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
Antoine Pitrou789be0c2009-04-02 21:18:34 +000015- Issue #2396: the memoryview object was backported from Python 3.1.
16
Georg Brandld3f03fa2009-04-02 18:09:04 +000017- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
18 when hitting the recursion limit under certain circumstances.
19
Brett Cannon15ba4da2009-04-01 18:03:59 +000020- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
21
Ronald Oussorene0154ed2009-03-30 23:10:35 +000022- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
23 the end sys.path, for compatibility with the system install of Python.
24
Antoine Pitrouf8387af2009-03-23 18:41:45 +000025- Issue #4688: Add a heuristic so that tuples and dicts containing only
26 untrackable objects are not tracked by the garbage collector. This can
27 reduce the size of collections and therefore the garbage collection overhead
28 on long-running programs, depending on their particular use of datatypes.
29
Mark Dickinson0b666bf2009-03-23 18:25:13 +000030- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
31 improve its performance. Long divisions and remainder operations
32 are now between 50% and 150% faster.
33
Mark Dickinsonefc82f72009-03-20 15:51:55 +000034- Issue #4258: Make it possible to use base 2**30 instead of base
35 2**15 for the internal representation of integers, for performance
36 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
37 --enable-big-digits option to configure, which overrides the
38 default. Add sys.long_info structseq to provide information about
39 the internal format.
40
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000041- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
42 result traceback.__members__ no longer exists.)
43
Mark Dickinson6b265f12009-03-18 16:07:26 +000044- Issue #4474: PyUnicode_FromWideChar now converts characters outside
45 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
46 and sizeof(Py_UNICODE) == 2.
47
Eric Smith6f42edb2009-03-14 11:57:26 +000048- Issue #5237: Allow auto-numbered fields in str.format(). For
49 example: '{} {}'.format(1, 2) == '1 2'.
50
Brett Cannon6c4cff02009-03-11 04:51:06 +000051- Issue #3652: Make the 'line' argument for warnings.showwarning() a
52 requirement. Means the DeprecationWarning from Python 2.6 can go away.
53
Eric Smithe9fb6862009-02-20 14:02:36 +000054- Issue #5247: Improve error message when unknown format codes are
55 used when using str.format() with str, unicode, long, int, and
56 float arguments.
57
Raymond Hettinger08259e82009-02-18 23:10:19 +000058- Running Python with the -3 option now also warns about classic division
59 for ints and longs.
60
Mark Dickinson2ffb26f2009-02-15 10:13:41 +000061- Issue #5260: Long integers now consume less memory: average
62 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
63 on a 64-bit system.
64
Antoine Pitrou76a4b892009-02-13 13:52:33 +000065- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
66 rotating the object pointer by 4 bits to the right.
67
Mark Dickinsonc97c9092009-02-09 14:18:43 +000068- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
69 it now forces its argument to double before testing for infinity.
70
Benjamin Petersone18ef192009-01-20 14:21:16 +000071- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
72
Raymond Hettingerb5163702009-02-02 21:50:13 +000073- Issue 1242657: the __len__() and __length_hint__() calls in several tools
74 were suppressing all exceptions. These include list(), filter(), map(),
75 zip(), and bytearray().
76
Benjamin Peterson596d3062009-01-19 15:42:23 +000077- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
78 functions.
79
Benjamin Peterson5848d1f2009-01-19 00:08:08 +000080- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
81 OSError.
82
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +000083- Issue #4807: Port the _winreg module to Windows CE.
84
Antoine Pitrouc2f02212009-01-13 23:13:52 +000085- Issue #4935: The overflow checking code in the expandtabs() method common
86 to str, bytes and bytearray could be optimized away by the compiler, letting
87 the interpreter segfault instead of raising an error.
88
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +000089- Issue #3720: Fix a crash when an iterator modifies its class and removes its
90 __next__ method.
91
Martin v. Löwise3422fa2009-01-12 08:11:24 +000092- Issue #4893: Use NT threading on CE.
93
Martin v. Löwis1b3bef22009-01-12 07:57:11 +000094- Issue #4915: Port sysmodule to Windows CE.
95
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +000096- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
97 collecting the oldest generation) so that allocating lots of objects without
98 destroying them does not show quadratic performance. Based on a proposal by
99 Martin von Löwis at
100 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
101
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000102- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
103
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000104- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
105 an existing .py counterpart, override the co_filename attributes of all
106 code objects if the original filename is obsolete (which can happen if the
107 file has been renamed, moved, or if it is accessed through different paths).
108 Patch by Ziga Seilnacht and Jean-Paul Calderone.
109
Martin v. Löwis5344c992009-01-02 20:32:55 +0000110- Issue #4075: Use OutputDebugStringW in Py_FatalError.
111
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000112- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
113 file with `str' filename on Windows.
114
Antoine Pitrouaa687902009-01-01 14:11:22 +0000115- Issue #3680: Reference cycles created through a dict, set or deque iterator
116 did not get collected.
117
Nick Coghlan180e4002008-12-30 01:18:48 +0000118- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
119 where the tp_hash and tp_dict slots are both NULL.
120
Benjamin Peterson7af65562008-12-29 17:56:58 +0000121- Issue #4764: With io.open, IOError.filename is set when trying to open a
122 directory on POSIX systems.
123
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000124- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
125 systems.
126
Georg Brandl6425a2f2008-12-28 11:54:53 +0000127- Issue #4759: None is now allowed as the first argument of
128 bytearray.translate(). It was always allowed for bytes.translate().
129
Skip Montanarof205c132008-12-23 03:30:15 +0000130- Added test case to ensure attempts to read from a file opened for writing
131 fail.
132
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000133- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
134 print elapsed times, not only when some objects are uncollectable /
135 unreachable. Original patch by Neil Schemenauer.
136
Mark Dickinson1a707982008-12-17 16:14:37 +0000137- Issue #3439: Add a bit_length method to int and long.
138

