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

11
12Core and Builtins
13-----------------
14
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000015- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
16 where the right hand operand is a set of constants, by turning the set into
17 a frozenset and pre-building it as a constant. The comparison operation
18 is made against the constant instead of building a new set each time it is
19 executed (a similar optimization already existed which turned a list of
20 constants into a pre-built tuple). Patch and additional tests by Dave
21 Malcolm.
22
Antoine Pitrouf2c54842010-01-13 08:07:53 +000023- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
24 methods of bytes, bytearray and unicode objects by using a common
25 implementation based on stringlib's fast search. Patch by Florent Xicluna.
26
Mark Dickinson45b63652010-01-16 18:10:25 +000027- Issue #7632: Fix various str -> float conversion bugs present in 2.7
28 alpha 2, including: (1) a serious 'wrong output' bug that could
29 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
30 that occurred in debug builds when parsing certain long numeric
31 strings corresponding to subnormal values, and (3) a number of flaws
32 that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000033
Benjamin Petersonaea44282010-01-04 01:10:28 +000034- The __complex__ method is now looked up on the class of instances to make it
35 consistent with other special methods.
36
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000037- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
38 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
39
Benjamin Petersond12362a2009-12-30 19:44:54 +000040- Issue #7604: Deleting an unset slotted attribute did not raise an
41 AttributeError.
42
Mark Dickinson9ab44b52009-12-30 16:22:49 +000043- Issue #7534: Fix handling of IEEE specials (infinities, nans,
44 negative zero) in ** operator. The behaviour now conforms to that
45 described in C99 Annex F.
46
Mark Dickinsoncbb62742009-12-27 15:09:50 +000047- Issue #1811: improve accuracy and cross-platform consistency for
48 true division of integers: the result of a/b is now correctly
49 rounded for ints a and b (at least on IEEE 754 platforms), and in
50 particular does not depend on the internal representation of an int.
51
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000052- Issue #6834: replace the implementation for the 'python' and 'pythonw'
53 executables on OSX.
54
55 These executables now work properly with the arch(1) command:
56 ``arch -ppc python`` will start a universal binary version of python
57 in PPC mode (unlike previous releases).
58
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000059- Issue #7466: segmentation fault when the garbage collector is called
60 in the middle of populating a tuple. Patch by Florent Xicluna.
61
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +000062- Issue #7419: setlocale() could crash the interpreter on Windows when called
63 with invalid values.
64
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +000065- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
66 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
67

74 implement the relevant rich comparison methods.
75
Mark Dickinsond550c9a2009-11-15 09:57:26 +000076- Issue #7298: fixes for range and reversed(range(...)). Iteration
77 over range(a, b, c) incorrectly gave an empty iterator when a, b and
78 c fit in C long but the length of the range did not. Also fix
79 several cases where reversed(range(a, b, c)) gave wrong results, and
80 fix a refleak for reversed(range(a, b, c)) with large arguments.
81
Raymond Hettingerfc438512009-11-01 20:55:33 +000082- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitroue4501852009-05-14 18:55:55 +0000922- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
923 library. This means, for example, that opening an UTF-16 text file in
924 append mode doesn't add a BOM at the end of the file if the file isn't
925 empty.
926
R. David Murray74b89242009-05-13 17:33:03 +0000927- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

