Benjamin Peterson46ea4f72009-06-27 21:40:27 +00007What's New in Python 3.2 Alpha 1?
8=================================
9
10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Mark Dickinsonbc099642010-01-29 17:27:24 +000015- Issue #7788: Fix an interpreter crash produced by deleting a list
16 slice with very large step value.
17
Eric Smithf7bb5782010-01-27 00:44:57 +000018- Issue #7766: Change sys.getwindowsversion() return value to a named
19 tuple and add the additional members returned in an OSVERSIONINFOEX
20 structure. The new members are service_pack_major, service_pack_minor,
21 suite_mask, and product_type.
22
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000023- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
24 could crash in many places because of the PyByteArray_AS_STRING() macro
25 returning NULL. The macro now returns a statically allocated empty
26 string instead.
27
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000028- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
29 where the right hand operand is a set of constants, by turning the set into
30 a frozenset and pre-building it as a constant. The comparison operation
31 is made against the constant instead of building a new set each time it is
32 executed (a similar optimization already existed which turned a list of
33 constants into a pre-built tuple). Patch and additional tests by Dave
34 Malcolm.
35
Antoine Pitrouf2c54842010-01-13 08:07:53 +000036- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
37 methods of bytes, bytearray and unicode objects by using a common
38 implementation based on stringlib's fast search. Patch by Florent Xicluna.
39
Mark Dickinson45b63652010-01-16 18:10:25 +000040- Issue #7632: Fix various str -> float conversion bugs present in 2.7
41 alpha 2, including: (1) a serious 'wrong output' bug that could
42 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
43 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000044 strings corresponding to subnormal values, (3) a memory leak for
45 some values large enough to cause overflow, and (4) a number of
46 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000047
Benjamin Petersonaea44282010-01-04 01:10:28 +000048- The __complex__ method is now looked up on the class of instances to make it
49 consistent with other special methods.
50
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000051- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
52 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
53
Benjamin Petersond12362a2009-12-30 19:44:54 +000054- Issue #7604: Deleting an unset slotted attribute did not raise an
55 AttributeError.
56
Mark Dickinson9ab44b52009-12-30 16:22:49 +000057- Issue #7534: Fix handling of IEEE specials (infinities, nans,
58 negative zero) in ** operator. The behaviour now conforms to that
59 described in C99 Annex F.
60
Mark Dickinsoncbb62742009-12-27 15:09:50 +000061- Issue #1811: improve accuracy and cross-platform consistency for
62 true division of integers: the result of a/b is now correctly
63 rounded for ints a and b (at least on IEEE 754 platforms), and in
64 particular does not depend on the internal representation of an int.
65
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000066- Issue #6834: replace the implementation for the 'python' and 'pythonw'
67 executables on OSX.
68
69 These executables now work properly with the arch(1) command:
70 ``arch -ppc python`` will start a universal binary version of python
71 in PPC mode (unlike previous releases).
72
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000073- Issue #7466: segmentation fault when the garbage collector is called
74 in the middle of populating a tuple. Patch by Florent Xicluna.
75
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +000076- Issue #7419: setlocale() could crash the interpreter on Windows when called
77 with invalid values.
78
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +000079- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
80 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
81
Ronald Oussoren3c1928a2009-11-19 17:15:31 +000082- Issue #7085: Fix crash when importing some extensions in a thread
83 on MacOSX 10.6.
84
Philip Jenvey1309adb2009-11-17 03:43:14 +000085- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
86
Mark Dickinson6f1d0492009-11-15 13:58:49 +000087- Issue #6970: Remove redundant calls when comparing objects that don't
88 implement the relevant rich comparison methods.
89
Mark Dickinsond550c9a2009-11-15 09:57:26 +000090- Issue #7298: fixes for range and reversed(range(...)). Iteration
91 over range(a, b, c) incorrectly gave an empty iterator when a, b and
92 c fit in C long but the length of the range did not. Also fix
93 several cases where reversed(range(a, b, c)) gave wrong results, and
94 fix a refleak for reversed(range(a, b, c)) with large arguments.
95
Raymond Hettingerfc438512009-11-01 20:55:33 +000096- Issue #7244: itertools.izip_longest() no longer ignores exceptions
97 raised during the formation of an output tuple.
98

105
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000106- Support for AtheOS has been completely removed from the code base. It was
107 disabled since Python 3.0.
108
109- Support for several legacy threading libraries has been disabled. These
110 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
111 will be entirely removed in 3.3.
112
Raymond Hettingeraf7adad2009-10-22 11:22:50 +0000113- Peephole constant folding had missed UNARY_POSITIVE.

