Georg Brandld2094602008-12-05 08:51:30 +000082 method on file objects with closefd=False. The file descriptor is still

265 302 conformant loader) will now work correctly in most cases (they
266 are still subject to the constraints that exist for all code running
267 from inside a module loaded via a PEP 302 loader and attempting to

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000598- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
599 PyString_FromFormat or PyErr_Format to display size_t values. The macro
600 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
601 ``printf`` function, whereas PyString_FromFormat has an independent

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000767What's New in Python 2.6 beta 3?
768================================
769
Barry Warsaw07a4a382008-08-21 01:15:08 +0000770*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000771
772Core and Builtins
773-----------------
774
Guido van Rossumf8402962008-08-20 15:01:50 +0000775- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
776 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
777 extensions do not automatically benefit from the class attribute
778 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
779 to their tp_flags field if they care. This is a backwards
780 compatibility feature; in 3.0, all types will use the cache by
781 default.
782
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000783- Keyword arguments can now follow starred arguments. (``f(a, *args,
784 keyword=23)`` is now valid syntax.)
785
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000786- ctypes function pointers that are COM methods have a boolean True
787 value again.
788
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000789- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
790 by denying s# to parse objects that have a releasebuffer procedure,
791 and introducing s*.
792
Georg Brandl1e13ea92008-08-11 09:07:59 +0000793- Issue #3537: Fix an assertion failure when an empty but presized dict
794 object was stored in the freelist.
795
Mark Dickinsonb6467572008-08-04 21:30:09 +0000796- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
797 ValueError consistently across platforms.
798
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000799- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
800 (64bit Unix, for example), unichr() would truncate its argument and return
801 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
802
Neal Norwitze7d8be82008-07-31 17:17:14 +0000803- Apply security patches from Apple.
804
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000805- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
806 PyErr_ExceptionMatches returns 0 when an exception occurs there.
807
Antoine Pitrou92f82162008-07-25 22:22:08 +0000808- Issue #1819: function calls with several named parameters are now on
809 average 35% faster (as measured by pybench).
810
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000811- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
812 the python debugger steps into a class statement: the free variables (local
813 variables defined in an outer scope) would be deleted from the outer scope.
814
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000815- Issue #2620: Overflow checking when allocating or reallocating memory
816 was not always being done properly in some python types and extension
817 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
818 all been updated to perform better checks and places in the code that
819 would previously leak memory on the error path when such an allocation
820 failed have been fixed.

829
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000830- Issue #2234: distutils failed for some versions of the cygwin compiler. The
831 version reported by these tools does not necessarily follow the python
832 version numbering scheme, so the module is less strict when parsing it.
833
Nick Coghlanf70385a2008-08-18 12:42:46 +0000834- Issue #2235: Added Py3k warnings for types which will become unhashable
835 under the stricter __hash__ inheritance rules in 3.0. Several types
836 which did not meet the rules for hash invariants and were already
837 unhashable in 3.0 have now been explicitly flagged as unhashable in
838 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
839 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
840
Brett Cannon88f801d2008-08-18 00:46:22 +0000841- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

849
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000850- Issue #3575: Incremental decoder's decode function now takes bytearray
851 by using 's*' instead of 't#'.
852
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000853- Issue #2222: Fixed reference leak when occured os.rename()
854 fails unicode conversion on 2nd parameter. (windows only)
855
Facundo Batista94f243a2008-08-17 03:38:39 +0000856- Issue 2464. urllib2 now supports a malformation in the URL received
857 in a redirect.
858

