Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000619*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000620
621Core and Builtins
622-----------------
623
Mark Dickinson865e01a2009-05-07 16:37:01 +0000624- Issue #5914: Add new C API function PyOS_string_to_double, and
625 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
626
Eric Smith741191f2009-05-06 13:08:15 +0000627- Issue #3382: float.__format__, complex.__format__, and %-formatting
628 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
629 affects nan -> NAN and inf -> INF.
630
Mark Hammond5a607a32009-05-06 08:04:54 +0000631- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
632 in all operations, including splitdrive, split, etc. splitunc() now issues
633 a PendingDeprecation warning.
634
Eric Smith63376222009-05-05 14:04:18 +0000635- Issue #5920: For float.__format__, change the behavior with the
636 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
637 to be like 'g' but with at least one decimal point and with a
638 default precision of 12. Previously, the behavior the same but with
639 a default precision of 6. This more closely matches str(), and
640 reduces surprises when adding alignment flags to the empty
641 presentation type. This also affects the new complex.__format__ in
642 the same way.
643
Martin v. Löwis011e8422009-05-05 04:43:17 +0000644- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
645
R. David Murrayb18500d2009-05-04 22:59:07 +0000646- Issue #5890: in subclasses of 'property' the __doc__ attribute was
647 shadowed by classtype's, even if it was None. property now
648 inserts the __doc__ into the subclass instance __dict__.
649
Antoine Pitrou244651a2009-05-04 18:56:13 +0000650- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
651 sequences. Patch by Nick Barnes and Victor Stinner.
652
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000653- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000654
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000655- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
656 received a new method, detach(). detach() disconnects the underlying stream
657 from the buffer or text IO and returns it.
658
Mark Dickinson33841c32009-05-01 15:37:04 +0000659- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
660 floats with absolute value over 1e50. Also remove length
661 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
662 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000663
Eric Smith741191f2009-05-06 13:08:15 +0000664- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000665 format(complex(1, 2./3), '.5') now produces a sensible result.
666
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000667- Issue #5864: Fix empty format code formatting for floats so that it
668 never gives more than the requested number of significant digits.
669
Eric Smith6dc46f52009-04-27 20:39:49 +0000670- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
671 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
672
Eric Smithcc32a112009-04-26 21:35:14 +0000673- Issue #5835: Deprecate PyOS_ascii_formatd.
674
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000675- Issue #4971: Fix titlecase for characters that are their own
676 titlecase, but not their own uppercase.
677
Benjamin Peterson193152c2009-04-25 01:08:45 +0000678- Issue #5283: Setting __class__ in __del__ caused a segfault.
679
Mark Dickinsonad476da2009-04-23 19:14:16 +0000680- Issue #5816: complex(repr(z)) now recovers z exactly, even when
681 z involves nans, infs or negative zeros.
682
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000683- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000684
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000685- Issue #1869 (and many duplicates): make round(x, n) correctly
686 rounded for a float x, by using the decimal <-> binary conversions
687 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
688 consistently agrees with format(x, '.2f').
689
Benjamin Petersonae937c02009-04-18 20:54:08 +0000690- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
691 some builtin types.
692
Eric Smith0923d1d2009-04-16 20:16:10 +0000693- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
694
Eric Smith35e84722009-04-16 20:21:28 +0000695- Issue #5515: str.format() type 'n' combined with commas and leading
696 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000697
698- Implement PEP 378, Format Specifier for Thousands Separator, for
699 floats.
700
Mark Dickinson3370cce2009-04-17 22:40:53 +0000701- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000702 1e11, not 1e12. This avoids printing 13 significant digits in
703 situations where only 12 of them are correct. Example problem
704 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
705 long time.)
706
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000707- Issue #1580: On most platforms, use a 'short' float repr: for a
708 finite float x, repr(x) now outputs a string based on the shortest
709 sequence of decimal digits that rounds to x. Previous behaviour was
710 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000711 Another minor difference is that the new repr switches to
712 exponential notation at 1e16 instead of the previous 1e17; this
713 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000714
715 There's a new sys attribute sys.float_repr_style, which takes
716 the value 'short' to indicate that we're using short float repr,
717 and 'legacy' if the short float repr isn't available for one
718 reason or another.
719
720 The float repr change involves incorporating David Gay's 'perfect
721 rounding' code into the Python core (it's in Python/dtoa.c). As a
722 secondary consequence, all string-to-float and float-to-string
723 conversions (including all float formatting operations) will be
724 correctly rounded on these platforms.
725
726 See issue 1580 discussions for details of platforms for which
727 this change does not apply.
728
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000729- Issue #5759: float() didn't call __float__ on str subclasses.
730
Georg Brandlabc38772009-04-12 15:51:51 +0000731- The string.maketrans() function is deprecated; there is a new static method
732 maketrans() on the bytes and bytearray classes. This removes confusion about
733 the types string.maketrans() is supposed to work with, and mirrors the
734 methods available on the str class.
735
R. David Murraydc6da8a2009-04-09 22:16:43 +0000736- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
737 its clarity and its speed.
738
Matthias Klose091c7b12009-04-07 13:24:27 +0000739- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
740 to avoid compiler warnings.
741
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000742- Issue #3739: The unicode-internal encoder now reports the number of characters
743 consumed like any other encoder (instead of the number of bytes).

