25 an existing .py counterpart, override the co_filename attributes of all
26 code objects if the original filename is obsolete (which can happen if the
27 file has been renamed, moved, or if it is accessed through different paths).
28 Patch by Ziga Seilnacht and Jean-Paul Calderone.
29
Georg Brandl734373c2009-01-03 21:55:17 +000030- Issue #4075: Use OutputDebugStringW in Py_FatalError.

64
Vinay Sajip6badbe92009-01-20 22:49:13 +000065- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +000066 method on file objects with closefd=False. The file descriptor is still

80 inside its source path if it began with the same letters (e.g. "src" vs.
81 "src.new").
82
Raymond Hettingerc9794482009-01-28 23:14:58 +000083- Issue 4920: Fixed .next() vs .__next__() issues in the ABCs for

102
Raymond Hettinger825758c2009-01-08 05:20:19 +0000103- Issue 4816: itertools.combinations() and itertools.product were raising
104 a ValueError for values of *r* larger than the input iterable. They now
105 correctly return an empty iterator.
106
Raymond Hettinger8f726922009-01-03 09:27:41 +0000107- Fractions.from_float() no longer loses precision for integers too big to

Raymond Hettingerd263bd82008-12-31 04:18:44 +0000110- Issue 4790: The nsmallest() and nlargest() functions in the heapq module
111 did unnecessary work in the common case where no key function was specified.

131
132- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
133 302 conformant loader) will now work correctly in most cases (they
134 are still subject to the constraints that exist for all code running
135 from inside a module loaded via a PEP 302 loader and attempting to
136 perform IO operations based on __file__). Original patch by
137 Alexander Belopolsky.

454
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000455- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
456 PyString_FromFormat or PyErr_Format to display size_t values. The macro
457 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
458 ``printf`` function, whereas PyString_FromFormat has an independent
459 implementation and uses "%zd" on all platforms for size_t values.
460 This makes a difference on win64, where ``printf`` needs "%Id" to display
461 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000478 was correctly parsed but parsing of subsequent arguments failed.
479
Vinay Sajip35e3b032008-09-01 14:33:59 +0000480- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000481 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
482 mechanism. In the process, fix a bug where isinstance() and issubclass(),
483 when given a tuple of classes as second argument, were looking up
484 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
485 type object.

630 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
631 extensions do not automatically benefit from the class attribute
632 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
633 to their tp_flags field if they care. This is a backwards
634 compatibility feature; in 3.0, all types will use the cache by
635 default.
636
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000637- Keyword arguments can now follow starred arguments. (``f(a, *args,
638 keyword=23)`` is now valid syntax.)
639
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000640- ctypes function pointers that are COM methods have a boolean True
641 value again.
642
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000643- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
644 by denying s# to parse objects that have a releasebuffer procedure,
645 and introducing s*.
646
Georg Brandl1e13ea92008-08-11 09:07:59 +0000647- Issue #3537: Fix an assertion failure when an empty but presized dict
648 object was stored in the freelist.
649
Mark Dickinsonb6467572008-08-04 21:30:09 +0000650- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
651 ValueError consistently across platforms.
652
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000653- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
654 (64bit Unix, for example), unichr() would truncate its argument and return
655 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
656
Neal Norwitze7d8be82008-07-31 17:17:14 +0000657- Apply security patches from Apple.
658
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000659- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
660 PyErr_ExceptionMatches returns 0 when an exception occurs there.
661
Antoine Pitrou92f82162008-07-25 22:22:08 +0000662- Issue #1819: function calls with several named parameters are now on
663 average 35% faster (as measured by pybench).
664
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000665- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
666 the python debugger steps into a class statement: the free variables (local
667 variables defined in an outer scope) would be deleted from the outer scope.
668
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000669- Issue #2620: Overflow checking when allocating or reallocating memory
670 was not always being done properly in some python types and extension
671 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
672 all been updated to perform better checks and places in the code that
673 would previously leak memory on the error path when such an allocation
674 failed have been fixed.

