Ned Deily18fae3f2013-01-31 01:24:55 -0800686- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
687 In particular, fix extension module build failures when trying to use
688 32-bit-only installer Pythons on systems with Xcode 4 (currently
689 OS X 10.8, 10.7, and optionally 10.6).
690 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
691 * Since Xcode 4 removes ppc support, extension module builds now
692 check for ppc compiler support and by default remove ppc and
693 ppc64 archs when they are not available.
694 * Extension module builds now revert to using system installed
695 headers and libs (/usr and /System/Library) if the SDK used
696 to build the interpreter is not installed or has moved.
697 * Try to avoid building extension modules with deprecated
698 and problematic Apple llvm-gcc compiler. If original compiler
699 is not available, use clang instead by default.

923 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100924 compiler optimizing the check away. Also fix similar overflow checks
925 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001001- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1002 Distutils-based packages with C extension modules may fail because
1003 Apple has removed gcc-4.2, the version used to build python.org
1004 64-bit/32-bit Pythons. If the user does not explicitly override
1005 the default C compiler by setting the CC environment variable,
1006 Distutils will now attempt to compile extension modules with clang
1007 if gcc-4.2 is required but not found. Also as a convenience, if
1008 the user does explicitly set CC, substitute its value as the default
1009 compiler in the Distutils LDSHARED configuration variable for OS X.
1010 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1011 SDK, neither of which are available in Xcode 4. This change does not
1012 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001285- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1286 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1287 interpreter process. This could cause failures in non-Distutils subprocesses
1288 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001289 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001290 deployment target only in the environment of each build subprocess. It is
1291 still possible to globally override the default by setting
1292 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1293 greater or equal to the default value, the value with which the interpreter
1294 was built.

1321
Barry Warsawc5643282011-07-19 17:06:30 -04001322- sys.setcheckinterval() now updates the current ticker count as well as
1323 updating the check interval, so if the user decreases the check interval,
1324 the ticker doesn't have to wind down to zero from the old starting point
1325 before the new interval takes effect. And if the user increases the
1326 interval, it makes sure the new limit takes effect right away rather have an
1327 early task switch before recognizing the new interval.

2279 This prevents user-created self-referencing ordered dictionaries from
2280 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002742- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2743 start byte and the continuation byte(s) are now considered invalid, instead
2744 of the number of bytes specified by the start byte.
2745 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2746 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2747 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002756- Issue #8748: Fix two issues with comparisons between complex and integer
2757 objects. (1) The comparison could incorrectly return True in some cases
2758 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2759 (2) The comparison raised an OverflowError for large integers, leading
2760 to unpredictable exceptions when combining integers and complex objects
2761 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00002763- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00002900- Issue #1533: Fix inconsistency in range function argument processing: any
2901 non-float non-integer argument is now converted to an integer (if possible)
2902 using its __int__ method. Previously, only small arguments were treated this
2903 way; larger arguments (those whose __int__ was outside the range of a C long)
2904 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00002912 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00002913 benefit compared to the dynamic memory allocation fallback. Patch by
2914 Charles-François Natali.

2939 messages when accessing undefined class attributes because of the cheap
2940 inheritance with the underlying socket object. The cheap inheritance has been
2941 deprecated.
Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +00002942

Georg Brandlfee0f442010-05-22 21:26:21 +00002954- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2955 operation raises multiple signals and more than one of those signals is
2956 trapped, the specification determines the order in which the signals should be
2957 handled. In many cases this order wasn't being followed, leading to the wrong
2958 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00002959

3127
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003128- Issue #7301: Add environment variable $PYTHONWARNINGS.
3129
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003130- Issue #8329: Don't return the same lists from select.select when no fds are
3131 changed.
3132
Georg Brandlfee0f442010-05-22 21:26:21 +00003133- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003134 on 64-bit machines. The shift count for either left or right shift is
3135 permitted to be up to sys.maxsize.
3136
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003137- Ensure that tokenization of identifiers is not affected by locale.
3138
Georg Brandlfee0f442010-05-22 21:26:21 +00003139- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003140
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003141- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3142
Georg Brandlfee0f442010-05-22 21:26:21 +00003143- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3144 with a non-empty format string. This is an effort to future-proof user
3145 code. If a derived class does not currently implement __format__ but later
3146 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003147 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003148 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003149
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003150- Issue #8268: Old-style classes (not just instances) now support weak
3151 references.
3152
Georg Brandlfee0f442010-05-22 21:26:21 +00003153- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
3154 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00003155
Victor Stinnerc7790ed2010-03-22 12:36:28 +00003156- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00003157
Benjamin Peterson96545892010-03-21 20:21:00 +00003158- Issue #6474: Make error message from passing an inadequate number of keyword
3159 arguments to a function correct.
3160
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003161- Issue #8164: Don't allow lambda functions to have a docstring.
3162
Victor Stinner66644262010-03-10 22:30:19 +00003163- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003164 (SIGINT). If an error occurs while importing the site module, the error is
3165 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003166 module.
3167
Collin Winter001a3952010-03-18 21:54:01 +00003168- Code objects now support weak references.

