77
Vinay Sajip6badbe92009-01-20 22:49:13 +000078- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +000079 method on file objects with closefd=False. The file descriptor is still
80 kept open but the file object behaves like a closed file. The ``FileIO``

116 which inherited from numbers.py which did not have __slots__ defined. The

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

189 zipimport (or any other conformant PEP 302 loader). Original patch by

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

238
Benjamin Peterson866eba92008-11-19 22:05:53 +0000239- Issue #4348: Some bytearray methods returned that didn't cause any change to

525
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000526- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
527 PyString_FromFormat or PyErr_Format to display size_t values. The macro
528 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
529 ``printf`` function, whereas PyString_FromFormat has an independent
530 implementation and uses "%zd" on all platforms for size_t values.
531 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +0000552 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
553 mechanism. In the process, fix a bug where isinstance() and issubclass(),

643 non-integer floating point number.
644
Vinay Sajip65d66e12008-09-04 07:31:21 +0000645- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

Benjamin Peterson37346b22008-08-23 20:27:43 +0000648Extension Modules
649-----------------
650
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000651- Issue #2975: When compiling several extension modules with Visual Studio 2008
652 from the same python interpreter, some environment variables would grow
653 without limit.
654
Benjamin Peterson37346b22008-08-23 20:27:43 +0000655- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

662
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000663- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves
664 concurrent access to the same SQLite database from multiple
665 threads/processes.

671 wrapper for warnings.catch_warnings() that makes it easier to check
672 that expected warning messages are being reported.
673
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +0000674- Issue #3796: Some tests functions were not enabled in test_float.
675

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000692What's New in Python 2.6 beta 3?
693================================
694
Barry Warsaw07a4a382008-08-21 01:15:08 +0000695*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000696
697Core and Builtins
698-----------------
699
Guido van Rossumf8402962008-08-20 15:01:50 +0000700- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
701 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
702 extensions do not automatically benefit from the class attribute
703 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
704 to their tp_flags field if they care. This is a backwards
705 compatibility feature; in 3.0, all types will use the cache by
706 default.
707
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000708- Keyword arguments can now follow starred arguments. (``f(a, *args,
709 keyword=23)`` is now valid syntax.)
710
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000711- ctypes function pointers that are COM methods have a boolean True
712 value again.
713
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000714- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
715 by denying s# to parse objects that have a releasebuffer procedure,
716 and introducing s*.
717
Georg Brandl1e13ea92008-08-11 09:07:59 +0000718- Issue #3537: Fix an assertion failure when an empty but presized dict
719 object was stored in the freelist.
720
Mark Dickinsonb6467572008-08-04 21:30:09 +0000721- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
722 ValueError consistently across platforms.
723
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000724- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
725 (64bit Unix, for example), unichr() would truncate its argument and return
726 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
727
Neal Norwitze7d8be82008-07-31 17:17:14 +0000728- Apply security patches from Apple.
729
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000730- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
731 PyErr_ExceptionMatches returns 0 when an exception occurs there.
732
Antoine Pitrou92f82162008-07-25 22:22:08 +0000733- Issue #1819: function calls with several named parameters are now on
734 average 35% faster (as measured by pybench).
735
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000736- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
737 the python debugger steps into a class statement: the free variables (local
738 variables defined in an outer scope) would be deleted from the outer scope.
739
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000740- Issue #2620: Overflow checking when allocating or reallocating memory
741 was not always being done properly in some python types and extension
742 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
743 all been updated to perform better checks and places in the code that
744 would previously leak memory on the error path when such an allocation
745 failed have been fixed.
746
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000747Library
748-------
749

751
Benjamin Petersone977ad42008-08-20 01:42:01 +0000752- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
753 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
754
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000755- Issue #2234: distutils failed for some versions of the cygwin compiler. The
756 version reported by these tools does not necessarily follow the python
757 version numbering scheme, so the module is less strict when parsing it.
758
Nick Coghlanf70385a2008-08-18 12:42:46 +0000759- Issue #2235: Added Py3k warnings for types which will become unhashable
760 under the stricter __hash__ inheritance rules in 3.0. Several types
761 which did not meet the rules for hash invariants and were already
762 unhashable in 3.0 have now been explicitly flagged as unhashable in
763 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
764 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
765
Brett Cannon88f801d2008-08-18 00:46:22 +0000766- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

