11
12Core and Builtins
13-----------------
14
Mark Dickinson2f865b92009-06-30 15:32:30 +000015- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
16 This fixes a build failure on HP-UX: int32_t and uint32_t are
17 defined in inttypes.h instead of stdint.h on that platform.
18
Hirokazu Yamamotoa3c56092009-06-28 10:23:00 +000019- Issue #4856: Remove checks for win NT.
20
Amaury Forgeot d'Arc595f7a52009-06-25 22:29:29 +000021- Issue #2016: Fixed a crash in a corner case where the dictionary of keyword
22 arguments could be modified during the function call setup.
23
Amaury Forgeot d'Arc14fc6732009-06-23 21:09:09 +000024- Removed the ipaddr module.
25
Raymond Hettinger62641e92009-06-23 20:59:43 +000026- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
27 because it wasn't recognized as a sequence).
28
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +000029- Issue #6289: Encoding errors from compile() were being masked.
30
Benjamin Petersona72be3b2009-06-13 20:23:33 +000031- When no module is given in a relative import, the module field of the
32 ImportFrom AST node is now None instead of an empty string.
33
Benjamin Peterson565e1b62009-06-13 03:46:30 +000034- Assignment to None using import statements now raises a SyntaxError.
35
Benjamin Peterson4afbba32009-06-13 01:40:00 +000036- In the slice AST type, the step field will always be None if a step expression
37 is not specified.
38
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +000039- Issue #4547: When debugging a very large function, it was not always
40 possible to update the lineno attribute of the current frame.
41
Antoine Pitrou46dbe272009-05-30 21:27:00 +000042- Issue #5330: C functions called with keyword arguments were not reported by
43 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
44
Raymond Hettinger578a2282009-05-29 04:58:52 +000045- Issue #5982: staticmethod and classmethod now expose the wrapped
46 function with __func__.
47
Raymond Hettinger822b87f2009-05-29 01:46:48 +000048- Added support for multiple context managers in the same with-statement.
49 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +000050
Benjamin Peterson1880d8b2009-05-25 13:13:44 +000051- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
52 statement and correctly lookup the __enter__ and __exit__ special methods.
53
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000054- Issue #5829: complex("1e500") no longer raises OverflowError. This
55 makes it consistent with float("1e500") and interpretation of real
56 and imaginary literals.
57
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +000058- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
59
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +000060- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
61 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +000062
R. David Murray525cffc2009-05-13 13:07:14 +000063- Issue #5994: the marshal module now has docstrings.
64
Mark Dickinsonb1d45852009-05-11 15:33:08 +000065- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
66 (1) inf and nan strings with trailing whitespace were incorrectly
67 rejected; (2) parsing of strings representing infinities and nans
68 was locale aware; and (3) the interpretation of fromhex('-nan')
69 didn't match that of float('-nan').
70
Eric Smitha985a3a2009-05-05 18:26:08 +000071- Issue #5920: For float.__format__, change the behavior with the
72 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
73 to be like 'g' but with at least one decimal point and with a
74 default precision of 12. Previously, the behavior the same but with
75 a default precision of 6. This more closely matches str(), and
76 reduces surprises when adding alignment flags to the empty
77 presentation type. This also affects the new complex.__format__ in
78 the same way.
79
R. David Murray7ba8e1c2009-05-04 22:16:24 +000080- Issue #5890: in subclasses of 'property' the __doc__ attribute was
81 shadowed by classtype's, even if it was None. property now
82 inserts the __doc__ into the subclass instance __dict__.
83
Antoine Pitrou653dece2009-05-04 18:32:32 +000084- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
85 sequences. Patch by Nick Barnes and Victor Stinner.
86
Vinay Sajipf9b01fe2009-05-09 12:07:17 +000087- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +000088 format(complex(1, 2./3), '.5') now produces a sensible result.
89
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000090- Issue #5864: Fix empty format code formatting for floats so that it
91 never gives more than the requested number of significant digits.
92
Eric Smithcac7af62009-04-27 19:04:37 +000093- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
94 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
95
Martin v. Löwis99f27792009-04-26 00:53:18 +000096- Issue #4971: Fix titlecase for characters that are their own
97 titlecase, but not their own uppercase.
98
Eric Smith068f0652009-04-25 21:40:15 +000099- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
100 _PyOS_double_to_string or PyOS_double_to_string.
101
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000102- Issue #5283: Setting __class__ in __del__ caused a segfault.
103
Mark Dickinson95bc9802009-04-24 12:46:53 +0000104- Issue #5816: complex(repr(z)) now recovers z exactly, even when
105 z involves nans, infs or negative zeros.
106
Eric Smithaca19e62009-04-22 13:29:05 +0000107- Implement PEP 378, Format Specifier for Thousands Separator, for
108 floats, ints, and longs.
109
110- Issue #5515: 'n' formatting for ints, longs, and floats handles
111 leading zero formatting poorly.
112
113- Issue #5772: For float.__format__, don't add a trailing ".0" if
114 we're using no type code and we have an exponent.
115
Mark Dickinson6736cf82009-04-20 21:13:33 +0000116- Issue #3166: Make long -> float (and int -> float) conversions
117 correctly rounded.
118
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000119- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
120 some builtin types.
121
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000122- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000123 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000124
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000125- Issue #5759: float() didn't call __float__ on str subclasses.
126
Georg Brandl3c4a5462009-04-12 12:08:12 +0000127- Issue #5704: the "-3" command-line option now implies "-t".
128
R. David Murray0374a822009-04-09 21:54:50 +0000129- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
130 its clarity and its speed.
131
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000132- Issue #2396: the memoryview object was backported from Python 3.1.
133
Georg Brandld3f03fa2009-04-02 18:09:04 +0000134- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

