11
12Core and Builtins
13-----------------
14
Benjamin Peterson4afbba32009-06-13 01:40:00 +000015- In the slice AST type, the step field will always be None if a step expression
16 is not specified.
17
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +000018- Issue #4547: When debugging a very large function, it was not always
19 possible to update the lineno attribute of the current frame.
20
Antoine Pitrou46dbe272009-05-30 21:27:00 +000021- Issue #5330: C functions called with keyword arguments were not reported by
22 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
23
Raymond Hettinger578a2282009-05-29 04:58:52 +000024- Issue #5982: staticmethod and classmethod now expose the wrapped
25 function with __func__.
26
Raymond Hettinger822b87f2009-05-29 01:46:48 +000027- Added support for multiple context managers in the same with-statement.
28 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +000029
Benjamin Peterson1880d8b2009-05-25 13:13:44 +000030- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
31 statement and correctly lookup the __enter__ and __exit__ special methods.
32
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000033- Issue #5829: complex("1e500") no longer raises OverflowError. This
34 makes it consistent with float("1e500") and interpretation of real
35 and imaginary literals.
36
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +000037- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
38
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +000039- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
40 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +000041
R. David Murray525cffc2009-05-13 13:07:14 +000042- Issue #5994: the marshal module now has docstrings.
43
Mark Dickinsonb1d45852009-05-11 15:33:08 +000044- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
45 (1) inf and nan strings with trailing whitespace were incorrectly
46 rejected; (2) parsing of strings representing infinities and nans
47 was locale aware; and (3) the interpretation of fromhex('-nan')
48 didn't match that of float('-nan').
49
Eric Smitha985a3a2009-05-05 18:26:08 +000050- Issue #5920: For float.__format__, change the behavior with the
51 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
52 to be like 'g' but with at least one decimal point and with a
53 default precision of 12. Previously, the behavior the same but with
54 a default precision of 6. This more closely matches str(), and
55 reduces surprises when adding alignment flags to the empty
56 presentation type. This also affects the new complex.__format__ in
57 the same way.
58
R. David Murray7ba8e1c2009-05-04 22:16:24 +000059- Issue #5890: in subclasses of 'property' the __doc__ attribute was
60 shadowed by classtype's, even if it was None. property now
61 inserts the __doc__ into the subclass instance __dict__.
62
Antoine Pitrou653dece2009-05-04 18:32:32 +000063- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
64 sequences. Patch by Nick Barnes and Victor Stinner.
65
Vinay Sajipf9b01fe2009-05-09 12:07:17 +000066- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +000067 format(complex(1, 2./3), '.5') now produces a sensible result.
68
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000069- Issue #5864: Fix empty format code formatting for floats so that it
70 never gives more than the requested number of significant digits.
71
Eric Smithcac7af62009-04-27 19:04:37 +000072- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
73 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
74
Martin v. Löwis99f27792009-04-26 00:53:18 +000075- Issue #4971: Fix titlecase for characters that are their own
76 titlecase, but not their own uppercase.
77
Eric Smith068f0652009-04-25 21:40:15 +000078- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
79 _PyOS_double_to_string or PyOS_double_to_string.
80
Benjamin Peterson5083dc52009-04-25 00:41:22 +000081- Issue #5283: Setting __class__ in __del__ caused a segfault.
82
Mark Dickinson95bc9802009-04-24 12:46:53 +000083- Issue #5816: complex(repr(z)) now recovers z exactly, even when
84 z involves nans, infs or negative zeros.
85
Eric Smithaca19e62009-04-22 13:29:05 +000086- Implement PEP 378, Format Specifier for Thousands Separator, for
87 floats, ints, and longs.
88
89- Issue #5515: 'n' formatting for ints, longs, and floats handles
90 leading zero formatting poorly.
91
92- Issue #5772: For float.__format__, don't add a trailing ".0" if
93 we're using no type code and we have an exponent.
94
Mark Dickinson6736cf82009-04-20 21:13:33 +000095- Issue #3166: Make long -> float (and int -> float) conversions
96 correctly rounded.
97
Benjamin Petersond4d400c2009-04-18 20:12:47 +000098- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
99 some builtin types.
100
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000101- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000102 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000103
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000104- Issue #5759: float() didn't call __float__ on str subclasses.
105
Georg Brandl3c4a5462009-04-12 12:08:12 +0000106- Issue #5704: the "-3" command-line option now implies "-t".
107
R. David Murray0374a822009-04-09 21:54:50 +0000108- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
109 its clarity and its speed.
110
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000111- Issue #2396: the memoryview object was backported from Python 3.1.

