39 exception of canonical and is_canonical) now accept instances of int
40 and long wherever a Decimal instance is accepted, and implicitly
41 convert that argument to Decimal. Previously only some arguments

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

112
Antoine Pitroue80a6a42010-01-17 12:26:20 +0000113- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
114 could crash in many places because of the PyByteArray_AS_STRING() macro
115 returning NULL. The macro now returns a statically allocated empty
116 string instead.

125 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +0000126 strings corresponding to subnormal values, (3) a memory leak for
127 some values large enough to cause overflow, and (4) a number of
128 flaws that could lead to incorrectly rounded results.

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

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

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

183 the release file is empty.
184
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000185- Issue #7748: Since unicode values are supported for some metadata options
186 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
187 encoded string for them. This ensure that the upload and register commands
188 send the right values to PyPI without any error.
189
R. David Murrayed44dfa2010-01-16 05:15:17 +0000190- Issue #1670765: Prevent email.generator.Generator from re-wrapping

Benjamin Petersonecdae192010-01-04 00:43:01 +0000268- The __complex__ method is now looked up on the class of instances to make it
269 consistent with other special methods.
270
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000271- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

273
Mark Dickinson1b34d252010-01-01 17:27:30 +0000274- Issue #5080: A number of functions and methods previously produced a
275 DeprecationWarning when passed a float argument where an integer was
276 expected. These functions and methods now raise TypeError instead.
277 The majority of the effects of this change are in the extension
278 modules, but some core functions and methods are affected: notably
279 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
280 methods.
281
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000282- Issue #7604: Deleting an unset slotted attribute did not raise an

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000289- Issue #7579: the msvcrt module now has docstrings for all its functions.
290
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000291- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
292 used to drop the time part of the result.
293
Mark Dickinson46572832009-12-27 14:55:57 +0000294- Issue #1811: improve accuracy and cross-platform consistency for
295 true division of integers: the result of a/b is now correctly
296 rounded for ints a and b (at least on IEEE 754 platforms), and in
297 particular does not depend on the internal representation of a long.
298
Ezio Melottif84caf42009-12-24 22:25:17 +0000299- Issue #6108: unicode(exception) and str(exception) should return the same

301
Ronald Oussoren92919a62009-12-24 13:30:58 +0000302- Issue #6834: replace the implementation for the 'python' and 'pythonw'

446
Eric Smithc4ab8332009-11-29 17:40:57 +0000447- Issue #3382: 'F' formatting for float and complex now convert the
448 result to upper case. This only affects 'inf' and 'nan', since 'f'
449 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000450

455 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
456 requested 120 significant digits instead.

463 on MacOSX 10.6.
464
Mark Dickinsonb678de82009-11-19 18:41:49 +0000465- Issue #7117: repr(x) for a float x returns a result based on the
466 shortest decimal string that's guaranteed to round back to x under
467 correct rounding (with round-half-to-even rounding mode).
468 Previously it gave a string based on rounding x to 17 decimal digits.
469 repr(x) for a complex number behaves similarly. On platforms where
470 the correctly-rounded strtod and dtoa code is not supported (see below),
471 repr is unchanged.
472
473- Issue #7117: On almost all platforms: float-to-string and
474 string-to-float conversions within Python are now correctly rounded.
475 Places these conversions occur include: str for floats and complex
476 numbers; the float and complex constructors; old-style and new-style
477 numeric formatting; serialization and deserialization of floats and
478 complex numbers using marshal, pickle and json; parsing of float and
479 imaginary literals in Python code; Decimal-to-float conversion.
480
481 The conversions use a Python-adapted version of David Gay's
482 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
483 functions. This code is supported on Windows, and on Unix-like
484 platforms using gcc, icc or suncc as the C compiler. There may be a
485 small number of platforms on which correct operation of this code
486 cannot be guaranteed, so the code is not used: notably, this applies
487 to platforms where the C double format is not IEEE 754 binary64, and
488 to platforms on x86 hardware where the x87 FPU is set to 64-bit
489 precision and Python's configure script is unable to determine how
490 to change the FPU precision. On these platforms conversions use the
491 platform strtod and dtoa, as before.
492
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000493- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000494 now uses the correctly-rounded string <-> float conversions
495 described above (when available), and so produces correctly rounded
496 results that will display nicely under the float repr. There are
497 two related small changes: (1) round now accepts any class with an
498 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000499 floats for the second argument), and (2) an excessively large second
500 integer argument (e.g., round(1.234, 10**100)) no longer raises an
501 exception.

