34 with invalid values.
35
Eric Smithc4ab8332009-11-29 17:40:57 +000036- Issue #3382: 'F' formatting for float and complex now convert the
37 result to upper case. This only affects 'inf' and 'nan', since 'f'
38 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000039
Mark Dickinson9dd5e162009-11-23 20:54:09 +000040- Remove switch from "%f" formatting to "%g" formatting for floats
41 larger than 1e50 in absolute value.
42
Mark Dickinson18cfada2009-11-23 18:46:41 +000043- Remove restrictions on precision when formatting floats. E.g.,
44 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
45 requested 120 significant digits instead.
46
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000047- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +000051- Issue #7085: Fix crash when importing some extensions in a thread
52 on MacOSX 10.6.
53
Mark Dickinsonb678de82009-11-19 18:41:49 +000054- Issue #7117: repr(x) for a float x returns a result based on the
55 shortest decimal string that's guaranteed to round back to x under
56 correct rounding (with round-half-to-even rounding mode).
57 Previously it gave a string based on rounding x to 17 decimal digits.
58 repr(x) for a complex number behaves similarly. On platforms where
59 the correctly-rounded strtod and dtoa code is not supported (see below),
60 repr is unchanged.
61
62- Issue #7117: On almost all platforms: float-to-string and
63 string-to-float conversions within Python are now correctly rounded.
64 Places these conversions occur include: str for floats and complex
65 numbers; the float and complex constructors; old-style and new-style
66 numeric formatting; serialization and deserialization of floats and
67 complex numbers using marshal, pickle and json; parsing of float and
68 imaginary literals in Python code; Decimal-to-float conversion.
69
70 The conversions use a Python-adapted version of David Gay's
71 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
72 functions. This code is supported on Windows, and on Unix-like
73 platforms using gcc, icc or suncc as the C compiler. There may be a
74 small number of platforms on which correct operation of this code
75 cannot be guaranteed, so the code is not used: notably, this applies
76 to platforms where the C double format is not IEEE 754 binary64, and
77 to platforms on x86 hardware where the x87 FPU is set to 64-bit
78 precision and Python's configure script is unable to determine how
79 to change the FPU precision. On these platforms conversions use the
80 platform strtod and dtoa, as before.
81
Mark Dickinsonbd15a062009-11-18 19:33:35 +000082- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000083 now uses the correctly-rounded string <-> float conversions
84 described above (when available), and so produces correctly rounded
85 results that will display nicely under the float repr. There are
86 two related small changes: (1) round now accepts any class with an
87 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000088 floats for the second argument), and (2) an excessively large second
89 integer argument (e.g., round(1.234, 10**100)) no longer raises an
90 exception.
91
Philip Jenveyfab8be22009-11-17 02:42:26 +000092- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
93
Benjamin Petersone36199b2009-11-12 23:39:44 +000094- Fix several issues with compile(). The input can now contain Windows and Mac
95 newlines and is no longer required to end in a newline.
96

98 unicode string.
99
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000100- Issue #7244: itertools.izip_longest() no longer ignores exceptions

234 rejected; (2) parsing of strings representing infinities and nans
235 was locale aware; and (3) the interpretation of fromhex('-nan')
236 didn't match that of float('-nan').
237
Eric Smitha985a3a2009-05-05 18:26:08 +0000238- Issue #5920: For float.__format__, change the behavior with the
239 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
240 to be like 'g' but with at least one decimal point and with a
241 default precision of 12. Previously, the behavior the same but with
242 a default precision of 6. This more closely matches str(), and
243 reduces surprises when adding alignment flags to the empty
244 presentation type. This also affects the new complex.__format__ in
245 the same way.

