45
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +000046- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
47 collecting the oldest generation) so that allocating lots of objects without
48 destroying them does not show quadratic performance. Based on a proposal by
49 Martin von Löwis at
50 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
51
Martin v. Löwisb90304a2009-01-07 18:40:40 +000052- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.

55 an existing .py counterpart, override the co_filename attributes of all
56 code objects if the original filename is obsolete (which can happen if the
57 file has been renamed, moved, or if it is accessed through different paths).
58 Patch by Ziga Seilnacht and Jean-Paul Calderone.
59
Martin v. Löwis5344c992009-01-02 20:32:55 +000060- Issue #4075: Use OutputDebugStringW in Py_FatalError.
61
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +000062- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
63 file with `str' filename on Windows.

69 where the tp_hash and tp_dict slots are both NULL.
70
Benjamin Peterson7af65562008-12-29 17:56:58 +000071- Issue #4764: With io.open, IOError.filename is set when trying to open a
72 directory on POSIX systems.
73

96 exceptions.
97
Mark Dickinson826f3fe2008-12-05 21:55:28 +000098- Issue #4445: Replace "sizeof(PyStringObject)" with
99 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
100 str instances. On a typical machine this saves 3 bytes of memory
101 (on average) per string allocation.
102
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000103- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
104 interpreter to abort ("Fatal Python error: Could not reset the stack!")
105 instead of throwing a MemoryError.
106
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000107- Issue #3689: The list reversed iterator now supports __length_hint__

112
Vinay Sajip213faca2008-12-03 23:22:58 +0000113- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000114 method on file objects with closefd=False. The file descriptor is still
115 kept open but the file object behaves like a closed file. The ``FileIO``
116 object also got a new readonly attribute ``closefd``.
117
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000118- Issue #4348: Some bytearray methods returned that didn't cause any change to
119 the bytearray, returned the same bytearray instead of a copy.
120
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000121- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
122
Benjamin Peterson273c2332008-11-17 22:39:09 +0000123- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
124
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000125- Issue #4048: The parser module now correctly validates relative imports.
126
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000127- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
128 exec statement.
129
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000130- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
131 method does not return iterators for the 4th and 5th items.
132
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000133- Issue #4209: Enabling unicode_literals and the print_function in the same
134 __future__ import didn't work.
135
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000136- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000137 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000138
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000139- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
140 returned a path longer than MAX_PATH. (But It's doubtful this code path is
141 really executed because I cannot move to such directory on win2k)
142
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000143- Issue #4069: When set.remove(element) is used with a set element, the element
144 is temporarily replaced with an equivalent frozenset. But the eventual
145 KeyError would always report the empty frozenset([]) as the missing key. Now
146 it correctly refers to the initial element.
147
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000148- Issue #4509: Various issues surrounding resize of bytearray objects to
149 which there are buffer exports.
150
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000151- Issue #4748: Lambda generators no longer return a value.
152
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +0000153- Issue #3582: Use native TLS functions on Windows

189 public documented method ``ZipImporter.get_filename()``.
190
Nick Coghland39600e2009-02-08 01:26:34 +0000191- Issue #4195: The ``runpy`` module (and the ``-m`` switch) now support
192 the execution of packages by looking for and executing a ``__main__``
Nick Coghlanc3623b12009-02-08 01:46:01 +0000193 submodule when a package name is supplied. Initial patch by Andi

259 do an explicit seek to the end of file (so that e.g. tell() returns the
260 file size rather than 0). This is consistent with the behaviour of the
261 traditional 2.x file object.
262
Vinay Sajip5fb11b22009-01-20 22:43:17 +0000263- Issue #5013: Fixed a bug in FileHandler which occurred when the delay

267 which inherited from numbers.py which did not have __slots__ defined. The
Mark Dickinson39c6f7f2009-02-12 17:55:42 +0000268 numbers hierarchy now has its own __slots__ declarations.

