Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000067- Issue #7419: setlocale() could crash the interpreter on Windows when called
68 with invalid values.
69
Eric Smithc4ab8332009-11-29 17:40:57 +000070- Issue #3382: 'F' formatting for float and complex now convert the
71 result to upper case. This only affects 'inf' and 'nan', since 'f'
72 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000073
Mark Dickinson9dd5e162009-11-23 20:54:09 +000074- Remove switch from "%f" formatting to "%g" formatting for floats
75 larger than 1e50 in absolute value.
76
Mark Dickinson18cfada2009-11-23 18:46:41 +000077- Remove restrictions on precision when formatting floats. E.g.,
78 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
79 requested 120 significant digits instead.
80
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000081- Add Py3k warnings for parameter names in parenthesis.
82
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000083- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000084
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000085- Issue #7085: Fix crash when importing some extensions in a thread
86 on MacOSX 10.6.
87
Mark Dickinsonb678de82009-11-19 18:41:49 +000088- Issue #7117: repr(x) for a float x returns a result based on the
89 shortest decimal string that's guaranteed to round back to x under
90 correct rounding (with round-half-to-even rounding mode).
91 Previously it gave a string based on rounding x to 17 decimal digits.
92 repr(x) for a complex number behaves similarly. On platforms where
93 the correctly-rounded strtod and dtoa code is not supported (see below),
94 repr is unchanged.
95
96- Issue #7117: On almost all platforms: float-to-string and
97 string-to-float conversions within Python are now correctly rounded.
98 Places these conversions occur include: str for floats and complex
99 numbers; the float and complex constructors; old-style and new-style
100 numeric formatting; serialization and deserialization of floats and
101 complex numbers using marshal, pickle and json; parsing of float and
102 imaginary literals in Python code; Decimal-to-float conversion.
103
104 The conversions use a Python-adapted version of David Gay's
105 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
106 functions. This code is supported on Windows, and on Unix-like
107 platforms using gcc, icc or suncc as the C compiler. There may be a
108 small number of platforms on which correct operation of this code
109 cannot be guaranteed, so the code is not used: notably, this applies
110 to platforms where the C double format is not IEEE 754 binary64, and
111 to platforms on x86 hardware where the x87 FPU is set to 64-bit
112 precision and Python's configure script is unable to determine how
113 to change the FPU precision. On these platforms conversions use the
114 platform strtod and dtoa, as before.
115
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000116- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000117 now uses the correctly-rounded string <-> float conversions
118 described above (when available), and so produces correctly rounded
119 results that will display nicely under the float repr. There are
120 two related small changes: (1) round now accepts any class with an
121 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000122 floats for the second argument), and (2) an excessively large second
123 integer argument (e.g., round(1.234, 10**100)) no longer raises an
124 exception.
125
Philip Jenveyfab8be22009-11-17 02:42:26 +0000126- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
127
Benjamin Petersone36199b2009-11-12 23:39:44 +0000128- Fix several issues with compile(). The input can now contain Windows and Mac
129 newlines and is no longer required to end in a newline.
130
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000131- Remove length limitation when constructing a complex number from a
132 unicode string.
133
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000134- Issue #7244: itertools.izip_longest() no longer ignores exceptions
135 raised during the formation of an output tuple.
136

141 interpreter is killed. Patch by Adam Olsen.
142
Eric Smithc12781a2009-10-19 14:38:14 +0000143- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

Eric Smitha985a3a2009-05-05 18:26:08 +0000272- Issue #5920: For float.__format__, change the behavior with the
273 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
274 to be like 'g' but with at least one decimal point and with a
275 default precision of 12. Previously, the behavior the same but with
276 a default precision of 6. This more closely matches str(), and
277 reduces surprises when adding alignment flags to the empty
278 presentation type. This also affects the new complex.__format__ in
279 the same way.
280
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000281- Issue #5890: in subclasses of 'property' the __doc__ attribute was

309 floats, ints, and longs.
310
311- Issue #5515: 'n' formatting for ints, longs, and floats handles
312 leading zero formatting poorly.
313
314- Issue #5772: For float.__format__, don't add a trailing ".0" if
315 we're using no type code and we have an exponent.
316
Mark Dickinson6736cf82009-04-20 21:13:33 +0000317- Issue #3166: Make long -> float (and int -> float) conversions
318 correctly rounded.

321 some builtin types.
322
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000323- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000324 was giving 5e15+2; round(-0.0) was losing the sign of the zero.

329
R. David Murray0374a822009-04-09 21:54:50 +0000330- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
331 its clarity and its speed.
332
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000333- Issue #2396: the memoryview object was backported from Python 3.1.

