28 were suppressing all exceptions. These include list(), filter(), map(),
29 zip(), and bytearray().
30
Benjamin Peterson596d3062009-01-19 15:42:23 +000031- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
32 functions.
33
Benjamin Peterson5848d1f2009-01-19 00:08:08 +000034- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

40 to str, bytes and bytearray could be optimized away by the compiler, letting
41 the interpreter segfault instead of raising an error.
42
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +000043- Issue #3720: Fix a crash when an iterator modifies its class and removes its

49
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +000050- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
51 collecting the oldest generation) so that allocating lots of objects without
52 destroying them does not show quadratic performance. Based on a proposal by
53 Martin von Löwis at
54 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
55
Martin v. Löwisb90304a2009-01-07 18:40:40 +000056- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.

59 an existing .py counterpart, override the co_filename attributes of all
60 code objects if the original filename is obsolete (which can happen if the
61 file has been renamed, moved, or if it is accessed through different paths).
62 Patch by Ziga Seilnacht and Jean-Paul Calderone.
63
Martin v. Löwis5344c992009-01-02 20:32:55 +000064- Issue #4075: Use OutputDebugStringW in Py_FatalError.
65
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +000066- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
67 file with `str' filename on Windows.

Antoine Pitrouaa687902009-01-01 14:11:22 +000069- Issue #3680: Reference cycles created through a dict, set or deque iterator
70 did not get collected.
71
Nick Coghlan180e4002008-12-30 01:18:48 +000072- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
73 where the tp_hash and tp_dict slots are both NULL.
74
Benjamin Peterson7af65562008-12-29 17:56:58 +000075- Issue #4764: With io.open, IOError.filename is set when trying to open a
76 directory on POSIX systems.
77
Benjamin Petersonfe231b02008-12-29 17:47:42 +000078- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

97 context manager returns a value that cannot be converted to a bool.
98
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +000099- Issue #4597: Fixed several opcodes that weren't always propagating
100 exceptions.
101
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000102- Issue #4445: Replace "sizeof(PyStringObject)" with
103 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
104 str instances. On a typical machine this saves 3 bytes of memory
105 (on average) per string allocation.
106
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000107- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
108 interpreter to abort ("Fatal Python error: Could not reset the stack!")
109 instead of throwing a MemoryError.
110
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000111- Issue #3689: The list reversed iterator now supports __length_hint__
112 instead of __len__. Behavior now matches other reversed iterators.
113
Benjamin Petersonc078f922008-11-21 22:27:24 +0000114- Issue #4367: Python would segfault during compiling when the unicodedata
115 module couldn't be imported and \N escapes were present.
116
Vinay Sajip213faca2008-12-03 23:22:58 +0000117- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000118 method on file objects with closefd=False. The file descriptor is still
119 kept open but the file object behaves like a closed file. The ``FileIO``
120 object also got a new readonly attribute ``closefd``.
121
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000122- Issue #4348: Some bytearray methods returned that didn't cause any change to
123 the bytearray, returned the same bytearray instead of a copy.
124
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000125- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

130
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000131- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
132 exec statement.
133
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000134- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
135 method does not return iterators for the 4th and 5th items.
136
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000137- Issue #4209: Enabling unicode_literals and the print_function in the same
138 __future__ import didn't work.
139
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000140- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000141 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000142
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000143- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
144 returned a path longer than MAX_PATH. (But It's doubtful this code path is
145 really executed because I cannot move to such directory on win2k)
146
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000147- Issue #4069: When set.remove(element) is used with a set element, the element
148 is temporarily replaced with an equivalent frozenset. But the eventual
149 KeyError would always report the empty frozenset([]) as the missing key. Now
150 it correctly refers to the initial element.
151
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000152- Issue #4509: Various issues surrounding resize of bytearray objects to
153 which there are buffer exports.
154
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000155- Issue #4748: Lambda generators no longer return a value.
156

163 from the package_data and the data_files metadata.
164
Tarek Ziadé13699002009-02-14 14:10:23 +0000165- Issue #5257: refactored all tests in distutils, so they use

178
Tarek Ziadé74fbf602009-02-10 12:31:09 +0000179- Issue #3386: distutils.sysconfig.get_python_lib prefix argument was ignored

181
Brett Cannon28d10882009-02-10 02:07:38 +0000182- Issue #5128: Make compileall properly inspect bytecode to determine if needs

