Ned Deily18fae3f2013-01-31 01:24:55 -08001532- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1533 In particular, fix extension module build failures when trying to use
1534 32-bit-only installer Pythons on systems with Xcode 4 (currently
1535 OS X 10.8, 10.7, and optionally 10.6).
1536 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1537 * Since Xcode 4 removes ppc support, extension module builds now
1538 check for ppc compiler support and by default remove ppc and
1539 ppc64 archs when they are not available.
1540 * Extension module builds now revert to using system installed
1541 headers and libs (/usr and /System/Library) if the SDK used
1542 to build the interpreter is not installed or has moved.
1543 * Try to avoid building extension modules with deprecated
1544 and problematic Apple llvm-gcc compiler. If original compiler
1545 is not available, use clang instead by default.

1900 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +01001976- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1977 Distutils-based packages with C extension modules may fail because
1978 Apple has removed gcc-4.2, the version used to build python.org
1979 64-bit/32-bit Pythons. If the user does not explicitly override
1980 the default C compiler by setting the CC environment variable,
1981 Distutils will now attempt to compile extension modules with clang
1982 if gcc-4.2 is required but not found. Also as a convenience, if
1983 the user does explicitly set CC, substitute its value as the default
1984 compiler in the Distutils LDSHARED configuration variable for OS X.
1985 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1986 SDK, neither of which are available in Xcode 4. This change does not
1987 attempt to override settings to support their use with Xcode 4.)

2097 arguments with the system default encoding just like the write() method

Ned Deily87e82bb2011-06-28 19:52:59 -07002237- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2238 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2239 interpreter process. This could cause failures in non-Distutils subprocesses
2240 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002241 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002242 deployment target only in the environment of each build subprocess. It is
2243 still possible to globally override the default by setting
2244 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2245 greater or equal to the default value, the value with which the interpreter
2246 was built.

2273
Barry Warsawc5643282011-07-19 17:06:30 -04002274- sys.setcheckinterval() now updates the current ticker count as well as
2275 updating the check interval, so if the user decreases the check interval,
2276 the ticker doesn't have to wind down to zero from the old starting point
2277 before the new interval takes effect. And if the user increases the
2278 interval, it makes sure the new limit takes effect right away rather have an
2279 early task switch before recognizing the new interval.

3227 with invalid characters after '=' in a Q-encoded word.
3228
Antoine Pitrou66b5df62010-09-27 18:16:46 +00003229- Issue #9950: Fix socket.sendall() crash or misbehaviour when a signal is
3230 received. Now sendall() properly calls signal handlers if necessary,

3243 handles non-blocking readinto() returning None correctly.

3249 by Andrew Bennetts.
3250

3258
Raymond Hettinger20397532010-09-12 02:11:45 +00003259- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3260 This prevents user-created self-referencing ordered dictionaries from
3261 becoming permanently uncollectable GC garbage. The downside is that
3262 removing __del__ means that the internal doubly-linked list has to wait for
3263 GC collection rather than freeing memory immediately when the refcnt drops
3264 to zero.
3265
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003266- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +00003267 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003268 value.
3269
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003270- Issue #9792: In case of connection failure, socket.create_connection()
3271 would swallow the exception and raise a new one, making it impossible
3272 to fetch the original errno, or to filter timeout errors. Now the
3273 original error is re-raised.
3274
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003275- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
3276 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
3277 be updated back after the system call. Original patch by Brian Brazil.
3278
Antoine Pitroudca9de92010-09-04 17:52:26 +00003279- Issue #1100562: Fix deep-copying of objects derived from the list and

