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

308 expected. These functions and methods now raise TypeError instead.
309 The majority of the effects of this change are in the extension

311 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
312 methods.

496
Mark Dickinsonb678de82009-11-19 18:41:49 +0000497- Issue #7117: repr(x) for a float x returns a result based on the
498 shortest decimal string that's guaranteed to round back to x under
499 correct rounding (with round-half-to-even rounding mode).
500 Previously it gave a string based on rounding x to 17 decimal digits.
501 repr(x) for a complex number behaves similarly. On platforms where
502 the correctly-rounded strtod and dtoa code is not supported (see below),
503 repr is unchanged.
504
505- Issue #7117: On almost all platforms: float-to-string and
506 string-to-float conversions within Python are now correctly rounded.
507 Places these conversions occur include: str for floats and complex
508 numbers; the float and complex constructors; old-style and new-style
509 numeric formatting; serialization and deserialization of floats and
510 complex numbers using marshal, pickle and json; parsing of float and
511 imaginary literals in Python code; Decimal-to-float conversion.
512
513 The conversions use a Python-adapted version of David Gay's
514 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
515 functions. This code is supported on Windows, and on Unix-like
516 platforms using gcc, icc or suncc as the C compiler. There may be a
517 small number of platforms on which correct operation of this code
518 cannot be guaranteed, so the code is not used: notably, this applies
519 to platforms where the C double format is not IEEE 754 binary64, and
520 to platforms on x86 hardware where the x87 FPU is set to 64-bit
521 precision and Python's configure script is unable to determine how
522 to change the FPU precision. On these platforms conversions use the
523 platform strtod and dtoa, as before.
524
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000525- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000526 now uses the correctly-rounded string <-> float conversions
527 described above (when available), and so produces correctly rounded
528 results that will display nicely under the float repr. There are
529 two related small changes: (1) round now accepts any class with an
530 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000531 floats for the second argument), and (2) an excessively large second
532 integer argument (e.g., round(1.234, 10**100)) no longer raises an
533 exception.

643
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000644- When no module is given in a relative import, the module field of the
645 ImportFrom AST node is now None instead of an empty string.
646
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000647- Assignment to None using import statements now raises a SyntaxError.
648

Antoine Pitrou46dbe272009-05-30 21:27:00 +0000654
Raymond Hettinger578a2282009-05-29 04:58:52 +0000655- Issue #5982: staticmethod and classmethod now expose the wrapped
656 function with __func__.
657
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000658- Added support for multiple context managers in the same with-statement.
659 Deprecated contextlib.nested() which is no longer needed.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000661- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
662 statement and correctly lookup the __enter__ and __exit__ special methods.
663
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000664- Issue #5829: complex("1e500") no longer raises OverflowError. This
665 makes it consistent with float("1e500") and interpretation of real
666 and imaginary literals.
667
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000668- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
669

R. David Murray525cffc2009-05-13 13:07:14 +0000673- Issue #5994: the marshal module now has docstrings.
674
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000675- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
676 (1) inf and nan strings with trailing whitespace were incorrectly
677 rejected; (2) parsing of strings representing infinities and nans
678 was locale aware; and (3) the interpretation of fromhex('-nan')
679 didn't match that of float('-nan').
680
Eric Smitha985a3a2009-05-05 18:26:08 +0000681- Issue #5920: For float.__format__, change the behavior with the
682 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
683 to be like 'g' but with at least one decimal point and with a
684 default precision of 12. Previously, the behavior the same but with
685 a default precision of 6. This more closely matches str(), and
686 reduces surprises when adding alignment flags to the empty
687 presentation type. This also affects the new complex.__format__ in
688 the same way.
689
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000690- Issue #5890: in subclasses of 'property' the __doc__ attribute was
691 shadowed by classtype's, even if it was None. property now
692 inserts the __doc__ into the subclass instance __dict__.
693
Antoine Pitrou653dece2009-05-04 18:32:32 +0000694- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

715 z involves nans, infs or negative zeros.
716
Eric Smithaca19e62009-04-22 13:29:05 +0000717- Implement PEP 378, Format Specifier for Thousands Separator, for
718 floats, ints, and longs.
719
720- Issue #5515: 'n' formatting for ints, longs, and floats handles
721 leading zero formatting poorly.
722
723- Issue #5772: For float.__format__, don't add a trailing ".0" if
724 we're using no type code and we have an exponent.
725

730 some builtin types.
731
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000732- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000733 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000734
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000735- Issue #5759: float() didn't call __float__ on str subclasses.

