1041 do an explicit seek to the end of file (so that e.g. tell() returns the
1042 file size rather than 0). This is consistent with the behaviour of the
1043 traditional 2.x file object.

1076
1077- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
1078 302 conformant loader) will now work correctly in most cases (they
1079 are still subject to the constraints that exist for all code running
1080 from inside a module loaded via a PEP 302 loader and attempting to

1239What's New in Python 2.6.1
1240==========================
1241
1242*Release date: 04-Dec-2008*
1243
1244Core and Builtins
1245-----------------
1246
1247- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1248 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1249 instead of throwing a MemoryError.
1250
1251- Issue #4367: Python would segfault during compiling when the unicodedata
1252 module couldn't be imported and \N escapes were present.
1253
1254- Issue #4348: Some bytearray methods returned that didn't cause any change to
1255 the bytearray, returned the same bytearray instead of a copy.
1256
1257- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1258
1259- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1260
1261- Issue #4048: The parser module now correctly validates relative imports.
1262
1263- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1264 exec statement.
1265
1266- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1267 method does not return iterators for the 4th and 5th items.
1268
1269- Issue #4209: Enabling unicode_literals and the print_function in the same
1270 __future__ import didn't work.
1271
1272- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1273 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1274 really executed because I cannot move to such directory on win2k)
1275
1276- Issue #4069: When set.remove(element) is used with a set element, the element
1277 is temporarily replaced with an equivalent frozenset. But the eventual
1278 KeyError would always report the empty frozenset([]) as the missing key. Now
1279 it correctly refers to the initial element.
1280
1281- Fixed C99 style comments in several files. Python is now C89 compatible
1282 again.
1283
1284Library
1285-------

Christian Heimes268be912008-11-28 11:03:48 +00001287- Issue #3741: DISTUTILS_USE_SDK set causes msvc9compiler.py to raise an

