171 allowed by the XML specification, and are necessary when outputting e.g.
172 PHP code in a processing instruction. Patch by Neil Muller.

210 encoded string for them. This ensure that the upload and register commands
211 send the right values to PyPI without any error.
212
R. David Murrayed44dfa2010-01-16 05:15:17 +0000213- Issue #1670765: Prevent email.generator.Generator from re-wrapping

Eric Smithc4ab8332009-11-29 17:40:57 +0000470- Issue #3382: 'F' formatting for float and complex now convert the
471 result to upper case. This only affects 'inf' and 'nan', since 'f'
472 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000473

487
Mark Dickinsonb678de82009-11-19 18:41:49 +0000488- Issue #7117: repr(x) for a float x returns a result based on the
489 shortest decimal string that's guaranteed to round back to x under
490 correct rounding (with round-half-to-even rounding mode).
491 Previously it gave a string based on rounding x to 17 decimal digits.
492 repr(x) for a complex number behaves similarly. On platforms where
493 the correctly-rounded strtod and dtoa code is not supported (see below),
494 repr is unchanged.
495
496- Issue #7117: On almost all platforms: float-to-string and
497 string-to-float conversions within Python are now correctly rounded.
498 Places these conversions occur include: str for floats and complex
499 numbers; the float and complex constructors; old-style and new-style
500 numeric formatting; serialization and deserialization of floats and
501 complex numbers using marshal, pickle and json; parsing of float and
502 imaginary literals in Python code; Decimal-to-float conversion.
503
504 The conversions use a Python-adapted version of David Gay's
505 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
506 functions. This code is supported on Windows, and on Unix-like
507 platforms using gcc, icc or suncc as the C compiler. There may be a
508 small number of platforms on which correct operation of this code
509 cannot be guaranteed, so the code is not used: notably, this applies
510 to platforms where the C double format is not IEEE 754 binary64, and
511 to platforms on x86 hardware where the x87 FPU is set to 64-bit
512 precision and Python's configure script is unable to determine how
513 to change the FPU precision. On these platforms conversions use the
514 platform strtod and dtoa, as before.
515
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000516- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000517 now uses the correctly-rounded string <-> float conversions
518 described above (when available), and so produces correctly rounded
519 results that will display nicely under the float repr. There are
520 two related small changes: (1) round now accepts any class with an
521 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000522 floats for the second argument), and (2) an excessively large second
523 integer argument (e.g., round(1.234, 10**100)) no longer raises an
524 exception.

Benjamin Peterson753d1622009-07-02 18:16:45 +0000613- Issue #4618: When unicode arguments are passed to print(), the default
614 separator and end should be unicode also.
615
Benjamin Peterson1bf47652009-07-02 17:06:17 +0000616- Issue #6119: Fixed a incorrect Py3k warning about order comparisons of builtin
617 functions and methods.
618
Mark Dickinson2f865b92009-06-30 15:32:30 +0000619- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
620 This fixes a build failure on HP-UX: int32_t and uint32_t are
621 defined in inttypes.h instead of stdint.h on that platform.
622

Raymond Hettinger62641e92009-06-23 20:59:43 +0000630- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
631 because it wasn't recognized as a sequence).
632
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +0000633- Issue #6289: Encoding errors from compile() were being masked.
634
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000635- When no module is given in a relative import, the module field of the
636 ImportFrom AST node is now None instead of an empty string.
637
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000638- Assignment to None using import statements now raises a SyntaxError.
639
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +0000640- Issue #4547: When debugging a very large function, it was not always
641 possible to update the lineno attribute of the current frame.
642
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000643- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000644 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000645
Raymond Hettinger578a2282009-05-29 04:58:52 +0000646- Issue #5982: staticmethod and classmethod now expose the wrapped
647 function with __func__.
648
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000649- Added support for multiple context managers in the same with-statement.
650 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +0000651
Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000652- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
653 statement and correctly lookup the __enter__ and __exit__ special methods.
654
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000655- Issue #5829: complex("1e500") no longer raises OverflowError. This
656 makes it consistent with float("1e500") and interpretation of real
657 and imaginary literals.
658
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000659- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
660