117
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000118- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
119 the end sys.path, for compatibility with the system install of Python.
120
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000121- Issue #4688: Add a heuristic so that tuples and dicts containing only
122 untrackable objects are not tracked by the garbage collector. This can
123 reduce the size of collections and therefore the garbage collection overhead
124 on long-running programs, depending on their particular use of datatypes.
125
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000126- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
127 improve its performance. Long divisions and remainder operations
128 are now between 50% and 150% faster.
129
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000130- Issue #4258: Make it possible to use base 2**30 instead of base
131 2**15 for the internal representation of integers, for performance
132 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
133 --enable-big-digits option to configure, which overrides the
134 default. Add sys.long_info structseq to provide information about
135 the internal format.
136
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000137- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
138 result traceback.__members__ no longer exists.)
139
Mark Dickinson6b265f12009-03-18 16:07:26 +0000140- Issue #4474: PyUnicode_FromWideChar now converts characters outside
141 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
142 and sizeof(Py_UNICODE) == 2.
143
Eric Smith6f42edb2009-03-14 11:57:26 +0000144- Issue #5237: Allow auto-numbered fields in str.format(). For
145 example: '{} {}'.format(1, 2) == '1 2'.
146
Brett Cannon6c4cff02009-03-11 04:51:06 +0000147- Issue #3652: Make the 'line' argument for warnings.showwarning() a
148 requirement. Means the DeprecationWarning from Python 2.6 can go away.
149
Eric Smithe9fb6862009-02-20 14:02:36 +0000150- Issue #5247: Improve error message when unknown format codes are
151 used when using str.format() with str, unicode, long, int, and
152 float arguments.
153
Raymond Hettinger08259e82009-02-18 23:10:19 +0000154- Running Python with the -3 option now also warns about classic division
155 for ints and longs.
156
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000157- Issue #5260: Long integers now consume less memory: average
158 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
159 on a 64-bit system.
160
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000161- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
162 rotating the object pointer by 4 bits to the right.
163
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000164- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
165 it now forces its argument to double before testing for infinity.
166
Benjamin Petersone18ef192009-01-20 14:21:16 +0000167- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
168
Georg Brandl29c6a282009-04-05 20:23:13 +0000169- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000170 were suppressing all exceptions. These include list(), filter(), map(),
171 zip(), and bytearray().
172
Benjamin Peterson596d3062009-01-19 15:42:23 +0000173- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
174 functions.
175
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000176- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

180
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000181- Issue #4935: The overflow checking code in the expandtabs() method common
182 to str, bytes and bytearray could be optimized away by the compiler, letting
183 the interpreter segfault instead of raising an error.
184
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000185- Issue #3720: Fix a crash when an iterator modifies its class and removes its
186 __next__ method.

191
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000192- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
193 collecting the oldest generation) so that allocating lots of objects without
194 destroying them does not show quadratic performance. Based on a proposal by
195 Martin von Löwis at
196 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
197
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000198- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
199
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000200- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
201 an existing .py counterpart, override the co_filename attributes of all
202 code objects if the original filename is obsolete (which can happen if the
203 file has been renamed, moved, or if it is accessed through different paths).
204 Patch by Ziga Seilnacht and Jean-Paul Calderone.
205
Martin v. Löwis5344c992009-01-02 20:32:55 +0000206- Issue #4075: Use OutputDebugStringW in Py_FatalError.

213
Nick Coghlan180e4002008-12-30 01:18:48 +0000214- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
215 where the tp_hash and tp_dict slots are both NULL.
216
Benjamin Peterson7af65562008-12-29 17:56:58 +0000217- Issue #4764: With io.open, IOError.filename is set when trying to open a
218 directory on POSIX systems.
219
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000220- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

227 fail.
228
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000229- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
230 print elapsed times, not only when some objects are uncollectable /
231 unreachable. Original patch by Neil Schemenauer.
232
Mark Dickinson1a707982008-12-17 16:14:37 +0000233- Issue #3439: Add a bit_length method to int and long.

