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
Georg Brandld3f03fa2009-04-02 18:09:04 +000015- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
16 when hitting the recursion limit under certain circumstances.
17
Brett Cannon15ba4da2009-04-01 18:03:59 +000018- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
19
Ronald Oussorene0154ed2009-03-30 23:10:35 +000020- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
21 the end sys.path, for compatibility with the system install of Python.
22
Antoine Pitrouf8387af2009-03-23 18:41:45 +000023- Issue #4688: Add a heuristic so that tuples and dicts containing only
24 untrackable objects are not tracked by the garbage collector. This can
25 reduce the size of collections and therefore the garbage collection overhead
26 on long-running programs, depending on their particular use of datatypes.
27
Mark Dickinson0b666bf2009-03-23 18:25:13 +000028- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
29 improve its performance. Long divisions and remainder operations
30 are now between 50% and 150% faster.
31
Mark Dickinsonefc82f72009-03-20 15:51:55 +000032- Issue #4258: Make it possible to use base 2**30 instead of base
33 2**15 for the internal representation of integers, for performance
34 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
35 --enable-big-digits option to configure, which overrides the
36 default. Add sys.long_info structseq to provide information about
37 the internal format.
38
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000039- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
40 result traceback.__members__ no longer exists.)
41
Mark Dickinson6b265f12009-03-18 16:07:26 +000042- Issue #4474: PyUnicode_FromWideChar now converts characters outside
43 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
44 and sizeof(Py_UNICODE) == 2.
45
Eric Smith6f42edb2009-03-14 11:57:26 +000046- Issue #5237: Allow auto-numbered fields in str.format(). For
47 example: '{} {}'.format(1, 2) == '1 2'.
48
Brett Cannon6c4cff02009-03-11 04:51:06 +000049- Issue #3652: Make the 'line' argument for warnings.showwarning() a
50 requirement. Means the DeprecationWarning from Python 2.6 can go away.
51
Eric Smithe9fb6862009-02-20 14:02:36 +000052- Issue #5247: Improve error message when unknown format codes are
53 used when using str.format() with str, unicode, long, int, and
54 float arguments.
55
Raymond Hettinger08259e82009-02-18 23:10:19 +000056- Running Python with the -3 option now also warns about classic division
57 for ints and longs.
58
Mark Dickinson2ffb26f2009-02-15 10:13:41 +000059- Issue #5260: Long integers now consume less memory: average
60 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
61 on a 64-bit system.
62
Antoine Pitrou76a4b892009-02-13 13:52:33 +000063- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
64 rotating the object pointer by 4 bits to the right.
65
Mark Dickinsonc97c9092009-02-09 14:18:43 +000066- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
67 it now forces its argument to double before testing for infinity.
68
Benjamin Petersone18ef192009-01-20 14:21:16 +000069- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
70
Raymond Hettingerb5163702009-02-02 21:50:13 +000071- Issue 1242657: the __len__() and __length_hint__() calls in several tools
72 were suppressing all exceptions. These include list(), filter(), map(),
73 zip(), and bytearray().
74
Benjamin Peterson596d3062009-01-19 15:42:23 +000075- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
76 functions.
77
Benjamin Peterson5848d1f2009-01-19 00:08:08 +000078- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
79 OSError.
80
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +000081- Issue #4807: Port the _winreg module to Windows CE.
82
Antoine Pitrouc2f02212009-01-13 23:13:52 +000083- Issue #4935: The overflow checking code in the expandtabs() method common
84 to str, bytes and bytearray could be optimized away by the compiler, letting
85 the interpreter segfault instead of raising an error.
86
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +000087- Issue #3720: Fix a crash when an iterator modifies its class and removes its
88 __next__ method.
89
Martin v. Löwise3422fa2009-01-12 08:11:24 +000090- Issue #4893: Use NT threading on CE.
91
Martin v. Löwis1b3bef22009-01-12 07:57:11 +000092- Issue #4915: Port sysmodule to Windows CE.
93
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +000094- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
95 collecting the oldest generation) so that allocating lots of objects without
96 destroying them does not show quadratic performance. Based on a proposal by
97 Martin von Löwis at
98 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
99
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000100- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
101
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000102- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
103 an existing .py counterpart, override the co_filename attributes of all
104 code objects if the original filename is obsolete (which can happen if the
105 file has been renamed, moved, or if it is accessed through different paths).
106 Patch by Ziga Seilnacht and Jean-Paul Calderone.
107
Martin v. Löwis5344c992009-01-02 20:32:55 +0000108- Issue #4075: Use OutputDebugStringW in Py_FatalError.
109
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000110- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
111 file with `str' filename on Windows.
112
Antoine Pitrouaa687902009-01-01 14:11:22 +0000113- Issue #3680: Reference cycles created through a dict, set or deque iterator
114 did not get collected.
115
Nick Coghlan180e4002008-12-30 01:18:48 +0000116- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
117 where the tp_hash and tp_dict slots are both NULL.
118
Benjamin Peterson7af65562008-12-29 17:56:58 +0000119- Issue #4764: With io.open, IOError.filename is set when trying to open a
120 directory on POSIX systems.
121
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000122- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
123 systems.
124
Georg Brandl6425a2f2008-12-28 11:54:53 +0000125- Issue #4759: None is now allowed as the first argument of
126 bytearray.translate(). It was always allowed for bytes.translate().
127
Skip Montanarof205c132008-12-23 03:30:15 +0000128- Added test case to ensure attempts to read from a file opened for writing
129 fail.
130
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000131- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
132 print elapsed times, not only when some objects are uncollectable /
133 unreachable. Original patch by Neil Schemenauer.
134
Mark Dickinson1a707982008-12-17 16:14:37 +0000135- Issue #3439: Add a bit_length method to int and long.
136

