1029 do an explicit seek to the end of file (so that e.g. tell() returns the
1030 file size rather than 0). This is consistent with the behaviour of the

1227What's New in Python 2.6.1
1228==========================
1229
1230*Release date: 04-Dec-2008*
1231
1232Core and Builtins
1233-----------------
1234
1235- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1236 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1237 instead of throwing a MemoryError.
1238
1239- Issue #4367: Python would segfault during compiling when the unicodedata
1240 module couldn't be imported and \N escapes were present.
1241
1242- Issue #4348: Some bytearray methods returned that didn't cause any change to
1243 the bytearray, returned the same bytearray instead of a copy.
1244
1245- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1246
1247- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1248
1249- Issue #4048: The parser module now correctly validates relative imports.
1250
1251- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1252 exec statement.
1253
1254- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1255 method does not return iterators for the 4th and 5th items.
1256
1257- Issue #4209: Enabling unicode_literals and the print_function in the same
1258 __future__ import didn't work.
1259
1260- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1261 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1262 really executed because I cannot move to such directory on win2k)
1263
1264- Issue #4069: When set.remove(element) is used with a set element, the element
1265 is temporarily replaced with an equivalent frozenset. But the eventual
1266 KeyError would always report the empty frozenset([]) as the missing key. Now
1267 it correctly refers to the initial element.
1268
1269- Fixed C99 style comments in several files. Python is now C89 compatible
1270 again.
1271
1272Library

1418
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001419- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1420 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1421 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1422 ``printf`` function, whereas PyString_FromFormat has an independent
1423 implementation and uses "%zd" on all platforms for size_t values.
1424 This makes a difference on win64, where ``printf`` needs "%Id" to display
1425 64bit values.

1431 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001442 was correctly parsed but parsing of subsequent arguments failed.
1443
Vinay Sajip35e3b032008-09-01 14:33:59 +00001444- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001445 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1446 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1447 when given a tuple of classes as second argument, were looking up
1448 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1449 type object.

1590Core and Builtins
1591-----------------
1592
Guido van Rossumf8402962008-08-20 15:01:50 +00001593- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1594 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1595 extensions do not automatically benefit from the class attribute
1596 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1597 to their tp_flags field if they care. This is a backwards
1598 compatibility feature; in 3.0, all types will use the cache by
1599 default.
1600
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001601- Keyword arguments can now follow starred arguments. (``f(a, *args,
1602 keyword=23)`` is now valid syntax.)
1603
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001604- ctypes function pointers that are COM methods have a boolean True
1605 value again.
1606
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001607- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1608 by denying s# to parse objects that have a releasebuffer procedure,
1609 and introducing s*.
1610
Georg Brandl1e13ea92008-08-11 09:07:59 +00001611- Issue #3537: Fix an assertion failure when an empty but presized dict
1612 object was stored in the freelist.
1613
Mark Dickinsonb6467572008-08-04 21:30:09 +00001614- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1615 ValueError consistently across platforms.
1616
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001617- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1618 (64bit Unix, for example), unichr() would truncate its argument and return
1619 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1620
Neal Norwitze7d8be82008-07-31 17:17:14 +00001621- Apply security patches from Apple.
1622
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001623- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1624 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1625
Antoine Pitrou92f82162008-07-25 22:22:08 +00001626- Issue #1819: function calls with several named parameters are now on
1627 average 35% faster (as measured by pybench).
1628
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001629- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1630 the python debugger steps into a class statement: the free variables (local
1631 variables defined in an outer scope) would be deleted from the outer scope.
1632
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001633- Issue #2620: Overflow checking when allocating or reallocating memory
1634 was not always being done properly in some python types and extension
1635 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1636 all been updated to perform better checks and places in the code that
1637 would previously leak memory on the error path when such an allocation
1638 failed have been fixed.

