65
Brett Cannon64ef00f2009-07-20 03:19:18 +000066- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

Antoine Pitroue4501852009-05-14 18:55:55 +0000327- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
328 library. This means, for example, that opening an UTF-16 text file in
329 append mode doesn't add a BOM at the end of the file if the file isn't
330 empty.
331
R. David Murray74b89242009-05-13 17:33:03 +0000332- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
333 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
334 corrects a pydoc regression.
335
R. David Murray99352742009-05-07 18:24:38 +0000336- Issue 5955: aifc's close method did not close the file it wrapped,
337 now it does. This also means getfp method now returns the real fp.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000378*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000379
380Core and Builtins
381-----------------
382
Mark Dickinson865e01a2009-05-07 16:37:01 +0000383- Issue #5914: Add new C API function PyOS_string_to_double, and
384 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
385
Eric Smith741191f2009-05-06 13:08:15 +0000386- Issue #3382: float.__format__, complex.__format__, and %-formatting
387 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
388 affects nan -> NAN and inf -> INF.
389
Mark Hammond5a607a32009-05-06 08:04:54 +0000390- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
391 in all operations, including splitdrive, split, etc. splitunc() now issues
392 a PendingDeprecation warning.
393
Eric Smith63376222009-05-05 14:04:18 +0000394- Issue #5920: For float.__format__, change the behavior with the
395 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
396 to be like 'g' but with at least one decimal point and with a
397 default precision of 12. Previously, the behavior the same but with
398 a default precision of 6. This more closely matches str(), and
399 reduces surprises when adding alignment flags to the empty
400 presentation type. This also affects the new complex.__format__ in
401 the same way.
402
Martin v. Löwis011e8422009-05-05 04:43:17 +0000403- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
404
R. David Murrayb18500d2009-05-04 22:59:07 +0000405- Issue #5890: in subclasses of 'property' the __doc__ attribute was
406 shadowed by classtype's, even if it was None. property now
407 inserts the __doc__ into the subclass instance __dict__.
408
Antoine Pitrou244651a2009-05-04 18:56:13 +0000409- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
410 sequences. Patch by Nick Barnes and Victor Stinner.
411
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000412- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000413
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000414- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
415 received a new method, detach(). detach() disconnects the underlying stream
416 from the buffer or text IO and returns it.
417
Mark Dickinson33841c32009-05-01 15:37:04 +0000418- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
419 floats with absolute value over 1e50. Also remove length
420 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
421 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000422
Eric Smith741191f2009-05-06 13:08:15 +0000423- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000424 format(complex(1, 2./3), '.5') now produces a sensible result.
425
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000426- Issue #5864: Fix empty format code formatting for floats so that it
427 never gives more than the requested number of significant digits.
428
Eric Smith6dc46f52009-04-27 20:39:49 +0000429- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
430 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
431
Eric Smithcc32a112009-04-26 21:35:14 +0000432- Issue #5835: Deprecate PyOS_ascii_formatd.
433
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000434- Issue #4971: Fix titlecase for characters that are their own
435 titlecase, but not their own uppercase.
436
Benjamin Peterson193152c2009-04-25 01:08:45 +0000437- Issue #5283: Setting __class__ in __del__ caused a segfault.
438
Mark Dickinsonad476da2009-04-23 19:14:16 +0000439- Issue #5816: complex(repr(z)) now recovers z exactly, even when
440 z involves nans, infs or negative zeros.
441
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000442- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000443
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000444- Issue #1869 (and many duplicates): make round(x, n) correctly
445 rounded for a float x, by using the decimal <-> binary conversions
446 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
447 consistently agrees with format(x, '.2f').
448
Benjamin Petersonae937c02009-04-18 20:54:08 +0000449- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
450 some builtin types.
451
Eric Smith0923d1d2009-04-16 20:16:10 +0000452- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
453
Eric Smith35e84722009-04-16 20:21:28 +0000454- Issue #5515: str.format() type 'n' combined with commas and leading
455 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000456
457- Implement PEP 378, Format Specifier for Thousands Separator, for
458 floats.
459
Mark Dickinson3370cce2009-04-17 22:40:53 +0000460- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000461 1e11, not 1e12. This avoids printing 13 significant digits in
462 situations where only 12 of them are correct. Example problem
463 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
464 long time.)
465
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000466- Issue #1580: On most platforms, use a 'short' float repr: for a
467 finite float x, repr(x) now outputs a string based on the shortest
468 sequence of decimal digits that rounds to x. Previous behaviour was
469 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000470 Another minor difference is that the new repr switches to
471 exponential notation at 1e16 instead of the previous 1e17; this
472 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000473
474 There's a new sys attribute sys.float_repr_style, which takes
475 the value 'short' to indicate that we're using short float repr,
476 and 'legacy' if the short float repr isn't available for one
477 reason or another.
