83 and read operations on write-only file objects. On Windows, the system C
84 library would return a bogus result; on Solaris, it was possible to crash
85 the interpreter. Patch by Stefan Krah.
86
Barry Warsawb1e66ee2010-02-05 18:45:25 +000087- Issue #7853: Normalize exceptions before they are passed to a context

102
Antoine Pitroue80a6a42010-01-17 12:26:20 +0000103- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
104 could crash in many places because of the PyByteArray_AS_STRING() macro
105 returning NULL. The macro now returns a statically allocated empty

113 alpha 2, including: (1) a serious 'wrong output' bug that could
114 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
115 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +0000116 strings corresponding to subnormal values, (3) a memory leak for
117 some values large enough to cause overflow, and (4) a number of
118 flaws that could lead to incorrectly rounded results.
Mark Dickinson8efef5c2010-01-12 22:23:56 +0000119
Brett Cannon3ffa43d2010-01-14 20:00:28 +0000120- Issue #7319, #7770: Silence DeprecationWarning by default when -3 is not

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

148 specified, rather than fall through to AF_PACKET (in the `socket` module).
149 Also, raise ValueError rather than TypeError when an unknown TIPC address
150 type is specified. Patch by Brian Curtin.

Vinay Sajip28c382f2010-02-04 18:48:53 +0000152- logging: Implemented PEP 391.
153

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

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

173 the release file is empty.
174
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000175- Issue #7748: Since unicode values are supported for some metadata options
176 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
177 encoded string for them. This ensure that the upload and register commands
178 send the right values to PyPI without any error.
179
R. David Murrayed44dfa2010-01-16 05:15:17 +0000180- Issue #1670765: Prevent email.generator.Generator from re-wrapping

256-----------------
257
Benjamin Petersonecdae192010-01-04 00:43:01 +0000258- The __complex__ method is now looked up on the class of instances to make it
259 consistent with other special methods.
260
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000261- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
262 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
263
Mark Dickinson1b34d252010-01-01 17:27:30 +0000264- Issue #5080: A number of functions and methods previously produced a
265 DeprecationWarning when passed a float argument where an integer was
266 expected. These functions and methods now raise TypeError instead.
267 The majority of the effects of this change are in the extension
268 modules, but some core functions and methods are affected: notably
269 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
270 methods.
271
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000272- Issue #7604: Deleting an unset slotted attribute did not raise an
273 AttributeError.

280
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000281- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
282 used to drop the time part of the result.
283
Mark Dickinson46572832009-12-27 14:55:57 +0000284- Issue #1811: improve accuracy and cross-platform consistency for
285 true division of integers: the result of a/b is now correctly
286 rounded for ints a and b (at least on IEEE 754 platforms), and in
287 particular does not depend on the internal representation of a long.
288
Ezio Melottif84caf42009-12-24 22:25:17 +0000289- Issue #6108: unicode(exception) and str(exception) should return the same

291
Ronald Oussoren92919a62009-12-24 13:30:58 +0000292- Issue #6834: replace the implementation for the 'python' and 'pythonw'
293 executables on OSX.
294

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

318 by Arfrever.
319
Antoine Pitrou80157252010-01-08 19:20:17 +0000320- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles

435 with invalid values.
436
Eric Smithc4ab8332009-11-29 17:40:57 +0000437- Issue #3382: 'F' formatting for float and complex now convert the
438 result to upper case. This only affects 'inf' and 'nan', since 'f'
439 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000440
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000441- Remove switch from "%f" formatting to "%g" formatting for floats

445 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
446 requested 120 significant digits instead.
447