136
Brett Cannon15ba4da2009-04-01 18:03:59 +0000137- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
138
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000139- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
140 the end sys.path, for compatibility with the system install of Python.
141
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000142- Issue #4688: Add a heuristic so that tuples and dicts containing only
143 untrackable objects are not tracked by the garbage collector. This can
144 reduce the size of collections and therefore the garbage collection overhead
145 on long-running programs, depending on their particular use of datatypes.
146
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000147- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
148 improve its performance. Long divisions and remainder operations
149 are now between 50% and 150% faster.
150
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000151- Issue #4258: Make it possible to use base 2**30 instead of base
152 2**15 for the internal representation of integers, for performance
153 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
154 --enable-big-digits option to configure, which overrides the
155 default. Add sys.long_info structseq to provide information about
156 the internal format.
157
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000158- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
159 result traceback.__members__ no longer exists.)
160
Mark Dickinson6b265f12009-03-18 16:07:26 +0000161- Issue #4474: PyUnicode_FromWideChar now converts characters outside
162 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
163 and sizeof(Py_UNICODE) == 2.
164
Eric Smith6f42edb2009-03-14 11:57:26 +0000165- Issue #5237: Allow auto-numbered fields in str.format(). For
166 example: '{} {}'.format(1, 2) == '1 2'.
167
Brett Cannon6c4cff02009-03-11 04:51:06 +0000168- Issue #3652: Make the 'line' argument for warnings.showwarning() a
169 requirement. Means the DeprecationWarning from Python 2.6 can go away.
170
Eric Smithe9fb6862009-02-20 14:02:36 +0000171- Issue #5247: Improve error message when unknown format codes are
172 used when using str.format() with str, unicode, long, int, and
173 float arguments.
174
Raymond Hettinger08259e82009-02-18 23:10:19 +0000175- Running Python with the -3 option now also warns about classic division
176 for ints and longs.
177
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000178- Issue #5260: Long integers now consume less memory: average
179 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
180 on a 64-bit system.
181
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000182- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
183 rotating the object pointer by 4 bits to the right.
184
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000185- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
186 it now forces its argument to double before testing for infinity.
187
Benjamin Petersone18ef192009-01-20 14:21:16 +0000188- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
189
Georg Brandl29c6a282009-04-05 20:23:13 +0000190- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000191 were suppressing all exceptions. These include list(), filter(), map(),
192 zip(), and bytearray().
193
Benjamin Peterson596d3062009-01-19 15:42:23 +0000194- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
195 functions.
196
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000197- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
198 OSError.
199

201
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000202- Issue #4935: The overflow checking code in the expandtabs() method common
203 to str, bytes and bytearray could be optimized away by the compiler, letting
204 the interpreter segfault instead of raising an error.
205
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000206- Issue #3720: Fix a crash when an iterator modifies its class and removes its
207 __next__ method.
208

212
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000213- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
214 collecting the oldest generation) so that allocating lots of objects without
215 destroying them does not show quadratic performance. Based on a proposal by
216 Martin von Löwis at
217 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
218
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000219- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
220
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000221- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
222 an existing .py counterpart, override the co_filename attributes of all
223 code objects if the original filename is obsolete (which can happen if the
224 file has been renamed, moved, or if it is accessed through different paths).
225 Patch by Ziga Seilnacht and Jean-Paul Calderone.
226
Martin v. Löwis5344c992009-01-02 20:32:55 +0000227- Issue #4075: Use OutputDebugStringW in Py_FatalError.
228
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000229- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
230 file with `str' filename on Windows.

236 where the tp_hash and tp_dict slots are both NULL.
237
Benjamin Peterson7af65562008-12-29 17:56:58 +0000238- Issue #4764: With io.open, IOError.filename is set when trying to open a
239 directory on POSIX systems.
240
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000241- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
242 systems.

