43 file has been renamed, moved, or if it is accessed through different paths).
44 Patch by Ziga Seilnacht and Jean-Paul Calderone.
45
Georg Brandl734373c2009-01-03 21:55:17 +000046- Issue #4075: Use OutputDebugStringW in Py_FatalError.

72 exceptions.
73

80
Vinay Sajip6badbe92009-01-20 22:49:13 +000081- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +000082 method on file objects with closefd=False. The file descriptor is still
83 kept open but the file object behaves like a closed file. The ``FileIO``

85
Georg Brandlfa71a902008-12-05 09:08:28 +000086- Issue #3689: The list reversed iterator now supports __length_hint__

104
105- unittest.assertNotEqual() now uses the inequality operator (!=) instead
106 of the equality operator.
107
108- Issue #5663: better failure messages for unittest asserts. Default assertTrue

145 to wait 120 seconds for the socket to expire.
146
147- Adjusted _tkinter to compile without warnings when WITH_THREAD is not
148 defined (part of issue #5035).
149
Marc-André Lemburg152f2222009-03-25 19:52:04 +0000150- Issue #5561: Removed the sys.version_info shortcuts from platform's

152 output compared to previous Python versions.
153
Lars Gustäbel9e2a09a2009-03-22 20:22:29 +0000154- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop

286 302 conformant loader) will now work correctly in most cases (they
287 are still subject to the constraints that exist for all code running
288 from inside a module loaded via a PEP 302 loader and attempting to

Antoine Pitrou0668c622008-08-26 22:42:08 +0000645 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
646 mechanism. In the process, fix a bug where isinstance() and issubclass(),
647 when given a tuple of classes as second argument, were looking up
648 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
649 type object.

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

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000788What's New in Python 2.6 beta 3?
789================================
790
Barry Warsaw07a4a382008-08-21 01:15:08 +0000791*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000792
793Core and Builtins
794-----------------
795
Guido van Rossumf8402962008-08-20 15:01:50 +0000796- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
797 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
798 extensions do not automatically benefit from the class attribute
799 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
800 to their tp_flags field if they care. This is a backwards
801 compatibility feature; in 3.0, all types will use the cache by
802 default.
803
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000804- Keyword arguments can now follow starred arguments. (``f(a, *args,
805 keyword=23)`` is now valid syntax.)
806
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000807- ctypes function pointers that are COM methods have a boolean True
808 value again.
809
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000810- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
811 by denying s# to parse objects that have a releasebuffer procedure,
812 and introducing s*.
813
Georg Brandl1e13ea92008-08-11 09:07:59 +0000814- Issue #3537: Fix an assertion failure when an empty but presized dict
815 object was stored in the freelist.
816
Mark Dickinsonb6467572008-08-04 21:30:09 +0000817- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
818 ValueError consistently across platforms.
819
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000820- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
821 (64bit Unix, for example), unichr() would truncate its argument and return
822 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
823
Neal Norwitze7d8be82008-07-31 17:17:14 +0000824- Apply security patches from Apple.
825
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000826- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
827 PyErr_ExceptionMatches returns 0 when an exception occurs there.
828
Antoine Pitrou92f82162008-07-25 22:22:08 +0000829- Issue #1819: function calls with several named parameters are now on
830 average 35% faster (as measured by pybench).
831
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000832- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
833 the python debugger steps into a class statement: the free variables (local
834 variables defined in an outer scope) would be deleted from the outer scope.
835
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000836- Issue #2620: Overflow checking when allocating or reallocating memory
837 was not always being done properly in some python types and extension
838 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
839 all been updated to perform better checks and places in the code that
840 would previously leak memory on the error path when such an allocation
841 failed have been fixed.

