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67 code objects if the original filename is obsolete (which can happen if the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

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

137
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000138- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
139 exec statement.
140
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000141- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
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

692
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000693- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
694 PyString_FromFormat or PyErr_Format to display size_t values. The macro
695 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
696 ``printf`` function, whereas PyString_FromFormat has an independent
697 implementation and uses "%zd" on all platforms for size_t values.
698 This makes a difference on win64, where ``printf`` needs "%Id" to display
699 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +0000701- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

705 object; previously an int would be returned for small values. the __long__
706 method is allowed to return either an int or a long, but the behaviour of
707 float objects should not change to respect backward compatibility.
708
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000709- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +0000715 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000716 was correctly parsed but parsing of subsequent arguments failed.
717
Vinay Sajip35e3b032008-09-01 14:33:59 +0000718- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000719 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
720 mechanism. In the process, fix a bug where isinstance() and issubclass(),
721 when given a tuple of classes as second argument, were looking up
722 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
723 type object.

869
Guido van Rossumf8402962008-08-20 15:01:50 +0000870- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
871 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
872 extensions do not automatically benefit from the class attribute
873 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
874 to their tp_flags field if they care. This is a backwards
875 compatibility feature; in 3.0, all types will use the cache by
876 default.
877
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000878- Keyword arguments can now follow starred arguments. (``f(a, *args,

895 (64bit Unix, for example), unichr() would truncate its argument and return
896 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000900- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
901 PyErr_ExceptionMatches returns 0 when an exception occurs there.
902
Antoine Pitrou92f82162008-07-25 22:22:08 +0000903- Issue #1819: function calls with several named parameters are now on
904 average 35% faster (as measured by pybench).
905
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000906- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
907 the python debugger steps into a class statement: the free variables (local
908 variables defined in an outer scope) would be deleted from the outer scope.
909
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000910- Issue #2620: Overflow checking when allocating or reallocating memory
911 was not always being done properly in some python types and extension
912 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
913 all been updated to perform better checks and places in the code that
914 would previously leak memory on the error path when such an allocation
915 failed have been fixed.

924
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000925- Issue #2234: distutils failed for some versions of the cygwin compiler. The
926 version reported by these tools does not necessarily follow the python
927 version numbering scheme, so the module is less strict when parsing it.
928
Nick Coghlanf70385a2008-08-18 12:42:46 +0000929- Issue #2235: Added Py3k warnings for types which will become unhashable
930 under the stricter __hash__ inheritance rules in 3.0. Several types
931 which did not meet the rules for hash invariants and were already
932 unhashable in 3.0 have now been explicitly flagged as unhashable in
933 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
934 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
935
Brett Cannon88f801d2008-08-18 00:46:22 +0000936- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

