Benjamin Peterson4f51baf2009-12-05 18:40:02 +00007What's New in Python 2.7 alpha 2?
8=================================
9
10*Release date: XXXX-XX-XX*
11
12Core and Builtins
13-----------------
14
Benjamin Petersonecdae192010-01-04 00:43:01 +000015- The __complex__ method is now looked up on the class of instances to make it
16 consistent with other special methods.
17
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000018- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
19 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
20
Mark Dickinson1b34d252010-01-01 17:27:30 +000021- Issue #5080: A number of functions and methods previously produced a
22 DeprecationWarning when passed a float argument where an integer was
23 expected. These functions and methods now raise TypeError instead.
24 The majority of the effects of this change are in the extension
25 modules, but some core functions and methods are affected: notably
26 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
27 methods.
28
Benjamin Peterson0f02d392009-12-30 19:34:10 +000029- Issue #7604: Deleting an unset slotted attribute did not raise an
30 AttributeError.
31
Mark Dickinson99d652e2009-12-30 12:12:23 +000032- Issue #7534: Fix handling of IEEE specials (infinities, nans,
33 negative zero) in ** operator. The behaviour now conforms to that
34 described in C99 Annex F.
35
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000036- Issue #7579: the msvcrt module now has docstrings for all its functions.
37
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000038- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
39 used to drop the time part of the result.
40
Mark Dickinson46572832009-12-27 14:55:57 +000041- Issue #1811: improve accuracy and cross-platform consistency for
42 true division of integers: the result of a/b is now correctly
43 rounded for ints a and b (at least on IEEE 754 platforms), and in
44 particular does not depend on the internal representation of a long.
45
Ezio Melottif84caf42009-12-24 22:25:17 +000046- Issue #6108: unicode(exception) and str(exception) should return the same
47 message when only __str__ (and not __unicode__) is overridden in the subclass.
48
Ronald Oussoren92919a62009-12-24 13:30:58 +000049- Issue #6834: replace the implementation for the 'python' and 'pythonw'
50 executables on OSX.
51
52 These executables now work properly with the arch(1) command:
53 ``arch -ppc python`` will start a universal binary version of python
54 in PPC mode (unlike previous releases).
55
R. David Murray0a0a1a82009-12-14 16:28:26 +000056- Issue #1680159: unicode coercion during an 'in' operation no longer masks
57 the underlying error when the coercion fails for the left hand operand.
58
Benjamin Peterson4895af42009-12-13 16:36:53 +000059- Issue #7491: Metaclass's __cmp__ method was ignored.
60
Antoine Pitrou2a08b422009-12-13 16:18:14 +000061- Issue #7466: segmentation fault when the garbage collector is called
62 in the middle of populating a tuple. Patch by Florent Xicluna.
63
R. David Murrayc7298ff2009-12-14 21:57:39 +000064
Benjamin Peterson4f51baf2009-12-05 18:40:02 +000065Library

Antoine Pitrou673ddf92010-01-03 22:29:56 +000068- Issue #7471: Improve the performance of GzipFile's buffering mechanism,
69 and make it implement the `io.BufferedIOBase` ABC to allow for further
70 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
71
72- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +000073 parameter to allow specifying where your connections come from.
74
Gregory P. Smith79a3eb12010-01-03 01:29:44 +000075- socket.create_connection now accepts an optional source_address parameter.
76
Ezio Melotti569e61f2009-12-30 06:14:51 +000077- Issue #5511: now zipfile.ZipFile can be used as a context manager.
78 Initial patch by Brian Curtin.
79
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +000080- Distutils now correctly identifies the build architecture as "x86_64"
Ezio Melotti569e61f2009-12-30 06:14:51 +000081 when building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +000082
Tarek Ziadé0479eb52009-12-21 23:37:44 +000083- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest
84 file in text mode.

87 the Distutils upload command to avoid an error when PyPI reads it.
88 This occurs on long passwords. Initial patch by JP St. Pierre.
89
90- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +000091 Patch by Tatsuhiro Tsujikawa.
92
Benjamin Petersonddd392c2009-12-13 19:19:07 +000093- Issue #7349: Make methods of file objects in the io module accept None as an
94 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
95 the same as passing no argument.
96
Benjamin Petersonc4771d22009-12-13 17:31:31 +000097- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
98 like other file objects.
99
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000100- Issue #7357: tarfile no longer suppresses fatal extraction errors by
101 default.
102
Vinay Sajip5cc4e2a2009-12-11 09:16:01 +0000103- Issue #7470: logging: fix bug in Unicode encoding fallback.

