Benjamin Petersonbd35b032009-04-04 23:16:41 +0000626
627Core and Builtins
628-----------------
629
Mark Dickinson865e01a2009-05-07 16:37:01 +0000630- Issue #5914: Add new C API function PyOS_string_to_double, and
631 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
632
Eric Smith741191f2009-05-06 13:08:15 +0000633- Issue #3382: float.__format__, complex.__format__, and %-formatting
634 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
635 affects nan -> NAN and inf -> INF.
636
Mark Hammond5a607a32009-05-06 08:04:54 +0000637- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
638 in all operations, including splitdrive, split, etc. splitunc() now issues
639 a PendingDeprecation warning.
640
Eric Smith63376222009-05-05 14:04:18 +0000641- Issue #5920: For float.__format__, change the behavior with the
642 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
643 to be like 'g' but with at least one decimal point and with a
644 default precision of 12. Previously, the behavior the same but with
645 a default precision of 6. This more closely matches str(), and
646 reduces surprises when adding alignment flags to the empty
647 presentation type. This also affects the new complex.__format__ in
648 the same way.
649
Martin v. Löwis011e8422009-05-05 04:43:17 +0000650- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
651
R. David Murrayb18500d2009-05-04 22:59:07 +0000652- Issue #5890: in subclasses of 'property' the __doc__ attribute was
653 shadowed by classtype's, even if it was None. property now
654 inserts the __doc__ into the subclass instance __dict__.
655
Antoine Pitrou244651a2009-05-04 18:56:13 +0000656- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
657 sequences. Patch by Nick Barnes and Victor Stinner.
658
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000659- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000660
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000661- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
662 received a new method, detach(). detach() disconnects the underlying stream
663 from the buffer or text IO and returns it.
664
Mark Dickinson33841c32009-05-01 15:37:04 +0000665- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
666 floats with absolute value over 1e50. Also remove length
667 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
668 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000669
Eric Smith741191f2009-05-06 13:08:15 +0000670- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000671 format(complex(1, 2./3), '.5') now produces a sensible result.
672
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000673- Issue #5864: Fix empty format code formatting for floats so that it
674 never gives more than the requested number of significant digits.
675
Eric Smith6dc46f52009-04-27 20:39:49 +0000676- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
677 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
678
Eric Smithcc32a112009-04-26 21:35:14 +0000679- Issue #5835: Deprecate PyOS_ascii_formatd.
680
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000681- Issue #4971: Fix titlecase for characters that are their own
682 titlecase, but not their own uppercase.
683
Benjamin Peterson193152c2009-04-25 01:08:45 +0000684- Issue #5283: Setting __class__ in __del__ caused a segfault.
685
Mark Dickinsonad476da2009-04-23 19:14:16 +0000686- Issue #5816: complex(repr(z)) now recovers z exactly, even when
687 z involves nans, infs or negative zeros.
688
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000689- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000690
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000691- Issue #1869 (and many duplicates): make round(x, n) correctly
692 rounded for a float x, by using the decimal <-> binary conversions
693 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
694 consistently agrees with format(x, '.2f').
695
Benjamin Petersonae937c02009-04-18 20:54:08 +0000696- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
697 some builtin types.
698
Eric Smith0923d1d2009-04-16 20:16:10 +0000699- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
700
Eric Smith35e84722009-04-16 20:21:28 +0000701- Issue #5515: str.format() type 'n' combined with commas and leading
702 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000703
704- Implement PEP 378, Format Specifier for Thousands Separator, for
705 floats.
706
Mark Dickinson3370cce2009-04-17 22:40:53 +0000707- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000708 1e11, not 1e12. This avoids printing 13 significant digits in
709 situations where only 12 of them are correct. Example problem
710 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
711 long time.)
