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.

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``
84 object also got a new readonly attribute ``closefd``.
85
Georg Brandlfa71a902008-12-05 09:08:28 +000086- Issue #3689: The list reversed iterator now supports __length_hint__

97 to wait 120 seconds for the socket to expire.
98
99- Adjusted _tkinter to compile without warnings when WITH_THREAD is not

121 guaranteed to be safe interp argument given to the PythonCmd in place of
122 the Tcl interpreter taken from a PythonCmd_ClientData.
123
124- Issue #5193: Guarantee that Tkinter.Text.search returns a string.

Hirokazu Yamamotoe363fa02009-02-28 11:39:45 +0000139- Issue #5386: mmap.write_byte didn't check map size, so it could cause buffer
140 overrun.
141

163
164- Issue #4449: AssertionError in mp_benchmarks.py, caused by an underlying issue
165 in sharedctypes.py.

201 do an explicit seek to the end of file (so that e.g. tell() returns the

203 traditional 2.x file object.

236
237- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
238 302 conformant loader) will now work correctly in most cases (they
239 are still subject to the constraints that exist for all code running
240 from inside a module loaded via a PEP 302 loader and attempting to
241 perform IO operations based on __file__). Original patch by

283
Benjamin Peterson866eba92008-11-19 22:05:53 +0000284- Issue #4348: Some bytearray methods returned that didn't cause any change to

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000571- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

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

Antoine Pitrou0668c622008-08-26 22:42:08 +0000597 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
598 mechanism. In the process, fix a bug where isinstance() and issubclass(),

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

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000740What's New in Python 2.6 beta 3?
741================================
742
Barry Warsaw07a4a382008-08-21 01:15:08 +0000743*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000744
745Core and Builtins
746-----------------
747
Guido van Rossumf8402962008-08-20 15:01:50 +0000748- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
749 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
750 extensions do not automatically benefit from the class attribute
751 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
752 to their tp_flags field if they care. This is a backwards
753 compatibility feature; in 3.0, all types will use the cache by
754 default.
755
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000756- Keyword arguments can now follow starred arguments. (``f(a, *args,
757 keyword=23)`` is now valid syntax.)
758
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000759- ctypes function pointers that are COM methods have a boolean True
760 value again.
761
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000762- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
763 by denying s# to parse objects that have a releasebuffer procedure,
764 and introducing s*.
765
Georg Brandl1e13ea92008-08-11 09:07:59 +0000766- Issue #3537: Fix an assertion failure when an empty but presized dict
767 object was stored in the freelist.
768
Mark Dickinsonb6467572008-08-04 21:30:09 +0000769- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
770 ValueError consistently across platforms.
771
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000772- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
773 (64bit Unix, for example), unichr() would truncate its argument and return
774 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
775
Neal Norwitze7d8be82008-07-31 17:17:14 +0000776- Apply security patches from Apple.
777
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000778- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
779 PyErr_ExceptionMatches returns 0 when an exception occurs there.
780
Antoine Pitrou92f82162008-07-25 22:22:08 +0000781- Issue #1819: function calls with several named parameters are now on
782 average 35% faster (as measured by pybench).
783
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000784- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
785 the python debugger steps into a class statement: the free variables (local
786 variables defined in an outer scope) would be deleted from the outer scope.
787
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000788- Issue #2620: Overflow checking when allocating or reallocating memory
789 was not always being done properly in some python types and extension
790 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
791 all been updated to perform better checks and places in the code that
792 would previously leak memory on the error path when such an allocation
793 failed have been fixed.
794
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000795Library
796-------
797

802
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000803- Issue #2234: distutils failed for some versions of the cygwin compiler. The
804 version reported by these tools does not necessarily follow the python
805 version numbering scheme, so the module is less strict when parsing it.
806
Nick Coghlanf70385a2008-08-18 12:42:46 +0000807- Issue #2235: Added Py3k warnings for types which will become unhashable
808 under the stricter __hash__ inheritance rules in 3.0. Several types
809 which did not meet the rules for hash invariants and were already
810 unhashable in 3.0 have now been explicitly flagged as unhashable in
811 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
812 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
813
Brett Cannon88f801d2008-08-18 00:46:22 +0000814- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

