39 exception of canonical and is_canonical) now accept instances of int
40 and long wherever a Decimal instance is accepted, and implicitly

90 and read operations on write-only file objects. On Windows, the system C
91 library would return a bogus result; on Solaris, it was possible to crash
92 the interpreter. Patch by Stefan Krah.

111 could crash in many places because of the PyByteArray_AS_STRING() macro
112 returning NULL. The macro now returns a statically allocated empty
113 string instead.

122 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +0000123 strings corresponding to subnormal values, (3) a memory leak for
124 some values large enough to cause overflow, and (4) a number of
125 flaws that could lead to incorrectly rounded results.

144 in XML processing instructions and comments. These raw characters are
145 allowed by the XML specification, and are necessary when outputting e.g.
146 PHP code in a processing instruction. Patch by Neil Muller.

156 Also, raise ValueError rather than TypeError when an unknown TIPC address
157 type is specified. Patch by Brian Curtin.

162 file position when calling `truncate()`. It would previously change the
163 file position to the given argument, which goes against the tradition of
164 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

169 :class:`zipfile.ZipExtFile` class used to represent files stored inside
170 an archive. The new implementation is significantly faster and can
171 be wrapped in a :class:`io.BufferedReader` object for more speedups.
172 It also solves an issue where interleaved calls to `read()` and
173 `readline()` give wrong results. Patch by Nir Aides.

184 encoded string for them. This ensure that the upload and register commands
185 send the right values to PyPI without any error.

Benjamin Petersonecdae192010-01-04 00:43:01 +0000265- The __complex__ method is now looked up on the class of instances to make it
266 consistent with other special methods.
267
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000268- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
269 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
270
Mark Dickinson1b34d252010-01-01 17:27:30 +0000271- Issue #5080: A number of functions and methods previously produced a
272 DeprecationWarning when passed a float argument where an integer was
273 expected. These functions and methods now raise TypeError instead.
274 The majority of the effects of this change are in the extension
275 modules, but some core functions and methods are affected: notably
276 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
277 methods.
278
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000279- Issue #7604: Deleting an unset slotted attribute did not raise an

287
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000288- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
289 used to drop the time part of the result.
290
Mark Dickinson46572832009-12-27 14:55:57 +0000291- Issue #1811: improve accuracy and cross-platform consistency for
292 true division of integers: the result of a/b is now correctly
293 rounded for ints a and b (at least on IEEE 754 platforms), and in
294 particular does not depend on the internal representation of a long.
295
Ezio Melottif84caf42009-12-24 22:25:17 +0000296- Issue #6108: unicode(exception) and str(exception) should return the same

298
Ronald Oussoren92919a62009-12-24 13:30:58 +0000299- Issue #6834: replace the implementation for the 'python' and 'pythonw'

Eric Smithc4ab8332009-11-29 17:40:57 +0000444- Issue #3382: 'F' formatting for float and complex now convert the
445 result to upper case. This only affects 'inf' and 'nan', since 'f'
446 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000447

460 on MacOSX 10.6.
461
Mark Dickinsonb678de82009-11-19 18:41:49 +0000462- Issue #7117: repr(x) for a float x returns a result based on the
463 shortest decimal string that's guaranteed to round back to x under
464 correct rounding (with round-half-to-even rounding mode).
465 Previously it gave a string based on rounding x to 17 decimal digits.
466 repr(x) for a complex number behaves similarly. On platforms where
467 the correctly-rounded strtod and dtoa code is not supported (see below),
468 repr is unchanged.
469
470- Issue #7117: On almost all platforms: float-to-string and
471 string-to-float conversions within Python are now correctly rounded.
472 Places these conversions occur include: str for floats and complex
473 numbers; the float and complex constructors; old-style and new-style
474 numeric formatting; serialization and deserialization of floats and
475 complex numbers using marshal, pickle and json; parsing of float and
476 imaginary literals in Python code; Decimal-to-float conversion.
477
478 The conversions use a Python-adapted version of David Gay's
479 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
480 functions. This code is supported on Windows, and on Unix-like
481 platforms using gcc, icc or suncc as the C compiler. There may be a
482 small number of platforms on which correct operation of this code
483 cannot be guaranteed, so the code is not used: notably, this applies
484 to platforms where the C double format is not IEEE 754 binary64, and
485 to platforms on x86 hardware where the x87 FPU is set to 64-bit
486 precision and Python's configure script is unable to determine how
487 to change the FPU precision. On these platforms conversions use the
488 platform strtod and dtoa, as before.
489
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000490- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000491 now uses the correctly-rounded string <-> float conversions
492 described above (when available), and so produces correctly rounded
493 results that will display nicely under the float repr. There are
494 two related small changes: (1) round now accepts any class with an
495 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000496 floats for the second argument), and (2) an excessively large second
497 integer argument (e.g., round(1.234, 10**100)) no longer raises an
498 exception.

Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000618 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000619
Raymond Hettinger578a2282009-05-29 04:58:52 +0000620- Issue #5982: staticmethod and classmethod now expose the wrapped
621 function with __func__.
622
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000623- Added support for multiple context managers in the same with-statement.
624 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +0000625
Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000626- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
627 statement and correctly lookup the __enter__ and __exit__ special methods.
628
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000629- Issue #5829: complex("1e500") no longer raises OverflowError. This
630 makes it consistent with float("1e500") and interpretation of real
631 and imaginary literals.
632
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000633- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
634
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000635- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
636 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000637
R. David Murray525cffc2009-05-13 13:07:14 +0000638- Issue #5994: the marshal module now has docstrings.
639
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000640- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
641 (1) inf and nan strings with trailing whitespace were incorrectly
642 rejected; (2) parsing of strings representing infinities and nans
643 was locale aware; and (3) the interpretation of fromhex('-nan')
644 didn't match that of float('-nan').
645
Eric Smitha985a3a2009-05-05 18:26:08 +0000646- Issue #5920: For float.__format__, change the behavior with the
647 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
648 to be like 'g' but with at least one decimal point and with a
649 default precision of 12. Previously, the behavior the same but with
650 a default precision of 6. This more closely matches str(), and
651 reduces surprises when adding alignment flags to the empty
652 presentation type. This also affects the new complex.__format__ in
653 the same way.
654
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000655- Issue #5890: in subclasses of 'property' the __doc__ attribute was
656 shadowed by classtype's, even if it was None. property now
657 inserts the __doc__ into the subclass instance __dict__.
658
Antoine Pitrou653dece2009-05-04 18:32:32 +0000659- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
660 sequences. Patch by Nick Barnes and Victor Stinner.
661
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000662- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000663 format(complex(1, 2./3), '.5') now produces a sensible result.
664
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000665- Issue #5864: Fix empty format code formatting for floats so that it
666 never gives more than the requested number of significant digits.
667
Eric Smithcac7af62009-04-27 19:04:37 +0000668- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

672 titlecase, but not their own uppercase.
673
Eric Smith068f0652009-04-25 21:40:15 +0000674- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
675 _PyOS_double_to_string or PyOS_double_to_string.
676
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000677- Issue #5283: Setting __class__ in __del__ caused a segfault.
678
Mark Dickinson95bc9802009-04-24 12:46:53 +0000679- Issue #5816: complex(repr(z)) now recovers z exactly, even when
680 z involves nans, infs or negative zeros.
681
Eric Smithaca19e62009-04-22 13:29:05 +0000682- Implement PEP 378, Format Specifier for Thousands Separator, for
683 floats, ints, and longs.
684
685- Issue #5515: 'n' formatting for ints, longs, and floats handles
686 leading zero formatting poorly.
687
688- Issue #5772: For float.__format__, don't add a trailing ".0" if
689 we're using no type code and we have an exponent.
690
Mark Dickinson6736cf82009-04-20 21:13:33 +0000691- Issue #3166: Make long -> float (and int -> float) conversions
692 correctly rounded.
693
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000694- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
695 some builtin types.
696
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000697- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000698 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000699
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000700- Issue #5759: float() didn't call __float__ on str subclasses.
701
Georg Brandl3c4a5462009-04-12 12:08:12 +0000702- Issue #5704: the "-3" command-line option now implies "-t".
703
R. David Murray0374a822009-04-09 21:54:50 +0000704- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
705 its clarity and its speed.
706
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000707- Issue #2396: the memoryview object was backported from Python 3.1.
708
Georg Brandld3f03fa2009-04-02 18:09:04 +0000709- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

