102 some values large enough to cause overflow, and (4) a number of
103 flaws that could lead to incorrectly rounded results.

140 file position when calling `truncate()`. It would previously change the
141 file position to the given argument, which goes against the tradition of

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

242
Benjamin Petersonecdae192010-01-04 00:43:01 +0000243- The __complex__ method is now looked up on the class of instances to make it
244 consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000246- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
247 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
248
Mark Dickinson1b34d252010-01-01 17:27:30 +0000249- Issue #5080: A number of functions and methods previously produced a
250 DeprecationWarning when passed a float argument where an integer was
251 expected. These functions and methods now raise TypeError instead.
252 The majority of the effects of this change are in the extension
253 modules, but some core functions and methods are affected: notably
254 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
255 methods.
256
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000257- Issue #7604: Deleting an unset slotted attribute did not raise an

265
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000266- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
267 used to drop the time part of the result.
268
Mark Dickinson46572832009-12-27 14:55:57 +0000269- Issue #1811: improve accuracy and cross-platform consistency for
270 true division of integers: the result of a/b is now correctly
271 rounded for ints a and b (at least on IEEE 754 platforms), and in
272 particular does not depend on the internal representation of a long.
273
Ezio Melottif84caf42009-12-24 22:25:17 +0000274- Issue #6108: unicode(exception) and str(exception) should return the same
275 message when only __str__ (and not __unicode__) is overridden in the subclass.
276
Ronald Oussoren92919a62009-12-24 13:30:58 +0000277- Issue #6834: replace the implementation for the 'python' and 'pythonw'
278 executables on OSX.
279

281 ``arch -ppc python`` will start a universal binary version of python
282 in PPC mode (unlike previous releases).

421
Eric Smithc4ab8332009-11-29 17:40:57 +0000422- Issue #3382: 'F' formatting for float and complex now convert the
423 result to upper case. This only affects 'inf' and 'nan', since 'f'
424 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000425

430 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
431 requested 120 significant digits instead.

438 on MacOSX 10.6.
439
Mark Dickinsonb678de82009-11-19 18:41:49 +0000440- Issue #7117: repr(x) for a float x returns a result based on the
441 shortest decimal string that's guaranteed to round back to x under
442 correct rounding (with round-half-to-even rounding mode).
443 Previously it gave a string based on rounding x to 17 decimal digits.
444 repr(x) for a complex number behaves similarly. On platforms where
445 the correctly-rounded strtod and dtoa code is not supported (see below),
446 repr is unchanged.
447
448- Issue #7117: On almost all platforms: float-to-string and
449 string-to-float conversions within Python are now correctly rounded.
450 Places these conversions occur include: str for floats and complex
451 numbers; the float and complex constructors; old-style and new-style
452 numeric formatting; serialization and deserialization of floats and
453 complex numbers using marshal, pickle and json; parsing of float and
454 imaginary literals in Python code; Decimal-to-float conversion.
455
456 The conversions use a Python-adapted version of David Gay's
457 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
458 functions. This code is supported on Windows, and on Unix-like
459 platforms using gcc, icc or suncc as the C compiler. There may be a
460 small number of platforms on which correct operation of this code
461 cannot be guaranteed, so the code is not used: notably, this applies
462 to platforms where the C double format is not IEEE 754 binary64, and
463 to platforms on x86 hardware where the x87 FPU is set to 64-bit
464 precision and Python's configure script is unable to determine how
465 to change the FPU precision. On these platforms conversions use the
466 platform strtod and dtoa, as before.
467
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000468- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000469 now uses the correctly-rounded string <-> float conversions
470 described above (when available), and so produces correctly rounded
471 results that will display nicely under the float repr. There are
472 two related small changes: (1) round now accepts any class with an
473 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000474 floats for the second argument), and (2) an excessively large second
475 integer argument (e.g., round(1.234, 10**100)) no longer raises an
476 exception.

