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

506
Mark Dickinsonb678de82009-11-19 18:41:49 +0000507- Issue #7117: repr(x) for a float x returns a result based on the
508 shortest decimal string that's guaranteed to round back to x under
509 correct rounding (with round-half-to-even rounding mode).
510 Previously it gave a string based on rounding x to 17 decimal digits.
511 repr(x) for a complex number behaves similarly. On platforms where
512 the correctly-rounded strtod and dtoa code is not supported (see below),
513 repr is unchanged.
514
515- Issue #7117: On almost all platforms: float-to-string and
516 string-to-float conversions within Python are now correctly rounded.
517 Places these conversions occur include: str for floats and complex
518 numbers; the float and complex constructors; old-style and new-style
519 numeric formatting; serialization and deserialization of floats and
520 complex numbers using marshal, pickle and json; parsing of float and
521 imaginary literals in Python code; Decimal-to-float conversion.
522
523 The conversions use a Python-adapted version of David Gay's
524 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
525 functions. This code is supported on Windows, and on Unix-like
526 platforms using gcc, icc or suncc as the C compiler. There may be a
527 small number of platforms on which correct operation of this code
528 cannot be guaranteed, so the code is not used: notably, this applies
529 to platforms where the C double format is not IEEE 754 binary64, and
530 to platforms on x86 hardware where the x87 FPU is set to 64-bit
531 precision and Python's configure script is unable to determine how
532 to change the FPU precision. On these platforms conversions use the
533 platform strtod and dtoa, as before.
534
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000535- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000536 now uses the correctly-rounded string <-> float conversions
537 described above (when available), and so produces correctly rounded
538 results that will display nicely under the float repr. There are
539 two related small changes: (1) round now accepts any class with an
540 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000541 floats for the second argument), and (2) an excessively large second
542 integer argument (e.g., round(1.234, 10**100)) no longer raises an
543 exception.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000671- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
672 statement and correctly lookup the __enter__ and __exit__ special methods.
673
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000674- Issue #5829: complex("1e500") no longer raises OverflowError. This
675 makes it consistent with float("1e500") and interpretation of real
676 and imaginary literals.
677

684
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000685- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
686 (1) inf and nan strings with trailing whitespace were incorrectly
687 rejected; (2) parsing of strings representing infinities and nans
688 was locale aware; and (3) the interpretation of fromhex('-nan')
689 didn't match that of float('-nan').
690
Eric Smitha985a3a2009-05-05 18:26:08 +0000691- Issue #5920: For float.__format__, change the behavior with the
692 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
693 to be like 'g' but with at least one decimal point and with a
694 default precision of 12. Previously, the behavior the same but with
695 a default precision of 6. This more closely matches str(), and
696 reduces surprises when adding alignment flags to the empty
697 presentation type. This also affects the new complex.__format__ in
698 the same way.
699
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000700- Issue #5890: in subclasses of 'property' the __doc__ attribute was
701 shadowed by classtype's, even if it was None. property now
702 inserts the __doc__ into the subclass instance __dict__.

728 floats, ints, and longs.
729
730- Issue #5515: 'n' formatting for ints, longs, and floats handles
731 leading zero formatting poorly.
732

740 some builtin types.
741
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000742- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000743 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000744
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000745- Issue #5759: float() didn't call __float__ on str subclasses.

761
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000762- Issue #4688: Add a heuristic so that tuples and dicts containing only
763 untrackable objects are not tracked by the garbage collector. This can
764 reduce the size of collections and therefore the garbage collection overhead
765 on long-running programs, depending on their particular use of datatypes.
766
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000767- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

769 are now between 50% and 150% faster.
770
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000771- Issue #4258: Make it possible to use base 2**30 instead of base
772 2**15 for the internal representation of integers, for performance
773 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
774 --enable-big-digits option to configure, which overrides the
775 default. Add sys.long_info structseq to provide information about
776 the internal format.
777
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000778- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
779 result traceback.__members__ no longer exists.)
780
Mark Dickinson6b265f12009-03-18 16:07:26 +0000781- Issue #4474: PyUnicode_FromWideChar now converts characters outside
782 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

