11
12Core and Builtins
13-----------------
14
Eric Smithc4ab8332009-11-29 17:40:57 +000015- Issue #3382: 'F' formatting for float and complex now convert the
16 result to upper case. This only affects 'inf' and 'nan', since 'f'
17 no longer converts to 'g' for large values.
18
Mark Dickinson9dd5e162009-11-23 20:54:09 +000019- Remove switch from "%f" formatting to "%g" formatting for floats
20 larger than 1e50 in absolute value.
21
Mark Dickinson18cfada2009-11-23 18:46:41 +000022- Remove restrictions on precision when formatting floats. E.g.,
23 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
24 requested 120 significant digits instead.
25
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000026- Add Py3k warnings for parameter names in parenthesis.
27
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +000028- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +000029
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000030- Issue #7085: Fix crash when importing some extensions in a thread
31 on MacOSX 10.6.
32
Mark Dickinsonb678de82009-11-19 18:41:49 +000033- Issue #7117: repr(x) for a float x returns a result based on the
34 shortest decimal string that's guaranteed to round back to x under
35 correct rounding (with round-half-to-even rounding mode).
36 Previously it gave a string based on rounding x to 17 decimal digits.
37 repr(x) for a complex number behaves similarly. On platforms where
38 the correctly-rounded strtod and dtoa code is not supported (see below),
39 repr is unchanged.
40
41- Issue #7117: On almost all platforms: float-to-string and
42 string-to-float conversions within Python are now correctly rounded.
43 Places these conversions occur include: str for floats and complex
44 numbers; the float and complex constructors; old-style and new-style
45 numeric formatting; serialization and deserialization of floats and
46 complex numbers using marshal, pickle and json; parsing of float and
47 imaginary literals in Python code; Decimal-to-float conversion.
48
49 The conversions use a Python-adapted version of David Gay's
50 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
51 functions. This code is supported on Windows, and on Unix-like
52 platforms using gcc, icc or suncc as the C compiler. There may be a
53 small number of platforms on which correct operation of this code
54 cannot be guaranteed, so the code is not used: notably, this applies
55 to platforms where the C double format is not IEEE 754 binary64, and
56 to platforms on x86 hardware where the x87 FPU is set to 64-bit
57 precision and Python's configure script is unable to determine how
58 to change the FPU precision. On these platforms conversions use the
59 platform strtod and dtoa, as before.
60
Mark Dickinsonbd15a062009-11-18 19:33:35 +000061- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000062 now uses the correctly-rounded string <-> float conversions
63 described above (when available), and so produces correctly rounded
64 results that will display nicely under the float repr. There are
65 two related small changes: (1) round now accepts any class with an
66 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000067 floats for the second argument), and (2) an excessively large second
68 integer argument (e.g., round(1.234, 10**100)) no longer raises an
69 exception.
70
Philip Jenveyfab8be22009-11-17 02:42:26 +000071- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
72
Benjamin Petersone36199b2009-11-12 23:39:44 +000073- Fix several issues with compile(). The input can now contain Windows and Mac
74 newlines and is no longer required to end in a newline.
75
Mark Dickinsonc04c7c52009-10-26 22:28:14 +000076- Remove length limitation when constructing a complex number from a
77 unicode string.
78
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +000079- Issue #7244: itertools.izip_longest() no longer ignores exceptions
80 raised during the formation of an output tuple.
81
Mark Dickinson8d87dc02009-10-25 20:39:06 +000082- Issue #1087418: Boost performance of bitwise operations for longs.
83
Antoine Pitrouefb60c02009-10-20 21:29:37 +000084- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
85 fixes the problem of some exceptions being thrown at shutdown when the
86 interpreter is killed. Patch by Adam Olsen.
87
Eric Smithc12781a2009-10-19 14:38:14 +000088- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and
89 note that they are unsafe and deprecated.
90
Vinay Sajip03d5c342009-10-16 14:06:44 +000091- Issue #7120: logging: Removed import of multiprocessing which is causing
92 crash in GAE.
93
Benjamin Peterson196b0922009-10-15 15:44:46 +000094- Issue #7140: The __dict__ of a module should not be cleared unless the module
95 is the only object holding a reference to it.
96
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +000097- Issue #1754094: Improve the stack depth calculation in the compiler.
98 There should be no other effect than a small decrease in memory use.
99 Patch by Christopher Tur Lesniewski-Laas.
100
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000101- Issue #7084: Fix a (very unlikely) crash when printing a list from one

105 The tables for code points representing numeric values, white spaces or line
106 breaks are now generated from the official Unicode Character Database files,
107 and include information from the Unihan.txt file.

