80 and read operations on write-only file objects. On Windows, the system C
81 library would return a bogus result; on Solaris, it was possible to crash
82 the interpreter. Patch by Stefan Krah.
83
Barry Warsawb1e66ee2010-02-05 18:45:25 +000084- Issue #7853: Normalize exceptions before they are passed to a context

114 some values large enough to cause overflow, and (4) a number of
115 flaws that could lead to incorrectly rounded results.
Mark Dickinson8efef5c2010-01-12 22:23:56 +0000116
Brett Cannon3ffa43d2010-01-14 20:00:28 +0000117- Issue #7319, #7770: Silence DeprecationWarning by default when -3 is not

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

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

Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000172- Issue #7748: Since unicode values are supported for some metadata options
173 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
174 encoded string for them. This ensure that the upload and register commands
175 send the right values to PyPI without any error.
176
R. David Murrayed44dfa2010-01-16 05:15:17 +0000177- Issue #1670765: Prevent email.generator.Generator from re-wrapping

257
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000258- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
259 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
260
Mark Dickinson1b34d252010-01-01 17:27:30 +0000261- Issue #5080: A number of functions and methods previously produced a
262 DeprecationWarning when passed a float argument where an integer was
263 expected. These functions and methods now raise TypeError instead.
264 The majority of the effects of this change are in the extension
265 modules, but some core functions and methods are affected: notably
266 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
267 methods.
268
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000269- Issue #7604: Deleting an unset slotted attribute did not raise an

277
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000278- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
279 used to drop the time part of the result.
280
Mark Dickinson46572832009-12-27 14:55:57 +0000281- Issue #1811: improve accuracy and cross-platform consistency for
282 true division of integers: the result of a/b is now correctly
283 rounded for ints a and b (at least on IEEE 754 platforms), and in
284 particular does not depend on the internal representation of a long.
285
Ezio Melottif84caf42009-12-24 22:25:17 +0000286- Issue #6108: unicode(exception) and str(exception) should return the same

288
Ronald Oussoren92919a62009-12-24 13:30:58 +0000289- Issue #6834: replace the implementation for the 'python' and 'pythonw'

433
Eric Smithc4ab8332009-11-29 17:40:57 +0000434- Issue #3382: 'F' formatting for float and complex now convert the
435 result to upper case. This only affects 'inf' and 'nan', since 'f'
436 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000437

442 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
443 requested 120 significant digits instead.
444

450 on MacOSX 10.6.
451
Mark Dickinsonb678de82009-11-19 18:41:49 +0000452- Issue #7117: repr(x) for a float x returns a result based on the
453 shortest decimal string that's guaranteed to round back to x under
454 correct rounding (with round-half-to-even rounding mode).
455 Previously it gave a string based on rounding x to 17 decimal digits.
456 repr(x) for a complex number behaves similarly. On platforms where
457 the correctly-rounded strtod and dtoa code is not supported (see below),
458 repr is unchanged.
459
460- Issue #7117: On almost all platforms: float-to-string and
461 string-to-float conversions within Python are now correctly rounded.
462 Places these conversions occur include: str for floats and complex
463 numbers; the float and complex constructors; old-style and new-style
464 numeric formatting; serialization and deserialization of floats and
465 complex numbers using marshal, pickle and json; parsing of float and
466 imaginary literals in Python code; Decimal-to-float conversion.
467
468 The conversions use a Python-adapted version of David Gay's
469 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
470 functions. This code is supported on Windows, and on Unix-like
471 platforms using gcc, icc or suncc as the C compiler. There may be a
472 small number of platforms on which correct operation of this code
473 cannot be guaranteed, so the code is not used: notably, this applies
474 to platforms where the C double format is not IEEE 754 binary64, and
475 to platforms on x86 hardware where the x87 FPU is set to 64-bit
476 precision and Python's configure script is unable to determine how
477 to change the FPU precision. On these platforms conversions use the
478 platform strtod and dtoa, as before.
479
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000480- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000481 now uses the correctly-rounded string <-> float conversions
482 described above (when available), and so produces correctly rounded
483 results that will display nicely under the float repr. There are
484 two related small changes: (1) round now accepts any class with an
485 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000486 floats for the second argument), and (2) an excessively large second
487 integer argument (e.g., round(1.234, 10**100)) no longer raises an
488 exception.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000616- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
617 statement and correctly lookup the __enter__ and __exit__ special methods.
618
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000619- Issue #5829: complex("1e500") no longer raises OverflowError. This
620 makes it consistent with float("1e500") and interpretation of real
621 and imaginary literals.
622
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000623- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
624
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000625- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
626 classes and instances.

