499What's New in Python 2.6.1
500==========================
501
502*Release date: 04-Dec-2008*
503
504Core and Builtins
505-----------------
506
507- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
508 interpreter to abort ("Fatal Python error: Could not reset the stack!")
509 instead of throwing a MemoryError.
510
511- Issue #4367: Python would segfault during compiling when the unicodedata
512 module couldn't be imported and \N escapes were present.
513
514- Issue #4348: Some bytearray methods returned that didn't cause any change to
515 the bytearray, returned the same bytearray instead of a copy.
516
517- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
518
519- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
520
521- Issue #4048: The parser module now correctly validates relative imports.
522
523- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
524 exec statement.
525
526- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
527 method does not return iterators for the 4th and 5th items.
528
529- Issue #4209: Enabling unicode_literals and the print_function in the same
530 __future__ import didn't work.
531
532- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
533 returned a path longer than MAX_PATH. (But It's doubtful this code path is
534 really executed because I cannot move to such directory on win2k)
535
536- Issue #4069: When set.remove(element) is used with a set element, the element
537 is temporarily replaced with an equivalent frozenset. But the eventual
538 KeyError would always report the empty frozenset([]) as the missing key. Now
539 it correctly refers to the initial element.
540
541- Fixed C99 style comments in several files. Python is now C89 compatible
542 again.

687-----------------
688
Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000689- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
690
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000691- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
692 PyString_FromFormat or PyErr_Format to display size_t values. The macro
693 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
694 ``printf`` function, whereas PyString_FromFormat has an independent
695 implementation and uses "%zd" on all platforms for size_t values.
696 This makes a difference on win64, where ``printf`` needs "%Id" to display
697 64bit values.
698
Benjamin Peterson97179b02008-09-09 20:55:01 +0000699- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
700 error.
701
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000702- Issue #3777: long() applied to a float object now always return a long
703 object; previously an int would be returned for small values. the __long__
704 method is allowed to return either an int or a long, but the behaviour of
705 float objects should not change to respect backward compatibility.
706
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000707- Issue #3751: str.rpartition would perform a left-partition when called with
708 a unicode argument.
709
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000710- Issue #3683: Fix compilation when --without-threads is given.
711
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000712- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000713 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000714 was correctly parsed but parsing of subsequent arguments failed.
715
Vinay Sajip35e3b032008-09-01 14:33:59 +0000716- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000717 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
718 mechanism. In the process, fix a bug where isinstance() and issubclass(),
719 when given a tuple of classes as second argument, were looking up
720 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
721 type object.
722
Neal Norwitz18aa3882008-08-24 05:04:52 +0000723- Fix crashes on memory allocation failure found with failmalloc.
724
725- Fix memory leaks found with valgrind and update suppressions file.
726
727- Fix compiler warnings in opt mode which would lead to invalid memory reads.
728
729- Fix problem using wrong name in decimal module reported by pychecker.
730
Christian Heimes7d4c3172008-08-22 19:47:25 +0000731- Silenced another compiler warning about a used but not defined
732 function 'stringlib_contains_obj'.
733
Benjamin Peterson712ee922008-08-24 18:10:20 +0000734- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
735 ``__delslice__``.
736
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +0000737- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
738 library targets in the Makefile.
739
Gregory P. Smith980b99b2008-09-07 05:15:18 +0000740- Issue #1204: The configure script now tests for additional libraries
741 that may be required when linking against readline. This fixes issues
742 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
743

753 stack usage in the case of deeply nested objects.
754

Martin v. Löwis24329ba2008-09-10 13:38:12 +0000757- Issue #3811: The Unicode database was updated to 5.1.
758
Nick Coghland2e09382008-09-11 12:11:06 +0000759- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
760 silent misbehaviour when a single instance is nested in multiple
761 with statements, or when the methods are invoked in the wrong order.
762
Vinay Sajip844f7412008-09-09 13:42:08 +0000763- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
764
Nick Coghland2e09382008-09-11 12:11:06 +0000765- Issue #3781: Clean up the API for warnings.catch_warnings() by having it