114 and Jani Hakala.
115
Mark Dickinson7e7a3ec2009-09-29 19:01:06 +0000116- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
117 of producing internally inconsistent Python longs.
118
Philip Jenveydbf3b252009-09-29 04:32:44 +0000119- Issue #6990: Fix threading.local subclasses leaving old state around

132
Georg Brandl0674d3f2009-09-16 20:30:09 +0000133- Issue #6844: Do not emit DeprecationWarnings when accessing a "message"
134 attribute on exceptions that was set explicitly.
135

179
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000180- When no module is given in a relative import, the module field of the
181 ImportFrom AST node is now None instead of an empty string.
182
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000183- Assignment to None using import statements now raises a SyntaxError.
184

Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000189 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000190
Raymond Hettinger578a2282009-05-29 04:58:52 +0000191- Issue #5982: staticmethod and classmethod now expose the wrapped
192 function with __func__.
193
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000194- Added support for multiple context managers in the same with-statement.
195 Deprecated contextlib.nested() which is no longer needed.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000197- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
198 statement and correctly lookup the __enter__ and __exit__ special methods.
199
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000200- Issue #5829: complex("1e500") no longer raises OverflowError. This
201 makes it consistent with float("1e500") and interpretation of real
202 and imaginary literals.
203
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000204- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
205
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000206- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
207 classes and instances.

R. David Murray525cffc2009-05-13 13:07:14 +0000209- Issue #5994: the marshal module now has docstrings.
210
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000211- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
212 (1) inf and nan strings with trailing whitespace were incorrectly
213 rejected; (2) parsing of strings representing infinities and nans
214 was locale aware; and (3) the interpretation of fromhex('-nan')
215 didn't match that of float('-nan').
216
Eric Smitha985a3a2009-05-05 18:26:08 +0000217- Issue #5920: For float.__format__, change the behavior with the
218 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
219 to be like 'g' but with at least one decimal point and with a
220 default precision of 12. Previously, the behavior the same but with
221 a default precision of 6. This more closely matches str(), and
222 reduces surprises when adding alignment flags to the empty
223 presentation type. This also affects the new complex.__format__ in
224 the same way.
225
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000226- Issue #5890: in subclasses of 'property' the __doc__ attribute was
227 shadowed by classtype's, even if it was None. property now
228 inserts the __doc__ into the subclass instance __dict__.
229
Antoine Pitrou653dece2009-05-04 18:32:32 +0000230- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

232
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000233- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000234 format(complex(1, 2./3), '.5') now produces a sensible result.
235
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000236- Issue #5864: Fix empty format code formatting for floats so that it
237 never gives more than the requested number of significant digits.
238
Eric Smithcac7af62009-04-27 19:04:37 +0000239- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
240 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
241
Martin v. Löwis99f27792009-04-26 00:53:18 +0000242- Issue #4971: Fix titlecase for characters that are their own
243 titlecase, but not their own uppercase.
244
Eric Smith068f0652009-04-25 21:40:15 +0000245- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
246 _PyOS_double_to_string or PyOS_double_to_string.
247
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000248- Issue #5283: Setting __class__ in __del__ caused a segfault.
249
Mark Dickinson95bc9802009-04-24 12:46:53 +0000250- Issue #5816: complex(repr(z)) now recovers z exactly, even when
251 z involves nans, infs or negative zeros.
252
Eric Smithaca19e62009-04-22 13:29:05 +0000253- Implement PEP 378, Format Specifier for Thousands Separator, for
254 floats, ints, and longs.
255
256- Issue #5515: 'n' formatting for ints, longs, and floats handles
257 leading zero formatting poorly.
258
259- Issue #5772: For float.__format__, don't add a trailing ".0" if
260 we're using no type code and we have an exponent.
261
Mark Dickinson6736cf82009-04-20 21:13:33 +0000262- Issue #3166: Make long -> float (and int -> float) conversions
263 correctly rounded.
264
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000265- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
266 some builtin types.
267
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000268- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000269 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000270
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000271- Issue #5759: float() didn't call __float__ on str subclasses.
272
Georg Brandl3c4a5462009-04-12 12:08:12 +0000273- Issue #5704: the "-3" command-line option now implies "-t".
274
R. David Murray0374a822009-04-09 21:54:50 +0000275- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
276 its clarity and its speed.
277
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000278- Issue #2396: the memoryview object was backported from Python 3.1.

282
Brett Cannon15ba4da2009-04-01 18:03:59 +0000283- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
284
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000285- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
286 the end sys.path, for compatibility with the system install of Python.
287
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000288- Issue #4688: Add a heuristic so that tuples and dicts containing only
289 untrackable objects are not tracked by the garbage collector. This can
290 reduce the size of collections and therefore the garbage collection overhead
291 on long-running programs, depending on their particular use of datatypes.
292
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000293- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
294 improve its performance. Long divisions and remainder operations
295 are now between 50% and 150% faster.
296
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000297- Issue #4258: Make it possible to use base 2**30 instead of base
298 2**15 for the internal representation of integers, for performance
299 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
300 --enable-big-digits option to configure, which overrides the
301 default. Add sys.long_info structseq to provide information about
302 the internal format.
303
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000304- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
305 result traceback.__members__ no longer exists.)

