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

Benjamin Peterson05159c42009-12-03 03:01:27 +0000224- Issue #2422: When compiled with the ``--with-valgrind`` option, the
225 pymalloc allocator will be automatically disabled when running under
226 Valgrind. This gives improved memory leak detection when running
227 under Valgrind, while taking advantage of pymalloc at other times.

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

927
Antoine Pitroue4501852009-05-14 18:55:55 +0000928- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
929 library. This means, for example, that opening an UTF-16 text file in
930 append mode doesn't add a BOM at the end of the file if the file isn't
931 empty.
932
R. David Murray74b89242009-05-13 17:33:03 +0000933- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
934 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
935 corrects a pydoc regression.
936
R. David Murray99352742009-05-07 18:24:38 +0000937- Issue 5955: aifc's close method did not close the file it wrapped,
938 now it does. This also means getfp method now returns the real fp.

981Core and Builtins
982-----------------
983
Mark Dickinson865e01a2009-05-07 16:37:01 +0000984- Issue #5914: Add new C API function PyOS_string_to_double, and
985 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
986
Eric Smith741191f2009-05-06 13:08:15 +0000987- Issue #3382: float.__format__, complex.__format__, and %-formatting
988 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
989 affects nan -> NAN and inf -> INF.
990
Mark Hammond5a607a32009-05-06 08:04:54 +0000991- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
992 in all operations, including splitdrive, split, etc. splitunc() now issues
993 a PendingDeprecation warning.
994
Eric Smith63376222009-05-05 14:04:18 +0000995- Issue #5920: For float.__format__, change the behavior with the
996 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
997 to be like 'g' but with at least one decimal point and with a
998 default precision of 12. Previously, the behavior the same but with
999 a default precision of 6. This more closely matches str(), and
1000 reduces surprises when adding alignment flags to the empty
1001 presentation type. This also affects the new complex.__format__ in
1002 the same way.
1003
Martin v. Löwis011e8422009-05-05 04:43:17 +00001004- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1005
R. David Murrayb18500d2009-05-04 22:59:07 +00001006- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1007 shadowed by classtype's, even if it was None. property now
1008 inserts the __doc__ into the subclass instance __dict__.
1009
Antoine Pitrou244651a2009-05-04 18:56:13 +00001010- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1011 sequences. Patch by Nick Barnes and Victor Stinner.
1012
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001013- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001014
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001015- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1016 received a new method, detach(). detach() disconnects the underlying stream
1017 from the buffer or text IO and returns it.
1018
Mark Dickinson33841c32009-05-01 15:37:04 +00001019- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1020 floats with absolute value over 1e50. Also remove length
1021 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1022 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001023
Eric Smith741191f2009-05-06 13:08:15 +00001024- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001025 format(complex(1, 2./3), '.5') now produces a sensible result.
1026
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001027- Issue #5864: Fix empty format code formatting for floats so that it
1028 never gives more than the requested number of significant digits.
1029
Eric Smith6dc46f52009-04-27 20:39:49 +00001030- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1031 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1032
Eric Smithcc32a112009-04-26 21:35:14 +00001033- Issue #5835: Deprecate PyOS_ascii_formatd.
1034
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001035- Issue #4971: Fix titlecase for characters that are their own
1036 titlecase, but not their own uppercase.
1037
Benjamin Peterson193152c2009-04-25 01:08:45 +00001038- Issue #5283: Setting __class__ in __del__ caused a segfault.
1039
Mark Dickinsonad476da2009-04-23 19:14:16 +00001040- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1041 z involves nans, infs or negative zeros.
1042
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001043- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001044
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001045- Issue #1869 (and many duplicates): make round(x, n) correctly
1046 rounded for a float x, by using the decimal <-> binary conversions
1047 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1048 consistently agrees with format(x, '.2f').
1049
Benjamin Petersonae937c02009-04-18 20:54:08 +00001050- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1051 some builtin types.
1052
Eric Smith0923d1d2009-04-16 20:16:10 +00001053- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1054
Eric Smith35e84722009-04-16 20:21:28 +00001055- Issue #5515: str.format() type 'n' combined with commas and leading
1056 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001057
1058- Implement PEP 378, Format Specifier for Thousands Separator, for
1059 floats.
1060
Mark Dickinson3370cce2009-04-17 22:40:53 +00001061- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001062 1e11, not 1e12. This avoids printing 13 significant digits in
1063 situations where only 12 of them are correct. Example problem
1064 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1065 long time.)
1066
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001067- Issue #1580: On most platforms, use a 'short' float repr: for a
1068 finite float x, repr(x) now outputs a string based on the shortest
1069 sequence of decimal digits that rounds to x. Previous behaviour was
1070 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001071 Another minor difference is that the new repr switches to
1072 exponential notation at 1e16 instead of the previous 1e17; this
1073 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001074
1075 There's a new sys attribute sys.float_repr_style, which takes
1076 the value 'short' to indicate that we're using short float repr,
1077 and 'legacy' if the short float repr isn't available for one
1078 reason or another.
1079
1080 The float repr change involves incorporating David Gay's 'perfect
1081 rounding' code into the Python core (it's in Python/dtoa.c). As a
1082 secondary consequence, all string-to-float and float-to-string
1083 conversions (including all float formatting operations) will be
1084 correctly rounded on these platforms.
1085
1086 See issue 1580 discussions for details of platforms for which
1087 this change does not apply.
1088
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001089- Issue #5759: float() didn't call __float__ on str subclasses.
1090
Georg Brandlabc38772009-04-12 15:51:51 +00001091- The string.maketrans() function is deprecated; there is a new static method
1092 maketrans() on the bytes and bytearray classes. This removes confusion about
1093 the types string.maketrans() is supposed to work with, and mirrors the
1094 methods available on the str class.
1095
R. David Murraydc6da8a2009-04-09 22:16:43 +00001096- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1097 its clarity and its speed.
1098
Matthias Klose091c7b12009-04-07 13:24:27 +00001099- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1100 to avoid compiler warnings.
1101
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001102- Issue #3739: The unicode-internal encoder now reports the number of characters
1103 consumed like any other encoder (instead of the number of bytes).