680
Benjamin Petersone977ad42008-08-20 01:42:01 +0000681- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
682 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
683
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000684- Issue #2234: distutils failed for some versions of the cygwin compiler. The
685 version reported by these tools does not necessarily follow the python
686 version numbering scheme, so the module is less strict when parsing it.
687
Nick Coghlanf70385a2008-08-18 12:42:46 +0000688- Issue #2235: Added Py3k warnings for types which will become unhashable
689 under the stricter __hash__ inheritance rules in 3.0. Several types
690 which did not meet the rules for hash invariants and were already
691 unhashable in 3.0 have now been explicitly flagged as unhashable in
692 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
693 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
694
Brett Cannon88f801d2008-08-18 00:46:22 +0000695- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

703
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000704- Issue #3575: Incremental decoder's decode function now takes bytearray
705 by using 's*' instead of 't#'.
706
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000707- Issue #2222: Fixed reference leak when occured os.rename()
708 fails unicode conversion on 2nd parameter. (windows only)
709
Facundo Batista94f243a2008-08-17 03:38:39 +0000710- Issue 2464. urllib2 now supports a malformation in the URL received

717 after a 302 response in the case of not going through a proxy.
718
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000719- Issue #2676: in the email package, content-type parsing was hanging on
720 pathological input because of quadratic or exponential behaviour of a
721 regular expression.
722
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000723- Issue #3476: binary buffered reading through the new "io" library is now
724 thread-safe.
725
Brett Cannonbf3157b2008-08-14 05:00:03 +0000726- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
727 since mimetools itself is deprecated. Because modules are cached, all
728 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
729
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000730- Issue #3134: shutil referenced undefined WindowsError symbol.
731
Robert Schuppenies14646332008-08-10 11:01:53 +0000732- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
733 menu entries were not deleted.
734
Brett Cannon83e81842008-08-09 23:30:55 +0000735- Copied the implementation of reduce() to _functools.reduce() to have a
736 version that did not raise a DeprecationWarning under -3.
737
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000738- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
739 a MemoryError rather than silently stop the iteration.
740
Guido van Rossum59ce9012008-08-09 14:55:34 +0000741- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
742 to _sre.compile() will now be rejected. This should not affect anybody
743 since the re.compile() function never generates invalid re-bytecode.
744
Skip Montanaroa032bf42008-08-08 22:52:51 +0000745- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
746 upon first access it can be automatically initialized from the csv file if
747 it wasn't initialized during instantiation.
748
Brett Cannon3aa2a492008-08-06 22:28:09 +0000749- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
750 the reload() built-in has been removed.
751
Brett Cannon7e30b672008-08-04 21:52:25 +0000752- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000753 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +0000764 asking for a specific length. This problem only affected files opened
765 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000766

789
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000790- Issue #3394: zipfile.writestr sets external attributes when passed a
791 file name rather than a ZipInfo instance, so files are extracted with
792 mode 0600 rather than 000 under Unix.
793
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000794- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
795 argument in python 2.5, this broke code that subclassed Popen to include its
796 own poll method. Fixed my moving _deadstate to an _internal_poll method.
797