1430
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001431- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1432 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1433 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1434 ``printf`` function, whereas PyString_FromFormat has an independent
1435 implementation and uses "%zd" on all platforms for size_t values.
1436 This makes a difference on win64, where ``printf`` needs "%Id" to display
1437 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001454 was correctly parsed but parsing of subsequent arguments failed.
1455
Vinay Sajip35e3b032008-09-01 14:33:59 +00001456- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001457 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1458 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1459 when given a tuple of classes as second argument, were looking up
1460 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1461 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001597What's New in Python 2.6 beta 3?
1598================================
1599
Barry Warsaw07a4a382008-08-21 01:15:08 +00001600*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001601
1602Core and Builtins
1603-----------------
1604
Guido van Rossumf8402962008-08-20 15:01:50 +00001605- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1606 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1607 extensions do not automatically benefit from the class attribute
1608 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1609 to their tp_flags field if they care. This is a backwards
1610 compatibility feature; in 3.0, all types will use the cache by
1611 default.
1612
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001613- Keyword arguments can now follow starred arguments. (``f(a, *args,
1614 keyword=23)`` is now valid syntax.)
1615
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001616- ctypes function pointers that are COM methods have a boolean True
1617 value again.
1618
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001619- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1620 by denying s# to parse objects that have a releasebuffer procedure,
1621 and introducing s*.
1622
Georg Brandl1e13ea92008-08-11 09:07:59 +00001623- Issue #3537: Fix an assertion failure when an empty but presized dict
1624 object was stored in the freelist.
1625
Mark Dickinsonb6467572008-08-04 21:30:09 +00001626- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1627 ValueError consistently across platforms.
1628
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001629- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1630 (64bit Unix, for example), unichr() would truncate its argument and return
1631 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1632
Neal Norwitze7d8be82008-07-31 17:17:14 +00001633- Apply security patches from Apple.
1634
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001635- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1636 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1637
Antoine Pitrou92f82162008-07-25 22:22:08 +00001638- Issue #1819: function calls with several named parameters are now on
1639 average 35% faster (as measured by pybench).
1640
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001641- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1642 the python debugger steps into a class statement: the free variables (local
1643 variables defined in an outer scope) would be deleted from the outer scope.
1644
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001645- Issue #2620: Overflow checking when allocating or reallocating memory
1646 was not always being done properly in some python types and extension
1647 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1648 all been updated to perform better checks and places in the code that
1649 would previously leak memory on the error path when such an allocation
1650 failed have been fixed.
1651
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001652Library
1653-------
1654
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001655- Issue #3612: Added some missing basic types in ctypes.wintypes.
1656
Benjamin Petersone977ad42008-08-20 01:42:01 +00001657- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1658 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1659
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001660- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1661 version reported by these tools does not necessarily follow the python
1662 version numbering scheme, so the module is less strict when parsing it.
1663
Nick Coghlanf70385a2008-08-18 12:42:46 +00001664- Issue #2235: Added Py3k warnings for types which will become unhashable
1665 under the stricter __hash__ inheritance rules in 3.0. Several types
1666 which did not meet the rules for hash invariants and were already
1667 unhashable in 3.0 have now been explicitly flagged as unhashable in
1668 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1669 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1670
Brett Cannon88f801d2008-08-18 00:46:22 +00001671- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1672 imported into the module but exposed as part of the module's API.
1673
Brett Cannon7b96f072008-08-18 00:41:11 +00001674- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1675
Brett Cannon46225e72008-08-18 00:36:52 +00001676- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1677
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001678- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1679
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001680- Issue #3575: Incremental decoder's decode function now takes bytearray
1681 by using 's*' instead of 't#'.
1682
Jesus Cea585ad8a2009-07-02 15:37:21 +00001683- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001684 fails unicode conversion on 2nd parameter. (windows only)
1685
Facundo Batista94f243a2008-08-17 03:38:39 +00001686- Issue 2464. urllib2 now supports a malformation in the URL received
1687 in a redirect.
1688
Brett Cannonabe423e2008-08-16 21:47:07 +00001689- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001690 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001691
Facundo Batistaeb90b782008-08-16 14:44:07 +00001692- Issue #2776: fixed small issue when handling an URL with double slash
1693 after a 302 response in the case of not going through a proxy.
1694
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001695- Issue #2676: in the email package, content-type parsing was hanging on
1696 pathological input because of quadratic or exponential behaviour of a
1697 regular expression.
1698
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001699- Issue #3476: binary buffered reading through the new "io" library is now
1700 thread-safe.
1701
Brett Cannonbf3157b2008-08-14 05:00:03 +00001702- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1703 since mimetools itself is deprecated. Because modules are cached, all
1704 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1705
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001706- Issue #3134: shutil referenced undefined WindowsError symbol.
1707
Robert Schuppenies14646332008-08-10 11:01:53 +00001708- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1709 menu entries were not deleted.
1710
Brett Cannon83e81842008-08-09 23:30:55 +00001711- Copied the implementation of reduce() to _functools.reduce() to have a
1712 version that did not raise a DeprecationWarning under -3.
1713
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001714- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1715 a MemoryError rather than silently stop the iteration.
1716
Guido van Rossum59ce9012008-08-09 14:55:34 +00001717- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1718 to _sre.compile() will now be rejected. This should not affect anybody
1719 since the re.compile() function never generates invalid re-bytecode.
1720
Skip Montanaroa032bf42008-08-08 22:52:51 +00001721- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1722 upon first access it can be automatically initialized from the csv file if
1723 it wasn't initialized during instantiation.
1724
Brett Cannon3aa2a492008-08-06 22:28:09 +00001725- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1726 the reload() built-in has been removed.
1727
Brett Cannon7e30b672008-08-04 21:52:25 +00001728- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001729 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001730 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1731 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1732 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1733 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1734 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001735
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001736- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1737 raised an AttributeError.
1738
Benjamin Peterson01a24322008-07-28 23:35:27 +00001739- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001740 asking for a specific length. This problem only affected files opened
1741 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001742
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001743- Issue #3449: Update decimal module to use most recent specification
1744 (v. 1.68) and tests (v. 2.58) from IBM.
1745
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001746- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1747
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001748- Issue 1592: Improve error reporting when operations are attempted
1749 on a closed shelf.