307 the end sys.path, for compatibility with the system install of Python.
308
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000309- Issue #4688: Add a heuristic so that tuples and dicts containing only
310 untrackable objects are not tracked by the garbage collector. This can
311 reduce the size of collections and therefore the garbage collection overhead
312 on long-running programs, depending on their particular use of datatypes.
313
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000314- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
315 improve its performance. Long divisions and remainder operations
316 are now between 50% and 150% faster.
317
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000318- Issue #4258: Make it possible to use base 2**30 instead of base
319 2**15 for the internal representation of integers, for performance
320 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
321 --enable-big-digits option to configure, which overrides the
322 default. Add sys.long_info structseq to provide information about
323 the internal format.
324
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000325- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
326 result traceback.__members__ no longer exists.)
327
Mark Dickinson6b265f12009-03-18 16:07:26 +0000328- Issue #4474: PyUnicode_FromWideChar now converts characters outside
329 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
330 and sizeof(Py_UNICODE) == 2.
331
Eric Smith6f42edb2009-03-14 11:57:26 +0000332- Issue #5237: Allow auto-numbered fields in str.format(). For
333 example: '{} {}'.format(1, 2) == '1 2'.
334
Brett Cannon6c4cff02009-03-11 04:51:06 +0000335- Issue #3652: Make the 'line' argument for warnings.showwarning() a
336 requirement. Means the DeprecationWarning from Python 2.6 can go away.
337
Eric Smithe9fb6862009-02-20 14:02:36 +0000338- Issue #5247: Improve error message when unknown format codes are
339 used when using str.format() with str, unicode, long, int, and
340 float arguments.
341
Raymond Hettinger08259e82009-02-18 23:10:19 +0000342- Running Python with the -3 option now also warns about classic division
343 for ints and longs.
344
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000345- Issue #5260: Long integers now consume less memory: average
346 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
347 on a 64-bit system.
348
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000349- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
350 rotating the object pointer by 4 bits to the right.
351
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000352- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
353 it now forces its argument to double before testing for infinity.
354
Benjamin Petersone18ef192009-01-20 14:21:16 +0000355- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
356
Georg Brandl29c6a282009-04-05 20:23:13 +0000357- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000358 were suppressing all exceptions. These include list(), filter(), map(),
359 zip(), and bytearray().
360
Benjamin Peterson596d3062009-01-19 15:42:23 +0000361- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
362 functions.
363
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000364- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

366
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +0000367- Issue #4807: Port the _winreg module to Windows CE.
368
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000369- Issue #4935: The overflow checking code in the expandtabs() method common
370 to str, bytes and bytearray could be optimized away by the compiler, letting
371 the interpreter segfault instead of raising an error.
372
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000373- Issue #3720: Fix a crash when an iterator modifies its class and removes its

379
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000380- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
381 collecting the oldest generation) so that allocating lots of objects without
382 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000383 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000384 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

387
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000388- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
389 an existing .py counterpart, override the co_filename attributes of all
390 code objects if the original filename is obsolete (which can happen if the
391 file has been renamed, moved, or if it is accessed through different paths).
392 Patch by Ziga Seilnacht and Jean-Paul Calderone.
393
Martin v. Löwis5344c992009-01-02 20:32:55 +0000394- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000396- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
397 file with `str' filename on Windows.
398
Antoine Pitrouaa687902009-01-01 14:11:22 +0000399- Issue #3680: Reference cycles created through a dict, set or deque iterator
400 did not get collected.
401
Nick Coghlan180e4002008-12-30 01:18:48 +0000402- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
403 where the tp_hash and tp_dict slots are both NULL.
404
Benjamin Peterson7af65562008-12-29 17:56:58 +0000405- Issue #4764: With io.open, IOError.filename is set when trying to open a
406 directory on POSIX systems.
407
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000408- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
409 systems.
410
Georg Brandl6425a2f2008-12-28 11:54:53 +0000411- Issue #4759: None is now allowed as the first argument of
412 bytearray.translate(). It was always allowed for bytes.translate().
413
Skip Montanarof205c132008-12-23 03:30:15 +0000414- Added test case to ensure attempts to read from a file opened for writing
415 fail.
416
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000417- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

419 unreachable. Original patch by Neil Schemenauer.
420
Mark Dickinson1a707982008-12-17 16:14:37 +0000421- Issue #3439: Add a bit_length method to int and long.

