Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000027- Issue #7419: setlocale() could crash the interpreter on Windows when called
28 with invalid values.
29
Eric Smithc4ab8332009-11-29 17:40:57 +000030- Issue #3382: 'F' formatting for float and complex now convert the
31 result to upper case. This only affects 'inf' and 'nan', since 'f'
32 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000033
Mark Dickinson9dd5e162009-11-23 20:54:09 +000034- Remove switch from "%f" formatting to "%g" formatting for floats
35 larger than 1e50 in absolute value.
36
Mark Dickinson18cfada2009-11-23 18:46:41 +000037- Remove restrictions on precision when formatting floats. E.g.,
38 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
39 requested 120 significant digits instead.
40
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000041- Add Py3k warnings for parameter names in parenthesis.
42
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000043- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000044
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000045- Issue #7085: Fix crash when importing some extensions in a thread
46 on MacOSX 10.6.
47
Mark Dickinsonb678de82009-11-19 18:41:49 +000048- Issue #7117: repr(x) for a float x returns a result based on the
49 shortest decimal string that's guaranteed to round back to x under
50 correct rounding (with round-half-to-even rounding mode).
51 Previously it gave a string based on rounding x to 17 decimal digits.
52 repr(x) for a complex number behaves similarly. On platforms where
53 the correctly-rounded strtod and dtoa code is not supported (see below),
54 repr is unchanged.
55
56- Issue #7117: On almost all platforms: float-to-string and
57 string-to-float conversions within Python are now correctly rounded.
58 Places these conversions occur include: str for floats and complex
59 numbers; the float and complex constructors; old-style and new-style
60 numeric formatting; serialization and deserialization of floats and
61 complex numbers using marshal, pickle and json; parsing of float and
62 imaginary literals in Python code; Decimal-to-float conversion.
63
64 The conversions use a Python-adapted version of David Gay's
65 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
66 functions. This code is supported on Windows, and on Unix-like
67 platforms using gcc, icc or suncc as the C compiler. There may be a
68 small number of platforms on which correct operation of this code
69 cannot be guaranteed, so the code is not used: notably, this applies
70 to platforms where the C double format is not IEEE 754 binary64, and
71 to platforms on x86 hardware where the x87 FPU is set to 64-bit
72 precision and Python's configure script is unable to determine how
73 to change the FPU precision. On these platforms conversions use the
74 platform strtod and dtoa, as before.
75
Mark Dickinsonbd15a062009-11-18 19:33:35 +000076- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000077 now uses the correctly-rounded string <-> float conversions
78 described above (when available), and so produces correctly rounded
79 results that will display nicely under the float repr. There are
80 two related small changes: (1) round now accepts any class with an
81 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000082 floats for the second argument), and (2) an excessively large second
83 integer argument (e.g., round(1.234, 10**100)) no longer raises an
84 exception.
85
Philip Jenveyfab8be22009-11-17 02:42:26 +000086- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
87
Benjamin Petersone36199b2009-11-12 23:39:44 +000088- Fix several issues with compile(). The input can now contain Windows and Mac
89 newlines and is no longer required to end in a newline.
90

92 unicode string.
93
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +000094- Issue #7244: itertools.izip_longest() no longer ignores exceptions

213 statement and correctly lookup the __enter__ and __exit__ special methods.
214
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000215- Issue #5829: complex("1e500") no longer raises OverflowError. This
216 makes it consistent with float("1e500") and interpretation of real

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000226- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
227 (1) inf and nan strings with trailing whitespace were incorrectly
228 rejected; (2) parsing of strings representing infinities and nans
229 was locale aware; and (3) the interpretation of fromhex('-nan')
230 didn't match that of float('-nan').
231
Eric Smitha985a3a2009-05-05 18:26:08 +0000232- Issue #5920: For float.__format__, change the behavior with the
233 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
234 to be like 'g' but with at least one decimal point and with a
235 default precision of 12. Previously, the behavior the same but with
236 a default precision of 6. This more closely matches str(), and
237 reduces surprises when adding alignment flags to the empty
238 presentation type. This also affects the new complex.__format__ in
239 the same way.
240
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000241- Issue #5890: in subclasses of 'property' the __doc__ attribute was
242 shadowed by classtype's, even if it was None. property now

264
Mark Dickinson95bc9802009-04-24 12:46:53 +0000265- Issue #5816: complex(repr(z)) now recovers z exactly, even when
266 z involves nans, infs or negative zeros.
267
Eric Smithaca19e62009-04-22 13:29:05 +0000268- Implement PEP 378, Format Specifier for Thousands Separator, for
269 floats, ints, and longs.
270
271- Issue #5515: 'n' formatting for ints, longs, and floats handles
272 leading zero formatting poorly.
273
274- Issue #5772: For float.__format__, don't add a trailing ".0" if
275 we're using no type code and we have an exponent.