R. David Murray525cffc2009-05-13 13:07:14 +0000628- Issue #5994: the marshal module now has docstrings.
629
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000630- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
631 (1) inf and nan strings with trailing whitespace were incorrectly
632 rejected; (2) parsing of strings representing infinities and nans
633 was locale aware; and (3) the interpretation of fromhex('-nan')
634 didn't match that of float('-nan').
635
Eric Smitha985a3a2009-05-05 18:26:08 +0000636- Issue #5920: For float.__format__, change the behavior with the
637 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
638 to be like 'g' but with at least one decimal point and with a
639 default precision of 12. Previously, the behavior the same but with
640 a default precision of 6. This more closely matches str(), and
641 reduces surprises when adding alignment flags to the empty
642 presentation type. This also affects the new complex.__format__ in
643 the same way.
644
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000645- Issue #5890: in subclasses of 'property' the __doc__ attribute was
646 shadowed by classtype's, even if it was None. property now
647 inserts the __doc__ into the subclass instance __dict__.
648
Antoine Pitrou653dece2009-05-04 18:32:32 +0000649- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
650 sequences. Patch by Nick Barnes and Victor Stinner.
651
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000652- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000653 format(complex(1, 2./3), '.5') now produces a sensible result.
654
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000655- Issue #5864: Fix empty format code formatting for floats so that it
656 never gives more than the requested number of significant digits.
657
Eric Smithcac7af62009-04-27 19:04:37 +0000658- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

662 titlecase, but not their own uppercase.
663
Eric Smith068f0652009-04-25 21:40:15 +0000664- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
665 _PyOS_double_to_string or PyOS_double_to_string.
666
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000667- Issue #5283: Setting __class__ in __del__ caused a segfault.
668
Mark Dickinson95bc9802009-04-24 12:46:53 +0000669- Issue #5816: complex(repr(z)) now recovers z exactly, even when
670 z involves nans, infs or negative zeros.
671
Eric Smithaca19e62009-04-22 13:29:05 +0000672- Implement PEP 378, Format Specifier for Thousands Separator, for
673 floats, ints, and longs.
674
675- Issue #5515: 'n' formatting for ints, longs, and floats handles
676 leading zero formatting poorly.
677
678- Issue #5772: For float.__format__, don't add a trailing ".0" if
679 we're using no type code and we have an exponent.
680
Mark Dickinson6736cf82009-04-20 21:13:33 +0000681- Issue #3166: Make long -> float (and int -> float) conversions
682 correctly rounded.
683
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000684- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
685 some builtin types.
686
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000687- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000688 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000689
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000690- Issue #5759: float() didn't call __float__ on str subclasses.
691
Georg Brandl3c4a5462009-04-12 12:08:12 +0000692- Issue #5704: the "-3" command-line option now implies "-t".
693
R. David Murray0374a822009-04-09 21:54:50 +0000694- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
695 its clarity and its speed.
696
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000697- Issue #2396: the memoryview object was backported from Python 3.1.
698

Brett Cannon15ba4da2009-04-01 18:03:59 +0000702- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
703
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000704- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
705 the end sys.path, for compatibility with the system install of Python.
706
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000707- Issue #4688: Add a heuristic so that tuples and dicts containing only
708 untrackable objects are not tracked by the garbage collector. This can
709 reduce the size of collections and therefore the garbage collection overhead
710 on long-running programs, depending on their particular use of datatypes.
711
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000712- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
713 improve its performance. Long divisions and remainder operations
714 are now between 50% and 150% faster.
715
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000716- Issue #4258: Make it possible to use base 2**30 instead of base
717 2**15 for the internal representation of integers, for performance
718 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
719 --enable-big-digits option to configure, which overrides the
720 default. Add sys.long_info structseq to provide information about
721 the internal format.
722
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000723- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
724 result traceback.__members__ no longer exists.)
725
Mark Dickinson6b265f12009-03-18 16:07:26 +0000726- Issue #4474: PyUnicode_FromWideChar now converts characters outside
727 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
728 and sizeof(Py_UNICODE) == 2.
729
Eric Smith6f42edb2009-03-14 11:57:26 +0000730- Issue #5237: Allow auto-numbered fields in str.format(). For
731 example: '{} {}'.format(1, 2) == '1 2'.
732
Brett Cannon6c4cff02009-03-11 04:51:06 +0000733- Issue #3652: Make the 'line' argument for warnings.showwarning() a
734 requirement. Means the DeprecationWarning from Python 2.6 can go away.
735
Eric Smithe9fb6862009-02-20 14:02:36 +0000736- Issue #5247: Improve error message when unknown format codes are
737 used when using str.format() with str, unicode, long, int, and
738 float arguments.
739
Raymond Hettinger08259e82009-02-18 23:10:19 +0000740- Running Python with the -3 option now also warns about classic division
741 for ints and longs.
742
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000743- Issue #5260: Long integers now consume less memory: average
744 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
745 on a 64-bit system.
746
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000747- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
748 rotating the object pointer by 4 bits to the right.
749
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000750- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
751 it now forces its argument to double before testing for infinity.
752
Benjamin Petersone18ef192009-01-20 14:21:16 +0000753- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
754
Georg Brandl29c6a282009-04-05 20:23:13 +0000755- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000756 were suppressing all exceptions. These include list(), filter(), map(),
757 zip(), and bytearray().
758
Benjamin Peterson596d3062009-01-19 15:42:23 +0000759- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
760 functions.
761
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000762- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

766
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000767- Issue #4935: The overflow checking code in the expandtabs() method common
768 to str, bytes and bytearray could be optimized away by the compiler, letting
769 the interpreter segfault instead of raising an error.
770
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000771- Issue #3720: Fix a crash when an iterator modifies its class and removes its
772 __next__ method.

