342 (1) inf and nan strings with trailing whitespace were incorrectly
343 rejected; (2) parsing of strings representing infinities and nans
344 was locale aware; and (3) the interpretation of fromhex('-nan')
345 didn't match that of float('-nan').

448Core and Builtins
449-----------------
450
Mark Dickinson865e01a2009-05-07 16:37:01 +0000451- Issue #5914: Add new C API function PyOS_string_to_double, and
452 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
453
Eric Smith741191f2009-05-06 13:08:15 +0000454- Issue #3382: float.__format__, complex.__format__, and %-formatting
455 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
456 affects nan -> NAN and inf -> INF.
457
Mark Hammond5a607a32009-05-06 08:04:54 +0000458- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
459 in all operations, including splitdrive, split, etc. splitunc() now issues
460 a PendingDeprecation warning.
461
Eric Smith63376222009-05-05 14:04:18 +0000462- Issue #5920: For float.__format__, change the behavior with the
463 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
464 to be like 'g' but with at least one decimal point and with a
465 default precision of 12. Previously, the behavior the same but with
466 a default precision of 6. This more closely matches str(), and
467 reduces surprises when adding alignment flags to the empty
468 presentation type. This also affects the new complex.__format__ in
469 the same way.
470
Martin v. Löwis011e8422009-05-05 04:43:17 +0000471- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
472
R. David Murrayb18500d2009-05-04 22:59:07 +0000473- Issue #5890: in subclasses of 'property' the __doc__ attribute was
474 shadowed by classtype's, even if it was None. property now
475 inserts the __doc__ into the subclass instance __dict__.
476
Antoine Pitrou244651a2009-05-04 18:56:13 +0000477- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
478 sequences. Patch by Nick Barnes and Victor Stinner.
479
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000480- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000481
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000482- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
483 received a new method, detach(). detach() disconnects the underlying stream
484 from the buffer or text IO and returns it.
485
Mark Dickinson33841c32009-05-01 15:37:04 +0000486- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
487 floats with absolute value over 1e50. Also remove length
488 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
489 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000490
Eric Smith741191f2009-05-06 13:08:15 +0000491- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000492 format(complex(1, 2./3), '.5') now produces a sensible result.
493
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000494- Issue #5864: Fix empty format code formatting for floats so that it
495 never gives more than the requested number of significant digits.
496
Eric Smith6dc46f52009-04-27 20:39:49 +0000497- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
498 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
499
Eric Smithcc32a112009-04-26 21:35:14 +0000500- Issue #5835: Deprecate PyOS_ascii_formatd.
501
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000502- Issue #4971: Fix titlecase for characters that are their own
503 titlecase, but not their own uppercase.
504
Benjamin Peterson193152c2009-04-25 01:08:45 +0000505- Issue #5283: Setting __class__ in __del__ caused a segfault.
506
Mark Dickinsonad476da2009-04-23 19:14:16 +0000507- Issue #5816: complex(repr(z)) now recovers z exactly, even when
508 z involves nans, infs or negative zeros.
509
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000510- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000511
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000512- Issue #1869 (and many duplicates): make round(x, n) correctly
513 rounded for a float x, by using the decimal <-> binary conversions
514 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
515 consistently agrees with format(x, '.2f').
516
Benjamin Petersonae937c02009-04-18 20:54:08 +0000517- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
518 some builtin types.
519
Eric Smith0923d1d2009-04-16 20:16:10 +0000520- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
521
Eric Smith35e84722009-04-16 20:21:28 +0000522- Issue #5515: str.format() type 'n' combined with commas and leading
523 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000524
525- Implement PEP 378, Format Specifier for Thousands Separator, for
526 floats.
527
Mark Dickinson3370cce2009-04-17 22:40:53 +0000528- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000529 1e11, not 1e12. This avoids printing 13 significant digits in
530 situations where only 12 of them are correct. Example problem
531 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
532 long time.)
533
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000534- Issue #1580: On most platforms, use a 'short' float repr: for a
535 finite float x, repr(x) now outputs a string based on the shortest
536 sequence of decimal digits that rounds to x. Previous behaviour was
537 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000538 Another minor difference is that the new repr switches to
539 exponential notation at 1e16 instead of the previous 1e17; this
540 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000541
542 There's a new sys attribute sys.float_repr_style, which takes
543 the value 'short' to indicate that we're using short float repr,
544 and 'legacy' if the short float repr isn't available for one
545 reason or another.
546
547 The float repr change involves incorporating David Gay's 'perfect
548 rounding' code into the Python core (it's in Python/dtoa.c). As a
549 secondary consequence, all string-to-float and float-to-string
550 conversions (including all float formatting operations) will be
551 correctly rounded on these platforms.
552
553 See issue 1580 discussions for details of platforms for which
554 this change does not apply.
555
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000556- Issue #5759: float() didn't call __float__ on str subclasses.
557
Georg Brandlabc38772009-04-12 15:51:51 +0000558- The string.maketrans() function is deprecated; there is a new static method
559 maketrans() on the bytes and bytearray classes. This removes confusion about
560 the types string.maketrans() is supposed to work with, and mirrors the
561 methods available on the str class.
562
R. David Murraydc6da8a2009-04-09 22:16:43 +0000563- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
564 its clarity and its speed.
565
Matthias Klose091c7b12009-04-07 13:24:27 +0000566- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
567 to avoid compiler warnings.
568
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000569- Issue #3739: The unicode-internal encoder now reports the number of characters
570 consumed like any other encoder (instead of the number of bytes).

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

801 forever on incomplete input. That caused tarfile.open() to hang when used
802 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
803 partial bzip2 compressed data.
804
Mark Dickinson79f52032009-03-17 23:12:51 +0000805- Issue #2110: Add support for thousands separator and 'n' type

930 code objects if the original filename is obsolete (which can happen if the
931 file has been renamed, moved, or if it is accessed through different paths).

994 object also got a new readonly attribute ``closefd``.

1004 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1005 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1006 of using the replace error handler in PyUnicode_DecodeUTF8().

1310
Antoine Pitrou08838b62009-01-21 00:55:13 +00001311- Issue #5008: When a file is opened in append mode with the new IO library,
1312 do an explicit seek to the end of file (so that e.g. tell() returns the
1313 file size rather than 0). This is consistent with the behaviour of the

1344 appropriately when it is being used via socket.makefile() objects
1345 rather than delaying the close by waiting for garbage collection to do it.
