73
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000074- Issue #7419: setlocale() could crash the interpreter on Windows when called
75 with invalid values.
76
Eric Smithc4ab8332009-11-29 17:40:57 +000077- Issue #3382: 'F' formatting for float and complex now convert the
78 result to upper case. This only affects 'inf' and 'nan', since 'f'
79 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +000080
Mark Dickinson9dd5e162009-11-23 20:54:09 +000081- Remove switch from "%f" formatting to "%g" formatting for floats
82 larger than 1e50 in absolute value.
83
Mark Dickinson18cfada2009-11-23 18:46:41 +000084- Remove restrictions on precision when formatting floats. E.g.,
85 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
86 requested 120 significant digits instead.
87
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000088- Add Py3k warnings for parameter names in parenthesis.
89
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000090- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000091
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000092- Issue #7085: Fix crash when importing some extensions in a thread
93 on MacOSX 10.6.
94
Mark Dickinsonb678de82009-11-19 18:41:49 +000095- Issue #7117: repr(x) for a float x returns a result based on the
96 shortest decimal string that's guaranteed to round back to x under
97 correct rounding (with round-half-to-even rounding mode).
98 Previously it gave a string based on rounding x to 17 decimal digits.
99 repr(x) for a complex number behaves similarly. On platforms where
100 the correctly-rounded strtod and dtoa code is not supported (see below),
101 repr is unchanged.
102
103- Issue #7117: On almost all platforms: float-to-string and
104 string-to-float conversions within Python are now correctly rounded.
105 Places these conversions occur include: str for floats and complex
106 numbers; the float and complex constructors; old-style and new-style
107 numeric formatting; serialization and deserialization of floats and
108 complex numbers using marshal, pickle and json; parsing of float and
109 imaginary literals in Python code; Decimal-to-float conversion.
110
111 The conversions use a Python-adapted version of David Gay's
112 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
113 functions. This code is supported on Windows, and on Unix-like
114 platforms using gcc, icc or suncc as the C compiler. There may be a
115 small number of platforms on which correct operation of this code
116 cannot be guaranteed, so the code is not used: notably, this applies
117 to platforms where the C double format is not IEEE 754 binary64, and
118 to platforms on x86 hardware where the x87 FPU is set to 64-bit
119 precision and Python's configure script is unable to determine how
120 to change the FPU precision. On these platforms conversions use the
121 platform strtod and dtoa, as before.
122
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000123- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000124 now uses the correctly-rounded string <-> float conversions
125 described above (when available), and so produces correctly rounded
126 results that will display nicely under the float repr. There are
127 two related small changes: (1) round now accepts any class with an
128 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000129 floats for the second argument), and (2) an excessively large second
130 integer argument (e.g., round(1.234, 10**100)) no longer raises an
131 exception.
132
Philip Jenveyfab8be22009-11-17 02:42:26 +0000133- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
134
Benjamin Petersone36199b2009-11-12 23:39:44 +0000135- Fix several issues with compile(). The input can now contain Windows and Mac
136 newlines and is no longer required to end in a newline.
137
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000138- Remove length limitation when constructing a complex number from a
139 unicode string.
140
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000141- Issue #7244: itertools.izip_longest() no longer ignores exceptions
142 raised during the formation of an output tuple.
143
Mark Dickinson8d87dc02009-10-25 20:39:06 +0000144- Issue #1087418: Boost performance of bitwise operations for longs.
145
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000146- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

148 interpreter is killed. Patch by Adam Olsen.
149
Eric Smithc12781a2009-10-19 14:38:14 +0000150- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

155
Benjamin Peterson196b0922009-10-15 15:44:46 +0000156- Issue #7140: The __dict__ of a module should not be cleared unless the module
157 is the only object holding a reference to it.
158
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000159- Issue #1754094: Improve the stack depth calculation in the compiler.
160 There should be no other effect than a small decrease in memory use.
161 Patch by Christopher Tur Lesniewski-Laas.
162
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000163- Issue #7084: Fix a (very unlikely) crash when printing a list from one
164 thread, and mutating it from another one. Patch by Scott Dial.
165
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +0000166- Issue #1571184: The Unicode database contains properties for more characters.