792 warnings.catch_warnings() along with some API cleanup. Expanding the tests
793 for catch_warnings() also led to an improvement in the raising of a
794 DeprecationWarning related to warnings.warn_explicit().
795
Benjamin Peterson973e6c22008-09-01 23:12:58 +0000796- The deprecation warnings for the old camelCase threading API were removed.
797

Benjamin Peterson37346b22008-08-23 20:27:43 +0000813Extension Modules
814-----------------
815
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000816- Issue #2975: When compiling several extension modules with Visual Studio 2008

827
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000828- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000857What's New in Python 2.6 beta 3?
858================================
859
Barry Warsaw07a4a382008-08-21 01:15:08 +0000860*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000861
862Core and Builtins
863-----------------
864
Guido van Rossumf8402962008-08-20 15:01:50 +0000865- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
866 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
867 extensions do not automatically benefit from the class attribute
868 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
869 to their tp_flags field if they care. This is a backwards
870 compatibility feature; in 3.0, all types will use the cache by
871 default.
872
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000873- Keyword arguments can now follow starred arguments. (``f(a, *args,
874 keyword=23)`` is now valid syntax.)
875
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000876- ctypes function pointers that are COM methods have a boolean True
877 value again.
878
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000879- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
880 by denying s# to parse objects that have a releasebuffer procedure,
881 and introducing s*.
882
Georg Brandl1e13ea92008-08-11 09:07:59 +0000883- Issue #3537: Fix an assertion failure when an empty but presized dict
884 object was stored in the freelist.
885
Mark Dickinsonb6467572008-08-04 21:30:09 +0000886- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
887 ValueError consistently across platforms.
888
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000889- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
890 (64bit Unix, for example), unichr() would truncate its argument and return
891 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
892
Neal Norwitze7d8be82008-07-31 17:17:14 +0000893- Apply security patches from Apple.
894
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000895- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
896 PyErr_ExceptionMatches returns 0 when an exception occurs there.
897
Antoine Pitrou92f82162008-07-25 22:22:08 +0000898- Issue #1819: function calls with several named parameters are now on
899 average 35% faster (as measured by pybench).
900
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000901- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
902 the python debugger steps into a class statement: the free variables (local
903 variables defined in an outer scope) would be deleted from the outer scope.
904
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000905- Issue #2620: Overflow checking when allocating or reallocating memory
906 was not always being done properly in some python types and extension
907 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
908 all been updated to perform better checks and places in the code that
909 would previously leak memory on the error path when such an allocation
910 failed have been fixed.
911
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000912Library
913-------
914

Benjamin Petersone977ad42008-08-20 01:42:01 +0000917- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
918 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
919
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000920- Issue #2234: distutils failed for some versions of the cygwin compiler. The
921 version reported by these tools does not necessarily follow the python
922 version numbering scheme, so the module is less strict when parsing it.
923
Nick Coghlanf70385a2008-08-18 12:42:46 +0000924- Issue #2235: Added Py3k warnings for types which will become unhashable
925 under the stricter __hash__ inheritance rules in 3.0. Several types
926 which did not meet the rules for hash invariants and were already
927 unhashable in 3.0 have now been explicitly flagged as unhashable in
928 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
929 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
930
Brett Cannon88f801d2008-08-18 00:46:22 +0000931- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
932 imported into the module but exposed as part of the module's API.
933
Brett Cannon7b96f072008-08-18 00:41:11 +0000934- Remove an unneeded import of abc.ABCMeta from 'inspect'.

