Vinay Sajip6badbe92009-01-20 22:49:13 +000078- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +000079 method on file objects with closefd=False. The file descriptor is still

153 do an explicit seek to the end of file (so that e.g. tell() returns the
154 file size rather than 0). This is consistent with the behaviour of the
155 traditional 2.x file object.

186 zipimport (or any other conformant PEP 302 loader). Original patch by
187 Alexander Belopolsky.
188
189- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
190 302 conformant loader) will now work correctly in most cases (they
191 are still subject to the constraints that exist for all code running
192 from inside a module loaded via a PEP 302 loader and attempting to
193 perform IO operations based on __file__). Original patch by
194 Alexander Belopolsky.
195

235
Benjamin Peterson866eba92008-11-19 22:05:53 +0000236- Issue #4348: Some bytearray methods returned that didn't cause any change to

522
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000523- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
524 PyString_FromFormat or PyErr_Format to display size_t values. The macro
525 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
526 ``printf`` function, whereas PyString_FromFormat has an independent
527 implementation and uses "%zd" on all platforms for size_t values.
528 This makes a difference on win64, where ``printf`` needs "%Id" to display
529 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000549 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
550 mechanism. In the process, fix a bug where isinstance() and issubclass(),

646-----------------
647
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000648- Issue #2975: When compiling several extension modules with Visual Studio 2008
649 from the same python interpreter, some environment variables would grow
650 without limit.
651
Benjamin Peterson37346b22008-08-23 20:27:43 +0000652- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

659
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000660- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000689What's New in Python 2.6 beta 3?
690================================
691
Barry Warsaw07a4a382008-08-21 01:15:08 +0000692*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000693
694Core and Builtins
695-----------------
696
Guido van Rossumf8402962008-08-20 15:01:50 +0000697- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
698 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
699 extensions do not automatically benefit from the class attribute
700 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
701 to their tp_flags field if they care. This is a backwards
702 compatibility feature; in 3.0, all types will use the cache by
703 default.
704
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000705- Keyword arguments can now follow starred arguments. (``f(a, *args,
706 keyword=23)`` is now valid syntax.)
707
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000708- ctypes function pointers that are COM methods have a boolean True
709 value again.
710
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000711- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
712 by denying s# to parse objects that have a releasebuffer procedure,
713 and introducing s*.
714
Georg Brandl1e13ea92008-08-11 09:07:59 +0000715- Issue #3537: Fix an assertion failure when an empty but presized dict
716 object was stored in the freelist.
717
Mark Dickinsonb6467572008-08-04 21:30:09 +0000718- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
719 ValueError consistently across platforms.
720
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000721- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
722 (64bit Unix, for example), unichr() would truncate its argument and return
723 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
724
Neal Norwitze7d8be82008-07-31 17:17:14 +0000725- Apply security patches from Apple.
726
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000727- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
728 PyErr_ExceptionMatches returns 0 when an exception occurs there.
729
Antoine Pitrou92f82162008-07-25 22:22:08 +0000730- Issue #1819: function calls with several named parameters are now on
731 average 35% faster (as measured by pybench).
732
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000733- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
734 the python debugger steps into a class statement: the free variables (local
735 variables defined in an outer scope) would be deleted from the outer scope.
736
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000737- Issue #2620: Overflow checking when allocating or reallocating memory
738 was not always being done properly in some python types and extension
739 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
740 all been updated to perform better checks and places in the code that
741 would previously leak memory on the error path when such an allocation
742 failed have been fixed.
743
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000744Library
745-------
746
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +0000747- Issue #3612: Added some missing basic types in ctypes.wintypes.
748
Benjamin Petersone977ad42008-08-20 01:42:01 +0000749- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
750 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
751
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000752- Issue #2234: distutils failed for some versions of the cygwin compiler. The
753 version reported by these tools does not necessarily follow the python
754 version numbering scheme, so the module is less strict when parsing it.
755
Nick Coghlanf70385a2008-08-18 12:42:46 +0000756- Issue #2235: Added Py3k warnings for types which will become unhashable
757 under the stricter __hash__ inheritance rules in 3.0. Several types
758 which did not meet the rules for hash invariants and were already
759 unhashable in 3.0 have now been explicitly flagged as unhashable in
760 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
761 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
762
Brett Cannon88f801d2008-08-18 00:46:22 +0000763- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

