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.

59
60- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
61 systems.
62

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__

256- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
257 302 conformant loader) will now work correctly in most cases (they
258 are still subject to the constraints that exist for all code running
259 from inside a module loaded via a PEP 302 loader and attempting to
260 perform IO operations based on __file__). Original patch by

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000590- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

592 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
593 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitrou0668c622008-08-26 22:42:08 +0000616 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
617 mechanism. In the process, fix a bug where isinstance() and issubclass(),

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000759What's New in Python 2.6 beta 3?
760================================
761
Barry Warsaw07a4a382008-08-21 01:15:08 +0000762*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000763
764Core and Builtins
765-----------------
766
Guido van Rossumf8402962008-08-20 15:01:50 +0000767- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
768 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
769 extensions do not automatically benefit from the class attribute
770 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
771 to their tp_flags field if they care. This is a backwards
772 compatibility feature; in 3.0, all types will use the cache by
773 default.
774
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000775- Keyword arguments can now follow starred arguments. (``f(a, *args,
776 keyword=23)`` is now valid syntax.)
777
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000778- ctypes function pointers that are COM methods have a boolean True
779 value again.
780
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000781- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
782 by denying s# to parse objects that have a releasebuffer procedure,
783 and introducing s*.
784
Georg Brandl1e13ea92008-08-11 09:07:59 +0000785- Issue #3537: Fix an assertion failure when an empty but presized dict
786 object was stored in the freelist.
787
Mark Dickinsonb6467572008-08-04 21:30:09 +0000788- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
789 ValueError consistently across platforms.
790
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000791- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
792 (64bit Unix, for example), unichr() would truncate its argument and return
793 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
794
Neal Norwitze7d8be82008-07-31 17:17:14 +0000795- Apply security patches from Apple.
796
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000797- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
798 PyErr_ExceptionMatches returns 0 when an exception occurs there.
799
Antoine Pitrou92f82162008-07-25 22:22:08 +0000800- Issue #1819: function calls with several named parameters are now on
801 average 35% faster (as measured by pybench).
802
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000803- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
804 the python debugger steps into a class statement: the free variables (local
805 variables defined in an outer scope) would be deleted from the outer scope.
806
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000807- Issue #2620: Overflow checking when allocating or reallocating memory
808 was not always being done properly in some python types and extension
809 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
810 all been updated to perform better checks and places in the code that
811 would previously leak memory on the error path when such an allocation
812 failed have been fixed.

821
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000822- Issue #2234: distutils failed for some versions of the cygwin compiler. The
823 version reported by these tools does not necessarily follow the python
824 version numbering scheme, so the module is less strict when parsing it.
825
Nick Coghlanf70385a2008-08-18 12:42:46 +0000826- Issue #2235: Added Py3k warnings for types which will become unhashable
827 under the stricter __hash__ inheritance rules in 3.0. Several types
828 which did not meet the rules for hash invariants and were already
829 unhashable in 3.0 have now been explicitly flagged as unhashable in
830 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
831 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
832
Brett Cannon88f801d2008-08-18 00:46:22 +0000833- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

841
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000842- Issue #3575: Incremental decoder's decode function now takes bytearray
843 by using 's*' instead of 't#'.
844
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000845- Issue #2222: Fixed reference leak when occured os.rename()
846 fails unicode conversion on 2nd parameter. (windows only)
847
Facundo Batista94f243a2008-08-17 03:38:39 +0000848- Issue 2464. urllib2 now supports a malformation in the URL received
849 in a redirect.

