682 int.__pow__. These overflow checks were causing int.__pow__ to produce
683 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100684 compiler optimizing the check away. Also fix similar overflow checks
685 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +0100761- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
762 Distutils-based packages with C extension modules may fail because
763 Apple has removed gcc-4.2, the version used to build python.org
764 64-bit/32-bit Pythons. If the user does not explicitly override
765 the default C compiler by setting the CC environment variable,
766 Distutils will now attempt to compile extension modules with clang
767 if gcc-4.2 is required but not found. Also as a convenience, if
768 the user does explicitly set CC, substitute its value as the default
769 compiler in the Distutils LDSHARED configuration variable for OS X.
770 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
771 SDK, neither of which are available in Xcode 4. This change does not
772 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001045- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1046 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1047 interpreter process. This could cause failures in non-Distutils subprocesses
1048 and was unreliable since tests or user programs could modify the interpreter
1049 environment after Distutils set it. Instead, have Distutils set the the
1050 deployment target only in the environment of each build subprocess. It is
1051 still possible to globally override the default by setting
1052 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1053 greater or equal to the default value, the value with which the interpreter
1054 was built.

1083 updating the check interval, so if the user decreases the check interval,
1084 the ticker doesn't have to wind down to zero from the old starting point
1085 before the new interval takes effect. And if the user increases the
1086 interval, it makes sure the new limit takes effect right away rather have an
1087 early task switch before recognizing the new interval.

Raymond Hettinger74f869e2010-09-13 22:14:36 +00002030- Issue #9826: OrderedDict.__repr__ can now handle self-referential
2031 values: d['x'] = d.
2032
Victor Stinner8fc843b2010-09-17 23:35:50 +00002033- Issue #767645: Set os.path.supports_unicode_filenames to True on Mac OS X.
Victor Stinner46287f52010-09-13 20:31:34 +00002034
Antoine Pitroue4195e82010-09-12 14:56:27 +00002035- Issue #9837: The read() method of ZipExtFile objects (as returned by
2036 ZipFile.open()) could return more bytes than requested.
2037
Raymond Hettinger20397532010-09-12 02:11:45 +00002038- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2039 This prevents user-created self-referencing ordered dictionaries from
2040 becoming permanently uncollectable GC garbage. The downside is that
2041 removing __del__ means that the internal doubly-linked list has to wait for
2042 GC collection rather than freeing memory immediately when the refcnt drops
2043 to zero.
2044
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002045- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00002046 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002047 value.
2048
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002049- Issue #9792: In case of connection failure, socket.create_connection()
2050 would swallow the exception and raise a new one, making it impossible
2051 to fetch the original errno, or to filter timeout errors. Now the
2052 original error is re-raised.
2053
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002054- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
2055 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
2056 be updated back after the system call. Original patch by Brian Brazil.
2057
Antoine Pitroudca9de92010-09-04 17:52:26 +00002058- Issue #1100562: Fix deep-copying of objects derived from the list and

2060

2062 ConfigParser.write.
2063
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00002064- Issue #808164: Fixed socket.close to avoid references to globals, to
2065 avoid issues when socket.close is called from a __del__ method.
2066
Terry Reedyd2d2ae92010-11-11 23:22:19 +00002067- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
2068 can be set to False to turn off the previously undocumented 'popularity'
2069 heuristic. Patch by Terry Reedy and Eli Bendersky
2070
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00002071- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
2072 falling into recursion.
2073
R. David Murray7c4bf552010-08-25 01:45:57 +00002074- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2075 character years even if the message contains RFC822 two character years.
2076
Daniel Stutzbach91287322010-08-24 21:09:30 +00002077- Issue #8750: Fixed MutableSet's methods to correctly handle
2078 reflexive operations, namely x -= x and x ^= x.

2084 errors.
2085
Vinay Sajip1ddd51f2010-08-23 17:50:30 +00002086- Issue #9501: Fixed logging regressions in cleanup code.
2087
Raymond Hettinger917bba12010-08-22 08:01:58 +00002088- Issue #9214: Set operations on KeysView or ItemsView in the collections
2089 module now correctly return a set. (Patch by Eli Bendersky.)
2090
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002091- Issue #9617: Signals received during a low-level write operation aren't
2092 ignored by the buffered IO layer anymore.
2093
Benjamin Peterson52c36052010-08-21 03:03:22 +00002094- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
2095 are not held onto after they are deleted elsewhere.
2096
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002097- Issue #9626: the view methods for collections.OrderedDict() were returning
2098 the unordered versions inherited from dict. Those methods are now
2099 overridden to provide ordered views.
2100
Éric Araujo0389ae62010-08-14 03:07:46 +00002101- Issue #8688: MANIFEST files created by distutils now include a magic
2102 comment indicating they are generated. Manually maintained MANIFESTs
2103 without this marker will not be overwritten or removed.
2104
Antoine Pitroue1436d12010-08-12 15:25:51 +00002105- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2106 and a BadZipfile error is raised if it doesn't match (as used to be the
2107 case in Python 2.5 and earlier).
2108
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002109- Issue #9550: a BufferedReader could issue an additional read when the
2110 original read request had been satisfied, which could block indefinitely
2111 when the underlying raw IO channel was e.g. a socket. Report and original
2112 patch by Jason V. Miller.
2113
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002114- Issue #9551: Don't raise TypeError when setting the value to None for
2115 SafeConfigParser instances constructed with allow_no_value == True.
2116

