572 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.

Eric Smith741191f2009-05-06 13:08:15 +0000574- Issue #3382: float.__format__, complex.__format__, and %-formatting
575 no longer map 'F' to 'f'. Because of issue #5859 (below), this only

579 in all operations, including splitdrive, split, etc. splitunc() now issues
580 a PendingDeprecation warning.
581
Eric Smith63376222009-05-05 14:04:18 +0000582- Issue #5920: For float.__format__, change the behavior with the
583 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
584 to be like 'g' but with at least one decimal point and with a
585 default precision of 12. Previously, the behavior the same but with
586 a default precision of 6. This more closely matches str(), and
587 reduces surprises when adding alignment flags to the empty
588 presentation type. This also affects the new complex.__format__ in

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000602- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
603 received a new method, detach(). detach() disconnects the underlying stream
604 from the buffer or text IO and returns it.
605
Mark Dickinson33841c32009-05-01 15:37:04 +0000606- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
607 floats with absolute value over 1e50. Also remove length
608 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
609 12.34 no longer raise an exception.

Mark Dickinsonc6300392009-04-20 21:38:00 +0000631
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000632- Issue #1869 (and many duplicates): make round(x, n) correctly
633 rounded for a float x, by using the decimal <-> binary conversions
634 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
635 consistently agrees with format(x, '.2f').
636
Benjamin Petersonae937c02009-04-18 20:54:08 +0000637- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

641
Eric Smith35e84722009-04-16 20:21:28 +0000642- Issue #5515: str.format() type 'n' combined with commas and leading
643 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000644
645- Implement PEP 378, Format Specifier for Thousands Separator, for
646 floats.
647
Mark Dickinson3370cce2009-04-17 22:40:53 +0000648- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000649 1e11, not 1e12. This avoids printing 13 significant digits in
650 situations where only 12 of them are correct. Example problem
651 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
652 long time.)
653
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000654- Issue #1580: On most platforms, use a 'short' float repr: for a
655 finite float x, repr(x) now outputs a string based on the shortest
656 sequence of decimal digits that rounds to x. Previous behaviour was
657 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000658 Another minor difference is that the new repr switches to
659 exponential notation at 1e16 instead of the previous 1e17; this
660 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000661
662 There's a new sys attribute sys.float_repr_style, which takes
663 the value 'short' to indicate that we're using short float repr,
664 and 'legacy' if the short float repr isn't available for one
665 reason or another.
666
667 The float repr change involves incorporating David Gay's 'perfect
668 rounding' code into the Python core (it's in Python/dtoa.c). As a
669 secondary consequence, all string-to-float and float-to-string
670 conversions (including all float formatting operations) will be
671 correctly rounded on these platforms.
672
673 See issue 1580 discussions for details of platforms for which
674 this change does not apply.
675
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000676- Issue #5759: float() didn't call __float__ on str subclasses.
677
Georg Brandlabc38772009-04-12 15:51:51 +0000678- The string.maketrans() function is deprecated; there is a new static method
679 maketrans() on the bytes and bytearray classes. This removes confusion about
680 the types string.maketrans() is supposed to work with, and mirrors the
681 methods available on the str class.
682
R. David Murraydc6da8a2009-04-09 22:16:43 +0000683- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

849 reduce the size of collections and therefore the garbage collection overhead
850 on long-running programs, depending on their particular use of datatypes.

971 rotating the object pointer by 4 bits to the right.
972
Mark Dickinson87ec0852009-02-09 17:15:59 +0000973- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
974 it now forces its argument to double before testing for infinity.
975
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000976- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +0000985
Georg Brandl1cdd83c2009-04-05 20:24:29 +0000986- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +0000987 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +0000989- Issue #4707: round(x, n) now returns an integer if x is an integer.
990 Previously it returned a float.
991
Antoine Pitroub52ec782009-01-25 16:34:23 +0000992- Issue #4753: By enabling a configure option named '--with-computed-gotos'
993 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
994 evaluation loop is compiled with a new dispatch mechanism which gives
995 speedups of up to 20%, depending on the system, on various benchmarks.
996
Antoine Pitrou81fabdb2009-01-22 10:11:36 +0000997- Issue #4874: Most builtin decoders now reject unicode input.

