Mark Dickinson865e01a2009-05-07 16:37:01 +0000584- Issue #5914: Add new C API function PyOS_string_to_double, and
585 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.

598 default precision of 12. Previously, the behavior the same but with
599 a default precision of 6. This more closely matches str(), and
600 reduces surprises when adding alignment flags to the empty
601 presentation type. This also affects the new complex.__format__ in
602 the same way.

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000615- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
616 received a new method, detach(). detach() disconnects the underlying stream
617 from the buffer or text IO and returns it.
618
Mark Dickinson33841c32009-05-01 15:37:04 +0000619- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
620 floats with absolute value over 1e50. Also remove length
621 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
622 12.34 no longer raise an exception.

Mark Dickinsone6a076d2009-04-18 11:48:33 +0000645- Issue #1869 (and many duplicates): make round(x, n) correctly
646 rounded for a float x, by using the decimal <-> binary conversions
647 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
648 consistently agrees with format(x, '.2f').
649
Benjamin Petersonae937c02009-04-18 20:54:08 +0000650- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

654
Eric Smith35e84722009-04-16 20:21:28 +0000655- Issue #5515: str.format() type 'n' combined with commas and leading
656 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000657
658- Implement PEP 378, Format Specifier for Thousands Separator, for
659 floats.
660
Mark Dickinson3370cce2009-04-17 22:40:53 +0000661- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000662 1e11, not 1e12. This avoids printing 13 significant digits in
663 situations where only 12 of them are correct. Example problem
664 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
665 long time.)
666
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000667- Issue #1580: On most platforms, use a 'short' float repr: for a
668 finite float x, repr(x) now outputs a string based on the shortest
669 sequence of decimal digits that rounds to x. Previous behaviour was
670 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000671 Another minor difference is that the new repr switches to
672 exponential notation at 1e16 instead of the previous 1e17; this
673 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000674
675 There's a new sys attribute sys.float_repr_style, which takes
676 the value 'short' to indicate that we're using short float repr,
677 and 'legacy' if the short float repr isn't available for one
678 reason or another.
679
680 The float repr change involves incorporating David Gay's 'perfect
681 rounding' code into the Python core (it's in Python/dtoa.c). As a
682 secondary consequence, all string-to-float and float-to-string
683 conversions (including all float formatting operations) will be
684 correctly rounded on these platforms.
685
686 See issue 1580 discussions for details of platforms for which
687 this change does not apply.
688
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000689- Issue #5759: float() didn't call __float__ on str subclasses.
690
Georg Brandlabc38772009-04-12 15:51:51 +0000691- The string.maketrans() function is deprecated; there is a new static method
692 maketrans() on the bytes and bytearray classes. This removes confusion about
693 the types string.maketrans() is supposed to work with, and mirrors the
694 methods available on the str class.

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

932
Lars Gustäbel42e00912009-03-22 20:34:29 +0000933- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
934 forever on incomplete input. That caused tarfile.open() to hang when used
935 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
936 partial bzip2 compressed data.
937
Mark Dickinson79f52032009-03-17 23:12:51 +0000938- Issue #2110: Add support for thousands separator and 'n' type

984 rotating the object pointer by 4 bits to the right.
985
Mark Dickinson87ec0852009-02-09 17:15:59 +0000986- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
987 it now forces its argument to double before testing for infinity.
988
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000989- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +0000998
Georg Brandl1cdd83c2009-04-05 20:24:29 +0000999- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001000 were suppressing all exceptions. These include list() and bytearray().
1001
Mark Dickinson1124e712009-01-28 21:25:58 +00001002- Issue #4707: round(x, n) now returns an integer if x is an integer.
1003 Previously it returned a float.
1004
Antoine Pitroub52ec782009-01-25 16:34:23 +00001005- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1006 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1007 evaluation loop is compiled with a new dispatch mechanism which gives
1008 speedups of up to 20%, depending on the system, on various benchmarks.
1009
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001010- Issue #4874: Most builtin decoders now reject unicode input.

