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 Pitrouf3fa0742010-01-31 22:26:04 +000058- Issue #6939: Fix file I/O objects in the `io` module to keep the original
59 file position when calling `truncate()`. It would previously change the
60 file position to the given argument, which goes against the tradition of
61 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
62
Benjamin Petersone06f7112010-01-28 02:15:02 +000063- UserDict is now a new-style class.
64
Antoine Pitrou94c33eb2010-01-27 20:59:50 +000065- Issue #7610: Reworked implementation of the internal
66 :class:`zipfile.ZipExtFile` class used to represent files stored inside
67 an archive. The new implementation is significantly faster and can
68 be wrapped in a :class:`io.BufferedReader` object for more speedups.
69 It also solves an issue where interleaved calls to `read()` and
70 `readline()` give wrong results. Patch by Nir Aides.

77 the release file is empty.
78
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +000079- Issue #7748: Since unicode values are supported for some metadata options
80 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
81 encoded string for them. This ensure that the upload and register commands
82 send the right values to PyPI without any error.
83
R. David Murrayed44dfa2010-01-16 05:15:17 +000084- Issue #1670765: Prevent email.generator.Generator from re-wrapping
85 headers in multipart/signed MIME parts, which fixes one of the sources of
86 invalid modifications to such parts by Generator.
87
Antoine Pitrouc391ad02010-01-15 00:18:00 +000088- Issue #7701: Fix crash in binascii.b2a_uu() in debug mode when given a

103
Tarek Ziadédc0f4872010-01-11 22:50:29 +0000104- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since
105 Extension extra options may change the output without changing the .c
106 file). Initial patch by Collin Winter.
107

130-----------
131
132- iobench (a file I/O benchmark) and ccbench (a concurrency benchmark) were
133 added to the `Tools/` directory. They were previously living in the

Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000143What's New in Python 2.7 alpha 2?
144=================================
145
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +0000146*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000147
148Core and Builtins
149-----------------
150
Benjamin Petersonecdae192010-01-04 00:43:01 +0000151- The __complex__ method is now looked up on the class of instances to make it
152 consistent with other special methods.
153
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000154- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
155 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
156
Mark Dickinson1b34d252010-01-01 17:27:30 +0000157- Issue #5080: A number of functions and methods previously produced a
158 DeprecationWarning when passed a float argument where an integer was
159 expected. These functions and methods now raise TypeError instead.
160 The majority of the effects of this change are in the extension
161 modules, but some core functions and methods are affected: notably
162 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
163 methods.
164
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000165- Issue #7604: Deleting an unset slotted attribute did not raise an
166 AttributeError.

173
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000174- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
175 used to drop the time part of the result.
176
Mark Dickinson46572832009-12-27 14:55:57 +0000177- Issue #1811: improve accuracy and cross-platform consistency for
178 true division of integers: the result of a/b is now correctly
179 rounded for ints a and b (at least on IEEE 754 platforms), and in
180 particular does not depend on the internal representation of a long.
181
Ezio Melottif84caf42009-12-24 22:25:17 +0000182- Issue #6108: unicode(exception) and str(exception) should return the same
183 message when only __str__ (and not __unicode__) is overridden in the subclass.
184
Ronald Oussoren92919a62009-12-24 13:30:58 +0000185- Issue #6834: replace the implementation for the 'python' and 'pythonw'
186 executables on OSX.
187
188 These executables now work properly with the arch(1) command:
189 ``arch -ppc python`` will start a universal binary version of python
190 in PPC mode (unlike previous releases).
191
R. David Murray0a0a1a82009-12-14 16:28:26 +0000192- Issue #1680159: unicode coercion during an 'in' operation no longer masks
193 the underlying error when the coercion fails for the left hand operand.
194
Benjamin Peterson4895af42009-12-13 16:36:53 +0000195- Issue #7491: Metaclass's __cmp__ method was ignored.
196
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000197- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +0000198 in the middle of populating a tuple. Patch by Florent Xicluna.

