31
Antoine Pitrouc2f02212009-01-13 23:13:52 +000032- Issue #4935: The overflow checking code in the expandtabs() method common
33 to str, bytes and bytearray could be optimized away by the compiler, letting
34 the interpreter segfault instead of raising an error.
35
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +000036- Issue #3720: Fix a crash when an iterator modifies its class and removes its

44 collecting the oldest generation) so that allocating lots of objects without
45 destroying them does not show quadratic performance. Based on a proposal by
46 Martin von Löwis at
47 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
48
Martin v. Löwisb90304a2009-01-07 18:40:40 +000049- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.

52 an existing .py counterpart, override the co_filename attributes of all
53 code objects if the original filename is obsolete (which can happen if the
54 file has been renamed, moved, or if it is accessed through different paths).
55 Patch by Ziga Seilnacht and Jean-Paul Calderone.
56
Martin v. Löwis5344c992009-01-02 20:32:55 +000057- Issue #4075: Use OutputDebugStringW in Py_FatalError.

90 context manager returns a value that cannot be converted to a bool.
91
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +000092- Issue #4597: Fixed several opcodes that weren't always propagating

Mark Dickinson826f3fe2008-12-05 21:55:28 +000095- Issue #4445: Replace "sizeof(PyStringObject)" with
96 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
97 str instances. On a typical machine this saves 3 bytes of memory
98 (on average) per string allocation.
99
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000100- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
101 interpreter to abort ("Fatal Python error: Could not reset the stack!")
102 instead of throwing a MemoryError.
103
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000104- Issue #3689: The list reversed iterator now supports __length_hint__
105 instead of __len__. Behavior now matches other reversed iterators.
106
Benjamin Petersonc078f922008-11-21 22:27:24 +0000107- Issue #4367: Python would segfault during compiling when the unicodedata

Vinay Sajip213faca2008-12-03 23:22:58 +0000110- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000111 method on file objects with closefd=False. The file descriptor is still
112 kept open but the file object behaves like a closed file. The ``FileIO``
113 object also got a new readonly attribute ``closefd``.
114
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000115- Issue #4348: Some bytearray methods returned that didn't cause any change to

123
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000124- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
125 exec statement.
126
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000127- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
128 method does not return iterators for the 4th and 5th items.
129
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000130- Issue #4209: Enabling unicode_literals and the print_function in the same
131 __future__ import didn't work.
132
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000133- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000134 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000135
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000136- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
137 returned a path longer than MAX_PATH. (But It's doubtful this code path is
138 really executed because I cannot move to such directory on win2k)
139
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000140- Issue #4069: When set.remove(element) is used with a set element, the element
141 is temporarily replaced with an equivalent frozenset. But the eventual
142 KeyError would always report the empty frozenset([]) as the missing key. Now
143 it correctly refers to the initial element.
144
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000145- Issue #4509: Various issues surrounding resize of bytearray objects to
146 which there are buffer exports.
147
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000148- Issue #4748: Lambda generators no longer return a value.
149

171 the execution of packages by looking for and executing a ``__main__``
Nick Coghlanc3623b12009-02-08 01:46:01 +0000172 submodule when a package name is supplied. Initial patch by Andi
173 Vajda.

Jesse Nollerf6da8d12009-01-23 14:04:41 +0000231 --without-threads argument. When this occurs, _multiprocessing will
232 be disabled, and not compiled.
233
Antoine Pitroue741cc62009-01-21 00:45:36 +0000234- Issue #5008: When a file is opened in append mode with the new IO library,
235 do an explicit seek to the end of file (so that e.g. tell() returns the
236 file size rather than 0). This is consistent with the behaviour of the
237 traditional 2.x file object.
238
Vinay Sajip5fb11b22009-01-20 22:43:17 +0000239- Issue #5013: Fixed a bug in FileHandler which occurred when the delay

