12Core and Builtins
13-----------------
14
Victor Stinnerb4b0a292010-01-31 22:32:15 +000015- Issue #7819: Check sys.call_tracing() arguments types.
16
Mark Dickinson36ecd672010-01-29 17:11:39 +000017- Issue #7788: Fix an interpreter crash produced by deleting a list
18 slice with very large step value.
19
Eric Smithee931b72010-01-27 00:28:29 +000020- Issue #7766: Change sys.getwindowsversion() return value to a named
21 tuple and add the additional members returned in an OSVERSIONINFOEX
22 structure. The new members are service_pack_major, service_pack_minor,
23 suite_mask, and product_type.
24
Antoine Pitroue80a6a42010-01-17 12:26:20 +000025- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
26 could crash in many places because of the PyByteArray_AS_STRING() macro
27 returning NULL. The macro now returns a statically allocated empty
28 string instead.
29
Antoine Pitrou64672132010-01-13 07:55:48 +000030- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
31 methods of bytes, bytearray and unicode objects by using a common
32 implementation based on stringlib's fast search. Patch by Florent Xicluna.
33
Mark Dickinson476279f2010-01-16 10:44:00 +000034- Issue #7632: Fix various str -> float conversion bugs present in 2.7
35 alpha 2, including: (1) a serious 'wrong output' bug that could
36 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
37 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000038 strings corresponding to subnormal values, (3) a memory leak for
39 some values large enough to cause overflow, and (4) a number of
40 flaws that could lead to incorrectly rounded results.
Mark Dickinson8efef5c2010-01-12 22:23:56 +000041
Brett Cannon3ffa43d2010-01-14 20:00:28 +000042- Issue #7319, #7770: Silence DeprecationWarning by default when -3 is not
43 used.

54
Antoine Pitrouf3fa0742010-01-31 22:26:04 +000055- Issue #6939: Fix file I/O objects in the `io` module to keep the original
56 file position when calling `truncate()`. It would previously change the
57 file position to the given argument, which goes against the tradition of
58 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
59
Benjamin Petersone06f7112010-01-28 02:15:02 +000060- UserDict is now a new-style class.
61
Antoine Pitrou94c33eb2010-01-27 20:59:50 +000062- Issue #7610: Reworked implementation of the internal
63 :class:`zipfile.ZipExtFile` class used to represent files stored inside
64 an archive. The new implementation is significantly faster and can
65 be wrapped in a :class:`io.BufferedReader` object for more speedups.
66 It also solves an issue where interleaved calls to `read()` and
67 `readline()` give wrong results. Patch by Nir Aides.
68

74 the release file is empty.
75
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +000076- Issue #7748: Since unicode values are supported for some metadata options
77 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
78 encoded string for them. This ensure that the upload and register commands
79 send the right values to PyPI without any error.
80
R. David Murrayed44dfa2010-01-16 05:15:17 +000081- Issue #1670765: Prevent email.generator.Generator from re-wrapping

Tarek Ziadédc0f4872010-01-11 22:50:29 +0000101- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since
102 Extension extra options may change the output without changing the .c
103 file). Initial patch by Collin Winter.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000140What's New in Python 2.7 alpha 2?
141=================================
142
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000143*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000144
145Core and Builtins
146-----------------
147
Benjamin Petersonecdae192010-01-04 00:43:01 +0000148- The __complex__ method is now looked up on the class of instances to make it
149 consistent with other special methods.
150
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000151- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
152 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
153
Mark Dickinson1b34d252010-01-01 17:27:30 +0000154- Issue #5080: A number of functions and methods previously produced a
155 DeprecationWarning when passed a float argument where an integer was
156 expected. These functions and methods now raise TypeError instead.
157 The majority of the effects of this change are in the extension
158 modules, but some core functions and methods are affected: notably
159 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
160 methods.
161
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000162- Issue #7604: Deleting an unset slotted attribute did not raise an
163 AttributeError.

170
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000171- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
172 used to drop the time part of the result.
173
Mark Dickinson46572832009-12-27 14:55:57 +0000174- Issue #1811: improve accuracy and cross-platform consistency for
175 true division of integers: the result of a/b is now correctly
176 rounded for ints a and b (at least on IEEE 754 platforms), and in
177 particular does not depend on the internal representation of a long.
178
Ezio Melottif84caf42009-12-24 22:25:17 +0000179- Issue #6108: unicode(exception) and str(exception) should return the same
180 message when only __str__ (and not __unicode__) is overridden in the subclass.
181
Ronald Oussoren92919a62009-12-24 13:30:58 +0000182- Issue #6834: replace the implementation for the 'python' and 'pythonw'
183 executables on OSX.
184
185 These executables now work properly with the arch(1) command:
186 ``arch -ppc python`` will start a universal binary version of python
187 in PPC mode (unlike previous releases).
188
R. David Murray0a0a1a82009-12-14 16:28:26 +0000189- Issue #1680159: unicode coercion during an 'in' operation no longer masks
190 the underlying error when the coercion fails for the left hand operand.
191
Benjamin Peterson4895af42009-12-13 16:36:53 +0000192- Issue #7491: Metaclass's __cmp__ method was ignored.
193
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000194- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +0000195 in the middle of populating a tuple. Patch by Florent Xicluna.

