1101 In particular, fix extension module build failures when trying to use
1102 32-bit-only installer Pythons on systems with Xcode 4 (currently
1103 OS X 10.8, 10.7, and optionally 10.6).
1104 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1105 * Since Xcode 4 removes ppc support, extension module builds now
1106 check for ppc compiler support and by default remove ppc and
1107 ppc64 archs when they are not available.
1108 * Extension module builds now revert to using system installed
1109 headers and libs (/usr and /System/Library) if the SDK used
1110 to build the interpreter is not installed or has moved.
1111 * Try to avoid building extension modules with deprecated
1112 and problematic Apple llvm-gcc compiler. If original compiler
1113 is not available, use clang instead by default.

Ned Deilyc47a4592012-02-11 20:40:24 +01001538 has left two versions of customize_compiler, the original in

Ned Deily0d0ea482012-02-10 12:59:06 +01001544- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1545 Distutils-based packages with C extension modules may fail because
1546 Apple has removed gcc-4.2, the version used to build python.org
1547 64-bit/32-bit Pythons. If the user does not explicitly override
1548 the default C compiler by setting the CC environment variable,
1549 Distutils will now attempt to compile extension modules with clang
1550 if gcc-4.2 is required but not found. Also as a convenience, if
1551 the user does explicitly set CC, substitute its value as the default
1552 compiler in the Distutils LDSHARED configuration variable for OS X.
1553 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1554 SDK, neither of which are available in Xcode 4. This change does not
1555 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001805- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1806 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1807 interpreter process. This could cause failures in non-Distutils subprocesses
1808 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001809 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001810 deployment target only in the environment of each build subprocess. It is
1811 still possible to globally override the default by setting
1812 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1813 greater or equal to the default value, the value with which the interpreter
1814 was built.

1844 the ticker doesn't have to wind down to zero from the old starting point
1845 before the new interval takes effect. And if the user increases the
1846 interval, it makes sure the new limit takes effect right away rather have an
1847 early task switch before recognizing the new interval.

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00002672- Issue #9869: Make long() and PyNumber_Long return something of type
2673 long for a class whose __long__ method returns a plain int. This
2674 fixes an interpreter crash when initializing an instance of a long

2680 thread-local storage key.
2681
Victor Stinnercaafd772010-09-08 10:51:01 +00002682- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
2683 encoding and errors attributes instead of using utf-8 in strict mode, to get
2684 the same behaviour than the print statement.
2685
Antoine Pitrou9cf85f12010-09-01 21:17:34 +00002686- Issue #9737: Fix a crash when trying to delete a slice or an item from

2699 output with no type specifier failed to match the str output:
2700
2701 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2702 - format(complex(0.0, 2.0), '-') included a sign and parentheses.
2703

2798 received. Now sendall() properly calls signal handlers if necessary,

2811 handles non-blocking readinto() returning None correctly.

2814 SSLSocket.sendto() to match the corresponding socket methods. Also,
2815 fix various SSLSocket methods to raise socket.error rather than an
2816 unhelpful TypeError when called on an unconnected socket. Original patch
2817 by Andrew Bennetts.
2818
Raymond Hettinger74f869e2010-09-13 22:14:36 +00002819- Issue #9826: OrderedDict.__repr__ can now handle self-referential
2820 values: d['x'] = d.
2821
Victor Stinner8fc843b2010-09-17 23:35:50 +00002822- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.

