20 for ints and longs.
21
Mark Dickinson2ffb26f2009-02-15 10:13:41 +000022- Issue #5260: Long integers now consume less memory: average

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

66 an existing .py counterpart, override the co_filename attributes of all
67 code objects if the original filename is obsolete (which can happen if the
68 file has been renamed, moved, or if it is accessed through different paths).
69 Patch by Ziga Seilnacht and Jean-Paul Calderone.
70
Martin v. Löwis5344c992009-01-02 20:32:55 +000071- Issue #4075: Use OutputDebugStringW in Py_FatalError.

104 context manager returns a value that cannot be converted to a bool.
105
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000106- Issue #4597: Fixed several opcodes that weren't always propagating

Mark Dickinson826f3fe2008-12-05 21:55:28 +0000109- Issue #4445: Replace "sizeof(PyStringObject)" with
110 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for

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

Vinay Sajip213faca2008-12-03 23:22:58 +0000124- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000125 method on file objects with closefd=False. The file descriptor is still
126 kept open but the file object behaves like a closed file. The ``FileIO``
127 object also got a new readonly attribute ``closefd``.
128
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000129- Issue #4348: Some bytearray methods returned that didn't cause any change to
130 the bytearray, returned the same bytearray instead of a copy.
131
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000132- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

137
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000138- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
139 exec statement.
140
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000141- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
142 method does not return iterators for the 4th and 5th items.
143
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000144- Issue #4209: Enabling unicode_literals and the print_function in the same
145 __future__ import didn't work.
146
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000147- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000148 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000149
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000150- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
151 returned a path longer than MAX_PATH. (But It's doubtful this code path is
152 really executed because I cannot move to such directory on win2k)
153
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000154- Issue #4069: When set.remove(element) is used with a set element, the element
155 is temporarily replaced with an equivalent frozenset. But the eventual
156 KeyError would always report the empty frozenset([]) as the missing key. Now
157 it correctly refers to the initial element.
158
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000159- Issue #4509: Various issues surrounding resize of bytearray objects to
160 which there are buffer exports.

696
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000697- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
698 PyString_FromFormat or PyErr_Format to display size_t values. The macro
699 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
700 ``printf`` function, whereas PyString_FromFormat has an independent
701 implementation and uses "%zd" on all platforms for size_t values.
702 This makes a difference on win64, where ``printf`` needs "%Id" to display
703 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +0000705- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

709 object; previously an int would be returned for small values. the __long__
710 method is allowed to return either an int or a long, but the behaviour of
711 float objects should not change to respect backward compatibility.
712
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000713- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +0000719 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000720 was correctly parsed but parsing of subsequent arguments failed.
721
Vinay Sajip35e3b032008-09-01 14:33:59 +0000722- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000723 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
724 mechanism. In the process, fix a bug where isinstance() and issubclass(),
725 when given a tuple of classes as second argument, were looking up
726 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
727 type object.
728

738 function 'stringlib_contains_obj'.

872-----------------
873
Guido van Rossumf8402962008-08-20 15:01:50 +0000874- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
875 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
876 extensions do not automatically benefit from the class attribute
877 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
878 to their tp_flags field if they care. This is a backwards
879 compatibility feature; in 3.0, all types will use the cache by
880 default.
881
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000882- Keyword arguments can now follow starred arguments. (``f(a, *args,

Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000898- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
899 (64bit Unix, for example), unichr() would truncate its argument and return
900 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.

905 PyErr_ExceptionMatches returns 0 when an exception occurs there.
906
Antoine Pitrou92f82162008-07-25 22:22:08 +0000907- Issue #1819: function calls with several named parameters are now on
908 average 35% faster (as measured by pybench).
909
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000910- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
911 the python debugger steps into a class statement: the free variables (local
912 variables defined in an outer scope) would be deleted from the outer scope.
913
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000914- Issue #2620: Overflow checking when allocating or reallocating memory
915 was not always being done properly in some python types and extension
916 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
917 all been updated to perform better checks and places in the code that
918 would previously leak memory on the error path when such an allocation
919 failed have been fixed.