1239
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001240- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1241 byte, and the 'C' code only accepts a unicode character.
1242
Georg Brandl406b3d82009-04-11 21:24:37 +00001243- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1244 when hitting the recursion limit under certain circumstances.
1245
Brett Cannon0759dd62009-04-01 18:13:07 +00001246- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1247
Georg Brandlab6f2f62009-03-31 04:16:10 +00001248- Fix a segfault when running test_exceptions with coverage, caused by
1249 insufficient checks in accessors of Exception.__context__.
1250
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001251- Issue #5604: non-ASCII characters in module name passed to
1252 imp.find_module() were converted to UTF-8 while the path is
1253 converted to the default filesystem encoding, causing nonsense.
1254
Benjamin Peterson09832742009-03-26 17:15:46 +00001255- Issue #5126: str.isprintable() returned False for space characters.
1256
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001257- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1258 the end sys.path, for compatibility with the system install of Python.
1259
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001260- Issue #4688: Add a heuristic so that tuples and dicts containing only
1261 untrackable objects are not tracked by the garbage collector. This can
1262 reduce the size of collections and therefore the garbage collection overhead
1263 on long-running programs, depending on their particular use of datatypes.
1264
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001265- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1270 2**15 for the internal representation of integers, for performance
1271 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1272 --enable-big-digits option to configure, which overrides the
1273 default. Add sys.int_info structseq to provide information about
1274 the internal format.
1275
Mark Dickinson081dfee2009-03-18 14:47:41 +00001276- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1277 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1278 and sizeof(Py_UNICODE) == 2.
1279
Eric Smith8ec90442009-03-14 12:29:34 +00001280- Issue #5237: Allow auto-numbered fields in str.format(). For

1282
Antoine Pitrou652e7072009-03-13 19:25:20 +00001283- Issue #5392: when a very low recursion limit was set, the interpreter would
1284 abort with a fatal error after the recursion limit was hit twice.
1285
Matthias Klose042f1332009-04-04 14:32:42 +00001286- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
1287 short file names.

