11
12Core and Builtins
13-----------------
14
Eric Smitha985a3a2009-05-05 18:26:08 +000015- Issue #5920: For float.__format__, change the behavior with the
16 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
17 to be like 'g' but with at least one decimal point and with a
18 default precision of 12. Previously, the behavior the same but with
19 a default precision of 6. This more closely matches str(), and
20 reduces surprises when adding alignment flags to the empty
21 presentation type. This also affects the new complex.__format__ in
22 the same way.
23
R. David Murray7ba8e1c2009-05-04 22:16:24 +000024- Issue #5890: in subclasses of 'property' the __doc__ attribute was
25 shadowed by classtype's, even if it was None. property now
26 inserts the __doc__ into the subclass instance __dict__.
27
Antoine Pitrou653dece2009-05-04 18:32:32 +000028- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
29 sequences. Patch by Nick Barnes and Victor Stinner.
30
Eric Smith9139cc62009-04-30 00:58:58 +000031- Issue #1588: Add complex.__format__. For example,
32 format(complex(1, 2./3), '.5') now produces a sensible result.
33
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000034- Issue #5864: Fix empty format code formatting for floats so that it
35 never gives more than the requested number of significant digits.
36
Eric Smithcac7af62009-04-27 19:04:37 +000037- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
38 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
39
Martin v. Löwis99f27792009-04-26 00:53:18 +000040- Issue #4971: Fix titlecase for characters that are their own
41 titlecase, but not their own uppercase.
42
Eric Smith068f0652009-04-25 21:40:15 +000043- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
44 _PyOS_double_to_string or PyOS_double_to_string.
45
Benjamin Peterson5083dc52009-04-25 00:41:22 +000046- Issue #5283: Setting __class__ in __del__ caused a segfault.
47
Mark Dickinson95bc9802009-04-24 12:46:53 +000048- Issue #5816: complex(repr(z)) now recovers z exactly, even when
49 z involves nans, infs or negative zeros.
50
Eric Smithaca19e62009-04-22 13:29:05 +000051- Implement PEP 378, Format Specifier for Thousands Separator, for
52 floats, ints, and longs.
53
54- Issue #5515: 'n' formatting for ints, longs, and floats handles
55 leading zero formatting poorly.
56
57- Issue #5772: For float.__format__, don't add a trailing ".0" if
58 we're using no type code and we have an exponent.
59
Mark Dickinson6736cf82009-04-20 21:13:33 +000060- Issue #3166: Make long -> float (and int -> float) conversions
61 correctly rounded.
62
Benjamin Petersond4d400c2009-04-18 20:12:47 +000063- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
64 some builtin types.
65
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000066- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +000067 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000068
Benjamin Peterson99d36f12009-04-15 21:26:36 +000069- Issue #5759: float() didn't call __float__ on str subclasses.
70
Georg Brandl3c4a5462009-04-12 12:08:12 +000071- Issue #5704: the "-3" command-line option now implies "-t".
72
R. David Murray0374a822009-04-09 21:54:50 +000073- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
74 its clarity and its speed.
75
Antoine Pitrou789be0c2009-04-02 21:18:34 +000076- Issue #2396: the memoryview object was backported from Python 3.1.
77
Georg Brandld3f03fa2009-04-02 18:09:04 +000078- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
79 when hitting the recursion limit under certain circumstances.
80
Brett Cannon15ba4da2009-04-01 18:03:59 +000081- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
82
Ronald Oussorene0154ed2009-03-30 23:10:35 +000083- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
84 the end sys.path, for compatibility with the system install of Python.
85
Antoine Pitrouf8387af2009-03-23 18:41:45 +000086- Issue #4688: Add a heuristic so that tuples and dicts containing only
87 untrackable objects are not tracked by the garbage collector. This can
88 reduce the size of collections and therefore the garbage collection overhead
89 on long-running programs, depending on their particular use of datatypes.
90
Mark Dickinson0b666bf2009-03-23 18:25:13 +000091- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
92 improve its performance. Long divisions and remainder operations
93 are now between 50% and 150% faster.
94
Mark Dickinsonefc82f72009-03-20 15:51:55 +000095- Issue #4258: Make it possible to use base 2**30 instead of base
96 2**15 for the internal representation of integers, for performance
97 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
98 --enable-big-digits option to configure, which overrides the
99 default. Add sys.long_info structseq to provide information about
100 the internal format.
101
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000102- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
103 result traceback.__members__ no longer exists.)
104
Mark Dickinson6b265f12009-03-18 16:07:26 +0000105- Issue #4474: PyUnicode_FromWideChar now converts characters outside
106 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
107 and sizeof(Py_UNICODE) == 2.
108
Eric Smith6f42edb2009-03-14 11:57:26 +0000109- Issue #5237: Allow auto-numbered fields in str.format(). For
110 example: '{} {}'.format(1, 2) == '1 2'.
111
Brett Cannon6c4cff02009-03-11 04:51:06 +0000112- Issue #3652: Make the 'line' argument for warnings.showwarning() a
113 requirement. Means the DeprecationWarning from Python 2.6 can go away.
114
Eric Smithe9fb6862009-02-20 14:02:36 +0000115- Issue #5247: Improve error message when unknown format codes are
116 used when using str.format() with str, unicode, long, int, and
117 float arguments.
118
Raymond Hettinger08259e82009-02-18 23:10:19 +0000119- Running Python with the -3 option now also warns about classic division
120 for ints and longs.
121
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000122- Issue #5260: Long integers now consume less memory: average
123 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
124 on a 64-bit system.
125
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000126- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
127 rotating the object pointer by 4 bits to the right.
128
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000129- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
130 it now forces its argument to double before testing for infinity.
131
Benjamin Petersone18ef192009-01-20 14:21:16 +0000132- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
133
Georg Brandl29c6a282009-04-05 20:23:13 +0000134- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000135 were suppressing all exceptions. These include list(), filter(), map(),
136 zip(), and bytearray().
137
Benjamin Peterson596d3062009-01-19 15:42:23 +0000138- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
139 functions.
140
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000141- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
142 OSError.
143

