11
12Core and Builtins
13-----------------
14
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +000015- Issue #6289: Encoding errors from compile() were being masked.
16
Benjamin Petersona72be3b2009-06-13 20:23:33 +000017- When no module is given in a relative import, the module field of the
18 ImportFrom AST node is now None instead of an empty string.
19
Benjamin Peterson565e1b62009-06-13 03:46:30 +000020- Assignment to None using import statements now raises a SyntaxError.
21
Benjamin Peterson4afbba32009-06-13 01:40:00 +000022- In the slice AST type, the step field will always be None if a step expression
23 is not specified.
24
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +000025- Issue #4547: When debugging a very large function, it was not always
26 possible to update the lineno attribute of the current frame.
27
Antoine Pitrou46dbe272009-05-30 21:27:00 +000028- Issue #5330: C functions called with keyword arguments were not reported by
29 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
30
Raymond Hettinger578a2282009-05-29 04:58:52 +000031- Issue #5982: staticmethod and classmethod now expose the wrapped
32 function with __func__.
33
Raymond Hettinger822b87f2009-05-29 01:46:48 +000034- Added support for multiple context managers in the same with-statement.
35 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +000036
Benjamin Peterson1880d8b2009-05-25 13:13:44 +000037- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
38 statement and correctly lookup the __enter__ and __exit__ special methods.
39
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000040- Issue #5829: complex("1e500") no longer raises OverflowError. This
41 makes it consistent with float("1e500") and interpretation of real
42 and imaginary literals.
43
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +000044- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
45
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +000046- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
47 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +000048
R. David Murray525cffc2009-05-13 13:07:14 +000049- Issue #5994: the marshal module now has docstrings.
50
Mark Dickinsonb1d45852009-05-11 15:33:08 +000051- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
52 (1) inf and nan strings with trailing whitespace were incorrectly
53 rejected; (2) parsing of strings representing infinities and nans
54 was locale aware; and (3) the interpretation of fromhex('-nan')
55 didn't match that of float('-nan').
56
Eric Smitha985a3a2009-05-05 18:26:08 +000057- Issue #5920: For float.__format__, change the behavior with the
58 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
59 to be like 'g' but with at least one decimal point and with a
60 default precision of 12. Previously, the behavior the same but with
61 a default precision of 6. This more closely matches str(), and
62 reduces surprises when adding alignment flags to the empty
63 presentation type. This also affects the new complex.__format__ in
64 the same way.
65
R. David Murray7ba8e1c2009-05-04 22:16:24 +000066- Issue #5890: in subclasses of 'property' the __doc__ attribute was
67 shadowed by classtype's, even if it was None. property now
68 inserts the __doc__ into the subclass instance __dict__.
69
Antoine Pitrou653dece2009-05-04 18:32:32 +000070- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
71 sequences. Patch by Nick Barnes and Victor Stinner.
72
Vinay Sajipf9b01fe2009-05-09 12:07:17 +000073- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +000074 format(complex(1, 2./3), '.5') now produces a sensible result.
75
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000076- Issue #5864: Fix empty format code formatting for floats so that it
77 never gives more than the requested number of significant digits.
78
Eric Smithcac7af62009-04-27 19:04:37 +000079- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
80 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
81
Martin v. Löwis99f27792009-04-26 00:53:18 +000082- Issue #4971: Fix titlecase for characters that are their own
83 titlecase, but not their own uppercase.
84
Eric Smith068f0652009-04-25 21:40:15 +000085- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
86 _PyOS_double_to_string or PyOS_double_to_string.
87
Benjamin Peterson5083dc52009-04-25 00:41:22 +000088- Issue #5283: Setting __class__ in __del__ caused a segfault.
89
Mark Dickinson95bc9802009-04-24 12:46:53 +000090- Issue #5816: complex(repr(z)) now recovers z exactly, even when
91 z involves nans, infs or negative zeros.
92
Eric Smithaca19e62009-04-22 13:29:05 +000093- Implement PEP 378, Format Specifier for Thousands Separator, for
94 floats, ints, and longs.
95
96- Issue #5515: 'n' formatting for ints, longs, and floats handles
97 leading zero formatting poorly.
98
99- Issue #5772: For float.__format__, don't add a trailing ".0" if
100 we're using no type code and we have an exponent.
101
Mark Dickinson6736cf82009-04-20 21:13:33 +0000102- Issue #3166: Make long -> float (and int -> float) conversions
103 correctly rounded.
104
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000105- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
106 some builtin types.
107
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000108- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000109 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000110
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000111- Issue #5759: float() didn't call __float__ on str subclasses.
112
Georg Brandl3c4a5462009-04-12 12:08:12 +0000113- Issue #5704: the "-3" command-line option now implies "-t".
114
R. David Murray0374a822009-04-09 21:54:50 +0000115- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
116 its clarity and its speed.
117
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000118- Issue #2396: the memoryview object was backported from Python 3.1.