928
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000929- Issue #2234: distutils failed for some versions of the cygwin compiler. The
930 version reported by these tools does not necessarily follow the python
931 version numbering scheme, so the module is less strict when parsing it.
932
Nick Coghlanf70385a2008-08-18 12:42:46 +0000933- Issue #2235: Added Py3k warnings for types which will become unhashable
934 under the stricter __hash__ inheritance rules in 3.0. Several types
935 which did not meet the rules for hash invariants and were already
936 unhashable in 3.0 have now been explicitly flagged as unhashable in
937 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
938 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
939

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001035- Issue #3394: zipfile.writestr sets external attributes when passed a
1036 file name rather than a ZipInfo instance, so files are extracted with
1037 mode 0600 rather than 000 under Unix.
1038
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001039- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001051- Issue #2235: the C API function PyObject_HashNotImplemented and its
1052 interaction with the tp_hash slot (added in 2.6b2) are now documented
1053
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001054- Issue #643841: The language reference now provides more detailed
1055 coverage of the lookup process for special methods. The disclaimers
1056 regarding lack of coverage of new-style classes have also been

1061================================
1062
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001063*Release date: 17-Jul-2008*
1064
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001065Core and Builtins
1066-----------------
1067
Georg Brandl3e483f62008-07-16 22:57:41 +00001068- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1069 its methods now allow for items objects that can be converted to
1070 an integer using operator.index().
1071
Mark Dickinson64b7e502008-07-16 09:40:03 +00001072- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1073 produced a ValueError instead of giving the correct float.
1074
Eric Smitha5fa5a22008-07-16 00:11:49 +00001075- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1076 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1077
Mark Dickinson7103aa42008-07-15 19:08:33 +00001078- Issue #3008: the float type has a new instance method 'float.hex'
1079 and a new class method 'float.fromhex' to convert floating-point
1080 numbers to and from hexadecimal strings, respectively.
1081
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001082- Issue #2235: __hash__ is once again inherited by default. To allow
1083 collections.Hashable to remain meaningful in the presence of the
1084 default hash implementation (object.__hash__), it is now possible
1085 to explicit block inheritance of hash by setting __hash__=None at
1086 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1087 level.
1088
Nick Coghlanb028f502008-07-13 14:52:36 +00001089- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1090 the parent module cannot be found while performing an absolute import.
1091 This means that an incorrectly defined __package__ attribute will
1092 now only prevent relative imports in that module rather than causing
1093 all imports from that module to fail.
1094
Nick Coghlan14ff9942008-07-08 14:21:42 +00001095- Issue #2517: Allow unicode messages in Exceptions again by correctly
1096 bypassing the instance dictionary when looking up __unicode__ on
1097 new-style classes.
1098
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001099- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1100 set to a custom object whose write() method happens to install
1101 another file in sys.stdout.
1102
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001103- Issue #3088: Corrected a race condition in classes derived from
1104 threading.local: the first member set by a thread could be saved in
1105 another thread's dictionary.
1106
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001107- Issue #3004: Minor change to slice.indices(): the start and stop
1108 arguments are now treated identically, making the behaviour easier
1109 to describe and understand. For example, slice(None, -10,
1110 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1111 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1112 10, -1).
1113
Georg Brandl278fc502008-07-19 12:46:12 +00001114- Issue #3219: Calling a function with repeated keyword arguments,
1115 f(a=2, a=23), would not cause a syntax error. This was a regression
1116 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001117
Georg Brandl278fc502008-07-19 12:46:12 +00001118- Issue #2862: Make int and float freelist management consistent with
1119 other freelists. Changes their CompactFreeList apis into
1120 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001125- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1126 api functions without holding the GIL, which could lead to a fatal
1127 error when they failed.
1128
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001129- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001152- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001153
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001154- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1155 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001156 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001157 content-length. The problem had been corrected in the 2.4 branch, but never
1158 merged into trunk.
1159
Georg Brandle78fbcc2008-07-05 10:13:36 +00001160- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001173- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1174 handling is now the same as that of other special attributes like __name__).
1175
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001176- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00001566 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001567
1568 This is controlled by the configure argument ``--with-universal-archs``:
1569
1570 - ``--with-universal-archs=all``: install 4-way universal
1571
1572 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1573
1574 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1575
1576 This option should be used in combination with ``--enable-universalsdk=``.
1577
1578 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 +00001628- Issue #1631171: Re-implement the 'warnings' module in C (the
1629 original Python code has been kept as backup). This will allow for
1630 using the 'warning's machinery in such places as the parser where
1631 use of pure Python code is not possible. Both the ``showarning()``
1632 and ``formatwarning()`` gain an optional 'line' argument which is
1633 not called by default for backwards-compatibility reasons. Setting
1634 ``warnings.showwarning()`` to an implementation that lacks support
1635 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001698- Issue #2550: The approach used by client/server code for obtaining
1699 ports to listen on in network-oriented tests has been refined in an
1700 effort to facilitate running multiple instances of the entire
1701 regression test suite in parallel without issue.
1702 test_support.bind_port() has been fixed such that it will always
1703 return a unique port -- which wasn't always the case with the
1704 previous implementation, especially if socket options had been set
1705 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1706 new implementation of bind_port() will actually raise an exception
1707 if it is passed an AF_INET/SOCK_STREAM socket with either the
1708 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1709 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1710 the socket it's been passed. This currently only applies to
1711 Windows. This option prevents any other sockets from binding to the
1712 host/port we've bound to, thus removing the possibility of the
1713 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1714 when a second SOCK_STREAM socket binds and accepts to a host/port
1715 that's already been bound by another socket. The optional preferred
1716 port parameter to bind_port() has been removed. Under no
1717 circumstances should tests be hard coding ports!
1718
1719 test_support.find_unused_port() has also been introduced, which will
1720 pass a temporary socket object to bind_port() in order to obtain an
1721 unused port. The temporary socket object is then closed and
1722 deleted, and the port is returned. This method should only be used
1723 for obtaining an unused port in order to pass to an external program
1724 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1725 a parameter to a server-oriented class that doesn't give you direct
1726 access to the underlying socket used.
1727
1728 Finally, test_support.HOST has been introduced, which should be used
1729 for the host argument of any relevant socket calls (i.e. bind and
1730 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001731
1732 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001733 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