R. David Murray525cffc2009-05-13 13:07:14 +0000616- Issue #5994: the marshal module now has docstrings.
617
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000618- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
619 (1) inf and nan strings with trailing whitespace were incorrectly
620 rejected; (2) parsing of strings representing infinities and nans
621 was locale aware; and (3) the interpretation of fromhex('-nan')
622 didn't match that of float('-nan').
623
Eric Smitha985a3a2009-05-05 18:26:08 +0000624- Issue #5920: For float.__format__, change the behavior with the
625 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
626 to be like 'g' but with at least one decimal point and with a
627 default precision of 12. Previously, the behavior the same but with
628 a default precision of 6. This more closely matches str(), and
629 reduces surprises when adding alignment flags to the empty
630 presentation type. This also affects the new complex.__format__ in
631 the same way.
632
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000633- Issue #5890: in subclasses of 'property' the __doc__ attribute was
634 shadowed by classtype's, even if it was None. property now
635 inserts the __doc__ into the subclass instance __dict__.
636
Antoine Pitrou653dece2009-05-04 18:32:32 +0000637- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
638 sequences. Patch by Nick Barnes and Victor Stinner.
639
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000640- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000641 format(complex(1, 2./3), '.5') now produces a sensible result.
642
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000643- Issue #5864: Fix empty format code formatting for floats so that it
644 never gives more than the requested number of significant digits.
645
Eric Smithcac7af62009-04-27 19:04:37 +0000646- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
647 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
648
Martin v. Löwis99f27792009-04-26 00:53:18 +0000649- Issue #4971: Fix titlecase for characters that are their own
650 titlecase, but not their own uppercase.
651
Eric Smith068f0652009-04-25 21:40:15 +0000652- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
653 _PyOS_double_to_string or PyOS_double_to_string.
654
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000655- Issue #5283: Setting __class__ in __del__ caused a segfault.
656
Mark Dickinson95bc9802009-04-24 12:46:53 +0000657- Issue #5816: complex(repr(z)) now recovers z exactly, even when
658 z involves nans, infs or negative zeros.
659
Eric Smithaca19e62009-04-22 13:29:05 +0000660- Implement PEP 378, Format Specifier for Thousands Separator, for
661 floats, ints, and longs.
662
663- Issue #5515: 'n' formatting for ints, longs, and floats handles
664 leading zero formatting poorly.
665
666- Issue #5772: For float.__format__, don't add a trailing ".0" if
667 we're using no type code and we have an exponent.
668
Mark Dickinson6736cf82009-04-20 21:13:33 +0000669- Issue #3166: Make long -> float (and int -> float) conversions
670 correctly rounded.
671
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000672- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
673 some builtin types.
674
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000675- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000676 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000677
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000678- Issue #5759: float() didn't call __float__ on str subclasses.
679
Georg Brandl3c4a5462009-04-12 12:08:12 +0000680- Issue #5704: the "-3" command-line option now implies "-t".
681
R. David Murray0374a822009-04-09 21:54:50 +0000682- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
683 its clarity and its speed.
684
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000685- Issue #2396: the memoryview object was backported from Python 3.1.
686

691
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000692- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
693 the end sys.path, for compatibility with the system install of Python.
694
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000695- Issue #4688: Add a heuristic so that tuples and dicts containing only
696 untrackable objects are not tracked by the garbage collector. This can
697 reduce the size of collections and therefore the garbage collection overhead
698 on long-running programs, depending on their particular use of datatypes.
699
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000700- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
701 improve its performance. Long divisions and remainder operations
702 are now between 50% and 150% faster.
703
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000704- Issue #4258: Make it possible to use base 2**30 instead of base
705 2**15 for the internal representation of integers, for performance
706 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
707 --enable-big-digits option to configure, which overrides the
708 default. Add sys.long_info structseq to provide information about
709 the internal format.
710
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000711- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
712 result traceback.__members__ no longer exists.)
713
Mark Dickinson6b265f12009-03-18 16:07:26 +0000714- Issue #4474: PyUnicode_FromWideChar now converts characters outside
715 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
716 and sizeof(Py_UNICODE) == 2.
717
Eric Smith6f42edb2009-03-14 11:57:26 +0000718- Issue #5237: Allow auto-numbered fields in str.format(). For
719 example: '{} {}'.format(1, 2) == '1 2'.
720
Brett Cannon6c4cff02009-03-11 04:51:06 +0000721- Issue #3652: Make the 'line' argument for warnings.showwarning() a
722 requirement. Means the DeprecationWarning from Python 2.6 can go away.
723
Eric Smithe9fb6862009-02-20 14:02:36 +0000724- Issue #5247: Improve error message when unknown format codes are
725 used when using str.format() with str, unicode, long, int, and
726 float arguments.
727
Raymond Hettinger08259e82009-02-18 23:10:19 +0000728- Running Python with the -3 option now also warns about classic division
729 for ints and longs.
730
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000731- Issue #5260: Long integers now consume less memory: average
732 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
733 on a 64-bit system.
734
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000735- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
736 rotating the object pointer by 4 bits to the right.
737
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000738- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
739 it now forces its argument to double before testing for infinity.
740
Benjamin Petersone18ef192009-01-20 14:21:16 +0000741- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
742
Georg Brandl29c6a282009-04-05 20:23:13 +0000743- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000744 were suppressing all exceptions. These include list(), filter(), map(),
745 zip(), and bytearray().
746
Benjamin Peterson596d3062009-01-19 15:42:23 +0000747- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
748 functions.
749
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000750- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
751 OSError.
752

754
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000755- Issue #4935: The overflow checking code in the expandtabs() method common
756 to str, bytes and bytearray could be optimized away by the compiler, letting
757 the interpreter segfault instead of raising an error.
758
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000759- Issue #3720: Fix a crash when an iterator modifies its class and removes its
760 __next__ method.
761
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000762- Issue #4893: Use NT threading on CE.
763

765
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000766- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
767 collecting the oldest generation) so that allocating lots of objects without
768 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000769 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000770 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