929 corrects a pydoc regression.
930
R. David Murray99352742009-05-07 18:24:38 +0000931- Issue 5955: aifc's close method did not close the file it wrapped,
932 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +0000974
975Core and Builtins
976-----------------
977
Mark Dickinson865e01a2009-05-07 16:37:01 +0000978- Issue #5914: Add new C API function PyOS_string_to_double, and
979 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
980
Eric Smith741191f2009-05-06 13:08:15 +0000981- Issue #3382: float.__format__, complex.__format__, and %-formatting
982 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
983 affects nan -> NAN and inf -> INF.
984
Mark Hammond5a607a32009-05-06 08:04:54 +0000985- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
986 in all operations, including splitdrive, split, etc. splitunc() now issues
987 a PendingDeprecation warning.
988
Eric Smith63376222009-05-05 14:04:18 +0000989- Issue #5920: For float.__format__, change the behavior with the
990 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
991 to be like 'g' but with at least one decimal point and with a
992 default precision of 12. Previously, the behavior the same but with
993 a default precision of 6. This more closely matches str(), and
994 reduces surprises when adding alignment flags to the empty
995 presentation type. This also affects the new complex.__format__ in
996 the same way.
997
Martin v. Löwis011e8422009-05-05 04:43:17 +0000998- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
999
R. David Murrayb18500d2009-05-04 22:59:07 +00001000- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1001 shadowed by classtype's, even if it was None. property now
1002 inserts the __doc__ into the subclass instance __dict__.
1003
Antoine Pitrou244651a2009-05-04 18:56:13 +00001004- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1005 sequences. Patch by Nick Barnes and Victor Stinner.
1006
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001007- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001008
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001009- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1010 received a new method, detach(). detach() disconnects the underlying stream
1011 from the buffer or text IO and returns it.
1012
Mark Dickinson33841c32009-05-01 15:37:04 +00001013- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1014 floats with absolute value over 1e50. Also remove length
1015 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1016 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001017
Eric Smith741191f2009-05-06 13:08:15 +00001018- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001019 format(complex(1, 2./3), '.5') now produces a sensible result.
1020
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001021- Issue #5864: Fix empty format code formatting for floats so that it
1022 never gives more than the requested number of significant digits.
1023
Eric Smith6dc46f52009-04-27 20:39:49 +00001024- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1025 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1026
Eric Smithcc32a112009-04-26 21:35:14 +00001027- Issue #5835: Deprecate PyOS_ascii_formatd.
1028
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001029- Issue #4971: Fix titlecase for characters that are their own
1030 titlecase, but not their own uppercase.
1031
Benjamin Peterson193152c2009-04-25 01:08:45 +00001032- Issue #5283: Setting __class__ in __del__ caused a segfault.
1033
Mark Dickinsonad476da2009-04-23 19:14:16 +00001034- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1035 z involves nans, infs or negative zeros.
1036
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001037- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001038
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001039- Issue #1869 (and many duplicates): make round(x, n) correctly
1040 rounded for a float x, by using the decimal <-> binary conversions
1041 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1042 consistently agrees with format(x, '.2f').
1043
Benjamin Petersonae937c02009-04-18 20:54:08 +00001044- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1045 some builtin types.
1046
Eric Smith0923d1d2009-04-16 20:16:10 +00001047- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1048
Eric Smith35e84722009-04-16 20:21:28 +00001049- Issue #5515: str.format() type 'n' combined with commas and leading
1050 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001051
1052- Implement PEP 378, Format Specifier for Thousands Separator, for
1053 floats.
1054
Mark Dickinson3370cce2009-04-17 22:40:53 +00001055- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001056 1e11, not 1e12. This avoids printing 13 significant digits in
1057 situations where only 12 of them are correct. Example problem
1058 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1059 long time.)
1060
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001061- Issue #1580: On most platforms, use a 'short' float repr: for a
1062 finite float x, repr(x) now outputs a string based on the shortest
1063 sequence of decimal digits that rounds to x. Previous behaviour was
1064 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001065 Another minor difference is that the new repr switches to
1066 exponential notation at 1e16 instead of the previous 1e17; this
1067 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001068
1069 There's a new sys attribute sys.float_repr_style, which takes
1070 the value 'short' to indicate that we're using short float repr,
1071 and 'legacy' if the short float repr isn't available for one
1072 reason or another.
1073
1074 The float repr change involves incorporating David Gay's 'perfect
1075 rounding' code into the Python core (it's in Python/dtoa.c). As a
1076 secondary consequence, all string-to-float and float-to-string
1077 conversions (including all float formatting operations) will be
1078 correctly rounded on these platforms.
1079
1080 See issue 1580 discussions for details of platforms for which
1081 this change does not apply.
1082
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001083- Issue #5759: float() didn't call __float__ on str subclasses.
1084
Georg Brandlabc38772009-04-12 15:51:51 +00001085- The string.maketrans() function is deprecated; there is a new static method
1086 maketrans() on the bytes and bytearray classes. This removes confusion about
1087 the types string.maketrans() is supposed to work with, and mirrors the
1088 methods available on the str class.
1089
R. David Murraydc6da8a2009-04-09 22:16:43 +00001090- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1091 its clarity and its speed.
1092
Matthias Klose091c7b12009-04-07 13:24:27 +00001093- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1094 to avoid compiler warnings.
1095
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001096- Issue #3739: The unicode-internal encoder now reports the number of characters
1097 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001232- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1233
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001234- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1235 byte, and the 'C' code only accepts a unicode character.
1236
Georg Brandl406b3d82009-04-11 21:24:37 +00001237- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1238 when hitting the recursion limit under certain circumstances.
1239
Brett Cannon0759dd62009-04-01 18:13:07 +00001240- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1241
Georg Brandlab6f2f62009-03-31 04:16:10 +00001242- Fix a segfault when running test_exceptions with coverage, caused by
1243 insufficient checks in accessors of Exception.__context__.
1244
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001245- Issue #5604: non-ASCII characters in module name passed to
1246 imp.find_module() were converted to UTF-8 while the path is
1247 converted to the default filesystem encoding, causing nonsense.
1248
Benjamin Peterson09832742009-03-26 17:15:46 +00001249- Issue #5126: str.isprintable() returned False for space characters.
1250
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001251- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1252 the end sys.path, for compatibility with the system install of Python.
1253
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001254- Issue #4688: Add a heuristic so that tuples and dicts containing only
1255 untrackable objects are not tracked by the garbage collector. This can
1256 reduce the size of collections and therefore the garbage collection overhead
1257 on long-running programs, depending on their particular use of datatypes.
1258
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001259- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1262
Mark Dickinsonbd792642009-03-18 20:06:12 +00001263- Issue #4258: Make it possible to use base 2**30 instead of base
1264 2**15 for the internal representation of integers, for performance
1265 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1266 --enable-big-digits option to configure, which overrides the
1267 default. Add sys.int_info structseq to provide information about
1268 the internal format.
1269
Mark Dickinson081dfee2009-03-18 14:47:41 +00001270- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1271 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1272 and sizeof(Py_UNICODE) == 2.
1273
Eric Smith8ec90442009-03-14 12:29:34 +00001274- Issue #5237: Allow auto-numbered fields in str.format(). For
1275 example: '{} {}'.format(1, 2) == '1 2'.
1276
Antoine Pitrou652e7072009-03-13 19:25:20 +00001277- Issue #5392: when a very low recursion limit was set, the interpreter would
1278 abort with a fatal error after the recursion limit was hit twice.
1279
Matthias Klose042f1332009-04-04 14:32:42 +00001280- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
1281 short file names.

