32 an existing .py counterpart, override the co_filename attributes of all
33 code objects if the original filename is obsolete (which can happen if the
34 file has been renamed, moved, or if it is accessed through different paths).
35 Patch by Ziga Seilnacht and Jean-Paul Calderone.
36
Georg Brandl734373c2009-01-03 21:55:17 +000037- Issue #4075: Use OutputDebugStringW in Py_FatalError.

63 exceptions.
64

Vinay Sajip6badbe92009-01-20 22:49:13 +000072- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +000073 method on file objects with closefd=False. The file descriptor is still

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

140 traditional 2.x file object.

Amaury Forgeot d'Arc0293c802009-01-17 16:46:35 +0000142- Issue #3997: zipfiles generated with more than 65536 files could not be

171 zipimport (or any other conformant PEP 302 loader). Original patch by
172 Alexander Belopolsky.
173
174- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
175 302 conformant loader) will now work correctly in most cases (they
176 are still subject to the constraints that exist for all code running
177 from inside a module loaded via a PEP 302 loader and attempting to
178 perform IO operations based on __file__). Original patch by
179 Alexander Belopolsky.

215
Benjamin Peterson866eba92008-11-19 22:05:53 +0000216- Issue #4348: Some bytearray methods returned that didn't cause any change to
217 the bytearray, returned the same bytearray instead of a copy.
218
Amaury Forgeot d'Arc83be3d22008-11-18 22:27:00 +0000219- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

235 returned a path longer than MAX_PATH. (But It's doubtful this code path is

237
Amaury Forgeot d'Arc00c94ed2008-10-07 20:40:09 +0000238- Issue #4069: When set.remove(element) is used with a set element, the element
239 is temporarily replaced with an equivalent frozenset. But the eventual

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000501- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
502
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000503- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
504 PyString_FromFormat or PyErr_Format to display size_t values. The macro
505 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
506 ``printf`` function, whereas PyString_FromFormat has an independent
507 implementation and uses "%zd" on all platforms for size_t values.
508 This makes a difference on win64, where ``printf`` needs "%Id" to display
509 64bit values.

527
Vinay Sajip35e3b032008-09-01 14:33:59 +0000528- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000529 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
530 mechanism. In the process, fix a bug where isinstance() and issubclass(),

532 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
533 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000669What's New in Python 2.6 beta 3?
670================================
671
Barry Warsaw07a4a382008-08-21 01:15:08 +0000672*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000673
674Core and Builtins
675-----------------
676
Guido van Rossumf8402962008-08-20 15:01:50 +0000677- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
678 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
679 extensions do not automatically benefit from the class attribute
680 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
681 to their tp_flags field if they care. This is a backwards
682 compatibility feature; in 3.0, all types will use the cache by
683 default.
684
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000685- Keyword arguments can now follow starred arguments. (``f(a, *args,
686 keyword=23)`` is now valid syntax.)
687
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000688- ctypes function pointers that are COM methods have a boolean True
689 value again.
690
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000691- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
692 by denying s# to parse objects that have a releasebuffer procedure,
693 and introducing s*.
694
Georg Brandl1e13ea92008-08-11 09:07:59 +0000695- Issue #3537: Fix an assertion failure when an empty but presized dict
696 object was stored in the freelist.
697
Mark Dickinsonb6467572008-08-04 21:30:09 +0000698- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
699 ValueError consistently across platforms.
700
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000701- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
702 (64bit Unix, for example), unichr() would truncate its argument and return
703 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
704
Neal Norwitze7d8be82008-07-31 17:17:14 +0000705- Apply security patches from Apple.
706
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000707- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
708 PyErr_ExceptionMatches returns 0 when an exception occurs there.
709
Antoine Pitrou92f82162008-07-25 22:22:08 +0000710- Issue #1819: function calls with several named parameters are now on
711 average 35% faster (as measured by pybench).
712
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000713- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
714 the python debugger steps into a class statement: the free variables (local
715 variables defined in an outer scope) would be deleted from the outer scope.
716
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000717- Issue #2620: Overflow checking when allocating or reallocating memory
718 was not always being done properly in some python types and extension
719 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
720 all been updated to perform better checks and places in the code that
721 would previously leak memory on the error path when such an allocation
722 failed have been fixed.
723
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000724Library
725-------
726
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +0000727- Issue #3612: Added some missing basic types in ctypes.wintypes.
728
Benjamin Petersone977ad42008-08-20 01:42:01 +0000729- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
730 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
731
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000732- Issue #2234: distutils failed for some versions of the cygwin compiler. The
733 version reported by these tools does not necessarily follow the python
734 version numbering scheme, so the module is less strict when parsing it.
735
Nick Coghlanf70385a2008-08-18 12:42:46 +0000736- Issue #2235: Added Py3k warnings for types which will become unhashable
737 under the stricter __hash__ inheritance rules in 3.0. Several types
738 which did not meet the rules for hash invariants and were already
739 unhashable in 3.0 have now been explicitly flagged as unhashable in
740 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
741 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
742
Brett Cannon88f801d2008-08-18 00:46:22 +0000743- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
744 imported into the module but exposed as part of the module's API.
745
Brett Cannon7b96f072008-08-18 00:41:11 +0000746- Remove an unneeded import of abc.ABCMeta from 'inspect'.