2131
Senthil Kumarane677ecf2010-08-08 11:56:31 +00002132- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
2133 This is how it is supposed to work, wget and curl do the same. Previous
2134 behavior was wrong.
2135
Giampaolo Rodolà47617ab2010-08-04 08:35:25 +00002136- Issue #2944: asyncore doesn't handle connection refused correctly.

2142 the option character for the added 'h/help' option if prefix_chars
2143 does not contain a '-', instead of raising an error.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002502- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2503 start byte and the continuation byte(s) are now considered invalid, instead
2504 of the number of bytes specified by the start byte.
2505 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2506 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

2517 objects. (1) The comparison could incorrectly return True in some cases
2518 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

2715 operation raises multiple signals and more than one of those signals is
2716 trapped, the specification determines the order in which the signals should be

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002863 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2864 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

2886-----------------
2887
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002888- Issue #7301: Add environment variable $PYTHONWARNINGS.
2889
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002890- Issue #8329: Don't return the same lists from select.select when no fds are
2891 changed.
2892
Georg Brandlfee0f442010-05-22 21:26:21 +00002893- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002894 on 64-bit machines. The shift count for either left or right shift is
2895 permitted to be up to sys.maxsize.
2896
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002897- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002901- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2902
Georg Brandlfee0f442010-05-22 21:26:21 +00002903- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2904 with a non-empty format string. This is an effort to future-proof user
2905 code. If a derived class does not currently implement __format__ but later
2906 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002907 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002908 Python 3.3 and it will be an error in Python 3.4.

Victor Stinner66644262010-03-10 22:30:19 +00002923- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002924 (SIGINT). If an error occurs while importing the site module, the error is

Georg Brandlfee0f442010-05-22 21:26:21 +00002941- Issue #8257: The Decimal construct now accepts a float instance directly,
2942 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002943
2944 >>> Decimal(1.1)
2945 Decimal('1.100000000000000088817841970012523233890533447265625')
2946
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002947- collections.Counter() now supports a subtract() method.
2948
Georg Brandlfee0f442010-05-22 21:26:21 +00002949- The functools module now has a total_ordering() class decorator to simplify
2950 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002952- The functools module also adds cmp_to_key() as a tool to transition old-style
2953 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002954
Georg Brandlfee0f442010-05-22 21:26:21 +00002955- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2956 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002957
Georg Brandlfee0f442010-05-22 21:26:21 +00002958- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2959 InvalidOperation instead of returning False. (Comparisons involving a quiet
2960 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2961 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002962
Georg Brandlfee0f442010-05-22 21:26:21 +00002963- Issue #2531: Comparison operations between floats and Decimal instances now
2964 return a result based on the numeric values of the operands; previously they
2965 returned an arbitrary result based on the relative ordering of id(float) and
2966 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002967
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002968- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002969 argument `-` which tells it to read files to compile from stdin. Each line is
2970 read on demand and the named file is compiled immediately. (Original patch by
2971 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002976- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2977 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002978 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00002980- Comparisons using one of <, <=, >, >= between a complex instance and a
2981 Fractions instance now raise TypeError instead of returning True/False. This
2982 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2983 <=> complex, and complex <=> complex comparisons.

3091 inconsistent: __int__ was used for some integer codes but not for others, and
3092 the set of integer codes for which it was used differed between native packing
3093 and standard packing.)

3307 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
3308 Xicluna who helped with the patch.

3325 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00003326 library would return a bogus result; on Solaris, it was possible to crash the

3346 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3347 returning NULL. The macro now returns a statically allocated empty string
3348 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003401 file position when calling `truncate()`. It would previously change the file
3402 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003403 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3404

3406 class used to represent files stored inside an archive. The new
3407 implementation is significantly faster and can be wrapped in a
3408 ``io.BufferedReader`` object for more speedups. It also solves an issue
3409 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3410 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003420- Issue #7748: Since unicode values are supported for some metadata options in
3421 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3422 encoded string for them. This ensures that the upload and register commands
3423 send the correct values to PyPI without any error.