Brett Cannonabe423e2008-08-16 21:47:07 +0000853
Facundo Batistaeb90b782008-08-16 14:44:07 +0000854- Issue #2776: fixed small issue when handling an URL with double slash
855 after a 302 response in the case of not going through a proxy.
856
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000857- Issue #2676: in the email package, content-type parsing was hanging on
858 pathological input because of quadratic or exponential behaviour of a
859 regular expression.
860
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000861- Issue #3476: binary buffered reading through the new "io" library is now
862 thread-safe.
863
Brett Cannonbf3157b2008-08-14 05:00:03 +0000864- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
865 since mimetools itself is deprecated. Because modules are cached, all
866 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
867
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000868- Issue #3134: shutil referenced undefined WindowsError symbol.
869
Robert Schuppenies14646332008-08-10 11:01:53 +0000870- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
871 menu entries were not deleted.
872
Brett Cannon83e81842008-08-09 23:30:55 +0000873- Copied the implementation of reduce() to _functools.reduce() to have a
874 version that did not raise a DeprecationWarning under -3.
875
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000876- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
877 a MemoryError rather than silently stop the iteration.
878
Guido van Rossum59ce9012008-08-09 14:55:34 +0000879- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
880 to _sre.compile() will now be rejected. This should not affect anybody
881 since the re.compile() function never generates invalid re-bytecode.
882
Skip Montanaroa032bf42008-08-08 22:52:51 +0000883- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
884 upon first access it can be automatically initialized from the csv file if
885 it wasn't initialized during instantiation.
886
Brett Cannon3aa2a492008-08-06 22:28:09 +0000887- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as

929 file name rather than a ZipInfo instance, so files are extracted with
930 mode 0600 rather than 000 under Unix.
931
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000932- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

943
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000944- Issue #2235: the C API function PyObject_HashNotImplemented and its
945 interaction with the tp_hash slot (added in 2.6b2) are now documented
946
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000947- Issue #643841: The language reference now provides more detailed
948 coverage of the lookup process for special methods. The disclaimers
949 regarding lack of coverage of new-style classes have also been
950 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000958Core and Builtins
959-----------------
960
Georg Brandl3e483f62008-07-16 22:57:41 +0000961- Issue #3156: Fix inconsistent behavior of the bytearray type: all
962 its methods now allow for items objects that can be converted to
963 an integer using operator.index().
964
Mark Dickinson64b7e502008-07-16 09:40:03 +0000965- Issue #3360: Fix incorrect parsing of '020000000000.0', which
966 produced a ValueError instead of giving the correct float.
967
Eric Smitha5fa5a22008-07-16 00:11:49 +0000968- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
969 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
970
Mark Dickinson7103aa42008-07-15 19:08:33 +0000971- Issue #3008: the float type has a new instance method 'float.hex'
972 and a new class method 'float.fromhex' to convert floating-point
973 numbers to and from hexadecimal strings, respectively.
974
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000975- Issue #2235: __hash__ is once again inherited by default. To allow
976 collections.Hashable to remain meaningful in the presence of the
977 default hash implementation (object.__hash__), it is now possible
978 to explicit block inheritance of hash by setting __hash__=None at
979 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
980 level.
981
Nick Coghlanb028f502008-07-13 14:52:36 +0000982- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
983 the parent module cannot be found while performing an absolute import.
984 This means that an incorrectly defined __package__ attribute will
985 now only prevent relative imports in that module rather than causing
986 all imports from that module to fail.
987
Nick Coghlan14ff9942008-07-08 14:21:42 +0000988- Issue #2517: Allow unicode messages in Exceptions again by correctly
989 bypassing the instance dictionary when looking up __unicode__ on
990 new-style classes.
991
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000992- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
993 set to a custom object whose write() method happens to install
994 another file in sys.stdout.
995
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000996- Issue #3088: Corrected a race condition in classes derived from
997 threading.local: the first member set by a thread could be saved in
998 another thread's dictionary.
999
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001000- Issue #3004: Minor change to slice.indices(): the start and stop
1001 arguments are now treated identically, making the behaviour easier
1002 to describe and understand. For example, slice(None, -10,
1003 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1004 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1005 10, -1).
1006
Georg Brandl278fc502008-07-19 12:46:12 +00001007- Issue #3219: Calling a function with repeated keyword arguments,
1008 f(a=2, a=23), would not cause a syntax error. This was a regression
1009 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001010
Georg Brandl278fc502008-07-19 12:46:12 +00001011- Issue #2862: Make int and float freelist management consistent with
1012 other freelists. Changes their CompactFreeList apis into
1013 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001014

1016-------
1017
Thomas Heller57adf222008-08-14 19:10:48 +00001018- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1019 api functions without holding the GIL, which could lead to a fatal
1020 error when they failed.
1021
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001022- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
1023

1031 ForkingPickler.register() to resolve conflict with ctypes.
1032
Vinay Sajip51e65192008-07-18 09:01:10 +00001033- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001034
Thomas Heller880f5292008-07-15 19:39:38 +00001035- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1036 a valid dlerror() message.
1037
Thomas Heller2bad6572008-07-15 17:19:50 +00001038- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1039 incomplete structure was created.
1040

