12Core and Builtins
13-----------------
14
Larry Hastings1373a072010-02-24 22:49:58 +000015- Issue #5939: Add additional runtime checking to ensure a valid capsule
16 in Modules/_ctypes/callproc.c.
17
Eric Smith0facd772010-02-24 15:42:29 +000018- Issue #7309: Fix unchecked attribute access when converting
19 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
20 strings.
21
Eric Smithabb28c62010-02-23 00:22:24 +000022- Issue #6902: Fix problem with built-in types format incorrectly with
23 0 padding.
24
Eric Smith4e260c52010-02-22 18:54:44 +000025- Issue #7988: Fix default alignment to be right aligned for
26 complex.__format__. Now it matches other numeric types.
27
Eric Smith68af50b2010-02-22 14:58:30 +000028- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
29 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
30 and PyOS_string_to_double instead. See issue #5835 for the original
31 deprecations.
32
Antoine Pitrou05b7c562010-02-02 22:47:00 +000033- Issue #7385: Fix a crash in `MemoryView_FromObject` when
34 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
35
Mark Dickinsonbc099642010-01-29 17:27:24 +000036- Issue #7788: Fix an interpreter crash produced by deleting a list
37 slice with very large step value.
38
Eric Smithf7bb5782010-01-27 00:44:57 +000039- Issue #7766: Change sys.getwindowsversion() return value to a named
40 tuple and add the additional members returned in an OSVERSIONINFOEX
41 structure. The new members are service_pack_major, service_pack_minor,
42 suite_mask, and product_type.
43
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000044- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
45 could crash in many places because of the PyByteArray_AS_STRING() macro
46 returning NULL. The macro now returns a statically allocated empty
47 string instead.
48
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000049- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
50 where the right hand operand is a set of constants, by turning the set into
51 a frozenset and pre-building it as a constant. The comparison operation
52 is made against the constant instead of building a new set each time it is
53 executed (a similar optimization already existed which turned a list of
54 constants into a pre-built tuple). Patch and additional tests by Dave
55 Malcolm.
56
Antoine Pitrouf2c54842010-01-13 08:07:53 +000057- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
58 methods of bytes, bytearray and unicode objects by using a common
59 implementation based on stringlib's fast search. Patch by Florent Xicluna.
60
Mark Dickinson45b63652010-01-16 18:10:25 +000061- Issue #7632: Fix various str -> float conversion bugs present in 2.7
62 alpha 2, including: (1) a serious 'wrong output' bug that could
63 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
64 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000065 strings corresponding to subnormal values, (3) a memory leak for
66 some values large enough to cause overflow, and (4) a number of
67 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000068
Benjamin Petersonaea44282010-01-04 01:10:28 +000069- The __complex__ method is now looked up on the class of instances to make it
70 consistent with other special methods.
71
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000072- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
73 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
74
Benjamin Petersond12362a2009-12-30 19:44:54 +000075- Issue #7604: Deleting an unset slotted attribute did not raise an
76 AttributeError.
77
Mark Dickinson9ab44b52009-12-30 16:22:49 +000078- Issue #7534: Fix handling of IEEE specials (infinities, nans,
79 negative zero) in ** operator. The behaviour now conforms to that
80 described in C99 Annex F.
81
Mark Dickinsoncbb62742009-12-27 15:09:50 +000082- Issue #1811: improve accuracy and cross-platform consistency for
83 true division of integers: the result of a/b is now correctly
84 rounded for ints a and b (at least on IEEE 754 platforms), and in
85 particular does not depend on the internal representation of an int.
86
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000087- Issue #6834: replace the implementation for the 'python' and 'pythonw'
88 executables on OSX.
89
90 These executables now work properly with the arch(1) command:
91 ``arch -ppc python`` will start a universal binary version of python
92 in PPC mode (unlike previous releases).
93
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000094- Issue #7466: segmentation fault when the garbage collector is called
95 in the middle of populating a tuple. Patch by Florent Xicluna.
96

98 with invalid values.
99
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000100- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
101 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).

