1032 do an explicit seek to the end of file (so that e.g. tell() returns the
1033 file size rather than 0). This is consistent with the behaviour of the
1034 traditional 2.x file object.

1068- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1069 302 conformant loader) will now work correctly in most cases (they
1070 are still subject to the constraints that exist for all code running

1230What's New in Python 2.6.1
1231==========================
1232
1233*Release date: 04-Dec-2008*
1234
1235Core and Builtins
1236-----------------
1237
1238- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1239 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1240 instead of throwing a MemoryError.
1241
1242- Issue #4367: Python would segfault during compiling when the unicodedata
1243 module couldn't be imported and \N escapes were present.
1244
1245- Issue #4348: Some bytearray methods returned that didn't cause any change to
1246 the bytearray, returned the same bytearray instead of a copy.
1247
1248- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1249
1250- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1251
1252- Issue #4048: The parser module now correctly validates relative imports.
1253
1254- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1255 exec statement.
1256
1257- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1258 method does not return iterators for the 4th and 5th items.
1259
1260- Issue #4209: Enabling unicode_literals and the print_function in the same
1261 __future__ import didn't work.
1262
1263- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1264 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1265 really executed because I cannot move to such directory on win2k)
1266
1267- Issue #4069: When set.remove(element) is used with a set element, the element
1268 is temporarily replaced with an equivalent frozenset. But the eventual
1269 KeyError would always report the empty frozenset([]) as the missing key. Now
1270 it correctly refers to the initial element.
1271
1272- Fixed C99 style comments in several files. Python is now C89 compatible
1273 again.
1274
1275Library

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001420- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1421
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001422- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1423 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1424 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1425 ``printf`` function, whereas PyString_FromFormat has an independent
1426 implementation and uses "%zd" on all platforms for size_t values.
1427 This makes a difference on win64, where ``printf`` needs "%Id" to display
1428 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001430- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1434 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001445 was correctly parsed but parsing of subsequent arguments failed.
1446
Vinay Sajip35e3b032008-09-01 14:33:59 +00001447- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001448 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1449 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1450 when given a tuple of classes as second argument, were looking up
1451 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1452 type object.
1453

1593Core and Builtins
1594-----------------
1595
Guido van Rossumf8402962008-08-20 15:01:50 +00001596- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1597 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1598 extensions do not automatically benefit from the class attribute
1599 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1600 to their tp_flags field if they care. This is a backwards
1601 compatibility feature; in 3.0, all types will use the cache by
1602 default.
1603
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001604- Keyword arguments can now follow starred arguments. (``f(a, *args,
1605 keyword=23)`` is now valid syntax.)
1606
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001607- ctypes function pointers that are COM methods have a boolean True
1608 value again.
1609
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001610- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1611 by denying s# to parse objects that have a releasebuffer procedure,
1612 and introducing s*.
1613
Georg Brandl1e13ea92008-08-11 09:07:59 +00001614- Issue #3537: Fix an assertion failure when an empty but presized dict
1615 object was stored in the freelist.
1616
Mark Dickinsonb6467572008-08-04 21:30:09 +00001617- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1618 ValueError consistently across platforms.
1619
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001620- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1621 (64bit Unix, for example), unichr() would truncate its argument and return
1622 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1623
Neal Norwitze7d8be82008-07-31 17:17:14 +00001624- Apply security patches from Apple.
1625
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001626- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1627 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1628
Antoine Pitrou92f82162008-07-25 22:22:08 +00001629- Issue #1819: function calls with several named parameters are now on
1630 average 35% faster (as measured by pybench).
1631
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001632- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1633 the python debugger steps into a class statement: the free variables (local
1634 variables defined in an outer scope) would be deleted from the outer scope.
1635
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001636- Issue #2620: Overflow checking when allocating or reallocating memory
1637 was not always being done properly in some python types and extension
1638 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1639 all been updated to perform better checks and places in the code that
1640 would previously leak memory on the error path when such an allocation
1641 failed have been fixed.

