12Core and Builtins
13-----------------
14
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000015- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
16 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
17
Mark Dickinson1b34d252010-01-01 17:27:30 +000018- Issue #5080: A number of functions and methods previously produced a
19 DeprecationWarning when passed a float argument where an integer was
20 expected. These functions and methods now raise TypeError instead.
21 The majority of the effects of this change are in the extension
22 modules, but some core functions and methods are affected: notably
23 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
24 methods.
25
Benjamin Peterson0f02d392009-12-30 19:34:10 +000026- Issue #7604: Deleting an unset slotted attribute did not raise an
27 AttributeError.
28
Mark Dickinson99d652e2009-12-30 12:12:23 +000029- Issue #7534: Fix handling of IEEE specials (infinities, nans,
30 negative zero) in ** operator. The behaviour now conforms to that
31 described in C99 Annex F.
32
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000033- Issue #7579: the msvcrt module now has docstrings for all its functions.
34
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000035- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
36 used to drop the time part of the result.
37
Mark Dickinson46572832009-12-27 14:55:57 +000038- Issue #1811: improve accuracy and cross-platform consistency for
39 true division of integers: the result of a/b is now correctly
40 rounded for ints a and b (at least on IEEE 754 platforms), and in
41 particular does not depend on the internal representation of a long.
42
Ezio Melottif84caf42009-12-24 22:25:17 +000043- Issue #6108: unicode(exception) and str(exception) should return the same
44 message when only __str__ (and not __unicode__) is overridden in the subclass.
45
Ronald Oussoren92919a62009-12-24 13:30:58 +000046- Issue #6834: replace the implementation for the 'python' and 'pythonw'
47 executables on OSX.
48
49 These executables now work properly with the arch(1) command:
50 ``arch -ppc python`` will start a universal binary version of python
51 in PPC mode (unlike previous releases).
52
R. David Murray0a0a1a82009-12-14 16:28:26 +000053- Issue #1680159: unicode coercion during an 'in' operation no longer masks
54 the underlying error when the coercion fails for the left hand operand.
55
Benjamin Peterson4895af42009-12-13 16:36:53 +000056- Issue #7491: Metaclass's __cmp__ method was ignored.
57
Antoine Pitrou2a08b422009-12-13 16:18:14 +000058- Issue #7466: segmentation fault when the garbage collector is called
59 in the middle of populating a tuple. Patch by Florent Xicluna.
60
R. David Murrayc7298ff2009-12-14 21:57:39 +000061

Tarek Ziadé0479eb52009-12-21 23:37:44 +000073- Issue #7556: Distutils' msvc9compiler now opens the MSVC Manifest
74 file in text mode.
75
Tarek Ziadé2421d562009-12-20 23:23:34 +000076- Issue #7552: Removed line feed in the base64 Authorization header in
77 the Distutils upload command to avoid an error when PyPI reads it.
78 This occurs on long passwords. Initial patch by JP St. Pierre.
79
80- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +000081 Patch by Tatsuhiro Tsujikawa.
82
Benjamin Petersonddd392c2009-12-13 19:19:07 +000083- Issue #7349: Make methods of file objects in the io module accept None as an
84 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
85 the same as passing no argument.
86
Benjamin Petersonc4771d22009-12-13 17:31:31 +000087- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
88 like other file objects.
89
Lars Gustäbel92ca7562009-12-13 11:32:27 +000090- Issue #7357: tarfile no longer suppresses fatal extraction errors by

108 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
109 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
110 arguments for integer format codes (other than 'L'): previously an
111 attempt to pass a float resulted in a DeprecationWarning; now it
112 gives a TypeError. For the 'L' format code (which previously had no
113 warning) there is now a DeprecationWarning.
114

Benjamin Peterson2c196742009-12-31 03:17:18 +0000125- Issue #7609: Add a --with-system-expat option that causes the system's expat
126 library to be used for the pyexpat module instead of the one included with
127 Python.
128

