25 an existing .py counterpart, override the co_filename attributes of all
26 code objects if the original filename is obsolete (which can happen if the
27 file has been renamed, moved, or if it is accessed through different paths).
28 Patch by Ziga Seilnacht and Jean-Paul Calderone.

64
Vinay Sajip6badbe92009-01-20 22:49:13 +000065- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +000066 method on file objects with closefd=False. The file descriptor is still

82 inside its source path if it began with the same letters (e.g. "src" vs.
83 "src.new").
84
Raymond Hettingerc9794482009-01-28 23:14:58 +000085- Issue 4920: Fixed .next() vs .__next__() issues in the ABCs for

98 do an explicit seek to the end of file (so that e.g. tell() returns the

100 traditional 2.x file object.
101
Amaury Forgeot d'Arc0293c802009-01-17 16:46:35 +0000102- Issue #3997: zipfiles generated with more than 65536 files could not be
103 opened with other applications.
104
Raymond Hettinger825758c2009-01-08 05:20:19 +0000105- Issue 4816: itertools.combinations() and itertools.product were raising

113 did unnecessary work in the common case where no key function was specified.

133
134- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
135 302 conformant loader) will now work correctly in most cases (they
136 are still subject to the constraints that exist for all code running
137 from inside a module loaded via a PEP 302 loader and attempting to
138 perform IO operations based on __file__). Original patch by
139 Alexander Belopolsky.

458
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000459- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
460 PyString_FromFormat or PyErr_Format to display size_t values. The macro
461 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
462 ``printf`` function, whereas PyString_FromFormat has an independent
463 implementation and uses "%zd" on all platforms for size_t values.
464 This makes a difference on win64, where ``printf`` needs "%Id" to display
465 64bit values.

483
Vinay Sajip35e3b032008-09-01 14:33:59 +0000484- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000485 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
486 mechanism. In the process, fix a bug where isinstance() and issubclass(),
487 when given a tuple of classes as second argument, were looking up
488 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
489 type object.

630Core and Builtins
631-----------------
632
Guido van Rossumf8402962008-08-20 15:01:50 +0000633- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
634 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
635 extensions do not automatically benefit from the class attribute
636 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
637 to their tp_flags field if they care. This is a backwards
638 compatibility feature; in 3.0, all types will use the cache by
639 default.
640
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000641- Keyword arguments can now follow starred arguments. (``f(a, *args,
642 keyword=23)`` is now valid syntax.)
643
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000644- ctypes function pointers that are COM methods have a boolean True
645 value again.
646
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000647- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
648 by denying s# to parse objects that have a releasebuffer procedure,
649 and introducing s*.
650
Georg Brandl1e13ea92008-08-11 09:07:59 +0000651- Issue #3537: Fix an assertion failure when an empty but presized dict
652 object was stored in the freelist.
653
Mark Dickinsonb6467572008-08-04 21:30:09 +0000654- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
655 ValueError consistently across platforms.
656
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000657- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
658 (64bit Unix, for example), unichr() would truncate its argument and return
659 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
660
Neal Norwitze7d8be82008-07-31 17:17:14 +0000661- Apply security patches from Apple.
662
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000663- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
664 PyErr_ExceptionMatches returns 0 when an exception occurs there.
665
Antoine Pitrou92f82162008-07-25 22:22:08 +0000666- Issue #1819: function calls with several named parameters are now on
667 average 35% faster (as measured by pybench).
668
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000669- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
670 the python debugger steps into a class statement: the free variables (local
671 variables defined in an outer scope) would be deleted from the outer scope.
672
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000673- Issue #2620: Overflow checking when allocating or reallocating memory
674 was not always being done properly in some python types and extension
675 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
676 all been updated to perform better checks and places in the code that
677 would previously leak memory on the error path when such an allocation
678 failed have been fixed.
679

