16
Mark Dickinsona8d26682010-05-04 16:18:25 +000017- Issue #1533: fix inconsistency in range function argument
18 processing: any non-float non-integer argument is now converted to
19 an integer (if possible) using its __int__ method. Previously, only
20 small arguments were treated this way; larger arguments (those whose
21 __int__ was outside the range of a C long) would produce a TypeError.
22
Nick Coghlanc5e44852010-04-28 14:51:08 +000023- Issue #8202: sys.argv[0] is now set to '-m' instead of '-c' when
24 searching for the module file to be executed with the -m command
25 line option

Giampaolo Rodolàf7454fa2010-05-06 17:57:06 +000044- Issue #8573: asyncore _strerror() function might throw ValueError.
45
46- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
47 error messages when accessing undefined class attributes because of the cheap
48 inheritance with the underlying socket object.

61
Mark Dickinson4f96f5f2010-05-04 14:25:50 +000062- Issue #8567: Fix precedence of signals in Decimal module: when a
63 Decimal operation raises multiple signals and more than one of those
64 signals is trapped, the specification determines the order in which
65 the signals should be handled. In many cases this order wasn't
66 being followed, leading to the wrong Python exception being raised.
67
Antoine Pitrouf7fd8e42010-05-03 16:25:33 +000068- Issue #7865: The close() method of :mod:`io` objects should not swallow

113
Antoine Pitroufc69af12010-04-24 20:04:58 +0000114- Issue #5103: SSL handshake would ignore the socket timeout and block

116
Antoine Pitrou4d3e3722010-04-24 19:57:01 +0000117- The do_handshake() method of SSL objects now adjusts the blocking mode of
118 the SSL structure if necessary (as other methods already do).
119
Georg Brandl4341e542010-04-24 09:08:10 +0000120- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
121
Antoine Pitroub558f172010-04-23 23:25:45 +0000122- Issue #5238: Calling makefile() on an SSL object would prevent the

124
Antoine Pitroudfb299b2010-04-23 22:54:59 +0000125- Issue #7943: Fix circular reference created when instantiating an SSL
126 socket. Initial patch by Péter Szabó.
127
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000128- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
129 the string "python" as the *ident*. openlog() arguments are all optional
130 and keywords.
131
Antoine Pitroua5c4b552010-04-22 23:33:02 +0000132- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
133 a non-infinite timeout. Also make that method friendlier with applications
134 wanting to continue using the socket in clear-text mode, by disabling

136
Antoine Pitrouc715a9e2010-04-21 19:28:03 +0000137- Issue #8484: Load all ciphers and digest algorithms when initializing
138 the _ssl extension, such that verification of some SSL certificates
139 doesn't fail because of an "unknown algorithm".
140

163 filename and date, conforming to the 'standards' they were originally
164 designed to follow. This improves compatibility with patch tools.
165
R. David Murray27ef9372010-04-12 14:26:06 +0000166- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022

202 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
203 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
204 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)
205

226
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000227- Issue #8329: Don't return the same lists from select.select when no fds are
228 changed.
229
Mark Dickinson82791672010-04-06 16:47:55 +0000230- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
231 on 64-bit machines. The shift count for either left or right shift is

241 is called with a non-empty format string. This is an effort to
242 future-proof user code. If a derived class does not currently
243 implement __format__ but later adds its own __format__, it would
244 most likely break user code that had supplied a format string. This
245 will be changed to a DeprecationWaring in Python 3.3 and it will be
246 an error in Python 3.4.

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000273- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
274 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
275 and `ssl.OPENSSL_VERSION_NUMBER`.
276

286
Raymond Hettingera551f312010-04-04 18:34:45 +0000287- the functools module now has a total_ordering() class decorator
Georg Brandl4fabac52010-04-14 08:53:38 +0000288 to simplify the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000289
Raymond Hettingerbb006cf2010-04-04 21:45:01 +0000290- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +0000291 old-style comparison functions to new-style key-functions.

297 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000298 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs

Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000306- Issue #8233: When run as a script, py_compile.py optionally takes a single
307 argument `-` which tells it to read files to compile from stdin. Each line
308 is read on demand and the named file is compiled immediately. (Original
309 patch by Piotr Ożarowski).

