131
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000132- Issue #7419: setlocale() could crash the interpreter on Windows when called
133 with invalid values.
134
Eric Smithc4ab8332009-11-29 17:40:57 +0000135- Issue #3382: 'F' formatting for float and complex now convert the
136 result to upper case. This only affects 'inf' and 'nan', since 'f'
137 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000138
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000139- Remove switch from "%f" formatting to "%g" formatting for floats
140 larger than 1e50 in absolute value.
141
Mark Dickinson18cfada2009-11-23 18:46:41 +0000142- Remove restrictions on precision when formatting floats. E.g.,
143 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
144 requested 120 significant digits instead.
145
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000146- Add Py3k warnings for parameter names in parenthesis.
147
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000148- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000149
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000150- Issue #7085: Fix crash when importing some extensions in a thread
151 on MacOSX 10.6.
152
Mark Dickinsonb678de82009-11-19 18:41:49 +0000153- Issue #7117: repr(x) for a float x returns a result based on the
154 shortest decimal string that's guaranteed to round back to x under
155 correct rounding (with round-half-to-even rounding mode).
156 Previously it gave a string based on rounding x to 17 decimal digits.
157 repr(x) for a complex number behaves similarly. On platforms where
158 the correctly-rounded strtod and dtoa code is not supported (see below),
159 repr is unchanged.
160
161- Issue #7117: On almost all platforms: float-to-string and
162 string-to-float conversions within Python are now correctly rounded.
163 Places these conversions occur include: str for floats and complex
164 numbers; the float and complex constructors; old-style and new-style
165 numeric formatting; serialization and deserialization of floats and
166 complex numbers using marshal, pickle and json; parsing of float and
167 imaginary literals in Python code; Decimal-to-float conversion.
168
169 The conversions use a Python-adapted version of David Gay's
170 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
171 functions. This code is supported on Windows, and on Unix-like
172 platforms using gcc, icc or suncc as the C compiler. There may be a
173 small number of platforms on which correct operation of this code
174 cannot be guaranteed, so the code is not used: notably, this applies
175 to platforms where the C double format is not IEEE 754 binary64, and
176 to platforms on x86 hardware where the x87 FPU is set to 64-bit
177 precision and Python's configure script is unable to determine how
178 to change the FPU precision. On these platforms conversions use the
179 platform strtod and dtoa, as before.
180
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000181- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000182 now uses the correctly-rounded string <-> float conversions
183 described above (when available), and so produces correctly rounded
184 results that will display nicely under the float repr. There are
185 two related small changes: (1) round now accepts any class with an
186 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000187 floats for the second argument), and (2) an excessively large second
188 integer argument (e.g., round(1.234, 10**100)) no longer raises an
189 exception.
190
Philip Jenveyfab8be22009-11-17 02:42:26 +0000191- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
192
Benjamin Petersone36199b2009-11-12 23:39:44 +0000193- Fix several issues with compile(). The input can now contain Windows and Mac
194 newlines and is no longer required to end in a newline.
195

197 unicode string.
198
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000199- Issue #7244: itertools.izip_longest() no longer ignores exceptions

207

213
Benjamin Peterson196b0922009-10-15 15:44:46 +0000214- Issue #7140: The __dict__ of a module should not be cleared unless the module
215 is the only object holding a reference to it.
216
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000217- Issue #1754094: Improve the stack depth calculation in the compiler.
218 There should be no other effect than a small decrease in memory use.
219 Patch by Christopher Tur Lesniewski-Laas.
220
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000221- Issue #7084: Fix a (very unlikely) crash when printing a list from one

313
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000314- Added support for multiple context managers in the same with-statement.
315 Deprecated contextlib.nested() which is no longer needed.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000317- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
318 statement and correctly lookup the __enter__ and __exit__ special methods.
319
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000320- Issue #5829: complex("1e500") no longer raises OverflowError. This
321 makes it consistent with float("1e500") and interpretation of real
322 and imaginary literals.
323
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000324- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
325
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000326- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
327 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000328
R. David Murray525cffc2009-05-13 13:07:14 +0000329- Issue #5994: the marshal module now has docstrings.
330
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000331- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
332 (1) inf and nan strings with trailing whitespace were incorrectly
333 rejected; (2) parsing of strings representing infinities and nans
334 was locale aware; and (3) the interpretation of fromhex('-nan')
335 didn't match that of float('-nan').
336
Eric Smitha985a3a2009-05-05 18:26:08 +0000337- Issue #5920: For float.__format__, change the behavior with the
338 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
339 to be like 'g' but with at least one decimal point and with a
340 default precision of 12. Previously, the behavior the same but with
341 a default precision of 6. This more closely matches str(), and
342 reduces surprises when adding alignment flags to the empty
343 presentation type. This also affects the new complex.__format__ in
344 the same way.
345
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000346- Issue #5890: in subclasses of 'property' the __doc__ attribute was
347 shadowed by classtype's, even if it was None. property now
348 inserts the __doc__ into the subclass instance __dict__.
349
Antoine Pitrou653dece2009-05-04 18:32:32 +0000350- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
351 sequences. Patch by Nick Barnes and Victor Stinner.
352
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000353- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000354 format(complex(1, 2./3), '.5') now produces a sensible result.
355
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000356- Issue #5864: Fix empty format code formatting for floats so that it
357 never gives more than the requested number of significant digits.
358
Eric Smithcac7af62009-04-27 19:04:37 +0000359- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