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000452- Issue #7085: Fix crash when importing some extensions in a thread
453 on MacOSX 10.6.
454
Mark Dickinsonb678de82009-11-19 18:41:49 +0000455- Issue #7117: repr(x) for a float x returns a result based on the
456 shortest decimal string that's guaranteed to round back to x under
457 correct rounding (with round-half-to-even rounding mode).
458 Previously it gave a string based on rounding x to 17 decimal digits.
459 repr(x) for a complex number behaves similarly. On platforms where
460 the correctly-rounded strtod and dtoa code is not supported (see below),
461 repr is unchanged.
462
463- Issue #7117: On almost all platforms: float-to-string and
464 string-to-float conversions within Python are now correctly rounded.
465 Places these conversions occur include: str for floats and complex
466 numbers; the float and complex constructors; old-style and new-style
467 numeric formatting; serialization and deserialization of floats and
468 complex numbers using marshal, pickle and json; parsing of float and
469 imaginary literals in Python code; Decimal-to-float conversion.
470
471 The conversions use a Python-adapted version of David Gay's
472 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
473 functions. This code is supported on Windows, and on Unix-like
474 platforms using gcc, icc or suncc as the C compiler. There may be a
475 small number of platforms on which correct operation of this code
476 cannot be guaranteed, so the code is not used: notably, this applies
477 to platforms where the C double format is not IEEE 754 binary64, and
478 to platforms on x86 hardware where the x87 FPU is set to 64-bit
479 precision and Python's configure script is unable to determine how
480 to change the FPU precision. On these platforms conversions use the
481 platform strtod and dtoa, as before.
482
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000483- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000484 now uses the correctly-rounded string <-> float conversions
485 described above (when available), and so produces correctly rounded
486 results that will display nicely under the float repr. There are
487 two related small changes: (1) round now accepts any class with an
488 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000489 floats for the second argument), and (2) an excessively large second
490 integer argument (e.g., round(1.234, 10**100)) no longer raises an
491 exception.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000619- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
620 statement and correctly lookup the __enter__ and __exit__ special methods.
621
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000622- Issue #5829: complex("1e500") no longer raises OverflowError. This
623 makes it consistent with float("1e500") and interpretation of real
624 and imaginary literals.
625
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000626- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
627
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000628- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
629 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000630
R. David Murray525cffc2009-05-13 13:07:14 +0000631- Issue #5994: the marshal module now has docstrings.
632
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000633- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
634 (1) inf and nan strings with trailing whitespace were incorrectly
635 rejected; (2) parsing of strings representing infinities and nans
636 was locale aware; and (3) the interpretation of fromhex('-nan')
637 didn't match that of float('-nan').
638
Eric Smitha985a3a2009-05-05 18:26:08 +0000639- Issue #5920: For float.__format__, change the behavior with the
640 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
641 to be like 'g' but with at least one decimal point and with a
642 default precision of 12. Previously, the behavior the same but with
643 a default precision of 6. This more closely matches str(), and
644 reduces surprises when adding alignment flags to the empty
645 presentation type. This also affects the new complex.__format__ in
646 the same way.
647
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000648- Issue #5890: in subclasses of 'property' the __doc__ attribute was
649 shadowed by classtype's, even if it was None. property now
650 inserts the __doc__ into the subclass instance __dict__.
651
Antoine Pitrou653dece2009-05-04 18:32:32 +0000652- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
653 sequences. Patch by Nick Barnes and Victor Stinner.
654
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000655- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000656 format(complex(1, 2./3), '.5') now produces a sensible result.
657
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000658- Issue #5864: Fix empty format code formatting for floats so that it
659 never gives more than the requested number of significant digits.
660
Eric Smithcac7af62009-04-27 19:04:37 +0000661- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

665 titlecase, but not their own uppercase.
666
Eric Smith068f0652009-04-25 21:40:15 +0000667- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
668 _PyOS_double_to_string or PyOS_double_to_string.
669
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000670- Issue #5283: Setting __class__ in __del__ caused a segfault.
671
Mark Dickinson95bc9802009-04-24 12:46:53 +0000672- Issue #5816: complex(repr(z)) now recovers z exactly, even when
673 z involves nans, infs or negative zeros.
674
Eric Smithaca19e62009-04-22 13:29:05 +0000675- Implement PEP 378, Format Specifier for Thousands Separator, for
676 floats, ints, and longs.
677
678- Issue #5515: 'n' formatting for ints, longs, and floats handles
679 leading zero formatting poorly.
680
681- Issue #5772: For float.__format__, don't add a trailing ".0" if
682 we're using no type code and we have an exponent.
683
Mark Dickinson6736cf82009-04-20 21:13:33 +0000684- Issue #3166: Make long -> float (and int -> float) conversions
685 correctly rounded.
686
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000687- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
688 some builtin types.
689
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000690- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000691 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000692
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000693- Issue #5759: float() didn't call __float__ on str subclasses.
694
Georg Brandl3c4a5462009-04-12 12:08:12 +0000695- Issue #5704: the "-3" command-line option now implies "-t".
696
R. David Murray0374a822009-04-09 21:54:50 +0000697- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
698 its clarity and its speed.
699
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000700- Issue #2396: the memoryview object was backported from Python 3.1.
701
Georg Brandld3f03fa2009-04-02 18:09:04 +0000702- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

Brett Cannon15ba4da2009-04-01 18:03:59 +0000705- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
706
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000707- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
708 the end sys.path, for compatibility with the system install of Python.
709
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000710- Issue #4688: Add a heuristic so that tuples and dicts containing only
711 untrackable objects are not tracked by the garbage collector. This can
712 reduce the size of collections and therefore the garbage collection overhead
713 on long-running programs, depending on their particular use of datatypes.
714
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000715- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
716 improve its performance. Long divisions and remainder operations
717 are now between 50% and 150% faster.
718
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000719- Issue #4258: Make it possible to use base 2**30 instead of base
720 2**15 for the internal representation of integers, for performance
721 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
722 --enable-big-digits option to configure, which overrides the
723 default. Add sys.long_info structseq to provide information about
724 the internal format.
725
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000726- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
727 result traceback.__members__ no longer exists.)
728
Mark Dickinson6b265f12009-03-18 16:07:26 +0000729- Issue #4474: PyUnicode_FromWideChar now converts characters outside
730 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
731 and sizeof(Py_UNICODE) == 2.
732
Eric Smith6f42edb2009-03-14 11:57:26 +0000733- Issue #5237: Allow auto-numbered fields in str.format(). For
734 example: '{} {}'.format(1, 2) == '1 2'.
735
Brett Cannon6c4cff02009-03-11 04:51:06 +0000736- Issue #3652: Make the 'line' argument for warnings.showwarning() a
737 requirement. Means the DeprecationWarning from Python 2.6 can go away.
738
Eric Smithe9fb6862009-02-20 14:02:36 +0000739- Issue #5247: Improve error message when unknown format codes are
740 used when using str.format() with str, unicode, long, int, and
741 float arguments.
742
Raymond Hettinger08259e82009-02-18 23:10:19 +0000743- Running Python with the -3 option now also warns about classic division
744 for ints and longs.
745
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000746- Issue #5260: Long integers now consume less memory: average
747 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
748 on a 64-bit system.
749
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000750- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
751 rotating the object pointer by 4 bits to the right.
752
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000753- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
754 it now forces its argument to double before testing for infinity.
755
Benjamin Petersone18ef192009-01-20 14:21:16 +0000756- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
757
Georg Brandl29c6a282009-04-05 20:23:13 +0000758- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000759 were suppressing all exceptions. These include list(), filter(), map(),
760 zip(), and bytearray().
761
Benjamin Peterson596d3062009-01-19 15:42:23 +0000762- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
763 functions.
764
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000765- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

