Mark Dickinson1b34d252010-01-01 17:27:30 +0000315- Issue #5080: A number of functions and methods previously produced a

317 expected. These functions and methods now raise TypeError instead.
318 The majority of the effects of this change are in the extension
319 modules, but some core functions and methods are affected: notably
320 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
321 methods.

505
Mark Dickinsonb678de82009-11-19 18:41:49 +0000506- Issue #7117: repr(x) for a float x returns a result based on the
507 shortest decimal string that's guaranteed to round back to x under
508 correct rounding (with round-half-to-even rounding mode).
509 Previously it gave a string based on rounding x to 17 decimal digits.
510 repr(x) for a complex number behaves similarly. On platforms where
511 the correctly-rounded strtod and dtoa code is not supported (see below),
512 repr is unchanged.
513
514- Issue #7117: On almost all platforms: float-to-string and
515 string-to-float conversions within Python are now correctly rounded.
516 Places these conversions occur include: str for floats and complex
517 numbers; the float and complex constructors; old-style and new-style
518 numeric formatting; serialization and deserialization of floats and
519 complex numbers using marshal, pickle and json; parsing of float and
520 imaginary literals in Python code; Decimal-to-float conversion.
521
522 The conversions use a Python-adapted version of David Gay's
523 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
524 functions. This code is supported on Windows, and on Unix-like
525 platforms using gcc, icc or suncc as the C compiler. There may be a
526 small number of platforms on which correct operation of this code
527 cannot be guaranteed, so the code is not used: notably, this applies
528 to platforms where the C double format is not IEEE 754 binary64, and
529 to platforms on x86 hardware where the x87 FPU is set to 64-bit
530 precision and Python's configure script is unable to determine how
531 to change the FPU precision. On these platforms conversions use the
532 platform strtod and dtoa, as before.
533
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000534- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000535 now uses the correctly-rounded string <-> float conversions
536 described above (when available), and so produces correctly rounded
537 results that will display nicely under the float repr. There are
538 two related small changes: (1) round now accepts any class with an
539 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000540 floats for the second argument), and (2) an excessively large second
541 integer argument (e.g., round(1.234, 10**100)) no longer raises an
542 exception.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000670- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
671 statement and correctly lookup the __enter__ and __exit__ special methods.
672
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000673- Issue #5829: complex("1e500") no longer raises OverflowError. This
674 makes it consistent with float("1e500") and interpretation of real
675 and imaginary literals.
676

683
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000684- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
685 (1) inf and nan strings with trailing whitespace were incorrectly
686 rejected; (2) parsing of strings representing infinities and nans
687 was locale aware; and (3) the interpretation of fromhex('-nan')
688 didn't match that of float('-nan').
689
Eric Smitha985a3a2009-05-05 18:26:08 +0000690- Issue #5920: For float.__format__, change the behavior with the
691 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
692 to be like 'g' but with at least one decimal point and with a
693 default precision of 12. Previously, the behavior the same but with
694 a default precision of 6. This more closely matches str(), and
695 reduces surprises when adding alignment flags to the empty
696 presentation type. This also affects the new complex.__format__ in
697 the same way.
698
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000699- Issue #5890: in subclasses of 'property' the __doc__ attribute was
700 shadowed by classtype's, even if it was None. property now
701 inserts the __doc__ into the subclass instance __dict__.
702

727 floats, ints, and longs.
728
729- Issue #5515: 'n' formatting for ints, longs, and floats handles
730 leading zero formatting poorly.
731
732- Issue #5772: For float.__format__, don't add a trailing ".0" if
733 we're using no type code and we have an exponent.
734

739 some builtin types.
740
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000741- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000742 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000743
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000744- Issue #5759: float() didn't call __float__ on str subclasses.