211 by Arfrever.
212
Antoine Pitrou80157252010-01-08 19:20:17 +0000213- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
214 renaming of `cPickle` to `pickle`. The warning was annoying since there's
215 no alternative to cPickle if you care about performance. Patch by Florent
216 Xicluna.
217

243 the Distutils upload command to avoid an error when PyPI reads it.
244 This occurs on long passwords. Initial patch by JP St. Pierre.
245
246- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000247 Patch by Tatsuhiro Tsujikawa.
248
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000249- Issue #7349: Make methods of file objects in the io module accept None as an
250 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
251 the same as passing no argument.
252
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000253- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

277 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
278 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
279 arguments for integer format codes (other than 'L'): previously an
280 attempt to pass a float resulted in a DeprecationWarning; now it
281 gives a TypeError. For the 'L' format code (which previously had no
282 warning) there is now a DeprecationWarning.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000327- Issue #7419: setlocale() could crash the interpreter on Windows when called
328 with invalid values.
329
Eric Smithc4ab8332009-11-29 17:40:57 +0000330- Issue #3382: 'F' formatting for float and complex now convert the
331 result to upper case. This only affects 'inf' and 'nan', since 'f'
332 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000333
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000334- Remove switch from "%f" formatting to "%g" formatting for floats
335 larger than 1e50 in absolute value.
336
Mark Dickinson18cfada2009-11-23 18:46:41 +0000337- Remove restrictions on precision when formatting floats. E.g.,
338 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
339 requested 120 significant digits instead.
340
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000341- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000345- Issue #7085: Fix crash when importing some extensions in a thread
346 on MacOSX 10.6.
347
Mark Dickinsonb678de82009-11-19 18:41:49 +0000348- Issue #7117: repr(x) for a float x returns a result based on the
349 shortest decimal string that's guaranteed to round back to x under
350 correct rounding (with round-half-to-even rounding mode).
351 Previously it gave a string based on rounding x to 17 decimal digits.
352 repr(x) for a complex number behaves similarly. On platforms where
353 the correctly-rounded strtod and dtoa code is not supported (see below),
354 repr is unchanged.
355
356- Issue #7117: On almost all platforms: float-to-string and
357 string-to-float conversions within Python are now correctly rounded.
358 Places these conversions occur include: str for floats and complex
359 numbers; the float and complex constructors; old-style and new-style
360 numeric formatting; serialization and deserialization of floats and
361 complex numbers using marshal, pickle and json; parsing of float and
362 imaginary literals in Python code; Decimal-to-float conversion.
363
364 The conversions use a Python-adapted version of David Gay's
365 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
366 functions. This code is supported on Windows, and on Unix-like
367 platforms using gcc, icc or suncc as the C compiler. There may be a
368 small number of platforms on which correct operation of this code
369 cannot be guaranteed, so the code is not used: notably, this applies
370 to platforms where the C double format is not IEEE 754 binary64, and
371 to platforms on x86 hardware where the x87 FPU is set to 64-bit
372 precision and Python's configure script is unable to determine how
373 to change the FPU precision. On these platforms conversions use the
374 platform strtod and dtoa, as before.
375
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000376- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000377 now uses the correctly-rounded string <-> float conversions
378 described above (when available), and so produces correctly rounded
379 results that will display nicely under the float repr. There are
380 two related small changes: (1) round now accepts any class with an
381 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000382 floats for the second argument), and (2) an excessively large second
383 integer argument (e.g., round(1.234, 10**100)) no longer raises an
384 exception.
385

513 statement and correctly lookup the __enter__ and __exit__ special methods.
514
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000515- Issue #5829: complex("1e500") no longer raises OverflowError. This

527 (1) inf and nan strings with trailing whitespace were incorrectly
528 rejected; (2) parsing of strings representing infinities and nans
529 was locale aware; and (3) the interpretation of fromhex('-nan')
530 didn't match that of float('-nan').
531
Eric Smitha985a3a2009-05-05 18:26:08 +0000532- Issue #5920: For float.__format__, change the behavior with the
533 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
534 to be like 'g' but with at least one decimal point and with a
535 default precision of 12. Previously, the behavior the same but with
536 a default precision of 6. This more closely matches str(), and
537 reduces surprises when adding alignment flags to the empty
538 presentation type. This also affects the new complex.__format__ in
539 the same way.