1752
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001753- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1754
1755- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1756 invalid arguments.
1757
1758- Issue #3302: Fix several crashes when calling locale's gettext functions
1759 with None arguments.
1760
1761- Issue #3389: Allow resolving dotted names for handlers in logging
1762 configuration files.
1763
1764- Deprecate the sunaudio module for removal in Python 3.0.
1765
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001766- Issue #3394: zipfile.writestr sets external attributes when passed a
1767 file name rather than a ZipInfo instance, so files are extracted with
1768 mode 0600 rather than 000 under Unix.
1769
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001770- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1771 argument in python 2.5, this broke code that subclassed Popen to include its
1772 own poll method. Fixed my moving _deadstate to an _internal_poll method.
1773
Martin v. Löwis8dbf3642008-08-01 14:10:26 +00001774Build
1775-----

1780-------------
1781
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001782- Issue #2235: the C API function PyObject_HashNotImplemented and its
1783 interaction with the tp_hash slot (added in 2.6b2) are now documented
1784
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001785- Issue #643841: The language reference now provides more detailed
1786 coverage of the lookup process for special methods. The disclaimers
1787 regarding lack of coverage of new-style classes have also been
1788 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001791What's New in Python 2.6 beta 2?
1792================================
1793
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001794*Release date: 17-Jul-2008*
1795
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001796Core and Builtins
1797-----------------
1798
Georg Brandl3e483f62008-07-16 22:57:41 +00001799- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1800 its methods now allow for items objects that can be converted to
1801 an integer using operator.index().
1802
Mark Dickinson64b7e502008-07-16 09:40:03 +00001803- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1804 produced a ValueError instead of giving the correct float.
1805
Eric Smitha5fa5a22008-07-16 00:11:49 +00001806- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1807 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1808
Mark Dickinson7103aa42008-07-15 19:08:33 +00001809- Issue #3008: the float type has a new instance method 'float.hex'
1810 and a new class method 'float.fromhex' to convert floating-point
1811 numbers to and from hexadecimal strings, respectively.
1812
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001813- Issue #2235: __hash__ is once again inherited by default. To allow
1814 collections.Hashable to remain meaningful in the presence of the
1815 default hash implementation (object.__hash__), it is now possible
1816 to explicit block inheritance of hash by setting __hash__=None at
1817 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1818 level.
1819
Nick Coghlanb028f502008-07-13 14:52:36 +00001820- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1821 the parent module cannot be found while performing an absolute import.
1822 This means that an incorrectly defined __package__ attribute will
1823 now only prevent relative imports in that module rather than causing
1824 all imports from that module to fail.
1825
Nick Coghlan14ff9942008-07-08 14:21:42 +00001826- Issue #2517: Allow unicode messages in Exceptions again by correctly
1827 bypassing the instance dictionary when looking up __unicode__ on
1828 new-style classes.
1829
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001830- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1831 set to a custom object whose write() method happens to install
1832 another file in sys.stdout.
1833
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001834- Issue #3088: Corrected a race condition in classes derived from
1835 threading.local: the first member set by a thread could be saved in
1836 another thread's dictionary.
1837
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001838- Issue #3004: Minor change to slice.indices(): the start and stop
1839 arguments are now treated identically, making the behaviour easier
1840 to describe and understand. For example, slice(None, -10,
1841 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1842 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1843 10, -1).
1844
Georg Brandl278fc502008-07-19 12:46:12 +00001845- Issue #3219: Calling a function with repeated keyword arguments,
1846 f(a=2, a=23), would not cause a syntax error. This was a regression
1847 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001848
Georg Brandl278fc502008-07-19 12:46:12 +00001849- Issue #2862: Make int and float freelist management consistent with
1850 other freelists. Changes their CompactFreeList apis into
1851 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001852

1854-------
1855
Thomas Heller57adf222008-08-14 19:10:48 +00001856- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1857 api functions without holding the GIL, which could lead to a fatal
1858 error when they failed.
1859
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001860- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001868- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1869 ForkingPickler.register() to resolve conflict with ctypes.
1870
Vinay Sajip51e65192008-07-18 09:01:10 +00001871- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

1874 a valid dlerror() message.
1875
Thomas Heller2bad6572008-07-15 17:19:50 +00001876- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1877 incomplete structure was created.
1878
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001879- Issue #3339: dummy_thread.acquire() should not return None.
1880

Georg Brandl5cc774e2008-06-11 20:28:06 +00002297 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002298
2299 This is controlled by the configure argument ``--with-universal-archs``:
2300
2301 - ``--with-universal-archs=all``: install 4-way universal
2302
2303 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2304
2305 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2306

Georg Brandl3ee81df2008-05-17 18:14:43 +00002359- Issue #1631171: Re-implement the 'warnings' module in C (the
2360 original Python code has been kept as backup). This will allow for
2361 using the 'warning's machinery in such places as the parser where
2362 use of pure Python code is not possible. Both the ``showarning()``
2363 and ``formatwarning()`` gain an optional 'line' argument which is
2364 not called by default for backwards-compatibility reasons. Setting
2365 ``warnings.showwarning()`` to an implementation that lacks support
2366 for the ``line`` argument will raise a DeprecationWarning.