179 of producing internally inconsistent Python longs.
180
Philip Jenveydbf3b252009-09-29 04:32:44 +0000181- Issue #6990: Fix threading.local subclasses leaving old state around

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000273- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
274 (1) inf and nan strings with trailing whitespace were incorrectly
275 rejected; (2) parsing of strings representing infinities and nans
276 was locale aware; and (3) the interpretation of fromhex('-nan')
277 didn't match that of float('-nan').
278
Eric Smitha985a3a2009-05-05 18:26:08 +0000279- Issue #5920: For float.__format__, change the behavior with the
280 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
281 to be like 'g' but with at least one decimal point and with a
282 default precision of 12. Previously, the behavior the same but with
283 a default precision of 6. This more closely matches str(), and
284 reduces surprises when adding alignment flags to the empty
285 presentation type. This also affects the new complex.__format__ in
286 the same way.
287
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000288- Issue #5890: in subclasses of 'property' the __doc__ attribute was

349
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000350- Issue #4688: Add a heuristic so that tuples and dicts containing only
351 untrackable objects are not tracked by the garbage collector. This can
352 reduce the size of collections and therefore the garbage collection overhead
353 on long-running programs, depending on their particular use of datatypes.

358
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000359- Issue #4258: Make it possible to use base 2**30 instead of base
360 2**15 for the internal representation of integers, for performance
361 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
362 --enable-big-digits option to configure, which overrides the
363 default. Add sys.long_info structseq to provide information about
364 the internal format.
365
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000366- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

381 float arguments.
382
Raymond Hettinger08259e82009-02-18 23:10:19 +0000383- Running Python with the -3 option now also warns about classic division
384 for ints and longs.
385
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000386- Issue #5260: Long integers now consume less memory: average
387 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
388 on a 64-bit system.
389
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000390- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

397
Georg Brandl29c6a282009-04-05 20:23:13 +0000398- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000399 were suppressing all exceptions. These include list(), filter(), map(),
400 zip(), and bytearray().
401
Benjamin Peterson596d3062009-01-19 15:42:23 +0000402- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitrouc2f02212009-01-13 23:13:52 +0000410- Issue #4935: The overflow checking code in the expandtabs() method common
411 to str, bytes and bytearray could be optimized away by the compiler, letting
412 the interpreter segfault instead of raising an error.
413
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000414- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000421- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
422 collecting the oldest generation) so that allocating lots of objects without
423 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000424 Martin von Löwis at

428
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000429- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
430 an existing .py counterpart, override the co_filename attributes of all
431 code objects if the original filename is obsolete (which can happen if the
432 file has been renamed, moved, or if it is accessed through different paths).
433 Patch by Ziga Seilnacht and Jean-Paul Calderone.

442
Nick Coghlan180e4002008-12-30 01:18:48 +0000443- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
444 where the tp_hash and tp_dict slots are both NULL.
445
Benjamin Peterson7af65562008-12-29 17:56:58 +0000446- Issue #4764: With io.open, IOError.filename is set when trying to open a

453 bytearray.translate(). It was always allowed for bytes.translate().
454
Skip Montanarof205c132008-12-23 03:30:15 +0000455- Added test case to ensure attempts to read from a file opened for writing
456 fail.
457
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000458- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

471 exceptions.
472
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000473- Issue #4445: Replace "sizeof(PyStringObject)" with
474 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
475 str instances. On a typical machine this saves 3 bytes of memory
476 (on average) per string allocation.
477
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000478- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
479 interpreter to abort ("Fatal Python error: Could not reset the stack!")
480 instead of throwing a MemoryError.
481
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000482- Issue #3689: The list reversed iterator now supports __length_hint__

484
Benjamin Petersonc078f922008-11-21 22:27:24 +0000485- Issue #4367: Python would segfault during compiling when the unicodedata

487
Vinay Sajip213faca2008-12-03 23:22:58 +0000488- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000489 method on file objects with closefd=False. The file descriptor is still
490 kept open but the file object behaves like a closed file. The ``FileIO``
491 object also got a new readonly attribute ``closefd``.
492
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000493- Issue #4348: Some bytearray methods returned that didn't cause any change to

504
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000505- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
506 method does not return iterators for the 4th and 5th items.
507
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000508- Issue #4209: Enabling unicode_literals and the print_function in the same
509 __future__ import didn't work.
510
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000511- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000512 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000514- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
515 returned a path longer than MAX_PATH. (But It's doubtful this code path is
516 really executed because I cannot move to such directory on win2k)
517
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000518- Issue #4069: When set.remove(element) is used with a set element, the element
519 is temporarily replaced with an equivalent frozenset. But the eventual
520 KeyError would always report the empty frozenset([]) as the missing key. Now
521 it correctly refers to the initial element.

