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
R. David Murray0374a822009-04-09 21:54:50 +000015- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
16 its clarity and its speed.
17
Antoine Pitrou789be0c2009-04-02 21:18:34 +000018- Issue #2396: the memoryview object was backported from Python 3.1.
19
Georg Brandld3f03fa2009-04-02 18:09:04 +000020- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
21 when hitting the recursion limit under certain circumstances.
22
Brett Cannon15ba4da2009-04-01 18:03:59 +000023- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
24
Ronald Oussorene0154ed2009-03-30 23:10:35 +000025- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
26 the end sys.path, for compatibility with the system install of Python.
27
Antoine Pitrouf8387af2009-03-23 18:41:45 +000028- Issue #4688: Add a heuristic so that tuples and dicts containing only
29 untrackable objects are not tracked by the garbage collector. This can
30 reduce the size of collections and therefore the garbage collection overhead
31 on long-running programs, depending on their particular use of datatypes.
32
Mark Dickinson0b666bf2009-03-23 18:25:13 +000033- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
34 improve its performance. Long divisions and remainder operations
35 are now between 50% and 150% faster.
36
Mark Dickinsonefc82f72009-03-20 15:51:55 +000037- Issue #4258: Make it possible to use base 2**30 instead of base
38 2**15 for the internal representation of integers, for performance
39 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
40 --enable-big-digits option to configure, which overrides the
41 default. Add sys.long_info structseq to provide information about
42 the internal format.
43
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000044- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
45 result traceback.__members__ no longer exists.)
46
Mark Dickinson6b265f12009-03-18 16:07:26 +000047- Issue #4474: PyUnicode_FromWideChar now converts characters outside
48 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
49 and sizeof(Py_UNICODE) == 2.
50
Eric Smith6f42edb2009-03-14 11:57:26 +000051- Issue #5237: Allow auto-numbered fields in str.format(). For
52 example: '{} {}'.format(1, 2) == '1 2'.
53
Brett Cannon6c4cff02009-03-11 04:51:06 +000054- Issue #3652: Make the 'line' argument for warnings.showwarning() a
55 requirement. Means the DeprecationWarning from Python 2.6 can go away.
56
Eric Smithe9fb6862009-02-20 14:02:36 +000057- Issue #5247: Improve error message when unknown format codes are
58 used when using str.format() with str, unicode, long, int, and
59 float arguments.
60
Raymond Hettinger08259e82009-02-18 23:10:19 +000061- Running Python with the -3 option now also warns about classic division
62 for ints and longs.
63
Mark Dickinson2ffb26f2009-02-15 10:13:41 +000064- Issue #5260: Long integers now consume less memory: average
65 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
66 on a 64-bit system.
67
Antoine Pitrou76a4b892009-02-13 13:52:33 +000068- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
69 rotating the object pointer by 4 bits to the right.
70
Mark Dickinsonc97c9092009-02-09 14:18:43 +000071- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
72 it now forces its argument to double before testing for infinity.
73
Benjamin Petersone18ef192009-01-20 14:21:16 +000074- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
75
Georg Brandl29c6a282009-04-05 20:23:13 +000076- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +000077 were suppressing all exceptions. These include list(), filter(), map(),
78 zip(), and bytearray().
79
Benjamin Peterson596d3062009-01-19 15:42:23 +000080- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
81 functions.
82
Benjamin Peterson5848d1f2009-01-19 00:08:08 +000083- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
84 OSError.
85
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +000086- Issue #4807: Port the _winreg module to Windows CE.
87
Antoine Pitrouc2f02212009-01-13 23:13:52 +000088- Issue #4935: The overflow checking code in the expandtabs() method common
89 to str, bytes and bytearray could be optimized away by the compiler, letting
90 the interpreter segfault instead of raising an error.
91
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +000092- Issue #3720: Fix a crash when an iterator modifies its class and removes its
93 __next__ method.
94
Martin v. Löwise3422fa2009-01-12 08:11:24 +000095- Issue #4893: Use NT threading on CE.
96
Martin v. Löwis1b3bef22009-01-12 07:57:11 +000097- Issue #4915: Port sysmodule to Windows CE.
98
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +000099- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
100 collecting the oldest generation) so that allocating lots of objects without
101 destroying them does not show quadratic performance. Based on a proposal by
102 Martin von Löwis at
103 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
104
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000105- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
106
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000107- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
108 an existing .py counterpart, override the co_filename attributes of all
109 code objects if the original filename is obsolete (which can happen if the
110 file has been renamed, moved, or if it is accessed through different paths).
111 Patch by Ziga Seilnacht and Jean-Paul Calderone.
112
Martin v. Löwis5344c992009-01-02 20:32:55 +0000113- Issue #4075: Use OutputDebugStringW in Py_FatalError.
114
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000115- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
116 file with `str' filename on Windows.
117
Antoine Pitrouaa687902009-01-01 14:11:22 +0000118- Issue #3680: Reference cycles created through a dict, set or deque iterator
119 did not get collected.
120
Nick Coghlan180e4002008-12-30 01:18:48 +0000121- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
122 where the tp_hash and tp_dict slots are both NULL.
123
Benjamin Peterson7af65562008-12-29 17:56:58 +0000124- Issue #4764: With io.open, IOError.filename is set when trying to open a
125 directory on POSIX systems.
126
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000127- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
128 systems.
129
Georg Brandl6425a2f2008-12-28 11:54:53 +0000130- Issue #4759: None is now allowed as the first argument of
131 bytearray.translate(). It was always allowed for bytes.translate().
132
Skip Montanarof205c132008-12-23 03:30:15 +0000133- Added test case to ensure attempts to read from a file opened for writing
134 fail.
135
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000136- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
137 print elapsed times, not only when some objects are uncollectable /
138 unreachable. Original patch by Neil Schemenauer.
139
Mark Dickinson1a707982008-12-17 16:14:37 +0000140- Issue #3439: Add a bit_length method to int and long.
141
Antoine Pitroud0c35152008-12-17 00:38:28 +0000142- Issue #2183: Simplify and optimize bytecode for list comprehensions.
143 Original patch by Neal Norwitz.
144

