Vinay Sajip03d327d2009-04-16 19:14:09 +0000313- Issue #5177: Multiprocessing's SocketListener class now uses
Jesse Nollerb48cfa62009-03-30 16:19:10 +0000314 socket.SO_REUSEADDR on all connections so that the user no longer needs
315 to wait 120 seconds for the socket to expire.
316

325 forever on incomplete input. That caused tarfile.open() to hang when used
326 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
327 partial bzip2 compressed data.
328
Benjamin Peterson373498f2009-03-22 17:49:21 +0000329- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

372 which inherited from numbers.py which did not have __slots__ defined. The

377
Jesse Nollere6bab482009-03-30 16:11:16 +0000378- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks
Barry Warsaw90971e02009-04-07 01:54:02 +0000379 for *nix machines for negative handles and large int handles. Without this
380 check it is possible to segfault the interpreter.

Antoine Pitrou19fec8b2009-01-21 00:56:37 +0000418- Issue #5008: When a file is opened in append mode with the new IO library,
419 do an explicit seek to the end of file (so that e.g. tell() returns the
420 file size rather than 0). This is consistent with the behaviour of the
421 traditional 2.x file object.
422
Amaury Forgeot d'Arc0293c802009-01-17 16:46:35 +0000423- Issue #3997: zipfiles generated with more than 65536 files could not be

455- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
456 302 conformant loader) will now work correctly in most cases (they
457 are still subject to the constraints that exist for all code running
458 from inside a module loaded via a PEP 302 loader and attempting to

620What's New in Python 2.6.1
621==========================
622
623*Release date: 04-Dec-2008*
624
625Core and Builtins
626-----------------
627
628- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
629 interpreter to abort ("Fatal Python error: Could not reset the stack!")
630 instead of throwing a MemoryError.
631
632- Issue #4367: Python would segfault during compiling when the unicodedata
633 module couldn't be imported and \N escapes were present.
634
635- Issue #4348: Some bytearray methods returned that didn't cause any change to
636 the bytearray, returned the same bytearray instead of a copy.
637
638- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
639
640- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
641
642- Issue #4048: The parser module now correctly validates relative imports.
643
644- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
645 exec statement.
646
647- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
648 method does not return iterators for the 4th and 5th items.
649
650- Issue #4209: Enabling unicode_literals and the print_function in the same
651 __future__ import didn't work.
652
653- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
654 returned a path longer than MAX_PATH. (But It's doubtful this code path is
655 really executed because I cannot move to such directory on win2k)
656
657- Issue #4069: When set.remove(element) is used with a set element, the element
658 is temporarily replaced with an equivalent frozenset. But the eventual
659 KeyError would always report the empty frozenset([]) as the missing key. Now
660 it correctly refers to the initial element.
661
662- Fixed C99 style comments in several files. Python is now C89 compatible
663 again.
664

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000810- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
811
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000812- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
813 PyString_FromFormat or PyErr_Format to display size_t values. The macro
814 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
815 ``printf`` function, whereas PyString_FromFormat has an independent
816 implementation and uses "%zd" on all platforms for size_t values.
817 This makes a difference on win64, where ``printf`` needs "%Id" to display
818 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000835 was correctly parsed but parsing of subsequent arguments failed.
836
Vinay Sajip35e3b032008-09-01 14:33:59 +0000837- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000838 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
839 mechanism. In the process, fix a bug where isinstance() and issubclass(),
840 when given a tuple of classes as second argument, were looking up
841 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
842 type object.

