21 slice with very large step value.
22
Eric Smithee931b72010-01-27 00:28:29 +000023- Issue #7766: Change sys.getwindowsversion() return value to a named
24 tuple and add the additional members returned in an OSVERSIONINFOEX
25 structure. The new members are service_pack_major, service_pack_minor,
26 suite_mask, and product_type.
27
Antoine Pitroue80a6a42010-01-17 12:26:20 +000028- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
29 could crash in many places because of the PyByteArray_AS_STRING() macro
30 returning NULL. The macro now returns a statically allocated empty
31 string instead.
32
Antoine Pitrou64672132010-01-13 07:55:48 +000033- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
34 methods of bytes, bytearray and unicode objects by using a common
35 implementation based on stringlib's fast search. Patch by Florent Xicluna.
36
Mark Dickinson476279f2010-01-16 10:44:00 +000037- Issue #7632: Fix various str -> float conversion bugs present in 2.7
38 alpha 2, including: (1) a serious 'wrong output' bug that could
39 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
40 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000041 strings corresponding to subnormal values, (3) a memory leak for
42 some values large enough to cause overflow, and (4) a number of
43 flaws that could lead to incorrectly rounded results.
Mark Dickinson8efef5c2010-01-12 22:23:56 +000044
Brett Cannon3ffa43d2010-01-14 20:00:28 +000045- Issue #7319, #7770: Silence DeprecationWarning by default when -3 is not
46 used.

59
Antoine Pitrouf3fa0742010-01-31 22:26:04 +000060- Issue #6939: Fix file I/O objects in the `io` module to keep the original
61 file position when calling `truncate()`. It would previously change the
62 file position to the given argument, which goes against the tradition of
63 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
64
Benjamin Petersone06f7112010-01-28 02:15:02 +000065- UserDict is now a new-style class.
66
Antoine Pitrou94c33eb2010-01-27 20:59:50 +000067- Issue #7610: Reworked implementation of the internal
68 :class:`zipfile.ZipExtFile` class used to represent files stored inside
69 an archive. The new implementation is significantly faster and can
70 be wrapped in a :class:`io.BufferedReader` object for more speedups.
71 It also solves an issue where interleaved calls to `read()` and
72 `readline()` give wrong results. Patch by Nir Aides.
73
Benjamin Peterson2deb5c72010-01-27 02:16:42 +000074- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Tarek Ziadéf14c7fc2010-01-24 00:33:32 +000081- Issue #7748: Since unicode values are supported for some metadata options
82 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
83 encoded string for them. This ensure that the upload and register commands
84 send the right values to PyPI without any error.
85
R. David Murrayed44dfa2010-01-16 05:15:17 +000086- Issue #1670765: Prevent email.generator.Generator from re-wrapping
87 headers in multipart/signed MIME parts, which fixes one of the sources of

Tarek Ziadédc0f4872010-01-11 22:50:29 +0000106- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since
107 Extension extra options may change the output without changing the .c
108 file). Initial patch by Collin Winter.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000145What's New in Python 2.7 alpha 2?
146=================================
147
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000148*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000149
150Core and Builtins
151-----------------
152
Benjamin Petersonecdae192010-01-04 00:43:01 +0000153- The __complex__ method is now looked up on the class of instances to make it
154 consistent with other special methods.
155
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000156- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
157 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
158
Mark Dickinson1b34d252010-01-01 17:27:30 +0000159- Issue #5080: A number of functions and methods previously produced a
160 DeprecationWarning when passed a float argument where an integer was
161 expected. These functions and methods now raise TypeError instead.
162 The majority of the effects of this change are in the extension
163 modules, but some core functions and methods are affected: notably
164 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
165 methods.
166
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000167- Issue #7604: Deleting an unset slotted attribute did not raise an
168 AttributeError.

175
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000176- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
177 used to drop the time part of the result.
178
Mark Dickinson46572832009-12-27 14:55:57 +0000179- Issue #1811: improve accuracy and cross-platform consistency for
180 true division of integers: the result of a/b is now correctly
181 rounded for ints a and b (at least on IEEE 754 platforms), and in
182 particular does not depend on the internal representation of a long.
183
Ezio Melottif84caf42009-12-24 22:25:17 +0000184- Issue #6108: unicode(exception) and str(exception) should return the same
185 message when only __str__ (and not __unicode__) is overridden in the subclass.
186
Ronald Oussoren92919a62009-12-24 13:30:58 +0000187- Issue #6834: replace the implementation for the 'python' and 'pythonw'
188 executables on OSX.
189
190 These executables now work properly with the arch(1) command:
191 ``arch -ppc python`` will start a universal binary version of python
192 in PPC mode (unlike previous releases).
193
R. David Murray0a0a1a82009-12-14 16:28:26 +0000194- Issue #1680159: unicode coercion during an 'in' operation no longer masks
195 the underlying error when the coercion fails for the left hand operand.
196
Benjamin Peterson4895af42009-12-13 16:36:53 +0000197- Issue #7491: Metaclass's __cmp__ method was ignored.
198
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000199- Issue #7466: segmentation fault when the garbage collector is called

