83 is run with the -OO flag. Tests requiring docstrings are skipped.
84
Ezio Melotti8f6a2872010-02-10 21:40:33 +000085- Issue #7712: test_support gained a new `temp_cwd` context manager which is

105 and read operations on write-only file objects. On Windows, the system C
106 library would return a bogus result; on Solaris, it was possible to crash
107 the interpreter. Patch by Stefan Krah.
108
Barry Warsawb1e66ee2010-02-05 18:45:25 +0000109- Issue #7853: Normalize exceptions before they are passed to a context

123 suite_mask, and product_type.
124
Antoine Pitroue80a6a42010-01-17 12:26:20 +0000125- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
126 could crash in many places because of the PyByteArray_AS_STRING() macro

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

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

170 specified, rather than fall through to AF_PACKET (in the `socket` module).
171 Also, raise ValueError rather than TypeError when an unknown TIPC address
172 type is specified. Patch by Brian Curtin.
173
Vinay Sajip28c382f2010-02-04 18:48:53 +0000174- logging: Implemented PEP 391.

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

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

Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000197- Issue #7748: Since unicode values are supported for some metadata options
198 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
199 encoded string for them. This ensure that the upload and register commands
200 send the right values to PyPI without any error.
201
R. David Murrayed44dfa2010-01-16 05:15:17 +0000202- Issue #1670765: Prevent email.generator.Generator from re-wrapping

Benjamin Petersonecdae192010-01-04 00:43:01 +0000280- The __complex__ method is now looked up on the class of instances to make it
281 consistent with other special methods.
282
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000283- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
284 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
285
Mark Dickinson1b34d252010-01-01 17:27:30 +0000286- Issue #5080: A number of functions and methods previously produced a
287 DeprecationWarning when passed a float argument where an integer was
288 expected. These functions and methods now raise TypeError instead.
289 The majority of the effects of this change are in the extension
290 modules, but some core functions and methods are affected: notably
291 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
292 methods.
293
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000294- Issue #7604: Deleting an unset slotted attribute did not raise an
295 AttributeError.

298 negative zero) in ** operator. The behaviour now conforms to that
299 described in C99 Annex F.
300
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +0000301- Issue #7579: the msvcrt module now has docstrings for all its functions.
302
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000303- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
304 used to drop the time part of the result.
305
Mark Dickinson46572832009-12-27 14:55:57 +0000306- Issue #1811: improve accuracy and cross-platform consistency for
307 true division of integers: the result of a/b is now correctly
308 rounded for ints a and b (at least on IEEE 754 platforms), and in
309 particular does not depend on the internal representation of a long.
310
Ezio Melottif84caf42009-12-24 22:25:17 +0000311- Issue #6108: unicode(exception) and str(exception) should return the same

313
Ronald Oussoren92919a62009-12-24 13:30:58 +0000314- Issue #6834: replace the implementation for the 'python' and 'pythonw'
315 executables on OSX.
316

461 no longer converts to 'g' for large values.

476
Mark Dickinsonb678de82009-11-19 18:41:49 +0000477- Issue #7117: repr(x) for a float x returns a result based on the
478 shortest decimal string that's guaranteed to round back to x under
479 correct rounding (with round-half-to-even rounding mode).
480 Previously it gave a string based on rounding x to 17 decimal digits.
481 repr(x) for a complex number behaves similarly. On platforms where
482 the correctly-rounded strtod and dtoa code is not supported (see below),
483 repr is unchanged.
484
485- Issue #7117: On almost all platforms: float-to-string and
486 string-to-float conversions within Python are now correctly rounded.
487 Places these conversions occur include: str for floats and complex
488 numbers; the float and complex constructors; old-style and new-style
489 numeric formatting; serialization and deserialization of floats and
490 complex numbers using marshal, pickle and json; parsing of float and
491 imaginary literals in Python code; Decimal-to-float conversion.
492
493 The conversions use a Python-adapted version of David Gay's
494 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
495 functions. This code is supported on Windows, and on Unix-like
496 platforms using gcc, icc or suncc as the C compiler. There may be a
497 small number of platforms on which correct operation of this code
498 cannot be guaranteed, so the code is not used: notably, this applies
499 to platforms where the C double format is not IEEE 754 binary64, and
500 to platforms on x86 hardware where the x87 FPU is set to 64-bit
501 precision and Python's configure script is unable to determine how
502 to change the FPU precision. On these platforms conversions use the
503 platform strtod and dtoa, as before.
504
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000505- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000506 now uses the correctly-rounded string <-> float conversions
507 described above (when available), and so produces correctly rounded
508 results that will display nicely under the float repr. There are
509 two related small changes: (1) round now accepts any class with an
510 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000511 floats for the second argument), and (2) an excessively large second
512 integer argument (e.g., round(1.234, 10**100)) no longer raises an
513 exception.

