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
Eric Smith68af50b2010-02-22 14:58:30 +000015- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
16 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
17 and PyOS_string_to_double instead. See issue #5835 for the original
18 deprecations.
19
Antoine Pitrou05b7c562010-02-02 22:47:00 +000020- Issue #7385: Fix a crash in `MemoryView_FromObject` when
21 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
22
Mark Dickinsonbc099642010-01-29 17:27:24 +000023- Issue #7788: Fix an interpreter crash produced by deleting a list
24 slice with very large step value.
25
Eric Smithf7bb5782010-01-27 00:44:57 +000026- Issue #7766: Change sys.getwindowsversion() return value to a named
27 tuple and add the additional members returned in an OSVERSIONINFOEX
28 structure. The new members are service_pack_major, service_pack_minor,
29 suite_mask, and product_type.
30
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000031- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
32 could crash in many places because of the PyByteArray_AS_STRING() macro
33 returning NULL. The macro now returns a statically allocated empty
34 string instead.
35
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000036- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
37 where the right hand operand is a set of constants, by turning the set into
38 a frozenset and pre-building it as a constant. The comparison operation
39 is made against the constant instead of building a new set each time it is
40 executed (a similar optimization already existed which turned a list of
41 constants into a pre-built tuple). Patch and additional tests by Dave
42 Malcolm.
43
Antoine Pitrouf2c54842010-01-13 08:07:53 +000044- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
45 methods of bytes, bytearray and unicode objects by using a common
46 implementation based on stringlib's fast search. Patch by Florent Xicluna.
47
Mark Dickinson45b63652010-01-16 18:10:25 +000048- Issue #7632: Fix various str -> float conversion bugs present in 2.7
49 alpha 2, including: (1) a serious 'wrong output' bug that could
50 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
51 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000052 strings corresponding to subnormal values, (3) a memory leak for
53 some values large enough to cause overflow, and (4) a number of
54 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000055
Benjamin Petersonaea44282010-01-04 01:10:28 +000056- The __complex__ method is now looked up on the class of instances to make it
57 consistent with other special methods.
58
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000059- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
60 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
61
Benjamin Petersond12362a2009-12-30 19:44:54 +000062- Issue #7604: Deleting an unset slotted attribute did not raise an
63 AttributeError.
64
Mark Dickinson9ab44b52009-12-30 16:22:49 +000065- Issue #7534: Fix handling of IEEE specials (infinities, nans,
66 negative zero) in ** operator. The behaviour now conforms to that
67 described in C99 Annex F.
68
Mark Dickinsoncbb62742009-12-27 15:09:50 +000069- Issue #1811: improve accuracy and cross-platform consistency for
70 true division of integers: the result of a/b is now correctly
71 rounded for ints a and b (at least on IEEE 754 platforms), and in
72 particular does not depend on the internal representation of an int.
73
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000074- Issue #6834: replace the implementation for the 'python' and 'pythonw'
75 executables on OSX.
76
77 These executables now work properly with the arch(1) command:
78 ``arch -ppc python`` will start a universal binary version of python
79 in PPC mode (unlike previous releases).
80
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000081- Issue #7466: segmentation fault when the garbage collector is called
82 in the middle of populating a tuple. Patch by Florent Xicluna.
83
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +000084- Issue #7419: setlocale() could crash the interpreter on Windows when called
85 with invalid values.
86
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +000087- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
88 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
89
Ronald Oussoren3c1928a2009-11-19 17:15:31 +000090- Issue #7085: Fix crash when importing some extensions in a thread
91 on MacOSX 10.6.
92
Philip Jenvey1309adb2009-11-17 03:43:14 +000093- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
94
Mark Dickinson6f1d0492009-11-15 13:58:49 +000095- Issue #6970: Remove redundant calls when comparing objects that don't
96 implement the relevant rich comparison methods.
97
Mark Dickinsond550c9a2009-11-15 09:57:26 +000098- Issue #7298: fixes for range and reversed(range(...)). Iteration
99 over range(a, b, c) incorrectly gave an empty iterator when a, b and
100 c fit in C long but the length of the range did not. Also fix
101 several cases where reversed(range(a, b, c)) gave wrong results, and
102 fix a refleak for reversed(range(a, b, c)) with large arguments.
103
Raymond Hettingerfc438512009-11-01 20:55:33 +0000104- Issue #7244: itertools.izip_longest() no longer ignores exceptions