822
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000823- Issue #3575: Incremental decoder's decode function now takes bytearray
824 by using 's*' instead of 't#'.
825
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000826- Issue #2222: Fixed reference leak when occured os.rename()
827 fails unicode conversion on 2nd parameter. (windows only)
828
Facundo Batista94f243a2008-08-17 03:38:39 +0000829- Issue 2464. urllib2 now supports a malformation in the URL received
830 in a redirect.
831
Brett Cannonabe423e2008-08-16 21:47:07 +0000832- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000833 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000834
Facundo Batistaeb90b782008-08-16 14:44:07 +0000835- Issue #2776: fixed small issue when handling an URL with double slash
836 after a 302 response in the case of not going through a proxy.
837
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000838- Issue #2676: in the email package, content-type parsing was hanging on
839 pathological input because of quadratic or exponential behaviour of a
840 regular expression.
841
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000842- Issue #3476: binary buffered reading through the new "io" library is now
843 thread-safe.
844
Brett Cannonbf3157b2008-08-14 05:00:03 +0000845- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
846 since mimetools itself is deprecated. Because modules are cached, all
847 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
848
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000849- Issue #3134: shutil referenced undefined WindowsError symbol.
850
Robert Schuppenies14646332008-08-10 11:01:53 +0000851- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
852 menu entries were not deleted.
853
Brett Cannon83e81842008-08-09 23:30:55 +0000854- Copied the implementation of reduce() to _functools.reduce() to have a
855 version that did not raise a DeprecationWarning under -3.
856
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000857- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
858 a MemoryError rather than silently stop the iteration.
859
Guido van Rossum59ce9012008-08-09 14:55:34 +0000860- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
861 to _sre.compile() will now be rejected. This should not affect anybody
862 since the re.compile() function never generates invalid re-bytecode.
863
Skip Montanaroa032bf42008-08-08 22:52:51 +0000864- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
865 upon first access it can be automatically initialized from the csv file if
866 it wasn't initialized during instantiation.
867
Brett Cannon3aa2a492008-08-06 22:28:09 +0000868- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
869 the reload() built-in has been removed.

910 file name rather than a ZipInfo instance, so files are extracted with
911 mode 0600 rather than 000 under Unix.
912
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000913- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
914 argument in python 2.5, this broke code that subclassed Popen to include its
915 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Georg Brandl3e483f62008-07-16 22:57:41 +0000942- Issue #3156: Fix inconsistent behavior of the bytearray type: all
943 its methods now allow for items objects that can be converted to
944 an integer using operator.index().
945
Mark Dickinson64b7e502008-07-16 09:40:03 +0000946- Issue #3360: Fix incorrect parsing of '020000000000.0', which
947 produced a ValueError instead of giving the correct float.
948
Eric Smitha5fa5a22008-07-16 00:11:49 +0000949- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
950 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
951
Mark Dickinson7103aa42008-07-15 19:08:33 +0000952- Issue #3008: the float type has a new instance method 'float.hex'
953 and a new class method 'float.fromhex' to convert floating-point
954 numbers to and from hexadecimal strings, respectively.
955
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000956- Issue #2235: __hash__ is once again inherited by default. To allow
957 collections.Hashable to remain meaningful in the presence of the
958 default hash implementation (object.__hash__), it is now possible
959 to explicit block inheritance of hash by setting __hash__=None at
960 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
961 level.
962
Nick Coghlanb028f502008-07-13 14:52:36 +0000963- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
964 the parent module cannot be found while performing an absolute import.
965 This means that an incorrectly defined __package__ attribute will
966 now only prevent relative imports in that module rather than causing
967 all imports from that module to fail.
968
Nick Coghlan14ff9942008-07-08 14:21:42 +0000969- Issue #2517: Allow unicode messages in Exceptions again by correctly
970 bypassing the instance dictionary when looking up __unicode__ on
971 new-style classes.
972

