Antoine Pitrou5b4b2da2011-12-15 14:15:31 +0100325- Fix the fix for issue #12149: it was incorrect, although it had the side

Mark Dickinsondbbed042011-09-19 16:38:08 +0100359- Issue #12973: Fix overflow checks that invoked undefined behaviour in
360 int.__pow__. These overflow checks were causing int.__pow__ to produce
361 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100362 compiler optimizing the check away. Also fix similar overflow checks
363 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
364 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +0200375- Issue #12149: Update the method cache after a type's dictionnary gets
376 cleared by the garbage collector. This fixes a segfault when an instance
377 and its type get caught in a reference cycle, and the instance's
378 deallocator calls one of the methods on the type (e.g. when subclassing
379 IOBase). Diagnosis and patch by Davide Rizzo.

389 raw_input() interrupted by CTRL+c.
390
Łukasz Langa7a153902011-10-18 17:16:00 +0200391- Issue #10860: httplib now correctly handles an empty port after port

Florent Xiclunac2279652012-02-12 14:49:03 +0100432- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100433 has left two versions of customize_compiler, the original in
434 distutils.sysconfig and another copy in distutils.ccompiler, with some
435 parts of distutils calling one and others using the other.

437 is the case in 3.x.
438
Ned Deily0d0ea482012-02-10 12:59:06 +0100439- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
440 Distutils-based packages with C extension modules may fail because
441 Apple has removed gcc-4.2, the version used to build python.org
442 64-bit/32-bit Pythons. If the user does not explicitly override
443 the default C compiler by setting the CC environment variable,
444 Distutils will now attempt to compile extension modules with clang
445 if gcc-4.2 is required but not found. Also as a convenience, if
446 the user does explicitly set CC, substitute its value as the default
447 compiler in the Distutils LDSHARED configuration variable for OS X.
448 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
449 SDK, neither of which are available in Xcode 4. This change does not
450 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700723- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
724 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
725 interpreter process. This could cause failures in non-Distutils subprocesses
726 and was unreliable since tests or user programs could modify the interpreter
727 environment after Distutils set it. Instead, have Distutils set the the
728 deployment target only in the environment of each build subprocess. It is
729 still possible to globally override the default by setting
730 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
731 greater or equal to the default value, the value with which the interpreter
732 was built.

Barry Warsawc5643282011-07-19 17:06:30 -0400760- sys.setcheckinterval() now updates the current ticker count as well as
761 updating the check interval, so if the user decreases the check interval,
762 the ticker doesn't have to wind down to zero from the old starting point
763 before the new interval takes effect. And if the user increases the
764 interval, it makes sure the new limit takes effect right away rather have an
765 early task switch before recognizing the new interval.

1714 This prevents user-created self-referencing ordered dictionaries from
1715 becoming permanently uncollectable GC garbage. The downside is that
1716 removing __del__ means that the internal doubly-linked list has to wait for
1717 GC collection rather than freeing memory immediately when the refcnt drops
1718 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002177- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2178 start byte and the continuation byte(s) are now considered invalid, instead
2179 of the number of bytes specified by the start byte.
2180 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2181 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2182 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002191- Issue #8748: Fix two issues with comparisons between complex and integer
2192 objects. (1) The comparison could incorrectly return True in some cases
2193 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2194 (2) The comparison raised an OverflowError for large integers, leading
2195 to unpredictable exceptions when combining integers and complex objects
2196 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00002198- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00002335- Issue #1533: Fix inconsistency in range function argument processing: any
2336 non-float non-integer argument is now converted to an integer (if possible)
2337 using its __int__ method. Previously, only small arguments were treated this
2338 way; larger arguments (those whose __int__ was outside the range of a C long)
2339 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00002347 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00002348 benefit compared to the dynamic memory allocation fallback. Patch by

2374 messages when accessing undefined class attributes because of the cheap
2375 inheritance with the underlying socket object. The cheap inheritance has been
2376 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00002389- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2390 operation raises multiple signals and more than one of those signals is
2391 trapped, the specification determines the order in which the signals should be
2392 handled. In many cases this order wasn't being followed, leading to the wrong
2393 Python exception being raised.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002563- Issue #7301: Add environment variable $PYTHONWARNINGS.
2564
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002565- Issue #8329: Don't return the same lists from select.select when no fds are
2566 changed.
2567
Georg Brandlfee0f442010-05-22 21:26:21 +00002568- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002569 on 64-bit machines. The shift count for either left or right shift is
2570 permitted to be up to sys.maxsize.
2571
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002572- Ensure that tokenization of identifiers is not affected by locale.
2573
Georg Brandlfee0f442010-05-22 21:26:21 +00002574- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002575
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002576- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2577
Georg Brandlfee0f442010-05-22 21:26:21 +00002578- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2579 with a non-empty format string. This is an effort to future-proof user
2580 code. If a derived class does not currently implement __format__ but later
2581 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002582 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002583 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002584
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002585- Issue #8268: Old-style classes (not just instances) now support weak
2586 references.
2587
Georg Brandlfee0f442010-05-22 21:26:21 +00002588- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2589 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00002590

2597
Victor Stinner66644262010-03-10 22:30:19 +00002598- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002599 (SIGINT). If an error occurs while importing the site module, the error is
2600 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002601 module.