113
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000114- Support for AtheOS has been completely removed from the code base. It was
115 disabled since Python 3.0.
116
117- Support for several legacy threading libraries has been disabled. These
118 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
119 will be entirely removed in 3.3.
120
Raymond Hettingeraf7adad2009-10-22 11:22:50 +0000121- Peephole constant folding had missed UNARY_POSITIVE.
122
Antoine Pitrou011bd622009-10-20 21:52:47 +0000123- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
124 fixes the problem of some exceptions being thrown at shutdown when the

134 There should be no other effect than a small decrease in memory use.
135 Patch by Christopher Tur Lesniewski-Laas.
136
Antoine Pitrou403ce782009-10-14 17:14:16 +0000137- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when
Antoine Pitrou671141d2009-10-19 19:37:25 +0000138 using byte values greater than 127. Patch by Derk Drukker.
Antoine Pitrou403ce782009-10-14 17:14:16 +0000139
Amaury Forgeot d'Arc7d520792009-10-06 21:03:20 +0000140- Issue #1571184: The Unicode database contains properties for more characters.
141 The tables for code points representing numeric values, white spaces or line
142 breaks are now generated from the official Unicode Character Database files,
143 and include information from the Unihan.txt file.
144
Mark Dickinson2683ab02009-09-29 19:21:35 +0000145- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
146 of producing internally inconsistent Python longs.

Mark Dickinsonde604012010-01-01 19:27:32 +0000209- Issue #5080: The argument parsing functions PyArg_ParseTuple,
210 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
211 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
212 DeprecationWarning for float arguments passed with the 'L' format
213 code. This will become a TypeError in a future version of Python,
214 to match the behaviour of the other integer format codes.
215
Georg Brandl1e28a272009-12-28 08:41:01 +0000216- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

225 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
226 should used for accessing the d_type and d_name members of structures
227 using PyDescr_COMMON.
228
229- Issue #6405: Remove duplicate type declarations in descrobject.h.

240 ``const char *`` as the string is stored beyond the call.
241
Benjamin Peterson05159c42009-12-03 03:01:27 +0000242- Issue #2422: When compiled with the ``--with-valgrind`` option, the
243 pymalloc allocator will be automatically disabled when running under
244 Valgrind. This gives improved memory leak detection when running
245 under Valgrind, while taking advantage of pymalloc at other times.

257
Mark Dickinson84230a12010-02-18 14:49:50 +0000258- Issue #7633: In the decimal module, Context class methods (with the
259 exception of canonical and is_canonical) now accept instances of int
260 and long wherever a Decimal instance is accepted, and implicitly
261 convert that argument to Decimal. Previously only some arguments
262 were converted.
263
R. David Murray1f449142010-02-11 00:15:05 +0000264- Issue #7835: shelve should no longer produce mysterious warnings during
265 interpreter shutdown.

268 in XML processing instructions and comments. These raw characters are
269 allowed by the XML specification, and are necessary when outputting e.g.
270 PHP code in a processing instruction. Patch by Neil Muller.

278
Antoine Pitroub6375f12010-02-04 20:23:24 +0000279- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
280 specified, rather than fall through to AF_PACKET (in the `socket` module).
281 Also, raise ValueError rather than TypeError when an unknown TIPC address
282 type is specified. Patch by Brian Curtin.
283
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000284- Issue #6939: Fix file I/O objects in the `io` module to keep the original
285 file position when calling `truncate()`. It would previously change the
286 file position to the given argument, which goes against the tradition of
287 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
288
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000289- Issue #7610: Reworked implementation of the internal
290 :class:`zipfile.ZipExtFile` class used to represent files stored inside
291 an archive. The new implementation is significantly faster and can
292 be wrapped in a :class:`io.BufferedReader` object for more speedups.
293 It also solves an issue where interleaved calls to `read()` and
294 `readline()` give wrong results. Patch by Nir Aides.

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

461 support the same flexibility as the CPython command line itself.
462

481 recursive locks as fast as regular non-recursive locks (previously,
482 they were slower by 10x to 15x).
483
Antoine Pitroub0872682009-11-09 16:08:16 +0000484- Issue #7282: Fix a memory leak when an RLock was used in a thread other

498 a modification is done through it. This fixes inconsistencies and test
499 failures on systems with slightly bogus mtime behaviour.
500
Gregory P. Smith50467882009-11-01 18:42:17 +0000501- Issue #7246 & Issue #7208: getpass now properly flushes input before
502 reading from stdin so that existing input does not confuse it and
503 lead to incorrect entry or an IOError. It also properly flushes it
504 afterwards to avoid the terminal echoing the input afterwards on
505 OSes such as Solaris.

814 leak-chasing test runs give sensible results. The previous method of
815 reaping threads could return successfully while some Thread objects were
816 still referenced. This also introduces a new private function:
817 :func:`_thread._count()`.