3283 ConfigParser.write.
3284
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003285- Issue #808164: Fixed socket.close to avoid references to globals, to
3286 avoid issues when socket.close is called from a __del__ method.
3287
Terry Reedyd2d2ae92010-11-11 23:22:19 +00003288- Issue #2986: difflib.SequenceMatcher gets a new parameter, autojunk, which
3289 can be set to False to turn off the previously undocumented 'popularity'
3290 heuristic. Patch by Terry Reedy and Eli Bendersky
3291
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00003292- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
3293 falling into recursion.
3294
R. David Murray7c4bf552010-08-25 01:45:57 +00003295- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3296 character years even if the message contains RFC822 two character years.
3297
Daniel Stutzbach91287322010-08-24 21:09:30 +00003298- Issue #8750: Fixed MutableSet's methods to correctly handle

3310 module now correctly return a set. (Patch by Eli Bendersky.)
3311
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003312- Issue #9617: Signals received during a low-level write operation aren't
3313 ignored by the buffered IO layer anymore.
3314
Benjamin Peterson52c36052010-08-21 03:03:22 +00003315- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3316 are not held onto after they are deleted elsewhere.
3317
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003318- Issue #9626: the view methods for collections.OrderedDict() were returning

3329
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003330- Issue #9550: a BufferedReader could issue an additional read when the
3331 original read request had been satisfied, which could block indefinitely
3332 when the underlying raw IO channel was e.g. a socket. Report and original
3333 patch by Jason V. Miller.
3334
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003335- Issue #9551: Don't raise TypeError when setting the value to None for

3354 This is how it is supposed to work, wget and curl do the same. Previous
3355 behavior was wrong.

3363 the option character for the added 'h/help' option if prefix_chars
3364 does not contain a '-', instead of raising an error.
3365

3725 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

3738 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00004083 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

4105Core and Builtins
4106-----------------
4107
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004108- Issue #7301: Add environment variable $PYTHONWARNINGS.
4109
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004110- Issue #8329: Don't return the same lists from select.select when no fds are
4111 changed.
4112
Georg Brandlfee0f442010-05-22 21:26:21 +00004113- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004114 on 64-bit machines. The shift count for either left or right shift is
4115 permitted to be up to sys.maxsize.
4116
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004117- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00004119- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00004120
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00004121- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
4122
Georg Brandlfee0f442010-05-22 21:26:21 +00004123- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4124 with a non-empty format string. This is an effort to future-proof user
4125 code. If a derived class does not currently implement __format__ but later
4126 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004127 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004128 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00004129
Antoine Pitroua57df2c2010-03-31 21:32:15 +00004130- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00004143- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00004144 (SIGINT). If an error occurs while importing the site module, the error is
4145 printed and Python exits. Initialize the GIL before importing the site

4160
Georg Brandlfee0f442010-05-22 21:26:21 +00004161- Issue #8257: The Decimal construct now accepts a float instance directly,
4162 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004163
4164 >>> Decimal(1.1)
4165 Decimal('1.100000000000000088817841970012523233890533447265625')
4166
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004167- collections.Counter() now supports a subtract() method.
4168
Georg Brandlfee0f442010-05-22 21:26:21 +00004169- The functools module now has a total_ordering() class decorator to simplify
4170 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00004178- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4179 InvalidOperation instead of returning False. (Comparisons involving a quiet
4180 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4181 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004182
Georg Brandlfee0f442010-05-22 21:26:21 +00004183- Issue #2531: Comparison operations between floats and Decimal instances now
4184 return a result based on the numeric values of the operands; previously they
4185 returned an arbitrary result based on the relative ordering of id(float) and
4186 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004187
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004188- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004189 argument `-` which tells it to read files to compile from stdin. Each line is
4190 read on demand and the named file is compiled immediately. (Original patch by
4191 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004196- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4197 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004198 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00004199
Georg Brandlfee0f442010-05-22 21:26:21 +00004200- Comparisons using one of <, <=, >, >= between a complex instance and a
4201 Fractions instance now raise TypeError instead of returning True/False. This
4202 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4203 <=> complex, and complex <=> complex comparisons.

4312 the set of integer codes for which it was used differed between native packing
4313 and standard packing.)

