Florent Xiclunac2279652012-02-12 14:49:03 +0100917- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100918 has left two versions of customize_compiler, the original in
919 distutils.sysconfig and another copy in distutils.ccompiler, with some
920 parts of distutils calling one and others using the other.
921 Complete the revert back to only having one in distutils.sysconfig as
922 is the case in 3.x.
923
Ned Deily0d0ea482012-02-10 12:59:06 +0100924- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
925 Distutils-based packages with C extension modules may fail because
926 Apple has removed gcc-4.2, the version used to build python.org
927 64-bit/32-bit Pythons. If the user does not explicitly override
928 the default C compiler by setting the CC environment variable,
929 Distutils will now attempt to compile extension modules with clang
930 if gcc-4.2 is required but not found. Also as a convenience, if
931 the user does explicitly set CC, substitute its value as the default
932 compiler in the Distutils LDSHARED configuration variable for OS X.
933 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
934 SDK, neither of which are available in Xcode 4. This change does not
935 attempt to override settings to support their use with Xcode 4.)

1020 raised when the wrapped raw file is non-blocking and the write would block.
1021 Previous code assumed that the raw write() would raise BlockingIOError, but

Ned Deily87e82bb2011-06-28 19:52:59 -07001208- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1209 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1210 interpreter process. This could cause failures in non-Distutils subprocesses
1211 and was unreliable since tests or user programs could modify the interpreter
1212 environment after Distutils set it. Instead, have Distutils set the the
1213 deployment target only in the environment of each build subprocess. It is
1214 still possible to globally override the default by setting
1215 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1216 greater or equal to the default value, the value with which the interpreter
1217 was built.

1247 the ticker doesn't have to wind down to zero from the old starting point
1248 before the new interval takes effect. And if the user increases the
1249 interval, it makes sure the new limit takes effect right away rather have an
1250 early task switch before recognizing the new interval.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002665- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2666 start byte and the continuation byte(s) are now considered invalid, instead
2667 of the number of bytes specified by the start byte.
2668 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2669 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2670 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2671 Previous versions returned a single u'\ufffd'.

2675 arises from the "Overriding __eq__ blocks inheritance ..." warning
2676 when turned into an exception: in this case the exception simply
2677 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002679- Issue #8748: Fix two issues with comparisons between complex and integer
2680 objects. (1) The comparison could incorrectly return True in some cases
2681 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2682 (2) The comparison raised an OverflowError for large integers, leading
2683 to unpredictable exceptions when combining integers and complex objects
2684 in sets or dicts.

Georg Brandlfee0f442010-05-22 21:26:21 +00002877- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2878 operation raises multiple signals and more than one of those signals is
2879 trapped, the specification determines the order in which the signals should be
2880 handled. In many cases this order wasn't being followed, leading to the wrong
2881 Python exception being raised.

3067 with a non-empty format string. This is an effort to future-proof user
3068 code. If a derived class does not currently implement __format__ but later
3069 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003070 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003071 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003121- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3122 InvalidOperation instead of returning False. (Comparisons involving a quiet
3123 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3124 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00003126- Issue #2531: Comparison operations between floats and Decimal instances now
3127 return a result based on the numeric values of the operands; previously they
3128 returned an arbitrary result based on the relative ordering of id(float) and
3129 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003131- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003132 argument `-` which tells it to read files to compile from stdin. Each line is
3133 read on demand and the named file is compiled immediately. (Original patch by
3134 Piotr Ożarowski).

3144 Fractions instance now raise TypeError instead of returning True/False. This
3145 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3146 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003250- Issue #1530559: When passing a non-integer argument to struct.pack with *any*

3255 the set of integer codes for which it was used differed between native packing
3256 and standard packing.)

3668
Mark Dickinson1b34d252010-01-01 17:27:30 +00003669- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003670 DeprecationWarning when passed a float argument where an integer was expected.
3671 These functions and methods now raise TypeError instead. The majority of the
3672 effects of this change are in the extension modules, but some core functions
3673 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3674 and many unicode/str methods.

3689 least on IEEE 754 platforms), and in particular does not depend on the
3690 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003836- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
3837 when called with invalid values.

Georg Brandlba83f822010-03-14 09:50:54 +00003839- Issue #3382: 'F' formatting for float and complex now convert the result to
3840 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3841 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003842
Georg Brandlba83f822010-03-14 09:50:54 +00003843- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3844 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003845
Georg Brandlba83f822010-03-14 09:50:54 +00003846- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3847 1e-100 used to raise OverflowError, but now gives the requested 120
3848 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00003849
Georg Brandlba83f822010-03-14 09:50:54 +00003850- Add Py3k warnings for parameter names in parentheses.