363 titlecase, but not their own uppercase.
364
Eric Smith068f0652009-04-25 21:40:15 +0000365- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
366 _PyOS_double_to_string or PyOS_double_to_string.
367
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000368- Issue #5283: Setting __class__ in __del__ caused a segfault.
369
Mark Dickinson95bc9802009-04-24 12:46:53 +0000370- Issue #5816: complex(repr(z)) now recovers z exactly, even when
371 z involves nans, infs or negative zeros.
372
Eric Smithaca19e62009-04-22 13:29:05 +0000373- Implement PEP 378, Format Specifier for Thousands Separator, for
374 floats, ints, and longs.
375
376- Issue #5515: 'n' formatting for ints, longs, and floats handles
377 leading zero formatting poorly.
378
379- Issue #5772: For float.__format__, don't add a trailing ".0" if
380 we're using no type code and we have an exponent.
381
Mark Dickinson6736cf82009-04-20 21:13:33 +0000382- Issue #3166: Make long -> float (and int -> float) conversions
383 correctly rounded.
384
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000385- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
386 some builtin types.
387
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000388- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000389 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000390
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000391- Issue #5759: float() didn't call __float__ on str subclasses.
392
Georg Brandl3c4a5462009-04-12 12:08:12 +0000393- Issue #5704: the "-3" command-line option now implies "-t".
394
R. David Murray0374a822009-04-09 21:54:50 +0000395- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
396 its clarity and its speed.
397
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000398- Issue #2396: the memoryview object was backported from Python 3.1.
399
Georg Brandld3f03fa2009-04-02 18:09:04 +0000400- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

Brett Cannon15ba4da2009-04-01 18:03:59 +0000403- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
404
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000405- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
406 the end sys.path, for compatibility with the system install of Python.
407
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000408- Issue #4688: Add a heuristic so that tuples and dicts containing only
409 untrackable objects are not tracked by the garbage collector. This can
410 reduce the size of collections and therefore the garbage collection overhead
411 on long-running programs, depending on their particular use of datatypes.
412
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000413- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
414 improve its performance. Long divisions and remainder operations
415 are now between 50% and 150% faster.
416
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000417- Issue #4258: Make it possible to use base 2**30 instead of base
418 2**15 for the internal representation of integers, for performance
419 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
420 --enable-big-digits option to configure, which overrides the
421 default. Add sys.long_info structseq to provide information about
422 the internal format.
423
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000424- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
425 result traceback.__members__ no longer exists.)
426
Mark Dickinson6b265f12009-03-18 16:07:26 +0000427- Issue #4474: PyUnicode_FromWideChar now converts characters outside
428 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
429 and sizeof(Py_UNICODE) == 2.
430
Eric Smith6f42edb2009-03-14 11:57:26 +0000431- Issue #5237: Allow auto-numbered fields in str.format(). For
432 example: '{} {}'.format(1, 2) == '1 2'.
433
Brett Cannon6c4cff02009-03-11 04:51:06 +0000434- Issue #3652: Make the 'line' argument for warnings.showwarning() a
435 requirement. Means the DeprecationWarning from Python 2.6 can go away.
436
Eric Smithe9fb6862009-02-20 14:02:36 +0000437- Issue #5247: Improve error message when unknown format codes are
438 used when using str.format() with str, unicode, long, int, and
439 float arguments.
440
Raymond Hettinger08259e82009-02-18 23:10:19 +0000441- Running Python with the -3 option now also warns about classic division
442 for ints and longs.
443
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000444- Issue #5260: Long integers now consume less memory: average
445 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
446 on a 64-bit system.
447
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000448- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
449 rotating the object pointer by 4 bits to the right.
450
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000451- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
452 it now forces its argument to double before testing for infinity.
453
Benjamin Petersone18ef192009-01-20 14:21:16 +0000454- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
455
Georg Brandl29c6a282009-04-05 20:23:13 +0000456- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000457 were suppressing all exceptions. These include list(), filter(), map(),
458 zip(), and bytearray().
459
Benjamin Peterson596d3062009-01-19 15:42:23 +0000460- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
461 functions.
462
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000463- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

467
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000468- Issue #4935: The overflow checking code in the expandtabs() method common
469 to str, bytes and bytearray could be optimized away by the compiler, letting
470 the interpreter segfault instead of raising an error.
471
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000472- Issue #3720: Fix a crash when an iterator modifies its class and removes its
473 __next__ method.