4566 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4567 returning NULL. The macro now returns a statically allocated empty string
4568 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004621 file position when calling `truncate()`. It would previously change the file
4622 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004623 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4626 class used to represent files stored inside an archive. The new
4627 implementation is significantly faster and can be wrapped in a
4628 ``io.BufferedReader`` object for more speedups. It also solves an issue
4629 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4642 encoded string for them. This ensures that the upload and register commands
4643 send the correct values to PyPI without any error.

4729 effects of this change are in the extension modules, but some core functions
4730 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4731 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004913- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4914 decimal string that's guaranteed to round back to x under correct rounding
4915 (with round-half-to-even rounding mode). Previously it gave a string based on
4916 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4917 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4918 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004919
Georg Brandlba83f822010-03-14 09:50:54 +00004920- Issue #7117: On almost all platforms: float-to-string and string-to-float
4921 conversions within Python are now correctly rounded. Places these conversions
4922 occur include: str for floats and complex numbers; the float and complex
4923 constructors; old-style and new-style numeric formatting; serialization and
4924 deserialization of floats and complex numbers using marshal, pickle and json;
4925 parsing of float and imaginary literals in Python code; Decimal-to-float
4926 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004927
Georg Brandlba83f822010-03-14 09:50:54 +00004928 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4929 providing correctly-rounded strtod and dtoa C functions. This code is
4930 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4931 the C compiler. There may be a small number of platforms on which correct
4932 operation of this code cannot be guaranteed, so the code is not used: notably,
4933 this applies to platforms where the C double format is not IEEE 754 binary64,
4934 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4935 and Python's configure script is unable to determine how to change the FPU
4936 precision. On these platforms conversions use the platform strtod and dtoa,
4937 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004939- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4940 uses the correctly-rounded string <-> float conversions described above (when
4941 available), and so produces correctly rounded results that will display nicely
4942 under the float repr. There are two related small changes: (1) round now
4943 accepts any class with an ``__index__()`` method for its second argument (but
4944 no longer accepts floats for the second argument), and (2) an excessively
4945 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4946 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005323- On windows, ``os.chdir()`` given unicode was not working if

5325 this code path is really executed because I cannot move to such directory on
5326 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005328- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5329 element is temporarily replaced with an equivalent frozenset. But the
5330 eventual KeyError would always report the empty ``frozenset()`` as the missing

5352 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5353 step. This avoids problems with counting UTF-8 bytes that ignores the effect

5355
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005356- Issue #3739: The unicode-internal encoder now reports the number of characters

Nick Coghlan49868cb2009-11-15 07:30:34 +00005434 __main__.py file. This allows applications that run other Python scripts to
5435 support the same flexibility as the CPython command line itself.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006732- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6733 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6734 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6735 ``printf`` function, whereas PyString_FromFormat has an independent
6736 implementation and uses "%zd" on all platforms for size_t values.
6737 This makes a difference on win64, where ``printf`` needs "%Id" to display
6738 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00006758 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00006833 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6834 for catch_warnings() also led to an improvement in the raising of a
6835 DeprecationWarning related to warnings.warn_explicit().
6836
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006837- The deprecation warnings for the old camelCase threading API were removed.

