16 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
17
Victor Stinnerb4b0a292010-01-31 22:32:15 +000018- Issue #7819: Check sys.call_tracing() arguments types.
19
Mark Dickinson36ecd672010-01-29 17:11:39 +000020- Issue #7788: Fix an interpreter crash produced by deleting a list
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.

57
Antoine Pitroud840e512010-02-04 20:20:18 +000058- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
59 specified, rather than fall through to AF_PACKET (in the `socket` module).
60 Also, raise ValueError rather than TypeError when an unknown TIPC address
61 type is specified. Patch by Brian Curtin.
62
Vinay Sajip28c382f2010-02-04 18:48:53 +000063- logging: Implemented PEP 391.
64
Antoine Pitrouf3fa0742010-01-31 22:26:04 +000065- Issue #6939: Fix file I/O objects in the `io` module to keep the original
66 file position when calling `truncate()`. It would previously change the
67 file position to the given argument, which goes against the tradition of
68 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
69
Benjamin Petersone06f7112010-01-28 02:15:02 +000070- UserDict is now a new-style class.
71
Antoine Pitrou94c33eb2010-01-27 20:59:50 +000072- Issue #7610: Reworked implementation of the internal
73 :class:`zipfile.ZipExtFile` class used to represent files stored inside
74 an archive. The new implementation is significantly faster and can
75 be wrapped in a :class:`io.BufferedReader` object for more speedups.
76 It also solves an issue where interleaved calls to `read()` and
77 `readline()` give wrong results. Patch by Nir Aides.
78
Benjamin Peterson2deb5c72010-01-27 02:16:42 +000079- Issue #7792: Registering non-classes to ABCs raised an obscure error.
80

84 the release file is empty.
85
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +000086- Issue #7748: Since unicode values are supported for some metadata options
87 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
88 encoded string for them. This ensure that the upload and register commands
89 send the right values to PyPI without any error.
90
R. David Murrayed44dfa2010-01-16 05:15:17 +000091- Issue #1670765: Prevent email.generator.Generator from re-wrapping

Tarek Ziadédc0f4872010-01-11 22:50:29 +0000111- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since
112 Extension extra options may change the output without changing the .c
113 file). Initial patch by Collin Winter.

125 private memory allocation scheme in dtoa.c and use PyMem_Malloc and
126 PyMem_Free instead. Also disable caching of powers of 5.
127
Ronald Oussorena55af9a2010-01-17 16:25:57 +0000128- Issue #7658: Ensure that the new pythonw executable works on OSX 10.4

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000150What's New in Python 2.7 alpha 2?
151=================================
152
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000153*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000154
155Core and Builtins
156-----------------
157
Benjamin Petersonecdae192010-01-04 00:43:01 +0000158- The __complex__ method is now looked up on the class of instances to make it
159 consistent with other special methods.
160
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000161- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
162 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
163
Mark Dickinson1b34d252010-01-01 17:27:30 +0000164- Issue #5080: A number of functions and methods previously produced a
165 DeprecationWarning when passed a float argument where an integer was
166 expected. These functions and methods now raise TypeError instead.
167 The majority of the effects of this change are in the extension
168 modules, but some core functions and methods are affected: notably
169 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
170 methods.
171
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000172- Issue #7604: Deleting an unset slotted attribute did not raise an
173 AttributeError.

180
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000181- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
182 used to drop the time part of the result.
183
Mark Dickinson46572832009-12-27 14:55:57 +0000184- Issue #1811: improve accuracy and cross-platform consistency for
185 true division of integers: the result of a/b is now correctly
186 rounded for ints a and b (at least on IEEE 754 platforms), and in
187 particular does not depend on the internal representation of a long.
188
Ezio Melottif84caf42009-12-24 22:25:17 +0000189- Issue #6108: unicode(exception) and str(exception) should return the same
190 message when only __str__ (and not __unicode__) is overridden in the subclass.
191
Ronald Oussoren92919a62009-12-24 13:30:58 +0000192- Issue #6834: replace the implementation for the 'python' and 'pythonw'
193 executables on OSX.
194
195 These executables now work properly with the arch(1) command:
196 ``arch -ppc python`` will start a universal binary version of python
197 in PPC mode (unlike previous releases).
198
R. David Murray0a0a1a82009-12-14 16:28:26 +0000199- Issue #1680159: unicode coercion during an 'in' operation no longer masks
200 the underlying error when the coercion fails for the left hand operand.
201
Benjamin Peterson4895af42009-12-13 16:36:53 +0000202- Issue #7491: Metaclass's __cmp__ method was ignored.
203
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000204- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +0000205 in the middle of populating a tuple. Patch by Florent Xicluna.

