485What's New in Python 2.6.1
486==========================
487
488*Release date: 04-Dec-2008*
489
490Core and Builtins
491-----------------
492
493- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
494 interpreter to abort ("Fatal Python error: Could not reset the stack!")
495 instead of throwing a MemoryError.
496
497- Issue #4367: Python would segfault during compiling when the unicodedata
498 module couldn't be imported and \N escapes were present.
499
500- Issue #4348: Some bytearray methods returned that didn't cause any change to
501 the bytearray, returned the same bytearray instead of a copy.
502
503- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
504
505- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
506
507- Issue #4048: The parser module now correctly validates relative imports.
508
509- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
510 exec statement.
511
512- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
513 method does not return iterators for the 4th and 5th items.
514
515- Issue #4209: Enabling unicode_literals and the print_function in the same
516 __future__ import didn't work.
517
518- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
519 returned a path longer than MAX_PATH. (But It's doubtful this code path is
520 really executed because I cannot move to such directory on win2k)
521
522- Issue #4069: When set.remove(element) is used with a set element, the element
523 is temporarily replaced with an equivalent frozenset. But the eventual
524 KeyError would always report the empty frozenset([]) as the missing key. Now
525 it correctly refers to the initial element.
526
527- Fixed C99 style comments in several files. Python is now C89 compatible
528 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000675- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
676
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000677- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
678 PyString_FromFormat or PyErr_Format to display size_t values. The macro
679 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
680 ``printf`` function, whereas PyString_FromFormat has an independent
681 implementation and uses "%zd" on all platforms for size_t values.
682 This makes a difference on win64, where ``printf`` needs "%Id" to display
683 64bit values.
684
Benjamin Peterson97179b02008-09-09 20:55:01 +0000685- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
686 error.
687
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000688- Issue #3777: long() applied to a float object now always return a long
689 object; previously an int would be returned for small values. the __long__
690 method is allowed to return either an int or a long, but the behaviour of
691 float objects should not change to respect backward compatibility.
692
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000693- Issue #3751: str.rpartition would perform a left-partition when called with
694 a unicode argument.
695
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000696- Issue #3683: Fix compilation when --without-threads is given.
697
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000698- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000699 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000700 was correctly parsed but parsing of subsequent arguments failed.
701
Vinay Sajip35e3b032008-09-01 14:33:59 +0000702- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000703 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
704 mechanism. In the process, fix a bug where isinstance() and issubclass(),
705 when given a tuple of classes as second argument, were looking up
706 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
707 type object.
708
Neal Norwitz18aa3882008-08-24 05:04:52 +0000709- Fix crashes on memory allocation failure found with failmalloc.
710
711- Fix memory leaks found with valgrind and update suppressions file.
712
713- Fix compiler warnings in opt mode which would lead to invalid memory reads.
714
715- Fix problem using wrong name in decimal module reported by pychecker.
716
Christian Heimes7d4c3172008-08-22 19:47:25 +0000717- Silenced another compiler warning about a used but not defined
718 function 'stringlib_contains_obj'.
719
Benjamin Peterson712ee922008-08-24 18:10:20 +0000720- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
721 ``__delslice__``.
722
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +0000723- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
724 library targets in the Makefile.
725
Gregory P. Smith980b99b2008-09-07 05:15:18 +0000726- Issue #1204: The configure script now tests for additional libraries
727 that may be required when linking against readline. This fixes issues
728 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +0000738- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
739 stack usage in the case of deeply nested objects.
740
Guido van Rossume3c4fd92008-09-10 14:27:00 +0000741- Issue #3629: Fix sre "bytecode" validator for an end case.

744
Nick Coghland2e09382008-09-11 12:11:06 +0000745- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
746 silent misbehaviour when a single instance is nested in multiple
747 with statements, or when the methods are invoked in the wrong order.
748
Vinay Sajip844f7412008-09-09 13:42:08 +0000749- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

775 path to the Python binary.
776
Brett Cannon1eaf0742008-09-02 01:25:16 +0000777- Issue 3602: Moved test.test_support.catch_warning() to
778 warnings.catch_warnings() along with some API cleanup. Expanding the tests
779 for catch_warnings() also led to an improvement in the raising of a
780 DeprecationWarning related to warnings.warn_explicit().
781
Benjamin Peterson973e6c22008-09-01 23:12:58 +0000782- The deprecation warnings for the old camelCase threading API were removed.