3535
Georg Brandlba83f822010-03-14 09:50:54 +00003536 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00003694- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3695 decimal string that's guaranteed to round back to x under correct rounding
3696 (with round-half-to-even rounding mode). Previously it gave a string based on
3697 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3698 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3699 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003700
Georg Brandlba83f822010-03-14 09:50:54 +00003701- Issue #7117: On almost all platforms: float-to-string and string-to-float
3702 conversions within Python are now correctly rounded. Places these conversions
3703 occur include: str for floats and complex numbers; the float and complex
3704 constructors; old-style and new-style numeric formatting; serialization and
3705 deserialization of floats and complex numbers using marshal, pickle and json;
3706 parsing of float and imaginary literals in Python code; Decimal-to-float
3707 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003708
Georg Brandlba83f822010-03-14 09:50:54 +00003709 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3710 providing correctly-rounded strtod and dtoa C functions. This code is
3711 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3712 the C compiler. There may be a small number of platforms on which correct
3713 operation of this code cannot be guaranteed, so the code is not used: notably,
3714 this applies to platforms where the C double format is not IEEE 754 binary64,
3715 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3716 and Python's configure script is unable to determine how to change the FPU
3717 precision. On these platforms conversions use the platform strtod and dtoa,
3718 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003720- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3721 uses the correctly-rounded string <-> float conversions described above (when
3722 available), and so produces correctly rounded results that will display nicely
3723 under the float repr. There are two related small changes: (1) round now
3724 accepts any class with an ``__index__()`` method for its second argument (but
3725 no longer accepts floats for the second argument), and (2) an excessively
3726 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3727 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003874- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3875 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3876 but with at least one decimal point and with a default precision
3877 of 12. Previously, the behavior the same but with a default precision of 6.
3878 This more closely matches ``str()``, and reduces surprises when adding
3879 alignment flags to the empty presentation type. This also affects the new
3880 complex.__format__ in the same way.
3881
3882- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4013 collecting the oldest generation) so that allocating lots of objects without
4014 destroying them does not show quadratic performance. Based on a proposal by

4019
Georg Brandlba83f822010-03-14 09:50:54 +00004020- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4021 existing .py counterpart, override the co_filename attributes of all code
4022 objects if the original filename is obsolete (which can happen if the file has
4023 been renamed, moved, or if it is accessed through different paths). Patch by
4024 Ziga Seilnacht and Jean-Paul Calderone.

Georg Brandl6425a2f2008-12-28 11:54:53 +00004043- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00004044 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.

Georg Brandlba83f822010-03-14 09:50:54 +00004063- Issue #4445: Replace ``sizeof(PyStringObject)`` with
4064 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
4065 instances. On a typical machine this saves 3 bytes of memory (on average) per
4066 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00004068- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

4070 instead of throwing a MemoryError.
4071
Georg Brandlba83f822010-03-14 09:50:54 +00004072- Issue #3689: The list reversed iterator now supports __length_hint__ instead

Benjamin Petersonc078f922008-11-21 22:27:24 +00004075- Issue #4367: Python would segfault during compiling when the unicodedata

4077
Georg Brandlba83f822010-03-14 09:50:54 +00004078- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4079 file objects with closefd=False. The file descriptor is still kept open but
4080 the file object behaves like a closed file. The ``FileIO`` object also got a
4081 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00004083- Issue #4348: Some bytearray methods returned that didn't cause any change to
4084 the bytearray, returned the same bytearray instead of a copy.
4085
Georg Brandlba83f822010-03-14 09:50:54 +00004086- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

4099 __future__ import didn't work.
4100
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004101- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00004102 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00004104- On windows, ``os.chdir()`` given unicode was not working if
4105 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4106 this code path is really executed because I cannot move to such directory on
4107 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00004108
Georg Brandlba83f822010-03-14 09:50:54 +00004109- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4110 element is temporarily replaced with an equivalent frozenset. But the
4111 eventual KeyError would always report the empty ``frozenset()`` as the missing
4112 key. Now it correctly refers to the initial element.

4130 returned them on 64bit platforms.
4131
Walter Dörwalded960ac2009-05-03 22:36:33 +00004132- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4133 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4134 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4135 of using the replace error handler in PyUnicode_DecodeUTF8().
4136
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004137- Issue #3739: The unicode-internal encoder now reports the number of characters
4138 consumed like any other encoder (instead of the number of bytes).
4139
Georg Brandlba83f822010-03-14 09:50:54 +00004140- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4141 allocator will be automatically disabled when running under Valgrind. This
4142 gives improved memory leak detection when running under Valgrind, while taking
4143 advantage of pymalloc at other times.

5374 __all__ attribute, rather than using a hardcoded and incomplete list.
5375
R. David Murray14dcd432009-10-14 13:58:07 +00005376- Issue #7058: Added save/restore for things like sys.argv and cwd to
5377 runtest_inner in regrtest, with warnings if the called test modifies them,
5378 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005385- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5386 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005387 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5388 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00005390- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
5391 regression tests in parallel, shortening the total runtime.
5392
Georg Brandlba83f822010-03-14 09:50:54 +00005393- Issue #5354: New test support function import_fresh_module() makes it easy to
5394 import both normal and optimised versions of modules. test_heapq and
5395 test_warnings have been adjusted to use it, tests for other modules with both
5396 C and Python implementations in the stdlib can be adjusted to use it over
5397 time.