784
Eric Smith6f42edb2009-03-14 11:57:26 +0000785- Issue #5237: Allow auto-numbered fields in str.format(). For
786 example: '{} {}'.format(1, 2) == '1 2'.
787
Brett Cannon6c4cff02009-03-11 04:51:06 +0000788- Issue #3652: Make the 'line' argument for warnings.showwarning() a
789 requirement. Means the DeprecationWarning from Python 2.6 can go away.
790
Eric Smithe9fb6862009-02-20 14:02:36 +0000791- Issue #5247: Improve error message when unknown format codes are
792 used when using str.format() with str, unicode, long, int, and
793 float arguments.
794
Raymond Hettinger08259e82009-02-18 23:10:19 +0000795- Running Python with the -3 option now also warns about classic division
796 for ints and longs.
797
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000798- Issue #5260: Long integers now consume less memory: average
799 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
800 on a 64-bit system.
801
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000802- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
803 rotating the object pointer by 4 bits to the right.
804
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000805- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
806 it now forces its argument to double before testing for infinity.
807
Benjamin Petersone18ef192009-01-20 14:21:16 +0000808- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
809
Georg Brandl29c6a282009-04-05 20:23:13 +0000810- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000811 were suppressing all exceptions. These include list(), filter(), map(),
812 zip(), and bytearray().
813
Benjamin Peterson596d3062009-01-19 15:42:23 +0000814- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
815 functions.
816

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000833- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
834 collecting the oldest generation) so that allocating lots of objects without
835 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000836 Martin von Löwis at

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

929
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000930- Issue #4069: When set.remove(element) is used with a set element, the element

954 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
955 step. This avoids problems with counting UTF-8 bytes that ignores the effect
956 of using the replace error handler in PyUnicode_DecodeUTF8().
957
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000958- Issue #3739: The unicode-internal encoder now reports the number of characters

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

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002344- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2345
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002346- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2347 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2348 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2349 ``printf`` function, whereas PyString_FromFormat has an independent
2350 implementation and uses "%zd" on all platforms for size_t values.
2351 This makes a difference on win64, where ``printf`` needs "%Id" to display
2352 64bit values.
2353
Benjamin Peterson97179b02008-09-09 20:55:01 +00002354- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2358 object; previously an int would be returned for small values. the __long__
2359 method is allowed to return either an int or a long, but the behaviour of
2360 float objects should not change to respect backward compatibility.
2361
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002362- Issue #3751: str.rpartition would perform a left-partition when called with
2363 a unicode argument.
2364
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002365- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002368 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002369 was correctly parsed but parsing of subsequent arguments failed.
2370
Vinay Sajip35e3b032008-09-01 14:33:59 +00002371- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002372 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2373 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2374 when given a tuple of classes as second argument, were looking up
2375 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2376 type object.
2377
Neal Norwitz18aa3882008-08-24 05:04:52 +00002378- Fix crashes on memory allocation failure found with failmalloc.
2379
2380- Fix memory leaks found with valgrind and update suppressions file.
2381
2382- Fix compiler warnings in opt mode which would lead to invalid memory reads.

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

2521-----------------
2522
Guido van Rossumf8402962008-08-20 15:01:50 +00002523- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2524 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2525 extensions do not automatically benefit from the class attribute
2526 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2527 to their tp_flags field if they care. This is a backwards
2528 compatibility feature; in 3.0, all types will use the cache by
2529 default.
2530
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002531- Keyword arguments can now follow starred arguments. (``f(a, *args,
2532 keyword=23)`` is now valid syntax.)
2533
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002534- ctypes function pointers that are COM methods have a boolean True
2535 value again.
2536
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002537- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2538 by denying s# to parse objects that have a releasebuffer procedure,
2539 and introducing s*.
2540
Georg Brandl1e13ea92008-08-11 09:07:59 +00002541- Issue #3537: Fix an assertion failure when an empty but presized dict
2542 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00002544- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2545 ValueError consistently across platforms.
2546
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002547- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2548 (64bit Unix, for example), unichr() would truncate its argument and return
2549 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2550
Neal Norwitze7d8be82008-07-31 17:17:14 +00002551- Apply security patches from Apple.
2552
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002553- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00002556- Issue #1819: function calls with several named parameters are now on
2557 average 35% faster (as measured by pybench).
2558
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002559- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2560 the python debugger steps into a class statement: the free variables (local
2561 variables defined in an outer scope) would be deleted from the outer scope.
2562
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002563- Issue #2620: Overflow checking when allocating or reallocating memory
2564 was not always being done properly in some python types and extension
2565 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2566 all been updated to perform better checks and places in the code that
2567 would previously leak memory on the error path when such an allocation
2568 failed have been fixed.