478
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000479- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
480 collecting the oldest generation) so that allocating lots of objects without
481 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000482 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000483 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

486
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000487- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
488 an existing .py counterpart, override the co_filename attributes of all
489 code objects if the original filename is obsolete (which can happen if the
490 file has been renamed, moved, or if it is accessed through different paths).
491 Patch by Ziga Seilnacht and Jean-Paul Calderone.
492
Martin v. Löwis5344c992009-01-02 20:32:55 +0000493- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000495- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
496 file with `str' filename on Windows.
497
Antoine Pitrouaa687902009-01-01 14:11:22 +0000498- Issue #3680: Reference cycles created through a dict, set or deque iterator
499 did not get collected.
500
Nick Coghlan180e4002008-12-30 01:18:48 +0000501- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
502 where the tp_hash and tp_dict slots are both NULL.
503
Benjamin Peterson7af65562008-12-29 17:56:58 +0000504- Issue #4764: With io.open, IOError.filename is set when trying to open a
505 directory on POSIX systems.
506
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000507- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
508 systems.
509

511 bytearray.translate(). It was always allowed for bytes.translate().
512
Skip Montanarof205c132008-12-23 03:30:15 +0000513- Added test case to ensure attempts to read from a file opened for writing
514 fail.
515
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000516- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
517 print elapsed times, not only when some objects are uncollectable /
518 unreachable. Original patch by Neil Schemenauer.
519
Mark Dickinson1a707982008-12-17 16:14:37 +0000520- Issue #3439: Add a bit_length method to int and long.

Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000525- Issue #4597: Fixed exception handling when the __exit__ function of a
526 context manager returns a value that cannot be converted to a bool.
527
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000528- Issue #4597: Fixed several opcodes that weren't always propagating
529 exceptions.
530
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000531- Issue #4445: Replace "sizeof(PyStringObject)" with
532 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
533 str instances. On a typical machine this saves 3 bytes of memory
534 (on average) per string allocation.
535
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000536- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
537 interpreter to abort ("Fatal Python error: Could not reset the stack!")
538 instead of throwing a MemoryError.
539
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000540- Issue #3689: The list reversed iterator now supports __length_hint__
541 instead of __len__. Behavior now matches other reversed iterators.
542
Benjamin Petersonc078f922008-11-21 22:27:24 +0000543- Issue #4367: Python would segfault during compiling when the unicodedata
544 module couldn't be imported and \N escapes were present.
545
Vinay Sajip213faca2008-12-03 23:22:58 +0000546- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000547 method on file objects with closefd=False. The file descriptor is still
548 kept open but the file object behaves like a closed file. The ``FileIO``
549 object also got a new readonly attribute ``closefd``.
550
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000551- Issue #4348: Some bytearray methods returned that didn't cause any change to
552 the bytearray, returned the same bytearray instead of a copy.
553
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000554- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

557
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000558- Issue #4048: The parser module now correctly validates relative imports.
559
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000560- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
561 exec statement.
562
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000563- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
564 method does not return iterators for the 4th and 5th items.
565
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000566- Issue #4209: Enabling unicode_literals and the print_function in the same
567 __future__ import didn't work.
568
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000569- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000570 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000571
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000572- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
573 returned a path longer than MAX_PATH. (But It's doubtful this code path is
574 really executed because I cannot move to such directory on win2k)
575
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000576- Issue #4069: When set.remove(element) is used with a set element, the element
577 is temporarily replaced with an equivalent frozenset. But the eventual
578 KeyError would always report the empty frozenset([]) as the missing key. Now
579 it correctly refers to the initial element.
580
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000581- Issue #4509: Various issues surrounding resize of bytearray objects to

597 returned them on 64bit platforms.
598
Walter Dörwalded960ac2009-05-03 22:36:33 +0000599- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
600 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
601 step. This avoids problems with counting UTF-8 bytes that ignores the effect

1847 leak-chasing test runs give sensible results. The previous method of
1848 reaping threads could return successfully while some Thread objects were
1849 still referenced. This also introduces a new private function:

1877 test_heapq and test_warnings have been adjusted to use it, tests for
1878 other modules with both C and Python implementations in the stdlib

1988-----------------
1989
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001990- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1991
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001992- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1993 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1994 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1995 ``printf`` function, whereas PyString_FromFormat has an independent
1996 implementation and uses "%zd" on all platforms for size_t values.
1997 This makes a difference on win64, where ``printf`` needs "%Id" to display
1998 64bit values.
1999
Benjamin Peterson97179b02008-09-09 20:55:01 +00002000- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2001 error.
2002
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002003- Issue #3777: long() applied to a float object now always return a long
2004 object; previously an int would be returned for small values. the __long__
2005 method is allowed to return either an int or a long, but the behaviour of
2006 float objects should not change to respect backward compatibility.
2007
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002008- Issue #3751: str.rpartition would perform a left-partition when called with
2009 a unicode argument.
2010
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002011- Issue #3683: Fix compilation when --without-threads is given.
2012
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002013- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002014 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002015 was correctly parsed but parsing of subsequent arguments failed.
2016
Vinay Sajip35e3b032008-09-01 14:33:59 +00002017- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002018 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2019 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2020 when given a tuple of classes as second argument, were looking up
2021 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2022 type object.
2023
Neal Norwitz18aa3882008-08-24 05:04:52 +00002024- Fix crashes on memory allocation failure found with failmalloc.
2025
2026- Fix memory leaks found with valgrind and update suppressions file.
2027
2028- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2029
2030- Fix problem using wrong name in decimal module reported by pychecker.
2031
Christian Heimes7d4c3172008-08-22 19:47:25 +00002032- Silenced another compiler warning about a used but not defined
2033 function 'stringlib_contains_obj'.
2034
Benjamin Peterson712ee922008-08-24 18:10:20 +00002035- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2036 ``__delslice__``.
2037
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002038- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2039 library targets in the Makefile.
2040
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002041- Issue #1204: The configure script now tests for additional libraries
2042 that may be required when linking against readline. This fixes issues
2043 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00002053- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
2054 stack usage in the case of deeply nested objects.
2055
Guido van Rossume3c4fd92008-09-10 14:27:00 +00002056- Issue #3629: Fix sre "bytecode" validator for an end case.