218 by Arfrever.
219
Antoine Pitrou80157252010-01-08 19:20:17 +0000220- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
221 renaming of `cPickle` to `pickle`. The warning was annoying since there's
222 no alternative to cPickle if you care about performance. Patch by Florent
223 Xicluna.
224
Antoine Pitrou0d423b82010-01-07 17:46:49 +0000225- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

232 and make it implement the `io.BufferedIOBase` ABC to allow for further
233 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
234
235- Issue #3972: httplib.HTTPConnection now accepts an optional source_address

250 the Distutils upload command to avoid an error when PyPI reads it.
251 This occurs on long passwords. Initial patch by JP St. Pierre.
252
253- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000254 Patch by Tatsuhiro Tsujikawa.
255
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000256- Issue #7349: Make methods of file objects in the io module accept None as an
257 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
258 the same as passing no argument.
259
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000260- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
261 like other file objects.
262

284 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
285 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
286 arguments for integer format codes (other than 'L'): previously an
287 attempt to pass a float resulted in a DeprecationWarning; now it
288 gives a TypeError. For the 'L' format code (which previously had no
289 warning) there is now a DeprecationWarning.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000334- Issue #7419: setlocale() could crash the interpreter on Windows when called
335 with invalid values.
336
Eric Smithc4ab8332009-11-29 17:40:57 +0000337- Issue #3382: 'F' formatting for float and complex now convert the
338 result to upper case. This only affects 'inf' and 'nan', since 'f'
339 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000340
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000341- Remove switch from "%f" formatting to "%g" formatting for floats
342 larger than 1e50 in absolute value.
343
Mark Dickinson18cfada2009-11-23 18:46:41 +0000344- Remove restrictions on precision when formatting floats. E.g.,
345 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
346 requested 120 significant digits instead.
347
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000348- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000352- Issue #7085: Fix crash when importing some extensions in a thread
353 on MacOSX 10.6.
354
Mark Dickinsonb678de82009-11-19 18:41:49 +0000355- Issue #7117: repr(x) for a float x returns a result based on the
356 shortest decimal string that's guaranteed to round back to x under
357 correct rounding (with round-half-to-even rounding mode).
358 Previously it gave a string based on rounding x to 17 decimal digits.
359 repr(x) for a complex number behaves similarly. On platforms where
360 the correctly-rounded strtod and dtoa code is not supported (see below),
361 repr is unchanged.
362
363- Issue #7117: On almost all platforms: float-to-string and
364 string-to-float conversions within Python are now correctly rounded.
365 Places these conversions occur include: str for floats and complex
366 numbers; the float and complex constructors; old-style and new-style
367 numeric formatting; serialization and deserialization of floats and
368 complex numbers using marshal, pickle and json; parsing of float and
369 imaginary literals in Python code; Decimal-to-float conversion.
370
371 The conversions use a Python-adapted version of David Gay's
372 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
373 functions. This code is supported on Windows, and on Unix-like
374 platforms using gcc, icc or suncc as the C compiler. There may be a
375 small number of platforms on which correct operation of this code
376 cannot be guaranteed, so the code is not used: notably, this applies
377 to platforms where the C double format is not IEEE 754 binary64, and
378 to platforms on x86 hardware where the x87 FPU is set to 64-bit
379 precision and Python's configure script is unable to determine how
380 to change the FPU precision. On these platforms conversions use the
381 platform strtod and dtoa, as before.
382
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000383- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000384 now uses the correctly-rounded string <-> float conversions
385 described above (when available), and so produces correctly rounded
386 results that will display nicely under the float repr. There are
387 two related small changes: (1) round now accepts any class with an
388 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000389 floats for the second argument), and (2) an excessively large second
390 integer argument (e.g., round(1.234, 10**100)) no longer raises an
391 exception.
392
Philip Jenveyfab8be22009-11-17 02:42:26 +0000393- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

534 (1) inf and nan strings with trailing whitespace were incorrectly
535 rejected; (2) parsing of strings representing infinities and nans
536 was locale aware; and (3) the interpretation of fromhex('-nan')
537 didn't match that of float('-nan').
538
Eric Smitha985a3a2009-05-05 18:26:08 +0000539- Issue #5920: For float.__format__, change the behavior with the
540 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
541 to be like 'g' but with at least one decimal point and with a
542 default precision of 12. Previously, the behavior the same but with
543 a default precision of 6. This more closely matches str(), and
544 reduces surprises when adding alignment flags to the empty
545 presentation type. This also affects the new complex.__format__ in
546 the same way.