749
Brett Cannon25c9d6a2008-08-17 22:10:11 +0000750- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
751
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000752- Issue #3575: Incremental decoder's decode function now takes bytearray
753 by using 's*' instead of 't#'.
754
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000755- Issue #2222: Fixed reference leak when occured os.rename()
756 fails unicode conversion on 2nd parameter. (windows only)
757
Facundo Batista94f243a2008-08-17 03:38:39 +0000758- Issue 2464. urllib2 now supports a malformation in the URL received
759 in a redirect.
760
Brett Cannonabe423e2008-08-16 21:47:07 +0000761- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000762 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000763
Facundo Batistaeb90b782008-08-16 14:44:07 +0000764- Issue #2776: fixed small issue when handling an URL with double slash
765 after a 302 response in the case of not going through a proxy.
766
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000767- Issue #2676: in the email package, content-type parsing was hanging on
768 pathological input because of quadratic or exponential behaviour of a
769 regular expression.
770
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000771- Issue #3476: binary buffered reading through the new "io" library is now
772 thread-safe.
773
Brett Cannonbf3157b2008-08-14 05:00:03 +0000774- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
775 since mimetools itself is deprecated. Because modules are cached, all
776 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
777
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000778- Issue #3134: shutil referenced undefined WindowsError symbol.
779
Robert Schuppenies14646332008-08-10 11:01:53 +0000780- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
781 menu entries were not deleted.
782
Brett Cannon83e81842008-08-09 23:30:55 +0000783- Copied the implementation of reduce() to _functools.reduce() to have a
784 version that did not raise a DeprecationWarning under -3.
785
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000786- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
787 a MemoryError rather than silently stop the iteration.
788
Guido van Rossum59ce9012008-08-09 14:55:34 +0000789- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
790 to _sre.compile() will now be rejected. This should not affect anybody
791 since the re.compile() function never generates invalid re-bytecode.
792
Skip Montanaroa032bf42008-08-08 22:52:51 +0000793- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
794 upon first access it can be automatically initialized from the csv file if
795 it wasn't initialized during instantiation.
796
Brett Cannon3aa2a492008-08-06 22:28:09 +0000797- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
798 the reload() built-in has been removed.
799
Brett Cannon7e30b672008-08-04 21:52:25 +0000800- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000801 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

805 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
806 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +0000807
Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000808- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
809 raised an AttributeError.
810
Benjamin Peterson01a24322008-07-28 23:35:27 +0000811- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000812 asking for a specific length. This problem only affected files opened
813 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000814

836- Deprecate the sunaudio module for removal in Python 3.0.
837
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000838- Issue #3394: zipfile.writestr sets external attributes when passed a
839 file name rather than a ZipInfo instance, so files are extracted with
840 mode 0600 rather than 000 under Unix.
841
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000842- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
843 argument in python 2.5, this broke code that subclassed Popen to include its
844 own poll method. Fixed my moving _deadstate to an _internal_poll method.