213 by Arfrever.
214
Antoine Pitrou80157252010-01-08 19:20:17 +0000215- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
216 renaming of `cPickle` to `pickle`. The warning was annoying since there's
217 no alternative to cPickle if you care about performance. Patch by Florent
218 Xicluna.
219

245 the Distutils upload command to avoid an error when PyPI reads it.
246 This occurs on long passwords. Initial patch by JP St. Pierre.
247
248- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000249 Patch by Tatsuhiro Tsujikawa.
250
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000251- Issue #7349: Make methods of file objects in the io module accept None as an
252 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
253 the same as passing no argument.
254
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000255- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000329- Issue #7419: setlocale() could crash the interpreter on Windows when called
330 with invalid values.
331
Eric Smithc4ab8332009-11-29 17:40:57 +0000332- Issue #3382: 'F' formatting for float and complex now convert the
333 result to upper case. This only affects 'inf' and 'nan', since 'f'
334 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000335
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000336- Remove switch from "%f" formatting to "%g" formatting for floats
337 larger than 1e50 in absolute value.
338
Mark Dickinson18cfada2009-11-23 18:46:41 +0000339- Remove restrictions on precision when formatting floats. E.g.,
340 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
341 requested 120 significant digits instead.
342
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000343- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000347- Issue #7085: Fix crash when importing some extensions in a thread
348 on MacOSX 10.6.
349
Mark Dickinsonb678de82009-11-19 18:41:49 +0000350- Issue #7117: repr(x) for a float x returns a result based on the
351 shortest decimal string that's guaranteed to round back to x under
352 correct rounding (with round-half-to-even rounding mode).
353 Previously it gave a string based on rounding x to 17 decimal digits.
354 repr(x) for a complex number behaves similarly. On platforms where
355 the correctly-rounded strtod and dtoa code is not supported (see below),
356 repr is unchanged.
357
358- Issue #7117: On almost all platforms: float-to-string and
359 string-to-float conversions within Python are now correctly rounded.
360 Places these conversions occur include: str for floats and complex
361 numbers; the float and complex constructors; old-style and new-style
362 numeric formatting; serialization and deserialization of floats and
363 complex numbers using marshal, pickle and json; parsing of float and
364 imaginary literals in Python code; Decimal-to-float conversion.
365
366 The conversions use a Python-adapted version of David Gay's
367 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
368 functions. This code is supported on Windows, and on Unix-like
369 platforms using gcc, icc or suncc as the C compiler. There may be a
370 small number of platforms on which correct operation of this code
371 cannot be guaranteed, so the code is not used: notably, this applies
372 to platforms where the C double format is not IEEE 754 binary64, and
373 to platforms on x86 hardware where the x87 FPU is set to 64-bit
374 precision and Python's configure script is unable to determine how
375 to change the FPU precision. On these platforms conversions use the
376 platform strtod and dtoa, as before.
377
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000378- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000379 now uses the correctly-rounded string <-> float conversions
380 described above (when available), and so produces correctly rounded
381 results that will display nicely under the float repr. There are
382 two related small changes: (1) round now accepts any class with an
383 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000384 floats for the second argument), and (2) an excessively large second
385 integer argument (e.g., round(1.234, 10**100)) no longer raises an
386 exception.
387

515 statement and correctly lookup the __enter__ and __exit__ special methods.
516
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000517- Issue #5829: complex("1e500") no longer raises OverflowError. This

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000528- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
529 (1) inf and nan strings with trailing whitespace were incorrectly
530 rejected; (2) parsing of strings representing infinities and nans
531 was locale aware; and (3) the interpretation of fromhex('-nan')
532 didn't match that of float('-nan').
533
Eric Smitha985a3a2009-05-05 18:26:08 +0000534- Issue #5920: For float.__format__, change the behavior with the
535 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
536 to be like 'g' but with at least one decimal point and with a
537 default precision of 12. Previously, the behavior the same but with
538 a default precision of 6. This more closely matches str(), and
539 reduces surprises when adding alignment flags to the empty
540 presentation type. This also affects the new complex.__format__ in
541 the same way.
542
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000543- Issue #5890: in subclasses of 'property' the __doc__ attribute was