618 possible to update the lineno attribute of the current frame.
619
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000620- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000621 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000622
Raymond Hettinger578a2282009-05-29 04:58:52 +0000623- Issue #5982: staticmethod and classmethod now expose the wrapped
624 function with __func__.
625
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000626- Added support for multiple context managers in the same with-statement.
627 Deprecated contextlib.nested() which is no longer needed.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000629- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
630 statement and correctly lookup the __enter__ and __exit__ special methods.
631
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000632- Issue #5829: complex("1e500") no longer raises OverflowError. This
633 makes it consistent with float("1e500") and interpretation of real
634 and imaginary literals.
635
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000636- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
637
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000638- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
639 classes and instances.

R. David Murray525cffc2009-05-13 13:07:14 +0000641- Issue #5994: the marshal module now has docstrings.
642
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000643- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
644 (1) inf and nan strings with trailing whitespace were incorrectly
645 rejected; (2) parsing of strings representing infinities and nans
646 was locale aware; and (3) the interpretation of fromhex('-nan')
647 didn't match that of float('-nan').
648
Eric Smitha985a3a2009-05-05 18:26:08 +0000649- Issue #5920: For float.__format__, change the behavior with the
650 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
651 to be like 'g' but with at least one decimal point and with a
652 default precision of 12. Previously, the behavior the same but with
653 a default precision of 6. This more closely matches str(), and
654 reduces surprises when adding alignment flags to the empty
655 presentation type. This also affects the new complex.__format__ in
656 the same way.
657
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000658- Issue #5890: in subclasses of 'property' the __doc__ attribute was
659 shadowed by classtype's, even if it was None. property now
660 inserts the __doc__ into the subclass instance __dict__.
661
Antoine Pitrou653dece2009-05-04 18:32:32 +0000662- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
663 sequences. Patch by Nick Barnes and Victor Stinner.
664
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000665- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000666 format(complex(1, 2./3), '.5') now produces a sensible result.
667

675 titlecase, but not their own uppercase.
676
Eric Smith068f0652009-04-25 21:40:15 +0000677- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
678 _PyOS_double_to_string or PyOS_double_to_string.
679
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000680- Issue #5283: Setting __class__ in __del__ caused a segfault.
681
Mark Dickinson95bc9802009-04-24 12:46:53 +0000682- Issue #5816: complex(repr(z)) now recovers z exactly, even when
683 z involves nans, infs or negative zeros.
684
Eric Smithaca19e62009-04-22 13:29:05 +0000685- Implement PEP 378, Format Specifier for Thousands Separator, for
686 floats, ints, and longs.
687
688- Issue #5515: 'n' formatting for ints, longs, and floats handles
689 leading zero formatting poorly.
690
691- Issue #5772: For float.__format__, don't add a trailing ".0" if
692 we're using no type code and we have an exponent.
693

698 some builtin types.
699
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000700- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000701 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000702
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000703- Issue #5759: float() didn't call __float__ on str subclasses.
704
Georg Brandl3c4a5462009-04-12 12:08:12 +0000705- Issue #5704: the "-3" command-line option now implies "-t".
706
R. David Murray0374a822009-04-09 21:54:50 +0000707- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
708 its clarity and its speed.
709

Ronald Oussorene0154ed2009-03-30 23:10:35 +0000717- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
718 the end sys.path, for compatibility with the system install of Python.
719
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000720- Issue #4688: Add a heuristic so that tuples and dicts containing only
721 untrackable objects are not tracked by the garbage collector. This can
722 reduce the size of collections and therefore the garbage collection overhead
723 on long-running programs, depending on their particular use of datatypes.
724
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000725- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
726 improve its performance. Long divisions and remainder operations
727 are now between 50% and 150% faster.
728
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000729- Issue #4258: Make it possible to use base 2**30 instead of base
730 2**15 for the internal representation of integers, for performance
731 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
732 --enable-big-digits option to configure, which overrides the
733 default. Add sys.long_info structseq to provide information about
734 the internal format.
735
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000736- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
737 result traceback.__members__ no longer exists.)
738
Mark Dickinson6b265f12009-03-18 16:07:26 +0000739- Issue #4474: PyUnicode_FromWideChar now converts characters outside
740 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
741 and sizeof(Py_UNICODE) == 2.
742
Eric Smith6f42edb2009-03-14 11:57:26 +0000743- Issue #5237: Allow auto-numbered fields in str.format(). For
744 example: '{} {}'.format(1, 2) == '1 2'.
745
Brett Cannon6c4cff02009-03-11 04:51:06 +0000746- Issue #3652: Make the 'line' argument for warnings.showwarning() a
747 requirement. Means the DeprecationWarning from Python 2.6 can go away.
748
Eric Smithe9fb6862009-02-20 14:02:36 +0000749- Issue #5247: Improve error message when unknown format codes are
750 used when using str.format() with str, unicode, long, int, and
751 float arguments.
752
Raymond Hettinger08259e82009-02-18 23:10:19 +0000753- Running Python with the -3 option now also warns about classic division
754 for ints and longs.
755
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000756- Issue #5260: Long integers now consume less memory: average
757 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
758 on a 64-bit system.
759
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000760- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
761 rotating the object pointer by 4 bits to the right.
762
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000763- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
764 it now forces its argument to double before testing for infinity.
765
Benjamin Petersone18ef192009-01-20 14:21:16 +0000766- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
767
Georg Brandl29c6a282009-04-05 20:23:13 +0000768- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000769 were suppressing all exceptions. These include list(), filter(), map(),
770 zip(), and bytearray().
771
Benjamin Peterson596d3062009-01-19 15:42:23 +0000772- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
773 functions.
774
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000775- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

