Ned Deily18fae3f2013-01-31 01:24:55 -08001174- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1175 In particular, fix extension module build failures when trying to use
1176 32-bit-only installer Pythons on systems with Xcode 4 (currently
1177 OS X 10.8, 10.7, and optionally 10.6).
1178 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1179 * Since Xcode 4 removes ppc support, extension module builds now
1180 check for ppc compiler support and by default remove ppc and
1181 ppc64 archs when they are not available.
1182 * Extension module builds now revert to using system installed
1183 headers and libs (/usr and /System/Library) if the SDK used
1184 to build the interpreter is not installed or has moved.
1185 * Try to avoid building extension modules with deprecated
1186 and problematic Apple llvm-gcc compiler. If original compiler
1187 is not available, use clang instead by default.

1539 int.__pow__. These overflow checks were causing int.__pow__ to produce
1540 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001541 compiler optimizing the check away. Also fix similar overflow checks
1542 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01001612 has left two versions of customize_compiler, the original in
1613 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001618- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1619 Distutils-based packages with C extension modules may fail because
1620 Apple has removed gcc-4.2, the version used to build python.org
1621 64-bit/32-bit Pythons. If the user does not explicitly override
1622 the default C compiler by setting the CC environment variable,
1623 Distutils will now attempt to compile extension modules with clang
1624 if gcc-4.2 is required but not found. Also as a convenience, if
1625 the user does explicitly set CC, substitute its value as the default
1626 compiler in the Distutils LDSHARED configuration variable for OS X.
1627 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1628 SDK, neither of which are available in Xcode 4. This change does not
1629 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001879- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1880 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1881 interpreter process. This could cause failures in non-Distutils subprocesses
1882 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001883 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001884 deployment target only in the environment of each build subprocess. It is
1885 still possible to globally override the default by setting
1886 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1887 greater or equal to the default value, the value with which the interpreter
1888 was built.

1917 updating the check interval, so if the user decreases the check interval,
1918 the ticker doesn't have to wind down to zero from the old starting point
1919 before the new interval takes effect. And if the user increases the
1920 interval, it makes sure the new limit takes effect right away rather have an
1921 early task switch before recognizing the new interval.

2903 becoming permanently uncollectable GC garbage. The downside is that
2904 removing __del__ means that the internal doubly-linked list has to wait for
2905 GC collection rather than freeing memory immediately when the refcnt drops

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003365- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3366 start byte and the continuation byte(s) are now considered invalid, instead
3367 of the number of bytes specified by the start byte.
3368 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3369 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3370 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

3380 objects. (1) The comparison could incorrectly return True in some cases
3381 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3382 (2) The comparison raised an OverflowError for large integers, leading

3578 operation raises multiple signals and more than one of those signals is
3579 trapped, the specification determines the order in which the signals should be
3580 handled. In many cases this order wasn't being followed, leading to the wrong

Georg Brandlfee0f442010-05-22 21:26:21 +00003725- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003726 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3727 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3728 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3750
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003751- Issue #7301: Add environment variable $PYTHONWARNINGS.
3752
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003753- Issue #8329: Don't return the same lists from select.select when no fds are
3754 changed.
3755
Georg Brandlfee0f442010-05-22 21:26:21 +00003756- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003757 on 64-bit machines. The shift count for either left or right shift is
3758 permitted to be up to sys.maxsize.
3759
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003760- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003764- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3765
Georg Brandlfee0f442010-05-22 21:26:21 +00003766- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3767 with a non-empty format string. This is an effort to future-proof user
3768 code. If a derived class does not currently implement __format__ but later
3769 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003770 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003771 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003772
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003773- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003786- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003787 (SIGINT). If an error occurs while importing the site module, the error is
3788 printed and Python exits. Initialize the GIL before importing the site

Antoine Pitrouf9de5342010-04-05 21:35:07 +00003798- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00003799 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

3803
Georg Brandlfee0f442010-05-22 21:26:21 +00003804- Issue #8257: The Decimal construct now accepts a float instance directly,
3805 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003806
3807 >>> Decimal(1.1)
3808 Decimal('1.100000000000000088817841970012523233890533447265625')
3809
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003810- collections.Counter() now supports a subtract() method.
3811
Georg Brandlfee0f442010-05-22 21:26:21 +00003812- The functools module now has a total_ordering() class decorator to simplify
3813 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003814
Georg Brandlfee0f442010-05-22 21:26:21 +00003815- The functools module also adds cmp_to_key() as a tool to transition old-style
3816 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003817
Georg Brandlfee0f442010-05-22 21:26:21 +00003818- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3819 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003820
Georg Brandlfee0f442010-05-22 21:26:21 +00003821- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3822 InvalidOperation instead of returning False. (Comparisons involving a quiet
3823 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3824 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003825
Georg Brandlfee0f442010-05-22 21:26:21 +00003826- Issue #2531: Comparison operations between floats and Decimal instances now
3827 return a result based on the numeric values of the operands; previously they
3828 returned an arbitrary result based on the relative ordering of id(float) and
3829 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003830
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003831- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003832 argument `-` which tells it to read files to compile from stdin. Each line is
3833 read on demand and the named file is compiled immediately. (Original patch by
3834 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003835
Georg Brandlfee0f442010-05-22 21:26:21 +00003836- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3837 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003839- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3840 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003841 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003842
Georg Brandlfee0f442010-05-22 21:26:21 +00003843- Comparisons using one of <, <=, >, >= between a complex instance and a
3844 Fractions instance now raise TypeError instead of returning True/False. This
3845 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3846 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003847

Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003861- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3862 deprecated.
3863
Georg Brandlfee0f442010-05-22 21:26:21 +00003864- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003901- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003902 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3903 log file to compute the next rollover time. If the log file does not exist,
3904 the current time is used as the basis for the computation.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003945- Issue #8300: When passing a non-integer argument to struct.pack with any
3946 integer format code, struct.pack first attempts to convert the non-integer
3947 using its __index__ method. If that method is non-existent or raises
3948 TypeError it goes on to try the __int__ method, as described below.
3949
Georg Brandlba83f822010-03-14 09:50:54 +00003950- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3951 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3952 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003953 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3954 inconsistent: __int__ was used for some integer codes but not for others, and
3955 the set of integer codes for which it was used differed between native packing

4188 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004189 library would return a bogus result; on Solaris, it was possible to crash the

4210 returning NULL. The macro now returns a statically allocated empty string
4211 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004264 file position when calling `truncate()`. It would previously change the file
4265 position to the given argument, which goes against the tradition of

4269 class used to represent files stored inside an archive. The new
4270 implementation is significantly faster and can be wrapped in a
4271 ``io.BufferedReader`` object for more speedups. It also solves an issue
4272 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4285 encoded string for them. This ensures that the upload and register commands
4286 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004363- The ``__complex__()`` method is now looked up on the class of instances to
4364 make it consistent with other special methods.

4368
Mark Dickinson1b34d252010-01-01 17:27:30 +00004369- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004370 DeprecationWarning when passed a float argument where an integer was expected.
4371 These functions and methods now raise TypeError instead. The majority of the
4372 effects of this change are in the extension modules, but some core functions
4373 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4374 and many unicode/str methods.

4388 of integers: the result of a/b is now correctly rounded for ints a and b (at
4389 least on IEEE 754 platforms), and in particular does not depend on the
4390 internal representation of a long.

4398
Georg Brandlba83f822010-03-14 09:50:54 +00004399 These executables now work properly with the arch(1) command: ``arch -ppc
4400 python`` will start a universal binary version of python in PPC mode (unlike

4541 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004542
Georg Brandlba83f822010-03-14 09:50:54 +00004543- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4544 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004545
Georg Brandlba83f822010-03-14 09:50:54 +00004546- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4547 1e-100 used to raise OverflowError, but now gives the requested 120
4548 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004557- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4558 decimal string that's guaranteed to round back to x under correct rounding
4559 (with round-half-to-even rounding mode). Previously it gave a string based on
4560 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4561 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4562 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004563
Georg Brandlba83f822010-03-14 09:50:54 +00004564- Issue #7117: On almost all platforms: float-to-string and string-to-float
4565 conversions within Python are now correctly rounded. Places these conversions
4566 occur include: str for floats and complex numbers; the float and complex
4567 constructors; old-style and new-style numeric formatting; serialization and
4568 deserialization of floats and complex numbers using marshal, pickle and json;
4569 parsing of float and imaginary literals in Python code; Decimal-to-float
4570 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004571
Georg Brandlba83f822010-03-14 09:50:54 +00004572 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4573 providing correctly-rounded strtod and dtoa C functions. This code is
4574 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4575 the C compiler. There may be a small number of platforms on which correct
4576 operation of this code cannot be guaranteed, so the code is not used: notably,
4577 this applies to platforms where the C double format is not IEEE 754 binary64,
4578 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4579 and Python's configure script is unable to determine how to change the FPU
4580 precision. On these platforms conversions use the platform strtod and dtoa,
4581 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004582
Georg Brandlba83f822010-03-14 09:50:54 +00004583- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4584 uses the correctly-rounded string <-> float conversions described above (when
4585 available), and so produces correctly rounded results that will display nicely
4586 under the float repr. There are two related small changes: (1) round now
4587 accepts any class with an ``__index__()`` method for its second argument (but
4588 no longer accepts floats for the second argument), and (2) an excessively
4589 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4590 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004732
Georg Brandlba83f822010-03-14 09:50:54 +00004733 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4734 (2) parsing of strings representing infinities and nans was locale aware; and
4735 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004737- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4738 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4739 but with at least one decimal point and with a default precision
4740 of 12. Previously, the behavior the same but with a default precision of 6.
4741 This more closely matches ``str()``, and reduces surprises when adding
4742 alignment flags to the empty presentation type. This also affects the new
4743 complex.__format__ in the same way.
4744
4745- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4746 classtype's, even if it was None. property now inserts the __doc__ into the

4817 internal representation of integers, for performance reasons. Base 2**30 is
4818 enabled by default on 64-bit machines. Add --enable-big-digits option to

4905
Georg Brandl6425a2f2008-12-28 11:54:53 +00004906- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004907 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00004908
Skip Montanarof205c132008-12-23 03:30:15 +00004909- Added test case to ensure attempts to read from a file opened for writing
4910 fail.
4911
Georg Brandlba83f822010-03-14 09:50:54 +00004912- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print

Georg Brandlba83f822010-03-14 09:50:54 +00004926- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4927 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4928 instances. On a typical machine this saves 3 bytes of memory (on average) per
4929 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004931- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4932 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4933 instead of throwing a MemoryError.
4934
Georg Brandlba83f822010-03-14 09:50:54 +00004935- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00004938- Issue #4367: Python would segfault during compiling when the unicodedata

