79 processing: any non-float non-integer argument is now converted to

Mark Dickinson4f96f5f2010-05-04 14:25:50 +0000134- Issue #8567: Fix precedence of signals in Decimal module: when a
135 Decimal operation raises multiple signals and more than one of those
136 signals is trapped, the specification determines the order in which
137 the signals should be handled. In many cases this order wasn't
138 being followed, leading to the wrong Python exception being raised.

169 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
Nick Coghlan54677da2010-04-28 14:34:30 +0000170 location of the raised exception. Based on initial patch by Lennart
171 Regebro.

187 witnessed in test_httpservers.
188
Antoine Pitroufc69af12010-04-24 20:04:58 +0000189- Issue #5103: SSL handshake would ignore the socket timeout and block

Eric Smithd44b2fc2010-04-02 12:30:56 +0000326- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
327 is called with a non-empty format string. This is an effort to
328 future-proof user code. If a derived class does not currently
329 implement __format__ but later adds its own __format__, it would
330 most likely break user code that had supplied a format string. This
331 will be changed to a DeprecationWaring in Python 3.3 and it will be
332 an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +0000512- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
513 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
514 argument's __int__ method to convert to an integer before packing. It also
515 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
516 was inconsistent: __int__ was used for some integer codes but not for others,
517 and the set of integer codes for which it was used differed between native
518 packing and standard packing.)

825 ``io.BufferedReader`` object for more speedups. It also solves an issue
826 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

922
Mark Dickinson1b34d252010-01-01 17:27:30 +0000923- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000924 DeprecationWarning when passed a float argument where an integer was expected.
925 These functions and methods now raise TypeError instead. The majority of the
926 effects of this change are in the extension modules, but some core functions
927 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
928 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00001093- Issue #3382: 'F' formatting for float and complex now convert the result to
1094 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
1095 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001096
Georg Brandlba83f822010-03-14 09:50:54 +00001097- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1098 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001099
Georg Brandlba83f822010-03-14 09:50:54 +00001100- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
1101 1e-100 used to raise OverflowError, but now gives the requested 120
1102 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00001103
Georg Brandlba83f822010-03-14 09:50:54 +00001104- Add Py3k warnings for parameter names in parentheses.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001110
Georg Brandlba83f822010-03-14 09:50:54 +00001111- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1112 decimal string that's guaranteed to round back to x under correct rounding
1113 (with round-half-to-even rounding mode). Previously it gave a string based on
1114 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1115 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1116 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001117
Georg Brandlba83f822010-03-14 09:50:54 +00001118- Issue #7117: On almost all platforms: float-to-string and string-to-float
1119 conversions within Python are now correctly rounded. Places these conversions
1120 occur include: str for floats and complex numbers; the float and complex
1121 constructors; old-style and new-style numeric formatting; serialization and
1122 deserialization of floats and complex numbers using marshal, pickle and json;
1123 parsing of float and imaginary literals in Python code; Decimal-to-float
1124 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001125
Georg Brandlba83f822010-03-14 09:50:54 +00001126 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1127 providing correctly-rounded strtod and dtoa C functions. This code is
1128 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1129 the C compiler. There may be a small number of platforms on which correct
1130 operation of this code cannot be guaranteed, so the code is not used: notably,
1131 this applies to platforms where the C double format is not IEEE 754 binary64,
1132 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1133 and Python's configure script is unable to determine how to change the FPU
1134 precision. On these platforms conversions use the platform strtod and dtoa,
1135 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001136
Georg Brandlba83f822010-03-14 09:50:54 +00001137- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1138 uses the correctly-rounded string <-> float conversions described above (when
1139 available), and so produces correctly rounded results that will display nicely
1140 under the float repr. There are two related small changes: (1) round now
1141 accepts any class with an ``__index__()`` method for its second argument (but
1142 no longer accepts floats for the second argument), and (2) an excessively
1143 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1144 raises an exception.

1147
Georg Brandlba83f822010-03-14 09:50:54 +00001148- Fix several issues with ``compile()``. The input can now contain Windows and

Georg Brandlba83f822010-03-14 09:50:54 +00001291- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1292 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1293 but with at least one decimal point and with a default precision
1294 of 12. Previously, the behavior the same but with a default precision of 6.
1295 This more closely matches ``str()``, and reduces surprises when adding
1296 alignment flags to the empty presentation type. This also affects the new
1297 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001306- Issue #1588: Add complex.__format__. For example, ``format(complex(1, 2./3),
1307 '.5')`` now produces a sensible result.
Eric Smith9139cc62009-04-30 00:58:58 +00001308
Georg Brandlba83f822010-03-14 09:50:54 +00001309- Issue #5864: Fix empty format code formatting for floats so that it never
1310 gives more than the requested number of significant digits.
Mark Dickinson92fcc9c2009-04-29 20:41:00 +00001311
Georg Brandlba83f822010-03-14 09:50:54 +00001312- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes new

Eric Smith068f0652009-04-25 21:40:15 +00001318- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
1319 _PyOS_double_to_string or PyOS_double_to_string.
1320
Benjamin Peterson5083dc52009-04-25 00:41:22 +00001321- Issue #5283: Setting __class__ in __del__ caused a segfault.
1322
Georg Brandlba83f822010-03-14 09:50:54 +00001323- Issue #5816: ``complex(repr(z))`` now recovers z exactly, even when z involves
1324 nans, infs or negative zeros.

