614Core and Builtins
615-----------------
616
Mark Dickinson865e01a2009-05-07 16:37:01 +0000617- Issue #5914: Add new C API function PyOS_string_to_double, and
618 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
619
Eric Smith741191f2009-05-06 13:08:15 +0000620- Issue #3382: float.__format__, complex.__format__, and %-formatting
621 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
622 affects nan -> NAN and inf -> INF.
623
Mark Hammond5a607a32009-05-06 08:04:54 +0000624- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
625 in all operations, including splitdrive, split, etc. splitunc() now issues
626 a PendingDeprecation warning.
627
Eric Smith63376222009-05-05 14:04:18 +0000628- Issue #5920: For float.__format__, change the behavior with the
629 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
630 to be like 'g' but with at least one decimal point and with a
631 default precision of 12. Previously, the behavior the same but with
632 a default precision of 6. This more closely matches str(), and
633 reduces surprises when adding alignment flags to the empty
634 presentation type. This also affects the new complex.__format__ in
635 the same way.
636
Martin v. Löwis011e8422009-05-05 04:43:17 +0000637- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
638
R. David Murrayb18500d2009-05-04 22:59:07 +0000639- Issue #5890: in subclasses of 'property' the __doc__ attribute was
640 shadowed by classtype's, even if it was None. property now
641 inserts the __doc__ into the subclass instance __dict__.
642
Antoine Pitrou244651a2009-05-04 18:56:13 +0000643- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
644 sequences. Patch by Nick Barnes and Victor Stinner.
645
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000646- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000647
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000648- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
649 received a new method, detach(). detach() disconnects the underlying stream
650 from the buffer or text IO and returns it.
651
Mark Dickinson33841c32009-05-01 15:37:04 +0000652- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
653 floats with absolute value over 1e50. Also remove length
654 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
655 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000656
Eric Smith741191f2009-05-06 13:08:15 +0000657- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000658 format(complex(1, 2./3), '.5') now produces a sensible result.
659
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000660- Issue #5864: Fix empty format code formatting for floats so that it
661 never gives more than the requested number of significant digits.
662
Eric Smith6dc46f52009-04-27 20:39:49 +0000663- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
664 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
665
Eric Smithcc32a112009-04-26 21:35:14 +0000666- Issue #5835: Deprecate PyOS_ascii_formatd.
667
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000668- Issue #4971: Fix titlecase for characters that are their own
669 titlecase, but not their own uppercase.
670
Benjamin Peterson193152c2009-04-25 01:08:45 +0000671- Issue #5283: Setting __class__ in __del__ caused a segfault.
672
Mark Dickinsonad476da2009-04-23 19:14:16 +0000673- Issue #5816: complex(repr(z)) now recovers z exactly, even when
674 z involves nans, infs or negative zeros.
675
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000676- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000677
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000678- Issue #1869 (and many duplicates): make round(x, n) correctly
679 rounded for a float x, by using the decimal <-> binary conversions
680 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
681 consistently agrees with format(x, '.2f').
682
Benjamin Petersonae937c02009-04-18 20:54:08 +0000683- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
684 some builtin types.
685
Eric Smith0923d1d2009-04-16 20:16:10 +0000686- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
687
Eric Smith35e84722009-04-16 20:21:28 +0000688- Issue #5515: str.format() type 'n' combined with commas and leading
689 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000690
691- Implement PEP 378, Format Specifier for Thousands Separator, for
692 floats.
693
Mark Dickinson3370cce2009-04-17 22:40:53 +0000694- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000695 1e11, not 1e12. This avoids printing 13 significant digits in
696 situations where only 12 of them are correct. Example problem
697 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
698 long time.)
699
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000700- Issue #1580: On most platforms, use a 'short' float repr: for a
701 finite float x, repr(x) now outputs a string based on the shortest
702 sequence of decimal digits that rounds to x. Previous behaviour was
703 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000704 Another minor difference is that the new repr switches to
705 exponential notation at 1e16 instead of the previous 1e17; this
706 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000707
708 There's a new sys attribute sys.float_repr_style, which takes
709 the value 'short' to indicate that we're using short float repr,
710 and 'legacy' if the short float repr isn't available for one
711 reason or another.
712
713 The float repr change involves incorporating David Gay's 'perfect
714 rounding' code into the Python core (it's in Python/dtoa.c). As a
715 secondary consequence, all string-to-float and float-to-string
716 conversions (including all float formatting operations) will be
717 correctly rounded on these platforms.
718
719 See issue 1580 discussions for details of platforms for which
720 this change does not apply.
721
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000722- Issue #5759: float() didn't call __float__ on str subclasses.
723
Georg Brandlabc38772009-04-12 15:51:51 +0000724- The string.maketrans() function is deprecated; there is a new static method
725 maketrans() on the bytes and bytearray classes. This removes confusion about
726 the types string.maketrans() is supposed to work with, and mirrors the
727 methods available on the str class.
728
R. David Murraydc6da8a2009-04-09 22:16:43 +0000729- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
730 its clarity and its speed.
731
Matthias Klose091c7b12009-04-07 13:24:27 +0000732- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
733 to avoid compiler warnings.
734
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000735- Issue #3739: The unicode-internal encoder now reports the number of characters
736 consumed like any other encoder (instead of the number of bytes).
737

751
Vinay Sajipaffbd872009-06-11 10:11:47 +0000752- Issue #5940: distutils.command.build_clib.check_library_list was not doing

Antoine Pitrou3a652b12009-03-23 18:52:06 +0000893- Issue #4688: Add a heuristic so that tuples and dicts containing only
894 untrackable objects are not tracked by the garbage collector. This can
895 reduce the size of collections and therefore the garbage collection overhead
896 on long-running programs, depending on their particular use of datatypes.

