12Core and Builtins
13-----------------
14
Benjamin Petersond4d400c2009-04-18 20:12:47 +000015- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
16 some builtin types.
17
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000018- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
19 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
20
Benjamin Peterson99d36f12009-04-15 21:26:36 +000021- Issue #5759: float() didn't call __float__ on str subclasses.
22
Georg Brandl3c4a5462009-04-12 12:08:12 +000023- Issue #5704: the "-3" command-line option now implies "-t".
24
R. David Murray0374a822009-04-09 21:54:50 +000025- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
26 its clarity and its speed.
27
Antoine Pitrou789be0c2009-04-02 21:18:34 +000028- Issue #2396: the memoryview object was backported from Python 3.1.
29
Georg Brandld3f03fa2009-04-02 18:09:04 +000030- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
31 when hitting the recursion limit under certain circumstances.
32
Brett Cannon15ba4da2009-04-01 18:03:59 +000033- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
34
Ronald Oussorene0154ed2009-03-30 23:10:35 +000035- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
36 the end sys.path, for compatibility with the system install of Python.
37
Antoine Pitrouf8387af2009-03-23 18:41:45 +000038- Issue #4688: Add a heuristic so that tuples and dicts containing only
39 untrackable objects are not tracked by the garbage collector. This can
40 reduce the size of collections and therefore the garbage collection overhead
41 on long-running programs, depending on their particular use of datatypes.
42
Mark Dickinson0b666bf2009-03-23 18:25:13 +000043- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
44 improve its performance. Long divisions and remainder operations
45 are now between 50% and 150% faster.
46
Mark Dickinsonefc82f72009-03-20 15:51:55 +000047- Issue #4258: Make it possible to use base 2**30 instead of base
48 2**15 for the internal representation of integers, for performance
49 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
50 --enable-big-digits option to configure, which overrides the
51 default. Add sys.long_info structseq to provide information about
52 the internal format.
53
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000054- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
55 result traceback.__members__ no longer exists.)
56
Mark Dickinson6b265f12009-03-18 16:07:26 +000057- Issue #4474: PyUnicode_FromWideChar now converts characters outside
58 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
59 and sizeof(Py_UNICODE) == 2.
60
Eric Smith6f42edb2009-03-14 11:57:26 +000061- Issue #5237: Allow auto-numbered fields in str.format(). For
62 example: '{} {}'.format(1, 2) == '1 2'.
63
Brett Cannon6c4cff02009-03-11 04:51:06 +000064- Issue #3652: Make the 'line' argument for warnings.showwarning() a
65 requirement. Means the DeprecationWarning from Python 2.6 can go away.
66
Eric Smithe9fb6862009-02-20 14:02:36 +000067- Issue #5247: Improve error message when unknown format codes are
68 used when using str.format() with str, unicode, long, int, and
69 float arguments.
70
Raymond Hettinger08259e82009-02-18 23:10:19 +000071- Running Python with the -3 option now also warns about classic division
72 for ints and longs.
73
Mark Dickinson2ffb26f2009-02-15 10:13:41 +000074- Issue #5260: Long integers now consume less memory: average
75 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
76 on a 64-bit system.
77
Antoine Pitrou76a4b892009-02-13 13:52:33 +000078- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
79 rotating the object pointer by 4 bits to the right.
80
Mark Dickinsonc97c9092009-02-09 14:18:43 +000081- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
82 it now forces its argument to double before testing for infinity.
83
Benjamin Petersone18ef192009-01-20 14:21:16 +000084- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
85
Georg Brandl29c6a282009-04-05 20:23:13 +000086- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +000087 were suppressing all exceptions. These include list(), filter(), map(),
88 zip(), and bytearray().
89
Benjamin Peterson596d3062009-01-19 15:42:23 +000090- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
91 functions.
92
Benjamin Peterson5848d1f2009-01-19 00:08:08 +000093- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
94 OSError.
95
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +000096- Issue #4807: Port the _winreg module to Windows CE.
97
Antoine Pitrouc2f02212009-01-13 23:13:52 +000098- Issue #4935: The overflow checking code in the expandtabs() method common
99 to str, bytes and bytearray could be optimized away by the compiler, letting
100 the interpreter segfault instead of raising an error.
101
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000102- Issue #3720: Fix a crash when an iterator modifies its class and removes its
103 __next__ method.
104
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000105- Issue #4893: Use NT threading on CE.
106