2065
Nick Coghland2e09382008-09-11 12:11:06 +00002066- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002067 return a list or None rather than a custom object.
2068
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002069- Issue #1638033: Cookie.Morsel gained the httponly attribute.
2070

2093 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2094 for catch_warnings() also led to an improvement in the raising of a
2095 DeprecationWarning related to warnings.warn_explicit().
2096
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002097- The deprecation warnings for the old camelCase threading API were removed.

2119
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002120- Issue #2975: When compiling several extension modules with Visual Studio 2008
2121 from the same python interpreter, some environment variables would grow
2122 without limit.
2123
Benjamin Peterson37346b22008-08-23 20:27:43 +00002124- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2125 exploitation of poor argument checking.
2126
Gerhard Häringef2276b2008-09-12 13:54:06 +00002127- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
2128
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00002129- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
2130 remaining ones have "pysqlite_" prefix.
2131
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002132- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

2140 wrapper for warnings.catch_warnings() that makes it easier to check
2141 that expected warning messages are being reported.
2142
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002143- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002161What's New in Python 2.6 beta 3?
2162================================
2163
Barry Warsaw07a4a382008-08-21 01:15:08 +00002164*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002165
2166Core and Builtins
2167-----------------
2168
Guido van Rossumf8402962008-08-20 15:01:50 +00002169- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2170 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2171 extensions do not automatically benefit from the class attribute
2172 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2173 to their tp_flags field if they care. This is a backwards
2174 compatibility feature; in 3.0, all types will use the cache by
2175 default.
2176
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002177- Keyword arguments can now follow starred arguments. (``f(a, *args,
2178 keyword=23)`` is now valid syntax.)
2179
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002180- ctypes function pointers that are COM methods have a boolean True
2181 value again.
2182
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002183- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2184 by denying s# to parse objects that have a releasebuffer procedure,
2185 and introducing s*.
2186
Georg Brandl1e13ea92008-08-11 09:07:59 +00002187- Issue #3537: Fix an assertion failure when an empty but presized dict
2188 object was stored in the freelist.
2189
Mark Dickinsonb6467572008-08-04 21:30:09 +00002190- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2191 ValueError consistently across platforms.
2192
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002193- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2194 (64bit Unix, for example), unichr() would truncate its argument and return
2195 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2196
Neal Norwitze7d8be82008-07-31 17:17:14 +00002197- Apply security patches from Apple.
2198
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002199- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2200 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2201
Antoine Pitrou92f82162008-07-25 22:22:08 +00002202- Issue #1819: function calls with several named parameters are now on
2203 average 35% faster (as measured by pybench).
2204
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002205- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2206 the python debugger steps into a class statement: the free variables (local
2207 variables defined in an outer scope) would be deleted from the outer scope.
2208
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002209- Issue #2620: Overflow checking when allocating or reallocating memory
2210 was not always being done properly in some python types and extension
2211 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2212 all been updated to perform better checks and places in the code that
2213 would previously leak memory on the error path when such an allocation
2214 failed have been fixed.

2217-------
2218
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002219- Issue #3612: Added some missing basic types in ctypes.wintypes.
2220
Benjamin Petersone977ad42008-08-20 01:42:01 +00002221- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2222 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2223
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002224- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2225 version reported by these tools does not necessarily follow the python
2226 version numbering scheme, so the module is less strict when parsing it.
2227
Nick Coghlanf70385a2008-08-18 12:42:46 +00002228- Issue #2235: Added Py3k warnings for types which will become unhashable
2229 under the stricter __hash__ inheritance rules in 3.0. Several types
2230 which did not meet the rules for hash invariants and were already
2231 unhashable in 3.0 have now been explicitly flagged as unhashable in
2232 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2233 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2234
Brett Cannon88f801d2008-08-18 00:46:22 +00002235- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2236 imported into the module but exposed as part of the module's API.
2237
Brett Cannon7b96f072008-08-18 00:41:11 +00002238- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2239
Brett Cannon46225e72008-08-18 00:36:52 +00002240- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002242- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2243
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002244- Issue #3575: Incremental decoder's decode function now takes bytearray
2245 by using 's*' instead of 't#'.
2246
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002247- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002248 fails unicode conversion on 2nd parameter. (windows only)
2249
Facundo Batista94f243a2008-08-17 03:38:39 +00002250- Issue 2464. urllib2 now supports a malformation in the URL received
2251 in a redirect.
2252
Brett Cannonabe423e2008-08-16 21:47:07 +00002253- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002254 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002255
Facundo Batistaeb90b782008-08-16 14:44:07 +00002256- Issue #2776: fixed small issue when handling an URL with double slash
2257 after a 302 response in the case of not going through a proxy.
2258
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002259- Issue #2676: in the email package, content-type parsing was hanging on
2260 pathological input because of quadratic or exponential behaviour of a
2261 regular expression.
2262
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002263- Issue #3476: binary buffered reading through the new "io" library is now
2264 thread-safe.
2265
Brett Cannonbf3157b2008-08-14 05:00:03 +00002266- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2267 since mimetools itself is deprecated. Because modules are cached, all
2268 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2269
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002270- Issue #3134: shutil referenced undefined WindowsError symbol.
2271
Robert Schuppenies14646332008-08-10 11:01:53 +00002272- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2273 menu entries were not deleted.
2274
Brett Cannon83e81842008-08-09 23:30:55 +00002275- Copied the implementation of reduce() to _functools.reduce() to have a