Georg Brandlba83f822010-03-14 09:50:54 +00003854- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
3855 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003856
Georg Brandlba83f822010-03-14 09:50:54 +00003857- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3858 decimal string that's guaranteed to round back to x under correct rounding
3859 (with round-half-to-even rounding mode). Previously it gave a string based on
3860 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3861 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3862 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003863
Georg Brandlba83f822010-03-14 09:50:54 +00003864- Issue #7117: On almost all platforms: float-to-string and string-to-float
3865 conversions within Python are now correctly rounded. Places these conversions
3866 occur include: str for floats and complex numbers; the float and complex
3867 constructors; old-style and new-style numeric formatting; serialization and
3868 deserialization of floats and complex numbers using marshal, pickle and json;
3869 parsing of float and imaginary literals in Python code; Decimal-to-float
3870 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003871
Georg Brandlba83f822010-03-14 09:50:54 +00003872 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3873 providing correctly-rounded strtod and dtoa C functions. This code is
3874 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3875 the C compiler. There may be a small number of platforms on which correct
3876 operation of this code cannot be guaranteed, so the code is not used: notably,
3877 this applies to platforms where the C double format is not IEEE 754 binary64,
3878 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3879 and Python's configure script is unable to determine how to change the FPU
3880 precision. On these platforms conversions use the platform strtod and dtoa,
3881 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003882
Georg Brandlba83f822010-03-14 09:50:54 +00003883- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3884 uses the correctly-rounded string <-> float conversions described above (when
3885 available), and so produces correctly rounded results that will display nicely
3886 under the float repr. There are two related small changes: (1) round now
3887 accepts any class with an ``__index__()`` method for its second argument (but
3888 no longer accepts floats for the second argument), and (2) an excessively
3889 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3890 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00003892- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
3893
Georg Brandlba83f822010-03-14 09:50:54 +00003894- Fix several issues with ``compile()``. The input can now contain Windows and
3895 Mac newlines and is no longer required to end in a newline.

Georg Brandlba83f822010-03-14 09:50:54 +00004037- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4038 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4039 but with at least one decimal point and with a default precision
4040 of 12. Previously, the behavior the same but with a default precision of 6.
4041 This more closely matches ``str()``, and reduces surprises when adding
4042 alignment flags to the empty presentation type. This also affects the new
4043 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00004052- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
4053 '.5')`` now produces a sensible result.
Eric Smith9139cc62009-04-30 00:58:58 +00004054
Georg Brandlba83f822010-03-14 09:50:54 +00004055- Issue #5864: Fix empty format code formatting for floats so that it never
4056 gives more than the requested number of significant digits.
Mark Dickinson92fcc9c2009-04-29 20:41:00 +00004057
Georg Brandlba83f822010-03-14 09:50:54 +00004058- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new

4062 not their own uppercase.
Martin v. Löwis99f27792009-04-26 00:53:18 +00004063
Eric Smith068f0652009-04-25 21:40:15 +00004064- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
4065 _PyOS_double_to_string or PyOS_double_to_string.
4066
Benjamin Peterson5083dc52009-04-25 00:41:22 +00004067- Issue #5283: Setting __class__ in __del__ caused a segfault.
4068
Georg Brandlba83f822010-03-14 09:50:54 +00004069- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
4070 nans, infs or negative zeros.

Georg Brandlba83f822010-03-14 09:50:54 +00004078- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
4079 type code and we have an exponent.
Eric Smithaca19e62009-04-22 13:29:05 +00004080
Georg Brandlba83f822010-03-14 09:50:54 +00004081- Issue #3166: Make long -> float (and int -> float) conversions correctly

Georg Brandlba83f822010-03-14 09:50:54 +00004087- Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was
4088 giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00004107- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00004108 untrackable objects are not tracked by the garbage collector. This can reduce
4109 the size of collections and therefore the garbage collection overhead on
4110 long-running programs, depending on their particular use of datatypes.
Antoine Pitrouf8387af2009-03-23 18:41:45 +00004111
Georg Brandlba83f822010-03-14 09:50:54 +00004112- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its

