19 were suppressing all exceptions. These include list(), filter(), map(),
20 zip(), and bytearray().
21
Antoine Pitroua1b22ce2009-01-13 23:25:47 +000022- Issue #4935: The overflow checking code in the expandtabs() method common
23 to str, bytes and bytearray could be optimized away by the compiler, letting

29 an existing .py counterpart, override the co_filename attributes of all
30 code objects if the original filename is obsolete (which can happen if the
31 file has been renamed, moved, or if it is accessed through different paths).
32 Patch by Ziga Seilnacht and Jean-Paul Calderone.
33
Georg Brandl734373c2009-01-03 21:55:17 +000034- Issue #4075: Use OutputDebugStringW in Py_FatalError.

40 did not get collected.
41
Nick Coghland4656402008-12-30 01:36:00 +000042- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
43 where the tp_hash and tp_dict slots are both NULL.
44
Georg Brandl47fe9812009-01-01 15:46:10 +000045- Issue #4764: With io.open, IOError.filename is set when trying to open a

60 exceptions.
61
Benjamin Petersonc6e80eb2008-12-21 17:01:26 +000062- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

68
Vinay Sajip6badbe92009-01-20 22:49:13 +000069- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +000070 method on file objects with closefd=False. The file descriptor is still

104 inside its source path if it began with the same letters (e.g. "src" vs.
105 "src.new").
106
Raymond Hettingerc9794482009-01-28 23:14:58 +0000107- Issue 4920: Fixed .next() vs .__next__() issues in the ABCs for

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

135 did unnecessary work in the common case where no key function was specified.

155
156- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
157 302 conformant loader) will now work correctly in most cases (they
158 are still subject to the constraints that exist for all code running
159 from inside a module loaded via a PEP 302 loader and attempting to
160 perform IO operations based on __file__). Original patch by

