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

501
Mark Dickinsonb678de82009-11-19 18:41:49 +0000502- Issue #7117: repr(x) for a float x returns a result based on the
503 shortest decimal string that's guaranteed to round back to x under
504 correct rounding (with round-half-to-even rounding mode).
505 Previously it gave a string based on rounding x to 17 decimal digits.
506 repr(x) for a complex number behaves similarly. On platforms where
507 the correctly-rounded strtod and dtoa code is not supported (see below),
508 repr is unchanged.
509
510- Issue #7117: On almost all platforms: float-to-string and
511 string-to-float conversions within Python are now correctly rounded.
512 Places these conversions occur include: str for floats and complex
513 numbers; the float and complex constructors; old-style and new-style
514 numeric formatting; serialization and deserialization of floats and
515 complex numbers using marshal, pickle and json; parsing of float and
516 imaginary literals in Python code; Decimal-to-float conversion.
517
518 The conversions use a Python-adapted version of David Gay's
519 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
520 functions. This code is supported on Windows, and on Unix-like
521 platforms using gcc, icc or suncc as the C compiler. There may be a
522 small number of platforms on which correct operation of this code
523 cannot be guaranteed, so the code is not used: notably, this applies
524 to platforms where the C double format is not IEEE 754 binary64, and
525 to platforms on x86 hardware where the x87 FPU is set to 64-bit
526 precision and Python's configure script is unable to determine how
527 to change the FPU precision. On these platforms conversions use the
528 platform strtod and dtoa, as before.
529
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000530- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000531 now uses the correctly-rounded string <-> float conversions
532 described above (when available), and so produces correctly rounded
533 results that will display nicely under the float repr. There are
534 two related small changes: (1) round now accepts any class with an
535 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000536 floats for the second argument), and (2) an excessively large second
537 integer argument (e.g., round(1.234, 10**100)) no longer raises an
538 exception.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000666- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
667 statement and correctly lookup the __enter__ and __exit__ special methods.
668
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000669- Issue #5829: complex("1e500") no longer raises OverflowError. This
670 makes it consistent with float("1e500") and interpretation of real
671 and imaginary literals.
672
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000673- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

679
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000680- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
681 (1) inf and nan strings with trailing whitespace were incorrectly
682 rejected; (2) parsing of strings representing infinities and nans
683 was locale aware; and (3) the interpretation of fromhex('-nan')
684 didn't match that of float('-nan').
685
Eric Smitha985a3a2009-05-05 18:26:08 +0000686- Issue #5920: For float.__format__, change the behavior with the
687 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
688 to be like 'g' but with at least one decimal point and with a
689 default precision of 12. Previously, the behavior the same but with
690 a default precision of 6. This more closely matches str(), and
691 reduces surprises when adding alignment flags to the empty
692 presentation type. This also affects the new complex.__format__ in
693 the same way.
694
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000695- Issue #5890: in subclasses of 'property' the __doc__ attribute was
696 shadowed by classtype's, even if it was None. property now
697 inserts the __doc__ into the subclass instance __dict__.
698

723 floats, ints, and longs.
724
725- Issue #5515: 'n' formatting for ints, longs, and floats handles
726 leading zero formatting poorly.
727

735 some builtin types.
736
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000737- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000738 was giving 5e15+2; round(-0.0) was losing the sign of the zero.

756
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000757- Issue #4688: Add a heuristic so that tuples and dicts containing only
758 untrackable objects are not tracked by the garbage collector. This can
759 reduce the size of collections and therefore the garbage collection overhead
760 on long-running programs, depending on their particular use of datatypes.
761
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000762- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

764 are now between 50% and 150% faster.
765
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000766- Issue #4258: Make it possible to use base 2**30 instead of base
767 2**15 for the internal representation of integers, for performance
768 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
769 --enable-big-digits option to configure, which overrides the
770 default. Add sys.long_info structseq to provide information about
771 the internal format.
772
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000773- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
774 result traceback.__members__ no longer exists.)
775
Mark Dickinson6b265f12009-03-18 16:07:26 +0000776- Issue #4474: PyUnicode_FromWideChar now converts characters outside
777 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

