483What's New in Python 2.6.1
484==========================
485
486*Release date: 04-Dec-2008*
487
488Core and Builtins
489-----------------
490
491- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
492 interpreter to abort ("Fatal Python error: Could not reset the stack!")
493 instead of throwing a MemoryError.
494
495- Issue #4367: Python would segfault during compiling when the unicodedata
496 module couldn't be imported and \N escapes were present.
497
498- Issue #4348: Some bytearray methods returned that didn't cause any change to
499 the bytearray, returned the same bytearray instead of a copy.
500
501- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
502
503- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
504
505- Issue #4048: The parser module now correctly validates relative imports.
506
507- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

511 method does not return iterators for the 4th and 5th items.
512
513- Issue #4209: Enabling unicode_literals and the print_function in the same
514 __future__ import didn't work.
515
516- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
517 returned a path longer than MAX_PATH. (But It's doubtful this code path is
518 really executed because I cannot move to such directory on win2k)
519
520- Issue #4069: When set.remove(element) is used with a set element, the element
521 is temporarily replaced with an equivalent frozenset. But the eventual
522 KeyError would always report the empty frozenset([]) as the missing key. Now
523 it correctly refers to the initial element.
524
525- Fixed C99 style comments in several files. Python is now C89 compatible
526 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000675- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
676 PyString_FromFormat or PyErr_Format to display size_t values. The macro
677 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
678 ``printf`` function, whereas PyString_FromFormat has an independent
679 implementation and uses "%zd" on all platforms for size_t values.
680 This makes a difference on win64, where ``printf`` needs "%Id" to display
681 64bit values.
682
Benjamin Peterson97179b02008-09-09 20:55:01 +0000683- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
684 error.
685
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000686- Issue #3777: long() applied to a float object now always return a long
687 object; previously an int would be returned for small values. the __long__
688 method is allowed to return either an int or a long, but the behaviour of
689 float objects should not change to respect backward compatibility.
690
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000691- Issue #3751: str.rpartition would perform a left-partition when called with
692 a unicode argument.
693

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000696- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000697 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000698 was correctly parsed but parsing of subsequent arguments failed.
699
Vinay Sajip35e3b032008-09-01 14:33:59 +0000700- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000701 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
702 mechanism. In the process, fix a bug where isinstance() and issubclass(),
703 when given a tuple of classes as second argument, were looking up
704 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
705 type object.
706
Neal Norwitz18aa3882008-08-24 05:04:52 +0000707- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +0000715- Silenced another compiler warning about a used but not defined
716 function 'stringlib_contains_obj'.
717
Benjamin Peterson712ee922008-08-24 18:10:20 +0000718- Added warnings on the use of ``__getslice__``, ``__setslice__``, or

776 warnings.catch_warnings() along with some API cleanup. Expanding the tests
777 for catch_warnings() also led to an improvement in the raising of a
778 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000841What's New in Python 2.6 beta 3?
842================================
843
Barry Warsaw07a4a382008-08-21 01:15:08 +0000844*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000845
846Core and Builtins
847-----------------
848
Guido van Rossumf8402962008-08-20 15:01:50 +0000849- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
850 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
851 extensions do not automatically benefit from the class attribute
852 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
853 to their tp_flags field if they care. This is a backwards
854 compatibility feature; in 3.0, all types will use the cache by
855 default.
856
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000857- Keyword arguments can now follow starred arguments. (``f(a, *args,
858 keyword=23)`` is now valid syntax.)
859
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000860- ctypes function pointers that are COM methods have a boolean True
861 value again.
862
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000863- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
864 by denying s# to parse objects that have a releasebuffer procedure,
865 and introducing s*.
866
Georg Brandl1e13ea92008-08-11 09:07:59 +0000867- Issue #3537: Fix an assertion failure when an empty but presized dict
868 object was stored in the freelist.
869
Mark Dickinsonb6467572008-08-04 21:30:09 +0000870- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
871 ValueError consistently across platforms.
872
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000873- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
874 (64bit Unix, for example), unichr() would truncate its argument and return
875 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
876
Neal Norwitze7d8be82008-07-31 17:17:14 +0000877- Apply security patches from Apple.
878
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000879- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
880 PyErr_ExceptionMatches returns 0 when an exception occurs there.
881
Antoine Pitrou92f82162008-07-25 22:22:08 +0000882- Issue #1819: function calls with several named parameters are now on
883 average 35% faster (as measured by pybench).
884
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000885- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
886 the python debugger steps into a class statement: the free variables (local
887 variables defined in an outer scope) would be deleted from the outer scope.
888
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000889- Issue #2620: Overflow checking when allocating or reallocating memory
890 was not always being done properly in some python types and extension
891 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
892 all been updated to perform better checks and places in the code that
893 would previously leak memory on the error path when such an allocation
894 failed have been fixed.