108
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000109- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
110 collecting the oldest generation) so that allocating lots of objects without
111 destroying them does not show quadratic performance. Based on a proposal by
112 Martin von Löwis at
113 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
114
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000115- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
116
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000117- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
118 an existing .py counterpart, override the co_filename attributes of all
119 code objects if the original filename is obsolete (which can happen if the
120 file has been renamed, moved, or if it is accessed through different paths).
121 Patch by Ziga Seilnacht and Jean-Paul Calderone.
122
Martin v. Löwis5344c992009-01-02 20:32:55 +0000123- Issue #4075: Use OutputDebugStringW in Py_FatalError.
124
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000125- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
126 file with `str' filename on Windows.
127
Antoine Pitrouaa687902009-01-01 14:11:22 +0000128- Issue #3680: Reference cycles created through a dict, set or deque iterator
129 did not get collected.
130
Nick Coghlan180e4002008-12-30 01:18:48 +0000131- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
132 where the tp_hash and tp_dict slots are both NULL.
133
Benjamin Peterson7af65562008-12-29 17:56:58 +0000134- Issue #4764: With io.open, IOError.filename is set when trying to open a
135 directory on POSIX systems.
136
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000137- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
138 systems.
139
Georg Brandl6425a2f2008-12-28 11:54:53 +0000140- Issue #4759: None is now allowed as the first argument of
141 bytearray.translate(). It was always allowed for bytes.translate().
142
Skip Montanarof205c132008-12-23 03:30:15 +0000143- Added test case to ensure attempts to read from a file opened for writing
144 fail.
145
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000146- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
147 print elapsed times, not only when some objects are uncollectable /
148 unreachable. Original patch by Neil Schemenauer.
149
Mark Dickinson1a707982008-12-17 16:14:37 +0000150- Issue #3439: Add a bit_length method to int and long.
151
Antoine Pitroud0c35152008-12-17 00:38:28 +0000152- Issue #2183: Simplify and optimize bytecode for list comprehensions.
153 Original patch by Neal Norwitz.
154
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000155- Issue #4597: Fixed exception handling when the __exit__ function of a
156 context manager returns a value that cannot be converted to a bool.
157
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000158- Issue #4597: Fixed several opcodes that weren't always propagating
159 exceptions.
160
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000161- Issue #4445: Replace "sizeof(PyStringObject)" with
162 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
163 str instances. On a typical machine this saves 3 bytes of memory
164 (on average) per string allocation.
165
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000166- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
167 interpreter to abort ("Fatal Python error: Could not reset the stack!")
168 instead of throwing a MemoryError.
169
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000170- Issue #3689: The list reversed iterator now supports __length_hint__
171 instead of __len__. Behavior now matches other reversed iterators.
172
Benjamin Petersonc078f922008-11-21 22:27:24 +0000173- Issue #4367: Python would segfault during compiling when the unicodedata
174 module couldn't be imported and \N escapes were present.
175
Vinay Sajip213faca2008-12-03 23:22:58 +0000176- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000177 method on file objects with closefd=False. The file descriptor is still
178 kept open but the file object behaves like a closed file. The ``FileIO``
179 object also got a new readonly attribute ``closefd``.
180
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000181- Issue #4348: Some bytearray methods returned that didn't cause any change to
182 the bytearray, returned the same bytearray instead of a copy.
183
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000184- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
185
Benjamin Peterson273c2332008-11-17 22:39:09 +0000186- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
187
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000188- Issue #4048: The parser module now correctly validates relative imports.
189
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000190- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
191 exec statement.
192
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000193- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
194 method does not return iterators for the 4th and 5th items.
195
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000196- Issue #4209: Enabling unicode_literals and the print_function in the same
197 __future__ import didn't work.
198
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000199- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000200 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000201
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000202- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
203 returned a path longer than MAX_PATH. (But It's doubtful this code path is
204 really executed because I cannot move to such directory on win2k)
205
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000206- Issue #4069: When set.remove(element) is used with a set element, the element
207 is temporarily replaced with an equivalent frozenset. But the eventual
208 KeyError would always report the empty frozenset([]) as the missing key. Now
209 it correctly refers to the initial element.
210
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000211- Issue #4509: Various issues surrounding resize of bytearray objects to
212 which there are buffer exports.
213
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000214- Issue #4748: Lambda generators no longer return a value.
215
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +0000216- Issue #3582: Use native TLS functions on Windows
217
Gregory P. Smithae91d092009-03-02 05:13:57 +0000218- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
219
Matthias Kloseedb5e1e2009-04-04 14:18:13 +0000220- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
221 short file names.
222
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000223- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
224 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000225
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000226- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
227 returned them on 64bit platforms.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000928- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
929
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000930- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
931 PyString_FromFormat or PyErr_Format to display size_t values. The macro
932 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
933 ``printf`` function, whereas PyString_FromFormat has an independent
934 implementation and uses "%zd" on all platforms for size_t values.
935 This makes a difference on win64, where ``printf`` needs "%Id" to display
936 64bit values.
937
Benjamin Peterson97179b02008-09-09 20:55:01 +0000938- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
939 error.

