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.
199

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 +00001100- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

1201 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1202 for catch_warnings() also led to an improvement in the raising of a
1203 DeprecationWarning related to warnings.warn_explicit().
1204

1227
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001228- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001269What's New in Python 2.6 beta 3?
1270================================
1271
Barry Warsaw07a4a382008-08-21 01:15:08 +00001272*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001273
1274Core and Builtins
1275-----------------
1276
Guido van Rossumf8402962008-08-20 15:01:50 +00001277- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1278 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1279 extensions do not automatically benefit from the class attribute
1280 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1281 to their tp_flags field if they care. This is a backwards
1282 compatibility feature; in 3.0, all types will use the cache by
1283 default.
1284
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001285- Keyword arguments can now follow starred arguments. (``f(a, *args,
1286 keyword=23)`` is now valid syntax.)
1287
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001288- ctypes function pointers that are COM methods have a boolean True
1289 value again.
1290
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001291- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1292 by denying s# to parse objects that have a releasebuffer procedure,
1293 and introducing s*.
1294
Georg Brandl1e13ea92008-08-11 09:07:59 +00001295- Issue #3537: Fix an assertion failure when an empty but presized dict
1296 object was stored in the freelist.
1297
Mark Dickinsonb6467572008-08-04 21:30:09 +00001298- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1299 ValueError consistently across platforms.
1300
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001301- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1302 (64bit Unix, for example), unichr() would truncate its argument and return
1303 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1304
Neal Norwitze7d8be82008-07-31 17:17:14 +00001305- Apply security patches from Apple.
1306
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001307- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1308 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1309
Antoine Pitrou92f82162008-07-25 22:22:08 +00001310- Issue #1819: function calls with several named parameters are now on
1311 average 35% faster (as measured by pybench).
1312
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001313- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1314 the python debugger steps into a class statement: the free variables (local
1315 variables defined in an outer scope) would be deleted from the outer scope.
1316
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001317- Issue #2620: Overflow checking when allocating or reallocating memory
1318 was not always being done properly in some python types and extension
1319 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1320 all been updated to perform better checks and places in the code that
1321 would previously leak memory on the error path when such an allocation
1322 failed have been fixed.
1323

1325-------
1326

1330 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1331
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001332- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1333 version reported by these tools does not necessarily follow the python
1334 version numbering scheme, so the module is less strict when parsing it.
1335
Nick Coghlanf70385a2008-08-18 12:42:46 +00001336- Issue #2235: Added Py3k warnings for types which will become unhashable
1337 under the stricter __hash__ inheritance rules in 3.0. Several types
1338 which did not meet the rules for hash invariants and were already
1339 unhashable in 3.0 have now been explicitly flagged as unhashable in
1340 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1341 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1342
Brett Cannon88f801d2008-08-18 00:46:22 +00001343- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1351
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001352- Issue #3575: Incremental decoder's decode function now takes bytearray
1353 by using 's*' instead of 't#'.
1354
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001355- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001356 fails unicode conversion on 2nd parameter. (windows only)
1357
Facundo Batista94f243a2008-08-17 03:38:39 +00001358- Issue 2464. urllib2 now supports a malformation in the URL received
1359 in a redirect.
1360
Brett Cannonabe423e2008-08-16 21:47:07 +00001361- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001362 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001363
Facundo Batistaeb90b782008-08-16 14:44:07 +00001364- Issue #2776: fixed small issue when handling an URL with double slash
1365 after a 302 response in the case of not going through a proxy.
1366
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001367- Issue #2676: in the email package, content-type parsing was hanging on
1368 pathological input because of quadratic or exponential behaviour of a
1369 regular expression.
1370
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001371- Issue #3476: binary buffered reading through the new "io" library is now
1372 thread-safe.
1373
Brett Cannonbf3157b2008-08-14 05:00:03 +00001374- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1375 since mimetools itself is deprecated. Because modules are cached, all
1376 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1377
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001378- Issue #3134: shutil referenced undefined WindowsError symbol.
1379
Robert Schuppenies14646332008-08-10 11:01:53 +00001380- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1381 menu entries were not deleted.
1382
Brett Cannon83e81842008-08-09 23:30:55 +00001383- Copied the implementation of reduce() to _functools.reduce() to have a
1384 version that did not raise a DeprecationWarning under -3.
1385
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001386- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1387 a MemoryError rather than silently stop the iteration.
1388
Guido van Rossum59ce9012008-08-09 14:55:34 +00001389- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1390 to _sre.compile() will now be rejected. This should not affect anybody
1391 since the re.compile() function never generates invalid re-bytecode.
1392
Skip Montanaroa032bf42008-08-08 22:52:51 +00001393- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

