Benjamin Petersonbd35b032009-04-04 23:16:41 +0000628What's New in Python 3.1 beta 1?
629================================
630
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +0000631*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +0000632
633Core and Builtins
634-----------------
635
Mark Dickinson865e01a2009-05-07 16:37:01 +0000636- Issue #5914: Add new C API function PyOS_string_to_double, and
637 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
638
Eric Smith741191f2009-05-06 13:08:15 +0000639- Issue #3382: float.__format__, complex.__format__, and %-formatting
640 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
641 affects nan -> NAN and inf -> INF.
642
Mark Hammond5a607a32009-05-06 08:04:54 +0000643- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
644 in all operations, including splitdrive, split, etc. splitunc() now issues
645 a PendingDeprecation warning.
646
Eric Smith63376222009-05-05 14:04:18 +0000647- Issue #5920: For float.__format__, change the behavior with the
648 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
649 to be like 'g' but with at least one decimal point and with a
650 default precision of 12. Previously, the behavior the same but with
651 a default precision of 6. This more closely matches str(), and
652 reduces surprises when adding alignment flags to the empty
653 presentation type. This also affects the new complex.__format__ in
654 the same way.
655
Martin v. Löwis011e8422009-05-05 04:43:17 +0000656- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
657
R. David Murrayb18500d2009-05-04 22:59:07 +0000658- Issue #5890: in subclasses of 'property' the __doc__ attribute was
659 shadowed by classtype's, even if it was None. property now
660 inserts the __doc__ into the subclass instance __dict__.
661
Antoine Pitrou244651a2009-05-04 18:56:13 +0000662- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
663 sequences. Patch by Nick Barnes and Victor Stinner.
664
Martin v. Löwise0a2b722009-05-10 08:08:56 +0000665- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +0000666
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000667- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
668 received a new method, detach(). detach() disconnects the underlying stream
669 from the buffer or text IO and returns it.
670
Mark Dickinson33841c32009-05-01 15:37:04 +0000671- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
672 floats with absolute value over 1e50. Also remove length
673 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
674 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000675
Eric Smith741191f2009-05-06 13:08:15 +0000676- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000677 format(complex(1, 2./3), '.5') now produces a sensible result.
678
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000679- Issue #5864: Fix empty format code formatting for floats so that it
680 never gives more than the requested number of significant digits.
681
Eric Smith6dc46f52009-04-27 20:39:49 +0000682- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
683 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
684
Eric Smithcc32a112009-04-26 21:35:14 +0000685- Issue #5835: Deprecate PyOS_ascii_formatd.
686
Martin v. Löwis71efeb72009-04-26 01:02:07 +0000687- Issue #4971: Fix titlecase for characters that are their own
688 titlecase, but not their own uppercase.
689
Benjamin Peterson193152c2009-04-25 01:08:45 +0000690- Issue #5283: Setting __class__ in __del__ caused a segfault.
691
Mark Dickinsonad476da2009-04-23 19:14:16 +0000692- Issue #5816: complex(repr(z)) now recovers z exactly, even when
693 z involves nans, infs or negative zeros.
694
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000695- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000696
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000697- Issue #1869 (and many duplicates): make round(x, n) correctly
698 rounded for a float x, by using the decimal <-> binary conversions
699 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
700 consistently agrees with format(x, '.2f').
701
Benjamin Petersonae937c02009-04-18 20:54:08 +0000702- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
703 some builtin types.
704
Eric Smith0923d1d2009-04-16 20:16:10 +0000705- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
706
Eric Smith35e84722009-04-16 20:21:28 +0000707- Issue #5515: str.format() type 'n' combined with commas and leading
708 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000709
710- Implement PEP 378, Format Specifier for Thousands Separator, for
711 floats.
712
Mark Dickinson3370cce2009-04-17 22:40:53 +0000713- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000714 1e11, not 1e12. This avoids printing 13 significant digits in
715 situations where only 12 of them are correct. Example problem
716 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
717 long time.)
718
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000719- Issue #1580: On most platforms, use a 'short' float repr: for a
720 finite float x, repr(x) now outputs a string based on the shortest
721 sequence of decimal digits that rounds to x. Previous behaviour was
722 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000723 Another minor difference is that the new repr switches to
724 exponential notation at 1e16 instead of the previous 1e17; this
725 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000726
727 There's a new sys attribute sys.float_repr_style, which takes
728 the value 'short' to indicate that we're using short float repr,
729 and 'legacy' if the short float repr isn't available for one
730 reason or another.
731
732 The float repr change involves incorporating David Gay's 'perfect
733 rounding' code into the Python core (it's in Python/dtoa.c). As a
734 secondary consequence, all string-to-float and float-to-string
735 conversions (including all float formatting operations) will be
736 correctly rounded on these platforms.
737
738 See issue 1580 discussions for details of platforms for which
739 this change does not apply.
740
Benjamin Peterson2808d3c2009-04-15 21:34:27 +0000741- Issue #5759: float() didn't call __float__ on str subclasses.
742
Georg Brandlabc38772009-04-12 15:51:51 +0000743- The string.maketrans() function is deprecated; there is a new static method
744 maketrans() on the bytes and bytearray classes. This removes confusion about
745 the types string.maketrans() is supposed to work with, and mirrors the
746 methods available on the str class.
747
R. David Murraydc6da8a2009-04-09 22:16:43 +0000748- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
749 its clarity and its speed.
750
Matthias Klose091c7b12009-04-07 13:24:27 +0000751- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
752 to avoid compiler warnings.
753
Walter Dörwald8dc33d52009-05-06 14:41:26 +0000754- Issue #3739: The unicode-internal encoder now reports the number of characters
755 consumed like any other encoder (instead of the number of bytes).
756

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

924 --enable-big-digits option to configure, which overrides the
925 default. Add sys.int_info structseq to provide information about
926 the internal format.

