91 primitives such as Lock, RLock, Condition, Event and Semaphore.
92
Antoine Pitrou641d76f2009-10-27 13:04:15 +000093- Issue #7055: test___all__ now greedily detects all modules which have an

745 do an explicit seek to the end of file (so that e.g. tell() returns the
746 file size rather than 0). This is consistent with the behaviour of the
747 traditional 2.x file object.

782 302 conformant loader) will now work correctly in most cases (they
783 are still subject to the constraints that exist for all code running

943What's New in Python 2.6.1
944==========================
945
946*Release date: 04-Dec-2008*
947
948Core and Builtins
949-----------------
950
951- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
952 interpreter to abort ("Fatal Python error: Could not reset the stack!")
953 instead of throwing a MemoryError.
954
955- Issue #4367: Python would segfault during compiling when the unicodedata
956 module couldn't be imported and \N escapes were present.
957
958- Issue #4348: Some bytearray methods returned that didn't cause any change to
959 the bytearray, returned the same bytearray instead of a copy.
960
961- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
962
963- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
964
965- Issue #4048: The parser module now correctly validates relative imports.
966
967- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
968 exec statement.
969
970- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
971 method does not return iterators for the 4th and 5th items.
972
973- Issue #4209: Enabling unicode_literals and the print_function in the same
974 __future__ import didn't work.
975
976- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
977 returned a path longer than MAX_PATH. (But It's doubtful this code path is
978 really executed because I cannot move to such directory on win2k)
979
980- Issue #4069: When set.remove(element) is used with a set element, the element
981 is temporarily replaced with an equivalent frozenset. But the eventual
982 KeyError would always report the empty frozenset([]) as the missing key. Now
983 it correctly refers to the initial element.
984
985- Fixed C99 style comments in several files. Python is now C89 compatible
986 again.
987
988Library

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001133- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1134
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001135- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1136 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1137 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1138 ``printf`` function, whereas PyString_FromFormat has an independent
1139 implementation and uses "%zd" on all platforms for size_t values.
1140 This makes a difference on win64, where ``printf`` needs "%Id" to display
1141 64bit values.

1147 object; previously an int would be returned for small values. the __long__

1149 float objects should not change to respect backward compatibility.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001158 was correctly parsed but parsing of subsequent arguments failed.
1159
Vinay Sajip35e3b032008-09-01 14:33:59 +00001160- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001161 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1162 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1163 when given a tuple of classes as second argument, were looking up
1164 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1165 type object.
1166

1306Core and Builtins
1307-----------------
1308
Guido van Rossumf8402962008-08-20 15:01:50 +00001309- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1310 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1311 extensions do not automatically benefit from the class attribute
1312 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1313 to their tp_flags field if they care. This is a backwards
1314 compatibility feature; in 3.0, all types will use the cache by
1315 default.
1316
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001317- Keyword arguments can now follow starred arguments. (``f(a, *args,
1318 keyword=23)`` is now valid syntax.)
1319
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001320- ctypes function pointers that are COM methods have a boolean True
1321 value again.
1322
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001323- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1324 by denying s# to parse objects that have a releasebuffer procedure,
1325 and introducing s*.
1326
Georg Brandl1e13ea92008-08-11 09:07:59 +00001327- Issue #3537: Fix an assertion failure when an empty but presized dict
1328 object was stored in the freelist.
1329
Mark Dickinsonb6467572008-08-04 21:30:09 +00001330- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1331 ValueError consistently across platforms.
1332
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001333- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1334 (64bit Unix, for example), unichr() would truncate its argument and return
1335 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1336
Neal Norwitze7d8be82008-07-31 17:17:14 +00001337- Apply security patches from Apple.
1338
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001339- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1340 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1341
Antoine Pitrou92f82162008-07-25 22:22:08 +00001342- Issue #1819: function calls with several named parameters are now on
1343 average 35% faster (as measured by pybench).
1344
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001345- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1346 the python debugger steps into a class statement: the free variables (local
1347 variables defined in an outer scope) would be deleted from the outer scope.
1348
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001349- Issue #2620: Overflow checking when allocating or reallocating memory
1350 was not always being done properly in some python types and extension
1351 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1352 all been updated to perform better checks and places in the code that
1353 would previously leak memory on the error path when such an allocation
1354 failed have been fixed.

