336Core and Builtins
337-----------------
338
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000339- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
340 of the command line.
341
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000342- Issue #6012: Add cleanup support to O& argument parsing.
343
Eric Smith41669ca2009-05-23 14:23:22 +0000344- Issue #6089: Fixed str.format with certain invalid field specifiers
345 that would raise SystemError.
346
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000347- Issue #5982: staticmethod and classmethod now expose the wrapped
348 function with __func__.
349
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000350- Added support for multiple context managers in the same with-statement.
351 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000352
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000353- Issue #5829: complex("1e500") no longer raises OverflowError. This
354 makes it consistent with float("1e500") and interpretation of real
355 and imaginary literals.
356
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000357- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

360
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000361- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
362 (1) inf and nan strings with trailing whitespace were incorrectly
363 rejected; (2) parsing of strings representing infinities and nans
364 was locale aware; and (3) the interpretation of fromhex('-nan')
365 didn't match that of float('-nan').

373
R. David Murray1f1b9d32009-05-27 20:56:59 +0000374- Issue #6121: pydoc now ignores leading and trailing spaces in the
375 argument to the 'help' function.
376
Georg Brandlfaf41492009-05-26 18:31:11 +0000377- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
378 arguments for strings with a space in them.
379
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000380- collections.namedtuple() was not working with the following field
381 names: cls, self, tuple, itemgetter, and property.
382
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000383- In unittest, using a skipping decorator on a class is now equivalent to
384 skipping every test on the class. The ClassTestSuite class has been removed.
385
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000386- Issue #6050: Don't fail extracting a directory from a zipfile if
387 the directory already exists.
388
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000389- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
390 than an int, which makes some operations possible under 64-bit Linux (e.g.
391 DN_MULTISHOT with F_NOTIFY).
392
Antoine Pitrou716c4442009-05-23 19:04:03 +0000393- Issue #5761: Add the name of the underlying file to the repr() of various

397 by Musashi Tamura, tests by Marcin Bachry.
398
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000399- Issue #1983: Fix functions taking or returning a process identifier to use
400 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
401 a process identifier type wider than the standard C integer type.
402
R. David Murray87e20742009-05-23 01:30:26 +0000403- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
404 Patch by Farhan Ahmad, test by Marcin Bachry.