155Core and Builtins
156-----------------
157
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000158- Issue #7419: setlocale() could crash the interpreter on Windows when called
159 with invalid values.
160
Eric Smithc4ab8332009-11-29 17:40:57 +0000161- Issue #3382: 'F' formatting for float and complex now convert the
162 result to upper case. This only affects 'inf' and 'nan', since 'f'
163 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000164
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000165- Remove switch from "%f" formatting to "%g" formatting for floats
166 larger than 1e50 in absolute value.
167
Mark Dickinson18cfada2009-11-23 18:46:41 +0000168- Remove restrictions on precision when formatting floats. E.g.,
169 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
170 requested 120 significant digits instead.
171
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000172- Add Py3k warnings for parameter names in parenthesis.
173
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000174- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000175
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000176- Issue #7085: Fix crash when importing some extensions in a thread
177 on MacOSX 10.6.
178
Mark Dickinsonb678de82009-11-19 18:41:49 +0000179- Issue #7117: repr(x) for a float x returns a result based on the
180 shortest decimal string that's guaranteed to round back to x under
181 correct rounding (with round-half-to-even rounding mode).
182 Previously it gave a string based on rounding x to 17 decimal digits.
183 repr(x) for a complex number behaves similarly. On platforms where
184 the correctly-rounded strtod and dtoa code is not supported (see below),
185 repr is unchanged.
186
187- Issue #7117: On almost all platforms: float-to-string and
188 string-to-float conversions within Python are now correctly rounded.
189 Places these conversions occur include: str for floats and complex
190 numbers; the float and complex constructors; old-style and new-style
191 numeric formatting; serialization and deserialization of floats and
192 complex numbers using marshal, pickle and json; parsing of float and
193 imaginary literals in Python code; Decimal-to-float conversion.
194
195 The conversions use a Python-adapted version of David Gay's
196 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
197 functions. This code is supported on Windows, and on Unix-like
198 platforms using gcc, icc or suncc as the C compiler. There may be a
199 small number of platforms on which correct operation of this code
200 cannot be guaranteed, so the code is not used: notably, this applies
201 to platforms where the C double format is not IEEE 754 binary64, and
202 to platforms on x86 hardware where the x87 FPU is set to 64-bit
203 precision and Python's configure script is unable to determine how
204 to change the FPU precision. On these platforms conversions use the
205 platform strtod and dtoa, as before.
206
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000207- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000208 now uses the correctly-rounded string <-> float conversions
209 described above (when available), and so produces correctly rounded
210 results that will display nicely under the float repr. There are
211 two related small changes: (1) round now accepts any class with an
212 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000213 floats for the second argument), and (2) an excessively large second
214 integer argument (e.g., round(1.234, 10**100)) no longer raises an
215 exception.
216
Philip Jenveyfab8be22009-11-17 02:42:26 +0000217- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
218
Benjamin Petersone36199b2009-11-12 23:39:44 +0000219- Fix several issues with compile(). The input can now contain Windows and Mac
220 newlines and is no longer required to end in a newline.
221
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000222- Remove length limitation when constructing a complex number from a
223 unicode string.
224
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000225- Issue #7244: itertools.izip_longest() no longer ignores exceptions
226 raised during the formation of an output tuple.
227

229
Antoine Pitrouefb60c02009-10-20 21:29:37 +0000230- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

232 interpreter is killed. Patch by Adam Olsen.
233
Eric Smithc12781a2009-10-19 14:38:14 +0000234- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

239
Benjamin Peterson196b0922009-10-15 15:44:46 +0000240- Issue #7140: The __dict__ of a module should not be cleared unless the module
241 is the only object holding a reference to it.
242
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +0000243- Issue #1754094: Improve the stack depth calculation in the compiler.
244 There should be no other effect than a small decrease in memory use.
245 Patch by Christopher Tur Lesniewski-Laas.
246
Antoine Pitroubeaf6a02009-10-11 21:03:26 +0000247- Issue #7084: Fix a (very unlikely) crash when printing a list from one

Mark Dickinson2f865b92009-06-30 15:32:30 +0000310- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
311 This fixes a build failure on HP-UX: int32_t and uint32_t are
312 defined in inttypes.h instead of stdint.h on that platform.
313
Hirokazu Yamamotoa3c56092009-06-28 10:23:00 +0000314- Issue #4856: Remove checks for win NT.

320
Raymond Hettinger62641e92009-06-23 20:59:43 +0000321- Issue #6329: Fixed iteration for memoryview objects (it was being blocked
322 because it wasn't recognized as a sequence).
323
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +0000324- Issue #6289: Encoding errors from compile() were being masked.
325
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000326- When no module is given in a relative import, the module field of the
327 ImportFrom AST node is now None instead of an empty string.
328
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000329- Assignment to None using import statements now raises a SyntaxError.
330
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +0000331- Issue #4547: When debugging a very large function, it was not always
332 possible to update the lineno attribute of the current frame.
333
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000334- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000335 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000336
Raymond Hettinger578a2282009-05-29 04:58:52 +0000337- Issue #5982: staticmethod and classmethod now expose the wrapped
338 function with __func__.
339
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000340- Added support for multiple context managers in the same with-statement.
341 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +0000342
Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000343- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
344 statement and correctly lookup the __enter__ and __exit__ special methods.
345
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000346- Issue #5829: complex("1e500") no longer raises OverflowError. This
347 makes it consistent with float("1e500") and interpretation of real
348 and imaginary literals.
349
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000350- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
351
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000352- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
353 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000354
R. David Murray525cffc2009-05-13 13:07:14 +0000355- Issue #5994: the marshal module now has docstrings.
356
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000357- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
358 (1) inf and nan strings with trailing whitespace were incorrectly
359 rejected; (2) parsing of strings representing infinities and nans
360 was locale aware; and (3) the interpretation of fromhex('-nan')
361 didn't match that of float('-nan').
362
Eric Smitha985a3a2009-05-05 18:26:08 +0000363- Issue #5920: For float.__format__, change the behavior with the
364 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
365 to be like 'g' but with at least one decimal point and with a
366 default precision of 12. Previously, the behavior the same but with
367 a default precision of 6. This more closely matches str(), and
368 reduces surprises when adding alignment flags to the empty
369 presentation type. This also affects the new complex.__format__ in
370 the same way.
371
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000372- Issue #5890: in subclasses of 'property' the __doc__ attribute was
373 shadowed by classtype's, even if it was None. property now
374 inserts the __doc__ into the subclass instance __dict__.
375
Antoine Pitrou653dece2009-05-04 18:32:32 +0000376- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
377 sequences. Patch by Nick Barnes and Victor Stinner.
378
Vinay Sajipf9b01fe2009-05-09 12:07:17 +0000379- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +0000380 format(complex(1, 2./3), '.5') now produces a sensible result.
381
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000382- Issue #5864: Fix empty format code formatting for floats so that it
383 never gives more than the requested number of significant digits.
384
Eric Smithcac7af62009-04-27 19:04:37 +0000385- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
386 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
387

