Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000015- Issue #7419: setlocale() could crash the interpreter on Windows when called
16 with invalid values.
17
Eric Smithc4ab8332009-11-29 17:40:57 +000018- Issue #3382: 'F' formatting for float and complex now convert the
19 result to upper case. This only affects 'inf' and 'nan', since 'f'
20 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000021
Mark Dickinson9dd5e162009-11-23 20:54:09 +000022- Remove switch from "%f" formatting to "%g" formatting for floats
23 larger than 1e50 in absolute value.
24
Mark Dickinson18cfada2009-11-23 18:46:41 +000025- Remove restrictions on precision when formatting floats. E.g.,
26 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
27 requested 120 significant digits instead.
28
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000029- Add Py3k warnings for parameter names in parenthesis.
30
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000031- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000032
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000033- Issue #7085: Fix crash when importing some extensions in a thread
34 on MacOSX 10.6.
35
Mark Dickinsonb678de82009-11-19 18:41:49 +000036- Issue #7117: repr(x) for a float x returns a result based on the
37 shortest decimal string that's guaranteed to round back to x under
38 correct rounding (with round-half-to-even rounding mode).
39 Previously it gave a string based on rounding x to 17 decimal digits.
40 repr(x) for a complex number behaves similarly. On platforms where
41 the correctly-rounded strtod and dtoa code is not supported (see below),
42 repr is unchanged.
43
44- Issue #7117: On almost all platforms: float-to-string and
45 string-to-float conversions within Python are now correctly rounded.
46 Places these conversions occur include: str for floats and complex
47 numbers; the float and complex constructors; old-style and new-style
48 numeric formatting; serialization and deserialization of floats and
49 complex numbers using marshal, pickle and json; parsing of float and
50 imaginary literals in Python code; Decimal-to-float conversion.
51
52 The conversions use a Python-adapted version of David Gay's
53 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
54 functions. This code is supported on Windows, and on Unix-like
55 platforms using gcc, icc or suncc as the C compiler. There may be a
56 small number of platforms on which correct operation of this code
57 cannot be guaranteed, so the code is not used: notably, this applies
58 to platforms where the C double format is not IEEE 754 binary64, and
59 to platforms on x86 hardware where the x87 FPU is set to 64-bit
60 precision and Python's configure script is unable to determine how
61 to change the FPU precision. On these platforms conversions use the
62 platform strtod and dtoa, as before.
63
Mark Dickinsonbd15a062009-11-18 19:33:35 +000064- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000065 now uses the correctly-rounded string <-> float conversions
66 described above (when available), and so produces correctly rounded
67 results that will display nicely under the float repr. There are
68 two related small changes: (1) round now accepts any class with an
69 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000070 floats for the second argument), and (2) an excessively large second
71 integer argument (e.g., round(1.234, 10**100)) no longer raises an
72 exception.
73
Philip Jenveyfab8be22009-11-17 02:42:26 +000074- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
75
Benjamin Petersone36199b2009-11-12 23:39:44 +000076- Fix several issues with compile(). The input can now contain Windows and Mac
77 newlines and is no longer required to end in a newline.
78
Mark Dickinsonc04c7c52009-10-26 22:28:14 +000079- Remove length limitation when constructing a complex number from a
80 unicode string.
81
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +000082- Issue #7244: itertools.izip_longest() no longer ignores exceptions
83 raised during the formation of an output tuple.
84
Mark Dickinson8d87dc02009-10-25 20:39:06 +000085- Issue #1087418: Boost performance of bitwise operations for longs.
86
Antoine Pitrouefb60c02009-10-20 21:29:37 +000087- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
88 fixes the problem of some exceptions being thrown at shutdown when the
89 interpreter is killed. Patch by Adam Olsen.
90
Eric Smithc12781a2009-10-19 14:38:14 +000091- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and
92 note that they are unsafe and deprecated.
93
Vinay Sajip03d5c342009-10-16 14:06:44 +000094- Issue #7120: logging: Removed import of multiprocessing which is causing
95 crash in GAE.
96
Benjamin Peterson196b0922009-10-15 15:44:46 +000097- Issue #7140: The __dict__ of a module should not be cleared unless the module
98 is the only object holding a reference to it.
99
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000100- Issue #1754094: Improve the stack depth calculation in the compiler.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000200- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
201 statement and correctly lookup the __enter__ and __exit__ special methods.
202
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000203- Issue #5829: complex("1e500") no longer raises OverflowError. This
204 makes it consistent with float("1e500") and interpretation of real
205 and imaginary literals.
206
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000207- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