662 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000663
R. David Murray525cffc2009-05-13 13:07:14 +0000664- Issue #5994: the marshal module now has docstrings.
665
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000666- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
667 (1) inf and nan strings with trailing whitespace were incorrectly
668 rejected; (2) parsing of strings representing infinities and nans
669 was locale aware; and (3) the interpretation of fromhex('-nan')
670 didn't match that of float('-nan').
671
Eric Smitha985a3a2009-05-05 18:26:08 +0000672- Issue #5920: For float.__format__, change the behavior with the
673 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
674 to be like 'g' but with at least one decimal point and with a
675 default precision of 12. Previously, the behavior the same but with
676 a default precision of 6. This more closely matches str(), and
677 reduces surprises when adding alignment flags to the empty
678 presentation type. This also affects the new complex.__format__ in
679 the same way.
680
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000681- Issue #5890: in subclasses of 'property' the __doc__ attribute was
682 shadowed by classtype's, even if it was None. property now
683 inserts the __doc__ into the subclass instance __dict__.
684
Antoine Pitrou653dece2009-05-04 18:32:32 +0000685- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
686 sequences. Patch by Nick Barnes and Victor Stinner.
687
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000688- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000689 format(complex(1, 2./3), '.5') now produces a sensible result.
690
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000691- Issue #5864: Fix empty format code formatting for floats so that it
692 never gives more than the requested number of significant digits.
693
Eric Smithcac7af62009-04-27 19:04:37 +0000694- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

698 titlecase, but not their own uppercase.
699
Eric Smith068f0652009-04-25 21:40:15 +0000700- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
701 _PyOS_double_to_string or PyOS_double_to_string.
702
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000703- Issue #5283: Setting __class__ in __del__ caused a segfault.
704
Mark Dickinson95bc9802009-04-24 12:46:53 +0000705- Issue #5816: complex(repr(z)) now recovers z exactly, even when
706 z involves nans, infs or negative zeros.
707
Eric Smithaca19e62009-04-22 13:29:05 +0000708- Implement PEP 378, Format Specifier for Thousands Separator, for
709 floats, ints, and longs.
710
711- Issue #5515: 'n' formatting for ints, longs, and floats handles
712 leading zero formatting poorly.
713
714- Issue #5772: For float.__format__, don't add a trailing ".0" if
715 we're using no type code and we have an exponent.
716
Mark Dickinson6736cf82009-04-20 21:13:33 +0000717- Issue #3166: Make long -> float (and int -> float) conversions
718 correctly rounded.
719
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000720- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
721 some builtin types.
722
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000723- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000724 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000725
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000726- Issue #5759: float() didn't call __float__ on str subclasses.
727
Georg Brandl3c4a5462009-04-12 12:08:12 +0000728- Issue #5704: the "-3" command-line option now implies "-t".
729
R. David Murray0374a822009-04-09 21:54:50 +0000730- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
731 its clarity and its speed.
732
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000733- Issue #2396: the memoryview object was backported from Python 3.1.
734

Ronald Oussorene0154ed2009-03-30 23:10:35 +0000740- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
741 the end sys.path, for compatibility with the system install of Python.
742
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000743- Issue #4688: Add a heuristic so that tuples and dicts containing only
744 untrackable objects are not tracked by the garbage collector. This can
745 reduce the size of collections and therefore the garbage collection overhead
746 on long-running programs, depending on their particular use of datatypes.
747
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000748- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
749 improve its performance. Long divisions and remainder operations
750 are now between 50% and 150% faster.
751
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000752- Issue #4258: Make it possible to use base 2**30 instead of base
753 2**15 for the internal representation of integers, for performance
754 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
755 --enable-big-digits option to configure, which overrides the
756 default. Add sys.long_info structseq to provide information about
757 the internal format.
758
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000759- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
760 result traceback.__members__ no longer exists.)
761
Mark Dickinson6b265f12009-03-18 16:07:26 +0000762- Issue #4474: PyUnicode_FromWideChar now converts characters outside
763 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
764 and sizeof(Py_UNICODE) == 2.
765
Eric Smith6f42edb2009-03-14 11:57:26 +0000766- Issue #5237: Allow auto-numbered fields in str.format(). For
767 example: '{} {}'.format(1, 2) == '1 2'.
768
Brett Cannon6c4cff02009-03-11 04:51:06 +0000769- Issue #3652: Make the 'line' argument for warnings.showwarning() a
770 requirement. Means the DeprecationWarning from Python 2.6 can go away.
771
Eric Smithe9fb6862009-02-20 14:02:36 +0000772- Issue #5247: Improve error message when unknown format codes are
773 used when using str.format() with str, unicode, long, int, and
774 float arguments.
775
Raymond Hettinger08259e82009-02-18 23:10:19 +0000776- Running Python with the -3 option now also warns about classic division
777 for ints and longs.
778
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000779- Issue #5260: Long integers now consume less memory: average
780 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
781 on a 64-bit system.
782
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000783- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
784 rotating the object pointer by 4 bits to the right.
785
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000786- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
787 it now forces its argument to double before testing for infinity.
788
Benjamin Petersone18ef192009-01-20 14:21:16 +0000789- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
790
Georg Brandl29c6a282009-04-05 20:23:13 +0000791- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000792 were suppressing all exceptions. These include list(), filter(), map(),
793 zip(), and bytearray().
794
Benjamin Peterson596d3062009-01-19 15:42:23 +0000795- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
796 functions.
797
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000798- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
799 OSError.