Mark Dickinsonefc82f72009-03-20 15:51:55 +0000612- Issue #4258: Make it possible to use base 2**30 instead of base
613 2**15 for the internal representation of integers, for performance
614 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
615 --enable-big-digits option to configure, which overrides the
616 default. Add sys.long_info structseq to provide information about
617 the internal format.
618
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000619- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

625
Eric Smith6f42edb2009-03-14 11:57:26 +0000626- Issue #5237: Allow auto-numbered fields in str.format(). For

628
Brett Cannon6c4cff02009-03-11 04:51:06 +0000629- Issue #3652: Make the 'line' argument for warnings.showwarning() a

631
Eric Smithe9fb6862009-02-20 14:02:36 +0000632- Issue #5247: Improve error message when unknown format codes are

634 float arguments.
635
Raymond Hettinger08259e82009-02-18 23:10:19 +0000636- Running Python with the -3 option now also warns about classic division
637 for ints and longs.
638
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000639- Issue #5260: Long integers now consume less memory: average
640 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
641 on a 64-bit system.
642
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000643- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

648
Benjamin Petersone18ef192009-01-20 14:21:16 +0000649- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
650
Georg Brandl29c6a282009-04-05 20:23:13 +0000651- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000652 were suppressing all exceptions. These include list(), filter(), map(),
653 zip(), and bytearray().
654
Benjamin Peterson596d3062009-01-19 15:42:23 +0000655- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitrouc2f02212009-01-13 23:13:52 +0000663- Issue #4935: The overflow checking code in the expandtabs() method common
664 to str, bytes and bytearray could be optimized away by the compiler, letting
665 the interpreter segfault instead of raising an error.
666
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000667- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000674- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
675 collecting the oldest generation) so that allocating lots of objects without
676 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000677 Martin von Löwis at

681
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000682- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
683 an existing .py counterpart, override the co_filename attributes of all
684 code objects if the original filename is obsolete (which can happen if the
685 file has been renamed, moved, or if it is accessed through different paths).
686 Patch by Ziga Seilnacht and Jean-Paul Calderone.
687
Martin v. Löwis5344c992009-01-02 20:32:55 +0000688- Issue #4075: Use OutputDebugStringW in Py_FatalError.

692
Antoine Pitrouaa687902009-01-01 14:11:22 +0000693- Issue #3680: Reference cycles created through a dict, set or deque iterator

695
Nick Coghlan180e4002008-12-30 01:18:48 +0000696- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
697 where the tp_hash and tp_dict slots are both NULL.
698
Benjamin Peterson7af65562008-12-29 17:56:58 +0000699- Issue #4764: With io.open, IOError.filename is set when trying to open a

706 bytearray.translate(). It was always allowed for bytes.translate().
707
Skip Montanarof205c132008-12-23 03:30:15 +0000708- Added test case to ensure attempts to read from a file opened for writing
709 fail.
710

722
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000723- Issue #4597: Fixed several opcodes that weren't always propagating
724 exceptions.
725
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000726- Issue #4445: Replace "sizeof(PyStringObject)" with
727 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
728 str instances. On a typical machine this saves 3 bytes of memory
729 (on average) per string allocation.
730
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000731- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
732 interpreter to abort ("Fatal Python error: Could not reset the stack!")
733 instead of throwing a MemoryError.
734
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000735- Issue #3689: The list reversed iterator now supports __length_hint__
736 instead of __len__. Behavior now matches other reversed iterators.
737
Benjamin Petersonc078f922008-11-21 22:27:24 +0000738- Issue #4367: Python would segfault during compiling when the unicodedata
739 module couldn't be imported and \N escapes were present.
740
Vinay Sajip213faca2008-12-03 23:22:58 +0000741- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000742 method on file objects with closefd=False. The file descriptor is still
743 kept open but the file object behaves like a closed file. The ``FileIO``
744 object also got a new readonly attribute ``closefd``.
745
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000746- Issue #4348: Some bytearray methods returned that didn't cause any change to
747 the bytearray, returned the same bytearray instead of a copy.
748
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000749- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
750

754
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000755- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

757
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000758- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
759 method does not return iterators for the 4th and 5th items.
760
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000761- Issue #4209: Enabling unicode_literals and the print_function in the same
762 __future__ import didn't work.
763
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000764- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000765 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000766
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000767- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
768 returned a path longer than MAX_PATH. (But It's doubtful this code path is
769 really executed because I cannot move to such directory on win2k)
770
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000771- Issue #4069: When set.remove(element) is used with a set element, the element
772 is temporarily replaced with an equivalent frozenset. But the eventual
773 KeyError would always report the empty frozenset([]) as the missing key. Now
774 it correctly refers to the initial element.
775
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000776- Issue #4509: Various issues surrounding resize of bytearray objects to
777 which there are buffer exports.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000791- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
792 returned them on 64bit platforms.
793
Walter Dörwalded960ac2009-05-03 22:36:33 +0000794- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
795 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
796 step. This avoids problems with counting UTF-8 bytes that ignores the effect
797 of using the replace error handler in PyUnicode_DecodeUTF8().
798
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000799- Issue #3739: The unicode-internal encoder now reports the number of characters
800 consumed like any other encoder (instead of the number of bytes).
801
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000802- Issue #2422: When compiled with the ``--with-valgrind`` option, the
803 pymalloc allocator will be automatically disabled when running under
804 Valgrind. This gives improved memory leak detection when running
805 under Valgrind, while taking advantage of pymalloc at other times.

