11
12Core and Builtins
13-----------------
14
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +000015- Issue #4547: When debugging a very large function, it was not always
16 possible to update the lineno attribute of the current frame.
17
Antoine Pitrou46dbe272009-05-30 21:27:00 +000018- Issue #5330: C functions called with keyword arguments were not reported by
19 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
20
Raymond Hettinger578a2282009-05-29 04:58:52 +000021- Issue #5982: staticmethod and classmethod now expose the wrapped
22 function with __func__.
23
Raymond Hettinger822b87f2009-05-29 01:46:48 +000024- Added support for multiple context managers in the same with-statement.
25 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +000026
Benjamin Peterson1880d8b2009-05-25 13:13:44 +000027- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
28 statement and correctly lookup the __enter__ and __exit__ special methods.
29
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000030- Issue #5829: complex("1e500") no longer raises OverflowError. This
31 makes it consistent with float("1e500") and interpretation of real
32 and imaginary literals.
33
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +000034- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
35
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +000036- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
37 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +000038
R. David Murray525cffc2009-05-13 13:07:14 +000039- Issue #5994: the marshal module now has docstrings.
40
Mark Dickinsonb1d45852009-05-11 15:33:08 +000041- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
42 (1) inf and nan strings with trailing whitespace were incorrectly
43 rejected; (2) parsing of strings representing infinities and nans
44 was locale aware; and (3) the interpretation of fromhex('-nan')
45 didn't match that of float('-nan').
46
Eric Smitha985a3a2009-05-05 18:26:08 +000047- Issue #5920: For float.__format__, change the behavior with the
48 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
49 to be like 'g' but with at least one decimal point and with a
50 default precision of 12. Previously, the behavior the same but with
51 a default precision of 6. This more closely matches str(), and
52 reduces surprises when adding alignment flags to the empty
53 presentation type. This also affects the new complex.__format__ in
54 the same way.
55
R. David Murray7ba8e1c2009-05-04 22:16:24 +000056- Issue #5890: in subclasses of 'property' the __doc__ attribute was
57 shadowed by classtype's, even if it was None. property now
58 inserts the __doc__ into the subclass instance __dict__.
59
Antoine Pitrou653dece2009-05-04 18:32:32 +000060- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
61 sequences. Patch by Nick Barnes and Victor Stinner.
62
Vinay Sajipf9b01fe2009-05-09 12:07:17 +000063- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +000064 format(complex(1, 2./3), '.5') now produces a sensible result.
65
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000066- Issue #5864: Fix empty format code formatting for floats so that it
67 never gives more than the requested number of significant digits.
68
Eric Smithcac7af62009-04-27 19:04:37 +000069- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
70 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
71
Martin v. Löwis99f27792009-04-26 00:53:18 +000072- Issue #4971: Fix titlecase for characters that are their own
73 titlecase, but not their own uppercase.
74
Eric Smith068f0652009-04-25 21:40:15 +000075- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
76 _PyOS_double_to_string or PyOS_double_to_string.
77
Benjamin Peterson5083dc52009-04-25 00:41:22 +000078- Issue #5283: Setting __class__ in __del__ caused a segfault.
79
Mark Dickinson95bc9802009-04-24 12:46:53 +000080- Issue #5816: complex(repr(z)) now recovers z exactly, even when
81 z involves nans, infs or negative zeros.
82
Eric Smithaca19e62009-04-22 13:29:05 +000083- Implement PEP 378, Format Specifier for Thousands Separator, for
84 floats, ints, and longs.
85
86- Issue #5515: 'n' formatting for ints, longs, and floats handles
87 leading zero formatting poorly.
88
89- Issue #5772: For float.__format__, don't add a trailing ".0" if
90 we're using no type code and we have an exponent.
91
Mark Dickinson6736cf82009-04-20 21:13:33 +000092- Issue #3166: Make long -> float (and int -> float) conversions
93 correctly rounded.
94
Benjamin Petersond4d400c2009-04-18 20:12:47 +000095- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
96 some builtin types.
97
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000098- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +000099 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000100
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000101- Issue #5759: float() didn't call __float__ on str subclasses.
102
Georg Brandl3c4a5462009-04-12 12:08:12 +0000103- Issue #5704: the "-3" command-line option now implies "-t".
104
R. David Murray0374a822009-04-09 21:54:50 +0000105- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
106 its clarity and its speed.
107
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000108- Issue #2396: the memoryview object was backported from Python 3.1.
109