126 There should be no other effect than a small decrease in memory use.
127 Patch by Christopher Tur Lesniewski-Laas.
128
Antoine Pitrou403ce782009-10-14 17:14:16 +0000129- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when
Antoine Pitrou671141d2009-10-19 19:37:25 +0000130 using byte values greater than 127. Patch by Derk Drukker.
Antoine Pitrou403ce782009-10-14 17:14:16 +0000131
Amaury Forgeot d'Arc7d520792009-10-06 21:03:20 +0000132- Issue #1571184: The Unicode database contains properties for more characters.
133 The tables for code points representing numeric values, white spaces or line

233
Benjamin Peterson05159c42009-12-03 03:01:27 +0000234- Issue #2422: When compiled with the ``--with-valgrind`` option, the
235 pymalloc allocator will be automatically disabled when running under
236 Valgrind. This gives improved memory leak detection when running
237 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000410- Issue #6816: runpy now provides a run_path function that allows Python code
411 to execute file paths that refer to source or compiled Python files as well
412 as zipfiles, directories and other valid sys.path entries that contain a
413 __main__.py file. This allows applications that run other Python scripts to
414 support the same flexibility as the CPython command line itself.

429
Antoine Pitroub0872682009-11-09 16:08:16 +0000430- Issue #7282: Fix a memory leak when an RLock was used in a thread other

448 reading from stdin so that existing input does not confuse it and
449 lead to incorrect entry or an IOError. It also properly flushes it
450 afterwards to avoid the terminal echoing the input afterwards on
451 OSes such as Solaris.
452
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000453- Issue #7233: Fix a number of two-argument Decimal methods to make

920 (1) inf and nan strings with trailing whitespace were incorrectly
921 rejected; (2) parsing of strings representing infinities and nans
922 was locale aware; and (3) the interpretation of fromhex('-nan')
923 didn't match that of float('-nan').