267
Antoine Pitroue741cc62009-01-21 00:45:36 +0000268- Issue #5008: When a file is opened in append mode with the new IO library,
269 do an explicit seek to the end of file (so that e.g. tell() returns the
270 file size rather than 0). This is consistent with the behaviour of the
271 traditional 2.x file object.
272
Vinay Sajip5fb11b22009-01-20 22:43:17 +0000273- Issue #5013: Fixed a bug in FileHandler which occurred when the delay

282 it is possible to segfault the interpreter.
283

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000643- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
644
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000645- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
646 PyString_FromFormat or PyErr_Format to display size_t values. The macro
647 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
648 ``printf`` function, whereas PyString_FromFormat has an independent
649 implementation and uses "%zd" on all platforms for size_t values.
650 This makes a difference on win64, where ``printf`` needs "%Id" to display
651 64bit values.
652
Benjamin Peterson97179b02008-09-09 20:55:01 +0000653- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
654 error.
655
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000656- Issue #3777: long() applied to a float object now always return a long
657 object; previously an int would be returned for small values. the __long__
658 method is allowed to return either an int or a long, but the behaviour of
659 float objects should not change to respect backward compatibility.
660
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000661- Issue #3751: str.rpartition would perform a left-partition when called with
662 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000667 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000668 was correctly parsed but parsing of subsequent arguments failed.
669
Vinay Sajip35e3b032008-09-01 14:33:59 +0000670- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000671 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
672 mechanism. In the process, fix a bug where isinstance() and issubclass(),
673 when given a tuple of classes as second argument, were looking up
674 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
675 type object.

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

Barry Warsaw07a4a382008-08-21 01:15:08 +0000817*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000818
819Core and Builtins
820-----------------
821
Guido van Rossumf8402962008-08-20 15:01:50 +0000822- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
823 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
824 extensions do not automatically benefit from the class attribute
825 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
826 to their tp_flags field if they care. This is a backwards
827 compatibility feature; in 3.0, all types will use the cache by
828 default.
829
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000830- Keyword arguments can now follow starred arguments. (``f(a, *args,
831 keyword=23)`` is now valid syntax.)
832
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000833- ctypes function pointers that are COM methods have a boolean True
834 value again.
835
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000836- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
837 by denying s# to parse objects that have a releasebuffer procedure,
838 and introducing s*.
839
Georg Brandl1e13ea92008-08-11 09:07:59 +0000840- Issue #3537: Fix an assertion failure when an empty but presized dict
841 object was stored in the freelist.
842
Mark Dickinsonb6467572008-08-04 21:30:09 +0000843- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
844 ValueError consistently across platforms.
845
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000846- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
847 (64bit Unix, for example), unichr() would truncate its argument and return
848 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
849
Neal Norwitze7d8be82008-07-31 17:17:14 +0000850- Apply security patches from Apple.
851
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000852- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
853 PyErr_ExceptionMatches returns 0 when an exception occurs there.
854
Antoine Pitrou92f82162008-07-25 22:22:08 +0000855- Issue #1819: function calls with several named parameters are now on
856 average 35% faster (as measured by pybench).
857
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000858- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
859 the python debugger steps into a class statement: the free variables (local
860 variables defined in an outer scope) would be deleted from the outer scope.
861
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000862- Issue #2620: Overflow checking when allocating or reallocating memory
863 was not always being done properly in some python types and extension
864 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
865 all been updated to perform better checks and places in the code that
866 would previously leak memory on the error path when such an allocation
867 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +0000874- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
875 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
876
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000877- Issue #2234: distutils failed for some versions of the cygwin compiler. The
878 version reported by these tools does not necessarily follow the python
879 version numbering scheme, so the module is less strict when parsing it.
880
Nick Coghlanf70385a2008-08-18 12:42:46 +0000881- Issue #2235: Added Py3k warnings for types which will become unhashable
882 under the stricter __hash__ inheritance rules in 3.0. Several types
883 which did not meet the rules for hash invariants and were already
884 unhashable in 3.0 have now been explicitly flagged as unhashable in
885 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
886 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
887
Brett Cannon88f801d2008-08-18 00:46:22 +0000888- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
889 imported into the module but exposed as part of the module's API.

