13-----------------
14
Victor Stinner6aa278e2010-03-03 00:18:49 +000015- Issue #7820: The parser tokenizer restores all bytes in the right if
16 the BOM check fails.
17
Benjamin Peterson23e018a2010-02-27 17:40:01 +000018- Handle errors from looking up __prepare__ correctly.
19

21 in Modules/_ctypes/callproc.c.
22
Eric Smith0facd772010-02-24 15:42:29 +000023- Issue #7309: Fix unchecked attribute access when converting
24 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
25 strings.
26
Eric Smithabb28c62010-02-23 00:22:24 +000027- Issue #6902: Fix problem with built-in types format incorrectly with
28 0 padding.
29
Eric Smith4e260c52010-02-22 18:54:44 +000030- Issue #7988: Fix default alignment to be right aligned for
31 complex.__format__. Now it matches other numeric types.
32
Eric Smith68af50b2010-02-22 14:58:30 +000033- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
34 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
35 and PyOS_string_to_double instead. See issue #5835 for the original
36 deprecations.
37
Antoine Pitrou05b7c562010-02-02 22:47:00 +000038- Issue #7385: Fix a crash in `MemoryView_FromObject` when
39 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
40
Mark Dickinsonbc099642010-01-29 17:27:24 +000041- Issue #7788: Fix an interpreter crash produced by deleting a list
42 slice with very large step value.
43
Eric Smithf7bb5782010-01-27 00:44:57 +000044- Issue #7766: Change sys.getwindowsversion() return value to a named
45 tuple and add the additional members returned in an OSVERSIONINFOEX
46 structure. The new members are service_pack_major, service_pack_minor,
47 suite_mask, and product_type.
48
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000049- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
50 could crash in many places because of the PyByteArray_AS_STRING() macro
51 returning NULL. The macro now returns a statically allocated empty
52 string instead.
53
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000054- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
55 where the right hand operand is a set of constants, by turning the set into
56 a frozenset and pre-building it as a constant. The comparison operation
57 is made against the constant instead of building a new set each time it is
58 executed (a similar optimization already existed which turned a list of
59 constants into a pre-built tuple). Patch and additional tests by Dave
60 Malcolm.
61
Antoine Pitrouf2c54842010-01-13 08:07:53 +000062- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
63 methods of bytes, bytearray and unicode objects by using a common
64 implementation based on stringlib's fast search. Patch by Florent Xicluna.
65
Mark Dickinson45b63652010-01-16 18:10:25 +000066- Issue #7632: Fix various str -> float conversion bugs present in 2.7
67 alpha 2, including: (1) a serious 'wrong output' bug that could
68 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
69 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000070 strings corresponding to subnormal values, (3) a memory leak for
71 some values large enough to cause overflow, and (4) a number of
72 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000073
Benjamin Petersonaea44282010-01-04 01:10:28 +000074- The __complex__ method is now looked up on the class of instances to make it
75 consistent with other special methods.
76

78 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
79
Benjamin Petersond12362a2009-12-30 19:44:54 +000080- Issue #7604: Deleting an unset slotted attribute did not raise an
81 AttributeError.
82
Mark Dickinson9ab44b52009-12-30 16:22:49 +000083- Issue #7534: Fix handling of IEEE specials (infinities, nans,
84 negative zero) in ** operator. The behaviour now conforms to that
85 described in C99 Annex F.
86
Mark Dickinsoncbb62742009-12-27 15:09:50 +000087- Issue #1811: improve accuracy and cross-platform consistency for
88 true division of integers: the result of a/b is now correctly
89 rounded for ints a and b (at least on IEEE 754 platforms), and in
90 particular does not depend on the internal representation of an int.
91
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000092- Issue #6834: replace the implementation for the 'python' and 'pythonw'
93 executables on OSX.
94
95 These executables now work properly with the arch(1) command:
96 ``arch -ppc python`` will start a universal binary version of python
97 in PPC mode (unlike previous releases).
98
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000099- Issue #7466: segmentation fault when the garbage collector is called
100 in the middle of populating a tuple. Patch by Florent Xicluna.
101

103 with invalid values.
104
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000105- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
106 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).

