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
Antoine Pitrou05b7c562010-02-02 22:47:00 +000015- Issue #7385: Fix a crash in `MemoryView_FromObject` when
16 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
17
Mark Dickinsonbc099642010-01-29 17:27:24 +000018- Issue #7788: Fix an interpreter crash produced by deleting a list
19 slice with very large step value.
20
Eric Smithf7bb5782010-01-27 00:44:57 +000021- Issue #7766: Change sys.getwindowsversion() return value to a named
22 tuple and add the additional members returned in an OSVERSIONINFOEX
23 structure. The new members are service_pack_major, service_pack_minor,
24 suite_mask, and product_type.
25
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000026- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
27 could crash in many places because of the PyByteArray_AS_STRING() macro
28 returning NULL. The macro now returns a statically allocated empty
29 string instead.
30
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000031- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
32 where the right hand operand is a set of constants, by turning the set into
33 a frozenset and pre-building it as a constant. The comparison operation
34 is made against the constant instead of building a new set each time it is
35 executed (a similar optimization already existed which turned a list of
36 constants into a pre-built tuple). Patch and additional tests by Dave
37 Malcolm.
38
Antoine Pitrouf2c54842010-01-13 08:07:53 +000039- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
40 methods of bytes, bytearray and unicode objects by using a common
41 implementation based on stringlib's fast search. Patch by Florent Xicluna.
42
Mark Dickinson45b63652010-01-16 18:10:25 +000043- Issue #7632: Fix various str -> float conversion bugs present in 2.7
44 alpha 2, including: (1) a serious 'wrong output' bug that could
45 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
46 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000047 strings corresponding to subnormal values, (3) a memory leak for
48 some values large enough to cause overflow, and (4) a number of
49 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000050
Benjamin Petersonaea44282010-01-04 01:10:28 +000051- The __complex__ method is now looked up on the class of instances to make it
52 consistent with other special methods.
53
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000054- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
55 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
56
Benjamin Petersond12362a2009-12-30 19:44:54 +000057- Issue #7604: Deleting an unset slotted attribute did not raise an
58 AttributeError.
59
Mark Dickinson9ab44b52009-12-30 16:22:49 +000060- Issue #7534: Fix handling of IEEE specials (infinities, nans,
61 negative zero) in ** operator. The behaviour now conforms to that
62 described in C99 Annex F.
63
Mark Dickinsoncbb62742009-12-27 15:09:50 +000064- Issue #1811: improve accuracy and cross-platform consistency for
65 true division of integers: the result of a/b is now correctly
66 rounded for ints a and b (at least on IEEE 754 platforms), and in
67 particular does not depend on the internal representation of an int.
68
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000069- Issue #6834: replace the implementation for the 'python' and 'pythonw'
70 executables on OSX.
71
72 These executables now work properly with the arch(1) command:
73 ``arch -ppc python`` will start a universal binary version of python
74 in PPC mode (unlike previous releases).
75
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000076- Issue #7466: segmentation fault when the garbage collector is called
77 in the middle of populating a tuple. Patch by Florent Xicluna.
78
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +000079- Issue #7419: setlocale() could crash the interpreter on Windows when called
80 with invalid values.
81
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +000082- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
83 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
84
Ronald Oussoren3c1928a2009-11-19 17:15:31 +000085- Issue #7085: Fix crash when importing some extensions in a thread
86 on MacOSX 10.6.
87
Philip Jenvey1309adb2009-11-17 03:43:14 +000088- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
89
Mark Dickinson6f1d0492009-11-15 13:58:49 +000090- Issue #6970: Remove redundant calls when comparing objects that don't
91 implement the relevant rich comparison methods.
92
Mark Dickinsond550c9a2009-11-15 09:57:26 +000093- Issue #7298: fixes for range and reversed(range(...)). Iteration
94 over range(a, b, c) incorrectly gave an empty iterator when a, b and
95 c fit in C long but the length of the range did not. Also fix
96 several cases where reversed(range(a, b, c)) gave wrong results, and
97 fix a refleak for reversed(range(a, b, c)) with large arguments.
98
Raymond Hettingerfc438512009-11-01 20:55:33 +000099- Issue #7244: itertools.izip_longest() no longer ignores exceptions
100 raised during the formation of an output tuple.
101
Benjamin Petersonb2e796a2009-10-28 21:59:39 +0000102- Issue #3297: On wide unicode builds, do not split unicode characters into
103 surrogates.