Brett Cannon15ba4da2009-04-01 18:03:59 +0000712- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
713
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000714- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
715 the end sys.path, for compatibility with the system install of Python.
716
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000717- Issue #4688: Add a heuristic so that tuples and dicts containing only
718 untrackable objects are not tracked by the garbage collector. This can
719 reduce the size of collections and therefore the garbage collection overhead
720 on long-running programs, depending on their particular use of datatypes.
721
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000722- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
723 improve its performance. Long divisions and remainder operations
724 are now between 50% and 150% faster.
725
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000726- Issue #4258: Make it possible to use base 2**30 instead of base
727 2**15 for the internal representation of integers, for performance
728 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
729 --enable-big-digits option to configure, which overrides the
730 default. Add sys.long_info structseq to provide information about
731 the internal format.
732
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000733- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
734 result traceback.__members__ no longer exists.)
735
Mark Dickinson6b265f12009-03-18 16:07:26 +0000736- Issue #4474: PyUnicode_FromWideChar now converts characters outside
737 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
738 and sizeof(Py_UNICODE) == 2.
739
Eric Smith6f42edb2009-03-14 11:57:26 +0000740- Issue #5237: Allow auto-numbered fields in str.format(). For
741 example: '{} {}'.format(1, 2) == '1 2'.
742
Brett Cannon6c4cff02009-03-11 04:51:06 +0000743- Issue #3652: Make the 'line' argument for warnings.showwarning() a
744 requirement. Means the DeprecationWarning from Python 2.6 can go away.
745
Eric Smithe9fb6862009-02-20 14:02:36 +0000746- Issue #5247: Improve error message when unknown format codes are
747 used when using str.format() with str, unicode, long, int, and
748 float arguments.
749
Raymond Hettinger08259e82009-02-18 23:10:19 +0000750- Running Python with the -3 option now also warns about classic division
751 for ints and longs.
752
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000753- Issue #5260: Long integers now consume less memory: average
754 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
755 on a 64-bit system.
756
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000757- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
758 rotating the object pointer by 4 bits to the right.
759
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000760- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
761 it now forces its argument to double before testing for infinity.
762
Benjamin Petersone18ef192009-01-20 14:21:16 +0000763- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
764
Georg Brandl29c6a282009-04-05 20:23:13 +0000765- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000766 were suppressing all exceptions. These include list(), filter(), map(),
767 zip(), and bytearray().
768
Benjamin Peterson596d3062009-01-19 15:42:23 +0000769- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
770 functions.
771
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000772- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

776
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000777- Issue #4935: The overflow checking code in the expandtabs() method common
778 to str, bytes and bytearray could be optimized away by the compiler, letting
779 the interpreter segfault instead of raising an error.
780
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000781- Issue #3720: Fix a crash when an iterator modifies its class and removes its
782 __next__ method.
783
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000784- Issue #4893: Use NT threading on CE.

787
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000788- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
789 collecting the oldest generation) so that allocating lots of objects without
790 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000791 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000792 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

795
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000796- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
797 an existing .py counterpart, override the co_filename attributes of all
798 code objects if the original filename is obsolete (which can happen if the
799 file has been renamed, moved, or if it is accessed through different paths).
800 Patch by Ziga Seilnacht and Jean-Paul Calderone.
801
Martin v. Löwis5344c992009-01-02 20:32:55 +0000802- Issue #4075: Use OutputDebugStringW in Py_FatalError.
803
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000804- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
805 file with `str' filename on Windows.
806
Antoine Pitrouaa687902009-01-01 14:11:22 +0000807- Issue #3680: Reference cycles created through a dict, set or deque iterator
808 did not get collected.
809
Nick Coghlan180e4002008-12-30 01:18:48 +0000810- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
811 where the tp_hash and tp_dict slots are both NULL.
812
Benjamin Peterson7af65562008-12-29 17:56:58 +0000813- Issue #4764: With io.open, IOError.filename is set when trying to open a
814 directory on POSIX systems.
815
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000816- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
817 systems.
818

820 bytearray.translate(). It was always allowed for bytes.translate().
821
Skip Montanarof205c132008-12-23 03:30:15 +0000822- Added test case to ensure attempts to read from a file opened for writing
823 fail.
824
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000825- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
826 print elapsed times, not only when some objects are uncollectable /
827 unreachable. Original patch by Neil Schemenauer.
828
Mark Dickinson1a707982008-12-17 16:14:37 +0000829- Issue #3439: Add a bit_length method to int and long.

833
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000834- Issue #4597: Fixed exception handling when the __exit__ function of a
835 context manager returns a value that cannot be converted to a bool.
836
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000837- Issue #4597: Fixed several opcodes that weren't always propagating
838 exceptions.
839
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000840- Issue #4445: Replace "sizeof(PyStringObject)" with
841 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
842 str instances. On a typical machine this saves 3 bytes of memory
843 (on average) per string allocation.
844
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000845- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
846 interpreter to abort ("Fatal Python error: Could not reset the stack!")
847 instead of throwing a MemoryError.
848
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000849- Issue #3689: The list reversed iterator now supports __length_hint__
850 instead of __len__. Behavior now matches other reversed iterators.
851
Benjamin Petersonc078f922008-11-21 22:27:24 +0000852- Issue #4367: Python would segfault during compiling when the unicodedata
853 module couldn't be imported and \N escapes were present.
854
Vinay Sajip213faca2008-12-03 23:22:58 +0000855- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000856 method on file objects with closefd=False. The file descriptor is still
857 kept open but the file object behaves like a closed file. The ``FileIO``
858 object also got a new readonly attribute ``closefd``.
859
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000860- Issue #4348: Some bytearray methods returned that didn't cause any change to
861 the bytearray, returned the same bytearray instead of a copy.
862
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000863- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
864