4940
Georg Brandlba83f822010-03-14 09:50:54 +00004941- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4942 file objects with closefd=False. The file descriptor is still kept open but
4943 the file object behaves like a closed file. The ``FileIO`` object also got a
4944 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004946- Issue #4348: Some bytearray methods returned that didn't cause any change to
4947 the bytearray, returned the same bytearray instead of a copy.
4948
Georg Brandlba83f822010-03-14 09:50:54 +00004949- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00004961- Issue #4209: Enabling unicode_literals and the print_function in the same
4962 __future__ import didn't work.
4963
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004964- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004965 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004966
Georg Brandlba83f822010-03-14 09:50:54 +00004967- On windows, ``os.chdir()`` given unicode was not working if
4968 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4969 this code path is really executed because I cannot move to such directory on
4970 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004971
Georg Brandlba83f822010-03-14 09:50:54 +00004972- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4973 element is temporarily replaced with an equivalent frozenset. But the
4974 eventual KeyError would always report the empty ``frozenset()`` as the missing
4975 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004992- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4993 returned them on 64bit platforms.
4994
Walter Dörwalded960ac2009-05-03 22:36:33 +00004995- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4996 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4997 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4998 of using the replace error handler in PyUnicode_DecodeUTF8().
4999
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005000- Issue #3739: The unicode-internal encoder now reports the number of characters
5001 consumed like any other encoder (instead of the number of bytes).
5002
Georg Brandlba83f822010-03-14 09:50:54 +00005003- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5004 allocator will be automatically disabled when running under Valgrind. This
5005 gives improved memory leak detection when running under Valgrind, while taking
5006 advantage of pymalloc at other times.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00006251- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6252 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006253 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6254 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00006259- Issue #5354: New test support function import_fresh_module() makes it easy to
6260 import both normal and optimised versions of modules. test_heapq and
6261 test_warnings have been adjusted to use it, tests for other modules with both
6262 C and Python implementations in the stdlib can be adjusted to use it over
6263 time.

6272 should cause a test to be skipped are now done using import_module from test
6273 support, which does the conversion.

6375
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006376- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6377 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6378 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6379 ``printf`` function, whereas PyString_FromFormat has an independent
6380 implementation and uses "%zd" on all platforms for size_t values.
6381 This makes a difference on win64, where ``printf`` needs "%Id" to display
6382 64bit values.

6388 object; previously an int would be returned for small values. the __long__
6389 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006399 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006401- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006402 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6403 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6404 when given a tuple of classes as second argument, were looking up
6405 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6406 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006545What's New in Python 2.6 beta 3?
6546================================
6547
Barry Warsaw07a4a382008-08-21 01:15:08 +00006548*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006549
6550Core and Builtins
6551-----------------
6552
Guido van Rossumf8402962008-08-20 15:01:50 +00006553- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6554 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6555 extensions do not automatically benefit from the class attribute
6556 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6557 to their tp_flags field if they care. This is a backwards
6558 compatibility feature; in 3.0, all types will use the cache by
6559 default.
6560
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006561- Keyword arguments can now follow starred arguments. (``f(a, *args,
6562 keyword=23)`` is now valid syntax.)
6563
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006564- ctypes function pointers that are COM methods have a boolean True
6565 value again.
6566
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006567- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6568 by denying s# to parse objects that have a releasebuffer procedure,
6569 and introducing s*.
6570
Georg Brandl1e13ea92008-08-11 09:07:59 +00006571- Issue #3537: Fix an assertion failure when an empty but presized dict
6572 object was stored in the freelist.
6573
Mark Dickinsonb6467572008-08-04 21:30:09 +00006574- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6575 ValueError consistently across platforms.
6576
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006577- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6578 (64bit Unix, for example), unichr() would truncate its argument and return
6579 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6580
Neal Norwitze7d8be82008-07-31 17:17:14 +00006581- Apply security patches from Apple.
6582
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006583- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6584 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6585
Antoine Pitrou92f82162008-07-25 22:22:08 +00006586- Issue #1819: function calls with several named parameters are now on
6587 average 35% faster (as measured by pybench).
6588
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006589- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6590 the python debugger steps into a class statement: the free variables (local
6591 variables defined in an outer scope) would be deleted from the outer scope.
6592
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006593- Issue #2620: Overflow checking when allocating or reallocating memory
6594 was not always being done properly in some python types and extension
6595 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6596 all been updated to perform better checks and places in the code that
6597 would previously leak memory on the error path when such an allocation
6598 failed have been fixed.
6599
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006600Library
6601-------
6602
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006603- Issue #3612: Added some missing basic types in ctypes.wintypes.
6604
Benjamin Petersone977ad42008-08-20 01:42:01 +00006605- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6606 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6607
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006608- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6609 version reported by these tools does not necessarily follow the python
6610 version numbering scheme, so the module is less strict when parsing it.
6611
Nick Coghlanf70385a2008-08-18 12:42:46 +00006612- Issue #2235: Added Py3k warnings for types which will become unhashable
6613 under the stricter __hash__ inheritance rules in 3.0. Several types
6614 which did not meet the rules for hash invariants and were already
6615 unhashable in 3.0 have now been explicitly flagged as unhashable in
6616 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6617 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6618
Brett Cannon88f801d2008-08-18 00:46:22 +00006619- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6620 imported into the module but exposed as part of the module's API.
6621
Brett Cannon7b96f072008-08-18 00:41:11 +00006622- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6623
Brett Cannon46225e72008-08-18 00:36:52 +00006624- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6625
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006626- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6627
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006628- Issue #3575: Incremental decoder's decode function now takes bytearray
6629 by using 's*' instead of 't#'.
6630
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006631- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006632 fails unicode conversion on 2nd parameter. (windows only)
6633
Georg Brandl222e2082010-08-01 22:27:39 +00006634- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006635 in a redirect.
6636
Brett Cannonabe423e2008-08-16 21:47:07 +00006637- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006638 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006639
Facundo Batistaeb90b782008-08-16 14:44:07 +00006640- Issue #2776: fixed small issue when handling an URL with double slash
6641 after a 302 response in the case of not going through a proxy.
6642
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006643- Issue #2676: in the email package, content-type parsing was hanging on
6644 pathological input because of quadratic or exponential behaviour of a
6645 regular expression.
6646
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006647- Issue #3476: binary buffered reading through the new "io" library is now
6648 thread-safe.
6649
Brett Cannonbf3157b2008-08-14 05:00:03 +00006650- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6651 since mimetools itself is deprecated. Because modules are cached, all
6652 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6653
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006654- Issue #3134: shutil referenced undefined WindowsError symbol.
6655
Robert Schuppenies14646332008-08-10 11:01:53 +00006656- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6657 menu entries were not deleted.
6658
Brett Cannon83e81842008-08-09 23:30:55 +00006659- Copied the implementation of reduce() to _functools.reduce() to have a
6660 version that did not raise a DeprecationWarning under -3.
6661
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006662- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6663 a MemoryError rather than silently stop the iteration.
6664
Guido van Rossum59ce9012008-08-09 14:55:34 +00006665- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6666 to _sre.compile() will now be rejected. This should not affect anybody
6667 since the re.compile() function never generates invalid re-bytecode.
6668
Skip Montanaroa032bf42008-08-08 22:52:51 +00006669- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6670 upon first access it can be automatically initialized from the csv file if
6671 it wasn't initialized during instantiation.
6672
Brett Cannon3aa2a492008-08-06 22:28:09 +00006673- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6674 the reload() built-in has been removed.
6675
Brett Cannon7e30b672008-08-04 21:52:25 +00006676- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006677 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00006678 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
6679 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
6680 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
6681 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
6682 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00006683
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00006684- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
6685 raised an AttributeError.
6686
Benjamin Peterson01a24322008-07-28 23:35:27 +00006687- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006688 asking for a specific length. This problem only affected files opened
6689 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006690
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006691- Issue #3449: Update decimal module to use most recent specification
6692 (v. 1.68) and tests (v. 2.58) from IBM.
6693
Georg Brandl222e2082010-08-01 22:27:39 +00006694- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00006695
Georg Brandl222e2082010-08-01 22:27:39 +00006696- Issue #1592: Improve error reporting when operations are attempted
Raymond Hettinger8c664e82008-07-25 18:43:33 +00006697 on a closed shelf.
6698
Georg Brandlf9efabb2008-07-23 15:16:45 +00006699- Deprecate the "ast" parser function aliases.
6700
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006701- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
6702
6703- Issue #3303: Fix a crash in locale.strcoll() when calling it with
6704 invalid arguments.
6705
6706- Issue #3302: Fix several crashes when calling locale's gettext functions
6707 with None arguments.
6708
6709- Issue #3389: Allow resolving dotted names for handlers in logging
6710 configuration files.
6711
6712- Deprecate the sunaudio module for removal in Python 3.0.
6713
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006714- Issue #3394: zipfile.writestr sets external attributes when passed a
6715 file name rather than a ZipInfo instance, so files are extracted with
6716 mode 0600 rather than 000 under Unix.
6717
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006718- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6719 argument in python 2.5, this broke code that subclassed Popen to include its
6720 own poll method. Fixed my moving _deadstate to an _internal_poll method.
6721
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00006722Build
6723-----