208 by Arfrever.
209
Antoine Pitrou80157252010-01-08 19:20:17 +0000210- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
211 renaming of `cPickle` to `pickle`. The warning was annoying since there's
212 no alternative to cPickle if you care about performance. Patch by Florent
213 Xicluna.
214

240 the Distutils upload command to avoid an error when PyPI reads it.
241 This occurs on long passwords. Initial patch by JP St. Pierre.
242
243- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000244 Patch by Tatsuhiro Tsujikawa.
245
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000246- Issue #7349: Make methods of file objects in the io module accept None as an
247 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
248 the same as passing no argument.
249
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000250- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000324- Issue #7419: setlocale() could crash the interpreter on Windows when called
325 with invalid values.
326
Eric Smithc4ab8332009-11-29 17:40:57 +0000327- Issue #3382: 'F' formatting for float and complex now convert the
328 result to upper case. This only affects 'inf' and 'nan', since 'f'
329 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000330
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000331- Remove switch from "%f" formatting to "%g" formatting for floats
332 larger than 1e50 in absolute value.
333
Mark Dickinson18cfada2009-11-23 18:46:41 +0000334- Remove restrictions on precision when formatting floats. E.g.,
335 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
336 requested 120 significant digits instead.
337
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000338- Add Py3k warnings for parameter names in parenthesis.
339

Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000341
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000342- Issue #7085: Fix crash when importing some extensions in a thread
343 on MacOSX 10.6.
344
Mark Dickinsonb678de82009-11-19 18:41:49 +0000345- Issue #7117: repr(x) for a float x returns a result based on the
346 shortest decimal string that's guaranteed to round back to x under
347 correct rounding (with round-half-to-even rounding mode).
348 Previously it gave a string based on rounding x to 17 decimal digits.
349 repr(x) for a complex number behaves similarly. On platforms where
350 the correctly-rounded strtod and dtoa code is not supported (see below),
351 repr is unchanged.
352
353- Issue #7117: On almost all platforms: float-to-string and
354 string-to-float conversions within Python are now correctly rounded.
355 Places these conversions occur include: str for floats and complex
356 numbers; the float and complex constructors; old-style and new-style
357 numeric formatting; serialization and deserialization of floats and
358 complex numbers using marshal, pickle and json; parsing of float and
359 imaginary literals in Python code; Decimal-to-float conversion.
360
361 The conversions use a Python-adapted version of David Gay's
362 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
363 functions. This code is supported on Windows, and on Unix-like
364 platforms using gcc, icc or suncc as the C compiler. There may be a
365 small number of platforms on which correct operation of this code
366 cannot be guaranteed, so the code is not used: notably, this applies
367 to platforms where the C double format is not IEEE 754 binary64, and
368 to platforms on x86 hardware where the x87 FPU is set to 64-bit
369 precision and Python's configure script is unable to determine how
370 to change the FPU precision. On these platforms conversions use the
371 platform strtod and dtoa, as before.
372
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000373- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000374 now uses the correctly-rounded string <-> float conversions
375 described above (when available), and so produces correctly rounded
376 results that will display nicely under the float repr. There are
377 two related small changes: (1) round now accepts any class with an
378 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000379 floats for the second argument), and (2) an excessively large second
380 integer argument (e.g., round(1.234, 10**100)) no longer raises an
381 exception.
382
Philip Jenveyfab8be22009-11-17 02:42:26 +0000383- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
384

510 statement and correctly lookup the __enter__ and __exit__ special methods.
511
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000512- Issue #5829: complex("1e500") no longer raises OverflowError. This
513 makes it consistent with float("1e500") and interpretation of real