389 titlecase, but not their own uppercase.
390
Eric Smith068f0652009-04-25 21:40:15 +0000391- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
392 _PyOS_double_to_string or PyOS_double_to_string.
393
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000394- Issue #5283: Setting __class__ in __del__ caused a segfault.
395
Mark Dickinson95bc9802009-04-24 12:46:53 +0000396- Issue #5816: complex(repr(z)) now recovers z exactly, even when
397 z involves nans, infs or negative zeros.
398
Eric Smithaca19e62009-04-22 13:29:05 +0000399- Implement PEP 378, Format Specifier for Thousands Separator, for
400 floats, ints, and longs.
401
402- Issue #5515: 'n' formatting for ints, longs, and floats handles
403 leading zero formatting poorly.
404
405- Issue #5772: For float.__format__, don't add a trailing ".0" if
406 we're using no type code and we have an exponent.
407
Mark Dickinson6736cf82009-04-20 21:13:33 +0000408- Issue #3166: Make long -> float (and int -> float) conversions
409 correctly rounded.
410
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000411- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
412 some builtin types.
413
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000414- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000415 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000416
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000417- Issue #5759: float() didn't call __float__ on str subclasses.
418
Georg Brandl3c4a5462009-04-12 12:08:12 +0000419- Issue #5704: the "-3" command-line option now implies "-t".
420
R. David Murray0374a822009-04-09 21:54:50 +0000421- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
422 its clarity and its speed.
423
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000424- Issue #2396: the memoryview object was backported from Python 3.1.
425

430
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000431- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
432 the end sys.path, for compatibility with the system install of Python.
433
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000434- Issue #4688: Add a heuristic so that tuples and dicts containing only
435 untrackable objects are not tracked by the garbage collector. This can
436 reduce the size of collections and therefore the garbage collection overhead
437 on long-running programs, depending on their particular use of datatypes.
438
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000439- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
440 improve its performance. Long divisions and remainder operations
441 are now between 50% and 150% faster.
442
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000443- Issue #4258: Make it possible to use base 2**30 instead of base
444 2**15 for the internal representation of integers, for performance
445 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
446 --enable-big-digits option to configure, which overrides the
447 default. Add sys.long_info structseq to provide information about
448 the internal format.
449
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000450- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
451 result traceback.__members__ no longer exists.)
452
Mark Dickinson6b265f12009-03-18 16:07:26 +0000453- Issue #4474: PyUnicode_FromWideChar now converts characters outside
454 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
455 and sizeof(Py_UNICODE) == 2.
456
Eric Smith6f42edb2009-03-14 11:57:26 +0000457- Issue #5237: Allow auto-numbered fields in str.format(). For
458 example: '{} {}'.format(1, 2) == '1 2'.
459
Brett Cannon6c4cff02009-03-11 04:51:06 +0000460- Issue #3652: Make the 'line' argument for warnings.showwarning() a
461 requirement. Means the DeprecationWarning from Python 2.6 can go away.
462
Eric Smithe9fb6862009-02-20 14:02:36 +0000463- Issue #5247: Improve error message when unknown format codes are
464 used when using str.format() with str, unicode, long, int, and
465 float arguments.
466
Raymond Hettinger08259e82009-02-18 23:10:19 +0000467- Running Python with the -3 option now also warns about classic division
468 for ints and longs.
469
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000470- Issue #5260: Long integers now consume less memory: average
471 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
472 on a 64-bit system.
473
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000474- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
475 rotating the object pointer by 4 bits to the right.
476
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000477- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
478 it now forces its argument to double before testing for infinity.
479
Benjamin Petersone18ef192009-01-20 14:21:16 +0000480- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
481
Georg Brandl29c6a282009-04-05 20:23:13 +0000482- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000483 were suppressing all exceptions. These include list(), filter(), map(),
484 zip(), and bytearray().
485
Benjamin Peterson596d3062009-01-19 15:42:23 +0000486- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
487 functions.
488
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000489- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
490 OSError.
491

493
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000494- Issue #4935: The overflow checking code in the expandtabs() method common
495 to str, bytes and bytearray could be optimized away by the compiler, letting
496 the interpreter segfault instead of raising an error.
497
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000498- Issue #3720: Fix a crash when an iterator modifies its class and removes its
499 __next__ method.
500
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000501- Issue #4893: Use NT threading on CE.