213
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000214- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
215 (1) inf and nan strings with trailing whitespace were incorrectly
216 rejected; (2) parsing of strings representing infinities and nans
217 was locale aware; and (3) the interpretation of fromhex('-nan')
218 didn't match that of float('-nan').
219
Eric Smitha985a3a2009-05-05 18:26:08 +0000220- Issue #5920: For float.__format__, change the behavior with the
221 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
222 to be like 'g' but with at least one decimal point and with a
223 default precision of 12. Previously, the behavior the same but with
224 a default precision of 6. This more closely matches str(), and
225 reduces surprises when adding alignment flags to the empty
226 presentation type. This also affects the new complex.__format__ in
227 the same way.
228
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000229- Issue #5890: in subclasses of 'property' the __doc__ attribute was
230 shadowed by classtype's, even if it was None. property now
231 inserts the __doc__ into the subclass instance __dict__.
232
Antoine Pitrou653dece2009-05-04 18:32:32 +0000233- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

235
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000236- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000237 format(complex(1, 2./3), '.5') now produces a sensible result.
238
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000239- Issue #5864: Fix empty format code formatting for floats so that it
240 never gives more than the requested number of significant digits.
241
Eric Smithcac7af62009-04-27 19:04:37 +0000242- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

246 titlecase, but not their own uppercase.
247
Eric Smith068f0652009-04-25 21:40:15 +0000248- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
249 _PyOS_double_to_string or PyOS_double_to_string.
250
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000251- Issue #5283: Setting __class__ in __del__ caused a segfault.
252
Mark Dickinson95bc9802009-04-24 12:46:53 +0000253- Issue #5816: complex(repr(z)) now recovers z exactly, even when
254 z involves nans, infs or negative zeros.
255
Eric Smithaca19e62009-04-22 13:29:05 +0000256- Implement PEP 378, Format Specifier for Thousands Separator, for
257 floats, ints, and longs.
258
259- Issue #5515: 'n' formatting for ints, longs, and floats handles
260 leading zero formatting poorly.
261
262- Issue #5772: For float.__format__, don't add a trailing ".0" if
263 we're using no type code and we have an exponent.
264
Mark Dickinson6736cf82009-04-20 21:13:33 +0000265- Issue #3166: Make long -> float (and int -> float) conversions
266 correctly rounded.
267
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000268- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
269 some builtin types.
270
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000271- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000272 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000273
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000274- Issue #5759: float() didn't call __float__ on str subclasses.
275
Georg Brandl3c4a5462009-04-12 12:08:12 +0000276- Issue #5704: the "-3" command-line option now implies "-t".
277

287
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000288- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
289 the end sys.path, for compatibility with the system install of Python.
290
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000291- Issue #4688: Add a heuristic so that tuples and dicts containing only
292 untrackable objects are not tracked by the garbage collector. This can
293 reduce the size of collections and therefore the garbage collection overhead
294 on long-running programs, depending on their particular use of datatypes.
295
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000296- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
297 improve its performance. Long divisions and remainder operations
298 are now between 50% and 150% faster.
299
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000300- Issue #4258: Make it possible to use base 2**30 instead of base
301 2**15 for the internal representation of integers, for performance
302 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
303 --enable-big-digits option to configure, which overrides the
304 default. Add sys.long_info structseq to provide information about

Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000307- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
308 result traceback.__members__ no longer exists.)
309
Mark Dickinson6b265f12009-03-18 16:07:26 +0000310- Issue #4474: PyUnicode_FromWideChar now converts characters outside
311 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
312 and sizeof(Py_UNICODE) == 2.
313
Eric Smith6f42edb2009-03-14 11:57:26 +0000314- Issue #5237: Allow auto-numbered fields in str.format(). For
315 example: '{} {}'.format(1, 2) == '1 2'.
316
Brett Cannon6c4cff02009-03-11 04:51:06 +0000317- Issue #3652: Make the 'line' argument for warnings.showwarning() a
318 requirement. Means the DeprecationWarning from Python 2.6 can go away.
319
Eric Smithe9fb6862009-02-20 14:02:36 +0000320- Issue #5247: Improve error message when unknown format codes are
321 used when using str.format() with str, unicode, long, int, and
322 float arguments.
323
Raymond Hettinger08259e82009-02-18 23:10:19 +0000324- Running Python with the -3 option now also warns about classic division
325 for ints and longs.
326
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000327- Issue #5260: Long integers now consume less memory: average
328 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
329 on a 64-bit system.
330
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000331- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
332 rotating the object pointer by 4 bits to the right.
333
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000334- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
335 it now forces its argument to double before testing for infinity.
336
Benjamin Petersone18ef192009-01-20 14:21:16 +0000337- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
338
Georg Brandl29c6a282009-04-05 20:23:13 +0000339- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000340 were suppressing all exceptions. These include list(), filter(), map(),
341 zip(), and bytearray().
342
Benjamin Peterson596d3062009-01-19 15:42:23 +0000343- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
344 functions.
345
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000346- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

350
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000351- Issue #4935: The overflow checking code in the expandtabs() method common
352 to str, bytes and bytearray could be optimized away by the compiler, letting
353 the interpreter segfault instead of raising an error.
354
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000355- Issue #3720: Fix a crash when an iterator modifies its class and removes its

361
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000362- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
363 collecting the oldest generation) so that allocating lots of objects without
364 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000365 Martin von Löwis at