939
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000940- Issue #3575: Incremental decoder's decode function now takes bytearray
941 by using 's*' instead of 't#'.
942
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000943- Issue #2222: Fixed reference leak when occured os.rename()
944 fails unicode conversion on 2nd parameter. (windows only)
945
Facundo Batista94f243a2008-08-17 03:38:39 +0000946- Issue 2464. urllib2 now supports a malformation in the URL received
947 in a redirect.
948
Brett Cannonabe423e2008-08-16 21:47:07 +0000949- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000950 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000951
Facundo Batistaeb90b782008-08-16 14:44:07 +0000952- Issue #2776: fixed small issue when handling an URL with double slash
953 after a 302 response in the case of not going through a proxy.
954
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000955- Issue #2676: in the email package, content-type parsing was hanging on
956 pathological input because of quadratic or exponential behaviour of a
957 regular expression.
958
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000959- Issue #3476: binary buffered reading through the new "io" library is now
960 thread-safe.
961
Brett Cannonbf3157b2008-08-14 05:00:03 +0000962- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
963 since mimetools itself is deprecated. Because modules are cached, all
964 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
965
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000966- Issue #3134: shutil referenced undefined WindowsError symbol.
967
Robert Schuppenies14646332008-08-10 11:01:53 +0000968- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
969 menu entries were not deleted.
970
Brett Cannon83e81842008-08-09 23:30:55 +0000971- Copied the implementation of reduce() to _functools.reduce() to have a
972 version that did not raise a DeprecationWarning under -3.
973
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000974- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
975 a MemoryError rather than silently stop the iteration.
976
Guido van Rossum59ce9012008-08-09 14:55:34 +0000977- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
978 to _sre.compile() will now be rejected. This should not affect anybody

Antoine Pitroude781a42008-08-09 12:43:23 +00001000 asking for a specific length. This problem only affected files opened

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001051What's New in Python 2.6 beta 2?
1052================================
1053
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001054*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001056Core and Builtins
1057-----------------
1058
Georg Brandl3e483f62008-07-16 22:57:41 +00001059- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1060 its methods now allow for items objects that can be converted to
1061 an integer using operator.index().
1062
Mark Dickinson64b7e502008-07-16 09:40:03 +00001063- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1064 produced a ValueError instead of giving the correct float.
1065
Eric Smitha5fa5a22008-07-16 00:11:49 +00001066- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1067 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1068
Mark Dickinson7103aa42008-07-15 19:08:33 +00001069- Issue #3008: the float type has a new instance method 'float.hex'
1070 and a new class method 'float.fromhex' to convert floating-point
1071 numbers to and from hexadecimal strings, respectively.
1072
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001073- Issue #2235: __hash__ is once again inherited by default. To allow
1074 collections.Hashable to remain meaningful in the presence of the
1075 default hash implementation (object.__hash__), it is now possible
1076 to explicit block inheritance of hash by setting __hash__=None at
1077 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1078 level.
1079
Nick Coghlanb028f502008-07-13 14:52:36 +00001080- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1081 the parent module cannot be found while performing an absolute import.
1082 This means that an incorrectly defined __package__ attribute will
1083 now only prevent relative imports in that module rather than causing
1084 all imports from that module to fail.
1085
Nick Coghlan14ff9942008-07-08 14:21:42 +00001086- Issue #2517: Allow unicode messages in Exceptions again by correctly

1096 another thread's dictionary.
1097
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001098- Issue #3004: Minor change to slice.indices(): the start and stop
1099 arguments are now treated identically, making the behaviour easier
1100 to describe and understand. For example, slice(None, -10,
1101 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1102 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1103 10, -1).
1104
Georg Brandl278fc502008-07-19 12:46:12 +00001105- Issue #3219: Calling a function with repeated keyword arguments,
1106 f(a=2, a=23), would not cause a syntax error. This was a regression
1107 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001108
Georg Brandl278fc502008-07-19 12:46:12 +00001109- Issue #2862: Make int and float freelist management consistent with
1110 other freelists. Changes their CompactFreeList apis into