124
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000125- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
126 the end sys.path, for compatibility with the system install of Python.
127
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000128- Issue #4688: Add a heuristic so that tuples and dicts containing only
129 untrackable objects are not tracked by the garbage collector. This can
130 reduce the size of collections and therefore the garbage collection overhead
131 on long-running programs, depending on their particular use of datatypes.
132
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000133- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
134 improve its performance. Long divisions and remainder operations
135 are now between 50% and 150% faster.
136
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000137- Issue #4258: Make it possible to use base 2**30 instead of base
138 2**15 for the internal representation of integers, for performance
139 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
140 --enable-big-digits option to configure, which overrides the
141 default. Add sys.long_info structseq to provide information about
142 the internal format.
143
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000144- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
145 result traceback.__members__ no longer exists.)
146
Mark Dickinson6b265f12009-03-18 16:07:26 +0000147- Issue #4474: PyUnicode_FromWideChar now converts characters outside
148 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
149 and sizeof(Py_UNICODE) == 2.
150
Eric Smith6f42edb2009-03-14 11:57:26 +0000151- Issue #5237: Allow auto-numbered fields in str.format(). For
152 example: '{} {}'.format(1, 2) == '1 2'.
153
Brett Cannon6c4cff02009-03-11 04:51:06 +0000154- Issue #3652: Make the 'line' argument for warnings.showwarning() a
155 requirement. Means the DeprecationWarning from Python 2.6 can go away.
156
Eric Smithe9fb6862009-02-20 14:02:36 +0000157- Issue #5247: Improve error message when unknown format codes are
158 used when using str.format() with str, unicode, long, int, and
159 float arguments.
160
Raymond Hettinger08259e82009-02-18 23:10:19 +0000161- Running Python with the -3 option now also warns about classic division
162 for ints and longs.
163
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000164- Issue #5260: Long integers now consume less memory: average
165 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
166 on a 64-bit system.
167
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000168- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
169 rotating the object pointer by 4 bits to the right.
170
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000171- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
172 it now forces its argument to double before testing for infinity.
173
Benjamin Petersone18ef192009-01-20 14:21:16 +0000174- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
175
Georg Brandl29c6a282009-04-05 20:23:13 +0000176- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000177 were suppressing all exceptions. These include list(), filter(), map(),
178 zip(), and bytearray().
179
Benjamin Peterson596d3062009-01-19 15:42:23 +0000180- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
181 functions.
182
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000183- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
184 OSError.
185

187
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000188- Issue #4935: The overflow checking code in the expandtabs() method common
189 to str, bytes and bytearray could be optimized away by the compiler, letting
190 the interpreter segfault instead of raising an error.
191
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000192- Issue #3720: Fix a crash when an iterator modifies its class and removes its
193 __next__ method.
194

198
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000199- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
200 collecting the oldest generation) so that allocating lots of objects without
201 destroying them does not show quadratic performance. Based on a proposal by
202 Martin von Löwis at
203 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
204
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000205- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
206
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000207- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
208 an existing .py counterpart, override the co_filename attributes of all
209 code objects if the original filename is obsolete (which can happen if the
210 file has been renamed, moved, or if it is accessed through different paths).
211 Patch by Ziga Seilnacht and Jean-Paul Calderone.
212
Martin v. Löwis5344c992009-01-02 20:32:55 +0000213- Issue #4075: Use OutputDebugStringW in Py_FatalError.
214
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000215- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
216 file with `str' filename on Windows.
217

219 did not get collected.
220
Nick Coghlan180e4002008-12-30 01:18:48 +0000221- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
222 where the tp_hash and tp_dict slots are both NULL.
223
Benjamin Peterson7af65562008-12-29 17:56:58 +0000224- Issue #4764: With io.open, IOError.filename is set when trying to open a
225 directory on POSIX systems.
226
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000227- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
228 systems.
229
Georg Brandl6425a2f2008-12-28 11:54:53 +0000230- Issue #4759: None is now allowed as the first argument of

234 fail.
235
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000236- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
237 print elapsed times, not only when some objects are uncollectable /
238 unreachable. Original patch by Neil Schemenauer.
239
Mark Dickinson1a707982008-12-17 16:14:37 +0000240- Issue #3439: Add a bit_length method to int and long.

244
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000245- Issue #4597: Fixed exception handling when the __exit__ function of a
246 context manager returns a value that cannot be converted to a bool.
247
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000248- Issue #4597: Fixed several opcodes that weren't always propagating
249 exceptions.
250
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000251- Issue #4445: Replace "sizeof(PyStringObject)" with
252 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
253 str instances. On a typical machine this saves 3 bytes of memory
254 (on average) per string allocation.
255
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000256- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
257 interpreter to abort ("Fatal Python error: Could not reset the stack!")
258 instead of throwing a MemoryError.
259
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000260- Issue #3689: The list reversed iterator now supports __length_hint__

262
Benjamin Petersonc078f922008-11-21 22:27:24 +0000263- Issue #4367: Python would segfault during compiling when the unicodedata
264 module couldn't be imported and \N escapes were present.
265
Vinay Sajip213faca2008-12-03 23:22:58 +0000266- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000267 method on file objects with closefd=False. The file descriptor is still
268 kept open but the file object behaves like a closed file. The ``FileIO``
269 object also got a new readonly attribute ``closefd``.
270
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000271- Issue #4348: Some bytearray methods returned that didn't cause any change to
272 the bytearray, returned the same bytearray instead of a copy.
273
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000274- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
275
Benjamin Peterson273c2332008-11-17 22:39:09 +0000276- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
277
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000278- Issue #4048: The parser module now correctly validates relative imports.
279
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000280- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
281 exec statement.
282
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000283- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
284 method does not return iterators for the 4th and 5th items.
285
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000286- Issue #4209: Enabling unicode_literals and the print_function in the same
287 __future__ import didn't work.
288
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000289- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000290 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000291
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000292- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
293 returned a path longer than MAX_PATH. (But It's doubtful this code path is
294 really executed because I cannot move to such directory on win2k)
295
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000296- Issue #4069: When set.remove(element) is used with a set element, the element
297 is temporarily replaced with an equivalent frozenset. But the eventual
298 KeyError would always report the empty frozenset([]) as the missing key. Now
299 it correctly refers to the initial element.
300
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000301- Issue #4509: Various issues surrounding resize of bytearray objects to
302 which there are buffer exports.
303