2609
Antoine Pitrouf9de5342010-04-05 21:35:07 +00002610- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002611 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2612 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002614- Issue #8310: Allow dis to examine new style classes.
2615
Georg Brandlfee0f442010-05-22 21:26:21 +00002616- Issue #8257: The Decimal construct now accepts a float instance directly,
2617 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002618
2619 >>> Decimal(1.1)
2620 Decimal('1.100000000000000088817841970012523233890533447265625')
2621
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002622- collections.Counter() now supports a subtract() method.
2623
Georg Brandlfee0f442010-05-22 21:26:21 +00002624- The functools module now has a total_ordering() class decorator to simplify
2625 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002626
Georg Brandlfee0f442010-05-22 21:26:21 +00002627- The functools module also adds cmp_to_key() as a tool to transition old-style
2628 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002629
Georg Brandlfee0f442010-05-22 21:26:21 +00002630- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2631 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002632
Georg Brandlfee0f442010-05-22 21:26:21 +00002633- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2634 InvalidOperation instead of returning False. (Comparisons involving a quiet
2635 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2636 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002637
Georg Brandlfee0f442010-05-22 21:26:21 +00002638- Issue #2531: Comparison operations between floats and Decimal instances now
2639 return a result based on the numeric values of the operands; previously they
2640 returned an arbitrary result based on the relative ordering of id(float) and
2641 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002642
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002643- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002644 argument `-` which tells it to read files to compile from stdin. Each line is
2645 read on demand and the named file is compiled immediately. (Original patch by
2646 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002647
Georg Brandlfee0f442010-05-22 21:26:21 +00002648- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2649 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002651- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2652 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002653 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002654
Georg Brandlfee0f442010-05-22 21:26:21 +00002655- Comparisons using one of <, <=, >, >= between a complex instance and a
2656 Fractions instance now raise TypeError instead of returning True/False. This
2657 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2658 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002659

2668
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002669- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002670 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2671 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002672
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002673- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2674 deprecated.
2675
Georg Brandlfee0f442010-05-22 21:26:21 +00002676- Issue #7860: platform.uname now reports the correct 'machine' type when Python
2677 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00002678

Vinay Sajipecfa08f2010-03-12 09:16:10 +00002713- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00002714 for ``TimedRotatingFileHandler`` by using the modification time of an existing
2715 log file to compute the next rollover time. If the log file does not exist,
2716 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00002717

Georg Brandlba83f822010-03-14 09:50:54 +00002726- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
2727 a base64 transfer-encoded payload *after* decoding it; it no longer does.
2728 This is a behavior change, so email's minor version number is now bumped, to
2729 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00002757- Issue #8300: When passing a non-integer argument to struct.pack with any
2758 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00002762- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
2763 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2764 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002765 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2766 inconsistent: __int__ was used for some integer codes but not for others, and
2767 the set of integer codes for which it was used differed between native packing
2768 and standard packing.)

3172Core and Builtins
3173-----------------
3174
Georg Brandlba83f822010-03-14 09:50:54 +00003175- The ``__complex__()`` method is now looked up on the class of instances to
3176 make it consistent with other special methods.

3180
Mark Dickinson1b34d252010-01-01 17:27:30 +00003181- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003182 DeprecationWarning when passed a float argument where an integer was expected.
3183 These functions and methods now raise TypeError instead. The majority of the
3184 effects of this change are in the extension modules, but some core functions
3185 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3186 and many unicode/str methods.

3200 of integers: the result of a/b is now correctly rounded for ints a and b (at
3201 least on IEEE 754 platforms), and in particular does not depend on the
3202 internal representation of a long.

3210
Georg Brandlba83f822010-03-14 09:50:54 +00003211 These executables now work properly with the arch(1) command: ``arch -ppc
3212 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003369- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3370 decimal string that's guaranteed to round back to x under correct rounding
3371 (with round-half-to-even rounding mode). Previously it gave a string based on
3372 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3373 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3374 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003375
Georg Brandlba83f822010-03-14 09:50:54 +00003376- Issue #7117: On almost all platforms: float-to-string and string-to-float
3377 conversions within Python are now correctly rounded. Places these conversions
3378 occur include: str for floats and complex numbers; the float and complex
3379 constructors; old-style and new-style numeric formatting; serialization and
3380 deserialization of floats and complex numbers using marshal, pickle and json;
3381 parsing of float and imaginary literals in Python code; Decimal-to-float
3382 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003383
Georg Brandlba83f822010-03-14 09:50:54 +00003384 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3385 providing correctly-rounded strtod and dtoa C functions. This code is
3386 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3387 the C compiler. There may be a small number of platforms on which correct
3388 operation of this code cannot be guaranteed, so the code is not used: notably,
3389 this applies to platforms where the C double format is not IEEE 754 binary64,
3390 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3391 and Python's configure script is unable to determine how to change the FPU
3392 precision. On these platforms conversions use the platform strtod and dtoa,
3393 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003395- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3396 uses the correctly-rounded string <-> float conversions described above (when
3397 available), and so produces correctly rounded results that will display nicely
3398 under the float repr. There are two related small changes: (1) round now
3399 accepts any class with an ``__index__()`` method for its second argument (but
3400 no longer accepts floats for the second argument), and (2) an excessively
3401 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3402 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003544
Georg Brandlba83f822010-03-14 09:50:54 +00003545 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3546 (2) parsing of strings representing infinities and nans was locale aware; and
3547 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00003548
Georg Brandlba83f822010-03-14 09:50:54 +00003549- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3550 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3551 but with at least one decimal point and with a default precision
3552 of 12. Previously, the behavior the same but with a default precision of 6.
3553 This more closely matches ``str()``, and reduces surprises when adding
3554 alignment flags to the empty presentation type. This also affects the new
3555 complex.__format__ in the same way.
3556
3557- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3558 classtype's, even if it was None. property now inserts the __doc__ into the
3559 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00003620 untrackable objects are not tracked by the garbage collector. This can reduce
3621 the size of collections and therefore the garbage collection overhead on