141 context manager returns a value that cannot be converted to a bool.
142
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000143- Issue #4597: Fixed several opcodes that weren't always propagating
144 exceptions.
145
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000146- Issue #4445: Replace "sizeof(PyStringObject)" with
147 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
148 str instances. On a typical machine this saves 3 bytes of memory
149 (on average) per string allocation.
150
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000151- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
152 interpreter to abort ("Fatal Python error: Could not reset the stack!")
153 instead of throwing a MemoryError.
154
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000155- Issue #3689: The list reversed iterator now supports __length_hint__

159 module couldn't be imported and \N escapes were present.
160
Vinay Sajip213faca2008-12-03 23:22:58 +0000161- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000162 method on file objects with closefd=False. The file descriptor is still
163 kept open but the file object behaves like a closed file. The ``FileIO``
164 object also got a new readonly attribute ``closefd``.
165
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000166- Issue #4348: Some bytearray methods returned that didn't cause any change to
167 the bytearray, returned the same bytearray instead of a copy.
168
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000169- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
170
Benjamin Peterson273c2332008-11-17 22:39:09 +0000171- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
172
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000173- Issue #4048: The parser module now correctly validates relative imports.
174
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000175- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
176 exec statement.
177
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000178- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
179 method does not return iterators for the 4th and 5th items.
180
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000181- Issue #4209: Enabling unicode_literals and the print_function in the same
182 __future__ import didn't work.
183
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000184- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000185 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000186
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000187- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
188 returned a path longer than MAX_PATH. (But It's doubtful this code path is
189 really executed because I cannot move to such directory on win2k)
190
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000191- Issue #4069: When set.remove(element) is used with a set element, the element
192 is temporarily replaced with an equivalent frozenset. But the eventual
193 KeyError would always report the empty frozenset([]) as the missing key. Now
194 it correctly refers to the initial element.
195
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000196- Issue #4509: Various issues surrounding resize of bytearray objects to
197 which there are buffer exports.
198
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000199- Issue #4748: Lambda generators no longer return a value.
200
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +0000201- Issue #3582: Use native TLS functions on Windows
202

216 to note the limitation
217
Michael Foord345b2fe2009-04-02 03:20:38 +0000218- unittest.assertNotEqual() now uses the inequality operator (!=) instead
219 of the equality operator.
220
221- Issue #5663: better failure messages for unittest asserts. Default assertTrue
222 and assertFalse messages are now useful. TestCase has a longMessage attribute.
223 This defaults to False, but if set to True useful error messages are shown in
224 addition to explicit messages passed to assert methods.
225
Jesse Nollerb502bc72009-04-02 02:32:55 +0000226- Issue #3110: Add additional protect around SEM_VALUE_MAX for multiprocessing

235 threads.
236
Raymond Hettinger66c4a6b2009-04-01 18:50:56 +0000237- Issue #5647: MutableSet.__iand__() no longer mutates self during iteration.

