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

360 traditional 2.x file object.

395 302 conformant loader) will now work correctly in most cases (they
396 are still subject to the constraints that exist for all code running
397 from inside a module loaded via a PEP 302 loader and attempting to

556What's New in Python 2.6.1
557==========================
558
559*Release date: 04-Dec-2008*
560
561Core and Builtins
562-----------------
563
564- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
565 interpreter to abort ("Fatal Python error: Could not reset the stack!")
566 instead of throwing a MemoryError.
567
568- Issue #4367: Python would segfault during compiling when the unicodedata
569 module couldn't be imported and \N escapes were present.
570
571- Issue #4348: Some bytearray methods returned that didn't cause any change to
572 the bytearray, returned the same bytearray instead of a copy.
573
574- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
575
576- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
577
578- Issue #4048: The parser module now correctly validates relative imports.
579
580- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
581 exec statement.
582
583- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
584 method does not return iterators for the 4th and 5th items.
585
586- Issue #4209: Enabling unicode_literals and the print_function in the same
587 __future__ import didn't work.
588
589- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
590 returned a path longer than MAX_PATH. (But It's doubtful this code path is
591 really executed because I cannot move to such directory on win2k)
592
593- Issue #4069: When set.remove(element) is used with a set element, the element
594 is temporarily replaced with an equivalent frozenset. But the eventual
595 KeyError would always report the empty frozenset([]) as the missing key. Now
596 it correctly refers to the initial element.
597
598- Fixed C99 style comments in several files. Python is now C89 compatible
599 again.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000746- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
747
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000748- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
749 PyString_FromFormat or PyErr_Format to display size_t values. The macro
750 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
751 ``printf`` function, whereas PyString_FromFormat has an independent
752 implementation and uses "%zd" on all platforms for size_t values.
753 This makes a difference on win64, where ``printf`` needs "%Id" to display
754 64bit values.
755
Benjamin Peterson97179b02008-09-09 20:55:01 +0000756- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
757 error.
758
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000759- Issue #3777: long() applied to a float object now always return a long
760 object; previously an int would be returned for small values. the __long__
761 method is allowed to return either an int or a long, but the behaviour of
762 float objects should not change to respect backward compatibility.
763
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000764- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +0000770 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000771 was correctly parsed but parsing of subsequent arguments failed.
772
Vinay Sajip35e3b032008-09-01 14:33:59 +0000773- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000774 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
775 mechanism. In the process, fix a bug where isinstance() and issubclass(),
776 when given a tuple of classes as second argument, were looking up
777 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
778 type object.

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

919Core and Builtins
920-----------------
921
Guido van Rossumf8402962008-08-20 15:01:50 +0000922- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
923 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
924 extensions do not automatically benefit from the class attribute
925 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
926 to their tp_flags field if they care. This is a backwards
927 compatibility feature; in 3.0, all types will use the cache by
928 default.
929
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000930- Keyword arguments can now follow starred arguments. (``f(a, *args,
931 keyword=23)`` is now valid syntax.)
932
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000933- ctypes function pointers that are COM methods have a boolean True
934 value again.
935
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000936- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
937 by denying s# to parse objects that have a releasebuffer procedure,
938 and introducing s*.
939
Georg Brandl1e13ea92008-08-11 09:07:59 +0000940- Issue #3537: Fix an assertion failure when an empty but presized dict
941 object was stored in the freelist.
942
Mark Dickinsonb6467572008-08-04 21:30:09 +0000943- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
944 ValueError consistently across platforms.
945
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000946- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
947 (64bit Unix, for example), unichr() would truncate its argument and return
948 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
949
Neal Norwitze7d8be82008-07-31 17:17:14 +0000950- Apply security patches from Apple.
951
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000952- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
953 PyErr_ExceptionMatches returns 0 when an exception occurs there.
954
Antoine Pitrou92f82162008-07-25 22:22:08 +0000955- Issue #1819: function calls with several named parameters are now on
956 average 35% faster (as measured by pybench).
957
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000958- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
959 the python debugger steps into a class statement: the free variables (local
960 variables defined in an outer scope) would be deleted from the outer scope.
961
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000962- Issue #2620: Overflow checking when allocating or reallocating memory
963 was not always being done properly in some python types and extension
964 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
965 all been updated to perform better checks and places in the code that
966 would previously leak memory on the error path when such an allocation
967 failed have been fixed.