Brett Cannon6c4cff02009-03-11 04:51:06 +0000314- Issue #3652: Make the 'line' argument for warnings.showwarning() a
315 requirement. Means the DeprecationWarning from Python 2.6 can go away.
316
Eric Smithe9fb6862009-02-20 14:02:36 +0000317- Issue #5247: Improve error message when unknown format codes are
318 used when using str.format() with str, unicode, long, int, and
319 float arguments.
320
Raymond Hettinger08259e82009-02-18 23:10:19 +0000321- Running Python with the -3 option now also warns about classic division
322 for ints and longs.
323
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000324- Issue #5260: Long integers now consume less memory: average
325 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
326 on a 64-bit system.
327
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000328- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

333
Benjamin Petersone18ef192009-01-20 14:21:16 +0000334- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
335
Georg Brandl29c6a282009-04-05 20:23:13 +0000336- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000337 were suppressing all exceptions. These include list(), filter(), map(),
338 zip(), and bytearray().
339
Benjamin Peterson596d3062009-01-19 15:42:23 +0000340- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
341 functions.
342
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000343- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

347
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000348- Issue #4935: The overflow checking code in the expandtabs() method common
349 to str, bytes and bytearray could be optimized away by the compiler, letting
350 the interpreter segfault instead of raising an error.
351
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000352- Issue #3720: Fix a crash when an iterator modifies its class and removes its

358
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000359- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
360 collecting the oldest generation) so that allocating lots of objects without
361 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000362 Martin von Löwis at

366
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000367- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
368 an existing .py counterpart, override the co_filename attributes of all
369 code objects if the original filename is obsolete (which can happen if the
370 file has been renamed, moved, or if it is accessed through different paths).
371 Patch by Ziga Seilnacht and Jean-Paul Calderone.
372
Martin v. Löwis5344c992009-01-02 20:32:55 +0000373- Issue #4075: Use OutputDebugStringW in Py_FatalError.

377
Antoine Pitrouaa687902009-01-01 14:11:22 +0000378- Issue #3680: Reference cycles created through a dict, set or deque iterator
379 did not get collected.
380
Nick Coghlan180e4002008-12-30 01:18:48 +0000381- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
382 where the tp_hash and tp_dict slots are both NULL.
383
Benjamin Peterson7af65562008-12-29 17:56:58 +0000384- Issue #4764: With io.open, IOError.filename is set when trying to open a
385 directory on POSIX systems.
386
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000387- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

391 bytearray.translate(). It was always allowed for bytes.translate().
392
Skip Montanarof205c132008-12-23 03:30:15 +0000393- Added test case to ensure attempts to read from a file opened for writing
394 fail.
395
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000396- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

406 context manager returns a value that cannot be converted to a bool.
407
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000408- Issue #4597: Fixed several opcodes that weren't always propagating
409 exceptions.
410
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000411- Issue #4445: Replace "sizeof(PyStringObject)" with
412 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
413 str instances. On a typical machine this saves 3 bytes of memory
414 (on average) per string allocation.
415
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000416- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
417 interpreter to abort ("Fatal Python error: Could not reset the stack!")
418 instead of throwing a MemoryError.
419
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000420- Issue #3689: The list reversed iterator now supports __length_hint__
421 instead of __len__. Behavior now matches other reversed iterators.
422
Benjamin Petersonc078f922008-11-21 22:27:24 +0000423- Issue #4367: Python would segfault during compiling when the unicodedata
424 module couldn't be imported and \N escapes were present.
425
Vinay Sajip213faca2008-12-03 23:22:58 +0000426- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000427 method on file objects with closefd=False. The file descriptor is still
428 kept open but the file object behaves like a closed file. The ``FileIO``
429 object also got a new readonly attribute ``closefd``.
430
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000431- Issue #4348: Some bytearray methods returned that didn't cause any change to
432 the bytearray, returned the same bytearray instead of a copy.
433
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000434- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
435

Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000438- Issue #4048: The parser module now correctly validates relative imports.
439
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000440- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
441 exec statement.
442
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000443- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
444 method does not return iterators for the 4th and 5th items.
445
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000446- Issue #4209: Enabling unicode_literals and the print_function in the same
447 __future__ import didn't work.
448
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000449- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000450 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000451
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000452- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
453 returned a path longer than MAX_PATH. (But It's doubtful this code path is
454 really executed because I cannot move to such directory on win2k)
455
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000456- Issue #4069: When set.remove(element) is used with a set element, the element
457 is temporarily replaced with an equivalent frozenset. But the eventual
458 KeyError would always report the empty frozenset([]) as the missing key. Now
459 it correctly refers to the initial element.
460
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000461- Issue #4509: Various issues surrounding resize of bytearray objects to
462 which there are buffer exports.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000476- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
477 returned them on 64bit platforms.
478
Walter Dörwalded960ac2009-05-03 22:36:33 +0000479- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
480 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
481 step. This avoids problems with counting UTF-8 bytes that ignores the effect
482 of using the replace error handler in PyUnicode_DecodeUTF8().
483
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000484- Issue #3739: The unicode-internal encoder now reports the number of characters
485 consumed like any other encoder (instead of the number of bytes).

Tarek Ziadéa5076a22009-11-29 22:20:30 +0000490- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
491 ownership when the group is not forced, because the group may be different
492 from the user's group and inherit from its container when the test is run.