107
Tarek Ziadé2421d562009-12-20 23:23:34 +0000108- Issue #7457: added a read_pkg_file method to
Tarek Ziadéa939ecd2009-12-08 08:56:49 +0000109 distutils.dist.DistributionMetadata.
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000110

116
Mark Dickinson1b34d252010-01-01 17:27:30 +0000117- Issue #5080: The argument parsing functions PyArg_ParseTuple,
118 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
119 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
120 arguments for integer format codes (other than 'L'): previously an
121 attempt to pass a float resulted in a DeprecationWarning; now it
122 gives a TypeError. For the 'L' format code (which previously had no
123 warning) there is now a DeprecationWarning.
124
Georg Brandl740cdc32009-12-28 08:34:58 +0000125- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

Barry Warsaw12582c92008-10-02 03:33:51 +0000160What's New in Python 2.7 alpha 1
161================================
162
Benjamin Peterson3513c872009-12-05 18:48:13 +0000163*Release date: 2009-12-05*
Barry Warsaw12582c92008-10-02 03:33:51 +0000164
165Core and Builtins
166-----------------
167
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000168- Issue #7419: setlocale() could crash the interpreter on Windows when called
169 with invalid values.
170
Eric Smithc4ab8332009-11-29 17:40:57 +0000171- Issue #3382: 'F' formatting for float and complex now convert the
172 result to upper case. This only affects 'inf' and 'nan', since 'f'
173 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000174
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000175- Remove switch from "%f" formatting to "%g" formatting for floats
176 larger than 1e50 in absolute value.
177
Mark Dickinson18cfada2009-11-23 18:46:41 +0000178- Remove restrictions on precision when formatting floats. E.g.,
179 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
180 requested 120 significant digits instead.
181
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000182- Add Py3k warnings for parameter names in parenthesis.
183
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000184- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000185
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000186- Issue #7085: Fix crash when importing some extensions in a thread
187 on MacOSX 10.6.
188
Mark Dickinsonb678de82009-11-19 18:41:49 +0000189- Issue #7117: repr(x) for a float x returns a result based on the
190 shortest decimal string that's guaranteed to round back to x under
191 correct rounding (with round-half-to-even rounding mode).
192 Previously it gave a string based on rounding x to 17 decimal digits.
193 repr(x) for a complex number behaves similarly. On platforms where
194 the correctly-rounded strtod and dtoa code is not supported (see below),
195 repr is unchanged.
196
197- Issue #7117: On almost all platforms: float-to-string and
198 string-to-float conversions within Python are now correctly rounded.
199 Places these conversions occur include: str for floats and complex
200 numbers; the float and complex constructors; old-style and new-style
201 numeric formatting; serialization and deserialization of floats and
202 complex numbers using marshal, pickle and json; parsing of float and
203 imaginary literals in Python code; Decimal-to-float conversion.
204
205 The conversions use a Python-adapted version of David Gay's
206 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
207 functions. This code is supported on Windows, and on Unix-like
208 platforms using gcc, icc or suncc as the C compiler. There may be a
209 small number of platforms on which correct operation of this code
210 cannot be guaranteed, so the code is not used: notably, this applies
211 to platforms where the C double format is not IEEE 754 binary64, and
212 to platforms on x86 hardware where the x87 FPU is set to 64-bit
213 precision and Python's configure script is unable to determine how
214 to change the FPU precision. On these platforms conversions use the
215 platform strtod and dtoa, as before.
216
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000217- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000218 now uses the correctly-rounded string <-> float conversions
219 described above (when available), and so produces correctly rounded
220 results that will display nicely under the float repr. There are
221 two related small changes: (1) round now accepts any class with an
222 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000223 floats for the second argument), and (2) an excessively large second
224 integer argument (e.g., round(1.234, 10**100)) no longer raises an
225 exception.
226
Philip Jenveyfab8be22009-11-17 02:42:26 +0000227- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
228
Benjamin Petersone36199b2009-11-12 23:39:44 +0000229- Fix several issues with compile(). The input can now contain Windows and Mac
230 newlines and is no longer required to end in a newline.
231
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000232- Remove length limitation when constructing a complex number from a
233 unicode string.
234
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000235- Issue #7244: itertools.izip_longest() no longer ignores exceptions
236 raised during the formation of an output tuple.
237

243
Eric Smithc12781a2009-10-19 14:38:14 +0000244- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

249
Benjamin Peterson196b0922009-10-15 15:44:46 +0000250- Issue #7140: The __dict__ of a module should not be cleared unless the module
251 is the only object holding a reference to it.
252
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000253- Issue #1754094: Improve the stack depth calculation in the compiler.