983Core and Builtins
984-----------------
985
Guido van Rossumf8402962008-08-20 15:01:50 +0000986- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
987 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
988 extensions do not automatically benefit from the class attribute
989 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
990 to their tp_flags field if they care. This is a backwards
991 compatibility feature; in 3.0, all types will use the cache by
992 default.
993
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000994- Keyword arguments can now follow starred arguments. (``f(a, *args,
995 keyword=23)`` is now valid syntax.)
996
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000997- ctypes function pointers that are COM methods have a boolean True
998 value again.
999
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001000- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1001 by denying s# to parse objects that have a releasebuffer procedure,
1002 and introducing s*.
1003
Georg Brandl1e13ea92008-08-11 09:07:59 +00001004- Issue #3537: Fix an assertion failure when an empty but presized dict
1005 object was stored in the freelist.
1006
Mark Dickinsonb6467572008-08-04 21:30:09 +00001007- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1008 ValueError consistently across platforms.
1009
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001010- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1011 (64bit Unix, for example), unichr() would truncate its argument and return
1012 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1013
Neal Norwitze7d8be82008-07-31 17:17:14 +00001014- Apply security patches from Apple.
1015
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001016- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1017 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1018
Antoine Pitrou92f82162008-07-25 22:22:08 +00001019- Issue #1819: function calls with several named parameters are now on
1020 average 35% faster (as measured by pybench).
1021
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001022- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1023 the python debugger steps into a class statement: the free variables (local
1024 variables defined in an outer scope) would be deleted from the outer scope.
1025
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001026- Issue #2620: Overflow checking when allocating or reallocating memory
1027 was not always being done properly in some python types and extension
1028 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1029 all been updated to perform better checks and places in the code that
1030 would previously leak memory on the error path when such an allocation
1031 failed have been fixed.

1034-------
1035
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001036- Issue #3612: Added some missing basic types in ctypes.wintypes.
1037
Benjamin Petersone977ad42008-08-20 01:42:01 +00001038- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1039 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1040
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001041- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1042 version reported by these tools does not necessarily follow the python
1043 version numbering scheme, so the module is less strict when parsing it.
1044
Nick Coghlanf70385a2008-08-18 12:42:46 +00001045- Issue #2235: Added Py3k warnings for types which will become unhashable
1046 under the stricter __hash__ inheritance rules in 3.0. Several types
1047 which did not meet the rules for hash invariants and were already
1048 unhashable in 3.0 have now been explicitly flagged as unhashable in
1049 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1050 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1051
Brett Cannon88f801d2008-08-18 00:46:22 +00001052- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1053 imported into the module but exposed as part of the module's API.
1054
Brett Cannon7b96f072008-08-18 00:41:11 +00001055- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1056
Brett Cannon46225e72008-08-18 00:36:52 +00001057- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1058
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001059- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1060
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001061- Issue #3575: Incremental decoder's decode function now takes bytearray
1062 by using 's*' instead of 't#'.
1063
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001064- Issue #2222: Fixed reference leak when occured os.rename()
1065 fails unicode conversion on 2nd parameter. (windows only)
1066
Facundo Batista94f243a2008-08-17 03:38:39 +00001067- Issue 2464. urllib2 now supports a malformation in the URL received
1068 in a redirect.
1069
Brett Cannonabe423e2008-08-16 21:47:07 +00001070- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001071 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001072
Facundo Batistaeb90b782008-08-16 14:44:07 +00001073- Issue #2776: fixed small issue when handling an URL with double slash
1074 after a 302 response in the case of not going through a proxy.
1075
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001076- Issue #2676: in the email package, content-type parsing was hanging on
1077 pathological input because of quadratic or exponential behaviour of a
1078 regular expression.
1079
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001080- Issue #3476: binary buffered reading through the new "io" library is now
1081 thread-safe.
1082
Brett Cannonbf3157b2008-08-14 05:00:03 +00001083- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1084 since mimetools itself is deprecated. Because modules are cached, all
1085 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1086
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001087- Issue #3134: shutil referenced undefined WindowsError symbol.
1088
Robert Schuppenies14646332008-08-10 11:01:53 +00001089- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1090 menu entries were not deleted.
1091
Brett Cannon83e81842008-08-09 23:30:55 +00001092- Copied the implementation of reduce() to _functools.reduce() to have a
1093 version that did not raise a DeprecationWarning under -3.
1094
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001095- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1096 a MemoryError rather than silently stop the iteration.
1097
Guido van Rossum59ce9012008-08-09 14:55:34 +00001098- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1099 to _sre.compile() will now be rejected. This should not affect anybody
1100 since the re.compile() function never generates invalid re-bytecode.
1101
Skip Montanaroa032bf42008-08-08 22:52:51 +00001102- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1103 upon first access it can be automatically initialized from the csv file if
1104 it wasn't initialized during instantiation.
1105
Brett Cannon3aa2a492008-08-06 22:28:09 +00001106- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1107 the reload() built-in has been removed.
1108
Brett Cannon7e30b672008-08-04 21:52:25 +00001109- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001110 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001111 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1112 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1113 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1114 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1115 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001116
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001117- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1118 raised an AttributeError.
1119
Benjamin Peterson01a24322008-07-28 23:35:27 +00001120- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001121 asking for a specific length. This problem only affected files opened
1122 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001123
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001124- Issue #3449: Update decimal module to use most recent specification
1125 (v. 1.68) and tests (v. 2.58) from IBM.
1126
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001127- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1128
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001129- Issue 1592: Improve error reporting when operations are attempted
1130 on a closed shelf.