108
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000109- Support for AtheOS has been completely removed from the code base. It was
110 disabled since Python 3.0.
111
112- Support for several legacy threading libraries has been disabled. These
113 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
114 will be entirely removed in 3.3.
115
Raymond Hettingeraf7adad2009-10-22 11:22:50 +0000116- Peephole constant folding had missed UNARY_POSITIVE.
117
Antoine Pitrou011bd622009-10-20 21:52:47 +0000118- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
119 fixes the problem of some exceptions being thrown at shutdown when the
120 interpreter is killed. Patch by Adam Olsen.
121
Antoine Pitrou671141d2009-10-19 19:37:25 +0000122- Issue #7147: Remove support for compiling Python without complex number

129 There should be no other effect than a small decrease in memory use.
130 Patch by Christopher Tur Lesniewski-Laas.
131
Antoine Pitrou403ce782009-10-14 17:14:16 +0000132- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when
Antoine Pitrou671141d2009-10-19 19:37:25 +0000133 using byte values greater than 127. Patch by Derk Drukker.
Antoine Pitrou403ce782009-10-14 17:14:16 +0000134

136 The tables for code points representing numeric values, white spaces or line
137 breaks are now generated from the official Unicode Character Database files,
138 and include information from the Unihan.txt file.
139
Mark Dickinson2683ab02009-09-29 19:21:35 +0000140- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
141 of producing internally inconsistent Python longs.
142

Raymond Hettingere805ecc2009-07-27 20:16:37 +0000161- Issue #6573: set.union() stopped processing inputs if an instance of self
162 occurred in the argument chain.
163
R. David Murray046f7232009-07-19 02:22:05 +0000164- Issue #6070: On posix platforms import no longer copies the execute bit

203
Mark Dickinsonde604012010-01-01 19:27:32 +0000204- Issue #5080: The argument parsing functions PyArg_ParseTuple,
205 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
206 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
207 DeprecationWarning for float arguments passed with the 'L' format
208 code. This will become a TypeError in a future version of Python,
209 to match the behaviour of the other integer format codes.
210

220 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
221 should used for accessing the d_type and d_name members of structures
222 using PyDescr_COMMON.
223
224- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000225

227
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000228- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
229 PyCode_Addr2Line().
230
231- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
232 object at a specified file, function, and line number.
233
234- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
235 ``const char *`` as the string is stored beyond the call.
236
Benjamin Peterson05159c42009-12-03 03:01:27 +0000237- Issue #2422: When compiled with the ``--with-valgrind`` option, the
238 pymalloc allocator will be automatically disabled when running under
239 Valgrind. This gives improved memory leak detection when running
240 under Valgrind, while taking advantage of pymalloc at other times.

251 type is specified. Patch by Brian Curtin.
252
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000253- Issue #6939: Fix file I/O objects in the `io` module to keep the original
254 file position when calling `truncate()`. It would previously change the
255 file position to the given argument, which goes against the tradition of
256 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
257
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000258- Issue #7610: Reworked implementation of the internal
259 :class:`zipfile.ZipExtFile` class used to represent files stored inside
260 an archive. The new implementation is significantly faster and can
261 be wrapped in a :class:`io.BufferedReader` object for more speedups.
262 It also solves an issue where interleaved calls to `read()` and
263 `readline()` give wrong results. Patch by Nir Aides.
264
Jesse Noller1f0b6582010-01-27 03:36:01 +0000265- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

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

762 leak-chasing test runs give sensible results. The previous method of

919Core and Builtins
920-----------------
921
Martin v. Löwis8ed91b22009-05-29 16:22:26 +0000922- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
923 of the command line.
924
Martin v. Löwisc15bdef2009-05-29 14:47:46 +0000925- Issue #6012: Add cleanup support to O& argument parsing.
926
Eric Smith41669ca2009-05-23 14:23:22 +0000927- Issue #6089: Fixed str.format with certain invalid field specifiers
928 that would raise SystemError.
929
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000930- Issue #5982: staticmethod and classmethod now expose the wrapped
931 function with __func__.
932
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000933- Added support for multiple context managers in the same with-statement.
934 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +0000935
Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000936- Issue #5829: complex("1e500") no longer raises OverflowError. This
937 makes it consistent with float("1e500") and interpretation of real
938 and imaginary literals.
939
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +0000940- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
941
R. David Murraydd226ea2009-05-13 12:27:21 +0000942- Issue #5994: the marshal module now has docstrings.
943
Mark Dickinsond1ec8b22009-05-11 15:45:15 +0000944- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
945 (1) inf and nan strings with trailing whitespace were incorrectly
946 rejected; (2) parsing of strings representing infinities and nans
947 was locale aware; and (3) the interpretation of fromhex('-nan')
948 didn't match that of float('-nan').