5404
Georg Brandlba83f822010-03-14 09:50:54 +00005405- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5406 should cause a test to be skipped are now done using import_module from test
5407 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005508- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5509
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005510- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5511 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5512 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5513 ``printf`` function, whereas PyString_FromFormat has an independent
5514 implementation and uses "%zd" on all platforms for size_t values.
5515 This makes a difference on win64, where ``printf`` needs "%Id" to display
5516 64bit values.
5517
Benjamin Peterson97179b02008-09-09 20:55:01 +00005518- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5522 object; previously an int would be returned for small values. the __long__
5523 method is allowed to return either an int or a long, but the behaviour of
5524 float objects should not change to respect backward compatibility.
5525
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005526- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00005532 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005533 was correctly parsed but parsing of subsequent arguments failed.
5534
Vinay Sajip35e3b032008-09-01 14:33:59 +00005535- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005536 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5537 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5538 when given a tuple of classes as second argument, were looking up
5539 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5540 type object.
5541
Neal Norwitz18aa3882008-08-24 05:04:52 +00005542- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005679What's New in Python 2.6 beta 3?
5680================================
5681
Barry Warsaw07a4a382008-08-21 01:15:08 +00005682*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005683
5684Core and Builtins
5685-----------------
5686
Guido van Rossumf8402962008-08-20 15:01:50 +00005687- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5688 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5689 extensions do not automatically benefit from the class attribute
5690 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5691 to their tp_flags field if they care. This is a backwards
5692 compatibility feature; in 3.0, all types will use the cache by
5693 default.
5694
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005695- Keyword arguments can now follow starred arguments. (``f(a, *args,
5696 keyword=23)`` is now valid syntax.)
5697
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005698- ctypes function pointers that are COM methods have a boolean True
5699 value again.
5700
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005701- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5702 by denying s# to parse objects that have a releasebuffer procedure,
5703 and introducing s*.
5704
Georg Brandl1e13ea92008-08-11 09:07:59 +00005705- Issue #3537: Fix an assertion failure when an empty but presized dict
5706 object was stored in the freelist.
5707
Mark Dickinsonb6467572008-08-04 21:30:09 +00005708- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5709 ValueError consistently across platforms.
5710
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005711- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5712 (64bit Unix, for example), unichr() would truncate its argument and return
5713 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5714
Neal Norwitze7d8be82008-07-31 17:17:14 +00005715- Apply security patches from Apple.
5716
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005717- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5718 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5719
Antoine Pitrou92f82162008-07-25 22:22:08 +00005720- Issue #1819: function calls with several named parameters are now on
5721 average 35% faster (as measured by pybench).
5722
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005723- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5724 the python debugger steps into a class statement: the free variables (local
5725 variables defined in an outer scope) would be deleted from the outer scope.
5726
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005727- Issue #2620: Overflow checking when allocating or reallocating memory
5728 was not always being done properly in some python types and extension
5729 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5730 all been updated to perform better checks and places in the code that
5731 would previously leak memory on the error path when such an allocation
5732 failed have been fixed.

5735-------
5736
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005737- Issue #3612: Added some missing basic types in ctypes.wintypes.
5738
Benjamin Petersone977ad42008-08-20 01:42:01 +00005739- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5740 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5741
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005742- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5743 version reported by these tools does not necessarily follow the python
5744 version numbering scheme, so the module is less strict when parsing it.
5745
Nick Coghlanf70385a2008-08-18 12:42:46 +00005746- Issue #2235: Added Py3k warnings for types which will become unhashable
5747 under the stricter __hash__ inheritance rules in 3.0. Several types
5748 which did not meet the rules for hash invariants and were already
5749 unhashable in 3.0 have now been explicitly flagged as unhashable in
5750 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5751 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5752
Brett Cannon88f801d2008-08-18 00:46:22 +00005753- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5754 imported into the module but exposed as part of the module's API.
5755
Brett Cannon7b96f072008-08-18 00:41:11 +00005756- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5757
Brett Cannon46225e72008-08-18 00:36:52 +00005758- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5759
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005760- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5761
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005762- Issue #3575: Incremental decoder's decode function now takes bytearray
5763 by using 's*' instead of 't#'.
5764
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005765- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005766 fails unicode conversion on 2nd parameter. (windows only)
5767
Georg Brandl222e2082010-08-01 22:27:39 +00005768- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005769 in a redirect.
5770
Brett Cannonabe423e2008-08-16 21:47:07 +00005771- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005772 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005773
Facundo Batistaeb90b782008-08-16 14:44:07 +00005774- Issue #2776: fixed small issue when handling an URL with double slash
5775 after a 302 response in the case of not going through a proxy.
5776
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005777- Issue #2676: in the email package, content-type parsing was hanging on
5778 pathological input because of quadratic or exponential behaviour of a
5779 regular expression.
5780
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005781- Issue #3476: binary buffered reading through the new "io" library is now
5782 thread-safe.
5783
Brett Cannonbf3157b2008-08-14 05:00:03 +00005784- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5785 since mimetools itself is deprecated. Because modules are cached, all
5786 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5787
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005788- Issue #3134: shutil referenced undefined WindowsError symbol.
5789
Robert Schuppenies14646332008-08-10 11:01:53 +00005790- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5791 menu entries were not deleted.
5792
Brett Cannon83e81842008-08-09 23:30:55 +00005793- Copied the implementation of reduce() to _functools.reduce() to have a
5794 version that did not raise a DeprecationWarning under -3.
5795
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005796- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5797 a MemoryError rather than silently stop the iteration.
5798
Guido van Rossum59ce9012008-08-09 14:55:34 +00005799- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5800 to _sre.compile() will now be rejected. This should not affect anybody
5801 since the re.compile() function never generates invalid re-bytecode.
5802
Skip Montanaroa032bf42008-08-08 22:52:51 +00005803- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5804 upon first access it can be automatically initialized from the csv file if
5805 it wasn't initialized during instantiation.
5806
Brett Cannon3aa2a492008-08-06 22:28:09 +00005807- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5808 the reload() built-in has been removed.
5809
Brett Cannon7e30b672008-08-04 21:52:25 +00005810- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005811 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00005817
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005818- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5819 raised an AttributeError.
5820
Benjamin Peterson01a24322008-07-28 23:35:27 +00005821- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005822 asking for a specific length. This problem only affected files opened
5823 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005824
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005825- Issue #3449: Update decimal module to use most recent specification
5826 (v. 1.68) and tests (v. 2.58) from IBM.
5827
Georg Brandl222e2082010-08-01 22:27:39 +00005828- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005829

