1158 32-bit-only installer Pythons on systems with Xcode 4 (currently
1159 OS X 10.8, 10.7, and optionally 10.6).
1160 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1161 * Since Xcode 4 removes ppc support, extension module builds now
1162 check for ppc compiler support and by default remove ppc and
1163 ppc64 archs when they are not available.
1164 * Extension module builds now revert to using system installed
1165 headers and libs (/usr and /System/Library) if the SDK used
1166 to build the interpreter is not installed or has moved.
1167 * Try to avoid building extension modules with deprecated
1168 and problematic Apple llvm-gcc compiler. If original compiler
1169 is not available, use clang instead by default.

1519
Mark Dickinsondbbed042011-09-19 16:38:08 +01001520- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1521 int.__pow__. These overflow checks were causing int.__pow__ to produce
1522 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001523 compiler optimizing the check away. Also fix similar overflow checks
1524 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1525 bugs caused test failures with recent versions of Clang.

Antoine Pitrou16166452011-07-12 22:04:20 +02001536- Issue #12149: Update the method cache after a type's dictionnary gets
1537 cleared by the garbage collector. This fixes a segfault when an instance
1538 and its type get caught in a reference cycle, and the instance's
1539 deallocator calls one of the methods on the type (e.g. when subclassing
1540 IOBase). Diagnosis and patch by Davide Rizzo.
1541
Florent Xiclunaa1f948b2012-01-24 21:05:10 +01001542- Issue #12501: Remove Py3k warning for callable. callable() is supported

Victor Stinner08563d92011-05-30 23:44:13 +02001549 the following case: sys.stdin.read() stopped with CTRL+d (end of file),
1550 raw_input() interrupted by CTRL+c.
1551
Łukasz Langa7a153902011-10-18 17:16:00 +02001552- Issue #10860: httplib now correctly handles an empty port after port
1553 delimiter in URLs.
1554

Florent Xiclunac2279652012-02-12 14:49:03 +01001593- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001594 has left two versions of customize_compiler, the original in
1595 distutils.sysconfig and another copy in distutils.ccompiler, with some
1596 parts of distutils calling one and others using the other.
1597 Complete the revert back to only having one in distutils.sysconfig as
1598 is the case in 3.x.
1599
Ned Deily0d0ea482012-02-10 12:59:06 +01001600- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1601 Distutils-based packages with C extension modules may fail because
1602 Apple has removed gcc-4.2, the version used to build python.org
1603 64-bit/32-bit Pythons. If the user does not explicitly override
1604 the default C compiler by setting the CC environment variable,
1605 Distutils will now attempt to compile extension modules with clang
1606 if gcc-4.2 is required but not found. Also as a convenience, if
1607 the user does explicitly set CC, substitute its value as the default
1608 compiler in the Distutils LDSHARED configuration variable for OS X.
1609 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1610 SDK, neither of which are available in Xcode 4. This change does not
1611 attempt to override settings to support their use with Xcode 4.)
1612

Ned Deily87e82bb2011-06-28 19:52:59 -07001861- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1862 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1863 interpreter process. This could cause failures in non-Distutils subprocesses
1864 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001865 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001866 deployment target only in the environment of each build subprocess. It is
1867 still possible to globally override the default by setting
1868 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1869 greater or equal to the default value, the value with which the interpreter
1870 was built.

1900 the ticker doesn't have to wind down to zero from the old starting point
1901 before the new interval takes effect. And if the user increases the
1902 interval, it makes sure the new limit takes effect right away rather have an
1903 early task switch before recognizing the new interval.

2884 This prevents user-created self-referencing ordered dictionaries from
2885 becoming permanently uncollectable GC garbage. The downside is that
2886 removing __del__ means that the internal doubly-linked list has to wait for
2887 GC collection rather than freeing memory immediately when the refcnt drops

3346
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003347- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3348 start byte and the continuation byte(s) are now considered invalid, instead
3349 of the number of bytes specified by the start byte.
3350 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3351 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3352 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3353 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003361- Issue #8748: Fix two issues with comparisons between complex and integer
3362 objects. (1) The comparison could incorrectly return True in some cases
3363 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3364 (2) The comparison raised an OverflowError for large integers, leading
3365 to unpredictable exceptions when combining integers and complex objects
3366 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003368- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00003505- Issue #1533: Fix inconsistency in range function argument processing: any
3506 non-float non-integer argument is now converted to an integer (if possible)
3507 using its __int__ method. Previously, only small arguments were treated this
3508 way; larger arguments (those whose __int__ was outside the range of a C long)
3509 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00003517 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00003518 benefit compared to the dynamic memory allocation fallback. Patch by
3519 Charles-François Natali.

