104
Antoine Pitrou2c7d6852010-09-23 19:55:24 +0000105- Issue #9928: Properly initialize the types exported by the bz2 module.
106
Antoine Pitrou6391b342010-09-14 18:48:19 +0000107- Issue #9854: The default read() implementation in io.RawIOBase now
108 handles non-blocking readinto() returning None correctly.
109
Antoine Pitrouf7f390a2010-09-14 14:37:18 +0000110- Issue #9729: Fix the signature of SSLSocket.recvfrom() and
111 SSLSocket.sendto() to match the corresponding socket methods. Also,
112 fix various SSLSocket methods to raise socket.error rather than an
113 unhelpful TypeError when called on an unconnected socket. Original patch
114 by Andrew Bennetts.
115
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000116- Issue #9826: OrderedDict.__repr__ can now handle self-referential

125 This prevents user-created self-referencing ordered dictionaries from
126 becoming permanently uncollectable GC garbage. The downside is that
127 removing __del__ means that the internal doubly-linked list has to wait for
128 GC collection rather than freeing memory immediately when the refcnt drops
129 to zero.
130
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000131- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000132 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000133 value.

136 would swallow the exception and raise a new one, making it impossible
137 to fetch the original errno, or to filter timeout errors. Now the
138 original error is re-raised.
139
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000140- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
141 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
142 be updated back after the system call. Original patch by Brian Brazil.
143
Antoine Pitroudca9de92010-09-04 17:52:26 +0000144- Issue #1100562: Fix deep-copying of objects derived from the list and
145 dict types. Patch by Michele Orrù and Björn Lindqvist.
146
Fred Drakea1e627d2010-09-03 03:55:50 +0000147- Issue #7005: Fixed output of None values for RawConfigParser.write and
148 ConfigParser.write.
149
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000150- Issue #808164: Fixed socket.close to avoid references to globals, to
151 avoid issues when socket.close is called from a __del__ method.
152
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000153- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

157 character years even if the message contains RFC822 two character years.
158
Daniel Stutzbach91287322010-08-24 21:09:30 +0000159- Issue #8750: Fixed MutableSet's methods to correctly handle
160 reflexive operations, namely x -= x and x ^= x.
161
Victor Stinnercaafd772010-09-08 10:51:01 +0000162- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000163 error handling when accepting a new connection.

171 module now correctly return a set. (Patch by Eli Bendersky.)
172
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000173- Issue #9617: Signals received during a low-level write operation aren't
174 ignored by the buffered IO layer anymore.
175
Benjamin Peterson52c36052010-08-21 03:03:22 +0000176- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
177 are not held onto after they are deleted elsewhere.
178
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000179- Issue #9626: the view methods for collections.OrderedDict() were returning
180 the unordered versions inherited from dict. Those methods are now
181 overridden to provide ordered views.
182
Éric Araujo0389ae62010-08-14 03:07:46 +0000183- Issue #8688: MANIFEST files created by distutils now include a magic

215 This is how it is supposed to work, wget and curl do the same. Previous
216 behavior was wrong.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000937 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
938 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
939 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

959Core and Builtins
960-----------------
961
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000962- Issue #7301: Add environment variable $PYTHONWARNINGS.
963
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000964- Issue #8329: Don't return the same lists from select.select when no fds are
965 changed.
966
Georg Brandlfee0f442010-05-22 21:26:21 +0000967- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000968 on 64-bit machines. The shift count for either left or right shift is
969 permitted to be up to sys.maxsize.
970
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000971- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000975- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
976
Georg Brandlfee0f442010-05-22 21:26:21 +0000977- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
978 with a non-empty format string. This is an effort to future-proof user
979 code. If a derived class does not currently implement __format__ but later
980 adds its own __format__, it would most likely break user code that had
981 supplied a format string. This will be changed to a DeprecationWaring in
982 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000983
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000984- Issue #8268: Old-style classes (not just instances) now support weak

1008
Antoine Pitrouf9de5342010-04-05 21:35:07 +00001009- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +00001010 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

