552Core and Builtins
553-----------------
554
Mark Dickinson865e01a2009-05-07 16:37:01 +0000555- Issue #5914: Add new C API function PyOS_string_to_double, and
556 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
557
Eric Smith741191f2009-05-06 13:08:15 +0000558- Issue #3382: float.__format__, complex.__format__, and %-formatting
559 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
560 affects nan -> NAN and inf -> INF.
561
Mark Hammond5a607a32009-05-06 08:04:54 +0000562- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
563 in all operations, including splitdrive, split, etc. splitunc() now issues
564 a PendingDeprecation warning.
565
Eric Smith63376222009-05-05 14:04:18 +0000566- Issue #5920: For float.__format__, change the behavior with the
567 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
568 to be like 'g' but with at least one decimal point and with a
569 default precision of 12. Previously, the behavior the same but with
570 a default precision of 6. This more closely matches str(), and
571 reduces surprises when adding alignment flags to the empty
572 presentation type. This also affects the new complex.__format__ in
573 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000586- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
587 received a new method, detach(). detach() disconnects the underlying stream
588 from the buffer or text IO and returns it.
589
Mark Dickinson33841c32009-05-01 15:37:04 +0000590- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
591 floats with absolute value over 1e50. Also remove length
592 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
593 12.34 no longer raise an exception.

Mark Dickinsonc6300392009-04-20 21:38:00 +0000615
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000616- Issue #1869 (and many duplicates): make round(x, n) correctly
617 rounded for a float x, by using the decimal <-> binary conversions
618 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
619 consistently agrees with format(x, '.2f').
620
Benjamin Petersonae937c02009-04-18 20:54:08 +0000621- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
622 some builtin types.
623
Eric Smith0923d1d2009-04-16 20:16:10 +0000624- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
625
Eric Smith35e84722009-04-16 20:21:28 +0000626- Issue #5515: str.format() type 'n' combined with commas and leading
627 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000628
629- Implement PEP 378, Format Specifier for Thousands Separator, for
630 floats.
631
Mark Dickinson3370cce2009-04-17 22:40:53 +0000632- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000633 1e11, not 1e12. This avoids printing 13 significant digits in
634 situations where only 12 of them are correct. Example problem
635 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
636 long time.)
637
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000638- Issue #1580: On most platforms, use a 'short' float repr: for a
639 finite float x, repr(x) now outputs a string based on the shortest
640 sequence of decimal digits that rounds to x. Previous behaviour was
641 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000642 Another minor difference is that the new repr switches to
643 exponential notation at 1e16 instead of the previous 1e17; this
644 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000645
646 There's a new sys attribute sys.float_repr_style, which takes
647 the value 'short' to indicate that we're using short float repr,
648 and 'legacy' if the short float repr isn't available for one
649 reason or another.
650
651 The float repr change involves incorporating David Gay's 'perfect
652 rounding' code into the Python core (it's in Python/dtoa.c). As a
653 secondary consequence, all string-to-float and float-to-string
654 conversions (including all float formatting operations) will be
655 correctly rounded on these platforms.
656
657 See issue 1580 discussions for details of platforms for which
658 this change does not apply.
659
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000660- Issue #5759: float() didn't call __float__ on str subclasses.
661
Georg Brandlabc38772009-04-12 15:51:51 +0000662- The string.maketrans() function is deprecated; there is a new static method
663 maketrans() on the bytes and bytearray classes. This removes confusion about
664 the types string.maketrans() is supposed to work with, and mirrors the
665 methods available on the str class.
666
R. David Murraydc6da8a2009-04-09 22:16:43 +0000667- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Walter Dörwald8dc33d52009-05-06 14:41:26 +0000673- Issue #3739: The unicode-internal encoder now reports the number of characters

Antoine Pitrou3a652b12009-03-23 18:52:06 +0000831- Issue #4688: Add a heuristic so that tuples and dicts containing only
832 untrackable objects are not tracked by the garbage collector. This can
833 reduce the size of collections and therefore the garbage collection overhead
834 on long-running programs, depending on their particular use of datatypes.

929 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
930 have been removed from the struct module.

952 source has already been decoded into str.
953
Antoine Pitrou79eee6b2009-02-13 14:01:05 +0000954- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
955 rotating the object pointer by 4 bits to the right.
956
Mark Dickinson87ec0852009-02-09 17:15:59 +0000957- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
958 it now forces its argument to double before testing for infinity.
959
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000960- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +0000969
Georg Brandl1cdd83c2009-04-05 20:24:29 +0000970- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000971 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +0000973- Issue #4707: round(x, n) now returns an integer if x is an integer.
974 Previously it returned a float.
975
Antoine Pitroub52ec782009-01-25 16:34:23 +0000976- Issue #4753: By enabling a configure option named '--with-computed-gotos'
977 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
978 evaluation loop is compiled with a new dispatch mechanism which gives
979 speedups of up to 20%, depending on the system, on various benchmarks.