282
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000283- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000284 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000285
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000286- Issue #5759: float() didn't call __float__ on str subclasses.

304 untrackable objects are not tracked by the garbage collector. This can
305 reduce the size of collections and therefore the garbage collection overhead
306 on long-running programs, depending on their particular use of datatypes.
307
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000308- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

310 are now between 50% and 150% faster.
311
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000312- Issue #4258: Make it possible to use base 2**30 instead of base
313 2**15 for the internal representation of integers, for performance
314 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
315 --enable-big-digits option to configure, which overrides the
316 default. Add sys.long_info structseq to provide information about
317 the internal format.
318
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000319- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
320 result traceback.__members__ no longer exists.)
321
Mark Dickinson6b265f12009-03-18 16:07:26 +0000322- Issue #4474: PyUnicode_FromWideChar now converts characters outside
323 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
324 and sizeof(Py_UNICODE) == 2.
325
Eric Smith6f42edb2009-03-14 11:57:26 +0000326- Issue #5237: Allow auto-numbered fields in str.format(). For
327 example: '{} {}'.format(1, 2) == '1 2'.
328
Brett Cannon6c4cff02009-03-11 04:51:06 +0000329- Issue #3652: Make the 'line' argument for warnings.showwarning() a
330 requirement. Means the DeprecationWarning from Python 2.6 can go away.
331
Eric Smithe9fb6862009-02-20 14:02:36 +0000332- Issue #5247: Improve error message when unknown format codes are
333 used when using str.format() with str, unicode, long, int, and
334 float arguments.
335
Raymond Hettinger08259e82009-02-18 23:10:19 +0000336- Running Python with the -3 option now also warns about classic division
337 for ints and longs.
338
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000339- Issue #5260: Long integers now consume less memory: average
340 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
341 on a 64-bit system.
342
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000343- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

Mark Dickinsonc97c9092009-02-09 14:18:43 +0000346- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
347 it now forces its argument to double before testing for infinity.
348
Benjamin Petersone18ef192009-01-20 14:21:16 +0000349- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
350
Georg Brandl29c6a282009-04-05 20:23:13 +0000351- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000352 were suppressing all exceptions. These include list(), filter(), map(),
353 zip(), and bytearray().
354
Benjamin Peterson596d3062009-01-19 15:42:23 +0000355- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
356 functions.
357
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000358- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

362
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000363- Issue #4935: The overflow checking code in the expandtabs() method common
364 to str, bytes and bytearray could be optimized away by the compiler, letting
365 the interpreter segfault instead of raising an error.
366
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000367- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000374- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
375 collecting the oldest generation) so that allocating lots of objects without
376 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000377 Martin von Löwis at

381
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000382- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
383 an existing .py counterpart, override the co_filename attributes of all
384 code objects if the original filename is obsolete (which can happen if the
385 file has been renamed, moved, or if it is accessed through different paths).
386 Patch by Ziga Seilnacht and Jean-Paul Calderone.
387
Martin v. Löwis5344c992009-01-02 20:32:55 +0000388- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000390- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
391 file with `str' filename on Windows.
392
Antoine Pitrouaa687902009-01-01 14:11:22 +0000393- Issue #3680: Reference cycles created through a dict, set or deque iterator
394 did not get collected.
395
Nick Coghlan180e4002008-12-30 01:18:48 +0000396- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
397 where the tp_hash and tp_dict slots are both NULL.
398
Benjamin Peterson7af65562008-12-29 17:56:58 +0000399- Issue #4764: With io.open, IOError.filename is set when trying to open a

401
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000402- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
403 systems.
404
Georg Brandl6425a2f2008-12-28 11:54:53 +0000405- Issue #4759: None is now allowed as the first argument of
406 bytearray.translate(). It was always allowed for bytes.translate().
407
Skip Montanarof205c132008-12-23 03:30:15 +0000408- Added test case to ensure attempts to read from a file opened for writing
409 fail.
410
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000411- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

419
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000420- Issue #4597: Fixed exception handling when the __exit__ function of a
421 context manager returns a value that cannot be converted to a bool.
422
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000423- Issue #4597: Fixed several opcodes that weren't always propagating
424 exceptions.
425
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000426- Issue #4445: Replace "sizeof(PyStringObject)" with
427 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
428 str instances. On a typical machine this saves 3 bytes of memory
429 (on average) per string allocation.
430
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000431- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
432 interpreter to abort ("Fatal Python error: Could not reset the stack!")
433 instead of throwing a MemoryError.
434
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000435- Issue #3689: The list reversed iterator now supports __length_hint__
436 instead of __len__. Behavior now matches other reversed iterators.
437
Benjamin Petersonc078f922008-11-21 22:27:24 +0000438- Issue #4367: Python would segfault during compiling when the unicodedata