782
Brett Cannon6c4cff02009-03-11 04:51:06 +0000783- Issue #3652: Make the 'line' argument for warnings.showwarning() a
784 requirement. Means the DeprecationWarning from Python 2.6 can go away.
785
Eric Smithe9fb6862009-02-20 14:02:36 +0000786- Issue #5247: Improve error message when unknown format codes are
787 used when using str.format() with str, unicode, long, int, and
788 float arguments.
789
Raymond Hettinger08259e82009-02-18 23:10:19 +0000790- Running Python with the -3 option now also warns about classic division
791 for ints and longs.
792
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000793- Issue #5260: Long integers now consume less memory: average
794 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
795 on a 64-bit system.
796
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000797- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
798 rotating the object pointer by 4 bits to the right.
799
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000800- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
801 it now forces its argument to double before testing for infinity.

804
Georg Brandl29c6a282009-04-05 20:23:13 +0000805- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000806 were suppressing all exceptions. These include list(), filter(), map(),
807 zip(), and bytearray().
808
Benjamin Peterson596d3062009-01-19 15:42:23 +0000809- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
810 functions.
811
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000812- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

837 an existing .py counterpart, override the co_filename attributes of all
838 code objects if the original filename is obsolete (which can happen if the
839 file has been renamed, moved, or if it is accessed through different paths).

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000921- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
922 returned a path longer than MAX_PATH. (But It's doubtful this code path is
923 really executed because I cannot move to such directory on win2k)
924
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000925- Issue #4069: When set.remove(element) is used with a set element, the element
926 is temporarily replaced with an equivalent frozenset. But the eventual

928 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000948- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
949 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
950 step. This avoids problems with counting UTF-8 bytes that ignores the effect
951 of using the replace error handler in PyUnicode_DecodeUTF8().
952
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000953- Issue #3739: The unicode-internal encoder now reports the number of characters

955
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000956- Issue #2422: When compiled with the ``--with-valgrind`` option, the
957 pymalloc allocator will be automatically disabled when running under
958 Valgrind. This gives improved memory leak detection when running
959 under Valgrind, while taking advantage of pymalloc at other times.

2274 true singleton object.
2275
Brett Cannonb2d61bd2008-09-29 03:41:21 +00002276- Issue #3895: It was possible to crash the interpreter when an external timer

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00002320 AttributeError instead of RuntimeError, depending in which C API call

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002339- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2340
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002341- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2342 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2343 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2344 ``printf`` function, whereas PyString_FromFormat has an independent
2345 implementation and uses "%zd" on all platforms for size_t values.
2346 This makes a difference on win64, where ``printf`` needs "%Id" to display
2347 64bit values.
2348
Benjamin Peterson97179b02008-09-09 20:55:01 +00002349- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2353 object; previously an int would be returned for small values. the __long__
2354 method is allowed to return either an int or a long, but the behaviour of
2355 float objects should not change to respect backward compatibility.
2356
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002357- Issue #3751: str.rpartition would perform a left-partition when called with
2358 a unicode argument.
2359
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002360- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002363 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002364 was correctly parsed but parsing of subsequent arguments failed.
2365
Vinay Sajip35e3b032008-09-01 14:33:59 +00002366- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002367 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2368 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2369 when given a tuple of classes as second argument, were looking up
2370 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2371 type object.
2372
Neal Norwitz18aa3882008-08-24 05:04:52 +00002373- Fix crashes on memory allocation failure found with failmalloc.
2374
2375- Fix memory leaks found with valgrind and update suppressions file.
2376
2377- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2378
2379- Fix problem using wrong name in decimal module reported by pychecker.

2388 library targets in the Makefile.
2389
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002390- Issue #1204: The configure script now tests for additional libraries
2391 that may be required when linking against readline. This fixes issues
2392 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00002415- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002416 return a list or None rather than a custom object.
2417
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002418- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2442 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2443 for catch_warnings() also led to an improvement in the raising of a
2444 DeprecationWarning related to warnings.warn_explicit().