1044
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001045- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001046
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001047- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1048 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001049 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001050 content-length. The problem had been corrected in the 2.4 branch, but never
1051 merged into trunk.
1052
Georg Brandle78fbcc2008-07-05 10:13:36 +00001053- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00001061 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001062

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001064 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001065
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001066- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1067 handling is now the same as that of other special attributes like __name__).
1068
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001069- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1070 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00001521- Issue #1631171: Re-implement the 'warnings' module in C (the
1522 original Python code has been kept as backup). This will allow for
1523 using the 'warning's machinery in such places as the parser where
1524 use of pure Python code is not possible. Both the ``showarning()``
1525 and ``formatwarning()`` gain an optional 'line' argument which is
1526 not called by default for backwards-compatibility reasons. Setting
1527 ``warnings.showwarning()`` to an implementation that lacks support
1528 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001591- Issue #2550: The approach used by client/server code for obtaining
1592 ports to listen on in network-oriented tests has been refined in an
1593 effort to facilitate running multiple instances of the entire
1594 regression test suite in parallel without issue.
1595 test_support.bind_port() has been fixed such that it will always
1596 return a unique port -- which wasn't always the case with the
1597 previous implementation, especially if socket options had been set
1598 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1599 new implementation of bind_port() will actually raise an exception
1600 if it is passed an AF_INET/SOCK_STREAM socket with either the
1601 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1602 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1603 the socket it's been passed. This currently only applies to
1604 Windows. This option prevents any other sockets from binding to the
1605 host/port we've bound to, thus removing the possibility of the
1606 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1607 when a second SOCK_STREAM socket binds and accepts to a host/port
1608 that's already been bound by another socket. The optional preferred
1609 port parameter to bind_port() has been removed. Under no
1610 circumstances should tests be hard coding ports!
1611
1612 test_support.find_unused_port() has also been introduced, which will
1613 pass a temporary socket object to bind_port() in order to obtain an
1614 unused port. The temporary socket object is then closed and
1615 deleted, and the port is returned. This method should only be used
1616 for obtaining an unused port in order to pass to an external program
1617 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1618 a parameter to a server-oriented class that doesn't give you direct
1619 access to the underlying socket used.
1620
1621 Finally, test_support.HOST has been introduced, which should be used
1622 for the host argument of any relevant socket calls (i.e. bind and
1623 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001624
1625 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001626 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001627 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1628 test_asynchat and test_socket_ssl.
1629
Georg Brandl3ee81df2008-05-17 18:14:43 +00001630 It is now possible for multiple instances of the regression test
1631 suite to run in parallel without issue.