779
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000780- Issue #4935: The overflow checking code in the expandtabs() method common
781 to str, bytes and bytearray could be optimized away by the compiler, letting
782 the interpreter segfault instead of raising an error.
783
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000784- Issue #3720: Fix a crash when an iterator modifies its class and removes its

790
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000791- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
792 collecting the oldest generation) so that allocating lots of objects without
793 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000794 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000795 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

798
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000799- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
800 an existing .py counterpart, override the co_filename attributes of all
801 code objects if the original filename is obsolete (which can happen if the
802 file has been renamed, moved, or if it is accessed through different paths).
803 Patch by Ziga Seilnacht and Jean-Paul Calderone.
804
Martin v. Löwis5344c992009-01-02 20:32:55 +0000805- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000807- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
808 file with `str' filename on Windows.
809
Antoine Pitrouaa687902009-01-01 14:11:22 +0000810- Issue #3680: Reference cycles created through a dict, set or deque iterator
811 did not get collected.
812
Nick Coghlan180e4002008-12-30 01:18:48 +0000813- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
814 where the tp_hash and tp_dict slots are both NULL.
815
Benjamin Peterson7af65562008-12-29 17:56:58 +0000816- Issue #4764: With io.open, IOError.filename is set when trying to open a
817 directory on POSIX systems.
818
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000819- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

826 fail.
827
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000828- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
829 print elapsed times, not only when some objects are uncollectable /
830 unreachable. Original patch by Neil Schemenauer.
831
Mark Dickinson1a707982008-12-17 16:14:37 +0000832- Issue #3439: Add a bit_length method to int and long.

838 context manager returns a value that cannot be converted to a bool.
839
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000840- Issue #4597: Fixed several opcodes that weren't always propagating
841 exceptions.
842
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000843- Issue #4445: Replace "sizeof(PyStringObject)" with
844 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
845 str instances. On a typical machine this saves 3 bytes of memory
846 (on average) per string allocation.
847
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000848- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
849 interpreter to abort ("Fatal Python error: Could not reset the stack!")
850 instead of throwing a MemoryError.
851
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000852- Issue #3689: The list reversed iterator now supports __length_hint__

857
Vinay Sajip213faca2008-12-03 23:22:58 +0000858- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000859 method on file objects with closefd=False. The file descriptor is still
860 kept open but the file object behaves like a closed file. The ``FileIO``
861 object also got a new readonly attribute ``closefd``.
862
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000863- Issue #4348: Some bytearray methods returned that didn't cause any change to
864 the bytearray, returned the same bytearray instead of a copy.
865

874
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000875- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
876 method does not return iterators for the 4th and 5th items.
877
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000878- Issue #4209: Enabling unicode_literals and the print_function in the same
879 __future__ import didn't work.
880
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000881- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000882 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000883
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000884- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
885 returned a path longer than MAX_PATH. (But It's doubtful this code path is
886 really executed because I cannot move to such directory on win2k)
887
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000888- Issue #4069: When set.remove(element) is used with a set element, the element
889 is temporarily replaced with an equivalent frozenset. But the eventual
890 KeyError would always report the empty frozenset([]) as the missing key. Now
891 it correctly refers to the initial element.
892
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000893- Issue #4509: Various issues surrounding resize of bytearray objects to