504
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000505- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
506 collecting the oldest generation) so that allocating lots of objects without
507 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000508 Martin von Löwis at
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000509 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.

512
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000513- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
514 an existing .py counterpart, override the co_filename attributes of all
515 code objects if the original filename is obsolete (which can happen if the
516 file has been renamed, moved, or if it is accessed through different paths).
517 Patch by Ziga Seilnacht and Jean-Paul Calderone.
518
Martin v. Löwis5344c992009-01-02 20:32:55 +0000519- Issue #4075: Use OutputDebugStringW in Py_FatalError.
520
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000521- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
522 file with `str' filename on Windows.

525 did not get collected.
526
Nick Coghlan180e4002008-12-30 01:18:48 +0000527- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
528 where the tp_hash and tp_dict slots are both NULL.
529
Benjamin Peterson7af65562008-12-29 17:56:58 +0000530- Issue #4764: With io.open, IOError.filename is set when trying to open a
531 directory on POSIX systems.
532
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000533- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

538
Skip Montanarof205c132008-12-23 03:30:15 +0000539- Added test case to ensure attempts to read from a file opened for writing
540 fail.
541
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000542- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
543 print elapsed times, not only when some objects are uncollectable /
544 unreachable. Original patch by Neil Schemenauer.
545
Mark Dickinson1a707982008-12-17 16:14:37 +0000546- Issue #3439: Add a bit_length method to int and long.

550
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000551- Issue #4597: Fixed exception handling when the __exit__ function of a
552 context manager returns a value that cannot be converted to a bool.
553
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000554- Issue #4597: Fixed several opcodes that weren't always propagating
555 exceptions.
556
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000557- Issue #4445: Replace "sizeof(PyStringObject)" with
558 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
559 str instances. On a typical machine this saves 3 bytes of memory
560 (on average) per string allocation.
561
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000562- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
563 interpreter to abort ("Fatal Python error: Could not reset the stack!")
564 instead of throwing a MemoryError.
565
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000566- Issue #3689: The list reversed iterator now supports __length_hint__
567 instead of __len__. Behavior now matches other reversed iterators.
568
Benjamin Petersonc078f922008-11-21 22:27:24 +0000569- Issue #4367: Python would segfault during compiling when the unicodedata
570 module couldn't be imported and \N escapes were present.
571
Vinay Sajip213faca2008-12-03 23:22:58 +0000572- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000573 method on file objects with closefd=False. The file descriptor is still
574 kept open but the file object behaves like a closed file. The ``FileIO``
575 object also got a new readonly attribute ``closefd``.
576
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000577- Issue #4348: Some bytearray methods returned that didn't cause any change to
578 the bytearray, returned the same bytearray instead of a copy.
579
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000580- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

587 exec statement.
588
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000589- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
590 method does not return iterators for the 4th and 5th items.
591
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000592- Issue #4209: Enabling unicode_literals and the print_function in the same
593 __future__ import didn't work.
594
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000595- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000596 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000597
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000598- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
599 returned a path longer than MAX_PATH. (But It's doubtful this code path is
600 really executed because I cannot move to such directory on win2k)

Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000602- Issue #4069: When set.remove(element) is used with a set element, the element
603 is temporarily replaced with an equivalent frozenset. But the eventual
604 KeyError would always report the empty frozenset([]) as the missing key. Now
605 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000625- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
626 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
627 step. This avoids problems with counting UTF-8 bytes that ignores the effect
628 of using the replace error handler in PyUnicode_DecodeUTF8().
629
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000630- Issue #3739: The unicode-internal encoder now reports the number of characters

632
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000633- Issue #2422: When compiled with the ``--with-valgrind`` option, the

635 Valgrind. This gives improved memory leak detection when running
636 under Valgrind, while taking advantage of pymalloc at other times.

1873 leak-chasing test runs give sensible results. The previous method of
1874 reaping threads could return successfully while some Thread objects were

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00001997 AttributeError instead of RuntimeError, depending in which C API call
1998 exactly the recursion limit is exceeded. Consequently, both exception types

2015
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002016- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2017
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002018- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2019 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2020 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2021 ``printf`` function, whereas PyString_FromFormat has an independent
2022 implementation and uses "%zd" on all platforms for size_t values.
2023 This makes a difference on win64, where ``printf`` needs "%Id" to display
2024 64bit values.
2025
Benjamin Peterson97179b02008-09-09 20:55:01 +00002026- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2027 error.
2028
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002029- Issue #3777: long() applied to a float object now always return a long
2030 object; previously an int would be returned for small values. the __long__
2031 method is allowed to return either an int or a long, but the behaviour of
2032 float objects should not change to respect backward compatibility.
2033
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002034- Issue #3751: str.rpartition would perform a left-partition when called with
2035 a unicode argument.
2036
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002037- Issue #3683: Fix compilation when --without-threads is given.
2038
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002039- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002040 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002041 was correctly parsed but parsing of subsequent arguments failed.
2042
Vinay Sajip35e3b032008-09-01 14:33:59 +00002043- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002044 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2045 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2046 when given a tuple of classes as second argument, were looking up
2047 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2048 type object.
2049
Neal Norwitz18aa3882008-08-24 05:04:52 +00002050- Fix crashes on memory allocation failure found with failmalloc.
2051
2052- Fix memory leaks found with valgrind and update suppressions file.
2053
2054- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2055
2056- Fix problem using wrong name in decimal module reported by pychecker.
2057
Christian Heimes7d4c3172008-08-22 19:47:25 +00002058- Silenced another compiler warning about a used but not defined
2059 function 'stringlib_contains_obj'.