145
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000146- Issue #4935: The overflow checking code in the expandtabs() method common
147 to str, bytes and bytearray could be optimized away by the compiler, letting
148 the interpreter segfault instead of raising an error.
149
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000150- Issue #3720: Fix a crash when an iterator modifies its class and removes its
151 __next__ method.
152

156
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000157- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
158 collecting the oldest generation) so that allocating lots of objects without
159 destroying them does not show quadratic performance. Based on a proposal by
160 Martin von Löwis at
161 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
162
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000163- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
164
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000165- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
166 an existing .py counterpart, override the co_filename attributes of all
167 code objects if the original filename is obsolete (which can happen if the
168 file has been renamed, moved, or if it is accessed through different paths).
169 Patch by Ziga Seilnacht and Jean-Paul Calderone.
170
Martin v. Löwis5344c992009-01-02 20:32:55 +0000171- Issue #4075: Use OutputDebugStringW in Py_FatalError.
172
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000173- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
174 file with `str' filename on Windows.
175
Antoine Pitrouaa687902009-01-01 14:11:22 +0000176- Issue #3680: Reference cycles created through a dict, set or deque iterator
177 did not get collected.
178
Nick Coghlan180e4002008-12-30 01:18:48 +0000179- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
180 where the tp_hash and tp_dict slots are both NULL.
181
Benjamin Peterson7af65562008-12-29 17:56:58 +0000182- Issue #4764: With io.open, IOError.filename is set when trying to open a
183 directory on POSIX systems.
184
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000185- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
186 systems.
187
Georg Brandl6425a2f2008-12-28 11:54:53 +0000188- Issue #4759: None is now allowed as the first argument of
189 bytearray.translate(). It was always allowed for bytes.translate().
190
Skip Montanarof205c132008-12-23 03:30:15 +0000191- Added test case to ensure attempts to read from a file opened for writing
192 fail.
193
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000194- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
195 print elapsed times, not only when some objects are uncollectable /
196 unreachable. Original patch by Neil Schemenauer.
197
Mark Dickinson1a707982008-12-17 16:14:37 +0000198- Issue #3439: Add a bit_length method to int and long.

202
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000203- Issue #4597: Fixed exception handling when the __exit__ function of a
204 context manager returns a value that cannot be converted to a bool.
205
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000206- Issue #4597: Fixed several opcodes that weren't always propagating
207 exceptions.
208
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000209- Issue #4445: Replace "sizeof(PyStringObject)" with
210 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
211 str instances. On a typical machine this saves 3 bytes of memory
212 (on average) per string allocation.
213
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000214- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
215 interpreter to abort ("Fatal Python error: Could not reset the stack!")