807 interaction with the tp_hash slot (added in 2.6b2) are now documented
808
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000809- Issue #643841: The language reference now provides more detailed
810 coverage of the lookup process for special methods. The disclaimers
811 regarding lack of coverage of new-style classes have also been
812 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000818*Release date: 17-Jul-2008*
819
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000820Core and Builtins
821-----------------
822
Georg Brandl3e483f62008-07-16 22:57:41 +0000823- Issue #3156: Fix inconsistent behavior of the bytearray type: all
824 its methods now allow for items objects that can be converted to
825 an integer using operator.index().
826
Mark Dickinson64b7e502008-07-16 09:40:03 +0000827- Issue #3360: Fix incorrect parsing of '020000000000.0', which
828 produced a ValueError instead of giving the correct float.
829
Eric Smitha5fa5a22008-07-16 00:11:49 +0000830- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
831 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
832
Mark Dickinson7103aa42008-07-15 19:08:33 +0000833- Issue #3008: the float type has a new instance method 'float.hex'
834 and a new class method 'float.fromhex' to convert floating-point
835 numbers to and from hexadecimal strings, respectively.
836
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000837- Issue #2235: __hash__ is once again inherited by default. To allow
838 collections.Hashable to remain meaningful in the presence of the
839 default hash implementation (object.__hash__), it is now possible
840 to explicit block inheritance of hash by setting __hash__=None at
841 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
842 level.
843
Nick Coghlanb028f502008-07-13 14:52:36 +0000844- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
845 the parent module cannot be found while performing an absolute import.
846 This means that an incorrectly defined __package__ attribute will
847 now only prevent relative imports in that module rather than causing
848 all imports from that module to fail.
849
Nick Coghlan14ff9942008-07-08 14:21:42 +0000850- Issue #2517: Allow unicode messages in Exceptions again by correctly
851 bypassing the instance dictionary when looking up __unicode__ on
852 new-style classes.
853
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000854- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
855 set to a custom object whose write() method happens to install
856 another file in sys.stdout.
857
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000858- Issue #3088: Corrected a race condition in classes derived from
859 threading.local: the first member set by a thread could be saved in
860 another thread's dictionary.
861
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000862- Issue #3004: Minor change to slice.indices(): the start and stop
863 arguments are now treated identically, making the behaviour easier
864 to describe and understand. For example, slice(None, -10,
865 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
866 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
867 10, -1).
868
Georg Brandl278fc502008-07-19 12:46:12 +0000869- Issue #3219: Calling a function with repeated keyword arguments,
870 f(a=2, a=23), would not cause a syntax error. This was a regression
871 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000872
Georg Brandl278fc502008-07-19 12:46:12 +0000873- Issue #2862: Make int and float freelist management consistent with
874 other freelists. Changes their CompactFreeList apis into
875 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +0000876

878-------
879
Thomas Heller57adf222008-08-14 19:10:48 +0000880- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
881 api functions without holding the GIL, which could lead to a fatal
882 error when they failed.
883
Martin v. Löwisaabf4042008-08-02 07:20:25 +0000884- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

893 ForkingPickler.register() to resolve conflict with ctypes.
894
Vinay Sajip51e65192008-07-18 09:01:10 +0000895- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +0000896
Thomas Heller880f5292008-07-15 19:39:38 +0000897- Issue #3313: Fixed a crash when a failed dlopen() call does not set
898 a valid dlerror() message.
899
Thomas Heller2bad6572008-07-15 17:19:50 +0000900- Issue #3258: Fixed a crash when a ctypes POINTER type to an
901 incomplete structure was created.
902
Brett Cannon3d0b9f02008-07-13 01:15:07 +0000903- Issue #3339: dummy_thread.acquire() should not return None.

906
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +0000907- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +0000908
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +0000909- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
910 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +0000911 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +0000912 content-length. The problem had been corrected in the 2.4 branch, but never
913 merged into trunk.
914
Georg Brandle78fbcc2008-07-05 10:13:36 +0000915- Issue #2663: add filtering capability to shutil.copytree().