973
Benjamin Petersone977ad42008-08-20 01:42:01 +0000974- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
975 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
976
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000977- Issue #2234: distutils failed for some versions of the cygwin compiler. The
978 version reported by these tools does not necessarily follow the python
979 version numbering scheme, so the module is less strict when parsing it.
980
Nick Coghlanf70385a2008-08-18 12:42:46 +0000981- Issue #2235: Added Py3k warnings for types which will become unhashable
982 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00001057 asking for a specific length. This problem only affected files opened

1100 interaction with the tp_hash slot (added in 2.6b2) are now documented
1101
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001102- Issue #643841: The language reference now provides more detailed

1110
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001111*Release date: 17-Jul-2008*
1112
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001113Core and Builtins
1114-----------------
1115
Georg Brandl3e483f62008-07-16 22:57:41 +00001116- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1117 its methods now allow for items objects that can be converted to
1118 an integer using operator.index().
1119
Mark Dickinson64b7e502008-07-16 09:40:03 +00001120- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1121 produced a ValueError instead of giving the correct float.
1122
Eric Smitha5fa5a22008-07-16 00:11:49 +00001123- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1124 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1125
Mark Dickinson7103aa42008-07-15 19:08:33 +00001126- Issue #3008: the float type has a new instance method 'float.hex'
1127 and a new class method 'float.fromhex' to convert floating-point
1128 numbers to and from hexadecimal strings, respectively.
1129
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001130- Issue #2235: __hash__ is once again inherited by default. To allow
1131 collections.Hashable to remain meaningful in the presence of the
1132 default hash implementation (object.__hash__), it is now possible
1133 to explicit block inheritance of hash by setting __hash__=None at
1134 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1135 level.
1136
Nick Coghlanb028f502008-07-13 14:52:36 +00001137- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1138 the parent module cannot be found while performing an absolute import.
1139 This means that an incorrectly defined __package__ attribute will
1140 now only prevent relative imports in that module rather than causing
1141 all imports from that module to fail.
1142
Nick Coghlan14ff9942008-07-08 14:21:42 +00001143- Issue #2517: Allow unicode messages in Exceptions again by correctly
1144 bypassing the instance dictionary when looking up __unicode__ on
1145 new-style classes.
1146

1148 set to a custom object whose write() method happens to install
1149 another file in sys.stdout.
1150
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001151- Issue #3088: Corrected a race condition in classes derived from
1152 threading.local: the first member set by a thread could be saved in
1153 another thread's dictionary.
1154
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001155- Issue #3004: Minor change to slice.indices(): the start and stop
1156 arguments are now treated identically, making the behaviour easier
1157 to describe and understand. For example, slice(None, -10,
1158 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1159 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1160 10, -1).
1161
Georg Brandl278fc502008-07-19 12:46:12 +00001162- Issue #3219: Calling a function with repeated keyword arguments,
1163 f(a=2, a=23), would not cause a syntax error. This was a regression
1164 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001165
Georg Brandl278fc502008-07-19 12:46:12 +00001166- Issue #2862: Make int and float freelist management consistent with
1167 other freelists. Changes their CompactFreeList apis into
1168 ClearFreeList apis and calls them via gc.collect().

1174 api functions without holding the GIL, which could lead to a fatal
1175 error when they failed.
1176
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001177- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001202- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1203 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001204 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001205 content-length. The problem had been corrected in the 2.4 branch, but never
1206 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001221- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00001612- On MacOS X it is now possible to install the framework in 64-bit
1613 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001614 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001615
1616 This is controlled by the configure argument ``--with-universal-archs``:
1617
1618 - ``--with-universal-archs=all``: install 4-way universal
1619
1620 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1621
1622 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1623
1624 This option should be used in combination with ``--enable-universalsdk=``.
1625
1626 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 +00001676- Issue #1631171: Re-implement the 'warnings' module in C (the
1677 original Python code has been kept as backup). This will allow for
1678 using the 'warning's machinery in such places as the parser where
1679 use of pure Python code is not possible. Both the ``showarning()``
1680 and ``formatwarning()`` gain an optional 'line' argument which is
1681 not called by default for backwards-compatibility reasons. Setting
1682 ``warnings.showwarning()`` to an implementation that lacks support
1683 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001746- Issue #2550: The approach used by client/server code for obtaining
1747 ports to listen on in network-oriented tests has been refined in an
1748 effort to facilitate running multiple instances of the entire
1749 regression test suite in parallel without issue.
1750 test_support.bind_port() has been fixed such that it will always
1751 return a unique port -- which wasn't always the case with the
1752 previous implementation, especially if socket options had been set
1753 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1754 new implementation of bind_port() will actually raise an exception
1755 if it is passed an AF_INET/SOCK_STREAM socket with either the
1756 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1757 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1758 the socket it's been passed. This currently only applies to
1759 Windows. This option prevents any other sockets from binding to the
1760 host/port we've bound to, thus removing the possibility of the
1761 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1762 when a second SOCK_STREAM socket binds and accepts to a host/port
1763 that's already been bound by another socket. The optional preferred
1764 port parameter to bind_port() has been removed. Under no
1765 circumstances should tests be hard coding ports!
1766
1767 test_support.find_unused_port() has also been introduced, which will
1768 pass a temporary socket object to bind_port() in order to obtain an
1769 unused port. The temporary socket object is then closed and
1770 deleted, and the port is returned. This method should only be used
1771 for obtaining an unused port in order to pass to an external program
1772 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1773 a parameter to a server-oriented class that doesn't give you direct
1774 access to the underlying socket used.
1775
1776 Finally, test_support.HOST has been introduced, which should be used
1777 for the host argument of any relevant socket calls (i.e. bind and
1778 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001779
1780 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001781 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001782 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1783 test_asynchat and test_socket_ssl.
1784
Georg Brandl3ee81df2008-05-17 18:14:43 +00001785 It is now possible for multiple instances of the regression test
1786 suite to run in parallel without issue.

