Mark Dickinsondbbed042011-09-19 16:38:08 +0100664- Issue #12973: Fix overflow checks that invoked undefined behaviour in
665 int.__pow__. These overflow checks were causing int.__pow__ to produce
666 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100667 compiler optimizing the check away. Also fix similar overflow checks
668 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
669 bugs caused test failures with recent versions of Clang.

681 cleared by the garbage collector. This fixes a segfault when an instance
682 and its type get caught in a reference cycle, and the instance's
683 deallocator calls one of the methods on the type (e.g. when subclassing

739 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100744- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
745 Distutils-based packages with C extension modules may fail because
746 Apple has removed gcc-4.2, the version used to build python.org
747 64-bit/32-bit Pythons. If the user does not explicitly override
748 the default C compiler by setting the CC environment variable,
749 Distutils will now attempt to compile extension modules with clang
750 if gcc-4.2 is required but not found. Also as a convenience, if
751 the user does explicitly set CC, substitute its value as the default
752 compiler in the Distutils LDSHARED configuration variable for OS X.
753 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
754 SDK, neither of which are available in Xcode 4. This change does not
755 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001028- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1029 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1030 interpreter process. This could cause failures in non-Distutils subprocesses
1031 and was unreliable since tests or user programs could modify the interpreter
1032 environment after Distutils set it. Instead, have Distutils set the the
1033 deployment target only in the environment of each build subprocess. It is
1034 still possible to globally override the default by setting
1035 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1036 greater or equal to the default value, the value with which the interpreter
1037 was built.

1066 updating the check interval, so if the user decreases the check interval,
1067 the ticker doesn't have to wind down to zero from the old starting point
1068 before the new interval takes effect. And if the user increases the
1069 interval, it makes sure the new limit takes effect right away rather have an
1070 early task switch before recognizing the new interval.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002485- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2486 start byte and the continuation byte(s) are now considered invalid, instead
2487 of the number of bytes specified by the start byte.
2488 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2489 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

2500 objects. (1) The comparison could incorrectly return True in some cases
2501 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2502 (2) The comparison raised an OverflowError for large integers, leading

2698 operation raises multiple signals and more than one of those signals is
2699 trapped, the specification determines the order in which the signals should be

Georg Brandlfee0f442010-05-22 21:26:21 +00002845- Issue #8625: Turn off optimization in ``--with-pydebug`` builds with gcc.
Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002846 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2847 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2848 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2868Core and Builtins
2869-----------------
2870
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002871- Issue #7301: Add environment variable $PYTHONWARNINGS.
2872
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002873- Issue #8329: Don't return the same lists from select.select when no fds are
2874 changed.
2875
Georg Brandlfee0f442010-05-22 21:26:21 +00002876- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002877 on 64-bit machines. The shift count for either left or right shift is
2878 permitted to be up to sys.maxsize.
2879
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002880- Ensure that tokenization of identifiers is not affected by locale.
2881
Georg Brandlfee0f442010-05-22 21:26:21 +00002882- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002883
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002884- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2885
Georg Brandlfee0f442010-05-22 21:26:21 +00002886- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2887 with a non-empty format string. This is an effort to future-proof user
2888 code. If a derived class does not currently implement __format__ but later
2889 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002890 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002891 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002892
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002893- Issue #8268: Old-style classes (not just instances) now support weak
2894 references.
2895
Georg Brandlfee0f442010-05-22 21:26:21 +00002896- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in case it
2897 is set.

Benjamin Peterson96545892010-03-21 20:21:00 +00002901- Issue #6474: Make error message from passing an inadequate number of keyword
2902 arguments to a function correct.
2903
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002904- Issue #8164: Don't allow lambda functions to have a docstring.
2905
Victor Stinner66644262010-03-10 22:30:19 +00002906- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002907 (SIGINT). If an error occurs while importing the site module, the error is
2908 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002909 module.

Antoine Pitrouf9de5342010-04-05 21:35:07 +00002918- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00002919 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
2920 `ssl.OPENSSL_VERSION_NUMBER`.

Benjamin Peterson76a23c12010-04-04 23:23:22 +00002922- Issue #8310: Allow dis to examine new style classes.
2923
Georg Brandlfee0f442010-05-22 21:26:21 +00002924- Issue #8257: The Decimal construct now accepts a float instance directly,
2925 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002926
2927 >>> Decimal(1.1)
2928 Decimal('1.100000000000000088817841970012523233890533447265625')
2929
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002930- collections.Counter() now supports a subtract() method.
2931
Georg Brandlfee0f442010-05-22 21:26:21 +00002932- The functools module now has a total_ordering() class decorator to simplify
2933 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002934
Georg Brandlfee0f442010-05-22 21:26:21 +00002935- The functools module also adds cmp_to_key() as a tool to transition old-style
2936 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002937
Georg Brandlfee0f442010-05-22 21:26:21 +00002938- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2939 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002940
Georg Brandlfee0f442010-05-22 21:26:21 +00002941- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2942 InvalidOperation instead of returning False. (Comparisons involving a quiet
2943 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2944 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002945
Georg Brandlfee0f442010-05-22 21:26:21 +00002946- Issue #2531: Comparison operations between floats and Decimal instances now
2947 return a result based on the numeric values of the operands; previously they
2948 returned an arbitrary result based on the relative ordering of id(float) and
2949 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002950
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002951- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002952 argument `-` which tells it to read files to compile from stdin. Each line is
2953 read on demand and the named file is compiled immediately. (Original patch by
2954 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002955
Georg Brandlfee0f442010-05-22 21:26:21 +00002956- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a
2957 function like a normal call.