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000421- Issue #8300: When passing a non-integer argument to struct.pack with any
422 integer format code, struct.pack first attempts to convert the non-integer
423 using its __index__ method. If that method is non-existent or raises
424 TypeError it goes on to try the __int__ method, as described below.
425
Georg Brandlba83f822010-03-14 09:50:54 +0000426- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
427 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
428 argument's __int__ method to convert to an integer before packing. It also
429 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
430 was inconsistent: __int__ was used for some integer codes but not for others,
431 and the set of integer codes for which it was used differed between native
432 packing and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000729- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000730 file position when calling `truncate()`. It would previously change the file
731 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000732 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000751- Issue #7748: Since unicode values are supported for some metadata options in
752 Distutils, the DistributionMetadata get_* methods will now return an utf-8
753 encoded string for them. This ensures that the upload and register commands
754 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000823What's New in Python 2.7 alpha 2?
824=================================

828Core and Builtins
829-----------------
830
Georg Brandlba83f822010-03-14 09:50:54 +0000831- The ``__complex__()`` method is now looked up on the class of instances to
832 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000833
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000834- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
835 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
836
Mark Dickinson1b34d252010-01-01 17:27:30 +0000837- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000838 DeprecationWarning when passed a float argument where an integer was expected.
839 These functions and methods now raise TypeError instead. The majority of the
840 effects of this change are in the extension modules, but some core functions
841 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
842 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +0000843

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000852- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
853 used to drop the time part of the result.
854
Georg Brandlba83f822010-03-14 09:50:54 +0000855- Issue #1811: Improve accuracy and cross-platform consistency for true division
856 of integers: the result of a/b is now correctly rounded for ints a and b (at
857 least on IEEE 754 platforms), and in particular does not depend on the
858 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000859
Georg Brandlba83f822010-03-14 09:50:54 +0000860- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
861 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
862 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +0000863
Georg Brandlba83f822010-03-14 09:50:54 +0000864- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +0000865 executables on OSX.
866
Georg Brandlba83f822010-03-14 09:50:54 +0000867 These executables now work properly with the arch(1) command: ``arch -ppc
868 python`` will start a universal binary version of python in PPC mode (unlike
869 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000870
Georg Brandlba83f822010-03-14 09:50:54 +0000871- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
872 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +0000873

Georg Brandlba83f822010-03-14 09:50:54 +0000883- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
884 allowing for a maximum number of tasks within the pool to be completed by the
885 worker before that worker is terminated, and a new one created to replace it.
Jesse Noller654ade32010-01-27 03:05:57 +0000886

Georg Brandlba83f822010-03-14 09:50:54 +0000892 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
893 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +0000913 Initial patch by Brian Curtin.
914
Georg Brandlba83f822010-03-14 09:50:54 +0000915- Distutils now correctly identifies the build architecture as "x86_64" when
916 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +0000917

923 long passwords. Initial patch by JP St. Pierre.
Tarek Ziadé2421d562009-12-20 23:23:34 +0000924
Georg Brandlba83f822010-03-14 09:50:54 +0000925- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000928- Issue #7349: Make methods of file objects in the io module accept None as an
929 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
930 the same as passing no argument.
931
Georg Brandlba83f822010-03-14 09:50:54 +0000932- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

952 to ``PyLong_AsLongAndOverflow()``.
Mark Dickinsona36507c2010-01-30 10:08:33 +0000953
Georg Brandlba83f822010-03-14 09:50:54 +0000954- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
955 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
956 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
957 float arguments for integer format codes (other than 'L'): previously an
958 attempt to pass a float resulted in a DeprecationWarning; now it gives a
959 TypeError. For the 'L' format code (which previously had no warning) there is
960 now a DeprecationWarning.