611 improve its performance. Long divisions and remainder operations
612 are now between 50% and 150% faster.
613
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000614- Issue #4258: Make it possible to use base 2**30 instead of base
615 2**15 for the internal representation of integers, for performance
616 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
617 --enable-big-digits option to configure, which overrides the
618 default. Add sys.long_info structseq to provide information about
619 the internal format.
620
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000621- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
622 result traceback.__members__ no longer exists.)
623
Mark Dickinson6b265f12009-03-18 16:07:26 +0000624- Issue #4474: PyUnicode_FromWideChar now converts characters outside
625 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
626 and sizeof(Py_UNICODE) == 2.
627
Eric Smith6f42edb2009-03-14 11:57:26 +0000628- Issue #5237: Allow auto-numbered fields in str.format(). For
629 example: '{} {}'.format(1, 2) == '1 2'.
630
Brett Cannon6c4cff02009-03-11 04:51:06 +0000631- Issue #3652: Make the 'line' argument for warnings.showwarning() a
632 requirement. Means the DeprecationWarning from Python 2.6 can go away.
633
Eric Smithe9fb6862009-02-20 14:02:36 +0000634- Issue #5247: Improve error message when unknown format codes are
635 used when using str.format() with str, unicode, long, int, and
636 float arguments.
637
Raymond Hettinger08259e82009-02-18 23:10:19 +0000638- Running Python with the -3 option now also warns about classic division
639 for ints and longs.
640
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000641- Issue #5260: Long integers now consume less memory: average
642 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
643 on a 64-bit system.
644
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000645- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
646 rotating the object pointer by 4 bits to the right.

Mark Dickinsonc97c9092009-02-09 14:18:43 +0000648- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
649 it now forces its argument to double before testing for infinity.
650
Benjamin Petersone18ef192009-01-20 14:21:16 +0000651- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
652
Georg Brandl29c6a282009-04-05 20:23:13 +0000653- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000654 were suppressing all exceptions. These include list(), filter(), map(),
655 zip(), and bytearray().
656
Benjamin Peterson596d3062009-01-19 15:42:23 +0000657- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
658 functions.
659
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000660- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
661 OSError.

664
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000665- Issue #4935: The overflow checking code in the expandtabs() method common
666 to str, bytes and bytearray could be optimized away by the compiler, letting
667 the interpreter segfault instead of raising an error.
668
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000669- Issue #3720: Fix a crash when an iterator modifies its class and removes its
670 __next__ method.

675
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000676- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
677 collecting the oldest generation) so that allocating lots of objects without
678 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000679 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000680 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

683
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000684- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
685 an existing .py counterpart, override the co_filename attributes of all
686 code objects if the original filename is obsolete (which can happen if the
687 file has been renamed, moved, or if it is accessed through different paths).
688 Patch by Ziga Seilnacht and Jean-Paul Calderone.
689
Martin v. Löwis5344c992009-01-02 20:32:55 +0000690- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000692- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
693 file with `str' filename on Windows.
694
Antoine Pitrouaa687902009-01-01 14:11:22 +0000695- Issue #3680: Reference cycles created through a dict, set or deque iterator
696 did not get collected.
697
Nick Coghlan180e4002008-12-30 01:18:48 +0000698- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
699 where the tp_hash and tp_dict slots are both NULL.
700
Benjamin Peterson7af65562008-12-29 17:56:58 +0000701- Issue #4764: With io.open, IOError.filename is set when trying to open a
702 directory on POSIX systems.
703
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000704- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
705 systems.
706
Georg Brandl6425a2f2008-12-28 11:54:53 +0000707- Issue #4759: None is now allowed as the first argument of
708 bytearray.translate(). It was always allowed for bytes.translate().
709
Skip Montanarof205c132008-12-23 03:30:15 +0000710- Added test case to ensure attempts to read from a file opened for writing
711 fail.
712
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000713- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