414
Antoine Pitroue4501852009-05-14 18:55:55 +0000415- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
416 library. This means, for example, that opening an UTF-16 text file in
417 append mode doesn't add a BOM at the end of the file if the file isn't
418 empty.
419
R. David Murray74b89242009-05-13 17:33:03 +0000420- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
421 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
422 corrects a pydoc regression.
423
R. David Murray99352742009-05-07 18:24:38 +0000424- Issue 5955: aifc's close method did not close the file it wrapped,
425 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000467
468Core and Builtins
469-----------------
470
Mark Dickinson865e01a2009-05-07 16:37:01 +0000471- Issue #5914: Add new C API function PyOS_string_to_double, and
472 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
473
Eric Smith741191f2009-05-06 13:08:15 +0000474- Issue #3382: float.__format__, complex.__format__, and %-formatting
475 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
476 affects nan -> NAN and inf -> INF.
477
Mark Hammond5a607a32009-05-06 08:04:54 +0000478- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
479 in all operations, including splitdrive, split, etc. splitunc() now issues
480 a PendingDeprecation warning.
481
Eric Smith63376222009-05-05 14:04:18 +0000482- Issue #5920: For float.__format__, change the behavior with the
483 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
484 to be like 'g' but with at least one decimal point and with a
485 default precision of 12. Previously, the behavior the same but with
486 a default precision of 6. This more closely matches str(), and
487 reduces surprises when adding alignment flags to the empty
488 presentation type. This also affects the new complex.__format__ in
489 the same way.
490
Martin v. Löwis011e8422009-05-05 04:43:17 +0000491- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
492
R. David Murrayb18500d2009-05-04 22:59:07 +0000493- Issue #5890: in subclasses of 'property' the __doc__ attribute was
494 shadowed by classtype's, even if it was None. property now
495 inserts the __doc__ into the subclass instance __dict__.
496
Antoine Pitrou244651a2009-05-04 18:56:13 +0000497- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
498 sequences. Patch by Nick Barnes and Victor Stinner.
499
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000500- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000501
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000502- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
503 received a new method, detach(). detach() disconnects the underlying stream
504 from the buffer or text IO and returns it.
505
Mark Dickinson33841c32009-05-01 15:37:04 +0000506- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
507 floats with absolute value over 1e50. Also remove length
508 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
509 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000510
Eric Smith741191f2009-05-06 13:08:15 +0000511- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000512 format(complex(1, 2./3), '.5') now produces a sensible result.
513
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000514- Issue #5864: Fix empty format code formatting for floats so that it
515 never gives more than the requested number of significant digits.
516
Eric Smith6dc46f52009-04-27 20:39:49 +0000517- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
518 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
519
Eric Smithcc32a112009-04-26 21:35:14 +0000520- Issue #5835: Deprecate PyOS_ascii_formatd.
521
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000522- Issue #4971: Fix titlecase for characters that are their own
523 titlecase, but not their own uppercase.
524
Benjamin Peterson193152c2009-04-25 01:08:45 +0000525- Issue #5283: Setting __class__ in __del__ caused a segfault.
526
Mark Dickinsonad476da2009-04-23 19:14:16 +0000527- Issue #5816: complex(repr(z)) now recovers z exactly, even when
528 z involves nans, infs or negative zeros.
529
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000530- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000531
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000532- Issue #1869 (and many duplicates): make round(x, n) correctly
533 rounded for a float x, by using the decimal <-> binary conversions
534 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
535 consistently agrees with format(x, '.2f').
536
Benjamin Petersonae937c02009-04-18 20:54:08 +0000537- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
538 some builtin types.
539
Eric Smith0923d1d2009-04-16 20:16:10 +0000540- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
541
Eric Smith35e84722009-04-16 20:21:28 +0000542- Issue #5515: str.format() type 'n' combined with commas and leading
543 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000544
545- Implement PEP 378, Format Specifier for Thousands Separator, for
546 floats.
547
Mark Dickinson3370cce2009-04-17 22:40:53 +0000548- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000549 1e11, not 1e12. This avoids printing 13 significant digits in
550 situations where only 12 of them are correct. Example problem
551 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
552 long time.)
553
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000554- Issue #1580: On most platforms, use a 'short' float repr: for a
555 finite float x, repr(x) now outputs a string based on the shortest
556 sequence of decimal digits that rounds to x. Previous behaviour was
557 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000558 Another minor difference is that the new repr switches to
559 exponential notation at 1e16 instead of the previous 1e17; this
560 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000561
562 There's a new sys attribute sys.float_repr_style, which takes
563 the value 'short' to indicate that we're using short float repr,
564 and 'legacy' if the short float repr isn't available for one
565 reason or another.
566
567 The float repr change involves incorporating David Gay's 'perfect
568 rounding' code into the Python core (it's in Python/dtoa.c). As a
569 secondary consequence, all string-to-float and float-to-string
570 conversions (including all float formatting operations) will be
571 correctly rounded on these platforms.
572
573 See issue 1580 discussions for details of platforms for which
574 this change does not apply.
575
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000576- Issue #5759: float() didn't call __float__ on str subclasses.
577
Georg Brandlabc38772009-04-12 15:51:51 +0000578- The string.maketrans() function is deprecated; there is a new static method
579 maketrans() on the bytes and bytearray classes. This removes confusion about
580 the types string.maketrans() is supposed to work with, and mirrors the
581 methods available on the str class.
582
R. David Murraydc6da8a2009-04-09 22:16:43 +0000583- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
584 its clarity and its speed.
585
Matthias Klose091c7b12009-04-07 13:24:27 +0000586- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
587 to avoid compiler warnings.
588
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000589- Issue #3739: The unicode-internal encoder now reports the number of characters
590 consumed like any other encoder (instead of the number of bytes).