2574
Benjamin Petersone977ad42008-08-20 01:42:01 +00002575- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2576 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2577
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002578- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2579 version reported by these tools does not necessarily follow the python
2580 version numbering scheme, so the module is less strict when parsing it.
2581
Nick Coghlanf70385a2008-08-18 12:42:46 +00002582- Issue #2235: Added Py3k warnings for types which will become unhashable
2583 under the stricter __hash__ inheritance rules in 3.0. Several types
2584 which did not meet the rules for hash invariants and were already
2585 unhashable in 3.0 have now been explicitly flagged as unhashable in
2586 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2587 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2588
Brett Cannon88f801d2008-08-18 00:46:22 +00002589- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2590 imported into the module but exposed as part of the module's API.
2591

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002598- Issue #3575: Incremental decoder's decode function now takes bytearray
2599 by using 's*' instead of 't#'.
2600
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002601- Issue #2222: Fixed reference leak when occurred os.rename()

2611 after a 302 response in the case of not going through a proxy.
2612
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002613- Issue #2676: in the email package, content-type parsing was hanging on
2614 pathological input because of quadratic or exponential behaviour of a
2615 regular expression.
2616
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002617- Issue #3476: binary buffered reading through the new "io" library is now
2618 thread-safe.
2619
Brett Cannonbf3157b2008-08-14 05:00:03 +00002620- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2621 since mimetools itself is deprecated. Because modules are cached, all
2622 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2623
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002624- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002626- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2627 menu entries were not deleted.
2628
Brett Cannon83e81842008-08-09 23:30:55 +00002629- Copied the implementation of reduce() to _functools.reduce() to have a
2630 version that did not raise a DeprecationWarning under -3.
2631
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002632- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2633 a MemoryError rather than silently stop the iteration.
2634
Guido van Rossum59ce9012008-08-09 14:55:34 +00002635- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2636 to _sre.compile() will now be rejected. This should not affect anybody
2637 since the re.compile() function never generates invalid re-bytecode.
2638
Skip Montanaroa032bf42008-08-08 22:52:51 +00002639- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2640 upon first access it can be automatically initialized from the csv file if
2641 it wasn't initialized during instantiation.
2642
Brett Cannon3aa2a492008-08-06 22:28:09 +00002643- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2644 the reload() built-in has been removed.
2645
Brett Cannon7e30b672008-08-04 21:52:25 +00002646- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002647 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2655 raised an AttributeError.
2656
Benjamin Peterson01a24322008-07-28 23:35:27 +00002657- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002658 asking for a specific length. This problem only affected files opened
2659 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002660

2683
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002684- Issue #3394: zipfile.writestr sets external attributes when passed a
2685 file name rather than a ZipInfo instance, so files are extracted with
2686 mode 0600 rather than 000 under Unix.
2687
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002688- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2689 argument in python 2.5, this broke code that subclassed Popen to include its
2690 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2699
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002700- Issue #2235: the C API function PyObject_HashNotImplemented and its
2701 interaction with the tp_hash slot (added in 2.6b2) are now documented
2702
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002703- Issue #643841: The language reference now provides more detailed
2704 coverage of the lookup process for special methods. The disclaimers
2705 regarding lack of coverage of new-style classes have also been
2706 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002709What's New in Python 2.6 beta 2?
2710================================
2711
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002712*Release date: 17-Jul-2008*
2713
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002714Core and Builtins
2715-----------------
2716
Georg Brandl3e483f62008-07-16 22:57:41 +00002717- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2718 its methods now allow for items objects that can be converted to
2719 an integer using operator.index().
2720
Mark Dickinson64b7e502008-07-16 09:40:03 +00002721- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2722 produced a ValueError instead of giving the correct float.
2723
Eric Smitha5fa5a22008-07-16 00:11:49 +00002724- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2725 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2726
Mark Dickinson7103aa42008-07-15 19:08:33 +00002727- Issue #3008: the float type has a new instance method 'float.hex'
2728 and a new class method 'float.fromhex' to convert floating-point
2729 numbers to and from hexadecimal strings, respectively.
2730
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002731- Issue #2235: __hash__ is once again inherited by default. To allow
2732 collections.Hashable to remain meaningful in the presence of the
2733 default hash implementation (object.__hash__), it is now possible
2734 to explicit block inheritance of hash by setting __hash__=None at
2735 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2736 level.
2737
Nick Coghlanb028f502008-07-13 14:52:36 +00002738- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2739 the parent module cannot be found while performing an absolute import.
2740 This means that an incorrectly defined __package__ attribute will
2741 now only prevent relative imports in that module rather than causing
2742 all imports from that module to fail.
2743
Nick Coghlan14ff9942008-07-08 14:21:42 +00002744- Issue #2517: Allow unicode messages in Exceptions again by correctly
2745 bypassing the instance dictionary when looking up __unicode__ on
2746 new-style classes.
2747
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002748- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2749 set to a custom object whose write() method happens to install
2750 another file in sys.stdout.
2751
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002752- Issue #3088: Corrected a race condition in classes derived from
2753 threading.local: the first member set by a thread could be saved in
2754 another thread's dictionary.
2755
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002756- Issue #3004: Minor change to slice.indices(): the start and stop
2757 arguments are now treated identically, making the behaviour easier
2758 to describe and understand. For example, slice(None, -10,
2759 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2760 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2761 10, -1).
2762
Georg Brandl278fc502008-07-19 12:46:12 +00002763- Issue #3219: Calling a function with repeated keyword arguments,
2764 f(a=2, a=23), would not cause a syntax error. This was a regression
2765 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002766
Georg Brandl278fc502008-07-19 12:46:12 +00002767- Issue #2862: Make int and float freelist management consistent with
2768 other freelists. Changes their CompactFreeList apis into
2769 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002770