Antoine Pitroude781a42008-08-09 12:43:23 +00001412 asking for a specific length. This problem only affected files opened
1413 using the new "io" module, not the built-in open() function.

1439 file name rather than a ZipInfo instance, so files are extracted with
1440 mode 0600 rather than 000 under Unix.
1441
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001442- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001457- Issue #643841: The language reference now provides more detailed
1458 coverage of the lookup process for special methods. The disclaimers
1459 regarding lack of coverage of new-style classes have also been
1460 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001463What's New in Python 2.6 beta 2?
1464================================
1465
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001466*Release date: 17-Jul-2008*
1467
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001468Core and Builtins
1469-----------------
1470
Georg Brandl3e483f62008-07-16 22:57:41 +00001471- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1472 its methods now allow for items objects that can be converted to
1473 an integer using operator.index().
1474
Mark Dickinson64b7e502008-07-16 09:40:03 +00001475- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1476 produced a ValueError instead of giving the correct float.
1477
Eric Smitha5fa5a22008-07-16 00:11:49 +00001478- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1479 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1480
Mark Dickinson7103aa42008-07-15 19:08:33 +00001481- Issue #3008: the float type has a new instance method 'float.hex'
1482 and a new class method 'float.fromhex' to convert floating-point
1483 numbers to and from hexadecimal strings, respectively.
1484
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001485- Issue #2235: __hash__ is once again inherited by default. To allow
1486 collections.Hashable to remain meaningful in the presence of the
1487 default hash implementation (object.__hash__), it is now possible
1488 to explicit block inheritance of hash by setting __hash__=None at
1489 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1490 level.
1491
Nick Coghlanb028f502008-07-13 14:52:36 +00001492- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1493 the parent module cannot be found while performing an absolute import.
1494 This means that an incorrectly defined __package__ attribute will
1495 now only prevent relative imports in that module rather than causing
1496 all imports from that module to fail.
1497
Nick Coghlan14ff9942008-07-08 14:21:42 +00001498- Issue #2517: Allow unicode messages in Exceptions again by correctly
1499 bypassing the instance dictionary when looking up __unicode__ on
1500 new-style classes.
1501
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001502- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1503 set to a custom object whose write() method happens to install
1504 another file in sys.stdout.
1505
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001506- Issue #3088: Corrected a race condition in classes derived from
1507 threading.local: the first member set by a thread could be saved in
1508 another thread's dictionary.
1509
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001510- Issue #3004: Minor change to slice.indices(): the start and stop
1511 arguments are now treated identically, making the behaviour easier
1512 to describe and understand. For example, slice(None, -10,
1513 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1514 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1515 10, -1).
1516
Georg Brandl278fc502008-07-19 12:46:12 +00001517- Issue #3219: Calling a function with repeated keyword arguments,
1518 f(a=2, a=23), would not cause a syntax error. This was a regression
1519 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001520
Georg Brandl278fc502008-07-19 12:46:12 +00001521- Issue #2862: Make int and float freelist management consistent with
1522 other freelists. Changes their CompactFreeList apis into
1523 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001524

1526-------
1527
Thomas Heller57adf222008-08-14 19:10:48 +00001528- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1529 api functions without holding the GIL, which could lead to a fatal
1530 error when they failed.
1531
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001532- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00001540- Issue #3125: Remove copy_reg in multiprocessing and replace it with
1541 ForkingPickler.register() to resolve conflict with ctypes.
1542
Vinay Sajip51e65192008-07-18 09:01:10 +00001543- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00001544
Thomas Heller880f5292008-07-15 19:39:38 +00001545- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1546 a valid dlerror() message.
1547
Thomas Heller2bad6572008-07-15 17:19:50 +00001548- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1549 incomplete structure was created.
1550

1554
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001555- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001556
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001557- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1558 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001559 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001560 content-length. The problem had been corrected in the 2.4 branch, but never
1561 merged into trunk.
1562
Georg Brandle78fbcc2008-07-05 10:13:36 +00001563- Issue #2663: add filtering capability to shutil.copytree().