1005 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001006
Georg Brandlba83f822010-03-14 09:50:54 +00001007- Issue #3382: 'F' formatting for float and complex now convert the result to
1008 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1009 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001010
Georg Brandlba83f822010-03-14 09:50:54 +00001011- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1012 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001013
Georg Brandlba83f822010-03-14 09:50:54 +00001014- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1015 1e-100 used to raise OverflowError, but now gives the requested 120
1016 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001024
Georg Brandlba83f822010-03-14 09:50:54 +00001025- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1026 decimal string that's guaranteed to round back to x under correct rounding
1027 (with round-half-to-even rounding mode). Previously it gave a string based on
1028 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1029 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1030 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001031
Georg Brandlba83f822010-03-14 09:50:54 +00001032- Issue #7117: On almost all platforms: float-to-string and string-to-float
1033 conversions within Python are now correctly rounded. Places these conversions
1034 occur include: str for floats and complex numbers; the float and complex
1035 constructors; old-style and new-style numeric formatting; serialization and
1036 deserialization of floats and complex numbers using marshal, pickle and json;
1037 parsing of float and imaginary literals in Python code; Decimal-to-float
1038 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001039
Georg Brandlba83f822010-03-14 09:50:54 +00001040 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1041 providing correctly-rounded strtod and dtoa C functions. This code is
1042 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1043 the C compiler. There may be a small number of platforms on which correct
1044 operation of this code cannot be guaranteed, so the code is not used: notably,
1045 this applies to platforms where the C double format is not IEEE 754 binary64,
1046 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1047 and Python's configure script is unable to determine how to change the FPU
1048 precision. On these platforms conversions use the platform strtod and dtoa,
1049 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001050
Georg Brandlba83f822010-03-14 09:50:54 +00001051- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1052 uses the correctly-rounded string <-> float conversions described above (when
1053 available), and so produces correctly rounded results that will display nicely
1054 under the float repr. There are two related small changes: (1) round now
1055 accepts any class with an ``__index__()`` method for its second argument (but
1056 no longer accepts floats for the second argument), and (2) an excessively
1057 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1058 raises an exception.

1285 internal representation of integers, for performance reasons. Base 2**30 is
1286 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00001351- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1352 existing .py counterpart, override the co_filename attributes of all code
1353 objects if the original filename is obsolete (which can happen if the file has

1408
Georg Brandlba83f822010-03-14 09:50:54 +00001409- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1410 file objects with closefd=False. The file descriptor is still kept open but
1411 the file object behaves like a closed file. The ``FileIO`` object also got a
1412 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001432- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001435- On windows, ``os.chdir()`` given unicode was not working if
1436 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1437 this code path is really executed because I cannot move to such directory on
1438 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001440- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1441 element is temporarily replaced with an equivalent frozenset. But the
1442 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00001463- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1464 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1465 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1466 of using the replace error handler in PyUnicode_DecodeUTF8().
1467
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001468- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00001471- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2840
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002841- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2842 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2843 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2844 ``printf`` function, whereas PyString_FromFormat has an independent
2845 implementation and uses "%zd" on all platforms for size_t values.
2846 This makes a difference on win64, where ``printf`` needs "%Id" to display
2847 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00002867 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2868 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2869 when given a tuple of classes as second argument, were looking up
2870 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2871 type object.

2942 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2943 for catch_warnings() also led to an improvement in the raising of a
2944 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003010What's New in Python 2.6 beta 3?
3011================================
3012
Barry Warsaw07a4a382008-08-21 01:15:08 +00003013*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003014
3015Core and Builtins
3016-----------------
3017
Guido van Rossumf8402962008-08-20 15:01:50 +00003018- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3019 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3020 extensions do not automatically benefit from the class attribute
3021 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3022 to their tp_flags field if they care. This is a backwards
3023 compatibility feature; in 3.0, all types will use the cache by
3024 default.
3025
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003026- Keyword arguments can now follow starred arguments. (``f(a, *args,
3027 keyword=23)`` is now valid syntax.)
3028
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003029- ctypes function pointers that are COM methods have a boolean True
3030 value again.
3031
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003032- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3033 by denying s# to parse objects that have a releasebuffer procedure,
3034 and introducing s*.
3035
Georg Brandl1e13ea92008-08-11 09:07:59 +00003036- Issue #3537: Fix an assertion failure when an empty but presized dict
3037 object was stored in the freelist.
3038
Mark Dickinsonb6467572008-08-04 21:30:09 +00003039- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3040 ValueError consistently across platforms.
3041
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003042- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3043 (64bit Unix, for example), unichr() would truncate its argument and return
3044 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3045
Neal Norwitze7d8be82008-07-31 17:17:14 +00003046- Apply security patches from Apple.
3047
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003048- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3049 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3050
Antoine Pitrou92f82162008-07-25 22:22:08 +00003051- Issue #1819: function calls with several named parameters are now on
3052 average 35% faster (as measured by pybench).
3053
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003054- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3055 the python debugger steps into a class statement: the free variables (local
3056 variables defined in an outer scope) would be deleted from the outer scope.
3057
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003058- Issue #2620: Overflow checking when allocating or reallocating memory
3059 was not always being done properly in some python types and extension
3060 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3061 all been updated to perform better checks and places in the code that
3062 would previously leak memory on the error path when such an allocation
3063 failed have been fixed.
3064
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003065Library
3066-------
3067
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003068- Issue #3612: Added some missing basic types in ctypes.wintypes.
3069
Benjamin Petersone977ad42008-08-20 01:42:01 +00003070- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3071 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3072
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003073- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3074 version reported by these tools does not necessarily follow the python
3075 version numbering scheme, so the module is less strict when parsing it.
3076
Nick Coghlanf70385a2008-08-18 12:42:46 +00003077- Issue #2235: Added Py3k warnings for types which will become unhashable
3078 under the stricter __hash__ inheritance rules in 3.0. Several types
3079 which did not meet the rules for hash invariants and were already
3080 unhashable in 3.0 have now been explicitly flagged as unhashable in
3081 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3082 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3083
Brett Cannon88f801d2008-08-18 00:46:22 +00003084- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