Walter Dörwalded960ac2009-05-03 22:36:33 +0000911- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
912 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
913 step. This avoids problems with counting UTF-8 bytes that ignores the effect
914 of using the replace error handler in PyUnicode_DecodeUTF8().
915
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000916- Issue #3739: The unicode-internal encoder now reports the number of characters

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

Antoine Pitrou59c44f32009-10-30 17:07:08 +00002158- Issue #7222: Make thread "reaping" more reliable so that reference
2159 leak-chasing test runs give sensible results. The previous method of
2160 reaping threads could return successfully while some Thread objects were
2161 still referenced. This also introduces a new private function:
2162 :func:`thread._count()`.
2163
R. David Murray282396f2009-10-18 21:12:37 +00002164- Issue #7151: fixed regrtest -j so that output to stderr from a test no

2180 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

2182 skip the tests if DISPLAY is defined but can't be used.
2183
Antoine Pitrou4698d992009-05-31 14:20:14 +00002184- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

2188 it easy to import both normal and optimised versions of modules.
2189 test_heapq and test_warnings have been adjusted to use it, tests for
2190 other modules with both C and Python implementations in the stdlib
2191 can be adjusted to use it over time.

Vinay Sajip22aa4bb2009-04-16 19:15:49 +00002200 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00002201 from test support, which does the conversion.

Georg Brandl2bd92a52009-10-11 21:10:07 +00002282- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00002283 AttributeError instead of RuntimeError, depending in which C API call
2284 exactly the recursion limit is exceeded. Consequently, both exception types
2285 are caught and silenced.

2300-----------------
2301
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002302- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2303
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002304- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2305 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2306 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2307 ``printf`` function, whereas PyString_FromFormat has an independent
2308 implementation and uses "%zd" on all platforms for size_t values.
2309 This makes a difference on win64, where ``printf`` needs "%Id" to display
2310 64bit values.
2311
Benjamin Peterson97179b02008-09-09 20:55:01 +00002312- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2313 error.
2314
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002315- Issue #3777: long() applied to a float object now always return a long
2316 object; previously an int would be returned for small values. the __long__
2317 method is allowed to return either an int or a long, but the behaviour of
2318 float objects should not change to respect backward compatibility.
2319
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002320- Issue #3751: str.rpartition would perform a left-partition when called with
2321 a unicode argument.
2322
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002323- Issue #3683: Fix compilation when --without-threads is given.
2324
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002325- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002326 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002327 was correctly parsed but parsing of subsequent arguments failed.
2328
Vinay Sajip35e3b032008-09-01 14:33:59 +00002329- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002330 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2331 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2332 when given a tuple of classes as second argument, were looking up
2333 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2334 type object.
2335
Neal Norwitz18aa3882008-08-24 05:04:52 +00002336- Fix crashes on memory allocation failure found with failmalloc.
2337
2338- Fix memory leaks found with valgrind and update suppressions file.
2339
2340- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2341
2342- Fix problem using wrong name in decimal module reported by pychecker.
2343
Christian Heimes7d4c3172008-08-22 19:47:25 +00002344- Silenced another compiler warning about a used but not defined
2345 function 'stringlib_contains_obj'.

2348 ``__delslice__``.
2349
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002350- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2351 library targets in the Makefile.
2352
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002353- Issue #1204: The configure script now tests for additional libraries
2354 that may be required when linking against readline. This fixes issues
2355 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

2366 stack usage in the case of deeply nested objects.
2367

2377
Nick Coghland2e09382008-09-11 12:11:06 +00002378- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002379 return a list or None rather than a custom object.
2380
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002381- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2405 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2406 for catch_warnings() also led to an improvement in the raising of a
2407 DeprecationWarning related to warnings.warn_explicit().
2408
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002409- The deprecation warnings for the old camelCase threading API were removed.