1644-------
1645
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001646- Issue #3612: Added some missing basic types in ctypes.wintypes.
1647
Benjamin Petersone977ad42008-08-20 01:42:01 +00001648- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1649 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1650
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001651- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1652 version reported by these tools does not necessarily follow the python
1653 version numbering scheme, so the module is less strict when parsing it.
1654
Nick Coghlanf70385a2008-08-18 12:42:46 +00001655- Issue #2235: Added Py3k warnings for types which will become unhashable
1656 under the stricter __hash__ inheritance rules in 3.0. Several types
1657 which did not meet the rules for hash invariants and were already
1658 unhashable in 3.0 have now been explicitly flagged as unhashable in
1659 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1660 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1661
Brett Cannon88f801d2008-08-18 00:46:22 +00001662- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1663 imported into the module but exposed as part of the module's API.
1664
Brett Cannon7b96f072008-08-18 00:41:11 +00001665- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1666
Brett Cannon46225e72008-08-18 00:36:52 +00001667- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1668
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001669- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1670
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001671- Issue #3575: Incremental decoder's decode function now takes bytearray
1672 by using 's*' instead of 't#'.
1673
Jesus Cea585ad8a2009-07-02 15:37:21 +00001674- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001675 fails unicode conversion on 2nd parameter. (windows only)
1676
Facundo Batista94f243a2008-08-17 03:38:39 +00001677- Issue 2464. urllib2 now supports a malformation in the URL received
1678 in a redirect.
1679
Brett Cannonabe423e2008-08-16 21:47:07 +00001680- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001681 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001682
Facundo Batistaeb90b782008-08-16 14:44:07 +00001683- Issue #2776: fixed small issue when handling an URL with double slash
1684 after a 302 response in the case of not going through a proxy.
1685
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001686- Issue #2676: in the email package, content-type parsing was hanging on
1687 pathological input because of quadratic or exponential behaviour of a
1688 regular expression.
1689
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001690- Issue #3476: binary buffered reading through the new "io" library is now
1691 thread-safe.
1692
Brett Cannonbf3157b2008-08-14 05:00:03 +00001693- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1694 since mimetools itself is deprecated. Because modules are cached, all
1695 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1696
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001697- Issue #3134: shutil referenced undefined WindowsError symbol.
1698
Robert Schuppenies14646332008-08-10 11:01:53 +00001699- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1700 menu entries were not deleted.
1701
Brett Cannon83e81842008-08-09 23:30:55 +00001702- Copied the implementation of reduce() to _functools.reduce() to have a
1703 version that did not raise a DeprecationWarning under -3.
1704
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001705- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1706 a MemoryError rather than silently stop the iteration.
1707
Guido van Rossum59ce9012008-08-09 14:55:34 +00001708- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1709 to _sre.compile() will now be rejected. This should not affect anybody
1710 since the re.compile() function never generates invalid re-bytecode.
1711
Skip Montanaroa032bf42008-08-08 22:52:51 +00001712- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1713 upon first access it can be automatically initialized from the csv file if
1714 it wasn't initialized during instantiation.
1715
Brett Cannon3aa2a492008-08-06 22:28:09 +00001716- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1717 the reload() built-in has been removed.
1718
Brett Cannon7e30b672008-08-04 21:52:25 +00001719- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001720 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001721 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1722 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1723 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1724 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1725 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001726
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001727- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1728 raised an AttributeError.
1729
Benjamin Peterson01a24322008-07-28 23:35:27 +00001730- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001731 asking for a specific length. This problem only affected files opened
1732 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001733
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001734- Issue #3449: Update decimal module to use most recent specification
1735 (v. 1.68) and tests (v. 2.58) from IBM.
1736
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001737- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1738
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001739- Issue 1592: Improve error reporting when operations are attempted
1740 on a closed shelf.

1743
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001744- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1745
1746- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1747 invalid arguments.
1748
1749- Issue #3302: Fix several crashes when calling locale's gettext functions
1750 with None arguments.
1751
1752- Issue #3389: Allow resolving dotted names for handlers in logging
1753 configuration files.
1754
1755- Deprecate the sunaudio module for removal in Python 3.0.
1756
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001757- Issue #3394: zipfile.writestr sets external attributes when passed a
1758 file name rather than a ZipInfo instance, so files are extracted with
1759 mode 0600 rather than 000 under Unix.
1760
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001761- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1762 argument in python 2.5, this broke code that subclassed Popen to include its
1763 own poll method. Fixed my moving _deadstate to an _internal_poll method.
1764
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00001765Build

1771-------------
1772
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001773- Issue #2235: the C API function PyObject_HashNotImplemented and its
1774 interaction with the tp_hash slot (added in 2.6b2) are now documented
1775
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001776- Issue #643841: The language reference now provides more detailed
1777 coverage of the lookup process for special methods. The disclaimers
1778 regarding lack of coverage of new-style classes have also been
1779 removed, since the coverage is now fairly reasonable.