Antoine Pitroue4195e82010-09-12 14:56:27 +00002824- Issue #9837: The read() method of ZipExtFile objects (as returned by

2826
Raymond Hettinger20397532010-09-12 02:11:45 +00002827- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2828 This prevents user-created self-referencing ordered dictionaries from
2829 becoming permanently uncollectable GC garbage. The downside is that
2830 removing __del__ means that the internal doubly-linked list has to wait for
2831 GC collection rather than freeing memory immediately when the refcnt drops
2832 to zero.
2833
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002834- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002835 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002836 value.
2837
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002838- Issue #9792: In case of connection failure, socket.create_connection()
2839 would swallow the exception and raise a new one, making it impossible
2840 to fetch the original errno, or to filter timeout errors. Now the
2841 original error is re-raised.
2842
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002843- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2844 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2845 be updated back after the system call. Original patch by Brian Brazil.
2846
Antoine Pitroudca9de92010-09-04 17:52:26 +00002847- Issue #1100562: Fix deep-copying of objects derived from the list and

2852
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002853- Issue #808164: Fixed socket.close to avoid references to globals, to
2854 avoid issues when socket.close is called from a __del__ method.
2855
Terry Reedyd2d2ae92010-11-11 23:22:19 +00002856- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which

2858 heuristic. Patch by Terry Reedy and Eli Bendersky
2859
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002860- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2861 falling into recursion.
2862
R. David Murray7c4bf552010-08-25 01:45:57 +00002863- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2864 character years even if the message contains RFC822 two character years.
2865
Daniel Stutzbach91287322010-08-24 21:09:30 +00002866- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00002877- Issue #9214: Set operations on KeysView or ItemsView in the collections
2878 module now correctly return a set. (Patch by Eli Bendersky.)
2879
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002880- Issue #9617: Signals received during a low-level write operation aren't
2881 ignored by the buffered IO layer anymore.
2882
Benjamin Peterson52c36052010-08-21 03:03:22 +00002883- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2884 are not held onto after they are deleted elsewhere.
2885
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002886- Issue #9626: the view methods for collections.OrderedDict() were returning
2887 the unordered versions inherited from dict. Those methods are now
2888 overridden to provide ordered views.
2889
Éric Araujo0389ae62010-08-14 03:07:46 +00002890- Issue #8688: MANIFEST files created by distutils now include a magic
2891 comment indicating they are generated. Manually maintained MANIFESTs
2892 without this marker will not be overwritten or removed.
2893
Antoine Pitroue1436d12010-08-12 15:25:51 +00002894- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2895 and a BadZipfile error is raised if it doesn't match (as used to be the
2896 case in Python 2.5 and earlier).
2897
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002898- Issue #9550: a BufferedReader could issue an additional read when the
2899 original read request had been satisfied, which could block indefinitely
2900 when the underlying raw IO channel was e.g. a socket. Report and original
2901 patch by Jason V. Miller.
2902
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002903- Issue #9551: Don't raise TypeError when setting the value to None for

2920
Senthil Kumarane677ecf2010-08-08 11:56:31 +00002921- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2922 This is how it is supposed to work, wget and curl do the same. Previous
2923 behavior was wrong.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003291- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3292 start byte and the continuation byte(s) are now considered invalid, instead
3293 of the number of bytes specified by the start byte.
3294 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3295 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3296 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3297 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003305- Issue #8748: Fix two issues with comparisons between complex and integer
3306 objects. (1) The comparison could incorrectly return True in some cases
3307 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3308 (2) The comparison raised an OverflowError for large integers, leading
3309 to unpredictable exceptions when combining integers and complex objects

3693 with a non-empty format string. This is an effort to future-proof user
3694 code. If a derived class does not currently implement __format__ but later
3695 adds its own __format__, it would most likely break user code that had

3729
Georg Brandlfee0f442010-05-22 21:26:21 +00003730- Issue #8257: The Decimal construct now accepts a float instance directly,
3731 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003732
3733 >>> Decimal(1.1)
3734 Decimal('1.100000000000000088817841970012523233890533447265625')
3735

Georg Brandlfee0f442010-05-22 21:26:21 +00003747- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3748 InvalidOperation instead of returning False. (Comparisons involving a quiet
3749 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3750 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003751
Georg Brandlfee0f442010-05-22 21:26:21 +00003752- Issue #2531: Comparison operations between floats and Decimal instances now
3753 return a result based on the numeric values of the operands; previously they
3754 returned an arbitrary result based on the relative ordering of id(float) and
3755 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003756
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003757- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003758 argument `-` which tells it to read files to compile from stdin. Each line is
3759 read on demand and the named file is compiled immediately. (Original patch by
3760 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003761
Georg Brandlfee0f442010-05-22 21:26:21 +00003762- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