2478Core and Builtins
2479-----------------
2480
Guido van Rossumf8402962008-08-20 15:01:50 +00002481- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2482 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2483 extensions do not automatically benefit from the class attribute
2484 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2485 to their tp_flags field if they care. This is a backwards
2486 compatibility feature; in 3.0, all types will use the cache by
2487 default.
2488
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002489- Keyword arguments can now follow starred arguments. (``f(a, *args,
2490 keyword=23)`` is now valid syntax.)
2491
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002492- ctypes function pointers that are COM methods have a boolean True
2493 value again.
2494
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002495- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2496 by denying s# to parse objects that have a releasebuffer procedure,
2497 and introducing s*.
2498
Georg Brandl1e13ea92008-08-11 09:07:59 +00002499- Issue #3537: Fix an assertion failure when an empty but presized dict
2500 object was stored in the freelist.
2501
Mark Dickinsonb6467572008-08-04 21:30:09 +00002502- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2503 ValueError consistently across platforms.
2504
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002505- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2506 (64bit Unix, for example), unichr() would truncate its argument and return
2507 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2508
Neal Norwitze7d8be82008-07-31 17:17:14 +00002509- Apply security patches from Apple.
2510
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002511- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2512 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2513
Antoine Pitrou92f82162008-07-25 22:22:08 +00002514- Issue #1819: function calls with several named parameters are now on
2515 average 35% faster (as measured by pybench).
2516
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002517- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2518 the python debugger steps into a class statement: the free variables (local
2519 variables defined in an outer scope) would be deleted from the outer scope.
2520
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002521- Issue #2620: Overflow checking when allocating or reallocating memory
2522 was not always being done properly in some python types and extension
2523 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2524 all been updated to perform better checks and places in the code that
2525 would previously leak memory on the error path when such an allocation
2526 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002531- Issue #3612: Added some missing basic types in ctypes.wintypes.
2532
Benjamin Petersone977ad42008-08-20 01:42:01 +00002533- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2534 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2535
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002536- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2537 version reported by these tools does not necessarily follow the python
2538 version numbering scheme, so the module is less strict when parsing it.
2539
Nick Coghlanf70385a2008-08-18 12:42:46 +00002540- Issue #2235: Added Py3k warnings for types which will become unhashable
2541 under the stricter __hash__ inheritance rules in 3.0. Several types
2542 which did not meet the rules for hash invariants and were already
2543 unhashable in 3.0 have now been explicitly flagged as unhashable in
2544 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2545 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2546
Brett Cannon88f801d2008-08-18 00:46:22 +00002547- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2548 imported into the module but exposed as part of the module's API.
2549
Brett Cannon7b96f072008-08-18 00:41:11 +00002550- Remove an unneeded import of abc.ABCMeta from 'inspect'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002554- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2555
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002556- Issue #3575: Incremental decoder's decode function now takes bytearray
2557 by using 's*' instead of 't#'.
2558
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002559- Issue #2222: Fixed reference leak when occurred os.rename()

Antoine Pitroude781a42008-08-09 12:43:23 +00002616 asking for a specific length. This problem only affected files opened

2660
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002661- Issue #643841: The language reference now provides more detailed

2673-----------------
2674
Georg Brandl3e483f62008-07-16 22:57:41 +00002675- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2676 its methods now allow for items objects that can be converted to
2677 an integer using operator.index().
2678
Mark Dickinson64b7e502008-07-16 09:40:03 +00002679- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2680 produced a ValueError instead of giving the correct float.
2681
Eric Smitha5fa5a22008-07-16 00:11:49 +00002682- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2683 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2684
Mark Dickinson7103aa42008-07-15 19:08:33 +00002685- Issue #3008: the float type has a new instance method 'float.hex'
2686 and a new class method 'float.fromhex' to convert floating-point
2687 numbers to and from hexadecimal strings, respectively.
2688
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002689- Issue #2235: __hash__ is once again inherited by default. To allow
2690 collections.Hashable to remain meaningful in the presence of the
2691 default hash implementation (object.__hash__), it is now possible
2692 to explicit block inheritance of hash by setting __hash__=None at
2693 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2694 level.
2695
Nick Coghlanb028f502008-07-13 14:52:36 +00002696- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2697 the parent module cannot be found while performing an absolute import.
2698 This means that an incorrectly defined __package__ attribute will
2699 now only prevent relative imports in that module rather than causing
2700 all imports from that module to fail.
2701
Nick Coghlan14ff9942008-07-08 14:21:42 +00002702- Issue #2517: Allow unicode messages in Exceptions again by correctly

