959
960- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
961 and later systems as is currently done for Python 3.x installers.
962 For 2.7.7 only, we will provide three installers:
963 the legacy deprecated 10.3+ 32-bit-only format;
964 the newer 10.5+ 32-bit-only format;
965 and the unchanged 10.6+ 64-/32-bit format.
966 Although binary installers will no longer be available from
967 python.org as of 2.7.8, it will still be possible to build from
968 source on 10.3.9 and 10.4 systems if necessary.

2351 32-bit-only installer Pythons on systems with Xcode 4 (currently
2352 OS X 10.8, 10.7, and optionally 10.6).
2353 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2354 * Since Xcode 4 removes ppc support, extension module builds now
2355 check for ppc compiler support and by default remove ppc and
2356 ppc64 archs when they are not available.
2357 * Extension module builds now revert to using system installed
2358 headers and libs (/usr and /System/Library) if the SDK used
2359 to build the interpreter is not installed or has moved.
2360 * Try to avoid building extension modules with deprecated
2361 and problematic Apple llvm-gcc compiler. If original compiler
2362 is not available, use clang instead by default.

2728 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002729 compiler optimizing the check away. Also fix similar overflow checks
2730 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01002800 has left two versions of customize_compiler, the original in
2801 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002806- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2807 Distutils-based packages with C extension modules may fail because
2808 Apple has removed gcc-4.2, the version used to build python.org
2809 64-bit/32-bit Pythons. If the user does not explicitly override
2810 the default C compiler by setting the CC environment variable,
2811 Distutils will now attempt to compile extension modules with clang
2812 if gcc-4.2 is required but not found. Also as a convenience, if
2813 the user does explicitly set CC, substitute its value as the default
2814 compiler in the Distutils LDSHARED configuration variable for OS X.
2815 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2816 SDK, neither of which are available in Xcode 4. This change does not
2817 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003067- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3068 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3069 interpreter process. This could cause failures in non-Distutils subprocesses
3070 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003071 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003072 deployment target only in the environment of each build subprocess. It is
3073 still possible to globally override the default by setting
3074 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3075 greater or equal to the default value, the value with which the interpreter
3076 was built.

3105 updating the check interval, so if the user decreases the check interval,
3106 the ticker doesn't have to wind down to zero from the old starting point
3107 before the new interval takes effect. And if the user increases the
3108 interval, it makes sure the new limit takes effect right away rather have an
3109 early task switch before recognizing the new interval.

4107 This prevents user-created self-referencing ordered dictionaries from
4108 becoming permanently uncollectable GC garbage. The downside is that
4109 removing __del__ means that the internal doubly-linked list has to wait for
4110 GC collection rather than freeing memory immediately when the refcnt drops
4111 to zero.

4568
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004569- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4570 start byte and the continuation byte(s) are now considered invalid, instead
4571 of the number of bytes specified by the start byte.
4572 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4573 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4574 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
4575 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004583- Issue #8748: Fix two issues with comparisons between complex and integer
4584 objects. (1) The comparison could incorrectly return True in some cases
4585 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4586 (2) The comparison raised an OverflowError for large integers, leading
4587 to unpredictable exceptions when combining integers and complex objects
4588 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00004590- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004727- Issue #1533: Fix inconsistency in range function argument processing: any
4728 non-float non-integer argument is now converted to an integer (if possible)
4729 using its __int__ method. Previously, only small arguments were treated this
4730 way; larger arguments (those whose __int__ was outside the range of a C long)
4731 would produce a TypeError.

Georg Brandlfee0f442010-05-22 21:26:21 +00004739 ``PyMarshal_ReadLastObjectFromFile``, which doesn't bring any noticeable
Antoine Pitrou18e63fb2010-04-21 22:53:29 +00004740 benefit compared to the dynamic memory allocation fallback. Patch by
4741 Charles-François Natali.

4766 messages when accessing undefined class attributes because of the cheap
4767 inheritance with the underlying socket object. The cheap inheritance has been
4768 deprecated.

Georg Brandlfee0f442010-05-22 21:26:21 +00004781- Issue #8567: Fix precedence of signals in Decimal module: when a Decimal
4782 operation raises multiple signals and more than one of those signals is
4783 trapped, the specification determines the order in which the signals should be
4784 handled. In many cases this order wasn't being followed, leading to the wrong
4785 Python exception being raised.
Mark Dickinson4f96f5f2010-05-04 14:25:50 +00004786

4954
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004955- Issue #7301: Add environment variable $PYTHONWARNINGS.
4956
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004957- Issue #8329: Don't return the same lists from select.select when no fds are
4958 changed.
4959
Georg Brandlfee0f442010-05-22 21:26:21 +00004960- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004961 on 64-bit machines. The shift count for either left or right shift is
4962 permitted to be up to sys.maxsize.
4963
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004964- Ensure that tokenization of identifiers is not affected by locale.
4965
Georg Brandlfee0f442010-05-22 21:26:21 +00004966- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004967
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004968- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4969
Georg Brandlfee0f442010-05-22 21:26:21 +00004970- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4971 with a non-empty format string. This is an effort to future-proof user
4972 code. If a derived class does not currently implement __format__ but later
4973 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004974 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004975 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004976
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004977- Issue #8268: Old-style classes (not just instances) now support weak
4978 references.
4979
Georg Brandlfee0f442010-05-22 21:26:21 +00004980- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
4981 is set.
Victor Stinner6cbf90f2010-03-25 00:21:53 +00004982
Victor Stinnerc7790ed2010-03-22 12:36:28 +00004983- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +00004984
Benjamin Peterson96545892010-03-21 20:21:00 +00004985- Issue #6474: Make error message from passing an inadequate number of keyword
4986 arguments to a function correct.
4987
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00004988- Issue #8164: Don't allow lambda functions to have a docstring.
4989
Victor Stinner66644262010-03-10 22:30:19 +00004990- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004991 (SIGINT). If an error occurs while importing the site module, the error is
4992 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00004993 module.
4994
Collin Winter001a3952010-03-18 21:54:01 +00004995- Code objects now support weak references.