759 the end sys.path, for compatibility with the system install of Python.
760
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000761- Issue #4688: Add a heuristic so that tuples and dicts containing only
762 untrackable objects are not tracked by the garbage collector. This can
763 reduce the size of collections and therefore the garbage collection overhead
764 on long-running programs, depending on their particular use of datatypes.
765
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000766- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

768 are now between 50% and 150% faster.
769
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000770- Issue #4258: Make it possible to use base 2**30 instead of base
771 2**15 for the internal representation of integers, for performance
772 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
773 --enable-big-digits option to configure, which overrides the
774 default. Add sys.long_info structseq to provide information about
775 the internal format.
776
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000777- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
778 result traceback.__members__ no longer exists.)
779
Mark Dickinson6b265f12009-03-18 16:07:26 +0000780- Issue #4474: PyUnicode_FromWideChar now converts characters outside
781 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

783
Eric Smith6f42edb2009-03-14 11:57:26 +0000784- Issue #5237: Allow auto-numbered fields in str.format(). For
785 example: '{} {}'.format(1, 2) == '1 2'.
786
Brett Cannon6c4cff02009-03-11 04:51:06 +0000787- Issue #3652: Make the 'line' argument for warnings.showwarning() a
788 requirement. Means the DeprecationWarning from Python 2.6 can go away.
789
Eric Smithe9fb6862009-02-20 14:02:36 +0000790- Issue #5247: Improve error message when unknown format codes are
791 used when using str.format() with str, unicode, long, int, and
792 float arguments.
793
Raymond Hettinger08259e82009-02-18 23:10:19 +0000794- Running Python with the -3 option now also warns about classic division
795 for ints and longs.
796
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000797- Issue #5260: Long integers now consume less memory: average
798 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
799 on a 64-bit system.
800
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000801- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
802 rotating the object pointer by 4 bits to the right.
803
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000804- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
805 it now forces its argument to double before testing for infinity.
806
Benjamin Petersone18ef192009-01-20 14:21:16 +0000807- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
808
Georg Brandl29c6a282009-04-05 20:23:13 +0000809- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000810 were suppressing all exceptions. These include list(), filter(), map(),
811 zip(), and bytearray().
812
Benjamin Peterson596d3062009-01-19 15:42:23 +0000813- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
814 functions.
815

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000832- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
833 collecting the oldest generation) so that allocating lots of objects without
834 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000835 Martin von Löwis at

841 an existing .py counterpart, override the co_filename attributes of all
842 code objects if the original filename is obsolete (which can happen if the
843 file has been renamed, moved, or if it is accessed through different paths).
844 Patch by Ziga Seilnacht and Jean-Paul Calderone.

927 really executed because I cannot move to such directory on win2k)
928
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000929- Issue #4069: When set.remove(element) is used with a set element, the element

932 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000952- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
953 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
954 step. This avoids problems with counting UTF-8 bytes that ignores the effect
955 of using the replace error handler in PyUnicode_DecodeUTF8().
956
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000957- Issue #3739: The unicode-internal encoder now reports the number of characters

962 Valgrind. This gives improved memory leak detection when running
963 under Valgrind, while taking advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002343- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2344
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002345- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2346 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2347 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2348 ``printf`` function, whereas PyString_FromFormat has an independent
2349 implementation and uses "%zd" on all platforms for size_t values.
2350 This makes a difference on win64, where ``printf`` needs "%Id" to display
2351 64bit values.
2352
Benjamin Peterson97179b02008-09-09 20:55:01 +00002353- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2357 object; previously an int would be returned for small values. the __long__
2358 method is allowed to return either an int or a long, but the behaviour of
2359 float objects should not change to respect backward compatibility.
2360
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002361- Issue #3751: str.rpartition would perform a left-partition when called with
2362 a unicode argument.
2363
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002364- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002367 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002368 was correctly parsed but parsing of subsequent arguments failed.
2369
Vinay Sajip35e3b032008-09-01 14:33:59 +00002370- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002371 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2372 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2373 when given a tuple of classes as second argument, were looking up
2374 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2375 type object.
2376
Neal Norwitz18aa3882008-08-24 05:04:52 +00002377- Fix crashes on memory allocation failure found with failmalloc.
2378
2379- Fix memory leaks found with valgrind and update suppressions file.
2380
2381- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2382
2383- Fix problem using wrong name in decimal module reported by pychecker.