3629 internal representation of integers, for performance reasons. Base 2**30 is
3630 enabled by default on 64-bit machines. Add --enable-big-digits option to
3631 configure, which overrides the default. Add sys.long_info structseq to
3632 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00003733- Issue #4597: Fixed exception handling when the __exit__ function of a context
3734 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00003735
Georg Brandlba83f822010-03-14 09:50:54 +00003736- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00003737
Georg Brandlba83f822010-03-14 09:50:54 +00003738- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3739 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3740 instances. On a typical machine this saves 3 bytes of memory (on average) per
3741 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00003742
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003743- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3744 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3745 instead of throwing a MemoryError.
3746
Georg Brandlba83f822010-03-14 09:50:54 +00003747- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3748 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00003749
Benjamin Petersonc078f922008-11-21 22:27:24 +00003750- Issue #4367: Python would segfault during compiling when the unicodedata
3751 module couldn't be imported and \N escapes were present.
3752
Georg Brandlba83f822010-03-14 09:50:54 +00003753- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3754 file objects with closefd=False. The file descriptor is still kept open but
3755 the file object behaves like a closed file. The ``FileIO`` object also got a
3756 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00003757
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003758- Issue #4348: Some bytearray methods returned that didn't cause any change to
3759 the bytearray, returned the same bytearray instead of a copy.
3760
Georg Brandlba83f822010-03-14 09:50:54 +00003761- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00003762
Benjamin Peterson273c2332008-11-17 22:39:09 +00003763- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
3764
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00003765- Issue #4048: The parser module now correctly validates relative imports.
3766
Benjamin Petersondcee09d2008-10-31 02:16:05 +00003767- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
3768 exec statement.
3769
Georg Brandlba83f822010-03-14 09:50:54 +00003770- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
3771 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00003772
Benjamin Petersonbdca9422008-10-26 20:21:13 +00003773- Issue #4209: Enabling unicode_literals and the print_function in the same
3774 __future__ import didn't work.
3775
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003776- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003777 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003778
Georg Brandlba83f822010-03-14 09:50:54 +00003779- On windows, ``os.chdir()`` given unicode was not working if
3780 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3781 this code path is really executed because I cannot move to such directory on
3782 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003783
Georg Brandlba83f822010-03-14 09:50:54 +00003784- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3785 element is temporarily replaced with an equivalent frozenset. But the
3786 eventual KeyError would always report the empty ``frozenset()`` as the missing
3787 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00003788
Georg Brandlba83f822010-03-14 09:50:54 +00003789- Issue #4509: Various issues surrounding resize of bytearray objects to which
3790 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00003791
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00003792- Issue #4748: Lambda generators no longer return a value.
3793
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00003794- Issue #3582: Use native TLS functions on Windows
3795
Gregory P. Smithae91d092009-03-02 05:13:57 +00003796- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
3797
Georg Brandlba83f822010-03-14 09:50:54 +00003798- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
3799 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00003800
Matthias Klose91a3b9e2009-04-05 21:19:13 +00003801- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
3802 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00003803
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00003804- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
3805 returned them on 64bit platforms.
3806
Walter Dörwalded960ac2009-05-03 22:36:33 +00003807- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3808 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3809 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3810 of using the replace error handler in PyUnicode_DecodeUTF8().
3811
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003812- Issue #3739: The unicode-internal encoder now reports the number of characters
3813 consumed like any other encoder (instead of the number of bytes).
3814
Georg Brandlba83f822010-03-14 09:50:54 +00003815- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3816 allocator will be automatically disabled when running under Valgrind. This
3817 gives improved memory leak detection when running under Valgrind, while taking
3818 advantage of pymalloc at other times.

3837 msvc9compiler.
3838
Georg Brandlba83f822010-03-14 09:50:54 +00003839- Issue #7333: The ``posix`` module gains an ``initgroups()`` function providing

3841 Patch by Jean-Paul Calderone.
Antoine Pitrou30b3b352009-12-02 20:37:54 +00003842
Tarek Ziadéa5076a22009-11-29 22:20:30 +00003843- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
3844 ownership when the group is not forced, because the group may be different
3845 from the user's group and inherit from its container when the test is run.
3846
Georg Brandlba83f822010-03-14 09:50:54 +00003847- Issue #1515: Enable use of deepcopy() with instance methods. Patch by Robert

Georg Brandlba83f822010-03-14 09:50:54 +00003887- Issue #6816: runpy now provides a run_path function that allows Python code to
3888 execute file paths that refer to source or compiled Python files as well as
3889 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00003890 __main__.py file. This allows applications that run other Python scripts to
3891 support the same flexibility as the CPython command line itself.
3892
Georg Brandlba83f822010-03-14 09:50:54 +00003893- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
3894 connection with another process, rather than looping endlessly. The default
3895 timeout is 20 seconds, which should be amply sufficient for local connections.

Antoine Pitrouaec41242009-11-02 11:34:27 +00003912 a modification is done through it. This fixes inconsistencies and test

3916 from stdin so that existing input does not confuse it and lead to incorrect
3917 entry or an IOError. It also properly flushes it afterwards to avoid the
3918 terminal echoing the input afterwards on OSes such as Solaris.