903
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000904- Issue #2234: distutils failed for some versions of the cygwin compiler. The
905 version reported by these tools does not necessarily follow the python
906 version numbering scheme, so the module is less strict when parsing it.
907
Nick Coghlanf70385a2008-08-18 12:42:46 +0000908- Issue #2235: Added Py3k warnings for types which will become unhashable
909 under the stricter __hash__ inheritance rules in 3.0. Several types
910 which did not meet the rules for hash invariants and were already
911 unhashable in 3.0 have now been explicitly flagged as unhashable in
912 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
913 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
914
Brett Cannon88f801d2008-08-18 00:46:22 +0000915- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

923
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000924- Issue #3575: Incremental decoder's decode function now takes bytearray
925 by using 's*' instead of 't#'.
926
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000927- Issue #2222: Fixed reference leak when occured os.rename()
928 fails unicode conversion on 2nd parameter. (windows only)
929
Facundo Batista94f243a2008-08-17 03:38:39 +0000930- Issue 2464. urllib2 now supports a malformation in the URL received
931 in a redirect.
932
Brett Cannonabe423e2008-08-16 21:47:07 +0000933- Silence the DeprecationWarning raised when importing mimetools in

Brett Cannonabe423e2008-08-16 21:47:07 +0000935
Facundo Batistaeb90b782008-08-16 14:44:07 +0000936- Issue #2776: fixed small issue when handling an URL with double slash
937 after a 302 response in the case of not going through a proxy.
938
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000939- Issue #2676: in the email package, content-type parsing was hanging on
940 pathological input because of quadratic or exponential behaviour of a
941 regular expression.
942
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000943- Issue #3476: binary buffered reading through the new "io" library is now
944 thread-safe.
945
Brett Cannonbf3157b2008-08-14 05:00:03 +0000946- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
947 since mimetools itself is deprecated. Because modules are cached, all
948 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
949
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000950- Issue #3134: shutil referenced undefined WindowsError symbol.
951
Robert Schuppenies14646332008-08-10 11:01:53 +0000952- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
953 menu entries were not deleted.
954
Brett Cannon83e81842008-08-09 23:30:55 +0000955- Copied the implementation of reduce() to _functools.reduce() to have a
956 version that did not raise a DeprecationWarning under -3.
957
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000958- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
959 a MemoryError rather than silently stop the iteration.
960
Guido van Rossum59ce9012008-08-09 14:55:34 +0000961- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
962 to _sre.compile() will now be rejected. This should not affect anybody
963 since the re.compile() function never generates invalid re-bytecode.
964
Skip Montanaroa032bf42008-08-08 22:52:51 +0000965- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
966 upon first access it can be automatically initialized from the csv file if
967 it wasn't initialized during instantiation.
968
Brett Cannon3aa2a492008-08-06 22:28:09 +0000969- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
970 the reload() built-in has been removed.
971

Antoine Pitroude781a42008-08-09 12:43:23 +0000984 asking for a specific length. This problem only affected files opened

1041-----------------
1042
Georg Brandl3e483f62008-07-16 22:57:41 +00001043- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1044 its methods now allow for items objects that can be converted to
1045 an integer using operator.index().
1046
Mark Dickinson64b7e502008-07-16 09:40:03 +00001047- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1048 produced a ValueError instead of giving the correct float.
1049
Eric Smitha5fa5a22008-07-16 00:11:49 +00001050- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1051 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1052
Mark Dickinson7103aa42008-07-15 19:08:33 +00001053- Issue #3008: the float type has a new instance method 'float.hex'
1054 and a new class method 'float.fromhex' to convert floating-point
1055 numbers to and from hexadecimal strings, respectively.
1056
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001057- Issue #2235: __hash__ is once again inherited by default. To allow
1058 collections.Hashable to remain meaningful in the presence of the
1059 default hash implementation (object.__hash__), it is now possible
1060 to explicit block inheritance of hash by setting __hash__=None at
1061 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1062 level.
1063
Nick Coghlanb028f502008-07-13 14:52:36 +00001064- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1065 the parent module cannot be found while performing an absolute import.
1066 This means that an incorrectly defined __package__ attribute will
1067 now only prevent relative imports in that module rather than causing
1068 all imports from that module to fail.
1069
Nick Coghlan14ff9942008-07-08 14:21:42 +00001070- Issue #2517: Allow unicode messages in Exceptions again by correctly