1898-----------------
1899
Fred Drakea8ee94b2008-03-01 02:45:07 +00001900- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001901 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001902
Georg Brandlad61bc82008-02-23 15:11:18 +00001903- Issue #2067: file.__exit__() now calls subclasses' close() method.
1904
1905- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001906
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001907- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001908 issue 215555 for a discussion.
1909
Eric Smitha73fbe72008-02-23 03:09:44 +00001910- Added the future_builtins module, which contains hex() and oct().
1911 These are the PEP 3127 version of these functions, designed to be
1912 compatible with the hex() and oct() builtins from Python 3.0. They
1913 differ slightly in their output formats from the existing, unchanged
1914 Python 2.6 builtins. The expected usage of the future_builtins
1915 module is:
1916 from future_builtins import hex, oct
1917
Eric Smith7ef40bf2008-02-20 23:34:22 +00001918- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1919 exponents for exponents with absolute value < 100. Follows C99
1920 standard. This is a change on Windows, which would use 3 digits.
1921 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1922 so that any alterations it does to the resulting string will be
1923 available in stringlib/formatter.h (for float.__format__).
1924
Eric Smith5a3c1352008-02-19 13:21:56 +00001925- Implemented PEP 3101, Advanced String Formatting. This adds a new
1926 builtin format(); a format() method for str and unicode; a
1927 __format__() method to object, str, unicode, int, long, float, and
1928 datetime; the class string.Formatter; and the C API
1929 PyObject_Format().
1930
Georg Brandl3ee81df2008-05-17 18:14:43 +00001931- Fixed several potential crashes, all caused by specially crafted
1932 __del__ methods exploiting objects in temporarily inconsistent
1933 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001934
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001935- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001936 prevent a possible crash: an Abstract Base Class would try to access
1937 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001938
Georg Brandl3ee81df2008-05-17 18:14:43 +00001939- Fixed repr() and str() of complex numbers with infinity or nan as
1940 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001941
Georg Brandl3ee81df2008-05-17 18:14:43 +00001942- Clear all free lists during a gc.collect() of the highest generation
1943 in order to allow pymalloc to free more arenas. Python may give back
1944 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001945
Georg Brandl3ee81df2008-05-17 18:14:43 +00001946- Issue #2045: Fix an infinite recursion triggered when printing a
1947 subclass of collections.defaultdict, if its default_factory is set
1948 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001949
Christian Heimesf75dbef2008-02-08 00:11:31 +00001950- Fixed a minor memory leak in dictobject.c. The content of the free
1951 list was not freed on interpreter shutdown.
1952
Georg Brandl3ee81df2008-05-17 18:14:43 +00001953- Limit free list of method and builtin function objects to 256
1954 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001955
Georg Brandl3ee81df2008-05-17 18:14:43 +00001956- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1957 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001958 to compact the internal free lists of pre-allocted ints and floats.
1959
Georg Brandl3ee81df2008-05-17 18:14:43 +00001960- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1961 calls. Python expected the return type int but the fork familie
1962 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001963
Georg Brandl3ee81df2008-05-17 18:14:43 +00001964- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1965 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001966
Georg Brandl3ee81df2008-05-17 18:14:43 +00001967- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1968 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001969
Georg Brandl3ee81df2008-05-17 18:14:43 +00001970- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
1971 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00001972
Georg Brandl3ee81df2008-05-17 18:14:43 +00001973- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1974 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001975
Georg Brandl3ee81df2008-05-17 18:14:43 +00001976- Patch #1473257: generator objects gain a gi_code attribute. This is
1977 the same object as the func_code attribute of the function that
1978 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001979
Georg Brandl3ee81df2008-05-17 18:14:43 +00001980- Issue #1920: "while 0" statements were completely removed by the
1981 compiler, even in the presence of an "else" clause, which is
1982 supposed to be run when the condition is false. Now the compiler
1983 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001984
Guido van Rossumeead05f2008-01-24 18:21:02 +00001985- A few crashers fixed: weakref_in_del.py (issue #1377858);
1986 loosing_dict_ref.py (issue #1303614, test67.py);
1987 borrowed_ref_[34].py (not in tracker).
1988
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001989- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001990 suppressed while an extension is loaded by calling SetErrorMode in
1991 dynload_win.c. The error is still reported properly.
1992
Georg Brandl3ee81df2008-05-17 18:14:43 +00001993- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001994 several extension methods and modules do not work without unicode
1995 support.
1996
Georg Brandl26543b12008-01-21 18:36:51 +00001997- Issue #1882: when compiling code from a string, encoding cookies in the
1998 second line of code were not always recognized correctly.
1999
Georg Brandl14404b62008-01-19 19:27:05 +00002000- Issue #1679: "0x" was taken as a valid integer literal.
2001
Georg Brandl6caad7d2008-01-26 14:19:22 +00002002- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002003 added.
2004
Christian Heimesc94e2b52008-01-14 04:13:37 +00002005- sys.float_info / PyFloat_GetInfo: The floating point information
2006 object was converted from a dict to a specialized structseq object.
2007
Georg Brandl3ee81df2008-05-17 18:14:43 +00002008- Patch #1816: Added sys.flags structseq. It exposes the status of
2009 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002010
Georg Brandl3ee81df2008-05-17 18:14:43 +00002011- Objects/structseq.c: Implemented new structseq representation. The
2012 patch makes structseqs (e.g. the return value of os.stat) more
2013 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002014
Georg Brandl3ee81df2008-05-17 18:14:43 +00002015- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002023- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2024 envvar and sys.dont_write_bytecode attribute. All these can be set
2025 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002027- Improve some exception messages when Windows fails to load an
2028 extension module. Now we get for example '%1 is not a valid Win32
2029 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002030