1357-------
1358
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001359- Issue #3612: Added some missing basic types in ctypes.wintypes.
1360
Benjamin Petersone977ad42008-08-20 01:42:01 +00001361- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1362 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1363
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001364- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1365 version reported by these tools does not necessarily follow the python
1366 version numbering scheme, so the module is less strict when parsing it.
1367
Nick Coghlanf70385a2008-08-18 12:42:46 +00001368- Issue #2235: Added Py3k warnings for types which will become unhashable
1369 under the stricter __hash__ inheritance rules in 3.0. Several types
1370 which did not meet the rules for hash invariants and were already
1371 unhashable in 3.0 have now been explicitly flagged as unhashable in
1372 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1373 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1374
Brett Cannon88f801d2008-08-18 00:46:22 +00001375- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1376 imported into the module but exposed as part of the module's API.
1377
Brett Cannon7b96f072008-08-18 00:41:11 +00001378- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1379
Brett Cannon46225e72008-08-18 00:36:52 +00001380- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1381
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001382- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1383
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001384- Issue #3575: Incremental decoder's decode function now takes bytearray
1385 by using 's*' instead of 't#'.
1386
Jesus Cea585ad8a2009-07-02 15:37:21 +00001387- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001388 fails unicode conversion on 2nd parameter. (windows only)
1389
Facundo Batista94f243a2008-08-17 03:38:39 +00001390- Issue 2464. urllib2 now supports a malformation in the URL received
1391 in a redirect.
1392
Brett Cannonabe423e2008-08-16 21:47:07 +00001393- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001394 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001395
Facundo Batistaeb90b782008-08-16 14:44:07 +00001396- Issue #2776: fixed small issue when handling an URL with double slash
1397 after a 302 response in the case of not going through a proxy.
1398
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001399- Issue #2676: in the email package, content-type parsing was hanging on
1400 pathological input because of quadratic or exponential behaviour of a
1401 regular expression.
1402
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001403- Issue #3476: binary buffered reading through the new "io" library is now
1404 thread-safe.
1405
Brett Cannonbf3157b2008-08-14 05:00:03 +00001406- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1407 since mimetools itself is deprecated. Because modules are cached, all
1408 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1409
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001410- Issue #3134: shutil referenced undefined WindowsError symbol.
1411
Robert Schuppenies14646332008-08-10 11:01:53 +00001412- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1413 menu entries were not deleted.
1414
Brett Cannon83e81842008-08-09 23:30:55 +00001415- Copied the implementation of reduce() to _functools.reduce() to have a
1416 version that did not raise a DeprecationWarning under -3.
1417
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001418- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1419 a MemoryError rather than silently stop the iteration.
1420
Guido van Rossum59ce9012008-08-09 14:55:34 +00001421- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1422 to _sre.compile() will now be rejected. This should not affect anybody
1423 since the re.compile() function never generates invalid re-bytecode.
1424
Skip Montanaroa032bf42008-08-08 22:52:51 +00001425- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1426 upon first access it can be automatically initialized from the csv file if
1427 it wasn't initialized during instantiation.
1428
Brett Cannon3aa2a492008-08-06 22:28:09 +00001429- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1430 the reload() built-in has been removed.
1431
Brett Cannon7e30b672008-08-04 21:52:25 +00001432- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001433 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001434 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1435 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1436 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1437 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1438 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001439
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001440- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1441 raised an AttributeError.
1442
Benjamin Peterson01a24322008-07-28 23:35:27 +00001443- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001444 asking for a specific length. This problem only affected files opened
1445 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001446
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001447- Issue #3449: Update decimal module to use most recent specification
1448 (v. 1.68) and tests (v. 2.58) from IBM.
1449
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001450- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1451
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001452- Issue 1592: Improve error reporting when operations are attempted
1453 on a closed shelf.
1454
Georg Brandlf9efabb2008-07-23 15:16:45 +00001455- Deprecate the "ast" parser function aliases.
1456
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001457- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1458
1459- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1460 invalid arguments.
1461
1462- Issue #3302: Fix several crashes when calling locale's gettext functions
1463 with None arguments.
1464
1465- Issue #3389: Allow resolving dotted names for handlers in logging
1466 configuration files.
1467
1468- Deprecate the sunaudio module for removal in Python 3.0.
1469
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001470- Issue #3394: zipfile.writestr sets external attributes when passed a
1471 file name rather than a ZipInfo instance, so files are extracted with
1472 mode 0600 rather than 000 under Unix.
1473
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001474- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1475 argument in python 2.5, this broke code that subclassed Popen to include its
1476 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1484-------------
1485
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001486- Issue #2235: the C API function PyObject_HashNotImplemented and its
1487 interaction with the tp_hash slot (added in 2.6b2) are now documented
1488
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001489- Issue #643841: The language reference now provides more detailed
1490 coverage of the lookup process for special methods. The disclaimers
1491 regarding lack of coverage of new-style classes have also been
1492 removed, since the coverage is now fairly reasonable.