802
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000803- Issue #4935: The overflow checking code in the expandtabs() method common
804 to str, bytes and bytearray could be optimized away by the compiler, letting
805 the interpreter segfault instead of raising an error.
806
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000807- Issue #3720: Fix a crash when an iterator modifies its class and removes its

813
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000814- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
815 collecting the oldest generation) so that allocating lots of objects without
816 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000817 Martin von Löwis at

821
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000822- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
823 an existing .py counterpart, override the co_filename attributes of all
824 code objects if the original filename is obsolete (which can happen if the
825 file has been renamed, moved, or if it is accessed through different paths).
826 Patch by Ziga Seilnacht and Jean-Paul Calderone.
827
Martin v. Löwis5344c992009-01-02 20:32:55 +0000828- Issue #4075: Use OutputDebugStringW in Py_FatalError.

837 where the tp_hash and tp_dict slots are both NULL.
838
Benjamin Peterson7af65562008-12-29 17:56:58 +0000839- Issue #4764: With io.open, IOError.filename is set when trying to open a

849 fail.
850
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000851- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
852 print elapsed times, not only when some objects are uncollectable /
853 unreachable. Original patch by Neil Schemenauer.
854

865
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000866- Issue #4445: Replace "sizeof(PyStringObject)" with
867 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
868 str instances. On a typical machine this saves 3 bytes of memory
869 (on average) per string allocation.
870
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000871- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000882 method on file objects with closefd=False. The file descriptor is still
883 kept open but the file object behaves like a closed file. The ``FileIO``
884 object also got a new readonly attribute ``closefd``.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000907- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
908 returned a path longer than MAX_PATH. (But It's doubtful this code path is
909 really executed because I cannot move to such directory on win2k)

Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000911- Issue #4069: When set.remove(element) is used with a set element, the element
912 is temporarily replaced with an equivalent frozenset. But the eventual

914 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000934- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
935 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
936 step. This avoids problems with counting UTF-8 bytes that ignores the effect
937 of using the replace error handler in PyUnicode_DecodeUTF8().
938
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000939- Issue #3739: The unicode-internal encoder now reports the number of characters

941
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000942- Issue #2422: When compiled with the ``--with-valgrind`` option, the
943 pymalloc allocator will be automatically disabled when running under
944 Valgrind. This gives improved memory leak detection when running
945 under Valgrind, while taking advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002325- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2326
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002327- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2328 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2329 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2330 ``printf`` function, whereas PyString_FromFormat has an independent
2331 implementation and uses "%zd" on all platforms for size_t values.
2332 This makes a difference on win64, where ``printf`` needs "%Id" to display
2333 64bit values.
2334
Benjamin Peterson97179b02008-09-09 20:55:01 +00002335- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2336 error.
2337
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002338- Issue #3777: long() applied to a float object now always return a long
2339 object; previously an int would be returned for small values. the __long__
2340 method is allowed to return either an int or a long, but the behaviour of
2341 float objects should not change to respect backward compatibility.
2342
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002343- Issue #3751: str.rpartition would perform a left-partition when called with
2344 a unicode argument.
2345
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002346- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002349 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002350 was correctly parsed but parsing of subsequent arguments failed.
2351
Vinay Sajip35e3b032008-09-01 14:33:59 +00002352- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002353 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2354 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2355 when given a tuple of classes as second argument, were looking up
2356 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2357 type object.
2358
Neal Norwitz18aa3882008-08-24 05:04:52 +00002359- Fix crashes on memory allocation failure found with failmalloc.