Georg Brandlba83f822010-03-14 09:50:54 +00001332- Issue #5772: For float.__format__, don't add a trailing ".0" if we're using no
1333 type code and we have an exponent.
Eric Smithaca19e62009-04-22 13:29:05 +00001334
Georg Brandlba83f822010-03-14 09:50:54 +00001335- Issue #3166: Make long -> float (and int -> float) conversions correctly

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001361- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001362 untrackable objects are not tracked by the garbage collector. This can reduce
1363 the size of collections and therefore the garbage collection overhead on
1364 long-running programs, depending on their particular use of datatypes.
Antoine Pitrouf8387af2009-03-23 18:41:45 +00001365
Georg Brandlba83f822010-03-14 09:50:54 +00001366- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to improve its

Georg Brandlba83f822010-03-14 09:50:54 +00001370- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
1371 internal representation of integers, for performance reasons. Base 2**30 is
1372 enabled by default on 64-bit machines. Add --enable-big-digits option to
1373 configure, which overrides the default. Add sys.long_info structseq to
1374 provide information about the internal format.
Mark Dickinsonefc82f72009-03-20 15:51:55 +00001375
Benjamin Peterson6ffe8522009-03-18 20:52:15 +00001376- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
1377 result traceback.__members__ no longer exists.)
1378
Georg Brandlba83f822010-03-14 09:50:54 +00001379- Issue #4474: PyUnicode_FromWideChar now converts characters outside the BMP to
1380 surrogate pairs, on systems with sizeof(wchar_t) == 4 and sizeof(Py_UNICODE)
1381 == 2.
Mark Dickinson6b265f12009-03-18 16:07:26 +00001382
Georg Brandlba83f822010-03-14 09:50:54 +00001383- Issue #5237: Allow auto-numbered fields in str.format(). For example: ``'{}
1384 {}'.format(1, 2) == '1 2'``.
Eric Smith6f42edb2009-03-14 11:57:26 +00001385
Georg Brandlba83f822010-03-14 09:50:54 +00001386- Issue #3652: Make the 'line' argument for ``warnings.showwarning()`` a
Brett Cannon6c4cff02009-03-11 04:51:06 +00001387 requirement. Means the DeprecationWarning from Python 2.6 can go away.
1388
Georg Brandlba83f822010-03-14 09:50:54 +00001389- Issue #5247: Improve error message when unknown format codes are used when
1390 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00001391
Georg Brandlba83f822010-03-14 09:50:54 +00001392- Running Python with the -3 option now also warns about classic division for
1393 ints and longs.
Raymond Hettinger08259e82009-02-18 23:10:19 +00001394
Georg Brandlba83f822010-03-14 09:50:54 +00001395- Issue #5260: Long integers now consume less memory: average saving is 2 bytes
1396 per long on a 32-bit system and 6 bytes per long on a 64-bit system.
Mark Dickinson2ffb26f2009-02-15 10:13:41 +00001397
Antoine Pitrou76a4b892009-02-13 13:52:33 +00001398- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1399 rotating the object pointer by 4 bits to the right.
1400
Georg Brandlba83f822010-03-14 09:50:54 +00001401- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs: it now
1402 forces its argument to double before testing for infinity.
Mark Dickinsonc97c9092009-02-09 14:18:43 +00001403
Benjamin Petersone18ef192009-01-20 14:21:16 +00001404- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
1405
Georg Brandl29c6a282009-04-05 20:23:13 +00001406- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00001407 were suppressing all exceptions. These include list(), filter(), map(),
1408 zip(), and bytearray().
1409
Benjamin Peterson596d3062009-01-19 15:42:23 +00001410- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
1411 functions.
1412
Benjamin Peterson5848d1f2009-01-19 00:08:08 +00001413- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
1414 OSError.
1415

1417
Georg Brandlba83f822010-03-14 09:50:54 +00001418- Issue #4935: The overflow checking code in the expandtabs() method common to
1419 str, bytes and bytearray could be optimized away by the compiler, letting the
1420 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +00001421
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +00001422- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1423 __next__ method.
1424

1428
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00001429- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1430 collecting the oldest generation) so that allocating lots of objects without
1431 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00001432 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +00001433 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

1436
Georg Brandlba83f822010-03-14 09:50:54 +00001437- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1438 existing .py counterpart, override the co_filename attributes of all code
1439 objects if the original filename is obsolete (which can happen if the file has
1440 been renamed, moved, or if it is accessed through different paths). Patch by
1441 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00001442
Georg Brandlba83f822010-03-14 09:50:54 +00001443- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.