604 implementation and uses "%zd" on all platforms for size_t values.
605 This makes a difference on win64, where ``printf`` needs "%Id" to display
606 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +0000608- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
609 error.
610
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000611- Issue #3777: long() applied to a float object now always return a long
612 object; previously an int would be returned for small values. the __long__
613 method is allowed to return either an int or a long, but the behaviour of
614 float objects should not change to respect backward compatibility.
615
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000616- Issue #3751: str.rpartition would perform a left-partition when called with
617 a unicode argument.
618

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000621- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000622 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000623 was correctly parsed but parsing of subsequent arguments failed.
624
Vinay Sajip35e3b032008-09-01 14:33:59 +0000625- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000626 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
627 mechanism. In the process, fix a bug where isinstance() and issubclass(),
628 when given a tuple of classes as second argument, were looking up
629 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
630 type object.
631
Neal Norwitz18aa3882008-08-24 05:04:52 +0000632- Fix crashes on memory allocation failure found with failmalloc.

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

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000769What's New in Python 2.6 beta 3?
770================================
771
Barry Warsaw07a4a382008-08-21 01:15:08 +0000772*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000773
774Core and Builtins
775-----------------
776
Guido van Rossumf8402962008-08-20 15:01:50 +0000777- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
778 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
779 extensions do not automatically benefit from the class attribute
780 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
781 to their tp_flags field if they care. This is a backwards
782 compatibility feature; in 3.0, all types will use the cache by
783 default.
784
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000785- Keyword arguments can now follow starred arguments. (``f(a, *args,
786 keyword=23)`` is now valid syntax.)
787
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000788- ctypes function pointers that are COM methods have a boolean True
789 value again.
790
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000791- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
792 by denying s# to parse objects that have a releasebuffer procedure,
793 and introducing s*.
794
Georg Brandl1e13ea92008-08-11 09:07:59 +0000795- Issue #3537: Fix an assertion failure when an empty but presized dict
796 object was stored in the freelist.
797
Mark Dickinsonb6467572008-08-04 21:30:09 +0000798- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
799 ValueError consistently across platforms.
800
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000801- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
802 (64bit Unix, for example), unichr() would truncate its argument and return
803 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
804
Neal Norwitze7d8be82008-07-31 17:17:14 +0000805- Apply security patches from Apple.
806
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000807- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
808 PyErr_ExceptionMatches returns 0 when an exception occurs there.
809
Antoine Pitrou92f82162008-07-25 22:22:08 +0000810- Issue #1819: function calls with several named parameters are now on
811 average 35% faster (as measured by pybench).
812
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000813- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
814 the python debugger steps into a class statement: the free variables (local
815 variables defined in an outer scope) would be deleted from the outer scope.
816
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000817- Issue #2620: Overflow checking when allocating or reallocating memory
818 was not always being done properly in some python types and extension
819 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
820 all been updated to perform better checks and places in the code that
821 would previously leak memory on the error path when such an allocation
822 failed have been fixed.

831
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000832- Issue #2234: distutils failed for some versions of the cygwin compiler. The
833 version reported by these tools does not necessarily follow the python
834 version numbering scheme, so the module is less strict when parsing it.
835
Nick Coghlanf70385a2008-08-18 12:42:46 +0000836- Issue #2235: Added Py3k warnings for types which will become unhashable
837 under the stricter __hash__ inheritance rules in 3.0. Several types
838 which did not meet the rules for hash invariants and were already
839 unhashable in 3.0 have now been explicitly flagged as unhashable in
840 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
841 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
842
Brett Cannon88f801d2008-08-18 00:46:22 +0000843- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