Raymond Hettinger62641e92009-06-23 20:59:43 +0000619- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
620 because it wasn't recognized as a sequence).
621
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +0000622- Issue #6289: Encoding errors from compile() were being masked.
623
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000624- When no module is given in a relative import, the module field of the
625 ImportFrom AST node is now None instead of an empty string.
626
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000627- Assignment to None using import statements now raises a SyntaxError.
628
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +0000629- Issue #4547: When debugging a very large function, it was not always
630 possible to update the lineno attribute of the current frame.
631
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000632- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000633 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000634
Raymond Hettinger578a2282009-05-29 04:58:52 +0000635- Issue #5982: staticmethod and classmethod now expose the wrapped
636 function with __func__.
637
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000638- Added support for multiple context managers in the same with-statement.
639 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +0000640
Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000641- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
642 statement and correctly lookup the __enter__ and __exit__ special methods.
643
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000644- Issue #5829: complex("1e500") no longer raises OverflowError. This
645 makes it consistent with float("1e500") and interpretation of real
646 and imaginary literals.
647
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000648- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
649
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000650- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
651 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000652
R. David Murray525cffc2009-05-13 13:07:14 +0000653- Issue #5994: the marshal module now has docstrings.
654
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000655- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
656 (1) inf and nan strings with trailing whitespace were incorrectly
657 rejected; (2) parsing of strings representing infinities and nans
658 was locale aware; and (3) the interpretation of fromhex('-nan')
659 didn't match that of float('-nan').
660
Eric Smitha985a3a2009-05-05 18:26:08 +0000661- Issue #5920: For float.__format__, change the behavior with the
662 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
663 to be like 'g' but with at least one decimal point and with a
664 default precision of 12. Previously, the behavior the same but with
665 a default precision of 6. This more closely matches str(), and
666 reduces surprises when adding alignment flags to the empty
667 presentation type. This also affects the new complex.__format__ in
668 the same way.
669
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000670- Issue #5890: in subclasses of 'property' the __doc__ attribute was
671 shadowed by classtype's, even if it was None. property now
672 inserts the __doc__ into the subclass instance __dict__.
673
Antoine Pitrou653dece2009-05-04 18:32:32 +0000674- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
675 sequences. Patch by Nick Barnes and Victor Stinner.
676
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000677- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000678 format(complex(1, 2./3), '.5') now produces a sensible result.
679

687 titlecase, but not their own uppercase.
688
Eric Smith068f0652009-04-25 21:40:15 +0000689- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
690 _PyOS_double_to_string or PyOS_double_to_string.
691
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000692- Issue #5283: Setting __class__ in __del__ caused a segfault.
693
Mark Dickinson95bc9802009-04-24 12:46:53 +0000694- Issue #5816: complex(repr(z)) now recovers z exactly, even when
695 z involves nans, infs or negative zeros.
696
Eric Smithaca19e62009-04-22 13:29:05 +0000697- Implement PEP 378, Format Specifier for Thousands Separator, for
698 floats, ints, and longs.
699
700- Issue #5515: 'n' formatting for ints, longs, and floats handles
701 leading zero formatting poorly.
702
703- Issue #5772: For float.__format__, don't add a trailing ".0" if
704 we're using no type code and we have an exponent.
705
Mark Dickinson6736cf82009-04-20 21:13:33 +0000706- Issue #3166: Make long -> float (and int -> float) conversions
707 correctly rounded.
708
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000709- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
710 some builtin types.
711
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000712- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000713 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000714
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000715- Issue #5759: float() didn't call __float__ on str subclasses.
716
Georg Brandl3c4a5462009-04-12 12:08:12 +0000717- Issue #5704: the "-3" command-line option now implies "-t".
718
R. David Murray0374a822009-04-09 21:54:50 +0000719- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
720 its clarity and its speed.
721
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000722- Issue #2396: the memoryview object was backported from Python 3.1.
723