974 set to a custom object whose write() method happens to install
975 another file in sys.stdout.
976
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000977- Issue #3088: Corrected a race condition in classes derived from
978 threading.local: the first member set by a thread could be saved in
979 another thread's dictionary.
980
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000981- Issue #3004: Minor change to slice.indices(): the start and stop
982 arguments are now treated identically, making the behaviour easier
983 to describe and understand. For example, slice(None, -10,
984 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
985 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
986 10, -1).
987
Georg Brandl278fc502008-07-19 12:46:12 +0000988- Issue #3219: Calling a function with repeated keyword arguments,
989 f(a=2, a=23), would not cause a syntax error. This was a regression
990 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000991
Georg Brandl278fc502008-07-19 12:46:12 +0000992- Issue #2862: Make int and float freelist management consistent with
993 other freelists. Changes their CompactFreeList apis into
994 ClearFreeList apis and calls them via gc.collect().

998
Thomas Heller57adf222008-08-14 19:10:48 +0000999- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1000 api functions without holding the GIL, which could lead to a fatal
1001 error when they failed.
1002
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001003- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1012 ForkingPickler.register() to resolve conflict with ctypes.
1013
Vinay Sajip51e65192008-07-18 09:01:10 +00001014- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001015
Thomas Heller880f5292008-07-15 19:39:38 +00001016- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1017 a valid dlerror() message.

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001027
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001028- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1029 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001030 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001031 content-length. The problem had been corrected in the 2.4 branch, but never
1032 merged into trunk.
1033
Georg Brandle78fbcc2008-07-05 10:13:36 +00001034- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001047- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1048 handling is now the same as that of other special attributes like __name__).
1049
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001050- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00001502- Issue #1631171: Re-implement the 'warnings' module in C (the
1503 original Python code has been kept as backup). This will allow for
1504 using the 'warning's machinery in such places as the parser where
1505 use of pure Python code is not possible. Both the ``showarning()``
1506 and ``formatwarning()`` gain an optional 'line' argument which is
1507 not called by default for backwards-compatibility reasons. Setting
1508 ``warnings.showwarning()`` to an implementation that lacks support
1509 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001572- Issue #2550: The approach used by client/server code for obtaining
1573 ports to listen on in network-oriented tests has been refined in an
1574 effort to facilitate running multiple instances of the entire
1575 regression test suite in parallel without issue.
1576 test_support.bind_port() has been fixed such that it will always
1577 return a unique port -- which wasn't always the case with the
1578 previous implementation, especially if socket options had been set
1579 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1580 new implementation of bind_port() will actually raise an exception
1581 if it is passed an AF_INET/SOCK_STREAM socket with either the
1582 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1583 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1584 the socket it's been passed. This currently only applies to
1585 Windows. This option prevents any other sockets from binding to the
1586 host/port we've bound to, thus removing the possibility of the
1587 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1588 when a second SOCK_STREAM socket binds and accepts to a host/port
1589 that's already been bound by another socket. The optional preferred
1590 port parameter to bind_port() has been removed. Under no
1591 circumstances should tests be hard coding ports!
1592
1593 test_support.find_unused_port() has also been introduced, which will
1594 pass a temporary socket object to bind_port() in order to obtain an
1595 unused port. The temporary socket object is then closed and
1596 deleted, and the port is returned. This method should only be used
1597 for obtaining an unused port in order to pass to an external program
1598 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1599 a parameter to a server-oriented class that doesn't give you direct
1600 access to the underlying socket used.
1601
1602 Finally, test_support.HOST has been introduced, which should be used
1603 for the host argument of any relevant socket calls (i.e. bind and
1604 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001605
1606 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001607 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001608 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1609 test_asynchat and test_socket_ssl.
1610
Georg Brandl3ee81df2008-05-17 18:14:43 +00001611 It is now possible for multiple instances of the regression test
1612 suite to run in parallel without issue.