896
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000897- Issue #3575: Incremental decoder's decode function now takes bytearray
898 by using 's*' instead of 't#'.
899
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000900- Issue #2222: Fixed reference leak when occured os.rename()

1001
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001002- Issue #643841: The language reference now provides more detailed

1010
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001011*Release date: 17-Jul-2008*

1014-----------------
1015
Georg Brandl3e483f62008-07-16 22:57:41 +00001016- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1017 its methods now allow for items objects that can be converted to
1018 an integer using operator.index().
1019
Mark Dickinson64b7e502008-07-16 09:40:03 +00001020- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1021 produced a ValueError instead of giving the correct float.
1022
Eric Smitha5fa5a22008-07-16 00:11:49 +00001023- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1024 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1025
Mark Dickinson7103aa42008-07-15 19:08:33 +00001026- Issue #3008: the float type has a new instance method 'float.hex'
1027 and a new class method 'float.fromhex' to convert floating-point
1028 numbers to and from hexadecimal strings, respectively.
1029
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001030- Issue #2235: __hash__ is once again inherited by default. To allow
1031 collections.Hashable to remain meaningful in the presence of the
1032 default hash implementation (object.__hash__), it is now possible
1033 to explicit block inheritance of hash by setting __hash__=None at
1034 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1035 level.
1036
Nick Coghlanb028f502008-07-13 14:52:36 +00001037- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1038 the parent module cannot be found while performing an absolute import.
1039 This means that an incorrectly defined __package__ attribute will
1040 now only prevent relative imports in that module rather than causing
1041 all imports from that module to fail.
1042
Nick Coghlan14ff9942008-07-08 14:21:42 +00001043- Issue #2517: Allow unicode messages in Exceptions again by correctly
1044 bypassing the instance dictionary when looking up __unicode__ on
1045 new-style classes.

1048 set to a custom object whose write() method happens to install
1049 another file in sys.stdout.

1052 threading.local: the first member set by a thread could be saved in
1053 another thread's dictionary.
1054
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001055- Issue #3004: Minor change to slice.indices(): the start and stop
1056 arguments are now treated identically, making the behaviour easier
1057 to describe and understand. For example, slice(None, -10,
1058 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1059 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1060 10, -1).
1061
Georg Brandl278fc502008-07-19 12:46:12 +00001062- Issue #3219: Calling a function with repeated keyword arguments,
1063 f(a=2, a=23), would not cause a syntax error. This was a regression
1064 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001065
Georg Brandl278fc502008-07-19 12:46:12 +00001066- Issue #2862: Make int and float freelist management consistent with
1067 other freelists. Changes their CompactFreeList apis into
1068 ClearFreeList apis and calls them via gc.collect().

1074 api functions without holding the GIL, which could lead to a fatal
1075 error when they failed.
1076
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001077- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001102- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1103 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001104 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001105 content-length. The problem had been corrected in the 2.4 branch, but never
1106 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001121- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1123
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001124- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Brett Cannonb61d8012008-05-11 23:39:04 +00001510- ``Lib/lib-old`` is now added to sys.path.
1511
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001512- On MacOS X it is now possible to install the framework in 64-bit
1513 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001514 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001515
1516 This is controlled by the configure argument ``--with-universal-archs``:
1517
1518 - ``--with-universal-archs=all``: install 4-way universal
1519
1520 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1521
1522 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1523
1524 This option should be used in combination with ``--enable-universalsdk=``.
1525
1526 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 +00001576- Issue #1631171: Re-implement the 'warnings' module in C (the
1577 original Python code has been kept as backup). This will allow for
1578 using the 'warning's machinery in such places as the parser where
1579 use of pure Python code is not possible. Both the ``showarning()``
1580 and ``formatwarning()`` gain an optional 'line' argument which is
1581 not called by default for backwards-compatibility reasons. Setting
1582 ``warnings.showwarning()`` to an implementation that lacks support
1583 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001625- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001626 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001646- Issue #2550: The approach used by client/server code for obtaining
1647 ports to listen on in network-oriented tests has been refined in an
1648 effort to facilitate running multiple instances of the entire
1649 regression test suite in parallel without issue.
1650 test_support.bind_port() has been fixed such that it will always
1651 return a unique port -- which wasn't always the case with the
1652 previous implementation, especially if socket options had been set
1653 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1654 new implementation of bind_port() will actually raise an exception
1655 if it is passed an AF_INET/SOCK_STREAM socket with either the
1656 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1657 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1658 the socket it's been passed. This currently only applies to
1659 Windows. This option prevents any other sockets from binding to the
1660 host/port we've bound to, thus removing the possibility of the
1661 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1662 when a second SOCK_STREAM socket binds and accepts to a host/port
1663 that's already been bound by another socket. The optional preferred
1664 port parameter to bind_port() has been removed. Under no
1665 circumstances should tests be hard coding ports!
1666
1667 test_support.find_unused_port() has also been introduced, which will
1668 pass a temporary socket object to bind_port() in order to obtain an
1669 unused port. The temporary socket object is then closed and
1670 deleted, and the port is returned. This method should only be used
1671 for obtaining an unused port in order to pass to an external program
1672 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1673 a parameter to a server-oriented class that doesn't give you direct
1674 access to the underlying socket used.
1675
1676 Finally, test_support.HOST has been introduced, which should be used
1677 for the host argument of any relevant socket calls (i.e. bind and
1678 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001679
1680 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001681 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001682 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1683 test_asynchat and test_socket_ssl.
1684
Georg Brandl3ee81df2008-05-17 18:14:43 +00001685 It is now possible for multiple instances of the regression test
1686 suite to run in parallel without issue.