Brett Cannonabe423e2008-08-16 21:47:07 +0000861
Facundo Batistaeb90b782008-08-16 14:44:07 +0000862- Issue #2776: fixed small issue when handling an URL with double slash
863 after a 302 response in the case of not going through a proxy.
864
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000865- Issue #2676: in the email package, content-type parsing was hanging on
866 pathological input because of quadratic or exponential behaviour of a
867 regular expression.
868
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000869- Issue #3476: binary buffered reading through the new "io" library is now
870 thread-safe.
871
Brett Cannonbf3157b2008-08-14 05:00:03 +0000872- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
873 since mimetools itself is deprecated. Because modules are cached, all
874 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
875
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000876- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +0000878- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
879 menu entries were not deleted.
880
Brett Cannon83e81842008-08-09 23:30:55 +0000881- Copied the implementation of reduce() to _functools.reduce() to have a
882 version that did not raise a DeprecationWarning under -3.
883
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000884- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
885 a MemoryError rather than silently stop the iteration.
886
Guido van Rossum59ce9012008-08-09 14:55:34 +0000887- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
888 to _sre.compile() will now be rejected. This should not affect anybody
889 since the re.compile() function never generates invalid re-bytecode.
890
Skip Montanaroa032bf42008-08-08 22:52:51 +0000891- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
892 upon first access it can be automatically initialized from the csv file if
893 it wasn't initialized during instantiation.
894
Brett Cannon3aa2a492008-08-06 22:28:09 +0000895- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as

937 file name rather than a ZipInfo instance, so files are extracted with
938 mode 0600 rather than 000 under Unix.
939
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000940- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
941 argument in python 2.5, this broke code that subclassed Popen to include its
942 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000966Core and Builtins
967-----------------
968
Georg Brandl3e483f62008-07-16 22:57:41 +0000969- Issue #3156: Fix inconsistent behavior of the bytearray type: all
970 its methods now allow for items objects that can be converted to
971 an integer using operator.index().
972
Mark Dickinson64b7e502008-07-16 09:40:03 +0000973- Issue #3360: Fix incorrect parsing of '020000000000.0', which
974 produced a ValueError instead of giving the correct float.
975
Eric Smitha5fa5a22008-07-16 00:11:49 +0000976- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
977 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
978
Mark Dickinson7103aa42008-07-15 19:08:33 +0000979- Issue #3008: the float type has a new instance method 'float.hex'
980 and a new class method 'float.fromhex' to convert floating-point
981 numbers to and from hexadecimal strings, respectively.
982
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000983- Issue #2235: __hash__ is once again inherited by default. To allow
984 collections.Hashable to remain meaningful in the presence of the
985 default hash implementation (object.__hash__), it is now possible
986 to explicit block inheritance of hash by setting __hash__=None at
987 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
988 level.
989
Nick Coghlanb028f502008-07-13 14:52:36 +0000990- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
991 the parent module cannot be found while performing an absolute import.
992 This means that an incorrectly defined __package__ attribute will
993 now only prevent relative imports in that module rather than causing
994 all imports from that module to fail.
995
Nick Coghlan14ff9942008-07-08 14:21:42 +0000996- Issue #2517: Allow unicode messages in Exceptions again by correctly
997 bypassing the instance dictionary when looking up __unicode__ on
998 new-style classes.

1001 set to a custom object whose write() method happens to install
1002 another file in sys.stdout.
1003
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001004- Issue #3088: Corrected a race condition in classes derived from
1005 threading.local: the first member set by a thread could be saved in
1006 another thread's dictionary.
1007
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001008- Issue #3004: Minor change to slice.indices(): the start and stop
1009 arguments are now treated identically, making the behaviour easier
1010 to describe and understand. For example, slice(None, -10,
1011 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1012 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1013 10, -1).
1014
Georg Brandl278fc502008-07-19 12:46:12 +00001015- Issue #3219: Calling a function with repeated keyword arguments,
1016 f(a=2, a=23), would not cause a syntax error. This was a regression
1017 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001018
Georg Brandl278fc502008-07-19 12:46:12 +00001019- Issue #2862: Make int and float freelist management consistent with
1020 other freelists. Changes their CompactFreeList apis into
1021 ClearFreeList apis and calls them via gc.collect().