1879-----------------
1880
Fred Drakea8ee94b2008-03-01 02:45:07 +00001881- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001882 644. The mode is now inherited from the py file.

1885
1886- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001887
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001888- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001889 issue 215555 for a discussion.
1890
Eric Smitha73fbe72008-02-23 03:09:44 +00001891- Added the future_builtins module, which contains hex() and oct().
1892 These are the PEP 3127 version of these functions, designed to be
1893 compatible with the hex() and oct() builtins from Python 3.0. They
1894 differ slightly in their output formats from the existing, unchanged
1895 Python 2.6 builtins. The expected usage of the future_builtins
1896 module is:
1897 from future_builtins import hex, oct
1898
Eric Smith7ef40bf2008-02-20 23:34:22 +00001899- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1900 exponents for exponents with absolute value < 100. Follows C99
1901 standard. This is a change on Windows, which would use 3 digits.
1902 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1903 so that any alterations it does to the resulting string will be
1904 available in stringlib/formatter.h (for float.__format__).
1905
Eric Smith5a3c1352008-02-19 13:21:56 +00001906- Implemented PEP 3101, Advanced String Formatting. This adds a new
1907 builtin format(); a format() method for str and unicode; a
1908 __format__() method to object, str, unicode, int, long, float, and
1909 datetime; the class string.Formatter; and the C API
1910 PyObject_Format().
1911
Georg Brandl3ee81df2008-05-17 18:14:43 +00001912- Fixed several potential crashes, all caused by specially crafted
1913 __del__ methods exploiting objects in temporarily inconsistent
1914 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001915
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001916- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001917 prevent a possible crash: an Abstract Base Class would try to access
1918 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001919
Georg Brandl3ee81df2008-05-17 18:14:43 +00001920- Fixed repr() and str() of complex numbers with infinity or nan as
1921 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001922
Georg Brandl3ee81df2008-05-17 18:14:43 +00001923- Clear all free lists during a gc.collect() of the highest generation
1924 in order to allow pymalloc to free more arenas. Python may give back
1925 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001926
Georg Brandl3ee81df2008-05-17 18:14:43 +00001927- Issue #2045: Fix an infinite recursion triggered when printing a
1928 subclass of collections.defaultdict, if its default_factory is set
1929 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001930
Christian Heimesf75dbef2008-02-08 00:11:31 +00001931- Fixed a minor memory leak in dictobject.c. The content of the free
1932 list was not freed on interpreter shutdown.
1933
Georg Brandl3ee81df2008-05-17 18:14:43 +00001934- Limit free list of method and builtin function objects to 256
1935 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001936
Georg Brandl3ee81df2008-05-17 18:14:43 +00001937- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1938 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001939 to compact the internal free lists of pre-allocted ints and floats.
1940
Georg Brandl3ee81df2008-05-17 18:14:43 +00001941- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1942 calls. Python expected the return type int but the fork familie
1943 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001944
Georg Brandl3ee81df2008-05-17 18:14:43 +00001945- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1946 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001947
Georg Brandl3ee81df2008-05-17 18:14:43 +00001948- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1949 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001950

