58 collecting the oldest generation) so that allocating lots of objects without
59 destroying them does not show quadratic performance. Based on a proposal by
60 Martin von Löwis at
61 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
62
Martin v. Löwisb90304a2009-01-07 18:40:40 +000063- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.

66 an existing .py counterpart, override the co_filename attributes of all
67 code objects if the original filename is obsolete (which can happen if the
68 file has been renamed, moved, or if it is accessed through different paths).

112 (on average) per string allocation.
113
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000114- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

117
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000118- Issue #3689: The list reversed iterator now supports __length_hint__
119 instead of __len__. Behavior now matches other reversed iterators.
120
Benjamin Petersonc078f922008-11-21 22:27:24 +0000121- Issue #4367: Python would segfault during compiling when the unicodedata

123
Vinay Sajip213faca2008-12-03 23:22:58 +0000124- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000125 method on file objects with closefd=False. The file descriptor is still
126 kept open but the file object behaves like a closed file. The ``FileIO``
127 object also got a new readonly attribute ``closefd``.
128
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000129- Issue #4348: Some bytearray methods returned that didn't cause any change to
130 the bytearray, returned the same bytearray instead of a copy.

139 exec statement.
140

142 method does not return iterators for the 4th and 5th items.
143
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000144- Issue #4209: Enabling unicode_literals and the print_function in the same
145 __future__ import didn't work.
146
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000147- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000148 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000149
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000150- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
151 returned a path longer than MAX_PATH. (But It's doubtful this code path is
152 really executed because I cannot move to such directory on win2k)
153
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000154- Issue #4069: When set.remove(element) is used with a set element, the element
155 is temporarily replaced with an equivalent frozenset. But the eventual
156 KeyError would always report the empty frozenset([]) as the missing key. Now
157 it correctly refers to the initial element.
158
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000159- Issue #4509: Various issues surrounding resize of bytearray objects to

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000684- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
685
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000686- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
687 PyString_FromFormat or PyErr_Format to display size_t values. The macro
688 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
689 ``printf`` function, whereas PyString_FromFormat has an independent
690 implementation and uses "%zd" on all platforms for size_t values.
691 This makes a difference on win64, where ``printf`` needs "%Id" to display
692 64bit values.
693
Benjamin Peterson97179b02008-09-09 20:55:01 +0000694- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

698 object; previously an int would be returned for small values. the __long__
699 method is allowed to return either an int or a long, but the behaviour of
700 float objects should not change to respect backward compatibility.
701
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000702- Issue #3751: str.rpartition would perform a left-partition when called with
703 a unicode argument.
704
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000705- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000708 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000709 was correctly parsed but parsing of subsequent arguments failed.
710
Vinay Sajip35e3b032008-09-01 14:33:59 +0000711- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000712 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
713 mechanism. In the process, fix a bug where isinstance() and issubclass(),
714 when given a tuple of classes as second argument, were looking up
715 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
716 type object.
717
Neal Norwitz18aa3882008-08-24 05:04:52 +0000718- Fix crashes on memory allocation failure found with failmalloc.

720- Fix memory leaks found with valgrind and update suppressions file.
721
722- Fix compiler warnings in opt mode which would lead to invalid memory reads.
723
724- Fix problem using wrong name in decimal module reported by pychecker.
725
Christian Heimes7d4c3172008-08-22 19:47:25 +0000726- Silenced another compiler warning about a used but not defined
727 function 'stringlib_contains_obj'.

861-----------------
862
Guido van Rossumf8402962008-08-20 15:01:50 +0000863- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
864 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
865 extensions do not automatically benefit from the class attribute
866 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
867 to their tp_flags field if they care. This is a backwards
868 compatibility feature; in 3.0, all types will use the cache by
869 default.
870
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000871- Keyword arguments can now follow starred arguments. (``f(a, *args,
872 keyword=23)`` is now valid syntax.)
873
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000874- ctypes function pointers that are COM methods have a boolean True
875 value again.