440
Vinay Sajip213faca2008-12-03 23:22:58 +0000441- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000442 method on file objects with closefd=False. The file descriptor is still
443 kept open but the file object behaves like a closed file. The ``FileIO``
444 object also got a new readonly attribute ``closefd``.
445
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000446- Issue #4348: Some bytearray methods returned that didn't cause any change to
447 the bytearray, returned the same bytearray instead of a copy.
448
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000449- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
450

454
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000455- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

457
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000458- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
459 method does not return iterators for the 4th and 5th items.
460
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000461- Issue #4209: Enabling unicode_literals and the print_function in the same
462 __future__ import didn't work.
463
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000464- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000465 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000466
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000467- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
468 returned a path longer than MAX_PATH. (But It's doubtful this code path is
469 really executed because I cannot move to such directory on win2k)
470
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000471- Issue #4069: When set.remove(element) is used with a set element, the element
472 is temporarily replaced with an equivalent frozenset. But the eventual
473 KeyError would always report the empty frozenset([]) as the missing key. Now
474 it correctly refers to the initial element.

487
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000488- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
489 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000491- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
492 returned them on 64bit platforms.
493
Walter Dörwalded960ac2009-05-03 22:36:33 +0000494- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
495 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
496 step. This avoids problems with counting UTF-8 bytes that ignores the effect
497 of using the replace error handler in PyUnicode_DecodeUTF8().
498
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000499- Issue #3739: The unicode-internal encoder now reports the number of characters
500 consumed like any other encoder (instead of the number of bytes).
501
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000502- Issue #2422: When compiled with the ``--with-valgrind`` option, the
503 pymalloc allocator will be automatically disabled when running under
504 Valgrind. This gives improved memory leak detection when running
505 under Valgrind, while taking advantage of pymalloc at other times.

1729 leak-chasing test runs give sensible results. The previous method of
1730 reaping threads could return successfully while some Thread objects were

1750 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

1758 it easy to import both normal and optimised versions of modules.
1759 test_heapq and test_warnings have been adjusted to use it, tests for
1760 other modules with both C and Python implementations in the stdlib
1761 can be adjusted to use it over time.

1873
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001874- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1875 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1876 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1877 ``printf`` function, whereas PyString_FromFormat has an independent
1878 implementation and uses "%zd" on all platforms for size_t values.
1879 This makes a difference on win64, where ``printf`` needs "%Id" to display
1880 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001882- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1886 object; previously an int would be returned for small values. the __long__
1887 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00001896 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001897 was correctly parsed but parsing of subsequent arguments failed.
1898
Vinay Sajip35e3b032008-09-01 14:33:59 +00001899- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001900 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1901 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1902 when given a tuple of classes as second argument, were looking up
1903 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1904 type object.