272 it is possible to segfault the interpreter.
273
Jesse Noller6ab22152009-01-18 02:45:38 +0000274- Issue #4449: AssertionError in mp_benchmarks.py, caused by an underlying issue

292 the timestamp in the gzip stream. The default value remains the current time.
293 The information can be used by e.g. gunzip when decompressing. Patch by
294 Jacques Frechet.
295

603 segfault as a result.
604
Benjamin Peterson8c2b7dc2008-09-18 01:22:16 +0000605- Issue #3886: Possible integer overflows in the _hashopenssl module were

611- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
612 AttributeError instead of RuntimeError, depending in which C API call
613 exactly the recursion limit is exceeded. Consequently, both exception types
614 are caught and silenced.

630
Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000631- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
632
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000633- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
634 PyString_FromFormat or PyErr_Format to display size_t values. The macro
635 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
636 ``printf`` function, whereas PyString_FromFormat has an independent
637 implementation and uses "%zd" on all platforms for size_t values.
638 This makes a difference on win64, where ``printf`` needs "%Id" to display
639 64bit values.
640
Benjamin Peterson97179b02008-09-09 20:55:01 +0000641- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
642 error.
643
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000644- Issue #3777: long() applied to a float object now always return a long
645 object; previously an int would be returned for small values. the __long__
646 method is allowed to return either an int or a long, but the behaviour of
647 float objects should not change to respect backward compatibility.
648
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000649- Issue #3751: str.rpartition would perform a left-partition when called with
650 a unicode argument.
651
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000652- Issue #3683: Fix compilation when --without-threads is given.
653
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000654- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000655 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000656 was correctly parsed but parsing of subsequent arguments failed.
657
Vinay Sajip35e3b032008-09-01 14:33:59 +0000658- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000659 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
660 mechanism. In the process, fix a bug where isinstance() and issubclass(),
661 when given a tuple of classes as second argument, were looking up
662 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
663 type object.
664
Neal Norwitz18aa3882008-08-24 05:04:52 +0000665- Fix crashes on memory allocation failure found with failmalloc.
666
667- Fix memory leaks found with valgrind and update suppressions file.
668
669- Fix compiler warnings in opt mode which would lead to invalid memory reads.
670
671- Fix problem using wrong name in decimal module reported by pychecker.
672
Christian Heimes7d4c3172008-08-22 19:47:25 +0000673- Silenced another compiler warning about a used but not defined
674 function 'stringlib_contains_obj'.
675
Benjamin Peterson712ee922008-08-24 18:10:20 +0000676- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
677 ``__delslice__``.
678
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +0000679- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
680 library targets in the Makefile.
681
Gregory P. Smith980b99b2008-09-07 05:15:18 +0000682- Issue #1204: The configure script now tests for additional libraries
683 that may be required when linking against readline. This fixes issues
684 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

695 stack usage in the case of deeply nested objects.
696

Nick Coghland2e09382008-09-11 12:11:06 +0000701- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
702 silent misbehaviour when a single instance is nested in multiple
703 with statements, or when the methods are invoked in the wrong order.
704
Vinay Sajip844f7412008-09-09 13:42:08 +0000705- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

Brett Cannon32476fc2008-09-05 18:33:51 +0000715
Hirokazu Yamamoto42e459e2008-09-04 14:25:30 +0000716- Issue #3762: platform.architecture() fails if python is lanched via