1988 result in struct.error. Previously an x with an __int__ method
1989 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1990 ,'*i', '*l', and an x with a __long__ method could be packed by
1991 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1992 TypeError used to be raised (with a confusing error message) for
1993 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

2186
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002187- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2188 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2189 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2190 ``printf`` function, whereas PyString_FromFormat has an independent
2191 implementation and uses "%zd" on all platforms for size_t values.
2192 This makes a difference on win64, where ``printf`` needs "%Id" to display
2193 64bit values.

2211
Vinay Sajip35e3b032008-09-01 14:33:59 +00002212- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002213 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2214 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2215 when given a tuple of classes as second argument, were looking up
2216 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2217 type object.

2288 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2289 for catch_warnings() also led to an improvement in the raising of a
2290 DeprecationWarning related to warnings.warn_explicit().
2291

2314
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002315- Issue #2975: When compiling several extension modules with Visual Studio 2008
2316 from the same python interpreter, some environment variables would grow
2317 without limit.
2318
Benjamin Peterson37346b22008-08-23 20:27:43 +00002319- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002356What's New in Python 2.6 beta 3?
2357================================
2358
Barry Warsaw07a4a382008-08-21 01:15:08 +00002359*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002360
2361Core and Builtins
2362-----------------
2363
Guido van Rossumf8402962008-08-20 15:01:50 +00002364- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2365 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2366 extensions do not automatically benefit from the class attribute
2367 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2368 to their tp_flags field if they care. This is a backwards
2369 compatibility feature; in 3.0, all types will use the cache by
2370 default.
2371
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002372- Keyword arguments can now follow starred arguments. (``f(a, *args,
2373 keyword=23)`` is now valid syntax.)
2374
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002375- ctypes function pointers that are COM methods have a boolean True
2376 value again.
2377
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002378- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2379 by denying s# to parse objects that have a releasebuffer procedure,
2380 and introducing s*.
2381
Georg Brandl1e13ea92008-08-11 09:07:59 +00002382- Issue #3537: Fix an assertion failure when an empty but presized dict
2383 object was stored in the freelist.
2384
Mark Dickinsonb6467572008-08-04 21:30:09 +00002385- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2386 ValueError consistently across platforms.
2387
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002388- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2389 (64bit Unix, for example), unichr() would truncate its argument and return
2390 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2391
Neal Norwitze7d8be82008-07-31 17:17:14 +00002392- Apply security patches from Apple.
2393
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002394- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2395 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2396
Antoine Pitrou92f82162008-07-25 22:22:08 +00002397- Issue #1819: function calls with several named parameters are now on
2398 average 35% faster (as measured by pybench).
2399
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002400- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2401 the python debugger steps into a class statement: the free variables (local
2402 variables defined in an outer scope) would be deleted from the outer scope.
2403
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002404- Issue #2620: Overflow checking when allocating or reallocating memory
2405 was not always being done properly in some python types and extension
2406 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2407 all been updated to perform better checks and places in the code that
2408 would previously leak memory on the error path when such an allocation
2409 failed have been fixed.
2410
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002411Library
2412-------
2413