866
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000867- Issue #4048: The parser module now correctly validates relative imports.
868
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000869- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
870 exec statement.
871
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000872- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
873 method does not return iterators for the 4th and 5th items.
874
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000875- Issue #4209: Enabling unicode_literals and the print_function in the same
876 __future__ import didn't work.
877
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000878- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000879 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000880
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000881- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
882 returned a path longer than MAX_PATH. (But It's doubtful this code path is
883 really executed because I cannot move to such directory on win2k)
884
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000885- Issue #4069: When set.remove(element) is used with a set element, the element
886 is temporarily replaced with an equivalent frozenset. But the eventual
887 KeyError would always report the empty frozenset([]) as the missing key. Now
888 it correctly refers to the initial element.
889
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000890- Issue #4509: Various issues surrounding resize of bytearray objects to
891 which there are buffer exports.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000908- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
909 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
910 step. This avoids problems with counting UTF-8 bytes that ignores the effect
911 of using the replace error handler in PyUnicode_DecodeUTF8().
912
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000913- Issue #3739: The unicode-internal encoder now reports the number of characters

917 pymalloc allocator will be automatically disabled when running under
918 Valgrind. This gives improved memory leak detection when running
919 under Valgrind, while taking advantage of pymalloc at other times.

2156 leak-chasing test runs give sensible results. The previous method of
2157 reaping threads could return successfully while some Thread objects were

2298
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002299- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2300
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002301- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2302 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2303 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2304 ``printf`` function, whereas PyString_FromFormat has an independent
2305 implementation and uses "%zd" on all platforms for size_t values.
2306 This makes a difference on win64, where ``printf`` needs "%Id" to display
2307 64bit values.
2308
Benjamin Peterson97179b02008-09-09 20:55:01 +00002309- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2310 error.
2311
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002312- Issue #3777: long() applied to a float object now always return a long
2313 object; previously an int would be returned for small values. the __long__
2314 method is allowed to return either an int or a long, but the behaviour of
2315 float objects should not change to respect backward compatibility.
2316
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002317- Issue #3751: str.rpartition would perform a left-partition when called with
2318 a unicode argument.
2319
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002320- Issue #3683: Fix compilation when --without-threads is given.
2321
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002322- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002323 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002324 was correctly parsed but parsing of subsequent arguments failed.
2325
Vinay Sajip35e3b032008-09-01 14:33:59 +00002326- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002327 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2328 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2329 when given a tuple of classes as second argument, were looking up
2330 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2331 type object.
2332
Neal Norwitz18aa3882008-08-24 05:04:52 +00002333- Fix crashes on memory allocation failure found with failmalloc.
2334
2335- Fix memory leaks found with valgrind and update suppressions file.
2336
2337- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2338
2339- Fix problem using wrong name in decimal module reported by pychecker.
2340
Christian Heimes7d4c3172008-08-22 19:47:25 +00002341- Silenced another compiler warning about a used but not defined
2342 function 'stringlib_contains_obj'.

2345 ``__delslice__``.
2346
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002347- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2348 library targets in the Makefile.
2349
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002350- Issue #1204: The configure script now tests for additional libraries
2351 that may be required when linking against readline. This fixes issues
2352 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00002375- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002376 return a list or None rather than a custom object.

2402 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2403 for catch_warnings() also led to an improvement in the raising of a
2404 DeprecationWarning related to warnings.warn_explicit().
2405
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002406- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002470What's New in Python 2.6 beta 3?
2471================================
2472
Barry Warsaw07a4a382008-08-21 01:15:08 +00002473*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002474
2475Core and Builtins
2476-----------------
2477
Guido van Rossumf8402962008-08-20 15:01:50 +00002478- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2479 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2480 extensions do not automatically benefit from the class attribute
2481 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2482 to their tp_flags field if they care. This is a backwards
2483 compatibility feature; in 3.0, all types will use the cache by
2484 default.
2485
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002486- Keyword arguments can now follow starred arguments. (``f(a, *args,
2487 keyword=23)`` is now valid syntax.)
2488
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002489- ctypes function pointers that are COM methods have a boolean True
2490 value again.
2491
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002492- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2493 by denying s# to parse objects that have a releasebuffer procedure,
2494 and introducing s*.
2495
Georg Brandl1e13ea92008-08-11 09:07:59 +00002496- Issue #3537: Fix an assertion failure when an empty but presized dict
2497 object was stored in the freelist.
2498
Mark Dickinsonb6467572008-08-04 21:30:09 +00002499- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2500 ValueError consistently across platforms.
2501
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002502- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2503 (64bit Unix, for example), unichr() would truncate its argument and return
2504 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2505
Neal Norwitze7d8be82008-07-31 17:17:14 +00002506- Apply security patches from Apple.
2507
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002508- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2509 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2510
Antoine Pitrou92f82162008-07-25 22:22:08 +00002511- Issue #1819: function calls with several named parameters are now on
2512 average 35% faster (as measured by pybench).
2513
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002514- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2515 the python debugger steps into a class statement: the free variables (local
2516 variables defined in an outer scope) would be deleted from the outer scope.
2517
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002518- Issue #2620: Overflow checking when allocating or reallocating memory
2519 was not always being done properly in some python types and extension
2520 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2521 all been updated to perform better checks and places in the code that
2522 would previously leak memory on the error path when such an allocation
2523 failed have been fixed.

