1260 In particular, fix extension module build failures when trying to use
1261 32-bit-only installer Pythons on systems with Xcode 4 (currently
1262 OS X 10.8, 10.7, and optionally 10.6).
1263 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1264 * Since Xcode 4 removes ppc support, extension module builds now
1265 check for ppc compiler support and by default remove ppc and
1266 ppc64 archs when they are not available.
1267 * Extension module builds now revert to using system installed
1268 headers and libs (/usr and /System/Library) if the SDK used
1269 to build the interpreter is not installed or has moved.
1270 * Try to avoid building extension modules with deprecated
1271 and problematic Apple llvm-gcc compiler. If original compiler
1272 is not available, use clang instead by default.

1704 Distutils-based packages with C extension modules may fail because
1705 Apple has removed gcc-4.2, the version used to build python.org
1706 64-bit/32-bit Pythons. If the user does not explicitly override
1707 the default C compiler by setting the CC environment variable,
1708 Distutils will now attempt to compile extension modules with clang
1709 if gcc-4.2 is required but not found. Also as a convenience, if
1710 the user does explicitly set CC, substitute its value as the default
1711 compiler in the Distutils LDSHARED configuration variable for OS X.
1712 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1713 SDK, neither of which are available in Xcode 4. This change does not
1714 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001964- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1965 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1966 interpreter process. This could cause failures in non-Distutils subprocesses
1967 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001968 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001969 deployment target only in the environment of each build subprocess. It is
1970 still possible to globally override the default by setting
1971 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1972 greater or equal to the default value, the value with which the interpreter
1973 was built.

2003 the ticker doesn't have to wind down to zero from the old starting point
2004 before the new interval takes effect. And if the user increases the
2005 interval, it makes sure the new limit takes effect right away rather have an
2006 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002986- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2987 This prevents user-created self-referencing ordered dictionaries from
2988 becoming permanently uncollectable GC garbage. The downside is that
2989 removing __del__ means that the internal doubly-linked list has to wait for
2990 GC collection rather than freeing memory immediately when the refcnt drops
2991 to zero.
2992
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002993- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

2999 to fetch the original errno, or to filter timeout errors. Now the
3000 original error is re-raised.

3004 be updated back after the system call. Original patch by Brian Brazil.

3021
R. David Murray7c4bf552010-08-25 01:45:57 +00003022- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3023 character years even if the message contains RFC822 two character years.
3024
Daniel Stutzbach91287322010-08-24 21:09:30 +00003025- Issue #8750: Fixed MutableSet's methods to correctly handle

3038
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003039- Issue #9617: Signals received during a low-level write operation aren't
3040 ignored by the buffered IO layer anymore.
3041
Benjamin Peterson52c36052010-08-21 03:03:22 +00003042- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

3044
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003045- Issue #9626: the view methods for collections.OrderedDict() were returning

3055 case in Python 2.5 and earlier).
3056
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003057- Issue #9550: a BufferedReader could issue an additional read when the
3058 original read request had been satisfied, which could block indefinitely
3059 when the underlying raw IO channel was e.g. a socket. Report and original
3060 patch by Jason V. Miller.
3061
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003062- Issue #9551: Don't raise TypeError when setting the value to None for

3090 the option character for the added 'h/help' option if prefix_chars
3091 does not contain a '-', instead of raising an error.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003450- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3451 start byte and the continuation byte(s) are now considered invalid, instead
3452 of the number of bytes specified by the start byte.
3453 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3454 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

3465 objects. (1) The comparison could incorrectly return True in some cases
3466 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003836- Issue #7301: Add environment variable $PYTHONWARNINGS.
3837
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003838- Issue #8329: Don't return the same lists from select.select when no fds are
3839 changed.
3840
Georg Brandlfee0f442010-05-22 21:26:21 +00003841- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003842 on 64-bit machines. The shift count for either left or right shift is
3843 permitted to be up to sys.maxsize.
3844
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003845- Ensure that tokenization of identifiers is not affected by locale.