681-------
682
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +0000683- Issue #3612: Added some missing basic types in ctypes.wintypes.
684
Benjamin Petersone977ad42008-08-20 01:42:01 +0000685- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
686 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
687
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000688- Issue #2234: distutils failed for some versions of the cygwin compiler. The
689 version reported by these tools does not necessarily follow the python
690 version numbering scheme, so the module is less strict when parsing it.
691
Nick Coghlanf70385a2008-08-18 12:42:46 +0000692- Issue #2235: Added Py3k warnings for types which will become unhashable
693 under the stricter __hash__ inheritance rules in 3.0. Several types
694 which did not meet the rules for hash invariants and were already
695 unhashable in 3.0 have now been explicitly flagged as unhashable in
696 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
697 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
698
Brett Cannon88f801d2008-08-18 00:46:22 +0000699- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
700 imported into the module but exposed as part of the module's API.
701
Brett Cannon7b96f072008-08-18 00:41:11 +0000702- Remove an unneeded import of abc.ABCMeta from 'inspect'.
703
Brett Cannon46225e72008-08-18 00:36:52 +0000704- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
705
Brett Cannon25c9d6a2008-08-17 22:10:11 +0000706- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
707
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000708- Issue #3575: Incremental decoder's decode function now takes bytearray
709 by using 's*' instead of 't#'.
710
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000711- Issue #2222: Fixed reference leak when occured os.rename()
712 fails unicode conversion on 2nd parameter. (windows only)
713
Facundo Batista94f243a2008-08-17 03:38:39 +0000714- Issue 2464. urllib2 now supports a malformation in the URL received
715 in a redirect.
716
Brett Cannonabe423e2008-08-16 21:47:07 +0000717- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000718 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000719
Facundo Batistaeb90b782008-08-16 14:44:07 +0000720- Issue #2776: fixed small issue when handling an URL with double slash
721 after a 302 response in the case of not going through a proxy.
722
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000723- Issue #2676: in the email package, content-type parsing was hanging on
724 pathological input because of quadratic or exponential behaviour of a
725 regular expression.
726
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000727- Issue #3476: binary buffered reading through the new "io" library is now
728 thread-safe.
729
Brett Cannonbf3157b2008-08-14 05:00:03 +0000730- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
731 since mimetools itself is deprecated. Because modules are cached, all
732 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
733
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000734- Issue #3134: shutil referenced undefined WindowsError symbol.
735
Robert Schuppenies14646332008-08-10 11:01:53 +0000736- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
737 menu entries were not deleted.
738
Brett Cannon83e81842008-08-09 23:30:55 +0000739- Copied the implementation of reduce() to _functools.reduce() to have a
740 version that did not raise a DeprecationWarning under -3.
741
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000742- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
743 a MemoryError rather than silently stop the iteration.
744
Guido van Rossum59ce9012008-08-09 14:55:34 +0000745- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
746 to _sre.compile() will now be rejected. This should not affect anybody
747 since the re.compile() function never generates invalid re-bytecode.
748
Skip Montanaroa032bf42008-08-08 22:52:51 +0000749- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
750 upon first access it can be automatically initialized from the csv file if
751 it wasn't initialized during instantiation.
752
Brett Cannon3aa2a492008-08-06 22:28:09 +0000753- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
754 the reload() built-in has been removed.
755
Brett Cannon7e30b672008-08-04 21:52:25 +0000756- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000757 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +0000758 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
759 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
760 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
761 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
762 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +0000763
Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000764- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
765 raised an AttributeError.
766
Benjamin Peterson01a24322008-07-28 23:35:27 +0000767- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000768 asking for a specific length. This problem only affected files opened
769 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000770
Mark Dickinsonfe84cce2008-07-27 06:39:07 +0000771- Issue #3449: Update decimal module to use most recent specification
772 (v. 1.68) and tests (v. 2.58) from IBM.
773
Skip Montanarof9ac43f2008-07-27 00:50:41 +0000774- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
775
Raymond Hettinger8c664e82008-07-25 18:43:33 +0000776- Issue 1592: Improve error reporting when operations are attempted
777 on a closed shelf.
778
Georg Brandlf9efabb2008-07-23 15:16:45 +0000779- Deprecate the "ast" parser function aliases.
780
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000781- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
782
783- Issue #3303: Fix a crash in locale.strcoll() when calling it with
784 invalid arguments.
785
786- Issue #3302: Fix several crashes when calling locale's gettext functions
787 with None arguments.
788
789- Issue #3389: Allow resolving dotted names for handlers in logging
790 configuration files.
791
792- Deprecate the sunaudio module for removal in Python 3.0.
793
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000794- Issue #3394: zipfile.writestr sets external attributes when passed a
795 file name rather than a ZipInfo instance, so files are extracted with
796 mode 0600 rather than 000 under Unix.
797
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000798- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
799 argument in python 2.5, this broke code that subclassed Popen to include its
800 own poll method. Fixed my moving _deadstate to an _internal_poll method.
801
Martin v. Löwis8dbf3642008-08-01 14:10:26 +0000802Build
803-----