5832
Georg Brandlf9efabb2008-07-23 15:16:45 +00005833- Deprecate the "ast" parser function aliases.
5834
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005835- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5836
5837- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5838 invalid arguments.
5839
5840- Issue #3302: Fix several crashes when calling locale's gettext functions
5841 with None arguments.
5842
5843- Issue #3389: Allow resolving dotted names for handlers in logging
5844 configuration files.
5845
5846- Deprecate the sunaudio module for removal in Python 3.0.
5847
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005848- Issue #3394: zipfile.writestr sets external attributes when passed a
5849 file name rather than a ZipInfo instance, so files are extracted with
5850 mode 0600 rather than 000 under Unix.
5851
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005852- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5853 argument in python 2.5, this broke code that subclassed Popen to include its
5854 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005864- Issue #2235: the C API function PyObject_HashNotImplemented and its
5865 interaction with the tp_hash slot (added in 2.6b2) are now documented
5866
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005867- Issue #643841: The language reference now provides more detailed
5868 coverage of the lookup process for special methods. The disclaimers
5869 regarding lack of coverage of new-style classes have also been
5870 removed, since the coverage is now fairly reasonable.

5875
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005876*Release date: 17-Jul-2008*

5879-----------------
5880
Georg Brandl3e483f62008-07-16 22:57:41 +00005881- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5882 its methods now allow for items objects that can be converted to
5883 an integer using operator.index().
5884
Mark Dickinson64b7e502008-07-16 09:40:03 +00005885- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5886 produced a ValueError instead of giving the correct float.
5887
Eric Smitha5fa5a22008-07-16 00:11:49 +00005888- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5889 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5890
Mark Dickinson7103aa42008-07-15 19:08:33 +00005891- Issue #3008: the float type has a new instance method 'float.hex'
5892 and a new class method 'float.fromhex' to convert floating-point
5893 numbers to and from hexadecimal strings, respectively.
5894
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005895- Issue #2235: __hash__ is once again inherited by default. To allow
5896 collections.Hashable to remain meaningful in the presence of the
5897 default hash implementation (object.__hash__), it is now possible
5898 to explicit block inheritance of hash by setting __hash__=None at
5899 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5900 level.
5901
Nick Coghlanb028f502008-07-13 14:52:36 +00005902- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5903 the parent module cannot be found while performing an absolute import.
5904 This means that an incorrectly defined __package__ attribute will
5905 now only prevent relative imports in that module rather than causing
5906 all imports from that module to fail.
5907
Nick Coghlan14ff9942008-07-08 14:21:42 +00005908- Issue #2517: Allow unicode messages in Exceptions again by correctly
5909 bypassing the instance dictionary when looking up __unicode__ on
5910 new-style classes.
5911
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005912- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5913 set to a custom object whose write() method happens to install
5914 another file in sys.stdout.

5918 another thread's dictionary.
5919
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005920- Issue #3004: Minor change to slice.indices(): the start and stop
5921 arguments are now treated identically, making the behaviour easier
5922 to describe and understand. For example, slice(None, -10,
5923 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5924 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5925 10, -1).
5926
Georg Brandl278fc502008-07-19 12:46:12 +00005927- Issue #3219: Calling a function with repeated keyword arguments,
5928 f(a=2, a=23), would not cause a syntax error. This was a regression
5929 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00006379 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006380
6381 This is controlled by the configure argument ``--with-universal-archs``:
6382
6383 - ``--with-universal-archs=all``: install 4-way universal
6384
6385 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6386
6387 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6388
6389 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006441- Issue #1631171: Re-implement the 'warnings' module in C (the
6442 original Python code has been kept as backup). This will allow for
6443 using the 'warning's machinery in such places as the parser where
6444 use of pure Python code is not possible. Both the ``showarning()``
6445 and ``formatwarning()`` gain an optional 'line' argument which is
6446 not called by default for backwards-compatibility reasons. Setting
6447 ``warnings.showwarning()`` to an implementation that lacks support
6448 for the ``line`` argument will raise a DeprecationWarning.

