63
Benjamin Petersonc4771d22009-12-13 17:31:31 +000064- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

112Core and Builtins
113-----------------
114
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000115- Issue #7419: setlocale() could crash the interpreter on Windows when called
116 with invalid values.
117
Eric Smithc4ab8332009-11-29 17:40:57 +0000118- Issue #3382: 'F' formatting for float and complex now convert the
119 result to upper case. This only affects 'inf' and 'nan', since 'f'
120 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000121
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000122- Remove switch from "%f" formatting to "%g" formatting for floats
123 larger than 1e50 in absolute value.
124
Mark Dickinson18cfada2009-11-23 18:46:41 +0000125- Remove restrictions on precision when formatting floats. E.g.,
126 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
127 requested 120 significant digits instead.
128
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000129- Add Py3k warnings for parameter names in parenthesis.
130
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000131- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000132
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000133- Issue #7085: Fix crash when importing some extensions in a thread
134 on MacOSX 10.6.
135
Mark Dickinsonb678de82009-11-19 18:41:49 +0000136- Issue #7117: repr(x) for a float x returns a result based on the
137 shortest decimal string that's guaranteed to round back to x under
138 correct rounding (with round-half-to-even rounding mode).
139 Previously it gave a string based on rounding x to 17 decimal digits.
140 repr(x) for a complex number behaves similarly. On platforms where
141 the correctly-rounded strtod and dtoa code is not supported (see below),
142 repr is unchanged.
143
144- Issue #7117: On almost all platforms: float-to-string and
145 string-to-float conversions within Python are now correctly rounded.
146 Places these conversions occur include: str for floats and complex
147 numbers; the float and complex constructors; old-style and new-style
148 numeric formatting; serialization and deserialization of floats and
149 complex numbers using marshal, pickle and json; parsing of float and
150 imaginary literals in Python code; Decimal-to-float conversion.
151
152 The conversions use a Python-adapted version of David Gay's
153 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
154 functions. This code is supported on Windows, and on Unix-like
155 platforms using gcc, icc or suncc as the C compiler. There may be a
156 small number of platforms on which correct operation of this code
157 cannot be guaranteed, so the code is not used: notably, this applies
158 to platforms where the C double format is not IEEE 754 binary64, and
159 to platforms on x86 hardware where the x87 FPU is set to 64-bit
160 precision and Python's configure script is unable to determine how
161 to change the FPU precision. On these platforms conversions use the
162 platform strtod and dtoa, as before.
163
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000164- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000165 now uses the correctly-rounded string <-> float conversions
166 described above (when available), and so produces correctly rounded
167 results that will display nicely under the float repr. There are
168 two related small changes: (1) round now accepts any class with an
169 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000170 floats for the second argument), and (2) an excessively large second
171 integer argument (e.g., round(1.234, 10**100)) no longer raises an
172 exception.
173
Philip Jenveyfab8be22009-11-17 02:42:26 +0000174- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
175
Benjamin Petersone36199b2009-11-12 23:39:44 +0000176- Fix several issues with compile(). The input can now contain Windows and Mac
177 newlines and is no longer required to end in a newline.
178

180 unicode string.
181
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000182- Issue #7244: itertools.izip_longest() no longer ignores exceptions

190
Eric Smithc12781a2009-10-19 14:38:14 +0000191- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

202 Patch by Christopher Tur Lesniewski-Laas.
203
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000204- Issue #7084: Fix a (very unlikely) crash when printing a list from one

R. David Murray525cffc2009-05-13 13:07:14 +0000312- Issue #5994: the marshal module now has docstrings.
313
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000314- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
315 (1) inf and nan strings with trailing whitespace were incorrectly
316 rejected; (2) parsing of strings representing infinities and nans
317 was locale aware; and (3) the interpretation of fromhex('-nan')
318 didn't match that of float('-nan').
319
Eric Smitha985a3a2009-05-05 18:26:08 +0000320- Issue #5920: For float.__format__, change the behavior with the
321 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
322 to be like 'g' but with at least one decimal point and with a
323 default precision of 12. Previously, the behavior the same but with
324 a default precision of 6. This more closely matches str(), and
325 reduces surprises when adding alignment flags to the empty
326 presentation type. This also affects the new complex.__format__ in
327 the same way.
328
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000329- Issue #5890: in subclasses of 'property' the __doc__ attribute was
330 shadowed by classtype's, even if it was None. property now
331 inserts the __doc__ into the subclass instance __dict__.
332
Antoine Pitrou653dece2009-05-04 18:32:32 +0000333- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
334 sequences. Patch by Nick Barnes and Victor Stinner.
335
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000336- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000337 format(complex(1, 2./3), '.5') now produces a sensible result.
338
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000339- Issue #5864: Fix empty format code formatting for floats so that it
340 never gives more than the requested number of significant digits.
341
Eric Smithcac7af62009-04-27 19:04:37 +0000342- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