1014
Georg Brandlfee0f442010-05-22 21:26:21 +00001015- Issue #8257: The Decimal construct now accepts a float instance directly,
1016 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00001017
1018 >>> Decimal(1.1)
1019 Decimal('1.100000000000000088817841970012523233890533447265625')
1020
Raymond Hettinger34c35b22010-04-03 10:22:00 +00001021- collections.Counter() now supports a subtract() method.
1022
Georg Brandlfee0f442010-05-22 21:26:21 +00001023- The functools module now has a total_ordering() class decorator to simplify
1024 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00001025
Georg Brandlfee0f442010-05-22 21:26:21 +00001026- The functools module also adds cmp_to_key() as a tool to transition old-style
1027 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00001028
Georg Brandlfee0f442010-05-22 21:26:21 +00001029- Issue #8294: The Fraction constructor now accepts Decimal and float instances
1030 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00001031
Georg Brandlfee0f442010-05-22 21:26:21 +00001032- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1033 InvalidOperation instead of returning False. (Comparisons involving a quiet
1034 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1035 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001036
Georg Brandlfee0f442010-05-22 21:26:21 +00001037- Issue #2531: Comparison operations between floats and Decimal instances now
1038 return a result based on the numeric values of the operands; previously they
1039 returned an arbitrary result based on the relative ordering of id(float) and
1040 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00001041
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001042- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001043 argument `-` which tells it to read files to compile from stdin. Each line is
1044 read on demand and the named file is compiled immediately. (Original patch by
1045 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001046
Georg Brandlfee0f442010-05-22 21:26:21 +00001047- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00001050- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
1051 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00001052 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00001053
Georg Brandlfee0f442010-05-22 21:26:21 +00001054- Comparisons using one of <, <=, >, >= between a complex instance and a
1055 Fractions instance now raise TypeError instead of returning True/False. This
1056 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1057 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00001058

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00001068- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00001069 didn't support chflags() (for example ZFS under FreeBSD). The error is now

Vinay Sajipecfa08f2010-03-12 09:16:10 +00001112- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +00001113 for ``TimedRotatingFileHandler`` by using the modification time of an existing
1114 log file to compute the next rollover time. If the log file does not exist,
1115 the current time is used as the basis for the computation.

Georg Brandlba83f822010-03-14 09:50:54 +00001125- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
1126 a base64 transfer-encoded payload *after* decoding it; it no longer does.
1127 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +00001156- Issue #8300: When passing a non-integer argument to struct.pack with any
1157 integer format code, struct.pack first attempts to convert the non-integer
1158 using its __index__ method. If that method is non-existent or raises
1159 TypeError it goes on to try the __int__ method, as described below.
1160
Georg Brandlba83f822010-03-14 09:50:54 +00001161- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
1162 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
1163 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00001164 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
1165 inconsistent: __int__ was used for some integer codes but not for others, and
1166 the set of integer codes for which it was used differed between native packing
1167 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001464 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00001471 file position when calling `truncate()`. It would previously change the file
1472 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001473 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1474

1476 class used to represent files stored inside an archive. The new
1477 implementation is significantly faster and can be wrapped in a
1478 ``io.BufferedReader`` object for more speedups. It also solves an issue
1479 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001490- Issue #7748: Since unicode values are supported for some metadata options in
1491 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1492 encoded string for them. This ensures that the upload and register commands
1493 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001764- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1765 decimal string that's guaranteed to round back to x under correct rounding
1766 (with round-half-to-even rounding mode). Previously it gave a string based on
1767 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1768 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1769 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001770
Georg Brandlba83f822010-03-14 09:50:54 +00001771- Issue #7117: On almost all platforms: float-to-string and string-to-float
1772 conversions within Python are now correctly rounded. Places these conversions
1773 occur include: str for floats and complex numbers; the float and complex
1774 constructors; old-style and new-style numeric formatting; serialization and
1775 deserialization of floats and complex numbers using marshal, pickle and json;
1776 parsing of float and imaginary literals in Python code; Decimal-to-float
1777 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001778
Georg Brandlba83f822010-03-14 09:50:54 +00001779 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1780 providing correctly-rounded strtod and dtoa C functions. This code is
1781 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1782 the C compiler. There may be a small number of platforms on which correct
1783 operation of this code cannot be guaranteed, so the code is not used: notably,
1784 this applies to platforms where the C double format is not IEEE 754 binary64,
1785 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1786 and Python's configure script is unable to determine how to change the FPU
1787 precision. On these platforms conversions use the platform strtod and dtoa,
1788 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001790- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1791 uses the correctly-rounded string <-> float conversions described above (when
1792 available), and so produces correctly rounded results that will display nicely
1793 under the float repr. There are two related small changes: (1) round now
1794 accepts any class with an ``__index__()`` method for its second argument (but
1795 no longer accepts floats for the second argument), and (2) an excessively
1796 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1797 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00001944- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1945 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1946 but with at least one decimal point and with a default precision
1947 of 12. Previously, the behavior the same but with a default precision of 6.
1948 This more closely matches ``str()``, and reduces surprises when adding
1949 alignment flags to the empty presentation type. This also affects the new
1950 complex.__format__ in the same way.
1951
1952- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