2390
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002391- The getpass module has been improved on Unix. It now uses /dev/tty
2392 by default and uses stderr instead of stdout. A GetPassWarning is
2393 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002408- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002409 extension modules between 32 and 64 bit platforms. See the distutls

2431 effort to facilitate running multiple instances of the entire
2432 regression test suite in parallel without issue.
2433 test_support.bind_port() has been fixed such that it will always
2434 return a unique port -- which wasn't always the case with the
2435 previous implementation, especially if socket options had been set
2436 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2437 new implementation of bind_port() will actually raise an exception
2438 if it is passed an AF_INET/SOCK_STREAM socket with either the
2439 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2440 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2441 the socket it's been passed. This currently only applies to
2442 Windows. This option prevents any other sockets from binding to the
2443 host/port we've bound to, thus removing the possibility of the
2444 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2445 when a second SOCK_STREAM socket binds and accepts to a host/port
2446 that's already been bound by another socket. The optional preferred
2447 port parameter to bind_port() has been removed. Under no
2448 circumstances should tests be hard coding ports!
2449
2450 test_support.find_unused_port() has also been introduced, which will
2451 pass a temporary socket object to bind_port() in order to obtain an
2452 unused port. The temporary socket object is then closed and
2453 deleted, and the port is returned. This method should only be used
2454 for obtaining an unused port in order to pass to an external program
2455 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2456 a parameter to a server-oriented class that doesn't give you direct
2457 access to the underlying socket used.
2458
2459 Finally, test_support.HOST has been introduced, which should be used
2460 for the host argument of any relevant socket calls (i.e. bind and
2461 connect).

2463 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002464 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002465 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2466 test_asynchat and test_socket_ssl.
2467
Georg Brandl3ee81df2008-05-17 18:14:43 +00002468 It is now possible for multiple instances of the regression test
2469 suite to run in parallel without issue.