Christian Heimes0a8143f2007-12-18 23:22:54 +00002036- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002037 and INF. float("nan"), float("inf") and float("-inf") now work on
2038 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002040- Compiler now generates simpler and faster code for dictionary
2041 literals. The oparg for BUILD_MAP now indicates an estimated
2042 dictionary size. There is a new opcode, STORE_MAP, for adding
2043 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002072- Patch #1739468: Directories and zipfiles containing a __main__.py
2073 file can now be directly executed by passing their name to the
2074 interpreter. The directory/zipfile is automatically inserted as the
2075 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002076
Georg Brandl3ee81df2008-05-17 18:14:43 +00002077- Issue #1265: Fix a problem with sys.settrace, if the tracing
2078 function uses a generator expression when at the same time the
2079 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002080
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002081- sets and frozensets now have an isdisjoint() method.

2086
Georg Brandl3ee81df2008-05-17 18:14:43 +00002087- The enumerate() builtin function is no longer bounded to sequences
2088 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2089 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002090
Georg Brandl3ee81df2008-05-17 18:14:43 +00002091- Issue #1686386: Tuple's tp_repr did not take into account the
2092 possibility of having a self-referential tuple, which is possible
2093 from C code. Nor did object's tp_str consider that a type's tp_str
2094 could do something that could lead to an inifinite recursion.
2095 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2096 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002097
Georg Brandl3ee81df2008-05-17 18:14:43 +00002098- Issue #1164: It was possible to trigger deadlock when using the
2099 'print' statement to write to a file since the GIL was not released
2100 as needed. Now PyObject_Print() does the right thing along with
2101 various tp_print implementations of the built-in types and those in
2102 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002103
Georg Brandl3ee81df2008-05-17 18:14:43 +00002104- Issue #1147: Exceptions were directly allowing string exceptions in
2105 their throw() method even though string exceptions no longer
2106 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002107
Georg Brandl3ee81df2008-05-17 18:14:43 +00002108- Issue #1096: Prevent a segfault from getting the repr of a very
2109 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002110
Brett Cannon1e534b52007-09-07 04:18:30 +00002111- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002112 PyObject_Call() never calling back out to Python code to trigger
2113 recursion depth updates/checks. Required the creation of a static
2114 RuntimeError instance in case normalizing an exception put the
2115 recursion check value past its limit. Fixes crashers
2116 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002117

Neal Norwitz0ac60192007-05-27 04:08:54 +00002131- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002132 __*__ attributes. (Some already existed, e.g., __doc__ and
2133 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002134
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002135- Add -3 option to the interpreter to warn about features that are
2136 deprecated and will be changed/removed in Python 3.0.
2137
Georg Brandl2134e752007-05-21 20:34:16 +00002138- Patch #1686487: you can now pass any mapping after '**' in function
2139 calls.
2140
Collin Winter62903052007-05-18 23:11:24 +00002141- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002142 "except E as target:". This is to provide forwards compatibility
2143 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002144
Brett Cannon229cee22007-05-05 01:34:02 +00002145- Deprecate BaseException.message as per PEP 352.
2146
Georg Brandl3ee81df2008-05-17 18:14:43 +00002147- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002148 inherited from a builtin base.
2149
Vinay Sajip8549ce32007-05-06 17:53:37 +00002150- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002151 setting a plain string, ie don't expand to single letter identifiers.
2152
Raymond Hettinger13936692007-04-11 18:40:58 +00002153- Request #1191699: Slices can now be pickled.
2154
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002155- Request #1193128: str.translate() now allows a None argument for
2156 translations that only remove characters without re-mapping the
2157 remaining characters.
2158
Georg Brandl5cb76c12007-03-21 09:00:39 +00002159- Patch #1682205: a TypeError while unpacking an iterable is no longer
2160 masked by a generic one with the message "unpack non-sequence".
2161
Neal Norwitzaa754b72007-03-21 06:39:48 +00002162- Remove unused file Python/fmod.c.
2163
Guido van Rossum143b5642007-03-23 04:58:42 +00002164- Bug #1683368: The object.__init__() and object.__new__() methods are
2165 now stricter in rejecting excess arguments. The only time when
2166 either allows excess arguments is when it is not overridden and the
2167 other one is. For backwards compatibility, when both are
2168 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002169 warning later). Also, type.__init__() insists on the same signature
2170 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002171
Georg Brandl3ee81df2008-05-17 18:14:43 +00002172- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2173 object to complex using its __complex__() method before falling back
2174 to the __float__() method. Therefore, the functions in the cmath
2175 module now can operate on objects that define a __complex__()
2176 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002177
Georg Brandl3ee81df2008-05-17 18:14:43 +00002178- Patch #1623563: allow __class__ assignment for classes with
2179 __slots__. The old and the new class are still required to have the
2180 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Patch #1642547: Fix an error/crash when encountering syntax errors