740 its clarity and its speed.
741

750 the end sys.path, for compatibility with the system install of Python.
751
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000752- Issue #4688: Add a heuristic so that tuples and dicts containing only
753 untrackable objects are not tracked by the garbage collector. This can
754 reduce the size of collections and therefore the garbage collection overhead
755 on long-running programs, depending on their particular use of datatypes.
756
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000757- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
758 improve its performance. Long divisions and remainder operations
759 are now between 50% and 150% faster.
760
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000761- Issue #4258: Make it possible to use base 2**30 instead of base
762 2**15 for the internal representation of integers, for performance
763 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
764 --enable-big-digits option to configure, which overrides the
765 default. Add sys.long_info structseq to provide information about
766 the internal format.
767
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000768- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
769 result traceback.__members__ no longer exists.)
770
Mark Dickinson6b265f12009-03-18 16:07:26 +0000771- Issue #4474: PyUnicode_FromWideChar now converts characters outside
772 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
773 and sizeof(Py_UNICODE) == 2.
774
Eric Smith6f42edb2009-03-14 11:57:26 +0000775- Issue #5237: Allow auto-numbered fields in str.format(). For
776 example: '{} {}'.format(1, 2) == '1 2'.
777
Brett Cannon6c4cff02009-03-11 04:51:06 +0000778- Issue #3652: Make the 'line' argument for warnings.showwarning() a
779 requirement. Means the DeprecationWarning from Python 2.6 can go away.
780
Eric Smithe9fb6862009-02-20 14:02:36 +0000781- Issue #5247: Improve error message when unknown format codes are
782 used when using str.format() with str, unicode, long, int, and
783 float arguments.
784
Raymond Hettinger08259e82009-02-18 23:10:19 +0000785- Running Python with the -3 option now also warns about classic division
786 for ints and longs.
787
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000788- Issue #5260: Long integers now consume less memory: average
789 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
790 on a 64-bit system.
791
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000792- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
793 rotating the object pointer by 4 bits to the right.
794
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000795- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
796 it now forces its argument to double before testing for infinity.
797
Benjamin Petersone18ef192009-01-20 14:21:16 +0000798- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
799
Georg Brandl29c6a282009-04-05 20:23:13 +0000800- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000801 were suppressing all exceptions. These include list(), filter(), map(),
802 zip(), and bytearray().
803
Benjamin Peterson596d3062009-01-19 15:42:23 +0000804- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
805 functions.
806
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000807- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

811
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000812- Issue #4935: The overflow checking code in the expandtabs() method common
813 to str, bytes and bytearray could be optimized away by the compiler, letting
814 the interpreter segfault instead of raising an error.

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000823- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
824 collecting the oldest generation) so that allocating lots of objects without
825 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000826 Martin von Löwis at

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000831- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
832 an existing .py counterpart, override the co_filename attributes of all
833 code objects if the original filename is obsolete (which can happen if the
834 file has been renamed, moved, or if it is accessed through different paths).
835 Patch by Ziga Seilnacht and Jean-Paul Calderone.

847
Benjamin Peterson7af65562008-12-29 17:56:58 +0000848- Issue #4764: With io.open, IOError.filename is set when trying to open a

876 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
877 str instances. On a typical machine this saves 3 bytes of memory
878 (on average) per string allocation.
879
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000880- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000891 method on file objects with closefd=False. The file descriptor is still
892 kept open but the file object behaves like a closed file. The ``FileIO``
893 object also got a new readonly attribute ``closefd``.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000916- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
917 returned a path longer than MAX_PATH. (But It's doubtful this code path is
918 really executed because I cannot move to such directory on win2k)
919
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000920- Issue #4069: When set.remove(element) is used with a set element, the element
921 is temporarily replaced with an equivalent frozenset. But the eventual
922 KeyError would always report the empty frozenset([]) as the missing key. Now
923 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000943- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
944 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
945 step. This avoids problems with counting UTF-8 bytes that ignores the effect
946 of using the replace error handler in PyUnicode_DecodeUTF8().
947
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000948- Issue #3739: The unicode-internal encoder now reports the number of characters
949 consumed like any other encoder (instead of the number of bytes).
950
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000951- Issue #2422: When compiled with the ``--with-valgrind`` option, the
952 pymalloc allocator will be automatically disabled when running under
953 Valgrind. This gives improved memory leak detection when running
954 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00001023- Issue #6816: runpy now provides a run_path function that allows Python code
1024 to execute file paths that refer to source or compiled Python files as well