425
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000426- Issue #4597: Fixed exception handling when the __exit__ function of a
427 context manager returns a value that cannot be converted to a bool.
428
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000429- Issue #4597: Fixed several opcodes that weren't always propagating
430 exceptions.
431
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000432- Issue #4445: Replace "sizeof(PyStringObject)" with
433 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
434 str instances. On a typical machine this saves 3 bytes of memory
435 (on average) per string allocation.
436
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000437- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
438 interpreter to abort ("Fatal Python error: Could not reset the stack!")
439 instead of throwing a MemoryError.
440
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000441- Issue #3689: The list reversed iterator now supports __length_hint__
442 instead of __len__. Behavior now matches other reversed iterators.
443
Benjamin Petersonc078f922008-11-21 22:27:24 +0000444- Issue #4367: Python would segfault during compiling when the unicodedata
445 module couldn't be imported and \N escapes were present.
446
Vinay Sajip213faca2008-12-03 23:22:58 +0000447- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000448 method on file objects with closefd=False. The file descriptor is still
449 kept open but the file object behaves like a closed file. The ``FileIO``
450 object also got a new readonly attribute ``closefd``.
451
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000452- Issue #4348: Some bytearray methods returned that didn't cause any change to
453 the bytearray, returned the same bytearray instead of a copy.
454
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000455- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
456
Benjamin Peterson273c2332008-11-17 22:39:09 +0000457- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
458
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000459- Issue #4048: The parser module now correctly validates relative imports.
460
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000461- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
462 exec statement.
463
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000464- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
465 method does not return iterators for the 4th and 5th items.
466
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000467- Issue #4209: Enabling unicode_literals and the print_function in the same
468 __future__ import didn't work.
469
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000470- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000471 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000472
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000473- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
474 returned a path longer than MAX_PATH. (But It's doubtful this code path is
475 really executed because I cannot move to such directory on win2k)
476
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000477- Issue #4069: When set.remove(element) is used with a set element, the element
478 is temporarily replaced with an equivalent frozenset. But the eventual
479 KeyError would always report the empty frozenset([]) as the missing key. Now
480 it correctly refers to the initial element.
481
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000482- Issue #4509: Various issues surrounding resize of bytearray objects to
483 which there are buffer exports.

493
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000494- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
495 to avoid compiler warnings.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000497- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
498 returned them on 64bit platforms.
499
Walter Dörwalded960ac2009-05-03 22:36:33 +0000500- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
501 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
502 step. This avoids problems with counting UTF-8 bytes that ignores the effect
503 of using the replace error handler in PyUnicode_DecodeUTF8().
504
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000505- Issue #3739: The unicode-internal encoder now reports the number of characters
506 consumed like any other encoder (instead of the number of bytes).
507
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000508- Issue #2422: When compiled with the ``--with-valgrind`` option, the
509 pymalloc allocator will be automatically disabled when running under
510 Valgrind. This gives improved memory leak detection when running
511 under Valgrind, while taking advantage of pymalloc at other times.

1745 leak-chasing test runs give sensible results. The previous method of

1889
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001890- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1891 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1892 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1893 ``printf`` function, whereas PyString_FromFormat has an independent
1894 implementation and uses "%zd" on all platforms for size_t values.
1895 This makes a difference on win64, where ``printf`` needs "%Id" to display
1896 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001913 was correctly parsed but parsing of subsequent arguments failed.
1914
Vinay Sajip35e3b032008-09-01 14:33:59 +00001915- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001916 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1917 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1918 when given a tuple of classes as second argument, were looking up
1919 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1920 type object.

1992 for catch_warnings() also led to an improvement in the raising of a
1993 DeprecationWarning related to warnings.warn_explicit().
1994
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001995- The deprecation warnings for the old camelCase threading API were removed.

1998
Christian Heimesa27a62e2008-08-22 19:55:54 +00001999- Silenced a trivial compiler warning in the sqlite module.
2000
Christian Heimes1cc69632008-08-22 20:10:27 +00002001- Fixed two format strings in the _collections module.
2002
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002003- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a