1135
1136- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1137 invalid arguments.
1138
1139- Issue #3302: Fix several crashes when calling locale's gettext functions
1140 with None arguments.
1141
1142- Issue #3389: Allow resolving dotted names for handlers in logging
1143 configuration files.
1144
1145- Deprecate the sunaudio module for removal in Python 3.0.
1146
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001147- Issue #3394: zipfile.writestr sets external attributes when passed a
1148 file name rather than a ZipInfo instance, so files are extracted with
1149 mode 0600 rather than 000 under Unix.
1150
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001151- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1152 argument in python 2.5, this broke code that subclassed Popen to include its
1153 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1161-------------
1162
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001163- Issue #2235: the C API function PyObject_HashNotImplemented and its
1164 interaction with the tp_hash slot (added in 2.6b2) are now documented
1165
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001166- Issue #643841: The language reference now provides more detailed
1167 coverage of the lookup process for special methods. The disclaimers
1168 regarding lack of coverage of new-style classes have also been
1169 removed, since the coverage is now fairly reasonable.

1178-----------------
1179
Georg Brandl3e483f62008-07-16 22:57:41 +00001180- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1181 its methods now allow for items objects that can be converted to
1182 an integer using operator.index().
1183
Mark Dickinson64b7e502008-07-16 09:40:03 +00001184- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1185 produced a ValueError instead of giving the correct float.
1186
Eric Smitha5fa5a22008-07-16 00:11:49 +00001187- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1188 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1189
Mark Dickinson7103aa42008-07-15 19:08:33 +00001190- Issue #3008: the float type has a new instance method 'float.hex'
1191 and a new class method 'float.fromhex' to convert floating-point
1192 numbers to and from hexadecimal strings, respectively.
1193
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001194- Issue #2235: __hash__ is once again inherited by default. To allow
1195 collections.Hashable to remain meaningful in the presence of the
1196 default hash implementation (object.__hash__), it is now possible
1197 to explicit block inheritance of hash by setting __hash__=None at
1198 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1199 level.
1200
Nick Coghlanb028f502008-07-13 14:52:36 +00001201- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1202 the parent module cannot be found while performing an absolute import.
1203 This means that an incorrectly defined __package__ attribute will
1204 now only prevent relative imports in that module rather than causing
1205 all imports from that module to fail.
1206
Nick Coghlan14ff9942008-07-08 14:21:42 +00001207- Issue #2517: Allow unicode messages in Exceptions again by correctly
1208 bypassing the instance dictionary when looking up __unicode__ on
1209 new-style classes.
1210
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001211- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1212 set to a custom object whose write() method happens to install
1213 another file in sys.stdout.
1214
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001215- Issue #3088: Corrected a race condition in classes derived from
1216 threading.local: the first member set by a thread could be saved in
1217 another thread's dictionary.
1218
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001219- Issue #3004: Minor change to slice.indices(): the start and stop
1220 arguments are now treated identically, making the behaviour easier
1221 to describe and understand. For example, slice(None, -10,
1222 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1223 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1224 10, -1).
1225
Georg Brandl278fc502008-07-19 12:46:12 +00001226- Issue #3219: Calling a function with repeated keyword arguments,
1227 f(a=2, a=23), would not cause a syntax error. This was a regression
1228 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001229
Georg Brandl278fc502008-07-19 12:46:12 +00001230- Issue #2862: Make int and float freelist management consistent with
1231 other freelists. Changes their CompactFreeList apis into
1232 ClearFreeList apis and calls them via gc.collect().