255 Patch by Christopher Tur Lesniewski-Laas.
256

Mark Dickinson2f865b92009-06-30 15:32:30 +0000320- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
321 This fixes a build failure on HP-UX: int32_t and uint32_t are
322 defined in inttypes.h instead of stdint.h on that platform.

335
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000336- When no module is given in a relative import, the module field of the
337 ImportFrom AST node is now None instead of an empty string.
338
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000339- Assignment to None using import statements now raises a SyntaxError.
340
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +0000341- Issue #4547: When debugging a very large function, it was not always
342 possible to update the lineno attribute of the current frame.
343
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000344- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000345 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000346
Raymond Hettinger578a2282009-05-29 04:58:52 +0000347- Issue #5982: staticmethod and classmethod now expose the wrapped
348 function with __func__.
349
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000350- Added support for multiple context managers in the same with-statement.
351 Deprecated contextlib.nested() which is no longer needed.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000353- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
354 statement and correctly lookup the __enter__ and __exit__ special methods.
355
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000356- Issue #5829: complex("1e500") no longer raises OverflowError. This
357 makes it consistent with float("1e500") and interpretation of real
358 and imaginary literals.
359
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000360- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

R. David Murray525cffc2009-05-13 13:07:14 +0000365- Issue #5994: the marshal module now has docstrings.
366
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000367- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
368 (1) inf and nan strings with trailing whitespace were incorrectly
369 rejected; (2) parsing of strings representing infinities and nans
370 was locale aware; and (3) the interpretation of fromhex('-nan')
371 didn't match that of float('-nan').
372
Eric Smitha985a3a2009-05-05 18:26:08 +0000373- Issue #5920: For float.__format__, change the behavior with the
374 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
375 to be like 'g' but with at least one decimal point and with a
376 default precision of 12. Previously, the behavior the same but with
377 a default precision of 6. This more closely matches str(), and
378 reduces surprises when adding alignment flags to the empty
379 presentation type. This also affects the new complex.__format__ in
380 the same way.
381
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000382- Issue #5890: in subclasses of 'property' the __doc__ attribute was
383 shadowed by classtype's, even if it was None. property now
384 inserts the __doc__ into the subclass instance __dict__.
385
Antoine Pitrou653dece2009-05-04 18:32:32 +0000386- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

405
Mark Dickinson95bc9802009-04-24 12:46:53 +0000406- Issue #5816: complex(repr(z)) now recovers z exactly, even when
407 z involves nans, infs or negative zeros.
408
Eric Smithaca19e62009-04-22 13:29:05 +0000409- Implement PEP 378, Format Specifier for Thousands Separator, for
410 floats, ints, and longs.
411
412- Issue #5515: 'n' formatting for ints, longs, and floats handles
413 leading zero formatting poorly.
414
415- Issue #5772: For float.__format__, don't add a trailing ".0" if
416 we're using no type code and we have an exponent.
417

422 some builtin types.
423
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000424- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000425 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000426
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000427- Issue #5759: float() didn't call __float__ on str subclasses.
428
Georg Brandl3c4a5462009-04-12 12:08:12 +0000429- Issue #5704: the "-3" command-line option now implies "-t".

442 the end sys.path, for compatibility with the system install of Python.
443
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000444- Issue #4688: Add a heuristic so that tuples and dicts containing only
445 untrackable objects are not tracked by the garbage collector. This can
446 reduce the size of collections and therefore the garbage collection overhead
447 on long-running programs, depending on their particular use of datatypes.
448
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000449- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
450 improve its performance. Long divisions and remainder operations
451 are now between 50% and 150% faster.
452
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000453- Issue #4258: Make it possible to use base 2**30 instead of base
454 2**15 for the internal representation of integers, for performance
455 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
456 --enable-big-digits option to configure, which overrides the
457 default. Add sys.long_info structseq to provide information about
458 the internal format.
459
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000460- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
461 result traceback.__members__ no longer exists.)
462
Mark Dickinson6b265f12009-03-18 16:07:26 +0000463- Issue #4474: PyUnicode_FromWideChar now converts characters outside
464 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