1568
1569- Issue #1746: Correct handling of zipfile archive comments (previously
1570 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001571 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001572
Vinay Sajip51e65192008-07-18 09:01:10 +00001573- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001574 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00001575
Nick Coghlanc060b0e2008-07-02 13:09:19 +00001576- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1577 handling is now the same as that of other special attributes like __name__).
1578
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001579- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
1580 removal in Python 3.0 in favor of urllib2.urlopen().

2032 original Python code has been kept as backup). This will allow for
2033 using the 'warning's machinery in such places as the parser where
2034 use of pure Python code is not possible. Both the ``showarning()``
2035 and ``formatwarning()`` gain an optional 'line' argument which is
2036 not called by default for backwards-compatibility reasons. Setting
2037 ``warnings.showwarning()`` to an implementation that lacks support
2038 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002101- Issue #2550: The approach used by client/server code for obtaining
2102 ports to listen on in network-oriented tests has been refined in an
2103 effort to facilitate running multiple instances of the entire
2104 regression test suite in parallel without issue.
2105 test_support.bind_port() has been fixed such that it will always
2106 return a unique port -- which wasn't always the case with the
2107 previous implementation, especially if socket options had been set
2108 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2109 new implementation of bind_port() will actually raise an exception
2110 if it is passed an AF_INET/SOCK_STREAM socket with either the
2111 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2112 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2113 the socket it's been passed. This currently only applies to
2114 Windows. This option prevents any other sockets from binding to the
2115 host/port we've bound to, thus removing the possibility of the
2116 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2117 when a second SOCK_STREAM socket binds and accepts to a host/port
2118 that's already been bound by another socket. The optional preferred
2119 port parameter to bind_port() has been removed. Under no
2120 circumstances should tests be hard coding ports!
2121
2122 test_support.find_unused_port() has also been introduced, which will
2123 pass a temporary socket object to bind_port() in order to obtain an
2124 unused port. The temporary socket object is then closed and
2125 deleted, and the port is returned. This method should only be used
2126 for obtaining an unused port in order to pass to an external program
2127 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2128 a parameter to a server-oriented class that doesn't give you direct
2129 access to the underlying socket used.
2130
2131 Finally, test_support.HOST has been introduced, which should be used
2132 for the host argument of any relevant socket calls (i.e. bind and
2133 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002134
2135 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002136 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002137 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2138 test_asynchat and test_socket_ssl.
2139
Georg Brandl3ee81df2008-05-17 18:14:43 +00002140 It is now possible for multiple instances of the regression test
2141 suite to run in parallel without issue.