777
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000778- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
779 collecting the oldest generation) so that allocating lots of objects without
780 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000781 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000782 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

785
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000786- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
787 an existing .py counterpart, override the co_filename attributes of all
788 code objects if the original filename is obsolete (which can happen if the
789 file has been renamed, moved, or if it is accessed through different paths).
790 Patch by Ziga Seilnacht and Jean-Paul Calderone.
791
Martin v. Löwis5344c992009-01-02 20:32:55 +0000792- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000794- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
795 file with `str' filename on Windows.
796
Antoine Pitrouaa687902009-01-01 14:11:22 +0000797- Issue #3680: Reference cycles created through a dict, set or deque iterator
798 did not get collected.
799
Nick Coghlan180e4002008-12-30 01:18:48 +0000800- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
801 where the tp_hash and tp_dict slots are both NULL.
802
Benjamin Peterson7af65562008-12-29 17:56:58 +0000803- Issue #4764: With io.open, IOError.filename is set when trying to open a
804 directory on POSIX systems.
805
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000806- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
807 systems.
808
Georg Brandl6425a2f2008-12-28 11:54:53 +0000809- Issue #4759: None is now allowed as the first argument of
810 bytearray.translate(). It was always allowed for bytes.translate().
811
Skip Montanarof205c132008-12-23 03:30:15 +0000812- Added test case to ensure attempts to read from a file opened for writing
813 fail.
814
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000815- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
816 print elapsed times, not only when some objects are uncollectable /
817 unreachable. Original patch by Neil Schemenauer.
818
Mark Dickinson1a707982008-12-17 16:14:37 +0000819- Issue #3439: Add a bit_length method to int and long.

Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000824- Issue #4597: Fixed exception handling when the __exit__ function of a
825 context manager returns a value that cannot be converted to a bool.
826
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000827- Issue #4597: Fixed several opcodes that weren't always propagating
828 exceptions.
829
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000830- Issue #4445: Replace "sizeof(PyStringObject)" with
831 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
832 str instances. On a typical machine this saves 3 bytes of memory
833 (on average) per string allocation.
834
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000835- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
836 interpreter to abort ("Fatal Python error: Could not reset the stack!")
837 instead of throwing a MemoryError.
838
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000839- Issue #3689: The list reversed iterator now supports __length_hint__
840 instead of __len__. Behavior now matches other reversed iterators.
841
Benjamin Petersonc078f922008-11-21 22:27:24 +0000842- Issue #4367: Python would segfault during compiling when the unicodedata
843 module couldn't be imported and \N escapes were present.
844
Vinay Sajip213faca2008-12-03 23:22:58 +0000845- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000846 method on file objects with closefd=False. The file descriptor is still
847 kept open but the file object behaves like a closed file. The ``FileIO``
848 object also got a new readonly attribute ``closefd``.
849
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000850- Issue #4348: Some bytearray methods returned that didn't cause any change to
851 the bytearray, returned the same bytearray instead of a copy.
852
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000853- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

856
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000857- Issue #4048: The parser module now correctly validates relative imports.
858
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000859- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
860 exec statement.
861
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000862- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
863 method does not return iterators for the 4th and 5th items.
864
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000865- Issue #4209: Enabling unicode_literals and the print_function in the same
866 __future__ import didn't work.
867
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000868- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000869 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000870
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000871- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
872 returned a path longer than MAX_PATH. (But It's doubtful this code path is
873 really executed because I cannot move to such directory on win2k)
874
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000875- Issue #4069: When set.remove(element) is used with a set element, the element
876 is temporarily replaced with an equivalent frozenset. But the eventual
877 KeyError would always report the empty frozenset([]) as the missing key. Now
878 it correctly refers to the initial element.
879
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000880- Issue #4509: Various issues surrounding resize of bytearray objects to

896 returned them on 64bit platforms.
897
Walter Dörwalded960ac2009-05-03 22:36:33 +0000898- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
899 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
900 step. This avoids problems with counting UTF-8 bytes that ignores the effect
901 of using the replace error handler in PyUnicode_DecodeUTF8().
902
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000903- Issue #3739: The unicode-internal encoder now reports the number of characters
904 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000906- Issue #2422: When compiled with the ``--with-valgrind`` option, the
907 pymalloc allocator will be automatically disabled when running under
908 Valgrind. This gives improved memory leak detection when running
909 under Valgrind, while taking advantage of pymalloc at other times.