112
Brett Cannon15ba4da2009-04-01 18:03:59 +0000113- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
114
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000115- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
116 the end sys.path, for compatibility with the system install of Python.
117
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000118- Issue #4688: Add a heuristic so that tuples and dicts containing only
119 untrackable objects are not tracked by the garbage collector. This can
120 reduce the size of collections and therefore the garbage collection overhead
121 on long-running programs, depending on their particular use of datatypes.
122
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000123- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
124 improve its performance. Long divisions and remainder operations
125 are now between 50% and 150% faster.
126
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000127- Issue #4258: Make it possible to use base 2**30 instead of base
128 2**15 for the internal representation of integers, for performance
129 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
130 --enable-big-digits option to configure, which overrides the
131 default. Add sys.long_info structseq to provide information about
132 the internal format.
133
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000134- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
135 result traceback.__members__ no longer exists.)
136
Mark Dickinson6b265f12009-03-18 16:07:26 +0000137- Issue #4474: PyUnicode_FromWideChar now converts characters outside
138 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
139 and sizeof(Py_UNICODE) == 2.
140
Eric Smith6f42edb2009-03-14 11:57:26 +0000141- Issue #5237: Allow auto-numbered fields in str.format(). For
142 example: '{} {}'.format(1, 2) == '1 2'.
143
Brett Cannon6c4cff02009-03-11 04:51:06 +0000144- Issue #3652: Make the 'line' argument for warnings.showwarning() a
145 requirement. Means the DeprecationWarning from Python 2.6 can go away.
146
Eric Smithe9fb6862009-02-20 14:02:36 +0000147- Issue #5247: Improve error message when unknown format codes are
148 used when using str.format() with str, unicode, long, int, and
149 float arguments.
150
Raymond Hettinger08259e82009-02-18 23:10:19 +0000151- Running Python with the -3 option now also warns about classic division
152 for ints and longs.
153
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000154- Issue #5260: Long integers now consume less memory: average
155 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
156 on a 64-bit system.
157
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000158- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
159 rotating the object pointer by 4 bits to the right.
160
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000161- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
162 it now forces its argument to double before testing for infinity.
163
Benjamin Petersone18ef192009-01-20 14:21:16 +0000164- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
165
Georg Brandl29c6a282009-04-05 20:23:13 +0000166- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000167 were suppressing all exceptions. These include list(), filter(), map(),
168 zip(), and bytearray().
169
Benjamin Peterson596d3062009-01-19 15:42:23 +0000170- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

177
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000178- Issue #4935: The overflow checking code in the expandtabs() method common
179 to str, bytes and bytearray could be optimized away by the compiler, letting
180 the interpreter segfault instead of raising an error.
181
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000182- Issue #3720: Fix a crash when an iterator modifies its class and removes its
183 __next__ method.
184

188
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000189- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
190 collecting the oldest generation) so that allocating lots of objects without
191 destroying them does not show quadratic performance. Based on a proposal by
192 Martin von Löwis at
193 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
194
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000195- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
196
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000197- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
198 an existing .py counterpart, override the co_filename attributes of all
199 code objects if the original filename is obsolete (which can happen if the
200 file has been renamed, moved, or if it is accessed through different paths).
201 Patch by Ziga Seilnacht and Jean-Paul Calderone.
202
Martin v. Löwis5344c992009-01-02 20:32:55 +0000203- Issue #4075: Use OutputDebugStringW in Py_FatalError.
204
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000205- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
206 file with `str' filename on Windows.

209 did not get collected.
210
Nick Coghlan180e4002008-12-30 01:18:48 +0000211- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
212 where the tp_hash and tp_dict slots are both NULL.
213
Benjamin Peterson7af65562008-12-29 17:56:58 +0000214- Issue #4764: With io.open, IOError.filename is set when trying to open a
215 directory on POSIX systems.
216
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000217- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
218 systems.
219
Georg Brandl6425a2f2008-12-28 11:54:53 +0000220- Issue #4759: None is now allowed as the first argument of

224 fail.
225
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000226- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
227 print elapsed times, not only when some objects are uncollectable /
228 unreachable. Original patch by Neil Schemenauer.
229
Mark Dickinson1a707982008-12-17 16:14:37 +0000230- Issue #3439: Add a bit_length method to int and long.

236 context manager returns a value that cannot be converted to a bool.
237
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000238- Issue #4597: Fixed several opcodes that weren't always propagating
239 exceptions.
240
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000241- Issue #4445: Replace "sizeof(PyStringObject)" with
242 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
243 str instances. On a typical machine this saves 3 bytes of memory
244 (on average) per string allocation.
245
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000246- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
247 interpreter to abort ("Fatal Python error: Could not reset the stack!")

