Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000029- Issue #7419: setlocale() could crash the interpreter on Windows when called
30 with invalid values.
31
Eric Smithc4ab8332009-11-29 17:40:57 +000032- Issue #3382: 'F' formatting for float and complex now convert the
33 result to upper case. This only affects 'inf' and 'nan', since 'f'
34 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000035
Mark Dickinson9dd5e162009-11-23 20:54:09 +000036- Remove switch from "%f" formatting to "%g" formatting for floats
37 larger than 1e50 in absolute value.
38
Mark Dickinson18cfada2009-11-23 18:46:41 +000039- Remove restrictions on precision when formatting floats. E.g.,
40 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
41 requested 120 significant digits instead.
42
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000043- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +000047- Issue #7085: Fix crash when importing some extensions in a thread
48 on MacOSX 10.6.
49
Mark Dickinsonb678de82009-11-19 18:41:49 +000050- Issue #7117: repr(x) for a float x returns a result based on the
51 shortest decimal string that's guaranteed to round back to x under
52 correct rounding (with round-half-to-even rounding mode).
53 Previously it gave a string based on rounding x to 17 decimal digits.
54 repr(x) for a complex number behaves similarly. On platforms where
55 the correctly-rounded strtod and dtoa code is not supported (see below),
56 repr is unchanged.
57
58- Issue #7117: On almost all platforms: float-to-string and
59 string-to-float conversions within Python are now correctly rounded.
60 Places these conversions occur include: str for floats and complex
61 numbers; the float and complex constructors; old-style and new-style
62 numeric formatting; serialization and deserialization of floats and
63 complex numbers using marshal, pickle and json; parsing of float and
64 imaginary literals in Python code; Decimal-to-float conversion.
65
66 The conversions use a Python-adapted version of David Gay's
67 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
68 functions. This code is supported on Windows, and on Unix-like
69 platforms using gcc, icc or suncc as the C compiler. There may be a
70 small number of platforms on which correct operation of this code
71 cannot be guaranteed, so the code is not used: notably, this applies
72 to platforms where the C double format is not IEEE 754 binary64, and
73 to platforms on x86 hardware where the x87 FPU is set to 64-bit
74 precision and Python's configure script is unable to determine how
75 to change the FPU precision. On these platforms conversions use the
76 platform strtod and dtoa, as before.
77
Mark Dickinsonbd15a062009-11-18 19:33:35 +000078- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000079 now uses the correctly-rounded string <-> float conversions
80 described above (when available), and so produces correctly rounded
81 results that will display nicely under the float repr. There are
82 two related small changes: (1) round now accepts any class with an
83 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000084 floats for the second argument), and (2) an excessively large second
85 integer argument (e.g., round(1.234, 10**100)) no longer raises an
86 exception.
87
Philip Jenveyfab8be22009-11-17 02:42:26 +000088- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000228- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
229 (1) inf and nan strings with trailing whitespace were incorrectly
230 rejected; (2) parsing of strings representing infinities and nans
231 was locale aware; and (3) the interpretation of fromhex('-nan')
232 didn't match that of float('-nan').
233
Eric Smitha985a3a2009-05-05 18:26:08 +0000234- Issue #5920: For float.__format__, change the behavior with the
235 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
236 to be like 'g' but with at least one decimal point and with a
237 default precision of 12. Previously, the behavior the same but with
238 a default precision of 6. This more closely matches str(), and
239 reduces surprises when adding alignment flags to the empty
240 presentation type. This also affects the new complex.__format__ in
241 the same way.
242
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000243- Issue #5890: in subclasses of 'property' the __doc__ attribute was

306 untrackable objects are not tracked by the garbage collector. This can
307 reduce the size of collections and therefore the garbage collection overhead
308 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson0b666bf2009-03-23 18:25:13 +0000310- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
311 improve its performance. Long divisions and remainder operations
312 are now between 50% and 150% faster.
313
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000314- Issue #4258: Make it possible to use base 2**30 instead of base
315 2**15 for the internal representation of integers, for performance
316 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
317 --enable-big-digits option to configure, which overrides the
318 default. Add sys.long_info structseq to provide information about
319 the internal format.

Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000321- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
322 result traceback.__members__ no longer exists.)
323
Mark Dickinson6b265f12009-03-18 16:07:26 +0000324- Issue #4474: PyUnicode_FromWideChar now converts characters outside
325 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
326 and sizeof(Py_UNICODE) == 2.
327
Eric Smith6f42edb2009-03-14 11:57:26 +0000328- Issue #5237: Allow auto-numbered fields in str.format(). For
329 example: '{} {}'.format(1, 2) == '1 2'.
330
Brett Cannon6c4cff02009-03-11 04:51:06 +0000331- Issue #3652: Make the 'line' argument for warnings.showwarning() a
332 requirement. Means the DeprecationWarning from Python 2.6 can go away.
333
Eric Smithe9fb6862009-02-20 14:02:36 +0000334- Issue #5247: Improve error message when unknown format codes are
335 used when using str.format() with str, unicode, long, int, and
336 float arguments.
337
Raymond Hettinger08259e82009-02-18 23:10:19 +0000338- Running Python with the -3 option now also warns about classic division
339 for ints and longs.
340
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000341- Issue #5260: Long integers now consume less memory: average
342 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
343 on a 64-bit system.
344
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000345- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
346 rotating the object pointer by 4 bits to the right.
347
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000348- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
349 it now forces its argument to double before testing for infinity.
350
Benjamin Petersone18ef192009-01-20 14:21:16 +0000351- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
352
Georg Brandl29c6a282009-04-05 20:23:13 +0000353- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000354 were suppressing all exceptions. These include list(), filter(), map(),
355 zip(), and bytearray().
356
Benjamin Peterson596d3062009-01-19 15:42:23 +0000357- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
358 functions.
359
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000360- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
361 OSError.
362
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +0000363- Issue #4807: Port the _winreg module to Windows CE.
364
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000365- Issue #4935: The overflow checking code in the expandtabs() method common
366 to str, bytes and bytearray could be optimized away by the compiler, letting
367 the interpreter segfault instead of raising an error.
368
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000369- Issue #3720: Fix a crash when an iterator modifies its class and removes its
370 __next__ method.

375
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000376- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
377 collecting the oldest generation) so that allocating lots of objects without
378 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000379 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000380 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

383
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000384- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
385 an existing .py counterpart, override the co_filename attributes of all
386 code objects if the original filename is obsolete (which can happen if the
387 file has been renamed, moved, or if it is accessed through different paths).
388 Patch by Ziga Seilnacht and Jean-Paul Calderone.
389
Martin v. Löwis5344c992009-01-02 20:32:55 +0000390- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000392- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
393 file with `str' filename on Windows.
394
Antoine Pitrouaa687902009-01-01 14:11:22 +0000395- Issue #3680: Reference cycles created through a dict, set or deque iterator
396 did not get collected.
397
Nick Coghlan180e4002008-12-30 01:18:48 +0000398- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
399 where the tp_hash and tp_dict slots are both NULL.
400
Benjamin Peterson7af65562008-12-29 17:56:58 +0000401- Issue #4764: With io.open, IOError.filename is set when trying to open a
402 directory on POSIX systems.
403
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000404- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
405 systems.
406
Georg Brandl6425a2f2008-12-28 11:54:53 +0000407- Issue #4759: None is now allowed as the first argument of
408 bytearray.translate(). It was always allowed for bytes.translate().
409
Skip Montanarof205c132008-12-23 03:30:15 +0000410- Added test case to ensure attempts to read from a file opened for writing
411 fail.
412
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000413- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
414 print elapsed times, not only when some objects are uncollectable /
415 unreachable. Original patch by Neil Schemenauer.
416
Mark Dickinson1a707982008-12-17 16:14:37 +0000417- Issue #3439: Add a bit_length method to int and long.

420 Original patch by Neal Norwitz.
421
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000422- Issue #4597: Fixed exception handling when the __exit__ function of a
423 context manager returns a value that cannot be converted to a bool.
424
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000425- Issue #4597: Fixed several opcodes that weren't always propagating
426 exceptions.
427
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000428- Issue #4445: Replace "sizeof(PyStringObject)" with
429 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
430 str instances. On a typical machine this saves 3 bytes of memory
431 (on average) per string allocation.
432
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000433- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
434 interpreter to abort ("Fatal Python error: Could not reset the stack!")
435 instead of throwing a MemoryError.
436
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000437- Issue #3689: The list reversed iterator now supports __length_hint__
438 instead of __len__. Behavior now matches other reversed iterators.
439
Benjamin Petersonc078f922008-11-21 22:27:24 +0000440- Issue #4367: Python would segfault during compiling when the unicodedata
441 module couldn't be imported and \N escapes were present.
442
Vinay Sajip213faca2008-12-03 23:22:58 +0000443- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000444 method on file objects with closefd=False. The file descriptor is still
445 kept open but the file object behaves like a closed file. The ``FileIO``
446 object also got a new readonly attribute ``closefd``.
447
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000448- Issue #4348: Some bytearray methods returned that didn't cause any change to
449 the bytearray, returned the same bytearray instead of a copy.
450
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000451- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
452
Benjamin Peterson273c2332008-11-17 22:39:09 +0000453- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
454
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000455- Issue #4048: The parser module now correctly validates relative imports.
456
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000457- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
458 exec statement.
459
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000460- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
461 method does not return iterators for the 4th and 5th items.
462
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000463- Issue #4209: Enabling unicode_literals and the print_function in the same
464 __future__ import didn't work.
465
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000466- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000467 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000468
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000469- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
470 returned a path longer than MAX_PATH. (But It's doubtful this code path is
471 really executed because I cannot move to such directory on win2k)
472
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000473- Issue #4069: When set.remove(element) is used with a set element, the element
474 is temporarily replaced with an equivalent frozenset. But the eventual
475 KeyError would always report the empty frozenset([]) as the missing key. Now
476 it correctly refers to the initial element.
477
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000478- Issue #4509: Various issues surrounding resize of bytearray objects to
479 which there are buffer exports.