734 warnings.catch_warnings() along with some API cleanup. Expanding the tests
735 for catch_warnings() also led to an improvement in the raising of a
736 DeprecationWarning related to warnings.warn_explicit().
737
Benjamin Peterson973e6c22008-09-01 23:12:58 +0000738- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000802What's New in Python 2.6 beta 3?
803================================
804
Barry Warsaw07a4a382008-08-21 01:15:08 +0000805*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000806
807Core and Builtins
808-----------------
809
Guido van Rossumf8402962008-08-20 15:01:50 +0000810- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
811 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
812 extensions do not automatically benefit from the class attribute
813 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
814 to their tp_flags field if they care. This is a backwards
815 compatibility feature; in 3.0, all types will use the cache by
816 default.
817
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000818- Keyword arguments can now follow starred arguments. (``f(a, *args,
819 keyword=23)`` is now valid syntax.)
820
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000821- ctypes function pointers that are COM methods have a boolean True
822 value again.
823
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000824- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
825 by denying s# to parse objects that have a releasebuffer procedure,
826 and introducing s*.
827
Georg Brandl1e13ea92008-08-11 09:07:59 +0000828- Issue #3537: Fix an assertion failure when an empty but presized dict
829 object was stored in the freelist.
830
Mark Dickinsonb6467572008-08-04 21:30:09 +0000831- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
832 ValueError consistently across platforms.
833
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000834- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
835 (64bit Unix, for example), unichr() would truncate its argument and return
836 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
837
Neal Norwitze7d8be82008-07-31 17:17:14 +0000838- Apply security patches from Apple.
839
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000840- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
841 PyErr_ExceptionMatches returns 0 when an exception occurs there.
842
Antoine Pitrou92f82162008-07-25 22:22:08 +0000843- Issue #1819: function calls with several named parameters are now on
844 average 35% faster (as measured by pybench).
845
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000846- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
847 the python debugger steps into a class statement: the free variables (local
848 variables defined in an outer scope) would be deleted from the outer scope.
849
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000850- Issue #2620: Overflow checking when allocating or reallocating memory
851 was not always being done properly in some python types and extension
852 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
853 all been updated to perform better checks and places in the code that
854 would previously leak memory on the error path when such an allocation
855 failed have been fixed.

864
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000865- Issue #2234: distutils failed for some versions of the cygwin compiler. The
866 version reported by these tools does not necessarily follow the python
867 version numbering scheme, so the module is less strict when parsing it.
868
Nick Coghlanf70385a2008-08-18 12:42:46 +0000869- Issue #2235: Added Py3k warnings for types which will become unhashable
870 under the stricter __hash__ inheritance rules in 3.0. Several types
871 which did not meet the rules for hash invariants and were already
872 unhashable in 3.0 have now been explicitly flagged as unhashable in
873 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
874 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
875
Brett Cannon88f801d2008-08-18 00:46:22 +0000876- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

884
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000885- Issue #3575: Incremental decoder's decode function now takes bytearray
886 by using 's*' instead of 't#'.
887
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000888- Issue #2222: Fixed reference leak when occured os.rename()
889 fails unicode conversion on 2nd parameter. (windows only)
890
Facundo Batista94f243a2008-08-17 03:38:39 +0000891- Issue 2464. urllib2 now supports a malformation in the URL received
892 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +0000896
Facundo Batistaeb90b782008-08-16 14:44:07 +0000897- Issue #2776: fixed small issue when handling an URL with double slash

1002-----------------
1003
Georg Brandl3e483f62008-07-16 22:57:41 +00001004- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1005 its methods now allow for items objects that can be converted to
1006 an integer using operator.index().
1007
Mark Dickinson64b7e502008-07-16 09:40:03 +00001008- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1009 produced a ValueError instead of giving the correct float.
1010
Eric Smitha5fa5a22008-07-16 00:11:49 +00001011- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1012 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1013
Mark Dickinson7103aa42008-07-15 19:08:33 +00001014- Issue #3008: the float type has a new instance method 'float.hex'
1015 and a new class method 'float.fromhex' to convert floating-point
1016 numbers to and from hexadecimal strings, respectively.
1017
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001018- Issue #2235: __hash__ is once again inherited by default. To allow
1019 collections.Hashable to remain meaningful in the presence of the
1020 default hash implementation (object.__hash__), it is now possible
1021 to explicit block inheritance of hash by setting __hash__=None at
1022 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1023 level.
1024
Nick Coghlanb028f502008-07-13 14:52:36 +00001025- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1026 the parent module cannot be found while performing an absolute import.
1027 This means that an incorrectly defined __package__ attribute will
1028 now only prevent relative imports in that module rather than causing
1029 all imports from that module to fail.
1030
Nick Coghlan14ff9942008-07-08 14:21:42 +00001031- Issue #2517: Allow unicode messages in Exceptions again by correctly
1032 bypassing the instance dictionary when looking up __unicode__ on
1033 new-style classes.