143 context manager returns a value that cannot be converted to a bool.
144
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000145- Issue #4597: Fixed several opcodes that weren't always propagating
146 exceptions.
147
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000148- Issue #4445: Replace "sizeof(PyStringObject)" with
149 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
150 str instances. On a typical machine this saves 3 bytes of memory
151 (on average) per string allocation.
152
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000153- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
154 interpreter to abort ("Fatal Python error: Could not reset the stack!")
155 instead of throwing a MemoryError.
156
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000157- Issue #3689: The list reversed iterator now supports __length_hint__
158 instead of __len__. Behavior now matches other reversed iterators.
159
Benjamin Petersonc078f922008-11-21 22:27:24 +0000160- Issue #4367: Python would segfault during compiling when the unicodedata
161 module couldn't be imported and \N escapes were present.
162
Vinay Sajip213faca2008-12-03 23:22:58 +0000163- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000164 method on file objects with closefd=False. The file descriptor is still
165 kept open but the file object behaves like a closed file. The ``FileIO``
166 object also got a new readonly attribute ``closefd``.
167
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000168- Issue #4348: Some bytearray methods returned that didn't cause any change to
169 the bytearray, returned the same bytearray instead of a copy.
170
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000171- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
172

176
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000177- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
178 exec statement.
179
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000180- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
181 method does not return iterators for the 4th and 5th items.
182
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000183- Issue #4209: Enabling unicode_literals and the print_function in the same
184 __future__ import didn't work.
185
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000186- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000187 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000188
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000189- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
190 returned a path longer than MAX_PATH. (But It's doubtful this code path is
191 really executed because I cannot move to such directory on win2k)
192
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000193- Issue #4069: When set.remove(element) is used with a set element, the element
194 is temporarily replaced with an equivalent frozenset. But the eventual
195 KeyError would always report the empty frozenset([]) as the missing key. Now
196 it correctly refers to the initial element.
197
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000198- Issue #4509: Various issues surrounding resize of bytearray objects to
199 which there are buffer exports.
200
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000201- Issue #4748: Lambda generators no longer return a value.

208 short file names.
209
Matthias Klose0610e082009-04-05 12:43:08 +0000210- Py_DECREF: Add `do { ... } while (0)' to avoid compiler warnings.

229 to note the limitation
230
Michael Foord345b2fe2009-04-02 03:20:38 +0000231- unittest.assertNotEqual() now uses the inequality operator (!=) instead
232 of the equality operator.
233
234- Issue #5663: better failure messages for unittest asserts. Default assertTrue
235 and assertFalse messages are now useful. TestCase has a longMessage attribute.
236 This defaults to False, but if set to True useful error messages are shown in
237 addition to explicit messages passed to assert methods.
238
Jesse Nollerb502bc72009-04-02 02:32:55 +0000239- Issue #3110: Add additional protect around SEM_VALUE_MAX for multiprocessing