3766 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003767 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003768
Georg Brandlfee0f442010-05-22 21:26:21 +00003769- Comparisons using one of <, <=, >, >= between a complex instance and a
3770 Fractions instance now raise TypeError instead of returning True/False. This
3771 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3772 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003773

Georg Brandlfee0f442010-05-22 21:26:21 +00003828 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3829 log file to compute the next rollover time. If the log file does not exist,

Georg Brandlba83f822010-03-14 09:50:54 +00003840- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3841 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3842 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003871- Issue #8300: When passing a non-integer argument to struct.pack with any
3872 integer format code, struct.pack first attempts to convert the non-integer
3873 using its __index__ method. If that method is non-existent or raises
3874 TypeError it goes on to try the __int__ method, as described below.
3875
Georg Brandlba83f822010-03-14 09:50:54 +00003876- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3877 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3878 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003879 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3880 inconsistent: __int__ was used for some integer codes but not for others, and
3881 the set of integer codes for which it was used differed between native packing
3882 and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004189- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004190 file position when calling `truncate()`. It would previously change the file
4191 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004192 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +00004194- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4195 class used to represent files stored inside an archive. The new
4196 implementation is significantly faster and can be wrapped in a
4197 ``io.BufferedReader`` object for more speedups. It also solves an issue
4198 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4287-----------------
4288
Georg Brandlba83f822010-03-14 09:50:54 +00004289- The ``__complex__()`` method is now looked up on the class of instances to
4290 make it consistent with other special methods.

4294
Mark Dickinson1b34d252010-01-01 17:27:30 +00004295- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004296 DeprecationWarning when passed a float argument where an integer was expected.
4297 These functions and methods now raise TypeError instead. The majority of the
4298 effects of this change are in the extension modules, but some core functions
4299 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4300 and many unicode/str methods.

4314 of integers: the result of a/b is now correctly rounded for ints a and b (at
4315 least on IEEE 754 platforms), and in particular does not depend on the
4316 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004325 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004465- Issue #3382: 'F' formatting for float and complex now convert the result to
4466 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4467 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004468
Georg Brandlba83f822010-03-14 09:50:54 +00004469- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4470 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004471
Georg Brandlba83f822010-03-14 09:50:54 +00004472- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4473 1e-100 used to raise OverflowError, but now gives the requested 120
4474 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00004475

4481 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004482
Georg Brandlba83f822010-03-14 09:50:54 +00004483- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4484 decimal string that's guaranteed to round back to x under correct rounding
4485 (with round-half-to-even rounding mode). Previously it gave a string based on
4486 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4487 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4488 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004489
Georg Brandlba83f822010-03-14 09:50:54 +00004490- Issue #7117: On almost all platforms: float-to-string and string-to-float
4491 conversions within Python are now correctly rounded. Places these conversions
4492 occur include: str for floats and complex numbers; the float and complex
4493 constructors; old-style and new-style numeric formatting; serialization and
4494 deserialization of floats and complex numbers using marshal, pickle and json;
4495 parsing of float and imaginary literals in Python code; Decimal-to-float
4496 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004497
Georg Brandlba83f822010-03-14 09:50:54 +00004498 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4499 providing correctly-rounded strtod and dtoa C functions. This code is
4500 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4501 the C compiler. There may be a small number of platforms on which correct
4502 operation of this code cannot be guaranteed, so the code is not used: notably,
4503 this applies to platforms where the C double format is not IEEE 754 binary64,
4504 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4505 and Python's configure script is unable to determine how to change the FPU
4506 precision. On these platforms conversions use the platform strtod and dtoa,
4507 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004508
Georg Brandlba83f822010-03-14 09:50:54 +00004509- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4510 uses the correctly-rounded string <-> float conversions described above (when
4511 available), and so produces correctly rounded results that will display nicely
4512 under the float repr. There are two related small changes: (1) round now
4513 accepts any class with an ``__index__()`` method for its second argument (but
4514 no longer accepts floats for the second argument), and (2) an excessively
4515 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4516 raises an exception.