466
Eric Smith6f42edb2009-03-14 11:57:26 +0000467- Issue #5237: Allow auto-numbered fields in str.format(). For
468 example: '{} {}'.format(1, 2) == '1 2'.
469
Brett Cannon6c4cff02009-03-11 04:51:06 +0000470- Issue #3652: Make the 'line' argument for warnings.showwarning() a
471 requirement. Means the DeprecationWarning from Python 2.6 can go away.
472
Eric Smithe9fb6862009-02-20 14:02:36 +0000473- Issue #5247: Improve error message when unknown format codes are
474 used when using str.format() with str, unicode, long, int, and
475 float arguments.
476
Raymond Hettinger08259e82009-02-18 23:10:19 +0000477- Running Python with the -3 option now also warns about classic division
478 for ints and longs.
479
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000480- Issue #5260: Long integers now consume less memory: average
481 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
482 on a 64-bit system.
483
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000484- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
485 rotating the object pointer by 4 bits to the right.
486
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000487- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
488 it now forces its argument to double before testing for infinity.
489
Benjamin Petersone18ef192009-01-20 14:21:16 +0000490- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
491
Georg Brandl29c6a282009-04-05 20:23:13 +0000492- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000493 were suppressing all exceptions. These include list(), filter(), map(),
494 zip(), and bytearray().
495
Benjamin Peterson596d3062009-01-19 15:42:23 +0000496- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
497 functions.
498

503
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000504- Issue #4935: The overflow checking code in the expandtabs() method common
505 to str, bytes and bytearray could be optimized away by the compiler, letting
506 the interpreter segfault instead of raising an error.

514
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000515- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
516 collecting the oldest generation) so that allocating lots of objects without
517 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000518 Martin von Löwis at

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

539
Benjamin Peterson7af65562008-12-29 17:56:58 +0000540- Issue #4764: With io.open, IOError.filename is set when trying to open a

Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000583 method on file objects with closefd=False. The file descriptor is still
584 kept open but the file object behaves like a closed file. The ``FileIO``
585 object also got a new readonly attribute ``closefd``.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000608- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
609 returned a path longer than MAX_PATH. (But It's doubtful this code path is
610 really executed because I cannot move to such directory on win2k)

Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000612- Issue #4069: When set.remove(element) is used with a set element, the element
613 is temporarily replaced with an equivalent frozenset. But the eventual

615 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000635- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
636 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
637 step. This avoids problems with counting UTF-8 bytes that ignores the effect
638 of using the replace error handler in PyUnicode_DecodeUTF8().
639
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000640- Issue #3739: The unicode-internal encoder now reports the number of characters

642
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000643- Issue #2422: When compiled with the ``--with-valgrind`` option, the
644 pymalloc allocator will be automatically disabled when running under
645 Valgrind. This gives improved memory leak detection when running
646 under Valgrind, while taking advantage of pymalloc at other times.

716 to execute file paths that refer to source or compiled Python files as well
717 as zipfiles, directories and other valid sys.path entries that contain a

1883 leak-chasing test runs give sensible results. The previous method of

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002026- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2027
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002028- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2029 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2030 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2031 ``printf`` function, whereas PyString_FromFormat has an independent
2032 implementation and uses "%zd" on all platforms for size_t values.
2033 This makes a difference on win64, where ``printf`` needs "%Id" to display
2034 64bit values.
2035
Benjamin Peterson97179b02008-09-09 20:55:01 +00002036- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2037 error.
2038
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002039- Issue #3777: long() applied to a float object now always return a long
2040 object; previously an int would be returned for small values. the __long__
2041 method is allowed to return either an int or a long, but the behaviour of
2042 float objects should not change to respect backward compatibility.
2043
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002044- Issue #3751: str.rpartition would perform a left-partition when called with
2045 a unicode argument.
2046
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002047- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002050 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002051 was correctly parsed but parsing of subsequent arguments failed.
2052
Vinay Sajip35e3b032008-09-01 14:33:59 +00002053- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002054 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2055 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2056 when given a tuple of classes as second argument, were looking up
2057 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2058 type object.
2059
Neal Norwitz18aa3882008-08-24 05:04:52 +00002060- Fix crashes on memory allocation failure found with failmalloc.

