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

441Core and Builtins
442-----------------
443
Mark Dickinson865e01a2009-05-07 16:37:01 +0000444- Issue #5914: Add new C API function PyOS_string_to_double, and
445 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
446
Eric Smith741191f2009-05-06 13:08:15 +0000447- Issue #3382: float.__format__, complex.__format__, and %-formatting
448 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
449 affects nan -> NAN and inf -> INF.
450
Mark Hammond5a607a32009-05-06 08:04:54 +0000451- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
452 in all operations, including splitdrive, split, etc. splitunc() now issues
453 a PendingDeprecation warning.
454
Eric Smith63376222009-05-05 14:04:18 +0000455- Issue #5920: For float.__format__, change the behavior with the
456 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
457 to be like 'g' but with at least one decimal point and with a
458 default precision of 12. Previously, the behavior the same but with
459 a default precision of 6. This more closely matches str(), and
460 reduces surprises when adding alignment flags to the empty
461 presentation type. This also affects the new complex.__format__ in
462 the same way.
463
Martin v. Löwis011e8422009-05-05 04:43:17 +0000464- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
465
R. David Murrayb18500d2009-05-04 22:59:07 +0000466- Issue #5890: in subclasses of 'property' the __doc__ attribute was
467 shadowed by classtype's, even if it was None. property now
468 inserts the __doc__ into the subclass instance __dict__.
469
Antoine Pitrou244651a2009-05-04 18:56:13 +0000470- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
471 sequences. Patch by Nick Barnes and Victor Stinner.
472
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000473- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000474
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000475- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
476 received a new method, detach(). detach() disconnects the underlying stream
477 from the buffer or text IO and returns it.
478
Mark Dickinson33841c32009-05-01 15:37:04 +0000479- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
480 floats with absolute value over 1e50. Also remove length
481 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
482 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000483
Eric Smith741191f2009-05-06 13:08:15 +0000484- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000485 format(complex(1, 2./3), '.5') now produces a sensible result.
486
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000487- Issue #5864: Fix empty format code formatting for floats so that it
488 never gives more than the requested number of significant digits.
489
Eric Smith6dc46f52009-04-27 20:39:49 +0000490- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
491 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
492
Eric Smithcc32a112009-04-26 21:35:14 +0000493- Issue #5835: Deprecate PyOS_ascii_formatd.
494
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000495- Issue #4971: Fix titlecase for characters that are their own
496 titlecase, but not their own uppercase.
497
Benjamin Peterson193152c2009-04-25 01:08:45 +0000498- Issue #5283: Setting __class__ in __del__ caused a segfault.
499
Mark Dickinsonad476da2009-04-23 19:14:16 +0000500- Issue #5816: complex(repr(z)) now recovers z exactly, even when
501 z involves nans, infs or negative zeros.
502
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000503- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000504
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000505- Issue #1869 (and many duplicates): make round(x, n) correctly
506 rounded for a float x, by using the decimal <-> binary conversions
507 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
508 consistently agrees with format(x, '.2f').
509
Benjamin Petersonae937c02009-04-18 20:54:08 +0000510- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
511 some builtin types.
512
Eric Smith0923d1d2009-04-16 20:16:10 +0000513- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
514
Eric Smith35e84722009-04-16 20:21:28 +0000515- Issue #5515: str.format() type 'n' combined with commas and leading
516 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000517
518- Implement PEP 378, Format Specifier for Thousands Separator, for
519 floats.
520
Mark Dickinson3370cce2009-04-17 22:40:53 +0000521- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000522 1e11, not 1e12. This avoids printing 13 significant digits in
523 situations where only 12 of them are correct. Example problem
524 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
525 long time.)
526
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000527- Issue #1580: On most platforms, use a 'short' float repr: for a
528 finite float x, repr(x) now outputs a string based on the shortest
529 sequence of decimal digits that rounds to x. Previous behaviour was
530 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000531 Another minor difference is that the new repr switches to
532 exponential notation at 1e16 instead of the previous 1e17; this
533 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000534
535 There's a new sys attribute sys.float_repr_style, which takes
536 the value 'short' to indicate that we're using short float repr,
537 and 'legacy' if the short float repr isn't available for one
538 reason or another.
539
540 The float repr change involves incorporating David Gay's 'perfect
541 rounding' code into the Python core (it's in Python/dtoa.c). As a
542 secondary consequence, all string-to-float and float-to-string
543 conversions (including all float formatting operations) will be
544 correctly rounded on these platforms.
545
546 See issue 1580 discussions for details of platforms for which
547 this change does not apply.
548
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000549- Issue #5759: float() didn't call __float__ on str subclasses.
550
Georg Brandlabc38772009-04-12 15:51:51 +0000551- The string.maketrans() function is deprecated; there is a new static method
552 maketrans() on the bytes and bytearray classes. This removes confusion about
553 the types string.maketrans() is supposed to work with, and mirrors the
554 methods available on the str class.
555
R. David Murraydc6da8a2009-04-09 22:16:43 +0000556- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
557 its clarity and its speed.
558
Matthias Klose091c7b12009-04-07 13:24:27 +0000559- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
560 to avoid compiler warnings.
561
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000562- Issue #3739: The unicode-internal encoder now reports the number of characters
563 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +0000641- Issue #1161031: fix readwrite select flag handling: POLLPRI now
642 results in a handle_expt_event call, not handle_read_event, and POLLERR
643 and POLLNVAL now call handle_close, not handle_expt_event. Also,
644 dispatcher now has an 'ignore_log_types' attribute for suppressing

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000698- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
699
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000700- Issue #5499: The 'c' code for argument parsing functions now only accepts a
701 byte, and the 'C' code only accepts a unicode character.
702
Georg Brandl406b3d82009-04-11 21:24:37 +0000703- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

719
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000720- Issue #4688: Add a heuristic so that tuples and dicts containing only
721 untrackable objects are not tracked by the garbage collector. This can
722 reduce the size of collections and therefore the garbage collection overhead
723 on long-running programs, depending on their particular use of datatypes.

794 forever on incomplete input. That caused tarfile.open() to hang when used
795 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
796 partial bzip2 compressed data.

913 flag to work properly. Furthermore, when specifying -u, the text stdout
914 and stderr streams have line-by-line buffering enabled (the default being
915 to buffer arbitrary chunks of data).
916
Raymond Hettinger35631532009-01-09 03:58:09 +0000917- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
918 instead of ints (reducing its size from 4 to 8 times thereby reducing
919 Python's overall memory).

1303
Antoine Pitrou08838b62009-01-21 00:55:13 +00001304- Issue #5008: When a file is opened in append mode with the new IO library,
1305 do an explicit seek to the end of file (so that e.g. tell() returns the