1735 test_asynchat and test_socket_ssl.
1736
Georg Brandl3ee81df2008-05-17 18:14:43 +00001737 It is now possible for multiple instances of the regression test
1738 suite to run in parallel without issue.

2005-----------------
2006
Fred Drakea8ee94b2008-03-01 02:45:07 +00002007- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002008 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002009
Georg Brandlad61bc82008-02-23 15:11:18 +00002010- Issue #2067: file.__exit__() now calls subclasses' close() method.
2011
2012- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002013
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002014- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002015 issue 215555 for a discussion.
2016
Eric Smitha73fbe72008-02-23 03:09:44 +00002017- Added the future_builtins module, which contains hex() and oct().
2018 These are the PEP 3127 version of these functions, designed to be
2019 compatible with the hex() and oct() builtins from Python 3.0. They
2020 differ slightly in their output formats from the existing, unchanged
2021 Python 2.6 builtins. The expected usage of the future_builtins
2022 module is:
2023 from future_builtins import hex, oct
2024
Eric Smith7ef40bf2008-02-20 23:34:22 +00002025- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2026 exponents for exponents with absolute value < 100. Follows C99
2027 standard. This is a change on Windows, which would use 3 digits.
2028 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2029 so that any alterations it does to the resulting string will be
2030 available in stringlib/formatter.h (for float.__format__).
2031
Eric Smith5a3c1352008-02-19 13:21:56 +00002032- Implemented PEP 3101, Advanced String Formatting. This adds a new
2033 builtin format(); a format() method for str and unicode; a
2034 __format__() method to object, str, unicode, int, long, float, and
2035 datetime; the class string.Formatter; and the C API
2036 PyObject_Format().
2037
Georg Brandl3ee81df2008-05-17 18:14:43 +00002038- Fixed several potential crashes, all caused by specially crafted
2039 __del__ methods exploiting objects in temporarily inconsistent
2040 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002041
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002042- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002043 prevent a possible crash: an Abstract Base Class would try to access
2044 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002045
Georg Brandl3ee81df2008-05-17 18:14:43 +00002046- Fixed repr() and str() of complex numbers with infinity or nan as
2047 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002048
Georg Brandl3ee81df2008-05-17 18:14:43 +00002049- Clear all free lists during a gc.collect() of the highest generation
2050 in order to allow pymalloc to free more arenas. Python may give back
2051 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002052
Georg Brandl3ee81df2008-05-17 18:14:43 +00002053- Issue #2045: Fix an infinite recursion triggered when printing a
2054 subclass of collections.defaultdict, if its default_factory is set
2055 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002056
Christian Heimesf75dbef2008-02-08 00:11:31 +00002057- Fixed a minor memory leak in dictobject.c. The content of the free
2058 list was not freed on interpreter shutdown.
2059
Georg Brandl3ee81df2008-05-17 18:14:43 +00002060- Limit free list of method and builtin function objects to 256
2061 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002062
Georg Brandl3ee81df2008-05-17 18:14:43 +00002063- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2064 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002065 to compact the internal free lists of pre-allocted ints and floats.
2066
Georg Brandl3ee81df2008-05-17 18:14:43 +00002067- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2068 calls. Python expected the return type int but the fork familie
2069 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002070
Georg Brandl3ee81df2008-05-17 18:14:43 +00002071- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2072 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002073
Georg Brandl3ee81df2008-05-17 18:14:43 +00002074- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2075 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002076