2428 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2429 for catch_warnings() also led to an improvement in the raising of a
2430 DeprecationWarning related to warnings.warn_explicit().

2502-----------------
2503
Guido van Rossumf8402962008-08-20 15:01:50 +00002504- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2505 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2506 extensions do not automatically benefit from the class attribute
2507 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2508 to their tp_flags field if they care. This is a backwards
2509 compatibility feature; in 3.0, all types will use the cache by
2510 default.
2511
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002512- Keyword arguments can now follow starred arguments. (``f(a, *args,
2513 keyword=23)`` is now valid syntax.)
2514
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002515- ctypes function pointers that are COM methods have a boolean True
2516 value again.
2517
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002518- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2519 by denying s# to parse objects that have a releasebuffer procedure,
2520 and introducing s*.
2521
Georg Brandl1e13ea92008-08-11 09:07:59 +00002522- Issue #3537: Fix an assertion failure when an empty but presized dict
2523 object was stored in the freelist.
2524
Mark Dickinsonb6467572008-08-04 21:30:09 +00002525- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2526 ValueError consistently across platforms.
2527
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002528- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2529 (64bit Unix, for example), unichr() would truncate its argument and return
2530 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2531
Neal Norwitze7d8be82008-07-31 17:17:14 +00002532- Apply security patches from Apple.
2533
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002534- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2535 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2536
Antoine Pitrou92f82162008-07-25 22:22:08 +00002537- Issue #1819: function calls with several named parameters are now on
2538 average 35% faster (as measured by pybench).
2539
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002540- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2541 the python debugger steps into a class statement: the free variables (local
2542 variables defined in an outer scope) would be deleted from the outer scope.
2543
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002544- Issue #2620: Overflow checking when allocating or reallocating memory
2545 was not always being done properly in some python types and extension
2546 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2547 all been updated to perform better checks and places in the code that
2548 would previously leak memory on the error path when such an allocation
2549 failed have been fixed.

2555
Benjamin Petersone977ad42008-08-20 01:42:01 +00002556- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2557 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2558
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002559- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2560 version reported by these tools does not necessarily follow the python
2561 version numbering scheme, so the module is less strict when parsing it.
2562
Nick Coghlanf70385a2008-08-18 12:42:46 +00002563- Issue #2235: Added Py3k warnings for types which will become unhashable
2564 under the stricter __hash__ inheritance rules in 3.0. Several types
2565 which did not meet the rules for hash invariants and were already
2566 unhashable in 3.0 have now been explicitly flagged as unhashable in
2567 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2568 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2569
Brett Cannon88f801d2008-08-18 00:46:22 +00002570- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2599 thread-safe.
2600
Brett Cannonbf3157b2008-08-14 05:00:03 +00002601- Silence the DeprecationWarning of rfc822 when it is imported by mimetools

2603 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2604

2617 to _sre.compile() will now be rejected. This should not affect anybody
2618 since the re.compile() function never generates invalid re-bytecode.

2622 it wasn't initialized during instantiation.
2623
Brett Cannon3aa2a492008-08-06 22:28:09 +00002624- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2625 the reload() built-in has been removed.

2636 raised an AttributeError.
2637
Benjamin Peterson01a24322008-07-28 23:35:27 +00002638- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002639 asking for a specific length. This problem only affected files opened
2640 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002641

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002665- Issue #3394: zipfile.writestr sets external attributes when passed a
2666 file name rather than a ZipInfo instance, so files are extracted with
2667 mode 0600 rather than 000 under Unix.
2668
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002669- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002681- Issue #2235: the C API function PyObject_HashNotImplemented and its
2682 interaction with the tp_hash slot (added in 2.6b2) are now documented
2683
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002684- Issue #643841: The language reference now provides more detailed
2685 coverage of the lookup process for special methods. The disclaimers
2686 regarding lack of coverage of new-style classes have also been