2772-------
2773
Thomas Heller57adf222008-08-14 19:10:48 +00002774- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2775 api functions without holding the GIL, which could lead to a fatal
2776 error when they failed.
2777
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002778- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002786- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2787 ForkingPickler.register() to resolve conflict with ctypes.
2788
Vinay Sajip51e65192008-07-18 09:01:10 +00002789- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002790
Thomas Heller880f5292008-07-15 19:39:38 +00002791- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2792 a valid dlerror() message.
2793
Thomas Heller2bad6572008-07-15 17:19:50 +00002794- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2795 incomplete structure was created.
2796
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002797- Issue #3339: dummy_thread.acquire() should not return None.

2800
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002801- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002802
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002803- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2804 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002805 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002806 content-length. The problem had been corrected in the 2.4 branch, but never
2807 merged into trunk.
2808
Georg Brandle78fbcc2008-07-05 10:13:36 +00002809- Issue #2663: add filtering capability to shutil.copytree().

2815- Issue #1746: Correct handling of zipfile archive comments (previously
2816 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002817 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002818
Vinay Sajip51e65192008-07-18 09:01:10 +00002819- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002820 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002821
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002822- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2823 handling is now the same as that of other special attributes like __name__).
2824
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002825- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2826 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00003215 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003216
3217 This is controlled by the configure argument ``--with-universal-archs``:
3218
3219 - ``--with-universal-archs=all``: install 4-way universal
3220
3221 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3222
3223 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3224
3225 This option should be used in combination with ``--enable-universalsdk=``.
3226
3227 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 +00003277- Issue #1631171: Re-implement the 'warnings' module in C (the
3278 original Python code has been kept as backup). This will allow for
3279 using the 'warning's machinery in such places as the parser where
3280 use of pure Python code is not possible. Both the ``showarning()``
3281 and ``formatwarning()`` gain an optional 'line' argument which is
3282 not called by default for backwards-compatibility reasons. Setting
3283 ``warnings.showwarning()`` to an implementation that lacks support
3284 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003347- Issue #2550: The approach used by client/server code for obtaining
3348 ports to listen on in network-oriented tests has been refined in an
3349 effort to facilitate running multiple instances of the entire
3350 regression test suite in parallel without issue.
3351 test_support.bind_port() has been fixed such that it will always
3352 return a unique port -- which wasn't always the case with the
3353 previous implementation, especially if socket options had been set
3354 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3355 new implementation of bind_port() will actually raise an exception
3356 if it is passed an AF_INET/SOCK_STREAM socket with either the
3357 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3358 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3359 the socket it's been passed. This currently only applies to
3360 Windows. This option prevents any other sockets from binding to the
3361 host/port we've bound to, thus removing the possibility of the
3362 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3363 when a second SOCK_STREAM socket binds and accepts to a host/port
3364 that's already been bound by another socket. The optional preferred
3365 port parameter to bind_port() has been removed. Under no
3366 circumstances should tests be hard coding ports!
3367
3368 test_support.find_unused_port() has also been introduced, which will
3369 pass a temporary socket object to bind_port() in order to obtain an
3370 unused port. The temporary socket object is then closed and
3371 deleted, and the port is returned. This method should only be used
3372 for obtaining an unused port in order to pass to an external program
3373 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3374 a parameter to a server-oriented class that doesn't give you direct
3375 access to the underlying socket used.
3376
3377 Finally, test_support.HOST has been introduced, which should be used
3378 for the host argument of any relevant socket calls (i.e. bind and
3379 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003380
3381 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3384 test_asynchat and test_socket_ssl.
3385
Georg Brandl3ee81df2008-05-17 18:14:43 +00003386 It is now possible for multiple instances of the regression test