369
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000370- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
371 an existing .py counterpart, override the co_filename attributes of all
372 code objects if the original filename is obsolete (which can happen if the
373 file has been renamed, moved, or if it is accessed through different paths).
374 Patch by Ziga Seilnacht and Jean-Paul Calderone.
375
Martin v. Löwis5344c992009-01-02 20:32:55 +0000376- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000378- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
379 file with `str' filename on Windows.
380
Antoine Pitrouaa687902009-01-01 14:11:22 +0000381- Issue #3680: Reference cycles created through a dict, set or deque iterator
382 did not get collected.
383
Nick Coghlan180e4002008-12-30 01:18:48 +0000384- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
385 where the tp_hash and tp_dict slots are both NULL.
386
Benjamin Peterson7af65562008-12-29 17:56:58 +0000387- Issue #4764: With io.open, IOError.filename is set when trying to open a
388 directory on POSIX systems.
389
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000390- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
391 systems.
392
Georg Brandl6425a2f2008-12-28 11:54:53 +0000393- Issue #4759: None is now allowed as the first argument of
394 bytearray.translate(). It was always allowed for bytes.translate().
395
Skip Montanarof205c132008-12-23 03:30:15 +0000396- Added test case to ensure attempts to read from a file opened for writing
397 fail.
398
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000399- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

401 unreachable. Original patch by Neil Schemenauer.
402

407
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000408- Issue #4597: Fixed exception handling when the __exit__ function of a
409 context manager returns a value that cannot be converted to a bool.
410
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000411- Issue #4597: Fixed several opcodes that weren't always propagating
412 exceptions.
413
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000414- Issue #4445: Replace "sizeof(PyStringObject)" with
415 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
416 str instances. On a typical machine this saves 3 bytes of memory
417 (on average) per string allocation.
418
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000419- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
420 interpreter to abort ("Fatal Python error: Could not reset the stack!")
421 instead of throwing a MemoryError.
422
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000423- Issue #3689: The list reversed iterator now supports __length_hint__
424 instead of __len__. Behavior now matches other reversed iterators.
425
Benjamin Petersonc078f922008-11-21 22:27:24 +0000426- Issue #4367: Python would segfault during compiling when the unicodedata
427 module couldn't be imported and \N escapes were present.
428
Vinay Sajip213faca2008-12-03 23:22:58 +0000429- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000430 method on file objects with closefd=False. The file descriptor is still
431 kept open but the file object behaves like a closed file. The ``FileIO``
432 object also got a new readonly attribute ``closefd``.
433
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000434- Issue #4348: Some bytearray methods returned that didn't cause any change to
435 the bytearray, returned the same bytearray instead of a copy.
436
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000437- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
438
Benjamin Peterson273c2332008-11-17 22:39:09 +0000439- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
440
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000441- Issue #4048: The parser module now correctly validates relative imports.
442
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000443- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
444 exec statement.
445
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000446- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
447 method does not return iterators for the 4th and 5th items.
448
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000449- Issue #4209: Enabling unicode_literals and the print_function in the same
450 __future__ import didn't work.
451
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000452- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000453 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000454
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000455- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
456 returned a path longer than MAX_PATH. (But It's doubtful this code path is
457 really executed because I cannot move to such directory on win2k)
458
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000459- Issue #4069: When set.remove(element) is used with a set element, the element
460 is temporarily replaced with an equivalent frozenset. But the eventual
461 KeyError would always report the empty frozenset([]) as the missing key. Now
462 it correctly refers to the initial element.
463
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000464- Issue #4509: Various issues surrounding resize of bytearray objects to
465 which there are buffer exports.
466
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000467- Issue #4748: Lambda generators no longer return a value.

475
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000476- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
477 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000479- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
480 returned them on 64bit platforms.
481
Walter Dörwalded960ac2009-05-03 22:36:33 +0000482- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
483 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
484 step. This avoids problems with counting UTF-8 bytes that ignores the effect
485 of using the replace error handler in PyUnicode_DecodeUTF8().
486
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000487- Issue #3739: The unicode-internal encoder now reports the number of characters
488 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrou59c44f32009-10-30 17:07:08 +00001701- Issue #7222: Make thread "reaping" more reliable so that reference
1702 leak-chasing test runs give sensible results. The previous method of
1703 reaping threads could return successfully while some Thread objects were
1704 still referenced. This also introduces a new private function:

1712
R. David Murray14dcd432009-10-14 13:58:07 +00001713- Issue #7058: Added save/restore for things like sys.argv and cwd to

1723 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1724 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1725 skip the tests if DISPLAY is defined but can't be used.
1726
Antoine Pitrou4698d992009-05-31 14:20:14 +00001727- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running

1731 it easy to import both normal and optimised versions of modules.
1732 test_heapq and test_warnings have been adjusted to use it, tests for
1733 other modules with both C and Python implementations in the stdlib
1734 can be adjusted to use it over time.

Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001743 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001744 from test support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001845- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1846
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001847- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1848 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1849 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1850 ``printf`` function, whereas PyString_FromFormat has an independent
1851 implementation and uses "%zd" on all platforms for size_t values.
1852 This makes a difference on win64, where ``printf`` needs "%Id" to display
1853 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001855- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1859 object; previously an int would be returned for small values. the __long__
1860 method is allowed to return either an int or a long, but the behaviour of
1861 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001863- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001869 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001870 was correctly parsed but parsing of subsequent arguments failed.
1871
Vinay Sajip35e3b032008-09-01 14:33:59 +00001872- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001873 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1874 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1875 when given a tuple of classes as second argument, were looking up
1876 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1877 type object.
1878
Neal Norwitz18aa3882008-08-24 05:04:52 +00001879- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002016What's New in Python 2.6 beta 3?
2017================================
2018
Barry Warsaw07a4a382008-08-21 01:15:08 +00002019*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002020
2021Core and Builtins
2022-----------------
2023
Guido van Rossumf8402962008-08-20 15:01:50 +00002024- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2025 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2026 extensions do not automatically benefit from the class attribute
2027 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2028 to their tp_flags field if they care. This is a backwards
2029 compatibility feature; in 3.0, all types will use the cache by
2030 default.
2031
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002032- Keyword arguments can now follow starred arguments. (``f(a, *args,
2033 keyword=23)`` is now valid syntax.)
2034
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002035- ctypes function pointers that are COM methods have a boolean True
2036 value again.
2037
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002038- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2039 by denying s# to parse objects that have a releasebuffer procedure,
2040 and introducing s*.
2041
Georg Brandl1e13ea92008-08-11 09:07:59 +00002042- Issue #3537: Fix an assertion failure when an empty but presized dict
2043 object was stored in the freelist.
2044
Mark Dickinsonb6467572008-08-04 21:30:09 +00002045- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2046 ValueError consistently across platforms.
2047
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002048- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2049 (64bit Unix, for example), unichr() would truncate its argument and return
2050 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2051
Neal Norwitze7d8be82008-07-31 17:17:14 +00002052- Apply security patches from Apple.
2053
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002054- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2055 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2056
Antoine Pitrou92f82162008-07-25 22:22:08 +00002057- Issue #1819: function calls with several named parameters are now on
2058 average 35% faster (as measured by pybench).
2059
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002060- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2061 the python debugger steps into a class statement: the free variables (local
2062 variables defined in an outer scope) would be deleted from the outer scope.
2063
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002064- Issue #2620: Overflow checking when allocating or reallocating memory
2065 was not always being done properly in some python types and extension
2066 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2067 all been updated to perform better checks and places in the code that
2068 would previously leak memory on the error path when such an allocation
2069 failed have been fixed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002071Library
2072-------
2073
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002074- Issue #3612: Added some missing basic types in ctypes.wintypes.
2075
Benjamin Petersone977ad42008-08-20 01:42:01 +00002076- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2077 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2078
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002079- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2080 version reported by these tools does not necessarily follow the python
2081 version numbering scheme, so the module is less strict when parsing it.
2082
Nick Coghlanf70385a2008-08-18 12:42:46 +00002083- Issue #2235: Added Py3k warnings for types which will become unhashable
2084 under the stricter __hash__ inheritance rules in 3.0. Several types
2085 which did not meet the rules for hash invariants and were already
2086 unhashable in 3.0 have now been explicitly flagged as unhashable in
2087 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2088 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2089
Brett Cannon88f801d2008-08-18 00:46:22 +00002090- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2091 imported into the module but exposed as part of the module's API.
2092
Brett Cannon7b96f072008-08-18 00:41:11 +00002093- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2094
Brett Cannon46225e72008-08-18 00:36:52 +00002095- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2096
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002097- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2098
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002099- Issue #3575: Incremental decoder's decode function now takes bytearray
2100 by using 's*' instead of 't#'.
2101
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002102- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002103 fails unicode conversion on 2nd parameter. (windows only)
2104
Facundo Batista94f243a2008-08-17 03:38:39 +00002105- Issue 2464. urllib2 now supports a malformation in the URL received
2106 in a redirect.
2107
Brett Cannonabe423e2008-08-16 21:47:07 +00002108- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002109 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002110
Facundo Batistaeb90b782008-08-16 14:44:07 +00002111- Issue #2776: fixed small issue when handling an URL with double slash
2112 after a 302 response in the case of not going through a proxy.
2113
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002114- Issue #2676: in the email package, content-type parsing was hanging on
2115 pathological input because of quadratic or exponential behaviour of a
2116 regular expression.
2117
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002118- Issue #3476: binary buffered reading through the new "io" library is now
2119 thread-safe.
2120
Brett Cannonbf3157b2008-08-14 05:00:03 +00002121- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2122 since mimetools itself is deprecated. Because modules are cached, all
2123 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2124
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002125- Issue #3134: shutil referenced undefined WindowsError symbol.
2126
Robert Schuppenies14646332008-08-10 11:01:53 +00002127- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2128 menu entries were not deleted.
2129
Brett Cannon83e81842008-08-09 23:30:55 +00002130- Copied the implementation of reduce() to _functools.reduce() to have a
2131 version that did not raise a DeprecationWarning under -3.
2132
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002133- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2134 a MemoryError rather than silently stop the iteration.
2135
Guido van Rossum59ce9012008-08-09 14:55:34 +00002136- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2137 to _sre.compile() will now be rejected. This should not affect anybody
2138 since the re.compile() function never generates invalid re-bytecode.
2139
Skip Montanaroa032bf42008-08-08 22:52:51 +00002140- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2141 upon first access it can be automatically initialized from the csv file if
2142 it wasn't initialized during instantiation.
2143
Brett Cannon3aa2a492008-08-06 22:28:09 +00002144- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2145 the reload() built-in has been removed.
2146
Brett Cannon7e30b672008-08-04 21:52:25 +00002147- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002148 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2152 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2153 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002154
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002155- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2156 raised an AttributeError.
2157
Benjamin Peterson01a24322008-07-28 23:35:27 +00002158- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002159 asking for a specific length. This problem only affected files opened
2160 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002161
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002162- Issue #3449: Update decimal module to use most recent specification
2163 (v. 1.68) and tests (v. 2.58) from IBM.
2164
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002165- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2173
2174- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2175 invalid arguments.
2176
2177- Issue #3302: Fix several crashes when calling locale's gettext functions
2178 with None arguments.
2179
2180- Issue #3389: Allow resolving dotted names for handlers in logging
2181 configuration files.
2182
2183- Deprecate the sunaudio module for removal in Python 3.0.
2184
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002185- Issue #3394: zipfile.writestr sets external attributes when passed a
2186 file name rather than a ZipInfo instance, so files are extracted with
2187 mode 0600 rather than 000 under Unix.
2188
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002189- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2190 argument in python 2.5, this broke code that subclassed Popen to include its
2191 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002201- Issue #2235: the C API function PyObject_HashNotImplemented and its
2202 interaction with the tp_hash slot (added in 2.6b2) are now documented
2203
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002204- Issue #643841: The language reference now provides more detailed
2205 coverage of the lookup process for special methods. The disclaimers
2206 regarding lack of coverage of new-style classes have also been
2207 removed, since the coverage is now fairly reasonable.