951-------
952
Martin v. Löwisb6a748b2009-05-29 15:23:17 +0000953- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
954
R. David Murrayfb123912009-05-28 18:19:00 +0000955- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
956
R. David Murray1f1b9d32009-05-27 20:56:59 +0000957- Issue #6121: pydoc now ignores leading and trailing spaces in the
958 argument to the 'help' function.
959
Georg Brandlfaf41492009-05-26 18:31:11 +0000960- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
961 arguments for strings with a space in them.
962
Raymond Hettinger089ba7f2009-05-27 00:38:24 +0000963- collections.namedtuple() was not working with the following field
964 names: cls, self, tuple, itemgetter, and property.
965
Benjamin Peterson14a3dd72009-05-25 00:51:58 +0000966- In unittest, using a skipping decorator on a class is now equivalent to
967 skipping every test on the class. The ClassTestSuite class has been removed.
968
Martin v. Löwis70ccd162009-05-24 19:47:22 +0000969- Issue #6050: Don't fail extracting a directory from a zipfile if
970 the directory already exists.
971
Antoine Pitrou61f77b52009-05-24 15:46:13 +0000972- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
973 than an int, which makes some operations possible under 64-bit Linux (e.g.
974 DN_MULTISHOT with F_NOTIFY).
975
Antoine Pitrou716c4442009-05-23 19:04:03 +0000976- Issue #5761: Add the name of the underlying file to the repr() of various
977 IO objects.
978
R. David Murraycaa27b72009-05-23 18:49:56 +0000979- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
980 by Musashi Tamura, tests by Marcin Bachry.
981
Antoine Pitrouc3ee1662009-05-23 16:02:33 +0000982- Issue #1983: Fix functions taking or returning a process identifier to use
983 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
984 a process identifier type wider than the standard C integer type.
985
R. David Murray87e20742009-05-23 01:30:26 +0000986- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
987 Patch by Farhan Ahmad, test by Marcin Bachry.
988
Antoine Pitrou6e610062009-05-15 17:04:50 +0000989- Issue #2116: Weak references and weak dictionaries now support copy()ing and
990 deepcopy()ing.
991
Antoine Pitrouc1d09362009-05-15 12:15:51 +0000992- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
993
Antoine Pitrou37d1c182009-05-14 21:54:00 +0000994- Issue #5918: Fix a crash in the parser module.
995
Antoine Pitrou2ca24f02009-05-14 21:30:46 +0000996- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
997
Antoine Pitroue4501852009-05-14 18:55:55 +0000998- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
999 library. This means, for example, that opening an UTF-16 text file in
1000 append mode doesn't add a BOM at the end of the file if the file isn't
1001 empty.
1002
R. David Murray74b89242009-05-13 17:33:03 +00001003- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1004 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1005 corrects a pydoc regression.
1006
R. David Murray99352742009-05-07 18:24:38 +00001007- Issue 5955: aifc's close method did not close the file it wrapped,
1008 now it does. This also means getfp method now returns the real fp.
1009
Benjamin Peterson932073a2009-05-23 16:14:33 +00001010Installation
1011------------
1012
1013- Issue #6047: fullinstall has been removed because Python 3's executable will
1014 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001015
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00001016- Lib/smtpd.py is no longer installed as a script.

Martin v. Löwisdb1c3992009-05-23 10:38:26 +00001025- Issue #6093: Fix off-by-one error in locale.strxfrm.
1026
Benjamin Peterson744af442009-05-23 18:51:49 +00001027- The _functools and _locale modules are now built into the libpython shared
1028 library instead of as extension modules.
Benjamin Peterson3dc22e82009-05-23 17:09:43 +00001029
Antoine Pitrou20327222009-05-24 20:39:11 +00001030Build
1031-----
1032
1033- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
1034 and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
1035 Clinton Roy.
1036
Brett Cannon1262e7c2009-05-11 01:47:11 +00001037Tests
1038-----
1039
1040- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1041 tests on darwin even when the OS was installed on a case-sensitive
1042 filesystem. Also fixed tests that should not be run when
1043 sys.dont_write_bytecode is true.