1446 file with `str' filename on Windows.
1447
Antoine Pitrouaa687902009-01-01 14:11:22 +00001448- Issue #3680: Reference cycles created through a dict, set or deque iterator
1449 did not get collected.
1450
Georg Brandlba83f822010-03-14 09:50:54 +00001451- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
1452 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +00001453
Benjamin Peterson7af65562008-12-29 17:56:58 +00001454- Issue #4764: With io.open, IOError.filename is set when trying to open a
1455 directory on POSIX systems.
1456
Benjamin Petersonfe231b02008-12-29 17:47:42 +00001457- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1458 systems.
1459
Georg Brandl6425a2f2008-12-28 11:54:53 +00001460- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001461 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001462
Skip Montanarof205c132008-12-23 03:30:15 +00001463- Added test case to ensure attempts to read from a file opened for writing
1464 fail.
1465
Georg Brandlba83f822010-03-14 09:50:54 +00001466- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1467 elapsed times, not only when some objects are uncollectable/unreachable.
1468 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00001469

Georg Brandlba83f822010-03-14 09:50:54 +00001480- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1481 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1482 instances. On a typical machine this saves 3 bytes of memory (on average) per
1483 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001484
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001485- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1486 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1487 instead of throwing a MemoryError.
1488
Georg Brandlba83f822010-03-14 09:50:54 +00001489- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1490 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001491
Benjamin Petersonc078f922008-11-21 22:27:24 +00001492- Issue #4367: Python would segfault during compiling when the unicodedata
1493 module couldn't be imported and \N escapes were present.
1494
Georg Brandlba83f822010-03-14 09:50:54 +00001495- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1496 file objects with closefd=False. The file descriptor is still kept open but
1497 the file object behaves like a closed file. The ``FileIO`` object also got a
1498 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001499
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001500- Issue #4348: Some bytearray methods returned that didn't cause any change to
1501 the bytearray, returned the same bytearray instead of a copy.
1502
Georg Brandlba83f822010-03-14 09:50:54 +00001503- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

1506
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001507- Issue #4048: The parser module now correctly validates relative imports.
1508
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001509- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1516 __future__ import didn't work.
1517
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001518- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001519 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001520
Georg Brandlba83f822010-03-14 09:50:54 +00001521- On windows, ``os.chdir()`` given unicode was not working if
1522 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1523 this code path is really executed because I cannot move to such directory on
1524 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001525
Georg Brandlba83f822010-03-14 09:50:54 +00001526- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1527 element is temporarily replaced with an equivalent frozenset. But the
1528 eventual KeyError would always report the empty ``frozenset()`` as the missing
1529 key. Now it correctly refers to the initial element.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002925- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2926
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002927- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2928 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2929 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2930 ``printf`` function, whereas PyString_FromFormat has an independent
2931 implementation and uses "%zd" on all platforms for size_t values.
2932 This makes a difference on win64, where ``printf`` needs "%Id" to display
2933 64bit values.
2934
Benjamin Peterson97179b02008-09-09 20:55:01 +00002935- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2936 error.
2937
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002938- Issue #3777: long() applied to a float object now always return a long
2939 object; previously an int would be returned for small values. the __long__
2940 method is allowed to return either an int or a long, but the behaviour of
2941 float objects should not change to respect backward compatibility.
2942
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002943- Issue #3751: str.rpartition would perform a left-partition when called with
2944 a unicode argument.
2945
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002946- Issue #3683: Fix compilation when --without-threads is given.
2947
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002948- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002949 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002950 was correctly parsed but parsing of subsequent arguments failed.
2951
Vinay Sajip35e3b032008-09-01 14:33:59 +00002952- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002953 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2954 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2955 when given a tuple of classes as second argument, were looking up
2956 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2957 type object.
2958
Neal Norwitz18aa3882008-08-24 05:04:52 +00002959- Fix crashes on memory allocation failure found with failmalloc.
2960
2961- Fix memory leaks found with valgrind and update suppressions file.
2962
2963- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2964
2965- Fix problem using wrong name in decimal module reported by pychecker.
2966
Christian Heimes7d4c3172008-08-22 19:47:25 +00002967- Silenced another compiler warning about a used but not defined
2968 function 'stringlib_contains_obj'.
2969
Benjamin Peterson712ee922008-08-24 18:10:20 +00002970- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2971 ``__delslice__``.
2972
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002973- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2974 library targets in the Makefile.
2975
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002976- Issue #1204: The configure script now tests for additional libraries
2977 that may be required when linking against readline. This fixes issues
2978 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00002988- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
2989 stack usage in the case of deeply nested objects.
2990
Guido van Rossume3c4fd92008-09-10 14:27:00 +00002991- Issue #3629: Fix sre "bytecode" validator for an end case.