Michael Foord07ef4872009-05-02 22:43:34 +00001445- Issue #5679: The methods unittest.TestCase.addCleanup and doCleanups were added.
1446 addCleanup allows you to add cleanup functions that will be called
1447 unconditionally (after setUp if setUp fails, otherwise after tearDown). This
1448 allows for much simpler resource allocation and deallocation during tests.
1449
1450- Issue #3379: unittest.main now takes an optional exit argument. If False main
1451 doesn't call sys.exit allowing it to be used from the interactive interpreter.

1461
Michael Foord345b2fe2009-04-02 03:20:38 +00001462- Issue #5663: better failure messages for unittest asserts. Default assertTrue
1463 and assertFalse messages are now useful. TestCase has a longMessage attribute.
1464 This defaults to False, but if set to True useful error messages are shown in
1465 addition to explicit messages passed to assert methods.

1475 instead of performing them in functions. Helps prevent import deadlocking in
1476 threads.
1477
Raymond Hettinger66c4a6b2009-04-01 18:50:56 +00001478- Issue #5647: MutableSet.__iand__() no longer mutates self during iteration.

1505
Guilherme Polo1972d162009-03-27 21:43:08 +00001506- Adjusted _tkinter to compile without warnings when WITH_THREAD is not

1516 not given a callable so that code to be tested can be written inline using
1517 a with statement.
1518
1519- The unittest.TestCase.assertEqual() now displays the differences in lists,
1520 tuples, dicts and sets on failure. Many new handy type and comparison

2146 leak-chasing test runs give sensible results. The previous method of
2147 reaping threads could return successfully while some Thread objects were

2176 test_heapq and test_warnings have been adjusted to use it, tests for
2177 other modules with both C and Python implementations in the stdlib

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00002270 AttributeError instead of RuntimeError, depending in which C API call
2271 exactly the recursion limit is exceeded. Consequently, both exception types
2272 are caught and silenced.

2288
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002289- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2290
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002291- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2292 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2293 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2294 ``printf`` function, whereas PyString_FromFormat has an independent
2295 implementation and uses "%zd" on all platforms for size_t values.
2296 This makes a difference on win64, where ``printf`` needs "%Id" to display
2297 64bit values.
2298
Benjamin Peterson97179b02008-09-09 20:55:01 +00002299- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2300 error.
2301
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002302- Issue #3777: long() applied to a float object now always return a long
2303 object; previously an int would be returned for small values. the __long__
2304 method is allowed to return either an int or a long, but the behaviour of
2305 float objects should not change to respect backward compatibility.
2306
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002307- Issue #3751: str.rpartition would perform a left-partition when called with
2308 a unicode argument.
2309
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002310- Issue #3683: Fix compilation when --without-threads is given.
2311
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002312- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002313 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002314 was correctly parsed but parsing of subsequent arguments failed.
2315
Vinay Sajip35e3b032008-09-01 14:33:59 +00002316- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002317 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2318 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2319 when given a tuple of classes as second argument, were looking up
2320 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2321 type object.
2322
Neal Norwitz18aa3882008-08-24 05:04:52 +00002323- Fix crashes on memory allocation failure found with failmalloc.
2324
2325- Fix memory leaks found with valgrind and update suppressions file.
2326
2327- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2328
2329- Fix problem using wrong name in decimal module reported by pychecker.
2330
Christian Heimes7d4c3172008-08-22 19:47:25 +00002331- Silenced another compiler warning about a used but not defined
2332 function 'stringlib_contains_obj'.
2333
Benjamin Peterson712ee922008-08-24 18:10:20 +00002334- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2335 ``__delslice__``.
2336
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002337- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2338 library targets in the Makefile.
2339
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002340- Issue #1204: The configure script now tests for additional libraries
2341 that may be required when linking against readline. This fixes issues
2342 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00002365- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002366 return a list or None rather than a custom object.
2367
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002368- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2392 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2393 for catch_warnings() also led to an improvement in the raising of a
2394 DeprecationWarning related to warnings.warn_explicit().
2395
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002396- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002460What's New in Python 2.6 beta 3?
2461================================
2462
Barry Warsaw07a4a382008-08-21 01:15:08 +00002463*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002464
2465Core and Builtins
2466-----------------
2467
Guido van Rossumf8402962008-08-20 15:01:50 +00002468- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2469 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2470 extensions do not automatically benefit from the class attribute
2471 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2472 to their tp_flags field if they care. This is a backwards
2473 compatibility feature; in 3.0, all types will use the cache by
2474 default.
2475
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002476- Keyword arguments can now follow starred arguments. (``f(a, *args,
2477 keyword=23)`` is now valid syntax.)
2478
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002479- ctypes function pointers that are COM methods have a boolean True
2480 value again.
2481
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002482- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2483 by denying s# to parse objects that have a releasebuffer procedure,
2484 and introducing s*.
2485
Georg Brandl1e13ea92008-08-11 09:07:59 +00002486- Issue #3537: Fix an assertion failure when an empty but presized dict
2487 object was stored in the freelist.
2488
Mark Dickinsonb6467572008-08-04 21:30:09 +00002489- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2490 ValueError consistently across platforms.
2491
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002492- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2493 (64bit Unix, for example), unichr() would truncate its argument and return
2494 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2495
Neal Norwitze7d8be82008-07-31 17:17:14 +00002496- Apply security patches from Apple.
2497
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002498- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2499 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2500
Antoine Pitrou92f82162008-07-25 22:22:08 +00002501- Issue #1819: function calls with several named parameters are now on
2502 average 35% faster (as measured by pybench).
2503
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002504- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2505 the python debugger steps into a class statement: the free variables (local
2506 variables defined in an outer scope) would be deleted from the outer scope.
2507
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002508- Issue #2620: Overflow checking when allocating or reallocating memory
2509 was not always being done properly in some python types and extension
2510 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2511 all been updated to perform better checks and places in the code that
2512 would previously leak memory on the error path when such an allocation
2513 failed have been fixed.