1026Core and Builtins
1027-----------------
1028
Mark Dickinson865e01a2009-05-07 16:37:01 +00001029- Issue #5914: Add new C API function PyOS_string_to_double, and
1030 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1031
Eric Smith741191f2009-05-06 13:08:15 +00001032- Issue #3382: float.__format__, complex.__format__, and %-formatting
1033 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1034 affects nan -> NAN and inf -> INF.
1035
Mark Hammond5a607a32009-05-06 08:04:54 +00001036- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1037 in all operations, including splitdrive, split, etc. splitunc() now issues
1038 a PendingDeprecation warning.
1039
Eric Smith63376222009-05-05 14:04:18 +00001040- Issue #5920: For float.__format__, change the behavior with the
1041 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1042 to be like 'g' but with at least one decimal point and with a
1043 default precision of 12. Previously, the behavior the same but with
1044 a default precision of 6. This more closely matches str(), and
1045 reduces surprises when adding alignment flags to the empty
1046 presentation type. This also affects the new complex.__format__ in
1047 the same way.
1048
Martin v. Löwis011e8422009-05-05 04:43:17 +00001049- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1050
R. David Murrayb18500d2009-05-04 22:59:07 +00001051- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1052 shadowed by classtype's, even if it was None. property now
1053 inserts the __doc__ into the subclass instance __dict__.
1054
Antoine Pitrou244651a2009-05-04 18:56:13 +00001055- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1056 sequences. Patch by Nick Barnes and Victor Stinner.
1057
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001058- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001059
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001060- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1061 received a new method, detach(). detach() disconnects the underlying stream
1062 from the buffer or text IO and returns it.
1063
Mark Dickinson33841c32009-05-01 15:37:04 +00001064- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1065 floats with absolute value over 1e50. Also remove length
1066 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1067 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001068
Eric Smith741191f2009-05-06 13:08:15 +00001069- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001070 format(complex(1, 2./3), '.5') now produces a sensible result.
1071
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001072- Issue #5864: Fix empty format code formatting for floats so that it
1073 never gives more than the requested number of significant digits.
1074
Eric Smith6dc46f52009-04-27 20:39:49 +00001075- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1076 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1077
Eric Smithcc32a112009-04-26 21:35:14 +00001078- Issue #5835: Deprecate PyOS_ascii_formatd.
1079
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001080- Issue #4971: Fix titlecase for characters that are their own
1081 titlecase, but not their own uppercase.
1082
Benjamin Peterson193152c2009-04-25 01:08:45 +00001083- Issue #5283: Setting __class__ in __del__ caused a segfault.
1084
Mark Dickinsonad476da2009-04-23 19:14:16 +00001085- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1086 z involves nans, infs or negative zeros.
1087
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001088- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001089
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001090- Issue #1869 (and many duplicates): make round(x, n) correctly
1091 rounded for a float x, by using the decimal <-> binary conversions
1092 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1093 consistently agrees with format(x, '.2f').
1094
Benjamin Petersonae937c02009-04-18 20:54:08 +00001095- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1096 some builtin types.
1097
Eric Smith0923d1d2009-04-16 20:16:10 +00001098- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1099
Eric Smith35e84722009-04-16 20:21:28 +00001100- Issue #5515: str.format() type 'n' combined with commas and leading
1101 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001102
1103- Implement PEP 378, Format Specifier for Thousands Separator, for
1104 floats.
1105
Mark Dickinson3370cce2009-04-17 22:40:53 +00001106- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001107 1e11, not 1e12. This avoids printing 13 significant digits in
1108 situations where only 12 of them are correct. Example problem
1109 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1110 long time.)
1111
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001112- Issue #1580: On most platforms, use a 'short' float repr: for a
1113 finite float x, repr(x) now outputs a string based on the shortest
1114 sequence of decimal digits that rounds to x. Previous behaviour was
1115 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001116 Another minor difference is that the new repr switches to
1117 exponential notation at 1e16 instead of the previous 1e17; this
1118 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001119
1120 There's a new sys attribute sys.float_repr_style, which takes
1121 the value 'short' to indicate that we're using short float repr,
1122 and 'legacy' if the short float repr isn't available for one
1123 reason or another.
1124
1125 The float repr change involves incorporating David Gay's 'perfect
1126 rounding' code into the Python core (it's in Python/dtoa.c). As a
1127 secondary consequence, all string-to-float and float-to-string
1128 conversions (including all float formatting operations) will be
1129 correctly rounded on these platforms.
1130
1131 See issue 1580 discussions for details of platforms for which
1132 this change does not apply.
1133
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001134- Issue #5759: float() didn't call __float__ on str subclasses.
1135
Georg Brandlabc38772009-04-12 15:51:51 +00001136- The string.maketrans() function is deprecated; there is a new static method
1137 maketrans() on the bytes and bytearray classes. This removes confusion about
1138 the types string.maketrans() is supposed to work with, and mirrors the
1139 methods available on the str class.
1140
R. David Murraydc6da8a2009-04-09 22:16:43 +00001141- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1142 its clarity and its speed.
1143
Matthias Klose091c7b12009-04-07 13:24:27 +00001144- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1145 to avoid compiler warnings.
1146
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001147- Issue #3739: The unicode-internal encoder now reports the number of characters
1148 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00001226- Issue #1161031: fix readwrite select flag handling: POLLPRI now
1227 results in a handle_expt_event call, not handle_read_event, and POLLERR
1228 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1229 dispatcher now has an 'ignore_log_types' attribute for suppressing
1230 log messages, which is set to 'warning' by default.

1304
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001305- Issue #4688: Add a heuristic so that tuples and dicts containing only
1306 untrackable objects are not tracked by the garbage collector. This can
1307 reduce the size of collections and therefore the garbage collection overhead
1308 on long-running programs, depending on their particular use of datatypes.

1377
Lars Gustäbel42e00912009-03-22 20:34:29 +00001378- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1379 forever on incomplete input. That caused tarfile.open() to hang when used
1380 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1381 partial bzip2 compressed data.

1498 flag to work properly. Furthermore, when specifying -u, the text stdout
1499 and stderr streams have line-by-line buffering enabled (the default being
1500 to buffer arbitrary chunks of data).
1501
Raymond Hettinger35631532009-01-09 03:58:09 +00001502- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

1905 do an explicit seek to the end of file (so that e.g. tell() returns the
