1632 32-bit-only installer Pythons on systems with Xcode 4 (currently
1633 OS X 10.8, 10.7, and optionally 10.6).
1634 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1635 * Since Xcode 4 removes ppc support, extension module builds now
1636 check for ppc compiler support and by default remove ppc and
1637 ppc64 archs when they are not available.
1638 * Extension module builds now revert to using system installed
1639 headers and libs (/usr and /System/Library) if the SDK used
1640 to build the interpreter is not installed or has moved.
1641 * Try to avoid building extension modules with deprecated
1642 and problematic Apple llvm-gcc compiler. If original compiler
1643 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002067- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002068 has left two versions of customize_compiler, the original in
2069 distutils.sysconfig and another copy in distutils.ccompiler, with some
2070 parts of distutils calling one and others using the other.
2071 Complete the revert back to only having one in distutils.sysconfig as
2072 is the case in 3.x.
2073
Ned Deily0d0ea482012-02-10 12:59:06 +01002074- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2075 Distutils-based packages with C extension modules may fail because
2076 Apple has removed gcc-4.2, the version used to build python.org
2077 64-bit/32-bit Pythons. If the user does not explicitly override
2078 the default C compiler by setting the CC environment variable,
2079 Distutils will now attempt to compile extension modules with clang
2080 if gcc-4.2 is required but not found. Also as a convenience, if
2081 the user does explicitly set CC, substitute its value as the default
2082 compiler in the Distutils LDSHARED configuration variable for OS X.
2083 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2084 SDK, neither of which are available in Xcode 4. This change does not
2085 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002335- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2336 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2337 interpreter process. This could cause failures in non-Distutils subprocesses
2338 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002339 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002340 deployment target only in the environment of each build subprocess. It is
2341 still possible to globally override the default by setting
2342 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2343 greater or equal to the default value, the value with which the interpreter
2344 was built.

2374 the ticker doesn't have to wind down to zero from the old starting point
2375 before the new interval takes effect. And if the user increases the
2376 interval, it makes sure the new limit takes effect right away rather have an
2377 early task switch before recognizing the new interval.

3818-----------------
3819
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003820- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3821 start byte and the continuation byte(s) are now considered invalid, instead
3822 of the number of bytes specified by the start byte.
3823 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3824 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3825 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3826 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003828- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003829 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3830 arises from the "Overriding __eq__ blocks inheritance ..." warning
3831 when turned into an exception: in this case the exception simply
3832 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003833
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003834- Issue #8748: Fix two issues with comparisons between complex and integer
3835 objects. (1) The comparison could incorrectly return True in some cases
3836 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3837 (2) The comparison raised an OverflowError for large integers, leading
3838 to unpredictable exceptions when combining integers and complex objects
3839 in sets or dicts.
3840
Mark Dickinson81336372010-05-30 12:12:25 +00003841- Issue #5211: Implicit coercion for the complex type is now completely
3842 removed. (Coercion for arithmetic operations was already removed in 2.7
3843 alpha 4, but coercion for rich comparisons was accidentally left in.)
3844
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003845- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00004032- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4033 operation raises multiple signals and more than one of those signals is
4034 trapped, the specification determines the order in which the signals should be
4035 handled. In many cases this order wasn't being followed, leading to the wrong
4036 Python exception being raised.

4222 with a non-empty format string. This is an effort to future-proof user
4223 code. If a derived class does not currently implement __format__ but later
4224 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004225 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004226 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004276- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4277 InvalidOperation instead of returning False. (Comparisons involving a quiet
4278 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4279 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004281- Issue #2531: Comparison operations between floats and Decimal instances now
4282 return a result based on the numeric values of the operands; previously they
4283 returned an arbitrary result based on the relative ordering of id(float) and
4284 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004286- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004287 argument `-` which tells it to read files to compile from stdin. Each line is
4288 read on demand and the named file is compiled immediately. (Original patch by
4289 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00004298- Comparisons using one of <, <=, >, >= between a complex instance and a
4299 Fractions instance now raise TypeError instead of returning True/False. This
4300 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4301 <=> complex, and complex <=> complex comparisons.

4401 integer format code, struct.pack first attempts to convert the non-integer

4404
Georg Brandlba83f822010-03-14 09:50:54 +00004405- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4406 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4407 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004408 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4409 inconsistent: __int__ was used for some integer codes but not for others, and
4410 the set of integer codes for which it was used differed between native packing
4411 and standard packing.)

4720 position to the given argument, which goes against the tradition of

4724 class used to represent files stored inside an archive. The new
4725 implementation is significantly faster and can be wrapped in a

4816-----------------
4817
Georg Brandlba83f822010-03-14 09:50:54 +00004818- The ``__complex__()`` method is now looked up on the class of instances to
4819 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004821- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4822 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4823
Mark Dickinson1b34d252010-01-01 17:27:30 +00004824- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004825 DeprecationWarning when passed a float argument where an integer was expected.
4826 These functions and methods now raise TypeError instead. The majority of the
4827 effects of this change are in the extension modules, but some core functions
4828 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4829 and many unicode/str methods.

