548What's New in Python 2.6.1
549==========================
550
551*Release date: 04-Dec-2008*
552
553Core and Builtins
554-----------------
555
556- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
557 interpreter to abort ("Fatal Python error: Could not reset the stack!")
558 instead of throwing a MemoryError.
559
560- Issue #4367: Python would segfault during compiling when the unicodedata
561 module couldn't be imported and \N escapes were present.
562
563- Issue #4348: Some bytearray methods returned that didn't cause any change to
564 the bytearray, returned the same bytearray instead of a copy.
565
566- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
567
568- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
569
570- Issue #4048: The parser module now correctly validates relative imports.
571
572- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
573 exec statement.
574
575- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
576 method does not return iterators for the 4th and 5th items.
577
578- Issue #4209: Enabling unicode_literals and the print_function in the same
579 __future__ import didn't work.
580
581- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
582 returned a path longer than MAX_PATH. (But It's doubtful this code path is
583 really executed because I cannot move to such directory on win2k)
584
585- Issue #4069: When set.remove(element) is used with a set element, the element
586 is temporarily replaced with an equivalent frozenset. But the eventual
587 KeyError would always report the empty frozenset([]) as the missing key. Now
588 it correctly refers to the initial element.
589
590- Fixed C99 style comments in several files. Python is now C89 compatible
591 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000738- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
739
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000740- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
741 PyString_FromFormat or PyErr_Format to display size_t values. The macro
742 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
743 ``printf`` function, whereas PyString_FromFormat has an independent
744 implementation and uses "%zd" on all platforms for size_t values.
745 This makes a difference on win64, where ``printf`` needs "%Id" to display
746 64bit values.
747
Benjamin Peterson97179b02008-09-09 20:55:01 +0000748- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
749 error.
750
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000751- Issue #3777: long() applied to a float object now always return a long
752 object; previously an int would be returned for small values. the __long__
753 method is allowed to return either an int or a long, but the behaviour of
754 float objects should not change to respect backward compatibility.
755
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000756- Issue #3751: str.rpartition would perform a left-partition when called with
757 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000762 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000763 was correctly parsed but parsing of subsequent arguments failed.
764
Vinay Sajip35e3b032008-09-01 14:33:59 +0000765- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000766 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
767 mechanism. In the process, fix a bug where isinstance() and issubclass(),
768 when given a tuple of classes as second argument, were looking up
769 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
770 type object.

841 warnings.catch_warnings() along with some API cleanup. Expanding the tests
842 for catch_warnings() also led to an improvement in the raising of a
843 DeprecationWarning related to warnings.warn_explicit().

911Core and Builtins
912-----------------
913
Guido van Rossumf8402962008-08-20 15:01:50 +0000914- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
915 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
916 extensions do not automatically benefit from the class attribute
917 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
918 to their tp_flags field if they care. This is a backwards
919 compatibility feature; in 3.0, all types will use the cache by
920 default.
921
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000922- Keyword arguments can now follow starred arguments. (``f(a, *args,
923 keyword=23)`` is now valid syntax.)
924
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000925- ctypes function pointers that are COM methods have a boolean True
926 value again.
927
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000928- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
929 by denying s# to parse objects that have a releasebuffer procedure,
930 and introducing s*.
931
Georg Brandl1e13ea92008-08-11 09:07:59 +0000932- Issue #3537: Fix an assertion failure when an empty but presized dict
933 object was stored in the freelist.
934
Mark Dickinsonb6467572008-08-04 21:30:09 +0000935- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
936 ValueError consistently across platforms.
937
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000938- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
939 (64bit Unix, for example), unichr() would truncate its argument and return
940 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
941
Neal Norwitze7d8be82008-07-31 17:17:14 +0000942- Apply security patches from Apple.
943
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000944- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
945 PyErr_ExceptionMatches returns 0 when an exception occurs there.
946
Antoine Pitrou92f82162008-07-25 22:22:08 +0000947- Issue #1819: function calls with several named parameters are now on
948 average 35% faster (as measured by pybench).
949
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000950- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
951 the python debugger steps into a class statement: the free variables (local
952 variables defined in an outer scope) would be deleted from the outer scope.
953
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000954- Issue #2620: Overflow checking when allocating or reallocating memory
955 was not always being done properly in some python types and extension
956 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
957 all been updated to perform better checks and places in the code that
958 would previously leak memory on the error path when such an allocation
959 failed have been fixed.

