Barry Warsaw12582c92008-10-02 03:33:51 +00007What's New in Python 2.7 alpha 1
8================================
9
10*Release date: XX-XXX-20XX*
11
12Core and Builtins
13-----------------
14
Brett Cannon15ba4da2009-04-01 18:03:59 +000015- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
16
Ronald Oussorene0154ed2009-03-30 23:10:35 +000017- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
18 the end sys.path, for compatibility with the system install of Python.
19
Antoine Pitrouf8387af2009-03-23 18:41:45 +000020- Issue #4688: Add a heuristic so that tuples and dicts containing only
21 untrackable objects are not tracked by the garbage collector. This can
22 reduce the size of collections and therefore the garbage collection overhead
23 on long-running programs, depending on their particular use of datatypes.
24
Mark Dickinson0b666bf2009-03-23 18:25:13 +000025- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
26 improve its performance. Long divisions and remainder operations
27 are now between 50% and 150% faster.
28
Mark Dickinsonefc82f72009-03-20 15:51:55 +000029- Issue #4258: Make it possible to use base 2**30 instead of base
30 2**15 for the internal representation of integers, for performance
31 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
32 --enable-big-digits option to configure, which overrides the
33 default. Add sys.long_info structseq to provide information about
34 the internal format.
35
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000036- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
37 result traceback.__members__ no longer exists.)
38
Mark Dickinson6b265f12009-03-18 16:07:26 +000039- Issue #4474: PyUnicode_FromWideChar now converts characters outside
40 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
41 and sizeof(Py_UNICODE) == 2.
42
Eric Smith6f42edb2009-03-14 11:57:26 +000043- Issue #5237: Allow auto-numbered fields in str.format(). For
44 example: '{} {}'.format(1, 2) == '1 2'.
45
Brett Cannon6c4cff02009-03-11 04:51:06 +000046- Issue #3652: Make the 'line' argument for warnings.showwarning() a
47 requirement. Means the DeprecationWarning from Python 2.6 can go away.
48
Eric Smithe9fb6862009-02-20 14:02:36 +000049- Issue #5247: Improve error message when unknown format codes are
50 used when using str.format() with str, unicode, long, int, and
51 float arguments.
52
Raymond Hettinger08259e82009-02-18 23:10:19 +000053- Running Python with the -3 option now also warns about classic division
54 for ints and longs.
55
Mark Dickinson2ffb26f2009-02-15 10:13:41 +000056- Issue #5260: Long integers now consume less memory: average
57 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
58 on a 64-bit system.
59
Antoine Pitrou76a4b892009-02-13 13:52:33 +000060- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
61 rotating the object pointer by 4 bits to the right.
62
Mark Dickinsonc97c9092009-02-09 14:18:43 +000063- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
64 it now forces its argument to double before testing for infinity.
65
Benjamin Petersone18ef192009-01-20 14:21:16 +000066- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
67
Raymond Hettingerb5163702009-02-02 21:50:13 +000068- Issue 1242657: the __len__() and __length_hint__() calls in several tools
69 were suppressing all exceptions. These include list(), filter(), map(),
70 zip(), and bytearray().
71
Benjamin Peterson596d3062009-01-19 15:42:23 +000072- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
73 functions.
74
Benjamin Peterson5848d1f2009-01-19 00:08:08 +000075- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
76 OSError.
77
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +000078- Issue #4807: Port the _winreg module to Windows CE.
79
Antoine Pitrouc2f02212009-01-13 23:13:52 +000080- Issue #4935: The overflow checking code in the expandtabs() method common
81 to str, bytes and bytearray could be optimized away by the compiler, letting
82 the interpreter segfault instead of raising an error.
83
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +000084- Issue #3720: Fix a crash when an iterator modifies its class and removes its
85 __next__ method.
86
Martin v. Löwise3422fa2009-01-12 08:11:24 +000087- Issue #4893: Use NT threading on CE.
88
Martin v. Löwis1b3bef22009-01-12 07:57:11 +000089- Issue #4915: Port sysmodule to Windows CE.
90
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +000091- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
92 collecting the oldest generation) so that allocating lots of objects without
93 destroying them does not show quadratic performance. Based on a proposal by
94 Martin von Löwis at
95 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
96
Martin v. Löwisb90304a2009-01-07 18:40:40 +000097- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
98
Antoine Pitroue96d4ea2009-01-06 18:10:47 +000099- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
100 an existing .py counterpart, override the co_filename attributes of all
101 code objects if the original filename is obsolete (which can happen if the
102 file has been renamed, moved, or if it is accessed through different paths).
103 Patch by Ziga Seilnacht and Jean-Paul Calderone.
104
Martin v. Löwis5344c992009-01-02 20:32:55 +0000105- Issue #4075: Use OutputDebugStringW in Py_FatalError.
106
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000107- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
108 file with `str' filename on Windows.
109
Antoine Pitrouaa687902009-01-01 14:11:22 +0000110- Issue #3680: Reference cycles created through a dict, set or deque iterator
111 did not get collected.
112
Nick Coghlan180e4002008-12-30 01:18:48 +0000113- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
114 where the tp_hash and tp_dict slots are both NULL.
115
Benjamin Peterson7af65562008-12-29 17:56:58 +0000116- Issue #4764: With io.open, IOError.filename is set when trying to open a
117 directory on POSIX systems.
118
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000119- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
120 systems.
121
Georg Brandl6425a2f2008-12-28 11:54:53 +0000122- Issue #4759: None is now allowed as the first argument of
123 bytearray.translate(). It was always allowed for bytes.translate().
124
Skip Montanarof205c132008-12-23 03:30:15 +0000125- Added test case to ensure attempts to read from a file opened for writing
126 fail.
127
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000128- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
129 print elapsed times, not only when some objects are uncollectable /
130 unreachable. Original patch by Neil Schemenauer.
131
Mark Dickinson1a707982008-12-17 16:14:37 +0000132- Issue #3439: Add a bit_length method to int and long.
133
Antoine Pitroud0c35152008-12-17 00:38:28 +0000134- Issue #2183: Simplify and optimize bytecode for list comprehensions.
135 Original patch by Neal Norwitz.
136
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000137- Issue #4597: Fixed exception handling when the __exit__ function of a
138 context manager returns a value that cannot be converted to a bool.
139
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000140- Issue #4597: Fixed several opcodes that weren't always propagating
141 exceptions.
142
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000143- Issue #4445: Replace "sizeof(PyStringObject)" with
144 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
145 str instances. On a typical machine this saves 3 bytes of memory
146 (on average) per string allocation.
147
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000148- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
149 interpreter to abort ("Fatal Python error: Could not reset the stack!")