808-------------
809
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000810- Issue #2235: the C API function PyObject_HashNotImplemented and its
811 interaction with the tp_hash slot (added in 2.6b2) are now documented
812
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000813- Issue #643841: The language reference now provides more detailed
814 coverage of the lookup process for special methods. The disclaimers
815 regarding lack of coverage of new-style classes have also been
816 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000822*Release date: 17-Jul-2008*
823
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000824Core and Builtins
825-----------------
826
Georg Brandl3e483f62008-07-16 22:57:41 +0000827- Issue #3156: Fix inconsistent behavior of the bytearray type: all
828 its methods now allow for items objects that can be converted to
829 an integer using operator.index().
830
Mark Dickinson64b7e502008-07-16 09:40:03 +0000831- Issue #3360: Fix incorrect parsing of '020000000000.0', which
832 produced a ValueError instead of giving the correct float.
833
Eric Smitha5fa5a22008-07-16 00:11:49 +0000834- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
835 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
836
Mark Dickinson7103aa42008-07-15 19:08:33 +0000837- Issue #3008: the float type has a new instance method 'float.hex'
838 and a new class method 'float.fromhex' to convert floating-point
839 numbers to and from hexadecimal strings, respectively.
840
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000841- Issue #2235: __hash__ is once again inherited by default. To allow
842 collections.Hashable to remain meaningful in the presence of the
843 default hash implementation (object.__hash__), it is now possible
844 to explicit block inheritance of hash by setting __hash__=None at
845 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
846 level.
847
Nick Coghlanb028f502008-07-13 14:52:36 +0000848- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
849 the parent module cannot be found while performing an absolute import.
850 This means that an incorrectly defined __package__ attribute will
851 now only prevent relative imports in that module rather than causing
852 all imports from that module to fail.
853
Nick Coghlan14ff9942008-07-08 14:21:42 +0000854- Issue #2517: Allow unicode messages in Exceptions again by correctly
855 bypassing the instance dictionary when looking up __unicode__ on
856 new-style classes.
857
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000858- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
859 set to a custom object whose write() method happens to install
860 another file in sys.stdout.
861
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000862- Issue #3088: Corrected a race condition in classes derived from
863 threading.local: the first member set by a thread could be saved in
864 another thread's dictionary.
865
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000866- Issue #3004: Minor change to slice.indices(): the start and stop
867 arguments are now treated identically, making the behaviour easier
868 to describe and understand. For example, slice(None, -10,
869 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
870 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
871 10, -1).
872
Georg Brandl278fc502008-07-19 12:46:12 +0000873- Issue #3219: Calling a function with repeated keyword arguments,
874 f(a=2, a=23), would not cause a syntax error. This was a regression
875 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000876
Georg Brandl278fc502008-07-19 12:46:12 +0000877- Issue #2862: Make int and float freelist management consistent with
878 other freelists. Changes their CompactFreeList apis into
879 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +0000880

