360
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000361- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
362 of the command line.
363

367 that would raise SystemError.
368
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000369- Issue #5982: staticmethod and classmethod now expose the wrapped
370 function with __func__.
371
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000372- Added support for multiple context managers in the same with-statement.
373 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000375- Issue #5829: complex("1e500") no longer raises OverflowError. This
376 makes it consistent with float("1e500") and interpretation of real
377 and imaginary literals.
378
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000379- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

382
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000383- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
384 (1) inf and nan strings with trailing whitespace were incorrectly
385 rejected; (2) parsing of strings representing infinities and nans
386 was locale aware; and (3) the interpretation of fromhex('-nan')
387 didn't match that of float('-nan').

400 arguments for strings with a space in them.
401
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000402- collections.namedtuple() was not working with the following field
403 names: cls, self, tuple, itemgetter, and property.
404
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000405- In unittest, using a skipping decorator on a class is now equivalent to
406 skipping every test on the class. The ClassTestSuite class has been removed.
407
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000408- Issue #6050: Don't fail extracting a directory from a zipfile if
409 the directory already exists.
410
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000411- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
412 than an int, which makes some operations possible under 64-bit Linux (e.g.
413 DN_MULTISHOT with F_NOTIFY).
414
Antoine Pitrou716c4442009-05-23 19:04:03 +0000415- Issue #5761: Add the name of the underlying file to the repr() of various

419 by Musashi Tamura, tests by Marcin Bachry.
420
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000421- Issue #1983: Fix functions taking or returning a process identifier to use
422 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
423 a process identifier type wider than the standard C integer type.
424
R. David Murray87e20742009-05-23 01:30:26 +0000425- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
426 Patch by Farhan Ahmad, test by Marcin Bachry.