248 fail.
249
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000250- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
251 print elapsed times, not only when some objects are uncollectable /
252 unreachable. Original patch by Neil Schemenauer.
253
Mark Dickinson1a707982008-12-17 16:14:37 +0000254- Issue #3439: Add a bit_length method to int and long.
255
Antoine Pitroud0c35152008-12-17 00:38:28 +0000256- Issue #2183: Simplify and optimize bytecode for list comprehensions.
257 Original patch by Neal Norwitz.
258
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000259- Issue #4597: Fixed exception handling when the __exit__ function of a
260 context manager returns a value that cannot be converted to a bool.
261
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000262- Issue #4597: Fixed several opcodes that weren't always propagating
263 exceptions.
264
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000265- Issue #4445: Replace "sizeof(PyStringObject)" with
266 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
267 str instances. On a typical machine this saves 3 bytes of memory
268 (on average) per string allocation.
269
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000270- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
271 interpreter to abort ("Fatal Python error: Could not reset the stack!")
272 instead of throwing a MemoryError.
273
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000274- Issue #3689: The list reversed iterator now supports __length_hint__
275 instead of __len__. Behavior now matches other reversed iterators.
276

278 module couldn't be imported and \N escapes were present.
279
Vinay Sajip213faca2008-12-03 23:22:58 +0000280- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000281 method on file objects with closefd=False. The file descriptor is still
282 kept open but the file object behaves like a closed file. The ``FileIO``
283 object also got a new readonly attribute ``closefd``.
284
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000285- Issue #4348: Some bytearray methods returned that didn't cause any change to
286 the bytearray, returned the same bytearray instead of a copy.
287

295 exec statement.
296
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000297- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
298 method does not return iterators for the 4th and 5th items.
299
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000300- Issue #4209: Enabling unicode_literals and the print_function in the same
301 __future__ import didn't work.
302

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001304- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1305
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001306- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1307 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1308 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1309 ``printf`` function, whereas PyString_FromFormat has an independent
1310 implementation and uses "%zd" on all platforms for size_t values.
1311 This makes a difference on win64, where ``printf`` needs "%Id" to display
1312 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00001314- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1318 object; previously an int would be returned for small values. the __long__