239 context manager returns a value that cannot be converted to a bool.
240
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000241- Issue #4597: Fixed several opcodes that weren't always propagating
242 exceptions.
243
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000244- Issue #4445: Replace "sizeof(PyStringObject)" with
245 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
246 str instances. On a typical machine this saves 3 bytes of memory
247 (on average) per string allocation.
248
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000249- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
250 interpreter to abort ("Fatal Python error: Could not reset the stack!")
251 instead of throwing a MemoryError.
252
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000253- Issue #3689: The list reversed iterator now supports __length_hint__

257 module couldn't be imported and \N escapes were present.
258
Vinay Sajip213faca2008-12-03 23:22:58 +0000259- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000260 method on file objects with closefd=False. The file descriptor is still
261 kept open but the file object behaves like a closed file. The ``FileIO``
262 object also got a new readonly attribute ``closefd``.
263
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000264- Issue #4348: Some bytearray methods returned that didn't cause any change to
265 the bytearray, returned the same bytearray instead of a copy.
266
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000267- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
268

270
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000271- Issue #4048: The parser module now correctly validates relative imports.
272
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000273- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
274 exec statement.
275
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000276- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
277 method does not return iterators for the 4th and 5th items.
278
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000279- Issue #4209: Enabling unicode_literals and the print_function in the same
280 __future__ import didn't work.
281
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000282- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000283 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000284
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000285- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
286 returned a path longer than MAX_PATH. (But It's doubtful this code path is
287 really executed because I cannot move to such directory on win2k)
288
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000289- Issue #4069: When set.remove(element) is used with a set element, the element
290 is temporarily replaced with an equivalent frozenset. But the eventual
291 KeyError would always report the empty frozenset([]) as the missing key. Now
292 it correctly refers to the initial element.
293
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000294- Issue #4509: Various issues surrounding resize of bytearray objects to
295 which there are buffer exports.

1138 test_heapq and test_warnings have been adjusted to use it, tests for
1139 other modules with both C and Python implementations in the stdlib
1140 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00001148- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001149 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001150 from test support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001244- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1245
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001246- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1247 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1248 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1249 ``printf`` function, whereas PyString_FromFormat has an independent
1250 implementation and uses "%zd" on all platforms for size_t values.
1251 This makes a difference on win64, where ``printf`` needs "%Id" to display
1252 64bit values.
1253
Benjamin Peterson97179b02008-09-09 20:55:01 +00001254- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1258 object; previously an int would be returned for small values. the __long__
1259 method is allowed to return either an int or a long, but the behaviour of
1260 float objects should not change to respect backward compatibility.
1261
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001262- Issue #3751: str.rpartition would perform a left-partition when called with
1263 a unicode argument.
1264
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001265- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001268 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001269 was correctly parsed but parsing of subsequent arguments failed.
1270
Vinay Sajip35e3b032008-09-01 14:33:59 +00001271- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001272 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1273 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1274 when given a tuple of classes as second argument, were looking up
1275 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1276 type object.
1277
Neal Norwitz18aa3882008-08-24 05:04:52 +00001278- Fix crashes on memory allocation failure found with failmalloc.
1279
1280- Fix memory leaks found with valgrind and update suppressions file.
1281
1282- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1283
1284- Fix problem using wrong name in decimal module reported by pychecker.

1347 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1348 for catch_warnings() also led to an improvement in the raising of a

1421-----------------
1422
Guido van Rossumf8402962008-08-20 15:01:50 +00001423- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1424 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1425 extensions do not automatically benefit from the class attribute
1426 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1427 to their tp_flags field if they care. This is a backwards
1428 compatibility feature; in 3.0, all types will use the cache by
1429 default.
1430
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001431- Keyword arguments can now follow starred arguments. (``f(a, *args,
1432 keyword=23)`` is now valid syntax.)
1433
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001434- ctypes function pointers that are COM methods have a boolean True

Georg Brandl1e13ea92008-08-11 09:07:59 +00001441- Issue #3537: Fix an assertion failure when an empty but presized dict
1442 object was stored in the freelist.
1443
Mark Dickinsonb6467572008-08-04 21:30:09 +00001444- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1445 ValueError consistently across platforms.
1446
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001447- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1448 (64bit Unix, for example), unichr() would truncate its argument and return
1449 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1450
Neal Norwitze7d8be82008-07-31 17:17:14 +00001451- Apply security patches from Apple.
1452
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001453- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1454 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1455
Antoine Pitrou92f82162008-07-25 22:22:08 +00001456- Issue #1819: function calls with several named parameters are now on
1457 average 35% faster (as measured by pybench).
1458
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001459- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1460 the python debugger steps into a class statement: the free variables (local
1461 variables defined in an outer scope) would be deleted from the outer scope.
1462
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001463- Issue #2620: Overflow checking when allocating or reallocating memory
1464 was not always being done properly in some python types and extension
1465 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1466 all been updated to perform better checks and places in the code that
1467 would previously leak memory on the error path when such an allocation
1468 failed have been fixed.