2016 _check_logger_class from multiprocessing.
2017
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002018- Issue #2975: When compiling several extension modules with Visual Studio 2008
2019 from the same python interpreter, some environment variables would grow
2020 without limit.
2021
Benjamin Peterson37346b22008-08-23 20:27:43 +00002022- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2023 exploitation of poor argument checking.
2024
Gerhard Häringef2276b2008-09-12 13:54:06 +00002025- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
2026
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00002027- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
2028 remaining ones have "pysqlite_" prefix.
2029
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002030- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002059What's New in Python 2.6 beta 3?
2060================================
2061
Barry Warsaw07a4a382008-08-21 01:15:08 +00002062*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002063
2064Core and Builtins
2065-----------------
2066
Guido van Rossumf8402962008-08-20 15:01:50 +00002067- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2068 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2069 extensions do not automatically benefit from the class attribute
2070 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2071 to their tp_flags field if they care. This is a backwards
2072 compatibility feature; in 3.0, all types will use the cache by
2073 default.
2074
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002075- Keyword arguments can now follow starred arguments. (``f(a, *args,
2076 keyword=23)`` is now valid syntax.)
2077
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002078- ctypes function pointers that are COM methods have a boolean True
2079 value again.
2080
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002081- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2082 by denying s# to parse objects that have a releasebuffer procedure,
2083 and introducing s*.
2084
Georg Brandl1e13ea92008-08-11 09:07:59 +00002085- Issue #3537: Fix an assertion failure when an empty but presized dict
2086 object was stored in the freelist.
2087
Mark Dickinsonb6467572008-08-04 21:30:09 +00002088- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2089 ValueError consistently across platforms.
2090
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002091- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2092 (64bit Unix, for example), unichr() would truncate its argument and return
2093 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2094
Neal Norwitze7d8be82008-07-31 17:17:14 +00002095- Apply security patches from Apple.
2096
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002097- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2098 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2099
Antoine Pitrou92f82162008-07-25 22:22:08 +00002100- Issue #1819: function calls with several named parameters are now on
2101 average 35% faster (as measured by pybench).
2102
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002103- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2104 the python debugger steps into a class statement: the free variables (local
2105 variables defined in an outer scope) would be deleted from the outer scope.
2106
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002107- Issue #2620: Overflow checking when allocating or reallocating memory
2108 was not always being done properly in some python types and extension
2109 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2110 all been updated to perform better checks and places in the code that
2111 would previously leak memory on the error path when such an allocation
2112 failed have been fixed.
2113
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002114Library
2115-------
2116
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002117- Issue #3612: Added some missing basic types in ctypes.wintypes.
2118
Benjamin Petersone977ad42008-08-20 01:42:01 +00002119- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2120 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2121
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002122- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2123 version reported by these tools does not necessarily follow the python
2124 version numbering scheme, so the module is less strict when parsing it.
2125
Nick Coghlanf70385a2008-08-18 12:42:46 +00002126- Issue #2235: Added Py3k warnings for types which will become unhashable
2127 under the stricter __hash__ inheritance rules in 3.0. Several types
2128 which did not meet the rules for hash invariants and were already
2129 unhashable in 3.0 have now been explicitly flagged as unhashable in
2130 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2131 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2132
Brett Cannon88f801d2008-08-18 00:46:22 +00002133- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2134 imported into the module but exposed as part of the module's API.

2141
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002142- Issue #3575: Incremental decoder's decode function now takes bytearray
2143 by using 's*' instead of 't#'.
2144
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002145- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002146 fails unicode conversion on 2nd parameter. (windows only)
2147
Facundo Batista94f243a2008-08-17 03:38:39 +00002148- Issue 2464. urllib2 now supports a malformation in the URL received
2149 in a redirect.
2150
Brett Cannonabe423e2008-08-16 21:47:07 +00002151- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002152 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002153
Facundo Batistaeb90b782008-08-16 14:44:07 +00002154- Issue #2776: fixed small issue when handling an URL with double slash
2155 after a 302 response in the case of not going through a proxy.
2156
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002157- Issue #2676: in the email package, content-type parsing was hanging on
2158 pathological input because of quadratic or exponential behaviour of a
2159 regular expression.
2160
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002161- Issue #3476: binary buffered reading through the new "io" library is now
2162 thread-safe.
2163
Brett Cannonbf3157b2008-08-14 05:00:03 +00002164- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2165 since mimetools itself is deprecated. Because modules are cached, all
2166 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2167
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002168- Issue #3134: shutil referenced undefined WindowsError symbol.
2169
Robert Schuppenies14646332008-08-10 11:01:53 +00002170- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2171 menu entries were not deleted.
2172
Brett Cannon83e81842008-08-09 23:30:55 +00002173- Copied the implementation of reduce() to _functools.reduce() to have a
2174 version that did not raise a DeprecationWarning under -3.
2175
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002176- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2177 a MemoryError rather than silently stop the iteration.
2178
Guido van Rossum59ce9012008-08-09 14:55:34 +00002179- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2180 to _sre.compile() will now be rejected. This should not affect anybody
2181 since the re.compile() function never generates invalid re-bytecode.
2182
Skip Montanaroa032bf42008-08-08 22:52:51 +00002183- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2184 upon first access it can be automatically initialized from the csv file if
2185 it wasn't initialized during instantiation.
2186
Brett Cannon3aa2a492008-08-06 22:28:09 +00002187- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2188 the reload() built-in has been removed.
2189
Brett Cannon7e30b672008-08-04 21:52:25 +00002190- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002191 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2199 raised an AttributeError.
2200