2408-----------------
2409
Fred Drakea8ee94b2008-03-01 02:45:07 +00002410- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002411 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002412
Georg Brandlad61bc82008-02-23 15:11:18 +00002413- Issue #2067: file.__exit__() now calls subclasses' close() method.
2414
2415- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002416
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002417- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002418 issue 215555 for a discussion.
2419
Eric Smitha73fbe72008-02-23 03:09:44 +00002420- Added the future_builtins module, which contains hex() and oct().
2421 These are the PEP 3127 version of these functions, designed to be
2422 compatible with the hex() and oct() builtins from Python 3.0. They
2423 differ slightly in their output formats from the existing, unchanged
2424 Python 2.6 builtins. The expected usage of the future_builtins
2425 module is:
2426 from future_builtins import hex, oct
2427
Eric Smith7ef40bf2008-02-20 23:34:22 +00002428- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2429 exponents for exponents with absolute value < 100. Follows C99
2430 standard. This is a change on Windows, which would use 3 digits.
2431 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2432 so that any alterations it does to the resulting string will be
2433 available in stringlib/formatter.h (for float.__format__).
2434
Eric Smith5a3c1352008-02-19 13:21:56 +00002435- Implemented PEP 3101, Advanced String Formatting. This adds a new
2436 builtin format(); a format() method for str and unicode; a
2437 __format__() method to object, str, unicode, int, long, float, and
2438 datetime; the class string.Formatter; and the C API
2439 PyObject_Format().
2440
Georg Brandl3ee81df2008-05-17 18:14:43 +00002441- Fixed several potential crashes, all caused by specially crafted
2442 __del__ methods exploiting objects in temporarily inconsistent
2443 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002444
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002445- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002446 prevent a possible crash: an Abstract Base Class would try to access
2447 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002448
Georg Brandl3ee81df2008-05-17 18:14:43 +00002449- Fixed repr() and str() of complex numbers with infinity or nan as
2450 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002452- Clear all free lists during a gc.collect() of the highest generation
2453 in order to allow pymalloc to free more arenas. Python may give back
2454 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002455
Georg Brandl3ee81df2008-05-17 18:14:43 +00002456- Issue #2045: Fix an infinite recursion triggered when printing a
2457 subclass of collections.defaultdict, if its default_factory is set
2458 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002459
Christian Heimesf75dbef2008-02-08 00:11:31 +00002460- Fixed a minor memory leak in dictobject.c. The content of the free
2461 list was not freed on interpreter shutdown.
2462
Georg Brandl3ee81df2008-05-17 18:14:43 +00002463- Limit free list of method and builtin function objects to 256
2464 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002465
Georg Brandl3ee81df2008-05-17 18:14:43 +00002466- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2467 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002468 to compact the internal free lists of pre-allocted ints and floats.
2469
Georg Brandl3ee81df2008-05-17 18:14:43 +00002470- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2471 calls. Python expected the return type int but the fork familie
2472 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002473
Georg Brandl3ee81df2008-05-17 18:14:43 +00002474- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2484 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002485
Georg Brandl3ee81df2008-05-17 18:14:43 +00002486- Patch #1473257: generator objects gain a gi_code attribute. This is
2487 the same object as the func_code attribute of the function that
2488 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002489
Georg Brandl3ee81df2008-05-17 18:14:43 +00002490- Issue #1920: "while 0" statements were completely removed by the
2491 compiler, even in the presence of an "else" clause, which is
2492 supposed to be run when the condition is false. Now the compiler
2493 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002494
Guido van Rossumeead05f2008-01-24 18:21:02 +00002495- A few crashers fixed: weakref_in_del.py (issue #1377858);
2496 loosing_dict_ref.py (issue #1303614, test67.py);
2497 borrowed_ref_[34].py (not in tracker).
2498
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002499- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002500 suppressed while an extension is loaded by calling SetErrorMode in

2502
Georg Brandl3ee81df2008-05-17 18:14:43 +00002503- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002504 several extension methods and modules do not work without unicode
2505 support.
2506
Georg Brandl26543b12008-01-21 18:36:51 +00002507- Issue #1882: when compiling code from a string, encoding cookies in the
2508 second line of code were not always recognized correctly.
2509
Georg Brandl14404b62008-01-19 19:27:05 +00002510- Issue #1679: "0x" was taken as a valid integer literal.
2511
Georg Brandl6caad7d2008-01-26 14:19:22 +00002512- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002513 added.
2514
Christian Heimesc94e2b52008-01-14 04:13:37 +00002515- sys.float_info / PyFloat_GetInfo: The floating point information
2516 object was converted from a dict to a specialized structseq object.
2517
Georg Brandl3ee81df2008-05-17 18:14:43 +00002518- Patch #1816: Added sys.flags structseq. It exposes the status of
2519 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002520
Georg Brandl3ee81df2008-05-17 18:14:43 +00002521- Objects/structseq.c: Implemented new structseq representation. The
2522 patch makes structseqs (e.g. the return value of os.stat) more
2523 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002524
Georg Brandl3ee81df2008-05-17 18:14:43 +00002525- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002533- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2534 envvar and sys.dont_write_bytecode attribute. All these can be set
2535 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002537- Improve some exception messages when Windows fails to load an
2538 extension module. Now we get for example '%1 is not a valid Win32
2539 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002540