774
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000775- Issue #3575: Incremental decoder's decode function now takes bytearray
776 by using 's*' instead of 't#'.
777
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000778- Issue #2222: Fixed reference leak when occured os.rename()
779 fails unicode conversion on 2nd parameter. (windows only)
780
Facundo Batista94f243a2008-08-17 03:38:39 +0000781- Issue 2464. urllib2 now supports a malformation in the URL received
782 in a redirect.
783
Brett Cannonabe423e2008-08-16 21:47:07 +0000784- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000785 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000786
Facundo Batistaeb90b782008-08-16 14:44:07 +0000787- Issue #2776: fixed small issue when handling an URL with double slash
788 after a 302 response in the case of not going through a proxy.
789
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000790- Issue #2676: in the email package, content-type parsing was hanging on
791 pathological input because of quadratic or exponential behaviour of a
792 regular expression.
793
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000794- Issue #3476: binary buffered reading through the new "io" library is now
795 thread-safe.
796
Brett Cannonbf3157b2008-08-14 05:00:03 +0000797- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
798 since mimetools itself is deprecated. Because modules are cached, all
799 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
800
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000801- Issue #3134: shutil referenced undefined WindowsError symbol.
802
Robert Schuppenies14646332008-08-10 11:01:53 +0000803- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
804 menu entries were not deleted.
805
Brett Cannon83e81842008-08-09 23:30:55 +0000806- Copied the implementation of reduce() to _functools.reduce() to have a
807 version that did not raise a DeprecationWarning under -3.
808
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000809- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
810 a MemoryError rather than silently stop the iteration.
811
Guido van Rossum59ce9012008-08-09 14:55:34 +0000812- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
813 to _sre.compile() will now be rejected. This should not affect anybody
814 since the re.compile() function never generates invalid re-bytecode.
815
Skip Montanaroa032bf42008-08-08 22:52:51 +0000816- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
817 upon first access it can be automatically initialized from the csv file if
818 it wasn't initialized during instantiation.
819
Brett Cannon3aa2a492008-08-06 22:28:09 +0000820- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
821 the reload() built-in has been removed.
822
Brett Cannon7e30b672008-08-04 21:52:25 +0000823- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000824 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

826 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
827 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
828 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
829 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +0000830
Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000831- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
832 raised an AttributeError.
833
Benjamin Peterson01a24322008-07-28 23:35:27 +0000834- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000835 asking for a specific length. This problem only affected files opened
836 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000837

845
Georg Brandlf9efabb2008-07-23 15:16:45 +0000846- Deprecate the "ast" parser function aliases.
847
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000848- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.

860
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000861- Issue #3394: zipfile.writestr sets external attributes when passed a
862 file name rather than a ZipInfo instance, so files are extracted with
863 mode 0600 rather than 000 under Unix.
864
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000865- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
866 argument in python 2.5, this broke code that subclassed Popen to include its
867 own poll method. Fixed my moving _deadstate to an _internal_poll method.
868
Martin v. Löwis8dbf3642008-08-01 14:10:26 +0000869Build

875-------------
876
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000877- Issue #2235: the C API function PyObject_HashNotImplemented and its
878 interaction with the tp_hash slot (added in 2.6b2) are now documented
879

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

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000886What's New in Python 2.6 beta 2?
887================================
888
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000889*Release date: 17-Jul-2008*
890
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000891Core and Builtins
892-----------------
893
Georg Brandl3e483f62008-07-16 22:57:41 +0000894- Issue #3156: Fix inconsistent behavior of the bytearray type: all
895 its methods now allow for items objects that can be converted to
896 an integer using operator.index().
897
Mark Dickinson64b7e502008-07-16 09:40:03 +0000898- Issue #3360: Fix incorrect parsing of '020000000000.0', which
899 produced a ValueError instead of giving the correct float.
900
Eric Smitha5fa5a22008-07-16 00:11:49 +0000901- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
902 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
903
Mark Dickinson7103aa42008-07-15 19:08:33 +0000904- Issue #3008: the float type has a new instance method 'float.hex'
905 and a new class method 'float.fromhex' to convert floating-point
906 numbers to and from hexadecimal strings, respectively.
907
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000908- Issue #2235: __hash__ is once again inherited by default. To allow
909 collections.Hashable to remain meaningful in the presence of the
910 default hash implementation (object.__hash__), it is now possible
911 to explicit block inheritance of hash by setting __hash__=None at
912 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
913 level.
914
Nick Coghlanb028f502008-07-13 14:52:36 +0000915- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
916 the parent module cannot be found while performing an absolute import.
917 This means that an incorrectly defined __package__ attribute will
918 now only prevent relative imports in that module rather than causing
919 all imports from that module to fail.
920
Nick Coghlan14ff9942008-07-08 14:21:42 +0000921- Issue #2517: Allow unicode messages in Exceptions again by correctly
922 bypassing the instance dictionary when looking up __unicode__ on
923 new-style classes.
924
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000925- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
926 set to a custom object whose write() method happens to install
927 another file in sys.stdout.
928
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000929- Issue #3088: Corrected a race condition in classes derived from
930 threading.local: the first member set by a thread could be saved in
931 another thread's dictionary.
932
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000933- Issue #3004: Minor change to slice.indices(): the start and stop
934 arguments are now treated identically, making the behaviour easier
935 to describe and understand. For example, slice(None, -10,
936 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
937 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
938 10, -1).
939