339
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000340- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
341 the end sys.path, for compatibility with the system install of Python.
342
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000343- Issue #4688: Add a heuristic so that tuples and dicts containing only
344 untrackable objects are not tracked by the garbage collector. This can
345 reduce the size of collections and therefore the garbage collection overhead
346 on long-running programs, depending on their particular use of datatypes.
347
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000348- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
349 improve its performance. Long divisions and remainder operations
350 are now between 50% and 150% faster.
351
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000352- Issue #4258: Make it possible to use base 2**30 instead of base
353 2**15 for the internal representation of integers, for performance
354 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
355 --enable-big-digits option to configure, which overrides the
356 default. Add sys.long_info structseq to provide information about
357 the internal format.
358
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000359- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
360 result traceback.__members__ no longer exists.)
361
Mark Dickinson6b265f12009-03-18 16:07:26 +0000362- Issue #4474: PyUnicode_FromWideChar now converts characters outside
363 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
364 and sizeof(Py_UNICODE) == 2.
365
Eric Smith6f42edb2009-03-14 11:57:26 +0000366- Issue #5237: Allow auto-numbered fields in str.format(). For
367 example: '{} {}'.format(1, 2) == '1 2'.
368
Brett Cannon6c4cff02009-03-11 04:51:06 +0000369- Issue #3652: Make the 'line' argument for warnings.showwarning() a
370 requirement. Means the DeprecationWarning from Python 2.6 can go away.
371
Eric Smithe9fb6862009-02-20 14:02:36 +0000372- Issue #5247: Improve error message when unknown format codes are
373 used when using str.format() with str, unicode, long, int, and
374 float arguments.
375
Raymond Hettinger08259e82009-02-18 23:10:19 +0000376- Running Python with the -3 option now also warns about classic division
377 for ints and longs.
378
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000379- Issue #5260: Long integers now consume less memory: average
380 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
381 on a 64-bit system.
382
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000383- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
384 rotating the object pointer by 4 bits to the right.
385
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000386- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
387 it now forces its argument to double before testing for infinity.
388
Benjamin Petersone18ef192009-01-20 14:21:16 +0000389- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
390
Georg Brandl29c6a282009-04-05 20:23:13 +0000391- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000392 were suppressing all exceptions. These include list(), filter(), map(),
393 zip(), and bytearray().
394
Benjamin Peterson596d3062009-01-19 15:42:23 +0000395- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
396 functions.
397
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000398- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
399 OSError.

Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +0000401- Issue #4807: Port the _winreg module to Windows CE.
402
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000403- Issue #4935: The overflow checking code in the expandtabs() method common
404 to str, bytes and bytearray could be optimized away by the compiler, letting
405 the interpreter segfault instead of raising an error.
406
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000407- Issue #3720: Fix a crash when an iterator modifies its class and removes its
408 __next__ method.
409
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000410- Issue #4893: Use NT threading on CE.

413
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000414- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
415 collecting the oldest generation) so that allocating lots of objects without
416 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000417 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000418 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

421
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000422- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
423 an existing .py counterpart, override the co_filename attributes of all
424 code objects if the original filename is obsolete (which can happen if the
425 file has been renamed, moved, or if it is accessed through different paths).
426 Patch by Ziga Seilnacht and Jean-Paul Calderone.
427
Martin v. Löwis5344c992009-01-02 20:32:55 +0000428- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000430- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
431 file with `str' filename on Windows.
432
Antoine Pitrouaa687902009-01-01 14:11:22 +0000433- Issue #3680: Reference cycles created through a dict, set or deque iterator
434 did not get collected.
435
Nick Coghlan180e4002008-12-30 01:18:48 +0000436- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
437 where the tp_hash and tp_dict slots are both NULL.
438
Benjamin Peterson7af65562008-12-29 17:56:58 +0000439- Issue #4764: With io.open, IOError.filename is set when trying to open a
440 directory on POSIX systems.
441
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000442- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
443 systems.
444
Georg Brandl6425a2f2008-12-28 11:54:53 +0000445- Issue #4759: None is now allowed as the first argument of
446 bytearray.translate(). It was always allowed for bytes.translate().
447
Skip Montanarof205c132008-12-23 03:30:15 +0000448- Added test case to ensure attempts to read from a file opened for writing
449 fail.
450
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000451- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
452 print elapsed times, not only when some objects are uncollectable /
453 unreachable. Original patch by Neil Schemenauer.
454
Mark Dickinson1a707982008-12-17 16:14:37 +0000455- Issue #3439: Add a bit_length method to int and long.

Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000460- Issue #4597: Fixed exception handling when the __exit__ function of a
461 context manager returns a value that cannot be converted to a bool.
462
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000463- Issue #4597: Fixed several opcodes that weren't always propagating
464 exceptions.
465
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000466- Issue #4445: Replace "sizeof(PyStringObject)" with
467 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
468 str instances. On a typical machine this saves 3 bytes of memory
469 (on average) per string allocation.
470
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000471- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
472 interpreter to abort ("Fatal Python error: Could not reset the stack!")
473 instead of throwing a MemoryError.
474
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000475- Issue #3689: The list reversed iterator now supports __length_hint__
476 instead of __len__. Behavior now matches other reversed iterators.
477
Benjamin Petersonc078f922008-11-21 22:27:24 +0000478- Issue #4367: Python would segfault during compiling when the unicodedata
479 module couldn't be imported and \N escapes were present.
480
Vinay Sajip213faca2008-12-03 23:22:58 +0000481- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000482 method on file objects with closefd=False. The file descriptor is still
483 kept open but the file object behaves like a closed file. The ``FileIO``
484 object also got a new readonly attribute ``closefd``.
485
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000486- Issue #4348: Some bytearray methods returned that didn't cause any change to
487 the bytearray, returned the same bytearray instead of a copy.
488
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000489- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

494
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000495- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
496 exec statement.
497
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000498- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
499 method does not return iterators for the 4th and 5th items.
500
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000501- Issue #4209: Enabling unicode_literals and the print_function in the same
502 __future__ import didn't work.
503
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000504- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000505 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000506
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000507- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
508 returned a path longer than MAX_PATH. (But It's doubtful this code path is
509 really executed because I cannot move to such directory on win2k)
510
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000511- Issue #4069: When set.remove(element) is used with a set element, the element
512 is temporarily replaced with an equivalent frozenset. But the eventual
513 KeyError would always report the empty frozenset([]) as the missing key. Now
514 it correctly refers to the initial element.
515
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000516- Issue #4509: Various issues surrounding resize of bytearray objects to
517 which there are buffer exports.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000531- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
532 returned them on 64bit platforms.
533
Walter Dörwalded960ac2009-05-03 22:36:33 +0000534- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
535 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
536 step. This avoids problems with counting UTF-8 bytes that ignores the effect
537 of using the replace error handler in PyUnicode_DecodeUTF8().
538
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000539- Issue #3739: The unicode-internal encoder now reports the number of characters
540 consumed like any other encoder (instead of the number of bytes).
541
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000542- Issue #2422: When compiled with the ``--with-valgrind`` option, the
543 pymalloc allocator will be automatically disabled when running under
544 Valgrind. This gives improved memory leak detection when running
545 under Valgrind, while taking advantage of pymalloc at other times.

1722 - Packing a float now always gives a Deprecation Warning.
1723 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1724
1725 - If x is not an int, long or float, then packing x will always
1726 result in struct.error. Previously an x with an __int__ method
1727 could be packed by 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h'
1728 ,'*i', '*l', and an x with a __long__ method could be packed by
1729 'q', 'Q', '*q', '*Q'; for x with neither __int__ nor __long__,
1730 TypeError used to be raised (with a confusing error message) for
1731 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001925- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1926 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1927 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1928 ``printf`` function, whereas PyString_FromFormat has an independent
1929 implementation and uses "%zd" on all platforms for size_t values.
1930 This makes a difference on win64, where ``printf`` needs "%Id" to display
1931 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001951 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1952 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1953 when given a tuple of classes as second argument, were looking up
1954 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1955 type object.

2026 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2027 for catch_warnings() also led to an improvement in the raising of a
2028 DeprecationWarning related to warnings.warn_explicit().

2052
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002053- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002094What's New in Python 2.6 beta 3?
2095================================
2096
Barry Warsaw07a4a382008-08-21 01:15:08 +00002097*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002098
2099Core and Builtins
2100-----------------
2101
Guido van Rossumf8402962008-08-20 15:01:50 +00002102- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2103 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2104 extensions do not automatically benefit from the class attribute
2105 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2106 to their tp_flags field if they care. This is a backwards
2107 compatibility feature; in 3.0, all types will use the cache by
2108 default.
2109
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002110- Keyword arguments can now follow starred arguments. (``f(a, *args,
2111 keyword=23)`` is now valid syntax.)
2112
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002113- ctypes function pointers that are COM methods have a boolean True
2114 value again.
2115
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002116- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2117 by denying s# to parse objects that have a releasebuffer procedure,
2118 and introducing s*.
2119
Georg Brandl1e13ea92008-08-11 09:07:59 +00002120- Issue #3537: Fix an assertion failure when an empty but presized dict
2121 object was stored in the freelist.
2122
Mark Dickinsonb6467572008-08-04 21:30:09 +00002123- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2124 ValueError consistently across platforms.
2125
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002126- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2127 (64bit Unix, for example), unichr() would truncate its argument and return
2128 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2129
Neal Norwitze7d8be82008-07-31 17:17:14 +00002130- Apply security patches from Apple.
2131
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002132- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2133 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2134
Antoine Pitrou92f82162008-07-25 22:22:08 +00002135- Issue #1819: function calls with several named parameters are now on
2136 average 35% faster (as measured by pybench).
2137
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002138- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2139 the python debugger steps into a class statement: the free variables (local
2140 variables defined in an outer scope) would be deleted from the outer scope.
2141
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002142- Issue #2620: Overflow checking when allocating or reallocating memory
2143 was not always being done properly in some python types and extension
2144 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2145 all been updated to perform better checks and places in the code that
2146 would previously leak memory on the error path when such an allocation
2147 failed have been fixed.