Nick Coghland2e09382008-09-11 12:11:06 +00002419- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002420 return a list or None rather than a custom object.

2446 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2447 for catch_warnings() also led to an improvement in the raising of a
2448 DeprecationWarning related to warnings.warn_explicit().

2520-----------------
2521
Guido van Rossumf8402962008-08-20 15:01:50 +00002522- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2523 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2524 extensions do not automatically benefit from the class attribute
2525 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2526 to their tp_flags field if they care. This is a backwards
2527 compatibility feature; in 3.0, all types will use the cache by
2528 default.
2529
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002530- Keyword arguments can now follow starred arguments. (``f(a, *args,
2531 keyword=23)`` is now valid syntax.)
2532
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002533- ctypes function pointers that are COM methods have a boolean True
2534 value again.
2535
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002536- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2537 by denying s# to parse objects that have a releasebuffer procedure,
2538 and introducing s*.
2539
Georg Brandl1e13ea92008-08-11 09:07:59 +00002540- Issue #3537: Fix an assertion failure when an empty but presized dict
2541 object was stored in the freelist.
2542
Mark Dickinsonb6467572008-08-04 21:30:09 +00002543- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2544 ValueError consistently across platforms.
2545
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002546- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2547 (64bit Unix, for example), unichr() would truncate its argument and return
2548 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2549
Neal Norwitze7d8be82008-07-31 17:17:14 +00002550- Apply security patches from Apple.
2551
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002552- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00002555- Issue #1819: function calls with several named parameters are now on
2556 average 35% faster (as measured by pybench).
2557
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002558- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2559 the python debugger steps into a class statement: the free variables (local
2560 variables defined in an outer scope) would be deleted from the outer scope.
2561
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002562- Issue #2620: Overflow checking when allocating or reallocating memory
2563 was not always being done properly in some python types and extension
2564 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2565 all been updated to perform better checks and places in the code that
2566 would previously leak memory on the error path when such an allocation
2567 failed have been fixed.

2573
Benjamin Petersone977ad42008-08-20 01:42:01 +00002574- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2575 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2576
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002577- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2578 version reported by these tools does not necessarily follow the python
2579 version numbering scheme, so the module is less strict when parsing it.
2580
Nick Coghlanf70385a2008-08-18 12:42:46 +00002581- Issue #2235: Added Py3k warnings for types which will become unhashable
2582 under the stricter __hash__ inheritance rules in 3.0. Several types
2583 which did not meet the rules for hash invariants and were already
2584 unhashable in 3.0 have now been explicitly flagged as unhashable in
2585 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2586 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2587
Brett Cannon88f801d2008-08-18 00:46:22 +00002588- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2589 imported into the module but exposed as part of the module's API.
2590

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002597- Issue #3575: Incremental decoder's decode function now takes bytearray
2598 by using 's*' instead of 't#'.
2599
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002600- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002601 fails unicode conversion on 2nd parameter. (windows only)
2602
Facundo Batista94f243a2008-08-17 03:38:39 +00002603- Issue 2464. urllib2 now supports a malformation in the URL received
2604 in a redirect.

2610 after a 302 response in the case of not going through a proxy.
2611
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002612- Issue #2676: in the email package, content-type parsing was hanging on
2613 pathological input because of quadratic or exponential behaviour of a
2614 regular expression.
2615
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002616- Issue #3476: binary buffered reading through the new "io" library is now
2617 thread-safe.
2618
Brett Cannonbf3157b2008-08-14 05:00:03 +00002619- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2620 since mimetools itself is deprecated. Because modules are cached, all
2621 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2622
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002623- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002625- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2626 menu entries were not deleted.
2627
Brett Cannon83e81842008-08-09 23:30:55 +00002628- Copied the implementation of reduce() to _functools.reduce() to have a
2629 version that did not raise a DeprecationWarning under -3.
2630
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002631- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2632 a MemoryError rather than silently stop the iteration.
2633
Guido van Rossum59ce9012008-08-09 14:55:34 +00002634- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2635 to _sre.compile() will now be rejected. This should not affect anybody
2636 since the re.compile() function never generates invalid re-bytecode.
2637
Skip Montanaroa032bf42008-08-08 22:52:51 +00002638- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2639 upon first access it can be automatically initialized from the csv file if
2640 it wasn't initialized during instantiation.
2641
Brett Cannon3aa2a492008-08-06 22:28:09 +00002642- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2643 the reload() built-in has been removed.
2644
Brett Cannon7e30b672008-08-04 21:52:25 +00002645- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002646 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2654 raised an AttributeError.
2655
Benjamin Peterson01a24322008-07-28 23:35:27 +00002656- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002657 asking for a specific length. This problem only affected files opened
2658 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002659
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002660- Issue #3449: Update decimal module to use most recent specification
2661 (v. 1.68) and tests (v. 2.58) from IBM.