Georg Brandl3ee81df2008-05-17 18:14:43 +00002077- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2078 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002079
Georg Brandl3ee81df2008-05-17 18:14:43 +00002080- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2081 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002082
Georg Brandl3ee81df2008-05-17 18:14:43 +00002083- Patch #1473257: generator objects gain a gi_code attribute. This is
2084 the same object as the func_code attribute of the function that
2085 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002086
Georg Brandl3ee81df2008-05-17 18:14:43 +00002087- Issue #1920: "while 0" statements were completely removed by the
2088 compiler, even in the presence of an "else" clause, which is
2089 supposed to be run when the condition is false. Now the compiler
2090 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002091
Guido van Rossumeead05f2008-01-24 18:21:02 +00002092- A few crashers fixed: weakref_in_del.py (issue #1377858);
2093 loosing_dict_ref.py (issue #1303614, test67.py);
2094 borrowed_ref_[34].py (not in tracker).
2095
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002096- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002097 suppressed while an extension is loaded by calling SetErrorMode in
2098 dynload_win.c. The error is still reported properly.
2099
Georg Brandl3ee81df2008-05-17 18:14:43 +00002100- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002101 several extension methods and modules do not work without unicode
2102 support.
2103
Georg Brandl26543b12008-01-21 18:36:51 +00002104- Issue #1882: when compiling code from a string, encoding cookies in the
2105 second line of code were not always recognized correctly.
2106
Georg Brandl14404b62008-01-19 19:27:05 +00002107- Issue #1679: "0x" was taken as a valid integer literal.
2108
Georg Brandl6caad7d2008-01-26 14:19:22 +00002109- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002110 added.
2111
Christian Heimesc94e2b52008-01-14 04:13:37 +00002112- sys.float_info / PyFloat_GetInfo: The floating point information
2113 object was converted from a dict to a specialized structseq object.
2114
Georg Brandl3ee81df2008-05-17 18:14:43 +00002115- Patch #1816: Added sys.flags structseq. It exposes the status of
2116 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002117
Georg Brandl3ee81df2008-05-17 18:14:43 +00002118- Objects/structseq.c: Implemented new structseq representation. The
2119 patch makes structseqs (e.g. the return value of os.stat) more
2120 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002121
Georg Brandl3ee81df2008-05-17 18:14:43 +00002122- Patch #1700288: added a type attribute cache that caches method
2123 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002124
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002125- Bug #1776: __import__() no longer accepts filenames on any platform.
2126 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002127
Georg Brandlaed6c662008-01-07 17:25:53 +00002128- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2129
Georg Brandl3ee81df2008-05-17 18:14:43 +00002130- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2131 envvar and sys.dont_write_bytecode attribute. All these can be set
2132 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002133
Georg Brandl3ee81df2008-05-17 18:14:43 +00002134- Improve some exception messages when Windows fails to load an
2135 extension module. Now we get for example '%1 is not a valid Win32
2136 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002137
Georg Brandl3ee81df2008-05-17 18:14:43 +00002138- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002140- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2141 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002142
Christian Heimes0a8143f2007-12-18 23:22:54 +00002143- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002144 and INF. float("nan"), float("inf") and float("-inf") now work on
2145 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002146
Georg Brandl3ee81df2008-05-17 18:14:43 +00002147- Compiler now generates simpler and faster code for dictionary
2148 literals. The oparg for BUILD_MAP now indicates an estimated
2149 dictionary size. There is a new opcode, STORE_MAP, for adding
2150 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002151
Georg Brandl3ee81df2008-05-17 18:14:43 +00002152- Issue #1638: %zd configure test fails on Linux.