882-------
883
Thomas Heller57adf222008-08-14 19:10:48 +0000884- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
885 api functions without holding the GIL, which could lead to a fatal
886 error when they failed.
887
Martin v. Löwisaabf4042008-08-02 07:20:25 +0000888- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
889

897 ForkingPickler.register() to resolve conflict with ctypes.
898
Vinay Sajip51e65192008-07-18 09:01:10 +0000899- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +0000900
Thomas Heller880f5292008-07-15 19:39:38 +0000901- Issue #3313: Fixed a crash when a failed dlopen() call does not set
902 a valid dlerror() message.
903
Thomas Heller2bad6572008-07-15 17:19:50 +0000904- Issue #3258: Fixed a crash when a ctypes POINTER type to an
905 incomplete structure was created.
906
Brett Cannon3d0b9f02008-07-13 01:15:07 +0000907- Issue #3339: dummy_thread.acquire() should not return None.
908
Raymond Hettingerb01713e2008-07-10 14:34:57 +0000909- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
910
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +0000911- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +0000912
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +0000913- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
914 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +0000915 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +0000916 content-length. The problem had been corrected in the 2.4 branch, but never
917 merged into trunk.
918
Georg Brandle78fbcc2008-07-05 10:13:36 +0000919- Issue #2663: add filtering capability to shutil.copytree().
920

1324 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001325 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001326
1327 This is controlled by the configure argument ``--with-universal-archs``:
1328
1329 - ``--with-universal-archs=all``: install 4-way universal
1330
1331 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1332
1333 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1334
1335 This option should be used in combination with ``--enable-universalsdk=``.
1336
1337 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00001387- Issue #1631171: Re-implement the 'warnings' module in C (the
1388 original Python code has been kept as backup). This will allow for
1389 using the 'warning's machinery in such places as the parser where
1390 use of pure Python code is not possible. Both the ``showarning()``
1391 and ``formatwarning()`` gain an optional 'line' argument which is
1392 not called by default for backwards-compatibility reasons. Setting
1393 ``warnings.showwarning()`` to an implementation that lacks support
1394 for the ``line`` argument will raise a DeprecationWarning.

1418
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001419- The getpass module has been improved on Unix. It now uses /dev/tty
1420 by default and uses stderr instead of stdout. A GetPassWarning is
1421 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001457- Issue #2550: The approach used by client/server code for obtaining
1458 ports to listen on in network-oriented tests has been refined in an
1459 effort to facilitate running multiple instances of the entire
1460 regression test suite in parallel without issue.
1461 test_support.bind_port() has been fixed such that it will always
1462 return a unique port -- which wasn't always the case with the
1463 previous implementation, especially if socket options had been set
1464 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1465 new implementation of bind_port() will actually raise an exception
1466 if it is passed an AF_INET/SOCK_STREAM socket with either the
1467 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1468 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1469 the socket it's been passed. This currently only applies to
1470 Windows. This option prevents any other sockets from binding to the
1471 host/port we've bound to, thus removing the possibility of the
1472 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1473 when a second SOCK_STREAM socket binds and accepts to a host/port
1474 that's already been bound by another socket. The optional preferred
1475 port parameter to bind_port() has been removed. Under no
1476 circumstances should tests be hard coding ports!
1477
1478 test_support.find_unused_port() has also been introduced, which will
1479 pass a temporary socket object to bind_port() in order to obtain an
1480 unused port. The temporary socket object is then closed and
1481 deleted, and the port is returned. This method should only be used
1482 for obtaining an unused port in order to pass to an external program
1483 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1484 a parameter to a server-oriented class that doesn't give you direct
1485 access to the underlying socket used.
1486
1487 Finally, test_support.HOST has been introduced, which should be used
1488 for the host argument of any relevant socket calls (i.e. bind and
1489 connect).