1839
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00001840- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00001841 \Uxxxxxxxx did not accept values outside the Basic Multilingual
1842 Plane. This affected raw unicode literals and the
1843 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
1844 this case, like normal unicode literals and the 'unicode-escape'
1845 codec.

2053-----------------
2054
Fred Drakea8ee94b2008-03-01 02:45:07 +00002055- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002056 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002057
Georg Brandlad61bc82008-02-23 15:11:18 +00002058- Issue #2067: file.__exit__() now calls subclasses' close() method.
2059
2060- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002061
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002062- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002063 issue 215555 for a discussion.
2064
Eric Smitha73fbe72008-02-23 03:09:44 +00002065- Added the future_builtins module, which contains hex() and oct().
2066 These are the PEP 3127 version of these functions, designed to be
2067 compatible with the hex() and oct() builtins from Python 3.0. They
2068 differ slightly in their output formats from the existing, unchanged
2069 Python 2.6 builtins. The expected usage of the future_builtins
2070 module is:
2071 from future_builtins import hex, oct
2072
Eric Smith7ef40bf2008-02-20 23:34:22 +00002073- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2074 exponents for exponents with absolute value < 100. Follows C99
2075 standard. This is a change on Windows, which would use 3 digits.
2076 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2077 so that any alterations it does to the resulting string will be
2078 available in stringlib/formatter.h (for float.__format__).
2079
Eric Smith5a3c1352008-02-19 13:21:56 +00002080- Implemented PEP 3101, Advanced String Formatting. This adds a new
2081 builtin format(); a format() method for str and unicode; a
2082 __format__() method to object, str, unicode, int, long, float, and
2083 datetime; the class string.Formatter; and the C API
2084 PyObject_Format().
2085
Georg Brandl3ee81df2008-05-17 18:14:43 +00002086- Fixed several potential crashes, all caused by specially crafted
2087 __del__ methods exploiting objects in temporarily inconsistent
2088 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002089
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002090- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002091 prevent a possible crash: an Abstract Base Class would try to access
2092 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002093

Georg Brandl3ee81df2008-05-17 18:14:43 +00002097- Clear all free lists during a gc.collect() of the highest generation
2098 in order to allow pymalloc to free more arenas. Python may give back
2099 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002100
Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Issue #2045: Fix an infinite recursion triggered when printing a
2102 subclass of collections.defaultdict, if its default_factory is set
2103 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002111- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2112 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002113 to compact the internal free lists of pre-allocted ints and floats.
2114
Georg Brandl3ee81df2008-05-17 18:14:43 +00002115- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2116 calls. Python expected the return type int but the fork familie
2117 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002118
Georg Brandl3ee81df2008-05-17 18:14:43 +00002119- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002131- Patch #1473257: generator objects gain a gi_code attribute. This is
2132 the same object as the func_code attribute of the function that
2133 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002134
Georg Brandl3ee81df2008-05-17 18:14:43 +00002135- Issue #1920: "while 0" statements were completely removed by the
2136 compiler, even in the presence of an "else" clause, which is
2137 supposed to be run when the condition is false. Now the compiler
2138 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002139
Guido van Rossumeead05f2008-01-24 18:21:02 +00002140- A few crashers fixed: weakref_in_del.py (issue #1377858);
2141 loosing_dict_ref.py (issue #1303614, test67.py);
2142 borrowed_ref_[34].py (not in tracker).

