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60 code objects if the original filename is obsolete (which can happen if the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

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__

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.

163
Tarek Ziadé7dd53392009-02-16 21:38:01 +0000164- Issue #2279: distutils.sdist.add_defaults now add files
165 from the package_data and the data_files metadata.
166
Tarek Ziadé13699002009-02-14 14:10:23 +0000167- Issue #5257: refactored all tests in distutils, so they use
168 support.TempdirManager, to avoid writing in the tests directory.
169
Tarek Ziadé2432b0b2009-02-13 23:00:43 +0000170- Issue #4524: distutils build_script command failed with --with-suffix=3.

177
Thomas Heller3689ae22009-02-10 18:43:01 +0000178- Issue #5203: Fixed ctypes segfaults when passing a unicode string to a
179 function without argtypes (only occurs if HAVE_USABLE_WCHAR_T is false).
180
Tarek Ziadé74fbf602009-02-10 12:31:09 +0000181- Issue #3386: distutils.sysconfig.get_python_lib prefix argument was ignored
182 under NT and OS2. Patch by Philip Jenvey.
183
Brett Cannon28d10882009-02-10 02:07:38 +0000184- Issue #5128: Make compileall properly inspect bytecode to determine if needs
185 to be recreated. This avoids a timing hole thanks to the old reliance on the
186 ctime of the files involved.
187
Guilherme Poloa66cf5b2009-02-09 20:50:27 +0000188- Issue #5122: Synchronize tk load failure check to prevent a potential

248 and compress().
Raymond Hettinger2bcb8e92009-01-25 21:04:14 +0000249

Jesse Nollerf6da8d12009-01-23 14:04:41 +0000267 --without-threads argument. When this occurs, _multiprocessing will
268 be disabled, and not compiled.
269
Antoine Pitroue741cc62009-01-21 00:45:36 +0000270- Issue #5008: When a file is opened in append mode with the new IO library,
271 do an explicit seek to the end of file (so that e.g. tell() returns the
272 file size rather than 0). This is consistent with the behaviour of the
273 traditional 2.x file object.
274
Vinay Sajip5fb11b22009-01-20 22:43:17 +0000275- Issue #5013: Fixed a bug in FileHandler which occurred when the delay

283 for *nix machines for negative handles and large int handles. Without this check
284 it is possible to segfault the interpreter.
285
Jesse Noller6ab22152009-01-18 02:45:38 +0000286- Issue #4449: AssertionError in mp_benchmarks.py, caused by an underlying issue

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000645- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
646
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000647- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
648 PyString_FromFormat or PyErr_Format to display size_t values. The macro
649 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
650 ``printf`` function, whereas PyString_FromFormat has an independent
651 implementation and uses "%zd" on all platforms for size_t values.
652 This makes a difference on win64, where ``printf`` needs "%Id" to display
653 64bit values.
654
Benjamin Peterson97179b02008-09-09 20:55:01 +0000655- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
656 error.
657
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000658- Issue #3777: long() applied to a float object now always return a long
659 object; previously an int would be returned for small values. the __long__
660 method is allowed to return either an int or a long, but the behaviour of
661 float objects should not change to respect backward compatibility.
662
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000663- Issue #3751: str.rpartition would perform a left-partition when called with
664 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000669 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000670 was correctly parsed but parsing of subsequent arguments failed.
671
Vinay Sajip35e3b032008-09-01 14:33:59 +0000672- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000673 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
674 mechanism. In the process, fix a bug where isinstance() and issubclass(),
675 when given a tuple of classes as second argument, were looking up
676 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
677 type object.