112
Mark Dickinson6f1d0492009-11-15 13:58:49 +0000113- Issue #6970: Remove redundant calls when comparing objects that don't
114 implement the relevant rich comparison methods.
115
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000116- Issue #7298: fixes for range and reversed(range(...)). Iteration
117 over range(a, b, c) incorrectly gave an empty iterator when a, b and
118 c fit in C long but the length of the range did not. Also fix
119 several cases where reversed(range(a, b, c)) gave wrong results, and
120 fix a refleak for reversed(range(a, b, c)) with large arguments.
121
Raymond Hettingerfc438512009-11-01 20:55:33 +0000122- Issue #7244: itertools.izip_longest() no longer ignores exceptions

328
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000329- Issue #6939: Fix file I/O objects in the `io` module to keep the original
330 file position when calling `truncate()`. It would previously change the
331 file position to the given argument, which goes against the tradition of
332 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
333
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000334- Issue #7610: Reworked implementation of the internal
335 :class:`zipfile.ZipExtFile` class used to represent files stored inside
336 an archive. The new implementation is significantly faster and can
337 be wrapped in a :class:`io.BufferedReader` object for more speedups.
338 It also solves an issue where interleaved calls to `read()` and
339 `readline()` give wrong results. Patch by Nir Aides.
340
Jesse Noller1f0b6582010-01-27 03:36:01 +0000341- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

501
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000502- Issue #6816: runpy now provides a run_path function that allows Python code
503 to execute file paths that refer to source or compiled Python files as well
504 as zipfiles, directories and other valid sys.path entries that contain a
505 __main__.py file. This allows applications that run other Python scripts to
506 support the same flexibility as the CPython command line itself.
507
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000508- Issue #7318: multiprocessing now uses a timeout when it fails to establish

544 failures on systems with slightly bogus mtime behaviour.
545
Gregory P. Smith50467882009-11-01 18:42:17 +0000546- Issue #7246 & Issue #7208: getpass now properly flushes input before
547 reading from stdin so that existing input does not confuse it and

831 filesystem encoding.
832
R. David Murray378c0cf2010-02-24 01:46:21 +0000833- Issue #6292: for the moment at least, the test suite runs cleanly if python

847
R. David Murray445448c2009-12-20 17:28:31 +0000848- Issue #7376: instead of running a self-test (which was failing) when called

852

857 file in the Lib/test directory, which might be read-only for the
858 user running the tests.
859
R. David Murray35768ad2009-11-15 00:23:21 +0000860- Issue #7324: add a sanity check to regrtest argument parsing to

864 a test fails. Can be combined with -j.
865
Antoine Pitrou060cee22009-11-13 16:29:04 +0000866- Issue #6551: test_zipimport could import and then destroy some modules of
867 the encodings package, which would make other tests fail further down
868 the road because the internally cached encoders and decoders would point
869 to empty global variables.
870
Antoine Pitrou941ee882009-11-11 20:59:38 +0000871- Issue #7295: Do not use a hardcoded file name in test_tarfile.

885 leak-chasing test runs give sensible results. The previous method of
886 reaping threads could return successfully while some Thread objects were
887 still referenced. This also introduces a new private function:
888 :func:`_thread._count()`.
889
R. David Murray27144602009-10-19 15:26:16 +0000890- Issue #7151: fixed regrtest -j so that output to stderr from a test no

892
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000893- Issue #7055: test___all__ now greedily detects all modules which have an

904 object bytecode.
905
Brett Cannonb49c70c2009-07-15 04:08:33 +0000906- Removed importlib's custom test discovery code and switched to

1096 than an int, which makes some operations possible under 64-bit Linux (e.g.