2001
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002002- Issue #2975: When compiling several extension modules with Visual Studio 2008
2003 from the same python interpreter, some environment variables would grow
2004 without limit.
2005
Benjamin Peterson37346b22008-08-23 20:27:43 +00002006- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002043What's New in Python 2.6 beta 3?
2044================================
2045
Barry Warsaw07a4a382008-08-21 01:15:08 +00002046*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002047
2048Core and Builtins
2049-----------------
2050
Guido van Rossumf8402962008-08-20 15:01:50 +00002051- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2052 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2053 extensions do not automatically benefit from the class attribute
2054 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2055 to their tp_flags field if they care. This is a backwards
2056 compatibility feature; in 3.0, all types will use the cache by
2057 default.
2058
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002059- Keyword arguments can now follow starred arguments. (``f(a, *args,
2060 keyword=23)`` is now valid syntax.)
2061
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002062- ctypes function pointers that are COM methods have a boolean True
2063 value again.
2064
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002065- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2066 by denying s# to parse objects that have a releasebuffer procedure,
2067 and introducing s*.
2068
Georg Brandl1e13ea92008-08-11 09:07:59 +00002069- Issue #3537: Fix an assertion failure when an empty but presized dict
2070 object was stored in the freelist.
2071
Mark Dickinsonb6467572008-08-04 21:30:09 +00002072- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2073 ValueError consistently across platforms.
2074
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002075- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2076 (64bit Unix, for example), unichr() would truncate its argument and return
2077 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2078
Neal Norwitze7d8be82008-07-31 17:17:14 +00002079- Apply security patches from Apple.
2080
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002081- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2082 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2083
Antoine Pitrou92f82162008-07-25 22:22:08 +00002084- Issue #1819: function calls with several named parameters are now on
2085 average 35% faster (as measured by pybench).
2086
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002087- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2088 the python debugger steps into a class statement: the free variables (local
2089 variables defined in an outer scope) would be deleted from the outer scope.
2090
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002091- Issue #2620: Overflow checking when allocating or reallocating memory
2092 was not always being done properly in some python types and extension
2093 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2094 all been updated to perform better checks and places in the code that
2095 would previously leak memory on the error path when such an allocation
2096 failed have been fixed.
2097
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002098Library
2099-------
2100
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002101- Issue #3612: Added some missing basic types in ctypes.wintypes.
2102
Benjamin Petersone977ad42008-08-20 01:42:01 +00002103- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2104 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2105
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002106- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2107 version reported by these tools does not necessarily follow the python
2108 version numbering scheme, so the module is less strict when parsing it.
2109
Nick Coghlanf70385a2008-08-18 12:42:46 +00002110- Issue #2235: Added Py3k warnings for types which will become unhashable
2111 under the stricter __hash__ inheritance rules in 3.0. Several types
2112 which did not meet the rules for hash invariants and were already
2113 unhashable in 3.0 have now been explicitly flagged as unhashable in
2114 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2115 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2116
Brett Cannon88f801d2008-08-18 00:46:22 +00002117- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2118 imported into the module but exposed as part of the module's API.
2119
Brett Cannon7b96f072008-08-18 00:41:11 +00002120- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2121
Brett Cannon46225e72008-08-18 00:36:52 +00002122- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002124- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2125
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002126- Issue #3575: Incremental decoder's decode function now takes bytearray
2127 by using 's*' instead of 't#'.
2128
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002129- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002130 fails unicode conversion on 2nd parameter. (windows only)
2131
Facundo Batista94f243a2008-08-17 03:38:39 +00002132- Issue 2464. urllib2 now supports a malformation in the URL received
2133 in a redirect.
2134
Brett Cannonabe423e2008-08-16 21:47:07 +00002135- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002136 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002137
Facundo Batistaeb90b782008-08-16 14:44:07 +00002138- Issue #2776: fixed small issue when handling an URL with double slash
2139 after a 302 response in the case of not going through a proxy.
2140
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002141- Issue #2676: in the email package, content-type parsing was hanging on
2142 pathological input because of quadratic or exponential behaviour of a
2143 regular expression.
2144
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002145- Issue #3476: binary buffered reading through the new "io" library is now
2146 thread-safe.
2147
Brett Cannonbf3157b2008-08-14 05:00:03 +00002148- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2149 since mimetools itself is deprecated. Because modules are cached, all
2150 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2151
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002152- Issue #3134: shutil referenced undefined WindowsError symbol.
2153
Robert Schuppenies14646332008-08-10 11:01:53 +00002154- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2155 menu entries were not deleted.
2156
Brett Cannon83e81842008-08-09 23:30:55 +00002157- Copied the implementation of reduce() to _functools.reduce() to have a
2158 version that did not raise a DeprecationWarning under -3.
2159
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002160- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2161 a MemoryError rather than silently stop the iteration.
2162
Guido van Rossum59ce9012008-08-09 14:55:34 +00002163- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2164 to _sre.compile() will now be rejected. This should not affect anybody
2165 since the re.compile() function never generates invalid re-bytecode.
2166
Skip Montanaroa032bf42008-08-08 22:52:51 +00002167- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2168 upon first access it can be automatically initialized from the csv file if
2169 it wasn't initialized during instantiation.
2170
Brett Cannon3aa2a492008-08-06 22:28:09 +00002171- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2172 the reload() built-in has been removed.
2173
Brett Cannon7e30b672008-08-04 21:52:25 +00002174- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002175 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2179 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2180 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002182- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2183 raised an AttributeError.
2184
Benjamin Peterson01a24322008-07-28 23:35:27 +00002185- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002186 asking for a specific length. This problem only affected files opened
2187 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002188
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002189- Issue #3449: Update decimal module to use most recent specification
2190 (v. 1.68) and tests (v. 2.58) from IBM.
2191
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002192- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2200
2201- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2202 invalid arguments.
2203
2204- Issue #3302: Fix several crashes when calling locale's gettext functions
2205 with None arguments.
2206
2207- Issue #3389: Allow resolving dotted names for handlers in logging
2208 configuration files.
2209
2210- Deprecate the sunaudio module for removal in Python 3.0.
2211
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002212- Issue #3394: zipfile.writestr sets external attributes when passed a
2213 file name rather than a ZipInfo instance, so files are extracted with
2214 mode 0600 rather than 000 under Unix.
2215
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002216- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2217 argument in python 2.5, this broke code that subclassed Popen to include its
2218 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2227
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002228- Issue #2235: the C API function PyObject_HashNotImplemented and its
2229 interaction with the tp_hash slot (added in 2.6b2) are now documented
2230
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002231- Issue #643841: The language reference now provides more detailed
2232 coverage of the lookup process for special methods. The disclaimers
2233 regarding lack of coverage of new-style classes have also been
2234 removed, since the coverage is now fairly reasonable.