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001278- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1279
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001280- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1281 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1282 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1283 ``printf`` function, whereas PyString_FromFormat has an independent
1284 implementation and uses "%zd" on all platforms for size_t values.
1285 This makes a difference on win64, where ``printf`` needs "%Id" to display
1286 64bit values.
1287
Benjamin Peterson97179b02008-09-09 20:55:01 +00001288- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1292 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001296- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001302 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001303 was correctly parsed but parsing of subsequent arguments failed.
1304
Vinay Sajip35e3b032008-09-01 14:33:59 +00001305- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001306 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1307 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1308 when given a tuple of classes as second argument, were looking up
1309 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1310 type object.
1311
Neal Norwitz18aa3882008-08-24 05:04:52 +00001312- Fix crashes on memory allocation failure found with failmalloc.
1313
1314- Fix memory leaks found with valgrind and update suppressions file.
1315
1316- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00001438- Issue #3833: Use a different upgrade code for Win64 installers.
1439
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001440- Issue #2271: Set SecureCustomProperties so that installation will properly
1441 use the TARGETDIR even for unprivileged users.
1442
Martin v. Löwis67543a92008-09-08 12:02:45 +00001443- Allow passing the MSI file name to merge.py.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001449What's New in Python 2.6 beta 3?
1450================================
1451
Barry Warsaw07a4a382008-08-21 01:15:08 +00001452*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001453
1454Core and Builtins
1455-----------------
1456
Guido van Rossumf8402962008-08-20 15:01:50 +00001457- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1458 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1459 extensions do not automatically benefit from the class attribute
1460 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1461 to their tp_flags field if they care. This is a backwards
1462 compatibility feature; in 3.0, all types will use the cache by
1463 default.
1464
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001465- Keyword arguments can now follow starred arguments. (``f(a, *args,
1466 keyword=23)`` is now valid syntax.)
1467
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001468- ctypes function pointers that are COM methods have a boolean True
1469 value again.
1470
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001471- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1472 by denying s# to parse objects that have a releasebuffer procedure,
1473 and introducing s*.
1474
Georg Brandl1e13ea92008-08-11 09:07:59 +00001475- Issue #3537: Fix an assertion failure when an empty but presized dict
1476 object was stored in the freelist.
1477
Mark Dickinsonb6467572008-08-04 21:30:09 +00001478- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1479 ValueError consistently across platforms.
1480
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001481- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1482 (64bit Unix, for example), unichr() would truncate its argument and return
1483 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1484
Neal Norwitze7d8be82008-07-31 17:17:14 +00001485- Apply security patches from Apple.
1486
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001487- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1488 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1489
Antoine Pitrou92f82162008-07-25 22:22:08 +00001490- Issue #1819: function calls with several named parameters are now on
1491 average 35% faster (as measured by pybench).
1492
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001493- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1494 the python debugger steps into a class statement: the free variables (local
1495 variables defined in an outer scope) would be deleted from the outer scope.
1496
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001497- Issue #2620: Overflow checking when allocating or reallocating memory
1498 was not always being done properly in some python types and extension
1499 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1500 all been updated to perform better checks and places in the code that
1501 would previously leak memory on the error path when such an allocation
1502 failed have been fixed.
1503
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001504Library
1505-------
1506
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001507- Issue #3612: Added some missing basic types in ctypes.wintypes.
1508
Benjamin Petersone977ad42008-08-20 01:42:01 +00001509- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1510 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1511
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001512- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1513 version reported by these tools does not necessarily follow the python
1514 version numbering scheme, so the module is less strict when parsing it.
1515
Nick Coghlanf70385a2008-08-18 12:42:46 +00001516- Issue #2235: Added Py3k warnings for types which will become unhashable
1517 under the stricter __hash__ inheritance rules in 3.0. Several types
1518 which did not meet the rules for hash invariants and were already
1519 unhashable in 3.0 have now been explicitly flagged as unhashable in
1520 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1521 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1522
Brett Cannon88f801d2008-08-18 00:46:22 +00001523- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1524 imported into the module but exposed as part of the module's API.
1525
Brett Cannon7b96f072008-08-18 00:41:11 +00001526- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1527
Brett Cannon46225e72008-08-18 00:36:52 +00001528- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1529
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001530- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1531
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001532- Issue #3575: Incremental decoder's decode function now takes bytearray
1533 by using 's*' instead of 't#'.
1534
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001535- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001536 fails unicode conversion on 2nd parameter. (windows only)
1537
Facundo Batista94f243a2008-08-17 03:38:39 +00001538- Issue 2464. urllib2 now supports a malformation in the URL received
1539 in a redirect.
1540
Brett Cannonabe423e2008-08-16 21:47:07 +00001541- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001542 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001543
Facundo Batistaeb90b782008-08-16 14:44:07 +00001544- Issue #2776: fixed small issue when handling an URL with double slash
1545 after a 302 response in the case of not going through a proxy.
1546
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001547- Issue #2676: in the email package, content-type parsing was hanging on
1548 pathological input because of quadratic or exponential behaviour of a
1549 regular expression.
1550
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001551- Issue #3476: binary buffered reading through the new "io" library is now
1552 thread-safe.
1553
Brett Cannonbf3157b2008-08-14 05:00:03 +00001554- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1555 since mimetools itself is deprecated. Because modules are cached, all
1556 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1557
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001558- Issue #3134: shutil referenced undefined WindowsError symbol.
1559
Robert Schuppenies14646332008-08-10 11:01:53 +00001560- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1561 menu entries were not deleted.
1562
Brett Cannon83e81842008-08-09 23:30:55 +00001563- Copied the implementation of reduce() to _functools.reduce() to have a
1564 version that did not raise a DeprecationWarning under -3.
1565
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001566- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1567 a MemoryError rather than silently stop the iteration.
1568
Guido van Rossum59ce9012008-08-09 14:55:34 +00001569- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1570 to _sre.compile() will now be rejected. This should not affect anybody
1571 since the re.compile() function never generates invalid re-bytecode.
1572
Skip Montanaroa032bf42008-08-08 22:52:51 +00001573- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1574 upon first access it can be automatically initialized from the csv file if
1575 it wasn't initialized during instantiation.
1576
Brett Cannon3aa2a492008-08-06 22:28:09 +00001577- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1578 the reload() built-in has been removed.
1579
Brett Cannon7e30b672008-08-04 21:52:25 +00001580- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001581 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001582 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1583 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1584 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1585 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1586 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001587
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001588- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1589 raised an AttributeError.
1590
Benjamin Peterson01a24322008-07-28 23:35:27 +00001591- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001592 asking for a specific length. This problem only affected files opened
1593 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001594
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001595- Issue #3449: Update decimal module to use most recent specification
1596 (v. 1.68) and tests (v. 2.58) from IBM.
1597
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001598- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1606
1607- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1608 invalid arguments.
1609
1610- Issue #3302: Fix several crashes when calling locale's gettext functions
1611 with None arguments.
1612
1613- Issue #3389: Allow resolving dotted names for handlers in logging
1614 configuration files.
1615
1616- Deprecate the sunaudio module for removal in Python 3.0.
1617
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001618- Issue #3394: zipfile.writestr sets external attributes when passed a
1619 file name rather than a ZipInfo instance, so files are extracted with
1620 mode 0600 rather than 000 under Unix.
1621
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001622- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1623 argument in python 2.5, this broke code that subclassed Popen to include its
1624 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1632-------------
1633
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001634- Issue #2235: the C API function PyObject_HashNotImplemented and its
1635 interaction with the tp_hash slot (added in 2.6b2) are now documented
1636
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001637- Issue #643841: The language reference now provides more detailed
1638 coverage of the lookup process for special methods. The disclaimers
1639 regarding lack of coverage of new-style classes have also been
1640 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001643What's New in Python 2.6 beta 2?
1644================================
1645
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001646*Release date: 17-Jul-2008*