283 output compared to previous Python versions.
284
Benjamin Peterson692428e2009-03-23 21:50:21 +0000285- Issue #1034053: unittest now supports skipping tests and expected failures.
286
Gregory P. Smith28399852009-03-31 16:54:10 +0000287- The unittest.TestCase.assertRaises() method now returns a context manager when
288 not given a callable so that code to be tested can be written inline using
289 a with statement.
290
291- The unittest.TestCase.assertEqual() now displays the differences in lists,
292 tuples, dicts and sets on failure. Many new handy type and comparison
293 specific assert* methods have been added that fail with error messages
294 actually useful for debugging. Contributed in part by Google. [Issue #2578]

298 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
299 partial bzip2 compressed data.
300
Benjamin Petersonb364bfe2009-03-22 17:45:11 +0000301- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000900 was correctly parsed but parsing of subsequent arguments failed.
901
Vinay Sajip35e3b032008-09-01 14:33:59 +0000902- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000903 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
904 mechanism. In the process, fix a bug where isinstance() and issubclass(),
905 when given a tuple of classes as second argument, were looking up
906 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
907 type object.
908
Neal Norwitz18aa3882008-08-24 05:04:52 +0000909- Fix crashes on memory allocation failure found with failmalloc.

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

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001046What's New in Python 2.6 beta 3?
1047================================
1048
Barry Warsaw07a4a382008-08-21 01:15:08 +00001049*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001050
1051Core and Builtins
1052-----------------
1053
Guido van Rossumf8402962008-08-20 15:01:50 +00001054- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1055 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1056 extensions do not automatically benefit from the class attribute
1057 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1058 to their tp_flags field if they care. This is a backwards
1059 compatibility feature; in 3.0, all types will use the cache by
1060 default.
1061
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001062- Keyword arguments can now follow starred arguments. (``f(a, *args,
1063 keyword=23)`` is now valid syntax.)
1064
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001065- ctypes function pointers that are COM methods have a boolean True
1066 value again.
1067
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001068- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1069 by denying s# to parse objects that have a releasebuffer procedure,
1070 and introducing s*.
1071
Georg Brandl1e13ea92008-08-11 09:07:59 +00001072- Issue #3537: Fix an assertion failure when an empty but presized dict
1073 object was stored in the freelist.
1074
Mark Dickinsonb6467572008-08-04 21:30:09 +00001075- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1076 ValueError consistently across platforms.
1077
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001078- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1079 (64bit Unix, for example), unichr() would truncate its argument and return
1080 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1081
Neal Norwitze7d8be82008-07-31 17:17:14 +00001082- Apply security patches from Apple.
1083
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001084- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1085 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1086
Antoine Pitrou92f82162008-07-25 22:22:08 +00001087- Issue #1819: function calls with several named parameters are now on
1088 average 35% faster (as measured by pybench).
1089
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001090- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1091 the python debugger steps into a class statement: the free variables (local
1092 variables defined in an outer scope) would be deleted from the outer scope.
1093
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001094- Issue #2620: Overflow checking when allocating or reallocating memory
1095 was not always being done properly in some python types and extension
1096 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1097 all been updated to perform better checks and places in the code that
1098 would previously leak memory on the error path when such an allocation
1099 failed have been fixed.

1103
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001104- Issue #3612: Added some missing basic types in ctypes.wintypes.
1105
Benjamin Petersone977ad42008-08-20 01:42:01 +00001106- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1107 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1108
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001109- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1110 version reported by these tools does not necessarily follow the python
1111 version numbering scheme, so the module is less strict when parsing it.
1112
Nick Coghlanf70385a2008-08-18 12:42:46 +00001113- Issue #2235: Added Py3k warnings for types which will become unhashable
1114 under the stricter __hash__ inheritance rules in 3.0. Several types
1115 which did not meet the rules for hash invariants and were already
1116 unhashable in 3.0 have now been explicitly flagged as unhashable in
1117 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1118 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1119
Brett Cannon88f801d2008-08-18 00:46:22 +00001120- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1121 imported into the module but exposed as part of the module's API.
1122
Brett Cannon7b96f072008-08-18 00:41:11 +00001123- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1124
Brett Cannon46225e72008-08-18 00:36:52 +00001125- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001127- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1128
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001129- Issue #3575: Incremental decoder's decode function now takes bytearray
1130 by using 's*' instead of 't#'.
1131
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001132- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001133 fails unicode conversion on 2nd parameter. (windows only)
1134
Facundo Batista94f243a2008-08-17 03:38:39 +00001135- Issue 2464. urllib2 now supports a malformation in the URL received
1136 in a redirect.
1137
Brett Cannonabe423e2008-08-16 21:47:07 +00001138- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001139 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001140
Facundo Batistaeb90b782008-08-16 14:44:07 +00001141- Issue #2776: fixed small issue when handling an URL with double slash
1142 after a 302 response in the case of not going through a proxy.
1143
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001144- Issue #2676: in the email package, content-type parsing was hanging on
1145 pathological input because of quadratic or exponential behaviour of a
1146 regular expression.
1147
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001148- Issue #3476: binary buffered reading through the new "io" library is now
1149 thread-safe.
1150
Brett Cannonbf3157b2008-08-14 05:00:03 +00001151- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1152 since mimetools itself is deprecated. Because modules are cached, all
1153 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1154
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001155- Issue #3134: shutil referenced undefined WindowsError symbol.
1156
Robert Schuppenies14646332008-08-10 11:01:53 +00001157- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1158 menu entries were not deleted.
1159
Brett Cannon83e81842008-08-09 23:30:55 +00001160- Copied the implementation of reduce() to _functools.reduce() to have a
1161 version that did not raise a DeprecationWarning under -3.
1162
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001163- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1164 a MemoryError rather than silently stop the iteration.
1165
Guido van Rossum59ce9012008-08-09 14:55:34 +00001166- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1167 to _sre.compile() will now be rejected. This should not affect anybody
1168 since the re.compile() function never generates invalid re-bytecode.
1169
Skip Montanaroa032bf42008-08-08 22:52:51 +00001170- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1171 upon first access it can be automatically initialized from the csv file if
1172 it wasn't initialized during instantiation.
1173
Brett Cannon3aa2a492008-08-06 22:28:09 +00001174- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1175 the reload() built-in has been removed.
1176
Brett Cannon7e30b672008-08-04 21:52:25 +00001177- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001178 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1242
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001243*Release date: 17-Jul-2008*