146 context manager returns a value that cannot be converted to a bool.
147
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000148- Issue #4597: Fixed several opcodes that weren't always propagating
149 exceptions.
150
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000151- Issue #4445: Replace "sizeof(PyStringObject)" with
152 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
153 str instances. On a typical machine this saves 3 bytes of memory
154 (on average) per string allocation.
155
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000156- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
157 interpreter to abort ("Fatal Python error: Could not reset the stack!")
158 instead of throwing a MemoryError.
159
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000160- Issue #3689: The list reversed iterator now supports __length_hint__
161 instead of __len__. Behavior now matches other reversed iterators.
162
Benjamin Petersonc078f922008-11-21 22:27:24 +0000163- Issue #4367: Python would segfault during compiling when the unicodedata
164 module couldn't be imported and \N escapes were present.
165
Vinay Sajip213faca2008-12-03 23:22:58 +0000166- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000167 method on file objects with closefd=False. The file descriptor is still
168 kept open but the file object behaves like a closed file. The ``FileIO``
169 object also got a new readonly attribute ``closefd``.
170
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000171- Issue #4348: Some bytearray methods returned that didn't cause any change to
172 the bytearray, returned the same bytearray instead of a copy.
173
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000174- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
175
Benjamin Peterson273c2332008-11-17 22:39:09 +0000176- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
177
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000178- Issue #4048: The parser module now correctly validates relative imports.
179
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000180- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
181 exec statement.
182
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000183- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
184 method does not return iterators for the 4th and 5th items.
185
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000186- Issue #4209: Enabling unicode_literals and the print_function in the same
187 __future__ import didn't work.
188
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000189- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000190 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000191
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000192- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
193 returned a path longer than MAX_PATH. (But It's doubtful this code path is
194 really executed because I cannot move to such directory on win2k)
195
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000196- Issue #4069: When set.remove(element) is used with a set element, the element
197 is temporarily replaced with an equivalent frozenset. But the eventual
198 KeyError would always report the empty frozenset([]) as the missing key. Now
199 it correctly refers to the initial element.
200
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000201- Issue #4509: Various issues surrounding resize of bytearray objects to
202 which there are buffer exports.
203

