Benjamin Peterson0926ad12009-06-06 18:02:12 +0000324- Issue #6217: The C implementation of io.TextIOWrapper didn't include the
325 errors property. Additionally, the errors and encoding properties of StringIO
326 are always None now.
327
Antoine Pitroud9dfaa92009-06-04 20:32:06 +0000328- Issue #6137: The pickle module now translates module names when loading
329 or dumping pickles with a 2.x-compatible protocol, in order to make data
330 sharing and migration easier. This behaviour can be disabled using the
331 new `fix_imports` optional argument.

386 that would raise SystemError.
387
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000388- Issue #5982: staticmethod and classmethod now expose the wrapped
389 function with __func__.
390
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000391- Added support for multiple context managers in the same with-statement.
392 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000394- Issue #5829: complex("1e500") no longer raises OverflowError. This
395 makes it consistent with float("1e500") and interpretation of real
396 and imaginary literals.
397
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000398- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

401
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000402- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
403 (1) inf and nan strings with trailing whitespace were incorrectly
404 rejected; (2) parsing of strings representing infinities and nans
405 was locale aware; and (3) the interpretation of fromhex('-nan')
406 didn't match that of float('-nan').

Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000421- collections.namedtuple() was not working with the following field
422 names: cls, self, tuple, itemgetter, and property.
423
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000424- In unittest, using a skipping decorator on a class is now equivalent to
425 skipping every test on the class. The ClassTestSuite class has been removed.
426
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000427- Issue #6050: Don't fail extracting a directory from a zipfile if
428 the directory already exists.
429
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000430- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
431 than an int, which makes some operations possible under 64-bit Linux (e.g.
432 DN_MULTISHOT with F_NOTIFY).
433
Antoine Pitrou716c4442009-05-23 19:04:03 +0000434- Issue #5761: Add the name of the underlying file to the repr() of various

438 by Musashi Tamura, tests by Marcin Bachry.
439
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000440- Issue #1983: Fix functions taking or returning a process identifier to use
441 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
442 a process identifier type wider than the standard C integer type.
443
R. David Murray87e20742009-05-23 01:30:26 +0000444- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
445 Patch by Farhan Ahmad, test by Marcin Bachry.