820 longer runs the risk of causing the worker thread to fail.
821
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000822- Issue #7055: test___all__ now greedily detects all modules which have an

Mark Dickinson2e304402009-10-04 18:43:54 +0000829- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
830
Brett Cannon3c273842009-07-20 00:14:29 +0000831- Fixed tests in importlib.test.source.test_abc_loader that were masking

Benjamin Peterson0926ad12009-06-06 18:02:12 +0000918- Issue #6217: The C implementation of io.TextIOWrapper didn't include the
919 errors property. Additionally, the errors and encoding properties of StringIO
920 are always None now.
921
Antoine Pitroud9dfaa92009-06-04 20:32:06 +0000922- Issue #6137: The pickle module now translates module names when loading
923 or dumping pickles with a 2.x-compatible protocol, in order to make data
924 sharing and migration easier. This behaviour can be disabled using the
925 new `fix_imports` optional argument.

971Core and Builtins
972-----------------
973
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000974- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
975 of the command line.
976
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000977- Issue #6012: Add cleanup support to O& argument parsing.

Eric Smith41669ca2009-05-23 14:23:22 +0000979- Issue #6089: Fixed str.format with certain invalid field specifiers
980 that would raise SystemError.
981
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000982- Issue #5982: staticmethod and classmethod now expose the wrapped
983 function with __func__.
984
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000985- Added support for multiple context managers in the same with-statement.
986 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000987
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000988- Issue #5829: complex("1e500") no longer raises OverflowError. This
989 makes it consistent with float("1e500") and interpretation of real
990 and imaginary literals.
991
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000992- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
993
R. David Murraydd226ea2009-05-13 12:27:21 +0000994- Issue #5994: the marshal module now has docstrings.
995
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000996- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
997 (1) inf and nan strings with trailing whitespace were incorrectly
998 rejected; (2) parsing of strings representing infinities and nans
999 was locale aware; and (3) the interpretation of fromhex('-nan')
1000 didn't match that of float('-nan').

1003-------
1004
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001005- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1006
R. David Murrayfb123912009-05-28 18:19:00 +00001007- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1008
R. David Murray1f1b9d32009-05-27 20:56:59 +00001009- Issue #6121: pydoc now ignores leading and trailing spaces in the
1010 argument to the 'help' function.
1011
Georg Brandlfaf41492009-05-26 18:31:11 +00001012- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1013 arguments for strings with a space in them.
1014
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001015- collections.namedtuple() was not working with the following field
1016 names: cls, self, tuple, itemgetter, and property.
1017
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001018- In unittest, using a skipping decorator on a class is now equivalent to
1019 skipping every test on the class. The ClassTestSuite class has been removed.
1020
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001021- Issue #6050: Don't fail extracting a directory from a zipfile if
1022 the directory already exists.
1023
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001024- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1025 than an int, which makes some operations possible under 64-bit Linux (e.g.
1026 DN_MULTISHOT with F_NOTIFY).
1027
Antoine Pitrou716c4442009-05-23 19:04:03 +00001028- Issue #5761: Add the name of the underlying file to the repr() of various
1029 IO objects.
1030
R. David Murraycaa27b72009-05-23 18:49:56 +00001031- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1032 by Musashi Tamura, tests by Marcin Bachry.
1033
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001034- Issue #1983: Fix functions taking or returning a process identifier to use
1035 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1036 a process identifier type wider than the standard C integer type.
1037
R. David Murray87e20742009-05-23 01:30:26 +00001038- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1042 deepcopy()ing.
1043

1049
Antoine Pitroue4501852009-05-14 18:55:55 +00001050- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1051 library. This means, for example, that opening an UTF-16 text file in
1052 append mode doesn't add a BOM at the end of the file if the file isn't
1053 empty.
1054
R. David Murray74b89242009-05-13 17:33:03 +00001055- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1056 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1057 corrects a pydoc regression.
1058
R. David Murray99352742009-05-07 18:24:38 +00001059- Issue 5955: aifc's close method did not close the file it wrapped,
1060 now it does. This also means getfp method now returns the real fp.
1061

