Ned Deily18fae3f2013-01-31 01:24:55 -0800693- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
694 In particular, fix extension module build failures when trying to use
695 32-bit-only installer Pythons on systems with Xcode 4 (currently
696 OS X 10.8, 10.7, and optionally 10.6).
697 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
698 * Since Xcode 4 removes ppc support, extension module builds now
699 check for ppc compiler support and by default remove ppc and
700 ppc64 archs when they are not available.
701 * Extension module builds now revert to using system installed
702 headers and libs (/usr and /System/Library) if the SDK used
703 to build the interpreter is not installed or has moved.
704 * Try to avoid building extension modules with deprecated
705 and problematic Apple llvm-gcc compiler. If original compiler
706 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +0100931- Issue #12973: Fix overflow checks that invoked undefined behaviour in

933 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100934 compiler optimizing the check away. Also fix similar overflow checks
935 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
936 bugs caused test failures with recent versions of Clang.

Ned Deily0d0ea482012-02-10 12:59:06 +01001011- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1012 Distutils-based packages with C extension modules may fail because
1013 Apple has removed gcc-4.2, the version used to build python.org
1014 64-bit/32-bit Pythons. If the user does not explicitly override
1015 the default C compiler by setting the CC environment variable,
1016 Distutils will now attempt to compile extension modules with clang
1017 if gcc-4.2 is required but not found. Also as a convenience, if
1018 the user does explicitly set CC, substitute its value as the default
1019 compiler in the Distutils LDSHARED configuration variable for OS X.
1020 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1021 SDK, neither of which are available in Xcode 4. This change does not
1022 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001295- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1296 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1297 interpreter process. This could cause failures in non-Distutils subprocesses
1298 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001299 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001300 deployment target only in the environment of each build subprocess. It is
1301 still possible to globally override the default by setting
1302 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1303 greater or equal to the default value, the value with which the interpreter
1304 was built.

1333 updating the check interval, so if the user decreases the check interval,
1334 the ticker doesn't have to wind down to zero from the old starting point
1335 before the new interval takes effect. And if the user increases the
1336 interval, it makes sure the new limit takes effect right away rather have an
1337 early task switch before recognizing the new interval.

2289 This prevents user-created self-referencing ordered dictionaries from
2290 becoming permanently uncollectable GC garbage. The downside is that

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002752- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2753 start byte and the continuation byte(s) are now considered invalid, instead
2754 of the number of bytes specified by the start byte.
2755 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2756 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2757 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002766- Issue #8748: Fix two issues with comparisons between complex and integer
2767 objects. (1) The comparison could incorrectly return True in some cases
2768 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2769 (2) The comparison raised an OverflowError for large integers, leading
2770 to unpredictable exceptions when combining integers and complex objects
2771 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00002773- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00002910- Issue #1533: Fix inconsistency in range function argument processing: any
2911 non-float non-integer argument is now converted to an integer (if possible)
2912 using its __int__ method. Previously, only small arguments were treated this
2913 way; larger arguments (those whose __int__ was outside the range of a C long)

Georg Brandlfee0f442010-05-22 21:26:21 +00002922 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00002923 benefit compared to the dynamic memory allocation fallback. Patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00002964- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
2965 operation raises multiple signals and more than one of those signals is
2966 trapped, the specification determines the order in which the signals should be
2967 handled. In many cases this order wasn't being followed, leading to the wrong
2968 Python exception being raised.

3135Core and Builtins
3136-----------------
3137
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003138- Issue #7301: Add environment variable $PYTHONWARNINGS.
3139
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003140- Issue #8329: Don't return the same lists from select.select when no fds are
3141 changed.
3142
Georg Brandlfee0f442010-05-22 21:26:21 +00003143- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003144 on 64-bit machines. The shift count for either left or right shift is
3145 permitted to be up to sys.maxsize.
3146
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003147- Ensure that tokenization of identifiers is not affected by locale.
3148
Georg Brandlfee0f442010-05-22 21:26:21 +00003149- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003150
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003151- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3152
Georg Brandlfee0f442010-05-22 21:26:21 +00003153- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3154 with a non-empty format string. This is an effort to future-proof user
3155 code. If a derived class does not currently implement __format__ but later
3156 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003157 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003158 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003159
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003160- Issue #8268: Old-style classes (not just instances) now support weak
3161 references.

3164 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00003165
Victor Stinnerc7790ed2010-03-22 12:36:28 +00003166- Issue #1583863: An unicode subclass can now override the __unicode__ method

Benjamin Peterson96545892010-03-21 20:21:00 +00003168- Issue #6474: Make error message from passing an inadequate number of keyword
3169 arguments to a function correct.
3170
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00003171- Issue #8164: Don't allow lambda functions to have a docstring.
3172
Victor Stinner66644262010-03-10 22:30:19 +00003173- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003174 (SIGINT). If an error occurs while importing the site module, the error is
3175 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00003176 module.
3177
Collin Winter001a3952010-03-18 21:54:01 +00003178- Code objects now support weak references.

