Antoine Pitrou19fec8b2009-01-21 00:56:37 +0000310- Issue #5008: When a file is opened in append mode with the new IO library,
311 do an explicit seek to the end of file (so that e.g. tell() returns the

509What's New in Python 2.6.1
510==========================
511
512*Release date: 04-Dec-2008*
513
514Core and Builtins
515-----------------
516
517- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
518 interpreter to abort ("Fatal Python error: Could not reset the stack!")
519 instead of throwing a MemoryError.
520
521- Issue #4367: Python would segfault during compiling when the unicodedata
522 module couldn't be imported and \N escapes were present.
523
524- Issue #4348: Some bytearray methods returned that didn't cause any change to
525 the bytearray, returned the same bytearray instead of a copy.
526
527- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
528
529- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
530
531- Issue #4048: The parser module now correctly validates relative imports.
532
533- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
534 exec statement.
535
536- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
537 method does not return iterators for the 4th and 5th items.
538
539- Issue #4209: Enabling unicode_literals and the print_function in the same
540 __future__ import didn't work.
541
542- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
543 returned a path longer than MAX_PATH. (But It's doubtful this code path is
544 really executed because I cannot move to such directory on win2k)
545
546- Issue #4069: When set.remove(element) is used with a set element, the element
547 is temporarily replaced with an equivalent frozenset. But the eventual
548 KeyError would always report the empty frozenset([]) as the missing key. Now
549 it correctly refers to the initial element.
550
551- Fixed C99 style comments in several files. Python is now C89 compatible
552 again.

679- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
680 AttributeError instead of RuntimeError, depending in which C API call
681 exactly the recursion limit is exceeded. Consequently, both exception types
682 are caught and silenced.

698
Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000699- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
700
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000701- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
702 PyString_FromFormat or PyErr_Format to display size_t values. The macro
703 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
704 ``printf`` function, whereas PyString_FromFormat has an independent
705 implementation and uses "%zd" on all platforms for size_t values.
706 This makes a difference on win64, where ``printf`` needs "%Id" to display
707 64bit values.
708
Benjamin Peterson97179b02008-09-09 20:55:01 +0000709- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
710 error.
711
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000712- Issue #3777: long() applied to a float object now always return a long
713 object; previously an int would be returned for small values. the __long__
714 method is allowed to return either an int or a long, but the behaviour of
715 float objects should not change to respect backward compatibility.
716
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000717- Issue #3751: str.rpartition would perform a left-partition when called with
718 a unicode argument.
719
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000720- Issue #3683: Fix compilation when --without-threads is given.
721
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000722- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000723 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000724 was correctly parsed but parsing of subsequent arguments failed.
725
Vinay Sajip35e3b032008-09-01 14:33:59 +0000726- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000727 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
728 mechanism. In the process, fix a bug where isinstance() and issubclass(),
729 when given a tuple of classes as second argument, were looking up
730 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
731 type object.
732
Neal Norwitz18aa3882008-08-24 05:04:52 +0000733- Fix crashes on memory allocation failure found with failmalloc.
734
735- Fix memory leaks found with valgrind and update suppressions file.
736
737- Fix compiler warnings in opt mode which would lead to invalid memory reads.
738
739- Fix problem using wrong name in decimal module reported by pychecker.
740
Christian Heimes7d4c3172008-08-22 19:47:25 +0000741- Silenced another compiler warning about a used but not defined
742 function 'stringlib_contains_obj'.
743
Benjamin Peterson712ee922008-08-24 18:10:20 +0000744- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
745 ``__delslice__``.
746
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +0000747- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
748 library targets in the Makefile.
749
Gregory P. Smith980b99b2008-09-07 05:15:18 +0000750- Issue #1204: The configure script now tests for additional libraries
751 that may be required when linking against readline. This fixes issues
752 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

768
Nick Coghland2e09382008-09-11 12:11:06 +0000769- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
770 silent misbehaviour when a single instance is nested in multiple
771 with statements, or when the methods are invoked in the wrong order.
772
Vinay Sajip844f7412008-09-09 13:42:08 +0000773- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