3088
Brett Cannon46225e72008-08-18 00:36:52 +00003089- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3092
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003093- Issue #3575: Incremental decoder's decode function now takes bytearray
3094 by using 's*' instead of 't#'.
3095
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003096- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003097 fails unicode conversion on 2nd parameter. (windows only)
3098
Facundo Batista94f243a2008-08-17 03:38:39 +00003099- Issue 2464. urllib2 now supports a malformation in the URL received
3100 in a redirect.
3101
Brett Cannonabe423e2008-08-16 21:47:07 +00003102- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003103 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003104
Facundo Batistaeb90b782008-08-16 14:44:07 +00003105- Issue #2776: fixed small issue when handling an URL with double slash
3106 after a 302 response in the case of not going through a proxy.
3107
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003108- Issue #2676: in the email package, content-type parsing was hanging on
3109 pathological input because of quadratic or exponential behaviour of a
3110 regular expression.
3111
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003112- Issue #3476: binary buffered reading through the new "io" library is now
3113 thread-safe.
3114
Brett Cannonbf3157b2008-08-14 05:00:03 +00003115- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3116 since mimetools itself is deprecated. Because modules are cached, all
3117 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3118
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003119- Issue #3134: shutil referenced undefined WindowsError symbol.
3120
Robert Schuppenies14646332008-08-10 11:01:53 +00003121- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3122 menu entries were not deleted.
3123
Brett Cannon83e81842008-08-09 23:30:55 +00003124- Copied the implementation of reduce() to _functools.reduce() to have a
3125 version that did not raise a DeprecationWarning under -3.
3126
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003127- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3128 a MemoryError rather than silently stop the iteration.
3129
Guido van Rossum59ce9012008-08-09 14:55:34 +00003130- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3131 to _sre.compile() will now be rejected. This should not affect anybody
3132 since the re.compile() function never generates invalid re-bytecode.
3133
Skip Montanaroa032bf42008-08-08 22:52:51 +00003134- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00003138- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3139 the reload() built-in has been removed.
3140
Brett Cannon7e30b672008-08-04 21:52:25 +00003141- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003142 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003153 asking for a specific length. This problem only affected files opened
3154 using the new "io" module, not the built-in open() function.

3181 mode 0600 rather than 000 under Unix.
3182
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003183- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Mark Dickinson64b7e502008-07-16 09:40:03 +00003216- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3217 produced a ValueError instead of giving the correct float.
3218
Eric Smitha5fa5a22008-07-16 00:11:49 +00003219- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3220 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3221
Mark Dickinson7103aa42008-07-15 19:08:33 +00003222- Issue #3008: the float type has a new instance method 'float.hex'
3223 and a new class method 'float.fromhex' to convert floating-point
3224 numbers to and from hexadecimal strings, respectively.
3225
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003226- Issue #2235: __hash__ is once again inherited by default. To allow
3227 collections.Hashable to remain meaningful in the presence of the
3228 default hash implementation (object.__hash__), it is now possible
3229 to explicit block inheritance of hash by setting __hash__=None at
3230 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3231 level.
3232
Nick Coghlanb028f502008-07-13 14:52:36 +00003233- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3234 the parent module cannot be found while performing an absolute import.
3235 This means that an incorrectly defined __package__ attribute will
3236 now only prevent relative imports in that module rather than causing
3237 all imports from that module to fail.
3238
Nick Coghlan14ff9942008-07-08 14:21:42 +00003239- Issue #2517: Allow unicode messages in Exceptions again by correctly

3249 another thread's dictionary.
3250
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003251- Issue #3004: Minor change to slice.indices(): the start and stop
3252 arguments are now treated identically, making the behaviour easier
3253 to describe and understand. For example, slice(None, -10,
3254 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3255 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3256 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00003258- Issue #3219: Calling a function with repeated keyword arguments,
3259 f(a=2, a=23), would not cause a syntax error. This was a regression
3260 from 2.4 caused by the switch to the new compiler.