2155 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2156
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002157- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2158 version reported by these tools does not necessarily follow the python
2159 version numbering scheme, so the module is less strict when parsing it.
2160
Nick Coghlanf70385a2008-08-18 12:42:46 +00002161- Issue #2235: Added Py3k warnings for types which will become unhashable
2162 under the stricter __hash__ inheritance rules in 3.0. Several types
2163 which did not meet the rules for hash invariants and were already
2164 unhashable in 3.0 have now been explicitly flagged as unhashable in
2165 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2166 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2167
Brett Cannon88f801d2008-08-18 00:46:22 +00002168- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2176
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002177- Issue #3575: Incremental decoder's decode function now takes bytearray
2178 by using 's*' instead of 't#'.
2179
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002180- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002181 fails unicode conversion on 2nd parameter. (windows only)
2182
Facundo Batista94f243a2008-08-17 03:38:39 +00002183- Issue 2464. urllib2 now supports a malformation in the URL received
2184 in a redirect.
2185

Brett Cannon721b1452008-08-16 22:00:27 +00002187 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002188
Facundo Batistaeb90b782008-08-16 14:44:07 +00002189- Issue #2776: fixed small issue when handling an URL with double slash
2190 after a 302 response in the case of not going through a proxy.
2191
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002192- Issue #2676: in the email package, content-type parsing was hanging on
2193 pathological input because of quadratic or exponential behaviour of a
2194 regular expression.
2195
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002196- Issue #3476: binary buffered reading through the new "io" library is now
2197 thread-safe.
2198
Brett Cannonbf3157b2008-08-14 05:00:03 +00002199- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2200 since mimetools itself is deprecated. Because modules are cached, all
2201 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2202
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002203- Issue #3134: shutil referenced undefined WindowsError symbol.
2204
Robert Schuppenies14646332008-08-10 11:01:53 +00002205- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2206 menu entries were not deleted.
2207
Brett Cannon83e81842008-08-09 23:30:55 +00002208- Copied the implementation of reduce() to _functools.reduce() to have a
2209 version that did not raise a DeprecationWarning under -3.
2210
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002211- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2212 a MemoryError rather than silently stop the iteration.
2213
Guido van Rossum59ce9012008-08-09 14:55:34 +00002214- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2215 to _sre.compile() will now be rejected. This should not affect anybody
2216 since the re.compile() function never generates invalid re-bytecode.
2217
Skip Montanaroa032bf42008-08-08 22:52:51 +00002218- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00002237 asking for a specific length. This problem only affected files opened
2238 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002239

2265 mode 0600 rather than 000 under Unix.
2266
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002267- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002288What's New in Python 2.6 beta 2?
2289================================
2290
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002291*Release date: 17-Jul-2008*
2292
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002293Core and Builtins
2294-----------------
2295
Georg Brandl3e483f62008-07-16 22:57:41 +00002296- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2297 its methods now allow for items objects that can be converted to
2298 an integer using operator.index().
2299
Mark Dickinson64b7e502008-07-16 09:40:03 +00002300- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2301 produced a ValueError instead of giving the correct float.
2302
Eric Smitha5fa5a22008-07-16 00:11:49 +00002303- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2304 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2305
Mark Dickinson7103aa42008-07-15 19:08:33 +00002306- Issue #3008: the float type has a new instance method 'float.hex'
2307 and a new class method 'float.fromhex' to convert floating-point
2308 numbers to and from hexadecimal strings, respectively.
2309
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002310- Issue #2235: __hash__ is once again inherited by default. To allow
2311 collections.Hashable to remain meaningful in the presence of the
2312 default hash implementation (object.__hash__), it is now possible
2313 to explicit block inheritance of hash by setting __hash__=None at
2314 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2315 level.
2316
Nick Coghlanb028f502008-07-13 14:52:36 +00002317- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2318 the parent module cannot be found while performing an absolute import.
2319 This means that an incorrectly defined __package__ attribute will
2320 now only prevent relative imports in that module rather than causing
2321 all imports from that module to fail.
2322
Nick Coghlan14ff9942008-07-08 14:21:42 +00002323- Issue #2517: Allow unicode messages in Exceptions again by correctly
2324 bypassing the instance dictionary when looking up __unicode__ on
2325 new-style classes.
2326
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002327- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2328 set to a custom object whose write() method happens to install
2329 another file in sys.stdout.
2330
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002331- Issue #3088: Corrected a race condition in classes derived from
2332 threading.local: the first member set by a thread could be saved in
2333 another thread's dictionary.
2334
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002335- Issue #3004: Minor change to slice.indices(): the start and stop
2336 arguments are now treated identically, making the behaviour easier
2337 to describe and understand. For example, slice(None, -10,
2338 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2339 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2340 10, -1).
2341
Georg Brandl278fc502008-07-19 12:46:12 +00002342- Issue #3219: Calling a function with repeated keyword arguments,
2343 f(a=2, a=23), would not cause a syntax error. This was a regression
2344 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002345
Georg Brandl278fc502008-07-19 12:46:12 +00002346- Issue #2862: Make int and float freelist management consistent with
2347 other freelists. Changes their CompactFreeList apis into
2348 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002349
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002350Library
2351-------
2352
Thomas Heller57adf222008-08-14 19:10:48 +00002353- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2354 api functions without holding the GIL, which could lead to a fatal
2355 error when they failed.
2356
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002357- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
2358