Mark Dickinson0b666bf2009-03-23 18:25:13 +0000615- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
616 improve its performance. Long divisions and remainder operations
617 are now between 50% and 150% faster.
618
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000619- Issue #4258: Make it possible to use base 2**30 instead of base
620 2**15 for the internal representation of integers, for performance
621 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
622 --enable-big-digits option to configure, which overrides the
623 default. Add sys.long_info structseq to provide information about
624 the internal format.
625
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000626- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

630 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
631 and sizeof(Py_UNICODE) == 2.
632
Eric Smith6f42edb2009-03-14 11:57:26 +0000633- Issue #5237: Allow auto-numbered fields in str.format(). For
634 example: '{} {}'.format(1, 2) == '1 2'.
635
Brett Cannon6c4cff02009-03-11 04:51:06 +0000636- Issue #3652: Make the 'line' argument for warnings.showwarning() a

638
Eric Smithe9fb6862009-02-20 14:02:36 +0000639- Issue #5247: Improve error message when unknown format codes are

641 float arguments.
642
Raymond Hettinger08259e82009-02-18 23:10:19 +0000643- Running Python with the -3 option now also warns about classic division
644 for ints and longs.
645
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000646- Issue #5260: Long integers now consume less memory: average
647 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
648 on a 64-bit system.
649
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000650- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

655
Benjamin Petersone18ef192009-01-20 14:21:16 +0000656- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
657
Georg Brandl29c6a282009-04-05 20:23:13 +0000658- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000659 were suppressing all exceptions. These include list(), filter(), map(),
660 zip(), and bytearray().
661
Benjamin Peterson596d3062009-01-19 15:42:23 +0000662- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
663 functions.
664
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000665- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

669
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000670- Issue #4935: The overflow checking code in the expandtabs() method common
671 to str, bytes and bytearray could be optimized away by the compiler, letting
672 the interpreter segfault instead of raising an error.
673
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000674- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000681- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
682 collecting the oldest generation) so that allocating lots of objects without
683 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000684 Martin von Löwis at

688
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000689- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
690 an existing .py counterpart, override the co_filename attributes of all
691 code objects if the original filename is obsolete (which can happen if the
692 file has been renamed, moved, or if it is accessed through different paths).
693 Patch by Ziga Seilnacht and Jean-Paul Calderone.
694
Martin v. Löwis5344c992009-01-02 20:32:55 +0000695- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000697- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
698 file with `str' filename on Windows.
699
Antoine Pitrouaa687902009-01-01 14:11:22 +0000700- Issue #3680: Reference cycles created through a dict, set or deque iterator
701 did not get collected.
702
Nick Coghlan180e4002008-12-30 01:18:48 +0000703- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
704 where the tp_hash and tp_dict slots are both NULL.
705
Benjamin Peterson7af65562008-12-29 17:56:58 +0000706- Issue #4764: With io.open, IOError.filename is set when trying to open a

713 bytearray.translate(). It was always allowed for bytes.translate().
714
Skip Montanarof205c132008-12-23 03:30:15 +0000715- Added test case to ensure attempts to read from a file opened for writing
716 fail.
717
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000718- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

729
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000730- Issue #4597: Fixed several opcodes that weren't always propagating
731 exceptions.
732
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000733- Issue #4445: Replace "sizeof(PyStringObject)" with
734 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
735 str instances. On a typical machine this saves 3 bytes of memory
736 (on average) per string allocation.
737
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000738- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
739 interpreter to abort ("Fatal Python error: Could not reset the stack!")
740 instead of throwing a MemoryError.
741
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000742- Issue #3689: The list reversed iterator now supports __length_hint__
743 instead of __len__. Behavior now matches other reversed iterators.
744
Benjamin Petersonc078f922008-11-21 22:27:24 +0000745- Issue #4367: Python would segfault during compiling when the unicodedata
746 module couldn't be imported and \N escapes were present.
747
Vinay Sajip213faca2008-12-03 23:22:58 +0000748- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000749 method on file objects with closefd=False. The file descriptor is still
750 kept open but the file object behaves like a closed file. The ``FileIO``
751 object also got a new readonly attribute ``closefd``.
752
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000753- Issue #4348: Some bytearray methods returned that didn't cause any change to
754 the bytearray, returned the same bytearray instead of a copy.
755
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000756- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
757