2062
Benjamin Peterson596d3062009-01-19 15:42:23 +00002063- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

2147
Georg Brandlba83f822010-03-14 09:50:54 +00002148- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2149 file objects with closefd=False. The file descriptor is still kept open but
2150 the file object behaves like a closed file. The ``FileIO`` object also got a
2151 new readonly attribute ``closefd``.

2170
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002171- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00002174- On windows, ``os.chdir()`` given unicode was not working if
2175 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2176 this code path is really executed because I cannot move to such directory on
2177 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00002179- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2180 element is temporarily replaced with an equivalent frozenset. But the
2181 eventual KeyError would always report the empty ``frozenset()`` as the missing
2182 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002202- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2203 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2204 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2205 of using the replace error handler in PyUnicode_DecodeUTF8().
2206
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002207- Issue #3739: The unicode-internal encoder now reports the number of characters

2209
Georg Brandlba83f822010-03-14 09:50:54 +00002210- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2212 gives improved memory leak detection when running under Valgrind, while taking
2213 advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00002285 __main__.py file. This allows applications that run other Python scripts to
2286 support the same flexibility as the CPython command line itself.

3579
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003580- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3581 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3582 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3583 ``printf`` function, whereas PyString_FromFormat has an independent
3584 implementation and uses "%zd" on all platforms for size_t values.
3585 This makes a difference on win64, where ``printf`` needs "%Id" to display
3586 64bit values.

3592 object; previously an int would be returned for small values. the __long__

Antoine Pitrou0668c622008-08-26 22:42:08 +00003606 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3607 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3608 when given a tuple of classes as second argument, were looking up
3609 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3610 type object.