769
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000770- Issue #4935: The overflow checking code in the expandtabs() method common
771 to str, bytes and bytearray could be optimized away by the compiler, letting
772 the interpreter segfault instead of raising an error.
773
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000774- Issue #3720: Fix a crash when an iterator modifies its class and removes its

780
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000781- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
782 collecting the oldest generation) so that allocating lots of objects without
783 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000784 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000785 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

788
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000789- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
790 an existing .py counterpart, override the co_filename attributes of all
791 code objects if the original filename is obsolete (which can happen if the
792 file has been renamed, moved, or if it is accessed through different paths).
793 Patch by Ziga Seilnacht and Jean-Paul Calderone.
794
Martin v. Löwis5344c992009-01-02 20:32:55 +0000795- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000797- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
798 file with `str' filename on Windows.
799
Antoine Pitrouaa687902009-01-01 14:11:22 +0000800- Issue #3680: Reference cycles created through a dict, set or deque iterator
801 did not get collected.
802
Nick Coghlan180e4002008-12-30 01:18:48 +0000803- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
804 where the tp_hash and tp_dict slots are both NULL.
805
Benjamin Peterson7af65562008-12-29 17:56:58 +0000806- Issue #4764: With io.open, IOError.filename is set when trying to open a
807 directory on POSIX systems.
808
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000809- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

813 bytearray.translate(). It was always allowed for bytes.translate().
814
Skip Montanarof205c132008-12-23 03:30:15 +0000815- Added test case to ensure attempts to read from a file opened for writing
816 fail.
817
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000818- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
819 print elapsed times, not only when some objects are uncollectable /
820 unreachable. Original patch by Neil Schemenauer.
821
Mark Dickinson1a707982008-12-17 16:14:37 +0000822- Issue #3439: Add a bit_length method to int and long.

828 context manager returns a value that cannot be converted to a bool.
829
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000830- Issue #4597: Fixed several opcodes that weren't always propagating
831 exceptions.
832
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000833- Issue #4445: Replace "sizeof(PyStringObject)" with
834 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
835 str instances. On a typical machine this saves 3 bytes of memory
836 (on average) per string allocation.
837
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000838- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
839 interpreter to abort ("Fatal Python error: Could not reset the stack!")
840 instead of throwing a MemoryError.
841
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000842- Issue #3689: The list reversed iterator now supports __length_hint__
843 instead of __len__. Behavior now matches other reversed iterators.
844
Benjamin Petersonc078f922008-11-21 22:27:24 +0000845- Issue #4367: Python would segfault during compiling when the unicodedata

847
Vinay Sajip213faca2008-12-03 23:22:58 +0000848- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000849 method on file objects with closefd=False. The file descriptor is still
850 kept open but the file object behaves like a closed file. The ``FileIO``
851 object also got a new readonly attribute ``closefd``.
852
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000853- Issue #4348: Some bytearray methods returned that didn't cause any change to
854 the bytearray, returned the same bytearray instead of a copy.
855
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000856- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

864
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000865- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
866 method does not return iterators for the 4th and 5th items.
867
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000868- Issue #4209: Enabling unicode_literals and the print_function in the same
869 __future__ import didn't work.
870
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000871- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000872 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000873
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000874- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
875 returned a path longer than MAX_PATH. (But It's doubtful this code path is
876 really executed because I cannot move to such directory on win2k)
877
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000878- Issue #4069: When set.remove(element) is used with a set element, the element
879 is temporarily replaced with an equivalent frozenset. But the eventual
880 KeyError would always report the empty frozenset([]) as the missing key. Now
881 it correctly refers to the initial element.
882
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000883- Issue #4509: Various issues surrounding resize of bytearray objects to

899 returned them on 64bit platforms.
900
Walter Dörwalded960ac2009-05-03 22:36:33 +0000901- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
902 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
903 step. This avoids problems with counting UTF-8 bytes that ignores the effect
904 of using the replace error handler in PyUnicode_DecodeUTF8().
905
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000906- Issue #3739: The unicode-internal encoder now reports the number of characters

Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000909- Issue #2422: When compiled with the ``--with-valgrind`` option, the
910 pymalloc allocator will be automatically disabled when running under
911 Valgrind. This gives improved memory leak detection when running
912 under Valgrind, while taking advantage of pymalloc at other times.