Antoine Pitroude781a42008-08-09 12:43:23 +00002202 asking for a specific length. This problem only affected files opened
2203 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002204

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002228- Issue #3394: zipfile.writestr sets external attributes when passed a
2229 file name rather than a ZipInfo instance, so files are extracted with
2230 mode 0600 rather than 000 under Unix.
2231
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002232- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2233 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002244- Issue #2235: the C API function PyObject_HashNotImplemented and its
2245 interaction with the tp_hash slot (added in 2.6b2) are now documented
2246

2248 coverage of the lookup process for special methods. The disclaimers
2249 regarding lack of coverage of new-style classes have also been
2250 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002253What's New in Python 2.6 beta 2?
2254================================
2255
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002256*Release date: 17-Jul-2008*
2257
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002258Core and Builtins
2259-----------------
2260
Georg Brandl3e483f62008-07-16 22:57:41 +00002261- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2262 its methods now allow for items objects that can be converted to
2263 an integer using operator.index().
2264
Mark Dickinson64b7e502008-07-16 09:40:03 +00002265- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2266 produced a ValueError instead of giving the correct float.
2267
Eric Smitha5fa5a22008-07-16 00:11:49 +00002268- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2269 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2270
Mark Dickinson7103aa42008-07-15 19:08:33 +00002271- Issue #3008: the float type has a new instance method 'float.hex'
2272 and a new class method 'float.fromhex' to convert floating-point
2273 numbers to and from hexadecimal strings, respectively.
2274
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002275- Issue #2235: __hash__ is once again inherited by default. To allow
2276 collections.Hashable to remain meaningful in the presence of the
2277 default hash implementation (object.__hash__), it is now possible
2278 to explicit block inheritance of hash by setting __hash__=None at
2279 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2280 level.
2281
Nick Coghlanb028f502008-07-13 14:52:36 +00002282- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2283 the parent module cannot be found while performing an absolute import.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002759 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002760

