Benjamin Peterson46ea4f72009-06-27 21:40:27 +00007What's New in Python 3.2 Alpha 1?
8=================================

10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000015- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
16 could crash in many places because of the PyByteArray_AS_STRING() macro
17 returning NULL. The macro now returns a statically allocated empty
18 string instead.
19
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000020- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
21 where the right hand operand is a set of constants, by turning the set into
22 a frozenset and pre-building it as a constant. The comparison operation
23 is made against the constant instead of building a new set each time it is
24 executed (a similar optimization already existed which turned a list of
25 constants into a pre-built tuple). Patch and additional tests by Dave
26 Malcolm.
27
Antoine Pitrouf2c54842010-01-13 08:07:53 +000028- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
29 methods of bytes, bytearray and unicode objects by using a common
30 implementation based on stringlib's fast search. Patch by Florent Xicluna.
31
Mark Dickinson45b63652010-01-16 18:10:25 +000032- Issue #7632: Fix various str -> float conversion bugs present in 2.7
33 alpha 2, including: (1) a serious 'wrong output' bug that could
34 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
35 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000036 strings corresponding to subnormal values, (3) a memory leak for
37 some values large enough to cause overflow, and (4) a number of
38 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000039
Benjamin Petersonaea44282010-01-04 01:10:28 +000040- The __complex__ method is now looked up on the class of instances to make it
41 consistent with other special methods.
42
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000043- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
44 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
45
Benjamin Petersond12362a2009-12-30 19:44:54 +000046- Issue #7604: Deleting an unset slotted attribute did not raise an
47 AttributeError.
48
Mark Dickinson9ab44b52009-12-30 16:22:49 +000049- Issue #7534: Fix handling of IEEE specials (infinities, nans,
50 negative zero) in ** operator. The behaviour now conforms to that
51 described in C99 Annex F.
52
Mark Dickinsoncbb62742009-12-27 15:09:50 +000053- Issue #1811: improve accuracy and cross-platform consistency for
54 true division of integers: the result of a/b is now correctly
55 rounded for ints a and b (at least on IEEE 754 platforms), and in
56 particular does not depend on the internal representation of an int.
57
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000058- Issue #6834: replace the implementation for the 'python' and 'pythonw'
59 executables on OSX.
60
61 These executables now work properly with the arch(1) command:
62 ``arch -ppc python`` will start a universal binary version of python
63 in PPC mode (unlike previous releases).
64
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000065- Issue #7466: segmentation fault when the garbage collector is called
66 in the middle of populating a tuple. Patch by Florent Xicluna.
67
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +000068- Issue #7419: setlocale() could crash the interpreter on Windows when called
69 with invalid values.
70
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +000071- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
72 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
73
Ronald Oussoren3c1928a2009-11-19 17:15:31 +000074- Issue #7085: Fix crash when importing some extensions in a thread
75 on MacOSX 10.6.
76
Philip Jenvey1309adb2009-11-17 03:43:14 +000077- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
78
Mark Dickinson6f1d0492009-11-15 13:58:49 +000079- Issue #6970: Remove redundant calls when comparing objects that don't
80 implement the relevant rich comparison methods.
81
Mark Dickinsond550c9a2009-11-15 09:57:26 +000082- Issue #7298: fixes for range and reversed(range(...)). Iteration
83 over range(a, b, c) incorrectly gave an empty iterator when a, b and
84 c fit in C long but the length of the range did not. Also fix
85 several cases where reversed(range(a, b, c)) gave wrong results, and
86 fix a refleak for reversed(range(a, b, c)) with large arguments.
87
Raymond Hettingerfc438512009-11-01 20:55:33 +000088- Issue #7244: itertools.izip_longest() no longer ignores exceptions
89 raised during the formation of an output tuple.
90

95
Mark Dickinson27a87a22009-10-25 20:43:34 +000096- Issue #1087418: Boost performance of bitwise operations for longs.
97
Antoine Pitroub6ef9632009-10-24 20:47:05 +000098- Support for AtheOS has been completely removed from the code base. It was
99 disabled since Python 3.0.
100
101- Support for several legacy threading libraries has been disabled. These
102 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
103 will be entirely removed in 3.3.
104

380 to execute file paths that refer to source or compiled Python files as well
381 as zipfiles, directories and other valid sys.path entries that contain a

417 reading from stdin so that existing input does not confuse it and

Antoine Pitroue4501852009-05-14 18:55:55 +0000942- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
943 library. This means, for example, that opening an UTF-16 text file in
944 append mode doesn't add a BOM at the end of the file if the file isn't
945 empty.
946
R. David Murray74b89242009-05-13 17:33:03 +0000947- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
948 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
949 corrects a pydoc regression.
950
R. David Murray99352742009-05-07 18:24:38 +0000951- Issue 5955: aifc's close method did not close the file it wrapped,
952 now it does. This also means getfp method now returns the real fp.