Georg Brandlfee0f442010-05-22 21:26:21 +00003543- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing error
3544 messages when accessing undefined class attributes because of the cheap
3545 inheritance with the underlying socket object. The cheap inheritance has been
3546 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00003547

Georg Brandlfee0f442010-05-22 21:26:21 +00003559- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
3560 operation raises multiple signals and more than one of those signals is
3561 trapped, the specification determines the order in which the signals should be
3562 handled. In many cases this order wasn't being followed, leading to the wrong
3563 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00003564

3730Core and Builtins
3731-----------------
3732
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003733- Issue #7301: Add environment variable $PYTHONWARNINGS.
3734
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003735- Issue #8329: Don't return the same lists from select.select when no fds are
3736 changed.
3737
Georg Brandlfee0f442010-05-22 21:26:21 +00003738- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003739 on 64-bit machines. The shift count for either left or right shift is
3740 permitted to be up to sys.maxsize.
3741
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003742- Ensure that tokenization of identifiers is not affected by locale.
3743
Georg Brandlfee0f442010-05-22 21:26:21 +00003744- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003745
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003746- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3747
Georg Brandlfee0f442010-05-22 21:26:21 +00003748- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3749 with a non-empty format string. This is an effort to future-proof user
3750 code. If a derived class does not currently implement __format__ but later
3751 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003752 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003753 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003754
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003755- Issue #8268: Old-style classes (not just instances) now support weak
3756 references.
3757
Georg Brandlfee0f442010-05-22 21:26:21 +00003758- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
3759 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00003760
Victor Stinnerc7790ed2010-03-22 12:36:28 +00003761- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00003762
Benjamin Peterson96545892010-03-21 20:21:00 +00003763- Issue #6474: Make error message from passing an inadequate number of keyword
3764 arguments to a function correct.
3765
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003766- Issue #8164: Don't allow lambda functions to have a docstring.
3767
Victor Stinner66644262010-03-10 22:30:19 +00003768- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003769 (SIGINT). If an error occurs while importing the site module, the error is
3770 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003771 module.
3772
Collin Winter001a3952010-03-18 21:54:01 +00003773- Code objects now support weak references.

3776-------
3777
R. David Murray661303f2010-04-13 20:57:40 +00003778- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
3779
Antoine Pitrouf9de5342010-04-05 21:35:07 +00003780- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00003781 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3782 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00003783
Benjamin Peterson76a23c12010-04-04 23:23:22 +00003784- Issue #8310: Allow dis to examine new style classes.
3785
Georg Brandlfee0f442010-05-22 21:26:21 +00003786- Issue #8257: The Decimal construct now accepts a float instance directly,
3787 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003788
3789 >>> Decimal(1.1)
3790 Decimal('1.100000000000000088817841970012523233890533447265625')
3791
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003792- collections.Counter() now supports a subtract() method.
3793
Georg Brandlfee0f442010-05-22 21:26:21 +00003794- The functools module now has a total_ordering() class decorator to simplify
3795 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003796
Georg Brandlfee0f442010-05-22 21:26:21 +00003797- The functools module also adds cmp_to_key() as a tool to transition old-style
3798 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003799
Georg Brandlfee0f442010-05-22 21:26:21 +00003800- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3801 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003802
Georg Brandlfee0f442010-05-22 21:26:21 +00003803- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3804 InvalidOperation instead of returning False. (Comparisons involving a quiet
3805 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3806 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003807
Georg Brandlfee0f442010-05-22 21:26:21 +00003808- Issue #2531: Comparison operations between floats and Decimal instances now
3809 return a result based on the numeric values of the operands; previously they
3810 returned an arbitrary result based on the relative ordering of id(float) and
3811 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003812
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003813- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003814 argument `-` which tells it to read files to compile from stdin. Each line is
3815 read on demand and the named file is compiled immediately. (Original patch by
3816 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003817
Georg Brandlfee0f442010-05-22 21:26:21 +00003818- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3819 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003821- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3822 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003823 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003824
Georg Brandlfee0f442010-05-22 21:26:21 +00003825- Comparisons using one of <, <=, >, >= between a complex instance and a
3826 Fractions instance now raise TypeError instead of returning True/False. This
3827 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3828 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003829
Michael Foorde6410c52010-03-29 20:04:23 +00003830- Addition of ``WeakSet`` to the ``weakref`` module.

3838
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003839- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003840 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3841 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003842
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003843- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3844 deprecated.
3845
Georg Brandlfee0f442010-05-22 21:26:21 +00003846- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3847 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00003848

3853 existing at the same time, causing a Unicode error when configuration code
3854 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00003855
Georg Brandlfee0f442010-05-22 21:26:21 +00003856- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
3857 when logging occurs.
Vinay Sajip3017a7b2010-03-22 12:33:08 +00003858
Antoine Pitroueee91cd2010-03-26 19:27:16 +00003859- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
3860 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
3861 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +00003862
Florent Xiclunacf82fa62010-03-21 12:27:20 +00003863- Issue #8179: Fix macpath.realpath() on a non-existing path.