605
Vinay Sajipaffbd872009-06-11 10:11:47 +0000606- Issue #5940: distutils.command.build_clib.check_library_list was not doing

Vinay Sajip6268cbc2009-01-21 00:19:28 +0000935- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000936 having been closed (for instance, a read() call could return some
937 previously buffered data). Patch by Dmitry Vasiliev.
938
Antoine Pitrou05608432009-01-09 18:53:14 +0000939- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
940 flag to work properly. Furthermore, when specifying -u, the text stdout
941 and stderr streams have line-by-line buffering enabled (the default being
942 to buffer arbitrary chunks of data).
943
Raymond Hettinger35631532009-01-09 03:58:09 +0000944- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
945 instead of ints (reducing its size from 4 to 8 times thereby reducing
946 Python's overall memory).
947
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000948- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
949 an existing .py counterpart, override the co_filename attributes of all
950 code objects if the original filename is obsolete (which can happen if the
951 file has been renamed, moved, or if it is accessed through different paths).
952 Patch by Ziga Seilnacht and Jean-Paul Calderone.
953
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000954- Issue #4580: Fix slicing of memoryviews when the item size is greater than
955 one byte. Also fixes the meaning of len() so that it returns the number of
956 items, rather than the size in bytes.
957
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000958- Issue #4075: Use OutputDebugStringW in Py_FatalError.
959
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000960- Issue #4747: When the terminal does not use utf-8, executing a script with
961 non-ascii characters in its name could fail with a "SyntaxError: None" error.
962
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000963- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +0000964 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000965
Antoine Pitrou7ddda782009-01-01 15:35:33 +0000966- Issue #3680: Reference cycles created through a dict, set or deque iterator
967 did not get collected.
968
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000969- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
970 where the tp_hash and tp_dict slots are both NULL.
971
Georg Brandlccc47b62008-12-28 11:44:14 +0000972- Issue #4759: None is now allowed as the first argument of
973 bytearray.translate(). It was always allowed for bytes.translate().
974
Skip Montanaro80072cb2008-12-23 03:51:14 +0000975- Added test case to ensure attempts to read from a file opened for writing
976 fail.
977
Antoine Pitrou51f3ef92008-12-20 13:14:23 +0000978- Issue #3106: Speedup some comparisons (str/str and int/int).
979
Antoine Pitrouf289ae62008-12-18 11:06:25 +0000980- Issue #2183: Simplify and optimize bytecode for list, dict and set
981 comprehensions. Original patch for list comprehensions by Neal Norwitz.
982
Antoine Pitrou621601a2008-12-17 23:18:19 +0000983- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
984 print elapsed times, not only when some objects are uncollectable /
985 unreachable. Original patch by Neil Schemenauer.
986
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000987- Issue #3439: Add a bit_length method to int.
988
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000989- Issue #2173: When getting device encoding, check that return value of
990 nl_langinfo is not the empty string. This was causing silent build
991 failures on OS X.
992
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000993- Issue #4597: Fixed several opcodes that weren't always propagating
994 exceptions.
995
996- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000997 context manager returns a value that cannot be converted to a bool.
998
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000999- Issue #4445: Replace "sizeof(PyBytesObject)" with
1000 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1001 bytes instances. On a typical machine this saves 3 bytes of memory
1002 (on average) per allocation of a bytes instance.
1003
Christian Heimesa872de52008-12-05 08:26:55 +00001004- Issue #4533: File read operation was dreadfully slow due to a slowly
1005 growing read buffer. Fixed by using the same growth rate algorithm as
1006 Python 2.x.
1007
Antoine Pitrou5504e892008-12-06 21:27:53 +00001008- Issue #4509: Various issues surrounding resize of bytearray objects to
1009 which there are buffer exports (e.g. memoryview instances).
1010
Georg Brandlf9734072008-12-07 15:30:06 +00001011- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1012 method on file objects with closefd=False. The file descriptor is still
1013 kept open but the file object behaves like a closed file. The ``FileIO``
1014 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001015
Antoine Pitroubc420402008-12-07 20:14:49 +00001016- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1017 larger than 1.

1022
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001023- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1024 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1025 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1026 of using the replace error handler in PyUnicode_DecodeUTF8().

1034 opening an empty or very small file.
1035

1042 uses the same refactored function to get gcc/ld/dllwrap versions numbers.

Antoine Pitrou08838b62009-01-21 00:55:13 +00001331- Issue #5008: When a file is opened in append mode with the new IO library,
1332 do an explicit seek to the end of file (so that e.g. tell() returns the