995Core and Builtins
996-----------------
997
Mark Dickinson865e01a2009-05-07 16:37:01 +0000998- Issue #5914: Add new C API function PyOS_string_to_double, and
999 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1000
Eric Smith741191f2009-05-06 13:08:15 +00001001- Issue #3382: float.__format__, complex.__format__, and %-formatting
1002 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1003 affects nan -> NAN and inf -> INF.
1004
Mark Hammond5a607a32009-05-06 08:04:54 +00001005- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1006 in all operations, including splitdrive, split, etc. splitunc() now issues
1007 a PendingDeprecation warning.
1008
Eric Smith63376222009-05-05 14:04:18 +00001009- Issue #5920: For float.__format__, change the behavior with the
1010 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1011 to be like 'g' but with at least one decimal point and with a
1012 default precision of 12. Previously, the behavior the same but with
1013 a default precision of 6. This more closely matches str(), and
1014 reduces surprises when adding alignment flags to the empty
1015 presentation type. This also affects the new complex.__format__ in
1016 the same way.
1017
Martin v. Löwis011e8422009-05-05 04:43:17 +00001018- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1019
R. David Murrayb18500d2009-05-04 22:59:07 +00001020- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1021 shadowed by classtype's, even if it was None. property now
1022 inserts the __doc__ into the subclass instance __dict__.
1023
Antoine Pitrou244651a2009-05-04 18:56:13 +00001024- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1025 sequences. Patch by Nick Barnes and Victor Stinner.
1026
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001027- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001028
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001029- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1030 received a new method, detach(). detach() disconnects the underlying stream
1031 from the buffer or text IO and returns it.
1032
Mark Dickinson33841c32009-05-01 15:37:04 +00001033- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1034 floats with absolute value over 1e50. Also remove length
1035 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1036 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001037
Eric Smith741191f2009-05-06 13:08:15 +00001038- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001039 format(complex(1, 2./3), '.5') now produces a sensible result.
1040
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001041- Issue #5864: Fix empty format code formatting for floats so that it
1042 never gives more than the requested number of significant digits.
1043
Eric Smith6dc46f52009-04-27 20:39:49 +00001044- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1045 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1046
Eric Smithcc32a112009-04-26 21:35:14 +00001047- Issue #5835: Deprecate PyOS_ascii_formatd.
1048
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001049- Issue #4971: Fix titlecase for characters that are their own
1050 titlecase, but not their own uppercase.
1051
Benjamin Peterson193152c2009-04-25 01:08:45 +00001052- Issue #5283: Setting __class__ in __del__ caused a segfault.
1053
Mark Dickinsonad476da2009-04-23 19:14:16 +00001054- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1055 z involves nans, infs or negative zeros.
1056
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001057- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001058
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001059- Issue #1869 (and many duplicates): make round(x, n) correctly
1060 rounded for a float x, by using the decimal <-> binary conversions
1061 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1062 consistently agrees with format(x, '.2f').
1063
Benjamin Petersonae937c02009-04-18 20:54:08 +00001064- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1065 some builtin types.
1066
Eric Smith0923d1d2009-04-16 20:16:10 +00001067- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1068
Eric Smith35e84722009-04-16 20:21:28 +00001069- Issue #5515: str.format() type 'n' combined with commas and leading
1070 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001071
1072- Implement PEP 378, Format Specifier for Thousands Separator, for
1073 floats.
1074
Mark Dickinson3370cce2009-04-17 22:40:53 +00001075- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001076 1e11, not 1e12. This avoids printing 13 significant digits in
1077 situations where only 12 of them are correct. Example problem
1078 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1079 long time.)
1080
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001081- Issue #1580: On most platforms, use a 'short' float repr: for a
1082 finite float x, repr(x) now outputs a string based on the shortest
1083 sequence of decimal digits that rounds to x. Previous behaviour was
1084 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001085 Another minor difference is that the new repr switches to
1086 exponential notation at 1e16 instead of the previous 1e17; this
1087 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001088
1089 There's a new sys attribute sys.float_repr_style, which takes
1090 the value 'short' to indicate that we're using short float repr,
1091 and 'legacy' if the short float repr isn't available for one
1092 reason or another.
1093
1094 The float repr change involves incorporating David Gay's 'perfect
1095 rounding' code into the Python core (it's in Python/dtoa.c). As a
1096 secondary consequence, all string-to-float and float-to-string
1097 conversions (including all float formatting operations) will be
1098 correctly rounded on these platforms.
1099
1100 See issue 1580 discussions for details of platforms for which
1101 this change does not apply.
1102
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001103- Issue #5759: float() didn't call __float__ on str subclasses.
1104
Georg Brandlabc38772009-04-12 15:51:51 +00001105- The string.maketrans() function is deprecated; there is a new static method
1106 maketrans() on the bytes and bytearray classes. This removes confusion about
1107 the types string.maketrans() is supposed to work with, and mirrors the
1108 methods available on the str class.
1109
R. David Murraydc6da8a2009-04-09 22:16:43 +00001110- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1111 its clarity and its speed.
1112
Matthias Klose091c7b12009-04-07 13:24:27 +00001113- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1114 to avoid compiler warnings.
1115
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001116- Issue #3739: The unicode-internal encoder now reports the number of characters
1117 consumed like any other encoder (instead of the number of bytes).