Christian Heimes0a8143f2007-12-18 23:22:54 +00002546- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002547 and INF. float("nan"), float("inf") and float("-inf") now work on
2548 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Compiler now generates simpler and faster code for dictionary
2551 literals. The oparg for BUILD_MAP now indicates an estimated
2552 dictionary size. There is a new opcode, STORE_MAP, for adding
2553 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002582- Patch #1739468: Directories and zipfiles containing a __main__.py
2583 file can now be directly executed by passing their name to the
2584 interpreter. The directory/zipfile is automatically inserted as the
2585 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002586
Georg Brandl3ee81df2008-05-17 18:14:43 +00002587- Issue #1265: Fix a problem with sys.settrace, if the tracing
2588 function uses a generator expression when at the same time the
2589 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002590
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002591- sets and frozensets now have an isdisjoint() method.

2596
Georg Brandl3ee81df2008-05-17 18:14:43 +00002597- The enumerate() builtin function is no longer bounded to sequences
2598 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2599 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002600
Georg Brandl3ee81df2008-05-17 18:14:43 +00002601- Issue #1686386: Tuple's tp_repr did not take into account the
2602 possibility of having a self-referential tuple, which is possible
2603 from C code. Nor did object's tp_str consider that a type's tp_str
2604 could do something that could lead to an inifinite recursion.
2605 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2606 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002607
Georg Brandl3ee81df2008-05-17 18:14:43 +00002608- Issue #1164: It was possible to trigger deadlock when using the
2609 'print' statement to write to a file since the GIL was not released
2610 as needed. Now PyObject_Print() does the right thing along with
2611 various tp_print implementations of the built-in types and those in
2612 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002613
Georg Brandl3ee81df2008-05-17 18:14:43 +00002614- Issue #1147: Exceptions were directly allowing string exceptions in
2615 their throw() method even though string exceptions no longer
2616 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002617
Georg Brandl3ee81df2008-05-17 18:14:43 +00002618- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002620
Brett Cannon1e534b52007-09-07 04:18:30 +00002621- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002622 PyObject_Call() never calling back out to Python code to trigger
2623 recursion depth updates/checks. Required the creation of a static
2624 RuntimeError instance in case normalizing an exception put the
2625 recursion check value past its limit. Fixes crashers
2626 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002627

Neal Norwitz0ac60192007-05-27 04:08:54 +00002641- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002642 __*__ attributes. (Some already existed, e.g., __doc__ and
2643 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002644
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002645- Add -3 option to the interpreter to warn about features that are
2646 deprecated and will be changed/removed in Python 3.0.
2647
Georg Brandl2134e752007-05-21 20:34:16 +00002648- Patch #1686487: you can now pass any mapping after '**' in function
2649 calls.
2650
Collin Winter62903052007-05-18 23:11:24 +00002651- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002652 "except E as target:". This is to provide forwards compatibility
2653 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002654
Brett Cannon229cee22007-05-05 01:34:02 +00002655- Deprecate BaseException.message as per PEP 352.
2656
Georg Brandl3ee81df2008-05-17 18:14:43 +00002657- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002658 inherited from a builtin base.
2659
Vinay Sajip8549ce32007-05-06 17:53:37 +00002660- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002661 setting a plain string, ie don't expand to single letter identifiers.
2662
Raymond Hettinger13936692007-04-11 18:40:58 +00002663- Request #1191699: Slices can now be pickled.
2664
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002665- Request #1193128: str.translate() now allows a None argument for
2666 translations that only remove characters without re-mapping the
2667 remaining characters.
2668
Georg Brandl5cb76c12007-03-21 09:00:39 +00002669- Patch #1682205: a TypeError while unpacking an iterable is no longer
2670 masked by a generic one with the message "unpack non-sequence".
2671
Neal Norwitzaa754b72007-03-21 06:39:48 +00002672- Remove unused file Python/fmod.c.
2673
Guido van Rossum143b5642007-03-23 04:58:42 +00002674- Bug #1683368: The object.__init__() and object.__new__() methods are
2675 now stricter in rejecting excess arguments. The only time when
2676 either allows excess arguments is when it is not overridden and the
2677 other one is. For backwards compatibility, when both are
2678 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002679 warning later). Also, type.__init__() insists on the same signature
2680 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002681
Georg Brandl3ee81df2008-05-17 18:14:43 +00002682- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2683 object to complex using its __complex__() method before falling back
2684 to the __float__() method. Therefore, the functions in the cmath
2685 module now can operate on objects that define a __complex__()
2686 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002687
Georg Brandl3ee81df2008-05-17 18:14:43 +00002688- Patch #1623563: allow __class__ assignment for classes with
2689 __slots__. The old and the new class are still required to have the
2690 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002691