Mark Dickinson87ec0852009-02-09 17:15:59 +00001038- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1039 it now forces its argument to double before testing for infinity.
1040
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001041- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001050
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001051- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001052 were suppressing all exceptions. These include list() and bytearray().
1053
Mark Dickinson1124e712009-01-28 21:25:58 +00001054- Issue #4707: round(x, n) now returns an integer if x is an integer.
1055 Previously it returned a float.
1056
Antoine Pitroub52ec782009-01-25 16:34:23 +00001057- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1058 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1059 evaluation loop is compiled with a new dispatch mechanism which gives
1060 speedups of up to 20%, depending on the system, on various benchmarks.
1061

1070 optional module state data.
1071
Mark Dickinson8055afd2009-01-17 10:04:45 +00001072- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1073 type to (void *).
1074
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001075- Issue #4935: The overflow checking code in the expandtabs() method common
1076 to str, bytes and bytearray could be optimized away by the compiler, letting
1077 the interpreter segfault instead of raising an error.
1078
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001079- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1080 __next__ method.
1081
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001082- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1083 function no longer attempt to call the __long__ slot to convert an object
1084 to an integer. Only the __int__ and __trunc__ slots are examined.
1085
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001086- Issue #4893: Use NT threading on CE.

1089
Antoine Pitrouab868312009-01-10 15:40:25 +00001090- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1091 common cases are optimized thanks to a dedicated fast path and a moderate
1092 amount of loop unrolling.
1093
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001094- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1095 collecting the oldest generation) so that allocating lots of objects without
1096 destroying them does not show quadratic performance. Based on a proposal by
1097 Martin von Löwis at
1098 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1099
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001100- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001101 having been closed (for instance, a read() call could return some
1102 previously buffered data). Patch by Dmitry Vasiliev.
1103
Antoine Pitrou05608432009-01-09 18:53:14 +00001104- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1105 flag to work properly. Furthermore, when specifying -u, the text stdout
1106 and stderr streams have line-by-line buffering enabled (the default being
1107 to buffer arbitrary chunks of data).
1108
Raymond Hettinger35631532009-01-09 03:58:09 +00001109- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1110 instead of ints (reducing its size from 4 to 8 times thereby reducing
1111 Python's overall memory).
1112
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001113- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1114 an existing .py counterpart, override the co_filename attributes of all
1115 code objects if the original filename is obsolete (which can happen if the
1116 file has been renamed, moved, or if it is accessed through different paths).
1117 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1118
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001119- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1120 one byte. Also fixes the meaning of len() so that it returns the number of
1121 items, rather than the size in bytes.
1122
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001123- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1124
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001125- Issue #4747: When the terminal does not use utf-8, executing a script with
1126 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1127
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001128- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001129 file with `bytes' filename on Windows.

Antoine Pitrou7ddda782009-01-01 15:35:33 +00001131- Issue #3680: Reference cycles created through a dict, set or deque iterator
1132 did not get collected.
1133
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001134- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1135 where the tp_hash and tp_dict slots are both NULL.
1136
Georg Brandlccc47b62008-12-28 11:44:14 +00001137- Issue #4759: None is now allowed as the first argument of
1138 bytearray.translate(). It was always allowed for bytes.translate().
1139
Skip Montanaro80072cb2008-12-23 03:51:14 +00001140- Added test case to ensure attempts to read from a file opened for writing
1141 fail.

1153
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001154- Issue #2173: When getting device encoding, check that return value of
1155 nl_langinfo is not the empty string. This was causing silent build
1156 failures on OS X.
1157
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001158- Issue #4597: Fixed several opcodes that weren't always propagating
1159 exceptions.

1161- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001162 context manager returns a value that cannot be converted to a bool.
1163
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001164- Issue #4445: Replace "sizeof(PyBytesObject)" with
1165 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1166 bytes instances. On a typical machine this saves 3 bytes of memory
1167 (on average) per allocation of a bytes instance.
1168
Christian Heimesa872de52008-12-05 08:26:55 +00001169- Issue #4533: File read operation was dreadfully slow due to a slowly
1170 growing read buffer. Fixed by using the same growth rate algorithm as
1171 Python 2.x.
1172
Antoine Pitrou5504e892008-12-06 21:27:53 +00001173- Issue #4509: Various issues surrounding resize of bytearray objects to
1174 which there are buffer exports (e.g. memoryview instances).
1175
Georg Brandlf9734072008-12-07 15:30:06 +00001176- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1177 method on file objects with closefd=False. The file descriptor is still
1178 kept open but the file object behaves like a closed file. The ``FileIO``
1179 object also got a new readonly attribute ``closefd``.

1189 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1190 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1191 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00001796- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
1797 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
1798 the same behaviour as test_ttkguionly (and now also test_tk) which is to
1799 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00001801- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00001802 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00001803 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00001805- Issue #5083: New 'gui' resource for regrtest.