1016
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001017- Issue #4838: When a module is deallocated, free the memory backing the
1018 optional module state data.
1019
Mark Dickinson8055afd2009-01-17 10:04:45 +00001020- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1021 type to (void *).
1022
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001023- Issue #4935: The overflow checking code in the expandtabs() method common
1024 to str, bytes and bytearray could be optimized away by the compiler, letting
1025 the interpreter segfault instead of raising an error.
1026
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001027- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1028 __next__ method.
1029
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001030- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1031 function no longer attempt to call the __long__ slot to convert an object
1032 to an integer. Only the __int__ and __trunc__ slots are examined.
1033
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001034- Issue #4893: Use NT threading on CE.
1035
Martin v. Löwisec59d042009-01-12 07:59:10 +00001036- Issue #4915: Port sysmodule to Windows CE.
1037
Antoine Pitrouab868312009-01-10 15:40:25 +00001038- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1039 common cases are optimized thanks to a dedicated fast path and a moderate
1040 amount of loop unrolling.
1041
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001042- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1043 collecting the oldest generation) so that allocating lots of objects without
1044 destroying them does not show quadratic performance. Based on a proposal by
1045 Martin von Löwis at
1046 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1047
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001048- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001049 having been closed (for instance, a read() call could return some
1050 previously buffered data). Patch by Dmitry Vasiliev.
1051
Antoine Pitrou05608432009-01-09 18:53:14 +00001052- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1053 flag to work properly. Furthermore, when specifying -u, the text stdout
1054 and stderr streams have line-by-line buffering enabled (the default being
1055 to buffer arbitrary chunks of data).
1056
Raymond Hettinger35631532009-01-09 03:58:09 +00001057- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1058 instead of ints (reducing its size from 4 to 8 times thereby reducing
1059 Python's overall memory).
1060
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001061- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1062 an existing .py counterpart, override the co_filename attributes of all
1063 code objects if the original filename is obsolete (which can happen if the
1064 file has been renamed, moved, or if it is accessed through different paths).
1065 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1066
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001067- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1068 one byte. Also fixes the meaning of len() so that it returns the number of
1069 items, rather than the size in bytes.
1070
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001071- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1072
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001073- Issue #4747: When the terminal does not use utf-8, executing a script with
1074 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1075
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001076- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001077 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001078
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001079- Issue #3680: Reference cycles created through a dict, set or deque iterator
1080 did not get collected.
1081
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001082- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1083 where the tp_hash and tp_dict slots are both NULL.
1084
Georg Brandlccc47b62008-12-28 11:44:14 +00001085- Issue #4759: None is now allowed as the first argument of
1086 bytearray.translate(). It was always allowed for bytes.translate().
1087
Skip Montanaro80072cb2008-12-23 03:51:14 +00001088- Added test case to ensure attempts to read from a file opened for writing
1089 fail.
1090
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001091- Issue #3106: Speedup some comparisons (str/str and int/int).

1094 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1095
Antoine Pitrou621601a2008-12-17 23:18:19 +00001096- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1097 print elapsed times, not only when some objects are uncollectable /
1098 unreachable. Original patch by Neil Schemenauer.
1099
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001100- Issue #3439: Add a bit_length method to int.
1101
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001102- Issue #2173: When getting device encoding, check that return value of
1103 nl_langinfo is not the empty string. This was causing silent build
1104 failures on OS X.
1105
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001106- Issue #4597: Fixed several opcodes that weren't always propagating
1107 exceptions.
1108
1109- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001110 context manager returns a value that cannot be converted to a bool.
1111
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001112- Issue #4445: Replace "sizeof(PyBytesObject)" with
1113 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1114 bytes instances. On a typical machine this saves 3 bytes of memory
1115 (on average) per allocation of a bytes instance.
1116
Christian Heimesa872de52008-12-05 08:26:55 +00001117- Issue #4533: File read operation was dreadfully slow due to a slowly
1118 growing read buffer. Fixed by using the same growth rate algorithm as
1119 Python 2.x.
1120
Antoine Pitrou5504e892008-12-06 21:27:53 +00001121- Issue #4509: Various issues surrounding resize of bytearray objects to
1122 which there are buffer exports (e.g. memoryview instances).
1123
Georg Brandlf9734072008-12-07 15:30:06 +00001124- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1125 method on file objects with closefd=False. The file descriptor is still
1126 kept open but the file object behaves like a closed file. The ``FileIO``
1127 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001128
Antoine Pitroubc420402008-12-07 20:14:49 +00001129- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1135
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001136- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1137 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1138 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1139 of using the replace error handler in PyUnicode_DecodeUTF8().