1027 api functions without holding the GIL, which could lead to a fatal
1028 error when they failed.
1029
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001030- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001055- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1056 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001057 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001058 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001074- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1533 and ``formatwarning()`` gain an optional 'line' argument which is
1534 not called by default for backwards-compatibility reasons. Setting
1535 ``warnings.showwarning()`` to an implementation that lacks support
1536 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001599- Issue #2550: The approach used by client/server code for obtaining
1600 ports to listen on in network-oriented tests has been refined in an
1601 effort to facilitate running multiple instances of the entire
1602 regression test suite in parallel without issue.
1603 test_support.bind_port() has been fixed such that it will always
1604 return a unique port -- which wasn't always the case with the
1605 previous implementation, especially if socket options had been set
1606 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1607 new implementation of bind_port() will actually raise an exception
1608 if it is passed an AF_INET/SOCK_STREAM socket with either the
1609 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1610 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1611 the socket it's been passed. This currently only applies to
1612 Windows. This option prevents any other sockets from binding to the
1613 host/port we've bound to, thus removing the possibility of the
1614 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1615 when a second SOCK_STREAM socket binds and accepts to a host/port
1616 that's already been bound by another socket. The optional preferred
1617 port parameter to bind_port() has been removed. Under no
1618 circumstances should tests be hard coding ports!
1619
1620 test_support.find_unused_port() has also been introduced, which will
1621 pass a temporary socket object to bind_port() in order to obtain an
1622 unused port. The temporary socket object is then closed and
1623 deleted, and the port is returned. This method should only be used
1624 for obtaining an unused port in order to pass to an external program
1625 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1626 a parameter to a server-oriented class that doesn't give you direct
1627 access to the underlying socket used.
1628
1629 Finally, test_support.HOST has been introduced, which should be used
1630 for the host argument of any relevant socket calls (i.e. bind and
1631 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001632
1633 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001634 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001635 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1636 test_asynchat and test_socket_ssl.
1637
Georg Brandl3ee81df2008-05-17 18:14:43 +00001638 It is now possible for multiple instances of the regression test
1639 suite to run in parallel without issue.

1906-----------------
1907
Fred Drakea8ee94b2008-03-01 02:45:07 +00001908- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001909 644. The mode is now inherited from the py file.

1912
1913- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001914
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001915- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001916 issue 215555 for a discussion.
1917
Eric Smitha73fbe72008-02-23 03:09:44 +00001918- Added the future_builtins module, which contains hex() and oct().
1919 These are the PEP 3127 version of these functions, designed to be
1920 compatible with the hex() and oct() builtins from Python 3.0. They
1921 differ slightly in their output formats from the existing, unchanged
1922 Python 2.6 builtins. The expected usage of the future_builtins
1923 module is:
1924 from future_builtins import hex, oct
1925
Eric Smith7ef40bf2008-02-20 23:34:22 +00001926- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1927 exponents for exponents with absolute value < 100. Follows C99
1928 standard. This is a change on Windows, which would use 3 digits.
1929 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1930 so that any alterations it does to the resulting string will be
1931 available in stringlib/formatter.h (for float.__format__).
1932
Eric Smith5a3c1352008-02-19 13:21:56 +00001933- Implemented PEP 3101, Advanced String Formatting. This adds a new
1934 builtin format(); a format() method for str and unicode; a
1935 __format__() method to object, str, unicode, int, long, float, and
1936 datetime; the class string.Formatter; and the C API
1937 PyObject_Format().
1938
Georg Brandl3ee81df2008-05-17 18:14:43 +00001939- Fixed several potential crashes, all caused by specially crafted
1940 __del__ methods exploiting objects in temporarily inconsistent
1941 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001942
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001943- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001944 prevent a possible crash: an Abstract Base Class would try to access
1945 a slot on a registered virtual subclass.

1951 in order to allow pymalloc to free more arenas. Python may give back
1952 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001953
Georg Brandl3ee81df2008-05-17 18:14:43 +00001954- Issue #2045: Fix an infinite recursion triggered when printing a
1955 subclass of collections.defaultdict, if its default_factory is set
1956 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001957
Christian Heimesf75dbef2008-02-08 00:11:31 +00001958- Fixed a minor memory leak in dictobject.c. The content of the free
1959 list was not freed on interpreter shutdown.
1960
Georg Brandl3ee81df2008-05-17 18:14:43 +00001961- Limit free list of method and builtin function objects to 256
1962 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001964- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1965 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001966 to compact the internal free lists of pre-allocted ints and floats.
1967
Georg Brandl3ee81df2008-05-17 18:14:43 +00001968- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1969 calls. Python expected the return type int but the fork familie
1970 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001971