3877 locale.
Matthias Klose358e7ff2010-03-15 13:42:23 +00003878
Georg Brandlfee0f442010-05-22 21:26:21 +00003879- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003883- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003884 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3885 log file to compute the next rollover time. If the log file does not exist,
3886 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003887
Georg Brandlba83f822010-03-14 09:50:54 +00003888- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

3895
Georg Brandlba83f822010-03-14 09:50:54 +00003896- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3897 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3898 This is a behavior change, so email's minor version number is now bumped, to
3899 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003927- Issue #8300: When passing a non-integer argument to struct.pack with any
3928 integer format code, struct.pack first attempts to convert the non-integer
3929 using its __index__ method. If that method is non-existent or raises
3930 TypeError it goes on to try the __int__ method, as described below.
3931
Georg Brandlba83f822010-03-14 09:50:54 +00003932- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3933 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3934 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003935 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3936 inconsistent: __int__ was used for some integer codes but not for others, and
3937 the set of integer codes for which it was used differed between native packing
3938 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00004190- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4191 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4192 returning NULL. The macro now returns a statically allocated empty string

4343-----------------
4344
Georg Brandlba83f822010-03-14 09:50:54 +00004345- The ``__complex__()`` method is now looked up on the class of instances to
4346 make it consistent with other special methods.

4350
Mark Dickinson1b34d252010-01-01 17:27:30 +00004351- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004352 DeprecationWarning when passed a float argument where an integer was expected.
4353 These functions and methods now raise TypeError instead. The majority of the
4354 effects of this change are in the extension modules, but some core functions
4355 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4356 and many unicode/str methods.

4368
Georg Brandlba83f822010-03-14 09:50:54 +00004369- Issue #1811: Improve accuracy and cross-platform consistency for true division
4370 of integers: the result of a/b is now correctly rounded for ints a and b (at
4371 least on IEEE 754 platforms), and in particular does not depend on the
4372 internal representation of a long.

4380
Georg Brandlba83f822010-03-14 09:50:54 +00004381 These executables now work properly with the arch(1) command: ``arch -ppc
4382 python`` will start a universal binary version of python in PPC mode (unlike

4523 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004524

4526 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00004539- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4540 decimal string that's guaranteed to round back to x under correct rounding
4541 (with round-half-to-even rounding mode). Previously it gave a string based on
4542 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4543 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4544 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004545
Georg Brandlba83f822010-03-14 09:50:54 +00004546- Issue #7117: On almost all platforms: float-to-string and string-to-float
4547 conversions within Python are now correctly rounded. Places these conversions
4548 occur include: str for floats and complex numbers; the float and complex
4549 constructors; old-style and new-style numeric formatting; serialization and
4550 deserialization of floats and complex numbers using marshal, pickle and json;
4551 parsing of float and imaginary literals in Python code; Decimal-to-float
4552 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004553
Georg Brandlba83f822010-03-14 09:50:54 +00004554 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4555 providing correctly-rounded strtod and dtoa C functions. This code is
4556 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4557 the C compiler. There may be a small number of platforms on which correct
4558 operation of this code cannot be guaranteed, so the code is not used: notably,
4559 this applies to platforms where the C double format is not IEEE 754 binary64,
4560 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4561 and Python's configure script is unable to determine how to change the FPU
4562 precision. On these platforms conversions use the platform strtod and dtoa,
4563 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004565- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4566 uses the correctly-rounded string <-> float conversions described above (when
4567 available), and so produces correctly rounded results that will display nicely
4568 under the float repr. There are two related small changes: (1) round now
4569 accepts any class with an ``__index__()`` method for its second argument (but
4570 no longer accepts floats for the second argument), and (2) an excessively
4571 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4572 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004715 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4716 (2) parsing of strings representing infinities and nans was locale aware; and
4717 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004719- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4720 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4721 but with at least one decimal point and with a default precision
4722 of 12. Previously, the behavior the same but with a default precision of 6.
4723 This more closely matches ``str()``, and reduces surprises when adding
4724 alignment flags to the empty presentation type. This also affects the new
4725 complex.__format__ in the same way.
4726
4727- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00004903- Issue #4597: Fixed exception handling when the __exit__ function of a context
4904 manager returns a value that cannot be converted to a bool.

Georg Brandlba83f822010-03-14 09:50:54 +00004908- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4909 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4910 instances. On a typical machine this saves 3 bytes of memory (on average) per
4911 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004913- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4914 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4915 instead of throwing a MemoryError.
4916
Georg Brandlba83f822010-03-14 09:50:54 +00004917- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4918 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004919
Benjamin Petersonc078f922008-11-21 22:27:24 +00004920- Issue #4367: Python would segfault during compiling when the unicodedata
4921 module couldn't be imported and \N escapes were present.
4922
Georg Brandlba83f822010-03-14 09:50:54 +00004923- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4924 file objects with closefd=False. The file descriptor is still kept open but
4925 the file object behaves like a closed file. The ``FileIO`` object also got a
4926 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004927
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004928- Issue #4348: Some bytearray methods returned that didn't cause any change to
4929 the bytearray, returned the same bytearray instead of a copy.
4930
Georg Brandlba83f822010-03-14 09:50:54 +00004931- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

4934
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004935- Issue #4048: The parser module now correctly validates relative imports.
4936
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004937- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

4939
Georg Brandlba83f822010-03-14 09:50:54 +00004940- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4941 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00004942
Benjamin Petersonbdca9422008-10-26 20:21:13 +00004943- Issue #4209: Enabling unicode_literals and the print_function in the same
4944 __future__ import didn't work.
4945
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004946- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004947 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004948
Georg Brandlba83f822010-03-14 09:50:54 +00004949- On windows, ``os.chdir()`` given unicode was not working if
4950 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4951 this code path is really executed because I cannot move to such directory on
4952 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004953
Georg Brandlba83f822010-03-14 09:50:54 +00004954- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4955 element is temporarily replaced with an equivalent frozenset. But the
4956 eventual KeyError would always report the empty ``frozenset()`` as the missing
4957 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004958
Georg Brandlba83f822010-03-14 09:50:54 +00004959- Issue #4509: Various issues surrounding resize of bytearray objects to which
4960 there are buffer exports.