2531 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2532
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002533- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2534 version reported by these tools does not necessarily follow the python
2535 version numbering scheme, so the module is less strict when parsing it.
2536
Nick Coghlanf70385a2008-08-18 12:42:46 +00002537- Issue #2235: Added Py3k warnings for types which will become unhashable
2538 under the stricter __hash__ inheritance rules in 3.0. Several types
2539 which did not meet the rules for hash invariants and were already
2540 unhashable in 3.0 have now been explicitly flagged as unhashable in
2541 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2542 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2543
Brett Cannon88f801d2008-08-18 00:46:22 +00002544- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2545 imported into the module but exposed as part of the module's API.
2546
Brett Cannon7b96f072008-08-18 00:41:11 +00002547- Remove an unneeded import of abc.ABCMeta from 'inspect'.

2552
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002553- Issue #3575: Incremental decoder's decode function now takes bytearray
2554 by using 's*' instead of 't#'.
2555
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002556- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002557 fails unicode conversion on 2nd parameter. (windows only)
2558
Facundo Batista94f243a2008-08-17 03:38:39 +00002559- Issue 2464. urllib2 now supports a malformation in the URL received
2560 in a redirect.

2591 to _sre.compile() will now be rejected. This should not affect anybody
2592 since the re.compile() function never generates invalid re-bytecode.

Antoine Pitroude781a42008-08-09 12:43:23 +00002613 asking for a specific length. This problem only affected files opened

2641 mode 0600 rather than 000 under Unix.
2642
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002643- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2657
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002658- Issue #643841: The language reference now provides more detailed

2670-----------------
2671
Georg Brandl3e483f62008-07-16 22:57:41 +00002672- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2673 its methods now allow for items objects that can be converted to
2674 an integer using operator.index().
2675
Mark Dickinson64b7e502008-07-16 09:40:03 +00002676- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2677 produced a ValueError instead of giving the correct float.
2678
Eric Smitha5fa5a22008-07-16 00:11:49 +00002679- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2680 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2681
Mark Dickinson7103aa42008-07-15 19:08:33 +00002682- Issue #3008: the float type has a new instance method 'float.hex'
2683 and a new class method 'float.fromhex' to convert floating-point
2684 numbers to and from hexadecimal strings, respectively.
2685
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002686- Issue #2235: __hash__ is once again inherited by default. To allow
2687 collections.Hashable to remain meaningful in the presence of the
2688 default hash implementation (object.__hash__), it is now possible
2689 to explicit block inheritance of hash by setting __hash__=None at
2690 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2691 level.
2692
Nick Coghlanb028f502008-07-13 14:52:36 +00002693- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2694 the parent module cannot be found while performing an absolute import.
2695 This means that an incorrectly defined __package__ attribute will
2696 now only prevent relative imports in that module rather than causing
2697 all imports from that module to fail.
2698
Nick Coghlan14ff9942008-07-08 14:21:42 +00002699- Issue #2517: Allow unicode messages in Exceptions again by correctly

2709 another thread's dictionary.
2710
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002711- Issue #3004: Minor change to slice.indices(): the start and stop
2712 arguments are now treated identically, making the behaviour easier
2713 to describe and understand. For example, slice(None, -10,
2714 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2715 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2716 10, -1).
2717
Georg Brandl278fc502008-07-19 12:46:12 +00002718- Issue #3219: Calling a function with repeated keyword arguments,
2719 f(a=2, a=23), would not cause a syntax error. This was a regression
2720 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002722- Issue #2862: Make int and float freelist management consistent with
2723 other freelists. Changes their CompactFreeList apis into