Georg Brandl3ee81df2008-05-17 18:14:43 +00001984- Patch #1473257: generator objects gain a gi_code attribute. This is
1985 the same object as the func_code attribute of the function that
1986 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001987
Georg Brandl3ee81df2008-05-17 18:14:43 +00001988- Issue #1920: "while 0" statements were completely removed by the
1989 compiler, even in the presence of an "else" clause, which is
1990 supposed to be run when the condition is false. Now the compiler
1991 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001992

Georg Brandl3ee81df2008-05-17 18:14:43 +00002019- Objects/structseq.c: Implemented new structseq representation. The
2020 patch makes structseqs (e.g. the return value of os.stat) more
2021 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002022
Georg Brandl3ee81df2008-05-17 18:14:43 +00002023- Patch #1700288: added a type attribute cache that caches method
2024 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002025
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002026- Bug #1776: __import__() no longer accepts filenames on any platform.
2027 The first parameter to __import__() must be a valid module name.

2032 envvar and sys.dont_write_bytecode attribute. All these can be set
2033 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002035- Improve some exception messages when Windows fails to load an
2036 extension module. Now we get for example '%1 is not a valid Win32
2037 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002038

Christian Heimes0a8143f2007-12-18 23:22:54 +00002044- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002045 and INF. float("nan"), float("inf") and float("-inf") now work on
2046 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002048- Compiler now generates simpler and faster code for dictionary
2049 literals. The oparg for BUILD_MAP now indicates an estimated
2050 dictionary size. There is a new opcode, STORE_MAP, for adding
2051 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002080- Patch #1739468: Directories and zipfiles containing a __main__.py
2081 file can now be directly executed by passing their name to the
2082 interpreter. The directory/zipfile is automatically inserted as the
2083 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002085- Issue #1265: Fix a problem with sys.settrace, if the tracing
2086 function uses a generator expression when at the same time the
2087 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002088
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002089- sets and frozensets now have an isdisjoint() method.

2092
Neal Norwitz44f326e2007-10-05 05:29:17 +00002093- Fix warnings found by the new version of the Coverity checker.
2094
Georg Brandl3ee81df2008-05-17 18:14:43 +00002095- The enumerate() builtin function is no longer bounded to sequences
2096 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2097 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002098
Georg Brandl3ee81df2008-05-17 18:14:43 +00002099- Issue #1686386: Tuple's tp_repr did not take into account the
2100 possibility of having a self-referential tuple, which is possible
2101 from C code. Nor did object's tp_str consider that a type's tp_str
2102 could do something that could lead to an inifinite recursion.
2103 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2104 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002105
Georg Brandl3ee81df2008-05-17 18:14:43 +00002106- Issue #1164: It was possible to trigger deadlock when using the
2107 'print' statement to write to a file since the GIL was not released
2108 as needed. Now PyObject_Print() does the right thing along with
2109 various tp_print implementations of the built-in types and those in
2110 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002111
Georg Brandl3ee81df2008-05-17 18:14:43 +00002112- Issue #1147: Exceptions were directly allowing string exceptions in

2114 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00002118
Brett Cannon1e534b52007-09-07 04:18:30 +00002119- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002120 PyObject_Call() never calling back out to Python code to trigger
2121 recursion depth updates/checks. Required the creation of a static
2122 RuntimeError instance in case normalizing an exception put the
2123 recursion check value past its limit. Fixes crashers
2124 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002125

Neal Norwitz0ac60192007-05-27 04:08:54 +00002139- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002140 __*__ attributes. (Some already existed, e.g., __doc__ and
2141 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002142
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002143- Add -3 option to the interpreter to warn about features that are
2144 deprecated and will be changed/removed in Python 3.0.
2145
Georg Brandl2134e752007-05-21 20:34:16 +00002146- Patch #1686487: you can now pass any mapping after '**' in function
2147 calls.
2148
Collin Winter62903052007-05-18 23:11:24 +00002149- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002150 "except E as target:". This is to provide forwards compatibility
2151 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002152
Brett Cannon229cee22007-05-05 01:34:02 +00002153- Deprecate BaseException.message as per PEP 352.