Nick Coghland2e09382008-09-11 12:11:06 +00002995- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
2996 silent misbehaviour when a single instance is nested in multiple
2997 with statements, or when the methods are invoked in the wrong order.
2998

Nick Coghland2e09382008-09-11 12:11:06 +00003001- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003002 return a list or None rather than a custom object.
3003
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003004- Issue #1638033: Cookie.Morsel gained the httponly attribute.

3028 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3029 for catch_warnings() also led to an improvement in the raising of a
3030 DeprecationWarning related to warnings.warn_explicit().
3031
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003032- The deprecation warnings for the old camelCase threading API were removed.

3057 without limit.
3058
Benjamin Peterson37346b22008-08-23 20:27:43 +00003059- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003096What's New in Python 2.6 beta 3?
3097================================
3098
Barry Warsaw07a4a382008-08-21 01:15:08 +00003099*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003100
3101Core and Builtins
3102-----------------
3103
Guido van Rossumf8402962008-08-20 15:01:50 +00003104- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3105 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3106 extensions do not automatically benefit from the class attribute
3107 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3108 to their tp_flags field if they care. This is a backwards
3109 compatibility feature; in 3.0, all types will use the cache by
3110 default.
3111
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003112- Keyword arguments can now follow starred arguments. (``f(a, *args,
3113 keyword=23)`` is now valid syntax.)
3114
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003115- ctypes function pointers that are COM methods have a boolean True
3116 value again.
3117
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003118- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3119 by denying s# to parse objects that have a releasebuffer procedure,
3120 and introducing s*.
3121
Georg Brandl1e13ea92008-08-11 09:07:59 +00003122- Issue #3537: Fix an assertion failure when an empty but presized dict
3123 object was stored in the freelist.
3124
Mark Dickinsonb6467572008-08-04 21:30:09 +00003125- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3126 ValueError consistently across platforms.
3127
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003128- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3129 (64bit Unix, for example), unichr() would truncate its argument and return
3130 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3131
Neal Norwitze7d8be82008-07-31 17:17:14 +00003132- Apply security patches from Apple.
3133
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003134- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3135 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3136
Antoine Pitrou92f82162008-07-25 22:22:08 +00003137- Issue #1819: function calls with several named parameters are now on
3138 average 35% faster (as measured by pybench).
3139
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003140- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3141 the python debugger steps into a class statement: the free variables (local
3142 variables defined in an outer scope) would be deleted from the outer scope.
3143
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003144- Issue #2620: Overflow checking when allocating or reallocating memory
3145 was not always being done properly in some python types and extension
3146 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3147 all been updated to perform better checks and places in the code that
3148 would previously leak memory on the error path when such an allocation
3149 failed have been fixed.

3153
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003154- Issue #3612: Added some missing basic types in ctypes.wintypes.
3155
Benjamin Petersone977ad42008-08-20 01:42:01 +00003156- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3157 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3158
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003159- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3160 version reported by these tools does not necessarily follow the python
3161 version numbering scheme, so the module is less strict when parsing it.
3162
Nick Coghlanf70385a2008-08-18 12:42:46 +00003163- Issue #2235: Added Py3k warnings for types which will become unhashable
3164 under the stricter __hash__ inheritance rules in 3.0. Several types
3165 which did not meet the rules for hash invariants and were already
3166 unhashable in 3.0 have now been explicitly flagged as unhashable in
3167 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3168 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3169
Brett Cannon88f801d2008-08-18 00:46:22 +00003170- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3171 imported into the module but exposed as part of the module's API.
3172
Brett Cannon7b96f072008-08-18 00:41:11 +00003173- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3174
Brett Cannon46225e72008-08-18 00:36:52 +00003175- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003177- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3178
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003179- Issue #3575: Incremental decoder's decode function now takes bytearray
3180 by using 's*' instead of 't#'.
3181
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003182- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003183 fails unicode conversion on 2nd parameter. (windows only)
3184
Facundo Batista94f243a2008-08-17 03:38:39 +00003185- Issue 2464. urllib2 now supports a malformation in the URL received
3186 in a redirect.
3187
Brett Cannonabe423e2008-08-16 21:47:07 +00003188- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003189 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003190
Facundo Batistaeb90b782008-08-16 14:44:07 +00003191- Issue #2776: fixed small issue when handling an URL with double slash
3192 after a 302 response in the case of not going through a proxy.
3193
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003194- Issue #2676: in the email package, content-type parsing was hanging on
3195 pathological input because of quadratic or exponential behaviour of a
3196 regular expression.
3197
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003198- Issue #3476: binary buffered reading through the new "io" library is now
3199 thread-safe.
3200
Brett Cannonbf3157b2008-08-14 05:00:03 +00003201- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3202 since mimetools itself is deprecated. Because modules are cached, all
3203 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3204
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003205- Issue #3134: shutil referenced undefined WindowsError symbol.
3206
Robert Schuppenies14646332008-08-10 11:01:53 +00003207- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3208 menu entries were not deleted.
3209
Brett Cannon83e81842008-08-09 23:30:55 +00003210- Copied the implementation of reduce() to _functools.reduce() to have a
3211 version that did not raise a DeprecationWarning under -3.
3212
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003213- Issue #3205: When iterating over a BZ2File fails allocating memory, raise