1788-----------------
1789
Georg Brandl3e483f62008-07-16 22:57:41 +00001790- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1791 its methods now allow for items objects that can be converted to
1792 an integer using operator.index().
1793
Mark Dickinson64b7e502008-07-16 09:40:03 +00001794- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1795 produced a ValueError instead of giving the correct float.
1796
Eric Smitha5fa5a22008-07-16 00:11:49 +00001797- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1798 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1799
Mark Dickinson7103aa42008-07-15 19:08:33 +00001800- Issue #3008: the float type has a new instance method 'float.hex'
1801 and a new class method 'float.fromhex' to convert floating-point
1802 numbers to and from hexadecimal strings, respectively.
1803
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001804- Issue #2235: __hash__ is once again inherited by default. To allow
1805 collections.Hashable to remain meaningful in the presence of the
1806 default hash implementation (object.__hash__), it is now possible
1807 to explicit block inheritance of hash by setting __hash__=None at
1808 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1809 level.
1810
Nick Coghlanb028f502008-07-13 14:52:36 +00001811- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1812 the parent module cannot be found while performing an absolute import.
1813 This means that an incorrectly defined __package__ attribute will
1814 now only prevent relative imports in that module rather than causing
1815 all imports from that module to fail.
1816
Nick Coghlan14ff9942008-07-08 14:21:42 +00001817- Issue #2517: Allow unicode messages in Exceptions again by correctly
1818 bypassing the instance dictionary when looking up __unicode__ on
1819 new-style classes.
1820
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001821- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1822 set to a custom object whose write() method happens to install
1823 another file in sys.stdout.
1824
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001825- Issue #3088: Corrected a race condition in classes derived from
1826 threading.local: the first member set by a thread could be saved in
1827 another thread's dictionary.
1828
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001829- Issue #3004: Minor change to slice.indices(): the start and stop
1830 arguments are now treated identically, making the behaviour easier
1831 to describe and understand. For example, slice(None, -10,
1832 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1833 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1834 10, -1).
1835
Georg Brandl278fc502008-07-19 12:46:12 +00001836- Issue #3219: Calling a function with repeated keyword arguments,
1837 f(a=2, a=23), would not cause a syntax error. This was a regression
1838 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001839
Georg Brandl278fc502008-07-19 12:46:12 +00001840- Issue #2862: Make int and float freelist management consistent with
1841 other freelists. Changes their CompactFreeList apis into
1842 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001843

1845-------
1846
Thomas Heller57adf222008-08-14 19:10:48 +00001847- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1848 api functions without holding the GIL, which could lead to a fatal
1849 error when they failed.
1850
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001851- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
1852
Jesse Noller7fb96402008-07-17 21:01:05 +00001853- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

Jesse Noller13e9d582008-07-16 14:32:36 +00001859- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1860 ForkingPickler.register() to resolve conflict with ctypes.
1861
Vinay Sajip51e65192008-07-18 09:01:10 +00001862- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001863
Thomas Heller880f5292008-07-15 19:39:38 +00001864- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1865 a valid dlerror() message.
1866
Thomas Heller2bad6572008-07-15 17:19:50 +00001867- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1868 incomplete structure was created.
1869
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001870- Issue #3339: dummy_thread.acquire() should not return None.
1871
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001872- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1873
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001874- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001875
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001876- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1877 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001878 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001879 content-length. The problem had been corrected in the 2.4 branch, but never

2287 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002288 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002289
2290 This is controlled by the configure argument ``--with-universal-archs``:
2291
2292 - ``--with-universal-archs=all``: install 4-way universal
2293
2294 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2295
2296 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2297
2298 This option should be used in combination with ``--enable-universalsdk=``.
2299
2300 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 +00002350- Issue #1631171: Re-implement the 'warnings' module in C (the
2351 original Python code has been kept as backup). This will allow for
2352 using the 'warning's machinery in such places as the parser where
2353 use of pure Python code is not possible. Both the ``showarning()``
2354 and ``formatwarning()`` gain an optional 'line' argument which is
2355 not called by default for backwards-compatibility reasons. Setting
2356 ``warnings.showwarning()`` to an implementation that lacks support
2357 for the ``line`` argument will raise a DeprecationWarning.