484
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000485- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
486 PyString_FromFormat or PyErr_Format to display size_t values. The macro
487 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
488 ``printf`` function, whereas PyString_FromFormat has an independent
489 implementation and uses "%zd" on all platforms for size_t values.
490 This makes a difference on win64, where ``printf`` needs "%Id" to display
491 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000508 was correctly parsed but parsing of subsequent arguments failed.
509
Vinay Sajip35e3b032008-09-01 14:33:59 +0000510- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000511 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
512 mechanism. In the process, fix a bug where isinstance() and issubclass(),
513 when given a tuple of classes as second argument, were looking up
514 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
515 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000651What's New in Python 2.6 beta 3?
652================================
653
Barry Warsaw07a4a382008-08-21 01:15:08 +0000654*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000655
656Core and Builtins
657-----------------
658
Guido van Rossumf8402962008-08-20 15:01:50 +0000659- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
660 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
661 extensions do not automatically benefit from the class attribute
662 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
663 to their tp_flags field if they care. This is a backwards
664 compatibility feature; in 3.0, all types will use the cache by
665 default.
666
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000667- Keyword arguments can now follow starred arguments. (``f(a, *args,
668 keyword=23)`` is now valid syntax.)
669
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000670- ctypes function pointers that are COM methods have a boolean True
671 value again.
672
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000673- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
674 by denying s# to parse objects that have a releasebuffer procedure,
675 and introducing s*.
676
Georg Brandl1e13ea92008-08-11 09:07:59 +0000677- Issue #3537: Fix an assertion failure when an empty but presized dict
678 object was stored in the freelist.
679
Mark Dickinsonb6467572008-08-04 21:30:09 +0000680- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
681 ValueError consistently across platforms.
682
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000683- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
684 (64bit Unix, for example), unichr() would truncate its argument and return
685 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
686
Neal Norwitze7d8be82008-07-31 17:17:14 +0000687- Apply security patches from Apple.
688
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000689- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
690 PyErr_ExceptionMatches returns 0 when an exception occurs there.
691
Antoine Pitrou92f82162008-07-25 22:22:08 +0000692- Issue #1819: function calls with several named parameters are now on
693 average 35% faster (as measured by pybench).
694
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000695- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
696 the python debugger steps into a class statement: the free variables (local
697 variables defined in an outer scope) would be deleted from the outer scope.
698
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000699- Issue #2620: Overflow checking when allocating or reallocating memory
700 was not always being done properly in some python types and extension
701 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
702 all been updated to perform better checks and places in the code that
703 would previously leak memory on the error path when such an allocation
704 failed have been fixed.
705
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000706Library
707-------
708
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +0000709- Issue #3612: Added some missing basic types in ctypes.wintypes.
710
Benjamin Petersone977ad42008-08-20 01:42:01 +0000711- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
712 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
713
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000714- Issue #2234: distutils failed for some versions of the cygwin compiler. The
715 version reported by these tools does not necessarily follow the python
716 version numbering scheme, so the module is less strict when parsing it.
717
Nick Coghlanf70385a2008-08-18 12:42:46 +0000718- Issue #2235: Added Py3k warnings for types which will become unhashable
719 under the stricter __hash__ inheritance rules in 3.0. Several types
720 which did not meet the rules for hash invariants and were already
721 unhashable in 3.0 have now been explicitly flagged as unhashable in
722 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
723 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
724
Brett Cannon88f801d2008-08-18 00:46:22 +0000725- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
726 imported into the module but exposed as part of the module's API.
727
Brett Cannon7b96f072008-08-18 00:41:11 +0000728- Remove an unneeded import of abc.ABCMeta from 'inspect'.
729
Brett Cannon46225e72008-08-18 00:36:52 +0000730- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
731
Brett Cannon25c9d6a2008-08-17 22:10:11 +0000732- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
733
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000734- Issue #3575: Incremental decoder's decode function now takes bytearray
735 by using 's*' instead of 't#'.
736
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000737- Issue #2222: Fixed reference leak when occured os.rename()
738 fails unicode conversion on 2nd parameter. (windows only)
739
Facundo Batista94f243a2008-08-17 03:38:39 +0000740- Issue 2464. urllib2 now supports a malformation in the URL received
741 in a redirect.
742
Brett Cannonabe423e2008-08-16 21:47:07 +0000743- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000744 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000745
Facundo Batistaeb90b782008-08-16 14:44:07 +0000746- Issue #2776: fixed small issue when handling an URL with double slash
747 after a 302 response in the case of not going through a proxy.
748
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000749- Issue #2676: in the email package, content-type parsing was hanging on
750 pathological input because of quadratic or exponential behaviour of a
751 regular expression.
752
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000753- Issue #3476: binary buffered reading through the new "io" library is now
754 thread-safe.
755
Brett Cannonbf3157b2008-08-14 05:00:03 +0000756- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
757 since mimetools itself is deprecated. Because modules are cached, all
758 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
759
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000760- Issue #3134: shutil referenced undefined WindowsError symbol.
761
Robert Schuppenies14646332008-08-10 11:01:53 +0000762- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
763 menu entries were not deleted.
764
Brett Cannon83e81842008-08-09 23:30:55 +0000765- Copied the implementation of reduce() to _functools.reduce() to have a
766 version that did not raise a DeprecationWarning under -3.
767
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000768- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
769 a MemoryError rather than silently stop the iteration.
770
Guido van Rossum59ce9012008-08-09 14:55:34 +0000771- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
772 to _sre.compile() will now be rejected. This should not affect anybody
773 since the re.compile() function never generates invalid re-bytecode.
774
Skip Montanaroa032bf42008-08-08 22:52:51 +0000775- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
776 upon first access it can be automatically initialized from the csv file if
777 it wasn't initialized during instantiation.
778
Brett Cannon3aa2a492008-08-06 22:28:09 +0000779- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
780 the reload() built-in has been removed.
781
Brett Cannon7e30b672008-08-04 21:52:25 +0000782- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000783 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +0000784 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
785 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
786 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
787 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
788 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +0000789
Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000790- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
791 raised an AttributeError.
792
Benjamin Peterson01a24322008-07-28 23:35:27 +0000793- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000794 asking for a specific length. This problem only affected files opened
795 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000796
Mark Dickinsonfe84cce2008-07-27 06:39:07 +0000797- Issue #3449: Update decimal module to use most recent specification

815- Issue #3389: Allow resolving dotted names for handlers in logging
816 configuration files.
817
818- Deprecate the sunaudio module for removal in Python 3.0.
819
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000820- Issue #3394: zipfile.writestr sets external attributes when passed a
821 file name rather than a ZipInfo instance, so files are extracted with
822 mode 0600 rather than 000 under Unix.
823
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000824- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
825 argument in python 2.5, this broke code that subclassed Popen to include its
826 own poll method. Fixed my moving _deadstate to an _internal_poll method.