3171-------
3172
R. David Murray661303f2010-04-13 20:57:40 +00003173- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
3174
Antoine Pitrouf9de5342010-04-05 21:35:07 +00003175- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00003176 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
3177 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00003178
Benjamin Peterson76a23c12010-04-04 23:23:22 +00003179- Issue #8310: Allow dis to examine new style classes.
3180
Georg Brandlfee0f442010-05-22 21:26:21 +00003181- Issue #8257: The Decimal construct now accepts a float instance directly,
3182 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003183
3184 >>> Decimal(1.1)
3185 Decimal('1.100000000000000088817841970012523233890533447265625')
3186
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003187- collections.Counter() now supports a subtract() method.
3188
Georg Brandlfee0f442010-05-22 21:26:21 +00003189- The functools module now has a total_ordering() class decorator to simplify
3190 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003191
Georg Brandlfee0f442010-05-22 21:26:21 +00003192- The functools module also adds cmp_to_key() as a tool to transition old-style
3193 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003194
Georg Brandlfee0f442010-05-22 21:26:21 +00003195- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3196 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003197
Georg Brandlfee0f442010-05-22 21:26:21 +00003198- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3199 InvalidOperation instead of returning False. (Comparisons involving a quiet
3200 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3201 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003202
Georg Brandlfee0f442010-05-22 21:26:21 +00003203- Issue #2531: Comparison operations between floats and Decimal instances now
3204 return a result based on the numeric values of the operands; previously they
3205 returned an arbitrary result based on the relative ordering of id(float) and
3206 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003207
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003208- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003209 argument `-` which tells it to read files to compile from stdin. Each line is
3210 read on demand and the named file is compiled immediately. (Original patch by
3211 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003212
Georg Brandlfee0f442010-05-22 21:26:21 +00003213- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3214 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003216- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3217 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003218 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003219
Georg Brandlfee0f442010-05-22 21:26:21 +00003220- Comparisons using one of <, <=, >, >= between a complex instance and a
3221 Fractions instance now raise TypeError instead of returning True/False. This
3222 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3223 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003224

3233
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003234- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003235 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3236 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003237
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003238- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3239 deprecated.
3240
Georg Brandlfee0f442010-05-22 21:26:21 +00003241- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3242 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00003243

3248 existing at the same time, causing a Unicode error when configuration code
3249 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00003250
Georg Brandlfee0f442010-05-22 21:26:21 +00003251- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003278- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003279 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3280 log file to compute the next rollover time. If the log file does not exist,
3281 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003282

3290
Georg Brandlba83f822010-03-14 09:50:54 +00003291- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3292 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3293 This is a behavior change, so email's minor version number is now bumped, to
3294 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003322- Issue #8300: When passing a non-integer argument to struct.pack with any
3323 integer format code, struct.pack first attempts to convert the non-integer
3324 using its __index__ method. If that method is non-existent or raises
3325 TypeError it goes on to try the __int__ method, as described below.
3326
Georg Brandlba83f822010-03-14 09:50:54 +00003327- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3328 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3329 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003330 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3331 inconsistent: __int__ was used for some integer codes but not for others, and
3332 the set of integer codes for which it was used differed between native packing
3333 and standard packing.)

3737Core and Builtins
3738-----------------
3739
Georg Brandlba83f822010-03-14 09:50:54 +00003740- The ``__complex__()`` method is now looked up on the class of instances to
3741 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003743- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3744 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3745
Mark Dickinson1b34d252010-01-01 17:27:30 +00003746- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003747 DeprecationWarning when passed a float argument where an integer was expected.
3748 These functions and methods now raise TypeError instead. The majority of the
3749 effects of this change are in the extension modules, but some core functions
3750 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3751 and many unicode/str methods.

3762 used to drop the time part of the result.
3763
Georg Brandlba83f822010-03-14 09:50:54 +00003764- Issue #1811: Improve accuracy and cross-platform consistency for true division
3765 of integers: the result of a/b is now correctly rounded for ints a and b (at
3766 least on IEEE 754 platforms), and in particular does not depend on the
3767 internal representation of a long.

3775
Georg Brandlba83f822010-03-14 09:50:54 +00003776 These executables now work properly with the arch(1) command: ``arch -ppc
3777 python`` will start a universal binary version of python in PPC mode (unlike
3778 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00003934- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3935 decimal string that's guaranteed to round back to x under correct rounding
3936 (with round-half-to-even rounding mode). Previously it gave a string based on
3937 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3938 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3939 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003940
Georg Brandlba83f822010-03-14 09:50:54 +00003941- Issue #7117: On almost all platforms: float-to-string and string-to-float
3942 conversions within Python are now correctly rounded. Places these conversions
3943 occur include: str for floats and complex numbers; the float and complex
3944 constructors; old-style and new-style numeric formatting; serialization and
3945 deserialization of floats and complex numbers using marshal, pickle and json;
3946 parsing of float and imaginary literals in Python code; Decimal-to-float
3947 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003948
Georg Brandlba83f822010-03-14 09:50:54 +00003949 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3950 providing correctly-rounded strtod and dtoa C functions. This code is
3951 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3952 the C compiler. There may be a small number of platforms on which correct
3953 operation of this code cannot be guaranteed, so the code is not used: notably,
3954 this applies to platforms where the C double format is not IEEE 754 binary64,
3955 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3956 and Python's configure script is unable to determine how to change the FPU
3957 precision. On these platforms conversions use the platform strtod and dtoa,
3958 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003960- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3961 uses the correctly-rounded string <-> float conversions described above (when
3962 available), and so produces correctly rounded results that will display nicely
3963 under the float repr. There are two related small changes: (1) round now
3964 accepts any class with an ``__index__()`` method for its second argument (but
3965 no longer accepts floats for the second argument), and (2) an excessively
3966 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3967 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004109
Georg Brandlba83f822010-03-14 09:50:54 +00004110 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4111 (2) parsing of strings representing infinities and nans was locale aware; and
4112 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00004113
Georg Brandlba83f822010-03-14 09:50:54 +00004114- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4115 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4116 but with at least one decimal point and with a default precision
4117 of 12. Previously, the behavior the same but with a default precision of 6.
4118 This more closely matches ``str()``, and reduces surprises when adding
4119 alignment flags to the empty presentation type. This also affects the new
4120 complex.__format__ in the same way.
4121
4122- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4123 classtype's, even if it was None. property now inserts the __doc__ into the
4124 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00004184- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00004185 untrackable objects are not tracked by the garbage collector. This can reduce
4186 the size of collections and therefore the garbage collection overhead on