104 on MacOSX 10.6.
105
Philip Jenvey1309adb2009-11-17 03:43:14 +0000106- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
107
Mark Dickinson6f1d0492009-11-15 13:58:49 +0000108- Issue #6970: Remove redundant calls when comparing objects that don't
109 implement the relevant rich comparison methods.
110
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000111- Issue #7298: fixes for range and reversed(range(...)). Iteration
112 over range(a, b, c) incorrectly gave an empty iterator when a, b and
113 c fit in C long but the length of the range did not. Also fix
114 several cases where reversed(range(a, b, c)) gave wrong results, and
115 fix a refleak for reversed(range(a, b, c)) with large arguments.
116
Raymond Hettingerfc438512009-11-01 20:55:33 +0000117- Issue #7244: itertools.izip_longest() no longer ignores exceptions

126
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000127- Support for AtheOS has been completely removed from the code base. It was
128 disabled since Python 3.0.
129
130- Support for several legacy threading libraries has been disabled. These
131 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
132 will be entirely removed in 3.3.

148 Patch by Christopher Tur Lesniewski-Laas.
149
Antoine Pitrou403ce782009-10-14 17:14:16 +0000150- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when
Antoine Pitrou671141d2009-10-19 19:37:25 +0000151 using byte values greater than 127. Patch by Derk Drukker.

308 type is specified. Patch by Brian Curtin.
309
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000310- Issue #6939: Fix file I/O objects in the `io` module to keep the original

Antoine Pitroua32f9a22010-01-27 21:18:57 +0000315- Issue #7610: Reworked implementation of the internal
316 :class:`zipfile.ZipExtFile` class used to represent files stored inside
317 an archive. The new implementation is significantly faster and can
318 be wrapped in a :class:`io.BufferedReader` object for more speedups.
319 It also solves an issue where interleaved calls to `read()` and
320 `readline()` give wrong results. Patch by Nir Aides.

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

487 support the same flexibility as the CPython command line itself.

817
R. David Murray35768ad2009-11-15 00:23:21 +0000818- Issue #7324: add a sanity check to regrtest argument parsing to

822 a test fails. Can be combined with -j.
823
Antoine Pitrou060cee22009-11-13 16:29:04 +0000824- Issue #6551: test_zipimport could import and then destroy some modules of
825 the encodings package, which would make other tests fail further down
826 the road because the internally cached encoders and decoders would point
827 to empty global variables.
828
Antoine Pitrou941ee882009-11-11 20:59:38 +0000829- Issue #7295: Do not use a hardcoded file name in test_tarfile.

840 calling methods on the object.
841
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000842- Issue #7222: Make thread "reaping" more reliable so that reference
843 leak-chasing test runs give sensible results. The previous method of
844 reaping threads could return successfully while some Thread objects were
845 still referenced. This also introduces a new private function:
846 :func:`_thread._count()`.
847
R. David Murray27144602009-10-19 15:26:16 +0000848- Issue #7151: fixed regrtest -j so that output to stderr from a test no
849 longer runs the risk of causing the worker thread to fail.
850
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000851- Issue #7055: test___all__ now greedily detects all modules which have an
852 __all__ attribute, rather than using a hardcoded and incomplete list.
853

Mark Dickinson2e304402009-10-04 18:43:54 +0000858- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
859
Brett Cannon3c273842009-07-20 00:14:29 +0000860- Fixed tests in importlib.test.source.test_abc_loader that were masking
861 the proper exceptions that should be raised for missing or improper code
862 object bytecode.
863
Brett Cannonb49c70c2009-07-15 04:08:33 +0000864- Removed importlib's custom test discovery code and switched to

1027 rejected; (2) parsing of strings representing infinities and nans
1028 was locale aware; and (3) the interpretation of fromhex('-nan')
1029 didn't match that of float('-nan').

1052
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001053- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1054 than an int, which makes some operations possible under 64-bit Linux (e.g.