346 titlecase, but not their own uppercase.
347
Eric Smith068f0652009-04-25 21:40:15 +0000348- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
349 _PyOS_double_to_string or PyOS_double_to_string.
350
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000351- Issue #5283: Setting __class__ in __del__ caused a segfault.
352
Mark Dickinson95bc9802009-04-24 12:46:53 +0000353- Issue #5816: complex(repr(z)) now recovers z exactly, even when
354 z involves nans, infs or negative zeros.
355
Eric Smithaca19e62009-04-22 13:29:05 +0000356- Implement PEP 378, Format Specifier for Thousands Separator, for
357 floats, ints, and longs.
358
359- Issue #5515: 'n' formatting for ints, longs, and floats handles
360 leading zero formatting poorly.
361
362- Issue #5772: For float.__format__, don't add a trailing ".0" if
363 we're using no type code and we have an exponent.
364

369 some builtin types.
370
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000371- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000372 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000373

387
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000388- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
389 the end sys.path, for compatibility with the system install of Python.
390
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000391- Issue #4688: Add a heuristic so that tuples and dicts containing only
392 untrackable objects are not tracked by the garbage collector. This can
393 reduce the size of collections and therefore the garbage collection overhead
394 on long-running programs, depending on their particular use of datatypes.
395
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000396- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
397 improve its performance. Long divisions and remainder operations
398 are now between 50% and 150% faster.
399
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000400- Issue #4258: Make it possible to use base 2**30 instead of base
401 2**15 for the internal representation of integers, for performance
402 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
403 --enable-big-digits option to configure, which overrides the
404 default. Add sys.long_info structseq to provide information about
405 the internal format.
406
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000407- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
408 result traceback.__members__ no longer exists.)
409
Mark Dickinson6b265f12009-03-18 16:07:26 +0000410- Issue #4474: PyUnicode_FromWideChar now converts characters outside
411 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
412 and sizeof(Py_UNICODE) == 2.
413
Eric Smith6f42edb2009-03-14 11:57:26 +0000414- Issue #5237: Allow auto-numbered fields in str.format(). For
415 example: '{} {}'.format(1, 2) == '1 2'.
416
Brett Cannon6c4cff02009-03-11 04:51:06 +0000417- Issue #3652: Make the 'line' argument for warnings.showwarning() a
418 requirement. Means the DeprecationWarning from Python 2.6 can go away.
419
Eric Smithe9fb6862009-02-20 14:02:36 +0000420- Issue #5247: Improve error message when unknown format codes are
421 used when using str.format() with str, unicode, long, int, and
422 float arguments.
423
Raymond Hettinger08259e82009-02-18 23:10:19 +0000424- Running Python with the -3 option now also warns about classic division
425 for ints and longs.
426
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000427- Issue #5260: Long integers now consume less memory: average
428 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
429 on a 64-bit system.
430
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000431- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
432 rotating the object pointer by 4 bits to the right.
433
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000434- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
435 it now forces its argument to double before testing for infinity.
436
Benjamin Petersone18ef192009-01-20 14:21:16 +0000437- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
438
Georg Brandl29c6a282009-04-05 20:23:13 +0000439- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000440 were suppressing all exceptions. These include list(), filter(), map(),
441 zip(), and bytearray().
442
Benjamin Peterson596d3062009-01-19 15:42:23 +0000443- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
444 functions.
445
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000446- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
447 OSError.

450
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000451- Issue #4935: The overflow checking code in the expandtabs() method common
452 to str, bytes and bytearray could be optimized away by the compiler, letting
453 the interpreter segfault instead of raising an error.
454
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000455- Issue #3720: Fix a crash when an iterator modifies its class and removes its
456 __next__ method.
457
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000458- Issue #4893: Use NT threading on CE.

461
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000462- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
463 collecting the oldest generation) so that allocating lots of objects without
464 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000465 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000466 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