1501-----------------
1502
Georg Brandl3e483f62008-07-16 22:57:41 +00001503- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1504 its methods now allow for items objects that can be converted to
1505 an integer using operator.index().
1506
Mark Dickinson64b7e502008-07-16 09:40:03 +00001507- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1508 produced a ValueError instead of giving the correct float.
1509
Eric Smitha5fa5a22008-07-16 00:11:49 +00001510- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1511 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1512
Mark Dickinson7103aa42008-07-15 19:08:33 +00001513- Issue #3008: the float type has a new instance method 'float.hex'
1514 and a new class method 'float.fromhex' to convert floating-point
1515 numbers to and from hexadecimal strings, respectively.
1516
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001517- Issue #2235: __hash__ is once again inherited by default. To allow
1518 collections.Hashable to remain meaningful in the presence of the
1519 default hash implementation (object.__hash__), it is now possible
1520 to explicit block inheritance of hash by setting __hash__=None at
1521 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1522 level.
1523
Nick Coghlanb028f502008-07-13 14:52:36 +00001524- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1525 the parent module cannot be found while performing an absolute import.
1526 This means that an incorrectly defined __package__ attribute will
1527 now only prevent relative imports in that module rather than causing
1528 all imports from that module to fail.
1529
Nick Coghlan14ff9942008-07-08 14:21:42 +00001530- Issue #2517: Allow unicode messages in Exceptions again by correctly
1531 bypassing the instance dictionary when looking up __unicode__ on
1532 new-style classes.
1533
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001534- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1535 set to a custom object whose write() method happens to install
1536 another file in sys.stdout.
1537
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001538- Issue #3088: Corrected a race condition in classes derived from
1539 threading.local: the first member set by a thread could be saved in
1540 another thread's dictionary.
1541
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001542- Issue #3004: Minor change to slice.indices(): the start and stop
1543 arguments are now treated identically, making the behaviour easier
1544 to describe and understand. For example, slice(None, -10,
1545 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1546 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1547 10, -1).
1548
Georg Brandl278fc502008-07-19 12:46:12 +00001549- Issue #3219: Calling a function with repeated keyword arguments,
1550 f(a=2, a=23), would not cause a syntax error. This was a regression
1551 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001552
Georg Brandl278fc502008-07-19 12:46:12 +00001553- Issue #2862: Make int and float freelist management consistent with
1554 other freelists. Changes their CompactFreeList apis into
1555 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001556

1558-------
1559
Thomas Heller57adf222008-08-14 19:10:48 +00001560- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1561 api functions without holding the GIL, which could lead to a fatal
1562 error when they failed.
1563
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001564- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
1565
Jesse Noller7fb96402008-07-17 21:01:05 +00001566- Issue #3395: fix reference in test_multiprocessing to old debugInfo method
1567
Georg Brandla24869a2008-07-16 22:33:18 +00001568- Issue #3312: Fix two crashes in sqlite3.