728
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000729- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
730 the end sys.path, for compatibility with the system install of Python.
731
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000732- Issue #4688: Add a heuristic so that tuples and dicts containing only
733 untrackable objects are not tracked by the garbage collector. This can
734 reduce the size of collections and therefore the garbage collection overhead
735 on long-running programs, depending on their particular use of datatypes.
736
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000737- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
738 improve its performance. Long divisions and remainder operations
739 are now between 50% and 150% faster.
740
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000741- Issue #4258: Make it possible to use base 2**30 instead of base
742 2**15 for the internal representation of integers, for performance
743 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
744 --enable-big-digits option to configure, which overrides the
745 default. Add sys.long_info structseq to provide information about
746 the internal format.
747
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000748- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
749 result traceback.__members__ no longer exists.)
750
Mark Dickinson6b265f12009-03-18 16:07:26 +0000751- Issue #4474: PyUnicode_FromWideChar now converts characters outside
752 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
753 and sizeof(Py_UNICODE) == 2.
754
Eric Smith6f42edb2009-03-14 11:57:26 +0000755- Issue #5237: Allow auto-numbered fields in str.format(). For
756 example: '{} {}'.format(1, 2) == '1 2'.
757
Brett Cannon6c4cff02009-03-11 04:51:06 +0000758- Issue #3652: Make the 'line' argument for warnings.showwarning() a
759 requirement. Means the DeprecationWarning from Python 2.6 can go away.
760
Eric Smithe9fb6862009-02-20 14:02:36 +0000761- Issue #5247: Improve error message when unknown format codes are
762 used when using str.format() with str, unicode, long, int, and
763 float arguments.
764
Raymond Hettinger08259e82009-02-18 23:10:19 +0000765- Running Python with the -3 option now also warns about classic division
766 for ints and longs.
767
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000768- Issue #5260: Long integers now consume less memory: average
769 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
770 on a 64-bit system.
771
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000772- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
773 rotating the object pointer by 4 bits to the right.
774
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000775- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
776 it now forces its argument to double before testing for infinity.
777
Benjamin Petersone18ef192009-01-20 14:21:16 +0000778- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
779
Georg Brandl29c6a282009-04-05 20:23:13 +0000780- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000781 were suppressing all exceptions. These include list(), filter(), map(),
782 zip(), and bytearray().
783
Benjamin Peterson596d3062009-01-19 15:42:23 +0000784- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
785 functions.
786
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000787- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

791
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000792- Issue #4935: The overflow checking code in the expandtabs() method common
793 to str, bytes and bytearray could be optimized away by the compiler, letting
794 the interpreter segfault instead of raising an error.
795
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000796- Issue #3720: Fix a crash when an iterator modifies its class and removes its

802
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000803- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
804 collecting the oldest generation) so that allocating lots of objects without
805 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000806 Martin von Löwis at

810
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000811- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
812 an existing .py counterpart, override the co_filename attributes of all
813 code objects if the original filename is obsolete (which can happen if the
814 file has been renamed, moved, or if it is accessed through different paths).
815 Patch by Ziga Seilnacht and Jean-Paul Calderone.
816
Martin v. Löwis5344c992009-01-02 20:32:55 +0000817- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000819- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
820 file with `str' filename on Windows.
821
Antoine Pitrouaa687902009-01-01 14:11:22 +0000822- Issue #3680: Reference cycles created through a dict, set or deque iterator
823 did not get collected.
824
Nick Coghlan180e4002008-12-30 01:18:48 +0000825- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
826 where the tp_hash and tp_dict slots are both NULL.
827
Benjamin Peterson7af65562008-12-29 17:56:58 +0000828- Issue #4764: With io.open, IOError.filename is set when trying to open a
829 directory on POSIX systems.
830
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000831- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

835 bytearray.translate(). It was always allowed for bytes.translate().
836
Skip Montanarof205c132008-12-23 03:30:15 +0000837- Added test case to ensure attempts to read from a file opened for writing
838 fail.
839
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000840- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
841 print elapsed times, not only when some objects are uncollectable /
842 unreachable. Original patch by Neil Schemenauer.
843
Mark Dickinson1a707982008-12-17 16:14:37 +0000844- Issue #3439: Add a bit_length method to int and long.

Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000849- Issue #4597: Fixed exception handling when the __exit__ function of a
850 context manager returns a value that cannot be converted to a bool.
851
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000852- Issue #4597: Fixed several opcodes that weren't always propagating
853 exceptions.
854
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000855- Issue #4445: Replace "sizeof(PyStringObject)" with
856 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
857 str instances. On a typical machine this saves 3 bytes of memory
858 (on average) per string allocation.
859
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000860- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
861 interpreter to abort ("Fatal Python error: Could not reset the stack!")
862 instead of throwing a MemoryError.
863
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000864- Issue #3689: The list reversed iterator now supports __length_hint__
865 instead of __len__. Behavior now matches other reversed iterators.
866
Benjamin Petersonc078f922008-11-21 22:27:24 +0000867- Issue #4367: Python would segfault during compiling when the unicodedata
868 module couldn't be imported and \N escapes were present.
869
Vinay Sajip213faca2008-12-03 23:22:58 +0000870- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000871 method on file objects with closefd=False. The file descriptor is still
872 kept open but the file object behaves like a closed file. The ``FileIO``
873 object also got a new readonly attribute ``closefd``.
874
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000875- Issue #4348: Some bytearray methods returned that didn't cause any change to
876 the bytearray, returned the same bytearray instead of a copy.
877
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000878- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
879
Benjamin Peterson273c2332008-11-17 22:39:09 +0000880- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
881
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000882- Issue #4048: The parser module now correctly validates relative imports.
883
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000884- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
885 exec statement.
886
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000887- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
888 method does not return iterators for the 4th and 5th items.
889
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000890- Issue #4209: Enabling unicode_literals and the print_function in the same
891 __future__ import didn't work.
892
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000893- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000894 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000895
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000896- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
897 returned a path longer than MAX_PATH. (But It's doubtful this code path is
898 really executed because I cannot move to such directory on win2k)
899
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000900- Issue #4069: When set.remove(element) is used with a set element, the element
901 is temporarily replaced with an equivalent frozenset. But the eventual
902 KeyError would always report the empty frozenset([]) as the missing key. Now

2171 leak-chasing test runs give sensible results. The previous method of

2313
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002314- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2315
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002316- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2317 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2318 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2319 ``printf`` function, whereas PyString_FromFormat has an independent
2320 implementation and uses "%zd" on all platforms for size_t values.
2321 This makes a difference on win64, where ``printf`` needs "%Id" to display
2322 64bit values.
2323
Benjamin Peterson97179b02008-09-09 20:55:01 +00002324- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2325 error.
2326
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002327- Issue #3777: long() applied to a float object now always return a long
2328 object; previously an int would be returned for small values. the __long__
2329 method is allowed to return either an int or a long, but the behaviour of
2330 float objects should not change to respect backward compatibility.
2331
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002332- Issue #3751: str.rpartition would perform a left-partition when called with
2333 a unicode argument.
2334
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002335- Issue #3683: Fix compilation when --without-threads is given.
2336
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002337- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002338 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002339 was correctly parsed but parsing of subsequent arguments failed.
2340
Vinay Sajip35e3b032008-09-01 14:33:59 +00002341- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002342 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2343 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2344 when given a tuple of classes as second argument, were looking up
2345 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2346 type object.
2347
Neal Norwitz18aa3882008-08-24 05:04:52 +00002348- Fix crashes on memory allocation failure found with failmalloc.
2349
2350- Fix memory leaks found with valgrind and update suppressions file.
2351
2352- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Christian Heimes7d4c3172008-08-22 19:47:25 +00002356- Silenced another compiler warning about a used but not defined
2357 function 'stringlib_contains_obj'.

Nick Coghland2e09382008-09-11 12:11:06 +00002390- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002391 return a list or None rather than a custom object.

2417 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2418 for catch_warnings() also led to an improvement in the raising of a
2419 DeprecationWarning related to warnings.warn_explicit().
2420
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002421- The deprecation warnings for the old camelCase threading API were removed.