1320 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001321 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001322
1323 This is controlled by the configure argument ``--with-universal-archs``:
1324
1325 - ``--with-universal-archs=all``: install 4-way universal
1326
1327 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1328
1329 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1330
1331 This option should be used in combination with ``--enable-universalsdk=``.
1332
1333 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00001383- Issue #1631171: Re-implement the 'warnings' module in C (the
1384 original Python code has been kept as backup). This will allow for
1385 using the 'warning's machinery in such places as the parser where
1386 use of pure Python code is not possible. Both the ``showarning()``
1387 and ``formatwarning()`` gain an optional 'line' argument which is
1388 not called by default for backwards-compatibility reasons. Setting
1389 ``warnings.showwarning()`` to an implementation that lacks support
1390 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001453- Issue #2550: The approach used by client/server code for obtaining
1454 ports to listen on in network-oriented tests has been refined in an
1455 effort to facilitate running multiple instances of the entire
1456 regression test suite in parallel without issue.
1457 test_support.bind_port() has been fixed such that it will always
1458 return a unique port -- which wasn't always the case with the
1459 previous implementation, especially if socket options had been set
1460 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1461 new implementation of bind_port() will actually raise an exception
1462 if it is passed an AF_INET/SOCK_STREAM socket with either the
1463 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1464 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1465 the socket it's been passed. This currently only applies to
1466 Windows. This option prevents any other sockets from binding to the
1467 host/port we've bound to, thus removing the possibility of the
1468 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1469 when a second SOCK_STREAM socket binds and accepts to a host/port
1470 that's already been bound by another socket. The optional preferred
1471 port parameter to bind_port() has been removed. Under no
1472 circumstances should tests be hard coding ports!
1473
1474 test_support.find_unused_port() has also been introduced, which will
1475 pass a temporary socket object to bind_port() in order to obtain an
1476 unused port. The temporary socket object is then closed and
1477 deleted, and the port is returned. This method should only be used
1478 for obtaining an unused port in order to pass to an external program
1479 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1480 a parameter to a server-oriented class that doesn't give you direct
1481 access to the underlying socket used.
1482
1483 Finally, test_support.HOST has been introduced, which should be used
1484 for the host argument of any relevant socket calls (i.e. bind and
1485 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001486
1487 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001488 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001489 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1490 test_asynchat and test_socket_ssl.