Gregory P. Smithae91d092009-03-02 05:13:57 +0000485- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
486
Matthias Kloseedb5e1e2009-04-04 14:18:13 +0000487- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
488 short file names.
489
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000490- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
491 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000492
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000493- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
494 returned them on 64bit platforms.
495
Walter Dörwalded960ac2009-05-03 22:36:33 +0000496- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
497 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
498 step. This avoids problems with counting UTF-8 bytes that ignores the effect
499 of using the replace error handler in PyUnicode_DecodeUTF8().
500
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000501- Issue #3739: The unicode-internal encoder now reports the number of characters
502 consumed like any other encoder (instead of the number of bytes).
503
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000504- Issue #2422: When compiled with the ``--with-valgrind`` option, the
505 pymalloc allocator will be automatically disabled when running under
506 Valgrind. This gives improved memory leak detection when running
507 under Valgrind, while taking advantage of pymalloc at other times.

568
Nick Coghlan49868cb2009-11-15 07:30:34 +0000569- Issue #6816: runpy now provides a run_path function that allows Python code
570 to execute file paths that refer to source or compiled Python files as well
571 as zipfiles, directories and other valid sys.path entries that contain a
572 __main__.py file. This allows applications that run other Python scripts to

1734 leak-chasing test runs give sensible results. The previous method of
1735 reaping threads could return successfully while some Thread objects were

1755 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

1763 it easy to import both normal and optimised versions of modules.
1764 test_heapq and test_warnings have been adjusted to use it, tests for
1765 other modules with both C and Python implementations in the stdlib
1766 can be adjusted to use it over time.

1878
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001879- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1880 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1881 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1882 ``printf`` function, whereas PyString_FromFormat has an independent
1883 implementation and uses "%zd" on all platforms for size_t values.
1884 This makes a difference on win64, where ``printf`` needs "%Id" to display
1885 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001887- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1891 object; previously an int would be returned for small values. the __long__

Vinay Sajip35e3b032008-09-01 14:33:59 +00001901 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001902 was correctly parsed but parsing of subsequent arguments failed.
1903
Vinay Sajip35e3b032008-09-01 14:33:59 +00001904- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001905 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1906 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1907 when given a tuple of classes as second argument, were looking up
1908 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1909 type object.