1952 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00001953
Georg Brandl3ee81df2008-05-17 18:14:43 +00001954- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1955 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001956
Georg Brandl3ee81df2008-05-17 18:14:43 +00001957- Patch #1473257: generator objects gain a gi_code attribute. This is
1958 the same object as the func_code attribute of the function that
1959 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001960
Georg Brandl3ee81df2008-05-17 18:14:43 +00001961- Issue #1920: "while 0" statements were completely removed by the
1962 compiler, even in the presence of an "else" clause, which is
1963 supposed to be run when the condition is false. Now the compiler
1964 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001965
Guido van Rossumeead05f2008-01-24 18:21:02 +00001966- A few crashers fixed: weakref_in_del.py (issue #1377858);
1967 loosing_dict_ref.py (issue #1303614, test67.py);
1968 borrowed_ref_[34].py (not in tracker).
1969
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001970- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001971 suppressed while an extension is loaded by calling SetErrorMode in
1972 dynload_win.c. The error is still reported properly.
1973
Georg Brandl3ee81df2008-05-17 18:14:43 +00001974- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001975 several extension methods and modules do not work without unicode
1976 support.
1977
Georg Brandl26543b12008-01-21 18:36:51 +00001978- Issue #1882: when compiling code from a string, encoding cookies in the
1979 second line of code were not always recognized correctly.
1980
Georg Brandl14404b62008-01-19 19:27:05 +00001981- Issue #1679: "0x" was taken as a valid integer literal.
1982
Georg Brandl6caad7d2008-01-26 14:19:22 +00001983- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001984 added.
1985
Christian Heimesc94e2b52008-01-14 04:13:37 +00001986- sys.float_info / PyFloat_GetInfo: The floating point information
1987 object was converted from a dict to a specialized structseq object.
1988
Georg Brandl3ee81df2008-05-17 18:14:43 +00001989- Patch #1816: Added sys.flags structseq. It exposes the status of
1990 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001991
Georg Brandl3ee81df2008-05-17 18:14:43 +00001992- Objects/structseq.c: Implemented new structseq representation. The
1993 patch makes structseqs (e.g. the return value of os.stat) more
1994 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001995
Georg Brandl3ee81df2008-05-17 18:14:43 +00001996- Patch #1700288: added a type attribute cache that caches method
1997 accesses, resulting in speedups in heavily object-oriented code.

2006 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002007
Georg Brandl3ee81df2008-05-17 18:14:43 +00002008- Improve some exception messages when Windows fails to load an
2009 extension module. Now we get for example '%1 is not a valid Win32
2010 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002011

Georg Brandl3ee81df2008-05-17 18:14:43 +00002021- Compiler now generates simpler and faster code for dictionary
2022 literals. The oparg for BUILD_MAP now indicates an estimated
2023 dictionary size. There is a new opcode, STORE_MAP, for adding
2024 entries to the dictionary.

2067
Georg Brandl3ee81df2008-05-17 18:14:43 +00002068- The enumerate() builtin function is no longer bounded to sequences
2069 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2070 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002071
Georg Brandl3ee81df2008-05-17 18:14:43 +00002072- Issue #1686386: Tuple's tp_repr did not take into account the
2073 possibility of having a self-referential tuple, which is possible
2074 from C code. Nor did object's tp_str consider that a type's tp_str
2075 could do something that could lead to an inifinite recursion.
2076 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2077 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002078
Georg Brandl3ee81df2008-05-17 18:14:43 +00002079- Issue #1164: It was possible to trigger deadlock when using the
2080 'print' statement to write to a file since the GIL was not released
2081 as needed. Now PyObject_Print() does the right thing along with
2082 various tp_print implementations of the built-in types and those in
2083 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00002092- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002093 PyObject_Call() never calling back out to Python code to trigger
2094 recursion depth updates/checks. Required the creation of a static

Neal Norwitz0ac60192007-05-27 04:08:54 +00002112- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002113 __*__ attributes. (Some already existed, e.g., __doc__ and
2114 __name__.)

2120 calls.
2121
Collin Winter62903052007-05-18 23:11:24 +00002122- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002123 "except E as target:". This is to provide forwards compatibility
2124 with Python 3.0.