800-----------------
801
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000802- Issue #2975: When compiling several extension modules with Visual Studio 2008

813
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000814- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000843What's New in Python 2.6 beta 3?
844================================
845
Barry Warsaw07a4a382008-08-21 01:15:08 +0000846*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000847
848Core and Builtins
849-----------------
850
Guido van Rossumf8402962008-08-20 15:01:50 +0000851- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
852 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
853 extensions do not automatically benefit from the class attribute
854 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
855 to their tp_flags field if they care. This is a backwards
856 compatibility feature; in 3.0, all types will use the cache by
857 default.
858
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000859- Keyword arguments can now follow starred arguments. (``f(a, *args,
860 keyword=23)`` is now valid syntax.)
861
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000862- ctypes function pointers that are COM methods have a boolean True
863 value again.
864
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000865- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
866 by denying s# to parse objects that have a releasebuffer procedure,
867 and introducing s*.
868
Georg Brandl1e13ea92008-08-11 09:07:59 +0000869- Issue #3537: Fix an assertion failure when an empty but presized dict
870 object was stored in the freelist.
871
Mark Dickinsonb6467572008-08-04 21:30:09 +0000872- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
873 ValueError consistently across platforms.
874
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000875- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
876 (64bit Unix, for example), unichr() would truncate its argument and return
877 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
878
Neal Norwitze7d8be82008-07-31 17:17:14 +0000879- Apply security patches from Apple.
880
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000881- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
882 PyErr_ExceptionMatches returns 0 when an exception occurs there.
883
Antoine Pitrou92f82162008-07-25 22:22:08 +0000884- Issue #1819: function calls with several named parameters are now on
885 average 35% faster (as measured by pybench).
886
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000887- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
888 the python debugger steps into a class statement: the free variables (local
889 variables defined in an outer scope) would be deleted from the outer scope.
890
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000891- Issue #2620: Overflow checking when allocating or reallocating memory
892 was not always being done properly in some python types and extension
893 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
894 all been updated to perform better checks and places in the code that
895 would previously leak memory on the error path when such an allocation
896 failed have been fixed.

905
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000906- Issue #2234: distutils failed for some versions of the cygwin compiler. The
907 version reported by these tools does not necessarily follow the python
908 version numbering scheme, so the module is less strict when parsing it.
909
Nick Coghlanf70385a2008-08-18 12:42:46 +0000910- Issue #2235: Added Py3k warnings for types which will become unhashable
911 under the stricter __hash__ inheritance rules in 3.0. Several types
912 which did not meet the rules for hash invariants and were already
913 unhashable in 3.0 have now been explicitly flagged as unhashable in
914 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
915 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
916
Brett Cannon88f801d2008-08-18 00:46:22 +0000917- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

925
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000926- Issue #3575: Incremental decoder's decode function now takes bytearray
927 by using 's*' instead of 't#'.
928
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000929- Issue #2222: Fixed reference leak when occured os.rename()
930 fails unicode conversion on 2nd parameter. (windows only)
931
Facundo Batista94f243a2008-08-17 03:38:39 +0000932- Issue 2464. urllib2 now supports a malformation in the URL received
933 in a redirect.
934
Brett Cannonabe423e2008-08-16 21:47:07 +0000935- Silence the DeprecationWarning raised when importing mimetools in

Brett Cannonabe423e2008-08-16 21:47:07 +0000937
Facundo Batistaeb90b782008-08-16 14:44:07 +0000938- Issue #2776: fixed small issue when handling an URL with double slash
939 after a 302 response in the case of not going through a proxy.
940
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000941- Issue #2676: in the email package, content-type parsing was hanging on
942 pathological input because of quadratic or exponential behaviour of a
943 regular expression.
944
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000945- Issue #3476: binary buffered reading through the new "io" library is now
946 thread-safe.
947
Brett Cannonbf3157b2008-08-14 05:00:03 +0000948- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
949 since mimetools itself is deprecated. Because modules are cached, all
950 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
951
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000952- Issue #3134: shutil referenced undefined WindowsError symbol.