2006
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002007- Issue #2975: When compiling several extension modules with Visual Studio 2008
2008 from the same python interpreter, some environment variables would grow
2009 without limit.
2010
Benjamin Peterson37346b22008-08-23 20:27:43 +00002011- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002048What's New in Python 2.6 beta 3?
2049================================
2050
Barry Warsaw07a4a382008-08-21 01:15:08 +00002051*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002052
2053Core and Builtins
2054-----------------
2055
Guido van Rossumf8402962008-08-20 15:01:50 +00002056- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2057 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2058 extensions do not automatically benefit from the class attribute
2059 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2060 to their tp_flags field if they care. This is a backwards
2061 compatibility feature; in 3.0, all types will use the cache by
2062 default.
2063
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002064- Keyword arguments can now follow starred arguments. (``f(a, *args,
2065 keyword=23)`` is now valid syntax.)
2066
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002067- ctypes function pointers that are COM methods have a boolean True
2068 value again.
2069
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002070- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2071 by denying s# to parse objects that have a releasebuffer procedure,
2072 and introducing s*.
2073
Georg Brandl1e13ea92008-08-11 09:07:59 +00002074- Issue #3537: Fix an assertion failure when an empty but presized dict
2075 object was stored in the freelist.
2076
Mark Dickinsonb6467572008-08-04 21:30:09 +00002077- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2078 ValueError consistently across platforms.
2079
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002080- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2081 (64bit Unix, for example), unichr() would truncate its argument and return
2082 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2083
Neal Norwitze7d8be82008-07-31 17:17:14 +00002084- Apply security patches from Apple.
2085
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002086- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2087 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2088
Antoine Pitrou92f82162008-07-25 22:22:08 +00002089- Issue #1819: function calls with several named parameters are now on
2090 average 35% faster (as measured by pybench).
2091
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002092- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2093 the python debugger steps into a class statement: the free variables (local
2094 variables defined in an outer scope) would be deleted from the outer scope.
2095
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002096- Issue #2620: Overflow checking when allocating or reallocating memory
2097 was not always being done properly in some python types and extension
2098 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2099 all been updated to perform better checks and places in the code that
2100 would previously leak memory on the error path when such an allocation
2101 failed have been fixed.
2102
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002103Library
2104-------
2105
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002106- Issue #3612: Added some missing basic types in ctypes.wintypes.
2107
Benjamin Petersone977ad42008-08-20 01:42:01 +00002108- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2109 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2110
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002111- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2112 version reported by these tools does not necessarily follow the python
2113 version numbering scheme, so the module is less strict when parsing it.
2114
Nick Coghlanf70385a2008-08-18 12:42:46 +00002115- Issue #2235: Added Py3k warnings for types which will become unhashable
2116 under the stricter __hash__ inheritance rules in 3.0. Several types
2117 which did not meet the rules for hash invariants and were already
2118 unhashable in 3.0 have now been explicitly flagged as unhashable in
2119 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2120 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2121
Brett Cannon88f801d2008-08-18 00:46:22 +00002122- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2123 imported into the module but exposed as part of the module's API.
2124

2126
Brett Cannon46225e72008-08-18 00:36:52 +00002127- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2130
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002131- Issue #3575: Incremental decoder's decode function now takes bytearray
2132 by using 's*' instead of 't#'.
2133
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002134- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002135 fails unicode conversion on 2nd parameter. (windows only)
2136
Facundo Batista94f243a2008-08-17 03:38:39 +00002137- Issue 2464. urllib2 now supports a malformation in the URL received
2138 in a redirect.
2139
Brett Cannonabe423e2008-08-16 21:47:07 +00002140- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002141 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002142
Facundo Batistaeb90b782008-08-16 14:44:07 +00002143- Issue #2776: fixed small issue when handling an URL with double slash
2144 after a 302 response in the case of not going through a proxy.
2145
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002146- Issue #2676: in the email package, content-type parsing was hanging on
2147 pathological input because of quadratic or exponential behaviour of a
2148 regular expression.
2149
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002150- Issue #3476: binary buffered reading through the new "io" library is now
2151 thread-safe.
2152
Brett Cannonbf3157b2008-08-14 05:00:03 +00002153- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2154 since mimetools itself is deprecated. Because modules are cached, all
2155 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2156
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002157- Issue #3134: shutil referenced undefined WindowsError symbol.
2158
Robert Schuppenies14646332008-08-10 11:01:53 +00002159- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2160 menu entries were not deleted.
2161
Brett Cannon83e81842008-08-09 23:30:55 +00002162- Copied the implementation of reduce() to _functools.reduce() to have a
2163 version that did not raise a DeprecationWarning under -3.
2164
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002165- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2166 a MemoryError rather than silently stop the iteration.
2167
Guido van Rossum59ce9012008-08-09 14:55:34 +00002168- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2169 to _sre.compile() will now be rejected. This should not affect anybody
2170 since the re.compile() function never generates invalid re-bytecode.
2171
Skip Montanaroa032bf42008-08-08 22:52:51 +00002172- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2173 upon first access it can be automatically initialized from the csv file if
2174 it wasn't initialized during instantiation.
2175
Brett Cannon3aa2a492008-08-06 22:28:09 +00002176- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2177 the reload() built-in has been removed.
2178
Brett Cannon7e30b672008-08-04 21:52:25 +00002179- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002180 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2188 raised an AttributeError.
2189
Benjamin Peterson01a24322008-07-28 23:35:27 +00002190- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002191 asking for a specific length. This problem only affected files opened
2192 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002193
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002194- Issue #3449: Update decimal module to use most recent specification
2195 (v. 1.68) and tests (v. 2.58) from IBM.

2216
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002217- Issue #3394: zipfile.writestr sets external attributes when passed a
2218 file name rather than a ZipInfo instance, so files are extracted with
2219 mode 0600 rather than 000 under Unix.
2220
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002221- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2222 argument in python 2.5, this broke code that subclassed Popen to include its
2223 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002233- Issue #2235: the C API function PyObject_HashNotImplemented and its
2234 interaction with the tp_hash slot (added in 2.6b2) are now documented
2235

2237 coverage of the lookup process for special methods. The disclaimers
2238 regarding lack of coverage of new-style classes have also been
2239 removed, since the coverage is now fairly reasonable.