263 to wait 120 seconds for the socket to expire.
264
Guilherme Polo1972d162009-03-27 21:43:08 +0000265- Adjusted _tkinter to compile without warnings when WITH_THREAD is not
266 defined (part of issue #5035).
267
Marc-André Lemburgcbdf15b2009-03-25 19:45:33 +0000268- Issue #5561: Removed the sys.version_info shortcuts from platform's
269 python_version() and python_version_tuple() since they produced different
270 output compared to previous Python versions.
271
Benjamin Peterson692428e2009-03-23 21:50:21 +0000272- Issue #1034053: unittest now supports skipping tests and expected failures.
273
Gregory P. Smith28399852009-03-31 16:54:10 +0000274- The unittest.TestCase.assertRaises() method now returns a context manager when
275 not given a callable so that code to be tested can be written inline using
276 a with statement.
277
278- The unittest.TestCase.assertEqual() now displays the differences in lists,
279 tuples, dicts and sets on failure. Many new handy type and comparison
280 specific assert* methods have been added that fail with error messages
281 actually useful for debugging. Contributed in part by Google. [Issue #2578]

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000864- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
865 PyString_FromFormat or PyErr_Format to display size_t values. The macro
866 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
867 ``printf`` function, whereas PyString_FromFormat has an independent
868 implementation and uses "%zd" on all platforms for size_t values.
869 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000887 was correctly parsed but parsing of subsequent arguments failed.
888
Vinay Sajip35e3b032008-09-01 14:33:59 +0000889- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000890 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
891 mechanism. In the process, fix a bug where isinstance() and issubclass(),

965 warnings.catch_warnings() along with some API cleanup. Expanding the tests
966 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001033What's New in Python 2.6 beta 3?
1034================================
1035
Barry Warsaw07a4a382008-08-21 01:15:08 +00001036*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001037
1038Core and Builtins
1039-----------------
1040
Guido van Rossumf8402962008-08-20 15:01:50 +00001041- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1042 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1043 extensions do not automatically benefit from the class attribute
1044 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1045 to their tp_flags field if they care. This is a backwards
1046 compatibility feature; in 3.0, all types will use the cache by
1047 default.
1048
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001049- Keyword arguments can now follow starred arguments. (``f(a, *args,
1050 keyword=23)`` is now valid syntax.)
1051
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001052- ctypes function pointers that are COM methods have a boolean True
1053 value again.
1054
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001055- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1056 by denying s# to parse objects that have a releasebuffer procedure,
1057 and introducing s*.
1058
Georg Brandl1e13ea92008-08-11 09:07:59 +00001059- Issue #3537: Fix an assertion failure when an empty but presized dict
1060 object was stored in the freelist.
1061
Mark Dickinsonb6467572008-08-04 21:30:09 +00001062- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1063 ValueError consistently across platforms.
1064
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001065- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1066 (64bit Unix, for example), unichr() would truncate its argument and return
1067 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1068
Neal Norwitze7d8be82008-07-31 17:17:14 +00001069- Apply security patches from Apple.
1070
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001071- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1072 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1073
Antoine Pitrou92f82162008-07-25 22:22:08 +00001074- Issue #1819: function calls with several named parameters are now on
1075 average 35% faster (as measured by pybench).
1076
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001077- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1078 the python debugger steps into a class statement: the free variables (local
1079 variables defined in an outer scope) would be deleted from the outer scope.
1080
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001081- Issue #2620: Overflow checking when allocating or reallocating memory
1082 was not always being done properly in some python types and extension
1083 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1084 all been updated to perform better checks and places in the code that
1085 would previously leak memory on the error path when such an allocation
1086 failed have been fixed.