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002144- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002145 suppressed while an extension is loaded by calling SetErrorMode in
2146 dynload_win.c. The error is still reported properly.
2147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002149 several extension methods and modules do not work without unicode
2150 support.
2151
Georg Brandl26543b12008-01-21 18:36:51 +00002152- Issue #1882: when compiling code from a string, encoding cookies in the

2156
Georg Brandl6caad7d2008-01-26 14:19:22 +00002157- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002158 added.
2159
Christian Heimesc94e2b52008-01-14 04:13:37 +00002160- sys.float_info / PyFloat_GetInfo: The floating point information
2161 object was converted from a dict to a specialized structseq object.
2162
Georg Brandl3ee81df2008-05-17 18:14:43 +00002163- Patch #1816: Added sys.flags structseq. It exposes the status of
2164 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002165
Georg Brandl3ee81df2008-05-17 18:14:43 +00002166- Objects/structseq.c: Implemented new structseq representation. The
2167 patch makes structseqs (e.g. the return value of os.stat) more
2168 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002169
Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Patch #1700288: added a type attribute cache that caches method
2171 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002172
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002173- Bug #1776: __import__() no longer accepts filenames on any platform.
2174 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002175

2179 envvar and sys.dont_write_bytecode attribute. All these can be set
2180 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Improve some exception messages when Windows fails to load an
2183 extension module. Now we get for example '%1 is not a valid Win32
2184 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002185

Georg Brandl3ee81df2008-05-17 18:14:43 +00002232- Issue #1265: Fix a problem with sys.settrace, if the tracing
2233 function uses a generator expression when at the same time the
2234 executed code is closing a paused generator.

2241
Georg Brandl3ee81df2008-05-17 18:14:43 +00002242- The enumerate() builtin function is no longer bounded to sequences
2243 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2244 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002245
Georg Brandl3ee81df2008-05-17 18:14:43 +00002246- Issue #1686386: Tuple's tp_repr did not take into account the
2247 possibility of having a self-referential tuple, which is possible
2248 from C code. Nor did object's tp_str consider that a type's tp_str
2249 could do something that could lead to an inifinite recursion.
2250 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2251 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002252
Georg Brandl3ee81df2008-05-17 18:14:43 +00002253- Issue #1164: It was possible to trigger deadlock when using the
2254 'print' statement to write to a file since the GIL was not released
2255 as needed. Now PyObject_Print() does the right thing along with
2256 various tp_print implementations of the built-in types and those in
2257 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002267 PyObject_Call() never calling back out to Python code to trigger
2268 recursion depth updates/checks. Required the creation of a static
2269 RuntimeError instance in case normalizing an exception put the
2270 recursion check value past its limit. Fixes crashers

2294 calls.
2295
Collin Winter62903052007-05-18 23:11:24 +00002296- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002297 "except E as target:". This is to provide forwards compatibility
2298 with Python 3.0.

2320 now stricter in rejecting excess arguments. The only time when
2321 either allows excess arguments is when it is not overridden and the
2322 other one is. For backwards compatibility, when both are
2323 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002324 warning later). Also, type.__init__() insists on the same signature
2325 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002327- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2328 object to complex using its __complex__() method before falling back
2329 to the __float__() method. Therefore, the functions in the cmath
2330 module now can operate on objects that define a __complex__()
2331 method.

2351
Georg Brandl871f1bc2007-03-12 13:17:36 +00002352- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002353 its argument, if it exists. If not, it will work like before. This
2354 allows customizing the output of dir() in the presence of a
2355 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002367- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002368 makes the filenames the warning module prints much more sensible
2369 when a PYTHONSTARTUP file is used.

2383 sq_ass_slice instead of the sq_slice slot.
2384
Georg Brandl3ee81df2008-05-17 18:14:43 +00002385- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00002437- Bug #1545497: when given an explicit base, int() did ignore NULs
2438 embedded in the string to convert.
2439
Georg Brandl846f73a2006-10-08 07:11:54 +00002440- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002488 generator expressions (x for x, in ... ) works again. Fixing this
2489 problem required changing the .pyc magic number. This means that
2490 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003297- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3298 with RFC 3207 and forgets any knowledge obtained from the server not
3299 obtained from the TLS negotiation itself. Patch contributed by Bill
3300 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003301
Georg Brandl3ee81df2008-05-17 18:14:43 +00003302- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003303 that the SMTP.starttls() caller no longer needs to call ehlo()
3304 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003305 does not claim to support starttls. Adds the
3306 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3307 Fenner.

3387 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3388 silently miscode subclasses of those types. Now, it raises a
3389 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003390

Georg Brandl3ee81df2008-05-17 18:14:43 +00003405 time so that opening a database previously created with the DB_DUP
3406 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3407 opens. Specifically: dictionary assignment to a DB object will
3408 replace all values for a given key when the database allows
3409 duplicate values. DB users should use DB.put(k, v) when they want
3410 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003411

3417 characters with ASCII value less than 32. Also, it correctly quotes
3418 dots only if they occur on a single line, as opposed to the previous
3419 behavior of quoting dots if they are the second character of any
3420 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003421