851
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000852- Issue #3575: Incremental decoder's decode function now takes bytearray
853 by using 's*' instead of 't#'.
854
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000855- Issue #2222: Fixed reference leak when occured os.rename()
856 fails unicode conversion on 2nd parameter. (windows only)
857
Facundo Batista94f243a2008-08-17 03:38:39 +0000858- Issue 2464. urllib2 now supports a malformation in the URL received
859 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +0000863
Facundo Batistaeb90b782008-08-16 14:44:07 +0000864- Issue #2776: fixed small issue when handling an URL with double slash
865 after a 302 response in the case of not going through a proxy.
866
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000867- Issue #2676: in the email package, content-type parsing was hanging on
868 pathological input because of quadratic or exponential behaviour of a
869 regular expression.
870
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000871- Issue #3476: binary buffered reading through the new "io" library is now
872 thread-safe.
873
Brett Cannonbf3157b2008-08-14 05:00:03 +0000874- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
875 since mimetools itself is deprecated. Because modules are cached, all
876 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
877
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000878- Issue #3134: shutil referenced undefined WindowsError symbol.

881 menu entries were not deleted.
882
Brett Cannon83e81842008-08-09 23:30:55 +0000883- Copied the implementation of reduce() to _functools.reduce() to have a
884 version that did not raise a DeprecationWarning under -3.
885
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000886- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
887 a MemoryError rather than silently stop the iteration.
888
Guido van Rossum59ce9012008-08-09 14:55:34 +0000889- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
890 to _sre.compile() will now be rejected. This should not affect anybody
891 since the re.compile() function never generates invalid re-bytecode.
892
Skip Montanaroa032bf42008-08-08 22:52:51 +0000893- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
894 upon first access it can be automatically initialized from the csv file if
895 it wasn't initialized during instantiation.
896
Brett Cannon3aa2a492008-08-06 22:28:09 +0000897- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
898 the reload() built-in has been removed.
899

Antoine Pitroude781a42008-08-09 12:43:23 +0000912 asking for a specific length. This problem only affected files opened

969-----------------
970
Georg Brandl3e483f62008-07-16 22:57:41 +0000971- Issue #3156: Fix inconsistent behavior of the bytearray type: all
972 its methods now allow for items objects that can be converted to
973 an integer using operator.index().
974
Mark Dickinson64b7e502008-07-16 09:40:03 +0000975- Issue #3360: Fix incorrect parsing of '020000000000.0', which
976 produced a ValueError instead of giving the correct float.
977
Eric Smitha5fa5a22008-07-16 00:11:49 +0000978- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
979 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
980
Mark Dickinson7103aa42008-07-15 19:08:33 +0000981- Issue #3008: the float type has a new instance method 'float.hex'
982 and a new class method 'float.fromhex' to convert floating-point
983 numbers to and from hexadecimal strings, respectively.
984
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000985- Issue #2235: __hash__ is once again inherited by default. To allow
986 collections.Hashable to remain meaningful in the presence of the
987 default hash implementation (object.__hash__), it is now possible
988 to explicit block inheritance of hash by setting __hash__=None at
989 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
990 level.
991
Nick Coghlanb028f502008-07-13 14:52:36 +0000992- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
993 the parent module cannot be found while performing an absolute import.
994 This means that an incorrectly defined __package__ attribute will
995 now only prevent relative imports in that module rather than causing
996 all imports from that module to fail.
997
Nick Coghlan14ff9942008-07-08 14:21:42 +0000998- Issue #2517: Allow unicode messages in Exceptions again by correctly

1008 another thread's dictionary.
1009
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001010- Issue #3004: Minor change to slice.indices(): the start and stop
1011 arguments are now treated identically, making the behaviour easier
1012 to describe and understand. For example, slice(None, -10,
1013 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1014 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1015 10, -1).
1016
Georg Brandl278fc502008-07-19 12:46:12 +00001017- Issue #3219: Calling a function with repeated keyword arguments,
1018 f(a=2, a=23), would not cause a syntax error. This was a regression
1019 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001020

