340
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000341- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
342 of the command line.
343
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000344- Issue #6012: Add cleanup support to O& argument parsing.

Eric Smith41669ca2009-05-23 14:23:22 +0000346- Issue #6089: Fixed str.format with certain invalid field specifiers
347 that would raise SystemError.
348
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000349- Issue #5982: staticmethod and classmethod now expose the wrapped
350 function with __func__.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000355- Issue #5829: complex("1e500") no longer raises OverflowError. This
356 makes it consistent with float("1e500") and interpretation of real
357 and imaginary literals.
358
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000359- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

362
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000363- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
364 (1) inf and nan strings with trailing whitespace were incorrectly
365 rejected; (2) parsing of strings representing infinities and nans
366 was locale aware; and (3) the interpretation of fromhex('-nan')
367 didn't match that of float('-nan').

383 names: cls, self, tuple, itemgetter, and property.
384
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000385- In unittest, using a skipping decorator on a class is now equivalent to
386 skipping every test on the class. The ClassTestSuite class has been removed.
387
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000388- Issue #6050: Don't fail extracting a directory from a zipfile if
389 the directory already exists.
390
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000391- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
392 than an int, which makes some operations possible under 64-bit Linux (e.g.
393 DN_MULTISHOT with F_NOTIFY).
394
Antoine Pitrou716c4442009-05-23 19:04:03 +0000395- Issue #5761: Add the name of the underlying file to the repr() of various

399 by Musashi Tamura, tests by Marcin Bachry.
400
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000401- Issue #1983: Fix functions taking or returning a process identifier to use
402 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
403 a process identifier type wider than the standard C integer type.
404
R. David Murray87e20742009-05-23 01:30:26 +0000405- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

416
Antoine Pitroue4501852009-05-14 18:55:55 +0000417- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
418 library. This means, for example, that opening an UTF-16 text file in
419 append mode doesn't add a BOM at the end of the file if the file isn't
420 empty.
421
R. David Murray74b89242009-05-13 17:33:03 +0000422- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
423 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
424 corrects a pydoc regression.
425
R. David Murray99352742009-05-07 18:24:38 +0000426- Issue 5955: aifc's close method did not close the file it wrapped,
427 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000469
470Core and Builtins
471-----------------
472
Mark Dickinson865e01a2009-05-07 16:37:01 +0000473- Issue #5914: Add new C API function PyOS_string_to_double, and
474 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
475
Eric Smith741191f2009-05-06 13:08:15 +0000476- Issue #3382: float.__format__, complex.__format__, and %-formatting
477 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
478 affects nan -> NAN and inf -> INF.
479
Mark Hammond5a607a32009-05-06 08:04:54 +0000480- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
481 in all operations, including splitdrive, split, etc. splitunc() now issues
482 a PendingDeprecation warning.
483
Eric Smith63376222009-05-05 14:04:18 +0000484- Issue #5920: For float.__format__, change the behavior with the
485 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
486 to be like 'g' but with at least one decimal point and with a
487 default precision of 12. Previously, the behavior the same but with
488 a default precision of 6. This more closely matches str(), and
489 reduces surprises when adding alignment flags to the empty
490 presentation type. This also affects the new complex.__format__ in
491 the same way.
492
Martin v. Löwis011e8422009-05-05 04:43:17 +0000493- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
494
R. David Murrayb18500d2009-05-04 22:59:07 +0000495- Issue #5890: in subclasses of 'property' the __doc__ attribute was
496 shadowed by classtype's, even if it was None. property now
497 inserts the __doc__ into the subclass instance __dict__.
498
Antoine Pitrou244651a2009-05-04 18:56:13 +0000499- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
500 sequences. Patch by Nick Barnes and Victor Stinner.
501
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000502- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000503
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000504- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
505 received a new method, detach(). detach() disconnects the underlying stream
506 from the buffer or text IO and returns it.
507
Mark Dickinson33841c32009-05-01 15:37:04 +0000508- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
509 floats with absolute value over 1e50. Also remove length
510 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
511 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000512
Eric Smith741191f2009-05-06 13:08:15 +0000513- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000514 format(complex(1, 2./3), '.5') now produces a sensible result.
515
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000516- Issue #5864: Fix empty format code formatting for floats so that it
517 never gives more than the requested number of significant digits.
518
Eric Smith6dc46f52009-04-27 20:39:49 +0000519- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
520 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
521
Eric Smithcc32a112009-04-26 21:35:14 +0000522- Issue #5835: Deprecate PyOS_ascii_formatd.
523
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000524- Issue #4971: Fix titlecase for characters that are their own
525 titlecase, but not their own uppercase.
526
Benjamin Peterson193152c2009-04-25 01:08:45 +0000527- Issue #5283: Setting __class__ in __del__ caused a segfault.
528
Mark Dickinsonad476da2009-04-23 19:14:16 +0000529- Issue #5816: complex(repr(z)) now recovers z exactly, even when
530 z involves nans, infs or negative zeros.
531
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000532- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000533
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000534- Issue #1869 (and many duplicates): make round(x, n) correctly
535 rounded for a float x, by using the decimal <-> binary conversions
536 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
537 consistently agrees with format(x, '.2f').
538
Benjamin Petersonae937c02009-04-18 20:54:08 +0000539- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
540 some builtin types.
541
Eric Smith0923d1d2009-04-16 20:16:10 +0000542- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
543
Eric Smith35e84722009-04-16 20:21:28 +0000544- Issue #5515: str.format() type 'n' combined with commas and leading
545 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000546
547- Implement PEP 378, Format Specifier for Thousands Separator, for
548 floats.
549
Mark Dickinson3370cce2009-04-17 22:40:53 +0000550- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000551 1e11, not 1e12. This avoids printing 13 significant digits in
552 situations where only 12 of them are correct. Example problem
553 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
554 long time.)
555
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000556- Issue #1580: On most platforms, use a 'short' float repr: for a
557 finite float x, repr(x) now outputs a string based on the shortest
558 sequence of decimal digits that rounds to x. Previous behaviour was
559 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000560 Another minor difference is that the new repr switches to
561 exponential notation at 1e16 instead of the previous 1e17; this
562 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000563
564 There's a new sys attribute sys.float_repr_style, which takes
565 the value 'short' to indicate that we're using short float repr,
566 and 'legacy' if the short float repr isn't available for one
567 reason or another.
568
569 The float repr change involves incorporating David Gay's 'perfect
570 rounding' code into the Python core (it's in Python/dtoa.c). As a
571 secondary consequence, all string-to-float and float-to-string
572 conversions (including all float formatting operations) will be
573 correctly rounded on these platforms.
574
575 See issue 1580 discussions for details of platforms for which
576 this change does not apply.
577
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000578- Issue #5759: float() didn't call __float__ on str subclasses.
579
Georg Brandlabc38772009-04-12 15:51:51 +0000580- The string.maketrans() function is deprecated; there is a new static method
581 maketrans() on the bytes and bytearray classes. This removes confusion about
582 the types string.maketrans() is supposed to work with, and mirrors the
583 methods available on the str class.
584
R. David Murraydc6da8a2009-04-09 22:16:43 +0000585- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
586 its clarity and its speed.
587
Matthias Klose091c7b12009-04-07 13:24:27 +0000588- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
589 to avoid compiler warnings.
590
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000591- Issue #3739: The unicode-internal encoder now reports the number of characters
592 consumed like any other encoder (instead of the number of bytes).