R. David Murray661303f2010-04-13 20:57:40 +00005000- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
5001
Antoine Pitrouf9de5342010-04-05 21:35:07 +00005002- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00005003 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
5004 `ssl.OPENSSL_VERSION_NUMBER`.
Antoine Pitrouf9de5342010-04-05 21:35:07 +00005005
Benjamin Peterson76a23c12010-04-04 23:23:22 +00005006- Issue #8310: Allow dis to examine new style classes.
5007
Georg Brandlfee0f442010-05-22 21:26:21 +00005008- Issue #8257: The Decimal construct now accepts a float instance directly,
5009 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00005010
5011 >>> Decimal(1.1)
5012 Decimal('1.100000000000000088817841970012523233890533447265625')
5013
Raymond Hettinger34c35b22010-04-03 10:22:00 +00005014- collections.Counter() now supports a subtract() method.
5015
Georg Brandlfee0f442010-05-22 21:26:21 +00005016- The functools module now has a total_ordering() class decorator to simplify
5017 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00005018
Georg Brandlfee0f442010-05-22 21:26:21 +00005019- The functools module also adds cmp_to_key() as a tool to transition old-style
5020 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00005021
Georg Brandlfee0f442010-05-22 21:26:21 +00005022- Issue #8294: The Fraction constructor now accepts Decimal and float instances
5023 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00005024
Georg Brandlfee0f442010-05-22 21:26:21 +00005025- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5026 InvalidOperation instead of returning False. (Comparisons involving a quiet
5027 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5028 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005029
Georg Brandlfee0f442010-05-22 21:26:21 +00005030- Issue #2531: Comparison operations between floats and Decimal instances now
5031 return a result based on the numeric values of the operands; previously they
5032 returned an arbitrary result based on the relative ordering of id(float) and
5033 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00005034
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005035- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005036 argument `-` which tells it to read files to compile from stdin. Each line is
5037 read on demand and the named file is compiled immediately. (Original patch by
5038 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005039
Georg Brandlfee0f442010-05-22 21:26:21 +00005040- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
5041 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00005043- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
5044 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00005045 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00005046
Georg Brandlfee0f442010-05-22 21:26:21 +00005047- Comparisons using one of <, <=, >, >= between a complex instance and a
5048 Fractions instance now raise TypeError instead of returning True/False. This
5049 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5050 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00005051
Michael Foorde6410c52010-03-29 20:04:23 +00005052- Addition of ``WeakSet`` to the ``weakref`` module.

5060
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005061- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00005062 didn't support chflags() (for example ZFS under FreeBSD). The error is now
5063 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +00005064
Florent Xicluna9e7a4c92010-03-22 16:07:38 +00005065- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
5066 deprecated.
5067
Georg Brandlfee0f442010-05-22 21:26:21 +00005068- Issue #7860: platform.uname now reports the correct 'machine' type when Python
5069 is running in WOW64 mode on 64 bit Windows.
R. David Murrayc9d1a782010-03-22 15:55:09 +00005070

5075 existing at the same time, causing a Unicode error when configuration code
5076 attempted to sort the existing loggers.
Vinay Sajip31e928e2010-03-22 13:02:28 +00005077
Georg Brandlfee0f442010-05-22 21:26:21 +00005078- Issue #8200: logging: Handle errors when multiprocessing is not fully loaded
5079 when logging occurs.

Matthias Klose358e7ff2010-03-15 13:42:23 +00005100
Georg Brandlfee0f442010-05-22 21:26:21 +00005101- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been set

Vinay Sajipecfa08f2010-03-12 09:16:10 +00005105- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00005106 for ``TimedRotatingFileHandler`` by using the modification time of an existing
5107 log file to compute the next rollover time. If the log file does not exist,
5108 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00005109
Georg Brandlba83f822010-03-14 09:50:54 +00005110- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

5117
Georg Brandlba83f822010-03-14 09:50:54 +00005118- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
5119 a base64 transfer-encoded payload *after* decoding it; it no longer does.
5120 This is a behavior change, so email's minor version number is now bumped, to
5121 version 4.0.2, for the 2.7 release.

Mark Dickinson4846a8e2010-04-03 14:05:10 +00005149- Issue #8300: When passing a non-integer argument to struct.pack with any
5150 integer format code, struct.pack first attempts to convert the non-integer
5151 using its __index__ method. If that method is non-existent or raises
5152 TypeError it goes on to try the __int__ method, as described below.
5153
Georg Brandlba83f822010-03-14 09:50:54 +00005154- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
5155 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
5156 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00005157 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
5158 inconsistent: __int__ was used for some integer codes but not for others, and
5159 the set of integer codes for which it was used differed between native packing
5160 and standard packing.)

5427 numeric strings corresponding to subnormal values,
5428 (3) a memory leak for some values large enough to cause overflow, and
5429 (4) a number of flaws that could lead to incorrectly rounded results.

