370 traditional 2.x file object.

566What's New in Python 2.6.1
567==========================
568
569*Release date: 04-Dec-2008*
570
571Core and Builtins
572-----------------
573
574- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
575 interpreter to abort ("Fatal Python error: Could not reset the stack!")
576 instead of throwing a MemoryError.
577
578- Issue #4367: Python would segfault during compiling when the unicodedata
579 module couldn't be imported and \N escapes were present.
580
581- Issue #4348: Some bytearray methods returned that didn't cause any change to
582 the bytearray, returned the same bytearray instead of a copy.
583
584- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
585
586- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
587
588- Issue #4048: The parser module now correctly validates relative imports.
589
590- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
591 exec statement.
592
593- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
594 method does not return iterators for the 4th and 5th items.
595
596- Issue #4209: Enabling unicode_literals and the print_function in the same
597 __future__ import didn't work.
598
599- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
600 returned a path longer than MAX_PATH. (But It's doubtful this code path is
601 really executed because I cannot move to such directory on win2k)
602
603- Issue #4069: When set.remove(element) is used with a set element, the element
604 is temporarily replaced with an equivalent frozenset. But the eventual
605 KeyError would always report the empty frozenset([]) as the missing key. Now
606 it correctly refers to the initial element.
607
608- Fixed C99 style comments in several files. Python is now C89 compatible
609 again.

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

755
Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000756- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
757
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000758- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
759 PyString_FromFormat or PyErr_Format to display size_t values. The macro
760 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
761 ``printf`` function, whereas PyString_FromFormat has an independent
762 implementation and uses "%zd" on all platforms for size_t values.
763 This makes a difference on win64, where ``printf`` needs "%Id" to display
764 64bit values.
765
Benjamin Peterson97179b02008-09-09 20:55:01 +0000766- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
767 error.
768
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000769- Issue #3777: long() applied to a float object now always return a long
770 object; previously an int would be returned for small values. the __long__
771 method is allowed to return either an int or a long, but the behaviour of
772 float objects should not change to respect backward compatibility.
773
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000774- Issue #3751: str.rpartition would perform a left-partition when called with
775 a unicode argument.
776
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000777- Issue #3683: Fix compilation when --without-threads is given.
778
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000779- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000780 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000781 was correctly parsed but parsing of subsequent arguments failed.
782
Vinay Sajip35e3b032008-09-01 14:33:59 +0000783- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000784 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
785 mechanism. In the process, fix a bug where isinstance() and issubclass(),
786 when given a tuple of classes as second argument, were looking up
787 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
788 type object.
789
Neal Norwitz18aa3882008-08-24 05:04:52 +0000790- Fix crashes on memory allocation failure found with failmalloc.
791
792- Fix memory leaks found with valgrind and update suppressions file.
793
794- Fix compiler warnings in opt mode which would lead to invalid memory reads.
795
796- Fix problem using wrong name in decimal module reported by pychecker.
797
Christian Heimes7d4c3172008-08-22 19:47:25 +0000798- Silenced another compiler warning about a used but not defined
799 function 'stringlib_contains_obj'.

802 ``__delslice__``.
803
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +0000804- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
805 library targets in the Makefile.
806
Gregory P. Smith980b99b2008-09-07 05:15:18 +0000807- Issue #1204: The configure script now tests for additional libraries
808 that may be required when linking against readline. This fixes issues
809 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +0000826- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
827 silent misbehaviour when a single instance is nested in multiple
828 with statements, or when the methods are invoked in the wrong order.
829
Vinay Sajip844f7412008-09-09 13:42:08 +0000830- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

859 warnings.catch_warnings() along with some API cleanup. Expanding the tests
860 for catch_warnings() also led to an improvement in the raising of a
861 DeprecationWarning related to warnings.warn_explicit().
862
Benjamin Peterson973e6c22008-09-01 23:12:58 +0000863- The deprecation warnings for the old camelCase threading API were removed.