Florent Xicluna58b65662010-03-30 16:29:03 +00002959- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2960 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002961 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002962
Georg Brandlfee0f442010-05-22 21:26:21 +00002963- Comparisons using one of <, <=, >, >= between a complex instance and a
2964 Fractions instance now raise TypeError instead of returning True/False. This
2965 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2966 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002967
Michael Foorde6410c52010-03-29 20:04:23 +00002968- Addition of ``WeakSet`` to the ``weakref`` module.

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002977- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002978 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2979 silenced.

Florent Xicluna9e7a4c92010-03-22 16:07:38 +00002981- Issue #7703: ctypes supports both buffer() and memoryview(). The former is
2982 deprecated.
2983
Georg Brandlfee0f442010-05-22 21:26:21 +00002984- Issue #7860: platform.uname now reports the correct 'machine' type when Python

Vinay Sajipecfa08f2010-03-12 09:16:10 +00003021- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00003022 for ``TimedRotatingFileHandler`` by using the modification time of an existing
3023 log file to compute the next rollover time. If the log file does not exist,
3024 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +00003025
Georg Brandlba83f822010-03-14 09:50:54 +00003026- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Georg Brandlba83f822010-03-14 09:50:54 +00003034- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
3035 a base64 transfer-encoded payload *after* decoding it; it no longer does.
3036 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003065- Issue #8300: When passing a non-integer argument to struct.pack with any
3066 integer format code, struct.pack first attempts to convert the non-integer
3067 using its __index__ method. If that method is non-existent or raises
3068 TypeError it goes on to try the __int__ method, as described below.
3069
Georg Brandlba83f822010-03-14 09:50:54 +00003070- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3071 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3072 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003073 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3074 inconsistent: __int__ was used for some integer codes but not for others, and
3075 the set of integer codes for which it was used differed between native packing

3308 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003309 library would return a bogus result; on Solaris, it was possible to crash the

3330 returning NULL. The macro now returns a statically allocated empty string
3331 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003384 file position when calling `truncate()`. It would previously change the file
3385 position to the given argument, which goes against the tradition of

3389 class used to represent files stored inside an archive. The new
3390 implementation is significantly faster and can be wrapped in a
3391 ``io.BufferedReader`` object for more speedups. It also solves an issue
3392 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3405 encoded string for them. This ensures that the upload and register commands
3406 send the correct values to PyPI without any error.

3488
Mark Dickinson1b34d252010-01-01 17:27:30 +00003489- Issue #5080: A number of functions and methods previously produced a

3491 These functions and methods now raise TypeError instead. The majority of the
3492 effects of this change are in the extension modules, but some core functions
3493 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3494 and many unicode/str methods.

3508 of integers: the result of a/b is now correctly rounded for ints a and b (at
3509 least on IEEE 754 platforms), and in particular does not depend on the
3510 internal representation of a long.

3518
Georg Brandlba83f822010-03-14 09:50:54 +00003519 These executables now work properly with the arch(1) command: ``arch -ppc
3520 python`` will start a universal binary version of python in PPC mode (unlike

3661 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003662
Georg Brandlba83f822010-03-14 09:50:54 +00003663- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3664 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003665

Georg Brandlba83f822010-03-14 09:50:54 +00003677- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3678 decimal string that's guaranteed to round back to x under correct rounding
3679 (with round-half-to-even rounding mode). Previously it gave a string based on
3680 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3681 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3682 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003683
Georg Brandlba83f822010-03-14 09:50:54 +00003684- Issue #7117: On almost all platforms: float-to-string and string-to-float
3685 conversions within Python are now correctly rounded. Places these conversions
3686 occur include: str for floats and complex numbers; the float and complex
3687 constructors; old-style and new-style numeric formatting; serialization and
3688 deserialization of floats and complex numbers using marshal, pickle and json;
3689 parsing of float and imaginary literals in Python code; Decimal-to-float
3690 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003691
Georg Brandlba83f822010-03-14 09:50:54 +00003692 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3693 providing correctly-rounded strtod and dtoa C functions. This code is
3694 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3695 the C compiler. There may be a small number of platforms on which correct
3696 operation of this code cannot be guaranteed, so the code is not used: notably,
3697 this applies to platforms where the C double format is not IEEE 754 binary64,
3698 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3699 and Python's configure script is unable to determine how to change the FPU
3700 precision. On these platforms conversions use the platform strtod and dtoa,
3701 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003703- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3704 uses the correctly-rounded string <-> float conversions described above (when
3705 available), and so produces correctly rounded results that will display nicely
3706 under the float repr. There are two related small changes: (1) round now
3707 accepts any class with an ``__index__()`` method for its second argument (but
3708 no longer accepts floats for the second argument), and (2) an excessively
3709 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3710 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003852
Georg Brandlba83f822010-03-14 09:50:54 +00003853 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3854 (2) parsing of strings representing infinities and nans was locale aware; and
3855 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003857- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3858 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3859 but with at least one decimal point and with a default precision
3860 of 12. Previously, the behavior the same but with a default precision of 6.
3861 This more closely matches ``str()``, and reduces surprises when adding
3862 alignment flags to the empty presentation type. This also affects the new
3863 complex.__format__ in the same way.
3864
3865- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3866 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00003928 untrackable objects are not tracked by the garbage collector. This can reduce