6728-------------
6729
Nick Coghlan6e8fef02008-08-18 13:14:22 +00006730- Issue #2235: the C API function PyObject_HashNotImplemented and its
6731 interaction with the tp_hash slot (added in 2.6b2) are now documented
6732
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006733- Issue #643841: The language reference now provides more detailed
6734 coverage of the lookup process for special methods. The disclaimers
6735 regarding lack of coverage of new-style classes have also been
6736 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006739What's New in Python 2.6 beta 2?
6740================================
6741
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006742*Release date: 17-Jul-2008*
6743
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006744Core and Builtins
6745-----------------
6746
Georg Brandl3e483f62008-07-16 22:57:41 +00006747- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6748 its methods now allow for items objects that can be converted to
6749 an integer using operator.index().
6750
Mark Dickinson64b7e502008-07-16 09:40:03 +00006751- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6752 produced a ValueError instead of giving the correct float.
6753
Eric Smitha5fa5a22008-07-16 00:11:49 +00006754- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6755 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6756
Mark Dickinson7103aa42008-07-15 19:08:33 +00006757- Issue #3008: the float type has a new instance method 'float.hex'
6758 and a new class method 'float.fromhex' to convert floating-point
6759 numbers to and from hexadecimal strings, respectively.
6760
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006761- Issue #2235: __hash__ is once again inherited by default. To allow
6762 collections.Hashable to remain meaningful in the presence of the
6763 default hash implementation (object.__hash__), it is now possible
6764 to explicit block inheritance of hash by setting __hash__=None at
6765 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6766 level.
6767
Nick Coghlanb028f502008-07-13 14:52:36 +00006768- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6769 the parent module cannot be found while performing an absolute import.
6770 This means that an incorrectly defined __package__ attribute will
6771 now only prevent relative imports in that module rather than causing
6772 all imports from that module to fail.
6773
Nick Coghlan14ff9942008-07-08 14:21:42 +00006774- Issue #2517: Allow unicode messages in Exceptions again by correctly
6775 bypassing the instance dictionary when looking up __unicode__ on
6776 new-style classes.
6777
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006778- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6779 set to a custom object whose write() method happens to install
6780 another file in sys.stdout.
6781
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006782- Issue #3088: Corrected a race condition in classes derived from
6783 threading.local: the first member set by a thread could be saved in
6784 another thread's dictionary.
6785
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006786- Issue #3004: Minor change to slice.indices(): the start and stop
6787 arguments are now treated identically, making the behaviour easier
6788 to describe and understand. For example, slice(None, -10,
6789 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6790 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6791 10, -1).
6792
Georg Brandl278fc502008-07-19 12:46:12 +00006793- Issue #3219: Calling a function with repeated keyword arguments,
6794 f(a=2, a=23), would not cause a syntax error. This was a regression
6795 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006796
Georg Brandl278fc502008-07-19 12:46:12 +00006797- Issue #2862: Make int and float freelist management consistent with
6798 other freelists. Changes their CompactFreeList apis into
6799 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006800