6859
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006860- Issue #2975: When compiling several extension modules with Visual Studio 2008
6861 from the same python interpreter, some environment variables would grow
6862 without limit.
6863
Benjamin Peterson37346b22008-08-23 20:27:43 +00006864- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
6865 exploitation of poor argument checking.
6866
Gerhard Häringef2276b2008-09-12 13:54:06 +00006867- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006901What's New in Python 2.6 beta 3?
6902================================
6903
Barry Warsaw07a4a382008-08-21 01:15:08 +00006904*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006905
6906Core and Builtins
6907-----------------
6908
Guido van Rossumf8402962008-08-20 15:01:50 +00006909- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6910 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6911 extensions do not automatically benefit from the class attribute
6912 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6913 to their tp_flags field if they care. This is a backwards
6914 compatibility feature; in 3.0, all types will use the cache by
6915 default.
6916
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006917- Keyword arguments can now follow starred arguments. (``f(a, *args,
6918 keyword=23)`` is now valid syntax.)
6919
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006920- ctypes function pointers that are COM methods have a boolean True
6921 value again.
6922
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006923- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6924 by denying s# to parse objects that have a releasebuffer procedure,
6925 and introducing s*.
6926
Georg Brandl1e13ea92008-08-11 09:07:59 +00006927- Issue #3537: Fix an assertion failure when an empty but presized dict
6928 object was stored in the freelist.
6929
Mark Dickinsonb6467572008-08-04 21:30:09 +00006930- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6931 ValueError consistently across platforms.
6932
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006933- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6934 (64bit Unix, for example), unichr() would truncate its argument and return
6935 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6936
Neal Norwitze7d8be82008-07-31 17:17:14 +00006937- Apply security patches from Apple.
6938
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006939- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6940 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6941
Antoine Pitrou92f82162008-07-25 22:22:08 +00006942- Issue #1819: function calls with several named parameters are now on
6943 average 35% faster (as measured by pybench).
6944
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006945- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6946 the python debugger steps into a class statement: the free variables (local
6947 variables defined in an outer scope) would be deleted from the outer scope.
6948
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006949- Issue #2620: Overflow checking when allocating or reallocating memory
6950 was not always being done properly in some python types and extension
6951 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6952 all been updated to perform better checks and places in the code that
6953 would previously leak memory on the error path when such an allocation
6954 failed have been fixed.
6955

6957-------
6958
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006959- Issue #3612: Added some missing basic types in ctypes.wintypes.
6960
Benjamin Petersone977ad42008-08-20 01:42:01 +00006961- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6962 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6963
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006964- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6965 version reported by these tools does not necessarily follow the python
6966 version numbering scheme, so the module is less strict when parsing it.
6967
Nick Coghlanf70385a2008-08-18 12:42:46 +00006968- Issue #2235: Added Py3k warnings for types which will become unhashable
6969 under the stricter __hash__ inheritance rules in 3.0. Several types
6970 which did not meet the rules for hash invariants and were already
6971 unhashable in 3.0 have now been explicitly flagged as unhashable in
6972 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6973 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6974
Brett Cannon88f801d2008-08-18 00:46:22 +00006975- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6976 imported into the module but exposed as part of the module's API.
6977
Brett Cannon7b96f072008-08-18 00:41:11 +00006978- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6979
Brett Cannon46225e72008-08-18 00:36:52 +00006980- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006982- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6983
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006984- Issue #3575: Incremental decoder's decode function now takes bytearray
6985 by using 's*' instead of 't#'.
6986
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006987- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006988 fails unicode conversion on 2nd parameter. (windows only)
6989
Georg Brandl222e2082010-08-01 22:27:39 +00006990- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006991 in a redirect.
6992
Brett Cannonabe423e2008-08-16 21:47:07 +00006993- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006994 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006995
Facundo Batistaeb90b782008-08-16 14:44:07 +00006996- Issue #2776: fixed small issue when handling an URL with double slash
6997 after a 302 response in the case of not going through a proxy.
6998
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006999- Issue #2676: in the email package, content-type parsing was hanging on
7000 pathological input because of quadratic or exponential behaviour of a
7001 regular expression.
7002
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007003- Issue #3476: binary buffered reading through the new "io" library is now
7004 thread-safe.
7005
Brett Cannonbf3157b2008-08-14 05:00:03 +00007006- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7007 since mimetools itself is deprecated. Because modules are cached, all
7008 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7009
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007010- Issue #3134: shutil referenced undefined WindowsError symbol.
7011
Robert Schuppenies14646332008-08-10 11:01:53 +00007012- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7013 menu entries were not deleted.
7014
Brett Cannon83e81842008-08-09 23:30:55 +00007015- Copied the implementation of reduce() to _functools.reduce() to have a
7016 version that did not raise a DeprecationWarning under -3.
7017
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007018- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7019 a MemoryError rather than silently stop the iteration.
7020
Guido van Rossum59ce9012008-08-09 14:55:34 +00007021- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7022 to _sre.compile() will now be rejected. This should not affect anybody
7023 since the re.compile() function never generates invalid re-bytecode.
7024
Skip Montanaroa032bf42008-08-08 22:52:51 +00007025- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7026 upon first access it can be automatically initialized from the csv file if
7027 it wasn't initialized during instantiation.
7028
Brett Cannon3aa2a492008-08-06 22:28:09 +00007029- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7030 the reload() built-in has been removed.
7031
Brett Cannon7e30b672008-08-04 21:52:25 +00007032- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007033 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007044 asking for a specific length. This problem only affected files opened
7045 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007046