961 pathological input because of quadratic or exponential behaviour of a
962 regular expression.
963
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000964- Issue #3476: binary buffered reading through the new "io" library is now
965 thread-safe.
966
Brett Cannonbf3157b2008-08-14 05:00:03 +0000967- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
968 since mimetools itself is deprecated. Because modules are cached, all
969 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
970
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000971- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +0000973- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
974 menu entries were not deleted.
975
Brett Cannon83e81842008-08-09 23:30:55 +0000976- Copied the implementation of reduce() to _functools.reduce() to have a
977 version that did not raise a DeprecationWarning under -3.
978
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000979- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
980 a MemoryError rather than silently stop the iteration.
981
Guido van Rossum59ce9012008-08-09 14:55:34 +0000982- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
983 to _sre.compile() will now be rejected. This should not affect anybody
984 since the re.compile() function never generates invalid re-bytecode.
985
Skip Montanaroa032bf42008-08-08 22:52:51 +0000986- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
987 upon first access it can be automatically initialized from the csv file if
988 it wasn't initialized during instantiation.
989
Brett Cannon3aa2a492008-08-06 22:28:09 +0000990- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
991 the reload() built-in has been removed.
992
Brett Cannon7e30b672008-08-04 21:52:25 +0000993- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00001005 asking for a specific length. This problem only affected files opened
1006 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001031- Issue #3394: zipfile.writestr sets external attributes when passed a
1032 file name rather than a ZipInfo instance, so files are extracted with
1033 mode 0600 rather than 000 under Unix.
1034
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001035- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1036 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001047- Issue #2235: the C API function PyObject_HashNotImplemented and its
1048 interaction with the tp_hash slot (added in 2.6b2) are now documented
1049
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001050- Issue #643841: The language reference now provides more detailed
1051 coverage of the lookup process for special methods. The disclaimers
1052 regarding lack of coverage of new-style classes have also been
1053 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001056What's New in Python 2.6 beta 2?
1057================================
1058
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001059*Release date: 17-Jul-2008*
1060
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001061Core and Builtins
1062-----------------
1063
Georg Brandl3e483f62008-07-16 22:57:41 +00001064- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1065 its methods now allow for items objects that can be converted to
1066 an integer using operator.index().
1067
Mark Dickinson64b7e502008-07-16 09:40:03 +00001068- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1069 produced a ValueError instead of giving the correct float.
1070
Eric Smitha5fa5a22008-07-16 00:11:49 +00001071- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1072 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1073
Mark Dickinson7103aa42008-07-15 19:08:33 +00001074- Issue #3008: the float type has a new instance method 'float.hex'
1075 and a new class method 'float.fromhex' to convert floating-point
1076 numbers to and from hexadecimal strings, respectively.
1077
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001078- Issue #2235: __hash__ is once again inherited by default. To allow
1079 collections.Hashable to remain meaningful in the presence of the
1080 default hash implementation (object.__hash__), it is now possible
1081 to explicit block inheritance of hash by setting __hash__=None at
1082 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1083 level.
1084
Nick Coghlanb028f502008-07-13 14:52:36 +00001085- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1086 the parent module cannot be found while performing an absolute import.
1087 This means that an incorrectly defined __package__ attribute will
1088 now only prevent relative imports in that module rather than causing
1089 all imports from that module to fail.
1090
Nick Coghlan14ff9942008-07-08 14:21:42 +00001091- Issue #2517: Allow unicode messages in Exceptions again by correctly
1092 bypassing the instance dictionary when looking up __unicode__ on
1093 new-style classes.
1094
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001095- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1096 set to a custom object whose write() method happens to install
1097 another file in sys.stdout.
1098
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001099- Issue #3088: Corrected a race condition in classes derived from
1100 threading.local: the first member set by a thread could be saved in
1101 another thread's dictionary.
1102
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001103- Issue #3004: Minor change to slice.indices(): the start and stop
1104 arguments are now treated identically, making the behaviour easier
1105 to describe and understand. For example, slice(None, -10,
1106 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1107 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1108 10, -1).
1109
Georg Brandl278fc502008-07-19 12:46:12 +00001110- Issue #3219: Calling a function with repeated keyword arguments,
1111 f(a=2, a=23), would not cause a syntax error. This was a regression
1112 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001113
Georg Brandl278fc502008-07-19 12:46:12 +00001114- Issue #2862: Make int and float freelist management consistent with
1115 other freelists. Changes their CompactFreeList apis into
1116 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001117

1119-------
1120
Thomas Heller57adf222008-08-14 19:10:48 +00001121- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1122 api functions without holding the GIL, which could lead to a fatal
1123 error when they failed.
1124
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001125- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001133- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1134 ForkingPickler.register() to resolve conflict with ctypes.
1135
Vinay Sajip51e65192008-07-18 09:01:10 +00001136- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001137
Thomas Heller880f5292008-07-15 19:39:38 +00001138- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1139 a valid dlerror() message.
1140
Thomas Heller2bad6572008-07-15 17:19:50 +00001141- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1142 incomplete structure was created.
1143
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001144- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00001146- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1147
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001148- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001149
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001150- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1151 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001152 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001153 content-length. The problem had been corrected in the 2.4 branch, but never
1154 merged into trunk.
1155
Georg Brandle78fbcc2008-07-05 10:13:36 +00001156- Issue #2663: add filtering capability to shutil.copytree().