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001057- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1058 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001059 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001060 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001076- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1486
Georg Brandl74a1dea2008-05-28 11:21:39 +00001487- Add ``PyType_Modified()`` as a public API to clear the type cache.
1488
1489- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00001490
1491- The PyString functions have been renamed to PyBytes. A batch of
1492 defines were added so that the linker still sees the original
1493 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001531- Issue #1631171: Re-implement the 'warnings' module in C (the
1532 original Python code has been kept as backup). This will allow for
1533 using the 'warning's machinery in such places as the parser where
1534 use of pure Python code is not possible. Both the ``showarning()``
1535 and ``formatwarning()`` gain an optional 'line' argument which is
1536 not called by default for backwards-compatibility reasons. Setting
1537 ``warnings.showwarning()`` to an implementation that lacks support
1538 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001563- The getpass module has been improved on Unix. It now uses /dev/tty
1564 by default and uses stderr instead of stdout. A GetPassWarning is
1565 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001580- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001581 extension modules between 32 and 64 bit platforms. See the distutls
1582 build documentation for more information.

1594 so the controlled environment will more closely mirror the typical
1595 script environment. This supports setup.py scripts that refer to
1596 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001601- Issue #2550: The approach used by client/server code for obtaining
1602 ports to listen on in network-oriented tests has been refined in an
1603 effort to facilitate running multiple instances of the entire
1604 regression test suite in parallel without issue.
1605 test_support.bind_port() has been fixed such that it will always
1606 return a unique port -- which wasn't always the case with the
1607 previous implementation, especially if socket options had been set
1608 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1609 new implementation of bind_port() will actually raise an exception
1610 if it is passed an AF_INET/SOCK_STREAM socket with either the
1611 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1612 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1613 the socket it's been passed. This currently only applies to
1614 Windows. This option prevents any other sockets from binding to the
1615 host/port we've bound to, thus removing the possibility of the
1616 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1617 when a second SOCK_STREAM socket binds and accepts to a host/port
1618 that's already been bound by another socket. The optional preferred
1619 port parameter to bind_port() has been removed. Under no
1620 circumstances should tests be hard coding ports!
1621
1622 test_support.find_unused_port() has also been introduced, which will
1623 pass a temporary socket object to bind_port() in order to obtain an
1624 unused port. The temporary socket object is then closed and
1625 deleted, and the port is returned. This method should only be used
1626 for obtaining an unused port in order to pass to an external program
1627 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1628 a parameter to a server-oriented class that doesn't give you direct
1629 access to the underlying socket used.
1630
1631 Finally, test_support.HOST has been introduced, which should be used
1632 for the host argument of any relevant socket calls (i.e. bind and
1633 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001634
1635 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001636 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001637 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1638 test_asynchat and test_socket_ssl.
1639
Georg Brandl3ee81df2008-05-17 18:14:43 +00001640 It is now possible for multiple instances of the regression test
1641 suite to run in parallel without issue.

1908-----------------
1909
Fred Drakea8ee94b2008-03-01 02:45:07 +00001910- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001911 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001912
Georg Brandlad61bc82008-02-23 15:11:18 +00001913- Issue #2067: file.__exit__() now calls subclasses' close() method.
1914
1915- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001916
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001917- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001918 issue 215555 for a discussion.
1919
Eric Smitha73fbe72008-02-23 03:09:44 +00001920- Added the future_builtins module, which contains hex() and oct().
1921 These are the PEP 3127 version of these functions, designed to be
1922 compatible with the hex() and oct() builtins from Python 3.0. They
1923 differ slightly in their output formats from the existing, unchanged
1924 Python 2.6 builtins. The expected usage of the future_builtins
1925 module is:
1926 from future_builtins import hex, oct
1927
Eric Smith7ef40bf2008-02-20 23:34:22 +00001928- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1929 exponents for exponents with absolute value < 100. Follows C99
1930 standard. This is a change on Windows, which would use 3 digits.
1931 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1932 so that any alterations it does to the resulting string will be
1933 available in stringlib/formatter.h (for float.__format__).
1934
Eric Smith5a3c1352008-02-19 13:21:56 +00001935- Implemented PEP 3101, Advanced String Formatting. This adds a new
1936 builtin format(); a format() method for str and unicode; a
1937 __format__() method to object, str, unicode, int, long, float, and
1938 datetime; the class string.Formatter; and the C API
1939 PyObject_Format().
1940
Georg Brandl3ee81df2008-05-17 18:14:43 +00001941- Fixed several potential crashes, all caused by specially crafted
1942 __del__ methods exploiting objects in temporarily inconsistent
1943 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001944
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001945- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001946 prevent a possible crash: an Abstract Base Class would try to access
1947 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001948