773
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000774- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
775 an existing .py counterpart, override the co_filename attributes of all
776 code objects if the original filename is obsolete (which can happen if the
777 file has been renamed, moved, or if it is accessed through different paths).
778 Patch by Ziga Seilnacht and Jean-Paul Calderone.
779
Martin v. Löwis5344c992009-01-02 20:32:55 +0000780- Issue #4075: Use OutputDebugStringW in Py_FatalError.
781
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000782- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
783 file with `str' filename on Windows.
784
Antoine Pitrouaa687902009-01-01 14:11:22 +0000785- Issue #3680: Reference cycles created through a dict, set or deque iterator
786 did not get collected.
787
Nick Coghlan180e4002008-12-30 01:18:48 +0000788- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
789 where the tp_hash and tp_dict slots are both NULL.
790
Benjamin Peterson7af65562008-12-29 17:56:58 +0000791- Issue #4764: With io.open, IOError.filename is set when trying to open a
792 directory on POSIX systems.
793
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000794- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
795 systems.
796
Georg Brandl6425a2f2008-12-28 11:54:53 +0000797- Issue #4759: None is now allowed as the first argument of
798 bytearray.translate(). It was always allowed for bytes.translate().
799
Skip Montanarof205c132008-12-23 03:30:15 +0000800- Added test case to ensure attempts to read from a file opened for writing
801 fail.
802
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000803- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
804 print elapsed times, not only when some objects are uncollectable /
805 unreachable. Original patch by Neil Schemenauer.
806
Mark Dickinson1a707982008-12-17 16:14:37 +0000807- Issue #3439: Add a bit_length method to int and long.
808
Antoine Pitroud0c35152008-12-17 00:38:28 +0000809- Issue #2183: Simplify and optimize bytecode for list comprehensions.
810 Original patch by Neal Norwitz.
811
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000812- Issue #4597: Fixed exception handling when the __exit__ function of a
813 context manager returns a value that cannot be converted to a bool.
814
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000815- Issue #4597: Fixed several opcodes that weren't always propagating
816 exceptions.
817
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000818- Issue #4445: Replace "sizeof(PyStringObject)" with
819 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
820 str instances. On a typical machine this saves 3 bytes of memory
821 (on average) per string allocation.
822
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000823- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
824 interpreter to abort ("Fatal Python error: Could not reset the stack!")
825 instead of throwing a MemoryError.
826
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000827- Issue #3689: The list reversed iterator now supports __length_hint__
828 instead of __len__. Behavior now matches other reversed iterators.
829
Benjamin Petersonc078f922008-11-21 22:27:24 +0000830- Issue #4367: Python would segfault during compiling when the unicodedata
831 module couldn't be imported and \N escapes were present.
832
Vinay Sajip213faca2008-12-03 23:22:58 +0000833- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000834 method on file objects with closefd=False. The file descriptor is still
835 kept open but the file object behaves like a closed file. The ``FileIO``
836 object also got a new readonly attribute ``closefd``.
837
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000838- Issue #4348: Some bytearray methods returned that didn't cause any change to
839 the bytearray, returned the same bytearray instead of a copy.
840
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000841- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
842
Benjamin Peterson273c2332008-11-17 22:39:09 +0000843- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
844
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000845- Issue #4048: The parser module now correctly validates relative imports.
846
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000847- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
848 exec statement.
849
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000850- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
851 method does not return iterators for the 4th and 5th items.
852
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000853- Issue #4209: Enabling unicode_literals and the print_function in the same
854 __future__ import didn't work.
855
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000856- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000857 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000858
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000859- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
860 returned a path longer than MAX_PATH. (But It's doubtful this code path is
861 really executed because I cannot move to such directory on win2k)
862
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000863- Issue #4069: When set.remove(element) is used with a set element, the element
864 is temporarily replaced with an equivalent frozenset. But the eventual
865 KeyError would always report the empty frozenset([]) as the missing key. Now
866 it correctly refers to the initial element.
867
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000868- Issue #4509: Various issues surrounding resize of bytearray objects to
869 which there are buffer exports.

879
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000880- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
881 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000882
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000883- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
884 returned them on 64bit platforms.
885
Walter Dörwalded960ac2009-05-03 22:36:33 +0000886- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
887 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
888 step. This avoids problems with counting UTF-8 bytes that ignores the effect
889 of using the replace error handler in PyUnicode_DecodeUTF8().
890
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000891- Issue #3739: The unicode-internal encoder now reports the number of characters
892 consumed like any other encoder (instead of the number of bytes).
893
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000894- Issue #2422: When compiled with the ``--with-valgrind`` option, the
895 pymalloc allocator will be automatically disabled when running under
896 Valgrind. This gives improved memory leak detection when running
897 under Valgrind, while taking advantage of pymalloc at other times.