2238================================
2239
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002240*Release date: 17-Jul-2008*
2241
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002242Core and Builtins
2243-----------------
2244
Georg Brandl3e483f62008-07-16 22:57:41 +00002245- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2246 its methods now allow for items objects that can be converted to
2247 an integer using operator.index().
2248
Mark Dickinson64b7e502008-07-16 09:40:03 +00002249- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2250 produced a ValueError instead of giving the correct float.
2251
Eric Smitha5fa5a22008-07-16 00:11:49 +00002252- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2253 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2254
Mark Dickinson7103aa42008-07-15 19:08:33 +00002255- Issue #3008: the float type has a new instance method 'float.hex'
2256 and a new class method 'float.fromhex' to convert floating-point
2257 numbers to and from hexadecimal strings, respectively.
2258
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002259- Issue #2235: __hash__ is once again inherited by default. To allow
2260 collections.Hashable to remain meaningful in the presence of the
2261 default hash implementation (object.__hash__), it is now possible
2262 to explicit block inheritance of hash by setting __hash__=None at
2263 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2264 level.
2265
Nick Coghlanb028f502008-07-13 14:52:36 +00002266- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2267 the parent module cannot be found while performing an absolute import.
2268 This means that an incorrectly defined __package__ attribute will
2269 now only prevent relative imports in that module rather than causing
2270 all imports from that module to fail.
2271
Nick Coghlan14ff9942008-07-08 14:21:42 +00002272- Issue #2517: Allow unicode messages in Exceptions again by correctly
2273 bypassing the instance dictionary when looking up __unicode__ on
2274 new-style classes.
2275
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002276- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2277 set to a custom object whose write() method happens to install
2278 another file in sys.stdout.
2279
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002280- Issue #3088: Corrected a race condition in classes derived from

2282 another thread's dictionary.
2283
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002284- Issue #3004: Minor change to slice.indices(): the start and stop
2285 arguments are now treated identically, making the behaviour easier
2286 to describe and understand. For example, slice(None, -10,
2287 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2288 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

2742 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002743 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002744
2745 This is controlled by the configure argument ``--with-universal-archs``:
2746
2747 - ``--with-universal-archs=all``: install 4-way universal
2748
2749 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2750
2751 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2752
2753 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002805- Issue #1631171: Re-implement the 'warnings' module in C (the
2806 original Python code has been kept as backup). This will allow for
2807 using the 'warning's machinery in such places as the parser where
2808 use of pure Python code is not possible. Both the ``showarning()``
2809 and ``formatwarning()`` gain an optional 'line' argument which is
2810 not called by default for backwards-compatibility reasons. Setting
2811 ``warnings.showwarning()`` to an implementation that lacks support
2812 for the ``line`` argument will raise a DeprecationWarning.

2836
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002837- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00002875- Issue #2550: The approach used by client/server code for obtaining
2876 ports to listen on in network-oriented tests has been refined in an
2877 effort to facilitate running multiple instances of the entire
2878 regression test suite in parallel without issue.
2879 test_support.bind_port() has been fixed such that it will always
2880 return a unique port -- which wasn't always the case with the
2881 previous implementation, especially if socket options had been set
2882 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2883 new implementation of bind_port() will actually raise an exception
2884 if it is passed an AF_INET/SOCK_STREAM socket with either the
2885 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2886 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2887 the socket it's been passed. This currently only applies to
2888 Windows. This option prevents any other sockets from binding to the
2889 host/port we've bound to, thus removing the possibility of the
2890 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2891 when a second SOCK_STREAM socket binds and accepts to a host/port
2892 that's already been bound by another socket. The optional preferred
2893 port parameter to bind_port() has been removed. Under no
2894 circumstances should tests be hard coding ports!
2895
2896 test_support.find_unused_port() has also been introduced, which will
2897 pass a temporary socket object to bind_port() in order to obtain an
2898 unused port. The temporary socket object is then closed and
2899 deleted, and the port is returned. This method should only be used
2900 for obtaining an unused port in order to pass to an external program
2901 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2902 a parameter to a server-oriented class that doesn't give you direct
2903 access to the underlying socket used.
2904
2905 Finally, test_support.HOST has been introduced, which should be used
2906 for the host argument of any relevant socket calls (i.e. bind and
2907 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002908
2909 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002910 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002911 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2912 test_asynchat and test_socket_ssl.
2913
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914 It is now possible for multiple instances of the regression test
2915 suite to run in parallel without issue.