6803
Thomas Heller57adf222008-08-14 19:10:48 +00006804- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6805 api functions without holding the GIL, which could lead to a fatal
6806 error when they failed.
6807
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006808- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6817 ForkingPickler.register() to resolve conflict with ctypes.
6818
Vinay Sajip51e65192008-07-18 09:01:10 +00006819- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

6822 a valid dlerror() message.
6823
Thomas Heller2bad6572008-07-15 17:19:50 +00006824- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6825 incomplete structure was created.

7244 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007245 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007246
7247 This is controlled by the configure argument ``--with-universal-archs``:
7248
7249 - ``--with-universal-archs=all``: install 4-way universal
7250
7251 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7252
7253 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7254
7255 This option should be used in combination with ``--enable-universalsdk=``.
7256
7257 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007307- Issue #1631171: Re-implement the 'warnings' module in C (the
7308 original Python code has been kept as backup). This will allow for
7309 using the 'warning's machinery in such places as the parser where
7310 use of pure Python code is not possible. Both the ``showarning()``
7311 and ``formatwarning()`` gain an optional 'line' argument which is
7312 not called by default for backwards-compatibility reasons. Setting
7313 ``warnings.showwarning()`` to an implementation that lacks support
7314 for the ``line`` argument will raise a DeprecationWarning.

7338
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007339- The getpass module has been improved on Unix. It now uses /dev/tty
7340 by default and uses stderr instead of stdout. A GetPassWarning is
7341 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007356- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007357 extension modules between 32 and 64 bit platforms. See the distutls

7379 effort to facilitate running multiple instances of the entire
7380 regression test suite in parallel without issue.
7381 test_support.bind_port() has been fixed such that it will always
7382 return a unique port -- which wasn't always the case with the
7383 previous implementation, especially if socket options had been set
7384 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7385 new implementation of bind_port() will actually raise an exception
7386 if it is passed an AF_INET/SOCK_STREAM socket with either the
7387 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7388 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7389 the socket it's been passed. This currently only applies to
7390 Windows. This option prevents any other sockets from binding to the
7391 host/port we've bound to, thus removing the possibility of the
7392 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7393 when a second SOCK_STREAM socket binds and accepts to a host/port
7394 that's already been bound by another socket. The optional preferred
7395 port parameter to bind_port() has been removed. Under no
7396 circumstances should tests be hard coding ports!
7397
7398 test_support.find_unused_port() has also been introduced, which will
7399 pass a temporary socket object to bind_port() in order to obtain an
7400 unused port. The temporary socket object is then closed and
7401 deleted, and the port is returned. This method should only be used
7402 for obtaining an unused port in order to pass to an external program
7403 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7404 a parameter to a server-oriented class that doesn't give you direct
7405 access to the underlying socket used.
7406
7407 Finally, test_support.HOST has been introduced, which should be used
7408 for the host argument of any relevant socket calls (i.e. bind and
7409 connect).

7411 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007412 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007413 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7414 test_asynchat and test_socket_ssl.
7415
Georg Brandl3ee81df2008-05-17 18:14:43 +00007416 It is now possible for multiple instances of the regression test
7417 suite to run in parallel without issue.