3184
Antoine Pitrouf9de5342010-04-05 21:35:07 +00003185- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00003186 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Benjamin Peterson76a23c12010-04-04 23:23:22 +00003189- Issue #8310: Allow dis to examine new style classes.
3190
Georg Brandlfee0f442010-05-22 21:26:21 +00003191- Issue #8257: The Decimal construct now accepts a float instance directly,
3192 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003193
3194 >>> Decimal(1.1)
3195 Decimal('1.100000000000000088817841970012523233890533447265625')
3196
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003197- collections.Counter() now supports a subtract() method.
3198
Georg Brandlfee0f442010-05-22 21:26:21 +00003199- The functools module now has a total_ordering() class decorator to simplify
3200 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00003201
Georg Brandlfee0f442010-05-22 21:26:21 +00003202- The functools module also adds cmp_to_key() as a tool to transition old-style
3203 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003204
Georg Brandlfee0f442010-05-22 21:26:21 +00003205- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3206 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003207
Georg Brandlfee0f442010-05-22 21:26:21 +00003208- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3209 InvalidOperation instead of returning False. (Comparisons involving a quiet
3210 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3211 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003212
Georg Brandlfee0f442010-05-22 21:26:21 +00003213- Issue #2531: Comparison operations between floats and Decimal instances now
3214 return a result based on the numeric values of the operands; previously they
3215 returned an arbitrary result based on the relative ordering of id(float) and
3216 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003217
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003218- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003219 argument `-` which tells it to read files to compile from stdin. Each line is
3220 read on demand and the named file is compiled immediately. (Original patch by
3221 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003222
Georg Brandlfee0f442010-05-22 21:26:21 +00003223- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
3224 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00003226- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3227 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003228 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003229
Georg Brandlfee0f442010-05-22 21:26:21 +00003230- Comparisons using one of <, <=, >, >= between a complex instance and a
3231 Fractions instance now raise TypeError instead of returning True/False. This
3232 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3233 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00003234

3243
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003244- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00003245 didn't support chflags() (for example ZFS under FreeBSD). The error is now
3246 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00003247
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00003248- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
3249 deprecated.
3250
Georg Brandlfee0f442010-05-22 21:26:21 +00003251- Issue #7860: platform.uname now reports the correct 'machine' type when Python
3252 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00003253

3258 existing at the same time, causing a Unicode error when configuration code
3259 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00003260
Georg Brandlfee0f442010-05-22 21:26:21 +00003261- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
3262 when logging occurs.

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003288- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003289 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3290 log file to compute the next rollover time. If the log file does not exist,

Georg Brandlba83f822010-03-14 09:50:54 +00003301- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3302 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3303 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003332- Issue #8300: When passing a non-integer argument to struct.pack with any
3333 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003337- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3338 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3339 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003340 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3341 inconsistent: __int__ was used for some integer codes but not for others, and
3342 the set of integer codes for which it was used differed between native packing
3343 and standard packing.)

3748-----------------
3749
Georg Brandlba83f822010-03-14 09:50:54 +00003750- The ``__complex__()`` method is now looked up on the class of instances to
3751 make it consistent with other special methods.

3755
Mark Dickinson1b34d252010-01-01 17:27:30 +00003756- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003757 DeprecationWarning when passed a float argument where an integer was expected.
3758 These functions and methods now raise TypeError instead. The majority of the
3759 effects of this change are in the extension modules, but some core functions
3760 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3761 and many unicode/str methods.

3775 of integers: the result of a/b is now correctly rounded for ints a and b (at
3776 least on IEEE 754 platforms), and in particular does not depend on the
3777 internal representation of a long.

3785
Georg Brandlba83f822010-03-14 09:50:54 +00003786 These executables now work properly with the arch(1) command: ``arch -ppc
3787 python`` will start a universal binary version of python in PPC mode (unlike