4114 150% faster.
Mark Dickinson0b666bf2009-03-23 18:25:13 +00004115
Georg Brandlba83f822010-03-14 09:50:54 +00004116- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
4117 internal representation of integers, for performance reasons. Base 2**30 is
4118 enabled by default on 64-bit machines. Add --enable-big-digits option to
4119 configure, which overrides the default. Add sys.long_info structseq to
4120 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00004121
Benjamin Peterson6ffe8522009-03-18 20:52:15 +00004122- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
4123 result traceback.__members__ no longer exists.)
4124
Georg Brandlba83f822010-03-14 09:50:54 +00004125- Issue #4474: PyUnicode_FromWideChar now converts characters outside the BMP to
4126 surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE)
4127 == 2.
Mark Dickinson6b265f12009-03-18 16:07:26 +00004128
Georg Brandlba83f822010-03-14 09:50:54 +00004129- Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{}
4130 {}'.format(1, 2) == '1 2'``.
Eric Smith6f42edb2009-03-14 11:57:26 +00004131
Georg Brandlba83f822010-03-14 09:50:54 +00004132- Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a
Brett Cannon6c4cff02009-03-11 04:51:06 +00004133 requirement. Means the DeprecationWarning from Python 2.6 can go away.
4134
Georg Brandlba83f822010-03-14 09:50:54 +00004135- Issue #5247: Improve error message when unknown format codes are used when
4136 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00004137
Georg Brandlba83f822010-03-14 09:50:54 +00004138- Running Python with the -3 option now also warns about classic division for
4139 ints and longs.
Raymond Hettinger08259e82009-02-18 23:10:19 +00004140
Georg Brandlba83f822010-03-14 09:50:54 +00004141- Issue #5260: Long integers now consume less memory: average saving is 2 bytes
4142 per long on a 32-bit system and 6 bytes per long on a 64-bit system.
Mark Dickinson2ffb26f2009-02-15 10:13:41 +00004143
Antoine Pitrou76a4b892009-02-13 13:52:33 +00004144- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
4145 rotating the object pointer by 4 bits to the right.
4146
Georg Brandlba83f822010-03-14 09:50:54 +00004147- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now
4148 forces its argument to double before testing for infinity.
Mark Dickinsonc97c9092009-02-09 14:18:43 +00004149
Benjamin Petersone18ef192009-01-20 14:21:16 +00004150- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
4151
Georg Brandl29c6a282009-04-05 20:23:13 +00004152- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00004153 were suppressing all exceptions. These include list(), filter(), map(),
4154 zip(), and bytearray().
4155
Benjamin Peterson596d3062009-01-19 15:42:23 +00004156- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
4157 functions.
4158
Benjamin Peterson5848d1f2009-01-19 00:08:08 +00004159- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
4160 OSError.
4161
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +00004162- Issue #4807: Port the _winreg module to Windows CE.
4163
Georg Brandlba83f822010-03-14 09:50:54 +00004164- Issue #4935: The overflow checking code in the expandtabs() method common to
4165 str, bytes and bytearray could be optimized away by the compiler, letting the
4166 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00004167
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00004168- Issue #3720: Fix a crash when an iterator modifies its class and removes its
4169 __next__ method.
4170

4174
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00004175- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
4176 collecting the oldest generation) so that allocating lots of objects without
4177 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00004178 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00004179 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

4182
Georg Brandlba83f822010-03-14 09:50:54 +00004183- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4184 existing .py counterpart, override the co_filename attributes of all code
4185 objects if the original filename is obsolete (which can happen if the file has
4186 been renamed, moved, or if it is accessed through different paths). Patch by
4187 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00004188
Georg Brandlba83f822010-03-14 09:50:54 +00004189- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00004191- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
4192 file with `str' filename on Windows.
4193
Antoine Pitrouaa687902009-01-01 14:11:22 +00004194- Issue #3680: Reference cycles created through a dict, set or deque iterator
4195 did not get collected.
4196
Georg Brandlba83f822010-03-14 09:50:54 +00004197- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
4198 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00004199
Benjamin Peterson7af65562008-12-29 17:56:58 +00004200- Issue #4764: With io.open, IOError.filename is set when trying to open a
4201 directory on POSIX systems.
4202
Benjamin Petersonfe231b02008-12-29 17:47:42 +00004203- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
4204 systems.
4205
Georg Brandl6425a2f2008-12-28 11:54:53 +00004206- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004207 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00004208
Skip Montanarof205c132008-12-23 03:30:15 +00004209- Added test case to ensure attempts to read from a file opened for writing
4210 fail.
4211
Georg Brandlba83f822010-03-14 09:50:54 +00004212- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
4213 elapsed times, not only when some objects are uncollectable/unreachable.
4214 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00004215

Georg Brandlba83f822010-03-14 09:50:54 +00004226- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4227 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4228 instances. On a typical machine this saves 3 bytes of memory (on average) per
4229 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004230
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004231- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4232 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4233 instead of throwing a MemoryError.
4234
Georg Brandlba83f822010-03-14 09:50:54 +00004235- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4236 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004237
Benjamin Petersonc078f922008-11-21 22:27:24 +00004238- Issue #4367: Python would segfault during compiling when the unicodedata
4239 module couldn't be imported and \N escapes were present.
4240
Georg Brandlba83f822010-03-14 09:50:54 +00004241- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4242 file objects with closefd=False. The file descriptor is still kept open but
4243 the file object behaves like a closed file. The ``FileIO`` object also got a
4244 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004245
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004246- Issue #4348: Some bytearray methods returned that didn't cause any change to
4247 the bytearray, returned the same bytearray instead of a copy.
4248
Georg Brandlba83f822010-03-14 09:50:54 +00004249- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

4252
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004253- Issue #4048: The parser module now correctly validates relative imports.
4254
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004255- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

4262 __future__ import didn't work.
4263
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004264- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004265 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004266
Georg Brandlba83f822010-03-14 09:50:54 +00004267- On windows, ``os.chdir()`` given unicode was not working if
4268 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4269 this code path is really executed because I cannot move to such directory on
4270 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004271
Georg Brandlba83f822010-03-14 09:50:54 +00004272- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4273 element is temporarily replaced with an equivalent frozenset. But the
4274 eventual KeyError would always report the empty ``frozenset()`` as the missing
4275 key. Now it correctly refers to the initial element.