1705
R. David Murray14dcd432009-10-14 13:58:07 +00001706- Issue #7058: Added save/restore for things like sys.argv and cwd to

1716 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1717 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1718 skip the tests if DISPLAY is defined but can't be used.

1724 it easy to import both normal and optimised versions of modules.
1725 test_heapq and test_warnings have been adjusted to use it, tests for
1726 other modules with both C and Python implementations in the stdlib
1727 can be adjusted to use it over time.

R. David Murray41448c52009-03-31 19:57:24 +00001735- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajip22aa4bb2009-04-16 19:15:49 +00001736 that should cause a test to be skipped are now done using import_module
R. David Murray41448c52009-03-31 19:57:24 +00001737 from test support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001838- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1839
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001840- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1841 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1842 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1843 ``printf`` function, whereas PyString_FromFormat has an independent
1844 implementation and uses "%zd" on all platforms for size_t values.
1845 This makes a difference on win64, where ``printf`` needs "%Id" to display
1846 64bit values.
1847
Benjamin Peterson97179b02008-09-09 20:55:01 +00001848- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

1852 object; previously an int would be returned for small values. the __long__
1853 method is allowed to return either an int or a long, but the behaviour of

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001856- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00001862 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001863 was correctly parsed but parsing of subsequent arguments failed.
1864
Vinay Sajip35e3b032008-09-01 14:33:59 +00001865- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001866 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1867 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1868 when given a tuple of classes as second argument, were looking up
1869 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1870 type object.
1871
Neal Norwitz18aa3882008-08-24 05:04:52 +00001872- Fix crashes on memory allocation failure found with failmalloc.

1876- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002009What's New in Python 2.6 beta 3?
2010================================
2011
Barry Warsaw07a4a382008-08-21 01:15:08 +00002012*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002013
2014Core and Builtins
2015-----------------
2016
Guido van Rossumf8402962008-08-20 15:01:50 +00002017- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2018 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2019 extensions do not automatically benefit from the class attribute
2020 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2021 to their tp_flags field if they care. This is a backwards
2022 compatibility feature; in 3.0, all types will use the cache by
2023 default.
2024
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002025- Keyword arguments can now follow starred arguments. (``f(a, *args,
2026 keyword=23)`` is now valid syntax.)
2027
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002028- ctypes function pointers that are COM methods have a boolean True
2029 value again.
2030
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002031- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2032 by denying s# to parse objects that have a releasebuffer procedure,
2033 and introducing s*.
2034
Georg Brandl1e13ea92008-08-11 09:07:59 +00002035- Issue #3537: Fix an assertion failure when an empty but presized dict
2036 object was stored in the freelist.
2037
Mark Dickinsonb6467572008-08-04 21:30:09 +00002038- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2039 ValueError consistently across platforms.
2040
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002041- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2042 (64bit Unix, for example), unichr() would truncate its argument and return
2043 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2044
Neal Norwitze7d8be82008-07-31 17:17:14 +00002045- Apply security patches from Apple.
2046
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002047- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2048 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2049
Antoine Pitrou92f82162008-07-25 22:22:08 +00002050- Issue #1819: function calls with several named parameters are now on
2051 average 35% faster (as measured by pybench).
2052
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002053- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2054 the python debugger steps into a class statement: the free variables (local
2055 variables defined in an outer scope) would be deleted from the outer scope.
2056
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002057- Issue #2620: Overflow checking when allocating or reallocating memory
2058 was not always being done properly in some python types and extension
2059 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2060 all been updated to perform better checks and places in the code that
2061 would previously leak memory on the error path when such an allocation
2062 failed have been fixed.
2063
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002064Library
2065-------
2066
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002067- Issue #3612: Added some missing basic types in ctypes.wintypes.
2068
Benjamin Petersone977ad42008-08-20 01:42:01 +00002069- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2070 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2071
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002072- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2073 version reported by these tools does not necessarily follow the python
2074 version numbering scheme, so the module is less strict when parsing it.
2075
Nick Coghlanf70385a2008-08-18 12:42:46 +00002076- Issue #2235: Added Py3k warnings for types which will become unhashable
2077 under the stricter __hash__ inheritance rules in 3.0. Several types
2078 which did not meet the rules for hash invariants and were already
2079 unhashable in 3.0 have now been explicitly flagged as unhashable in
2080 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2081 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2082
Brett Cannon88f801d2008-08-18 00:46:22 +00002083- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2084 imported into the module but exposed as part of the module's API.
2085
Brett Cannon7b96f072008-08-18 00:41:11 +00002086- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2087
Brett Cannon46225e72008-08-18 00:36:52 +00002088- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2089
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002090- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2091
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002092- Issue #3575: Incremental decoder's decode function now takes bytearray
2093 by using 's*' instead of 't#'.
2094
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002095- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002096 fails unicode conversion on 2nd parameter. (windows only)
2097
Facundo Batista94f243a2008-08-17 03:38:39 +00002098- Issue 2464. urllib2 now supports a malformation in the URL received
2099 in a redirect.
2100
Brett Cannonabe423e2008-08-16 21:47:07 +00002101- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002102 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002103
Facundo Batistaeb90b782008-08-16 14:44:07 +00002104- Issue #2776: fixed small issue when handling an URL with double slash
2105 after a 302 response in the case of not going through a proxy.
2106
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002107- Issue #2676: in the email package, content-type parsing was hanging on
2108 pathological input because of quadratic or exponential behaviour of a
2109 regular expression.
2110
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002111- Issue #3476: binary buffered reading through the new "io" library is now
2112 thread-safe.
2113
Brett Cannonbf3157b2008-08-14 05:00:03 +00002114- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2115 since mimetools itself is deprecated. Because modules are cached, all
2116 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2117
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002118- Issue #3134: shutil referenced undefined WindowsError symbol.
2119
Robert Schuppenies14646332008-08-10 11:01:53 +00002120- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2121 menu entries were not deleted.
2122
Brett Cannon83e81842008-08-09 23:30:55 +00002123- Copied the implementation of reduce() to _functools.reduce() to have a
2124 version that did not raise a DeprecationWarning under -3.
2125
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002126- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2127 a MemoryError rather than silently stop the iteration.
2128
Guido van Rossum59ce9012008-08-09 14:55:34 +00002129- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2130 to _sre.compile() will now be rejected. This should not affect anybody
2131 since the re.compile() function never generates invalid re-bytecode.
2132
Skip Montanaroa032bf42008-08-08 22:52:51 +00002133- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2134 upon first access it can be automatically initialized from the csv file if
2135 it wasn't initialized during instantiation.
2136
Brett Cannon3aa2a492008-08-06 22:28:09 +00002137- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2138 the reload() built-in has been removed.
2139
Brett Cannon7e30b672008-08-04 21:52:25 +00002140- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002141 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2145 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2146 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