156 module couldn't be imported and \N escapes were present.
157
Vinay Sajip213faca2008-12-03 23:22:58 +0000158- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000159 method on file objects with closefd=False. The file descriptor is still
160 kept open but the file object behaves like a closed file. The ``FileIO``
161 object also got a new readonly attribute ``closefd``.
162
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000163- Issue #4348: Some bytearray methods returned that didn't cause any change to
164 the bytearray, returned the same bytearray instead of a copy.
165
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000166- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
167
Benjamin Peterson273c2332008-11-17 22:39:09 +0000168- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
169
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000170- Issue #4048: The parser module now correctly validates relative imports.
171
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000172- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
173 exec statement.
174
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000175- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
176 method does not return iterators for the 4th and 5th items.
177
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000178- Issue #4209: Enabling unicode_literals and the print_function in the same
179 __future__ import didn't work.
180
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000181- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000182 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000183
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000184- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
185 returned a path longer than MAX_PATH. (But It's doubtful this code path is
186 really executed because I cannot move to such directory on win2k)
187
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000188- Issue #4069: When set.remove(element) is used with a set element, the element
189 is temporarily replaced with an equivalent frozenset. But the eventual
190 KeyError would always report the empty frozenset([]) as the missing key. Now
191 it correctly refers to the initial element.
192
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000193- Issue #4509: Various issues surrounding resize of bytearray objects to
194 which there are buffer exports.
195
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000196- Issue #4748: Lambda generators no longer return a value.
197
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +0000198- Issue #3582: Use native TLS functions on Windows
199

207 to note the limitation
208
Michael Foord345b2fe2009-04-02 03:20:38 +0000209- unittest.assertNotEqual() now uses the inequality operator (!=) instead
210 of the equality operator.
211
212- Issue #5663: better failure messages for unittest asserts. Default assertTrue
213 and assertFalse messages are now useful. TestCase has a longMessage attribute.
214 This defaults to False, but if set to True useful error messages are shown in
215 addition to explicit messages passed to assert methods.
216

226 threads.
227
Raymond Hettinger66c4a6b2009-04-01 18:50:56 +0000228- Issue #5647: MutableSet.__iand__() no longer mutates self during iteration.