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000523- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
524 (1) inf and nan strings with trailing whitespace were incorrectly
525 rejected; (2) parsing of strings representing infinities and nans
526 was locale aware; and (3) the interpretation of fromhex('-nan')
527 didn't match that of float('-nan').
528
Eric Smitha985a3a2009-05-05 18:26:08 +0000529- Issue #5920: For float.__format__, change the behavior with the
530 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
531 to be like 'g' but with at least one decimal point and with a
532 default precision of 12. Previously, the behavior the same but with
533 a default precision of 6. This more closely matches str(), and
534 reduces surprises when adding alignment flags to the empty
535 presentation type. This also affects the new complex.__format__ in
536 the same way.
537
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000538- Issue #5890: in subclasses of 'property' the __doc__ attribute was

Mark Dickinsonefc82f72009-03-20 15:51:55 +0000609- Issue #4258: Make it possible to use base 2**30 instead of base
610 2**15 for the internal representation of integers, for performance
611 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
612 --enable-big-digits option to configure, which overrides the
613 default. Add sys.long_info structseq to provide information about
614 the internal format.
615
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000616- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

618
Mark Dickinson6b265f12009-03-18 16:07:26 +0000619- Issue #4474: PyUnicode_FromWideChar now converts characters outside
620 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
621 and sizeof(Py_UNICODE) == 2.
622
Eric Smith6f42edb2009-03-14 11:57:26 +0000623- Issue #5237: Allow auto-numbered fields in str.format(). For
624 example: '{} {}'.format(1, 2) == '1 2'.
625
Brett Cannon6c4cff02009-03-11 04:51:06 +0000626- Issue #3652: Make the 'line' argument for warnings.showwarning() a

628
Eric Smithe9fb6862009-02-20 14:02:36 +0000629- Issue #5247: Improve error message when unknown format codes are

631 float arguments.
632
Raymond Hettinger08259e82009-02-18 23:10:19 +0000633- Running Python with the -3 option now also warns about classic division
634 for ints and longs.
635
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000636- Issue #5260: Long integers now consume less memory: average
637 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
638 on a 64-bit system.
639
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000640- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

645
Benjamin Petersone18ef192009-01-20 14:21:16 +0000646- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
647
Georg Brandl29c6a282009-04-05 20:23:13 +0000648- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000649 were suppressing all exceptions. These include list(), filter(), map(),
650 zip(), and bytearray().
651
Benjamin Peterson596d3062009-01-19 15:42:23 +0000652- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
653 functions.
654
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000655- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

659
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000660- Issue #4935: The overflow checking code in the expandtabs() method common
661 to str, bytes and bytearray could be optimized away by the compiler, letting
662 the interpreter segfault instead of raising an error.
663
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000664- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000671- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
672 collecting the oldest generation) so that allocating lots of objects without
673 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000674 Martin von Löwis at

678
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000679- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
680 an existing .py counterpart, override the co_filename attributes of all
681 code objects if the original filename is obsolete (which can happen if the
682 file has been renamed, moved, or if it is accessed through different paths).
683 Patch by Ziga Seilnacht and Jean-Paul Calderone.
684
Martin v. Löwis5344c992009-01-02 20:32:55 +0000685- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000687- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
688 file with `str' filename on Windows.
689
Antoine Pitrouaa687902009-01-01 14:11:22 +0000690- Issue #3680: Reference cycles created through a dict, set or deque iterator
691 did not get collected.
692
Nick Coghlan180e4002008-12-30 01:18:48 +0000693- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
694 where the tp_hash and tp_dict slots are both NULL.
695
Benjamin Peterson7af65562008-12-29 17:56:58 +0000696- Issue #4764: With io.open, IOError.filename is set when trying to open a

703 bytearray.translate(). It was always allowed for bytes.translate().
704
Skip Montanarof205c132008-12-23 03:30:15 +0000705- Added test case to ensure attempts to read from a file opened for writing
706 fail.
707
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000708- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

719
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000720- Issue #4597: Fixed several opcodes that weren't always propagating
721 exceptions.
722
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000723- Issue #4445: Replace "sizeof(PyStringObject)" with
724 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
725 str instances. On a typical machine this saves 3 bytes of memory
726 (on average) per string allocation.
727
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000728- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
729 interpreter to abort ("Fatal Python error: Could not reset the stack!")
730 instead of throwing a MemoryError.
731
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000732- Issue #3689: The list reversed iterator now supports __length_hint__
733 instead of __len__. Behavior now matches other reversed iterators.
734
Benjamin Petersonc078f922008-11-21 22:27:24 +0000735- Issue #4367: Python would segfault during compiling when the unicodedata
736 module couldn't be imported and \N escapes were present.
737
Vinay Sajip213faca2008-12-03 23:22:58 +0000738- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000739 method on file objects with closefd=False. The file descriptor is still
740 kept open but the file object behaves like a closed file. The ``FileIO``
741 object also got a new readonly attribute ``closefd``.
742
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000743- Issue #4348: Some bytearray methods returned that didn't cause any change to
744 the bytearray, returned the same bytearray instead of a copy.
745
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000746- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
747