2364
Jesse Noller13e9d582008-07-16 14:32:36 +00002365- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2366 ForkingPickler.register() to resolve conflict with ctypes.
2367
Vinay Sajip51e65192008-07-18 09:01:10 +00002368- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002369
Thomas Heller880f5292008-07-15 19:39:38 +00002370- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2371 a valid dlerror() message.
2372
Thomas Heller2bad6572008-07-15 17:19:50 +00002373- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2374 incomplete structure was created.
2375

2377
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002378- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2379
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002380- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002381
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002382- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2383 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002384 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002385 content-length. The problem had been corrected in the 2.4 branch, but never
2386 merged into trunk.
2387
Georg Brandle78fbcc2008-07-05 10:13:36 +00002388- Issue #2663: add filtering capability to shutil.copytree().

2393
2394- Issue #1746: Correct handling of zipfile archive comments (previously
2395 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002396 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002397
Vinay Sajip51e65192008-07-18 09:01:10 +00002398- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002399 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002400
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002401- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2402 handling is now the same as that of other special attributes like __name__).
2403
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002404- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Issue #1631171: Re-implement the 'warnings' module in C (the
2857 original Python code has been kept as backup). This will allow for
2858 using the 'warning's machinery in such places as the parser where
2859 use of pure Python code is not possible. Both the ``showarning()``
2860 and ``formatwarning()`` gain an optional 'line' argument which is
2861 not called by default for backwards-compatibility reasons. Setting
2862 ``warnings.showwarning()`` to an implementation that lacks support
2863 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002926- Issue #2550: The approach used by client/server code for obtaining
2927 ports to listen on in network-oriented tests has been refined in an
2928 effort to facilitate running multiple instances of the entire
2929 regression test suite in parallel without issue.
2930 test_support.bind_port() has been fixed such that it will always
2931 return a unique port -- which wasn't always the case with the
2932 previous implementation, especially if socket options had been set
2933 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2934 new implementation of bind_port() will actually raise an exception
2935 if it is passed an AF_INET/SOCK_STREAM socket with either the
2936 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2937 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2938 the socket it's been passed. This currently only applies to
2939 Windows. This option prevents any other sockets from binding to the
2940 host/port we've bound to, thus removing the possibility of the
2941 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2942 when a second SOCK_STREAM socket binds and accepts to a host/port
2943 that's already been bound by another socket. The optional preferred
2944 port parameter to bind_port() has been removed. Under no
2945 circumstances should tests be hard coding ports!
2946
2947 test_support.find_unused_port() has also been introduced, which will
2948 pass a temporary socket object to bind_port() in order to obtain an
2949 unused port. The temporary socket object is then closed and
2950 deleted, and the port is returned. This method should only be used
2951 for obtaining an unused port in order to pass to an external program
2952 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2953 a parameter to a server-oriented class that doesn't give you direct
2954 access to the underlying socket used.
2955
2956 Finally, test_support.HOST has been introduced, which should be used
2957 for the host argument of any relevant socket calls (i.e. bind and
2958 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002959
2960 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002961 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002962 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2963 test_asynchat and test_socket_ssl.
2964
Georg Brandl3ee81df2008-05-17 18:14:43 +00002965 It is now possible for multiple instances of the regression test
2966 suite to run in parallel without issue.

3122 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00003123 platform.machine() and platform.processor() will report this
3124 information as well.