Georg Brandl3ee81df2008-05-17 18:14:43 +00001952- Clear all free lists during a gc.collect() of the highest generation
1953 in order to allow pymalloc to free more arenas. Python may give back
1954 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001955
Georg Brandl3ee81df2008-05-17 18:14:43 +00001956- Issue #2045: Fix an infinite recursion triggered when printing a
1957 subclass of collections.defaultdict, if its default_factory is set
1958 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001959
Christian Heimesf75dbef2008-02-08 00:11:31 +00001960- Fixed a minor memory leak in dictobject.c. The content of the free
1961 list was not freed on interpreter shutdown.
1962
Georg Brandl3ee81df2008-05-17 18:14:43 +00001963- Limit free list of method and builtin function objects to 256
1964 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001966- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1967 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001968 to compact the internal free lists of pre-allocted ints and floats.
1969
Georg Brandl3ee81df2008-05-17 18:14:43 +00001970- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1971 calls. Python expected the return type int but the fork familie
1972 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001973
Georg Brandl3ee81df2008-05-17 18:14:43 +00001974- Issue #1678380: Fix a bug that identifies 0j and -0j when they

1984 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001985
Georg Brandl3ee81df2008-05-17 18:14:43 +00001986- Patch #1473257: generator objects gain a gi_code attribute. This is
1987 the same object as the func_code attribute of the function that
1988 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001989
Georg Brandl3ee81df2008-05-17 18:14:43 +00001990- Issue #1920: "while 0" statements were completely removed by the
1991 compiler, even in the presence of an "else" clause, which is
1992 supposed to be run when the condition is false. Now the compiler

Guido van Rossumeead05f2008-01-24 18:21:02 +00001995- A few crashers fixed: weakref_in_del.py (issue #1377858);
1996 loosing_dict_ref.py (issue #1303614, test67.py);
1997 borrowed_ref_[34].py (not in tracker).
1998
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001999- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002000 suppressed while an extension is loaded by calling SetErrorMode in
2001 dynload_win.c. The error is still reported properly.
2002
Georg Brandl3ee81df2008-05-17 18:14:43 +00002003- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002004 several extension methods and modules do not work without unicode
2005 support.
2006
Georg Brandl26543b12008-01-21 18:36:51 +00002007- Issue #1882: when compiling code from a string, encoding cookies in the
2008 second line of code were not always recognized correctly.
2009
Georg Brandl14404b62008-01-19 19:27:05 +00002010- Issue #1679: "0x" was taken as a valid integer literal.
2011
Georg Brandl6caad7d2008-01-26 14:19:22 +00002012- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002013 added.
2014
Christian Heimesc94e2b52008-01-14 04:13:37 +00002015- sys.float_info / PyFloat_GetInfo: The floating point information
2016 object was converted from a dict to a specialized structseq object.
2017
Georg Brandl3ee81df2008-05-17 18:14:43 +00002018- Patch #1816: Added sys.flags structseq. It exposes the status of
2019 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002020
Georg Brandl3ee81df2008-05-17 18:14:43 +00002021- Objects/structseq.c: Implemented new structseq representation. The
2022 patch makes structseqs (e.g. the return value of os.stat) more
2023 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002024
Georg Brandl3ee81df2008-05-17 18:14:43 +00002025- Patch #1700288: added a type attribute cache that caches method
2026 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002027
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002028- Bug #1776: __import__() no longer accepts filenames on any platform.
2029 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002030
Georg Brandlaed6c662008-01-07 17:25:53 +00002031- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2032
Georg Brandl3ee81df2008-05-17 18:14:43 +00002033- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2034 envvar and sys.dont_write_bytecode attribute. All these can be set
2035 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002036
Georg Brandl3ee81df2008-05-17 18:14:43 +00002037- Improve some exception messages when Windows fails to load an
2038 extension module. Now we get for example '%1 is not a valid Win32
2039 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002040
Georg Brandl3ee81df2008-05-17 18:14:43 +00002041- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002043- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2044 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002045
Christian Heimes0a8143f2007-12-18 23:22:54 +00002046- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002047 and INF. float("nan"), float("inf") and float("-inf") now work on
2048 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002049
Georg Brandl3ee81df2008-05-17 18:14:43 +00002050- Compiler now generates simpler and faster code for dictionary
2051 literals. The oparg for BUILD_MAP now indicates an estimated
2052 dictionary size. There is a new opcode, STORE_MAP, for adding
2053 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002054
Georg Brandl3ee81df2008-05-17 18:14:43 +00002055- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002063- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002064 SystemError.
2065
Nick Coghlanef01d822007-12-03 12:55:17 +00002066- PEP 366: Allow explicit relative imports when executing modules