1477
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001478- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1479 version reported by these tools does not necessarily follow the python
1480 version numbering scheme, so the module is less strict when parsing it.
1481
Nick Coghlanf70385a2008-08-18 12:42:46 +00001482- Issue #2235: Added Py3k warnings for types which will become unhashable
1483 under the stricter __hash__ inheritance rules in 3.0. Several types
1484 which did not meet the rules for hash invariants and were already
1485 unhashable in 3.0 have now been explicitly flagged as unhashable in
1486 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1487 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1488
Brett Cannon88f801d2008-08-18 00:46:22 +00001489- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1512
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001513- Issue #2676: in the email package, content-type parsing was hanging on

1515 regular expression.
1516
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001517- Issue #3476: binary buffered reading through the new "io" library is now
1518 thread-safe.
1519
Brett Cannonbf3157b2008-08-14 05:00:03 +00001520- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1521 since mimetools itself is deprecated. Because modules are cached, all
1522 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1523
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001524- Issue #3134: shutil referenced undefined WindowsError symbol.

1530 version that did not raise a DeprecationWarning under -3.
1531
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001532- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1533 a MemoryError rather than silently stop the iteration.
1534
Guido van Rossum59ce9012008-08-09 14:55:34 +00001535- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1536 to _sre.compile() will now be rejected. This should not affect anybody
1537 since the re.compile() function never generates invalid re-bytecode.

Skip Montanaroa032bf42008-08-08 22:52:51 +00001539- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1540 upon first access it can be automatically initialized from the csv file if
1541 it wasn't initialized during instantiation.
1542
Brett Cannon3aa2a492008-08-06 22:28:09 +00001543- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1544 the reload() built-in has been removed.
1545
Brett Cannon7e30b672008-08-04 21:52:25 +00001546- Changed code in the following modules/packages to remove warnings raised

1555 raised an AttributeError.
1556
Benjamin Peterson01a24322008-07-28 23:35:27 +00001557- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001558 asking for a specific length. This problem only affected files opened
1559 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001560

1583
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001584- Issue #3394: zipfile.writestr sets external attributes when passed a
1585 file name rather than a ZipInfo instance, so files are extracted with
1586 mode 0600 rather than 000 under Unix.
1587
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001588- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1589 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001600- Issue #2235: the C API function PyObject_HashNotImplemented and its
1601 interaction with the tp_hash slot (added in 2.6b2) are now documented
1602
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001603- Issue #643841: The language reference now provides more detailed
1604 coverage of the lookup process for special methods. The disclaimers
1605 regarding lack of coverage of new-style classes have also been
1606 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001614Core and Builtins
1615-----------------
1616
Georg Brandl3e483f62008-07-16 22:57:41 +00001617- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1618 its methods now allow for items objects that can be converted to
1619 an integer using operator.index().
1620
Mark Dickinson64b7e502008-07-16 09:40:03 +00001621- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1622 produced a ValueError instead of giving the correct float.
1623
Eric Smitha5fa5a22008-07-16 00:11:49 +00001624- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1625 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1626
Mark Dickinson7103aa42008-07-15 19:08:33 +00001627- Issue #3008: the float type has a new instance method 'float.hex'
1628 and a new class method 'float.fromhex' to convert floating-point
1629 numbers to and from hexadecimal strings, respectively.
1630
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001631- Issue #2235: __hash__ is once again inherited by default. To allow
1632 collections.Hashable to remain meaningful in the presence of the
1633 default hash implementation (object.__hash__), it is now possible
1634 to explicit block inheritance of hash by setting __hash__=None at
1635 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1636 level.
1637
Nick Coghlanb028f502008-07-13 14:52:36 +00001638- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1639 the parent module cannot be found while performing an absolute import.
1640 This means that an incorrectly defined __package__ attribute will
1641 now only prevent relative imports in that module rather than causing
1642 all imports from that module to fail.
1643
Nick Coghlan14ff9942008-07-08 14:21:42 +00001644- Issue #2517: Allow unicode messages in Exceptions again by correctly
1645 bypassing the instance dictionary when looking up __unicode__ on
1646 new-style classes.
1647
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001648- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1649 set to a custom object whose write() method happens to install
1650 another file in sys.stdout.
1651
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001652- Issue #3088: Corrected a race condition in classes derived from
1653 threading.local: the first member set by a thread could be saved in
1654 another thread's dictionary.
1655
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001656- Issue #3004: Minor change to slice.indices(): the start and stop
1657 arguments are now treated identically, making the behaviour easier
1658 to describe and understand. For example, slice(None, -10,
1659 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1660 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1661 10, -1).
1662
Georg Brandl278fc502008-07-19 12:46:12 +00001663- Issue #3219: Calling a function with repeated keyword arguments,
1664 f(a=2, a=23), would not cause a syntax error. This was a regression
1665 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001666
Georg Brandl278fc502008-07-19 12:46:12 +00001667- Issue #2862: Make int and float freelist management consistent with
1668 other freelists. Changes their CompactFreeList apis into
1669 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001670