4841
Georg Brandlba83f822010-03-14 09:50:54 +00004842- Issue #1811: Improve accuracy and cross-platform consistency for true division
4843 of integers: the result of a/b is now correctly rounded for ints a and b (at
4844 least on IEEE 754 platforms), and in particular does not depend on the
4845 internal representation of a long.

4853
Georg Brandlba83f822010-03-14 09:50:54 +00004854 These executables now work properly with the arch(1) command: ``arch -ppc
4855 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004993- Issue #3382: 'F' formatting for float and complex now convert the result to
4994 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4995 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004996
Georg Brandlba83f822010-03-14 09:50:54 +00004997- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4998 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004999
Georg Brandlba83f822010-03-14 09:50:54 +00005000- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5001 1e-100 used to raise OverflowError, but now gives the requested 120
5002 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00005003
Georg Brandlba83f822010-03-14 09:50:54 +00005004- Add Py3k warnings for parameter names in parentheses.

5009 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005010
Georg Brandlba83f822010-03-14 09:50:54 +00005011- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5012 decimal string that's guaranteed to round back to x under correct rounding
5013 (with round-half-to-even rounding mode). Previously it gave a string based on
5014 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5015 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5016 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005017
Georg Brandlba83f822010-03-14 09:50:54 +00005018- Issue #7117: On almost all platforms: float-to-string and string-to-float
5019 conversions within Python are now correctly rounded. Places these conversions
5020 occur include: str for floats and complex numbers; the float and complex
5021 constructors; old-style and new-style numeric formatting; serialization and
5022 deserialization of floats and complex numbers using marshal, pickle and json;
5023 parsing of float and imaginary literals in Python code; Decimal-to-float
5024 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005025
Georg Brandlba83f822010-03-14 09:50:54 +00005026 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5027 providing correctly-rounded strtod and dtoa C functions. This code is
5028 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5029 the C compiler. There may be a small number of platforms on which correct
5030 operation of this code cannot be guaranteed, so the code is not used: notably,
5031 this applies to platforms where the C double format is not IEEE 754 binary64,
5032 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5033 and Python's configure script is unable to determine how to change the FPU
5034 precision. On these platforms conversions use the platform strtod and dtoa,
5035 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005036
Georg Brandlba83f822010-03-14 09:50:54 +00005037- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5038 uses the correctly-rounded string <-> float conversions described above (when
5039 available), and so produces correctly rounded results that will display nicely
5040 under the float repr. There are two related small changes: (1) round now
5041 accepts any class with an ``__index__()`` method for its second argument (but
5042 no longer accepts floats for the second argument), and (2) an excessively
5043 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5044 raises an exception.

5047
Georg Brandlba83f822010-03-14 09:50:54 +00005048- Fix several issues with ``compile()``. The input can now contain Windows and

5193 but with at least one decimal point and with a default precision
5194 of 12. Previously, the behavior the same but with a default precision of 6.
5195 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00005206- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
5207 '.5')`` now produces a sensible result.
Eric Smith9139cc62009-04-30 00:58:58 +00005208
Georg Brandlba83f822010-03-14 09:50:54 +00005209- Issue #5864: Fix empty format code formatting for floats so that it never
5210 gives more than the requested number of significant digits.
Mark Dickinson92fcc9c2009-04-29 20:41:00 +00005211
Georg Brandlba83f822010-03-14 09:50:54 +00005212- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new

5216 not their own uppercase.
Martin v. Löwis99f27792009-04-26 00:53:18 +00005217
Eric Smith068f0652009-04-25 21:40:15 +00005218- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
5219 _PyOS_double_to_string or PyOS_double_to_string.
5220
Benjamin Peterson5083dc52009-04-25 00:41:22 +00005221- Issue #5283: Setting __class__ in __del__ caused a segfault.
5222
Georg Brandlba83f822010-03-14 09:50:54 +00005223- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
5224 nans, infs or negative zeros.