Georg Brandl5cc774e2008-06-11 20:28:06 +00001392 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001393
1394 This is controlled by the configure argument ``--with-universal-archs``:
1395

1397
1398 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1399
1400 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

1441 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00001442
Christian Heimese74c8f22008-04-19 02:23:57 +00001443- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001454- Issue #1631171: Re-implement the 'warnings' module in C (the
1455 original Python code has been kept as backup). This will allow for
1456 using the 'warning's machinery in such places as the parser where
1457 use of pure Python code is not possible. Both the ``showarning()``
1458 and ``formatwarning()`` gain an optional 'line' argument which is
1459 not called by default for backwards-compatibility reasons. Setting
1460 ``warnings.showwarning()`` to an implementation that lacks support
1461 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001486- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00001524- Issue #2550: The approach used by client/server code for obtaining
1525 ports to listen on in network-oriented tests has been refined in an
1526 effort to facilitate running multiple instances of the entire
1527 regression test suite in parallel without issue.
1528 test_support.bind_port() has been fixed such that it will always
1529 return a unique port -- which wasn't always the case with the
1530 previous implementation, especially if socket options had been set
1531 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1532 new implementation of bind_port() will actually raise an exception
1533 if it is passed an AF_INET/SOCK_STREAM socket with either the
1534 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1535 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1536 the socket it's been passed. This currently only applies to
1537 Windows. This option prevents any other sockets from binding to the
1538 host/port we've bound to, thus removing the possibility of the
1539 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1540 when a second SOCK_STREAM socket binds and accepts to a host/port
1541 that's already been bound by another socket. The optional preferred
1542 port parameter to bind_port() has been removed. Under no
1543 circumstances should tests be hard coding ports!
1544
1545 test_support.find_unused_port() has also been introduced, which will
1546 pass a temporary socket object to bind_port() in order to obtain an
1547 unused port. The temporary socket object is then closed and
1548 deleted, and the port is returned. This method should only be used
1549 for obtaining an unused port in order to pass to an external program
1550 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1551 a parameter to a server-oriented class that doesn't give you direct
1552 access to the underlying socket used.
1553
1554 Finally, test_support.HOST has been introduced, which should be used
1555 for the host argument of any relevant socket calls (i.e. bind and
1556 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001557
1558 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001559 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001560 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1561 test_asynchat and test_socket_ssl.
1562
Georg Brandl3ee81df2008-05-17 18:14:43 +00001563 It is now possible for multiple instances of the regression test
1564 suite to run in parallel without issue.