965
Benjamin Petersone977ad42008-08-20 01:42:01 +0000966- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
967 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
968
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000969- Issue #2234: distutils failed for some versions of the cygwin compiler. The
970 version reported by these tools does not necessarily follow the python
971 version numbering scheme, so the module is less strict when parsing it.
972
Nick Coghlanf70385a2008-08-18 12:42:46 +0000973- Issue #2235: Added Py3k warnings for types which will become unhashable
974 under the stricter __hash__ inheritance rules in 3.0. Several types
975 which did not meet the rules for hash invariants and were already
976 unhashable in 3.0 have now been explicitly flagged as unhashable in
977 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
978 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
979
Brett Cannon88f801d2008-08-18 00:46:22 +0000980- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
981 imported into the module but exposed as part of the module's API.
982

1093
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001094- Issue #643841: The language reference now provides more detailed

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001105Core and Builtins
1106-----------------
1107
Georg Brandl3e483f62008-07-16 22:57:41 +00001108- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1109 its methods now allow for items objects that can be converted to
1110 an integer using operator.index().
1111
Mark Dickinson64b7e502008-07-16 09:40:03 +00001112- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1113 produced a ValueError instead of giving the correct float.
1114
Eric Smitha5fa5a22008-07-16 00:11:49 +00001115- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1116 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1117
Mark Dickinson7103aa42008-07-15 19:08:33 +00001118- Issue #3008: the float type has a new instance method 'float.hex'
1119 and a new class method 'float.fromhex' to convert floating-point
1120 numbers to and from hexadecimal strings, respectively.
1121
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001122- Issue #2235: __hash__ is once again inherited by default. To allow
1123 collections.Hashable to remain meaningful in the presence of the
1124 default hash implementation (object.__hash__), it is now possible
1125 to explicit block inheritance of hash by setting __hash__=None at
1126 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1127 level.
1128
Nick Coghlanb028f502008-07-13 14:52:36 +00001129- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1130 the parent module cannot be found while performing an absolute import.
1131 This means that an incorrectly defined __package__ attribute will
1132 now only prevent relative imports in that module rather than causing
1133 all imports from that module to fail.
1134
Nick Coghlan14ff9942008-07-08 14:21:42 +00001135- Issue #2517: Allow unicode messages in Exceptions again by correctly
1136 bypassing the instance dictionary when looking up __unicode__ on
1137 new-style classes.

1140 set to a custom object whose write() method happens to install
1141 another file in sys.stdout.

1145 another thread's dictionary.
1146
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001147- Issue #3004: Minor change to slice.indices(): the start and stop
1148 arguments are now treated identically, making the behaviour easier
1149 to describe and understand. For example, slice(None, -10,
1150 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1151 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1152 10, -1).
1153
Georg Brandl278fc502008-07-19 12:46:12 +00001154- Issue #3219: Calling a function with repeated keyword arguments,
1155 f(a=2, a=23), would not cause a syntax error. This was a regression
1156 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001157
Georg Brandl278fc502008-07-19 12:46:12 +00001158- Issue #2862: Make int and float freelist management consistent with
1159 other freelists. Changes their CompactFreeList apis into

1167 error when they failed.
1168
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001169- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001194- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1195 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001196 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001197 content-length. The problem had been corrected in the 2.4 branch, but never
1198 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001213- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1556 large to fit in a C long. ldexp(x, n) now returns a zero (with
1557 suitable sign) if n is large and negative; previously, it raised