209
Matthias Kloseedb5e1e2009-04-04 14:18:13 +0000210- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
211 short file names.
212
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000213- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
214 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000215
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000216- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
217 returned them on 64bit platforms.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000901- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
902
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000903- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
904 PyString_FromFormat or PyErr_Format to display size_t values. The macro
905 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
906 ``printf`` function, whereas PyString_FromFormat has an independent
907 implementation and uses "%zd" on all platforms for size_t values.
908 This makes a difference on win64, where ``printf`` needs "%Id" to display
909 64bit values.
910
Benjamin Peterson97179b02008-09-09 20:55:01 +0000911- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
912 error.
913
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000914- Issue #3777: long() applied to a float object now always return a long
915 object; previously an int would be returned for small values. the __long__
916 method is allowed to return either an int or a long, but the behaviour of
917 float objects should not change to respect backward compatibility.
918
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000919- Issue #3751: str.rpartition would perform a left-partition when called with
920 a unicode argument.
921
Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000922- Issue #3683: Fix compilation when --without-threads is given.
923
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000924- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +0000925 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000926 was correctly parsed but parsing of subsequent arguments failed.
927
Vinay Sajip35e3b032008-09-01 14:33:59 +0000928- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000929 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
930 mechanism. In the process, fix a bug where isinstance() and issubclass(),
931 when given a tuple of classes as second argument, were looking up
932 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
933 type object.
934
Neal Norwitz18aa3882008-08-24 05:04:52 +0000935- Fix crashes on memory allocation failure found with failmalloc.
936
937- Fix memory leaks found with valgrind and update suppressions file.
938
939- Fix compiler warnings in opt mode which would lead to invalid memory reads.
940
941- Fix problem using wrong name in decimal module reported by pychecker.
942
Christian Heimes7d4c3172008-08-22 19:47:25 +0000943- Silenced another compiler warning about a used but not defined
944 function 'stringlib_contains_obj'.
945
Benjamin Peterson712ee922008-08-24 18:10:20 +0000946- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
947 ``__delslice__``.
948
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +0000949- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
950 library targets in the Makefile.
951
Gregory P. Smith980b99b2008-09-07 05:15:18 +0000952- Issue #1204: The configure script now tests for additional libraries
953 that may be required when linking against readline. This fixes issues
954 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +0000971- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
972 silent misbehaviour when a single instance is nested in multiple

976
Nick Coghland2e09382008-09-11 12:11:06 +0000977- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +0000978 return a list or None rather than a custom object.

1004 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1005 for catch_warnings() also led to an improvement in the raising of a
1006 DeprecationWarning related to warnings.warn_explicit().
1007
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001008- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001076
1077Core and Builtins
1078-----------------
1079
Guido van Rossumf8402962008-08-20 15:01:50 +00001080- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1081 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1082 extensions do not automatically benefit from the class attribute
1083 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1084 to their tp_flags field if they care. This is a backwards
1085 compatibility feature; in 3.0, all types will use the cache by
1086 default.
1087
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001088- Keyword arguments can now follow starred arguments. (``f(a, *args,
1089 keyword=23)`` is now valid syntax.)
1090
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001091- ctypes function pointers that are COM methods have a boolean True
1092 value again.
1093
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001094- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1095 by denying s# to parse objects that have a releasebuffer procedure,
1096 and introducing s*.
1097
Georg Brandl1e13ea92008-08-11 09:07:59 +00001098- Issue #3537: Fix an assertion failure when an empty but presized dict
1099 object was stored in the freelist.
1100
Mark Dickinsonb6467572008-08-04 21:30:09 +00001101- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1102 ValueError consistently across platforms.
1103
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001104- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1105 (64bit Unix, for example), unichr() would truncate its argument and return
1106 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1107
Neal Norwitze7d8be82008-07-31 17:17:14 +00001108- Apply security patches from Apple.
1109
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001110- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1111 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1112
Antoine Pitrou92f82162008-07-25 22:22:08 +00001113- Issue #1819: function calls with several named parameters are now on
1114 average 35% faster (as measured by pybench).
1115
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001116- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1117 the python debugger steps into a class statement: the free variables (local
1118 variables defined in an outer scope) would be deleted from the outer scope.
1119
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001120- Issue #2620: Overflow checking when allocating or reallocating memory
1121 was not always being done properly in some python types and extension
1122 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1123 all been updated to perform better checks and places in the code that
1124 would previously leak memory on the error path when such an allocation
1125 failed have been fixed.

