Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000325- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
326 (1) inf and nan strings with trailing whitespace were incorrectly
327 rejected; (2) parsing of strings representing infinities and nans
328 was locale aware; and (3) the interpretation of fromhex('-nan')
329 didn't match that of float('-nan').

432Core and Builtins
433-----------------
434
Mark Dickinson865e01a2009-05-07 16:37:01 +0000435- Issue #5914: Add new C API function PyOS_string_to_double, and
436 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
437
Eric Smith741191f2009-05-06 13:08:15 +0000438- Issue #3382: float.__format__, complex.__format__, and %-formatting
439 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
440 affects nan -> NAN and inf -> INF.
441
Mark Hammond5a607a32009-05-06 08:04:54 +0000442- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
443 in all operations, including splitdrive, split, etc. splitunc() now issues
444 a PendingDeprecation warning.
445
Eric Smith63376222009-05-05 14:04:18 +0000446- Issue #5920: For float.__format__, change the behavior with the
447 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
448 to be like 'g' but with at least one decimal point and with a
449 default precision of 12. Previously, the behavior the same but with
450 a default precision of 6. This more closely matches str(), and
451 reduces surprises when adding alignment flags to the empty
452 presentation type. This also affects the new complex.__format__ in
453 the same way.
454
Martin v. Löwis011e8422009-05-05 04:43:17 +0000455- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
456
R. David Murrayb18500d2009-05-04 22:59:07 +0000457- Issue #5890: in subclasses of 'property' the __doc__ attribute was
458 shadowed by classtype's, even if it was None. property now
459 inserts the __doc__ into the subclass instance __dict__.
460
Antoine Pitrou244651a2009-05-04 18:56:13 +0000461- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
462 sequences. Patch by Nick Barnes and Victor Stinner.
463
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000464- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000465
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000466- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
467 received a new method, detach(). detach() disconnects the underlying stream
468 from the buffer or text IO and returns it.
469
Mark Dickinson33841c32009-05-01 15:37:04 +0000470- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
471 floats with absolute value over 1e50. Also remove length
472 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
473 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000474
Eric Smith741191f2009-05-06 13:08:15 +0000475- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000476 format(complex(1, 2./3), '.5') now produces a sensible result.
477
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000478- Issue #5864: Fix empty format code formatting for floats so that it
479 never gives more than the requested number of significant digits.
480
Eric Smith6dc46f52009-04-27 20:39:49 +0000481- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
482 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
483
Eric Smithcc32a112009-04-26 21:35:14 +0000484- Issue #5835: Deprecate PyOS_ascii_formatd.
485
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000486- Issue #4971: Fix titlecase for characters that are their own
487 titlecase, but not their own uppercase.
488
Benjamin Peterson193152c2009-04-25 01:08:45 +0000489- Issue #5283: Setting __class__ in __del__ caused a segfault.
490
Mark Dickinsonad476da2009-04-23 19:14:16 +0000491- Issue #5816: complex(repr(z)) now recovers z exactly, even when
492 z involves nans, infs or negative zeros.
493
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000494- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000495
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000496- Issue #1869 (and many duplicates): make round(x, n) correctly
497 rounded for a float x, by using the decimal <-> binary conversions
498 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
499 consistently agrees with format(x, '.2f').
500
Benjamin Petersonae937c02009-04-18 20:54:08 +0000501- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
502 some builtin types.
503
Eric Smith0923d1d2009-04-16 20:16:10 +0000504- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
505
Eric Smith35e84722009-04-16 20:21:28 +0000506- Issue #5515: str.format() type 'n' combined with commas and leading
507 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000508
509- Implement PEP 378, Format Specifier for Thousands Separator, for
510 floats.
511
Mark Dickinson3370cce2009-04-17 22:40:53 +0000512- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000513 1e11, not 1e12. This avoids printing 13 significant digits in
514 situations where only 12 of them are correct. Example problem
515 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
516 long time.)
517
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000518- Issue #1580: On most platforms, use a 'short' float repr: for a
519 finite float x, repr(x) now outputs a string based on the shortest
520 sequence of decimal digits that rounds to x. Previous behaviour was
521 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000522 Another minor difference is that the new repr switches to
523 exponential notation at 1e16 instead of the previous 1e17; this
524 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000525
526 There's a new sys attribute sys.float_repr_style, which takes
527 the value 'short' to indicate that we're using short float repr,
528 and 'legacy' if the short float repr isn't available for one
529 reason or another.
530
531 The float repr change involves incorporating David Gay's 'perfect
532 rounding' code into the Python core (it's in Python/dtoa.c). As a
533 secondary consequence, all string-to-float and float-to-string
534 conversions (including all float formatting operations) will be
535 correctly rounded on these platforms.
536
537 See issue 1580 discussions for details of platforms for which
538 this change does not apply.
539
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000540- Issue #5759: float() didn't call __float__ on str subclasses.
541
Georg Brandlabc38772009-04-12 15:51:51 +0000542- The string.maketrans() function is deprecated; there is a new static method
543 maketrans() on the bytes and bytearray classes. This removes confusion about
544 the types string.maketrans() is supposed to work with, and mirrors the
545 methods available on the str class.
546
R. David Murraydc6da8a2009-04-09 22:16:43 +0000547- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
548 its clarity and its speed.
549
Matthias Klose091c7b12009-04-07 13:24:27 +0000550- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
551 to avoid compiler warnings.
552
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000553- Issue #3739: The unicode-internal encoder now reports the number of characters
554 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +0000632- Issue #1161031: fix readwrite select flag handling: POLLPRI now
633 results in a handle_expt_event call, not handle_read_event, and POLLERR
634 and POLLNVAL now call handle_close, not handle_expt_event. Also,
635 dispatcher now has an 'ignore_log_types' attribute for suppressing

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000689- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
690
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000691- Issue #5499: The 'c' code for argument parsing functions now only accepts a
692 byte, and the 'C' code only accepts a unicode character.
693
Georg Brandl406b3d82009-04-11 21:24:37 +0000694- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

710
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000711- Issue #4688: Add a heuristic so that tuples and dicts containing only
712 untrackable objects are not tracked by the garbage collector. This can
713 reduce the size of collections and therefore the garbage collection overhead
714 on long-running programs, depending on their particular use of datatypes.

Lars Gustäbel42e00912009-03-22 20:34:29 +0000784- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
785 forever on incomplete input. That caused tarfile.open() to hang when used
786 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
787 partial bzip2 compressed data.
788
Mark Dickinson79f52032009-03-17 23:12:51 +0000789- Issue #2110: Add support for thousands separator and 'n' type

904 flag to work properly. Furthermore, when specifying -u, the text stdout
905 and stderr streams have line-by-line buffering enabled (the default being
906 to buffer arbitrary chunks of data).
907
Raymond Hettinger35631532009-01-09 03:58:09 +0000908- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
909 instead of ints (reducing its size from 4 to 8 times thereby reducing
910 Python's overall memory).
911
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000912- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
913 an existing .py counterpart, override the co_filename attributes of all

920 items, rather than the size in bytes.
921

Antoine Pitrou08838b62009-01-21 00:55:13 +00001293- Issue #5008: When a file is opened in append mode with the new IO library,
1294 do an explicit seek to the end of file (so that e.g. tell() returns the