1831-----------------
1832
Fred Drakea8ee94b2008-03-01 02:45:07 +00001833- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001834 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00001836- Issue #2067: file.__exit__() now calls subclasses' close() method.
1837
1838- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001839
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001840- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001841 issue 215555 for a discussion.
1842
Eric Smitha73fbe72008-02-23 03:09:44 +00001843- Added the future_builtins module, which contains hex() and oct().
1844 These are the PEP 3127 version of these functions, designed to be
1845 compatible with the hex() and oct() builtins from Python 3.0. They
1846 differ slightly in their output formats from the existing, unchanged
1847 Python 2.6 builtins. The expected usage of the future_builtins
1848 module is:
1849 from future_builtins import hex, oct
1850
Eric Smith7ef40bf2008-02-20 23:34:22 +00001851- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1852 exponents for exponents with absolute value < 100. Follows C99
1853 standard. This is a change on Windows, which would use 3 digits.
1854 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1855 so that any alterations it does to the resulting string will be
1856 available in stringlib/formatter.h (for float.__format__).
1857
Eric Smith5a3c1352008-02-19 13:21:56 +00001858- Implemented PEP 3101, Advanced String Formatting. This adds a new
1859 builtin format(); a format() method for str and unicode; a
1860 __format__() method to object, str, unicode, int, long, float, and
1861 datetime; the class string.Formatter; and the C API
1862 PyObject_Format().
1863
Georg Brandl3ee81df2008-05-17 18:14:43 +00001864- Fixed several potential crashes, all caused by specially crafted
1865 __del__ methods exploiting objects in temporarily inconsistent
1866 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001867
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001868- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001869 prevent a possible crash: an Abstract Base Class would try to access
1870 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001871
Georg Brandl3ee81df2008-05-17 18:14:43 +00001872- Fixed repr() and str() of complex numbers with infinity or nan as
1873 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001874
Georg Brandl3ee81df2008-05-17 18:14:43 +00001875- Clear all free lists during a gc.collect() of the highest generation
1876 in order to allow pymalloc to free more arenas. Python may give back
1877 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001878
Georg Brandl3ee81df2008-05-17 18:14:43 +00001879- Issue #2045: Fix an infinite recursion triggered when printing a
1880 subclass of collections.defaultdict, if its default_factory is set
1881 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001882
Christian Heimesf75dbef2008-02-08 00:11:31 +00001883- Fixed a minor memory leak in dictobject.c. The content of the free
1884 list was not freed on interpreter shutdown.
1885
Georg Brandl3ee81df2008-05-17 18:14:43 +00001886- Limit free list of method and builtin function objects to 256
1887 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001888
Georg Brandl3ee81df2008-05-17 18:14:43 +00001889- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1890 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001891 to compact the internal free lists of pre-allocted ints and floats.
1892
Georg Brandl3ee81df2008-05-17 18:14:43 +00001893- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1894 calls. Python expected the return type int but the fork familie
1895 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001896
Georg Brandl3ee81df2008-05-17 18:14:43 +00001897- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1898 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001899
Georg Brandl3ee81df2008-05-17 18:14:43 +00001900- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1901 with the collections.Sequence API.

1907 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001908
Georg Brandl3ee81df2008-05-17 18:14:43 +00001909- Patch #1473257: generator objects gain a gi_code attribute. This is
1910 the same object as the func_code attribute of the function that
1911 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001912
Georg Brandl3ee81df2008-05-17 18:14:43 +00001913- Issue #1920: "while 0" statements were completely removed by the
1914 compiler, even in the presence of an "else" clause, which is
1915 supposed to be run when the condition is false. Now the compiler
1916 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001917
Guido van Rossumeead05f2008-01-24 18:21:02 +00001918- A few crashers fixed: weakref_in_del.py (issue #1377858);
1919 loosing_dict_ref.py (issue #1303614, test67.py);
1920 borrowed_ref_[34].py (not in tracker).
1921
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001922- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001923 suppressed while an extension is loaded by calling SetErrorMode in
1924 dynload_win.c. The error is still reported properly.
1925
Georg Brandl3ee81df2008-05-17 18:14:43 +00001926- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001927 several extension methods and modules do not work without unicode
1928 support.
1929
Georg Brandl26543b12008-01-21 18:36:51 +00001930- Issue #1882: when compiling code from a string, encoding cookies in the
1931 second line of code were not always recognized correctly.
1932
Georg Brandl14404b62008-01-19 19:27:05 +00001933- Issue #1679: "0x" was taken as a valid integer literal.
1934
Georg Brandl6caad7d2008-01-26 14:19:22 +00001935- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001936 added.
1937
Christian Heimesc94e2b52008-01-14 04:13:37 +00001938- sys.float_info / PyFloat_GetInfo: The floating point information
1939 object was converted from a dict to a specialized structseq object.
1940
Georg Brandl3ee81df2008-05-17 18:14:43 +00001941- Patch #1816: Added sys.flags structseq. It exposes the status of
1942 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001943
Georg Brandl3ee81df2008-05-17 18:14:43 +00001944- Objects/structseq.c: Implemented new structseq representation. The

1946 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001947
Georg Brandl3ee81df2008-05-17 18:14:43 +00001948- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00001970 and INF. float("nan"), float("inf") and float("-inf") now work on
1971 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001972
Georg Brandl3ee81df2008-05-17 18:14:43 +00001973- Compiler now generates simpler and faster code for dictionary
1974 literals. The oparg for BUILD_MAP now indicates an estimated
1975 dictionary size. There is a new opcode, STORE_MAP, for adding
1976 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002005- Patch #1739468: Directories and zipfiles containing a __main__.py
2006 file can now be directly executed by passing their name to the
2007 interpreter. The directory/zipfile is automatically inserted as the
2008 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002010- Issue #1265: Fix a problem with sys.settrace, if the tracing
2011 function uses a generator expression when at the same time the
2012 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002013
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002014- sets and frozensets now have an isdisjoint() method.