4967
Georg Brandlba83f822010-03-14 09:50:54 +00004968- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short

Matthias Klose91a3b9e2009-04-05 21:19:13 +00004971- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
4972 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00004973
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004974- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4975 returned them on 64bit platforms.
4976
Walter Dörwalded960ac2009-05-03 22:36:33 +00004977- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4978 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4979 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4980 of using the replace error handler in PyUnicode_DecodeUTF8().
4981
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004982- Issue #3739: The unicode-internal encoder now reports the number of characters
4983 consumed like any other encoder (instead of the number of bytes).
4984
Georg Brandlba83f822010-03-14 09:50:54 +00004985- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4986 allocator will be automatically disabled when running under Valgrind. This
4987 gives improved memory leak detection when running under Valgrind, while taking
4988 advantage of pymalloc at other times.

5015 from the user's group and inherit from its container when the test is run.

6158 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6159 neither __int__ nor __long__, TypeError used to be raised (with a

6357
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006358- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6359 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6360 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6361 ``printf`` function, whereas PyString_FromFormat has an independent
6362 implementation and uses "%zd" on all platforms for size_t values.
6363 This makes a difference on win64, where ``printf`` needs "%Id" to display
6364 64bit values.

6370 object; previously an int would be returned for small values. the __long__
6371 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006381 was correctly parsed but parsing of subsequent arguments failed.
6382
Vinay Sajip35e3b032008-09-01 14:33:59 +00006383- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006384 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6385 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6386 when given a tuple of classes as second argument, were looking up
6387 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6388 type object.

6534
Guido van Rossumf8402962008-08-20 15:01:50 +00006535- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6536 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6537 extensions do not automatically benefit from the class attribute
6538 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6539 to their tp_flags field if they care. This is a backwards
6540 compatibility feature; in 3.0, all types will use the cache by
6541 default.
6542
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006543- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00006556- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6557 ValueError consistently across platforms.
6558
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006559- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6560 (64bit Unix, for example), unichr() would truncate its argument and return
6561 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6562
Neal Norwitze7d8be82008-07-31 17:17:14 +00006563- Apply security patches from Apple.
6564
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006565- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6566 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6567
Antoine Pitrou92f82162008-07-25 22:22:08 +00006568- Issue #1819: function calls with several named parameters are now on
6569 average 35% faster (as measured by pybench).
6570
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006571- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6572 the python debugger steps into a class statement: the free variables (local
6573 variables defined in an outer scope) would be deleted from the outer scope.
6574
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006575- Issue #2620: Overflow checking when allocating or reallocating memory
6576 was not always being done properly in some python types and extension
6577 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6578 all been updated to perform better checks and places in the code that
6579 would previously leak memory on the error path when such an allocation
6580 failed have been fixed.

6586
Benjamin Petersone977ad42008-08-20 01:42:01 +00006587- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6588 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6589
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006590- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6591 version reported by these tools does not necessarily follow the python
6592 version numbering scheme, so the module is less strict when parsing it.
6593
Nick Coghlanf70385a2008-08-18 12:42:46 +00006594- Issue #2235: Added Py3k warnings for types which will become unhashable
6595 under the stricter __hash__ inheritance rules in 3.0. Several types
6596 which did not meet the rules for hash invariants and were already
6597 unhashable in 3.0 have now been explicitly flagged as unhashable in
6598 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6599 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6600
Brett Cannon88f801d2008-08-18 00:46:22 +00006601- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6602 imported into the module but exposed as part of the module's API.

Brett Cannonbf3157b2008-08-14 05:00:03 +00006632- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6633 since mimetools itself is deprecated. Because modules are cached, all
6634 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6635
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006636- Issue #3134: shutil referenced undefined WindowsError symbol.

6645 a MemoryError rather than silently stop the iteration.
6646
Guido van Rossum59ce9012008-08-09 14:55:34 +00006647- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6648 to _sre.compile() will now be rejected. This should not affect anybody
6649 since the re.compile() function never generates invalid re-bytecode.
6650
Skip Montanaroa032bf42008-08-08 22:52:51 +00006651- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6652 upon first access it can be automatically initialized from the csv file if
6653 it wasn't initialized during instantiation.
6654
Brett Cannon3aa2a492008-08-06 22:28:09 +00006655- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6656 the reload() built-in has been removed.
6657
Brett Cannon7e30b672008-08-04 21:52:25 +00006658- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006659 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6667 raised an AttributeError.
6668

Antoine Pitroude781a42008-08-09 12:43:23 +00006670 asking for a specific length. This problem only affected files opened
6671 using the new "io" module, not the built-in open() function.