929Core and Builtins
930-----------------
931
Guido van Rossumf8402962008-08-20 15:01:50 +0000932- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
933 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
934 extensions do not automatically benefit from the class attribute
935 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
936 to their tp_flags field if they care. This is a backwards
937 compatibility feature; in 3.0, all types will use the cache by
938 default.
939
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000940- Keyword arguments can now follow starred arguments. (``f(a, *args,
941 keyword=23)`` is now valid syntax.)
942
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000943- ctypes function pointers that are COM methods have a boolean True
944 value again.
945
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000946- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
947 by denying s# to parse objects that have a releasebuffer procedure,
948 and introducing s*.
949
Georg Brandl1e13ea92008-08-11 09:07:59 +0000950- Issue #3537: Fix an assertion failure when an empty but presized dict
951 object was stored in the freelist.
952
Mark Dickinsonb6467572008-08-04 21:30:09 +0000953- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
954 ValueError consistently across platforms.
955
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000956- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
957 (64bit Unix, for example), unichr() would truncate its argument and return
958 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
959
Neal Norwitze7d8be82008-07-31 17:17:14 +0000960- Apply security patches from Apple.
961
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000962- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
963 PyErr_ExceptionMatches returns 0 when an exception occurs there.
964
Antoine Pitrou92f82162008-07-25 22:22:08 +0000965- Issue #1819: function calls with several named parameters are now on
966 average 35% faster (as measured by pybench).
967
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000968- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
969 the python debugger steps into a class statement: the free variables (local
970 variables defined in an outer scope) would be deleted from the outer scope.
971
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000972- Issue #2620: Overflow checking when allocating or reallocating memory
973 was not always being done properly in some python types and extension
974 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
975 all been updated to perform better checks and places in the code that
976 would previously leak memory on the error path when such an allocation
977 failed have been fixed.

Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000987- Issue #2234: distutils failed for some versions of the cygwin compiler. The
988 version reported by these tools does not necessarily follow the python
989 version numbering scheme, so the module is less strict when parsing it.
990
Nick Coghlanf70385a2008-08-18 12:42:46 +0000991- Issue #2235: Added Py3k warnings for types which will become unhashable
992 under the stricter __hash__ inheritance rules in 3.0. Several types
993 which did not meet the rules for hash invariants and were already
994 unhashable in 3.0 have now been explicitly flagged as unhashable in
995 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
996 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
997
Brett Cannon88f801d2008-08-18 00:46:22 +0000998- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1021
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001022- Issue #2676: in the email package, content-type parsing was hanging on

1024 regular expression.
1025
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001026- Issue #3476: binary buffered reading through the new "io" library is now
1027 thread-safe.
1028
Brett Cannonbf3157b2008-08-14 05:00:03 +00001029- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1030 since mimetools itself is deprecated. Because modules are cached, all
1031 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1032
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001033- Issue #3134: shutil referenced undefined WindowsError symbol.

1039 version that did not raise a DeprecationWarning under -3.
1040
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001041- Issue #3205: When iterating over a BZ2File fails allocating memory, raise

1045 to _sre.compile() will now be rejected. This should not affect anybody
1046 since the re.compile() function never generates invalid re-bytecode.
1047
Skip Montanaroa032bf42008-08-08 22:52:51 +00001048- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1049 upon first access it can be automatically initialized from the csv file if
1050 it wasn't initialized during instantiation.
1051
Brett Cannon3aa2a492008-08-06 22:28:09 +00001052- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1053 the reload() built-in has been removed.
1054
Brett Cannon7e30b672008-08-04 21:52:25 +00001055- Changed code in the following modules/packages to remove warnings raised

1064 raised an AttributeError.
1065
Benjamin Peterson01a24322008-07-28 23:35:27 +00001066- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001067 asking for a specific length. This problem only affected files opened
1068 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001069

1094 file name rather than a ZipInfo instance, so files are extracted with
1095 mode 0600 rather than 000 under Unix.
1096
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001097- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001109- Issue #2235: the C API function PyObject_HashNotImplemented and its
1110 interaction with the tp_hash slot (added in 2.6b2) are now documented
1111
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001112- Issue #643841: The language reference now provides more detailed
1113 coverage of the lookup process for special methods. The disclaimers
1114 regarding lack of coverage of new-style classes have also been
1115 removed, since the coverage is now fairly reasonable.

