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 Smith4e260c52010-02-22 18:54:44 +000015- Issue #7988: Fix default alignment to be right aligned for
16 complex.__format__. Now it matches other numeric types.
17
Eric Smith68af50b2010-02-22 14:58:30 +000018- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
19 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
20 and PyOS_string_to_double instead. See issue #5835 for the original
21 deprecations.
22
Antoine Pitrou05b7c562010-02-02 22:47:00 +000023- Issue #7385: Fix a crash in `MemoryView_FromObject` when
24 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
25
Mark Dickinsonbc099642010-01-29 17:27:24 +000026- Issue #7788: Fix an interpreter crash produced by deleting a list
27 slice with very large step value.
28
Eric Smithf7bb5782010-01-27 00:44:57 +000029- Issue #7766: Change sys.getwindowsversion() return value to a named
30 tuple and add the additional members returned in an OSVERSIONINFOEX
31 structure. The new members are service_pack_major, service_pack_minor,
32 suite_mask, and product_type.
33
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000034- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
35 could crash in many places because of the PyByteArray_AS_STRING() macro
36 returning NULL. The macro now returns a statically allocated empty
37 string instead.
38
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000039- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
40 where the right hand operand is a set of constants, by turning the set into
41 a frozenset and pre-building it as a constant. The comparison operation
42 is made against the constant instead of building a new set each time it is
43 executed (a similar optimization already existed which turned a list of
44 constants into a pre-built tuple). Patch and additional tests by Dave
45 Malcolm.
46
Antoine Pitrouf2c54842010-01-13 08:07:53 +000047- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
48 methods of bytes, bytearray and unicode objects by using a common
49 implementation based on stringlib's fast search. Patch by Florent Xicluna.
50
Mark Dickinson45b63652010-01-16 18:10:25 +000051- Issue #7632: Fix various str -> float conversion bugs present in 2.7
52 alpha 2, including: (1) a serious 'wrong output' bug that could
53 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
54 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000055 strings corresponding to subnormal values, (3) a memory leak for
56 some values large enough to cause overflow, and (4) a number of
57 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000058
Benjamin Petersonaea44282010-01-04 01:10:28 +000059- The __complex__ method is now looked up on the class of instances to make it
60 consistent with other special methods.
61
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000062- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
63 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
64
Benjamin Petersond12362a2009-12-30 19:44:54 +000065- Issue #7604: Deleting an unset slotted attribute did not raise an
66 AttributeError.
67
Mark Dickinson9ab44b52009-12-30 16:22:49 +000068- Issue #7534: Fix handling of IEEE specials (infinities, nans,
69 negative zero) in ** operator. The behaviour now conforms to that
70 described in C99 Annex F.
71
Mark Dickinsoncbb62742009-12-27 15:09:50 +000072- Issue #1811: improve accuracy and cross-platform consistency for
73 true division of integers: the result of a/b is now correctly
74 rounded for ints a and b (at least on IEEE 754 platforms), and in
75 particular does not depend on the internal representation of an int.
76
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000077- Issue #6834: replace the implementation for the 'python' and 'pythonw'
78 executables on OSX.
79
80 These executables now work properly with the arch(1) command:
81 ``arch -ppc python`` will start a universal binary version of python
82 in PPC mode (unlike previous releases).
83
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000084- Issue #7466: segmentation fault when the garbage collector is called
85 in the middle of populating a tuple. Patch by Florent Xicluna.
86
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +000087- Issue #7419: setlocale() could crash the interpreter on Windows when called
88 with invalid values.
89
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +000090- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
91 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
92
Ronald Oussoren3c1928a2009-11-19 17:15:31 +000093- Issue #7085: Fix crash when importing some extensions in a thread
94 on MacOSX 10.6.
95
Philip Jenvey1309adb2009-11-17 03:43:14 +000096- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
97
Mark Dickinson6f1d0492009-11-15 13:58:49 +000098- Issue #6970: Remove redundant calls when comparing objects that don't
99 implement the relevant rich comparison methods.
100
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000101- Issue #7298: fixes for range and reversed(range(...)). Iteration
102 over range(a, b, c) incorrectly gave an empty iterator when a, b and
103 c fit in C long but the length of the range did not. Also fix
104 several cases where reversed(range(a, b, c)) gave wrong results, and
105 fix a refleak for reversed(range(a, b, c)) with large arguments.
106
Raymond Hettingerfc438512009-11-01 20:55:33 +0000107- Issue #7244: itertools.izip_longest() no longer ignores exceptions
108 raised during the formation of an output tuple.
109