799 path to the Python binary.
800
Brett Cannon1eaf0742008-09-02 01:25:16 +0000801- Issue 3602: Moved test.test_support.catch_warning() to
802 warnings.catch_warnings() along with some API cleanup. Expanding the tests
803 for catch_warnings() also led to an improvement in the raising of a
804 DeprecationWarning related to warnings.warn_explicit().
805
Benjamin Peterson973e6c22008-09-01 23:12:58 +0000806- The deprecation warnings for the old camelCase threading API were removed.
807

Benjamin Peterson37346b22008-08-23 20:27:43 +0000823Extension Modules
824-----------------
825
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000826- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000867What's New in Python 2.6 beta 3?
868================================
869
Barry Warsaw07a4a382008-08-21 01:15:08 +0000870*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000871
872Core and Builtins
873-----------------
874
Guido van Rossumf8402962008-08-20 15:01:50 +0000875- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
876 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
877 extensions do not automatically benefit from the class attribute
878 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
879 to their tp_flags field if they care. This is a backwards
880 compatibility feature; in 3.0, all types will use the cache by
881 default.
882
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000883- Keyword arguments can now follow starred arguments. (``f(a, *args,
884 keyword=23)`` is now valid syntax.)
885
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000886- ctypes function pointers that are COM methods have a boolean True
887 value again.
888
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000889- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
890 by denying s# to parse objects that have a releasebuffer procedure,
891 and introducing s*.
892
Georg Brandl1e13ea92008-08-11 09:07:59 +0000893- Issue #3537: Fix an assertion failure when an empty but presized dict
894 object was stored in the freelist.
895
Mark Dickinsonb6467572008-08-04 21:30:09 +0000896- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
897 ValueError consistently across platforms.
898
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000899- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
900 (64bit Unix, for example), unichr() would truncate its argument and return
901 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
902
Neal Norwitze7d8be82008-07-31 17:17:14 +0000903- Apply security patches from Apple.
904
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000905- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
906 PyErr_ExceptionMatches returns 0 when an exception occurs there.
907
Antoine Pitrou92f82162008-07-25 22:22:08 +0000908- Issue #1819: function calls with several named parameters are now on
909 average 35% faster (as measured by pybench).
910
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000911- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
912 the python debugger steps into a class statement: the free variables (local
913 variables defined in an outer scope) would be deleted from the outer scope.
914
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000915- Issue #2620: Overflow checking when allocating or reallocating memory
916 was not always being done properly in some python types and extension
917 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
918 all been updated to perform better checks and places in the code that
919 would previously leak memory on the error path when such an allocation
920 failed have been fixed.

929
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000930- Issue #2234: distutils failed for some versions of the cygwin compiler. The
931 version reported by these tools does not necessarily follow the python
932 version numbering scheme, so the module is less strict when parsing it.
933
Nick Coghlanf70385a2008-08-18 12:42:46 +0000934- Issue #2235: Added Py3k warnings for types which will become unhashable
935 under the stricter __hash__ inheritance rules in 3.0. Several types
936 which did not meet the rules for hash invariants and were already
937 unhashable in 3.0 have now been explicitly flagged as unhashable in
938 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
939 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
940
Brett Cannon88f801d2008-08-18 00:46:22 +0000941- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

949
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000950- Issue #3575: Incremental decoder's decode function now takes bytearray
951 by using 's*' instead of 't#'.
952
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000953- Issue #2222: Fixed reference leak when occured os.rename()
954 fails unicode conversion on 2nd parameter. (windows only)
955
Facundo Batista94f243a2008-08-17 03:38:39 +0000956- Issue 2464. urllib2 now supports a malformation in the URL received
957 in a redirect.
958
Brett Cannonabe423e2008-08-16 21:47:07 +0000959- Silence the DeprecationWarning raised when importing mimetools in

Brett Cannonabe423e2008-08-16 21:47:07 +0000961
Facundo Batistaeb90b782008-08-16 14:44:07 +0000962- Issue #2776: fixed small issue when handling an URL with double slash
963 after a 302 response in the case of not going through a proxy.
964
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000965- Issue #2676: in the email package, content-type parsing was hanging on
966 pathological input because of quadratic or exponential behaviour of a
967 regular expression.
968
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000969- Issue #3476: binary buffered reading through the new "io" library is now
970 thread-safe.
971
Brett Cannonbf3157b2008-08-14 05:00:03 +0000972- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
973 since mimetools itself is deprecated. Because modules are cached, all
974 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
975
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000976- Issue #3134: shutil referenced undefined WindowsError symbol.
977
Robert Schuppenies14646332008-08-10 11:01:53 +0000978- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to