Antoine Pitroude781a42008-08-09 12:43:23 +00002304 asking for a specific length. This problem only affected files opened

2348
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002349- Issue #643841: The language reference now provides more detailed

2361-----------------
2362
Georg Brandl3e483f62008-07-16 22:57:41 +00002363- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2364 its methods now allow for items objects that can be converted to
2365 an integer using operator.index().
2366
Mark Dickinson64b7e502008-07-16 09:40:03 +00002367- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2368 produced a ValueError instead of giving the correct float.
2369
Eric Smitha5fa5a22008-07-16 00:11:49 +00002370- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2371 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2372
Mark Dickinson7103aa42008-07-15 19:08:33 +00002373- Issue #3008: the float type has a new instance method 'float.hex'
2374 and a new class method 'float.fromhex' to convert floating-point
2375 numbers to and from hexadecimal strings, respectively.
2376
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002377- Issue #2235: __hash__ is once again inherited by default. To allow
2378 collections.Hashable to remain meaningful in the presence of the
2379 default hash implementation (object.__hash__), it is now possible
2380 to explicit block inheritance of hash by setting __hash__=None at
2381 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2382 level.
2383
Nick Coghlanb028f502008-07-13 14:52:36 +00002384- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2385 the parent module cannot be found while performing an absolute import.
2386 This means that an incorrectly defined __package__ attribute will
2387 now only prevent relative imports in that module rather than causing
2388 all imports from that module to fail.
2389
Nick Coghlan14ff9942008-07-08 14:21:42 +00002390- Issue #2517: Allow unicode messages in Exceptions again by correctly

2399 threading.local: the first member set by a thread could be saved in
2400 another thread's dictionary.
2401
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002402- Issue #3004: Minor change to slice.indices(): the start and stop
2403 arguments are now treated identically, making the behaviour easier
2404 to describe and understand. For example, slice(None, -10,
2405 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2406 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2407 10, -1).
2408
Georg Brandl278fc502008-07-19 12:46:12 +00002409- Issue #3219: Calling a function with repeated keyword arguments,
2410 f(a=2, a=23), would not cause a syntax error. This was a regression
2411 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002412
Georg Brandl278fc502008-07-19 12:46:12 +00002413- Issue #2862: Make int and float freelist management consistent with
2414 other freelists. Changes their CompactFreeList apis into
2415 ClearFreeList apis and calls them via gc.collect().

2421 api functions without holding the GIL, which could lead to a fatal
2422 error when they failed.
2423
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002424- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002449- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2450 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002451 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002452 content-length. The problem had been corrected in the 2.4 branch, but never
2453 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002468- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Martin v. Löwis8c255e42008-05-23 15:06:50 +00002855- Patch #1722225: Support QNX 6.
2856
Brett Cannonb61d8012008-05-11 23:39:04 +00002857- ``Lib/lib-old`` is now added to sys.path.
2858
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002859- On MacOS X it is now possible to install the framework in 64-bit
2860 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002861 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002862
2863 This is controlled by the configure argument ``--with-universal-archs``:
2864
2865 - ``--with-universal-archs=all``: install 4-way universal
2866
2867 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2868
2869 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2870
2871 This option should be used in combination with ``--enable-universalsdk=``.
2872
2873 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00002882
2883- The PyString functions have been renamed to PyBytes. A batch of
2884 defines were added so that the linker still sees the original
2885 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002923- Issue #1631171: Re-implement the 'warnings' module in C (the
2924 original Python code has been kept as backup). This will allow for
2925 using the 'warning's machinery in such places as the parser where
2926 use of pure Python code is not possible. Both the ``showarning()``
2927 and ``formatwarning()`` gain an optional 'line' argument which is
2928 not called by default for backwards-compatibility reasons. Setting
2929 ``warnings.showwarning()`` to an implementation that lacks support
2930 for the ``line`` argument will raise a DeprecationWarning.