1090
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001091- Issue #3612: Added some missing basic types in ctypes.wintypes.
1092
Benjamin Petersone977ad42008-08-20 01:42:01 +00001093- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1094 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1095
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001096- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1097 version reported by these tools does not necessarily follow the python
1098 version numbering scheme, so the module is less strict when parsing it.
1099
Nick Coghlanf70385a2008-08-18 12:42:46 +00001100- Issue #2235: Added Py3k warnings for types which will become unhashable
1101 under the stricter __hash__ inheritance rules in 3.0. Several types
1102 which did not meet the rules for hash invariants and were already
1103 unhashable in 3.0 have now been explicitly flagged as unhashable in
1104 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1105 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1106
Brett Cannon88f801d2008-08-18 00:46:22 +00001107- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1108 imported into the module but exposed as part of the module's API.
1109
Brett Cannon7b96f072008-08-18 00:41:11 +00001110- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1111
Brett Cannon46225e72008-08-18 00:36:52 +00001112- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001114- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1115
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001116- Issue #3575: Incremental decoder's decode function now takes bytearray
1117 by using 's*' instead of 't#'.
1118
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001119- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001120 fails unicode conversion on 2nd parameter. (windows only)
1121
Facundo Batista94f243a2008-08-17 03:38:39 +00001122- Issue 2464. urllib2 now supports a malformation in the URL received
1123 in a redirect.
1124
Brett Cannonabe423e2008-08-16 21:47:07 +00001125- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001126 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001127
Facundo Batistaeb90b782008-08-16 14:44:07 +00001128- Issue #2776: fixed small issue when handling an URL with double slash
1129 after a 302 response in the case of not going through a proxy.
1130
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001131- Issue #2676: in the email package, content-type parsing was hanging on
1132 pathological input because of quadratic or exponential behaviour of a
1133 regular expression.
1134
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001135- Issue #3476: binary buffered reading through the new "io" library is now
1136 thread-safe.
1137
Brett Cannonbf3157b2008-08-14 05:00:03 +00001138- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1139 since mimetools itself is deprecated. Because modules are cached, all
1140 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1141
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001142- Issue #3134: shutil referenced undefined WindowsError symbol.
1143
Robert Schuppenies14646332008-08-10 11:01:53 +00001144- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1145 menu entries were not deleted.
1146
Brett Cannon83e81842008-08-09 23:30:55 +00001147- Copied the implementation of reduce() to _functools.reduce() to have a
1148 version that did not raise a DeprecationWarning under -3.
1149
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001150- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1151 a MemoryError rather than silently stop the iteration.
1152
Guido van Rossum59ce9012008-08-09 14:55:34 +00001153- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1154 to _sre.compile() will now be rejected. This should not affect anybody
1155 since the re.compile() function never generates invalid re-bytecode.
1156
Skip Montanaroa032bf42008-08-08 22:52:51 +00001157- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1158 upon first access it can be automatically initialized from the csv file if
1159 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00001161- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1162 the reload() built-in has been removed.
1163
Brett Cannon7e30b672008-08-04 21:52:25 +00001164- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001165 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001176 asking for a specific length. This problem only affected files opened
1177 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001178

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001227What's New in Python 2.6 beta 2?
1228================================
1229
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001230*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001232Core and Builtins
1233-----------------
1234
Georg Brandl3e483f62008-07-16 22:57:41 +00001235- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1236 its methods now allow for items objects that can be converted to
1237 an integer using operator.index().
1238
Mark Dickinson64b7e502008-07-16 09:40:03 +00001239- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1240 produced a ValueError instead of giving the correct float.
1241
Eric Smitha5fa5a22008-07-16 00:11:49 +00001242- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1243 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1244
Mark Dickinson7103aa42008-07-15 19:08:33 +00001245- Issue #3008: the float type has a new instance method 'float.hex'
1246 and a new class method 'float.fromhex' to convert floating-point
1247 numbers to and from hexadecimal strings, respectively.
1248
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001249- Issue #2235: __hash__ is once again inherited by default. To allow
1250 collections.Hashable to remain meaningful in the presence of the
1251 default hash implementation (object.__hash__), it is now possible
1252 to explicit block inheritance of hash by setting __hash__=None at
1253 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1254 level.
1255
Nick Coghlanb028f502008-07-13 14:52:36 +00001256- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1257 the parent module cannot be found while performing an absolute import.
1258 This means that an incorrectly defined __package__ attribute will
1259 now only prevent relative imports in that module rather than causing
1260 all imports from that module to fail.
1261
Nick Coghlan14ff9942008-07-08 14:21:42 +00001262- Issue #2517: Allow unicode messages in Exceptions again by correctly
1263 bypassing the instance dictionary when looking up __unicode__ on
1264 new-style classes.