850
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000851- Issue #2234: distutils failed for some versions of the cygwin compiler. The
852 version reported by these tools does not necessarily follow the python
853 version numbering scheme, so the module is less strict when parsing it.
854
Nick Coghlanf70385a2008-08-18 12:42:46 +0000855- Issue #2235: Added Py3k warnings for types which will become unhashable
856 under the stricter __hash__ inheritance rules in 3.0. Several types
857 which did not meet the rules for hash invariants and were already
858 unhashable in 3.0 have now been explicitly flagged as unhashable in
859 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
860 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
861
Brett Cannon88f801d2008-08-18 00:46:22 +0000862- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

870
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000871- Issue #3575: Incremental decoder's decode function now takes bytearray
872 by using 's*' instead of 't#'.
873
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000874- Issue #2222: Fixed reference leak when occured os.rename()
875 fails unicode conversion on 2nd parameter. (windows only)
876
Facundo Batista94f243a2008-08-17 03:38:39 +0000877- Issue 2464. urllib2 now supports a malformation in the URL received
878 in a redirect.
879
Brett Cannonabe423e2008-08-16 21:47:07 +0000880- Silence the DeprecationWarning raised when importing mimetools in

Brett Cannonabe423e2008-08-16 21:47:07 +0000882
Facundo Batistaeb90b782008-08-16 14:44:07 +0000883- Issue #2776: fixed small issue when handling an URL with double slash
884 after a 302 response in the case of not going through a proxy.
885
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000886- Issue #2676: in the email package, content-type parsing was hanging on
887 pathological input because of quadratic or exponential behaviour of a
888 regular expression.
889
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000890- Issue #3476: binary buffered reading through the new "io" library is now
891 thread-safe.
892
Brett Cannonbf3157b2008-08-14 05:00:03 +0000893- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
894 since mimetools itself is deprecated. Because modules are cached, all
895 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
896
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000897- Issue #3134: shutil referenced undefined WindowsError symbol.
898
Robert Schuppenies14646332008-08-10 11:01:53 +0000899- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
900 menu entries were not deleted.
901
Brett Cannon83e81842008-08-09 23:30:55 +0000902- Copied the implementation of reduce() to _functools.reduce() to have a
903 version that did not raise a DeprecationWarning under -3.
904
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000905- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
906 a MemoryError rather than silently stop the iteration.
907
Guido van Rossum59ce9012008-08-09 14:55:34 +0000908- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
909 to _sre.compile() will now be rejected. This should not affect anybody
910 since the re.compile() function never generates invalid re-bytecode.
911
Skip Montanaroa032bf42008-08-08 22:52:51 +0000912- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
913 upon first access it can be automatically initialized from the csv file if
914 it wasn't initialized during instantiation.
915
Brett Cannon3aa2a492008-08-06 22:28:09 +0000916- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as

988-----------------
989
Georg Brandl3e483f62008-07-16 22:57:41 +0000990- Issue #3156: Fix inconsistent behavior of the bytearray type: all
991 its methods now allow for items objects that can be converted to
992 an integer using operator.index().
993
Mark Dickinson64b7e502008-07-16 09:40:03 +0000994- Issue #3360: Fix incorrect parsing of '020000000000.0', which
995 produced a ValueError instead of giving the correct float.
996
Eric Smitha5fa5a22008-07-16 00:11:49 +0000997- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
998 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
999
Mark Dickinson7103aa42008-07-15 19:08:33 +00001000- Issue #3008: the float type has a new instance method 'float.hex'
1001 and a new class method 'float.fromhex' to convert floating-point
1002 numbers to and from hexadecimal strings, respectively.
1003
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001004- Issue #2235: __hash__ is once again inherited by default. To allow
1005 collections.Hashable to remain meaningful in the presence of the
1006 default hash implementation (object.__hash__), it is now possible
1007 to explicit block inheritance of hash by setting __hash__=None at
1008 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1009 level.
1010
Nick Coghlanb028f502008-07-13 14:52:36 +00001011- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1012 the parent module cannot be found while performing an absolute import.
1013 This means that an incorrectly defined __package__ attribute will
1014 now only prevent relative imports in that module rather than causing
1015 all imports from that module to fail.
1016
Nick Coghlan14ff9942008-07-08 14:21:42 +00001017- Issue #2517: Allow unicode messages in Exceptions again by correctly

1022 set to a custom object whose write() method happens to install
1023 another file in sys.stdout.
1024
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001025- Issue #3088: Corrected a race condition in classes derived from
1026 threading.local: the first member set by a thread could be saved in
1027 another thread's dictionary.
1028
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001029- Issue #3004: Minor change to slice.indices(): the start and stop
1030 arguments are now treated identically, making the behaviour easier
1031 to describe and understand. For example, slice(None, -10,
1032 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1033 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1034 10, -1).
1035
Georg Brandl278fc502008-07-19 12:46:12 +00001036- Issue #3219: Calling a function with repeated keyword arguments,
1037 f(a=2, a=23), would not cause a syntax error. This was a regression
1038 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001039
Georg Brandl278fc502008-07-19 12:46:12 +00001040- Issue #2862: Make int and float freelist management consistent with
1041 other freelists. Changes their CompactFreeList apis into
1042 ClearFreeList apis and calls them via gc.collect().

