487What's New in Python 2.6.1
488==========================
489
490*Release date: 04-Dec-2008*
491
492Core and Builtins
493-----------------
494
495- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
496 interpreter to abort ("Fatal Python error: Could not reset the stack!")
497 instead of throwing a MemoryError.
498
499- Issue #4367: Python would segfault during compiling when the unicodedata
500 module couldn't be imported and \N escapes were present.
501
502- Issue #4348: Some bytearray methods returned that didn't cause any change to
503 the bytearray, returned the same bytearray instead of a copy.
504
505- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
506
507- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
508
509- Issue #4048: The parser module now correctly validates relative imports.
510
511- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

513
514- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
515 method does not return iterators for the 4th and 5th items.
516
517- Issue #4209: Enabling unicode_literals and the print_function in the same
518 __future__ import didn't work.
519
520- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
521 returned a path longer than MAX_PATH. (But It's doubtful this code path is
522 really executed because I cannot move to such directory on win2k)
523
524- Issue #4069: When set.remove(element) is used with a set element, the element
525 is temporarily replaced with an equivalent frozenset. But the eventual
526 KeyError would always report the empty frozenset([]) as the missing key. Now
527 it correctly refers to the initial element.
528
529- Fixed C99 style comments in several files. Python is now C89 compatible
530 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000677- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
678
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000679- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
680 PyString_FromFormat or PyErr_Format to display size_t values. The macro
681 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
682 ``printf`` function, whereas PyString_FromFormat has an independent
683 implementation and uses "%zd" on all platforms for size_t values.
684 This makes a difference on win64, where ``printf`` needs "%Id" to display
685 64bit values.
686
Benjamin Peterson97179b02008-09-09 20:55:01 +0000687- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
688 error.
689
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000690- Issue #3777: long() applied to a float object now always return a long
691 object; previously an int would be returned for small values. the __long__
692 method is allowed to return either an int or a long, but the behaviour of
693 float objects should not change to respect backward compatibility.
694
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000695- Issue #3751: str.rpartition would perform a left-partition when called with
696 a unicode argument.
697
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000698- Issue #3683: Fix compilation when --without-threads is given.
699
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000700- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000701 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000702 was correctly parsed but parsing of subsequent arguments failed.
703
Vinay Sajip35e3b032008-09-01 14:33:59 +0000704- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000705 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
706 mechanism. In the process, fix a bug where isinstance() and issubclass(),
707 when given a tuple of classes as second argument, were looking up
708 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
709 type object.
710
Neal Norwitz18aa3882008-08-24 05:04:52 +0000711- Fix crashes on memory allocation failure found with failmalloc.
712
713- Fix memory leaks found with valgrind and update suppressions file.
714
715- Fix compiler warnings in opt mode which would lead to invalid memory reads.
716
717- Fix problem using wrong name in decimal module reported by pychecker.
718
Christian Heimes7d4c3172008-08-22 19:47:25 +0000719- Silenced another compiler warning about a used but not defined
720 function 'stringlib_contains_obj'.
721
Benjamin Peterson712ee922008-08-24 18:10:20 +0000722- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
723 ``__delslice__``.
724
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +0000725- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
726 library targets in the Makefile.
727
Gregory P. Smith980b99b2008-09-07 05:15:18 +0000728- Issue #1204: The configure script now tests for additional libraries
729 that may be required when linking against readline. This fixes issues
730 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +0000740- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
741 stack usage in the case of deeply nested objects.
742
Guido van Rossume3c4fd92008-09-10 14:27:00 +0000743- Issue #3629: Fix sre "bytecode" validator for an end case.

Martin v. Löwis24329ba2008-09-10 13:38:12 +0000745- Issue #3811: The Unicode database was updated to 5.1.
746
Nick Coghland2e09382008-09-11 12:11:06 +0000747- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
748 silent misbehaviour when a single instance is nested in multiple
749 with statements, or when the methods are invoked in the wrong order.
750
Vinay Sajip844f7412008-09-09 13:42:08 +0000751- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
752
Nick Coghland2e09382008-09-11 12:11:06 +0000753- Issue #3781: Clean up the API for warnings.catch_warnings() by having it

Brett Cannon32476fc2008-09-05 18:33:51 +0000761
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +0000762- Issue #3762: platform.architecture() fails if python is lanched via
763 its symbolic link.