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

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000816What's New in Python 2.6 beta 3?
817================================
818
Barry Warsaw07a4a382008-08-21 01:15:08 +0000819*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000820
821Core and Builtins
822-----------------
823
Guido van Rossumf8402962008-08-20 15:01:50 +0000824- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
825 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
826 extensions do not automatically benefit from the class attribute
827 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
828 to their tp_flags field if they care. This is a backwards
829 compatibility feature; in 3.0, all types will use the cache by
830 default.
831
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000832- Keyword arguments can now follow starred arguments. (``f(a, *args,
833 keyword=23)`` is now valid syntax.)
834
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000835- ctypes function pointers that are COM methods have a boolean True
836 value again.
837
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000838- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
839 by denying s# to parse objects that have a releasebuffer procedure,
840 and introducing s*.
841
Georg Brandl1e13ea92008-08-11 09:07:59 +0000842- Issue #3537: Fix an assertion failure when an empty but presized dict
843 object was stored in the freelist.
844
Mark Dickinsonb6467572008-08-04 21:30:09 +0000845- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
846 ValueError consistently across platforms.
847
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000848- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
849 (64bit Unix, for example), unichr() would truncate its argument and return
850 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
851
Neal Norwitze7d8be82008-07-31 17:17:14 +0000852- Apply security patches from Apple.
853
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000854- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
855 PyErr_ExceptionMatches returns 0 when an exception occurs there.
856
Antoine Pitrou92f82162008-07-25 22:22:08 +0000857- Issue #1819: function calls with several named parameters are now on
858 average 35% faster (as measured by pybench).
859
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000860- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
861 the python debugger steps into a class statement: the free variables (local
862 variables defined in an outer scope) would be deleted from the outer scope.
863
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000864- Issue #2620: Overflow checking when allocating or reallocating memory
865 was not always being done properly in some python types and extension
866 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
867 all been updated to perform better checks and places in the code that
868 would previously leak memory on the error path when such an allocation
869 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +0000876- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
877 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
878
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000879- Issue #2234: distutils failed for some versions of the cygwin compiler. The
880 version reported by these tools does not necessarily follow the python
881 version numbering scheme, so the module is less strict when parsing it.
882
Nick Coghlanf70385a2008-08-18 12:42:46 +0000883- Issue #2235: Added Py3k warnings for types which will become unhashable
884 under the stricter __hash__ inheritance rules in 3.0. Several types
885 which did not meet the rules for hash invariants and were already
886 unhashable in 3.0 have now been explicitly flagged as unhashable in
887 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
888 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
889
Brett Cannon88f801d2008-08-18 00:46:22 +0000890- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
891 imported into the module but exposed as part of the module's API.
892
Brett Cannon7b96f072008-08-18 00:41:11 +0000893- Remove an unneeded import of abc.ABCMeta from 'inspect'.

898
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000899- Issue #3575: Incremental decoder's decode function now takes bytearray
900 by using 's*' instead of 't#'.

1016-----------------
1017
Georg Brandl3e483f62008-07-16 22:57:41 +00001018- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1019 its methods now allow for items objects that can be converted to
1020 an integer using operator.index().
1021
Mark Dickinson64b7e502008-07-16 09:40:03 +00001022- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1023 produced a ValueError instead of giving the correct float.
1024
Eric Smitha5fa5a22008-07-16 00:11:49 +00001025- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1026 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1027
Mark Dickinson7103aa42008-07-15 19:08:33 +00001028- Issue #3008: the float type has a new instance method 'float.hex'
1029 and a new class method 'float.fromhex' to convert floating-point
1030 numbers to and from hexadecimal strings, respectively.
1031
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001032- Issue #2235: __hash__ is once again inherited by default. To allow
1033 collections.Hashable to remain meaningful in the presence of the
1034 default hash implementation (object.__hash__), it is now possible
1035 to explicit block inheritance of hash by setting __hash__=None at
1036 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1037 level.
1038
Nick Coghlanb028f502008-07-13 14:52:36 +00001039- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1040 the parent module cannot be found while performing an absolute import.
1041 This means that an incorrectly defined __package__ attribute will
1042 now only prevent relative imports in that module rather than causing
1043 all imports from that module to fail.
1044
Nick Coghlan14ff9942008-07-08 14:21:42 +00001045- Issue #2517: Allow unicode messages in Exceptions again by correctly
1046 bypassing the instance dictionary when looking up __unicode__ on
1047 new-style classes.

1050 set to a custom object whose write() method happens to install
1051 another file in sys.stdout.

1054 threading.local: the first member set by a thread could be saved in
1055 another thread's dictionary.
1056
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001057- Issue #3004: Minor change to slice.indices(): the start and stop
1058 arguments are now treated identically, making the behaviour easier
1059 to describe and understand. For example, slice(None, -10,
1060 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1061 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1062 10, -1).
1063
Georg Brandl278fc502008-07-19 12:46:12 +00001064- Issue #3219: Calling a function with repeated keyword arguments,
1065 f(a=2, a=23), would not cause a syntax error. This was a regression
1066 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001067
Georg Brandl278fc502008-07-19 12:46:12 +00001068- Issue #2862: Make int and float freelist management consistent with
1069 other freelists. Changes their CompactFreeList apis into
1070 ClearFreeList apis and calls them via gc.collect().