1953-----------------
1954
Fred Drakea8ee94b2008-03-01 02:45:07 +00001955- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001956 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00001961
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001962- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001963 issue 215555 for a discussion.
1964
Eric Smitha73fbe72008-02-23 03:09:44 +00001965- Added the future_builtins module, which contains hex() and oct().
1966 These are the PEP 3127 version of these functions, designed to be
1967 compatible with the hex() and oct() builtins from Python 3.0. They
1968 differ slightly in their output formats from the existing, unchanged
1969 Python 2.6 builtins. The expected usage of the future_builtins
1970 module is:
1971 from future_builtins import hex, oct
1972
Eric Smith7ef40bf2008-02-20 23:34:22 +00001973- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1974 exponents for exponents with absolute value < 100. Follows C99
1975 standard. This is a change on Windows, which would use 3 digits.
1976 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1977 so that any alterations it does to the resulting string will be
1978 available in stringlib/formatter.h (for float.__format__).
1979
Eric Smith5a3c1352008-02-19 13:21:56 +00001980- Implemented PEP 3101, Advanced String Formatting. This adds a new
1981 builtin format(); a format() method for str and unicode; a
1982 __format__() method to object, str, unicode, int, long, float, and
1983 datetime; the class string.Formatter; and the C API
1984 PyObject_Format().
1985
Georg Brandl3ee81df2008-05-17 18:14:43 +00001986- Fixed several potential crashes, all caused by specially crafted
1987 __del__ methods exploiting objects in temporarily inconsistent
1988 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001989
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001990- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001991 prevent a possible crash: an Abstract Base Class would try to access
1992 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001993