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00005164 AttributeError instead of RuntimeError, depending in which C API call

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005183- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5184
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005185- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5186 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5187 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5188 ``printf`` function, whereas PyString_FromFormat has an independent
5189 implementation and uses "%zd" on all platforms for size_t values.
5190 This makes a difference on win64, where ``printf`` needs "%Id" to display
5191 64bit values.
5192
Benjamin Peterson97179b02008-09-09 20:55:01 +00005193- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5194 error.

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005196- Issue #3777: long() applied to a float object now always return a long
5197 object; previously an int would be returned for small values. the __long__
5198 method is allowed to return either an int or a long, but the behaviour of
5199 float objects should not change to respect backward compatibility.
5200
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005201- Issue #3751: str.rpartition would perform a left-partition when called with
5202 a unicode argument.
5203
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005204- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005207 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005208 was correctly parsed but parsing of subsequent arguments failed.
5209
Vinay Sajip35e3b032008-09-01 14:33:59 +00005210- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005211 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5212 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5213 when given a tuple of classes as second argument, were looking up
5214 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5215 type object.
5216
Neal Norwitz18aa3882008-08-24 05:04:52 +00005217- Fix crashes on memory allocation failure found with failmalloc.
5218
5219- Fix memory leaks found with valgrind and update suppressions file.
5220
5221- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5222
5223- Fix problem using wrong name in decimal module reported by pychecker.

Brett Cannon672237d2008-09-09 00:49:16 +00005260 return a list or None rather than a custom object.
5261
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005262- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005286 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5287 for catch_warnings() also led to an improvement in the raising of a

5360-----------------
5361
Guido van Rossumf8402962008-08-20 15:01:50 +00005362- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5363 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5364 extensions do not automatically benefit from the class attribute
5365 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5366 to their tp_flags field if they care. This is a backwards
5367 compatibility feature; in 3.0, all types will use the cache by
5368 default.
5369
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005370- Keyword arguments can now follow starred arguments. (``f(a, *args,
5371 keyword=23)`` is now valid syntax.)
5372
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005373- ctypes function pointers that are COM methods have a boolean True
5374 value again.
5375
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005376- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5377 by denying s# to parse objects that have a releasebuffer procedure,
5378 and introducing s*.
5379
Georg Brandl1e13ea92008-08-11 09:07:59 +00005380- Issue #3537: Fix an assertion failure when an empty but presized dict
5381 object was stored in the freelist.
5382
Mark Dickinsonb6467572008-08-04 21:30:09 +00005383- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5384 ValueError consistently across platforms.
5385
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005386- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5387 (64bit Unix, for example), unichr() would truncate its argument and return
5388 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5389
Neal Norwitze7d8be82008-07-31 17:17:14 +00005390- Apply security patches from Apple.
5391
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005392- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00005395- Issue #1819: function calls with several named parameters are now on
5396 average 35% faster (as measured by pybench).
5397
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005398- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5399 the python debugger steps into a class statement: the free variables (local
5400 variables defined in an outer scope) would be deleted from the outer scope.
5401
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005402- Issue #2620: Overflow checking when allocating or reallocating memory
5403 was not always being done properly in some python types and extension
5404 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5405 all been updated to perform better checks and places in the code that
5406 would previously leak memory on the error path when such an allocation
5407 failed have been fixed.

5413
Benjamin Petersone977ad42008-08-20 01:42:01 +00005414- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5415 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5416
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005417- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5418 version reported by these tools does not necessarily follow the python
5419 version numbering scheme, so the module is less strict when parsing it.
5420
Nick Coghlanf70385a2008-08-18 12:42:46 +00005421- Issue #2235: Added Py3k warnings for types which will become unhashable
5422 under the stricter __hash__ inheritance rules in 3.0. Several types
5423 which did not meet the rules for hash invariants and were already
5424 unhashable in 3.0 have now been explicitly flagged as unhashable in
5425 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5426 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5427
Brett Cannon88f801d2008-08-18 00:46:22 +00005428- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5429 imported into the module but exposed as part of the module's API.
5430

5450 after a 302 response in the case of not going through a proxy.
5451
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005452- Issue #2676: in the email package, content-type parsing was hanging on
5453 pathological input because of quadratic or exponential behaviour of a
5454 regular expression.
5455
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005456- Issue #3476: binary buffered reading through the new "io" library is now
5457 thread-safe.
5458
Brett Cannonbf3157b2008-08-14 05:00:03 +00005459- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5460 since mimetools itself is deprecated. Because modules are cached, all
5461 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5462
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005463- Issue #3134: shutil referenced undefined WindowsError symbol.

5466 menu entries were not deleted.
5467
Brett Cannon83e81842008-08-09 23:30:55 +00005468- Copied the implementation of reduce() to _functools.reduce() to have a

5470
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005471- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5472 a MemoryError rather than silently stop the iteration.
5473
Guido van Rossum59ce9012008-08-09 14:55:34 +00005474- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5475 to _sre.compile() will now be rejected. This should not affect anybody
5476 since the re.compile() function never generates invalid re-bytecode.
5477
Skip Montanaroa032bf42008-08-08 22:52:51 +00005478- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5479 upon first access it can be automatically initialized from the csv file if
5480 it wasn't initialized during instantiation.
5481
Brett Cannon3aa2a492008-08-06 22:28:09 +00005482- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5483 the reload() built-in has been removed.
5484
Brett Cannon7e30b672008-08-04 21:52:25 +00005485- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005486 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5494 raised an AttributeError.
5495
Benjamin Peterson01a24322008-07-28 23:35:27 +00005496- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005497 asking for a specific length. This problem only affected files opened
5498 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005499

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005523- Issue #3394: zipfile.writestr sets external attributes when passed a
5524 file name rather than a ZipInfo instance, so files are extracted with
5525 mode 0600 rather than 000 under Unix.
5526
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005527- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5528 argument in python 2.5, this broke code that subclassed Popen to include its
5529 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005539- Issue #2235: the C API function PyObject_HashNotImplemented and its
5540 interaction with the tp_hash slot (added in 2.6b2) are now documented
5541
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005542- Issue #643841: The language reference now provides more detailed
5543 coverage of the lookup process for special methods. The disclaimers
5544 regarding lack of coverage of new-style classes have also been
5545 removed, since the coverage is now fairly reasonable.