761
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000762- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

764
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000765- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
766 method does not return iterators for the 4th and 5th items.
767
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000768- Issue #4209: Enabling unicode_literals and the print_function in the same
769 __future__ import didn't work.
770
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000771- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000772 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000773
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000774- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
775 returned a path longer than MAX_PATH. (But It's doubtful this code path is
776 really executed because I cannot move to such directory on win2k)
777
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000778- Issue #4069: When set.remove(element) is used with a set element, the element
779 is temporarily replaced with an equivalent frozenset. But the eventual
780 KeyError would always report the empty frozenset([]) as the missing key. Now
781 it correctly refers to the initial element.
782
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000783- Issue #4509: Various issues surrounding resize of bytearray objects to

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000798- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
799 returned them on 64bit platforms.
800
Walter Dörwalded960ac2009-05-03 22:36:33 +0000801- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
802 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
803 step. This avoids problems with counting UTF-8 bytes that ignores the effect
804 of using the replace error handler in PyUnicode_DecodeUTF8().
805
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000806- Issue #3739: The unicode-internal encoder now reports the number of characters
807 consumed like any other encoder (instead of the number of bytes).
808
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000809- Issue #2422: When compiled with the ``--with-valgrind`` option, the
810 pymalloc allocator will be automatically disabled when running under
811 Valgrind. This gives improved memory leak detection when running
812 under Valgrind, while taking advantage of pymalloc at other times.

1991 - Packing a float now always gives a Deprecation Warning.
1992 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1993
1994 - If x is not an int, long or float, then packing x will always
1995 result in struct.error. Previously an x with an __int__ method
1996 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1997 ,'*i', '*l', and an x with a __long__ method could be packed by
1998 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1999 TypeError used to be raised (with a confusing error message) for
2000 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002194- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2195 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2196 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2197 ``printf`` function, whereas PyString_FromFormat has an independent
2198 implementation and uses "%zd" on all platforms for size_t values.
2199 This makes a difference on win64, where ``printf`` needs "%Id" to display
2200 64bit values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002219- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002220 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2221 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2222 when given a tuple of classes as second argument, were looking up
2223 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2224 type object.

2295 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2296 for catch_warnings() also led to an improvement in the raising of a
2297 DeprecationWarning related to warnings.warn_explicit().
2298

2321
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002322- Issue #2975: When compiling several extension modules with Visual Studio 2008
2323 from the same python interpreter, some environment variables would grow
2324 without limit.
2325
Benjamin Peterson37346b22008-08-23 20:27:43 +00002326- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002363What's New in Python 2.6 beta 3?
2364================================
2365
Barry Warsaw07a4a382008-08-21 01:15:08 +00002366*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002367
2368Core and Builtins
2369-----------------
2370
Guido van Rossumf8402962008-08-20 15:01:50 +00002371- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2372 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2373 extensions do not automatically benefit from the class attribute
2374 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2375 to their tp_flags field if they care. This is a backwards
2376 compatibility feature; in 3.0, all types will use the cache by
2377 default.
2378
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002379- Keyword arguments can now follow starred arguments. (``f(a, *args,
2380 keyword=23)`` is now valid syntax.)
2381
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002382- ctypes function pointers that are COM methods have a boolean True
2383 value again.
2384
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002385- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2386 by denying s# to parse objects that have a releasebuffer procedure,
2387 and introducing s*.
2388
Georg Brandl1e13ea92008-08-11 09:07:59 +00002389- Issue #3537: Fix an assertion failure when an empty but presized dict
2390 object was stored in the freelist.
2391
Mark Dickinsonb6467572008-08-04 21:30:09 +00002392- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2393 ValueError consistently across platforms.
2394
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002395- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2396 (64bit Unix, for example), unichr() would truncate its argument and return
2397 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2398
Neal Norwitze7d8be82008-07-31 17:17:14 +00002399- Apply security patches from Apple.
2400
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002401- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2402 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2403
Antoine Pitrou92f82162008-07-25 22:22:08 +00002404- Issue #1819: function calls with several named parameters are now on
2405 average 35% faster (as measured by pybench).
2406
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002407- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2408 the python debugger steps into a class statement: the free variables (local
2409 variables defined in an outer scope) would be deleted from the outer scope.
2410
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002411- Issue #2620: Overflow checking when allocating or reallocating memory
2412 was not always being done properly in some python types and extension
2413 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2414 all been updated to perform better checks and places in the code that
2415 would previously leak memory on the error path when such an allocation
2416 failed have been fixed.
2417
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002418Library
2419-------
2420