3928 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003929
Georg Brandlba83f822010-03-14 09:50:54 +00003930- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3931 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003932
Georg Brandlba83f822010-03-14 09:50:54 +00003933- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3934 1e-100 used to raise OverflowError, but now gives the requested 120
3935 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003944- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3945 decimal string that's guaranteed to round back to x under correct rounding
3946 (with round-half-to-even rounding mode). Previously it gave a string based on
3947 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3948 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3949 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003950
Georg Brandlba83f822010-03-14 09:50:54 +00003951- Issue #7117: On almost all platforms: float-to-string and string-to-float
3952 conversions within Python are now correctly rounded. Places these conversions
3953 occur include: str for floats and complex numbers; the float and complex
3954 constructors; old-style and new-style numeric formatting; serialization and
3955 deserialization of floats and complex numbers using marshal, pickle and json;
3956 parsing of float and imaginary literals in Python code; Decimal-to-float
3957 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003958
Georg Brandlba83f822010-03-14 09:50:54 +00003959 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3960 providing correctly-rounded strtod and dtoa C functions. This code is
3961 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3962 the C compiler. There may be a small number of platforms on which correct
3963 operation of this code cannot be guaranteed, so the code is not used: notably,
3964 this applies to platforms where the C double format is not IEEE 754 binary64,
3965 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3966 and Python's configure script is unable to determine how to change the FPU
3967 precision. On these platforms conversions use the platform strtod and dtoa,
3968 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003970- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3971 uses the correctly-rounded string <-> float conversions described above (when
3972 available), and so produces correctly rounded results that will display nicely
3973 under the float repr. There are two related small changes: (1) round now
3974 accepts any class with an ``__index__()`` method for its second argument (but
3975 no longer accepts floats for the second argument), and (2) an excessively
3976 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3977 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004119
Georg Brandlba83f822010-03-14 09:50:54 +00004120 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4121 (2) parsing of strings representing infinities and nans was locale aware; and
4122 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004124- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4125 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4126 but with at least one decimal point and with a default precision
4127 of 12. Previously, the behavior the same but with a default precision of 6.
4128 This more closely matches ``str()``, and reduces surprises when adding
4129 alignment flags to the empty presentation type. This also affects the new
4130 complex.__format__ in the same way.
4131
4132- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4133 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandl6425a2f2008-12-28 11:54:53 +00004293- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004294 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00004295
Skip Montanarof205c132008-12-23 03:30:15 +00004296- Added test case to ensure attempts to read from a file opened for writing
4297 fail.
4298
Georg Brandlba83f822010-03-14 09:50:54 +00004299- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
4300 elapsed times, not only when some objects are uncollectable/unreachable.
4301 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00004302
Mark Dickinson1a707982008-12-17 16:14:37 +00004303- Issue #3439: Add a bit_length method to int and long.
4304
Georg Brandlba83f822010-03-14 09:50:54 +00004305- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
4306 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00004307
Georg Brandlba83f822010-03-14 09:50:54 +00004308- Issue #4597: Fixed exception handling when the __exit__ function of a context
4309 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00004310
Georg Brandlba83f822010-03-14 09:50:54 +00004311- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00004312
Georg Brandlba83f822010-03-14 09:50:54 +00004313- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4314 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4315 instances. On a typical machine this saves 3 bytes of memory (on average) per
4316 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00004317
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004318- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4319 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4320 instead of throwing a MemoryError.
4321
Georg Brandlba83f822010-03-14 09:50:54 +00004322- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4323 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00004324
Benjamin Petersonc078f922008-11-21 22:27:24 +00004325- Issue #4367: Python would segfault during compiling when the unicodedata
4326 module couldn't be imported and \N escapes were present.
4327
Georg Brandlba83f822010-03-14 09:50:54 +00004328- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4329 file objects with closefd=False. The file descriptor is still kept open but
4330 the file object behaves like a closed file. The ``FileIO`` object also got a
4331 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00004332
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004333- Issue #4348: Some bytearray methods returned that didn't cause any change to
4334 the bytearray, returned the same bytearray instead of a copy.
4335
Georg Brandlba83f822010-03-14 09:50:54 +00004336- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00004338- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
4339
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00004340- Issue #4048: The parser module now correctly validates relative imports.
4341
Benjamin Petersondcee09d2008-10-31 02:16:05 +00004342- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
4343 exec statement.
4344
Georg Brandlba83f822010-03-14 09:50:54 +00004345- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
4346 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00004347
Benjamin Petersonbdca9422008-10-26 20:21:13 +00004348- Issue #4209: Enabling unicode_literals and the print_function in the same
4349 __future__ import didn't work.
4350
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004351- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004352 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004353
Georg Brandlba83f822010-03-14 09:50:54 +00004354- On windows, ``os.chdir()`` given unicode was not working if
4355 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4356 this code path is really executed because I cannot move to such directory on
4357 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004358
Georg Brandlba83f822010-03-14 09:50:54 +00004359- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4360 element is temporarily replaced with an equivalent frozenset. But the
4361 eventual KeyError would always report the empty ``frozenset()`` as the missing
4362 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00004363
Georg Brandlba83f822010-03-14 09:50:54 +00004364- Issue #4509: Various issues surrounding resize of bytearray objects to which
4365 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00004366
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00004367- Issue #4748: Lambda generators no longer return a value.

4370
Gregory P. Smithae91d092009-03-02 05:13:57 +00004371- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
4372
Georg Brandlba83f822010-03-14 09:50:54 +00004373- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
4374 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00004375
Matthias Klose91a3b9e2009-04-05 21:19:13 +00004376- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
4377 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00004378
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004379- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4380 returned them on 64bit platforms.
4381
Walter Dörwalded960ac2009-05-03 22:36:33 +00004382- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4383 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4384 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4385 of using the replace error handler in PyUnicode_DecodeUTF8().
4386
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004387- Issue #3739: The unicode-internal encoder now reports the number of characters
4388 consumed like any other encoder (instead of the number of bytes).
4389
Georg Brandlba83f822010-03-14 09:50:54 +00004390- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4391 allocator will be automatically disabled when running under Valgrind. This
4392 gives improved memory leak detection when running under Valgrind, while taking
4393 advantage of pymalloc at other times.