1162- Issue #1746: Correct handling of zipfile archive comments (previously
1163 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001164 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001165
Vinay Sajip51e65192008-07-18 09:01:10 +00001166- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001167 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001168
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001169- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1170 handling is now the same as that of other special attributes like __name__).
1171
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001172- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1173 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00001562 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001563
1564 This is controlled by the configure argument ``--with-universal-archs``:
1565
1566 - ``--with-universal-archs=all``: install 4-way universal
1567
1568 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1569
1570 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1571
1572 This option should be used in combination with ``--enable-universalsdk=``.
1573
1574 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 +00001624- Issue #1631171: Re-implement the 'warnings' module in C (the
1625 original Python code has been kept as backup). This will allow for
1626 using the 'warning's machinery in such places as the parser where
1627 use of pure Python code is not possible. Both the ``showarning()``
1628 and ``formatwarning()`` gain an optional 'line' argument which is
1629 not called by default for backwards-compatibility reasons. Setting
1630 ``warnings.showwarning()`` to an implementation that lacks support
1631 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001694- Issue #2550: The approach used by client/server code for obtaining
1695 ports to listen on in network-oriented tests has been refined in an
1696 effort to facilitate running multiple instances of the entire
1697 regression test suite in parallel without issue.
1698 test_support.bind_port() has been fixed such that it will always
1699 return a unique port -- which wasn't always the case with the
1700 previous implementation, especially if socket options had been set
1701 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1702 new implementation of bind_port() will actually raise an exception
1703 if it is passed an AF_INET/SOCK_STREAM socket with either the
1704 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1705 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1706 the socket it's been passed. This currently only applies to
1707 Windows. This option prevents any other sockets from binding to the
1708 host/port we've bound to, thus removing the possibility of the
1709 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1710 when a second SOCK_STREAM socket binds and accepts to a host/port
1711 that's already been bound by another socket. The optional preferred
1712 port parameter to bind_port() has been removed. Under no
1713 circumstances should tests be hard coding ports!
1714
1715 test_support.find_unused_port() has also been introduced, which will
1716 pass a temporary socket object to bind_port() in order to obtain an
1717 unused port. The temporary socket object is then closed and
1718 deleted, and the port is returned. This method should only be used
1719 for obtaining an unused port in order to pass to an external program
1720 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1721 a parameter to a server-oriented class that doesn't give you direct
1722 access to the underlying socket used.
1723
1724 Finally, test_support.HOST has been introduced, which should be used
1725 for the host argument of any relevant socket calls (i.e. bind and
1726 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001727
1728 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001729 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

1731 test_asynchat and test_socket_ssl.
1732
Georg Brandl3ee81df2008-05-17 18:14:43 +00001733 It is now possible for multiple instances of the regression test
1734 suite to run in parallel without issue.