721
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000722- Issue #4597: Fixed exception handling when the __exit__ function of a
723 context manager returns a value that cannot be converted to a bool.
724
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000725- Issue #4597: Fixed several opcodes that weren't always propagating
726 exceptions.
727
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000728- Issue #4445: Replace "sizeof(PyStringObject)" with
729 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
730 str instances. On a typical machine this saves 3 bytes of memory
731 (on average) per string allocation.
732
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000733- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
734 interpreter to abort ("Fatal Python error: Could not reset the stack!")
735 instead of throwing a MemoryError.
736
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000737- Issue #3689: The list reversed iterator now supports __length_hint__
738 instead of __len__. Behavior now matches other reversed iterators.
739
Benjamin Petersonc078f922008-11-21 22:27:24 +0000740- Issue #4367: Python would segfault during compiling when the unicodedata
741 module couldn't be imported and \N escapes were present.
742
Vinay Sajip213faca2008-12-03 23:22:58 +0000743- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000744 method on file objects with closefd=False. The file descriptor is still
745 kept open but the file object behaves like a closed file. The ``FileIO``
746 object also got a new readonly attribute ``closefd``.
747
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000748- Issue #4348: Some bytearray methods returned that didn't cause any change to
749 the bytearray, returned the same bytearray instead of a copy.
750
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000751- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
752
Benjamin Peterson273c2332008-11-17 22:39:09 +0000753- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
754
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000755- Issue #4048: The parser module now correctly validates relative imports.
756
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000757- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
758 exec statement.
759
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000760- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
761 method does not return iterators for the 4th and 5th items.
762
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000763- Issue #4209: Enabling unicode_literals and the print_function in the same
764 __future__ import didn't work.
765
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000766- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000767 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000768
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000769- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
770 returned a path longer than MAX_PATH. (But It's doubtful this code path is
771 really executed because I cannot move to such directory on win2k)
772
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000773- Issue #4069: When set.remove(element) is used with a set element, the element
774 is temporarily replaced with an equivalent frozenset. But the eventual
775 KeyError would always report the empty frozenset([]) as the missing key. Now
776 it correctly refers to the initial element.
777
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000778- Issue #4509: Various issues surrounding resize of bytearray objects to
779 which there are buffer exports.
780
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000781- Issue #4748: Lambda generators no longer return a value.

789
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000790- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
791 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000793- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
794 returned them on 64bit platforms.
795
Walter Dörwalded960ac2009-05-03 22:36:33 +0000796- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
797 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
798 step. This avoids problems with counting UTF-8 bytes that ignores the effect
799 of using the replace error handler in PyUnicode_DecodeUTF8().
800
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000801- Issue #3739: The unicode-internal encoder now reports the number of characters
802 consumed like any other encoder (instead of the number of bytes).
803
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000804- Issue #2422: When compiled with the ``--with-valgrind`` option, the
805 pymalloc allocator will be automatically disabled when running under
806 Valgrind. This gives improved memory leak detection when running
807 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +0000876- Issue #6816: runpy now provides a run_path function that allows Python code
877 to execute file paths that refer to source or compiled Python files as well
878 as zipfiles, directories and other valid sys.path entries that contain a

1990 result in struct.error. Previously an x with an __int__ method
1991 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1992 ,'*i', '*l', and an x with a __long__ method could be packed by
1993 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1994 TypeError used to be raised (with a confusing error message) for
1995 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002189- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2190 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2191 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2192 ``printf`` function, whereas PyString_FromFormat has an independent
2193 implementation and uses "%zd" on all platforms for size_t values.
2194 This makes a difference on win64, where ``printf`` needs "%Id" to display
2195 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00002215 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

2218 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2219 type object.

2290 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2291 for catch_warnings() also led to an improvement in the raising of a
2292 DeprecationWarning related to warnings.warn_explicit().
2293

2316
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002317- Issue #2975: When compiling several extension modules with Visual Studio 2008
2318 from the same python interpreter, some environment variables would grow
2319 without limit.
2320
Benjamin Peterson37346b22008-08-23 20:27:43 +00002321- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002358What's New in Python 2.6 beta 3?
2359================================
2360
Barry Warsaw07a4a382008-08-21 01:15:08 +00002361*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002362
2363Core and Builtins
2364-----------------
2365
Guido van Rossumf8402962008-08-20 15:01:50 +00002366- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2367 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2368 extensions do not automatically benefit from the class attribute
2369 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2370 to their tp_flags field if they care. This is a backwards
2371 compatibility feature; in 3.0, all types will use the cache by
2372 default.
2373
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002374- Keyword arguments can now follow starred arguments. (``f(a, *args,
2375 keyword=23)`` is now valid syntax.)
2376
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002377- ctypes function pointers that are COM methods have a boolean True
2378 value again.
2379
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002380- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2381 by denying s# to parse objects that have a releasebuffer procedure,
2382 and introducing s*.
2383
Georg Brandl1e13ea92008-08-11 09:07:59 +00002384- Issue #3537: Fix an assertion failure when an empty but presized dict
2385 object was stored in the freelist.
2386
Mark Dickinsonb6467572008-08-04 21:30:09 +00002387- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2388 ValueError consistently across platforms.
2389
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002390- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2391 (64bit Unix, for example), unichr() would truncate its argument and return
2392 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2393
Neal Norwitze7d8be82008-07-31 17:17:14 +00002394- Apply security patches from Apple.
2395
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002396- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2397 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2398
Antoine Pitrou92f82162008-07-25 22:22:08 +00002399- Issue #1819: function calls with several named parameters are now on
2400 average 35% faster (as measured by pybench).
2401
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002402- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2403 the python debugger steps into a class statement: the free variables (local
2404 variables defined in an outer scope) would be deleted from the outer scope.
2405
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002406- Issue #2620: Overflow checking when allocating or reallocating memory
2407 was not always being done properly in some python types and extension
2408 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2409 all been updated to perform better checks and places in the code that
2410 would previously leak memory on the error path when such an allocation
2411 failed have been fixed.
2412
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002413Library
2414-------
2415