5669-----------------
5670
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005671- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5672
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005673- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5674 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5675 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5676 ``printf`` function, whereas PyString_FromFormat has an independent
5677 implementation and uses "%zd" on all platforms for size_t values.
5678 This makes a difference on win64, where ``printf`` needs "%Id" to display
5679 64bit values.
5680
Benjamin Peterson97179b02008-09-09 20:55:01 +00005681- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5682 error.
5683
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005684- Issue #3777: long() applied to a float object now always return a long
5685 object; previously an int would be returned for small values. the __long__
5686 method is allowed to return either an int or a long, but the behaviour of
5687 float objects should not change to respect backward compatibility.
5688
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005689- Issue #3751: str.rpartition would perform a left-partition when called with
5690 a unicode argument.
5691
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005692- Issue #3683: Fix compilation when --without-threads is given.
5693
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005694- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005695 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005696 was correctly parsed but parsing of subsequent arguments failed.
5697
Vinay Sajip35e3b032008-09-01 14:33:59 +00005698- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005699 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5700 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5701 when given a tuple of classes as second argument, were looking up
5702 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5703 type object.
5704
Neal Norwitz18aa3882008-08-24 05:04:52 +00005705- Fix crashes on memory allocation failure found with failmalloc.
5706
5707- Fix memory leaks found with valgrind and update suppressions file.
5708
5709- Fix compiler warnings in opt mode which would lead to invalid memory reads.
5710
5711- Fix problem using wrong name in decimal module reported by pychecker.
5712
Christian Heimes7d4c3172008-08-22 19:47:25 +00005713- Silenced another compiler warning about a used but not defined
5714 function 'stringlib_contains_obj'.
5715
Benjamin Peterson712ee922008-08-24 18:10:20 +00005716- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5717 ``__delslice__``.
5718
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00005719- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
5720 library targets in the Makefile.
5721
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005722- Issue #1204: The configure script now tests for additional libraries
5723 that may be required when linking against readline. This fixes issues
5724 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
5725

5733
Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00005734- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
5735 stack usage in the case of deeply nested objects.
5736

Nick Coghland2e09382008-09-11 12:11:06 +00005747- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00005748 return a list or None rather than a custom object.
5749
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00005750- Issue #1638033: Cookie.Morsel gained the httponly attribute.
5751
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00005752- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon32476fc2008-09-05 18:33:51 +00005755
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +00005756- Issue #3762: platform.architecture() fails if python is lanched via
5757 its symbolic link.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005774 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5775 for catch_warnings() also led to an improvement in the raising of a
5776 DeprecationWarning related to warnings.warn_explicit().
5777
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005778- The deprecation warnings for the old camelCase threading API were removed.

5800
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005801- Issue #2975: When compiling several extension modules with Visual Studio 2008
5802 from the same python interpreter, some environment variables would grow
5803 without limit.
5804
Benjamin Peterson37346b22008-08-23 20:27:43 +00005805- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5806 exploitation of poor argument checking.
5807
Gerhard Häringef2276b2008-09-12 13:54:06 +00005808- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Nick Coghland2e09382008-09-11 12:11:06 +00005820- Issue #3781: Add test.test_support.check_warnings() as a convenience
5821 wrapper for warnings.catch_warnings() that makes it easier to check
5822 that expected warning messages are being reported.
5823
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00005824- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005842What's New in Python 2.6 beta 3?
5843================================