3937 internal representation of integers, for performance reasons. Base 2**30 is
3938 enabled by default on 64-bit machines. Add --enable-big-digits option to

4025
Georg Brandl6425a2f2008-12-28 11:54:53 +00004026- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004027 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00004028
Skip Montanarof205c132008-12-23 03:30:15 +00004029- Added test case to ensure attempts to read from a file opened for writing
4030 fail.
4031
Georg Brandlba83f822010-03-14 09:50:54 +00004032- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
4033 elapsed times, not only when some objects are uncollectable/unreachable.

Georg Brandlba83f822010-03-14 09:50:54 +00004046- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4047 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4048 instances. On a typical machine this saves 3 bytes of memory (on average) per
4049 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004051- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
4052 interpreter to abort ("Fatal Python error: Could not reset the stack!")
4053 instead of throwing a MemoryError.
4054
Georg Brandlba83f822010-03-14 09:50:54 +00004055- Issue #3689: The list reversed iterator now supports __length_hint__ instead
4056 of __len__. Behavior now matches other reversed iterators.

Benjamin Petersonc078f922008-11-21 22:27:24 +00004058- Issue #4367: Python would segfault during compiling when the unicodedata
4059 module couldn't be imported and \N escapes were present.
4060
Georg Brandlba83f822010-03-14 09:50:54 +00004061- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4062 file objects with closefd=False. The file descriptor is still kept open but
4063 the file object behaves like a closed file. The ``FileIO`` object also got a
4064 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004066- Issue #4348: Some bytearray methods returned that didn't cause any change to
4067 the bytearray, returned the same bytearray instead of a copy.
4068
Georg Brandlba83f822010-03-14 09:50:54 +00004069- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersondcee09d2008-10-31 02:16:05 +00004075- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

Benjamin Petersonbdca9422008-10-26 20:21:13 +00004081- Issue #4209: Enabling unicode_literals and the print_function in the same
4082 __future__ import didn't work.
4083
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004084- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004085 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004086
Georg Brandlba83f822010-03-14 09:50:54 +00004087- On windows, ``os.chdir()`` given unicode was not working if
4088 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4089 this code path is really executed because I cannot move to such directory on
4090 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004091
Georg Brandlba83f822010-03-14 09:50:54 +00004092- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4093 element is temporarily replaced with an equivalent frozenset. But the
4094 eventual KeyError would always report the empty ``frozenset()`` as the missing
4095 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00004112- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
4113 returned them on 64bit platforms.
4114
Walter Dörwalded960ac2009-05-03 22:36:33 +00004115- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4116 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4117 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4118 of using the replace error handler in PyUnicode_DecodeUTF8().
4119
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004120- Issue #3739: The unicode-internal encoder now reports the number of characters
4121 consumed like any other encoder (instead of the number of bytes).
4122
Georg Brandlba83f822010-03-14 09:50:54 +00004123- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4124 allocator will be automatically disabled when running under Valgrind. This
4125 gives improved memory leak detection when running under Valgrind, while taking
4126 advantage of pymalloc at other times.

5369 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005370 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5371 the tests if DISPLAY is defined but can't be used.

5378 test_warnings have been adjusted to use it, tests for other modules with both
5379 C and Python implementations in the stdlib can be adjusted to use it over
5380 time.

5390 support, which does the conversion.

5492
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005493- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5494 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5495 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5496 ``printf`` function, whereas PyString_FromFormat has an independent
5497 implementation and uses "%zd" on all platforms for size_t values.
5498 This makes a difference on win64, where ``printf`` needs "%Id" to display
5499 64bit values.