5564Core and Builtins
5565-----------------
5566
Georg Brandlba83f822010-03-14 09:50:54 +00005567- The ``__complex__()`` method is now looked up on the class of instances to
5568 make it consistent with other special methods.

5572
Mark Dickinson1b34d252010-01-01 17:27:30 +00005573- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005574 DeprecationWarning when passed a float argument where an integer was expected.
5575 These functions and methods now raise TypeError instead. The majority of the
5576 effects of this change are in the extension modules, but some core functions
5577 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5578 and many unicode/str methods.

5590
Georg Brandlba83f822010-03-14 09:50:54 +00005591- Issue #1811: Improve accuracy and cross-platform consistency for true division
5592 of integers: the result of a/b is now correctly rounded for ints a and b (at
5593 least on IEEE 754 platforms), and in particular does not depend on the
5594 internal representation of a long.

5602
Georg Brandlba83f822010-03-14 09:50:54 +00005603 These executables now work properly with the arch(1) command: ``arch -ppc
5604 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00005760- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5761 decimal string that's guaranteed to round back to x under correct rounding
5762 (with round-half-to-even rounding mode). Previously it gave a string based on
5763 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5764 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5765 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005766
Georg Brandlba83f822010-03-14 09:50:54 +00005767- Issue #7117: On almost all platforms: float-to-string and string-to-float
5768 conversions within Python are now correctly rounded. Places these conversions
5769 occur include: str for floats and complex numbers; the float and complex
5770 constructors; old-style and new-style numeric formatting; serialization and
5771 deserialization of floats and complex numbers using marshal, pickle and json;
5772 parsing of float and imaginary literals in Python code; Decimal-to-float
5773 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005774
Georg Brandlba83f822010-03-14 09:50:54 +00005775 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5776 providing correctly-rounded strtod and dtoa C functions. This code is
5777 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5778 the C compiler. There may be a small number of platforms on which correct
5779 operation of this code cannot be guaranteed, so the code is not used: notably,
5780 this applies to platforms where the C double format is not IEEE 754 binary64,
5781 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5782 and Python's configure script is unable to determine how to change the FPU
5783 precision. On these platforms conversions use the platform strtod and dtoa,
5784 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005786- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5787 uses the correctly-rounded string <-> float conversions described above (when
5788 available), and so produces correctly rounded results that will display nicely
5789 under the float repr. There are two related small changes: (1) round now
5790 accepts any class with an ``__index__()`` method for its second argument (but
5791 no longer accepts floats for the second argument), and (2) an excessively
5792 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5793 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005935
Georg Brandlba83f822010-03-14 09:50:54 +00005936 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5937 (2) parsing of strings representing infinities and nans was locale aware; and
5938 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00005939
Georg Brandlba83f822010-03-14 09:50:54 +00005940- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5941 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5942 but with at least one decimal point and with a default precision
5943 of 12. Previously, the behavior the same but with a default precision of 6.
5944 This more closely matches ``str()``, and reduces surprises when adding
5945 alignment flags to the empty presentation type. This also affects the new
5946 complex.__format__ in the same way.
5947
5948- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5949 classtype's, even if it was None. property now inserts the __doc__ into the
5950 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00006011 untrackable objects are not tracked by the garbage collector. This can reduce
6012 the size of collections and therefore the garbage collection overhead on

6020 internal representation of integers, for performance reasons. Base 2**30 is
6021 enabled by default on 64-bit machines. Add --enable-big-digits option to
6022 configure, which overrides the default. Add sys.long_info structseq to
6023 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00006124- Issue #4597: Fixed exception handling when the __exit__ function of a context
6125 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00006126
Georg Brandlba83f822010-03-14 09:50:54 +00006127- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00006128
Georg Brandlba83f822010-03-14 09:50:54 +00006129- Issue #4445: Replace ``sizeof(PyStringObject)`` with
6130 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
6131 instances. On a typical machine this saves 3 bytes of memory (on average) per
6132 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00006133
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00006134- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
6135 interpreter to abort ("Fatal Python error: Could not reset the stack!")
6136 instead of throwing a MemoryError.
6137
Georg Brandlba83f822010-03-14 09:50:54 +00006138- Issue #3689: The list reversed iterator now supports __length_hint__ instead
6139 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00006140
Benjamin Petersonc078f922008-11-21 22:27:24 +00006141- Issue #4367: Python would segfault during compiling when the unicodedata
6142 module couldn't be imported and \N escapes were present.
6143
Georg Brandlba83f822010-03-14 09:50:54 +00006144- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6145 file objects with closefd=False. The file descriptor is still kept open but
6146 the file object behaves like a closed file. The ``FileIO`` object also got a
6147 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00006148
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00006149- Issue #4348: Some bytearray methods returned that didn't cause any change to
6150 the bytearray, returned the same bytearray instead of a copy.
6151
Georg Brandlba83f822010-03-14 09:50:54 +00006152- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +00006153
Benjamin Peterson273c2332008-11-17 22:39:09 +00006154- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
6155
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00006156- Issue #4048: The parser module now correctly validates relative imports.
6157
Benjamin Petersondcee09d2008-10-31 02:16:05 +00006158- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
6159 exec statement.
6160
Georg Brandlba83f822010-03-14 09:50:54 +00006161- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
6162 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00006163
Benjamin Petersonbdca9422008-10-26 20:21:13 +00006164- Issue #4209: Enabling unicode_literals and the print_function in the same
6165 __future__ import didn't work.
6166
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006167- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00006168 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00006169
Georg Brandlba83f822010-03-14 09:50:54 +00006170- On windows, ``os.chdir()`` given unicode was not working if
6171 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6172 this code path is really executed because I cannot move to such directory on
6173 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00006174
Georg Brandlba83f822010-03-14 09:50:54 +00006175- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6176 element is temporarily replaced with an equivalent frozenset. But the
6177 eventual KeyError would always report the empty ``frozenset()`` as the missing
6178 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00006179
Georg Brandlba83f822010-03-14 09:50:54 +00006180- Issue #4509: Various issues surrounding resize of bytearray objects to which
6181 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00006182
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00006183- Issue #4748: Lambda generators no longer return a value.
6184
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +00006185- Issue #3582: Use native TLS functions on Windows
6186
Gregory P. Smithae91d092009-03-02 05:13:57 +00006187- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
6188
Georg Brandlba83f822010-03-14 09:50:54 +00006189- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
6190 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00006191
Matthias Klose91a3b9e2009-04-05 21:19:13 +00006192- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
6193 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00006194
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00006195- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
6196 returned them on 64bit platforms.
6197
Walter Dörwalded960ac2009-05-03 22:36:33 +00006198- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
6199 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6200 step. This avoids problems with counting UTF-8 bytes that ignores the effect
6201 of using the replace error handler in PyUnicode_DecodeUTF8().
6202
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006203- Issue #3739: The unicode-internal encoder now reports the number of characters
6204 consumed like any other encoder (instead of the number of bytes).
6205
Georg Brandlba83f822010-03-14 09:50:54 +00006206- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
6207 allocator will be automatically disabled when running under Valgrind. This
6208 gives improved memory leak detection when running under Valgrind, while taking
6209 advantage of pymalloc at other times.