7071 file name rather than a ZipInfo instance, so files are extracted with
7072 mode 0600 rather than 000 under Unix.
7073

7091 regarding lack of coverage of new-style classes have also been
7092 removed, since the coverage is now fairly reasonable.

Georg Brandl3e483f62008-07-16 22:57:41 +00007103- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7104 its methods now allow for items objects that can be converted to
7105 an integer using operator.index().
7106
Mark Dickinson64b7e502008-07-16 09:40:03 +00007107- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7108 produced a ValueError instead of giving the correct float.
7109
Eric Smitha5fa5a22008-07-16 00:11:49 +00007110- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Nick Coghlan6d6bd442008-07-15 15:40:22 +00007117- Issue #2235: __hash__ is once again inherited by default. To allow
7118 collections.Hashable to remain meaningful in the presence of the
7119 default hash implementation (object.__hash__), it is now possible
7120 to explicit block inheritance of hash by setting __hash__=None at
7121 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7122 level.
7123
Nick Coghlanb028f502008-07-13 14:52:36 +00007124- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7125 the parent module cannot be found while performing an absolute import.
7126 This means that an incorrectly defined __package__ attribute will
7127 now only prevent relative imports in that module rather than causing
7128 all imports from that module to fail.
7129
Nick Coghlan14ff9942008-07-08 14:21:42 +00007130- Issue #2517: Allow unicode messages in Exceptions again by correctly

7141
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007142- Issue #3004: Minor change to slice.indices(): the start and stop
7143 arguments are now treated identically, making the behaviour easier
7144 to describe and understand. For example, slice(None, -10,
7145 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7146 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7147 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007149- Issue #3219: Calling a function with repeated keyword arguments,
7150 f(a=2, a=23), would not cause a syntax error. This was a regression
7151 from 2.4 caused by the switch to the new compiler.

7190 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007191 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00007599 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007600
7601 This is controlled by the configure argument ``--with-universal-archs``:
7602
7603 - ``--with-universal-archs=all``: install 4-way universal
7604
7605 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7606
7607 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7608
7609 This option should be used in combination with ``--enable-universalsdk=``.