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +0000941- Issue #3777: long() applied to a float object now always return a long
942 object; previously an int would be returned for small values. the __long__
943 method is allowed to return either an int or a long, but the behaviour of
944 float objects should not change to respect backward compatibility.
945
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000946- Issue #3751: str.rpartition would perform a left-partition when called with
947 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000952 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000953 was correctly parsed but parsing of subsequent arguments failed.
954
Vinay Sajip35e3b032008-09-01 14:33:59 +0000955- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000956 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
957 mechanism. In the process, fix a bug where isinstance() and issubclass(),
958 when given a tuple of classes as second argument, were looking up
959 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
960 type object.

1032 for catch_warnings() also led to an improvement in the raising of a

1105-----------------
1106
Guido van Rossumf8402962008-08-20 15:01:50 +00001107- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1108 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1109 extensions do not automatically benefit from the class attribute
1110 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1111 to their tp_flags field if they care. This is a backwards
1112 compatibility feature; in 3.0, all types will use the cache by
1113 default.
1114
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001115- Keyword arguments can now follow starred arguments. (``f(a, *args,
1116 keyword=23)`` is now valid syntax.)
1117
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001118- ctypes function pointers that are COM methods have a boolean True
1119 value again.
1120
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001121- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1122 by denying s# to parse objects that have a releasebuffer procedure,
1123 and introducing s*.
1124
Georg Brandl1e13ea92008-08-11 09:07:59 +00001125- Issue #3537: Fix an assertion failure when an empty but presized dict
1126 object was stored in the freelist.
1127
Mark Dickinsonb6467572008-08-04 21:30:09 +00001128- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1129 ValueError consistently across platforms.
1130
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001131- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1132 (64bit Unix, for example), unichr() would truncate its argument and return
1133 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1134
Neal Norwitze7d8be82008-07-31 17:17:14 +00001135- Apply security patches from Apple.
1136
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001137- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1138 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1139
Antoine Pitrou92f82162008-07-25 22:22:08 +00001140- Issue #1819: function calls with several named parameters are now on
1141 average 35% faster (as measured by pybench).
1142
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001143- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1144 the python debugger steps into a class statement: the free variables (local
1145 variables defined in an outer scope) would be deleted from the outer scope.
1146
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001147- Issue #2620: Overflow checking when allocating or reallocating memory
1148 was not always being done properly in some python types and extension
1149 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1150 all been updated to perform better checks and places in the code that
1151 would previously leak memory on the error path when such an allocation
1152 failed have been fixed.