852-------------
853
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000854- Issue #2235: the C API function PyObject_HashNotImplemented and its
855 interaction with the tp_hash slot (added in 2.6b2) are now documented
856

858 coverage of the lookup process for special methods. The disclaimers
859 regarding lack of coverage of new-style classes have also been
860 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000863What's New in Python 2.6 beta 2?
864================================
865
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000866*Release date: 17-Jul-2008*
867
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000868Core and Builtins
869-----------------
870
Georg Brandl3e483f62008-07-16 22:57:41 +0000871- Issue #3156: Fix inconsistent behavior of the bytearray type: all
872 its methods now allow for items objects that can be converted to
873 an integer using operator.index().
874
Mark Dickinson64b7e502008-07-16 09:40:03 +0000875- Issue #3360: Fix incorrect parsing of '020000000000.0', which
876 produced a ValueError instead of giving the correct float.
877
Eric Smitha5fa5a22008-07-16 00:11:49 +0000878- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
879 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
880
Mark Dickinson7103aa42008-07-15 19:08:33 +0000881- Issue #3008: the float type has a new instance method 'float.hex'
882 and a new class method 'float.fromhex' to convert floating-point
883 numbers to and from hexadecimal strings, respectively.
884
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000885- Issue #2235: __hash__ is once again inherited by default. To allow
886 collections.Hashable to remain meaningful in the presence of the
887 default hash implementation (object.__hash__), it is now possible
888 to explicit block inheritance of hash by setting __hash__=None at
889 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
890 level.
891
Nick Coghlanb028f502008-07-13 14:52:36 +0000892- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
893 the parent module cannot be found while performing an absolute import.
894 This means that an incorrectly defined __package__ attribute will
895 now only prevent relative imports in that module rather than causing
896 all imports from that module to fail.
897
Nick Coghlan14ff9942008-07-08 14:21:42 +0000898- Issue #2517: Allow unicode messages in Exceptions again by correctly
899 bypassing the instance dictionary when looking up __unicode__ on
900 new-style classes.
901
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000902- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
903 set to a custom object whose write() method happens to install
904 another file in sys.stdout.
905
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000906- Issue #3088: Corrected a race condition in classes derived from
907 threading.local: the first member set by a thread could be saved in
908 another thread's dictionary.
909
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000910- Issue #3004: Minor change to slice.indices(): the start and stop
911 arguments are now treated identically, making the behaviour easier
912 to describe and understand. For example, slice(None, -10,
913 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
914 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
915 10, -1).
916
Georg Brandl278fc502008-07-19 12:46:12 +0000917- Issue #3219: Calling a function with repeated keyword arguments,
918 f(a=2, a=23), would not cause a syntax error. This was a regression
919 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000920
Georg Brandl278fc502008-07-19 12:46:12 +0000921- Issue #2862: Make int and float freelist management consistent with
922 other freelists. Changes their CompactFreeList apis into
923 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +0000928- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
929 api functions without holding the GIL, which could lead to a fatal
930 error when they failed.
931
Martin v. Löwisaabf4042008-08-02 07:20:25 +0000932- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Georg Brandl5cc774e2008-06-11 20:28:06 +00001369 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001370
1371 This is controlled by the configure argument ``--with-universal-archs``:
1372
1373 - ``--with-universal-archs=all``: install 4-way universal
1374
1375 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1376
1377 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1378