1267 set to a custom object whose write() method happens to install
1268 another file in sys.stdout.
1269
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001270- Issue #3088: Corrected a race condition in classes derived from
1271 threading.local: the first member set by a thread could be saved in
1272 another thread's dictionary.
1273
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001274- Issue #3004: Minor change to slice.indices(): the start and stop
1275 arguments are now treated identically, making the behaviour easier
1276 to describe and understand. For example, slice(None, -10,
1277 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1278 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1279 10, -1).
1280
Georg Brandl278fc502008-07-19 12:46:12 +00001281- Issue #3219: Calling a function with repeated keyword arguments,
1282 f(a=2, a=23), would not cause a syntax error. This was a regression
1283 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001284
Georg Brandl278fc502008-07-19 12:46:12 +00001285- Issue #2862: Make int and float freelist management consistent with
1286 other freelists. Changes their CompactFreeList apis into
1287 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001292- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1293 api functions without holding the GIL, which could lead to a fatal
1294 error when they failed.
1295
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001296- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001321- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1322 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001323 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001324 content-length. The problem had been corrected in the 2.4 branch, but never
1325 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001340- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1341 handling is now the same as that of other special attributes like __name__).
1342
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001343- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00001795- Issue #1631171: Re-implement the 'warnings' module in C (the
1796 original Python code has been kept as backup). This will allow for
1797 using the 'warning's machinery in such places as the parser where
1798 use of pure Python code is not possible. Both the ``showarning()``
1799 and ``formatwarning()`` gain an optional 'line' argument which is
1800 not called by default for backwards-compatibility reasons. Setting
1801 ``warnings.showwarning()`` to an implementation that lacks support
1802 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001865- Issue #2550: The approach used by client/server code for obtaining
1866 ports to listen on in network-oriented tests has been refined in an
1867 effort to facilitate running multiple instances of the entire
1868 regression test suite in parallel without issue.
1869 test_support.bind_port() has been fixed such that it will always
1870 return a unique port -- which wasn't always the case with the
1871 previous implementation, especially if socket options had been set
1872 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1873 new implementation of bind_port() will actually raise an exception
1874 if it is passed an AF_INET/SOCK_STREAM socket with either the
1875 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1876 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1877 the socket it's been passed. This currently only applies to
1878 Windows. This option prevents any other sockets from binding to the
1879 host/port we've bound to, thus removing the possibility of the
1880 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1881 when a second SOCK_STREAM socket binds and accepts to a host/port
1882 that's already been bound by another socket. The optional preferred
1883 port parameter to bind_port() has been removed. Under no
1884 circumstances should tests be hard coding ports!
1885
1886 test_support.find_unused_port() has also been introduced, which will
1887 pass a temporary socket object to bind_port() in order to obtain an
1888 unused port. The temporary socket object is then closed and
1889 deleted, and the port is returned. This method should only be used
1890 for obtaining an unused port in order to pass to an external program
1891 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1892 a parameter to a server-oriented class that doesn't give you direct
1893 access to the underlying socket used.
1894
1895 Finally, test_support.HOST has been introduced, which should be used
1896 for the host argument of any relevant socket calls (i.e. bind and
1897 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001898
1899 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001900 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001901 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1902 test_asynchat and test_socket_ssl.
1903
Georg Brandl3ee81df2008-05-17 18:14:43 +00001904 It is now possible for multiple instances of the regression test
1905 suite to run in parallel without issue.

2172-----------------
2173
Fred Drakea8ee94b2008-03-01 02:45:07 +00002174- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002175 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002180
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002181- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002182 issue 215555 for a discussion.
2183
Eric Smitha73fbe72008-02-23 03:09:44 +00002184- Added the future_builtins module, which contains hex() and oct().
2185 These are the PEP 3127 version of these functions, designed to be
2186 compatible with the hex() and oct() builtins from Python 3.0. They
2187 differ slightly in their output formats from the existing, unchanged
2188 Python 2.6 builtins. The expected usage of the future_builtins
2189 module is:
2190 from future_builtins import hex, oct
2191
Eric Smith7ef40bf2008-02-20 23:34:22 +00002192- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2193 exponents for exponents with absolute value < 100. Follows C99
2194 standard. This is a change on Windows, which would use 3 digits.
2195 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2196 so that any alterations it does to the resulting string will be
2197 available in stringlib/formatter.h (for float.__format__).
2198
Eric Smith5a3c1352008-02-19 13:21:56 +00002199- Implemented PEP 3101, Advanced String Formatting. This adds a new
2200 builtin format(); a format() method for str and unicode; a
2201 __format__() method to object, str, unicode, int, long, float, and
2202 datetime; the class string.Formatter; and the C API
2203 PyObject_Format().
2204
Georg Brandl3ee81df2008-05-17 18:14:43 +00002205- Fixed several potential crashes, all caused by specially crafted
2206 __del__ methods exploiting objects in temporarily inconsistent
2207 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002208
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002209- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002210 prevent a possible crash: an Abstract Base Class would try to access
2211 a slot on a registered virtual subclass.