5549================================
5550
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005551*Release date: 17-Jul-2008*
5552
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005553Core and Builtins
5554-----------------
5555
Georg Brandl3e483f62008-07-16 22:57:41 +00005556- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5557 its methods now allow for items objects that can be converted to
5558 an integer using operator.index().
5559
Mark Dickinson64b7e502008-07-16 09:40:03 +00005560- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5561 produced a ValueError instead of giving the correct float.
5562
Eric Smitha5fa5a22008-07-16 00:11:49 +00005563- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5564 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5565
Mark Dickinson7103aa42008-07-15 19:08:33 +00005566- Issue #3008: the float type has a new instance method 'float.hex'
5567 and a new class method 'float.fromhex' to convert floating-point
5568 numbers to and from hexadecimal strings, respectively.
5569
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005570- Issue #2235: __hash__ is once again inherited by default. To allow
5571 collections.Hashable to remain meaningful in the presence of the
5572 default hash implementation (object.__hash__), it is now possible
5573 to explicit block inheritance of hash by setting __hash__=None at
5574 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5575 level.
5576
Nick Coghlanb028f502008-07-13 14:52:36 +00005577- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5578 the parent module cannot be found while performing an absolute import.
5579 This means that an incorrectly defined __package__ attribute will
5580 now only prevent relative imports in that module rather than causing
5581 all imports from that module to fail.
5582
Nick Coghlan14ff9942008-07-08 14:21:42 +00005583- Issue #2517: Allow unicode messages in Exceptions again by correctly
5584 bypassing the instance dictionary when looking up __unicode__ on
5585 new-style classes.
5586
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005587- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5588 set to a custom object whose write() method happens to install
5589 another file in sys.stdout.
5590
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005591- Issue #3088: Corrected a race condition in classes derived from
5592 threading.local: the first member set by a thread could be saved in
5593 another thread's dictionary.
5594
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005595- Issue #3004: Minor change to slice.indices(): the start and stop
5596 arguments are now treated identically, making the behaviour easier
5597 to describe and understand. For example, slice(None, -10,
5598 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5599 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5600 10, -1).
5601
Georg Brandl278fc502008-07-19 12:46:12 +00005602- Issue #3219: Calling a function with repeated keyword arguments,
5603 f(a=2, a=23), would not cause a syntax error. This was a regression
5604 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005605
Georg Brandl278fc502008-07-19 12:46:12 +00005606- Issue #2862: Make int and float freelist management consistent with
5607 other freelists. Changes their CompactFreeList apis into
5608 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005609

5612
Thomas Heller57adf222008-08-14 19:10:48 +00005613- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5614 api functions without holding the GIL, which could lead to a fatal
5615 error when they failed.
5616
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005617- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00005625- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5626 ForkingPickler.register() to resolve conflict with ctypes.
5627
Vinay Sajip51e65192008-07-18 09:01:10 +00005628- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005629
Thomas Heller880f5292008-07-15 19:39:38 +00005630- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5631 a valid dlerror() message.
5632
Thomas Heller2bad6572008-07-15 17:19:50 +00005633- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5634 incomplete structure was created.
5635

5639
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005640- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005641
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005642- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5643 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005644 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005645 content-length. The problem had been corrected in the 2.4 branch, but never
5646 merged into trunk.
5647
Georg Brandle78fbcc2008-07-05 10:13:36 +00005648- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005659 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005660
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005661- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5662 handling is now the same as that of other special attributes like __name__).
5663
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005664- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5665 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00006054 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006055
6056 This is controlled by the configure argument ``--with-universal-archs``:
6057
6058 - ``--with-universal-archs=all``: install 4-way universal
6059
6060 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6061
6062 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6063
6064 This option should be used in combination with ``--enable-universalsdk=``.
6065
6066 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 +00006116- Issue #1631171: Re-implement the 'warnings' module in C (the
6117 original Python code has been kept as backup). This will allow for
6118 using the 'warning's machinery in such places as the parser where
6119 use of pure Python code is not possible. Both the ``showarning()``
6120 and ``formatwarning()`` gain an optional 'line' argument which is
6121 not called by default for backwards-compatibility reasons. Setting
6122 ``warnings.showwarning()`` to an implementation that lacks support
6123 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006186- Issue #2550: The approach used by client/server code for obtaining
6187 ports to listen on in network-oriented tests has been refined in an
6188 effort to facilitate running multiple instances of the entire
6189 regression test suite in parallel without issue.
6190 test_support.bind_port() has been fixed such that it will always
6191 return a unique port -- which wasn't always the case with the
6192 previous implementation, especially if socket options had been set
6193 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6194 new implementation of bind_port() will actually raise an exception
6195 if it is passed an AF_INET/SOCK_STREAM socket with either the
6196 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6197 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6198 the socket it's been passed. This currently only applies to
6199 Windows. This option prevents any other sockets from binding to the
6200 host/port we've bound to, thus removing the possibility of the
6201 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6202 when a second SOCK_STREAM socket binds and accepts to a host/port
6203 that's already been bound by another socket. The optional preferred
6204 port parameter to bind_port() has been removed. Under no
6205 circumstances should tests be hard coding ports!
6206
6207 test_support.find_unused_port() has also been introduced, which will
6208 pass a temporary socket object to bind_port() in order to obtain an
6209 unused port. The temporary socket object is then closed and
6210 deleted, and the port is returned. This method should only be used
6211 for obtaining an unused port in order to pass to an external program
6212 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6213 a parameter to a server-oriented class that doesn't give you direct
6214 access to the underlying socket used.
6215
6216 Finally, test_support.HOST has been introduced, which should be used
6217 for the host argument of any relevant socket calls (i.e. bind and
6218 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006219
6220 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006221 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