2491-----------------
2492
Guido van Rossumf8402962008-08-20 15:01:50 +00002493- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2494 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2495 extensions do not automatically benefit from the class attribute
2496 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2497 to their tp_flags field if they care. This is a backwards
2498 compatibility feature; in 3.0, all types will use the cache by
2499 default.
2500
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002501- Keyword arguments can now follow starred arguments. (``f(a, *args,
2502 keyword=23)`` is now valid syntax.)
2503
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002504- ctypes function pointers that are COM methods have a boolean True
2505 value again.
2506
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002507- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2508 by denying s# to parse objects that have a releasebuffer procedure,
2509 and introducing s*.
2510
Georg Brandl1e13ea92008-08-11 09:07:59 +00002511- Issue #3537: Fix an assertion failure when an empty but presized dict
2512 object was stored in the freelist.
2513
Mark Dickinsonb6467572008-08-04 21:30:09 +00002514- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2515 ValueError consistently across platforms.
2516
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002517- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2518 (64bit Unix, for example), unichr() would truncate its argument and return
2519 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2520
Neal Norwitze7d8be82008-07-31 17:17:14 +00002521- Apply security patches from Apple.
2522
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002523- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2524 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2525
Antoine Pitrou92f82162008-07-25 22:22:08 +00002526- Issue #1819: function calls with several named parameters are now on
2527 average 35% faster (as measured by pybench).
2528
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002529- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2530 the python debugger steps into a class statement: the free variables (local
2531 variables defined in an outer scope) would be deleted from the outer scope.
2532
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002533- Issue #2620: Overflow checking when allocating or reallocating memory
2534 was not always being done properly in some python types and extension
2535 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2536 all been updated to perform better checks and places in the code that
2537 would previously leak memory on the error path when such an allocation
2538 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002543- Issue #3612: Added some missing basic types in ctypes.wintypes.
2544
Benjamin Petersone977ad42008-08-20 01:42:01 +00002545- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2546 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2547
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002548- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2549 version reported by these tools does not necessarily follow the python
2550 version numbering scheme, so the module is less strict when parsing it.
2551
Nick Coghlanf70385a2008-08-18 12:42:46 +00002552- Issue #2235: Added Py3k warnings for types which will become unhashable
2553 under the stricter __hash__ inheritance rules in 3.0. Several types
2554 which did not meet the rules for hash invariants and were already
2555 unhashable in 3.0 have now been explicitly flagged as unhashable in
2556 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2557 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2558
Brett Cannon88f801d2008-08-18 00:46:22 +00002559- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2560 imported into the module but exposed as part of the module's API.
2561

2672
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002673- Issue #643841: The language reference now provides more detailed

2685-----------------
2686
Georg Brandl3e483f62008-07-16 22:57:41 +00002687- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2688 its methods now allow for items objects that can be converted to
2689 an integer using operator.index().
2690
Mark Dickinson64b7e502008-07-16 09:40:03 +00002691- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2692 produced a ValueError instead of giving the correct float.
2693
Eric Smitha5fa5a22008-07-16 00:11:49 +00002694- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2695 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2696
Mark Dickinson7103aa42008-07-15 19:08:33 +00002697- Issue #3008: the float type has a new instance method 'float.hex'
2698 and a new class method 'float.fromhex' to convert floating-point
2699 numbers to and from hexadecimal strings, respectively.
2700
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002701- Issue #2235: __hash__ is once again inherited by default. To allow
2702 collections.Hashable to remain meaningful in the presence of the
2703 default hash implementation (object.__hash__), it is now possible
2704 to explicit block inheritance of hash by setting __hash__=None at
2705 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2706 level.
2707
Nick Coghlanb028f502008-07-13 14:52:36 +00002708- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2709 the parent module cannot be found while performing an absolute import.
2710 This means that an incorrectly defined __package__ attribute will
2711 now only prevent relative imports in that module rather than causing
2712 all imports from that module to fail.
2713
Nick Coghlan14ff9942008-07-08 14:21:42 +00002714- Issue #2517: Allow unicode messages in Exceptions again by correctly

2724 another thread's dictionary.
2725
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002726- Issue #3004: Minor change to slice.indices(): the start and stop
2727 arguments are now treated identically, making the behaviour easier
2728 to describe and understand. For example, slice(None, -10,
2729 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2730 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2731 10, -1).
2732
Georg Brandl278fc502008-07-19 12:46:12 +00002733- Issue #3219: Calling a function with repeated keyword arguments,
2734 f(a=2, a=23), would not cause a syntax error. This was a regression
2735 from 2.4 caused by the switch to the new compiler.