2218 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002219
Georg Brandl3ee81df2008-05-17 18:14:43 +00002220- Issue #2045: Fix an infinite recursion triggered when printing a
2221 subclass of collections.defaultdict, if its default_factory is set
2222 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002223
Christian Heimesf75dbef2008-02-08 00:11:31 +00002224- Fixed a minor memory leak in dictobject.c. The content of the free
2225 list was not freed on interpreter shutdown.
2226
Georg Brandl3ee81df2008-05-17 18:14:43 +00002227- Limit free list of method and builtin function objects to 256

2231 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002232 to compact the internal free lists of pre-allocted ints and floats.
2233
Georg Brandl3ee81df2008-05-17 18:14:43 +00002234- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2235 calls. Python expected the return type int but the fork familie
2236 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002250- Patch #1473257: generator objects gain a gi_code attribute. This is
2251 the same object as the func_code attribute of the function that
2252 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002253
Georg Brandl3ee81df2008-05-17 18:14:43 +00002254- Issue #1920: "while 0" statements were completely removed by the
2255 compiler, even in the presence of an "else" clause, which is
2256 supposed to be run when the condition is false. Now the compiler
2257 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002258

Georg Brandl6caad7d2008-01-26 14:19:22 +00002276- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002277 added.
2278
Christian Heimesc94e2b52008-01-14 04:13:37 +00002279- sys.float_info / PyFloat_GetInfo: The floating point information
2280 object was converted from a dict to a specialized structseq object.
2281
Georg Brandl3ee81df2008-05-17 18:14:43 +00002282- Patch #1816: Added sys.flags structseq. It exposes the status of
2283 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002284
Georg Brandl3ee81df2008-05-17 18:14:43 +00002285- Objects/structseq.c: Implemented new structseq representation. The
2286 patch makes structseqs (e.g. the return value of os.stat) more
2287 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002288
Georg Brandl3ee81df2008-05-17 18:14:43 +00002289- Patch #1700288: added a type attribute cache that caches method
2290 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002291
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002292- Bug #1776: __import__() no longer accepts filenames on any platform.
2293 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002294
Georg Brandlaed6c662008-01-07 17:25:53 +00002295- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2296
Georg Brandl3ee81df2008-05-17 18:14:43 +00002297- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2298 envvar and sys.dont_write_bytecode attribute. All these can be set
2299 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002300
Georg Brandl3ee81df2008-05-17 18:14:43 +00002301- Improve some exception messages when Windows fails to load an
2302 extension module. Now we get for example '%1 is not a valid Win32
2303 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002304
Georg Brandl3ee81df2008-05-17 18:14:43 +00002305- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002307- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2308 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002309
Christian Heimes0a8143f2007-12-18 23:22:54 +00002310- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002311 and INF. float("nan"), float("inf") and float("-inf") now work on
2312 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002313
Georg Brandl3ee81df2008-05-17 18:14:43 +00002314- Compiler now generates simpler and faster code for dictionary
2315 literals. The oparg for BUILD_MAP now indicates an estimated
2316 dictionary size. There is a new opcode, STORE_MAP, for adding
2317 entries to the dictionary.