2000Core and builtins
2001-----------------
2002
Fred Drakea8ee94b2008-03-01 02:45:07 +00002003- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002004 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002005
Georg Brandlad61bc82008-02-23 15:11:18 +00002006- Issue #2067: file.__exit__() now calls subclasses' close() method.
2007
2008- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002009
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002010- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002011 issue 215555 for a discussion.
2012
Eric Smitha73fbe72008-02-23 03:09:44 +00002013- Added the future_builtins module, which contains hex() and oct().
2014 These are the PEP 3127 version of these functions, designed to be
2015 compatible with the hex() and oct() builtins from Python 3.0. They
2016 differ slightly in their output formats from the existing, unchanged
2017 Python 2.6 builtins. The expected usage of the future_builtins
2018 module is:
2019 from future_builtins import hex, oct
2020
Eric Smith7ef40bf2008-02-20 23:34:22 +00002021- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2022 exponents for exponents with absolute value < 100. Follows C99
2023 standard. This is a change on Windows, which would use 3 digits.
2024 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2025 so that any alterations it does to the resulting string will be
2026 available in stringlib/formatter.h (for float.__format__).
2027
Eric Smith5a3c1352008-02-19 13:21:56 +00002028- Implemented PEP 3101, Advanced String Formatting. This adds a new
2029 builtin format(); a format() method for str and unicode; a
2030 __format__() method to object, str, unicode, int, long, float, and
2031 datetime; the class string.Formatter; and the C API
2032 PyObject_Format().
2033
Georg Brandl3ee81df2008-05-17 18:14:43 +00002034- Fixed several potential crashes, all caused by specially crafted
2035 __del__ methods exploiting objects in temporarily inconsistent
2036 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002037
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002038- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002039 prevent a possible crash: an Abstract Base Class would try to access
2040 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002041
Georg Brandl3ee81df2008-05-17 18:14:43 +00002042- Fixed repr() and str() of complex numbers with infinity or nan as
2043 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002044
Georg Brandl3ee81df2008-05-17 18:14:43 +00002045- Clear all free lists during a gc.collect() of the highest generation
2046 in order to allow pymalloc to free more arenas. Python may give back
2047 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002048
Georg Brandl3ee81df2008-05-17 18:14:43 +00002049- Issue #2045: Fix an infinite recursion triggered when printing a
2050 subclass of collections.defaultdict, if its default_factory is set
2051 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002052
Christian Heimesf75dbef2008-02-08 00:11:31 +00002053- Fixed a minor memory leak in dictobject.c. The content of the free
2054 list was not freed on interpreter shutdown.
2055
Georg Brandl3ee81df2008-05-17 18:14:43 +00002056- Limit free list of method and builtin function objects to 256
2057 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002058
Georg Brandl3ee81df2008-05-17 18:14:43 +00002059- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2060 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002061 to compact the internal free lists of pre-allocted ints and floats.
2062
Georg Brandl3ee81df2008-05-17 18:14:43 +00002063- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2064 calls. Python expected the return type int but the fork familie
2065 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002066
Georg Brandl3ee81df2008-05-17 18:14:43 +00002067- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2068 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002069
Georg Brandl3ee81df2008-05-17 18:14:43 +00002070- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2071 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002072
Georg Brandl3ee81df2008-05-17 18:14:43 +00002073- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2074 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002075
Georg Brandl3ee81df2008-05-17 18:14:43 +00002076- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2077 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002078
Georg Brandl3ee81df2008-05-17 18:14:43 +00002079- Patch #1473257: generator objects gain a gi_code attribute. This is
2080 the same object as the func_code attribute of the function that
2081 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002082
Georg Brandl3ee81df2008-05-17 18:14:43 +00002083- Issue #1920: "while 0" statements were completely removed by the
2084 compiler, even in the presence of an "else" clause, which is
2085 supposed to be run when the condition is false. Now the compiler
2086 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002087
Guido van Rossumeead05f2008-01-24 18:21:02 +00002088- A few crashers fixed: weakref_in_del.py (issue #1377858);
2089 loosing_dict_ref.py (issue #1303614, test67.py);
2090 borrowed_ref_[34].py (not in tracker).
2091
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002092- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002093 suppressed while an extension is loaded by calling SetErrorMode in
2094 dynload_win.c. The error is still reported properly.
2095
Georg Brandl3ee81df2008-05-17 18:14:43 +00002096- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002097 several extension methods and modules do not work without unicode
2098 support.
2099
Georg Brandl26543b12008-01-21 18:36:51 +00002100- Issue #1882: when compiling code from a string, encoding cookies in the
2101 second line of code were not always recognized correctly.
2102
Georg Brandl14404b62008-01-19 19:27:05 +00002103- Issue #1679: "0x" was taken as a valid integer literal.
2104
Georg Brandl6caad7d2008-01-26 14:19:22 +00002105- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002106 added.
2107
Christian Heimesc94e2b52008-01-14 04:13:37 +00002108- sys.float_info / PyFloat_GetInfo: The floating point information
2109 object was converted from a dict to a specialized structseq object.
2110
Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Patch #1816: Added sys.flags structseq. It exposes the status of
2112 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002113
Georg Brandl3ee81df2008-05-17 18:14:43 +00002114- Objects/structseq.c: Implemented new structseq representation. The
2115 patch makes structseqs (e.g. the return value of os.stat) more
2116 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002117
Georg Brandl3ee81df2008-05-17 18:14:43 +00002118- Patch #1700288: added a type attribute cache that caches method
2119 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002120
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002121- Bug #1776: __import__() no longer accepts filenames on any platform.
2122 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002123
Georg Brandlaed6c662008-01-07 17:25:53 +00002124- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2125
Georg Brandl3ee81df2008-05-17 18:14:43 +00002126- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2127 envvar and sys.dont_write_bytecode attribute. All these can be set
2128 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002129
Georg Brandl3ee81df2008-05-17 18:14:43 +00002130- Improve some exception messages when Windows fails to load an
2131 extension module. Now we get for example '%1 is not a valid Win32
2132 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002133
Georg Brandl3ee81df2008-05-17 18:14:43 +00002134- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002136- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2137 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002138
Christian Heimes0a8143f2007-12-18 23:22:54 +00002139- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002140 and INF. float("nan"), float("inf") and float("-inf") now work on
2141 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002142
Georg Brandl3ee81df2008-05-17 18:14:43 +00002143- Compiler now generates simpler and faster code for dictionary
2144 literals. The oparg for BUILD_MAP now indicates an estimated
2145 dictionary size. There is a new opcode, STORE_MAP, for adding
2146 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- Issue #1638: %zd configure test fails on Linux.