777 path to the Python binary.
778
Brett Cannon1eaf0742008-09-02 01:25:16 +0000779- Issue 3602: Moved test.test_support.catch_warning() to
780 warnings.catch_warnings() along with some API cleanup. Expanding the tests
781 for catch_warnings() also led to an improvement in the raising of a
782 DeprecationWarning related to warnings.warn_explicit().
783
Benjamin Peterson973e6c22008-09-01 23:12:58 +0000784- The deprecation warnings for the old camelCase threading API were removed.
785

802-----------------
803
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000804- Issue #2975: When compiling several extension modules with Visual Studio 2008
805 from the same python interpreter, some environment variables would grow
806 without limit.
807

Gerhard Häring6e1afcf2008-09-12 18:58:57 +0000813- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
814 remaining ones have "pysqlite_" prefix.
815
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000816- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000845What's New in Python 2.6 beta 3?
846================================
847
Barry Warsaw07a4a382008-08-21 01:15:08 +0000848*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000849
850Core and Builtins
851-----------------
852
Guido van Rossumf8402962008-08-20 15:01:50 +0000853- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
854 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
855 extensions do not automatically benefit from the class attribute
856 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
857 to their tp_flags field if they care. This is a backwards
858 compatibility feature; in 3.0, all types will use the cache by
859 default.
860
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000861- Keyword arguments can now follow starred arguments. (``f(a, *args,
862 keyword=23)`` is now valid syntax.)
863
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000864- ctypes function pointers that are COM methods have a boolean True
865 value again.
866
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000867- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
868 by denying s# to parse objects that have a releasebuffer procedure,
869 and introducing s*.
870
Georg Brandl1e13ea92008-08-11 09:07:59 +0000871- Issue #3537: Fix an assertion failure when an empty but presized dict
872 object was stored in the freelist.
873
Mark Dickinsonb6467572008-08-04 21:30:09 +0000874- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
875 ValueError consistently across platforms.
876
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000877- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
878 (64bit Unix, for example), unichr() would truncate its argument and return
879 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
880
Neal Norwitze7d8be82008-07-31 17:17:14 +0000881- Apply security patches from Apple.
882
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000883- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
884 PyErr_ExceptionMatches returns 0 when an exception occurs there.
885
Antoine Pitrou92f82162008-07-25 22:22:08 +0000886- Issue #1819: function calls with several named parameters are now on
887 average 35% faster (as measured by pybench).
888
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000889- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
890 the python debugger steps into a class statement: the free variables (local
891 variables defined in an outer scope) would be deleted from the outer scope.
892
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000893- Issue #2620: Overflow checking when allocating or reallocating memory
894 was not always being done properly in some python types and extension
895 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
896 all been updated to perform better checks and places in the code that
897 would previously leak memory on the error path when such an allocation
898 failed have been fixed.

907
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000908- Issue #2234: distutils failed for some versions of the cygwin compiler. The
909 version reported by these tools does not necessarily follow the python
910 version numbering scheme, so the module is less strict when parsing it.
911
Nick Coghlanf70385a2008-08-18 12:42:46 +0000912- Issue #2235: Added Py3k warnings for types which will become unhashable
913 under the stricter __hash__ inheritance rules in 3.0. Several types
914 which did not meet the rules for hash invariants and were already
915 unhashable in 3.0 have now been explicitly flagged as unhashable in
916 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
917 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
918
Brett Cannon88f801d2008-08-18 00:46:22 +0000919- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