Georg Brandl1e13ea92008-08-11 09:07:59 +0000881- Issue #3537: Fix an assertion failure when an empty but presized dict
882 object was stored in the freelist.
883
Mark Dickinsonb6467572008-08-04 21:30:09 +0000884- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
885 ValueError consistently across platforms.
886
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000887- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
888 (64bit Unix, for example), unichr() would truncate its argument and return
889 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
890
Neal Norwitze7d8be82008-07-31 17:17:14 +0000891- Apply security patches from Apple.
892
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000893- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
894 PyErr_ExceptionMatches returns 0 when an exception occurs there.
895
Antoine Pitrou92f82162008-07-25 22:22:08 +0000896- Issue #1819: function calls with several named parameters are now on

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000899- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
900 the python debugger steps into a class statement: the free variables (local
901 variables defined in an outer scope) would be deleted from the outer scope.
902
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000903- Issue #2620: Overflow checking when allocating or reallocating memory
904 was not always being done properly in some python types and extension
905 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
906 all been updated to perform better checks and places in the code that
907 would previously leak memory on the error path when such an allocation
908 failed have been fixed.

917
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000918- Issue #2234: distutils failed for some versions of the cygwin compiler. The
919 version reported by these tools does not necessarily follow the python
920 version numbering scheme, so the module is less strict when parsing it.
921
Nick Coghlanf70385a2008-08-18 12:42:46 +0000922- Issue #2235: Added Py3k warnings for types which will become unhashable
923 under the stricter __hash__ inheritance rules in 3.0. Several types
924 which did not meet the rules for hash invariants and were already
925 unhashable in 3.0 have now been explicitly flagged as unhashable in
926 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
927 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
928
Brett Cannon88f801d2008-08-18 00:46:22 +0000929- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

939 by using 's*' instead of 't#'.
940
Mark Dickinson3e4caeb2009-02-21 20:27:01 +0000941- Issue #2222: Fixed reference leak when occurred os.rename()

951 after a 302 response in the case of not going through a proxy.
952
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000953- Issue #2676: in the email package, content-type parsing was hanging on
954 pathological input because of quadratic or exponential behaviour of a
955 regular expression.
956
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000957- Issue #3476: binary buffered reading through the new "io" library is now
958 thread-safe.
959
Brett Cannonbf3157b2008-08-14 05:00:03 +0000960- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
961 since mimetools itself is deprecated. Because modules are cached, all
962 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
963
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000964- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +0000966- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
967 menu entries were not deleted.
968
Brett Cannon83e81842008-08-09 23:30:55 +0000969- Copied the implementation of reduce() to _functools.reduce() to have a
970 version that did not raise a DeprecationWarning under -3.
971
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000972- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
973 a MemoryError rather than silently stop the iteration.
974
Guido van Rossum59ce9012008-08-09 14:55:34 +0000975- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
976 to _sre.compile() will now be rejected. This should not affect anybody
977 since the re.compile() function never generates invalid re-bytecode.
978
Skip Montanaroa032bf42008-08-08 22:52:51 +0000979- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
980 upon first access it can be automatically initialized from the csv file if
981 it wasn't initialized during instantiation.
982
Brett Cannon3aa2a492008-08-06 22:28:09 +0000983- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
984 the reload() built-in has been removed.
985
Brett Cannon7e30b672008-08-04 21:52:25 +0000986- Changed code in the following modules/packages to remove warnings raised

995 raised an AttributeError.
996
Benjamin Peterson01a24322008-07-28 23:35:27 +0000997- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000998 asking for a specific length. This problem only affected files opened
999 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001000

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001024- Issue #3394: zipfile.writestr sets external attributes when passed a
1025 file name rather than a ZipInfo instance, so files are extracted with
1026 mode 0600 rather than 000 under Unix.
1027
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001028- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1029 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001040- Issue #2235: the C API function PyObject_HashNotImplemented and its
1041 interaction with the tp_hash slot (added in 2.6b2) are now documented
1042
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001043- Issue #643841: The language reference now provides more detailed
1044 coverage of the lookup process for special methods. The disclaimers
1045 regarding lack of coverage of new-style classes have also been
1046 removed, since the coverage is now fairly reasonable.