Michael Foord07ef4872009-05-02 22:43:34 +00001448- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were added.
1449 addCleanup allows you to add cleanup functions that will be called
1450 unconditionally (after setUp if setUp fails, otherwise after tearDown). This
1451 allows for much simpler resource allocation and deallocation during tests.
1452
1453- Issue #3379: unittest.main now takes an optional exit argument. If False main
1454 doesn't call sys.exit allowing it to be used from the interactive interpreter.

1464
Michael Foord345b2fe2009-04-02 03:20:38 +00001465- Issue #5663: better failure messages for unittest asserts. Default assertTrue
1466 and assertFalse messages are now useful. TestCase has a longMessage attribute.
1467 This defaults to False, but if set to True useful error messages are shown in
1468 addition to explicit messages passed to assert methods.

1478 instead of performing them in functions. Helps prevent import deadlocking in
1479 threads.
1480
Raymond Hettinger66c4a6b2009-04-01 18:50:56 +00001481- Issue #5647: MutableSet.__iand__() no longer mutates self during iteration.

1508
Guilherme Polo1972d162009-03-27 21:43:08 +00001509- Adjusted _tkinter to compile without warnings when WITH_THREAD is not

1519 not given a callable so that code to be tested can be written inline using
1520 a with statement.
1521
1522- The unittest.TestCase.assertEqual() now displays the differences in lists,
1523 tuples, dicts and sets on failure. Many new handy type and comparison

Antoine Pitrou59c44f32009-10-30 17:07:08 +00002148- Issue #7222: Make thread "reaping" more reliable so that reference
2149 leak-chasing test runs give sensible results. The previous method of
2150 reaping threads could return successfully while some Thread objects were
2151 still referenced. This also introduces a new private function:

2170 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

2172 skip the tests if DISPLAY is defined but can't be used.
2173
Antoine Pitrou4698d992009-05-31 14:20:14 +00002174- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

2178 it easy to import both normal and optimised versions of modules.
2179 test_heapq and test_warnings have been adjusted to use it, tests for
2180 other modules with both C and Python implementations in the stdlib
2181 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00002189- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00002190 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00002191 from test support, which does the conversion.

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00002273 AttributeError instead of RuntimeError, depending in which C API call
2274 exactly the recursion limit is exceeded. Consequently, both exception types
2275 are caught and silenced.

2289Core and Builtins
2290-----------------
2291
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002292- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2293
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002294- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2295 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2296 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2297 ``printf`` function, whereas PyString_FromFormat has an independent
2298 implementation and uses "%zd" on all platforms for size_t values.
2299 This makes a difference on win64, where ``printf`` needs "%Id" to display
2300 64bit values.
2301
Benjamin Peterson97179b02008-09-09 20:55:01 +00002302- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2303 error.
2304
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002305- Issue #3777: long() applied to a float object now always return a long
2306 object; previously an int would be returned for small values. the __long__
2307 method is allowed to return either an int or a long, but the behaviour of
2308 float objects should not change to respect backward compatibility.
2309
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002310- Issue #3751: str.rpartition would perform a left-partition when called with
2311 a unicode argument.
2312
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002313- Issue #3683: Fix compilation when --without-threads is given.
2314
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002315- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002316 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002317 was correctly parsed but parsing of subsequent arguments failed.
2318
Vinay Sajip35e3b032008-09-01 14:33:59 +00002319- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002320 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2321 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2322 when given a tuple of classes as second argument, were looking up
2323 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2324 type object.
2325
Neal Norwitz18aa3882008-08-24 05:04:52 +00002326- Fix crashes on memory allocation failure found with failmalloc.
2327
2328- Fix memory leaks found with valgrind and update suppressions file.
2329
2330- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2331
2332- Fix problem using wrong name in decimal module reported by pychecker.
2333
Christian Heimes7d4c3172008-08-22 19:47:25 +00002334- Silenced another compiler warning about a used but not defined
2335 function 'stringlib_contains_obj'.
2336
Benjamin Peterson712ee922008-08-24 18:10:20 +00002337- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2338 ``__delslice__``.
2339
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002340- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2341 library targets in the Makefile.
2342
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002343- Issue #1204: The configure script now tests for additional libraries
2344 that may be required when linking against readline. This fixes issues
2345 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