1672-------
1673
Thomas Heller57adf222008-08-14 19:10:48 +00001674- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1675 api functions without holding the GIL, which could lead to a fatal
1676 error when they failed.
1677
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001678- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1687 ForkingPickler.register() to resolve conflict with ctypes.
1688
Vinay Sajip51e65192008-07-18 09:01:10 +00001689- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00001691- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1692 a valid dlerror() message.
1693
Thomas Heller2bad6572008-07-15 17:19:50 +00001694- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1695 incomplete structure was created.
1696
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001697- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00001699- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1700
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001701- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001702
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001703- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1704 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001705 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001706 content-length. The problem had been corrected in the 2.4 branch, but never
1707 merged into trunk.
1708
Georg Brandle78fbcc2008-07-05 10:13:36 +00001709- Issue #2663: add filtering capability to shutil.copytree().

1715- Issue #1746: Correct handling of zipfile archive comments (previously
1716 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001717 Zip files with archives by setting the 'comment' attribute of a ZipFile.

2114 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002115 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002116
2117 This is controlled by the configure argument ``--with-universal-archs``:
2118
2119 - ``--with-universal-archs=all``: install 4-way universal
2120
2121 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2122
2123 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2124
2125 This option should be used in combination with ``--enable-universalsdk=``.
2126
2127 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002177- Issue #1631171: Re-implement the 'warnings' module in C (the
2178 original Python code has been kept as backup). This will allow for
2179 using the 'warning's machinery in such places as the parser where
2180 use of pure Python code is not possible. Both the ``showarning()``
2181 and ``formatwarning()`` gain an optional 'line' argument which is
2182 not called by default for backwards-compatibility reasons. Setting
2183 ``warnings.showwarning()`` to an implementation that lacks support
2184 for the ``line`` argument will raise a DeprecationWarning.

2208
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002209- The getpass module has been improved on Unix. It now uses /dev/tty
2210 by default and uses stderr instead of stdout. A GetPassWarning is
2211 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002226- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002227 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002247- Issue #2550: The approach used by client/server code for obtaining
2248 ports to listen on in network-oriented tests has been refined in an
2249 effort to facilitate running multiple instances of the entire
2250 regression test suite in parallel without issue.
2251 test_support.bind_port() has been fixed such that it will always
2252 return a unique port -- which wasn't always the case with the
2253 previous implementation, especially if socket options had been set
2254 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2255 new implementation of bind_port() will actually raise an exception
2256 if it is passed an AF_INET/SOCK_STREAM socket with either the
2257 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2258 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2259 the socket it's been passed. This currently only applies to
2260 Windows. This option prevents any other sockets from binding to the
2261 host/port we've bound to, thus removing the possibility of the
2262 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2263 when a second SOCK_STREAM socket binds and accepts to a host/port
2264 that's already been bound by another socket. The optional preferred
2265 port parameter to bind_port() has been removed. Under no
2266 circumstances should tests be hard coding ports!
2267
2268 test_support.find_unused_port() has also been introduced, which will
2269 pass a temporary socket object to bind_port() in order to obtain an
2270 unused port. The temporary socket object is then closed and
2271 deleted, and the port is returned. This method should only be used
2272 for obtaining an unused port in order to pass to an external program
2273 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2274 a parameter to a server-oriented class that doesn't give you direct
2275 access to the underlying socket used.
2276
2277 Finally, test_support.HOST has been introduced, which should be used
2278 for the host argument of any relevant socket calls (i.e. bind and
2279 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002280