2243================================
2244
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002245*Release date: 17-Jul-2008*
2246
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002247Core and Builtins
2248-----------------
2249
Georg Brandl3e483f62008-07-16 22:57:41 +00002250- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2251 its methods now allow for items objects that can be converted to
2252 an integer using operator.index().
2253
Mark Dickinson64b7e502008-07-16 09:40:03 +00002254- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2255 produced a ValueError instead of giving the correct float.
2256
Eric Smitha5fa5a22008-07-16 00:11:49 +00002257- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2258 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2259
Mark Dickinson7103aa42008-07-15 19:08:33 +00002260- Issue #3008: the float type has a new instance method 'float.hex'
2261 and a new class method 'float.fromhex' to convert floating-point
2262 numbers to and from hexadecimal strings, respectively.
2263
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002264- Issue #2235: __hash__ is once again inherited by default. To allow
2265 collections.Hashable to remain meaningful in the presence of the
2266 default hash implementation (object.__hash__), it is now possible
2267 to explicit block inheritance of hash by setting __hash__=None at
2268 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2269 level.
2270
Nick Coghlanb028f502008-07-13 14:52:36 +00002271- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2272 the parent module cannot be found while performing an absolute import.
2273 This means that an incorrectly defined __package__ attribute will
2274 now only prevent relative imports in that module rather than causing
2275 all imports from that module to fail.
2276
Nick Coghlan14ff9942008-07-08 14:21:42 +00002277- Issue #2517: Allow unicode messages in Exceptions again by correctly
2278 bypassing the instance dictionary when looking up __unicode__ on
2279 new-style classes.
2280
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002281- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2282 set to a custom object whose write() method happens to install
2283 another file in sys.stdout.

2290 arguments are now treated identically, making the behaviour easier

2292 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2293 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002748 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002749
2750 This is controlled by the configure argument ``--with-universal-archs``:

Georg Brandl3ee81df2008-05-17 18:14:43 +00002810- Issue #1631171: Re-implement the 'warnings' module in C (the
2811 original Python code has been kept as backup). This will allow for
2812 using the 'warning's machinery in such places as the parser where
2813 use of pure Python code is not possible. Both the ``showarning()``
2814 and ``formatwarning()`` gain an optional 'line' argument which is
2815 not called by default for backwards-compatibility reasons. Setting
2816 ``warnings.showwarning()`` to an implementation that lacks support
2817 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002880- Issue #2550: The approach used by client/server code for obtaining
2881 ports to listen on in network-oriented tests has been refined in an
2882 effort to facilitate running multiple instances of the entire
2883 regression test suite in parallel without issue.
2884 test_support.bind_port() has been fixed such that it will always
2885 return a unique port -- which wasn't always the case with the
2886 previous implementation, especially if socket options had been set
2887 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2888 new implementation of bind_port() will actually raise an exception
2889 if it is passed an AF_INET/SOCK_STREAM socket with either the
2890 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2891 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2892 the socket it's been passed. This currently only applies to
2893 Windows. This option prevents any other sockets from binding to the
2894 host/port we've bound to, thus removing the possibility of the
2895 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2896 when a second SOCK_STREAM socket binds and accepts to a host/port
2897 that's already been bound by another socket. The optional preferred
2898 port parameter to bind_port() has been removed. Under no
2899 circumstances should tests be hard coding ports!
2900
2901 test_support.find_unused_port() has also been introduced, which will
2902 pass a temporary socket object to bind_port() in order to obtain an
2903 unused port. The temporary socket object is then closed and
2904 deleted, and the port is returned. This method should only be used
2905 for obtaining an unused port in order to pass to an external program
2906 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2907 a parameter to a server-oriented class that doesn't give you direct
2908 access to the underlying socket used.
2909
2910 Finally, test_support.HOST has been introduced, which should be used
2911 for the host argument of any relevant socket calls (i.e. bind and
2912 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002913
2914 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002915 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002916 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2917 test_asynchat and test_socket_ssl.
2918
Georg Brandl3ee81df2008-05-17 18:14:43 +00002919 It is now possible for multiple instances of the regression test
2920 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003104 optional: it defaults to the traceback of the exception that is
3105 currently being handled (is mandatory to be in the middle of an
3106 exception, otherwise it raises ValueError).
Facundo Batistac54aec12008-03-08 16:50:27 +00003107
Jeffrey Yasskine75f59a2008-03-07 06:22:15 +00003108- Issue #1193577: A .shutdown() method has been added to SocketServers

Thomas Hellerf3c05592008-03-05 15:34:29 +00003121- Issue #1872: The struct module typecode for _Bool has been changed
3122 from 't' to '?'.
3123
Thomas Heller78b8f442008-03-05 14:53:39 +00003124- The bundled libffi copy is now in sync with the recently released
3125 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003126 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
3127 files are used. On all linux systems the --with-system-ffi
3128 configure option defaults to "yes".