2129 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2130 for catch_warnings() also led to an improvement in the raising of a
2131 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002201
2202Core and Builtins
2203-----------------
2204
Guido van Rossumf8402962008-08-20 15:01:50 +00002205- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2206 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2207 extensions do not automatically benefit from the class attribute
2208 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2209 to their tp_flags field if they care. This is a backwards
2210 compatibility feature; in 3.0, all types will use the cache by
2211 default.
2212
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002213- Keyword arguments can now follow starred arguments. (``f(a, *args,
2214 keyword=23)`` is now valid syntax.)
2215
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002216- ctypes function pointers that are COM methods have a boolean True
2217 value again.
2218
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002219- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2220 by denying s# to parse objects that have a releasebuffer procedure,
2221 and introducing s*.
2222
Georg Brandl1e13ea92008-08-11 09:07:59 +00002223- Issue #3537: Fix an assertion failure when an empty but presized dict
2224 object was stored in the freelist.
2225
Mark Dickinsonb6467572008-08-04 21:30:09 +00002226- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2227 ValueError consistently across platforms.
2228
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002229- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2230 (64bit Unix, for example), unichr() would truncate its argument and return
2231 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2232
Neal Norwitze7d8be82008-07-31 17:17:14 +00002233- Apply security patches from Apple.
2234
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002235- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2236 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2237
Antoine Pitrou92f82162008-07-25 22:22:08 +00002238- Issue #1819: function calls with several named parameters are now on
2239 average 35% faster (as measured by pybench).
2240
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002241- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2242 the python debugger steps into a class statement: the free variables (local
2243 variables defined in an outer scope) would be deleted from the outer scope.
2244
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002245- Issue #2620: Overflow checking when allocating or reallocating memory
2246 was not always being done properly in some python types and extension
2247 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2248 all been updated to perform better checks and places in the code that
2249 would previously leak memory on the error path when such an allocation
2250 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002255- Issue #3612: Added some missing basic types in ctypes.wintypes.
2256
Benjamin Petersone977ad42008-08-20 01:42:01 +00002257- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2258 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2259
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002260- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2261 version reported by these tools does not necessarily follow the python
2262 version numbering scheme, so the module is less strict when parsing it.
2263
Nick Coghlanf70385a2008-08-18 12:42:46 +00002264- Issue #2235: Added Py3k warnings for types which will become unhashable
2265 under the stricter __hash__ inheritance rules in 3.0. Several types
2266 which did not meet the rules for hash invariants and were already
2267 unhashable in 3.0 have now been explicitly flagged as unhashable in
2268 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2269 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2270
Brett Cannon88f801d2008-08-18 00:46:22 +00002271- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2272 imported into the module but exposed as part of the module's API.
2273

2397-----------------
2398
Georg Brandl3e483f62008-07-16 22:57:41 +00002399- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2400 its methods now allow for items objects that can be converted to
2401 an integer using operator.index().
2402
Mark Dickinson64b7e502008-07-16 09:40:03 +00002403- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2404 produced a ValueError instead of giving the correct float.
2405
Eric Smitha5fa5a22008-07-16 00:11:49 +00002406- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2407 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2408
Mark Dickinson7103aa42008-07-15 19:08:33 +00002409- Issue #3008: the float type has a new instance method 'float.hex'
2410 and a new class method 'float.fromhex' to convert floating-point
2411 numbers to and from hexadecimal strings, respectively.
2412
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002413- Issue #2235: __hash__ is once again inherited by default. To allow
2414 collections.Hashable to remain meaningful in the presence of the
2415 default hash implementation (object.__hash__), it is now possible
2416 to explicit block inheritance of hash by setting __hash__=None at
2417 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2418 level.
2419
Nick Coghlanb028f502008-07-13 14:52:36 +00002420- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2421 the parent module cannot be found while performing an absolute import.
2422 This means that an incorrectly defined __package__ attribute will
2423 now only prevent relative imports in that module rather than causing
2424 all imports from that module to fail.
2425
Nick Coghlan14ff9942008-07-08 14:21:42 +00002426- Issue #2517: Allow unicode messages in Exceptions again by correctly

2436 another thread's dictionary.
2437
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002438- Issue #3004: Minor change to slice.indices(): the start and stop
2439 arguments are now treated identically, making the behaviour easier
2440 to describe and understand. For example, slice(None, -10,
2441 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2442 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2443 10, -1).
2444
Georg Brandl278fc502008-07-19 12:46:12 +00002445- Issue #3219: Calling a function with repeated keyword arguments,
2446 f(a=2, a=23), would not cause a syntax error. This was a regression
2447 from 2.4 caused by the switch to the new compiler.