255
Vinay Sajip213faca2008-12-03 23:22:58 +0000256- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000257 method on file objects with closefd=False. The file descriptor is still
258 kept open but the file object behaves like a closed file. The ``FileIO``
259 object also got a new readonly attribute ``closefd``.
260
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000261- Issue #4348: Some bytearray methods returned that didn't cause any change to
262 the bytearray, returned the same bytearray instead of a copy.
263

267
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000268- Issue #4048: The parser module now correctly validates relative imports.
269
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000270- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
271 exec statement.
272
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000273- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
274 method does not return iterators for the 4th and 5th items.
275
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000276- Issue #4209: Enabling unicode_literals and the print_function in the same
277 __future__ import didn't work.
278
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000279- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000280 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000281
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000282- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
283 returned a path longer than MAX_PATH. (But It's doubtful this code path is
284 really executed because I cannot move to such directory on win2k)
285
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000286- Issue #4069: When set.remove(element) is used with a set element, the element
287 is temporarily replaced with an equivalent frozenset. But the eventual
288 KeyError would always report the empty frozenset([]) as the missing key. Now
289 it correctly refers to the initial element.
290
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000291- Issue #4509: Various issues surrounding resize of bytearray objects to
292 which there are buffer exports.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001237- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1238
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001239- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1240 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1241 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1242 ``printf`` function, whereas PyString_FromFormat has an independent
1243 implementation and uses "%zd" on all platforms for size_t values.
1244 This makes a difference on win64, where ``printf`` needs "%Id" to display
1245 64bit values.
1246
Benjamin Peterson97179b02008-09-09 20:55:01 +00001247- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1251 object; previously an int would be returned for small values. the __long__
1252 method is allowed to return either an int or a long, but the behaviour of
1253 float objects should not change to respect backward compatibility.
1254
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001255- Issue #3751: str.rpartition would perform a left-partition when called with
1256 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001261 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001262 was correctly parsed but parsing of subsequent arguments failed.
1263
Vinay Sajip35e3b032008-09-01 14:33:59 +00001264- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001265 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1266 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1267 when given a tuple of classes as second argument, were looking up
1268 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1269 type object.
1270
Neal Norwitz18aa3882008-08-24 05:04:52 +00001271- Fix crashes on memory allocation failure found with failmalloc.
1272
1273- Fix memory leaks found with valgrind and update suppressions file.
1274
1275- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1340 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1341 for catch_warnings() also led to an improvement in the raising of a

1414-----------------
1415
Guido van Rossumf8402962008-08-20 15:01:50 +00001416- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1417 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1418 extensions do not automatically benefit from the class attribute
1419 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1420 to their tp_flags field if they care. This is a backwards
1421 compatibility feature; in 3.0, all types will use the cache by
1422 default.

1438 ValueError consistently across platforms.
1439
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001440- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1441 (64bit Unix, for example), unichr() would truncate its argument and return
1442 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1443
Neal Norwitze7d8be82008-07-31 17:17:14 +00001444- Apply security patches from Apple.
1445
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001446- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1447 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1448
Antoine Pitrou92f82162008-07-25 22:22:08 +00001449- Issue #1819: function calls with several named parameters are now on
1450 average 35% faster (as measured by pybench).
1451
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001452- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1453 the python debugger steps into a class statement: the free variables (local
1454 variables defined in an outer scope) would be deleted from the outer scope.
1455
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001456- Issue #2620: Overflow checking when allocating or reallocating memory
1457 was not always being done properly in some python types and extension
1458 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1459 all been updated to perform better checks and places in the code that
1460 would previously leak memory on the error path when such an allocation
1461 failed have been fixed.

1467
Benjamin Petersone977ad42008-08-20 01:42:01 +00001468- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1469 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1470
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001471- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1472 version reported by these tools does not necessarily follow the python
1473 version numbering scheme, so the module is less strict when parsing it.
1474
Nick Coghlanf70385a2008-08-18 12:42:46 +00001475- Issue #2235: Added Py3k warnings for types which will become unhashable
1476 under the stricter __hash__ inheritance rules in 3.0. Several types
1477 which did not meet the rules for hash invariants and were already
1478 unhashable in 3.0 have now been explicitly flagged as unhashable in
1479 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1480 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1481
Brett Cannon88f801d2008-08-18 00:46:22 +00001482- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1483 imported into the module but exposed as part of the module's API.
1484

Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001491- Issue #3575: Incremental decoder's decode function now takes bytearray
1492 by using 's*' instead of 't#'.
1493
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001494- Issue #2222: Fixed reference leak when occurred os.rename()

