16 is modified during the lifetime of the Python process after zipimport has
17 already cached the zip's table of contents we detect this and recover

1628 In particular, fix extension module build failures when trying to use
1629 32-bit-only installer Pythons on systems with Xcode 4 (currently
1630 OS X 10.8, 10.7, and optionally 10.6).
1631 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1632 * Since Xcode 4 removes ppc support, extension module builds now
1633 check for ppc compiler support and by default remove ppc and
1634 ppc64 archs when they are not available.
1635 * Extension module builds now revert to using system installed
1636 headers and libs (/usr and /System/Library) if the SDK used
1637 to build the interpreter is not installed or has moved.
1638 * Try to avoid building extension modules with deprecated
1639 and problematic Apple llvm-gcc compiler. If original compiler
1640 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01002064- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002065 has left two versions of customize_compiler, the original in
2066 distutils.sysconfig and another copy in distutils.ccompiler, with some
2067 parts of distutils calling one and others using the other.

2070
Ned Deily0d0ea482012-02-10 12:59:06 +01002071- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2072 Distutils-based packages with C extension modules may fail because
2073 Apple has removed gcc-4.2, the version used to build python.org
2074 64-bit/32-bit Pythons. If the user does not explicitly override
2075 the default C compiler by setting the CC environment variable,
2076 Distutils will now attempt to compile extension modules with clang
2077 if gcc-4.2 is required but not found. Also as a convenience, if
2078 the user does explicitly set CC, substitute its value as the default
2079 compiler in the Distutils LDSHARED configuration variable for OS X.
2080 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2081 SDK, neither of which are available in Xcode 4. This change does not
2082 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002332- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2333 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2334 interpreter process. This could cause failures in non-Distutils subprocesses
2335 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002336 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002337 deployment target only in the environment of each build subprocess. It is
2338 still possible to globally override the default by setting
2339 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2340 greater or equal to the default value, the value with which the interpreter
2341 was built.

2371 the ticker doesn't have to wind down to zero from the old starting point
2372 before the new interval takes effect. And if the user increases the
2373 interval, it makes sure the new limit takes effect right away rather have an
2374 early task switch before recognizing the new interval.

3815-----------------
3816
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003817- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3818 start byte and the continuation byte(s) are now considered invalid, instead
3819 of the number of bytes specified by the start byte.
3820 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3821 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3822 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3823 Previous versions returned a single u'\ufffd'.
3824
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003825- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00003826 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
3827 arises from the "Overriding __eq__ blocks inheritance ..." warning
3828 when turned into an exception: in this case the exception simply
3829 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00003830
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003831- Issue #8748: Fix two issues with comparisons between complex and integer
3832 objects. (1) The comparison could incorrectly return True in some cases
3833 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3834 (2) The comparison raised an OverflowError for large integers, leading
3835 to unpredictable exceptions when combining integers and complex objects
3836 in sets or dicts.
3837
Mark Dickinson81336372010-05-30 12:12:25 +00003838- Issue #5211: Implicit coercion for the complex type is now completely
3839 removed. (Coercion for arithmetic operations was already removed in 2.7
3840 alpha 4, but coercion for rich comparisons was accidentally left in.)
3841
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00003842- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
3843 and error handler, instead of writing to the C stderr file in utf-8
3844
Georg Brandlfee0f442010-05-22 21:26:21 +00003845- Issue #7902: When using explicit relative import syntax, don't try implicit

Georg Brandlfee0f442010-05-22 21:26:21 +00004029- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4030 operation raises multiple signals and more than one of those signals is
4031 trapped, the specification determines the order in which the signals should be
4032 handled. In many cases this order wasn't being followed, leading to the wrong
4033 Python exception being raised.

4219 with a non-empty format string. This is an effort to future-proof user
4220 code. If a derived class does not currently implement __format__ but later
4221 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004222 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004223 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004273- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4274 InvalidOperation instead of returning False. (Comparisons involving a quiet
4275 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4276 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004278- Issue #2531: Comparison operations between floats and Decimal instances now
4279 return a result based on the numeric values of the operands; previously they
4280 returned an arbitrary result based on the relative ordering of id(float) and
4281 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004283- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004284 argument `-` which tells it to read files to compile from stdin. Each line is
4285 read on demand and the named file is compiled immediately. (Original patch by
4286 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +00004295- Comparisons using one of <, <=, >, >= between a complex instance and a
4296 Fractions instance now raise TypeError instead of returning True/False. This
4297 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4298 <=> complex, and complex <=> complex comparisons.

4398 integer format code, struct.pack first attempts to convert the non-integer

4401
Georg Brandlba83f822010-03-14 09:50:54 +00004402- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
4403 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
4404 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00004405 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
4406 inconsistent: __int__ was used for some integer codes but not for others, and
4407 the set of integer codes for which it was used differed between native packing
4408 and standard packing.)