2486 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002487 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002488 content-length. The problem had been corrected in the 2.4 branch, but never

2896 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002897 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002898
2899 This is controlled by the configure argument ``--with-universal-archs``:
2900
2901 - ``--with-universal-archs=all``: install 4-way universal
2902
2903 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2904
2905 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2906
2907 This option should be used in combination with ``--enable-universalsdk=``.
2908
2909 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002959- Issue #1631171: Re-implement the 'warnings' module in C (the
2960 original Python code has been kept as backup). This will allow for
2961 using the 'warning's machinery in such places as the parser where
2962 use of pure Python code is not possible. Both the ``showarning()``
2963 and ``formatwarning()`` gain an optional 'line' argument which is
2964 not called by default for backwards-compatibility reasons. Setting
2965 ``warnings.showwarning()`` to an implementation that lacks support
2966 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003029- Issue #2550: The approach used by client/server code for obtaining
3030 ports to listen on in network-oriented tests has been refined in an
3031 effort to facilitate running multiple instances of the entire
3032 regression test suite in parallel without issue.
3033 test_support.bind_port() has been fixed such that it will always
3034 return a unique port -- which wasn't always the case with the
3035 previous implementation, especially if socket options had been set
3036 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3037 new implementation of bind_port() will actually raise an exception
3038 if it is passed an AF_INET/SOCK_STREAM socket with either the
3039 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3040 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3041 the socket it's been passed. This currently only applies to
3042 Windows. This option prevents any other sockets from binding to the
3043 host/port we've bound to, thus removing the possibility of the
3044 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3045 when a second SOCK_STREAM socket binds and accepts to a host/port
3046 that's already been bound by another socket. The optional preferred
3047 port parameter to bind_port() has been removed. Under no
3048 circumstances should tests be hard coding ports!
3049
3050 test_support.find_unused_port() has also been introduced, which will
3051 pass a temporary socket object to bind_port() in order to obtain an
3052 unused port. The temporary socket object is then closed and
3053 deleted, and the port is returned. This method should only be used
3054 for obtaining an unused port in order to pass to an external program
3055 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3056 a parameter to a server-oriented class that doesn't give you direct
3057 access to the underlying socket used.
3058
3059 Finally, test_support.HOST has been introduced, which should be used
3060 for the host argument of any relevant socket calls (i.e. bind and
3061 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003062
3063 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003064 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003065 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3066 test_asynchat and test_socket_ssl.
3067
Georg Brandl3ee81df2008-05-17 18:14:43 +00003068 It is now possible for multiple instances of the regression test
3069 suite to run in parallel without issue.

3122
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003123- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003124 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3125 Plane. This affected raw unicode literals and the
3126 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3127 this case, like normal unicode literals and the 'unicode-escape'
3128 codec.

3337
Fred Drakea8ee94b2008-03-01 02:45:07 +00003338- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003339 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003344
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003345- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003346 issue 215555 for a discussion.
3347
Eric Smitha73fbe72008-02-23 03:09:44 +00003348- Added the future_builtins module, which contains hex() and oct().
3349 These are the PEP 3127 version of these functions, designed to be
3350 compatible with the hex() and oct() builtins from Python 3.0. They
3351 differ slightly in their output formats from the existing, unchanged
3352 Python 2.6 builtins. The expected usage of the future_builtins
3353 module is:
3354 from future_builtins import hex, oct
3355
Eric Smith7ef40bf2008-02-20 23:34:22 +00003356- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3357 exponents for exponents with absolute value < 100. Follows C99
3358 standard. This is a change on Windows, which would use 3 digits.
3359 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3360 so that any alterations it does to the resulting string will be
3361 available in stringlib/formatter.h (for float.__format__).
3362
Eric Smith5a3c1352008-02-19 13:21:56 +00003363- Implemented PEP 3101, Advanced String Formatting. This adds a new
3364 builtin format(); a format() method for str and unicode; a
3365 __format__() method to object, str, unicode, int, long, float, and
3366 datetime; the class string.Formatter; and the C API
3367 PyObject_Format().
3368
Georg Brandl3ee81df2008-05-17 18:14:43 +00003369- Fixed several potential crashes, all caused by specially crafted
3370 __del__ methods exploiting objects in temporarily inconsistent
3371 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003372
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003373- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003374 prevent a possible crash: an Abstract Base Class would try to access
3375 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003376