2516-----------------
2517
Guido van Rossumf8402962008-08-20 15:01:50 +00002518- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2519 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2520 extensions do not automatically benefit from the class attribute
2521 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2522 to their tp_flags field if they care. This is a backwards
2523 compatibility feature; in 3.0, all types will use the cache by
2524 default.
2525
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002526- Keyword arguments can now follow starred arguments. (``f(a, *args,
2527 keyword=23)`` is now valid syntax.)
2528
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002529- ctypes function pointers that are COM methods have a boolean True
2530 value again.
2531
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002532- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2533 by denying s# to parse objects that have a releasebuffer procedure,
2534 and introducing s*.
2535
Georg Brandl1e13ea92008-08-11 09:07:59 +00002536- Issue #3537: Fix an assertion failure when an empty but presized dict
2537 object was stored in the freelist.
2538
Mark Dickinsonb6467572008-08-04 21:30:09 +00002539- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2540 ValueError consistently across platforms.
2541
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002542- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2543 (64bit Unix, for example), unichr() would truncate its argument and return
2544 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2545
Neal Norwitze7d8be82008-07-31 17:17:14 +00002546- Apply security patches from Apple.
2547
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002548- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2549 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2550
Antoine Pitrou92f82162008-07-25 22:22:08 +00002551- Issue #1819: function calls with several named parameters are now on

Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002554- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2555 the python debugger steps into a class statement: the free variables (local
2556 variables defined in an outer scope) would be deleted from the outer scope.
2557
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002558- Issue #2620: Overflow checking when allocating or reallocating memory
2559 was not always being done properly in some python types and extension
2560 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2561 all been updated to perform better checks and places in the code that
2562 would previously leak memory on the error path when such an allocation
2563 failed have been fixed.

2569
Benjamin Petersone977ad42008-08-20 01:42:01 +00002570- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2571 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2572
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002573- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2574 version reported by these tools does not necessarily follow the python
2575 version numbering scheme, so the module is less strict when parsing it.
2576
Nick Coghlanf70385a2008-08-18 12:42:46 +00002577- Issue #2235: Added Py3k warnings for types which will become unhashable
2578 under the stricter __hash__ inheritance rules in 3.0. Several types
2579 which did not meet the rules for hash invariants and were already
2580 unhashable in 3.0 have now been explicitly flagged as unhashable in
2581 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2582 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2583
Brett Cannon88f801d2008-08-18 00:46:22 +00002584- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2606 after a 302 response in the case of not going through a proxy.
2607
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002608- Issue #2676: in the email package, content-type parsing was hanging on

2610 regular expression.
2611
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002612- Issue #3476: binary buffered reading through the new "io" library is now
2613 thread-safe.
2614
Brett Cannonbf3157b2008-08-14 05:00:03 +00002615- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2616 since mimetools itself is deprecated. Because modules are cached, all
2617 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2618
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002619- Issue #3134: shutil referenced undefined WindowsError symbol.

2622 menu entries were not deleted.
2623
Brett Cannon83e81842008-08-09 23:30:55 +00002624- Copied the implementation of reduce() to _functools.reduce() to have a
2625 version that did not raise a DeprecationWarning under -3.
2626
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002627- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2628 a MemoryError rather than silently stop the iteration.
2629
Guido van Rossum59ce9012008-08-09 14:55:34 +00002630- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2631 to _sre.compile() will now be rejected. This should not affect anybody
2632 since the re.compile() function never generates invalid re-bytecode.
2633
Skip Montanaroa032bf42008-08-08 22:52:51 +00002634- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2635 upon first access it can be automatically initialized from the csv file if
2636 it wasn't initialized during instantiation.
2637
Brett Cannon3aa2a492008-08-06 22:28:09 +00002638- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2639 the reload() built-in has been removed.
2640
Brett Cannon7e30b672008-08-04 21:52:25 +00002641- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002642 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2650 raised an AttributeError.
2651
Benjamin Peterson01a24322008-07-28 23:35:27 +00002652- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002653 asking for a specific length. This problem only affected files opened
2654 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002655