2735Core and builtins
2736-----------------
2737
Fred Drakea8ee94b2008-03-01 02:45:07 +00002738- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002739 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002740
Georg Brandlad61bc82008-02-23 15:11:18 +00002741- Issue #2067: file.__exit__() now calls subclasses' close() method.
2742
2743- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002744
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002745- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002746 issue 215555 for a discussion.
2747
Eric Smitha73fbe72008-02-23 03:09:44 +00002748- Added the future_builtins module, which contains hex() and oct().
2749 These are the PEP 3127 version of these functions, designed to be
2750 compatible with the hex() and oct() builtins from Python 3.0. They
2751 differ slightly in their output formats from the existing, unchanged
2752 Python 2.6 builtins. The expected usage of the future_builtins
2753 module is:
2754 from future_builtins import hex, oct
2755
Eric Smith7ef40bf2008-02-20 23:34:22 +00002756- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2757 exponents for exponents with absolute value < 100. Follows C99
2758 standard. This is a change on Windows, which would use 3 digits.
2759 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2760 so that any alterations it does to the resulting string will be
2761 available in stringlib/formatter.h (for float.__format__).
2762
Eric Smith5a3c1352008-02-19 13:21:56 +00002763- Implemented PEP 3101, Advanced String Formatting. This adds a new
2764 builtin format(); a format() method for str and unicode; a
2765 __format__() method to object, str, unicode, int, long, float, and
2766 datetime; the class string.Formatter; and the C API
2767 PyObject_Format().
2768
Georg Brandl3ee81df2008-05-17 18:14:43 +00002769- Fixed several potential crashes, all caused by specially crafted
2770 __del__ methods exploiting objects in temporarily inconsistent
2771 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002772
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002773- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002774 prevent a possible crash: an Abstract Base Class would try to access
2775 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002776
Georg Brandl3ee81df2008-05-17 18:14:43 +00002777- Fixed repr() and str() of complex numbers with infinity or nan as
2778 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002779
Georg Brandl3ee81df2008-05-17 18:14:43 +00002780- Clear all free lists during a gc.collect() of the highest generation
2781 in order to allow pymalloc to free more arenas. Python may give back
2782 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002783
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784- Issue #2045: Fix an infinite recursion triggered when printing a
2785 subclass of collections.defaultdict, if its default_factory is set
2786 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002787
Christian Heimesf75dbef2008-02-08 00:11:31 +00002788- Fixed a minor memory leak in dictobject.c. The content of the free
2789 list was not freed on interpreter shutdown.
2790
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Limit free list of method and builtin function objects to 256
2792 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002793
Georg Brandl3ee81df2008-05-17 18:14:43 +00002794- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2795 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002796 to compact the internal free lists of pre-allocted ints and floats.
2797
Georg Brandl3ee81df2008-05-17 18:14:43 +00002798- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2799 calls. Python expected the return type int but the fork familie
2800 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002801
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2803 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002804
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2806 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2809 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002810
Georg Brandl3ee81df2008-05-17 18:14:43 +00002811- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2812 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002813
Georg Brandl3ee81df2008-05-17 18:14:43 +00002814- Patch #1473257: generator objects gain a gi_code attribute. This is
2815 the same object as the func_code attribute of the function that
2816 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002817
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818- Issue #1920: "while 0" statements were completely removed by the
2819 compiler, even in the presence of an "else" clause, which is
2820 supposed to be run when the condition is false. Now the compiler
2821 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002822
Guido van Rossumeead05f2008-01-24 18:21:02 +00002823- A few crashers fixed: weakref_in_del.py (issue #1377858);
2824 loosing_dict_ref.py (issue #1303614, test67.py);
2825 borrowed_ref_[34].py (not in tracker).
2826
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002827- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002828 suppressed while an extension is loaded by calling SetErrorMode in
2829 dynload_win.c. The error is still reported properly.
2830
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002832 several extension methods and modules do not work without unicode
2833 support.
2834
Georg Brandl26543b12008-01-21 18:36:51 +00002835- Issue #1882: when compiling code from a string, encoding cookies in the
2836 second line of code were not always recognized correctly.
2837
Georg Brandl14404b62008-01-19 19:27:05 +00002838- Issue #1679: "0x" was taken as a valid integer literal.
2839
Georg Brandl6caad7d2008-01-26 14:19:22 +00002840- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002841 added.
2842
Christian Heimesc94e2b52008-01-14 04:13:37 +00002843- sys.float_info / PyFloat_GetInfo: The floating point information
2844 object was converted from a dict to a specialized structseq object.
2845
Georg Brandl3ee81df2008-05-17 18:14:43 +00002846- Patch #1816: Added sys.flags structseq. It exposes the status of
2847 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- Objects/structseq.c: Implemented new structseq representation. The
2850 patch makes structseqs (e.g. the return value of os.stat) more
2851 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002852
Georg Brandl3ee81df2008-05-17 18:14:43 +00002853- Patch #1700288: added a type attribute cache that caches method
2854 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002855
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002856- Bug #1776: __import__() no longer accepts filenames on any platform.
2857 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002858
Georg Brandlaed6c662008-01-07 17:25:53 +00002859- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2860
Georg Brandl3ee81df2008-05-17 18:14:43 +00002861- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2862 envvar and sys.dont_write_bytecode attribute. All these can be set
2863 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002864
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Improve some exception messages when Windows fails to load an
2866 extension module. Now we get for example '%1 is not a valid Win32
2867 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002868
Georg Brandl3ee81df2008-05-17 18:14:43 +00002869- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2872 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002873
Christian Heimes0a8143f2007-12-18 23:22:54 +00002874- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002875 and INF. float("nan"), float("inf") and float("-inf") now work on
2876 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002877
Georg Brandl3ee81df2008-05-17 18:14:43 +00002878- Compiler now generates simpler and faster code for dictionary
2879 literals. The oparg for BUILD_MAP now indicates an estimated
2880 dictionary size. There is a new opcode, STORE_MAP, for adding
2881 entries to the dictionary.