2954
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002955- The getpass module has been improved on Unix. It now uses /dev/tty
2956 by default and uses stderr instead of stdout. A GetPassWarning is
2957 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002958
Skip Montanarob131f042008-04-18 20:35:46 +00002959- Issue #2014: Allow XML-RPC datetime objects to have dates before

2969 implementation detail of the public ``types`` module, has been
2970 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00002971
Georg Brandl3ee81df2008-05-17 18:14:43 +00002972- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002973 extension modules between 32 and 64 bit platforms. See the distutls
2974 build documentation for more information.
2975
Gregory P. Smithaa63d0d2008-04-06 23:11:17 +00002976- Issue #815646: Individual file objects may now be used from multiple
2977 threads at once without fear of crashing the Python interpreter. If
2978 file.close() is called while an object is in use by another thread
2979 an IOError exception will be raised and the file will not be closed.
2980
Thomas Hellerf7906482008-04-04 19:43:25 +00002981- The bundled libffi copy is now in sync with the recently released

2983 Modules/_ctypes/libffi/configure.ac.
2984
Georg Brandl3ee81df2008-05-17 18:14:43 +00002985- Issue #2385: distutils.core.run_script() makes __file__ available,
2986 so the controlled environment will more closely mirror the typical
2987 script environment. This supports setup.py scripts that refer to
2988 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002993- Issue #2550: The approach used by client/server code for obtaining
2994 ports to listen on in network-oriented tests has been refined in an
2995 effort to facilitate running multiple instances of the entire
2996 regression test suite in parallel without issue.
2997 test_support.bind_port() has been fixed such that it will always
2998 return a unique port -- which wasn't always the case with the
2999 previous implementation, especially if socket options had been set
3000 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3001 new implementation of bind_port() will actually raise an exception
3002 if it is passed an AF_INET/SOCK_STREAM socket with either the
3003 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3004 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3005 the socket it's been passed. This currently only applies to
3006 Windows. This option prevents any other sockets from binding to the
3007 host/port we've bound to, thus removing the possibility of the
3008 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3009 when a second SOCK_STREAM socket binds and accepts to a host/port
3010 that's already been bound by another socket. The optional preferred
3011 port parameter to bind_port() has been removed. Under no
3012 circumstances should tests be hard coding ports!
3013
3014 test_support.find_unused_port() has also been introduced, which will
3015 pass a temporary socket object to bind_port() in order to obtain an
3016 unused port. The temporary socket object is then closed and
3017 deleted, and the port is returned. This method should only be used
3018 for obtaining an unused port in order to pass to an external program
3019 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3020 a parameter to a server-oriented class that doesn't give you direct
3021 access to the underlying socket used.
3022
3023 Finally, test_support.HOST has been introduced, which should be used
3024 for the host argument of any relevant socket calls (i.e. bind and
3025 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003026
3027 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003028 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003029 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3030 test_asynchat and test_socket_ssl.
3031
Georg Brandl3ee81df2008-05-17 18:14:43 +00003032 It is now possible for multiple instances of the regression test
3033 suite to run in parallel without issue.

3300-----------------
3301
Fred Drakea8ee94b2008-03-01 02:45:07 +00003302- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003303 644. The mode is now inherited from the py file.

3306
3307- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003308
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003309- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003310 issue 215555 for a discussion.
3311
Eric Smitha73fbe72008-02-23 03:09:44 +00003312- Added the future_builtins module, which contains hex() and oct().
3313 These are the PEP 3127 version of these functions, designed to be
3314 compatible with the hex() and oct() builtins from Python 3.0. They
3315 differ slightly in their output formats from the existing, unchanged
3316 Python 2.6 builtins. The expected usage of the future_builtins
3317 module is:
3318 from future_builtins import hex, oct
3319
Eric Smith7ef40bf2008-02-20 23:34:22 +00003320- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3321 exponents for exponents with absolute value < 100. Follows C99
3322 standard. This is a change on Windows, which would use 3 digits.
3323 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3324 so that any alterations it does to the resulting string will be
3325 available in stringlib/formatter.h (for float.__format__).
3326
Eric Smith5a3c1352008-02-19 13:21:56 +00003327- Implemented PEP 3101, Advanced String Formatting. This adds a new
3328 builtin format(); a format() method for str and unicode; a
3329 __format__() method to object, str, unicode, int, long, float, and
3330 datetime; the class string.Formatter; and the C API
3331 PyObject_Format().
3332
Georg Brandl3ee81df2008-05-17 18:14:43 +00003333- Fixed several potential crashes, all caused by specially crafted
3334 __del__ methods exploiting objects in temporarily inconsistent
3335 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003336
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003337- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003338 prevent a possible crash: an Abstract Base Class would try to access
3339 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003344- Clear all free lists during a gc.collect() of the highest generation
3345 in order to allow pymalloc to free more arenas. Python may give back
3346 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003347
Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Issue #2045: Fix an infinite recursion triggered when printing a
3349 subclass of collections.defaultdict, if its default_factory is set
3350 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003351
Christian Heimesf75dbef2008-02-08 00:11:31 +00003352- Fixed a minor memory leak in dictobject.c. The content of the free
3353 list was not freed on interpreter shutdown.
3354
Georg Brandl3ee81df2008-05-17 18:14:43 +00003355- Limit free list of method and builtin function objects to 256
3356 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003357
Georg Brandl3ee81df2008-05-17 18:14:43 +00003358- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3359 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003360 to compact the internal free lists of pre-allocted ints and floats.
3361
Georg Brandl3ee81df2008-05-17 18:14:43 +00003362- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3363 calls. Python expected the return type int but the fork familie
3364 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003365
Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003375- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3376 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003377
Georg Brandl3ee81df2008-05-17 18:14:43 +00003378- Patch #1473257: generator objects gain a gi_code attribute. This is
3379 the same object as the func_code attribute of the function that
3380 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003381
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382- Issue #1920: "while 0" statements were completely removed by the
3383 compiler, even in the presence of an "else" clause, which is
3384 supposed to be run when the condition is false. Now the compiler
3385 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003386
Guido van Rossumeead05f2008-01-24 18:21:02 +00003387- A few crashers fixed: weakref_in_del.py (issue #1377858);
3388 loosing_dict_ref.py (issue #1303614, test67.py);
3389 borrowed_ref_[34].py (not in tracker).
3390
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003391- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003392 suppressed while an extension is loaded by calling SetErrorMode in
3393 dynload_win.c. The error is still reported properly.
3394
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003396 several extension methods and modules do not work without unicode
3397 support.
3398
Georg Brandl26543b12008-01-21 18:36:51 +00003399- Issue #1882: when compiling code from a string, encoding cookies in the
3400 second line of code were not always recognized correctly.
3401
Georg Brandl14404b62008-01-19 19:27:05 +00003402- Issue #1679: "0x" was taken as a valid integer literal.
3403
Georg Brandl6caad7d2008-01-26 14:19:22 +00003404- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003405 added.
3406
Christian Heimesc94e2b52008-01-14 04:13:37 +00003407- sys.float_info / PyFloat_GetInfo: The floating point information
3408 object was converted from a dict to a specialized structseq object.
3409
Georg Brandl3ee81df2008-05-17 18:14:43 +00003410- Patch #1816: Added sys.flags structseq. It exposes the status of
3411 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003412
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413- Objects/structseq.c: Implemented new structseq representation. The
3414 patch makes structseqs (e.g. the return value of os.stat) more
3415 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003416
Georg Brandl3ee81df2008-05-17 18:14:43 +00003417- Patch #1700288: added a type attribute cache that caches method
3418 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003419
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003420- Bug #1776: __import__() no longer accepts filenames on any platform.
3421 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003422
Georg Brandlaed6c662008-01-07 17:25:53 +00003423- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3424
Georg Brandl3ee81df2008-05-17 18:14:43 +00003425- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3426 envvar and sys.dont_write_bytecode attribute. All these can be set
3427 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Improve some exception messages when Windows fails to load an
3430 extension module. Now we get for example '%1 is not a valid Win32
3431 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003432