2062 ``__delslice__``.
2063
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002064- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2065 library targets in the Makefile.
2066
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002067- Issue #1204: The configure script now tests for additional libraries
2068 that may be required when linking against readline. This fixes issues
2069 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00002092- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002093 return a list or None rather than a custom object.
2094
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002095- Issue #1638033: Cookie.Morsel gained the httponly attribute.

2119 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2120 for catch_warnings() also led to an improvement in the raising of a
2121 DeprecationWarning related to warnings.warn_explicit().
2122
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002123- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002191
2192Core and Builtins
2193-----------------
2194
Guido van Rossumf8402962008-08-20 15:01:50 +00002195- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2196 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2197 extensions do not automatically benefit from the class attribute
2198 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2199 to their tp_flags field if they care. This is a backwards
2200 compatibility feature; in 3.0, all types will use the cache by
2201 default.
2202
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002203- Keyword arguments can now follow starred arguments. (``f(a, *args,
2204 keyword=23)`` is now valid syntax.)
2205
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002206- ctypes function pointers that are COM methods have a boolean True
2207 value again.
2208
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002209- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2210 by denying s# to parse objects that have a releasebuffer procedure,
2211 and introducing s*.
2212
Georg Brandl1e13ea92008-08-11 09:07:59 +00002213- Issue #3537: Fix an assertion failure when an empty but presized dict
2214 object was stored in the freelist.
2215
Mark Dickinsonb6467572008-08-04 21:30:09 +00002216- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2217 ValueError consistently across platforms.
2218
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002219- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2220 (64bit Unix, for example), unichr() would truncate its argument and return
2221 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2222
Neal Norwitze7d8be82008-07-31 17:17:14 +00002223- Apply security patches from Apple.
2224
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002225- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2226 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2227
Antoine Pitrou92f82162008-07-25 22:22:08 +00002228- Issue #1819: function calls with several named parameters are now on
2229 average 35% faster (as measured by pybench).
2230
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002231- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2232 the python debugger steps into a class statement: the free variables (local
2233 variables defined in an outer scope) would be deleted from the outer scope.
2234
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002235- Issue #2620: Overflow checking when allocating or reallocating memory
2236 was not always being done properly in some python types and extension
2237 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2238 all been updated to perform better checks and places in the code that
2239 would previously leak memory on the error path when such an allocation
2240 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002245- Issue #3612: Added some missing basic types in ctypes.wintypes.
2246
Benjamin Petersone977ad42008-08-20 01:42:01 +00002247- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2248 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2249
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002250- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2251 version reported by these tools does not necessarily follow the python
2252 version numbering scheme, so the module is less strict when parsing it.
2253
Nick Coghlanf70385a2008-08-18 12:42:46 +00002254- Issue #2235: Added Py3k warnings for types which will become unhashable
2255 under the stricter __hash__ inheritance rules in 3.0. Several types
2256 which did not meet the rules for hash invariants and were already
2257 unhashable in 3.0 have now been explicitly flagged as unhashable in
2258 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2259 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2260
Brett Cannon88f801d2008-08-18 00:46:22 +00002261- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2262 imported into the module but exposed as part of the module's API.
2263
Brett Cannon7b96f072008-08-18 00:41:11 +00002264- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2265
Brett Cannon46225e72008-08-18 00:36:52 +00002266- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2387-----------------
2388
Georg Brandl3e483f62008-07-16 22:57:41 +00002389- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2390 its methods now allow for items objects that can be converted to
2391 an integer using operator.index().
2392
Mark Dickinson64b7e502008-07-16 09:40:03 +00002393- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2394 produced a ValueError instead of giving the correct float.
2395
Eric Smitha5fa5a22008-07-16 00:11:49 +00002396- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2397 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2398
Mark Dickinson7103aa42008-07-15 19:08:33 +00002399- Issue #3008: the float type has a new instance method 'float.hex'
2400 and a new class method 'float.fromhex' to convert floating-point
2401 numbers to and from hexadecimal strings, respectively.
2402
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002403- Issue #2235: __hash__ is once again inherited by default. To allow
2404 collections.Hashable to remain meaningful in the presence of the
2405 default hash implementation (object.__hash__), it is now possible
2406 to explicit block inheritance of hash by setting __hash__=None at
2407 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2408 level.
2409
Nick Coghlanb028f502008-07-13 14:52:36 +00002410- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2411 the parent module cannot be found while performing an absolute import.
2412 This means that an incorrectly defined __package__ attribute will
2413 now only prevent relative imports in that module rather than causing
2414 all imports from that module to fail.
2415
Nick Coghlan14ff9942008-07-08 14:21:42 +00002416- Issue #2517: Allow unicode messages in Exceptions again by correctly