2191 leak-chasing test runs give sensible results. The previous method of

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002334- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2335
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002336- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2337 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2338 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2339 ``printf`` function, whereas PyString_FromFormat has an independent
2340 implementation and uses "%zd" on all platforms for size_t values.
2341 This makes a difference on win64, where ``printf`` needs "%Id" to display
2342 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002344- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2348 object; previously an int would be returned for small values. the __long__
2349 method is allowed to return either an int or a long, but the behaviour of
2350 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002352- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002358 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002359 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002361- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002362 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2363 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2364 when given a tuple of classes as second argument, were looking up
2365 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2366 type object.

2437 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2438 for catch_warnings() also led to an improvement in the raising of a

2511-----------------
2512
Guido van Rossumf8402962008-08-20 15:01:50 +00002513- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2514 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2515 extensions do not automatically benefit from the class attribute
2516 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2517 to their tp_flags field if they care. This is a backwards
2518 compatibility feature; in 3.0, all types will use the cache by
2519 default.
2520
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002521- Keyword arguments can now follow starred arguments. (``f(a, *args,
2522 keyword=23)`` is now valid syntax.)
2523
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002524- ctypes function pointers that are COM methods have a boolean True
2525 value again.
2526
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002527- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2528 by denying s# to parse objects that have a releasebuffer procedure,
2529 and introducing s*.
2530
Georg Brandl1e13ea92008-08-11 09:07:59 +00002531- Issue #3537: Fix an assertion failure when an empty but presized dict
2532 object was stored in the freelist.
2533
Mark Dickinsonb6467572008-08-04 21:30:09 +00002534- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2535 ValueError consistently across platforms.
2536
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002537- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2538 (64bit Unix, for example), unichr() would truncate its argument and return
2539 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2540
Neal Norwitze7d8be82008-07-31 17:17:14 +00002541- Apply security patches from Apple.
2542
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002543- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2544 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2545
Antoine Pitrou92f82162008-07-25 22:22:08 +00002546- Issue #1819: function calls with several named parameters are now on
2547 average 35% faster (as measured by pybench).
2548
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002549- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2550 the python debugger steps into a class statement: the free variables (local
2551 variables defined in an outer scope) would be deleted from the outer scope.
2552
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002553- Issue #2620: Overflow checking when allocating or reallocating memory
2554 was not always being done properly in some python types and extension
2555 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2556 all been updated to perform better checks and places in the code that
2557 would previously leak memory on the error path when such an allocation
2558 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002563- Issue #3612: Added some missing basic types in ctypes.wintypes.
2564
Benjamin Petersone977ad42008-08-20 01:42:01 +00002565- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2566 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2567
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002568- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2569 version reported by these tools does not necessarily follow the python
2570 version numbering scheme, so the module is less strict when parsing it.
2571
Nick Coghlanf70385a2008-08-18 12:42:46 +00002572- Issue #2235: Added Py3k warnings for types which will become unhashable
2573 under the stricter __hash__ inheritance rules in 3.0. Several types
2574 which did not meet the rules for hash invariants and were already
2575 unhashable in 3.0 have now been explicitly flagged as unhashable in
2576 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2577 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2578
Brett Cannon88f801d2008-08-18 00:46:22 +00002579- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2580 imported into the module but exposed as part of the module's API.
2581
Brett Cannon7b96f072008-08-18 00:41:11 +00002582- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2583
Brett Cannon46225e72008-08-18 00:36:52 +00002584- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2587
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002588- Issue #3575: Incremental decoder's decode function now takes bytearray
2589 by using 's*' instead of 't#'.
2590
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002591- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002592 fails unicode conversion on 2nd parameter. (windows only)
2593
Facundo Batista94f243a2008-08-17 03:38:39 +00002594- Issue 2464. urllib2 now supports a malformation in the URL received
2595 in a redirect.
2596
Brett Cannonabe423e2008-08-16 21:47:07 +00002597- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002598 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002599
Facundo Batistaeb90b782008-08-16 14:44:07 +00002600- Issue #2776: fixed small issue when handling an URL with double slash
2601 after a 302 response in the case of not going through a proxy.
2602
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002603- Issue #2676: in the email package, content-type parsing was hanging on
2604 pathological input because of quadratic or exponential behaviour of a
2605 regular expression.
2606
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002607- Issue #3476: binary buffered reading through the new "io" library is now
2608 thread-safe.
2609
Brett Cannonbf3157b2008-08-14 05:00:03 +00002610- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2611 since mimetools itself is deprecated. Because modules are cached, all
2612 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2613
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002614- Issue #3134: shutil referenced undefined WindowsError symbol.
2615
Robert Schuppenies14646332008-08-10 11:01:53 +00002616- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2617 menu entries were not deleted.
2618
Brett Cannon83e81842008-08-09 23:30:55 +00002619- Copied the implementation of reduce() to _functools.reduce() to have a
2620 version that did not raise a DeprecationWarning under -3.
2621
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002622- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2623 a MemoryError rather than silently stop the iteration.
2624
Guido van Rossum59ce9012008-08-09 14:55:34 +00002625- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2626 to _sre.compile() will now be rejected. This should not affect anybody
2627 since the re.compile() function never generates invalid re-bytecode.
2628
Skip Montanaroa032bf42008-08-08 22:52:51 +00002629- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2630 upon first access it can be automatically initialized from the csv file if
2631 it wasn't initialized during instantiation.
2632
Brett Cannon3aa2a492008-08-06 22:28:09 +00002633- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2634 the reload() built-in has been removed.
2635
Brett Cannon7e30b672008-08-04 21:52:25 +00002636- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002637 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2645 raised an AttributeError.
2646
Benjamin Peterson01a24322008-07-28 23:35:27 +00002647- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002648 asking for a specific length. This problem only affected files opened
2649 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002650
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002651- Issue #3449: Update decimal module to use most recent specification
2652 (v. 1.68) and tests (v. 2.58) from IBM.
2653