469
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000470- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
471 an existing .py counterpart, override the co_filename attributes of all
472 code objects if the original filename is obsolete (which can happen if the
473 file has been renamed, moved, or if it is accessed through different paths).
474 Patch by Ziga Seilnacht and Jean-Paul Calderone.
475
Martin v. Löwis5344c992009-01-02 20:32:55 +0000476- Issue #4075: Use OutputDebugStringW in Py_FatalError.
477
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000478- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
479 file with `str' filename on Windows.
480
Antoine Pitrouaa687902009-01-01 14:11:22 +0000481- Issue #3680: Reference cycles created through a dict, set or deque iterator
482 did not get collected.
483
Nick Coghlan180e4002008-12-30 01:18:48 +0000484- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
485 where the tp_hash and tp_dict slots are both NULL.
486
Benjamin Peterson7af65562008-12-29 17:56:58 +0000487- Issue #4764: With io.open, IOError.filename is set when trying to open a
488 directory on POSIX systems.
489
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000490- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
491 systems.
492
Georg Brandl6425a2f2008-12-28 11:54:53 +0000493- Issue #4759: None is now allowed as the first argument of
494 bytearray.translate(). It was always allowed for bytes.translate().
495
Skip Montanarof205c132008-12-23 03:30:15 +0000496- Added test case to ensure attempts to read from a file opened for writing
497 fail.
498
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000499- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
500 print elapsed times, not only when some objects are uncollectable /
501 unreachable. Original patch by Neil Schemenauer.
502
Mark Dickinson1a707982008-12-17 16:14:37 +0000503- Issue #3439: Add a bit_length method to int and long.

506 Original patch by Neal Norwitz.
507
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000508- Issue #4597: Fixed exception handling when the __exit__ function of a
509 context manager returns a value that cannot be converted to a bool.
510
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000511- Issue #4597: Fixed several opcodes that weren't always propagating
512 exceptions.
513
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000514- Issue #4445: Replace "sizeof(PyStringObject)" with
515 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
516 str instances. On a typical machine this saves 3 bytes of memory
517 (on average) per string allocation.
518
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000519- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
520 interpreter to abort ("Fatal Python error: Could not reset the stack!")
521 instead of throwing a MemoryError.
522
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000523- Issue #3689: The list reversed iterator now supports __length_hint__
524 instead of __len__. Behavior now matches other reversed iterators.
525
Benjamin Petersonc078f922008-11-21 22:27:24 +0000526- Issue #4367: Python would segfault during compiling when the unicodedata
527 module couldn't be imported and \N escapes were present.
528
Vinay Sajip213faca2008-12-03 23:22:58 +0000529- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000530 method on file objects with closefd=False. The file descriptor is still
531 kept open but the file object behaves like a closed file. The ``FileIO``
532 object also got a new readonly attribute ``closefd``.
533
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000534- Issue #4348: Some bytearray methods returned that didn't cause any change to
535 the bytearray, returned the same bytearray instead of a copy.
536
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000537- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
538

540
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000541- Issue #4048: The parser module now correctly validates relative imports.
542
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000543- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
544 exec statement.
545
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000546- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
547 method does not return iterators for the 4th and 5th items.
548
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000549- Issue #4209: Enabling unicode_literals and the print_function in the same
550 __future__ import didn't work.
551
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000552- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000553 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000554
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000555- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
556 returned a path longer than MAX_PATH. (But It's doubtful this code path is
557 really executed because I cannot move to such directory on win2k)
558
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000559- Issue #4069: When set.remove(element) is used with a set element, the element
560 is temporarily replaced with an equivalent frozenset. But the eventual
561 KeyError would always report the empty frozenset([]) as the missing key. Now
562 it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000579- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
580 returned them on 64bit platforms.
581
Walter Dörwalded960ac2009-05-03 22:36:33 +0000582- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
583 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
584 step. This avoids problems with counting UTF-8 bytes that ignores the effect
585 of using the replace error handler in PyUnicode_DecodeUTF8().
586
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000587- Issue #3739: The unicode-internal encoder now reports the number of characters
588 consumed like any other encoder (instead of the number of bytes).
589
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000590- Issue #2422: When compiled with the ``--with-valgrind`` option, the
591 pymalloc allocator will be automatically disabled when running under
592 Valgrind. This gives improved memory leak detection when running
593 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou59c44f32009-10-30 17:07:08 +00001829- Issue #7222: Make thread "reaping" more reliable so that reference
1830 leak-chasing test runs give sensible results. The previous method of
1831 reaping threads could return successfully while some Thread objects were

1860 test_heapq and test_warnings have been adjusted to use it, tests for
1861 other modules with both C and Python implementations in the stdlib

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001996- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001997 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001998 was correctly parsed but parsing of subsequent arguments failed.
1999
Vinay Sajip35e3b032008-09-01 14:33:59 +00002000- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002001 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2002 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2003 when given a tuple of classes as second argument, were looking up
2004 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2005 type object.
2006
Neal Norwitz18aa3882008-08-24 05:04:52 +00002007- Fix crashes on memory allocation failure found with failmalloc.