R. David Murray548ac412009-04-02 19:44:43 +00001287 mailbox.MH.get_message().
1288
Hye-Shik Chang944820b2009-04-02 10:33:16 +00001289- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
1290 error substitutions from non-strict codec error callbacks in
1291 incrementalencoder and StreamWriter.
1292
Georg Brandl33c28812009-04-01 23:07:29 +00001293- Issue #5656: Fix the coverage reporting when running the test suite with

1311
Brett Cannon7f6b4f82009-03-30 21:30:26 +00001312- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1313 bytes already but the failure was non-obvious.
1314
Jesse Noller7af4ef82009-03-30 16:47:15 +00001315- Issue #5177: Multiprocessing's SocketListener class now uses
1316 socket.SO_REUSEADDR on all connections so that the user no longer needs

1322 (typically /dev/zero under Unix) could crash the interpreter.
1323
Benjamin Peterson59406a92009-03-26 17:10:29 +00001324- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1325 io.BufferedRandom have been deprecated for removal in Python 3.2.
1326
Lars Gustäbel42e00912009-03-22 20:34:29 +00001327- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1328 forever on incomplete input. That caused tarfile.open() to hang when used
1329 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1330 partial bzip2 compressed data.
1331
Mark Dickinson79f52032009-03-17 23:12:51 +00001332- Issue #2110: Add support for thousands separator and 'n' type

1337
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00001338- The error detection code in FileIO.close() could fail to reflect the `errno`
1339 value, and report it as -1 instead.