2417
Benjamin Petersone977ad42008-08-20 01:42:01 +00002418- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2419 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2420
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002421- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2422 version reported by these tools does not necessarily follow the python
2423 version numbering scheme, so the module is less strict when parsing it.
2424
Nick Coghlanf70385a2008-08-18 12:42:46 +00002425- Issue #2235: Added Py3k warnings for types which will become unhashable
2426 under the stricter __hash__ inheritance rules in 3.0. Several types
2427 which did not meet the rules for hash invariants and were already
2428 unhashable in 3.0 have now been explicitly flagged as unhashable in
2429 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2430 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2431
Brett Cannon88f801d2008-08-18 00:46:22 +00002432- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2436
Brett Cannon46225e72008-08-18 00:36:52 +00002437- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2440
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002441- Issue #3575: Incremental decoder's decode function now takes bytearray
2442 by using 's*' instead of 't#'.
2443
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002444- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002445 fails unicode conversion on 2nd parameter. (windows only)
2446
Facundo Batista94f243a2008-08-17 03:38:39 +00002447- Issue 2464. urllib2 now supports a malformation in the URL received
2448 in a redirect.
2449
Brett Cannonabe423e2008-08-16 21:47:07 +00002450- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002451 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002452
Facundo Batistaeb90b782008-08-16 14:44:07 +00002453- Issue #2776: fixed small issue when handling an URL with double slash
2454 after a 302 response in the case of not going through a proxy.
2455
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002456- Issue #2676: in the email package, content-type parsing was hanging on
2457 pathological input because of quadratic or exponential behaviour of a
2458 regular expression.
2459
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002460- Issue #3476: binary buffered reading through the new "io" library is now
2461 thread-safe.
2462
Brett Cannonbf3157b2008-08-14 05:00:03 +00002463- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2464 since mimetools itself is deprecated. Because modules are cached, all
2465 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2466
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002467- Issue #3134: shutil referenced undefined WindowsError symbol.
2468
Robert Schuppenies14646332008-08-10 11:01:53 +00002469- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2470 menu entries were not deleted.
2471
Brett Cannon83e81842008-08-09 23:30:55 +00002472- Copied the implementation of reduce() to _functools.reduce() to have a
2473 version that did not raise a DeprecationWarning under -3.
2474
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002475- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2476 a MemoryError rather than silently stop the iteration.
2477
Guido van Rossum59ce9012008-08-09 14:55:34 +00002478- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2479 to _sre.compile() will now be rejected. This should not affect anybody
2480 since the re.compile() function never generates invalid re-bytecode.
2481
Skip Montanaroa032bf42008-08-08 22:52:51 +00002482- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Brett Cannon3aa2a492008-08-06 22:28:09 +00002486- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2487 the reload() built-in has been removed.
2488
Brett Cannon7e30b672008-08-04 21:52:25 +00002489- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002490 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002501 asking for a specific length. This problem only affected files opened
2502 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002503

2529 mode 0600 rather than 000 under Unix.
2530
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002531- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2561 its methods now allow for items objects that can be converted to
2562 an integer using operator.index().
2563
Mark Dickinson64b7e502008-07-16 09:40:03 +00002564- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2565 produced a ValueError instead of giving the correct float.
2566
Eric Smitha5fa5a22008-07-16 00:11:49 +00002567- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2568 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2569
Mark Dickinson7103aa42008-07-15 19:08:33 +00002570- Issue #3008: the float type has a new instance method 'float.hex'

Nick Coghlan6d6bd442008-07-15 15:40:22 +00002574- Issue #2235: __hash__ is once again inherited by default. To allow
2575 collections.Hashable to remain meaningful in the presence of the
2576 default hash implementation (object.__hash__), it is now possible
2577 to explicit block inheritance of hash by setting __hash__=None at
2578 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2579 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00002581- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2582 the parent module cannot be found while performing an absolute import.
2583 This means that an incorrectly defined __package__ attribute will
2584 now only prevent relative imports in that module rather than causing
2585 all imports from that module to fail.
2586
Nick Coghlan14ff9942008-07-08 14:21:42 +00002587- Issue #2517: Allow unicode messages in Exceptions again by correctly

2598
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002599- Issue #3004: Minor change to slice.indices(): the start and stop
2600 arguments are now treated identically, making the behaviour easier
2601 to describe and understand. For example, slice(None, -10,
2602 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2603 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2604 10, -1).