436
Antoine Pitroue4501852009-05-14 18:55:55 +0000437- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
438 library. This means, for example, that opening an UTF-16 text file in
439 append mode doesn't add a BOM at the end of the file if the file isn't
440 empty.
441
R. David Murray74b89242009-05-13 17:33:03 +0000442- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
443 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
444 corrects a pydoc regression.
445
R. David Murray99352742009-05-07 18:24:38 +0000446- Issue 5955: aifc's close method did not close the file it wrapped,
447 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000489
490Core and Builtins
491-----------------
492
Mark Dickinson865e01a2009-05-07 16:37:01 +0000493- Issue #5914: Add new C API function PyOS_string_to_double, and
494 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
495
Eric Smith741191f2009-05-06 13:08:15 +0000496- Issue #3382: float.__format__, complex.__format__, and %-formatting
497 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
498 affects nan -> NAN and inf -> INF.
499
Mark Hammond5a607a32009-05-06 08:04:54 +0000500- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
501 in all operations, including splitdrive, split, etc. splitunc() now issues
502 a PendingDeprecation warning.
503
Eric Smith63376222009-05-05 14:04:18 +0000504- Issue #5920: For float.__format__, change the behavior with the
505 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
506 to be like 'g' but with at least one decimal point and with a
507 default precision of 12. Previously, the behavior the same but with
508 a default precision of 6. This more closely matches str(), and
509 reduces surprises when adding alignment flags to the empty
510 presentation type. This also affects the new complex.__format__ in
511 the same way.
512
Martin v. Löwis011e8422009-05-05 04:43:17 +0000513- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
514
R. David Murrayb18500d2009-05-04 22:59:07 +0000515- Issue #5890: in subclasses of 'property' the __doc__ attribute was
516 shadowed by classtype's, even if it was None. property now
517 inserts the __doc__ into the subclass instance __dict__.
518
Antoine Pitrou244651a2009-05-04 18:56:13 +0000519- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
520 sequences. Patch by Nick Barnes and Victor Stinner.
521
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000522- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000523
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000524- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
525 received a new method, detach(). detach() disconnects the underlying stream
526 from the buffer or text IO and returns it.
527
Mark Dickinson33841c32009-05-01 15:37:04 +0000528- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
529 floats with absolute value over 1e50. Also remove length
530 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
531 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000532
Eric Smith741191f2009-05-06 13:08:15 +0000533- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000534 format(complex(1, 2./3), '.5') now produces a sensible result.
535
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000536- Issue #5864: Fix empty format code formatting for floats so that it
537 never gives more than the requested number of significant digits.
538
Eric Smith6dc46f52009-04-27 20:39:49 +0000539- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
540 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
541
Eric Smithcc32a112009-04-26 21:35:14 +0000542- Issue #5835: Deprecate PyOS_ascii_formatd.
543
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000544- Issue #4971: Fix titlecase for characters that are their own
545 titlecase, but not their own uppercase.
546
Benjamin Peterson193152c2009-04-25 01:08:45 +0000547- Issue #5283: Setting __class__ in __del__ caused a segfault.
548
Mark Dickinsonad476da2009-04-23 19:14:16 +0000549- Issue #5816: complex(repr(z)) now recovers z exactly, even when
550 z involves nans, infs or negative zeros.
551
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000552- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000553
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000554- Issue #1869 (and many duplicates): make round(x, n) correctly
555 rounded for a float x, by using the decimal <-> binary conversions
556 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
557 consistently agrees with format(x, '.2f').
558
Benjamin Petersonae937c02009-04-18 20:54:08 +0000559- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
560 some builtin types.
561
Eric Smith0923d1d2009-04-16 20:16:10 +0000562- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
563
Eric Smith35e84722009-04-16 20:21:28 +0000564- Issue #5515: str.format() type 'n' combined with commas and leading
565 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000566
567- Implement PEP 378, Format Specifier for Thousands Separator, for
568 floats.
569
Mark Dickinson3370cce2009-04-17 22:40:53 +0000570- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000571 1e11, not 1e12. This avoids printing 13 significant digits in
572 situations where only 12 of them are correct. Example problem
573 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
574 long time.)
575
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000576- Issue #1580: On most platforms, use a 'short' float repr: for a
577 finite float x, repr(x) now outputs a string based on the shortest
578 sequence of decimal digits that rounds to x. Previous behaviour was
579 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000580 Another minor difference is that the new repr switches to
581 exponential notation at 1e16 instead of the previous 1e17; this
582 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000583
584 There's a new sys attribute sys.float_repr_style, which takes
585 the value 'short' to indicate that we're using short float repr,
586 and 'legacy' if the short float repr isn't available for one
587 reason or another.
588
589 The float repr change involves incorporating David Gay's 'perfect
590 rounding' code into the Python core (it's in Python/dtoa.c). As a
591 secondary consequence, all string-to-float and float-to-string
592 conversions (including all float formatting operations) will be
593 correctly rounded on these platforms.
594
595 See issue 1580 discussions for details of platforms for which
596 this change does not apply.
597
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000598- Issue #5759: float() didn't call __float__ on str subclasses.
599
Georg Brandlabc38772009-04-12 15:51:51 +0000600- The string.maketrans() function is deprecated; there is a new static method
601 maketrans() on the bytes and bytearray classes. This removes confusion about
602 the types string.maketrans() is supposed to work with, and mirrors the
603 methods available on the str class.
604
R. David Murraydc6da8a2009-04-09 22:16:43 +0000605- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
606 its clarity and its speed.
607
Matthias Klose091c7b12009-04-07 13:24:27 +0000608- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
609 to avoid compiler warnings.
610
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000611- Issue #3739: The unicode-internal encoder now reports the number of characters
612 consumed like any other encoder (instead of the number of bytes).

Martin v. Löwis403117a2009-05-24 19:19:17 +0000622- Issue #5311: bdist_msi can now build packages that do not depend on a
623 specific Python version.
624
Raymond Hettingereb816952009-05-29 01:22:18 +0000625- Issue #5150: IDLE's format menu now has an option to strip trailing

Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000932- Issue #4935: The overflow checking code in the expandtabs() method common
933 to str, bytes and bytearray could be optimized away by the compiler, letting
934 the interpreter segfault instead of raising an error.
935
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000936- Issue #3720: Fix a crash when an iterator modifies its class and removes its
937 __next__ method.
938
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000939- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
940 function no longer attempt to call the __long__ slot to convert an object
941 to an integer. Only the __int__ and __trunc__ slots are examined.

