters are now on
- average 35% faster (as measured by pybench).
-
-- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
- the python debugger steps into a class statement: the free variables (local
- variables defined in an outer scope) would be deleted from the outer scope.
-
-- Issue #2620: Overflow checking when allocating or reallocating memory
- was not always being done properly in some python types and extension
- modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
- all been updated to perform better checks and places in the code that
- would previously leak memory on the error path when such an allocation
- failed have been fixed.
-
-Library
--------
-
-- Issue #3612: Added some missing basic types in ctypes.wintypes.
-
-- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
- symtable.Symbol have been deprecated for removal in 3.0 and the next release.
-
-- Issue #2234: distutils failed for some versions of the cygwin compiler. The
- version reported by these tools does not necessarily follow the python
- version numbering scheme, so the module is less strict when parsing it.
-
-- Issue #2235: Added Py3k warnings for types which will become unhashable
- under the stricter __hash__ inheritance rules in 3.0. Several types
- which did not meet the rules for hash invariants and were already
- unhashable in 3.0 have now been explicitly flagged as unhashable in
- 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
- xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
-
-- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
- imported into the module but exposed as part of the module's API.
-
-- Remove an unneeded import of abc.ABCMeta from 'inspect'.
-
-- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
-
-- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
-
-- Issue #3575: Incremental decoder's decode function now takes bytearray
- by using 's*' instead of 't#'.
-
-- Issue #2222: Fixed reference leak when occurred os.rename()
- fails unicode conversion on 2nd parameter. (windows only)
-
-- Issue #2464: urllib2 now supports a malformation in the URL received
- in a redirect.
-
-- Silence the DeprecationWarning raised when importing mimetools in
- BaseHTTPServer, cgi (and rfc822), httplib.
-
-- Issue #2776: fixed small issue when handling a URL with double slash
- after a 302 response in the case of not going through a proxy.
-
-- Issue #2676: in the email package, content-type parsing was hanging on
- pathological input because of quadratic or exponential behaviour of a
- regular expression.
-
-- Issue #3476: binary buffered reading through the new "io" library is now
- thread-safe.
-
-- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
- since mimetools itself is deprecated. Because modules are cached, all
- subsequent imports of rfc822 will not raise a visible DeprecationWarning.
-
-- Issue #3134: shutil referenced undefined WindowsError symbol.
-
-- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
- menu entries were not deleted.
-
-- Copied the implementation of reduce() to _functools.reduce() to have a
- version that did not raise a DeprecationWarning under -3.
-
-- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
- a MemoryError rather than silently stop the iteration.
-
-- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
- to _sre.compile() will now be rejected. This should not affect anybody
- since the re.compile() function never generates invalid re-bytecode.
-
-- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
- upon first access it can be automatically initialized from the csv file if
- it wasn't initialized during instantiation.
-
-- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
- the reload() built-in has been removed.
-
-- Changed code in the following modules/packages to remove warnings raised
- while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
- ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
- filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
- pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
- subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
- threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
-
-- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
- raised an AttributeError.
-
-- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
- asking for a specific length. This problem only affected files opened
- using the new "io" module, not the built-in open() function.
-
-- Issue #3449: Update decimal module to use most recent specification
- (v. 1.68) and tests (v. 2.58) from IBM.
-
-- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
-

- configuration files.
-
-- Deprecate the sunaudio module for removal in Python 3.0.
-
-- Issue #3394: zipfile.writestr sets external attributes when passed a
- file name rather than a ZipInfo instance, so files are extracted with
- mode 0600 rather than 000 under Unix.
-
-- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
- argument in python 2.5, this broke code that subclassed Popen to include its
- own poll method. Fixed my moving _deadstate to an _internal_poll method.
-
-Build
------
-
-- Generate the PatternGrammar pickle during "make install".
-
-Documentation
--------------
-