231
R. David Murraya83da352009-04-01 03:21:43 +0000232- Issue #2522: locale.format now checks its first argument to ensure it has
233 been passed only one pattern, avoiding mysterious errors where it appeared
234 that it was failing to do localization.
235
Tarek Ziadé9e47ce42009-03-31 22:27:23 +0000236- Issue #5583: Added optional Extensions in Distutils. Initial patch by Georg
237 Brandl.
238
Jesse Noller42f9b4e2009-03-31 22:20:35 +0000239- Issue #5619: Multiprocessing children disobey the debug flag and causes

250 manager use: "with multiprocessing.Lock()" works now.
251
Jesse Noller459a6482009-03-30 15:50:42 +0000252- Issue #5177: Multiprocessing's SocketListener class now uses
253 socket.SO_REUSEADDR on all connections so that the user no longer needs
254 to wait 120 seconds for the socket to expire.
255
Guilherme Polo1972d162009-03-27 21:43:08 +0000256- Adjusted _tkinter to compile without warnings when WITH_THREAD is not
257 defined (part of issue #5035).
258
Marc-André Lemburgcbdf15b2009-03-25 19:45:33 +0000259- Issue #5561: Removed the sys.version_info shortcuts from platform's
260 python_version() and python_version_tuple() since they produced different
261 output compared to previous Python versions.
262
Benjamin Peterson692428e2009-03-23 21:50:21 +0000263- Issue #1034053: unittest now supports skipping tests and expected failures.
264
Gregory P. Smith28399852009-03-31 16:54:10 +0000265- The unittest.TestCase.assertRaises() method now returns a context manager when
266 not given a callable so that code to be tested can be written inline using
267 a with statement.
268
269- The unittest.TestCase.assertEqual() now displays the differences in lists,
270 tuples, dicts and sets on failure. Many new handy type and comparison
271 specific assert* methods have been added that fail with error messages
272 actually useful for debugging. Contributed in part by Google. [Issue #2578]
273
Lars Gustäbel2020a592009-03-22 20:09:33 +0000274- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop

276 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
277 partial bzip2 compressed data.
278
Benjamin Petersonb364bfe2009-03-22 17:45:11 +0000279- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

854
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000855- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
856 PyString_FromFormat or PyErr_Format to display size_t values. The macro
857 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
858 ``printf`` function, whereas PyString_FromFormat has an independent
859 implementation and uses "%zd" on all platforms for size_t values.
860 This makes a difference on win64, where ``printf`` needs "%Id" to display
861 64bit values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000878 was correctly parsed but parsing of subsequent arguments failed.
879
Vinay Sajip35e3b032008-09-01 14:33:59 +0000880- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000881 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
882 mechanism. In the process, fix a bug where isinstance() and issubclass(),
883 when given a tuple of classes as second argument, were looking up
884 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
885 type object.

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

981 _check_logger_class from multiprocessing.
982
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000983- Issue #2975: When compiling several extension modules with Visual Studio 2008
984 from the same python interpreter, some environment variables would grow
985 without limit.
986
Benjamin Peterson37346b22008-08-23 20:27:43 +0000987- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
988 exploitation of poor argument checking.
989