4519
Georg Brandlba83f822010-03-14 09:50:54 +00004520- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00004659 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4660 (2) parsing of strings representing infinities and nans was locale aware; and
4661 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004663- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4664 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4665 but with at least one decimal point and with a default precision
4666 of 12. Previously, the behavior the same but with a default precision of 6.
4667 This more closely matches ``str()``, and reduces surprises when adding
4668 alignment flags to the empty presentation type. This also affects the new
4669 complex.__format__ in the same way.
4670
4671- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4672 classtype's, even if it was None. property now inserts the __doc__ into the
4673 subclass instance __dict__.

4900 eventual KeyError would always report the empty ``frozenset()`` as the missing

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00006281 AttributeError instead of RuntimeError, depending in which C API call
6282 exactly the recursion limit is exceeded. Consequently, both exception types
6283 are caught and silenced.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006300- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6301
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006302- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6303 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6304 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6305 ``printf`` function, whereas PyString_FromFormat has an independent
6306 implementation and uses "%zd" on all platforms for size_t values.
6307 This makes a difference on win64, where ``printf`` needs "%Id" to display
6308 64bit values.
6309
Benjamin Peterson97179b02008-09-09 20:55:01 +00006310- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6311 error.
6312
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006313- Issue #3777: long() applied to a float object now always return a long
6314 object; previously an int would be returned for small values. the __long__
6315 method is allowed to return either an int or a long, but the behaviour of
6316 float objects should not change to respect backward compatibility.
6317
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006318- Issue #3751: str.rpartition would perform a left-partition when called with
6319 a unicode argument.
6320
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006321- Issue #3683: Fix compilation when --without-threads is given.
6322
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006323- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006324 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006325 was correctly parsed but parsing of subsequent arguments failed.
6326
Vinay Sajip35e3b032008-09-01 14:33:59 +00006327- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006328 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6329 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6330 when given a tuple of classes as second argument, were looking up
6331 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6332 type object.
6333
Neal Norwitz18aa3882008-08-24 05:04:52 +00006334- Fix crashes on memory allocation failure found with failmalloc.
6335
6336- Fix memory leaks found with valgrind and update suppressions file.
6337
6338- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6339
6340- Fix problem using wrong name in decimal module reported by pychecker.
6341
Christian Heimes7d4c3172008-08-22 19:47:25 +00006342- Silenced another compiler warning about a used but not defined
6343 function 'stringlib_contains_obj'.
6344
Benjamin Peterson712ee922008-08-24 18:10:20 +00006345- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6346 ``__delslice__``.
6347
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006348- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6349 library targets in the Makefile.
6350
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006351- Issue #1204: The configure script now tests for additional libraries
6352 that may be required when linking against readline. This fixes issues
6353 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon672237d2008-09-09 00:49:16 +00006377 return a list or None rather than a custom object.
6378
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006379- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006403 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6404 for catch_warnings() also led to an improvement in the raising of a
6405 DeprecationWarning related to warnings.warn_explicit().
6406
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006407- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006471What's New in Python 2.6 beta 3?
6472================================
6473
Barry Warsaw07a4a382008-08-21 01:15:08 +00006474*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006475
6476Core and Builtins
6477-----------------
6478
Guido van Rossumf8402962008-08-20 15:01:50 +00006479- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6480 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6481 extensions do not automatically benefit from the class attribute
6482 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6483 to their tp_flags field if they care. This is a backwards
6484 compatibility feature; in 3.0, all types will use the cache by
6485 default.
6486
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006487- Keyword arguments can now follow starred arguments. (``f(a, *args,
6488 keyword=23)`` is now valid syntax.)
6489
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006490- ctypes function pointers that are COM methods have a boolean True
6491 value again.
6492
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006493- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6494 by denying s# to parse objects that have a releasebuffer procedure,
6495 and introducing s*.
6496
Georg Brandl1e13ea92008-08-11 09:07:59 +00006497- Issue #3537: Fix an assertion failure when an empty but presized dict
6498 object was stored in the freelist.
6499
Mark Dickinsonb6467572008-08-04 21:30:09 +00006500- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6501 ValueError consistently across platforms.
6502
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006503- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6504 (64bit Unix, for example), unichr() would truncate its argument and return
6505 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6506
Neal Norwitze7d8be82008-07-31 17:17:14 +00006507- Apply security patches from Apple.
6508
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006509- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6510 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6511
Antoine Pitrou92f82162008-07-25 22:22:08 +00006512- Issue #1819: function calls with several named parameters are now on
6513 average 35% faster (as measured by pybench).
6514
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006515- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6516 the python debugger steps into a class statement: the free variables (local
6517 variables defined in an outer scope) would be deleted from the outer scope.
6518
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006519- Issue #2620: Overflow checking when allocating or reallocating memory
6520 was not always being done properly in some python types and extension
6521 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6522 all been updated to perform better checks and places in the code that
6523 would previously leak memory on the error path when such an allocation
6524 failed have been fixed.