932 collecting the oldest generation) so that allocating lots of objects without
933 destroying them does not show quadratic performance. Based on a proposal by
934 Martin von Löwis at
935 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
936
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000937- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000938 having been closed (for instance, a read() call could return some
939 previously buffered data). Patch by Dmitry Vasiliev.
940
Antoine Pitrou05608432009-01-09 18:53:14 +0000941- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
942 flag to work properly. Furthermore, when specifying -u, the text stdout
943 and stderr streams have line-by-line buffering enabled (the default being
944 to buffer arbitrary chunks of data).
945
Raymond Hettinger35631532009-01-09 03:58:09 +0000946- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
947 instead of ints (reducing its size from 4 to 8 times thereby reducing
948 Python's overall memory).
949
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000950- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
951 an existing .py counterpart, override the co_filename attributes of all
952 code objects if the original filename is obsolete (which can happen if the
953 file has been renamed, moved, or if it is accessed through different paths).
954 Patch by Ziga Seilnacht and Jean-Paul Calderone.
955
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000956- Issue #4580: Fix slicing of memoryviews when the item size is greater than
957 one byte. Also fixes the meaning of len() so that it returns the number of
958 items, rather than the size in bytes.
959
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000960- Issue #4075: Use OutputDebugStringW in Py_FatalError.
961
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000962- Issue #4747: When the terminal does not use utf-8, executing a script with
963 non-ascii characters in its name could fail with a "SyntaxError: None" error.
964
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000965- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000967
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000968- Issue #3680: Reference cycles created through a dict, set or deque iterator
969 did not get collected.
970
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000971- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
972 where the tp_hash and tp_dict slots are both NULL.
973
Georg Brandlccc47b62008-12-28 11:44:14 +0000974- Issue #4759: None is now allowed as the first argument of
975 bytearray.translate(). It was always allowed for bytes.translate().
976
Skip Montanaro80072cb2008-12-23 03:51:14 +0000977- Added test case to ensure attempts to read from a file opened for writing
978 fail.
979

981
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000982- Issue #2183: Simplify and optimize bytecode for list, dict and set
983 comprehensions. Original patch for list comprehensions by Neal Norwitz.
984
Antoine Pitrou621601a2008-12-17 23:18:19 +0000985- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
986 print elapsed times, not only when some objects are uncollectable /
987 unreachable. Original patch by Neil Schemenauer.
988

990
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000991- Issue #2173: When getting device encoding, check that return value of
992 nl_langinfo is not the empty string. This was causing silent build
993 failures on OS X.
994
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000995- Issue #4597: Fixed several opcodes that weren't always propagating
996 exceptions.
997
998- Issue #4589: Fixed exception handling when the __exit__ function of a

1000
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001001- Issue #4445: Replace "sizeof(PyBytesObject)" with
1002 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1003 bytes instances. On a typical machine this saves 3 bytes of memory
1004 (on average) per allocation of a bytes instance.
1005
Christian Heimesa872de52008-12-05 08:26:55 +00001006- Issue #4533: File read operation was dreadfully slow due to a slowly
1007 growing read buffer. Fixed by using the same growth rate algorithm as
1008 Python 2.x.
1009
Antoine Pitrou5504e892008-12-06 21:27:53 +00001010- Issue #4509: Various issues surrounding resize of bytearray objects to
1011 which there are buffer exports (e.g. memoryview instances).
1012
Georg Brandlf9734072008-12-07 15:30:06 +00001013- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1014 method on file objects with closefd=False. The file descriptor is still
1015 kept open but the file object behaves like a closed file. The ``FileIO``
1016 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001018- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1019 larger than 1.

1024
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001025- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1026 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1027 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1028 of using the replace error handler in PyUnicode_DecodeUTF8().

1044 uses the same refactored function to get gcc/ld/dllwrap versions numbers.

Antoine Pitrou08838b62009-01-21 00:55:13 +00001333- Issue #5008: When a file is opened in append mode with the new IO library,
1334 do an explicit seek to the end of file (so that e.g. tell() returns the