2426 another thread's dictionary.
2427
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002428- Issue #3004: Minor change to slice.indices(): the start and stop
2429 arguments are now treated identically, making the behaviour easier
2430 to describe and understand. For example, slice(None, -10,
2431 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2432 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2433 10, -1).
2434
Georg Brandl278fc502008-07-19 12:46:12 +00002435- Issue #3219: Calling a function with repeated keyword arguments,
2436 f(a=2, a=23), would not cause a syntax error. This was a regression
2437 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002439- Issue #2862: Make int and float freelist management consistent with
2440 other freelists. Changes their CompactFreeList apis into

2448 error when they failed.
2449
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002450- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002475- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2476 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002477 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002478 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002494- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002885- On MacOS X it is now possible to install the framework in 64-bit
2886 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002887 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002888
2889 This is controlled by the configure argument ``--with-universal-archs``:
2890
2891 - ``--with-universal-archs=all``: install 4-way universal
2892
2893 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2894
2895 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2896
2897 This option should be used in combination with ``--enable-universalsdk=``.
2898
2899 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002949- Issue #1631171: Re-implement the 'warnings' module in C (the
2950 original Python code has been kept as backup). This will allow for
2951 using the 'warning's machinery in such places as the parser where
2952 use of pure Python code is not possible. Both the ``showarning()``
2953 and ``formatwarning()`` gain an optional 'line' argument which is
2954 not called by default for backwards-compatibility reasons. Setting
2955 ``warnings.showwarning()`` to an implementation that lacks support
2956 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002999 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003019- Issue #2550: The approach used by client/server code for obtaining
3020 ports to listen on in network-oriented tests has been refined in an
3021 effort to facilitate running multiple instances of the entire
3022 regression test suite in parallel without issue.
3023 test_support.bind_port() has been fixed such that it will always
3024 return a unique port -- which wasn't always the case with the
3025 previous implementation, especially if socket options had been set
3026 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3027 new implementation of bind_port() will actually raise an exception
3028 if it is passed an AF_INET/SOCK_STREAM socket with either the
3029 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3030 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3031 the socket it's been passed. This currently only applies to
3032 Windows. This option prevents any other sockets from binding to the
3033 host/port we've bound to, thus removing the possibility of the
3034 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3035 when a second SOCK_STREAM socket binds and accepts to a host/port
3036 that's already been bound by another socket. The optional preferred
3037 port parameter to bind_port() has been removed. Under no
3038 circumstances should tests be hard coding ports!
3039
3040 test_support.find_unused_port() has also been introduced, which will
3041 pass a temporary socket object to bind_port() in order to obtain an
3042 unused port. The temporary socket object is then closed and
3043 deleted, and the port is returned. This method should only be used
3044 for obtaining an unused port in order to pass to an external program
3045 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3046 a parameter to a server-oriented class that doesn't give you direct
3047 access to the underlying socket used.
3048
3049 Finally, test_support.HOST has been introduced, which should be used
3050 for the host argument of any relevant socket calls (i.e. bind and
3051 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003052
3053 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003054 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003055 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3056 test_asynchat and test_socket_ssl.
3057
Georg Brandl3ee81df2008-05-17 18:14:43 +00003058 It is now possible for multiple instances of the regression test
3059 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003114 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3115 Plane. This affected raw unicode literals and the
3116 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3117 this case, like normal unicode literals and the 'unicode-escape'
3118 codec.