2899 running, and if the deallocation of its frames somehow calls the
2900 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002901

2911 file can now be directly executed by passing their name to the
2912 interpreter. The directory/zipfile is automatically inserted as the
2913 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002914
Georg Brandl3ee81df2008-05-17 18:14:43 +00002915- Issue #1265: Fix a problem with sys.settrace, if the tracing
2916 function uses a generator expression when at the same time the
2917 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002918
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002919- sets and frozensets now have an isdisjoint() method.
2920
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002921- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00002923- Fix warnings found by the new version of the Coverity checker.
2924
Georg Brandl3ee81df2008-05-17 18:14:43 +00002925- The enumerate() builtin function is no longer bounded to sequences
2926 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2927 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002928
Georg Brandl3ee81df2008-05-17 18:14:43 +00002929- Issue #1686386: Tuple's tp_repr did not take into account the
2930 possibility of having a self-referential tuple, which is possible
2931 from C code. Nor did object's tp_str consider that a type's tp_str
2932 could do something that could lead to an inifinite recursion.
2933 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2934 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002935
Georg Brandl3ee81df2008-05-17 18:14:43 +00002936- Issue #1164: It was possible to trigger deadlock when using the
2937 'print' statement to write to a file since the GIL was not released
2938 as needed. Now PyObject_Print() does the right thing along with
2939 various tp_print implementations of the built-in types and those in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002942- Issue #1147: Exceptions were directly allowing string exceptions in
2943 their throw() method even though string exceptions no longer
2944 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002945
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946- Issue #1096: Prevent a segfault from getting the repr of a very
2947 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002948
Brett Cannon1e534b52007-09-07 04:18:30 +00002949- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002950 PyObject_Call() never calling back out to Python code to trigger
2951 recursion depth updates/checks. Required the creation of a static
2952 RuntimeError instance in case normalizing an exception put the
2953 recursion check value past its limit. Fixes crashers
2954 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002969- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970 __*__ attributes. (Some already existed, e.g., __doc__ and
2971 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002972
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002973- Add -3 option to the interpreter to warn about features that are

2977 calls.
2978
Collin Winter62903052007-05-18 23:11:24 +00002979- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002980 "except E as target:". This is to provide forwards compatibility
2981 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002982
Brett Cannon229cee22007-05-05 01:34:02 +00002983- Deprecate BaseException.message as per PEP 352.
2984
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002986 inherited from a builtin base.
2987
Vinay Sajip8549ce32007-05-06 17:53:37 +00002988- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002989 setting a plain string, ie don't expand to single letter identifiers.
2990
Raymond Hettinger13936692007-04-11 18:40:58 +00002991- Request #1191699: Slices can now be pickled.
2992
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002993- Request #1193128: str.translate() now allows a None argument for
2994 translations that only remove characters without re-mapping the
2995 remaining characters.
2996
Georg Brandl5cb76c12007-03-21 09:00:39 +00002997- Patch #1682205: a TypeError while unpacking an iterable is no longer
2998 masked by a generic one with the message "unpack non-sequence".
2999
Neal Norwitzaa754b72007-03-21 06:39:48 +00003000- Remove unused file Python/fmod.c.
3001
Guido van Rossum143b5642007-03-23 04:58:42 +00003002- Bug #1683368: The object.__init__() and object.__new__() methods are
3003 now stricter in rejecting excess arguments. The only time when
3004 either allows excess arguments is when it is not overridden and the
3005 other one is. For backwards compatibility, when both are
3006 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003007 warning later). Also, type.__init__() insists on the same signature
3008 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003009
Georg Brandl3ee81df2008-05-17 18:14:43 +00003010- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3011 object to complex using its __complex__() method before falling back
3012 to the __float__() method. Therefore, the functions in the cmath
3013 module now can operate on objects that define a __complex__()
3014 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003015
Georg Brandl3ee81df2008-05-17 18:14:43 +00003016- Patch #1623563: allow __class__ assignment for classes with
3017 __slots__. The old and the new class are still required to have the
3018 same slot names.