2696 ``object.__reduce_ex__()`` is called with an object that is faking
2697 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002698
Georg Brandl3ee81df2008-05-17 18:14:43 +00002699- Patch #1680015: Don't modify __slots__ tuple if it contains an

2703
Georg Brandl7b9c5552007-03-12 14:30:05 +00002704- Bug #1678647: write a newline after printing an exception in any
2705 case, even when converting the value to a string failed.
2706
Georg Brandl871f1bc2007-03-12 13:17:36 +00002707- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002708 its argument, if it exists. If not, it will work like before. This
2709 allows customizing the output of dir() in the presence of a
2710 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002711
Collin Winter276887b2007-03-12 16:11:39 +00002712- Patch #922167: Python no longer segfaults when faced with infinitely
2713 self-recursive reload() calls (as reported by bug #742342).
2714
Georg Brandl3ee81df2008-05-17 18:14:43 +00002715- Patch #1675981: remove unreachable code from ``type.__new__()``

2719 parthensized forms. This means complex(repr(x)) now works instead of
2720 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002721
Georg Brandlaa2321b2007-03-07 00:40:28 +00002722- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002723 makes the filenames the warning module prints much more sensible
2724 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002725
Georg Brandl49aafc92007-03-07 00:34:46 +00002726- Variant of patch #697613: don't exit the interpreter on a SystemExit
2727 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002728 variable is given, but break into the interactive interpreter just
2729 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002737- Patch #1674228: when assigning a slice (old-style), check for the
2738 sq_ass_slice instead of the sq_slice slot.
2739
Georg Brandl3ee81df2008-05-17 18:14:43 +00002740- When printing an unraisable error, don't print exceptions. before
2741 the name. This duplicates the behavior whening normally printing
2742 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003275 AttributeError instead of an IOError when the server's response
3276 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003277

3292
Georg Brandl3ee81df2008-05-17 18:14:43 +00003293- Patch #1530482: add pydoc.render_doc() which returns the

3308
Georg Brandl92a6bae2007-03-13 17:43:32 +00003309- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003310 are set for invalid interpolation sequences that would lead to
3311 errors on reading back those values.

3354 returned string up to the first NUL character.

3365
Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- unittest now verifies more of its assumptions. In particular,
3367 TestCase and TestSuite subclasses (not instances) are no longer
3368 accepted in TestSuite.addTest(). This should cause no
3369 incompatibility since it never made sense with ordinary subclasses
3370 -- the failure just occurred later, with a more cumbersome
3371 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003658 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00003760 time so that opening a database previously created with the DB_DUP
3761 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3762 opens. Specifically: dictionary assignment to a DB object will
3763 replace all values for a given key when the database allows
3764 duplicate values. DB users should use DB.put(k, v) when they want
3765 to store duplicates; not DB[k] = v.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004044- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004045 periodic threadstate and signal checking in tight loops. By
4046 default, this option is turned-off. It should only be enabled in

Christian Heimes5b970ad2008-02-06 13:33:44 +00004104
Georg Brandl3ee81df2008-05-17 18:14:43 +00004105- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4106 to ``PyTuple_SetItem``, it can be used to populate a brand new

4119
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4121 of w# format code incorrectly truncated the length to an int, even
4122 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4123 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004124
Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4147 outside of pystate.c and should not be necessary.
4148
Georg Brandl3ee81df2008-05-17 18:14:43 +00004149- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4150 absolute imports. In earlier versions they might have used relative
4151 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004152
Georg Brandl3ee81df2008-05-17 18:14:43 +00004153- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4154 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004155
Georg Brandl3ee81df2008-05-17 18:14:43 +00004156- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004181- Removed the macfs module. It had been deprecated since Python 2.5.
4182 This lead to the deprecation of macostools.touched() as it relied
4183 solely on macfs and was a no-op under OS X.