6530
Benjamin Petersone977ad42008-08-20 01:42:01 +00006531- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6532 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6533
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006534- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6535 version reported by these tools does not necessarily follow the python
6536 version numbering scheme, so the module is less strict when parsing it.
6537
Nick Coghlanf70385a2008-08-18 12:42:46 +00006538- Issue #2235: Added Py3k warnings for types which will become unhashable
6539 under the stricter __hash__ inheritance rules in 3.0. Several types
6540 which did not meet the rules for hash invariants and were already
6541 unhashable in 3.0 have now been explicitly flagged as unhashable in
6542 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6543 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6544
Brett Cannon88f801d2008-08-18 00:46:22 +00006545- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6546 imported into the module but exposed as part of the module's API.
6547
Brett Cannon7b96f072008-08-18 00:41:11 +00006548- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006552- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6553
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006554- Issue #3575: Incremental decoder's decode function now takes bytearray
6555 by using 's*' instead of 't#'.
6556
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006557- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006558 fails unicode conversion on 2nd parameter. (windows only)

6658
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006659- Issue #643841: The language reference now provides more detailed

6671-----------------
6672
Georg Brandl3e483f62008-07-16 22:57:41 +00006673- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6674 its methods now allow for items objects that can be converted to
6675 an integer using operator.index().
6676
Mark Dickinson64b7e502008-07-16 09:40:03 +00006677- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6678 produced a ValueError instead of giving the correct float.
6679
Eric Smitha5fa5a22008-07-16 00:11:49 +00006680- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6681 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6682
Mark Dickinson7103aa42008-07-15 19:08:33 +00006683- Issue #3008: the float type has a new instance method 'float.hex'
6684 and a new class method 'float.fromhex' to convert floating-point
6685 numbers to and from hexadecimal strings, respectively.
6686
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006687- Issue #2235: __hash__ is once again inherited by default. To allow
6688 collections.Hashable to remain meaningful in the presence of the
6689 default hash implementation (object.__hash__), it is now possible
6690 to explicit block inheritance of hash by setting __hash__=None at
6691 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6692 level.
6693
Nick Coghlanb028f502008-07-13 14:52:36 +00006694- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6695 the parent module cannot be found while performing an absolute import.
6696 This means that an incorrectly defined __package__ attribute will
6697 now only prevent relative imports in that module rather than causing
6698 all imports from that module to fail.
6699
Nick Coghlan14ff9942008-07-08 14:21:42 +00006700- Issue #2517: Allow unicode messages in Exceptions again by correctly

6710 another thread's dictionary.
6711
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006712- Issue #3004: Minor change to slice.indices(): the start and stop
6713 arguments are now treated identically, making the behaviour easier
6714 to describe and understand. For example, slice(None, -10,
6715 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6716 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6717 10, -1).
6718
Georg Brandl278fc502008-07-19 12:46:12 +00006719- Issue #3219: Calling a function with repeated keyword arguments,
6720 f(a=2, a=23), would not cause a syntax error. This was a regression
6721 from 2.4 caused by the switch to the new compiler.