4194 internal representation of integers, for performance reasons. Base 2**30 is
4195 enabled by default on 64-bit machines. Add --enable-big-digits option to
4196 configure, which overrides the default. Add sys.long_info structseq to
4197 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004298- Issue #4597: Fixed exception handling when the __exit__ function of a context
4299 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00004300
Georg Brandlba83f822010-03-14 09:50:54 +00004301- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00004302
Georg Brandlba83f822010-03-14 09:50:54 +00004303- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4304 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4305 instances. On a typical machine this saves 3 bytes of memory (on average) per
4306 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004307
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004308- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4309 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4310 instead of throwing a MemoryError.
4311
Georg Brandlba83f822010-03-14 09:50:54 +00004312- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4313 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004314
Benjamin Petersonc078f922008-11-21 22:27:24 +00004315- Issue #4367: Python would segfault during compiling when the unicodedata
4316 module couldn't be imported and \N escapes were present.
4317
Georg Brandlba83f822010-03-14 09:50:54 +00004318- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4319 file objects with closefd=False. The file descriptor is still kept open but
4320 the file object behaves like a closed file. The ``FileIO`` object also got a
4321 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004322
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004323- Issue #4348: Some bytearray methods returned that didn't cause any change to
4324 the bytearray, returned the same bytearray instead of a copy.
4325
Georg Brandlba83f822010-03-14 09:50:54 +00004326- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00004327
Benjamin Peterson273c2332008-11-17 22:39:09 +00004328- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
4329
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004330- Issue #4048: The parser module now correctly validates relative imports.
4331
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004332- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
4333 exec statement.
4334
Georg Brandlba83f822010-03-14 09:50:54 +00004335- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4336 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00004337
Benjamin Petersonbdca9422008-10-26 20:21:13 +00004338- Issue #4209: Enabling unicode_literals and the print_function in the same
4339 __future__ import didn't work.
4340
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004341- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004342 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004343
Georg Brandlba83f822010-03-14 09:50:54 +00004344- On windows, ``os.chdir()`` given unicode was not working if
4345 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4346 this code path is really executed because I cannot move to such directory on
4347 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004348
Georg Brandlba83f822010-03-14 09:50:54 +00004349- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4350 element is temporarily replaced with an equivalent frozenset. But the
4351 eventual KeyError would always report the empty ``frozenset()`` as the missing
4352 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004353
Georg Brandlba83f822010-03-14 09:50:54 +00004354- Issue #4509: Various issues surrounding resize of bytearray objects to which
4355 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00004356
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00004357- Issue #4748: Lambda generators no longer return a value.
4358
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00004359- Issue #3582: Use native TLS functions on Windows
4360
Gregory P. Smithae91d092009-03-02 05:13:57 +00004361- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
4362
Georg Brandlba83f822010-03-14 09:50:54 +00004363- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
4364 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00004365
Matthias Klose91a3b9e2009-04-05 21:19:13 +00004366- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
4367 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00004368
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004369- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4370 returned them on 64bit platforms.
4371
Walter Dörwalded960ac2009-05-03 22:36:33 +00004372- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4373 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4374 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4375 of using the replace error handler in PyUnicode_DecodeUTF8().
4376
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004377- Issue #3739: The unicode-internal encoder now reports the number of characters
4378 consumed like any other encoder (instead of the number of bytes).
4379
Georg Brandlba83f822010-03-14 09:50:54 +00004380- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4381 allocator will be automatically disabled when running under Valgrind. This
4382 gives improved memory leak detection when running under Valgrind, while taking
4383 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00004408- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
4409 ownership when the group is not forced, because the group may be different
4410 from the user's group and inherit from its container when the test is run.

Georg Brandlba83f822010-03-14 09:50:54 +00004452- Issue #6816: runpy now provides a run_path function that allows Python code to
4453 execute file paths that refer to source or compiled Python files as well as
4454 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00004455 __main__.py file. This allows applications that run other Python scripts to
4456 support the same flexibility as the CPython command line itself.
4457
Georg Brandlba83f822010-03-14 09:50:54 +00004458- Issue #7318: multiprocessing now uses a timeout when it fails to establish a

4460 timeout is 20 seconds, which should be amply sufficient for local connections.