2691================================
2692
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002693*Release date: 17-Jul-2008*
2694
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002695Core and Builtins
2696-----------------
2697
Georg Brandl3e483f62008-07-16 22:57:41 +00002698- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2699 its methods now allow for items objects that can be converted to
2700 an integer using operator.index().
2701
Mark Dickinson64b7e502008-07-16 09:40:03 +00002702- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2703 produced a ValueError instead of giving the correct float.
2704
Eric Smitha5fa5a22008-07-16 00:11:49 +00002705- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2706 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2707
Mark Dickinson7103aa42008-07-15 19:08:33 +00002708- Issue #3008: the float type has a new instance method 'float.hex'
2709 and a new class method 'float.fromhex' to convert floating-point
2710 numbers to and from hexadecimal strings, respectively.
2711
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002712- Issue #2235: __hash__ is once again inherited by default. To allow
2713 collections.Hashable to remain meaningful in the presence of the
2714 default hash implementation (object.__hash__), it is now possible
2715 to explicit block inheritance of hash by setting __hash__=None at
2716 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2717 level.
2718
Nick Coghlanb028f502008-07-13 14:52:36 +00002719- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2720 the parent module cannot be found while performing an absolute import.
2721 This means that an incorrectly defined __package__ attribute will
2722 now only prevent relative imports in that module rather than causing
2723 all imports from that module to fail.
2724
Nick Coghlan14ff9942008-07-08 14:21:42 +00002725- Issue #2517: Allow unicode messages in Exceptions again by correctly
2726 bypassing the instance dictionary when looking up __unicode__ on
2727 new-style classes.
2728
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002729- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2730 set to a custom object whose write() method happens to install
2731 another file in sys.stdout.
2732
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002733- Issue #3088: Corrected a race condition in classes derived from
2734 threading.local: the first member set by a thread could be saved in
2735 another thread's dictionary.
2736
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002737- Issue #3004: Minor change to slice.indices(): the start and stop
2738 arguments are now treated identically, making the behaviour easier
2739 to describe and understand. For example, slice(None, -10,
2740 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2741 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2742 10, -1).
2743
Georg Brandl278fc502008-07-19 12:46:12 +00002744- Issue #3219: Calling a function with repeated keyword arguments,
2745 f(a=2, a=23), would not cause a syntax error. This was a regression
2746 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002747
Georg Brandl278fc502008-07-19 12:46:12 +00002748- Issue #2862: Make int and float freelist management consistent with
2749 other freelists. Changes their CompactFreeList apis into
2750 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00002755- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2756 api functions without holding the GIL, which could lead to a fatal
2757 error when they failed.
2758
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002759- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Vinay Sajip51e65192008-07-18 09:01:10 +00002770- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002784- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2785 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002786 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002787 content-length. The problem had been corrected in the 2.4 branch, but never
2788 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002803- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2805
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002806- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3195 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003196 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003197
3198 This is controlled by the configure argument ``--with-universal-archs``:
3199
3200 - ``--with-universal-archs=all``: install 4-way universal
3201
3202 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3203
3204 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3205
3206 This option should be used in combination with ``--enable-universalsdk=``.
3207
3208 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 +00003258- Issue #1631171: Re-implement the 'warnings' module in C (the
3259 original Python code has been kept as backup). This will allow for
3260 using the 'warning's machinery in such places as the parser where
3261 use of pure Python code is not possible. Both the ``showarning()``
3262 and ``formatwarning()`` gain an optional 'line' argument which is
3263 not called by default for backwards-compatibility reasons. Setting
3264 ``warnings.showwarning()`` to an implementation that lacks support
3265 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003328- Issue #2550: The approach used by client/server code for obtaining
3329 ports to listen on in network-oriented tests has been refined in an
3330 effort to facilitate running multiple instances of the entire
3331 regression test suite in parallel without issue.
3332 test_support.bind_port() has been fixed such that it will always
3333 return a unique port -- which wasn't always the case with the
3334 previous implementation, especially if socket options had been set
3335 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3336 new implementation of bind_port() will actually raise an exception
3337 if it is passed an AF_INET/SOCK_STREAM socket with either the
3338 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3339 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3340 the socket it's been passed. This currently only applies to
3341 Windows. This option prevents any other sockets from binding to the
3342 host/port we've bound to, thus removing the possibility of the
3343 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3344 when a second SOCK_STREAM socket binds and accepts to a host/port
3345 that's already been bound by another socket. The optional preferred
3346 port parameter to bind_port() has been removed. Under no
3347 circumstances should tests be hard coding ports!
3348
3349 test_support.find_unused_port() has also been introduced, which will
3350 pass a temporary socket object to bind_port() in order to obtain an
3351 unused port. The temporary socket object is then closed and
3352 deleted, and the port is returned. This method should only be used
3353 for obtaining an unused port in order to pass to an external program
3354 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3355 a parameter to a server-oriented class that doesn't give you direct
3356 access to the underlying socket used.
3357
3358 Finally, test_support.HOST has been introduced, which should be used
3359 for the host argument of any relevant socket calls (i.e. bind and
3360 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003361
3362 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003363 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003364 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3365 test_asynchat and test_socket_ssl.
3366
Georg Brandl3ee81df2008-05-17 18:14:43 +00003367 It is now possible for multiple instances of the regression test
3368 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003422- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3424 Plane. This affected raw unicode literals and the
3425 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3426 this case, like normal unicode literals and the 'unicode-escape'
3427 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00003647- Added the future_builtins module, which contains hex() and oct().

