322 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
323 partial bzip2 compressed data.
324
Benjamin Peterson373498f2009-03-22 17:49:21 +0000325- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

376 check it is possible to segfault the interpreter.

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

451- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
452 302 conformant loader) will now work correctly in most cases (they
453 are still subject to the constraints that exist for all code running
454 from inside a module loaded via a PEP 302 loader and attempting to

616What's New in Python 2.6.1
617==========================
618
619*Release date: 04-Dec-2008*
620
621Core and Builtins
622-----------------
623
624- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
625 interpreter to abort ("Fatal Python error: Could not reset the stack!")
626 instead of throwing a MemoryError.
627
628- Issue #4367: Python would segfault during compiling when the unicodedata
629 module couldn't be imported and \N escapes were present.
630
631- Issue #4348: Some bytearray methods returned that didn't cause any change to
632 the bytearray, returned the same bytearray instead of a copy.
633
634- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
635
636- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
637
638- Issue #4048: The parser module now correctly validates relative imports.
639
640- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
641 exec statement.
642
643- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
644 method does not return iterators for the 4th and 5th items.
645
646- Issue #4209: Enabling unicode_literals and the print_function in the same
647 __future__ import didn't work.
648
649- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
650 returned a path longer than MAX_PATH. (But It's doubtful this code path is
651 really executed because I cannot move to such directory on win2k)
652
653- Issue #4069: When set.remove(element) is used with a set element, the element
654 is temporarily replaced with an equivalent frozenset. But the eventual
655 KeyError would always report the empty frozenset([]) as the missing key. Now
656 it correctly refers to the initial element.
657
658- Fixed C99 style comments in several files. Python is now C89 compatible
659 again.
660
661Library
662-------
663
Christian Heimes268be912008-11-28 11:03:48 +0000664- Issue #3741: DISTUTILS_USE_SDK set causes msvc9compiler.py to raise an
665 exception.
666

807
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000808- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
809 PyString_FromFormat or PyErr_Format to display size_t values. The macro
810 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
811 ``printf`` function, whereas PyString_FromFormat has an independent
812 implementation and uses "%zd" on all platforms for size_t values.
813 This makes a difference on win64, where ``printf`` needs "%Id" to display
814 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000834 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
835 mechanism. In the process, fix a bug where isinstance() and issubclass(),

837 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
838 type object.

Guido van Rossumf8402962008-08-20 15:01:50 +0000982- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
983 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
984 extensions do not automatically benefit from the class attribute
985 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
986 to their tp_flags field if they care. This is a backwards
987 compatibility feature; in 3.0, all types will use the cache by
988 default.
989
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000990- Keyword arguments can now follow starred arguments. (``f(a, *args,
991 keyword=23)`` is now valid syntax.)
992
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000993- ctypes function pointers that are COM methods have a boolean True
994 value again.
995
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000996- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
997 by denying s# to parse objects that have a releasebuffer procedure,
998 and introducing s*.
999
Georg Brandl1e13ea92008-08-11 09:07:59 +00001000- Issue #3537: Fix an assertion failure when an empty but presized dict
1001 object was stored in the freelist.
1002
Mark Dickinsonb6467572008-08-04 21:30:09 +00001003- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1004 ValueError consistently across platforms.
1005
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001006- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1007 (64bit Unix, for example), unichr() would truncate its argument and return
1008 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1009
Neal Norwitze7d8be82008-07-31 17:17:14 +00001010- Apply security patches from Apple.
1011
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001012- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1013 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1014
Antoine Pitrou92f82162008-07-25 22:22:08 +00001015- Issue #1819: function calls with several named parameters are now on
1016 average 35% faster (as measured by pybench).
1017
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001018- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1019 the python debugger steps into a class statement: the free variables (local
1020 variables defined in an outer scope) would be deleted from the outer scope.
1021
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001022- Issue #2620: Overflow checking when allocating or reallocating memory
1023 was not always being done properly in some python types and extension
1024 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1025 all been updated to perform better checks and places in the code that
1026 would previously leak memory on the error path when such an allocation
1027 failed have been fixed.