1235-------
1236
Thomas Heller57adf222008-08-14 19:10:48 +00001237- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1238 api functions without holding the GIL, which could lead to a fatal
1239 error when they failed.
1240
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001241- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001249- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1250 ForkingPickler.register() to resolve conflict with ctypes.
1251
Vinay Sajip51e65192008-07-18 09:01:10 +00001252- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00001254- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1255 a valid dlerror() message.
1256
Thomas Heller2bad6572008-07-15 17:19:50 +00001257- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1258 incomplete structure was created.
1259
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001260- Issue #3339: dummy_thread.acquire() should not return None.
1261
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001262- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1263
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001264- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001265
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001266- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1267 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001268 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001269 content-length. The problem had been corrected in the 2.4 branch, but never
1270 merged into trunk.
1271

1677 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001678 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001679
1680 This is controlled by the configure argument ``--with-universal-archs``:
1681
1682 - ``--with-universal-archs=all``: install 4-way universal
1683
1684 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1685
1686 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1687
1688 This option should be used in combination with ``--enable-universalsdk=``.
1689
1690 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 +00001740- Issue #1631171: Re-implement the 'warnings' module in C (the
1741 original Python code has been kept as backup). This will allow for
1742 using the 'warning's machinery in such places as the parser where
1743 use of pure Python code is not possible. Both the ``showarning()``
1744 and ``formatwarning()`` gain an optional 'line' argument which is
1745 not called by default for backwards-compatibility reasons. Setting
1746 ``warnings.showwarning()`` to an implementation that lacks support
1747 for the ``line`` argument will raise a DeprecationWarning.

1771
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001772- The getpass module has been improved on Unix. It now uses /dev/tty
1773 by default and uses stderr instead of stdout. A GetPassWarning is
1774 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001789- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001790 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001810- Issue #2550: The approach used by client/server code for obtaining
1811 ports to listen on in network-oriented tests has been refined in an
1812 effort to facilitate running multiple instances of the entire
1813 regression test suite in parallel without issue.
1814 test_support.bind_port() has been fixed such that it will always
1815 return a unique port -- which wasn't always the case with the
1816 previous implementation, especially if socket options had been set
1817 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1818 new implementation of bind_port() will actually raise an exception
1819 if it is passed an AF_INET/SOCK_STREAM socket with either the
1820 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1821 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1822 the socket it's been passed. This currently only applies to
1823 Windows. This option prevents any other sockets from binding to the
1824 host/port we've bound to, thus removing the possibility of the
1825 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1826 when a second SOCK_STREAM socket binds and accepts to a host/port
1827 that's already been bound by another socket. The optional preferred
1828 port parameter to bind_port() has been removed. Under no
1829 circumstances should tests be hard coding ports!
1830
1831 test_support.find_unused_port() has also been introduced, which will
1832 pass a temporary socket object to bind_port() in order to obtain an
1833 unused port. The temporary socket object is then closed and
1834 deleted, and the port is returned. This method should only be used
1835 for obtaining an unused port in order to pass to an external program
1836 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1837 a parameter to a server-oriented class that doesn't give you direct
1838 access to the underlying socket used.
1839
1840 Finally, test_support.HOST has been introduced, which should be used
1841 for the host argument of any relevant socket calls (i.e. bind and
1842 connect).