1067-----------------
1068
Georg Brandl3e483f62008-07-16 22:57:41 +00001069- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1070 its methods now allow for items objects that can be converted to
1071 an integer using operator.index().
1072
Mark Dickinson64b7e502008-07-16 09:40:03 +00001073- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1074 produced a ValueError instead of giving the correct float.
1075
Eric Smitha5fa5a22008-07-16 00:11:49 +00001076- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1077 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1078
Mark Dickinson7103aa42008-07-15 19:08:33 +00001079- Issue #3008: the float type has a new instance method 'float.hex'
1080 and a new class method 'float.fromhex' to convert floating-point
1081 numbers to and from hexadecimal strings, respectively.
1082
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001083- Issue #2235: __hash__ is once again inherited by default. To allow
1084 collections.Hashable to remain meaningful in the presence of the
1085 default hash implementation (object.__hash__), it is now possible
1086 to explicit block inheritance of hash by setting __hash__=None at
1087 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1088 level.
1089
Nick Coghlanb028f502008-07-13 14:52:36 +00001090- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1091 the parent module cannot be found while performing an absolute import.
1092 This means that an incorrectly defined __package__ attribute will
1093 now only prevent relative imports in that module rather than causing
1094 all imports from that module to fail.
1095
Nick Coghlan14ff9942008-07-08 14:21:42 +00001096- Issue #2517: Allow unicode messages in Exceptions again by correctly

1106 another thread's dictionary.
1107
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001108- Issue #3004: Minor change to slice.indices(): the start and stop
1109 arguments are now treated identically, making the behaviour easier
1110 to describe and understand. For example, slice(None, -10,
1111 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1112 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1113 10, -1).
1114
Georg Brandl278fc502008-07-19 12:46:12 +00001115- Issue #3219: Calling a function with repeated keyword arguments,
1116 f(a=2, a=23), would not cause a syntax error. This was a regression
1117 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00001119- Issue #2862: Make int and float freelist management consistent with
1120 other freelists. Changes their CompactFreeList apis into

1128 error when they failed.
1129
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001130- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001155- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1156 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001157 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001158 content-length. The problem had been corrected in the 2.4 branch, but never
1159 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001174- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1562
Brett Cannonb61d8012008-05-11 23:39:04 +00001563- ``Lib/lib-old`` is now added to sys.path.
1564
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001565- On MacOS X it is now possible to install the framework in 64-bit
1566 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001567 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001568
1569 This is controlled by the configure argument ``--with-universal-archs``:
1570
1571 - ``--with-universal-archs=all``: install 4-way universal
1572
1573 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1574
1575 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1576
1577 This option should be used in combination with ``--enable-universalsdk=``.
1578
1579 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00001588
1589- The PyString functions have been renamed to PyBytes. A batch of
1590 defines were added so that the linker still sees the original
1591 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001629- Issue #1631171: Re-implement the 'warnings' module in C (the
1630 original Python code has been kept as backup). This will allow for
1631 using the 'warning's machinery in such places as the parser where
1632 use of pure Python code is not possible. Both the ``showarning()``
1633 and ``formatwarning()`` gain an optional 'line' argument which is
1634 not called by default for backwards-compatibility reasons. Setting
1635 ``warnings.showwarning()`` to an implementation that lacks support
1636 for the ``line`` argument will raise a DeprecationWarning.