1117 api functions without holding the GIL, which could lead to a fatal
1118 error when they failed.
1119
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001120- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001145- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1146 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001147 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001148 content-length. The problem had been corrected in the 2.4 branch, but never
1149 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001164- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1552
Brett Cannonb61d8012008-05-11 23:39:04 +00001553- ``Lib/lib-old`` is now added to sys.path.
1554
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001555- On MacOS X it is now possible to install the framework in 64-bit
1556 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001557 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001558
1559 This is controlled by the configure argument ``--with-universal-archs``:
1560
1561 - ``--with-universal-archs=all``: install 4-way universal
1562
1563 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1564
1565 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1566
1567 This option should be used in combination with ``--enable-universalsdk=``.
1568
1569 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

1577- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00001578
1579- The PyString functions have been renamed to PyBytes. A batch of
1580 defines were added so that the linker still sees the original
1581 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001619- Issue #1631171: Re-implement the 'warnings' module in C (the
1620 original Python code has been kept as backup). This will allow for
1621 using the 'warning's machinery in such places as the parser where
1622 use of pure Python code is not possible. Both the ``showarning()``
1623 and ``formatwarning()`` gain an optional 'line' argument which is
1624 not called by default for backwards-compatibility reasons. Setting
1625 ``warnings.showwarning()`` to an implementation that lacks support
1626 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001651- The getpass module has been improved on Unix. It now uses /dev/tty
1652 by default and uses stderr instead of stdout. A GetPassWarning is
1653 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001668- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001669 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001689- Issue #2550: The approach used by client/server code for obtaining
1690 ports to listen on in network-oriented tests has been refined in an
1691 effort to facilitate running multiple instances of the entire
1692 regression test suite in parallel without issue.
1693 test_support.bind_port() has been fixed such that it will always
1694 return a unique port -- which wasn't always the case with the
1695 previous implementation, especially if socket options had been set
1696 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1697 new implementation of bind_port() will actually raise an exception
1698 if it is passed an AF_INET/SOCK_STREAM socket with either the
1699 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1700 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1701 the socket it's been passed. This currently only applies to
1702 Windows. This option prevents any other sockets from binding to the
1703 host/port we've bound to, thus removing the possibility of the
1704 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1705 when a second SOCK_STREAM socket binds and accepts to a host/port
1706 that's already been bound by another socket. The optional preferred
1707 port parameter to bind_port() has been removed. Under no
1708 circumstances should tests be hard coding ports!
1709
1710 test_support.find_unused_port() has also been introduced, which will
1711 pass a temporary socket object to bind_port() in order to obtain an
1712 unused port. The temporary socket object is then closed and
1713 deleted, and the port is returned. This method should only be used
1714 for obtaining an unused port in order to pass to an external program
1715 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1716 a parameter to a server-oriented class that doesn't give you direct
1717 access to the underlying socket used.
1718
1719 Finally, test_support.HOST has been introduced, which should be used
1720 for the host argument of any relevant socket calls (i.e. bind and
1721 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001722
1723 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001724 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001725 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1726 test_asynchat and test_socket_ssl.
1727
Georg Brandl3ee81df2008-05-17 18:14:43 +00001728 It is now possible for multiple instances of the regression test
1729 suite to run in parallel without issue.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002005- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002006 issue 215555 for a discussion.
2007
Eric Smitha73fbe72008-02-23 03:09:44 +00002008- Added the future_builtins module, which contains hex() and oct().
2009 These are the PEP 3127 version of these functions, designed to be
2010 compatible with the hex() and oct() builtins from Python 3.0. They
2011 differ slightly in their output formats from the existing, unchanged
2012 Python 2.6 builtins. The expected usage of the future_builtins
2013 module is:
2014 from future_builtins import hex, oct
2015
Eric Smith7ef40bf2008-02-20 23:34:22 +00002016- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2017 exponents for exponents with absolute value < 100. Follows C99
2018 standard. This is a change on Windows, which would use 3 digits.
2019 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2020 so that any alterations it does to the resulting string will be
2021 available in stringlib/formatter.h (for float.__format__).
2022
Eric Smith5a3c1352008-02-19 13:21:56 +00002023- Implemented PEP 3101, Advanced String Formatting. This adds a new
2024 builtin format(); a format() method for str and unicode; a
2025 __format__() method to object, str, unicode, int, long, float, and
2026 datetime; the class string.Formatter; and the C API
2027 PyObject_Format().
2028
Georg Brandl3ee81df2008-05-17 18:14:43 +00002029- Fixed several potential crashes, all caused by specially crafted
2030 __del__ methods exploiting objects in temporarily inconsistent
2031 state.