2682
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002683- Issue #3394: zipfile.writestr sets external attributes when passed a
2684 file name rather than a ZipInfo instance, so files are extracted with
2685 mode 0600 rather than 000 under Unix.
2686
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002687- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2688 argument in python 2.5, this broke code that subclassed Popen to include its
2689 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2697-------------
2698
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002699- Issue #2235: the C API function PyObject_HashNotImplemented and its
2700 interaction with the tp_hash slot (added in 2.6b2) are now documented
2701
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002702- Issue #643841: The language reference now provides more detailed
2703 coverage of the lookup process for special methods. The disclaimers
2704 regarding lack of coverage of new-style classes have also been
2705 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002708What's New in Python 2.6 beta 2?
2709================================
2710
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002711*Release date: 17-Jul-2008*
2712
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002713Core and Builtins
2714-----------------
2715
Georg Brandl3e483f62008-07-16 22:57:41 +00002716- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2717 its methods now allow for items objects that can be converted to
2718 an integer using operator.index().
2719
Mark Dickinson64b7e502008-07-16 09:40:03 +00002720- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2721 produced a ValueError instead of giving the correct float.
2722
Eric Smitha5fa5a22008-07-16 00:11:49 +00002723- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2724 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2725
Mark Dickinson7103aa42008-07-15 19:08:33 +00002726- Issue #3008: the float type has a new instance method 'float.hex'
2727 and a new class method 'float.fromhex' to convert floating-point
2728 numbers to and from hexadecimal strings, respectively.
2729
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002730- Issue #2235: __hash__ is once again inherited by default. To allow
2731 collections.Hashable to remain meaningful in the presence of the
2732 default hash implementation (object.__hash__), it is now possible
2733 to explicit block inheritance of hash by setting __hash__=None at
2734 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2735 level.
2736
Nick Coghlanb028f502008-07-13 14:52:36 +00002737- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2738 the parent module cannot be found while performing an absolute import.
2739 This means that an incorrectly defined __package__ attribute will
2740 now only prevent relative imports in that module rather than causing
2741 all imports from that module to fail.
2742
Nick Coghlan14ff9942008-07-08 14:21:42 +00002743- Issue #2517: Allow unicode messages in Exceptions again by correctly
2744 bypassing the instance dictionary when looking up __unicode__ on
2745 new-style classes.
2746
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002747- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2748 set to a custom object whose write() method happens to install
2749 another file in sys.stdout.
2750
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002751- Issue #3088: Corrected a race condition in classes derived from
2752 threading.local: the first member set by a thread could be saved in
2753 another thread's dictionary.
2754
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002755- Issue #3004: Minor change to slice.indices(): the start and stop
2756 arguments are now treated identically, making the behaviour easier
2757 to describe and understand. For example, slice(None, -10,
2758 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2759 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2760 10, -1).
2761
Georg Brandl278fc502008-07-19 12:46:12 +00002762- Issue #3219: Calling a function with repeated keyword arguments,
2763 f(a=2, a=23), would not cause a syntax error. This was a regression
2764 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002765
Georg Brandl278fc502008-07-19 12:46:12 +00002766- Issue #2862: Make int and float freelist management consistent with
2767 other freelists. Changes their CompactFreeList apis into
2768 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002769