1080 another thread's dictionary.
1081
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001082- Issue #3004: Minor change to slice.indices(): the start and stop
1083 arguments are now treated identically, making the behaviour easier
1084 to describe and understand. For example, slice(None, -10,
1085 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1086 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1087 10, -1).
1088
Georg Brandl278fc502008-07-19 12:46:12 +00001089- Issue #3219: Calling a function with repeated keyword arguments,
1090 f(a=2, a=23), would not cause a syntax error. This was a regression
1091 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00001093- Issue #2862: Make int and float freelist management consistent with
1094 other freelists. Changes their CompactFreeList apis into

1102 error when they failed.
1103
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001104- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001129- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1130 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001131 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001132 content-length. The problem had been corrected in the 2.4 branch, but never
1133 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001148- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00001541 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001542
1543 This is controlled by the configure argument ``--with-universal-archs``:
1544
1545 - ``--with-universal-archs=all``: install 4-way universal
1546
1547 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1548
1549 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1550
1551 This option should be used in combination with ``--enable-universalsdk=``.
1552
1553 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

1558
Georg Brandl74a1dea2008-05-28 11:21:39 +00001559- Add ``PyType_Modified()`` as a public API to clear the type cache.
1560
1561- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00001562
1563- The PyString functions have been renamed to PyBytes. A batch of
1564 defines were added so that the linker still sees the original
1565 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001603- Issue #1631171: Re-implement the 'warnings' module in C (the
1604 original Python code has been kept as backup). This will allow for
1605 using the 'warning's machinery in such places as the parser where
1606 use of pure Python code is not possible. Both the ``showarning()``
1607 and ``formatwarning()`` gain an optional 'line' argument which is
1608 not called by default for backwards-compatibility reasons. Setting
1609 ``warnings.showwarning()`` to an implementation that lacks support
1610 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001652- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001653 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001673- Issue #2550: The approach used by client/server code for obtaining
1674 ports to listen on in network-oriented tests has been refined in an
1675 effort to facilitate running multiple instances of the entire
1676 regression test suite in parallel without issue.
1677 test_support.bind_port() has been fixed such that it will always
1678 return a unique port -- which wasn't always the case with the
1679 previous implementation, especially if socket options had been set
1680 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1681 new implementation of bind_port() will actually raise an exception
1682 if it is passed an AF_INET/SOCK_STREAM socket with either the
1683 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1684 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1685 the socket it's been passed. This currently only applies to
1686 Windows. This option prevents any other sockets from binding to the
1687 host/port we've bound to, thus removing the possibility of the
1688 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1689 when a second SOCK_STREAM socket binds and accepts to a host/port
1690 that's already been bound by another socket. The optional preferred
1691 port parameter to bind_port() has been removed. Under no
1692 circumstances should tests be hard coding ports!
1693
1694 test_support.find_unused_port() has also been introduced, which will
1695 pass a temporary socket object to bind_port() in order to obtain an
1696 unused port. The temporary socket object is then closed and
1697 deleted, and the port is returned. This method should only be used
1698 for obtaining an unused port in order to pass to an external program
1699 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1700 a parameter to a server-oriented class that doesn't give you direct
1701 access to the underlying socket used.
1702
1703 Finally, test_support.HOST has been introduced, which should be used
1704 for the host argument of any relevant socket calls (i.e. bind and
1705 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001706
1707 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001708 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001709 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1710 test_asynchat and test_socket_ssl.
1711
Georg Brandl3ee81df2008-05-17 18:14:43 +00001712 It is now possible for multiple instances of the regression test
1713 suite to run in parallel without issue.