4813-----------------
4814
Georg Brandlba83f822010-03-14 09:50:54 +00004815- The ``__complex__()`` method is now looked up on the class of instances to
4816 make it consistent with other special methods.

4820
Mark Dickinson1b34d252010-01-01 17:27:30 +00004821- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004822 DeprecationWarning when passed a float argument where an integer was expected.
4823 These functions and methods now raise TypeError instead. The majority of the
4824 effects of this change are in the extension modules, but some core functions
4825 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4826 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004839- Issue #1811: Improve accuracy and cross-platform consistency for true division
4840 of integers: the result of a/b is now correctly rounded for ints a and b (at
4841 least on IEEE 754 platforms), and in particular does not depend on the
4842 internal representation of a long.

4850
Georg Brandlba83f822010-03-14 09:50:54 +00004851 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004990- Issue #3382: 'F' formatting for float and complex now convert the result to
4991 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4992 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004993
Georg Brandlba83f822010-03-14 09:50:54 +00004994- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4995 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004996
Georg Brandlba83f822010-03-14 09:50:54 +00004997- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4998 1e-100 used to raise OverflowError, but now gives the requested 120
4999 significant digits instead.

5006 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005007
Georg Brandlba83f822010-03-14 09:50:54 +00005008- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5009 decimal string that's guaranteed to round back to x under correct rounding
5010 (with round-half-to-even rounding mode). Previously it gave a string based on
5011 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5012 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5013 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005014
Georg Brandlba83f822010-03-14 09:50:54 +00005015- Issue #7117: On almost all platforms: float-to-string and string-to-float
5016 conversions within Python are now correctly rounded. Places these conversions
5017 occur include: str for floats and complex numbers; the float and complex
5018 constructors; old-style and new-style numeric formatting; serialization and
5019 deserialization of floats and complex numbers using marshal, pickle and json;
5020 parsing of float and imaginary literals in Python code; Decimal-to-float
5021 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005022
Georg Brandlba83f822010-03-14 09:50:54 +00005023 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5024 providing correctly-rounded strtod and dtoa C functions. This code is
5025 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5026 the C compiler. There may be a small number of platforms on which correct
5027 operation of this code cannot be guaranteed, so the code is not used: notably,
5028 this applies to platforms where the C double format is not IEEE 754 binary64,
5029 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5030 and Python's configure script is unable to determine how to change the FPU
5031 precision. On these platforms conversions use the platform strtod and dtoa,
5032 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005034- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5035 uses the correctly-rounded string <-> float conversions described above (when
5036 available), and so produces correctly rounded results that will display nicely
5037 under the float repr. There are two related small changes: (1) round now
5038 accepts any class with an ``__index__()`` method for its second argument (but
5039 no longer accepts floats for the second argument), and (2) an excessively
5040 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5041 raises an exception.

5044
Georg Brandlba83f822010-03-14 09:50:54 +00005045- Fix several issues with ``compile()``. The input can now contain Windows and

5190 but with at least one decimal point and with a default precision
5191 of 12. Previously, the behavior the same but with a default precision of 6.
5192 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandlba83f822010-03-14 09:50:54 +00005203- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
5204 '.5')`` now produces a sensible result.
Eric Smith9139cc62009-04-30 00:58:58 +00005205
Georg Brandlba83f822010-03-14 09:50:54 +00005206- Issue #5864: Fix empty format code formatting for floats so that it never
5207 gives more than the requested number of significant digits.
Mark Dickinson92fcc9c2009-04-29 20:41:00 +00005208
Georg Brandlba83f822010-03-14 09:50:54 +00005209- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new

5213 not their own uppercase.
Martin v. Löwis99f27792009-04-26 00:53:18 +00005214
Eric Smith068f0652009-04-25 21:40:15 +00005215- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
5216 _PyOS_double_to_string or PyOS_double_to_string.
5217
Benjamin Peterson5083dc52009-04-25 00:41:22 +00005218- Issue #5283: Setting __class__ in __del__ caused a segfault.
5219
Georg Brandlba83f822010-03-14 09:50:54 +00005220- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
5221 nans, infs or negative zeros.

Georg Brandlba83f822010-03-14 09:50:54 +00005229- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
5230 type code and we have an exponent.
Eric Smithaca19e62009-04-22 13:29:05 +00005231
Georg Brandlba83f822010-03-14 09:50:54 +00005232- Issue #3166: Make long -> float (and int -> float) conversions correctly

Georg Brandlba83f822010-03-14 09:50:54 +00005238- Issue #1869: Fix a couple of minor round() issues. ``round(5e15+1)`` was
5239 giving 5e15+2; ``round(-0.0)`` was losing the sign of the zero.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005258- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005259 untrackable objects are not tracked by the garbage collector. This can reduce
5260 the size of collections and therefore the garbage collection overhead on
5261 long-running programs, depending on their particular use of datatypes.
Antoine Pitrouf8387af2009-03-23 18:41:45 +00005262
Georg Brandlba83f822010-03-14 09:50:54 +00005263- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its