2712 another thread's dictionary.
2713
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002714- Issue #3004: Minor change to slice.indices(): the start and stop
2715 arguments are now treated identically, making the behaviour easier
2716 to describe and understand. For example, slice(None, -10,
2717 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2718 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2719 10, -1).
2720
Georg Brandl278fc502008-07-19 12:46:12 +00002721- Issue #3219: Calling a function with repeated keyword arguments,
2722 f(a=2, a=23), would not cause a syntax error. This was a regression
2723 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002761- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2762 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002763 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002764 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002780- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3170
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003171- On MacOS X it is now possible to install the framework in 64-bit
3172 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003173 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003174
3175 This is controlled by the configure argument ``--with-universal-archs``:
3176
3177 - ``--with-universal-archs=all``: install 4-way universal
3178
3179 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3180
3181 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3182
3183 This option should be used in combination with ``--enable-universalsdk=``.
3184
3185 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 +00003235- Issue #1631171: Re-implement the 'warnings' module in C (the
3236 original Python code has been kept as backup). This will allow for
3237 using the 'warning's machinery in such places as the parser where
3238 use of pure Python code is not possible. Both the ``showarning()``
3239 and ``formatwarning()`` gain an optional 'line' argument which is
3240 not called by default for backwards-compatibility reasons. Setting
3241 ``warnings.showwarning()`` to an implementation that lacks support
3242 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003284- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003285 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003305- Issue #2550: The approach used by client/server code for obtaining
3306 ports to listen on in network-oriented tests has been refined in an
3307 effort to facilitate running multiple instances of the entire
3308 regression test suite in parallel without issue.
3309 test_support.bind_port() has been fixed such that it will always
3310 return a unique port -- which wasn't always the case with the
3311 previous implementation, especially if socket options had been set
3312 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3313 new implementation of bind_port() will actually raise an exception
3314 if it is passed an AF_INET/SOCK_STREAM socket with either the
3315 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3316 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3317 the socket it's been passed. This currently only applies to
3318 Windows. This option prevents any other sockets from binding to the
3319 host/port we've bound to, thus removing the possibility of the
3320 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3321 when a second SOCK_STREAM socket binds and accepts to a host/port
3322 that's already been bound by another socket. The optional preferred
3323 port parameter to bind_port() has been removed. Under no
3324 circumstances should tests be hard coding ports!
3325
3326 test_support.find_unused_port() has also been introduced, which will
3327 pass a temporary socket object to bind_port() in order to obtain an
3328 unused port. The temporary socket object is then closed and
3329 deleted, and the port is returned. This method should only be used
3330 for obtaining an unused port in order to pass to an external program
3331 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3332 a parameter to a server-oriented class that doesn't give you direct
3333 access to the underlying socket used.
3334
3335 Finally, test_support.HOST has been introduced, which should be used
3336 for the host argument of any relevant socket calls (i.e. bind and
3337 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003338
3339 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003340 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003341 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3342 test_asynchat and test_socket_ssl.
3343
Georg Brandl3ee81df2008-05-17 18:14:43 +00003344 It is now possible for multiple instances of the regression test
3345 suite to run in parallel without issue.

3611Core and builtins
3612-----------------
3613
Fred Drakea8ee94b2008-03-01 02:45:07 +00003614- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003615 644. The mode is now inherited from the py file.

3618
3619- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003620
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003621- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003622 issue 215555 for a discussion.
3623
Eric Smitha73fbe72008-02-23 03:09:44 +00003624- Added the future_builtins module, which contains hex() and oct().
3625 These are the PEP 3127 version of these functions, designed to be
3626 compatible with the hex() and oct() builtins from Python 3.0. They
3627 differ slightly in their output formats from the existing, unchanged
3628 Python 2.6 builtins. The expected usage of the future_builtins
3629 module is:
3630 from future_builtins import hex, oct
3631
Eric Smith7ef40bf2008-02-20 23:34:22 +00003632- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3633 exponents for exponents with absolute value < 100. Follows C99
3634 standard. This is a change on Windows, which would use 3 digits.
3635 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3636 so that any alterations it does to the resulting string will be
3637 available in stringlib/formatter.h (for float.__format__).
3638
Eric Smith5a3c1352008-02-19 13:21:56 +00003639- Implemented PEP 3101, Advanced String Formatting. This adds a new
3640 builtin format(); a format() method for str and unicode; a
3641 __format__() method to object, str, unicode, int, long, float, and
3642 datetime; the class string.Formatter; and the C API
3643 PyObject_Format().
3644
Georg Brandl3ee81df2008-05-17 18:14:43 +00003645- Fixed several potential crashes, all caused by specially crafted
3646 __del__ methods exploiting objects in temporarily inconsistent
3647 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003648
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003649- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003650 prevent a possible crash: an Abstract Base Class would try to access
3651 a slot on a registered virtual subclass.