4420 from the user's group and inherit from its container when the test is run.

5759
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005760- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5761 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5762 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5763 ``printf`` function, whereas PyString_FromFormat has an independent
5764 implementation and uses "%zd" on all platforms for size_t values.
5765 This makes a difference on win64, where ``printf`` needs "%Id" to display
5766 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005768- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5772 object; previously an int would be returned for small values. the __long__
5773 method is allowed to return either an int or a long, but the behaviour of
5774 float objects should not change to respect backward compatibility.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005782 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005783 was correctly parsed but parsing of subsequent arguments failed.
5784
Vinay Sajip35e3b032008-09-01 14:33:59 +00005785- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005786 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5787 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5788 when given a tuple of classes as second argument, were looking up
5789 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5790 type object.
5791
Neal Norwitz18aa3882008-08-24 05:04:52 +00005792- Fix crashes on memory allocation failure found with failmalloc.

5935-----------------
5936
Guido van Rossumf8402962008-08-20 15:01:50 +00005937- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5938 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5939 extensions do not automatically benefit from the class attribute
5940 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5941 to their tp_flags field if they care. This is a backwards
5942 compatibility feature; in 3.0, all types will use the cache by
5943 default.
5944
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005945- Keyword arguments can now follow starred arguments. (``f(a, *args,
5946 keyword=23)`` is now valid syntax.)

Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005951- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5952 by denying s# to parse objects that have a releasebuffer procedure,
5953 and introducing s*.

Georg Brandl1e13ea92008-08-11 09:07:59 +00005955- Issue #3537: Fix an assertion failure when an empty but presized dict
5956 object was stored in the freelist.
5957
Mark Dickinsonb6467572008-08-04 21:30:09 +00005958- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5959 ValueError consistently across platforms.
5960
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005961- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5962 (64bit Unix, for example), unichr() would truncate its argument and return
5963 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5964
Neal Norwitze7d8be82008-07-31 17:17:14 +00005965- Apply security patches from Apple.

5968 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5969
Antoine Pitrou92f82162008-07-25 22:22:08 +00005970- Issue #1819: function calls with several named parameters are now on
5971 average 35% faster (as measured by pybench).
5972
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005973- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5974 the python debugger steps into a class statement: the free variables (local
5975 variables defined in an outer scope) would be deleted from the outer scope.
5976
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005977- Issue #2620: Overflow checking when allocating or reallocating memory
5978 was not always being done properly in some python types and extension
5979 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5980 all been updated to perform better checks and places in the code that
5981 would previously leak memory on the error path when such an allocation
5982 failed have been fixed.

5988
Benjamin Petersone977ad42008-08-20 01:42:01 +00005989- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5990 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5991
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005992- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5993 version reported by these tools does not necessarily follow the python
5994 version numbering scheme, so the module is less strict when parsing it.
5995
Nick Coghlanf70385a2008-08-18 12:42:46 +00005996- Issue #2235: Added Py3k warnings for types which will become unhashable
5997 under the stricter __hash__ inheritance rules in 3.0. Several types
5998 which did not meet the rules for hash invariants and were already
5999 unhashable in 3.0 have now been explicitly flagged as unhashable in
6000 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,

Brett Cannonbf3157b2008-08-14 05:00:03 +00006034- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6035 since mimetools itself is deprecated. Because modules are cached, all
6036 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6037
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006038- Issue #3134: shutil referenced undefined WindowsError symbol.

6047 a MemoryError rather than silently stop the iteration.
6048
Guido van Rossum59ce9012008-08-09 14:55:34 +00006049- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6050 to _sre.compile() will now be rejected. This should not affect anybody
6051 since the re.compile() function never generates invalid re-bytecode.
6052
Skip Montanaroa032bf42008-08-08 22:52:51 +00006053- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

6055 it wasn't initialized during instantiation.
6056
Brett Cannon3aa2a492008-08-06 22:28:09 +00006057- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6058 the reload() built-in has been removed.
6059
Brett Cannon7e30b672008-08-04 21:52:25 +00006060- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00006072 asking for a specific length. This problem only affected files opened
6073 using the new "io" module, not the built-in open() function.