Georg Brandl3ee81df2008-05-17 18:14:43 +00003380- Clear all free lists during a gc.collect() of the highest generation
3381 in order to allow pymalloc to free more arenas. Python may give back
3382 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Issue #2045: Fix an infinite recursion triggered when printing a
3385 subclass of collections.defaultdict, if its default_factory is set

Georg Brandl3ee81df2008-05-17 18:14:43 +00003394- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3395 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003396 to compact the internal free lists of pre-allocted ints and floats.
3397
Georg Brandl3ee81df2008-05-17 18:14:43 +00003398- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3399 calls. Python expected the return type int but the fork familie
3400 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003401
Georg Brandl3ee81df2008-05-17 18:14:43 +00003402- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3403 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Patch #1473257: generator objects gain a gi_code attribute. This is
3415 the same object as the func_code attribute of the function that
3416 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003417
Georg Brandl3ee81df2008-05-17 18:14:43 +00003418- Issue #1920: "while 0" statements were completely removed by the
3419 compiler, even in the presence of an "else" clause, which is
3420 supposed to be run when the condition is false. Now the compiler
3421 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003422
Guido van Rossumeead05f2008-01-24 18:21:02 +00003423- A few crashers fixed: weakref_in_del.py (issue #1377858);
3424 loosing_dict_ref.py (issue #1303614, test67.py);
3425 borrowed_ref_[34].py (not in tracker).
3426
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003427- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003428 suppressed while an extension is loaded by calling SetErrorMode in
3429 dynload_win.c. The error is still reported properly.
3430
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003432 several extension methods and modules do not work without unicode
3433 support.
3434
Georg Brandl26543b12008-01-21 18:36:51 +00003435- Issue #1882: when compiling code from a string, encoding cookies in the
3436 second line of code were not always recognized correctly.
3437
Georg Brandl14404b62008-01-19 19:27:05 +00003438- Issue #1679: "0x" was taken as a valid integer literal.
3439
Georg Brandl6caad7d2008-01-26 14:19:22 +00003440- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003441 added.
3442
Christian Heimesc94e2b52008-01-14 04:13:37 +00003443- sys.float_info / PyFloat_GetInfo: The floating point information
3444 object was converted from a dict to a specialized structseq object.
3445
Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Patch #1816: Added sys.flags structseq. It exposes the status of
3447 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003448
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449- Objects/structseq.c: Implemented new structseq representation. The
3450 patch makes structseqs (e.g. the return value of os.stat) more
3451 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003452
Georg Brandl3ee81df2008-05-17 18:14:43 +00003453- Patch #1700288: added a type attribute cache that caches method
3454 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003455
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003456- Bug #1776: __import__() no longer accepts filenames on any platform.
3457 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003458
Georg Brandlaed6c662008-01-07 17:25:53 +00003459- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3460

3462 envvar and sys.dont_write_bytecode attribute. All these can be set
3463 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Improve some exception messages when Windows fails to load an
3466 extension module. Now we get for example '%1 is not a valid Win32
3467 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003468

Christian Heimes0a8143f2007-12-18 23:22:54 +00003474- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003475 and INF. float("nan"), float("inf") and float("-inf") now work on
3476 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003477
Georg Brandl3ee81df2008-05-17 18:14:43 +00003478- Compiler now generates simpler and faster code for dictionary
3479 literals. The oparg for BUILD_MAP now indicates an estimated
3480 dictionary size. There is a new opcode, STORE_MAP, for adding
3481 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- Patch #1739468: Directories and zipfiles containing a __main__.py
3511 file can now be directly executed by passing their name to the
3512 interpreter. The directory/zipfile is automatically inserted as the
3513 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003514
Georg Brandl3ee81df2008-05-17 18:14:43 +00003515- Issue #1265: Fix a problem with sys.settrace, if the tracing
3516 function uses a generator expression when at the same time the
3517 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003518
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003519- sets and frozensets now have an isdisjoint() method.
3520