1050================================
1051
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001052*Release date: 17-Jul-2008*
1053
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001054Core and Builtins
1055-----------------
1056
Georg Brandl3e483f62008-07-16 22:57:41 +00001057- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1058 its methods now allow for items objects that can be converted to
1059 an integer using operator.index().
1060
Mark Dickinson64b7e502008-07-16 09:40:03 +00001061- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1062 produced a ValueError instead of giving the correct float.
1063
Eric Smitha5fa5a22008-07-16 00:11:49 +00001064- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1065 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1066
Mark Dickinson7103aa42008-07-15 19:08:33 +00001067- Issue #3008: the float type has a new instance method 'float.hex'
1068 and a new class method 'float.fromhex' to convert floating-point
1069 numbers to and from hexadecimal strings, respectively.
1070
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001071- Issue #2235: __hash__ is once again inherited by default. To allow
1072 collections.Hashable to remain meaningful in the presence of the
1073 default hash implementation (object.__hash__), it is now possible
1074 to explicit block inheritance of hash by setting __hash__=None at
1075 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1076 level.
1077
Nick Coghlanb028f502008-07-13 14:52:36 +00001078- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1079 the parent module cannot be found while performing an absolute import.
1080 This means that an incorrectly defined __package__ attribute will
1081 now only prevent relative imports in that module rather than causing
1082 all imports from that module to fail.
1083
Nick Coghlan14ff9942008-07-08 14:21:42 +00001084- Issue #2517: Allow unicode messages in Exceptions again by correctly
1085 bypassing the instance dictionary when looking up __unicode__ on
1086 new-style classes.
1087
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001088- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1089 set to a custom object whose write() method happens to install
1090 another file in sys.stdout.
1091
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001092- Issue #3088: Corrected a race condition in classes derived from
1093 threading.local: the first member set by a thread could be saved in
1094 another thread's dictionary.
1095
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001096- Issue #3004: Minor change to slice.indices(): the start and stop
1097 arguments are now treated identically, making the behaviour easier
1098 to describe and understand. For example, slice(None, -10,
1099 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1100 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1101 10, -1).
1102
Georg Brandl278fc502008-07-19 12:46:12 +00001103- Issue #3219: Calling a function with repeated keyword arguments,
1104 f(a=2, a=23), would not cause a syntax error. This was a regression
1105 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001106
Georg Brandl278fc502008-07-19 12:46:12 +00001107- Issue #2862: Make int and float freelist management consistent with
1108 other freelists. Changes their CompactFreeList apis into
1109 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001110

1112-------
1113
Thomas Heller57adf222008-08-14 19:10:48 +00001114- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1115 api functions without holding the GIL, which could lead to a fatal
1116 error when they failed.
1117
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001118- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001126- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1127 ForkingPickler.register() to resolve conflict with ctypes.
1128
Vinay Sajip51e65192008-07-18 09:01:10 +00001129- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001130
Thomas Heller880f5292008-07-15 19:39:38 +00001131- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1132 a valid dlerror() message.
1133
Thomas Heller2bad6572008-07-15 17:19:50 +00001134- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1135 incomplete structure was created.
1136

1140
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001141- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001142
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001143- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1144 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001145 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001146 content-length. The problem had been corrected in the 2.4 branch, but never
1147 merged into trunk.
1148
Georg Brandle78fbcc2008-07-05 10:13:36 +00001149- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00001157 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001158
Vinay Sajip51e65192008-07-18 09:01:10 +00001159- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001160 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001161
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001162- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1163 handling is now the same as that of other special attributes like __name__).
1164
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001165- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1166 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00001555 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001556
1557 This is controlled by the configure argument ``--with-universal-archs``:
1558
1559 - ``--with-universal-archs=all``: install 4-way universal
1560
1561 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1562
1563 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1564
1565 This option should be used in combination with ``--enable-universalsdk=``.
1566
1567 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00001617- Issue #1631171: Re-implement the 'warnings' module in C (the
1618 original Python code has been kept as backup). This will allow for
1619 using the 'warning's machinery in such places as the parser where
1620 use of pure Python code is not possible. Both the ``showarning()``
1621 and ``formatwarning()`` gain an optional 'line' argument which is
1622 not called by default for backwards-compatibility reasons. Setting
1623 ``warnings.showwarning()`` to an implementation that lacks support
1624 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001687- Issue #2550: The approach used by client/server code for obtaining
1688 ports to listen on in network-oriented tests has been refined in an
1689 effort to facilitate running multiple instances of the entire
1690 regression test suite in parallel without issue.
1691 test_support.bind_port() has been fixed such that it will always
1692 return a unique port -- which wasn't always the case with the
1693 previous implementation, especially if socket options had been set
1694 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1695 new implementation of bind_port() will actually raise an exception
1696 if it is passed an AF_INET/SOCK_STREAM socket with either the
1697 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1698 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1699 the socket it's been passed. This currently only applies to
1700 Windows. This option prevents any other sockets from binding to the
1701 host/port we've bound to, thus removing the possibility of the
1702 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1703 when a second SOCK_STREAM socket binds and accepts to a host/port
1704 that's already been bound by another socket. The optional preferred
1705 port parameter to bind_port() has been removed. Under no
1706 circumstances should tests be hard coding ports!
1707
1708 test_support.find_unused_port() has also been introduced, which will
1709 pass a temporary socket object to bind_port() in order to obtain an
1710 unused port. The temporary socket object is then closed and
1711 deleted, and the port is returned. This method should only be used
1712 for obtaining an unused port in order to pass to an external program
1713 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1714 a parameter to a server-oriented class that doesn't give you direct
1715 access to the underlying socket used.
1716
1717 Finally, test_support.HOST has been introduced, which should be used
1718 for the host argument of any relevant socket calls (i.e. bind and
1719 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001720
1721 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001722 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001723 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1724 test_asynchat and test_socket_ssl.
1725
Georg Brandl3ee81df2008-05-17 18:14:43 +00001726 It is now possible for multiple instances of the regression test