2415
Benjamin Petersone977ad42008-08-20 01:42:01 +00002416- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2417 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2418
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002419- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2420 version reported by these tools does not necessarily follow the python
2421 version numbering scheme, so the module is less strict when parsing it.
2422
Nick Coghlanf70385a2008-08-18 12:42:46 +00002423- Issue #2235: Added Py3k warnings for types which will become unhashable
2424 under the stricter __hash__ inheritance rules in 3.0. Several types
2425 which did not meet the rules for hash invariants and were already
2426 unhashable in 3.0 have now been explicitly flagged as unhashable in
2427 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2428 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2429
Brett Cannon88f801d2008-08-18 00:46:22 +00002430- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2434
Brett Cannon46225e72008-08-18 00:36:52 +00002435- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2438
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002439- Issue #3575: Incremental decoder's decode function now takes bytearray
2440 by using 's*' instead of 't#'.
2441
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002442- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002443 fails unicode conversion on 2nd parameter. (windows only)
2444
Facundo Batista94f243a2008-08-17 03:38:39 +00002445- Issue 2464. urllib2 now supports a malformation in the URL received
2446 in a redirect.
2447
Brett Cannonabe423e2008-08-16 21:47:07 +00002448- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002449 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002450
Facundo Batistaeb90b782008-08-16 14:44:07 +00002451- Issue #2776: fixed small issue when handling an URL with double slash
2452 after a 302 response in the case of not going through a proxy.
2453
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002454- Issue #2676: in the email package, content-type parsing was hanging on
2455 pathological input because of quadratic or exponential behaviour of a
2456 regular expression.
2457
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002458- Issue #3476: binary buffered reading through the new "io" library is now
2459 thread-safe.
2460
Brett Cannonbf3157b2008-08-14 05:00:03 +00002461- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2462 since mimetools itself is deprecated. Because modules are cached, all
2463 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2464
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002465- Issue #3134: shutil referenced undefined WindowsError symbol.
2466
Robert Schuppenies14646332008-08-10 11:01:53 +00002467- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2468 menu entries were not deleted.
2469
Brett Cannon83e81842008-08-09 23:30:55 +00002470- Copied the implementation of reduce() to _functools.reduce() to have a
2471 version that did not raise a DeprecationWarning under -3.
2472
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002473- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2474 a MemoryError rather than silently stop the iteration.
2475
Guido van Rossum59ce9012008-08-09 14:55:34 +00002476- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2477 to _sre.compile() will now be rejected. This should not affect anybody
2478 since the re.compile() function never generates invalid re-bytecode.
2479
Skip Montanaroa032bf42008-08-08 22:52:51 +00002480- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

2485 the reload() built-in has been removed.
2486
Brett Cannon7e30b672008-08-04 21:52:25 +00002487- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002488 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002499 asking for a specific length. This problem only affected files opened
2500 using the new "io" module, not the built-in open() function.

2527 mode 0600 rather than 000 under Unix.
2528
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002529- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2530 argument in python 2.5, this broke code that subclassed Popen to include its

2560 an integer using operator.index().
2561
Mark Dickinson64b7e502008-07-16 09:40:03 +00002562- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2563 produced a ValueError instead of giving the correct float.
2564
Eric Smitha5fa5a22008-07-16 00:11:49 +00002565- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2566 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2567
Mark Dickinson7103aa42008-07-15 19:08:33 +00002568- Issue #3008: the float type has a new instance method 'float.hex'

Nick Coghlan6d6bd442008-07-15 15:40:22 +00002572- Issue #2235: __hash__ is once again inherited by default. To allow
2573 collections.Hashable to remain meaningful in the presence of the
2574 default hash implementation (object.__hash__), it is now possible
2575 to explicit block inheritance of hash by setting __hash__=None at
2576 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2577 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00002579- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2580 the parent module cannot be found while performing an absolute import.
2581 This means that an incorrectly defined __package__ attribute will
2582 now only prevent relative imports in that module rather than causing
2583 all imports from that module to fail.

2596
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002597- Issue #3004: Minor change to slice.indices(): the start and stop
2598 arguments are now treated identically, making the behaviour easier
2599 to describe and understand. For example, slice(None, -10,
2600 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2601 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2602 10, -1).

2645 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002646 wrong because the actual transmitted size could differ from the

Georg Brandl5cc774e2008-06-11 20:28:06 +00003056 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003057
3058 This is controlled by the configure argument ``--with-universal-archs``:

3061
3062 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3063
3064 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

3105 two handlers that derive the same default base class.