1641-------
1642
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001643- Issue #3612: Added some missing basic types in ctypes.wintypes.
1644
Benjamin Petersone977ad42008-08-20 01:42:01 +00001645- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1646 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1647
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001648- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1649 version reported by these tools does not necessarily follow the python
1650 version numbering scheme, so the module is less strict when parsing it.
1651
Nick Coghlanf70385a2008-08-18 12:42:46 +00001652- Issue #2235: Added Py3k warnings for types which will become unhashable
1653 under the stricter __hash__ inheritance rules in 3.0. Several types
1654 which did not meet the rules for hash invariants and were already
1655 unhashable in 3.0 have now been explicitly flagged as unhashable in
1656 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1657 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1658
Brett Cannon88f801d2008-08-18 00:46:22 +00001659- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1660 imported into the module but exposed as part of the module's API.
1661
Brett Cannon7b96f072008-08-18 00:41:11 +00001662- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1663
Brett Cannon46225e72008-08-18 00:36:52 +00001664- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1665
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001666- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1667
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001668- Issue #3575: Incremental decoder's decode function now takes bytearray
1669 by using 's*' instead of 't#'.
1670
Jesus Cea585ad8a2009-07-02 15:37:21 +00001671- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001672 fails unicode conversion on 2nd parameter. (windows only)
1673
Facundo Batista94f243a2008-08-17 03:38:39 +00001674- Issue 2464. urllib2 now supports a malformation in the URL received
1675 in a redirect.
1676
Brett Cannonabe423e2008-08-16 21:47:07 +00001677- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001678 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001679
Facundo Batistaeb90b782008-08-16 14:44:07 +00001680- Issue #2776: fixed small issue when handling an URL with double slash
1681 after a 302 response in the case of not going through a proxy.
1682
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001683- Issue #2676: in the email package, content-type parsing was hanging on
1684 pathological input because of quadratic or exponential behaviour of a
1685 regular expression.
1686
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001687- Issue #3476: binary buffered reading through the new "io" library is now
1688 thread-safe.
1689
Brett Cannonbf3157b2008-08-14 05:00:03 +00001690- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1691 since mimetools itself is deprecated. Because modules are cached, all
1692 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1693
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001694- Issue #3134: shutil referenced undefined WindowsError symbol.
1695
Robert Schuppenies14646332008-08-10 11:01:53 +00001696- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1697 menu entries were not deleted.
1698
Brett Cannon83e81842008-08-09 23:30:55 +00001699- Copied the implementation of reduce() to _functools.reduce() to have a
1700 version that did not raise a DeprecationWarning under -3.
1701
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001702- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1703 a MemoryError rather than silently stop the iteration.
1704
Guido van Rossum59ce9012008-08-09 14:55:34 +00001705- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1706 to _sre.compile() will now be rejected. This should not affect anybody
1707 since the re.compile() function never generates invalid re-bytecode.
1708
Skip Montanaroa032bf42008-08-08 22:52:51 +00001709- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1710 upon first access it can be automatically initialized from the csv file if
1711 it wasn't initialized during instantiation.
1712
Brett Cannon3aa2a492008-08-06 22:28:09 +00001713- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1714 the reload() built-in has been removed.
1715
Brett Cannon7e30b672008-08-04 21:52:25 +00001716- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001717 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001718 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1719 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1720 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1721 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1722 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001723
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001724- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1725 raised an AttributeError.
1726
Benjamin Peterson01a24322008-07-28 23:35:27 +00001727- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001728 asking for a specific length. This problem only affected files opened
1729 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001730
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001731- Issue #3449: Update decimal module to use most recent specification
1732 (v. 1.68) and tests (v. 2.58) from IBM.
1733
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001734- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1735
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001736- Issue 1592: Improve error reporting when operations are attempted
1737 on a closed shelf.
1738

1740
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001741- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1742
1743- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1744 invalid arguments.
1745
1746- Issue #3302: Fix several crashes when calling locale's gettext functions
1747 with None arguments.
1748
1749- Issue #3389: Allow resolving dotted names for handlers in logging
1750 configuration files.
1751
1752- Deprecate the sunaudio module for removal in Python 3.0.
1753
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001754- Issue #3394: zipfile.writestr sets external attributes when passed a
1755 file name rather than a ZipInfo instance, so files are extracted with
1756 mode 0600 rather than 000 under Unix.
1757
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001758- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1759 argument in python 2.5, this broke code that subclassed Popen to include its
1760 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1768-------------
1769
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001770- Issue #2235: the C API function PyObject_HashNotImplemented and its
1771 interaction with the tp_hash slot (added in 2.6b2) are now documented
1772
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001773- Issue #643841: The language reference now provides more detailed
1774 coverage of the lookup process for special methods. The disclaimers
1775 regarding lack of coverage of new-style classes have also been
1776 removed, since the coverage is now fairly reasonable.