116
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000117- Support for AtheOS has been completely removed from the code base. It was
118 disabled since Python 3.0.
119
120- Support for several legacy threading libraries has been disabled. These
121 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
122 will be entirely removed in 3.3.
123
Raymond Hettingeraf7adad2009-10-22 11:22:50 +0000124- Peephole constant folding had missed UNARY_POSITIVE.

137 There should be no other effect than a small decrease in memory use.
138 Patch by Christopher Tur Lesniewski-Laas.
139
Antoine Pitrou403ce782009-10-14 17:14:16 +0000140- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when
Antoine Pitrou671141d2009-10-19 19:37:25 +0000141 using byte values greater than 127. Patch by Derk Drukker.
Antoine Pitrou403ce782009-10-14 17:14:16 +0000142
Amaury Forgeot d'Arc7d520792009-10-06 21:03:20 +0000143- Issue #1571184: The Unicode database contains properties for more characters.
144 The tables for code points representing numeric values, white spaces or line
145 breaks are now generated from the official Unicode Character Database files,
146 and include information from the Unihan.txt file.
147
Mark Dickinson2683ab02009-09-29 19:21:35 +0000148- Issue #7019: Raise ValueError when unmarshalling bad long data, instead

179 documentation.
180
Benjamin Petersonf1664ae2009-07-01 01:28:55 +0000181- The deprecated PyCObject has been removed.
182
Mark Dickinson835a6c82009-06-30 15:45:17 +0000183- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
184 This fixes a build failure on HP-UX: int32_t and uint32_t are
185 defined in inttypes.h instead of stdint.h on that platform.

213 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
214 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
215 DeprecationWarning for float arguments passed with the 'L' format
216 code. This will become a TypeError in a future version of Python,
217 to match the behaviour of the other integer format codes.
218
Georg Brandl1e28a272009-12-28 08:41:01 +0000219- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

228 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
229 should used for accessing the d_type and d_name members of structures
230 using PyDescr_COMMON.
231
232- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000233

241
242- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
243 ``const char *`` as the string is stored beyond the call.
244
Benjamin Peterson05159c42009-12-03 03:01:27 +0000245- Issue #2422: When compiled with the ``--with-valgrind`` option, the
246 pymalloc allocator will be automatically disabled when running under
247 Valgrind. This gives improved memory leak detection when running
248 under Valgrind, while taking advantage of pymalloc at other times.

265 bytecode file when it was less then 8 bytes.
266
Mark Dickinson84230a12010-02-18 14:49:50 +0000267- Issue #7633: In the decimal module, Context class methods (with the
268 exception of canonical and is_canonical) now accept instances of int
269 and long wherever a Decimal instance is accepted, and implicitly
270 convert that argument to Decimal. Previously only some arguments
271 were converted.
272
R. David Murray1f449142010-02-11 00:15:05 +0000273- Issue #7835: shelve should no longer produce mysterious warnings during

277 in XML processing instructions and comments. These raw characters are
278 allowed by the XML specification, and are necessary when outputting e.g.
279 PHP code in a processing instruction. Patch by Neil Muller.
280
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000281- Issue #6233: ElementTree failed converting unicode characters to XML

286 specify the compression type.
287
Antoine Pitroub6375f12010-02-04 20:23:24 +0000288- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
289 specified, rather than fall through to AF_PACKET (in the `socket` module).