Christian Heimes0a8143f2007-12-18 23:22:54 +00003438- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003439 and INF. float("nan"), float("inf") and float("-inf") now work on
3440 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003441
Georg Brandl3ee81df2008-05-17 18:14:43 +00003442- Compiler now generates simpler and faster code for dictionary
3443 literals. The oparg for BUILD_MAP now indicates an estimated
3444 dictionary size. There is a new opcode, STORE_MAP, for adding
3445 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003474- Patch #1739468: Directories and zipfiles containing a __main__.py
3475 file can now be directly executed by passing their name to the
3476 interpreter. The directory/zipfile is automatically inserted as the
3477 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003478
Georg Brandl3ee81df2008-05-17 18:14:43 +00003479- Issue #1265: Fix a problem with sys.settrace, if the tracing
3480 function uses a generator expression when at the same time the
3481 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003482
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003483- sets and frozensets now have an isdisjoint() method.
3484

3486
Neal Norwitz44f326e2007-10-05 05:29:17 +00003487- Fix warnings found by the new version of the Coverity checker.
3488
Georg Brandl3ee81df2008-05-17 18:14:43 +00003489- The enumerate() builtin function is no longer bounded to sequences
3490 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3491 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003492
Georg Brandl3ee81df2008-05-17 18:14:43 +00003493- Issue #1686386: Tuple's tp_repr did not take into account the
3494 possibility of having a self-referential tuple, which is possible
3495 from C code. Nor did object's tp_str consider that a type's tp_str
3496 could do something that could lead to an inifinite recursion.
3497 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3498 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003499
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Issue #1164: It was possible to trigger deadlock when using the
3501 'print' statement to write to a file since the GIL was not released
3502 as needed. Now PyObject_Print() does the right thing along with
3503 various tp_print implementations of the built-in types and those in
3504 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003505
Georg Brandl3ee81df2008-05-17 18:14:43 +00003506- Issue #1147: Exceptions were directly allowing string exceptions in
3507 their throw() method even though string exceptions no longer
3508 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003509
Georg Brandl3ee81df2008-05-17 18:14:43 +00003510- Issue #1096: Prevent a segfault from getting the repr of a very
3511 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003512
Brett Cannon1e534b52007-09-07 04:18:30 +00003513- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514 PyObject_Call() never calling back out to Python code to trigger
3515 recursion depth updates/checks. Required the creation of a static
3516 RuntimeError instance in case normalizing an exception put the
3517 recursion check value past its limit. Fixes crashers
3518 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003519
Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003533- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003534 __*__ attributes. (Some already existed, e.g., __doc__ and
3535 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003536
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003537- Add -3 option to the interpreter to warn about features that are
3538 deprecated and will be changed/removed in Python 3.0.
3539
Georg Brandl2134e752007-05-21 20:34:16 +00003540- Patch #1686487: you can now pass any mapping after '**' in function
3541 calls.
3542
Collin Winter62903052007-05-18 23:11:24 +00003543- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003544 "except E as target:". This is to provide forwards compatibility
3545 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003546
Brett Cannon229cee22007-05-05 01:34:02 +00003547- Deprecate BaseException.message as per PEP 352.
3548
Georg Brandl3ee81df2008-05-17 18:14:43 +00003549- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003550 inherited from a builtin base.
3551
Vinay Sajip8549ce32007-05-06 17:53:37 +00003552- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003553 setting a plain string, ie don't expand to single letter identifiers.
3554
Raymond Hettinger13936692007-04-11 18:40:58 +00003555- Request #1191699: Slices can now be pickled.
3556
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003557- Request #1193128: str.translate() now allows a None argument for
3558 translations that only remove characters without re-mapping the
3559 remaining characters.
3560
Georg Brandl5cb76c12007-03-21 09:00:39 +00003561- Patch #1682205: a TypeError while unpacking an iterable is no longer
3562 masked by a generic one with the message "unpack non-sequence".
3563
Neal Norwitzaa754b72007-03-21 06:39:48 +00003564- Remove unused file Python/fmod.c.
3565
Guido van Rossum143b5642007-03-23 04:58:42 +00003566- Bug #1683368: The object.__init__() and object.__new__() methods are
3567 now stricter in rejecting excess arguments. The only time when
3568 either allows excess arguments is when it is not overridden and the
3569 other one is. For backwards compatibility, when both are
3570 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003571 warning later). Also, type.__init__() insists on the same signature
3572 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3575 object to complex using its __complex__() method before falling back
3576 to the __float__() method. Therefore, the functions in the cmath
3577 module now can operate on objects that define a __complex__()
3578 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003579
Georg Brandl3ee81df2008-05-17 18:14:43 +00003580- Patch #1623563: allow __class__ assignment for classes with
3581 __slots__. The old and the new class are still required to have the
3582 same slot names.