927
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000928- Issue #3575: Incremental decoder's decode function now takes bytearray
929 by using 's*' instead of 't#'.
930
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000931- Issue #2222: Fixed reference leak when occured os.rename()
932 fails unicode conversion on 2nd parameter. (windows only)
933
Facundo Batista94f243a2008-08-17 03:38:39 +0000934- Issue 2464. urllib2 now supports a malformation in the URL received
935 in a redirect.
936
Brett Cannonabe423e2008-08-16 21:47:07 +0000937- Silence the DeprecationWarning raised when importing mimetools in

Brett Cannonabe423e2008-08-16 21:47:07 +0000939
Facundo Batistaeb90b782008-08-16 14:44:07 +0000940- Issue #2776: fixed small issue when handling an URL with double slash
941 after a 302 response in the case of not going through a proxy.
942
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000943- Issue #2676: in the email package, content-type parsing was hanging on
944 pathological input because of quadratic or exponential behaviour of a
945 regular expression.
946
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000947- Issue #3476: binary buffered reading through the new "io" library is now
948 thread-safe.
949
Brett Cannonbf3157b2008-08-14 05:00:03 +0000950- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
951 since mimetools itself is deprecated. Because modules are cached, all
952 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
953
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000954- Issue #3134: shutil referenced undefined WindowsError symbol.
955
Robert Schuppenies14646332008-08-10 11:01:53 +0000956- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
957 menu entries were not deleted.
958
Brett Cannon83e81842008-08-09 23:30:55 +0000959- Copied the implementation of reduce() to _functools.reduce() to have a
960 version that did not raise a DeprecationWarning under -3.
961
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000962- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
963 a MemoryError rather than silently stop the iteration.
964
Guido van Rossum59ce9012008-08-09 14:55:34 +0000965- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
966 to _sre.compile() will now be rejected. This should not affect anybody
967 since the re.compile() function never generates invalid re-bytecode.
968
Skip Montanaroa032bf42008-08-08 22:52:51 +0000969- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
970 upon first access it can be automatically initialized from the csv file if
971 it wasn't initialized during instantiation.
972
Brett Cannon3aa2a492008-08-06 22:28:09 +0000973- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
974 the reload() built-in has been removed.
975

Antoine Pitroude781a42008-08-09 12:43:23 +0000988 asking for a specific length. This problem only affected files opened

1015 file name rather than a ZipInfo instance, so files are extracted with
1016 mode 0600 rather than 000 under Unix.
1017
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001018- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1032
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001033- Issue #643841: The language reference now provides more detailed

1041
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001042*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001044Core and Builtins
1045-----------------
1046
Georg Brandl3e483f62008-07-16 22:57:41 +00001047- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1048 its methods now allow for items objects that can be converted to
1049 an integer using operator.index().
1050
Mark Dickinson64b7e502008-07-16 09:40:03 +00001051- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1052 produced a ValueError instead of giving the correct float.
1053
Eric Smitha5fa5a22008-07-16 00:11:49 +00001054- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1055 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1056
Mark Dickinson7103aa42008-07-15 19:08:33 +00001057- Issue #3008: the float type has a new instance method 'float.hex'
1058 and a new class method 'float.fromhex' to convert floating-point
1059 numbers to and from hexadecimal strings, respectively.
1060
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001061- Issue #2235: __hash__ is once again inherited by default. To allow
1062 collections.Hashable to remain meaningful in the presence of the
1063 default hash implementation (object.__hash__), it is now possible
1064 to explicit block inheritance of hash by setting __hash__=None at
1065 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1066 level.
1067
Nick Coghlanb028f502008-07-13 14:52:36 +00001068- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1069 the parent module cannot be found while performing an absolute import.
1070 This means that an incorrectly defined __package__ attribute will
1071 now only prevent relative imports in that module rather than causing
1072 all imports from that module to fail.
1073
Nick Coghlan14ff9942008-07-08 14:21:42 +00001074- Issue #2517: Allow unicode messages in Exceptions again by correctly
1075 bypassing the instance dictionary when looking up __unicode__ on
1076 new-style classes.