3186Core and builtins
3187-----------------
3188
Fred Drakea8ee94b2008-03-01 02:45:07 +00003189- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003190 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003191
Georg Brandlad61bc82008-02-23 15:11:18 +00003192- Issue #2067: file.__exit__() now calls subclasses' close() method.
3193
3194- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003195
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003196- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003197 issue 215555 for a discussion.
3198
Eric Smitha73fbe72008-02-23 03:09:44 +00003199- Added the future_builtins module, which contains hex() and oct().
3200 These are the PEP 3127 version of these functions, designed to be
3201 compatible with the hex() and oct() builtins from Python 3.0. They
3202 differ slightly in their output formats from the existing, unchanged
3203 Python 2.6 builtins. The expected usage of the future_builtins
3204 module is:
3205 from future_builtins import hex, oct
3206
Eric Smith7ef40bf2008-02-20 23:34:22 +00003207- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3208 exponents for exponents with absolute value < 100. Follows C99
3209 standard. This is a change on Windows, which would use 3 digits.
3210 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3211 so that any alterations it does to the resulting string will be
3212 available in stringlib/formatter.h (for float.__format__).
3213
Eric Smith5a3c1352008-02-19 13:21:56 +00003214- Implemented PEP 3101, Advanced String Formatting. This adds a new
3215 builtin format(); a format() method for str and unicode; a
3216 __format__() method to object, str, unicode, int, long, float, and
3217 datetime; the class string.Formatter; and the C API
3218 PyObject_Format().
3219
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220- Fixed several potential crashes, all caused by specially crafted
3221 __del__ methods exploiting objects in temporarily inconsistent
3222 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003223
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003224- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003225 prevent a possible crash: an Abstract Base Class would try to access
3226 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003227
Georg Brandl3ee81df2008-05-17 18:14:43 +00003228- Fixed repr() and str() of complex numbers with infinity or nan as
3229 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003230
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231- Clear all free lists during a gc.collect() of the highest generation
3232 in order to allow pymalloc to free more arenas. Python may give back
3233 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003234
Georg Brandl3ee81df2008-05-17 18:14:43 +00003235- Issue #2045: Fix an infinite recursion triggered when printing a
3236 subclass of collections.defaultdict, if its default_factory is set
3237 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003238
Christian Heimesf75dbef2008-02-08 00:11:31 +00003239- Fixed a minor memory leak in dictobject.c. The content of the free
3240 list was not freed on interpreter shutdown.
3241
Georg Brandl3ee81df2008-05-17 18:14:43 +00003242- Limit free list of method and builtin function objects to 256
3243 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003244
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3246 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003247 to compact the internal free lists of pre-allocted ints and floats.
3248
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3250 calls. Python expected the return type int but the fork familie
3251 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003252
Georg Brandl3ee81df2008-05-17 18:14:43 +00003253- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3254 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003255
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3257 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003258
Georg Brandl3ee81df2008-05-17 18:14:43 +00003259- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3260 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003261
Georg Brandl3ee81df2008-05-17 18:14:43 +00003262- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3263 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003264
Georg Brandl3ee81df2008-05-17 18:14:43 +00003265- Patch #1473257: generator objects gain a gi_code attribute. This is
3266 the same object as the func_code attribute of the function that
3267 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003268
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269- Issue #1920: "while 0" statements were completely removed by the
3270 compiler, even in the presence of an "else" clause, which is
3271 supposed to be run when the condition is false. Now the compiler
3272 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003273
Guido van Rossumeead05f2008-01-24 18:21:02 +00003274- A few crashers fixed: weakref_in_del.py (issue #1377858);
3275 loosing_dict_ref.py (issue #1303614, test67.py);
3276 borrowed_ref_[34].py (not in tracker).
3277
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003278- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003279 suppressed while an extension is loaded by calling SetErrorMode in
3280 dynload_win.c. The error is still reported properly.
3281
Georg Brandl3ee81df2008-05-17 18:14:43 +00003282- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003283 several extension methods and modules do not work without unicode
3284 support.
3285
Georg Brandl26543b12008-01-21 18:36:51 +00003286- Issue #1882: when compiling code from a string, encoding cookies in the
3287 second line of code were not always recognized correctly.
3288
Georg Brandl14404b62008-01-19 19:27:05 +00003289- Issue #1679: "0x" was taken as a valid integer literal.
3290
Georg Brandl6caad7d2008-01-26 14:19:22 +00003291- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003292 added.
3293
Christian Heimesc94e2b52008-01-14 04:13:37 +00003294- sys.float_info / PyFloat_GetInfo: The floating point information
3295 object was converted from a dict to a specialized structseq object.
3296
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297- Patch #1816: Added sys.flags structseq. It exposes the status of
3298 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003299
Georg Brandl3ee81df2008-05-17 18:14:43 +00003300- Objects/structseq.c: Implemented new structseq representation. The
3301 patch makes structseqs (e.g. the return value of os.stat) more
3302 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003303
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304- Patch #1700288: added a type attribute cache that caches method
3305 accesses, resulting in speedups in heavily object-oriented code.