2216-----------------
2217
Georg Brandl3e483f62008-07-16 22:57:41 +00002218- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2219 its methods now allow for items objects that can be converted to
2220 an integer using operator.index().
2221
Mark Dickinson64b7e502008-07-16 09:40:03 +00002222- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2223 produced a ValueError instead of giving the correct float.
2224
Eric Smitha5fa5a22008-07-16 00:11:49 +00002225- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2226 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2227
Mark Dickinson7103aa42008-07-15 19:08:33 +00002228- Issue #3008: the float type has a new instance method 'float.hex'
2229 and a new class method 'float.fromhex' to convert floating-point
2230 numbers to and from hexadecimal strings, respectively.
2231
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002232- Issue #2235: __hash__ is once again inherited by default. To allow
2233 collections.Hashable to remain meaningful in the presence of the
2234 default hash implementation (object.__hash__), it is now possible
2235 to explicit block inheritance of hash by setting __hash__=None at
2236 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2237 level.
2238
Nick Coghlanb028f502008-07-13 14:52:36 +00002239- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2240 the parent module cannot be found while performing an absolute import.
2241 This means that an incorrectly defined __package__ attribute will
2242 now only prevent relative imports in that module rather than causing
2243 all imports from that module to fail.
2244
Nick Coghlan14ff9942008-07-08 14:21:42 +00002245- Issue #2517: Allow unicode messages in Exceptions again by correctly
2246 bypassing the instance dictionary when looking up __unicode__ on
2247 new-style classes.
2248
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002249- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2250 set to a custom object whose write() method happens to install
2251 another file in sys.stdout.