6099 file name rather than a ZipInfo instance, so files are extracted with
6100 mode 0600 rather than 000 under Unix.
6101
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006102- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6103 argument in python 2.5, this broke code that subclassed Popen to include its

6115 interaction with the tp_hash slot (added in 2.6b2) are now documented
6116
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006117- Issue #643841: The language reference now provides more detailed
6118 coverage of the lookup process for special methods. The disclaimers
6119 regarding lack of coverage of new-style classes have also been
6120 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006128Core and Builtins
6129-----------------
6130
Georg Brandl3e483f62008-07-16 22:57:41 +00006131- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6132 its methods now allow for items objects that can be converted to
6133 an integer using operator.index().
6134
Mark Dickinson64b7e502008-07-16 09:40:03 +00006135- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6136 produced a ValueError instead of giving the correct float.
6137
Eric Smitha5fa5a22008-07-16 00:11:49 +00006138- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6139 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6140
Mark Dickinson7103aa42008-07-15 19:08:33 +00006141- Issue #3008: the float type has a new instance method 'float.hex'
6142 and a new class method 'float.fromhex' to convert floating-point
6143 numbers to and from hexadecimal strings, respectively.
6144
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006145- Issue #2235: __hash__ is once again inherited by default. To allow
6146 collections.Hashable to remain meaningful in the presence of the
6147 default hash implementation (object.__hash__), it is now possible
6148 to explicit block inheritance of hash by setting __hash__=None at
6149 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6150 level.
6151
Nick Coghlanb028f502008-07-13 14:52:36 +00006152- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6153 the parent module cannot be found while performing an absolute import.
6154 This means that an incorrectly defined __package__ attribute will
6155 now only prevent relative imports in that module rather than causing
6156 all imports from that module to fail.
6157
Nick Coghlan14ff9942008-07-08 14:21:42 +00006158- Issue #2517: Allow unicode messages in Exceptions again by correctly
6159 bypassing the instance dictionary when looking up __unicode__ on
6160 new-style classes.
6161
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006162- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6163 set to a custom object whose write() method happens to install
6164 another file in sys.stdout.
6165
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006166- Issue #3088: Corrected a race condition in classes derived from
6167 threading.local: the first member set by a thread could be saved in
6168 another thread's dictionary.
6169
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006170- Issue #3004: Minor change to slice.indices(): the start and stop
6171 arguments are now treated identically, making the behaviour easier
6172 to describe and understand. For example, slice(None, -10,
6173 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6174 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6175 10, -1).
6176
Georg Brandl278fc502008-07-19 12:46:12 +00006177- Issue #3219: Calling a function with repeated keyword arguments,
6178 f(a=2, a=23), would not cause a syntax error. This was a regression
6179 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006180
Georg Brandl278fc502008-07-19 12:46:12 +00006181- Issue #2862: Make int and float freelist management consistent with
6182 other freelists. Changes their CompactFreeList apis into
6183 ClearFreeList apis and calls them via gc.collect().

6187
Thomas Heller57adf222008-08-14 19:10:48 +00006188- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6189 api functions without holding the GIL, which could lead to a fatal
6190 error when they failed.
6191
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006192- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6206 a valid dlerror() message.
6207
Thomas Heller2bad6572008-07-15 17:19:50 +00006208- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6209 incomplete structure was created.
6210

6214
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006215- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006216
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006217- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6218 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006219 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006220 content-length. The problem had been corrected in the 2.4 branch, but never
6221 merged into trunk.
6222
Georg Brandle78fbcc2008-07-05 10:13:36 +00006223- Issue #2663: add filtering capability to shutil.copytree().

6628 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006629 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006630
6631 This is controlled by the configure argument ``--with-universal-archs``:
6632
6633 - ``--with-universal-archs=all``: install 4-way universal
6634
6635 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6636
6637 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6638
6639 This option should be used in combination with ``--enable-universalsdk=``.
6640
6641 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 +00006691- Issue #1631171: Re-implement the 'warnings' module in C (the
6692 original Python code has been kept as backup). This will allow for
6693 using the 'warning's machinery in such places as the parser where
6694 use of pure Python code is not possible. Both the ``showarning()``
6695 and ``formatwarning()`` gain an optional 'line' argument which is
6696 not called by default for backwards-compatibility reasons. Setting
6697 ``warnings.showwarning()`` to an implementation that lacks support
6698 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006761- Issue #2550: The approach used by client/server code for obtaining
6762 ports to listen on in network-oriented tests has been refined in an
6763 effort to facilitate running multiple instances of the entire
6764 regression test suite in parallel without issue.
6765 test_support.bind_port() has been fixed such that it will always
6766 return a unique port -- which wasn't always the case with the
6767 previous implementation, especially if socket options had been set
6768 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6769 new implementation of bind_port() will actually raise an exception
6770 if it is passed an AF_INET/SOCK_STREAM socket with either the
6771 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6772 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6773 the socket it's been passed. This currently only applies to
6774 Windows. This option prevents any other sockets from binding to the
6775 host/port we've bound to, thus removing the possibility of the
6776 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6777 when a second SOCK_STREAM socket binds and accepts to a host/port
6778 that's already been bound by another socket. The optional preferred
6779 port parameter to bind_port() has been removed. Under no
6780 circumstances should tests be hard coding ports!
6781
6782 test_support.find_unused_port() has also been introduced, which will
6783 pass a temporary socket object to bind_port() in order to obtain an
6784 unused port. The temporary socket object is then closed and
6785 deleted, and the port is returned. This method should only be used
6786 for obtaining an unused port in order to pass to an external program
6787 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6788 a parameter to a server-oriented class that doesn't give you direct
6789 access to the underlying socket used.
6790
6791 Finally, test_support.HOST has been introduced, which should be used
6792 for the host argument of any relevant socket calls (i.e. bind and
6793 connect).