2517
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002518- Issue #3612: Added some missing basic types in ctypes.wintypes.
2519
Benjamin Petersone977ad42008-08-20 01:42:01 +00002520- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2521 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2522
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002523- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2524 version reported by these tools does not necessarily follow the python
2525 version numbering scheme, so the module is less strict when parsing it.
2526
Nick Coghlanf70385a2008-08-18 12:42:46 +00002527- Issue #2235: Added Py3k warnings for types which will become unhashable
2528 under the stricter __hash__ inheritance rules in 3.0. Several types
2529 which did not meet the rules for hash invariants and were already
2530 unhashable in 3.0 have now been explicitly flagged as unhashable in
2531 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2532 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2533
Brett Cannon88f801d2008-08-18 00:46:22 +00002534- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2535 imported into the module but exposed as part of the module's API.
2536
Brett Cannon7b96f072008-08-18 00:41:11 +00002537- Remove an unneeded import of abc.ABCMeta from 'inspect'.

2542
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002543- Issue #3575: Incremental decoder's decode function now takes bytearray
2544 by using 's*' instead of 't#'.
2545
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002546- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002547 fails unicode conversion on 2nd parameter. (windows only)
2548
Facundo Batista94f243a2008-08-17 03:38:39 +00002549- Issue 2464. urllib2 now supports a malformation in the URL received
2550 in a redirect.
2551
Brett Cannonabe423e2008-08-16 21:47:07 +00002552- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002553 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002554
Facundo Batistaeb90b782008-08-16 14:44:07 +00002555- Issue #2776: fixed small issue when handling an URL with double slash
2556 after a 302 response in the case of not going through a proxy.
2557
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002558- Issue #2676: in the email package, content-type parsing was hanging on
2559 pathological input because of quadratic or exponential behaviour of a

Antoine Pitroude781a42008-08-09 12:43:23 +00002603 asking for a specific length. This problem only affected files opened
2604 using the new "io" module, not the built-in open() function.

2647
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002648- Issue #643841: The language reference now provides more detailed

2660-----------------
2661
Georg Brandl3e483f62008-07-16 22:57:41 +00002662- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2663 its methods now allow for items objects that can be converted to
2664 an integer using operator.index().
2665
Mark Dickinson64b7e502008-07-16 09:40:03 +00002666- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2667 produced a ValueError instead of giving the correct float.
2668
Eric Smitha5fa5a22008-07-16 00:11:49 +00002669- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2670 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2671
Mark Dickinson7103aa42008-07-15 19:08:33 +00002672- Issue #3008: the float type has a new instance method 'float.hex'
2673 and a new class method 'float.fromhex' to convert floating-point
2674 numbers to and from hexadecimal strings, respectively.
2675
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002676- Issue #2235: __hash__ is once again inherited by default. To allow
2677 collections.Hashable to remain meaningful in the presence of the
2678 default hash implementation (object.__hash__), it is now possible
2679 to explicit block inheritance of hash by setting __hash__=None at
2680 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2681 level.
2682
Nick Coghlanb028f502008-07-13 14:52:36 +00002683- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2684 the parent module cannot be found while performing an absolute import.
2685 This means that an incorrectly defined __package__ attribute will
2686 now only prevent relative imports in that module rather than causing
2687 all imports from that module to fail.
2688
Nick Coghlan14ff9942008-07-08 14:21:42 +00002689- Issue #2517: Allow unicode messages in Exceptions again by correctly

2699 another thread's dictionary.
2700
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002701- Issue #3004: Minor change to slice.indices(): the start and stop
2702 arguments are now treated identically, making the behaviour easier
2703 to describe and understand. For example, slice(None, -10,
2704 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2705 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2706 10, -1).
2707
Georg Brandl278fc502008-07-19 12:46:12 +00002708- Issue #3219: Calling a function with repeated keyword arguments,
2709 f(a=2, a=23), would not cause a syntax error. This was a regression
2710 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002711
Georg Brandl278fc502008-07-19 12:46:12 +00002712- Issue #2862: Make int and float freelist management consistent with
2713 other freelists. Changes their CompactFreeList apis into