3850
Georg Brandlfee0f442010-05-22 21:26:21 +00003851- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3852 with a non-empty format string. This is an effort to future-proof user
3853 code. If a derived class does not currently implement __format__ but later
3854 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003855 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003856 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003889- Issue #8257: The Decimal construct now accepts a float instance directly,
3890 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003891

3894
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003895- collections.Counter() now supports a subtract() method.
3896
Georg Brandlfee0f442010-05-22 21:26:21 +00003897- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00003906- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3907 InvalidOperation instead of returning False. (Comparisons involving a quiet
3908 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3909 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003910
Georg Brandlfee0f442010-05-22 21:26:21 +00003911- Issue #2531: Comparison operations between floats and Decimal instances now
3912 return a result based on the numeric values of the operands; previously they
3913 returned an arbitrary result based on the relative ordering of id(float) and
3914 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003915
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003916- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003917 argument `-` which tells it to read files to compile from stdin. Each line is
3918 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna58b65662010-03-30 16:29:03 +00003924- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3925 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003926 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00003928- Comparisons using one of <, <=, >, >= between a complex instance and a
3929 Fractions instance now raise TypeError instead of returning True/False. This
3930 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3931 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004288- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4289 and add the additional members returned in an OSVERSIONINFOEX structure. The
4290 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00004293- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4294 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4295 returning NULL. The macro now returns a statically allocated empty string
4296 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004342 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Georg Brandlba83f822010-03-14 09:50:54 +00004349 file position when calling `truncate()`. It would previously change the file
4350 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004351 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4352

4354 class used to represent files stored inside an archive. The new
4355 implementation is significantly faster and can be wrapped in a
4356 ``io.BufferedReader`` object for more speedups. It also solves an issue
4357 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004368- Issue #7748: Since unicode values are supported for some metadata options in
4369 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4370 encoded string for them. This ensures that the upload and register commands
4371 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004448- The ``__complex__()`` method is now looked up on the class of instances to
4449 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004451- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4452 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4453
Mark Dickinson1b34d252010-01-01 17:27:30 +00004454- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004455 DeprecationWarning when passed a float argument where an integer was expected.
4456 These functions and methods now raise TypeError instead. The majority of the
4457 effects of this change are in the extension modules, but some core functions
4458 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4459 and many unicode/str methods.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00004469- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
4470 used to drop the time part of the result.
4471
Georg Brandlba83f822010-03-14 09:50:54 +00004472- Issue #1811: Improve accuracy and cross-platform consistency for true division
4473 of integers: the result of a/b is now correctly rounded for ints a and b (at
4474 least on IEEE 754 platforms), and in particular does not depend on the
4475 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004477- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4478 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4479 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00004482 executables on OSX.
4483
Georg Brandlba83f822010-03-14 09:50:54 +00004484 These executables now work properly with the arch(1) command: ``arch -ppc
4485 python`` will start a universal binary version of python in PPC mode (unlike
4486 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00004487

Antoine Pitrou80157252010-01-08 19:20:17 +00004508- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00004509 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00004642- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4643 decimal string that's guaranteed to round back to x under correct rounding
4644 (with round-half-to-even rounding mode). Previously it gave a string based on
4645 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4646 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4647 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004648
Georg Brandlba83f822010-03-14 09:50:54 +00004649- Issue #7117: On almost all platforms: float-to-string and string-to-float
4650 conversions within Python are now correctly rounded. Places these conversions
4651 occur include: str for floats and complex numbers; the float and complex
4652 constructors; old-style and new-style numeric formatting; serialization and
4653 deserialization of floats and complex numbers using marshal, pickle and json;
4654 parsing of float and imaginary literals in Python code; Decimal-to-float
4655 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004656
Georg Brandlba83f822010-03-14 09:50:54 +00004657 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4658 providing correctly-rounded strtod and dtoa C functions. This code is
4659 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4660 the C compiler. There may be a small number of platforms on which correct
4661 operation of this code cannot be guaranteed, so the code is not used: notably,
4662 this applies to platforms where the C double format is not IEEE 754 binary64,
4663 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4664 and Python's configure script is unable to determine how to change the FPU
4665 precision. On these platforms conversions use the platform strtod and dtoa,
4666 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004668- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4669 uses the correctly-rounded string <-> float conversions described above (when
4670 available), and so produces correctly rounded results that will display nicely
4671 under the float repr. There are two related small changes: (1) round now
4672 accepts any class with an ``__index__()`` method for its second argument (but
4673 no longer accepts floats for the second argument), and (2) an excessively
4674 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4675 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004679- Fix several issues with ``compile()``. The input can now contain Windows and

5054 this code path is really executed because I cannot move to such directory on

5081 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006461- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6462 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6463 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6464 ``printf`` function, whereas PyString_FromFormat has an independent
6465 implementation and uses "%zd" on all platforms for size_t values.
6466 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +00006487 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00006562 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6563 for catch_warnings() also led to an improvement in the raising of a
6564 DeprecationWarning related to warnings.warn_explicit().
6565
Benjamin Peterson973e6c22008-09-01 23:12:58 +00006566- The deprecation warnings for the old camelCase threading API were removed.