5505 object; previously an int would be returned for small values. the __long__
5506 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005516 was correctly parsed but parsing of subsequent arguments failed.
5517
Vinay Sajip35e3b032008-09-01 14:33:59 +00005518- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005519 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5520 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5521 when given a tuple of classes as second argument, were looking up
5522 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5523 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005662What's New in Python 2.6 beta 3?
5663================================
5664
Barry Warsaw07a4a382008-08-21 01:15:08 +00005665*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005666
5667Core and Builtins
5668-----------------
5669
Guido van Rossumf8402962008-08-20 15:01:50 +00005670- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5671 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5672 extensions do not automatically benefit from the class attribute
5673 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5674 to their tp_flags field if they care. This is a backwards
5675 compatibility feature; in 3.0, all types will use the cache by
5676 default.
5677
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005678- Keyword arguments can now follow starred arguments. (``f(a, *args,
5679 keyword=23)`` is now valid syntax.)
5680
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005681- ctypes function pointers that are COM methods have a boolean True
5682 value again.
5683
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005684- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5685 by denying s# to parse objects that have a releasebuffer procedure,
5686 and introducing s*.
5687
Georg Brandl1e13ea92008-08-11 09:07:59 +00005688- Issue #3537: Fix an assertion failure when an empty but presized dict
5689 object was stored in the freelist.
5690
Mark Dickinsonb6467572008-08-04 21:30:09 +00005691- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5692 ValueError consistently across platforms.
5693
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005694- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5695 (64bit Unix, for example), unichr() would truncate its argument and return
5696 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5697
Neal Norwitze7d8be82008-07-31 17:17:14 +00005698- Apply security patches from Apple.
5699
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005700- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5701 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5702
Antoine Pitrou92f82162008-07-25 22:22:08 +00005703- Issue #1819: function calls with several named parameters are now on
5704 average 35% faster (as measured by pybench).
5705
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005706- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5707 the python debugger steps into a class statement: the free variables (local
5708 variables defined in an outer scope) would be deleted from the outer scope.
5709
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005710- Issue #2620: Overflow checking when allocating or reallocating memory
5711 was not always being done properly in some python types and extension
5712 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5713 all been updated to perform better checks and places in the code that
5714 would previously leak memory on the error path when such an allocation
5715 failed have been fixed.
5716
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005717Library
5718-------
5719
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005720- Issue #3612: Added some missing basic types in ctypes.wintypes.
5721
Benjamin Petersone977ad42008-08-20 01:42:01 +00005722- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5723 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5724
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005725- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5726 version reported by these tools does not necessarily follow the python
5727 version numbering scheme, so the module is less strict when parsing it.
5728
Nick Coghlanf70385a2008-08-18 12:42:46 +00005729- Issue #2235: Added Py3k warnings for types which will become unhashable
5730 under the stricter __hash__ inheritance rules in 3.0. Several types
5731 which did not meet the rules for hash invariants and were already
5732 unhashable in 3.0 have now been explicitly flagged as unhashable in
5733 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5734 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5735
Brett Cannon88f801d2008-08-18 00:46:22 +00005736- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5737 imported into the module but exposed as part of the module's API.
5738
Brett Cannon7b96f072008-08-18 00:41:11 +00005739- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5740
Brett Cannon46225e72008-08-18 00:36:52 +00005741- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5742
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005743- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5744
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005745- Issue #3575: Incremental decoder's decode function now takes bytearray
5746 by using 's*' instead of 't#'.
5747
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005748- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005749 fails unicode conversion on 2nd parameter. (windows only)
5750
Georg Brandl222e2082010-08-01 22:27:39 +00005751- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005752 in a redirect.
5753
Brett Cannonabe423e2008-08-16 21:47:07 +00005754- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005755 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005756
Facundo Batistaeb90b782008-08-16 14:44:07 +00005757- Issue #2776: fixed small issue when handling an URL with double slash
5758 after a 302 response in the case of not going through a proxy.
5759
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005760- Issue #2676: in the email package, content-type parsing was hanging on
5761 pathological input because of quadratic or exponential behaviour of a
5762 regular expression.
5763
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005764- Issue #3476: binary buffered reading through the new "io" library is now
5765 thread-safe.
5766
Brett Cannonbf3157b2008-08-14 05:00:03 +00005767- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5768 since mimetools itself is deprecated. Because modules are cached, all
5769 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5770
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005771- Issue #3134: shutil referenced undefined WindowsError symbol.
5772
Robert Schuppenies14646332008-08-10 11:01:53 +00005773- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5774 menu entries were not deleted.
5775
Brett Cannon83e81842008-08-09 23:30:55 +00005776- Copied the implementation of reduce() to _functools.reduce() to have a
5777 version that did not raise a DeprecationWarning under -3.
5778
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005779- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5780 a MemoryError rather than silently stop the iteration.
5781
Guido van Rossum59ce9012008-08-09 14:55:34 +00005782- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5783 to _sre.compile() will now be rejected. This should not affect anybody
5784 since the re.compile() function never generates invalid re-bytecode.
5785
Skip Montanaroa032bf42008-08-08 22:52:51 +00005786- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5787 upon first access it can be automatically initialized from the csv file if
5788 it wasn't initialized during instantiation.
5789
Brett Cannon3aa2a492008-08-06 22:28:09 +00005790- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5791 the reload() built-in has been removed.
5792
Brett Cannon7e30b672008-08-04 21:52:25 +00005793- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005794 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00005795 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
5796 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
5797 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5798 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5799 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005800
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005801- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5802 raised an AttributeError.
5803
Benjamin Peterson01a24322008-07-28 23:35:27 +00005804- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005805 asking for a specific length. This problem only affected files opened
5806 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005807
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005808- Issue #3449: Update decimal module to use most recent specification
5809 (v. 1.68) and tests (v. 2.58) from IBM.
5810
Georg Brandl222e2082010-08-01 22:27:39 +00005811- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005812