2673
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002674- Issue #3394: zipfile.writestr sets external attributes when passed a
2675 file name rather than a ZipInfo instance, so files are extracted with
2676 mode 0600 rather than 000 under Unix.
2677
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002678- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2679 argument in python 2.5, this broke code that subclassed Popen to include its
2680 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002690- Issue #2235: the C API function PyObject_HashNotImplemented and its
2691 interaction with the tp_hash slot (added in 2.6b2) are now documented
2692
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002693- Issue #643841: The language reference now provides more detailed
2694 coverage of the lookup process for special methods. The disclaimers
2695 regarding lack of coverage of new-style classes have also been
2696 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002699What's New in Python 2.6 beta 2?
2700================================
2701
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002702*Release date: 17-Jul-2008*
2703
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002704Core and Builtins
2705-----------------
2706
Georg Brandl3e483f62008-07-16 22:57:41 +00002707- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2708 its methods now allow for items objects that can be converted to
2709 an integer using operator.index().
2710
Mark Dickinson64b7e502008-07-16 09:40:03 +00002711- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2712 produced a ValueError instead of giving the correct float.
2713
Eric Smitha5fa5a22008-07-16 00:11:49 +00002714- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2715 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2716
Mark Dickinson7103aa42008-07-15 19:08:33 +00002717- Issue #3008: the float type has a new instance method 'float.hex'
2718 and a new class method 'float.fromhex' to convert floating-point
2719 numbers to and from hexadecimal strings, respectively.
2720
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002721- Issue #2235: __hash__ is once again inherited by default. To allow
2722 collections.Hashable to remain meaningful in the presence of the
2723 default hash implementation (object.__hash__), it is now possible
2724 to explicit block inheritance of hash by setting __hash__=None at
2725 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2726 level.
2727
Nick Coghlanb028f502008-07-13 14:52:36 +00002728- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2729 the parent module cannot be found while performing an absolute import.
2730 This means that an incorrectly defined __package__ attribute will
2731 now only prevent relative imports in that module rather than causing
2732 all imports from that module to fail.
2733
Nick Coghlan14ff9942008-07-08 14:21:42 +00002734- Issue #2517: Allow unicode messages in Exceptions again by correctly
2735 bypassing the instance dictionary when looking up __unicode__ on
2736 new-style classes.
2737
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002738- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2739 set to a custom object whose write() method happens to install
2740 another file in sys.stdout.
2741
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002742- Issue #3088: Corrected a race condition in classes derived from
2743 threading.local: the first member set by a thread could be saved in
2744 another thread's dictionary.
2745
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002746- Issue #3004: Minor change to slice.indices(): the start and stop
2747 arguments are now treated identically, making the behaviour easier
2748 to describe and understand. For example, slice(None, -10,
2749 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2750 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2751 10, -1).
2752
Georg Brandl278fc502008-07-19 12:46:12 +00002753- Issue #3219: Calling a function with repeated keyword arguments,
2754 f(a=2, a=23), would not cause a syntax error. This was a regression
2755 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002756
Georg Brandl278fc502008-07-19 12:46:12 +00002757- Issue #2862: Make int and float freelist management consistent with
2758 other freelists. Changes their CompactFreeList apis into
2759 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002760