Christian Heimese74c8f22008-04-19 02:23:57 +00003107- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003118- Issue #1631171: Re-implement the 'warnings' module in C (the
3119 original Python code has been kept as backup). This will allow for
3120 using the 'warning's machinery in such places as the parser where
3121 use of pure Python code is not possible. Both the ``showarning()``
3122 and ``formatwarning()`` gain an optional 'line' argument which is
3123 not called by default for backwards-compatibility reasons. Setting
3124 ``warnings.showwarning()`` to an implementation that lacks support

Georg Brandl3ee81df2008-05-17 18:14:43 +00003188- Issue #2550: The approach used by client/server code for obtaining
3189 ports to listen on in network-oriented tests has been refined in an
3190 effort to facilitate running multiple instances of the entire
3191 regression test suite in parallel without issue.
3192 test_support.bind_port() has been fixed such that it will always
3193 return a unique port -- which wasn't always the case with the
3194 previous implementation, especially if socket options had been set
3195 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3196 new implementation of bind_port() will actually raise an exception
3197 if it is passed an AF_INET/SOCK_STREAM socket with either the
3198 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3199 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3200 the socket it's been passed. This currently only applies to
3201 Windows. This option prevents any other sockets from binding to the
3202 host/port we've bound to, thus removing the possibility of the
3203 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3204 when a second SOCK_STREAM socket binds and accepts to a host/port
3205 that's already been bound by another socket. The optional preferred
3206 port parameter to bind_port() has been removed. Under no
3207 circumstances should tests be hard coding ports!
3208
3209 test_support.find_unused_port() has also been introduced, which will
3210 pass a temporary socket object to bind_port() in order to obtain an
3211 unused port. The temporary socket object is then closed and
3212 deleted, and the port is returned. This method should only be used
3213 for obtaining an unused port in order to pass to an external program
3214 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3215 a parameter to a server-oriented class that doesn't give you direct
3216 access to the underlying socket used.
3217
3218 Finally, test_support.HOST has been introduced, which should be used
3219 for the host argument of any relevant socket calls (i.e. bind and
3220 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003221
3222 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003223 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003224 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3225 test_asynchat and test_socket_ssl.
3226
Georg Brandl3ee81df2008-05-17 18:14:43 +00003227 It is now possible for multiple instances of the regression test
3228 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003394- Issue #1202: zlib.crc32 and zlib.adler32 no longer return different
3395 values on 32-bit vs. 64-bit python interpreters. Both were correct,
3396 but they now both return a signed integer object for consistency.