2076 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2077 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002144What's New in Python 2.6 beta 3?
2145================================
2146
Barry Warsaw07a4a382008-08-21 01:15:08 +00002147*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002148
2149Core and Builtins
2150-----------------
2151
Guido van Rossumf8402962008-08-20 15:01:50 +00002152- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2153 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2154 extensions do not automatically benefit from the class attribute
2155 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2156 to their tp_flags field if they care. This is a backwards
2157 compatibility feature; in 3.0, all types will use the cache by
2158 default.
2159
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002160- Keyword arguments can now follow starred arguments. (``f(a, *args,
2161 keyword=23)`` is now valid syntax.)
2162
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002163- ctypes function pointers that are COM methods have a boolean True
2164 value again.
2165
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002166- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2167 by denying s# to parse objects that have a releasebuffer procedure,
2168 and introducing s*.
2169
Georg Brandl1e13ea92008-08-11 09:07:59 +00002170- Issue #3537: Fix an assertion failure when an empty but presized dict
2171 object was stored in the freelist.
2172
Mark Dickinsonb6467572008-08-04 21:30:09 +00002173- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2174 ValueError consistently across platforms.
2175
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002176- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2177 (64bit Unix, for example), unichr() would truncate its argument and return
2178 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2179
Neal Norwitze7d8be82008-07-31 17:17:14 +00002180- Apply security patches from Apple.
2181
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002182- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2183 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2184
Antoine Pitrou92f82162008-07-25 22:22:08 +00002185- Issue #1819: function calls with several named parameters are now on
2186 average 35% faster (as measured by pybench).
2187
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002188- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2189 the python debugger steps into a class statement: the free variables (local
2190 variables defined in an outer scope) would be deleted from the outer scope.
2191
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002192- Issue #2620: Overflow checking when allocating or reallocating memory
2193 was not always being done properly in some python types and extension
2194 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2195 all been updated to perform better checks and places in the code that
2196 would previously leak memory on the error path when such an allocation
2197 failed have been fixed.

2201
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002202- Issue #3612: Added some missing basic types in ctypes.wintypes.
2203
Benjamin Petersone977ad42008-08-20 01:42:01 +00002204- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2205 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2206
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002207- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2208 version reported by these tools does not necessarily follow the python
2209 version numbering scheme, so the module is less strict when parsing it.
2210
Nick Coghlanf70385a2008-08-18 12:42:46 +00002211- Issue #2235: Added Py3k warnings for types which will become unhashable
2212 under the stricter __hash__ inheritance rules in 3.0. Several types
2213 which did not meet the rules for hash invariants and were already
2214 unhashable in 3.0 have now been explicitly flagged as unhashable in
2215 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2216 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2217
Brett Cannon88f801d2008-08-18 00:46:22 +00002218- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2219 imported into the module but exposed as part of the module's API.
2220
Brett Cannon7b96f072008-08-18 00:41:11 +00002221- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2222
Brett Cannon46225e72008-08-18 00:36:52 +00002223- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002225- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2226
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002227- Issue #3575: Incremental decoder's decode function now takes bytearray
2228 by using 's*' instead of 't#'.
2229
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002230- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002231 fails unicode conversion on 2nd parameter. (windows only)
2232
Facundo Batista94f243a2008-08-17 03:38:39 +00002233- Issue 2464. urllib2 now supports a malformation in the URL received
2234 in a redirect.
2235
Brett Cannonabe423e2008-08-16 21:47:07 +00002236- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002237 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002238
Facundo Batistaeb90b782008-08-16 14:44:07 +00002239- Issue #2776: fixed small issue when handling an URL with double slash
2240 after a 302 response in the case of not going through a proxy.
2241
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002242- Issue #2676: in the email package, content-type parsing was hanging on
2243 pathological input because of quadratic or exponential behaviour of a
2244 regular expression.
2245
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002246- Issue #3476: binary buffered reading through the new "io" library is now
2247 thread-safe.
2248
Brett Cannonbf3157b2008-08-14 05:00:03 +00002249- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2250 since mimetools itself is deprecated. Because modules are cached, all
2251 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2252
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002253- Issue #3134: shutil referenced undefined WindowsError symbol.
2254
Robert Schuppenies14646332008-08-10 11:01:53 +00002255- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2256 menu entries were not deleted.
2257
Brett Cannon83e81842008-08-09 23:30:55 +00002258- Copied the implementation of reduce() to _functools.reduce() to have a
2259 version that did not raise a DeprecationWarning under -3.
2260
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002261- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2262 a MemoryError rather than silently stop the iteration.
2263
Guido van Rossum59ce9012008-08-09 14:55:34 +00002264- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2265 to _sre.compile() will now be rejected. This should not affect anybody
2266 since the re.compile() function never generates invalid re-bytecode.
2267
Skip Montanaroa032bf42008-08-08 22:52:51 +00002268- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2269 upon first access it can be automatically initialized from the csv file if
2270 it wasn't initialized during instantiation.
2271
Brett Cannon3aa2a492008-08-06 22:28:09 +00002272- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2273 the reload() built-in has been removed.
2274
Brett Cannon7e30b672008-08-04 21:52:25 +00002275- Changed code in the following modules/packages to remove warnings raised