6732 error when they failed.
6733
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006734- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006759- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6760 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006761 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006762 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006778- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7168
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007169- On MacOS X it is now possible to install the framework in 64-bit
7170 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007171 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007172
7173 This is controlled by the configure argument ``--with-universal-archs``:
7174
7175 - ``--with-universal-archs=all``: install 4-way universal
7176
7177 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7178
7179 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7180
7181 This option should be used in combination with ``--enable-universalsdk=``.
7182
7183 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 +00007233- Issue #1631171: Re-implement the 'warnings' module in C (the
7234 original Python code has been kept as backup). This will allow for
7235 using the 'warning's machinery in such places as the parser where
7236 use of pure Python code is not possible. Both the ``showarning()``
7237 and ``formatwarning()`` gain an optional 'line' argument which is
7238 not called by default for backwards-compatibility reasons. Setting
7239 ``warnings.showwarning()`` to an implementation that lacks support
7240 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007282- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007283 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007303- Issue #2550: The approach used by client/server code for obtaining
7304 ports to listen on in network-oriented tests has been refined in an
7305 effort to facilitate running multiple instances of the entire
7306 regression test suite in parallel without issue.
7307 test_support.bind_port() has been fixed such that it will always
7308 return a unique port -- which wasn't always the case with the
7309 previous implementation, especially if socket options had been set
7310 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7311 new implementation of bind_port() will actually raise an exception
7312 if it is passed an AF_INET/SOCK_STREAM socket with either the
7313 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7314 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7315 the socket it's been passed. This currently only applies to
7316 Windows. This option prevents any other sockets from binding to the
7317 host/port we've bound to, thus removing the possibility of the
7318 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7319 when a second SOCK_STREAM socket binds and accepts to a host/port
7320 that's already been bound by another socket. The optional preferred
7321 port parameter to bind_port() has been removed. Under no
7322 circumstances should tests be hard coding ports!
7323
7324 test_support.find_unused_port() has also been introduced, which will
7325 pass a temporary socket object to bind_port() in order to obtain an
7326 unused port. The temporary socket object is then closed and
7327 deleted, and the port is returned. This method should only be used
7328 for obtaining an unused port in order to pass to an external program
7329 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7330 a parameter to a server-oriented class that doesn't give you direct
7331 access to the underlying socket used.
7332
7333 Finally, test_support.HOST has been introduced, which should be used
7334 for the host argument of any relevant socket calls (i.e. bind and
7335 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007336
7337 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007338 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007339 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7340 test_asynchat and test_socket_ssl.
7341
Georg Brandl3ee81df2008-05-17 18:14:43 +00007342 It is now possible for multiple instances of the regression test
7343 suite to run in parallel without issue.

7401 this case, like normal unicode literals and the 'unicode-escape'