1504 after a 302 response in the case of not going through a proxy.
1505
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001506- Issue #2676: in the email package, content-type parsing was hanging on
1507 pathological input because of quadratic or exponential behaviour of a
1508 regular expression.
1509
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001510- Issue #3476: binary buffered reading through the new "io" library is now
1511 thread-safe.
1512
Brett Cannonbf3157b2008-08-14 05:00:03 +00001513- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1514 since mimetools itself is deprecated. Because modules are cached, all
1515 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1516
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001517- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001519- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1520 menu entries were not deleted.
1521
Brett Cannon83e81842008-08-09 23:30:55 +00001522- Copied the implementation of reduce() to _functools.reduce() to have a
1523 version that did not raise a DeprecationWarning under -3.
1524
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001525- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1526 a MemoryError rather than silently stop the iteration.
1527
Guido van Rossum59ce9012008-08-09 14:55:34 +00001528- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1529 to _sre.compile() will now be rejected. This should not affect anybody
1530 since the re.compile() function never generates invalid re-bytecode.
1531
Skip Montanaroa032bf42008-08-08 22:52:51 +00001532- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1533 upon first access it can be automatically initialized from the csv file if
1534 it wasn't initialized during instantiation.
1535
Brett Cannon3aa2a492008-08-06 22:28:09 +00001536- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1537 the reload() built-in has been removed.
1538
Brett Cannon7e30b672008-08-04 21:52:25 +00001539- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001540 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1548 raised an AttributeError.
1549
Benjamin Peterson01a24322008-07-28 23:35:27 +00001550- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001551 asking for a specific length. This problem only affected files opened
1552 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001553

1576
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001577- Issue #3394: zipfile.writestr sets external attributes when passed a
1578 file name rather than a ZipInfo instance, so files are extracted with
1579 mode 0600 rather than 000 under Unix.
1580
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001581- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1582 argument in python 2.5, this broke code that subclassed Popen to include its
1583 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001593- Issue #2235: the C API function PyObject_HashNotImplemented and its
1594 interaction with the tp_hash slot (added in 2.6b2) are now documented
1595
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001596- Issue #643841: The language reference now provides more detailed
1597 coverage of the lookup process for special methods. The disclaimers
1598 regarding lack of coverage of new-style classes have also been
1599 removed, since the coverage is now fairly reasonable.

1603================================
1604
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001605*Release date: 17-Jul-2008*
1606
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001607Core and Builtins
1608-----------------
1609
Georg Brandl3e483f62008-07-16 22:57:41 +00001610- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1611 its methods now allow for items objects that can be converted to
1612 an integer using operator.index().
1613
Mark Dickinson64b7e502008-07-16 09:40:03 +00001614- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1615 produced a ValueError instead of giving the correct float.
1616
Eric Smitha5fa5a22008-07-16 00:11:49 +00001617- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1618 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1619
Mark Dickinson7103aa42008-07-15 19:08:33 +00001620- Issue #3008: the float type has a new instance method 'float.hex'
1621 and a new class method 'float.fromhex' to convert floating-point
1622 numbers to and from hexadecimal strings, respectively.
1623
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001624- Issue #2235: __hash__ is once again inherited by default. To allow
1625 collections.Hashable to remain meaningful in the presence of the
1626 default hash implementation (object.__hash__), it is now possible
1627 to explicit block inheritance of hash by setting __hash__=None at
1628 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1629 level.
1630
Nick Coghlanb028f502008-07-13 14:52:36 +00001631- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1632 the parent module cannot be found while performing an absolute import.
1633 This means that an incorrectly defined __package__ attribute will
1634 now only prevent relative imports in that module rather than causing
1635 all imports from that module to fail.
1636
Nick Coghlan14ff9942008-07-08 14:21:42 +00001637- Issue #2517: Allow unicode messages in Exceptions again by correctly
1638 bypassing the instance dictionary when looking up __unicode__ on
1639 new-style classes.
1640
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001641- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1642 set to a custom object whose write() method happens to install
1643 another file in sys.stdout.
1644
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001645- Issue #3088: Corrected a race condition in classes derived from
1646 threading.local: the first member set by a thread could be saved in
1647 another thread's dictionary.
1648
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001649- Issue #3004: Minor change to slice.indices(): the start and stop
1650 arguments are now treated identically, making the behaviour easier
1651 to describe and understand. For example, slice(None, -10,
1652 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1653 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1654 10, -1).
1655
Georg Brandl278fc502008-07-19 12:46:12 +00001656- Issue #3219: Calling a function with repeated keyword arguments,
1657 f(a=2, a=23), would not cause a syntax error. This was a regression
1658 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001659
Georg Brandl278fc502008-07-19 12:46:12 +00001660- Issue #2862: Make int and float freelist management consistent with
1661 other freelists. Changes their CompactFreeList apis into
1662 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001663

1665-------
1666
Thomas Heller57adf222008-08-14 19:10:48 +00001667- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1668 api functions without holding the GIL, which could lead to a fatal
1669 error when they failed.
1670
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001671- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001679- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1680 ForkingPickler.register() to resolve conflict with ctypes.
1681
Vinay Sajip51e65192008-07-18 09:01:10 +00001682- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001683
Thomas Heller880f5292008-07-15 19:39:38 +00001684- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1685 a valid dlerror() message.
1686
Thomas Heller2bad6572008-07-15 17:19:50 +00001687- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1688 incomplete structure was created.
1689
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001690- Issue #3339: dummy_thread.acquire() should not return None.
1691
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001692- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1693
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001694- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001695
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001696- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1697 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001698 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001699 content-length. The problem had been corrected in the 2.4 branch, but never
1700 merged into trunk.
1701
Georg Brandle78fbcc2008-07-05 10:13:36 +00001702- Issue #2663: add filtering capability to shutil.copytree().