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001024What's New in Python 2.6 beta 3?
1025================================
1026
Barry Warsaw07a4a382008-08-21 01:15:08 +00001027*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001028
1029Core and Builtins
1030-----------------
1031
Guido van Rossumf8402962008-08-20 15:01:50 +00001032- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1033 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1034 extensions do not automatically benefit from the class attribute
1035 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1036 to their tp_flags field if they care. This is a backwards
1037 compatibility feature; in 3.0, all types will use the cache by
1038 default.
1039
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001040- Keyword arguments can now follow starred arguments. (``f(a, *args,
1041 keyword=23)`` is now valid syntax.)
1042
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001043- ctypes function pointers that are COM methods have a boolean True
1044 value again.
1045
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001046- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1047 by denying s# to parse objects that have a releasebuffer procedure,
1048 and introducing s*.
1049
Georg Brandl1e13ea92008-08-11 09:07:59 +00001050- Issue #3537: Fix an assertion failure when an empty but presized dict
1051 object was stored in the freelist.
1052
Mark Dickinsonb6467572008-08-04 21:30:09 +00001053- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1054 ValueError consistently across platforms.
1055
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001056- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1057 (64bit Unix, for example), unichr() would truncate its argument and return
1058 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1059
Neal Norwitze7d8be82008-07-31 17:17:14 +00001060- Apply security patches from Apple.
1061
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001062- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1063 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1064
Antoine Pitrou92f82162008-07-25 22:22:08 +00001065- Issue #1819: function calls with several named parameters are now on
1066 average 35% faster (as measured by pybench).
1067
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001068- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1069 the python debugger steps into a class statement: the free variables (local
1070 variables defined in an outer scope) would be deleted from the outer scope.
1071
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001072- Issue #2620: Overflow checking when allocating or reallocating memory
1073 was not always being done properly in some python types and extension
1074 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1075 all been updated to perform better checks and places in the code that
1076 would previously leak memory on the error path when such an allocation
1077 failed have been fixed.

1080-------
1081
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001082- Issue #3612: Added some missing basic types in ctypes.wintypes.
1083
Benjamin Petersone977ad42008-08-20 01:42:01 +00001084- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1085 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1086
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001087- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1088 version reported by these tools does not necessarily follow the python
1089 version numbering scheme, so the module is less strict when parsing it.
1090
Nick Coghlanf70385a2008-08-18 12:42:46 +00001091- Issue #2235: Added Py3k warnings for types which will become unhashable
1092 under the stricter __hash__ inheritance rules in 3.0. Several types
1093 which did not meet the rules for hash invariants and were already
1094 unhashable in 3.0 have now been explicitly flagged as unhashable in
1095 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1096 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1097
Brett Cannon88f801d2008-08-18 00:46:22 +00001098- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1099 imported into the module but exposed as part of the module's API.
1100
Brett Cannon7b96f072008-08-18 00:41:11 +00001101- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1102
Brett Cannon46225e72008-08-18 00:36:52 +00001103- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001105- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1106
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001107- Issue #3575: Incremental decoder's decode function now takes bytearray
1108 by using 's*' instead of 't#'.
1109
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001110- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001111 fails unicode conversion on 2nd parameter. (windows only)
1112
Facundo Batista94f243a2008-08-17 03:38:39 +00001113- Issue 2464. urllib2 now supports a malformation in the URL received
1114 in a redirect.
1115
Brett Cannonabe423e2008-08-16 21:47:07 +00001116- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001117 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001118
Facundo Batistaeb90b782008-08-16 14:44:07 +00001119- Issue #2776: fixed small issue when handling an URL with double slash
1120 after a 302 response in the case of not going through a proxy.
1121
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001122- Issue #2676: in the email package, content-type parsing was hanging on
1123 pathological input because of quadratic or exponential behaviour of a
1124 regular expression.
1125
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001126- Issue #3476: binary buffered reading through the new "io" library is now
1127 thread-safe.
1128
Brett Cannonbf3157b2008-08-14 05:00:03 +00001129- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1130 since mimetools itself is deprecated. Because modules are cached, all
1131 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1132
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001133- Issue #3134: shutil referenced undefined WindowsError symbol.
1134
Robert Schuppenies14646332008-08-10 11:01:53 +00001135- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1136 menu entries were not deleted.
1137
Brett Cannon83e81842008-08-09 23:30:55 +00001138- Copied the implementation of reduce() to _functools.reduce() to have a
1139 version that did not raise a DeprecationWarning under -3.
1140
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001141- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1142 a MemoryError rather than silently stop the iteration.
1143
Guido van Rossum59ce9012008-08-09 14:55:34 +00001144- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1145 to _sre.compile() will now be rejected. This should not affect anybody
1146 since the re.compile() function never generates invalid re-bytecode.
1147
Skip Montanaroa032bf42008-08-08 22:52:51 +00001148- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1149 upon first access it can be automatically initialized from the csv file if
1150 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00001152- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1153 the reload() built-in has been removed.
1154
Brett Cannon7e30b672008-08-04 21:52:25 +00001155- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001156 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001167 asking for a specific length. This problem only affected files opened
1168 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001169