1131
Benjamin Petersone977ad42008-08-20 01:42:01 +00001132- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1133 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1134
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001135- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1136 version reported by these tools does not necessarily follow the python
1137 version numbering scheme, so the module is less strict when parsing it.
1138
Nick Coghlanf70385a2008-08-18 12:42:46 +00001139- Issue #2235: Added Py3k warnings for types which will become unhashable
1140 under the stricter __hash__ inheritance rules in 3.0. Several types
1141 which did not meet the rules for hash invariants and were already
1142 unhashable in 3.0 have now been explicitly flagged as unhashable in
1143 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1144 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1145
Brett Cannon88f801d2008-08-18 00:46:22 +00001146- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1147 imported into the module but exposed as part of the module's API.
1148
Brett Cannon7b96f072008-08-18 00:41:11 +00001149- Remove an unneeded import of abc.ABCMeta from 'inspect'.

1154
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001155- Issue #3575: Incremental decoder's decode function now takes bytearray
1156 by using 's*' instead of 't#'.
1157
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001158- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001159 fails unicode conversion on 2nd parameter. (windows only)
1160
Facundo Batista94f243a2008-08-17 03:38:39 +00001161- Issue 2464. urllib2 now supports a malformation in the URL received
1162 in a redirect.
1163
Brett Cannonabe423e2008-08-16 21:47:07 +00001164- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001165 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001166
Facundo Batistaeb90b782008-08-16 14:44:07 +00001167- Issue #2776: fixed small issue when handling an URL with double slash
1168 after a 302 response in the case of not going through a proxy.
1169
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001170- Issue #2676: in the email package, content-type parsing was hanging on

Antoine Pitroude781a42008-08-09 12:43:23 +00001215 asking for a specific length. This problem only affected files opened

1259
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001260- Issue #643841: The language reference now provides more detailed

1272-----------------
1273
Georg Brandl3e483f62008-07-16 22:57:41 +00001274- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1275 its methods now allow for items objects that can be converted to
1276 an integer using operator.index().
1277
Mark Dickinson64b7e502008-07-16 09:40:03 +00001278- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1279 produced a ValueError instead of giving the correct float.
1280
Eric Smitha5fa5a22008-07-16 00:11:49 +00001281- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1282 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1283
Mark Dickinson7103aa42008-07-15 19:08:33 +00001284- Issue #3008: the float type has a new instance method 'float.hex'
1285 and a new class method 'float.fromhex' to convert floating-point
1286 numbers to and from hexadecimal strings, respectively.
1287
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001288- Issue #2235: __hash__ is once again inherited by default. To allow
1289 collections.Hashable to remain meaningful in the presence of the
1290 default hash implementation (object.__hash__), it is now possible
1291 to explicit block inheritance of hash by setting __hash__=None at
1292 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1293 level.
1294
Nick Coghlanb028f502008-07-13 14:52:36 +00001295- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1296 the parent module cannot be found while performing an absolute import.
1297 This means that an incorrectly defined __package__ attribute will
1298 now only prevent relative imports in that module rather than causing
1299 all imports from that module to fail.
1300
Nick Coghlan14ff9942008-07-08 14:21:42 +00001301- Issue #2517: Allow unicode messages in Exceptions again by correctly