2367
Nick Coghland2e09382008-09-11 12:11:06 +00002368- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002369 return a list or None rather than a custom object.
2370
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002371- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2395 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2396 for catch_warnings() also led to an improvement in the raising of a
2397 DeprecationWarning related to warnings.warn_explicit().
2398
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002399- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002463What's New in Python 2.6 beta 3?
2464================================
2465
Barry Warsaw07a4a382008-08-21 01:15:08 +00002466*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002467
2468Core and Builtins
2469-----------------
2470
Guido van Rossumf8402962008-08-20 15:01:50 +00002471- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2472 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2473 extensions do not automatically benefit from the class attribute
2474 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2475 to their tp_flags field if they care. This is a backwards
2476 compatibility feature; in 3.0, all types will use the cache by
2477 default.
2478
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002479- Keyword arguments can now follow starred arguments. (``f(a, *args,
2480 keyword=23)`` is now valid syntax.)
2481
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002482- ctypes function pointers that are COM methods have a boolean True
2483 value again.
2484
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002485- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2486 by denying s# to parse objects that have a releasebuffer procedure,
2487 and introducing s*.
2488
Georg Brandl1e13ea92008-08-11 09:07:59 +00002489- Issue #3537: Fix an assertion failure when an empty but presized dict
2490 object was stored in the freelist.
2491
Mark Dickinsonb6467572008-08-04 21:30:09 +00002492- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2493 ValueError consistently across platforms.
2494
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002495- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2496 (64bit Unix, for example), unichr() would truncate its argument and return
2497 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2498
Neal Norwitze7d8be82008-07-31 17:17:14 +00002499- Apply security patches from Apple.
2500
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002501- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2502 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2503
Antoine Pitrou92f82162008-07-25 22:22:08 +00002504- Issue #1819: function calls with several named parameters are now on
2505 average 35% faster (as measured by pybench).
2506
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002507- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2508 the python debugger steps into a class statement: the free variables (local
2509 variables defined in an outer scope) would be deleted from the outer scope.
2510
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002511- Issue #2620: Overflow checking when allocating or reallocating memory
2512 was not always being done properly in some python types and extension
2513 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2514 all been updated to perform better checks and places in the code that
2515 would previously leak memory on the error path when such an allocation
2516 failed have been fixed.

2524 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2525
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002526- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2527 version reported by these tools does not necessarily follow the python
2528 version numbering scheme, so the module is less strict when parsing it.
2529
Nick Coghlanf70385a2008-08-18 12:42:46 +00002530- Issue #2235: Added Py3k warnings for types which will become unhashable
2531 under the stricter __hash__ inheritance rules in 3.0. Several types
2532 which did not meet the rules for hash invariants and were already
2533 unhashable in 3.0 have now been explicitly flagged as unhashable in
2534 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2535 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2536
Brett Cannon88f801d2008-08-18 00:46:22 +00002537- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2538 imported into the module but exposed as part of the module's API.
2539
Brett Cannon7b96f072008-08-18 00:41:11 +00002540- Remove an unneeded import of abc.ABCMeta from 'inspect'.

2545
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002546- Issue #3575: Incremental decoder's decode function now takes bytearray
2547 by using 's*' instead of 't#'.
2548
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002549- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002550 fails unicode conversion on 2nd parameter. (windows only)
2551
Facundo Batista94f243a2008-08-17 03:38:39 +00002552- Issue 2464. urllib2 now supports a malformation in the URL received
2553 in a redirect.
2554
Brett Cannonabe423e2008-08-16 21:47:07 +00002555- Silence the DeprecationWarning raised when importing mimetools in

Brett Cannonabe423e2008-08-16 21:47:07 +00002557
Facundo Batistaeb90b782008-08-16 14:44:07 +00002558- Issue #2776: fixed small issue when handling an URL with double slash
2559 after a 302 response in the case of not going through a proxy.
2560
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002561- Issue #2676: in the email package, content-type parsing was hanging on
2562 pathological input because of quadratic or exponential behaviour of a

Antoine Pitroude781a42008-08-09 12:43:23 +00002606 asking for a specific length. This problem only affected files opened

2650
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002651- Issue #643841: The language reference now provides more detailed

2663-----------------
2664
Georg Brandl3e483f62008-07-16 22:57:41 +00002665- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2666 its methods now allow for items objects that can be converted to
2667 an integer using operator.index().
2668
Mark Dickinson64b7e502008-07-16 09:40:03 +00002669- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2670 produced a ValueError instead of giving the correct float.
2671
Eric Smitha5fa5a22008-07-16 00:11:49 +00002672- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2673 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2674
Mark Dickinson7103aa42008-07-15 19:08:33 +00002675- Issue #3008: the float type has a new instance method 'float.hex'
2676 and a new class method 'float.fromhex' to convert floating-point
2677 numbers to and from hexadecimal strings, respectively.
2678
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002679- Issue #2235: __hash__ is once again inherited by default. To allow
2680 collections.Hashable to remain meaningful in the presence of the
2681 default hash implementation (object.__hash__), it is now possible
2682 to explicit block inheritance of hash by setting __hash__=None at
2683 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2684 level.
2685
Nick Coghlanb028f502008-07-13 14:52:36 +00002686- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2687 the parent module cannot be found while performing an absolute import.
2688 This means that an incorrectly defined __package__ attribute will
2689 now only prevent relative imports in that module rather than causing
2690 all imports from that module to fail.
2691
Nick Coghlan14ff9942008-07-08 14:21:42 +00002692- Issue #2517: Allow unicode messages in Exceptions again by correctly