1083 threading.local: the first member set by a thread could be saved in
1084 another thread's dictionary.
1085
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001086- Issue #3004: Minor change to slice.indices(): the start and stop
1087 arguments are now treated identically, making the behaviour easier
1088 to describe and understand. For example, slice(None, -10,
1089 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1090 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1091 10, -1).
1092
Georg Brandl278fc502008-07-19 12:46:12 +00001093- Issue #3219: Calling a function with repeated keyword arguments,
1094 f(a=2, a=23), would not cause a syntax error. This was a regression
1095 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001096
Georg Brandl278fc502008-07-19 12:46:12 +00001097- Issue #2862: Make int and float freelist management consistent with
1098 other freelists. Changes their CompactFreeList apis into
1099 ClearFreeList apis and calls them via gc.collect().

1105 api functions without holding the GIL, which could lead to a fatal
1106 error when they failed.
1107
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001108- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001133- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1134 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001135 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001136 content-length. The problem had been corrected in the 2.4 branch, but never
1137 merged into trunk.
1138
Georg Brandle78fbcc2008-07-05 10:13:36 +00001139- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001152- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1153 handling is now the same as that of other special attributes like __name__).
1154
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001155- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00001543- On MacOS X it is now possible to install the framework in 64-bit
1544 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001545 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001546
1547 This is controlled by the configure argument ``--with-universal-archs``:
1548
1549 - ``--with-universal-archs=all``: install 4-way universal
1550
1551 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1552
1553 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1554
1555 This option should be used in combination with ``--enable-universalsdk=``.
1556
1557 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

1562
Georg Brandl74a1dea2008-05-28 11:21:39 +00001563- Add ``PyType_Modified()`` as a public API to clear the type cache.
1564
1565- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00001566
1567- The PyString functions have been renamed to PyBytes. A batch of
1568 defines were added so that the linker still sees the original
1569 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001607- Issue #1631171: Re-implement the 'warnings' module in C (the
1608 original Python code has been kept as backup). This will allow for
1609 using the 'warning's machinery in such places as the parser where
1610 use of pure Python code is not possible. Both the ``showarning()``
1611 and ``formatwarning()`` gain an optional 'line' argument which is
1612 not called by default for backwards-compatibility reasons. Setting
1613 ``warnings.showwarning()`` to an implementation that lacks support
1614 for the ``line`` argument will raise a DeprecationWarning.

1638
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001639- The getpass module has been improved on Unix. It now uses /dev/tty
1640 by default and uses stderr instead of stdout. A GetPassWarning is
1641 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001656- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001657 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001677- Issue #2550: The approach used by client/server code for obtaining
1678 ports to listen on in network-oriented tests has been refined in an
1679 effort to facilitate running multiple instances of the entire
1680 regression test suite in parallel without issue.
1681 test_support.bind_port() has been fixed such that it will always
1682 return a unique port -- which wasn't always the case with the
1683 previous implementation, especially if socket options had been set
1684 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1685 new implementation of bind_port() will actually raise an exception
1686 if it is passed an AF_INET/SOCK_STREAM socket with either the
1687 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1688 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1689 the socket it's been passed. This currently only applies to
1690 Windows. This option prevents any other sockets from binding to the
1691 host/port we've bound to, thus removing the possibility of the
1692 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1693 when a second SOCK_STREAM socket binds and accepts to a host/port
1694 that's already been bound by another socket. The optional preferred
1695 port parameter to bind_port() has been removed. Under no
1696 circumstances should tests be hard coding ports!
1697
1698 test_support.find_unused_port() has also been introduced, which will
1699 pass a temporary socket object to bind_port() in order to obtain an
1700 unused port. The temporary socket object is then closed and
1701 deleted, and the port is returned. This method should only be used
1702 for obtaining an unused port in order to pass to an external program
1703 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1704 a parameter to a server-oriented class that doesn't give you direct
1705 access to the underlying socket used.
1706
1707 Finally, test_support.HOST has been introduced, which should be used
1708 for the host argument of any relevant socket calls (i.e. bind and
1709 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001710
1711 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001712 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001713 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1714 test_asynchat and test_socket_ssl.
1715
Georg Brandl3ee81df2008-05-17 18:14:43 +00001716 It is now possible for multiple instances of the regression test
1717 suite to run in parallel without issue.