2762-------
2763
Thomas Heller57adf222008-08-14 19:10:48 +00002764- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2765 api functions without holding the GIL, which could lead to a fatal
2766 error when they failed.
2767
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002768- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
2769

Jesse Noller13e9d582008-07-16 14:32:36 +00002776- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2777 ForkingPickler.register() to resolve conflict with ctypes.
2778
Vinay Sajip51e65192008-07-18 09:01:10 +00002779- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002780
Thomas Heller880f5292008-07-15 19:39:38 +00002781- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2782 a valid dlerror() message.
2783
Thomas Heller2bad6572008-07-15 17:19:50 +00002784- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2785 incomplete structure was created.
2786

2790
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002791- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002792
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002793- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2794 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002795 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002796 content-length. The problem had been corrected in the 2.4 branch, but never
2797 merged into trunk.
2798
Georg Brandle78fbcc2008-07-05 10:13:36 +00002799- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00002811
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002812- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2813 handling is now the same as that of other special attributes like __name__).
2814
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002815- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2816 removal in Python 3.0 in favor of urllib2.urlopen().

2827 default https port (443).
2828
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00002829- Issue #874900: after an os.fork() call the threading module state is cleaned

3204 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003205 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003206
3207 This is controlled by the configure argument ``--with-universal-archs``:
3208
3209 - ``--with-universal-archs=all``: install 4-way universal
3210
3211 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3212
3213 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3214
3215 This option should be used in combination with ``--enable-universalsdk=``.
3216
3217 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 +00003267- Issue #1631171: Re-implement the 'warnings' module in C (the
3268 original Python code has been kept as backup). This will allow for
3269 using the 'warning's machinery in such places as the parser where
3270 use of pure Python code is not possible. Both the ``showarning()``
3271 and ``formatwarning()`` gain an optional 'line' argument which is
3272 not called by default for backwards-compatibility reasons. Setting
3273 ``warnings.showwarning()`` to an implementation that lacks support
3274 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003337- Issue #2550: The approach used by client/server code for obtaining
3338 ports to listen on in network-oriented tests has been refined in an
3339 effort to facilitate running multiple instances of the entire
3340 regression test suite in parallel without issue.
3341 test_support.bind_port() has been fixed such that it will always
3342 return a unique port -- which wasn't always the case with the
3343 previous implementation, especially if socket options had been set
3344 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3345 new implementation of bind_port() will actually raise an exception
3346 if it is passed an AF_INET/SOCK_STREAM socket with either the
3347 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3348 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3349 the socket it's been passed. This currently only applies to
3350 Windows. This option prevents any other sockets from binding to the
3351 host/port we've bound to, thus removing the possibility of the
3352 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3353 when a second SOCK_STREAM socket binds and accepts to a host/port
3354 that's already been bound by another socket. The optional preferred
3355 port parameter to bind_port() has been removed. Under no
3356 circumstances should tests be hard coding ports!
3357
3358 test_support.find_unused_port() has also been introduced, which will
3359 pass a temporary socket object to bind_port() in order to obtain an
3360 unused port. The temporary socket object is then closed and
3361 deleted, and the port is returned. This method should only be used
3362 for obtaining an unused port in order to pass to an external program
3363 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3364 a parameter to a server-oriented class that doesn't give you direct
3365 access to the underlying socket used.
3366
3367 Finally, test_support.HOST has been introduced, which should be used
3368 for the host argument of any relevant socket calls (i.e. bind and
3369 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003370
3371 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003372 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003373 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3374 test_asynchat and test_socket_ssl.
3375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376 It is now possible for multiple instances of the regression test
3377 suite to run in parallel without issue.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003653- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003654 issue 215555 for a discussion.
3655
Eric Smitha73fbe72008-02-23 03:09:44 +00003656- Added the future_builtins module, which contains hex() and oct().
3657 These are the PEP 3127 version of these functions, designed to be
3658 compatible with the hex() and oct() builtins from Python 3.0. They
3659 differ slightly in their output formats from the existing, unchanged
3660 Python 2.6 builtins. The expected usage of the future_builtins
3661 module is:
3662 from future_builtins import hex, oct
3663
Eric Smith7ef40bf2008-02-20 23:34:22 +00003664- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3665 exponents for exponents with absolute value < 100. Follows C99
3666 standard. This is a change on Windows, which would use 3 digits.
3667 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3668 so that any alterations it does to the resulting string will be
3669 available in stringlib/formatter.h (for float.__format__).
3670
Eric Smith5a3c1352008-02-19 13:21:56 +00003671- Implemented PEP 3101, Advanced String Formatting. This adds a new
3672 builtin format(); a format() method for str and unicode; a