1649-----------------
1650
Georg Brandl3e483f62008-07-16 22:57:41 +00001651- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1652 its methods now allow for items objects that can be converted to
1653 an integer using operator.index().
1654
Mark Dickinson64b7e502008-07-16 09:40:03 +00001655- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1656 produced a ValueError instead of giving the correct float.
1657
Eric Smitha5fa5a22008-07-16 00:11:49 +00001658- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1659 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1660
Mark Dickinson7103aa42008-07-15 19:08:33 +00001661- Issue #3008: the float type has a new instance method 'float.hex'
1662 and a new class method 'float.fromhex' to convert floating-point
1663 numbers to and from hexadecimal strings, respectively.
1664
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001665- Issue #2235: __hash__ is once again inherited by default. To allow
1666 collections.Hashable to remain meaningful in the presence of the
1667 default hash implementation (object.__hash__), it is now possible
1668 to explicit block inheritance of hash by setting __hash__=None at
1669 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1670 level.
1671
Nick Coghlanb028f502008-07-13 14:52:36 +00001672- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1673 the parent module cannot be found while performing an absolute import.
1674 This means that an incorrectly defined __package__ attribute will
1675 now only prevent relative imports in that module rather than causing
1676 all imports from that module to fail.
1677
Nick Coghlan14ff9942008-07-08 14:21:42 +00001678- Issue #2517: Allow unicode messages in Exceptions again by correctly
1679 bypassing the instance dictionary when looking up __unicode__ on
1680 new-style classes.
1681
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001682- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1683 set to a custom object whose write() method happens to install
1684 another file in sys.stdout.
1685
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001686- Issue #3088: Corrected a race condition in classes derived from
1687 threading.local: the first member set by a thread could be saved in
1688 another thread's dictionary.
1689
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001690- Issue #3004: Minor change to slice.indices(): the start and stop
1691 arguments are now treated identically, making the behaviour easier
1692 to describe and understand. For example, slice(None, -10,
1693 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1694 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1695 10, -1).
1696
Georg Brandl278fc502008-07-19 12:46:12 +00001697- Issue #3219: Calling a function with repeated keyword arguments,
1698 f(a=2, a=23), would not cause a syntax error. This was a regression
1699 from 2.4 caused by the switch to the new compiler.