2771-------
2772
Thomas Heller57adf222008-08-14 19:10:48 +00002773- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2774 api functions without holding the GIL, which could lead to a fatal
2775 error when they failed.
2776
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002777- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002785- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2786 ForkingPickler.register() to resolve conflict with ctypes.
2787
Vinay Sajip51e65192008-07-18 09:01:10 +00002788- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002789
Thomas Heller880f5292008-07-15 19:39:38 +00002790- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2791 a valid dlerror() message.
2792
Thomas Heller2bad6572008-07-15 17:19:50 +00002793- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2794 incomplete structure was created.
2795
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002796- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00002798- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2799
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002800- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002801
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002802- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2803 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002804 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002805 content-length. The problem had been corrected in the 2.4 branch, but never
2806 merged into trunk.
2807
Georg Brandle78fbcc2008-07-05 10:13:36 +00002808- Issue #2663: add filtering capability to shutil.copytree().

2814- Issue #1746: Correct handling of zipfile archive comments (previously
2815 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002816 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002817
Vinay Sajip51e65192008-07-18 09:01:10 +00002818- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002819 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002820
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002821- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2822 handling is now the same as that of other special attributes like __name__).
2823
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002824- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2825 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00003214 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003215
3216 This is controlled by the configure argument ``--with-universal-archs``:
3217
3218 - ``--with-universal-archs=all``: install 4-way universal
3219
3220 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3221
3222 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3223
3224 This option should be used in combination with ``--enable-universalsdk=``.
3225
3226 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 +00003276- Issue #1631171: Re-implement the 'warnings' module in C (the
3277 original Python code has been kept as backup). This will allow for
3278 using the 'warning's machinery in such places as the parser where
3279 use of pure Python code is not possible. Both the ``showarning()``
3280 and ``formatwarning()`` gain an optional 'line' argument which is
3281 not called by default for backwards-compatibility reasons. Setting
3282 ``warnings.showwarning()`` to an implementation that lacks support
3283 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003346- Issue #2550: The approach used by client/server code for obtaining
3347 ports to listen on in network-oriented tests has been refined in an
3348 effort to facilitate running multiple instances of the entire
3349 regression test suite in parallel without issue.
3350 test_support.bind_port() has been fixed such that it will always
3351 return a unique port -- which wasn't always the case with the
3352 previous implementation, especially if socket options had been set
3353 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3354 new implementation of bind_port() will actually raise an exception
3355 if it is passed an AF_INET/SOCK_STREAM socket with either the
3356 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3357 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3358 the socket it's been passed. This currently only applies to
3359 Windows. This option prevents any other sockets from binding to the
3360 host/port we've bound to, thus removing the possibility of the
3361 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3362 when a second SOCK_STREAM socket binds and accepts to a host/port
3363 that's already been bound by another socket. The optional preferred
3364 port parameter to bind_port() has been removed. Under no
3365 circumstances should tests be hard coding ports!
3366
3367 test_support.find_unused_port() has also been introduced, which will
3368 pass a temporary socket object to bind_port() in order to obtain an
3369 unused port. The temporary socket object is then closed and
3370 deleted, and the port is returned. This method should only be used
3371 for obtaining an unused port in order to pass to an external program
3372 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3373 a parameter to a server-oriented class that doesn't give you direct
3374 access to the underlying socket used.
3375
3376 Finally, test_support.HOST has been introduced, which should be used
3377 for the host argument of any relevant socket calls (i.e. bind and
3378 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003379
3380 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3383 test_asynchat and test_socket_ssl.
3384
Georg Brandl3ee81df2008-05-17 18:14:43 +00003385 It is now possible for multiple instances of the regression test