3182-----------------
3183
Fred Drakea8ee94b2008-03-01 02:45:07 +00003184- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003185 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003187- Issue #2067: file.__exit__() now calls subclasses' close() method.
3188
3189- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003190
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003191- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003192 issue 215555 for a discussion.
3193
Eric Smitha73fbe72008-02-23 03:09:44 +00003194- Added the future_builtins module, which contains hex() and oct().
3195 These are the PEP 3127 version of these functions, designed to be
3196 compatible with the hex() and oct() builtins from Python 3.0. They
3197 differ slightly in their output formats from the existing, unchanged
3198 Python 2.6 builtins. The expected usage of the future_builtins
3199 module is:
3200 from future_builtins import hex, oct
3201
Eric Smith7ef40bf2008-02-20 23:34:22 +00003202- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3203 exponents for exponents with absolute value < 100. Follows C99
3204 standard. This is a change on Windows, which would use 3 digits.
3205 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3206 so that any alterations it does to the resulting string will be
3207 available in stringlib/formatter.h (for float.__format__).
3208
Eric Smith5a3c1352008-02-19 13:21:56 +00003209- Implemented PEP 3101, Advanced String Formatting. This adds a new
3210 builtin format(); a format() method for str and unicode; a
3211 __format__() method to object, str, unicode, int, long, float, and
3212 datetime; the class string.Formatter; and the C API
3213 PyObject_Format().
3214
Georg Brandl3ee81df2008-05-17 18:14:43 +00003215- Fixed several potential crashes, all caused by specially crafted
3216 __del__ methods exploiting objects in temporarily inconsistent
3217 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003218
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003219- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220 prevent a possible crash: an Abstract Base Class would try to access
3221 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003222
Georg Brandl3ee81df2008-05-17 18:14:43 +00003223- Fixed repr() and str() of complex numbers with infinity or nan as
3224 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003225
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226- Clear all free lists during a gc.collect() of the highest generation
3227 in order to allow pymalloc to free more arenas. Python may give back
3228 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003229
Georg Brandl3ee81df2008-05-17 18:14:43 +00003230- Issue #2045: Fix an infinite recursion triggered when printing a
3231 subclass of collections.defaultdict, if its default_factory is set
3232 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003233
Christian Heimesf75dbef2008-02-08 00:11:31 +00003234- Fixed a minor memory leak in dictobject.c. The content of the free
3235 list was not freed on interpreter shutdown.
3236
Georg Brandl3ee81df2008-05-17 18:14:43 +00003237- Limit free list of method and builtin function objects to 256
3238 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003239
Georg Brandl3ee81df2008-05-17 18:14:43 +00003240- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3241 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003242 to compact the internal free lists of pre-allocted ints and floats.
3243
Georg Brandl3ee81df2008-05-17 18:14:43 +00003244- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3245 calls. Python expected the return type int but the fork familie
3246 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003247
Georg Brandl3ee81df2008-05-17 18:14:43 +00003248- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3249 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003250
Georg Brandl3ee81df2008-05-17 18:14:43 +00003251- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3252 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3255 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003257- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3258 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003259
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260- Patch #1473257: generator objects gain a gi_code attribute. This is
3261 the same object as the func_code attribute of the function that
3262 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003263
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Issue #1920: "while 0" statements were completely removed by the
3265 compiler, even in the presence of an "else" clause, which is
3266 supposed to be run when the condition is false. Now the compiler
3267 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003268
Guido van Rossumeead05f2008-01-24 18:21:02 +00003269- A few crashers fixed: weakref_in_del.py (issue #1377858);
3270 loosing_dict_ref.py (issue #1303614, test67.py);
3271 borrowed_ref_[34].py (not in tracker).
3272
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003273- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003274 suppressed while an extension is loaded by calling SetErrorMode in
3275 dynload_win.c. The error is still reported properly.
3276
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003278 several extension methods and modules do not work without unicode
3279 support.
3280
Georg Brandl26543b12008-01-21 18:36:51 +00003281- Issue #1882: when compiling code from a string, encoding cookies in the
3282 second line of code were not always recognized correctly.
3283
Georg Brandl14404b62008-01-19 19:27:05 +00003284- Issue #1679: "0x" was taken as a valid integer literal.
3285
Georg Brandl6caad7d2008-01-26 14:19:22 +00003286- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003287 added.
3288
Christian Heimesc94e2b52008-01-14 04:13:37 +00003289- sys.float_info / PyFloat_GetInfo: The floating point information
3290 object was converted from a dict to a specialized structseq object.
3291
Georg Brandl3ee81df2008-05-17 18:14:43 +00003292- Patch #1816: Added sys.flags structseq. It exposes the status of
3293 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003294
Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Objects/structseq.c: Implemented new structseq representation. The
3296 patch makes structseqs (e.g. the return value of os.stat) more
3297 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003311- Improve some exception messages when Windows fails to load an
3312 extension module. Now we get for example '%1 is not a valid Win32
3313 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003320- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003321 and INF. float("nan"), float("inf") and float("-inf") now work on
3322 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003323
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Compiler now generates simpler and faster code for dictionary
3325 literals. The oparg for BUILD_MAP now indicates an estimated
3326 dictionary size. There is a new opcode, STORE_MAP, for adding
3327 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003356- Patch #1739468: Directories and zipfiles containing a __main__.py
3357 file can now be directly executed by passing their name to the
3358 interpreter. The directory/zipfile is automatically inserted as the
3359 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003360
Georg Brandl3ee81df2008-05-17 18:14:43 +00003361- Issue #1265: Fix a problem with sys.settrace, if the tracing
3362 function uses a generator expression when at the same time the
3363 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003364
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003365- sets and frozensets now have an isdisjoint() method.