Eric Smitha73fbe72008-02-23 03:09:44 +00007622- Added the future_builtins module, which contains hex() and oct().
7623 These are the PEP 3127 version of these functions, designed to be
7624 compatible with the hex() and oct() builtins from Python 3.0. They
7625 differ slightly in their output formats from the existing, unchanged
7626 Python 2.6 builtins. The expected usage of the future_builtins
7627 module is:
7628 from future_builtins import hex, oct
7629
Eric Smith7ef40bf2008-02-20 23:34:22 +00007630- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7631 exponents for exponents with absolute value < 100. Follows C99
7632 standard. This is a change on Windows, which would use 3 digits.
7633 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7634 so that any alterations it does to the resulting string will be
7635 available in stringlib/formatter.h (for float.__format__).
7636
Eric Smith5a3c1352008-02-19 13:21:56 +00007637- Implemented PEP 3101, Advanced String Formatting. This adds a new
7638 builtin format(); a format() method for str and unicode; a
7639 __format__() method to object, str, unicode, int, long, float, and
7640 datetime; the class string.Formatter; and the C API
7641 PyObject_Format().
7642
Georg Brandl3ee81df2008-05-17 18:14:43 +00007643- Fixed several potential crashes, all caused by specially crafted
7644 __del__ methods exploiting objects in temporarily inconsistent
7645 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007654- Clear all free lists during a gc.collect() of the highest generation
7655 in order to allow pymalloc to free more arenas. Python may give back
7656 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007657
Georg Brandl3ee81df2008-05-17 18:14:43 +00007658- Issue #2045: Fix an infinite recursion triggered when printing a
7659 subclass of collections.defaultdict, if its default_factory is set
7660 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007661
Christian Heimesf75dbef2008-02-08 00:11:31 +00007662- Fixed a minor memory leak in dictobject.c. The content of the free
7663 list was not freed on interpreter shutdown.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007688- Patch #1473257: generator objects gain a gi_code attribute. This is
7689 the same object as the func_code attribute of the function that
7690 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007691
Georg Brandl3ee81df2008-05-17 18:14:43 +00007692- Issue #1920: "while 0" statements were completely removed by the
7693 compiler, even in the presence of an "else" clause, which is
7694 supposed to be run when the condition is false. Now the compiler
7695 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007696
Guido van Rossumeead05f2008-01-24 18:21:02 +00007697- A few crashers fixed: weakref_in_del.py (issue #1377858);
7698 loosing_dict_ref.py (issue #1303614, test67.py);
7699 borrowed_ref_[34].py (not in tracker).

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007701- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007702 suppressed while an extension is loaded by calling SetErrorMode in

7704
Georg Brandl3ee81df2008-05-17 18:14:43 +00007705- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007706 several extension methods and modules do not work without unicode
7707 support.
7708
Georg Brandl26543b12008-01-21 18:36:51 +00007709- Issue #1882: when compiling code from a string, encoding cookies in the

7713
Georg Brandl6caad7d2008-01-26 14:19:22 +00007714- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007715 added.
7716
Christian Heimesc94e2b52008-01-14 04:13:37 +00007717- sys.float_info / PyFloat_GetInfo: The floating point information
7718 object was converted from a dict to a specialized structseq object.
7719
Georg Brandl3ee81df2008-05-17 18:14:43 +00007720- Patch #1816: Added sys.flags structseq. It exposes the status of
7721 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007722
Georg Brandl3ee81df2008-05-17 18:14:43 +00007723- Objects/structseq.c: Implemented new structseq representation. The
7724 patch makes structseqs (e.g. the return value of os.stat) more
7725 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007726
Georg Brandl3ee81df2008-05-17 18:14:43 +00007727- Patch #1700288: added a type attribute cache that caches method
7728 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007729
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007730- Bug #1776: __import__() no longer accepts filenames on any platform.

Georg Brandlaed6c662008-01-07 17:25:53 +00007733- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7734
Georg Brandl3ee81df2008-05-17 18:14:43 +00007735- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7736 envvar and sys.dont_write_bytecode attribute. All these can be set
7737 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007738
Georg Brandl3ee81df2008-05-17 18:14:43 +00007739- Improve some exception messages when Windows fails to load an
7740 extension module. Now we get for example '%1 is not a valid Win32
7741 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007748- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007749 and INF. float("nan"), float("inf") and float("-inf") now work on
7750 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007751
Georg Brandl3ee81df2008-05-17 18:14:43 +00007752- Compiler now generates simpler and faster code for dictionary
7753 literals. The oparg for BUILD_MAP now indicates an estimated
7754 dictionary size. There is a new opcode, STORE_MAP, for adding
7755 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007784- Patch #1739468: Directories and zipfiles containing a __main__.py
7785 file can now be directly executed by passing their name to the
7786 interpreter. The directory/zipfile is automatically inserted as the
7787 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007789- Issue #1265: Fix a problem with sys.settrace, if the tracing
7790 function uses a generator expression when at the same time the
7791 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007792
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007793- sets and frozensets now have an isdisjoint() method.
7794
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007795- optimize the performance of builtin.sum().