3025 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003026
Georg Brandl3ee81df2008-05-17 18:14:43 +00003027- Patch #1680015: Don't modify __slots__ tuple if it contains an

3031
Georg Brandl7b9c5552007-03-12 14:30:05 +00003032- Bug #1678647: write a newline after printing an exception in any
3033 case, even when converting the value to a string failed.
3034
Georg Brandl871f1bc2007-03-12 13:17:36 +00003035- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003036 its argument, if it exists. If not, it will work like before. This
3037 allows customizing the output of dir() in the presence of a
3038 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003039
Collin Winter276887b2007-03-12 16:11:39 +00003040- Patch #922167: Python no longer segfaults when faced with infinitely
3041 self-recursive reload() calls (as reported by bug #742342).
3042

3047 parthensized forms. This means complex(repr(x)) now works instead of
3048 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003049
Georg Brandlaa2321b2007-03-07 00:40:28 +00003050- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003051 makes the filenames the warning module prints much more sensible
3052 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003053
Georg Brandl49aafc92007-03-07 00:34:46 +00003054- Variant of patch #697613: don't exit the interpreter on a SystemExit
3055 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003056 variable is given, but break into the interactive interpreter just
3057 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003065- Patch #1674228: when assigning a slice (old-style), check for the
3066 sq_ass_slice instead of the sq_slice slot.
3067
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068- When printing an unraisable error, don't print exceptions. before
3069 the name. This duplicates the behavior whening normally printing
3070 exceptions.

3079 created a weakref on itself during a __del__ call for new-style
3080 classes (classic classes still have the bug).

3679 Python would crash instead of raising an error.
3680
Thomas Hellerc2f77252007-03-09 19:21:28 +00003681- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
3682 returned string up to the first NUL character.

3693
Georg Brandl3ee81df2008-05-17 18:14:43 +00003694- unittest now verifies more of its assumptions. In particular,
3695 TestCase and TestSuite subclasses (not instances) are no longer
3696 accepted in TestSuite.addTest(). This should cause no
3697 incompatibility since it never made sense with ordinary subclasses
3698 -- the failure just occurred later, with a more cumbersome
3699 exception.

3983 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003984
Georg Brandl3ee81df2008-05-17 18:14:43 +00003985- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003986 that the SMTP.starttls() caller no longer needs to call ehlo()
3987 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003988 does not claim to support starttls. Adds the
3989 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004088 time so that opening a database previously created with the DB_DUP
4089 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4090 opens. Specifically: dictionary assignment to a DB object will
4091 replace all values for a given key when the database allows
4092 duplicate values. DB users should use DB.put(k, v) when they want
4093 to store duplicates; not DB[k] = v.

4100 characters with ASCII value less than 32. Also, it correctly quotes
4101 dots only if they occur on a single line, as opposed to the previous
4102 behavior of quoting dots if they are the second character of any
4103 line.

4426-----
4427
Georg Brandl3ee81df2008-05-17 18:14:43 +00004428- Unified naming convention for free lists and their limits. All free
4429 lists in Object/ are named ``free_list``, the counter ``numfree``
4430 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4431 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004432
Georg Brandl3ee81df2008-05-17 18:14:43 +00004433- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4434 to ``PyTuple_SetItem``, it can be used to populate a brand new
4435 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004436
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004437- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004439- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4440 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4441 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004442
4443- Patch #1720595: add T_BOOL to the range of structmember types.
4444
4445- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4446 ``PyFloat_GetInfo()`` to the float API.
4447
Georg Brandl3ee81df2008-05-17 18:14:43 +00004448- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4449 of w# format code incorrectly truncated the length to an int, even
4450 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4451 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004452
Georg Brandl3ee81df2008-05-17 18:14:43 +00004453- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4454 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004455
Georg Brandl3ee81df2008-05-17 18:14:43 +00004456- PEP 3123: Provide forward compatibility with Python 3.0, while
4457 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4458 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004459
Georg Brandl3ee81df2008-05-17 18:14:43 +00004460- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4461 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004462
4463- Patch #1733960: Allow T_LONGLONG to accept ints.
4464

4470
4471- Fix some leftovers from the conversion from int to Py_ssize_t
4472 (relevant to strings and sequences of more than 2**31 items).
4473
4474- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4475 outside of pystate.c and should not be necessary.
4476
Georg Brandl3ee81df2008-05-17 18:14:43 +00004477- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4478 absolute imports. In earlier versions they might have used relative
4479 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004480
Georg Brandl3ee81df2008-05-17 18:14:43 +00004481- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4482 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004483
Georg Brandl3ee81df2008-05-17 18:14:43 +00004484- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4485 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004491- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4492 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4493 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4494 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004495
Georg Brandl3ee81df2008-05-17 18:14:43 +00004496- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004509- Removed the macfs module. It had been deprecated since Python 2.5.
4510 This lead to the deprecation of macostools.touched() as it relied
4511 solely on macfs and was a no-op under OS X.