1036 set to a custom object whose write() method happens to install
1037 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001039- Issue #3088: Corrected a race condition in classes derived from
1040 threading.local: the first member set by a thread could be saved in
1041 another thread's dictionary.
1042
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001043- Issue #3004: Minor change to slice.indices(): the start and stop
1044 arguments are now treated identically, making the behaviour easier
1045 to describe and understand. For example, slice(None, -10,
1046 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1047 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1048 10, -1).
1049
Georg Brandl278fc502008-07-19 12:46:12 +00001050- Issue #3219: Calling a function with repeated keyword arguments,
1051 f(a=2, a=23), would not cause a syntax error. This was a regression
1052 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001053
Georg Brandl278fc502008-07-19 12:46:12 +00001054- Issue #2862: Make int and float freelist management consistent with
1055 other freelists. Changes their CompactFreeList apis into
1056 ClearFreeList apis and calls them via gc.collect().

1062 api functions without holding the GIL, which could lead to a fatal
1063 error when they failed.
1064
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001065- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001090- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1091 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001092 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001093 content-length. The problem had been corrected in the 2.4 branch, but never
1094 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001109- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1110 handling is now the same as that of other special attributes like __name__).
1111
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001112- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Benjamin Peterson23681932008-05-12 21:42:13 +00001479
Vinay Sajip9828b7e2008-06-17 11:04:02 +00001480- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001481 environment to control the '-arch' flags that are used to build
1482 an extension. This was added for compatibility with Apple's build
1483 of Python.
1484
1485- The bundled OSX-specific copy of libbffi is now in sync with the version
1486 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
1487
Georg Brandl25c34082008-08-18 23:09:49 +00001488- The threading module gained aliases for names that will be removed in the

Brett Cannonb61d8012008-05-11 23:39:04 +00001498- ``Lib/lib-old`` is now added to sys.path.
1499
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001500- On MacOS X it is now possible to install the framework in 64-bit
1501 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001502 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001503
1504 This is controlled by the configure argument ``--with-universal-archs``:
1505
1506 - ``--with-universal-archs=all``: install 4-way universal
1507
1508 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1509
1510 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1511
1512 This option should be used in combination with ``--enable-universalsdk=``.
1513
1514 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 +00001564- Issue #1631171: Re-implement the 'warnings' module in C (the
1565 original Python code has been kept as backup). This will allow for
1566 using the 'warning's machinery in such places as the parser where
1567 use of pure Python code is not possible. Both the ``showarning()``
1568 and ``formatwarning()`` gain an optional 'line' argument which is
1569 not called by default for backwards-compatibility reasons. Setting
1570 ``warnings.showwarning()`` to an implementation that lacks support
1571 for the ``line`` argument will raise a DeprecationWarning.

1595
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001596- The getpass module has been improved on Unix. It now uses /dev/tty
1597 by default and uses stderr instead of stdout. A GetPassWarning is
1598 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00001599

Georg Brandl3ee81df2008-05-17 18:14:43 +00001613- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001614 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001634- Issue #2550: The approach used by client/server code for obtaining
1635 ports to listen on in network-oriented tests has been refined in an
1636 effort to facilitate running multiple instances of the entire
1637 regression test suite in parallel without issue.
1638 test_support.bind_port() has been fixed such that it will always
1639 return a unique port -- which wasn't always the case with the
1640 previous implementation, especially if socket options had been set
1641 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1642 new implementation of bind_port() will actually raise an exception
1643 if it is passed an AF_INET/SOCK_STREAM socket with either the
1644 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1645 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1646 the socket it's been passed. This currently only applies to
1647 Windows. This option prevents any other sockets from binding to the
1648 host/port we've bound to, thus removing the possibility of the
1649 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1650 when a second SOCK_STREAM socket binds and accepts to a host/port
1651 that's already been bound by another socket. The optional preferred
1652 port parameter to bind_port() has been removed. Under no
1653 circumstances should tests be hard coding ports!
1654
1655 test_support.find_unused_port() has also been introduced, which will
1656 pass a temporary socket object to bind_port() in order to obtain an
1657 unused port. The temporary socket object is then closed and
1658 deleted, and the port is returned. This method should only be used
1659 for obtaining an unused port in order to pass to an external program
1660 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1661 a parameter to a server-oriented class that doesn't give you direct
1662 access to the underlying socket used.
1663
1664 Finally, test_support.HOST has been introduced, which should be used
1665 for the host argument of any relevant socket calls (i.e. bind and
1666 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001667
1668 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001669 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001670 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1671 test_asynchat and test_socket_ssl.
1672
Georg Brandl3ee81df2008-05-17 18:14:43 +00001673 It is now possible for multiple instances of the regression test
1674 suite to run in parallel without issue.