1785-----------------
1786
Georg Brandl3e483f62008-07-16 22:57:41 +00001787- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1788 its methods now allow for items objects that can be converted to
1789 an integer using operator.index().
1790
Mark Dickinson64b7e502008-07-16 09:40:03 +00001791- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1792 produced a ValueError instead of giving the correct float.
1793
Eric Smitha5fa5a22008-07-16 00:11:49 +00001794- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1795 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1796
Mark Dickinson7103aa42008-07-15 19:08:33 +00001797- Issue #3008: the float type has a new instance method 'float.hex'
1798 and a new class method 'float.fromhex' to convert floating-point
1799 numbers to and from hexadecimal strings, respectively.
1800
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001801- Issue #2235: __hash__ is once again inherited by default. To allow
1802 collections.Hashable to remain meaningful in the presence of the
1803 default hash implementation (object.__hash__), it is now possible
1804 to explicit block inheritance of hash by setting __hash__=None at
1805 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1806 level.
1807
Nick Coghlanb028f502008-07-13 14:52:36 +00001808- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1809 the parent module cannot be found while performing an absolute import.
1810 This means that an incorrectly defined __package__ attribute will
1811 now only prevent relative imports in that module rather than causing
1812 all imports from that module to fail.
1813
Nick Coghlan14ff9942008-07-08 14:21:42 +00001814- Issue #2517: Allow unicode messages in Exceptions again by correctly
1815 bypassing the instance dictionary when looking up __unicode__ on
1816 new-style classes.
1817
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001818- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1819 set to a custom object whose write() method happens to install
1820 another file in sys.stdout.
1821
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001822- Issue #3088: Corrected a race condition in classes derived from
1823 threading.local: the first member set by a thread could be saved in
1824 another thread's dictionary.
1825
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001826- Issue #3004: Minor change to slice.indices(): the start and stop
1827 arguments are now treated identically, making the behaviour easier
1828 to describe and understand. For example, slice(None, -10,
1829 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1830 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1831 10, -1).
1832
Georg Brandl278fc502008-07-19 12:46:12 +00001833- Issue #3219: Calling a function with repeated keyword arguments,
1834 f(a=2, a=23), would not cause a syntax error. This was a regression
1835 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001836
Georg Brandl278fc502008-07-19 12:46:12 +00001837- Issue #2862: Make int and float freelist management consistent with
1838 other freelists. Changes their CompactFreeList apis into
1839 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001844- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1845 api functions without holding the GIL, which could lead to a fatal
1846 error when they failed.
1847
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001848- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001856- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1857 ForkingPickler.register() to resolve conflict with ctypes.
1858
Vinay Sajip51e65192008-07-18 09:01:10 +00001859- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00001861- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1862 a valid dlerror() message.
1863
Thomas Heller2bad6572008-07-15 17:19:50 +00001864- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1865 incomplete structure was created.
1866
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001867- Issue #3339: dummy_thread.acquire() should not return None.
1868
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001869- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1870
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001871- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001872
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001873- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1874 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001875 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001876 content-length. The problem had been corrected in the 2.4 branch, but never