1709 api functions without holding the GIL, which could lead to a fatal
1710 error when they failed.
1711
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001712- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2148 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002149 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002150
2151 This is controlled by the configure argument ``--with-universal-archs``:
2152
2153 - ``--with-universal-archs=all``: install 4-way universal
2154
2155 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2156
2157 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2158
2159 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002211- Issue #1631171: Re-implement the 'warnings' module in C (the
2212 original Python code has been kept as backup). This will allow for
2213 using the 'warning's machinery in such places as the parser where
2214 use of pure Python code is not possible. Both the ``showarning()``
2215 and ``formatwarning()`` gain an optional 'line' argument which is
2216 not called by default for backwards-compatibility reasons. Setting
2217 ``warnings.showwarning()`` to an implementation that lacks support
2218 for the ``line`` argument will raise a DeprecationWarning.

2242
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002243- The getpass module has been improved on Unix. It now uses /dev/tty
2244 by default and uses stderr instead of stdout. A GetPassWarning is
2245 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002246

Georg Brandl3ee81df2008-05-17 18:14:43 +00002260- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002261 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002281- Issue #2550: The approach used by client/server code for obtaining
2282 ports to listen on in network-oriented tests has been refined in an
2283 effort to facilitate running multiple instances of the entire
2284 regression test suite in parallel without issue.
2285 test_support.bind_port() has been fixed such that it will always
2286 return a unique port -- which wasn't always the case with the
2287 previous implementation, especially if socket options had been set
2288 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2289 new implementation of bind_port() will actually raise an exception
2290 if it is passed an AF_INET/SOCK_STREAM socket with either the
2291 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2292 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2293 the socket it's been passed. This currently only applies to
2294 Windows. This option prevents any other sockets from binding to the
2295 host/port we've bound to, thus removing the possibility of the
2296 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2297 when a second SOCK_STREAM socket binds and accepts to a host/port
2298 that's already been bound by another socket. The optional preferred
2299 port parameter to bind_port() has been removed. Under no
2300 circumstances should tests be hard coding ports!
2301
2302 test_support.find_unused_port() has also been introduced, which will
2303 pass a temporary socket object to bind_port() in order to obtain an
2304 unused port. The temporary socket object is then closed and
2305 deleted, and the port is returned. This method should only be used
2306 for obtaining an unused port in order to pass to an external program
2307 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2308 a parameter to a server-oriented class that doesn't give you direct
2309 access to the underlying socket used.
2310
2311 Finally, test_support.HOST has been introduced, which should be used
2312 for the host argument of any relevant socket calls (i.e. bind and
2313 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002314
2315 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002316 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002317 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2318 test_asynchat and test_socket_ssl.
2319
Georg Brandl3ee81df2008-05-17 18:14:43 +00002320 It is now possible for multiple instances of the regression test
2321 suite to run in parallel without issue.