1984-----------------
1985
Fred Drakea8ee94b2008-03-01 02:45:07 +00001986- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001987 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00001993- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001994 issue 215555 for a discussion.
1995
Eric Smitha73fbe72008-02-23 03:09:44 +00001996- Added the future_builtins module, which contains hex() and oct().
1997 These are the PEP 3127 version of these functions, designed to be
1998 compatible with the hex() and oct() builtins from Python 3.0. They
1999 differ slightly in their output formats from the existing, unchanged
2000 Python 2.6 builtins. The expected usage of the future_builtins
2001 module is:
2002 from future_builtins import hex, oct
2003
Eric Smith7ef40bf2008-02-20 23:34:22 +00002004- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2005 exponents for exponents with absolute value < 100. Follows C99
2006 standard. This is a change on Windows, which would use 3 digits.
2007 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2008 so that any alterations it does to the resulting string will be
2009 available in stringlib/formatter.h (for float.__format__).
2010
Eric Smith5a3c1352008-02-19 13:21:56 +00002011- Implemented PEP 3101, Advanced String Formatting. This adds a new
2012 builtin format(); a format() method for str and unicode; a
2013 __format__() method to object, str, unicode, int, long, float, and
2014 datetime; the class string.Formatter; and the C API
2015 PyObject_Format().
2016
Georg Brandl3ee81df2008-05-17 18:14:43 +00002017- Fixed several potential crashes, all caused by specially crafted
2018 __del__ methods exploiting objects in temporarily inconsistent
2019 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002020
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002021- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002022 prevent a possible crash: an Abstract Base Class would try to access
2023 a slot on a registered virtual subclass.

2030 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002031
Georg Brandl3ee81df2008-05-17 18:14:43 +00002032- Issue #2045: Fix an infinite recursion triggered when printing a
2033 subclass of collections.defaultdict, if its default_factory is set
2034 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002035
Christian Heimesf75dbef2008-02-08 00:11:31 +00002036- Fixed a minor memory leak in dictobject.c. The content of the free
2037 list was not freed on interpreter shutdown.
2038
Georg Brandl3ee81df2008-05-17 18:14:43 +00002039- Limit free list of method and builtin function objects to 256
2040 entries each.

2043 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002044 to compact the internal free lists of pre-allocted ints and floats.
2045
Georg Brandl3ee81df2008-05-17 18:14:43 +00002046- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2047 calls. Python expected the return type int but the fork familie
2048 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002049