1048 api functions without holding the GIL, which could lead to a fatal
1049 error when they failed.
1050
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001051- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001076- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1077 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001078 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001079 content-length. The problem had been corrected in the 2.4 branch, but never
1080 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001095- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00001550- Issue #1631171: Re-implement the 'warnings' module in C (the
1551 original Python code has been kept as backup). This will allow for
1552 using the 'warning's machinery in such places as the parser where
1553 use of pure Python code is not possible. Both the ``showarning()``
1554 and ``formatwarning()`` gain an optional 'line' argument which is
1555 not called by default for backwards-compatibility reasons. Setting
1556 ``warnings.showwarning()`` to an implementation that lacks support
1557 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001620- Issue #2550: The approach used by client/server code for obtaining
1621 ports to listen on in network-oriented tests has been refined in an
1622 effort to facilitate running multiple instances of the entire
1623 regression test suite in parallel without issue.
1624 test_support.bind_port() has been fixed such that it will always
1625 return a unique port -- which wasn't always the case with the
1626 previous implementation, especially if socket options had been set
1627 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1628 new implementation of bind_port() will actually raise an exception
1629 if it is passed an AF_INET/SOCK_STREAM socket with either the
1630 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1631 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1632 the socket it's been passed. This currently only applies to
1633 Windows. This option prevents any other sockets from binding to the
1634 host/port we've bound to, thus removing the possibility of the
1635 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1636 when a second SOCK_STREAM socket binds and accepts to a host/port
1637 that's already been bound by another socket. The optional preferred
1638 port parameter to bind_port() has been removed. Under no
1639 circumstances should tests be hard coding ports!
1640
1641 test_support.find_unused_port() has also been introduced, which will
1642 pass a temporary socket object to bind_port() in order to obtain an
1643 unused port. The temporary socket object is then closed and
1644 deleted, and the port is returned. This method should only be used
1645 for obtaining an unused port in order to pass to an external program
1646 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1647 a parameter to a server-oriented class that doesn't give you direct
1648 access to the underlying socket used.
1649
1650 Finally, test_support.HOST has been introduced, which should be used
1651 for the host argument of any relevant socket calls (i.e. bind and
1652 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001653
1654 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001655 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001656 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1657 test_asynchat and test_socket_ssl.
1658
Georg Brandl3ee81df2008-05-17 18:14:43 +00001659 It is now possible for multiple instances of the regression test
1660 suite to run in parallel without issue.

1927-----------------
1928
Fred Drakea8ee94b2008-03-01 02:45:07 +00001929- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001930 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00001935
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001936- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001937 issue 215555 for a discussion.
1938
Eric Smitha73fbe72008-02-23 03:09:44 +00001939- Added the future_builtins module, which contains hex() and oct().
1940 These are the PEP 3127 version of these functions, designed to be
1941 compatible with the hex() and oct() builtins from Python 3.0. They
1942 differ slightly in their output formats from the existing, unchanged
1943 Python 2.6 builtins. The expected usage of the future_builtins
1944 module is:
1945 from future_builtins import hex, oct
1946
Eric Smith7ef40bf2008-02-20 23:34:22 +00001947- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1948 exponents for exponents with absolute value < 100. Follows C99
1949 standard. This is a change on Windows, which would use 3 digits.
1950 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1951 so that any alterations it does to the resulting string will be
1952 available in stringlib/formatter.h (for float.__format__).
1953
Eric Smith5a3c1352008-02-19 13:21:56 +00001954- Implemented PEP 3101, Advanced String Formatting. This adds a new
1955 builtin format(); a format() method for str and unicode; a
1956 __format__() method to object, str, unicode, int, long, float, and
1957 datetime; the class string.Formatter; and the C API
1958 PyObject_Format().
1959
Georg Brandl3ee81df2008-05-17 18:14:43 +00001960- Fixed several potential crashes, all caused by specially crafted
1961 __del__ methods exploiting objects in temporarily inconsistent
1962 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001963
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001964- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001965 prevent a possible crash: an Abstract Base Class would try to access
1966 a slot on a registered virtual subclass.