3299 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003300 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00003772- Issue #1631171: Re-implement the 'warnings' module in C (the
3773 original Python code has been kept as backup). This will allow for
3774 using the 'warning's machinery in such places as the parser where
3775 use of pure Python code is not possible. Both the ``showarning()``
3776 and ``formatwarning()`` gain an optional 'line' argument which is
3777 not called by default for backwards-compatibility reasons. Setting
3778 ``warnings.showwarning()`` to an implementation that lacks support
3779 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003842- Issue #2550: The approach used by client/server code for obtaining
3843 ports to listen on in network-oriented tests has been refined in an
3844 effort to facilitate running multiple instances of the entire
3845 regression test suite in parallel without issue.
3846 test_support.bind_port() has been fixed such that it will always
3847 return a unique port -- which wasn't always the case with the
3848 previous implementation, especially if socket options had been set
3849 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3850 new implementation of bind_port() will actually raise an exception
3851 if it is passed an AF_INET/SOCK_STREAM socket with either the
3852 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3853 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3854 the socket it's been passed. This currently only applies to
3855 Windows. This option prevents any other sockets from binding to the
3856 host/port we've bound to, thus removing the possibility of the
3857 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3858 when a second SOCK_STREAM socket binds and accepts to a host/port
3859 that's already been bound by another socket. The optional preferred
3860 port parameter to bind_port() has been removed. Under no
3861 circumstances should tests be hard coding ports!
3862
3863 test_support.find_unused_port() has also been introduced, which will
3864 pass a temporary socket object to bind_port() in order to obtain an
3865 unused port. The temporary socket object is then closed and
3866 deleted, and the port is returned. This method should only be used
3867 for obtaining an unused port in order to pass to an external program
3868 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3869 a parameter to a server-oriented class that doesn't give you direct
3870 access to the underlying socket used.
3871
3872 Finally, test_support.HOST has been introduced, which should be used
3873 for the host argument of any relevant socket calls (i.e. bind and
3874 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003875
3876 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003877 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003878 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3879 test_asynchat and test_socket_ssl.
3880
Georg Brandl3ee81df2008-05-17 18:14:43 +00003881 It is now possible for multiple instances of the regression test
3882 suite to run in parallel without issue.