1246-----------------
1247
Georg Brandl3e483f62008-07-16 22:57:41 +00001248- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1249 its methods now allow for items objects that can be converted to
1250 an integer using operator.index().
1251
Mark Dickinson64b7e502008-07-16 09:40:03 +00001252- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1253 produced a ValueError instead of giving the correct float.
1254
Eric Smitha5fa5a22008-07-16 00:11:49 +00001255- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1256 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1257
Mark Dickinson7103aa42008-07-15 19:08:33 +00001258- Issue #3008: the float type has a new instance method 'float.hex'
1259 and a new class method 'float.fromhex' to convert floating-point
1260 numbers to and from hexadecimal strings, respectively.
1261
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001262- Issue #2235: __hash__ is once again inherited by default. To allow
1263 collections.Hashable to remain meaningful in the presence of the
1264 default hash implementation (object.__hash__), it is now possible
1265 to explicit block inheritance of hash by setting __hash__=None at
1266 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1267 level.
1268
Nick Coghlanb028f502008-07-13 14:52:36 +00001269- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1270 the parent module cannot be found while performing an absolute import.
1271 This means that an incorrectly defined __package__ attribute will
1272 now only prevent relative imports in that module rather than causing
1273 all imports from that module to fail.
1274
Nick Coghlan14ff9942008-07-08 14:21:42 +00001275- Issue #2517: Allow unicode messages in Exceptions again by correctly