3313 envvar and sys.dont_write_bytecode attribute. All these can be set
3314 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003315
Georg Brandl3ee81df2008-05-17 18:14:43 +00003316- Improve some exception messages when Windows fails to load an
3317 extension module. Now we get for example '%1 is not a valid Win32
3318 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003319

3323 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003324
Christian Heimes0a8143f2007-12-18 23:22:54 +00003325- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003326 and INF. float("nan"), float("inf") and float("-inf") now work on
3327 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003328
Georg Brandl3ee81df2008-05-17 18:14:43 +00003329- Compiler now generates simpler and faster code for dictionary
3330 literals. The oparg for BUILD_MAP now indicates an estimated
3331 dictionary size. There is a new opcode, STORE_MAP, for adding
3332 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003361- Patch #1739468: Directories and zipfiles containing a __main__.py
3362 file can now be directly executed by passing their name to the
3363 interpreter. The directory/zipfile is automatically inserted as the
3364 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- Issue #1265: Fix a problem with sys.settrace, if the tracing
3367 function uses a generator expression when at the same time the
3368 executed code is closing a paused generator.

3375
Georg Brandl3ee81df2008-05-17 18:14:43 +00003376- The enumerate() builtin function is no longer bounded to sequences
3377 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3378 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003379
Georg Brandl3ee81df2008-05-17 18:14:43 +00003380- Issue #1686386: Tuple's tp_repr did not take into account the
3381 possibility of having a self-referential tuple, which is possible
3382 from C code. Nor did object's tp_str consider that a type's tp_str
3383 could do something that could lead to an inifinite recursion.
3384 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3385 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Issue #1164: It was possible to trigger deadlock when using the
3388 'print' statement to write to a file since the GIL was not released
3389 as needed. Now PyObject_Print() does the right thing along with
3390 various tp_print implementations of the built-in types and those in
3391 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003392
Georg Brandl3ee81df2008-05-17 18:14:43 +00003393- Issue #1147: Exceptions were directly allowing string exceptions in

3395 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00003400- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003401 PyObject_Call() never calling back out to Python code to trigger
3402 recursion depth updates/checks. Required the creation of a static
3403 RuntimeError instance in case normalizing an exception put the
3404 recursion check value past its limit. Fixes crashers
3405 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003420- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003421 __*__ attributes. (Some already existed, e.g., __doc__ and
3422 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003423
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003424- Add -3 option to the interpreter to warn about features that are

3428 calls.
3429
Collin Winter62903052007-05-18 23:11:24 +00003430- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431 "except E as target:". This is to provide forwards compatibility
3432 with Python 3.0.

3438
Vinay Sajip8549ce32007-05-06 17:53:37 +00003439- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003440 setting a plain string, ie don't expand to single letter identifiers.
3441
Raymond Hettinger13936692007-04-11 18:40:58 +00003442- Request #1191699: Slices can now be pickled.
3443
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003444- Request #1193128: str.translate() now allows a None argument for

3446 remaining characters.
3447
Georg Brandl5cb76c12007-03-21 09:00:39 +00003448- Patch #1682205: a TypeError while unpacking an iterable is no longer

3452
Guido van Rossum143b5642007-03-23 04:58:42 +00003453- Bug #1683368: The object.__init__() and object.__new__() methods are
3454 now stricter in rejecting excess arguments. The only time when
3455 either allows excess arguments is when it is not overridden and the
3456 other one is. For backwards compatibility, when both are
3457 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003458 warning later). Also, type.__init__() insists on the same signature
3459 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003460
Georg Brandl3ee81df2008-05-17 18:14:43 +00003461- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3462 object to complex using its __complex__() method before falling back
3463 to the __float__() method. Therefore, the functions in the cmath
3464 module now can operate on objects that define a __complex__()
3465 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003466
Georg Brandl3ee81df2008-05-17 18:14:43 +00003467- Patch #1623563: allow __class__ assignment for classes with
3468 __slots__. The old and the new class are still required to have the
3469 same slot names.