3327
Fred Drakea8ee94b2008-03-01 02:45:07 +00003328- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003329 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003334
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003335- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003336 issue 215555 for a discussion.
3337
Eric Smitha73fbe72008-02-23 03:09:44 +00003338- Added the future_builtins module, which contains hex() and oct().
3339 These are the PEP 3127 version of these functions, designed to be
3340 compatible with the hex() and oct() builtins from Python 3.0. They
3341 differ slightly in their output formats from the existing, unchanged
3342 Python 2.6 builtins. The expected usage of the future_builtins
3343 module is:
3344 from future_builtins import hex, oct
3345
Eric Smith7ef40bf2008-02-20 23:34:22 +00003346- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3347 exponents for exponents with absolute value < 100. Follows C99
3348 standard. This is a change on Windows, which would use 3 digits.
3349 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3350 so that any alterations it does to the resulting string will be
3351 available in stringlib/formatter.h (for float.__format__).
3352
Eric Smith5a3c1352008-02-19 13:21:56 +00003353- Implemented PEP 3101, Advanced String Formatting. This adds a new
3354 builtin format(); a format() method for str and unicode; a
3355 __format__() method to object, str, unicode, int, long, float, and
3356 datetime; the class string.Formatter; and the C API
3357 PyObject_Format().
3358
Georg Brandl3ee81df2008-05-17 18:14:43 +00003359- Fixed several potential crashes, all caused by specially crafted
3360 __del__ methods exploiting objects in temporarily inconsistent
3361 state.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003363- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003364 prevent a possible crash: an Abstract Base Class would try to access
3365 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003366
Georg Brandl3ee81df2008-05-17 18:14:43 +00003367- Fixed repr() and str() of complex numbers with infinity or nan as
3368 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003369
Georg Brandl3ee81df2008-05-17 18:14:43 +00003370- Clear all free lists during a gc.collect() of the highest generation
3371 in order to allow pymalloc to free more arenas. Python may give back
3372 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003373
Georg Brandl3ee81df2008-05-17 18:14:43 +00003374- Issue #2045: Fix an infinite recursion triggered when printing a
3375 subclass of collections.defaultdict, if its default_factory is set
3376 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003377
Christian Heimesf75dbef2008-02-08 00:11:31 +00003378- Fixed a minor memory leak in dictobject.c. The content of the free
3379 list was not freed on interpreter shutdown.
3380
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381- Limit free list of method and builtin function objects to 256
3382 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3385 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003386 to compact the internal free lists of pre-allocted ints and floats.
3387
Georg Brandl3ee81df2008-05-17 18:14:43 +00003388- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3389 calls. Python expected the return type int but the fork familie
3390 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003391
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3393 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003394
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3396 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003397
Georg Brandl3ee81df2008-05-17 18:14:43 +00003398- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3399 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003404- Patch #1473257: generator objects gain a gi_code attribute. This is
3405 the same object as the func_code attribute of the function that
3406 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003407
Georg Brandl3ee81df2008-05-17 18:14:43 +00003408- Issue #1920: "while 0" statements were completely removed by the
3409 compiler, even in the presence of an "else" clause, which is
3410 supposed to be run when the condition is false. Now the compiler
3411 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003412
Guido van Rossumeead05f2008-01-24 18:21:02 +00003413- A few crashers fixed: weakref_in_del.py (issue #1377858);
3414 loosing_dict_ref.py (issue #1303614, test67.py);
3415 borrowed_ref_[34].py (not in tracker).
3416
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003417- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003418 suppressed while an extension is loaded by calling SetErrorMode in
3419 dynload_win.c. The error is still reported properly.
3420
Georg Brandl3ee81df2008-05-17 18:14:43 +00003421- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003422 several extension methods and modules do not work without unicode
3423 support.
3424
Georg Brandl26543b12008-01-21 18:36:51 +00003425- Issue #1882: when compiling code from a string, encoding cookies in the
3426 second line of code were not always recognized correctly.
3427
Georg Brandl14404b62008-01-19 19:27:05 +00003428- Issue #1679: "0x" was taken as a valid integer literal.
3429
Georg Brandl6caad7d2008-01-26 14:19:22 +00003430- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003431 added.
3432
Christian Heimesc94e2b52008-01-14 04:13:37 +00003433- sys.float_info / PyFloat_GetInfo: The floating point information
3434 object was converted from a dict to a specialized structseq object.
3435
Georg Brandl3ee81df2008-05-17 18:14:43 +00003436- Patch #1816: Added sys.flags structseq. It exposes the status of
3437 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003438
Georg Brandl3ee81df2008-05-17 18:14:43 +00003439- Objects/structseq.c: Implemented new structseq representation. The
3440 patch makes structseqs (e.g. the return value of os.stat) more
3441 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003442
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443- Patch #1700288: added a type attribute cache that caches method
3444 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003445
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003446- Bug #1776: __import__() no longer accepts filenames on any platform.
3447 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003448
Georg Brandlaed6c662008-01-07 17:25:53 +00003449- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3452 envvar and sys.dont_write_bytecode attribute. All these can be set
3453 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003454
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455- Improve some exception messages when Windows fails to load an
3456 extension module. Now we get for example '%1 is not a valid Win32
3457 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003458

Christian Heimes0a8143f2007-12-18 23:22:54 +00003464- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465 and INF. float("nan"), float("inf") and float("-inf") now work on
3466 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003467
Georg Brandl3ee81df2008-05-17 18:14:43 +00003468- Compiler now generates simpler and faster code for dictionary
3469 literals. The oparg for BUILD_MAP now indicates an estimated
3470 dictionary size. There is a new opcode, STORE_MAP, for adding
3471 entries to the dictionary.