1285 another thread's dictionary.
1286
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001287- Issue #3004: Minor change to slice.indices(): the start and stop
1288 arguments are now treated identically, making the behaviour easier
1289 to describe and understand. For example, slice(None, -10,
1290 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1291 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1292 10, -1).
1293
Georg Brandl278fc502008-07-19 12:46:12 +00001294- Issue #3219: Calling a function with repeated keyword arguments,
1295 f(a=2, a=23), would not cause a syntax error. This was a regression
1296 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001334- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1335 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001336 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001337 content-length. The problem had been corrected in the 2.4 branch, but never
1338 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001353- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl74a1dea2008-05-28 11:21:39 +00001764- Add ``PyType_Modified()`` as a public API to clear the type cache.
1765
1766- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00001767
1768- The PyString functions have been renamed to PyBytes. A batch of
1769 defines were added so that the linker still sees the original
1770 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001808- Issue #1631171: Re-implement the 'warnings' module in C (the
1809 original Python code has been kept as backup). This will allow for
1810 using the 'warning's machinery in such places as the parser where
1811 use of pure Python code is not possible. Both the ``showarning()``
1812 and ``formatwarning()`` gain an optional 'line' argument which is
1813 not called by default for backwards-compatibility reasons. Setting
1814 ``warnings.showwarning()`` to an implementation that lacks support
1815 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001840- The getpass module has been improved on Unix. It now uses /dev/tty
1841 by default and uses stderr instead of stdout. A GetPassWarning is
1842 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001857- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001858 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001878- Issue #2550: The approach used by client/server code for obtaining
1879 ports to listen on in network-oriented tests has been refined in an
1880 effort to facilitate running multiple instances of the entire
1881 regression test suite in parallel without issue.
1882 test_support.bind_port() has been fixed such that it will always
1883 return a unique port -- which wasn't always the case with the
1884 previous implementation, especially if socket options had been set
1885 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1886 new implementation of bind_port() will actually raise an exception
1887 if it is passed an AF_INET/SOCK_STREAM socket with either the
1888 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1889 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1890 the socket it's been passed. This currently only applies to
1891 Windows. This option prevents any other sockets from binding to the
1892 host/port we've bound to, thus removing the possibility of the
1893 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1894 when a second SOCK_STREAM socket binds and accepts to a host/port
1895 that's already been bound by another socket. The optional preferred
1896 port parameter to bind_port() has been removed. Under no
1897 circumstances should tests be hard coding ports!
1898
1899 test_support.find_unused_port() has also been introduced, which will
1900 pass a temporary socket object to bind_port() in order to obtain an
1901 unused port. The temporary socket object is then closed and
1902 deleted, and the port is returned. This method should only be used
1903 for obtaining an unused port in order to pass to an external program
1904 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1905 a parameter to a server-oriented class that doesn't give you direct
1906 access to the underlying socket used.
1907
1908 Finally, test_support.HOST has been introduced, which should be used
1909 for the host argument of any relevant socket calls (i.e. bind and
1910 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001911
1912 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001913 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001914 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1915 test_asynchat and test_socket_ssl.
1916
Georg Brandl3ee81df2008-05-17 18:14:43 +00001917 It is now possible for multiple instances of the regression test
1918 suite to run in parallel without issue.

2184Core and builtins
2185-----------------
2186
Fred Drakea8ee94b2008-03-01 02:45:07 +00002187- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002188 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002190- Issue #2067: file.__exit__() now calls subclasses' close() method.
2191
2192- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002193
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002194- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002195 issue 215555 for a discussion.
2196
Eric Smitha73fbe72008-02-23 03:09:44 +00002197- Added the future_builtins module, which contains hex() and oct().
2198 These are the PEP 3127 version of these functions, designed to be
2199 compatible with the hex() and oct() builtins from Python 3.0. They
2200 differ slightly in their output formats from the existing, unchanged
2201 Python 2.6 builtins. The expected usage of the future_builtins
2202 module is:
2203 from future_builtins import hex, oct
2204
Eric Smith7ef40bf2008-02-20 23:34:22 +00002205- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2206 exponents for exponents with absolute value < 100. Follows C99
2207 standard. This is a change on Windows, which would use 3 digits.
2208 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2209 so that any alterations it does to the resulting string will be
2210 available in stringlib/formatter.h (for float.__format__).
2211
Eric Smith5a3c1352008-02-19 13:21:56 +00002212- Implemented PEP 3101, Advanced String Formatting. This adds a new
2213 builtin format(); a format() method for str and unicode; a
2214 __format__() method to object, str, unicode, int, long, float, and
2215 datetime; the class string.Formatter; and the C API
2216 PyObject_Format().
2217
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Fixed several potential crashes, all caused by specially crafted
2219 __del__ methods exploiting objects in temporarily inconsistent
2220 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002221
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002222- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002223 prevent a possible crash: an Abstract Base Class would try to access
2224 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002225