1133-----------------
1134
Mark Dickinson865e01a2009-05-07 16:37:01 +00001135- Issue #5914: Add new C API function PyOS_string_to_double, and
1136 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1137
Eric Smith741191f2009-05-06 13:08:15 +00001138- Issue #3382: float.__format__, complex.__format__, and %-formatting
1139 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1140 affects nan -> NAN and inf -> INF.
1141
Mark Hammond5a607a32009-05-06 08:04:54 +00001142- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1143 in all operations, including splitdrive, split, etc. splitunc() now issues
1144 a PendingDeprecation warning.
1145
Eric Smith63376222009-05-05 14:04:18 +00001146- Issue #5920: For float.__format__, change the behavior with the
1147 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1148 to be like 'g' but with at least one decimal point and with a
1149 default precision of 12. Previously, the behavior the same but with
1150 a default precision of 6. This more closely matches str(), and
1151 reduces surprises when adding alignment flags to the empty
1152 presentation type. This also affects the new complex.__format__ in
1153 the same way.
1154
Martin v. Löwis011e8422009-05-05 04:43:17 +00001155- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1158 shadowed by classtype's, even if it was None. property now
1159 inserts the __doc__ into the subclass instance __dict__.
1160
Antoine Pitrou244651a2009-05-04 18:56:13 +00001161- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1162 sequences. Patch by Nick Barnes and Victor Stinner.
1163
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001164- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001165
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001166- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1167 received a new method, detach(). detach() disconnects the underlying stream
1168 from the buffer or text IO and returns it.
1169
Mark Dickinson33841c32009-05-01 15:37:04 +00001170- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1171 floats with absolute value over 1e50. Also remove length
1172 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1173 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001175- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001176 format(complex(1, 2./3), '.5') now produces a sensible result.
1177
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001178- Issue #5864: Fix empty format code formatting for floats so that it
1179 never gives more than the requested number of significant digits.
1180
Eric Smith6dc46f52009-04-27 20:39:49 +00001181- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1182 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.

Mark Dickinsonad476da2009-04-23 19:14:16 +00001191- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1192 z involves nans, infs or negative zeros.
1193
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001194- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001195
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001196- Issue #1869 (and many duplicates): make round(x, n) correctly
1197 rounded for a float x, by using the decimal <-> binary conversions
1198 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1199 consistently agrees with format(x, '.2f').
1200
Benjamin Petersonae937c02009-04-18 20:54:08 +00001201- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1209- Implement PEP 378, Format Specifier for Thousands Separator, for
1210 floats.
1211
Mark Dickinson3370cce2009-04-17 22:40:53 +00001212- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001213 1e11, not 1e12. This avoids printing 13 significant digits in
1214 situations where only 12 of them are correct. Example problem
1215 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1216 long time.)
1217
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001218- Issue #1580: On most platforms, use a 'short' float repr: for a
1219 finite float x, repr(x) now outputs a string based on the shortest
1220 sequence of decimal digits that rounds to x. Previous behaviour was
1221 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001222 Another minor difference is that the new repr switches to
1223 exponential notation at 1e16 instead of the previous 1e17; this
1224 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001225
1226 There's a new sys attribute sys.float_repr_style, which takes
1227 the value 'short' to indicate that we're using short float repr,
1228 and 'legacy' if the short float repr isn't available for one
1229 reason or another.
1230
1231 The float repr change involves incorporating David Gay's 'perfect
1232 rounding' code into the Python core (it's in Python/dtoa.c). As a
1233 secondary consequence, all string-to-float and float-to-string
1234 conversions (including all float formatting operations) will be
1235 correctly rounded on these platforms.
1236
1237 See issue 1580 discussions for details of platforms for which
1238 this change does not apply.

1241
Georg Brandlabc38772009-04-12 15:51:51 +00001242- The string.maketrans() function is deprecated; there is a new static method
1243 maketrans() on the bytes and bytearray classes. This removes confusion about
1244 the types string.maketrans() is supposed to work with, and mirrors the
1245 methods available on the str class.

1412 untrackable objects are not tracked by the garbage collector. This can
1413 reduce the size of collections and therefore the garbage collection overhead
1414 on long-running programs, depending on their particular use of datatypes.

1483
Lars Gustäbel42e00912009-03-22 20:34:29 +00001484- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1485 forever on incomplete input. That caused tarfile.open() to hang when used
1486 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

1535 rotating the object pointer by 4 bits to the right.
1536
Mark Dickinson87ec0852009-02-09 17:15:59 +00001537- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1538 it now forces its argument to double before testing for infinity.
1539
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001540- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001549
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001550- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001551 were suppressing all exceptions. These include list() and bytearray().

1555
Antoine Pitroub52ec782009-01-25 16:34:23 +00001556- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1557 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1558 evaluation loop is compiled with a new dispatch mechanism which gives
1559 speedups of up to 20%, depending on the system, on various benchmarks.
1560
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001561- Issue #4874: Most builtin decoders now reject unicode input.