1706- Issue #1526: Allow more than 64k files to be added to Zip64 file.
1707
1708- Issue #1746: Correct handling of zipfile archive comments (previously
1709 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001710 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001711
Vinay Sajip51e65192008-07-18 09:01:10 +00001712- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001713 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001714
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001715- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1716 handling is now the same as that of other special attributes like __name__).
1717
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001718- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00002108 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002109
2110 This is controlled by the configure argument ``--with-universal-archs``:
2111
2112 - ``--with-universal-archs=all``: install 4-way universal
2113
2114 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2115
2116 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2117
2118 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Issue #1631171: Re-implement the 'warnings' module in C (the
2171 original Python code has been kept as backup). This will allow for
2172 using the 'warning's machinery in such places as the parser where
2173 use of pure Python code is not possible. Both the ``showarning()``
2174 and ``formatwarning()`` gain an optional 'line' argument which is
2175 not called by default for backwards-compatibility reasons. Setting
2176 ``warnings.showwarning()`` to an implementation that lacks support
2177 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002240- Issue #2550: The approach used by client/server code for obtaining
2241 ports to listen on in network-oriented tests has been refined in an
2242 effort to facilitate running multiple instances of the entire
2243 regression test suite in parallel without issue.
2244 test_support.bind_port() has been fixed such that it will always
2245 return a unique port -- which wasn't always the case with the
2246 previous implementation, especially if socket options had been set
2247 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2248 new implementation of bind_port() will actually raise an exception
2249 if it is passed an AF_INET/SOCK_STREAM socket with either the
2250 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2251 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2252 the socket it's been passed. This currently only applies to
2253 Windows. This option prevents any other sockets from binding to the
2254 host/port we've bound to, thus removing the possibility of the
2255 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2256 when a second SOCK_STREAM socket binds and accepts to a host/port
2257 that's already been bound by another socket. The optional preferred
2258 port parameter to bind_port() has been removed. Under no
2259 circumstances should tests be hard coding ports!
2260
2261 test_support.find_unused_port() has also been introduced, which will
2262 pass a temporary socket object to bind_port() in order to obtain an
2263 unused port. The temporary socket object is then closed and
2264 deleted, and the port is returned. This method should only be used
2265 for obtaining an unused port in order to pass to an external program
2266 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2267 a parameter to a server-oriented class that doesn't give you direct
2268 access to the underlying socket used.
2269
2270 Finally, test_support.HOST has been introduced, which should be used
2271 for the host argument of any relevant socket calls (i.e. bind and
2272 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002273
2274 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002276 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2277 test_asynchat and test_socket_ssl.
2278
Georg Brandl3ee81df2008-05-17 18:14:43 +00002279 It is now possible for multiple instances of the regression test
2280 suite to run in parallel without issue.