1660
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001661- The getpass module has been improved on Unix. It now uses /dev/tty
1662 by default and uses stderr instead of stdout. A GetPassWarning is
1663 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001678- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001679 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001699- Issue #2550: The approach used by client/server code for obtaining
1700 ports to listen on in network-oriented tests has been refined in an
1701 effort to facilitate running multiple instances of the entire
1702 regression test suite in parallel without issue.
1703 test_support.bind_port() has been fixed such that it will always
1704 return a unique port -- which wasn't always the case with the
1705 previous implementation, especially if socket options had been set
1706 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1707 new implementation of bind_port() will actually raise an exception
1708 if it is passed an AF_INET/SOCK_STREAM socket with either the
1709 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1710 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1711 the socket it's been passed. This currently only applies to
1712 Windows. This option prevents any other sockets from binding to the
1713 host/port we've bound to, thus removing the possibility of the
1714 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1715 when a second SOCK_STREAM socket binds and accepts to a host/port
1716 that's already been bound by another socket. The optional preferred
1717 port parameter to bind_port() has been removed. Under no
1718 circumstances should tests be hard coding ports!
1719
1720 test_support.find_unused_port() has also been introduced, which will
1721 pass a temporary socket object to bind_port() in order to obtain an
1722 unused port. The temporary socket object is then closed and
1723 deleted, and the port is returned. This method should only be used
1724 for obtaining an unused port in order to pass to an external program
1725 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1726 a parameter to a server-oriented class that doesn't give you direct
1727 access to the underlying socket used.
1728
1729 Finally, test_support.HOST has been introduced, which should be used
1730 for the host argument of any relevant socket calls (i.e. bind and
1731 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001732
1733 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001734 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001735 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1736 test_asynchat and test_socket_ssl.
1737
Georg Brandl3ee81df2008-05-17 18:14:43 +00001738 It is now possible for multiple instances of the regression test
1739 suite to run in parallel without issue.

2006-----------------
2007
Fred Drakea8ee94b2008-03-01 02:45:07 +00002008- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002009 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002014
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002015- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002016 issue 215555 for a discussion.
2017
Eric Smitha73fbe72008-02-23 03:09:44 +00002018- Added the future_builtins module, which contains hex() and oct().
2019 These are the PEP 3127 version of these functions, designed to be
2020 compatible with the hex() and oct() builtins from Python 3.0. They
2021 differ slightly in their output formats from the existing, unchanged
2022 Python 2.6 builtins. The expected usage of the future_builtins
2023 module is:
2024 from future_builtins import hex, oct
2025
Eric Smith7ef40bf2008-02-20 23:34:22 +00002026- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2027 exponents for exponents with absolute value < 100. Follows C99
2028 standard. This is a change on Windows, which would use 3 digits.
2029 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2030 so that any alterations it does to the resulting string will be
2031 available in stringlib/formatter.h (for float.__format__).
2032
Eric Smith5a3c1352008-02-19 13:21:56 +00002033- Implemented PEP 3101, Advanced String Formatting. This adds a new
2034 builtin format(); a format() method for str and unicode; a
2035 __format__() method to object, str, unicode, int, long, float, and
2036 datetime; the class string.Formatter; and the C API
2037 PyObject_Format().
2038
Georg Brandl3ee81df2008-05-17 18:14:43 +00002039- Fixed several potential crashes, all caused by specially crafted
2040 __del__ methods exploiting objects in temporarily inconsistent
2041 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002042
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002043- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002044 prevent a possible crash: an Abstract Base Class would try to access
2045 a slot on a registered virtual subclass.