Guido van Rossum59ce9012008-08-09 14:55:34 +00003216- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3217 to _sre.compile() will now be rejected. This should not affect anybody
3218 since the re.compile() function never generates invalid re-bytecode.

Benjamin Peterson01a24322008-07-28 23:35:27 +00003238- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003239 asking for a specific length. This problem only affected files opened
3240 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003241

3267 mode 0600 rather than 000 under Unix.
3268
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003269- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3283
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003284- Issue #643841: The language reference now provides more detailed

3296-----------------
3297
Georg Brandl3e483f62008-07-16 22:57:41 +00003298- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3299 its methods now allow for items objects that can be converted to
3300 an integer using operator.index().
3301
Mark Dickinson64b7e502008-07-16 09:40:03 +00003302- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3303 produced a ValueError instead of giving the correct float.
3304
Eric Smitha5fa5a22008-07-16 00:11:49 +00003305- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3306 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3307
Mark Dickinson7103aa42008-07-15 19:08:33 +00003308- Issue #3008: the float type has a new instance method 'float.hex'
3309 and a new class method 'float.fromhex' to convert floating-point
3310 numbers to and from hexadecimal strings, respectively.
3311
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003312- Issue #2235: __hash__ is once again inherited by default. To allow
3313 collections.Hashable to remain meaningful in the presence of the
3314 default hash implementation (object.__hash__), it is now possible
3315 to explicit block inheritance of hash by setting __hash__=None at
3316 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3317 level.
3318
Nick Coghlanb028f502008-07-13 14:52:36 +00003319- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3320 the parent module cannot be found while performing an absolute import.
3321 This means that an incorrectly defined __package__ attribute will
3322 now only prevent relative imports in that module rather than causing
3323 all imports from that module to fail.
3324
Nick Coghlan14ff9942008-07-08 14:21:42 +00003325- Issue #2517: Allow unicode messages in Exceptions again by correctly

3335 another thread's dictionary.
3336
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003337- Issue #3004: Minor change to slice.indices(): the start and stop
3338 arguments are now treated identically, making the behaviour easier
3339 to describe and understand. For example, slice(None, -10,
3340 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3341 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3342 10, -1).
3343
Georg Brandl278fc502008-07-19 12:46:12 +00003344- Issue #3219: Calling a function with repeated keyword arguments,
3345 f(a=2, a=23), would not cause a syntax error. This was a regression
3346 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003347
Georg Brandl278fc502008-07-19 12:46:12 +00003348- Issue #2862: Make int and float freelist management consistent with
3349 other freelists. Changes their CompactFreeList apis into

3356 api functions without holding the GIL, which could lead to a fatal
3357 error when they failed.
3358
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003359- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003384- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3385 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003386 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003387 content-length. The problem had been corrected in the 2.4 branch, but never
3388 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003403- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

3405
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003406- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3791
Brett Cannonb61d8012008-05-11 23:39:04 +00003792- ``Lib/lib-old`` is now added to sys.path.
3793
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003794- On MacOS X it is now possible to install the framework in 64-bit
3795 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003796 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003797
3798 This is controlled by the configure argument ``--with-universal-archs``:
3799
3800 - ``--with-universal-archs=all``: install 4-way universal
3801
3802 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3803
3804 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3805
3806 This option should be used in combination with ``--enable-universalsdk=``.
3807
3808 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 +00003817
3818- The PyString functions have been renamed to PyBytes. A batch of
3819 defines were added so that the linker still sees the original
3820 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- Issue #1631171: Re-implement the 'warnings' module in C (the
3859 original Python code has been kept as backup). This will allow for
3860 using the 'warning's machinery in such places as the parser where
3861 use of pure Python code is not possible. Both the ``showarning()``
3862 and ``formatwarning()`` gain an optional 'line' argument which is
3863 not called by default for backwards-compatibility reasons. Setting
3864 ``warnings.showwarning()`` to an implementation that lacks support
3865 for the ``line`` argument will raise a DeprecationWarning.