2546Core and builtins
2547-----------------
2548
Fred Drakea8ee94b2008-03-01 02:45:07 +00002549- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002550 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002551
Georg Brandlad61bc82008-02-23 15:11:18 +00002552- Issue #2067: file.__exit__() now calls subclasses' close() method.
2553
2554- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002555
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002556- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002557 issue 215555 for a discussion.
2558
Eric Smitha73fbe72008-02-23 03:09:44 +00002559- Added the future_builtins module, which contains hex() and oct().
2560 These are the PEP 3127 version of these functions, designed to be
2561 compatible with the hex() and oct() builtins from Python 3.0. They
2562 differ slightly in their output formats from the existing, unchanged
2563 Python 2.6 builtins. The expected usage of the future_builtins
2564 module is:
2565 from future_builtins import hex, oct
2566
Eric Smith7ef40bf2008-02-20 23:34:22 +00002567- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2568 exponents for exponents with absolute value < 100. Follows C99
2569 standard. This is a change on Windows, which would use 3 digits.
2570 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2571 so that any alterations it does to the resulting string will be
2572 available in stringlib/formatter.h (for float.__format__).
2573
Eric Smith5a3c1352008-02-19 13:21:56 +00002574- Implemented PEP 3101, Advanced String Formatting. This adds a new
2575 builtin format(); a format() method for str and unicode; a
2576 __format__() method to object, str, unicode, int, long, float, and
2577 datetime; the class string.Formatter; and the C API
2578 PyObject_Format().
2579
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580- Fixed several potential crashes, all caused by specially crafted
2581 __del__ methods exploiting objects in temporarily inconsistent
2582 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002583
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002584- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002585 prevent a possible crash: an Abstract Base Class would try to access
2586 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002587
Georg Brandl3ee81df2008-05-17 18:14:43 +00002588- Fixed repr() and str() of complex numbers with infinity or nan as
2589 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002590
Georg Brandl3ee81df2008-05-17 18:14:43 +00002591- Clear all free lists during a gc.collect() of the highest generation
2592 in order to allow pymalloc to free more arenas. Python may give back
2593 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002594
Georg Brandl3ee81df2008-05-17 18:14:43 +00002595- Issue #2045: Fix an infinite recursion triggered when printing a
2596 subclass of collections.defaultdict, if its default_factory is set
2597 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002598
Christian Heimesf75dbef2008-02-08 00:11:31 +00002599- Fixed a minor memory leak in dictobject.c. The content of the free
2600 list was not freed on interpreter shutdown.
2601
Georg Brandl3ee81df2008-05-17 18:14:43 +00002602- Limit free list of method and builtin function objects to 256
2603 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002604
Georg Brandl3ee81df2008-05-17 18:14:43 +00002605- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2606 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002607 to compact the internal free lists of pre-allocted ints and floats.
2608
Georg Brandl3ee81df2008-05-17 18:14:43 +00002609- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2610 calls. Python expected the return type int but the fork familie
2611 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002612
Georg Brandl3ee81df2008-05-17 18:14:43 +00002613- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2614 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002615
Georg Brandl3ee81df2008-05-17 18:14:43 +00002616- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2617 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002618
Georg Brandl3ee81df2008-05-17 18:14:43 +00002619- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2620 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002621
Georg Brandl3ee81df2008-05-17 18:14:43 +00002622- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2623 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002624
Georg Brandl3ee81df2008-05-17 18:14:43 +00002625- Patch #1473257: generator objects gain a gi_code attribute. This is
2626 the same object as the func_code attribute of the function that
2627 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002628
Georg Brandl3ee81df2008-05-17 18:14:43 +00002629- Issue #1920: "while 0" statements were completely removed by the
2630 compiler, even in the presence of an "else" clause, which is
2631 supposed to be run when the condition is false. Now the compiler
2632 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002633
Guido van Rossumeead05f2008-01-24 18:21:02 +00002634- A few crashers fixed: weakref_in_del.py (issue #1377858);
2635 loosing_dict_ref.py (issue #1303614, test67.py);
2636 borrowed_ref_[34].py (not in tracker).
2637
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002638- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002639 suppressed while an extension is loaded by calling SetErrorMode in
2640 dynload_win.c. The error is still reported properly.
2641
Georg Brandl3ee81df2008-05-17 18:14:43 +00002642- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002643 several extension methods and modules do not work without unicode
2644 support.
2645
Georg Brandl26543b12008-01-21 18:36:51 +00002646- Issue #1882: when compiling code from a string, encoding cookies in the
2647 second line of code were not always recognized correctly.
2648
Georg Brandl14404b62008-01-19 19:27:05 +00002649- Issue #1679: "0x" was taken as a valid integer literal.
2650
Georg Brandl6caad7d2008-01-26 14:19:22 +00002651- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002652 added.
2653
Christian Heimesc94e2b52008-01-14 04:13:37 +00002654- sys.float_info / PyFloat_GetInfo: The floating point information
2655 object was converted from a dict to a specialized structseq object.
2656
Georg Brandl3ee81df2008-05-17 18:14:43 +00002657- Patch #1816: Added sys.flags structseq. It exposes the status of
2658 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002659
Georg Brandl3ee81df2008-05-17 18:14:43 +00002660- Objects/structseq.c: Implemented new structseq representation. The
2661 patch makes structseqs (e.g. the return value of os.stat) more
2662 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002663
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664- Patch #1700288: added a type attribute cache that caches method
2665 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002666
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002667- Bug #1776: __import__() no longer accepts filenames on any platform.
2668 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002669
Georg Brandlaed6c662008-01-07 17:25:53 +00002670- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2671
Georg Brandl3ee81df2008-05-17 18:14:43 +00002672- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2673 envvar and sys.dont_write_bytecode attribute. All these can be set
2674 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002675
Georg Brandl3ee81df2008-05-17 18:14:43 +00002676- Improve some exception messages when Windows fails to load an
2677 extension module. Now we get for example '%1 is not a valid Win32
2678 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002679
Georg Brandl3ee81df2008-05-17 18:14:43 +00002680- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00002681
Georg Brandl3ee81df2008-05-17 18:14:43 +00002682- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2683 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002684
Christian Heimes0a8143f2007-12-18 23:22:54 +00002685- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686 and INF. float("nan"), float("inf") and float("-inf") now work on
2687 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002688
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Compiler now generates simpler and faster code for dictionary
2690 literals. The oparg for BUILD_MAP now indicates an estimated
2691 dictionary size. There is a new opcode, STORE_MAP, for adding
2692 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002693
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694- Issue #1638: %zd configure test fails on Linux.