-- Issue #643841: The language reference now provides more detailed
- coverage of the lookup process for special methods. The disclaimers
- regarding lack of coverage of new-style classes have also been
- removed, since the coverage is now fairly reasonable.
-
-
-What's New in Python 2.6 beta 2?
-================================
-
-*Release date: 17-Jul-2008*
-
-Core and Builtins
------------------
-
-- Issue #3156: Fix inconsistent behavior of the bytearray type: all
- its methods now allow for items objects that can be converted to
- an integer using operator.index().
-
-- Issue #3360: Fix incorrect parsing of '020000000000.0', which
- produced a ValueError instead of giving the correct float.
-
-- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
- for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
-
-- Issue #3008: the float type has a new instance method 'float.hex'
- and a new class method 'float.fromhex' to convert floating-point
- numbers to and from hexadecimal strings, respectively.
-
-- Issue #2235: __hash__ is once again inherited by default. To allow
- collections.Hashable to remain meaningful in the presence of the
- default hash implementation (object.__hash__), it is now possible
- to explicit block inheritance of hash by setting __hash__=None at
- the Python level, or tp_hash=PyObject_HashNotImplemented at the C
- level.
-
-- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
- the parent module cannot be found while performing an absolute import.
- This means that an incorrectly defined __package__ attribute will
- now only prevent relative imports in that module rather than causing
- all imports from that module to fail.
-
-- Issue #2517: Allow unicode messages in Exceptions again by correctly
- bypassing the instance dictionary when looking up __unicode__ on
- new-style classes.
-
-- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
- set to a custom object whose write() method happens to install
- another file in sys.stdout.
-
-- Issue #3088: Corrected a race condition in classes derived from
- threading.local: the first member set by a thread could be saved in
- another thread's dictionary.
-
-- Issue #3004: Minor change to slice.indices(): the start and stop
- arguments are now treated identically, making the behaviour easier
- to describe and understand. For example, slice(None, -10,
- 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
- slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
- 10, -1).
-
-- Issue #3219: Calling a function with repeated keyword arguments,
- f(a=2, a=23), would not cause a syntax error. This was a regression
- from 2.4 caused by the switch to the new compiler.
-
-- Issue #2862: Make int and float freelist management consistent with
- other freelists. Changes their CompactFreeList apis into
- ClearFreeList apis and calls them via gc.collect().
-
-Library
--------
-
-- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
- api functions without holding the GIL, which could lead to a fatal
- error when they failed.
-
-- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
-
-- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

- ForkingPickler.register() to resolve conflict with ctypes.
-
-- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
-
-- Issue #3313: Fixed a crash when a failed dlopen() call does not set
- a valid dlerror() message.
-
-- Issue #3258: Fixed a crash when a ctypes POINTER type to an
- incomplete structure was created.
-
-- Issue #3339: dummy_thread.acquire() should not return None.
-
-- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
-
-- Issue #3301: Bisect module behaved badly when lo was negative.
-
-- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
- both unnecessary (HTTP allows text content to be sent in several forms) and
- wrong because the actual transmitted size could differ from the
- content-length. The problem had been corrected in the 2.4 branch, but never
- merged into trunk.
-
-- Issue #2663: add filtering capability to shutil.copytree().
-
-- Issue #1622: Correct interpretation of various ZIP header fields.
-
-- Issue #1526: Allow more than 64k files to be added to Zip64 file.
-
-- Issue #1746: Correct handling of zipfile archive comments (previously
- archives with comments over 4k were flagged as invalid). Allow writing
- Zip files with archives by setting the 'comment' attribute of a ZipFile.
-
-- Issue #449227: The rlcompleter module now adds "(" to callable objects
- when completed.
-
-- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
- handling is now the same as that of other special attributes like __name__).
-
-- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
- removal in Python 3.0 in favor of urllib2.urlopen().
-
-- Issue #2113: Fix error in subprocess.Popen if the select system call is
- interrupted by a signal.
-
-- Issue #3309: Fix bz2.BZFile iterator to release its internal lock
- properly when raising an exception due to the bz2file being closed.
- Prevents a deadlock.
-
-- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
- redundant ":443" port number designation when the connection is using the
- default https port (443).
-
-- Issue #874900: after an os.fork() call the threading module state is cleaned
- up in the child process to prevent deadlock and report proper thread counts
- if the new process uses the threading module.
-
-Tests
------
-
-- test.test_support.catch_warning now keeps track of all warnings it sees
- and is now better documented. Explicit unit tests for this context manager
- have been added to test_warnings.
-
-Build
------
-
-- Issue #3215: Build sqlite3 as sqlite3.dll, not sqlite3.pyd.
-
-Documentation
--------------
-
-- Document that robotparser has been renamed to urllib.robotparser in
- Python 3.0.