6697 file name rather than a ZipInfo instance, so files are extracted with
6698 mode 0600 rather than 000 under Unix.
6699
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006700- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6701 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006712- Issue #2235: the C API function PyObject_HashNotImplemented and its
6713 interaction with the tp_hash slot (added in 2.6b2) are now documented
6714
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006715- Issue #643841: The language reference now provides more detailed
6716 coverage of the lookup process for special methods. The disclaimers
6717 regarding lack of coverage of new-style classes have also been
6718 removed, since the coverage is now fairly reasonable.

6722================================
6723
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006724*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006726Core and Builtins
6727-----------------
6728
Georg Brandl3e483f62008-07-16 22:57:41 +00006729- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6730 its methods now allow for items objects that can be converted to
6731 an integer using operator.index().
6732
Mark Dickinson64b7e502008-07-16 09:40:03 +00006733- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6734 produced a ValueError instead of giving the correct float.
6735
Eric Smitha5fa5a22008-07-16 00:11:49 +00006736- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6737 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6738
Mark Dickinson7103aa42008-07-15 19:08:33 +00006739- Issue #3008: the float type has a new instance method 'float.hex'
6740 and a new class method 'float.fromhex' to convert floating-point
6741 numbers to and from hexadecimal strings, respectively.
6742
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006743- Issue #2235: __hash__ is once again inherited by default. To allow
6744 collections.Hashable to remain meaningful in the presence of the
6745 default hash implementation (object.__hash__), it is now possible
6746 to explicit block inheritance of hash by setting __hash__=None at
6747 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6748 level.
6749
Nick Coghlanb028f502008-07-13 14:52:36 +00006750- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6751 the parent module cannot be found while performing an absolute import.
6752 This means that an incorrectly defined __package__ attribute will
6753 now only prevent relative imports in that module rather than causing
6754 all imports from that module to fail.
6755
Nick Coghlan14ff9942008-07-08 14:21:42 +00006756- Issue #2517: Allow unicode messages in Exceptions again by correctly
6757 bypassing the instance dictionary when looking up __unicode__ on
6758 new-style classes.
6759
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006760- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6761 set to a custom object whose write() method happens to install
6762 another file in sys.stdout.
6763
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006764- Issue #3088: Corrected a race condition in classes derived from
6765 threading.local: the first member set by a thread could be saved in
6766 another thread's dictionary.
6767
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006768- Issue #3004: Minor change to slice.indices(): the start and stop
6769 arguments are now treated identically, making the behaviour easier
6770 to describe and understand. For example, slice(None, -10,
6771 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6772 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6773 10, -1).
6774
Georg Brandl278fc502008-07-19 12:46:12 +00006775- Issue #3219: Calling a function with repeated keyword arguments,
6776 f(a=2, a=23), would not cause a syntax error. This was a regression
6777 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006778
Georg Brandl278fc502008-07-19 12:46:12 +00006779- Issue #2862: Make int and float freelist management consistent with
6780 other freelists. Changes their CompactFreeList apis into
6781 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006782

6784-------
6785
Thomas Heller57adf222008-08-14 19:10:48 +00006786- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6787 api functions without holding the GIL, which could lead to a fatal
6788 error when they failed.
6789
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006790- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6799 ForkingPickler.register() to resolve conflict with ctypes.
6800
Vinay Sajip51e65192008-07-18 09:01:10 +00006801- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00006803- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6804 a valid dlerror() message.
6805
Thomas Heller2bad6572008-07-15 17:19:50 +00006806- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6807 incomplete structure was created.
6808
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006809- Issue #3339: dummy_thread.acquire() should not return None.