769
Brett Cannon25c9d6a2008-08-17 22:10:11 +0000770- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
771
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000772- Issue #3575: Incremental decoder's decode function now takes bytearray
773 by using 's*' instead of 't#'.
774
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000775- Issue #2222: Fixed reference leak when occured os.rename()
776 fails unicode conversion on 2nd parameter. (windows only)
777
Facundo Batista94f243a2008-08-17 03:38:39 +0000778- Issue 2464. urllib2 now supports a malformation in the URL received
779 in a redirect.
780
Brett Cannonabe423e2008-08-16 21:47:07 +0000781- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000782 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000783
Facundo Batistaeb90b782008-08-16 14:44:07 +0000784- Issue #2776: fixed small issue when handling an URL with double slash
785 after a 302 response in the case of not going through a proxy.
786
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000787- Issue #2676: in the email package, content-type parsing was hanging on
788 pathological input because of quadratic or exponential behaviour of a
789 regular expression.
790
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000791- Issue #3476: binary buffered reading through the new "io" library is now
792 thread-safe.
793
Brett Cannonbf3157b2008-08-14 05:00:03 +0000794- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
795 since mimetools itself is deprecated. Because modules are cached, all
796 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
797
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000798- Issue #3134: shutil referenced undefined WindowsError symbol.
799
Robert Schuppenies14646332008-08-10 11:01:53 +0000800- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
801 menu entries were not deleted.
802
Brett Cannon83e81842008-08-09 23:30:55 +0000803- Copied the implementation of reduce() to _functools.reduce() to have a
804 version that did not raise a DeprecationWarning under -3.
805
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000806- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
807 a MemoryError rather than silently stop the iteration.
808
Guido van Rossum59ce9012008-08-09 14:55:34 +0000809- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
810 to _sre.compile() will now be rejected. This should not affect anybody
811 since the re.compile() function never generates invalid re-bytecode.
812
Skip Montanaroa032bf42008-08-08 22:52:51 +0000813- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
814 upon first access it can be automatically initialized from the csv file if
815 it wasn't initialized during instantiation.
816
Brett Cannon3aa2a492008-08-06 22:28:09 +0000817- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
818 the reload() built-in has been removed.
819
Brett Cannon7e30b672008-08-04 21:52:25 +0000820- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000821 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +0000822 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
823 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
824 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
825 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
826 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +0000827
Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000828- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
829 raised an AttributeError.
830
Benjamin Peterson01a24322008-07-28 23:35:27 +0000831- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000832 asking for a specific length. This problem only affected files opened
833 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000834

839
Raymond Hettinger8c664e82008-07-25 18:43:33 +0000840- Issue 1592: Improve error reporting when operations are attempted

842
Georg Brandlf9efabb2008-07-23 15:16:45 +0000843- Deprecate the "ast" parser function aliases.
844
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000845- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.

854 configuration files.
855
856- Deprecate the sunaudio module for removal in Python 3.0.
857
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000858- Issue #3394: zipfile.writestr sets external attributes when passed a
859 file name rather than a ZipInfo instance, so files are extracted with
860 mode 0600 rather than 000 under Unix.
861
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000862- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
863 argument in python 2.5, this broke code that subclassed Popen to include its
864 own poll method. Fixed my moving _deadstate to an _internal_poll method.
865
Martin v. Löwis8dbf3642008-08-01 14:10:26 +0000866Build