Georg Brandl3ee81df2008-05-17 18:14:43 +00002821- Issue #1631171: Re-implement the 'warnings' module in C (the
2822 original Python code has been kept as backup). This will allow for
2823 using the 'warning's machinery in such places as the parser where
2824 use of pure Python code is not possible. Both the ``showarning()``
2825 and ``formatwarning()`` gain an optional 'line' argument which is
2826 not called by default for backwards-compatibility reasons. Setting
2827 ``warnings.showwarning()`` to an implementation that lacks support
2828 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002891- Issue #2550: The approach used by client/server code for obtaining
2892 ports to listen on in network-oriented tests has been refined in an
2893 effort to facilitate running multiple instances of the entire
2894 regression test suite in parallel without issue.
2895 test_support.bind_port() has been fixed such that it will always
2896 return a unique port -- which wasn't always the case with the
2897 previous implementation, especially if socket options had been set
2898 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2899 new implementation of bind_port() will actually raise an exception
2900 if it is passed an AF_INET/SOCK_STREAM socket with either the
2901 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2902 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2903 the socket it's been passed. This currently only applies to
2904 Windows. This option prevents any other sockets from binding to the
2905 host/port we've bound to, thus removing the possibility of the
2906 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2907 when a second SOCK_STREAM socket binds and accepts to a host/port
2908 that's already been bound by another socket. The optional preferred
2909 port parameter to bind_port() has been removed. Under no
2910 circumstances should tests be hard coding ports!
2911
2912 test_support.find_unused_port() has also been introduced, which will
2913 pass a temporary socket object to bind_port() in order to obtain an
2914 unused port. The temporary socket object is then closed and
2915 deleted, and the port is returned. This method should only be used
2916 for obtaining an unused port in order to pass to an external program
2917 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2918 a parameter to a server-oriented class that doesn't give you direct
2919 access to the underlying socket used.
2920
2921 Finally, test_support.HOST has been introduced, which should be used
2922 for the host argument of any relevant socket calls (i.e. bind and
2923 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002924
2925 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002926 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002927 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2928 test_asynchat and test_socket_ssl.
2929
Georg Brandl3ee81df2008-05-17 18:14:43 +00002930 It is now possible for multiple instances of the regression test
2931 suite to run in parallel without issue.

3199
Fred Drakea8ee94b2008-03-01 02:45:07 +00003200- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003201 644. The mode is now inherited from the py file.

3204
3205- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003206
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003207- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003208 issue 215555 for a discussion.
3209
Eric Smitha73fbe72008-02-23 03:09:44 +00003210- Added the future_builtins module, which contains hex() and oct().
3211 These are the PEP 3127 version of these functions, designed to be
3212 compatible with the hex() and oct() builtins from Python 3.0. They
3213 differ slightly in their output formats from the existing, unchanged
3214 Python 2.6 builtins. The expected usage of the future_builtins
3215 module is:
3216 from future_builtins import hex, oct
3217
Eric Smith7ef40bf2008-02-20 23:34:22 +00003218- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3219 exponents for exponents with absolute value < 100. Follows C99
3220 standard. This is a change on Windows, which would use 3 digits.
3221 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3222 so that any alterations it does to the resulting string will be
3223 available in stringlib/formatter.h (for float.__format__).
3224
Eric Smith5a3c1352008-02-19 13:21:56 +00003225- Implemented PEP 3101, Advanced String Formatting. This adds a new
3226 builtin format(); a format() method for str and unicode; a
3227 __format__() method to object, str, unicode, int, long, float, and
3228 datetime; the class string.Formatter; and the C API
3229 PyObject_Format().
3230
Georg Brandl3ee81df2008-05-17 18:14:43 +00003231- Fixed several potential crashes, all caused by specially crafted
3232 __del__ methods exploiting objects in temporarily inconsistent
3233 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003234
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003235- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003236 prevent a possible crash: an Abstract Base Class would try to access
3237 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003238

