575Core and Builtins
576-----------------
577
Mark Dickinson865e01a2009-05-07 16:37:01 +0000578- Issue #5914: Add new C API function PyOS_string_to_double, and
579 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
580
Eric Smith741191f2009-05-06 13:08:15 +0000581- Issue #3382: float.__format__, complex.__format__, and %-formatting
582 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
583 affects nan -> NAN and inf -> INF.
584
Mark Hammond5a607a32009-05-06 08:04:54 +0000585- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
586 in all operations, including splitdrive, split, etc. splitunc() now issues
587 a PendingDeprecation warning.
588
Eric Smith63376222009-05-05 14:04:18 +0000589- Issue #5920: For float.__format__, change the behavior with the
590 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
591 to be like 'g' but with at least one decimal point and with a
592 default precision of 12. Previously, the behavior the same but with
593 a default precision of 6. This more closely matches str(), and
594 reduces surprises when adding alignment flags to the empty
595 presentation type. This also affects the new complex.__format__ in
596 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000609- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have

Mark Dickinson33841c32009-05-01 15:37:04 +0000613- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
614 floats with absolute value over 1e50. Also remove length
615 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
616 12.34 no longer raise an exception.

Mark Dickinsone6a076d2009-04-18 11:48:33 +0000639- Issue #1869 (and many duplicates): make round(x, n) correctly
640 rounded for a float x, by using the decimal <-> binary conversions
641 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
642 consistently agrees with format(x, '.2f').
643
Benjamin Petersonae937c02009-04-18 20:54:08 +0000644- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith35e84722009-04-16 20:21:28 +0000649- Issue #5515: str.format() type 'n' combined with commas and leading
650 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000651
652- Implement PEP 378, Format Specifier for Thousands Separator, for
653 floats.
654
Mark Dickinson3370cce2009-04-17 22:40:53 +0000655- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000656 1e11, not 1e12. This avoids printing 13 significant digits in
657 situations where only 12 of them are correct. Example problem
658 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
659 long time.)
660
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000661- Issue #1580: On most platforms, use a 'short' float repr: for a
662 finite float x, repr(x) now outputs a string based on the shortest
663 sequence of decimal digits that rounds to x. Previous behaviour was
664 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000665 Another minor difference is that the new repr switches to
666 exponential notation at 1e16 instead of the previous 1e17; this
667 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000668
669 There's a new sys attribute sys.float_repr_style, which takes
670 the value 'short' to indicate that we're using short float repr,
671 and 'legacy' if the short float repr isn't available for one
672 reason or another.
673
674 The float repr change involves incorporating David Gay's 'perfect
675 rounding' code into the Python core (it's in Python/dtoa.c). As a
676 secondary consequence, all string-to-float and float-to-string
677 conversions (including all float formatting operations) will be
678 correctly rounded on these platforms.
679
680 See issue 1580 discussions for details of platforms for which
681 this change does not apply.
682
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000683- Issue #5759: float() didn't call __float__ on str subclasses.
684
Georg Brandlabc38772009-04-12 15:51:51 +0000685- The string.maketrans() function is deprecated; there is a new static method
686 maketrans() on the bytes and bytearray classes. This removes confusion about
687 the types string.maketrans() is supposed to work with, and mirrors the
688 methods available on the str class.
689
R. David Murraydc6da8a2009-04-09 22:16:43 +0000690- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Benjamin Peterson59406a92009-03-26 17:10:29 +0000924- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
925 io.BufferedRandom have been deprecated for removal in Python 3.2.
926
Lars Gustäbel42e00912009-03-22 20:34:29 +0000927- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
928 forever on incomplete input. That caused tarfile.open() to hang when used
929 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
930 partial bzip2 compressed data.
931
Mark Dickinson79f52032009-03-17 23:12:51 +0000932- Issue #2110: Add support for thousands separator and 'n' type

936 '>' alignment characters.
937
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +0000938- The error detection code in FileIO.close() could fail to reflect the `errno`
939 value, and report it as -1 instead.
940
Antoine Pitroua28fcfd2009-03-13 23:42:55 +0000941- Issue #5016: FileIO.seekable() could return False if the file position

Mark Dickinsonae681df2009-03-21 10:26:31 +0000949- Issue #5463: In struct module, remove deprecated overflow wrapping
950 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +0000951 struct.error instead of returning b'\xff\xff\xff\xff'. The
952 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
953 have been removed from the struct module.

975 source has already been decoded into str.
976
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000977- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
978 rotating the object pointer by 4 bits to the right.
979
Mark Dickinson87ec0852009-02-09 17:15:59 +0000980- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
981 it now forces its argument to double before testing for infinity.
982
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000983- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

991 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +0000992
Georg Brandl1cdd83c2009-04-05 20:24:29 +0000993- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000994 were suppressing all exceptions. These include list() and bytearray().
995
Mark Dickinson1124e712009-01-28 21:25:58 +0000996- Issue #4707: round(x, n) now returns an integer if x is an integer.
997 Previously it returned a float.
998
Antoine Pitroub52ec782009-01-25 16:34:23 +0000999- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1000 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1001 evaluation loop is compiled with a new dispatch mechanism which gives
1002 speedups of up to 20%, depending on the system, on various benchmarks.
1003
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001004- Issue #4874: Most builtin decoders now reject unicode input.