872-------------
873
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000874- Issue #2235: the C API function PyObject_HashNotImplemented and its
875 interaction with the tp_hash slot (added in 2.6b2) are now documented
876
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000877- Issue #643841: The language reference now provides more detailed
878 coverage of the lookup process for special methods. The disclaimers
879 regarding lack of coverage of new-style classes have also been
880 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000883What's New in Python 2.6 beta 2?
884================================
885
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000886*Release date: 17-Jul-2008*
887
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000888Core and Builtins
889-----------------
890
Georg Brandl3e483f62008-07-16 22:57:41 +0000891- Issue #3156: Fix inconsistent behavior of the bytearray type: all
892 its methods now allow for items objects that can be converted to
893 an integer using operator.index().
894
Mark Dickinson64b7e502008-07-16 09:40:03 +0000895- Issue #3360: Fix incorrect parsing of '020000000000.0', which
896 produced a ValueError instead of giving the correct float.
897
Eric Smitha5fa5a22008-07-16 00:11:49 +0000898- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
899 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
900
Mark Dickinson7103aa42008-07-15 19:08:33 +0000901- Issue #3008: the float type has a new instance method 'float.hex'
902 and a new class method 'float.fromhex' to convert floating-point
903 numbers to and from hexadecimal strings, respectively.
904
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000905- Issue #2235: __hash__ is once again inherited by default. To allow
906 collections.Hashable to remain meaningful in the presence of the
907 default hash implementation (object.__hash__), it is now possible
908 to explicit block inheritance of hash by setting __hash__=None at
909 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
910 level.
911
Nick Coghlanb028f502008-07-13 14:52:36 +0000912- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
913 the parent module cannot be found while performing an absolute import.
914 This means that an incorrectly defined __package__ attribute will
915 now only prevent relative imports in that module rather than causing
916 all imports from that module to fail.
917
Nick Coghlan14ff9942008-07-08 14:21:42 +0000918- Issue #2517: Allow unicode messages in Exceptions again by correctly
919 bypassing the instance dictionary when looking up __unicode__ on
920 new-style classes.
921
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000922- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
923 set to a custom object whose write() method happens to install
924 another file in sys.stdout.
925
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000926- Issue #3088: Corrected a race condition in classes derived from
927 threading.local: the first member set by a thread could be saved in
928 another thread's dictionary.
929
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000930- Issue #3004: Minor change to slice.indices(): the start and stop
931 arguments are now treated identically, making the behaviour easier
932 to describe and understand. For example, slice(None, -10,
933 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
934 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
935 10, -1).
936
Georg Brandl278fc502008-07-19 12:46:12 +0000937- Issue #3219: Calling a function with repeated keyword arguments,
938 f(a=2, a=23), would not cause a syntax error. This was a regression
939 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00001389 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001390
1391 This is controlled by the configure argument ``--with-universal-archs``:
1392

1394
1395 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1396
1397 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

1438 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00001440- Added kill, terminate and send_signal(sig) to subprocess.Popen.
1441

Georg Brandl3ee81df2008-05-17 18:14:43 +00001451- Issue #1631171: Re-implement the 'warnings' module in C (the
1452 original Python code has been kept as backup). This will allow for
1453 using the 'warning's machinery in such places as the parser where
1454 use of pure Python code is not possible. Both the ``showarning()``
1455 and ``formatwarning()`` gain an optional 'line' argument which is
1456 not called by default for backwards-compatibility reasons. Setting
1457 ``warnings.showwarning()`` to an implementation that lacks support
1458 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001483- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00001521- Issue #2550: The approach used by client/server code for obtaining
1522 ports to listen on in network-oriented tests has been refined in an
1523 effort to facilitate running multiple instances of the entire
1524 regression test suite in parallel without issue.
1525 test_support.bind_port() has been fixed such that it will always
1526 return a unique port -- which wasn't always the case with the
1527 previous implementation, especially if socket options had been set
1528 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1529 new implementation of bind_port() will actually raise an exception
1530 if it is passed an AF_INET/SOCK_STREAM socket with either the
1531 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1532 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1533 the socket it's been passed. This currently only applies to
1534 Windows. This option prevents any other sockets from binding to the
1535 host/port we've bound to, thus removing the possibility of the
1536 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1537 when a second SOCK_STREAM socket binds and accepts to a host/port
1538 that's already been bound by another socket. The optional preferred
1539 port parameter to bind_port() has been removed. Under no
1540 circumstances should tests be hard coding ports!
1541
1542 test_support.find_unused_port() has also been introduced, which will
1543 pass a temporary socket object to bind_port() in order to obtain an
1544 unused port. The temporary socket object is then closed and
1545 deleted, and the port is returned. This method should only be used
1546 for obtaining an unused port in order to pass to an external program
1547 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1548 a parameter to a server-oriented class that doesn't give you direct
1549 access to the underlying socket used.
1550
1551 Finally, test_support.HOST has been introduced, which should be used
1552 for the host argument of any relevant socket calls (i.e. bind and
1553 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001554
1555 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001556 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001557 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1558 test_asynchat and test_socket_ssl.
1559
Georg Brandl3ee81df2008-05-17 18:14:43 +00001560 It is now possible for multiple instances of the regression test
1561 suite to run in parallel without issue.