712
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000713- Issue #1580: On most platforms, use a 'short' float repr: for a
714 finite float x, repr(x) now outputs a string based on the shortest
715 sequence of decimal digits that rounds to x. Previous behaviour was
716 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000717 Another minor difference is that the new repr switches to
718 exponential notation at 1e16 instead of the previous 1e17; this
719 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000720
721 There's a new sys attribute sys.float_repr_style, which takes
722 the value 'short' to indicate that we're using short float repr,
723 and 'legacy' if the short float repr isn't available for one
724 reason or another.
725
726 The float repr change involves incorporating David Gay's 'perfect
727 rounding' code into the Python core (it's in Python/dtoa.c). As a
728 secondary consequence, all string-to-float and float-to-string
729 conversions (including all float formatting operations) will be
730 correctly rounded on these platforms.
731
732 See issue 1580 discussions for details of platforms for which
733 this change does not apply.
734
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000735- Issue #5759: float() didn't call __float__ on str subclasses.
736
Georg Brandlabc38772009-04-12 15:51:51 +0000737- The string.maketrans() function is deprecated; there is a new static method
738 maketrans() on the bytes and bytearray classes. This removes confusion about
739 the types string.maketrans() is supposed to work with, and mirrors the
740 methods available on the str class.
741
R. David Murraydc6da8a2009-04-09 22:16:43 +0000742- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
743 its clarity and its speed.
744
Matthias Klose091c7b12009-04-07 13:24:27 +0000745- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
746 to avoid compiler warnings.
747
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000748- Issue #3739: The unicode-internal encoder now reports the number of characters
749 consumed like any other encoder (instead of the number of bytes).

899 converted to the default filesystem encoding, causing nonsense.
900
Benjamin Peterson09832742009-03-26 17:15:46 +0000901- Issue #5126: str.isprintable() returned False for space characters.
902
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +0000903- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
904 the end sys.path, for compatibility with the system install of Python.
905
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000906- Issue #4688: Add a heuristic so that tuples and dicts containing only
907 untrackable objects are not tracked by the garbage collector. This can
908 reduce the size of collections and therefore the garbage collection overhead
909 on long-running programs, depending on their particular use of datatypes.
910
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000911- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
912 improve its performance. Long divisions and remainder operations
913 are now between 50% and 150% faster.
914
Mark Dickinsonbd792642009-03-18 20:06:12 +0000915- Issue #4258: Make it possible to use base 2**30 instead of base
916 2**15 for the internal representation of integers, for performance
917 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
918 --enable-big-digits option to configure, which overrides the
919 default. Add sys.int_info structseq to provide information about
920 the internal format.
921
Mark Dickinson081dfee2009-03-18 14:47:41 +0000922- Issue #4474: PyUnicode_FromWideChar now converts characters outside
923 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
924 and sizeof(Py_UNICODE) == 2.
925
Eric Smith8ec90442009-03-14 12:29:34 +0000926- Issue #5237: Allow auto-numbered fields in str.format(). For
927 example: '{} {}'.format(1, 2) == '1 2'.
928
Antoine Pitrou652e7072009-03-13 19:25:20 +0000929- Issue #5392: when a very low recursion limit was set, the interpreter would
930 abort with a fatal error after the recursion limit was hit twice.
931
Matthias Klose042f1332009-04-04 14:32:42 +0000932- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Mark Dickinson87ec0852009-02-09 17:15:59 +00001032- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1033 it now forces its argument to double before testing for infinity.
1034
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001035- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001044
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001045- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001046 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00001048- Issue #4707: round(x, n) now returns an integer if x is an integer.
1049 Previously it returned a float.
1050
Antoine Pitroub52ec782009-01-25 16:34:23 +00001051- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1052 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1053 evaluation loop is compiled with a new dispatch mechanism which gives
1054 speedups of up to 20%, depending on the system, on various benchmarks.
1055
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001056- Issue #4874: Most builtin decoders now reject unicode input.

1062
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001063- Issue #4838: When a module is deallocated, free the memory backing the
1064 optional module state data.
1065
Mark Dickinson8055afd2009-01-17 10:04:45 +00001066- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1067 type to (void *).