539 returned them on 64bit platforms.
540
Walter Dörwalded960ac2009-05-03 22:36:33 +0000541- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
542 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
543 step. This avoids problems with counting UTF-8 bytes that ignores the effect
544 of using the replace error handler in PyUnicode_DecodeUTF8().
545
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000546- Issue #3739: The unicode-internal encoder now reports the number of characters
547 consumed like any other encoder (instead of the number of bytes).
548
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000549- Issue #2422: When compiled with the ``--with-valgrind`` option, the
550 pymalloc allocator will be automatically disabled when running under
551 Valgrind. This gives improved memory leak detection when running
552 under Valgrind, while taking advantage of pymalloc at other times.

1731 - Packing a float now always gives a Deprecation Warning.
1732 Previously it only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
1733
1734 - If x is not an int, long or float, then packing x will always

1739 TypeError used to be raised (with a confusing error message) for
1740 'I', 'L', '*B', '*H', '*I', '*L', and struct.error in other cases.

Antoine Pitrou59c44f32009-10-30 17:07:08 +00001788- Issue #7222: Make thread "reaping" more reliable so that reference
1789 leak-chasing test runs give sensible results. The previous method of
1790 reaping threads could return successfully while some Thread objects were
1791 still referenced. This also introduces a new private function:

1810 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate

1819 test_heapq and test_warnings have been adjusted to use it, tests for
1820 other modules with both C and Python implementations in the stdlib
1821 can be adjusted to use it over time.

Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001830 that should cause a test to be skipped are now done using import_module

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001934- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1935 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1936 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1937 ``printf`` function, whereas PyString_FromFormat has an independent
1938 implementation and uses "%zd" on all platforms for size_t values.
1939 This makes a difference on win64, where ``printf`` needs "%Id" to display
1940 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001942- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1946 object; previously an int would be returned for small values. the __long__
1947 method is allowed to return either an int or a long, but the behaviour of

Vinay Sajip35e3b032008-09-01 14:33:59 +00001956 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001957 was correctly parsed but parsing of subsequent arguments failed.
1958
Vinay Sajip35e3b032008-09-01 14:33:59 +00001959- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001960 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1961 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1962 when given a tuple of classes as second argument, were looking up
1963 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1964 type object.
1965

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002103What's New in Python 2.6 beta 3?
2104================================
2105
Barry Warsaw07a4a382008-08-21 01:15:08 +00002106*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002107
2108Core and Builtins
2109-----------------
2110
Guido van Rossumf8402962008-08-20 15:01:50 +00002111- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2112 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2113 extensions do not automatically benefit from the class attribute
2114 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2115 to their tp_flags field if they care. This is a backwards
2116 compatibility feature; in 3.0, all types will use the cache by
2117 default.
2118
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002119- Keyword arguments can now follow starred arguments. (``f(a, *args,
2120 keyword=23)`` is now valid syntax.)
2121
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002122- ctypes function pointers that are COM methods have a boolean True
2123 value again.
2124
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002125- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2126 by denying s# to parse objects that have a releasebuffer procedure,
2127 and introducing s*.
2128
Georg Brandl1e13ea92008-08-11 09:07:59 +00002129- Issue #3537: Fix an assertion failure when an empty but presized dict
2130 object was stored in the freelist.
2131
Mark Dickinsonb6467572008-08-04 21:30:09 +00002132- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2133 ValueError consistently across platforms.
2134
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002135- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2136 (64bit Unix, for example), unichr() would truncate its argument and return
2137 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2138
Neal Norwitze7d8be82008-07-31 17:17:14 +00002139- Apply security patches from Apple.
2140
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002141- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2142 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2143
Antoine Pitrou92f82162008-07-25 22:22:08 +00002144- Issue #1819: function calls with several named parameters are now on
2145 average 35% faster (as measured by pybench).
2146
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002147- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2148 the python debugger steps into a class statement: the free variables (local
2149 variables defined in an outer scope) would be deleted from the outer scope.
2150
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002151- Issue #2620: Overflow checking when allocating or reallocating memory
2152 was not always being done properly in some python types and extension
2153 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2154 all been updated to perform better checks and places in the code that
2155 would previously leak memory on the error path when such an allocation
2156 failed have been fixed.

