566Core and Builtins
567-----------------
568
Mark Dickinson865e01a2009-05-07 16:37:01 +0000569- Issue #5914: Add new C API function PyOS_string_to_double, and
570 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
571
Eric Smith741191f2009-05-06 13:08:15 +0000572- Issue #3382: float.__format__, complex.__format__, and %-formatting
573 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
574 affects nan -> NAN and inf -> INF.
575
Mark Hammond5a607a32009-05-06 08:04:54 +0000576- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
577 in all operations, including splitdrive, split, etc. splitunc() now issues
578 a PendingDeprecation warning.
579
Eric Smith63376222009-05-05 14:04:18 +0000580- Issue #5920: For float.__format__, change the behavior with the
581 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
582 to be like 'g' but with at least one decimal point and with a
583 default precision of 12. Previously, the behavior the same but with
584 a default precision of 6. This more closely matches str(), and
585 reduces surprises when adding alignment flags to the empty
586 presentation type. This also affects the new complex.__format__ in
587 the same way.
588
Martin v. Löwis011e8422009-05-05 04:43:17 +0000589- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000600- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
601 received a new method, detach(). detach() disconnects the underlying stream
602 from the buffer or text IO and returns it.
603
Mark Dickinson33841c32009-05-01 15:37:04 +0000604- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
605 floats with absolute value over 1e50. Also remove length
606 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
607 12.34 no longer raise an exception.

Mark Dickinsone6a076d2009-04-18 11:48:33 +0000630- Issue #1869 (and many duplicates): make round(x, n) correctly
631 rounded for a float x, by using the decimal <-> binary conversions
632 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
633 consistently agrees with format(x, '.2f').
634
Benjamin Petersonae937c02009-04-18 20:54:08 +0000635- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith0923d1d2009-04-16 20:16:10 +0000638- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
639
Eric Smith35e84722009-04-16 20:21:28 +0000640- Issue #5515: str.format() type 'n' combined with commas and leading
641 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000642
643- Implement PEP 378, Format Specifier for Thousands Separator, for
644 floats.
645
Mark Dickinson3370cce2009-04-17 22:40:53 +0000646- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000647 1e11, not 1e12. This avoids printing 13 significant digits in
648 situations where only 12 of them are correct. Example problem
649 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
650 long time.)
651
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000652- Issue #1580: On most platforms, use a 'short' float repr: for a
653 finite float x, repr(x) now outputs a string based on the shortest
654 sequence of decimal digits that rounds to x. Previous behaviour was
655 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000656 Another minor difference is that the new repr switches to
657 exponential notation at 1e16 instead of the previous 1e17; this
658 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000659
660 There's a new sys attribute sys.float_repr_style, which takes
661 the value 'short' to indicate that we're using short float repr,
662 and 'legacy' if the short float repr isn't available for one
663 reason or another.
664
665 The float repr change involves incorporating David Gay's 'perfect
666 rounding' code into the Python core (it's in Python/dtoa.c). As a
667 secondary consequence, all string-to-float and float-to-string
668 conversions (including all float formatting operations) will be
669 correctly rounded on these platforms.
670
671 See issue 1580 discussions for details of platforms for which
672 this change does not apply.
673
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000674- Issue #5759: float() didn't call __float__ on str subclasses.
675
Georg Brandlabc38772009-04-12 15:51:51 +0000676- The string.maketrans() function is deprecated; there is a new static method
677 maketrans() on the bytes and bytearray classes. This removes confusion about
678 the types string.maketrans() is supposed to work with, and mirrors the
679 methods available on the str class.
680
R. David Murraydc6da8a2009-04-09 22:16:43 +0000681- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

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

Antoine Pitrou0ae29cf2009-03-13 22:33:17 +0000929- The error detection code in FileIO.close() could fail to reflect the `errno`
930 value, and report it as -1 instead.
931

Mark Dickinsonb40b9472009-03-29 16:58:21 +0000942 struct.error instead of returning b'\xff\xff\xff\xff'. The
943 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
944 have been removed from the struct module.

963 contained non ascii character on windows.
964
Benjamin Petersonf5b52242009-03-02 23:31:26 +0000965- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
966 source has already been decoded into str.
967
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000968- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
969 rotating the object pointer by 4 bits to the right.
970
Mark Dickinson87ec0852009-02-09 17:15:59 +0000971- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
972 it now forces its argument to double before testing for infinity.
973
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000974- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +0000983
Georg Brandl1cdd83c2009-04-05 20:24:29 +0000984- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000985 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +0000987- Issue #4707: round(x, n) now returns an integer if x is an integer.
988 Previously it returned a float.
989
Antoine Pitroub52ec782009-01-25 16:34:23 +0000990- Issue #4753: By enabling a configure option named '--with-computed-gotos'
991 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
992 evaluation loop is compiled with a new dispatch mechanism which gives
993 speedups of up to 20%, depending on the system, on various benchmarks.
994
Antoine Pitrou81fabdb2009-01-22 10:11:36 +0000995- Issue #4874: Most builtin decoders now reject unicode input.