1003
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001004- Issue #4838: When a module is deallocated, free the memory backing the
1005 optional module state data.
1006
Mark Dickinson8055afd2009-01-17 10:04:45 +00001007- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1008 type to (void *).
1009
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001010- Issue #4935: The overflow checking code in the expandtabs() method common
1011 to str, bytes and bytearray could be optimized away by the compiler, letting
1012 the interpreter segfault instead of raising an error.
1013
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001014- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1015 __next__ method.
1016
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001017- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1018 function no longer attempt to call the __long__ slot to convert an object
1019 to an integer. Only the __int__ and __trunc__ slots are examined.
1020
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001021- Issue #4893: Use NT threading on CE.
1022
Martin v. Löwisec59d042009-01-12 07:59:10 +00001023- Issue #4915: Port sysmodule to Windows CE.
1024
Antoine Pitrouab868312009-01-10 15:40:25 +00001025- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1026 common cases are optimized thanks to a dedicated fast path and a moderate
1027 amount of loop unrolling.
1028
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001029- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1030 collecting the oldest generation) so that allocating lots of objects without
1031 destroying them does not show quadratic performance. Based on a proposal by
1032 Martin von Löwis at
1033 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1034
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001035- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001036 having been closed (for instance, a read() call could return some
1037 previously buffered data). Patch by Dmitry Vasiliev.
1038
Antoine Pitrou05608432009-01-09 18:53:14 +00001039- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1040 flag to work properly. Furthermore, when specifying -u, the text stdout
1041 and stderr streams have line-by-line buffering enabled (the default being
1042 to buffer arbitrary chunks of data).
1043
Raymond Hettinger35631532009-01-09 03:58:09 +00001044- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1045 instead of ints (reducing its size from 4 to 8 times thereby reducing
1046 Python's overall memory).
1047
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001048- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1049 an existing .py counterpart, override the co_filename attributes of all
1050 code objects if the original filename is obsolete (which can happen if the
1051 file has been renamed, moved, or if it is accessed through different paths).
1052 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1053
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001054- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1055 one byte. Also fixes the meaning of len() so that it returns the number of
1056 items, rather than the size in bytes.
1057
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001058- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1059
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001060- Issue #4747: When the terminal does not use utf-8, executing a script with
1061 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1062
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001063- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001064 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001065
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001066- Issue #3680: Reference cycles created through a dict, set or deque iterator
1067 did not get collected.
1068
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001069- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1070 where the tp_hash and tp_dict slots are both NULL.
1071
Georg Brandlccc47b62008-12-28 11:44:14 +00001072- Issue #4759: None is now allowed as the first argument of
1073 bytearray.translate(). It was always allowed for bytes.translate().
1074
Skip Montanaro80072cb2008-12-23 03:51:14 +00001075- Added test case to ensure attempts to read from a file opened for writing
1076 fail.
1077
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001078- Issue #3106: Speedup some comparisons (str/str and int/int).

1081 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1082
Antoine Pitrou621601a2008-12-17 23:18:19 +00001083- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1084 print elapsed times, not only when some objects are uncollectable /
1085 unreachable. Original patch by Neil Schemenauer.
1086
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001087- Issue #3439: Add a bit_length method to int.
1088
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001089- Issue #2173: When getting device encoding, check that return value of
1090 nl_langinfo is not the empty string. This was causing silent build
1091 failures on OS X.
1092
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001093- Issue #4597: Fixed several opcodes that weren't always propagating
1094 exceptions.
1095
1096- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001097 context manager returns a value that cannot be converted to a bool.
1098
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001099- Issue #4445: Replace "sizeof(PyBytesObject)" with
1100 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1101 bytes instances. On a typical machine this saves 3 bytes of memory
1102 (on average) per allocation of a bytes instance.
1103
Christian Heimesa872de52008-12-05 08:26:55 +00001104- Issue #4533: File read operation was dreadfully slow due to a slowly
1105 growing read buffer. Fixed by using the same growth rate algorithm as
1106 Python 2.x.
1107
Antoine Pitrou5504e892008-12-06 21:27:53 +00001108- Issue #4509: Various issues surrounding resize of bytearray objects to
1109 which there are buffer exports (e.g. memoryview instances).
1110
Georg Brandlf9734072008-12-07 15:30:06 +00001111- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1112 method on file objects with closefd=False. The file descriptor is still
1113 kept open but the file object behaves like a closed file. The ``FileIO``
1114 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001115
Antoine Pitroubc420402008-12-07 20:14:49 +00001116- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1122
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001123- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1124 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1125 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1126 of using the replace error handler in PyUnicode_DecodeUTF8().