3232Core and builtins
3233-----------------
3234
Fred Drakea8ee94b2008-03-01 02:45:07 +00003235- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003236 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003237
Georg Brandlad61bc82008-02-23 15:11:18 +00003238- Issue #2067: file.__exit__() now calls subclasses' close() method.
3239
3240- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003241
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003242- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003243 issue 215555 for a discussion.
3244
Eric Smitha73fbe72008-02-23 03:09:44 +00003245- Added the future_builtins module, which contains hex() and oct().
3246 These are the PEP 3127 version of these functions, designed to be
3247 compatible with the hex() and oct() builtins from Python 3.0. They
3248 differ slightly in their output formats from the existing, unchanged
3249 Python 2.6 builtins. The expected usage of the future_builtins
3250 module is:
3251 from future_builtins import hex, oct
3252
Eric Smith7ef40bf2008-02-20 23:34:22 +00003253- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3254 exponents for exponents with absolute value < 100. Follows C99
3255 standard. This is a change on Windows, which would use 3 digits.
3256 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3257 so that any alterations it does to the resulting string will be
3258 available in stringlib/formatter.h (for float.__format__).
3259
Eric Smith5a3c1352008-02-19 13:21:56 +00003260- Implemented PEP 3101, Advanced String Formatting. This adds a new
3261 builtin format(); a format() method for str and unicode; a
3262 __format__() method to object, str, unicode, int, long, float, and
3263 datetime; the class string.Formatter; and the C API
3264 PyObject_Format().
3265
Georg Brandl3ee81df2008-05-17 18:14:43 +00003266- Fixed several potential crashes, all caused by specially crafted
3267 __del__ methods exploiting objects in temporarily inconsistent
3268 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003269
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003270- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003271 prevent a possible crash: an Abstract Base Class would try to access
3272 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003273
Georg Brandl3ee81df2008-05-17 18:14:43 +00003274- Fixed repr() and str() of complex numbers with infinity or nan as
3275 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Clear all free lists during a gc.collect() of the highest generation
3278 in order to allow pymalloc to free more arenas. Python may give back
3279 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003280
Georg Brandl3ee81df2008-05-17 18:14:43 +00003281- Issue #2045: Fix an infinite recursion triggered when printing a
3282 subclass of collections.defaultdict, if its default_factory is set
3283 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003284
Christian Heimesf75dbef2008-02-08 00:11:31 +00003285- Fixed a minor memory leak in dictobject.c. The content of the free
3286 list was not freed on interpreter shutdown.
3287
Georg Brandl3ee81df2008-05-17 18:14:43 +00003288- Limit free list of method and builtin function objects to 256
3289 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003290
Georg Brandl3ee81df2008-05-17 18:14:43 +00003291- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3292 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003293 to compact the internal free lists of pre-allocted ints and floats.
3294
Georg Brandl3ee81df2008-05-17 18:14:43 +00003295- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3296 calls. Python expected the return type int but the fork familie
3297 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003298
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3300 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003308- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3309 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003310
Georg Brandl3ee81df2008-05-17 18:14:43 +00003311- Patch #1473257: generator objects gain a gi_code attribute. This is
3312 the same object as the func_code attribute of the function that
3313 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003314
Georg Brandl3ee81df2008-05-17 18:14:43 +00003315- Issue #1920: "while 0" statements were completely removed by the
3316 compiler, even in the presence of an "else" clause, which is
3317 supposed to be run when the condition is false. Now the compiler
3318 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003319
Guido van Rossumeead05f2008-01-24 18:21:02 +00003320- A few crashers fixed: weakref_in_del.py (issue #1377858);
3321 loosing_dict_ref.py (issue #1303614, test67.py);
3322 borrowed_ref_[34].py (not in tracker).
3323
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003324- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003325 suppressed while an extension is loaded by calling SetErrorMode in
3326 dynload_win.c. The error is still reported properly.
3327
Georg Brandl3ee81df2008-05-17 18:14:43 +00003328- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003329 several extension methods and modules do not work without unicode
3330 support.
3331
Georg Brandl26543b12008-01-21 18:36:51 +00003332- Issue #1882: when compiling code from a string, encoding cookies in the
3333 second line of code were not always recognized correctly.
3334
Georg Brandl14404b62008-01-19 19:27:05 +00003335- Issue #1679: "0x" was taken as a valid integer literal.
3336
Georg Brandl6caad7d2008-01-26 14:19:22 +00003337- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003338 added.
3339
Christian Heimesc94e2b52008-01-14 04:13:37 +00003340- sys.float_info / PyFloat_GetInfo: The floating point information
3341 object was converted from a dict to a specialized structseq object.
3342
Georg Brandl3ee81df2008-05-17 18:14:43 +00003343- Patch #1816: Added sys.flags structseq. It exposes the status of
3344 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003345
Georg Brandl3ee81df2008-05-17 18:14:43 +00003346- Objects/structseq.c: Implemented new structseq representation. The
3347 patch makes structseqs (e.g. the return value of os.stat) more
3348 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003349
Georg Brandl3ee81df2008-05-17 18:14:43 +00003350- Patch #1700288: added a type attribute cache that caches method
3351 accesses, resulting in speedups in heavily object-oriented code.