1119================================
1120
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001121*Release date: 17-Jul-2008*
1122
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001123Core and Builtins
1124-----------------
1125
Georg Brandl3e483f62008-07-16 22:57:41 +00001126- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1127 its methods now allow for items objects that can be converted to
1128 an integer using operator.index().
1129
Mark Dickinson64b7e502008-07-16 09:40:03 +00001130- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1131 produced a ValueError instead of giving the correct float.
1132
Eric Smitha5fa5a22008-07-16 00:11:49 +00001133- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1134 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1135
Mark Dickinson7103aa42008-07-15 19:08:33 +00001136- Issue #3008: the float type has a new instance method 'float.hex'
1137 and a new class method 'float.fromhex' to convert floating-point
1138 numbers to and from hexadecimal strings, respectively.
1139
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001140- Issue #2235: __hash__ is once again inherited by default. To allow
1141 collections.Hashable to remain meaningful in the presence of the
1142 default hash implementation (object.__hash__), it is now possible
1143 to explicit block inheritance of hash by setting __hash__=None at
1144 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1145 level.
1146
Nick Coghlanb028f502008-07-13 14:52:36 +00001147- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1148 the parent module cannot be found while performing an absolute import.
1149 This means that an incorrectly defined __package__ attribute will
1150 now only prevent relative imports in that module rather than causing
1151 all imports from that module to fail.
1152
Nick Coghlan14ff9942008-07-08 14:21:42 +00001153- Issue #2517: Allow unicode messages in Exceptions again by correctly
1154 bypassing the instance dictionary when looking up __unicode__ on
1155 new-style classes.
1156
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001157- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1158 set to a custom object whose write() method happens to install
1159 another file in sys.stdout.
1160
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001161- Issue #3088: Corrected a race condition in classes derived from
1162 threading.local: the first member set by a thread could be saved in
1163 another thread's dictionary.
1164
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001165- Issue #3004: Minor change to slice.indices(): the start and stop
1166 arguments are now treated identically, making the behaviour easier
1167 to describe and understand. For example, slice(None, -10,
1168 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1169 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1170 10, -1).
1171
Georg Brandl278fc502008-07-19 12:46:12 +00001172- Issue #3219: Calling a function with repeated keyword arguments,
1173 f(a=2, a=23), would not cause a syntax error. This was a regression
1174 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001175
Georg Brandl278fc502008-07-19 12:46:12 +00001176- Issue #2862: Make int and float freelist management consistent with
1177 other freelists. Changes their CompactFreeList apis into
1178 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001179

1181-------
1182
Thomas Heller57adf222008-08-14 19:10:48 +00001183- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1184 api functions without holding the GIL, which could lead to a fatal
1185 error when they failed.
1186
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001187- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1196 ForkingPickler.register() to resolve conflict with ctypes.
1197
Vinay Sajip51e65192008-07-18 09:01:10 +00001198- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00001200- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1201 a valid dlerror() message.
1202
Thomas Heller2bad6572008-07-15 17:19:50 +00001203- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1204 incomplete structure was created.
1205