5265 150% faster.
Mark Dickinson0b666bf2009-03-23 18:25:13 +00005266
Georg Brandlba83f822010-03-14 09:50:54 +00005267- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
5268 internal representation of integers, for performance reasons. Base 2**30 is
5269 enabled by default on 64-bit machines. Add --enable-big-digits option to
5270 configure, which overrides the default. Add sys.long_info structseq to
5271 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00005272
Benjamin Peterson6ffe8522009-03-18 20:52:15 +00005273- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
5274 result traceback.__members__ no longer exists.)
5275
Georg Brandlba83f822010-03-14 09:50:54 +00005276- Issue #4474: PyUnicode_FromWideChar now converts characters outside the BMP to
5277 surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE)
5278 == 2.
Mark Dickinson6b265f12009-03-18 16:07:26 +00005279
Georg Brandlba83f822010-03-14 09:50:54 +00005280- Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{}
5281 {}'.format(1, 2) == '1 2'``.
Eric Smith6f42edb2009-03-14 11:57:26 +00005282
Georg Brandlba83f822010-03-14 09:50:54 +00005283- Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a
Brett Cannon6c4cff02009-03-11 04:51:06 +00005284 requirement. Means the DeprecationWarning from Python 2.6 can go away.
5285
Georg Brandlba83f822010-03-14 09:50:54 +00005286- Issue #5247: Improve error message when unknown format codes are used when
5287 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00005288
Georg Brandlba83f822010-03-14 09:50:54 +00005289- Running Python with the -3 option now also warns about classic division for
5290 ints and longs.
Raymond Hettinger08259e82009-02-18 23:10:19 +00005291
Georg Brandlba83f822010-03-14 09:50:54 +00005292- Issue #5260: Long integers now consume less memory: average saving is 2 bytes
5293 per long on a 32-bit system and 6 bytes per long on a 64-bit system.
Mark Dickinson2ffb26f2009-02-15 10:13:41 +00005294
Antoine Pitrou76a4b892009-02-13 13:52:33 +00005295- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
5296 rotating the object pointer by 4 bits to the right.
5297
Georg Brandlba83f822010-03-14 09:50:54 +00005298- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now
5299 forces its argument to double before testing for infinity.
Mark Dickinsonc97c9092009-02-09 14:18:43 +00005300
Benjamin Petersone18ef192009-01-20 14:21:16 +00005301- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
5302
Georg Brandl29c6a282009-04-05 20:23:13 +00005303- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00005304 were suppressing all exceptions. These include list(), filter(), map(),
5305 zip(), and bytearray().
5306
Benjamin Peterson596d3062009-01-19 15:42:23 +00005307- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
5308 functions.
5309
Benjamin Peterson5848d1f2009-01-19 00:08:08 +00005310- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
5311 OSError.
5312
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +00005313- Issue #4807: Port the _winreg module to Windows CE.
5314
Georg Brandlba83f822010-03-14 09:50:54 +00005315- Issue #4935: The overflow checking code in the expandtabs() method common to
5316 str, bytes and bytearray could be optimized away by the compiler, letting the
5317 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00005318
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00005319- Issue #3720: Fix a crash when an iterator modifies its class and removes its
5320 __next__ method.
5321

5325
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00005326- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
5327 collecting the oldest generation) so that allocating lots of objects without
5328 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00005329 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00005330 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

5333
Georg Brandlba83f822010-03-14 09:50:54 +00005334- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5335 existing .py counterpart, override the co_filename attributes of all code
5336 objects if the original filename is obsolete (which can happen if the file has
5337 been renamed, moved, or if it is accessed through different paths). Patch by
5338 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00005339
Georg Brandlba83f822010-03-14 09:50:54 +00005340- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00005342- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
5343 file with `str' filename on Windows.
5344
Antoine Pitrouaa687902009-01-01 14:11:22 +00005345- Issue #3680: Reference cycles created through a dict, set or deque iterator
5346 did not get collected.
5347
Georg Brandlba83f822010-03-14 09:50:54 +00005348- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
5349 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00005350
Benjamin Peterson7af65562008-12-29 17:56:58 +00005351- Issue #4764: With io.open, IOError.filename is set when trying to open a
5352 directory on POSIX systems.
5353
Benjamin Petersonfe231b02008-12-29 17:47:42 +00005354- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
5355 systems.
5356
Georg Brandl6425a2f2008-12-28 11:54:53 +00005357- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00005358 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00005359
Skip Montanarof205c132008-12-23 03:30:15 +00005360- Added test case to ensure attempts to read from a file opened for writing
5361 fail.
5362
Georg Brandlba83f822010-03-14 09:50:54 +00005363- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
5364 elapsed times, not only when some objects are uncollectable/unreachable.
5365 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00005366