Georg Brandl3ee81df2008-05-17 18:14:43 +00002229- Clear all free lists during a gc.collect() of the highest generation
2230 in order to allow pymalloc to free more arenas. Python may give back
2231 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002232
Georg Brandl3ee81df2008-05-17 18:14:43 +00002233- Issue #2045: Fix an infinite recursion triggered when printing a
2234 subclass of collections.defaultdict, if its default_factory is set
2235 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002236
Christian Heimesf75dbef2008-02-08 00:11:31 +00002237- Fixed a minor memory leak in dictobject.c. The content of the free
2238 list was not freed on interpreter shutdown.
2239
Georg Brandl3ee81df2008-05-17 18:14:43 +00002240- Limit free list of method and builtin function objects to 256
2241 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002242
Georg Brandl3ee81df2008-05-17 18:14:43 +00002243- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2244 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002245 to compact the internal free lists of pre-allocted ints and floats.
2246
Georg Brandl3ee81df2008-05-17 18:14:43 +00002247- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2248 calls. Python expected the return type int but the fork familie
2249 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002250
Georg Brandl3ee81df2008-05-17 18:14:43 +00002251- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002263- Patch #1473257: generator objects gain a gi_code attribute. This is
2264 the same object as the func_code attribute of the function that
2265 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002266
Georg Brandl3ee81df2008-05-17 18:14:43 +00002267- Issue #1920: "while 0" statements were completely removed by the
2268 compiler, even in the presence of an "else" clause, which is
2269 supposed to be run when the condition is false. Now the compiler
2270 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002271
Guido van Rossumeead05f2008-01-24 18:21:02 +00002272- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002276- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002277 suppressed while an extension is loaded by calling SetErrorMode in
2278 dynload_win.c. The error is still reported properly.
2279
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002281 several extension methods and modules do not work without unicode
2282 support.
2283
Georg Brandl26543b12008-01-21 18:36:51 +00002284- Issue #1882: when compiling code from a string, encoding cookies in the
2285 second line of code were not always recognized correctly.
2286
Georg Brandl14404b62008-01-19 19:27:05 +00002287- Issue #1679: "0x" was taken as a valid integer literal.
2288
Georg Brandl6caad7d2008-01-26 14:19:22 +00002289- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002290 added.
2291
Christian Heimesc94e2b52008-01-14 04:13:37 +00002292- sys.float_info / PyFloat_GetInfo: The floating point information
2293 object was converted from a dict to a specialized structseq object.
2294
Georg Brandl3ee81df2008-05-17 18:14:43 +00002295- Patch #1816: Added sys.flags structseq. It exposes the status of
2296 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002297
Georg Brandl3ee81df2008-05-17 18:14:43 +00002298- Objects/structseq.c: Implemented new structseq representation. The
2299 patch makes structseqs (e.g. the return value of os.stat) more
2300 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002301
Georg Brandl3ee81df2008-05-17 18:14:43 +00002302- Patch #1700288: added a type attribute cache that caches method
2303 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002304
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002305- Bug #1776: __import__() no longer accepts filenames on any platform.
2306 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002307
Georg Brandlaed6c662008-01-07 17:25:53 +00002308- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2309
Georg Brandl3ee81df2008-05-17 18:14:43 +00002310- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2311 envvar and sys.dont_write_bytecode attribute. All these can be set
2312 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002313
Georg Brandl3ee81df2008-05-17 18:14:43 +00002314- Improve some exception messages when Windows fails to load an
2315 extension module. Now we get for example '%1 is not a valid Win32
2316 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002317
Georg Brandl3ee81df2008-05-17 18:14:43 +00002318- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002320- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2321 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002322
Christian Heimes0a8143f2007-12-18 23:22:54 +00002323- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002324 and INF. float("nan"), float("inf") and float("-inf") now work on
2325 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002326
Georg Brandl3ee81df2008-05-17 18:14:43 +00002327- Compiler now generates simpler and faster code for dictionary
2328 literals. The oparg for BUILD_MAP now indicates an estimated
2329 dictionary size. There is a new opcode, STORE_MAP, for adding
2330 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002331
Georg Brandl3ee81df2008-05-17 18:14:43 +00002332- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002334- Issue #1620: New property decorator syntax was modifying the
2335 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002336
Georg Brandl3ee81df2008-05-17 18:14:43 +00002337- Issue #1538: Avoid copying string in split/rsplit if the split char
2338 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002339
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002340- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002341 SystemError.
2342
Nick Coghlanef01d822007-12-03 12:55:17 +00002343- PEP 366: Allow explicit relative imports when executing modules

2348 running, and if the deallocation of its frames somehow calls the
2349 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002350