478
479 The float repr change involves incorporating David Gay's 'perfect
480 rounding' code into the Python core (it's in Python/dtoa.c). As a
481 secondary consequence, all string-to-float and float-to-string
482 conversions (including all float formatting operations) will be
483 correctly rounded on these platforms.
484
485 See issue 1580 discussions for details of platforms for which
486 this change does not apply.
487
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000488- Issue #5759: float() didn't call __float__ on str subclasses.
489
Georg Brandlabc38772009-04-12 15:51:51 +0000490- The string.maketrans() function is deprecated; there is a new static method
491 maketrans() on the bytes and bytearray classes. This removes confusion about
492 the types string.maketrans() is supposed to work with, and mirrors the
493 methods available on the str class.
494
R. David Murraydc6da8a2009-04-09 22:16:43 +0000495- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
496 its clarity and its speed.
497
Matthias Klose091c7b12009-04-07 13:24:27 +0000498- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
499 to avoid compiler warnings.
500
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000501- Issue #3739: The unicode-internal encoder now reports the number of characters
502 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000637- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
638
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000639- Issue #5499: The 'c' code for argument parsing functions now only accepts a
640 byte, and the 'C' code only accepts a unicode character.
641
Georg Brandl406b3d82009-04-11 21:24:37 +0000642- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
643 when hitting the recursion limit under certain circumstances.
644
Brett Cannon0759dd62009-04-01 18:13:07 +0000645- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
646
Georg Brandlab6f2f62009-03-31 04:16:10 +0000647- Fix a segfault when running test_exceptions with coverage, caused by
648 insufficient checks in accessors of Exception.__context__.
649
Guido van Rossum0ad59d42009-03-30 22:01:35 +0000650- Issue #5604: non-ASCII characters in module name passed to
651 imp.find_module() were converted to UTF-8 while the path is
652 converted to the default filesystem encoding, causing nonsense.
653
Benjamin Peterson09832742009-03-26 17:15:46 +0000654- Issue #5126: str.isprintable() returned False for space characters.
655
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +0000656- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
657 the end sys.path, for compatibility with the system install of Python.
658
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000659- Issue #4688: Add a heuristic so that tuples and dicts containing only
660 untrackable objects are not tracked by the garbage collector. This can
661 reduce the size of collections and therefore the garbage collection overhead
662 on long-running programs, depending on their particular use of datatypes.
663
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000664- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

666 are now between 50% and 150% faster.
667
Mark Dickinsonbd792642009-03-18 20:06:12 +0000668- Issue #4258: Make it possible to use base 2**30 instead of base
669 2**15 for the internal representation of integers, for performance
670 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
671 --enable-big-digits option to configure, which overrides the
672 default. Add sys.int_info structseq to provide information about
673 the internal format.
674
Mark Dickinson081dfee2009-03-18 14:47:41 +0000675- Issue #4474: PyUnicode_FromWideChar now converts characters outside
676 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
677 and sizeof(Py_UNICODE) == 2.
678
Eric Smith8ec90442009-03-14 12:29:34 +0000679- Issue #5237: Allow auto-numbered fields in str.format(). For
680 example: '{} {}'.format(1, 2) == '1 2'.
681
Antoine Pitrou652e7072009-03-13 19:25:20 +0000682- Issue #5392: when a very low recursion limit was set, the interpreter would
683 abort with a fatal error after the recursion limit was hit twice.
684
Matthias Klose042f1332009-04-04 14:32:42 +0000685- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000798- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000799 were suppressing all exceptions. These include list() and bytearray().
800
Mark Dickinson1124e712009-01-28 21:25:58 +0000801- Issue #4707: round(x, n) now returns an integer if x is an integer.
802 Previously it returned a float.
803
Antoine Pitroub52ec782009-01-25 16:34:23 +0000804- Issue #4753: By enabling a configure option named '--with-computed-gotos'
805 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
806 evaluation loop is compiled with a new dispatch mechanism which gives
807 speedups of up to 20%, depending on the system, on various benchmarks.
808
Antoine Pitrou81fabdb2009-01-22 10:11:36 +0000809- Issue #4874: Most builtin decoders now reject unicode input.

817 optional module state data.
818
Mark Dickinson8055afd2009-01-17 10:04:45 +0000819- Issue #4910: Rename nb_long slot to nb_reserved, and change its
820 type to (void *).