2017
Neal Norwitz44f326e2007-10-05 05:29:17 +00002018- Fix warnings found by the new version of the Coverity checker.
2019
Georg Brandl3ee81df2008-05-17 18:14:43 +00002020- The enumerate() builtin function is no longer bounded to sequences
2021 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2022 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002023
Georg Brandl3ee81df2008-05-17 18:14:43 +00002024- Issue #1686386: Tuple's tp_repr did not take into account the
2025 possibility of having a self-referential tuple, which is possible
2026 from C code. Nor did object's tp_str consider that a type's tp_str
2027 could do something that could lead to an inifinite recursion.
2028 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2029 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002030
Georg Brandl3ee81df2008-05-17 18:14:43 +00002031- Issue #1164: It was possible to trigger deadlock when using the
2032 'print' statement to write to a file since the GIL was not released
2033 as needed. Now PyObject_Print() does the right thing along with
2034 various tp_print implementations of the built-in types and those in
2035 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002036
Georg Brandl3ee81df2008-05-17 18:14:43 +00002037- Issue #1147: Exceptions were directly allowing string exceptions in
2038 their throw() method even though string exceptions no longer
2039 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002041- Issue #1096: Prevent a segfault from getting the repr of a very
2042 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002043
Brett Cannon1e534b52007-09-07 04:18:30 +00002044- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002045 PyObject_Call() never calling back out to Python code to trigger
2046 recursion depth updates/checks. Required the creation of a static
2047 RuntimeError instance in case normalizing an exception put the
2048 recursion check value past its limit. Fixes crashers
2049 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002050

Neal Norwitz0ac60192007-05-27 04:08:54 +00002064- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002065 __*__ attributes. (Some already existed, e.g., __doc__ and
2066 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002067
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002068- Add -3 option to the interpreter to warn about features that are
2069 deprecated and will be changed/removed in Python 3.0.
2070
Georg Brandl2134e752007-05-21 20:34:16 +00002071- Patch #1686487: you can now pass any mapping after '**' in function
2072 calls.
2073
Collin Winter62903052007-05-18 23:11:24 +00002074- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002075 "except E as target:". This is to provide forwards compatibility
2076 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002077
Brett Cannon229cee22007-05-05 01:34:02 +00002078- Deprecate BaseException.message as per PEP 352.
2079
Georg Brandl3ee81df2008-05-17 18:14:43 +00002080- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002081 inherited from a builtin base.
2082
Vinay Sajip8549ce32007-05-06 17:53:37 +00002083- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002084 setting a plain string, ie don't expand to single letter identifiers.
2085
Raymond Hettinger13936692007-04-11 18:40:58 +00002086- Request #1191699: Slices can now be pickled.
2087
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002088- Request #1193128: str.translate() now allows a None argument for
2089 translations that only remove characters without re-mapping the
2090 remaining characters.
2091
Georg Brandl5cb76c12007-03-21 09:00:39 +00002092- Patch #1682205: a TypeError while unpacking an iterable is no longer
2093 masked by a generic one with the message "unpack non-sequence".
2094
Neal Norwitzaa754b72007-03-21 06:39:48 +00002095- Remove unused file Python/fmod.c.
2096
Guido van Rossum143b5642007-03-23 04:58:42 +00002097- Bug #1683368: The object.__init__() and object.__new__() methods are
2098 now stricter in rejecting excess arguments. The only time when
2099 either allows excess arguments is when it is not overridden and the
2100 other one is. For backwards compatibility, when both are
2101 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002102 warning later). Also, type.__init__() insists on the same signature
2103 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002104
Georg Brandl3ee81df2008-05-17 18:14:43 +00002105- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2106 object to complex using its __complex__() method before falling back
2107 to the __float__() method. Therefore, the functions in the cmath
2108 module now can operate on objects that define a __complex__()
2109 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002110
Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Patch #1623563: allow __class__ assignment for classes with
2112 __slots__. The old and the new class are still required to have the
2113 same slot names.