2176 file can now be directly executed by passing their name to the
2177 interpreter. The directory/zipfile is automatically inserted as the
2178 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002179
Georg Brandl3ee81df2008-05-17 18:14:43 +00002180- Issue #1265: Fix a problem with sys.settrace, if the tracing
2181 function uses a generator expression when at the same time the
2182 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002183
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002184- sets and frozensets now have an isdisjoint() method.
2185
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002186- optimize the performance of builtin.sum().
2187
Neal Norwitz44f326e2007-10-05 05:29:17 +00002188- Fix warnings found by the new version of the Coverity checker.
2189
Georg Brandl3ee81df2008-05-17 18:14:43 +00002190- The enumerate() builtin function is no longer bounded to sequences
2191 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2192 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002193
Georg Brandl3ee81df2008-05-17 18:14:43 +00002194- Issue #1686386: Tuple's tp_repr did not take into account the
2195 possibility of having a self-referential tuple, which is possible
2196 from C code. Nor did object's tp_str consider that a type's tp_str
2197 could do something that could lead to an inifinite recursion.
2198 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2199 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002200
Georg Brandl3ee81df2008-05-17 18:14:43 +00002201- Issue #1164: It was possible to trigger deadlock when using the
2202 'print' statement to write to a file since the GIL was not released
2203 as needed. Now PyObject_Print() does the right thing along with
2204 various tp_print implementations of the built-in types and those in
2205 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002206
Georg Brandl3ee81df2008-05-17 18:14:43 +00002207- Issue #1147: Exceptions were directly allowing string exceptions in
2208 their throw() method even though string exceptions no longer
2209 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002210
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002214- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002215 PyObject_Call() never calling back out to Python code to trigger
2216 recursion depth updates/checks. Required the creation of a static
2217 RuntimeError instance in case normalizing an exception put the
2218 recursion check value past its limit. Fixes crashers
2219 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002220

Neal Norwitz0ac60192007-05-27 04:08:54 +00002234- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002235 __*__ attributes. (Some already existed, e.g., __doc__ and
2236 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002237
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002238- Add -3 option to the interpreter to warn about features that are
2239 deprecated and will be changed/removed in Python 3.0.
2240
Georg Brandl2134e752007-05-21 20:34:16 +00002241- Patch #1686487: you can now pass any mapping after '**' in function
2242 calls.
2243
Collin Winter62903052007-05-18 23:11:24 +00002244- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245 "except E as target:". This is to provide forwards compatibility
2246 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002247
Brett Cannon229cee22007-05-05 01:34:02 +00002248- Deprecate BaseException.message as per PEP 352.
2249
Georg Brandl3ee81df2008-05-17 18:14:43 +00002250- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002251 inherited from a builtin base.
2252
Vinay Sajip8549ce32007-05-06 17:53:37 +00002253- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002254 setting a plain string, ie don't expand to single letter identifiers.
2255
Raymond Hettinger13936692007-04-11 18:40:58 +00002256- Request #1191699: Slices can now be pickled.
2257
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002258- Request #1193128: str.translate() now allows a None argument for
2259 translations that only remove characters without re-mapping the
2260 remaining characters.
2261
Georg Brandl5cb76c12007-03-21 09:00:39 +00002262- Patch #1682205: a TypeError while unpacking an iterable is no longer
2263 masked by a generic one with the message "unpack non-sequence".
2264
Neal Norwitzaa754b72007-03-21 06:39:48 +00002265- Remove unused file Python/fmod.c.
2266
Guido van Rossum143b5642007-03-23 04:58:42 +00002267- Bug #1683368: The object.__init__() and object.__new__() methods are
2268 now stricter in rejecting excess arguments. The only time when
2269 either allows excess arguments is when it is not overridden and the
2270 other one is. For backwards compatibility, when both are
2271 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002272 warning later). Also, type.__init__() insists on the same signature
2273 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2276 object to complex using its __complex__() method before falling back
2277 to the __float__() method. Therefore, the functions in the cmath
2278 module now can operate on objects that define a __complex__()
2279 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002280
Georg Brandl3ee81df2008-05-17 18:14:43 +00002281- Patch #1623563: allow __class__ assignment for classes with
2282 __slots__. The old and the new class are still required to have the
2283 same slot names.

2290 its type.