2078
Georg Brandl3ee81df2008-05-17 18:14:43 +00002079- Issue #1460: The utf-7 incremental decoder did not accept truncated
2080 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002081
Georg Brandl3ee81df2008-05-17 18:14:43 +00002082- Patch #1739468: Directories and zipfiles containing a __main__.py
2083 file can now be directly executed by passing their name to the
2084 interpreter. The directory/zipfile is automatically inserted as the
2085 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002086
Georg Brandl3ee81df2008-05-17 18:14:43 +00002087- Issue #1265: Fix a problem with sys.settrace, if the tracing
2088 function uses a generator expression when at the same time the
2089 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002090
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002091- sets and frozensets now have an isdisjoint() method.
2092
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002093- optimize the performance of builtin.sum().
2094
Neal Norwitz44f326e2007-10-05 05:29:17 +00002095- Fix warnings found by the new version of the Coverity checker.
2096
Georg Brandl3ee81df2008-05-17 18:14:43 +00002097- The enumerate() builtin function is no longer bounded to sequences
2098 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2099 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Issue #1686386: Tuple's tp_repr did not take into account the
2102 possibility of having a self-referential tuple, which is possible
2103 from C code. Nor did object's tp_str consider that a type's tp_str
2104 could do something that could lead to an inifinite recursion.
2105 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2106 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002107
Georg Brandl3ee81df2008-05-17 18:14:43 +00002108- Issue #1164: It was possible to trigger deadlock when using the
2109 'print' statement to write to a file since the GIL was not released
2110 as needed. Now PyObject_Print() does the right thing along with
2111 various tp_print implementations of the built-in types and those in
2112 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002113
Georg Brandl3ee81df2008-05-17 18:14:43 +00002114- Issue #1147: Exceptions were directly allowing string exceptions in
2115 their throw() method even though string exceptions no longer
2116 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002117
Georg Brandl3ee81df2008-05-17 18:14:43 +00002118- Issue #1096: Prevent a segfault from getting the repr of a very
2119 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002120
Brett Cannon1e534b52007-09-07 04:18:30 +00002121- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002122 PyObject_Call() never calling back out to Python code to trigger
2123 recursion depth updates/checks. Required the creation of a static
2124 RuntimeError instance in case normalizing an exception put the
2125 recursion check value past its limit. Fixes crashers
2126 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002127
Georg Brandl3ee81df2008-05-17 18:14:43 +00002128- Patch #1031213: Decode source line in SyntaxErrors back to its