-
-- Document that urllib2 is split across multiple modules and renamed in
- Python 3.0.

-What's New in Python 2.6 beta 1?
-================================
-
-*Release date: 18-June-2008*
-
-Core and Builtins
------------------
-
-- Issue #3211: warnings.warn_explicit() did not guard against its 'registry'
- argument being anything other than a dict or None. Also fixed a bug in error
- handling when 'message' and 'category' were both set to None, triggering a
- bus error.
-
-- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
- holds the last (strong) reference to its referent.
-
-- Add future_builtins.ascii().
-
-- Several set methods now accept multiple arguments: update(), union(),
- intersection(), intersection_update(), difference(), and difference_update().
-
-- Issue #2898: Added sys.getsizeof() to retrieve size of objects in bytes.
-

-
-- Issue #2863: generators now have a ``gen.__name__`` attribute that
- equals ``gen.gi_code.co_name``, like ``func.__name___`` that equals
- ``func.func_code.co_name``. The repr() of a generator now also
- contains this name.
-
-- Issue #2831: enumerate() now has a ``start`` argument.
-
-- Issue #2801: fix bug in the float.is_integer method where a
- ValueError was sometimes incorrectly raised.

- attribute.
-
-- Issue #2196: hasattr() now lets exceptions which do not inherit
- Exception (KeyboardInterrupt, and SystemExit) propagate instead of
- ignoring them.
-
-- Added checks for integer overflows, contributed by Google. Some are
- only available if asserts are left in the code, in cases where they
- can't be triggered from Python code.
-
-Extension Modules
------------------

-
-- Issue #3116: marshal.dumps() had quadratic behavior for strings > 32Mb.
-
-- Issue #2138: Add factorial() to the math module.
-