2159-------
2160
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002161- Issue #3612: Added some missing basic types in ctypes.wintypes.
2162
Benjamin Petersone977ad42008-08-20 01:42:01 +00002163- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2164 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2165
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002166- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2167 version reported by these tools does not necessarily follow the python
2168 version numbering scheme, so the module is less strict when parsing it.
2169
Nick Coghlanf70385a2008-08-18 12:42:46 +00002170- Issue #2235: Added Py3k warnings for types which will become unhashable
2171 under the stricter __hash__ inheritance rules in 3.0. Several types
2172 which did not meet the rules for hash invariants and were already
2173 unhashable in 3.0 have now been explicitly flagged as unhashable in
2174 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2175 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2176
Brett Cannon88f801d2008-08-18 00:46:22 +00002177- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2178 imported into the module but exposed as part of the module's API.
2179
Brett Cannon7b96f072008-08-18 00:41:11 +00002180- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2181
Brett Cannon46225e72008-08-18 00:36:52 +00002182- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002184- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2185
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002186- Issue #3575: Incremental decoder's decode function now takes bytearray
2187 by using 's*' instead of 't#'.
2188
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002189- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002190 fails unicode conversion on 2nd parameter. (windows only)
2191
Facundo Batista94f243a2008-08-17 03:38:39 +00002192- Issue 2464. urllib2 now supports a malformation in the URL received
2193 in a redirect.
2194
Brett Cannonabe423e2008-08-16 21:47:07 +00002195- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002196 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002197
Facundo Batistaeb90b782008-08-16 14:44:07 +00002198- Issue #2776: fixed small issue when handling an URL with double slash
2199 after a 302 response in the case of not going through a proxy.
2200
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002201- Issue #2676: in the email package, content-type parsing was hanging on
2202 pathological input because of quadratic or exponential behaviour of a
2203 regular expression.
2204
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002205- Issue #3476: binary buffered reading through the new "io" library is now
2206 thread-safe.
2207
Brett Cannonbf3157b2008-08-14 05:00:03 +00002208- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2209 since mimetools itself is deprecated. Because modules are cached, all
2210 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2211
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002212- Issue #3134: shutil referenced undefined WindowsError symbol.
2213
Robert Schuppenies14646332008-08-10 11:01:53 +00002214- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2215 menu entries were not deleted.
2216
Brett Cannon83e81842008-08-09 23:30:55 +00002217- Copied the implementation of reduce() to _functools.reduce() to have a
2218 version that did not raise a DeprecationWarning under -3.
2219
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002220- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2221 a MemoryError rather than silently stop the iteration.
2222
Guido van Rossum59ce9012008-08-09 14:55:34 +00002223- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2224 to _sre.compile() will now be rejected. This should not affect anybody
2225 since the re.compile() function never generates invalid re-bytecode.
2226
Skip Montanaroa032bf42008-08-08 22:52:51 +00002227- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2228 upon first access it can be automatically initialized from the csv file if
2229 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00002231- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2232 the reload() built-in has been removed.
2233
Brett Cannon7e30b672008-08-04 21:52:25 +00002234- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002235 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002246 asking for a specific length. This problem only affected files opened
2247 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002248

2273 file name rather than a ZipInfo instance, so files are extracted with
2274 mode 0600 rather than 000 under Unix.

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002291- Issue #643841: The language reference now provides more detailed
2292 coverage of the lookup process for special methods. The disclaimers
2293 regarding lack of coverage of new-style classes have also been