3673 __format__() method to object, str, unicode, int, long, float, and
3674 datetime; the class string.Formatter; and the C API
3675 PyObject_Format().
3676
Georg Brandl3ee81df2008-05-17 18:14:43 +00003677- Fixed several potential crashes, all caused by specially crafted
3678 __del__ methods exploiting objects in temporarily inconsistent
3679 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003680
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003681- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003682 prevent a possible crash: an Abstract Base Class would try to access
3683 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003684
Georg Brandl3ee81df2008-05-17 18:14:43 +00003685- Fixed repr() and str() of complex numbers with infinity or nan as
3686 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003687
Georg Brandl3ee81df2008-05-17 18:14:43 +00003688- Clear all free lists during a gc.collect() of the highest generation
3689 in order to allow pymalloc to free more arenas. Python may give back
3690 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003691
Georg Brandl3ee81df2008-05-17 18:14:43 +00003692- Issue #2045: Fix an infinite recursion triggered when printing a
3693 subclass of collections.defaultdict, if its default_factory is set
3694 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003695
Christian Heimesf75dbef2008-02-08 00:11:31 +00003696- Fixed a minor memory leak in dictobject.c. The content of the free
3697 list was not freed on interpreter shutdown.
3698
Georg Brandl3ee81df2008-05-17 18:14:43 +00003699- Limit free list of method and builtin function objects to 256
3700 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003701
Georg Brandl3ee81df2008-05-17 18:14:43 +00003702- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3703 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003704 to compact the internal free lists of pre-allocted ints and floats.
3705
Georg Brandl3ee81df2008-05-17 18:14:43 +00003706- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3707 calls. Python expected the return type int but the fork familie
3708 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003709
Georg Brandl3ee81df2008-05-17 18:14:43 +00003710- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3711 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003712
Georg Brandl3ee81df2008-05-17 18:14:43 +00003713- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3714 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003715
Georg Brandl3ee81df2008-05-17 18:14:43 +00003716- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3717 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003718
Georg Brandl3ee81df2008-05-17 18:14:43 +00003719- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3720 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003721
Georg Brandl3ee81df2008-05-17 18:14:43 +00003722- Patch #1473257: generator objects gain a gi_code attribute. This is
3723 the same object as the func_code attribute of the function that
3724 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003725
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726- Issue #1920: "while 0" statements were completely removed by the
3727 compiler, even in the presence of an "else" clause, which is
3728 supposed to be run when the condition is false. Now the compiler
3729 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003730
Guido van Rossumeead05f2008-01-24 18:21:02 +00003731- A few crashers fixed: weakref_in_del.py (issue #1377858);
3732 loosing_dict_ref.py (issue #1303614, test67.py);
3733 borrowed_ref_[34].py (not in tracker).
3734
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003735- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003736 suppressed while an extension is loaded by calling SetErrorMode in
3737 dynload_win.c. The error is still reported properly.
3738
Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003740 several extension methods and modules do not work without unicode
3741 support.
3742
Georg Brandl26543b12008-01-21 18:36:51 +00003743- Issue #1882: when compiling code from a string, encoding cookies in the
3744 second line of code were not always recognized correctly.
3745
Georg Brandl14404b62008-01-19 19:27:05 +00003746- Issue #1679: "0x" was taken as a valid integer literal.
3747
Georg Brandl6caad7d2008-01-26 14:19:22 +00003748- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003749 added.
3750
Christian Heimesc94e2b52008-01-14 04:13:37 +00003751- sys.float_info / PyFloat_GetInfo: The floating point information
3752 object was converted from a dict to a specialized structseq object.
3753
Georg Brandl3ee81df2008-05-17 18:14:43 +00003754- Patch #1816: Added sys.flags structseq. It exposes the status of
3755 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757- Objects/structseq.c: Implemented new structseq representation. The
3758 patch makes structseqs (e.g. the return value of os.stat) more
3759 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003760
Georg Brandl3ee81df2008-05-17 18:14:43 +00003761- Patch #1700288: added a type attribute cache that caches method
3762 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003763
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003764- Bug #1776: __import__() no longer accepts filenames on any platform.
3765 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003766
Georg Brandlaed6c662008-01-07 17:25:53 +00003767- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3768
Georg Brandl3ee81df2008-05-17 18:14:43 +00003769- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3770 envvar and sys.dont_write_bytecode attribute. All these can be set
3771 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003772
Georg Brandl3ee81df2008-05-17 18:14:43 +00003773- Improve some exception messages when Windows fails to load an
3774 extension module. Now we get for example '%1 is not a valid Win32
3775 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003776
Georg Brandl3ee81df2008-05-17 18:14:43 +00003777- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003779- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3780 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003781
Christian Heimes0a8143f2007-12-18 23:22:54 +00003782- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003783 and INF. float("nan"), float("inf") and float("-inf") now work on
3784 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003785
Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Compiler now generates simpler and faster code for dictionary
3787 literals. The oparg for BUILD_MAP now indicates an estimated
3788 dictionary size. There is a new opcode, STORE_MAP, for adding
3789 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003790
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791- Issue #1638: %zd configure test fails on Linux.