- PyString names.
-
-
-What's New in Python 2.6 alpha 3?
-=================================
-
-*Release date: 08-May-2008*
-
-Core and builtins
------------------
-
-- Issue #2719: backported the ``next()`` builtin from Python 3.
-
-- Issue #2681: The octal literal ``0o8`` was incorrecly acctepted. Now
- it properly raises a SyntaxError.
-
-- Issue #2617: Reserved -J and -X arguments for Jython, IronPython and
- other implementations of Python.
-
-- Implemented PEP 370: Per user site-packages directory.
-
-Extension Modules
------------------
-
-- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
- two handlers that derive the same default base class.
-
-- Added kill, terminate and send_signal(sig) to subprocess.Popen.
-
-- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
- the cmath module.
-
-- Four new methods were added to the math and cmath modules: acosh,
- asinh, atanh and log1p.
-
-- zlib.decompressobj().flush(value) no longer crashes the interpreter
- when passed a value less than or equal to zero.
-
-- Issue #1631171: Re-implement the 'warnings' module in C (the
- original Python code has been kept as backup). This will allow for
- using the 'warning's machinery in such places as the parser where
- use of pure Python code is not possible. Both the ``showarning()``
- and ``formatwarning()`` gain an optional 'line' argument which is
- not called by default for backwards-compatibility reasons. Setting
- ``warnings.showwarning()`` to an implementation that lacks support
- for the ``line`` argument will raise a DeprecationWarning.
-
-Library
--------
-
-- The audiodev module has been deprecated for removal in Python 3.0.
-
-- Issue #2750: Add the 'json' package. Based on simplejson 1.9 and
- contributed by Bob Ippolito.
-
-- Issue #1734346: Support Unicode file names for zipfiles.
-
-- Issue #2581: distutils: Vista UAC/elevation support for
- bdist_wininst.
-
-- Issue #2635: Fix bug in 'fix_sentence_endings' textwrap.fill option,
- where an extra space was added after a word containing (but not
- ending in) '.', '!' or '?'.
-
-- Add from_buffer() and from_buffer_copy() class methods to ctypes
- data types.
-
-- Issue #2682: ctypes callback functions no longer contain a cyclic
- reference to themselves.
-
-- The getpass module has been improved on Unix. It now uses /dev/tty
- by default and uses stderr instead of stdout. A GetPassWarning is
- issued when input echo cannot be controlled.
-
-- Issue #2014: Allow XML-RPC datetime objects to have dates before
- 1900-01-01.
-
-- Issue #2439: Added new function pkgutil.get_data(), which is a
- convenience wrapper for the PEP 302 get_data() API.
-
-- Issue #2616: The ctypes.pointer() and ctypes.POINTER() functions are
- now implemented in C for better performance.
-
-- Issue #2408: The ``_types`` module, which was used as in
- implementation detail of the public ``types`` module, has been
- removed and replaced by pure python code.
-
-- Issue #2513: distutils on Windows is now capable of cross-compiling
- extension modules between 32 and 64 bit platforms. See the distutls
- build documentation for more information.
-
-- Issue #815646: Individual file objects may now be used from multiple
- threads at once without fear of crashing the Python interpreter. If
- file.close() is called while an object is in use by another thread
- an IOError exception will be raised and the file will not be closed.
-
-- The bundled libffi copy is now in sync with the recently released
- libffi3.0.5 version, apart from some small changes to
- Modules/_ctypes/libffi/configure.ac.
-
-- Issue #2385: distutils.core.run_script() makes __file__ available,
- so the controlled environment will more closely mirror the typical
- script environment. This supports setup.py scripts that refer to
- data files.
-
-Tests
------
-
-- Issue #2550: The approach used by client/server code for obtaining
- ports to listen on in network-oriented tests has been refined in an
- effort to facilitate running multiple instances of the entire
- regression test suite in parallel without issue.
- test_support.bind_port() has been fixed such that it will always
- return a unique port -- which wasn't always the case with the
- previous implementation, especially if socket options had been set
- that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
- new implementation of bind_port() will actually raise an exception
- if it is passed an AF_INET/SOCK_STREAM socket with either the
- SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
- available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
- the socket it's been passed. This currently only applies to
- Windows. This option prevents any other sockets from binding to the
- host/port we've bound to, thus removing the possibility of the
- 'non-deterministic' behaviour, as Microsoft puts it, that occurs
- when a second SOCK_STREAM socket binds and accepts to a host/port
- that's already been bound by another socket. The optional preferred
- port parameter to bind_port() has been removed. Under no
- circumstances should tests be hard coding ports!
-
- test_support.find_unused_port() has also been introduced, which will
- pass a temporary socket object to bind_port() in order to obtain an
- unused port. The temporary socket object is then closed and
- deleted, and the port is returned. This method should only be used
- for obtaining an unused port in order to pass to an external program
- (i.e. the -accept [port] argument to openssl's s_server mode) or as
- a parameter to a server-oriented class that doesn't give you direct
- access to the underlying socket used.
-
- Finally, test_support.HOST has been introduced, which should be used
- for the host argument of any relevant socket calls (i.e. bind and
- connect).
-
- The following tests were updated to following the new conventions:
- test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
- test_poplib, test_ftplib, test_telnetlib, test_socketserver,
- test_asynchat and test_socket_ssl.
-
- It is now possible for multiple instances of the regression test
- suite to run in parallel without issue.