2132 with %G.
2133
Georg Brandl3ee81df2008-05-17 18:14:43 +00002134- Prevent expandtabs() on string and unicode objects from causing a
2135 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002141- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002142 __*__ attributes. (Some already existed, e.g., __doc__ and
2143 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002144
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002145- Add -3 option to the interpreter to warn about features that are
2146 deprecated and will be changed/removed in Python 3.0.
2147
Georg Brandl2134e752007-05-21 20:34:16 +00002148- Patch #1686487: you can now pass any mapping after '**' in function
2149 calls.
2150
Collin Winter62903052007-05-18 23:11:24 +00002151- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002152 "except E as target:". This is to provide forwards compatibility
2153 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002154
Brett Cannon229cee22007-05-05 01:34:02 +00002155- Deprecate BaseException.message as per PEP 352.
2156
Georg Brandl3ee81df2008-05-17 18:14:43 +00002157- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002158 inherited from a builtin base.
2159
Vinay Sajip8549ce32007-05-06 17:53:37 +00002160- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002161 setting a plain string, ie don't expand to single letter identifiers.
2162
Raymond Hettinger13936692007-04-11 18:40:58 +00002163- Request #1191699: Slices can now be pickled.
2164
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002165- Request #1193128: str.translate() now allows a None argument for
2166 translations that only remove characters without re-mapping the
2167 remaining characters.
2168
Georg Brandl5cb76c12007-03-21 09:00:39 +00002169- Patch #1682205: a TypeError while unpacking an iterable is no longer
2170 masked by a generic one with the message "unpack non-sequence".
2171
Neal Norwitzaa754b72007-03-21 06:39:48 +00002172- Remove unused file Python/fmod.c.
2173
Guido van Rossum143b5642007-03-23 04:58:42 +00002174- Bug #1683368: The object.__init__() and object.__new__() methods are
2175 now stricter in rejecting excess arguments. The only time when
2176 either allows excess arguments is when it is not overridden and the
2177 other one is. For backwards compatibility, when both are
2178 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002179 warning later). Also, type.__init__() insists on the same signature
2180 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2183 object to complex using its __complex__() method before falling back
2184 to the __float__() method. Therefore, the functions in the cmath
2185 module now can operate on objects that define a __complex__()
2186 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002187
Georg Brandl3ee81df2008-05-17 18:14:43 +00002188- Patch #1623563: allow __class__ assignment for classes with
2189 __slots__. The old and the new class are still required to have the
2190 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002191
Georg Brandl3ee81df2008-05-17 18:14:43 +00002192- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002195- Patch #1462488: Python no longer segfaults when
2196 ``object.__reduce_ex__()`` is called with an object that is faking
2197 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002198
Georg Brandl3ee81df2008-05-17 18:14:43 +00002199- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002202- Patch #1444529: the builtin compile() now accepts keyword arguments.
2203
Georg Brandl7b9c5552007-03-12 14:30:05 +00002204- Bug #1678647: write a newline after printing an exception in any
2205 case, even when converting the value to a string failed.
2206
Georg Brandl871f1bc2007-03-12 13:17:36 +00002207- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002208 its argument, if it exists. If not, it will work like before. This
2209 allows customizing the output of dir() in the presence of a
2210 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002211
Collin Winter276887b2007-03-12 16:11:39 +00002212- Patch #922167: Python no longer segfaults when faced with infinitely
2213 self-recursive reload() calls (as reported by bug #742342).
2214
Georg Brandl3ee81df2008-05-17 18:14:43 +00002215- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Patch #1491866: change the complex() constructor to allow
2219 parthensized forms. This means complex(repr(x)) now works instead of
2220 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002221
Georg Brandlaa2321b2007-03-07 00:40:28 +00002222- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002223 makes the filenames the warning module prints much more sensible
2224 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002225
Georg Brandl49aafc92007-03-07 00:34:46 +00002226- Variant of patch #697613: don't exit the interpreter on a SystemExit
2227 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002228 variable is given, but break into the interactive interpreter just
2229 like on other exceptions or normal program exit.