3496
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- Issue #1460: The utf-7 incremental decoder did not accept truncated
3498 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003499
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500- Patch #1739468: Directories and zipfiles containing a __main__.py
3501 file can now be directly executed by passing their name to the
3502 interpreter. The directory/zipfile is automatically inserted as the
3503 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003504
Georg Brandl3ee81df2008-05-17 18:14:43 +00003505- Issue #1265: Fix a problem with sys.settrace, if the tracing
3506 function uses a generator expression when at the same time the
3507 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003508
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003509- sets and frozensets now have an isdisjoint() method.
3510
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003511- optimize the performance of builtin.sum().
3512
Neal Norwitz44f326e2007-10-05 05:29:17 +00003513- Fix warnings found by the new version of the Coverity checker.
3514
Georg Brandl3ee81df2008-05-17 18:14:43 +00003515- The enumerate() builtin function is no longer bounded to sequences
3516 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3517 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003518
Georg Brandl3ee81df2008-05-17 18:14:43 +00003519- Issue #1686386: Tuple's tp_repr did not take into account the
3520 possibility of having a self-referential tuple, which is possible
3521 from C code. Nor did object's tp_str consider that a type's tp_str
3522 could do something that could lead to an inifinite recursion.
3523 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3524 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003525
Georg Brandl3ee81df2008-05-17 18:14:43 +00003526- Issue #1164: It was possible to trigger deadlock when using the
3527 'print' statement to write to a file since the GIL was not released
3528 as needed. Now PyObject_Print() does the right thing along with
3529 various tp_print implementations of the built-in types and those in
3530 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Issue #1147: Exceptions were directly allowing string exceptions in
3533 their throw() method even though string exceptions no longer
3534 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003535
Georg Brandl3ee81df2008-05-17 18:14:43 +00003536- Issue #1096: Prevent a segfault from getting the repr of a very
3537 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003538
Brett Cannon1e534b52007-09-07 04:18:30 +00003539- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540 PyObject_Call() never calling back out to Python code to trigger
3541 recursion depth updates/checks. Required the creation of a static
3542 RuntimeError instance in case normalizing an exception put the
3543 recursion check value past its limit. Fixes crashers
3544 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003545
Georg Brandl3ee81df2008-05-17 18:14:43 +00003546- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003559- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003560 __*__ attributes. (Some already existed, e.g., __doc__ and
3561 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003562
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003563- Add -3 option to the interpreter to warn about features that are
3564 deprecated and will be changed/removed in Python 3.0.
3565
Georg Brandl2134e752007-05-21 20:34:16 +00003566- Patch #1686487: you can now pass any mapping after '**' in function
3567 calls.
3568
Collin Winter62903052007-05-18 23:11:24 +00003569- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003570 "except E as target:". This is to provide forwards compatibility
3571 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003572
Brett Cannon229cee22007-05-05 01:34:02 +00003573- Deprecate BaseException.message as per PEP 352.
3574
Georg Brandl3ee81df2008-05-17 18:14:43 +00003575- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003576 inherited from a builtin base.
3577
Vinay Sajip8549ce32007-05-06 17:53:37 +00003578- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003579 setting a plain string, ie don't expand to single letter identifiers.
3580
Raymond Hettinger13936692007-04-11 18:40:58 +00003581- Request #1191699: Slices can now be pickled.
3582
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003583- Request #1193128: str.translate() now allows a None argument for
3584 translations that only remove characters without re-mapping the
3585 remaining characters.
3586
Georg Brandl5cb76c12007-03-21 09:00:39 +00003587- Patch #1682205: a TypeError while unpacking an iterable is no longer
3588 masked by a generic one with the message "unpack non-sequence".
3589
Neal Norwitzaa754b72007-03-21 06:39:48 +00003590- Remove unused file Python/fmod.c.
3591
Guido van Rossum143b5642007-03-23 04:58:42 +00003592- Bug #1683368: The object.__init__() and object.__new__() methods are
3593 now stricter in rejecting excess arguments. The only time when
3594 either allows excess arguments is when it is not overridden and the
3595 other one is. For backwards compatibility, when both are
3596 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003597 warning later). Also, type.__init__() insists on the same signature
3598 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003599
Georg Brandl3ee81df2008-05-17 18:14:43 +00003600- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3601 object to complex using its __complex__() method before falling back
3602 to the __float__() method. Therefore, the functions in the cmath

Georg Brandl3ee81df2008-05-17 18:14:43 +00003626 its argument, if it exists. If not, it will work like before. This
3627 allows customizing the output of dir() in the presence of a
3628 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003640- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003710- Bug #1545497: when given an explicit base, int() did ignore NULs
3711 embedded in the string to convert.
3712
Georg Brandl846f73a2006-10-08 07:11:54 +00003713- Bug #1569998: break inside a try statement (outside a loop) is now
3714 recognized and rejected.

Georg Brandl4e933132006-09-06 20:05:58 +00003743- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003761 generator expressions (x for x, in ... ) works again. Fixing this
3762 problem required changing the .pyc magic number. This means that
3763 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004575- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004576 that the SMTP.starttls() caller no longer needs to call ehlo()
4577 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004578 does not claim to support starttls. Adds the
4579 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4660 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4661 silently miscode subclasses of those types. Now, it raises a
4662 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004663

Georg Brandl3ee81df2008-05-17 18:14:43 +00004678 time so that opening a database previously created with the DB_DUP
4679 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4680 opens. Specifically: dictionary assignment to a DB object will
4681 replace all values for a given key when the database allows
4682 duplicate values. DB users should use DB.put(k, v) when they want
4683 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004684

4690 characters with ASCII value less than 32. Also, it correctly quotes
4691 dots only if they occur on a single line, as opposed to the previous
4692 behavior of quoting dots if they are the second character of any
4693 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004694