3819 file can now be directly executed by passing their name to the
3820 interpreter. The directory/zipfile is automatically inserted as the
3821 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003822
Georg Brandl3ee81df2008-05-17 18:14:43 +00003823- Issue #1265: Fix a problem with sys.settrace, if the tracing
3824 function uses a generator expression when at the same time the
3825 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003826
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003827- sets and frozensets now have an isdisjoint() method.
3828

3832
Georg Brandl3ee81df2008-05-17 18:14:43 +00003833- The enumerate() builtin function is no longer bounded to sequences
3834 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3835 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Issue #1686386: Tuple's tp_repr did not take into account the
3838 possibility of having a self-referential tuple, which is possible
3839 from C code. Nor did object's tp_str consider that a type's tp_str
3840 could do something that could lead to an inifinite recursion.
3841 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3842 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003843
Georg Brandl3ee81df2008-05-17 18:14:43 +00003844- Issue #1164: It was possible to trigger deadlock when using the
3845 'print' statement to write to a file since the GIL was not released
3846 as needed. Now PyObject_Print() does the right thing along with
3847 various tp_print implementations of the built-in types and those in
3848 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003849
Georg Brandl3ee81df2008-05-17 18:14:43 +00003850- Issue #1147: Exceptions were directly allowing string exceptions in
3851 their throw() method even though string exceptions no longer
3852 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003853

Brett Cannon1e534b52007-09-07 04:18:30 +00003857- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858 PyObject_Call() never calling back out to Python code to trigger
3859 recursion depth updates/checks. Required the creation of a static
3860 RuntimeError instance in case normalizing an exception put the
3861 recursion check value past its limit. Fixes crashers
3862 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003863
Georg Brandl3ee81df2008-05-17 18:14:43 +00003864- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003877- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878 __*__ attributes. (Some already existed, e.g., __doc__ and
3879 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003880
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003881- Add -3 option to the interpreter to warn about features that are
3882 deprecated and will be changed/removed in Python 3.0.
3883
Georg Brandl2134e752007-05-21 20:34:16 +00003884- Patch #1686487: you can now pass any mapping after '**' in function
3885 calls.
3886
Collin Winter62903052007-05-18 23:11:24 +00003887- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003888 "except E as target:". This is to provide forwards compatibility
3889 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003896- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003897 setting a plain string, ie don't expand to single letter identifiers.