1321
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001322- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001328 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001329 was correctly parsed but parsing of subsequent arguments failed.
1330
Vinay Sajip35e3b032008-09-01 14:33:59 +00001331- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001332 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1333 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1334 when given a tuple of classes as second argument, were looking up
1335 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1336 type object.
1337
Neal Norwitz18aa3882008-08-24 05:04:52 +00001338- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001434- Issue #2975: When compiling several extension modules with Visual Studio 2008
1435 from the same python interpreter, some environment variables would grow
1436 without limit.
1437
Benjamin Peterson37346b22008-08-23 20:27:43 +00001438- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001475What's New in Python 2.6 beta 3?
1476================================
1477
Barry Warsaw07a4a382008-08-21 01:15:08 +00001478*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001479
1480Core and Builtins
1481-----------------
1482
Guido van Rossumf8402962008-08-20 15:01:50 +00001483- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1484 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1485 extensions do not automatically benefit from the class attribute
1486 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1487 to their tp_flags field if they care. This is a backwards
1488 compatibility feature; in 3.0, all types will use the cache by
1489 default.
1490
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001491- Keyword arguments can now follow starred arguments. (``f(a, *args,
1492 keyword=23)`` is now valid syntax.)
1493
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001494- ctypes function pointers that are COM methods have a boolean True
1495 value again.
1496
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001497- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1498 by denying s# to parse objects that have a releasebuffer procedure,
1499 and introducing s*.
1500
Georg Brandl1e13ea92008-08-11 09:07:59 +00001501- Issue #3537: Fix an assertion failure when an empty but presized dict
1502 object was stored in the freelist.
1503
Mark Dickinsonb6467572008-08-04 21:30:09 +00001504- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1505 ValueError consistently across platforms.
1506
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001507- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1508 (64bit Unix, for example), unichr() would truncate its argument and return
1509 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1510
Neal Norwitze7d8be82008-07-31 17:17:14 +00001511- Apply security patches from Apple.
1512
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001513- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1514 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1515
Antoine Pitrou92f82162008-07-25 22:22:08 +00001516- Issue #1819: function calls with several named parameters are now on
1517 average 35% faster (as measured by pybench).
1518
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001519- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1520 the python debugger steps into a class statement: the free variables (local
1521 variables defined in an outer scope) would be deleted from the outer scope.
1522
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001523- Issue #2620: Overflow checking when allocating or reallocating memory
1524 was not always being done properly in some python types and extension
1525 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1526 all been updated to perform better checks and places in the code that
1527 would previously leak memory on the error path when such an allocation
1528 failed have been fixed.
1529
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001530Library
1531-------
1532
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001533- Issue #3612: Added some missing basic types in ctypes.wintypes.
1534
Benjamin Petersone977ad42008-08-20 01:42:01 +00001535- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1536 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1537
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001538- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1539 version reported by these tools does not necessarily follow the python
1540 version numbering scheme, so the module is less strict when parsing it.
1541
Nick Coghlanf70385a2008-08-18 12:42:46 +00001542- Issue #2235: Added Py3k warnings for types which will become unhashable
1543 under the stricter __hash__ inheritance rules in 3.0. Several types
1544 which did not meet the rules for hash invariants and were already
1545 unhashable in 3.0 have now been explicitly flagged as unhashable in
1546 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1547 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1548
Brett Cannon88f801d2008-08-18 00:46:22 +00001549- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1550 imported into the module but exposed as part of the module's API.
1551
Brett Cannon7b96f072008-08-18 00:41:11 +00001552- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1553
Brett Cannon46225e72008-08-18 00:36:52 +00001554- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001556- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1557
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001558- Issue #3575: Incremental decoder's decode function now takes bytearray
1559 by using 's*' instead of 't#'.
1560
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001561- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001562 fails unicode conversion on 2nd parameter. (windows only)
1563
Facundo Batista94f243a2008-08-17 03:38:39 +00001564- Issue 2464. urllib2 now supports a malformation in the URL received
1565 in a redirect.
1566
Brett Cannonabe423e2008-08-16 21:47:07 +00001567- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001568 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001569
Facundo Batistaeb90b782008-08-16 14:44:07 +00001570- Issue #2776: fixed small issue when handling an URL with double slash
1571 after a 302 response in the case of not going through a proxy.
1572
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001573- Issue #2676: in the email package, content-type parsing was hanging on
1574 pathological input because of quadratic or exponential behaviour of a
1575 regular expression.
1576
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001577- Issue #3476: binary buffered reading through the new "io" library is now
1578 thread-safe.
1579
Brett Cannonbf3157b2008-08-14 05:00:03 +00001580- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1581 since mimetools itself is deprecated. Because modules are cached, all
1582 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1583
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001584- Issue #3134: shutil referenced undefined WindowsError symbol.
1585
Robert Schuppenies14646332008-08-10 11:01:53 +00001586- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1587 menu entries were not deleted.
1588
Brett Cannon83e81842008-08-09 23:30:55 +00001589- Copied the implementation of reduce() to _functools.reduce() to have a
1590 version that did not raise a DeprecationWarning under -3.
1591
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001592- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1593 a MemoryError rather than silently stop the iteration.
1594
Guido van Rossum59ce9012008-08-09 14:55:34 +00001595- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1596 to _sre.compile() will now be rejected. This should not affect anybody
1597 since the re.compile() function never generates invalid re-bytecode.
1598
Skip Montanaroa032bf42008-08-08 22:52:51 +00001599- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1600 upon first access it can be automatically initialized from the csv file if
1601 it wasn't initialized during instantiation.
1602
Brett Cannon3aa2a492008-08-06 22:28:09 +00001603- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1604 the reload() built-in has been removed.
1605
Brett Cannon7e30b672008-08-04 21:52:25 +00001606- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001607 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001614- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1615 raised an AttributeError.
1616
Benjamin Peterson01a24322008-07-28 23:35:27 +00001617- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001618 asking for a specific length. This problem only affected files opened
1619 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001620
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001621- Issue #3449: Update decimal module to use most recent specification
1622 (v. 1.68) and tests (v. 2.58) from IBM.
1623
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001624- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1625

1632
1633- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1634 invalid arguments.
1635
1636- Issue #3302: Fix several crashes when calling locale's gettext functions
1637 with None arguments.
1638
1639- Issue #3389: Allow resolving dotted names for handlers in logging
1640 configuration files.
1641
1642- Deprecate the sunaudio module for removal in Python 3.0.
1643
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001644- Issue #3394: zipfile.writestr sets external attributes when passed a
1645 file name rather than a ZipInfo instance, so files are extracted with
1646 mode 0600 rather than 000 under Unix.
1647
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001648- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1649 argument in python 2.5, this broke code that subclassed Popen to include its
1650 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1659
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001660- Issue #2235: the C API function PyObject_HashNotImplemented and its
1661 interaction with the tp_hash slot (added in 2.6b2) are now documented
1662
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001663- Issue #643841: The language reference now provides more detailed
1664 coverage of the lookup process for special methods. The disclaimers
1665 regarding lack of coverage of new-style classes have also been
1666 removed, since the coverage is now fairly reasonable.