2422
Benjamin Petersone977ad42008-08-20 01:42:01 +00002423- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2424 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2425
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002426- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2427 version reported by these tools does not necessarily follow the python
2428 version numbering scheme, so the module is less strict when parsing it.
2429
Nick Coghlanf70385a2008-08-18 12:42:46 +00002430- Issue #2235: Added Py3k warnings for types which will become unhashable
2431 under the stricter __hash__ inheritance rules in 3.0. Several types
2432 which did not meet the rules for hash invariants and were already
2433 unhashable in 3.0 have now been explicitly flagged as unhashable in
2434 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2435 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2436
Brett Cannon88f801d2008-08-18 00:46:22 +00002437- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2445
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002446- Issue #3575: Incremental decoder's decode function now takes bytearray
2447 by using 's*' instead of 't#'.
2448
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002449- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002450 fails unicode conversion on 2nd parameter. (windows only)
2451
Facundo Batista94f243a2008-08-17 03:38:39 +00002452- Issue 2464. urllib2 now supports a malformation in the URL received
2453 in a redirect.
2454
Brett Cannonabe423e2008-08-16 21:47:07 +00002455- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002456 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002457
Facundo Batistaeb90b782008-08-16 14:44:07 +00002458- Issue #2776: fixed small issue when handling an URL with double slash
2459 after a 302 response in the case of not going through a proxy.
2460
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002461- Issue #2676: in the email package, content-type parsing was hanging on
2462 pathological input because of quadratic or exponential behaviour of a
2463 regular expression.
2464
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002465- Issue #3476: binary buffered reading through the new "io" library is now
2466 thread-safe.
2467
Brett Cannonbf3157b2008-08-14 05:00:03 +00002468- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2469 since mimetools itself is deprecated. Because modules are cached, all
2470 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2471
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002472- Issue #3134: shutil referenced undefined WindowsError symbol.
2473
Robert Schuppenies14646332008-08-10 11:01:53 +00002474- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2475 menu entries were not deleted.
2476
Brett Cannon83e81842008-08-09 23:30:55 +00002477- Copied the implementation of reduce() to _functools.reduce() to have a
2478 version that did not raise a DeprecationWarning under -3.
2479
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002480- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2481 a MemoryError rather than silently stop the iteration.
2482
Guido van Rossum59ce9012008-08-09 14:55:34 +00002483- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2484 to _sre.compile() will now be rejected. This should not affect anybody
2485 since the re.compile() function never generates invalid re-bytecode.
2486
Skip Montanaroa032bf42008-08-08 22:52:51 +00002487- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002506 asking for a specific length. This problem only affected files opened
2507 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002508

2534 mode 0600 rather than 000 under Unix.
2535
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002536- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2573 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2574
Mark Dickinson7103aa42008-07-15 19:08:33 +00002575- Issue #3008: the float type has a new instance method 'float.hex'
2576 and a new class method 'float.fromhex' to convert floating-point
2577 numbers to and from hexadecimal strings, respectively.
2578
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002579- Issue #2235: __hash__ is once again inherited by default. To allow
2580 collections.Hashable to remain meaningful in the presence of the
2581 default hash implementation (object.__hash__), it is now possible
2582 to explicit block inheritance of hash by setting __hash__=None at
2583 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2584 level.
2585
Nick Coghlanb028f502008-07-13 14:52:36 +00002586- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2587 the parent module cannot be found while performing an absolute import.
2588 This means that an incorrectly defined __package__ attribute will
2589 now only prevent relative imports in that module rather than causing
2590 all imports from that module to fail.
2591
Nick Coghlan14ff9942008-07-08 14:21:42 +00002592- Issue #2517: Allow unicode messages in Exceptions again by correctly