835
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000836- Issue #2235: the C API function PyObject_HashNotImplemented and its
837 interaction with the tp_hash slot (added in 2.6b2) are now documented
838
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000839- Issue #643841: The language reference now provides more detailed
840 coverage of the lookup process for special methods. The disclaimers
841 regarding lack of coverage of new-style classes have also been
842 removed, since the coverage is now fairly reasonable.

847
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000848*Release date: 17-Jul-2008*
849
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000850Core and Builtins
851-----------------
852
Georg Brandl3e483f62008-07-16 22:57:41 +0000853- Issue #3156: Fix inconsistent behavior of the bytearray type: all
854 its methods now allow for items objects that can be converted to
855 an integer using operator.index().
856
Mark Dickinson64b7e502008-07-16 09:40:03 +0000857- Issue #3360: Fix incorrect parsing of '020000000000.0', which
858 produced a ValueError instead of giving the correct float.
859
Eric Smitha5fa5a22008-07-16 00:11:49 +0000860- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
861 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
862
Mark Dickinson7103aa42008-07-15 19:08:33 +0000863- Issue #3008: the float type has a new instance method 'float.hex'
864 and a new class method 'float.fromhex' to convert floating-point
865 numbers to and from hexadecimal strings, respectively.
866
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000867- Issue #2235: __hash__ is once again inherited by default. To allow
868 collections.Hashable to remain meaningful in the presence of the
869 default hash implementation (object.__hash__), it is now possible
870 to explicit block inheritance of hash by setting __hash__=None at
871 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
872 level.
873
Nick Coghlanb028f502008-07-13 14:52:36 +0000874- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
875 the parent module cannot be found while performing an absolute import.
876 This means that an incorrectly defined __package__ attribute will
877 now only prevent relative imports in that module rather than causing
878 all imports from that module to fail.
879
Nick Coghlan14ff9942008-07-08 14:21:42 +0000880- Issue #2517: Allow unicode messages in Exceptions again by correctly
881 bypassing the instance dictionary when looking up __unicode__ on
882 new-style classes.
883
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000884- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
885 set to a custom object whose write() method happens to install
886 another file in sys.stdout.
887
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000888- Issue #3088: Corrected a race condition in classes derived from
889 threading.local: the first member set by a thread could be saved in
890 another thread's dictionary.
891
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000892- Issue #3004: Minor change to slice.indices(): the start and stop
893 arguments are now treated identically, making the behaviour easier
894 to describe and understand. For example, slice(None, -10,
895 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
896 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
897 10, -1).
898
Georg Brandl278fc502008-07-19 12:46:12 +0000899- Issue #3219: Calling a function with repeated keyword arguments,
900 f(a=2, a=23), would not cause a syntax error. This was a regression
901 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000902
Georg Brandl278fc502008-07-19 12:46:12 +0000903- Issue #2862: Make int and float freelist management consistent with
904 other freelists. Changes their CompactFreeList apis into
905 ClearFreeList apis and calls them via gc.collect().

911 api functions without holding the GIL, which could lead to a fatal
912 error when they failed.
913
Martin v. Löwisaabf4042008-08-02 07:20:25 +0000914- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1350 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001351 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001352
1353 This is controlled by the configure argument ``--with-universal-archs``:
1354
1355 - ``--with-universal-archs=all``: install 4-way universal
1356
1357 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1358
1359 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1360
1361 This option should be used in combination with ``--enable-universalsdk=``.
1362

1400 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00001401
Christian Heimese74c8f22008-04-19 02:23:57 +00001402- Added kill, terminate and send_signal(sig) to subprocess.Popen.
1403

1405 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00001406

Georg Brandl3ee81df2008-05-17 18:14:43 +00001413- Issue #1631171: Re-implement the 'warnings' module in C (the
1414 original Python code has been kept as backup). This will allow for
1415 using the 'warning's machinery in such places as the parser where
1416 use of pure Python code is not possible. Both the ``showarning()``
1417 and ``formatwarning()`` gain an optional 'line' argument which is
1418 not called by default for backwards-compatibility reasons. Setting
1419 ``warnings.showwarning()`` to an implementation that lacks support
1420 for the ``line`` argument will raise a DeprecationWarning.