1183 invalid arguments.
1184

Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001197- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1198 argument in python 2.5, this broke code that subclassed Popen to include its
1199 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1210 interaction with the tp_hash slot (added in 2.6b2) are now documented
1211
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001212- Issue #643841: The language reference now provides more detailed
1213 coverage of the lookup process for special methods. The disclaimers
1214 regarding lack of coverage of new-style classes have also been
1215 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001218What's New in Python 2.6 beta 2?
1219================================
1220
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001221*Release date: 17-Jul-2008*
1222
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001223Core and Builtins
1224-----------------
1225
Georg Brandl3e483f62008-07-16 22:57:41 +00001226- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1227 its methods now allow for items objects that can be converted to
1228 an integer using operator.index().
1229
Mark Dickinson64b7e502008-07-16 09:40:03 +00001230- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1231 produced a ValueError instead of giving the correct float.
1232
Eric Smitha5fa5a22008-07-16 00:11:49 +00001233- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1234 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1235
Mark Dickinson7103aa42008-07-15 19:08:33 +00001236- Issue #3008: the float type has a new instance method 'float.hex'
1237 and a new class method 'float.fromhex' to convert floating-point
1238 numbers to and from hexadecimal strings, respectively.
1239
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001240- Issue #2235: __hash__ is once again inherited by default. To allow
1241 collections.Hashable to remain meaningful in the presence of the
1242 default hash implementation (object.__hash__), it is now possible
1243 to explicit block inheritance of hash by setting __hash__=None at
1244 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1245 level.
1246
Nick Coghlanb028f502008-07-13 14:52:36 +00001247- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1248 the parent module cannot be found while performing an absolute import.
1249 This means that an incorrectly defined __package__ attribute will
1250 now only prevent relative imports in that module rather than causing
1251 all imports from that module to fail.
1252
Nick Coghlan14ff9942008-07-08 14:21:42 +00001253- Issue #2517: Allow unicode messages in Exceptions again by correctly
1254 bypassing the instance dictionary when looking up __unicode__ on
1255 new-style classes.
1256
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001257- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1258 set to a custom object whose write() method happens to install
1259 another file in sys.stdout.
1260
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001261- Issue #3088: Corrected a race condition in classes derived from
1262 threading.local: the first member set by a thread could be saved in
1263 another thread's dictionary.
1264
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001265- Issue #3004: Minor change to slice.indices(): the start and stop
1266 arguments are now treated identically, making the behaviour easier
1267 to describe and understand. For example, slice(None, -10,
1268 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1269 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1270 10, -1).
1271
Georg Brandl278fc502008-07-19 12:46:12 +00001272- Issue #3219: Calling a function with repeated keyword arguments,
1273 f(a=2, a=23), would not cause a syntax error. This was a regression
1274 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001275
Georg Brandl278fc502008-07-19 12:46:12 +00001276- Issue #2862: Make int and float freelist management consistent with
1277 other freelists. Changes their CompactFreeList apis into
1278 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001283- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1284 api functions without holding the GIL, which could lead to a fatal
1285 error when they failed.
1286
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001287- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1296 ForkingPickler.register() to resolve conflict with ctypes.
1297
Vinay Sajip51e65192008-07-18 09:01:10 +00001298- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001299
Thomas Heller880f5292008-07-15 19:39:38 +00001300- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1301 a valid dlerror() message.

1309
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001310- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001311
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001312- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1313 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001314 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001315 content-length. The problem had been corrected in the 2.4 branch, but never
1316 merged into trunk.
1317
Georg Brandle78fbcc2008-07-05 10:13:36 +00001318- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001331- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1332 handling is now the same as that of other special attributes like __name__).
1333
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001334- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1335 removal in Python 3.0 in favor of urllib2.urlopen().