2149 raised an AttributeError.
2150
Benjamin Peterson01a24322008-07-28 23:35:27 +00002151- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002152 asking for a specific length. This problem only affected files opened
2153 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002154
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002155- Issue #3449: Update decimal module to use most recent specification
2156 (v. 1.68) and tests (v. 2.58) from IBM.
2157
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002158- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2166
2167- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2168 invalid arguments.
2169
2170- Issue #3302: Fix several crashes when calling locale's gettext functions
2171 with None arguments.
2172
2173- Issue #3389: Allow resolving dotted names for handlers in logging
2174 configuration files.
2175
2176- Deprecate the sunaudio module for removal in Python 3.0.
2177
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002178- Issue #3394: zipfile.writestr sets external attributes when passed a
2179 file name rather than a ZipInfo instance, so files are extracted with
2180 mode 0600 rather than 000 under Unix.
2181
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002182- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2183 argument in python 2.5, this broke code that subclassed Popen to include its
2184 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2193
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002194- Issue #2235: the C API function PyObject_HashNotImplemented and its
2195 interaction with the tp_hash slot (added in 2.6b2) are now documented
2196
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002197- Issue #643841: The language reference now provides more detailed
2198 coverage of the lookup process for special methods. The disclaimers
2199 regarding lack of coverage of new-style classes have also been
2200 removed, since the coverage is now fairly reasonable.

2209-----------------
2210
Georg Brandl3e483f62008-07-16 22:57:41 +00002211- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2212 its methods now allow for items objects that can be converted to
2213 an integer using operator.index().
2214
Mark Dickinson64b7e502008-07-16 09:40:03 +00002215- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2216 produced a ValueError instead of giving the correct float.
2217
Eric Smitha5fa5a22008-07-16 00:11:49 +00002218- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2219 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2220
Mark Dickinson7103aa42008-07-15 19:08:33 +00002221- Issue #3008: the float type has a new instance method 'float.hex'
2222 and a new class method 'float.fromhex' to convert floating-point
2223 numbers to and from hexadecimal strings, respectively.
2224
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002225- Issue #2235: __hash__ is once again inherited by default. To allow
2226 collections.Hashable to remain meaningful in the presence of the
2227 default hash implementation (object.__hash__), it is now possible
2228 to explicit block inheritance of hash by setting __hash__=None at
2229 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2230 level.
2231
Nick Coghlanb028f502008-07-13 14:52:36 +00002232- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2233 the parent module cannot be found while performing an absolute import.
2234 This means that an incorrectly defined __package__ attribute will
2235 now only prevent relative imports in that module rather than causing
2236 all imports from that module to fail.
2237
Nick Coghlan14ff9942008-07-08 14:21:42 +00002238- Issue #2517: Allow unicode messages in Exceptions again by correctly
2239 bypassing the instance dictionary when looking up __unicode__ on
2240 new-style classes.
2241
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002242- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2243 set to a custom object whose write() method happens to install
2244 another file in sys.stdout.