1001
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001002- Issue #4838: When a module is deallocated, free the memory backing the
1003 optional module state data.
1004
Mark Dickinson8055afd2009-01-17 10:04:45 +00001005- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1006 type to (void *).
1007
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001008- Issue #4935: The overflow checking code in the expandtabs() method common
1009 to str, bytes and bytearray could be optimized away by the compiler, letting
1010 the interpreter segfault instead of raising an error.
1011
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001012- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1013 __next__ method.
1014
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001015- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1016 function no longer attempt to call the __long__ slot to convert an object
1017 to an integer. Only the __int__ and __trunc__ slots are examined.
1018
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001019- Issue #4893: Use NT threading on CE.
1020
Martin v. Löwisec59d042009-01-12 07:59:10 +00001021- Issue #4915: Port sysmodule to Windows CE.
1022
Antoine Pitrouab868312009-01-10 15:40:25 +00001023- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1024 common cases are optimized thanks to a dedicated fast path and a moderate
1025 amount of loop unrolling.
1026
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001027- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1028 collecting the oldest generation) so that allocating lots of objects without
1029 destroying them does not show quadratic performance. Based on a proposal by
1030 Martin von Löwis at
1031 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1032
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001033- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001034 having been closed (for instance, a read() call could return some
1035 previously buffered data). Patch by Dmitry Vasiliev.
1036
Antoine Pitrou05608432009-01-09 18:53:14 +00001037- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1038 flag to work properly. Furthermore, when specifying -u, the text stdout
1039 and stderr streams have line-by-line buffering enabled (the default being
1040 to buffer arbitrary chunks of data).
1041
Raymond Hettinger35631532009-01-09 03:58:09 +00001042- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1043 instead of ints (reducing its size from 4 to 8 times thereby reducing
1044 Python's overall memory).
1045
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001046- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1047 an existing .py counterpart, override the co_filename attributes of all
1048 code objects if the original filename is obsolete (which can happen if the
1049 file has been renamed, moved, or if it is accessed through different paths).
1050 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1051
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001052- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1053 one byte. Also fixes the meaning of len() so that it returns the number of
1054 items, rather than the size in bytes.
1055
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001056- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1057
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001058- Issue #4747: When the terminal does not use utf-8, executing a script with
1059 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1060
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001061- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001062 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001063
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001064- Issue #3680: Reference cycles created through a dict, set or deque iterator
1065 did not get collected.
1066
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001067- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1068 where the tp_hash and tp_dict slots are both NULL.
1069
Georg Brandlccc47b62008-12-28 11:44:14 +00001070- Issue #4759: None is now allowed as the first argument of
1071 bytearray.translate(). It was always allowed for bytes.translate().
1072
Skip Montanaro80072cb2008-12-23 03:51:14 +00001073- Added test case to ensure attempts to read from a file opened for writing
1074 fail.
1075
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001076- Issue #3106: Speedup some comparisons (str/str and int/int).

1080
Antoine Pitrou621601a2008-12-17 23:18:19 +00001081- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1082 print elapsed times, not only when some objects are uncollectable /
1083 unreachable. Original patch by Neil Schemenauer.
1084
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001085- Issue #3439: Add a bit_length method to int.
1086
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001087- Issue #2173: When getting device encoding, check that return value of
1088 nl_langinfo is not the empty string. This was causing silent build
1089 failures on OS X.
1090
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001091- Issue #4597: Fixed several opcodes that weren't always propagating
1092 exceptions.
1093
1094- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001095 context manager returns a value that cannot be converted to a bool.
1096
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001097- Issue #4445: Replace "sizeof(PyBytesObject)" with
1098 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1099 bytes instances. On a typical machine this saves 3 bytes of memory
1100 (on average) per allocation of a bytes instance.
1101
Christian Heimesa872de52008-12-05 08:26:55 +00001102- Issue #4533: File read operation was dreadfully slow due to a slowly
1103 growing read buffer. Fixed by using the same growth rate algorithm as
1104 Python 2.x.
1105
Antoine Pitrou5504e892008-12-06 21:27:53 +00001106- Issue #4509: Various issues surrounding resize of bytearray objects to
1107 which there are buffer exports (e.g. memoryview instances).
1108
Georg Brandlf9734072008-12-07 15:30:06 +00001109- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1110 method on file objects with closefd=False. The file descriptor is still
1111 kept open but the file object behaves like a closed file. The ``FileIO``
1112 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001113
Antoine Pitroubc420402008-12-07 20:14:49 +00001114- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1120
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001121- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1122 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1123 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1124 of using the replace error handler in PyUnicode_DecodeUTF8().