956
Brett Cannon83e81842008-08-09 23:30:55 +0000957- Copied the implementation of reduce() to _functools.reduce() to have a
958 version that did not raise a DeprecationWarning under -3.
959
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000960- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
961 a MemoryError rather than silently stop the iteration.
962
Guido van Rossum59ce9012008-08-09 14:55:34 +0000963- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
964 to _sre.compile() will now be rejected. This should not affect anybody
965 since the re.compile() function never generates invalid re-bytecode.
966
Skip Montanaroa032bf42008-08-08 22:52:51 +0000967- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
968 upon first access it can be automatically initialized from the csv file if
969 it wasn't initialized during instantiation.
970
Brett Cannon3aa2a492008-08-06 22:28:09 +0000971- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
972 the reload() built-in has been removed.
973

Antoine Pitroude781a42008-08-09 12:43:23 +0000986 asking for a specific length. This problem only affected files opened

1043-----------------
1044
Georg Brandl3e483f62008-07-16 22:57:41 +00001045- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1046 its methods now allow for items objects that can be converted to
1047 an integer using operator.index().
1048
Mark Dickinson64b7e502008-07-16 09:40:03 +00001049- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1050 produced a ValueError instead of giving the correct float.
1051
Eric Smitha5fa5a22008-07-16 00:11:49 +00001052- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1053 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1054
Mark Dickinson7103aa42008-07-15 19:08:33 +00001055- Issue #3008: the float type has a new instance method 'float.hex'
1056 and a new class method 'float.fromhex' to convert floating-point
1057 numbers to and from hexadecimal strings, respectively.
1058
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001059- Issue #2235: __hash__ is once again inherited by default. To allow
1060 collections.Hashable to remain meaningful in the presence of the
1061 default hash implementation (object.__hash__), it is now possible
1062 to explicit block inheritance of hash by setting __hash__=None at
1063 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1064 level.
1065
Nick Coghlanb028f502008-07-13 14:52:36 +00001066- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1067 the parent module cannot be found while performing an absolute import.
1068 This means that an incorrectly defined __package__ attribute will
1069 now only prevent relative imports in that module rather than causing
1070 all imports from that module to fail.
1071
Nick Coghlan14ff9942008-07-08 14:21:42 +00001072- Issue #2517: Allow unicode messages in Exceptions again by correctly

1082 another thread's dictionary.
1083
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001084- Issue #3004: Minor change to slice.indices(): the start and stop
1085 arguments are now treated identically, making the behaviour easier
1086 to describe and understand. For example, slice(None, -10,
1087 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1088 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1089 10, -1).
1090
Georg Brandl278fc502008-07-19 12:46:12 +00001091- Issue #3219: Calling a function with repeated keyword arguments,
1092 f(a=2, a=23), would not cause a syntax error. This was a regression
1093 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00001095- Issue #2862: Make int and float freelist management consistent with
1096 other freelists. Changes their CompactFreeList apis into

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001131- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1132 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001133 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001134 content-length. The problem had been corrected in the 2.4 branch, but never
1135 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001150- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00001541- On MacOS X it is now possible to install the framework in 64-bit
1542 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001543 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001544
1545 This is controlled by the configure argument ``--with-universal-archs``:
1546
1547 - ``--with-universal-archs=all``: install 4-way universal
1548
1549 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1550
1551 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1552
1553 This option should be used in combination with ``--enable-universalsdk=``.
1554
1555 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