2134 leak-chasing test runs give sensible results. The previous method of

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002277- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2278
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002279- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2280 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2281 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2282 ``printf`` function, whereas PyString_FromFormat has an independent
2283 implementation and uses "%zd" on all platforms for size_t values.
2284 This makes a difference on win64, where ``printf`` needs "%Id" to display
2285 64bit values.
2286
Benjamin Peterson97179b02008-09-09 20:55:01 +00002287- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2288 error.
2289
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002290- Issue #3777: long() applied to a float object now always return a long
2291 object; previously an int would be returned for small values. the __long__
2292 method is allowed to return either an int or a long, but the behaviour of
2293 float objects should not change to respect backward compatibility.
2294
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002295- Issue #3751: str.rpartition would perform a left-partition when called with
2296 a unicode argument.
2297
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002298- Issue #3683: Fix compilation when --without-threads is given.
2299
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002300- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002301 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002302 was correctly parsed but parsing of subsequent arguments failed.
2303
Vinay Sajip35e3b032008-09-01 14:33:59 +00002304- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002305 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2306 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2307 when given a tuple of classes as second argument, were looking up
2308 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2309 type object.
2310
Neal Norwitz18aa3882008-08-24 05:04:52 +00002311- Fix crashes on memory allocation failure found with failmalloc.
2312
2313- Fix memory leaks found with valgrind and update suppressions file.
2314
2315- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2316
2317- Fix problem using wrong name in decimal module reported by pychecker.
2318
Christian Heimes7d4c3172008-08-22 19:47:25 +00002319- Silenced another compiler warning about a used but not defined
2320 function 'stringlib_contains_obj'.
2321
Benjamin Peterson712ee922008-08-24 18:10:20 +00002322- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2323 ``__delslice__``.
2324
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002325- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2326 library targets in the Makefile.
2327
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002328- Issue #1204: The configure script now tests for additional libraries
2329 that may be required when linking against readline. This fixes issues
2330 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00002340- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
2341 stack usage in the case of deeply nested objects.
2342

Nick Coghland2e09382008-09-11 12:11:06 +00002347- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
2348 silent misbehaviour when a single instance is nested in multiple
2349 with statements, or when the methods are invoked in the wrong order.
2350

Nick Coghland2e09382008-09-11 12:11:06 +00002353- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002354 return a list or None rather than a custom object.
2355
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002356- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2380 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2381 for catch_warnings() also led to an improvement in the raising of a
2382 DeprecationWarning related to warnings.warn_explicit().
2383
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002384- The deprecation warnings for the old camelCase threading API were removed.

2409 without limit.
2410
Benjamin Peterson37346b22008-08-23 20:27:43 +00002411- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2412 exploitation of poor argument checking.
2413

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002448What's New in Python 2.6 beta 3?
2449================================
2450
Barry Warsaw07a4a382008-08-21 01:15:08 +00002451*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002452
2453Core and Builtins
2454-----------------
2455
Guido van Rossumf8402962008-08-20 15:01:50 +00002456- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2457 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2458 extensions do not automatically benefit from the class attribute
2459 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2460 to their tp_flags field if they care. This is a backwards
2461 compatibility feature; in 3.0, all types will use the cache by
2462 default.
2463
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002464- Keyword arguments can now follow starred arguments. (``f(a, *args,
2465 keyword=23)`` is now valid syntax.)
2466
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002467- ctypes function pointers that are COM methods have a boolean True
2468 value again.
2469
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002470- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2471 by denying s# to parse objects that have a releasebuffer procedure,
2472 and introducing s*.
2473
Georg Brandl1e13ea92008-08-11 09:07:59 +00002474- Issue #3537: Fix an assertion failure when an empty but presized dict
2475 object was stored in the freelist.
2476
Mark Dickinsonb6467572008-08-04 21:30:09 +00002477- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2478 ValueError consistently across platforms.
2479
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002480- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2481 (64bit Unix, for example), unichr() would truncate its argument and return
2482 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2483
Neal Norwitze7d8be82008-07-31 17:17:14 +00002484- Apply security patches from Apple.
2485
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002486- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2487 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2488
Antoine Pitrou92f82162008-07-25 22:22:08 +00002489- Issue #1819: function calls with several named parameters are now on
2490 average 35% faster (as measured by pybench).
2491
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002492- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2493 the python debugger steps into a class statement: the free variables (local
2494 variables defined in an outer scope) would be deleted from the outer scope.
2495
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002496- Issue #2620: Overflow checking when allocating or reallocating memory
2497 was not always being done properly in some python types and extension
2498 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2499 all been updated to perform better checks and places in the code that
2500 would previously leak memory on the error path when such an allocation
2501 failed have been fixed.

2505
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002506- Issue #3612: Added some missing basic types in ctypes.wintypes.
2507
Benjamin Petersone977ad42008-08-20 01:42:01 +00002508- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2509 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2510
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002511- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2512 version reported by these tools does not necessarily follow the python
2513 version numbering scheme, so the module is less strict when parsing it.
2514
Nick Coghlanf70385a2008-08-18 12:42:46 +00002515- Issue #2235: Added Py3k warnings for types which will become unhashable
2516 under the stricter __hash__ inheritance rules in 3.0. Several types
2517 which did not meet the rules for hash invariants and were already
2518 unhashable in 3.0 have now been explicitly flagged as unhashable in
2519 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2520 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2521
Brett Cannon88f801d2008-08-18 00:46:22 +00002522- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2523 imported into the module but exposed as part of the module's API.
2524
Brett Cannon7b96f072008-08-18 00:41:11 +00002525- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2526
Brett Cannon46225e72008-08-18 00:36:52 +00002527- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002529- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2530
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002531- Issue #3575: Incremental decoder's decode function now takes bytearray
2532 by using 's*' instead of 't#'.
2533
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002534- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002535 fails unicode conversion on 2nd parameter. (windows only)
2536
Facundo Batista94f243a2008-08-17 03:38:39 +00002537- Issue 2464. urllib2 now supports a malformation in the URL received
2538 in a redirect.
2539
Brett Cannonabe423e2008-08-16 21:47:07 +00002540- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002541 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002542
Facundo Batistaeb90b782008-08-16 14:44:07 +00002543- Issue #2776: fixed small issue when handling an URL with double slash
2544 after a 302 response in the case of not going through a proxy.
2545
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002546- Issue #2676: in the email package, content-type parsing was hanging on
2547 pathological input because of quadratic or exponential behaviour of a
2548 regular expression.
2549
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002550- Issue #3476: binary buffered reading through the new "io" library is now
2551 thread-safe.
2552
Brett Cannonbf3157b2008-08-14 05:00:03 +00002553- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2554 since mimetools itself is deprecated. Because modules are cached, all
2555 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2556
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002557- Issue #3134: shutil referenced undefined WindowsError symbol.
2558
Robert Schuppenies14646332008-08-10 11:01:53 +00002559- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2560 menu entries were not deleted.
2561
Brett Cannon83e81842008-08-09 23:30:55 +00002562- Copied the implementation of reduce() to _functools.reduce() to have a
2563 version that did not raise a DeprecationWarning under -3.
2564
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002565- Issue #3205: When iterating over a BZ2File fails allocating memory, raise