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002297What's New in Python 2.6 beta 2?
2298================================
2299
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002300*Release date: 17-Jul-2008*
2301
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002302Core and Builtins
2303-----------------
2304
Georg Brandl3e483f62008-07-16 22:57:41 +00002305- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2306 its methods now allow for items objects that can be converted to
2307 an integer using operator.index().
2308
Mark Dickinson64b7e502008-07-16 09:40:03 +00002309- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2310 produced a ValueError instead of giving the correct float.
2311
Eric Smitha5fa5a22008-07-16 00:11:49 +00002312- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2313 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2314
Mark Dickinson7103aa42008-07-15 19:08:33 +00002315- Issue #3008: the float type has a new instance method 'float.hex'
2316 and a new class method 'float.fromhex' to convert floating-point
2317 numbers to and from hexadecimal strings, respectively.
2318
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002319- Issue #2235: __hash__ is once again inherited by default. To allow
2320 collections.Hashable to remain meaningful in the presence of the
2321 default hash implementation (object.__hash__), it is now possible
2322 to explicit block inheritance of hash by setting __hash__=None at
2323 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2324 level.
2325
Nick Coghlanb028f502008-07-13 14:52:36 +00002326- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2327 the parent module cannot be found while performing an absolute import.
2328 This means that an incorrectly defined __package__ attribute will
2329 now only prevent relative imports in that module rather than causing
2330 all imports from that module to fail.
2331
Nick Coghlan14ff9942008-07-08 14:21:42 +00002332- Issue #2517: Allow unicode messages in Exceptions again by correctly
2333 bypassing the instance dictionary when looking up __unicode__ on
2334 new-style classes.
2335
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002336- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2337 set to a custom object whose write() method happens to install
2338 another file in sys.stdout.
2339
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002340- Issue #3088: Corrected a race condition in classes derived from
2341 threading.local: the first member set by a thread could be saved in
2342 another thread's dictionary.
2343
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002344- Issue #3004: Minor change to slice.indices(): the start and stop
2345 arguments are now treated identically, making the behaviour easier
2346 to describe and understand. For example, slice(None, -10,
2347 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2348 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2349 10, -1).
2350
Georg Brandl278fc502008-07-19 12:46:12 +00002351- Issue #3219: Calling a function with repeated keyword arguments,
2352 f(a=2, a=23), would not cause a syntax error. This was a regression
2353 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002354
Georg Brandl278fc502008-07-19 12:46:12 +00002355- Issue #2862: Make int and float freelist management consistent with
2356 other freelists. Changes their CompactFreeList apis into
2357 ClearFreeList apis and calls them via gc.collect().

2363 api functions without holding the GIL, which could lead to a fatal
2364 error when they failed.
2365
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002366- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2376
Vinay Sajip51e65192008-07-18 09:01:10 +00002377- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002378

2388
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002389- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002390
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002391- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2392 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002393 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002394 content-length. The problem had been corrected in the 2.4 branch, but never
2395 merged into trunk.
2396
Georg Brandle78fbcc2008-07-05 10:13:36 +00002397- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002410- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2411 handling is now the same as that of other special attributes like __name__).
2412
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002413- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2414 removal in Python 3.0 in favor of urllib2.urlopen().

2867 using the 'warning's machinery in such places as the parser where
2868 use of pure Python code is not possible. Both the ``showarning()``
2869 and ``formatwarning()`` gain an optional 'line' argument which is
2870 not called by default for backwards-compatibility reasons. Setting
2871 ``warnings.showwarning()`` to an implementation that lacks support
2872 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002935- Issue #2550: The approach used by client/server code for obtaining
2936 ports to listen on in network-oriented tests has been refined in an
2937 effort to facilitate running multiple instances of the entire
2938 regression test suite in parallel without issue.
2939 test_support.bind_port() has been fixed such that it will always
2940 return a unique port -- which wasn't always the case with the
2941 previous implementation, especially if socket options had been set
2942 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2943 new implementation of bind_port() will actually raise an exception
2944 if it is passed an AF_INET/SOCK_STREAM socket with either the
2945 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2946 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2947 the socket it's been passed. This currently only applies to
2948 Windows. This option prevents any other sockets from binding to the
2949 host/port we've bound to, thus removing the possibility of the
2950 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2951 when a second SOCK_STREAM socket binds and accepts to a host/port
2952 that's already been bound by another socket. The optional preferred
2953 port parameter to bind_port() has been removed. Under no
2954 circumstances should tests be hard coding ports!
2955
2956 test_support.find_unused_port() has also been introduced, which will
2957 pass a temporary socket object to bind_port() in order to obtain an
2958 unused port. The temporary socket object is then closed and
2959 deleted, and the port is returned. This method should only be used
2960 for obtaining an unused port in order to pass to an external program
2961 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2962 a parameter to a server-oriented class that doesn't give you direct
2963 access to the underlying socket used.
2964
2965 Finally, test_support.HOST has been introduced, which should be used
2966 for the host argument of any relevant socket calls (i.e. bind and
2967 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002968
2969 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002970 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002971 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2972 test_asynchat and test_socket_ssl.
2973
Georg Brandl3ee81df2008-05-17 18:14:43 +00002974 It is now possible for multiple instances of the regression test
2975 suite to run in parallel without issue.