1571
Jesse Noller13e9d582008-07-16 14:32:36 +00001572- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1573 ForkingPickler.register() to resolve conflict with ctypes.
1574
Vinay Sajip51e65192008-07-18 09:01:10 +00001575- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001576
Thomas Heller880f5292008-07-15 19:39:38 +00001577- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1578 a valid dlerror() message.
1579
Thomas Heller2bad6572008-07-15 17:19:50 +00001580- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1581 incomplete structure was created.
1582
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001583- Issue #3339: dummy_thread.acquire() should not return None.
1584
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001585- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1586
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001587- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001588
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001589- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1590 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001591 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001592 content-length. The problem had been corrected in the 2.4 branch, but never

2000 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002001 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002002
2003 This is controlled by the configure argument ``--with-universal-archs``:
2004
2005 - ``--with-universal-archs=all``: install 4-way universal
2006
2007 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2008
2009 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2010
2011 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002063- Issue #1631171: Re-implement the 'warnings' module in C (the
2064 original Python code has been kept as backup). This will allow for
2065 using the 'warning's machinery in such places as the parser where
2066 use of pure Python code is not possible. Both the ``showarning()``
2067 and ``formatwarning()`` gain an optional 'line' argument which is
2068 not called by default for backwards-compatibility reasons. Setting
2069 ``warnings.showwarning()`` to an implementation that lacks support
2070 for the ``line`` argument will raise a DeprecationWarning.

2094
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002095- The getpass module has been improved on Unix. It now uses /dev/tty
2096 by default and uses stderr instead of stdout. A GetPassWarning is
2097 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002112- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002113 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002133- Issue #2550: The approach used by client/server code for obtaining
2134 ports to listen on in network-oriented tests has been refined in an
2135 effort to facilitate running multiple instances of the entire
2136 regression test suite in parallel without issue.
2137 test_support.bind_port() has been fixed such that it will always
2138 return a unique port -- which wasn't always the case with the
2139 previous implementation, especially if socket options had been set
2140 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2141 new implementation of bind_port() will actually raise an exception
2142 if it is passed an AF_INET/SOCK_STREAM socket with either the
2143 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2144 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2145 the socket it's been passed. This currently only applies to
2146 Windows. This option prevents any other sockets from binding to the
2147 host/port we've bound to, thus removing the possibility of the
2148 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2149 when a second SOCK_STREAM socket binds and accepts to a host/port
2150 that's already been bound by another socket. The optional preferred
2151 port parameter to bind_port() has been removed. Under no
2152 circumstances should tests be hard coding ports!
2153
2154 test_support.find_unused_port() has also been introduced, which will
2155 pass a temporary socket object to bind_port() in order to obtain an
2156 unused port. The temporary socket object is then closed and
2157 deleted, and the port is returned. This method should only be used
2158 for obtaining an unused port in order to pass to an external program
2159 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2160 a parameter to a server-oriented class that doesn't give you direct
2161 access to the underlying socket used.
2162
2163 Finally, test_support.HOST has been introduced, which should be used
2164 for the host argument of any relevant socket calls (i.e. bind and
2165 connect).