2720 api functions without holding the GIL, which could lead to a fatal
2721 error when they failed.
2722
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002723- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002748- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2749 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002750 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002751 content-length. The problem had been corrected in the 2.4 branch, but never
2752 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002767- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2769
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002770- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Benjamin Peterson23681932008-05-12 21:42:13 +00003137
Vinay Sajip9828b7e2008-06-17 11:04:02 +00003138- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003139 environment to control the '-arch' flags that are used to build
3140 an extension. This was added for compatibility with Apple's build
3141 of Python.
3142
3143- The bundled OSX-specific copy of libbffi is now in sync with the version
3144 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
3145
Georg Brandl25c34082008-08-18 23:09:49 +00003146- The threading module gained aliases for names that will be removed in the

3155
Brett Cannonb61d8012008-05-11 23:39:04 +00003156- ``Lib/lib-old`` is now added to sys.path.
3157
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003158- On MacOS X it is now possible to install the framework in 64-bit
3159 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003160 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003161
3162 This is controlled by the configure argument ``--with-universal-archs``:
3163
3164 - ``--with-universal-archs=all``: install 4-way universal
3165
3166 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3167
3168 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3169
3170 This option should be used in combination with ``--enable-universalsdk=``.
3171
3172 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 +00003222- Issue #1631171: Re-implement the 'warnings' module in C (the
3223 original Python code has been kept as backup). This will allow for
3224 using the 'warning's machinery in such places as the parser where
3225 use of pure Python code is not possible. Both the ``showarning()``
3226 and ``formatwarning()`` gain an optional 'line' argument which is
3227 not called by default for backwards-compatibility reasons. Setting
3228 ``warnings.showwarning()`` to an implementation that lacks support
3229 for the ``line`` argument will raise a DeprecationWarning.

3253
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003254- The getpass module has been improved on Unix. It now uses /dev/tty
3255 by default and uses stderr instead of stdout. A GetPassWarning is
3256 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003257

Georg Brandl3ee81df2008-05-17 18:14:43 +00003271- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003272 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003292- Issue #2550: The approach used by client/server code for obtaining
3293 ports to listen on in network-oriented tests has been refined in an
3294 effort to facilitate running multiple instances of the entire
3295 regression test suite in parallel without issue.
3296 test_support.bind_port() has been fixed such that it will always
3297 return a unique port -- which wasn't always the case with the
3298 previous implementation, especially if socket options had been set
3299 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3300 new implementation of bind_port() will actually raise an exception
3301 if it is passed an AF_INET/SOCK_STREAM socket with either the
3302 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3303 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3304 the socket it's been passed. This currently only applies to
3305 Windows. This option prevents any other sockets from binding to the
3306 host/port we've bound to, thus removing the possibility of the
3307 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3308 when a second SOCK_STREAM socket binds and accepts to a host/port
3309 that's already been bound by another socket. The optional preferred
3310 port parameter to bind_port() has been removed. Under no
3311 circumstances should tests be hard coding ports!
3312
3313 test_support.find_unused_port() has also been introduced, which will
3314 pass a temporary socket object to bind_port() in order to obtain an
3315 unused port. The temporary socket object is then closed and
3316 deleted, and the port is returned. This method should only be used
3317 for obtaining an unused port in order to pass to an external program
3318 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3319 a parameter to a server-oriented class that doesn't give you direct
3320 access to the underlying socket used.
3321
3322 Finally, test_support.HOST has been introduced, which should be used
3323 for the host argument of any relevant socket calls (i.e. bind and
3324 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003325
3326 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003327 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003328 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3329 test_asynchat and test_socket_ssl.
3330
Georg Brandl3ee81df2008-05-17 18:14:43 +00003331 It is now possible for multiple instances of the regression test
3332 suite to run in parallel without issue.

3600
Fred Drakea8ee94b2008-03-01 02:45:07 +00003601- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003602 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003608- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003609 issue 215555 for a discussion.
3610
Eric Smitha73fbe72008-02-23 03:09:44 +00003611- Added the future_builtins module, which contains hex() and oct().
3612 These are the PEP 3127 version of these functions, designed to be
3613 compatible with the hex() and oct() builtins from Python 3.0. They
3614 differ slightly in their output formats from the existing, unchanged
3615 Python 2.6 builtins. The expected usage of the future_builtins
3616 module is:
3617 from future_builtins import hex, oct
3618
Eric Smith7ef40bf2008-02-20 23:34:22 +00003619- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3620 exponents for exponents with absolute value < 100. Follows C99
3621 standard. This is a change on Windows, which would use 3 digits.
3622 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3623 so that any alterations it does to the resulting string will be
3624 available in stringlib/formatter.h (for float.__format__).
3625
Eric Smith5a3c1352008-02-19 13:21:56 +00003626- Implemented PEP 3101, Advanced String Formatting. This adds a new
3627 builtin format(); a format() method for str and unicode; a
3628 __format__() method to object, str, unicode, int, long, float, and
3629 datetime; the class string.Formatter; and the C API
3630 PyObject_Format().
3631
Georg Brandl3ee81df2008-05-17 18:14:43 +00003632- Fixed several potential crashes, all caused by specially crafted
3633 __del__ methods exploiting objects in temporarily inconsistent
3634 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003635
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003636- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003637 prevent a possible crash: an Abstract Base Class would try to access
3638 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003639