3655
Fred Drakea8ee94b2008-03-01 02:45:07 +00003656- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003657 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003658
Georg Brandlad61bc82008-02-23 15:11:18 +00003659- Issue #2067: file.__exit__() now calls subclasses' close() method.
3660
3661- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003662
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003663- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003664 issue 215555 for a discussion.
3665
Eric Smitha73fbe72008-02-23 03:09:44 +00003666- Added the future_builtins module, which contains hex() and oct().
3667 These are the PEP 3127 version of these functions, designed to be
3668 compatible with the hex() and oct() builtins from Python 3.0. They
3669 differ slightly in their output formats from the existing, unchanged
3670 Python 2.6 builtins. The expected usage of the future_builtins
3671 module is:
3672 from future_builtins import hex, oct
3673
Eric Smith7ef40bf2008-02-20 23:34:22 +00003674- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3675 exponents for exponents with absolute value < 100. Follows C99
3676 standard. This is a change on Windows, which would use 3 digits.
3677 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3678 so that any alterations it does to the resulting string will be
3679 available in stringlib/formatter.h (for float.__format__).
3680
Eric Smith5a3c1352008-02-19 13:21:56 +00003681- Implemented PEP 3101, Advanced String Formatting. This adds a new
3682 builtin format(); a format() method for str and unicode; a
3683 __format__() method to object, str, unicode, int, long, float, and
3684 datetime; the class string.Formatter; and the C API
3685 PyObject_Format().
3686
Georg Brandl3ee81df2008-05-17 18:14:43 +00003687- Fixed several potential crashes, all caused by specially crafted
3688 __del__ methods exploiting objects in temporarily inconsistent
3689 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003690
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003691- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003692 prevent a possible crash: an Abstract Base Class would try to access
3693 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003694
Georg Brandl3ee81df2008-05-17 18:14:43 +00003695- Fixed repr() and str() of complex numbers with infinity or nan as
3696 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003697
Georg Brandl3ee81df2008-05-17 18:14:43 +00003698- Clear all free lists during a gc.collect() of the highest generation
3699 in order to allow pymalloc to free more arenas. Python may give back
3700 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003701
Georg Brandl3ee81df2008-05-17 18:14:43 +00003702- Issue #2045: Fix an infinite recursion triggered when printing a
3703 subclass of collections.defaultdict, if its default_factory is set
3704 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003705
Christian Heimesf75dbef2008-02-08 00:11:31 +00003706- Fixed a minor memory leak in dictobject.c. The content of the free
3707 list was not freed on interpreter shutdown.
3708
Georg Brandl3ee81df2008-05-17 18:14:43 +00003709- Limit free list of method and builtin function objects to 256
3710 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003711
Georg Brandl3ee81df2008-05-17 18:14:43 +00003712- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3713 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003714 to compact the internal free lists of pre-allocted ints and floats.
3715
Georg Brandl3ee81df2008-05-17 18:14:43 +00003716- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3717 calls. Python expected the return type int but the fork familie
3718 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003719
Georg Brandl3ee81df2008-05-17 18:14:43 +00003720- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3721 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003722
Georg Brandl3ee81df2008-05-17 18:14:43 +00003723- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3724 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003725
Georg Brandl3ee81df2008-05-17 18:14:43 +00003726- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3727 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003728
Georg Brandl3ee81df2008-05-17 18:14:43 +00003729- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3730 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003731
Georg Brandl3ee81df2008-05-17 18:14:43 +00003732- Patch #1473257: generator objects gain a gi_code attribute. This is
3733 the same object as the func_code attribute of the function that
3734 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003735
Georg Brandl3ee81df2008-05-17 18:14:43 +00003736- Issue #1920: "while 0" statements were completely removed by the
3737 compiler, even in the presence of an "else" clause, which is
3738 supposed to be run when the condition is false. Now the compiler
3739 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003740
Guido van Rossumeead05f2008-01-24 18:21:02 +00003741- A few crashers fixed: weakref_in_del.py (issue #1377858);
3742 loosing_dict_ref.py (issue #1303614, test67.py);
3743 borrowed_ref_[34].py (not in tracker).
3744
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003745- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003746 suppressed while an extension is loaded by calling SetErrorMode in
3747 dynload_win.c. The error is still reported properly.
3748
Georg Brandl3ee81df2008-05-17 18:14:43 +00003749- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003750 several extension methods and modules do not work without unicode
3751 support.
3752
Georg Brandl26543b12008-01-21 18:36:51 +00003753- Issue #1882: when compiling code from a string, encoding cookies in the
3754 second line of code were not always recognized correctly.
3755
Georg Brandl14404b62008-01-19 19:27:05 +00003756- Issue #1679: "0x" was taken as a valid integer literal.
3757
Georg Brandl6caad7d2008-01-26 14:19:22 +00003758- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003759 added.
3760
Christian Heimesc94e2b52008-01-14 04:13:37 +00003761- sys.float_info / PyFloat_GetInfo: The floating point information
3762 object was converted from a dict to a specialized structseq object.
3763
Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Patch #1816: Added sys.flags structseq. It exposes the status of
3765 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003766
Georg Brandl3ee81df2008-05-17 18:14:43 +00003767- Objects/structseq.c: Implemented new structseq representation. The
3768 patch makes structseqs (e.g. the return value of os.stat) more
3769 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003770
Georg Brandl3ee81df2008-05-17 18:14:43 +00003771- Patch #1700288: added a type attribute cache that caches method
3772 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003773
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003774- Bug #1776: __import__() no longer accepts filenames on any platform.
3775 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003776