1076 api functions without holding the GIL, which could lead to a fatal
1077 error when they failed.
1078
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001079- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001104- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1105 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001106 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001107 content-length. The problem had been corrected in the 2.4 branch, but never
1108 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001123- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1125
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001126- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

1513
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001514- On MacOS X it is now possible to install the framework in 64-bit
1515 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001516 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001517
1518 This is controlled by the configure argument ``--with-universal-archs``:
1519
1520 - ``--with-universal-archs=all``: install 4-way universal
1521
1522 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1523
1524 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1525
1526 This option should be used in combination with ``--enable-universalsdk=``.
1527
1528 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 +00001578- Issue #1631171: Re-implement the 'warnings' module in C (the
1579 original Python code has been kept as backup). This will allow for
1580 using the 'warning's machinery in such places as the parser where
1581 use of pure Python code is not possible. Both the ``showarning()``
1582 and ``formatwarning()`` gain an optional 'line' argument which is
1583 not called by default for backwards-compatibility reasons. Setting
1584 ``warnings.showwarning()`` to an implementation that lacks support
1585 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001627- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001628 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001648- Issue #2550: The approach used by client/server code for obtaining
1649 ports to listen on in network-oriented tests has been refined in an
1650 effort to facilitate running multiple instances of the entire
1651 regression test suite in parallel without issue.
1652 test_support.bind_port() has been fixed such that it will always
1653 return a unique port -- which wasn't always the case with the
1654 previous implementation, especially if socket options had been set
1655 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1656 new implementation of bind_port() will actually raise an exception
1657 if it is passed an AF_INET/SOCK_STREAM socket with either the
1658 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1659 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1660 the socket it's been passed. This currently only applies to
1661 Windows. This option prevents any other sockets from binding to the
1662 host/port we've bound to, thus removing the possibility of the
1663 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1664 when a second SOCK_STREAM socket binds and accepts to a host/port
1665 that's already been bound by another socket. The optional preferred
1666 port parameter to bind_port() has been removed. Under no
1667 circumstances should tests be hard coding ports!
1668
1669 test_support.find_unused_port() has also been introduced, which will
1670 pass a temporary socket object to bind_port() in order to obtain an
1671 unused port. The temporary socket object is then closed and
1672 deleted, and the port is returned. This method should only be used
1673 for obtaining an unused port in order to pass to an external program
1674 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1675 a parameter to a server-oriented class that doesn't give you direct
1676 access to the underlying socket used.
1677
1678 Finally, test_support.HOST has been introduced, which should be used
1679 for the host argument of any relevant socket calls (i.e. bind and
1680 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001681
1682 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001683 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001684 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1685 test_asynchat and test_socket_ssl.
1686
Georg Brandl3ee81df2008-05-17 18:14:43 +00001687 It is now possible for multiple instances of the regression test
1688 suite to run in parallel without issue.