2553Core and builtins
2554-----------------
2555
Fred Drakea8ee94b2008-03-01 02:45:07 +00002556- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002557 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002558
Georg Brandlad61bc82008-02-23 15:11:18 +00002559- Issue #2067: file.__exit__() now calls subclasses' close() method.
2560
2561- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002562
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002563- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002564 issue 215555 for a discussion.
2565
Eric Smitha73fbe72008-02-23 03:09:44 +00002566- Added the future_builtins module, which contains hex() and oct().
2567 These are the PEP 3127 version of these functions, designed to be
2568 compatible with the hex() and oct() builtins from Python 3.0. They
2569 differ slightly in their output formats from the existing, unchanged
2570 Python 2.6 builtins. The expected usage of the future_builtins
2571 module is:
2572 from future_builtins import hex, oct
2573
Eric Smith7ef40bf2008-02-20 23:34:22 +00002574- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2575 exponents for exponents with absolute value < 100. Follows C99
2576 standard. This is a change on Windows, which would use 3 digits.
2577 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2578 so that any alterations it does to the resulting string will be
2579 available in stringlib/formatter.h (for float.__format__).
2580
Eric Smith5a3c1352008-02-19 13:21:56 +00002581- Implemented PEP 3101, Advanced String Formatting. This adds a new
2582 builtin format(); a format() method for str and unicode; a
2583 __format__() method to object, str, unicode, int, long, float, and
2584 datetime; the class string.Formatter; and the C API
2585 PyObject_Format().
2586
Georg Brandl3ee81df2008-05-17 18:14:43 +00002587- Fixed several potential crashes, all caused by specially crafted
2588 __del__ methods exploiting objects in temporarily inconsistent
2589 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002590
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002591- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002592 prevent a possible crash: an Abstract Base Class would try to access
2593 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002594
Georg Brandl3ee81df2008-05-17 18:14:43 +00002595- Fixed repr() and str() of complex numbers with infinity or nan as
2596 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002597
Georg Brandl3ee81df2008-05-17 18:14:43 +00002598- Clear all free lists during a gc.collect() of the highest generation
2599 in order to allow pymalloc to free more arenas. Python may give back
2600 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002601
Georg Brandl3ee81df2008-05-17 18:14:43 +00002602- Issue #2045: Fix an infinite recursion triggered when printing a
2603 subclass of collections.defaultdict, if its default_factory is set
2604 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002605
Christian Heimesf75dbef2008-02-08 00:11:31 +00002606- Fixed a minor memory leak in dictobject.c. The content of the free
2607 list was not freed on interpreter shutdown.
2608
Georg Brandl3ee81df2008-05-17 18:14:43 +00002609- Limit free list of method and builtin function objects to 256
2610 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002611
Georg Brandl3ee81df2008-05-17 18:14:43 +00002612- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2613 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002614 to compact the internal free lists of pre-allocted ints and floats.
2615
Georg Brandl3ee81df2008-05-17 18:14:43 +00002616- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2617 calls. Python expected the return type int but the fork familie
2618 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002619
Georg Brandl3ee81df2008-05-17 18:14:43 +00002620- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2621 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002622
Georg Brandl3ee81df2008-05-17 18:14:43 +00002623- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2624 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002625
Georg Brandl3ee81df2008-05-17 18:14:43 +00002626- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2627 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002628
Georg Brandl3ee81df2008-05-17 18:14:43 +00002629- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2630 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002631
Georg Brandl3ee81df2008-05-17 18:14:43 +00002632- Patch #1473257: generator objects gain a gi_code attribute. This is
2633 the same object as the func_code attribute of the function that
2634 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002635
Georg Brandl3ee81df2008-05-17 18:14:43 +00002636- Issue #1920: "while 0" statements were completely removed by the
2637 compiler, even in the presence of an "else" clause, which is
2638 supposed to be run when the condition is false. Now the compiler
2639 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002640
Guido van Rossumeead05f2008-01-24 18:21:02 +00002641- A few crashers fixed: weakref_in_del.py (issue #1377858);
2642 loosing_dict_ref.py (issue #1303614, test67.py);
2643 borrowed_ref_[34].py (not in tracker).
2644
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002645- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002646 suppressed while an extension is loaded by calling SetErrorMode in
2647 dynload_win.c. The error is still reported properly.
2648
Georg Brandl3ee81df2008-05-17 18:14:43 +00002649- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002650 several extension methods and modules do not work without unicode
2651 support.
2652
Georg Brandl26543b12008-01-21 18:36:51 +00002653- Issue #1882: when compiling code from a string, encoding cookies in the
2654 second line of code were not always recognized correctly.
2655
Georg Brandl14404b62008-01-19 19:27:05 +00002656- Issue #1679: "0x" was taken as a valid integer literal.
2657
Georg Brandl6caad7d2008-01-26 14:19:22 +00002658- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002659 added.
2660
Christian Heimesc94e2b52008-01-14 04:13:37 +00002661- sys.float_info / PyFloat_GetInfo: The floating point information
2662 object was converted from a dict to a specialized structseq object.
2663
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664- Patch #1816: Added sys.flags structseq. It exposes the status of
2665 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002666
Georg Brandl3ee81df2008-05-17 18:14:43 +00002667- Objects/structseq.c: Implemented new structseq representation. The
2668 patch makes structseqs (e.g. the return value of os.stat) more
2669 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002670
Georg Brandl3ee81df2008-05-17 18:14:43 +00002671- Patch #1700288: added a type attribute cache that caches method
2672 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002673
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002674- Bug #1776: __import__() no longer accepts filenames on any platform.
2675 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002676
Georg Brandlaed6c662008-01-07 17:25:53 +00002677- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2678
Georg Brandl3ee81df2008-05-17 18:14:43 +00002679- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2680 envvar and sys.dont_write_bytecode attribute. All these can be set
2681 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002682
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683- Improve some exception messages when Windows fails to load an
2684 extension module. Now we get for example '%1 is not a valid Win32
2685 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002686
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2690 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002691
Christian Heimes0a8143f2007-12-18 23:22:54 +00002692- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002693 and INF. float("nan"), float("inf") and float("-inf") now work on
2694 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002695
Georg Brandl3ee81df2008-05-17 18:14:43 +00002696- Compiler now generates simpler and faster code for dictionary
2697 literals. The oparg for BUILD_MAP now indicates an estimated
2698 dictionary size. There is a new opcode, STORE_MAP, for adding
2699 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002703- Issue #1620: New property decorator syntax was modifying the
2704 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002705
Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Issue #1538: Avoid copying string in split/rsplit if the split char
2707 is not found.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002709- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002710 SystemError.
2711
Nick Coghlanef01d822007-12-03 12:55:17 +00002712- PEP 366: Allow explicit relative imports when executing modules
2713 inside packages with the -m switch via a new module level
2714 __package__ attribute.
2715
Georg Brandl3ee81df2008-05-17 18:14:43 +00002716- Issue #1402: Fix a crash on exit, when another thread is still
2717 running, and if the deallocation of its frames somehow calls the
2718 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002719