2284 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002285 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002286
2287 This is controlled by the configure argument ``--with-universal-archs``:
2288
2289 - ``--with-universal-archs=all``: install 4-way universal
2290
2291 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2292
2293 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2294
2295 This option should be used in combination with ``--enable-universalsdk=``.
2296
2297 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 +00002347- Issue #1631171: Re-implement the 'warnings' module in C (the
2348 original Python code has been kept as backup). This will allow for
2349 using the 'warning's machinery in such places as the parser where
2350 use of pure Python code is not possible. Both the ``showarning()``
2351 and ``formatwarning()`` gain an optional 'line' argument which is
2352 not called by default for backwards-compatibility reasons. Setting
2353 ``warnings.showwarning()`` to an implementation that lacks support
2354 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002379- The getpass module has been improved on Unix. It now uses /dev/tty
2380 by default and uses stderr instead of stdout. A GetPassWarning is
2381 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002417- Issue #2550: The approach used by client/server code for obtaining
2418 ports to listen on in network-oriented tests has been refined in an
2419 effort to facilitate running multiple instances of the entire
2420 regression test suite in parallel without issue.
2421 test_support.bind_port() has been fixed such that it will always
2422 return a unique port -- which wasn't always the case with the
2423 previous implementation, especially if socket options had been set
2424 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2425 new implementation of bind_port() will actually raise an exception
2426 if it is passed an AF_INET/SOCK_STREAM socket with either the
2427 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2428 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2429 the socket it's been passed. This currently only applies to
2430 Windows. This option prevents any other sockets from binding to the
2431 host/port we've bound to, thus removing the possibility of the
2432 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2433 when a second SOCK_STREAM socket binds and accepts to a host/port
2434 that's already been bound by another socket. The optional preferred
2435 port parameter to bind_port() has been removed. Under no
2436 circumstances should tests be hard coding ports!
2437
2438 test_support.find_unused_port() has also been introduced, which will
2439 pass a temporary socket object to bind_port() in order to obtain an
2440 unused port. The temporary socket object is then closed and
2441 deleted, and the port is returned. This method should only be used
2442 for obtaining an unused port in order to pass to an external program
2443 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2444 a parameter to a server-oriented class that doesn't give you direct
2445 access to the underlying socket used.
2446
2447 Finally, test_support.HOST has been introduced, which should be used
2448 for the host argument of any relevant socket calls (i.e. bind and
2449 connect).

2457 suite to run in parallel without issue.