Tarek Ziadéa5076a22009-11-29 22:20:30 +00006234- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
6235 ownership when the group is not forced, because the group may be different
6236 from the user's group and inherit from its container when the test is run.
6237

Georg Brandlba83f822010-03-14 09:50:54 +00006278- Issue #6816: runpy now provides a run_path function that allows Python code to
6279 execute file paths that refer to source or compiled Python files as well as
6280 zipfiles, directories and other valid sys.path entries that contain a
Nick Coghlan49868cb2009-11-15 07:30:34 +00006281 __main__.py file. This allows applications that run other Python scripts to
6282 support the same flexibility as the CPython command line itself.
6283
Georg Brandlba83f822010-03-14 09:50:54 +00006284- Issue #7318: multiprocessing now uses a timeout when it fails to establish a
6285 connection with another process, rather than looping endlessly. The default
6286 timeout is 20 seconds, which should be amply sufficient for local connections.

Antoine Pitrouaec41242009-11-02 11:34:27 +00006303 a modification is done through it. This fixes inconsistencies and test

7497 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007600- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7601 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7602 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7603 ``printf`` function, whereas PyString_FromFormat has an independent
7604 implementation and uses "%zd" on all platforms for size_t values.
7605 This makes a difference on win64, where ``printf`` needs "%Id" to display
7606 64bit values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00007625- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00007626 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
7627 mechanism. In the process, fix a bug where isinstance() and issubclass(),

7629 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
7630 type object.

7775-----------------
7776
Guido van Rossumf8402962008-08-20 15:01:50 +00007777- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7778 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7779 extensions do not automatically benefit from the class attribute
7780 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7781 to their tp_flags field if they care. This is a backwards
7782 compatibility feature; in 3.0, all types will use the cache by
7783 default.
7784
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007785- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00007798- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7799 ValueError consistently across platforms.
7800
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007801- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7802 (64bit Unix, for example), unichr() would truncate its argument and return
7803 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

7814 the python debugger steps into a class statement: the free variables (local
7815 variables defined in an outer scope) would be deleted from the outer scope.
7816
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007817- Issue #2620: Overflow checking when allocating or reallocating memory
7818 was not always being done properly in some python types and extension
7819 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7820 all been updated to perform better checks and places in the code that
7821 would previously leak memory on the error path when such an allocation
7822 failed have been fixed.

7831
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007832- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7833 version reported by these tools does not necessarily follow the python
7834 version numbering scheme, so the module is less strict when parsing it.
7835
Nick Coghlanf70385a2008-08-18 12:42:46 +00007836- Issue #2235: Added Py3k warnings for types which will become unhashable
7837 under the stricter __hash__ inheritance rules in 3.0. Several types
7838 which did not meet the rules for hash invariants and were already
7839 unhashable in 3.0 have now been explicitly flagged as unhashable in
7840 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,

Brett Cannonbf3157b2008-08-14 05:00:03 +00007874- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7875 since mimetools itself is deprecated. Because modules are cached, all
7876 subsequent imports of rfc822 will not raise a visible DeprecationWarning.

7898 the reload() built-in has been removed.
7899
Brett Cannon7e30b672008-08-04 21:52:25 +00007900- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007912 asking for a specific length. This problem only affected files opened
7913 using the new "io" module, not the built-in open() function.