2042 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002043
Georg Brandl3ee81df2008-05-17 18:14:43 +00002044- Issue #2045: Fix an infinite recursion triggered when printing a
2045 subclass of collections.defaultdict, if its default_factory is set
2046 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002047
Christian Heimesf75dbef2008-02-08 00:11:31 +00002048- Fixed a minor memory leak in dictobject.c. The content of the free
2049 list was not freed on interpreter shutdown.
2050
Georg Brandl3ee81df2008-05-17 18:14:43 +00002051- Limit free list of method and builtin function objects to 256

2055 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002056 to compact the internal free lists of pre-allocted ints and floats.
2057
Georg Brandl3ee81df2008-05-17 18:14:43 +00002058- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2059 calls. Python expected the return type int but the fork familie
2060 returns pi_t.

Christian Heimes4d4f2702008-01-30 11:32:37 +00002070
Georg Brandl3ee81df2008-05-17 18:14:43 +00002071- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2072 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002073
Georg Brandl3ee81df2008-05-17 18:14:43 +00002074- Patch #1473257: generator objects gain a gi_code attribute. This is
2075 the same object as the func_code attribute of the function that
2076 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002077
Georg Brandl3ee81df2008-05-17 18:14:43 +00002078- Issue #1920: "while 0" statements were completely removed by the
2079 compiler, even in the presence of an "else" clause, which is
2080 supposed to be run when the condition is false. Now the compiler
2081 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002082
Guido van Rossumeead05f2008-01-24 18:21:02 +00002083- A few crashers fixed: weakref_in_del.py (issue #1377858);
2084 loosing_dict_ref.py (issue #1303614, test67.py);
2085 borrowed_ref_[34].py (not in tracker).
2086
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002087- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002088 suppressed while an extension is loaded by calling SetErrorMode in
2089 dynload_win.c. The error is still reported properly.
2090
Georg Brandl3ee81df2008-05-17 18:14:43 +00002091- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002092 several extension methods and modules do not work without unicode
2093 support.
2094
Georg Brandl26543b12008-01-21 18:36:51 +00002095- Issue #1882: when compiling code from a string, encoding cookies in the
2096 second line of code were not always recognized correctly.
2097
Georg Brandl14404b62008-01-19 19:27:05 +00002098- Issue #1679: "0x" was taken as a valid integer literal.
2099
Georg Brandl6caad7d2008-01-26 14:19:22 +00002100- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002101 added.
2102
Christian Heimesc94e2b52008-01-14 04:13:37 +00002103- sys.float_info / PyFloat_GetInfo: The floating point information
2104 object was converted from a dict to a specialized structseq object.
2105
Georg Brandl3ee81df2008-05-17 18:14:43 +00002106- Patch #1816: Added sys.flags structseq. It exposes the status of
2107 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002108
Georg Brandl3ee81df2008-05-17 18:14:43 +00002109- Objects/structseq.c: Implemented new structseq representation. The
2110 patch makes structseqs (e.g. the return value of os.stat) more
2111 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002112
Georg Brandl3ee81df2008-05-17 18:14:43 +00002113- Patch #1700288: added a type attribute cache that caches method
2114 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002115
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002116- Bug #1776: __import__() no longer accepts filenames on any platform.
2117 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002118
Georg Brandlaed6c662008-01-07 17:25:53 +00002119- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2120
Georg Brandl3ee81df2008-05-17 18:14:43 +00002121- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2122 envvar and sys.dont_write_bytecode attribute. All these can be set
2123 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002124
Georg Brandl3ee81df2008-05-17 18:14:43 +00002125- Improve some exception messages when Windows fails to load an
2126 extension module. Now we get for example '%1 is not a valid Win32
2127 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002128
Georg Brandl3ee81df2008-05-17 18:14:43 +00002129- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00002130
Georg Brandl3ee81df2008-05-17 18:14:43 +00002131- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2132 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002133
Christian Heimes0a8143f2007-12-18 23:22:54 +00002134- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002135 and INF. float("nan"), float("inf") and float("-inf") now work on
2136 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002137
Georg Brandl3ee81df2008-05-17 18:14:43 +00002138- Compiler now generates simpler and faster code for dictionary
2139 literals. The oparg for BUILD_MAP now indicates an estimated
2140 dictionary size. There is a new opcode, STORE_MAP, for adding
2141 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002142
Georg Brandl3ee81df2008-05-17 18:14:43 +00002143- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00002144
Georg Brandl3ee81df2008-05-17 18:14:43 +00002145- Issue #1620: New property decorator syntax was modifying the
2146 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- Issue #1538: Avoid copying string in split/rsplit if the split char
2149 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002150
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002151- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002152 SystemError.
2153
Nick Coghlanef01d822007-12-03 12:55:17 +00002154- PEP 366: Allow explicit relative imports when executing modules