2730 api functions without holding the GIL, which could lead to a fatal
2731 error when they failed.
2732
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002733- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002758- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2759 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002760 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002761 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002777- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Brett Cannonb61d8012008-05-11 23:39:04 +00003166- ``Lib/lib-old`` is now added to sys.path.
3167
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003168- On MacOS X it is now possible to install the framework in 64-bit
3169 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003170 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003171
3172 This is controlled by the configure argument ``--with-universal-archs``:
3173
3174 - ``--with-universal-archs=all``: install 4-way universal
3175
3176 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3177
3178 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3179
3180 This option should be used in combination with ``--enable-universalsdk=``.
3181
3182 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 +00003232- Issue #1631171: Re-implement the 'warnings' module in C (the
3233 original Python code has been kept as backup). This will allow for
3234 using the 'warning's machinery in such places as the parser where
3235 use of pure Python code is not possible. Both the ``showarning()``
3236 and ``formatwarning()`` gain an optional 'line' argument which is
3237 not called by default for backwards-compatibility reasons. Setting
3238 ``warnings.showwarning()`` to an implementation that lacks support
3239 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003264- The getpass module has been improved on Unix. It now uses /dev/tty
3265 by default and uses stderr instead of stdout. A GetPassWarning is
3266 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003281- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003282 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003302- Issue #2550: The approach used by client/server code for obtaining
3303 ports to listen on in network-oriented tests has been refined in an
3304 effort to facilitate running multiple instances of the entire
3305 regression test suite in parallel without issue.
3306 test_support.bind_port() has been fixed such that it will always
3307 return a unique port -- which wasn't always the case with the
3308 previous implementation, especially if socket options had been set
3309 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3310 new implementation of bind_port() will actually raise an exception
3311 if it is passed an AF_INET/SOCK_STREAM socket with either the
3312 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3313 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3314 the socket it's been passed. This currently only applies to
3315 Windows. This option prevents any other sockets from binding to the
3316 host/port we've bound to, thus removing the possibility of the
3317 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3318 when a second SOCK_STREAM socket binds and accepts to a host/port
3319 that's already been bound by another socket. The optional preferred
3320 port parameter to bind_port() has been removed. Under no
3321 circumstances should tests be hard coding ports!
3322
3323 test_support.find_unused_port() has also been introduced, which will
3324 pass a temporary socket object to bind_port() in order to obtain an
3325 unused port. The temporary socket object is then closed and
3326 deleted, and the port is returned. This method should only be used
3327 for obtaining an unused port in order to pass to an external program
3328 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3329 a parameter to a server-oriented class that doesn't give you direct
3330 access to the underlying socket used.
3331
3332 Finally, test_support.HOST has been introduced, which should be used
3333 for the host argument of any relevant socket calls (i.e. bind and
3334 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003335
3336 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003337 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003338 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3339 test_asynchat and test_socket_ssl.
3340
Georg Brandl3ee81df2008-05-17 18:14:43 +00003341 It is now possible for multiple instances of the regression test
3342 suite to run in parallel without issue.