3242-----------------
3243
Fred Drakea8ee94b2008-03-01 02:45:07 +00003244- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003245 644. The mode is now inherited from the py file.

3248
3249- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003250
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003251- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003252 issue 215555 for a discussion.
3253
Eric Smitha73fbe72008-02-23 03:09:44 +00003254- Added the future_builtins module, which contains hex() and oct().
3255 These are the PEP 3127 version of these functions, designed to be
3256 compatible with the hex() and oct() builtins from Python 3.0. They
3257 differ slightly in their output formats from the existing, unchanged
3258 Python 2.6 builtins. The expected usage of the future_builtins
3259 module is:
3260 from future_builtins import hex, oct
3261
Eric Smith7ef40bf2008-02-20 23:34:22 +00003262- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3263 exponents for exponents with absolute value < 100. Follows C99
3264 standard. This is a change on Windows, which would use 3 digits.
3265 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3266 so that any alterations it does to the resulting string will be
3267 available in stringlib/formatter.h (for float.__format__).
3268
Eric Smith5a3c1352008-02-19 13:21:56 +00003269- Implemented PEP 3101, Advanced String Formatting. This adds a new
3270 builtin format(); a format() method for str and unicode; a
3271 __format__() method to object, str, unicode, int, long, float, and
3272 datetime; the class string.Formatter; and the C API
3273 PyObject_Format().
3274
Georg Brandl3ee81df2008-05-17 18:14:43 +00003275- Fixed several potential crashes, all caused by specially crafted
3276 __del__ methods exploiting objects in temporarily inconsistent
3277 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003278
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003279- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003280 prevent a possible crash: an Abstract Base Class would try to access
3281 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003282

Georg Brandl3ee81df2008-05-17 18:14:43 +00003286- Clear all free lists during a gc.collect() of the highest generation
3287 in order to allow pymalloc to free more arenas. Python may give back
3288 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003289
Georg Brandl3ee81df2008-05-17 18:14:43 +00003290- Issue #2045: Fix an infinite recursion triggered when printing a
3291 subclass of collections.defaultdict, if its default_factory is set
3292 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003293
Christian Heimesf75dbef2008-02-08 00:11:31 +00003294- Fixed a minor memory leak in dictobject.c. The content of the free
3295 list was not freed on interpreter shutdown.
3296
Georg Brandl3ee81df2008-05-17 18:14:43 +00003297- Limit free list of method and builtin function objects to 256
3298 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003299
Georg Brandl3ee81df2008-05-17 18:14:43 +00003300- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3301 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003302 to compact the internal free lists of pre-allocted ints and floats.
3303
Georg Brandl3ee81df2008-05-17 18:14:43 +00003304- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3305 calls. Python expected the return type int but the fork familie
3306 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003307
Georg Brandl3ee81df2008-05-17 18:14:43 +00003308- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3318 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003319
Georg Brandl3ee81df2008-05-17 18:14:43 +00003320- Patch #1473257: generator objects gain a gi_code attribute. This is
3321 the same object as the func_code attribute of the function that
3322 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003323
Georg Brandl3ee81df2008-05-17 18:14:43 +00003324- Issue #1920: "while 0" statements were completely removed by the
3325 compiler, even in the presence of an "else" clause, which is
3326 supposed to be run when the condition is false. Now the compiler
3327 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003328
Guido van Rossumeead05f2008-01-24 18:21:02 +00003329- A few crashers fixed: weakref_in_del.py (issue #1377858);
3330 loosing_dict_ref.py (issue #1303614, test67.py);
3331 borrowed_ref_[34].py (not in tracker).
3332
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003333- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003334 suppressed while an extension is loaded by calling SetErrorMode in

3336
Georg Brandl3ee81df2008-05-17 18:14:43 +00003337- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003338 several extension methods and modules do not work without unicode
3339 support.
3340
Georg Brandl26543b12008-01-21 18:36:51 +00003341- Issue #1882: when compiling code from a string, encoding cookies in the
3342 second line of code were not always recognized correctly.
3343
Georg Brandl14404b62008-01-19 19:27:05 +00003344- Issue #1679: "0x" was taken as a valid integer literal.
3345
Georg Brandl6caad7d2008-01-26 14:19:22 +00003346- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003347 added.
3348
Christian Heimesc94e2b52008-01-14 04:13:37 +00003349- sys.float_info / PyFloat_GetInfo: The floating point information
3350 object was converted from a dict to a specialized structseq object.
3351
Georg Brandl3ee81df2008-05-17 18:14:43 +00003352- Patch #1816: Added sys.flags structseq. It exposes the status of
3353 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003354
Georg Brandl3ee81df2008-05-17 18:14:43 +00003355- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00003359- Patch #1700288: added a type attribute cache that caches method
3360 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003361
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003362- Bug #1776: __import__() no longer accepts filenames on any platform.
3363 The first parameter to __import__() must be a valid module name.