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001101*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001102
1103Core and Builtins
1104-----------------
1105
Mark Dickinson865e01a2009-05-07 16:37:01 +00001106- Issue #5914: Add new C API function PyOS_string_to_double, and
1107 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1108
Eric Smith741191f2009-05-06 13:08:15 +00001109- Issue #3382: float.__format__, complex.__format__, and %-formatting
1110 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1111 affects nan -> NAN and inf -> INF.
1112
Mark Hammond5a607a32009-05-06 08:04:54 +00001113- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1114 in all operations, including splitdrive, split, etc. splitunc() now issues
1115 a PendingDeprecation warning.
1116
Eric Smith63376222009-05-05 14:04:18 +00001117- Issue #5920: For float.__format__, change the behavior with the
1118 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1119 to be like 'g' but with at least one decimal point and with a
1120 default precision of 12. Previously, the behavior the same but with
1121 a default precision of 6. This more closely matches str(), and
1122 reduces surprises when adding alignment flags to the empty
1123 presentation type. This also affects the new complex.__format__ in
1124 the same way.
1125
Martin v. Löwis011e8422009-05-05 04:43:17 +00001126- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1127
R. David Murrayb18500d2009-05-04 22:59:07 +00001128- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1129 shadowed by classtype's, even if it was None. property now
1130 inserts the __doc__ into the subclass instance __dict__.
1131
Antoine Pitrou244651a2009-05-04 18:56:13 +00001132- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1133 sequences. Patch by Nick Barnes and Victor Stinner.
1134
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001135- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001136
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001137- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1138 received a new method, detach(). detach() disconnects the underlying stream
1139 from the buffer or text IO and returns it.
1140
Mark Dickinson33841c32009-05-01 15:37:04 +00001141- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1142 floats with absolute value over 1e50. Also remove length
1143 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1144 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001145
Eric Smith741191f2009-05-06 13:08:15 +00001146- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001147 format(complex(1, 2./3), '.5') now produces a sensible result.
1148
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001149- Issue #5864: Fix empty format code formatting for floats so that it
1150 never gives more than the requested number of significant digits.
1151
Eric Smith6dc46f52009-04-27 20:39:49 +00001152- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1153 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1154
Eric Smithcc32a112009-04-26 21:35:14 +00001155- Issue #5835: Deprecate PyOS_ascii_formatd.
1156
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001157- Issue #4971: Fix titlecase for characters that are their own
1158 titlecase, but not their own uppercase.
1159
Benjamin Peterson193152c2009-04-25 01:08:45 +00001160- Issue #5283: Setting __class__ in __del__ caused a segfault.
1161
Mark Dickinsonad476da2009-04-23 19:14:16 +00001162- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1163 z involves nans, infs or negative zeros.
1164
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001165- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001166
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001167- Issue #1869 (and many duplicates): make round(x, n) correctly
1168 rounded for a float x, by using the decimal <-> binary conversions
1169 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1170 consistently agrees with format(x, '.2f').
1171
Benjamin Petersonae937c02009-04-18 20:54:08 +00001172- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1173 some builtin types.
1174
Eric Smith0923d1d2009-04-16 20:16:10 +00001175- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1176
Eric Smith35e84722009-04-16 20:21:28 +00001177- Issue #5515: str.format() type 'n' combined with commas and leading
1178 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001179
1180- Implement PEP 378, Format Specifier for Thousands Separator, for
1181 floats.
1182
Mark Dickinson3370cce2009-04-17 22:40:53 +00001183- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001184 1e11, not 1e12. This avoids printing 13 significant digits in
1185 situations where only 12 of them are correct. Example problem
1186 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1187 long time.)
1188
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001189- Issue #1580: On most platforms, use a 'short' float repr: for a
1190 finite float x, repr(x) now outputs a string based on the shortest
1191 sequence of decimal digits that rounds to x. Previous behaviour was
1192 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001193 Another minor difference is that the new repr switches to
1194 exponential notation at 1e16 instead of the previous 1e17; this
1195 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001196
1197 There's a new sys attribute sys.float_repr_style, which takes
1198 the value 'short' to indicate that we're using short float repr,
1199 and 'legacy' if the short float repr isn't available for one
1200 reason or another.
1201
1202 The float repr change involves incorporating David Gay's 'perfect
1203 rounding' code into the Python core (it's in Python/dtoa.c). As a
1204 secondary consequence, all string-to-float and float-to-string
1205 conversions (including all float formatting operations) will be
1206 correctly rounded on these platforms.
1207
1208 See issue 1580 discussions for details of platforms for which
1209 this change does not apply.
1210
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001211- Issue #5759: float() didn't call __float__ on str subclasses.
1212
Georg Brandlabc38772009-04-12 15:51:51 +00001213- The string.maketrans() function is deprecated; there is a new static method
1214 maketrans() on the bytes and bytearray classes. This removes confusion about
1215 the types string.maketrans() is supposed to work with, and mirrors the
1216 methods available on the str class.
1217
R. David Murraydc6da8a2009-04-09 22:16:43 +00001218- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinsone94c6792009-02-02 20:36:42 +00001518 the type definition cmpfunc. The tp_compare slot has been renamed
1519 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001521- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001522 were suppressing all exceptions. These include list() and bytearray().
1523
Mark Dickinson1124e712009-01-28 21:25:58 +00001524- Issue #4707: round(x, n) now returns an integer if x is an integer.
1525 Previously it returned a float.
1526
Antoine Pitroub52ec782009-01-25 16:34:23 +00001527- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1528 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1529 evaluation loop is compiled with a new dispatch mechanism which gives
1530 speedups of up to 20%, depending on the system, on various benchmarks.
1531
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001532- Issue #4874: Most builtin decoders now reject unicode input.

Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001539- Issue #4838: When a module is deallocated, free the memory backing the
1540 optional module state data.
1541
Mark Dickinson8055afd2009-01-17 10:04:45 +00001542- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1543 type to (void *).
1544
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001545- Issue #4935: The overflow checking code in the expandtabs() method common
1546 to str, bytes and bytearray could be optimized away by the compiler, letting
1547 the interpreter segfault instead of raising an error.
1548
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001549- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1550 __next__ method.
1551
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001552- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1553 function no longer attempt to call the __long__ slot to convert an object
1554 to an integer. Only the __int__ and __trunc__ slots are examined.

1559
Antoine Pitrouab868312009-01-10 15:40:25 +00001560- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1561 common cases are optimized thanks to a dedicated fast path and a moderate
1562 amount of loop unrolling.
1563
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001564- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1565 collecting the oldest generation) so that allocating lots of objects without
1566 destroying them does not show quadratic performance. Based on a proposal by
1567 Martin von Löwis at
1568 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1569
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001570- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001571 having been closed (for instance, a read() call could return some
1572 previously buffered data). Patch by Dmitry Vasiliev.
1573
Antoine Pitrou05608432009-01-09 18:53:14 +00001574- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1575 flag to work properly. Furthermore, when specifying -u, the text stdout
1576 and stderr streams have line-by-line buffering enabled (the default being
1577 to buffer arbitrary chunks of data).
1578
Raymond Hettinger35631532009-01-09 03:58:09 +00001579- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1580 instead of ints (reducing its size from 4 to 8 times thereby reducing
1581 Python's overall memory).
1582
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001583- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1584 an existing .py counterpart, override the co_filename attributes of all
1585 code objects if the original filename is obsolete (which can happen if the
1586 file has been renamed, moved, or if it is accessed through different paths).
1587 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1588
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001589- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1590 one byte. Also fixes the meaning of len() so that it returns the number of
1591 items, rather than the size in bytes.
1592
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001593- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1594
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001595- Issue #4747: When the terminal does not use utf-8, executing a script with
1596 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1597
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001598- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

1602 did not get collected.
1603
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001604- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1605 where the tp_hash and tp_dict slots are both NULL.
1606
Georg Brandlccc47b62008-12-28 11:44:14 +00001607- Issue #4759: None is now allowed as the first argument of
1608 bytearray.translate(). It was always allowed for bytes.translate().
1609
Skip Montanaro80072cb2008-12-23 03:51:14 +00001610- Added test case to ensure attempts to read from a file opened for writing
1611 fail.

1617
Antoine Pitrou621601a2008-12-17 23:18:19 +00001618- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00001624- Issue #2173: When getting device encoding, check that return value of
1625 nl_langinfo is not the empty string. This was causing silent build
1626 failures on OS X.
1627
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001628- Issue #4597: Fixed several opcodes that weren't always propagating
1629 exceptions.
1630
1631- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001632 context manager returns a value that cannot be converted to a bool.
1633
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001634- Issue #4445: Replace "sizeof(PyBytesObject)" with
1635 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1636 bytes instances. On a typical machine this saves 3 bytes of memory
1637 (on average) per allocation of a bytes instance.
1638
Christian Heimesa872de52008-12-05 08:26:55 +00001639- Issue #4533: File read operation was dreadfully slow due to a slowly
1640 growing read buffer. Fixed by using the same growth rate algorithm as
1641 Python 2.x.
1642
Antoine Pitrou5504e892008-12-06 21:27:53 +00001643- Issue #4509: Various issues surrounding resize of bytearray objects to
1644 which there are buffer exports (e.g. memoryview instances).
1645
Georg Brandlf9734072008-12-07 15:30:06 +00001646- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1647 method on file objects with closefd=False. The file descriptor is still
1648 kept open but the file object behaves like a closed file. The ``FileIO``
1649 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001658- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1659 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1660 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1661 of using the replace error handler in PyUnicode_DecodeUTF8().