1418 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001431- Issue #1631171: Re-implement the 'warnings' module in C (the
1432 original Python code has been kept as backup). This will allow for
1433 using the 'warning's machinery in such places as the parser where
1434 use of pure Python code is not possible. Both the ``showarning()``
1435 and ``formatwarning()`` gain an optional 'line' argument which is
1436 not called by default for backwards-compatibility reasons. Setting
1437 ``warnings.showwarning()`` to an implementation that lacks support
1438 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001463- The getpass module has been improved on Unix. It now uses /dev/tty
1464 by default and uses stderr instead of stdout. A GetPassWarning is
1465 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001493- Issue #2385: distutils.core.run_script() makes __file__ available,
1494 so the controlled environment will more closely mirror the typical
1495 script environment. This supports setup.py scripts that refer to
1496 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001501- Issue #2550: The approach used by client/server code for obtaining
1502 ports to listen on in network-oriented tests has been refined in an
1503 effort to facilitate running multiple instances of the entire
1504 regression test suite in parallel without issue.
1505 test_support.bind_port() has been fixed such that it will always
1506 return a unique port -- which wasn't always the case with the
1507 previous implementation, especially if socket options had been set
1508 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1509 new implementation of bind_port() will actually raise an exception
1510 if it is passed an AF_INET/SOCK_STREAM socket with either the
1511 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1512 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1513 the socket it's been passed. This currently only applies to
1514 Windows. This option prevents any other sockets from binding to the
1515 host/port we've bound to, thus removing the possibility of the
1516 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1517 when a second SOCK_STREAM socket binds and accepts to a host/port
1518 that's already been bound by another socket. The optional preferred
1519 port parameter to bind_port() has been removed. Under no
1520 circumstances should tests be hard coding ports!
1521
1522 test_support.find_unused_port() has also been introduced, which will
1523 pass a temporary socket object to bind_port() in order to obtain an
1524 unused port. The temporary socket object is then closed and
1525 deleted, and the port is returned. This method should only be used
1526 for obtaining an unused port in order to pass to an external program
1527 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1528 a parameter to a server-oriented class that doesn't give you direct
1529 access to the underlying socket used.
1530
1531 Finally, test_support.HOST has been introduced, which should be used
1532 for the host argument of any relevant socket calls (i.e. bind and
1533 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001534
1535 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001536 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001537 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1538 test_asynchat and test_socket_ssl.
1539
Georg Brandl3ee81df2008-05-17 18:14:43 +00001540 It is now possible for multiple instances of the regression test
1541 suite to run in parallel without issue.