2168 running, and if the deallocation of its frames somehow calls the
2169 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002170

2180 file can now be directly executed by passing their name to the
2181 interpreter. The directory/zipfile is automatically inserted as the
2182 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002183
Georg Brandl3ee81df2008-05-17 18:14:43 +00002184- Issue #1265: Fix a problem with sys.settrace, if the tracing
2185 function uses a generator expression when at the same time the
2186 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002187
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002188- sets and frozensets now have an isdisjoint() method.
2189
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002190- optimize the performance of builtin.sum().
2191
Neal Norwitz44f326e2007-10-05 05:29:17 +00002192- Fix warnings found by the new version of the Coverity checker.
2193
Georg Brandl3ee81df2008-05-17 18:14:43 +00002194- The enumerate() builtin function is no longer bounded to sequences
2195 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2196 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002197
Georg Brandl3ee81df2008-05-17 18:14:43 +00002198- Issue #1686386: Tuple's tp_repr did not take into account the
2199 possibility of having a self-referential tuple, which is possible
2200 from C code. Nor did object's tp_str consider that a type's tp_str
2201 could do something that could lead to an inifinite recursion.
2202 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2203 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002204
Georg Brandl3ee81df2008-05-17 18:14:43 +00002205- Issue #1164: It was possible to trigger deadlock when using the
2206 'print' statement to write to a file since the GIL was not released
2207 as needed. Now PyObject_Print() does the right thing along with
2208 various tp_print implementations of the built-in types and those in
2209 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002210
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- Issue #1147: Exceptions were directly allowing string exceptions in
2212 their throw() method even though string exceptions no longer
2213 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002214
Georg Brandl3ee81df2008-05-17 18:14:43 +00002215- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002218- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002219 PyObject_Call() never calling back out to Python code to trigger
2220 recursion depth updates/checks. Required the creation of a static
2221 RuntimeError instance in case normalizing an exception put the
2222 recursion check value past its limit. Fixes crashers
2223 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002224

Neal Norwitz0ac60192007-05-27 04:08:54 +00002238- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002239 __*__ attributes. (Some already existed, e.g., __doc__ and
2240 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002241
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002242- Add -3 option to the interpreter to warn about features that are
2243 deprecated and will be changed/removed in Python 3.0.
2244
Georg Brandl2134e752007-05-21 20:34:16 +00002245- Patch #1686487: you can now pass any mapping after '**' in function
2246 calls.
2247
Collin Winter62903052007-05-18 23:11:24 +00002248- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002249 "except E as target:". This is to provide forwards compatibility
2250 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002251
Brett Cannon229cee22007-05-05 01:34:02 +00002252- Deprecate BaseException.message as per PEP 352.
2253
Georg Brandl3ee81df2008-05-17 18:14:43 +00002254- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002255 inherited from a builtin base.
2256
Vinay Sajip8549ce32007-05-06 17:53:37 +00002257- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002258 setting a plain string, ie don't expand to single letter identifiers.
2259
Raymond Hettinger13936692007-04-11 18:40:58 +00002260- Request #1191699: Slices can now be pickled.
2261
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002262- Request #1193128: str.translate() now allows a None argument for
2263 translations that only remove characters without re-mapping the
2264 remaining characters.
2265
Georg Brandl5cb76c12007-03-21 09:00:39 +00002266- Patch #1682205: a TypeError while unpacking an iterable is no longer
2267 masked by a generic one with the message "unpack non-sequence".
2268

2270
Guido van Rossum143b5642007-03-23 04:58:42 +00002271- Bug #1683368: The object.__init__() and object.__new__() methods are
2272 now stricter in rejecting excess arguments. The only time when
2273 either allows excess arguments is when it is not overridden and the
2274 other one is. For backwards compatibility, when both are
2275 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002276 warning later). Also, type.__init__() insists on the same signature
2277 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002278
Georg Brandl3ee81df2008-05-17 18:14:43 +00002279- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2280 object to complex using its __complex__() method before falling back
2281 to the __float__() method. Therefore, the functions in the cmath
2282 module now can operate on objects that define a __complex__()
2283 method.

2287 same slot names.

2294 its type.