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005846
5847Core and Builtins
5848-----------------
5849
Guido van Rossumf8402962008-08-20 15:01:50 +00005850- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5851 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5852 extensions do not automatically benefit from the class attribute
5853 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5854 to their tp_flags field if they care. This is a backwards
5855 compatibility feature; in 3.0, all types will use the cache by
5856 default.
5857
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005858- Keyword arguments can now follow starred arguments. (``f(a, *args,
5859 keyword=23)`` is now valid syntax.)
5860
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005861- ctypes function pointers that are COM methods have a boolean True
5862 value again.
5863
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005864- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5865 by denying s# to parse objects that have a releasebuffer procedure,
5866 and introducing s*.
5867
Georg Brandl1e13ea92008-08-11 09:07:59 +00005868- Issue #3537: Fix an assertion failure when an empty but presized dict
5869 object was stored in the freelist.
5870
Mark Dickinsonb6467572008-08-04 21:30:09 +00005871- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5872 ValueError consistently across platforms.
5873
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005874- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5875 (64bit Unix, for example), unichr() would truncate its argument and return
5876 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5877
Neal Norwitze7d8be82008-07-31 17:17:14 +00005878- Apply security patches from Apple.
5879
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005880- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5881 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5882
Antoine Pitrou92f82162008-07-25 22:22:08 +00005883- Issue #1819: function calls with several named parameters are now on
5884 average 35% faster (as measured by pybench).
5885
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005886- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5887 the python debugger steps into a class statement: the free variables (local
5888 variables defined in an outer scope) would be deleted from the outer scope.
5889
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005890- Issue #2620: Overflow checking when allocating or reallocating memory
5891 was not always being done properly in some python types and extension
5892 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5893 all been updated to perform better checks and places in the code that
5894 would previously leak memory on the error path when such an allocation
5895 failed have been fixed.

5898-------
5899
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005900- Issue #3612: Added some missing basic types in ctypes.wintypes.
5901
Benjamin Petersone977ad42008-08-20 01:42:01 +00005902- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5903 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5904
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005905- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5906 version reported by these tools does not necessarily follow the python
5907 version numbering scheme, so the module is less strict when parsing it.
5908
Nick Coghlanf70385a2008-08-18 12:42:46 +00005909- Issue #2235: Added Py3k warnings for types which will become unhashable
5910 under the stricter __hash__ inheritance rules in 3.0. Several types
5911 which did not meet the rules for hash invariants and were already
5912 unhashable in 3.0 have now been explicitly flagged as unhashable in
5913 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5914 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5915
Brett Cannon88f801d2008-08-18 00:46:22 +00005916- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5917 imported into the module but exposed as part of the module's API.
5918
Brett Cannon7b96f072008-08-18 00:41:11 +00005919- Remove an unneeded import of abc.ABCMeta from 'inspect'.

5924
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005925- Issue #3575: Incremental decoder's decode function now takes bytearray
5926 by using 's*' instead of 't#'.
5927
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005928- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005929 fails unicode conversion on 2nd parameter. (windows only)
5930
Georg Brandl222e2082010-08-01 22:27:39 +00005931- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005932 in a redirect.
5933
Brett Cannonabe423e2008-08-16 21:47:07 +00005934- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005935 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005936
Facundo Batistaeb90b782008-08-16 14:44:07 +00005937- Issue #2776: fixed small issue when handling an URL with double slash
5938 after a 302 response in the case of not going through a proxy.
5939
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005940- Issue #2676: in the email package, content-type parsing was hanging on
5941 pathological input because of quadratic or exponential behaviour of a
5942 regular expression.
5943
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005944- Issue #3476: binary buffered reading through the new "io" library is now
5945 thread-safe.
5946
Brett Cannonbf3157b2008-08-14 05:00:03 +00005947- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5948 since mimetools itself is deprecated. Because modules are cached, all
5949 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5950

6029
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006030- Issue #643841: The language reference now provides more detailed

6042-----------------
6043
Georg Brandl3e483f62008-07-16 22:57:41 +00006044- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6045 its methods now allow for items objects that can be converted to
6046 an integer using operator.index().
6047
Mark Dickinson64b7e502008-07-16 09:40:03 +00006048- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6049 produced a ValueError instead of giving the correct float.
6050
Eric Smitha5fa5a22008-07-16 00:11:49 +00006051- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6052 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6053
Mark Dickinson7103aa42008-07-15 19:08:33 +00006054- Issue #3008: the float type has a new instance method 'float.hex'
6055 and a new class method 'float.fromhex' to convert floating-point
6056 numbers to and from hexadecimal strings, respectively.
6057
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006058- Issue #2235: __hash__ is once again inherited by default. To allow
6059 collections.Hashable to remain meaningful in the presence of the
6060 default hash implementation (object.__hash__), it is now possible
6061 to explicit block inheritance of hash by setting __hash__=None at
6062 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6063 level.
6064
Nick Coghlanb028f502008-07-13 14:52:36 +00006065- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6066 the parent module cannot be found while performing an absolute import.
6067 This means that an incorrectly defined __package__ attribute will
6068 now only prevent relative imports in that module rather than causing
6069 all imports from that module to fail.
6070
Nick Coghlan14ff9942008-07-08 14:21:42 +00006071- Issue #2517: Allow unicode messages in Exceptions again by correctly

6081 another thread's dictionary.
6082
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006083- Issue #3004: Minor change to slice.indices(): the start and stop
6084 arguments are now treated identically, making the behaviour easier
6085 to describe and understand. For example, slice(None, -10,
6086 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6087 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6088 10, -1).
6089
Georg Brandl278fc502008-07-19 12:46:12 +00006090- Issue #3219: Calling a function with repeated keyword arguments,
6091 f(a=2, a=23), would not cause a syntax error. This was a regression
6092 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006130- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6131 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006132 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006133 content-length. The problem had been corrected in the 2.4 branch, but never