2678
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002679- Issue #3394: zipfile.writestr sets external attributes when passed a
2680 file name rather than a ZipInfo instance, so files are extracted with
2681 mode 0600 rather than 000 under Unix.
2682
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002683- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2684 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002695- Issue #2235: the C API function PyObject_HashNotImplemented and its
2696 interaction with the tp_hash slot (added in 2.6b2) are now documented
2697
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002698- Issue #643841: The language reference now provides more detailed
2699 coverage of the lookup process for special methods. The disclaimers
2700 regarding lack of coverage of new-style classes have also been
2701 removed, since the coverage is now fairly reasonable.

2705================================
2706
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002707*Release date: 17-Jul-2008*
2708
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002709Core and Builtins
2710-----------------
2711
Georg Brandl3e483f62008-07-16 22:57:41 +00002712- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2713 its methods now allow for items objects that can be converted to
2714 an integer using operator.index().
2715
Mark Dickinson64b7e502008-07-16 09:40:03 +00002716- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2717 produced a ValueError instead of giving the correct float.
2718
Eric Smitha5fa5a22008-07-16 00:11:49 +00002719- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2720 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2721
Mark Dickinson7103aa42008-07-15 19:08:33 +00002722- Issue #3008: the float type has a new instance method 'float.hex'
2723 and a new class method 'float.fromhex' to convert floating-point
2724 numbers to and from hexadecimal strings, respectively.
2725
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002726- Issue #2235: __hash__ is once again inherited by default. To allow
2727 collections.Hashable to remain meaningful in the presence of the
2728 default hash implementation (object.__hash__), it is now possible
2729 to explicit block inheritance of hash by setting __hash__=None at
2730 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2731 level.
2732
Nick Coghlanb028f502008-07-13 14:52:36 +00002733- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2734 the parent module cannot be found while performing an absolute import.
2735 This means that an incorrectly defined __package__ attribute will
2736 now only prevent relative imports in that module rather than causing
2737 all imports from that module to fail.
2738
Nick Coghlan14ff9942008-07-08 14:21:42 +00002739- Issue #2517: Allow unicode messages in Exceptions again by correctly
2740 bypassing the instance dictionary when looking up __unicode__ on
2741 new-style classes.
2742
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002743- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2744 set to a custom object whose write() method happens to install
2745 another file in sys.stdout.
2746
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002747- Issue #3088: Corrected a race condition in classes derived from
2748 threading.local: the first member set by a thread could be saved in
2749 another thread's dictionary.
2750
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002751- Issue #3004: Minor change to slice.indices(): the start and stop
2752 arguments are now treated identically, making the behaviour easier
2753 to describe and understand. For example, slice(None, -10,
2754 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2755 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2756 10, -1).
2757
Georg Brandl278fc502008-07-19 12:46:12 +00002758- Issue #3219: Calling a function with repeated keyword arguments,
2759 f(a=2, a=23), would not cause a syntax error. This was a regression
2760 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002761
Georg Brandl278fc502008-07-19 12:46:12 +00002762- Issue #2862: Make int and float freelist management consistent with
2763 other freelists. Changes their CompactFreeList apis into
2764 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002765

2767-------
2768
Thomas Heller57adf222008-08-14 19:10:48 +00002769- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2770 api functions without holding the GIL, which could lead to a fatal
2771 error when they failed.
2772
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002773- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002781- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2782 ForkingPickler.register() to resolve conflict with ctypes.
2783
Vinay Sajip51e65192008-07-18 09:01:10 +00002784- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002785
Thomas Heller880f5292008-07-15 19:39:38 +00002786- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2787 a valid dlerror() message.
2788
Thomas Heller2bad6572008-07-15 17:19:50 +00002789- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2790 incomplete structure was created.
2791

2795
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002796- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002797
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002798- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2799 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002800 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002801 content-length. The problem had been corrected in the 2.4 branch, but never
2802 merged into trunk.
2803
Georg Brandle78fbcc2008-07-05 10:13:36 +00002804- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002815 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002816
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002817- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2818 handling is now the same as that of other special attributes like __name__).
2819
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002820- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2821 removal in Python 3.0 in favor of urllib2.urlopen().

