332- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
333 tests on darwin even when the OS was installed on a case-sensitive
334 filesystem. Also fixed tests that should not be run when
335 sys.dont_write_bytecode is true.

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000341*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000342
343Core and Builtins
344-----------------
345
Mark Dickinson865e01a2009-05-07 16:37:01 +0000346- Issue #5914: Add new C API function PyOS_string_to_double, and
347 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
348
Eric Smith741191f2009-05-06 13:08:15 +0000349- Issue #3382: float.__format__, complex.__format__, and %-formatting
350 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
351 affects nan -> NAN and inf -> INF.
352
Mark Hammond5a607a32009-05-06 08:04:54 +0000353- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
354 in all operations, including splitdrive, split, etc. splitunc() now issues
355 a PendingDeprecation warning.
356
Eric Smith63376222009-05-05 14:04:18 +0000357- Issue #5920: For float.__format__, change the behavior with the
358 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
359 to be like 'g' but with at least one decimal point and with a
360 default precision of 12. Previously, the behavior the same but with
361 a default precision of 6. This more closely matches str(), and
362 reduces surprises when adding alignment flags to the empty
363 presentation type. This also affects the new complex.__format__ in
364 the same way.
365
Martin v. Löwis011e8422009-05-05 04:43:17 +0000366- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
367
R. David Murrayb18500d2009-05-04 22:59:07 +0000368- Issue #5890: in subclasses of 'property' the __doc__ attribute was
369 shadowed by classtype's, even if it was None. property now
370 inserts the __doc__ into the subclass instance __dict__.
371
Antoine Pitrou244651a2009-05-04 18:56:13 +0000372- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
373 sequences. Patch by Nick Barnes and Victor Stinner.
374
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000375- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000376
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000377- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
378 received a new method, detach(). detach() disconnects the underlying stream
379 from the buffer or text IO and returns it.
380
Mark Dickinson33841c32009-05-01 15:37:04 +0000381- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
382 floats with absolute value over 1e50. Also remove length
383 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
384 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000385
Eric Smith741191f2009-05-06 13:08:15 +0000386- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000387 format(complex(1, 2./3), '.5') now produces a sensible result.
388
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000389- Issue #5864: Fix empty format code formatting for floats so that it
390 never gives more than the requested number of significant digits.
391
Eric Smith6dc46f52009-04-27 20:39:49 +0000392- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
393 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
394
Eric Smithcc32a112009-04-26 21:35:14 +0000395- Issue #5835: Deprecate PyOS_ascii_formatd.
396
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000397- Issue #4971: Fix titlecase for characters that are their own
398 titlecase, but not their own uppercase.
399
Benjamin Peterson193152c2009-04-25 01:08:45 +0000400- Issue #5283: Setting __class__ in __del__ caused a segfault.
401
Mark Dickinsonad476da2009-04-23 19:14:16 +0000402- Issue #5816: complex(repr(z)) now recovers z exactly, even when
403 z involves nans, infs or negative zeros.
404
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000405- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000406
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000407- Issue #1869 (and many duplicates): make round(x, n) correctly
408 rounded for a float x, by using the decimal <-> binary conversions
409 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
410 consistently agrees with format(x, '.2f').
411
Benjamin Petersonae937c02009-04-18 20:54:08 +0000412- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
413 some builtin types.
414
Eric Smith0923d1d2009-04-16 20:16:10 +0000415- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
416
Eric Smith35e84722009-04-16 20:21:28 +0000417- Issue #5515: str.format() type 'n' combined with commas and leading
418 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000419
420- Implement PEP 378, Format Specifier for Thousands Separator, for
421 floats.
422
Mark Dickinson3370cce2009-04-17 22:40:53 +0000423- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000424 1e11, not 1e12. This avoids printing 13 significant digits in
425 situations where only 12 of them are correct. Example problem
426 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
427 long time.)
428
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000429- Issue #1580: On most platforms, use a 'short' float repr: for a
430 finite float x, repr(x) now outputs a string based on the shortest
431 sequence of decimal digits that rounds to x. Previous behaviour was
432 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000433 Another minor difference is that the new repr switches to
434 exponential notation at 1e16 instead of the previous 1e17; this
435 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000436
437 There's a new sys attribute sys.float_repr_style, which takes
438 the value 'short' to indicate that we're using short float repr,
439 and 'legacy' if the short float repr isn't available for one
440 reason or another.
441
442 The float repr change involves incorporating David Gay's 'perfect
443 rounding' code into the Python core (it's in Python/dtoa.c). As a
444 secondary consequence, all string-to-float and float-to-string
445 conversions (including all float formatting operations) will be
446 correctly rounded on these platforms.
447
448 See issue 1580 discussions for details of platforms for which
449 this change does not apply.
450
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000451- Issue #5759: float() didn't call __float__ on str subclasses.
452
Georg Brandlabc38772009-04-12 15:51:51 +0000453- The string.maketrans() function is deprecated; there is a new static method
454 maketrans() on the bytes and bytearray classes. This removes confusion about
455 the types string.maketrans() is supposed to work with, and mirrors the
456 methods available on the str class.
457
R. David Murraydc6da8a2009-04-09 22:16:43 +0000458- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
459 its clarity and its speed.
460
Matthias Klose091c7b12009-04-07 13:24:27 +0000461- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
462 to avoid compiler warnings.
463
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000464- Issue #3739: The unicode-internal encoder now reports the number of characters
465 consumed like any other encoder (instead of the number of bytes).