291 type is specified. Patch by Brian Curtin.
292
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000293- Issue #6939: Fix file I/O objects in the `io` module to keep the original
294 file position when calling `truncate()`. It would previously change the
295 file position to the given argument, which goes against the tradition of
296 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
297
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000298- Issue #7610: Reworked implementation of the internal
299 :class:`zipfile.ZipExtFile` class used to represent files stored inside
300 an archive. The new implementation is significantly faster and can
301 be wrapped in a :class:`io.BufferedReader` object for more speedups.
302 It also solves an issue where interleaved calls to `read()` and
303 `readline()` give wrong results. Patch by Nir Aides.
304
Jesse Noller1f0b6582010-01-27 03:36:01 +0000305- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

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

830
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000831- Issue #7055: test___all__ now greedily detects all modules which have an

929 are always None now.
930
Antoine Pitroud9dfaa92009-06-04 20:32:06 +0000931- Issue #6137: The pickle module now translates module names when loading
932 or dumping pickles with a 2.x-compatible protocol, in order to make data
933 sharing and migration easier. This behaviour can be disabled using the
934 new `fix_imports` optional argument.

989 that would raise SystemError.
990
Raymond Hettinger2bcde142009-05-29 04:52:27 +0000991- Issue #5982: staticmethod and classmethod now expose the wrapped
992 function with __func__.
993
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +0000994- Added support for multiple context managers in the same with-statement.
995 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +0000997- Issue #5829: complex("1e500") no longer raises OverflowError. This
998 makes it consistent with float("1e500") and interpretation of real
999 and imaginary literals.
1000
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001001- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

1004
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001005- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1006 (1) inf and nan strings with trailing whitespace were incorrectly
1007 rejected; (2) parsing of strings representing infinities and nans
1008 was locale aware; and (3) the interpretation of fromhex('-nan')
1009 didn't match that of float('-nan').

Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001014- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1015
R. David Murrayfb123912009-05-28 18:19:00 +00001016- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1017
R. David Murray1f1b9d32009-05-27 20:56:59 +00001018- Issue #6121: pydoc now ignores leading and trailing spaces in the
1019 argument to the 'help' function.
1020
Georg Brandlfaf41492009-05-26 18:31:11 +00001021- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1022 arguments for strings with a space in them.
1023
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001024- collections.namedtuple() was not working with the following field
1025 names: cls, self, tuple, itemgetter, and property.
1026
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001027- In unittest, using a skipping decorator on a class is now equivalent to
1028 skipping every test on the class. The ClassTestSuite class has been removed.
1029
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001030- Issue #6050: Don't fail extracting a directory from a zipfile if
1031 the directory already exists.
1032
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001033- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1034 than an int, which makes some operations possible under 64-bit Linux (e.g.
1035 DN_MULTISHOT with F_NOTIFY).
1036
Antoine Pitrou716c4442009-05-23 19:04:03 +00001037- Issue #5761: Add the name of the underlying file to the repr() of various