7939 file name rather than a ZipInfo instance, so files are extracted with
7940 mode 0600 rather than 000 under Unix.
7941
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00007942- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

7955 interaction with the tp_hash slot (added in 2.6b2) are now documented
7956
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007957- Issue #643841: The language reference now provides more detailed
7958 coverage of the lookup process for special methods. The disclaimers
7959 regarding lack of coverage of new-style classes have also been
7960 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007968Core and Builtins
7969-----------------
7970
Georg Brandl3e483f62008-07-16 22:57:41 +00007971- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7972 its methods now allow for items objects that can be converted to
7973 an integer using operator.index().
7974
Mark Dickinson64b7e502008-07-16 09:40:03 +00007975- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7976 produced a ValueError instead of giving the correct float.
7977
Eric Smitha5fa5a22008-07-16 00:11:49 +00007978- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7979 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7980
Mark Dickinson7103aa42008-07-15 19:08:33 +00007981- Issue #3008: the float type has a new instance method 'float.hex'
7982 and a new class method 'float.fromhex' to convert floating-point
7983 numbers to and from hexadecimal strings, respectively.
7984
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007985- Issue #2235: __hash__ is once again inherited by default. To allow
7986 collections.Hashable to remain meaningful in the presence of the
7987 default hash implementation (object.__hash__), it is now possible
7988 to explicit block inheritance of hash by setting __hash__=None at
7989 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7990 level.
7991
Nick Coghlanb028f502008-07-13 14:52:36 +00007992- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7993 the parent module cannot be found while performing an absolute import.
7994 This means that an incorrectly defined __package__ attribute will
7995 now only prevent relative imports in that module rather than causing
7996 all imports from that module to fail.
7997
Nick Coghlan14ff9942008-07-08 14:21:42 +00007998- Issue #2517: Allow unicode messages in Exceptions again by correctly
7999 bypassing the instance dictionary when looking up __unicode__ on
8000 new-style classes.
8001
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00008002- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
8003 set to a custom object whose write() method happens to install
8004 another file in sys.stdout.
8005
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00008006- Issue #3088: Corrected a race condition in classes derived from
8007 threading.local: the first member set by a thread could be saved in
8008 another thread's dictionary.
8009
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008010- Issue #3004: Minor change to slice.indices(): the start and stop
8011 arguments are now treated identically, making the behaviour easier
8012 to describe and understand. For example, slice(None, -10,
8013 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8014 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8015 10, -1).
8016
Georg Brandl278fc502008-07-19 12:46:12 +00008017- Issue #3219: Calling a function with repeated keyword arguments,
8018 f(a=2, a=23), would not cause a syntax error. This was a regression
8019 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008020
Georg Brandl278fc502008-07-19 12:46:12 +00008021- Issue #2862: Make int and float freelist management consistent with
8022 other freelists. Changes their CompactFreeList apis into
8023 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00008024

8027
Thomas Heller57adf222008-08-14 19:10:48 +00008028- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
8029 api functions without holding the GIL, which could lead to a fatal
8030 error when they failed.
8031
Martin v. Löwisaabf4042008-08-02 07:20:25 +00008032- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

8041 ForkingPickler.register() to resolve conflict with ctypes.

8046 a valid dlerror() message.
8047
Thomas Heller2bad6572008-07-15 17:19:50 +00008048- Issue #3258: Fixed a crash when a ctypes POINTER type to an
8049 incomplete structure was created.
8050

8054
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008055- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00008056
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008057- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8058 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008059 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008060 content-length. The problem had been corrected in the 2.4 branch, but never
8061 merged into trunk.
8062
Georg Brandle78fbcc2008-07-05 10:13:36 +00008063- Issue #2663: add filtering capability to shutil.copytree().

Georg Brandl5cc774e2008-06-11 20:28:06 +00008467 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00008468
8469 This is controlled by the configure argument ``--with-universal-archs``:
8470
8471 - ``--with-universal-archs=all``: install 4-way universal
8472
8473 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
8474
8475 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
8476
8477 This option should be used in combination with ``--enable-universalsdk=``.
8478
8479 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 +00008528- Issue #1631171: Re-implement the 'warnings' module in C (the
8529 original Python code has been kept as backup). This will allow for
8530 using the 'warning's machinery in such places as the parser where
8531 use of pure Python code is not possible. Both the ``showarning()``
8532 and ``formatwarning()`` gain an optional 'line' argument which is
8533 not called by default for backwards-compatibility reasons. Setting
8534 ``warnings.showwarning()`` to an implementation that lacks support
8535 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00008560- The getpass module has been improved on Unix. It now uses /dev/tty
8561 by default and uses stderr instead of stdout. A GetPassWarning is
8562 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008598- Issue #2550: The approach used by client/server code for obtaining
8599 ports to listen on in network-oriented tests has been refined in an
8600 effort to facilitate running multiple instances of the entire
8601 regression test suite in parallel without issue.
8602 test_support.bind_port() has been fixed such that it will always
8603 return a unique port -- which wasn't always the case with the
8604 previous implementation, especially if socket options had been set
8605 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8606 new implementation of bind_port() will actually raise an exception
8607 if it is passed an AF_INET/SOCK_STREAM socket with either the
8608 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8609 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8610 the socket it's been passed. This currently only applies to
8611 Windows. This option prevents any other sockets from binding to the
8612 host/port we've bound to, thus removing the possibility of the
8613 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8614 when a second SOCK_STREAM socket binds and accepts to a host/port
8615 that's already been bound by another socket. The optional preferred
8616 port parameter to bind_port() has been removed. Under no
8617 circumstances should tests be hard coding ports!
8618
8619 test_support.find_unused_port() has also been introduced, which will
8620 pass a temporary socket object to bind_port() in order to obtain an
8621 unused port. The temporary socket object is then closed and
8622 deleted, and the port is returned. This method should only be used
8623 for obtaining an unused port in order to pass to an external program
8624 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8625 a parameter to a server-oriented class that doesn't give you direct
8626 access to the underlying socket used.
8627
8628 Finally, test_support.HOST has been introduced, which should be used
8629 for the host argument of any relevant socket calls (i.e. bind and
8630 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008631