7647 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00007648
Christian Heimese74c8f22008-04-19 02:23:57 +00007649- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007660- Issue #1631171: Re-implement the 'warnings' module in C (the
7661 original Python code has been kept as backup). This will allow for
7662 using the 'warning's machinery in such places as the parser where
7663 use of pure Python code is not possible. Both the ``showarning()``
7664 and ``formatwarning()`` gain an optional 'line' argument which is
7665 not called by default for backwards-compatibility reasons. Setting
7666 ``warnings.showwarning()`` to an implementation that lacks support
7667 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007730- Issue #2550: The approach used by client/server code for obtaining
7731 ports to listen on in network-oriented tests has been refined in an
7732 effort to facilitate running multiple instances of the entire
7733 regression test suite in parallel without issue.
7734 test_support.bind_port() has been fixed such that it will always
7735 return a unique port -- which wasn't always the case with the
7736 previous implementation, especially if socket options had been set
7737 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7738 new implementation of bind_port() will actually raise an exception
7739 if it is passed an AF_INET/SOCK_STREAM socket with either the
7740 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7741 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7742 the socket it's been passed. This currently only applies to
7743 Windows. This option prevents any other sockets from binding to the
7744 host/port we've bound to, thus removing the possibility of the
7745 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7746 when a second SOCK_STREAM socket binds and accepts to a host/port
7747 that's already been bound by another socket. The optional preferred
7748 port parameter to bind_port() has been removed. Under no
7749 circumstances should tests be hard coding ports!
7750
7751 test_support.find_unused_port() has also been introduced, which will
7752 pass a temporary socket object to bind_port() in order to obtain an
7753 unused port. The temporary socket object is then closed and
7754 deleted, and the port is returned. This method should only be used
7755 for obtaining an unused port in order to pass to an external program
7756 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7757 a parameter to a server-oriented class that doesn't give you direct
7758 access to the underlying socket used.
7759
7760 Finally, test_support.HOST has been introduced, which should be used
7761 for the host argument of any relevant socket calls (i.e. bind and
7762 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007763
7764 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007765 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007766 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7767 test_asynchat and test_socket_ssl.
7768
Georg Brandl3ee81df2008-05-17 18:14:43 +00007769 It is now possible for multiple instances of the regression test
7770 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008049- Added the future_builtins module, which contains hex() and oct().
8050 These are the PEP 3127 version of these functions, designed to be
8051 compatible with the hex() and oct() builtins from Python 3.0. They
8052 differ slightly in their output formats from the existing, unchanged
8053 Python 2.6 builtins. The expected usage of the future_builtins
8054 module is:
8055 from future_builtins import hex, oct
8056
Eric Smith7ef40bf2008-02-20 23:34:22 +00008057- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8058 exponents for exponents with absolute value < 100. Follows C99
8059 standard. This is a change on Windows, which would use 3 digits.
8060 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8061 so that any alterations it does to the resulting string will be
8062 available in stringlib/formatter.h (for float.__format__).
8063
Eric Smith5a3c1352008-02-19 13:21:56 +00008064- Implemented PEP 3101, Advanced String Formatting. This adds a new
8065 builtin format(); a format() method for str and unicode; a
8066 __format__() method to object, str, unicode, int, long, float, and
8067 datetime; the class string.Formatter; and the C API
8068 PyObject_Format().
8069
Georg Brandl3ee81df2008-05-17 18:14:43 +00008070- Fixed several potential crashes, all caused by specially crafted
8071 __del__ methods exploiting objects in temporarily inconsistent
8072 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008073
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008074- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008075 prevent a possible crash: an Abstract Base Class would try to access
8076 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008077

Georg Brandl3ee81df2008-05-17 18:14:43 +00008081- Clear all free lists during a gc.collect() of the highest generation
8082 in order to allow pymalloc to free more arenas. Python may give back
8083 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008084
Georg Brandl3ee81df2008-05-17 18:14:43 +00008085- Issue #2045: Fix an infinite recursion triggered when printing a
8086 subclass of collections.defaultdict, if its default_factory is set
8087 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008088
Christian Heimesf75dbef2008-02-08 00:11:31 +00008089- Fixed a minor memory leak in dictobject.c. The content of the free
8090 list was not freed on interpreter shutdown.
8091
Georg Brandl21e99f42010-03-07 15:23:59 +00008092- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008093 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00008094
Georg Brandl3ee81df2008-05-17 18:14:43 +00008095- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8096 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008097 to compact the internal free lists of pre-allocted ints and floats.
8098
Georg Brandl3ee81df2008-05-17 18:14:43 +00008099- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8100 calls. Python expected the return type int but the fork familie
8101 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008102
Georg Brandl3ee81df2008-05-17 18:14:43 +00008103- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00008115- Patch #1473257: generator objects gain a gi_code attribute. This is
8116 the same object as the func_code attribute of the function that
8117 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008118
Georg Brandl3ee81df2008-05-17 18:14:43 +00008119- Issue #1920: "while 0" statements were completely removed by the
8120 compiler, even in the presence of an "else" clause, which is
8121 supposed to be run when the condition is false. Now the compiler
8122 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008123
Guido van Rossumeead05f2008-01-24 18:21:02 +00008124- A few crashers fixed: weakref_in_del.py (issue #1377858);
8125 loosing_dict_ref.py (issue #1303614, test67.py);
8126 borrowed_ref_[34].py (not in tracker).
8127
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008128- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008129 suppressed while an extension is loaded by calling SetErrorMode in