Mark Dickinson865e01a2009-05-07 16:37:01 +00001177- Issue #5914: Add new C API function PyOS_string_to_double, and
1178 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1179
Eric Smith741191f2009-05-06 13:08:15 +00001180- Issue #3382: float.__format__, complex.__format__, and %-formatting
1181 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1182 affects nan -> NAN and inf -> INF.

1190 to be like 'g' but with at least one decimal point and with a
1191 default precision of 12. Previously, the behavior the same but with
1192 a default precision of 6. This more closely matches str(), and
1193 reduces surprises when adding alignment flags to the empty
1194 presentation type. This also affects the new complex.__format__ in
1195 the same way.
1196
Martin v. Löwis011e8422009-05-05 04:43:17 +00001197- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1209 received a new method, detach(). detach() disconnects the underlying stream
1210 from the buffer or text IO and returns it.
1211
Mark Dickinson33841c32009-05-01 15:37:04 +00001212- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1213 floats with absolute value over 1e50. Also remove length
1214 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Eric Smith58a42242009-04-30 01:00:33 +00001218 format(complex(1, 2./3), '.5') now produces a sensible result.
1219
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001220- Issue #5864: Fix empty format code formatting for floats so that it
1221 never gives more than the requested number of significant digits.
1222
Eric Smith6dc46f52009-04-27 20:39:49 +00001223- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1229 titlecase, but not their own uppercase.
1230
Benjamin Peterson193152c2009-04-25 01:08:45 +00001231- Issue #5283: Setting __class__ in __del__ caused a segfault.
1232
Mark Dickinsonad476da2009-04-23 19:14:16 +00001233- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1234 z involves nans, infs or negative zeros.
1235
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001236- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001237
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001238- Issue #1869 (and many duplicates): make round(x, n) correctly
1239 rounded for a float x, by using the decimal <-> binary conversions
1240 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1241 consistently agrees with format(x, '.2f').
1242
Benjamin Petersonae937c02009-04-18 20:54:08 +00001243- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1244 some builtin types.
1245
Eric Smith0923d1d2009-04-16 20:16:10 +00001246- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1247
Eric Smith35e84722009-04-16 20:21:28 +00001248- Issue #5515: str.format() type 'n' combined with commas and leading
1249 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001250
1251- Implement PEP 378, Format Specifier for Thousands Separator, for
1252 floats.
1253
Mark Dickinson3370cce2009-04-17 22:40:53 +00001254- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001255 1e11, not 1e12. This avoids printing 13 significant digits in
1256 situations where only 12 of them are correct. Example problem
1257 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1258 long time.)
1259
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001260- Issue #1580: On most platforms, use a 'short' float repr: for a
1261 finite float x, repr(x) now outputs a string based on the shortest
1262 sequence of decimal digits that rounds to x. Previous behaviour was
1263 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001264 Another minor difference is that the new repr switches to
1265 exponential notation at 1e16 instead of the previous 1e17; this
1266 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001267
1268 There's a new sys attribute sys.float_repr_style, which takes
1269 the value 'short' to indicate that we're using short float repr,
1270 and 'legacy' if the short float repr isn't available for one
1271 reason or another.
1272
1273 The float repr change involves incorporating David Gay's 'perfect
1274 rounding' code into the Python core (it's in Python/dtoa.c). As a
1275 secondary consequence, all string-to-float and float-to-string
1276 conversions (including all float formatting operations) will be
1277 correctly rounded on these platforms.
1278
1279 See issue 1580 discussions for details of platforms for which
1280 this change does not apply.
1281
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001282- Issue #5759: float() didn't call __float__ on str subclasses.
1283
Georg Brandlabc38772009-04-12 15:51:51 +00001284- The string.maketrans() function is deprecated; there is a new static method
1285 maketrans() on the bytes and bytearray classes. This removes confusion about
1286 the types string.maketrans() is supposed to work with, and mirrors the
1287 methods available on the str class.
1288
R. David Murraydc6da8a2009-04-09 22:16:43 +00001289- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1294
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001295- Issue #3739: The unicode-internal encoder now reports the number of characters

1454 untrackable objects are not tracked by the garbage collector. This can
1455 reduce the size of collections and therefore the garbage collection overhead
1456 on long-running programs, depending on their particular use of datatypes.