1603
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001604- On MacOS X it is now possible to install the framework in 64-bit
1605 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001606 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001607
1608 This is controlled by the configure argument ``--with-universal-archs``:
1609
1610 - ``--with-universal-archs=all``: install 4-way universal
1611
1612 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1613
1614 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1615
1616 This option should be used in combination with ``--enable-universalsdk=``.
1617
1618 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 +00001668- Issue #1631171: Re-implement the 'warnings' module in C (the
1669 original Python code has been kept as backup). This will allow for
1670 using the 'warning's machinery in such places as the parser where
1671 use of pure Python code is not possible. Both the ``showarning()``
1672 and ``formatwarning()`` gain an optional 'line' argument which is
1673 not called by default for backwards-compatibility reasons. Setting
1674 ``warnings.showwarning()`` to an implementation that lacks support
1675 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001738- Issue #2550: The approach used by client/server code for obtaining
1739 ports to listen on in network-oriented tests has been refined in an
1740 effort to facilitate running multiple instances of the entire
1741 regression test suite in parallel without issue.
1742 test_support.bind_port() has been fixed such that it will always
1743 return a unique port -- which wasn't always the case with the
1744 previous implementation, especially if socket options had been set
1745 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1746 new implementation of bind_port() will actually raise an exception
1747 if it is passed an AF_INET/SOCK_STREAM socket with either the
1748 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1749 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1750 the socket it's been passed. This currently only applies to
1751 Windows. This option prevents any other sockets from binding to the
1752 host/port we've bound to, thus removing the possibility of the
1753 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1754 when a second SOCK_STREAM socket binds and accepts to a host/port
1755 that's already been bound by another socket. The optional preferred
1756 port parameter to bind_port() has been removed. Under no
1757 circumstances should tests be hard coding ports!
1758
1759 test_support.find_unused_port() has also been introduced, which will
1760 pass a temporary socket object to bind_port() in order to obtain an
1761 unused port. The temporary socket object is then closed and
1762 deleted, and the port is returned. This method should only be used
1763 for obtaining an unused port in order to pass to an external program
1764 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1765 a parameter to a server-oriented class that doesn't give you direct
1766 access to the underlying socket used.
1767
1768 Finally, test_support.HOST has been introduced, which should be used
1769 for the host argument of any relevant socket calls (i.e. bind and
1770 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001771
1772 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001773 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001774 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1775 test_asynchat and test_socket_ssl.
1776
Georg Brandl3ee81df2008-05-17 18:14:43 +00001777 It is now possible for multiple instances of the regression test
1778 suite to run in parallel without issue.

1831
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00001832- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00001833 \Uxxxxxxxx did not accept values outside the Basic Multilingual
1834 Plane. This affected raw unicode literals and the
1835 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
1836 this case, like normal unicode literals and the 'unicode-escape'
1837 codec.

2045-----------------
2046
Fred Drakea8ee94b2008-03-01 02:45:07 +00002047- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002048 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002050- Issue #2067: file.__exit__() now calls subclasses' close() method.
2051
2052- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002053
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002054- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002055 issue 215555 for a discussion.
2056
Eric Smitha73fbe72008-02-23 03:09:44 +00002057- Added the future_builtins module, which contains hex() and oct().
2058 These are the PEP 3127 version of these functions, designed to be
2059 compatible with the hex() and oct() builtins from Python 3.0. They
2060 differ slightly in their output formats from the existing, unchanged
2061 Python 2.6 builtins. The expected usage of the future_builtins
2062 module is:
2063 from future_builtins import hex, oct
2064
Eric Smith7ef40bf2008-02-20 23:34:22 +00002065- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2066 exponents for exponents with absolute value < 100. Follows C99
2067 standard. This is a change on Windows, which would use 3 digits.
2068 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2069 so that any alterations it does to the resulting string will be
2070 available in stringlib/formatter.h (for float.__format__).
2071
Eric Smith5a3c1352008-02-19 13:21:56 +00002072- Implemented PEP 3101, Advanced String Formatting. This adds a new
2073 builtin format(); a format() method for str and unicode; a
2074 __format__() method to object, str, unicode, int, long, float, and
2075 datetime; the class string.Formatter; and the C API
2076 PyObject_Format().
2077
Georg Brandl3ee81df2008-05-17 18:14:43 +00002078- Fixed several potential crashes, all caused by specially crafted
2079 __del__ methods exploiting objects in temporarily inconsistent
2080 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002081
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002082- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002083 prevent a possible crash: an Abstract Base Class would try to access
2084 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002085

Georg Brandl3ee81df2008-05-17 18:14:43 +00002089- Clear all free lists during a gc.collect() of the highest generation
2090 in order to allow pymalloc to free more arenas. Python may give back
2091 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002092
Georg Brandl3ee81df2008-05-17 18:14:43 +00002093- Issue #2045: Fix an infinite recursion triggered when printing a
2094 subclass of collections.defaultdict, if its default_factory is set