1444
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001445- The getpass module has been improved on Unix. It now uses /dev/tty
1446 by default and uses stderr instead of stdout. A GetPassWarning is
1447 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00001448

Georg Brandl3ee81df2008-05-17 18:14:43 +00001462- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001463 extension modules between 32 and 64 bit platforms. See the distutls

1485 effort to facilitate running multiple instances of the entire
1486 regression test suite in parallel without issue.
1487 test_support.bind_port() has been fixed such that it will always
1488 return a unique port -- which wasn't always the case with the
1489 previous implementation, especially if socket options had been set
1490 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1491 new implementation of bind_port() will actually raise an exception
1492 if it is passed an AF_INET/SOCK_STREAM socket with either the
1493 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1494 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1495 the socket it's been passed. This currently only applies to
1496 Windows. This option prevents any other sockets from binding to the
1497 host/port we've bound to, thus removing the possibility of the
1498 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1499 when a second SOCK_STREAM socket binds and accepts to a host/port
1500 that's already been bound by another socket. The optional preferred
1501 port parameter to bind_port() has been removed. Under no
1502 circumstances should tests be hard coding ports!
1503
1504 test_support.find_unused_port() has also been introduced, which will
1505 pass a temporary socket object to bind_port() in order to obtain an
1506 unused port. The temporary socket object is then closed and
1507 deleted, and the port is returned. This method should only be used
1508 for obtaining an unused port in order to pass to an external program
1509 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1510 a parameter to a server-oriented class that doesn't give you direct
1511 access to the underlying socket used.
1512
1513 Finally, test_support.HOST has been introduced, which should be used
1514 for the host argument of any relevant socket calls (i.e. bind and
1515 connect).

1517 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001518 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001519 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1520 test_asynchat and test_socket_ssl.
1521
Georg Brandl3ee81df2008-05-17 18:14:43 +00001522 It is now possible for multiple instances of the regression test
1523 suite to run in parallel without issue.