2728
Georg Brandlfb4b3b72007-04-24 15:27:13 +00002729- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
2730 (as opposed to the command line) will now write file names ending in
2731 ".cpp" too.
2732
Facundo Batistad918a652007-04-24 13:54:38 +00002733- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002734 the client's request was successfully received, understood, and
2735 accepted. Now in these cases no error is raised in urllib (issue
2736 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00002737
Georg Brandl3ee81df2008-05-17 18:14:43 +00002738- Bug #1290505: time.strptime's internal cache of locale information

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00002744- Added a timeout parameter to the constructor of other protocols
2745 (telnetlib, ftplib, smtplib and poplib). This is second part of the
2746 work started with create_connection() and timeout in httplib, and
2747 closes patch #723312.
2748
Vinay Sajip8549ce32007-05-06 17:53:37 +00002749- Patch #1676823: Added create_connection() to socket.py, which may be
2750 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00002751 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00002752
Martin v. Löwis0af33882007-03-23 13:27:15 +00002753- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
2761 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00002762 directories.
2763

2773
Georg Brandlf66b6032007-03-14 08:27:52 +00002774- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00002775 AttributeError instead of an IOError when the server's response
2776 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002777
Georg Brandl3ee81df2008-05-17 18:14:43 +00002778- Patch #957650: "%var%" environment variable references are now
2779 properly expanded in ntpath.expandvars(), also "~user" home
2780 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00002781
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782- Patch #1429539: pdb now correctly initializes the __main__ module
2783 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002784 correctly now.
2785
Georg Brandlbad6f192007-03-13 21:32:56 +00002786- The nonobvious commands.getstatus() function is now deprecated.

2792
Georg Brandl3ee81df2008-05-17 18:14:43 +00002793- Patch #1530482: add pydoc.render_doc() which returns the
2794 documentation for a thing instead of paging it to stdout, which
2795 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00002796
Georg Brandl3ee81df2008-05-17 18:14:43 +00002797- Patch #1533909: the timeit module now accepts callables in addition

2803 parameter which can be set to False to prevent the default
2804 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00002805
Georg Brandl9e6b4702007-03-13 18:15:41 +00002806- Patch #1581073: add a flag to textwrap that prevents the dropping of
2807 whitespace while wrapping.
2808
Georg Brandl92a6bae2007-03-13 17:43:32 +00002809- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002810 are set for invalid interpolation sequences that would lead to
2811 errors on reading back those values.

2825
Georg Brandl94fe3f52007-03-13 09:32:11 +00002826- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00002827 field names in its exception message if you try to write a record
2828 with a dictionary containing fields not in the CSV field names list.

2854 returned string up to the first NUL character.

2865
Georg Brandl3ee81df2008-05-17 18:14:43 +00002866- unittest now verifies more of its assumptions. In particular,
2867 TestCase and TestSuite subclasses (not instances) are no longer
2868 accepted in TestSuite.addTest(). This should cause no
2869 incompatibility since it never made sense with ordinary subclasses
2870 -- the failure just occurred later, with a more cumbersome
2871 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00002872

2880 given a unicode argument and os.listdir() returns unicode filenames.
2881
Georg Brandl3ee81df2008-05-17 18:14:43 +00002882- Patch #1673619: setup.py identifies extension modules it doesn't
2883 know how to build and those it knows how to build but that fail to
2884 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003259- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260 time so that opening a database previously created with the DB_DUP
3261 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3262 opens. Specifically: dictionary assignment to a DB object will
3263 replace all values for a given key when the database allows
3264 duplicate values. DB users should use DB.put(k, v) when they want
3265 to store duplicates; not DB[k] = v.

3272 characters with ASCII value less than 32. Also, it correctly quotes
3273 dots only if they occur on a single line, as opposed to the previous
3274 behavior of quoting dots if they are the second character of any
3275 line.