2186 ``object.__reduce_ex__()`` is called with an object that is faking
2187 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002188
Georg Brandl3ee81df2008-05-17 18:14:43 +00002189- Patch #1680015: Don't modify __slots__ tuple if it contains an

2193
Georg Brandl7b9c5552007-03-12 14:30:05 +00002194- Bug #1678647: write a newline after printing an exception in any
2195 case, even when converting the value to a string failed.
2196
Georg Brandl871f1bc2007-03-12 13:17:36 +00002197- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002198 its argument, if it exists. If not, it will work like before. This
2199 allows customizing the output of dir() in the presence of a
2200 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002201
Collin Winter276887b2007-03-12 16:11:39 +00002202- Patch #922167: Python no longer segfaults when faced with infinitely
2203 self-recursive reload() calls (as reported by bug #742342).
2204
Georg Brandl3ee81df2008-05-17 18:14:43 +00002205- Patch #1675981: remove unreachable code from ``type.__new__()``

2209 parthensized forms. This means complex(repr(x)) now works instead of
2210 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002211
Georg Brandlaa2321b2007-03-07 00:40:28 +00002212- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002213 makes the filenames the warning module prints much more sensible
2214 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002215
Georg Brandl49aafc92007-03-07 00:34:46 +00002216- Variant of patch #697613: don't exit the interpreter on a SystemExit
2217 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218 variable is given, but break into the interactive interpreter just
2219 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002227- Patch #1674228: when assigning a slice (old-style), check for the
2228 sq_ass_slice instead of the sq_slice slot.
2229
Georg Brandl3ee81df2008-05-17 18:14:43 +00002230- When printing an unraisable error, don't print exceptions. before
2231 the name. This duplicates the behavior whening normally printing
2232 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002765 AttributeError instead of an IOError when the server's response
2766 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00002767

Georg Brandl3ee81df2008-05-17 18:14:43 +00002783- Patch #1530482: add pydoc.render_doc() which returns the

2798
Georg Brandl92a6bae2007-03-13 17:43:32 +00002799- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800 are set for invalid interpolation sequences that would lead to
2801 errors on reading back those values.

2844 returned string up to the first NUL character.

2855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- unittest now verifies more of its assumptions. In particular,
2857 TestCase and TestSuite subclasses (not instances) are no longer
2858 accepted in TestSuite.addTest(). This should cause no
2859 incompatibility since it never made sense with ordinary subclasses
2860 -- the failure just occurred later, with a more cumbersome
2861 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003148 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00003250 time so that opening a database previously created with the DB_DUP
3251 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3252 opens. Specifically: dictionary assignment to a DB object will
3253 replace all values for a given key when the database allows
3254 duplicate values. DB users should use DB.put(k, v) when they want
3255 to store duplicates; not DB[k] = v.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003535 periodic threadstate and signal checking in tight loops. By
3536 default, this option is turned-off. It should only be enabled in

Christian Heimes5b970ad2008-02-06 13:33:44 +00003594
Georg Brandl3ee81df2008-05-17 18:14:43 +00003595- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3596 to ``PyTuple_SetItem``, it can be used to populate a brand new

3609
Georg Brandl3ee81df2008-05-17 18:14:43 +00003610- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3611 of w# format code incorrectly truncated the length to an int, even
3612 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3613 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003614

3637 outside of pystate.c and should not be necessary.
3638
Georg Brandl3ee81df2008-05-17 18:14:43 +00003639- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3640 absolute imports. In earlier versions they might have used relative
3641 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003642
Georg Brandl3ee81df2008-05-17 18:14:43 +00003643- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3644 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003645
Georg Brandl3ee81df2008-05-17 18:14:43 +00003646- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003671- Removed the macfs module. It had been deprecated since Python 2.5.
3672 This lead to the deprecation of macostools.touched() as it relied
3673 solely on macfs and was a no-op under OS X.