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002354 attribute of an empty cell object.
2355
Georg Brandl3ee81df2008-05-17 18:14:43 +00002356- Issue #1460: The utf-7 incremental decoder did not accept truncated
2357 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002358
Georg Brandl3ee81df2008-05-17 18:14:43 +00002359- Patch #1739468: Directories and zipfiles containing a __main__.py
2360 file can now be directly executed by passing their name to the
2361 interpreter. The directory/zipfile is automatically inserted as the
2362 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002363
Georg Brandl3ee81df2008-05-17 18:14:43 +00002364- Issue #1265: Fix a problem with sys.settrace, if the tracing
2365 function uses a generator expression when at the same time the
2366 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002367
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002368- sets and frozensets now have an isdisjoint() method.
2369
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002370- optimize the performance of builtin.sum().
2371
Neal Norwitz44f326e2007-10-05 05:29:17 +00002372- Fix warnings found by the new version of the Coverity checker.
2373
Georg Brandl3ee81df2008-05-17 18:14:43 +00002374- The enumerate() builtin function is no longer bounded to sequences
2375 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2376 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002377
Georg Brandl3ee81df2008-05-17 18:14:43 +00002378- Issue #1686386: Tuple's tp_repr did not take into account the
2379 possibility of having a self-referential tuple, which is possible
2380 from C code. Nor did object's tp_str consider that a type's tp_str
2381 could do something that could lead to an inifinite recursion.
2382 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2383 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002384
Georg Brandl3ee81df2008-05-17 18:14:43 +00002385- Issue #1164: It was possible to trigger deadlock when using the
2386 'print' statement to write to a file since the GIL was not released
2387 as needed. Now PyObject_Print() does the right thing along with
2388 various tp_print implementations of the built-in types and those in
2389 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002390
Georg Brandl3ee81df2008-05-17 18:14:43 +00002391- Issue #1147: Exceptions were directly allowing string exceptions in
2392 their throw() method even though string exceptions no longer
2393 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002394
Georg Brandl3ee81df2008-05-17 18:14:43 +00002395- Issue #1096: Prevent a segfault from getting the repr of a very
2396 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002397
Brett Cannon1e534b52007-09-07 04:18:30 +00002398- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002399 PyObject_Call() never calling back out to Python code to trigger
2400 recursion depth updates/checks. Required the creation of a static
2401 RuntimeError instance in case normalizing an exception put the
2402 recursion check value past its limit. Fixes crashers
2403 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002404
Georg Brandl3ee81df2008-05-17 18:14:43 +00002405- Patch #1031213: Decode source line in SyntaxErrors back to its
2406 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00002407
Georg Brandl7c3b50d2007-07-12 08:38:00 +00002408- Patch #1673759: add a missing overflow check when formatting floats
2409 with %G.
2410
Georg Brandl3ee81df2008-05-17 18:14:43 +00002411- Prevent expandtabs() on string and unicode objects from causing a
2412 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002413

Georg Brandl3ee81df2008-05-17 18:14:43 +00002416- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00002417
Neal Norwitz0ac60192007-05-27 04:08:54 +00002418- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002419 __*__ attributes. (Some already existed, e.g., __doc__ and
2420 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002421
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002422- Add -3 option to the interpreter to warn about features that are
2423 deprecated and will be changed/removed in Python 3.0.
2424
Georg Brandl2134e752007-05-21 20:34:16 +00002425- Patch #1686487: you can now pass any mapping after '**' in function
2426 calls.
2427
Collin Winter62903052007-05-18 23:11:24 +00002428- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002429 "except E as target:". This is to provide forwards compatibility
2430 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002431
Brett Cannon229cee22007-05-05 01:34:02 +00002432- Deprecate BaseException.message as per PEP 352.
2433
Georg Brandl3ee81df2008-05-17 18:14:43 +00002434- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002435 inherited from a builtin base.
2436
Vinay Sajip8549ce32007-05-06 17:53:37 +00002437- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002438 setting a plain string, ie don't expand to single letter identifiers.
2439
Raymond Hettinger13936692007-04-11 18:40:58 +00002440- Request #1191699: Slices can now be pickled.
2441
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002442- Request #1193128: str.translate() now allows a None argument for
2443 translations that only remove characters without re-mapping the
2444 remaining characters.
2445
Georg Brandl5cb76c12007-03-21 09:00:39 +00002446- Patch #1682205: a TypeError while unpacking an iterable is no longer
2447 masked by a generic one with the message "unpack non-sequence".
2448
Neal Norwitzaa754b72007-03-21 06:39:48 +00002449- Remove unused file Python/fmod.c.
2450
Guido van Rossum143b5642007-03-23 04:58:42 +00002451- Bug #1683368: The object.__init__() and object.__new__() methods are
2452 now stricter in rejecting excess arguments. The only time when
2453 either allows excess arguments is when it is not overridden and the
2454 other one is. For backwards compatibility, when both are
2455 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002456 warning later). Also, type.__init__() insists on the same signature
2457 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002458
Georg Brandl3ee81df2008-05-17 18:14:43 +00002459- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2460 object to complex using its __complex__() method before falling back
2461 to the __float__() method. Therefore, the functions in the cmath
2462 module now can operate on objects that define a __complex__()
2463 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002464
Georg Brandl3ee81df2008-05-17 18:14:43 +00002465- Patch #1623563: allow __class__ assignment for classes with
2466 __slots__. The old and the new class are still required to have the
2467 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002468
Georg Brandl3ee81df2008-05-17 18:14:43 +00002469- Patch #1642547: Fix an error/crash when encountering syntax errors
2470 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002472- Patch #1462488: Python no longer segfaults when
2473 ``object.__reduce_ex__()`` is called with an object that is faking
2474 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002475
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476- Patch #1680015: Don't modify __slots__ tuple if it contains an
2477 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00002479- Patch #1444529: the builtin compile() now accepts keyword arguments.
2480
Georg Brandl7b9c5552007-03-12 14:30:05 +00002481- Bug #1678647: write a newline after printing an exception in any
2482 case, even when converting the value to a string failed.
2483
Georg Brandl871f1bc2007-03-12 13:17:36 +00002484- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002485 its argument, if it exists. If not, it will work like before. This
2486 allows customizing the output of dir() in the presence of a
2487 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002488
Collin Winter276887b2007-03-12 16:11:39 +00002489- Patch #922167: Python no longer segfaults when faced with infinitely
2490 self-recursive reload() calls (as reported by bug #742342).
2491
Georg Brandl3ee81df2008-05-17 18:14:43 +00002492- Patch #1675981: remove unreachable code from ``type.__new__()``
2493 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002495- Patch #1491866: change the complex() constructor to allow
2496 parthensized forms. This means complex(repr(x)) now works instead of
2497 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002498
Georg Brandlaa2321b2007-03-07 00:40:28 +00002499- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002500 makes the filenames the warning module prints much more sensible
2501 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002502
Georg Brandl49aafc92007-03-07 00:34:46 +00002503- Variant of patch #697613: don't exit the interpreter on a SystemExit
2504 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002505 variable is given, but break into the interactive interpreter just
2506 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00002507
Georg Brandl3ee81df2008-05-17 18:14:43 +00002508- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002511- Bug #1674503: close the file opened by execfile() in an error
2512 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002513
Georg Brandl0fca97a2007-03-05 22:28:08 +00002514- Patch #1674228: when assigning a slice (old-style), check for the