1789Core and builtins
1790-----------------
1791
Fred Drakea8ee94b2008-03-01 02:45:07 +00001792- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001793 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001794
Georg Brandlad61bc82008-02-23 15:11:18 +00001795- Issue #2067: file.__exit__() now calls subclasses' close() method.
1796
1797- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001798
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001799- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001800 issue 215555 for a discussion.
1801
Eric Smitha73fbe72008-02-23 03:09:44 +00001802- Added the future_builtins module, which contains hex() and oct().
1803 These are the PEP 3127 version of these functions, designed to be
1804 compatible with the hex() and oct() builtins from Python 3.0. They
1805 differ slightly in their output formats from the existing, unchanged
1806 Python 2.6 builtins. The expected usage of the future_builtins
1807 module is:
1808 from future_builtins import hex, oct
1809
Eric Smith7ef40bf2008-02-20 23:34:22 +00001810- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1811 exponents for exponents with absolute value < 100. Follows C99
1812 standard. This is a change on Windows, which would use 3 digits.
1813 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1814 so that any alterations it does to the resulting string will be
1815 available in stringlib/formatter.h (for float.__format__).
1816
Eric Smith5a3c1352008-02-19 13:21:56 +00001817- Implemented PEP 3101, Advanced String Formatting. This adds a new
1818 builtin format(); a format() method for str and unicode; a
1819 __format__() method to object, str, unicode, int, long, float, and
1820 datetime; the class string.Formatter; and the C API
1821 PyObject_Format().
1822
Georg Brandl3ee81df2008-05-17 18:14:43 +00001823- Fixed several potential crashes, all caused by specially crafted
1824 __del__ methods exploiting objects in temporarily inconsistent
1825 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001826
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001827- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001828 prevent a possible crash: an Abstract Base Class would try to access
1829 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001830
Georg Brandl3ee81df2008-05-17 18:14:43 +00001831- Fixed repr() and str() of complex numbers with infinity or nan as
1832 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001833
Georg Brandl3ee81df2008-05-17 18:14:43 +00001834- Clear all free lists during a gc.collect() of the highest generation
1835 in order to allow pymalloc to free more arenas. Python may give back
1836 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001837
Georg Brandl3ee81df2008-05-17 18:14:43 +00001838- Issue #2045: Fix an infinite recursion triggered when printing a
1839 subclass of collections.defaultdict, if its default_factory is set
1840 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001841
Christian Heimesf75dbef2008-02-08 00:11:31 +00001842- Fixed a minor memory leak in dictobject.c. The content of the free
1843 list was not freed on interpreter shutdown.
1844
Georg Brandl3ee81df2008-05-17 18:14:43 +00001845- Limit free list of method and builtin function objects to 256
1846 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001847
Georg Brandl3ee81df2008-05-17 18:14:43 +00001848- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1849 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001850 to compact the internal free lists of pre-allocted ints and floats.
1851
Georg Brandl3ee81df2008-05-17 18:14:43 +00001852- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1853 calls. Python expected the return type int but the fork familie
1854 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001855
Georg Brandl3ee81df2008-05-17 18:14:43 +00001856- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1857 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001858
Georg Brandl3ee81df2008-05-17 18:14:43 +00001859- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1860 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001861
Georg Brandl3ee81df2008-05-17 18:14:43 +00001862- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
1863 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00001864
Georg Brandl3ee81df2008-05-17 18:14:43 +00001865- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1866 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001867
Georg Brandl3ee81df2008-05-17 18:14:43 +00001868- Patch #1473257: generator objects gain a gi_code attribute. This is
1869 the same object as the func_code attribute of the function that
1870 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001871
Georg Brandl3ee81df2008-05-17 18:14:43 +00001872- Issue #1920: "while 0" statements were completely removed by the
1873 compiler, even in the presence of an "else" clause, which is
1874 supposed to be run when the condition is false. Now the compiler
1875 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001876
Guido van Rossumeead05f2008-01-24 18:21:02 +00001877- A few crashers fixed: weakref_in_del.py (issue #1377858);
1878 loosing_dict_ref.py (issue #1303614, test67.py);
1879 borrowed_ref_[34].py (not in tracker).
1880
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001881- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001882 suppressed while an extension is loaded by calling SetErrorMode in
1883 dynload_win.c. The error is still reported properly.
1884
Georg Brandl3ee81df2008-05-17 18:14:43 +00001885- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001886 several extension methods and modules do not work without unicode
1887 support.
1888
Georg Brandl26543b12008-01-21 18:36:51 +00001889- Issue #1882: when compiling code from a string, encoding cookies in the
1890 second line of code were not always recognized correctly.
1891
Georg Brandl14404b62008-01-19 19:27:05 +00001892- Issue #1679: "0x" was taken as a valid integer literal.
1893
Georg Brandl6caad7d2008-01-26 14:19:22 +00001894- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001895 added.
1896
Christian Heimesc94e2b52008-01-14 04:13:37 +00001897- sys.float_info / PyFloat_GetInfo: The floating point information
1898 object was converted from a dict to a specialized structseq object.
1899
Georg Brandl3ee81df2008-05-17 18:14:43 +00001900- Patch #1816: Added sys.flags structseq. It exposes the status of
1901 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001902
Georg Brandl3ee81df2008-05-17 18:14:43 +00001903- Objects/structseq.c: Implemented new structseq representation. The
1904 patch makes structseqs (e.g. the return value of os.stat) more
1905 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001906
Georg Brandl3ee81df2008-05-17 18:14:43 +00001907- Patch #1700288: added a type attribute cache that caches method
1908 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00001909
Neal Norwitz3fc15b82008-01-10 05:42:58 +00001910- Bug #1776: __import__() no longer accepts filenames on any platform.
1911 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00001912
Georg Brandlaed6c662008-01-07 17:25:53 +00001913- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
1914
Georg Brandl3ee81df2008-05-17 18:14:43 +00001915- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
1916 envvar and sys.dont_write_bytecode attribute. All these can be set
1917 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00001918
Georg Brandl3ee81df2008-05-17 18:14:43 +00001919- Improve some exception messages when Windows fails to load an
1920 extension module. Now we get for example '%1 is not a valid Win32
1921 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00001922
Georg Brandl3ee81df2008-05-17 18:14:43 +00001923- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001925- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
1926 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00001927
Christian Heimes0a8143f2007-12-18 23:22:54 +00001928- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00001929 and INF. float("nan"), float("inf") and float("-inf") now work on
1930 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001931
Georg Brandl3ee81df2008-05-17 18:14:43 +00001932- Compiler now generates simpler and faster code for dictionary
1933 literals. The oparg for BUILD_MAP now indicates an estimated
1934 dictionary size. There is a new opcode, STORE_MAP, for adding
1935 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001969- Issue #1265: Fix a problem with sys.settrace, if the tracing
1970 function uses a generator expression when at the same time the
1971 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00001972
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00001973- sets and frozensets now have an isdisjoint() method.
1974
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00001975- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00001977- Fix warnings found by the new version of the Coverity checker.
1978
Georg Brandl3ee81df2008-05-17 18:14:43 +00001979- The enumerate() builtin function is no longer bounded to sequences
1980 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
1981 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00001982
Georg Brandl3ee81df2008-05-17 18:14:43 +00001983- Issue #1686386: Tuple's tp_repr did not take into account the
1984 possibility of having a self-referential tuple, which is possible
1985 from C code. Nor did object's tp_str consider that a type's tp_str
1986 could do something that could lead to an inifinite recursion.
1987 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
1988 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00001989
Georg Brandl3ee81df2008-05-17 18:14:43 +00001990- Issue #1164: It was possible to trigger deadlock when using the
1991 'print' statement to write to a file since the GIL was not released
1992 as needed. Now PyObject_Print() does the right thing along with
1993 various tp_print implementations of the built-in types and those in