2587Core and builtins
2588-----------------
2589
Fred Drakea8ee94b2008-03-01 02:45:07 +00002590- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002591 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002592
Georg Brandlad61bc82008-02-23 15:11:18 +00002593- Issue #2067: file.__exit__() now calls subclasses' close() method.
2594
2595- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002596
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002597- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002598 issue 215555 for a discussion.
2599
Eric Smitha73fbe72008-02-23 03:09:44 +00002600- Added the future_builtins module, which contains hex() and oct().
2601 These are the PEP 3127 version of these functions, designed to be
2602 compatible with the hex() and oct() builtins from Python 3.0. They
2603 differ slightly in their output formats from the existing, unchanged
2604 Python 2.6 builtins. The expected usage of the future_builtins
2605 module is:
2606 from future_builtins import hex, oct
2607
Eric Smith7ef40bf2008-02-20 23:34:22 +00002608- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2609 exponents for exponents with absolute value < 100. Follows C99
2610 standard. This is a change on Windows, which would use 3 digits.
2611 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2612 so that any alterations it does to the resulting string will be
2613 available in stringlib/formatter.h (for float.__format__).
2614
Eric Smith5a3c1352008-02-19 13:21:56 +00002615- Implemented PEP 3101, Advanced String Formatting. This adds a new
2616 builtin format(); a format() method for str and unicode; a
2617 __format__() method to object, str, unicode, int, long, float, and
2618 datetime; the class string.Formatter; and the C API
2619 PyObject_Format().
2620
Georg Brandl3ee81df2008-05-17 18:14:43 +00002621- Fixed several potential crashes, all caused by specially crafted
2622 __del__ methods exploiting objects in temporarily inconsistent
2623 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002624
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002625- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002626 prevent a possible crash: an Abstract Base Class would try to access
2627 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002628
Georg Brandl3ee81df2008-05-17 18:14:43 +00002629- Fixed repr() and str() of complex numbers with infinity or nan as
2630 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002631
Georg Brandl3ee81df2008-05-17 18:14:43 +00002632- Clear all free lists during a gc.collect() of the highest generation
2633 in order to allow pymalloc to free more arenas. Python may give back
2634 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002635
Georg Brandl3ee81df2008-05-17 18:14:43 +00002636- Issue #2045: Fix an infinite recursion triggered when printing a
2637 subclass of collections.defaultdict, if its default_factory is set
2638 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002639
Christian Heimesf75dbef2008-02-08 00:11:31 +00002640- Fixed a minor memory leak in dictobject.c. The content of the free
2641 list was not freed on interpreter shutdown.
2642
Georg Brandl3ee81df2008-05-17 18:14:43 +00002643- Limit free list of method and builtin function objects to 256
2644 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002645
Georg Brandl3ee81df2008-05-17 18:14:43 +00002646- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2647 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002648 to compact the internal free lists of pre-allocted ints and floats.
2649
Georg Brandl3ee81df2008-05-17 18:14:43 +00002650- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2651 calls. Python expected the return type int but the fork familie
2652 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002653
Georg Brandl3ee81df2008-05-17 18:14:43 +00002654- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2655 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002656
Georg Brandl3ee81df2008-05-17 18:14:43 +00002657- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2658 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002659
Georg Brandl3ee81df2008-05-17 18:14:43 +00002660- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2661 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002662
Georg Brandl3ee81df2008-05-17 18:14:43 +00002663- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2664 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002665
Georg Brandl3ee81df2008-05-17 18:14:43 +00002666- Patch #1473257: generator objects gain a gi_code attribute. This is
2667 the same object as the func_code attribute of the function that
2668 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002669
Georg Brandl3ee81df2008-05-17 18:14:43 +00002670- Issue #1920: "while 0" statements were completely removed by the
2671 compiler, even in the presence of an "else" clause, which is
2672 supposed to be run when the condition is false. Now the compiler
2673 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002674
Guido van Rossumeead05f2008-01-24 18:21:02 +00002675- A few crashers fixed: weakref_in_del.py (issue #1377858);
2676 loosing_dict_ref.py (issue #1303614, test67.py);
2677 borrowed_ref_[34].py (not in tracker).
2678
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002679- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002680 suppressed while an extension is loaded by calling SetErrorMode in
2681 dynload_win.c. The error is still reported properly.
2682
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002684 several extension methods and modules do not work without unicode
2685 support.
2686
Georg Brandl26543b12008-01-21 18:36:51 +00002687- Issue #1882: when compiling code from a string, encoding cookies in the
2688 second line of code were not always recognized correctly.
2689
Georg Brandl14404b62008-01-19 19:27:05 +00002690- Issue #1679: "0x" was taken as a valid integer literal.
2691
Georg Brandl6caad7d2008-01-26 14:19:22 +00002692- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002693 added.
2694
Christian Heimesc94e2b52008-01-14 04:13:37 +00002695- sys.float_info / PyFloat_GetInfo: The floating point information
2696 object was converted from a dict to a specialized structseq object.
2697
Georg Brandl3ee81df2008-05-17 18:14:43 +00002698- Patch #1816: Added sys.flags structseq. It exposes the status of
2699 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Objects/structseq.c: Implemented new structseq representation. The
2702 patch makes structseqs (e.g. the return value of os.stat) more
2703 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002704
Georg Brandl3ee81df2008-05-17 18:14:43 +00002705- Patch #1700288: added a type attribute cache that caches method
2706 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002707
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002708- Bug #1776: __import__() no longer accepts filenames on any platform.

2714 envvar and sys.dont_write_bytecode attribute. All these can be set
2715 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002716
Georg Brandl3ee81df2008-05-17 18:14:43 +00002717- Improve some exception messages when Windows fails to load an
2718 extension module. Now we get for example '%1 is not a valid Win32
2719 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002720
Georg Brandl3ee81df2008-05-17 18:14:43 +00002721- Bug #1481296: Fixed long(float('nan')) != 0L.

2724 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002725
Christian Heimes0a8143f2007-12-18 23:22:54 +00002726- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002727 and INF. float("nan"), float("inf") and float("-inf") now work on
2728 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002729
Georg Brandl3ee81df2008-05-17 18:14:43 +00002730- Compiler now generates simpler and faster code for dictionary
2731 literals. The oparg for BUILD_MAP now indicates an estimated
2732 dictionary size. There is a new opcode, STORE_MAP, for adding
2733 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002777- The enumerate() builtin function is no longer bounded to sequences
2778 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2779 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002780
Georg Brandl3ee81df2008-05-17 18:14:43 +00002781- Issue #1686386: Tuple's tp_repr did not take into account the
2782 possibility of having a self-referential tuple, which is possible
2783 from C code. Nor did object's tp_str consider that a type's tp_str
2784 could do something that could lead to an inifinite recursion.
2785 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2786 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002788- Issue #1164: It was possible to trigger deadlock when using the
2789 'print' statement to write to a file since the GIL was not released
2790 as needed. Now PyObject_Print() does the right thing along with
2791 various tp_print implementations of the built-in types and those in
2792 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002793
Georg Brandl3ee81df2008-05-17 18:14:43 +00002794- Issue #1147: Exceptions were directly allowing string exceptions in
2795 their throw() method even though string exceptions no longer
2796 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002797
Georg Brandl3ee81df2008-05-17 18:14:43 +00002798- Issue #1096: Prevent a segfault from getting the repr of a very
2799 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002800
Brett Cannon1e534b52007-09-07 04:18:30 +00002801- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802 PyObject_Call() never calling back out to Python code to trigger
2803 recursion depth updates/checks. Required the creation of a static
2804 RuntimeError instance in case normalizing an exception put the
2805 recursion check value past its limit. Fixes crashers
2806 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Patch #1031213: Decode source line in SyntaxErrors back to its