3476 its type.

3482
Georg Brandl7b9c5552007-03-12 14:30:05 +00003483- Bug #1678647: write a newline after printing an exception in any
3484 case, even when converting the value to a string failed.
3485
Georg Brandl871f1bc2007-03-12 13:17:36 +00003486- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487 its argument, if it exists. If not, it will work like before. This
3488 allows customizing the output of dir() in the presence of a
3489 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- Patch #1491866: change the complex() constructor to allow
3498 parthensized forms. This means complex(repr(x)) now works instead of
3499 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003500
Georg Brandlaa2321b2007-03-07 00:40:28 +00003501- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003502 makes the filenames the warning module prints much more sensible
3503 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003516- Patch #1674228: when assigning a slice (old-style), check for the
3517 sq_ass_slice instead of the sq_slice slot.
3518
Georg Brandl3ee81df2008-05-17 18:14:43 +00003519- When printing an unraisable error, don't print exceptions. before
3520 the name. This duplicates the behavior whening normally printing
3521 exceptions.

3578
Armin Rigo7ccbca92006-10-04 12:17:45 +00003579- A number of places, including integer negation and absolute value,

Georg Brandl3ee81df2008-05-17 18:14:43 +00004089 are set for invalid interpolation sequences that would lead to

4146 TestCase and TestSuite subclasses (not instances) are no longer
4147 accepted in TestSuite.addTest(). This should cause no
4148 incompatibility since it never made sense with ordinary subclasses
4149 -- the failure just occurred later, with a more cumbersome
4150 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004431- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4432 with RFC 3207 and forgets any knowledge obtained from the server not
4433 obtained from the TLS negotiation itself. Patch contributed by Bill
4434 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004435
Georg Brandl3ee81df2008-05-17 18:14:43 +00004436- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004437 that the SMTP.starttls() caller no longer needs to call ehlo()
4438 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004439 does not claim to support starttls. Adds the
4440 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4441 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004495- itertools.chain() now has an alternate constructor,

4521 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4522 silently miscode subclasses of those types. Now, it raises a
4523 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004524

Georg Brandl3ee81df2008-05-17 18:14:43 +00004539 time so that opening a database previously created with the DB_DUP
4540 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4541 opens. Specifically: dictionary assignment to a DB object will
4542 replace all values for a given key when the database allows
4543 duplicate values. DB users should use DB.put(k, v) when they want
4544 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004545

4551 characters with ASCII value less than 32. Also, it correctly quotes
4552 dots only if they occur on a single line, as opposed to the previous
4553 behavior of quoting dots if they are the second character of any
4554 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004555

4819 without this option!
4820
Martin v. Löwis63bf1492007-11-12 05:14:05 +00004821- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
4822
Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004823- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004824 periodic threadstate and signal checking in tight loops. By
4825 default, this option is turned-off. It should only be enabled in
4826 debugged, performance critical applications.

4877-----
4878
Georg Brandl3ee81df2008-05-17 18:14:43 +00004879- Unified naming convention for free lists and their limits. All free
4880 lists in Object/ are named ``free_list``, the counter ``numfree``
4881 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4882 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004883
Georg Brandl3ee81df2008-05-17 18:14:43 +00004884- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4885 to ``PyTuple_SetItem``, it can be used to populate a brand new
4886 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004887

4895
4896- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4897 ``PyFloat_GetInfo()`` to the float API.
4898
Georg Brandl3ee81df2008-05-17 18:14:43 +00004899- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4900 of w# format code incorrectly truncated the length to an int, even
4901 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4902 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004903
Georg Brandl3ee81df2008-05-17 18:14:43 +00004904- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4922- Fix some leftovers from the conversion from int to Py_ssize_t
4923 (relevant to strings and sequences of more than 2**31 items).
4924
4925- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4926 outside of pystate.c and should not be necessary.
4927
Georg Brandl3ee81df2008-05-17 18:14:43 +00004928- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4929 absolute imports. In earlier versions they might have used relative
4930 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004931
Georg Brandl3ee81df2008-05-17 18:14:43 +00004932- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4933 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004934
Georg Brandl3ee81df2008-05-17 18:14:43 +00004935- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4943 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4944 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4945 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004946

Georg Brandl3ee81df2008-05-17 18:14:43 +00004960- Removed the macfs module. It had been deprecated since Python 2.5.
4961 This lead to the deprecation of macostools.touched() as it relied
