556Core and Builtins
557-----------------
558
Mark Dickinson865e01a2009-05-07 16:37:01 +0000559- Issue #5914: Add new C API function PyOS_string_to_double, and
560 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
561
Eric Smith741191f2009-05-06 13:08:15 +0000562- Issue #3382: float.__format__, complex.__format__, and %-formatting
563 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
564 affects nan -> NAN and inf -> INF.
565
Mark Hammond5a607a32009-05-06 08:04:54 +0000566- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
567 in all operations, including splitdrive, split, etc. splitunc() now issues
568 a PendingDeprecation warning.
569
Eric Smith63376222009-05-05 14:04:18 +0000570- Issue #5920: For float.__format__, change the behavior with the
571 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
572 to be like 'g' but with at least one decimal point and with a
573 default precision of 12. Previously, the behavior the same but with
574 a default precision of 6. This more closely matches str(), and
575 reduces surprises when adding alignment flags to the empty
576 presentation type. This also affects the new complex.__format__ in
577 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000590- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
591 received a new method, detach(). detach() disconnects the underlying stream
592 from the buffer or text IO and returns it.
593
Mark Dickinson33841c32009-05-01 15:37:04 +0000594- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
595 floats with absolute value over 1e50. Also remove length
596 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Eric Smith6dc46f52009-04-27 20:39:49 +0000605- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
606 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.

Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000618- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000619
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000620- Issue #1869 (and many duplicates): make round(x, n) correctly
621 rounded for a float x, by using the decimal <-> binary conversions
622 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
623 consistently agrees with format(x, '.2f').
624
Benjamin Petersonae937c02009-04-18 20:54:08 +0000625- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
626 some builtin types.
627
Eric Smith0923d1d2009-04-16 20:16:10 +0000628- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
629
Eric Smith35e84722009-04-16 20:21:28 +0000630- Issue #5515: str.format() type 'n' combined with commas and leading
631 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000632
633- Implement PEP 378, Format Specifier for Thousands Separator, for
634 floats.
635
Mark Dickinson3370cce2009-04-17 22:40:53 +0000636- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000637 1e11, not 1e12. This avoids printing 13 significant digits in
638 situations where only 12 of them are correct. Example problem
639 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
640 long time.)
641
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000642- Issue #1580: On most platforms, use a 'short' float repr: for a
643 finite float x, repr(x) now outputs a string based on the shortest
644 sequence of decimal digits that rounds to x. Previous behaviour was
645 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000646 Another minor difference is that the new repr switches to
647 exponential notation at 1e16 instead of the previous 1e17; this
648 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000649
650 There's a new sys attribute sys.float_repr_style, which takes
651 the value 'short' to indicate that we're using short float repr,
652 and 'legacy' if the short float repr isn't available for one
653 reason or another.
654
655 The float repr change involves incorporating David Gay's 'perfect
656 rounding' code into the Python core (it's in Python/dtoa.c). As a
657 secondary consequence, all string-to-float and float-to-string
658 conversions (including all float formatting operations) will be
659 correctly rounded on these platforms.
660
661 See issue 1580 discussions for details of platforms for which
662 this change does not apply.
663
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000664- Issue #5759: float() didn't call __float__ on str subclasses.
665
Georg Brandlabc38772009-04-12 15:51:51 +0000666- The string.maketrans() function is deprecated; there is a new static method
667 maketrans() on the bytes and bytearray classes. This removes confusion about
668 the types string.maketrans() is supposed to work with, and mirrors the
669 methods available on the str class.
670
R. David Murraydc6da8a2009-04-09 22:16:43 +0000671- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

836 untrackable objects are not tracked by the garbage collector. This can
837 reduce the size of collections and therefore the garbage collection overhead
838 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonb40b9472009-03-29 16:58:21 +0000932 struct.error instead of returning b'\xff\xff\xff\xff'. The
933 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
934 have been removed from the struct module.

960
Mark Dickinson87ec0852009-02-09 17:15:59 +0000961- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
962 it now forces its argument to double before testing for infinity.
963
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000964- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +0000973
Georg Brandl1cdd83c2009-04-05 20:24:29 +0000974- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000975 were suppressing all exceptions. These include list() and bytearray().

978 Previously it returned a float.
979
Antoine Pitroub52ec782009-01-25 16:34:23 +0000980- Issue #4753: By enabling a configure option named '--with-computed-gotos'
981 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
982 evaluation loop is compiled with a new dispatch mechanism which gives
983 speedups of up to 20%, depending on the system, on various benchmarks.