3889
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003890- The getpass module has been improved on Unix. It now uses /dev/tty
3891 by default and uses stderr instead of stdout. A GetPassWarning is
3892 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003907- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003908 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003928- Issue #2550: The approach used by client/server code for obtaining
3929 ports to listen on in network-oriented tests has been refined in an
3930 effort to facilitate running multiple instances of the entire
3931 regression test suite in parallel without issue.
3932 test_support.bind_port() has been fixed such that it will always
3933 return a unique port -- which wasn't always the case with the
3934 previous implementation, especially if socket options had been set
3935 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3936 new implementation of bind_port() will actually raise an exception
3937 if it is passed an AF_INET/SOCK_STREAM socket with either the
3938 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3939 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3940 the socket it's been passed. This currently only applies to
3941 Windows. This option prevents any other sockets from binding to the
3942 host/port we've bound to, thus removing the possibility of the
3943 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3944 when a second SOCK_STREAM socket binds and accepts to a host/port
3945 that's already been bound by another socket. The optional preferred
3946 port parameter to bind_port() has been removed. Under no
3947 circumstances should tests be hard coding ports!
3948
3949 test_support.find_unused_port() has also been introduced, which will
3950 pass a temporary socket object to bind_port() in order to obtain an
3951 unused port. The temporary socket object is then closed and
3952 deleted, and the port is returned. This method should only be used
3953 for obtaining an unused port in order to pass to an external program
3954 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3955 a parameter to a server-oriented class that doesn't give you direct
3956 access to the underlying socket used.
3957
3958 Finally, test_support.HOST has been introduced, which should be used
3959 for the host argument of any relevant socket calls (i.e. bind and
3960 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003961
3962 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003963 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003964 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3965 test_asynchat and test_socket_ssl.
3966
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967 It is now possible for multiple instances of the regression test
3968 suite to run in parallel without issue.

4235-----------------
4236
Fred Drakea8ee94b2008-03-01 02:45:07 +00004237- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004238 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004239
Georg Brandlad61bc82008-02-23 15:11:18 +00004240- Issue #2067: file.__exit__() now calls subclasses' close() method.
4241
4242- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004243
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004244- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004245 issue 215555 for a discussion.
4246
Eric Smitha73fbe72008-02-23 03:09:44 +00004247- Added the future_builtins module, which contains hex() and oct().
4248 These are the PEP 3127 version of these functions, designed to be
4249 compatible with the hex() and oct() builtins from Python 3.0. They
4250 differ slightly in their output formats from the existing, unchanged
4251 Python 2.6 builtins. The expected usage of the future_builtins
4252 module is:
4253 from future_builtins import hex, oct
4254
Eric Smith7ef40bf2008-02-20 23:34:22 +00004255- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4256 exponents for exponents with absolute value < 100. Follows C99
4257 standard. This is a change on Windows, which would use 3 digits.
4258 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4259 so that any alterations it does to the resulting string will be
4260 available in stringlib/formatter.h (for float.__format__).
4261
Eric Smith5a3c1352008-02-19 13:21:56 +00004262- Implemented PEP 3101, Advanced String Formatting. This adds a new
4263 builtin format(); a format() method for str and unicode; a
4264 __format__() method to object, str, unicode, int, long, float, and
4265 datetime; the class string.Formatter; and the C API
4266 PyObject_Format().
4267
Georg Brandl3ee81df2008-05-17 18:14:43 +00004268- Fixed several potential crashes, all caused by specially crafted
4269 __del__ methods exploiting objects in temporarily inconsistent
4270 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004271
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004272- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004273 prevent a possible crash: an Abstract Base Class would try to access
4274 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004275