3495-----------------
3496
Fred Drakea8ee94b2008-03-01 02:45:07 +00003497- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003498 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003499
Georg Brandlad61bc82008-02-23 15:11:18 +00003500- Issue #2067: file.__exit__() now calls subclasses' close() method.
3501
3502- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003503
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003504- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003505 issue 215555 for a discussion.
3506
Eric Smitha73fbe72008-02-23 03:09:44 +00003507- Added the future_builtins module, which contains hex() and oct().
3508 These are the PEP 3127 version of these functions, designed to be
3509 compatible with the hex() and oct() builtins from Python 3.0. They
3510 differ slightly in their output formats from the existing, unchanged
3511 Python 2.6 builtins. The expected usage of the future_builtins
3512 module is:
3513 from future_builtins import hex, oct
3514
Eric Smith7ef40bf2008-02-20 23:34:22 +00003515- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3516 exponents for exponents with absolute value < 100. Follows C99
3517 standard. This is a change on Windows, which would use 3 digits.
3518 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3519 so that any alterations it does to the resulting string will be
3520 available in stringlib/formatter.h (for float.__format__).
3521
Eric Smith5a3c1352008-02-19 13:21:56 +00003522- Implemented PEP 3101, Advanced String Formatting. This adds a new
3523 builtin format(); a format() method for str and unicode; a
3524 __format__() method to object, str, unicode, int, long, float, and
3525 datetime; the class string.Formatter; and the C API
3526 PyObject_Format().
3527
Georg Brandl3ee81df2008-05-17 18:14:43 +00003528- Fixed several potential crashes, all caused by specially crafted
3529 __del__ methods exploiting objects in temporarily inconsistent
3530 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003531
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003532- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003533 prevent a possible crash: an Abstract Base Class would try to access
3534 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003535
Georg Brandl3ee81df2008-05-17 18:14:43 +00003536- Fixed repr() and str() of complex numbers with infinity or nan as
3537 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003538
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539- Clear all free lists during a gc.collect() of the highest generation
3540 in order to allow pymalloc to free more arenas. Python may give back
3541 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003542
Georg Brandl3ee81df2008-05-17 18:14:43 +00003543- Issue #2045: Fix an infinite recursion triggered when printing a
3544 subclass of collections.defaultdict, if its default_factory is set
3545 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003546
Christian Heimesf75dbef2008-02-08 00:11:31 +00003547- Fixed a minor memory leak in dictobject.c. The content of the free
3548 list was not freed on interpreter shutdown.
3549
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Limit free list of method and builtin function objects to 256
3551 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003552
Georg Brandl3ee81df2008-05-17 18:14:43 +00003553- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3554 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003555 to compact the internal free lists of pre-allocted ints and floats.
3556
Georg Brandl3ee81df2008-05-17 18:14:43 +00003557- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3558 calls. Python expected the return type int but the fork familie
3559 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003560
Georg Brandl3ee81df2008-05-17 18:14:43 +00003561- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3562 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003563
Georg Brandl3ee81df2008-05-17 18:14:43 +00003564- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3565 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003570- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3571 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003572
Georg Brandl3ee81df2008-05-17 18:14:43 +00003573- Patch #1473257: generator objects gain a gi_code attribute. This is
3574 the same object as the func_code attribute of the function that
3575 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003576
Georg Brandl3ee81df2008-05-17 18:14:43 +00003577- Issue #1920: "while 0" statements were completely removed by the
3578 compiler, even in the presence of an "else" clause, which is
3579 supposed to be run when the condition is false. Now the compiler
3580 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003581
Guido van Rossumeead05f2008-01-24 18:21:02 +00003582- A few crashers fixed: weakref_in_del.py (issue #1377858);
3583 loosing_dict_ref.py (issue #1303614, test67.py);
3584 borrowed_ref_[34].py (not in tracker).
3585
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003586- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003587 suppressed while an extension is loaded by calling SetErrorMode in
3588 dynload_win.c. The error is still reported properly.
3589
Georg Brandl3ee81df2008-05-17 18:14:43 +00003590- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003591 several extension methods and modules do not work without unicode
3592 support.
3593
Georg Brandl26543b12008-01-21 18:36:51 +00003594- Issue #1882: when compiling code from a string, encoding cookies in the
3595 second line of code were not always recognized correctly.
3596
Georg Brandl14404b62008-01-19 19:27:05 +00003597- Issue #1679: "0x" was taken as a valid integer literal.
3598
Georg Brandl6caad7d2008-01-26 14:19:22 +00003599- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003600 added.
3601
Christian Heimesc94e2b52008-01-14 04:13:37 +00003602- sys.float_info / PyFloat_GetInfo: The floating point information
3603 object was converted from a dict to a specialized structseq object.
3604
Georg Brandl3ee81df2008-05-17 18:14:43 +00003605- Patch #1816: Added sys.flags structseq. It exposes the status of
3606 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003607
Georg Brandl3ee81df2008-05-17 18:14:43 +00003608- Objects/structseq.c: Implemented new structseq representation. The
3609 patch makes structseqs (e.g. the return value of os.stat) more
3610 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003611
Georg Brandl3ee81df2008-05-17 18:14:43 +00003612- Patch #1700288: added a type attribute cache that caches method
3613 accesses, resulting in speedups in heavily object-oriented code.

3621 envvar and sys.dont_write_bytecode attribute. All these can be set
3622 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003623
Georg Brandl3ee81df2008-05-17 18:14:43 +00003624- Improve some exception messages when Windows fails to load an
3625 extension module. Now we get for example '%1 is not a valid Win32
3626 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003627

3631 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003632
Christian Heimes0a8143f2007-12-18 23:22:54 +00003633- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003634 and INF. float("nan"), float("inf") and float("-inf") now work on
3635 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003636
Georg Brandl3ee81df2008-05-17 18:14:43 +00003637- Compiler now generates simpler and faster code for dictionary
3638 literals. The oparg for BUILD_MAP now indicates an estimated
3639 dictionary size. There is a new opcode, STORE_MAP, for adding
3640 entries to the dictionary.

3683
Georg Brandl3ee81df2008-05-17 18:14:43 +00003684- The enumerate() builtin function is no longer bounded to sequences
3685 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3686 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003687
Georg Brandl3ee81df2008-05-17 18:14:43 +00003688- Issue #1686386: Tuple's tp_repr did not take into account the
3689 possibility of having a self-referential tuple, which is possible
3690 from C code. Nor did object's tp_str consider that a type's tp_str
3691 could do something that could lead to an inifinite recursion.
3692 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3693 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003695- Issue #1164: It was possible to trigger deadlock when using the
3696 'print' statement to write to a file since the GIL was not released
3697 as needed. Now PyObject_Print() does the right thing along with
3698 various tp_print implementations of the built-in types and those in
3699 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00003708- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003709 PyObject_Call() never calling back out to Python code to trigger
3710 recursion depth updates/checks. Required the creation of a static

Georg Brandl3ee81df2008-05-17 18:14:43 +00003729 __*__ attributes. (Some already existed, e.g., __doc__ and
3730 __name__.)