4150
Fred Drakea8ee94b2008-03-01 02:45:07 +00004151- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004152 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00004157
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004158- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004159 issue 215555 for a discussion.
4160
Eric Smitha73fbe72008-02-23 03:09:44 +00004161- Added the future_builtins module, which contains hex() and oct().
4162 These are the PEP 3127 version of these functions, designed to be
4163 compatible with the hex() and oct() builtins from Python 3.0. They
4164 differ slightly in their output formats from the existing, unchanged
4165 Python 2.6 builtins. The expected usage of the future_builtins
4166 module is:
4167 from future_builtins import hex, oct
4168
Eric Smith7ef40bf2008-02-20 23:34:22 +00004169- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4170 exponents for exponents with absolute value < 100. Follows C99
4171 standard. This is a change on Windows, which would use 3 digits.
4172 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4173 so that any alterations it does to the resulting string will be
4174 available in stringlib/formatter.h (for float.__format__).
4175
Eric Smith5a3c1352008-02-19 13:21:56 +00004176- Implemented PEP 3101, Advanced String Formatting. This adds a new
4177 builtin format(); a format() method for str and unicode; a
4178 __format__() method to object, str, unicode, int, long, float, and
4179 datetime; the class string.Formatter; and the C API
4180 PyObject_Format().
4181
Georg Brandl3ee81df2008-05-17 18:14:43 +00004182- Fixed several potential crashes, all caused by specially crafted
4183 __del__ methods exploiting objects in temporarily inconsistent
4184 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004185
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004186- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187 prevent a possible crash: an Abstract Base Class would try to access
4188 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004189
Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Fixed repr() and str() of complex numbers with infinity or nan as
4191 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Clear all free lists during a gc.collect() of the highest generation
4194 in order to allow pymalloc to free more arenas. Python may give back
4195 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004196
Georg Brandl3ee81df2008-05-17 18:14:43 +00004197- Issue #2045: Fix an infinite recursion triggered when printing a
4198 subclass of collections.defaultdict, if its default_factory is set
4199 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004200
Christian Heimesf75dbef2008-02-08 00:11:31 +00004201- Fixed a minor memory leak in dictobject.c. The content of the free
4202 list was not freed on interpreter shutdown.
4203
Georg Brandl21e99f42010-03-07 15:23:59 +00004204- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004205 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004206
Georg Brandl3ee81df2008-05-17 18:14:43 +00004207- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4208 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004209 to compact the internal free lists of pre-allocted ints and floats.
4210
Georg Brandl3ee81df2008-05-17 18:14:43 +00004211- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4212 calls. Python expected the return type int but the fork familie
4213 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004214
Georg Brandl3ee81df2008-05-17 18:14:43 +00004215- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00004224- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4225 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004226
Georg Brandl3ee81df2008-05-17 18:14:43 +00004227- Patch #1473257: generator objects gain a gi_code attribute. This is
4228 the same object as the func_code attribute of the function that
4229 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004230
Georg Brandl3ee81df2008-05-17 18:14:43 +00004231- Issue #1920: "while 0" statements were completely removed by the
4232 compiler, even in the presence of an "else" clause, which is
4233 supposed to be run when the condition is false. Now the compiler
4234 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004235
Guido van Rossumeead05f2008-01-24 18:21:02 +00004236- A few crashers fixed: weakref_in_del.py (issue #1377858);
4237 loosing_dict_ref.py (issue #1303614, test67.py);
4238 borrowed_ref_[34].py (not in tracker).
4239
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004240- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004241 suppressed while an extension is loaded by calling SetErrorMode in
4242 dynload_win.c. The error is still reported properly.
4243
Georg Brandl3ee81df2008-05-17 18:14:43 +00004244- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004245 several extension methods and modules do not work without unicode
4246 support.
4247
Georg Brandl26543b12008-01-21 18:36:51 +00004248- Issue #1882: when compiling code from a string, encoding cookies in the
4249 second line of code were not always recognized correctly.
4250
Georg Brandl14404b62008-01-19 19:27:05 +00004251- Issue #1679: "0x" was taken as a valid integer literal.
4252
Georg Brandl6caad7d2008-01-26 14:19:22 +00004253- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004254 added.
4255
Christian Heimesc94e2b52008-01-14 04:13:37 +00004256- sys.float_info / PyFloat_GetInfo: The floating point information
4257 object was converted from a dict to a specialized structseq object.
4258
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259- Patch #1816: Added sys.flags structseq. It exposes the status of
4260 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004261
Georg Brandl3ee81df2008-05-17 18:14:43 +00004262- Objects/structseq.c: Implemented new structseq representation. The
4263 patch makes structseqs (e.g. the return value of os.stat) more
4264 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004265
Georg Brandl3ee81df2008-05-17 18:14:43 +00004266- Patch #1700288: added a type attribute cache that caches method
4267 accesses, resulting in speedups in heavily object-oriented code.

4275 envvar and sys.dont_write_bytecode attribute. All these can be set
4276 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004277
Georg Brandl3ee81df2008-05-17 18:14:43 +00004278- Improve some exception messages when Windows fails to load an
4279 extension module. Now we get for example '%1 is not a valid Win32
4280 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004281

Georg Brandl3ee81df2008-05-17 18:14:43 +00004288 and INF. float("nan"), float("inf") and float("-inf") now work on
4289 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004291- Compiler now generates simpler and faster code for dictionary
4292 literals. The oparg for BUILD_MAP now indicates an estimated
4293 dictionary size. There is a new opcode, STORE_MAP, for adding
4294 entries to the dictionary.

4325 interpreter. The directory/zipfile is automatically inserted as the
4326 first entry in sys.path.