6223 test_asynchat and test_socket_ssl.
6224
Georg Brandl3ee81df2008-05-17 18:14:43 +00006225 It is now possible for multiple instances of the regression test
6226 suite to run in parallel without issue.

6493-----------------
6494
Fred Drakea8ee94b2008-03-01 02:45:07 +00006495- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006496 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006497
Georg Brandlad61bc82008-02-23 15:11:18 +00006498- Issue #2067: file.__exit__() now calls subclasses' close() method.
6499
6500- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006501
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006502- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006503 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006504
Eric Smitha73fbe72008-02-23 03:09:44 +00006505- Added the future_builtins module, which contains hex() and oct().
6506 These are the PEP 3127 version of these functions, designed to be
6507 compatible with the hex() and oct() builtins from Python 3.0. They
6508 differ slightly in their output formats from the existing, unchanged
6509 Python 2.6 builtins. The expected usage of the future_builtins
6510 module is:
6511 from future_builtins import hex, oct
6512
Eric Smith7ef40bf2008-02-20 23:34:22 +00006513- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6514 exponents for exponents with absolute value < 100. Follows C99
6515 standard. This is a change on Windows, which would use 3 digits.
6516 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6517 so that any alterations it does to the resulting string will be
6518 available in stringlib/formatter.h (for float.__format__).
6519
Eric Smith5a3c1352008-02-19 13:21:56 +00006520- Implemented PEP 3101, Advanced String Formatting. This adds a new
6521 builtin format(); a format() method for str and unicode; a
6522 __format__() method to object, str, unicode, int, long, float, and
6523 datetime; the class string.Formatter; and the C API
6524 PyObject_Format().
6525
Georg Brandl3ee81df2008-05-17 18:14:43 +00006526- Fixed several potential crashes, all caused by specially crafted
6527 __del__ methods exploiting objects in temporarily inconsistent
6528 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006529
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006530- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006531 prevent a possible crash: an Abstract Base Class would try to access
6532 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006533
Georg Brandl3ee81df2008-05-17 18:14:43 +00006534- Fixed repr() and str() of complex numbers with infinity or nan as
6535 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006536
Georg Brandl3ee81df2008-05-17 18:14:43 +00006537- Clear all free lists during a gc.collect() of the highest generation
6538 in order to allow pymalloc to free more arenas. Python may give back
6539 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006540
Georg Brandl3ee81df2008-05-17 18:14:43 +00006541- Issue #2045: Fix an infinite recursion triggered when printing a
6542 subclass of collections.defaultdict, if its default_factory is set
6543 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006544
Christian Heimesf75dbef2008-02-08 00:11:31 +00006545- Fixed a minor memory leak in dictobject.c. The content of the free
6546 list was not freed on interpreter shutdown.
6547
Georg Brandl21e99f42010-03-07 15:23:59 +00006548- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006549 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006550
Georg Brandl3ee81df2008-05-17 18:14:43 +00006551- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6552 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006553 to compact the internal free lists of pre-allocted ints and floats.
6554
Georg Brandl3ee81df2008-05-17 18:14:43 +00006555- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6556 calls. Python expected the return type int but the fork familie
6557 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006558
Georg Brandl3ee81df2008-05-17 18:14:43 +00006559- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6560 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006561
Georg Brandl3ee81df2008-05-17 18:14:43 +00006562- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6563 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006564
Georg Brandl3ee81df2008-05-17 18:14:43 +00006565- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6566 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006567
Georg Brandl3ee81df2008-05-17 18:14:43 +00006568- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6569 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006570
Georg Brandl3ee81df2008-05-17 18:14:43 +00006571- Patch #1473257: generator objects gain a gi_code attribute. This is
6572 the same object as the func_code attribute of the function that
6573 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006574
Georg Brandl3ee81df2008-05-17 18:14:43 +00006575- Issue #1920: "while 0" statements were completely removed by the
6576 compiler, even in the presence of an "else" clause, which is
6577 supposed to be run when the condition is false. Now the compiler
6578 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006579
Guido van Rossumeead05f2008-01-24 18:21:02 +00006580- A few crashers fixed: weakref_in_del.py (issue #1377858);
6581 loosing_dict_ref.py (issue #1303614, test67.py);
6582 borrowed_ref_[34].py (not in tracker).
6583
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006584- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006585 suppressed while an extension is loaded by calling SetErrorMode in
6586 dynload_win.c. The error is still reported properly.
6587
Georg Brandl3ee81df2008-05-17 18:14:43 +00006588- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006589 several extension methods and modules do not work without unicode
6590 support.
6591
Georg Brandl26543b12008-01-21 18:36:51 +00006592- Issue #1882: when compiling code from a string, encoding cookies in the
6593 second line of code were not always recognized correctly.
6594
Georg Brandl14404b62008-01-19 19:27:05 +00006595- Issue #1679: "0x" was taken as a valid integer literal.
6596
Georg Brandl6caad7d2008-01-26 14:19:22 +00006597- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006598 added.
6599
Christian Heimesc94e2b52008-01-14 04:13:37 +00006600- sys.float_info / PyFloat_GetInfo: The floating point information
6601 object was converted from a dict to a specialized structseq object.
6602
Georg Brandl3ee81df2008-05-17 18:14:43 +00006603- Patch #1816: Added sys.flags structseq. It exposes the status of
6604 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006605
Georg Brandl3ee81df2008-05-17 18:14:43 +00006606- Objects/structseq.c: Implemented new structseq representation. The
6607 patch makes structseqs (e.g. the return value of os.stat) more
6608 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006609
Georg Brandl3ee81df2008-05-17 18:14:43 +00006610- Patch #1700288: added a type attribute cache that caches method
6611 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006612
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006613- Bug #1776: __import__() no longer accepts filenames on any platform.
6614 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006615
Georg Brandlaed6c662008-01-07 17:25:53 +00006616- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6617
Georg Brandl3ee81df2008-05-17 18:14:43 +00006618- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6619 envvar and sys.dont_write_bytecode attribute. All these can be set
6620 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006621
Georg Brandl3ee81df2008-05-17 18:14:43 +00006622- Improve some exception messages when Windows fails to load an
6623 extension module. Now we get for example '%1 is not a valid Win32
6624 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006625
Georg Brandl3ee81df2008-05-17 18:14:43 +00006626- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006628- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6629 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006630
Christian Heimes0a8143f2007-12-18 23:22:54 +00006631- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006632 and INF. float("nan"), float("inf") and float("-inf") now work on
6633 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006634
Georg Brandl3ee81df2008-05-17 18:14:43 +00006635- Compiler now generates simpler and faster code for dictionary
6636 literals. The oparg for BUILD_MAP now indicates an estimated
6637 dictionary size. There is a new opcode, STORE_MAP, for adding
6638 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006639
Georg Brandl3ee81df2008-05-17 18:14:43 +00006640- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006645- Issue #1538: Avoid copying string in split/rsplit if the split char
6646 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006647
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006648- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006649 SystemError.
6650
Nick Coghlanef01d822007-12-03 12:55:17 +00006651- PEP 366: Allow explicit relative imports when executing modules