Georg Brandlba83f822010-03-14 09:50:54 +00005232- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
5233 type code and we have an exponent.
Eric Smithaca19e62009-04-22 13:29:05 +00005234
Georg Brandlba83f822010-03-14 09:50:54 +00005235- Issue #3166: Make long -> float (and int -> float) conversions correctly

Georg Brandlba83f822010-03-14 09:50:54 +00005241- Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was
5242 giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005261- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005262 untrackable objects are not tracked by the garbage collector. This can reduce
5263 the size of collections and therefore the garbage collection overhead on
5264 long-running programs, depending on their particular use of datatypes.
Antoine Pitrouf8387af2009-03-23 18:41:45 +00005265
Georg Brandlba83f822010-03-14 09:50:54 +00005266- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its

5268 150% faster.
Mark Dickinson0b666bf2009-03-23 18:25:13 +00005269
Georg Brandlba83f822010-03-14 09:50:54 +00005270- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
5271 internal representation of integers, for performance reasons. Base 2**30 is
5272 enabled by default on 64-bit machines. Add --enable-big-digits option to
5273 configure, which overrides the default. Add sys.long_info structseq to
5274 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00005275
Benjamin Peterson6ffe8522009-03-18 20:52:15 +00005276- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
5277 result traceback.__members__ no longer exists.)
5278
Georg Brandlba83f822010-03-14 09:50:54 +00005279- Issue #4474: PyUnicode_FromWideChar now converts characters outside the BMP to
5280 surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE)
5281 == 2.
Mark Dickinson6b265f12009-03-18 16:07:26 +00005282
Georg Brandlba83f822010-03-14 09:50:54 +00005283- Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{}
5284 {}'.format(1, 2) == '1 2'``.
Eric Smith6f42edb2009-03-14 11:57:26 +00005285
Georg Brandlba83f822010-03-14 09:50:54 +00005286- Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a
Brett Cannon6c4cff02009-03-11 04:51:06 +00005287 requirement. Means the DeprecationWarning from Python 2.6 can go away.
5288
Georg Brandlba83f822010-03-14 09:50:54 +00005289- Issue #5247: Improve error message when unknown format codes are used when
5290 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00005291
Georg Brandlba83f822010-03-14 09:50:54 +00005292- Running Python with the -3 option now also warns about classic division for
5293 ints and longs.
Raymond Hettinger08259e82009-02-18 23:10:19 +00005294
Georg Brandlba83f822010-03-14 09:50:54 +00005295- Issue #5260: Long integers now consume less memory: average saving is 2 bytes
5296 per long on a 32-bit system and 6 bytes per long on a 64-bit system.
Mark Dickinson2ffb26f2009-02-15 10:13:41 +00005297
Antoine Pitrou76a4b892009-02-13 13:52:33 +00005298- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5299 rotating the object pointer by 4 bits to the right.
5300
Georg Brandlba83f822010-03-14 09:50:54 +00005301- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now
5302 forces its argument to double before testing for infinity.
Mark Dickinsonc97c9092009-02-09 14:18:43 +00005303
Benjamin Petersone18ef192009-01-20 14:21:16 +00005304- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
5305
Georg Brandl29c6a282009-04-05 20:23:13 +00005306- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00005307 were suppressing all exceptions. These include list(), filter(), map(),
5308 zip(), and bytearray().
5309
Benjamin Peterson596d3062009-01-19 15:42:23 +00005310- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
5311 functions.
5312
Benjamin Peterson5848d1f2009-01-19 00:08:08 +00005313- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
5314 OSError.
5315
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +00005316- Issue #4807: Port the _winreg module to Windows CE.
5317
Georg Brandlba83f822010-03-14 09:50:54 +00005318- Issue #4935: The overflow checking code in the expandtabs() method common to
5319 str, bytes and bytearray could be optimized away by the compiler, letting the
5320 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00005321
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00005322- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5323 __next__ method.
5324

5328
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00005329- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5330 collecting the oldest generation) so that allocating lots of objects without
5331 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00005332 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00005333 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

5336
Georg Brandlba83f822010-03-14 09:50:54 +00005337- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5338 existing .py counterpart, override the co_filename attributes of all code
5339 objects if the original filename is obsolete (which can happen if the file has
5340 been renamed, moved, or if it is accessed through different paths). Patch by
5341 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00005342
Georg Brandlba83f822010-03-14 09:50:54 +00005343- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00005345- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
5346 file with `str' filename on Windows.
5347
Antoine Pitrouaa687902009-01-01 14:11:22 +00005348- Issue #3680: Reference cycles created through a dict, set or deque iterator
5349 did not get collected.
5350
Georg Brandlba83f822010-03-14 09:50:54 +00005351- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
5352 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00005353
Benjamin Peterson7af65562008-12-29 17:56:58 +00005354- Issue #4764: With io.open, IOError.filename is set when trying to open a
5355 directory on POSIX systems.
5356
Benjamin Petersonfe231b02008-12-29 17:47:42 +00005357- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
5358 systems.
5359
Georg Brandl6425a2f2008-12-28 11:54:53 +00005360- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00005361 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00005362
Skip Montanarof205c132008-12-23 03:30:15 +00005363- Added test case to ensure attempts to read from a file opened for writing
5364 fail.
5365
Georg Brandlba83f822010-03-14 09:50:54 +00005366- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
5367 elapsed times, not only when some objects are uncollectable/unreachable.
5368 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00005369