1759Core and builtins
1760-----------------
1761
Fred Drakea8ee94b2008-03-01 02:45:07 +00001762- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001763 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001764
Georg Brandlad61bc82008-02-23 15:11:18 +00001765- Issue #2067: file.__exit__() now calls subclasses' close() method.
1766
1767- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001768
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001769- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001770 issue 215555 for a discussion.
1771
Eric Smitha73fbe72008-02-23 03:09:44 +00001772- Added the future_builtins module, which contains hex() and oct().
1773 These are the PEP 3127 version of these functions, designed to be
1774 compatible with the hex() and oct() builtins from Python 3.0. They
1775 differ slightly in their output formats from the existing, unchanged
1776 Python 2.6 builtins. The expected usage of the future_builtins
1777 module is:
1778 from future_builtins import hex, oct
1779
Eric Smith7ef40bf2008-02-20 23:34:22 +00001780- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1781 exponents for exponents with absolute value < 100. Follows C99
1782 standard. This is a change on Windows, which would use 3 digits.
1783 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1784 so that any alterations it does to the resulting string will be
1785 available in stringlib/formatter.h (for float.__format__).
1786
Eric Smith5a3c1352008-02-19 13:21:56 +00001787- Implemented PEP 3101, Advanced String Formatting. This adds a new
1788 builtin format(); a format() method for str and unicode; a
1789 __format__() method to object, str, unicode, int, long, float, and
1790 datetime; the class string.Formatter; and the C API
1791 PyObject_Format().
1792
Georg Brandl3ee81df2008-05-17 18:14:43 +00001793- Fixed several potential crashes, all caused by specially crafted
1794 __del__ methods exploiting objects in temporarily inconsistent
1795 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001796
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001797- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001798 prevent a possible crash: an Abstract Base Class would try to access
1799 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001800
Georg Brandl3ee81df2008-05-17 18:14:43 +00001801- Fixed repr() and str() of complex numbers with infinity or nan as
1802 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001803
Georg Brandl3ee81df2008-05-17 18:14:43 +00001804- Clear all free lists during a gc.collect() of the highest generation
1805 in order to allow pymalloc to free more arenas. Python may give back
1806 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001807
Georg Brandl3ee81df2008-05-17 18:14:43 +00001808- Issue #2045: Fix an infinite recursion triggered when printing a
1809 subclass of collections.defaultdict, if its default_factory is set
1810 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001811
Christian Heimesf75dbef2008-02-08 00:11:31 +00001812- Fixed a minor memory leak in dictobject.c. The content of the free
1813 list was not freed on interpreter shutdown.
1814
Georg Brandl3ee81df2008-05-17 18:14:43 +00001815- Limit free list of method and builtin function objects to 256
1816 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001817
Georg Brandl3ee81df2008-05-17 18:14:43 +00001818- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1819 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001820 to compact the internal free lists of pre-allocted ints and floats.
1821
Georg Brandl3ee81df2008-05-17 18:14:43 +00001822- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1823 calls. Python expected the return type int but the fork familie
1824 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001825
Georg Brandl3ee81df2008-05-17 18:14:43 +00001826- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1827 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001828
Georg Brandl3ee81df2008-05-17 18:14:43 +00001829- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1830 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001831
Georg Brandl3ee81df2008-05-17 18:14:43 +00001832- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
1833 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00001834
Georg Brandl3ee81df2008-05-17 18:14:43 +00001835- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1836 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001837
Georg Brandl3ee81df2008-05-17 18:14:43 +00001838- Patch #1473257: generator objects gain a gi_code attribute. This is
1839 the same object as the func_code attribute of the function that
1840 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001841
Georg Brandl3ee81df2008-05-17 18:14:43 +00001842- Issue #1920: "while 0" statements were completely removed by the
1843 compiler, even in the presence of an "else" clause, which is
1844 supposed to be run when the condition is false. Now the compiler
1845 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001846
Guido van Rossumeead05f2008-01-24 18:21:02 +00001847- A few crashers fixed: weakref_in_del.py (issue #1377858);
1848 loosing_dict_ref.py (issue #1303614, test67.py);
1849 borrowed_ref_[34].py (not in tracker).
1850
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001851- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001852 suppressed while an extension is loaded by calling SetErrorMode in
1853 dynload_win.c. The error is still reported properly.
1854
Georg Brandl3ee81df2008-05-17 18:14:43 +00001855- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001856 several extension methods and modules do not work without unicode
1857 support.
1858
Georg Brandl26543b12008-01-21 18:36:51 +00001859- Issue #1882: when compiling code from a string, encoding cookies in the
1860 second line of code were not always recognized correctly.
1861
Georg Brandl14404b62008-01-19 19:27:05 +00001862- Issue #1679: "0x" was taken as a valid integer literal.
1863
Georg Brandl6caad7d2008-01-26 14:19:22 +00001864- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001865 added.
1866
Christian Heimesc94e2b52008-01-14 04:13:37 +00001867- sys.float_info / PyFloat_GetInfo: The floating point information
1868 object was converted from a dict to a specialized structseq object.
1869
Georg Brandl3ee81df2008-05-17 18:14:43 +00001870- Patch #1816: Added sys.flags structseq. It exposes the status of
1871 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001872
Georg Brandl3ee81df2008-05-17 18:14:43 +00001873- Objects/structseq.c: Implemented new structseq representation. The
1874 patch makes structseqs (e.g. the return value of os.stat) more
1875 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001876
Georg Brandl3ee81df2008-05-17 18:14:43 +00001877- Patch #1700288: added a type attribute cache that caches method
1878 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00001879
Neal Norwitz3fc15b82008-01-10 05:42:58 +00001880- Bug #1776: __import__() no longer accepts filenames on any platform.
1881 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00001882
Georg Brandlaed6c662008-01-07 17:25:53 +00001883- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
1884
Georg Brandl3ee81df2008-05-17 18:14:43 +00001885- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
1886 envvar and sys.dont_write_bytecode attribute. All these can be set
1887 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00001888
Georg Brandl3ee81df2008-05-17 18:14:43 +00001889- Improve some exception messages when Windows fails to load an
1890 extension module. Now we get for example '%1 is not a valid Win32
1891 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00001892
Georg Brandl3ee81df2008-05-17 18:14:43 +00001893- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001895- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
1896 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00001897
Christian Heimes0a8143f2007-12-18 23:22:54 +00001898- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00001899 and INF. float("nan"), float("inf") and float("-inf") now work on
1900 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001901
Georg Brandl3ee81df2008-05-17 18:14:43 +00001902- Compiler now generates simpler and faster code for dictionary
1903 literals. The oparg for BUILD_MAP now indicates an estimated
1904 dictionary size. There is a new opcode, STORE_MAP, for adding
1905 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00001906
Georg Brandl3ee81df2008-05-17 18:14:43 +00001907- Issue #1638: %zd configure test fails on Linux.