3209 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003210 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003211
3212 This is controlled by the configure argument ``--with-universal-archs``:
3213
3214 - ``--with-universal-archs=all``: install 4-way universal
3215
3216 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3217
3218 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3219
3220 This option should be used in combination with ``--enable-universalsdk=``.
3221
3222 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 +00003272- Issue #1631171: Re-implement the 'warnings' module in C (the
3273 original Python code has been kept as backup). This will allow for
3274 using the 'warning's machinery in such places as the parser where
3275 use of pure Python code is not possible. Both the ``showarning()``
3276 and ``formatwarning()`` gain an optional 'line' argument which is
3277 not called by default for backwards-compatibility reasons. Setting
3278 ``warnings.showwarning()`` to an implementation that lacks support
3279 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003342- Issue #2550: The approach used by client/server code for obtaining
3343 ports to listen on in network-oriented tests has been refined in an
3344 effort to facilitate running multiple instances of the entire
3345 regression test suite in parallel without issue.
3346 test_support.bind_port() has been fixed such that it will always
3347 return a unique port -- which wasn't always the case with the
3348 previous implementation, especially if socket options had been set
3349 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3350 new implementation of bind_port() will actually raise an exception
3351 if it is passed an AF_INET/SOCK_STREAM socket with either the
3352 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3353 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3354 the socket it's been passed. This currently only applies to
3355 Windows. This option prevents any other sockets from binding to the
3356 host/port we've bound to, thus removing the possibility of the
3357 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3358 when a second SOCK_STREAM socket binds and accepts to a host/port
3359 that's already been bound by another socket. The optional preferred
3360 port parameter to bind_port() has been removed. Under no
3361 circumstances should tests be hard coding ports!
3362
3363 test_support.find_unused_port() has also been introduced, which will
3364 pass a temporary socket object to bind_port() in order to obtain an
3365 unused port. The temporary socket object is then closed and
3366 deleted, and the port is returned. This method should only be used
3367 for obtaining an unused port in order to pass to an external program
3368 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3369 a parameter to a server-oriented class that doesn't give you direct
3370 access to the underlying socket used.
3371
3372 Finally, test_support.HOST has been introduced, which should be used
3373 for the host argument of any relevant socket calls (i.e. bind and
3374 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003375
3376 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003377 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003378 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3379 test_asynchat and test_socket_ssl.
3380
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381 It is now possible for multiple instances of the regression test
3382 suite to run in parallel without issue.