1311 another thread's dictionary.
1312
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001313- Issue #3004: Minor change to slice.indices(): the start and stop
1314 arguments are now treated identically, making the behaviour easier
1315 to describe and understand. For example, slice(None, -10,
1316 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1317 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1318 10, -1).
1319
Georg Brandl278fc502008-07-19 12:46:12 +00001320- Issue #3219: Calling a function with repeated keyword arguments,
1321 f(a=2, a=23), would not cause a syntax error. This was a regression
1322 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001323
Georg Brandl278fc502008-07-19 12:46:12 +00001324- Issue #2862: Make int and float freelist management consistent with
1325 other freelists. Changes their CompactFreeList apis into

1333 error when they failed.
1334
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001335- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001360- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1361 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001362 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001363 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001379- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Benjamin Peterson23681932008-05-12 21:42:13 +00001749
Vinay Sajip9828b7e2008-06-17 11:04:02 +00001750- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001751 environment to control the '-arch' flags that are used to build
1752 an extension. This was added for compatibility with Apple's build
1753 of Python.
1754
1755- The bundled OSX-specific copy of libbffi is now in sync with the version
1756 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
1757
Georg Brandl25c34082008-08-18 23:09:49 +00001758- The threading module gained aliases for names that will be removed in the

1767
Brett Cannonb61d8012008-05-11 23:39:04 +00001768- ``Lib/lib-old`` is now added to sys.path.
1769
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001770- On MacOS X it is now possible to install the framework in 64-bit
1771 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001772 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001773
1774 This is controlled by the configure argument ``--with-universal-archs``:
1775
1776 - ``--with-universal-archs=all``: install 4-way universal
1777
1778 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1779
1780 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1781
1782 This option should be used in combination with ``--enable-universalsdk=``.
1783
1784 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00001834- Issue #1631171: Re-implement the 'warnings' module in C (the
1835 original Python code has been kept as backup). This will allow for
1836 using the 'warning's machinery in such places as the parser where
1837 use of pure Python code is not possible. Both the ``showarning()``
1838 and ``formatwarning()`` gain an optional 'line' argument which is
1839 not called by default for backwards-compatibility reasons. Setting
1840 ``warnings.showwarning()`` to an implementation that lacks support
1841 for the ``line`` argument will raise a DeprecationWarning.

1865
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001866- The getpass module has been improved on Unix. It now uses /dev/tty
1867 by default and uses stderr instead of stdout. A GetPassWarning is
1868 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00001869

Georg Brandl3ee81df2008-05-17 18:14:43 +00001883- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001884 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001904- Issue #2550: The approach used by client/server code for obtaining
1905 ports to listen on in network-oriented tests has been refined in an
1906 effort to facilitate running multiple instances of the entire
1907 regression test suite in parallel without issue.
1908 test_support.bind_port() has been fixed such that it will always
1909 return a unique port -- which wasn't always the case with the
1910 previous implementation, especially if socket options had been set
1911 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1912 new implementation of bind_port() will actually raise an exception
1913 if it is passed an AF_INET/SOCK_STREAM socket with either the
1914 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1915 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1916 the socket it's been passed. This currently only applies to
1917 Windows. This option prevents any other sockets from binding to the
1918 host/port we've bound to, thus removing the possibility of the
1919 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1920 when a second SOCK_STREAM socket binds and accepts to a host/port
1921 that's already been bound by another socket. The optional preferred
1922 port parameter to bind_port() has been removed. Under no
1923 circumstances should tests be hard coding ports!
1924
1925 test_support.find_unused_port() has also been introduced, which will
1926 pass a temporary socket object to bind_port() in order to obtain an
1927 unused port. The temporary socket object is then closed and
1928 deleted, and the port is returned. This method should only be used
1929 for obtaining an unused port in order to pass to an external program
1930 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1931 a parameter to a server-oriented class that doesn't give you direct
1932 access to the underlying socket used.
1933
1934 Finally, test_support.HOST has been introduced, which should be used
1935 for the host argument of any relevant socket calls (i.e. bind and
1936 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001937
1938 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001939 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001940 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1941 test_asynchat and test_socket_ssl.
1942
Georg Brandl3ee81df2008-05-17 18:14:43 +00001943 It is now possible for multiple instances of the regression test
1944 suite to run in parallel without issue.