1671
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001672*Release date: 17-Jul-2008*

1675-----------------
1676
Georg Brandl3e483f62008-07-16 22:57:41 +00001677- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1678 its methods now allow for items objects that can be converted to
1679 an integer using operator.index().
1680
Mark Dickinson64b7e502008-07-16 09:40:03 +00001681- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1682 produced a ValueError instead of giving the correct float.
1683
Eric Smitha5fa5a22008-07-16 00:11:49 +00001684- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1685 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1686
Mark Dickinson7103aa42008-07-15 19:08:33 +00001687- Issue #3008: the float type has a new instance method 'float.hex'
1688 and a new class method 'float.fromhex' to convert floating-point
1689 numbers to and from hexadecimal strings, respectively.
1690
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001691- Issue #2235: __hash__ is once again inherited by default. To allow
1692 collections.Hashable to remain meaningful in the presence of the
1693 default hash implementation (object.__hash__), it is now possible
1694 to explicit block inheritance of hash by setting __hash__=None at
1695 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1696 level.
1697
Nick Coghlanb028f502008-07-13 14:52:36 +00001698- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1699 the parent module cannot be found while performing an absolute import.
1700 This means that an incorrectly defined __package__ attribute will
1701 now only prevent relative imports in that module rather than causing
1702 all imports from that module to fail.
1703
Nick Coghlan14ff9942008-07-08 14:21:42 +00001704- Issue #2517: Allow unicode messages in Exceptions again by correctly
1705 bypassing the instance dictionary when looking up __unicode__ on
1706 new-style classes.
1707
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001708- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1709 set to a custom object whose write() method happens to install
1710 another file in sys.stdout.

1714 another thread's dictionary.
1715
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001716- Issue #3004: Minor change to slice.indices(): the start and stop
1717 arguments are now treated identically, making the behaviour easier
1718 to describe and understand. For example, slice(None, -10,
1719 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1720 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1721 10, -1).
1722
Georg Brandl278fc502008-07-19 12:46:12 +00001723- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00002175 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002176
2177 This is controlled by the configure argument ``--with-universal-archs``:
2178

2180
2181 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2182
2183 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2184

2224 two handlers that derive the same default base class.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002237- Issue #1631171: Re-implement the 'warnings' module in C (the
2238 original Python code has been kept as backup). This will allow for
2239 using the 'warning's machinery in such places as the parser where
2240 use of pure Python code is not possible. Both the ``showarning()``
2241 and ``formatwarning()`` gain an optional 'line' argument which is
2242 not called by default for backwards-compatibility reasons. Setting
2243 ``warnings.showwarning()`` to an implementation that lacks support
2244 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002307- Issue #2550: The approach used by client/server code for obtaining
2308 ports to listen on in network-oriented tests has been refined in an
2309 effort to facilitate running multiple instances of the entire
2310 regression test suite in parallel without issue.
2311 test_support.bind_port() has been fixed such that it will always
2312 return a unique port -- which wasn't always the case with the
2313 previous implementation, especially if socket options had been set
2314 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2315 new implementation of bind_port() will actually raise an exception
2316 if it is passed an AF_INET/SOCK_STREAM socket with either the
2317 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2318 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2319 the socket it's been passed. This currently only applies to
2320 Windows. This option prevents any other sockets from binding to the
2321 host/port we've bound to, thus removing the possibility of the
2322 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2323 when a second SOCK_STREAM socket binds and accepts to a host/port
2324 that's already been bound by another socket. The optional preferred
2325 port parameter to bind_port() has been removed. Under no
2326 circumstances should tests be hard coding ports!
2327
2328 test_support.find_unused_port() has also been introduced, which will
2329 pass a temporary socket object to bind_port() in order to obtain an
2330 unused port. The temporary socket object is then closed and
2331 deleted, and the port is returned. This method should only be used
2332 for obtaining an unused port in order to pass to an external program
2333 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2334 a parameter to a server-oriented class that doesn't give you direct
2335 access to the underlying socket used.
2336
2337 Finally, test_support.HOST has been introduced, which should be used
2338 for the host argument of any relevant socket calls (i.e. bind and
2339 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002340
2341 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002342 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002343 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2344 test_asynchat and test_socket_ssl.
2345
Georg Brandl3ee81df2008-05-17 18:14:43 +00002346 It is now possible for multiple instances of the regression test
2347 suite to run in parallel without issue.