7684-----------------
7685
Fred Drakea8ee94b2008-03-01 02:45:07 +00007686- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007687 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007688
Georg Brandlad61bc82008-02-23 15:11:18 +00007689- Issue #2067: file.__exit__() now calls subclasses' close() method.
7690
7691- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007692
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007693- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007694 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007695
Eric Smitha73fbe72008-02-23 03:09:44 +00007696- Added the future_builtins module, which contains hex() and oct().
7697 These are the PEP 3127 version of these functions, designed to be
7698 compatible with the hex() and oct() builtins from Python 3.0. They
7699 differ slightly in their output formats from the existing, unchanged
7700 Python 2.6 builtins. The expected usage of the future_builtins
7701 module is:
7702 from future_builtins import hex, oct
7703
Eric Smith7ef40bf2008-02-20 23:34:22 +00007704- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7705 exponents for exponents with absolute value < 100. Follows C99
7706 standard. This is a change on Windows, which would use 3 digits.
7707 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7708 so that any alterations it does to the resulting string will be
7709 available in stringlib/formatter.h (for float.__format__).
7710
Eric Smith5a3c1352008-02-19 13:21:56 +00007711- Implemented PEP 3101, Advanced String Formatting. This adds a new
7712 builtin format(); a format() method for str and unicode; a
7713 __format__() method to object, str, unicode, int, long, float, and
7714 datetime; the class string.Formatter; and the C API
7715 PyObject_Format().
7716
Georg Brandl3ee81df2008-05-17 18:14:43 +00007717- Fixed several potential crashes, all caused by specially crafted
7718 __del__ methods exploiting objects in temporarily inconsistent
7719 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007720
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007721- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007722 prevent a possible crash: an Abstract Base Class would try to access
7723 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007724
Georg Brandl3ee81df2008-05-17 18:14:43 +00007725- Fixed repr() and str() of complex numbers with infinity or nan as
7726 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007727
Georg Brandl3ee81df2008-05-17 18:14:43 +00007728- Clear all free lists during a gc.collect() of the highest generation
7729 in order to allow pymalloc to free more arenas. Python may give back
7730 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007731
Georg Brandl3ee81df2008-05-17 18:14:43 +00007732- Issue #2045: Fix an infinite recursion triggered when printing a
7733 subclass of collections.defaultdict, if its default_factory is set
7734 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007735
Christian Heimesf75dbef2008-02-08 00:11:31 +00007736- Fixed a minor memory leak in dictobject.c. The content of the free
7737 list was not freed on interpreter shutdown.
7738
Georg Brandl21e99f42010-03-07 15:23:59 +00007739- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007740 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007741
Georg Brandl3ee81df2008-05-17 18:14:43 +00007742- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7743 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007744 to compact the internal free lists of pre-allocted ints and floats.
7745
Georg Brandl3ee81df2008-05-17 18:14:43 +00007746- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7747 calls. Python expected the return type int but the fork familie
7748 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007749
Georg Brandl3ee81df2008-05-17 18:14:43 +00007750- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7751 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007752
Georg Brandl3ee81df2008-05-17 18:14:43 +00007753- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7754 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007755
Georg Brandl3ee81df2008-05-17 18:14:43 +00007756- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7757 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007758
Georg Brandl3ee81df2008-05-17 18:14:43 +00007759- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7760 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007761
Georg Brandl3ee81df2008-05-17 18:14:43 +00007762- Patch #1473257: generator objects gain a gi_code attribute. This is
7763 the same object as the func_code attribute of the function that
7764 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007765
Georg Brandl3ee81df2008-05-17 18:14:43 +00007766- Issue #1920: "while 0" statements were completely removed by the
7767 compiler, even in the presence of an "else" clause, which is
7768 supposed to be run when the condition is false. Now the compiler
7769 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007770
Guido van Rossumeead05f2008-01-24 18:21:02 +00007771- A few crashers fixed: weakref_in_del.py (issue #1377858);
7772 loosing_dict_ref.py (issue #1303614, test67.py);
7773 borrowed_ref_[34].py (not in tracker).
7774
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007775- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007776 suppressed while an extension is loaded by calling SetErrorMode in
7777 dynload_win.c. The error is still reported properly.
7778
Georg Brandl3ee81df2008-05-17 18:14:43 +00007779- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007780 several extension methods and modules do not work without unicode
7781 support.
7782
Georg Brandl26543b12008-01-21 18:36:51 +00007783- Issue #1882: when compiling code from a string, encoding cookies in the
7784 second line of code were not always recognized correctly.
7785
Georg Brandl14404b62008-01-19 19:27:05 +00007786- Issue #1679: "0x" was taken as a valid integer literal.
7787
Georg Brandl6caad7d2008-01-26 14:19:22 +00007788- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007789 added.
7790
Christian Heimesc94e2b52008-01-14 04:13:37 +00007791- sys.float_info / PyFloat_GetInfo: The floating point information
7792 object was converted from a dict to a specialized structseq object.
7793
Georg Brandl3ee81df2008-05-17 18:14:43 +00007794- Patch #1816: Added sys.flags structseq. It exposes the status of
7795 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007796
Georg Brandl3ee81df2008-05-17 18:14:43 +00007797- Objects/structseq.c: Implemented new structseq representation. The
7798 patch makes structseqs (e.g. the return value of os.stat) more
7799 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007800
Georg Brandl3ee81df2008-05-17 18:14:43 +00007801- Patch #1700288: added a type attribute cache that caches method
7802 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007803
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007804- Bug #1776: __import__() no longer accepts filenames on any platform.
7805 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007806

7808
Georg Brandl3ee81df2008-05-17 18:14:43 +00007809- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7810 envvar and sys.dont_write_bytecode attribute. All these can be set
7811 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007812
Georg Brandl3ee81df2008-05-17 18:14:43 +00007813- Improve some exception messages when Windows fails to load an
7814 extension module. Now we get for example '%1 is not a valid Win32
7815 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007816
Georg Brandl3ee81df2008-05-17 18:14:43 +00007817- Bug #1481296: Fixed long(float('nan')) != 0L.

7820 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007821
Christian Heimes0a8143f2007-12-18 23:22:54 +00007822- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007823 and INF. float("nan"), float("inf") and float("-inf") now work on
7824 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007825
Georg Brandl3ee81df2008-05-17 18:14:43 +00007826- Compiler now generates simpler and faster code for dictionary
7827 literals. The oparg for BUILD_MAP now indicates an estimated
7828 dictionary size. There is a new opcode, STORE_MAP, for adding
7829 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007863- Issue #1265: Fix a problem with sys.settrace, if the tracing
7864 function uses a generator expression when at the same time the
7865 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007866
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007867- sets and frozensets now have an isdisjoint() method.
7868