2602 another thread's dictionary.
2603
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002604- Issue #3004: Minor change to slice.indices(): the start and stop
2605 arguments are now treated identically, making the behaviour easier
2606 to describe and understand. For example, slice(None, -10,
2607 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2608 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2609 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00002611- Issue #3219: Calling a function with repeated keyword arguments,
2612 f(a=2, a=23), would not cause a syntax error. This was a regression
2613 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002614

2616 other freelists. Changes their CompactFreeList apis into
2617 ClearFreeList apis and calls them via gc.collect().

2623 api functions without holding the GIL, which could lead to a fatal
2624 error when they failed.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002651- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2652 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002653 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002654 content-length. The problem had been corrected in the 2.4 branch, but never

3130 not called by default for backwards-compatibility reasons. Setting
3131 ``warnings.showwarning()`` to an implementation that lacks support
3132 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003195- Issue #2550: The approach used by client/server code for obtaining
3196 ports to listen on in network-oriented tests has been refined in an
3197 effort to facilitate running multiple instances of the entire
3198 regression test suite in parallel without issue.
3199 test_support.bind_port() has been fixed such that it will always
3200 return a unique port -- which wasn't always the case with the
3201 previous implementation, especially if socket options had been set
3202 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3203 new implementation of bind_port() will actually raise an exception
3204 if it is passed an AF_INET/SOCK_STREAM socket with either the
3205 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3206 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3207 the socket it's been passed. This currently only applies to
3208 Windows. This option prevents any other sockets from binding to the
3209 host/port we've bound to, thus removing the possibility of the
3210 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3211 when a second SOCK_STREAM socket binds and accepts to a host/port
3212 that's already been bound by another socket. The optional preferred
3213 port parameter to bind_port() has been removed. Under no
3214 circumstances should tests be hard coding ports!
3215
3216 test_support.find_unused_port() has also been introduced, which will
3217 pass a temporary socket object to bind_port() in order to obtain an
3218 unused port. The temporary socket object is then closed and
3219 deleted, and the port is returned. This method should only be used
3220 for obtaining an unused port in order to pass to an external program
3221 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3222 a parameter to a server-oriented class that doesn't give you direct
3223 access to the underlying socket used.
3224
3225 Finally, test_support.HOST has been introduced, which should be used
3226 for the host argument of any relevant socket calls (i.e. bind and
3227 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003228
3229 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003230 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003231 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3232 test_asynchat and test_socket_ssl.
3233
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234 It is now possible for multiple instances of the regression test
3235 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003401- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
3402 values on 32-bit vs. 64-bit python interpreters. Both were correct,
3403 but they now both return a signed integer object for consistency.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003419 optional: it defaults to the traceback of the exception that is
3420 currently being handled (is mandatory to be in the middle of an
3421 exception, otherwise it raises ValueError).

3437 from 't' to '?'.
3438
Thomas Heller78b8f442008-03-05 14:53:39 +00003439- The bundled libffi copy is now in sync with the recently released
3440 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003441 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
3442 files are used. On all linux systems the --with-system-ffi