3707
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003708- Issue #2975: When compiling several extension modules with Visual Studio 2008
3709 from the same python interpreter, some environment variables would grow
3710 without limit.
3711
Benjamin Peterson37346b22008-08-23 20:27:43 +00003712- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003749What's New in Python 2.6 beta 3?
3750================================
3751
Barry Warsaw07a4a382008-08-21 01:15:08 +00003752*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003753
3754Core and Builtins
3755-----------------
3756
Guido van Rossumf8402962008-08-20 15:01:50 +00003757- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3758 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3759 extensions do not automatically benefit from the class attribute
3760 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3761 to their tp_flags field if they care. This is a backwards
3762 compatibility feature; in 3.0, all types will use the cache by
3763 default.
3764
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003765- Keyword arguments can now follow starred arguments. (``f(a, *args,
3766 keyword=23)`` is now valid syntax.)
3767
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003768- ctypes function pointers that are COM methods have a boolean True
3769 value again.
3770
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003771- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3772 by denying s# to parse objects that have a releasebuffer procedure,
3773 and introducing s*.
3774
Georg Brandl1e13ea92008-08-11 09:07:59 +00003775- Issue #3537: Fix an assertion failure when an empty but presized dict
3776 object was stored in the freelist.
3777
Mark Dickinsonb6467572008-08-04 21:30:09 +00003778- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3779 ValueError consistently across platforms.
3780
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003781- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3782 (64bit Unix, for example), unichr() would truncate its argument and return
3783 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3784
Neal Norwitze7d8be82008-07-31 17:17:14 +00003785- Apply security patches from Apple.
3786
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003787- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3788 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3789
Antoine Pitrou92f82162008-07-25 22:22:08 +00003790- Issue #1819: function calls with several named parameters are now on
3791 average 35% faster (as measured by pybench).
3792
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003793- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3794 the python debugger steps into a class statement: the free variables (local
3795 variables defined in an outer scope) would be deleted from the outer scope.
3796
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003797- Issue #2620: Overflow checking when allocating or reallocating memory
3798 was not always being done properly in some python types and extension
3799 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3800 all been updated to perform better checks and places in the code that
3801 would previously leak memory on the error path when such an allocation
3802 failed have been fixed.
3803
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003804Library
3805-------
3806
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003807- Issue #3612: Added some missing basic types in ctypes.wintypes.
3808
Benjamin Petersone977ad42008-08-20 01:42:01 +00003809- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3810 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3811
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003812- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3813 version reported by these tools does not necessarily follow the python
3814 version numbering scheme, so the module is less strict when parsing it.
3815
Nick Coghlanf70385a2008-08-18 12:42:46 +00003816- Issue #2235: Added Py3k warnings for types which will become unhashable
3817 under the stricter __hash__ inheritance rules in 3.0. Several types
3818 which did not meet the rules for hash invariants and were already
3819 unhashable in 3.0 have now been explicitly flagged as unhashable in
3820 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3821 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3822
Brett Cannon88f801d2008-08-18 00:46:22 +00003823- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3824 imported into the module but exposed as part of the module's API.
3825
Brett Cannon7b96f072008-08-18 00:41:11 +00003826- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3827
Brett Cannon46225e72008-08-18 00:36:52 +00003828- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003830- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3831
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003832- Issue #3575: Incremental decoder's decode function now takes bytearray
3833 by using 's*' instead of 't#'.
3834
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003835- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003836 fails unicode conversion on 2nd parameter. (windows only)
3837
Georg Brandl222e2082010-08-01 22:27:39 +00003838- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003839 in a redirect.
3840
Brett Cannonabe423e2008-08-16 21:47:07 +00003841- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003842 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003843
Facundo Batistaeb90b782008-08-16 14:44:07 +00003844- Issue #2776: fixed small issue when handling an URL with double slash
3845 after a 302 response in the case of not going through a proxy.
3846
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003847- Issue #2676: in the email package, content-type parsing was hanging on
3848 pathological input because of quadratic or exponential behaviour of a
3849 regular expression.
3850
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003851- Issue #3476: binary buffered reading through the new "io" library is now
3852 thread-safe.
3853
Brett Cannonbf3157b2008-08-14 05:00:03 +00003854- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3855 since mimetools itself is deprecated. Because modules are cached, all
3856 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3857
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003858- Issue #3134: shutil referenced undefined WindowsError symbol.
3859
Robert Schuppenies14646332008-08-10 11:01:53 +00003860- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3861 menu entries were not deleted.
3862
Brett Cannon83e81842008-08-09 23:30:55 +00003863- Copied the implementation of reduce() to _functools.reduce() to have a
3864 version that did not raise a DeprecationWarning under -3.
3865
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003866- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3867 a MemoryError rather than silently stop the iteration.
3868
Guido van Rossum59ce9012008-08-09 14:55:34 +00003869- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3870 to _sre.compile() will now be rejected. This should not affect anybody
3871 since the re.compile() function never generates invalid re-bytecode.
3872
Skip Montanaroa032bf42008-08-08 22:52:51 +00003873- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3874 upon first access it can be automatically initialized from the csv file if
3875 it wasn't initialized during instantiation.
3876
Brett Cannon3aa2a492008-08-06 22:28:09 +00003877- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3878 the reload() built-in has been removed.
3879
Brett Cannon7e30b672008-08-04 21:52:25 +00003880- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003881 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3889 raised an AttributeError.
3890
Benjamin Peterson01a24322008-07-28 23:35:27 +00003891- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003892 asking for a specific length. This problem only affected files opened
3893 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003894
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003895- Issue #3449: Update decimal module to use most recent specification
3896 (v. 1.68) and tests (v. 2.58) from IBM.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003918- Issue #3394: zipfile.writestr sets external attributes when passed a
3919 file name rather than a ZipInfo instance, so files are extracted with
3920 mode 0600 rather than 000 under Unix.
3921
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003922- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3923 argument in python 2.5, this broke code that subclassed Popen to include its
3924 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3935 interaction with the tp_hash slot (added in 2.6b2) are now documented
3936
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003937- Issue #643841: The language reference now provides more detailed
3938 coverage of the lookup process for special methods. The disclaimers
3939 regarding lack of coverage of new-style classes have also been
3940 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003943What's New in Python 2.6 beta 2?
3944================================
3945
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003946*Release date: 17-Jul-2008*
3947
Raymond Hettingere3ae6552008-06-20 04:18:15 +00003948Core and Builtins
3949-----------------
3950
Georg Brandl3e483f62008-07-16 22:57:41 +00003951- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3952 its methods now allow for items objects that can be converted to
3953 an integer using operator.index().
3954
Mark Dickinson64b7e502008-07-16 09:40:03 +00003955- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3956 produced a ValueError instead of giving the correct float.
3957
Eric Smitha5fa5a22008-07-16 00:11:49 +00003958- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3959 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3960
Mark Dickinson7103aa42008-07-15 19:08:33 +00003961- Issue #3008: the float type has a new instance method 'float.hex'
3962 and a new class method 'float.fromhex' to convert floating-point
3963 numbers to and from hexadecimal strings, respectively.
3964
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003965- Issue #2235: __hash__ is once again inherited by default. To allow
3966 collections.Hashable to remain meaningful in the presence of the
3967 default hash implementation (object.__hash__), it is now possible
3968 to explicit block inheritance of hash by setting __hash__=None at
3969 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3970 level.
3971
Nick Coghlanb028f502008-07-13 14:52:36 +00003972- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3973 the parent module cannot be found while performing an absolute import.
3974 This means that an incorrectly defined __package__ attribute will
3975 now only prevent relative imports in that module rather than causing