1031
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001032- Issue #3612: Added some missing basic types in ctypes.wintypes.
1033
Benjamin Petersone977ad42008-08-20 01:42:01 +00001034- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1035 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1036
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001037- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1038 version reported by these tools does not necessarily follow the python
1039 version numbering scheme, so the module is less strict when parsing it.
1040
Nick Coghlanf70385a2008-08-18 12:42:46 +00001041- Issue #2235: Added Py3k warnings for types which will become unhashable
1042 under the stricter __hash__ inheritance rules in 3.0. Several types
1043 which did not meet the rules for hash invariants and were already
1044 unhashable in 3.0 have now been explicitly flagged as unhashable in
1045 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1046 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1047
Brett Cannon88f801d2008-08-18 00:46:22 +00001048- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1049 imported into the module but exposed as part of the module's API.
1050
Brett Cannon7b96f072008-08-18 00:41:11 +00001051- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1052
Brett Cannon46225e72008-08-18 00:36:52 +00001053- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1056
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001057- Issue #3575: Incremental decoder's decode function now takes bytearray
1058 by using 's*' instead of 't#'.
1059
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001060- Issue #2222: Fixed reference leak when occured os.rename()
1061 fails unicode conversion on 2nd parameter. (windows only)
1062
Facundo Batista94f243a2008-08-17 03:38:39 +00001063- Issue 2464. urllib2 now supports a malformation in the URL received
1064 in a redirect.
1065
Brett Cannonabe423e2008-08-16 21:47:07 +00001066- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001067 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001068
Facundo Batistaeb90b782008-08-16 14:44:07 +00001069- Issue #2776: fixed small issue when handling an URL with double slash
1070 after a 302 response in the case of not going through a proxy.
1071
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001072- Issue #2676: in the email package, content-type parsing was hanging on
1073 pathological input because of quadratic or exponential behaviour of a
1074 regular expression.
1075
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001076- Issue #3476: binary buffered reading through the new "io" library is now
1077 thread-safe.
1078
Brett Cannonbf3157b2008-08-14 05:00:03 +00001079- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1080 since mimetools itself is deprecated. Because modules are cached, all
1081 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1082
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001083- Issue #3134: shutil referenced undefined WindowsError symbol.
1084
Robert Schuppenies14646332008-08-10 11:01:53 +00001085- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1086 menu entries were not deleted.
1087
Brett Cannon83e81842008-08-09 23:30:55 +00001088- Copied the implementation of reduce() to _functools.reduce() to have a
1089 version that did not raise a DeprecationWarning under -3.
1090
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001091- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1092 a MemoryError rather than silently stop the iteration.
1093
Guido van Rossum59ce9012008-08-09 14:55:34 +00001094- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1095 to _sre.compile() will now be rejected. This should not affect anybody
1096 since the re.compile() function never generates invalid re-bytecode.
1097
Skip Montanaroa032bf42008-08-08 22:52:51 +00001098- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1099 upon first access it can be automatically initialized from the csv file if
1100 it wasn't initialized during instantiation.
1101
Brett Cannon3aa2a492008-08-06 22:28:09 +00001102- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1103 the reload() built-in has been removed.
1104
Brett Cannon7e30b672008-08-04 21:52:25 +00001105- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001106 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001107 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1108 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1109 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1110 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,