6812
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006813- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006814
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006815- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6816 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006817 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006818 content-length. The problem had been corrected in the 2.4 branch, but never
6819 merged into trunk.
6820
Georg Brandle78fbcc2008-07-05 10:13:36 +00006821- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00006831- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006832 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006833
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006834- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007227 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007228
7229 This is controlled by the configure argument ``--with-universal-archs``:
7230
7231 - ``--with-universal-archs=all``: install 4-way universal
7232
7233 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7234
7235 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7236
7237 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007289- Issue #1631171: Re-implement the 'warnings' module in C (the
7290 original Python code has been kept as backup). This will allow for
7291 using the 'warning's machinery in such places as the parser where
7292 use of pure Python code is not possible. Both the ``showarning()``
7293 and ``formatwarning()`` gain an optional 'line' argument which is
7294 not called by default for backwards-compatibility reasons. Setting
7295 ``warnings.showwarning()`` to an implementation that lacks support
7296 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007359- Issue #2550: The approach used by client/server code for obtaining
7360 ports to listen on in network-oriented tests has been refined in an
7361 effort to facilitate running multiple instances of the entire
7362 regression test suite in parallel without issue.
7363 test_support.bind_port() has been fixed such that it will always
7364 return a unique port -- which wasn't always the case with the
7365 previous implementation, especially if socket options had been set
7366 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7367 new implementation of bind_port() will actually raise an exception
7368 if it is passed an AF_INET/SOCK_STREAM socket with either the
7369 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7370 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7371 the socket it's been passed. This currently only applies to
7372 Windows. This option prevents any other sockets from binding to the
7373 host/port we've bound to, thus removing the possibility of the
7374 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7375 when a second SOCK_STREAM socket binds and accepts to a host/port
7376 that's already been bound by another socket. The optional preferred
7377 port parameter to bind_port() has been removed. Under no
7378 circumstances should tests be hard coding ports!
7379
7380 test_support.find_unused_port() has also been introduced, which will
7381 pass a temporary socket object to bind_port() in order to obtain an
7382 unused port. The temporary socket object is then closed and
7383 deleted, and the port is returned. This method should only be used
7384 for obtaining an unused port in order to pass to an external program
7385 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7386 a parameter to a server-oriented class that doesn't give you direct
7387 access to the underlying socket used.
7388
7389 Finally, test_support.HOST has been introduced, which should be used
7390 for the host argument of any relevant socket calls (i.e. bind and
7391 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007392
7393 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007394 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007395 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7396 test_asynchat and test_socket_ssl.
7397
Georg Brandl3ee81df2008-05-17 18:14:43 +00007398 It is now possible for multiple instances of the regression test
7399 suite to run in parallel without issue.

7666-----------------
7667
Fred Drakea8ee94b2008-03-01 02:45:07 +00007668- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007669 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007670
Georg Brandlad61bc82008-02-23 15:11:18 +00007671- Issue #2067: file.__exit__() now calls subclasses' close() method.
7672
7673- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007674
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007675- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007676 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007677
Eric Smitha73fbe72008-02-23 03:09:44 +00007678- Added the future_builtins module, which contains hex() and oct().
7679 These are the PEP 3127 version of these functions, designed to be
7680 compatible with the hex() and oct() builtins from Python 3.0. They
7681 differ slightly in their output formats from the existing, unchanged
7682 Python 2.6 builtins. The expected usage of the future_builtins
7683 module is:
7684 from future_builtins import hex, oct
7685
Eric Smith7ef40bf2008-02-20 23:34:22 +00007686- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7687 exponents for exponents with absolute value < 100. Follows C99
7688 standard. This is a change on Windows, which would use 3 digits.
7689 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7690 so that any alterations it does to the resulting string will be
7691 available in stringlib/formatter.h (for float.__format__).
7692
Eric Smith5a3c1352008-02-19 13:21:56 +00007693- Implemented PEP 3101, Advanced String Formatting. This adds a new
7694 builtin format(); a format() method for str and unicode; a
7695 __format__() method to object, str, unicode, int, long, float, and
7696 datetime; the class string.Formatter; and the C API
7697 PyObject_Format().
7698
Georg Brandl3ee81df2008-05-17 18:14:43 +00007699- Fixed several potential crashes, all caused by specially crafted
7700 __del__ methods exploiting objects in temporarily inconsistent
7701 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007702
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007703- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007704 prevent a possible crash: an Abstract Base Class would try to access
7705 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007706
Georg Brandl3ee81df2008-05-17 18:14:43 +00007707- Fixed repr() and str() of complex numbers with infinity or nan as
7708 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007709
Georg Brandl3ee81df2008-05-17 18:14:43 +00007710- Clear all free lists during a gc.collect() of the highest generation
7711 in order to allow pymalloc to free more arenas. Python may give back
7712 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007713
Georg Brandl3ee81df2008-05-17 18:14:43 +00007714- Issue #2045: Fix an infinite recursion triggered when printing a
7715 subclass of collections.defaultdict, if its default_factory is set
7716 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007717
Christian Heimesf75dbef2008-02-08 00:11:31 +00007718- Fixed a minor memory leak in dictobject.c. The content of the free
7719 list was not freed on interpreter shutdown.
7720
Georg Brandl21e99f42010-03-07 15:23:59 +00007721- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007722 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007723
Georg Brandl3ee81df2008-05-17 18:14:43 +00007724- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7725 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007726 to compact the internal free lists of pre-allocted ints and floats.
7727
Georg Brandl3ee81df2008-05-17 18:14:43 +00007728- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7729 calls. Python expected the return type int but the fork familie
7730 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007731
Georg Brandl3ee81df2008-05-17 18:14:43 +00007732- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7733 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007734
Georg Brandl3ee81df2008-05-17 18:14:43 +00007735- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7736 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007737
Georg Brandl3ee81df2008-05-17 18:14:43 +00007738- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7739 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007740
Georg Brandl3ee81df2008-05-17 18:14:43 +00007741- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7742 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007743
Georg Brandl3ee81df2008-05-17 18:14:43 +00007744- Patch #1473257: generator objects gain a gi_code attribute. This is
7745 the same object as the func_code attribute of the function that
7746 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007747
Georg Brandl3ee81df2008-05-17 18:14:43 +00007748- Issue #1920: "while 0" statements were completely removed by the
7749 compiler, even in the presence of an "else" clause, which is
7750 supposed to be run when the condition is false. Now the compiler
7751 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007752
Guido van Rossumeead05f2008-01-24 18:21:02 +00007753- A few crashers fixed: weakref_in_del.py (issue #1377858);
7754 loosing_dict_ref.py (issue #1303614, test67.py);
7755 borrowed_ref_[34].py (not in tracker).
7756
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007757- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007758 suppressed while an extension is loaded by calling SetErrorMode in
7759 dynload_win.c. The error is still reported properly.
7760
Georg Brandl3ee81df2008-05-17 18:14:43 +00007761- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007762 several extension methods and modules do not work without unicode
7763 support.
7764
Georg Brandl26543b12008-01-21 18:36:51 +00007765- Issue #1882: when compiling code from a string, encoding cookies in the
7766 second line of code were not always recognized correctly.
7767
Georg Brandl14404b62008-01-19 19:27:05 +00007768- Issue #1679: "0x" was taken as a valid integer literal.
7769
Georg Brandl6caad7d2008-01-26 14:19:22 +00007770- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007771 added.
7772
Christian Heimesc94e2b52008-01-14 04:13:37 +00007773- sys.float_info / PyFloat_GetInfo: The floating point information
7774 object was converted from a dict to a specialized structseq object.
7775
Georg Brandl3ee81df2008-05-17 18:14:43 +00007776- Patch #1816: Added sys.flags structseq. It exposes the status of
7777 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007778
Georg Brandl3ee81df2008-05-17 18:14:43 +00007779- Objects/structseq.c: Implemented new structseq representation. The
7780 patch makes structseqs (e.g. the return value of os.stat) more
7781 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007782
Georg Brandl3ee81df2008-05-17 18:14:43 +00007783- Patch #1700288: added a type attribute cache that caches method
7784 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007785
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007786- Bug #1776: __import__() no longer accepts filenames on any platform.
7787 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007788
Georg Brandlaed6c662008-01-07 17:25:53 +00007789- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7790
Georg Brandl3ee81df2008-05-17 18:14:43 +00007791- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7792 envvar and sys.dont_write_bytecode attribute. All these can be set
7793 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007794
Georg Brandl3ee81df2008-05-17 18:14:43 +00007795- Improve some exception messages when Windows fails to load an
7796 extension module. Now we get for example '%1 is not a valid Win32
7797 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007798
Georg Brandl3ee81df2008-05-17 18:14:43 +00007799- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007801- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7802 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007803
Christian Heimes0a8143f2007-12-18 23:22:54 +00007804- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007805 and INF. float("nan"), float("inf") and float("-inf") now work on
7806 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007807
Georg Brandl3ee81df2008-05-17 18:14:43 +00007808- Compiler now generates simpler and faster code for dictionary
7809 literals. The oparg for BUILD_MAP now indicates an estimated
7810 dictionary size. There is a new opcode, STORE_MAP, for adding
7811 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007812
Georg Brandl3ee81df2008-05-17 18:14:43 +00007813- Issue #1638: %zd configure test fails on Linux.