Georg Brandl3ee81df2008-05-17 18:14:43 +00003242- Clear all free lists during a gc.collect() of the highest generation
3243 in order to allow pymalloc to free more arenas. Python may give back
3244 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003245
Georg Brandl3ee81df2008-05-17 18:14:43 +00003246- Issue #2045: Fix an infinite recursion triggered when printing a
3247 subclass of collections.defaultdict, if its default_factory is set
3248 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003249
Christian Heimesf75dbef2008-02-08 00:11:31 +00003250- Fixed a minor memory leak in dictobject.c. The content of the free
3251 list was not freed on interpreter shutdown.
3252
Georg Brandl3ee81df2008-05-17 18:14:43 +00003253- Limit free list of method and builtin function objects to 256
3254 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003255
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3257 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003258 to compact the internal free lists of pre-allocted ints and floats.
3259
Georg Brandl3ee81df2008-05-17 18:14:43 +00003260- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3261 calls. Python expected the return type int but the fork familie
3262 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003263
Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3265 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003273- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3274 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003275
Georg Brandl3ee81df2008-05-17 18:14:43 +00003276- Patch #1473257: generator objects gain a gi_code attribute. This is
3277 the same object as the func_code attribute of the function that
3278 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003279
Georg Brandl3ee81df2008-05-17 18:14:43 +00003280- Issue #1920: "while 0" statements were completely removed by the
3281 compiler, even in the presence of an "else" clause, which is
3282 supposed to be run when the condition is false. Now the compiler
3283 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003284
Guido van Rossumeead05f2008-01-24 18:21:02 +00003285- A few crashers fixed: weakref_in_del.py (issue #1377858);
3286 loosing_dict_ref.py (issue #1303614, test67.py);
3287 borrowed_ref_[34].py (not in tracker).
3288
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003289- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003290 suppressed while an extension is loaded by calling SetErrorMode in
3291 dynload_win.c. The error is still reported properly.
3292
Georg Brandl3ee81df2008-05-17 18:14:43 +00003293- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003294 several extension methods and modules do not work without unicode
3295 support.
3296
Georg Brandl26543b12008-01-21 18:36:51 +00003297- Issue #1882: when compiling code from a string, encoding cookies in the
3298 second line of code were not always recognized correctly.
3299
Georg Brandl14404b62008-01-19 19:27:05 +00003300- Issue #1679: "0x" was taken as a valid integer literal.
3301
Georg Brandl6caad7d2008-01-26 14:19:22 +00003302- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003303 added.
3304
Christian Heimesc94e2b52008-01-14 04:13:37 +00003305- sys.float_info / PyFloat_GetInfo: The floating point information
3306 object was converted from a dict to a specialized structseq object.
3307
Georg Brandl3ee81df2008-05-17 18:14:43 +00003308- Patch #1816: Added sys.flags structseq. It exposes the status of
3309 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003310
Georg Brandl3ee81df2008-05-17 18:14:43 +00003311- Objects/structseq.c: Implemented new structseq representation. The
3312 patch makes structseqs (e.g. the return value of os.stat) more
3313 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003314
Georg Brandl3ee81df2008-05-17 18:14:43 +00003315- Patch #1700288: added a type attribute cache that caches method

3324 envvar and sys.dont_write_bytecode attribute. All these can be set
3325 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003326
Georg Brandl3ee81df2008-05-17 18:14:43 +00003327- Improve some exception messages when Windows fails to load an
3328 extension module. Now we get for example '%1 is not a valid Win32
3329 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003330

Christian Heimes0a8143f2007-12-18 23:22:54 +00003336- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003337 and INF. float("nan"), float("inf") and float("-inf") now work on
3338 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003339
Georg Brandl3ee81df2008-05-17 18:14:43 +00003340- Compiler now generates simpler and faster code for dictionary
3341 literals. The oparg for BUILD_MAP now indicates an estimated
3342 dictionary size. There is a new opcode, STORE_MAP, for adding
3343 entries to the dictionary.

3373 file can now be directly executed by passing their name to the
3374 interpreter. The directory/zipfile is automatically inserted as the
3375 first entry in sys.path.

3386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- The enumerate() builtin function is no longer bounded to sequences
3388 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3389 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003390
Georg Brandl3ee81df2008-05-17 18:14:43 +00003391- Issue #1686386: Tuple's tp_repr did not take into account the
3392 possibility of having a self-referential tuple, which is possible
3393 from C code. Nor did object's tp_str consider that a type's tp_str
3394 could do something that could lead to an inifinite recursion.
3395 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3396 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003398- Issue #1164: It was possible to trigger deadlock when using the
3399 'print' statement to write to a file since the GIL was not released
3400 as needed. Now PyObject_Print() does the right thing along with
3401 various tp_print implementations of the built-in types and those in
3402 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003412 PyObject_Call() never calling back out to Python code to trigger
3413 recursion depth updates/checks. Required the creation of a static

3440
Collin Winter62903052007-05-18 23:11:24 +00003441- except clauses may now be spelled either "except E, target:" or

3443 with Python 3.0.