Georg Brandlba83f822010-03-14 09:50:54 +00005377- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5378 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5379 instances. On a typical machine this saves 3 bytes of memory (on average) per
5380 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00005381
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005382- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
5383 interpreter to abort ("Fatal Python error: Could not reset the stack!")
5384 instead of throwing a MemoryError.
5385
Georg Brandlba83f822010-03-14 09:50:54 +00005386- Issue #3689: The list reversed iterator now supports __length_hint__ instead
5387 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00005388
Benjamin Petersonc078f922008-11-21 22:27:24 +00005389- Issue #4367: Python would segfault during compiling when the unicodedata
5390 module couldn't be imported and \N escapes were present.
5391
Georg Brandlba83f822010-03-14 09:50:54 +00005392- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5393 file objects with closefd=False. The file descriptor is still kept open but
5394 the file object behaves like a closed file. The ``FileIO`` object also got a
5395 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00005396
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00005397- Issue #4348: Some bytearray methods returned that didn't cause any change to
5398 the bytearray, returned the same bytearray instead of a copy.
5399
Georg Brandlba83f822010-03-14 09:50:54 +00005400- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

5403
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00005404- Issue #4048: The parser module now correctly validates relative imports.
5405
Benjamin Petersondcee09d2008-10-31 02:16:05 +00005406- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

5413 __future__ import didn't work.
5414
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005415- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00005416 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00005417
Georg Brandlba83f822010-03-14 09:50:54 +00005418- On windows, ``os.chdir()`` given unicode was not working if
5419 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5420 this code path is really executed because I cannot move to such directory on
5421 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00005422
Georg Brandlba83f822010-03-14 09:50:54 +00005423- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5424 element is temporarily replaced with an equivalent frozenset. But the
5425 eventual KeyError would always report the empty ``frozenset()`` as the missing
5426 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00005427

6823-----------------
6824
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006825- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6826
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006827- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6828 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6829 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6830 ``printf`` function, whereas PyString_FromFormat has an independent
6831 implementation and uses "%zd" on all platforms for size_t values.
6832 This makes a difference on win64, where ``printf`` needs "%Id" to display
6833 64bit values.
6834
Benjamin Peterson97179b02008-09-09 20:55:01 +00006835- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6836 error.
6837
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006838- Issue #3777: long() applied to a float object now always return a long
6839 object; previously an int would be returned for small values. the __long__
6840 method is allowed to return either an int or a long, but the behaviour of
6841 float objects should not change to respect backward compatibility.
6842
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006843- Issue #3751: str.rpartition would perform a left-partition when called with
6844 a unicode argument.
6845
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006846- Issue #3683: Fix compilation when --without-threads is given.
6847
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006848- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00006849 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006850 was correctly parsed but parsing of subsequent arguments failed.
6851
Vinay Sajip35e3b032008-09-01 14:33:59 +00006852- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006853 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6854 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6855 when given a tuple of classes as second argument, were looking up
6856 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6857 type object.
6858
Neal Norwitz18aa3882008-08-24 05:04:52 +00006859- Fix crashes on memory allocation failure found with failmalloc.
6860
6861- Fix memory leaks found with valgrind and update suppressions file.
6862
6863- Fix compiler warnings in opt mode which would lead to invalid memory reads.
6864
6865- Fix problem using wrong name in decimal module reported by pychecker.
6866
Christian Heimes7d4c3172008-08-22 19:47:25 +00006867- Silenced another compiler warning about a used but not defined
6868 function 'stringlib_contains_obj'.
6869
Benjamin Peterson712ee922008-08-24 18:10:20 +00006870- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
6871 ``__delslice__``.
6872
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00006873- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
6874 library targets in the Makefile.
6875
Gregory P. Smith980b99b2008-09-07 05:15:18 +00006876- Issue #1204: The configure script now tests for additional libraries
6877 that may be required when linking against readline. This fixes issues
6878 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
6879
Benjamin Peterson14cb6bc2008-08-26 17:08:40 +00006880C-API
6881-----
6882

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00006888- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
6889 stack usage in the case of deeply nested objects.
6890

Nick Coghland2e09382008-09-11 12:11:06 +00006901- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00006902 return a list or None rather than a custom object.
6903
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00006904- Issue #1638033: Cookie.Morsel gained the httponly attribute.
6905
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00006906- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006928 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6929 for catch_warnings() also led to an improvement in the raising of a
6930 DeprecationWarning related to warnings.warn_explicit().
6931
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006932- The deprecation warnings for the old camelCase threading API were removed.