Raymond Hettinger8c664e82008-07-25 18:43:33 +00005814 on a closed shelf.
5815
Georg Brandlf9efabb2008-07-23 15:16:45 +00005816- Deprecate the "ast" parser function aliases.
5817
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005818- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5819
5820- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5821 invalid arguments.
5822
5823- Issue #3302: Fix several crashes when calling locale's gettext functions
5824 with None arguments.
5825
5826- Issue #3389: Allow resolving dotted names for handlers in logging
5827 configuration files.
5828
5829- Deprecate the sunaudio module for removal in Python 3.0.
5830
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005831- Issue #3394: zipfile.writestr sets external attributes when passed a
5832 file name rather than a ZipInfo instance, so files are extracted with
5833 mode 0600 rather than 000 under Unix.
5834
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005835- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5836 argument in python 2.5, this broke code that subclassed Popen to include its
5837 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5845-------------
5846
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005847- Issue #2235: the C API function PyObject_HashNotImplemented and its
5848 interaction with the tp_hash slot (added in 2.6b2) are now documented
5849
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005850- Issue #643841: The language reference now provides more detailed
5851 coverage of the lookup process for special methods. The disclaimers
5852 regarding lack of coverage of new-style classes have also been
5853 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005856What's New in Python 2.6 beta 2?
5857================================
5858
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005859*Release date: 17-Jul-2008*
5860
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005861Core and Builtins
5862-----------------
5863
Georg Brandl3e483f62008-07-16 22:57:41 +00005864- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5865 its methods now allow for items objects that can be converted to
5866 an integer using operator.index().
5867
Mark Dickinson64b7e502008-07-16 09:40:03 +00005868- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5869 produced a ValueError instead of giving the correct float.
5870
Eric Smitha5fa5a22008-07-16 00:11:49 +00005871- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5872 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5873
Mark Dickinson7103aa42008-07-15 19:08:33 +00005874- Issue #3008: the float type has a new instance method 'float.hex'
5875 and a new class method 'float.fromhex' to convert floating-point
5876 numbers to and from hexadecimal strings, respectively.
5877
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005878- Issue #2235: __hash__ is once again inherited by default. To allow
5879 collections.Hashable to remain meaningful in the presence of the
5880 default hash implementation (object.__hash__), it is now possible
5881 to explicit block inheritance of hash by setting __hash__=None at
5882 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5883 level.
5884
Nick Coghlanb028f502008-07-13 14:52:36 +00005885- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5886 the parent module cannot be found while performing an absolute import.
5887 This means that an incorrectly defined __package__ attribute will
5888 now only prevent relative imports in that module rather than causing
5889 all imports from that module to fail.
5890
Nick Coghlan14ff9942008-07-08 14:21:42 +00005891- Issue #2517: Allow unicode messages in Exceptions again by correctly
5892 bypassing the instance dictionary when looking up __unicode__ on
5893 new-style classes.
5894
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005895- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5896 set to a custom object whose write() method happens to install
5897 another file in sys.stdout.
5898
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005899- Issue #3088: Corrected a race condition in classes derived from
5900 threading.local: the first member set by a thread could be saved in
5901 another thread's dictionary.
5902
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005903- Issue #3004: Minor change to slice.indices(): the start and stop
5904 arguments are now treated identically, making the behaviour easier
5905 to describe and understand. For example, slice(None, -10,
5906 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5907 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5908 10, -1).
5909
Georg Brandl278fc502008-07-19 12:46:12 +00005910- Issue #3219: Calling a function with repeated keyword arguments,
5911 f(a=2, a=23), would not cause a syntax error. This was a regression
5912 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005913
Georg Brandl278fc502008-07-19 12:46:12 +00005914- Issue #2862: Make int and float freelist management consistent with
5915 other freelists. Changes their CompactFreeList apis into
5916 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00005921- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5922 api functions without holding the GIL, which could lead to a fatal
5923 error when they failed.
5924
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005925- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

5934 ForkingPickler.register() to resolve conflict with ctypes.
5935
Vinay Sajip51e65192008-07-18 09:01:10 +00005936- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

5939 a valid dlerror() message.
5940
Thomas Heller2bad6572008-07-15 17:19:50 +00005941- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5942 incomplete structure was created.

6359
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006360- On MacOS X it is now possible to install the framework in 64-bit
6361 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006362 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006363
6364 This is controlled by the configure argument ``--with-universal-archs``:
6365
6366 - ``--with-universal-archs=all``: install 4-way universal
6367
6368 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6369
6370 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6371
6372 This option should be used in combination with ``--enable-universalsdk=``.
6373
6374 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 +00006410- Issue #2670: Fix a failure in urllib2.build_opener(), when passed
6411 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006412
Christian Heimese74c8f22008-04-19 02:23:57 +00006413- Added kill, terminate and send_signal(sig) to subprocess.Popen.
6414
Georg Brandl3ee81df2008-05-17 18:14:43 +00006415- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
6416 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00006417
Georg Brandl3ee81df2008-05-17 18:14:43 +00006418- Four new methods were added to the math and cmath modules: acosh,

Georg Brandl3ee81df2008-05-17 18:14:43 +00006424- Issue #1631171: Re-implement the 'warnings' module in C (the
6425 original Python code has been kept as backup). This will allow for
6426 using the 'warning's machinery in such places as the parser where
6427 use of pure Python code is not possible. Both the ``showarning()``
6428 and ``formatwarning()`` gain an optional 'line' argument which is
6429 not called by default for backwards-compatibility reasons. Setting
6430 ``warnings.showwarning()`` to an implementation that lacks support
6431 for the ``line`` argument will raise a DeprecationWarning.