2116Core and builtins
2117-----------------
2118
Fred Drakea8ee94b2008-03-01 02:45:07 +00002119- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002120 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002121
Georg Brandlad61bc82008-02-23 15:11:18 +00002122- Issue #2067: file.__exit__() now calls subclasses' close() method.
2123
2124- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002125
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002126- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002127 issue 215555 for a discussion.
2128
Eric Smitha73fbe72008-02-23 03:09:44 +00002129- Added the future_builtins module, which contains hex() and oct().
2130 These are the PEP 3127 version of these functions, designed to be
2131 compatible with the hex() and oct() builtins from Python 3.0. They
2132 differ slightly in their output formats from the existing, unchanged
2133 Python 2.6 builtins. The expected usage of the future_builtins
2134 module is:
2135 from future_builtins import hex, oct
2136
Eric Smith7ef40bf2008-02-20 23:34:22 +00002137- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2138 exponents for exponents with absolute value < 100. Follows C99
2139 standard. This is a change on Windows, which would use 3 digits.
2140 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2141 so that any alterations it does to the resulting string will be
2142 available in stringlib/formatter.h (for float.__format__).
2143
Eric Smith5a3c1352008-02-19 13:21:56 +00002144- Implemented PEP 3101, Advanced String Formatting. This adds a new
2145 builtin format(); a format() method for str and unicode; a
2146 __format__() method to object, str, unicode, int, long, float, and
2147 datetime; the class string.Formatter; and the C API
2148 PyObject_Format().
2149
Georg Brandl3ee81df2008-05-17 18:14:43 +00002150- Fixed several potential crashes, all caused by specially crafted
2151 __del__ methods exploiting objects in temporarily inconsistent
2152 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002153
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002154- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002155 prevent a possible crash: an Abstract Base Class would try to access
2156 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002157
Georg Brandl3ee81df2008-05-17 18:14:43 +00002158- Fixed repr() and str() of complex numbers with infinity or nan as
2159 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002160
Georg Brandl3ee81df2008-05-17 18:14:43 +00002161- Clear all free lists during a gc.collect() of the highest generation
2162 in order to allow pymalloc to free more arenas. Python may give back
2163 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002164
Georg Brandl3ee81df2008-05-17 18:14:43 +00002165- Issue #2045: Fix an infinite recursion triggered when printing a
2166 subclass of collections.defaultdict, if its default_factory is set
2167 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002168
Christian Heimesf75dbef2008-02-08 00:11:31 +00002169- Fixed a minor memory leak in dictobject.c. The content of the free
2170 list was not freed on interpreter shutdown.
2171
Georg Brandl3ee81df2008-05-17 18:14:43 +00002172- Limit free list of method and builtin function objects to 256
2173 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002174
Georg Brandl3ee81df2008-05-17 18:14:43 +00002175- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2176 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002177 to compact the internal free lists of pre-allocted ints and floats.
2178
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2180 calls. Python expected the return type int but the fork familie
2181 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002182
Georg Brandl3ee81df2008-05-17 18:14:43 +00002183- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2184 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002185
Georg Brandl3ee81df2008-05-17 18:14:43 +00002186- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2187 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002188
Georg Brandl3ee81df2008-05-17 18:14:43 +00002189- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2190 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002191
Georg Brandl3ee81df2008-05-17 18:14:43 +00002192- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2193 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002194
Georg Brandl3ee81df2008-05-17 18:14:43 +00002195- Patch #1473257: generator objects gain a gi_code attribute. This is
2196 the same object as the func_code attribute of the function that
2197 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002198
Georg Brandl3ee81df2008-05-17 18:14:43 +00002199- Issue #1920: "while 0" statements were completely removed by the
2200 compiler, even in the presence of an "else" clause, which is
2201 supposed to be run when the condition is false. Now the compiler
2202 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002203
Guido van Rossumeead05f2008-01-24 18:21:02 +00002204- A few crashers fixed: weakref_in_del.py (issue #1377858);
2205 loosing_dict_ref.py (issue #1303614, test67.py);
2206 borrowed_ref_[34].py (not in tracker).
2207
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002208- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002209 suppressed while an extension is loaded by calling SetErrorMode in
2210 dynload_win.c. The error is still reported properly.
2211
Georg Brandl3ee81df2008-05-17 18:14:43 +00002212- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002213 several extension methods and modules do not work without unicode
2214 support.
2215
Georg Brandl26543b12008-01-21 18:36:51 +00002216- Issue #1882: when compiling code from a string, encoding cookies in the
2217 second line of code were not always recognized correctly.
2218
Georg Brandl14404b62008-01-19 19:27:05 +00002219- Issue #1679: "0x" was taken as a valid integer literal.
2220
Georg Brandl6caad7d2008-01-26 14:19:22 +00002221- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002222 added.
2223
Christian Heimesc94e2b52008-01-14 04:13:37 +00002224- sys.float_info / PyFloat_GetInfo: The floating point information
2225 object was converted from a dict to a specialized structseq object.
2226
Georg Brandl3ee81df2008-05-17 18:14:43 +00002227- Patch #1816: Added sys.flags structseq. It exposes the status of
2228 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002229
Georg Brandl3ee81df2008-05-17 18:14:43 +00002230- Objects/structseq.c: Implemented new structseq representation. The
2231 patch makes structseqs (e.g. the return value of os.stat) more
2232 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002233
Georg Brandl3ee81df2008-05-17 18:14:43 +00002234- Patch #1700288: added a type attribute cache that caches method
2235 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002236
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002237- Bug #1776: __import__() no longer accepts filenames on any platform.
2238 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002239