1791 not called by default for backwards-compatibility reasons. Setting
1792 ``warnings.showwarning()`` to an implementation that lacks support
1793 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001856- Issue #2550: The approach used by client/server code for obtaining
1857 ports to listen on in network-oriented tests has been refined in an
1858 effort to facilitate running multiple instances of the entire
1859 regression test suite in parallel without issue.
1860 test_support.bind_port() has been fixed such that it will always
1861 return a unique port -- which wasn't always the case with the
1862 previous implementation, especially if socket options had been set
1863 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1864 new implementation of bind_port() will actually raise an exception
1865 if it is passed an AF_INET/SOCK_STREAM socket with either the
1866 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1867 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1868 the socket it's been passed. This currently only applies to
1869 Windows. This option prevents any other sockets from binding to the
1870 host/port we've bound to, thus removing the possibility of the
1871 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1872 when a second SOCK_STREAM socket binds and accepts to a host/port
1873 that's already been bound by another socket. The optional preferred
1874 port parameter to bind_port() has been removed. Under no
1875 circumstances should tests be hard coding ports!
1876
1877 test_support.find_unused_port() has also been introduced, which will
1878 pass a temporary socket object to bind_port() in order to obtain an
1879 unused port. The temporary socket object is then closed and
1880 deleted, and the port is returned. This method should only be used
1881 for obtaining an unused port in order to pass to an external program
1882 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1883 a parameter to a server-oriented class that doesn't give you direct
1884 access to the underlying socket used.
1885
1886 Finally, test_support.HOST has been introduced, which should be used
1887 for the host argument of any relevant socket calls (i.e. bind and
1888 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001889
1890 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001891 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

1893 test_asynchat and test_socket_ssl.
1894
Georg Brandl3ee81df2008-05-17 18:14:43 +00001895 It is now possible for multiple instances of the regression test
1896 suite to run in parallel without issue.

2162Core and builtins
2163-----------------
2164
Fred Drakea8ee94b2008-03-01 02:45:07 +00002165- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002166 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002171
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002172- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002173 issue 215555 for a discussion.
2174
Eric Smitha73fbe72008-02-23 03:09:44 +00002175- Added the future_builtins module, which contains hex() and oct().
2176 These are the PEP 3127 version of these functions, designed to be
2177 compatible with the hex() and oct() builtins from Python 3.0. They
2178 differ slightly in their output formats from the existing, unchanged
2179 Python 2.6 builtins. The expected usage of the future_builtins
2180 module is:
2181 from future_builtins import hex, oct
2182
Eric Smith7ef40bf2008-02-20 23:34:22 +00002183- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2184 exponents for exponents with absolute value < 100. Follows C99
2185 standard. This is a change on Windows, which would use 3 digits.
2186 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2187 so that any alterations it does to the resulting string will be
2188 available in stringlib/formatter.h (for float.__format__).
2189
Eric Smith5a3c1352008-02-19 13:21:56 +00002190- Implemented PEP 3101, Advanced String Formatting. This adds a new
2191 builtin format(); a format() method for str and unicode; a
2192 __format__() method to object, str, unicode, int, long, float, and
2193 datetime; the class string.Formatter; and the C API
2194 PyObject_Format().
2195
Georg Brandl3ee81df2008-05-17 18:14:43 +00002196- Fixed several potential crashes, all caused by specially crafted
2197 __del__ methods exploiting objects in temporarily inconsistent
2198 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002199
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002200- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002201 prevent a possible crash: an Abstract Base Class would try to access
2202 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002203

Georg Brandl3ee81df2008-05-17 18:14:43 +00002207- Clear all free lists during a gc.collect() of the highest generation
2208 in order to allow pymalloc to free more arenas. Python may give back
2209 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002210
Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- Issue #2045: Fix an infinite recursion triggered when printing a
2212 subclass of collections.defaultdict, if its default_factory is set
2213 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002214
Christian Heimesf75dbef2008-02-08 00:11:31 +00002215- Fixed a minor memory leak in dictobject.c. The content of the free
2216 list was not freed on interpreter shutdown.
2217
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Limit free list of method and builtin function objects to 256
2219 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002221- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2222 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002223 to compact the internal free lists of pre-allocted ints and floats.
2224
Georg Brandl3ee81df2008-05-17 18:14:43 +00002225- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2226 calls. Python expected the return type int but the fork familie
2227 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002228

Georg Brandl3ee81df2008-05-17 18:14:43 +00002241- Patch #1473257: generator objects gain a gi_code attribute. This is
2242 the same object as the func_code attribute of the function that
2243 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002244
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245- Issue #1920: "while 0" statements were completely removed by the
2246 compiler, even in the presence of an "else" clause, which is
2247 supposed to be run when the condition is false. Now the compiler
2248 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002249
Guido van Rossumeead05f2008-01-24 18:21:02 +00002250- A few crashers fixed: weakref_in_del.py (issue #1377858);