Benjamin Peterson01a24322008-07-28 23:35:27 +00002590- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002591 asking for a specific length. This problem only affected files opened
2592 using the new "io" module, not the built-in open() function.

2648-----------------
2649
Georg Brandl3e483f62008-07-16 22:57:41 +00002650- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2651 its methods now allow for items objects that can be converted to
2652 an integer using operator.index().
2653
Mark Dickinson64b7e502008-07-16 09:40:03 +00002654- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2655 produced a ValueError instead of giving the correct float.
2656
Eric Smitha5fa5a22008-07-16 00:11:49 +00002657- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2658 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2659
Mark Dickinson7103aa42008-07-15 19:08:33 +00002660- Issue #3008: the float type has a new instance method 'float.hex'
2661 and a new class method 'float.fromhex' to convert floating-point
2662 numbers to and from hexadecimal strings, respectively.
2663
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002664- Issue #2235: __hash__ is once again inherited by default. To allow
2665 collections.Hashable to remain meaningful in the presence of the
2666 default hash implementation (object.__hash__), it is now possible
2667 to explicit block inheritance of hash by setting __hash__=None at
2668 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2669 level.
2670
Nick Coghlanb028f502008-07-13 14:52:36 +00002671- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2672 the parent module cannot be found while performing an absolute import.
2673 This means that an incorrectly defined __package__ attribute will
2674 now only prevent relative imports in that module rather than causing
2675 all imports from that module to fail.
2676
Nick Coghlan14ff9942008-07-08 14:21:42 +00002677- Issue #2517: Allow unicode messages in Exceptions again by correctly

2687 another thread's dictionary.
2688
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002689- Issue #3004: Minor change to slice.indices(): the start and stop
2690 arguments are now treated identically, making the behaviour easier
2691 to describe and understand. For example, slice(None, -10,
2692 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2693 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2694 10, -1).
2695
Georg Brandl278fc502008-07-19 12:46:12 +00002696- Issue #3219: Calling a function with repeated keyword arguments,
2697 f(a=2, a=23), would not cause a syntax error. This was a regression
2698 from 2.4 caused by the switch to the new compiler.

2708 api functions without holding the GIL, which could lead to a fatal
2709 error when they failed.
2710
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002711- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002736- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2737 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002738 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002739 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002755- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3143
Brett Cannonb61d8012008-05-11 23:39:04 +00003144- ``Lib/lib-old`` is now added to sys.path.
3145
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003146- On MacOS X it is now possible to install the framework in 64-bit
3147 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003148 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003149
3150 This is controlled by the configure argument ``--with-universal-archs``:
3151
3152 - ``--with-universal-archs=all``: install 4-way universal
3153
3154 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3155
3156 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3157
3158 This option should be used in combination with ``--enable-universalsdk=``.
3159
3160 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00003169
3170- The PyString functions have been renamed to PyBytes. A batch of
3171 defines were added so that the linker still sees the original
3172 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003210- Issue #1631171: Re-implement the 'warnings' module in C (the
3211 original Python code has been kept as backup). This will allow for
3212 using the 'warning's machinery in such places as the parser where
3213 use of pure Python code is not possible. Both the ``showarning()``
3214 and ``formatwarning()`` gain an optional 'line' argument which is
3215 not called by default for backwards-compatibility reasons. Setting
3216 ``warnings.showwarning()`` to an implementation that lacks support
3217 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003242- The getpass module has been improved on Unix. It now uses /dev/tty
3243 by default and uses stderr instead of stdout. A GetPassWarning is
3244 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003259- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003260 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003280- Issue #2550: The approach used by client/server code for obtaining
3281 ports to listen on in network-oriented tests has been refined in an
3282 effort to facilitate running multiple instances of the entire
3283 regression test suite in parallel without issue.
3284 test_support.bind_port() has been fixed such that it will always
3285 return a unique port -- which wasn't always the case with the
3286 previous implementation, especially if socket options had been set
3287 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3288 new implementation of bind_port() will actually raise an exception
3289 if it is passed an AF_INET/SOCK_STREAM socket with either the
3290 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3291 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3292 the socket it's been passed. This currently only applies to
3293 Windows. This option prevents any other sockets from binding to the
3294 host/port we've bound to, thus removing the possibility of the
3295 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3296 when a second SOCK_STREAM socket binds and accepts to a host/port
3297 that's already been bound by another socket. The optional preferred
3298 port parameter to bind_port() has been removed. Under no
3299 circumstances should tests be hard coding ports!
3300
3301 test_support.find_unused_port() has also been introduced, which will
3302 pass a temporary socket object to bind_port() in order to obtain an
3303 unused port. The temporary socket object is then closed and
3304 deleted, and the port is returned. This method should only be used
3305 for obtaining an unused port in order to pass to an external program
3306 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3307 a parameter to a server-oriented class that doesn't give you direct
3308 access to the underlying socket used.
3309
3310 Finally, test_support.HOST has been introduced, which should be used
3311 for the host argument of any relevant socket calls (i.e. bind and
3312 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003313
3314 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003315 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003316 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3317 test_asynchat and test_socket_ssl.
3318
Georg Brandl3ee81df2008-05-17 18:14:43 +00003319 It is now possible for multiple instances of the regression test
3320 suite to run in parallel without issue.