946
Antoine Pitrouab868312009-01-10 15:40:25 +0000947- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
948 common cases are optimized thanks to a dedicated fast path and a moderate
949 amount of loop unrolling.
950
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000951- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
952 collecting the oldest generation) so that allocating lots of objects without
953 destroying them does not show quadratic performance. Based on a proposal by
954 Martin von Löwis at
955 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
956
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000957- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000958 having been closed (for instance, a read() call could return some
959 previously buffered data). Patch by Dmitry Vasiliev.
960
Antoine Pitrou05608432009-01-09 18:53:14 +0000961- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
962 flag to work properly. Furthermore, when specifying -u, the text stdout
963 and stderr streams have line-by-line buffering enabled (the default being
964 to buffer arbitrary chunks of data).
965
Raymond Hettinger35631532009-01-09 03:58:09 +0000966- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
967 instead of ints (reducing its size from 4 to 8 times thereby reducing
968 Python's overall memory).
969
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000970- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
971 an existing .py counterpart, override the co_filename attributes of all
972 code objects if the original filename is obsolete (which can happen if the
973 file has been renamed, moved, or if it is accessed through different paths).
974 Patch by Ziga Seilnacht and Jean-Paul Calderone.
975
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000976- Issue #4580: Fix slicing of memoryviews when the item size is greater than
977 one byte. Also fixes the meaning of len() so that it returns the number of
978 items, rather than the size in bytes.
979
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000980- Issue #4075: Use OutputDebugStringW in Py_FatalError.
981
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000982- Issue #4747: When the terminal does not use utf-8, executing a script with
983 non-ascii characters in its name could fail with a "SyntaxError: None" error.
984
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000985- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

Antoine Pitrou7ddda782009-01-01 15:35:33 +0000988- Issue #3680: Reference cycles created through a dict, set or deque iterator
989 did not get collected.
990
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000991- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
992 where the tp_hash and tp_dict slots are both NULL.
993
Georg Brandlccc47b62008-12-28 11:44:14 +0000994- Issue #4759: None is now allowed as the first argument of
995 bytearray.translate(). It was always allowed for bytes.translate().
996
Skip Montanaro80072cb2008-12-23 03:51:14 +0000997- Added test case to ensure attempts to read from a file opened for writing
998 fail.
999
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001000- Issue #3106: Speedup some comparisons (str/str and int/int).

1004
Antoine Pitrou621601a2008-12-17 23:18:19 +00001005- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1007 unreachable. Original patch by Neil Schemenauer.
1008
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001009- Issue #3439: Add a bit_length method to int.
1010
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001011- Issue #2173: When getting device encoding, check that return value of
1012 nl_langinfo is not the empty string. This was causing silent build
1013 failures on OS X.
1014
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001015- Issue #4597: Fixed several opcodes that weren't always propagating
1016 exceptions.
1017
1018- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001019 context manager returns a value that cannot be converted to a bool.
1020
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001021- Issue #4445: Replace "sizeof(PyBytesObject)" with
1022 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1023 bytes instances. On a typical machine this saves 3 bytes of memory
1024 (on average) per allocation of a bytes instance.
1025
Christian Heimesa872de52008-12-05 08:26:55 +00001026- Issue #4533: File read operation was dreadfully slow due to a slowly
1027 growing read buffer. Fixed by using the same growth rate algorithm as
1028 Python 2.x.
1029
Antoine Pitrou5504e892008-12-06 21:27:53 +00001030- Issue #4509: Various issues surrounding resize of bytearray objects to
1031 which there are buffer exports (e.g. memoryview instances).
1032
Georg Brandlf9734072008-12-07 15:30:06 +00001033- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1034 method on file objects with closefd=False. The file descriptor is still
1035 kept open but the file object behaves like a closed file. The ``FileIO``
1036 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001037
Antoine Pitroubc420402008-12-07 20:14:49 +00001038- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1044
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001045- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1046 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1047 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1048 of using the replace error handler in PyUnicode_DecodeUTF8().

Tarek Ziadéf8926b22009-07-16 16:18:19 +00001067- Issue #6466: now distutils.cygwinccompiler and distutils.emxccompiler
1068 uses the same refactored function to get gcc/ld/dllwrap versions numbers.

1497 doesn't configure logging.