7068-----------------
7069
Fred Drakea8ee94b2008-03-01 02:45:07 +00007070- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007071 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007072
Georg Brandlad61bc82008-02-23 15:11:18 +00007073- Issue #2067: file.__exit__() now calls subclasses' close() method.
7074
7075- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007076
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007077- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007078 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007079
Eric Smitha73fbe72008-02-23 03:09:44 +00007080- Added the future_builtins module, which contains hex() and oct().
7081 These are the PEP 3127 version of these functions, designed to be
7082 compatible with the hex() and oct() builtins from Python 3.0. They
7083 differ slightly in their output formats from the existing, unchanged
7084 Python 2.6 builtins. The expected usage of the future_builtins
7085 module is:
7086 from future_builtins import hex, oct
7087
Eric Smith7ef40bf2008-02-20 23:34:22 +00007088- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7089 exponents for exponents with absolute value < 100. Follows C99
7090 standard. This is a change on Windows, which would use 3 digits.
7091 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7092 so that any alterations it does to the resulting string will be
7093 available in stringlib/formatter.h (for float.__format__).
7094
Eric Smith5a3c1352008-02-19 13:21:56 +00007095- Implemented PEP 3101, Advanced String Formatting. This adds a new
7096 builtin format(); a format() method for str and unicode; a
7097 __format__() method to object, str, unicode, int, long, float, and
7098 datetime; the class string.Formatter; and the C API
7099 PyObject_Format().
7100
Georg Brandl3ee81df2008-05-17 18:14:43 +00007101- Fixed several potential crashes, all caused by specially crafted
7102 __del__ methods exploiting objects in temporarily inconsistent
7103 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007104
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007105- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007106 prevent a possible crash: an Abstract Base Class would try to access
7107 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007108
Georg Brandl3ee81df2008-05-17 18:14:43 +00007109- Fixed repr() and str() of complex numbers with infinity or nan as
7110 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007111
Georg Brandl3ee81df2008-05-17 18:14:43 +00007112- Clear all free lists during a gc.collect() of the highest generation
7113 in order to allow pymalloc to free more arenas. Python may give back
7114 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007115
Georg Brandl3ee81df2008-05-17 18:14:43 +00007116- Issue #2045: Fix an infinite recursion triggered when printing a
7117 subclass of collections.defaultdict, if its default_factory is set
7118 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007119
Christian Heimesf75dbef2008-02-08 00:11:31 +00007120- Fixed a minor memory leak in dictobject.c. The content of the free
7121 list was not freed on interpreter shutdown.
7122
Georg Brandl21e99f42010-03-07 15:23:59 +00007123- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007124 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007125
Georg Brandl3ee81df2008-05-17 18:14:43 +00007126- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7127 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007128 to compact the internal free lists of pre-allocted ints and floats.
7129
Georg Brandl3ee81df2008-05-17 18:14:43 +00007130- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7131 calls. Python expected the return type int but the fork familie
7132 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007133
Georg Brandl3ee81df2008-05-17 18:14:43 +00007134- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7135 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00007136
Georg Brandl3ee81df2008-05-17 18:14:43 +00007137- Issue #2025: Add tuple.count() and tuple.index() methods to comply
7138 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00007139
Georg Brandl3ee81df2008-05-17 18:14:43 +00007140- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
7141 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00007142
Georg Brandl3ee81df2008-05-17 18:14:43 +00007143- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7144 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007145
Georg Brandl3ee81df2008-05-17 18:14:43 +00007146- Patch #1473257: generator objects gain a gi_code attribute. This is
7147 the same object as the func_code attribute of the function that
7148 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007149
Georg Brandl3ee81df2008-05-17 18:14:43 +00007150- Issue #1920: "while 0" statements were completely removed by the
7151 compiler, even in the presence of an "else" clause, which is
7152 supposed to be run when the condition is false. Now the compiler
7153 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007154
Guido van Rossumeead05f2008-01-24 18:21:02 +00007155- A few crashers fixed: weakref_in_del.py (issue #1377858);
7156 loosing_dict_ref.py (issue #1303614, test67.py);
7157 borrowed_ref_[34].py (not in tracker).
7158
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007159- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007160 suppressed while an extension is loaded by calling SetErrorMode in
7161 dynload_win.c. The error is still reported properly.
7162
Georg Brandl3ee81df2008-05-17 18:14:43 +00007163- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007164 several extension methods and modules do not work without unicode
7165 support.
7166
Georg Brandl26543b12008-01-21 18:36:51 +00007167- Issue #1882: when compiling code from a string, encoding cookies in the
7168 second line of code were not always recognized correctly.
7169
Georg Brandl14404b62008-01-19 19:27:05 +00007170- Issue #1679: "0x" was taken as a valid integer literal.
7171
Georg Brandl6caad7d2008-01-26 14:19:22 +00007172- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007173 added.
7174
Christian Heimesc94e2b52008-01-14 04:13:37 +00007175- sys.float_info / PyFloat_GetInfo: The floating point information
7176 object was converted from a dict to a specialized structseq object.
7177
Georg Brandl3ee81df2008-05-17 18:14:43 +00007178- Patch #1816: Added sys.flags structseq. It exposes the status of
7179 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007180
Georg Brandl3ee81df2008-05-17 18:14:43 +00007181- Objects/structseq.c: Implemented new structseq representation. The
7182 patch makes structseqs (e.g. the return value of os.stat) more
7183 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007184
Georg Brandl3ee81df2008-05-17 18:14:43 +00007185- Patch #1700288: added a type attribute cache that caches method
7186 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007187
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007188- Bug #1776: __import__() no longer accepts filenames on any platform.
7189 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007190
Georg Brandlaed6c662008-01-07 17:25:53 +00007191- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7192
Georg Brandl3ee81df2008-05-17 18:14:43 +00007193- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7194 envvar and sys.dont_write_bytecode attribute. All these can be set
7195 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007196
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197- Improve some exception messages when Windows fails to load an
7198 extension module. Now we get for example '%1 is not a valid Win32
7199 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007200
Georg Brandl3ee81df2008-05-17 18:14:43 +00007201- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007203- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7204 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007205
Christian Heimes0a8143f2007-12-18 23:22:54 +00007206- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007207 and INF. float("nan"), float("inf") and float("-inf") now work on
7208 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007209
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210- Compiler now generates simpler and faster code for dictionary
7211 literals. The oparg for BUILD_MAP now indicates an estimated
7212 dictionary size. There is a new opcode, STORE_MAP, for adding
7213 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007214
Georg Brandl3ee81df2008-05-17 18:14:43 +00007215- Issue #1638: %zd configure test fails on Linux.