Georg Brandl3ee81df2008-05-17 18:14:43 +00001996- Issue #1147: Exceptions were directly allowing string exceptions in
1997 their throw() method even though string exceptions no longer
1998 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00001999
Georg Brandl3ee81df2008-05-17 18:14:43 +00002000- Issue #1096: Prevent a segfault from getting the repr of a very
2001 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002002
Brett Cannon1e534b52007-09-07 04:18:30 +00002003- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002004 PyObject_Call() never calling back out to Python code to trigger
2005 recursion depth updates/checks. Required the creation of a static
2006 RuntimeError instance in case normalizing an exception put the
2007 recursion check value past its limit. Fixes crashers
2008 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002023- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002024 __*__ attributes. (Some already existed, e.g., __doc__ and
2025 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002026
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002027- Add -3 option to the interpreter to warn about features that are

2031 calls.
2032
Collin Winter62903052007-05-18 23:11:24 +00002033- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002034 "except E as target:". This is to provide forwards compatibility
2035 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002036
Brett Cannon229cee22007-05-05 01:34:02 +00002037- Deprecate BaseException.message as per PEP 352.
2038
Georg Brandl3ee81df2008-05-17 18:14:43 +00002039- Issue #1303614: don't expose object's __dict__ when the dict is

2041
Vinay Sajip8549ce32007-05-06 17:53:37 +00002042- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002043 setting a plain string, ie don't expand to single letter identifiers.
2044
Raymond Hettinger13936692007-04-11 18:40:58 +00002045- Request #1191699: Slices can now be pickled.
2046
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002047- Request #1193128: str.translate() now allows a None argument for
2048 translations that only remove characters without re-mapping the
2049 remaining characters.
2050
Georg Brandl5cb76c12007-03-21 09:00:39 +00002051- Patch #1682205: a TypeError while unpacking an iterable is no longer

2053
Neal Norwitzaa754b72007-03-21 06:39:48 +00002054- Remove unused file Python/fmod.c.
2055
Guido van Rossum143b5642007-03-23 04:58:42 +00002056- Bug #1683368: The object.__init__() and object.__new__() methods are
2057 now stricter in rejecting excess arguments. The only time when
2058 either allows excess arguments is when it is not overridden and the
2059 other one is. For backwards compatibility, when both are
2060 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002061 warning later). Also, type.__init__() insists on the same signature
2062 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002063
Georg Brandl3ee81df2008-05-17 18:14:43 +00002064- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2065 object to complex using its __complex__() method before falling back
2066 to the __float__() method. Therefore, the functions in the cmath
2067 module now can operate on objects that define a __complex__()
2068 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002069