2774 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002775 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002776 content-length. The problem had been corrected in the 2.4 branch, but never

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003183- On MacOS X it is now possible to install the framework in 64-bit
3184 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003185 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003186
3187 This is controlled by the configure argument ``--with-universal-archs``:
3188
3189 - ``--with-universal-archs=all``: install 4-way universal
3190
3191 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3192
3193 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3194
3195 This option should be used in combination with ``--enable-universalsdk=``.
3196
3197 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 +00003247- Issue #1631171: Re-implement the 'warnings' module in C (the
3248 original Python code has been kept as backup). This will allow for
3249 using the 'warning's machinery in such places as the parser where
3250 use of pure Python code is not possible. Both the ``showarning()``
3251 and ``formatwarning()`` gain an optional 'line' argument which is
3252 not called by default for backwards-compatibility reasons. Setting
3253 ``warnings.showwarning()`` to an implementation that lacks support
3254 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003317- Issue #2550: The approach used by client/server code for obtaining
3318 ports to listen on in network-oriented tests has been refined in an
3319 effort to facilitate running multiple instances of the entire
3320 regression test suite in parallel without issue.
3321 test_support.bind_port() has been fixed such that it will always
3322 return a unique port -- which wasn't always the case with the
3323 previous implementation, especially if socket options had been set
3324 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3325 new implementation of bind_port() will actually raise an exception
3326 if it is passed an AF_INET/SOCK_STREAM socket with either the
3327 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3328 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3329 the socket it's been passed. This currently only applies to
3330 Windows. This option prevents any other sockets from binding to the
3331 host/port we've bound to, thus removing the possibility of the
3332 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3333 when a second SOCK_STREAM socket binds and accepts to a host/port
3334 that's already been bound by another socket. The optional preferred
3335 port parameter to bind_port() has been removed. Under no
3336 circumstances should tests be hard coding ports!
3337
3338 test_support.find_unused_port() has also been introduced, which will
3339 pass a temporary socket object to bind_port() in order to obtain an
3340 unused port. The temporary socket object is then closed and
3341 deleted, and the port is returned. This method should only be used
3342 for obtaining an unused port in order to pass to an external program
3343 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3344 a parameter to a server-oriented class that doesn't give you direct
3345 access to the underlying socket used.
3346
3347 Finally, test_support.HOST has been introduced, which should be used
3348 for the host argument of any relevant socket calls (i.e. bind and
3349 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003350
3351 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003352 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003353 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3354 test_asynchat and test_socket_ssl.
3355
Georg Brandl3ee81df2008-05-17 18:14:43 +00003356 It is now possible for multiple instances of the regression test
3357 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003411- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003412 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3413 Plane. This affected raw unicode literals and the
3414 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3415 this case, like normal unicode literals and the 'unicode-escape'
3416 codec.

3624-----------------
3625
Fred Drakea8ee94b2008-03-01 02:45:07 +00003626- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003627 644. The mode is now inherited from the py file.

3630
3631- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003632
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003633- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003634 issue 215555 for a discussion.
3635
Eric Smitha73fbe72008-02-23 03:09:44 +00003636- Added the future_builtins module, which contains hex() and oct().
3637 These are the PEP 3127 version of these functions, designed to be
3638 compatible with the hex() and oct() builtins from Python 3.0. They
3639 differ slightly in their output formats from the existing, unchanged
3640 Python 2.6 builtins. The expected usage of the future_builtins
3641 module is:
3642 from future_builtins import hex, oct
3643
Eric Smith7ef40bf2008-02-20 23:34:22 +00003644- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3645 exponents for exponents with absolute value < 100. Follows C99
3646 standard. This is a change on Windows, which would use 3 digits.
3647 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3648 so that any alterations it does to the resulting string will be
3649 available in stringlib/formatter.h (for float.__format__).
3650
Eric Smith5a3c1352008-02-19 13:21:56 +00003651- Implemented PEP 3101, Advanced String Formatting. This adds a new
3652 builtin format(); a format() method for str and unicode; a
3653 __format__() method to object, str, unicode, int, long, float, and
3654 datetime; the class string.Formatter; and the C API
3655 PyObject_Format().
3656
Georg Brandl3ee81df2008-05-17 18:14:43 +00003657- Fixed several potential crashes, all caused by specially crafted
3658 __del__ methods exploiting objects in temporarily inconsistent
3659 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003660
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003661- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003662 prevent a possible crash: an Abstract Base Class would try to access
3663 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003664