Georg Brandl5cc774e2008-06-11 20:28:06 +00004449 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004450
4451 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00004511- Issue #1631171: Re-implement the 'warnings' module in C (the
4512 original Python code has been kept as backup). This will allow for
4513 using the 'warning's machinery in such places as the parser where
4514 use of pure Python code is not possible. Both the ``showarning()``
4515 and ``formatwarning()`` gain an optional 'line' argument which is
4516 not called by default for backwards-compatibility reasons. Setting
4517 ``warnings.showwarning()`` to an implementation that lacks support
4518 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004581- Issue #2550: The approach used by client/server code for obtaining
4582 ports to listen on in network-oriented tests has been refined in an
4583 effort to facilitate running multiple instances of the entire
4584 regression test suite in parallel without issue.
4585 test_support.bind_port() has been fixed such that it will always
4586 return a unique port -- which wasn't always the case with the
4587 previous implementation, especially if socket options had been set
4588 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4589 new implementation of bind_port() will actually raise an exception
4590 if it is passed an AF_INET/SOCK_STREAM socket with either the
4591 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4592 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4593 the socket it's been passed. This currently only applies to
4594 Windows. This option prevents any other sockets from binding to the
4595 host/port we've bound to, thus removing the possibility of the
4596 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4597 when a second SOCK_STREAM socket binds and accepts to a host/port
4598 that's already been bound by another socket. The optional preferred
4599 port parameter to bind_port() has been removed. Under no
4600 circumstances should tests be hard coding ports!
4601
4602 test_support.find_unused_port() has also been introduced, which will
4603 pass a temporary socket object to bind_port() in order to obtain an
4604 unused port. The temporary socket object is then closed and
4605 deleted, and the port is returned. This method should only be used
4606 for obtaining an unused port in order to pass to an external program
4607 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4608 a parameter to a server-oriented class that doesn't give you direct
4609 access to the underlying socket used.
4610
4611 Finally, test_support.HOST has been introduced, which should be used
4612 for the host argument of any relevant socket calls (i.e. bind and
4613 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004614
4615 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004616 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004617 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4618 test_asynchat and test_socket_ssl.
4619
Georg Brandl3ee81df2008-05-17 18:14:43 +00004620 It is now possible for multiple instances of the regression test
4621 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004900- Added the future_builtins module, which contains hex() and oct().
4901 These are the PEP 3127 version of these functions, designed to be
4902 compatible with the hex() and oct() builtins from Python 3.0. They
4903 differ slightly in their output formats from the existing, unchanged
4904 Python 2.6 builtins. The expected usage of the future_builtins
4905 module is:
4906 from future_builtins import hex, oct
4907
Eric Smith7ef40bf2008-02-20 23:34:22 +00004908- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4909 exponents for exponents with absolute value < 100. Follows C99
4910 standard. This is a change on Windows, which would use 3 digits.
4911 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4912 so that any alterations it does to the resulting string will be
4913 available in stringlib/formatter.h (for float.__format__).
4914
Eric Smith5a3c1352008-02-19 13:21:56 +00004915- Implemented PEP 3101, Advanced String Formatting. This adds a new
4916 builtin format(); a format() method for str and unicode; a
4917 __format__() method to object, str, unicode, int, long, float, and
4918 datetime; the class string.Formatter; and the C API
4919 PyObject_Format().
4920
Georg Brandl3ee81df2008-05-17 18:14:43 +00004921- Fixed several potential crashes, all caused by specially crafted
4922 __del__ methods exploiting objects in temporarily inconsistent
4923 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004924
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004925- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004926 prevent a possible crash: an Abstract Base Class would try to access
4927 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004928

