363 that would raise SystemError.
364
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000365- Issue #5982: staticmethod and classmethod now expose the wrapped
366 function with __func__.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000371- Issue #5829: complex("1e500") no longer raises OverflowError. This
372 makes it consistent with float("1e500") and interpretation of real
373 and imaginary literals.
374
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000375- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

378
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000379- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
380 (1) inf and nan strings with trailing whitespace were incorrectly
381 rejected; (2) parsing of strings representing infinities and nans
382 was locale aware; and (3) the interpretation of fromhex('-nan')
383 didn't match that of float('-nan').

399 names: cls, self, tuple, itemgetter, and property.
400
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000401- In unittest, using a skipping decorator on a class is now equivalent to
402 skipping every test on the class. The ClassTestSuite class has been removed.
403
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000404- Issue #6050: Don't fail extracting a directory from a zipfile if
405 the directory already exists.
406
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000407- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
408 than an int, which makes some operations possible under 64-bit Linux (e.g.
409 DN_MULTISHOT with F_NOTIFY).

416
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000417- Issue #1983: Fix functions taking or returning a process identifier to use
418 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
419 a process identifier type wider than the standard C integer type.
420
R. David Murray87e20742009-05-23 01:30:26 +0000421- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

432
Antoine Pitroue4501852009-05-14 18:55:55 +0000433- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
434 library. This means, for example, that opening an UTF-16 text file in
435 append mode doesn't add a BOM at the end of the file if the file isn't
436 empty.
437
R. David Murray74b89242009-05-13 17:33:03 +0000438- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
439 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
440 corrects a pydoc regression.
441
R. David Murray99352742009-05-07 18:24:38 +0000442- Issue 5955: aifc's close method did not close the file it wrapped,
443 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000485
486Core and Builtins
487-----------------
488
Mark Dickinson865e01a2009-05-07 16:37:01 +0000489- Issue #5914: Add new C API function PyOS_string_to_double, and
490 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
491
Eric Smith741191f2009-05-06 13:08:15 +0000492- Issue #3382: float.__format__, complex.__format__, and %-formatting
493 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
494 affects nan -> NAN and inf -> INF.
495
Mark Hammond5a607a32009-05-06 08:04:54 +0000496- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
497 in all operations, including splitdrive, split, etc. splitunc() now issues
498 a PendingDeprecation warning.
499
Eric Smith63376222009-05-05 14:04:18 +0000500- Issue #5920: For float.__format__, change the behavior with the
501 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
502 to be like 'g' but with at least one decimal point and with a
503 default precision of 12. Previously, the behavior the same but with
504 a default precision of 6. This more closely matches str(), and
505 reduces surprises when adding alignment flags to the empty
506 presentation type. This also affects the new complex.__format__ in
507 the same way.
508
Martin v. Löwis011e8422009-05-05 04:43:17 +0000509- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
510
R. David Murrayb18500d2009-05-04 22:59:07 +0000511- Issue #5890: in subclasses of 'property' the __doc__ attribute was
512 shadowed by classtype's, even if it was None. property now
513 inserts the __doc__ into the subclass instance __dict__.
514
Antoine Pitrou244651a2009-05-04 18:56:13 +0000515- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
516 sequences. Patch by Nick Barnes and Victor Stinner.
517
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000518- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000519
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000520- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
521 received a new method, detach(). detach() disconnects the underlying stream
522 from the buffer or text IO and returns it.
523
Mark Dickinson33841c32009-05-01 15:37:04 +0000524- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
525 floats with absolute value over 1e50. Also remove length
526 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
527 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000528
Eric Smith741191f2009-05-06 13:08:15 +0000529- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000530 format(complex(1, 2./3), '.5') now produces a sensible result.
531
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000532- Issue #5864: Fix empty format code formatting for floats so that it
533 never gives more than the requested number of significant digits.
534
Eric Smith6dc46f52009-04-27 20:39:49 +0000535- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
536 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
537
Eric Smithcc32a112009-04-26 21:35:14 +0000538- Issue #5835: Deprecate PyOS_ascii_formatd.
539
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000540- Issue #4971: Fix titlecase for characters that are their own
541 titlecase, but not their own uppercase.
542
Benjamin Peterson193152c2009-04-25 01:08:45 +0000543- Issue #5283: Setting __class__ in __del__ caused a segfault.
544
Mark Dickinsonad476da2009-04-23 19:14:16 +0000545- Issue #5816: complex(repr(z)) now recovers z exactly, even when
546 z involves nans, infs or negative zeros.
547
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000548- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000549
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000550- Issue #1869 (and many duplicates): make round(x, n) correctly
551 rounded for a float x, by using the decimal <-> binary conversions
552 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
553 consistently agrees with format(x, '.2f').
554
Benjamin Petersonae937c02009-04-18 20:54:08 +0000555- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
556 some builtin types.
557
Eric Smith0923d1d2009-04-16 20:16:10 +0000558- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
559
Eric Smith35e84722009-04-16 20:21:28 +0000560- Issue #5515: str.format() type 'n' combined with commas and leading
561 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000562
563- Implement PEP 378, Format Specifier for Thousands Separator, for
564 floats.
565
Mark Dickinson3370cce2009-04-17 22:40:53 +0000566- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000567 1e11, not 1e12. This avoids printing 13 significant digits in
568 situations where only 12 of them are correct. Example problem
569 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
570 long time.)
571
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000572- Issue #1580: On most platforms, use a 'short' float repr: for a
573 finite float x, repr(x) now outputs a string based on the shortest
574 sequence of decimal digits that rounds to x. Previous behaviour was
575 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000576 Another minor difference is that the new repr switches to
577 exponential notation at 1e16 instead of the previous 1e17; this
578 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000579
580 There's a new sys attribute sys.float_repr_style, which takes
581 the value 'short' to indicate that we're using short float repr,
582 and 'legacy' if the short float repr isn't available for one
583 reason or another.
584
585 The float repr change involves incorporating David Gay's 'perfect
586 rounding' code into the Python core (it's in Python/dtoa.c). As a
587 secondary consequence, all string-to-float and float-to-string
588 conversions (including all float formatting operations) will be
589 correctly rounded on these platforms.
590
591 See issue 1580 discussions for details of platforms for which
592 this change does not apply.
593
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000594- Issue #5759: float() didn't call __float__ on str subclasses.
595
Georg Brandlabc38772009-04-12 15:51:51 +0000596- The string.maketrans() function is deprecated; there is a new static method
597 maketrans() on the bytes and bytearray classes. This removes confusion about
598 the types string.maketrans() is supposed to work with, and mirrors the
599 methods available on the str class.
600
R. David Murraydc6da8a2009-04-09 22:16:43 +0000601- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
602 its clarity and its speed.
603
Matthias Klose091c7b12009-04-07 13:24:27 +0000604- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
605 to avoid compiler warnings.
606
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000607- Issue #3739: The unicode-internal encoder now reports the number of characters
608 consumed like any other encoder (instead of the number of bytes).