6954
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006955- Issue #2975: When compiling several extension modules with Visual Studio 2008
6956 from the same python interpreter, some environment variables would grow
6957 without limit.
6958
Benjamin Peterson37346b22008-08-23 20:27:43 +00006959- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6960 exploitation of poor argument checking.
6961
Gerhard Häringef2276b2008-09-12 13:54:06 +00006962- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007000
7001Core and Builtins
7002-----------------
7003
Guido van Rossumf8402962008-08-20 15:01:50 +00007004- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7005 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7006 extensions do not automatically benefit from the class attribute
7007 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7008 to their tp_flags field if they care. This is a backwards
7009 compatibility feature; in 3.0, all types will use the cache by
7010 default.
7011
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007012- Keyword arguments can now follow starred arguments. (``f(a, *args,
7013 keyword=23)`` is now valid syntax.)
7014
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007015- ctypes function pointers that are COM methods have a boolean True
7016 value again.
7017
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007018- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7019 by denying s# to parse objects that have a releasebuffer procedure,
7020 and introducing s*.
7021
Georg Brandl1e13ea92008-08-11 09:07:59 +00007022- Issue #3537: Fix an assertion failure when an empty but presized dict
7023 object was stored in the freelist.
7024
Mark Dickinsonb6467572008-08-04 21:30:09 +00007025- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7026 ValueError consistently across platforms.
7027
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007028- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7029 (64bit Unix, for example), unichr() would truncate its argument and return
7030 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7031
Neal Norwitze7d8be82008-07-31 17:17:14 +00007032- Apply security patches from Apple.
7033
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007034- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7035 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7036
Antoine Pitrou92f82162008-07-25 22:22:08 +00007037- Issue #1819: function calls with several named parameters are now on
7038 average 35% faster (as measured by pybench).
7039
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007040- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7041 the python debugger steps into a class statement: the free variables (local
7042 variables defined in an outer scope) would be deleted from the outer scope.
7043
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007044- Issue #2620: Overflow checking when allocating or reallocating memory
7045 was not always being done properly in some python types and extension
7046 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7047 all been updated to perform better checks and places in the code that
7048 would previously leak memory on the error path when such an allocation
7049 failed have been fixed.

7052-------
7053
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007054- Issue #3612: Added some missing basic types in ctypes.wintypes.
7055
Benjamin Petersone977ad42008-08-20 01:42:01 +00007056- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7057 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7058
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007059- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7060 version reported by these tools does not necessarily follow the python
7061 version numbering scheme, so the module is less strict when parsing it.
7062
Nick Coghlanf70385a2008-08-18 12:42:46 +00007063- Issue #2235: Added Py3k warnings for types which will become unhashable
7064 under the stricter __hash__ inheritance rules in 3.0. Several types
7065 which did not meet the rules for hash invariants and were already
7066 unhashable in 3.0 have now been explicitly flagged as unhashable in
7067 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7068 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7069
Brett Cannon88f801d2008-08-18 00:46:22 +00007070- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7071 imported into the module but exposed as part of the module's API.
7072
Brett Cannon7b96f072008-08-18 00:41:11 +00007073- Remove an unneeded import of abc.ABCMeta from 'inspect'.

7078
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007079- Issue #3575: Incremental decoder's decode function now takes bytearray
7080 by using 's*' instead of 't#'.
7081
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007082- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007083 fails unicode conversion on 2nd parameter. (windows only)
7084
Georg Brandl222e2082010-08-01 22:27:39 +00007085- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007086 in a redirect.
7087
Brett Cannonabe423e2008-08-16 21:47:07 +00007088- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007089 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007090
Facundo Batistaeb90b782008-08-16 14:44:07 +00007091- Issue #2776: fixed small issue when handling an URL with double slash
7092 after a 302 response in the case of not going through a proxy.
7093
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007094- Issue #2676: in the email package, content-type parsing was hanging on
7095 pathological input because of quadratic or exponential behaviour of a
7096 regular expression.
7097
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007098- Issue #3476: binary buffered reading through the new "io" library is now
7099 thread-safe.
7100
Brett Cannonbf3157b2008-08-14 05:00:03 +00007101- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7102 since mimetools itself is deprecated. Because modules are cached, all
7103 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7104

Antoine Pitroude781a42008-08-09 12:43:23 +00007139 asking for a specific length. This problem only affected files opened

7183
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007184- Issue #643841: The language reference now provides more detailed

7197
Georg Brandl3e483f62008-07-16 22:57:41 +00007198- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7199 its methods now allow for items objects that can be converted to
7200 an integer using operator.index().
7201
Mark Dickinson64b7e502008-07-16 09:40:03 +00007202- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7203 produced a ValueError instead of giving the correct float.
7204
Eric Smitha5fa5a22008-07-16 00:11:49 +00007205- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7206 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7207
Mark Dickinson7103aa42008-07-15 19:08:33 +00007208- Issue #3008: the float type has a new instance method 'float.hex'
7209 and a new class method 'float.fromhex' to convert floating-point
7210 numbers to and from hexadecimal strings, respectively.
7211
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007212- Issue #2235: __hash__ is once again inherited by default. To allow
7213 collections.Hashable to remain meaningful in the presence of the
7214 default hash implementation (object.__hash__), it is now possible
7215 to explicit block inheritance of hash by setting __hash__=None at
7216 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7217 level.
7218
Nick Coghlanb028f502008-07-13 14:52:36 +00007219- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7220 the parent module cannot be found while performing an absolute import.
7221 This means that an incorrectly defined __package__ attribute will
7222 now only prevent relative imports in that module rather than causing
7223 all imports from that module to fail.
7224
Nick Coghlan14ff9942008-07-08 14:21:42 +00007225- Issue #2517: Allow unicode messages in Exceptions again by correctly