6472
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006473- The getpass module has been improved on Unix. It now uses /dev/tty
6474 by default and uses stderr instead of stdout. A GetPassWarning is
6475 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006490- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006491 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006503- Issue #2385: distutils.core.run_script() makes __file__ available,
6504 so the controlled environment will more closely mirror the typical
6505 script environment. This supports setup.py scripts that refer to
6506 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006511- Issue #2550: The approach used by client/server code for obtaining
6512 ports to listen on in network-oriented tests has been refined in an
6513 effort to facilitate running multiple instances of the entire
6514 regression test suite in parallel without issue.
6515 test_support.bind_port() has been fixed such that it will always
6516 return a unique port -- which wasn't always the case with the
6517 previous implementation, especially if socket options had been set
6518 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6519 new implementation of bind_port() will actually raise an exception
6520 if it is passed an AF_INET/SOCK_STREAM socket with either the
6521 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6522 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6523 the socket it's been passed. This currently only applies to
6524 Windows. This option prevents any other sockets from binding to the
6525 host/port we've bound to, thus removing the possibility of the
6526 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6527 when a second SOCK_STREAM socket binds and accepts to a host/port
6528 that's already been bound by another socket. The optional preferred
6529 port parameter to bind_port() has been removed. Under no
6530 circumstances should tests be hard coding ports!
6531
6532 test_support.find_unused_port() has also been introduced, which will
6533 pass a temporary socket object to bind_port() in order to obtain an
6534 unused port. The temporary socket object is then closed and
6535 deleted, and the port is returned. This method should only be used
6536 for obtaining an unused port in order to pass to an external program
6537 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6538 a parameter to a server-oriented class that doesn't give you direct
6539 access to the underlying socket used.
6540
6541 Finally, test_support.HOST has been introduced, which should be used
6542 for the host argument of any relevant socket calls (i.e. bind and
6543 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006544
6545 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006546 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006547 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6548 test_asynchat and test_socket_ssl.
6549
Georg Brandl3ee81df2008-05-17 18:14:43 +00006550 It is now possible for multiple instances of the regression test
6551 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006830- Added the future_builtins module, which contains hex() and oct().
6831 These are the PEP 3127 version of these functions, designed to be
6832 compatible with the hex() and oct() builtins from Python 3.0. They
6833 differ slightly in their output formats from the existing, unchanged
6834 Python 2.6 builtins. The expected usage of the future_builtins
6835 module is:
6836 from future_builtins import hex, oct
6837
Eric Smith7ef40bf2008-02-20 23:34:22 +00006838- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6839 exponents for exponents with absolute value < 100. Follows C99
6840 standard. This is a change on Windows, which would use 3 digits.
6841 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6842 so that any alterations it does to the resulting string will be
6843 available in stringlib/formatter.h (for float.__format__).
6844
Eric Smith5a3c1352008-02-19 13:21:56 +00006845- Implemented PEP 3101, Advanced String Formatting. This adds a new
6846 builtin format(); a format() method for str and unicode; a
6847 __format__() method to object, str, unicode, int, long, float, and
6848 datetime; the class string.Formatter; and the C API
6849 PyObject_Format().
6850
Georg Brandl3ee81df2008-05-17 18:14:43 +00006851- Fixed several potential crashes, all caused by specially crafted
6852 __del__ methods exploiting objects in temporarily inconsistent
6853 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006854
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006855- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006856 prevent a possible crash: an Abstract Base Class would try to access
6857 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006858

