Benjamin Petersonbd35b032009-04-04 23:16:41 +0000636
637Core and Builtins
638-----------------
639
Mark Dickinson865e01a2009-05-07 16:37:01 +0000640- Issue #5914: Add new C API function PyOS_string_to_double, and
641 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
642
Eric Smith741191f2009-05-06 13:08:15 +0000643- Issue #3382: float.__format__, complex.__format__, and %-formatting
644 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
645 affects nan -> NAN and inf -> INF.
646
Mark Hammond5a607a32009-05-06 08:04:54 +0000647- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
648 in all operations, including splitdrive, split, etc. splitunc() now issues
649 a PendingDeprecation warning.
650
Eric Smith63376222009-05-05 14:04:18 +0000651- Issue #5920: For float.__format__, change the behavior with the
652 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
653 to be like 'g' but with at least one decimal point and with a
654 default precision of 12. Previously, the behavior the same but with
655 a default precision of 6. This more closely matches str(), and
656 reduces surprises when adding alignment flags to the empty
657 presentation type. This also affects the new complex.__format__ in
658 the same way.
659
Martin v. Löwis011e8422009-05-05 04:43:17 +0000660- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
661
R. David Murrayb18500d2009-05-04 22:59:07 +0000662- Issue #5890: in subclasses of 'property' the __doc__ attribute was
663 shadowed by classtype's, even if it was None. property now
664 inserts the __doc__ into the subclass instance __dict__.
665
Antoine Pitrou244651a2009-05-04 18:56:13 +0000666- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
667 sequences. Patch by Nick Barnes and Victor Stinner.
668
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000669- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000670
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000671- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
672 received a new method, detach(). detach() disconnects the underlying stream
673 from the buffer or text IO and returns it.
674
Mark Dickinson33841c32009-05-01 15:37:04 +0000675- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
676 floats with absolute value over 1e50. Also remove length
677 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
678 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000679
Eric Smith741191f2009-05-06 13:08:15 +0000680- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000681 format(complex(1, 2./3), '.5') now produces a sensible result.
682
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000683- Issue #5864: Fix empty format code formatting for floats so that it
684 never gives more than the requested number of significant digits.
685
Eric Smith6dc46f52009-04-27 20:39:49 +0000686- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
687 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
688
Eric Smithcc32a112009-04-26 21:35:14 +0000689- Issue #5835: Deprecate PyOS_ascii_formatd.
690
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000691- Issue #4971: Fix titlecase for characters that are their own
692 titlecase, but not their own uppercase.
693
Benjamin Peterson193152c2009-04-25 01:08:45 +0000694- Issue #5283: Setting __class__ in __del__ caused a segfault.
695
Mark Dickinsonad476da2009-04-23 19:14:16 +0000696- Issue #5816: complex(repr(z)) now recovers z exactly, even when
697 z involves nans, infs or negative zeros.
698
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000699- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000700
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000701- Issue #1869 (and many duplicates): make round(x, n) correctly
702 rounded for a float x, by using the decimal <-> binary conversions
703 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
704 consistently agrees with format(x, '.2f').
705
Benjamin Petersonae937c02009-04-18 20:54:08 +0000706- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
707 some builtin types.
708
Eric Smith0923d1d2009-04-16 20:16:10 +0000709- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
710
Eric Smith35e84722009-04-16 20:21:28 +0000711- Issue #5515: str.format() type 'n' combined with commas and leading
712 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000713
714- Implement PEP 378, Format Specifier for Thousands Separator, for
715 floats.
716
Mark Dickinson3370cce2009-04-17 22:40:53 +0000717- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000718 1e11, not 1e12. This avoids printing 13 significant digits in
719 situations where only 12 of them are correct. Example problem
720 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
721 long time.)
722
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000723- Issue #1580: On most platforms, use a 'short' float repr: for a
724 finite float x, repr(x) now outputs a string based on the shortest
725 sequence of decimal digits that rounds to x. Previous behaviour was
726 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000727 Another minor difference is that the new repr switches to
728 exponential notation at 1e16 instead of the previous 1e17; this
729 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000730
731 There's a new sys attribute sys.float_repr_style, which takes
732 the value 'short' to indicate that we're using short float repr,
733 and 'legacy' if the short float repr isn't available for one
734 reason or another.
735
736 The float repr change involves incorporating David Gay's 'perfect
737 rounding' code into the Python core (it's in Python/dtoa.c). As a
738 secondary consequence, all string-to-float and float-to-string
739 conversions (including all float formatting operations) will be
740 correctly rounded on these platforms.
741
742 See issue 1580 discussions for details of platforms for which
743 this change does not apply.
744
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000745- Issue #5759: float() didn't call __float__ on str subclasses.
746
Georg Brandlabc38772009-04-12 15:51:51 +0000747- The string.maketrans() function is deprecated; there is a new static method
748 maketrans() on the bytes and bytearray classes. This removes confusion about
749 the types string.maketrans() is supposed to work with, and mirrors the
750 methods available on the str class.
751
R. David Murraydc6da8a2009-04-09 22:16:43 +0000752- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
753 its clarity and its speed.
754
Matthias Klose091c7b12009-04-07 13:24:27 +0000755- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
756 to avoid compiler warnings.
757
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000758- Issue #3739: The unicode-internal encoder now reports the number of characters
759 consumed like any other encoder (instead of the number of bytes).

Mark Dickinsonbd792642009-03-18 20:06:12 +0000925- Issue #4258: Make it possible to use base 2**30 instead of base
926 2**15 for the internal representation of integers, for performance
927 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
928 --enable-big-digits option to configure, which overrides the
929 default. Add sys.int_info structseq to provide information about
930 the internal format.