Georg Brandl3ee81df2008-05-17 18:14:43 +00003668- Clear all free lists during a gc.collect() of the highest generation
3669 in order to allow pymalloc to free more arenas. Python may give back
3670 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003671
Georg Brandl3ee81df2008-05-17 18:14:43 +00003672- Issue #2045: Fix an infinite recursion triggered when printing a
3673 subclass of collections.defaultdict, if its default_factory is set

Georg Brandl3ee81df2008-05-17 18:14:43 +00003682- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3683 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003684 to compact the internal free lists of pre-allocted ints and floats.
3685
Georg Brandl3ee81df2008-05-17 18:14:43 +00003686- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3687 calls. Python expected the return type int but the fork familie
3688 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003689
Georg Brandl3ee81df2008-05-17 18:14:43 +00003690- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3691 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003702- Patch #1473257: generator objects gain a gi_code attribute. This is
3703 the same object as the func_code attribute of the function that
3704 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003705
Georg Brandl3ee81df2008-05-17 18:14:43 +00003706- Issue #1920: "while 0" statements were completely removed by the
3707 compiler, even in the presence of an "else" clause, which is
3708 supposed to be run when the condition is false. Now the compiler
3709 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003710
Guido van Rossumeead05f2008-01-24 18:21:02 +00003711- A few crashers fixed: weakref_in_del.py (issue #1377858);
3712 loosing_dict_ref.py (issue #1303614, test67.py);
3713 borrowed_ref_[34].py (not in tracker).
3714
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003715- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003716 suppressed while an extension is loaded by calling SetErrorMode in
3717 dynload_win.c. The error is still reported properly.
3718
Georg Brandl3ee81df2008-05-17 18:14:43 +00003719- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003720 several extension methods and modules do not work without unicode
3721 support.
3722
Georg Brandl26543b12008-01-21 18:36:51 +00003723- Issue #1882: when compiling code from a string, encoding cookies in the

3725
Georg Brandl14404b62008-01-19 19:27:05 +00003726- Issue #1679: "0x" was taken as a valid integer literal.
3727
Georg Brandl6caad7d2008-01-26 14:19:22 +00003728- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003729 added.
3730
Christian Heimesc94e2b52008-01-14 04:13:37 +00003731- sys.float_info / PyFloat_GetInfo: The floating point information
3732 object was converted from a dict to a specialized structseq object.
3733
Georg Brandl3ee81df2008-05-17 18:14:43 +00003734- Patch #1816: Added sys.flags structseq. It exposes the status of
3735 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003736
Georg Brandl3ee81df2008-05-17 18:14:43 +00003737- Objects/structseq.c: Implemented new structseq representation. The
3738 patch makes structseqs (e.g. the return value of os.stat) more
3739 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003740
Georg Brandl3ee81df2008-05-17 18:14:43 +00003741- Patch #1700288: added a type attribute cache that caches method
3742 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003743
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003744- Bug #1776: __import__() no longer accepts filenames on any platform.
3745 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003746
Georg Brandlaed6c662008-01-07 17:25:53 +00003747- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3748

3750 envvar and sys.dont_write_bytecode attribute. All these can be set
3751 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003752
Georg Brandl3ee81df2008-05-17 18:14:43 +00003753- Improve some exception messages when Windows fails to load an
3754 extension module. Now we get for example '%1 is not a valid Win32
3755 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003756

Christian Heimes0a8143f2007-12-18 23:22:54 +00003762- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003763 and INF. float("nan"), float("inf") and float("-inf") now work on
3764 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Compiler now generates simpler and faster code for dictionary
3767 literals. The oparg for BUILD_MAP now indicates an estimated
3768 dictionary size. There is a new opcode, STORE_MAP, for adding
3769 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003798- Patch #1739468: Directories and zipfiles containing a __main__.py
3799 file can now be directly executed by passing their name to the
3800 interpreter. The directory/zipfile is automatically inserted as the
3801 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003802
Georg Brandl3ee81df2008-05-17 18:14:43 +00003803- Issue #1265: Fix a problem with sys.settrace, if the tracing
3804 function uses a generator expression when at the same time the
3805 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003806
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003807- sets and frozensets now have an isdisjoint() method.
3808

