321
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000322- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
323 of the command line.
324

328 that would raise SystemError.
329
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000330- Issue #5982: staticmethod and classmethod now expose the wrapped
331 function with __func__.
332
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000333- Added support for multiple context managers in the same with-statement.
334 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000336- Issue #5829: complex("1e500") no longer raises OverflowError. This
337 makes it consistent with float("1e500") and interpretation of real
338 and imaginary literals.
339
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000340- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

343
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000344- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
345 (1) inf and nan strings with trailing whitespace were incorrectly
346 rejected; (2) parsing of strings representing infinities and nans
347 was locale aware; and (3) the interpretation of fromhex('-nan')
348 didn't match that of float('-nan').

Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000363- collections.namedtuple() was not working with the following field
364 names: cls, self, tuple, itemgetter, and property.
365
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000366- In unittest, using a skipping decorator on a class is now equivalent to
367 skipping every test on the class. The ClassTestSuite class has been removed.
368
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000369- Issue #6050: Don't fail extracting a directory from a zipfile if
370 the directory already exists.
371
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000372- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
373 than an int, which makes some operations possible under 64-bit Linux (e.g.
374 DN_MULTISHOT with F_NOTIFY).
375
Antoine Pitrou716c4442009-05-23 19:04:03 +0000376- Issue #5761: Add the name of the underlying file to the repr() of various

Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000382- Issue #1983: Fix functions taking or returning a process identifier to use
383 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
384 a process identifier type wider than the standard C integer type.
385
R. David Murray87e20742009-05-23 01:30:26 +0000386- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

397
Antoine Pitroue4501852009-05-14 18:55:55 +0000398- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
399 library. This means, for example, that opening an UTF-16 text file in
400 append mode doesn't add a BOM at the end of the file if the file isn't
401 empty.
402
R. David Murray74b89242009-05-13 17:33:03 +0000403- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
404 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
405 corrects a pydoc regression.
406

451Core and Builtins
452-----------------
453
Mark Dickinson865e01a2009-05-07 16:37:01 +0000454- Issue #5914: Add new C API function PyOS_string_to_double, and
455 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
456
Eric Smith741191f2009-05-06 13:08:15 +0000457- Issue #3382: float.__format__, complex.__format__, and %-formatting
458 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
459 affects nan -> NAN and inf -> INF.
460
Mark Hammond5a607a32009-05-06 08:04:54 +0000461- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
462 in all operations, including splitdrive, split, etc. splitunc() now issues
463 a PendingDeprecation warning.
464
Eric Smith63376222009-05-05 14:04:18 +0000465- Issue #5920: For float.__format__, change the behavior with the
466 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
467 to be like 'g' but with at least one decimal point and with a
468 default precision of 12. Previously, the behavior the same but with
469 a default precision of 6. This more closely matches str(), and
470 reduces surprises when adding alignment flags to the empty
471 presentation type. This also affects the new complex.__format__ in
472 the same way.
473
Martin v. Löwis011e8422009-05-05 04:43:17 +0000474- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
475
R. David Murrayb18500d2009-05-04 22:59:07 +0000476- Issue #5890: in subclasses of 'property' the __doc__ attribute was
477 shadowed by classtype's, even if it was None. property now
478 inserts the __doc__ into the subclass instance __dict__.
479
Antoine Pitrou244651a2009-05-04 18:56:13 +0000480- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
481 sequences. Patch by Nick Barnes and Victor Stinner.
482
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000483- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000484
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000485- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
486 received a new method, detach(). detach() disconnects the underlying stream
487 from the buffer or text IO and returns it.
488
Mark Dickinson33841c32009-05-01 15:37:04 +0000489- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
490 floats with absolute value over 1e50. Also remove length
491 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
492 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000493
Eric Smith741191f2009-05-06 13:08:15 +0000494- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000495 format(complex(1, 2./3), '.5') now produces a sensible result.
496
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000497- Issue #5864: Fix empty format code formatting for floats so that it
498 never gives more than the requested number of significant digits.
499
Eric Smith6dc46f52009-04-27 20:39:49 +0000500- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
501 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
502
Eric Smithcc32a112009-04-26 21:35:14 +0000503- Issue #5835: Deprecate PyOS_ascii_formatd.
504
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000505- Issue #4971: Fix titlecase for characters that are their own
506 titlecase, but not their own uppercase.
507
Benjamin Peterson193152c2009-04-25 01:08:45 +0000508- Issue #5283: Setting __class__ in __del__ caused a segfault.
509
Mark Dickinsonad476da2009-04-23 19:14:16 +0000510- Issue #5816: complex(repr(z)) now recovers z exactly, even when
511 z involves nans, infs or negative zeros.
512
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000513- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000514
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000515- Issue #1869 (and many duplicates): make round(x, n) correctly
516 rounded for a float x, by using the decimal <-> binary conversions
517 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
518 consistently agrees with format(x, '.2f').
519
Benjamin Petersonae937c02009-04-18 20:54:08 +0000520- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
521 some builtin types.
522
Eric Smith0923d1d2009-04-16 20:16:10 +0000523- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
524
Eric Smith35e84722009-04-16 20:21:28 +0000525- Issue #5515: str.format() type 'n' combined with commas and leading
526 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000527
528- Implement PEP 378, Format Specifier for Thousands Separator, for
529 floats.
530
Mark Dickinson3370cce2009-04-17 22:40:53 +0000531- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000532 1e11, not 1e12. This avoids printing 13 significant digits in
533 situations where only 12 of them are correct. Example problem
534 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
535 long time.)
536
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000537- Issue #1580: On most platforms, use a 'short' float repr: for a
538 finite float x, repr(x) now outputs a string based on the shortest
539 sequence of decimal digits that rounds to x. Previous behaviour was
540 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000541 Another minor difference is that the new repr switches to
542 exponential notation at 1e16 instead of the previous 1e17; this
543 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000544
545 There's a new sys attribute sys.float_repr_style, which takes
546 the value 'short' to indicate that we're using short float repr,
547 and 'legacy' if the short float repr isn't available for one
548 reason or another.
549
550 The float repr change involves incorporating David Gay's 'perfect
551 rounding' code into the Python core (it's in Python/dtoa.c). As a
552 secondary consequence, all string-to-float and float-to-string
553 conversions (including all float formatting operations) will be
554 correctly rounded on these platforms.
555
556 See issue 1580 discussions for details of platforms for which
557 this change does not apply.
558
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000559- Issue #5759: float() didn't call __float__ on str subclasses.
560
Georg Brandlabc38772009-04-12 15:51:51 +0000561- The string.maketrans() function is deprecated; there is a new static method
562 maketrans() on the bytes and bytearray classes. This removes confusion about
563 the types string.maketrans() is supposed to work with, and mirrors the
564 methods available on the str class.
565
R. David Murraydc6da8a2009-04-09 22:16:43 +0000566- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
567 its clarity and its speed.
568
Matthias Klose091c7b12009-04-07 13:24:27 +0000569- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
570 to avoid compiler warnings.
571
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000572- Issue #3739: The unicode-internal encoder now reports the number of characters
573 consumed like any other encoder (instead of the number of bytes).