3609-----------------
3610
Fred Drakea8ee94b2008-03-01 02:45:07 +00003611- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003612 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003617
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003618- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003619 issue 215555 for a discussion.
3620
Eric Smitha73fbe72008-02-23 03:09:44 +00003621- Added the future_builtins module, which contains hex() and oct().
3622 These are the PEP 3127 version of these functions, designed to be
3623 compatible with the hex() and oct() builtins from Python 3.0. They
3624 differ slightly in their output formats from the existing, unchanged
3625 Python 2.6 builtins. The expected usage of the future_builtins
3626 module is:
3627 from future_builtins import hex, oct
3628
Eric Smith7ef40bf2008-02-20 23:34:22 +00003629- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3630 exponents for exponents with absolute value < 100. Follows C99
3631 standard. This is a change on Windows, which would use 3 digits.
3632 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3633 so that any alterations it does to the resulting string will be
3634 available in stringlib/formatter.h (for float.__format__).
3635
Eric Smith5a3c1352008-02-19 13:21:56 +00003636- Implemented PEP 3101, Advanced String Formatting. This adds a new
3637 builtin format(); a format() method for str and unicode; a
3638 __format__() method to object, str, unicode, int, long, float, and
3639 datetime; the class string.Formatter; and the C API
3640 PyObject_Format().
3641
Georg Brandl3ee81df2008-05-17 18:14:43 +00003642- Fixed several potential crashes, all caused by specially crafted
3643 __del__ methods exploiting objects in temporarily inconsistent
3644 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003645
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003646- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003647 prevent a possible crash: an Abstract Base Class would try to access
3648 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003649
Georg Brandl3ee81df2008-05-17 18:14:43 +00003650- Fixed repr() and str() of complex numbers with infinity or nan as
3651 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003652
Georg Brandl3ee81df2008-05-17 18:14:43 +00003653- Clear all free lists during a gc.collect() of the highest generation
3654 in order to allow pymalloc to free more arenas. Python may give back
3655 memory to the OS earlier.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003657- Issue #2045: Fix an infinite recursion triggered when printing a
3658 subclass of collections.defaultdict, if its default_factory is set
3659 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003660
Christian Heimesf75dbef2008-02-08 00:11:31 +00003661- Fixed a minor memory leak in dictobject.c. The content of the free
3662 list was not freed on interpreter shutdown.
3663
Georg Brandl3ee81df2008-05-17 18:14:43 +00003664- Limit free list of method and builtin function objects to 256
3665 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003666
Georg Brandl3ee81df2008-05-17 18:14:43 +00003667- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3668 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003669 to compact the internal free lists of pre-allocted ints and floats.
3670
Georg Brandl3ee81df2008-05-17 18:14:43 +00003671- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3672 calls. Python expected the return type int but the fork familie
3673 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003674
Georg Brandl3ee81df2008-05-17 18:14:43 +00003675- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3676 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003677
Georg Brandl3ee81df2008-05-17 18:14:43 +00003678- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3679 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003680
Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003684- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3685 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003686
Georg Brandl3ee81df2008-05-17 18:14:43 +00003687- Patch #1473257: generator objects gain a gi_code attribute. This is
3688 the same object as the func_code attribute of the function that
3689 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003690
Georg Brandl3ee81df2008-05-17 18:14:43 +00003691- Issue #1920: "while 0" statements were completely removed by the
3692 compiler, even in the presence of an "else" clause, which is
3693 supposed to be run when the condition is false. Now the compiler
3694 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003695
Guido van Rossumeead05f2008-01-24 18:21:02 +00003696- A few crashers fixed: weakref_in_del.py (issue #1377858);
3697 loosing_dict_ref.py (issue #1303614, test67.py);
3698 borrowed_ref_[34].py (not in tracker).
3699
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003700- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003701 suppressed while an extension is loaded by calling SetErrorMode in
3702 dynload_win.c. The error is still reported properly.
3703
Georg Brandl3ee81df2008-05-17 18:14:43 +00003704- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003705 several extension methods and modules do not work without unicode
3706 support.
3707
Georg Brandl26543b12008-01-21 18:36:51 +00003708- Issue #1882: when compiling code from a string, encoding cookies in the
3709 second line of code were not always recognized correctly.
3710
Georg Brandl14404b62008-01-19 19:27:05 +00003711- Issue #1679: "0x" was taken as a valid integer literal.
3712
Georg Brandl6caad7d2008-01-26 14:19:22 +00003713- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003714 added.
3715
Christian Heimesc94e2b52008-01-14 04:13:37 +00003716- sys.float_info / PyFloat_GetInfo: The floating point information
3717 object was converted from a dict to a specialized structseq object.
3718
Georg Brandl3ee81df2008-05-17 18:14:43 +00003719- Patch #1816: Added sys.flags structseq. It exposes the status of
3720 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003721
Georg Brandl3ee81df2008-05-17 18:14:43 +00003722- Objects/structseq.c: Implemented new structseq representation. The
3723 patch makes structseqs (e.g. the return value of os.stat) more
3724 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003725
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726- Patch #1700288: added a type attribute cache that caches method
3727 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003728
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003729- Bug #1776: __import__() no longer accepts filenames on any platform.
3730 The first parameter to __import__() must be a valid module name.

3733
Georg Brandl3ee81df2008-05-17 18:14:43 +00003734- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3735 envvar and sys.dont_write_bytecode attribute. All these can be set
3736 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003737
Georg Brandl3ee81df2008-05-17 18:14:43 +00003738- Improve some exception messages when Windows fails to load an
3739 extension module. Now we get for example '%1 is not a valid Win32
3740 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003741

Christian Heimes0a8143f2007-12-18 23:22:54 +00003747- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003748 and INF. float("nan"), float("inf") and float("-inf") now work on
3749 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003750
Georg Brandl3ee81df2008-05-17 18:14:43 +00003751- Compiler now generates simpler and faster code for dictionary
3752 literals. The oparg for BUILD_MAP now indicates an estimated
3753 dictionary size. There is a new opcode, STORE_MAP, for adding
3754 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003783- Patch #1739468: Directories and zipfiles containing a __main__.py
3784 file can now be directly executed by passing their name to the
3785 interpreter. The directory/zipfile is automatically inserted as the
3786 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003787
Georg Brandl3ee81df2008-05-17 18:14:43 +00003788- Issue #1265: Fix a problem with sys.settrace, if the tracing
3789 function uses a generator expression when at the same time the
3790 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003791
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003792- sets and frozensets now have an isdisjoint() method.
3793