6518 in Python 3.0.
Benjamin Peterson23681932008-05-12 21:42:13 +00006519
Vinay Sajip9828b7e2008-06-17 11:04:02 +00006520- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006521 environment to control the '-arch' flags that are used to build
6522 an extension. This was added for compatibility with Apple's build
6523 of Python.
6524
6525- The bundled OSX-specific copy of libbffi is now in sync with the version
6526 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
6527
Georg Brandl25c34082008-08-18 23:09:49 +00006528- The threading module gained aliases for names that will be removed in the

6537
Brett Cannonb61d8012008-05-11 23:39:04 +00006538- ``Lib/lib-old`` is now added to sys.path.
6539
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006540- On MacOS X it is now possible to install the framework in 64-bit
6541 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006542 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006543
6544 This is controlled by the configure argument ``--with-universal-archs``:
6545
6546 - ``--with-universal-archs=all``: install 4-way universal
6547
6548 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6549
6550 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6551
6552 This option should be used in combination with ``--enable-universalsdk=``.
6553
6554 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 +00006604- Issue #1631171: Re-implement the 'warnings' module in C (the
6605 original Python code has been kept as backup). This will allow for
6606 using the 'warning's machinery in such places as the parser where
6607 use of pure Python code is not possible. Both the ``showarning()``
6608 and ``formatwarning()`` gain an optional 'line' argument which is
6609 not called by default for backwards-compatibility reasons. Setting
6610 ``warnings.showwarning()`` to an implementation that lacks support
6611 for the ``line`` argument will raise a DeprecationWarning.

6635
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006636- The getpass module has been improved on Unix. It now uses /dev/tty
6637 by default and uses stderr instead of stdout. A GetPassWarning is
6638 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006653- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006654 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006674- Issue #2550: The approach used by client/server code for obtaining
6675 ports to listen on in network-oriented tests has been refined in an
6676 effort to facilitate running multiple instances of the entire
6677 regression test suite in parallel without issue.
6678 test_support.bind_port() has been fixed such that it will always
6679 return a unique port -- which wasn't always the case with the
6680 previous implementation, especially if socket options had been set
6681 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6682 new implementation of bind_port() will actually raise an exception
6683 if it is passed an AF_INET/SOCK_STREAM socket with either the
6684 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6685 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6686 the socket it's been passed. This currently only applies to
6687 Windows. This option prevents any other sockets from binding to the
6688 host/port we've bound to, thus removing the possibility of the
6689 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6690 when a second SOCK_STREAM socket binds and accepts to a host/port
6691 that's already been bound by another socket. The optional preferred
6692 port parameter to bind_port() has been removed. Under no
6693 circumstances should tests be hard coding ports!
6694
6695 test_support.find_unused_port() has also been introduced, which will
6696 pass a temporary socket object to bind_port() in order to obtain an
6697 unused port. The temporary socket object is then closed and
6698 deleted, and the port is returned. This method should only be used
6699 for obtaining an unused port in order to pass to an external program
6700 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6701 a parameter to a server-oriented class that doesn't give you direct
6702 access to the underlying socket used.
6703
6704 Finally, test_support.HOST has been introduced, which should be used
6705 for the host argument of any relevant socket calls (i.e. bind and
6706 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006707
6708 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006709 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006710 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6711 test_asynchat and test_socket_ssl.
6712
Georg Brandl3ee81df2008-05-17 18:14:43 +00006713 It is now possible for multiple instances of the regression test
6714 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006993- Added the future_builtins module, which contains hex() and oct().
6994 These are the PEP 3127 version of these functions, designed to be
6995 compatible with the hex() and oct() builtins from Python 3.0. They
6996 differ slightly in their output formats from the existing, unchanged
6997 Python 2.6 builtins. The expected usage of the future_builtins
6998 module is:
6999 from future_builtins import hex, oct
7000
Eric Smith7ef40bf2008-02-20 23:34:22 +00007001- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7002 exponents for exponents with absolute value < 100. Follows C99
7003 standard. This is a change on Windows, which would use 3 digits.
7004 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7005 so that any alterations it does to the resulting string will be
7006 available in stringlib/formatter.h (for float.__format__).
7007
Eric Smith5a3c1352008-02-19 13:21:56 +00007008- Implemented PEP 3101, Advanced String Formatting. This adds a new
7009 builtin format(); a format() method for str and unicode; a
7010 __format__() method to object, str, unicode, int, long, float, and
7011 datetime; the class string.Formatter; and the C API
7012 PyObject_Format().
7013
Georg Brandl3ee81df2008-05-17 18:14:43 +00007014- Fixed several potential crashes, all caused by specially crafted
7015 __del__ methods exploiting objects in temporarily inconsistent
7016 state.