2241
Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2243 envvar and sys.dont_write_bytecode attribute. All these can be set
2244 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002245
Georg Brandl3ee81df2008-05-17 18:14:43 +00002246- Improve some exception messages when Windows fails to load an
2247 extension module. Now we get for example '%1 is not a valid Win32
2248 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002249
Georg Brandl3ee81df2008-05-17 18:14:43 +00002250- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002252- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2253 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002254
Christian Heimes0a8143f2007-12-18 23:22:54 +00002255- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002256 and INF. float("nan"), float("inf") and float("-inf") now work on
2257 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002258
Georg Brandl3ee81df2008-05-17 18:14:43 +00002259- Compiler now generates simpler and faster code for dictionary
2260 literals. The oparg for BUILD_MAP now indicates an estimated
2261 dictionary size. There is a new opcode, STORE_MAP, for adding
2262 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002263
Georg Brandl3ee81df2008-05-17 18:14:43 +00002264- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002272- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002273 SystemError.
2274
Nick Coghlanef01d822007-12-03 12:55:17 +00002275- PEP 366: Allow explicit relative imports when executing modules
2276 inside packages with the -m switch via a new module level
2277 __package__ attribute.
2278

2280 running, and if the deallocation of its frames somehow calls the
2281 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002282

2292 file can now be directly executed by passing their name to the
2293 interpreter. The directory/zipfile is automatically inserted as the
2294 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002295
Georg Brandl3ee81df2008-05-17 18:14:43 +00002296- Issue #1265: Fix a problem with sys.settrace, if the tracing
2297 function uses a generator expression when at the same time the
2298 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002299
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002300- sets and frozensets now have an isdisjoint() method.
2301
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002302- optimize the performance of builtin.sum().
2303
Neal Norwitz44f326e2007-10-05 05:29:17 +00002304- Fix warnings found by the new version of the Coverity checker.
2305
Georg Brandl3ee81df2008-05-17 18:14:43 +00002306- The enumerate() builtin function is no longer bounded to sequences
2307 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2308 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002309
Georg Brandl3ee81df2008-05-17 18:14:43 +00002310- Issue #1686386: Tuple's tp_repr did not take into account the
2311 possibility of having a self-referential tuple, which is possible
2312 from C code. Nor did object's tp_str consider that a type's tp_str
2313 could do something that could lead to an inifinite recursion.
2314 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2315 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002316
Georg Brandl3ee81df2008-05-17 18:14:43 +00002317- Issue #1164: It was possible to trigger deadlock when using the
2318 'print' statement to write to a file since the GIL was not released
2319 as needed. Now PyObject_Print() does the right thing along with
2320 various tp_print implementations of the built-in types and those in
2321 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002322
Georg Brandl3ee81df2008-05-17 18:14:43 +00002323- Issue #1147: Exceptions were directly allowing string exceptions in
2324 their throw() method even though string exceptions no longer
2325 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002326
Georg Brandl3ee81df2008-05-17 18:14:43 +00002327- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002330- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002331 PyObject_Call() never calling back out to Python code to trigger
2332 recursion depth updates/checks. Required the creation of a static
2333 RuntimeError instance in case normalizing an exception put the

Neal Norwitz0ac60192007-05-27 04:08:54 +00002350- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002351 __*__ attributes. (Some already existed, e.g., __doc__ and
2352 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002353
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002354- Add -3 option to the interpreter to warn about features that are

2359
Collin Winter62903052007-05-18 23:11:24 +00002360- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002361 "except E as target:". This is to provide forwards compatibility
2362 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002363
Brett Cannon229cee22007-05-05 01:34:02 +00002364- Deprecate BaseException.message as per PEP 352.
2365
Georg Brandl3ee81df2008-05-17 18:14:43 +00002366- Issue #1303614: don't expose object's __dict__ when the dict is

2368
Vinay Sajip8549ce32007-05-06 17:53:37 +00002369- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002370 setting a plain string, ie don't expand to single letter identifiers.
2371
Raymond Hettinger13936692007-04-11 18:40:58 +00002372- Request #1191699: Slices can now be pickled.
2373
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002374- Request #1193128: str.translate() now allows a None argument for

2382
Guido van Rossum143b5642007-03-23 04:58:42 +00002383- Bug #1683368: The object.__init__() and object.__new__() methods are
2384 now stricter in rejecting excess arguments. The only time when
2385 either allows excess arguments is when it is not overridden and the
2386 other one is. For backwards compatibility, when both are
2387 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002388 warning later). Also, type.__init__() insists on the same signature
2389 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002390
Georg Brandl3ee81df2008-05-17 18:14:43 +00002391- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2392 object to complex using its __complex__() method before falling back
2393 to the __float__() method. Therefore, the functions in the cmath
2394 module now can operate on objects that define a __complex__()
2395 method.