3812
Georg Brandl3ee81df2008-05-17 18:14:43 +00003813- The enumerate() builtin function is no longer bounded to sequences
3814 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3815 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003816
Georg Brandl3ee81df2008-05-17 18:14:43 +00003817- Issue #1686386: Tuple's tp_repr did not take into account the
3818 possibility of having a self-referential tuple, which is possible
3819 from C code. Nor did object's tp_str consider that a type's tp_str
3820 could do something that could lead to an inifinite recursion.
3821 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3822 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003823
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824- Issue #1164: It was possible to trigger deadlock when using the
3825 'print' statement to write to a file since the GIL was not released
3826 as needed. Now PyObject_Print() does the right thing along with
3827 various tp_print implementations of the built-in types and those in
3828 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003829
Georg Brandl3ee81df2008-05-17 18:14:43 +00003830- Issue #1147: Exceptions were directly allowing string exceptions in

3832 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003833

Brett Cannon1e534b52007-09-07 04:18:30 +00003837- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003838 PyObject_Call() never calling back out to Python code to trigger
3839 recursion depth updates/checks. Required the creation of a static
3840 RuntimeError instance in case normalizing an exception put the
3841 recursion check value past its limit. Fixes crashers
3842 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003843

Neal Norwitz0ac60192007-05-27 04:08:54 +00003857- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858 __*__ attributes. (Some already existed, e.g., __doc__ and
3859 __name__.)

3865 calls.
3866
Collin Winter62903052007-05-18 23:11:24 +00003867- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003868 "except E as target:". This is to provide forwards compatibility
3869 with Python 3.0.

3875
Vinay Sajip8549ce32007-05-06 17:53:37 +00003876- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003877 setting a plain string, ie don't expand to single letter identifiers.
3878
Raymond Hettinger13936692007-04-11 18:40:58 +00003879- Request #1191699: Slices can now be pickled.
3880
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003881- Request #1193128: str.translate() now allows a None argument for

3883 remaining characters.
3884
Georg Brandl5cb76c12007-03-21 09:00:39 +00003885- Patch #1682205: a TypeError while unpacking an iterable is no longer
3886 masked by a generic one with the message "unpack non-sequence".
3887
Neal Norwitzaa754b72007-03-21 06:39:48 +00003888- Remove unused file Python/fmod.c.
3889
Guido van Rossum143b5642007-03-23 04:58:42 +00003890- Bug #1683368: The object.__init__() and object.__new__() methods are
3891 now stricter in rejecting excess arguments. The only time when
3892 either allows excess arguments is when it is not overridden and the
3893 other one is. For backwards compatibility, when both are
3894 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003895 warning later). Also, type.__init__() insists on the same signature
3896 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003898- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3899 object to complex using its __complex__() method before falling back
3900 to the __float__() method. Therefore, the functions in the cmath
3901 module now can operate on objects that define a __complex__()
3902 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003924 its argument, if it exists. If not, it will work like before. This
3925 allows customizing the output of dir() in the presence of a
3926 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003938- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003939 makes the filenames the warning module prints much more sensible
3940 when a PYTHONSTARTUP file is used.

Georg Brandl2c1375c2006-10-12 11:27:59 +00004008- Bug #1545497: when given an explicit base, int() did ignore NULs
4009 embedded in the string to convert.
4010
Georg Brandl846f73a2006-10-08 07:11:54 +00004011- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004059 generator expressions (x for x, in ... ) works again. Fixing this
4060 problem required changing the .pyc magic number. This means that
4061 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004868- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4869 with RFC 3207 and forgets any knowledge obtained from the server not
4870 obtained from the TLS negotiation itself. Patch contributed by Bill
4871 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004872
Georg Brandl3ee81df2008-05-17 18:14:43 +00004873- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004874 that the SMTP.starttls() caller no longer needs to call ehlo()
4875 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004876 does not claim to support starttls. Adds the
4877 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4958 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4959 silently miscode subclasses of those types. Now, it raises a
4960 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004961

Georg Brandl3ee81df2008-05-17 18:14:43 +00004976 time so that opening a database previously created with the DB_DUP
4977 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4978 opens. Specifically: dictionary assignment to a DB object will
4979 replace all values for a given key when the database allows
4980 duplicate values. DB users should use DB.put(k, v) when they want
4981 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004982

4988 characters with ASCII value less than 32. Also, it correctly quotes
4989 dots only if they occur on a single line, as opposed to the previous
4990 behavior of quoting dots if they are the second character of any
4991 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004992