7798
Georg Brandl21e99f42010-03-07 15:23:59 +00007799- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007800 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7801 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007802
Georg Brandl3ee81df2008-05-17 18:14:43 +00007803- Issue #1686386: Tuple's tp_repr did not take into account the
7804 possibility of having a self-referential tuple, which is possible
7805 from C code. Nor did object's tp_str consider that a type's tp_str
7806 could do something that could lead to an inifinite recursion.
7807 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7808 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007809
Georg Brandl3ee81df2008-05-17 18:14:43 +00007810- Issue #1164: It was possible to trigger deadlock when using the
7811 'print' statement to write to a file since the GIL was not released
7812 as needed. Now PyObject_Print() does the right thing along with
7813 various tp_print implementations of the built-in types and those in
7814 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007815
Georg Brandl3ee81df2008-05-17 18:14:43 +00007816- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00007823- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007824 PyObject_Call() never calling back out to Python code to trigger
7825 recursion depth updates/checks. Required the creation of a static
7826 RuntimeError instance in case normalizing an exception put the
7827 recursion check value past its limit. Fixes crashers
7828 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007843- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007844 __*__ attributes. (Some already existed, e.g., __doc__ and
7845 __name__.)

7849
Georg Brandl2134e752007-05-21 20:34:16 +00007850- Patch #1686487: you can now pass any mapping after '**' in function
7851 calls.
7852
Collin Winter62903052007-05-18 23:11:24 +00007853- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007854 "except E as target:". This is to provide forwards compatibility
7855 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007862- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007863 setting a plain string, ie don't expand to single letter identifiers.
7864
Raymond Hettinger13936692007-04-11 18:40:58 +00007865- Request #1191699: Slices can now be pickled.
7866
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007867- Request #1193128: str.translate() now allows a None argument for

7869 remaining characters.
7870
Georg Brandl5cb76c12007-03-21 09:00:39 +00007871- Patch #1682205: a TypeError while unpacking an iterable is no longer

7875
Guido van Rossum143b5642007-03-23 04:58:42 +00007876- Bug #1683368: The object.__init__() and object.__new__() methods are
7877 now stricter in rejecting excess arguments. The only time when
7878 either allows excess arguments is when it is not overridden and the
7879 other one is. For backwards compatibility, when both are
7880 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007881 warning later). Also, type.__init__() insists on the same signature
7882 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007884- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7885 object to complex using its __complex__() method before falling back
7886 to the __float__() method. Therefore, the functions in the cmath
7887 module now can operate on objects that define a __complex__()
7888 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007910 its argument, if it exists. If not, it will work like before. This
7911 allows customizing the output of dir() in the presence of a
7912 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00007924- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00007994- Bug #1545497: when given an explicit base, int() did ignore NULs
7995 embedded in the string to convert.
7996
Georg Brandl846f73a2006-10-08 07:11:54 +00007997- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00008045 generator expressions (x for x, in ... ) works again. Fixing this
8046 problem required changing the .pyc magic number. This means that
8047 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008956 time so that opening a database previously created with the DB_DUP
8957 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8958 opens. Specifically: dictionary assignment to a DB object will
8959 replace all values for a given key when the database allows
8960 duplicate values. DB users should use DB.put(k, v) when they want
8961 to store duplicates; not DB[k] = v.

8968 characters with ASCII value less than 32. Also, it correctly quotes
8969 dots only if they occur on a single line, as opposed to the previous
8970 behavior of quoting dots if they are the second character of any
8971 line.