2439Core and builtins
2440-----------------
2441
Fred Drakea8ee94b2008-03-01 02:45:07 +00002442- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002443 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002444
Georg Brandlad61bc82008-02-23 15:11:18 +00002445- Issue #2067: file.__exit__() now calls subclasses' close() method.
2446
2447- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002448
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002449- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002450 issue 215555 for a discussion.
2451
Eric Smitha73fbe72008-02-23 03:09:44 +00002452- Added the future_builtins module, which contains hex() and oct().
2453 These are the PEP 3127 version of these functions, designed to be
2454 compatible with the hex() and oct() builtins from Python 3.0. They
2455 differ slightly in their output formats from the existing, unchanged
2456 Python 2.6 builtins. The expected usage of the future_builtins
2457 module is:
2458 from future_builtins import hex, oct
2459
Eric Smith7ef40bf2008-02-20 23:34:22 +00002460- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2461 exponents for exponents with absolute value < 100. Follows C99
2462 standard. This is a change on Windows, which would use 3 digits.
2463 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2464 so that any alterations it does to the resulting string will be
2465 available in stringlib/formatter.h (for float.__format__).
2466
Eric Smith5a3c1352008-02-19 13:21:56 +00002467- Implemented PEP 3101, Advanced String Formatting. This adds a new
2468 builtin format(); a format() method for str and unicode; a
2469 __format__() method to object, str, unicode, int, long, float, and
2470 datetime; the class string.Formatter; and the C API
2471 PyObject_Format().
2472
Georg Brandl3ee81df2008-05-17 18:14:43 +00002473- Fixed several potential crashes, all caused by specially crafted
2474 __del__ methods exploiting objects in temporarily inconsistent
2475 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002476
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002477- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002478 prevent a possible crash: an Abstract Base Class would try to access
2479 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002480
Georg Brandl3ee81df2008-05-17 18:14:43 +00002481- Fixed repr() and str() of complex numbers with infinity or nan as
2482 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002483
Georg Brandl3ee81df2008-05-17 18:14:43 +00002484- Clear all free lists during a gc.collect() of the highest generation
2485 in order to allow pymalloc to free more arenas. Python may give back
2486 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002487
Georg Brandl3ee81df2008-05-17 18:14:43 +00002488- Issue #2045: Fix an infinite recursion triggered when printing a
2489 subclass of collections.defaultdict, if its default_factory is set
2490 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002491
Christian Heimesf75dbef2008-02-08 00:11:31 +00002492- Fixed a minor memory leak in dictobject.c. The content of the free
2493 list was not freed on interpreter shutdown.
2494
Georg Brandl3ee81df2008-05-17 18:14:43 +00002495- Limit free list of method and builtin function objects to 256
2496 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002497
Georg Brandl3ee81df2008-05-17 18:14:43 +00002498- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2499 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002500 to compact the internal free lists of pre-allocted ints and floats.
2501
Georg Brandl3ee81df2008-05-17 18:14:43 +00002502- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2503 calls. Python expected the return type int but the fork familie
2504 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002505
Georg Brandl3ee81df2008-05-17 18:14:43 +00002506- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2507 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002508
Georg Brandl3ee81df2008-05-17 18:14:43 +00002509- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2510 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002511
Georg Brandl3ee81df2008-05-17 18:14:43 +00002512- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2513 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002514
Georg Brandl3ee81df2008-05-17 18:14:43 +00002515- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2516 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002517
Georg Brandl3ee81df2008-05-17 18:14:43 +00002518- Patch #1473257: generator objects gain a gi_code attribute. This is
2519 the same object as the func_code attribute of the function that
2520 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002521
Georg Brandl3ee81df2008-05-17 18:14:43 +00002522- Issue #1920: "while 0" statements were completely removed by the
2523 compiler, even in the presence of an "else" clause, which is
2524 supposed to be run when the condition is false. Now the compiler
2525 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002526
Guido van Rossumeead05f2008-01-24 18:21:02 +00002527- A few crashers fixed: weakref_in_del.py (issue #1377858);
2528 loosing_dict_ref.py (issue #1303614, test67.py);
2529 borrowed_ref_[34].py (not in tracker).
2530
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002531- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002532 suppressed while an extension is loaded by calling SetErrorMode in
2533 dynload_win.c. The error is still reported properly.
2534
Georg Brandl3ee81df2008-05-17 18:14:43 +00002535- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002536 several extension methods and modules do not work without unicode
2537 support.
2538
Georg Brandl26543b12008-01-21 18:36:51 +00002539- Issue #1882: when compiling code from a string, encoding cookies in the
2540 second line of code were not always recognized correctly.
2541
Georg Brandl14404b62008-01-19 19:27:05 +00002542- Issue #1679: "0x" was taken as a valid integer literal.
2543
Georg Brandl6caad7d2008-01-26 14:19:22 +00002544- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002545 added.
2546
Christian Heimesc94e2b52008-01-14 04:13:37 +00002547- sys.float_info / PyFloat_GetInfo: The floating point information
2548 object was converted from a dict to a specialized structseq object.
2549
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Patch #1816: Added sys.flags structseq. It exposes the status of
2551 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002552
Georg Brandl3ee81df2008-05-17 18:14:43 +00002553- Objects/structseq.c: Implemented new structseq representation. The
2554 patch makes structseqs (e.g. the return value of os.stat) more
2555 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002556
Georg Brandl3ee81df2008-05-17 18:14:43 +00002557- Patch #1700288: added a type attribute cache that caches method
2558 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002559
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002560- Bug #1776: __import__() no longer accepts filenames on any platform.
2561 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002562
Georg Brandlaed6c662008-01-07 17:25:53 +00002563- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2564
Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2566 envvar and sys.dont_write_bytecode attribute. All these can be set
2567 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002568
Georg Brandl3ee81df2008-05-17 18:14:43 +00002569- Improve some exception messages when Windows fails to load an
2570 extension module. Now we get for example '%1 is not a valid Win32
2571 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002572
Georg Brandl3ee81df2008-05-17 18:14:43 +00002573- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002575- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2576 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002577
Christian Heimes0a8143f2007-12-18 23:22:54 +00002578- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002579 and INF. float("nan"), float("inf") and float("-inf") now work on
2580 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002581
Georg Brandl3ee81df2008-05-17 18:14:43 +00002582- Compiler now generates simpler and faster code for dictionary
2583 literals. The oparg for BUILD_MAP now indicates an estimated
2584 dictionary size. There is a new opcode, STORE_MAP, for adding
2585 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002586
Georg Brandl3ee81df2008-05-17 18:14:43 +00002587- Issue #1638: %zd configure test fails on Linux.