3653-----------------
3654
Fred Drakea8ee94b2008-03-01 02:45:07 +00003655- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003656 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003657
Georg Brandlad61bc82008-02-23 15:11:18 +00003658- Issue #2067: file.__exit__() now calls subclasses' close() method.
3659
3660- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003661
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003662- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003663 issue 215555 for a discussion.
3664
Eric Smitha73fbe72008-02-23 03:09:44 +00003665- Added the future_builtins module, which contains hex() and oct().
3666 These are the PEP 3127 version of these functions, designed to be
3667 compatible with the hex() and oct() builtins from Python 3.0. They
3668 differ slightly in their output formats from the existing, unchanged
3669 Python 2.6 builtins. The expected usage of the future_builtins
3670 module is:
3671 from future_builtins import hex, oct
3672
Eric Smith7ef40bf2008-02-20 23:34:22 +00003673- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3674 exponents for exponents with absolute value < 100. Follows C99
3675 standard. This is a change on Windows, which would use 3 digits.
3676 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3677 so that any alterations it does to the resulting string will be
3678 available in stringlib/formatter.h (for float.__format__).
3679
Eric Smith5a3c1352008-02-19 13:21:56 +00003680- Implemented PEP 3101, Advanced String Formatting. This adds a new
3681 builtin format(); a format() method for str and unicode; a
3682 __format__() method to object, str, unicode, int, long, float, and
3683 datetime; the class string.Formatter; and the C API
3684 PyObject_Format().
3685
Georg Brandl3ee81df2008-05-17 18:14:43 +00003686- Fixed several potential crashes, all caused by specially crafted
3687 __del__ methods exploiting objects in temporarily inconsistent
3688 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003689
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003690- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003691 prevent a possible crash: an Abstract Base Class would try to access
3692 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003693
Georg Brandl3ee81df2008-05-17 18:14:43 +00003694- Fixed repr() and str() of complex numbers with infinity or nan as
3695 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003696
Georg Brandl3ee81df2008-05-17 18:14:43 +00003697- Clear all free lists during a gc.collect() of the highest generation
3698 in order to allow pymalloc to free more arenas. Python may give back
3699 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003700
Georg Brandl3ee81df2008-05-17 18:14:43 +00003701- Issue #2045: Fix an infinite recursion triggered when printing a
3702 subclass of collections.defaultdict, if its default_factory is set
3703 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003704
Christian Heimesf75dbef2008-02-08 00:11:31 +00003705- Fixed a minor memory leak in dictobject.c. The content of the free
3706 list was not freed on interpreter shutdown.
3707
Georg Brandl3ee81df2008-05-17 18:14:43 +00003708- Limit free list of method and builtin function objects to 256
3709 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003710
Georg Brandl3ee81df2008-05-17 18:14:43 +00003711- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3712 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003713 to compact the internal free lists of pre-allocted ints and floats.
3714
Georg Brandl3ee81df2008-05-17 18:14:43 +00003715- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3716 calls. Python expected the return type int but the fork familie
3717 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003718
Georg Brandl3ee81df2008-05-17 18:14:43 +00003719- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3720 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003721
Georg Brandl3ee81df2008-05-17 18:14:43 +00003722- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3723 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003724
Georg Brandl3ee81df2008-05-17 18:14:43 +00003725- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3726 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003727
Georg Brandl3ee81df2008-05-17 18:14:43 +00003728- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3729 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003730
Georg Brandl3ee81df2008-05-17 18:14:43 +00003731- Patch #1473257: generator objects gain a gi_code attribute. This is
3732 the same object as the func_code attribute of the function that
3733 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003734
Georg Brandl3ee81df2008-05-17 18:14:43 +00003735- Issue #1920: "while 0" statements were completely removed by the
3736 compiler, even in the presence of an "else" clause, which is
3737 supposed to be run when the condition is false. Now the compiler
3738 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003739
Guido van Rossumeead05f2008-01-24 18:21:02 +00003740- A few crashers fixed: weakref_in_del.py (issue #1377858);
3741 loosing_dict_ref.py (issue #1303614, test67.py);
3742 borrowed_ref_[34].py (not in tracker).
3743
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003744- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003745 suppressed while an extension is loaded by calling SetErrorMode in
3746 dynload_win.c. The error is still reported properly.
3747
Georg Brandl3ee81df2008-05-17 18:14:43 +00003748- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003749 several extension methods and modules do not work without unicode
3750 support.
3751
Georg Brandl26543b12008-01-21 18:36:51 +00003752- Issue #1882: when compiling code from a string, encoding cookies in the
3753 second line of code were not always recognized correctly.
3754
Georg Brandl14404b62008-01-19 19:27:05 +00003755- Issue #1679: "0x" was taken as a valid integer literal.
3756
Georg Brandl6caad7d2008-01-26 14:19:22 +00003757- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003758 added.
3759
Christian Heimesc94e2b52008-01-14 04:13:37 +00003760- sys.float_info / PyFloat_GetInfo: The floating point information
3761 object was converted from a dict to a specialized structseq object.
3762
Georg Brandl3ee81df2008-05-17 18:14:43 +00003763- Patch #1816: Added sys.flags structseq. It exposes the status of
3764 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Objects/structseq.c: Implemented new structseq representation. The
3767 patch makes structseqs (e.g. the return value of os.stat) more
3768 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003769
Georg Brandl3ee81df2008-05-17 18:14:43 +00003770- Patch #1700288: added a type attribute cache that caches method
3771 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003772
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003773- Bug #1776: __import__() no longer accepts filenames on any platform.
3774 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003775
Georg Brandlaed6c662008-01-07 17:25:53 +00003776- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3777
Georg Brandl3ee81df2008-05-17 18:14:43 +00003778- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3779 envvar and sys.dont_write_bytecode attribute. All these can be set
3780 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003781
Georg Brandl3ee81df2008-05-17 18:14:43 +00003782- Improve some exception messages when Windows fails to load an
3783 extension module. Now we get for example '%1 is not a valid Win32
3784 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003785
Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003788- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3789 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003790
Christian Heimes0a8143f2007-12-18 23:22:54 +00003791- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003792 and INF. float("nan"), float("inf") and float("-inf") now work on
3793 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003794
Georg Brandl3ee81df2008-05-17 18:14:43 +00003795- Compiler now generates simpler and faster code for dictionary
3796 literals. The oparg for BUILD_MAP now indicates an estimated
3797 dictionary size. There is a new opcode, STORE_MAP, for adding
3798 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003799
Georg Brandl3ee81df2008-05-17 18:14:43 +00003800- Issue #1638: %zd configure test fails on Linux.