2344-----------------
2345
Georg Brandl3e483f62008-07-16 22:57:41 +00002346- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2347 its methods now allow for items objects that can be converted to
2348 an integer using operator.index().
2349
Mark Dickinson64b7e502008-07-16 09:40:03 +00002350- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2351 produced a ValueError instead of giving the correct float.
2352
Eric Smitha5fa5a22008-07-16 00:11:49 +00002353- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2354 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2355
Mark Dickinson7103aa42008-07-15 19:08:33 +00002356- Issue #3008: the float type has a new instance method 'float.hex'
2357 and a new class method 'float.fromhex' to convert floating-point
2358 numbers to and from hexadecimal strings, respectively.
2359
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002360- Issue #2235: __hash__ is once again inherited by default. To allow
2361 collections.Hashable to remain meaningful in the presence of the
2362 default hash implementation (object.__hash__), it is now possible
2363 to explicit block inheritance of hash by setting __hash__=None at
2364 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2365 level.
2366
Nick Coghlanb028f502008-07-13 14:52:36 +00002367- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2368 the parent module cannot be found while performing an absolute import.
2369 This means that an incorrectly defined __package__ attribute will
2370 now only prevent relative imports in that module rather than causing
2371 all imports from that module to fail.
2372
Nick Coghlan14ff9942008-07-08 14:21:42 +00002373- Issue #2517: Allow unicode messages in Exceptions again by correctly

2383 another thread's dictionary.
2384
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002385- Issue #3004: Minor change to slice.indices(): the start and stop
2386 arguments are now treated identically, making the behaviour easier
2387 to describe and understand. For example, slice(None, -10,
2388 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2389 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2390 10, -1).
2391
Georg Brandl278fc502008-07-19 12:46:12 +00002392- Issue #3219: Calling a function with repeated keyword arguments,
2393 f(a=2, a=23), would not cause a syntax error. This was a regression
2394 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002432- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2433 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002434 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002435 content-length. The problem had been corrected in the 2.4 branch, but never
2436 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002451- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2452 handling is now the same as that of other special attributes like __name__).
2453
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002454- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00002844 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002845
2846 This is controlled by the configure argument ``--with-universal-archs``:
2847
2848 - ``--with-universal-archs=all``: install 4-way universal
2849
2850 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2851
2852 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2853
2854 This option should be used in combination with ``--enable-universalsdk=``.
2855
2856 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2861
Georg Brandl74a1dea2008-05-28 11:21:39 +00002862- Add ``PyType_Modified()`` as a public API to clear the type cache.
2863
2864- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002865
2866- The PyString functions have been renamed to PyBytes. A batch of
2867 defines were added so that the linker still sees the original
2868 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002906- Issue #1631171: Re-implement the 'warnings' module in C (the
2907 original Python code has been kept as backup). This will allow for
2908 using the 'warning's machinery in such places as the parser where
2909 use of pure Python code is not possible. Both the ``showarning()``
2910 and ``formatwarning()`` gain an optional 'line' argument which is
2911 not called by default for backwards-compatibility reasons. Setting
2912 ``warnings.showwarning()`` to an implementation that lacks support
2913 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002955- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002956 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002976- Issue #2550: The approach used by client/server code for obtaining
2977 ports to listen on in network-oriented tests has been refined in an
2978 effort to facilitate running multiple instances of the entire
2979 regression test suite in parallel without issue.
2980 test_support.bind_port() has been fixed such that it will always
2981 return a unique port -- which wasn't always the case with the
2982 previous implementation, especially if socket options had been set
2983 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2984 new implementation of bind_port() will actually raise an exception
2985 if it is passed an AF_INET/SOCK_STREAM socket with either the
2986 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2987 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2988 the socket it's been passed. This currently only applies to
2989 Windows. This option prevents any other sockets from binding to the
2990 host/port we've bound to, thus removing the possibility of the
2991 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2992 when a second SOCK_STREAM socket binds and accepts to a host/port
2993 that's already been bound by another socket. The optional preferred
2994 port parameter to bind_port() has been removed. Under no
2995 circumstances should tests be hard coding ports!
2996
2997 test_support.find_unused_port() has also been introduced, which will
2998 pass a temporary socket object to bind_port() in order to obtain an
2999 unused port. The temporary socket object is then closed and
3000 deleted, and the port is returned. This method should only be used
3001 for obtaining an unused port in order to pass to an external program
3002 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3003 a parameter to a server-oriented class that doesn't give you direct
3004 access to the underlying socket used.
3005
3006 Finally, test_support.HOST has been introduced, which should be used
3007 for the host argument of any relevant socket calls (i.e. bind and
3008 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003009
3010 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003011 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003012 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3013 test_asynchat and test_socket_ssl.
3014
Georg Brandl3ee81df2008-05-17 18:14:43 +00003015 It is now possible for multiple instances of the regression test
3016 suite to run in parallel without issue.