3368 envvar and sys.dont_write_bytecode attribute. All these can be set
3369 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003371- Improve some exception messages when Windows fails to load an
3372 extension module. Now we get for example '%1 is not a valid Win32
3373 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003380- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381 and INF. float("nan"), float("inf") and float("-inf") now work on
3382 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Compiler now generates simpler and faster code for dictionary
3385 literals. The oparg for BUILD_MAP now indicates an estimated
3386 dictionary size. There is a new opcode, STORE_MAP, for adding
3387 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003416- Patch #1739468: Directories and zipfiles containing a __main__.py
3417 file can now be directly executed by passing their name to the
3418 interpreter. The directory/zipfile is automatically inserted as the
3419 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003421- Issue #1265: Fix a problem with sys.settrace, if the tracing
3422 function uses a generator expression when at the same time the
3423 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003424
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003425- sets and frozensets now have an isdisjoint() method.

3430
Georg Brandl3ee81df2008-05-17 18:14:43 +00003431- The enumerate() builtin function is no longer bounded to sequences
3432 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3433 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003434
Georg Brandl3ee81df2008-05-17 18:14:43 +00003435- Issue #1686386: Tuple's tp_repr did not take into account the
3436 possibility of having a self-referential tuple, which is possible
3437 from C code. Nor did object's tp_str consider that a type's tp_str
3438 could do something that could lead to an inifinite recursion.
3439 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3440 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003441
Georg Brandl3ee81df2008-05-17 18:14:43 +00003442- Issue #1164: It was possible to trigger deadlock when using the
3443 'print' statement to write to a file since the GIL was not released
3444 as needed. Now PyObject_Print() does the right thing along with
3445 various tp_print implementations of the built-in types and those in
3446 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003447
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- Issue #1147: Exceptions were directly allowing string exceptions in
3449 their throw() method even though string exceptions no longer
3450 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003451
Georg Brandl3ee81df2008-05-17 18:14:43 +00003452- Issue #1096: Prevent a segfault from getting the repr of a very
3453 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003454
Brett Cannon1e534b52007-09-07 04:18:30 +00003455- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003456 PyObject_Call() never calling back out to Python code to trigger
3457 recursion depth updates/checks. Required the creation of a static
3458 RuntimeError instance in case normalizing an exception put the
3459 recursion check value past its limit. Fixes crashers
3460 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003461

Neal Norwitz0ac60192007-05-27 04:08:54 +00003475- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003476 __*__ attributes. (Some already existed, e.g., __doc__ and
3477 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003478
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003479- Add -3 option to the interpreter to warn about features that are
3480 deprecated and will be changed/removed in Python 3.0.
3481
Georg Brandl2134e752007-05-21 20:34:16 +00003482- Patch #1686487: you can now pass any mapping after '**' in function
3483 calls.
3484
Collin Winter62903052007-05-18 23:11:24 +00003485- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003486 "except E as target:". This is to provide forwards compatibility
3487 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003488
Brett Cannon229cee22007-05-05 01:34:02 +00003489- Deprecate BaseException.message as per PEP 352.
3490
Georg Brandl3ee81df2008-05-17 18:14:43 +00003491- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003492 inherited from a builtin base.
3493
Vinay Sajip8549ce32007-05-06 17:53:37 +00003494- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003495 setting a plain string, ie don't expand to single letter identifiers.
3496
Raymond Hettinger13936692007-04-11 18:40:58 +00003497- Request #1191699: Slices can now be pickled.
3498
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003499- Request #1193128: str.translate() now allows a None argument for
3500 translations that only remove characters without re-mapping the
3501 remaining characters.
3502
Georg Brandl5cb76c12007-03-21 09:00:39 +00003503- Patch #1682205: a TypeError while unpacking an iterable is no longer
3504 masked by a generic one with the message "unpack non-sequence".
3505
Neal Norwitzaa754b72007-03-21 06:39:48 +00003506- Remove unused file Python/fmod.c.
3507
Guido van Rossum143b5642007-03-23 04:58:42 +00003508- Bug #1683368: The object.__init__() and object.__new__() methods are
3509 now stricter in rejecting excess arguments. The only time when
3510 either allows excess arguments is when it is not overridden and the
3511 other one is. For backwards compatibility, when both are
3512 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003513 warning later). Also, type.__init__() insists on the same signature
3514 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003515
Georg Brandl3ee81df2008-05-17 18:14:43 +00003516- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3517 object to complex using its __complex__() method before falling back
3518 to the __float__() method. Therefore, the functions in the cmath
3519 module now can operate on objects that define a __complex__()
3520 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003521
Georg Brandl3ee81df2008-05-17 18:14:43 +00003522- Patch #1623563: allow __class__ assignment for classes with
3523 __slots__. The old and the new class are still required to have the
3524 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003525
Georg Brandl3ee81df2008-05-17 18:14:43 +00003526- Patch #1642547: Fix an error/crash when encountering syntax errors