7872
Georg Brandl21e99f42010-03-07 15:23:59 +00007873- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007874 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7875 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007876
Georg Brandl3ee81df2008-05-17 18:14:43 +00007877- Issue #1686386: Tuple's tp_repr did not take into account the
7878 possibility of having a self-referential tuple, which is possible
7879 from C code. Nor did object's tp_str consider that a type's tp_str
7880 could do something that could lead to an inifinite recursion.
7881 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7882 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007884- Issue #1164: It was possible to trigger deadlock when using the
7885 'print' statement to write to a file since the GIL was not released
7886 as needed. Now PyObject_Print() does the right thing along with
7887 various tp_print implementations of the built-in types and those in
7888 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007889
Georg Brandl3ee81df2008-05-17 18:14:43 +00007890- Issue #1147: Exceptions were directly allowing string exceptions in
7891 their throw() method even though string exceptions no longer
7892 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007893
Georg Brandl3ee81df2008-05-17 18:14:43 +00007894- Issue #1096: Prevent a segfault from getting the repr of a very
7895 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007896
Brett Cannon1e534b52007-09-07 04:18:30 +00007897- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007898 PyObject_Call() never calling back out to Python code to trigger
7899 recursion depth updates/checks. Required the creation of a static
7900 RuntimeError instance in case normalizing an exception put the
7901 recursion check value past its limit. Fixes crashers
7902 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007903
Georg Brandl3ee81df2008-05-17 18:14:43 +00007904- Patch #1031213: Decode source line in SyntaxErrors back to its

7908 with %G.
7909
Georg Brandl3ee81df2008-05-17 18:14:43 +00007910- Prevent expandtabs() on string and unicode objects from causing a
7911 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007912
Georg Brandl3ee81df2008-05-17 18:14:43 +00007913- Issue #1733488: Fix compilation of bufferobject.c on AIX.
Martin v. Löwisda587ab2007-06-08 17:29:20 +00007914
Georg Brandl3ee81df2008-05-17 18:14:43 +00007915- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00007916
Neal Norwitz0ac60192007-05-27 04:08:54 +00007917- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007918 __*__ attributes. (Some already existed, e.g., __doc__ and
7919 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007920
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007921- Add -3 option to the interpreter to warn about features that are
7922 deprecated and will be changed/removed in Python 3.0.
7923
Georg Brandl2134e752007-05-21 20:34:16 +00007924- Patch #1686487: you can now pass any mapping after '**' in function
7925 calls.
7926
Collin Winter62903052007-05-18 23:11:24 +00007927- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007928 "except E as target:". This is to provide forwards compatibility
7929 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007930
Brett Cannon229cee22007-05-05 01:34:02 +00007931- Deprecate BaseException.message as per PEP 352.
7932
Georg Brandl3ee81df2008-05-17 18:14:43 +00007933- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007934 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007935
Vinay Sajip8549ce32007-05-06 17:53:37 +00007936- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007937 setting a plain string, ie don't expand to single letter identifiers.
7938
Raymond Hettinger13936692007-04-11 18:40:58 +00007939- Request #1191699: Slices can now be pickled.
7940
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007941- Request #1193128: str.translate() now allows a None argument for
7942 translations that only remove characters without re-mapping the
7943 remaining characters.
7944
Georg Brandl5cb76c12007-03-21 09:00:39 +00007945- Patch #1682205: a TypeError while unpacking an iterable is no longer
7946 masked by a generic one with the message "unpack non-sequence".
7947
Neal Norwitzaa754b72007-03-21 06:39:48 +00007948- Remove unused file Python/fmod.c.
7949
Guido van Rossum143b5642007-03-23 04:58:42 +00007950- Bug #1683368: The object.__init__() and object.__new__() methods are
7951 now stricter in rejecting excess arguments. The only time when
7952 either allows excess arguments is when it is not overridden and the
7953 other one is. For backwards compatibility, when both are
7954 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007955 warning later). Also, type.__init__() insists on the same signature
7956 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007957
Georg Brandl3ee81df2008-05-17 18:14:43 +00007958- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7959 object to complex using its __complex__() method before falling back
7960 to the __float__() method. Therefore, the functions in the cmath
7961 module now can operate on objects that define a __complex__()
7962 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007963
Georg Brandl3ee81df2008-05-17 18:14:43 +00007964- Patch #1623563: allow __class__ assignment for classes with
7965 __slots__. The old and the new class are still required to have the
7966 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007967
Georg Brandl3ee81df2008-05-17 18:14:43 +00007968- Patch #1642547: Fix an error/crash when encountering syntax errors
7969 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007971- Patch #1462488: Python no longer segfaults when
7972 ``object.__reduce_ex__()`` is called with an object that is faking
7973 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007974
Georg Brandl3ee81df2008-05-17 18:14:43 +00007975- Patch #1680015: Don't modify __slots__ tuple if it contains an
7976 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00007977
Georg Brandl5240d742007-03-13 20:46:32 +00007978- Patch #1444529: the builtin compile() now accepts keyword arguments.
7979
Georg Brandl7b9c5552007-03-12 14:30:05 +00007980- Bug #1678647: write a newline after printing an exception in any
7981 case, even when converting the value to a string failed.
7982
Georg Brandl871f1bc2007-03-12 13:17:36 +00007983- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007984 its argument, if it exists. If not, it will work like before. This
7985 allows customizing the output of dir() in the presence of a
7986 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007987
Collin Winter276887b2007-03-12 16:11:39 +00007988- Patch #922167: Python no longer segfaults when faced with infinitely
7989 self-recursive reload() calls (as reported by bug #742342).
7990
Georg Brandl3ee81df2008-05-17 18:14:43 +00007991- Patch #1675981: remove unreachable code from ``type.__new__()``
7992 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007994- Patch #1491866: change the complex() constructor to allow
7995 parthensized forms. This means complex(repr(x)) now works instead of
7996 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007997
Georg Brandlaa2321b2007-03-07 00:40:28 +00007998- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007999 makes the filenames the warning module prints much more sensible
8000 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008001
Georg Brandl49aafc92007-03-07 00:34:46 +00008002- Variant of patch #697613: don't exit the interpreter on a SystemExit
8003 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008004 variable is given, but break into the interactive interpreter just
8005 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00008006
Georg Brandl3ee81df2008-05-17 18:14:43 +00008007- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00008010- Bug #1674503: close the file opened by execfile() in an error
8011 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00008012
Georg Brandl0fca97a2007-03-05 22:28:08 +00008013- Patch #1674228: when assigning a slice (old-style), check for the
8014 sq_ass_slice instead of the sq_slice slot.
8015
Georg Brandl3ee81df2008-05-17 18:14:43 +00008016- When printing an unraisable error, don't print exceptions. before
8017 the name. This duplicates the behavior whening normally printing
8018 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00008019
Georg Brandl3ee81df2008-05-17 18:14:43 +00008020- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00008026- Bug #1377858: Fix the segfaulting of the interpreter when an object
8027 created a weakref on itself during a __del__ call for new-style
8028 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00008029
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00008030- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