1010
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001011- Issue #4838: When a module is deallocated, free the memory backing the
1012 optional module state data.
1013
Mark Dickinson8055afd2009-01-17 10:04:45 +00001014- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1015 type to (void *).
1016
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001017- Issue #4935: The overflow checking code in the expandtabs() method common
1018 to str, bytes and bytearray could be optimized away by the compiler, letting
1019 the interpreter segfault instead of raising an error.
1020
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001021- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1022 __next__ method.
1023
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001024- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1025 function no longer attempt to call the __long__ slot to convert an object
1026 to an integer. Only the __int__ and __trunc__ slots are examined.
1027
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001028- Issue #4893: Use NT threading on CE.
1029
Martin v. Löwisec59d042009-01-12 07:59:10 +00001030- Issue #4915: Port sysmodule to Windows CE.
1031
Antoine Pitrouab868312009-01-10 15:40:25 +00001032- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1033 common cases are optimized thanks to a dedicated fast path and a moderate
1034 amount of loop unrolling.
1035
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001036- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1037 collecting the oldest generation) so that allocating lots of objects without
1038 destroying them does not show quadratic performance. Based on a proposal by
1039 Martin von Löwis at
1040 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1041
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001042- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001043 having been closed (for instance, a read() call could return some
1044 previously buffered data). Patch by Dmitry Vasiliev.
1045
Antoine Pitrou05608432009-01-09 18:53:14 +00001046- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1047 flag to work properly. Furthermore, when specifying -u, the text stdout
1048 and stderr streams have line-by-line buffering enabled (the default being
1049 to buffer arbitrary chunks of data).
1050
Raymond Hettinger35631532009-01-09 03:58:09 +00001051- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1052 instead of ints (reducing its size from 4 to 8 times thereby reducing
1053 Python's overall memory).
1054
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001055- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1056 an existing .py counterpart, override the co_filename attributes of all
1057 code objects if the original filename is obsolete (which can happen if the
1058 file has been renamed, moved, or if it is accessed through different paths).
1059 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1060
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001061- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1062 one byte. Also fixes the meaning of len() so that it returns the number of
1063 items, rather than the size in bytes.
1064
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001065- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1066
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001067- Issue #4747: When the terminal does not use utf-8, executing a script with
1068 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1069
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001070- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001071 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001072
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001073- Issue #3680: Reference cycles created through a dict, set or deque iterator
1074 did not get collected.
1075
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001076- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1077 where the tp_hash and tp_dict slots are both NULL.
1078
Georg Brandlccc47b62008-12-28 11:44:14 +00001079- Issue #4759: None is now allowed as the first argument of
1080 bytearray.translate(). It was always allowed for bytes.translate().
1081
Skip Montanaro80072cb2008-12-23 03:51:14 +00001082- Added test case to ensure attempts to read from a file opened for writing
1083 fail.
1084
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001085- Issue #3106: Speedup some comparisons (str/str and int/int).

1088 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1089
Antoine Pitrou621601a2008-12-17 23:18:19 +00001090- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1091 print elapsed times, not only when some objects are uncollectable /
1092 unreachable. Original patch by Neil Schemenauer.
1093
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001094- Issue #3439: Add a bit_length method to int.
1095
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001096- Issue #2173: When getting device encoding, check that return value of
1097 nl_langinfo is not the empty string. This was causing silent build
1098 failures on OS X.
1099
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001100- Issue #4597: Fixed several opcodes that weren't always propagating
1101 exceptions.
1102
1103- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001104 context manager returns a value that cannot be converted to a bool.
1105
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001106- Issue #4445: Replace "sizeof(PyBytesObject)" with
1107 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1108 bytes instances. On a typical machine this saves 3 bytes of memory
1109 (on average) per allocation of a bytes instance.
1110
Christian Heimesa872de52008-12-05 08:26:55 +00001111- Issue #4533: File read operation was dreadfully slow due to a slowly
1112 growing read buffer. Fixed by using the same growth rate algorithm as
1113 Python 2.x.
1114
Antoine Pitrou5504e892008-12-06 21:27:53 +00001115- Issue #4509: Various issues surrounding resize of bytearray objects to
1116 which there are buffer exports (e.g. memoryview instances).
1117
Georg Brandlf9734072008-12-07 15:30:06 +00001118- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1119 method on file objects with closefd=False. The file descriptor is still
1120 kept open but the file object behaves like a closed file. The ``FileIO``
1121 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001122
Antoine Pitroubc420402008-12-07 20:14:49 +00001123- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1129
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001130- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1131 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1132 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1133 of using the replace error handler in PyUnicode_DecodeUTF8().