2707 __package__ attribute.
2708
Georg Brandl3ee81df2008-05-17 18:14:43 +00002709- Issue #1402: Fix a crash on exit, when another thread is still
2710 running, and if the deallocation of its frames somehow calls the
2711 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002712

2722 file can now be directly executed by passing their name to the
2723 interpreter. The directory/zipfile is automatically inserted as the
2724 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002725
Georg Brandl3ee81df2008-05-17 18:14:43 +00002726- Issue #1265: Fix a problem with sys.settrace, if the tracing
2727 function uses a generator expression when at the same time the
2728 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002729
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002730- sets and frozensets now have an isdisjoint() method.
2731
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002732- optimize the performance of builtin.sum().
2733
Neal Norwitz44f326e2007-10-05 05:29:17 +00002734- Fix warnings found by the new version of the Coverity checker.
2735
Georg Brandl3ee81df2008-05-17 18:14:43 +00002736- The enumerate() builtin function is no longer bounded to sequences
2737 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2738 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002739
Georg Brandl3ee81df2008-05-17 18:14:43 +00002740- Issue #1686386: Tuple's tp_repr did not take into account the
2741 possibility of having a self-referential tuple, which is possible
2742 from C code. Nor did object's tp_str consider that a type's tp_str
2743 could do something that could lead to an inifinite recursion.
2744 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2745 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002746
Georg Brandl3ee81df2008-05-17 18:14:43 +00002747- Issue #1164: It was possible to trigger deadlock when using the
2748 'print' statement to write to a file since the GIL was not released
2749 as needed. Now PyObject_Print() does the right thing along with
2750 various tp_print implementations of the built-in types and those in
2751 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002752
Georg Brandl3ee81df2008-05-17 18:14:43 +00002753- Issue #1147: Exceptions were directly allowing string exceptions in
2754 their throw() method even though string exceptions no longer
2755 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002756
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002760- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002761 PyObject_Call() never calling back out to Python code to trigger
2762 recursion depth updates/checks. Required the creation of a static
2763 RuntimeError instance in case normalizing an exception put the
2764 recursion check value past its limit. Fixes crashers
2765 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002780- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002781 __*__ attributes. (Some already existed, e.g., __doc__ and
2782 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002783
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002784- Add -3 option to the interpreter to warn about features that are
2785 deprecated and will be changed/removed in Python 3.0.
2786

2788 calls.
2789
Collin Winter62903052007-05-18 23:11:24 +00002790- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791 "except E as target:". This is to provide forwards compatibility
2792 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002793
Brett Cannon229cee22007-05-05 01:34:02 +00002794- Deprecate BaseException.message as per PEP 352.
2795
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002797 inherited from a builtin base.
2798
Vinay Sajip8549ce32007-05-06 17:53:37 +00002799- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002800 setting a plain string, ie don't expand to single letter identifiers.
2801
Raymond Hettinger13936692007-04-11 18:40:58 +00002802- Request #1191699: Slices can now be pickled.
2803
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002804- Request #1193128: str.translate() now allows a None argument for
2805 translations that only remove characters without re-mapping the
2806 remaining characters.
2807
Georg Brandl5cb76c12007-03-21 09:00:39 +00002808- Patch #1682205: a TypeError while unpacking an iterable is no longer
2809 masked by a generic one with the message "unpack non-sequence".
2810
Neal Norwitzaa754b72007-03-21 06:39:48 +00002811- Remove unused file Python/fmod.c.
2812
Guido van Rossum143b5642007-03-23 04:58:42 +00002813- Bug #1683368: The object.__init__() and object.__new__() methods are
2814 now stricter in rejecting excess arguments. The only time when
2815 either allows excess arguments is when it is not overridden and the
2816 other one is. For backwards compatibility, when both are
2817 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002818 warning later). Also, type.__init__() insists on the same signature
2819 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002820
Georg Brandl3ee81df2008-05-17 18:14:43 +00002821- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2822 object to complex using its __complex__() method before falling back
2823 to the __float__() method. Therefore, the functions in the cmath
2824 module now can operate on objects that define a __complex__()
2825 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002826
Georg Brandl3ee81df2008-05-17 18:14:43 +00002827- Patch #1623563: allow __class__ assignment for classes with
2828 __slots__. The old and the new class are still required to have the
2829 same slot names.

