302 that would raise SystemError.
303
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000304- Issue #5982: staticmethod and classmethod now expose the wrapped

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000310- Issue #5829: complex("1e500") no longer raises OverflowError. This
311 makes it consistent with float("1e500") and interpretation of real
312 and imaginary literals.
313
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000314- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

317
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000318- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
319 (1) inf and nan strings with trailing whitespace were incorrectly
320 rejected; (2) parsing of strings representing infinities and nans
321 was locale aware; and (3) the interpretation of fromhex('-nan')
322 didn't match that of float('-nan').

338 names: cls, self, tuple, itemgetter, and property.
339
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000340- In unittest, using a skipping decorator on a class is now equivalent to
341 skipping every test on the class. The ClassTestSuite class has been removed.
342
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000343- Issue #6050: Don't fail extracting a directory from a zipfile if
344 the directory already exists.
345
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000346- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
347 than an int, which makes some operations possible under 64-bit Linux (e.g.
348 DN_MULTISHOT with F_NOTIFY).

357 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
358 a process identifier type wider than the standard C integer type.
359

371
Antoine Pitroue4501852009-05-14 18:55:55 +0000372- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
373 library. This means, for example, that opening an UTF-16 text file in
374 append mode doesn't add a BOM at the end of the file if the file isn't
375 empty.
376
R. David Murray74b89242009-05-13 17:33:03 +0000377- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000424
425Core and Builtins
426-----------------
427
Mark Dickinson865e01a2009-05-07 16:37:01 +0000428- Issue #5914: Add new C API function PyOS_string_to_double, and
429 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
430
Eric Smith741191f2009-05-06 13:08:15 +0000431- Issue #3382: float.__format__, complex.__format__, and %-formatting
432 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
433 affects nan -> NAN and inf -> INF.
434
Mark Hammond5a607a32009-05-06 08:04:54 +0000435- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
436 in all operations, including splitdrive, split, etc. splitunc() now issues
437 a PendingDeprecation warning.
438
Eric Smith63376222009-05-05 14:04:18 +0000439- Issue #5920: For float.__format__, change the behavior with the
440 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
441 to be like 'g' but with at least one decimal point and with a
442 default precision of 12. Previously, the behavior the same but with
443 a default precision of 6. This more closely matches str(), and
444 reduces surprises when adding alignment flags to the empty
445 presentation type. This also affects the new complex.__format__ in
446 the same way.
447
Martin v. Löwis011e8422009-05-05 04:43:17 +0000448- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
449
R. David Murrayb18500d2009-05-04 22:59:07 +0000450- Issue #5890: in subclasses of 'property' the __doc__ attribute was
451 shadowed by classtype's, even if it was None. property now
452 inserts the __doc__ into the subclass instance __dict__.
453
Antoine Pitrou244651a2009-05-04 18:56:13 +0000454- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
455 sequences. Patch by Nick Barnes and Victor Stinner.
456
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000457- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000458
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000459- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
460 received a new method, detach(). detach() disconnects the underlying stream
461 from the buffer or text IO and returns it.
462
Mark Dickinson33841c32009-05-01 15:37:04 +0000463- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
464 floats with absolute value over 1e50. Also remove length
465 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
466 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000467
Eric Smith741191f2009-05-06 13:08:15 +0000468- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000469 format(complex(1, 2./3), '.5') now produces a sensible result.
470
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000471- Issue #5864: Fix empty format code formatting for floats so that it
472 never gives more than the requested number of significant digits.
473
Eric Smith6dc46f52009-04-27 20:39:49 +0000474- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
475 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
476
Eric Smithcc32a112009-04-26 21:35:14 +0000477- Issue #5835: Deprecate PyOS_ascii_formatd.
478
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000479- Issue #4971: Fix titlecase for characters that are their own
480 titlecase, but not their own uppercase.
481
Benjamin Peterson193152c2009-04-25 01:08:45 +0000482- Issue #5283: Setting __class__ in __del__ caused a segfault.
483
Mark Dickinsonad476da2009-04-23 19:14:16 +0000484- Issue #5816: complex(repr(z)) now recovers z exactly, even when
485 z involves nans, infs or negative zeros.
486
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000487- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000488
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000489- Issue #1869 (and many duplicates): make round(x, n) correctly
490 rounded for a float x, by using the decimal <-> binary conversions
491 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
492 consistently agrees with format(x, '.2f').
493
Benjamin Petersonae937c02009-04-18 20:54:08 +0000494- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
495 some builtin types.
496
Eric Smith0923d1d2009-04-16 20:16:10 +0000497- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
498
Eric Smith35e84722009-04-16 20:21:28 +0000499- Issue #5515: str.format() type 'n' combined with commas and leading
500 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000501
502- Implement PEP 378, Format Specifier for Thousands Separator, for
503 floats.
504
Mark Dickinson3370cce2009-04-17 22:40:53 +0000505- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000506 1e11, not 1e12. This avoids printing 13 significant digits in
507 situations where only 12 of them are correct. Example problem
508 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
509 long time.)
510
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000511- Issue #1580: On most platforms, use a 'short' float repr: for a
512 finite float x, repr(x) now outputs a string based on the shortest
513 sequence of decimal digits that rounds to x. Previous behaviour was
514 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000515 Another minor difference is that the new repr switches to
516 exponential notation at 1e16 instead of the previous 1e17; this
517 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000518
519 There's a new sys attribute sys.float_repr_style, which takes
520 the value 'short' to indicate that we're using short float repr,
521 and 'legacy' if the short float repr isn't available for one
522 reason or another.
523
524 The float repr change involves incorporating David Gay's 'perfect
525 rounding' code into the Python core (it's in Python/dtoa.c). As a
526 secondary consequence, all string-to-float and float-to-string
527 conversions (including all float formatting operations) will be
528 correctly rounded on these platforms.
529
530 See issue 1580 discussions for details of platforms for which
531 this change does not apply.
532
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000533- Issue #5759: float() didn't call __float__ on str subclasses.
534
Georg Brandlabc38772009-04-12 15:51:51 +0000535- The string.maketrans() function is deprecated; there is a new static method
536 maketrans() on the bytes and bytearray classes. This removes confusion about
537 the types string.maketrans() is supposed to work with, and mirrors the
538 methods available on the str class.
539
R. David Murraydc6da8a2009-04-09 22:16:43 +0000540- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
541 its clarity and its speed.
542
Matthias Klose091c7b12009-04-07 13:24:27 +0000543- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
544 to avoid compiler warnings.
545
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000546- Issue #3739: The unicode-internal encoder now reports the number of characters
547 consumed like any other encoder (instead of the number of bytes).