Martin v. Löwis403117a2009-05-24 19:19:17 +0000618- Issue #5311: bdist_msi can now build packages that do not depend on a
619 specific Python version.
620
Raymond Hettingereb816952009-05-29 01:22:18 +0000621- Issue #5150: IDLE's format menu now has an option to strip trailing

623
Vinay Sajipaffbd872009-06-11 10:11:47 +0000624- Issue #5940: distutils.command.build_clib.check_library_list was not doing

Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000932- Issue #3720: Fix a crash when an iterator modifies its class and removes its
933 __next__ method.
934
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000935- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
936 function no longer attempt to call the __long__ slot to convert an object
937 to an integer. Only the __int__ and __trunc__ slots are examined.

942
Antoine Pitrouab868312009-01-10 15:40:25 +0000943- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
944 common cases are optimized thanks to a dedicated fast path and a moderate
945 amount of loop unrolling.
946
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000947- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
948 collecting the oldest generation) so that allocating lots of objects without
949 destroying them does not show quadratic performance. Based on a proposal by
950 Martin von Löwis at
951 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
952
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000953- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000954 having been closed (for instance, a read() call could return some
955 previously buffered data). Patch by Dmitry Vasiliev.
956
Antoine Pitrou05608432009-01-09 18:53:14 +0000957- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
958 flag to work properly. Furthermore, when specifying -u, the text stdout
959 and stderr streams have line-by-line buffering enabled (the default being
960 to buffer arbitrary chunks of data).
961
Raymond Hettinger35631532009-01-09 03:58:09 +0000962- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
963 instead of ints (reducing its size from 4 to 8 times thereby reducing
964 Python's overall memory).
965
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000966- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
967 an existing .py counterpart, override the co_filename attributes of all
968 code objects if the original filename is obsolete (which can happen if the
969 file has been renamed, moved, or if it is accessed through different paths).
970 Patch by Ziga Seilnacht and Jean-Paul Calderone.
971
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000972- Issue #4580: Fix slicing of memoryviews when the item size is greater than
973 one byte. Also fixes the meaning of len() so that it returns the number of
974 items, rather than the size in bytes.
975
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000976- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000978- Issue #4747: When the terminal does not use utf-8, executing a script with
979 non-ascii characters in its name could fail with a "SyntaxError: None" error.
980

985 did not get collected.
986
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000987- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
988 where the tp_hash and tp_dict slots are both NULL.
989
Georg Brandlccc47b62008-12-28 11:44:14 +0000990- Issue #4759: None is now allowed as the first argument of
991 bytearray.translate(). It was always allowed for bytes.translate().
992
Skip Montanaro80072cb2008-12-23 03:51:14 +0000993- Added test case to ensure attempts to read from a file opened for writing
994 fail.

1000
Antoine Pitrou621601a2008-12-17 23:18:19 +00001001- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1009 failures on OS X.
1010
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001011- Issue #4597: Fixed several opcodes that weren't always propagating
1012 exceptions.
1013
1014- Issue #4589: Fixed exception handling when the __exit__ function of a

1016
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001017- Issue #4445: Replace "sizeof(PyBytesObject)" with
1018 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1019 bytes instances. On a typical machine this saves 3 bytes of memory
1020 (on average) per allocation of a bytes instance.
1021
Christian Heimesa872de52008-12-05 08:26:55 +00001022- Issue #4533: File read operation was dreadfully slow due to a slowly
1023 growing read buffer. Fixed by using the same growth rate algorithm as
1024 Python 2.x.
1025
Antoine Pitrou5504e892008-12-06 21:27:53 +00001026- Issue #4509: Various issues surrounding resize of bytearray objects to
1027 which there are buffer exports (e.g. memoryview instances).
1028
Georg Brandlf9734072008-12-07 15:30:06 +00001029- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1030 method on file objects with closefd=False. The file descriptor is still
1031 kept open but the file object behaves like a closed file. The ``FileIO``
1032 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001033
Antoine Pitroubc420402008-12-07 20:14:49 +00001034- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1040
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001041- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1042 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1043 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1044 of using the replace error handler in PyUnicode_DecodeUTF8().

Tarek Ziadéf8926b22009-07-16 16:18:19 +00001063- Issue #6466: now distutils.cygwinccompiler and distutils.emxccompiler
1064 uses the same refactored function to get gcc/ld/dllwrap versions numbers.

1354 do an explicit seek to the end of file (so that e.g. tell() returns the