2702 another thread's dictionary.
2703
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002704- Issue #3004: Minor change to slice.indices(): the start and stop
2705 arguments are now treated identically, making the behaviour easier
2706 to describe and understand. For example, slice(None, -10,
2707 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2708 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2709 10, -1).
2710
Georg Brandl278fc502008-07-19 12:46:12 +00002711- Issue #3219: Calling a function with repeated keyword arguments,
2712 f(a=2, a=23), would not cause a syntax error. This was a regression
2713 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002714
Georg Brandl278fc502008-07-19 12:46:12 +00002715- Issue #2862: Make int and float freelist management consistent with
2716 other freelists. Changes their CompactFreeList apis into

2723 api functions without holding the GIL, which could lead to a fatal
2724 error when they failed.
2725
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002726- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002751- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2752 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002753 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002754 content-length. The problem had been corrected in the 2.4 branch, but never
2755 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002770- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2772
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002773- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Benjamin Peterson23681932008-05-12 21:42:13 +00003140
Vinay Sajip9828b7e2008-06-17 11:04:02 +00003141- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003142 environment to control the '-arch' flags that are used to build
3143 an extension. This was added for compatibility with Apple's build
3144 of Python.
3145
3146- The bundled OSX-specific copy of libbffi is now in sync with the version
3147 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
3148
Georg Brandl25c34082008-08-18 23:09:49 +00003149- The threading module gained aliases for names that will be removed in the

Brett Cannonb61d8012008-05-11 23:39:04 +00003159- ``Lib/lib-old`` is now added to sys.path.
3160
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003161- On MacOS X it is now possible to install the framework in 64-bit
3162 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003163 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003164
3165 This is controlled by the configure argument ``--with-universal-archs``:
3166
3167 - ``--with-universal-archs=all``: install 4-way universal
3168
3169 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3170
3171 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3172
3173 This option should be used in combination with ``--enable-universalsdk=``.
3174
3175 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 +00003225- Issue #1631171: Re-implement the 'warnings' module in C (the
3226 original Python code has been kept as backup). This will allow for
3227 using the 'warning's machinery in such places as the parser where
3228 use of pure Python code is not possible. Both the ``showarning()``
3229 and ``formatwarning()`` gain an optional 'line' argument which is
3230 not called by default for backwards-compatibility reasons. Setting
3231 ``warnings.showwarning()`` to an implementation that lacks support
3232 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003257- The getpass module has been improved on Unix. It now uses /dev/tty
3258 by default and uses stderr instead of stdout. A GetPassWarning is
3259 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003274- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003275 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Issue #2550: The approach used by client/server code for obtaining
3296 ports to listen on in network-oriented tests has been refined in an
3297 effort to facilitate running multiple instances of the entire
3298 regression test suite in parallel without issue.
3299 test_support.bind_port() has been fixed such that it will always
3300 return a unique port -- which wasn't always the case with the
3301 previous implementation, especially if socket options had been set
3302 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3303 new implementation of bind_port() will actually raise an exception
3304 if it is passed an AF_INET/SOCK_STREAM socket with either the
3305 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3306 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3307 the socket it's been passed. This currently only applies to
3308 Windows. This option prevents any other sockets from binding to the
3309 host/port we've bound to, thus removing the possibility of the
3310 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3311 when a second SOCK_STREAM socket binds and accepts to a host/port
3312 that's already been bound by another socket. The optional preferred
3313 port parameter to bind_port() has been removed. Under no
3314 circumstances should tests be hard coding ports!
3315
3316 test_support.find_unused_port() has also been introduced, which will
3317 pass a temporary socket object to bind_port() in order to obtain an
3318 unused port. The temporary socket object is then closed and
3319 deleted, and the port is returned. This method should only be used
3320 for obtaining an unused port in order to pass to an external program
3321 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3322 a parameter to a server-oriented class that doesn't give you direct
3323 access to the underlying socket used.
3324
3325 Finally, test_support.HOST has been introduced, which should be used
3326 for the host argument of any relevant socket calls (i.e. bind and
3327 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003328
3329 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003330 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003331 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3332 test_asynchat and test_socket_ssl.
3333
Georg Brandl3ee81df2008-05-17 18:14:43 +00003334 It is now possible for multiple instances of the regression test
3335 suite to run in parallel without issue.

3602-----------------
3603
Fred Drakea8ee94b2008-03-01 02:45:07 +00003604- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003605 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003610
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003611- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003612 issue 215555 for a discussion.
3613
Eric Smitha73fbe72008-02-23 03:09:44 +00003614- Added the future_builtins module, which contains hex() and oct().
3615 These are the PEP 3127 version of these functions, designed to be
3616 compatible with the hex() and oct() builtins from Python 3.0. They
3617 differ slightly in their output formats from the existing, unchanged
3618 Python 2.6 builtins. The expected usage of the future_builtins
3619 module is:
3620 from future_builtins import hex, oct
3621
Eric Smith7ef40bf2008-02-20 23:34:22 +00003622- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3623 exponents for exponents with absolute value < 100. Follows C99
3624 standard. This is a change on Windows, which would use 3 digits.
3625 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3626 so that any alterations it does to the resulting string will be
3627 available in stringlib/formatter.h (for float.__format__).
3628
Eric Smith5a3c1352008-02-19 13:21:56 +00003629- Implemented PEP 3101, Advanced String Formatting. This adds a new
3630 builtin format(); a format() method for str and unicode; a
3631 __format__() method to object, str, unicode, int, long, float, and
3632 datetime; the class string.Formatter; and the C API
3633 PyObject_Format().
3634
Georg Brandl3ee81df2008-05-17 18:14:43 +00003635- Fixed several potential crashes, all caused by specially crafted
3636 __del__ methods exploiting objects in temporarily inconsistent
3637 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003638
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003639- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003640 prevent a possible crash: an Abstract Base Class would try to access
3641 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003642