751
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000752- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

754
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000755- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
756 method does not return iterators for the 4th and 5th items.
757
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000758- Issue #4209: Enabling unicode_literals and the print_function in the same
759 __future__ import didn't work.
760
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000761- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000762 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000763
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000764- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
765 returned a path longer than MAX_PATH. (But It's doubtful this code path is
766 really executed because I cannot move to such directory on win2k)
767
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000768- Issue #4069: When set.remove(element) is used with a set element, the element
769 is temporarily replaced with an equivalent frozenset. But the eventual
770 KeyError would always report the empty frozenset([]) as the missing key. Now
771 it correctly refers to the initial element.
772
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000773- Issue #4509: Various issues surrounding resize of bytearray objects to
774 which there are buffer exports.
775
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000776- Issue #4748: Lambda generators no longer return a value.

784
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000785- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000788- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
789 returned them on 64bit platforms.
790
Walter Dörwalded960ac2009-05-03 22:36:33 +0000791- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
792 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
793 step. This avoids problems with counting UTF-8 bytes that ignores the effect
794 of using the replace error handler in PyUnicode_DecodeUTF8().
795
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000796- Issue #3739: The unicode-internal encoder now reports the number of characters
797 consumed like any other encoder (instead of the number of bytes).
798
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000799- Issue #2422: When compiled with the ``--with-valgrind`` option, the
800 pymalloc allocator will be automatically disabled when running under
801 Valgrind. This gives improved memory leak detection when running
802 under Valgrind, while taking advantage of pymalloc at other times.

1985 result in struct.error. Previously an x with an __int__ method
1986 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1987 ,'*i', '*l', and an x with a __long__ method could be packed by
1988 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1989 TypeError used to be raised (with a confusing error message) for
1990 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

2183
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002184- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2185 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2186 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2187 ``printf`` function, whereas PyString_FromFormat has an independent
2188 implementation and uses "%zd" on all platforms for size_t values.
2189 This makes a difference on win64, where ``printf`` needs "%Id" to display
2190 64bit values.

2196 object; previously an int would be returned for small values. the __long__

2208
Vinay Sajip35e3b032008-09-01 14:33:59 +00002209- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002210 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2211 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2212 when given a tuple of classes as second argument, were looking up
2213 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2214 type object.
2215

2285 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2286 for catch_warnings() also led to an improvement in the raising of a
2287 DeprecationWarning related to warnings.warn_explicit().
2288

2311
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002312- Issue #2975: When compiling several extension modules with Visual Studio 2008
2313 from the same python interpreter, some environment variables would grow
2314 without limit.
2315
Benjamin Peterson37346b22008-08-23 20:27:43 +00002316- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002353What's New in Python 2.6 beta 3?
2354================================
2355
Barry Warsaw07a4a382008-08-21 01:15:08 +00002356*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002357
2358Core and Builtins
2359-----------------
2360
Guido van Rossumf8402962008-08-20 15:01:50 +00002361- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2362 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2363 extensions do not automatically benefit from the class attribute
2364 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2365 to their tp_flags field if they care. This is a backwards
2366 compatibility feature; in 3.0, all types will use the cache by
2367 default.
2368
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002369- Keyword arguments can now follow starred arguments. (``f(a, *args,
2370 keyword=23)`` is now valid syntax.)
2371
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002372- ctypes function pointers that are COM methods have a boolean True
2373 value again.
2374
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002375- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2376 by denying s# to parse objects that have a releasebuffer procedure,
2377 and introducing s*.
2378
Georg Brandl1e13ea92008-08-11 09:07:59 +00002379- Issue #3537: Fix an assertion failure when an empty but presized dict
2380 object was stored in the freelist.
2381
Mark Dickinsonb6467572008-08-04 21:30:09 +00002382- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2383 ValueError consistently across platforms.
2384
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002385- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2386 (64bit Unix, for example), unichr() would truncate its argument and return
2387 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2388
Neal Norwitze7d8be82008-07-31 17:17:14 +00002389- Apply security patches from Apple.
2390
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002391- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2392 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2393
Antoine Pitrou92f82162008-07-25 22:22:08 +00002394- Issue #1819: function calls with several named parameters are now on
2395 average 35% faster (as measured by pybench).
2396
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002397- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2398 the python debugger steps into a class statement: the free variables (local
2399 variables defined in an outer scope) would be deleted from the outer scope.
2400
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002401- Issue #2620: Overflow checking when allocating or reallocating memory
2402 was not always being done properly in some python types and extension
2403 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2404 all been updated to perform better checks and places in the code that
2405 would previously leak memory on the error path when such an allocation
2406 failed have been fixed.
2407
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002408Library
2409-------
2410