1068
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001069- Issue #4935: The overflow checking code in the expandtabs() method common
1070 to str, bytes and bytearray could be optimized away by the compiler, letting
1071 the interpreter segfault instead of raising an error.
1072
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001073- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1074 __next__ method.
1075
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001076- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1083
Antoine Pitrouab868312009-01-10 15:40:25 +00001084- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1085 common cases are optimized thanks to a dedicated fast path and a moderate
1086 amount of loop unrolling.
1087
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001088- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1089 collecting the oldest generation) so that allocating lots of objects without
1090 destroying them does not show quadratic performance. Based on a proposal by
1091 Martin von Löwis at
1092 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1093
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001094- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001095 having been closed (for instance, a read() call could return some
1096 previously buffered data). Patch by Dmitry Vasiliev.
1097
Antoine Pitrou05608432009-01-09 18:53:14 +00001098- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1099 flag to work properly. Furthermore, when specifying -u, the text stdout
1100 and stderr streams have line-by-line buffering enabled (the default being
1101 to buffer arbitrary chunks of data).
1102
Raymond Hettinger35631532009-01-09 03:58:09 +00001103- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1104 instead of ints (reducing its size from 4 to 8 times thereby reducing
1105 Python's overall memory).
1106
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001107- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1108 an existing .py counterpart, override the co_filename attributes of all
1109 code objects if the original filename is obsolete (which can happen if the
1110 file has been renamed, moved, or if it is accessed through different paths).
1111 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1112
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001113- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1114 one byte. Also fixes the meaning of len() so that it returns the number of
1115 items, rather than the size in bytes.
1116
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001117- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1118
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001119- Issue #4747: When the terminal does not use utf-8, executing a script with
1120 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1121
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001122- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001123 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001124
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001125- Issue #3680: Reference cycles created through a dict, set or deque iterator
1126 did not get collected.
1127
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001128- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1129 where the tp_hash and tp_dict slots are both NULL.
1130
Georg Brandlccc47b62008-12-28 11:44:14 +00001131- Issue #4759: None is now allowed as the first argument of
1132 bytearray.translate(). It was always allowed for bytes.translate().
1133
Skip Montanaro80072cb2008-12-23 03:51:14 +00001134- Added test case to ensure attempts to read from a file opened for writing
1135 fail.
1136
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001137- Issue #3106: Speedup some comparisons (str/str and int/int).

1140 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1141
Antoine Pitrou621601a2008-12-17 23:18:19 +00001142- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1143 print elapsed times, not only when some objects are uncollectable /
1144 unreachable. Original patch by Neil Schemenauer.
1145
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001146- Issue #3439: Add a bit_length method to int.
1147
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001148- Issue #2173: When getting device encoding, check that return value of
1149 nl_langinfo is not the empty string. This was causing silent build
1150 failures on OS X.
1151
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001152- Issue #4597: Fixed several opcodes that weren't always propagating
1153 exceptions.
1154
1155- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001156 context manager returns a value that cannot be converted to a bool.
1157
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001158- Issue #4445: Replace "sizeof(PyBytesObject)" with
1159 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1160 bytes instances. On a typical machine this saves 3 bytes of memory
1161 (on average) per allocation of a bytes instance.
1162
Christian Heimesa872de52008-12-05 08:26:55 +00001163- Issue #4533: File read operation was dreadfully slow due to a slowly
1164 growing read buffer. Fixed by using the same growth rate algorithm as
1165 Python 2.x.
1166
Antoine Pitrou5504e892008-12-06 21:27:53 +00001167- Issue #4509: Various issues surrounding resize of bytearray objects to
1168 which there are buffer exports (e.g. memoryview instances).
1169
Georg Brandlf9734072008-12-07 15:30:06 +00001170- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1171 method on file objects with closefd=False. The file descriptor is still
1172 kept open but the file object behaves like a closed file. The ``FileIO``
1173 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001174
Antoine Pitroubc420402008-12-07 20:14:49 +00001175- Issue #4569: Interpreter crash when mutating a memoryview with an item size