8075
Armin Rigo7ccbca92006-10-04 12:17:45 +00008076- A number of places, including integer negation and absolute value,
8077 were fixed to not rely on undefined behaviour of the C compiler
8078 anymore.

8081 number of arguments, as was the case in Python 2.4.
8082
Georg Brandl5d59c092006-09-30 08:43:30 +00008083- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00008084 keyword arguments any more (previously they accepted them, but
8085 didn't use them).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008087- Fix a bug in the parser's future statement handling that led to
8088 "with" not being recognized as a keyword after, e.g., this
8089 statement: from __future__ import division, with_statement
Georg Brandla10d3af2006-09-24 12:35:36 +00008090

8098 method. This allows calling unicode() on exceptions classes
8099 directly to succeed.
Brett Cannon9adeab72006-09-20 18:34:28 +00008100
Georg Brandl4e933132006-09-06 20:05:58 +00008101- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

8116 head is the original string if sep was not found.
8117
Neal Norwitzdac090d2006-09-05 03:53:08 +00008118- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008119 generator expressions (x for x, in ... ) works again. Fixing this
8120 problem required changing the .pyc magic number. This means that
8121 .pyc files generated before 2.5c2 will be regenerated.
Neal Norwitzdac090d2006-09-05 03:53:08 +00008122

8627 Python would crash instead of raising an error.

8646 -- the failure just occurred later, with a more cumbersome
8647 exception.

Thomas Hellerd2ea4a22006-10-17 19:30:48 +00008858- ctypes callback functions only support 'fundamental' data types as

8920 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008921
Georg Brandl3ee81df2008-05-17 18:14:43 +00008922- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8923 with RFC 3207 and forgets any knowledge obtained from the server not
8924 obtained from the TLS negotiation itself. Patch contributed by Bill
8925 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008926
Georg Brandl3ee81df2008-05-17 18:14:43 +00008927- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008928 that the SMTP.starttls() caller no longer needs to call ehlo()
8929 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008930 does not claim to support starttls. Adds the
8931 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8932 Fenner.

9012 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9013 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009030 time so that opening a database previously created with the DB_DUP
9031 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9032 opens. Specifically: dictionary assignment to a DB object will
9033 replace all values for a given key when the database allows
9034 duplicate values. DB users should use DB.put(k, v) when they want
9035 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009036

9042 characters with ASCII value less than 32. Also, it correctly quotes
9043 dots only if they occur on a single line, as opposed to the previous
9044 behavior of quoting dots if they are the second character of any
9045 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009046

9377-----
9378
Georg Brandl3ee81df2008-05-17 18:14:43 +00009379- Unified naming convention for free lists and their limits. All free
9380 lists in Object/ are named ``free_list``, the counter ``numfree``
9381 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9382 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009383
Georg Brandl3ee81df2008-05-17 18:14:43 +00009384- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9385 to ``PyTuple_SetItem``, it can be used to populate a brand new
9386 frozenset; but it does not steal a reference to the added item.

9391 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9392 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009393
9394- Patch #1720595: add T_BOOL to the range of structmember types.
9395
9396- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9397 ``PyFloat_GetInfo()`` to the float API.
9398
Georg Brandl3ee81df2008-05-17 18:14:43 +00009399- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9400 of w# format code incorrectly truncated the length to an int, even
9401 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9402 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009403
Georg Brandl3ee81df2008-05-17 18:14:43 +00009404- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9405 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009407- PEP 3123: Provide forward compatibility with Python 3.0, while
9408 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9409 and PyVarObject_HEAD_INIT.

9412 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009413
9414- Patch #1733960: Allow T_LONGLONG to accept ints.

9422- Fix some leftovers from the conversion from int to Py_ssize_t
9423 (relevant to strings and sequences of more than 2**31 items).
9424
9425- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9426 outside of pystate.c and should not be necessary.
9427
Georg Brandl3ee81df2008-05-17 18:14:43 +00009428- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9429 absolute imports. In earlier versions they might have used relative
9430 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009431
Georg Brandl3ee81df2008-05-17 18:14:43 +00009432- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9433 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009434
Georg Brandl3ee81df2008-05-17 18:14:43 +00009435- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009442- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9443 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9444 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9445 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009446

Georg Brandl3ee81df2008-05-17 18:14:43 +00009460- Removed the macfs module. It had been deprecated since Python 2.5.
9461 This lead to the deprecation of macostools.touched() as it relied
9462 solely on macfs and was a no-op under OS X.