Georg Brandlba83f822010-03-14 09:50:54 +00005380- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5381 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5382 instances. On a typical machine this saves 3 bytes of memory (on average) per
5383 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00005384
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005385- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5386 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5387 instead of throwing a MemoryError.
5388
Georg Brandlba83f822010-03-14 09:50:54 +00005389- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5390 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005391
Benjamin Petersonc078f922008-11-21 22:27:24 +00005392- Issue #4367: Python would segfault during compiling when the unicodedata
5393 module couldn't be imported and \N escapes were present.
5394
Georg Brandlba83f822010-03-14 09:50:54 +00005395- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5396 file objects with closefd=False. The file descriptor is still kept open but
5397 the file object behaves like a closed file. The ``FileIO`` object also got a
5398 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005399
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005400- Issue #4348: Some bytearray methods returned that didn't cause any change to
5401 the bytearray, returned the same bytearray instead of a copy.
5402
Georg Brandlba83f822010-03-14 09:50:54 +00005403- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

5406
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005407- Issue #4048: The parser module now correctly validates relative imports.
5408
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005409- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

Benjamin Petersonbdca9422008-10-26 20:21:13 +00005415- Issue #4209: Enabling unicode_literals and the print_function in the same
5416 __future__ import didn't work.
5417
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005418- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005419 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005420
Georg Brandlba83f822010-03-14 09:50:54 +00005421- On windows, ``os.chdir()`` given unicode was not working if
5422 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5423 this code path is really executed because I cannot move to such directory on
5424 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005425
Georg Brandlba83f822010-03-14 09:50:54 +00005426- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5427 element is temporarily replaced with an equivalent frozenset. But the
5428 eventual KeyError would always report the empty ``frozenset()`` as the missing
5429 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00005430

6826-----------------
6827
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006828- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6829
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006830- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6831 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6832 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6833 ``printf`` function, whereas PyString_FromFormat has an independent
6834 implementation and uses "%zd" on all platforms for size_t values.
6835 This makes a difference on win64, where ``printf`` needs "%Id" to display
6836 64bit values.
6837
Benjamin Peterson97179b02008-09-09 20:55:01 +00006838- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6839 error.
6840
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006841- Issue #3777: long() applied to a float object now always return a long
6842 object; previously an int would be returned for small values. the __long__
6843 method is allowed to return either an int or a long, but the behaviour of
6844 float objects should not change to respect backward compatibility.
6845
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006846- Issue #3751: str.rpartition would perform a left-partition when called with
6847 a unicode argument.
6848
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006849- Issue #3683: Fix compilation when --without-threads is given.
6850
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006851- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006852 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006853 was correctly parsed but parsing of subsequent arguments failed.
6854
Vinay Sajip35e3b032008-09-01 14:33:59 +00006855- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006856 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6857 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6858 when given a tuple of classes as second argument, were looking up
6859 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6860 type object.
6861
Neal Norwitz18aa3882008-08-24 05:04:52 +00006862- Fix crashes on memory allocation failure found with failmalloc.
6863
6864- Fix memory leaks found with valgrind and update suppressions file.
6865
6866- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6867
6868- Fix problem using wrong name in decimal module reported by pychecker.
6869
Christian Heimes7d4c3172008-08-22 19:47:25 +00006870- Silenced another compiler warning about a used but not defined
6871 function 'stringlib_contains_obj'.
6872
Benjamin Peterson712ee922008-08-24 18:10:20 +00006873- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6874 ``__delslice__``.
6875
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006876- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6877 library targets in the Makefile.
6878
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006879- Issue #1204: The configure script now tests for additional libraries
6880 that may be required when linking against readline. This fixes issues
6881 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
6882
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00006883C-API

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00006891- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
6892 stack usage in the case of deeply nested objects.
6893

Nick Coghland2e09382008-09-11 12:11:06 +00006904- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00006905 return a list or None rather than a custom object.
6906
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006907- Issue #1638033: Cookie.Morsel gained the httponly attribute.
6908
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00006909- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006931 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6932 for catch_warnings() also led to an improvement in the raising of a
6933 DeprecationWarning related to warnings.warn_explicit().
6934
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006935- The deprecation warnings for the old camelCase threading API were removed.