Fred Drakea8ee94b2008-03-01 02:45:07 +00003651- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003652 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003653
Georg Brandlad61bc82008-02-23 15:11:18 +00003654- Issue #2067: file.__exit__() now calls subclasses' close() method.
3655
3656- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003657
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003658- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003659 issue 215555 for a discussion.
3660
Eric Smitha73fbe72008-02-23 03:09:44 +00003661- Added the future_builtins module, which contains hex() and oct().
3662 These are the PEP 3127 version of these functions, designed to be
3663 compatible with the hex() and oct() builtins from Python 3.0. They
3664 differ slightly in their output formats from the existing, unchanged
3665 Python 2.6 builtins. The expected usage of the future_builtins
3666 module is:
3667 from future_builtins import hex, oct
3668
Eric Smith7ef40bf2008-02-20 23:34:22 +00003669- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3670 exponents for exponents with absolute value < 100. Follows C99
3671 standard. This is a change on Windows, which would use 3 digits.
3672 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3673 so that any alterations it does to the resulting string will be
3674 available in stringlib/formatter.h (for float.__format__).
3675
Eric Smith5a3c1352008-02-19 13:21:56 +00003676- Implemented PEP 3101, Advanced String Formatting. This adds a new
3677 builtin format(); a format() method for str and unicode; a
3678 __format__() method to object, str, unicode, int, long, float, and
3679 datetime; the class string.Formatter; and the C API
3680 PyObject_Format().
3681
Georg Brandl3ee81df2008-05-17 18:14:43 +00003682- Fixed several potential crashes, all caused by specially crafted
3683 __del__ methods exploiting objects in temporarily inconsistent
3684 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003685
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003686- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003687 prevent a possible crash: an Abstract Base Class would try to access
3688 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003689
Georg Brandl3ee81df2008-05-17 18:14:43 +00003690- Fixed repr() and str() of complex numbers with infinity or nan as
3691 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003692
Georg Brandl3ee81df2008-05-17 18:14:43 +00003693- Clear all free lists during a gc.collect() of the highest generation
3694 in order to allow pymalloc to free more arenas. Python may give back
3695 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003696
Georg Brandl3ee81df2008-05-17 18:14:43 +00003697- Issue #2045: Fix an infinite recursion triggered when printing a
3698 subclass of collections.defaultdict, if its default_factory is set
3699 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003700
Christian Heimesf75dbef2008-02-08 00:11:31 +00003701- Fixed a minor memory leak in dictobject.c. The content of the free
3702 list was not freed on interpreter shutdown.
3703
Georg Brandl3ee81df2008-05-17 18:14:43 +00003704- Limit free list of method and builtin function objects to 256
3705 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003706
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3708 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003709 to compact the internal free lists of pre-allocted ints and floats.
3710
Georg Brandl3ee81df2008-05-17 18:14:43 +00003711- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3712 calls. Python expected the return type int but the fork familie
3713 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003714
Georg Brandl3ee81df2008-05-17 18:14:43 +00003715- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3716 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003717
Georg Brandl3ee81df2008-05-17 18:14:43 +00003718- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3719 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003720
Georg Brandl3ee81df2008-05-17 18:14:43 +00003721- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3722 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003723
Georg Brandl3ee81df2008-05-17 18:14:43 +00003724- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3725 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003726
Georg Brandl3ee81df2008-05-17 18:14:43 +00003727- Patch #1473257: generator objects gain a gi_code attribute. This is
3728 the same object as the func_code attribute of the function that
3729 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003730
Georg Brandl3ee81df2008-05-17 18:14:43 +00003731- Issue #1920: "while 0" statements were completely removed by the
3732 compiler, even in the presence of an "else" clause, which is
3733 supposed to be run when the condition is false. Now the compiler
3734 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003735
Guido van Rossumeead05f2008-01-24 18:21:02 +00003736- A few crashers fixed: weakref_in_del.py (issue #1377858);
3737 loosing_dict_ref.py (issue #1303614, test67.py);
3738 borrowed_ref_[34].py (not in tracker).
3739
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003740- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003741 suppressed while an extension is loaded by calling SetErrorMode in
3742 dynload_win.c. The error is still reported properly.
3743
Georg Brandl3ee81df2008-05-17 18:14:43 +00003744- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003745 several extension methods and modules do not work without unicode
3746 support.
3747
Georg Brandl26543b12008-01-21 18:36:51 +00003748- Issue #1882: when compiling code from a string, encoding cookies in the
3749 second line of code were not always recognized correctly.
3750
Georg Brandl14404b62008-01-19 19:27:05 +00003751- Issue #1679: "0x" was taken as a valid integer literal.
3752
Georg Brandl6caad7d2008-01-26 14:19:22 +00003753- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003754 added.
3755
Christian Heimesc94e2b52008-01-14 04:13:37 +00003756- sys.float_info / PyFloat_GetInfo: The floating point information
3757 object was converted from a dict to a specialized structseq object.
3758
Georg Brandl3ee81df2008-05-17 18:14:43 +00003759- Patch #1816: Added sys.flags structseq. It exposes the status of
3760 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003761
Georg Brandl3ee81df2008-05-17 18:14:43 +00003762- Objects/structseq.c: Implemented new structseq representation. The
3763 patch makes structseqs (e.g. the return value of os.stat) more
3764 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Patch #1700288: added a type attribute cache that caches method
3767 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003768
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003769- Bug #1776: __import__() no longer accepts filenames on any platform.
3770 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003771