1047================================
1048
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001049*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001050
1051Core and Builtins
1052-----------------
1053
Mark Dickinson865e01a2009-05-07 16:37:01 +00001054- Issue #5914: Add new C API function PyOS_string_to_double, and
1055 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1056
Eric Smith741191f2009-05-06 13:08:15 +00001057- Issue #3382: float.__format__, complex.__format__, and %-formatting
1058 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1059 affects nan -> NAN and inf -> INF.
1060
Mark Hammond5a607a32009-05-06 08:04:54 +00001061- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1062 in all operations, including splitdrive, split, etc. splitunc() now issues
1063 a PendingDeprecation warning.
1064
Eric Smith63376222009-05-05 14:04:18 +00001065- Issue #5920: For float.__format__, change the behavior with the
1066 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1067 to be like 'g' but with at least one decimal point and with a
1068 default precision of 12. Previously, the behavior the same but with
1069 a default precision of 6. This more closely matches str(), and
1070 reduces surprises when adding alignment flags to the empty
1071 presentation type. This also affects the new complex.__format__ in
1072 the same way.
1073
Martin v. Löwis011e8422009-05-05 04:43:17 +00001074- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1075
R. David Murrayb18500d2009-05-04 22:59:07 +00001076- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1077 shadowed by classtype's, even if it was None. property now
1078 inserts the __doc__ into the subclass instance __dict__.
1079
Antoine Pitrou244651a2009-05-04 18:56:13 +00001080- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1081 sequences. Patch by Nick Barnes and Victor Stinner.
1082
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001083- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001084
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001085- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1086 received a new method, detach(). detach() disconnects the underlying stream
1087 from the buffer or text IO and returns it.
1088
Mark Dickinson33841c32009-05-01 15:37:04 +00001089- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1090 floats with absolute value over 1e50. Also remove length
1091 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1092 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001093
Eric Smith741191f2009-05-06 13:08:15 +00001094- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001095 format(complex(1, 2./3), '.5') now produces a sensible result.
1096
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001097- Issue #5864: Fix empty format code formatting for floats so that it
1098 never gives more than the requested number of significant digits.
1099
Eric Smith6dc46f52009-04-27 20:39:49 +00001100- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1101 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1102
Eric Smithcc32a112009-04-26 21:35:14 +00001103- Issue #5835: Deprecate PyOS_ascii_formatd.
1104
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001105- Issue #4971: Fix titlecase for characters that are their own
1106 titlecase, but not their own uppercase.
1107
Benjamin Peterson193152c2009-04-25 01:08:45 +00001108- Issue #5283: Setting __class__ in __del__ caused a segfault.
1109
Mark Dickinsonad476da2009-04-23 19:14:16 +00001110- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1111 z involves nans, infs or negative zeros.
1112
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001113- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001114
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001115- Issue #1869 (and many duplicates): make round(x, n) correctly
1116 rounded for a float x, by using the decimal <-> binary conversions
1117 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1118 consistently agrees with format(x, '.2f').
1119
Benjamin Petersonae937c02009-04-18 20:54:08 +00001120- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1121 some builtin types.
1122
Eric Smith0923d1d2009-04-16 20:16:10 +00001123- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1124
Eric Smith35e84722009-04-16 20:21:28 +00001125- Issue #5515: str.format() type 'n' combined with commas and leading
1126 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001127
1128- Implement PEP 378, Format Specifier for Thousands Separator, for
1129 floats.
1130
Mark Dickinson3370cce2009-04-17 22:40:53 +00001131- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001132 1e11, not 1e12. This avoids printing 13 significant digits in
1133 situations where only 12 of them are correct. Example problem
1134 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1135 long time.)
1136
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001137- Issue #1580: On most platforms, use a 'short' float repr: for a
1138 finite float x, repr(x) now outputs a string based on the shortest
1139 sequence of decimal digits that rounds to x. Previous behaviour was
1140 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001141 Another minor difference is that the new repr switches to
1142 exponential notation at 1e16 instead of the previous 1e17; this
1143 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001144
1145 There's a new sys attribute sys.float_repr_style, which takes
1146 the value 'short' to indicate that we're using short float repr,
1147 and 'legacy' if the short float repr isn't available for one
1148 reason or another.
1149
1150 The float repr change involves incorporating David Gay's 'perfect
1151 rounding' code into the Python core (it's in Python/dtoa.c). As a
1152 secondary consequence, all string-to-float and float-to-string
1153 conversions (including all float formatting operations) will be
1154 correctly rounded on these platforms.
1155
1156 See issue 1580 discussions for details of platforms for which
1157 this change does not apply.
1158
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001159- Issue #5759: float() didn't call __float__ on str subclasses.
1160
Georg Brandlabc38772009-04-12 15:51:51 +00001161- The string.maketrans() function is deprecated; there is a new static method
1162 maketrans() on the bytes and bytearray classes. This removes confusion about
1163 the types string.maketrans() is supposed to work with, and mirrors the
1164 methods available on the str class.
1165
R. David Murraydc6da8a2009-04-09 22:16:43 +00001166- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1167 its clarity and its speed.
1168
Matthias Klose091c7b12009-04-07 13:24:27 +00001169- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1170 to avoid compiler warnings.
1171
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001172- Issue #3739: The unicode-internal encoder now reports the number of characters
1173 consumed like any other encoder (instead of the number of bytes).