1807Core and builtins
1808-----------------
1809
Fred Drakea8ee94b2008-03-01 02:45:07 +00001810- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001811 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001812
Georg Brandlad61bc82008-02-23 15:11:18 +00001813- Issue #2067: file.__exit__() now calls subclasses' close() method.
1814
1815- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001816
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001817- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001818 issue 215555 for a discussion.
1819
Eric Smitha73fbe72008-02-23 03:09:44 +00001820- Added the future_builtins module, which contains hex() and oct().
1821 These are the PEP 3127 version of these functions, designed to be
1822 compatible with the hex() and oct() builtins from Python 3.0. They
1823 differ slightly in their output formats from the existing, unchanged
1824 Python 2.6 builtins. The expected usage of the future_builtins
1825 module is:
1826 from future_builtins import hex, oct
1827
Eric Smith7ef40bf2008-02-20 23:34:22 +00001828- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1829 exponents for exponents with absolute value < 100. Follows C99
1830 standard. This is a change on Windows, which would use 3 digits.
1831 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1832 so that any alterations it does to the resulting string will be
1833 available in stringlib/formatter.h (for float.__format__).
1834
Eric Smith5a3c1352008-02-19 13:21:56 +00001835- Implemented PEP 3101, Advanced String Formatting. This adds a new
1836 builtin format(); a format() method for str and unicode; a
1837 __format__() method to object, str, unicode, int, long, float, and
1838 datetime; the class string.Formatter; and the C API
1839 PyObject_Format().
1840
Georg Brandl3ee81df2008-05-17 18:14:43 +00001841- Fixed several potential crashes, all caused by specially crafted
1842 __del__ methods exploiting objects in temporarily inconsistent
1843 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001844
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001845- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001846 prevent a possible crash: an Abstract Base Class would try to access
1847 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001848
Georg Brandl3ee81df2008-05-17 18:14:43 +00001849- Fixed repr() and str() of complex numbers with infinity or nan as
1850 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001851
Georg Brandl3ee81df2008-05-17 18:14:43 +00001852- Clear all free lists during a gc.collect() of the highest generation
1853 in order to allow pymalloc to free more arenas. Python may give back
1854 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001855
Georg Brandl3ee81df2008-05-17 18:14:43 +00001856- Issue #2045: Fix an infinite recursion triggered when printing a
1857 subclass of collections.defaultdict, if its default_factory is set
1858 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001859
Christian Heimesf75dbef2008-02-08 00:11:31 +00001860- Fixed a minor memory leak in dictobject.c. The content of the free
1861 list was not freed on interpreter shutdown.
1862
Georg Brandl3ee81df2008-05-17 18:14:43 +00001863- Limit free list of method and builtin function objects to 256
1864 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001865
Georg Brandl3ee81df2008-05-17 18:14:43 +00001866- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1867 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001868 to compact the internal free lists of pre-allocted ints and floats.
1869
Georg Brandl3ee81df2008-05-17 18:14:43 +00001870- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1871 calls. Python expected the return type int but the fork familie
1872 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001873
Georg Brandl3ee81df2008-05-17 18:14:43 +00001874- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1875 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001876

1884 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001885
Georg Brandl3ee81df2008-05-17 18:14:43 +00001886- Patch #1473257: generator objects gain a gi_code attribute. This is
1887 the same object as the func_code attribute of the function that
1888 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001889
Georg Brandl3ee81df2008-05-17 18:14:43 +00001890- Issue #1920: "while 0" statements were completely removed by the
1891 compiler, even in the presence of an "else" clause, which is
1892 supposed to be run when the condition is false. Now the compiler
1893 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001894
Guido van Rossumeead05f2008-01-24 18:21:02 +00001895- A few crashers fixed: weakref_in_del.py (issue #1377858);
1896 loosing_dict_ref.py (issue #1303614, test67.py);
1897 borrowed_ref_[34].py (not in tracker).
1898
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001899- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001900 suppressed while an extension is loaded by calling SetErrorMode in
1901 dynload_win.c. The error is still reported properly.
1902
Georg Brandl3ee81df2008-05-17 18:14:43 +00001903- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001904 several extension methods and modules do not work without unicode
1905 support.
1906
Georg Brandl26543b12008-01-21 18:36:51 +00001907- Issue #1882: when compiling code from a string, encoding cookies in the
1908 second line of code were not always recognized correctly.
1909
Georg Brandl14404b62008-01-19 19:27:05 +00001910- Issue #1679: "0x" was taken as a valid integer literal.
1911
Georg Brandl6caad7d2008-01-26 14:19:22 +00001912- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001913 added.
1914
Christian Heimesc94e2b52008-01-14 04:13:37 +00001915- sys.float_info / PyFloat_GetInfo: The floating point information
1916 object was converted from a dict to a specialized structseq object.
1917
Georg Brandl3ee81df2008-05-17 18:14:43 +00001918- Patch #1816: Added sys.flags structseq. It exposes the status of
1919 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001920
Georg Brandl3ee81df2008-05-17 18:14:43 +00001921- Objects/structseq.c: Implemented new structseq representation. The
1922 patch makes structseqs (e.g. the return value of os.stat) more
1923 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001924
Georg Brandl3ee81df2008-05-17 18:14:43 +00001925- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00001947 and INF. float("nan"), float("inf") and float("-inf") now work on
1948 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001949
Georg Brandl3ee81df2008-05-17 18:14:43 +00001950- Compiler now generates simpler and faster code for dictionary
1951 literals. The oparg for BUILD_MAP now indicates an estimated
1952 dictionary size. There is a new opcode, STORE_MAP, for adding
1953 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001997- The enumerate() builtin function is no longer bounded to sequences
1998 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
1999 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002000
Georg Brandl3ee81df2008-05-17 18:14:43 +00002001- Issue #1686386: Tuple's tp_repr did not take into account the
2002 possibility of having a self-referential tuple, which is possible
2003 from C code. Nor did object's tp_str consider that a type's tp_str
2004 could do something that could lead to an inifinite recursion.
2005 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2006 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002007
Georg Brandl3ee81df2008-05-17 18:14:43 +00002008- Issue #1164: It was possible to trigger deadlock when using the
2009 'print' statement to write to a file since the GIL was not released
2010 as needed. Now PyObject_Print() does the right thing along with
2011 various tp_print implementations of the built-in types and those in
2012 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002013
Georg Brandl3ee81df2008-05-17 18:14:43 +00002014- Issue #1147: Exceptions were directly allowing string exceptions in
2015 their throw() method even though string exceptions no longer
2016 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002017
Georg Brandl3ee81df2008-05-17 18:14:43 +00002018- Issue #1096: Prevent a segfault from getting the repr of a very
2019 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002020
Brett Cannon1e534b52007-09-07 04:18:30 +00002021- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002022 PyObject_Call() never calling back out to Python code to trigger
2023 recursion depth updates/checks. Required the creation of a static
2024 RuntimeError instance in case normalizing an exception put the
2025 recursion check value past its limit. Fixes crashers
2026 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002027