Neal Norwitz2b0bea52008-04-25 03:40:17 +00006453- Issue #2682: ctypes callback functions no longer contain a cyclic
Thomas Hellerbf027c42008-04-24 18:14:19 +00006454 reference to themselves.
6455
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006456- The getpass module has been improved on Unix. It now uses /dev/tty
6457 by default and uses stderr instead of stdout. A GetPassWarning is
6458 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00006459

6470 implementation detail of the public ``types`` module, has been
6471 removed and replaced by pure python code.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006473- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006474 extension modules between 32 and 64 bit platforms. See the distutls
6475 build documentation for more information.

6487 so the controlled environment will more closely mirror the typical
6488 script environment. This supports setup.py scripts that refer to
6489 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006494- Issue #2550: The approach used by client/server code for obtaining
6495 ports to listen on in network-oriented tests has been refined in an
6496 effort to facilitate running multiple instances of the entire
6497 regression test suite in parallel without issue.
6498 test_support.bind_port() has been fixed such that it will always
6499 return a unique port -- which wasn't always the case with the
6500 previous implementation, especially if socket options had been set
6501 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6502 new implementation of bind_port() will actually raise an exception
6503 if it is passed an AF_INET/SOCK_STREAM socket with either the
6504 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6505 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6506 the socket it's been passed. This currently only applies to
6507 Windows. This option prevents any other sockets from binding to the
6508 host/port we've bound to, thus removing the possibility of the
6509 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6510 when a second SOCK_STREAM socket binds and accepts to a host/port
6511 that's already been bound by another socket. The optional preferred
6512 port parameter to bind_port() has been removed. Under no
6513 circumstances should tests be hard coding ports!
6514
6515 test_support.find_unused_port() has also been introduced, which will
6516 pass a temporary socket object to bind_port() in order to obtain an
6517 unused port. The temporary socket object is then closed and
6518 deleted, and the port is returned. This method should only be used
6519 for obtaining an unused port in order to pass to an external program
6520 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6521 a parameter to a server-oriented class that doesn't give you direct
6522 access to the underlying socket used.
6523
6524 Finally, test_support.HOST has been introduced, which should be used
6525 for the host argument of any relevant socket calls (i.e. bind and
6526 connect).

6801-----------------
6802
Fred Drakea8ee94b2008-03-01 02:45:07 +00006803- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006804 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006805
Georg Brandlad61bc82008-02-23 15:11:18 +00006806- Issue #2067: file.__exit__() now calls subclasses' close() method.
6807
6808- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00006809
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006810- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006811 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006812
Eric Smitha73fbe72008-02-23 03:09:44 +00006813- Added the future_builtins module, which contains hex() and oct().
6814 These are the PEP 3127 version of these functions, designed to be
6815 compatible with the hex() and oct() builtins from Python 3.0. They
6816 differ slightly in their output formats from the existing, unchanged
6817 Python 2.6 builtins. The expected usage of the future_builtins
6818 module is:
6819 from future_builtins import hex, oct
6820
Eric Smith7ef40bf2008-02-20 23:34:22 +00006821- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6822 exponents for exponents with absolute value < 100. Follows C99
6823 standard. This is a change on Windows, which would use 3 digits.
6824 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6825 so that any alterations it does to the resulting string will be
6826 available in stringlib/formatter.h (for float.__format__).
6827
Eric Smith5a3c1352008-02-19 13:21:56 +00006828- Implemented PEP 3101, Advanced String Formatting. This adds a new
6829 builtin format(); a format() method for str and unicode; a
6830 __format__() method to object, str, unicode, int, long, float, and
6831 datetime; the class string.Formatter; and the C API
6832 PyObject_Format().
6833
Georg Brandl3ee81df2008-05-17 18:14:43 +00006834- Fixed several potential crashes, all caused by specially crafted
6835 __del__ methods exploiting objects in temporarily inconsistent
6836 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006837
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006838- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006839 prevent a possible crash: an Abstract Base Class would try to access
6840 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006841
Georg Brandl3ee81df2008-05-17 18:14:43 +00006842- Fixed repr() and str() of complex numbers with infinity or nan as
6843 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00006844
Georg Brandl3ee81df2008-05-17 18:14:43 +00006845- Clear all free lists during a gc.collect() of the highest generation
6846 in order to allow pymalloc to free more arenas. Python may give back
6847 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006848
Georg Brandl3ee81df2008-05-17 18:14:43 +00006849- Issue #2045: Fix an infinite recursion triggered when printing a
6850 subclass of collections.defaultdict, if its default_factory is set
6851 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006852
Christian Heimesf75dbef2008-02-08 00:11:31 +00006853- Fixed a minor memory leak in dictobject.c. The content of the free
6854 list was not freed on interpreter shutdown.
6855
Georg Brandl21e99f42010-03-07 15:23:59 +00006856- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006857 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006858
Georg Brandl3ee81df2008-05-17 18:14:43 +00006859- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6860 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006861 to compact the internal free lists of pre-allocted ints and floats.
6862
Georg Brandl3ee81df2008-05-17 18:14:43 +00006863- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6864 calls. Python expected the return type int but the fork familie
6865 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006866
Georg Brandl3ee81df2008-05-17 18:14:43 +00006867- Issue #1678380: Fix a bug that identifies 0j and -0j when they
6868 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00006869
Georg Brandl3ee81df2008-05-17 18:14:43 +00006870- Issue #2025: Add tuple.count() and tuple.index() methods to comply
6871 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00006872
Georg Brandl3ee81df2008-05-17 18:14:43 +00006873- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
6874 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00006875
Georg Brandl3ee81df2008-05-17 18:14:43 +00006876- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6877 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006878
Georg Brandl3ee81df2008-05-17 18:14:43 +00006879- Patch #1473257: generator objects gain a gi_code attribute. This is
6880 the same object as the func_code attribute of the function that
6881 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006882
Georg Brandl3ee81df2008-05-17 18:14:43 +00006883- Issue #1920: "while 0" statements were completely removed by the
6884 compiler, even in the presence of an "else" clause, which is
6885 supposed to be run when the condition is false. Now the compiler
6886 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006887
Guido van Rossumeead05f2008-01-24 18:21:02 +00006888- A few crashers fixed: weakref_in_del.py (issue #1377858);
6889 loosing_dict_ref.py (issue #1303614, test67.py);
6890 borrowed_ref_[34].py (not in tracker).
6891
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006892- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006893 suppressed while an extension is loaded by calling SetErrorMode in
6894 dynload_win.c. The error is still reported properly.
6895
Georg Brandl3ee81df2008-05-17 18:14:43 +00006896- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006897 several extension methods and modules do not work without unicode
6898 support.
6899
Georg Brandl26543b12008-01-21 18:36:51 +00006900- Issue #1882: when compiling code from a string, encoding cookies in the
6901 second line of code were not always recognized correctly.
6902
Georg Brandl14404b62008-01-19 19:27:05 +00006903- Issue #1679: "0x" was taken as a valid integer literal.
6904
Georg Brandl6caad7d2008-01-26 14:19:22 +00006905- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006906 added.
6907
Christian Heimesc94e2b52008-01-14 04:13:37 +00006908- sys.float_info / PyFloat_GetInfo: The floating point information
6909 object was converted from a dict to a specialized structseq object.
6910
Georg Brandl3ee81df2008-05-17 18:14:43 +00006911- Patch #1816: Added sys.flags structseq. It exposes the status of
6912 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006913
Georg Brandl3ee81df2008-05-17 18:14:43 +00006914- Objects/structseq.c: Implemented new structseq representation. The
6915 patch makes structseqs (e.g. the return value of os.stat) more
6916 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006917
Georg Brandl3ee81df2008-05-17 18:14:43 +00006918- Patch #1700288: added a type attribute cache that caches method
6919 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006920
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006921- Bug #1776: __import__() no longer accepts filenames on any platform.
6922 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006923