5749
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005750- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5751 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5752 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5753 ``printf`` function, whereas PyString_FromFormat has an independent
5754 implementation and uses "%zd" on all platforms for size_t values.
5755 This makes a difference on win64, where ``printf`` needs "%Id" to display
5756 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005758- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5762 object; previously an int would be returned for small values. the __long__
5763 method is allowed to return either an int or a long, but the behaviour of
5764 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005766- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00005772 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005773 was correctly parsed but parsing of subsequent arguments failed.
5774
Vinay Sajip35e3b032008-09-01 14:33:59 +00005775- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005776 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5777 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5778 when given a tuple of classes as second argument, were looking up
5779 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5780 type object.
5781
Neal Norwitz18aa3882008-08-24 05:04:52 +00005782- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005851 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5852 for catch_warnings() also led to an improvement in the raising of a

5925-----------------
5926
Guido van Rossumf8402962008-08-20 15:01:50 +00005927- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5928 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5929 extensions do not automatically benefit from the class attribute
5930 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5931 to their tp_flags field if they care. This is a backwards
5932 compatibility feature; in 3.0, all types will use the cache by
5933 default.
5934
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005935- Keyword arguments can now follow starred arguments. (``f(a, *args,
5936 keyword=23)`` is now valid syntax.)
5937
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005938- ctypes function pointers that are COM methods have a boolean True
5939 value again.

5949 ValueError consistently across platforms.
5950
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005951- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5952 (64bit Unix, for example), unichr() would truncate its argument and return
5953 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5954
Neal Norwitze7d8be82008-07-31 17:17:14 +00005955- Apply security patches from Apple.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005957- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5958 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5959
Antoine Pitrou92f82162008-07-25 22:22:08 +00005960- Issue #1819: function calls with several named parameters are now on
5961 average 35% faster (as measured by pybench).
5962
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005963- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5964 the python debugger steps into a class statement: the free variables (local
5965 variables defined in an outer scope) would be deleted from the outer scope.
5966
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005967- Issue #2620: Overflow checking when allocating or reallocating memory
5968 was not always being done properly in some python types and extension
5969 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5970 all been updated to perform better checks and places in the code that
5971 would previously leak memory on the error path when such an allocation
5972 failed have been fixed.

5978
Benjamin Petersone977ad42008-08-20 01:42:01 +00005979- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5980 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5981
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005982- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5983 version reported by these tools does not necessarily follow the python
5984 version numbering scheme, so the module is less strict when parsing it.
5985
Nick Coghlanf70385a2008-08-18 12:42:46 +00005986- Issue #2235: Added Py3k warnings for types which will become unhashable
5987 under the stricter __hash__ inheritance rules in 3.0. Several types
5988 which did not meet the rules for hash invariants and were already
5989 unhashable in 3.0 have now been explicitly flagged as unhashable in
5990 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5991 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5992
Brett Cannon88f801d2008-08-18 00:46:22 +00005993- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5994 imported into the module but exposed as part of the module's API.
5995

6016
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006017- Issue #2676: in the email package, content-type parsing was hanging on
6018 pathological input because of quadratic or exponential behaviour of a
6019 regular expression.
6020
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006021- Issue #3476: binary buffered reading through the new "io" library is now
6022 thread-safe.
6023
Brett Cannonbf3157b2008-08-14 05:00:03 +00006024- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6025 since mimetools itself is deprecated. Because modules are cached, all
6026 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6027

6031 menu entries were not deleted.
6032
Brett Cannon83e81842008-08-09 23:30:55 +00006033- Copied the implementation of reduce() to _functools.reduce() to have a

6035
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006036- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6037 a MemoryError rather than silently stop the iteration.
6038
Guido van Rossum59ce9012008-08-09 14:55:34 +00006039- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6040 to _sre.compile() will now be rejected. This should not affect anybody
6041 since the re.compile() function never generates invalid re-bytecode.
6042
Skip Montanaroa032bf42008-08-08 22:52:51 +00006043- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6044 upon first access it can be automatically initialized from the csv file if
6045 it wasn't initialized during instantiation.
6046
Brett Cannon3aa2a492008-08-06 22:28:09 +00006047- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6048 the reload() built-in has been removed.
6049
Brett Cannon7e30b672008-08-04 21:52:25 +00006050- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006051 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006062 asking for a specific length. This problem only affected files opened
6063 using the new "io" module, not the built-in open() function.

6089 file name rather than a ZipInfo instance, so files are extracted with
6090 mode 0600 rather than 000 under Unix.
6091
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006092- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6093 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006104- Issue #2235: the C API function PyObject_HashNotImplemented and its
6105 interaction with the tp_hash slot (added in 2.6b2) are now documented
6106
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006107- Issue #643841: The language reference now provides more detailed
6108 coverage of the lookup process for special methods. The disclaimers
6109 regarding lack of coverage of new-style classes have also been
6110 removed, since the coverage is now fairly reasonable.