1017 rotating the object pointer by 4 bits to the right.
1018
Mark Dickinson87ec0852009-02-09 17:15:59 +00001019- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1020 it now forces its argument to double before testing for infinity.
1021
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001022- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1030 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001031
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001032- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001033 were suppressing all exceptions. These include list() and bytearray().
1034
Mark Dickinson1124e712009-01-28 21:25:58 +00001035- Issue #4707: round(x, n) now returns an integer if x is an integer.
1036 Previously it returned a float.
1037
Antoine Pitroub52ec782009-01-25 16:34:23 +00001038- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1039 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1040 evaluation loop is compiled with a new dispatch mechanism which gives
1041 speedups of up to 20%, depending on the system, on various benchmarks.
1042
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001043- Issue #4874: Most builtin decoders now reject unicode input.

1049
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001050- Issue #4838: When a module is deallocated, free the memory backing the
1051 optional module state data.
1052
Mark Dickinson8055afd2009-01-17 10:04:45 +00001053- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1054 type to (void *).
1055
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001056- Issue #4935: The overflow checking code in the expandtabs() method common
1057 to str, bytes and bytearray could be optimized away by the compiler, letting
1058 the interpreter segfault instead of raising an error.
1059
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001060- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1061 __next__ method.
1062
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001063- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1064 function no longer attempt to call the __long__ slot to convert an object
1065 to an integer. Only the __int__ and __trunc__ slots are examined.
1066
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001067- Issue #4893: Use NT threading on CE.
1068
Martin v. Löwisec59d042009-01-12 07:59:10 +00001069- Issue #4915: Port sysmodule to Windows CE.
1070
Antoine Pitrouab868312009-01-10 15:40:25 +00001071- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1072 common cases are optimized thanks to a dedicated fast path and a moderate
1073 amount of loop unrolling.
1074
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001075- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1076 collecting the oldest generation) so that allocating lots of objects without
1077 destroying them does not show quadratic performance. Based on a proposal by
1078 Martin von Löwis at
1079 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1080
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001081- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001082 having been closed (for instance, a read() call could return some
1083 previously buffered data). Patch by Dmitry Vasiliev.
1084
Antoine Pitrou05608432009-01-09 18:53:14 +00001085- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1086 flag to work properly. Furthermore, when specifying -u, the text stdout
1087 and stderr streams have line-by-line buffering enabled (the default being
1088 to buffer arbitrary chunks of data).
1089
Raymond Hettinger35631532009-01-09 03:58:09 +00001090- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1091 instead of ints (reducing its size from 4 to 8 times thereby reducing
1092 Python's overall memory).
1093
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001094- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1095 an existing .py counterpart, override the co_filename attributes of all
1096 code objects if the original filename is obsolete (which can happen if the
1097 file has been renamed, moved, or if it is accessed through different paths).
1098 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1099
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001100- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1101 one byte. Also fixes the meaning of len() so that it returns the number of
1102 items, rather than the size in bytes.
1103
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001104- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1105
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001106- Issue #4747: When the terminal does not use utf-8, executing a script with
1107 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1108
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001109- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001110 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001111
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001112- Issue #3680: Reference cycles created through a dict, set or deque iterator
1113 did not get collected.
1114
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001115- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1116 where the tp_hash and tp_dict slots are both NULL.
1117
Georg Brandlccc47b62008-12-28 11:44:14 +00001118- Issue #4759: None is now allowed as the first argument of
1119 bytearray.translate(). It was always allowed for bytes.translate().
1120
Skip Montanaro80072cb2008-12-23 03:51:14 +00001121- Added test case to ensure attempts to read from a file opened for writing
1122 fail.
1123
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001124- Issue #3106: Speedup some comparisons (str/str and int/int).

1127 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1128
Antoine Pitrou621601a2008-12-17 23:18:19 +00001129- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1130 print elapsed times, not only when some objects are uncollectable /
1131 unreachable. Original patch by Neil Schemenauer.
1132
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001133- Issue #3439: Add a bit_length method to int.
1134
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001135- Issue #2173: When getting device encoding, check that return value of
1136 nl_langinfo is not the empty string. This was causing silent build
1137 failures on OS X.
1138
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001139- Issue #4597: Fixed several opcodes that weren't always propagating
1140 exceptions.
1141
1142- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001143 context manager returns a value that cannot be converted to a bool.
1144
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001145- Issue #4445: Replace "sizeof(PyBytesObject)" with
1146 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1147 bytes instances. On a typical machine this saves 3 bytes of memory
1148 (on average) per allocation of a bytes instance.
1149
Christian Heimesa872de52008-12-05 08:26:55 +00001150- Issue #4533: File read operation was dreadfully slow due to a slowly
1151 growing read buffer. Fixed by using the same growth rate algorithm as
1152 Python 2.x.
1153
Antoine Pitrou5504e892008-12-06 21:27:53 +00001154- Issue #4509: Various issues surrounding resize of bytearray objects to
1155 which there are buffer exports (e.g. memoryview instances).
1156
Georg Brandlf9734072008-12-07 15:30:06 +00001157- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1158 method on file objects with closefd=False. The file descriptor is still
1159 kept open but the file object behaves like a closed file. The ``FileIO``
1160 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001161
Antoine Pitroubc420402008-12-07 20:14:49 +00001162- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001169- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1170 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1171 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1172 of using the replace error handler in PyUnicode_DecodeUTF8().
