Mark Dickinsonb6447512009-11-15 10:17:48 +000015- Issue #7298: fixes for range and reversed(range(...)). Iteration
16 over range(a, b, c) incorrectly gave an empty iterator when a, b and
17 c fit in C long but the length of the range did not. Also fix
18 several cases where reversed(range(a, b, c)) gave wrong results, and
19 fix a refleak for reversed(range(a, b, c)) with large arguments.

Antoine Pitrou4def5152009-11-13 22:39:40 +000049- Issue #7318: multiprocessing now uses a timeout when it fails to establish
50 a connection with another process, rather than looping endlessly. The
51 default timeout is 20 seconds, which should be amply sufficient for
52 local connections.
53
Antoine Pitrou959f3e52009-11-09 16:52:46 +000054- Issue #7282: Fix a memory leak when an RLock was used in a thread other

71 reading from stdin so that existing input does not confuse it and
72 lead to incorrect entry or an IOError. It also properly flushes it
73 afterwards to avoid the terminal echoing the input afterwards on
74 OSes such as Solaris.
75
Mark Dickinson9050bb22009-10-29 12:25:07 +000076- Issue #7233: Fix a number of two-argument Decimal methods to make

Eric Smith741191f2009-05-06 13:08:15 +0000593- Issue #3382: float.__format__, complex.__format__, and %-formatting
594 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
595 affects nan -> NAN and inf -> INF.
596
Mark Hammond5a607a32009-05-06 08:04:54 +0000597- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
598 in all operations, including splitdrive, split, etc. splitunc() now issues
599 a PendingDeprecation warning.
600
Eric Smith63376222009-05-05 14:04:18 +0000601- Issue #5920: For float.__format__, change the behavior with the
602 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
603 to be like 'g' but with at least one decimal point and with a
604 default precision of 12. Previously, the behavior the same but with
605 a default precision of 6. This more closely matches str(), and
606 reduces surprises when adding alignment flags to the empty
607 presentation type. This also affects the new complex.__format__ in
608 the same way.
609
Martin v. Löwis011e8422009-05-05 04:43:17 +0000610- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
611
R. David Murrayb18500d2009-05-04 22:59:07 +0000612- Issue #5890: in subclasses of 'property' the __doc__ attribute was
613 shadowed by classtype's, even if it was None. property now
614 inserts the __doc__ into the subclass instance __dict__.
615
Antoine Pitrou244651a2009-05-04 18:56:13 +0000616- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

618
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000619- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000620
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000621- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
622 received a new method, detach(). detach() disconnects the underlying stream
623 from the buffer or text IO and returns it.
624
Mark Dickinson33841c32009-05-01 15:37:04 +0000625- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
626 floats with absolute value over 1e50. Also remove length
627 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
628 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000629
Eric Smith741191f2009-05-06 13:08:15 +0000630- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000631 format(complex(1, 2./3), '.5') now produces a sensible result.
632
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000633- Issue #5864: Fix empty format code formatting for floats so that it
634 never gives more than the requested number of significant digits.
635
Eric Smith6dc46f52009-04-27 20:39:49 +0000636- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

642 titlecase, but not their own uppercase.
643
Benjamin Peterson193152c2009-04-25 01:08:45 +0000644- Issue #5283: Setting __class__ in __del__ caused a segfault.
645
Mark Dickinsonad476da2009-04-23 19:14:16 +0000646- Issue #5816: complex(repr(z)) now recovers z exactly, even when
647 z involves nans, infs or negative zeros.
648
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000649- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000650
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000651- Issue #1869 (and many duplicates): make round(x, n) correctly
652 rounded for a float x, by using the decimal <-> binary conversions
653 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
654 consistently agrees with format(x, '.2f').
655
Benjamin Petersonae937c02009-04-18 20:54:08 +0000656- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
657 some builtin types.
658
Eric Smith0923d1d2009-04-16 20:16:10 +0000659- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
660
Eric Smith35e84722009-04-16 20:21:28 +0000661- Issue #5515: str.format() type 'n' combined with commas and leading
662 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000663
664- Implement PEP 378, Format Specifier for Thousands Separator, for
665 floats.
666
Mark Dickinson3370cce2009-04-17 22:40:53 +0000667- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000668 1e11, not 1e12. This avoids printing 13 significant digits in
669 situations where only 12 of them are correct. Example problem
670 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
671 long time.)
672
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000673- Issue #1580: On most platforms, use a 'short' float repr: for a
674 finite float x, repr(x) now outputs a string based on the shortest
675 sequence of decimal digits that rounds to x. Previous behaviour was
676 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000677 Another minor difference is that the new repr switches to
678 exponential notation at 1e16 instead of the previous 1e17; this
679 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000680
681 There's a new sys attribute sys.float_repr_style, which takes
682 the value 'short' to indicate that we're using short float repr,
683 and 'legacy' if the short float repr isn't available for one
684 reason or another.
685
686 The float repr change involves incorporating David Gay's 'perfect
687 rounding' code into the Python core (it's in Python/dtoa.c). As a
688 secondary consequence, all string-to-float and float-to-string
689 conversions (including all float formatting operations) will be
690 correctly rounded on these platforms.
691
692 See issue 1580 discussions for details of platforms for which
693 this change does not apply.
694
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000695- Issue #5759: float() didn't call __float__ on str subclasses.
696
Georg Brandlabc38772009-04-12 15:51:51 +0000697- The string.maketrans() function is deprecated; there is a new static method
698 maketrans() on the bytes and bytearray classes. This removes confusion about
699 the types string.maketrans() is supposed to work with, and mirrors the
700 methods available on the str class.
701
R. David Murraydc6da8a2009-04-09 22:16:43 +0000702- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

706 to avoid compiler warnings.
707
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000708- Issue #3739: The unicode-internal encoder now reports the number of characters

865
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000866- Issue #4688: Add a heuristic so that tuples and dicts containing only
867 untrackable objects are not tracked by the garbage collector. This can
868 reduce the size of collections and therefore the garbage collection overhead
869 on long-running programs, depending on their particular use of datatypes.