2412
Georg Brandl7b9c5552007-03-12 14:30:05 +00002413- Bug #1678647: write a newline after printing an exception in any
2414 case, even when converting the value to a string failed.
2415
Georg Brandl871f1bc2007-03-12 13:17:36 +00002416- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002417 its argument, if it exists. If not, it will work like before. This
2418 allows customizing the output of dir() in the presence of a
2419 __getattr__().

2429 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002430
Georg Brandlaa2321b2007-03-07 00:40:28 +00002431- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002432 makes the filenames the warning module prints much more sensible
2433 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002434

Georg Brandl0fca97a2007-03-05 22:28:08 +00002446- Patch #1674228: when assigning a slice (old-style), check for the
2447 sq_ass_slice instead of the sq_slice slot.
2448
Georg Brandl3ee81df2008-05-17 18:14:43 +00002449- When printing an unraisable error, don't print exceptions. before

3074
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- unittest now verifies more of its assumptions. In particular,

3077 accepted in TestSuite.addTest(). This should cause no
3078 incompatibility since it never made sense with ordinary subclasses
3079 -- the failure just occurred later, with a more cumbersome
3080 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003361- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3362 with RFC 3207 and forgets any knowledge obtained from the server not
3363 obtained from the TLS negotiation itself. Patch contributed by Bill
3364 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003365
Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003367 that the SMTP.starttls() caller no longer needs to call ehlo()
3368 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003369 does not claim to support starttls. Adds the
3370 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3451 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3452 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003469 time so that opening a database previously created with the DB_DUP
3470 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3471 opens. Specifically: dictionary assignment to a DB object will
3472 replace all values for a given key when the database allows
3473 duplicate values. DB users should use DB.put(k, v) when they want
3474 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003475

3481 characters with ASCII value less than 32. Also, it correctly quotes
3482 dots only if they occur on a single line, as opposed to the previous
3483 behavior of quoting dots if they are the second character of any
3484 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003485

Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- Makefile.pre.in(buildbottest): Run an optional script
3802 pybuildbot.identify to include some information about the build
3803 environment.

3807-----
3808
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809- Unified naming convention for free lists and their limits. All free
3810 lists in Object/ are named ``free_list``, the counter ``numfree``
3811 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3812 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003813
Georg Brandl3ee81df2008-05-17 18:14:43 +00003814- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3815 to ``PyTuple_SetItem``, it can be used to populate a brand new
3816 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003817
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003818- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003819
Georg Brandl3ee81df2008-05-17 18:14:43 +00003820- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3821 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3822 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003823
3824- Patch #1720595: add T_BOOL to the range of structmember types.
3825
3826- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3827 ``PyFloat_GetInfo()`` to the float API.
3828
Georg Brandl3ee81df2008-05-17 18:14:43 +00003829- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3830 of w# format code incorrectly truncated the length to an int, even
3831 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3832 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003833
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3835 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- PEP 3123: Provide forward compatibility with Python 3.0, while
3838 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3839 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003840
Georg Brandl3ee81df2008-05-17 18:14:43 +00003841- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3842 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003843
3844- Patch #1733960: Allow T_LONGLONG to accept ints.
3845
3846- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3847
Christian Heimes000a0742008-01-03 22:16:32 +00003848- Added a new API function ``PyImport_ImportModuleNoBlock``.
3849
Georg Brandl6caad7d2008-01-26 14:19:22 +00003850- Bug #1637022: Prefix AST symbols with _Py_.
3851
3852- Fix some leftovers from the conversion from int to Py_ssize_t
3853 (relevant to strings and sequences of more than 2**31 items).
3854
3855- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3856 outside of pystate.c and should not be necessary.
3857
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3859 absolute imports. In earlier versions they might have used relative
3860 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3863 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003864
Georg Brandl3ee81df2008-05-17 18:14:43 +00003865- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3866 macro so it can be used as an expression.

3871
Georg Brandl3ee81df2008-05-17 18:14:43 +00003872- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3873 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3874 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3875 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003876
Georg Brandl3ee81df2008-05-17 18:14:43 +00003877- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
3878 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003890- Removed the macfs module. It had been deprecated since Python 2.5.
3891 This lead to the deprecation of macostools.touched() as it relied
3892 solely on macfs and was a no-op under OS X.