1114 raised an AttributeError.
1115
Benjamin Peterson01a24322008-07-28 23:35:27 +00001116- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001117 asking for a specific length. This problem only affected files opened
1118 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001119
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001120- Issue #3449: Update decimal module to use most recent specification
1121 (v. 1.68) and tests (v. 2.58) from IBM.
1122
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001123- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1131
1132- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1133 invalid arguments.
1134
1135- Issue #3302: Fix several crashes when calling locale's gettext functions
1136 with None arguments.
1137
1138- Issue #3389: Allow resolving dotted names for handlers in logging
1139 configuration files.
1140
1141- Deprecate the sunaudio module for removal in Python 3.0.
1142
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001143- Issue #3394: zipfile.writestr sets external attributes when passed a
1144 file name rather than a ZipInfo instance, so files are extracted with
1145 mode 0600 rather than 000 under Unix.
1146
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001147- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1148 argument in python 2.5, this broke code that subclassed Popen to include its
1149 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001159- Issue #2235: the C API function PyObject_HashNotImplemented and its
1160 interaction with the tp_hash slot (added in 2.6b2) are now documented
1161
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001162- Issue #643841: The language reference now provides more detailed
1163 coverage of the lookup process for special methods. The disclaimers
1164 regarding lack of coverage of new-style classes have also been
1165 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001173Core and Builtins
1174-----------------
1175
Georg Brandl3e483f62008-07-16 22:57:41 +00001176- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1177 its methods now allow for items objects that can be converted to
1178 an integer using operator.index().
1179
Mark Dickinson64b7e502008-07-16 09:40:03 +00001180- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1181 produced a ValueError instead of giving the correct float.
1182
Eric Smitha5fa5a22008-07-16 00:11:49 +00001183- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1184 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1185
Mark Dickinson7103aa42008-07-15 19:08:33 +00001186- Issue #3008: the float type has a new instance method 'float.hex'
1187 and a new class method 'float.fromhex' to convert floating-point
1188 numbers to and from hexadecimal strings, respectively.
1189
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001190- Issue #2235: __hash__ is once again inherited by default. To allow
1191 collections.Hashable to remain meaningful in the presence of the
1192 default hash implementation (object.__hash__), it is now possible
1193 to explicit block inheritance of hash by setting __hash__=None at
1194 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1195 level.
1196
Nick Coghlanb028f502008-07-13 14:52:36 +00001197- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1198 the parent module cannot be found while performing an absolute import.
1199 This means that an incorrectly defined __package__ attribute will
1200 now only prevent relative imports in that module rather than causing
1201 all imports from that module to fail.
1202
Nick Coghlan14ff9942008-07-08 14:21:42 +00001203- Issue #2517: Allow unicode messages in Exceptions again by correctly
1204 bypassing the instance dictionary when looking up __unicode__ on
1205 new-style classes.
1206
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001207- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1208 set to a custom object whose write() method happens to install
1209 another file in sys.stdout.
1210
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001211- Issue #3088: Corrected a race condition in classes derived from
1212 threading.local: the first member set by a thread could be saved in
1213 another thread's dictionary.
1214
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001215- Issue #3004: Minor change to slice.indices(): the start and stop
1216 arguments are now treated identically, making the behaviour easier
1217 to describe and understand. For example, slice(None, -10,
1218 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1219 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1220 10, -1).
1221
Georg Brandl278fc502008-07-19 12:46:12 +00001222- Issue #3219: Calling a function with repeated keyword arguments,
1223 f(a=2, a=23), would not cause a syntax error. This was a regression
1224 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001225
Georg Brandl278fc502008-07-19 12:46:12 +00001226- Issue #2862: Make int and float freelist management consistent with
1227 other freelists. Changes their CompactFreeList apis into
1228 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001229

1231-------
1232
Thomas Heller57adf222008-08-14 19:10:48 +00001233- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1234 api functions without holding the GIL, which could lead to a fatal
1235 error when they failed.
1236
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001237- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001245- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1246 ForkingPickler.register() to resolve conflict with ctypes.
1247
Vinay Sajip51e65192008-07-18 09:01:10 +00001248- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001249
Thomas Heller880f5292008-07-15 19:39:38 +00001250- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1251 a valid dlerror() message.
1252
Thomas Heller2bad6572008-07-15 17:19:50 +00001253- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1254 incomplete structure was created.
1255
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001256- Issue #3339: dummy_thread.acquire() should not return None.
1257
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001258- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1259
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001260- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001261
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001262- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1263 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001264 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001265 content-length. The problem had been corrected in the 2.4 branch, but never
1266 merged into trunk.
1267
Georg Brandle78fbcc2008-07-05 10:13:36 +00001268- Issue #2663: add filtering capability to shutil.copytree().