1941-----------------
1942
Fred Drakea8ee94b2008-03-01 02:45:07 +00001943- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001944 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00001949
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001950- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001951 issue 215555 for a discussion.
1952
Eric Smitha73fbe72008-02-23 03:09:44 +00001953- Added the future_builtins module, which contains hex() and oct().
1954 These are the PEP 3127 version of these functions, designed to be
1955 compatible with the hex() and oct() builtins from Python 3.0. They
1956 differ slightly in their output formats from the existing, unchanged
1957 Python 2.6 builtins. The expected usage of the future_builtins
1958 module is:
1959 from future_builtins import hex, oct
1960
Eric Smith7ef40bf2008-02-20 23:34:22 +00001961- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1962 exponents for exponents with absolute value < 100. Follows C99
1963 standard. This is a change on Windows, which would use 3 digits.
1964 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1965 so that any alterations it does to the resulting string will be
1966 available in stringlib/formatter.h (for float.__format__).
1967
Eric Smith5a3c1352008-02-19 13:21:56 +00001968- Implemented PEP 3101, Advanced String Formatting. This adds a new
1969 builtin format(); a format() method for str and unicode; a
1970 __format__() method to object, str, unicode, int, long, float, and
1971 datetime; the class string.Formatter; and the C API
1972 PyObject_Format().
1973
Georg Brandl3ee81df2008-05-17 18:14:43 +00001974- Fixed several potential crashes, all caused by specially crafted
1975 __del__ methods exploiting objects in temporarily inconsistent
1976 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001977
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001978- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001979 prevent a possible crash: an Abstract Base Class would try to access
1980 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001981