3449
Vinay Sajip8549ce32007-05-06 17:53:37 +00003450- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003451 setting a plain string, ie don't expand to single letter identifiers.
3452
Raymond Hettinger13936692007-04-11 18:40:58 +00003453- Request #1191699: Slices can now be pickled.
3454
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003455- Request #1193128: str.translate() now allows a None argument for

3463
Guido van Rossum143b5642007-03-23 04:58:42 +00003464- Bug #1683368: The object.__init__() and object.__new__() methods are
3465 now stricter in rejecting excess arguments. The only time when
3466 either allows excess arguments is when it is not overridden and the
3467 other one is. For backwards compatibility, when both are
3468 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003469 warning later). Also, type.__init__() insists on the same signature
3470 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003472- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3473 object to complex using its __complex__() method before falling back
3474 to the __float__() method. Therefore, the functions in the cmath
3475 module now can operate on objects that define a __complex__()
3476 method.

3493
Georg Brandl7b9c5552007-03-12 14:30:05 +00003494- Bug #1678647: write a newline after printing an exception in any
3495 case, even when converting the value to a string failed.
3496
Georg Brandl871f1bc2007-03-12 13:17:36 +00003497- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003498 its argument, if it exists. If not, it will work like before. This
3499 allows customizing the output of dir() in the presence of a
3500 __getattr__().

3509 parthensized forms. This means complex(repr(x)) now works instead of
3510 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003511
Georg Brandlaa2321b2007-03-07 00:40:28 +00003512- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003513 makes the filenames the warning module prints much more sensible
3514 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003527- Patch #1674228: when assigning a slice (old-style), check for the
3528 sq_ass_slice instead of the sq_slice slot.
3529
Georg Brandl3ee81df2008-05-17 18:14:43 +00003530- When printing an unraisable error, don't print exceptions. before
3531 the name. This duplicates the behavior whening normally printing
3532 exceptions.

4098
Georg Brandl92a6bae2007-03-13 17:43:32 +00004099- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004100 are set for invalid interpolation sequences that would lead to

4157 TestCase and TestSuite subclasses (not instances) are no longer
4158 accepted in TestSuite.addTest(). This should cause no
4159 incompatibility since it never made sense with ordinary subclasses
4160 -- the failure just occurred later, with a more cumbersome
4161 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004442- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4443 with RFC 3207 and forgets any knowledge obtained from the server not
4444 obtained from the TLS negotiation itself. Patch contributed by Bill
4445 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004446
Georg Brandl3ee81df2008-05-17 18:14:43 +00004447- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004448 that the SMTP.starttls() caller no longer needs to call ehlo()
4449 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004450 does not claim to support starttls. Adds the
4451 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4532 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4533 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00004535

Georg Brandl3ee81df2008-05-17 18:14:43 +00004550 time so that opening a database previously created with the DB_DUP
4551 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4552 opens. Specifically: dictionary assignment to a DB object will
4553 replace all values for a given key when the database allows
4554 duplicate values. DB users should use DB.put(k, v) when they want
4555 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004556

4562 characters with ASCII value less than 32. Also, it correctly quotes
4563 dots only if they occur on a single line, as opposed to the previous
4564 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004834- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004835 periodic threadstate and signal checking in tight loops. By
4836 default, this option is turned-off. It should only be enabled in
4837 debugged, performance critical applications.

4888-----
4889
Georg Brandl3ee81df2008-05-17 18:14:43 +00004890- Unified naming convention for free lists and their limits. All free
4891 lists in Object/ are named ``free_list``, the counter ``numfree``

4893 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004894
Georg Brandl3ee81df2008-05-17 18:14:43 +00004895- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4896 to ``PyTuple_SetItem``, it can be used to populate a brand new
4897 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004898

4909
Georg Brandl3ee81df2008-05-17 18:14:43 +00004910- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4911 of w# format code incorrectly truncated the length to an int, even
4912 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4913 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004914
Georg Brandl3ee81df2008-05-17 18:14:43 +00004915- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4935
4936- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4937 outside of pystate.c and should not be necessary.
4938
Georg Brandl3ee81df2008-05-17 18:14:43 +00004939- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4940 absolute imports. In earlier versions they might have used relative
4941 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004942
Georg Brandl3ee81df2008-05-17 18:14:43 +00004943- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4944 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004945
Georg Brandl3ee81df2008-05-17 18:14:43 +00004946- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004971- Removed the macfs module. It had been deprecated since Python 2.5.
4972 This lead to the deprecation of macostools.touched() as it relied
4973 solely on macfs and was a no-op under OS X.