223
Vinay Sajip213faca2008-12-03 23:22:58 +0000224- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000225 method on file objects with closefd=False. The file descriptor is still
226 kept open but the file object behaves like a closed file. The ``FileIO``
227 object also got a new readonly attribute ``closefd``.
228
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000229- Issue #4348: Some bytearray methods returned that didn't cause any change to
230 the bytearray, returned the same bytearray instead of a copy.
231
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000232- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

239 exec statement.
240
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000241- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
242 method does not return iterators for the 4th and 5th items.
243
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000244- Issue #4209: Enabling unicode_literals and the print_function in the same
245 __future__ import didn't work.
246
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000247- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000248 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000249
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000250- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
251 returned a path longer than MAX_PATH. (But It's doubtful this code path is
252 really executed because I cannot move to such directory on win2k)
253
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000254- Issue #4069: When set.remove(element) is used with a set element, the element
255 is temporarily replaced with an equivalent frozenset. But the eventual
256 KeyError would always report the empty frozenset([]) as the missing key. Now
257 it correctly refers to the initial element.
258
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000259- Issue #4509: Various issues surrounding resize of bytearray objects to
260 which there are buffer exports.

275 returned them on 64bit platforms.
276
Walter Dörwalded960ac2009-05-03 22:36:33 +0000277- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
278 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
279 step. This avoids problems with counting UTF-8 bytes that ignores the effect
280 of using the replace error handler in PyUnicode_DecodeUTF8().
281
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000282- Issue #3739: The unicode-internal encoder now reports the number of characters
283 consumed like any other encoder (instead of the number of bytes).

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001084- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

1086 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1087 ``printf`` function, whereas PyString_FromFormat has an independent
1088 implementation and uses "%zd" on all platforms for size_t values.

1185 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1186 for catch_warnings() also led to an improvement in the raising of a
1187 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001253What's New in Python 2.6 beta 3?
1254================================
1255
Barry Warsaw07a4a382008-08-21 01:15:08 +00001256*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001257
1258Core and Builtins
1259-----------------
1260
Guido van Rossumf8402962008-08-20 15:01:50 +00001261- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1262 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1263 extensions do not automatically benefit from the class attribute
1264 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1265 to their tp_flags field if they care. This is a backwards
1266 compatibility feature; in 3.0, all types will use the cache by
1267 default.
1268
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001269- Keyword arguments can now follow starred arguments. (``f(a, *args,
1270 keyword=23)`` is now valid syntax.)
1271
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001272- ctypes function pointers that are COM methods have a boolean True
1273 value again.
1274
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001275- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1276 by denying s# to parse objects that have a releasebuffer procedure,
1277 and introducing s*.
1278
Georg Brandl1e13ea92008-08-11 09:07:59 +00001279- Issue #3537: Fix an assertion failure when an empty but presized dict
1280 object was stored in the freelist.
1281
Mark Dickinsonb6467572008-08-04 21:30:09 +00001282- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1283 ValueError consistently across platforms.
1284
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001285- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1286 (64bit Unix, for example), unichr() would truncate its argument and return
1287 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1288
Neal Norwitze7d8be82008-07-31 17:17:14 +00001289- Apply security patches from Apple.
1290
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001291- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1292 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1293
Antoine Pitrou92f82162008-07-25 22:22:08 +00001294- Issue #1819: function calls with several named parameters are now on
1295 average 35% faster (as measured by pybench).
1296
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001297- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1298 the python debugger steps into a class statement: the free variables (local
1299 variables defined in an outer scope) would be deleted from the outer scope.
1300
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001301- Issue #2620: Overflow checking when allocating or reallocating memory
1302 was not always being done properly in some python types and extension
1303 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1304 all been updated to perform better checks and places in the code that
1305 would previously leak memory on the error path when such an allocation
1306 failed have been fixed.
1307
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001308Library
1309-------
1310
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001311- Issue #3612: Added some missing basic types in ctypes.wintypes.
1312
Benjamin Petersone977ad42008-08-20 01:42:01 +00001313- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1314 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1315
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001316- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1317 version reported by these tools does not necessarily follow the python
1318 version numbering scheme, so the module is less strict when parsing it.
1319
Nick Coghlanf70385a2008-08-18 12:42:46 +00001320- Issue #2235: Added Py3k warnings for types which will become unhashable
1321 under the stricter __hash__ inheritance rules in 3.0. Several types
1322 which did not meet the rules for hash invariants and were already
1323 unhashable in 3.0 have now been explicitly flagged as unhashable in
1324 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1325 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1326
Brett Cannon88f801d2008-08-18 00:46:22 +00001327- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1331
Brett Cannon46225e72008-08-18 00:36:52 +00001332- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