1828-----------------
1829
Fred Drakea8ee94b2008-03-01 02:45:07 +00001830- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001831 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00001833- Issue #2067: file.__exit__() now calls subclasses' close() method.
1834
1835- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001836
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001837- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001838 issue 215555 for a discussion.
1839
Eric Smitha73fbe72008-02-23 03:09:44 +00001840- Added the future_builtins module, which contains hex() and oct().
1841 These are the PEP 3127 version of these functions, designed to be
1842 compatible with the hex() and oct() builtins from Python 3.0. They
1843 differ slightly in their output formats from the existing, unchanged
1844 Python 2.6 builtins. The expected usage of the future_builtins
1845 module is:
1846 from future_builtins import hex, oct
1847
Eric Smith7ef40bf2008-02-20 23:34:22 +00001848- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1849 exponents for exponents with absolute value < 100. Follows C99
1850 standard. This is a change on Windows, which would use 3 digits.
1851 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1852 so that any alterations it does to the resulting string will be
1853 available in stringlib/formatter.h (for float.__format__).
1854
Eric Smith5a3c1352008-02-19 13:21:56 +00001855- Implemented PEP 3101, Advanced String Formatting. This adds a new
1856 builtin format(); a format() method for str and unicode; a
1857 __format__() method to object, str, unicode, int, long, float, and
1858 datetime; the class string.Formatter; and the C API
1859 PyObject_Format().
1860
Georg Brandl3ee81df2008-05-17 18:14:43 +00001861- Fixed several potential crashes, all caused by specially crafted
1862 __del__ methods exploiting objects in temporarily inconsistent
1863 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001864
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001865- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001866 prevent a possible crash: an Abstract Base Class would try to access
1867 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001868
Georg Brandl3ee81df2008-05-17 18:14:43 +00001869- Fixed repr() and str() of complex numbers with infinity or nan as
1870 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001871
Georg Brandl3ee81df2008-05-17 18:14:43 +00001872- Clear all free lists during a gc.collect() of the highest generation
1873 in order to allow pymalloc to free more arenas. Python may give back
1874 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001875
Georg Brandl3ee81df2008-05-17 18:14:43 +00001876- Issue #2045: Fix an infinite recursion triggered when printing a
1877 subclass of collections.defaultdict, if its default_factory is set
1878 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001879
Christian Heimesf75dbef2008-02-08 00:11:31 +00001880- Fixed a minor memory leak in dictobject.c. The content of the free
1881 list was not freed on interpreter shutdown.
1882
Georg Brandl3ee81df2008-05-17 18:14:43 +00001883- Limit free list of method and builtin function objects to 256
1884 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001885
Georg Brandl3ee81df2008-05-17 18:14:43 +00001886- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1887 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001888 to compact the internal free lists of pre-allocted ints and floats.
1889
Georg Brandl3ee81df2008-05-17 18:14:43 +00001890- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1891 calls. Python expected the return type int but the fork familie
1892 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001893
Georg Brandl3ee81df2008-05-17 18:14:43 +00001894- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1895 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001896