Georg Brandl3ee81df2008-05-17 18:14:43 +00004932- Clear all free lists during a gc.collect() of the highest generation
4933 in order to allow pymalloc to free more arenas. Python may give back
4934 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004935
Georg Brandl3ee81df2008-05-17 18:14:43 +00004936- Issue #2045: Fix an infinite recursion triggered when printing a
4937 subclass of collections.defaultdict, if its default_factory is set
4938 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004939
Christian Heimesf75dbef2008-02-08 00:11:31 +00004940- Fixed a minor memory leak in dictobject.c. The content of the free
4941 list was not freed on interpreter shutdown.
4942
Georg Brandl21e99f42010-03-07 15:23:59 +00004943- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004944 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004945
Georg Brandl3ee81df2008-05-17 18:14:43 +00004946- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4947 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004948 to compact the internal free lists of pre-allocted ints and floats.
4949
Georg Brandl3ee81df2008-05-17 18:14:43 +00004950- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4951 calls. Python expected the return type int but the fork familie
4952 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004953
Georg Brandl3ee81df2008-05-17 18:14:43 +00004954- Issue #1678380: Fix a bug that identifies 0j and -0j when they

4964 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004965
Georg Brandl3ee81df2008-05-17 18:14:43 +00004966- Patch #1473257: generator objects gain a gi_code attribute. This is
4967 the same object as the func_code attribute of the function that
4968 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004969
Georg Brandl3ee81df2008-05-17 18:14:43 +00004970- Issue #1920: "while 0" statements were completely removed by the
4971 compiler, even in the presence of an "else" clause, which is
4972 supposed to be run when the condition is false. Now the compiler
4973 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004974
Guido van Rossumeead05f2008-01-24 18:21:02 +00004975- A few crashers fixed: weakref_in_del.py (issue #1377858);
4976 loosing_dict_ref.py (issue #1303614, test67.py);
4977 borrowed_ref_[34].py (not in tracker).
4978
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004979- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004980 suppressed while an extension is loaded by calling SetErrorMode in

4982
Georg Brandl3ee81df2008-05-17 18:14:43 +00004983- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004984 several extension methods and modules do not work without unicode
4985 support.
4986
Georg Brandl26543b12008-01-21 18:36:51 +00004987- Issue #1882: when compiling code from a string, encoding cookies in the
4988 second line of code were not always recognized correctly.
4989
Georg Brandl14404b62008-01-19 19:27:05 +00004990- Issue #1679: "0x" was taken as a valid integer literal.
4991
Georg Brandl6caad7d2008-01-26 14:19:22 +00004992- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004993 added.
4994
Christian Heimesc94e2b52008-01-14 04:13:37 +00004995- sys.float_info / PyFloat_GetInfo: The floating point information
4996 object was converted from a dict to a specialized structseq object.
4997
Georg Brandl3ee81df2008-05-17 18:14:43 +00004998- Patch #1816: Added sys.flags structseq. It exposes the status of
4999 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005000
Georg Brandl3ee81df2008-05-17 18:14:43 +00005001- Objects/structseq.c: Implemented new structseq representation. The

5003 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005004
Georg Brandl3ee81df2008-05-17 18:14:43 +00005005- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00005027 and INF. float("nan"), float("inf") and float("-inf") now work on
5028 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005029
Georg Brandl3ee81df2008-05-17 18:14:43 +00005030- Compiler now generates simpler and faster code for dictionary
5031 literals. The oparg for BUILD_MAP now indicates an estimated
5032 dictionary size. There is a new opcode, STORE_MAP, for adding
5033 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005078 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5079 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005080
Georg Brandl3ee81df2008-05-17 18:14:43 +00005081- Issue #1686386: Tuple's tp_repr did not take into account the
5082 possibility of having a self-referential tuple, which is possible
5083 from C code. Nor did object's tp_str consider that a type's tp_str
5084 could do something that could lead to an inifinite recursion.
5085 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5086 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005088- Issue #1164: It was possible to trigger deadlock when using the
5089 'print' statement to write to a file since the GIL was not released
5090 as needed. Now PyObject_Print() does the right thing along with
5091 various tp_print implementations of the built-in types and those in
5092 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005102 PyObject_Call() never calling back out to Python code to trigger
5103 recursion depth updates/checks. Required the creation of a static
5104 RuntimeError instance in case normalizing an exception put the
5105 recursion check value past its limit. Fixes crashers