6588
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006589- Issue #2975: When compiling several extension modules with Visual Studio 2008
6590 from the same python interpreter, some environment variables would grow
6591 without limit.
6592
Benjamin Peterson37346b22008-08-23 20:27:43 +00006593- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006630What's New in Python 2.6 beta 3?
6631================================
6632
Barry Warsaw07a4a382008-08-21 01:15:08 +00006633*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006634
6635Core and Builtins
6636-----------------
6637
Guido van Rossumf8402962008-08-20 15:01:50 +00006638- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6639 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6640 extensions do not automatically benefit from the class attribute
6641 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6642 to their tp_flags field if they care. This is a backwards
6643 compatibility feature; in 3.0, all types will use the cache by
6644 default.
6645
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006646- Keyword arguments can now follow starred arguments. (``f(a, *args,
6647 keyword=23)`` is now valid syntax.)
6648
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006649- ctypes function pointers that are COM methods have a boolean True
6650 value again.
6651
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006652- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6653 by denying s# to parse objects that have a releasebuffer procedure,
6654 and introducing s*.
6655
Georg Brandl1e13ea92008-08-11 09:07:59 +00006656- Issue #3537: Fix an assertion failure when an empty but presized dict
6657 object was stored in the freelist.
6658
Mark Dickinsonb6467572008-08-04 21:30:09 +00006659- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6660 ValueError consistently across platforms.
6661
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006662- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6663 (64bit Unix, for example), unichr() would truncate its argument and return
6664 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6665
Neal Norwitze7d8be82008-07-31 17:17:14 +00006666- Apply security patches from Apple.
6667
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006668- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6669 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6670
Antoine Pitrou92f82162008-07-25 22:22:08 +00006671- Issue #1819: function calls with several named parameters are now on
6672 average 35% faster (as measured by pybench).
6673
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006674- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6675 the python debugger steps into a class statement: the free variables (local
6676 variables defined in an outer scope) would be deleted from the outer scope.
6677
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006678- Issue #2620: Overflow checking when allocating or reallocating memory
6679 was not always being done properly in some python types and extension
6680 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6681 all been updated to perform better checks and places in the code that
6682 would previously leak memory on the error path when such an allocation
6683 failed have been fixed.
6684
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006685Library
6686-------
6687
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006688- Issue #3612: Added some missing basic types in ctypes.wintypes.
6689
Benjamin Petersone977ad42008-08-20 01:42:01 +00006690- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6691 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6692
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006693- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6694 version reported by these tools does not necessarily follow the python
6695 version numbering scheme, so the module is less strict when parsing it.
6696
Nick Coghlanf70385a2008-08-18 12:42:46 +00006697- Issue #2235: Added Py3k warnings for types which will become unhashable
6698 under the stricter __hash__ inheritance rules in 3.0. Several types
6699 which did not meet the rules for hash invariants and were already
6700 unhashable in 3.0 have now been explicitly flagged as unhashable in
6701 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6702 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6703
Brett Cannon88f801d2008-08-18 00:46:22 +00006704- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6705 imported into the module but exposed as part of the module's API.
6706
Brett Cannon7b96f072008-08-18 00:41:11 +00006707- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6708
Brett Cannon46225e72008-08-18 00:36:52 +00006709- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006711- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6712
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006713- Issue #3575: Incremental decoder's decode function now takes bytearray
6714 by using 's*' instead of 't#'.
6715
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006716- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006717 fails unicode conversion on 2nd parameter. (windows only)
6718
Georg Brandl222e2082010-08-01 22:27:39 +00006719- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006720 in a redirect.
6721
Brett Cannonabe423e2008-08-16 21:47:07 +00006722- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006723 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006724
Facundo Batistaeb90b782008-08-16 14:44:07 +00006725- Issue #2776: fixed small issue when handling an URL with double slash
6726 after a 302 response in the case of not going through a proxy.
6727
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006728- Issue #2676: in the email package, content-type parsing was hanging on
6729 pathological input because of quadratic or exponential behaviour of a
6730 regular expression.
6731
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006732- Issue #3476: binary buffered reading through the new "io" library is now
6733 thread-safe.
6734
Brett Cannonbf3157b2008-08-14 05:00:03 +00006735- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6736 since mimetools itself is deprecated. Because modules are cached, all
6737 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6738
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006739- Issue #3134: shutil referenced undefined WindowsError symbol.
6740
Robert Schuppenies14646332008-08-10 11:01:53 +00006741- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6742 menu entries were not deleted.
6743
Brett Cannon83e81842008-08-09 23:30:55 +00006744- Copied the implementation of reduce() to _functools.reduce() to have a
6745 version that did not raise a DeprecationWarning under -3.
6746
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006747- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6748 a MemoryError rather than silently stop the iteration.
6749
Guido van Rossum59ce9012008-08-09 14:55:34 +00006750- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6751 to _sre.compile() will now be rejected. This should not affect anybody
6752 since the re.compile() function never generates invalid re-bytecode.
6753
Skip Montanaroa032bf42008-08-08 22:52:51 +00006754- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6755 upon first access it can be automatically initialized from the csv file if
6756 it wasn't initialized during instantiation.
6757
Brett Cannon3aa2a492008-08-06 22:28:09 +00006758- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6759 the reload() built-in has been removed.
6760
Brett Cannon7e30b672008-08-04 21:52:25 +00006761- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006762 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006773 asking for a specific length. This problem only affected files opened
6774 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006775