7235 another thread's dictionary.
7236
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007237- Issue #3004: Minor change to slice.indices(): the start and stop
7238 arguments are now treated identically, making the behaviour easier
7239 to describe and understand. For example, slice(None, -10,
7240 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7241 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7242 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007244- Issue #3219: Calling a function with repeated keyword arguments,
7245 f(a=2, a=23), would not cause a syntax error. This was a regression
7246 from 2.4 caused by the switch to the new compiler.

7285 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007286 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007287 content-length. The problem had been corrected in the 2.4 branch, but never

Benjamin Peterson23681932008-05-12 21:42:13 +00007671
Vinay Sajip9828b7e2008-06-17 11:04:02 +00007672- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007673 environment to control the '-arch' flags that are used to build
7674 an extension. This was added for compatibility with Apple's build
7675 of Python.
7676
7677- The bundled OSX-specific copy of libbffi is now in sync with the version
7678 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
7679
Georg Brandl25c34082008-08-18 23:09:49 +00007680- The threading module gained aliases for names that will be removed in the
7681 3.x series.

7689
Brett Cannonb61d8012008-05-11 23:39:04 +00007690- ``Lib/lib-old`` is now added to sys.path.
7691
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007692- On MacOS X it is now possible to install the framework in 64-bit
7693 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007694 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007695
7696 This is controlled by the configure argument ``--with-universal-archs``:
7697
7698 - ``--with-universal-archs=all``: install 4-way universal
7699
7700 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7701
7702 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7703
7704 This option should be used in combination with ``--enable-universalsdk=``.
7705
7706 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

7713- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00007714
7715- The PyString functions have been renamed to PyBytes. A batch of
7716 defines were added so that the linker still sees the original
7717 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007755- Issue #1631171: Re-implement the 'warnings' module in C (the
7756 original Python code has been kept as backup). This will allow for
7757 using the 'warning's machinery in such places as the parser where
7758 use of pure Python code is not possible. Both the ``showarning()``
7759 and ``formatwarning()`` gain an optional 'line' argument which is
7760 not called by default for backwards-compatibility reasons. Setting
7761 ``warnings.showwarning()`` to an implementation that lacks support
7762 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00007787- The getpass module has been improved on Unix. It now uses /dev/tty
7788 by default and uses stderr instead of stdout. A GetPassWarning is
7789 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007804- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007805 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007825- Issue #2550: The approach used by client/server code for obtaining
7826 ports to listen on in network-oriented tests has been refined in an
7827 effort to facilitate running multiple instances of the entire
7828 regression test suite in parallel without issue.
7829 test_support.bind_port() has been fixed such that it will always
7830 return a unique port -- which wasn't always the case with the
7831 previous implementation, especially if socket options had been set
7832 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7833 new implementation of bind_port() will actually raise an exception
7834 if it is passed an AF_INET/SOCK_STREAM socket with either the
7835 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7836 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7837 the socket it's been passed. This currently only applies to
7838 Windows. This option prevents any other sockets from binding to the
7839 host/port we've bound to, thus removing the possibility of the
7840 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7841 when a second SOCK_STREAM socket binds and accepts to a host/port
7842 that's already been bound by another socket. The optional preferred
7843 port parameter to bind_port() has been removed. Under no
7844 circumstances should tests be hard coding ports!
7845
7846 test_support.find_unused_port() has also been introduced, which will
7847 pass a temporary socket object to bind_port() in order to obtain an
7848 unused port. The temporary socket object is then closed and
7849 deleted, and the port is returned. This method should only be used
7850 for obtaining an unused port in order to pass to an external program
7851 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7852 a parameter to a server-oriented class that doesn't give you direct
7853 access to the underlying socket used.
7854
7855 Finally, test_support.HOST has been introduced, which should be used
7856 for the host argument of any relevant socket calls (i.e. bind and
7857 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007858
7859 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007860 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007861 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7862 test_asynchat and test_socket_ssl.
7863
Georg Brandl3ee81df2008-05-17 18:14:43 +00007864 It is now possible for multiple instances of the regression test
7865 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008144- Added the future_builtins module, which contains hex() and oct().
8145 These are the PEP 3127 version of these functions, designed to be
8146 compatible with the hex() and oct() builtins from Python 3.0. They
8147 differ slightly in their output formats from the existing, unchanged
8148 Python 2.6 builtins. The expected usage of the future_builtins
8149 module is:
8150 from future_builtins import hex, oct
8151
Eric Smith7ef40bf2008-02-20 23:34:22 +00008152- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8153 exponents for exponents with absolute value < 100. Follows C99
8154 standard. This is a change on Windows, which would use 3 digits.
8155 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8156 so that any alterations it does to the resulting string will be
8157 available in stringlib/formatter.h (for float.__format__).
8158
Eric Smith5a3c1352008-02-19 13:21:56 +00008159- Implemented PEP 3101, Advanced String Formatting. This adds a new
8160 builtin format(); a format() method for str and unicode; a
8161 __format__() method to object, str, unicode, int, long, float, and
8162 datetime; the class string.Formatter; and the C API
8163 PyObject_Format().
8164
Georg Brandl3ee81df2008-05-17 18:14:43 +00008165- Fixed several potential crashes, all caused by specially crafted
8166 __del__ methods exploiting objects in temporarily inconsistent
8167 state.