1335
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001336- Issue #3575: Incremental decoder's decode function now takes bytearray
1337 by using 's*' instead of 't#'.
1338
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001339- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001340 fails unicode conversion on 2nd parameter. (windows only)
1341
Facundo Batista94f243a2008-08-17 03:38:39 +00001342- Issue 2464. urllib2 now supports a malformation in the URL received
1343 in a redirect.
1344
Brett Cannonabe423e2008-08-16 21:47:07 +00001345- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001346 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001347
Facundo Batistaeb90b782008-08-16 14:44:07 +00001348- Issue #2776: fixed small issue when handling an URL with double slash
1349 after a 302 response in the case of not going through a proxy.
1350
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001351- Issue #2676: in the email package, content-type parsing was hanging on
1352 pathological input because of quadratic or exponential behaviour of a
1353 regular expression.
1354
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001355- Issue #3476: binary buffered reading through the new "io" library is now
1356 thread-safe.
1357
Brett Cannonbf3157b2008-08-14 05:00:03 +00001358- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1359 since mimetools itself is deprecated. Because modules are cached, all
1360 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1361
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001362- Issue #3134: shutil referenced undefined WindowsError symbol.
1363
Robert Schuppenies14646332008-08-10 11:01:53 +00001364- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1365 menu entries were not deleted.
1366
Brett Cannon83e81842008-08-09 23:30:55 +00001367- Copied the implementation of reduce() to _functools.reduce() to have a
1368 version that did not raise a DeprecationWarning under -3.
1369
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001370- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1371 a MemoryError rather than silently stop the iteration.
1372
Guido van Rossum59ce9012008-08-09 14:55:34 +00001373- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1374 to _sre.compile() will now be rejected. This should not affect anybody
1375 since the re.compile() function never generates invalid re-bytecode.
1376
Skip Montanaroa032bf42008-08-08 22:52:51 +00001377- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00001396 asking for a specific length. This problem only affected files opened
1397 using the new "io" module, not the built-in open() function.

1424 mode 0600 rather than 000 under Unix.
1425
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001426- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1460 produced a ValueError instead of giving the correct float.
1461
Eric Smitha5fa5a22008-07-16 00:11:49 +00001462- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Mark Dickinson7103aa42008-07-15 19:08:33 +00001465- Issue #3008: the float type has a new instance method 'float.hex'
1466 and a new class method 'float.fromhex' to convert floating-point
1467 numbers to and from hexadecimal strings, respectively.
1468
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001469- Issue #2235: __hash__ is once again inherited by default. To allow
1470 collections.Hashable to remain meaningful in the presence of the
1471 default hash implementation (object.__hash__), it is now possible
1472 to explicit block inheritance of hash by setting __hash__=None at
1473 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1474 level.
1475
Nick Coghlanb028f502008-07-13 14:52:36 +00001476- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1477 the parent module cannot be found while performing an absolute import.
1478 This means that an incorrectly defined __package__ attribute will
1479 now only prevent relative imports in that module rather than causing
1480 all imports from that module to fail.

1493
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001494- Issue #3004: Minor change to slice.indices(): the start and stop
1495 arguments are now treated identically, making the behaviour easier
1496 to describe and understand. For example, slice(None, -10,
1497 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1498 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1499 10, -1).