7020 a slot on a registered virtual subclass.

7026 in order to allow pymalloc to free more arenas. Python may give back
7027 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007028
Georg Brandl3ee81df2008-05-17 18:14:43 +00007029- Issue #2045: Fix an infinite recursion triggered when printing a
7030 subclass of collections.defaultdict, if its default_factory is set
7031 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007032
Christian Heimesf75dbef2008-02-08 00:11:31 +00007033- Fixed a minor memory leak in dictobject.c. The content of the free
7034 list was not freed on interpreter shutdown.

Georg Brandl21e99f42010-03-07 15:23:59 +00007036- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007037 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007038
Georg Brandl3ee81df2008-05-17 18:14:43 +00007039- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7040 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007041 to compact the internal free lists of pre-allocted ints and floats.
7042
Georg Brandl3ee81df2008-05-17 18:14:43 +00007043- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7044 calls. Python expected the return type int but the fork familie
7045 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007046
Georg Brandl3ee81df2008-05-17 18:14:43 +00007047- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7048 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007049
Georg Brandl3ee81df2008-05-17 18:14:43 +00007050- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7051 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007052
Georg Brandl3ee81df2008-05-17 18:14:43 +00007053- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7054 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00007056- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7057 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007058
Georg Brandl3ee81df2008-05-17 18:14:43 +00007059- Patch #1473257: generator objects gain a gi_code attribute. This is
7060 the same object as the func_code attribute of the function that
7061 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007062
Georg Brandl3ee81df2008-05-17 18:14:43 +00007063- Issue #1920: "while 0" statements were completely removed by the
7064 compiler, even in the presence of an "else" clause, which is
7065 supposed to be run when the condition is false. Now the compiler
7066 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007067
Guido van Rossumeead05f2008-01-24 18:21:02 +00007068- A few crashers fixed: weakref_in_del.py (issue #1377858);
7069 loosing_dict_ref.py (issue #1303614, test67.py);
7070 borrowed_ref_[34].py (not in tracker).
7071
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007072- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007073 suppressed while an extension is loaded by calling SetErrorMode in
7074 dynload_win.c. The error is still reported properly.
7075
Georg Brandl3ee81df2008-05-17 18:14:43 +00007076- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007077 several extension methods and modules do not work without unicode
7078 support.
7079
Georg Brandl26543b12008-01-21 18:36:51 +00007080- Issue #1882: when compiling code from a string, encoding cookies in the
7081 second line of code were not always recognized correctly.
7082
Georg Brandl14404b62008-01-19 19:27:05 +00007083- Issue #1679: "0x" was taken as a valid integer literal.
7084
Georg Brandl6caad7d2008-01-26 14:19:22 +00007085- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007086 added.
7087
Christian Heimesc94e2b52008-01-14 04:13:37 +00007088- sys.float_info / PyFloat_GetInfo: The floating point information
7089 object was converted from a dict to a specialized structseq object.
7090
Georg Brandl3ee81df2008-05-17 18:14:43 +00007091- Patch #1816: Added sys.flags structseq. It exposes the status of
7092 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007093
Georg Brandl3ee81df2008-05-17 18:14:43 +00007094- Objects/structseq.c: Implemented new structseq representation. The
7095 patch makes structseqs (e.g. the return value of os.stat) more
7096 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007097
Georg Brandl3ee81df2008-05-17 18:14:43 +00007098- Patch #1700288: added a type attribute cache that caches method
7099 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007100
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007101- Bug #1776: __import__() no longer accepts filenames on any platform.
7102 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007103
Georg Brandlaed6c662008-01-07 17:25:53 +00007104- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7105
Georg Brandl3ee81df2008-05-17 18:14:43 +00007106- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7107 envvar and sys.dont_write_bytecode attribute. All these can be set
7108 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007109
Georg Brandl3ee81df2008-05-17 18:14:43 +00007110- Improve some exception messages when Windows fails to load an
7111 extension module. Now we get for example '%1 is not a valid Win32
7112 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007113
Georg Brandl3ee81df2008-05-17 18:14:43 +00007114- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007116- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7117 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007118
Christian Heimes0a8143f2007-12-18 23:22:54 +00007119- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007120 and INF. float("nan"), float("inf") and float("-inf") now work on
7121 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007122
Georg Brandl3ee81df2008-05-17 18:14:43 +00007123- Compiler now generates simpler and faster code for dictionary
7124 literals. The oparg for BUILD_MAP now indicates an estimated
7125 dictionary size. There is a new opcode, STORE_MAP, for adding
7126 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007127
Georg Brandl3ee81df2008-05-17 18:14:43 +00007128- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007136- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007137 SystemError.
7138
Nick Coghlanef01d822007-12-03 12:55:17 +00007139- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00007155- Patch #1739468: Directories and zipfiles containing a __main__.py