3641 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003643- Clear all free lists during a gc.collect() of the highest generation
3644 in order to allow pymalloc to free more arenas. Python may give back
3645 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003646
Georg Brandl3ee81df2008-05-17 18:14:43 +00003647- Issue #2045: Fix an infinite recursion triggered when printing a
3648 subclass of collections.defaultdict, if its default_factory is set
3649 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003650
Christian Heimesf75dbef2008-02-08 00:11:31 +00003651- Fixed a minor memory leak in dictobject.c. The content of the free
3652 list was not freed on interpreter shutdown.
3653
Georg Brandl3ee81df2008-05-17 18:14:43 +00003654- Limit free list of method and builtin function objects to 256
3655 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003656
Georg Brandl3ee81df2008-05-17 18:14:43 +00003657- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3658 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003659 to compact the internal free lists of pre-allocted ints and floats.
3660
Georg Brandl3ee81df2008-05-17 18:14:43 +00003661- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3662 calls. Python expected the return type int but the fork familie
3663 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003664
Georg Brandl3ee81df2008-05-17 18:14:43 +00003665- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3666 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003667
Georg Brandl3ee81df2008-05-17 18:14:43 +00003668- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3669 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003670
Georg Brandl3ee81df2008-05-17 18:14:43 +00003671- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3672 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003673
Georg Brandl3ee81df2008-05-17 18:14:43 +00003674- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3675 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003676
Georg Brandl3ee81df2008-05-17 18:14:43 +00003677- Patch #1473257: generator objects gain a gi_code attribute. This is
3678 the same object as the func_code attribute of the function that
3679 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003680
Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- Issue #1920: "while 0" statements were completely removed by the
3682 compiler, even in the presence of an "else" clause, which is
3683 supposed to be run when the condition is false. Now the compiler
3684 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003685
Guido van Rossumeead05f2008-01-24 18:21:02 +00003686- A few crashers fixed: weakref_in_del.py (issue #1377858);
3687 loosing_dict_ref.py (issue #1303614, test67.py);
3688 borrowed_ref_[34].py (not in tracker).
3689
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003690- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003691 suppressed while an extension is loaded by calling SetErrorMode in
3692 dynload_win.c. The error is still reported properly.
3693
Georg Brandl3ee81df2008-05-17 18:14:43 +00003694- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003695 several extension methods and modules do not work without unicode
3696 support.
3697
Georg Brandl26543b12008-01-21 18:36:51 +00003698- Issue #1882: when compiling code from a string, encoding cookies in the
3699 second line of code were not always recognized correctly.
3700
Georg Brandl14404b62008-01-19 19:27:05 +00003701- Issue #1679: "0x" was taken as a valid integer literal.
3702
Georg Brandl6caad7d2008-01-26 14:19:22 +00003703- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003704 added.
3705
Christian Heimesc94e2b52008-01-14 04:13:37 +00003706- sys.float_info / PyFloat_GetInfo: The floating point information
3707 object was converted from a dict to a specialized structseq object.
3708
Georg Brandl3ee81df2008-05-17 18:14:43 +00003709- Patch #1816: Added sys.flags structseq. It exposes the status of
3710 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003711
Georg Brandl3ee81df2008-05-17 18:14:43 +00003712- Objects/structseq.c: Implemented new structseq representation. The
3713 patch makes structseqs (e.g. the return value of os.stat) more
3714 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003715
Georg Brandl3ee81df2008-05-17 18:14:43 +00003716- Patch #1700288: added a type attribute cache that caches method
3717 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003718
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003719- Bug #1776: __import__() no longer accepts filenames on any platform.
3720 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003721
Georg Brandlaed6c662008-01-07 17:25:53 +00003722- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3723
Georg Brandl3ee81df2008-05-17 18:14:43 +00003724- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3725 envvar and sys.dont_write_bytecode attribute. All these can be set
3726 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003727
Georg Brandl3ee81df2008-05-17 18:14:43 +00003728- Improve some exception messages when Windows fails to load an
3729 extension module. Now we get for example '%1 is not a valid Win32
3730 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003731

3735 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003736
Christian Heimes0a8143f2007-12-18 23:22:54 +00003737- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003738 and INF. float("nan"), float("inf") and float("-inf") now work on
3739 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003740
Georg Brandl3ee81df2008-05-17 18:14:43 +00003741- Compiler now generates simpler and faster code for dictionary
3742 literals. The oparg for BUILD_MAP now indicates an estimated
3743 dictionary size. There is a new opcode, STORE_MAP, for adding
3744 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003745