1981
Fred Drakea8ee94b2008-03-01 02:45:07 +00001982- Issue #2051: pyc and pyo files are no longer created with permission

Vinay Sajipb7edfc42008-04-02 21:10:23 +00001989- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001990 issue 215555 for a discussion.
1991
Eric Smitha73fbe72008-02-23 03:09:44 +00001992- Added the future_builtins module, which contains hex() and oct().
1993 These are the PEP 3127 version of these functions, designed to be
1994 compatible with the hex() and oct() builtins from Python 3.0. They
1995 differ slightly in their output formats from the existing, unchanged
1996 Python 2.6 builtins. The expected usage of the future_builtins
1997 module is:
1998 from future_builtins import hex, oct
1999
Eric Smith7ef40bf2008-02-20 23:34:22 +00002000- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2001 exponents for exponents with absolute value < 100. Follows C99
2002 standard. This is a change on Windows, which would use 3 digits.
2003 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2004 so that any alterations it does to the resulting string will be
2005 available in stringlib/formatter.h (for float.__format__).
2006
Eric Smith5a3c1352008-02-19 13:21:56 +00002007- Implemented PEP 3101, Advanced String Formatting. This adds a new
2008 builtin format(); a format() method for str and unicode; a
2009 __format__() method to object, str, unicode, int, long, float, and
2010 datetime; the class string.Formatter; and the C API
2011 PyObject_Format().
2012
Georg Brandl3ee81df2008-05-17 18:14:43 +00002013- Fixed several potential crashes, all caused by specially crafted
2014 __del__ methods exploiting objects in temporarily inconsistent
2015 state.

2026 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002027
Georg Brandl3ee81df2008-05-17 18:14:43 +00002028- Issue #2045: Fix an infinite recursion triggered when printing a
2029 subclass of collections.defaultdict, if its default_factory is set
2030 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002031
Christian Heimesf75dbef2008-02-08 00:11:31 +00002032- Fixed a minor memory leak in dictobject.c. The content of the free
2033 list was not freed on interpreter shutdown.
2034
Georg Brandl3ee81df2008-05-17 18:14:43 +00002035- Limit free list of method and builtin function objects to 256

2039 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002040 to compact the internal free lists of pre-allocted ints and floats.
2041
Georg Brandl3ee81df2008-05-17 18:14:43 +00002042- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2043 calls. Python expected the return type int but the fork familie
2044 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002045

Georg Brandl3ee81df2008-05-17 18:14:43 +00002062- Issue #1920: "while 0" statements were completely removed by the
2063 compiler, even in the presence of an "else" clause, which is
2064 supposed to be run when the condition is false. Now the compiler
2065 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00002067- A few crashers fixed: weakref_in_del.py (issue #1377858);
2068 loosing_dict_ref.py (issue #1303614, test67.py);
2069 borrowed_ref_[34].py (not in tracker).
2070
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002071- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002072 suppressed while an extension is loaded by calling SetErrorMode in
2073 dynload_win.c. The error is still reported properly.
2074
Georg Brandl3ee81df2008-05-17 18:14:43 +00002075- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002076 several extension methods and modules do not work without unicode
2077 support.
2078
Georg Brandl26543b12008-01-21 18:36:51 +00002079- Issue #1882: when compiling code from a string, encoding cookies in the
2080 second line of code were not always recognized correctly.
2081
Georg Brandl14404b62008-01-19 19:27:05 +00002082- Issue #1679: "0x" was taken as a valid integer literal.
2083
Georg Brandl6caad7d2008-01-26 14:19:22 +00002084- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002085 added.
2086
Christian Heimesc94e2b52008-01-14 04:13:37 +00002087- sys.float_info / PyFloat_GetInfo: The floating point information
2088 object was converted from a dict to a specialized structseq object.
2089
Georg Brandl3ee81df2008-05-17 18:14:43 +00002090- Patch #1816: Added sys.flags structseq. It exposes the status of
2091 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002092
Georg Brandl3ee81df2008-05-17 18:14:43 +00002093- Objects/structseq.c: Implemented new structseq representation. The
2094 patch makes structseqs (e.g. the return value of os.stat) more
2095 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002096
Georg Brandl3ee81df2008-05-17 18:14:43 +00002097- Patch #1700288: added a type attribute cache that caches method
2098 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002099
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002100- Bug #1776: __import__() no longer accepts filenames on any platform.
2101 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002102
Georg Brandlaed6c662008-01-07 17:25:53 +00002103- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2104
Georg Brandl3ee81df2008-05-17 18:14:43 +00002105- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2106 envvar and sys.dont_write_bytecode attribute. All these can be set
2107 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002108
Georg Brandl3ee81df2008-05-17 18:14:43 +00002109- Improve some exception messages when Windows fails to load an
2110 extension module. Now we get for example '%1 is not a valid Win32
2111 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002112

Georg Brandl3ee81df2008-05-17 18:14:43 +00002115- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2116 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002117
Christian Heimes0a8143f2007-12-18 23:22:54 +00002118- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002119 and INF. float("nan"), float("inf") and float("-inf") now work on
2120 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002121
Georg Brandl3ee81df2008-05-17 18:14:43 +00002122- Compiler now generates simpler and faster code for dictionary
2123 literals. The oparg for BUILD_MAP now indicates an estimated
2124 dictionary size. There is a new opcode, STORE_MAP, for adding
2125 entries to the dictionary.