2051 in order to allow pymalloc to free more arenas. Python may give back
2052 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002053
Georg Brandl3ee81df2008-05-17 18:14:43 +00002054- Issue #2045: Fix an infinite recursion triggered when printing a
2055 subclass of collections.defaultdict, if its default_factory is set
2056 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002057
Christian Heimesf75dbef2008-02-08 00:11:31 +00002058- Fixed a minor memory leak in dictobject.c. The content of the free
2059 list was not freed on interpreter shutdown.
2060
Georg Brandl3ee81df2008-05-17 18:14:43 +00002061- Limit free list of method and builtin function objects to 256
2062 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002064- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2065 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002066 to compact the internal free lists of pre-allocted ints and floats.
2067
Georg Brandl3ee81df2008-05-17 18:14:43 +00002068- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2069 calls. Python expected the return type int but the fork familie
2070 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002071
Georg Brandl3ee81df2008-05-17 18:14:43 +00002072- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2073 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002074
Georg Brandl3ee81df2008-05-17 18:14:43 +00002075- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2076 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002077
Georg Brandl3ee81df2008-05-17 18:14:43 +00002078- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2079 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002080
Georg Brandl3ee81df2008-05-17 18:14:43 +00002081- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2082 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002083
Georg Brandl3ee81df2008-05-17 18:14:43 +00002084- Patch #1473257: generator objects gain a gi_code attribute. This is
2085 the same object as the func_code attribute of the function that
2086 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002087
Georg Brandl3ee81df2008-05-17 18:14:43 +00002088- Issue #1920: "while 0" statements were completely removed by the
2089 compiler, even in the presence of an "else" clause, which is
2090 supposed to be run when the condition is false. Now the compiler
2091 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002092
Guido van Rossumeead05f2008-01-24 18:21:02 +00002093- A few crashers fixed: weakref_in_del.py (issue #1377858);
2094 loosing_dict_ref.py (issue #1303614, test67.py);
2095 borrowed_ref_[34].py (not in tracker).
2096
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002097- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002098 suppressed while an extension is loaded by calling SetErrorMode in
2099 dynload_win.c. The error is still reported properly.
2100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002102 several extension methods and modules do not work without unicode
2103 support.
2104
Georg Brandl26543b12008-01-21 18:36:51 +00002105- Issue #1882: when compiling code from a string, encoding cookies in the
2106 second line of code were not always recognized correctly.
2107
Georg Brandl14404b62008-01-19 19:27:05 +00002108- Issue #1679: "0x" was taken as a valid integer literal.
2109
Georg Brandl6caad7d2008-01-26 14:19:22 +00002110- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002111 added.
2112
Christian Heimesc94e2b52008-01-14 04:13:37 +00002113- sys.float_info / PyFloat_GetInfo: The floating point information
2114 object was converted from a dict to a specialized structseq object.
2115
Georg Brandl3ee81df2008-05-17 18:14:43 +00002116- Patch #1816: Added sys.flags structseq. It exposes the status of
2117 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002118
Georg Brandl3ee81df2008-05-17 18:14:43 +00002119- Objects/structseq.c: Implemented new structseq representation. The
2120 patch makes structseqs (e.g. the return value of os.stat) more
2121 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002122
Georg Brandl3ee81df2008-05-17 18:14:43 +00002123- Patch #1700288: added a type attribute cache that caches method
2124 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002125
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002126- Bug #1776: __import__() no longer accepts filenames on any platform.
2127 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002128
Georg Brandlaed6c662008-01-07 17:25:53 +00002129- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2130
Georg Brandl3ee81df2008-05-17 18:14:43 +00002131- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2132 envvar and sys.dont_write_bytecode attribute. All these can be set
2133 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002134
Georg Brandl3ee81df2008-05-17 18:14:43 +00002135- Improve some exception messages when Windows fails to load an
2136 extension module. Now we get for example '%1 is not a valid Win32
2137 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002138

2142 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002143
Christian Heimes0a8143f2007-12-18 23:22:54 +00002144- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002145 and INF. float("nan"), float("inf") and float("-inf") now work on
2146 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- Compiler now generates simpler and faster code for dictionary
2149 literals. The oparg for BUILD_MAP now indicates an estimated
2150 dictionary size. There is a new opcode, STORE_MAP, for adding
2151 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002180- Patch #1739468: Directories and zipfiles containing a __main__.py
2181 file can now be directly executed by passing their name to the
2182 interpreter. The directory/zipfile is automatically inserted as the
2183 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002184
Georg Brandl3ee81df2008-05-17 18:14:43 +00002185- Issue #1265: Fix a problem with sys.settrace, if the tracing
2186 function uses a generator expression when at the same time the
2187 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002188
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002189- sets and frozensets now have an isdisjoint() method.
2190

2192
Neal Norwitz44f326e2007-10-05 05:29:17 +00002193- Fix warnings found by the new version of the Coverity checker.
2194
Georg Brandl3ee81df2008-05-17 18:14:43 +00002195- The enumerate() builtin function is no longer bounded to sequences
2196 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2197 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002198
Georg Brandl3ee81df2008-05-17 18:14:43 +00002199- Issue #1686386: Tuple's tp_repr did not take into account the
2200 possibility of having a self-referential tuple, which is possible
2201 from C code. Nor did object's tp_str consider that a type's tp_str
2202 could do something that could lead to an inifinite recursion.
2203 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2204 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002205
Georg Brandl3ee81df2008-05-17 18:14:43 +00002206- Issue #1164: It was possible to trigger deadlock when using the
2207 'print' statement to write to a file since the GIL was not released
2208 as needed. Now PyObject_Print() does the right thing along with
2209 various tp_print implementations of the built-in types and those in
2210 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002211
Georg Brandl3ee81df2008-05-17 18:14:43 +00002212- Issue #1147: Exceptions were directly allowing string exceptions in
2213 their throw() method even though string exceptions no longer
2214 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002215
Georg Brandl3ee81df2008-05-17 18:14:43 +00002216- Issue #1096: Prevent a segfault from getting the repr of a very
2217 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002218
Brett Cannon1e534b52007-09-07 04:18:30 +00002219- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002220 PyObject_Call() never calling back out to Python code to trigger
2221 recursion depth updates/checks. Required the creation of a static
2222 RuntimeError instance in case normalizing an exception put the
2223 recursion check value past its limit. Fixes crashers
2224 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002225
Georg Brandl3ee81df2008-05-17 18:14:43 +00002226- Patch #1031213: Decode source line in SyntaxErrors back to its