8905-----------------
8906
Fred Drakea8ee94b2008-03-01 02:45:07 +00008907- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00008908 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00008909
Georg Brandlad61bc82008-02-23 15:11:18 +00008910- Issue #2067: file.__exit__() now calls subclasses' close() method.
8911
8912- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00008913
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008914- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00008915 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00008916
Eric Smitha73fbe72008-02-23 03:09:44 +00008917- Added the future_builtins module, which contains hex() and oct().
8918 These are the PEP 3127 version of these functions, designed to be
8919 compatible with the hex() and oct() builtins from Python 3.0. They
8920 differ slightly in their output formats from the existing, unchanged
8921 Python 2.6 builtins. The expected usage of the future_builtins
8922 module is:
8923 from future_builtins import hex, oct
8924
Eric Smith7ef40bf2008-02-20 23:34:22 +00008925- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8926 exponents for exponents with absolute value < 100. Follows C99
8927 standard. This is a change on Windows, which would use 3 digits.
8928 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8929 so that any alterations it does to the resulting string will be
8930 available in stringlib/formatter.h (for float.__format__).
8931
Eric Smith5a3c1352008-02-19 13:21:56 +00008932- Implemented PEP 3101, Advanced String Formatting. This adds a new
8933 builtin format(); a format() method for str and unicode; a
8934 __format__() method to object, str, unicode, int, long, float, and
8935 datetime; the class string.Formatter; and the C API
8936 PyObject_Format().
8937
Georg Brandl3ee81df2008-05-17 18:14:43 +00008938- Fixed several potential crashes, all caused by specially crafted
8939 __del__ methods exploiting objects in temporarily inconsistent
8940 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008941
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008942- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008943 prevent a possible crash: an Abstract Base Class would try to access
8944 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008945
Georg Brandl3ee81df2008-05-17 18:14:43 +00008946- Fixed repr() and str() of complex numbers with infinity or nan as
8947 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00008948
Georg Brandl3ee81df2008-05-17 18:14:43 +00008949- Clear all free lists during a gc.collect() of the highest generation
8950 in order to allow pymalloc to free more arenas. Python may give back
8951 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008952
Georg Brandl3ee81df2008-05-17 18:14:43 +00008953- Issue #2045: Fix an infinite recursion triggered when printing a
8954 subclass of collections.defaultdict, if its default_factory is set
8955 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008956
Christian Heimesf75dbef2008-02-08 00:11:31 +00008957- Fixed a minor memory leak in dictobject.c. The content of the free
8958 list was not freed on interpreter shutdown.
8959
Georg Brandl21e99f42010-03-07 15:23:59 +00008960- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008961 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008962
Georg Brandl3ee81df2008-05-17 18:14:43 +00008963- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8964 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008965 to compact the internal free lists of pre-allocted ints and floats.
8966
Georg Brandl3ee81df2008-05-17 18:14:43 +00008967- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8968 calls. Python expected the return type int but the fork familie
8969 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008970
Georg Brandl3ee81df2008-05-17 18:14:43 +00008971- Issue #1678380: Fix a bug that identifies 0j and -0j when they
8972 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008973
Georg Brandl3ee81df2008-05-17 18:14:43 +00008974- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8975 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008976
Georg Brandl3ee81df2008-05-17 18:14:43 +00008977- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8978 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008979
Georg Brandl3ee81df2008-05-17 18:14:43 +00008980- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8981 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008982
Georg Brandl3ee81df2008-05-17 18:14:43 +00008983- Patch #1473257: generator objects gain a gi_code attribute. This is
8984 the same object as the func_code attribute of the function that
8985 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008986
Georg Brandl3ee81df2008-05-17 18:14:43 +00008987- Issue #1920: "while 0" statements were completely removed by the
8988 compiler, even in the presence of an "else" clause, which is
8989 supposed to be run when the condition is false. Now the compiler
8990 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008991
Guido van Rossumeead05f2008-01-24 18:21:02 +00008992- A few crashers fixed: weakref_in_del.py (issue #1377858);
8993 loosing_dict_ref.py (issue #1303614, test67.py);
8994 borrowed_ref_[34].py (not in tracker).
8995
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008996- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008997 suppressed while an extension is loaded by calling SetErrorMode in
8998 dynload_win.c. The error is still reported properly.
8999
Georg Brandl3ee81df2008-05-17 18:14:43 +00009000- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009001 several extension methods and modules do not work without unicode
9002 support.
9003
Georg Brandl26543b12008-01-21 18:36:51 +00009004- Issue #1882: when compiling code from a string, encoding cookies in the
9005 second line of code were not always recognized correctly.
9006
Georg Brandl14404b62008-01-19 19:27:05 +00009007- Issue #1679: "0x" was taken as a valid integer literal.
9008
Georg Brandl6caad7d2008-01-26 14:19:22 +00009009- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009010 added.
9011
Christian Heimesc94e2b52008-01-14 04:13:37 +00009012- sys.float_info / PyFloat_GetInfo: The floating point information
9013 object was converted from a dict to a specialized structseq object.
9014
Georg Brandl3ee81df2008-05-17 18:14:43 +00009015- Patch #1816: Added sys.flags structseq. It exposes the status of
9016 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009017
Georg Brandl3ee81df2008-05-17 18:14:43 +00009018- Objects/structseq.c: Implemented new structseq representation. The
9019 patch makes structseqs (e.g. the return value of os.stat) more
9020 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009021
Georg Brandl3ee81df2008-05-17 18:14:43 +00009022- Patch #1700288: added a type attribute cache that caches method
9023 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009024
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009025- Bug #1776: __import__() no longer accepts filenames on any platform.
9026 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009027
Georg Brandlaed6c662008-01-07 17:25:53 +00009028- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9029
Georg Brandl3ee81df2008-05-17 18:14:43 +00009030- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9031 envvar and sys.dont_write_bytecode attribute. All these can be set
9032 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009033
Georg Brandl3ee81df2008-05-17 18:14:43 +00009034- Improve some exception messages when Windows fails to load an
9035 extension module. Now we get for example '%1 is not a valid Win32
9036 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009037
Georg Brandl3ee81df2008-05-17 18:14:43 +00009038- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009040- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9041 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009042
Christian Heimes0a8143f2007-12-18 23:22:54 +00009043- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009044 and INF. float("nan"), float("inf") and float("-inf") now work on
9045 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009046
Georg Brandl3ee81df2008-05-17 18:14:43 +00009047- Compiler now generates simpler and faster code for dictionary
9048 literals. The oparg for BUILD_MAP now indicates an estimated
9049 dictionary size. There is a new opcode, STORE_MAP, for adding
9050 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00009051
Georg Brandl3ee81df2008-05-17 18:14:43 +00009052- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009057- Issue #1538: Avoid copying string in split/rsplit if the split char
9058 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009059
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009060- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009061 SystemError.
9062
Nick Coghlanef01d822007-12-03 12:55:17 +00009063- PEP 366: Allow explicit relative imports when executing modules
9064 inside packages with the -m switch via a new module level
9065 __package__ attribute.
9066
Georg Brandl3ee81df2008-05-17 18:14:43 +00009067- Issue #1402: Fix a crash on exit, when another thread is still
9068 running, and if the deallocation of its frames somehow calls the
9069 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009070