2613Core and builtins
2614-----------------
2615
Fred Drakea8ee94b2008-03-01 02:45:07 +00002616- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002617 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002618
Georg Brandlad61bc82008-02-23 15:11:18 +00002619- Issue #2067: file.__exit__() now calls subclasses' close() method.
2620
2621- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002622
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002623- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002624 issue 215555 for a discussion.
2625
Eric Smitha73fbe72008-02-23 03:09:44 +00002626- Added the future_builtins module, which contains hex() and oct().
2627 These are the PEP 3127 version of these functions, designed to be
2628 compatible with the hex() and oct() builtins from Python 3.0. They
2629 differ slightly in their output formats from the existing, unchanged
2630 Python 2.6 builtins. The expected usage of the future_builtins
2631 module is:
2632 from future_builtins import hex, oct
2633
Eric Smith7ef40bf2008-02-20 23:34:22 +00002634- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2635 exponents for exponents with absolute value < 100. Follows C99
2636 standard. This is a change on Windows, which would use 3 digits.
2637 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2638 so that any alterations it does to the resulting string will be
2639 available in stringlib/formatter.h (for float.__format__).
2640
Eric Smith5a3c1352008-02-19 13:21:56 +00002641- Implemented PEP 3101, Advanced String Formatting. This adds a new
2642 builtin format(); a format() method for str and unicode; a
2643 __format__() method to object, str, unicode, int, long, float, and
2644 datetime; the class string.Formatter; and the C API
2645 PyObject_Format().
2646
Georg Brandl3ee81df2008-05-17 18:14:43 +00002647- Fixed several potential crashes, all caused by specially crafted
2648 __del__ methods exploiting objects in temporarily inconsistent
2649 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002650
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002651- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002652 prevent a possible crash: an Abstract Base Class would try to access
2653 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002654
Georg Brandl3ee81df2008-05-17 18:14:43 +00002655- Fixed repr() and str() of complex numbers with infinity or nan as
2656 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002657
Georg Brandl3ee81df2008-05-17 18:14:43 +00002658- Clear all free lists during a gc.collect() of the highest generation
2659 in order to allow pymalloc to free more arenas. Python may give back
2660 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002661
Georg Brandl3ee81df2008-05-17 18:14:43 +00002662- Issue #2045: Fix an infinite recursion triggered when printing a
2663 subclass of collections.defaultdict, if its default_factory is set
2664 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002665
Christian Heimesf75dbef2008-02-08 00:11:31 +00002666- Fixed a minor memory leak in dictobject.c. The content of the free
2667 list was not freed on interpreter shutdown.
2668
Georg Brandl3ee81df2008-05-17 18:14:43 +00002669- Limit free list of method and builtin function objects to 256
2670 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002671
Georg Brandl3ee81df2008-05-17 18:14:43 +00002672- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2673 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002674 to compact the internal free lists of pre-allocted ints and floats.
2675
Georg Brandl3ee81df2008-05-17 18:14:43 +00002676- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2677 calls. Python expected the return type int but the fork familie
2678 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002679
Georg Brandl3ee81df2008-05-17 18:14:43 +00002680- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2681 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002682
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2684 with the collections.Sequence API.

2690 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002691
Georg Brandl3ee81df2008-05-17 18:14:43 +00002692- Patch #1473257: generator objects gain a gi_code attribute. This is
2693 the same object as the func_code attribute of the function that
2694 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002695
Georg Brandl3ee81df2008-05-17 18:14:43 +00002696- Issue #1920: "while 0" statements were completely removed by the
2697 compiler, even in the presence of an "else" clause, which is
2698 supposed to be run when the condition is false. Now the compiler
2699 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002700
Guido van Rossumeead05f2008-01-24 18:21:02 +00002701- A few crashers fixed: weakref_in_del.py (issue #1377858);
2702 loosing_dict_ref.py (issue #1303614, test67.py);
2703 borrowed_ref_[34].py (not in tracker).
2704
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002705- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002706 suppressed while an extension is loaded by calling SetErrorMode in
2707 dynload_win.c. The error is still reported properly.
2708
Georg Brandl3ee81df2008-05-17 18:14:43 +00002709- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002710 several extension methods and modules do not work without unicode
2711 support.
2712
Georg Brandl26543b12008-01-21 18:36:51 +00002713- Issue #1882: when compiling code from a string, encoding cookies in the
2714 second line of code were not always recognized correctly.
2715
Georg Brandl14404b62008-01-19 19:27:05 +00002716- Issue #1679: "0x" was taken as a valid integer literal.
2717
Georg Brandl6caad7d2008-01-26 14:19:22 +00002718- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002719 added.
2720
Christian Heimesc94e2b52008-01-14 04:13:37 +00002721- sys.float_info / PyFloat_GetInfo: The floating point information
2722 object was converted from a dict to a specialized structseq object.
2723
Georg Brandl3ee81df2008-05-17 18:14:43 +00002724- Patch #1816: Added sys.flags structseq. It exposes the status of
2725 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002726
Georg Brandl3ee81df2008-05-17 18:14:43 +00002727- Objects/structseq.c: Implemented new structseq representation. The

2729 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002730
Georg Brandl3ee81df2008-05-17 18:14:43 +00002731- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002743- Improve some exception messages when Windows fails to load an
2744 extension module. Now we get for example '%1 is not a valid Win32
2745 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002753 and INF. float("nan"), float("inf") and float("-inf") now work on
2754 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002755
Georg Brandl3ee81df2008-05-17 18:14:43 +00002756- Compiler now generates simpler and faster code for dictionary
2757 literals. The oparg for BUILD_MAP now indicates an estimated
2758 dictionary size. There is a new opcode, STORE_MAP, for adding
2759 entries to the dictionary.

Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002787
Georg Brandl3ee81df2008-05-17 18:14:43 +00002788- Patch #1739468: Directories and zipfiles containing a __main__.py
2789 file can now be directly executed by passing their name to the
2790 interpreter. The directory/zipfile is automatically inserted as the
2791 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002792
Georg Brandl3ee81df2008-05-17 18:14:43 +00002793- Issue #1265: Fix a problem with sys.settrace, if the tracing
2794 function uses a generator expression when at the same time the
2795 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002796
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002797- sets and frozensets now have an isdisjoint() method.
2798

2800
Neal Norwitz44f326e2007-10-05 05:29:17 +00002801- Fix warnings found by the new version of the Coverity checker.
2802
Georg Brandl3ee81df2008-05-17 18:14:43 +00002803- The enumerate() builtin function is no longer bounded to sequences
2804 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2805 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002806
Georg Brandl3ee81df2008-05-17 18:14:43 +00002807- Issue #1686386: Tuple's tp_repr did not take into account the
2808 possibility of having a self-referential tuple, which is possible
2809 from C code. Nor did object's tp_str consider that a type's tp_str
2810 could do something that could lead to an inifinite recursion.
2811 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2812 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002813
Georg Brandl3ee81df2008-05-17 18:14:43 +00002814- Issue #1164: It was possible to trigger deadlock when using the
2815 'print' statement to write to a file since the GIL was not released
2816 as needed. Now PyObject_Print() does the right thing along with
2817 various tp_print implementations of the built-in types and those in
2818 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002819
Georg Brandl3ee81df2008-05-17 18:14:43 +00002820- Issue #1147: Exceptions were directly allowing string exceptions in
2821 their throw() method even though string exceptions no longer
2822 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002823
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Issue #1096: Prevent a segfault from getting the repr of a very
2825 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002826
Brett Cannon1e534b52007-09-07 04:18:30 +00002827- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828 PyObject_Call() never calling back out to Python code to trigger
2829 recursion depth updates/checks. Required the creation of a static
2830 RuntimeError instance in case normalizing an exception put the
2831 recursion check value past its limit. Fixes crashers
2832 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002833
Georg Brandl3ee81df2008-05-17 18:14:43 +00002834- Patch #1031213: Decode source line in SyntaxErrors back to its

2838 with %G.
2839
Georg Brandl3ee81df2008-05-17 18:14:43 +00002840- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002847- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002848 __*__ attributes. (Some already existed, e.g., __doc__ and
2849 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002850
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002851- Add -3 option to the interpreter to warn about features that are
2852 deprecated and will be changed/removed in Python 3.0.
2853
Georg Brandl2134e752007-05-21 20:34:16 +00002854- Patch #1686487: you can now pass any mapping after '**' in function
2855 calls.
2856
Collin Winter62903052007-05-18 23:11:24 +00002857- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002858 "except E as target:". This is to provide forwards compatibility
2859 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002860
Brett Cannon229cee22007-05-05 01:34:02 +00002861- Deprecate BaseException.message as per PEP 352.
2862
Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002864 inherited from a builtin base.
2865
Vinay Sajip8549ce32007-05-06 17:53:37 +00002866- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002867 setting a plain string, ie don't expand to single letter identifiers.
2868
Raymond Hettinger13936692007-04-11 18:40:58 +00002869- Request #1191699: Slices can now be pickled.
2870
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002871- Request #1193128: str.translate() now allows a None argument for
2872 translations that only remove characters without re-mapping the
2873 remaining characters.
2874
Georg Brandl5cb76c12007-03-21 09:00:39 +00002875- Patch #1682205: a TypeError while unpacking an iterable is no longer
2876 masked by a generic one with the message "unpack non-sequence".
2877
Neal Norwitzaa754b72007-03-21 06:39:48 +00002878- Remove unused file Python/fmod.c.
2879
Guido van Rossum143b5642007-03-23 04:58:42 +00002880- Bug #1683368: The object.__init__() and object.__new__() methods are
2881 now stricter in rejecting excess arguments. The only time when
2882 either allows excess arguments is when it is not overridden and the
2883 other one is. For backwards compatibility, when both are
2884 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002885 warning later). Also, type.__init__() insists on the same signature
2886 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2889 object to complex using its __complex__() method before falling back
2890 to the __float__() method. Therefore, the functions in the cmath
2891 module now can operate on objects that define a __complex__()
2892 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002893
Georg Brandl3ee81df2008-05-17 18:14:43 +00002894- Patch #1623563: allow __class__ assignment for classes with
2895 __slots__. The old and the new class are still required to have the
2896 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002897