3778
Georg Brandl3ee81df2008-05-17 18:14:43 +00003779- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3780 envvar and sys.dont_write_bytecode attribute. All these can be set
3781 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003782
Georg Brandl3ee81df2008-05-17 18:14:43 +00003783- Improve some exception messages when Windows fails to load an
3784 extension module. Now we get for example '%1 is not a valid Win32
3785 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003786
Georg Brandl3ee81df2008-05-17 18:14:43 +00003787- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003789- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3790 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003791
Christian Heimes0a8143f2007-12-18 23:22:54 +00003792- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003793 and INF. float("nan"), float("inf") and float("-inf") now work on
3794 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003795
Georg Brandl3ee81df2008-05-17 18:14:43 +00003796- Compiler now generates simpler and faster code for dictionary
3797 literals. The oparg for BUILD_MAP now indicates an estimated
3798 dictionary size. There is a new opcode, STORE_MAP, for adding
3799 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003800
Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- Issue #1638: %zd configure test fails on Linux.

3814 __package__ attribute.
3815
Georg Brandl3ee81df2008-05-17 18:14:43 +00003816- Issue #1402: Fix a crash on exit, when another thread is still
3817 running, and if the deallocation of its frames somehow calls the
3818 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003819

3829 file can now be directly executed by passing their name to the
3830 interpreter. The directory/zipfile is automatically inserted as the
3831 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003832
Georg Brandl3ee81df2008-05-17 18:14:43 +00003833- Issue #1265: Fix a problem with sys.settrace, if the tracing
3834 function uses a generator expression when at the same time the
3835 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003836
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003837- sets and frozensets now have an isdisjoint() method.
3838
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003839- optimize the performance of builtin.sum().
3840
Neal Norwitz44f326e2007-10-05 05:29:17 +00003841- Fix warnings found by the new version of the Coverity checker.
3842
Georg Brandl3ee81df2008-05-17 18:14:43 +00003843- The enumerate() builtin function is no longer bounded to sequences
3844 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3845 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003846
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847- Issue #1686386: Tuple's tp_repr did not take into account the
3848 possibility of having a self-referential tuple, which is possible
3849 from C code. Nor did object's tp_str consider that a type's tp_str
3850 could do something that could lead to an inifinite recursion.
3851 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3852 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003853
Georg Brandl3ee81df2008-05-17 18:14:43 +00003854- Issue #1164: It was possible to trigger deadlock when using the
3855 'print' statement to write to a file since the GIL was not released
3856 as needed. Now PyObject_Print() does the right thing along with
3857 various tp_print implementations of the built-in types and those in
3858 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003859
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860- Issue #1147: Exceptions were directly allowing string exceptions in
3861 their throw() method even though string exceptions no longer
3862 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003863
Georg Brandl3ee81df2008-05-17 18:14:43 +00003864- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003867- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003868 PyObject_Call() never calling back out to Python code to trigger
3869 recursion depth updates/checks. Required the creation of a static
3870 RuntimeError instance in case normalizing an exception put the
3871 recursion check value past its limit. Fixes crashers
3872 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003873
Georg Brandl3ee81df2008-05-17 18:14:43 +00003874- Patch #1031213: Decode source line in SyntaxErrors back to its