1983 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001985- Clear all free lists during a gc.collect() of the highest generation
1986 in order to allow pymalloc to free more arenas. Python may give back
1987 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001988
Georg Brandl3ee81df2008-05-17 18:14:43 +00001989- Issue #2045: Fix an infinite recursion triggered when printing a
1990 subclass of collections.defaultdict, if its default_factory is set
1991 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001992
Christian Heimesf75dbef2008-02-08 00:11:31 +00001993- Fixed a minor memory leak in dictobject.c. The content of the free
1994 list was not freed on interpreter shutdown.
1995
Georg Brandl3ee81df2008-05-17 18:14:43 +00001996- Limit free list of method and builtin function objects to 256
1997 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001998
Georg Brandl3ee81df2008-05-17 18:14:43 +00001999- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2000 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002001 to compact the internal free lists of pre-allocted ints and floats.
2002
Georg Brandl3ee81df2008-05-17 18:14:43 +00002003- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2004 calls. Python expected the return type int but the fork familie
2005 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002006
Georg Brandl3ee81df2008-05-17 18:14:43 +00002007- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2008 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002009
Georg Brandl3ee81df2008-05-17 18:14:43 +00002010- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2011 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002012
Georg Brandl3ee81df2008-05-17 18:14:43 +00002013- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002016- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2017 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002018
Georg Brandl3ee81df2008-05-17 18:14:43 +00002019- Patch #1473257: generator objects gain a gi_code attribute. This is
2020 the same object as the func_code attribute of the function that
2021 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002022
Georg Brandl3ee81df2008-05-17 18:14:43 +00002023- Issue #1920: "while 0" statements were completely removed by the
2024 compiler, even in the presence of an "else" clause, which is
2025 supposed to be run when the condition is false. Now the compiler
2026 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002027
Guido van Rossumeead05f2008-01-24 18:21:02 +00002028- A few crashers fixed: weakref_in_del.py (issue #1377858);
2029 loosing_dict_ref.py (issue #1303614, test67.py);
2030 borrowed_ref_[34].py (not in tracker).
2031
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002032- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002033 suppressed while an extension is loaded by calling SetErrorMode in
2034 dynload_win.c. The error is still reported properly.
2035
Georg Brandl3ee81df2008-05-17 18:14:43 +00002036- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002037 several extension methods and modules do not work without unicode
2038 support.
2039
Georg Brandl26543b12008-01-21 18:36:51 +00002040- Issue #1882: when compiling code from a string, encoding cookies in the
2041 second line of code were not always recognized correctly.
2042
Georg Brandl14404b62008-01-19 19:27:05 +00002043- Issue #1679: "0x" was taken as a valid integer literal.
2044
Georg Brandl6caad7d2008-01-26 14:19:22 +00002045- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002046 added.
2047
Christian Heimesc94e2b52008-01-14 04:13:37 +00002048- sys.float_info / PyFloat_GetInfo: The floating point information
2049 object was converted from a dict to a specialized structseq object.
2050
Georg Brandl3ee81df2008-05-17 18:14:43 +00002051- Patch #1816: Added sys.flags structseq. It exposes the status of
2052 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002053
Georg Brandl3ee81df2008-05-17 18:14:43 +00002054- Objects/structseq.c: Implemented new structseq representation. The
2055 patch makes structseqs (e.g. the return value of os.stat) more
2056 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002057
Georg Brandl3ee81df2008-05-17 18:14:43 +00002058- Patch #1700288: added a type attribute cache that caches method
2059 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002060
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002061- Bug #1776: __import__() no longer accepts filenames on any platform.
2062 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002063
Georg Brandlaed6c662008-01-07 17:25:53 +00002064- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2065
Georg Brandl3ee81df2008-05-17 18:14:43 +00002066- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2067 envvar and sys.dont_write_bytecode attribute. All these can be set
2068 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002069
Georg Brandl3ee81df2008-05-17 18:14:43 +00002070- Improve some exception messages when Windows fails to load an
2071 extension module. Now we get for example '%1 is not a valid Win32
2072 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002073

2077 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002078
Christian Heimes0a8143f2007-12-18 23:22:54 +00002079- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002080 and INF. float("nan"), float("inf") and float("-inf") now work on
2081 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002082
Georg Brandl3ee81df2008-05-17 18:14:43 +00002083- Compiler now generates simpler and faster code for dictionary
2084 literals. The oparg for BUILD_MAP now indicates an estimated
2085 dictionary size. There is a new opcode, STORE_MAP, for adding
2086 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002087

Georg Brandl3ee81df2008-05-17 18:14:43 +00002115- Patch #1739468: Directories and zipfiles containing a __main__.py
2116 file can now be directly executed by passing their name to the
2117 interpreter. The directory/zipfile is automatically inserted as the
2118 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002119
Georg Brandl3ee81df2008-05-17 18:14:43 +00002120- Issue #1265: Fix a problem with sys.settrace, if the tracing
2121 function uses a generator expression when at the same time the
2122 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002123
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002124- sets and frozensets now have an isdisjoint() method.
2125

2127
Neal Norwitz44f326e2007-10-05 05:29:17 +00002128- Fix warnings found by the new version of the Coverity checker.
2129
Georg Brandl3ee81df2008-05-17 18:14:43 +00002130- The enumerate() builtin function is no longer bounded to sequences
2131 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2132 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002133
Georg Brandl3ee81df2008-05-17 18:14:43 +00002134- Issue #1686386: Tuple's tp_repr did not take into account the
2135 possibility of having a self-referential tuple, which is possible
2136 from C code. Nor did object's tp_str consider that a type's tp_str
2137 could do something that could lead to an inifinite recursion.
2138 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2139 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002140
Georg Brandl3ee81df2008-05-17 18:14:43 +00002141- Issue #1164: It was possible to trigger deadlock when using the
2142 'print' statement to write to a file since the GIL was not released
2143 as needed. Now PyObject_Print() does the right thing along with
2144 various tp_print implementations of the built-in types and those in
2145 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002146
Georg Brandl3ee81df2008-05-17 18:14:43 +00002147- Issue #1147: Exceptions were directly allowing string exceptions in
2148 their throw() method even though string exceptions no longer
2149 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002150
Georg Brandl3ee81df2008-05-17 18:14:43 +00002151- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002153
Brett Cannon1e534b52007-09-07 04:18:30 +00002154- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002155 PyObject_Call() never calling back out to Python code to trigger
2156 recursion depth updates/checks. Required the creation of a static
2157 RuntimeError instance in case normalizing an exception put the
2158 recursion check value past its limit. Fixes crashers
2159 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002160