2248 another thread's dictionary.
2249
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002250- Issue #3004: Minor change to slice.indices(): the start and stop
2251 arguments are now treated identically, making the behaviour easier
2252 to describe and understand. For example, slice(None, -10,
2253 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2254 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2255 10, -1).
2256
Georg Brandl278fc502008-07-19 12:46:12 +00002257- Issue #3219: Calling a function with repeated keyword arguments,
2258 f(a=2, a=23), would not cause a syntax error. This was a regression
2259 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00002709 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002710
2711 This is controlled by the configure argument ``--with-universal-archs``:
2712
2713 - ``--with-universal-archs=all``: install 4-way universal
2714
2715 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2716
2717 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2718

2758 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00002759
Christian Heimese74c8f22008-04-19 02:23:57 +00002760- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002771- Issue #1631171: Re-implement the 'warnings' module in C (the
2772 original Python code has been kept as backup). This will allow for
2773 using the 'warning's machinery in such places as the parser where
2774 use of pure Python code is not possible. Both the ``showarning()``
2775 and ``formatwarning()`` gain an optional 'line' argument which is
2776 not called by default for backwards-compatibility reasons. Setting
2777 ``warnings.showwarning()`` to an implementation that lacks support
2778 for the ``line`` argument will raise a DeprecationWarning.

2802
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002803- The getpass module has been improved on Unix. It now uses /dev/tty
2804 by default and uses stderr instead of stdout. A GetPassWarning is
2805 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002806

Georg Brandl3ee81df2008-05-17 18:14:43 +00002820- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002821 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002841- Issue #2550: The approach used by client/server code for obtaining
2842 ports to listen on in network-oriented tests has been refined in an
2843 effort to facilitate running multiple instances of the entire
2844 regression test suite in parallel without issue.
2845 test_support.bind_port() has been fixed such that it will always
2846 return a unique port -- which wasn't always the case with the
2847 previous implementation, especially if socket options had been set
2848 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2849 new implementation of bind_port() will actually raise an exception
2850 if it is passed an AF_INET/SOCK_STREAM socket with either the
2851 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2852 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2853 the socket it's been passed. This currently only applies to
2854 Windows. This option prevents any other sockets from binding to the
2855 host/port we've bound to, thus removing the possibility of the
2856 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2857 when a second SOCK_STREAM socket binds and accepts to a host/port
2858 that's already been bound by another socket. The optional preferred
2859 port parameter to bind_port() has been removed. Under no
2860 circumstances should tests be hard coding ports!
2861
2862 test_support.find_unused_port() has also been introduced, which will
2863 pass a temporary socket object to bind_port() in order to obtain an
2864 unused port. The temporary socket object is then closed and
2865 deleted, and the port is returned. This method should only be used
2866 for obtaining an unused port in order to pass to an external program
2867 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2868 a parameter to a server-oriented class that doesn't give you direct
2869 access to the underlying socket used.
2870
2871 Finally, test_support.HOST has been introduced, which should be used
2872 for the host argument of any relevant socket calls (i.e. bind and
2873 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002874
2875 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002876 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002877 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2878 test_asynchat and test_socket_ssl.
2879
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880 It is now possible for multiple instances of the regression test
2881 suite to run in parallel without issue.

3149
Fred Drakea8ee94b2008-03-01 02:45:07 +00003150- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003151 644. The mode is now inherited from the py file.

3154
3155- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003156
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003157- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003158 issue 215555 for a discussion.
3159
Eric Smitha73fbe72008-02-23 03:09:44 +00003160- Added the future_builtins module, which contains hex() and oct().
3161 These are the PEP 3127 version of these functions, designed to be
3162 compatible with the hex() and oct() builtins from Python 3.0. They
3163 differ slightly in their output formats from the existing, unchanged
3164 Python 2.6 builtins. The expected usage of the future_builtins
3165 module is:
3166 from future_builtins import hex, oct
3167
Eric Smith7ef40bf2008-02-20 23:34:22 +00003168- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3169 exponents for exponents with absolute value < 100. Follows C99
3170 standard. This is a change on Windows, which would use 3 digits.
3171 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3172 so that any alterations it does to the resulting string will be
3173 available in stringlib/formatter.h (for float.__format__).
3174
Eric Smith5a3c1352008-02-19 13:21:56 +00003175- Implemented PEP 3101, Advanced String Formatting. This adds a new
3176 builtin format(); a format() method for str and unicode; a
3177 __format__() method to object, str, unicode, int, long, float, and
3178 datetime; the class string.Formatter; and the C API
3179 PyObject_Format().
3180
Georg Brandl3ee81df2008-05-17 18:14:43 +00003181- Fixed several potential crashes, all caused by specially crafted
3182 __del__ methods exploiting objects in temporarily inconsistent
3183 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003184
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003185- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003186 prevent a possible crash: an Abstract Base Class would try to access
3187 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003188

Georg Brandl3ee81df2008-05-17 18:14:43 +00003192- Clear all free lists during a gc.collect() of the highest generation
3193 in order to allow pymalloc to free more arenas. Python may give back
3194 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003195
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196- Issue #2045: Fix an infinite recursion triggered when printing a
3197 subclass of collections.defaultdict, if its default_factory is set
3198 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003199
Christian Heimesf75dbef2008-02-08 00:11:31 +00003200- Fixed a minor memory leak in dictobject.c. The content of the free
3201 list was not freed on interpreter shutdown.
3202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Limit free list of method and builtin function objects to 256
3204 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003205
Georg Brandl3ee81df2008-05-17 18:14:43 +00003206- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3207 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003208 to compact the internal free lists of pre-allocted ints and floats.
3209
Georg Brandl3ee81df2008-05-17 18:14:43 +00003210- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3211 calls. Python expected the return type int but the fork familie
3212 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003213
Georg Brandl3ee81df2008-05-17 18:14:43 +00003214- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3215 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003216