2381
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002382- The getpass module has been improved on Unix. It now uses /dev/tty
2383 by default and uses stderr instead of stdout. A GetPassWarning is
2384 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002399- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002400 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002420- Issue #2550: The approach used by client/server code for obtaining
2421 ports to listen on in network-oriented tests has been refined in an
2422 effort to facilitate running multiple instances of the entire
2423 regression test suite in parallel without issue.
2424 test_support.bind_port() has been fixed such that it will always
2425 return a unique port -- which wasn't always the case with the
2426 previous implementation, especially if socket options had been set
2427 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2428 new implementation of bind_port() will actually raise an exception
2429 if it is passed an AF_INET/SOCK_STREAM socket with either the
2430 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2431 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2432 the socket it's been passed. This currently only applies to
2433 Windows. This option prevents any other sockets from binding to the
2434 host/port we've bound to, thus removing the possibility of the
2435 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2436 when a second SOCK_STREAM socket binds and accepts to a host/port
2437 that's already been bound by another socket. The optional preferred
2438 port parameter to bind_port() has been removed. Under no
2439 circumstances should tests be hard coding ports!
2440
2441 test_support.find_unused_port() has also been introduced, which will
2442 pass a temporary socket object to bind_port() in order to obtain an
2443 unused port. The temporary socket object is then closed and
2444 deleted, and the port is returned. This method should only be used
2445 for obtaining an unused port in order to pass to an external program
2446 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2447 a parameter to a server-oriented class that doesn't give you direct
2448 access to the underlying socket used.
2449
2450 Finally, test_support.HOST has been introduced, which should be used
2451 for the host argument of any relevant socket calls (i.e. bind and
2452 connect).