3501Core and builtins
3502-----------------
3503
Fred Drakea8ee94b2008-03-01 02:45:07 +00003504- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003505 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003506
Georg Brandlad61bc82008-02-23 15:11:18 +00003507- Issue #2067: file.__exit__() now calls subclasses' close() method.
3508
3509- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003510
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003511- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003512 issue 215555 for a discussion.
3513
Eric Smitha73fbe72008-02-23 03:09:44 +00003514- Added the future_builtins module, which contains hex() and oct().
3515 These are the PEP 3127 version of these functions, designed to be
3516 compatible with the hex() and oct() builtins from Python 3.0. They
3517 differ slightly in their output formats from the existing, unchanged
3518 Python 2.6 builtins. The expected usage of the future_builtins
3519 module is:
3520 from future_builtins import hex, oct
3521
Eric Smith7ef40bf2008-02-20 23:34:22 +00003522- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3523 exponents for exponents with absolute value < 100. Follows C99
3524 standard. This is a change on Windows, which would use 3 digits.
3525 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3526 so that any alterations it does to the resulting string will be
3527 available in stringlib/formatter.h (for float.__format__).
3528
Eric Smith5a3c1352008-02-19 13:21:56 +00003529- Implemented PEP 3101, Advanced String Formatting. This adds a new
3530 builtin format(); a format() method for str and unicode; a
3531 __format__() method to object, str, unicode, int, long, float, and
3532 datetime; the class string.Formatter; and the C API
3533 PyObject_Format().
3534
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535- Fixed several potential crashes, all caused by specially crafted
3536 __del__ methods exploiting objects in temporarily inconsistent
3537 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003538
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003539- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540 prevent a possible crash: an Abstract Base Class would try to access
3541 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003542
Georg Brandl3ee81df2008-05-17 18:14:43 +00003543- Fixed repr() and str() of complex numbers with infinity or nan as
3544 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003545
Georg Brandl3ee81df2008-05-17 18:14:43 +00003546- Clear all free lists during a gc.collect() of the highest generation
3547 in order to allow pymalloc to free more arenas. Python may give back
3548 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003549
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Issue #2045: Fix an infinite recursion triggered when printing a
3551 subclass of collections.defaultdict, if its default_factory is set
3552 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003553
Christian Heimesf75dbef2008-02-08 00:11:31 +00003554- Fixed a minor memory leak in dictobject.c. The content of the free
3555 list was not freed on interpreter shutdown.
3556
Georg Brandl3ee81df2008-05-17 18:14:43 +00003557- Limit free list of method and builtin function objects to 256
3558 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003559
Georg Brandl3ee81df2008-05-17 18:14:43 +00003560- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3561 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003562 to compact the internal free lists of pre-allocted ints and floats.
3563
Georg Brandl3ee81df2008-05-17 18:14:43 +00003564- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3565 calls. Python expected the return type int but the fork familie
3566 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003567
Georg Brandl3ee81df2008-05-17 18:14:43 +00003568- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3569 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003570
Georg Brandl3ee81df2008-05-17 18:14:43 +00003571- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3572 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3575 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003576
Georg Brandl3ee81df2008-05-17 18:14:43 +00003577- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3578 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003579
Georg Brandl3ee81df2008-05-17 18:14:43 +00003580- Patch #1473257: generator objects gain a gi_code attribute. This is
3581 the same object as the func_code attribute of the function that
3582 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003583
Georg Brandl3ee81df2008-05-17 18:14:43 +00003584- Issue #1920: "while 0" statements were completely removed by the
3585 compiler, even in the presence of an "else" clause, which is
3586 supposed to be run when the condition is false. Now the compiler
3587 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003588
Guido van Rossumeead05f2008-01-24 18:21:02 +00003589- A few crashers fixed: weakref_in_del.py (issue #1377858);
3590 loosing_dict_ref.py (issue #1303614, test67.py);
3591 borrowed_ref_[34].py (not in tracker).
3592
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003593- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003594 suppressed while an extension is loaded by calling SetErrorMode in
3595 dynload_win.c. The error is still reported properly.
3596
Georg Brandl3ee81df2008-05-17 18:14:43 +00003597- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003598 several extension methods and modules do not work without unicode
3599 support.
3600
Georg Brandl26543b12008-01-21 18:36:51 +00003601- Issue #1882: when compiling code from a string, encoding cookies in the
3602 second line of code were not always recognized correctly.
3603
Georg Brandl14404b62008-01-19 19:27:05 +00003604- Issue #1679: "0x" was taken as a valid integer literal.
3605
Georg Brandl6caad7d2008-01-26 14:19:22 +00003606- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003607 added.
3608
Christian Heimesc94e2b52008-01-14 04:13:37 +00003609- sys.float_info / PyFloat_GetInfo: The floating point information
3610 object was converted from a dict to a specialized structseq object.
3611
Georg Brandl3ee81df2008-05-17 18:14:43 +00003612- Patch #1816: Added sys.flags structseq. It exposes the status of
3613 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003614
Georg Brandl3ee81df2008-05-17 18:14:43 +00003615- Objects/structseq.c: Implemented new structseq representation. The
3616 patch makes structseqs (e.g. the return value of os.stat) more
3617 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003618
Georg Brandl3ee81df2008-05-17 18:14:43 +00003619- Patch #1700288: added a type attribute cache that caches method
3620 accesses, resulting in speedups in heavily object-oriented code.