3370
Georg Brandl3ee81df2008-05-17 18:14:43 +00003371- The enumerate() builtin function is no longer bounded to sequences
3372 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3373 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003374
Georg Brandl3ee81df2008-05-17 18:14:43 +00003375- Issue #1686386: Tuple's tp_repr did not take into account the
3376 possibility of having a self-referential tuple, which is possible
3377 from C code. Nor did object's tp_str consider that a type's tp_str
3378 could do something that could lead to an inifinite recursion.
3379 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3380 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003381
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382- Issue #1164: It was possible to trigger deadlock when using the
3383 'print' statement to write to a file since the GIL was not released
3384 as needed. Now PyObject_Print() does the right thing along with
3385 various tp_print implementations of the built-in types and those in
3386 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003387
Georg Brandl3ee81df2008-05-17 18:14:43 +00003388- Issue #1147: Exceptions were directly allowing string exceptions in
3389 their throw() method even though string exceptions no longer
3390 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003391
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392- Issue #1096: Prevent a segfault from getting the repr of a very
3393 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003394
Brett Cannon1e534b52007-09-07 04:18:30 +00003395- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003396 PyObject_Call() never calling back out to Python code to trigger
3397 recursion depth updates/checks. Required the creation of a static
3398 RuntimeError instance in case normalizing an exception put the
3399 recursion check value past its limit. Fixes crashers
3400 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003401

Neal Norwitz0ac60192007-05-27 04:08:54 +00003415- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003416 __*__ attributes. (Some already existed, e.g., __doc__ and
3417 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003418
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003419- Add -3 option to the interpreter to warn about features that are
3420 deprecated and will be changed/removed in Python 3.0.
3421
Georg Brandl2134e752007-05-21 20:34:16 +00003422- Patch #1686487: you can now pass any mapping after '**' in function
3423 calls.
3424
Collin Winter62903052007-05-18 23:11:24 +00003425- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003426 "except E as target:". This is to provide forwards compatibility
3427 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003428
Brett Cannon229cee22007-05-05 01:34:02 +00003429- Deprecate BaseException.message as per PEP 352.
3430
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003432 inherited from a builtin base.
3433
Vinay Sajip8549ce32007-05-06 17:53:37 +00003434- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003435 setting a plain string, ie don't expand to single letter identifiers.
3436
Raymond Hettinger13936692007-04-11 18:40:58 +00003437- Request #1191699: Slices can now be pickled.
3438
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003439- Request #1193128: str.translate() now allows a None argument for
3440 translations that only remove characters without re-mapping the
3441 remaining characters.
3442
Georg Brandl5cb76c12007-03-21 09:00:39 +00003443- Patch #1682205: a TypeError while unpacking an iterable is no longer

3445
Neal Norwitzaa754b72007-03-21 06:39:48 +00003446- Remove unused file Python/fmod.c.
3447
Guido van Rossum143b5642007-03-23 04:58:42 +00003448- Bug #1683368: The object.__init__() and object.__new__() methods are
3449 now stricter in rejecting excess arguments. The only time when
3450 either allows excess arguments is when it is not overridden and the
3451 other one is. For backwards compatibility, when both are
3452 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003453 warning later). Also, type.__init__() insists on the same signature
3454 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003455
Georg Brandl3ee81df2008-05-17 18:14:43 +00003456- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3457 object to complex using its __complex__() method before falling back
3458 to the __float__() method. Therefore, the functions in the cmath
3459 module now can operate on objects that define a __complex__()
3460 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003461
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Patch #1623563: allow __class__ assignment for classes with
3463 __slots__. The old and the new class are still required to have the
3464 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003465