1271
1272- Issue #1526: Allow more than 64k files to be added to Zip64 file.
1273

1671
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001672- On MacOS X it is now possible to install the framework in 64-bit
1673 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001674 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001675
1676 This is controlled by the configure argument ``--with-universal-archs``:
1677
1678 - ``--with-universal-archs=all``: install 4-way universal
1679
1680 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1681
1682 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1683
1684 This option should be used in combination with ``--enable-universalsdk=``.
1685
1686 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 +00001736- Issue #1631171: Re-implement the 'warnings' module in C (the
1737 original Python code has been kept as backup). This will allow for
1738 using the 'warning's machinery in such places as the parser where
1739 use of pure Python code is not possible. Both the ``showarning()``
1740 and ``formatwarning()`` gain an optional 'line' argument which is
1741 not called by default for backwards-compatibility reasons. Setting
1742 ``warnings.showwarning()`` to an implementation that lacks support
1743 for the ``line`` argument will raise a DeprecationWarning.

1767
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001768- The getpass module has been improved on Unix. It now uses /dev/tty
1769 by default and uses stderr instead of stdout. A GetPassWarning is
1770 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00001771

Georg Brandl3ee81df2008-05-17 18:14:43 +00001785- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001786 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001806- Issue #2550: The approach used by client/server code for obtaining
1807 ports to listen on in network-oriented tests has been refined in an
1808 effort to facilitate running multiple instances of the entire
1809 regression test suite in parallel without issue.
1810 test_support.bind_port() has been fixed such that it will always
1811 return a unique port -- which wasn't always the case with the
1812 previous implementation, especially if socket options had been set
1813 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1814 new implementation of bind_port() will actually raise an exception
1815 if it is passed an AF_INET/SOCK_STREAM socket with either the
1816 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1817 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1818 the socket it's been passed. This currently only applies to
1819 Windows. This option prevents any other sockets from binding to the
1820 host/port we've bound to, thus removing the possibility of the
1821 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1822 when a second SOCK_STREAM socket binds and accepts to a host/port
1823 that's already been bound by another socket. The optional preferred
1824 port parameter to bind_port() has been removed. Under no
1825 circumstances should tests be hard coding ports!
1826
1827 test_support.find_unused_port() has also been introduced, which will
1828 pass a temporary socket object to bind_port() in order to obtain an
1829 unused port. The temporary socket object is then closed and
1830 deleted, and the port is returned. This method should only be used
1831 for obtaining an unused port in order to pass to an external program
1832 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1833 a parameter to a server-oriented class that doesn't give you direct
1834 access to the underlying socket used.
1835
1836 Finally, test_support.HOST has been introduced, which should be used