Neal Norwitz0ac60192007-05-27 04:08:54 +00002174- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002175 __*__ attributes. (Some already existed, e.g., __doc__ and
2176 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002177
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002178- Add -3 option to the interpreter to warn about features that are
2179 deprecated and will be changed/removed in Python 3.0.
2180
Georg Brandl2134e752007-05-21 20:34:16 +00002181- Patch #1686487: you can now pass any mapping after '**' in function
2182 calls.
2183
Collin Winter62903052007-05-18 23:11:24 +00002184- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002185 "except E as target:". This is to provide forwards compatibility
2186 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002187
Brett Cannon229cee22007-05-05 01:34:02 +00002188- Deprecate BaseException.message as per PEP 352.
2189
Georg Brandl3ee81df2008-05-17 18:14:43 +00002190- Issue #1303614: don't expose object's __dict__ when the dict is

2192
Vinay Sajip8549ce32007-05-06 17:53:37 +00002193- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002194 setting a plain string, ie don't expand to single letter identifiers.
2195
Raymond Hettinger13936692007-04-11 18:40:58 +00002196- Request #1191699: Slices can now be pickled.
2197
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002198- Request #1193128: str.translate() now allows a None argument for
2199 translations that only remove characters without re-mapping the
2200 remaining characters.
2201
Georg Brandl5cb76c12007-03-21 09:00:39 +00002202- Patch #1682205: a TypeError while unpacking an iterable is no longer
2203 masked by a generic one with the message "unpack non-sequence".
2204
Neal Norwitzaa754b72007-03-21 06:39:48 +00002205- Remove unused file Python/fmod.c.
2206
Guido van Rossum143b5642007-03-23 04:58:42 +00002207- Bug #1683368: The object.__init__() and object.__new__() methods are
2208 now stricter in rejecting excess arguments. The only time when
2209 either allows excess arguments is when it is not overridden and the
2210 other one is. For backwards compatibility, when both are
2211 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002212 warning later). Also, type.__init__() insists on the same signature
2213 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002214
Georg Brandl3ee81df2008-05-17 18:14:43 +00002215- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2216 object to complex using its __complex__() method before falling back
2217 to the __float__() method. Therefore, the functions in the cmath
2218 module now can operate on objects that define a __complex__()
2219 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002220
Georg Brandl3ee81df2008-05-17 18:14:43 +00002221- Patch #1623563: allow __class__ assignment for classes with
2222 __slots__. The old and the new class are still required to have the
2223 same slot names.

2239
Georg Brandl871f1bc2007-03-12 13:17:36 +00002240- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002241 its argument, if it exists. If not, it will work like before. This
2242 allows customizing the output of dir() in the presence of a
2243 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002255- Patch #703779: unset __file__ in __main__ after running a file. This

2326 embedded in the string to convert.
2327

Georg Brandl3ee81df2008-05-17 18:14:43 +00002767 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002808 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00003293 time so that opening a database previously created with the DB_DUP
3294 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3295 opens. Specifically: dictionary assignment to a DB object will
3296 replace all values for a given key when the database allows
3297 duplicate values. DB users should use DB.put(k, v) when they want
3298 to store duplicates; not DB[k] = v.

3305 characters with ASCII value less than 32. Also, it correctly quotes
3306 dots only if they occur on a single line, as opposed to the previous
3307 behavior of quoting dots if they are the second character of any
3308 line.