1161
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001162- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1163 version reported by these tools does not necessarily follow the python
1164 version numbering scheme, so the module is less strict when parsing it.
1165
Nick Coghlanf70385a2008-08-18 12:42:46 +00001166- Issue #2235: Added Py3k warnings for types which will become unhashable
1167 under the stricter __hash__ inheritance rules in 3.0. Several types
1168 which did not meet the rules for hash invariants and were already
1169 unhashable in 3.0 have now been explicitly flagged as unhashable in
1170 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1171 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1172
Brett Cannon88f801d2008-08-18 00:46:22 +00001173- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1202 thread-safe.
1203
Brett Cannonbf3157b2008-08-14 05:00:03 +00001204- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1205 since mimetools itself is deprecated. Because modules are cached, all
1206 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1207
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001208- Issue #3134: shutil referenced undefined WindowsError symbol.

1220 to _sre.compile() will now be rejected. This should not affect anybody
1221 since the re.compile() function never generates invalid re-bytecode.
1222
Skip Montanaroa032bf42008-08-08 22:52:51 +00001223- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1224 upon first access it can be automatically initialized from the csv file if
1225 it wasn't initialized during instantiation.
1226
Brett Cannon3aa2a492008-08-06 22:28:09 +00001227- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1228 the reload() built-in has been removed.
1229
Brett Cannon7e30b672008-08-04 21:52:25 +00001230- Changed code in the following modules/packages to remove warnings raised

1239 raised an AttributeError.
1240
Benjamin Peterson01a24322008-07-28 23:35:27 +00001241- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001242 asking for a specific length. This problem only affected files opened
1243 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001244

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001268- Issue #3394: zipfile.writestr sets external attributes when passed a
1269 file name rather than a ZipInfo instance, so files are extracted with
1270 mode 0600 rather than 000 under Unix.
1271
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001272- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001284- Issue #2235: the C API function PyObject_HashNotImplemented and its
1285 interaction with the tp_hash slot (added in 2.6b2) are now documented
1286
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001287- Issue #643841: The language reference now provides more detailed
1288 coverage of the lookup process for special methods. The disclaimers
1289 regarding lack of coverage of new-style classes have also been
1290 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001293What's New in Python 2.6 beta 2?
1294================================
1295
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001296*Release date: 17-Jul-2008*
1297
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001298Core and Builtins
1299-----------------
1300
Georg Brandl3e483f62008-07-16 22:57:41 +00001301- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1302 its methods now allow for items objects that can be converted to
1303 an integer using operator.index().
1304
Mark Dickinson64b7e502008-07-16 09:40:03 +00001305- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1306 produced a ValueError instead of giving the correct float.
1307
Eric Smitha5fa5a22008-07-16 00:11:49 +00001308- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1309 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1310
Mark Dickinson7103aa42008-07-15 19:08:33 +00001311- Issue #3008: the float type has a new instance method 'float.hex'
1312 and a new class method 'float.fromhex' to convert floating-point
1313 numbers to and from hexadecimal strings, respectively.
1314
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001315- Issue #2235: __hash__ is once again inherited by default. To allow
1316 collections.Hashable to remain meaningful in the presence of the
1317 default hash implementation (object.__hash__), it is now possible
1318 to explicit block inheritance of hash by setting __hash__=None at
1319 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1320 level.
1321
Nick Coghlanb028f502008-07-13 14:52:36 +00001322- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1323 the parent module cannot be found while performing an absolute import.
1324 This means that an incorrectly defined __package__ attribute will
1325 now only prevent relative imports in that module rather than causing
1326 all imports from that module to fail.
1327
Nick Coghlan14ff9942008-07-08 14:21:42 +00001328- Issue #2517: Allow unicode messages in Exceptions again by correctly
1329 bypassing the instance dictionary when looking up __unicode__ on
1330 new-style classes.
1331
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001332- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1333 set to a custom object whose write() method happens to install
1334 another file in sys.stdout.
1335
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001336- Issue #3088: Corrected a race condition in classes derived from
1337 threading.local: the first member set by a thread could be saved in
1338 another thread's dictionary.
1339
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001340- Issue #3004: Minor change to slice.indices(): the start and stop
1341 arguments are now treated identically, making the behaviour easier
1342 to describe and understand. For example, slice(None, -10,
1343 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1344 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1345 10, -1).
1346
Georg Brandl278fc502008-07-19 12:46:12 +00001347- Issue #3219: Calling a function with repeated keyword arguments,
1348 f(a=2, a=23), would not cause a syntax error. This was a regression
1349 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001350
Georg Brandl278fc502008-07-19 12:46:12 +00001351- Issue #2862: Make int and float freelist management consistent with
1352 other freelists. Changes their CompactFreeList apis into
1353 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001354