3587-----------------
3588
Fred Drakea8ee94b2008-03-01 02:45:07 +00003589- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003590 644. The mode is now inherited from the py file.

3593
3594- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003595
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003596- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003597 issue 215555 for a discussion.
3598
Eric Smitha73fbe72008-02-23 03:09:44 +00003599- Added the future_builtins module, which contains hex() and oct().
3600 These are the PEP 3127 version of these functions, designed to be
3601 compatible with the hex() and oct() builtins from Python 3.0. They
3602 differ slightly in their output formats from the existing, unchanged
3603 Python 2.6 builtins. The expected usage of the future_builtins
3604 module is:
3605 from future_builtins import hex, oct
3606
Eric Smith7ef40bf2008-02-20 23:34:22 +00003607- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3608 exponents for exponents with absolute value < 100. Follows C99
3609 standard. This is a change on Windows, which would use 3 digits.
3610 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3611 so that any alterations it does to the resulting string will be
3612 available in stringlib/formatter.h (for float.__format__).
3613
Eric Smith5a3c1352008-02-19 13:21:56 +00003614- Implemented PEP 3101, Advanced String Formatting. This adds a new
3615 builtin format(); a format() method for str and unicode; a
3616 __format__() method to object, str, unicode, int, long, float, and
3617 datetime; the class string.Formatter; and the C API
3618 PyObject_Format().
3619
Georg Brandl3ee81df2008-05-17 18:14:43 +00003620- Fixed several potential crashes, all caused by specially crafted
3621 __del__ methods exploiting objects in temporarily inconsistent
3622 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003623
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003624- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003625 prevent a possible crash: an Abstract Base Class would try to access
3626 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003627

Georg Brandl3ee81df2008-05-17 18:14:43 +00003631- Clear all free lists during a gc.collect() of the highest generation
3632 in order to allow pymalloc to free more arenas. Python may give back
3633 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003634
Georg Brandl3ee81df2008-05-17 18:14:43 +00003635- Issue #2045: Fix an infinite recursion triggered when printing a
3636 subclass of collections.defaultdict, if its default_factory is set
3637 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003638
Christian Heimesf75dbef2008-02-08 00:11:31 +00003639- Fixed a minor memory leak in dictobject.c. The content of the free
3640 list was not freed on interpreter shutdown.
3641
Georg Brandl3ee81df2008-05-17 18:14:43 +00003642- Limit free list of method and builtin function objects to 256
3643 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003644
Georg Brandl3ee81df2008-05-17 18:14:43 +00003645- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3646 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003647 to compact the internal free lists of pre-allocted ints and floats.
3648
Georg Brandl3ee81df2008-05-17 18:14:43 +00003649- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3650 calls. Python expected the return type int but the fork familie
3651 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003652
Georg Brandl3ee81df2008-05-17 18:14:43 +00003653- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3660 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003661
Georg Brandl3ee81df2008-05-17 18:14:43 +00003662- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3663 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003664
Georg Brandl3ee81df2008-05-17 18:14:43 +00003665- Patch #1473257: generator objects gain a gi_code attribute. This is
3666 the same object as the func_code attribute of the function that
3667 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003668
Georg Brandl3ee81df2008-05-17 18:14:43 +00003669- Issue #1920: "while 0" statements were completely removed by the
3670 compiler, even in the presence of an "else" clause, which is
3671 supposed to be run when the condition is false. Now the compiler
3672 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003673
Guido van Rossumeead05f2008-01-24 18:21:02 +00003674- A few crashers fixed: weakref_in_del.py (issue #1377858);
3675 loosing_dict_ref.py (issue #1303614, test67.py);
3676 borrowed_ref_[34].py (not in tracker).
3677
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003678- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003679 suppressed while an extension is loaded by calling SetErrorMode in
3680 dynload_win.c. The error is still reported properly.
3681
Georg Brandl3ee81df2008-05-17 18:14:43 +00003682- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003683 several extension methods and modules do not work without unicode
3684 support.
3685
Georg Brandl26543b12008-01-21 18:36:51 +00003686- Issue #1882: when compiling code from a string, encoding cookies in the
3687 second line of code were not always recognized correctly.
3688
Georg Brandl14404b62008-01-19 19:27:05 +00003689- Issue #1679: "0x" was taken as a valid integer literal.
3690
Georg Brandl6caad7d2008-01-26 14:19:22 +00003691- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003692 added.
3693
Christian Heimesc94e2b52008-01-14 04:13:37 +00003694- sys.float_info / PyFloat_GetInfo: The floating point information
3695 object was converted from a dict to a specialized structseq object.
3696
Georg Brandl3ee81df2008-05-17 18:14:43 +00003697- Patch #1816: Added sys.flags structseq. It exposes the status of
3698 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003699
Georg Brandl3ee81df2008-05-17 18:14:43 +00003700- Objects/structseq.c: Implemented new structseq representation. The
3701 patch makes structseqs (e.g. the return value of os.stat) more
3702 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003703
Georg Brandl3ee81df2008-05-17 18:14:43 +00003704- Patch #1700288: added a type attribute cache that caches method
3705 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003706
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003707- Bug #1776: __import__() no longer accepts filenames on any platform.
3708 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003709
Georg Brandlaed6c662008-01-07 17:25:53 +00003710- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3711
Georg Brandl3ee81df2008-05-17 18:14:43 +00003712- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3713 envvar and sys.dont_write_bytecode attribute. All these can be set
3714 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003715
Georg Brandl3ee81df2008-05-17 18:14:43 +00003716- Improve some exception messages when Windows fails to load an
3717 extension module. Now we get for example '%1 is not a valid Win32
3718 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003719