2085
Georg Brandl7b9c5552007-03-12 14:30:05 +00002086- Bug #1678647: write a newline after printing an exception in any
2087 case, even when converting the value to a string failed.
2088
Georg Brandl871f1bc2007-03-12 13:17:36 +00002089- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002090 its argument, if it exists. If not, it will work like before. This
2091 allows customizing the output of dir() in the presence of a
2092 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002093
Collin Winter276887b2007-03-12 16:11:39 +00002094- Patch #922167: Python no longer segfaults when faced with infinitely
2095 self-recursive reload() calls (as reported by bug #742342).

2101 parthensized forms. This means complex(repr(x)) now works instead of
2102 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002103
Georg Brandlaa2321b2007-03-07 00:40:28 +00002104- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002105 makes the filenames the warning module prints much more sensible
2106 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002107

Georg Brandl0fca97a2007-03-05 22:28:08 +00002119- Patch #1674228: when assigning a slice (old-style), check for the
2120 sq_ass_slice instead of the sq_slice slot.
2121
Georg Brandl3ee81df2008-05-17 18:14:43 +00002122- When printing an unraisable error, don't print exceptions. before
2123 the name. This duplicates the behavior whening normally printing
2124 exceptions.

2133 created a weakref on itself during a __del__ call for new-style
2134 classes (classic classes still have the bug).

2733 Python would crash instead of raising an error.
2734
Thomas Hellerc2f77252007-03-09 19:21:28 +00002735- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
2736 returned string up to the first NUL character.

2750 accepted in TestSuite.addTest(). This should cause no
2751 incompatibility since it never made sense with ordinary subclasses
2752 -- the failure just occurred later, with a more cumbersome
2753 exception.

3037 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003038
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003040 that the SMTP.starttls() caller no longer needs to call ehlo()
3041 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003042 does not claim to support starttls. Adds the
3043 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3124 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3125 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003142 time so that opening a database previously created with the DB_DUP
3143 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3144 opens. Specifically: dictionary assignment to a DB object will
3145 replace all values for a given key when the database allows
3146 duplicate values. DB users should use DB.put(k, v) when they want
3147 to store duplicates; not DB[k] = v.

3154 characters with ASCII value less than 32. Also, it correctly quotes
3155 dots only if they occur on a single line, as opposed to the previous
3156 behavior of quoting dots if they are the second character of any
3157 line.

Neal Norwitz92422fb2006-08-18 03:57:54 +00003479C API
3480-----
3481
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Unified naming convention for free lists and their limits. All free
3483 lists in Object/ are named ``free_list``, the counter ``numfree``
3484 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3485 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003486
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3488 to ``PyTuple_SetItem``, it can be used to populate a brand new
3489 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003490
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003491- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003493- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3494 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3495 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003496
3497- Patch #1720595: add T_BOOL to the range of structmember types.
3498
3499- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3500 ``PyFloat_GetInfo()`` to the float API.
3501
Georg Brandl3ee81df2008-05-17 18:14:43 +00003502- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3503 of w# format code incorrectly truncated the length to an int, even
3504 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3505 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003506
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3508 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- PEP 3123: Provide forward compatibility with Python 3.0, while
3511 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3512 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003513
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3515 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003516
3517- Patch #1733960: Allow T_LONGLONG to accept ints.
3518
3519- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3520

3524
3525- Fix some leftovers from the conversion from int to Py_ssize_t
3526 (relevant to strings and sequences of more than 2**31 items).
3527
3528- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3529 outside of pystate.c and should not be necessary.
3530
Georg Brandl3ee81df2008-05-17 18:14:43 +00003531- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3532 absolute imports. In earlier versions they might have used relative
3533 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003534
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3536 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003537
Georg Brandl3ee81df2008-05-17 18:14:43 +00003538- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3539 macro so it can be used as an expression.

3544
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3546 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3547 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3548 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003549
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00003561- buildtools now raises a DeprecationWarning.
3562
Georg Brandl3ee81df2008-05-17 18:14:43 +00003563- Removed the macfs module. It had been deprecated since Python 2.5.
3564 This lead to the deprecation of macostools.touched() as it relied
3565 solely on macfs and was a no-op under OS X.