6957
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006958- Issue #2975: When compiling several extension modules with Visual Studio 2008
6959 from the same python interpreter, some environment variables would grow
6960 without limit.
6961
Benjamin Peterson37346b22008-08-23 20:27:43 +00006962- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6963 exploitation of poor argument checking.
6964
Gerhard Häringef2276b2008-09-12 13:54:06 +00006965- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006999What's New in Python 2.6 beta 3?
7000================================

Barry Warsaw07a4a382008-08-21 01:15:08 +00007002*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007003
7004Core and Builtins
7005-----------------
7006
Guido van Rossumf8402962008-08-20 15:01:50 +00007007- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7008 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7009 extensions do not automatically benefit from the class attribute
7010 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7011 to their tp_flags field if they care. This is a backwards
7012 compatibility feature; in 3.0, all types will use the cache by
7013 default.
7014
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007015- Keyword arguments can now follow starred arguments. (``f(a, *args,
7016 keyword=23)`` is now valid syntax.)
7017
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007018- ctypes function pointers that are COM methods have a boolean True
7019 value again.
7020
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007021- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7022 by denying s# to parse objects that have a releasebuffer procedure,
7023 and introducing s*.
7024
Georg Brandl1e13ea92008-08-11 09:07:59 +00007025- Issue #3537: Fix an assertion failure when an empty but presized dict
7026 object was stored in the freelist.
7027
Mark Dickinsonb6467572008-08-04 21:30:09 +00007028- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7029 ValueError consistently across platforms.
7030
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007031- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7032 (64bit Unix, for example), unichr() would truncate its argument and return
7033 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7034
Neal Norwitze7d8be82008-07-31 17:17:14 +00007035- Apply security patches from Apple.
7036
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007037- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7038 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7039
Antoine Pitrou92f82162008-07-25 22:22:08 +00007040- Issue #1819: function calls with several named parameters are now on
7041 average 35% faster (as measured by pybench).
7042
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007043- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7044 the python debugger steps into a class statement: the free variables (local
7045 variables defined in an outer scope) would be deleted from the outer scope.
7046
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007047- Issue #2620: Overflow checking when allocating or reallocating memory
7048 was not always being done properly in some python types and extension
7049 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7050 all been updated to perform better checks and places in the code that
7051 would previously leak memory on the error path when such an allocation
7052 failed have been fixed.

7055-------
7056
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007057- Issue #3612: Added some missing basic types in ctypes.wintypes.
7058
Benjamin Petersone977ad42008-08-20 01:42:01 +00007059- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7060 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7061
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007062- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7063 version reported by these tools does not necessarily follow the python
7064 version numbering scheme, so the module is less strict when parsing it.
7065
Nick Coghlanf70385a2008-08-18 12:42:46 +00007066- Issue #2235: Added Py3k warnings for types which will become unhashable
7067 under the stricter __hash__ inheritance rules in 3.0. Several types
7068 which did not meet the rules for hash invariants and were already
7069 unhashable in 3.0 have now been explicitly flagged as unhashable in
7070 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7071 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7072
Brett Cannon88f801d2008-08-18 00:46:22 +00007073- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7074 imported into the module but exposed as part of the module's API.
7075
Brett Cannon7b96f072008-08-18 00:41:11 +00007076- Remove an unneeded import of abc.ABCMeta from 'inspect'.

7081
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007082- Issue #3575: Incremental decoder's decode function now takes bytearray
7083 by using 's*' instead of 't#'.
7084
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007085- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007086 fails unicode conversion on 2nd parameter. (windows only)
7087
Georg Brandl222e2082010-08-01 22:27:39 +00007088- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007089 in a redirect.
7090
Brett Cannonabe423e2008-08-16 21:47:07 +00007091- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007092 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007093
Facundo Batistaeb90b782008-08-16 14:44:07 +00007094- Issue #2776: fixed small issue when handling an URL with double slash
7095 after a 302 response in the case of not going through a proxy.
7096
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007097- Issue #2676: in the email package, content-type parsing was hanging on
7098 pathological input because of quadratic or exponential behaviour of a
7099 regular expression.
7100
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007101- Issue #3476: binary buffered reading through the new "io" library is now
7102 thread-safe.
7103
Brett Cannonbf3157b2008-08-14 05:00:03 +00007104- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7105 since mimetools itself is deprecated. Because modules are cached, all
7106 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7107

Antoine Pitroude781a42008-08-09 12:43:23 +00007142 asking for a specific length. This problem only affected files opened

7186
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007187- Issue #643841: The language reference now provides more detailed

7200
Georg Brandl3e483f62008-07-16 22:57:41 +00007201- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7202 its methods now allow for items objects that can be converted to
7203 an integer using operator.index().
7204
Mark Dickinson64b7e502008-07-16 09:40:03 +00007205- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7206 produced a ValueError instead of giving the correct float.
7207
Eric Smitha5fa5a22008-07-16 00:11:49 +00007208- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7209 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7210
Mark Dickinson7103aa42008-07-15 19:08:33 +00007211- Issue #3008: the float type has a new instance method 'float.hex'
7212 and a new class method 'float.fromhex' to convert floating-point
7213 numbers to and from hexadecimal strings, respectively.
7214
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007215- Issue #2235: __hash__ is once again inherited by default. To allow
7216 collections.Hashable to remain meaningful in the presence of the
7217 default hash implementation (object.__hash__), it is now possible
7218 to explicit block inheritance of hash by setting __hash__=None at
7219 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7220 level.
7221
Nick Coghlanb028f502008-07-13 14:52:36 +00007222- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7223 the parent module cannot be found while performing an absolute import.
7224 This means that an incorrectly defined __package__ attribute will
7225 now only prevent relative imports in that module rather than causing
7226 all imports from that module to fail.
7227
Nick Coghlan14ff9942008-07-08 14:21:42 +00007228- Issue #2517: Allow unicode messages in Exceptions again by correctly