6653 __package__ attribute.
6654
Georg Brandl3ee81df2008-05-17 18:14:43 +00006655- Issue #1402: Fix a crash on exit, when another thread is still
6656 running, and if the deallocation of its frames somehow calls the
6657 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006658

6668 file can now be directly executed by passing their name to the
6669 interpreter. The directory/zipfile is automatically inserted as the
6670 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006671
Georg Brandl3ee81df2008-05-17 18:14:43 +00006672- Issue #1265: Fix a problem with sys.settrace, if the tracing
6673 function uses a generator expression when at the same time the
6674 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006675
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006676- sets and frozensets now have an isdisjoint() method.
6677
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006678- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00006680- Fix warnings found by the new version of the Coverity checker.
6681
Georg Brandl21e99f42010-03-07 15:23:59 +00006682- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006683 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6684 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006685
Georg Brandl3ee81df2008-05-17 18:14:43 +00006686- Issue #1686386: Tuple's tp_repr did not take into account the
6687 possibility of having a self-referential tuple, which is possible
6688 from C code. Nor did object's tp_str consider that a type's tp_str
6689 could do something that could lead to an inifinite recursion.
6690 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6691 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006692
Georg Brandl3ee81df2008-05-17 18:14:43 +00006693- Issue #1164: It was possible to trigger deadlock when using the
6694 'print' statement to write to a file since the GIL was not released
6695 as needed. Now PyObject_Print() does the right thing along with
6696 various tp_print implementations of the built-in types and those in
6697 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006698
Georg Brandl3ee81df2008-05-17 18:14:43 +00006699- Issue #1147: Exceptions were directly allowing string exceptions in
6700 their throw() method even though string exceptions no longer
6701 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006702

Brett Cannon1e534b52007-09-07 04:18:30 +00006706- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006707 PyObject_Call() never calling back out to Python code to trigger
6708 recursion depth updates/checks. Required the creation of a static
6709 RuntimeError instance in case normalizing an exception put the
6710 recursion check value past its limit. Fixes crashers
6711 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006712

Neal Norwitz0ac60192007-05-27 04:08:54 +00006726- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006727 __*__ attributes. (Some already existed, e.g., __doc__ and
6728 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006729
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006730- Add -3 option to the interpreter to warn about features that are

6734 calls.
6735
Collin Winter62903052007-05-18 23:11:24 +00006736- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006737 "except E as target:". This is to provide forwards compatibility
6738 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006739
Brett Cannon229cee22007-05-05 01:34:02 +00006740- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006745- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006746 setting a plain string, ie don't expand to single letter identifiers.
6747
Raymond Hettinger13936692007-04-11 18:40:58 +00006748- Request #1191699: Slices can now be pickled.