2143 running, and if the deallocation of its frames somehow calls the
2144 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002145

Georg Brandl3ee81df2008-05-17 18:14:43 +00002154- Patch #1739468: Directories and zipfiles containing a __main__.py
2155 file can now be directly executed by passing their name to the
2156 interpreter. The directory/zipfile is automatically inserted as the
2157 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002158
Georg Brandl3ee81df2008-05-17 18:14:43 +00002159- Issue #1265: Fix a problem with sys.settrace, if the tracing
2160 function uses a generator expression when at the same time the
2161 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002162
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002163- sets and frozensets now have an isdisjoint() method.
2164
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002165- optimize the performance of builtin.sum().
2166
Neal Norwitz44f326e2007-10-05 05:29:17 +00002167- Fix warnings found by the new version of the Coverity checker.
2168
Georg Brandl3ee81df2008-05-17 18:14:43 +00002169- The enumerate() builtin function is no longer bounded to sequences
2170 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2171 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002172
Georg Brandl3ee81df2008-05-17 18:14:43 +00002173- Issue #1686386: Tuple's tp_repr did not take into account the
2174 possibility of having a self-referential tuple, which is possible
2175 from C code. Nor did object's tp_str consider that a type's tp_str
2176 could do something that could lead to an inifinite recursion.
2177 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2178 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002179
Georg Brandl3ee81df2008-05-17 18:14:43 +00002180- Issue #1164: It was possible to trigger deadlock when using the
2181 'print' statement to write to a file since the GIL was not released
2182 as needed. Now PyObject_Print() does the right thing along with
2183 various tp_print implementations of the built-in types and those in
2184 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002185
Georg Brandl3ee81df2008-05-17 18:14:43 +00002186- Issue #1147: Exceptions were directly allowing string exceptions in
2187 their throw() method even though string exceptions no longer
2188 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002189
Georg Brandl3ee81df2008-05-17 18:14:43 +00002190- Issue #1096: Prevent a segfault from getting the repr of a very
2191 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002192
Brett Cannon1e534b52007-09-07 04:18:30 +00002193- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002194 PyObject_Call() never calling back out to Python code to trigger
2195 recursion depth updates/checks. Required the creation of a static
2196 RuntimeError instance in case normalizing an exception put the
2197 recursion check value past its limit. Fixes crashers
2198 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002199
Georg Brandl3ee81df2008-05-17 18:14:43 +00002200- Patch #1031213: Decode source line in SyntaxErrors back to its