4337
Georg Brandl21e99f42010-03-07 15:23:59 +00004338- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004339 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4340 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004341
Georg Brandl3ee81df2008-05-17 18:14:43 +00004342- Issue #1686386: Tuple's tp_repr did not take into account the
4343 possibility of having a self-referential tuple, which is possible
4344 from C code. Nor did object's tp_str consider that a type's tp_str
4345 could do something that could lead to an inifinite recursion.
4346 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4347 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004348
Georg Brandl3ee81df2008-05-17 18:14:43 +00004349- Issue #1164: It was possible to trigger deadlock when using the
4350 'print' statement to write to a file since the GIL was not released
4351 as needed. Now PyObject_Print() does the right thing along with
4352 various tp_print implementations of the built-in types and those in
4353 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00004362- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004363 PyObject_Call() never calling back out to Python code to trigger
4364 recursion depth updates/checks. Required the creation of a static
4365 RuntimeError instance in case normalizing an exception put the
4366 recursion check value past its limit. Fixes crashers
4367 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004382- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004383 __*__ attributes. (Some already existed, e.g., __doc__ and
4384 __name__.)

4390 calls.
4391
Collin Winter62903052007-05-18 23:11:24 +00004392- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004393 "except E as target:". This is to provide forwards compatibility
4394 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004401- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004402 setting a plain string, ie don't expand to single letter identifiers.
4403
Raymond Hettinger13936692007-04-11 18:40:58 +00004404- Request #1191699: Slices can now be pickled.
4405
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004406- Request #1193128: str.translate() now allows a None argument for
4407 translations that only remove characters without re-mapping the
4408 remaining characters.
4409
Georg Brandl5cb76c12007-03-21 09:00:39 +00004410- Patch #1682205: a TypeError while unpacking an iterable is no longer

4414
Guido van Rossum143b5642007-03-23 04:58:42 +00004415- Bug #1683368: The object.__init__() and object.__new__() methods are
4416 now stricter in rejecting excess arguments. The only time when
4417 either allows excess arguments is when it is not overridden and the
4418 other one is. For backwards compatibility, when both are
4419 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004420 warning later). Also, type.__init__() insists on the same signature
4421 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004422
Georg Brandl3ee81df2008-05-17 18:14:43 +00004423- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4424 object to complex using its __complex__() method before falling back
4425 to the __float__() method. Therefore, the functions in the cmath
4426 module now can operate on objects that define a __complex__()
4427 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004428
Georg Brandl3ee81df2008-05-17 18:14:43 +00004429- Patch #1623563: allow __class__ assignment for classes with
4430 __slots__. The old and the new class are still required to have the
4431 same slot names.

4438 its type.

4444
Georg Brandl7b9c5552007-03-12 14:30:05 +00004445- Bug #1678647: write a newline after printing an exception in any
4446 case, even when converting the value to a string failed.
4447
Georg Brandl871f1bc2007-03-12 13:17:36 +00004448- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004449 its argument, if it exists. If not, it will work like before. This
4450 allows customizing the output of dir() in the presence of a
4451 __getattr__().

4455
Georg Brandl3ee81df2008-05-17 18:14:43 +00004456- Patch #1675981: remove unreachable code from ``type.__new__()``

4460 parthensized forms. This means complex(repr(x)) now works instead of
4461 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004462
Georg Brandlaa2321b2007-03-07 00:40:28 +00004463- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004464 makes the filenames the warning module prints much more sensible
4465 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004478- Patch #1674228: when assigning a slice (old-style), check for the
4479 sq_ass_slice instead of the sq_slice slot.
4480
Georg Brandl3ee81df2008-05-17 18:14:43 +00004481- When printing an unraisable error, don't print exceptions. before
4482 the name. This duplicates the behavior whening normally printing
4483 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005034- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005051 are set for invalid interpolation sequences that would lead to

5108 TestCase and TestSuite subclasses (not instances) are no longer
5109 accepted in TestSuite.addTest(). This should cause no
5110 incompatibility since it never made sense with ordinary subclasses
5111 -- the failure just occurred later, with a more cumbersome
5112 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005399 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00005401 does not claim to support starttls. Adds the

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005500- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00005501 time so that opening a database previously created with the DB_DUP
5502 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5503 opens. Specifically: dictionary assignment to a DB object will
5504 replace all values for a given key when the database allows
5505 duplicate values. DB users should use DB.put(k, v) when they want
5506 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005786 periodic threadstate and signal checking in tight loops. By
5787 default, this option is turned-off. It should only be enabled in

5862 of w# format code incorrectly truncated the length to an int, even
5863 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5864 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005894- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5895 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005922- Removed the macfs module. It had been deprecated since Python 2.5.
5923 This lead to the deprecation of macostools.touched() as it relied