1763Core and builtins
1764-----------------
1765
Fred Drakea8ee94b2008-03-01 02:45:07 +00001766- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001767 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001768
Georg Brandlad61bc82008-02-23 15:11:18 +00001769- Issue #2067: file.__exit__() now calls subclasses' close() method.
1770
1771- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001772
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001773- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001774 issue 215555 for a discussion.
1775
Eric Smitha73fbe72008-02-23 03:09:44 +00001776- Added the future_builtins module, which contains hex() and oct().
1777 These are the PEP 3127 version of these functions, designed to be
1778 compatible with the hex() and oct() builtins from Python 3.0. They
1779 differ slightly in their output formats from the existing, unchanged
1780 Python 2.6 builtins. The expected usage of the future_builtins
1781 module is:
1782 from future_builtins import hex, oct
1783
Eric Smith7ef40bf2008-02-20 23:34:22 +00001784- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1785 exponents for exponents with absolute value < 100. Follows C99
1786 standard. This is a change on Windows, which would use 3 digits.
1787 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1788 so that any alterations it does to the resulting string will be
1789 available in stringlib/formatter.h (for float.__format__).
1790
Eric Smith5a3c1352008-02-19 13:21:56 +00001791- Implemented PEP 3101, Advanced String Formatting. This adds a new
1792 builtin format(); a format() method for str and unicode; a
1793 __format__() method to object, str, unicode, int, long, float, and
1794 datetime; the class string.Formatter; and the C API
1795 PyObject_Format().
1796
Georg Brandl3ee81df2008-05-17 18:14:43 +00001797- Fixed several potential crashes, all caused by specially crafted
1798 __del__ methods exploiting objects in temporarily inconsistent
1799 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001800
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001801- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001802 prevent a possible crash: an Abstract Base Class would try to access
1803 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001804
Georg Brandl3ee81df2008-05-17 18:14:43 +00001805- Fixed repr() and str() of complex numbers with infinity or nan as
1806 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001807
Georg Brandl3ee81df2008-05-17 18:14:43 +00001808- Clear all free lists during a gc.collect() of the highest generation
1809 in order to allow pymalloc to free more arenas. Python may give back
1810 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001811
Georg Brandl3ee81df2008-05-17 18:14:43 +00001812- Issue #2045: Fix an infinite recursion triggered when printing a
1813 subclass of collections.defaultdict, if its default_factory is set
1814 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001815
Christian Heimesf75dbef2008-02-08 00:11:31 +00001816- Fixed a minor memory leak in dictobject.c. The content of the free
1817 list was not freed on interpreter shutdown.
1818
Georg Brandl3ee81df2008-05-17 18:14:43 +00001819- Limit free list of method and builtin function objects to 256
1820 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001821
Georg Brandl3ee81df2008-05-17 18:14:43 +00001822- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1823 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001824 to compact the internal free lists of pre-allocted ints and floats.
1825
Georg Brandl3ee81df2008-05-17 18:14:43 +00001826- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1827 calls. Python expected the return type int but the fork familie
1828 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001829
Georg Brandl3ee81df2008-05-17 18:14:43 +00001830- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1831 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001832
Georg Brandl3ee81df2008-05-17 18:14:43 +00001833- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1834 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001835
Georg Brandl3ee81df2008-05-17 18:14:43 +00001836- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
1837 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00001838
Georg Brandl3ee81df2008-05-17 18:14:43 +00001839- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1840 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001841
Georg Brandl3ee81df2008-05-17 18:14:43 +00001842- Patch #1473257: generator objects gain a gi_code attribute. This is
1843 the same object as the func_code attribute of the function that
1844 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001845
Georg Brandl3ee81df2008-05-17 18:14:43 +00001846- Issue #1920: "while 0" statements were completely removed by the