2296
Georg Brandl7b9c5552007-03-12 14:30:05 +00002297- Bug #1678647: write a newline after printing an exception in any
2298 case, even when converting the value to a string failed.
2299
Georg Brandl871f1bc2007-03-12 13:17:36 +00002300- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002301 its argument, if it exists. If not, it will work like before. This
2302 allows customizing the output of dir() in the presence of a
2303 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002304
Collin Winter276887b2007-03-12 16:11:39 +00002305- Patch #922167: Python no longer segfaults when faced with infinitely
2306 self-recursive reload() calls (as reported by bug #742342).
2307
Georg Brandl3ee81df2008-05-17 18:14:43 +00002308- Patch #1675981: remove unreachable code from ``type.__new__()``

2312 parthensized forms. This means complex(repr(x)) now works instead of
2313 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002314
Georg Brandlaa2321b2007-03-07 00:40:28 +00002315- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002316 makes the filenames the warning module prints much more sensible
2317 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002318
Georg Brandl49aafc92007-03-07 00:34:46 +00002319- Variant of patch #697613: don't exit the interpreter on a SystemExit
2320 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002321 variable is given, but break into the interactive interpreter just
2322 like on other exceptions or normal program exit.

2328 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002329
Georg Brandl0fca97a2007-03-05 22:28:08 +00002330- Patch #1674228: when assigning a slice (old-style), check for the
2331 sq_ass_slice instead of the sq_slice slot.
2332
Georg Brandl3ee81df2008-05-17 18:14:43 +00002333- When printing an unraisable error, don't print exceptions. before
2334 the name. This duplicates the behavior whening normally printing
2335 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002336
Georg Brandl3ee81df2008-05-17 18:14:43 +00002337- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002343- Bug #1377858: Fix the segfaulting of the interpreter when an object
2344 created a weakref on itself during a __del__ call for new-style
2345 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002868 AttributeError instead of an IOError when the server's response
2869 didn't contain a valid HTTP status line.

2901
Georg Brandl92a6bae2007-03-13 17:43:32 +00002902- Patch #1603688: ConfigParser.SafeConfigParser now checks values that

2960 TestCase and TestSuite subclasses (not instances) are no longer

3243 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003244
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3246 with RFC 3207 and forgets any knowledge obtained from the server not
3247 obtained from the TLS negotiation itself. Patch contributed by Bill
3248 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003251 that the SMTP.starttls() caller no longer needs to call ehlo()
3252 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003253 does not claim to support starttls. Adds the
3254 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3335 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3336 silently miscode subclasses of those types. Now, it raises a
3337 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003338

Georg Brandl3ee81df2008-05-17 18:14:43 +00003353 time so that opening a database previously created with the DB_DUP
3354 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3355 opens. Specifically: dictionary assignment to a DB object will
3356 replace all values for a given key when the database allows
3357 duplicate values. DB users should use DB.put(k, v) when they want
3358 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003359

3365 characters with ASCII value less than 32. Also, it correctly quotes
3366 dots only if they occur on a single line, as opposed to the previous
3367 behavior of quoting dots if they are the second character of any
3368 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003369

3706 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003707
3708- Patch #1720595: add T_BOOL to the range of structmember types.
3709
3710- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3711 ``PyFloat_GetInfo()`` to the float API.
3712
Georg Brandl3ee81df2008-05-17 18:14:43 +00003713- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3714 of w# format code incorrectly truncated the length to an int, even
3715 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3716 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003717
Georg Brandl3ee81df2008-05-17 18:14:43 +00003718- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3719 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003721- PEP 3123: Provide forward compatibility with Python 3.0, while
3722 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3723 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003724
Georg Brandl3ee81df2008-05-17 18:14:43 +00003725- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3726 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003727
3728- Patch #1733960: Allow T_LONGLONG to accept ints.
3729
3730- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3731
Christian Heimes000a0742008-01-03 22:16:32 +00003732- Added a new API function ``PyImport_ImportModuleNoBlock``.
3733
Georg Brandl6caad7d2008-01-26 14:19:22 +00003734- Bug #1637022: Prefix AST symbols with _Py_.
3735
3736- Fix some leftovers from the conversion from int to Py_ssize_t
3737 (relevant to strings and sequences of more than 2**31 items).
3738
3739- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3740 outside of pystate.c and should not be necessary.
3741
Georg Brandl3ee81df2008-05-17 18:14:43 +00003742- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3743 absolute imports. In earlier versions they might have used relative
3744 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003745
Georg Brandl3ee81df2008-05-17 18:14:43 +00003746- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3747 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003748
Georg Brandl3ee81df2008-05-17 18:14:43 +00003749- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3750 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003756- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3757 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3758 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3759 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003774- Removed the macfs module. It had been deprecated since Python 2.5.
3775 This lead to the deprecation of macostools.touched() as it relied
3776 solely on macfs and was a no-op under OS X.