1923 running, and if the deallocation of its frames somehow calls the
1924 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00001925

1935 file can now be directly executed by passing their name to the
1936 interpreter. The directory/zipfile is automatically inserted as the
1937 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00001938
Georg Brandl3ee81df2008-05-17 18:14:43 +00001939- Issue #1265: Fix a problem with sys.settrace, if the tracing
1940 function uses a generator expression when at the same time the
1941 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00001942
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00001943- sets and frozensets now have an isdisjoint() method.
1944
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00001945- optimize the performance of builtin.sum().
1946
Neal Norwitz44f326e2007-10-05 05:29:17 +00001947- Fix warnings found by the new version of the Coverity checker.
1948
Georg Brandl3ee81df2008-05-17 18:14:43 +00001949- The enumerate() builtin function is no longer bounded to sequences
1950 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
1951 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00001952
Georg Brandl3ee81df2008-05-17 18:14:43 +00001953- Issue #1686386: Tuple's tp_repr did not take into account the
1954 possibility of having a self-referential tuple, which is possible
1955 from C code. Nor did object's tp_str consider that a type's tp_str
1956 could do something that could lead to an inifinite recursion.
1957 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
1958 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00001959
Georg Brandl3ee81df2008-05-17 18:14:43 +00001960- Issue #1164: It was possible to trigger deadlock when using the
1961 'print' statement to write to a file since the GIL was not released
1962 as needed. Now PyObject_Print() does the right thing along with
1963 various tp_print implementations of the built-in types and those in
1964 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00001965
Georg Brandl3ee81df2008-05-17 18:14:43 +00001966- Issue #1147: Exceptions were directly allowing string exceptions in
1967 their throw() method even though string exceptions no longer
1968 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00001969
Georg Brandl3ee81df2008-05-17 18:14:43 +00001970- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00001973- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00001974 PyObject_Call() never calling back out to Python code to trigger
1975 recursion depth updates/checks. Required the creation of a static
1976 RuntimeError instance in case normalizing an exception put the
1977 recursion check value past its limit. Fixes crashers
1978 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00001993- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00001994 __*__ attributes. (Some already existed, e.g., __doc__ and
1995 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00002004 "except E as target:". This is to provide forwards compatibility
2005 with Python 3.0.

2011
Vinay Sajip8549ce32007-05-06 17:53:37 +00002012- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002013 setting a plain string, ie don't expand to single letter identifiers.
2014
Raymond Hettinger13936692007-04-11 18:40:58 +00002015- Request #1191699: Slices can now be pickled.

2025
Guido van Rossum143b5642007-03-23 04:58:42 +00002026- Bug #1683368: The object.__init__() and object.__new__() methods are
2027 now stricter in rejecting excess arguments. The only time when
2028 either allows excess arguments is when it is not overridden and the
2029 other one is. For backwards compatibility, when both are
2030 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002031 warning later). Also, type.__init__() insists on the same signature
2032 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002033
Georg Brandl3ee81df2008-05-17 18:14:43 +00002034- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2035 object to complex using its __complex__() method before falling back
2036 to the __float__() method. Therefore, the functions in the cmath
2037 module now can operate on objects that define a __complex__()
2038 method.