Christian Heimesf75dbef2008-02-08 00:11:31 +00002097- Fixed a minor memory leak in dictobject.c. The content of the free
2098 list was not freed on interpreter shutdown.
2099
Georg Brandl3ee81df2008-05-17 18:14:43 +00002100- Limit free list of method and builtin function objects to 256
2101 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002102
Georg Brandl3ee81df2008-05-17 18:14:43 +00002103- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2104 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002105 to compact the internal free lists of pre-allocted ints and floats.
2106
Georg Brandl3ee81df2008-05-17 18:14:43 +00002107- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2108 calls. Python expected the return type int but the fork familie
2109 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002110
Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002123- Patch #1473257: generator objects gain a gi_code attribute. This is
2124 the same object as the func_code attribute of the function that
2125 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002126
Georg Brandl3ee81df2008-05-17 18:14:43 +00002127- Issue #1920: "while 0" statements were completely removed by the
2128 compiler, even in the presence of an "else" clause, which is
2129 supposed to be run when the condition is false. Now the compiler
2130 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002131
Guido van Rossumeead05f2008-01-24 18:21:02 +00002132- A few crashers fixed: weakref_in_del.py (issue #1377858);
2133 loosing_dict_ref.py (issue #1303614, test67.py);
2134 borrowed_ref_[34].py (not in tracker).
2135
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002136- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002137 suppressed while an extension is loaded by calling SetErrorMode in
2138 dynload_win.c. The error is still reported properly.
2139
Georg Brandl3ee81df2008-05-17 18:14:43 +00002140- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002141 several extension methods and modules do not work without unicode
2142 support.
2143
Georg Brandl26543b12008-01-21 18:36:51 +00002144- Issue #1882: when compiling code from a string, encoding cookies in the
2145 second line of code were not always recognized correctly.
2146
Georg Brandl14404b62008-01-19 19:27:05 +00002147- Issue #1679: "0x" was taken as a valid integer literal.
2148
Georg Brandl6caad7d2008-01-26 14:19:22 +00002149- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002150 added.
2151
Christian Heimesc94e2b52008-01-14 04:13:37 +00002152- sys.float_info / PyFloat_GetInfo: The floating point information
2153 object was converted from a dict to a specialized structseq object.
2154
Georg Brandl3ee81df2008-05-17 18:14:43 +00002155- Patch #1816: Added sys.flags structseq. It exposes the status of
2156 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002157
Georg Brandl3ee81df2008-05-17 18:14:43 +00002158- Objects/structseq.c: Implemented new structseq representation. The
2159 patch makes structseqs (e.g. the return value of os.stat) more
2160 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002161
Georg Brandl3ee81df2008-05-17 18:14:43 +00002162- Patch #1700288: added a type attribute cache that caches method
2163 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002164
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002165- Bug #1776: __import__() no longer accepts filenames on any platform.
2166 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002167

2171 envvar and sys.dont_write_bytecode attribute. All these can be set
2172 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002173
Georg Brandl3ee81df2008-05-17 18:14:43 +00002174- Improve some exception messages when Windows fails to load an
2175 extension module. Now we get for example '%1 is not a valid Win32
2176 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002177

Christian Heimes0a8143f2007-12-18 23:22:54 +00002183- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002184 and INF. float("nan"), float("inf") and float("-inf") now work on
2185 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002186
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187- Compiler now generates simpler and faster code for dictionary
2188 literals. The oparg for BUILD_MAP now indicates an estimated
2189 dictionary size. There is a new opcode, STORE_MAP, for adding
2190 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002219- Patch #1739468: Directories and zipfiles containing a __main__.py
2220 file can now be directly executed by passing their name to the
2221 interpreter. The directory/zipfile is automatically inserted as the
2222 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002223
Georg Brandl3ee81df2008-05-17 18:14:43 +00002224- Issue #1265: Fix a problem with sys.settrace, if the tracing
2225 function uses a generator expression when at the same time the
2226 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002227
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002228- sets and frozensets now have an isdisjoint() method.
2229

2231
Neal Norwitz44f326e2007-10-05 05:29:17 +00002232- Fix warnings found by the new version of the Coverity checker.
2233
Georg Brandl3ee81df2008-05-17 18:14:43 +00002234- The enumerate() builtin function is no longer bounded to sequences
2235 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2236 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002237
Georg Brandl3ee81df2008-05-17 18:14:43 +00002238- Issue #1686386: Tuple's tp_repr did not take into account the
2239 possibility of having a self-referential tuple, which is possible
2240 from C code. Nor did object's tp_str consider that a type's tp_str
2241 could do something that could lead to an inifinite recursion.
2242 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2243 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Issue #1164: It was possible to trigger deadlock when using the
2246 'print' statement to write to a file since the GIL was not released
2247 as needed. Now PyObject_Print() does the right thing along with
2248 various tp_print implementations of the built-in types and those in
2249 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002250
Georg Brandl3ee81df2008-05-17 18:14:43 +00002251- Issue #1147: Exceptions were directly allowing string exceptions in
2252 their throw() method even though string exceptions no longer
2253 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002254
Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002258- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002259 PyObject_Call() never calling back out to Python code to trigger
2260 recursion depth updates/checks. Required the creation of a static
2261 RuntimeError instance in case normalizing an exception put the
2262 recursion check value past its limit. Fixes crashers
2263 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002264

Neal Norwitz0ac60192007-05-27 04:08:54 +00002278- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002279 __*__ attributes. (Some already existed, e.g., __doc__ and
2280 __name__.)