991
Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000992- Issue #4838: When a module is deallocated, free the memory backing the
993 optional module state data.
994
Mark Dickinson8055afd2009-01-17 10:04:45 +0000995- Issue #4910: Rename nb_long slot to nb_reserved, and change its
996 type to (void *).
997
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000998- Issue #4935: The overflow checking code in the expandtabs() method common
999 to str, bytes and bytearray could be optimized away by the compiler, letting
1000 the interpreter segfault instead of raising an error.
1001
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001002- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1003 __next__ method.
1004
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001005- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1006 function no longer attempt to call the __long__ slot to convert an object
1007 to an integer. Only the __int__ and __trunc__ slots are examined.
1008
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001009- Issue #4893: Use NT threading on CE.

1012
Antoine Pitrouab868312009-01-10 15:40:25 +00001013- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1014 common cases are optimized thanks to a dedicated fast path and a moderate
1015 amount of loop unrolling.
1016
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001017- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1018 collecting the oldest generation) so that allocating lots of objects without
1019 destroying them does not show quadratic performance. Based on a proposal by
1020 Martin von Löwis at
1021 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1022
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001023- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001024 having been closed (for instance, a read() call could return some
1025 previously buffered data). Patch by Dmitry Vasiliev.
1026
Antoine Pitrou05608432009-01-09 18:53:14 +00001027- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1028 flag to work properly. Furthermore, when specifying -u, the text stdout
1029 and stderr streams have line-by-line buffering enabled (the default being
1030 to buffer arbitrary chunks of data).
1031
Raymond Hettinger35631532009-01-09 03:58:09 +00001032- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1033 instead of ints (reducing its size from 4 to 8 times thereby reducing
1034 Python's overall memory).
1035
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001036- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1037 an existing .py counterpart, override the co_filename attributes of all
1038 code objects if the original filename is obsolete (which can happen if the
1039 file has been renamed, moved, or if it is accessed through different paths).
1040 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1041
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001042- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1043 one byte. Also fixes the meaning of len() so that it returns the number of
1044 items, rather than the size in bytes.
1045
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001046- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1047
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001048- Issue #4747: When the terminal does not use utf-8, executing a script with
1049 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1050
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001051- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001052 file with `bytes' filename on Windows.

1055 did not get collected.
1056
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001057- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1058 where the tp_hash and tp_dict slots are both NULL.
1059
Georg Brandlccc47b62008-12-28 11:44:14 +00001060- Issue #4759: None is now allowed as the first argument of
1061 bytearray.translate(). It was always allowed for bytes.translate().
1062
Skip Montanaro80072cb2008-12-23 03:51:14 +00001063- Added test case to ensure attempts to read from a file opened for writing
1064 fail.

1070
Antoine Pitrou621601a2008-12-17 23:18:19 +00001071- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1072 print elapsed times, not only when some objects are uncollectable /
1073 unreachable. Original patch by Neil Schemenauer.
1074

1076
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001077- Issue #2173: When getting device encoding, check that return value of
1078 nl_langinfo is not the empty string. This was causing silent build
1079 failures on OS X.
1080
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001081- Issue #4597: Fixed several opcodes that weren't always propagating
1082 exceptions.
1083
1084- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001085 context manager returns a value that cannot be converted to a bool.
1086
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001087- Issue #4445: Replace "sizeof(PyBytesObject)" with
1088 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1089 bytes instances. On a typical machine this saves 3 bytes of memory
1090 (on average) per allocation of a bytes instance.
1091
Christian Heimesa872de52008-12-05 08:26:55 +00001092- Issue #4533: File read operation was dreadfully slow due to a slowly
1093 growing read buffer. Fixed by using the same growth rate algorithm as
1094 Python 2.x.
1095
Antoine Pitrou5504e892008-12-06 21:27:53 +00001096- Issue #4509: Various issues surrounding resize of bytearray objects to
1097 which there are buffer exports (e.g. memoryview instances).
1098
Georg Brandlf9734072008-12-07 15:30:06 +00001099- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1100 method on file objects with closefd=False. The file descriptor is still
1101 kept open but the file object behaves like a closed file. The ``FileIO``
1102 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001103
Antoine Pitroubc420402008-12-07 20:14:49 +00001104- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1110
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001111- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1112 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1113 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1114 of using the replace error handler in PyUnicode_DecodeUTF8().