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001210- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001211
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001212- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1213 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001214 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001215 content-length. The problem had been corrected in the 2.4 branch, but never
1216 merged into trunk.
1217
Georg Brandle78fbcc2008-07-05 10:13:36 +00001218- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001231- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1232 handling is now the same as that of other special attributes like __name__).
1233
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001234- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00001622- On MacOS X it is now possible to install the framework in 64-bit
1623 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001624 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001625
1626 This is controlled by the configure argument ``--with-universal-archs``:
1627
1628 - ``--with-universal-archs=all``: install 4-way universal
1629
1630 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1631
1632 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1633
1634 This option should be used in combination with ``--enable-universalsdk=``.
1635
1636 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 +00001686- Issue #1631171: Re-implement the 'warnings' module in C (the
1687 original Python code has been kept as backup). This will allow for
1688 using the 'warning's machinery in such places as the parser where
1689 use of pure Python code is not possible. Both the ``showarning()``
1690 and ``formatwarning()`` gain an optional 'line' argument which is
1691 not called by default for backwards-compatibility reasons. Setting
1692 ``warnings.showwarning()`` to an implementation that lacks support
1693 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001756- Issue #2550: The approach used by client/server code for obtaining
1757 ports to listen on in network-oriented tests has been refined in an
1758 effort to facilitate running multiple instances of the entire
1759 regression test suite in parallel without issue.
1760 test_support.bind_port() has been fixed such that it will always
1761 return a unique port -- which wasn't always the case with the
1762 previous implementation, especially if socket options had been set
1763 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1764 new implementation of bind_port() will actually raise an exception
1765 if it is passed an AF_INET/SOCK_STREAM socket with either the
1766 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1767 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1768 the socket it's been passed. This currently only applies to
1769 Windows. This option prevents any other sockets from binding to the
1770 host/port we've bound to, thus removing the possibility of the
1771 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1772 when a second SOCK_STREAM socket binds and accepts to a host/port
1773 that's already been bound by another socket. The optional preferred
1774 port parameter to bind_port() has been removed. Under no
1775 circumstances should tests be hard coding ports!
1776
1777 test_support.find_unused_port() has also been introduced, which will
1778 pass a temporary socket object to bind_port() in order to obtain an
1779 unused port. The temporary socket object is then closed and
1780 deleted, and the port is returned. This method should only be used
1781 for obtaining an unused port in order to pass to an external program
1782 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1783 a parameter to a server-oriented class that doesn't give you direct
1784 access to the underlying socket used.
1785
1786 Finally, test_support.HOST has been introduced, which should be used
1787 for the host argument of any relevant socket calls (i.e. bind and
1788 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001789
1790 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001791 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001792 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1793 test_asynchat and test_socket_ssl.
1794
Georg Brandl3ee81df2008-05-17 18:14:43 +00001795 It is now possible for multiple instances of the regression test
1796 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00001850- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00001851 \Uxxxxxxxx did not accept values outside the Basic Multilingual
1852 Plane. This affected raw unicode literals and the
1853 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
1854 this case, like normal unicode literals and the 'unicode-escape'
1855 codec.

2074
Eric Smitha73fbe72008-02-23 03:09:44 +00002075- Added the future_builtins module, which contains hex() and oct().
2076 These are the PEP 3127 version of these functions, designed to be
2077 compatible with the hex() and oct() builtins from Python 3.0. They
2078 differ slightly in their output formats from the existing, unchanged
2079 Python 2.6 builtins. The expected usage of the future_builtins
2080 module is:

2082
Eric Smith7ef40bf2008-02-20 23:34:22 +00002083- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2084 exponents for exponents with absolute value < 100. Follows C99
2085 standard. This is a change on Windows, which would use 3 digits.
2086 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2087 so that any alterations it does to the resulting string will be
2088 available in stringlib/formatter.h (for float.__format__).
2089
Eric Smith5a3c1352008-02-19 13:21:56 +00002090- Implemented PEP 3101, Advanced String Formatting. This adds a new
2091 builtin format(); a format() method for str and unicode; a
2092 __format__() method to object, str, unicode, int, long, float, and
2093 datetime; the class string.Formatter; and the C API
2094 PyObject_Format().
2095
Georg Brandl3ee81df2008-05-17 18:14:43 +00002096- Fixed several potential crashes, all caused by specially crafted
2097 __del__ methods exploiting objects in temporarily inconsistent
2098 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002099
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002100- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101 prevent a possible crash: an Abstract Base Class would try to access
2102 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002103