1973 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001974
Georg Brandl3ee81df2008-05-17 18:14:43 +00001975- Issue #2045: Fix an infinite recursion triggered when printing a

1980 list was not freed on interpreter shutdown.
1981
Georg Brandl3ee81df2008-05-17 18:14:43 +00001982- Limit free list of method and builtin function objects to 256

1986 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001987 to compact the internal free lists of pre-allocted ints and floats.
1988
Georg Brandl3ee81df2008-05-17 18:14:43 +00001989- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1990 calls. Python expected the return type int but the fork familie
1991 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002005- Patch #1473257: generator objects gain a gi_code attribute. This is
2006 the same object as the func_code attribute of the function that
2007 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002008
Georg Brandl3ee81df2008-05-17 18:14:43 +00002009- Issue #1920: "while 0" statements were completely removed by the
2010 compiler, even in the presence of an "else" clause, which is
2011 supposed to be run when the condition is false. Now the compiler
2012 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002013

Georg Brandl6caad7d2008-01-26 14:19:22 +00002031- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002032 added.
2033
Christian Heimesc94e2b52008-01-14 04:13:37 +00002034- sys.float_info / PyFloat_GetInfo: The floating point information
2035 object was converted from a dict to a specialized structseq object.
2036
Georg Brandl3ee81df2008-05-17 18:14:43 +00002037- Patch #1816: Added sys.flags structseq. It exposes the status of
2038 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002039
Georg Brandl3ee81df2008-05-17 18:14:43 +00002040- Objects/structseq.c: Implemented new structseq representation. The
2041 patch makes structseqs (e.g. the return value of os.stat) more
2042 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002043
Georg Brandl3ee81df2008-05-17 18:14:43 +00002044- Patch #1700288: added a type attribute cache that caches method
2045 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002046
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002047- Bug #1776: __import__() no longer accepts filenames on any platform.
2048 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002049
Georg Brandlaed6c662008-01-07 17:25:53 +00002050- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2051
Georg Brandl3ee81df2008-05-17 18:14:43 +00002052- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2053 envvar and sys.dont_write_bytecode attribute. All these can be set
2054 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002055
Georg Brandl3ee81df2008-05-17 18:14:43 +00002056- Improve some exception messages when Windows fails to load an
2057 extension module. Now we get for example '%1 is not a valid Win32
2058 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002059
Georg Brandl3ee81df2008-05-17 18:14:43 +00002060- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002062- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2063 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002064
Christian Heimes0a8143f2007-12-18 23:22:54 +00002065- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002066 and INF. float("nan"), float("inf") and float("-inf") now work on
2067 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002068
Georg Brandl3ee81df2008-05-17 18:14:43 +00002069- Compiler now generates simpler and faster code for dictionary
2070 literals. The oparg for BUILD_MAP now indicates an estimated
2071 dictionary size. There is a new opcode, STORE_MAP, for adding
2072 entries to the dictionary.

2090 running, and if the deallocation of its frames somehow calls the
2091 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002092

2097
Georg Brandl3ee81df2008-05-17 18:14:43 +00002098- Issue #1460: The utf-7 incremental decoder did not accept truncated
2099 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Patch #1739468: Directories and zipfiles containing a __main__.py
2102 file can now be directly executed by passing their name to the
2103 interpreter. The directory/zipfile is automatically inserted as the
2104 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002105
Georg Brandl3ee81df2008-05-17 18:14:43 +00002106- Issue #1265: Fix a problem with sys.settrace, if the tracing
2107 function uses a generator expression when at the same time the
2108 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002109
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002110- sets and frozensets now have an isdisjoint() method.
2111