Georg Brandl3ee81df2008-05-17 18:14:43 +00002062- Patch #1473257: generator objects gain a gi_code attribute. This is
2063 the same object as the func_code attribute of the function that
2064 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002065
Georg Brandl3ee81df2008-05-17 18:14:43 +00002066- Issue #1920: "while 0" statements were completely removed by the
2067 compiler, even in the presence of an "else" clause, which is
2068 supposed to be run when the condition is false. Now the compiler
2069 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002070
Guido van Rossumeead05f2008-01-24 18:21:02 +00002071- A few crashers fixed: weakref_in_del.py (issue #1377858);
2072 loosing_dict_ref.py (issue #1303614, test67.py);
2073 borrowed_ref_[34].py (not in tracker).
2074
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002075- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002076 suppressed while an extension is loaded by calling SetErrorMode in
2077 dynload_win.c. The error is still reported properly.
2078
Georg Brandl3ee81df2008-05-17 18:14:43 +00002079- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002080 several extension methods and modules do not work without unicode
2081 support.
2082
Georg Brandl26543b12008-01-21 18:36:51 +00002083- Issue #1882: when compiling code from a string, encoding cookies in the
2084 second line of code were not always recognized correctly.
2085
Georg Brandl14404b62008-01-19 19:27:05 +00002086- Issue #1679: "0x" was taken as a valid integer literal.
2087
Georg Brandl6caad7d2008-01-26 14:19:22 +00002088- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002089 added.
2090
Christian Heimesc94e2b52008-01-14 04:13:37 +00002091- sys.float_info / PyFloat_GetInfo: The floating point information
2092 object was converted from a dict to a specialized structseq object.
2093
Georg Brandl3ee81df2008-05-17 18:14:43 +00002094- Patch #1816: Added sys.flags structseq. It exposes the status of
2095 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002096
Georg Brandl3ee81df2008-05-17 18:14:43 +00002097- Objects/structseq.c: Implemented new structseq representation. The
2098 patch makes structseqs (e.g. the return value of os.stat) more
2099 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Patch #1700288: added a type attribute cache that caches method
2102 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002103
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002104- Bug #1776: __import__() no longer accepts filenames on any platform.
2105 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002106
Georg Brandlaed6c662008-01-07 17:25:53 +00002107- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2108
Georg Brandl3ee81df2008-05-17 18:14:43 +00002109- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2110 envvar and sys.dont_write_bytecode attribute. All these can be set
2111 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002112
Georg Brandl3ee81df2008-05-17 18:14:43 +00002113- Improve some exception messages when Windows fails to load an
2114 extension module. Now we get for example '%1 is not a valid Win32
2115 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002116
Georg Brandl3ee81df2008-05-17 18:14:43 +00002117- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002119- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2120 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002121
Christian Heimes0a8143f2007-12-18 23:22:54 +00002122- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002123 and INF. float("nan"), float("inf") and float("-inf") now work on
2124 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002125
Georg Brandl3ee81df2008-05-17 18:14:43 +00002126- Compiler now generates simpler and faster code for dictionary
2127 literals. The oparg for BUILD_MAP now indicates an estimated
2128 dictionary size. There is a new opcode, STORE_MAP, for adding
2129 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002130
Georg Brandl3ee81df2008-05-17 18:14:43 +00002131- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002136- Issue #1538: Avoid copying string in split/rsplit if the split char
2137 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002138
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002139- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002140 SystemError.
2141
Nick Coghlanef01d822007-12-03 12:55:17 +00002142- PEP 366: Allow explicit relative imports when executing modules

2147 running, and if the deallocation of its frames somehow calls the
2148 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002149

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002153 attribute of an empty cell object.
2154
Georg Brandl3ee81df2008-05-17 18:14:43 +00002155- Issue #1460: The utf-7 incremental decoder did not accept truncated
2156 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002157
Georg Brandl3ee81df2008-05-17 18:14:43 +00002158- Patch #1739468: Directories and zipfiles containing a __main__.py
2159 file can now be directly executed by passing their name to the
2160 interpreter. The directory/zipfile is automatically inserted as the
2161 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002162
Georg Brandl3ee81df2008-05-17 18:14:43 +00002163- Issue #1265: Fix a problem with sys.settrace, if the tracing
2164 function uses a generator expression when at the same time the
2165 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002166
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002167- sets and frozensets now have an isdisjoint() method.
2168
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002169- optimize the performance of builtin.sum().
2170
Neal Norwitz44f326e2007-10-05 05:29:17 +00002171- Fix warnings found by the new version of the Coverity checker.
2172
Georg Brandl3ee81df2008-05-17 18:14:43 +00002173- The enumerate() builtin function is no longer bounded to sequences
2174 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2175 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002176
Georg Brandl3ee81df2008-05-17 18:14:43 +00002177- Issue #1686386: Tuple's tp_repr did not take into account the
2178 possibility of having a self-referential tuple, which is possible
2179 from C code. Nor did object's tp_str consider that a type's tp_str
2180 could do something that could lead to an inifinite recursion.
2181 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2182 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002183
Georg Brandl3ee81df2008-05-17 18:14:43 +00002184- Issue #1164: It was possible to trigger deadlock when using the
2185 'print' statement to write to a file since the GIL was not released
2186 as needed. Now PyObject_Print() does the right thing along with
2187 various tp_print implementations of the built-in types and those in
2188 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002189
Georg Brandl3ee81df2008-05-17 18:14:43 +00002190- Issue #1147: Exceptions were directly allowing string exceptions in
2191 their throw() method even though string exceptions no longer
2192 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002193
Georg Brandl3ee81df2008-05-17 18:14:43 +00002194- Issue #1096: Prevent a segfault from getting the repr of a very
2195 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002196
Brett Cannon1e534b52007-09-07 04:18:30 +00002197- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002198 PyObject_Call() never calling back out to Python code to trigger
2199 recursion depth updates/checks. Required the creation of a static
2200 RuntimeError instance in case normalizing an exception put the
2201 recursion check value past its limit. Fixes crashers
2202 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002203
Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- Patch #1031213: Decode source line in SyntaxErrors back to its