1031 used when using str.format() with str, int, and float arguments.
1032
Hirokazu Yamamoto575d1332009-02-16 09:13:20 +00001033- Issue #5249: time.strftime returned malformed string when format string
1034 contained non ascii character on windows.
1035
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001036- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1037 source has already been decoded into str.
1038

1040 rotating the object pointer by 4 bits to the right.
1041
Mark Dickinson87ec0852009-02-09 17:15:59 +00001042- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1043 it now forces its argument to double before testing for infinity.
1044
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001045- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1046 returns a non-number type.
1047
Benjamin Peterson87618552009-02-08 15:00:52 +00001048- Issue #5182: Removed memoryview.__str__.

1053 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001054
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001055- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001056 were suppressing all exceptions. These include list() and bytearray().
1057
Mark Dickinson1124e712009-01-28 21:25:58 +00001058- Issue #4707: round(x, n) now returns an integer if x is an integer.
1059 Previously it returned a float.
1060
Antoine Pitroub52ec782009-01-25 16:34:23 +00001061- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1062 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1063 evaluation loop is compiled with a new dispatch mechanism which gives
1064 speedups of up to 20%, depending on the system, on various benchmarks.
1065
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001066- Issue #4874: Most builtin decoders now reject unicode input.

1072
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001073- Issue #4838: When a module is deallocated, free the memory backing the
1074 optional module state data.
1075
Mark Dickinson8055afd2009-01-17 10:04:45 +00001076- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1077 type to (void *).
1078
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001079- Issue #4935: The overflow checking code in the expandtabs() method common
1080 to str, bytes and bytearray could be optimized away by the compiler, letting
1081 the interpreter segfault instead of raising an error.
1082
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001083- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1084 __next__ method.
1085
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001086- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1087 function no longer attempt to call the __long__ slot to convert an object
1088 to an integer. Only the __int__ and __trunc__ slots are examined.
1089
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001090- Issue #4893: Use NT threading on CE.
1091
Martin v. Löwisec59d042009-01-12 07:59:10 +00001092- Issue #4915: Port sysmodule to Windows CE.
1093
Antoine Pitrouab868312009-01-10 15:40:25 +00001094- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1095 common cases are optimized thanks to a dedicated fast path and a moderate
1096 amount of loop unrolling.
1097
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001098- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1099 collecting the oldest generation) so that allocating lots of objects without
1100 destroying them does not show quadratic performance. Based on a proposal by
1101 Martin von Löwis at
1102 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1103
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001104- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001105 having been closed (for instance, a read() call could return some
1106 previously buffered data). Patch by Dmitry Vasiliev.
1107
Antoine Pitrou05608432009-01-09 18:53:14 +00001108- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1109 flag to work properly. Furthermore, when specifying -u, the text stdout
1110 and stderr streams have line-by-line buffering enabled (the default being
1111 to buffer arbitrary chunks of data).
1112
Raymond Hettinger35631532009-01-09 03:58:09 +00001113- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1114 instead of ints (reducing its size from 4 to 8 times thereby reducing
1115 Python's overall memory).
1116
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001117- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1118 an existing .py counterpart, override the co_filename attributes of all
1119 code objects if the original filename is obsolete (which can happen if the
1120 file has been renamed, moved, or if it is accessed through different paths).
1121 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1122
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001123- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1124 one byte. Also fixes the meaning of len() so that it returns the number of
1125 items, rather than the size in bytes.
1126
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001127- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1128
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001129- Issue #4747: When the terminal does not use utf-8, executing a script with
1130 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1131
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001132- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001133 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001134
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001135- Issue #3680: Reference cycles created through a dict, set or deque iterator
1136 did not get collected.
1137
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001138- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1139 where the tp_hash and tp_dict slots are both NULL.
1140
Georg Brandlccc47b62008-12-28 11:44:14 +00001141- Issue #4759: None is now allowed as the first argument of
1142 bytearray.translate(). It was always allowed for bytes.translate().
1143
Skip Montanaro80072cb2008-12-23 03:51:14 +00001144- Added test case to ensure attempts to read from a file opened for writing
1145 fail.
1146
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001147- Issue #3106: Speedup some comparisons (str/str and int/int).

1151
Antoine Pitrou621601a2008-12-17 23:18:19 +00001152- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1153 print elapsed times, not only when some objects are uncollectable /
1154 unreachable. Original patch by Neil Schemenauer.
1155
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001156- Issue #3439: Add a bit_length method to int.
1157
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001158- Issue #2173: When getting device encoding, check that return value of
1159 nl_langinfo is not the empty string. This was causing silent build
1160 failures on OS X.
1161
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001162- Issue #4597: Fixed several opcodes that weren't always propagating
1163 exceptions.
1164
1165- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001166 context manager returns a value that cannot be converted to a bool.
1167
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001168- Issue #4445: Replace "sizeof(PyBytesObject)" with
1169 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1170 bytes instances. On a typical machine this saves 3 bytes of memory
1171 (on average) per allocation of a bytes instance.
1172
Christian Heimesa872de52008-12-05 08:26:55 +00001173- Issue #4533: File read operation was dreadfully slow due to a slowly
1174 growing read buffer. Fixed by using the same growth rate algorithm as
1175 Python 2.x.
1176
Antoine Pitrou5504e892008-12-06 21:27:53 +00001177- Issue #4509: Various issues surrounding resize of bytearray objects to
1178 which there are buffer exports (e.g. memoryview instances).
1179
Georg Brandlf9734072008-12-07 15:30:06 +00001180- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1181 method on file objects with closefd=False. The file descriptor is still
1182 kept open but the file object behaves like a closed file. The ``FileIO``
1183 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001192- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1193 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1194 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1195 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00001800- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
1801 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1802 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1803 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00001805- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00001806 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00001807 from test support, which does the conversion.