3524
Georg Brandl3ee81df2008-05-17 18:14:43 +00003525- The enumerate() builtin function is no longer bounded to sequences
3526 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3527 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003528
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529- Issue #1686386: Tuple's tp_repr did not take into account the
3530 possibility of having a self-referential tuple, which is possible
3531 from C code. Nor did object's tp_str consider that a type's tp_str
3532 could do something that could lead to an inifinite recursion.
3533 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3534 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003535
Georg Brandl3ee81df2008-05-17 18:14:43 +00003536- Issue #1164: It was possible to trigger deadlock when using the
3537 'print' statement to write to a file since the GIL was not released
3538 as needed. Now PyObject_Print() does the right thing along with
3539 various tp_print implementations of the built-in types and those in
3540 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003541
Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Issue #1147: Exceptions were directly allowing string exceptions in

3544 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003545

Brett Cannon1e534b52007-09-07 04:18:30 +00003549- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550 PyObject_Call() never calling back out to Python code to trigger
3551 recursion depth updates/checks. Required the creation of a static
3552 RuntimeError instance in case normalizing an exception put the
3553 recursion check value past its limit. Fixes crashers
3554 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003555

Neal Norwitz0ac60192007-05-27 04:08:54 +00003569- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003570 __*__ attributes. (Some already existed, e.g., __doc__ and
3571 __name__.)

3577 calls.
3578
Collin Winter62903052007-05-18 23:11:24 +00003579- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003580 "except E as target:". This is to provide forwards compatibility
3581 with Python 3.0.

3587
Vinay Sajip8549ce32007-05-06 17:53:37 +00003588- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003589 setting a plain string, ie don't expand to single letter identifiers.
3590
Raymond Hettinger13936692007-04-11 18:40:58 +00003591- Request #1191699: Slices can now be pickled.
3592
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003593- Request #1193128: str.translate() now allows a None argument for

3595 remaining characters.
3596
Georg Brandl5cb76c12007-03-21 09:00:39 +00003597- Patch #1682205: a TypeError while unpacking an iterable is no longer
3598 masked by a generic one with the message "unpack non-sequence".
3599
Neal Norwitzaa754b72007-03-21 06:39:48 +00003600- Remove unused file Python/fmod.c.
3601
Guido van Rossum143b5642007-03-23 04:58:42 +00003602- Bug #1683368: The object.__init__() and object.__new__() methods are
3603 now stricter in rejecting excess arguments. The only time when
3604 either allows excess arguments is when it is not overridden and the
3605 other one is. For backwards compatibility, when both are
3606 overridden, it is a deprecation warning (for now; maybe a Py3k

Georg Brandl3ee81df2008-05-17 18:14:43 +00003610- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3611 object to complex using its __complex__() method before falling back
3612 to the __float__() method. Therefore, the functions in the cmath
3613 module now can operate on objects that define a __complex__()
3614 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003636 its argument, if it exists. If not, it will work like before. This
3637 allows customizing the output of dir() in the presence of a
3638 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003650- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003720- Bug #1545497: when given an explicit base, int() did ignore NULs
3721 embedded in the string to convert.
3722
Georg Brandl846f73a2006-10-08 07:11:54 +00003723- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003771 generator expressions (x for x, in ... ) works again. Fixing this
3772 problem required changing the .pyc magic number. This means that
3773 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004580- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4581 with RFC 3207 and forgets any knowledge obtained from the server not
4582 obtained from the TLS negotiation itself. Patch contributed by Bill
4583 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004584
Georg Brandl3ee81df2008-05-17 18:14:43 +00004585- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004586 that the SMTP.starttls() caller no longer needs to call ehlo()
4587 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004588 does not claim to support starttls. Adds the
4589 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4670 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4671 silently miscode subclasses of those types. Now, it raises a
4672 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004673

Georg Brandl3ee81df2008-05-17 18:14:43 +00004688 time so that opening a database previously created with the DB_DUP
4689 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4690 opens. Specifically: dictionary assignment to a DB object will
4691 replace all values for a given key when the database allows
4692 duplicate values. DB users should use DB.put(k, v) when they want
4693 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004694

4700 characters with ASCII value less than 32. Also, it correctly quotes
4701 dots only if they occur on a single line, as opposed to the previous
4702 behavior of quoting dots if they are the second character of any
4703 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004704