898 the end sys.path, for compatibility with the system install of Python.
899
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000900- Issue #4688: Add a heuristic so that tuples and dicts containing only
901 untrackable objects are not tracked by the garbage collector. This can
902 reduce the size of collections and therefore the garbage collection overhead
903 on long-running programs, depending on their particular use of datatypes.
904
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000905- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
906 improve its performance. Long divisions and remainder operations
907 are now between 50% and 150% faster.
908
Mark Dickinsonbd792642009-03-18 20:06:12 +0000909- Issue #4258: Make it possible to use base 2**30 instead of base
910 2**15 for the internal representation of integers, for performance
911 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
912 --enable-big-digits option to configure, which overrides the
913 default. Add sys.int_info structseq to provide information about
914 the internal format.
915
Mark Dickinson081dfee2009-03-18 14:47:41 +0000916- Issue #4474: PyUnicode_FromWideChar now converts characters outside

918 and sizeof(Py_UNICODE) == 2.
919
Eric Smith8ec90442009-03-14 12:29:34 +0000920- Issue #5237: Allow auto-numbered fields in str.format(). For
921 example: '{} {}'.format(1, 2) == '1 2'.
922
Antoine Pitrou652e7072009-03-13 19:25:20 +0000923- Issue #5392: when a very low recursion limit was set, the interpreter would
924 abort with a fatal error after the recursion limit was hit twice.
925
Matthias Klose042f1332009-04-04 14:32:42 +0000926- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1015 used when using str.format() with str, int, and float arguments.
1016
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00001017- Issue #5249: time.strftime returned malformed string when format string
1018 contained non ascii character on windows.
1019
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001020- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1021 source has already been decoded into str.
1022
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001023- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1024 rotating the object pointer by 4 bits to the right.
1025
Mark Dickinson87ec0852009-02-09 17:15:59 +00001026- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1027 it now forces its argument to double before testing for infinity.
1028
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001029- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1030 returns a non-number type.
1031
Benjamin Peterson87618552009-02-08 15:00:52 +00001032- Issue #5182: Removed memoryview.__str__.

1035 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00001036 the type definition cmpfunc. The tp_compare slot has been renamed
1037 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001038
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001039- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001040 were suppressing all exceptions. These include list() and bytearray().
1041
Mark Dickinson1124e712009-01-28 21:25:58 +00001042- Issue #4707: round(x, n) now returns an integer if x is an integer.
1043 Previously it returned a float.
1044
Antoine Pitroub52ec782009-01-25 16:34:23 +00001045- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1046 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1047 evaluation loop is compiled with a new dispatch mechanism which gives
1048 speedups of up to 20%, depending on the system, on various benchmarks.
1049
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001050- Issue #4874: Most builtin decoders now reject unicode input.