2208 with %G.
2209
Georg Brandl3ee81df2008-05-17 18:14:43 +00002210- Prevent expandtabs() on string and unicode objects from causing a
2211 segfault when a large width is passed on 32-bit platforms.

Georg Brandla5ea6892007-06-01 11:33:33 +00002216
Neal Norwitz0ac60192007-05-27 04:08:54 +00002217- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218 __*__ attributes. (Some already existed, e.g., __doc__ and
2219 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002220
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002221- Add -3 option to the interpreter to warn about features that are
2222 deprecated and will be changed/removed in Python 3.0.
2223
Georg Brandl2134e752007-05-21 20:34:16 +00002224- Patch #1686487: you can now pass any mapping after '**' in function
2225 calls.
2226
Collin Winter62903052007-05-18 23:11:24 +00002227- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002228 "except E as target:". This is to provide forwards compatibility
2229 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002230
Brett Cannon229cee22007-05-05 01:34:02 +00002231- Deprecate BaseException.message as per PEP 352.
2232
Georg Brandl3ee81df2008-05-17 18:14:43 +00002233- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002234 inherited from a builtin base.
2235
Vinay Sajip8549ce32007-05-06 17:53:37 +00002236- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002237 setting a plain string, ie don't expand to single letter identifiers.
2238
Raymond Hettinger13936692007-04-11 18:40:58 +00002239- Request #1191699: Slices can now be pickled.
2240
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002241- Request #1193128: str.translate() now allows a None argument for
2242 translations that only remove characters without re-mapping the
2243 remaining characters.
2244
Georg Brandl5cb76c12007-03-21 09:00:39 +00002245- Patch #1682205: a TypeError while unpacking an iterable is no longer
2246 masked by a generic one with the message "unpack non-sequence".
2247
Neal Norwitzaa754b72007-03-21 06:39:48 +00002248- Remove unused file Python/fmod.c.
2249
Guido van Rossum143b5642007-03-23 04:58:42 +00002250- Bug #1683368: The object.__init__() and object.__new__() methods are
2251 now stricter in rejecting excess arguments. The only time when
2252 either allows excess arguments is when it is not overridden and the
2253 other one is. For backwards compatibility, when both are
2254 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002255 warning later). Also, type.__init__() insists on the same signature
2256 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002257
Georg Brandl3ee81df2008-05-17 18:14:43 +00002258- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2259 object to complex using its __complex__() method before falling back
2260 to the __float__() method. Therefore, the functions in the cmath
2261 module now can operate on objects that define a __complex__()
2262 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002263
Georg Brandl3ee81df2008-05-17 18:14:43 +00002264- Patch #1623563: allow __class__ assignment for classes with
2265 __slots__. The old and the new class are still required to have the
2266 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002267
Georg Brandl3ee81df2008-05-17 18:14:43 +00002268- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Patch #1462488: Python no longer segfaults when
2272 ``object.__reduce_ex__()`` is called with an object that is faking
2273 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002278- Patch #1444529: the builtin compile() now accepts keyword arguments.
2279
Georg Brandl7b9c5552007-03-12 14:30:05 +00002280- Bug #1678647: write a newline after printing an exception in any
2281 case, even when converting the value to a string failed.
2282
Georg Brandl871f1bc2007-03-12 13:17:36 +00002283- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002284 its argument, if it exists. If not, it will work like before. This
2285 allows customizing the output of dir() in the presence of a
2286 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002287
Collin Winter276887b2007-03-12 16:11:39 +00002288- Patch #922167: Python no longer segfaults when faced with infinitely
2289 self-recursive reload() calls (as reported by bug #742342).
2290
Georg Brandl3ee81df2008-05-17 18:14:43 +00002291- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002294- Patch #1491866: change the complex() constructor to allow
2295 parthensized forms. This means complex(repr(x)) now works instead of
2296 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002297
Georg Brandlaa2321b2007-03-07 00:40:28 +00002298- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002299 makes the filenames the warning module prints much more sensible
2300 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002301