7238 another thread's dictionary.
7239
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007240- Issue #3004: Minor change to slice.indices(): the start and stop
7241 arguments are now treated identically, making the behaviour easier
7242 to describe and understand. For example, slice(None, -10,
7243 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7244 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7245 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007247- Issue #3219: Calling a function with repeated keyword arguments,

7249 from 2.4 caused by the switch to the new compiler.

7288 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007289 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007290 content-length. The problem had been corrected in the 2.4 branch, but never

Benjamin Peterson23681932008-05-12 21:42:13 +00007674
Vinay Sajip9828b7e2008-06-17 11:04:02 +00007675- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007676 environment to control the '-arch' flags that are used to build
7677 an extension. This was added for compatibility with Apple's build
7678 of Python.
7679
7680- The bundled OSX-specific copy of libbffi is now in sync with the version
7681 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
7682
Georg Brandl25c34082008-08-18 23:09:49 +00007683- The threading module gained aliases for names that will be removed in the
7684 3.x series.

7692
Brett Cannonb61d8012008-05-11 23:39:04 +00007693- ``Lib/lib-old`` is now added to sys.path.
7694
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007695- On MacOS X it is now possible to install the framework in 64-bit
7696 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007697 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007698
7699 This is controlled by the configure argument ``--with-universal-archs``:
7700
7701 - ``--with-universal-archs=all``: install 4-way universal
7702
7703 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7704
7705 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7706
7707 This option should be used in combination with ``--enable-universalsdk=``.
7708
7709 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00007717
7718- The PyString functions have been renamed to PyBytes. A batch of
7719 defines were added so that the linker still sees the original
7720 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007758- Issue #1631171: Re-implement the 'warnings' module in C (the
7759 original Python code has been kept as backup). This will allow for
7760 using the 'warning's machinery in such places as the parser where
7761 use of pure Python code is not possible. Both the ``showarning()``
7762 and ``formatwarning()`` gain an optional 'line' argument which is
7763 not called by default for backwards-compatibility reasons. Setting
7764 ``warnings.showwarning()`` to an implementation that lacks support
7765 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007790- The getpass module has been improved on Unix. It now uses /dev/tty
7791 by default and uses stderr instead of stdout. A GetPassWarning is
7792 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007807- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007808 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007828- Issue #2550: The approach used by client/server code for obtaining
7829 ports to listen on in network-oriented tests has been refined in an
7830 effort to facilitate running multiple instances of the entire
7831 regression test suite in parallel without issue.
7832 test_support.bind_port() has been fixed such that it will always
7833 return a unique port -- which wasn't always the case with the
7834 previous implementation, especially if socket options had been set
7835 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7836 new implementation of bind_port() will actually raise an exception
7837 if it is passed an AF_INET/SOCK_STREAM socket with either the
7838 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7839 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7840 the socket it's been passed. This currently only applies to
7841 Windows. This option prevents any other sockets from binding to the
7842 host/port we've bound to, thus removing the possibility of the
7843 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7844 when a second SOCK_STREAM socket binds and accepts to a host/port
7845 that's already been bound by another socket. The optional preferred
7846 port parameter to bind_port() has been removed. Under no
7847 circumstances should tests be hard coding ports!
7848
7849 test_support.find_unused_port() has also been introduced, which will
7850 pass a temporary socket object to bind_port() in order to obtain an
7851 unused port. The temporary socket object is then closed and
7852 deleted, and the port is returned. This method should only be used
7853 for obtaining an unused port in order to pass to an external program
7854 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7855 a parameter to a server-oriented class that doesn't give you direct
7856 access to the underlying socket used.
7857
7858 Finally, test_support.HOST has been introduced, which should be used
7859 for the host argument of any relevant socket calls (i.e. bind and
7860 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007861
7862 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007863 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007864 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7865 test_asynchat and test_socket_ssl.
7866
Georg Brandl3ee81df2008-05-17 18:14:43 +00007867 It is now possible for multiple instances of the regression test
7868 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008147- Added the future_builtins module, which contains hex() and oct().
8148 These are the PEP 3127 version of these functions, designed to be
8149 compatible with the hex() and oct() builtins from Python 3.0. They
8150 differ slightly in their output formats from the existing, unchanged
8151 Python 2.6 builtins. The expected usage of the future_builtins
8152 module is:
8153 from future_builtins import hex, oct
8154
Eric Smith7ef40bf2008-02-20 23:34:22 +00008155- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8156 exponents for exponents with absolute value < 100. Follows C99
8157 standard. This is a change on Windows, which would use 3 digits.
8158 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8159 so that any alterations it does to the resulting string will be
8160 available in stringlib/formatter.h (for float.__format__).
8161
Eric Smith5a3c1352008-02-19 13:21:56 +00008162- Implemented PEP 3101, Advanced String Formatting. This adds a new
8163 builtin format(); a format() method for str and unicode; a
8164 __format__() method to object, str, unicode, int, long, float, and
8165 datetime; the class string.Formatter; and the C API
8166 PyObject_Format().
8167
Georg Brandl3ee81df2008-05-17 18:14:43 +00008168- Fixed several potential crashes, all caused by specially crafted
8169 __del__ methods exploiting objects in temporarily inconsistent
8170 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00008172- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008173 prevent a possible crash: an Abstract Base Class would try to access
8174 a slot on a registered virtual subclass.