Georg Brandl3ee81df2008-05-17 18:14:43 +00001997- Clear all free lists during a gc.collect() of the highest generation
1998 in order to allow pymalloc to free more arenas. Python may give back
1999 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002000
Georg Brandl3ee81df2008-05-17 18:14:43 +00002001- Issue #2045: Fix an infinite recursion triggered when printing a
2002 subclass of collections.defaultdict, if its default_factory is set
2003 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002004
Christian Heimesf75dbef2008-02-08 00:11:31 +00002005- Fixed a minor memory leak in dictobject.c. The content of the free
2006 list was not freed on interpreter shutdown.
2007
Georg Brandl3ee81df2008-05-17 18:14:43 +00002008- Limit free list of method and builtin function objects to 256
2009 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002010
Georg Brandl3ee81df2008-05-17 18:14:43 +00002011- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2012 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002013 to compact the internal free lists of pre-allocted ints and floats.
2014
Georg Brandl3ee81df2008-05-17 18:14:43 +00002015- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2016 calls. Python expected the return type int but the fork familie
2017 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002018
Georg Brandl3ee81df2008-05-17 18:14:43 +00002019- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2020 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002021
Georg Brandl3ee81df2008-05-17 18:14:43 +00002022- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2023 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002024
Georg Brandl3ee81df2008-05-17 18:14:43 +00002025- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002028- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2029 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002030
Georg Brandl3ee81df2008-05-17 18:14:43 +00002031- Patch #1473257: generator objects gain a gi_code attribute. This is
2032 the same object as the func_code attribute of the function that
2033 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002034
Georg Brandl3ee81df2008-05-17 18:14:43 +00002035- Issue #1920: "while 0" statements were completely removed by the
2036 compiler, even in the presence of an "else" clause, which is
2037 supposed to be run when the condition is false. Now the compiler
2038 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002039
Guido van Rossumeead05f2008-01-24 18:21:02 +00002040- A few crashers fixed: weakref_in_del.py (issue #1377858);
2041 loosing_dict_ref.py (issue #1303614, test67.py);
2042 borrowed_ref_[34].py (not in tracker).
2043
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002044- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002045 suppressed while an extension is loaded by calling SetErrorMode in
2046 dynload_win.c. The error is still reported properly.
2047
Georg Brandl3ee81df2008-05-17 18:14:43 +00002048- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002049 several extension methods and modules do not work without unicode
2050 support.
2051
Georg Brandl26543b12008-01-21 18:36:51 +00002052- Issue #1882: when compiling code from a string, encoding cookies in the
2053 second line of code were not always recognized correctly.
2054
Georg Brandl14404b62008-01-19 19:27:05 +00002055- Issue #1679: "0x" was taken as a valid integer literal.
2056
Georg Brandl6caad7d2008-01-26 14:19:22 +00002057- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002058 added.
2059
Christian Heimesc94e2b52008-01-14 04:13:37 +00002060- sys.float_info / PyFloat_GetInfo: The floating point information
2061 object was converted from a dict to a specialized structseq object.
2062
Georg Brandl3ee81df2008-05-17 18:14:43 +00002063- Patch #1816: Added sys.flags structseq. It exposes the status of
2064 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002065
Georg Brandl3ee81df2008-05-17 18:14:43 +00002066- Objects/structseq.c: Implemented new structseq representation. The
2067 patch makes structseqs (e.g. the return value of os.stat) more
2068 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002069
Georg Brandl3ee81df2008-05-17 18:14:43 +00002070- Patch #1700288: added a type attribute cache that caches method
2071 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002072
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002073- Bug #1776: __import__() no longer accepts filenames on any platform.
2074 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002075
Georg Brandlaed6c662008-01-07 17:25:53 +00002076- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2077
Georg Brandl3ee81df2008-05-17 18:14:43 +00002078- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2079 envvar and sys.dont_write_bytecode attribute. All these can be set
2080 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002081
Georg Brandl3ee81df2008-05-17 18:14:43 +00002082- Improve some exception messages when Windows fails to load an
2083 extension module. Now we get for example '%1 is not a valid Win32
2084 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002085

Christian Heimes0a8143f2007-12-18 23:22:54 +00002091- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002092 and INF. float("nan"), float("inf") and float("-inf") now work on
2093 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002094
Georg Brandl3ee81df2008-05-17 18:14:43 +00002095- Compiler now generates simpler and faster code for dictionary
2096 literals. The oparg for BUILD_MAP now indicates an estimated
2097 dictionary size. There is a new opcode, STORE_MAP, for adding
2098 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002127- Patch #1739468: Directories and zipfiles containing a __main__.py
2128 file can now be directly executed by passing their name to the
2129 interpreter. The directory/zipfile is automatically inserted as the
2130 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002131
Georg Brandl3ee81df2008-05-17 18:14:43 +00002132- Issue #1265: Fix a problem with sys.settrace, if the tracing
2133 function uses a generator expression when at the same time the
2134 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002135
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002136- sets and frozensets now have an isdisjoint() method.
2137

2139
Neal Norwitz44f326e2007-10-05 05:29:17 +00002140- Fix warnings found by the new version of the Coverity checker.
2141
Georg Brandl3ee81df2008-05-17 18:14:43 +00002142- The enumerate() builtin function is no longer bounded to sequences
2143 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2144 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002145
Georg Brandl3ee81df2008-05-17 18:14:43 +00002146- Issue #1686386: Tuple's tp_repr did not take into account the
2147 possibility of having a self-referential tuple, which is possible
2148 from C code. Nor did object's tp_str consider that a type's tp_str
2149 could do something that could lead to an inifinite recursion.
2150 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2151 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002152
Georg Brandl3ee81df2008-05-17 18:14:43 +00002153- Issue #1164: It was possible to trigger deadlock when using the
2154 'print' statement to write to a file since the GIL was not released
2155 as needed. Now PyObject_Print() does the right thing along with
2156 various tp_print implementations of the built-in types and those in
2157 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002158
Georg Brandl3ee81df2008-05-17 18:14:43 +00002159- Issue #1147: Exceptions were directly allowing string exceptions in
2160 their throw() method even though string exceptions no longer
2161 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002162
Georg Brandl3ee81df2008-05-17 18:14:43 +00002163- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002165
Brett Cannon1e534b52007-09-07 04:18:30 +00002166- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002167 PyObject_Call() never calling back out to Python code to trigger
2168 recursion depth updates/checks. Required the creation of a static
2169 RuntimeError instance in case normalizing an exception put the
2170 recursion check value past its limit. Fixes crashers
2171 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002172

