618
619- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
620 tests on darwin even when the OS was installed on a case-sensitive
621 filesystem. Also fixed tests that should not be run when
622 sys.dont_write_bytecode is true.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000625What's New in Python 3.1 beta 1?
626================================
627
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000628*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000629
630Core and Builtins
631-----------------
632
Mark Dickinson865e01a2009-05-07 16:37:01 +0000633- Issue #5914: Add new C API function PyOS_string_to_double, and
634 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
635
Eric Smith741191f2009-05-06 13:08:15 +0000636- Issue #3382: float.__format__, complex.__format__, and %-formatting
637 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
638 affects nan -> NAN and inf -> INF.
639
Mark Hammond5a607a32009-05-06 08:04:54 +0000640- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
641 in all operations, including splitdrive, split, etc. splitunc() now issues
642 a PendingDeprecation warning.
643
Eric Smith63376222009-05-05 14:04:18 +0000644- Issue #5920: For float.__format__, change the behavior with the
645 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
646 to be like 'g' but with at least one decimal point and with a
647 default precision of 12. Previously, the behavior the same but with
648 a default precision of 6. This more closely matches str(), and
649 reduces surprises when adding alignment flags to the empty
650 presentation type. This also affects the new complex.__format__ in
651 the same way.
652
Martin v. Löwis011e8422009-05-05 04:43:17 +0000653- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
654
R. David Murrayb18500d2009-05-04 22:59:07 +0000655- Issue #5890: in subclasses of 'property' the __doc__ attribute was
656 shadowed by classtype's, even if it was None. property now
657 inserts the __doc__ into the subclass instance __dict__.
658
Antoine Pitrou244651a2009-05-04 18:56:13 +0000659- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
660 sequences. Patch by Nick Barnes and Victor Stinner.
661
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000662- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000663
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000664- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
665 received a new method, detach(). detach() disconnects the underlying stream
666 from the buffer or text IO and returns it.
667
Mark Dickinson33841c32009-05-01 15:37:04 +0000668- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
669 floats with absolute value over 1e50. Also remove length
670 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
671 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000672
Eric Smith741191f2009-05-06 13:08:15 +0000673- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000674 format(complex(1, 2./3), '.5') now produces a sensible result.
675
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000676- Issue #5864: Fix empty format code formatting for floats so that it
677 never gives more than the requested number of significant digits.
678
Eric Smith6dc46f52009-04-27 20:39:49 +0000679- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
680 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
681
Eric Smithcc32a112009-04-26 21:35:14 +0000682- Issue #5835: Deprecate PyOS_ascii_formatd.
683
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000684- Issue #4971: Fix titlecase for characters that are their own
685 titlecase, but not their own uppercase.
686
Benjamin Peterson193152c2009-04-25 01:08:45 +0000687- Issue #5283: Setting __class__ in __del__ caused a segfault.
688
Mark Dickinsonad476da2009-04-23 19:14:16 +0000689- Issue #5816: complex(repr(z)) now recovers z exactly, even when
690 z involves nans, infs or negative zeros.
691
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000692- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000693
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000694- Issue #1869 (and many duplicates): make round(x, n) correctly
695 rounded for a float x, by using the decimal <-> binary conversions
696 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
697 consistently agrees with format(x, '.2f').
698
Benjamin Petersonae937c02009-04-18 20:54:08 +0000699- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
700 some builtin types.
701
Eric Smith0923d1d2009-04-16 20:16:10 +0000702- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
703
Eric Smith35e84722009-04-16 20:21:28 +0000704- Issue #5515: str.format() type 'n' combined with commas and leading
705 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000706
707- Implement PEP 378, Format Specifier for Thousands Separator, for
708 floats.
709
Mark Dickinson3370cce2009-04-17 22:40:53 +0000710- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000711 1e11, not 1e12. This avoids printing 13 significant digits in
712 situations where only 12 of them are correct. Example problem
713 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
714 long time.)
715
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000716- Issue #1580: On most platforms, use a 'short' float repr: for a
717 finite float x, repr(x) now outputs a string based on the shortest
718 sequence of decimal digits that rounds to x. Previous behaviour was
719 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000720 Another minor difference is that the new repr switches to
721 exponential notation at 1e16 instead of the previous 1e17; this
722 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000723
724 There's a new sys attribute sys.float_repr_style, which takes
725 the value 'short' to indicate that we're using short float repr,
726 and 'legacy' if the short float repr isn't available for one
727 reason or another.
728
729 The float repr change involves incorporating David Gay's 'perfect
730 rounding' code into the Python core (it's in Python/dtoa.c). As a
731 secondary consequence, all string-to-float and float-to-string
732 conversions (including all float formatting operations) will be
733 correctly rounded on these platforms.
734
735 See issue 1580 discussions for details of platforms for which
736 this change does not apply.
737
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000738- Issue #5759: float() didn't call __float__ on str subclasses.
739
Georg Brandlabc38772009-04-12 15:51:51 +0000740- The string.maketrans() function is deprecated; there is a new static method
741 maketrans() on the bytes and bytearray classes. This removes confusion about
742 the types string.maketrans() is supposed to work with, and mirrors the
743 methods available on the str class.
744
R. David Murraydc6da8a2009-04-09 22:16:43 +0000745- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
746 its clarity and its speed.
747
Matthias Klose091c7b12009-04-07 13:24:27 +0000748- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
749 to avoid compiler warnings.
750
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000751- Issue #3739: The unicode-internal encoder now reports the number of characters
752 consumed like any other encoder (instead of the number of bytes).
753

Antoine Pitrou3a652b12009-03-23 18:52:06 +0000909- Issue #4688: Add a heuristic so that tuples and dicts containing only
910 untrackable objects are not tracked by the garbage collector. This can
911 reduce the size of collections and therefore the garbage collection overhead
912 on long-running programs, depending on their particular use of datatypes.