2723Core and builtins
2724-----------------
2725
Fred Drakea8ee94b2008-03-01 02:45:07 +00002726- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002727 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002728
Georg Brandlad61bc82008-02-23 15:11:18 +00002729- Issue #2067: file.__exit__() now calls subclasses' close() method.
2730
2731- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002732
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002733- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002734 issue 215555 for a discussion.
2735
Eric Smitha73fbe72008-02-23 03:09:44 +00002736- Added the future_builtins module, which contains hex() and oct().
2737 These are the PEP 3127 version of these functions, designed to be
2738 compatible with the hex() and oct() builtins from Python 3.0. They
2739 differ slightly in their output formats from the existing, unchanged
2740 Python 2.6 builtins. The expected usage of the future_builtins
2741 module is:
2742 from future_builtins import hex, oct
2743
Eric Smith7ef40bf2008-02-20 23:34:22 +00002744- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2745 exponents for exponents with absolute value < 100. Follows C99
2746 standard. This is a change on Windows, which would use 3 digits.
2747 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2748 so that any alterations it does to the resulting string will be
2749 available in stringlib/formatter.h (for float.__format__).
2750
Eric Smith5a3c1352008-02-19 13:21:56 +00002751- Implemented PEP 3101, Advanced String Formatting. This adds a new
2752 builtin format(); a format() method for str and unicode; a
2753 __format__() method to object, str, unicode, int, long, float, and
2754 datetime; the class string.Formatter; and the C API
2755 PyObject_Format().
2756
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757- Fixed several potential crashes, all caused by specially crafted
2758 __del__ methods exploiting objects in temporarily inconsistent
2759 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002760
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002761- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762 prevent a possible crash: an Abstract Base Class would try to access
2763 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002764
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765- Fixed repr() and str() of complex numbers with infinity or nan as
2766 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002767
Georg Brandl3ee81df2008-05-17 18:14:43 +00002768- Clear all free lists during a gc.collect() of the highest generation
2769 in order to allow pymalloc to free more arenas. Python may give back
2770 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002771
Georg Brandl3ee81df2008-05-17 18:14:43 +00002772- Issue #2045: Fix an infinite recursion triggered when printing a
2773 subclass of collections.defaultdict, if its default_factory is set
2774 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002775
Christian Heimesf75dbef2008-02-08 00:11:31 +00002776- Fixed a minor memory leak in dictobject.c. The content of the free
2777 list was not freed on interpreter shutdown.
2778
Georg Brandl3ee81df2008-05-17 18:14:43 +00002779- Limit free list of method and builtin function objects to 256
2780 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002781
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2783 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002784 to compact the internal free lists of pre-allocted ints and floats.
2785
Georg Brandl3ee81df2008-05-17 18:14:43 +00002786- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2787 calls. Python expected the return type int but the fork familie
2788 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002789
Georg Brandl3ee81df2008-05-17 18:14:43 +00002790- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2791 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002792
Georg Brandl3ee81df2008-05-17 18:14:43 +00002793- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2794 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002795
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2797 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002798
Georg Brandl3ee81df2008-05-17 18:14:43 +00002799- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2800 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002801
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802- Patch #1473257: generator objects gain a gi_code attribute. This is
2803 the same object as the func_code attribute of the function that
2804 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002805
Georg Brandl3ee81df2008-05-17 18:14:43 +00002806- Issue #1920: "while 0" statements were completely removed by the
2807 compiler, even in the presence of an "else" clause, which is
2808 supposed to be run when the condition is false. Now the compiler
2809 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002810
Guido van Rossumeead05f2008-01-24 18:21:02 +00002811- A few crashers fixed: weakref_in_del.py (issue #1377858);
2812 loosing_dict_ref.py (issue #1303614, test67.py);
2813 borrowed_ref_[34].py (not in tracker).
2814
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002815- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002816 suppressed while an extension is loaded by calling SetErrorMode in
2817 dynload_win.c. The error is still reported properly.
2818
Georg Brandl3ee81df2008-05-17 18:14:43 +00002819- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002820 several extension methods and modules do not work without unicode
2821 support.
2822
Georg Brandl26543b12008-01-21 18:36:51 +00002823- Issue #1882: when compiling code from a string, encoding cookies in the
2824 second line of code were not always recognized correctly.
2825
Georg Brandl14404b62008-01-19 19:27:05 +00002826- Issue #1679: "0x" was taken as a valid integer literal.
2827
Georg Brandl6caad7d2008-01-26 14:19:22 +00002828- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002829 added.
2830
Christian Heimesc94e2b52008-01-14 04:13:37 +00002831- sys.float_info / PyFloat_GetInfo: The floating point information
2832 object was converted from a dict to a specialized structseq object.
2833
Georg Brandl3ee81df2008-05-17 18:14:43 +00002834- Patch #1816: Added sys.flags structseq. It exposes the status of
2835 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002836
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837- Objects/structseq.c: Implemented new structseq representation. The
2838 patch makes structseqs (e.g. the return value of os.stat) more
2839 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002840
Georg Brandl3ee81df2008-05-17 18:14:43 +00002841- Patch #1700288: added a type attribute cache that caches method
2842 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002843
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002844- Bug #1776: __import__() no longer accepts filenames on any platform.
2845 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002846
Georg Brandlaed6c662008-01-07 17:25:53 +00002847- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2850 envvar and sys.dont_write_bytecode attribute. All these can be set
2851 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002852
Georg Brandl3ee81df2008-05-17 18:14:43 +00002853- Improve some exception messages when Windows fails to load an
2854 extension module. Now we get for example '%1 is not a valid Win32
2855 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002856
Georg Brandl3ee81df2008-05-17 18:14:43 +00002857- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002859- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2860 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002861
Christian Heimes0a8143f2007-12-18 23:22:54 +00002862- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863 and INF. float("nan"), float("inf") and float("-inf") now work on
2864 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002865
Georg Brandl3ee81df2008-05-17 18:14:43 +00002866- Compiler now generates simpler and faster code for dictionary
2867 literals. The oparg for BUILD_MAP now indicates an estimated
2868 dictionary size. There is a new opcode, STORE_MAP, for adding
2869 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002870
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002879- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002880 SystemError.
2881
Nick Coghlanef01d822007-12-03 12:55:17 +00002882- PEP 366: Allow explicit relative imports when executing modules
2883 inside packages with the -m switch via a new module level
2884 __package__ attribute.
2885
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886- Issue #1402: Fix a crash on exit, when another thread is still
2887 running, and if the deallocation of its frames somehow calls the
2888 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002889