987
Antoine Pitroue4bc7f62009-01-17 21:06:43 +0000988- Issue #4838: When a module is deallocated, free the memory backing the
989 optional module state data.
990
Mark Dickinson8055afd2009-01-17 10:04:45 +0000991- Issue #4910: Rename nb_long slot to nb_reserved, and change its
992 type to (void *).
993
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000994- Issue #4935: The overflow checking code in the expandtabs() method common
995 to str, bytes and bytearray could be optimized away by the compiler, letting
996 the interpreter segfault instead of raising an error.
997
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000998- Issue #3720: Fix a crash when an iterator modifies its class and removes its
999 __next__ method.
1000
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001001- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1002 function no longer attempt to call the __long__ slot to convert an object
1003 to an integer. Only the __int__ and __trunc__ slots are examined.
1004
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001005- Issue #4893: Use NT threading on CE.
1006
Martin v. Löwisec59d042009-01-12 07:59:10 +00001007- Issue #4915: Port sysmodule to Windows CE.
1008
Antoine Pitrouab868312009-01-10 15:40:25 +00001009- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1010 common cases are optimized thanks to a dedicated fast path and a moderate
1011 amount of loop unrolling.
1012
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001013- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1014 collecting the oldest generation) so that allocating lots of objects without
1015 destroying them does not show quadratic performance. Based on a proposal by
1016 Martin von Löwis at
1017 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1018
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001019- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001020 having been closed (for instance, a read() call could return some
1021 previously buffered data). Patch by Dmitry Vasiliev.
1022
Antoine Pitrou05608432009-01-09 18:53:14 +00001023- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1024 flag to work properly. Furthermore, when specifying -u, the text stdout
1025 and stderr streams have line-by-line buffering enabled (the default being
1026 to buffer arbitrary chunks of data).
1027
Raymond Hettinger35631532009-01-09 03:58:09 +00001028- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1029 instead of ints (reducing its size from 4 to 8 times thereby reducing
1030 Python's overall memory).
1031
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001032- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1033 an existing .py counterpart, override the co_filename attributes of all
1034 code objects if the original filename is obsolete (which can happen if the
1035 file has been renamed, moved, or if it is accessed through different paths).
1036 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1037
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001038- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1039 one byte. Also fixes the meaning of len() so that it returns the number of
1040 items, rather than the size in bytes.
1041
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001042- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1043
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001044- Issue #4747: When the terminal does not use utf-8, executing a script with
1045 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1046
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001047- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001048 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001049
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001050- Issue #3680: Reference cycles created through a dict, set or deque iterator
1051 did not get collected.
1052
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001053- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1054 where the tp_hash and tp_dict slots are both NULL.
1055
Georg Brandlccc47b62008-12-28 11:44:14 +00001056- Issue #4759: None is now allowed as the first argument of
1057 bytearray.translate(). It was always allowed for bytes.translate().
1058
Skip Montanaro80072cb2008-12-23 03:51:14 +00001059- Added test case to ensure attempts to read from a file opened for writing
1060 fail.

1066
Antoine Pitrou621601a2008-12-17 23:18:19 +00001067- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1068 print elapsed times, not only when some objects are uncollectable /
1069 unreachable. Original patch by Neil Schemenauer.
1070
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001071- Issue #3439: Add a bit_length method to int.
1072
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001073- Issue #2173: When getting device encoding, check that return value of
1074 nl_langinfo is not the empty string. This was causing silent build
1075 failures on OS X.
1076
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001077- Issue #4597: Fixed several opcodes that weren't always propagating
1078 exceptions.
1079
1080- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001081 context manager returns a value that cannot be converted to a bool.
1082
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001083- Issue #4445: Replace "sizeof(PyBytesObject)" with
1084 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1085 bytes instances. On a typical machine this saves 3 bytes of memory
1086 (on average) per allocation of a bytes instance.
1087
Christian Heimesa872de52008-12-05 08:26:55 +00001088- Issue #4533: File read operation was dreadfully slow due to a slowly
1089 growing read buffer. Fixed by using the same growth rate algorithm as
1090 Python 2.x.
1091
Antoine Pitrou5504e892008-12-06 21:27:53 +00001092- Issue #4509: Various issues surrounding resize of bytearray objects to
1093 which there are buffer exports (e.g. memoryview instances).
1094
Georg Brandlf9734072008-12-07 15:30:06 +00001095- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1096 method on file objects with closefd=False. The file descriptor is still
1097 kept open but the file object behaves like a closed file. The ``FileIO``
1098 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001099
Antoine Pitroubc420402008-12-07 20:14:49 +00001100- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1106
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001107- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1108 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1109 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1110 of using the replace error handler in PyUnicode_DecodeUTF8().