Georg Brandl3ee81df2008-05-17 18:14:43 +00001906- Patch #1473257: generator objects gain a gi_code attribute. This is
1907 the same object as the func_code attribute of the function that
1908 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001909
Georg Brandl3ee81df2008-05-17 18:14:43 +00001910- Issue #1920: "while 0" statements were completely removed by the
1911 compiler, even in the presence of an "else" clause, which is
1912 supposed to be run when the condition is false. Now the compiler
1913 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001914
Guido van Rossumeead05f2008-01-24 18:21:02 +00001915- A few crashers fixed: weakref_in_del.py (issue #1377858);
1916 loosing_dict_ref.py (issue #1303614, test67.py);
1917 borrowed_ref_[34].py (not in tracker).
1918
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001919- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001920 suppressed while an extension is loaded by calling SetErrorMode in
1921 dynload_win.c. The error is still reported properly.
1922
Georg Brandl3ee81df2008-05-17 18:14:43 +00001923- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001924 several extension methods and modules do not work without unicode
1925 support.
1926
Georg Brandl26543b12008-01-21 18:36:51 +00001927- Issue #1882: when compiling code from a string, encoding cookies in the
1928 second line of code were not always recognized correctly.
1929
Georg Brandl14404b62008-01-19 19:27:05 +00001930- Issue #1679: "0x" was taken as a valid integer literal.
1931
Georg Brandl6caad7d2008-01-26 14:19:22 +00001932- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001933 added.
1934
Christian Heimesc94e2b52008-01-14 04:13:37 +00001935- sys.float_info / PyFloat_GetInfo: The floating point information
1936 object was converted from a dict to a specialized structseq object.
1937
Georg Brandl3ee81df2008-05-17 18:14:43 +00001938- Patch #1816: Added sys.flags structseq. It exposes the status of
1939 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001940
Georg Brandl3ee81df2008-05-17 18:14:43 +00001941- Objects/structseq.c: Implemented new structseq representation. The
1942 patch makes structseqs (e.g. the return value of os.stat) more
1943 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001944
Georg Brandl3ee81df2008-05-17 18:14:43 +00001945- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00001967 and INF. float("nan"), float("inf") and float("-inf") now work on
1968 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001969
Georg Brandl3ee81df2008-05-17 18:14:43 +00001970- Compiler now generates simpler and faster code for dictionary
1971 literals. The oparg for BUILD_MAP now indicates an estimated
1972 dictionary size. There is a new opcode, STORE_MAP, for adding
1973 entries to the dictionary.

2003 file can now be directly executed by passing their name to the
2004 interpreter. The directory/zipfile is automatically inserted as the
2005 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002007- Issue #1265: Fix a problem with sys.settrace, if the tracing
2008 function uses a generator expression when at the same time the
2009 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002010
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002011- sets and frozensets now have an isdisjoint() method.
2012
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002013- optimize the performance of builtin.sum().
2014
Neal Norwitz44f326e2007-10-05 05:29:17 +00002015- Fix warnings found by the new version of the Coverity checker.
2016
Georg Brandl3ee81df2008-05-17 18:14:43 +00002017- The enumerate() builtin function is no longer bounded to sequences
2018 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2019 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002020
Georg Brandl3ee81df2008-05-17 18:14:43 +00002021- Issue #1686386: Tuple's tp_repr did not take into account the
2022 possibility of having a self-referential tuple, which is possible
2023 from C code. Nor did object's tp_str consider that a type's tp_str
2024 could do something that could lead to an inifinite recursion.
2025 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2026 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002027
Georg Brandl3ee81df2008-05-17 18:14:43 +00002028- Issue #1164: It was possible to trigger deadlock when using the
2029 'print' statement to write to a file since the GIL was not released
2030 as needed. Now PyObject_Print() does the right thing along with
2031 various tp_print implementations of the built-in types and those in
2032 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002033
Georg Brandl3ee81df2008-05-17 18:14:43 +00002034- Issue #1147: Exceptions were directly allowing string exceptions in
2035 their throw() method even though string exceptions no longer
2036 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002037
Georg Brandl3ee81df2008-05-17 18:14:43 +00002038- Issue #1096: Prevent a segfault from getting the repr of a very
2039 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002040
Brett Cannon1e534b52007-09-07 04:18:30 +00002041- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002042 PyObject_Call() never calling back out to Python code to trigger
2043 recursion depth updates/checks. Required the creation of a static
2044 RuntimeError instance in case normalizing an exception put the
2045 recursion check value past its limit. Fixes crashers
2046 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002047
Georg Brandl3ee81df2008-05-17 18:14:43 +00002048- Patch #1031213: Decode source line in SyntaxErrors back to its

2052 with %G.
2053
Georg Brandl3ee81df2008-05-17 18:14:43 +00002054- Prevent expandtabs() on string and unicode objects from causing a
2055 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002056