6800 file name rather than a ZipInfo instance, so files are extracted with
6801 mode 0600 rather than 000 under Unix.
6802

6820 regarding lack of coverage of new-style classes have also been
6821 removed, since the coverage is now fairly reasonable.

Georg Brandl3e483f62008-07-16 22:57:41 +00006832- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6833 its methods now allow for items objects that can be converted to
6834 an integer using operator.index().
6835
Mark Dickinson64b7e502008-07-16 09:40:03 +00006836- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6837 produced a ValueError instead of giving the correct float.
6838
Eric Smitha5fa5a22008-07-16 00:11:49 +00006839- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6840 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6841
Mark Dickinson7103aa42008-07-15 19:08:33 +00006842- Issue #3008: the float type has a new instance method 'float.hex'
6843 and a new class method 'float.fromhex' to convert floating-point
6844 numbers to and from hexadecimal strings, respectively.
6845
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006846- Issue #2235: __hash__ is once again inherited by default. To allow
6847 collections.Hashable to remain meaningful in the presence of the
6848 default hash implementation (object.__hash__), it is now possible
6849 to explicit block inheritance of hash by setting __hash__=None at
6850 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6851 level.
6852
Nick Coghlanb028f502008-07-13 14:52:36 +00006853- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6854 the parent module cannot be found while performing an absolute import.
6855 This means that an incorrectly defined __package__ attribute will
6856 now only prevent relative imports in that module rather than causing
6857 all imports from that module to fail.
6858
Nick Coghlan14ff9942008-07-08 14:21:42 +00006859- Issue #2517: Allow unicode messages in Exceptions again by correctly

6869 another thread's dictionary.
6870
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006871- Issue #3004: Minor change to slice.indices(): the start and stop
6872 arguments are now treated identically, making the behaviour easier
6873 to describe and understand. For example, slice(None, -10,
6874 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6875 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6876 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00006878- Issue #3219: Calling a function with repeated keyword arguments,
6879 f(a=2, a=23), would not cause a syntax error. This was a regression
6880 from 2.4 caused by the switch to the new compiler.