3773
Georg Brandl3ee81df2008-05-17 18:14:43 +00003774- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3775 envvar and sys.dont_write_bytecode attribute. All these can be set
3776 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003777
Georg Brandl3ee81df2008-05-17 18:14:43 +00003778- Improve some exception messages when Windows fails to load an
3779 extension module. Now we get for example '%1 is not a valid Win32
3780 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003781
Georg Brandl3ee81df2008-05-17 18:14:43 +00003782- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003784- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3785 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003786
Christian Heimes0a8143f2007-12-18 23:22:54 +00003787- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003788 and INF. float("nan"), float("inf") and float("-inf") now work on
3789 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003790
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791- Compiler now generates simpler and faster code for dictionary
3792 literals. The oparg for BUILD_MAP now indicates an estimated
3793 dictionary size. There is a new opcode, STORE_MAP, for adding
3794 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003795
Georg Brandl3ee81df2008-05-17 18:14:43 +00003796- Issue #1638: %zd configure test fails on Linux.

3824 file can now be directly executed by passing their name to the
3825 interpreter. The directory/zipfile is automatically inserted as the
3826 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003827
Georg Brandl3ee81df2008-05-17 18:14:43 +00003828- Issue #1265: Fix a problem with sys.settrace, if the tracing
3829 function uses a generator expression when at the same time the
3830 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003831
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003832- sets and frozensets now have an isdisjoint() method.
3833
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003834- optimize the performance of builtin.sum().
3835
Neal Norwitz44f326e2007-10-05 05:29:17 +00003836- Fix warnings found by the new version of the Coverity checker.
3837
Georg Brandl3ee81df2008-05-17 18:14:43 +00003838- The enumerate() builtin function is no longer bounded to sequences
3839 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3840 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003841
Georg Brandl3ee81df2008-05-17 18:14:43 +00003842- Issue #1686386: Tuple's tp_repr did not take into account the
3843 possibility of having a self-referential tuple, which is possible
3844 from C code. Nor did object's tp_str consider that a type's tp_str
3845 could do something that could lead to an inifinite recursion.
3846 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3847 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003848
Georg Brandl3ee81df2008-05-17 18:14:43 +00003849- Issue #1164: It was possible to trigger deadlock when using the
3850 'print' statement to write to a file since the GIL was not released
3851 as needed. Now PyObject_Print() does the right thing along with
3852 various tp_print implementations of the built-in types and those in
3853 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003854
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Issue #1147: Exceptions were directly allowing string exceptions in
3856 their throw() method even though string exceptions no longer
3857 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003858
Georg Brandl3ee81df2008-05-17 18:14:43 +00003859- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003862- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863 PyObject_Call() never calling back out to Python code to trigger
3864 recursion depth updates/checks. Required the creation of a static
3865 RuntimeError instance in case normalizing an exception put the
3866 recursion check value past its limit. Fixes crashers
3867 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003868
Georg Brandl3ee81df2008-05-17 18:14:43 +00003869- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003882- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003883 __*__ attributes. (Some already existed, e.g., __doc__ and
3884 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003885
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003886- Add -3 option to the interpreter to warn about features that are
3887 deprecated and will be changed/removed in Python 3.0.
3888
Georg Brandl2134e752007-05-21 20:34:16 +00003889- Patch #1686487: you can now pass any mapping after '**' in function
3890 calls.
3891
Collin Winter62903052007-05-18 23:11:24 +00003892- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003893 "except E as target:". This is to provide forwards compatibility