2156 __package__ attribute.
2157
Georg Brandl3ee81df2008-05-17 18:14:43 +00002158- Issue #1402: Fix a crash on exit, when another thread is still
2159 running, and if the deallocation of its frames somehow calls the
2160 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002161

2163
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00002164- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002165 attribute of an empty cell object.
2166
Georg Brandl3ee81df2008-05-17 18:14:43 +00002167- Issue #1460: The utf-7 incremental decoder did not accept truncated
2168 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002169
Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Patch #1739468: Directories and zipfiles containing a __main__.py
2171 file can now be directly executed by passing their name to the
2172 interpreter. The directory/zipfile is automatically inserted as the
2173 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002174
Georg Brandl3ee81df2008-05-17 18:14:43 +00002175- Issue #1265: Fix a problem with sys.settrace, if the tracing
2176 function uses a generator expression when at the same time the
2177 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002178
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002179- sets and frozensets now have an isdisjoint() method.
2180
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002181- optimize the performance of builtin.sum().
2182
Neal Norwitz44f326e2007-10-05 05:29:17 +00002183- Fix warnings found by the new version of the Coverity checker.
2184
Georg Brandl3ee81df2008-05-17 18:14:43 +00002185- The enumerate() builtin function is no longer bounded to sequences
2186 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2187 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002188
Georg Brandl3ee81df2008-05-17 18:14:43 +00002189- Issue #1686386: Tuple's tp_repr did not take into account the
2190 possibility of having a self-referential tuple, which is possible
2191 from C code. Nor did object's tp_str consider that a type's tp_str
2192 could do something that could lead to an inifinite recursion.
2193 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2194 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002195
Georg Brandl3ee81df2008-05-17 18:14:43 +00002196- Issue #1164: It was possible to trigger deadlock when using the
2197 'print' statement to write to a file since the GIL was not released
2198 as needed. Now PyObject_Print() does the right thing along with
2199 various tp_print implementations of the built-in types and those in
2200 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002201
Georg Brandl3ee81df2008-05-17 18:14:43 +00002202- Issue #1147: Exceptions were directly allowing string exceptions in
2203 their throw() method even though string exceptions no longer
2204 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002205
Georg Brandl3ee81df2008-05-17 18:14:43 +00002206- Issue #1096: Prevent a segfault from getting the repr of a very
2207 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002208
Brett Cannon1e534b52007-09-07 04:18:30 +00002209- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002210 PyObject_Call() never calling back out to Python code to trigger
2211 recursion depth updates/checks. Required the creation of a static
2212 RuntimeError instance in case normalizing an exception put the
2213 recursion check value past its limit. Fixes crashers
2214 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002215
Georg Brandl3ee81df2008-05-17 18:14:43 +00002216- Patch #1031213: Decode source line in SyntaxErrors back to its
2217 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00002218
Georg Brandl7c3b50d2007-07-12 08:38:00 +00002219- Patch #1673759: add a missing overflow check when formatting floats
2220 with %G.
2221
Georg Brandl3ee81df2008-05-17 18:14:43 +00002222- Prevent expandtabs() on string and unicode objects from causing a
2223 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002224