Georg Brandl7c3b50d2007-07-12 08:38:00 +00002811- Patch #1673759: add a missing overflow check when formatting floats
2812 with %G.
2813
Georg Brandl3ee81df2008-05-17 18:14:43 +00002814- Prevent expandtabs() on string and unicode objects from causing a
2815 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002816

Martin v. Löwisda587ab2007-06-08 17:29:20 +00002818
Georg Brandl3ee81df2008-05-17 18:14:43 +00002819- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00002820
Neal Norwitz0ac60192007-05-27 04:08:54 +00002821- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002822 __*__ attributes. (Some already existed, e.g., __doc__ and
2823 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002824
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002825- Add -3 option to the interpreter to warn about features that are
2826 deprecated and will be changed/removed in Python 3.0.
2827
Georg Brandl2134e752007-05-21 20:34:16 +00002828- Patch #1686487: you can now pass any mapping after '**' in function
2829 calls.
2830
Collin Winter62903052007-05-18 23:11:24 +00002831- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002832 "except E as target:". This is to provide forwards compatibility
2833 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002834
Brett Cannon229cee22007-05-05 01:34:02 +00002835- Deprecate BaseException.message as per PEP 352.
2836
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002838 inherited from a builtin base.
2839
Vinay Sajip8549ce32007-05-06 17:53:37 +00002840- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002841 setting a plain string, ie don't expand to single letter identifiers.
2842
Raymond Hettinger13936692007-04-11 18:40:58 +00002843- Request #1191699: Slices can now be pickled.
2844
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002845- Request #1193128: str.translate() now allows a None argument for
2846 translations that only remove characters without re-mapping the
2847 remaining characters.
2848
Georg Brandl5cb76c12007-03-21 09:00:39 +00002849- Patch #1682205: a TypeError while unpacking an iterable is no longer
2850 masked by a generic one with the message "unpack non-sequence".
2851
Neal Norwitzaa754b72007-03-21 06:39:48 +00002852- Remove unused file Python/fmod.c.
2853
Guido van Rossum143b5642007-03-23 04:58:42 +00002854- Bug #1683368: The object.__init__() and object.__new__() methods are
2855 now stricter in rejecting excess arguments. The only time when
2856 either allows excess arguments is when it is not overridden and the
2857 other one is. For backwards compatibility, when both are
2858 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002859 warning later). Also, type.__init__() insists on the same signature
2860 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002861
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2863 object to complex using its __complex__() method before falling back
2864 to the __float__() method. Therefore, the functions in the cmath
2865 module now can operate on objects that define a __complex__()
2866 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002867
Georg Brandl3ee81df2008-05-17 18:14:43 +00002868- Patch #1623563: allow __class__ assignment for classes with
2869 __slots__. The old and the new class are still required to have the
2870 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002871
Georg Brandl3ee81df2008-05-17 18:14:43 +00002872- Patch #1642547: Fix an error/crash when encountering syntax errors
2873 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002875- Patch #1462488: Python no longer segfaults when
2876 ``object.__reduce_ex__()`` is called with an object that is faking
2877 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002878
Georg Brandl3ee81df2008-05-17 18:14:43 +00002879- Patch #1680015: Don't modify __slots__ tuple if it contains an
2880 unicode name.
Žiga Seilnacht71436f02007-03-14 12:24:09 +00002881
Georg Brandl5240d742007-03-13 20:46:32 +00002882- Patch #1444529: the builtin compile() now accepts keyword arguments.
2883
Georg Brandl7b9c5552007-03-12 14:30:05 +00002884- Bug #1678647: write a newline after printing an exception in any
2885 case, even when converting the value to a string failed.
2886
Georg Brandl871f1bc2007-03-12 13:17:36 +00002887- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888 its argument, if it exists. If not, it will work like before. This
2889 allows customizing the output of dir() in the presence of a
2890 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002891
Collin Winter276887b2007-03-12 16:11:39 +00002892- Patch #922167: Python no longer segfaults when faced with infinitely
2893 self-recursive reload() calls (as reported by bug #742342).
2894
Georg Brandl3ee81df2008-05-17 18:14:43 +00002895- Patch #1675981: remove unreachable code from ``type.__new__()``
2896 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002898- Patch #1491866: change the complex() constructor to allow
2899 parthensized forms. This means complex(repr(x)) now works instead of
2900 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002901
Georg Brandlaa2321b2007-03-07 00:40:28 +00002902- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002903 makes the filenames the warning module prints much more sensible
2904 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002905
Georg Brandl49aafc92007-03-07 00:34:46 +00002906- Variant of patch #697613: don't exit the interpreter on a SystemExit
2907 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002908 variable is given, but break into the interactive interpreter just
2909 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00002910
Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00002914- Bug #1674503: close the file opened by execfile() in an error
2915 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002916
Georg Brandl0fca97a2007-03-05 22:28:08 +00002917- Patch #1674228: when assigning a slice (old-style), check for the
2918 sq_ass_slice instead of the sq_slice slot.
2919
Georg Brandl3ee81df2008-05-17 18:14:43 +00002920- When printing an unraisable error, don't print exceptions. before
2921 the name. This duplicates the behavior whening normally printing
2922 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002923
Georg Brandl3ee81df2008-05-17 18:14:43 +00002924- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002930- Bug #1377858: Fix the segfaulting of the interpreter when an object
2931 created a weakref on itself during a __del__ call for new-style
2932 classes (classic classes still have the bug).
Brett Cannonf5bee302007-01-23 23:21:22 +00002933
Martin v. Löwis6c5c5022007-01-23 21:11:47 +00002934- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
2935 frame's thread state.