2112Core and builtins
2113-----------------
2114
Fred Drakea8ee94b2008-03-01 02:45:07 +00002115- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002116 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002117
Georg Brandlad61bc82008-02-23 15:11:18 +00002118- Issue #2067: file.__exit__() now calls subclasses' close() method.
2119
2120- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002121
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002122- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002123 issue 215555 for a discussion.
2124
Eric Smitha73fbe72008-02-23 03:09:44 +00002125- Added the future_builtins module, which contains hex() and oct().
2126 These are the PEP 3127 version of these functions, designed to be
2127 compatible with the hex() and oct() builtins from Python 3.0. They
2128 differ slightly in their output formats from the existing, unchanged
2129 Python 2.6 builtins. The expected usage of the future_builtins
2130 module is:
2131 from future_builtins import hex, oct
2132
Eric Smith7ef40bf2008-02-20 23:34:22 +00002133- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2134 exponents for exponents with absolute value < 100. Follows C99
2135 standard. This is a change on Windows, which would use 3 digits.
2136 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2137 so that any alterations it does to the resulting string will be
2138 available in stringlib/formatter.h (for float.__format__).
2139
Eric Smith5a3c1352008-02-19 13:21:56 +00002140- Implemented PEP 3101, Advanced String Formatting. This adds a new
2141 builtin format(); a format() method for str and unicode; a
2142 __format__() method to object, str, unicode, int, long, float, and
2143 datetime; the class string.Formatter; and the C API
2144 PyObject_Format().
2145
Georg Brandl3ee81df2008-05-17 18:14:43 +00002146- Fixed several potential crashes, all caused by specially crafted
2147 __del__ methods exploiting objects in temporarily inconsistent
2148 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002149
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002150- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002151 prevent a possible crash: an Abstract Base Class would try to access
2152 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002153
Georg Brandl3ee81df2008-05-17 18:14:43 +00002154- Fixed repr() and str() of complex numbers with infinity or nan as
2155 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002156
Georg Brandl3ee81df2008-05-17 18:14:43 +00002157- Clear all free lists during a gc.collect() of the highest generation
2158 in order to allow pymalloc to free more arenas. Python may give back
2159 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002160
Georg Brandl3ee81df2008-05-17 18:14:43 +00002161- Issue #2045: Fix an infinite recursion triggered when printing a
2162 subclass of collections.defaultdict, if its default_factory is set
2163 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002164
Christian Heimesf75dbef2008-02-08 00:11:31 +00002165- Fixed a minor memory leak in dictobject.c. The content of the free
2166 list was not freed on interpreter shutdown.
2167
Georg Brandl3ee81df2008-05-17 18:14:43 +00002168- Limit free list of method and builtin function objects to 256
2169 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002170
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2172 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002173 to compact the internal free lists of pre-allocted ints and floats.
2174
Georg Brandl3ee81df2008-05-17 18:14:43 +00002175- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2176 calls. Python expected the return type int but the fork familie
2177 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002178
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2180 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2183 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002184
Georg Brandl3ee81df2008-05-17 18:14:43 +00002185- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2186 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002187
Georg Brandl3ee81df2008-05-17 18:14:43 +00002188- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2189 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002190
Georg Brandl3ee81df2008-05-17 18:14:43 +00002191- Patch #1473257: generator objects gain a gi_code attribute. This is
2192 the same object as the func_code attribute of the function that
2193 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002194
Georg Brandl3ee81df2008-05-17 18:14:43 +00002195- Issue #1920: "while 0" statements were completely removed by the
2196 compiler, even in the presence of an "else" clause, which is
2197 supposed to be run when the condition is false. Now the compiler
2198 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002199
Guido van Rossumeead05f2008-01-24 18:21:02 +00002200- A few crashers fixed: weakref_in_del.py (issue #1377858);
2201 loosing_dict_ref.py (issue #1303614, test67.py);
2202 borrowed_ref_[34].py (not in tracker).
2203
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002204- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002205 suppressed while an extension is loaded by calling SetErrorMode in
2206 dynload_win.c. The error is still reported properly.
2207
Georg Brandl3ee81df2008-05-17 18:14:43 +00002208- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002209 several extension methods and modules do not work without unicode
2210 support.
2211
Georg Brandl26543b12008-01-21 18:36:51 +00002212- Issue #1882: when compiling code from a string, encoding cookies in the
2213 second line of code were not always recognized correctly.
2214
Georg Brandl14404b62008-01-19 19:27:05 +00002215- Issue #1679: "0x" was taken as a valid integer literal.
2216
Georg Brandl6caad7d2008-01-26 14:19:22 +00002217- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002218 added.
2219
Christian Heimesc94e2b52008-01-14 04:13:37 +00002220- sys.float_info / PyFloat_GetInfo: The floating point information
2221 object was converted from a dict to a specialized structseq object.
2222
Georg Brandl3ee81df2008-05-17 18:14:43 +00002223- Patch #1816: Added sys.flags structseq. It exposes the status of
2224 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002225
Georg Brandl3ee81df2008-05-17 18:14:43 +00002226- Objects/structseq.c: Implemented new structseq representation. The
2227 patch makes structseqs (e.g. the return value of os.stat) more
2228 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002229
Georg Brandl3ee81df2008-05-17 18:14:43 +00002230- Patch #1700288: added a type attribute cache that caches method
2231 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002232
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002233- Bug #1776: __import__() no longer accepts filenames on any platform.
2234 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002235
Georg Brandlaed6c662008-01-07 17:25:53 +00002236- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2237
Georg Brandl3ee81df2008-05-17 18:14:43 +00002238- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2239 envvar and sys.dont_write_bytecode attribute. All these can be set
2240 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002241
Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- Improve some exception messages when Windows fails to load an
2243 extension module. Now we get for example '%1 is not a valid Win32
2244 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002245
Georg Brandl3ee81df2008-05-17 18:14:43 +00002246- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002248- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2249 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002250
Christian Heimes0a8143f2007-12-18 23:22:54 +00002251- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002252 and INF. float("nan"), float("inf") and float("-inf") now work on
2253 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002254
Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Compiler now generates simpler and faster code for dictionary
2256 literals. The oparg for BUILD_MAP now indicates an estimated
2257 dictionary size. There is a new opcode, STORE_MAP, for adding
2258 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002259
Georg Brandl3ee81df2008-05-17 18:14:43 +00002260- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002262- Issue #1620: New property decorator syntax was modifying the
2263 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002264
Georg Brandl3ee81df2008-05-17 18:14:43 +00002265- Issue #1538: Avoid copying string in split/rsplit if the split char
2266 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002267
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002268- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002269 SystemError.
2270
Nick Coghlanef01d822007-12-03 12:55:17 +00002271- PEP 366: Allow explicit relative imports when executing modules
2272 inside packages with the -m switch via a new module level
2273 __package__ attribute.
2274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Issue #1402: Fix a crash on exit, when another thread is still
2276 running, and if the deallocation of its frames somehow calls the
2277 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002278