Georg Brandl3ee81df2008-05-17 18:14:43 +00006862- Clear all free lists during a gc.collect() of the highest generation
6863 in order to allow pymalloc to free more arenas. Python may give back
6864 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006865
Georg Brandl3ee81df2008-05-17 18:14:43 +00006866- Issue #2045: Fix an infinite recursion triggered when printing a
6867 subclass of collections.defaultdict, if its default_factory is set
6868 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006869
Christian Heimesf75dbef2008-02-08 00:11:31 +00006870- Fixed a minor memory leak in dictobject.c. The content of the free
6871 list was not freed on interpreter shutdown.
6872
Georg Brandl21e99f42010-03-07 15:23:59 +00006873- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006874 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006875
Georg Brandl3ee81df2008-05-17 18:14:43 +00006876- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6877 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006878 to compact the internal free lists of pre-allocted ints and floats.
6879
Georg Brandl3ee81df2008-05-17 18:14:43 +00006880- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6881 calls. Python expected the return type int but the fork familie
6882 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006883
Georg Brandl3ee81df2008-05-17 18:14:43 +00006884- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006896- Patch #1473257: generator objects gain a gi_code attribute. This is
6897 the same object as the func_code attribute of the function that
6898 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006899
Georg Brandl3ee81df2008-05-17 18:14:43 +00006900- Issue #1920: "while 0" statements were completely removed by the
6901 compiler, even in the presence of an "else" clause, which is
6902 supposed to be run when the condition is false. Now the compiler
6903 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006904
Guido van Rossumeead05f2008-01-24 18:21:02 +00006905- A few crashers fixed: weakref_in_del.py (issue #1377858);
6906 loosing_dict_ref.py (issue #1303614, test67.py);
6907 borrowed_ref_[34].py (not in tracker).
6908
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006909- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006910 suppressed while an extension is loaded by calling SetErrorMode in
6911 dynload_win.c. The error is still reported properly.
6912
Georg Brandl3ee81df2008-05-17 18:14:43 +00006913- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006914 several extension methods and modules do not work without unicode
6915 support.
6916
Georg Brandl26543b12008-01-21 18:36:51 +00006917- Issue #1882: when compiling code from a string, encoding cookies in the
6918 second line of code were not always recognized correctly.
6919
Georg Brandl14404b62008-01-19 19:27:05 +00006920- Issue #1679: "0x" was taken as a valid integer literal.
6921
Georg Brandl6caad7d2008-01-26 14:19:22 +00006922- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006923 added.
6924
Christian Heimesc94e2b52008-01-14 04:13:37 +00006925- sys.float_info / PyFloat_GetInfo: The floating point information
6926 object was converted from a dict to a specialized structseq object.
6927
Georg Brandl3ee81df2008-05-17 18:14:43 +00006928- Patch #1816: Added sys.flags structseq. It exposes the status of
6929 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006930
Georg Brandl3ee81df2008-05-17 18:14:43 +00006931- Objects/structseq.c: Implemented new structseq representation. The
6932 patch makes structseqs (e.g. the return value of os.stat) more
6933 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006934
Georg Brandl3ee81df2008-05-17 18:14:43 +00006935- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006957 and INF. float("nan"), float("inf") and float("-inf") now work on
6958 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006959
Georg Brandl3ee81df2008-05-17 18:14:43 +00006960- Compiler now generates simpler and faster code for dictionary
6961 literals. The oparg for BUILD_MAP now indicates an estimated
6962 dictionary size. There is a new opcode, STORE_MAP, for adding
6963 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00007007- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007008 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7009 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007010
Georg Brandl3ee81df2008-05-17 18:14:43 +00007011- Issue #1686386: Tuple's tp_repr did not take into account the
7012 possibility of having a self-referential tuple, which is possible
7013 from C code. Nor did object's tp_str consider that a type's tp_str
7014 could do something that could lead to an inifinite recursion.
7015 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7016 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007017
Georg Brandl3ee81df2008-05-17 18:14:43 +00007018- Issue #1164: It was possible to trigger deadlock when using the
7019 'print' statement to write to a file since the GIL was not released
7020 as needed. Now PyObject_Print() does the right thing along with
7021 various tp_print implementations of the built-in types and those in
7022 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007023
Georg Brandl3ee81df2008-05-17 18:14:43 +00007024- Issue #1147: Exceptions were directly allowing string exceptions in
7025 their throw() method even though string exceptions no longer
7026 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007027
Georg Brandl3ee81df2008-05-17 18:14:43 +00007028- Issue #1096: Prevent a segfault from getting the repr of a very
7029 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007030
Brett Cannon1e534b52007-09-07 04:18:30 +00007031- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007032 PyObject_Call() never calling back out to Python code to trigger
7033 recursion depth updates/checks. Required the creation of a static
7034 RuntimeError instance in case normalizing an exception put the
7035 recursion check value past its limit. Fixes crashers
7036 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007037

Neal Norwitz0ac60192007-05-27 04:08:54 +00007051- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007052 __*__ attributes. (Some already existed, e.g., __doc__ and
7053 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007054
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007055- Add -3 option to the interpreter to warn about features that are
7056 deprecated and will be changed/removed in Python 3.0.
7057
Georg Brandl2134e752007-05-21 20:34:16 +00007058- Patch #1686487: you can now pass any mapping after '**' in function
7059 calls.
7060
Collin Winter62903052007-05-18 23:11:24 +00007061- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007062 "except E as target:". This is to provide forwards compatibility
7063 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007070- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007071 setting a plain string, ie don't expand to single letter identifiers.
7072
Raymond Hettinger13936692007-04-11 18:40:58 +00007073- Request #1191699: Slices can now be pickled.
7074
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007075- Request #1193128: str.translate() now allows a None argument for
7076 translations that only remove characters without re-mapping the
7077 remaining characters.
7078
Georg Brandl5cb76c12007-03-21 09:00:39 +00007079- Patch #1682205: a TypeError while unpacking an iterable is no longer

7083
Guido van Rossum143b5642007-03-23 04:58:42 +00007084- Bug #1683368: The object.__init__() and object.__new__() methods are
7085 now stricter in rejecting excess arguments. The only time when
7086 either allows excess arguments is when it is not overridden and the
7087 other one is. For backwards compatibility, when both are
7088 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007089 warning later). Also, type.__init__() insists on the same signature
7090 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007091
Georg Brandl3ee81df2008-05-17 18:14:43 +00007092- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7093 object to complex using its __complex__() method before falling back
7094 to the __float__() method. Therefore, the functions in the cmath
7095 module now can operate on objects that define a __complex__()
7096 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007097
Georg Brandl3ee81df2008-05-17 18:14:43 +00007098- Patch #1623563: allow __class__ assignment for classes with

7107 its type.