Georg Brandl3ee81df2008-05-17 18:14:43 +00002227- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00002228
Neal Norwitz0ac60192007-05-27 04:08:54 +00002229- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002230 __*__ attributes. (Some already existed, e.g., __doc__ and
2231 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002232
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002233- Add -3 option to the interpreter to warn about features that are
2234 deprecated and will be changed/removed in Python 3.0.
2235
Georg Brandl2134e752007-05-21 20:34:16 +00002236- Patch #1686487: you can now pass any mapping after '**' in function
2237 calls.
2238
Collin Winter62903052007-05-18 23:11:24 +00002239- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002240 "except E as target:". This is to provide forwards compatibility
2241 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002242
Brett Cannon229cee22007-05-05 01:34:02 +00002243- Deprecate BaseException.message as per PEP 352.
2244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002246 inherited from a builtin base.
2247
Vinay Sajip8549ce32007-05-06 17:53:37 +00002248- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002249 setting a plain string, ie don't expand to single letter identifiers.
2250
Raymond Hettinger13936692007-04-11 18:40:58 +00002251- Request #1191699: Slices can now be pickled.
2252
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002253- Request #1193128: str.translate() now allows a None argument for
2254 translations that only remove characters without re-mapping the
2255 remaining characters.
2256
Georg Brandl5cb76c12007-03-21 09:00:39 +00002257- Patch #1682205: a TypeError while unpacking an iterable is no longer
2258 masked by a generic one with the message "unpack non-sequence".
2259
Neal Norwitzaa754b72007-03-21 06:39:48 +00002260- Remove unused file Python/fmod.c.
2261
Guido van Rossum143b5642007-03-23 04:58:42 +00002262- Bug #1683368: The object.__init__() and object.__new__() methods are
2263 now stricter in rejecting excess arguments. The only time when
2264 either allows excess arguments is when it is not overridden and the
2265 other one is. For backwards compatibility, when both are
2266 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002267 warning later). Also, type.__init__() insists on the same signature
2268 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002269
Georg Brandl3ee81df2008-05-17 18:14:43 +00002270- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2271 object to complex using its __complex__() method before falling back
2272 to the __float__() method. Therefore, the functions in the cmath
2273 module now can operate on objects that define a __complex__()
2274 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002275
Georg Brandl3ee81df2008-05-17 18:14:43 +00002276- Patch #1623563: allow __class__ assignment for classes with
2277 __slots__. The old and the new class are still required to have the
2278 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002279
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002283- Patch #1462488: Python no longer segfaults when
2284 ``object.__reduce_ex__()`` is called with an object that is faking
2285 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002286
Georg Brandl3ee81df2008-05-17 18:14:43 +00002287- Patch #1680015: Don't modify __slots__ tuple if it contains an
2288 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00002290- Patch #1444529: the builtin compile() now accepts keyword arguments.
2291
Georg Brandl7b9c5552007-03-12 14:30:05 +00002292- Bug #1678647: write a newline after printing an exception in any
2293 case, even when converting the value to a string failed.
2294
Georg Brandl871f1bc2007-03-12 13:17:36 +00002295- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002296 its argument, if it exists. If not, it will work like before. This
2297 allows customizing the output of dir() in the presence of a
2298 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002299
Collin Winter276887b2007-03-12 16:11:39 +00002300- Patch #922167: Python no longer segfaults when faced with infinitely
2301 self-recursive reload() calls (as reported by bug #742342).
2302
Georg Brandl3ee81df2008-05-17 18:14:43 +00002303- Patch #1675981: remove unreachable code from ``type.__new__()``
2304 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002306- Patch #1491866: change the complex() constructor to allow
2307 parthensized forms. This means complex(repr(x)) now works instead of
2308 raising a ValueError.