3649 compatible with the hex() and oct() builtins from Python 3.0. They
3650 differ slightly in their output formats from the existing, unchanged
3651 Python 2.6 builtins. The expected usage of the future_builtins
3652 module is:
3653 from future_builtins import hex, oct

3656 exponents for exponents with absolute value < 100. Follows C99
3657 standard. This is a change on Windows, which would use 3 digits.
3658 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3659 so that any alterations it does to the resulting string will be
3660 available in stringlib/formatter.h (for float.__format__).
3661
Eric Smith5a3c1352008-02-19 13:21:56 +00003662- Implemented PEP 3101, Advanced String Formatting. This adds a new
3663 builtin format(); a format() method for str and unicode; a
3664 __format__() method to object, str, unicode, int, long, float, and
3665 datetime; the class string.Formatter; and the C API
3666 PyObject_Format().
3667
Georg Brandl3ee81df2008-05-17 18:14:43 +00003668- Fixed several potential crashes, all caused by specially crafted
3669 __del__ methods exploiting objects in temporarily inconsistent
3670 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003679- Clear all free lists during a gc.collect() of the highest generation
3680 in order to allow pymalloc to free more arenas. Python may give back
3681 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003682
Georg Brandl3ee81df2008-05-17 18:14:43 +00003683- Issue #2045: Fix an infinite recursion triggered when printing a
3684 subclass of collections.defaultdict, if its default_factory is set
3685 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00003687- Fixed a minor memory leak in dictobject.c. The content of the free
3688 list was not freed on interpreter shutdown.
3689
Georg Brandl3ee81df2008-05-17 18:14:43 +00003690- Limit free list of method and builtin function objects to 256
3691 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003692
Georg Brandl3ee81df2008-05-17 18:14:43 +00003693- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3694 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003695 to compact the internal free lists of pre-allocted ints and floats.
3696
Georg Brandl3ee81df2008-05-17 18:14:43 +00003697- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3698 calls. Python expected the return type int but the fork familie
3699 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003713- Patch #1473257: generator objects gain a gi_code attribute. This is
3714 the same object as the func_code attribute of the function that
3715 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003716
Georg Brandl3ee81df2008-05-17 18:14:43 +00003717- Issue #1920: "while 0" statements were completely removed by the
3718 compiler, even in the presence of an "else" clause, which is
3719 supposed to be run when the condition is false. Now the compiler
3720 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003721
Guido van Rossumeead05f2008-01-24 18:21:02 +00003722- A few crashers fixed: weakref_in_del.py (issue #1377858);
3723 loosing_dict_ref.py (issue #1303614, test67.py);
3724 borrowed_ref_[34].py (not in tracker).
3725
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003726- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003727 suppressed while an extension is loaded by calling SetErrorMode in
3728 dynload_win.c. The error is still reported properly.
3729
Georg Brandl3ee81df2008-05-17 18:14:43 +00003730- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003731 several extension methods and modules do not work without unicode
3732 support.
3733
Georg Brandl26543b12008-01-21 18:36:51 +00003734- Issue #1882: when compiling code from a string, encoding cookies in the