821
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000822- Issue #4935: The overflow checking code in the expandtabs() method common
823 to str, bytes and bytearray could be optimized away by the compiler, letting
824 the interpreter segfault instead of raising an error.
825
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000826- Issue #3720: Fix a crash when an iterator modifies its class and removes its
827 __next__ method.
828
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000829- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
830 function no longer attempt to call the __long__ slot to convert an object
831 to an integer. Only the __int__ and __trunc__ slots are examined.

836
Antoine Pitrouab868312009-01-10 15:40:25 +0000837- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
838 common cases are optimized thanks to a dedicated fast path and a moderate
839 amount of loop unrolling.
840
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000841- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
842 collecting the oldest generation) so that allocating lots of objects without
843 destroying them does not show quadratic performance. Based on a proposal by
844 Martin von Löwis at
845 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
846
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000847- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000848 having been closed (for instance, a read() call could return some
849 previously buffered data). Patch by Dmitry Vasiliev.
850
Antoine Pitrou05608432009-01-09 18:53:14 +0000851- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
852 flag to work properly. Furthermore, when specifying -u, the text stdout
853 and stderr streams have line-by-line buffering enabled (the default being
854 to buffer arbitrary chunks of data).
855
Raymond Hettinger35631532009-01-09 03:58:09 +0000856- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
857 instead of ints (reducing its size from 4 to 8 times thereby reducing
858 Python's overall memory).
859
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000860- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
861 an existing .py counterpart, override the co_filename attributes of all
862 code objects if the original filename is obsolete (which can happen if the
863 file has been renamed, moved, or if it is accessed through different paths).
864 Patch by Ziga Seilnacht and Jean-Paul Calderone.
865
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000866- Issue #4580: Fix slicing of memoryviews when the item size is greater than
867 one byte. Also fixes the meaning of len() so that it returns the number of
868 items, rather than the size in bytes.
869
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000870- Issue #4075: Use OutputDebugStringW in Py_FatalError.
871
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000872- Issue #4747: When the terminal does not use utf-8, executing a script with
873 non-ascii characters in its name could fail with a "SyntaxError: None" error.
874
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000875- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000877
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000878- Issue #3680: Reference cycles created through a dict, set or deque iterator
879 did not get collected.
880
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000881- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
882 where the tp_hash and tp_dict slots are both NULL.
883
Georg Brandlccc47b62008-12-28 11:44:14 +0000884- Issue #4759: None is now allowed as the first argument of
885 bytearray.translate(). It was always allowed for bytes.translate().
886
Skip Montanaro80072cb2008-12-23 03:51:14 +0000887- Added test case to ensure attempts to read from a file opened for writing
888 fail.
889
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000890- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +0000892- Issue #2183: Simplify and optimize bytecode for list, dict and set
893 comprehensions. Original patch for list comprehensions by Neal Norwitz.
894
Antoine Pitrou621601a2008-12-17 23:18:19 +0000895- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
896 print elapsed times, not only when some objects are uncollectable /
897 unreachable. Original patch by Neil Schemenauer.
898
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000899- Issue #3439: Add a bit_length method to int.
900
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000901- Issue #2173: When getting device encoding, check that return value of
902 nl_langinfo is not the empty string. This was causing silent build
903 failures on OS X.
904
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000905- Issue #4597: Fixed several opcodes that weren't always propagating
906 exceptions.
907
908- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000909 context manager returns a value that cannot be converted to a bool.
910
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000911- Issue #4445: Replace "sizeof(PyBytesObject)" with
912 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
913 bytes instances. On a typical machine this saves 3 bytes of memory
914 (on average) per allocation of a bytes instance.
915
Christian Heimesa872de52008-12-05 08:26:55 +0000916- Issue #4533: File read operation was dreadfully slow due to a slowly
917 growing read buffer. Fixed by using the same growth rate algorithm as
918 Python 2.x.
919
Antoine Pitrou5504e892008-12-06 21:27:53 +0000920- Issue #4509: Various issues surrounding resize of bytearray objects to
921 which there are buffer exports (e.g. memoryview instances).
922
Georg Brandlf9734072008-12-07 15:30:06 +0000923- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
924 method on file objects with closefd=False. The file descriptor is still
925 kept open but the file object behaves like a closed file. The ``FileIO``
926 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000927
Antoine Pitroubc420402008-12-07 20:14:49 +0000928- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Antoine Pitrou88909542009-06-29 13:54:42 +00001517- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
1518 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00001520- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
1521 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1522 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1523 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00001525- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00001526 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00001527 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00001529- Issue #5083: New 'gui' resource for regrtest.