Georg Brandl3ee81df2008-05-17 18:14:43 +00003773- Patch #1739468: Directories and zipfiles containing a __main__.py
3774 file can now be directly executed by passing their name to the
3775 interpreter. The directory/zipfile is automatically inserted as the
3776 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003777
Georg Brandl3ee81df2008-05-17 18:14:43 +00003778- Issue #1265: Fix a problem with sys.settrace, if the tracing
3779 function uses a generator expression when at the same time the
3780 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003781
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003782- sets and frozensets now have an isdisjoint() method.
3783

3785
Neal Norwitz44f326e2007-10-05 05:29:17 +00003786- Fix warnings found by the new version of the Coverity checker.
3787
Georg Brandl3ee81df2008-05-17 18:14:43 +00003788- The enumerate() builtin function is no longer bounded to sequences
3789 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3790 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003791
Georg Brandl3ee81df2008-05-17 18:14:43 +00003792- Issue #1686386: Tuple's tp_repr did not take into account the
3793 possibility of having a self-referential tuple, which is possible
3794 from C code. Nor did object's tp_str consider that a type's tp_str
3795 could do something that could lead to an inifinite recursion.
3796 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3797 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003798
Georg Brandl3ee81df2008-05-17 18:14:43 +00003799- Issue #1164: It was possible to trigger deadlock when using the
3800 'print' statement to write to a file since the GIL was not released
3801 as needed. Now PyObject_Print() does the right thing along with
3802 various tp_print implementations of the built-in types and those in
3803 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003804
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- Issue #1147: Exceptions were directly allowing string exceptions in
3806 their throw() method even though string exceptions no longer
3807 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003808
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00003811
Brett Cannon1e534b52007-09-07 04:18:30 +00003812- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003813 PyObject_Call() never calling back out to Python code to trigger
3814 recursion depth updates/checks. Required the creation of a static
3815 RuntimeError instance in case normalizing an exception put the
3816 recursion check value past its limit. Fixes crashers
3817 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003818

Neal Norwitz0ac60192007-05-27 04:08:54 +00003832- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003833 __*__ attributes. (Some already existed, e.g., __doc__ and
3834 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003835
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003836- Add -3 option to the interpreter to warn about features that are
3837 deprecated and will be changed/removed in Python 3.0.
3838
Georg Brandl2134e752007-05-21 20:34:16 +00003839- Patch #1686487: you can now pass any mapping after '**' in function
3840 calls.
3841
Collin Winter62903052007-05-18 23:11:24 +00003842- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003843 "except E as target:". This is to provide forwards compatibility
3844 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003845
Brett Cannon229cee22007-05-05 01:34:02 +00003846- Deprecate BaseException.message as per PEP 352.
3847
Georg Brandl3ee81df2008-05-17 18:14:43 +00003848- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003849 inherited from a builtin base.
3850
Vinay Sajip8549ce32007-05-06 17:53:37 +00003851- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003852 setting a plain string, ie don't expand to single letter identifiers.
3853
Raymond Hettinger13936692007-04-11 18:40:58 +00003854- Request #1191699: Slices can now be pickled.
3855
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003856- Request #1193128: str.translate() now allows a None argument for
3857 translations that only remove characters without re-mapping the
3858 remaining characters.
3859
Georg Brandl5cb76c12007-03-21 09:00:39 +00003860- Patch #1682205: a TypeError while unpacking an iterable is no longer
3861 masked by a generic one with the message "unpack non-sequence".
3862
Neal Norwitzaa754b72007-03-21 06:39:48 +00003863- Remove unused file Python/fmod.c.
3864
Guido van Rossum143b5642007-03-23 04:58:42 +00003865- Bug #1683368: The object.__init__() and object.__new__() methods are
3866 now stricter in rejecting excess arguments. The only time when
3867 either allows excess arguments is when it is not overridden and the
3868 other one is. For backwards compatibility, when both are
3869 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003870 warning later). Also, type.__init__() insists on the same signature
3871 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3874 object to complex using its __complex__() method before falling back
3875 to the __float__() method. Therefore, the functions in the cmath
3876 module now can operate on objects that define a __complex__()
3877 method.

3897
Georg Brandl871f1bc2007-03-12 13:17:36 +00003898- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003899 its argument, if it exists. If not, it will work like before. This
3900 allows customizing the output of dir() in the presence of a
3901 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003913- Patch #703779: unset __file__ in __main__ after running a file. This

3984 embedded in the string to convert.
3985

Georg Brandl3ee81df2008-05-17 18:14:43 +00004425 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004466 AttributeError instead of an IOError when the server's response
4467 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004951 time so that opening a database previously created with the DB_DUP
4952 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4953 opens. Specifically: dictionary assignment to a DB object will
4954 replace all values for a given key when the database allows
4955 duplicate values. DB users should use DB.put(k, v) when they want
4956 to store duplicates; not DB[k] = v.

4965 behavior of quoting dots if they are the second character of any
4966 line.