-
-*Release date: 02-Apr-2008*
-
-Core and builtins
------------------
-
-- Issue #1733757: The interpreter would hang on shutdown if the
- tracing function set by sys.settrace is still active and happens to
- call threading.currentThread().
-
-- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
- cannot be executed.
-
-- The compilation of a class nested in another class used to leak one
- reference on the outer class name.
-
-- Patch #1810: compile() can now compile _ast trees as returned by

- SMTP.quit().
-
-- Backport of Python 3.0's io module.
-
-- Issue #2482: Make sure that the coefficient of a Decimal is always

- the standard distribution.
-
-- Issue #1747858: Fix chown to work with large uid's and gid's on
- 64-bit platforms.
-
-- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different

-
-- Issue #1158: add %f format (fractions of a second represented as
- microseconds) to datetime objects. Understood by both strptime and
- strftime.
-
-- Issue #705836: struct.pack(">f", x) now raises OverflowError on all
- platforms when x is too large to fit into an IEEE 754 float;
- previously it only raised OverflowError on non IEEE 754 platforms.
-
-- Issues #2166, #1741 and #1531505: now distutils deals with HOME
- correctly under win32
-
-- Patch #1858: distutils: added multiple server support in .pypirc
-
-- Issue #1106316: pdb.post_mortem()'s parameter, "traceback", is now
- optional: it defaults to the traceback of the exception that is

- non- zero status code if not all files could be compiled
- successfully.
-
-- Bug #1725737: In distutils' sdist, exclude RCS, CVS etc. also in the
- root directory, and also exclude .hg, .git, .bzr, and _darcs.

-- Issue #1872: The struct module typecode for _Bool has been changed
- from 't' to '?'.
-
-- The bundled libffi copy is now in sync with the recently released
- libffi3.0.4 version, apart from some small changes to
- Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
- files are used. On all linux systems the --with-system-ffi
- configure option defaults to "yes".
-
-- Issue #1577: shutil.move() now calls os.rename() if the destination
- is a directory instead of copying-then-remove-source.