Georg Brandl3ee81df2008-05-17 18:14:43 +00003888 __*__ attributes. (Some already existed, e.g., __doc__ and
3889 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003890
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003891- Add -3 option to the interpreter to warn about features that are
3892 deprecated and will be changed/removed in Python 3.0.
3893
Georg Brandl2134e752007-05-21 20:34:16 +00003894- Patch #1686487: you can now pass any mapping after '**' in function

Collin Winter62903052007-05-18 23:11:24 +00003897- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003898 "except E as target:". This is to provide forwards compatibility
3899 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00003901- Deprecate BaseException.message as per PEP 352.
3902
Georg Brandl3ee81df2008-05-17 18:14:43 +00003903- Issue #1303614: don't expose object's __dict__ when the dict is

3905
Vinay Sajip8549ce32007-05-06 17:53:37 +00003906- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003907 setting a plain string, ie don't expand to single letter identifiers.
3908
Raymond Hettinger13936692007-04-11 18:40:58 +00003909- Request #1191699: Slices can now be pickled.

Guido van Rossum143b5642007-03-23 04:58:42 +00003920- Bug #1683368: The object.__init__() and object.__new__() methods are
3921 now stricter in rejecting excess arguments. The only time when
3922 either allows excess arguments is when it is not overridden and the
3923 other one is. For backwards compatibility, when both are
3924 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003925 warning later). Also, type.__init__() insists on the same signature
3926 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003928- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3929 object to complex using its __complex__() method before falling back
3930 to the __float__() method. Therefore, the functions in the cmath
3931 module now can operate on objects that define a __complex__()
3932 method.

3949
Georg Brandl7b9c5552007-03-12 14:30:05 +00003950- Bug #1678647: write a newline after printing an exception in any
3951 case, even when converting the value to a string failed.
3952
Georg Brandl871f1bc2007-03-12 13:17:36 +00003953- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003954 its argument, if it exists. If not, it will work like before. This
3955 allows customizing the output of dir() in the presence of a
3956 __getattr__().

3965 parthensized forms. This means complex(repr(x)) now works instead of
3966 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003967
Georg Brandlaa2321b2007-03-07 00:40:28 +00003968- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003969 makes the filenames the warning module prints much more sensible
3970 when a PYTHONSTARTUP file is used.

3984 sq_ass_slice instead of the sq_slice slot.
3985
Georg Brandl3ee81df2008-05-17 18:14:43 +00003986- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004521 AttributeError instead of an IOError when the server's response

4613 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00004898- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4899 with RFC 3207 and forgets any knowledge obtained from the server not
4900 obtained from the TLS negotiation itself. Patch contributed by Bill
4901 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004902
Georg Brandl3ee81df2008-05-17 18:14:43 +00004903- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004904 that the SMTP.starttls() caller no longer needs to call ehlo()
4905 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004906 does not claim to support starttls. Adds the
4907 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4988 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4989 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005006 time so that opening a database previously created with the DB_DUP
5007 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5008 opens. Specifically: dictionary assignment to a DB object will
5009 replace all values for a given key when the database allows
5010 duplicate values. DB users should use DB.put(k, v) when they want
5011 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005012

5018 characters with ASCII value less than 32. Also, it correctly quotes
5019 dots only if they occur on a single line, as opposed to the previous
5020 behavior of quoting dots if they are the second character of any
5021 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005022

Georg Brandl3ee81df2008-05-17 18:14:43 +00005427- Removed the macfs module. It had been deprecated since Python 2.5.
5428 This lead to the deprecation of macostools.touched() as it relied
5429 solely on macfs and was a no-op under OS X.