Georg Brandl6caad7d2008-01-26 14:19:22 +00002267- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002268 added.
2269
Christian Heimesc94e2b52008-01-14 04:13:37 +00002270- sys.float_info / PyFloat_GetInfo: The floating point information

Georg Brandl3ee81df2008-05-17 18:14:43 +00002276- Objects/structseq.c: Implemented new structseq representation. The
2277 patch makes structseqs (e.g. the return value of os.stat) more
2278 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002279
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280- Patch #1700288: added a type attribute cache that caches method
2281 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002282
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002283- Bug #1776: __import__() no longer accepts filenames on any platform.
2284 The first parameter to __import__() must be a valid module name.

2289 envvar and sys.dont_write_bytecode attribute. All these can be set
2290 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002291
Georg Brandl3ee81df2008-05-17 18:14:43 +00002292- Improve some exception messages when Windows fails to load an
2293 extension module. Now we get for example '%1 is not a valid Win32
2294 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002295

Christian Heimes0a8143f2007-12-18 23:22:54 +00002301- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002302 and INF. float("nan"), float("inf") and float("-inf") now work on
2303 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002305- Compiler now generates simpler and faster code for dictionary
2306 literals. The oparg for BUILD_MAP now indicates an estimated
2307 dictionary size. There is a new opcode, STORE_MAP, for adding
2308 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002337- Patch #1739468: Directories and zipfiles containing a __main__.py
2338 file can now be directly executed by passing their name to the
2339 interpreter. The directory/zipfile is automatically inserted as the
2340 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002342- Issue #1265: Fix a problem with sys.settrace, if the tracing
2343 function uses a generator expression when at the same time the
2344 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002345
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002346- sets and frozensets now have an isdisjoint() method.

2349
Neal Norwitz44f326e2007-10-05 05:29:17 +00002350- Fix warnings found by the new version of the Coverity checker.
2351
Georg Brandl3ee81df2008-05-17 18:14:43 +00002352- The enumerate() builtin function is no longer bounded to sequences
2353 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2354 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002355
Georg Brandl3ee81df2008-05-17 18:14:43 +00002356- Issue #1686386: Tuple's tp_repr did not take into account the
2357 possibility of having a self-referential tuple, which is possible
2358 from C code. Nor did object's tp_str consider that a type's tp_str
2359 could do something that could lead to an inifinite recursion.
2360 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2361 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002362
Georg Brandl3ee81df2008-05-17 18:14:43 +00002363- Issue #1164: It was possible to trigger deadlock when using the
2364 'print' statement to write to a file since the GIL was not released
2365 as needed. Now PyObject_Print() does the right thing along with
2366 various tp_print implementations of the built-in types and those in
2367 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002368
Georg Brandl3ee81df2008-05-17 18:14:43 +00002369- Issue #1147: Exceptions were directly allowing string exceptions in

2371 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00002375
Brett Cannon1e534b52007-09-07 04:18:30 +00002376- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002377 PyObject_Call() never calling back out to Python code to trigger
2378 recursion depth updates/checks. Required the creation of a static
2379 RuntimeError instance in case normalizing an exception put the
2380 recursion check value past its limit. Fixes crashers
2381 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002382

Neal Norwitz0ac60192007-05-27 04:08:54 +00002396- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002397 __*__ attributes. (Some already existed, e.g., __doc__ and
2398 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002399
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002400- Add -3 option to the interpreter to warn about features that are
2401 deprecated and will be changed/removed in Python 3.0.
2402
Georg Brandl2134e752007-05-21 20:34:16 +00002403- Patch #1686487: you can now pass any mapping after '**' in function
2404 calls.
2405
Collin Winter62903052007-05-18 23:11:24 +00002406- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002407 "except E as target:". This is to provide forwards compatibility
2408 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002409
Brett Cannon229cee22007-05-05 01:34:02 +00002410- Deprecate BaseException.message as per PEP 352.