2255 another thread's dictionary.
2256
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002257- Issue #3004: Minor change to slice.indices(): the start and stop
2258 arguments are now treated identically, making the behaviour easier
2259 to describe and understand. For example, slice(None, -10,
2260 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2261 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2262 10, -1).
2263
Georg Brandl278fc502008-07-19 12:46:12 +00002264- Issue #3219: Calling a function with repeated keyword arguments,
2265 f(a=2, a=23), would not cause a syntax error. This was a regression
2266 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002716 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002717
2718 This is controlled by the configure argument ``--with-universal-archs``:
2719
2720 - ``--with-universal-archs=all``: install 4-way universal
2721
2722 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2723
2724 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2725
2726 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002778- Issue #1631171: Re-implement the 'warnings' module in C (the
2779 original Python code has been kept as backup). This will allow for
2780 using the 'warning's machinery in such places as the parser where
2781 use of pure Python code is not possible. Both the ``showarning()``
2782 and ``formatwarning()`` gain an optional 'line' argument which is
2783 not called by default for backwards-compatibility reasons. Setting
2784 ``warnings.showwarning()`` to an implementation that lacks support
2785 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002840- Issue #2385: distutils.core.run_script() makes __file__ available,
2841 so the controlled environment will more closely mirror the typical
2842 script environment. This supports setup.py scripts that refer to
2843 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002848- Issue #2550: The approach used by client/server code for obtaining
2849 ports to listen on in network-oriented tests has been refined in an
2850 effort to facilitate running multiple instances of the entire
2851 regression test suite in parallel without issue.
2852 test_support.bind_port() has been fixed such that it will always
2853 return a unique port -- which wasn't always the case with the
2854 previous implementation, especially if socket options had been set
2855 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2856 new implementation of bind_port() will actually raise an exception
2857 if it is passed an AF_INET/SOCK_STREAM socket with either the
2858 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2859 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2860 the socket it's been passed. This currently only applies to
2861 Windows. This option prevents any other sockets from binding to the
2862 host/port we've bound to, thus removing the possibility of the
2863 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2864 when a second SOCK_STREAM socket binds and accepts to a host/port
2865 that's already been bound by another socket. The optional preferred
2866 port parameter to bind_port() has been removed. Under no
2867 circumstances should tests be hard coding ports!
2868
2869 test_support.find_unused_port() has also been introduced, which will
2870 pass a temporary socket object to bind_port() in order to obtain an
2871 unused port. The temporary socket object is then closed and
2872 deleted, and the port is returned. This method should only be used
2873 for obtaining an unused port in order to pass to an external program
2874 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2875 a parameter to a server-oriented class that doesn't give you direct
2876 access to the underlying socket used.
2877
2878 Finally, test_support.HOST has been introduced, which should be used
2879 for the host argument of any relevant socket calls (i.e. bind and
2880 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002881
2882 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002884 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2885 test_asynchat and test_socket_ssl.
2886
Georg Brandl3ee81df2008-05-17 18:14:43 +00002887 It is now possible for multiple instances of the regression test
2888 suite to run in parallel without issue.

3154Core and builtins
3155-----------------
3156
Fred Drakea8ee94b2008-03-01 02:45:07 +00003157- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003158 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003159
Georg Brandlad61bc82008-02-23 15:11:18 +00003160- Issue #2067: file.__exit__() now calls subclasses' close() method.
3161
3162- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003163
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003164- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003165 issue 215555 for a discussion.
3166
Eric Smitha73fbe72008-02-23 03:09:44 +00003167- Added the future_builtins module, which contains hex() and oct().
3168 These are the PEP 3127 version of these functions, designed to be
3169 compatible with the hex() and oct() builtins from Python 3.0. They
3170 differ slightly in their output formats from the existing, unchanged
3171 Python 2.6 builtins. The expected usage of the future_builtins
3172 module is:
3173 from future_builtins import hex, oct
3174
Eric Smith7ef40bf2008-02-20 23:34:22 +00003175- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3176 exponents for exponents with absolute value < 100. Follows C99
3177 standard. This is a change on Windows, which would use 3 digits.
3178 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3179 so that any alterations it does to the resulting string will be
3180 available in stringlib/formatter.h (for float.__format__).
3181
Eric Smith5a3c1352008-02-19 13:21:56 +00003182- Implemented PEP 3101, Advanced String Formatting. This adds a new
3183 builtin format(); a format() method for str and unicode; a
3184 __format__() method to object, str, unicode, int, long, float, and
3185 datetime; the class string.Formatter; and the C API
3186 PyObject_Format().
3187
Georg Brandl3ee81df2008-05-17 18:14:43 +00003188- Fixed several potential crashes, all caused by specially crafted
3189 __del__ methods exploiting objects in temporarily inconsistent
3190 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003191
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003192- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003193 prevent a possible crash: an Abstract Base Class would try to access
3194 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003195
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196- Fixed repr() and str() of complex numbers with infinity or nan as
3197 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003198
Georg Brandl3ee81df2008-05-17 18:14:43 +00003199- Clear all free lists during a gc.collect() of the highest generation
3200 in order to allow pymalloc to free more arenas. Python may give back
3201 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Issue #2045: Fix an infinite recursion triggered when printing a
3204 subclass of collections.defaultdict, if its default_factory is set
3205 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003206
Christian Heimesf75dbef2008-02-08 00:11:31 +00003207- Fixed a minor memory leak in dictobject.c. The content of the free
3208 list was not freed on interpreter shutdown.
3209
Georg Brandl3ee81df2008-05-17 18:14:43 +00003210- Limit free list of method and builtin function objects to 256
3211 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003212
Georg Brandl3ee81df2008-05-17 18:14:43 +00003213- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3214 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003215 to compact the internal free lists of pre-allocted ints and floats.
3216
Georg Brandl3ee81df2008-05-17 18:14:43 +00003217- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3218 calls. Python expected the return type int but the fork familie
3219 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003220
Georg Brandl3ee81df2008-05-17 18:14:43 +00003221- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3222 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003223
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3225 with the collections.Sequence API.