6114================================
6115
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006116*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006118Core and Builtins
6119-----------------
6120
Georg Brandl3e483f62008-07-16 22:57:41 +00006121- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6122 its methods now allow for items objects that can be converted to
6123 an integer using operator.index().
6124
Mark Dickinson64b7e502008-07-16 09:40:03 +00006125- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6126 produced a ValueError instead of giving the correct float.
6127
Eric Smitha5fa5a22008-07-16 00:11:49 +00006128- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6129 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6130
Mark Dickinson7103aa42008-07-15 19:08:33 +00006131- Issue #3008: the float type has a new instance method 'float.hex'
6132 and a new class method 'float.fromhex' to convert floating-point
6133 numbers to and from hexadecimal strings, respectively.
6134
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006135- Issue #2235: __hash__ is once again inherited by default. To allow
6136 collections.Hashable to remain meaningful in the presence of the
6137 default hash implementation (object.__hash__), it is now possible
6138 to explicit block inheritance of hash by setting __hash__=None at
6139 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6140 level.
6141
Nick Coghlanb028f502008-07-13 14:52:36 +00006142- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6143 the parent module cannot be found while performing an absolute import.
6144 This means that an incorrectly defined __package__ attribute will
6145 now only prevent relative imports in that module rather than causing
6146 all imports from that module to fail.
6147
Nick Coghlan14ff9942008-07-08 14:21:42 +00006148- Issue #2517: Allow unicode messages in Exceptions again by correctly
6149 bypassing the instance dictionary when looking up __unicode__ on
6150 new-style classes.
6151
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006152- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6153 set to a custom object whose write() method happens to install
6154 another file in sys.stdout.
6155
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006156- Issue #3088: Corrected a race condition in classes derived from
6157 threading.local: the first member set by a thread could be saved in
6158 another thread's dictionary.
6159
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006160- Issue #3004: Minor change to slice.indices(): the start and stop
6161 arguments are now treated identically, making the behaviour easier
6162 to describe and understand. For example, slice(None, -10,
6163 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6164 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6165 10, -1).
6166
Georg Brandl278fc502008-07-19 12:46:12 +00006167- Issue #3219: Calling a function with repeated keyword arguments,
6168 f(a=2, a=23), would not cause a syntax error. This was a regression
6169 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006170
Georg Brandl278fc502008-07-19 12:46:12 +00006171- Issue #2862: Make int and float freelist management consistent with
6172 other freelists. Changes their CompactFreeList apis into
6173 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00006178- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6179 api functions without holding the GIL, which could lead to a fatal
6180 error when they failed.
6181
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006182- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00006190- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6191 ForkingPickler.register() to resolve conflict with ctypes.
6192
Vinay Sajip51e65192008-07-18 09:01:10 +00006193- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00006195- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6196 a valid dlerror() message.
6197
Thomas Heller2bad6572008-07-15 17:19:50 +00006198- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6199 incomplete structure was created.
6200

6204
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006205- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006206
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006207- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6208 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006209 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006210 content-length. The problem had been corrected in the 2.4 branch, but never
6211 merged into trunk.
6212
Georg Brandle78fbcc2008-07-05 10:13:36 +00006213- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006224 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006225
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006226- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6227 handling is now the same as that of other special attributes like __name__).
6228
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006229- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6230 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00006619 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006620
6621 This is controlled by the configure argument ``--with-universal-archs``:
6622
6623 - ``--with-universal-archs=all``: install 4-way universal
6624
6625 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6626
6627 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6628
6629 This option should be used in combination with ``--enable-universalsdk=``.
6630
6631 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 +00006681- Issue #1631171: Re-implement the 'warnings' module in C (the
6682 original Python code has been kept as backup). This will allow for
6683 using the 'warning's machinery in such places as the parser where
6684 use of pure Python code is not possible. Both the ``showarning()``
6685 and ``formatwarning()`` gain an optional 'line' argument which is
6686 not called by default for backwards-compatibility reasons. Setting
6687 ``warnings.showwarning()`` to an implementation that lacks support
6688 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006751- Issue #2550: The approach used by client/server code for obtaining
6752 ports to listen on in network-oriented tests has been refined in an
6753 effort to facilitate running multiple instances of the entire
6754 regression test suite in parallel without issue.
6755 test_support.bind_port() has been fixed such that it will always
6756 return a unique port -- which wasn't always the case with the
6757 previous implementation, especially if socket options had been set
6758 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6759 new implementation of bind_port() will actually raise an exception
6760 if it is passed an AF_INET/SOCK_STREAM socket with either the
6761 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6762 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6763 the socket it's been passed. This currently only applies to
6764 Windows. This option prevents any other sockets from binding to the
6765 host/port we've bound to, thus removing the possibility of the
6766 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6767 when a second SOCK_STREAM socket binds and accepts to a host/port
6768 that's already been bound by another socket. The optional preferred
6769 port parameter to bind_port() has been removed. Under no
6770 circumstances should tests be hard coding ports!
6771
6772 test_support.find_unused_port() has also been introduced, which will
6773 pass a temporary socket object to bind_port() in order to obtain an
6774 unused port. The temporary socket object is then closed and
6775 deleted, and the port is returned. This method should only be used
6776 for obtaining an unused port in order to pass to an external program
6777 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6778 a parameter to a server-oriented class that doesn't give you direct
6779 access to the underlying socket used.
6780
6781 Finally, test_support.HOST has been introduced, which should be used
6782 for the host argument of any relevant socket calls (i.e. bind and
6783 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006784
6785 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006786 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

6788 test_asynchat and test_socket_ssl.
6789
Georg Brandl3ee81df2008-05-17 18:14:43 +00006790 It is now possible for multiple instances of the regression test
6791 suite to run in parallel without issue.