2335 running, and if the deallocation of its frames somehow calls the
2336 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002337

Georg Brandl3ee81df2008-05-17 18:14:43 +00002346- Patch #1739468: Directories and zipfiles containing a __main__.py
2347 file can now be directly executed by passing their name to the
2348 interpreter. The directory/zipfile is automatically inserted as the
2349 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002350
Georg Brandl3ee81df2008-05-17 18:14:43 +00002351- Issue #1265: Fix a problem with sys.settrace, if the tracing
2352 function uses a generator expression when at the same time the
2353 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002354
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002355- sets and frozensets now have an isdisjoint() method.
2356

2358
Neal Norwitz44f326e2007-10-05 05:29:17 +00002359- Fix warnings found by the new version of the Coverity checker.
2360
Georg Brandl3ee81df2008-05-17 18:14:43 +00002361- The enumerate() builtin function is no longer bounded to sequences
2362 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2363 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002364
Georg Brandl3ee81df2008-05-17 18:14:43 +00002365- Issue #1686386: Tuple's tp_repr did not take into account the
2366 possibility of having a self-referential tuple, which is possible
2367 from C code. Nor did object's tp_str consider that a type's tp_str
2368 could do something that could lead to an inifinite recursion.
2369 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2370 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002371
Georg Brandl3ee81df2008-05-17 18:14:43 +00002372- Issue #1164: It was possible to trigger deadlock when using the
2373 'print' statement to write to a file since the GIL was not released
2374 as needed. Now PyObject_Print() does the right thing along with
2375 various tp_print implementations of the built-in types and those in
2376 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002377
Georg Brandl3ee81df2008-05-17 18:14:43 +00002378- Issue #1147: Exceptions were directly allowing string exceptions in
2379 their throw() method even though string exceptions no longer
2380 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002381
Georg Brandl3ee81df2008-05-17 18:14:43 +00002382- Issue #1096: Prevent a segfault from getting the repr of a very
2383 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002384
Brett Cannon1e534b52007-09-07 04:18:30 +00002385- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002386 PyObject_Call() never calling back out to Python code to trigger
2387 recursion depth updates/checks. Required the creation of a static
2388 RuntimeError instance in case normalizing an exception put the
2389 recursion check value past its limit. Fixes crashers
2390 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002391
Georg Brandl3ee81df2008-05-17 18:14:43 +00002392- Patch #1031213: Decode source line in SyntaxErrors back to its

2396 with %G.
2397
Georg Brandl3ee81df2008-05-17 18:14:43 +00002398- Prevent expandtabs() on string and unicode objects from causing a
2399 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002405- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002406 __*__ attributes. (Some already existed, e.g., __doc__ and
2407 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002408
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002409- Add -3 option to the interpreter to warn about features that are
2410 deprecated and will be changed/removed in Python 3.0.
2411
Georg Brandl2134e752007-05-21 20:34:16 +00002412- Patch #1686487: you can now pass any mapping after '**' in function
2413 calls.
2414
Collin Winter62903052007-05-18 23:11:24 +00002415- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002416 "except E as target:". This is to provide forwards compatibility
2417 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002418
Brett Cannon229cee22007-05-05 01:34:02 +00002419- Deprecate BaseException.message as per PEP 352.
2420
Georg Brandl3ee81df2008-05-17 18:14:43 +00002421- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002422 inherited from a builtin base.
2423
Vinay Sajip8549ce32007-05-06 17:53:37 +00002424- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002425 setting a plain string, ie don't expand to single letter identifiers.
2426
Raymond Hettinger13936692007-04-11 18:40:58 +00002427- Request #1191699: Slices can now be pickled.
2428
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002429- Request #1193128: str.translate() now allows a None argument for
2430 translations that only remove characters without re-mapping the
2431 remaining characters.
2432
Georg Brandl5cb76c12007-03-21 09:00:39 +00002433- Patch #1682205: a TypeError while unpacking an iterable is no longer
2434 masked by a generic one with the message "unpack non-sequence".
2435
Neal Norwitzaa754b72007-03-21 06:39:48 +00002436- Remove unused file Python/fmod.c.
2437
Guido van Rossum143b5642007-03-23 04:58:42 +00002438- Bug #1683368: The object.__init__() and object.__new__() methods are
2439 now stricter in rejecting excess arguments. The only time when
2440 either allows excess arguments is when it is not overridden and the
2441 other one is. For backwards compatibility, when both are
2442 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002443 warning later). Also, type.__init__() insists on the same signature
2444 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002445
Georg Brandl3ee81df2008-05-17 18:14:43 +00002446- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2447 object to complex using its __complex__() method before falling back
2448 to the __float__() method. Therefore, the functions in the cmath
2449 module now can operate on objects that define a __complex__()
2450 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002451
Georg Brandl3ee81df2008-05-17 18:14:43 +00002452- Patch #1623563: allow __class__ assignment for classes with
2453 __slots__. The old and the new class are still required to have the
2454 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002455