6758
Guido van Rossum143b5642007-03-23 04:58:42 +00006759- Bug #1683368: The object.__init__() and object.__new__() methods are
6760 now stricter in rejecting excess arguments. The only time when
6761 either allows excess arguments is when it is not overridden and the
6762 other one is. For backwards compatibility, when both are
6763 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006764 warning later). Also, type.__init__() insists on the same signature
6765 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006766
Georg Brandl3ee81df2008-05-17 18:14:43 +00006767- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6768 object to complex using its __complex__() method before falling back
6769 to the __float__() method. Therefore, the functions in the cmath
6770 module now can operate on objects that define a __complex__()
6771 method.

6788
Georg Brandl7b9c5552007-03-12 14:30:05 +00006789- Bug #1678647: write a newline after printing an exception in any
6790 case, even when converting the value to a string failed.
6791
Georg Brandl871f1bc2007-03-12 13:17:36 +00006792- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006793 its argument, if it exists. If not, it will work like before. This
6794 allows customizing the output of dir() in the presence of a
6795 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006796
Collin Winter276887b2007-03-12 16:11:39 +00006797- Patch #922167: Python no longer segfaults when faced with infinitely
6798 self-recursive reload() calls (as reported by bug #742342).
6799

6804 parthensized forms. This means complex(repr(x)) now works instead of
6805 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006806
Georg Brandlaa2321b2007-03-07 00:40:28 +00006807- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006808 makes the filenames the warning module prints much more sensible
6809 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006810

Georg Brandl0fca97a2007-03-05 22:28:08 +00006822- Patch #1674228: when assigning a slice (old-style), check for the
6823 sq_ass_slice instead of the sq_slice slot.
6824
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825- When printing an unraisable error, don't print exceptions. before
6826 the name. This duplicates the behavior whening normally printing
6827 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007360 AttributeError instead of an IOError when the server's response
7361 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007367- Patch #1429539: pdb now correctly initializes the __main__ module
7368 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007369 correctly now.
7370

7393
Georg Brandl92a6bae2007-03-13 17:43:32 +00007394- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007395 are set for invalid interpolation sequences that would lead to
7396 errors on reading back those values.

7450

7452 TestCase and TestSuite subclasses (not instances) are no longer
7453 accepted in TestSuite.addTest(). This should cause no
7454 incompatibility since it never made sense with ordinary subclasses
7455 -- the failure just occurred later, with a more cumbersome

Georg Brandl3ee81df2008-05-17 18:14:43 +00007737- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7738 with RFC 3207 and forgets any knowledge obtained from the server not
7739 obtained from the TLS negotiation itself. Patch contributed by Bill
7740 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007741
Georg Brandl3ee81df2008-05-17 18:14:43 +00007742- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007743 that the SMTP.starttls() caller no longer needs to call ehlo()
7744 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007745 does not claim to support starttls. Adds the
7746 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

7827 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7828 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007845 time so that opening a database previously created with the DB_DUP
7846 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7847 opens. Specifically: dictionary assignment to a DB object will
7848 replace all values for a given key when the database allows
7849 duplicate values. DB users should use DB.put(k, v) when they want
7850 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007851

7857 characters with ASCII value less than 32. Also, it correctly quotes
7858 dots only if they occur on a single line, as opposed to the previous
7859 behavior of quoting dots if they are the second character of any
7860 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007861

Georg Brandl3ee81df2008-05-17 18:14:43 +00008190- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8191 to ``PyTuple_SetItem``, it can be used to populate a brand new
8192 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008193
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008194- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008196- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8197 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8198 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008199
8200- Patch #1720595: add T_BOOL to the range of structmember types.
8201
8202- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8203 ``PyFloat_GetInfo()`` to the float API.
8204
Georg Brandl3ee81df2008-05-17 18:14:43 +00008205- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8206 of w# format code incorrectly truncated the length to an int, even
8207 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8208 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008209
Georg Brandl3ee81df2008-05-17 18:14:43 +00008210- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8211 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008212
Georg Brandl3ee81df2008-05-17 18:14:43 +00008213- PEP 3123: Provide forward compatibility with Python 3.0, while
8214 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8215 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008216
Georg Brandl3ee81df2008-05-17 18:14:43 +00008217- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8218 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008219
8220- Patch #1733960: Allow T_LONGLONG to accept ints.
8221
8222- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8223
Christian Heimes000a0742008-01-03 22:16:32 +00008224- Added a new API function ``PyImport_ImportModuleNoBlock``.
8225
Georg Brandl6caad7d2008-01-26 14:19:22 +00008226- Bug #1637022: Prefix AST symbols with _Py_.
8227
8228- Fix some leftovers from the conversion from int to Py_ssize_t
8229 (relevant to strings and sequences of more than 2**31 items).
8230
8231- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8232 outside of pystate.c and should not be necessary.
8233
Georg Brandl3ee81df2008-05-17 18:14:43 +00008234- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8235 absolute imports. In earlier versions they might have used relative
8236 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008237
Georg Brandl3ee81df2008-05-17 18:14:43 +00008238- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8239 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008240
Georg Brandl3ee81df2008-05-17 18:14:43 +00008241- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8242 macro so it can be used as an expression.

8247
Georg Brandl3ee81df2008-05-17 18:14:43 +00008248- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8249 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8250 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8251 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008252
Georg Brandl3ee81df2008-05-17 18:14:43 +00008253- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
8254 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00008264- buildtools now raises a DeprecationWarning.
8265
Georg Brandl3ee81df2008-05-17 18:14:43 +00008266- Removed the macfs module. It had been deprecated since Python 2.5.
8267 This lead to the deprecation of macostools.touched() as it relied
8268 solely on macfs and was a no-op under OS X.