9080 file can now be directly executed by passing their name to the
9081 interpreter. The directory/zipfile is automatically inserted as the
9082 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009083
Georg Brandl3ee81df2008-05-17 18:14:43 +00009084- Issue #1265: Fix a problem with sys.settrace, if the tracing
9085 function uses a generator expression when at the same time the
9086 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009087
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009088- sets and frozensets now have an isdisjoint() method.
9089
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009090- optimize the performance of builtin.sum().
9091
Neal Norwitz44f326e2007-10-05 05:29:17 +00009092- Fix warnings found by the new version of the Coverity checker.
9093
Georg Brandl21e99f42010-03-07 15:23:59 +00009094- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009095 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9096 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009097
Georg Brandl3ee81df2008-05-17 18:14:43 +00009098- Issue #1686386: Tuple's tp_repr did not take into account the
9099 possibility of having a self-referential tuple, which is possible
9100 from C code. Nor did object's tp_str consider that a type's tp_str
9101 could do something that could lead to an inifinite recursion.
9102 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9103 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009104
Georg Brandl3ee81df2008-05-17 18:14:43 +00009105- Issue #1164: It was possible to trigger deadlock when using the
9106 'print' statement to write to a file since the GIL was not released
9107 as needed. Now PyObject_Print() does the right thing along with
9108 various tp_print implementations of the built-in types and those in
9109 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009110
Georg Brandl3ee81df2008-05-17 18:14:43 +00009111- Issue #1147: Exceptions were directly allowing string exceptions in
9112 their throw() method even though string exceptions no longer
9113 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009114
Georg Brandl3ee81df2008-05-17 18:14:43 +00009115- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00009118- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009119 PyObject_Call() never calling back out to Python code to trigger
9120 recursion depth updates/checks. Required the creation of a static
9121 RuntimeError instance in case normalizing an exception put the
9122 recursion check value past its limit. Fixes crashers
9123 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009124

Neal Norwitz0ac60192007-05-27 04:08:54 +00009138- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009139 __*__ attributes. (Some already existed, e.g., __doc__ and
9140 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009141
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009142- Add -3 option to the interpreter to warn about features that are

9147
Collin Winter62903052007-05-18 23:11:24 +00009148- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009149 "except E as target:". This is to provide forwards compatibility
9150 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009151
Brett Cannon229cee22007-05-05 01:34:02 +00009152- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00009157- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009158 setting a plain string, ie don't expand to single letter identifiers.
9159
Raymond Hettinger13936692007-04-11 18:40:58 +00009160- Request #1191699: Slices can now be pickled.
9161

9170
Guido van Rossum143b5642007-03-23 04:58:42 +00009171- Bug #1683368: The object.__init__() and object.__new__() methods are
9172 now stricter in rejecting excess arguments. The only time when
9173 either allows excess arguments is when it is not overridden and the
9174 other one is. For backwards compatibility, when both are
9175 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009176 warning later). Also, type.__init__() insists on the same signature
9177 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009178
Georg Brandl3ee81df2008-05-17 18:14:43 +00009179- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9180 object to complex using its __complex__() method before falling back
9181 to the __float__() method. Therefore, the functions in the cmath
9182 module now can operate on objects that define a __complex__()
9183 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009184

9187 same slot names.