Christian Heimes0a8143f2007-12-18 23:22:54 +00003725- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726 and INF. float("nan"), float("inf") and float("-inf") now work on
3727 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003728
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Compiler now generates simpler and faster code for dictionary
3730 literals. The oparg for BUILD_MAP now indicates an estimated
3731 dictionary size. There is a new opcode, STORE_MAP, for adding
3732 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003761- Patch #1739468: Directories and zipfiles containing a __main__.py
3762 file can now be directly executed by passing their name to the
3763 interpreter. The directory/zipfile is automatically inserted as the
3764 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Issue #1265: Fix a problem with sys.settrace, if the tracing
3767 function uses a generator expression when at the same time the
3768 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003769
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003770- sets and frozensets now have an isdisjoint() method.
3771

3773
Neal Norwitz44f326e2007-10-05 05:29:17 +00003774- Fix warnings found by the new version of the Coverity checker.
3775
Georg Brandl3ee81df2008-05-17 18:14:43 +00003776- The enumerate() builtin function is no longer bounded to sequences
3777 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3778 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003779
Georg Brandl3ee81df2008-05-17 18:14:43 +00003780- Issue #1686386: Tuple's tp_repr did not take into account the
3781 possibility of having a self-referential tuple, which is possible
3782 from C code. Nor did object's tp_str consider that a type's tp_str
3783 could do something that could lead to an inifinite recursion.
3784 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3785 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003786
Georg Brandl3ee81df2008-05-17 18:14:43 +00003787- Issue #1164: It was possible to trigger deadlock when using the
3788 'print' statement to write to a file since the GIL was not released
3789 as needed. Now PyObject_Print() does the right thing along with
3790 various tp_print implementations of the built-in types and those in
3791 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003792
Georg Brandl3ee81df2008-05-17 18:14:43 +00003793- Issue #1147: Exceptions were directly allowing string exceptions in
3794 their throw() method even though string exceptions no longer
3795 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003796
Georg Brandl3ee81df2008-05-17 18:14:43 +00003797- Issue #1096: Prevent a segfault from getting the repr of a very
3798 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003799
Brett Cannon1e534b52007-09-07 04:18:30 +00003800- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003801 PyObject_Call() never calling back out to Python code to trigger
3802 recursion depth updates/checks. Required the creation of a static
3803 RuntimeError instance in case normalizing an exception put the
3804 recursion check value past its limit. Fixes crashers
3805 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003806
Georg Brandl3ee81df2008-05-17 18:14:43 +00003807- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003820- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821 __*__ attributes. (Some already existed, e.g., __doc__ and
3822 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003823
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003824- Add -3 option to the interpreter to warn about features that are
3825 deprecated and will be changed/removed in Python 3.0.
3826
Georg Brandl2134e752007-05-21 20:34:16 +00003827- Patch #1686487: you can now pass any mapping after '**' in function
3828 calls.
3829
Collin Winter62903052007-05-18 23:11:24 +00003830- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003831 "except E as target:". This is to provide forwards compatibility
3832 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003833
Brett Cannon229cee22007-05-05 01:34:02 +00003834- Deprecate BaseException.message as per PEP 352.
3835
Georg Brandl3ee81df2008-05-17 18:14:43 +00003836- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003837 inherited from a builtin base.
3838
Vinay Sajip8549ce32007-05-06 17:53:37 +00003839- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003840 setting a plain string, ie don't expand to single letter identifiers.
3841
Raymond Hettinger13936692007-04-11 18:40:58 +00003842- Request #1191699: Slices can now be pickled.
3843
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003844- Request #1193128: str.translate() now allows a None argument for
3845 translations that only remove characters without re-mapping the
3846 remaining characters.
3847
Georg Brandl5cb76c12007-03-21 09:00:39 +00003848- Patch #1682205: a TypeError while unpacking an iterable is no longer
3849 masked by a generic one with the message "unpack non-sequence".
3850
Neal Norwitzaa754b72007-03-21 06:39:48 +00003851- Remove unused file Python/fmod.c.
3852
Guido van Rossum143b5642007-03-23 04:58:42 +00003853- Bug #1683368: The object.__init__() and object.__new__() methods are
3854 now stricter in rejecting excess arguments. The only time when
3855 either allows excess arguments is when it is not overridden and the
3856 other one is. For backwards compatibility, when both are
3857 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003858 warning later). Also, type.__init__() insists on the same signature
3859 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003860
Georg Brandl3ee81df2008-05-17 18:14:43 +00003861- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3862 object to complex using its __complex__() method before falling back
3863 to the __float__() method. Therefore, the functions in the cmath
3864 module now can operate on objects that define a __complex__()
3865 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- Patch #1623563: allow __class__ assignment for classes with
3868 __slots__. The old and the new class are still required to have the
3869 same slot names.