3795
Neal Norwitz44f326e2007-10-05 05:29:17 +00003796- Fix warnings found by the new version of the Coverity checker.
3797
Georg Brandl3ee81df2008-05-17 18:14:43 +00003798- The enumerate() builtin function is no longer bounded to sequences
3799 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3800 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003801
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802- Issue #1686386: Tuple's tp_repr did not take into account the
3803 possibility of having a self-referential tuple, which is possible
3804 from C code. Nor did object's tp_str consider that a type's tp_str
3805 could do something that could lead to an inifinite recursion.
3806 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3807 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003808
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809- Issue #1164: It was possible to trigger deadlock when using the
3810 'print' statement to write to a file since the GIL was not released
3811 as needed. Now PyObject_Print() does the right thing along with
3812 various tp_print implementations of the built-in types and those in
3813 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003814
Georg Brandl3ee81df2008-05-17 18:14:43 +00003815- Issue #1147: Exceptions were directly allowing string exceptions in
3816 their throw() method even though string exceptions no longer
3817 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003818
Georg Brandl3ee81df2008-05-17 18:14:43 +00003819- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00003821
Brett Cannon1e534b52007-09-07 04:18:30 +00003822- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003823 PyObject_Call() never calling back out to Python code to trigger
3824 recursion depth updates/checks. Required the creation of a static
3825 RuntimeError instance in case normalizing an exception put the
3826 recursion check value past its limit. Fixes crashers
3827 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003828

Neal Norwitz0ac60192007-05-27 04:08:54 +00003842- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003843 __*__ attributes. (Some already existed, e.g., __doc__ and
3844 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003845
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003846- Add -3 option to the interpreter to warn about features that are
3847 deprecated and will be changed/removed in Python 3.0.
3848
Georg Brandl2134e752007-05-21 20:34:16 +00003849- Patch #1686487: you can now pass any mapping after '**' in function
3850 calls.
3851
Collin Winter62903052007-05-18 23:11:24 +00003852- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003853 "except E as target:". This is to provide forwards compatibility
3854 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00003856- Deprecate BaseException.message as per PEP 352.
3857
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- Issue #1303614: don't expose object's __dict__ when the dict is

3860
Vinay Sajip8549ce32007-05-06 17:53:37 +00003861- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003862 setting a plain string, ie don't expand to single letter identifiers.
3863
Raymond Hettinger13936692007-04-11 18:40:58 +00003864- Request #1191699: Slices can now be pickled.
3865
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003866- Request #1193128: str.translate() now allows a None argument for
3867 translations that only remove characters without re-mapping the
3868 remaining characters.
3869
Georg Brandl5cb76c12007-03-21 09:00:39 +00003870- Patch #1682205: a TypeError while unpacking an iterable is no longer
3871 masked by a generic one with the message "unpack non-sequence".
3872
Neal Norwitzaa754b72007-03-21 06:39:48 +00003873- Remove unused file Python/fmod.c.
3874
Guido van Rossum143b5642007-03-23 04:58:42 +00003875- Bug #1683368: The object.__init__() and object.__new__() methods are
3876 now stricter in rejecting excess arguments. The only time when
3877 either allows excess arguments is when it is not overridden and the
3878 other one is. For backwards compatibility, when both are
3879 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003880 warning later). Also, type.__init__() insists on the same signature
3881 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003883- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3884 object to complex using its __complex__() method before falling back
3885 to the __float__() method. Therefore, the functions in the cmath
3886 module now can operate on objects that define a __complex__()
3887 method.

Georg Brandlaa2321b2007-03-07 00:40:28 +00003923- Patch #703779: unset __file__ in __main__ after running a file. This

3994 embedded in the string to convert.
3995
Georg Brandl846f73a2006-10-08 07:11:54 +00003996- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004435 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004476 AttributeError instead of an IOError when the server's response
4477 didn't contain a valid HTTP status line.

4509
Georg Brandl92a6bae2007-03-13 17:43:32 +00004510- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004511 are set for invalid interpolation sequences that would lead to
4512 errors on reading back those values.

4568 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004961 time so that opening a database previously created with the DB_DUP
4962 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4963 opens. Specifically: dictionary assignment to a DB object will
4964 replace all values for a given key when the database allows
4965 duplicate values. DB users should use DB.put(k, v) when they want
4966 to store duplicates; not DB[k] = v.

4973 characters with ASCII value less than 32. Also, it correctly quotes
4974 dots only if they occur on a single line, as opposed to the previous
4975 behavior of quoting dots if they are the second character of any
4976 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004977