1567
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001568- Issue #4838: When a module is deallocated, free the memory backing the
1569 optional module state data.
1570
Mark Dickinson8055afd2009-01-17 10:04:45 +00001571- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1572 type to (void *).
1573
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001574- Issue #4935: The overflow checking code in the expandtabs() method common
1575 to str, bytes and bytearray could be optimized away by the compiler, letting
1576 the interpreter segfault instead of raising an error.
1577
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001578- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1579 __next__ method.
1580
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001581- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1582 function no longer attempt to call the __long__ slot to convert an object
1583 to an integer. Only the __int__ and __trunc__ slots are examined.
1584
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001585- Issue #4893: Use NT threading on CE.
1586

1588
Antoine Pitrouab868312009-01-10 15:40:25 +00001589- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1590 common cases are optimized thanks to a dedicated fast path and a moderate
1591 amount of loop unrolling.
1592
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001593- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1594 collecting the oldest generation) so that allocating lots of objects without
1595 destroying them does not show quadratic performance. Based on a proposal by
1596 Martin von Löwis at
1597 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1598
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001599- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001600 having been closed (for instance, a read() call could return some
1601 previously buffered data). Patch by Dmitry Vasiliev.
1602
Antoine Pitrou05608432009-01-09 18:53:14 +00001603- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1604 flag to work properly. Furthermore, when specifying -u, the text stdout
1605 and stderr streams have line-by-line buffering enabled (the default being
1606 to buffer arbitrary chunks of data).
1607
Raymond Hettinger35631532009-01-09 03:58:09 +00001608- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1609 instead of ints (reducing its size from 4 to 8 times thereby reducing
1610 Python's overall memory).
1611
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001612- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1613 an existing .py counterpart, override the co_filename attributes of all
1614 code objects if the original filename is obsolete (which can happen if the
1615 file has been renamed, moved, or if it is accessed through different paths).
1616 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1617
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001618- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1619 one byte. Also fixes the meaning of len() so that it returns the number of
1620 items, rather than the size in bytes.
1621
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001622- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1623
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001624- Issue #4747: When the terminal does not use utf-8, executing a script with
1625 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1626
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001627- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001628 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001629
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001630- Issue #3680: Reference cycles created through a dict, set or deque iterator
1631 did not get collected.
1632
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001633- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1634 where the tp_hash and tp_dict slots are both NULL.
1635
Georg Brandlccc47b62008-12-28 11:44:14 +00001636- Issue #4759: None is now allowed as the first argument of
1637 bytearray.translate(). It was always allowed for bytes.translate().
1638
Skip Montanaro80072cb2008-12-23 03:51:14 +00001639- Added test case to ensure attempts to read from a file opened for writing
1640 fail.
1641
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001642- Issue #3106: Speedup some comparisons (str/str and int/int).

1646
Antoine Pitrou621601a2008-12-17 23:18:19 +00001647- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1648 print elapsed times, not only when some objects are uncollectable /
1649 unreachable. Original patch by Neil Schemenauer.
1650
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001651- Issue #3439: Add a bit_length method to int.
1652
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001653- Issue #2173: When getting device encoding, check that return value of
1654 nl_langinfo is not the empty string. This was causing silent build
1655 failures on OS X.
1656
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001657- Issue #4597: Fixed several opcodes that weren't always propagating
1658 exceptions.
1659
1660- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001661 context manager returns a value that cannot be converted to a bool.
1662
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001663- Issue #4445: Replace "sizeof(PyBytesObject)" with
1664 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1665 bytes instances. On a typical machine this saves 3 bytes of memory
1666 (on average) per allocation of a bytes instance.
1667
Christian Heimesa872de52008-12-05 08:26:55 +00001668- Issue #4533: File read operation was dreadfully slow due to a slowly
1669 growing read buffer. Fixed by using the same growth rate algorithm as
1670 Python 2.x.
1671
Antoine Pitrou5504e892008-12-06 21:27:53 +00001672- Issue #4509: Various issues surrounding resize of bytearray objects to
1673 which there are buffer exports (e.g. memoryview instances).
1674
Georg Brandlf9734072008-12-07 15:30:06 +00001675- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1676 method on file objects with closefd=False. The file descriptor is still
1677 kept open but the file object behaves like a closed file. The ``FileIO``
1678 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001679
Antoine Pitroubc420402008-12-07 20:14:49 +00001680- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1686
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001687- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1688 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1689 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1690 of using the replace error handler in PyUnicode_DecodeUTF8().