2157
Vinay Sajip8549ce32007-05-06 17:53:37 +00002158- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002159 setting a plain string, ie don't expand to single letter identifiers.
2160
Raymond Hettinger13936692007-04-11 18:40:58 +00002161- Request #1191699: Slices can now be pickled.
2162
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002163- Request #1193128: str.translate() now allows a None argument for
2164 translations that only remove characters without re-mapping the
2165 remaining characters.
2166
Georg Brandl5cb76c12007-03-21 09:00:39 +00002167- Patch #1682205: a TypeError while unpacking an iterable is no longer
2168 masked by a generic one with the message "unpack non-sequence".
2169
Neal Norwitzaa754b72007-03-21 06:39:48 +00002170- Remove unused file Python/fmod.c.
2171
Guido van Rossum143b5642007-03-23 04:58:42 +00002172- Bug #1683368: The object.__init__() and object.__new__() methods are
2173 now stricter in rejecting excess arguments. The only time when
2174 either allows excess arguments is when it is not overridden and the
2175 other one is. For backwards compatibility, when both are
2176 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002177 warning later). Also, type.__init__() insists on the same signature
2178 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002179
Georg Brandl3ee81df2008-05-17 18:14:43 +00002180- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2181 object to complex using its __complex__() method before falling back
2182 to the __float__() method. Therefore, the functions in the cmath
2183 module now can operate on objects that define a __complex__()
2184 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002185
Georg Brandl3ee81df2008-05-17 18:14:43 +00002186- Patch #1623563: allow __class__ assignment for classes with
2187 __slots__. The old and the new class are still required to have the
2188 same slot names.

2201
Georg Brandl7b9c5552007-03-12 14:30:05 +00002202- Bug #1678647: write a newline after printing an exception in any
2203 case, even when converting the value to a string failed.
2204
Georg Brandl871f1bc2007-03-12 13:17:36 +00002205- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002206 its argument, if it exists. If not, it will work like before. This
2207 allows customizing the output of dir() in the presence of a
2208 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002209
Collin Winter276887b2007-03-12 16:11:39 +00002210- Patch #922167: Python no longer segfaults when faced with infinitely
2211 self-recursive reload() calls (as reported by bug #742342).
2212
Georg Brandl3ee81df2008-05-17 18:14:43 +00002213- Patch #1675981: remove unreachable code from ``type.__new__()``

2217 parthensized forms. This means complex(repr(x)) now works instead of
2218 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002219
Georg Brandlaa2321b2007-03-07 00:40:28 +00002220- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002221 makes the filenames the warning module prints much more sensible
2222 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002223

Georg Brandl0fca97a2007-03-05 22:28:08 +00002235- Patch #1674228: when assigning a slice (old-style), check for the
2236 sq_ass_slice instead of the sq_slice slot.
2237
Georg Brandl3ee81df2008-05-17 18:14:43 +00002238- When printing an unraisable error, don't print exceptions. before
2239 the name. This duplicates the behavior whening normally printing
2240 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002773 AttributeError instead of an IOError when the server's response
2774 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002775

Georg Brandl3ee81df2008-05-17 18:14:43 +00002780- Patch #1429539: pdb now correctly initializes the __main__ module
2781 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002782 correctly now.
2783

2790
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Patch #1530482: add pydoc.render_doc() which returns the

2806
Georg Brandl92a6bae2007-03-13 17:43:32 +00002807- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808 are set for invalid interpolation sequences that would lead to
2809 errors on reading back those values.

2852 returned string up to the first NUL character.

2863
Georg Brandl3ee81df2008-05-17 18:14:43 +00002864- unittest now verifies more of its assumptions. In particular,
2865 TestCase and TestSuite subclasses (not instances) are no longer
2866 accepted in TestSuite.addTest(). This should cause no
2867 incompatibility since it never made sense with ordinary subclasses
2868 -- the failure just occurred later, with a more cumbersome
2869 exception.

3240 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003257- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258 time so that opening a database previously created with the DB_DUP
3259 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3260 opens. Specifically: dictionary assignment to a DB object will
3261 replace all values for a given key when the database allows
3262 duplicate values. DB users should use DB.put(k, v) when they want
3263 to store duplicates; not DB[k] = v.

3270 characters with ASCII value less than 32. Also, it correctly quotes
3271 dots only if they occur on a single line, as opposed to the previous
3272 behavior of quoting dots if they are the second character of any
3273 line.

3619 of w# format code incorrectly truncated the length to an int, even
3620 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3621 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003651- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3652 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