1560
Georg Brandl74a1dea2008-05-28 11:21:39 +00001561- Add ``PyType_Modified()`` as a public API to clear the type cache.
1562
1563- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00001564
1565- The PyString functions have been renamed to PyBytes. A batch of
1566 defines were added so that the linker still sees the original
1567 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001605- Issue #1631171: Re-implement the 'warnings' module in C (the
1606 original Python code has been kept as backup). This will allow for
1607 using the 'warning's machinery in such places as the parser where
1608 use of pure Python code is not possible. Both the ``showarning()``
1609 and ``formatwarning()`` gain an optional 'line' argument which is
1610 not called by default for backwards-compatibility reasons. Setting
1611 ``warnings.showwarning()`` to an implementation that lacks support
1612 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001637- The getpass module has been improved on Unix. It now uses /dev/tty
1638 by default and uses stderr instead of stdout. A GetPassWarning is
1639 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001654- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001655 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001675- Issue #2550: The approach used by client/server code for obtaining
1676 ports to listen on in network-oriented tests has been refined in an
1677 effort to facilitate running multiple instances of the entire
1678 regression test suite in parallel without issue.
1679 test_support.bind_port() has been fixed such that it will always
1680 return a unique port -- which wasn't always the case with the
1681 previous implementation, especially if socket options had been set
1682 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1683 new implementation of bind_port() will actually raise an exception
1684 if it is passed an AF_INET/SOCK_STREAM socket with either the
1685 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1686 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1687 the socket it's been passed. This currently only applies to
1688 Windows. This option prevents any other sockets from binding to the
1689 host/port we've bound to, thus removing the possibility of the
1690 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1691 when a second SOCK_STREAM socket binds and accepts to a host/port
1692 that's already been bound by another socket. The optional preferred
1693 port parameter to bind_port() has been removed. Under no
1694 circumstances should tests be hard coding ports!
1695
1696 test_support.find_unused_port() has also been introduced, which will
1697 pass a temporary socket object to bind_port() in order to obtain an
1698 unused port. The temporary socket object is then closed and
1699 deleted, and the port is returned. This method should only be used
1700 for obtaining an unused port in order to pass to an external program
1701 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1702 a parameter to a server-oriented class that doesn't give you direct
1703 access to the underlying socket used.
1704
1705 Finally, test_support.HOST has been introduced, which should be used
1706 for the host argument of any relevant socket calls (i.e. bind and
1707 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001708
1709 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001710 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001711 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1712 test_asynchat and test_socket_ssl.
1713
Georg Brandl3ee81df2008-05-17 18:14:43 +00001714 It is now possible for multiple instances of the regression test
1715 suite to run in parallel without issue.

1983
Fred Drakea8ee94b2008-03-01 02:45:07 +00001984- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001985 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00001991- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001992 issue 215555 for a discussion.
1993
Eric Smitha73fbe72008-02-23 03:09:44 +00001994- Added the future_builtins module, which contains hex() and oct().
1995 These are the PEP 3127 version of these functions, designed to be
1996 compatible with the hex() and oct() builtins from Python 3.0. They
1997 differ slightly in their output formats from the existing, unchanged
1998 Python 2.6 builtins. The expected usage of the future_builtins
1999 module is:
2000 from future_builtins import hex, oct
2001
Eric Smith7ef40bf2008-02-20 23:34:22 +00002002- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2003 exponents for exponents with absolute value < 100. Follows C99
2004 standard. This is a change on Windows, which would use 3 digits.
2005 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2006 so that any alterations it does to the resulting string will be
2007 available in stringlib/formatter.h (for float.__format__).
2008
Eric Smith5a3c1352008-02-19 13:21:56 +00002009- Implemented PEP 3101, Advanced String Formatting. This adds a new
2010 builtin format(); a format() method for str and unicode; a
2011 __format__() method to object, str, unicode, int, long, float, and
2012 datetime; the class string.Formatter; and the C API
2013 PyObject_Format().
2014
Georg Brandl3ee81df2008-05-17 18:14:43 +00002015- Fixed several potential crashes, all caused by specially crafted
2016 __del__ methods exploiting objects in temporarily inconsistent
2017 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002018
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002019- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002020 prevent a possible crash: an Abstract Base Class would try to access
2021 a slot on a registered virtual subclass.

2028 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002029
Georg Brandl3ee81df2008-05-17 18:14:43 +00002030- Issue #2045: Fix an infinite recursion triggered when printing a
2031 subclass of collections.defaultdict, if its default_factory is set
2032 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002033
Christian Heimesf75dbef2008-02-08 00:11:31 +00002034- Fixed a minor memory leak in dictobject.c. The content of the free
2035 list was not freed on interpreter shutdown.
2036
Georg Brandl3ee81df2008-05-17 18:14:43 +00002037- Limit free list of method and builtin function objects to 256
2038 entries each.