455
Antoine Pitroue4501852009-05-14 18:55:55 +0000456- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
457 library. This means, for example, that opening an UTF-16 text file in
458 append mode doesn't add a BOM at the end of the file if the file isn't
459 empty.
460
R. David Murray74b89242009-05-13 17:33:03 +0000461- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
462 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
463 corrects a pydoc regression.
464
R. David Murray99352742009-05-07 18:24:38 +0000465- Issue 5955: aifc's close method did not close the file it wrapped,
466 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000508
509Core and Builtins
510-----------------
511
Mark Dickinson865e01a2009-05-07 16:37:01 +0000512- Issue #5914: Add new C API function PyOS_string_to_double, and
513 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
514
Eric Smith741191f2009-05-06 13:08:15 +0000515- Issue #3382: float.__format__, complex.__format__, and %-formatting
516 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
517 affects nan -> NAN and inf -> INF.
518
Mark Hammond5a607a32009-05-06 08:04:54 +0000519- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
520 in all operations, including splitdrive, split, etc. splitunc() now issues
521 a PendingDeprecation warning.
522
Eric Smith63376222009-05-05 14:04:18 +0000523- Issue #5920: For float.__format__, change the behavior with the
524 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
525 to be like 'g' but with at least one decimal point and with a
526 default precision of 12. Previously, the behavior the same but with
527 a default precision of 6. This more closely matches str(), and
528 reduces surprises when adding alignment flags to the empty
529 presentation type. This also affects the new complex.__format__ in
530 the same way.
531
Martin v. Löwis011e8422009-05-05 04:43:17 +0000532- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
533
R. David Murrayb18500d2009-05-04 22:59:07 +0000534- Issue #5890: in subclasses of 'property' the __doc__ attribute was
535 shadowed by classtype's, even if it was None. property now
536 inserts the __doc__ into the subclass instance __dict__.
537
Antoine Pitrou244651a2009-05-04 18:56:13 +0000538- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
539 sequences. Patch by Nick Barnes and Victor Stinner.
540
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000541- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000542
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000543- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
544 received a new method, detach(). detach() disconnects the underlying stream
545 from the buffer or text IO and returns it.
546
Mark Dickinson33841c32009-05-01 15:37:04 +0000547- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
548 floats with absolute value over 1e50. Also remove length
549 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
550 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000551
Eric Smith741191f2009-05-06 13:08:15 +0000552- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000553 format(complex(1, 2./3), '.5') now produces a sensible result.
554
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000555- Issue #5864: Fix empty format code formatting for floats so that it
556 never gives more than the requested number of significant digits.
557
Eric Smith6dc46f52009-04-27 20:39:49 +0000558- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
559 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
560
Eric Smithcc32a112009-04-26 21:35:14 +0000561- Issue #5835: Deprecate PyOS_ascii_formatd.
562
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000563- Issue #4971: Fix titlecase for characters that are their own
564 titlecase, but not their own uppercase.
565
Benjamin Peterson193152c2009-04-25 01:08:45 +0000566- Issue #5283: Setting __class__ in __del__ caused a segfault.
567
Mark Dickinsonad476da2009-04-23 19:14:16 +0000568- Issue #5816: complex(repr(z)) now recovers z exactly, even when
569 z involves nans, infs or negative zeros.
570
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000571- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000572
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000573- Issue #1869 (and many duplicates): make round(x, n) correctly
574 rounded for a float x, by using the decimal <-> binary conversions
575 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
576 consistently agrees with format(x, '.2f').
577
Benjamin Petersonae937c02009-04-18 20:54:08 +0000578- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
579 some builtin types.
580
Eric Smith0923d1d2009-04-16 20:16:10 +0000581- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
582
Eric Smith35e84722009-04-16 20:21:28 +0000583- Issue #5515: str.format() type 'n' combined with commas and leading
584 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000585
586- Implement PEP 378, Format Specifier for Thousands Separator, for
587 floats.
588
Mark Dickinson3370cce2009-04-17 22:40:53 +0000589- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000590 1e11, not 1e12. This avoids printing 13 significant digits in
591 situations where only 12 of them are correct. Example problem
592 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
593 long time.)
594
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000595- Issue #1580: On most platforms, use a 'short' float repr: for a
596 finite float x, repr(x) now outputs a string based on the shortest
597 sequence of decimal digits that rounds to x. Previous behaviour was
598 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000599 Another minor difference is that the new repr switches to
600 exponential notation at 1e16 instead of the previous 1e17; this
601 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000602
603 There's a new sys attribute sys.float_repr_style, which takes
604 the value 'short' to indicate that we're using short float repr,
605 and 'legacy' if the short float repr isn't available for one
606 reason or another.
607
608 The float repr change involves incorporating David Gay's 'perfect
609 rounding' code into the Python core (it's in Python/dtoa.c). As a
610 secondary consequence, all string-to-float and float-to-string
611 conversions (including all float formatting operations) will be
612 correctly rounded on these platforms.
613
614 See issue 1580 discussions for details of platforms for which
615 this change does not apply.
616
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000617- Issue #5759: float() didn't call __float__ on str subclasses.
618
Georg Brandlabc38772009-04-12 15:51:51 +0000619- The string.maketrans() function is deprecated; there is a new static method
620 maketrans() on the bytes and bytearray classes. This removes confusion about
621 the types string.maketrans() is supposed to work with, and mirrors the
622 methods available on the str class.

Georg Brandl1cdd83c2009-04-05 20:24:29 +0000927- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000928 were suppressing all exceptions. These include list() and bytearray().
929
Mark Dickinson1124e712009-01-28 21:25:58 +0000930- Issue #4707: round(x, n) now returns an integer if x is an integer.
931 Previously it returned a float.
932
Antoine Pitroub52ec782009-01-25 16:34:23 +0000933- Issue #4753: By enabling a configure option named '--with-computed-gotos'
934 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
935 evaluation loop is compiled with a new dispatch mechanism which gives
936 speedups of up to 20%, depending on the system, on various benchmarks.