2729 file can now be directly executed by passing their name to the
2730 interpreter. The directory/zipfile is automatically inserted as the
2731 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002732
Georg Brandl3ee81df2008-05-17 18:14:43 +00002733- Issue #1265: Fix a problem with sys.settrace, if the tracing
2734 function uses a generator expression when at the same time the
2735 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002736
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002737- sets and frozensets now have an isdisjoint() method.
2738
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002739- optimize the performance of builtin.sum().
2740
Neal Norwitz44f326e2007-10-05 05:29:17 +00002741- Fix warnings found by the new version of the Coverity checker.
2742
Georg Brandl3ee81df2008-05-17 18:14:43 +00002743- The enumerate() builtin function is no longer bounded to sequences
2744 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2745 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002746
Georg Brandl3ee81df2008-05-17 18:14:43 +00002747- Issue #1686386: Tuple's tp_repr did not take into account the
2748 possibility of having a self-referential tuple, which is possible
2749 from C code. Nor did object's tp_str consider that a type's tp_str
2750 could do something that could lead to an inifinite recursion.
2751 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2752 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002753
Georg Brandl3ee81df2008-05-17 18:14:43 +00002754- Issue #1164: It was possible to trigger deadlock when using the
2755 'print' statement to write to a file since the GIL was not released
2756 as needed. Now PyObject_Print() does the right thing along with
2757 various tp_print implementations of the built-in types and those in
2758 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Issue #1147: Exceptions were directly allowing string exceptions in
2761 their throw() method even though string exceptions no longer
2762 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002763
Georg Brandl3ee81df2008-05-17 18:14:43 +00002764- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002767- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002768 PyObject_Call() never calling back out to Python code to trigger
2769 recursion depth updates/checks. Required the creation of a static
2770 RuntimeError instance in case normalizing an exception put the
2771 recursion check value past its limit. Fixes crashers
2772 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002788 __*__ attributes. (Some already existed, e.g., __doc__ and
2789 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002790
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002791- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00002798 "except E as target:". This is to provide forwards compatibility
2799 with Python 3.0.

2819
Guido van Rossum143b5642007-03-23 04:58:42 +00002820- Bug #1683368: The object.__init__() and object.__new__() methods are
2821 now stricter in rejecting excess arguments. The only time when
2822 either allows excess arguments is when it is not overridden and the
2823 other one is. For backwards compatibility, when both are
2824 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002825 warning later). Also, type.__init__() insists on the same signature
2826 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002827
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2829 object to complex using its __complex__() method before falling back
2830 to the __float__() method. Therefore, the functions in the cmath
2831 module now can operate on objects that define a __complex__()
2832 method.