8181 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008182
Georg Brandl3ee81df2008-05-17 18:14:43 +00008183- Issue #2045: Fix an infinite recursion triggered when printing a
8184 subclass of collections.defaultdict, if its default_factory is set
8185 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008186
Christian Heimesf75dbef2008-02-08 00:11:31 +00008187- Fixed a minor memory leak in dictobject.c. The content of the free
8188 list was not freed on interpreter shutdown.
8189
Georg Brandl21e99f42010-03-07 15:23:59 +00008190- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008191 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008192
Georg Brandl3ee81df2008-05-17 18:14:43 +00008193- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8194 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008195 to compact the internal free lists of pre-allocted ints and floats.
8196
Georg Brandl3ee81df2008-05-17 18:14:43 +00008197- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8198 calls. Python expected the return type int but the fork familie
8199 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008200
Georg Brandl3ee81df2008-05-17 18:14:43 +00008201- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8202 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008203
Georg Brandl3ee81df2008-05-17 18:14:43 +00008204- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8205 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008206
Georg Brandl3ee81df2008-05-17 18:14:43 +00008207- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8208 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00008210- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8211 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008212
Georg Brandl3ee81df2008-05-17 18:14:43 +00008213- Patch #1473257: generator objects gain a gi_code attribute. This is
8214 the same object as the func_code attribute of the function that
8215 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008216
Georg Brandl3ee81df2008-05-17 18:14:43 +00008217- Issue #1920: "while 0" statements were completely removed by the
8218 compiler, even in the presence of an "else" clause, which is
8219 supposed to be run when the condition is false. Now the compiler
8220 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008221
Guido van Rossumeead05f2008-01-24 18:21:02 +00008222- A few crashers fixed: weakref_in_del.py (issue #1377858);
8223 loosing_dict_ref.py (issue #1303614, test67.py);
8224 borrowed_ref_[34].py (not in tracker).
8225
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008226- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008227 suppressed while an extension is loaded by calling SetErrorMode in
8228 dynload_win.c. The error is still reported properly.
8229
Georg Brandl3ee81df2008-05-17 18:14:43 +00008230- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008231 several extension methods and modules do not work without unicode
8232 support.
8233
Georg Brandl26543b12008-01-21 18:36:51 +00008234- Issue #1882: when compiling code from a string, encoding cookies in the
8235 second line of code were not always recognized correctly.
8236
Georg Brandl14404b62008-01-19 19:27:05 +00008237- Issue #1679: "0x" was taken as a valid integer literal.
8238
Georg Brandl6caad7d2008-01-26 14:19:22 +00008239- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008240 added.
8241
Christian Heimesc94e2b52008-01-14 04:13:37 +00008242- sys.float_info / PyFloat_GetInfo: The floating point information
8243 object was converted from a dict to a specialized structseq object.
8244
Georg Brandl3ee81df2008-05-17 18:14:43 +00008245- Patch #1816: Added sys.flags structseq. It exposes the status of
8246 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008247
Georg Brandl3ee81df2008-05-17 18:14:43 +00008248- Objects/structseq.c: Implemented new structseq representation. The
8249 patch makes structseqs (e.g. the return value of os.stat) more
8250 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008251
Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- Patch #1700288: added a type attribute cache that caches method
8253 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008254
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008255- Bug #1776: __import__() no longer accepts filenames on any platform.
8256 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008257
Georg Brandlaed6c662008-01-07 17:25:53 +00008258- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8259
Georg Brandl3ee81df2008-05-17 18:14:43 +00008260- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8261 envvar and sys.dont_write_bytecode attribute. All these can be set
8262 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008263
Georg Brandl3ee81df2008-05-17 18:14:43 +00008264- Improve some exception messages when Windows fails to load an
8265 extension module. Now we get for example '%1 is not a valid Win32
8266 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008267