2230 with %G.
2231
Georg Brandl3ee81df2008-05-17 18:14:43 +00002232- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002239- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002240 __*__ attributes. (Some already existed, e.g., __doc__ and
2241 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002242
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002243- Add -3 option to the interpreter to warn about features that are
2244 deprecated and will be changed/removed in Python 3.0.
2245
Georg Brandl2134e752007-05-21 20:34:16 +00002246- Patch #1686487: you can now pass any mapping after '**' in function
2247 calls.
2248
Collin Winter62903052007-05-18 23:11:24 +00002249- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002250 "except E as target:". This is to provide forwards compatibility
2251 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002252
Brett Cannon229cee22007-05-05 01:34:02 +00002253- Deprecate BaseException.message as per PEP 352.
2254
Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002256 inherited from a builtin base.
2257
Vinay Sajip8549ce32007-05-06 17:53:37 +00002258- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002259 setting a plain string, ie don't expand to single letter identifiers.
2260
Raymond Hettinger13936692007-04-11 18:40:58 +00002261- Request #1191699: Slices can now be pickled.
2262
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002263- Request #1193128: str.translate() now allows a None argument for
2264 translations that only remove characters without re-mapping the
2265 remaining characters.
2266
Georg Brandl5cb76c12007-03-21 09:00:39 +00002267- Patch #1682205: a TypeError while unpacking an iterable is no longer
2268 masked by a generic one with the message "unpack non-sequence".
2269
Neal Norwitzaa754b72007-03-21 06:39:48 +00002270- Remove unused file Python/fmod.c.
2271
Guido van Rossum143b5642007-03-23 04:58:42 +00002272- Bug #1683368: The object.__init__() and object.__new__() methods are
2273 now stricter in rejecting excess arguments. The only time when
2274 either allows excess arguments is when it is not overridden and the
2275 other one is. For backwards compatibility, when both are
2276 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002277 warning later). Also, type.__init__() insists on the same signature
2278 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002279
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2281 object to complex using its __complex__() method before falling back
2282 to the __float__() method. Therefore, the functions in the cmath
2283 module now can operate on objects that define a __complex__()
2284 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002285
Georg Brandl3ee81df2008-05-17 18:14:43 +00002286- Patch #1623563: allow __class__ assignment for classes with
2287 __slots__. The old and the new class are still required to have the
2288 same slot names.

2294 ``object.__reduce_ex__()`` is called with an object that is faking
2295 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002296
Georg Brandl3ee81df2008-05-17 18:14:43 +00002297- Patch #1680015: Don't modify __slots__ tuple if it contains an

2301
Georg Brandl7b9c5552007-03-12 14:30:05 +00002302- Bug #1678647: write a newline after printing an exception in any
2303 case, even when converting the value to a string failed.
2304
Georg Brandl871f1bc2007-03-12 13:17:36 +00002305- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002306 its argument, if it exists. If not, it will work like before. This
2307 allows customizing the output of dir() in the presence of a
2308 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00002310- Patch #922167: Python no longer segfaults when faced with infinitely
2311 self-recursive reload() calls (as reported by bug #742342).
2312

Georg Brandl4e933132006-09-06 20:05:58 +00002423- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002441 generator expressions (x for x, in ... ) works again. Fixing this
2442 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00002482- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00002832 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003358 time so that opening a database previously created with the DB_DUP
3359 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3360 opens. Specifically: dictionary assignment to a DB object will
3361 replace all values for a given key when the database allows
3362 duplicate values. DB users should use DB.put(k, v) when they want
3363 to store duplicates; not DB[k] = v.

3370 characters with ASCII value less than 32. Also, it correctly quotes
3371 dots only if they occur on a single line, as opposed to the previous
3372 behavior of quoting dots if they are the second character of any
3373 line.