6919 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006920 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007392- Issue #1631171: Re-implement the 'warnings' module in C (the
7393 original Python code has been kept as backup). This will allow for
7394 using the 'warning's machinery in such places as the parser where
7395 use of pure Python code is not possible. Both the ``showarning()``
7396 and ``formatwarning()`` gain an optional 'line' argument which is
7397 not called by default for backwards-compatibility reasons. Setting
7398 ``warnings.showwarning()`` to an implementation that lacks support
7399 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007462- Issue #2550: The approach used by client/server code for obtaining
7463 ports to listen on in network-oriented tests has been refined in an
7464 effort to facilitate running multiple instances of the entire
7465 regression test suite in parallel without issue.
7466 test_support.bind_port() has been fixed such that it will always
7467 return a unique port -- which wasn't always the case with the
7468 previous implementation, especially if socket options had been set
7469 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7470 new implementation of bind_port() will actually raise an exception
7471 if it is passed an AF_INET/SOCK_STREAM socket with either the
7472 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7473 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7474 the socket it's been passed. This currently only applies to
7475 Windows. This option prevents any other sockets from binding to the
7476 host/port we've bound to, thus removing the possibility of the
7477 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7478 when a second SOCK_STREAM socket binds and accepts to a host/port
7479 that's already been bound by another socket. The optional preferred
7480 port parameter to bind_port() has been removed. Under no
7481 circumstances should tests be hard coding ports!
7482
7483 test_support.find_unused_port() has also been introduced, which will
7484 pass a temporary socket object to bind_port() in order to obtain an
7485 unused port. The temporary socket object is then closed and
7486 deleted, and the port is returned. This method should only be used
7487 for obtaining an unused port in order to pass to an external program
7488 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7489 a parameter to a server-oriented class that doesn't give you direct
7490 access to the underlying socket used.
7491
7492 Finally, test_support.HOST has been introduced, which should be used
7493 for the host argument of any relevant socket calls (i.e. bind and
7494 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007495
7496 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007497 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007498 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7499 test_asynchat and test_socket_ssl.
7500
Georg Brandl3ee81df2008-05-17 18:14:43 +00007501 It is now possible for multiple instances of the regression test
7502 suite to run in parallel without issue.

7658 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00007659 platform.machine() and platform.processor() will report this
7660 information as well.

Facundo Batistafc2d0102008-02-23 12:01:13 +00007780
Eric Smitha73fbe72008-02-23 03:09:44 +00007781- Added the future_builtins module, which contains hex() and oct().
7782 These are the PEP 3127 version of these functions, designed to be
7783 compatible with the hex() and oct() builtins from Python 3.0. They
7784 differ slightly in their output formats from the existing, unchanged
7785 Python 2.6 builtins. The expected usage of the future_builtins
7786 module is:
7787 from future_builtins import hex, oct
7788
Eric Smith7ef40bf2008-02-20 23:34:22 +00007789- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7790 exponents for exponents with absolute value < 100. Follows C99
7791 standard. This is a change on Windows, which would use 3 digits.
7792 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7793 so that any alterations it does to the resulting string will be
7794 available in stringlib/formatter.h (for float.__format__).
7795
Eric Smith5a3c1352008-02-19 13:21:56 +00007796- Implemented PEP 3101, Advanced String Formatting. This adds a new
7797 builtin format(); a format() method for str and unicode; a
7798 __format__() method to object, str, unicode, int, long, float, and
7799 datetime; the class string.Formatter; and the C API
7800 PyObject_Format().
7801
Georg Brandl3ee81df2008-05-17 18:14:43 +00007802- Fixed several potential crashes, all caused by specially crafted
7803 __del__ methods exploiting objects in temporarily inconsistent
7804 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007805
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007806- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007807 prevent a possible crash: an Abstract Base Class would try to access
7808 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007809
Georg Brandl3ee81df2008-05-17 18:14:43 +00007810- Fixed repr() and str() of complex numbers with infinity or nan as

Georg Brandl3ee81df2008-05-17 18:14:43 +00007813- Clear all free lists during a gc.collect() of the highest generation
7814 in order to allow pymalloc to free more arenas. Python may give back
7815 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007816
Georg Brandl3ee81df2008-05-17 18:14:43 +00007817- Issue #2045: Fix an infinite recursion triggered when printing a
7818 subclass of collections.defaultdict, if its default_factory is set
7819 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007820
Christian Heimesf75dbef2008-02-08 00:11:31 +00007821- Fixed a minor memory leak in dictobject.c. The content of the free
7822 list was not freed on interpreter shutdown.
7823
Georg Brandl21e99f42010-03-07 15:23:59 +00007824- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007825 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007826
Georg Brandl3ee81df2008-05-17 18:14:43 +00007827- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7828 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007829 to compact the internal free lists of pre-allocted ints and floats.
7830
Georg Brandl3ee81df2008-05-17 18:14:43 +00007831- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7832 calls. Python expected the return type int but the fork familie
7833 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007834
Georg Brandl3ee81df2008-05-17 18:14:43 +00007835- Issue #1678380: Fix a bug that identifies 0j and -0j when they