Neal Norwitz0ac60192007-05-27 04:08:54 +00002061- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002062 __*__ attributes. (Some already existed, e.g., __doc__ and
2063 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002064
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002065- Add -3 option to the interpreter to warn about features that are
2066 deprecated and will be changed/removed in Python 3.0.
2067
Georg Brandl2134e752007-05-21 20:34:16 +00002068- Patch #1686487: you can now pass any mapping after '**' in function
2069 calls.
2070
Collin Winter62903052007-05-18 23:11:24 +00002071- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002072 "except E as target:". This is to provide forwards compatibility
2073 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002074
Brett Cannon229cee22007-05-05 01:34:02 +00002075- Deprecate BaseException.message as per PEP 352.
2076
Georg Brandl3ee81df2008-05-17 18:14:43 +00002077- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002078 inherited from a builtin base.
2079
Vinay Sajip8549ce32007-05-06 17:53:37 +00002080- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002081 setting a plain string, ie don't expand to single letter identifiers.
2082
Raymond Hettinger13936692007-04-11 18:40:58 +00002083- Request #1191699: Slices can now be pickled.
2084
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002085- Request #1193128: str.translate() now allows a None argument for
2086 translations that only remove characters without re-mapping the
2087 remaining characters.
2088
Georg Brandl5cb76c12007-03-21 09:00:39 +00002089- Patch #1682205: a TypeError while unpacking an iterable is no longer
2090 masked by a generic one with the message "unpack non-sequence".
2091
Neal Norwitzaa754b72007-03-21 06:39:48 +00002092- Remove unused file Python/fmod.c.
2093
Guido van Rossum143b5642007-03-23 04:58:42 +00002094- Bug #1683368: The object.__init__() and object.__new__() methods are
2095 now stricter in rejecting excess arguments. The only time when
2096 either allows excess arguments is when it is not overridden and the
2097 other one is. For backwards compatibility, when both are
2098 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002099 warning later). Also, type.__init__() insists on the same signature
2100 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002101
Georg Brandl3ee81df2008-05-17 18:14:43 +00002102- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2103 object to complex using its __complex__() method before falling back
2104 to the __float__() method. Therefore, the functions in the cmath
2105 module now can operate on objects that define a __complex__()
2106 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002107
Georg Brandl3ee81df2008-05-17 18:14:43 +00002108- Patch #1623563: allow __class__ assignment for classes with
2109 __slots__. The old and the new class are still required to have the
2110 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002111
Georg Brandl3ee81df2008-05-17 18:14:43 +00002112- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002115- Patch #1462488: Python no longer segfaults when
2116 ``object.__reduce_ex__()`` is called with an object that is faking
2117 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002118
Georg Brandl3ee81df2008-05-17 18:14:43 +00002119- Patch #1680015: Don't modify __slots__ tuple if it contains an
2120 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00002122- Patch #1444529: the builtin compile() now accepts keyword arguments.
2123
Georg Brandl7b9c5552007-03-12 14:30:05 +00002124- Bug #1678647: write a newline after printing an exception in any
2125 case, even when converting the value to a string failed.
2126
Georg Brandl871f1bc2007-03-12 13:17:36 +00002127- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002128 its argument, if it exists. If not, it will work like before. This
2129 allows customizing the output of dir() in the presence of a
2130 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002131
Collin Winter276887b2007-03-12 16:11:39 +00002132- Patch #922167: Python no longer segfaults when faced with infinitely
2133 self-recursive reload() calls (as reported by bug #742342).
2134
Georg Brandl3ee81df2008-05-17 18:14:43 +00002135- Patch #1675981: remove unreachable code from ``type.__new__()``
2136 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002138- Patch #1491866: change the complex() constructor to allow
2139 parthensized forms. This means complex(repr(x)) now works instead of
2140 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002141
Georg Brandlaa2321b2007-03-07 00:40:28 +00002142- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002143 makes the filenames the warning module prints much more sensible
2144 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002145
Georg Brandl49aafc92007-03-07 00:34:46 +00002146- Variant of patch #697613: don't exit the interpreter on a SystemExit
2147 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148 variable is given, but break into the interactive interpreter just
2149 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00002150
Georg Brandl3ee81df2008-05-17 18:14:43 +00002151- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002154- Bug #1674503: close the file opened by execfile() in an error
2155 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002156
Georg Brandl0fca97a2007-03-05 22:28:08 +00002157- Patch #1674228: when assigning a slice (old-style), check for the
2158 sq_ass_slice instead of the sq_slice slot.
2159
Georg Brandl3ee81df2008-05-17 18:14:43 +00002160- When printing an unraisable error, don't print exceptions. before
2161 the name. This duplicates the behavior whening normally printing
2162 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002163
Georg Brandl3ee81df2008-05-17 18:14:43 +00002164- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Bug #1377858: Fix the segfaulting of the interpreter when an object
2171 created a weakref on itself during a __del__ call for new-style
2172 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00002173
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00002174- Bug #1579370: Make PyTraceBack_Here use the current thread, not the