3231 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003232
Georg Brandl3ee81df2008-05-17 18:14:43 +00003233- Patch #1473257: generator objects gain a gi_code attribute. This is
3234 the same object as the func_code attribute of the function that
3235 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003236
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Issue #1920: "while 0" statements were completely removed by the
3238 compiler, even in the presence of an "else" clause, which is
3239 supposed to be run when the condition is false. Now the compiler
3240 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003241
Guido van Rossumeead05f2008-01-24 18:21:02 +00003242- A few crashers fixed: weakref_in_del.py (issue #1377858);
3243 loosing_dict_ref.py (issue #1303614, test67.py);
3244 borrowed_ref_[34].py (not in tracker).
3245
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003246- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003247 suppressed while an extension is loaded by calling SetErrorMode in
3248 dynload_win.c. The error is still reported properly.
3249
Georg Brandl3ee81df2008-05-17 18:14:43 +00003250- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003251 several extension methods and modules do not work without unicode
3252 support.
3253
Georg Brandl26543b12008-01-21 18:36:51 +00003254- Issue #1882: when compiling code from a string, encoding cookies in the
3255 second line of code were not always recognized correctly.
3256
Georg Brandl14404b62008-01-19 19:27:05 +00003257- Issue #1679: "0x" was taken as a valid integer literal.
3258
Georg Brandl6caad7d2008-01-26 14:19:22 +00003259- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003260 added.
3261
Christian Heimesc94e2b52008-01-14 04:13:37 +00003262- sys.float_info / PyFloat_GetInfo: The floating point information
3263 object was converted from a dict to a specialized structseq object.
3264
Georg Brandl3ee81df2008-05-17 18:14:43 +00003265- Patch #1816: Added sys.flags structseq. It exposes the status of
3266 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003267
Georg Brandl3ee81df2008-05-17 18:14:43 +00003268- Objects/structseq.c: Implemented new structseq representation. The
3269 patch makes structseqs (e.g. the return value of os.stat) more
3270 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003271
Georg Brandl3ee81df2008-05-17 18:14:43 +00003272- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003294 and INF. float("nan"), float("inf") and float("-inf") now work on
3295 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003296
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297- Compiler now generates simpler and faster code for dictionary
3298 literals. The oparg for BUILD_MAP now indicates an estimated
3299 dictionary size. There is a new opcode, STORE_MAP, for adding
3300 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003344- The enumerate() builtin function is no longer bounded to sequences
3345 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3346 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003347
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Issue #1686386: Tuple's tp_repr did not take into account the
3349 possibility of having a self-referential tuple, which is possible
3350 from C code. Nor did object's tp_str consider that a type's tp_str
3351 could do something that could lead to an inifinite recursion.
3352 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3353 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003354
Georg Brandl3ee81df2008-05-17 18:14:43 +00003355- Issue #1164: It was possible to trigger deadlock when using the
3356 'print' statement to write to a file since the GIL was not released
3357 as needed. Now PyObject_Print() does the right thing along with
3358 various tp_print implementations of the built-in types and those in
3359 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003360
Georg Brandl3ee81df2008-05-17 18:14:43 +00003361- Issue #1147: Exceptions were directly allowing string exceptions in
3362 their throw() method even though string exceptions no longer
3363 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003364
Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Issue #1096: Prevent a segfault from getting the repr of a very
3366 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003367
Brett Cannon1e534b52007-09-07 04:18:30 +00003368- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003369 PyObject_Call() never calling back out to Python code to trigger
3370 recursion depth updates/checks. Required the creation of a static
3371 RuntimeError instance in case normalizing an exception put the
3372 recursion check value past its limit. Fixes crashers
3373 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003374