2286 calls.
2287
Collin Winter62903052007-05-18 23:11:24 +00002288- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002289 "except E as target:". This is to provide forwards compatibility
2290 with Python 3.0.

2296
Vinay Sajip8549ce32007-05-06 17:53:37 +00002297- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002298 setting a plain string, ie don't expand to single letter identifiers.
2299
Raymond Hettinger13936692007-04-11 18:40:58 +00002300- Request #1191699: Slices can now be pickled.
2301
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002302- Request #1193128: str.translate() now allows a None argument for

2304 remaining characters.
2305
Georg Brandl5cb76c12007-03-21 09:00:39 +00002306- Patch #1682205: a TypeError while unpacking an iterable is no longer
2307 masked by a generic one with the message "unpack non-sequence".
2308
Neal Norwitzaa754b72007-03-21 06:39:48 +00002309- Remove unused file Python/fmod.c.
2310
Guido van Rossum143b5642007-03-23 04:58:42 +00002311- Bug #1683368: The object.__init__() and object.__new__() methods are
2312 now stricter in rejecting excess arguments. The only time when
2313 either allows excess arguments is when it is not overridden and the
2314 other one is. For backwards compatibility, when both are
2315 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002316 warning later). Also, type.__init__() insists on the same signature
2317 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002319- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2320 object to complex using its __complex__() method before falling back
2321 to the __float__() method. Therefore, the functions in the cmath
2322 module now can operate on objects that define a __complex__()
2323 method.

2333 ``object.__reduce_ex__()`` is called with an object that is faking
2334 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002335

2342 case, even when converting the value to a string failed.
2343
Georg Brandl871f1bc2007-03-12 13:17:36 +00002344- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002345 its argument, if it exists. If not, it will work like before. This
2346 allows customizing the output of dir() in the presence of a
2347 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002359- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002360 makes the filenames the warning module prints much more sensible
2361 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002374- Patch #1674228: when assigning a slice (old-style), check for the
2375 sq_ass_slice instead of the sq_slice slot.
2376
Georg Brandl3ee81df2008-05-17 18:14:43 +00002377- When printing an unraisable error, don't print exceptions. before
2378 the name. This duplicates the behavior whening normally printing
2379 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002387- Bug #1377858: Fix the segfaulting of the interpreter when an object
2388 created a weakref on itself during a __del__ call for new-style
2389 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00002429- Bug #1545497: when given an explicit base, int() did ignore NULs
2430 embedded in the string to convert.
2431
Georg Brandl846f73a2006-10-08 07:11:54 +00002432- Bug #1569998: break inside a try statement (outside a loop) is now
2433 recognized and rejected.
2434
Armin Rigo7ccbca92006-10-04 12:17:45 +00002435- list.pop(x) accepts any object x following the __index__ protocol.
2436
Armin Rigo7ccbca92006-10-04 12:17:45 +00002437- A number of places, including integer negation and absolute value,
2438 were fixed to not rely on undefined behaviour of the C compiler
2439 anymore.
Martin v. Löwis820d6ac2006-10-04 05:47:34 +00002440

Georg Brandl4e933132006-09-06 20:05:58 +00002462- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002480 generator expressions (x for x, in ... ) works again. Fixing this
2481 problem required changing the .pyc magic number. This means that
2482 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003294- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003295 that the SMTP.starttls() caller no longer needs to call ehlo()
3296 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297 does not claim to support starttls. Adds the
3298 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3299 Fenner.

3379 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3380 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003397 time so that opening a database previously created with the DB_DUP
3398 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3399 opens. Specifically: dictionary assignment to a DB object will
3400 replace all values for a given key when the database allows
3401 duplicate values. DB users should use DB.put(k, v) when they want
3402 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003403

3409 characters with ASCII value less than 32. Also, it correctly quotes
3410 dots only if they occur on a single line, as opposed to the previous
3411 behavior of quoting dots if they are the second character of any
3412 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003413