2836 its type.

2842
Georg Brandl7b9c5552007-03-12 14:30:05 +00002843- Bug #1678647: write a newline after printing an exception in any
2844 case, even when converting the value to a string failed.
2845
Georg Brandl871f1bc2007-03-12 13:17:36 +00002846- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002847 its argument, if it exists. If not, it will work like before. This
2848 allows customizing the output of dir() in the presence of a
2849 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002850
Collin Winter276887b2007-03-12 16:11:39 +00002851- Patch #922167: Python no longer segfaults when faced with infinitely
2852 self-recursive reload() calls (as reported by bug #742342).
2853
Georg Brandl3ee81df2008-05-17 18:14:43 +00002854- Patch #1675981: remove unreachable code from ``type.__new__()``

2858 parthensized forms. This means complex(repr(x)) now works instead of
2859 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002860
Georg Brandlaa2321b2007-03-07 00:40:28 +00002861- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862 makes the filenames the warning module prints much more sensible
2863 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002864
Georg Brandl49aafc92007-03-07 00:34:46 +00002865- Variant of patch #697613: don't exit the interpreter on a SystemExit
2866 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867 variable is given, but break into the interactive interpreter just
2868 like on other exceptions or normal program exit.

2874 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002875
Georg Brandl0fca97a2007-03-05 22:28:08 +00002876- Patch #1674228: when assigning a slice (old-style), check for the
2877 sq_ass_slice instead of the sq_slice slot.
2878
Georg Brandl3ee81df2008-05-17 18:14:43 +00002879- When printing an unraisable error, don't print exceptions. before
2880 the name. This duplicates the behavior whening normally printing
2881 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002882
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00002889- Bug #1377858: Fix the segfaulting of the interpreter when an object
2890 created a weakref on itself during a __del__ call for new-style
2891 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003414 AttributeError instead of an IOError when the server's response
3415 didn't contain a valid HTTP status line.

3504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- unittest now verifies more of its assumptions. In particular,
3506 TestCase and TestSuite subclasses (not instances) are no longer
3507 accepted in TestSuite.addTest(). This should cause no
3508 incompatibility since it never made sense with ordinary subclasses

3789 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003790
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3792 with RFC 3207 and forgets any knowledge obtained from the server not
3793 obtained from the TLS negotiation itself. Patch contributed by Bill
3794 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003795
Georg Brandl3ee81df2008-05-17 18:14:43 +00003796- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003797 that the SMTP.starttls() caller no longer needs to call ehlo()
3798 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003799 does not claim to support starttls. Adds the
3800 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3881 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3882 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003899 time so that opening a database previously created with the DB_DUP
3900 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3901 opens. Specifically: dictionary assignment to a DB object will
3902 replace all values for a given key when the database allows
3903 duplicate values. DB users should use DB.put(k, v) when they want
3904 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003905

3911 characters with ASCII value less than 32. Also, it correctly quotes
3912 dots only if they occur on a single line, as opposed to the previous
3913 behavior of quoting dots if they are the second character of any
3914 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003915

Georg Brandl3ee81df2008-05-17 18:14:43 +00004250- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4251 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4252 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004253
4254- Patch #1720595: add T_BOOL to the range of structmember types.
4255
4256- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and

4258
Georg Brandl3ee81df2008-05-17 18:14:43 +00004259- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4260 of w# format code incorrectly truncated the length to an int, even
4261 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4262 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004263
Georg Brandl3ee81df2008-05-17 18:14:43 +00004264- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4265 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004267- PEP 3123: Provide forward compatibility with Python 3.0, while
4268 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4269 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004271- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4272 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004273
4274- Patch #1733960: Allow T_LONGLONG to accept ints.
4275
4276- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4277
Christian Heimes000a0742008-01-03 22:16:32 +00004278- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00004280- Bug #1637022: Prefix AST symbols with _Py_.
4281
4282- Fix some leftovers from the conversion from int to Py_ssize_t
4283 (relevant to strings and sequences of more than 2**31 items).
4284
4285- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4286 outside of pystate.c and should not be necessary.
4287
Georg Brandl3ee81df2008-05-17 18:14:43 +00004288- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4289 absolute imports. In earlier versions they might have used relative
4290 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004291
Georg Brandl3ee81df2008-05-17 18:14:43 +00004292- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4293 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004294
Georg Brandl3ee81df2008-05-17 18:14:43 +00004295- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004302- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4303 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4304 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4305 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004306
Georg Brandl3ee81df2008-05-17 18:14:43 +00004307- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Removed the macfs module. It had been deprecated since Python 2.5.
4321 This lead to the deprecation of macostools.touched() as it relied
4322 solely on macfs and was a no-op under OS X.