3737
Collin Winter62903052007-05-18 23:11:24 +00003738- except clauses may now be spelled either "except E, target:" or

3740 with Python 3.0.

3760
Guido van Rossum143b5642007-03-23 04:58:42 +00003761- Bug #1683368: The object.__init__() and object.__new__() methods are
3762 now stricter in rejecting excess arguments. The only time when
3763 either allows excess arguments is when it is not overridden and the
3764 other one is. For backwards compatibility, when both are
3765 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003766 warning later). Also, type.__init__() insists on the same signature
3767 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003769- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3770 object to complex using its __complex__() method before falling back
3771 to the __float__() method. Therefore, the functions in the cmath
3772 module now can operate on objects that define a __complex__()
3773 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00003791- Bug #1678647: write a newline after printing an exception in any
3792 case, even when converting the value to a string failed.
3793
Georg Brandl871f1bc2007-03-12 13:17:36 +00003794- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003795 its argument, if it exists. If not, it will work like before. This
3796 allows customizing the output of dir() in the presence of a
3797 __getattr__().

3807 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003808
Georg Brandlaa2321b2007-03-07 00:40:28 +00003809- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003810 makes the filenames the warning module prints much more sensible
3811 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003824- Patch #1674228: when assigning a slice (old-style), check for the
3825 sq_ass_slice instead of the sq_slice slot.
3826
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827- When printing an unraisable error, don't print exceptions. before

4395
Georg Brandl92a6bae2007-03-13 17:43:32 +00004396- Patch #1603688: ConfigParser.SafeConfigParser now checks values that

4454 TestCase and TestSuite subclasses (not instances) are no longer
4455 accepted in TestSuite.addTest(). This should cause no
4456 incompatibility since it never made sense with ordinary subclasses

4741 obtained from the TLS negotiation itself. Patch contributed by Bill
4742 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004743
Georg Brandl3ee81df2008-05-17 18:14:43 +00004744- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004745 that the SMTP.starttls() caller no longer needs to call ehlo()
4746 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004747 does not claim to support starttls. Adds the
4748 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Raymond Hettinger12e94202007-11-07 01:13:09 +00004832

Georg Brandl3ee81df2008-05-17 18:14:43 +00004847 time so that opening a database previously created with the DB_DUP
4848 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4849 opens. Specifically: dictionary assignment to a DB object will
4850 replace all values for a given key when the database allows
4851 duplicate values. DB users should use DB.put(k, v) when they want
4852 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004853

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005131- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00005132 periodic threadstate and signal checking in tight loops. By
5133 default, this option is turned-off. It should only be enabled in
5134 debugged, performance critical applications.
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00005135

5185-----
5186
Georg Brandl3ee81df2008-05-17 18:14:43 +00005187- Unified naming convention for free lists and their limits. All free
5188 lists in Object/ are named ``free_list``, the counter ``numfree``
5189 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5190 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005191
Georg Brandl3ee81df2008-05-17 18:14:43 +00005192- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5193 to ``PyTuple_SetItem``, it can be used to populate a brand new
5194 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005195

5203
5204- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5205 ``PyFloat_GetInfo()`` to the float API.
5206
Georg Brandl3ee81df2008-05-17 18:14:43 +00005207- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5208 of w# format code incorrectly truncated the length to an int, even
5209 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5210 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005211
Georg Brandl3ee81df2008-05-17 18:14:43 +00005212- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

5230- Fix some leftovers from the conversion from int to Py_ssize_t
5231 (relevant to strings and sequences of more than 2**31 items).
5232
5233- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5234 outside of pystate.c and should not be necessary.
5235
Georg Brandl3ee81df2008-05-17 18:14:43 +00005236- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5237 absolute imports. In earlier versions they might have used relative
5238 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005239
Georg Brandl3ee81df2008-05-17 18:14:43 +00005240- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5241 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005242
Georg Brandl3ee81df2008-05-17 18:14:43 +00005243- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005268- Removed the macfs module. It had been deprecated since Python 2.5.
5269 This lead to the deprecation of macostools.touched() as it relied
5270 solely on macfs and was a no-op under OS X.