2412
Benjamin Petersone977ad42008-08-20 01:42:01 +00002413- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2414 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2415
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002416- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2417 version reported by these tools does not necessarily follow the python
2418 version numbering scheme, so the module is less strict when parsing it.
2419
Nick Coghlanf70385a2008-08-18 12:42:46 +00002420- Issue #2235: Added Py3k warnings for types which will become unhashable
2421 under the stricter __hash__ inheritance rules in 3.0. Several types
2422 which did not meet the rules for hash invariants and were already
2423 unhashable in 3.0 have now been explicitly flagged as unhashable in
2424 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2425 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2426
Brett Cannon88f801d2008-08-18 00:46:22 +00002427- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2431
Brett Cannon46225e72008-08-18 00:36:52 +00002432- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2435
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002436- Issue #3575: Incremental decoder's decode function now takes bytearray
2437 by using 's*' instead of 't#'.
2438
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002439- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002440 fails unicode conversion on 2nd parameter. (windows only)
2441
Facundo Batista94f243a2008-08-17 03:38:39 +00002442- Issue 2464. urllib2 now supports a malformation in the URL received
2443 in a redirect.
2444
Brett Cannonabe423e2008-08-16 21:47:07 +00002445- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002446 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002447
Facundo Batistaeb90b782008-08-16 14:44:07 +00002448- Issue #2776: fixed small issue when handling an URL with double slash
2449 after a 302 response in the case of not going through a proxy.
2450
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002451- Issue #2676: in the email package, content-type parsing was hanging on
2452 pathological input because of quadratic or exponential behaviour of a
2453 regular expression.
2454
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002455- Issue #3476: binary buffered reading through the new "io" library is now
2456 thread-safe.
2457
Brett Cannonbf3157b2008-08-14 05:00:03 +00002458- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2459 since mimetools itself is deprecated. Because modules are cached, all
2460 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2461
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002462- Issue #3134: shutil referenced undefined WindowsError symbol.
2463
Robert Schuppenies14646332008-08-10 11:01:53 +00002464- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2465 menu entries were not deleted.
2466
Brett Cannon83e81842008-08-09 23:30:55 +00002467- Copied the implementation of reduce() to _functools.reduce() to have a
2468 version that did not raise a DeprecationWarning under -3.
2469
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002470- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2471 a MemoryError rather than silently stop the iteration.
2472
Guido van Rossum59ce9012008-08-09 14:55:34 +00002473- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2474 to _sre.compile() will now be rejected. This should not affect anybody
2475 since the re.compile() function never generates invalid re-bytecode.
2476
Skip Montanaroa032bf42008-08-08 22:52:51 +00002477- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

2482 the reload() built-in has been removed.
2483
Brett Cannon7e30b672008-08-04 21:52:25 +00002484- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002485 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002496 asking for a specific length. This problem only affected files opened
2497 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002498

2524 mode 0600 rather than 000 under Unix.
2525
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002526- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2557 an integer using operator.index().
2558
Mark Dickinson64b7e502008-07-16 09:40:03 +00002559- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2560 produced a ValueError instead of giving the correct float.
2561
Eric Smitha5fa5a22008-07-16 00:11:49 +00002562- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2563 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2564
Mark Dickinson7103aa42008-07-15 19:08:33 +00002565- Issue #3008: the float type has a new instance method 'float.hex'

Nick Coghlan6d6bd442008-07-15 15:40:22 +00002569- Issue #2235: __hash__ is once again inherited by default. To allow
2570 collections.Hashable to remain meaningful in the presence of the
2571 default hash implementation (object.__hash__), it is now possible
2572 to explicit block inheritance of hash by setting __hash__=None at
2573 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2574 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00002576- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2577 the parent module cannot be found while performing an absolute import.
2578 This means that an incorrectly defined __package__ attribute will
2579 now only prevent relative imports in that module rather than causing
2580 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002594- Issue #3004: Minor change to slice.indices(): the start and stop
2595 arguments are now treated identically, making the behaviour easier
2596 to describe and understand. For example, slice(None, -10,
2597 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2598 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2599 10, -1).