3875 ``object.__reduce_ex__()`` is called with an object that is faking
3876 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003877
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878- Patch #1680015: Don't modify __slots__ tuple if it contains an

3882
Georg Brandl7b9c5552007-03-12 14:30:05 +00003883- Bug #1678647: write a newline after printing an exception in any
3884 case, even when converting the value to a string failed.
3885
Georg Brandl871f1bc2007-03-12 13:17:36 +00003886- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003887 its argument, if it exists. If not, it will work like before. This
3888 allows customizing the output of dir() in the presence of a
3889 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003891- Patch #922167: Python no longer segfaults when faced with infinitely
3892 self-recursive reload() calls (as reported by bug #742342).
3893
Georg Brandl3ee81df2008-05-17 18:14:43 +00003894- Patch #1675981: remove unreachable code from ``type.__new__()``

Facundo Batistad918a652007-04-24 13:54:38 +00004412- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004413 the client's request was successfully received, understood, and
4414 accepted. Now in these cases no error is raised in urllib (issue
4415 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004416

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004423- Added a timeout parameter to the constructor of other protocols
4424 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4425 work started with create_connection() and timeout in httplib, and
4426 closes patch #723312.
4427
Vinay Sajip8549ce32007-05-06 17:53:37 +00004428- Patch #1676823: Added create_connection() to socket.py, which may be
4429 called with a timeout, and use it from httplib (whose HTTPConnection

Facundo Batista07c78be2007-03-23 18:54:07 +00004431
Martin v. Löwis0af33882007-03-23 13:27:15 +00004432- Bug #978833: Revert r50844, as it broke _socketobject.dup.

4452
Georg Brandlf66b6032007-03-14 08:27:52 +00004453- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004454 AttributeError instead of an IOError when the server's response
4455 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004456
Georg Brandl3ee81df2008-05-17 18:14:43 +00004457- Patch #957650: "%var%" environment variable references are now
4458 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00004461- Patch #1429539: pdb now correctly initializes the __main__ module
4462 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004463 correctly now.
4464
Georg Brandlbad6f192007-03-13 21:32:56 +00004465- The nonobvious commands.getstatus() function is now deprecated.

4471
Georg Brandl3ee81df2008-05-17 18:14:43 +00004472- Patch #1530482: add pydoc.render_doc() which returns the
4473 documentation for a thing instead of paging it to stdout, which
4474 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004475

Georg Brandl9e6b4702007-03-13 18:15:41 +00004485- Patch #1581073: add a flag to textwrap that prevents the dropping of

4487
Georg Brandl92a6bae2007-03-13 17:43:32 +00004488- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004489 are set for invalid interpolation sequences that would lead to
4490 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004491

4504
Georg Brandl94fe3f52007-03-13 09:32:11 +00004505- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00004506 field names in its exception message if you try to write a record
4507 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004525

4533 returned string up to the first NUL character.

4544
Georg Brandl3ee81df2008-05-17 18:14:43 +00004545- unittest now verifies more of its assumptions. In particular,
4546 TestCase and TestSuite subclasses (not instances) are no longer
4547 accepted in TestSuite.addTest(). This should cause no
4548 incompatibility since it never made sense with ordinary subclasses
4549 -- the failure just occurred later, with a more cumbersome
4550 exception.

4560
Georg Brandl3ee81df2008-05-17 18:14:43 +00004561- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004939 time so that opening a database previously created with the DB_DUP
4940 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4941 opens. Specifically: dictionary assignment to a DB object will
4942 replace all values for a given key when the database allows
4943 duplicate values. DB users should use DB.put(k, v) when they want
4944 to store duplicates; not DB[k] = v.

4951 characters with ASCII value less than 32. Also, it correctly quotes
4952 dots only if they occur on a single line, as opposed to the previous
4953 behavior of quoting dots if they are the second character of any
4954 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004955