1053 from a string.
1054
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001055- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1056
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001057- Issue #4838: When a module is deallocated, free the memory backing the
1058 optional module state data.
1059
Mark Dickinson8055afd2009-01-17 10:04:45 +00001060- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1061 type to (void *).
1062
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001063- Issue #4935: The overflow checking code in the expandtabs() method common
1064 to str, bytes and bytearray could be optimized away by the compiler, letting
1065 the interpreter segfault instead of raising an error.
1066
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001067- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1068 __next__ method.
1069
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001070- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1071 function no longer attempt to call the __long__ slot to convert an object
1072 to an integer. Only the __int__ and __trunc__ slots are examined.
1073
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001074- Issue #4893: Use NT threading on CE.
1075
Martin v. Löwisec59d042009-01-12 07:59:10 +00001076- Issue #4915: Port sysmodule to Windows CE.
1077
Antoine Pitrouab868312009-01-10 15:40:25 +00001078- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1079 common cases are optimized thanks to a dedicated fast path and a moderate
1080 amount of loop unrolling.
1081
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001082- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1083 collecting the oldest generation) so that allocating lots of objects without
1084 destroying them does not show quadratic performance. Based on a proposal by
1085 Martin von Löwis at
1086 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1087
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001088- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001089 having been closed (for instance, a read() call could return some
1090 previously buffered data). Patch by Dmitry Vasiliev.
1091
Antoine Pitrou05608432009-01-09 18:53:14 +00001092- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1093 flag to work properly. Furthermore, when specifying -u, the text stdout
1094 and stderr streams have line-by-line buffering enabled (the default being
1095 to buffer arbitrary chunks of data).
1096
Raymond Hettinger35631532009-01-09 03:58:09 +00001097- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1098 instead of ints (reducing its size from 4 to 8 times thereby reducing
1099 Python's overall memory).
1100
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001101- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1102 an existing .py counterpart, override the co_filename attributes of all
1103 code objects if the original filename is obsolete (which can happen if the
1104 file has been renamed, moved, or if it is accessed through different paths).
1105 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1106
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001107- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1108 one byte. Also fixes the meaning of len() so that it returns the number of
1109 items, rather than the size in bytes.
1110
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001111- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1112
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001113- Issue #4747: When the terminal does not use utf-8, executing a script with
1114 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1115
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001116- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001117 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001118
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001119- Issue #3680: Reference cycles created through a dict, set or deque iterator
1120 did not get collected.
1121
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001122- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1123 where the tp_hash and tp_dict slots are both NULL.
1124
Georg Brandlccc47b62008-12-28 11:44:14 +00001125- Issue #4759: None is now allowed as the first argument of
1126 bytearray.translate(). It was always allowed for bytes.translate().
1127
Skip Montanaro80072cb2008-12-23 03:51:14 +00001128- Added test case to ensure attempts to read from a file opened for writing
1129 fail.
1130
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001131- Issue #3106: Speedup some comparisons (str/str and int/int).

1134 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1135
Antoine Pitrou621601a2008-12-17 23:18:19 +00001136- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1137 print elapsed times, not only when some objects are uncollectable /
1138 unreachable. Original patch by Neil Schemenauer.
1139
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001140- Issue #3439: Add a bit_length method to int.
1141
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001142- Issue #2173: When getting device encoding, check that return value of
1143 nl_langinfo is not the empty string. This was causing silent build
1144 failures on OS X.
1145
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001146- Issue #4597: Fixed several opcodes that weren't always propagating
1147 exceptions.
1148
1149- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001150 context manager returns a value that cannot be converted to a bool.
1151
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001152- Issue #4445: Replace "sizeof(PyBytesObject)" with
1153 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1154 bytes instances. On a typical machine this saves 3 bytes of memory
1155 (on average) per allocation of a bytes instance.
1156
Christian Heimesa872de52008-12-05 08:26:55 +00001157- Issue #4533: File read operation was dreadfully slow due to a slowly
1158 growing read buffer. Fixed by using the same growth rate algorithm as
1159 Python 2.x.
1160
Antoine Pitrou5504e892008-12-06 21:27:53 +00001161- Issue #4509: Various issues surrounding resize of bytearray objects to
1162 which there are buffer exports (e.g. memoryview instances).
1163
Georg Brandlf9734072008-12-07 15:30:06 +00001164- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1165 method on file objects with closefd=False. The file descriptor is still
1166 kept open but the file object behaves like a closed file. The ``FileIO``
1167 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001168
Antoine Pitroubc420402008-12-07 20:14:49 +00001169- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1170 larger than 1.
1171

1175
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001176- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1177 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1178 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1179 of using the replace error handler in PyUnicode_DecodeUTF8().