947
Mark Dickinson8055afd2009-01-17 10:04:45 +0000948- Issue #4910: Rename nb_long slot to nb_reserved, and change its
949 type to (void *).
950
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000951- Issue #4935: The overflow checking code in the expandtabs() method common
952 to str, bytes and bytearray could be optimized away by the compiler, letting
953 the interpreter segfault instead of raising an error.
954
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000955- Issue #3720: Fix a crash when an iterator modifies its class and removes its
956 __next__ method.
957
Mark Dickinsone5e298f2009-01-12 20:49:19 +0000958- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
959 function no longer attempt to call the __long__ slot to convert an object
960 to an integer. Only the __int__ and __trunc__ slots are examined.

965
Antoine Pitrouab868312009-01-10 15:40:25 +0000966- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
967 common cases are optimized thanks to a dedicated fast path and a moderate
968 amount of loop unrolling.
969
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000970- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
971 collecting the oldest generation) so that allocating lots of objects without
972 destroying them does not show quadratic performance. Based on a proposal by
973 Martin von Löwis at
974 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
975
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000976- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000977 having been closed (for instance, a read() call could return some
978 previously buffered data). Patch by Dmitry Vasiliev.
979
Antoine Pitrou05608432009-01-09 18:53:14 +0000980- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
981 flag to work properly. Furthermore, when specifying -u, the text stdout
982 and stderr streams have line-by-line buffering enabled (the default being
983 to buffer arbitrary chunks of data).
984
Raymond Hettinger35631532009-01-09 03:58:09 +0000985- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
986 instead of ints (reducing its size from 4 to 8 times thereby reducing
987 Python's overall memory).
988
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000989- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
990 an existing .py counterpart, override the co_filename attributes of all
991 code objects if the original filename is obsolete (which can happen if the
992 file has been renamed, moved, or if it is accessed through different paths).
993 Patch by Ziga Seilnacht and Jean-Paul Calderone.
994
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000995- Issue #4580: Fix slicing of memoryviews when the item size is greater than
996 one byte. Also fixes the meaning of len() so that it returns the number of
997 items, rather than the size in bytes.
998
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000999- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001001- Issue #4747: When the terminal does not use utf-8, executing a script with
1002 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1003
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001004- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1008 did not get collected.
1009
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001010- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1011 where the tp_hash and tp_dict slots are both NULL.
1012
Georg Brandlccc47b62008-12-28 11:44:14 +00001013- Issue #4759: None is now allowed as the first argument of
1014 bytearray.translate(). It was always allowed for bytes.translate().
1015
Skip Montanaro80072cb2008-12-23 03:51:14 +00001016- Added test case to ensure attempts to read from a file opened for writing
1017 fail.

1023
Antoine Pitrou621601a2008-12-17 23:18:19 +00001024- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00001030- Issue #2173: When getting device encoding, check that return value of
1031 nl_langinfo is not the empty string. This was causing silent build
1032 failures on OS X.
1033
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001034- Issue #4597: Fixed several opcodes that weren't always propagating
1035 exceptions.
1036
1037- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001038 context manager returns a value that cannot be converted to a bool.
1039
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001040- Issue #4445: Replace "sizeof(PyBytesObject)" with
1041 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1042 bytes instances. On a typical machine this saves 3 bytes of memory
1043 (on average) per allocation of a bytes instance.
1044
Christian Heimesa872de52008-12-05 08:26:55 +00001045- Issue #4533: File read operation was dreadfully slow due to a slowly
1046 growing read buffer. Fixed by using the same growth rate algorithm as
1047 Python 2.x.
1048
Antoine Pitrou5504e892008-12-06 21:27:53 +00001049- Issue #4509: Various issues surrounding resize of bytearray objects to
1050 which there are buffer exports (e.g. memoryview instances).
1051
Georg Brandlf9734072008-12-07 15:30:06 +00001052- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1053 method on file objects with closefd=False. The file descriptor is still
1054 kept open but the file object behaves like a closed file. The ``FileIO``
1055 object also got a new readonly attribute ``closefd``.

1063
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001064- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1065 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1066 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1067 of using the replace error handler in PyUnicode_DecodeUTF8().

1486 Alexander Belopolsky.
1487