Brett Cannon229cee22007-05-05 01:34:02 +00003896- Deprecate BaseException.message as per PEP 352.
3897
Georg Brandl3ee81df2008-05-17 18:14:43 +00003898- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003899 inherited from a builtin base.
3900
Vinay Sajip8549ce32007-05-06 17:53:37 +00003901- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003902 setting a plain string, ie don't expand to single letter identifiers.
3903
Raymond Hettinger13936692007-04-11 18:40:58 +00003904- Request #1191699: Slices can now be pickled.
3905
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003906- Request #1193128: str.translate() now allows a None argument for
3907 translations that only remove characters without re-mapping the
3908 remaining characters.
3909
Georg Brandl5cb76c12007-03-21 09:00:39 +00003910- Patch #1682205: a TypeError while unpacking an iterable is no longer
3911 masked by a generic one with the message "unpack non-sequence".
3912
Neal Norwitzaa754b72007-03-21 06:39:48 +00003913- Remove unused file Python/fmod.c.
3914
Guido van Rossum143b5642007-03-23 04:58:42 +00003915- Bug #1683368: The object.__init__() and object.__new__() methods are
3916 now stricter in rejecting excess arguments. The only time when
3917 either allows excess arguments is when it is not overridden and the
3918 other one is. For backwards compatibility, when both are
3919 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003920 warning later). Also, type.__init__() insists on the same signature
3921 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003922
Georg Brandl3ee81df2008-05-17 18:14:43 +00003923- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3924 object to complex using its __complex__() method before falling back
3925 to the __float__() method. Therefore, the functions in the cmath
3926 module now can operate on objects that define a __complex__()
3927 method.

3944
Georg Brandl7b9c5552007-03-12 14:30:05 +00003945- Bug #1678647: write a newline after printing an exception in any
3946 case, even when converting the value to a string failed.
3947
Georg Brandl871f1bc2007-03-12 13:17:36 +00003948- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003949 its argument, if it exists. If not, it will work like before. This
3950 allows customizing the output of dir() in the presence of a
3951 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003953- Patch #922167: Python no longer segfaults when faced with infinitely
3954 self-recursive reload() calls (as reported by bug #742342).
3955

3960 parthensized forms. This means complex(repr(x)) now works instead of
3961 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003962
Georg Brandlaa2321b2007-03-07 00:40:28 +00003963- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003964 makes the filenames the warning module prints much more sensible
3965 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003966

Georg Brandl0fca97a2007-03-05 22:28:08 +00003978- Patch #1674228: when assigning a slice (old-style), check for the
3979 sq_ass_slice instead of the sq_slice slot.
3980
Georg Brandl3ee81df2008-05-17 18:14:43 +00003981- When printing an unraisable error, don't print exceptions. before
3982 the name. This duplicates the behavior whening normally printing
3983 exceptions.

3992 created a weakref on itself during a __del__ call for new-style
3993 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00004033- Bug #1545497: when given an explicit base, int() did ignore NULs
4034 embedded in the string to convert.
4035
Georg Brandl846f73a2006-10-08 07:11:54 +00004036- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004084 generator expressions (x for x, in ... ) works again. Fixing this
4085 problem required changing the .pyc magic number. This means that
4086 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4894 with RFC 3207 and forgets any knowledge obtained from the server not
4895 obtained from the TLS negotiation itself. Patch contributed by Bill
4896 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004897
Georg Brandl3ee81df2008-05-17 18:14:43 +00004898- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004899 that the SMTP.starttls() caller no longer needs to call ehlo()
4900 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004901 does not claim to support starttls. Adds the
4902 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005001 time so that opening a database previously created with the DB_DUP
5002 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5003 opens. Specifically: dictionary assignment to a DB object will
5004 replace all values for a given key when the database allows
5005 duplicate values. DB users should use DB.put(k, v) when they want
5006 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005007

5013 characters with ASCII value less than 32. Also, it correctly quotes
5014 dots only if they occur on a single line, as opposed to the previous
5015 behavior of quoting dots if they are the second character of any
5016 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005017

Georg Brandl3ee81df2008-05-17 18:14:43 +00005422- Removed the macfs module. It had been deprecated since Python 2.5.
5423 This lead to the deprecation of macostools.touched() as it relied
5424 solely on macfs and was a no-op under OS X.