2899 file can now be directly executed by passing their name to the
2900 interpreter. The directory/zipfile is automatically inserted as the
2901 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002902
Georg Brandl3ee81df2008-05-17 18:14:43 +00002903- Issue #1265: Fix a problem with sys.settrace, if the tracing
2904 function uses a generator expression when at the same time the
2905 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002906
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002907- sets and frozensets now have an isdisjoint() method.
2908
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002909- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00002911- Fix warnings found by the new version of the Coverity checker.
2912
Georg Brandl3ee81df2008-05-17 18:14:43 +00002913- The enumerate() builtin function is no longer bounded to sequences
2914 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2915 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002916
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- Issue #1686386: Tuple's tp_repr did not take into account the
2918 possibility of having a self-referential tuple, which is possible
2919 from C code. Nor did object's tp_str consider that a type's tp_str
2920 could do something that could lead to an inifinite recursion.
2921 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2922 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002923
Georg Brandl3ee81df2008-05-17 18:14:43 +00002924- Issue #1164: It was possible to trigger deadlock when using the
2925 'print' statement to write to a file since the GIL was not released
2926 as needed. Now PyObject_Print() does the right thing along with
2927 various tp_print implementations of the built-in types and those in
2928 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002929
Georg Brandl3ee81df2008-05-17 18:14:43 +00002930- Issue #1147: Exceptions were directly allowing string exceptions in
2931 their throw() method even though string exceptions no longer
2932 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002933
Georg Brandl3ee81df2008-05-17 18:14:43 +00002934- Issue #1096: Prevent a segfault from getting the repr of a very

Neal Norwitz0ac60192007-05-27 04:08:54 +00002957- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002958 __*__ attributes. (Some already existed, e.g., __doc__ and
2959 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002960
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002961- Add -3 option to the interpreter to warn about features that are

2966
Collin Winter62903052007-05-18 23:11:24 +00002967- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002968 "except E as target:". This is to provide forwards compatibility
2969 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002970
Brett Cannon229cee22007-05-05 01:34:02 +00002971- Deprecate BaseException.message as per PEP 352.
2972
Georg Brandl3ee81df2008-05-17 18:14:43 +00002973- Issue #1303614: don't expose object's __dict__ when the dict is

2975
Vinay Sajip8549ce32007-05-06 17:53:37 +00002976- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002977 setting a plain string, ie don't expand to single letter identifiers.
2978
Raymond Hettinger13936692007-04-11 18:40:58 +00002979- Request #1191699: Slices can now be pickled.
2980
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002981- Request #1193128: str.translate() now allows a None argument for

2989
Guido van Rossum143b5642007-03-23 04:58:42 +00002990- Bug #1683368: The object.__init__() and object.__new__() methods are
2991 now stricter in rejecting excess arguments. The only time when
2992 either allows excess arguments is when it is not overridden and the
2993 other one is. For backwards compatibility, when both are
2994 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002995 warning later). Also, type.__init__() insists on the same signature
2996 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2999 object to complex using its __complex__() method before falling back
3000 to the __float__() method. Therefore, the functions in the cmath
3001 module now can operate on objects that define a __complex__()
3002 method.

3019
Georg Brandl7b9c5552007-03-12 14:30:05 +00003020- Bug #1678647: write a newline after printing an exception in any
3021 case, even when converting the value to a string failed.
3022
Georg Brandl871f1bc2007-03-12 13:17:36 +00003023- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003024 its argument, if it exists. If not, it will work like before. This
3025 allows customizing the output of dir() in the presence of a
3026 __getattr__().