990 rotating the object pointer by 4 bits to the right.
991
Mark Dickinson87ec0852009-02-09 17:15:59 +0000992- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
993 it now forces its argument to double before testing for infinity.
994
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +0000995- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001004
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001005- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001006 were suppressing all exceptions. These include list() and bytearray().

1009 Previously it returned a float.
1010
Antoine Pitroub52ec782009-01-25 16:34:23 +00001011- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1012 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1013 evaluation loop is compiled with a new dispatch mechanism which gives
1014 speedups of up to 20%, depending on the system, on various benchmarks.
1015

1022
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001023- Issue #4838: When a module is deallocated, free the memory backing the
1024 optional module state data.
1025
Mark Dickinson8055afd2009-01-17 10:04:45 +00001026- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1027 type to (void *).
1028
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001029- Issue #4935: The overflow checking code in the expandtabs() method common
1030 to str, bytes and bytearray could be optimized away by the compiler, letting
1031 the interpreter segfault instead of raising an error.
1032
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001033- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1034 __next__ method.
1035
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001036- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1037 function no longer attempt to call the __long__ slot to convert an object
1038 to an integer. Only the __int__ and __trunc__ slots are examined.
1039
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001040- Issue #4893: Use NT threading on CE.
1041
Martin v. Löwisec59d042009-01-12 07:59:10 +00001042- Issue #4915: Port sysmodule to Windows CE.
1043
Antoine Pitrouab868312009-01-10 15:40:25 +00001044- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1045 common cases are optimized thanks to a dedicated fast path and a moderate
1046 amount of loop unrolling.
1047
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001048- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1049 collecting the oldest generation) so that allocating lots of objects without
1050 destroying them does not show quadratic performance. Based on a proposal by
1051 Martin von Löwis at
1052 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1053
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001054- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001055 having been closed (for instance, a read() call could return some
1056 previously buffered data). Patch by Dmitry Vasiliev.
1057
Antoine Pitrou05608432009-01-09 18:53:14 +00001058- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1059 flag to work properly. Furthermore, when specifying -u, the text stdout
1060 and stderr streams have line-by-line buffering enabled (the default being
1061 to buffer arbitrary chunks of data).
1062
Raymond Hettinger35631532009-01-09 03:58:09 +00001063- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1064 instead of ints (reducing its size from 4 to 8 times thereby reducing
1065 Python's overall memory).
1066
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001067- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1068 an existing .py counterpart, override the co_filename attributes of all
1069 code objects if the original filename is obsolete (which can happen if the
1070 file has been renamed, moved, or if it is accessed through different paths).
1071 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1072
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001073- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1074 one byte. Also fixes the meaning of len() so that it returns the number of
1075 items, rather than the size in bytes.
1076
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001077- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1078
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001079- Issue #4747: When the terminal does not use utf-8, executing a script with
1080 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1081
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001082- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001083 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001084
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001085- Issue #3680: Reference cycles created through a dict, set or deque iterator
1086 did not get collected.
1087
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001088- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1089 where the tp_hash and tp_dict slots are both NULL.
1090
Georg Brandlccc47b62008-12-28 11:44:14 +00001091- Issue #4759: None is now allowed as the first argument of
1092 bytearray.translate(). It was always allowed for bytes.translate().
1093
Skip Montanaro80072cb2008-12-23 03:51:14 +00001094- Added test case to ensure attempts to read from a file opened for writing
1095 fail.
1096
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001097- Issue #3106: Speedup some comparisons (str/str and int/int).

1100 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1101
Antoine Pitrou621601a2008-12-17 23:18:19 +00001102- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1103 print elapsed times, not only when some objects are uncollectable /
1104 unreachable. Original patch by Neil Schemenauer.
1105
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001106- Issue #3439: Add a bit_length method to int.
1107
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001108- Issue #2173: When getting device encoding, check that return value of
1109 nl_langinfo is not the empty string. This was causing silent build
1110 failures on OS X.
1111
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001112- Issue #4597: Fixed several opcodes that weren't always propagating
1113 exceptions.
1114
1115- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001116 context manager returns a value that cannot be converted to a bool.
1117
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001118- Issue #4445: Replace "sizeof(PyBytesObject)" with
1119 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1120 bytes instances. On a typical machine this saves 3 bytes of memory
1121 (on average) per allocation of a bytes instance.
1122
Christian Heimesa872de52008-12-05 08:26:55 +00001123- Issue #4533: File read operation was dreadfully slow due to a slowly
1124 growing read buffer. Fixed by using the same growth rate algorithm as
1125 Python 2.x.
1126
Antoine Pitrou5504e892008-12-06 21:27:53 +00001127- Issue #4509: Various issues surrounding resize of bytearray objects to
1128 which there are buffer exports (e.g. memoryview instances).
1129
Georg Brandlf9734072008-12-07 15:30:06 +00001130- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1131 method on file objects with closefd=False. The file descriptor is still
1132 kept open but the file object behaves like a closed file. The ``FileIO``
1133 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001134
Antoine Pitroubc420402008-12-07 20:14:49 +00001135- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1141
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001142- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1143 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1144 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1145 of using the replace error handler in PyUnicode_DecodeUTF8().