2288 file can now be directly executed by passing their name to the
2289 interpreter. The directory/zipfile is automatically inserted as the
2290 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002291
Georg Brandl3ee81df2008-05-17 18:14:43 +00002292- Issue #1265: Fix a problem with sys.settrace, if the tracing
2293 function uses a generator expression when at the same time the
2294 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002295
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002296- sets and frozensets now have an isdisjoint() method.
2297
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002298- optimize the performance of builtin.sum().
2299
Neal Norwitz44f326e2007-10-05 05:29:17 +00002300- Fix warnings found by the new version of the Coverity checker.
2301
Georg Brandl3ee81df2008-05-17 18:14:43 +00002302- The enumerate() builtin function is no longer bounded to sequences
2303 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2304 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002305
Georg Brandl3ee81df2008-05-17 18:14:43 +00002306- Issue #1686386: Tuple's tp_repr did not take into account the
2307 possibility of having a self-referential tuple, which is possible
2308 from C code. Nor did object's tp_str consider that a type's tp_str
2309 could do something that could lead to an inifinite recursion.
2310 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2311 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002312
Georg Brandl3ee81df2008-05-17 18:14:43 +00002313- Issue #1164: It was possible to trigger deadlock when using the
2314 'print' statement to write to a file since the GIL was not released
2315 as needed. Now PyObject_Print() does the right thing along with
2316 various tp_print implementations of the built-in types and those in
2317 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002318
Georg Brandl3ee81df2008-05-17 18:14:43 +00002319- Issue #1147: Exceptions were directly allowing string exceptions in
2320 their throw() method even though string exceptions no longer
2321 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002322
Georg Brandl3ee81df2008-05-17 18:14:43 +00002323- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002326- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002327 PyObject_Call() never calling back out to Python code to trigger
2328 recursion depth updates/checks. Required the creation of a static
2329 RuntimeError instance in case normalizing an exception put the
2330 recursion check value past its limit. Fixes crashers
2331 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002346- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002347 __*__ attributes. (Some already existed, e.g., __doc__ and
2348 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002349
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002350- Add -3 option to the interpreter to warn about features that are