5130
Collin Winter62903052007-05-18 23:11:24 +00005131- except clauses may now be spelled either "except E, target:" or

5153
Guido van Rossum143b5642007-03-23 04:58:42 +00005154- Bug #1683368: The object.__init__() and object.__new__() methods are
5155 now stricter in rejecting excess arguments. The only time when
5156 either allows excess arguments is when it is not overridden and the
5157 other one is. For backwards compatibility, when both are
5158 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005159 warning later). Also, type.__init__() insists on the same signature
5160 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005162- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5163 object to complex using its __complex__() method before falling back
5164 to the __float__() method. Therefore, the functions in the cmath
5165 module now can operate on objects that define a __complex__()
5166 method.

5183
Georg Brandl7b9c5552007-03-12 14:30:05 +00005184- Bug #1678647: write a newline after printing an exception in any
5185 case, even when converting the value to a string failed.
5186
Georg Brandl871f1bc2007-03-12 13:17:36 +00005187- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005188 its argument, if it exists. If not, it will work like before. This
5189 allows customizing the output of dir() in the presence of a
5190 __getattr__().

5200 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005201
Georg Brandlaa2321b2007-03-07 00:40:28 +00005202- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005203 makes the filenames the warning module prints much more sensible
5204 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005217- Patch #1674228: when assigning a slice (old-style), check for the
5218 sq_ass_slice instead of the sq_slice slot.
5219
Georg Brandl3ee81df2008-05-17 18:14:43 +00005220- When printing an unraisable error, don't print exceptions. before

Georg Brandl92a6bae2007-03-13 17:43:32 +00005789- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005790 are set for invalid interpolation sequences that would lead to

5847 TestCase and TestSuite subclasses (not instances) are no longer
5848 accepted in TestSuite.addTest(). This should cause no

5851 exception.

6134 obtained from the TLS negotiation itself. Patch contributed by Bill
6135 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006136
Georg Brandl3ee81df2008-05-17 18:14:43 +00006137- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006138 that the SMTP.starttls() caller no longer needs to call ehlo()
6139 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006140 does not claim to support starttls. Adds the
6141 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00006225

Georg Brandl3ee81df2008-05-17 18:14:43 +00006240 time so that opening a database previously created with the DB_DUP
6241 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6242 opens. Specifically: dictionary assignment to a DB object will
6243 replace all values for a given key when the database allows
6244 duplicate values. DB users should use DB.put(k, v) when they want
6245 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006246

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00006524- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00006525 periodic threadstate and signal checking in tight loops. By
6526 default, this option is turned-off. It should only be enabled in
6527 debugged, performance critical applications.

6578-----
6579
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580- Unified naming convention for free lists and their limits. All free
6581 lists in Object/ are named ``free_list``, the counter ``numfree``
6582 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6583 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006584
Georg Brandl3ee81df2008-05-17 18:14:43 +00006585- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6586 to ``PyTuple_SetItem``, it can be used to populate a brand new
6587 frozenset; but it does not steal a reference to the added item.

6599
Georg Brandl3ee81df2008-05-17 18:14:43 +00006600- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6601 of w# format code incorrectly truncated the length to an int, even
6602 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6603 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006604
Georg Brandl3ee81df2008-05-17 18:14:43 +00006605- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

6625
6626- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6627 outside of pystate.c and should not be necessary.
6628
Georg Brandl3ee81df2008-05-17 18:14:43 +00006629- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6630 absolute imports. In earlier versions they might have used relative
6631 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006632
Georg Brandl3ee81df2008-05-17 18:14:43 +00006633- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6634 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006635
Georg Brandl3ee81df2008-05-17 18:14:43 +00006636- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006661- Removed the macfs module. It had been deprecated since Python 2.5.
6662 This lead to the deprecation of macostools.touched() as it relied
6663 solely on macfs and was a no-op under OS X.