1033 rotating the object pointer by 4 bits to the right.
1034
Mark Dickinson87ec0852009-02-09 17:15:59 +00001035- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1036 it now forces its argument to double before testing for infinity.
1037
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001038- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001047
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001048- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001049 were suppressing all exceptions. These include list() and bytearray().
1050
Mark Dickinson1124e712009-01-28 21:25:58 +00001051- Issue #4707: round(x, n) now returns an integer if x is an integer.
1052 Previously it returned a float.
1053
Antoine Pitroub52ec782009-01-25 16:34:23 +00001054- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1055 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1056 evaluation loop is compiled with a new dispatch mechanism which gives
1057 speedups of up to 20%, depending on the system, on various benchmarks.
1058
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001059- Issue #4874: Most builtin decoders now reject unicode input.

1065
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001066- Issue #4838: When a module is deallocated, free the memory backing the
1067 optional module state data.
1068
Mark Dickinson8055afd2009-01-17 10:04:45 +00001069- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1070 type to (void *).
1071
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001072- Issue #4935: The overflow checking code in the expandtabs() method common
1073 to str, bytes and bytearray could be optimized away by the compiler, letting
1074 the interpreter segfault instead of raising an error.
1075
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001076- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1077 __next__ method.
1078
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001079- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1080 function no longer attempt to call the __long__ slot to convert an object
1081 to an integer. Only the __int__ and __trunc__ slots are examined.
1082
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001083- Issue #4893: Use NT threading on CE.
1084

1086
Antoine Pitrouab868312009-01-10 15:40:25 +00001087- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1088 common cases are optimized thanks to a dedicated fast path and a moderate
1089 amount of loop unrolling.
1090
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001091- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1092 collecting the oldest generation) so that allocating lots of objects without
1093 destroying them does not show quadratic performance. Based on a proposal by
1094 Martin von Löwis at
1095 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1096
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001097- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001098 having been closed (for instance, a read() call could return some
1099 previously buffered data). Patch by Dmitry Vasiliev.
1100
Antoine Pitrou05608432009-01-09 18:53:14 +00001101- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1102 flag to work properly. Furthermore, when specifying -u, the text stdout
1103 and stderr streams have line-by-line buffering enabled (the default being
1104 to buffer arbitrary chunks of data).
1105
Raymond Hettinger35631532009-01-09 03:58:09 +00001106- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1107 instead of ints (reducing its size from 4 to 8 times thereby reducing
1108 Python's overall memory).
1109
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001110- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1111 an existing .py counterpart, override the co_filename attributes of all
1112 code objects if the original filename is obsolete (which can happen if the
1113 file has been renamed, moved, or if it is accessed through different paths).
1114 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1115
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001116- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1117 one byte. Also fixes the meaning of len() so that it returns the number of
1118 items, rather than the size in bytes.
1119
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001120- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1121
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001122- Issue #4747: When the terminal does not use utf-8, executing a script with
1123 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1124
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001125- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001126 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001127
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001128- Issue #3680: Reference cycles created through a dict, set or deque iterator
1129 did not get collected.
1130
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001131- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1132 where the tp_hash and tp_dict slots are both NULL.
1133
Georg Brandlccc47b62008-12-28 11:44:14 +00001134- Issue #4759: None is now allowed as the first argument of
1135 bytearray.translate(). It was always allowed for bytes.translate().
1136
Skip Montanaro80072cb2008-12-23 03:51:14 +00001137- Added test case to ensure attempts to read from a file opened for writing
1138 fail.
1139
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001140- Issue #3106: Speedup some comparisons (str/str and int/int).

1143 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1144
Antoine Pitrou621601a2008-12-17 23:18:19 +00001145- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1146 print elapsed times, not only when some objects are uncollectable /
1147 unreachable. Original patch by Neil Schemenauer.
1148
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001149- Issue #3439: Add a bit_length method to int.
1150
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001151- Issue #2173: When getting device encoding, check that return value of
1152 nl_langinfo is not the empty string. This was causing silent build
1153 failures on OS X.
1154
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001155- Issue #4597: Fixed several opcodes that weren't always propagating
1156 exceptions.
1157
1158- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001159 context manager returns a value that cannot be converted to a bool.
1160
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001161- Issue #4445: Replace "sizeof(PyBytesObject)" with
1162 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1163 bytes instances. On a typical machine this saves 3 bytes of memory
1164 (on average) per allocation of a bytes instance.
1165
Christian Heimesa872de52008-12-05 08:26:55 +00001166- Issue #4533: File read operation was dreadfully slow due to a slowly
1167 growing read buffer. Fixed by using the same growth rate algorithm as
1168 Python 2.x.
1169
Antoine Pitrou5504e892008-12-06 21:27:53 +00001170- Issue #4509: Various issues surrounding resize of bytearray objects to
1171 which there are buffer exports (e.g. memoryview instances).
1172
Georg Brandlf9734072008-12-07 15:30:06 +00001173- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1174 method on file objects with closefd=False. The file descriptor is still
1175 kept open but the file object behaves like a closed file. The ``FileIO``
1176 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001177
Antoine Pitroubc420402008-12-07 20:14:49 +00001178- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001185- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1186 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1187 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1188 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00001790- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
1791 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00001793- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
1794 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1795 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1796 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00001798- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00001799 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00001800 from test support, which does the conversion.