2355
Collin Winter62903052007-05-18 23:11:24 +00002356- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002357 "except E as target:". This is to provide forwards compatibility
2358 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002359
Brett Cannon229cee22007-05-05 01:34:02 +00002360- Deprecate BaseException.message as per PEP 352.
2361
Georg Brandl3ee81df2008-05-17 18:14:43 +00002362- Issue #1303614: don't expose object's __dict__ when the dict is

2364
Vinay Sajip8549ce32007-05-06 17:53:37 +00002365- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002366 setting a plain string, ie don't expand to single letter identifiers.
2367
Raymond Hettinger13936692007-04-11 18:40:58 +00002368- Request #1191699: Slices can now be pickled.
2369
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002370- Request #1193128: str.translate() now allows a None argument for

2372 remaining characters.
2373
Georg Brandl5cb76c12007-03-21 09:00:39 +00002374- Patch #1682205: a TypeError while unpacking an iterable is no longer

2378
Guido van Rossum143b5642007-03-23 04:58:42 +00002379- Bug #1683368: The object.__init__() and object.__new__() methods are
2380 now stricter in rejecting excess arguments. The only time when
2381 either allows excess arguments is when it is not overridden and the
2382 other one is. For backwards compatibility, when both are
2383 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002384 warning later). Also, type.__init__() insists on the same signature
2385 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002386
Georg Brandl3ee81df2008-05-17 18:14:43 +00002387- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2388 object to complex using its __complex__() method before falling back
2389 to the __float__() method. Therefore, the functions in the cmath
2390 module now can operate on objects that define a __complex__()
2391 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002392

2394 __slots__. The old and the new class are still required to have the
2395 same slot names.

2408
Georg Brandl7b9c5552007-03-12 14:30:05 +00002409- Bug #1678647: write a newline after printing an exception in any
2410 case, even when converting the value to a string failed.
2411
Georg Brandl871f1bc2007-03-12 13:17:36 +00002412- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002413 its argument, if it exists. If not, it will work like before. This
2414 allows customizing the output of dir() in the presence of a
2415 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002416
Collin Winter276887b2007-03-12 16:11:39 +00002417- Patch #922167: Python no longer segfaults when faced with infinitely
2418 self-recursive reload() calls (as reported by bug #742342).
2419

2424 parthensized forms. This means complex(repr(x)) now works instead of
2425 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002426
Georg Brandlaa2321b2007-03-07 00:40:28 +00002427- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002428 makes the filenames the warning module prints much more sensible
2429 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002430
Georg Brandl49aafc92007-03-07 00:34:46 +00002431- Variant of patch #697613: don't exit the interpreter on a SystemExit
2432 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002433 variable is given, but break into the interactive interpreter just

Georg Brandl098cd692007-03-06 12:17:50 +00002441
Georg Brandl0fca97a2007-03-05 22:28:08 +00002442- Patch #1674228: when assigning a slice (old-style), check for the
2443 sq_ass_slice instead of the sq_slice slot.
2444
Georg Brandl3ee81df2008-05-17 18:14:43 +00002445- When printing an unraisable error, don't print exceptions. before
2446 the name. This duplicates the behavior whening normally printing
2447 exceptions.