1253
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001254- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1255 byte, and the 'C' code only accepts a unicode character.
1256
Georg Brandl406b3d82009-04-11 21:24:37 +00001257- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1258 when hitting the recursion limit under certain circumstances.
1259
Brett Cannon0759dd62009-04-01 18:13:07 +00001260- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1261
Georg Brandlab6f2f62009-03-31 04:16:10 +00001262- Fix a segfault when running test_exceptions with coverage, caused by
1263 insufficient checks in accessors of Exception.__context__.
1264
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001265- Issue #5604: non-ASCII characters in module name passed to
1266 imp.find_module() were converted to UTF-8 while the path is
1267 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00001269- Issue #5126: str.isprintable() returned False for space characters.
1270
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001271- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1272 the end sys.path, for compatibility with the system install of Python.
1273
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001274- Issue #4688: Add a heuristic so that tuples and dicts containing only
1275 untrackable objects are not tracked by the garbage collector. This can
1276 reduce the size of collections and therefore the garbage collection overhead
1277 on long-running programs, depending on their particular use of datatypes.
1278
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001279- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1291 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1292 and sizeof(Py_UNICODE) == 2.
1293
Eric Smith8ec90442009-03-14 12:29:34 +00001294- Issue #5237: Allow auto-numbered fields in str.format(). For

1296
Antoine Pitrou652e7072009-03-13 19:25:20 +00001297- Issue #5392: when a very low recursion limit was set, the interpreter would
1298 abort with a fatal error after the recursion limit was hit twice.
1299
Matthias Klose042f1332009-04-04 14:32:42 +00001300- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1310 error substitutions from non-strict codec error callbacks in
1311 incrementalencoder and StreamWriter.
1312
Georg Brandl33c28812009-04-01 23:07:29 +00001313- Issue #5656: Fix the coverage reporting when running the test suite with

1342 (typically /dev/zero under Unix) could crash the interpreter.
1343
Benjamin Peterson59406a92009-03-26 17:10:29 +00001344- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1345 io.BufferedRandom have been deprecated for removal in Python 3.2.
1346
Lars Gustäbel42e00912009-03-22 20:34:29 +00001347- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1348 forever on incomplete input. That caused tarfile.open() to hang when used
1349 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1350 partial bzip2 compressed data.
1351
Mark Dickinson79f52032009-03-17 23:12:51 +00001352- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinson87ec0852009-02-09 17:15:59 +00001400- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1401 it now forces its argument to double before testing for infinity.
1402
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001403- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1404 returns a non-number type.

1420 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1421 evaluation loop is compiled with a new dispatch mechanism which gives
1422 speedups of up to 20%, depending on the system, on various benchmarks.

1435 type to (void *).
1436
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001437- Issue #4935: The overflow checking code in the expandtabs() method common
1438 to str, bytes and bytearray could be optimized away by the compiler, letting
1439 the interpreter segfault instead of raising an error.
1440
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001441- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1460 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1461

Antoine Pitrou8043cf82009-01-09 19:54:29 +00001463 having been closed (for instance, a read() call could return some
1464 previously buffered data). Patch by Dmitry Vasiliev.
1465
Antoine Pitrou05608432009-01-09 18:53:14 +00001466- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1467 flag to work properly. Furthermore, when specifying -u, the text stdout
1468 and stderr streams have line-by-line buffering enabled (the default being
1469 to buffer arbitrary chunks of data).
1470
Raymond Hettinger35631532009-01-09 03:58:09 +00001471- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1472 instead of ints (reducing its size from 4 to 8 times thereby reducing
1473 Python's overall memory).
1474
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001475- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1476 an existing .py counterpart, override the co_filename attributes of all
1477 code objects if the original filename is obsolete (which can happen if the
1478 file has been renamed, moved, or if it is accessed through different paths).
1479 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1480
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001481- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1482 one byte. Also fixes the meaning of len() so that it returns the number of
1483 items, rather than the size in bytes.
1484
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001485- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1486
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001487- Issue #4747: When the terminal does not use utf-8, executing a script with

1495
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001496- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1497 where the tp_hash and tp_dict slots are both NULL.
1498
Georg Brandlccc47b62008-12-28 11:44:14 +00001499- Issue #4759: None is now allowed as the first argument of

1551 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1552 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1553 of using the replace error handler in PyUnicode_DecodeUTF8().

1874 do an explicit seek to the end of file (so that e.g. tell() returns the