3654 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003655
Georg Brandl3ee81df2008-05-17 18:14:43 +00003656- Clear all free lists during a gc.collect() of the highest generation
3657 in order to allow pymalloc to free more arenas. Python may give back
3658 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003659
Georg Brandl3ee81df2008-05-17 18:14:43 +00003660- Issue #2045: Fix an infinite recursion triggered when printing a
3661 subclass of collections.defaultdict, if its default_factory is set
3662 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003663
Christian Heimesf75dbef2008-02-08 00:11:31 +00003664- Fixed a minor memory leak in dictobject.c. The content of the free
3665 list was not freed on interpreter shutdown.
3666
Georg Brandl3ee81df2008-05-17 18:14:43 +00003667- Limit free list of method and builtin function objects to 256
3668 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003669
Georg Brandl3ee81df2008-05-17 18:14:43 +00003670- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3671 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003672 to compact the internal free lists of pre-allocted ints and floats.
3673
Georg Brandl3ee81df2008-05-17 18:14:43 +00003674- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3675 calls. Python expected the return type int but the fork familie
3676 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003677
Georg Brandl3ee81df2008-05-17 18:14:43 +00003678- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3679 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003680
Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3682 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003683
Georg Brandl3ee81df2008-05-17 18:14:43 +00003684- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3685 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003686
Georg Brandl3ee81df2008-05-17 18:14:43 +00003687- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3688 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003689
Georg Brandl3ee81df2008-05-17 18:14:43 +00003690- Patch #1473257: generator objects gain a gi_code attribute. This is
3691 the same object as the func_code attribute of the function that
3692 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003693
Georg Brandl3ee81df2008-05-17 18:14:43 +00003694- Issue #1920: "while 0" statements were completely removed by the
3695 compiler, even in the presence of an "else" clause, which is
3696 supposed to be run when the condition is false. Now the compiler
3697 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003698
Guido van Rossumeead05f2008-01-24 18:21:02 +00003699- A few crashers fixed: weakref_in_del.py (issue #1377858);
3700 loosing_dict_ref.py (issue #1303614, test67.py);
3701 borrowed_ref_[34].py (not in tracker).
3702
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003703- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003704 suppressed while an extension is loaded by calling SetErrorMode in
3705 dynload_win.c. The error is still reported properly.
3706
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003708 several extension methods and modules do not work without unicode
3709 support.
3710
Georg Brandl26543b12008-01-21 18:36:51 +00003711- Issue #1882: when compiling code from a string, encoding cookies in the
3712 second line of code were not always recognized correctly.
3713
Georg Brandl14404b62008-01-19 19:27:05 +00003714- Issue #1679: "0x" was taken as a valid integer literal.
3715
Georg Brandl6caad7d2008-01-26 14:19:22 +00003716- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003717 added.
3718
Christian Heimesc94e2b52008-01-14 04:13:37 +00003719- sys.float_info / PyFloat_GetInfo: The floating point information
3720 object was converted from a dict to a specialized structseq object.
3721
Georg Brandl3ee81df2008-05-17 18:14:43 +00003722- Patch #1816: Added sys.flags structseq. It exposes the status of
3723 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003724
Georg Brandl3ee81df2008-05-17 18:14:43 +00003725- Objects/structseq.c: Implemented new structseq representation. The
3726 patch makes structseqs (e.g. the return value of os.stat) more
3727 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003728
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Patch #1700288: added a type attribute cache that caches method
3730 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003731
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003732- Bug #1776: __import__() no longer accepts filenames on any platform.
3733 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003734
Georg Brandlaed6c662008-01-07 17:25:53 +00003735- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3736
Georg Brandl3ee81df2008-05-17 18:14:43 +00003737- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3738 envvar and sys.dont_write_bytecode attribute. All these can be set
3739 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003740
Georg Brandl3ee81df2008-05-17 18:14:43 +00003741- Improve some exception messages when Windows fails to load an
3742 extension module. Now we get for example '%1 is not a valid Win32
3743 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003744

3748 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003749
Christian Heimes0a8143f2007-12-18 23:22:54 +00003750- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003751 and INF. float("nan"), float("inf") and float("-inf") now work on
3752 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003753
Georg Brandl3ee81df2008-05-17 18:14:43 +00003754- Compiler now generates simpler and faster code for dictionary
3755 literals. The oparg for BUILD_MAP now indicates an estimated
3756 dictionary size. There is a new opcode, STORE_MAP, for adding
3757 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003758
Georg Brandl3ee81df2008-05-17 18:14:43 +00003759- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Patch #1739468: Directories and zipfiles containing a __main__.py
3787 file can now be directly executed by passing their name to the
3788 interpreter. The directory/zipfile is automatically inserted as the
3789 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003790
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791- Issue #1265: Fix a problem with sys.settrace, if the tracing
3792 function uses a generator expression when at the same time the
3793 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003794
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003795- sets and frozensets now have an isdisjoint() method.
3796