Georg Brandl3ee81df2008-05-17 18:14:43 +00002107- Clear all free lists during a gc.collect() of the highest generation
2108 in order to allow pymalloc to free more arenas. Python may give back
2109 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002110
Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Issue #2045: Fix an infinite recursion triggered when printing a
2112 subclass of collections.defaultdict, if its default_factory is set
2113 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00002115- Fixed a minor memory leak in dictobject.c. The content of the free
2116 list was not freed on interpreter shutdown.
2117
Georg Brandl3ee81df2008-05-17 18:14:43 +00002118- Limit free list of method and builtin function objects to 256
2119 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002120
Georg Brandl3ee81df2008-05-17 18:14:43 +00002121- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2122 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002123 to compact the internal free lists of pre-allocted ints and floats.
2124
Georg Brandl3ee81df2008-05-17 18:14:43 +00002125- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2126 calls. Python expected the return type int but the fork familie
2127 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002128
Georg Brandl3ee81df2008-05-17 18:14:43 +00002129- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2130 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002141- Patch #1473257: generator objects gain a gi_code attribute. This is
2142 the same object as the func_code attribute of the function that
2143 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002144
Georg Brandl3ee81df2008-05-17 18:14:43 +00002145- Issue #1920: "while 0" statements were completely removed by the
2146 compiler, even in the presence of an "else" clause, which is
2147 supposed to be run when the condition is false. Now the compiler
2148 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002149
Guido van Rossumeead05f2008-01-24 18:21:02 +00002150- A few crashers fixed: weakref_in_del.py (issue #1377858);
2151 loosing_dict_ref.py (issue #1303614, test67.py);
2152 borrowed_ref_[34].py (not in tracker).
2153
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002154- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002155 suppressed while an extension is loaded by calling SetErrorMode in
2156 dynload_win.c. The error is still reported properly.
2157
Georg Brandl3ee81df2008-05-17 18:14:43 +00002158- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002159 several extension methods and modules do not work without unicode
2160 support.
2161
Georg Brandl26543b12008-01-21 18:36:51 +00002162- Issue #1882: when compiling code from a string, encoding cookies in the
2163 second line of code were not always recognized correctly.
2164
Georg Brandl14404b62008-01-19 19:27:05 +00002165- Issue #1679: "0x" was taken as a valid integer literal.
2166
Georg Brandl6caad7d2008-01-26 14:19:22 +00002167- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002168 added.
2169
Christian Heimesc94e2b52008-01-14 04:13:37 +00002170- sys.float_info / PyFloat_GetInfo: The floating point information
2171 object was converted from a dict to a specialized structseq object.
2172
Georg Brandl3ee81df2008-05-17 18:14:43 +00002173- Patch #1816: Added sys.flags structseq. It exposes the status of
2174 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002175
Georg Brandl3ee81df2008-05-17 18:14:43 +00002176- Objects/structseq.c: Implemented new structseq representation. The
2177 patch makes structseqs (e.g. the return value of os.stat) more
2178 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002179
Georg Brandl3ee81df2008-05-17 18:14:43 +00002180- Patch #1700288: added a type attribute cache that caches method
2181 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002182
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002183- Bug #1776: __import__() no longer accepts filenames on any platform.
2184 The first parameter to __import__() must be a valid module name.

2189 envvar and sys.dont_write_bytecode attribute. All these can be set
2190 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002191
Georg Brandl3ee81df2008-05-17 18:14:43 +00002192- Improve some exception messages when Windows fails to load an
2193 extension module. Now we get for example '%1 is not a valid Win32
2194 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002195