2041 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002042 to compact the internal free lists of pre-allocted ints and floats.
2043
Georg Brandl3ee81df2008-05-17 18:14:43 +00002044- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2045 calls. Python expected the return type int but the fork familie
2046 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002047
Georg Brandl3ee81df2008-05-17 18:14:43 +00002048- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002060- Patch #1473257: generator objects gain a gi_code attribute. This is
2061 the same object as the func_code attribute of the function that
2062 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002063
Georg Brandl3ee81df2008-05-17 18:14:43 +00002064- Issue #1920: "while 0" statements were completely removed by the
2065 compiler, even in the presence of an "else" clause, which is
2066 supposed to be run when the condition is false. Now the compiler
2067 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002068
Guido van Rossumeead05f2008-01-24 18:21:02 +00002069- A few crashers fixed: weakref_in_del.py (issue #1377858);
2070 loosing_dict_ref.py (issue #1303614, test67.py);
2071 borrowed_ref_[34].py (not in tracker).
2072
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002073- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002074 suppressed while an extension is loaded by calling SetErrorMode in
2075 dynload_win.c. The error is still reported properly.
2076
Georg Brandl3ee81df2008-05-17 18:14:43 +00002077- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002078 several extension methods and modules do not work without unicode
2079 support.
2080
Georg Brandl26543b12008-01-21 18:36:51 +00002081- Issue #1882: when compiling code from a string, encoding cookies in the
2082 second line of code were not always recognized correctly.
2083
Georg Brandl14404b62008-01-19 19:27:05 +00002084- Issue #1679: "0x" was taken as a valid integer literal.
2085
Georg Brandl6caad7d2008-01-26 14:19:22 +00002086- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002087 added.
2088
Christian Heimesc94e2b52008-01-14 04:13:37 +00002089- sys.float_info / PyFloat_GetInfo: The floating point information
2090 object was converted from a dict to a specialized structseq object.
2091
Georg Brandl3ee81df2008-05-17 18:14:43 +00002092- Patch #1816: Added sys.flags structseq. It exposes the status of
2093 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002094
Georg Brandl3ee81df2008-05-17 18:14:43 +00002095- Objects/structseq.c: Implemented new structseq representation. The
2096 patch makes structseqs (e.g. the return value of os.stat) more
2097 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002098
Georg Brandl3ee81df2008-05-17 18:14:43 +00002099- Patch #1700288: added a type attribute cache that caches method
2100 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002101
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002102- Bug #1776: __import__() no longer accepts filenames on any platform.
2103 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002104
Georg Brandlaed6c662008-01-07 17:25:53 +00002105- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2106
Georg Brandl3ee81df2008-05-17 18:14:43 +00002107- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2108 envvar and sys.dont_write_bytecode attribute. All these can be set
2109 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002110
Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Improve some exception messages when Windows fails to load an
2112 extension module. Now we get for example '%1 is not a valid Win32
2113 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002114
Georg Brandl3ee81df2008-05-17 18:14:43 +00002115- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002117- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2118 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002119
Christian Heimes0a8143f2007-12-18 23:22:54 +00002120- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002121 and INF. float("nan"), float("inf") and float("-inf") now work on
2122 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002123
Georg Brandl3ee81df2008-05-17 18:14:43 +00002124- Compiler now generates simpler and faster code for dictionary
2125 literals. The oparg for BUILD_MAP now indicates an estimated
2126 dictionary size. There is a new opcode, STORE_MAP, for adding
2127 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002128
Georg Brandl3ee81df2008-05-17 18:14:43 +00002129- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002134- Issue #1538: Avoid copying string in split/rsplit if the split char
2135 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002136
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002137- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002138 SystemError.
2139
Nick Coghlanef01d822007-12-03 12:55:17 +00002140- PEP 366: Allow explicit relative imports when executing modules

2145 running, and if the deallocation of its frames somehow calls the
2146 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002147