Neal Norwitz0ac60192007-05-27 04:08:54 +00002041- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002042 __*__ attributes. (Some already existed, e.g., __doc__ and
2043 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002044
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002045- Add -3 option to the interpreter to warn about features that are
2046 deprecated and will be changed/removed in Python 3.0.
2047
Georg Brandl2134e752007-05-21 20:34:16 +00002048- Patch #1686487: you can now pass any mapping after '**' in function
2049 calls.
2050
Collin Winter62903052007-05-18 23:11:24 +00002051- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002052 "except E as target:". This is to provide forwards compatibility
2053 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002054
Brett Cannon229cee22007-05-05 01:34:02 +00002055- Deprecate BaseException.message as per PEP 352.
2056
Georg Brandl3ee81df2008-05-17 18:14:43 +00002057- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002058 inherited from a builtin base.
2059
Vinay Sajip8549ce32007-05-06 17:53:37 +00002060- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002061 setting a plain string, ie don't expand to single letter identifiers.
2062
Raymond Hettinger13936692007-04-11 18:40:58 +00002063- Request #1191699: Slices can now be pickled.
2064
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002065- Request #1193128: str.translate() now allows a None argument for
2066 translations that only remove characters without re-mapping the
2067 remaining characters.
2068
Georg Brandl5cb76c12007-03-21 09:00:39 +00002069- Patch #1682205: a TypeError while unpacking an iterable is no longer

2071
Neal Norwitzaa754b72007-03-21 06:39:48 +00002072- Remove unused file Python/fmod.c.
2073
Guido van Rossum143b5642007-03-23 04:58:42 +00002074- Bug #1683368: The object.__init__() and object.__new__() methods are
2075 now stricter in rejecting excess arguments. The only time when
2076 either allows excess arguments is when it is not overridden and the
2077 other one is. For backwards compatibility, when both are
2078 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002079 warning later). Also, type.__init__() insists on the same signature
2080 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002081
Georg Brandl3ee81df2008-05-17 18:14:43 +00002082- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2083 object to complex using its __complex__() method before falling back
2084 to the __float__() method. Therefore, the functions in the cmath
2085 module now can operate on objects that define a __complex__()
2086 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002087
Georg Brandl3ee81df2008-05-17 18:14:43 +00002088- Patch #1623563: allow __class__ assignment for classes with
2089 __slots__. The old and the new class are still required to have the
2090 same slot names.