Neal Norwitz0ac60192007-05-27 04:08:54 +00003388- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003389 __*__ attributes. (Some already existed, e.g., __doc__ and
3390 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003391
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003392- Add -3 option to the interpreter to warn about features that are
3393 deprecated and will be changed/removed in Python 3.0.
3394
Georg Brandl2134e752007-05-21 20:34:16 +00003395- Patch #1686487: you can now pass any mapping after '**' in function
3396 calls.
3397
Collin Winter62903052007-05-18 23:11:24 +00003398- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003399 "except E as target:". This is to provide forwards compatibility
3400 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003401
Brett Cannon229cee22007-05-05 01:34:02 +00003402- Deprecate BaseException.message as per PEP 352.
3403
Georg Brandl3ee81df2008-05-17 18:14:43 +00003404- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003405 inherited from a builtin base.
3406
Vinay Sajip8549ce32007-05-06 17:53:37 +00003407- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003408 setting a plain string, ie don't expand to single letter identifiers.
3409
Raymond Hettinger13936692007-04-11 18:40:58 +00003410- Request #1191699: Slices can now be pickled.
3411
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003412- Request #1193128: str.translate() now allows a None argument for
3413 translations that only remove characters without re-mapping the
3414 remaining characters.
3415
Georg Brandl5cb76c12007-03-21 09:00:39 +00003416- Patch #1682205: a TypeError while unpacking an iterable is no longer
3417 masked by a generic one with the message "unpack non-sequence".
3418
Neal Norwitzaa754b72007-03-21 06:39:48 +00003419- Remove unused file Python/fmod.c.
3420
Guido van Rossum143b5642007-03-23 04:58:42 +00003421- Bug #1683368: The object.__init__() and object.__new__() methods are
3422 now stricter in rejecting excess arguments. The only time when
3423 either allows excess arguments is when it is not overridden and the
3424 other one is. For backwards compatibility, when both are
3425 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003426 warning later). Also, type.__init__() insists on the same signature
3427 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3430 object to complex using its __complex__() method before falling back
3431 to the __float__() method. Therefore, the functions in the cmath
3432 module now can operate on objects that define a __complex__()
3433 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Patch #1623563: allow __class__ assignment for classes with
3436 __slots__. The old and the new class are still required to have the
3437 same slot names.

3443 ``object.__reduce_ex__()`` is called with an object that is faking
3444 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003445
Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Patch #1680015: Don't modify __slots__ tuple if it contains an

3450
Georg Brandl7b9c5552007-03-12 14:30:05 +00003451- Bug #1678647: write a newline after printing an exception in any
3452 case, even when converting the value to a string failed.
3453
Georg Brandl871f1bc2007-03-12 13:17:36 +00003454- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455 its argument, if it exists. If not, it will work like before. This
3456 allows customizing the output of dir() in the presence of a
3457 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003458
Collin Winter276887b2007-03-12 16:11:39 +00003459- Patch #922167: Python no longer segfaults when faced with infinitely

3466 parthensized forms. This means complex(repr(x)) now works instead of
3467 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003468
Georg Brandlaa2321b2007-03-07 00:40:28 +00003469- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003470 makes the filenames the warning module prints much more sensible
3471 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003472

Georg Brandl0fca97a2007-03-05 22:28:08 +00003484- Patch #1674228: when assigning a slice (old-style), check for the
3485 sq_ass_slice instead of the sq_slice slot.
3486
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487- When printing an unraisable error, don't print exceptions. before
3488 the name. This duplicates the behavior whening normally printing
3489 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003590 generator expressions (x for x, in ... ) works again. Fixing this
3591 problem required changing the .pyc magic number. This means that
3592 .pyc files generated before 2.5c2 will be regenerated.

4118 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004399- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4400 with RFC 3207 and forgets any knowledge obtained from the server not
4401 obtained from the TLS negotiation itself. Patch contributed by Bill
4402 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004403
Georg Brandl3ee81df2008-05-17 18:14:43 +00004404- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004405 that the SMTP.starttls() caller no longer needs to call ehlo()
4406 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004407 does not claim to support starttls. Adds the
4408 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4489 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4490 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004507 time so that opening a database previously created with the DB_DUP
4508 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4509 opens. Specifically: dictionary assignment to a DB object will
4510 replace all values for a given key when the database allows
4511 duplicate values. DB users should use DB.put(k, v) when they want
4512 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004513

4519 characters with ASCII value less than 32. Also, it correctly quotes
4520 dots only if they occur on a single line, as opposed to the previous
4521 behavior of quoting dots if they are the second character of any
4522 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004523

4845-----
4846
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847- Unified naming convention for free lists and their limits. All free
4848 lists in Object/ are named ``free_list``, the counter ``numfree``
4849 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4850 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004851
Georg Brandl3ee81df2008-05-17 18:14:43 +00004852- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4853 to ``PyTuple_SetItem``, it can be used to populate a brand new
4854 frozenset; but it does not steal a reference to the added item.

4863
4864- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4865 ``PyFloat_GetInfo()`` to the float API.
4866
Georg Brandl3ee81df2008-05-17 18:14:43 +00004867- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4868 of w# format code incorrectly truncated the length to an int, even
4869 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4870 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004871
Georg Brandl3ee81df2008-05-17 18:14:43 +00004872- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4890- Fix some leftovers from the conversion from int to Py_ssize_t
4891 (relevant to strings and sequences of more than 2**31 items).
4892
4893- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4894 outside of pystate.c and should not be necessary.
4895
Georg Brandl3ee81df2008-05-17 18:14:43 +00004896- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4897 absolute imports. In earlier versions they might have used relative
4898 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004899
Georg Brandl3ee81df2008-05-17 18:14:43 +00004900- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4901 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004902
Georg Brandl3ee81df2008-05-17 18:14:43 +00004903- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4911 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4912 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4913 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004914

Georg Brandl3ee81df2008-05-17 18:14:43 +00004928- Removed the macfs module. It had been deprecated since Python 2.5.
4929 This lead to the deprecation of macostools.touched() as it relied