7058-----------------
7059
Fred Drakea8ee94b2008-03-01 02:45:07 +00007060- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007061 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007062
Georg Brandlad61bc82008-02-23 15:11:18 +00007063- Issue #2067: file.__exit__() now calls subclasses' close() method.
7064
7065- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007066
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007067- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007068 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007069
Eric Smitha73fbe72008-02-23 03:09:44 +00007070- Added the future_builtins module, which contains hex() and oct().
7071 These are the PEP 3127 version of these functions, designed to be
7072 compatible with the hex() and oct() builtins from Python 3.0. They
7073 differ slightly in their output formats from the existing, unchanged
7074 Python 2.6 builtins. The expected usage of the future_builtins
7075 module is:
7076 from future_builtins import hex, oct
7077
Eric Smith7ef40bf2008-02-20 23:34:22 +00007078- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7079 exponents for exponents with absolute value < 100. Follows C99
7080 standard. This is a change on Windows, which would use 3 digits.
7081 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7082 so that any alterations it does to the resulting string will be
7083 available in stringlib/formatter.h (for float.__format__).
7084
Eric Smith5a3c1352008-02-19 13:21:56 +00007085- Implemented PEP 3101, Advanced String Formatting. This adds a new
7086 builtin format(); a format() method for str and unicode; a
7087 __format__() method to object, str, unicode, int, long, float, and
7088 datetime; the class string.Formatter; and the C API
7089 PyObject_Format().
7090
Georg Brandl3ee81df2008-05-17 18:14:43 +00007091- Fixed several potential crashes, all caused by specially crafted
7092 __del__ methods exploiting objects in temporarily inconsistent
7093 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007094
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007095- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007096 prevent a possible crash: an Abstract Base Class would try to access
7097 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007098
Georg Brandl3ee81df2008-05-17 18:14:43 +00007099- Fixed repr() and str() of complex numbers with infinity or nan as
7100 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007101
Georg Brandl3ee81df2008-05-17 18:14:43 +00007102- Clear all free lists during a gc.collect() of the highest generation
7103 in order to allow pymalloc to free more arenas. Python may give back
7104 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007105
Georg Brandl3ee81df2008-05-17 18:14:43 +00007106- Issue #2045: Fix an infinite recursion triggered when printing a
7107 subclass of collections.defaultdict, if its default_factory is set
7108 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007109
Christian Heimesf75dbef2008-02-08 00:11:31 +00007110- Fixed a minor memory leak in dictobject.c. The content of the free
7111 list was not freed on interpreter shutdown.
7112
Georg Brandl21e99f42010-03-07 15:23:59 +00007113- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007114 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007115
Georg Brandl3ee81df2008-05-17 18:14:43 +00007116- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7117 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007118 to compact the internal free lists of pre-allocted ints and floats.
7119
Georg Brandl3ee81df2008-05-17 18:14:43 +00007120- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7121 calls. Python expected the return type int but the fork familie
7122 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007123
Georg Brandl3ee81df2008-05-17 18:14:43 +00007124- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7125 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007126
Georg Brandl3ee81df2008-05-17 18:14:43 +00007127- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7128 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007129
Georg Brandl3ee81df2008-05-17 18:14:43 +00007130- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7131 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007132
Georg Brandl3ee81df2008-05-17 18:14:43 +00007133- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7134 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007135
Georg Brandl3ee81df2008-05-17 18:14:43 +00007136- Patch #1473257: generator objects gain a gi_code attribute. This is
7137 the same object as the func_code attribute of the function that
7138 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007139
Georg Brandl3ee81df2008-05-17 18:14:43 +00007140- Issue #1920: "while 0" statements were completely removed by the
7141 compiler, even in the presence of an "else" clause, which is
7142 supposed to be run when the condition is false. Now the compiler
7143 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007144
Guido van Rossumeead05f2008-01-24 18:21:02 +00007145- A few crashers fixed: weakref_in_del.py (issue #1377858);
7146 loosing_dict_ref.py (issue #1303614, test67.py);
7147 borrowed_ref_[34].py (not in tracker).
7148
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007149- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007150 suppressed while an extension is loaded by calling SetErrorMode in
7151 dynload_win.c. The error is still reported properly.
7152
Georg Brandl3ee81df2008-05-17 18:14:43 +00007153- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007154 several extension methods and modules do not work without unicode
7155 support.
7156
Georg Brandl26543b12008-01-21 18:36:51 +00007157- Issue #1882: when compiling code from a string, encoding cookies in the
7158 second line of code were not always recognized correctly.
7159
Georg Brandl14404b62008-01-19 19:27:05 +00007160- Issue #1679: "0x" was taken as a valid integer literal.
7161
Georg Brandl6caad7d2008-01-26 14:19:22 +00007162- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007163 added.
7164
Christian Heimesc94e2b52008-01-14 04:13:37 +00007165- sys.float_info / PyFloat_GetInfo: The floating point information
7166 object was converted from a dict to a specialized structseq object.
7167
Georg Brandl3ee81df2008-05-17 18:14:43 +00007168- Patch #1816: Added sys.flags structseq. It exposes the status of
7169 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007170
Georg Brandl3ee81df2008-05-17 18:14:43 +00007171- Objects/structseq.c: Implemented new structseq representation. The
7172 patch makes structseqs (e.g. the return value of os.stat) more
7173 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007174
Georg Brandl3ee81df2008-05-17 18:14:43 +00007175- Patch #1700288: added a type attribute cache that caches method
7176 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007177
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007178- Bug #1776: __import__() no longer accepts filenames on any platform.
7179 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007180
Georg Brandlaed6c662008-01-07 17:25:53 +00007181- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7182
Georg Brandl3ee81df2008-05-17 18:14:43 +00007183- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7184 envvar and sys.dont_write_bytecode attribute. All these can be set
7185 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007186
Georg Brandl3ee81df2008-05-17 18:14:43 +00007187- Improve some exception messages when Windows fails to load an
7188 extension module. Now we get for example '%1 is not a valid Win32
7189 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007190
Georg Brandl3ee81df2008-05-17 18:14:43 +00007191- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007193- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7194 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007195
Christian Heimes0a8143f2007-12-18 23:22:54 +00007196- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197 and INF. float("nan"), float("inf") and float("-inf") now work on
7198 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007199
Georg Brandl3ee81df2008-05-17 18:14:43 +00007200- Compiler now generates simpler and faster code for dictionary
7201 literals. The oparg for BUILD_MAP now indicates an estimated
7202 dictionary size. There is a new opcode, STORE_MAP, for adding
7203 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007204
Georg Brandl3ee81df2008-05-17 18:14:43 +00007205- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Issue #1538: Avoid copying string in split/rsplit if the split char
7211 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007212
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007213- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007214 SystemError.
7215
Nick Coghlanef01d822007-12-03 12:55:17 +00007216- PEP 366: Allow explicit relative imports when executing modules
7217 inside packages with the -m switch via a new module level
7218 __package__ attribute.
7219
Georg Brandl3ee81df2008-05-17 18:14:43 +00007220- Issue #1402: Fix a crash on exit, when another thread is still
7221 running, and if the deallocation of its frames somehow calls the
7222 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007223