3813 __package__ attribute.
3814
Georg Brandl3ee81df2008-05-17 18:14:43 +00003815- Issue #1402: Fix a crash on exit, when another thread is still
3816 running, and if the deallocation of its frames somehow calls the
3817 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003818

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003822 attribute of an empty cell object.
3823
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824- Issue #1460: The utf-7 incremental decoder did not accept truncated
3825 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003826

3828 file can now be directly executed by passing their name to the
3829 interpreter. The directory/zipfile is automatically inserted as the
3830 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003831
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832- Issue #1265: Fix a problem with sys.settrace, if the tracing
3833 function uses a generator expression when at the same time the
3834 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003835
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003836- sets and frozensets now have an isdisjoint() method.
3837
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003838- optimize the performance of builtin.sum().
3839
Neal Norwitz44f326e2007-10-05 05:29:17 +00003840- Fix warnings found by the new version of the Coverity checker.
3841
Georg Brandl3ee81df2008-05-17 18:14:43 +00003842- The enumerate() builtin function is no longer bounded to sequences
3843 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3844 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003845
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846- Issue #1686386: Tuple's tp_repr did not take into account the
3847 possibility of having a self-referential tuple, which is possible
3848 from C code. Nor did object's tp_str consider that a type's tp_str
3849 could do something that could lead to an inifinite recursion.
3850 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3851 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003852
Georg Brandl3ee81df2008-05-17 18:14:43 +00003853- Issue #1164: It was possible to trigger deadlock when using the
3854 'print' statement to write to a file since the GIL was not released
3855 as needed. Now PyObject_Print() does the right thing along with
3856 various tp_print implementations of the built-in types and those in
3857 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003858
Georg Brandl3ee81df2008-05-17 18:14:43 +00003859- Issue #1147: Exceptions were directly allowing string exceptions in
3860 their throw() method even though string exceptions no longer
3861 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003862
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003866- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867 PyObject_Call() never calling back out to Python code to trigger
3868 recursion depth updates/checks. Required the creation of a static
3869 RuntimeError instance in case normalizing an exception put the
3870 recursion check value past its limit. Fixes crashers
3871 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003872
Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003886- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003887 __*__ attributes. (Some already existed, e.g., __doc__ and
3888 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003889
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003890- Add -3 option to the interpreter to warn about features that are
3891 deprecated and will be changed/removed in Python 3.0.
3892
Georg Brandl2134e752007-05-21 20:34:16 +00003893- Patch #1686487: you can now pass any mapping after '**' in function
3894 calls.
3895
Collin Winter62903052007-05-18 23:11:24 +00003896- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003897 "except E as target:". This is to provide forwards compatibility
3898 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003899
Brett Cannon229cee22007-05-05 01:34:02 +00003900- Deprecate BaseException.message as per PEP 352.
3901
Georg Brandl3ee81df2008-05-17 18:14:43 +00003902- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003903 inherited from a builtin base.
3904
Vinay Sajip8549ce32007-05-06 17:53:37 +00003905- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003906 setting a plain string, ie don't expand to single letter identifiers.
3907
Raymond Hettinger13936692007-04-11 18:40:58 +00003908- Request #1191699: Slices can now be pickled.