Georg Brandlad61bc82008-02-23 15:11:18 +00001999- Issue #2067: file.__exit__() now calls subclasses' close() method.
2000
2001- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002002
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002003- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002004 issue 215555 for a discussion.
2005
Eric Smitha73fbe72008-02-23 03:09:44 +00002006- Added the future_builtins module, which contains hex() and oct().
2007 These are the PEP 3127 version of these functions, designed to be
2008 compatible with the hex() and oct() builtins from Python 3.0. They
2009 differ slightly in their output formats from the existing, unchanged
2010 Python 2.6 builtins. The expected usage of the future_builtins
2011 module is:
2012 from future_builtins import hex, oct
2013
Eric Smith7ef40bf2008-02-20 23:34:22 +00002014- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2015 exponents for exponents with absolute value < 100. Follows C99
2016 standard. This is a change on Windows, which would use 3 digits.
2017 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2018 so that any alterations it does to the resulting string will be
2019 available in stringlib/formatter.h (for float.__format__).
2020
Eric Smith5a3c1352008-02-19 13:21:56 +00002021- Implemented PEP 3101, Advanced String Formatting. This adds a new
2022 builtin format(); a format() method for str and unicode; a
2023 __format__() method to object, str, unicode, int, long, float, and
2024 datetime; the class string.Formatter; and the C API
2025 PyObject_Format().
2026
Georg Brandl3ee81df2008-05-17 18:14:43 +00002027- Fixed several potential crashes, all caused by specially crafted
2028 __del__ methods exploiting objects in temporarily inconsistent
2029 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002030
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002031- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002032 prevent a possible crash: an Abstract Base Class would try to access
2033 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002034
Georg Brandl3ee81df2008-05-17 18:14:43 +00002035- Fixed repr() and str() of complex numbers with infinity or nan as
2036 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002037
Georg Brandl3ee81df2008-05-17 18:14:43 +00002038- Clear all free lists during a gc.collect() of the highest generation
2039 in order to allow pymalloc to free more arenas. Python may give back
2040 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002041
Georg Brandl3ee81df2008-05-17 18:14:43 +00002042- Issue #2045: Fix an infinite recursion triggered when printing a
2043 subclass of collections.defaultdict, if its default_factory is set
2044 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002045
Christian Heimesf75dbef2008-02-08 00:11:31 +00002046- Fixed a minor memory leak in dictobject.c. The content of the free
2047 list was not freed on interpreter shutdown.
2048
Georg Brandl3ee81df2008-05-17 18:14:43 +00002049- Limit free list of method and builtin function objects to 256
2050 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002051
Georg Brandl3ee81df2008-05-17 18:14:43 +00002052- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2053 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002054 to compact the internal free lists of pre-allocted ints and floats.
2055
Georg Brandl3ee81df2008-05-17 18:14:43 +00002056- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2057 calls. Python expected the return type int but the fork familie
2058 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002059
Georg Brandl3ee81df2008-05-17 18:14:43 +00002060- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2061 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002062
Georg Brandl3ee81df2008-05-17 18:14:43 +00002063- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2064 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002065
Georg Brandl3ee81df2008-05-17 18:14:43 +00002066- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2067 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002068
Georg Brandl3ee81df2008-05-17 18:14:43 +00002069- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2070 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002071
Georg Brandl3ee81df2008-05-17 18:14:43 +00002072- Patch #1473257: generator objects gain a gi_code attribute. This is
2073 the same object as the func_code attribute of the function that
2074 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002075
Georg Brandl3ee81df2008-05-17 18:14:43 +00002076- Issue #1920: "while 0" statements were completely removed by the
2077 compiler, even in the presence of an "else" clause, which is
2078 supposed to be run when the condition is false. Now the compiler
2079 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002080
Guido van Rossumeead05f2008-01-24 18:21:02 +00002081- A few crashers fixed: weakref_in_del.py (issue #1377858);
2082 loosing_dict_ref.py (issue #1303614, test67.py);
2083 borrowed_ref_[34].py (not in tracker).
2084
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002085- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002086 suppressed while an extension is loaded by calling SetErrorMode in
2087 dynload_win.c. The error is still reported properly.
2088
Georg Brandl3ee81df2008-05-17 18:14:43 +00002089- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002090 several extension methods and modules do not work without unicode
2091 support.
2092
Georg Brandl26543b12008-01-21 18:36:51 +00002093- Issue #1882: when compiling code from a string, encoding cookies in the
2094 second line of code were not always recognized correctly.
2095
Georg Brandl14404b62008-01-19 19:27:05 +00002096- Issue #1679: "0x" was taken as a valid integer literal.
2097
Georg Brandl6caad7d2008-01-26 14:19:22 +00002098- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002099 added.
2100
Christian Heimesc94e2b52008-01-14 04:13:37 +00002101- sys.float_info / PyFloat_GetInfo: The floating point information
2102 object was converted from a dict to a specialized structseq object.
2103
Georg Brandl3ee81df2008-05-17 18:14:43 +00002104- Patch #1816: Added sys.flags structseq. It exposes the status of
2105 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002106
Georg Brandl3ee81df2008-05-17 18:14:43 +00002107- Objects/structseq.c: Implemented new structseq representation. The
2108 patch makes structseqs (e.g. the return value of os.stat) more
2109 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002110
Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Patch #1700288: added a type attribute cache that caches method
2112 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002113
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002114- Bug #1776: __import__() no longer accepts filenames on any platform.
2115 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002116