Hye-Shik Chang944820b2009-04-02 10:33:16 +00001295- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
1296 error substitutions from non-strict codec error callbacks in
1297 incrementalencoder and StreamWriter.
1298
Georg Brandl33c28812009-04-01 23:07:29 +00001299- Issue #5656: Fix the coverage reporting when running the test suite with

1317
Brett Cannon7f6b4f82009-03-30 21:30:26 +00001318- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1319 bytes already but the failure was non-obvious.
1320
Jesse Noller7af4ef82009-03-30 16:47:15 +00001321- Issue #5177: Multiprocessing's SocketListener class now uses

1328 (typically /dev/zero under Unix) could crash the interpreter.
1329
Benjamin Peterson59406a92009-03-26 17:10:29 +00001330- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1331 io.BufferedRandom have been deprecated for removal in Python 3.2.
1332
Lars Gustäbel42e00912009-03-22 20:34:29 +00001333- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1334 forever on incomplete input. That caused tarfile.open() to hang when used
1335 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1336 partial bzip2 compressed data.
1337
Mark Dickinson79f52032009-03-17 23:12:51 +00001338- Issue #2110: Add support for thousands separator and 'n' type

1343
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00001344- The error detection code in FileIO.close() could fail to reflect the `errno`
1345 value, and report it as -1 instead.

1356 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001357 struct.error instead of returning b'\xff\xff\xff\xff'. The
1358 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1359 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00001386- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1387 it now forces its argument to double before testing for infinity.
1388
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001389- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001398
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001399- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001400 were suppressing all exceptions. These include list() and bytearray().
1401
Mark Dickinson1124e712009-01-28 21:25:58 +00001402- Issue #4707: round(x, n) now returns an integer if x is an integer.

1406 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1407 evaluation loop is compiled with a new dispatch mechanism which gives
1408 speedups of up to 20%, depending on the system, on various benchmarks.

1421 type to (void *).
1422
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001423- Issue #4935: The overflow checking code in the expandtabs() method common
1424 to str, bytes and bytearray could be optimized away by the compiler, letting
1425 the interpreter segfault instead of raising an error.
1426
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001427- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1446 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1447

1450 previously buffered data). Patch by Dmitry Vasiliev.
1451
Antoine Pitrou05608432009-01-09 18:53:14 +00001452- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1453 flag to work properly. Furthermore, when specifying -u, the text stdout
1454 and stderr streams have line-by-line buffering enabled (the default being
1455 to buffer arbitrary chunks of data).
1456
Raymond Hettinger35631532009-01-09 03:58:09 +00001457- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1458 instead of ints (reducing its size from 4 to 8 times thereby reducing
1459 Python's overall memory).
1460
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001461- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1462 an existing .py counterpart, override the co_filename attributes of all
1463 code objects if the original filename is obsolete (which can happen if the
1464 file has been renamed, moved, or if it is accessed through different paths).
1465 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1466
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001467- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1468 one byte. Also fixes the meaning of len() so that it returns the number of
1469 items, rather than the size in bytes.
1470
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001471- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1472
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001473- Issue #4747: When the terminal does not use utf-8, executing a script with

1481
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001482- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1483 where the tp_hash and tp_dict slots are both NULL.
1484
Georg Brandlccc47b62008-12-28 11:44:14 +00001485- Issue #4759: None is now allowed as the first argument of

1539 of using the replace error handler in PyUnicode_DecodeUTF8().

2145 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2146 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2147 skip the tests if DISPLAY is defined but can't be used.
2148
R. David Murraya21e4ca2009-03-31 23:16:50 +00002149- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002150 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002151 from test support, which does the conversion.