2979
Armin Rigo7ccbca92006-10-04 12:17:45 +00002980- A number of places, including integer negation and absolute value,
2981 were fixed to not rely on undefined behaviour of the C compiler
2982 anymore.

2985 number of arguments, as was the case in Python 2.4.
2986
Georg Brandl5d59c092006-09-30 08:43:30 +00002987- Patch #1567691: super() and new.instancemethod() now don't accept
Georg Brandl3ee81df2008-05-17 18:14:43 +00002988 keyword arguments any more (previously they accepted them, but
2989 didn't use them).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002991- Fix a bug in the parser's future statement handling that led to
2992 "with" not being recognized as a keyword after, e.g., this
2993 statement: from __future__ import division, with_statement
Georg Brandla10d3af2006-09-24 12:35:36 +00002994
Neal Norwitz3a230172006-09-22 08:18:10 +00002995- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).

3002 method. This allows calling unicode() on exceptions classes
3003 directly to succeed.
Brett Cannon9adeab72006-09-20 18:34:28 +00003004
Georg Brandl4e933132006-09-06 20:05:58 +00003005- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

3020 head is the original string if sep was not found.
3021
Neal Norwitzdac090d2006-09-05 03:53:08 +00003022- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00003023 generator expressions (x for x, in ... ) works again. Fixing this
3024 problem required changing the .pyc magic number. This means that
3025 .pyc files generated before 2.5c2 will be regenerated.
Neal Norwitzdac090d2006-09-05 03:53:08 +00003026
Georg Brandl6caad7d2008-01-26 14:19:22 +00003027- ``with`` and ``as`` are now keywords.

3531 Python would crash instead of raising an error.
3532

3549 incompatibility since it never made sense with ordinary subclasses
3550 -- the failure just occurred later, with a more cumbersome
3551 exception.

3835 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003838 that the SMTP.starttls() caller no longer needs to call ehlo()
3839 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840 does not claim to support starttls. Adds the

3922 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3923 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003940 time so that opening a database previously created with the DB_DUP
3941 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3942 opens. Specifically: dictionary assignment to a DB object will
3943 replace all values for a given key when the database allows
3944 duplicate values. DB users should use DB.put(k, v) when they want
3945 to store duplicates; not DB[k] = v.

3952 characters with ASCII value less than 32. Also, it correctly quotes
3953 dots only if they occur on a single line, as opposed to the previous
3954 behavior of quoting dots if they are the second character of any
3955 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003956

4278-----
4279
Georg Brandl3ee81df2008-05-17 18:14:43 +00004280- Unified naming convention for free lists and their limits. All free
4281 lists in Object/ are named ``free_list``, the counter ``numfree``
4282 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4283 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004284
Georg Brandl3ee81df2008-05-17 18:14:43 +00004285- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4286 to ``PyTuple_SetItem``, it can be used to populate a brand new
4287 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004288
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004289- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004291- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4292 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4293 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004294
4295- Patch #1720595: add T_BOOL to the range of structmember types.
4296
4297- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4298 ``PyFloat_GetInfo()`` to the float API.
4299
Georg Brandl3ee81df2008-05-17 18:14:43 +00004300- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4301 of w# format code incorrectly truncated the length to an int, even
4302 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4303 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004304
Georg Brandl3ee81df2008-05-17 18:14:43 +00004305- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4306 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004308- PEP 3123: Provide forward compatibility with Python 3.0, while
4309 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4310 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004311
Georg Brandl3ee81df2008-05-17 18:14:43 +00004312- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4313 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004314
4315- Patch #1733960: Allow T_LONGLONG to accept ints.
4316
4317- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4318

4322
4323- Fix some leftovers from the conversion from int to Py_ssize_t
4324 (relevant to strings and sequences of more than 2**31 items).
4325
4326- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4327 outside of pystate.c and should not be necessary.
4328
Georg Brandl3ee81df2008-05-17 18:14:43 +00004329- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4330 absolute imports. In earlier versions they might have used relative
4331 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004332
Georg Brandl3ee81df2008-05-17 18:14:43 +00004333- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4334 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004335
Georg Brandl3ee81df2008-05-17 18:14:43 +00004336- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4342
Georg Brandl3ee81df2008-05-17 18:14:43 +00004343- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4344 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4345 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4346 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004347
Georg Brandl3ee81df2008-05-17 18:14:43 +00004348- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00004359- buildtools now raises a DeprecationWarning.
4360
Georg Brandl3ee81df2008-05-17 18:14:43 +00004361- Removed the macfs module. It had been deprecated since Python 2.5.
4362 This lead to the deprecation of macostools.touched() as it relied
4363 solely on macfs and was a no-op under OS X.