-
-What's New in Python 2.6 alpha 1?
-=================================
-
-*Release date: 29-Feb-2008*
-
-Core and builtins
------------------
-
-- Issue #2051: pyc and pyo files are no longer created with permission
- 644. The mode is now inherited from the py file.
-
-- Issue #2067: file.__exit__() now calls subclasses' close() method.
-
-- Patch #1759: Backport of PEP 3129 class decorators.
-
-- Issue #1881: An internal parser limit has been increased. Also see
- issue #215555 for a discussion.
-
-- Added the future_builtins module, which contains hex() and oct().
- These are the PEP 3127 version of these functions, designed to be
- compatible with the hex() and oct() builtins from Python 3.0. They
- differ slightly in their output formats from the existing, unchanged
- Python 2.6 builtins. The expected usage of the future_builtins
- module is:
- from future_builtins import hex, oct
-
-- Issue #1600: Modified PyOS_ascii_formatd to use at most 2 digit
- exponents for exponents with absolute value < 100. Follows C99
- standard. This is a change on Windows, which would use 3 digits.
- Also, added 'n' to the formats that PyOS_ascii_formatd understands,
- so that any alterations it does to the resulting string will be
- available in stringlib/formatter.h (for float.__format__).
-
-- Implemented PEP 3101, Advanced String Formatting. This adds a new
- builtin format(); a format() method for str and unicode; a
- __format__() method to object, str, unicode, int, long, float, and
- datetime; the class string.Formatter; and the C API
- PyObject_Format().
-
-- Fixed several potential crashes, all caused by specially crafted
- __del__ methods exploiting objects in temporarily inconsistent
- state.
-
-- Issue #2115: Important speedup in setting __slot__ attributes. Also
- prevent a possible crash: an Abstract Base Class would try to access
- a slot on a registered virtual subclass.
-
-- Fixed repr() and str() of complex numbers with infinity or nan as
- real or imaginary part.
-
-- Clear all free lists during a gc.collect() of the highest generation
- in order to allow pymalloc to free more arenas. Python may give back
- memory to the OS earlier.
-
-- Issue #2045: Fix an infinite recursion triggered when printing a
- subclass of collections.defaultdict, if its default_factory is set
- to a bound method.
-
-- Fixed a minor memory leak in dictobject.c. The content of the free
- list was not freed on interpreter shutdown.
-
-- Limit free list of method and built-in function objects to 256
- entries each.
-
-- Patch #1953: Added ``sys._compact_freelists()`` and the C API
- functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
- to compact the internal free lists of pre-allocted ints and floats.
-
-- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
- calls. Python expected the return type int but the fork familie
- returns pi_t.
-
-- Issue #1678380: Fix a bug that identifies 0j and -0j when they
- appear in the same code unit.
-
-- Issue #2025: Add tuple.count() and tuple.index() methods to comply
- with the collections.Sequence API.
-
-- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
- linebreak detection
-
-- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
- the internal lookup cache for ref leak tests.
-
-- Patch #1473257: generator objects gain a gi_code attribute. This is
- the same object as the func_code attribute of the function that
- produced the generator.
-
-- Issue #1920: "while 0" statements were completely removed by the
- compiler, even in the presence of an "else" clause, which is
- supposed to be run when the condition is false. Now the compiler
- correctly emits bytecode for the "else" suite.
-
-- A few crashers fixed: weakref_in_del.py (issue #1377858);
- loosing_dict_ref.py (issue #1303614, test67.py);
- borrowed_ref_[34].py (not in tracker).
-
-- Issue #1069410: The "can't load dll" message box on Windows is
- suppressed while an extension is loaded by calling SetErrorMode in
- dynload_win.c. The error is still reported properly.
-
-- Issue #1915: Python compiles with --enable-unicode=no again. However
- several extension methods and modules do not work without unicode
- support.
-
-- Issue #1882: when compiling code from a string, encoding cookies in the
- second line of code were not always recognized correctly.
-
-- Issue #1679: "0x" was taken as a valid integer literal.
-
-- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
- added.
-
-- sys.float_info / PyFloat_GetInfo: The floating point information
- object was converted from a dict to a specialized structseq object.
-
-- Patch #1816: Added sys.flags structseq. It exposes the status of
- most command line arguments and PYTHON* environment variables.
-
-- Objects/structseq.c: Implemented new structseq representation. The
- patch makes structseqs (e.g. the return value of os.stat) more
- readable.
-
-- Patch #1700288: added a type attribute cache that caches method
- accesses, resulting in speedups in heavily object-oriented code.
-
-- Bug #1776: __import__() no longer accepts filenames on any platform.
- The first parameter to __import__() must be a valid module name.
-
-- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
-
-- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
- envvar and sys.dont_write_bytecode attribute. All these can be set
- to forbid Python to attempt to write compiled bytecode files.
-
-- Improve some exception messages when Windows fails to load an
- extension module. Now we get for example '%1 is not a valid Win32
- application' instead of 'error code 193'.
-
-- Bug #1481296: Fixed long(float('nan')) != 0L.
-
-- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
- y) functions.
-
-- Issue #1635: Platform independent creation and representation of NaN
- and INF. float("nan"), float("inf") and float("-inf") now work on
- every platform with IEEE 754 semantics.
-
-- Compiler now generates simpler and faster code for dictionary
- literals. The oparg for BUILD_MAP now indicates an estimated
- dictionary size. There is a new opcode, STORE_MAP, for adding
- entries to the dictionary.
-
-- Issue #1638: %zd configure test fails on Linux.
-
-- Issue #1620: New property decorator syntax was modifying the
- decorator in place instead of creating a new decorator object.
-
-- Issue #1538: Avoid copying string in split/rsplit if the split char
- is not found.
-
-- Issue #1553: An erroneous __length_hint__ can make list() raise a
- SystemError.
-
-- PEP 366: Allow explicit relative imports when executing modules
- inside packages with the -m switch via a new module level
- __package__ attribute.
-
-- Issue #1402: Fix a crash on exit, when another thread is still
- running, and if the deallocation of its frames somehow calls the
- PyGILState_Ensure() / PyGILState_Release() functions.
-
-- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
-
-- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
- attribute of an empty cell object.
-
-- Issue #1460: The utf-7 incremental decoder did not accept truncated
- input. It now correctly saves its state between chunks of data.
-
-- Patch #1739468: Directories and zipfiles containing a __main__.py
- file can now be directly executed by passing their name to the
- interpreter. The directory/zipfile is automatically inserted as the