3224 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003225
Georg Brandl3ee81df2008-05-17 18:14:43 +00003226- Patch #1473257: generator objects gain a gi_code attribute. This is
3227 the same object as the func_code attribute of the function that
3228 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003229
Georg Brandl3ee81df2008-05-17 18:14:43 +00003230- Issue #1920: "while 0" statements were completely removed by the
3231 compiler, even in the presence of an "else" clause, which is
3232 supposed to be run when the condition is false. Now the compiler
3233 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003234
Guido van Rossumeead05f2008-01-24 18:21:02 +00003235- A few crashers fixed: weakref_in_del.py (issue #1377858);
3236 loosing_dict_ref.py (issue #1303614, test67.py);
3237 borrowed_ref_[34].py (not in tracker).
3238
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003239- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003240 suppressed while an extension is loaded by calling SetErrorMode in
3241 dynload_win.c. The error is still reported properly.
3242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003244 several extension methods and modules do not work without unicode
3245 support.
3246
Georg Brandl26543b12008-01-21 18:36:51 +00003247- Issue #1882: when compiling code from a string, encoding cookies in the
3248 second line of code were not always recognized correctly.
3249
Georg Brandl14404b62008-01-19 19:27:05 +00003250- Issue #1679: "0x" was taken as a valid integer literal.
3251
Georg Brandl6caad7d2008-01-26 14:19:22 +00003252- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003253 added.
3254
Christian Heimesc94e2b52008-01-14 04:13:37 +00003255- sys.float_info / PyFloat_GetInfo: The floating point information
3256 object was converted from a dict to a specialized structseq object.
3257
Georg Brandl3ee81df2008-05-17 18:14:43 +00003258- Patch #1816: Added sys.flags structseq. It exposes the status of
3259 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003260
Georg Brandl3ee81df2008-05-17 18:14:43 +00003261- Objects/structseq.c: Implemented new structseq representation. The
3262 patch makes structseqs (e.g. the return value of os.stat) more
3263 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003264
Georg Brandl3ee81df2008-05-17 18:14:43 +00003265- Patch #1700288: added a type attribute cache that caches method
3266 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003267

3274 envvar and sys.dont_write_bytecode attribute. All these can be set
3275 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003276
Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Improve some exception messages when Windows fails to load an
3278 extension module. Now we get for example '%1 is not a valid Win32
3279 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00003286- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003287 and INF. float("nan"), float("inf") and float("-inf") now work on
3288 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003289
Georg Brandl3ee81df2008-05-17 18:14:43 +00003290- Compiler now generates simpler and faster code for dictionary
3291 literals. The oparg for BUILD_MAP now indicates an estimated
3292 dictionary size. There is a new opcode, STORE_MAP, for adding
3293 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003341- Issue #1686386: Tuple's tp_repr did not take into account the
3342 possibility of having a self-referential tuple, which is possible
3343 from C code. Nor did object's tp_str consider that a type's tp_str
3344 could do something that could lead to an inifinite recursion.
3345 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3346 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003348- Issue #1164: It was possible to trigger deadlock when using the
3349 'print' statement to write to a file since the GIL was not released
3350 as needed. Now PyObject_Print() does the right thing along with
3351 various tp_print implementations of the built-in types and those in
3352 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003354- Issue #1147: Exceptions were directly allowing string exceptions in
3355 their throw() method even though string exceptions no longer
3356 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003357
Georg Brandl3ee81df2008-05-17 18:14:43 +00003358- Issue #1096: Prevent a segfault from getting the repr of a very
3359 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003360
Brett Cannon1e534b52007-09-07 04:18:30 +00003361- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003362 PyObject_Call() never calling back out to Python code to trigger
3363 recursion depth updates/checks. Required the creation of a static
3364 RuntimeError instance in case normalizing an exception put the
3365 recursion check value past its limit. Fixes crashers
3366 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003381- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003382 __*__ attributes. (Some already existed, e.g., __doc__ and
3383 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003384
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003385- Add -3 option to the interpreter to warn about features that are
3386 deprecated and will be changed/removed in Python 3.0.
3387
Georg Brandl2134e752007-05-21 20:34:16 +00003388- Patch #1686487: you can now pass any mapping after '**' in function
3389 calls.
3390
Collin Winter62903052007-05-18 23:11:24 +00003391- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392 "except E as target:". This is to provide forwards compatibility
3393 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003394
Brett Cannon229cee22007-05-05 01:34:02 +00003395- Deprecate BaseException.message as per PEP 352.
3396
Georg Brandl3ee81df2008-05-17 18:14:43 +00003397- Issue #1303614: don't expose object's __dict__ when the dict is