2211-----------------
2212
Fred Drakea8ee94b2008-03-01 02:45:07 +00002213- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002214 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002219
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002220- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002221 issue 215555 for a discussion.
2222
Eric Smitha73fbe72008-02-23 03:09:44 +00002223- Added the future_builtins module, which contains hex() and oct().
2224 These are the PEP 3127 version of these functions, designed to be
2225 compatible with the hex() and oct() builtins from Python 3.0. They
2226 differ slightly in their output formats from the existing, unchanged
2227 Python 2.6 builtins. The expected usage of the future_builtins
2228 module is:
2229 from future_builtins import hex, oct
2230
Eric Smith7ef40bf2008-02-20 23:34:22 +00002231- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2232 exponents for exponents with absolute value < 100. Follows C99
2233 standard. This is a change on Windows, which would use 3 digits.
2234 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2235 so that any alterations it does to the resulting string will be
2236 available in stringlib/formatter.h (for float.__format__).
2237
Eric Smith5a3c1352008-02-19 13:21:56 +00002238- Implemented PEP 3101, Advanced String Formatting. This adds a new
2239 builtin format(); a format() method for str and unicode; a
2240 __format__() method to object, str, unicode, int, long, float, and
2241 datetime; the class string.Formatter; and the C API
2242 PyObject_Format().
2243
Georg Brandl3ee81df2008-05-17 18:14:43 +00002244- Fixed several potential crashes, all caused by specially crafted
2245 __del__ methods exploiting objects in temporarily inconsistent
2246 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002247
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002248- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002249 prevent a possible crash: an Abstract Base Class would try to access
2250 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002251

2253 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002255- Clear all free lists during a gc.collect() of the highest generation
2256 in order to allow pymalloc to free more arenas. Python may give back
2257 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002258
Georg Brandl3ee81df2008-05-17 18:14:43 +00002259- Issue #2045: Fix an infinite recursion triggered when printing a
2260 subclass of collections.defaultdict, if its default_factory is set
2261 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002262
Christian Heimesf75dbef2008-02-08 00:11:31 +00002263- Fixed a minor memory leak in dictobject.c. The content of the free
2264 list was not freed on interpreter shutdown.
2265
Georg Brandl3ee81df2008-05-17 18:14:43 +00002266- Limit free list of method and builtin function objects to 256
2267 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002268
Georg Brandl3ee81df2008-05-17 18:14:43 +00002269- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2270 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002271 to compact the internal free lists of pre-allocted ints and floats.
2272
Georg Brandl3ee81df2008-05-17 18:14:43 +00002273- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2274 calls. Python expected the return type int but the fork familie
2275 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002276
Georg Brandl3ee81df2008-05-17 18:14:43 +00002277- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2278 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002279
Georg Brandl3ee81df2008-05-17 18:14:43 +00002280- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2281 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002282
Georg Brandl3ee81df2008-05-17 18:14:43 +00002283- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2284 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002285
Georg Brandl3ee81df2008-05-17 18:14:43 +00002286- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2287 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002288
Georg Brandl3ee81df2008-05-17 18:14:43 +00002289- Patch #1473257: generator objects gain a gi_code attribute. This is
2290 the same object as the func_code attribute of the function that
2291 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002292
Georg Brandl3ee81df2008-05-17 18:14:43 +00002293- Issue #1920: "while 0" statements were completely removed by the
2294 compiler, even in the presence of an "else" clause, which is
2295 supposed to be run when the condition is false. Now the compiler
2296 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002297
Guido van Rossumeead05f2008-01-24 18:21:02 +00002298- A few crashers fixed: weakref_in_del.py (issue #1377858);
2299 loosing_dict_ref.py (issue #1303614, test67.py);
2300 borrowed_ref_[34].py (not in tracker).
2301
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002302- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002303 suppressed while an extension is loaded by calling SetErrorMode in
2304 dynload_win.c. The error is still reported properly.
2305
Georg Brandl3ee81df2008-05-17 18:14:43 +00002306- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002307 several extension methods and modules do not work without unicode
2308 support.
2309
Georg Brandl26543b12008-01-21 18:36:51 +00002310- Issue #1882: when compiling code from a string, encoding cookies in the
2311 second line of code were not always recognized correctly.
2312
Georg Brandl14404b62008-01-19 19:27:05 +00002313- Issue #1679: "0x" was taken as a valid integer literal.
2314
Georg Brandl6caad7d2008-01-26 14:19:22 +00002315- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002316 added.
2317
Christian Heimesc94e2b52008-01-14 04:13:37 +00002318- sys.float_info / PyFloat_GetInfo: The floating point information
2319 object was converted from a dict to a specialized structseq object.
2320
Georg Brandl3ee81df2008-05-17 18:14:43 +00002321- Patch #1816: Added sys.flags structseq. It exposes the status of
2322 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002323
Georg Brandl3ee81df2008-05-17 18:14:43 +00002324- Objects/structseq.c: Implemented new structseq representation. The
2325 patch makes structseqs (e.g. the return value of os.stat) more
2326 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002327
Georg Brandl3ee81df2008-05-17 18:14:43 +00002328- Patch #1700288: added a type attribute cache that caches method
2329 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002330
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002331- Bug #1776: __import__() no longer accepts filenames on any platform.
2332 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002333
Georg Brandlaed6c662008-01-07 17:25:53 +00002334- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2335
Georg Brandl3ee81df2008-05-17 18:14:43 +00002336- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2337 envvar and sys.dont_write_bytecode attribute. All these can be set
2338 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002339
Georg Brandl3ee81df2008-05-17 18:14:43 +00002340- Improve some exception messages when Windows fails to load an
2341 extension module. Now we get for example '%1 is not a valid Win32
2342 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002343