2414
Vinay Sajip8549ce32007-05-06 17:53:37 +00002415- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002416 setting a plain string, ie don't expand to single letter identifiers.
2417
Raymond Hettinger13936692007-04-11 18:40:58 +00002418- Request #1191699: Slices can now be pickled.
2419
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002420- Request #1193128: str.translate() now allows a None argument for
2421 translations that only remove characters without re-mapping the
2422 remaining characters.
2423
Georg Brandl5cb76c12007-03-21 09:00:39 +00002424- Patch #1682205: a TypeError while unpacking an iterable is no longer
2425 masked by a generic one with the message "unpack non-sequence".
2426
Neal Norwitzaa754b72007-03-21 06:39:48 +00002427- Remove unused file Python/fmod.c.
2428
Guido van Rossum143b5642007-03-23 04:58:42 +00002429- Bug #1683368: The object.__init__() and object.__new__() methods are
2430 now stricter in rejecting excess arguments. The only time when
2431 either allows excess arguments is when it is not overridden and the
2432 other one is. For backwards compatibility, when both are
2433 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002434 warning later). Also, type.__init__() insists on the same signature
2435 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002436
Georg Brandl3ee81df2008-05-17 18:14:43 +00002437- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2438 object to complex using its __complex__() method before falling back
2439 to the __float__() method. Therefore, the functions in the cmath
2440 module now can operate on objects that define a __complex__()
2441 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002442
Georg Brandl3ee81df2008-05-17 18:14:43 +00002443- Patch #1623563: allow __class__ assignment for classes with
2444 __slots__. The old and the new class are still required to have the
2445 same slot names.

2458
Georg Brandl7b9c5552007-03-12 14:30:05 +00002459- Bug #1678647: write a newline after printing an exception in any
2460 case, even when converting the value to a string failed.
2461
Georg Brandl871f1bc2007-03-12 13:17:36 +00002462- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463 its argument, if it exists. If not, it will work like before. This
2464 allows customizing the output of dir() in the presence of a
2465 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002466
Collin Winter276887b2007-03-12 16:11:39 +00002467- Patch #922167: Python no longer segfaults when faced with infinitely
2468 self-recursive reload() calls (as reported by bug #742342).
2469
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470- Patch #1675981: remove unreachable code from ``type.__new__()``

2474 parthensized forms. This means complex(repr(x)) now works instead of
2475 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002476
Georg Brandlaa2321b2007-03-07 00:40:28 +00002477- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002478 makes the filenames the warning module prints much more sensible
2479 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002480

2482 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002483 variable is given, but break into the interactive interpreter just
2484 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002492- Patch #1674228: when assigning a slice (old-style), check for the
2493 sq_ass_slice instead of the sq_slice slot.
2494
Georg Brandl3ee81df2008-05-17 18:14:43 +00002495- When printing an unraisable error, don't print exceptions. before
2496 the name. This duplicates the behavior whening normally printing
2497 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003030 AttributeError instead of an IOError when the server's response
3031 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003032

Georg Brandl3ee81df2008-05-17 18:14:43 +00003037- Patch #1429539: pdb now correctly initializes the __main__ module
3038 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003039 correctly now.

3047
Georg Brandl3ee81df2008-05-17 18:14:43 +00003048- Patch #1530482: add pydoc.render_doc() which returns the

3063
Georg Brandl92a6bae2007-03-13 17:43:32 +00003064- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003065 are set for invalid interpolation sequences that would lead to
3066 errors on reading back those values.

3109 returned string up to the first NUL character.

3120
Georg Brandl3ee81df2008-05-17 18:14:43 +00003121- unittest now verifies more of its assumptions. In particular,
3122 TestCase and TestSuite subclasses (not instances) are no longer
3123 accepted in TestSuite.addTest(). This should cause no
3124 incompatibility since it never made sense with ordinary subclasses
3125 -- the failure just occurred later, with a more cumbersome
3126 exception.

3136
Georg Brandl3ee81df2008-05-17 18:14:43 +00003137- Patch #1673619: setup.py identifies extension modules it doesn't

3497 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3498 silently miscode subclasses of those types. Now, it raises a
3499 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003514- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003515 time so that opening a database previously created with the DB_DUP
3516 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3517 opens. Specifically: dictionary assignment to a DB object will
3518 replace all values for a given key when the database allows
3519 duplicate values. DB users should use DB.put(k, v) when they want
3520 to store duplicates; not DB[k] = v.

3527 characters with ASCII value less than 32. Also, it correctly quotes
3528 dots only if they occur on a single line, as opposed to the previous
3529 behavior of quoting dots if they are the second character of any
3530 line.

3876 of w# format code incorrectly truncated the length to an int, even
3877 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3878 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003908- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3909 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