Georg Brandl3ee81df2008-05-17 18:14:43 +00004279- Clear all free lists during a gc.collect() of the highest generation
4280 in order to allow pymalloc to free more arenas. Python may give back
4281 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004282
Georg Brandl3ee81df2008-05-17 18:14:43 +00004283- Issue #2045: Fix an infinite recursion triggered when printing a
4284 subclass of collections.defaultdict, if its default_factory is set
4285 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004286
Christian Heimesf75dbef2008-02-08 00:11:31 +00004287- Fixed a minor memory leak in dictobject.c. The content of the free
4288 list was not freed on interpreter shutdown.
4289
Georg Brandl21e99f42010-03-07 15:23:59 +00004290- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004291 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004292
Georg Brandl3ee81df2008-05-17 18:14:43 +00004293- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4294 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004295 to compact the internal free lists of pre-allocted ints and floats.
4296
Georg Brandl3ee81df2008-05-17 18:14:43 +00004297- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4298 calls. Python expected the return type int but the fork familie
4299 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004300
Georg Brandl3ee81df2008-05-17 18:14:43 +00004301- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4302 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004303
Georg Brandl3ee81df2008-05-17 18:14:43 +00004304- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4305 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004306
Georg Brandl3ee81df2008-05-17 18:14:43 +00004307- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4308 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004309
Georg Brandl3ee81df2008-05-17 18:14:43 +00004310- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4311 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004312
Georg Brandl3ee81df2008-05-17 18:14:43 +00004313- Patch #1473257: generator objects gain a gi_code attribute. This is
4314 the same object as the func_code attribute of the function that
4315 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004316
Georg Brandl3ee81df2008-05-17 18:14:43 +00004317- Issue #1920: "while 0" statements were completely removed by the
4318 compiler, even in the presence of an "else" clause, which is
4319 supposed to be run when the condition is false. Now the compiler
4320 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004321
Guido van Rossumeead05f2008-01-24 18:21:02 +00004322- A few crashers fixed: weakref_in_del.py (issue #1377858);
4323 loosing_dict_ref.py (issue #1303614, test67.py);
4324 borrowed_ref_[34].py (not in tracker).
4325
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004326- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004327 suppressed while an extension is loaded by calling SetErrorMode in
4328 dynload_win.c. The error is still reported properly.
4329
Georg Brandl3ee81df2008-05-17 18:14:43 +00004330- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004331 several extension methods and modules do not work without unicode
4332 support.
4333
Georg Brandl26543b12008-01-21 18:36:51 +00004334- Issue #1882: when compiling code from a string, encoding cookies in the
4335 second line of code were not always recognized correctly.
4336
Georg Brandl14404b62008-01-19 19:27:05 +00004337- Issue #1679: "0x" was taken as a valid integer literal.
4338
Georg Brandl6caad7d2008-01-26 14:19:22 +00004339- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004340 added.
4341
Christian Heimesc94e2b52008-01-14 04:13:37 +00004342- sys.float_info / PyFloat_GetInfo: The floating point information
4343 object was converted from a dict to a specialized structseq object.
4344
Georg Brandl3ee81df2008-05-17 18:14:43 +00004345- Patch #1816: Added sys.flags structseq. It exposes the status of
4346 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004347
Georg Brandl3ee81df2008-05-17 18:14:43 +00004348- Objects/structseq.c: Implemented new structseq representation. The
4349 patch makes structseqs (e.g. the return value of os.stat) more
4350 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004351
Georg Brandl3ee81df2008-05-17 18:14:43 +00004352- Patch #1700288: added a type attribute cache that caches method
4353 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004354
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004355- Bug #1776: __import__() no longer accepts filenames on any platform.
4356 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004357
Georg Brandlaed6c662008-01-07 17:25:53 +00004358- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4359
Georg Brandl3ee81df2008-05-17 18:14:43 +00004360- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4361 envvar and sys.dont_write_bytecode attribute. All these can be set
4362 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004363
Georg Brandl3ee81df2008-05-17 18:14:43 +00004364- Improve some exception messages when Windows fails to load an
4365 extension module. Now we get for example '%1 is not a valid Win32
4366 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004367

Christian Heimes0a8143f2007-12-18 23:22:54 +00004373- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004374 and INF. float("nan"), float("inf") and float("-inf") now work on
4375 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004376
Georg Brandl3ee81df2008-05-17 18:14:43 +00004377- Compiler now generates simpler and faster code for dictionary
4378 literals. The oparg for BUILD_MAP now indicates an estimated
4379 dictionary size. There is a new opcode, STORE_MAP, for adding
4380 entries to the dictionary.