2118
Georg Brandl3ee81df2008-05-17 18:14:43 +00002119- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2120 envvar and sys.dont_write_bytecode attribute. All these can be set
2121 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002122
Georg Brandl3ee81df2008-05-17 18:14:43 +00002123- Improve some exception messages when Windows fails to load an
2124 extension module. Now we get for example '%1 is not a valid Win32
2125 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002126
Georg Brandl3ee81df2008-05-17 18:14:43 +00002127- Bug #1481296: Fixed long(float('nan')) != 0L.

2130 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002131
Christian Heimes0a8143f2007-12-18 23:22:54 +00002132- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002133 and INF. float("nan"), float("inf") and float("-inf") now work on
2134 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002135
Georg Brandl3ee81df2008-05-17 18:14:43 +00002136- Compiler now generates simpler and faster code for dictionary
2137 literals. The oparg for BUILD_MAP now indicates an estimated
2138 dictionary size. There is a new opcode, STORE_MAP, for adding
2139 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002173- Issue #1265: Fix a problem with sys.settrace, if the tracing
2174 function uses a generator expression when at the same time the
2175 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002176
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002177- sets and frozensets now have an isdisjoint() method.
2178

2182
Georg Brandl3ee81df2008-05-17 18:14:43 +00002183- The enumerate() builtin function is no longer bounded to sequences
2184 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2185 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002186
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187- Issue #1686386: Tuple's tp_repr did not take into account the
2188 possibility of having a self-referential tuple, which is possible
2189 from C code. Nor did object's tp_str consider that a type's tp_str
2190 could do something that could lead to an inifinite recursion.
2191 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2192 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002193
Georg Brandl3ee81df2008-05-17 18:14:43 +00002194- Issue #1164: It was possible to trigger deadlock when using the
2195 'print' statement to write to a file since the GIL was not released
2196 as needed. Now PyObject_Print() does the right thing along with
2197 various tp_print implementations of the built-in types and those in
2198 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002199
Georg Brandl3ee81df2008-05-17 18:14:43 +00002200- Issue #1147: Exceptions were directly allowing string exceptions in
2201 their throw() method even though string exceptions no longer
2202 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002203
Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002207- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002208 PyObject_Call() never calling back out to Python code to trigger
2209 recursion depth updates/checks. Required the creation of a static
2210 RuntimeError instance in case normalizing an exception put the
2211 recursion check value past its limit. Fixes crashers
2212 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002213
Georg Brandl3ee81df2008-05-17 18:14:43 +00002214- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002227- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002228 __*__ attributes. (Some already existed, e.g., __doc__ and
2229 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002230
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002231- Add -3 option to the interpreter to warn about features that are
2232 deprecated and will be changed/removed in Python 3.0.
2233
Georg Brandl2134e752007-05-21 20:34:16 +00002234- Patch #1686487: you can now pass any mapping after '**' in function
2235 calls.
2236
Collin Winter62903052007-05-18 23:11:24 +00002237- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002238 "except E as target:". This is to provide forwards compatibility