1356-------
1357
Thomas Heller57adf222008-08-14 19:10:48 +00001358- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1359 api functions without holding the GIL, which could lead to a fatal
1360 error when they failed.
1361
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001362- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1371 ForkingPickler.register() to resolve conflict with ctypes.
1372
Vinay Sajip51e65192008-07-18 09:01:10 +00001373- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00001375- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1376 a valid dlerror() message.
1377
Thomas Heller2bad6572008-07-15 17:19:50 +00001378- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1379 incomplete structure was created.
1380

1384
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001385- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001386
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001387- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1388 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001389 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001390 content-length. The problem had been corrected in the 2.4 branch, but never
1391 merged into trunk.
1392
Georg Brandle78fbcc2008-07-05 10:13:36 +00001393- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001406- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1407 handling is now the same as that of other special attributes like __name__).
1408
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001409- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1410 removal in Python 3.0 in favor of urllib2.urlopen().

1421 default https port (443).
1422
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00001423- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl5cc774e2008-06-11 20:28:06 +00001799 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001800
1801 This is controlled by the configure argument ``--with-universal-archs``:
1802
1803 - ``--with-universal-archs=all``: install 4-way universal
1804
1805 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1806
1807 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1808
1809 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001861- Issue #1631171: Re-implement the 'warnings' module in C (the
1862 original Python code has been kept as backup). This will allow for
1863 using the 'warning's machinery in such places as the parser where
1864 use of pure Python code is not possible. Both the ``showarning()``
1865 and ``formatwarning()`` gain an optional 'line' argument which is
1866 not called by default for backwards-compatibility reasons. Setting
1867 ``warnings.showwarning()`` to an implementation that lacks support
1868 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001931- Issue #2550: The approach used by client/server code for obtaining
1932 ports to listen on in network-oriented tests has been refined in an
1933 effort to facilitate running multiple instances of the entire
1934 regression test suite in parallel without issue.
1935 test_support.bind_port() has been fixed such that it will always
1936 return a unique port -- which wasn't always the case with the
1937 previous implementation, especially if socket options had been set
1938 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1939 new implementation of bind_port() will actually raise an exception
1940 if it is passed an AF_INET/SOCK_STREAM socket with either the
1941 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1942 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1943 the socket it's been passed. This currently only applies to
1944 Windows. This option prevents any other sockets from binding to the
1945 host/port we've bound to, thus removing the possibility of the
1946 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1947 when a second SOCK_STREAM socket binds and accepts to a host/port
1948 that's already been bound by another socket. The optional preferred
1949 port parameter to bind_port() has been removed. Under no
1950 circumstances should tests be hard coding ports!
1951
1952 test_support.find_unused_port() has also been introduced, which will
1953 pass a temporary socket object to bind_port() in order to obtain an
1954 unused port. The temporary socket object is then closed and
1955 deleted, and the port is returned. This method should only be used
1956 for obtaining an unused port in order to pass to an external program
1957 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1958 a parameter to a server-oriented class that doesn't give you direct
1959 access to the underlying socket used.
1960
1961 Finally, test_support.HOST has been introduced, which should be used
1962 for the host argument of any relevant socket calls (i.e. bind and
1963 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001964
1965 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001966 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001967 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1968 test_asynchat and test_socket_ssl.
1969
Georg Brandl3ee81df2008-05-17 18:14:43 +00001970 It is now possible for multiple instances of the regression test
1971 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002025- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002026 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2027 Plane. This affected raw unicode literals and the
2028 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2029 this case, like normal unicode literals and the 'unicode-escape'
2030 codec.