2647 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002648 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00003058 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003059

3107 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003120- Issue #1631171: Re-implement the 'warnings' module in C (the
3121 original Python code has been kept as backup). This will allow for
3122 using the 'warning's machinery in such places as the parser where
3123 use of pure Python code is not possible. Both the ``showarning()``
3124 and ``formatwarning()`` gain an optional 'line' argument which is
3125 not called by default for backwards-compatibility reasons. Setting
3126 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00003190- Issue #2550: The approach used by client/server code for obtaining
3191 ports to listen on in network-oriented tests has been refined in an
3192 effort to facilitate running multiple instances of the entire
3193 regression test suite in parallel without issue.
3194 test_support.bind_port() has been fixed such that it will always
3195 return a unique port -- which wasn't always the case with the
3196 previous implementation, especially if socket options had been set
3197 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3198 new implementation of bind_port() will actually raise an exception
3199 if it is passed an AF_INET/SOCK_STREAM socket with either the
3200 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3201 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3202 the socket it's been passed. This currently only applies to
3203 Windows. This option prevents any other sockets from binding to the
3204 host/port we've bound to, thus removing the possibility of the
3205 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3206 when a second SOCK_STREAM socket binds and accepts to a host/port
3207 that's already been bound by another socket. The optional preferred
3208 port parameter to bind_port() has been removed. Under no
3209 circumstances should tests be hard coding ports!
3210
3211 test_support.find_unused_port() has also been introduced, which will
3212 pass a temporary socket object to bind_port() in order to obtain an
3213 unused port. The temporary socket object is then closed and
3214 deleted, and the port is returned. This method should only be used
3215 for obtaining an unused port in order to pass to an external program
3216 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3217 a parameter to a server-oriented class that doesn't give you direct
3218 access to the underlying socket used.
3219
3220 Finally, test_support.HOST has been introduced, which should be used
3221 for the host argument of any relevant socket calls (i.e. bind and
3222 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003223
3224 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003225 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003226 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3227 test_asynchat and test_socket_ssl.
3228
Georg Brandl3ee81df2008-05-17 18:14:43 +00003229 It is now possible for multiple instances of the regression test
3230 suite to run in parallel without issue.