2642 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002643 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00003053 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003054
3055 This is controlled by the configure argument ``--with-universal-archs``:

3058
3059 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3060
3061 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

3102 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00003104- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003115- Issue #1631171: Re-implement the 'warnings' module in C (the
3116 original Python code has been kept as backup). This will allow for
3117 using the 'warning's machinery in such places as the parser where
3118 use of pure Python code is not possible. Both the ``showarning()``
3119 and ``formatwarning()`` gain an optional 'line' argument which is
3120 not called by default for backwards-compatibility reasons. Setting
3121 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Issue #2550: The approach used by client/server code for obtaining
3186 ports to listen on in network-oriented tests has been refined in an
3187 effort to facilitate running multiple instances of the entire
3188 regression test suite in parallel without issue.
3189 test_support.bind_port() has been fixed such that it will always
3190 return a unique port -- which wasn't always the case with the
3191 previous implementation, especially if socket options had been set
3192 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3193 new implementation of bind_port() will actually raise an exception
3194 if it is passed an AF_INET/SOCK_STREAM socket with either the
3195 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3196 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3197 the socket it's been passed. This currently only applies to
3198 Windows. This option prevents any other sockets from binding to the
3199 host/port we've bound to, thus removing the possibility of the
3200 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3201 when a second SOCK_STREAM socket binds and accepts to a host/port
3202 that's already been bound by another socket. The optional preferred
3203 port parameter to bind_port() has been removed. Under no
3204 circumstances should tests be hard coding ports!
3205
3206 test_support.find_unused_port() has also been introduced, which will
3207 pass a temporary socket object to bind_port() in order to obtain an
3208 unused port. The temporary socket object is then closed and
3209 deleted, and the port is returned. This method should only be used
3210 for obtaining an unused port in order to pass to an external program
3211 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3212 a parameter to a server-oriented class that doesn't give you direct
3213 access to the underlying socket used.
3214
3215 Finally, test_support.HOST has been introduced, which should be used
3216 for the host argument of any relevant socket calls (i.e. bind and
3217 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003218
3219 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003221 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3222 test_asynchat and test_socket_ssl.
3223
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224 It is now possible for multiple instances of the regression test
3225 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003391- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
3392 values on 32-bit vs. 64-bit python interpreters. Both were correct,
3393 but they now both return a signed integer object for consistency.