1542 both unnecessary (HTTP allows text content to be sent in several forms) and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002015- Issue #1631171: Re-implement the 'warnings' module in C (the
2016 original Python code has been kept as backup). This will allow for
2017 using the 'warning's machinery in such places as the parser where
2018 use of pure Python code is not possible. Both the ``showarning()``
2019 and ``formatwarning()`` gain an optional 'line' argument which is
2020 not called by default for backwards-compatibility reasons. Setting
2021 ``warnings.showwarning()`` to an implementation that lacks support
2022 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002085- Issue #2550: The approach used by client/server code for obtaining
2086 ports to listen on in network-oriented tests has been refined in an
2087 effort to facilitate running multiple instances of the entire
2088 regression test suite in parallel without issue.
2089 test_support.bind_port() has been fixed such that it will always
2090 return a unique port -- which wasn't always the case with the
2091 previous implementation, especially if socket options had been set
2092 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2093 new implementation of bind_port() will actually raise an exception
2094 if it is passed an AF_INET/SOCK_STREAM socket with either the
2095 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2096 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2097 the socket it's been passed. This currently only applies to
2098 Windows. This option prevents any other sockets from binding to the
2099 host/port we've bound to, thus removing the possibility of the
2100 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2101 when a second SOCK_STREAM socket binds and accepts to a host/port
2102 that's already been bound by another socket. The optional preferred
2103 port parameter to bind_port() has been removed. Under no
2104 circumstances should tests be hard coding ports!
2105
2106 test_support.find_unused_port() has also been introduced, which will
2107 pass a temporary socket object to bind_port() in order to obtain an
2108 unused port. The temporary socket object is then closed and
2109 deleted, and the port is returned. This method should only be used
2110 for obtaining an unused port in order to pass to an external program
2111 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2112 a parameter to a server-oriented class that doesn't give you direct
2113 access to the underlying socket used.
2114
2115 Finally, test_support.HOST has been introduced, which should be used
2116 for the host argument of any relevant socket calls (i.e. bind and
2117 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002118
2119 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002120 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002121 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2122 test_asynchat and test_socket_ssl.
2123
Georg Brandl3ee81df2008-05-17 18:14:43 +00002124 It is now possible for multiple instances of the regression test
2125 suite to run in parallel without issue.