3798
Neal Norwitz44f326e2007-10-05 05:29:17 +00003799- Fix warnings found by the new version of the Coverity checker.
3800
Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- The enumerate() builtin function is no longer bounded to sequences
3802 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3803 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003804
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- Issue #1686386: Tuple's tp_repr did not take into account the
3806 possibility of having a self-referential tuple, which is possible
3807 from C code. Nor did object's tp_str consider that a type's tp_str
3808 could do something that could lead to an inifinite recursion.
3809 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3810 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- Issue #1164: It was possible to trigger deadlock when using the
3813 'print' statement to write to a file since the GIL was not released
3814 as needed. Now PyObject_Print() does the right thing along with
3815 various tp_print implementations of the built-in types and those in
3816 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003817
Georg Brandl3ee81df2008-05-17 18:14:43 +00003818- Issue #1147: Exceptions were directly allowing string exceptions in
3819 their throw() method even though string exceptions no longer
3820 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003821
Georg Brandl3ee81df2008-05-17 18:14:43 +00003822- Issue #1096: Prevent a segfault from getting the repr of a very
3823 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003824
Brett Cannon1e534b52007-09-07 04:18:30 +00003825- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003826 PyObject_Call() never calling back out to Python code to trigger
3827 recursion depth updates/checks. Required the creation of a static
3828 RuntimeError instance in case normalizing an exception put the
3829 recursion check value past its limit. Fixes crashers
3830 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003831

Neal Norwitz0ac60192007-05-27 04:08:54 +00003845- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846 __*__ attributes. (Some already existed, e.g., __doc__ and
3847 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003848
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003849- Add -3 option to the interpreter to warn about features that are
3850 deprecated and will be changed/removed in Python 3.0.
3851
Georg Brandl2134e752007-05-21 20:34:16 +00003852- Patch #1686487: you can now pass any mapping after '**' in function
3853 calls.
3854
Collin Winter62903052007-05-18 23:11:24 +00003855- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003856 "except E as target:". This is to provide forwards compatibility
3857 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003858
Brett Cannon229cee22007-05-05 01:34:02 +00003859- Deprecate BaseException.message as per PEP 352.
3860
Georg Brandl3ee81df2008-05-17 18:14:43 +00003861- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003862 inherited from a builtin base.
3863
Vinay Sajip8549ce32007-05-06 17:53:37 +00003864- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003865 setting a plain string, ie don't expand to single letter identifiers.
3866
Raymond Hettinger13936692007-04-11 18:40:58 +00003867- Request #1191699: Slices can now be pickled.
3868
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003869- Request #1193128: str.translate() now allows a None argument for
3870 translations that only remove characters without re-mapping the
3871 remaining characters.
3872
Georg Brandl5cb76c12007-03-21 09:00:39 +00003873- Patch #1682205: a TypeError while unpacking an iterable is no longer
3874 masked by a generic one with the message "unpack non-sequence".
3875
Neal Norwitzaa754b72007-03-21 06:39:48 +00003876- Remove unused file Python/fmod.c.
3877
Guido van Rossum143b5642007-03-23 04:58:42 +00003878- Bug #1683368: The object.__init__() and object.__new__() methods are
3879 now stricter in rejecting excess arguments. The only time when
3880 either allows excess arguments is when it is not overridden and the
3881 other one is. For backwards compatibility, when both are
3882 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003883 warning later). Also, type.__init__() insists on the same signature
3884 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003885
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3887 object to complex using its __complex__() method before falling back
3888 to the __float__() method. Therefore, the functions in the cmath
3889 module now can operate on objects that define a __complex__()
3890 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003891
Georg Brandl3ee81df2008-05-17 18:14:43 +00003892- Patch #1623563: allow __class__ assignment for classes with
3893 __slots__. The old and the new class are still required to have the

Georg Brandl3ee81df2008-05-17 18:14:43 +00004964 time so that opening a database previously created with the DB_DUP
4965 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4966 opens. Specifically: dictionary assignment to a DB object will
4967 replace all values for a given key when the database allows
4968 duplicate values. DB users should use DB.put(k, v) when they want
4969 to store duplicates; not DB[k] = v.

4976 characters with ASCII value less than 32. Also, it correctly quotes
4977 dots only if they occur on a single line, as opposed to the previous
4978 behavior of quoting dots if they are the second character of any
4979 line.