9200
Georg Brandl7b9c5552007-03-12 14:30:05 +00009201- Bug #1678647: write a newline after printing an exception in any
9202 case, even when converting the value to a string failed.
9203
Georg Brandl871f1bc2007-03-12 13:17:36 +00009204- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009205 its argument, if it exists. If not, it will work like before. This
9206 allows customizing the output of dir() in the presence of a
9207 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009208
Collin Winter276887b2007-03-12 16:11:39 +00009209- Patch #922167: Python no longer segfaults when faced with infinitely
9210 self-recursive reload() calls (as reported by bug #742342).

9216 parthensized forms. This means complex(repr(x)) now works instead of
9217 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009218
Georg Brandlaa2321b2007-03-07 00:40:28 +00009219- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009220 makes the filenames the warning module prints much more sensible
9221 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009222

Georg Brandl0fca97a2007-03-05 22:28:08 +00009234- Patch #1674228: when assigning a slice (old-style), check for the
9235 sq_ass_slice instead of the sq_slice slot.
9236
Georg Brandl3ee81df2008-05-17 18:14:43 +00009237- When printing an unraisable error, don't print exceptions. before

9248 created a weakref on itself during a __del__ call for new-style
9249 classes (classic classes still have the bug).

9861
Georg Brandl3ee81df2008-05-17 18:14:43 +00009862- unittest now verifies more of its assumptions. In particular,
9863 TestCase and TestSuite subclasses (not instances) are no longer
9864 accepted in TestSuite.addTest(). This should cause no
9865 incompatibility since it never made sense with ordinary subclasses
9866 -- the failure just occurred later, with a more cumbersome
9867 exception.

10136 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +000010137
Georg Brandl3ee81df2008-05-17 18:14:43 +000010138- The implementation of UnicodeError objects has been simplified

Georg Brandl3ee81df2008-05-17 18:14:43 +000010147- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +000010148 that the SMTP.starttls() caller no longer needs to call ehlo()
10149 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +000010150 does not claim to support starttls. Adds the
10151 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +000010194- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +000010195 works as expected. ``mmap.find`` also takes an optional ``end``

10232 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Georg Brandl3ee81df2008-05-17 18:14:43 +000010250 time so that opening a database previously created with the DB_DUP
10251 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10252 opens. Specifically: dictionary assignment to a DB object will
10253 replace all values for a given key when the database allows
10254 duplicate values. DB users should use DB.put(k, v) when they want
10255 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010256

10262 characters with ASCII value less than 32. Also, it correctly quotes
10263 dots only if they occur on a single line, as opposed to the previous
10264 behavior of quoting dots if they are the second character of any
10265 line.
Georg Brandl4aef7272007-03-13 22:49:43 +000010266

10593-----
10594
Georg Brandl3ee81df2008-05-17 18:14:43 +000010595- Unified naming convention for free lists and their limits. All free
10596 lists in Object/ are named ``free_list``, the counter ``numfree``
10597 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
10598 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +000010599
Georg Brandl3ee81df2008-05-17 18:14:43 +000010600- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
10601 to ``PyTuple_SetItem``, it can be used to populate a brand new
10602 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010603
Vinay Sajipb7edfc42008-04-02 21:10:23 +000010604- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +000010605
Georg Brandl3ee81df2008-05-17 18:14:43 +000010606- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
10607 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
10608 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010609
10610- Patch #1720595: add T_BOOL to the range of structmember types.
10611
10612- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
10613 ``PyFloat_GetInfo()`` to the float API.
10614
Georg Brandl3ee81df2008-05-17 18:14:43 +000010615- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
10616 of w# format code incorrectly truncated the length to an int, even
10617 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10618 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010619
Georg Brandl3ee81df2008-05-17 18:14:43 +000010620- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
10621 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010622
Georg Brandl3ee81df2008-05-17 18:14:43 +000010623- PEP 3123: Provide forward compatibility with Python 3.0, while
10624 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
10625 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010626
Georg Brandl3ee81df2008-05-17 18:14:43 +000010627- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
10628 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +000010629
10630- Patch #1733960: Allow T_LONGLONG to accept ints.
10631
10632- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
10633
Christian Heimes000a0742008-01-03 22:16:32 +000010634- Added a new API function ``PyImport_ImportModuleNoBlock``.
10635
Georg Brandl6caad7d2008-01-26 14:19:22 +000010636- Bug #1637022: Prefix AST symbols with _Py_.
10637
10638- Fix some leftovers from the conversion from int to Py_ssize_t
10639 (relevant to strings and sequences of more than 2**31 items).
10640
10641- Make _PyGILState_NoteThreadState() static, it was not used anywhere
10642 outside of pystate.c and should not be necessary.
10643
Georg Brandl3ee81df2008-05-17 18:14:43 +000010644- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10645 absolute imports. In earlier versions they might have used relative
10646 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010647
Georg Brandl3ee81df2008-05-17 18:14:43 +000010648- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10649 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +000010650
Georg Brandl3ee81df2008-05-17 18:14:43 +000010651- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
10652 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +000010657- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
10658 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
10659 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
10660 builds.
Christian Heimes95d64472008-02-09 19:55:22 +000010661
Georg Brandl3ee81df2008-05-17 18:14:43 +000010662- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +000010672- buildtools now raises a DeprecationWarning.
10673
Georg Brandl3ee81df2008-05-17 18:14:43 +000010674- Removed the macfs module. It had been deprecated since Python 2.5.
10675 This lead to the deprecation of macostools.touched() as it relied
10676 solely on macfs and was a no-op under OS X.