3492-----------------
3493
Fred Drakea8ee94b2008-03-01 02:45:07 +00003494- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003495 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003497- Issue #2067: file.__exit__() now calls subclasses' close() method.
3498
3499- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003500
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003501- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003502 issue 215555 for a discussion.
3503
Eric Smitha73fbe72008-02-23 03:09:44 +00003504- Added the future_builtins module, which contains hex() and oct().
3505 These are the PEP 3127 version of these functions, designed to be
3506 compatible with the hex() and oct() builtins from Python 3.0. They
3507 differ slightly in their output formats from the existing, unchanged
3508 Python 2.6 builtins. The expected usage of the future_builtins
3509 module is:
3510 from future_builtins import hex, oct
3511
Eric Smith7ef40bf2008-02-20 23:34:22 +00003512- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3513 exponents for exponents with absolute value < 100. Follows C99
3514 standard. This is a change on Windows, which would use 3 digits.
3515 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3516 so that any alterations it does to the resulting string will be
3517 available in stringlib/formatter.h (for float.__format__).
3518
Eric Smith5a3c1352008-02-19 13:21:56 +00003519- Implemented PEP 3101, Advanced String Formatting. This adds a new
3520 builtin format(); a format() method for str and unicode; a
3521 __format__() method to object, str, unicode, int, long, float, and
3522 datetime; the class string.Formatter; and the C API
3523 PyObject_Format().
3524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- Fixed several potential crashes, all caused by specially crafted
3526 __del__ methods exploiting objects in temporarily inconsistent
3527 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003528
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003529- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003530 prevent a possible crash: an Abstract Base Class would try to access
3531 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003532
Georg Brandl3ee81df2008-05-17 18:14:43 +00003533- Fixed repr() and str() of complex numbers with infinity or nan as
3534 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003535
Georg Brandl3ee81df2008-05-17 18:14:43 +00003536- Clear all free lists during a gc.collect() of the highest generation
3537 in order to allow pymalloc to free more arenas. Python may give back
3538 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003539
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540- Issue #2045: Fix an infinite recursion triggered when printing a
3541 subclass of collections.defaultdict, if its default_factory is set
3542 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003543
Christian Heimesf75dbef2008-02-08 00:11:31 +00003544- Fixed a minor memory leak in dictobject.c. The content of the free
3545 list was not freed on interpreter shutdown.
3546
Georg Brandl3ee81df2008-05-17 18:14:43 +00003547- Limit free list of method and builtin function objects to 256
3548 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003549
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3551 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003552 to compact the internal free lists of pre-allocted ints and floats.
3553
Georg Brandl3ee81df2008-05-17 18:14:43 +00003554- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3555 calls. Python expected the return type int but the fork familie
3556 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003557
Georg Brandl3ee81df2008-05-17 18:14:43 +00003558- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3559 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003560
Georg Brandl3ee81df2008-05-17 18:14:43 +00003561- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3562 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003567- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3568 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003569
Georg Brandl3ee81df2008-05-17 18:14:43 +00003570- Patch #1473257: generator objects gain a gi_code attribute. This is
3571 the same object as the func_code attribute of the function that
3572 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- Issue #1920: "while 0" statements were completely removed by the
3575 compiler, even in the presence of an "else" clause, which is
3576 supposed to be run when the condition is false. Now the compiler
3577 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003578
Guido van Rossumeead05f2008-01-24 18:21:02 +00003579- A few crashers fixed: weakref_in_del.py (issue #1377858);
3580 loosing_dict_ref.py (issue #1303614, test67.py);
3581 borrowed_ref_[34].py (not in tracker).
3582
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003583- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003584 suppressed while an extension is loaded by calling SetErrorMode in
3585 dynload_win.c. The error is still reported properly.
3586
Georg Brandl3ee81df2008-05-17 18:14:43 +00003587- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003588 several extension methods and modules do not work without unicode
3589 support.
3590
Georg Brandl26543b12008-01-21 18:36:51 +00003591- Issue #1882: when compiling code from a string, encoding cookies in the
3592 second line of code were not always recognized correctly.
3593
Georg Brandl14404b62008-01-19 19:27:05 +00003594- Issue #1679: "0x" was taken as a valid integer literal.
3595
Georg Brandl6caad7d2008-01-26 14:19:22 +00003596- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003597 added.
3598
Christian Heimesc94e2b52008-01-14 04:13:37 +00003599- sys.float_info / PyFloat_GetInfo: The floating point information
3600 object was converted from a dict to a specialized structseq object.
3601
Georg Brandl3ee81df2008-05-17 18:14:43 +00003602- Patch #1816: Added sys.flags structseq. It exposes the status of
3603 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003604
Georg Brandl3ee81df2008-05-17 18:14:43 +00003605- Objects/structseq.c: Implemented new structseq representation. The
3606 patch makes structseqs (e.g. the return value of os.stat) more
3607 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003608
Georg Brandl3ee81df2008-05-17 18:14:43 +00003609- Patch #1700288: added a type attribute cache that caches method
3610 accesses, resulting in speedups in heavily object-oriented code.

3618 envvar and sys.dont_write_bytecode attribute. All these can be set
3619 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003620
Georg Brandl3ee81df2008-05-17 18:14:43 +00003621- Improve some exception messages when Windows fails to load an
3622 extension module. Now we get for example '%1 is not a valid Win32
3623 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003624

3628 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003629
Christian Heimes0a8143f2007-12-18 23:22:54 +00003630- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003631 and INF. float("nan"), float("inf") and float("-inf") now work on
3632 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003633
Georg Brandl3ee81df2008-05-17 18:14:43 +00003634- Compiler now generates simpler and faster code for dictionary
3635 literals. The oparg for BUILD_MAP now indicates an estimated
3636 dictionary size. There is a new opcode, STORE_MAP, for adding
3637 entries to the dictionary.

3680
Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- The enumerate() builtin function is no longer bounded to sequences
3682 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3683 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003684
Georg Brandl3ee81df2008-05-17 18:14:43 +00003685- Issue #1686386: Tuple's tp_repr did not take into account the
3686 possibility of having a self-referential tuple, which is possible
3687 from C code. Nor did object's tp_str consider that a type's tp_str
3688 could do something that could lead to an inifinite recursion.
3689 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3690 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003691
Georg Brandl3ee81df2008-05-17 18:14:43 +00003692- Issue #1164: It was possible to trigger deadlock when using the
3693 'print' statement to write to a file since the GIL was not released
3694 as needed. Now PyObject_Print() does the right thing along with
3695 various tp_print implementations of the built-in types and those in
3696 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00003705- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003706 PyObject_Call() never calling back out to Python code to trigger
3707 recursion depth updates/checks. Required the creation of a static
3708 RuntimeError instance in case normalizing an exception put the
3709 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00003726 __*__ attributes. (Some already existed, e.g., __doc__ and
3727 __name__.)

3734
Collin Winter62903052007-05-18 23:11:24 +00003735- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003736 "except E as target:". This is to provide forwards compatibility
3737 with Python 3.0.