8178 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008179
Georg Brandl3ee81df2008-05-17 18:14:43 +00008180- Issue #2045: Fix an infinite recursion triggered when printing a
8181 subclass of collections.defaultdict, if its default_factory is set
8182 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008183
Christian Heimesf75dbef2008-02-08 00:11:31 +00008184- Fixed a minor memory leak in dictobject.c. The content of the free
8185 list was not freed on interpreter shutdown.
8186
Georg Brandl21e99f42010-03-07 15:23:59 +00008187- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008188 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008189
Georg Brandl3ee81df2008-05-17 18:14:43 +00008190- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8191 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008192 to compact the internal free lists of pre-allocted ints and floats.
8193
Georg Brandl3ee81df2008-05-17 18:14:43 +00008194- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8195 calls. Python expected the return type int but the fork familie
8196 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008197
Georg Brandl3ee81df2008-05-17 18:14:43 +00008198- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8199 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008200
Georg Brandl3ee81df2008-05-17 18:14:43 +00008201- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8202 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008203
Georg Brandl3ee81df2008-05-17 18:14:43 +00008204- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8205 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00008207- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8208 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008209
Georg Brandl3ee81df2008-05-17 18:14:43 +00008210- Patch #1473257: generator objects gain a gi_code attribute. This is
8211 the same object as the func_code attribute of the function that
8212 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008213
Georg Brandl3ee81df2008-05-17 18:14:43 +00008214- Issue #1920: "while 0" statements were completely removed by the
8215 compiler, even in the presence of an "else" clause, which is
8216 supposed to be run when the condition is false. Now the compiler
8217 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008218
Guido van Rossumeead05f2008-01-24 18:21:02 +00008219- A few crashers fixed: weakref_in_del.py (issue #1377858);
8220 loosing_dict_ref.py (issue #1303614, test67.py);
8221 borrowed_ref_[34].py (not in tracker).
8222
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008223- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008224 suppressed while an extension is loaded by calling SetErrorMode in
8225 dynload_win.c. The error is still reported properly.
8226
Georg Brandl3ee81df2008-05-17 18:14:43 +00008227- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008228 several extension methods and modules do not work without unicode
8229 support.
8230
Georg Brandl26543b12008-01-21 18:36:51 +00008231- Issue #1882: when compiling code from a string, encoding cookies in the
8232 second line of code were not always recognized correctly.
8233
Georg Brandl14404b62008-01-19 19:27:05 +00008234- Issue #1679: "0x" was taken as a valid integer literal.
8235
Georg Brandl6caad7d2008-01-26 14:19:22 +00008236- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008237 added.
8238
Christian Heimesc94e2b52008-01-14 04:13:37 +00008239- sys.float_info / PyFloat_GetInfo: The floating point information
8240 object was converted from a dict to a specialized structseq object.
8241
Georg Brandl3ee81df2008-05-17 18:14:43 +00008242- Patch #1816: Added sys.flags structseq. It exposes the status of
8243 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008244
Georg Brandl3ee81df2008-05-17 18:14:43 +00008245- Objects/structseq.c: Implemented new structseq representation. The
8246 patch makes structseqs (e.g. the return value of os.stat) more
8247 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008248
Georg Brandl3ee81df2008-05-17 18:14:43 +00008249- Patch #1700288: added a type attribute cache that caches method
8250 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008251
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008252- Bug #1776: __import__() no longer accepts filenames on any platform.
8253 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008254
Georg Brandlaed6c662008-01-07 17:25:53 +00008255- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008257- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8258 envvar and sys.dont_write_bytecode attribute. All these can be set
8259 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008260
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- Improve some exception messages when Windows fails to load an
8262 extension module. Now we get for example '%1 is not a valid Win32
8263 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008264