1184 specific Python version.
1185
Raymond Hettingereb816952009-05-29 01:22:18 +00001186- Issue #5150: IDLE's format menu now has an option to strip trailing
1187 whitespace.
1188
Vinay Sajipaffbd872009-06-11 10:11:47 +00001189- Issue #5940: distutils.command.build_clib.check_library_list was not doing
Tarek Ziadédd9f65f2009-05-06 07:26:24 +00001190 the right type checkings anymore.
1191
Thomas Heller00cfc372009-05-05 19:04:40 +00001192- Issue #4875: On win32, ctypes.util.find_library does no longer

Antoine Pitroua9f48a02009-05-02 21:41:14 +00001208- Issue #5084: unpickling now interns the attribute names of pickled objects,
1209 saving memory and avoiding growth in size of subsequent pickles. Proposal
1210 and original patch by Jake McGuire.

1404 forever on incomplete input. That caused tarfile.open() to hang when used
1405 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Antoine Pitrou14b78f52009-01-09 22:27:08 +00001512- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1513 collecting the oldest generation) so that allocating lots of objects without
1514 destroying them does not show quadratic performance. Based on a proposal by
1515 Martin von Löwis at
1516 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1517
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001518- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001519 having been closed (for instance, a read() call could return some
1520 previously buffered data). Patch by Dmitry Vasiliev.
1521
Antoine Pitrou05608432009-01-09 18:53:14 +00001522- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1523 flag to work properly. Furthermore, when specifying -u, the text stdout
1524 and stderr streams have line-by-line buffering enabled (the default being
1525 to buffer arbitrary chunks of data).
1526
Raymond Hettinger35631532009-01-09 03:58:09 +00001527- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1528 instead of ints (reducing its size from 4 to 8 times thereby reducing
1529 Python's overall memory).
1530
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001531- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1532 an existing .py counterpart, override the co_filename attributes of all
1533 code objects if the original filename is obsolete (which can happen if the
1534 file has been renamed, moved, or if it is accessed through different paths).
1535 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1536
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001537- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1538 one byte. Also fixes the meaning of len() so that it returns the number of
1539 items, rather than the size in bytes.
1540
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001541- Issue #4075: Use OutputDebugStringW in Py_FatalError.

1550 did not get collected.
1551
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001552- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1553 where the tp_hash and tp_dict slots are both NULL.
1554
Georg Brandlccc47b62008-12-28 11:44:14 +00001555- Issue #4759: None is now allowed as the first argument of
1556 bytearray.translate(). It was always allowed for bytes.translate().
1557
Skip Montanaro80072cb2008-12-23 03:51:14 +00001558- Added test case to ensure attempts to read from a file opened for writing
1559 fail.
1560

1565
Antoine Pitrou621601a2008-12-17 23:18:19 +00001566- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

1574 failures on OS X.
1575
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001576- Issue #4597: Fixed several opcodes that weren't always propagating

1578
1579- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001580 context manager returns a value that cannot be converted to a bool.
1581
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001582- Issue #4445: Replace "sizeof(PyBytesObject)" with
1583 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1584 bytes instances. On a typical machine this saves 3 bytes of memory
1585 (on average) per allocation of a bytes instance.
1586
Christian Heimesa872de52008-12-05 08:26:55 +00001587- Issue #4533: File read operation was dreadfully slow due to a slowly
1588 growing read buffer. Fixed by using the same growth rate algorithm as
1589 Python 2.x.
1590
Antoine Pitrou5504e892008-12-06 21:27:53 +00001591- Issue #4509: Various issues surrounding resize of bytearray objects to
1592 which there are buffer exports (e.g. memoryview instances).
1593
Georg Brandlf9734072008-12-07 15:30:06 +00001594- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1595 method on file objects with closefd=False. The file descriptor is still
1596 kept open but the file object behaves like a closed file. The ``FileIO``
1597 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00001599- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1605
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001606- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1607 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1608 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1609 of using the replace error handler in PyUnicode_DecodeUTF8().