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002151 attribute of an empty cell object.
2152
Georg Brandl3ee81df2008-05-17 18:14:43 +00002153- Issue #1460: The utf-7 incremental decoder did not accept truncated
2154 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002155
Georg Brandl3ee81df2008-05-17 18:14:43 +00002156- Patch #1739468: Directories and zipfiles containing a __main__.py
2157 file can now be directly executed by passing their name to the
2158 interpreter. The directory/zipfile is automatically inserted as the
2159 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002160
Georg Brandl3ee81df2008-05-17 18:14:43 +00002161- Issue #1265: Fix a problem with sys.settrace, if the tracing
2162 function uses a generator expression when at the same time the
2163 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002164
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002165- sets and frozensets now have an isdisjoint() method.
2166
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002167- optimize the performance of builtin.sum().
2168
Neal Norwitz44f326e2007-10-05 05:29:17 +00002169- Fix warnings found by the new version of the Coverity checker.
2170
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171- The enumerate() builtin function is no longer bounded to sequences
2172 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2173 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002174
Georg Brandl3ee81df2008-05-17 18:14:43 +00002175- Issue #1686386: Tuple's tp_repr did not take into account the
2176 possibility of having a self-referential tuple, which is possible
2177 from C code. Nor did object's tp_str consider that a type's tp_str
2178 could do something that could lead to an inifinite recursion.
2179 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2180 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Issue #1164: It was possible to trigger deadlock when using the
2183 'print' statement to write to a file since the GIL was not released
2184 as needed. Now PyObject_Print() does the right thing along with
2185 various tp_print implementations of the built-in types and those in
2186 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002187
Georg Brandl3ee81df2008-05-17 18:14:43 +00002188- Issue #1147: Exceptions were directly allowing string exceptions in
2189 their throw() method even though string exceptions no longer
2190 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002191
Georg Brandl3ee81df2008-05-17 18:14:43 +00002192- Issue #1096: Prevent a segfault from getting the repr of a very
2193 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002194
Brett Cannon1e534b52007-09-07 04:18:30 +00002195- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002196 PyObject_Call() never calling back out to Python code to trigger
2197 recursion depth updates/checks. Required the creation of a static
2198 RuntimeError instance in case normalizing an exception put the
2199 recursion check value past its limit. Fixes crashers
2200 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002201
Georg Brandl3ee81df2008-05-17 18:14:43 +00002202- Patch #1031213: Decode source line in SyntaxErrors back to its

2206 with %G.
2207
Georg Brandl3ee81df2008-05-17 18:14:43 +00002208- Prevent expandtabs() on string and unicode objects from causing a
2209 segfault when a large width is passed on 32-bit platforms.

Georg Brandla5ea6892007-06-01 11:33:33 +00002214
Neal Norwitz0ac60192007-05-27 04:08:54 +00002215- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002216 __*__ attributes. (Some already existed, e.g., __doc__ and
2217 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002218
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002219- Add -3 option to the interpreter to warn about features that are
2220 deprecated and will be changed/removed in Python 3.0.
2221
Georg Brandl2134e752007-05-21 20:34:16 +00002222- Patch #1686487: you can now pass any mapping after '**' in function
2223 calls.
2224
Collin Winter62903052007-05-18 23:11:24 +00002225- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002226 "except E as target:". This is to provide forwards compatibility
2227 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002228
Brett Cannon229cee22007-05-05 01:34:02 +00002229- Deprecate BaseException.message as per PEP 352.
2230
Georg Brandl3ee81df2008-05-17 18:14:43 +00002231- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002232 inherited from a builtin base.
2233
Vinay Sajip8549ce32007-05-06 17:53:37 +00002234- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002235 setting a plain string, ie don't expand to single letter identifiers.
2236
Raymond Hettinger13936692007-04-11 18:40:58 +00002237- Request #1191699: Slices can now be pickled.
2238
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002239- Request #1193128: str.translate() now allows a None argument for
2240 translations that only remove characters without re-mapping the
2241 remaining characters.
2242
Georg Brandl5cb76c12007-03-21 09:00:39 +00002243- Patch #1682205: a TypeError while unpacking an iterable is no longer
2244 masked by a generic one with the message "unpack non-sequence".
2245
Neal Norwitzaa754b72007-03-21 06:39:48 +00002246- Remove unused file Python/fmod.c.
2247
Guido van Rossum143b5642007-03-23 04:58:42 +00002248- Bug #1683368: The object.__init__() and object.__new__() methods are
2249 now stricter in rejecting excess arguments. The only time when
2250 either allows excess arguments is when it is not overridden and the
2251 other one is. For backwards compatibility, when both are
2252 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002253 warning later). Also, type.__init__() insists on the same signature
2254 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002255
Georg Brandl3ee81df2008-05-17 18:14:43 +00002256- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2257 object to complex using its __complex__() method before falling back
2258 to the __float__() method. Therefore, the functions in the cmath
2259 module now can operate on objects that define a __complex__()
2260 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002261
Georg Brandl3ee81df2008-05-17 18:14:43 +00002262- Patch #1623563: allow __class__ assignment for classes with
2263 __slots__. The old and the new class are still required to have the
2264 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002265
Georg Brandl3ee81df2008-05-17 18:14:43 +00002266- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002269- Patch #1462488: Python no longer segfaults when
2270 ``object.__reduce_ex__()`` is called with an object that is faking
2271 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002272
Georg Brandl3ee81df2008-05-17 18:14:43 +00002273- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002276- Patch #1444529: the builtin compile() now accepts keyword arguments.
2277
Georg Brandl7b9c5552007-03-12 14:30:05 +00002278- Bug #1678647: write a newline after printing an exception in any
2279 case, even when converting the value to a string failed.
2280
Georg Brandl871f1bc2007-03-12 13:17:36 +00002281- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002282 its argument, if it exists. If not, it will work like before. This
2283 allows customizing the output of dir() in the presence of a
2284 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002285
Collin Winter276887b2007-03-12 16:11:39 +00002286- Patch #922167: Python no longer segfaults when faced with infinitely
2287 self-recursive reload() calls (as reported by bug #742342).
2288
Georg Brandl3ee81df2008-05-17 18:14:43 +00002289- Patch #1675981: remove unreachable code from ``type.__new__()``
2290 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002292- Patch #1491866: change the complex() constructor to allow
2293 parthensized forms. This means complex(repr(x)) now works instead of
2294 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002295
Georg Brandlaa2321b2007-03-07 00:40:28 +00002296- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002297 makes the filenames the warning module prints much more sensible
2298 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002299