3470 ``object.__reduce_ex__()`` is called with an object that is faking
3471 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003472
Georg Brandl3ee81df2008-05-17 18:14:43 +00003473- Patch #1680015: Don't modify __slots__ tuple if it contains an

3477
Georg Brandl7b9c5552007-03-12 14:30:05 +00003478- Bug #1678647: write a newline after printing an exception in any
3479 case, even when converting the value to a string failed.
3480
Georg Brandl871f1bc2007-03-12 13:17:36 +00003481- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482 its argument, if it exists. If not, it will work like before. This
3483 allows customizing the output of dir() in the presence of a
3484 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003485
Collin Winter276887b2007-03-12 16:11:39 +00003486- Patch #922167: Python no longer segfaults when faced with infinitely
3487 self-recursive reload() calls (as reported by bug #742342).
3488

Georg Brandl3ee81df2008-05-17 18:14:43 +00003492- Patch #1491866: change the complex() constructor to allow
3493 parthensized forms. This means complex(repr(x)) now works instead of
3494 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003495
Georg Brandlaa2321b2007-03-07 00:40:28 +00003496- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497 makes the filenames the warning module prints much more sensible
3498 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003499
Georg Brandl49aafc92007-03-07 00:34:46 +00003500- Variant of patch #697613: don't exit the interpreter on a SystemExit
3501 exception if the -i command line option or PYTHONINSPECT environment

Georg Brandl0fca97a2007-03-05 22:28:08 +00003511- Patch #1674228: when assigning a slice (old-style), check for the
3512 sq_ass_slice instead of the sq_slice slot.
3513
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514- When printing an unraisable error, don't print exceptions. before
3515 the name. This duplicates the behavior whening normally printing
3516 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003517
Georg Brandl3ee81df2008-05-17 18:14:43 +00003518- Bug #1653736: Properly discard third argument to

3573
Armin Rigo7ccbca92006-10-04 12:17:45 +00003574- A number of places, including integer negation and absolute value,

4144 -- the failure just occurred later, with a more cumbersome
4145 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004426- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4427 with RFC 3207 and forgets any knowledge obtained from the server not
4428 obtained from the TLS negotiation itself. Patch contributed by Bill
4429 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004430
Georg Brandl3ee81df2008-05-17 18:14:43 +00004431- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004432 that the SMTP.starttls() caller no longer needs to call ehlo()
4433 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004434 does not claim to support starttls. Adds the
4435 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4436 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004490- itertools.chain() now has an alternate constructor,

4516 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4517 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004519

Georg Brandl3ee81df2008-05-17 18:14:43 +00004534 time so that opening a database previously created with the DB_DUP
4535 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4536 opens. Specifically: dictionary assignment to a DB object will
4537 replace all values for a given key when the database allows
4538 duplicate values. DB users should use DB.put(k, v) when they want
4539 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004540

4546 characters with ASCII value less than 32. Also, it correctly quotes
4547 dots only if they occur on a single line, as opposed to the previous
4548 behavior of quoting dots if they are the second character of any
4549 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004550

4820 default, this option is turned-off. It should only be enabled in
4821 debugged, performance critical applications.

4872-----
4873
Georg Brandl3ee81df2008-05-17 18:14:43 +00004874- Unified naming convention for free lists and their limits. All free
4875 lists in Object/ are named ``free_list``, the counter ``numfree``
4876 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4877 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004878
Georg Brandl3ee81df2008-05-17 18:14:43 +00004879- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4880 to ``PyTuple_SetItem``, it can be used to populate a brand new
4881 frozenset; but it does not steal a reference to the added item.

4893
Georg Brandl3ee81df2008-05-17 18:14:43 +00004894- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4895 of w# format code incorrectly truncated the length to an int, even
4896 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4897 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004898
Georg Brandl3ee81df2008-05-17 18:14:43 +00004899- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4917- Fix some leftovers from the conversion from int to Py_ssize_t
4918 (relevant to strings and sequences of more than 2**31 items).
4919
4920- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4921 outside of pystate.c and should not be necessary.
4922
Georg Brandl3ee81df2008-05-17 18:14:43 +00004923- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4924 absolute imports. In earlier versions they might have used relative
4925 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004926
Georg Brandl3ee81df2008-05-17 18:14:43 +00004927- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4928 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004929
Georg Brandl3ee81df2008-05-17 18:14:43 +00004930- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4938 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4939 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4940 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004941

Georg Brandl3ee81df2008-05-17 18:14:43 +00004955- Removed the macfs module. It had been deprecated since Python 2.5.
4956 This lead to the deprecation of macostools.touched() as it relied
4957 solely on macfs and was a no-op under OS X.