3738
Georg Brandl6caad7d2008-01-26 14:19:22 +00003739- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003740 added.
3741
Christian Heimesc94e2b52008-01-14 04:13:37 +00003742- sys.float_info / PyFloat_GetInfo: The floating point information
3743 object was converted from a dict to a specialized structseq object.
3744
Georg Brandl3ee81df2008-05-17 18:14:43 +00003745- Patch #1816: Added sys.flags structseq. It exposes the status of
3746 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003747
Georg Brandl3ee81df2008-05-17 18:14:43 +00003748- Objects/structseq.c: Implemented new structseq representation. The
3749 patch makes structseqs (e.g. the return value of os.stat) more
3750 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003751
Georg Brandl3ee81df2008-05-17 18:14:43 +00003752- Patch #1700288: added a type attribute cache that caches method
3753 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003754
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003755- Bug #1776: __import__() no longer accepts filenames on any platform.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Improve some exception messages when Windows fails to load an
3765 extension module. Now we get for example '%1 is not a valid Win32
3766 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003828- Issue #1686386: Tuple's tp_repr did not take into account the
3829 possibility of having a self-referential tuple, which is possible
3830 from C code. Nor did object's tp_str consider that a type's tp_str
3831 could do something that could lead to an inifinite recursion.
3832 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3833 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003834

3836 'print' statement to write to a file since the GIL was not released
3837 as needed. Now PyObject_Print() does the right thing along with
3838 various tp_print implementations of the built-in types and those in
3839 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003849 PyObject_Call() never calling back out to Python code to trigger
3850 recursion depth updates/checks. Required the creation of a static

Guido van Rossum143b5642007-03-23 04:58:42 +00003901- Bug #1683368: The object.__init__() and object.__new__() methods are
3902 now stricter in rejecting excess arguments. The only time when
3903 either allows excess arguments is when it is not overridden and the
3904 other one is. For backwards compatibility, when both are
3905 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003906 warning later). Also, type.__init__() insists on the same signature
3907 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3910 object to complex using its __complex__() method before falling back
3911 to the __float__() method. Therefore, the functions in the cmath
3912 module now can operate on objects that define a __complex__()
3913 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003931- Bug #1678647: write a newline after printing an exception in any
3932 case, even when converting the value to a string failed.
3933
Georg Brandl871f1bc2007-03-12 13:17:36 +00003934- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003935 its argument, if it exists. If not, it will work like before. This
3936 allows customizing the output of dir() in the presence of a
3937 __getattr__().

3947 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003948
Georg Brandlaa2321b2007-03-07 00:40:28 +00003949- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003950 makes the filenames the warning module prints much more sensible
3951 when a PYTHONSTARTUP file is used.

3965 sq_ass_slice instead of the sq_slice slot.
3966
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967- When printing an unraisable error, don't print exceptions. before
3968 the name. This duplicates the behavior whening normally printing
3969 exceptions.

Georg Brandl2c1375c2006-10-12 11:27:59 +00004019- Bug #1545497: when given an explicit base, int() did ignore NULs
4020 embedded in the string to convert.
4021
Georg Brandl846f73a2006-10-08 07:11:54 +00004022- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004070 generator expressions (x for x, in ... ) works again. Fixing this
4071 problem required changing the .pyc magic number. This means that
4072 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004875- The implementation of UnicodeError objects has been simplified
4876 (start and end attributes are now stored directly as Py_ssize_t
4877 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00004879- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4880 with RFC 3207 and forgets any knowledge obtained from the server not
4881 obtained from the TLS negotiation itself. Patch contributed by Bill
4882 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004883
Georg Brandl3ee81df2008-05-17 18:14:43 +00004884- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004885 that the SMTP.starttls() caller no longer needs to call ehlo()
4886 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004887 does not claim to support starttls. Adds the
4888 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4889 Fenner.

4969 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4970 silently miscode subclasses of those types. Now, it raises a
4971 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004972

Georg Brandl3ee81df2008-05-17 18:14:43 +00004987 time so that opening a database previously created with the DB_DUP
4988 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4989 opens. Specifically: dictionary assignment to a DB object will
4990 replace all values for a given key when the database allows
4991 duplicate values. DB users should use DB.put(k, v) when they want
4992 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004993

4999 characters with ASCII value less than 32. Also, it correctly quotes
5000 dots only if they occur on a single line, as opposed to the previous
5001 behavior of quoting dots if they are the second character of any
5002 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005003