2204 with %G.
2205
Georg Brandl3ee81df2008-05-17 18:14:43 +00002206- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002213- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002214 __*__ attributes. (Some already existed, e.g., __doc__ and
2215 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002216
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002217- Add -3 option to the interpreter to warn about features that are
2218 deprecated and will be changed/removed in Python 3.0.
2219
Georg Brandl2134e752007-05-21 20:34:16 +00002220- Patch #1686487: you can now pass any mapping after '**' in function
2221 calls.
2222
Collin Winter62903052007-05-18 23:11:24 +00002223- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002224 "except E as target:". This is to provide forwards compatibility
2225 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002226
Brett Cannon229cee22007-05-05 01:34:02 +00002227- Deprecate BaseException.message as per PEP 352.
2228
Georg Brandl3ee81df2008-05-17 18:14:43 +00002229- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002230 inherited from a builtin base.
2231
Vinay Sajip8549ce32007-05-06 17:53:37 +00002232- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002233 setting a plain string, ie don't expand to single letter identifiers.
2234
Raymond Hettinger13936692007-04-11 18:40:58 +00002235- Request #1191699: Slices can now be pickled.
2236
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002237- Request #1193128: str.translate() now allows a None argument for
2238 translations that only remove characters without re-mapping the
2239 remaining characters.
2240
Georg Brandl5cb76c12007-03-21 09:00:39 +00002241- Patch #1682205: a TypeError while unpacking an iterable is no longer
2242 masked by a generic one with the message "unpack non-sequence".
2243
Neal Norwitzaa754b72007-03-21 06:39:48 +00002244- Remove unused file Python/fmod.c.
2245
Guido van Rossum143b5642007-03-23 04:58:42 +00002246- Bug #1683368: The object.__init__() and object.__new__() methods are
2247 now stricter in rejecting excess arguments. The only time when
2248 either allows excess arguments is when it is not overridden and the
2249 other one is. For backwards compatibility, when both are
2250 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002251 warning later). Also, type.__init__() insists on the same signature
2252 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002253
Georg Brandl3ee81df2008-05-17 18:14:43 +00002254- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2255 object to complex using its __complex__() method before falling back
2256 to the __float__() method. Therefore, the functions in the cmath
2257 module now can operate on objects that define a __complex__()
2258 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002259
Georg Brandl3ee81df2008-05-17 18:14:43 +00002260- Patch #1623563: allow __class__ assignment for classes with
2261 __slots__. The old and the new class are still required to have the
2262 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002263
Georg Brandl3ee81df2008-05-17 18:14:43 +00002264- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002267- Patch #1462488: Python no longer segfaults when
2268 ``object.__reduce_ex__()`` is called with an object that is faking
2269 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002270
Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002274- Patch #1444529: the builtin compile() now accepts keyword arguments.
2275
Georg Brandl7b9c5552007-03-12 14:30:05 +00002276- Bug #1678647: write a newline after printing an exception in any
2277 case, even when converting the value to a string failed.
2278
Georg Brandl871f1bc2007-03-12 13:17:36 +00002279- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280 its argument, if it exists. If not, it will work like before. This
2281 allows customizing the output of dir() in the presence of a
2282 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002283
Collin Winter276887b2007-03-12 16:11:39 +00002284- Patch #922167: Python no longer segfaults when faced with infinitely
2285 self-recursive reload() calls (as reported by bug #742342).
2286
Georg Brandl3ee81df2008-05-17 18:14:43 +00002287- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002290- Patch #1491866: change the complex() constructor to allow
2291 parthensized forms. This means complex(repr(x)) now works instead of
2292 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002293
Georg Brandlaa2321b2007-03-07 00:40:28 +00002294- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002295 makes the filenames the warning module prints much more sensible
2296 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002297
Georg Brandl49aafc92007-03-07 00:34:46 +00002298- Variant of patch #697613: don't exit the interpreter on a SystemExit
2299 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002300 variable is given, but break into the interactive interpreter just

Facundo Batistad918a652007-04-24 13:54:38 +00002805- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002806 the client's request was successfully received, understood, and
2807 accepted. Now in these cases no error is raised in urllib (issue
2808 #1177) and urllib2.

2818 work started with create_connection() and timeout in httplib, and
2819 closes patch #723312.
2820
Vinay Sajip8549ce32007-05-06 17:53:37 +00002821- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista07c78be2007-03-23 18:54:07 +00002824

Georg Brandl3ee81df2008-05-17 18:14:43 +00002847 AttributeError instead of an IOError when the server's response
2848 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002849

2851 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00002854- Patch #1429539: pdb now correctly initializes the __main__ module
2855 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002856 correctly now.
2857

2864
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Patch #1530482: add pydoc.render_doc() which returns the
2866 documentation for a thing instead of paging it to stdout, which

2880
Georg Brandl92a6bae2007-03-13 17:43:32 +00002881- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002882 are set for invalid interpolation sequences that would lead to
2883 errors on reading back those values.

2926 returned string up to the first NUL character.

2937
Georg Brandl3ee81df2008-05-17 18:14:43 +00002938- unittest now verifies more of its assumptions. In particular,
2939 TestCase and TestSuite subclasses (not instances) are no longer
2940 accepted in TestSuite.addTest(). This should cause no
2941 incompatibility since it never made sense with ordinary subclasses
2942 -- the failure just occurred later, with a more cumbersome
2943 exception.

2952 given a unicode argument and os.listdir() returns unicode filenames.
2953
Georg Brandl3ee81df2008-05-17 18:14:43 +00002954- Patch #1673619: setup.py identifies extension modules it doesn't

2956 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003331- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003332 time so that opening a database previously created with the DB_DUP
3333 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3334 opens. Specifically: dictionary assignment to a DB object will
3335 replace all values for a given key when the database allows
3336 duplicate values. DB users should use DB.put(k, v) when they want
3337 to store duplicates; not DB[k] = v.

3344 characters with ASCII value less than 32. Also, it correctly quotes
3345 dots only if they occur on a single line, as opposed to the previous
3346 behavior of quoting dots if they are the second character of any
3347 line.