2902 ``object.__reduce_ex__()`` is called with an object that is faking
2903 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002904
Georg Brandl3ee81df2008-05-17 18:14:43 +00002905- Patch #1680015: Don't modify __slots__ tuple if it contains an

2909
Georg Brandl7b9c5552007-03-12 14:30:05 +00002910- Bug #1678647: write a newline after printing an exception in any
2911 case, even when converting the value to a string failed.
2912
Georg Brandl871f1bc2007-03-12 13:17:36 +00002913- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914 its argument, if it exists. If not, it will work like before. This
2915 allows customizing the output of dir() in the presence of a
2916 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002917
Collin Winter276887b2007-03-12 16:11:39 +00002918- Patch #922167: Python no longer segfaults when faced with infinitely
2919 self-recursive reload() calls (as reported by bug #742342).
2920
Georg Brandl3ee81df2008-05-17 18:14:43 +00002921- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002924- Patch #1491866: change the complex() constructor to allow
2925 parthensized forms. This means complex(repr(x)) now works instead of
2926 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002927
Georg Brandlaa2321b2007-03-07 00:40:28 +00002928- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002929 makes the filenames the warning module prints much more sensible
2930 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002931
Georg Brandl49aafc92007-03-07 00:34:46 +00002932- Variant of patch #697613: don't exit the interpreter on a SystemExit
2933 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002934 variable is given, but break into the interactive interpreter just
2935 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002942
Georg Brandl0fca97a2007-03-05 22:28:08 +00002943- Patch #1674228: when assigning a slice (old-style), check for the
2944 sq_ass_slice instead of the sq_slice slot.
2945
Georg Brandl3ee81df2008-05-17 18:14:43 +00002946- When printing an unraisable error, don't print exceptions. before
2947 the name. This duplicates the behavior whening normally printing
2948 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002949
Georg Brandl3ee81df2008-05-17 18:14:43 +00002950- Bug #1653736: Properly discard third argument to

3005
Armin Rigo7ccbca92006-10-04 12:17:45 +00003006- A number of places, including integer negation and absolute value,

3576 -- the failure just occurred later, with a more cumbersome
3577 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3859 with RFC 3207 and forgets any knowledge obtained from the server not
3860 obtained from the TLS negotiation itself. Patch contributed by Bill
3861 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003862
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003864 that the SMTP.starttls() caller no longer needs to call ehlo()
3865 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003866 does not claim to support starttls. Adds the
3867 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3948 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3949 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00003951

Georg Brandl3ee81df2008-05-17 18:14:43 +00003966 time so that opening a database previously created with the DB_DUP
3967 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3968 opens. Specifically: dictionary assignment to a DB object will
3969 replace all values for a given key when the database allows
3970 duplicate values. DB users should use DB.put(k, v) when they want
3971 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003972

3978 characters with ASCII value less than 32. Also, it correctly quotes
3979 dots only if they occur on a single line, as opposed to the previous
3980 behavior of quoting dots if they are the second character of any
3981 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003982

4304-----
4305
Georg Brandl3ee81df2008-05-17 18:14:43 +00004306- Unified naming convention for free lists and their limits. All free
4307 lists in Object/ are named ``free_list``, the counter ``numfree``
4308 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4309 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004310
Georg Brandl3ee81df2008-05-17 18:14:43 +00004311- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4312 to ``PyTuple_SetItem``, it can be used to populate a brand new
4313 frozenset; but it does not steal a reference to the added item.

4325
Georg Brandl3ee81df2008-05-17 18:14:43 +00004326- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4327 of w# format code incorrectly truncated the length to an int, even
4328 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4329 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004330
Georg Brandl3ee81df2008-05-17 18:14:43 +00004331- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4349- Fix some leftovers from the conversion from int to Py_ssize_t
4350 (relevant to strings and sequences of more than 2**31 items).
4351
4352- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4353 outside of pystate.c and should not be necessary.
4354
Georg Brandl3ee81df2008-05-17 18:14:43 +00004355- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4356 absolute imports. In earlier versions they might have used relative
4357 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004358
Georg Brandl3ee81df2008-05-17 18:14:43 +00004359- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4360 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004361
Georg Brandl3ee81df2008-05-17 18:14:43 +00004362- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4370 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4371 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4372 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004373

Georg Brandl3ee81df2008-05-17 18:14:43 +00004387- Removed the macfs module. It had been deprecated since Python 2.5.
4388 This lead to the deprecation of macostools.touched() as it relied
4389 solely on macfs and was a no-op under OS X.