1039
R. David Murraycaa27b72009-05-23 18:49:56 +00001040- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1041 by Musashi Tamura, tests by Marcin Bachry.
1042
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001043- Issue #1983: Fix functions taking or returning a process identifier to use
1044 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1045 a process identifier type wider than the standard C integer type.
1046
R. David Murray87e20742009-05-23 01:30:26 +00001047- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1058
Antoine Pitroue4501852009-05-14 18:55:55 +00001059- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1060 library. This means, for example, that opening an UTF-16 text file in
1061 append mode doesn't add a BOM at the end of the file if the file isn't
1062 empty.
1063
R. David Murray74b89242009-05-13 17:33:03 +00001064- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1065 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1066 corrects a pydoc regression.
1067
R. David Murray99352742009-05-07 18:24:38 +00001068- Issue 5955: aifc's close method did not close the file it wrapped,
1069 now it does. This also means getfp method now returns the real fp.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001111
1112Core and Builtins
1113-----------------
1114
Mark Dickinson865e01a2009-05-07 16:37:01 +00001115- Issue #5914: Add new C API function PyOS_string_to_double, and
1116 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1117
Eric Smith741191f2009-05-06 13:08:15 +00001118- Issue #3382: float.__format__, complex.__format__, and %-formatting
1119 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1120 affects nan -> NAN and inf -> INF.
1121
Mark Hammond5a607a32009-05-06 08:04:54 +00001122- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1123 in all operations, including splitdrive, split, etc. splitunc() now issues
1124 a PendingDeprecation warning.
1125
Eric Smith63376222009-05-05 14:04:18 +00001126- Issue #5920: For float.__format__, change the behavior with the
1127 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1128 to be like 'g' but with at least one decimal point and with a
1129 default precision of 12. Previously, the behavior the same but with
1130 a default precision of 6. This more closely matches str(), and
1131 reduces surprises when adding alignment flags to the empty
1132 presentation type. This also affects the new complex.__format__ in
1133 the same way.
1134
Martin v. Löwis011e8422009-05-05 04:43:17 +00001135- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1136
R. David Murrayb18500d2009-05-04 22:59:07 +00001137- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1138 shadowed by classtype's, even if it was None. property now
1139 inserts the __doc__ into the subclass instance __dict__.
1140
Antoine Pitrou244651a2009-05-04 18:56:13 +00001141- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1142 sequences. Patch by Nick Barnes and Victor Stinner.
1143
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001144- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001145
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001146- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1147 received a new method, detach(). detach() disconnects the underlying stream
1148 from the buffer or text IO and returns it.
1149
Mark Dickinson33841c32009-05-01 15:37:04 +00001150- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1151 floats with absolute value over 1e50. Also remove length
1152 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1153 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001154
Eric Smith741191f2009-05-06 13:08:15 +00001155- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001156 format(complex(1, 2./3), '.5') now produces a sensible result.
1157
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001158- Issue #5864: Fix empty format code formatting for floats so that it
1159 never gives more than the requested number of significant digits.
1160
Eric Smith6dc46f52009-04-27 20:39:49 +00001161- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1162 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1163
Eric Smithcc32a112009-04-26 21:35:14 +00001164- Issue #5835: Deprecate PyOS_ascii_formatd.
1165
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001166- Issue #4971: Fix titlecase for characters that are their own
1167 titlecase, but not their own uppercase.
1168
Benjamin Peterson193152c2009-04-25 01:08:45 +00001169- Issue #5283: Setting __class__ in __del__ caused a segfault.
1170
Mark Dickinsonad476da2009-04-23 19:14:16 +00001171- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1172 z involves nans, infs or negative zeros.
1173
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001174- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001175
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001176- Issue #1869 (and many duplicates): make round(x, n) correctly
1177 rounded for a float x, by using the decimal <-> binary conversions
1178 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1179 consistently agrees with format(x, '.2f').
1180
Benjamin Petersonae937c02009-04-18 20:54:08 +00001181- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1182 some builtin types.
1183
Eric Smith0923d1d2009-04-16 20:16:10 +00001184- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1185
Eric Smith35e84722009-04-16 20:21:28 +00001186- Issue #5515: str.format() type 'n' combined with commas and leading
1187 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001188
1189- Implement PEP 378, Format Specifier for Thousands Separator, for
1190 floats.
1191
Mark Dickinson3370cce2009-04-17 22:40:53 +00001192- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001193 1e11, not 1e12. This avoids printing 13 significant digits in
1194 situations where only 12 of them are correct. Example problem
1195 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1196 long time.)
1197
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001198- Issue #1580: On most platforms, use a 'short' float repr: for a
1199 finite float x, repr(x) now outputs a string based on the shortest
1200 sequence of decimal digits that rounds to x. Previous behaviour was
1201 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001202 Another minor difference is that the new repr switches to
1203 exponential notation at 1e16 instead of the previous 1e17; this
1204 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001205
1206 There's a new sys attribute sys.float_repr_style, which takes
1207 the value 'short' to indicate that we're using short float repr,
1208 and 'legacy' if the short float repr isn't available for one
1209 reason or another.
1210
1211 The float repr change involves incorporating David Gay's 'perfect

1224 the types string.maketrans() is supposed to work with, and mirrors the
1225 methods available on the str class.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00001530- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001531 were suppressing all exceptions. These include list() and bytearray().
1532
Mark Dickinson1124e712009-01-28 21:25:58 +00001533- Issue #4707: round(x, n) now returns an integer if x is an integer.
1534 Previously it returned a float.
1535
Antoine Pitroub52ec782009-01-25 16:34:23 +00001536- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1537 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1538 evaluation loop is compiled with a new dispatch mechanism which gives
1539 speedups of up to 20%, depending on the system, on various benchmarks.