2808
Facundo Batistad918a652007-04-24 13:54:38 +00002809- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002810 the client's request was successfully received, understood, and
2811 accepted. Now in these cases no error is raised in urllib (issue
2812 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00002813

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00002820- Added a timeout parameter to the constructor of other protocols
2821 (telnetlib, ftplib, smtplib and poplib). This is second part of the
2822 work started with create_connection() and timeout in httplib, and
2823 closes patch #723312.
2824
Vinay Sajip8549ce32007-05-06 17:53:37 +00002825- Patch #1676823: Added create_connection() to socket.py, which may be
2826 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00002827 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00002828
Martin v. Löwis0af33882007-03-23 13:27:15 +00002829- Bug #978833: Revert r50844, as it broke _socketobject.dup.

2849
Georg Brandlf66b6032007-03-14 08:27:52 +00002850- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851 AttributeError instead of an IOError when the server's response
2852 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002853
Georg Brandl3ee81df2008-05-17 18:14:43 +00002854- Patch #957650: "%var%" environment variable references are now
2855 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00002857
Georg Brandl3ee81df2008-05-17 18:14:43 +00002858- Patch #1429539: pdb now correctly initializes the __main__ module
2859 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002860 correctly now.
2861
Georg Brandlbad6f192007-03-13 21:32:56 +00002862- The nonobvious commands.getstatus() function is now deprecated.

2868
Georg Brandl3ee81df2008-05-17 18:14:43 +00002869- Patch #1530482: add pydoc.render_doc() which returns the
2870 documentation for a thing instead of paging it to stdout, which
2871 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00002872
Georg Brandl3ee81df2008-05-17 18:14:43 +00002873- Patch #1533909: the timeit module now accepts callables in addition

2880 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00002882- Patch #1581073: add a flag to textwrap that prevents the dropping of

2884
Georg Brandl92a6bae2007-03-13 17:43:32 +00002885- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886 are set for invalid interpolation sequences that would lead to
2887 errors on reading back those values.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002903 field names in its exception message if you try to write a record
2904 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00002922

2930 returned string up to the first NUL character.
2931

2941
Georg Brandl3ee81df2008-05-17 18:14:43 +00002942- unittest now verifies more of its assumptions. In particular,
2943 TestCase and TestSuite subclasses (not instances) are no longer
2944 accepted in TestSuite.addTest(). This should cause no
2945 incompatibility since it never made sense with ordinary subclasses
2946 -- the failure just occurred later, with a more cumbersome
2947 exception.

2956 given a unicode argument and os.listdir() returns unicode filenames.
2957
Georg Brandl3ee81df2008-05-17 18:14:43 +00002958- Patch #1673619: setup.py identifies extension modules it doesn't

2960 build.

3318 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3319 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003336 time so that opening a database previously created with the DB_DUP
3337 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3338 opens. Specifically: dictionary assignment to a DB object will
3339 replace all values for a given key when the database allows
3340 duplicate values. DB users should use DB.put(k, v) when they want
3341 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003342

3348 characters with ASCII value less than 32. Also, it correctly quotes
3349 dots only if they occur on a single line, as opposed to the previous
3350 behavior of quoting dots if they are the second character of any
3351 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003352