2392-----------------
2393
Fred Drakea8ee94b2008-03-01 02:45:07 +00002394- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002395 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002396
Georg Brandlad61bc82008-02-23 15:11:18 +00002397- Issue #2067: file.__exit__() now calls subclasses' close() method.
2398
2399- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002400
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002401- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002402 issue 215555 for a discussion.
2403
Eric Smitha73fbe72008-02-23 03:09:44 +00002404- Added the future_builtins module, which contains hex() and oct().
2405 These are the PEP 3127 version of these functions, designed to be
2406 compatible with the hex() and oct() builtins from Python 3.0. They
2407 differ slightly in their output formats from the existing, unchanged
2408 Python 2.6 builtins. The expected usage of the future_builtins
2409 module is:
2410 from future_builtins import hex, oct
2411
Eric Smith7ef40bf2008-02-20 23:34:22 +00002412- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2413 exponents for exponents with absolute value < 100. Follows C99
2414 standard. This is a change on Windows, which would use 3 digits.
2415 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2416 so that any alterations it does to the resulting string will be
2417 available in stringlib/formatter.h (for float.__format__).
2418
Eric Smith5a3c1352008-02-19 13:21:56 +00002419- Implemented PEP 3101, Advanced String Formatting. This adds a new
2420 builtin format(); a format() method for str and unicode; a
2421 __format__() method to object, str, unicode, int, long, float, and
2422 datetime; the class string.Formatter; and the C API
2423 PyObject_Format().
2424
Georg Brandl3ee81df2008-05-17 18:14:43 +00002425- Fixed several potential crashes, all caused by specially crafted
2426 __del__ methods exploiting objects in temporarily inconsistent
2427 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002428
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002429- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002430 prevent a possible crash: an Abstract Base Class would try to access
2431 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002432
Georg Brandl3ee81df2008-05-17 18:14:43 +00002433- Fixed repr() and str() of complex numbers with infinity or nan as
2434 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002435
Georg Brandl3ee81df2008-05-17 18:14:43 +00002436- Clear all free lists during a gc.collect() of the highest generation
2437 in order to allow pymalloc to free more arenas. Python may give back
2438 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002439
Georg Brandl3ee81df2008-05-17 18:14:43 +00002440- Issue #2045: Fix an infinite recursion triggered when printing a
2441 subclass of collections.defaultdict, if its default_factory is set
2442 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002443
Christian Heimesf75dbef2008-02-08 00:11:31 +00002444- Fixed a minor memory leak in dictobject.c. The content of the free
2445 list was not freed on interpreter shutdown.
2446
Georg Brandl3ee81df2008-05-17 18:14:43 +00002447- Limit free list of method and builtin function objects to 256
2448 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002449
Georg Brandl3ee81df2008-05-17 18:14:43 +00002450- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2451 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002452 to compact the internal free lists of pre-allocted ints and floats.
2453
Georg Brandl3ee81df2008-05-17 18:14:43 +00002454- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2455 calls. Python expected the return type int but the fork familie
2456 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002457
Georg Brandl3ee81df2008-05-17 18:14:43 +00002458- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2459 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002460
Georg Brandl3ee81df2008-05-17 18:14:43 +00002461- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2462 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002463
Georg Brandl3ee81df2008-05-17 18:14:43 +00002464- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2465 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002466
Georg Brandl3ee81df2008-05-17 18:14:43 +00002467- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2468 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002469
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470- Patch #1473257: generator objects gain a gi_code attribute. This is
2471 the same object as the func_code attribute of the function that
2472 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002473
Georg Brandl3ee81df2008-05-17 18:14:43 +00002474- Issue #1920: "while 0" statements were completely removed by the
2475 compiler, even in the presence of an "else" clause, which is
2476 supposed to be run when the condition is false. Now the compiler
2477 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002478
Guido van Rossumeead05f2008-01-24 18:21:02 +00002479- A few crashers fixed: weakref_in_del.py (issue #1377858);
2480 loosing_dict_ref.py (issue #1303614, test67.py);
2481 borrowed_ref_[34].py (not in tracker).
2482
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002483- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002484 suppressed while an extension is loaded by calling SetErrorMode in
2485 dynload_win.c. The error is still reported properly.
2486
Georg Brandl3ee81df2008-05-17 18:14:43 +00002487- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002488 several extension methods and modules do not work without unicode
2489 support.
2490
Georg Brandl26543b12008-01-21 18:36:51 +00002491- Issue #1882: when compiling code from a string, encoding cookies in the
2492 second line of code were not always recognized correctly.
2493
Georg Brandl14404b62008-01-19 19:27:05 +00002494- Issue #1679: "0x" was taken as a valid integer literal.
2495
Georg Brandl6caad7d2008-01-26 14:19:22 +00002496- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002497 added.
2498
Christian Heimesc94e2b52008-01-14 04:13:37 +00002499- sys.float_info / PyFloat_GetInfo: The floating point information
2500 object was converted from a dict to a specialized structseq object.
2501
Georg Brandl3ee81df2008-05-17 18:14:43 +00002502- Patch #1816: Added sys.flags structseq. It exposes the status of
2503 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002504
Georg Brandl3ee81df2008-05-17 18:14:43 +00002505- Objects/structseq.c: Implemented new structseq representation. The
2506 patch makes structseqs (e.g. the return value of os.stat) more
2507 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002508
Georg Brandl3ee81df2008-05-17 18:14:43 +00002509- Patch #1700288: added a type attribute cache that caches method
2510 accesses, resulting in speedups in heavily object-oriented code.

2518 envvar and sys.dont_write_bytecode attribute. All these can be set
2519 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002520
Georg Brandl3ee81df2008-05-17 18:14:43 +00002521- Improve some exception messages when Windows fails to load an
2522 extension module. Now we get for example '%1 is not a valid Win32
2523 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002524

Georg Brandl3ee81df2008-05-17 18:14:43 +00002534- Compiler now generates simpler and faster code for dictionary
2535 literals. The oparg for BUILD_MAP now indicates an estimated
2536 dictionary size. There is a new opcode, STORE_MAP, for adding
2537 entries to the dictionary.

2580
Georg Brandl3ee81df2008-05-17 18:14:43 +00002581- The enumerate() builtin function is no longer bounded to sequences
2582 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2583 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002584
Georg Brandl3ee81df2008-05-17 18:14:43 +00002585- Issue #1686386: Tuple's tp_repr did not take into account the
2586 possibility of having a self-referential tuple, which is possible
2587 from C code. Nor did object's tp_str consider that a type's tp_str
2588 could do something that could lead to an inifinite recursion.
2589 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2590 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002592- Issue #1164: It was possible to trigger deadlock when using the
2593 'print' statement to write to a file since the GIL was not released
2594 as needed. Now PyObject_Print() does the right thing along with
2595 various tp_print implementations of the built-in types and those in
2596 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00002605- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002606 PyObject_Call() never calling back out to Python code to trigger
2607 recursion depth updates/checks. Required the creation of a static
2608 RuntimeError instance in case normalizing an exception put the
2609 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00002626 __*__ attributes. (Some already existed, e.g., __doc__ and
2627 __name__.)