2726Core and builtins
2727-----------------
2728
Fred Drakea8ee94b2008-03-01 02:45:07 +00002729- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002730 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002731
Georg Brandlad61bc82008-02-23 15:11:18 +00002732- Issue #2067: file.__exit__() now calls subclasses' close() method.
2733
2734- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002735
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002736- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002737 issue 215555 for a discussion.
2738
Eric Smitha73fbe72008-02-23 03:09:44 +00002739- Added the future_builtins module, which contains hex() and oct().
2740 These are the PEP 3127 version of these functions, designed to be
2741 compatible with the hex() and oct() builtins from Python 3.0. They
2742 differ slightly in their output formats from the existing, unchanged
2743 Python 2.6 builtins. The expected usage of the future_builtins
2744 module is:
2745 from future_builtins import hex, oct
2746
Eric Smith7ef40bf2008-02-20 23:34:22 +00002747- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2748 exponents for exponents with absolute value < 100. Follows C99
2749 standard. This is a change on Windows, which would use 3 digits.
2750 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2751 so that any alterations it does to the resulting string will be
2752 available in stringlib/formatter.h (for float.__format__).
2753
Eric Smith5a3c1352008-02-19 13:21:56 +00002754- Implemented PEP 3101, Advanced String Formatting. This adds a new
2755 builtin format(); a format() method for str and unicode; a
2756 __format__() method to object, str, unicode, int, long, float, and
2757 datetime; the class string.Formatter; and the C API
2758 PyObject_Format().
2759
Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Fixed several potential crashes, all caused by specially crafted
2761 __del__ methods exploiting objects in temporarily inconsistent
2762 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002763
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002764- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765 prevent a possible crash: an Abstract Base Class would try to access
2766 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002767
Georg Brandl3ee81df2008-05-17 18:14:43 +00002768- Fixed repr() and str() of complex numbers with infinity or nan as
2769 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002770
Georg Brandl3ee81df2008-05-17 18:14:43 +00002771- Clear all free lists during a gc.collect() of the highest generation
2772 in order to allow pymalloc to free more arenas. Python may give back
2773 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002774
Georg Brandl3ee81df2008-05-17 18:14:43 +00002775- Issue #2045: Fix an infinite recursion triggered when printing a
2776 subclass of collections.defaultdict, if its default_factory is set
2777 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002778
Christian Heimesf75dbef2008-02-08 00:11:31 +00002779- Fixed a minor memory leak in dictobject.c. The content of the free
2780 list was not freed on interpreter shutdown.
2781
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782- Limit free list of method and builtin function objects to 256
2783 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002784
Georg Brandl3ee81df2008-05-17 18:14:43 +00002785- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2786 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002787 to compact the internal free lists of pre-allocted ints and floats.
2788
Georg Brandl3ee81df2008-05-17 18:14:43 +00002789- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2790 calls. Python expected the return type int but the fork familie
2791 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002792
Georg Brandl3ee81df2008-05-17 18:14:43 +00002793- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2794 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002795
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2797 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002798
Georg Brandl3ee81df2008-05-17 18:14:43 +00002799- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2800 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002801
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2803 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002804
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805- Patch #1473257: generator objects gain a gi_code attribute. This is
2806 the same object as the func_code attribute of the function that
2807 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002808
Georg Brandl3ee81df2008-05-17 18:14:43 +00002809- Issue #1920: "while 0" statements were completely removed by the
2810 compiler, even in the presence of an "else" clause, which is
2811 supposed to be run when the condition is false. Now the compiler
2812 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002813
Guido van Rossumeead05f2008-01-24 18:21:02 +00002814- A few crashers fixed: weakref_in_del.py (issue #1377858);
2815 loosing_dict_ref.py (issue #1303614, test67.py);
2816 borrowed_ref_[34].py (not in tracker).
2817
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002818- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002819 suppressed while an extension is loaded by calling SetErrorMode in
2820 dynload_win.c. The error is still reported properly.
2821
Georg Brandl3ee81df2008-05-17 18:14:43 +00002822- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002823 several extension methods and modules do not work without unicode
2824 support.
2825
Georg Brandl26543b12008-01-21 18:36:51 +00002826- Issue #1882: when compiling code from a string, encoding cookies in the
2827 second line of code were not always recognized correctly.
2828
Georg Brandl14404b62008-01-19 19:27:05 +00002829- Issue #1679: "0x" was taken as a valid integer literal.
2830
Georg Brandl6caad7d2008-01-26 14:19:22 +00002831- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002832 added.
2833
Christian Heimesc94e2b52008-01-14 04:13:37 +00002834- sys.float_info / PyFloat_GetInfo: The floating point information
2835 object was converted from a dict to a specialized structseq object.
2836
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837- Patch #1816: Added sys.flags structseq. It exposes the status of
2838 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002839
Georg Brandl3ee81df2008-05-17 18:14:43 +00002840- Objects/structseq.c: Implemented new structseq representation. The
2841 patch makes structseqs (e.g. the return value of os.stat) more
2842 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002843
Georg Brandl3ee81df2008-05-17 18:14:43 +00002844- Patch #1700288: added a type attribute cache that caches method
2845 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002846
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002847- Bug #1776: __import__() no longer accepts filenames on any platform.
2848 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002849

2851
Georg Brandl3ee81df2008-05-17 18:14:43 +00002852- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2853 envvar and sys.dont_write_bytecode attribute. All these can be set
2854 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Improve some exception messages when Windows fails to load an
2857 extension module. Now we get for example '%1 is not a valid Win32
2858 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002859
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002862- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2863 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002864
Christian Heimes0a8143f2007-12-18 23:22:54 +00002865- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002866 and INF. float("nan"), float("inf") and float("-inf") now work on
2867 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002868
Georg Brandl3ee81df2008-05-17 18:14:43 +00002869- Compiler now generates simpler and faster code for dictionary
2870 literals. The oparg for BUILD_MAP now indicates an estimated
2871 dictionary size. There is a new opcode, STORE_MAP, for adding
2872 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002873
Georg Brandl3ee81df2008-05-17 18:14:43 +00002874- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002882- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002883 SystemError.
2884
Nick Coghlanef01d822007-12-03 12:55:17 +00002885- PEP 366: Allow explicit relative imports when executing modules
2886 inside packages with the -m switch via a new module level
2887 __package__ attribute.
2888
Georg Brandl3ee81df2008-05-17 18:14:43 +00002889- Issue #1402: Fix a crash on exit, when another thread is still
2890 running, and if the deallocation of its frames somehow calls the
2891 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002892