3359 envvar and sys.dont_write_bytecode attribute. All these can be set
3360 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003361
Georg Brandl3ee81df2008-05-17 18:14:43 +00003362- Improve some exception messages when Windows fails to load an
3363 extension module. Now we get for example '%1 is not a valid Win32
3364 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003365

Christian Heimes0a8143f2007-12-18 23:22:54 +00003371- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003372 and INF. float("nan"), float("inf") and float("-inf") now work on
3373 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003374
Georg Brandl3ee81df2008-05-17 18:14:43 +00003375- Compiler now generates simpler and faster code for dictionary
3376 literals. The oparg for BUILD_MAP now indicates an estimated
3377 dictionary size. There is a new opcode, STORE_MAP, for adding
3378 entries to the dictionary.

3396 running, and if the deallocation of its frames somehow calls the
3397 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003398

Georg Brandl3ee81df2008-05-17 18:14:43 +00003407- Patch #1739468: Directories and zipfiles containing a __main__.py
3408 file can now be directly executed by passing their name to the
3409 interpreter. The directory/zipfile is automatically inserted as the
3410 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003411
Georg Brandl3ee81df2008-05-17 18:14:43 +00003412- Issue #1265: Fix a problem with sys.settrace, if the tracing
3413 function uses a generator expression when at the same time the
3414 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003415
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003416- sets and frozensets now have an isdisjoint() method.
3417

3421
Georg Brandl3ee81df2008-05-17 18:14:43 +00003422- The enumerate() builtin function is no longer bounded to sequences
3423 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3424 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003425
Georg Brandl3ee81df2008-05-17 18:14:43 +00003426- Issue #1686386: Tuple's tp_repr did not take into account the
3427 possibility of having a self-referential tuple, which is possible
3428 from C code. Nor did object's tp_str consider that a type's tp_str
3429 could do something that could lead to an inifinite recursion.
3430 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3431 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003432
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Issue #1164: It was possible to trigger deadlock when using the
3434 'print' statement to write to a file since the GIL was not released
3435 as needed. Now PyObject_Print() does the right thing along with
3436 various tp_print implementations of the built-in types and those in
3437 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003438
Georg Brandl3ee81df2008-05-17 18:14:43 +00003439- Issue #1147: Exceptions were directly allowing string exceptions in
3440 their throw() method even though string exceptions no longer
3441 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003442
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443- Issue #1096: Prevent a segfault from getting the repr of a very
3444 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003445
Brett Cannon1e534b52007-09-07 04:18:30 +00003446- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003447 PyObject_Call() never calling back out to Python code to trigger
3448 recursion depth updates/checks. Required the creation of a static
3449 RuntimeError instance in case normalizing an exception put the
3450 recursion check value past its limit. Fixes crashers
3451 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003452
Georg Brandl3ee81df2008-05-17 18:14:43 +00003453- Patch #1031213: Decode source line in SyntaxErrors back to its