3282Core and builtins
3283-----------------
3284
Fred Drakea8ee94b2008-03-01 02:45:07 +00003285- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003286 644. The mode is now inherited from the py file.

3289
3290- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003291
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003292- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003293 issue 215555 for a discussion.
3294
Eric Smitha73fbe72008-02-23 03:09:44 +00003295- Added the future_builtins module, which contains hex() and oct().
3296 These are the PEP 3127 version of these functions, designed to be
3297 compatible with the hex() and oct() builtins from Python 3.0. They
3298 differ slightly in their output formats from the existing, unchanged
3299 Python 2.6 builtins. The expected usage of the future_builtins
3300 module is:
3301 from future_builtins import hex, oct
3302
Eric Smith7ef40bf2008-02-20 23:34:22 +00003303- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3304 exponents for exponents with absolute value < 100. Follows C99
3305 standard. This is a change on Windows, which would use 3 digits.
3306 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3307 so that any alterations it does to the resulting string will be
3308 available in stringlib/formatter.h (for float.__format__).
3309
Eric Smith5a3c1352008-02-19 13:21:56 +00003310- Implemented PEP 3101, Advanced String Formatting. This adds a new
3311 builtin format(); a format() method for str and unicode; a
3312 __format__() method to object, str, unicode, int, long, float, and
3313 datetime; the class string.Formatter; and the C API
3314 PyObject_Format().
3315
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Fixed several potential crashes, all caused by specially crafted
3317 __del__ methods exploiting objects in temporarily inconsistent
3318 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003319
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003320- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003321 prevent a possible crash: an Abstract Base Class would try to access
3322 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003323

Georg Brandl3ee81df2008-05-17 18:14:43 +00003327- Clear all free lists during a gc.collect() of the highest generation
3328 in order to allow pymalloc to free more arenas. Python may give back
3329 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003330
Georg Brandl3ee81df2008-05-17 18:14:43 +00003331- Issue #2045: Fix an infinite recursion triggered when printing a
3332 subclass of collections.defaultdict, if its default_factory is set
3333 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003334
Christian Heimesf75dbef2008-02-08 00:11:31 +00003335- Fixed a minor memory leak in dictobject.c. The content of the free
3336 list was not freed on interpreter shutdown.
3337
Georg Brandl3ee81df2008-05-17 18:14:43 +00003338- Limit free list of method and builtin function objects to 256
3339 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003340
Georg Brandl3ee81df2008-05-17 18:14:43 +00003341- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3342 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003343 to compact the internal free lists of pre-allocted ints and floats.
3344
Georg Brandl3ee81df2008-05-17 18:14:43 +00003345- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3346 calls. Python expected the return type int but the fork familie
3347 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003348
Georg Brandl3ee81df2008-05-17 18:14:43 +00003349- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003365- Issue #1920: "while 0" statements were completely removed by the
3366 compiler, even in the presence of an "else" clause, which is
3367 supposed to be run when the condition is false. Now the compiler
3368 correctly emits bytecode for the "else" suite.

Guido van Rossumeead05f2008-01-24 18:21:02 +00003370- A few crashers fixed: weakref_in_del.py (issue #1377858);
3371 loosing_dict_ref.py (issue #1303614, test67.py);
3372 borrowed_ref_[34].py (not in tracker).
3373
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003374- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003375 suppressed while an extension is loaded by calling SetErrorMode in
3376 dynload_win.c. The error is still reported properly.
3377
Georg Brandl3ee81df2008-05-17 18:14:43 +00003378- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003379 several extension methods and modules do not work without unicode
3380 support.
3381
Georg Brandl26543b12008-01-21 18:36:51 +00003382- Issue #1882: when compiling code from a string, encoding cookies in the
3383 second line of code were not always recognized correctly.
3384
Georg Brandl14404b62008-01-19 19:27:05 +00003385- Issue #1679: "0x" was taken as a valid integer literal.
3386
Georg Brandl6caad7d2008-01-26 14:19:22 +00003387- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003388 added.
3389
Christian Heimesc94e2b52008-01-14 04:13:37 +00003390- sys.float_info / PyFloat_GetInfo: The floating point information
3391 object was converted from a dict to a specialized structseq object.
3392
Georg Brandl3ee81df2008-05-17 18:14:43 +00003393- Patch #1816: Added sys.flags structseq. It exposes the status of
3394 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003395
Georg Brandl3ee81df2008-05-17 18:14:43 +00003396- Objects/structseq.c: Implemented new structseq representation. The
3397 patch makes structseqs (e.g. the return value of os.stat) more
3398 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003399
Georg Brandl3ee81df2008-05-17 18:14:43 +00003400- Patch #1700288: added a type attribute cache that caches method
3401 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003402
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003403- Bug #1776: __import__() no longer accepts filenames on any platform.
3404 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003405
Georg Brandlaed6c662008-01-07 17:25:53 +00003406- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3407
Georg Brandl3ee81df2008-05-17 18:14:43 +00003408- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3409 envvar and sys.dont_write_bytecode attribute. All these can be set
3410 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003411
Georg Brandl3ee81df2008-05-17 18:14:43 +00003412- Improve some exception messages when Windows fails to load an
3413 extension module. Now we get for example '%1 is not a valid Win32
3414 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003415
Georg Brandl3ee81df2008-05-17 18:14:43 +00003416- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003418- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3419 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003420
Christian Heimes0a8143f2007-12-18 23:22:54 +00003421- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003422 and INF. float("nan"), float("inf") and float("-inf") now work on
3423 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003424
Georg Brandl3ee81df2008-05-17 18:14:43 +00003425- Compiler now generates simpler and faster code for dictionary
3426 literals. The oparg for BUILD_MAP now indicates an estimated
3427 dictionary size. There is a new opcode, STORE_MAP, for adding
3428 entries to the dictionary.