1550
Mark Dickinson8055afd2009-01-17 10:04:45 +00001551- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1552 type to (void *).
1553
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001554- Issue #4935: The overflow checking code in the expandtabs() method common
1555 to str, bytes and bytearray could be optimized away by the compiler, letting
1556 the interpreter segfault instead of raising an error.
1557
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001558- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1559 __next__ method.
1560
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001561- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1568
Antoine Pitrouab868312009-01-10 15:40:25 +00001569- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1570 common cases are optimized thanks to a dedicated fast path and a moderate
1571 amount of loop unrolling.
1572
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001573- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1574 collecting the oldest generation) so that allocating lots of objects without
1575 destroying them does not show quadratic performance. Based on a proposal by
1576 Martin von Löwis at
1577 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1578
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001579- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001580 having been closed (for instance, a read() call could return some
1581 previously buffered data). Patch by Dmitry Vasiliev.
1582
Antoine Pitrou05608432009-01-09 18:53:14 +00001583- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1584 flag to work properly. Furthermore, when specifying -u, the text stdout
1585 and stderr streams have line-by-line buffering enabled (the default being
1586 to buffer arbitrary chunks of data).
1587
Raymond Hettinger35631532009-01-09 03:58:09 +00001588- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1589 instead of ints (reducing its size from 4 to 8 times thereby reducing
1590 Python's overall memory).
1591
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001592- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1593 an existing .py counterpart, override the co_filename attributes of all
1594 code objects if the original filename is obsolete (which can happen if the
1595 file has been renamed, moved, or if it is accessed through different paths).
1596 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1597
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001598- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1599 one byte. Also fixes the meaning of len() so that it returns the number of
1600 items, rather than the size in bytes.
1601
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001602- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1603
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001604- Issue #4747: When the terminal does not use utf-8, executing a script with
1605 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1606

1611 did not get collected.
1612
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001613- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1614 where the tp_hash and tp_dict slots are both NULL.
1615
Georg Brandlccc47b62008-12-28 11:44:14 +00001616- Issue #4759: None is now allowed as the first argument of
1617 bytearray.translate(). It was always allowed for bytes.translate().
1618
Skip Montanaro80072cb2008-12-23 03:51:14 +00001619- Added test case to ensure attempts to read from a file opened for writing
1620 fail.

1626
Antoine Pitrou621601a2008-12-17 23:18:19 +00001627- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00001633- Issue #2173: When getting device encoding, check that return value of
1634 nl_langinfo is not the empty string. This was causing silent build
1635 failures on OS X.
1636
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001637- Issue #4597: Fixed several opcodes that weren't always propagating
1638 exceptions.
1639
1640- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001641 context manager returns a value that cannot be converted to a bool.
1642
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001643- Issue #4445: Replace "sizeof(PyBytesObject)" with
1644 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1645 bytes instances. On a typical machine this saves 3 bytes of memory
1646 (on average) per allocation of a bytes instance.
1647
Christian Heimesa872de52008-12-05 08:26:55 +00001648- Issue #4533: File read operation was dreadfully slow due to a slowly
1649 growing read buffer. Fixed by using the same growth rate algorithm as
1650 Python 2.x.
1651
Antoine Pitrou5504e892008-12-06 21:27:53 +00001652- Issue #4509: Various issues surrounding resize of bytearray objects to
1653 which there are buffer exports (e.g. memoryview instances).
1654
Georg Brandlf9734072008-12-07 15:30:06 +00001655- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1656 method on file objects with closefd=False. The file descriptor is still
1657 kept open but the file object behaves like a closed file. The ``FileIO``
1658 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00001667- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1668 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1669 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1670 of using the replace error handler in PyUnicode_DecodeUTF8().