4392
Nick Coghlanef01d822007-12-03 12:55:17 +00004393- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004409- Patch #1739468: Directories and zipfiles containing a __main__.py
4410 file can now be directly executed by passing their name to the
4411 interpreter. The directory/zipfile is automatically inserted as the
4412 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004413
Georg Brandl3ee81df2008-05-17 18:14:43 +00004414- Issue #1265: Fix a problem with sys.settrace, if the tracing
4415 function uses a generator expression when at the same time the
4416 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004417
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004418- sets and frozensets now have an isdisjoint() method.
4419
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004420- optimize the performance of builtin.sum().
4421
Neal Norwitz44f326e2007-10-05 05:29:17 +00004422- Fix warnings found by the new version of the Coverity checker.
4423
Georg Brandl21e99f42010-03-07 15:23:59 +00004424- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004425 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4426 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004427
Georg Brandl3ee81df2008-05-17 18:14:43 +00004428- Issue #1686386: Tuple's tp_repr did not take into account the
4429 possibility of having a self-referential tuple, which is possible
4430 from C code. Nor did object's tp_str consider that a type's tp_str
4431 could do something that could lead to an inifinite recursion.
4432 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4433 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004434
Georg Brandl3ee81df2008-05-17 18:14:43 +00004435- Issue #1164: It was possible to trigger deadlock when using the
4436 'print' statement to write to a file since the GIL was not released
4437 as needed. Now PyObject_Print() does the right thing along with
4438 various tp_print implementations of the built-in types and those in
4439 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004440
Georg Brandl3ee81df2008-05-17 18:14:43 +00004441- Issue #1147: Exceptions were directly allowing string exceptions in
4442 their throw() method even though string exceptions no longer
4443 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004444
Georg Brandl3ee81df2008-05-17 18:14:43 +00004445- Issue #1096: Prevent a segfault from getting the repr of a very
4446 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004447
Brett Cannon1e534b52007-09-07 04:18:30 +00004448- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004449 PyObject_Call() never calling back out to Python code to trigger
4450 recursion depth updates/checks. Required the creation of a static
4451 RuntimeError instance in case normalizing an exception put the
4452 recursion check value past its limit. Fixes crashers
4453 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004454
Georg Brandl3ee81df2008-05-17 18:14:43 +00004455- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004468- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004469 __*__ attributes. (Some already existed, e.g., __doc__ and
4470 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004471
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004472- Add -3 option to the interpreter to warn about features that are
4473 deprecated and will be changed/removed in Python 3.0.
4474
Georg Brandl2134e752007-05-21 20:34:16 +00004475- Patch #1686487: you can now pass any mapping after '**' in function
4476 calls.
4477
Collin Winter62903052007-05-18 23:11:24 +00004478- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004479 "except E as target:". This is to provide forwards compatibility
4480 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004481
Brett Cannon229cee22007-05-05 01:34:02 +00004482- Deprecate BaseException.message as per PEP 352.
4483
Georg Brandl3ee81df2008-05-17 18:14:43 +00004484- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004485 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004486
Vinay Sajip8549ce32007-05-06 17:53:37 +00004487- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004488 setting a plain string, ie don't expand to single letter identifiers.
4489
Raymond Hettinger13936692007-04-11 18:40:58 +00004490- Request #1191699: Slices can now be pickled.
4491
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004492- Request #1193128: str.translate() now allows a None argument for
4493 translations that only remove characters without re-mapping the
4494 remaining characters.
4495
Georg Brandl5cb76c12007-03-21 09:00:39 +00004496- Patch #1682205: a TypeError while unpacking an iterable is no longer
4497 masked by a generic one with the message "unpack non-sequence".
4498
Neal Norwitzaa754b72007-03-21 06:39:48 +00004499- Remove unused file Python/fmod.c.
4500
Guido van Rossum143b5642007-03-23 04:58:42 +00004501- Bug #1683368: The object.__init__() and object.__new__() methods are
4502 now stricter in rejecting excess arguments. The only time when
4503 either allows excess arguments is when it is not overridden and the
4504 other one is. For backwards compatibility, when both are
4505 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004506 warning later). Also, type.__init__() insists on the same signature
4507 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004508
Georg Brandl3ee81df2008-05-17 18:14:43 +00004509- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4510 object to complex using its __complex__() method before falling back
4511 to the __float__() method. Therefore, the functions in the cmath
4512 module now can operate on objects that define a __complex__()
4513 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004514
Georg Brandl3ee81df2008-05-17 18:14:43 +00004515- Patch #1623563: allow __class__ assignment for classes with
4516 __slots__. The old and the new class are still required to have the
4517 same slot names.

4523 ``object.__reduce_ex__()`` is called with an object that is faking
4524 its type.

4530
Georg Brandl7b9c5552007-03-12 14:30:05 +00004531- Bug #1678647: write a newline after printing an exception in any
4532 case, even when converting the value to a string failed.
4533
Georg Brandl871f1bc2007-03-12 13:17:36 +00004534- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004535 its argument, if it exists. If not, it will work like before. This
4536 allows customizing the output of dir() in the presence of a
4537 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005061 the client's request was successfully received, understood, and

5075
Vinay Sajip8549ce32007-05-06 17:53:37 +00005076- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00005102 AttributeError instead of an IOError when the server's response
5103 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005137 are set for invalid interpolation sequences that would lead to
5138 errors on reading back those values.

5194 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00005587 time so that opening a database previously created with the DB_DUP
5588 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5589 opens. Specifically: dictionary assignment to a DB object will
5590 replace all values for a given key when the database allows
5591 duplicate values. DB users should use DB.put(k, v) when they want
5592 to store duplicates; not DB[k] = v.

5599 characters with ASCII value less than 32. Also, it correctly quotes
5600 dots only if they occur on a single line, as opposed to the previous
5601 behavior of quoting dots if they are the second character of any
5602 line.