7845 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007846
Georg Brandl3ee81df2008-05-17 18:14:43 +00007847- Patch #1473257: generator objects gain a gi_code attribute. This is
7848 the same object as the func_code attribute of the function that
7849 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007850
Georg Brandl3ee81df2008-05-17 18:14:43 +00007851- Issue #1920: "while 0" statements were completely removed by the
7852 compiler, even in the presence of an "else" clause, which is
7853 supposed to be run when the condition is false. Now the compiler
7854 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007855
Guido van Rossumeead05f2008-01-24 18:21:02 +00007856- A few crashers fixed: weakref_in_del.py (issue #1377858);
7857 loosing_dict_ref.py (issue #1303614, test67.py);
7858 borrowed_ref_[34].py (not in tracker).
7859
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007860- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007861 suppressed while an extension is loaded by calling SetErrorMode in
7862 dynload_win.c. The error is still reported properly.
7863
Georg Brandl3ee81df2008-05-17 18:14:43 +00007864- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007865 several extension methods and modules do not work without unicode
7866 support.
7867
Georg Brandl26543b12008-01-21 18:36:51 +00007868- Issue #1882: when compiling code from a string, encoding cookies in the
7869 second line of code were not always recognized correctly.
7870
Georg Brandl14404b62008-01-19 19:27:05 +00007871- Issue #1679: "0x" was taken as a valid integer literal.
7872
Georg Brandl6caad7d2008-01-26 14:19:22 +00007873- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007874 added.
7875
Christian Heimesc94e2b52008-01-14 04:13:37 +00007876- sys.float_info / PyFloat_GetInfo: The floating point information
7877 object was converted from a dict to a specialized structseq object.
7878
Georg Brandl3ee81df2008-05-17 18:14:43 +00007879- Patch #1816: Added sys.flags structseq. It exposes the status of
7880 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007881
Georg Brandl3ee81df2008-05-17 18:14:43 +00007882- Objects/structseq.c: Implemented new structseq representation. The
7883 patch makes structseqs (e.g. the return value of os.stat) more
7884 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007885
Georg Brandl3ee81df2008-05-17 18:14:43 +00007886- Patch #1700288: added a type attribute cache that caches method

7895 envvar and sys.dont_write_bytecode attribute. All these can be set
7896 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007897
Georg Brandl3ee81df2008-05-17 18:14:43 +00007898- Improve some exception messages when Windows fails to load an
7899 extension module. Now we get for example '%1 is not a valid Win32

7912 literals. The oparg for BUILD_MAP now indicates an estimated
7913 dictionary size. There is a new opcode, STORE_MAP, for adding
7914 entries to the dictionary.

7957
Georg Brandl21e99f42010-03-07 15:23:59 +00007958- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007959 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7960 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007961
Georg Brandl3ee81df2008-05-17 18:14:43 +00007962- Issue #1686386: Tuple's tp_repr did not take into account the
7963 possibility of having a self-referential tuple, which is possible
7964 from C code. Nor did object's tp_str consider that a type's tp_str
7965 could do something that could lead to an inifinite recursion.
7966 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7967 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007968
Georg Brandl3ee81df2008-05-17 18:14:43 +00007969- Issue #1164: It was possible to trigger deadlock when using the
7970 'print' statement to write to a file since the GIL was not released
7971 as needed. Now PyObject_Print() does the right thing along with
7972 various tp_print implementations of the built-in types and those in
7973 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00007982- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007983 PyObject_Call() never calling back out to Python code to trigger
7984 recursion depth updates/checks. Required the creation of a static
7985 RuntimeError instance in case normalizing an exception put the
7986 recursion check value past its limit. Fixes crashers
7987 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00008002- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008003 __*__ attributes. (Some already existed, e.g., __doc__ and
8004 __name__.)