Georg Brandl2c1375c2006-10-12 11:27:59 +00002212- Bug #1545497: when given an explicit base, int() did ignore NULs
2213 embedded in the string to convert.
2214
Georg Brandl846f73a2006-10-08 07:11:54 +00002215- Bug #1569998: break inside a try statement (outside a loop) is now
2216 recognized and rejected.

2219
Armin Rigo7ccbca92006-10-04 12:17:45 +00002220- A number of places, including integer negation and absolute value,
2221 were fixed to not rely on undefined behaviour of the C compiler
2222 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00002223
Georg Brandl3267d282006-09-30 09:03:42 +00002224- Bug #1566800: make sure that EnvironmentError can be called with any
2225 number of arguments, as was the case in Python 2.4.
2226
Georg Brandl5d59c092006-09-30 08:43:30 +00002227- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00002228 keyword arguments any more (previously they accepted them, but
2229 didn't use them).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002231- Fix a bug in the parser's future statement handling that led to
2232 "with" not being recognized as a keyword after, e.g., this
2233 statement: from __future__ import division, with_statement

2791 exception.

3005
Georg Brandl3ee81df2008-05-17 18:14:43 +00003006- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003072- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3073 with RFC 3207 and forgets any knowledge obtained from the server not
3074 obtained from the TLS negotiation itself. Patch contributed by Bill
3075 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003076
Georg Brandl3ee81df2008-05-17 18:14:43 +00003077- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003078 that the SMTP.starttls() caller no longer needs to call ehlo()
3079 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003080 does not claim to support starttls. Adds the
3081 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3162 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3163 silently miscode subclasses of those types. Now, it raises a
3164 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003165

Georg Brandl3ee81df2008-05-17 18:14:43 +00003180 time so that opening a database previously created with the DB_DUP
3181 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3182 opens. Specifically: dictionary assignment to a DB object will
3183 replace all values for a given key when the database allows
3184 duplicate values. DB users should use DB.put(k, v) when they want
3185 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003186

3192 characters with ASCII value less than 32. Also, it correctly quotes
3193 dots only if they occur on a single line, as opposed to the previous
3194 behavior of quoting dots if they are the second character of any
3195 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003196

3519
Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Unified naming convention for free lists and their limits. All free
3521 lists in Object/ are named ``free_list``, the counter ``numfree``
3522 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3523 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3526 to ``PyTuple_SetItem``, it can be used to populate a brand new
3527 frozenset; but it does not steal a reference to the added item.

3539
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3541 of w# format code incorrectly truncated the length to an int, even
3542 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3543 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003544
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3563- Fix some leftovers from the conversion from int to Py_ssize_t
3564 (relevant to strings and sequences of more than 2**31 items).
3565
3566- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3567 outside of pystate.c and should not be necessary.
3568
Georg Brandl3ee81df2008-05-17 18:14:43 +00003569- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3570 absolute imports. In earlier versions they might have used relative
3571 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003572
Georg Brandl3ee81df2008-05-17 18:14:43 +00003573- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3574 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003575
Georg Brandl3ee81df2008-05-17 18:14:43 +00003576- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

3584 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3585 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3586 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003587

Georg Brandl3ee81df2008-05-17 18:14:43 +00003601- Removed the macfs module. It had been deprecated since Python 2.5.
3602 This lead to the deprecation of macostools.touched() as it relied
3603 solely on macfs and was a no-op under OS X.