3007 (as opposed to the command line) will now write file names ending in
3008 ".cpp" too.
3009
Facundo Batistad918a652007-04-24 13:54:38 +00003010- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003011 the client's request was successfully received, understood, and
3012 accepted. Now in these cases no error is raised in urllib (issue
3013 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003021- Added a timeout parameter to the constructor of other protocols
3022 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3023 work started with create_connection() and timeout in httplib, and
3024 closes patch #723312.
3025
Vinay Sajip8549ce32007-05-06 17:53:37 +00003026- Patch #1676823: Added create_connection() to socket.py, which may be
3027 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003028 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003029
Martin v. Löwis0af33882007-03-23 13:27:15 +00003030- Bug #978833: Revert r50844, as it broke _socketobject.dup.

3050
Georg Brandlf66b6032007-03-14 08:27:52 +00003051- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003052 AttributeError instead of an IOError when the server's response
3053 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003054
Georg Brandl3ee81df2008-05-17 18:14:43 +00003055- Patch #957650: "%var%" environment variable references are now
3056 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00003059- Patch #1429539: pdb now correctly initializes the __main__ module
3060 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003061 correctly now.
3062
Georg Brandlbad6f192007-03-13 21:32:56 +00003063- The nonobvious commands.getstatus() function is now deprecated.

3069
Georg Brandl3ee81df2008-05-17 18:14:43 +00003070- Patch #1530482: add pydoc.render_doc() which returns the
3071 documentation for a thing instead of paging it to stdout, which

Georg Brandl9e6b4702007-03-13 18:15:41 +00003083- Patch #1581073: add a flag to textwrap that prevents the dropping of
3084 whitespace while wrapping.
3085
Georg Brandl92a6bae2007-03-13 17:43:32 +00003086- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003087 are set for invalid interpolation sequences that would lead to
3088 errors on reading back those values.

3131 returned string up to the first NUL character.

3142
Georg Brandl3ee81df2008-05-17 18:14:43 +00003143- unittest now verifies more of its assumptions. In particular,
3144 TestCase and TestSuite subclasses (not instances) are no longer
3145 accepted in TestSuite.addTest(). This should cause no
3146 incompatibility since it never made sense with ordinary subclasses
3147 -- the failure just occurred later, with a more cumbersome
3148 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003537 time so that opening a database previously created with the DB_DUP
3538 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3539 opens. Specifically: dictionary assignment to a DB object will
3540 replace all values for a given key when the database allows
3541 duplicate values. DB users should use DB.put(k, v) when they want
3542 to store duplicates; not DB[k] = v.

3549 characters with ASCII value less than 32. Also, it correctly quotes
3550 dots only if they occur on a single line, as opposed to the previous
3551 behavior of quoting dots if they are the second character of any
3552 line.