2249
Eric Smitha73fbe72008-02-23 03:09:44 +00002250- Added the future_builtins module, which contains hex() and oct().
2251 These are the PEP 3127 version of these functions, designed to be
2252 compatible with the hex() and oct() builtins from Python 3.0. They
2253 differ slightly in their output formats from the existing, unchanged
2254 Python 2.6 builtins. The expected usage of the future_builtins
2255 module is:

2257
Eric Smith7ef40bf2008-02-20 23:34:22 +00002258- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2259 exponents for exponents with absolute value < 100. Follows C99
2260 standard. This is a change on Windows, which would use 3 digits.
2261 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2262 so that any alterations it does to the resulting string will be
2263 available in stringlib/formatter.h (for float.__format__).
2264
Eric Smith5a3c1352008-02-19 13:21:56 +00002265- Implemented PEP 3101, Advanced String Formatting. This adds a new
2266 builtin format(); a format() method for str and unicode; a
2267 __format__() method to object, str, unicode, int, long, float, and
2268 datetime; the class string.Formatter; and the C API
2269 PyObject_Format().
2270
Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Fixed several potential crashes, all caused by specially crafted
2272 __del__ methods exploiting objects in temporarily inconsistent
2273 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002274
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002275- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002276 prevent a possible crash: an Abstract Base Class would try to access
2277 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002278

Georg Brandl3ee81df2008-05-17 18:14:43 +00002282- Clear all free lists during a gc.collect() of the highest generation
2283 in order to allow pymalloc to free more arenas. Python may give back
2284 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002285
Georg Brandl3ee81df2008-05-17 18:14:43 +00002286- Issue #2045: Fix an infinite recursion triggered when printing a
2287 subclass of collections.defaultdict, if its default_factory is set
2288 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00002290- Fixed a minor memory leak in dictobject.c. The content of the free
2291 list was not freed on interpreter shutdown.
2292
Georg Brandl3ee81df2008-05-17 18:14:43 +00002293- Limit free list of method and builtin function objects to 256
2294 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002295
Georg Brandl3ee81df2008-05-17 18:14:43 +00002296- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2297 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002298 to compact the internal free lists of pre-allocted ints and floats.
2299

Georg Brandl3ee81df2008-05-17 18:14:43 +00002316- Patch #1473257: generator objects gain a gi_code attribute. This is
2317 the same object as the func_code attribute of the function that
2318 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002319
Georg Brandl3ee81df2008-05-17 18:14:43 +00002320- Issue #1920: "while 0" statements were completely removed by the
2321 compiler, even in the presence of an "else" clause, which is
2322 supposed to be run when the condition is false. Now the compiler
2323 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002324
Guido van Rossumeead05f2008-01-24 18:21:02 +00002325- A few crashers fixed: weakref_in_del.py (issue #1377858);
2326 loosing_dict_ref.py (issue #1303614, test67.py);
2327 borrowed_ref_[34].py (not in tracker).
2328
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002329- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002330 suppressed while an extension is loaded by calling SetErrorMode in
2331 dynload_win.c. The error is still reported properly.
2332
Georg Brandl3ee81df2008-05-17 18:14:43 +00002333- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002334 several extension methods and modules do not work without unicode
2335 support.
2336
Georg Brandl26543b12008-01-21 18:36:51 +00002337- Issue #1882: when compiling code from a string, encoding cookies in the
2338 second line of code were not always recognized correctly.
2339
Georg Brandl14404b62008-01-19 19:27:05 +00002340- Issue #1679: "0x" was taken as a valid integer literal.
2341
Georg Brandl6caad7d2008-01-26 14:19:22 +00002342- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002343 added.
2344
Christian Heimesc94e2b52008-01-14 04:13:37 +00002345- sys.float_info / PyFloat_GetInfo: The floating point information
2346 object was converted from a dict to a specialized structseq object.
2347
Georg Brandl3ee81df2008-05-17 18:14:43 +00002348- Patch #1816: Added sys.flags structseq. It exposes the status of
2349 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002350
Georg Brandl3ee81df2008-05-17 18:14:43 +00002351- Objects/structseq.c: Implemented new structseq representation. The
2352 patch makes structseqs (e.g. the return value of os.stat) more
2353 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002354
Georg Brandl3ee81df2008-05-17 18:14:43 +00002355- Patch #1700288: added a type attribute cache that caches method
2356 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002357
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002358- Bug #1776: __import__() no longer accepts filenames on any platform.
2359 The first parameter to __import__() must be a valid module name.