1955-----------------
1956
Fred Drakea8ee94b2008-03-01 02:45:07 +00001957- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001958 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00001963
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001964- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001965 issue 215555 for a discussion.
1966
Eric Smitha73fbe72008-02-23 03:09:44 +00001967- Added the future_builtins module, which contains hex() and oct().
1968 These are the PEP 3127 version of these functions, designed to be
1969 compatible with the hex() and oct() builtins from Python 3.0. They
1970 differ slightly in their output formats from the existing, unchanged
1971 Python 2.6 builtins. The expected usage of the future_builtins
1972 module is:
1973 from future_builtins import hex, oct
1974
Eric Smith7ef40bf2008-02-20 23:34:22 +00001975- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1976 exponents for exponents with absolute value < 100. Follows C99
1977 standard. This is a change on Windows, which would use 3 digits.
1978 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1979 so that any alterations it does to the resulting string will be
1980 available in stringlib/formatter.h (for float.__format__).
1981
Eric Smith5a3c1352008-02-19 13:21:56 +00001982- Implemented PEP 3101, Advanced String Formatting. This adds a new
1983 builtin format(); a format() method for str and unicode; a
1984 __format__() method to object, str, unicode, int, long, float, and
1985 datetime; the class string.Formatter; and the C API
1986 PyObject_Format().
1987
Georg Brandl3ee81df2008-05-17 18:14:43 +00001988- Fixed several potential crashes, all caused by specially crafted
1989 __del__ methods exploiting objects in temporarily inconsistent
1990 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001991
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001992- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001993 prevent a possible crash: an Abstract Base Class would try to access
1994 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001995
Georg Brandl3ee81df2008-05-17 18:14:43 +00001996- Fixed repr() and str() of complex numbers with infinity or nan as
1997 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001999- Clear all free lists during a gc.collect() of the highest generation
2000 in order to allow pymalloc to free more arenas. Python may give back
2001 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002002
Georg Brandl3ee81df2008-05-17 18:14:43 +00002003- Issue #2045: Fix an infinite recursion triggered when printing a
2004 subclass of collections.defaultdict, if its default_factory is set
2005 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002006
Christian Heimesf75dbef2008-02-08 00:11:31 +00002007- Fixed a minor memory leak in dictobject.c. The content of the free
2008 list was not freed on interpreter shutdown.
2009
Georg Brandl3ee81df2008-05-17 18:14:43 +00002010- Limit free list of method and builtin function objects to 256
2011 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002012
Georg Brandl3ee81df2008-05-17 18:14:43 +00002013- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2014 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002015 to compact the internal free lists of pre-allocted ints and floats.
2016
Georg Brandl3ee81df2008-05-17 18:14:43 +00002017- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2018 calls. Python expected the return type int but the fork familie
2019 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002020
Georg Brandl3ee81df2008-05-17 18:14:43 +00002021- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2022 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002023
Georg Brandl3ee81df2008-05-17 18:14:43 +00002024- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2025 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002026
Georg Brandl3ee81df2008-05-17 18:14:43 +00002027- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002030- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2031 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002032
Georg Brandl3ee81df2008-05-17 18:14:43 +00002033- Patch #1473257: generator objects gain a gi_code attribute. This is
2034 the same object as the func_code attribute of the function that
2035 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002036
Georg Brandl3ee81df2008-05-17 18:14:43 +00002037- Issue #1920: "while 0" statements were completely removed by the
2038 compiler, even in the presence of an "else" clause, which is
2039 supposed to be run when the condition is false. Now the compiler
2040 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002041
Guido van Rossumeead05f2008-01-24 18:21:02 +00002042- A few crashers fixed: weakref_in_del.py (issue #1377858);
2043 loosing_dict_ref.py (issue #1303614, test67.py);
2044 borrowed_ref_[34].py (not in tracker).
2045
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002046- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002047 suppressed while an extension is loaded by calling SetErrorMode in
2048 dynload_win.c. The error is still reported properly.
2049
Georg Brandl3ee81df2008-05-17 18:14:43 +00002050- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002051 several extension methods and modules do not work without unicode
2052 support.
2053
Georg Brandl26543b12008-01-21 18:36:51 +00002054- Issue #1882: when compiling code from a string, encoding cookies in the
2055 second line of code were not always recognized correctly.
2056
Georg Brandl14404b62008-01-19 19:27:05 +00002057- Issue #1679: "0x" was taken as a valid integer literal.
2058
Georg Brandl6caad7d2008-01-26 14:19:22 +00002059- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002060 added.
2061
Christian Heimesc94e2b52008-01-14 04:13:37 +00002062- sys.float_info / PyFloat_GetInfo: The floating point information
2063 object was converted from a dict to a specialized structseq object.
2064
Georg Brandl3ee81df2008-05-17 18:14:43 +00002065- Patch #1816: Added sys.flags structseq. It exposes the status of
2066 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002067
Georg Brandl3ee81df2008-05-17 18:14:43 +00002068- Objects/structseq.c: Implemented new structseq representation. The
2069 patch makes structseqs (e.g. the return value of os.stat) more
2070 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002071
Georg Brandl3ee81df2008-05-17 18:14:43 +00002072- Patch #1700288: added a type attribute cache that caches method
2073 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002074
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002075- Bug #1776: __import__() no longer accepts filenames on any platform.
2076 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002077
Georg Brandlaed6c662008-01-07 17:25:53 +00002078- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2079
Georg Brandl3ee81df2008-05-17 18:14:43 +00002080- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2081 envvar and sys.dont_write_bytecode attribute. All these can be set
2082 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002083
Georg Brandl3ee81df2008-05-17 18:14:43 +00002084- Improve some exception messages when Windows fails to load an
2085 extension module. Now we get for example '%1 is not a valid Win32
2086 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002087

2091 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002092
Christian Heimes0a8143f2007-12-18 23:22:54 +00002093- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002094 and INF. float("nan"), float("inf") and float("-inf") now work on
2095 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002096
Georg Brandl3ee81df2008-05-17 18:14:43 +00002097- Compiler now generates simpler and faster code for dictionary
2098 literals. The oparg for BUILD_MAP now indicates an estimated
2099 dictionary size. There is a new opcode, STORE_MAP, for adding
2100 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002101

Georg Brandl3ee81df2008-05-17 18:14:43 +00002129- Patch #1739468: Directories and zipfiles containing a __main__.py
2130 file can now be directly executed by passing their name to the
2131 interpreter. The directory/zipfile is automatically inserted as the
2132 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002133
Georg Brandl3ee81df2008-05-17 18:14:43 +00002134- Issue #1265: Fix a problem with sys.settrace, if the tracing
2135 function uses a generator expression when at the same time the
2136 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002137
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002138- sets and frozensets now have an isdisjoint() method.
2139