Georg Brandl3ee81df2008-05-17 18:14:43 +00002346- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2347 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002348
Christian Heimes0a8143f2007-12-18 23:22:54 +00002349- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002350 and INF. float("nan"), float("inf") and float("-inf") now work on
2351 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002352
Georg Brandl3ee81df2008-05-17 18:14:43 +00002353- Compiler now generates simpler and faster code for dictionary
2354 literals. The oparg for BUILD_MAP now indicates an estimated
2355 dictionary size. There is a new opcode, STORE_MAP, for adding
2356 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002385- Patch #1739468: Directories and zipfiles containing a __main__.py
2386 file can now be directly executed by passing their name to the
2387 interpreter. The directory/zipfile is automatically inserted as the
2388 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002389
Georg Brandl3ee81df2008-05-17 18:14:43 +00002390- Issue #1265: Fix a problem with sys.settrace, if the tracing
2391 function uses a generator expression when at the same time the
2392 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002393
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002394- sets and frozensets now have an isdisjoint() method.
2395

2397
Neal Norwitz44f326e2007-10-05 05:29:17 +00002398- Fix warnings found by the new version of the Coverity checker.
2399
Georg Brandl3ee81df2008-05-17 18:14:43 +00002400- The enumerate() builtin function is no longer bounded to sequences
2401 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2402 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002403
Georg Brandl3ee81df2008-05-17 18:14:43 +00002404- Issue #1686386: Tuple's tp_repr did not take into account the
2405 possibility of having a self-referential tuple, which is possible
2406 from C code. Nor did object's tp_str consider that a type's tp_str
2407 could do something that could lead to an inifinite recursion.
2408 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2409 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002410
Georg Brandl3ee81df2008-05-17 18:14:43 +00002411- Issue #1164: It was possible to trigger deadlock when using the
2412 'print' statement to write to a file since the GIL was not released
2413 as needed. Now PyObject_Print() does the right thing along with
2414 various tp_print implementations of the built-in types and those in
2415 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002416
Georg Brandl3ee81df2008-05-17 18:14:43 +00002417- Issue #1147: Exceptions were directly allowing string exceptions in
2418 their throw() method even though string exceptions no longer
2419 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002420
Georg Brandl3ee81df2008-05-17 18:14:43 +00002421- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002423
Brett Cannon1e534b52007-09-07 04:18:30 +00002424- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002425 PyObject_Call() never calling back out to Python code to trigger
2426 recursion depth updates/checks. Required the creation of a static
2427 RuntimeError instance in case normalizing an exception put the
2428 recursion check value past its limit. Fixes crashers
2429 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002430