7826 __package__ attribute.
7827
Georg Brandl3ee81df2008-05-17 18:14:43 +00007828- Issue #1402: Fix a crash on exit, when another thread is still
7829 running, and if the deallocation of its frames somehow calls the
7830 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007831

7841 file can now be directly executed by passing their name to the
7842 interpreter. The directory/zipfile is automatically inserted as the
7843 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007844
Georg Brandl3ee81df2008-05-17 18:14:43 +00007845- Issue #1265: Fix a problem with sys.settrace, if the tracing
7846 function uses a generator expression when at the same time the
7847 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007848
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007849- sets and frozensets now have an isdisjoint() method.
7850
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007851- optimize the performance of builtin.sum().
7852
Neal Norwitz44f326e2007-10-05 05:29:17 +00007853- Fix warnings found by the new version of the Coverity checker.
7854
Georg Brandl21e99f42010-03-07 15:23:59 +00007855- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007856 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7857 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007858
Georg Brandl3ee81df2008-05-17 18:14:43 +00007859- Issue #1686386: Tuple's tp_repr did not take into account the
7860 possibility of having a self-referential tuple, which is possible
7861 from C code. Nor did object's tp_str consider that a type's tp_str
7862 could do something that could lead to an inifinite recursion.
7863 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7864 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007865
Georg Brandl3ee81df2008-05-17 18:14:43 +00007866- Issue #1164: It was possible to trigger deadlock when using the
7867 'print' statement to write to a file since the GIL was not released
7868 as needed. Now PyObject_Print() does the right thing along with
7869 various tp_print implementations of the built-in types and those in
7870 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007871
Georg Brandl3ee81df2008-05-17 18:14:43 +00007872- Issue #1147: Exceptions were directly allowing string exceptions in
7873 their throw() method even though string exceptions no longer
7874 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007875
Georg Brandl3ee81df2008-05-17 18:14:43 +00007876- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00007879- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007880 PyObject_Call() never calling back out to Python code to trigger
7881 recursion depth updates/checks. Required the creation of a static
7882 RuntimeError instance in case normalizing an exception put the
7883 recursion check value past its limit. Fixes crashers
7884 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007885
Georg Brandl3ee81df2008-05-17 18:14:43 +00007886- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007899- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007900 __*__ attributes. (Some already existed, e.g., __doc__ and
7901 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00007910 "except E as target:". This is to provide forwards compatibility
7911 with Python 3.0.