Brett Cannon229cee22007-05-05 01:34:02 +00002241- Deprecate BaseException.message as per PEP 352.
2242
Georg Brandl3ee81df2008-05-17 18:14:43 +00002243- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002244 inherited from a builtin base.
2245
Vinay Sajip8549ce32007-05-06 17:53:37 +00002246- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002247 setting a plain string, ie don't expand to single letter identifiers.
2248
Raymond Hettinger13936692007-04-11 18:40:58 +00002249- Request #1191699: Slices can now be pickled.
2250
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002251- Request #1193128: str.translate() now allows a None argument for
2252 translations that only remove characters without re-mapping the
2253 remaining characters.
2254
Georg Brandl5cb76c12007-03-21 09:00:39 +00002255- Patch #1682205: a TypeError while unpacking an iterable is no longer

2259
Guido van Rossum143b5642007-03-23 04:58:42 +00002260- Bug #1683368: The object.__init__() and object.__new__() methods are
2261 now stricter in rejecting excess arguments. The only time when
2262 either allows excess arguments is when it is not overridden and the
2263 other one is. For backwards compatibility, when both are
2264 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002265 warning later). Also, type.__init__() insists on the same signature
2266 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002267
Georg Brandl3ee81df2008-05-17 18:14:43 +00002268- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2269 object to complex using its __complex__() method before falling back
2270 to the __float__() method. Therefore, the functions in the cmath
2271 module now can operate on objects that define a __complex__()
2272 method.

2289
Georg Brandl7b9c5552007-03-12 14:30:05 +00002290- Bug #1678647: write a newline after printing an exception in any
2291 case, even when converting the value to a string failed.
2292
Georg Brandl871f1bc2007-03-12 13:17:36 +00002293- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002294 its argument, if it exists. If not, it will work like before. This
2295 allows customizing the output of dir() in the presence of a
2296 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002297
Collin Winter276887b2007-03-12 16:11:39 +00002298- Patch #922167: Python no longer segfaults when faced with infinitely
2299 self-recursive reload() calls (as reported by bug #742342).

2306 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002307
Georg Brandlaa2321b2007-03-07 00:40:28 +00002308- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002309 makes the filenames the warning module prints much more sensible
2310 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002311

Georg Brandl0fca97a2007-03-05 22:28:08 +00002323- Patch #1674228: when assigning a slice (old-style), check for the
2324 sq_ass_slice instead of the sq_slice slot.
2325
Georg Brandl3ee81df2008-05-17 18:14:43 +00002326- When printing an unraisable error, don't print exceptions. before
2327 the name. This duplicates the behavior whening normally printing
2328 exceptions.

2337 created a weakref on itself during a __del__ call for new-style
2338 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00002378- Bug #1545497: when given an explicit base, int() did ignore NULs
2379 embedded in the string to convert.
2380
Georg Brandl846f73a2006-10-08 07:11:54 +00002381- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002429 generator expressions (x for x, in ... ) works again. Fixing this
2430 problem required changing the .pyc magic number. This means that
2431 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002861 AttributeError instead of an IOError when the server's response

2953 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00003238- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3239 with RFC 3207 and forgets any knowledge obtained from the server not
3240 obtained from the TLS negotiation itself. Patch contributed by Bill
3241 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003244 that the SMTP.starttls() caller no longer needs to call ehlo()
3245 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003246 does not claim to support starttls. Adds the
3247 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3328 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3329 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003346 time so that opening a database previously created with the DB_DUP
3347 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3348 opens. Specifically: dictionary assignment to a DB object will
3349 replace all values for a given key when the database allows
3350 duplicate values. DB users should use DB.put(k, v) when they want
3351 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003352

3358 characters with ASCII value less than 32. Also, it correctly quotes
3359 dots only if they occur on a single line, as opposed to the previous
3360 behavior of quoting dots if they are the second character of any
3361 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003362

Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Removed the macfs module. It had been deprecated since Python 2.5.
3768 This lead to the deprecation of macostools.touched() as it relied
3769 solely on macfs and was a no-op under OS X.