1847 compiler, even in the presence of an "else" clause, which is
1848 supposed to be run when the condition is false. Now the compiler
1849 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001850
Guido van Rossumeead05f2008-01-24 18:21:02 +00001851- A few crashers fixed: weakref_in_del.py (issue #1377858);
1852 loosing_dict_ref.py (issue #1303614, test67.py);
1853 borrowed_ref_[34].py (not in tracker).
1854
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001855- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001856 suppressed while an extension is loaded by calling SetErrorMode in
1857 dynload_win.c. The error is still reported properly.
1858
Georg Brandl3ee81df2008-05-17 18:14:43 +00001859- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001860 several extension methods and modules do not work without unicode
1861 support.
1862
Georg Brandl26543b12008-01-21 18:36:51 +00001863- Issue #1882: when compiling code from a string, encoding cookies in the
1864 second line of code were not always recognized correctly.
1865
Georg Brandl14404b62008-01-19 19:27:05 +00001866- Issue #1679: "0x" was taken as a valid integer literal.
1867
Georg Brandl6caad7d2008-01-26 14:19:22 +00001868- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001869 added.
1870
Christian Heimesc94e2b52008-01-14 04:13:37 +00001871- sys.float_info / PyFloat_GetInfo: The floating point information
1872 object was converted from a dict to a specialized structseq object.
1873
Georg Brandl3ee81df2008-05-17 18:14:43 +00001874- Patch #1816: Added sys.flags structseq. It exposes the status of
1875 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001876
Georg Brandl3ee81df2008-05-17 18:14:43 +00001877- Objects/structseq.c: Implemented new structseq representation. The
1878 patch makes structseqs (e.g. the return value of os.stat) more
1879 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001880
Georg Brandl3ee81df2008-05-17 18:14:43 +00001881- Patch #1700288: added a type attribute cache that caches method
1882 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00001883
Neal Norwitz3fc15b82008-01-10 05:42:58 +00001884- Bug #1776: __import__() no longer accepts filenames on any platform.
1885 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00001886
Georg Brandlaed6c662008-01-07 17:25:53 +00001887- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
1888
Georg Brandl3ee81df2008-05-17 18:14:43 +00001889- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
1890 envvar and sys.dont_write_bytecode attribute. All these can be set
1891 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00001892
Georg Brandl3ee81df2008-05-17 18:14:43 +00001893- Improve some exception messages when Windows fails to load an
1894 extension module. Now we get for example '%1 is not a valid Win32
1895 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00001896
Georg Brandl3ee81df2008-05-17 18:14:43 +00001897- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001899- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
1900 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00001901
Christian Heimes0a8143f2007-12-18 23:22:54 +00001902- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00001903 and INF. float("nan"), float("inf") and float("-inf") now work on
1904 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001905
Georg Brandl3ee81df2008-05-17 18:14:43 +00001906- Compiler now generates simpler and faster code for dictionary
1907 literals. The oparg for BUILD_MAP now indicates an estimated
1908 dictionary size. There is a new opcode, STORE_MAP, for adding
1909 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00001910
Georg Brandl3ee81df2008-05-17 18:14:43 +00001911- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00001912
Georg Brandl3ee81df2008-05-17 18:14:43 +00001913- Issue #1620: New property decorator syntax was modifying the
1914 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00001915
Georg Brandl3ee81df2008-05-17 18:14:43 +00001916- Issue #1538: Avoid copying string in split/rsplit if the split char
1917 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00001918
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00001919- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00001920 SystemError.
1921
Nick Coghlanef01d822007-12-03 12:55:17 +00001922- PEP 366: Allow explicit relative imports when executing modules
1923 inside packages with the -m switch via a new module level
1924 __package__ attribute.
1925
Georg Brandl3ee81df2008-05-17 18:14:43 +00001926- Issue #1402: Fix a crash on exit, when another thread is still
1927 running, and if the deallocation of its frames somehow calls the
1928 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00001929