3628 envvar and sys.dont_write_bytecode attribute. All these can be set
3629 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003630
Georg Brandl3ee81df2008-05-17 18:14:43 +00003631- Improve some exception messages when Windows fails to load an
3632 extension module. Now we get for example '%1 is not a valid Win32
3633 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003634

3638 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003639
Christian Heimes0a8143f2007-12-18 23:22:54 +00003640- Issue #1635: Platform independent creation and representation of NaN

Georg Brandl3ee81df2008-05-17 18:14:43 +00003644- Compiler now generates simpler and faster code for dictionary
3645 literals. The oparg for BUILD_MAP now indicates an estimated
3646 dictionary size. There is a new opcode, STORE_MAP, for adding
3647 entries to the dictionary.

Raymond Hettinger8f669372007-10-03 21:18:11 +00003694
Georg Brandl3ee81df2008-05-17 18:14:43 +00003695- Issue #1686386: Tuple's tp_repr did not take into account the
3696 possibility of having a self-referential tuple, which is possible
3697 from C code. Nor did object's tp_str consider that a type's tp_str
3698 could do something that could lead to an inifinite recursion.
3699 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3700 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003716 PyObject_Call() never calling back out to Python code to trigger
3717 recursion depth updates/checks. Required the creation of a static

3767
Guido van Rossum143b5642007-03-23 04:58:42 +00003768- Bug #1683368: The object.__init__() and object.__new__() methods are
3769 now stricter in rejecting excess arguments. The only time when
3770 either allows excess arguments is when it is not overridden and the
3771 other one is. For backwards compatibility, when both are
3772 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003773 warning later). Also, type.__init__() insists on the same signature
3774 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003776- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3777 object to complex using its __complex__() method before falling back
3778 to the __float__() method. Therefore, the functions in the cmath
3779 module now can operate on objects that define a __complex__()
3780 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003798- Bug #1678647: write a newline after printing an exception in any
3799 case, even when converting the value to a string failed.
3800
Georg Brandl871f1bc2007-03-12 13:17:36 +00003801- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802 its argument, if it exists. If not, it will work like before. This
3803 allows customizing the output of dir() in the presence of a
3804 __getattr__().

3814 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003815
Georg Brandlaa2321b2007-03-07 00:40:28 +00003816- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003817 makes the filenames the warning module prints much more sensible
3818 when a PYTHONSTARTUP file is used.

3833
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004387- Patch #1530482: add pydoc.render_doc() which returns the

4402
Georg Brandl92a6bae2007-03-13 17:43:32 +00004403- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004404 are set for invalid interpolation sequences that would lead to
4405 errors on reading back those values.

4461 TestCase and TestSuite subclasses (not instances) are no longer
4462 accepted in TestSuite.addTest(). This should cause no
4463 incompatibility since it never made sense with ordinary subclasses
4464 -- the failure just occurred later, with a more cumbersome
4465 exception.

4749 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004750
Georg Brandl3ee81df2008-05-17 18:14:43 +00004751- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004752 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004754 does not claim to support starttls. Adds the
4755 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00004854 time so that opening a database previously created with the DB_DUP
4855 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4856 opens. Specifically: dictionary assignment to a DB object will
4857 replace all values for a given key when the database allows
4858 duplicate values. DB users should use DB.put(k, v) when they want

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005138- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005139 periodic threadstate and signal checking in tight loops. By
5140 default, this option is turned-off. It should only be enabled in
5141 debugged, performance critical applications.

5193
Georg Brandl3ee81df2008-05-17 18:14:43 +00005194- Unified naming convention for free lists and their limits. All free
5195 lists in Object/ are named ``free_list``, the counter ``numfree``
5196 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5197 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005198
Georg Brandl3ee81df2008-05-17 18:14:43 +00005199- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5200 to ``PyTuple_SetItem``, it can be used to populate a brand new

5213
Georg Brandl3ee81df2008-05-17 18:14:43 +00005214- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5215 of w# format code incorrectly truncated the length to an int, even
5216 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5217 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005218

5245 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005246
Georg Brandl3ee81df2008-05-17 18:14:43 +00005247- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5248 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005249
Georg Brandl3ee81df2008-05-17 18:14:43 +00005250- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005275- Removed the macfs module. It had been deprecated since Python 2.5.
5276 This lead to the deprecation of macostools.touched() as it relied