2634
Collin Winter62903052007-05-18 23:11:24 +00002635- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002636 "except E as target:". This is to provide forwards compatibility
2637 with Python 3.0.

2643
Vinay Sajip8549ce32007-05-06 17:53:37 +00002644- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002645 setting a plain string, ie don't expand to single letter identifiers.
2646
Raymond Hettinger13936692007-04-11 18:40:58 +00002647- Request #1191699: Slices can now be pickled.

2657
Guido van Rossum143b5642007-03-23 04:58:42 +00002658- Bug #1683368: The object.__init__() and object.__new__() methods are
2659 now stricter in rejecting excess arguments. The only time when
2660 either allows excess arguments is when it is not overridden and the
2661 other one is. For backwards compatibility, when both are
2662 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002663 warning later). Also, type.__init__() insists on the same signature
2664 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002665
Georg Brandl3ee81df2008-05-17 18:14:43 +00002666- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2667 object to complex using its __complex__() method before falling back
2668 to the __float__() method. Therefore, the functions in the cmath
2669 module now can operate on objects that define a __complex__()
2670 method.

2687
Georg Brandl7b9c5552007-03-12 14:30:05 +00002688- Bug #1678647: write a newline after printing an exception in any
2689 case, even when converting the value to a string failed.
2690
Georg Brandl871f1bc2007-03-12 13:17:36 +00002691- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002692 its argument, if it exists. If not, it will work like before. This
2693 allows customizing the output of dir() in the presence of a
2694 __getattr__().

2698
Georg Brandl3ee81df2008-05-17 18:14:43 +00002699- Patch #1675981: remove unreachable code from ``type.__new__()``

2704 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002705
Georg Brandlaa2321b2007-03-07 00:40:28 +00002706- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002707 makes the filenames the warning module prints much more sensible
2708 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002721- Patch #1674228: when assigning a slice (old-style), check for the
2722 sq_ass_slice instead of the sq_slice slot.
2723
Georg Brandl3ee81df2008-05-17 18:14:43 +00002724- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00002827 generator expressions (x for x, in ... ) works again. Fixing this
2828 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00002868- Removed uses of dict.has_key() from distutils, and uses of

Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Patch #1530482: add pydoc.render_doc() which returns the

3292
Georg Brandl92a6bae2007-03-13 17:43:32 +00003293- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003294 are set for invalid interpolation sequences that would lead to
3295 errors on reading back those values.

Collin Winter22c42ba2007-03-10 02:51:26 +00003330

3349
Georg Brandl3ee81df2008-05-17 18:14:43 +00003350- unittest now verifies more of its assumptions. In particular,
3351 TestCase and TestSuite subclasses (not instances) are no longer
3352 accepted in TestSuite.addTest(). This should cause no
3353 incompatibility since it never made sense with ordinary subclasses
3354 -- the failure just occurred later, with a more cumbersome
3355 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003642 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003743- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003744 time so that opening a database previously created with the DB_DUP
3745 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3746 opens. Specifically: dictionary assignment to a DB object will
3747 replace all values for a given key when the database allows
3748 duplicate values. DB users should use DB.put(k, v) when they want
3749 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003750

3757 dots only if they occur on a single line, as opposed to the previous
3758 behavior of quoting dots if they are the second character of any
3759 line.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004028- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004029 periodic threadstate and signal checking in tight loops. By
4030 default, this option is turned-off. It should only be enabled in
4031 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00004088
Georg Brandl3ee81df2008-05-17 18:14:43 +00004089- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4090 to ``PyTuple_SetItem``, it can be used to populate a brand new

4103
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4105 of w# format code incorrectly truncated the length to an int, even
4106 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4107 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004137- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4138 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004139

Georg Brandl3ee81df2008-05-17 18:14:43 +00004165- Removed the macfs module. It had been deprecated since Python 2.5.
4166 This lead to the deprecation of macostools.touched() as it relied
4167 solely on macfs and was a no-op under OS X.