2130
Vinay Sajip8549ce32007-05-06 17:53:37 +00002131- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002132 setting a plain string, ie don't expand to single letter identifiers.
2133
Raymond Hettinger13936692007-04-11 18:40:58 +00002134- Request #1191699: Slices can now be pickled.
2135
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002136- Request #1193128: str.translate() now allows a None argument for

2138 remaining characters.
2139
Georg Brandl5cb76c12007-03-21 09:00:39 +00002140- Patch #1682205: a TypeError while unpacking an iterable is no longer

2144
Guido van Rossum143b5642007-03-23 04:58:42 +00002145- Bug #1683368: The object.__init__() and object.__new__() methods are
2146 now stricter in rejecting excess arguments. The only time when
2147 either allows excess arguments is when it is not overridden and the
2148 other one is. For backwards compatibility, when both are
2149 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002150 warning later). Also, type.__init__() insists on the same signature
2151 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002152
Georg Brandl3ee81df2008-05-17 18:14:43 +00002153- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2154 object to complex using its __complex__() method before falling back
2155 to the __float__() method. Therefore, the functions in the cmath
2156 module now can operate on objects that define a __complex__()
2157 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002158
Georg Brandl3ee81df2008-05-17 18:14:43 +00002159- Patch #1623563: allow __class__ assignment for classes with
2160 __slots__. The old and the new class are still required to have the
2161 same slot names.

2168 its type.

2174
Georg Brandl7b9c5552007-03-12 14:30:05 +00002175- Bug #1678647: write a newline after printing an exception in any
2176 case, even when converting the value to a string failed.
2177
Georg Brandl871f1bc2007-03-12 13:17:36 +00002178- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002179 its argument, if it exists. If not, it will work like before. This
2180 allows customizing the output of dir() in the presence of a
2181 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002182
Collin Winter276887b2007-03-12 16:11:39 +00002183- Patch #922167: Python no longer segfaults when faced with infinitely
2184 self-recursive reload() calls (as reported by bug #742342).
2185
Georg Brandl3ee81df2008-05-17 18:14:43 +00002186- Patch #1675981: remove unreachable code from ``type.__new__()``

2190 parthensized forms. This means complex(repr(x)) now works instead of
2191 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002192
Georg Brandlaa2321b2007-03-07 00:40:28 +00002193- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002194 makes the filenames the warning module prints much more sensible
2195 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002196

Georg Brandl0fca97a2007-03-05 22:28:08 +00002208- Patch #1674228: when assigning a slice (old-style), check for the
2209 sq_ass_slice instead of the sq_slice slot.
2210
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- When printing an unraisable error, don't print exceptions. before
2212 the name. This duplicates the behavior whening normally printing
2213 exceptions.

Guido van Rossum8bc09652008-02-21 18:18:37 +00002355- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00002746 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00002748

Georg Brandl3ee81df2008-05-17 18:14:43 +00002764- Patch #1530482: add pydoc.render_doc() which returns the

2779
Georg Brandl92a6bae2007-03-13 17:43:32 +00002780- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00002781 are set for invalid interpolation sequences that would lead to
2782 errors on reading back those values.

2838 TestCase and TestSuite subclasses (not instances) are no longer
2839 accepted in TestSuite.addTest(). This should cause no
2840 incompatibility since it never made sense with ordinary subclasses
2841 -- the failure just occurred later, with a more cumbersome
2842 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003129 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003230- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231 time so that opening a database previously created with the DB_DUP
3232 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3233 opens. Specifically: dictionary assignment to a DB object will
3234 replace all values for a given key when the database allows
3235 duplicate values. DB users should use DB.put(k, v) when they want
3236 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003515- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00003516 periodic threadstate and signal checking in tight loops. By
3517 default, this option is turned-off. It should only be enabled in
3518 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00003575
Georg Brandl3ee81df2008-05-17 18:14:43 +00003576- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3577 to ``PyTuple_SetItem``, it can be used to populate a brand new

3590
Georg Brandl3ee81df2008-05-17 18:14:43 +00003591- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3592 of w# format code incorrectly truncated the length to an int, even
3593 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3594 incorrect results with huge strings.

3622 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003623
Georg Brandl3ee81df2008-05-17 18:14:43 +00003624- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3625 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003626

Georg Brandl3ee81df2008-05-17 18:14:43 +00003652- Removed the macfs module. It had been deprecated since Python 2.5.
3653 This lead to the deprecation of macostools.touched() as it relied