8271 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008272
Christian Heimes0a8143f2007-12-18 23:22:54 +00008273- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008274 and INF. float("nan"), float("inf") and float("-inf") now work on
8275 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008276
Georg Brandl3ee81df2008-05-17 18:14:43 +00008277- Compiler now generates simpler and faster code for dictionary
8278 literals. The oparg for BUILD_MAP now indicates an estimated
8279 dictionary size. There is a new opcode, STORE_MAP, for adding
8280 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008309- Patch #1739468: Directories and zipfiles containing a __main__.py
8310 file can now be directly executed by passing their name to the
8311 interpreter. The directory/zipfile is automatically inserted as the
8312 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008314- Issue #1265: Fix a problem with sys.settrace, if the tracing
8315 function uses a generator expression when at the same time the
8316 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008317
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008318- sets and frozensets now have an isdisjoint() method.
8319
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008320- optimize the performance of builtin.sum().
8321
Neal Norwitz44f326e2007-10-05 05:29:17 +00008322- Fix warnings found by the new version of the Coverity checker.
8323
Georg Brandl21e99f42010-03-07 15:23:59 +00008324- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008325 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8326 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008327
Georg Brandl3ee81df2008-05-17 18:14:43 +00008328- Issue #1686386: Tuple's tp_repr did not take into account the
8329 possibility of having a self-referential tuple, which is possible
8330 from C code. Nor did object's tp_str consider that a type's tp_str
8331 could do something that could lead to an inifinite recursion.
8332 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8333 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008334
Georg Brandl3ee81df2008-05-17 18:14:43 +00008335- Issue #1164: It was possible to trigger deadlock when using the
8336 'print' statement to write to a file since the GIL was not released
8337 as needed. Now PyObject_Print() does the right thing along with
8338 various tp_print implementations of the built-in types and those in
8339 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008340
Georg Brandl3ee81df2008-05-17 18:14:43 +00008341- Issue #1147: Exceptions were directly allowing string exceptions in
8342 their throw() method even though string exceptions no longer
8343 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008344
Georg Brandl3ee81df2008-05-17 18:14:43 +00008345- Issue #1096: Prevent a segfault from getting the repr of a very
8346 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008347
Brett Cannon1e534b52007-09-07 04:18:30 +00008348- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008349 PyObject_Call() never calling back out to Python code to trigger
8350 recursion depth updates/checks. Required the creation of a static
8351 RuntimeError instance in case normalizing an exception put the
8352 recursion check value past its limit. Fixes crashers
8353 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008354

Neal Norwitz0ac60192007-05-27 04:08:54 +00008368- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008369 __*__ attributes. (Some already existed, e.g., __doc__ and
8370 __name__.)

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008372- Add -3 option to the interpreter to warn about features that are
8373 deprecated and will be changed/removed in Python 3.0.
8374
Georg Brandl2134e752007-05-21 20:34:16 +00008375- Patch #1686487: you can now pass any mapping after '**' in function
8376 calls.
8377
Collin Winter62903052007-05-18 23:11:24 +00008378- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008379 "except E as target:". This is to provide forwards compatibility
8380 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008387- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008388 setting a plain string, ie don't expand to single letter identifiers.
8389
Raymond Hettinger13936692007-04-11 18:40:58 +00008390- Request #1191699: Slices can now be pickled.
8391
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008392- Request #1193128: str.translate() now allows a None argument for
8393 translations that only remove characters without re-mapping the
8394 remaining characters.
8395
Georg Brandl5cb76c12007-03-21 09:00:39 +00008396- Patch #1682205: a TypeError while unpacking an iterable is no longer
8397 masked by a generic one with the message "unpack non-sequence".
8398
Neal Norwitzaa754b72007-03-21 06:39:48 +00008399- Remove unused file Python/fmod.c.
8400
Guido van Rossum143b5642007-03-23 04:58:42 +00008401- Bug #1683368: The object.__init__() and object.__new__() methods are
8402 now stricter in rejecting excess arguments. The only time when
8403 either allows excess arguments is when it is not overridden and the
8404 other one is. For backwards compatibility, when both are
8405 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008406 warning later). Also, type.__init__() insists on the same signature
8407 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008409- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8410 object to complex using its __complex__() method before falling back
8411 to the __float__() method. Therefore, the functions in the cmath
8412 module now can operate on objects that define a __complex__()
8413 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009480 time so that opening a database previously created with the DB_DUP
9481 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9482 opens. Specifically: dictionary assignment to a DB object will
9483 replace all values for a given key when the database allows
9484 duplicate values. DB users should use DB.put(k, v) when they want
9485 to store duplicates; not DB[k] = v.

9492 characters with ASCII value less than 32. Also, it correctly quotes
9493 dots only if they occur on a single line, as opposed to the previous
9494 behavior of quoting dots if they are the second character of any
9495 line.