3644 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003646- Clear all free lists during a gc.collect() of the highest generation
3647 in order to allow pymalloc to free more arenas. Python may give back
3648 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003649
Georg Brandl3ee81df2008-05-17 18:14:43 +00003650- Issue #2045: Fix an infinite recursion triggered when printing a
3651 subclass of collections.defaultdict, if its default_factory is set
3652 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003653
Christian Heimesf75dbef2008-02-08 00:11:31 +00003654- Fixed a minor memory leak in dictobject.c. The content of the free
3655 list was not freed on interpreter shutdown.
3656
Georg Brandl3ee81df2008-05-17 18:14:43 +00003657- Limit free list of method and builtin function objects to 256
3658 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003659
Georg Brandl3ee81df2008-05-17 18:14:43 +00003660- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3661 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003662 to compact the internal free lists of pre-allocted ints and floats.
3663
Georg Brandl3ee81df2008-05-17 18:14:43 +00003664- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3665 calls. Python expected the return type int but the fork familie
3666 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003667
Georg Brandl3ee81df2008-05-17 18:14:43 +00003668- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3669 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003670
Georg Brandl3ee81df2008-05-17 18:14:43 +00003671- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3672 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003673
Georg Brandl3ee81df2008-05-17 18:14:43 +00003674- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3675 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003677- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3678 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003679
Georg Brandl3ee81df2008-05-17 18:14:43 +00003680- Patch #1473257: generator objects gain a gi_code attribute. This is
3681 the same object as the func_code attribute of the function that
3682 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003683
Georg Brandl3ee81df2008-05-17 18:14:43 +00003684- Issue #1920: "while 0" statements were completely removed by the
3685 compiler, even in the presence of an "else" clause, which is
3686 supposed to be run when the condition is false. Now the compiler
3687 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003688
Guido van Rossumeead05f2008-01-24 18:21:02 +00003689- A few crashers fixed: weakref_in_del.py (issue #1377858);
3690 loosing_dict_ref.py (issue #1303614, test67.py);
3691 borrowed_ref_[34].py (not in tracker).
3692
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003693- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003694 suppressed while an extension is loaded by calling SetErrorMode in
3695 dynload_win.c. The error is still reported properly.
3696
Georg Brandl3ee81df2008-05-17 18:14:43 +00003697- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003698 several extension methods and modules do not work without unicode
3699 support.
3700
Georg Brandl26543b12008-01-21 18:36:51 +00003701- Issue #1882: when compiling code from a string, encoding cookies in the
3702 second line of code were not always recognized correctly.
3703
Georg Brandl14404b62008-01-19 19:27:05 +00003704- Issue #1679: "0x" was taken as a valid integer literal.
3705
Georg Brandl6caad7d2008-01-26 14:19:22 +00003706- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003707 added.
3708
Christian Heimesc94e2b52008-01-14 04:13:37 +00003709- sys.float_info / PyFloat_GetInfo: The floating point information
3710 object was converted from a dict to a specialized structseq object.
3711
Georg Brandl3ee81df2008-05-17 18:14:43 +00003712- Patch #1816: Added sys.flags structseq. It exposes the status of
3713 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003714
Georg Brandl3ee81df2008-05-17 18:14:43 +00003715- Objects/structseq.c: Implemented new structseq representation. The
3716 patch makes structseqs (e.g. the return value of os.stat) more
3717 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003718
Georg Brandl3ee81df2008-05-17 18:14:43 +00003719- Patch #1700288: added a type attribute cache that caches method
3720 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003721
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003722- Bug #1776: __import__() no longer accepts filenames on any platform.
3723 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003724
Georg Brandlaed6c662008-01-07 17:25:53 +00003725- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3726
Georg Brandl3ee81df2008-05-17 18:14:43 +00003727- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3728 envvar and sys.dont_write_bytecode attribute. All these can be set
3729 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003730
Georg Brandl3ee81df2008-05-17 18:14:43 +00003731- Improve some exception messages when Windows fails to load an
3732 extension module. Now we get for example '%1 is not a valid Win32
3733 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003734