7113
Georg Brandl7b9c5552007-03-12 14:30:05 +00007114- Bug #1678647: write a newline after printing an exception in any
7115 case, even when converting the value to a string failed.
7116
Georg Brandl871f1bc2007-03-12 13:17:36 +00007117- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007118 its argument, if it exists. If not, it will work like before. This
7119 allows customizing the output of dir() in the presence of a
7120 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007128- Patch #1491866: change the complex() constructor to allow
7129 parthensized forms. This means complex(repr(x)) now works instead of
7130 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007131
Georg Brandlaa2321b2007-03-07 00:40:28 +00007132- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007133 makes the filenames the warning module prints much more sensible
7134 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007135

Georg Brandl0fca97a2007-03-05 22:28:08 +00007147- Patch #1674228: when assigning a slice (old-style), check for the
7148 sq_ass_slice instead of the sq_slice slot.
7149
Georg Brandl3ee81df2008-05-17 18:14:43 +00007150- When printing an unraisable error, don't print exceptions. before
7151 the name. This duplicates the behavior whening normally printing
7152 exceptions.

7781 exception.

7994 partial fix for Bug #1574584.
7995
Georg Brandl3ee81df2008-05-17 18:14:43 +00007996- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008062- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8063 with RFC 3207 and forgets any knowledge obtained from the server not
8064 obtained from the TLS negotiation itself. Patch contributed by Bill
8065 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008066
Georg Brandl3ee81df2008-05-17 18:14:43 +00008067- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008068 that the SMTP.starttls() caller no longer needs to call ehlo()
8069 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008070 does not claim to support starttls. Adds the
8071 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008126- itertools.chain() now has an alternate constructor,

8152 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8153 silently miscode subclasses of those types. Now, it raises a
8154 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008155

Georg Brandl3ee81df2008-05-17 18:14:43 +00008170 time so that opening a database previously created with the DB_DUP
8171 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8172 opens. Specifically: dictionary assignment to a DB object will
8173 replace all values for a given key when the database allows
8174 duplicate values. DB users should use DB.put(k, v) when they want
8175 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008176

8182 characters with ASCII value less than 32. Also, it correctly quotes
8183 dots only if they occur on a single line, as opposed to the previous
8184 behavior of quoting dots if they are the second character of any
8185 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008186

8508-----
8509
Georg Brandl3ee81df2008-05-17 18:14:43 +00008510- Unified naming convention for free lists and their limits. All free
8511 lists in Object/ are named ``free_list``, the counter ``numfree``
8512 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8513 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008514
Georg Brandl3ee81df2008-05-17 18:14:43 +00008515- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8516 to ``PyTuple_SetItem``, it can be used to populate a brand new
8517 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008518
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008519- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

8522 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8523 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008524
8525- Patch #1720595: add T_BOOL to the range of structmember types.
8526
8527- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8528 ``PyFloat_GetInfo()`` to the float API.
8529
Georg Brandl3ee81df2008-05-17 18:14:43 +00008530- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8531 of w# format code incorrectly truncated the length to an int, even
8532 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8533 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008534
Georg Brandl3ee81df2008-05-17 18:14:43 +00008535- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8536 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008538- PEP 3123: Provide forward compatibility with Python 3.0, while
8539 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8540 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008541
Georg Brandl3ee81df2008-05-17 18:14:43 +00008542- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8543 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008544
8545- Patch #1733960: Allow T_LONGLONG to accept ints.

8552
8553- Fix some leftovers from the conversion from int to Py_ssize_t
8554 (relevant to strings and sequences of more than 2**31 items).
8555
8556- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8557 outside of pystate.c and should not be necessary.
8558
Georg Brandl3ee81df2008-05-17 18:14:43 +00008559- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8560 absolute imports. In earlier versions they might have used relative
8561 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008562
Georg Brandl3ee81df2008-05-17 18:14:43 +00008563- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8564 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008565
Georg Brandl3ee81df2008-05-17 18:14:43 +00008566- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8567 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008573- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8574 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8575 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8576 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008577

Georg Brandl3ee81df2008-05-17 18:14:43 +00008591- Removed the macfs module. It had been deprecated since Python 2.5.
8592 This lead to the deprecation of macostools.touched() as it relied
8593 solely on macfs and was a no-op under OS X.