3530 ``object.__reduce_ex__()`` is called with an object that is faking
3531 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003532
Georg Brandl3ee81df2008-05-17 18:14:43 +00003533- Patch #1680015: Don't modify __slots__ tuple if it contains an

3537
Georg Brandl7b9c5552007-03-12 14:30:05 +00003538- Bug #1678647: write a newline after printing an exception in any
3539 case, even when converting the value to a string failed.
3540
Georg Brandl871f1bc2007-03-12 13:17:36 +00003541- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003542 its argument, if it exists. If not, it will work like before. This
3543 allows customizing the output of dir() in the presence of a
3544 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003545
Collin Winter276887b2007-03-12 16:11:39 +00003546- Patch #922167: Python no longer segfaults when faced with infinitely
3547 self-recursive reload() calls (as reported by bug #742342).
3548
Georg Brandl3ee81df2008-05-17 18:14:43 +00003549- Patch #1675981: remove unreachable code from ``type.__new__()``

3553 parthensized forms. This means complex(repr(x)) now works instead of
3554 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003555
Georg Brandlaa2321b2007-03-07 00:40:28 +00003556- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003557 makes the filenames the warning module prints much more sensible
3558 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003559
Georg Brandl49aafc92007-03-07 00:34:46 +00003560- Variant of patch #697613: don't exit the interpreter on a SystemExit
3561 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003562 variable is given, but break into the interactive interpreter just
3563 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003571- Patch #1674228: when assigning a slice (old-style), check for the
3572 sq_ass_slice instead of the sq_slice slot.
3573
Georg Brandl3ee81df2008-05-17 18:14:43 +00003574- When printing an unraisable error, don't print exceptions. before
3575 the name. This duplicates the behavior whening normally printing
3576 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004109 AttributeError instead of an IOError when the server's response
4110 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004111

Georg Brandl3ee81df2008-05-17 18:14:43 +00004116- Patch #1429539: pdb now correctly initializes the __main__ module
4117 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004118 correctly now.
4119

4126
Georg Brandl3ee81df2008-05-17 18:14:43 +00004127- Patch #1530482: add pydoc.render_doc() which returns the

4142
Georg Brandl92a6bae2007-03-13 17:43:32 +00004143- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004144 are set for invalid interpolation sequences that would lead to
4145 errors on reading back those values.

4186

4188 returned string up to the first NUL character.

4199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- unittest now verifies more of its assumptions. In particular,
4201 TestCase and TestSuite subclasses (not instances) are no longer
4202 accepted in TestSuite.addTest(). This should cause no
4203 incompatibility since it never made sense with ordinary subclasses
4204 -- the failure just occurred later, with a more cumbersome
4205 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004206

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004593- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004594 time so that opening a database previously created with the DB_DUP
4595 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4596 opens. Specifically: dictionary assignment to a DB object will
4597 replace all values for a given key when the database allows
4598 duplicate values. DB users should use DB.put(k, v) when they want
4599 to store duplicates; not DB[k] = v.

4606 characters with ASCII value less than 32. Also, it correctly quotes
4607 dots only if they occur on a single line, as opposed to the previous
4608 behavior of quoting dots if they are the second character of any
4609 line.

4955 of w# format code incorrectly truncated the length to an int, even
4956 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4957 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004987- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4988 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