2055
Georg Brandl7b9c5552007-03-12 14:30:05 +00002056- Bug #1678647: write a newline after printing an exception in any
2057 case, even when converting the value to a string failed.
2058
Georg Brandl871f1bc2007-03-12 13:17:36 +00002059- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002060 its argument, if it exists. If not, it will work like before. This
2061 allows customizing the output of dir() in the presence of a
2062 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002063
Collin Winter276887b2007-03-12 16:11:39 +00002064- Patch #922167: Python no longer segfaults when faced with infinitely
2065 self-recursive reload() calls (as reported by bug #742342).

2072 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002073
Georg Brandlaa2321b2007-03-07 00:40:28 +00002074- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002075 makes the filenames the warning module prints much more sensible
2076 when a PYTHONSTARTUP file is used.

2090 sq_ass_slice instead of the sq_slice slot.
2091
Georg Brandl3ee81df2008-05-17 18:14:43 +00002092- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00002718- unittest now verifies more of its assumptions. In particular,
2719 TestCase and TestSuite subclasses (not instances) are no longer
2720 accepted in TestSuite.addTest(). This should cause no
2721 incompatibility since it never made sense with ordinary subclasses
2722 -- the failure just occurred later, with a more cumbersome
2723 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003004- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3005 with RFC 3207 and forgets any knowledge obtained from the server not
3006 obtained from the TLS negotiation itself. Patch contributed by Bill
3007 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003008
Georg Brandl3ee81df2008-05-17 18:14:43 +00003009- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003010 that the SMTP.starttls() caller no longer needs to call ehlo()
3011 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003012 does not claim to support starttls. Adds the
3013 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3094 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3095 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003112 time so that opening a database previously created with the DB_DUP
3113 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3114 opens. Specifically: dictionary assignment to a DB object will
3115 replace all values for a given key when the database allows
3116 duplicate values. DB users should use DB.put(k, v) when they want
3117 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003118

3124 characters with ASCII value less than 32. Also, it correctly quotes
3125 dots only if they occur on a single line, as opposed to the previous
3126 behavior of quoting dots if they are the second character of any
3127 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003457- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3458 to ``PyTuple_SetItem``, it can be used to populate a brand new
3459 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003463- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3464 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3465 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003466
3467- Patch #1720595: add T_BOOL to the range of structmember types.
3468
3469- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and

3471
Georg Brandl3ee81df2008-05-17 18:14:43 +00003472- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3473 of w# format code incorrectly truncated the length to an int, even
3474 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3475 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003476
Georg Brandl3ee81df2008-05-17 18:14:43 +00003477- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3478 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- PEP 3123: Provide forward compatibility with Python 3.0, while
3481 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3482 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003483
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3485 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003486
3487- Patch #1733960: Allow T_LONGLONG to accept ints.
3488
3489- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3490
Christian Heimes000a0742008-01-03 22:16:32 +00003491- Added a new API function ``PyImport_ImportModuleNoBlock``.
3492
Georg Brandl6caad7d2008-01-26 14:19:22 +00003493- Bug #1637022: Prefix AST symbols with _Py_.
3494
3495- Fix some leftovers from the conversion from int to Py_ssize_t
3496 (relevant to strings and sequences of more than 2**31 items).
3497
3498- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3499 outside of pystate.c and should not be necessary.
3500
Georg Brandl3ee81df2008-05-17 18:14:43 +00003501- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3502 absolute imports. In earlier versions they might have used relative
3503 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3506 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003507
Georg Brandl3ee81df2008-05-17 18:14:43 +00003508- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003515- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3516 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3517 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3518 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003519

Brett Cannon791d56f2007-05-31 19:40:42 +00003531- buildtools now raises a DeprecationWarning.
3532
Georg Brandl3ee81df2008-05-17 18:14:43 +00003533- Removed the macfs module. It had been deprecated since Python 2.5.
3534 This lead to the deprecation of macostools.touched() as it relied
3535 solely on macfs and was a no-op under OS X.