- first entry in sys.path.
-
-- Issue #1265: Fix a problem with sys.settrace, if the tracing
- function uses a generator expression when at the same time the
- executed code is closing a paused generator.
-
-- sets and frozensets now have an isdisjoint() method.
-
-- optimize the performance of builtin.sum().
-
-- Fix warnings found by the new version of the Coverity checker.
-
-- The enumerate() built-in function is no longer bounded to sequences
- smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
- automatically shifts from ints to longs.
-
-- Issue #1686386: Tuple's tp_repr did not take into account the
- possibility of having a self-referential tuple, which is possible
- from C code. Nor did object's tp_str consider that a type's tp_str
- could do something that could lead to an inifinite recursion.
- Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
- issues.
-
-- Issue #1164: It was possible to trigger deadlock when using the
- 'print' statement to write to a file since the GIL was not released
- as needed. Now PyObject_Print() does the right thing along with
- various tp_print implementations of the built-in types and those in
- the collections module.
-
-- Issue #1147: Exceptions were directly allowing string exceptions in
- their throw() method even though string exceptions no longer
- allowed.
-
-- Issue #1096: Prevent a segfault from getting the repr of a very
- deeply nested list by using the recursion counter.
-
-- Issue #1202533: Fix infinite recursion calls triggered by calls to
- PyObject_Call() never calling back out to Python code to trigger
- recursion depth updates/checks. Required the creation of a static
- RuntimeError instance in case normalizing an exception put the
- recursion check value past its limit. Fixes crashers
- infinite_rec_(1|2|4|5).py.
-
-- Patch #1031213: Decode source line in SyntaxErrors back to its
- original source encoding.
-
-- Patch #1673759: add a missing overflow check when formatting floats
- with %G.
-
-- Prevent expandtabs() on string and unicode objects from causing a
- segfault when a large width is passed on 32-bit platforms.
-
-- Issue #1733488: Fix compilation of bufferobject.c on AIX.
-
-- Issue #1722485: remove docstrings again when running with -OO.
-
-- Add new attribute names for function objects. All the func_* become
- __*__ attributes. (Some already existed, e.g., __doc__ and
- __name__.)
-
-- Add -3 option to the interpreter to warn about features that are
- deprecated and will be changed/removed in Python 3.0.
-
-- Patch #1686487: you can now pass any mapping after '**' in function
- calls.
-
-- except clauses may now be spelled either "except E, target:" or
- "except E as target:". This is to provide forwards compatibility
- with Python 3.0.
-
-- Deprecate BaseException.message as per PEP 352.
-
-- Issue #1303614: don't expose object's __dict__ when the dict is
- inherited from a built-in base.
-
-- When __slots__ are set to a unicode string, make it work the same as
- setting a plain string, ie don't expand to single letter identifiers.
-
-- Request #1191699: Slices can now be pickled.
-
-- Request #1193128: str.translate() now allows a None argument for
- translations that only remove characters without re-mapping the
- remaining characters.
-
-- Patch #1682205: a TypeError while unpacking an iterable is no longer
- masked by a generic one with the message "unpack non-sequence".
-
-- Remove unused file Python/fmod.c.
-
-- Bug #1683368: The object.__init__() and object.__new__() methods are
- now stricter in rejecting excess arguments. The only time when
- either allows excess arguments is when it is not overridden and the
- other one is. For backwards compatibility, when both are
- overridden, it is a deprecation warning (for now; maybe a Py3k
- warning later). Also, type.__init__() insists on the same signature
- as supported by type.__new__().
-
-- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
- object to complex using its __complex__() method before falling back
- to the __float__() method. Therefore, the functions in the cmath
- module now can operate on objects that define a __complex__()
- method.
-
-- Patch #1623563: allow __class__ assignment for classes with
- __slots__. The old and the new class are still required to have the
- same slot names.
-
-- Patch #1642547: Fix an error/crash when encountering syntax errors
- in complex if statements.
-
-- Patch #1462488: Python no longer segfaults when
- ``object.__reduce_ex__()`` is called with an object that is faking
- its type.
-
-- Patch #1680015: Don't modify __slots__ tuple if it contains a
- unicode name.
-
-- Patch #1444529: the builtin compile() now accepts keyword arguments.
-
-- Bug #1678647: write a newline after printing an exception in any
- case, even when converting the value to a string failed.
-
-- The dir() function has been extended to call the __dir__() method on
- its argument, if it exists. If not, it will work like before. This
- allows customizing the output of dir() in the presence of a
- __getattr__().
-
-- Patch #922167: Python no longer segfaults when faced with infinitely
- self-recursive reload() calls (as reported by bug #742342).
-
-- Patch #1675981: remove unreachable code from ``type.__new__()``
- method.
-
-- Patch #1491866: change the complex() constructor to allow
- parthensized forms. This means complex(repr(x)) now works instead of
- raising a ValueError.
-
-- Patch #703779: unset __file__ in __main__ after running a file. This
- makes the filenames the warning module prints much more sensible
- when a PYTHONSTARTUP file is used.
-
-- Variant of patch #697613: don't exit the interpreter on a SystemExit
- exception if the -i command line option or PYTHONINSPECT environment
- variable is given, but break into the interactive interpreter just
- like on other exceptions or normal program exit.
-
-- Patch #1638879: don't accept strings with embedded NUL bytes in
- long().
-
-- Bug #1674503: close the file opened by execfile() in an error
- condition.
-
-- Patch #1674228: when assigning a slice (old-style), check for the
- sq_ass_slice instead of the sq_slice slot.
-
-- When printing an unraisable error, don't print exceptions. before
- the name. This duplicates the behavior whening normally printing
- exceptions.
-
-- Bug #1653736: Properly discard third argument to
- slot_nb_inplace_power.
-
-- PEP 352: Raising a string exception now triggers a TypeError.
- Attempting to catch a string exception raises DeprecationWarning.
-
-- Bug #1377858: Fix the segfaulting of the interpreter when an object
- created a weakref on itself during a __del__ call for new-style
- classes (classic classes still have the bug).
-
-- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
- frame's thread state.
-
-- patch #1630975: Fix crash when replacing sys.stdout in
- sitecustomize.py.
-
-- Prevent seg fault on shutdown which could occur if an object raised
- a warning.
-
-- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main, to
- avoid relying on atexit.
-
-- Bug #1590891: random.randrange don't return correct value for big
- number.
-
-- Patch #1586791: Better exception messages for some operations on
- strings, tuples and lists.
-
-- Bug #1067760: Deprecate passing floats to file.seek.
-

-- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
- of w# format code incorrectly truncated the length to an int, even
- when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
- incorrect results with huge strings.
-
-- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
- Py_TYPE and Py_REFCNT.
-
-- PEP 3123: Provide forward compatibility with Python 3.0, while
- keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
- and PyVarObject_HEAD_INIT.
-
-- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
- defined.
-
-- Patch #1733960: Allow T_LONGLONG to accept ints.
-
-- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
-
-- Added a new API function ``PyImport_ImportModuleNoBlock``.
-
-- Bug #1637022: Prefix AST symbols with _Py_.
-
-- Fix some leftovers from the conversion from int to Py_ssize_t
- (relevant to strings and sequences of more than 2**31 items).
-
-- Make _PyGILState_NoteThreadState() static, it was not used anywhere
- outside of pystate.c and should not be necessary.
-
-- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
- absolute imports. In earlier versions they might have used relative
- imports under some conditions.
-
-- Added case insensitive comparison methods ``PyOS_stricmp(char*,
- char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
-
-- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
- macro so it can be used as an expression.
-
-Windows
--------
-
-- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
- requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
- macros are set to Win2k for x86/32bit builds and WinXP for AMD64
- builds.
-
-- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
- _CRT_NONSTDC_NO_DEPRECATE.
-
-- Bug #1216: Restore support for Visual Studio 2002.
-
-Mac
----
-
-- cfmfile now raises a DeprecationWarning.
-
-- buildtools now raises a DeprecationWarning.
-
-- Removed the macfs module. It had been deprecated since Python 2.5.
- This lead to the deprecation of macostools.touched() as it relied
- solely on macfs and was a no-op under OS X.