1348
Mark Dickinsonae681df2009-03-21 10:26:31 +00001349- Issue #5463: In struct module, remove deprecated overflow wrapping
1350 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001351 struct.error instead of returning b'\xff\xff\xff\xff'. The
1352 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1353 have been removed from the struct module.

Mark Dickinson87ec0852009-02-09 17:15:59 +00001380- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1381 it now forces its argument to double before testing for infinity.
1382
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001383- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1384 returns a non-number type.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001392
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001393- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001394 were suppressing all exceptions. These include list() and bytearray().
1395
Mark Dickinson1124e712009-01-28 21:25:58 +00001396- Issue #4707: round(x, n) now returns an integer if x is an integer.

1400 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1401 evaluation loop is compiled with a new dispatch mechanism which gives
1402 speedups of up to 20%, depending on the system, on various benchmarks.

1415 type to (void *).
1416
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001417- Issue #4935: The overflow checking code in the expandtabs() method common
1418 to str, bytes and bytearray could be optimized away by the compiler, letting
1419 the interpreter segfault instead of raising an error.
1420
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001421- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1433 common cases are optimized thanks to a dedicated fast path and a moderate
1434 amount of loop unrolling.
1435
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001436- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1437 collecting the oldest generation) so that allocating lots of objects without
1438 destroying them does not show quadratic performance. Based on a proposal by
1439 Martin von Löwis at
1440 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1441
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001442- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001443 having been closed (for instance, a read() call could return some
1444 previously buffered data). Patch by Dmitry Vasiliev.
1445
Antoine Pitrou05608432009-01-09 18:53:14 +00001446- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1447 flag to work properly. Furthermore, when specifying -u, the text stdout
1448 and stderr streams have line-by-line buffering enabled (the default being
1449 to buffer arbitrary chunks of data).
1450
Raymond Hettinger35631532009-01-09 03:58:09 +00001451- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1452 instead of ints (reducing its size from 4 to 8 times thereby reducing
1453 Python's overall memory).
1454
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001455- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1456 an existing .py counterpart, override the co_filename attributes of all
1457 code objects if the original filename is obsolete (which can happen if the
1458 file has been renamed, moved, or if it is accessed through different paths).
1459 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1460
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001461- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1462 one byte. Also fixes the meaning of len() so that it returns the number of
1463 items, rather than the size in bytes.
1464
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001465- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1466
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001467- Issue #4747: When the terminal does not use utf-8, executing a script with
1468 non-ascii characters in its name could fail with a "SyntaxError: None" error.

1474 did not get collected.
1475
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001476- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1477 where the tp_hash and tp_dict slots are both NULL.
1478
Georg Brandlccc47b62008-12-28 11:44:14 +00001479- Issue #4759: None is now allowed as the first argument of
1480 bytearray.translate(). It was always allowed for bytes.translate().
1481
Skip Montanaro80072cb2008-12-23 03:51:14 +00001482- Added test case to ensure attempts to read from a file opened for writing
1483 fail.

1497 nl_langinfo is not the empty string. This was causing silent build
1498 failures on OS X.
1499
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001500- Issue #4597: Fixed several opcodes that weren't always propagating
1501 exceptions.

Antoine Pitrou08838b62009-01-21 00:55:13 +00001853- Issue #5008: When a file is opened in append mode with the new IO library,
1854 do an explicit seek to the end of file (so that e.g. tell() returns the

2139 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2140 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2141 skip the tests if DISPLAY is defined but can't be used.
2142
R. David Murraya21e4ca2009-03-31 23:16:50 +00002143- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002144 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002145 from test support, which does the conversion.
2146
Guilherme Polo9de29af2009-01-28 20:40:48 +00002147- Issue #5083: New 'gui' resource for regrtest.
