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

446Core and Builtins
447-----------------
448
Mark Dickinson865e01a2009-05-07 16:37:01 +0000449- Issue #5914: Add new C API function PyOS_string_to_double, and
450 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
451
Eric Smith741191f2009-05-06 13:08:15 +0000452- Issue #3382: float.__format__, complex.__format__, and %-formatting
453 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
454 affects nan -> NAN and inf -> INF.
455
Mark Hammond5a607a32009-05-06 08:04:54 +0000456- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
457 in all operations, including splitdrive, split, etc. splitunc() now issues
458 a PendingDeprecation warning.
459
Eric Smith63376222009-05-05 14:04:18 +0000460- Issue #5920: For float.__format__, change the behavior with the
461 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
462 to be like 'g' but with at least one decimal point and with a
463 default precision of 12. Previously, the behavior the same but with
464 a default precision of 6. This more closely matches str(), and
465 reduces surprises when adding alignment flags to the empty
466 presentation type. This also affects the new complex.__format__ in
467 the same way.
468
Martin v. Löwis011e8422009-05-05 04:43:17 +0000469- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
470
R. David Murrayb18500d2009-05-04 22:59:07 +0000471- Issue #5890: in subclasses of 'property' the __doc__ attribute was
472 shadowed by classtype's, even if it was None. property now
473 inserts the __doc__ into the subclass instance __dict__.
474
Antoine Pitrou244651a2009-05-04 18:56:13 +0000475- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
476 sequences. Patch by Nick Barnes and Victor Stinner.
477
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000478- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000479
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000480- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
481 received a new method, detach(). detach() disconnects the underlying stream
482 from the buffer or text IO and returns it.
483
Mark Dickinson33841c32009-05-01 15:37:04 +0000484- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
485 floats with absolute value over 1e50. Also remove length
486 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
487 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000488
Eric Smith741191f2009-05-06 13:08:15 +0000489- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000490 format(complex(1, 2./3), '.5') now produces a sensible result.
491
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000492- Issue #5864: Fix empty format code formatting for floats so that it
493 never gives more than the requested number of significant digits.
494
Eric Smith6dc46f52009-04-27 20:39:49 +0000495- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
496 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
497
Eric Smithcc32a112009-04-26 21:35:14 +0000498- Issue #5835: Deprecate PyOS_ascii_formatd.
499
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000500- Issue #4971: Fix titlecase for characters that are their own
501 titlecase, but not their own uppercase.
502
Benjamin Peterson193152c2009-04-25 01:08:45 +0000503- Issue #5283: Setting __class__ in __del__ caused a segfault.
504
Mark Dickinsonad476da2009-04-23 19:14:16 +0000505- Issue #5816: complex(repr(z)) now recovers z exactly, even when
506 z involves nans, infs or negative zeros.
507
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000508- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000509
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000510- Issue #1869 (and many duplicates): make round(x, n) correctly
511 rounded for a float x, by using the decimal <-> binary conversions
512 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
513 consistently agrees with format(x, '.2f').
514
Benjamin Petersonae937c02009-04-18 20:54:08 +0000515- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
516 some builtin types.
517
Eric Smith0923d1d2009-04-16 20:16:10 +0000518- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
519
Eric Smith35e84722009-04-16 20:21:28 +0000520- Issue #5515: str.format() type 'n' combined with commas and leading
521 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000522
523- Implement PEP 378, Format Specifier for Thousands Separator, for
524 floats.
525
Mark Dickinson3370cce2009-04-17 22:40:53 +0000526- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000527 1e11, not 1e12. This avoids printing 13 significant digits in
528 situations where only 12 of them are correct. Example problem
529 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
530 long time.)
531
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000532- Issue #1580: On most platforms, use a 'short' float repr: for a
533 finite float x, repr(x) now outputs a string based on the shortest
534 sequence of decimal digits that rounds to x. Previous behaviour was
535 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000536 Another minor difference is that the new repr switches to
537 exponential notation at 1e16 instead of the previous 1e17; this
538 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000539
540 There's a new sys attribute sys.float_repr_style, which takes
541 the value 'short' to indicate that we're using short float repr,
542 and 'legacy' if the short float repr isn't available for one
543 reason or another.
544
545 The float repr change involves incorporating David Gay's 'perfect
546 rounding' code into the Python core (it's in Python/dtoa.c). As a
547 secondary consequence, all string-to-float and float-to-string
548 conversions (including all float formatting operations) will be
549 correctly rounded on these platforms.
550
551 See issue 1580 discussions for details of platforms for which
552 this change does not apply.
553
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000554- Issue #5759: float() didn't call __float__ on str subclasses.
555
Georg Brandlabc38772009-04-12 15:51:51 +0000556- The string.maketrans() function is deprecated; there is a new static method
557 maketrans() on the bytes and bytearray classes. This removes confusion about
558 the types string.maketrans() is supposed to work with, and mirrors the
559 methods available on the str class.
560
R. David Murraydc6da8a2009-04-09 22:16:43 +0000561- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
562 its clarity and its speed.
563
Matthias Klose091c7b12009-04-07 13:24:27 +0000564- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
565 to avoid compiler warnings.
566
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000567- Issue #3739: The unicode-internal encoder now reports the number of characters
568 consumed like any other encoder (instead of the number of bytes).

704
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000705- Issue #5499: The 'c' code for argument parsing functions now only accepts a
706 byte, and the 'C' code only accepts a unicode character.

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

799 forever on incomplete input. That caused tarfile.open() to hang when used
800 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
801 partial bzip2 compressed data.
802
Mark Dickinson79f52032009-03-17 23:12:51 +0000803- Issue #2110: Add support for thousands separator and 'n' type

918 flag to work properly. Furthermore, when specifying -u, the text stdout
919 and stderr streams have line-by-line buffering enabled (the default being
920 to buffer arbitrary chunks of data).
921
Raymond Hettinger35631532009-01-09 03:58:09 +0000922- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
923 instead of ints (reducing its size from 4 to 8 times thereby reducing
924 Python's overall memory).

976
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000977- Issue #4445: Replace "sizeof(PyBytesObject)" with

990 method on file objects with closefd=False. The file descriptor is still
991 kept open but the file object behaves like a closed file. The ``FileIO``
992 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000993

1002 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1003 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1004 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou08838b62009-01-21 00:55:13 +00001309- Issue #5008: When a file is opened in append mode with the new IO library,
1310 do an explicit seek to the end of file (so that e.g. tell() returns the