2141
Neal Norwitz44f326e2007-10-05 05:29:17 +00002142- Fix warnings found by the new version of the Coverity checker.
2143
Georg Brandl3ee81df2008-05-17 18:14:43 +00002144- The enumerate() builtin function is no longer bounded to sequences
2145 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2146 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- Issue #1686386: Tuple's tp_repr did not take into account the
2149 possibility of having a self-referential tuple, which is possible
2150 from C code. Nor did object's tp_str consider that a type's tp_str
2151 could do something that could lead to an inifinite recursion.
2152 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2153 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002154
Georg Brandl3ee81df2008-05-17 18:14:43 +00002155- Issue #1164: It was possible to trigger deadlock when using the
2156 'print' statement to write to a file since the GIL was not released
2157 as needed. Now PyObject_Print() does the right thing along with
2158 various tp_print implementations of the built-in types and those in
2159 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002160
Georg Brandl3ee81df2008-05-17 18:14:43 +00002161- Issue #1147: Exceptions were directly allowing string exceptions in
2162 their throw() method even though string exceptions no longer
2163 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002164
Georg Brandl3ee81df2008-05-17 18:14:43 +00002165- Issue #1096: Prevent a segfault from getting the repr of a very
2166 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002167
Brett Cannon1e534b52007-09-07 04:18:30 +00002168- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002169 PyObject_Call() never calling back out to Python code to trigger
2170 recursion depth updates/checks. Required the creation of a static
2171 RuntimeError instance in case normalizing an exception put the
2172 recursion check value past its limit. Fixes crashers
2173 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002174

Neal Norwitz0ac60192007-05-27 04:08:54 +00002188- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002189 __*__ attributes. (Some already existed, e.g., __doc__ and
2190 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002191
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002192- Add -3 option to the interpreter to warn about features that are
2193 deprecated and will be changed/removed in Python 3.0.
2194
Georg Brandl2134e752007-05-21 20:34:16 +00002195- Patch #1686487: you can now pass any mapping after '**' in function
2196 calls.
2197
Collin Winter62903052007-05-18 23:11:24 +00002198- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002199 "except E as target:". This is to provide forwards compatibility
2200 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002201
Brett Cannon229cee22007-05-05 01:34:02 +00002202- Deprecate BaseException.message as per PEP 352.
2203
Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002205 inherited from a builtin base.
2206
Vinay Sajip8549ce32007-05-06 17:53:37 +00002207- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002208 setting a plain string, ie don't expand to single letter identifiers.
2209
Raymond Hettinger13936692007-04-11 18:40:58 +00002210- Request #1191699: Slices can now be pickled.
2211
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002212- Request #1193128: str.translate() now allows a None argument for
2213 translations that only remove characters without re-mapping the
2214 remaining characters.
2215
Georg Brandl5cb76c12007-03-21 09:00:39 +00002216- Patch #1682205: a TypeError while unpacking an iterable is no longer
2217 masked by a generic one with the message "unpack non-sequence".
2218
Neal Norwitzaa754b72007-03-21 06:39:48 +00002219- Remove unused file Python/fmod.c.
2220
Guido van Rossum143b5642007-03-23 04:58:42 +00002221- Bug #1683368: The object.__init__() and object.__new__() methods are
2222 now stricter in rejecting excess arguments. The only time when
2223 either allows excess arguments is when it is not overridden and the
2224 other one is. For backwards compatibility, when both are
2225 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002226 warning later). Also, type.__init__() insists on the same signature
2227 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002228
Georg Brandl3ee81df2008-05-17 18:14:43 +00002229- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2230 object to complex using its __complex__() method before falling back
2231 to the __float__() method. Therefore, the functions in the cmath
2232 module now can operate on objects that define a __complex__()
2233 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002234
Georg Brandl3ee81df2008-05-17 18:14:43 +00002235- Patch #1623563: allow __class__ assignment for classes with
2236 __slots__. The old and the new class are still required to have the

Georg Brandl3ee81df2008-05-17 18:14:43 +00003307 time so that opening a database previously created with the DB_DUP
3308 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3309 opens. Specifically: dictionary assignment to a DB object will
3310 replace all values for a given key when the database allows
3311 duplicate values. DB users should use DB.put(k, v) when they want
3312 to store duplicates; not DB[k] = v.

3319 characters with ASCII value less than 32. Also, it correctly quotes
3320 dots only if they occur on a single line, as opposed to the previous
3321 behavior of quoting dots if they are the second character of any
3322 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003323