8010 calls.
8011
Collin Winter62903052007-05-18 23:11:24 +00008012- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008013 "except E as target:". This is to provide forwards compatibility
8014 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008021- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008022 setting a plain string, ie don't expand to single letter identifiers.
8023
Raymond Hettinger13936692007-04-11 18:40:58 +00008024- Request #1191699: Slices can now be pickled.
8025
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008026- Request #1193128: str.translate() now allows a None argument for
8027 translations that only remove characters without re-mapping the
8028 remaining characters.
8029
Georg Brandl5cb76c12007-03-21 09:00:39 +00008030- Patch #1682205: a TypeError while unpacking an iterable is no longer

8034
Guido van Rossum143b5642007-03-23 04:58:42 +00008035- Bug #1683368: The object.__init__() and object.__new__() methods are
8036 now stricter in rejecting excess arguments. The only time when
8037 either allows excess arguments is when it is not overridden and the
8038 other one is. For backwards compatibility, when both are
8039 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008040 warning later). Also, type.__init__() insists on the same signature
8041 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008042
Georg Brandl3ee81df2008-05-17 18:14:43 +00008043- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8044 object to complex using its __complex__() method before falling back
8045 to the __float__() method. Therefore, the functions in the cmath
8046 module now can operate on objects that define a __complex__()
8047 method.

8058 its type.

8064
Georg Brandl7b9c5552007-03-12 14:30:05 +00008065- Bug #1678647: write a newline after printing an exception in any
8066 case, even when converting the value to a string failed.
8067
Georg Brandl871f1bc2007-03-12 13:17:36 +00008068- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008069 its argument, if it exists. If not, it will work like before. This
8070 allows customizing the output of dir() in the presence of a
8071 __getattr__().

8080 parthensized forms. This means complex(repr(x)) now works instead of
8081 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008082
Georg Brandlaa2321b2007-03-07 00:40:28 +00008083- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008084 makes the filenames the warning module prints much more sensible
8085 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008098- Patch #1674228: when assigning a slice (old-style), check for the
8099 sq_ass_slice instead of the sq_slice slot.
8100
Georg Brandl3ee81df2008-05-17 18:14:43 +00008101- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00008636 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00008638

8653
Georg Brandl3ee81df2008-05-17 18:14:43 +00008654- Patch #1530482: add pydoc.render_doc() which returns the

8669
Georg Brandl92a6bae2007-03-13 17:43:32 +00008670- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008671 are set for invalid interpolation sequences that would lead to
8672 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008673

8726
Georg Brandl3ee81df2008-05-17 18:14:43 +00008727- unittest now verifies more of its assumptions. In particular,
8728 TestCase and TestSuite subclasses (not instances) are no longer
8729 accepted in TestSuite.addTest(). This should cause no
8730 incompatibility since it never made sense with ordinary subclasses
8731 -- the failure just occurred later, with a more cumbersome
8732 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009013 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00009015 does not claim to support starttls. Adds the
9016 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009114- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009115 time so that opening a database previously created with the DB_DUP
9116 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9117 opens. Specifically: dictionary assignment to a DB object will
9118 replace all values for a given key when the database allows
9119 duplicate values. DB users should use DB.put(k, v) when they want
9120 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00009408- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00009409 periodic threadstate and signal checking in tight loops. By
9410 default, this option is turned-off. It should only be enabled in
9411 debugged, performance critical applications.

9462-----
9463
Georg Brandl3ee81df2008-05-17 18:14:43 +00009464- Unified naming convention for free lists and their limits. All free
9465 lists in Object/ are named ``free_list``, the counter ``numfree``
9466 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
9467 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00009468
Georg Brandl3ee81df2008-05-17 18:14:43 +00009469- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
9470 to ``PyTuple_SetItem``, it can be used to populate a brand new
9471 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00009472

9483
Georg Brandl3ee81df2008-05-17 18:14:43 +00009484- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9485 of w# format code incorrectly truncated the length to an int, even
9486 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9487 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009488
Georg Brandl3ee81df2008-05-17 18:14:43 +00009489- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

9509
9510- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9511 outside of pystate.c and should not be necessary.
9512
Georg Brandl3ee81df2008-05-17 18:14:43 +00009513- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
9514 absolute imports. In earlier versions they might have used relative
9515 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009516
Georg Brandl3ee81df2008-05-17 18:14:43 +00009517- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9518 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009519
Georg Brandl3ee81df2008-05-17 18:14:43 +00009520- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009545- Removed the macfs module. It had been deprecated since Python 2.5.
9546 This lead to the deprecation of macostools.touched() as it relied