3498
Fred Drakea8ee94b2008-03-01 02:45:07 +00003499- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003500 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003501
Georg Brandlad61bc82008-02-23 15:11:18 +00003502- Issue #2067: file.__exit__() now calls subclasses' close() method.
3503
3504- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003505
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003506- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003507 issue 215555 for a discussion.
3508
Eric Smitha73fbe72008-02-23 03:09:44 +00003509- Added the future_builtins module, which contains hex() and oct().
3510 These are the PEP 3127 version of these functions, designed to be
3511 compatible with the hex() and oct() builtins from Python 3.0. They
3512 differ slightly in their output formats from the existing, unchanged
3513 Python 2.6 builtins. The expected usage of the future_builtins
3514 module is:
3515 from future_builtins import hex, oct
3516
Eric Smith7ef40bf2008-02-20 23:34:22 +00003517- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3518 exponents for exponents with absolute value < 100. Follows C99
3519 standard. This is a change on Windows, which would use 3 digits.
3520 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3521 so that any alterations it does to the resulting string will be
3522 available in stringlib/formatter.h (for float.__format__).
3523
Eric Smith5a3c1352008-02-19 13:21:56 +00003524- Implemented PEP 3101, Advanced String Formatting. This adds a new
3525 builtin format(); a format() method for str and unicode; a
3526 __format__() method to object, str, unicode, int, long, float, and
3527 datetime; the class string.Formatter; and the C API
3528 PyObject_Format().
3529
Georg Brandl3ee81df2008-05-17 18:14:43 +00003530- Fixed several potential crashes, all caused by specially crafted
3531 __del__ methods exploiting objects in temporarily inconsistent
3532 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003533
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003534- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535 prevent a possible crash: an Abstract Base Class would try to access
3536 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003537
Georg Brandl3ee81df2008-05-17 18:14:43 +00003538- Fixed repr() and str() of complex numbers with infinity or nan as
3539 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003541- Clear all free lists during a gc.collect() of the highest generation
3542 in order to allow pymalloc to free more arenas. Python may give back
3543 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003544
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545- Issue #2045: Fix an infinite recursion triggered when printing a
3546 subclass of collections.defaultdict, if its default_factory is set
3547 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003548
Christian Heimesf75dbef2008-02-08 00:11:31 +00003549- Fixed a minor memory leak in dictobject.c. The content of the free
3550 list was not freed on interpreter shutdown.
3551
Georg Brandl3ee81df2008-05-17 18:14:43 +00003552- Limit free list of method and builtin function objects to 256
3553 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003554
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3556 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003557 to compact the internal free lists of pre-allocted ints and floats.
3558
Georg Brandl3ee81df2008-05-17 18:14:43 +00003559- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3560 calls. Python expected the return type int but the fork familie
3561 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003562
Georg Brandl3ee81df2008-05-17 18:14:43 +00003563- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3564 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003565
Georg Brandl3ee81df2008-05-17 18:14:43 +00003566- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3567 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3573 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003574
Georg Brandl3ee81df2008-05-17 18:14:43 +00003575- Patch #1473257: generator objects gain a gi_code attribute. This is
3576 the same object as the func_code attribute of the function that
3577 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003578
Georg Brandl3ee81df2008-05-17 18:14:43 +00003579- Issue #1920: "while 0" statements were completely removed by the
3580 compiler, even in the presence of an "else" clause, which is
3581 supposed to be run when the condition is false. Now the compiler
3582 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003583
Guido van Rossumeead05f2008-01-24 18:21:02 +00003584- A few crashers fixed: weakref_in_del.py (issue #1377858);
3585 loosing_dict_ref.py (issue #1303614, test67.py);
3586 borrowed_ref_[34].py (not in tracker).
3587
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003588- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003589 suppressed while an extension is loaded by calling SetErrorMode in
3590 dynload_win.c. The error is still reported properly.
3591
Georg Brandl3ee81df2008-05-17 18:14:43 +00003592- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003593 several extension methods and modules do not work without unicode
3594 support.
3595
Georg Brandl26543b12008-01-21 18:36:51 +00003596- Issue #1882: when compiling code from a string, encoding cookies in the
3597 second line of code were not always recognized correctly.
3598
Georg Brandl14404b62008-01-19 19:27:05 +00003599- Issue #1679: "0x" was taken as a valid integer literal.
3600
Georg Brandl6caad7d2008-01-26 14:19:22 +00003601- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003602 added.
3603
Christian Heimesc94e2b52008-01-14 04:13:37 +00003604- sys.float_info / PyFloat_GetInfo: The floating point information
3605 object was converted from a dict to a specialized structseq object.
3606
Georg Brandl3ee81df2008-05-17 18:14:43 +00003607- Patch #1816: Added sys.flags structseq. It exposes the status of
3608 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003609
Georg Brandl3ee81df2008-05-17 18:14:43 +00003610- Objects/structseq.c: Implemented new structseq representation. The
3611 patch makes structseqs (e.g. the return value of os.stat) more
3612 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003613
Georg Brandl3ee81df2008-05-17 18:14:43 +00003614- Patch #1700288: added a type attribute cache that caches method
3615 accesses, resulting in speedups in heavily object-oriented code.

3623 envvar and sys.dont_write_bytecode attribute. All these can be set
3624 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003625
Georg Brandl3ee81df2008-05-17 18:14:43 +00003626- Improve some exception messages when Windows fails to load an
3627 extension module. Now we get for example '%1 is not a valid Win32
3628 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003629

3633 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003634
Christian Heimes0a8143f2007-12-18 23:22:54 +00003635- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003636 and INF. float("nan"), float("inf") and float("-inf") now work on
3637 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003638
Georg Brandl3ee81df2008-05-17 18:14:43 +00003639- Compiler now generates simpler and faster code for dictionary
3640 literals. The oparg for BUILD_MAP now indicates an estimated
3641 dictionary size. There is a new opcode, STORE_MAP, for adding
3642 entries to the dictionary.

3685
Georg Brandl3ee81df2008-05-17 18:14:43 +00003686- The enumerate() builtin function is no longer bounded to sequences
3687 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3688 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003689
Georg Brandl3ee81df2008-05-17 18:14:43 +00003690- Issue #1686386: Tuple's tp_repr did not take into account the
3691 possibility of having a self-referential tuple, which is possible
3692 from C code. Nor did object's tp_str consider that a type's tp_str
3693 could do something that could lead to an inifinite recursion.
3694 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3695 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003697- Issue #1164: It was possible to trigger deadlock when using the
3698 'print' statement to write to a file since the GIL was not released
3699 as needed. Now PyObject_Print() does the right thing along with
3700 various tp_print implementations of the built-in types and those in
3701 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00003710- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003711 PyObject_Call() never calling back out to Python code to trigger
3712 recursion depth updates/checks. Required the creation of a static

Georg Brandl3ee81df2008-05-17 18:14:43 +00003731 __*__ attributes. (Some already existed, e.g., __doc__ and
3732 __name__.)