7156 file can now be directly executed by passing their name to the
7157 interpreter. The directory/zipfile is automatically inserted as the
7158 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007159
Georg Brandl3ee81df2008-05-17 18:14:43 +00007160- Issue #1265: Fix a problem with sys.settrace, if the tracing
7161 function uses a generator expression when at the same time the
7162 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007163
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007164- sets and frozensets now have an isdisjoint() method.
7165
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007166- optimize the performance of builtin.sum().
7167
Neal Norwitz44f326e2007-10-05 05:29:17 +00007168- Fix warnings found by the new version of the Coverity checker.
7169
Georg Brandl21e99f42010-03-07 15:23:59 +00007170- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007171 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7172 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007173
Georg Brandl3ee81df2008-05-17 18:14:43 +00007174- Issue #1686386: Tuple's tp_repr did not take into account the
7175 possibility of having a self-referential tuple, which is possible
7176 from C code. Nor did object's tp_str consider that a type's tp_str
7177 could do something that could lead to an inifinite recursion.
7178 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7179 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007180
Georg Brandl3ee81df2008-05-17 18:14:43 +00007181- Issue #1164: It was possible to trigger deadlock when using the
7182 'print' statement to write to a file since the GIL was not released
7183 as needed. Now PyObject_Print() does the right thing along with
7184 various tp_print implementations of the built-in types and those in
7185 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007186
Georg Brandl3ee81df2008-05-17 18:14:43 +00007187- Issue #1147: Exceptions were directly allowing string exceptions in
7188 their throw() method even though string exceptions no longer
7189 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007190
Georg Brandl3ee81df2008-05-17 18:14:43 +00007191- Issue #1096: Prevent a segfault from getting the repr of a very
7192 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007193
Brett Cannon1e534b52007-09-07 04:18:30 +00007194- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007195 PyObject_Call() never calling back out to Python code to trigger
7196 recursion depth updates/checks. Required the creation of a static
7197 RuntimeError instance in case normalizing an exception put the
7198 recursion check value past its limit. Fixes crashers
7199 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007200
Georg Brandl3ee81df2008-05-17 18:14:43 +00007201- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007214- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007215 __*__ attributes. (Some already existed, e.g., __doc__ and
7216 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007217
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007218- Add -3 option to the interpreter to warn about features that are
7219 deprecated and will be changed/removed in Python 3.0.
7220
Georg Brandl2134e752007-05-21 20:34:16 +00007221- Patch #1686487: you can now pass any mapping after '**' in function
7222 calls.
7223
Collin Winter62903052007-05-18 23:11:24 +00007224- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007225 "except E as target:". This is to provide forwards compatibility
7226 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00007228- Deprecate BaseException.message as per PEP 352.
7229
Georg Brandl3ee81df2008-05-17 18:14:43 +00007230- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007231 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007232
Vinay Sajip8549ce32007-05-06 17:53:37 +00007233- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007234 setting a plain string, ie don't expand to single letter identifiers.
7235
Raymond Hettinger13936692007-04-11 18:40:58 +00007236- Request #1191699: Slices can now be pickled.
7237
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007238- Request #1193128: str.translate() now allows a None argument for
7239 translations that only remove characters without re-mapping the
7240 remaining characters.
7241
Georg Brandl5cb76c12007-03-21 09:00:39 +00007242- Patch #1682205: a TypeError while unpacking an iterable is no longer
7243 masked by a generic one with the message "unpack non-sequence".
7244
Neal Norwitzaa754b72007-03-21 06:39:48 +00007245- Remove unused file Python/fmod.c.
7246
Guido van Rossum143b5642007-03-23 04:58:42 +00007247- Bug #1683368: The object.__init__() and object.__new__() methods are
7248 now stricter in rejecting excess arguments. The only time when
7249 either allows excess arguments is when it is not overridden and the
7250 other one is. For backwards compatibility, when both are
7251 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007252 warning later). Also, type.__init__() insists on the same signature
7253 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007254
Georg Brandl3ee81df2008-05-17 18:14:43 +00007255- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7256 object to complex using its __complex__() method before falling back
7257 to the __float__() method. Therefore, the functions in the cmath
7258 module now can operate on objects that define a __complex__()
7259 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008333 time so that opening a database previously created with the DB_DUP
8334 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8335 opens. Specifically: dictionary assignment to a DB object will
8336 replace all values for a given key when the database allows
8337 duplicate values. DB users should use DB.put(k, v) when they want
8338 to store duplicates; not DB[k] = v.

8345 characters with ASCII value less than 32. Also, it correctly quotes
8346 dots only if they occur on a single line, as opposed to the previous
8347 behavior of quoting dots if they are the second character of any
8348 line.