2600 __package__ attribute.
2601
Georg Brandl3ee81df2008-05-17 18:14:43 +00002602- Issue #1402: Fix a crash on exit, when another thread is still
2603 running, and if the deallocation of its frames somehow calls the
2604 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002605

Georg Brandl3ee81df2008-05-17 18:14:43 +00002619- Issue #1265: Fix a problem with sys.settrace, if the tracing
2620 function uses a generator expression when at the same time the
2621 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002622
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002623- sets and frozensets now have an isdisjoint() method.
2624
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002625- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00002627- Fix warnings found by the new version of the Coverity checker.
2628
Georg Brandl3ee81df2008-05-17 18:14:43 +00002629- The enumerate() builtin function is no longer bounded to sequences
2630 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2631 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002632
Georg Brandl3ee81df2008-05-17 18:14:43 +00002633- Issue #1686386: Tuple's tp_repr did not take into account the
2634 possibility of having a self-referential tuple, which is possible
2635 from C code. Nor did object's tp_str consider that a type's tp_str
2636 could do something that could lead to an inifinite recursion.
2637 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2638 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002639
Georg Brandl3ee81df2008-05-17 18:14:43 +00002640- Issue #1164: It was possible to trigger deadlock when using the
2641 'print' statement to write to a file since the GIL was not released
2642 as needed. Now PyObject_Print() does the right thing along with
2643 various tp_print implementations of the built-in types and those in
2644 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002645
Georg Brandl3ee81df2008-05-17 18:14:43 +00002646- Issue #1147: Exceptions were directly allowing string exceptions in
2647 their throw() method even though string exceptions no longer
2648 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002649
Georg Brandl3ee81df2008-05-17 18:14:43 +00002650- Issue #1096: Prevent a segfault from getting the repr of a very

Neal Norwitz0ac60192007-05-27 04:08:54 +00002673- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002674 __*__ attributes. (Some already existed, e.g., __doc__ and
2675 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002676
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002677- Add -3 option to the interpreter to warn about features that are

2682
Collin Winter62903052007-05-18 23:11:24 +00002683- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002684 "except E as target:". This is to provide forwards compatibility
2685 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002686
Brett Cannon229cee22007-05-05 01:34:02 +00002687- Deprecate BaseException.message as per PEP 352.
2688
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Issue #1303614: don't expose object's __dict__ when the dict is

2691
Vinay Sajip8549ce32007-05-06 17:53:37 +00002692- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002693 setting a plain string, ie don't expand to single letter identifiers.
2694
Raymond Hettinger13936692007-04-11 18:40:58 +00002695- Request #1191699: Slices can now be pickled.

2705
Guido van Rossum143b5642007-03-23 04:58:42 +00002706- Bug #1683368: The object.__init__() and object.__new__() methods are
2707 now stricter in rejecting excess arguments. The only time when
2708 either allows excess arguments is when it is not overridden and the
2709 other one is. For backwards compatibility, when both are
2710 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002711 warning later). Also, type.__init__() insists on the same signature
2712 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002713
Georg Brandl3ee81df2008-05-17 18:14:43 +00002714- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2715 object to complex using its __complex__() method before falling back
2716 to the __float__() method. Therefore, the functions in the cmath
2717 module now can operate on objects that define a __complex__()
2718 method.