3036 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003037
Georg Brandlaa2321b2007-03-07 00:40:28 +00003038- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039 makes the filenames the warning module prints much more sensible
3040 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003041

Georg Brandl0fca97a2007-03-05 22:28:08 +00003053- Patch #1674228: when assigning a slice (old-style), check for the
3054 sq_ass_slice instead of the sq_slice slot.
3055
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056- When printing an unraisable error, don't print exceptions. before

3681
Georg Brandl3ee81df2008-05-17 18:14:43 +00003682- unittest now verifies more of its assumptions. In particular,

3684 accepted in TestSuite.addTest(). This should cause no
3685 incompatibility since it never made sense with ordinary subclasses
3686 -- the failure just occurred later, with a more cumbersome
3687 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003968- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3969 with RFC 3207 and forgets any knowledge obtained from the server not
3970 obtained from the TLS negotiation itself. Patch contributed by Bill
3971 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003972
Georg Brandl3ee81df2008-05-17 18:14:43 +00003973- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003974 that the SMTP.starttls() caller no longer needs to call ehlo()
3975 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003976 does not claim to support starttls. Adds the
3977 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4058 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4059 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004076 time so that opening a database previously created with the DB_DUP
4077 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4078 opens. Specifically: dictionary assignment to a DB object will
4079 replace all values for a given key when the database allows
4080 duplicate values. DB users should use DB.put(k, v) when they want
4081 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004082

4088 characters with ASCII value less than 32. Also, it correctly quotes
4089 dots only if they occur on a single line, as opposed to the previous
4090 behavior of quoting dots if they are the second character of any
4091 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004408- Makefile.pre.in(buildbottest): Run an optional script
4409 pybuildbot.identify to include some information about the build
4410 environment.

4414-----
4415
Georg Brandl3ee81df2008-05-17 18:14:43 +00004416- Unified naming convention for free lists and their limits. All free
4417 lists in Object/ are named ``free_list``, the counter ``numfree``
4418 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4419 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004420
Georg Brandl3ee81df2008-05-17 18:14:43 +00004421- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4422 to ``PyTuple_SetItem``, it can be used to populate a brand new
4423 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004424
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004425- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004426
Georg Brandl3ee81df2008-05-17 18:14:43 +00004427- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4428 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4429 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004430
4431- Patch #1720595: add T_BOOL to the range of structmember types.
4432
4433- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4434 ``PyFloat_GetInfo()`` to the float API.
4435
Georg Brandl3ee81df2008-05-17 18:14:43 +00004436- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4437 of w# format code incorrectly truncated the length to an int, even
4438 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4439 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004440
Georg Brandl3ee81df2008-05-17 18:14:43 +00004441- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4442 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004443
Georg Brandl3ee81df2008-05-17 18:14:43 +00004444- PEP 3123: Provide forward compatibility with Python 3.0, while
4445 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4446 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004447
Georg Brandl3ee81df2008-05-17 18:14:43 +00004448- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4449 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004450
4451- Patch #1733960: Allow T_LONGLONG to accept ints.
4452
4453- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4454
Christian Heimes000a0742008-01-03 22:16:32 +00004455- Added a new API function ``PyImport_ImportModuleNoBlock``.
4456
Georg Brandl6caad7d2008-01-26 14:19:22 +00004457- Bug #1637022: Prefix AST symbols with _Py_.
4458
4459- Fix some leftovers from the conversion from int to Py_ssize_t
4460 (relevant to strings and sequences of more than 2**31 items).
4461
4462- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4463 outside of pystate.c and should not be necessary.
4464
Georg Brandl3ee81df2008-05-17 18:14:43 +00004465- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4466 absolute imports. In earlier versions they might have used relative
4467 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004468
Georg Brandl3ee81df2008-05-17 18:14:43 +00004469- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4470 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004471
Georg Brandl3ee81df2008-05-17 18:14:43 +00004472- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4473 macro so it can be used as an expression.

4478
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4480 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4481 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4482 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004483
Georg Brandl3ee81df2008-05-17 18:14:43 +00004484- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4485 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004497- Removed the macfs module. It had been deprecated since Python 2.5.
4498 This lead to the deprecation of macostools.touched() as it relied
4499 solely on macfs and was a no-op under OS X.