1931
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00001932- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00001933 attribute of an empty cell object.
1934
Georg Brandl3ee81df2008-05-17 18:14:43 +00001935- Issue #1460: The utf-7 incremental decoder did not accept truncated
1936 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00001937

1939 file can now be directly executed by passing their name to the
1940 interpreter. The directory/zipfile is automatically inserted as the
1941 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00001942
Georg Brandl3ee81df2008-05-17 18:14:43 +00001943- Issue #1265: Fix a problem with sys.settrace, if the tracing
1944 function uses a generator expression when at the same time the
1945 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00001946
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00001947- sets and frozensets now have an isdisjoint() method.
1948
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00001949- optimize the performance of builtin.sum().
1950
Neal Norwitz44f326e2007-10-05 05:29:17 +00001951- Fix warnings found by the new version of the Coverity checker.
1952
Georg Brandl3ee81df2008-05-17 18:14:43 +00001953- The enumerate() builtin function is no longer bounded to sequences
1954 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
1955 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00001956
Georg Brandl3ee81df2008-05-17 18:14:43 +00001957- Issue #1686386: Tuple's tp_repr did not take into account the
1958 possibility of having a self-referential tuple, which is possible
1959 from C code. Nor did object's tp_str consider that a type's tp_str
1960 could do something that could lead to an inifinite recursion.
1961 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
1962 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00001963
Georg Brandl3ee81df2008-05-17 18:14:43 +00001964- Issue #1164: It was possible to trigger deadlock when using the
1965 'print' statement to write to a file since the GIL was not released
1966 as needed. Now PyObject_Print() does the right thing along with
1967 various tp_print implementations of the built-in types and those in
1968 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00001969
Georg Brandl3ee81df2008-05-17 18:14:43 +00001970- Issue #1147: Exceptions were directly allowing string exceptions in
1971 their throw() method even though string exceptions no longer
1972 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00001973
Georg Brandl3ee81df2008-05-17 18:14:43 +00001974- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00001977- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00001978 PyObject_Call() never calling back out to Python code to trigger
1979 recursion depth updates/checks. Required the creation of a static
1980 RuntimeError instance in case normalizing an exception put the
1981 recursion check value past its limit. Fixes crashers
1982 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00001983
Georg Brandl3ee81df2008-05-17 18:14:43 +00001984- Patch #1031213: Decode source line in SyntaxErrors back to its

Georg Brandl3ee81df2008-05-17 18:14:43 +00001998 __*__ attributes. (Some already existed, e.g., __doc__ and
1999 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00002008 "except E as target:". This is to provide forwards compatibility
2009 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002010
Brett Cannon229cee22007-05-05 01:34:02 +00002011- Deprecate BaseException.message as per PEP 352.

2029
Guido van Rossum143b5642007-03-23 04:58:42 +00002030- Bug #1683368: The object.__init__() and object.__new__() methods are
2031 now stricter in rejecting excess arguments. The only time when
2032 either allows excess arguments is when it is not overridden and the
2033 other one is. For backwards compatibility, when both are
2034 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002035 warning later). Also, type.__init__() insists on the same signature
2036 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002037
Georg Brandl3ee81df2008-05-17 18:14:43 +00002038- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2039 object to complex using its __complex__() method before falling back
2040 to the __float__() method. Therefore, the functions in the cmath
2041 module now can operate on objects that define a __complex__()
2042 method.

2059
Georg Brandl7b9c5552007-03-12 14:30:05 +00002060- Bug #1678647: write a newline after printing an exception in any
2061 case, even when converting the value to a string failed.
2062
Georg Brandl871f1bc2007-03-12 13:17:36 +00002063- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002064 its argument, if it exists. If not, it will work like before. This
2065 allows customizing the output of dir() in the presence of a
2066 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002067
Collin Winter276887b2007-03-12 16:11:39 +00002068- Patch #922167: Python no longer segfaults when faced with infinitely
2069 self-recursive reload() calls (as reported by bug #742342).