2300
Georg Brandl7b9c5552007-03-12 14:30:05 +00002301- Bug #1678647: write a newline after printing an exception in any
2302 case, even when converting the value to a string failed.
2303
Georg Brandl871f1bc2007-03-12 13:17:36 +00002304- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002305 its argument, if it exists. If not, it will work like before. This
2306 allows customizing the output of dir() in the presence of a
2307 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002308
Collin Winter276887b2007-03-12 16:11:39 +00002309- Patch #922167: Python no longer segfaults when faced with infinitely
2310 self-recursive reload() calls (as reported by bug #742342).
2311
Georg Brandl3ee81df2008-05-17 18:14:43 +00002312- Patch #1675981: remove unreachable code from ``type.__new__()``

2316 parthensized forms. This means complex(repr(x)) now works instead of
2317 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002318
Georg Brandlaa2321b2007-03-07 00:40:28 +00002319- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002320 makes the filenames the warning module prints much more sensible
2321 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002322
Georg Brandl49aafc92007-03-07 00:34:46 +00002323- Variant of patch #697613: don't exit the interpreter on a SystemExit
2324 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002325 variable is given, but break into the interactive interpreter just
2326 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002333
Georg Brandl0fca97a2007-03-05 22:28:08 +00002334- Patch #1674228: when assigning a slice (old-style), check for the
2335 sq_ass_slice instead of the sq_slice slot.
2336
Georg Brandl3ee81df2008-05-17 18:14:43 +00002337- When printing an unraisable error, don't print exceptions. before
2338 the name. This duplicates the behavior whening normally printing
2339 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002340
Georg Brandl3ee81df2008-05-17 18:14:43 +00002341- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002347- Bug #1377858: Fix the segfaulting of the interpreter when an object
2348 created a weakref on itself during a __del__ call for new-style
2349 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002872 AttributeError instead of an IOError when the server's response
2873 didn't contain a valid HTTP status line.

2905
Georg Brandl92a6bae2007-03-13 17:43:32 +00002906- Patch #1603688: ConfigParser.SafeConfigParser now checks values that

Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00002944- Patch #742598: Add .timeout attribute to SocketServer that calls

2964 TestCase and TestSuite subclasses (not instances) are no longer
2965 accepted in TestSuite.addTest(). This should cause no

3247 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003248
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3250 with RFC 3207 and forgets any knowledge obtained from the server not
3251 obtained from the TLS negotiation itself. Patch contributed by Bill
3252 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003255 that the SMTP.starttls() caller no longer needs to call ehlo()
3256 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003257 does not claim to support starttls. Adds the
3258 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3339 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3340 silently miscode subclasses of those types. Now, it raises a
3341 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003342

Georg Brandl3ee81df2008-05-17 18:14:43 +00003357 time so that opening a database previously created with the DB_DUP
3358 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3359 opens. Specifically: dictionary assignment to a DB object will
3360 replace all values for a given key when the database allows
3361 duplicate values. DB users should use DB.put(k, v) when they want
3362 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003363

3369 characters with ASCII value less than 32. Also, it correctly quotes
3370 dots only if they occur on a single line, as opposed to the previous
3371 behavior of quoting dots if they are the second character of any
3372 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003373

3710 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003711
3712- Patch #1720595: add T_BOOL to the range of structmember types.
3713
3714- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3715 ``PyFloat_GetInfo()`` to the float API.
3716
Georg Brandl3ee81df2008-05-17 18:14:43 +00003717- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3718 of w# format code incorrectly truncated the length to an int, even
3719 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3720 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003721
Georg Brandl3ee81df2008-05-17 18:14:43 +00003722- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3723 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003725- PEP 3123: Provide forward compatibility with Python 3.0, while
3726 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3727 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003728
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3730 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003731
3732- Patch #1733960: Allow T_LONGLONG to accept ints.
3733
3734- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3735
Christian Heimes000a0742008-01-03 22:16:32 +00003736- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00003738- Bug #1637022: Prefix AST symbols with _Py_.
3739
3740- Fix some leftovers from the conversion from int to Py_ssize_t
3741 (relevant to strings and sequences of more than 2**31 items).
3742
3743- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3744 outside of pystate.c and should not be necessary.
3745
Georg Brandl3ee81df2008-05-17 18:14:43 +00003746- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3747 absolute imports. In earlier versions they might have used relative
3748 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003749
Georg Brandl3ee81df2008-05-17 18:14:43 +00003750- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3751 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003752
Georg Brandl3ee81df2008-05-17 18:14:43 +00003753- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3754 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003760- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3761 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3762 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3763 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003778- Removed the macfs module. It had been deprecated since Python 2.5.
3779 This lead to the deprecation of macostools.touched() as it relied
3780 solely on macfs and was a no-op under OS X.