7931
Guido van Rossum143b5642007-03-23 04:58:42 +00007932- Bug #1683368: The object.__init__() and object.__new__() methods are
7933 now stricter in rejecting excess arguments. The only time when
7934 either allows excess arguments is when it is not overridden and the
7935 other one is. For backwards compatibility, when both are
7936 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007937 warning later). Also, type.__init__() insists on the same signature
7938 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007940- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7941 object to complex using its __complex__() method before falling back
7942 to the __float__() method. Therefore, the functions in the cmath
7943 module now can operate on objects that define a __complex__()
7944 method.

7961
Georg Brandl7b9c5552007-03-12 14:30:05 +00007962- Bug #1678647: write a newline after printing an exception in any
7963 case, even when converting the value to a string failed.
7964
Georg Brandl871f1bc2007-03-12 13:17:36 +00007965- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007966 its argument, if it exists. If not, it will work like before. This
7967 allows customizing the output of dir() in the presence of a
7968 __getattr__().

7978 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007979
Georg Brandlaa2321b2007-03-07 00:40:28 +00007980- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007981 makes the filenames the warning module prints much more sensible
7982 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007995- Patch #1674228: when assigning a slice (old-style), check for the
7996 sq_ass_slice instead of the sq_slice slot.
7997
Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00008624- unittest now verifies more of its assumptions. In particular,
8625 TestCase and TestSuite subclasses (not instances) are no longer
8626 accepted in TestSuite.addTest(). This should cause no
8627 incompatibility since it never made sense with ordinary subclasses
8628 -- the failure just occurred later, with a more cumbersome
8629 exception.

8907 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008908
Georg Brandl3ee81df2008-05-17 18:14:43 +00008909- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008910 that the SMTP.starttls() caller no longer needs to call ehlo()
8911 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008912 does not claim to support starttls. Adds the
8913 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8994 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8995 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00009012 time so that opening a database previously created with the DB_DUP
9013 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9014 opens. Specifically: dictionary assignment to a DB object will
9015 replace all values for a given key when the database allows
9016 duplicate values. DB users should use DB.put(k, v) when they want
9017 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009018

9024 characters with ASCII value less than 32. Also, it correctly quotes
9025 dots only if they occur on a single line, as opposed to the previous
9026 behavior of quoting dots if they are the second character of any
9027 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009361- Unified naming convention for free lists and their limits. All free
9362 lists in Object/ are named ``free_list``, the counter ``numfree``
9363 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9364 #ifndef block.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009366- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9367 to ``PyTuple_SetItem``, it can be used to populate a brand new
9368 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00009370- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009372- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
9373 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
9374 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009375
9376- Patch #1720595: add T_BOOL to the range of structmember types.
9377
9378- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
9379 ``PyFloat_GetInfo()`` to the float API.
9380
Georg Brandl3ee81df2008-05-17 18:14:43 +00009381- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9382 of w# format code incorrectly truncated the length to an int, even
9383 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9384 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009385
Georg Brandl3ee81df2008-05-17 18:14:43 +00009386- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
9387 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009388
Georg Brandl3ee81df2008-05-17 18:14:43 +00009389- PEP 3123: Provide forward compatibility with Python 3.0, while
9390 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
9391 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009392
Georg Brandl3ee81df2008-05-17 18:14:43 +00009393- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
9394 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009395
9396- Patch #1733960: Allow T_LONGLONG to accept ints.
9397
9398- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
9399
Christian Heimes000a0742008-01-03 22:16:32 +00009400- Added a new API function ``PyImport_ImportModuleNoBlock``.
9401
Georg Brandl6caad7d2008-01-26 14:19:22 +00009402- Bug #1637022: Prefix AST symbols with _Py_.
9403
9404- Fix some leftovers from the conversion from int to Py_ssize_t
9405 (relevant to strings and sequences of more than 2**31 items).
9406
9407- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9408 outside of pystate.c and should not be necessary.
9409
Georg Brandl3ee81df2008-05-17 18:14:43 +00009410- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9411 absolute imports. In earlier versions they might have used relative
9412 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009413
Georg Brandl3ee81df2008-05-17 18:14:43 +00009414- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9415 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009416
Georg Brandl3ee81df2008-05-17 18:14:43 +00009417- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
9418 macro so it can be used as an expression.

9423
Georg Brandl3ee81df2008-05-17 18:14:43 +00009424- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9425 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
9426 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
9427 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00009428
Georg Brandl3ee81df2008-05-17 18:14:43 +00009429- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
9430 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00009440- buildtools now raises a DeprecationWarning.
9441
Georg Brandl3ee81df2008-05-17 18:14:43 +00009442- Removed the macfs module. It had been deprecated since Python 2.5.
9443 This lead to the deprecation of macostools.touched() as it relied
9444 solely on macfs and was a no-op under OS X.