8131
Georg Brandl3ee81df2008-05-17 18:14:43 +00008132- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008133 several extension methods and modules do not work without unicode
8134 support.
8135
Georg Brandl26543b12008-01-21 18:36:51 +00008136- Issue #1882: when compiling code from a string, encoding cookies in the
8137 second line of code were not always recognized correctly.
8138
Georg Brandl14404b62008-01-19 19:27:05 +00008139- Issue #1679: "0x" was taken as a valid integer literal.
8140
Georg Brandl6caad7d2008-01-26 14:19:22 +00008141- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008142 added.
8143
Christian Heimesc94e2b52008-01-14 04:13:37 +00008144- sys.float_info / PyFloat_GetInfo: The floating point information
8145 object was converted from a dict to a specialized structseq object.
8146
Georg Brandl3ee81df2008-05-17 18:14:43 +00008147- Patch #1816: Added sys.flags structseq. It exposes the status of
8148 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008149
Georg Brandl3ee81df2008-05-17 18:14:43 +00008150- Objects/structseq.c: Implemented new structseq representation. The

8152 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008153
Georg Brandl3ee81df2008-05-17 18:14:43 +00008154- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00008179- Compiler now generates simpler and faster code for dictionary
8180 literals. The oparg for BUILD_MAP now indicates an estimated
8181 dictionary size. There is a new opcode, STORE_MAP, for adding
8182 entries to the dictionary.

8212 file can now be directly executed by passing their name to the
8213 interpreter. The directory/zipfile is automatically inserted as the
8214 first entry in sys.path.

8225
Georg Brandl21e99f42010-03-07 15:23:59 +00008226- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008227 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8228 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008229
Georg Brandl3ee81df2008-05-17 18:14:43 +00008230- Issue #1686386: Tuple's tp_repr did not take into account the
8231 possibility of having a self-referential tuple, which is possible
8232 from C code. Nor did object's tp_str consider that a type's tp_str
8233 could do something that could lead to an inifinite recursion.
8234 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8235 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008236
Georg Brandl3ee81df2008-05-17 18:14:43 +00008237- Issue #1164: It was possible to trigger deadlock when using the
8238 'print' statement to write to a file since the GIL was not released
8239 as needed. Now PyObject_Print() does the right thing along with
8240 various tp_print implementations of the built-in types and those in
8241 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008242
Georg Brandl3ee81df2008-05-17 18:14:43 +00008243- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00008250- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008251 PyObject_Call() never calling back out to Python code to trigger
8252 recursion depth updates/checks. Required the creation of a static
8253 RuntimeError instance in case normalizing an exception put the
8254 recursion check value past its limit. Fixes crashers
8255 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008270- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008271 __*__ attributes. (Some already existed, e.g., __doc__ and
8272 __name__.)