3743
Vinay Sajip8549ce32007-05-06 17:53:37 +00003744- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003745 setting a plain string, ie don't expand to single letter identifiers.
3746
Raymond Hettinger13936692007-04-11 18:40:58 +00003747- Request #1191699: Slices can now be pickled.
3748
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003749- Request #1193128: str.translate() now allows a None argument for

3751 remaining characters.
3752
Georg Brandl5cb76c12007-03-21 09:00:39 +00003753- Patch #1682205: a TypeError while unpacking an iterable is no longer

3757
Guido van Rossum143b5642007-03-23 04:58:42 +00003758- Bug #1683368: The object.__init__() and object.__new__() methods are
3759 now stricter in rejecting excess arguments. The only time when
3760 either allows excess arguments is when it is not overridden and the
3761 other one is. For backwards compatibility, when both are
3762 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003763 warning later). Also, type.__init__() insists on the same signature
3764 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3767 object to complex using its __complex__() method before falling back
3768 to the __float__() method. Therefore, the functions in the cmath
3769 module now can operate on objects that define a __complex__()
3770 method.

3787
Georg Brandl7b9c5552007-03-12 14:30:05 +00003788- Bug #1678647: write a newline after printing an exception in any
3789 case, even when converting the value to a string failed.
3790
Georg Brandl871f1bc2007-03-12 13:17:36 +00003791- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003792 its argument, if it exists. If not, it will work like before. This
3793 allows customizing the output of dir() in the presence of a
3794 __getattr__().

3798
Georg Brandl3ee81df2008-05-17 18:14:43 +00003799- Patch #1675981: remove unreachable code from ``type.__new__()``

3803 parthensized forms. This means complex(repr(x)) now works instead of
3804 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003805
Georg Brandlaa2321b2007-03-07 00:40:28 +00003806- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003807 makes the filenames the warning module prints much more sensible
3808 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003809

Georg Brandl0fca97a2007-03-05 22:28:08 +00003821- Patch #1674228: when assigning a slice (old-style), check for the
3822 sq_ass_slice instead of the sq_slice slot.
3823
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824- When printing an unraisable error, don't print exceptions. before
3825 the name. This duplicates the behavior whening normally printing
3826 exceptions.

4392
Georg Brandl92a6bae2007-03-13 17:43:32 +00004393- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004394 are set for invalid interpolation sequences that would lead to

4451 TestCase and TestSuite subclasses (not instances) are no longer
4452 accepted in TestSuite.addTest(). This should cause no
4453 incompatibility since it never made sense with ordinary subclasses
4454 -- the failure just occurred later, with a more cumbersome
4455 exception.

4739 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004740
Georg Brandl3ee81df2008-05-17 18:14:43 +00004741- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004742 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004744 does not claim to support starttls. Adds the
4745 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004844 time so that opening a database previously created with the DB_DUP
4845 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4846 opens. Specifically: dictionary assignment to a DB object will
4847 replace all values for a given key when the database allows
4848 duplicate values. DB users should use DB.put(k, v) when they want
4849 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004850

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005128- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005129 periodic threadstate and signal checking in tight loops. By
5130 default, this option is turned-off. It should only be enabled in
5131 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005132

5182-----
5183
Georg Brandl3ee81df2008-05-17 18:14:43 +00005184- Unified naming convention for free lists and their limits. All free
5185 lists in Object/ are named ``free_list``, the counter ``numfree``
5186 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5187 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005188
Georg Brandl3ee81df2008-05-17 18:14:43 +00005189- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5190 to ``PyTuple_SetItem``, it can be used to populate a brand new
5191 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005192

5200
5201- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5202 ``PyFloat_GetInfo()`` to the float API.
5203
Georg Brandl3ee81df2008-05-17 18:14:43 +00005204- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5205 of w# format code incorrectly truncated the length to an int, even
5206 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5207 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005208
Georg Brandl3ee81df2008-05-17 18:14:43 +00005209- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5227- Fix some leftovers from the conversion from int to Py_ssize_t
5228 (relevant to strings and sequences of more than 2**31 items).
5229
5230- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5231 outside of pystate.c and should not be necessary.
5232
Georg Brandl3ee81df2008-05-17 18:14:43 +00005233- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5234 absolute imports. In earlier versions they might have used relative
5235 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005236
Georg Brandl3ee81df2008-05-17 18:14:43 +00005237- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5238 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005239
Georg Brandl3ee81df2008-05-17 18:14:43 +00005240- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005265- Removed the macfs module. It had been deprecated since Python 2.5.
5266 This lead to the deprecation of macostools.touched() as it relied
5267 solely on macfs and was a no-op under OS X.