2902 file can now be directly executed by passing their name to the
2903 interpreter. The directory/zipfile is automatically inserted as the
2904 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002905
Georg Brandl3ee81df2008-05-17 18:14:43 +00002906- Issue #1265: Fix a problem with sys.settrace, if the tracing
2907 function uses a generator expression when at the same time the
2908 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002909
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002910- sets and frozensets now have an isdisjoint() method.
2911
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002912- optimize the performance of builtin.sum().
2913
Neal Norwitz44f326e2007-10-05 05:29:17 +00002914- Fix warnings found by the new version of the Coverity checker.
2915
Georg Brandl3ee81df2008-05-17 18:14:43 +00002916- The enumerate() builtin function is no longer bounded to sequences
2917 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2918 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002919
Georg Brandl3ee81df2008-05-17 18:14:43 +00002920- Issue #1686386: Tuple's tp_repr did not take into account the
2921 possibility of having a self-referential tuple, which is possible
2922 from C code. Nor did object's tp_str consider that a type's tp_str
2923 could do something that could lead to an inifinite recursion.
2924 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2925 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002926
Georg Brandl3ee81df2008-05-17 18:14:43 +00002927- Issue #1164: It was possible to trigger deadlock when using the
2928 'print' statement to write to a file since the GIL was not released
2929 as needed. Now PyObject_Print() does the right thing along with
2930 various tp_print implementations of the built-in types and those in
2931 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002932
Georg Brandl3ee81df2008-05-17 18:14:43 +00002933- Issue #1147: Exceptions were directly allowing string exceptions in
2934 their throw() method even though string exceptions no longer
2935 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002936
Georg Brandl3ee81df2008-05-17 18:14:43 +00002937- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002940- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002941 PyObject_Call() never calling back out to Python code to trigger
2942 recursion depth updates/checks. Required the creation of a static

Neal Norwitz0ac60192007-05-27 04:08:54 +00002960- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002961 __*__ attributes. (Some already existed, e.g., __doc__ and
2962 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002963
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002964- Add -3 option to the interpreter to warn about features that are

2969
Collin Winter62903052007-05-18 23:11:24 +00002970- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002971 "except E as target:". This is to provide forwards compatibility
2972 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002973
Brett Cannon229cee22007-05-05 01:34:02 +00002974- Deprecate BaseException.message as per PEP 352.
2975
Georg Brandl3ee81df2008-05-17 18:14:43 +00002976- Issue #1303614: don't expose object's __dict__ when the dict is

2978
Vinay Sajip8549ce32007-05-06 17:53:37 +00002979- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002980 setting a plain string, ie don't expand to single letter identifiers.
2981
Raymond Hettinger13936692007-04-11 18:40:58 +00002982- Request #1191699: Slices can now be pickled.
2983
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002984- Request #1193128: str.translate() now allows a None argument for

2992
Guido van Rossum143b5642007-03-23 04:58:42 +00002993- Bug #1683368: The object.__init__() and object.__new__() methods are
2994 now stricter in rejecting excess arguments. The only time when
2995 either allows excess arguments is when it is not overridden and the
2996 other one is. For backwards compatibility, when both are
2997 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002998 warning later). Also, type.__init__() insists on the same signature
2999 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003000
Georg Brandl3ee81df2008-05-17 18:14:43 +00003001- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3002 object to complex using its __complex__() method before falling back
3003 to the __float__() method. Therefore, the functions in the cmath
3004 module now can operate on objects that define a __complex__()
3005 method.

3022
Georg Brandl7b9c5552007-03-12 14:30:05 +00003023- Bug #1678647: write a newline after printing an exception in any
3024 case, even when converting the value to a string failed.
3025
Georg Brandl871f1bc2007-03-12 13:17:36 +00003026- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003027 its argument, if it exists. If not, it will work like before. This
3028 allows customizing the output of dir() in the presence of a
3029 __getattr__().