2251
Georg Brandl3ee81df2008-05-17 18:14:43 +00002252- The enumerate() builtin function is no longer bounded to sequences
2253 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2254 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002255
Georg Brandl3ee81df2008-05-17 18:14:43 +00002256- Issue #1686386: Tuple's tp_repr did not take into account the
2257 possibility of having a self-referential tuple, which is possible
2258 from C code. Nor did object's tp_str consider that a type's tp_str
2259 could do something that could lead to an inifinite recursion.
2260 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2261 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002262
Georg Brandl3ee81df2008-05-17 18:14:43 +00002263- Issue #1164: It was possible to trigger deadlock when using the
2264 'print' statement to write to a file since the GIL was not released
2265 as needed. Now PyObject_Print() does the right thing along with
2266 various tp_print implementations of the built-in types and those in
2267 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002268
Georg Brandl3ee81df2008-05-17 18:14:43 +00002269- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002277 PyObject_Call() never calling back out to Python code to trigger
2278 recursion depth updates/checks. Required the creation of a static
2279 RuntimeError instance in case normalizing an exception put the
2280 recursion check value past its limit. Fixes crashers
2281 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002282

2304 calls.
2305
Collin Winter62903052007-05-18 23:11:24 +00002306- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002307 "except E as target:". This is to provide forwards compatibility
2308 with Python 3.0.

2328
Guido van Rossum143b5642007-03-23 04:58:42 +00002329- Bug #1683368: The object.__init__() and object.__new__() methods are
2330 now stricter in rejecting excess arguments. The only time when
2331 either allows excess arguments is when it is not overridden and the
2332 other one is. For backwards compatibility, when both are
2333 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002334 warning later). Also, type.__init__() insists on the same signature
2335 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002337- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2338 object to complex using its __complex__() method before falling back
2339 to the __float__() method. Therefore, the functions in the cmath
2340 module now can operate on objects that define a __complex__()
2341 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00002359- Bug #1678647: write a newline after printing an exception in any
2360 case, even when converting the value to a string failed.
2361
Georg Brandl871f1bc2007-03-12 13:17:36 +00002362- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002363 its argument, if it exists. If not, it will work like before. This
2364 allows customizing the output of dir() in the presence of a
2365 __getattr__().

2375 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002376
Georg Brandlaa2321b2007-03-07 00:40:28 +00002377- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002378 makes the filenames the warning module prints much more sensible
2379 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002392- Patch #1674228: when assigning a slice (old-style), check for the
2393 sq_ass_slice instead of the sq_slice slot.
2394
Georg Brandl3ee81df2008-05-17 18:14:43 +00002395- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00002447- Bug #1545497: when given an explicit base, int() did ignore NULs
2448 embedded in the string to convert.
2449
Georg Brandl846f73a2006-10-08 07:11:54 +00002450- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002498 generator expressions (x for x, in ... ) works again. Fixing this
2499 problem required changing the .pyc magic number. This means that
2500 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002930 AttributeError instead of an IOError when the server's response

3022 TestCase and TestSuite subclasses (not instances) are no longer

3025 -- the failure just occurred later, with a more cumbersome
3026 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003303- The implementation of UnicodeError objects has been simplified
3304 (start and end attributes are now stored directly as Py_ssize_t
3305 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3308 with RFC 3207 and forgets any knowledge obtained from the server not
3309 obtained from the TLS negotiation itself. Patch contributed by Bill
3310 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003311
Georg Brandl3ee81df2008-05-17 18:14:43 +00003312- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003313 that the SMTP.starttls() caller no longer needs to call ehlo()
3314 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003315 does not claim to support starttls. Adds the
3316 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3317 Fenner.

3397 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3398 silently miscode subclasses of those types. Now, it raises a
3399 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003400

Georg Brandl3ee81df2008-05-17 18:14:43 +00003415 time so that opening a database previously created with the DB_DUP
3416 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3417 opens. Specifically: dictionary assignment to a DB object will
3418 replace all values for a given key when the database allows
3419 duplicate values. DB users should use DB.put(k, v) when they want
3420 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003421

3427 characters with ASCII value less than 32. Also, it correctly quotes
3428 dots only if they occur on a single line, as opposed to the previous
3429 behavior of quoting dots if they are the second character of any
3430 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003431