881
Antoine Pitrouab868312009-01-10 15:40:25 +0000882- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
883 common cases are optimized thanks to a dedicated fast path and a moderate
884 amount of loop unrolling.
885
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000886- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
887 collecting the oldest generation) so that allocating lots of objects without
888 destroying them does not show quadratic performance. Based on a proposal by
889 Martin von Löwis at
890 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
891
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000892- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000893 having been closed (for instance, a read() call could return some
894 previously buffered data). Patch by Dmitry Vasiliev.
895
Antoine Pitrou05608432009-01-09 18:53:14 +0000896- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
897 flag to work properly. Furthermore, when specifying -u, the text stdout
898 and stderr streams have line-by-line buffering enabled (the default being
899 to buffer arbitrary chunks of data).
900
Raymond Hettinger35631532009-01-09 03:58:09 +0000901- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
902 instead of ints (reducing its size from 4 to 8 times thereby reducing
903 Python's overall memory).
904
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000905- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
906 an existing .py counterpart, override the co_filename attributes of all
907 code objects if the original filename is obsolete (which can happen if the
908 file has been renamed, moved, or if it is accessed through different paths).
909 Patch by Ziga Seilnacht and Jean-Paul Calderone.
910
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000911- Issue #4580: Fix slicing of memoryviews when the item size is greater than
912 one byte. Also fixes the meaning of len() so that it returns the number of
913 items, rather than the size in bytes.
914
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000915- Issue #4075: Use OutputDebugStringW in Py_FatalError.

928
Georg Brandlccc47b62008-12-28 11:44:14 +0000929- Issue #4759: None is now allowed as the first argument of

931
Skip Montanaro80072cb2008-12-23 03:51:14 +0000932- Added test case to ensure attempts to read from a file opened for writing

939
Antoine Pitrou621601a2008-12-17 23:18:19 +0000940- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

948 failures on OS X.
949
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000950- Issue #4597: Fixed several opcodes that weren't always propagating

952
953- Issue #4589: Fixed exception handling when the __exit__ function of a

955
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000956- Issue #4445: Replace "sizeof(PyBytesObject)" with
957 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
958 bytes instances. On a typical machine this saves 3 bytes of memory
959 (on average) per allocation of a bytes instance.
960
Christian Heimesa872de52008-12-05 08:26:55 +0000961- Issue #4533: File read operation was dreadfully slow due to a slowly
962 growing read buffer. Fixed by using the same growth rate algorithm as
963 Python 2.x.
964
Antoine Pitrou5504e892008-12-06 21:27:53 +0000965- Issue #4509: Various issues surrounding resize of bytearray objects to
966 which there are buffer exports (e.g. memoryview instances).
967
Georg Brandlf9734072008-12-07 15:30:06 +0000968- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
969 method on file objects with closefd=False. The file descriptor is still
970 kept open but the file object behaves like a closed file. The ``FileIO``
971 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000972
Antoine Pitroubc420402008-12-07 20:14:49 +0000973- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +0000980- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
981 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
982 step. This avoids problems with counting UTF-8 bytes that ignores the effect
983 of using the replace error handler in PyUnicode_DecodeUTF8().

1264
Antoine Pitrou08838b62009-01-21 00:55:13 +00001265- Issue #5008: When a file is opened in append mode with the new IO library,
1266 do an explicit seek to the end of file (so that e.g. tell() returns the
1267 file size rather than 0). This is consistent with the behaviour of the