3039 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003040
Georg Brandlaa2321b2007-03-07 00:40:28 +00003041- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003042 makes the filenames the warning module prints much more sensible
3043 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003044

3057 sq_ass_slice instead of the sq_slice slot.
3058
Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- When printing an unraisable error, don't print exceptions. before

3688 incompatibility since it never made sense with ordinary subclasses
3689 -- the failure just occurred later, with a more cumbersome
3690 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003971- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3972 with RFC 3207 and forgets any knowledge obtained from the server not
3973 obtained from the TLS negotiation itself. Patch contributed by Bill
3974 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003975
Georg Brandl3ee81df2008-05-17 18:14:43 +00003976- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003977 that the SMTP.starttls() caller no longer needs to call ehlo()
3978 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003979 does not claim to support starttls. Adds the
3980 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4061 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4062 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004079 time so that opening a database previously created with the DB_DUP
4080 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4081 opens. Specifically: dictionary assignment to a DB object will
4082 replace all values for a given key when the database allows
4083 duplicate values. DB users should use DB.put(k, v) when they want
4084 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004085

4091 characters with ASCII value less than 32. Also, it correctly quotes
4092 dots only if they occur on a single line, as opposed to the previous
4093 behavior of quoting dots if they are the second character of any
4094 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004411- Makefile.pre.in(buildbottest): Run an optional script
4412 pybuildbot.identify to include some information about the build
4413 environment.

4417-----
4418
Georg Brandl3ee81df2008-05-17 18:14:43 +00004419- Unified naming convention for free lists and their limits. All free
4420 lists in Object/ are named ``free_list``, the counter ``numfree``
4421 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4422 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004423
Georg Brandl3ee81df2008-05-17 18:14:43 +00004424- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4425 to ``PyTuple_SetItem``, it can be used to populate a brand new
4426 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004427
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004428- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004429
Georg Brandl3ee81df2008-05-17 18:14:43 +00004430- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4431 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4432 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004433
4434- Patch #1720595: add T_BOOL to the range of structmember types.
4435
4436- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4437 ``PyFloat_GetInfo()`` to the float API.
4438
Georg Brandl3ee81df2008-05-17 18:14:43 +00004439- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4440 of w# format code incorrectly truncated the length to an int, even
4441 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4442 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004443
Georg Brandl3ee81df2008-05-17 18:14:43 +00004444- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4445 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004446
Georg Brandl3ee81df2008-05-17 18:14:43 +00004447- PEP 3123: Provide forward compatibility with Python 3.0, while
4448 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4449 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004450
Georg Brandl3ee81df2008-05-17 18:14:43 +00004451- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4452 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004453
4454- Patch #1733960: Allow T_LONGLONG to accept ints.
4455
4456- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4457
Christian Heimes000a0742008-01-03 22:16:32 +00004458- Added a new API function ``PyImport_ImportModuleNoBlock``.
4459
Georg Brandl6caad7d2008-01-26 14:19:22 +00004460- Bug #1637022: Prefix AST symbols with _Py_.
4461
4462- Fix some leftovers from the conversion from int to Py_ssize_t
4463 (relevant to strings and sequences of more than 2**31 items).
4464
4465- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4466 outside of pystate.c and should not be necessary.
4467
Georg Brandl3ee81df2008-05-17 18:14:43 +00004468- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4469 absolute imports. In earlier versions they might have used relative
4470 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004471
Georg Brandl3ee81df2008-05-17 18:14:43 +00004472- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4473 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004474
Georg Brandl3ee81df2008-05-17 18:14:43 +00004475- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4476 macro so it can be used as an expression.

4481
Georg Brandl3ee81df2008-05-17 18:14:43 +00004482- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4483 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4484 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4485 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004486
Georg Brandl3ee81df2008-05-17 18:14:43 +00004487- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
4488 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004500- Removed the macfs module. It had been deprecated since Python 2.5.
4501 This lead to the deprecation of macostools.touched() as it relied
4502 solely on macfs and was a no-op under OS X.