8278 calls.
8279
Collin Winter62903052007-05-18 23:11:24 +00008280- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008281 "except E as target:". This is to provide forwards compatibility
8282 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008289- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008290 setting a plain string, ie don't expand to single letter identifiers.
8291
Raymond Hettinger13936692007-04-11 18:40:58 +00008292- Request #1191699: Slices can now be pickled.
8293
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008294- Request #1193128: str.translate() now allows a None argument for
8295 translations that only remove characters without re-mapping the
8296 remaining characters.
8297
Georg Brandl5cb76c12007-03-21 09:00:39 +00008298- Patch #1682205: a TypeError while unpacking an iterable is no longer

8302
Guido van Rossum143b5642007-03-23 04:58:42 +00008303- Bug #1683368: The object.__init__() and object.__new__() methods are
8304 now stricter in rejecting excess arguments. The only time when
8305 either allows excess arguments is when it is not overridden and the
8306 other one is. For backwards compatibility, when both are
8307 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008308 warning later). Also, type.__init__() insists on the same signature
8309 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008310
Georg Brandl3ee81df2008-05-17 18:14:43 +00008311- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8312 object to complex using its __complex__() method before falling back
8313 to the __float__() method. Therefore, the functions in the cmath
8314 module now can operate on objects that define a __complex__()
8315 method.

8319 same slot names.

8326 its type.

8332
Georg Brandl7b9c5552007-03-12 14:30:05 +00008333- Bug #1678647: write a newline after printing an exception in any
8334 case, even when converting the value to a string failed.
8335
Georg Brandl871f1bc2007-03-12 13:17:36 +00008336- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008337 its argument, if it exists. If not, it will work like before. This
8338 allows customizing the output of dir() in the presence of a
8339 __getattr__().

8343
Georg Brandl3ee81df2008-05-17 18:14:43 +00008344- Patch #1675981: remove unreachable code from ``type.__new__()``

8348 parthensized forms. This means complex(repr(x)) now works instead of
8349 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008350
Georg Brandlaa2321b2007-03-07 00:40:28 +00008351- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008352 makes the filenames the warning module prints much more sensible
8353 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008366- Patch #1674228: when assigning a slice (old-style), check for the
8367 sq_ass_slice instead of the sq_slice slot.
8368
Georg Brandl3ee81df2008-05-17 18:14:43 +00008369- When printing an unraisable error, don't print exceptions. before
8370 the name. This duplicates the behavior whening normally printing
8371 exceptions.

Georg Brandl4e933132006-09-06 20:05:58 +00008454- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

8936
Georg Brandl92a6bae2007-03-13 17:43:32 +00008937- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008938 are set for invalid interpolation sequences that would lead to
8939 errors on reading back those values.

8995 TestCase and TestSuite subclasses (not instances) are no longer
8996 accepted in TestSuite.addTest(). This should cause no
8997 incompatibility since it never made sense with ordinary subclasses
8998 -- the failure just occurred later, with a more cumbersome
8999 exception.

9277 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009278
Georg Brandl3ee81df2008-05-17 18:14:43 +00009279- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009280 that the SMTP.starttls() caller no longer needs to call ehlo()
9281 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009282 does not claim to support starttls. Adds the
9283 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9364 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9365 silently miscode subclasses of those types. Now, it raises a
9366 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009367

Georg Brandl3ee81df2008-05-17 18:14:43 +00009382 time so that opening a database previously created with the DB_DUP
9383 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9384 opens. Specifically: dictionary assignment to a DB object will
9385 replace all values for a given key when the database allows
9386 duplicate values. DB users should use DB.put(k, v) when they want
9387 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009388

Georg Brandl3ee81df2008-05-17 18:14:43 +00009732- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9733 to ``PyTuple_SetItem``, it can be used to populate a brand new

9748 of w# format code incorrectly truncated the length to an int, even
9749 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9750 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009751

Georg Brandl3ee81df2008-05-17 18:14:43 +00009780- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9781 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009806- Removed the macfs module. It had been deprecated since Python 2.5.
9807 This lead to the deprecation of macostools.touched() as it relied
9808 solely on macfs and was a no-op under OS X.