3446 running, and if the deallocation of its frames somehow calls the
3447 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003448

Georg Brandl3ee81df2008-05-17 18:14:43 +00003457- Patch #1739468: Directories and zipfiles containing a __main__.py
3458 file can now be directly executed by passing their name to the
3459 interpreter. The directory/zipfile is automatically inserted as the
3460 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003461
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Issue #1265: Fix a problem with sys.settrace, if the tracing
3463 function uses a generator expression when at the same time the
3464 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003465
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003466- sets and frozensets now have an isdisjoint() method.
3467
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003468- optimize the performance of builtin.sum().
3469
Neal Norwitz44f326e2007-10-05 05:29:17 +00003470- Fix warnings found by the new version of the Coverity checker.
3471
Georg Brandl3ee81df2008-05-17 18:14:43 +00003472- The enumerate() builtin function is no longer bounded to sequences
3473 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3474 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003475
Georg Brandl3ee81df2008-05-17 18:14:43 +00003476- Issue #1686386: Tuple's tp_repr did not take into account the
3477 possibility of having a self-referential tuple, which is possible
3478 from C code. Nor did object's tp_str consider that a type's tp_str
3479 could do something that could lead to an inifinite recursion.
3480 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3481 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003482
Georg Brandl3ee81df2008-05-17 18:14:43 +00003483- Issue #1164: It was possible to trigger deadlock when using the
3484 'print' statement to write to a file since the GIL was not released
3485 as needed. Now PyObject_Print() does the right thing along with
3486 various tp_print implementations of the built-in types and those in
3487 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003488
Georg Brandl3ee81df2008-05-17 18:14:43 +00003489- Issue #1147: Exceptions were directly allowing string exceptions in
3490 their throw() method even though string exceptions no longer
3491 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003492
Georg Brandl3ee81df2008-05-17 18:14:43 +00003493- Issue #1096: Prevent a segfault from getting the repr of a very
3494 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003495
Brett Cannon1e534b52007-09-07 04:18:30 +00003496- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497 PyObject_Call() never calling back out to Python code to trigger
3498 recursion depth updates/checks. Required the creation of a static
3499 RuntimeError instance in case normalizing an exception put the
3500 recursion check value past its limit. Fixes crashers
3501 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003502
Georg Brandl3ee81df2008-05-17 18:14:43 +00003503- Patch #1031213: Decode source line in SyntaxErrors back to its