2119 ``object.__reduce_ex__()`` is called with an object that is faking
2120 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002121
Georg Brandl3ee81df2008-05-17 18:14:43 +00002122- Patch #1680015: Don't modify __slots__ tuple if it contains an

2126
Georg Brandl7b9c5552007-03-12 14:30:05 +00002127- Bug #1678647: write a newline after printing an exception in any
2128 case, even when converting the value to a string failed.
2129
Georg Brandl871f1bc2007-03-12 13:17:36 +00002130- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002131 its argument, if it exists. If not, it will work like before. This
2132 allows customizing the output of dir() in the presence of a
2133 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002134
Collin Winter276887b2007-03-12 16:11:39 +00002135- Patch #922167: Python no longer segfaults when faced with infinitely
2136 self-recursive reload() calls (as reported by bug #742342).
2137

Georg Brandl3ee81df2008-05-17 18:14:43 +00002141- Patch #1491866: change the complex() constructor to allow
2142 parthensized forms. This means complex(repr(x)) now works instead of
2143 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002144
Georg Brandlaa2321b2007-03-07 00:40:28 +00002145- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002146 makes the filenames the warning module prints much more sensible
2147 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002148
Georg Brandl49aafc92007-03-07 00:34:46 +00002149- Variant of patch #697613: don't exit the interpreter on a SystemExit
2150 exception if the -i command line option or PYTHONINSPECT environment

Georg Brandl098cd692007-03-06 12:17:50 +00002159
Georg Brandl0fca97a2007-03-05 22:28:08 +00002160- Patch #1674228: when assigning a slice (old-style), check for the
2161 sq_ass_slice instead of the sq_slice slot.
2162
Georg Brandl3ee81df2008-05-17 18:14:43 +00002163- When printing an unraisable error, don't print exceptions. before
2164 the name. This duplicates the behavior whening normally printing
2165 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002166
Georg Brandl3ee81df2008-05-17 18:14:43 +00002167- Bug #1653736: Properly discard third argument to

2222
Armin Rigo7ccbca92006-10-04 12:17:45 +00002223- A number of places, including integer negation and absolute value,

Georg Brandl3ee81df2008-05-17 18:14:43 +00003075- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3076 with RFC 3207 and forgets any knowledge obtained from the server not
3077 obtained from the TLS negotiation itself. Patch contributed by Bill
3078 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003079
Georg Brandl3ee81df2008-05-17 18:14:43 +00003080- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003081 that the SMTP.starttls() caller no longer needs to call ehlo()
3082 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083 does not claim to support starttls. Adds the
3084 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00003139- itertools.chain() now has an alternate constructor,

3165 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3166 silently miscode subclasses of those types. Now, it raises a
3167 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003168

Georg Brandl3ee81df2008-05-17 18:14:43 +00003183 time so that opening a database previously created with the DB_DUP
3184 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3185 opens. Specifically: dictionary assignment to a DB object will
3186 replace all values for a given key when the database allows
3187 duplicate values. DB users should use DB.put(k, v) when they want
3188 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003189

3195 characters with ASCII value less than 32. Also, it correctly quotes
3196 dots only if they occur on a single line, as opposed to the previous
3197 behavior of quoting dots if they are the second character of any
3198 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003199

3521-----
3522
Georg Brandl3ee81df2008-05-17 18:14:43 +00003523- Unified naming convention for free lists and their limits. All free
3524 lists in Object/ are named ``free_list``, the counter ``numfree``
3525 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3526 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003527
Georg Brandl3ee81df2008-05-17 18:14:43 +00003528- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3529 to ``PyTuple_SetItem``, it can be used to populate a brand new

3542
Georg Brandl3ee81df2008-05-17 18:14:43 +00003543- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3544 of w# format code incorrectly truncated the length to an int, even
3545 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3546 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003547
Georg Brandl3ee81df2008-05-17 18:14:43 +00003548- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3568
3569- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3570 outside of pystate.c and should not be necessary.
3571
Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3573 absolute imports. In earlier versions they might have used relative
3574 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003575
Georg Brandl3ee81df2008-05-17 18:14:43 +00003576- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3577 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003578
Georg Brandl3ee81df2008-05-17 18:14:43 +00003579- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003604- Removed the macfs module. It had been deprecated since Python 2.5.
3605 This lead to the deprecation of macostools.touched() as it relied
3606 solely on macfs and was a no-op under OS X.