2097 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002098
Georg Brandl3ee81df2008-05-17 18:14:43 +00002099- Patch #1680015: Don't modify __slots__ tuple if it contains an

2103
Georg Brandl7b9c5552007-03-12 14:30:05 +00002104- Bug #1678647: write a newline after printing an exception in any
2105 case, even when converting the value to a string failed.
2106
Georg Brandl871f1bc2007-03-12 13:17:36 +00002107- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002108 its argument, if it exists. If not, it will work like before. This
2109 allows customizing the output of dir() in the presence of a
2110 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002111
Collin Winter276887b2007-03-12 16:11:39 +00002112- Patch #922167: Python no longer segfaults when faced with infinitely

2119 parthensized forms. This means complex(repr(x)) now works instead of
2120 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002121
Georg Brandlaa2321b2007-03-07 00:40:28 +00002122- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002123 makes the filenames the warning module prints much more sensible
2124 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002125

Georg Brandl0fca97a2007-03-05 22:28:08 +00002137- Patch #1674228: when assigning a slice (old-style), check for the
2138 sq_ass_slice instead of the sq_slice slot.
2139
Georg Brandl3ee81df2008-05-17 18:14:43 +00002140- When printing an unraisable error, don't print exceptions. before
2141 the name. This duplicates the behavior whening normally printing
2142 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002243 generator expressions (x for x, in ... ) works again. Fixing this
2244 problem required changing the .pyc magic number. This means that
2245 .pyc files generated before 2.5c2 will be regenerated.

2771 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003052- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3053 with RFC 3207 and forgets any knowledge obtained from the server not
3054 obtained from the TLS negotiation itself. Patch contributed by Bill
3055 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003058 that the SMTP.starttls() caller no longer needs to call ehlo()
3059 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003060 does not claim to support starttls. Adds the
3061 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3142 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3143 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003160 time so that opening a database previously created with the DB_DUP
3161 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3162 opens. Specifically: dictionary assignment to a DB object will
3163 replace all values for a given key when the database allows
3164 duplicate values. DB users should use DB.put(k, v) when they want
3165 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003166

3172 characters with ASCII value less than 32. Also, it correctly quotes
3173 dots only if they occur on a single line, as opposed to the previous
3174 behavior of quoting dots if they are the second character of any
3175 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003176

3498-----
3499
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Unified naming convention for free lists and their limits. All free
3501 lists in Object/ are named ``free_list``, the counter ``numfree``
3502 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3503 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3506 to ``PyTuple_SetItem``, it can be used to populate a brand new
3507 frozenset; but it does not steal a reference to the added item.

3512 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3513 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003514
3515- Patch #1720595: add T_BOOL to the range of structmember types.
3516
3517- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3518 ``PyFloat_GetInfo()`` to the float API.
3519
Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3521 of w# format code incorrectly truncated the length to an int, even
3522 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3523 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3526 Py_TYPE and Py_REFCNT.

3543- Fix some leftovers from the conversion from int to Py_ssize_t
3544 (relevant to strings and sequences of more than 2**31 items).
3545
3546- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3547 outside of pystate.c and should not be necessary.
3548
Georg Brandl3ee81df2008-05-17 18:14:43 +00003549- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3550 absolute imports. In earlier versions they might have used relative
3551 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003552
Georg Brandl3ee81df2008-05-17 18:14:43 +00003553- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3554 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003555
Georg Brandl3ee81df2008-05-17 18:14:43 +00003556- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003563- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3564 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3565 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3566 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003567

Georg Brandl3ee81df2008-05-17 18:14:43 +00003581- Removed the macfs module. It had been deprecated since Python 2.5.
3582 This lead to the deprecation of macostools.touched() as it relied
3583 solely on macfs and was a no-op under OS X.