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007227 attribute of an empty cell object.
7228
Georg Brandl3ee81df2008-05-17 18:14:43 +00007229- Issue #1460: The utf-7 incremental decoder did not accept truncated
7230 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007231
Georg Brandl3ee81df2008-05-17 18:14:43 +00007232- Patch #1739468: Directories and zipfiles containing a __main__.py
7233 file can now be directly executed by passing their name to the
7234 interpreter. The directory/zipfile is automatically inserted as the
7235 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007236
Georg Brandl3ee81df2008-05-17 18:14:43 +00007237- Issue #1265: Fix a problem with sys.settrace, if the tracing
7238 function uses a generator expression when at the same time the
7239 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007240
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007241- sets and frozensets now have an isdisjoint() method.
7242
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007243- optimize the performance of builtin.sum().
7244
Neal Norwitz44f326e2007-10-05 05:29:17 +00007245- Fix warnings found by the new version of the Coverity checker.
7246
Georg Brandl21e99f42010-03-07 15:23:59 +00007247- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007248 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7249 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007250
Georg Brandl3ee81df2008-05-17 18:14:43 +00007251- Issue #1686386: Tuple's tp_repr did not take into account the
7252 possibility of having a self-referential tuple, which is possible
7253 from C code. Nor did object's tp_str consider that a type's tp_str
7254 could do something that could lead to an inifinite recursion.
7255 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7256 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007257
Georg Brandl3ee81df2008-05-17 18:14:43 +00007258- Issue #1164: It was possible to trigger deadlock when using the
7259 'print' statement to write to a file since the GIL was not released
7260 as needed. Now PyObject_Print() does the right thing along with
7261 various tp_print implementations of the built-in types and those in
7262 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007263
Georg Brandl3ee81df2008-05-17 18:14:43 +00007264- Issue #1147: Exceptions were directly allowing string exceptions in
7265 their throw() method even though string exceptions no longer
7266 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007267

Brett Cannon1e534b52007-09-07 04:18:30 +00007271- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007272 PyObject_Call() never calling back out to Python code to trigger
7273 recursion depth updates/checks. Required the creation of a static
7274 RuntimeError instance in case normalizing an exception put the
7275 recursion check value past its limit. Fixes crashers
7276 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007277
Georg Brandl3ee81df2008-05-17 18:14:43 +00007278- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007291- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007292 __*__ attributes. (Some already existed, e.g., __doc__ and
7293 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007294
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007295- Add -3 option to the interpreter to warn about features that are

7299 calls.
7300
Collin Winter62903052007-05-18 23:11:24 +00007301- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007302 "except E as target:". This is to provide forwards compatibility
7303 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007304
Brett Cannon229cee22007-05-05 01:34:02 +00007305- Deprecate BaseException.message as per PEP 352.
7306
Georg Brandl3ee81df2008-05-17 18:14:43 +00007307- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007308 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007309
Vinay Sajip8549ce32007-05-06 17:53:37 +00007310- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007311 setting a plain string, ie don't expand to single letter identifiers.
7312
Raymond Hettinger13936692007-04-11 18:40:58 +00007313- Request #1191699: Slices can now be pickled.