3738 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003739
Christian Heimes0a8143f2007-12-18 23:22:54 +00003740- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003741 and INF. float("nan"), float("inf") and float("-inf") now work on
3742 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003743
Georg Brandl3ee81df2008-05-17 18:14:43 +00003744- Compiler now generates simpler and faster code for dictionary
3745 literals. The oparg for BUILD_MAP now indicates an estimated
3746 dictionary size. There is a new opcode, STORE_MAP, for adding
3747 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003776- Patch #1739468: Directories and zipfiles containing a __main__.py
3777 file can now be directly executed by passing their name to the
3778 interpreter. The directory/zipfile is automatically inserted as the
3779 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003781- Issue #1265: Fix a problem with sys.settrace, if the tracing
3782 function uses a generator expression when at the same time the
3783 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003784
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003785- sets and frozensets now have an isdisjoint() method.
3786

3788
Neal Norwitz44f326e2007-10-05 05:29:17 +00003789- Fix warnings found by the new version of the Coverity checker.
3790
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791- The enumerate() builtin function is no longer bounded to sequences
3792 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3793 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003794
Georg Brandl3ee81df2008-05-17 18:14:43 +00003795- Issue #1686386: Tuple's tp_repr did not take into account the
3796 possibility of having a self-referential tuple, which is possible
3797 from C code. Nor did object's tp_str consider that a type's tp_str
3798 could do something that could lead to an inifinite recursion.
3799 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3800 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003801
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802- Issue #1164: It was possible to trigger deadlock when using the
3803 'print' statement to write to a file since the GIL was not released
3804 as needed. Now PyObject_Print() does the right thing along with
3805 various tp_print implementations of the built-in types and those in
3806 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003807
Georg Brandl3ee81df2008-05-17 18:14:43 +00003808- Issue #1147: Exceptions were directly allowing string exceptions in
3809 their throw() method even though string exceptions no longer
3810 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003815- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003816 PyObject_Call() never calling back out to Python code to trigger
3817 recursion depth updates/checks. Required the creation of a static
3818 RuntimeError instance in case normalizing an exception put the
3819 recursion check value past its limit. Fixes crashers
3820 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003821

Neal Norwitz0ac60192007-05-27 04:08:54 +00003835- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003836 __*__ attributes. (Some already existed, e.g., __doc__ and
3837 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003838
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003839- Add -3 option to the interpreter to warn about features that are
3840 deprecated and will be changed/removed in Python 3.0.
3841
Georg Brandl2134e752007-05-21 20:34:16 +00003842- Patch #1686487: you can now pass any mapping after '**' in function
3843 calls.
3844
Collin Winter62903052007-05-18 23:11:24 +00003845- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846 "except E as target:". This is to provide forwards compatibility
3847 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003848
Brett Cannon229cee22007-05-05 01:34:02 +00003849- Deprecate BaseException.message as per PEP 352.
3850
Georg Brandl3ee81df2008-05-17 18:14:43 +00003851- Issue #1303614: don't expose object's __dict__ when the dict is

3853
Vinay Sajip8549ce32007-05-06 17:53:37 +00003854- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003855 setting a plain string, ie don't expand to single letter identifiers.
3856
Raymond Hettinger13936692007-04-11 18:40:58 +00003857- Request #1191699: Slices can now be pickled.
3858
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003859- Request #1193128: str.translate() now allows a None argument for

3861 remaining characters.
3862
Georg Brandl5cb76c12007-03-21 09:00:39 +00003863- Patch #1682205: a TypeError while unpacking an iterable is no longer
3864 masked by a generic one with the message "unpack non-sequence".
3865
Neal Norwitzaa754b72007-03-21 06:39:48 +00003866- Remove unused file Python/fmod.c.
3867
Guido van Rossum143b5642007-03-23 04:58:42 +00003868- Bug #1683368: The object.__init__() and object.__new__() methods are
3869 now stricter in rejecting excess arguments. The only time when
3870 either allows excess arguments is when it is not overridden and the
3871 other one is. For backwards compatibility, when both are
3872 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003873 warning later). Also, type.__init__() insists on the same signature
3874 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003876- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3877 object to complex using its __complex__() method before falling back
3878 to the __float__() method. Therefore, the functions in the cmath
3879 module now can operate on objects that define a __complex__()
3880 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003881
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882- Patch #1623563: allow __class__ assignment for classes with

Georg Brandl871f1bc2007-03-12 13:17:36 +00003901- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003902 its argument, if it exists. If not, it will work like before. This
3903 allows customizing the output of dir() in the presence of a
3904 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003916- Patch #703779: unset __file__ in __main__ after running a file. This

3987 embedded in the string to convert.
3988

Georg Brandl3ee81df2008-05-17 18:14:43 +00004428 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004469 AttributeError instead of an IOError when the server's response
4470 didn't contain a valid HTTP status line.

Georg Brandl92a6bae2007-03-13 17:43:32 +00004503- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004504 are set for invalid interpolation sequences that would lead to

4561 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004954 time so that opening a database previously created with the DB_DUP
4955 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4956 opens. Specifically: dictionary assignment to a DB object will
4957 replace all values for a given key when the database allows
4958 duplicate values. DB users should use DB.put(k, v) when they want
4959 to store duplicates; not DB[k] = v.

4966 characters with ASCII value less than 32. Also, it correctly quotes
4967 dots only if they occur on a single line, as opposed to the previous
4968 behavior of quoting dots if they are the second character of any
4969 line.