3507 with %G.
3508
Georg Brandl3ee81df2008-05-17 18:14:43 +00003509- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00003516- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517 __*__ attributes. (Some already existed, e.g., __doc__ and
3518 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003519
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003520- Add -3 option to the interpreter to warn about features that are
3521 deprecated and will be changed/removed in Python 3.0.
3522
Georg Brandl2134e752007-05-21 20:34:16 +00003523- Patch #1686487: you can now pass any mapping after '**' in function
3524 calls.
3525
Collin Winter62903052007-05-18 23:11:24 +00003526- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003527 "except E as target:". This is to provide forwards compatibility
3528 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003529
Brett Cannon229cee22007-05-05 01:34:02 +00003530- Deprecate BaseException.message as per PEP 352.
3531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003533 inherited from a builtin base.
3534
Vinay Sajip8549ce32007-05-06 17:53:37 +00003535- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003536 setting a plain string, ie don't expand to single letter identifiers.
3537
Raymond Hettinger13936692007-04-11 18:40:58 +00003538- Request #1191699: Slices can now be pickled.
3539
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003540- Request #1193128: str.translate() now allows a None argument for
3541 translations that only remove characters without re-mapping the
3542 remaining characters.
3543
Georg Brandl5cb76c12007-03-21 09:00:39 +00003544- Patch #1682205: a TypeError while unpacking an iterable is no longer
3545 masked by a generic one with the message "unpack non-sequence".
3546
Neal Norwitzaa754b72007-03-21 06:39:48 +00003547- Remove unused file Python/fmod.c.
3548
Guido van Rossum143b5642007-03-23 04:58:42 +00003549- Bug #1683368: The object.__init__() and object.__new__() methods are
3550 now stricter in rejecting excess arguments. The only time when
3551 either allows excess arguments is when it is not overridden and the
3552 other one is. For backwards compatibility, when both are
3553 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003554 warning later). Also, type.__init__() insists on the same signature
3555 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003556
Georg Brandl3ee81df2008-05-17 18:14:43 +00003557- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3558 object to complex using its __complex__() method before falling back
3559 to the __float__() method. Therefore, the functions in the cmath
3560 module now can operate on objects that define a __complex__()
3561 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003562
Georg Brandl3ee81df2008-05-17 18:14:43 +00003563- Patch #1623563: allow __class__ assignment for classes with
3564 __slots__. The old and the new class are still required to have the
3565 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003566
Georg Brandl3ee81df2008-05-17 18:14:43 +00003567- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003570- Patch #1462488: Python no longer segfaults when
3571 ``object.__reduce_ex__()`` is called with an object that is faking
3572 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003577- Patch #1444529: the builtin compile() now accepts keyword arguments.
3578
Georg Brandl7b9c5552007-03-12 14:30:05 +00003579- Bug #1678647: write a newline after printing an exception in any
3580 case, even when converting the value to a string failed.
3581
Georg Brandl871f1bc2007-03-12 13:17:36 +00003582- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003583 its argument, if it exists. If not, it will work like before. This
3584 allows customizing the output of dir() in the presence of a
3585 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003586
Collin Winter276887b2007-03-12 16:11:39 +00003587- Patch #922167: Python no longer segfaults when faced with infinitely
3588 self-recursive reload() calls (as reported by bug #742342).
3589
Georg Brandl3ee81df2008-05-17 18:14:43 +00003590- Patch #1675981: remove unreachable code from ``type.__new__()``
3591 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003593- Patch #1491866: change the complex() constructor to allow
3594 parthensized forms. This means complex(repr(x)) now works instead of
3595 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003596
Georg Brandlaa2321b2007-03-07 00:40:28 +00003597- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003598 makes the filenames the warning module prints much more sensible
3599 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003600
Georg Brandl49aafc92007-03-07 00:34:46 +00003601- Variant of patch #697613: don't exit the interpreter on a SystemExit
3602 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003603 variable is given, but break into the interactive interpreter just

Facundo Batistad918a652007-04-24 13:54:38 +00004108- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109 the client's request was successfully received, understood, and

4121 work started with create_connection() and timeout in httplib, and
4122 closes patch #723312.
4123
Vinay Sajip8549ce32007-05-06 17:53:37 +00004124- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00004150 AttributeError instead of an IOError when the server's response
4151 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004152

Georg Brandl3ee81df2008-05-17 18:14:43 +00004157- Patch #1429539: pdb now correctly initializes the __main__ module
4158 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004159 correctly now.
4160

4167
Georg Brandl3ee81df2008-05-17 18:14:43 +00004168- Patch #1530482: add pydoc.render_doc() which returns the

4183
Georg Brandl92a6bae2007-03-13 17:43:32 +00004184- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004185 are set for invalid interpolation sequences that would lead to
4186 errors on reading back those values.

4240
Georg Brandl3ee81df2008-05-17 18:14:43 +00004241- unittest now verifies more of its assumptions. In particular,
4242 TestCase and TestSuite subclasses (not instances) are no longer
4243 accepted in TestSuite.addTest(). This should cause no
4244 incompatibility since it never made sense with ordinary subclasses
4245 -- the failure just occurred later, with a more cumbersome
4246 exception.

4255 given a unicode argument and os.listdir() returns unicode filenames.
4256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004257- Patch #1673619: setup.py identifies extension modules it doesn't
4258 know how to build and those it knows how to build but that fail to
4259 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004634- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004635 time so that opening a database previously created with the DB_DUP
4636 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4637 opens. Specifically: dictionary assignment to a DB object will
4638 replace all values for a given key when the database allows
4639 duplicate values. DB users should use DB.put(k, v) when they want
4640 to store duplicates; not DB[k] = v.

4647 characters with ASCII value less than 32. Also, it correctly quotes
4648 dots only if they occur on a single line, as opposed to the previous
4649 behavior of quoting dots if they are the second character of any
4650 line.