2113
Neal Norwitz44f326e2007-10-05 05:29:17 +00002114- Fix warnings found by the new version of the Coverity checker.
2115
Georg Brandl3ee81df2008-05-17 18:14:43 +00002116- The enumerate() builtin function is no longer bounded to sequences
2117 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2118 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002119
Georg Brandl3ee81df2008-05-17 18:14:43 +00002120- Issue #1686386: Tuple's tp_repr did not take into account the
2121 possibility of having a self-referential tuple, which is possible
2122 from C code. Nor did object's tp_str consider that a type's tp_str
2123 could do something that could lead to an inifinite recursion.
2124 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2125 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002126
Georg Brandl3ee81df2008-05-17 18:14:43 +00002127- Issue #1164: It was possible to trigger deadlock when using the
2128 'print' statement to write to a file since the GIL was not released
2129 as needed. Now PyObject_Print() does the right thing along with
2130 various tp_print implementations of the built-in types and those in
2131 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002132
Georg Brandl3ee81df2008-05-17 18:14:43 +00002133- Issue #1147: Exceptions were directly allowing string exceptions in
2134 their throw() method even though string exceptions no longer
2135 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002136
Georg Brandl3ee81df2008-05-17 18:14:43 +00002137- Issue #1096: Prevent a segfault from getting the repr of a very
2138 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002139
Brett Cannon1e534b52007-09-07 04:18:30 +00002140- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002141 PyObject_Call() never calling back out to Python code to trigger
2142 recursion depth updates/checks. Required the creation of a static
2143 RuntimeError instance in case normalizing an exception put the
2144 recursion check value past its limit. Fixes crashers
2145 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002146
Georg Brandl3ee81df2008-05-17 18:14:43 +00002147- Patch #1031213: Decode source line in SyntaxErrors back to its

2151 with %G.
2152
Georg Brandl3ee81df2008-05-17 18:14:43 +00002153- Prevent expandtabs() on string and unicode objects from causing a
2154 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002160- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002161 __*__ attributes. (Some already existed, e.g., __doc__ and
2162 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002163
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002164- Add -3 option to the interpreter to warn about features that are
2165 deprecated and will be changed/removed in Python 3.0.
2166
Georg Brandl2134e752007-05-21 20:34:16 +00002167- Patch #1686487: you can now pass any mapping after '**' in function
2168 calls.
2169
Collin Winter62903052007-05-18 23:11:24 +00002170- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171 "except E as target:". This is to provide forwards compatibility
2172 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002173
Brett Cannon229cee22007-05-05 01:34:02 +00002174- Deprecate BaseException.message as per PEP 352.
2175
Georg Brandl3ee81df2008-05-17 18:14:43 +00002176- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002177 inherited from a builtin base.
2178
Vinay Sajip8549ce32007-05-06 17:53:37 +00002179- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002180 setting a plain string, ie don't expand to single letter identifiers.
2181
Raymond Hettinger13936692007-04-11 18:40:58 +00002182- Request #1191699: Slices can now be pickled.
2183
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002184- Request #1193128: str.translate() now allows a None argument for
2185 translations that only remove characters without re-mapping the
2186 remaining characters.
2187
Georg Brandl5cb76c12007-03-21 09:00:39 +00002188- Patch #1682205: a TypeError while unpacking an iterable is no longer
2189 masked by a generic one with the message "unpack non-sequence".
2190
Neal Norwitzaa754b72007-03-21 06:39:48 +00002191- Remove unused file Python/fmod.c.
2192
Guido van Rossum143b5642007-03-23 04:58:42 +00002193- Bug #1683368: The object.__init__() and object.__new__() methods are
2194 now stricter in rejecting excess arguments. The only time when
2195 either allows excess arguments is when it is not overridden and the
2196 other one is. For backwards compatibility, when both are
2197 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002198 warning later). Also, type.__init__() insists on the same signature
2199 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002200
Georg Brandl3ee81df2008-05-17 18:14:43 +00002201- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2202 object to complex using its __complex__() method before falling back
2203 to the __float__() method. Therefore, the functions in the cmath
2204 module now can operate on objects that define a __complex__()
2205 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002206
Georg Brandl3ee81df2008-05-17 18:14:43 +00002207- Patch #1623563: allow __class__ assignment for classes with
2208 __slots__. The old and the new class are still required to have the
2209 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002210
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002214- Patch #1462488: Python no longer segfaults when
2215 ``object.__reduce_ex__()`` is called with an object that is faking
2216 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002217
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002221- Patch #1444529: the builtin compile() now accepts keyword arguments.
2222
Georg Brandl7b9c5552007-03-12 14:30:05 +00002223- Bug #1678647: write a newline after printing an exception in any
2224 case, even when converting the value to a string failed.
2225
Georg Brandl871f1bc2007-03-12 13:17:36 +00002226- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002227 its argument, if it exists. If not, it will work like before. This
2228 allows customizing the output of dir() in the presence of a
2229 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002230
Collin Winter276887b2007-03-12 16:11:39 +00002231- Patch #922167: Python no longer segfaults when faced with infinitely
2232 self-recursive reload() calls (as reported by bug #742342).
2233
Georg Brandl3ee81df2008-05-17 18:14:43 +00002234- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002237- Patch #1491866: change the complex() constructor to allow
2238 parthensized forms. This means complex(repr(x)) now works instead of
2239 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002240
Georg Brandlaa2321b2007-03-07 00:40:28 +00002241- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002242 makes the filenames the warning module prints much more sensible
2243 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002244
Georg Brandl49aafc92007-03-07 00:34:46 +00002245- Variant of patch #697613: don't exit the interpreter on a SystemExit
2246 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002247 variable is given, but break into the interactive interpreter just
2248 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002256- Patch #1674228: when assigning a slice (old-style), check for the
2257 sq_ass_slice instead of the sq_slice slot.
2258
Georg Brandl3ee81df2008-05-17 18:14:43 +00002259- When printing an unraisable error, don't print exceptions. before
2260 the name. This duplicates the behavior whening normally printing
2261 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002262
Georg Brandl3ee81df2008-05-17 18:14:43 +00002263- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00002763- Added a timeout parameter to the constructor of other protocols
2764 (telnetlib, ftplib, smtplib and poplib). This is second part of the
2765 work started with create_connection() and timeout in httplib, and
2766 closes patch #723312.
2767
Vinay Sajip8549ce32007-05-06 17:53:37 +00002768- Patch #1676823: Added create_connection() to socket.py, which may be
2769 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00002770 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00002771