2075 parthensized forms. This means complex(repr(x)) now works instead of
2076 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002077
Georg Brandlaa2321b2007-03-07 00:40:28 +00002078- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002079 makes the filenames the warning module prints much more sensible
2080 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002081

Georg Brandl0fca97a2007-03-05 22:28:08 +00002093- Patch #1674228: when assigning a slice (old-style), check for the
2094 sq_ass_slice instead of the sq_slice slot.
2095
Georg Brandl3ee81df2008-05-17 18:14:43 +00002096- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00002722- unittest now verifies more of its assumptions. In particular,
2723 TestCase and TestSuite subclasses (not instances) are no longer
2724 accepted in TestSuite.addTest(). This should cause no
2725 incompatibility since it never made sense with ordinary subclasses
2726 -- the failure just occurred later, with a more cumbersome
2727 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003008- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3009 with RFC 3207 and forgets any knowledge obtained from the server not
3010 obtained from the TLS negotiation itself. Patch contributed by Bill
3011 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003012
Georg Brandl3ee81df2008-05-17 18:14:43 +00003013- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003014 that the SMTP.starttls() caller no longer needs to call ehlo()
3015 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003016 does not claim to support starttls. Adds the
3017 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3098 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3099 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003116 time so that opening a database previously created with the DB_DUP
3117 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3118 opens. Specifically: dictionary assignment to a DB object will
3119 replace all values for a given key when the database allows
3120 duplicate values. DB users should use DB.put(k, v) when they want
3121 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003122

3128 characters with ASCII value less than 32. Also, it correctly quotes
3129 dots only if they occur on a single line, as opposed to the previous
3130 behavior of quoting dots if they are the second character of any
3131 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003132

Georg Brandl3ee81df2008-05-17 18:14:43 +00003461- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3462 to ``PyTuple_SetItem``, it can be used to populate a brand new
3463 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003465- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003467- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3468 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3469 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003470
3471- Patch #1720595: add T_BOOL to the range of structmember types.
3472
3473- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3474 ``PyFloat_GetInfo()`` to the float API.
3475
Georg Brandl3ee81df2008-05-17 18:14:43 +00003476- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3477 of w# format code incorrectly truncated the length to an int, even
3478 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3479 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003480
Georg Brandl3ee81df2008-05-17 18:14:43 +00003481- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3482 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003483
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- PEP 3123: Provide forward compatibility with Python 3.0, while
3485 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3486 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003487
Georg Brandl3ee81df2008-05-17 18:14:43 +00003488- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3489 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003490
3491- Patch #1733960: Allow T_LONGLONG to accept ints.
3492
3493- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3494
Christian Heimes000a0742008-01-03 22:16:32 +00003495- Added a new API function ``PyImport_ImportModuleNoBlock``.
3496
Georg Brandl6caad7d2008-01-26 14:19:22 +00003497- Bug #1637022: Prefix AST symbols with _Py_.
3498
3499- Fix some leftovers from the conversion from int to Py_ssize_t
3500 (relevant to strings and sequences of more than 2**31 items).
3501
3502- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3503 outside of pystate.c and should not be necessary.
3504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3506 absolute imports. In earlier versions they might have used relative
3507 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003508
Georg Brandl3ee81df2008-05-17 18:14:43 +00003509- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3510 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003511
Georg Brandl3ee81df2008-05-17 18:14:43 +00003512- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3513 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003519- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3520 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3521 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3522 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003523
Georg Brandl3ee81df2008-05-17 18:14:43 +00003524- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00003535- buildtools now raises a DeprecationWarning.
3536
Georg Brandl3ee81df2008-05-17 18:14:43 +00003537- Removed the macfs module. It had been deprecated since Python 2.5.
3538 This lead to the deprecation of macostools.touched() as it relied
3539 solely on macfs and was a no-op under OS X.