585
Raymond Hettingereb816952009-05-29 01:22:18 +0000586- Issue #5150: IDLE's format menu now has an option to strip trailing

588
Vinay Sajipaffbd872009-06-11 10:11:47 +0000589- Issue #5940: distutils.command.build_clib.check_library_list was not doing

Mark Dickinsone5e298f2009-01-12 20:49:19 +0000900- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
901 function no longer attempt to call the __long__ slot to convert an object
902 to an integer. Only the __int__ and __trunc__ slots are examined.

907
Antoine Pitrouab868312009-01-10 15:40:25 +0000908- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
909 common cases are optimized thanks to a dedicated fast path and a moderate
910 amount of loop unrolling.
911
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000912- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
913 collecting the oldest generation) so that allocating lots of objects without
914 destroying them does not show quadratic performance. Based on a proposal by
915 Martin von Löwis at
916 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
917
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000918- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000919 having been closed (for instance, a read() call could return some
920 previously buffered data). Patch by Dmitry Vasiliev.
921
Antoine Pitrou05608432009-01-09 18:53:14 +0000922- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
923 flag to work properly. Furthermore, when specifying -u, the text stdout
924 and stderr streams have line-by-line buffering enabled (the default being
925 to buffer arbitrary chunks of data).
926
Raymond Hettinger35631532009-01-09 03:58:09 +0000927- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
928 instead of ints (reducing its size from 4 to 8 times thereby reducing
929 Python's overall memory).
930
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000931- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
932 an existing .py counterpart, override the co_filename attributes of all
933 code objects if the original filename is obsolete (which can happen if the
934 file has been renamed, moved, or if it is accessed through different paths).
935 Patch by Ziga Seilnacht and Jean-Paul Calderone.
936
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000937- Issue #4580: Fix slicing of memoryviews when the item size is greater than
938 one byte. Also fixes the meaning of len() so that it returns the number of
939 items, rather than the size in bytes.
940
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000941- Issue #4075: Use OutputDebugStringW in Py_FatalError.

951
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000952- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
953 where the tp_hash and tp_dict slots are both NULL.
954
Georg Brandlccc47b62008-12-28 11:44:14 +0000955- Issue #4759: None is now allowed as the first argument of
956 bytearray.translate(). It was always allowed for bytes.translate().
957
Skip Montanaro80072cb2008-12-23 03:51:14 +0000958- Added test case to ensure attempts to read from a file opened for writing
959 fail.

965
Antoine Pitrou621601a2008-12-17 23:18:19 +0000966- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

968 unreachable. Original patch by Neil Schemenauer.
969

974 failures on OS X.
975
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000976- Issue #4597: Fixed several opcodes that weren't always propagating
977 exceptions.
978
979- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000980 context manager returns a value that cannot be converted to a bool.
981
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000982- Issue #4445: Replace "sizeof(PyBytesObject)" with
983 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
984 bytes instances. On a typical machine this saves 3 bytes of memory
985 (on average) per allocation of a bytes instance.
986
Christian Heimesa872de52008-12-05 08:26:55 +0000987- Issue #4533: File read operation was dreadfully slow due to a slowly
988 growing read buffer. Fixed by using the same growth rate algorithm as
989 Python 2.x.
990
Antoine Pitrou5504e892008-12-06 21:27:53 +0000991- Issue #4509: Various issues surrounding resize of bytearray objects to
992 which there are buffer exports (e.g. memoryview instances).
993
Georg Brandlf9734072008-12-07 15:30:06 +0000994- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
995 method on file objects with closefd=False. The file descriptor is still
996 kept open but the file object behaves like a closed file. The ``FileIO``
997 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000998
Antoine Pitroubc420402008-12-07 20:14:49 +0000999- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001006- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1007 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1008 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1009 of using the replace error handler in PyUnicode_DecodeUTF8().

1286
Antoine Pitrou08838b62009-01-21 00:55:13 +00001287- Issue #5008: When a file is opened in append mode with the new IO library,
1288 do an explicit seek to the end of file (so that e.g. tell() returns the
1289 file size rather than 0). This is consistent with the behaviour of the

1320 appropriately when it is being used via socket.makefile() objects
1321 rather than delaying the close by waiting for garbage collection to do it.