2735
Georg Brandl7b9c5552007-03-12 14:30:05 +00002736- Bug #1678647: write a newline after printing an exception in any
2737 case, even when converting the value to a string failed.
2738
Georg Brandl871f1bc2007-03-12 13:17:36 +00002739- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002740 its argument, if it exists. If not, it will work like before. This
2741 allows customizing the output of dir() in the presence of a
2742 __getattr__().

2752 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002753
Georg Brandlaa2321b2007-03-07 00:40:28 +00002754- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002755 makes the filenames the warning module prints much more sensible
2756 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002757

Georg Brandl0fca97a2007-03-05 22:28:08 +00002769- Patch #1674228: when assigning a slice (old-style), check for the
2770 sq_ass_slice instead of the sq_slice slot.
2771
Georg Brandl3ee81df2008-05-17 18:14:43 +00002772- When printing an unraisable error, don't print exceptions. before

3401 incompatibility since it never made sense with ordinary subclasses
3402 -- the failure just occurred later, with a more cumbersome
3403 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003684- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3685 with RFC 3207 and forgets any knowledge obtained from the server not
3686 obtained from the TLS negotiation itself. Patch contributed by Bill
3687 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003688
Georg Brandl3ee81df2008-05-17 18:14:43 +00003689- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003690 that the SMTP.starttls() caller no longer needs to call ehlo()
3691 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003692 does not claim to support starttls. Adds the
3693 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3774 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3775 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003792 time so that opening a database previously created with the DB_DUP
3793 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3794 opens. Specifically: dictionary assignment to a DB object will
3795 replace all values for a given key when the database allows
3796 duplicate values. DB users should use DB.put(k, v) when they want
3797 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003798

3804 characters with ASCII value less than 32. Also, it correctly quotes
3805 dots only if they occur on a single line, as opposed to the previous
3806 behavior of quoting dots if they are the second character of any
3807 line.

4130-----
4131
Georg Brandl3ee81df2008-05-17 18:14:43 +00004132- Unified naming convention for free lists and their limits. All free
4133 lists in Object/ are named ``free_list``, the counter ``numfree``
4134 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4135 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004136
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4138 to ``PyTuple_SetItem``, it can be used to populate a brand new
4139 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004140
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004141- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004142
Georg Brandl3ee81df2008-05-17 18:14:43 +00004143- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4144 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4145 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004146
4147- Patch #1720595: add T_BOOL to the range of structmember types.
4148
4149- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4150 ``PyFloat_GetInfo()`` to the float API.
4151
Georg Brandl3ee81df2008-05-17 18:14:43 +00004152- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4153 of w# format code incorrectly truncated the length to an int, even
4154 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4155 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004156
Georg Brandl3ee81df2008-05-17 18:14:43 +00004157- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4158 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004159
Georg Brandl3ee81df2008-05-17 18:14:43 +00004160- PEP 3123: Provide forward compatibility with Python 3.0, while
4161 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4162 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004163
Georg Brandl3ee81df2008-05-17 18:14:43 +00004164- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4165 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004166
4167- Patch #1733960: Allow T_LONGLONG to accept ints.
4168
4169- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4170
Christian Heimes000a0742008-01-03 22:16:32 +00004171- Added a new API function ``PyImport_ImportModuleNoBlock``.
4172
Georg Brandl6caad7d2008-01-26 14:19:22 +00004173- Bug #1637022: Prefix AST symbols with _Py_.
4174
4175- Fix some leftovers from the conversion from int to Py_ssize_t
4176 (relevant to strings and sequences of more than 2**31 items).
4177
4178- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4179 outside of pystate.c and should not be necessary.
4180
Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4182 absolute imports. In earlier versions they might have used relative
4183 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004184
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4186 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004187
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4189 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004195- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4196 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4197 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4198 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4201 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004213- Removed the macfs module. It had been deprecated since Python 2.5.
4214 This lead to the deprecation of macostools.touched() as it relied
4215 solely on macfs and was a no-op under OS X.