623 untrackable objects are not tracked by the garbage collector. This can
624 reduce the size of collections and therefore the garbage collection overhead
625 on long-running programs, depending on their particular use of datatypes.

743 source has already been decoded into str.
744
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000745- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
746 rotating the object pointer by 4 bits to the right.
747
Mark Dickinson87ec0852009-02-09 17:15:59 +0000748- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
749 it now forces its argument to double before testing for infinity.
750
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000751- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000761- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000762 were suppressing all exceptions. These include list() and bytearray().
763
Mark Dickinson1124e712009-01-28 21:25:58 +0000764- Issue #4707: round(x, n) now returns an integer if x is an integer.
765 Previously it returned a float.
766
Antoine Pitroub52ec782009-01-25 16:34:23 +0000767- Issue #4753: By enabling a configure option named '--with-computed-gotos'
768 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
769 evaluation loop is compiled with a new dispatch mechanism which gives
770 speedups of up to 20%, depending on the system, on various benchmarks.
771

Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000779- Issue #4838: When a module is deallocated, free the memory backing the
780 optional module state data.
781
Mark Dickinson8055afd2009-01-17 10:04:45 +0000782- Issue #4910: Rename nb_long slot to nb_reserved, and change its
783 type to (void *).
784
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000785- Issue #4935: The overflow checking code in the expandtabs() method common
786 to str, bytes and bytearray could be optimized away by the compiler, letting
787 the interpreter segfault instead of raising an error.
788
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000789- Issue #3720: Fix a crash when an iterator modifies its class and removes its
790 __next__ method.
791
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000792- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
793 function no longer attempt to call the __long__ slot to convert an object
794 to an integer. Only the __int__ and __trunc__ slots are examined.
795

799
Antoine Pitrouab868312009-01-10 15:40:25 +0000800- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
801 common cases are optimized thanks to a dedicated fast path and a moderate
802 amount of loop unrolling.
803
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000804- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
805 collecting the oldest generation) so that allocating lots of objects without
806 destroying them does not show quadratic performance. Based on a proposal by
807 Martin von Löwis at
808 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
809
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000810- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000811 having been closed (for instance, a read() call could return some
812 previously buffered data). Patch by Dmitry Vasiliev.
813
Antoine Pitrou05608432009-01-09 18:53:14 +0000814- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
815 flag to work properly. Furthermore, when specifying -u, the text stdout
816 and stderr streams have line-by-line buffering enabled (the default being
817 to buffer arbitrary chunks of data).
818
Raymond Hettinger35631532009-01-09 03:58:09 +0000819- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
820 instead of ints (reducing its size from 4 to 8 times thereby reducing
821 Python's overall memory).
822
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000823- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
824 an existing .py counterpart, override the co_filename attributes of all
825 code objects if the original filename is obsolete (which can happen if the
826 file has been renamed, moved, or if it is accessed through different paths).
827 Patch by Ziga Seilnacht and Jean-Paul Calderone.
828
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000829- Issue #4580: Fix slicing of memoryviews when the item size is greater than
830 one byte. Also fixes the meaning of len() so that it returns the number of
831 items, rather than the size in bytes.
832
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000833- Issue #4075: Use OutputDebugStringW in Py_FatalError.
834
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000835- Issue #4747: When the terminal does not use utf-8, executing a script with
836 non-ascii characters in its name could fail with a "SyntaxError: None" error.
837
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000838- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

Antoine Pitrou7ddda782009-01-01 15:35:33 +0000841- Issue #3680: Reference cycles created through a dict, set or deque iterator
842 did not get collected.
843
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000844- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
845 where the tp_hash and tp_dict slots are both NULL.
846
Georg Brandlccc47b62008-12-28 11:44:14 +0000847- Issue #4759: None is now allowed as the first argument of
848 bytearray.translate(). It was always allowed for bytes.translate().
849
Skip Montanaro80072cb2008-12-23 03:51:14 +0000850- Added test case to ensure attempts to read from a file opened for writing
851 fail.
852

860 unreachable. Original patch by Neil Schemenauer.
861
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000862- Issue #3439: Add a bit_length method to int.
863
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000864- Issue #2173: When getting device encoding, check that return value of

866 failures on OS X.
867
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000868- Issue #4597: Fixed several opcodes that weren't always propagating

870
871- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000872 context manager returns a value that cannot be converted to a bool.
873
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000874- Issue #4445: Replace "sizeof(PyBytesObject)" with
875 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
876 bytes instances. On a typical machine this saves 3 bytes of memory
877 (on average) per allocation of a bytes instance.
878
Christian Heimesa872de52008-12-05 08:26:55 +0000879- Issue #4533: File read operation was dreadfully slow due to a slowly
880 growing read buffer. Fixed by using the same growth rate algorithm as
881 Python 2.x.
882
Antoine Pitrou5504e892008-12-06 21:27:53 +0000883- Issue #4509: Various issues surrounding resize of bytearray objects to
884 which there are buffer exports (e.g. memoryview instances).
885
Georg Brandlf9734072008-12-07 15:30:06 +0000886- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
887 method on file objects with closefd=False. The file descriptor is still
888 kept open but the file object behaves like a closed file. The ``FileIO``
889 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +0000891- Issue #4569: Interpreter crash when mutating a memoryview with an item size

899 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
900 step. This avoids problems with counting UTF-8 bytes that ignores the effect
901 of using the replace error handler in PyUnicode_DecodeUTF8().