7317 remaining characters.
7318
Georg Brandl5cb76c12007-03-21 09:00:39 +00007319- Patch #1682205: a TypeError while unpacking an iterable is no longer

7323
Guido van Rossum143b5642007-03-23 04:58:42 +00007324- Bug #1683368: The object.__init__() and object.__new__() methods are
7325 now stricter in rejecting excess arguments. The only time when
7326 either allows excess arguments is when it is not overridden and the
7327 other one is. For backwards compatibility, when both are
7328 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007329 warning later). Also, type.__init__() insists on the same signature
7330 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007331
Georg Brandl3ee81df2008-05-17 18:14:43 +00007332- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7333 object to complex using its __complex__() method before falling back
7334 to the __float__() method. Therefore, the functions in the cmath
7335 module now can operate on objects that define a __complex__()
7336 method.

7340 same slot names.

7353
Georg Brandl7b9c5552007-03-12 14:30:05 +00007354- Bug #1678647: write a newline after printing an exception in any
7355 case, even when converting the value to a string failed.
7356
Georg Brandl871f1bc2007-03-12 13:17:36 +00007357- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007358 its argument, if it exists. If not, it will work like before. This
7359 allows customizing the output of dir() in the presence of a
7360 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007361
Collin Winter276887b2007-03-12 16:11:39 +00007362- Patch #922167: Python no longer segfaults when faced with infinitely
7363 self-recursive reload() calls (as reported by bug #742342).
7364

7369 parthensized forms. This means complex(repr(x)) now works instead of
7370 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007371
Georg Brandlaa2321b2007-03-07 00:40:28 +00007372- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007373 makes the filenames the warning module prints much more sensible
7374 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007375

7377 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007378 variable is given, but break into the interactive interpreter just

Georg Brandl0fca97a2007-03-05 22:28:08 +00007387- Patch #1674228: when assigning a slice (old-style), check for the
7388 sq_ass_slice instead of the sq_slice slot.
7389
Georg Brandl3ee81df2008-05-17 18:14:43 +00007390- When printing an unraisable error, don't print exceptions. before
7391 the name. This duplicates the behavior whening normally printing
7392 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007925 AttributeError instead of an IOError when the server's response
7926 didn't contain a valid HTTP status line.

8017 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00008302- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8303 with RFC 3207 and forgets any knowledge obtained from the server not
8304 obtained from the TLS negotiation itself. Patch contributed by Bill
8305 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008306
Georg Brandl3ee81df2008-05-17 18:14:43 +00008307- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008308 that the SMTP.starttls() caller no longer needs to call ehlo()
8309 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008310 does not claim to support starttls. Adds the
8311 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8392 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8393 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00008410 time so that opening a database previously created with the DB_DUP
8411 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8412 opens. Specifically: dictionary assignment to a DB object will
8413 replace all values for a given key when the database allows
8414 duplicate values. DB users should use DB.put(k, v) when they want
8415 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008416

8422 characters with ASCII value less than 32. Also, it correctly quotes
8423 dots only if they occur on a single line, as opposed to the previous
8424 behavior of quoting dots if they are the second character of any
8425 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008755- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8756 to ``PyTuple_SetItem``, it can be used to populate a brand new
8757 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008758
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008759- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008761- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8762 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8763 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008764
8765- Patch #1720595: add T_BOOL to the range of structmember types.
8766
8767- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8768 ``PyFloat_GetInfo()`` to the float API.
8769
Georg Brandl3ee81df2008-05-17 18:14:43 +00008770- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8771 of w# format code incorrectly truncated the length to an int, even
8772 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8773 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008774
Georg Brandl3ee81df2008-05-17 18:14:43 +00008775- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8776 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008778- PEP 3123: Provide forward compatibility with Python 3.0, while
8779 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8780 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008781
Georg Brandl3ee81df2008-05-17 18:14:43 +00008782- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8783 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008784
8785- Patch #1733960: Allow T_LONGLONG to accept ints.
8786
8787- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8788
Christian Heimes000a0742008-01-03 22:16:32 +00008789- Added a new API function ``PyImport_ImportModuleNoBlock``.
8790
Georg Brandl6caad7d2008-01-26 14:19:22 +00008791- Bug #1637022: Prefix AST symbols with _Py_.
8792
8793- Fix some leftovers from the conversion from int to Py_ssize_t
8794 (relevant to strings and sequences of more than 2**31 items).
8795
8796- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8797 outside of pystate.c and should not be necessary.
8798
Georg Brandl3ee81df2008-05-17 18:14:43 +00008799- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8800 absolute imports. In earlier versions they might have used relative
8801 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008802
Georg Brandl3ee81df2008-05-17 18:14:43 +00008803- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8804 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008805
Georg Brandl3ee81df2008-05-17 18:14:43 +00008806- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8807 macro so it can be used as an expression.

8812
Georg Brandl3ee81df2008-05-17 18:14:43 +00008813- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8814 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8815 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8816 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008817
Georg Brandl3ee81df2008-05-17 18:14:43 +00008818- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00008829- buildtools now raises a DeprecationWarning.
8830
Georg Brandl3ee81df2008-05-17 18:14:43 +00008831- Removed the macfs module. It had been deprecated since Python 2.5.
8832 This lead to the deprecation of macostools.touched() as it relied
8833 solely on macfs and was a no-op under OS X.