2820
Facundo Batistad918a652007-04-24 13:54:38 +00002821- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002822 the client's request was successfully received, understood, and
2823 accepted. Now in these cases no error is raised in urllib (issue
2824 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00002825

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00002832- Added a timeout parameter to the constructor of other protocols
2833 (telnetlib, ftplib, smtplib and poplib). This is second part of the
2834 work started with create_connection() and timeout in httplib, and
2835 closes patch #723312.
2836
Vinay Sajip8549ce32007-05-06 17:53:37 +00002837- Patch #1676823: Added create_connection() to socket.py, which may be
2838 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00002839 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00002840
Martin v. Löwis0af33882007-03-23 13:27:15 +00002841- Bug #978833: Revert r50844, as it broke _socketobject.dup.

2861
Georg Brandlf66b6032007-03-14 08:27:52 +00002862- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863 AttributeError instead of an IOError when the server's response
2864 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002865
Georg Brandl3ee81df2008-05-17 18:14:43 +00002866- Patch #957650: "%var%" environment variable references are now
2867 properly expanded in ntpath.expandvars(), also "~user" home
2868 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00002869
Georg Brandl3ee81df2008-05-17 18:14:43 +00002870- Patch #1429539: pdb now correctly initializes the __main__ module
2871 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002872 correctly now.
2873
Georg Brandlbad6f192007-03-13 21:32:56 +00002874- The nonobvious commands.getstatus() function is now deprecated.

2880
Georg Brandl3ee81df2008-05-17 18:14:43 +00002881- Patch #1530482: add pydoc.render_doc() which returns the
2882 documentation for a thing instead of paging it to stdout, which
2883 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00002884
Georg Brandl3ee81df2008-05-17 18:14:43 +00002885- Patch #1533909: the timeit module now accepts callables in addition

2891 parameter which can be set to False to prevent the default
2892 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00002893
Georg Brandl9e6b4702007-03-13 18:15:41 +00002894- Patch #1581073: add a flag to textwrap that prevents the dropping of
2895 whitespace while wrapping.
2896
Georg Brandl92a6bae2007-03-13 17:43:32 +00002897- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002898 are set for invalid interpolation sequences that would lead to
2899 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00002900

2913
Georg Brandl94fe3f52007-03-13 09:32:11 +00002914- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00002915 field names in its exception message if you try to write a record
2916 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00002934

2942 returned string up to the first NUL character.
2943

2953
Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- unittest now verifies more of its assumptions. In particular,
2955 TestCase and TestSuite subclasses (not instances) are no longer
2956 accepted in TestSuite.addTest(). This should cause no
2957 incompatibility since it never made sense with ordinary subclasses
2958 -- the failure just occurred later, with a more cumbersome
2959 exception.

2968 given a unicode argument and os.listdir() returns unicode filenames.
2969
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003348 time so that opening a database previously created with the DB_DUP
3349 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3350 opens. Specifically: dictionary assignment to a DB object will
3351 replace all values for a given key when the database allows
3352 duplicate values. DB users should use DB.put(k, v) when they want
3353 to store duplicates; not DB[k] = v.

3360 characters with ASCII value less than 32. Also, it correctly quotes
3361 dots only if they occur on a single line, as opposed to the previous
3362 behavior of quoting dots if they are the second character of any
3363 line.