Neal Norwitz0ac60192007-05-27 04:08:54 +00002186- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187 __*__ attributes. (Some already existed, e.g., __doc__ and
2188 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002189
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002190- Add -3 option to the interpreter to warn about features that are
2191 deprecated and will be changed/removed in Python 3.0.
2192
Georg Brandl2134e752007-05-21 20:34:16 +00002193- Patch #1686487: you can now pass any mapping after '**' in function
2194 calls.
2195
Collin Winter62903052007-05-18 23:11:24 +00002196- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002197 "except E as target:". This is to provide forwards compatibility
2198 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002199
Brett Cannon229cee22007-05-05 01:34:02 +00002200- Deprecate BaseException.message as per PEP 352.
2201
Georg Brandl3ee81df2008-05-17 18:14:43 +00002202- Issue #1303614: don't expose object's __dict__ when the dict is

2204
Vinay Sajip8549ce32007-05-06 17:53:37 +00002205- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002206 setting a plain string, ie don't expand to single letter identifiers.
2207
Raymond Hettinger13936692007-04-11 18:40:58 +00002208- Request #1191699: Slices can now be pickled.
2209
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002210- Request #1193128: str.translate() now allows a None argument for
2211 translations that only remove characters without re-mapping the
2212 remaining characters.
2213
Georg Brandl5cb76c12007-03-21 09:00:39 +00002214- Patch #1682205: a TypeError while unpacking an iterable is no longer
2215 masked by a generic one with the message "unpack non-sequence".
2216
Neal Norwitzaa754b72007-03-21 06:39:48 +00002217- Remove unused file Python/fmod.c.
2218
Guido van Rossum143b5642007-03-23 04:58:42 +00002219- Bug #1683368: The object.__init__() and object.__new__() methods are
2220 now stricter in rejecting excess arguments. The only time when
2221 either allows excess arguments is when it is not overridden and the
2222 other one is. For backwards compatibility, when both are
2223 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002224 warning later). Also, type.__init__() insists on the same signature
2225 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002227- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2228 object to complex using its __complex__() method before falling back
2229 to the __float__() method. Therefore, the functions in the cmath
2230 module now can operate on objects that define a __complex__()
2231 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002233- Patch #1623563: allow __class__ assignment for classes with
2234 __slots__. The old and the new class are still required to have the
2235 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002236

Georg Brandl3ee81df2008-05-17 18:14:43 +00002253 its argument, if it exists. If not, it will work like before. This
2254 allows customizing the output of dir() in the presence of a

Georg Brandlaa2321b2007-03-07 00:40:28 +00002267- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00002337- Bug #1545497: when given an explicit base, int() did ignore NULs
2338 embedded in the string to convert.
2339
Georg Brandl846f73a2006-10-08 07:11:54 +00002340- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00002370- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002388 generator expressions (x for x, in ... ) works again. Fixing this
2389 problem required changing the .pyc magic number. This means that
2390 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002820 AttributeError instead of an IOError when the server's response
2821 didn't contain a valid HTTP status line.

Georg Brandl92a6bae2007-03-13 17:43:32 +00002854- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855 are set for invalid interpolation sequences that would lead to

2912 TestCase and TestSuite subclasses (not instances) are no longer

3287 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3288 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003305 time so that opening a database previously created with the DB_DUP
3306 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3307 opens. Specifically: dictionary assignment to a DB object will
3308 replace all values for a given key when the database allows
3309 duplicate values. DB users should use DB.put(k, v) when they want
3310 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003311

3317 characters with ASCII value less than 32. Also, it correctly quotes
3318 dots only if they occur on a single line, as opposed to the previous
3319 behavior of quoting dots if they are the second character of any
3320 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003321

3350 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00003351