3739
Collin Winter62903052007-05-18 23:11:24 +00003740- except clauses may now be spelled either "except E, target:" or

3742 with Python 3.0.

3748
Vinay Sajip8549ce32007-05-06 17:53:37 +00003749- When __slots__ are set to a unicode string, make it work the same as

3762
Guido van Rossum143b5642007-03-23 04:58:42 +00003763- Bug #1683368: The object.__init__() and object.__new__() methods are
3764 now stricter in rejecting excess arguments. The only time when
3765 either allows excess arguments is when it is not overridden and the
3766 other one is. For backwards compatibility, when both are
3767 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003768 warning later). Also, type.__init__() insists on the same signature
3769 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003771- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3772 object to complex using its __complex__() method before falling back
3773 to the __float__() method. Therefore, the functions in the cmath
3774 module now can operate on objects that define a __complex__()
3775 method.

3792
Georg Brandl7b9c5552007-03-12 14:30:05 +00003793- Bug #1678647: write a newline after printing an exception in any
3794 case, even when converting the value to a string failed.
3795
Georg Brandl871f1bc2007-03-12 13:17:36 +00003796- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003797 its argument, if it exists. If not, it will work like before. This
3798 allows customizing the output of dir() in the presence of a
3799 __getattr__().

3808 parthensized forms. This means complex(repr(x)) now works instead of
3809 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003810
Georg Brandlaa2321b2007-03-07 00:40:28 +00003811- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812 makes the filenames the warning module prints much more sensible
3813 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003826- Patch #1674228: when assigning a slice (old-style), check for the
3827 sq_ass_slice instead of the sq_slice slot.
3828
Georg Brandl3ee81df2008-05-17 18:14:43 +00003829- When printing an unraisable error, don't print exceptions. before

4397
Georg Brandl92a6bae2007-03-13 17:43:32 +00004398- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004399 are set for invalid interpolation sequences that would lead to

4456 TestCase and TestSuite subclasses (not instances) are no longer
4457 accepted in TestSuite.addTest(). This should cause no
4458 incompatibility since it never made sense with ordinary subclasses

4743 obtained from the TLS negotiation itself. Patch contributed by Bill
4744 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004745
Georg Brandl3ee81df2008-05-17 18:14:43 +00004746- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004747 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004749 does not claim to support starttls. Adds the
4750 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004849 time so that opening a database previously created with the DB_DUP
4850 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4851 opens. Specifically: dictionary assignment to a DB object will
4852 replace all values for a given key when the database allows
4853 duplicate values. DB users should use DB.put(k, v) when they want
4854 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004855

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005133- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005134 periodic threadstate and signal checking in tight loops. By
5135 default, this option is turned-off. It should only be enabled in
5136 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005137

5187-----
5188
Georg Brandl3ee81df2008-05-17 18:14:43 +00005189- Unified naming convention for free lists and their limits. All free
5190 lists in Object/ are named ``free_list``, the counter ``numfree``
5191 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5192 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005193
Georg Brandl3ee81df2008-05-17 18:14:43 +00005194- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5195 to ``PyTuple_SetItem``, it can be used to populate a brand new
5196 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005197

5205
5206- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5207 ``PyFloat_GetInfo()`` to the float API.
5208
Georg Brandl3ee81df2008-05-17 18:14:43 +00005209- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5210 of w# format code incorrectly truncated the length to an int, even
5211 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5212 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005213
Georg Brandl3ee81df2008-05-17 18:14:43 +00005214- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5232- Fix some leftovers from the conversion from int to Py_ssize_t
5233 (relevant to strings and sequences of more than 2**31 items).
5234
5235- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5236 outside of pystate.c and should not be necessary.
5237
Georg Brandl3ee81df2008-05-17 18:14:43 +00005238- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5239 absolute imports. In earlier versions they might have used relative
5240 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005241
Georg Brandl3ee81df2008-05-17 18:14:43 +00005242- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5243 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005244
Georg Brandl3ee81df2008-05-17 18:14:43 +00005245- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005270- Removed the macfs module. It had been deprecated since Python 2.5.
5271 This lead to the deprecation of macostools.touched() as it relied
5272 solely on macfs and was a no-op under OS X.