Georg Brandl3ee81df2008-05-17 18:14:43 +00002459- Patch #1462488: Python no longer segfaults when
2460 ``object.__reduce_ex__()`` is called with an object that is faking
2461 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002462
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002466- Patch #1444529: the builtin compile() now accepts keyword arguments.
2467
Georg Brandl7b9c5552007-03-12 14:30:05 +00002468- Bug #1678647: write a newline after printing an exception in any
2469 case, even when converting the value to a string failed.
2470
Georg Brandl871f1bc2007-03-12 13:17:36 +00002471- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002472 its argument, if it exists. If not, it will work like before. This
2473 allows customizing the output of dir() in the presence of a
2474 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002475
Collin Winter276887b2007-03-12 16:11:39 +00002476- Patch #922167: Python no longer segfaults when faced with infinitely
2477 self-recursive reload() calls (as reported by bug #742342).
2478
Georg Brandl3ee81df2008-05-17 18:14:43 +00002479- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002482- Patch #1491866: change the complex() constructor to allow
2483 parthensized forms. This means complex(repr(x)) now works instead of
2484 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002485
Georg Brandlaa2321b2007-03-07 00:40:28 +00002486- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002487 makes the filenames the warning module prints much more sensible
2488 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002489
Georg Brandl49aafc92007-03-07 00:34:46 +00002490- Variant of patch #697613: don't exit the interpreter on a SystemExit
2491 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002492 variable is given, but break into the interactive interpreter just
2493 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002501- Patch #1674228: when assigning a slice (old-style), check for the
2502 sq_ass_slice instead of the sq_slice slot.
2503
Georg Brandl3ee81df2008-05-17 18:14:43 +00002504- When printing an unraisable error, don't print exceptions. before
2505 the name. This duplicates the behavior whening normally printing
2506 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002507
Georg Brandl3ee81df2008-05-17 18:14:43 +00002508- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003008- Added a timeout parameter to the constructor of other protocols
3009 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3010 work started with create_connection() and timeout in httplib, and
3011 closes patch #723312.
3012
Vinay Sajip8549ce32007-05-06 17:53:37 +00003013- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista70f996b2007-05-21 17:32:32 +00003015 and HTTPSConnection now accept an optional timeout).

3037
Georg Brandlf66b6032007-03-14 08:27:52 +00003038- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003039 AttributeError instead of an IOError when the server's response
3040 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003041

Georg Brandl3ee81df2008-05-17 18:14:43 +00003046- Patch #1429539: pdb now correctly initializes the __main__ module
3047 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003048 correctly now.
3049

3056
Georg Brandl3ee81df2008-05-17 18:14:43 +00003057- Patch #1530482: add pydoc.render_doc() which returns the

3068 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00003070- Patch #1581073: add a flag to textwrap that prevents the dropping of
3071 whitespace while wrapping.
3072
Georg Brandl92a6bae2007-03-13 17:43:32 +00003073- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003074 are set for invalid interpolation sequences that would lead to
3075 errors on reading back those values.

3118 returned string up to the first NUL character.
3119

3129
Georg Brandl3ee81df2008-05-17 18:14:43 +00003130- unittest now verifies more of its assumptions. In particular,
3131 TestCase and TestSuite subclasses (not instances) are no longer
3132 accepted in TestSuite.addTest(). This should cause no
3133 incompatibility since it never made sense with ordinary subclasses
3134 -- the failure just occurred later, with a more cumbersome
3135 exception.

3145
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146- Patch #1673619: setup.py identifies extension modules it doesn't

3506 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Georg Brandl3ee81df2008-05-17 18:14:43 +00003524 time so that opening a database previously created with the DB_DUP
3525 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3526 opens. Specifically: dictionary assignment to a DB object will
3527 replace all values for a given key when the database allows
3528 duplicate values. DB users should use DB.put(k, v) when they want
3529 to store duplicates; not DB[k] = v.

3536 characters with ASCII value less than 32. Also, it correctly quotes
3537 dots only if they occur on a single line, as opposed to the previous
3538 behavior of quoting dots if they are the second character of any
3539 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003540

3885 of w# format code incorrectly truncated the length to an int, even
3886 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3887 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003917- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3918 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