6925
Georg Brandl3ee81df2008-05-17 18:14:43 +00006926- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6927 envvar and sys.dont_write_bytecode attribute. All these can be set
6928 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006929
Georg Brandl3ee81df2008-05-17 18:14:43 +00006930- Improve some exception messages when Windows fails to load an
6931 extension module. Now we get for example '%1 is not a valid Win32
6932 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006933
Georg Brandl3ee81df2008-05-17 18:14:43 +00006934- Bug #1481296: Fixed long(float('nan')) != 0L.

6937 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006938
Christian Heimes0a8143f2007-12-18 23:22:54 +00006939- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006940 and INF. float("nan"), float("inf") and float("-inf") now work on
6941 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006942
Georg Brandl3ee81df2008-05-17 18:14:43 +00006943- Compiler now generates simpler and faster code for dictionary
6944 literals. The oparg for BUILD_MAP now indicates an estimated
6945 dictionary size. There is a new opcode, STORE_MAP, for adding
6946 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006980- Issue #1265: Fix a problem with sys.settrace, if the tracing
6981 function uses a generator expression when at the same time the
6982 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006983
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006984- sets and frozensets now have an isdisjoint() method.

6989
Georg Brandl21e99f42010-03-07 15:23:59 +00006990- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006991 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6992 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006993
Georg Brandl3ee81df2008-05-17 18:14:43 +00006994- Issue #1686386: Tuple's tp_repr did not take into account the
6995 possibility of having a self-referential tuple, which is possible
6996 from C code. Nor did object's tp_str consider that a type's tp_str
6997 could do something that could lead to an inifinite recursion.
6998 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6999 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007000
Georg Brandl3ee81df2008-05-17 18:14:43 +00007001- Issue #1164: It was possible to trigger deadlock when using the

7003 as needed. Now PyObject_Print() does the right thing along with
7004 various tp_print implementations of the built-in types and those in
7005 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007007- Issue #1147: Exceptions were directly allowing string exceptions in
7008 their throw() method even though string exceptions no longer
7009 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007011- Issue #1096: Prevent a segfault from getting the repr of a very
7012 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007013
Brett Cannon1e534b52007-09-07 04:18:30 +00007014- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007015 PyObject_Call() never calling back out to Python code to trigger
7016 recursion depth updates/checks. Required the creation of a static
7017 RuntimeError instance in case normalizing an exception put the
7018 recursion check value past its limit. Fixes crashers
7019 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007034- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007035 __*__ attributes. (Some already existed, e.g., __doc__ and
7036 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007037
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007038- Add -3 option to the interpreter to warn about features that are