3588 ``object.__reduce_ex__()`` is called with an object that is faking
3589 its type.

3595
Georg Brandl7b9c5552007-03-12 14:30:05 +00003596- Bug #1678647: write a newline after printing an exception in any
3597 case, even when converting the value to a string failed.
3598
Georg Brandl871f1bc2007-03-12 13:17:36 +00003599- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003600 its argument, if it exists. If not, it will work like before. This
3601 allows customizing the output of dir() in the presence of a
3602 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00003604- Patch #922167: Python no longer segfaults when faced with infinitely
3605 self-recursive reload() calls (as reported by bug #742342).
3606
Georg Brandl3ee81df2008-05-17 18:14:43 +00003607- Patch #1675981: remove unreachable code from ``type.__new__()``

Facundo Batistad918a652007-04-24 13:54:38 +00004125- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004126 the client's request was successfully received, understood, and
4127 accepted. Now in these cases no error is raised in urllib (issue
4128 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004129

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004136- Added a timeout parameter to the constructor of other protocols
4137 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4138 work started with create_connection() and timeout in httplib, and
4139 closes patch #723312.
4140
Vinay Sajip8549ce32007-05-06 17:53:37 +00004141- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista07c78be2007-03-23 18:54:07 +00004144

4165
Georg Brandlf66b6032007-03-14 08:27:52 +00004166- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004167 AttributeError instead of an IOError when the server's response
4168 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004169
Georg Brandl3ee81df2008-05-17 18:14:43 +00004170- Patch #957650: "%var%" environment variable references are now
4171 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00004174- Patch #1429539: pdb now correctly initializes the __main__ module
4175 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004176 correctly now.
4177
Georg Brandlbad6f192007-03-13 21:32:56 +00004178- The nonobvious commands.getstatus() function is now deprecated.

4184
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185- Patch #1530482: add pydoc.render_doc() which returns the
4186 documentation for a thing instead of paging it to stdout, which
4187 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004188

Georg Brandl9e6b4702007-03-13 18:15:41 +00004198- Patch #1581073: add a flag to textwrap that prevents the dropping of

4200
Georg Brandl92a6bae2007-03-13 17:43:32 +00004201- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004202 are set for invalid interpolation sequences that would lead to
4203 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004204

Georg Brandl3ee81df2008-05-17 18:14:43 +00004219 field names in its exception message if you try to write a record
4220 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004238

4257
Georg Brandl3ee81df2008-05-17 18:14:43 +00004258- unittest now verifies more of its assumptions. In particular,
4259 TestCase and TestSuite subclasses (not instances) are no longer
4260 accepted in TestSuite.addTest(). This should cause no
4261 incompatibility since it never made sense with ordinary subclasses
4262 -- the failure just occurred later, with a more cumbersome
4263 exception.

4272 given a unicode argument and os.listdir() returns unicode filenames.
4273
Georg Brandl3ee81df2008-05-17 18:14:43 +00004274- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004652 time so that opening a database previously created with the DB_DUP
4653 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4654 opens. Specifically: dictionary assignment to a DB object will
4655 replace all values for a given key when the database allows
4656 duplicate values. DB users should use DB.put(k, v) when they want
4657 to store duplicates; not DB[k] = v.

4664 characters with ASCII value less than 32. Also, it correctly quotes
4665 dots only if they occur on a single line, as opposed to the previous
4666 behavior of quoting dots if they are the second character of any
4667 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004668