3902 translations that only remove characters without re-mapping the
3903 remaining characters.
3904
Georg Brandl5cb76c12007-03-21 09:00:39 +00003905- Patch #1682205: a TypeError while unpacking an iterable is no longer

3909
Guido van Rossum143b5642007-03-23 04:58:42 +00003910- Bug #1683368: The object.__init__() and object.__new__() methods are
3911 now stricter in rejecting excess arguments. The only time when
3912 either allows excess arguments is when it is not overridden and the
3913 other one is. For backwards compatibility, when both are
3914 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003915 warning later). Also, type.__init__() insists on the same signature
3916 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003918- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3919 object to complex using its __complex__() method before falling back
3920 to the __float__() method. Therefore, the functions in the cmath
3921 module now can operate on objects that define a __complex__()
3922 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003940- Bug #1678647: write a newline after printing an exception in any
3941 case, even when converting the value to a string failed.
3942
Georg Brandl871f1bc2007-03-12 13:17:36 +00003943- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003944 its argument, if it exists. If not, it will work like before. This
3945 allows customizing the output of dir() in the presence of a
3946 __getattr__().

3956 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003957
Georg Brandlaa2321b2007-03-07 00:40:28 +00003958- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003959 makes the filenames the warning module prints much more sensible
3960 when a PYTHONSTARTUP file is used.

3974 sq_ass_slice instead of the sq_slice slot.
3975
Georg Brandl3ee81df2008-05-17 18:14:43 +00003976- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00004028- Bug #1545497: when given an explicit base, int() did ignore NULs
4029 embedded in the string to convert.
4030
Georg Brandl846f73a2006-10-08 07:11:54 +00004031- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004079 generator expressions (x for x, in ... ) works again. Fixing this
4080 problem required changing the .pyc magic number. This means that
4081 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004511 AttributeError instead of an IOError when the server's response
4512 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004513

4544
Georg Brandl92a6bae2007-03-13 17:43:32 +00004545- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004546 are set for invalid interpolation sequences that would lead to
4547 errors on reading back those values.

4601
Georg Brandl3ee81df2008-05-17 18:14:43 +00004602- unittest now verifies more of its assumptions. In particular,
4603 TestCase and TestSuite subclasses (not instances) are no longer
4604 accepted in TestSuite.addTest(). This should cause no
4605 incompatibility since it never made sense with ordinary subclasses
4606 -- the failure just occurred later, with a more cumbersome
4607 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004884- The implementation of UnicodeError objects has been simplified
4885 (start and end attributes are now stored directly as Py_ssize_t
4886 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004887
Georg Brandl3ee81df2008-05-17 18:14:43 +00004888- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4889 with RFC 3207 and forgets any knowledge obtained from the server not
4890 obtained from the TLS negotiation itself. Patch contributed by Bill
4891 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004892
Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004894 that the SMTP.starttls() caller no longer needs to call ehlo()
4895 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004896 does not claim to support starttls. Adds the
4897 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4898 Fenner.

4978 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4979 silently miscode subclasses of those types. Now, it raises a
4980 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004981

Georg Brandl3ee81df2008-05-17 18:14:43 +00004996 time so that opening a database previously created with the DB_DUP
4997 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4998 opens. Specifically: dictionary assignment to a DB object will
4999 replace all values for a given key when the database allows
5000 duplicate values. DB users should use DB.put(k, v) when they want
5001 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005002

5008 characters with ASCII value less than 32. Also, it correctly quotes
5009 dots only if they occur on a single line, as opposed to the previous
5010 behavior of quoting dots if they are the second character of any
5011 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005012

Georg Brandl3ee81df2008-05-17 18:14:43 +00005417- Removed the macfs module. It had been deprecated since Python 2.5.
5418 This lead to the deprecation of macostools.touched() as it relied
5419 solely on macfs and was a no-op under OS X.