2792
Georg Brandlf66b6032007-03-14 08:27:52 +00002793- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00002794 AttributeError instead of an IOError when the server's response
2795 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002796
Georg Brandl3ee81df2008-05-17 18:14:43 +00002797- Patch #957650: "%var%" environment variable references are now
2798 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00002801- Patch #1429539: pdb now correctly initializes the __main__ module
2802 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00002803 correctly now.
2804
Georg Brandlbad6f192007-03-13 21:32:56 +00002805- The nonobvious commands.getstatus() function is now deprecated.

2811
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812- Patch #1530482: add pydoc.render_doc() which returns the
2813 documentation for a thing instead of paging it to stdout, which

2822 parameter which can be set to False to prevent the default
2823 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00002825- Patch #1581073: add a flag to textwrap that prevents the dropping of
2826 whitespace while wrapping.
2827
Georg Brandl92a6bae2007-03-13 17:43:32 +00002828- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002829 are set for invalid interpolation sequences that would lead to
2830 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00002831

Georg Brandl3ee81df2008-05-17 18:14:43 +00002846 field names in its exception message if you try to write a record
2847 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00002865

2873 returned string up to the first NUL character.
2874

2884
Georg Brandl3ee81df2008-05-17 18:14:43 +00002885- unittest now verifies more of its assumptions. In particular,
2886 TestCase and TestSuite subclasses (not instances) are no longer
2887 accepted in TestSuite.addTest(). This should cause no
2888 incompatibility since it never made sense with ordinary subclasses
2889 -- the failure just occurred later, with a more cumbersome
2890 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00002891

2900
Georg Brandl3ee81df2008-05-17 18:14:43 +00002901- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003279 time so that opening a database previously created with the DB_DUP
3280 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3281 opens. Specifically: dictionary assignment to a DB object will
3282 replace all values for a given key when the database allows
3283 duplicate values. DB users should use DB.put(k, v) when they want
3284 to store duplicates; not DB[k] = v.

3291 characters with ASCII value less than 32. Also, it correctly quotes
3292 dots only if they occur on a single line, as opposed to the previous
3293 behavior of quoting dots if they are the second character of any
3294 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003295

3640 of w# format code incorrectly truncated the length to an int, even
3641 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3642 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003672- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3673 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