Neal Norwitz0ac60192007-05-27 04:08:54 +00002444- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002445 __*__ attributes. (Some already existed, e.g., __doc__ and
2446 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002447
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002448- Add -3 option to the interpreter to warn about features that are
2449 deprecated and will be changed/removed in Python 3.0.
2450
Georg Brandl2134e752007-05-21 20:34:16 +00002451- Patch #1686487: you can now pass any mapping after '**' in function
2452 calls.
2453
Collin Winter62903052007-05-18 23:11:24 +00002454- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002455 "except E as target:". This is to provide forwards compatibility
2456 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002457
Brett Cannon229cee22007-05-05 01:34:02 +00002458- Deprecate BaseException.message as per PEP 352.
2459
Georg Brandl3ee81df2008-05-17 18:14:43 +00002460- Issue #1303614: don't expose object's __dict__ when the dict is

2462
Vinay Sajip8549ce32007-05-06 17:53:37 +00002463- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002464 setting a plain string, ie don't expand to single letter identifiers.
2465
Raymond Hettinger13936692007-04-11 18:40:58 +00002466- Request #1191699: Slices can now be pickled.
2467
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002468- Request #1193128: str.translate() now allows a None argument for
2469 translations that only remove characters without re-mapping the
2470 remaining characters.
2471
Georg Brandl5cb76c12007-03-21 09:00:39 +00002472- Patch #1682205: a TypeError while unpacking an iterable is no longer
2473 masked by a generic one with the message "unpack non-sequence".
2474
Neal Norwitzaa754b72007-03-21 06:39:48 +00002475- Remove unused file Python/fmod.c.
2476
Guido van Rossum143b5642007-03-23 04:58:42 +00002477- Bug #1683368: The object.__init__() and object.__new__() methods are
2478 now stricter in rejecting excess arguments. The only time when
2479 either allows excess arguments is when it is not overridden and the
2480 other one is. For backwards compatibility, when both are
2481 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002482 warning later). Also, type.__init__() insists on the same signature
2483 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002485- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2486 object to complex using its __complex__() method before falling back
2487 to the __float__() method. Therefore, the functions in the cmath
2488 module now can operate on objects that define a __complex__()
2489 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002490
Georg Brandl3ee81df2008-05-17 18:14:43 +00002491- Patch #1623563: allow __class__ assignment for classes with

2508 case, even when converting the value to a string failed.
2509
Georg Brandl871f1bc2007-03-12 13:17:36 +00002510- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002511 its argument, if it exists. If not, it will work like before. This
2512 allows customizing the output of dir() in the presence of a
2513 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002525- Patch #703779: unset __file__ in __main__ after running a file. This

2596 embedded in the string to convert.
2597
Georg Brandl846f73a2006-10-08 07:11:54 +00002598- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00002628- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002646 generator expressions (x for x, in ... ) works again. Fixing this
2647 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00002687- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00003078 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00003563 time so that opening a database previously created with the DB_DUP
3564 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3565 opens. Specifically: dictionary assignment to a DB object will
3566 replace all values for a given key when the database allows
3567 duplicate values. DB users should use DB.put(k, v) when they want
3568 to store duplicates; not DB[k] = v.

3575 characters with ASCII value less than 32. Also, it correctly quotes
3576 dots only if they occur on a single line, as opposed to the previous
3577 behavior of quoting dots if they are the second character of any
3578 line.