2456 created a weakref on itself during a __del__ call for new-style
2457 classes (classic classes still have the bug).

3070
Georg Brandl3ee81df2008-05-17 18:14:43 +00003071- unittest now verifies more of its assumptions. In particular,

3073 accepted in TestSuite.addTest(). This should cause no
3074 incompatibility since it never made sense with ordinary subclasses
3075 -- the failure just occurred later, with a more cumbersome
3076 exception.

3355 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003356
Georg Brandl3ee81df2008-05-17 18:14:43 +00003357- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3358 with RFC 3207 and forgets any knowledge obtained from the server not
3359 obtained from the TLS negotiation itself. Patch contributed by Bill
3360 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003361
Georg Brandl3ee81df2008-05-17 18:14:43 +00003362- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003363 that the SMTP.starttls() caller no longer needs to call ehlo()
3364 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365 does not claim to support starttls. Adds the
3366 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3447 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3448 silently miscode subclasses of those types. Now, it raises a
3449 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003450

Georg Brandl3ee81df2008-05-17 18:14:43 +00003465 time so that opening a database previously created with the DB_DUP
3466 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3467 opens. Specifically: dictionary assignment to a DB object will
3468 replace all values for a given key when the database allows
3469 duplicate values. DB users should use DB.put(k, v) when they want
3470 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003471

3477 characters with ASCII value less than 32. Also, it correctly quotes
3478 dots only if they occur on a single line, as opposed to the previous
3479 behavior of quoting dots if they are the second character of any
3480 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003481

Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- Unified naming convention for free lists and their limits. All free
3806 lists in Object/ are named ``free_list``, the counter ``numfree``
3807 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3808 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003809
Georg Brandl3ee81df2008-05-17 18:14:43 +00003810- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3811 to ``PyTuple_SetItem``, it can be used to populate a brand new
3812 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003813
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003814- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003815
Georg Brandl3ee81df2008-05-17 18:14:43 +00003816- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3817 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3818 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003819
3820- Patch #1720595: add T_BOOL to the range of structmember types.
3821
3822- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3823 ``PyFloat_GetInfo()`` to the float API.
3824
Georg Brandl3ee81df2008-05-17 18:14:43 +00003825- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3826 of w# format code incorrectly truncated the length to an int, even
3827 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3828 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003829
Georg Brandl3ee81df2008-05-17 18:14:43 +00003830- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3831 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003832
Georg Brandl3ee81df2008-05-17 18:14:43 +00003833- PEP 3123: Provide forward compatibility with Python 3.0, while
3834 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3835 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3838 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003839
3840- Patch #1733960: Allow T_LONGLONG to accept ints.
3841
3842- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3843
Christian Heimes000a0742008-01-03 22:16:32 +00003844- Added a new API function ``PyImport_ImportModuleNoBlock``.
3845
Georg Brandl6caad7d2008-01-26 14:19:22 +00003846- Bug #1637022: Prefix AST symbols with _Py_.
3847
3848- Fix some leftovers from the conversion from int to Py_ssize_t
3849 (relevant to strings and sequences of more than 2**31 items).
3850
3851- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3852 outside of pystate.c and should not be necessary.
3853
Georg Brandl3ee81df2008-05-17 18:14:43 +00003854- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3855 absolute imports. In earlier versions they might have used relative
3856 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003857
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3859 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003860
Georg Brandl3ee81df2008-05-17 18:14:43 +00003861- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3862 macro so it can be used as an expression.

3867
Georg Brandl3ee81df2008-05-17 18:14:43 +00003868- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3869 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3870 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3871 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003872
Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
3874 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00003884- buildtools now raises a DeprecationWarning.
3885
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886- Removed the macfs module. It had been deprecated since Python 2.5.
3887 This lead to the deprecation of macostools.touched() as it relied
3888 solely on macfs and was a no-op under OS X.