3399
Vinay Sajip8549ce32007-05-06 17:53:37 +00003400- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003401 setting a plain string, ie don't expand to single letter identifiers.
3402
Raymond Hettinger13936692007-04-11 18:40:58 +00003403- Request #1191699: Slices can now be pickled.
3404
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003405- Request #1193128: str.translate() now allows a None argument for
3406 translations that only remove characters without re-mapping the
3407 remaining characters.
3408
Georg Brandl5cb76c12007-03-21 09:00:39 +00003409- Patch #1682205: a TypeError while unpacking an iterable is no longer
3410 masked by a generic one with the message "unpack non-sequence".
3411
Neal Norwitzaa754b72007-03-21 06:39:48 +00003412- Remove unused file Python/fmod.c.
3413
Guido van Rossum143b5642007-03-23 04:58:42 +00003414- Bug #1683368: The object.__init__() and object.__new__() methods are
3415 now stricter in rejecting excess arguments. The only time when
3416 either allows excess arguments is when it is not overridden and the
3417 other one is. For backwards compatibility, when both are
3418 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003419 warning later). Also, type.__init__() insists on the same signature
3420 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003421
Georg Brandl3ee81df2008-05-17 18:14:43 +00003422- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3423 object to complex using its __complex__() method before falling back
3424 to the __float__() method. Therefore, the functions in the cmath
3425 module now can operate on objects that define a __complex__()
3426 method.

3443
Georg Brandl7b9c5552007-03-12 14:30:05 +00003444- Bug #1678647: write a newline after printing an exception in any
3445 case, even when converting the value to a string failed.
3446
Georg Brandl871f1bc2007-03-12 13:17:36 +00003447- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448 its argument, if it exists. If not, it will work like before. This
3449 allows customizing the output of dir() in the presence of a
3450 __getattr__().

3459 parthensized forms. This means complex(repr(x)) now works instead of
3460 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003461
Georg Brandlaa2321b2007-03-07 00:40:28 +00003462- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003463 makes the filenames the warning module prints much more sensible
3464 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003465

3467 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003468 variable is given, but break into the interactive interpreter just
3469 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003477- Patch #1674228: when assigning a slice (old-style), check for the
3478 sq_ass_slice instead of the sq_slice slot.
3479
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- When printing an unraisable error, don't print exceptions. before
3481 the name. This duplicates the behavior whening normally printing
3482 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003583 generator expressions (x for x, in ... ) works again. Fixing this
3584 problem required changing the .pyc magic number. This means that
3585 .pyc files generated before 2.5c2 will be regenerated.

4111 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004392- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4393 with RFC 3207 and forgets any knowledge obtained from the server not
4394 obtained from the TLS negotiation itself. Patch contributed by Bill
4395 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004396
Georg Brandl3ee81df2008-05-17 18:14:43 +00004397- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004398 that the SMTP.starttls() caller no longer needs to call ehlo()
4399 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004400 does not claim to support starttls. Adds the
4401 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4402 Fenner.

4482 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4483 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004500 time so that opening a database previously created with the DB_DUP
4501 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4502 opens. Specifically: dictionary assignment to a DB object will
4503 replace all values for a given key when the database allows
4504 duplicate values. DB users should use DB.put(k, v) when they want
4505 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004506

4512 characters with ASCII value less than 32. Also, it correctly quotes
4513 dots only if they occur on a single line, as opposed to the previous
4514 behavior of quoting dots if they are the second character of any
4515 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004516

4838-----
4839
Georg Brandl3ee81df2008-05-17 18:14:43 +00004840- Unified naming convention for free lists and their limits. All free
4841 lists in Object/ are named ``free_list``, the counter ``numfree``
4842 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4843 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004844
Georg Brandl3ee81df2008-05-17 18:14:43 +00004845- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4846 to ``PyTuple_SetItem``, it can be used to populate a brand new
4847 frozenset; but it does not steal a reference to the added item.

4852 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4853 PyLong_FromSsize_t public functions.

4856
4857- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4858 ``PyFloat_GetInfo()`` to the float API.
4859
Georg Brandl3ee81df2008-05-17 18:14:43 +00004860- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4861 of w# format code incorrectly truncated the length to an int, even
4862 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4863 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004864
Georg Brandl3ee81df2008-05-17 18:14:43 +00004865- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4883- Fix some leftovers from the conversion from int to Py_ssize_t
4884 (relevant to strings and sequences of more than 2**31 items).
4885
4886- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4887 outside of pystate.c and should not be necessary.
4888
Georg Brandl3ee81df2008-05-17 18:14:43 +00004889- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4890 absolute imports. In earlier versions they might have used relative
4891 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004892
Georg Brandl3ee81df2008-05-17 18:14:43 +00004893- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4894 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004895
Georg Brandl3ee81df2008-05-17 18:14:43 +00004896- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004903- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4904 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4905 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4906 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004907

Georg Brandl3ee81df2008-05-17 18:14:43 +00004921- Removed the macfs module. It had been deprecated since Python 2.5.
4922 This lead to the deprecation of macostools.touched() as it relied
4923 solely on macfs and was a no-op under OS X.