2364 envvar and sys.dont_write_bytecode attribute. All these can be set
2365 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002366
Georg Brandl3ee81df2008-05-17 18:14:43 +00002367- Improve some exception messages when Windows fails to load an
2368 extension module. Now we get for example '%1 is not a valid Win32
2369 application' instead of 'error code 193'.

2426
Georg Brandl3ee81df2008-05-17 18:14:43 +00002427- The enumerate() builtin function is no longer bounded to sequences
2428 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2429 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002430
Georg Brandl3ee81df2008-05-17 18:14:43 +00002431- Issue #1686386: Tuple's tp_repr did not take into account the
2432 possibility of having a self-referential tuple, which is possible
2433 from C code. Nor did object's tp_str consider that a type's tp_str
2434 could do something that could lead to an inifinite recursion.
2435 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2436 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002437
Georg Brandl3ee81df2008-05-17 18:14:43 +00002438- Issue #1164: It was possible to trigger deadlock when using the
2439 'print' statement to write to a file since the GIL was not released
2440 as needed. Now PyObject_Print() does the right thing along with
2441 various tp_print implementations of the built-in types and those in
2442 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002443

Georg Brandl3ee81df2008-05-17 18:14:43 +00002452 PyObject_Call() never calling back out to Python code to trigger
2453 recursion depth updates/checks. Required the creation of a static
2454 RuntimeError instance in case normalizing an exception put the
2455 recursion check value past its limit. Fixes crashers

2503
Guido van Rossum143b5642007-03-23 04:58:42 +00002504- Bug #1683368: The object.__init__() and object.__new__() methods are
2505 now stricter in rejecting excess arguments. The only time when
2506 either allows excess arguments is when it is not overridden and the
2507 other one is. For backwards compatibility, when both are
2508 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002509 warning later). Also, type.__init__() insists on the same signature
2510 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002512- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2513 object to complex using its __complex__() method before falling back
2514 to the __float__() method. Therefore, the functions in the cmath
2515 module now can operate on objects that define a __complex__()
2516 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00002534- Bug #1678647: write a newline after printing an exception in any
2535 case, even when converting the value to a string failed.
2536
Georg Brandl871f1bc2007-03-12 13:17:36 +00002537- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002538 its argument, if it exists. If not, it will work like before. This
2539 allows customizing the output of dir() in the presence of a
2540 __getattr__().

2550 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00002552- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002553 makes the filenames the warning module prints much more sensible
2554 when a PYTHONSTARTUP file is used.

2568 sq_ass_slice instead of the sq_slice slot.
2569
Georg Brandl3ee81df2008-05-17 18:14:43 +00002570- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00002622- Bug #1545497: when given an explicit base, int() did ignore NULs
2623 embedded in the string to convert.
2624
Georg Brandl846f73a2006-10-08 07:11:54 +00002625- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00002673 generator expressions (x for x, in ... ) works again. Fixing this
2674 problem required changing the .pyc magic number. This means that
2675 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003105 AttributeError instead of an IOError when the server's response

3197 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00003478- The implementation of UnicodeError objects has been simplified
3479 (start and end attributes are now stored directly as Py_ssize_t
3480 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00003481
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3483 with RFC 3207 and forgets any knowledge obtained from the server not
3484 obtained from the TLS negotiation itself. Patch contributed by Bill
3485 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003486
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003488 that the SMTP.starttls() caller no longer needs to call ehlo()
3489 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003490 does not claim to support starttls. Adds the
3491 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3492 Fenner.

3572 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3573 silently miscode subclasses of those types. Now, it raises a
3574 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003575

Georg Brandl3ee81df2008-05-17 18:14:43 +00003590 time so that opening a database previously created with the DB_DUP
3591 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3592 opens. Specifically: dictionary assignment to a DB object will
3593 replace all values for a given key when the database allows
3594 duplicate values. DB users should use DB.put(k, v) when they want
3595 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003596

3602 characters with ASCII value less than 32. Also, it correctly quotes
3603 dots only if they occur on a single line, as opposed to the previous
3604 behavior of quoting dots if they are the second character of any
3605 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003606