3457 with %G.
3458
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00003466- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003467 __*__ attributes. (Some already existed, e.g., __doc__ and
3468 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003469
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003470- Add -3 option to the interpreter to warn about features that are
3471 deprecated and will be changed/removed in Python 3.0.
3472
Georg Brandl2134e752007-05-21 20:34:16 +00003473- Patch #1686487: you can now pass any mapping after '**' in function
3474 calls.
3475
Collin Winter62903052007-05-18 23:11:24 +00003476- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003477 "except E as target:". This is to provide forwards compatibility
3478 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003479
Brett Cannon229cee22007-05-05 01:34:02 +00003480- Deprecate BaseException.message as per PEP 352.
3481
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003483 inherited from a builtin base.
3484
Vinay Sajip8549ce32007-05-06 17:53:37 +00003485- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003486 setting a plain string, ie don't expand to single letter identifiers.
3487
Raymond Hettinger13936692007-04-11 18:40:58 +00003488- Request #1191699: Slices can now be pickled.
3489
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003490- Request #1193128: str.translate() now allows a None argument for
3491 translations that only remove characters without re-mapping the
3492 remaining characters.
3493
Georg Brandl5cb76c12007-03-21 09:00:39 +00003494- Patch #1682205: a TypeError while unpacking an iterable is no longer
3495 masked by a generic one with the message "unpack non-sequence".
3496
Neal Norwitzaa754b72007-03-21 06:39:48 +00003497- Remove unused file Python/fmod.c.
3498
Guido van Rossum143b5642007-03-23 04:58:42 +00003499- Bug #1683368: The object.__init__() and object.__new__() methods are
3500 now stricter in rejecting excess arguments. The only time when
3501 either allows excess arguments is when it is not overridden and the
3502 other one is. For backwards compatibility, when both are
3503 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003504 warning later). Also, type.__init__() insists on the same signature
3505 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003506
Georg Brandl3ee81df2008-05-17 18:14:43 +00003507- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3508 object to complex using its __complex__() method before falling back
3509 to the __float__() method. Therefore, the functions in the cmath
3510 module now can operate on objects that define a __complex__()
3511 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003512
Georg Brandl3ee81df2008-05-17 18:14:43 +00003513- Patch #1623563: allow __class__ assignment for classes with
3514 __slots__. The old and the new class are still required to have the
3515 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003516
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Patch #1462488: Python no longer segfaults when
3521 ``object.__reduce_ex__()`` is called with an object that is faking
3522 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003523
Georg Brandl3ee81df2008-05-17 18:14:43 +00003524- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003527- Patch #1444529: the builtin compile() now accepts keyword arguments.
3528
Georg Brandl7b9c5552007-03-12 14:30:05 +00003529- Bug #1678647: write a newline after printing an exception in any
3530 case, even when converting the value to a string failed.
3531
Georg Brandl871f1bc2007-03-12 13:17:36 +00003532- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003533 its argument, if it exists. If not, it will work like before. This
3534 allows customizing the output of dir() in the presence of a
3535 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003536
Collin Winter276887b2007-03-12 16:11:39 +00003537- Patch #922167: Python no longer segfaults when faced with infinitely
3538 self-recursive reload() calls (as reported by bug #742342).
3539
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540- Patch #1675981: remove unreachable code from ``type.__new__()``
3541 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003543- Patch #1491866: change the complex() constructor to allow
3544 parthensized forms. This means complex(repr(x)) now works instead of
3545 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003546
Georg Brandlaa2321b2007-03-07 00:40:28 +00003547- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003548 makes the filenames the warning module prints much more sensible
3549 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003550
Georg Brandl49aafc92007-03-07 00:34:46 +00003551- Variant of patch #697613: don't exit the interpreter on a SystemExit
3552 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003553 variable is given, but break into the interactive interpreter just
3554 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00003561
Georg Brandl0fca97a2007-03-05 22:28:08 +00003562- Patch #1674228: when assigning a slice (old-style), check for the
3563 sq_ass_slice instead of the sq_slice slot.
3564
Georg Brandl3ee81df2008-05-17 18:14:43 +00003565- When printing an unraisable error, don't print exceptions. before
3566 the name. This duplicates the behavior whening normally printing
3567 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003568
Georg Brandl3ee81df2008-05-17 18:14:43 +00003569- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00004100 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00004102

4117
Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Patch #1530482: add pydoc.render_doc() which returns the

4133
Georg Brandl92a6bae2007-03-13 17:43:32 +00004134- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004135 are set for invalid interpolation sequences that would lead to
4136 errors on reading back those values.

4190
Georg Brandl3ee81df2008-05-17 18:14:43 +00004191- unittest now verifies more of its assumptions. In particular,
4192 TestCase and TestSuite subclasses (not instances) are no longer
4193 accepted in TestSuite.addTest(). This should cause no
4194 incompatibility since it never made sense with ordinary subclasses
4195 -- the failure just occurred later, with a more cumbersome
4196 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004483 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004585 time so that opening a database previously created with the DB_DUP
4586 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4587 opens. Specifically: dictionary assignment to a DB object will
4588 replace all values for a given key when the database allows
4589 duplicate values. DB users should use DB.put(k, v) when they want
4590 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004869- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004870 periodic threadstate and signal checking in tight loops. By
4871 default, this option is turned-off. It should only be enabled in

4923-----
4924
Georg Brandl3ee81df2008-05-17 18:14:43 +00004925- Unified naming convention for free lists and their limits. All free
4926 lists in Object/ are named ``free_list``, the counter ``numfree``

Christian Heimes5b970ad2008-02-06 13:33:44 +00004929
Georg Brandl3ee81df2008-05-17 18:14:43 +00004930- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4931 to ``PyTuple_SetItem``, it can be used to populate a brand new
4932 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004933

4944
Georg Brandl3ee81df2008-05-17 18:14:43 +00004945- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4946 of w# format code incorrectly truncated the length to an int, even
4947 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4948 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004949
Georg Brandl3ee81df2008-05-17 18:14:43 +00004950- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4971- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4972 outside of pystate.c and should not be necessary.
4973
Georg Brandl3ee81df2008-05-17 18:14:43 +00004974- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4975 absolute imports. In earlier versions they might have used relative
4976 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004977
Georg Brandl3ee81df2008-05-17 18:14:43 +00004978- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4979 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004980
Georg Brandl3ee81df2008-05-17 18:14:43 +00004981- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005006- Removed the macfs module. It had been deprecated since Python 2.5.
5007 This lead to the deprecation of macostools.touched() as it relied