2849
Georg Brandl7b9c5552007-03-12 14:30:05 +00002850- Bug #1678647: write a newline after printing an exception in any
2851 case, even when converting the value to a string failed.
2852
Georg Brandl871f1bc2007-03-12 13:17:36 +00002853- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002854 its argument, if it exists. If not, it will work like before. This
2855 allows customizing the output of dir() in the presence of a
2856 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002857
Collin Winter276887b2007-03-12 16:11:39 +00002858- Patch #922167: Python no longer segfaults when faced with infinitely
2859 self-recursive reload() calls (as reported by bug #742342).

2866 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002867
Georg Brandlaa2321b2007-03-07 00:40:28 +00002868- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002869 makes the filenames the warning module prints much more sensible
2870 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002871

Georg Brandl0fca97a2007-03-05 22:28:08 +00002883- Patch #1674228: when assigning a slice (old-style), check for the
2884 sq_ass_slice instead of the sq_slice slot.
2885
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00003512- unittest now verifies more of its assumptions. In particular,
3513 TestCase and TestSuite subclasses (not instances) are no longer
3514 accepted in TestSuite.addTest(). This should cause no
3515 incompatibility since it never made sense with ordinary subclasses
3516 -- the failure just occurred later, with a more cumbersome
3517 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003798- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3799 with RFC 3207 and forgets any knowledge obtained from the server not
3800 obtained from the TLS negotiation itself. Patch contributed by Bill
3801 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003802
Georg Brandl3ee81df2008-05-17 18:14:43 +00003803- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003804 that the SMTP.starttls() caller no longer needs to call ehlo()
3805 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003806 does not claim to support starttls. Adds the
3807 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3888 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3889 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003906 time so that opening a database previously created with the DB_DUP
3907 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3908 opens. Specifically: dictionary assignment to a DB object will
3909 replace all values for a given key when the database allows
3910 duplicate values. DB users should use DB.put(k, v) when they want
3911 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003912

3918 characters with ASCII value less than 32. Also, it correctly quotes
3919 dots only if they occur on a single line, as opposed to the previous
3920 behavior of quoting dots if they are the second character of any
3921 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003922

Georg Brandl3ee81df2008-05-17 18:14:43 +00004251- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4252 to ``PyTuple_SetItem``, it can be used to populate a brand new
4253 frozenset; but it does not steal a reference to the added item.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00004255- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004257- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4258 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4259 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004260
4261- Patch #1720595: add T_BOOL to the range of structmember types.
4262
4263- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4264 ``PyFloat_GetInfo()`` to the float API.
4265
Georg Brandl3ee81df2008-05-17 18:14:43 +00004266- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4267 of w# format code incorrectly truncated the length to an int, even
4268 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4269 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004270
Georg Brandl3ee81df2008-05-17 18:14:43 +00004271- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4272 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004273
Georg Brandl3ee81df2008-05-17 18:14:43 +00004274- PEP 3123: Provide forward compatibility with Python 3.0, while
4275 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4276 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004277
Georg Brandl3ee81df2008-05-17 18:14:43 +00004278- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4279 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004280
4281- Patch #1733960: Allow T_LONGLONG to accept ints.
4282
4283- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4284
Christian Heimes000a0742008-01-03 22:16:32 +00004285- Added a new API function ``PyImport_ImportModuleNoBlock``.
4286
Georg Brandl6caad7d2008-01-26 14:19:22 +00004287- Bug #1637022: Prefix AST symbols with _Py_.
4288
4289- Fix some leftovers from the conversion from int to Py_ssize_t
4290 (relevant to strings and sequences of more than 2**31 items).
4291
4292- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4293 outside of pystate.c and should not be necessary.
4294
Georg Brandl3ee81df2008-05-17 18:14:43 +00004295- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4296 absolute imports. In earlier versions they might have used relative
4297 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004298
Georg Brandl3ee81df2008-05-17 18:14:43 +00004299- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4300 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004301
Georg Brandl3ee81df2008-05-17 18:14:43 +00004302- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4303 macro so it can be used as an expression.

4308
Georg Brandl3ee81df2008-05-17 18:14:43 +00004309- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4310 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4311 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4312 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004313
Georg Brandl3ee81df2008-05-17 18:14:43 +00004314- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00004325- buildtools now raises a DeprecationWarning.
4326
Georg Brandl3ee81df2008-05-17 18:14:43 +00004327- Removed the macfs module. It had been deprecated since Python 2.5.
4328 This lead to the deprecation of macostools.touched() as it relied
4329 solely on macfs and was a no-op under OS X.