8268 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008269
Christian Heimes0a8143f2007-12-18 23:22:54 +00008270- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008271 and INF. float("nan"), float("inf") and float("-inf") now work on
8272 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008273
Georg Brandl3ee81df2008-05-17 18:14:43 +00008274- Compiler now generates simpler and faster code for dictionary
8275 literals. The oparg for BUILD_MAP now indicates an estimated
8276 dictionary size. There is a new opcode, STORE_MAP, for adding
8277 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008306- Patch #1739468: Directories and zipfiles containing a __main__.py
8307 file can now be directly executed by passing their name to the
8308 interpreter. The directory/zipfile is automatically inserted as the
8309 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008311- Issue #1265: Fix a problem with sys.settrace, if the tracing
8312 function uses a generator expression when at the same time the
8313 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008314
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008315- sets and frozensets now have an isdisjoint() method.
8316
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008317- optimize the performance of builtin.sum().
8318
Neal Norwitz44f326e2007-10-05 05:29:17 +00008319- Fix warnings found by the new version of the Coverity checker.
8320
Georg Brandl21e99f42010-03-07 15:23:59 +00008321- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008322 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8323 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008324
Georg Brandl3ee81df2008-05-17 18:14:43 +00008325- Issue #1686386: Tuple's tp_repr did not take into account the
8326 possibility of having a self-referential tuple, which is possible
8327 from C code. Nor did object's tp_str consider that a type's tp_str
8328 could do something that could lead to an inifinite recursion.
8329 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8330 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008331
Georg Brandl3ee81df2008-05-17 18:14:43 +00008332- Issue #1164: It was possible to trigger deadlock when using the
8333 'print' statement to write to a file since the GIL was not released
8334 as needed. Now PyObject_Print() does the right thing along with
8335 various tp_print implementations of the built-in types and those in
8336 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008337
Georg Brandl3ee81df2008-05-17 18:14:43 +00008338- Issue #1147: Exceptions were directly allowing string exceptions in
8339 their throw() method even though string exceptions no longer
8340 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008341
Georg Brandl3ee81df2008-05-17 18:14:43 +00008342- Issue #1096: Prevent a segfault from getting the repr of a very
8343 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008344
Brett Cannon1e534b52007-09-07 04:18:30 +00008345- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008346 PyObject_Call() never calling back out to Python code to trigger
8347 recursion depth updates/checks. Required the creation of a static
8348 RuntimeError instance in case normalizing an exception put the
8349 recursion check value past its limit. Fixes crashers
8350 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008351

Neal Norwitz0ac60192007-05-27 04:08:54 +00008365- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008366 __*__ attributes. (Some already existed, e.g., __doc__ and
8367 __name__.)

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008369- Add -3 option to the interpreter to warn about features that are
8370 deprecated and will be changed/removed in Python 3.0.
8371
Georg Brandl2134e752007-05-21 20:34:16 +00008372- Patch #1686487: you can now pass any mapping after '**' in function
8373 calls.
8374
Collin Winter62903052007-05-18 23:11:24 +00008375- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008376 "except E as target:". This is to provide forwards compatibility
8377 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008384- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008385 setting a plain string, ie don't expand to single letter identifiers.
8386
Raymond Hettinger13936692007-04-11 18:40:58 +00008387- Request #1191699: Slices can now be pickled.
8388
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008389- Request #1193128: str.translate() now allows a None argument for
8390 translations that only remove characters without re-mapping the
8391 remaining characters.
8392
Georg Brandl5cb76c12007-03-21 09:00:39 +00008393- Patch #1682205: a TypeError while unpacking an iterable is no longer
8394 masked by a generic one with the message "unpack non-sequence".
8395
Neal Norwitzaa754b72007-03-21 06:39:48 +00008396- Remove unused file Python/fmod.c.
8397
Guido van Rossum143b5642007-03-23 04:58:42 +00008398- Bug #1683368: The object.__init__() and object.__new__() methods are
8399 now stricter in rejecting excess arguments. The only time when
8400 either allows excess arguments is when it is not overridden and the
8401 other one is. For backwards compatibility, when both are
8402 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008403 warning later). Also, type.__init__() insists on the same signature
8404 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008406- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8407 object to complex using its __complex__() method before falling back
8408 to the __float__() method. Therefore, the functions in the cmath
8409 module now can operate on objects that define a __complex__()
8410 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009477 time so that opening a database previously created with the DB_DUP
9478 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9479 opens. Specifically: dictionary assignment to a DB object will
9480 replace all values for a given key when the database allows
9481 duplicate values. DB users should use DB.put(k, v) when they want
9482 to store duplicates; not DB[k] = v.

9489 characters with ASCII value less than 32. Also, it correctly quotes
9490 dots only if they occur on a single line, as opposed to the previous
9491 behavior of quoting dots if they are the second character of any
9492 line.