2805 ".cpp" too.
2806
Facundo Batistad918a652007-04-24 13:54:38 +00002807- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808 the client's request was successfully received, understood, and
2809 accepted. Now in these cases no error is raised in urllib (issue
2810 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00002811

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00002818- Added a timeout parameter to the constructor of other protocols
2819 (telnetlib, ftplib, smtplib and poplib). This is second part of the
2820 work started with create_connection() and timeout in httplib, and
2821 closes patch #723312.
2822
Vinay Sajip8549ce32007-05-06 17:53:37 +00002823- Patch #1676823: Added create_connection() to socket.py, which may be
2824 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00002825 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00002826
Martin v. Löwis0af33882007-03-23 13:27:15 +00002827- Bug #978833: Revert r50844, as it broke _socketobject.dup.

2847
Georg Brandlf66b6032007-03-14 08:27:52 +00002848- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849 AttributeError instead of an IOError when the server's response
2850 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002851
Georg Brandl3ee81df2008-05-17 18:14:43 +00002852- Patch #957650: "%var%" environment variable references are now
2853 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00002855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Patch #1429539: pdb now correctly initializes the __main__ module
2857 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002858 correctly now.
2859
Georg Brandlbad6f192007-03-13 21:32:56 +00002860- The nonobvious commands.getstatus() function is now deprecated.

2866
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Patch #1530482: add pydoc.render_doc() which returns the
2868 documentation for a thing instead of paging it to stdout, which
2869 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00002870
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871- Patch #1533909: the timeit module now accepts callables in addition

2877 parameter which can be set to False to prevent the default
2878 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00002879
Georg Brandl9e6b4702007-03-13 18:15:41 +00002880- Patch #1581073: add a flag to textwrap that prevents the dropping of
2881 whitespace while wrapping.
2882
Georg Brandl92a6bae2007-03-13 17:43:32 +00002883- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884 are set for invalid interpolation sequences that would lead to
2885 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00002886

Georg Brandl3ee81df2008-05-17 18:14:43 +00002901 field names in its exception message if you try to write a record
2902 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00002920

2928 returned string up to the first NUL character.
2929

2939
Georg Brandl3ee81df2008-05-17 18:14:43 +00002940- unittest now verifies more of its assumptions. In particular,
2941 TestCase and TestSuite subclasses (not instances) are no longer
2942 accepted in TestSuite.addTest(). This should cause no
2943 incompatibility since it never made sense with ordinary subclasses
2944 -- the failure just occurred later, with a more cumbersome
2945 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00002946

2954 given a unicode argument and os.listdir() returns unicode filenames.
2955
Georg Brandl3ee81df2008-05-17 18:14:43 +00002956- Patch #1673619: setup.py identifies extension modules it doesn't
2957 know how to build and those it knows how to build but that fail to
2958 build.

3316 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3317 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003334 time so that opening a database previously created with the DB_DUP
3335 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3336 opens. Specifically: dictionary assignment to a DB object will
3337 replace all values for a given key when the database allows
3338 duplicate values. DB users should use DB.put(k, v) when they want
3339 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003340

3346 characters with ASCII value less than 32. Also, it correctly quotes
3347 dots only if they occur on a single line, as opposed to the previous
3348 behavior of quoting dots if they are the second character of any
3349 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003350