3918
Guido van Rossum143b5642007-03-23 04:58:42 +00003919- Bug #1683368: The object.__init__() and object.__new__() methods are
3920 now stricter in rejecting excess arguments. The only time when
3921 either allows excess arguments is when it is not overridden and the
3922 other one is. For backwards compatibility, when both are
3923 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003924 warning later). Also, type.__init__() insists on the same signature
3925 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003926
Georg Brandl3ee81df2008-05-17 18:14:43 +00003927- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3928 object to complex using its __complex__() method before falling back
3929 to the __float__() method. Therefore, the functions in the cmath
3930 module now can operate on objects that define a __complex__()
3931 method.

3948
Georg Brandl7b9c5552007-03-12 14:30:05 +00003949- Bug #1678647: write a newline after printing an exception in any
3950 case, even when converting the value to a string failed.
3951
Georg Brandl871f1bc2007-03-12 13:17:36 +00003952- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003953 its argument, if it exists. If not, it will work like before. This
3954 allows customizing the output of dir() in the presence of a
3955 __getattr__().

3958 self-recursive reload() calls (as reported by bug #742342).
3959

3964 parthensized forms. This means complex(repr(x)) now works instead of
3965 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003966
Georg Brandlaa2321b2007-03-07 00:40:28 +00003967- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003968 makes the filenames the warning module prints much more sensible
3969 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003970

Georg Brandl0fca97a2007-03-05 22:28:08 +00003982- Patch #1674228: when assigning a slice (old-style), check for the
3983 sq_ass_slice instead of the sq_slice slot.
3984
Georg Brandl3ee81df2008-05-17 18:14:43 +00003985- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004088 generator expressions (x for x, in ... ) works again. Fixing this
4089 problem required changing the .pyc magic number. This means that
4090 .pyc files generated before 2.5c2 will be regenerated.

4612 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004897- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4898 with RFC 3207 and forgets any knowledge obtained from the server not
4899 obtained from the TLS negotiation itself. Patch contributed by Bill
4900 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004901
Georg Brandl3ee81df2008-05-17 18:14:43 +00004902- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004903 that the SMTP.starttls() caller no longer needs to call ehlo()
4904 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004905 does not claim to support starttls. Adds the
4906 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4987 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4988 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005005 time so that opening a database previously created with the DB_DUP
5006 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5007 opens. Specifically: dictionary assignment to a DB object will
5008 replace all values for a given key when the database allows
5009 duplicate values. DB users should use DB.put(k, v) when they want
5010 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005011

5017 characters with ASCII value less than 32. Also, it correctly quotes
5018 dots only if they occur on a single line, as opposed to the previous
5019 behavior of quoting dots if they are the second character of any
5020 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005021

Georg Brandl3ee81df2008-05-17 18:14:43 +00005426- Removed the macfs module. It had been deprecated since Python 2.5.
5427 This lead to the deprecation of macostools.touched() as it relied
5428 solely on macfs and was a no-op under OS X.