7042 calls.
7043
Collin Winter62903052007-05-18 23:11:24 +00007044- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007045 "except E as target:". This is to provide forwards compatibility
7046 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007047
Brett Cannon229cee22007-05-05 01:34:02 +00007048- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007053- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007054 setting a plain string, ie don't expand to single letter identifiers.
7055
Raymond Hettinger13936692007-04-11 18:40:58 +00007056- Request #1191699: Slices can now be pickled.
7057
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007058- Request #1193128: str.translate() now allows a None argument for
7059 translations that only remove characters without re-mapping the
7060 remaining characters.
7061
Georg Brandl5cb76c12007-03-21 09:00:39 +00007062- Patch #1682205: a TypeError while unpacking an iterable is no longer

7064
Neal Norwitzaa754b72007-03-21 06:39:48 +00007065- Remove unused file Python/fmod.c.
7066
Guido van Rossum143b5642007-03-23 04:58:42 +00007067- Bug #1683368: The object.__init__() and object.__new__() methods are
7068 now stricter in rejecting excess arguments. The only time when
7069 either allows excess arguments is when it is not overridden and the
7070 other one is. For backwards compatibility, when both are
7071 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007072 warning later). Also, type.__init__() insists on the same signature
7073 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007074
Georg Brandl3ee81df2008-05-17 18:14:43 +00007075- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7076 object to complex using its __complex__() method before falling back
7077 to the __float__() method. Therefore, the functions in the cmath
7078 module now can operate on objects that define a __complex__()
7079 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007097- Bug #1678647: write a newline after printing an exception in any
7098 case, even when converting the value to a string failed.
7099
Georg Brandl871f1bc2007-03-12 13:17:36 +00007100- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007101 its argument, if it exists. If not, it will work like before. This
7102 allows customizing the output of dir() in the presence of a
7103 __getattr__().

7112 parthensized forms. This means complex(repr(x)) now works instead of
7113 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007114
Georg Brandlaa2321b2007-03-07 00:40:28 +00007115- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007116 makes the filenames the warning module prints much more sensible
7117 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007130- Patch #1674228: when assigning a slice (old-style), check for the
7131 sq_ass_slice instead of the sq_slice slot.
7132
Georg Brandl3ee81df2008-05-17 18:14:43 +00007133- When printing an unraisable error, don't print exceptions. before

7744 Python would crash instead of raising an error.
7745

7762 incompatibility since it never made sense with ordinary subclasses
7763 -- the failure just occurred later, with a more cumbersome
7764 exception.

8048 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008049
Georg Brandl3ee81df2008-05-17 18:14:43 +00008050- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008051 that the SMTP.starttls() caller no longer needs to call ehlo()
8052 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008053 does not claim to support starttls. Adds the
8054 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008153 time so that opening a database previously created with the DB_DUP
8154 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8155 opens. Specifically: dictionary assignment to a DB object will
8156 replace all values for a given key when the database allows
8157 duplicate values. DB users should use DB.put(k, v) when they want
8158 to store duplicates; not DB[k] = v.

8165 characters with ASCII value less than 32. Also, it correctly quotes
8166 dots only if they occur on a single line, as opposed to the previous
8167 behavior of quoting dots if they are the second character of any
8168 line.

8491-----
8492
Georg Brandl3ee81df2008-05-17 18:14:43 +00008493- Unified naming convention for free lists and their limits. All free
8494 lists in Object/ are named ``free_list``, the counter ``numfree``
8495 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8496 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008497
Georg Brandl3ee81df2008-05-17 18:14:43 +00008498- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8499 to ``PyTuple_SetItem``, it can be used to populate a brand new
8500 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008501
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008502- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008504- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
8505 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8506 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008507
8508- Patch #1720595: add T_BOOL to the range of structmember types.
8509
8510- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8511 ``PyFloat_GetInfo()`` to the float API.
8512
Georg Brandl3ee81df2008-05-17 18:14:43 +00008513- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8514 of w# format code incorrectly truncated the length to an int, even
8515 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8516 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008517
Georg Brandl3ee81df2008-05-17 18:14:43 +00008518- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8519 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008520
Georg Brandl3ee81df2008-05-17 18:14:43 +00008521- PEP 3123: Provide forward compatibility with Python 3.0, while
8522 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8523 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008524
Georg Brandl3ee81df2008-05-17 18:14:43 +00008525- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8526 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008527
8528- Patch #1733960: Allow T_LONGLONG to accept ints.
8529
8530- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
8531
Christian Heimes000a0742008-01-03 22:16:32 +00008532- Added a new API function ``PyImport_ImportModuleNoBlock``.

8535
8536- Fix some leftovers from the conversion from int to Py_ssize_t
8537 (relevant to strings and sequences of more than 2**31 items).
8538
8539- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8540 outside of pystate.c and should not be necessary.
8541
Georg Brandl3ee81df2008-05-17 18:14:43 +00008542- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8543 absolute imports. In earlier versions they might have used relative
8544 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008545
Georg Brandl3ee81df2008-05-17 18:14:43 +00008546- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8547 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008548
Georg Brandl3ee81df2008-05-17 18:14:43 +00008549- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8550 macro so it can be used as an expression.

8555
Georg Brandl3ee81df2008-05-17 18:14:43 +00008556- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8557 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8558 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8559 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008560
Georg Brandl3ee81df2008-05-17 18:14:43 +00008561- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00008574- Removed the macfs module. It had been deprecated since Python 2.5.
8575 This lead to the deprecation of macostools.touched() as it relied
8576 solely on macfs and was a no-op under OS X.