7221 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007222
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007223- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007224 SystemError.
7225
Nick Coghlanef01d822007-12-03 12:55:17 +00007226- PEP 366: Allow explicit relative imports when executing modules
7227 inside packages with the -m switch via a new module level
7228 __package__ attribute.
7229
Georg Brandl3ee81df2008-05-17 18:14:43 +00007230- Issue #1402: Fix a crash on exit, when another thread is still
7231 running, and if the deallocation of its frames somehow calls the
7232 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007233

Georg Brandl3ee81df2008-05-17 18:14:43 +00007247- Issue #1265: Fix a problem with sys.settrace, if the tracing
7248 function uses a generator expression when at the same time the
7249 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007250
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007251- sets and frozensets now have an isdisjoint() method.
7252
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007253- optimize the performance of builtin.sum().
7254
Neal Norwitz44f326e2007-10-05 05:29:17 +00007255- Fix warnings found by the new version of the Coverity checker.
7256
Georg Brandl21e99f42010-03-07 15:23:59 +00007257- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007258 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7259 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007260
Georg Brandl3ee81df2008-05-17 18:14:43 +00007261- Issue #1686386: Tuple's tp_repr did not take into account the
7262 possibility of having a self-referential tuple, which is possible
7263 from C code. Nor did object's tp_str consider that a type's tp_str
7264 could do something that could lead to an inifinite recursion.
7265 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7266 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007267
Georg Brandl3ee81df2008-05-17 18:14:43 +00007268- Issue #1164: It was possible to trigger deadlock when using the
7269 'print' statement to write to a file since the GIL was not released
7270 as needed. Now PyObject_Print() does the right thing along with
7271 various tp_print implementations of the built-in types and those in
7272 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007273
Georg Brandl3ee81df2008-05-17 18:14:43 +00007274- Issue #1147: Exceptions were directly allowing string exceptions in
7275 their throw() method even though string exceptions no longer
7276 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007277

Brett Cannon1e534b52007-09-07 04:18:30 +00007281- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007282 PyObject_Call() never calling back out to Python code to trigger
7283 recursion depth updates/checks. Required the creation of a static
7284 RuntimeError instance in case normalizing an exception put the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007302 __*__ attributes. (Some already existed, e.g., __doc__ and
7303 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007304
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007305- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00007312 "except E as target:". This is to provide forwards compatibility
7313 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007314
Brett Cannon229cee22007-05-05 01:34:02 +00007315- Deprecate BaseException.message as per PEP 352.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007321 setting a plain string, ie don't expand to single letter identifiers.
7322
Raymond Hettinger13936692007-04-11 18:40:58 +00007323- Request #1191699: Slices can now be pickled.

7333
Guido van Rossum143b5642007-03-23 04:58:42 +00007334- Bug #1683368: The object.__init__() and object.__new__() methods are
7335 now stricter in rejecting excess arguments. The only time when
7336 either allows excess arguments is when it is not overridden and the
7337 other one is. For backwards compatibility, when both are
7338 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007339 warning later). Also, type.__init__() insists on the same signature
7340 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007341
Georg Brandl3ee81df2008-05-17 18:14:43 +00007342- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7343 object to complex using its __complex__() method before falling back
7344 to the __float__() method. Therefore, the functions in the cmath
7345 module now can operate on objects that define a __complex__()
7346 method.

7363
Georg Brandl7b9c5552007-03-12 14:30:05 +00007364- Bug #1678647: write a newline after printing an exception in any
7365 case, even when converting the value to a string failed.
7366
Georg Brandl871f1bc2007-03-12 13:17:36 +00007367- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007368 its argument, if it exists. If not, it will work like before. This
7369 allows customizing the output of dir() in the presence of a
7370 __getattr__().

7380 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007381
Georg Brandlaa2321b2007-03-07 00:40:28 +00007382- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007383 makes the filenames the warning module prints much more sensible
7384 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007385

Georg Brandl0fca97a2007-03-05 22:28:08 +00007397- Patch #1674228: when assigning a slice (old-style), check for the
7398 sq_ass_slice instead of the sq_slice slot.
7399
Georg Brandl3ee81df2008-05-17 18:14:43 +00007400- When printing an unraisable error, don't print exceptions. before

8029 incompatibility since it never made sense with ordinary subclasses
8030 -- the failure just occurred later, with a more cumbersome
8031 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008312- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8313 with RFC 3207 and forgets any knowledge obtained from the server not
8314 obtained from the TLS negotiation itself. Patch contributed by Bill
8315 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008316
Georg Brandl3ee81df2008-05-17 18:14:43 +00008317- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008318 that the SMTP.starttls() caller no longer needs to call ehlo()
8319 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008320 does not claim to support starttls. Adds the
8321 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

8402 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8403 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00008405

Georg Brandl3ee81df2008-05-17 18:14:43 +00008420 time so that opening a database previously created with the DB_DUP
8421 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8422 opens. Specifically: dictionary assignment to a DB object will
8423 replace all values for a given key when the database allows
8424 duplicate values. DB users should use DB.put(k, v) when they want
8425 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008426

8432 characters with ASCII value less than 32. Also, it correctly quotes
8433 dots only if they occur on a single line, as opposed to the previous
8434 behavior of quoting dots if they are the second character of any
8435 line.

8758-----
8759
Georg Brandl3ee81df2008-05-17 18:14:43 +00008760- Unified naming convention for free lists and their limits. All free
8761 lists in Object/ are named ``free_list``, the counter ``numfree``
8762 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8763 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008764
Georg Brandl3ee81df2008-05-17 18:14:43 +00008765- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8766 to ``PyTuple_SetItem``, it can be used to populate a brand new
8767 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008768
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008769- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008770
Georg Brandl3ee81df2008-05-17 18:14:43 +00008771- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8772 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8773 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008774
8775- Patch #1720595: add T_BOOL to the range of structmember types.
8776
8777- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8778 ``PyFloat_GetInfo()`` to the float API.
8779
Georg Brandl3ee81df2008-05-17 18:14:43 +00008780- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8781 of w# format code incorrectly truncated the length to an int, even
8782 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8783 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008784
Georg Brandl3ee81df2008-05-17 18:14:43 +00008785- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8786 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008787
Georg Brandl3ee81df2008-05-17 18:14:43 +00008788- PEP 3123: Provide forward compatibility with Python 3.0, while
8789 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8790 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008791
Georg Brandl3ee81df2008-05-17 18:14:43 +00008792- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8793 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008794
8795- Patch #1733960: Allow T_LONGLONG to accept ints.
8796
8797- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8798
Christian Heimes000a0742008-01-03 22:16:32 +00008799- Added a new API function ``PyImport_ImportModuleNoBlock``.
8800
Georg Brandl6caad7d2008-01-26 14:19:22 +00008801- Bug #1637022: Prefix AST symbols with _Py_.
8802
8803- Fix some leftovers from the conversion from int to Py_ssize_t
8804 (relevant to strings and sequences of more than 2**31 items).
8805
8806- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8807 outside of pystate.c and should not be necessary.
8808
Georg Brandl3ee81df2008-05-17 18:14:43 +00008809- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8810 absolute imports. In earlier versions they might have used relative
8811 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008812
Georg Brandl3ee81df2008-05-17 18:14:43 +00008813- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8814 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008815
Georg Brandl3ee81df2008-05-17 18:14:43 +00008816- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8817 macro so it can be used as an expression.

8822
Georg Brandl3ee81df2008-05-17 18:14:43 +00008823- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8824 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8825 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8826 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008827
Georg Brandl3ee81df2008-05-17 18:14:43 +00008828- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
8829 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008841- Removed the macfs module. It had been deprecated since Python 2.5.
8842 This lead to the deprecation of macostools.touched() as it relied
8843 solely on macfs and was a no-op under OS X.