1521 (typically /dev/zero under Unix) could crash the interpreter.
1522
Benjamin Peterson59406a92009-03-26 17:10:29 +00001523- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

1525
Lars Gustäbel42e00912009-03-22 20:34:29 +00001526- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1527 forever on incomplete input. That caused tarfile.open() to hang when used
1528 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1529 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001550 struct.error instead of returning b'\xff\xff\xff\xff'. The
1551 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

1571 contained non ascii character on windows.
1572
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001573- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1574 source has already been decoded into str.
1575
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001576- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1577 rotating the object pointer by 4 bits to the right.
1578
Mark Dickinson87ec0852009-02-09 17:15:59 +00001579- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1580 it now forces its argument to double before testing for infinity.
1581
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001582- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1583 returns a non-number type.
1584
Benjamin Peterson87618552009-02-08 15:00:52 +00001585- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001591
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001592- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001593 were suppressing all exceptions. These include list() and bytearray().
1594
Mark Dickinson1124e712009-01-28 21:25:58 +00001595- Issue #4707: round(x, n) now returns an integer if x is an integer.
1596 Previously it returned a float.
1597
Antoine Pitroub52ec782009-01-25 16:34:23 +00001598- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1599 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1600 evaluation loop is compiled with a new dispatch mechanism which gives
1601 speedups of up to 20%, depending on the system, on various benchmarks.
1602
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001603- Issue #4874: Most builtin decoders now reject unicode input.

1606 from a string.
1607
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001608- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1609
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001610- Issue #4838: When a module is deallocated, free the memory backing the
1611 optional module state data.
1612
Mark Dickinson8055afd2009-01-17 10:04:45 +00001613- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1614 type to (void *).
1615
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001616- Issue #4935: The overflow checking code in the expandtabs() method common
1617 to str, bytes and bytearray could be optimized away by the compiler, letting
1618 the interpreter segfault instead of raising an error.
1619
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001620- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1621 __next__ method.
1622
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001623- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1624 function no longer attempt to call the __long__ slot to convert an object
1625 to an integer. Only the __int__ and __trunc__ slots are examined.
1626
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001627- Issue #4893: Use NT threading on CE.
1628
Martin v. Löwisec59d042009-01-12 07:59:10 +00001629- Issue #4915: Port sysmodule to Windows CE.
1630
Antoine Pitrouab868312009-01-10 15:40:25 +00001631- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1632 common cases are optimized thanks to a dedicated fast path and a moderate
1633 amount of loop unrolling.
1634
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001635- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1636 collecting the oldest generation) so that allocating lots of objects without
1637 destroying them does not show quadratic performance. Based on a proposal by
1638 Martin von Löwis at
1639 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1640
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001641- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001642 having been closed (for instance, a read() call could return some
1643 previously buffered data). Patch by Dmitry Vasiliev.
1644
Antoine Pitrou05608432009-01-09 18:53:14 +00001645- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1646 flag to work properly. Furthermore, when specifying -u, the text stdout
1647 and stderr streams have line-by-line buffering enabled (the default being
1648 to buffer arbitrary chunks of data).
1649
Raymond Hettinger35631532009-01-09 03:58:09 +00001650- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1651 instead of ints (reducing its size from 4 to 8 times thereby reducing
1652 Python's overall memory).
1653
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001654- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1655 an existing .py counterpart, override the co_filename attributes of all
1656 code objects if the original filename is obsolete (which can happen if the
1657 file has been renamed, moved, or if it is accessed through different paths).
1658 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1659
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001660- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1661 one byte. Also fixes the meaning of len() so that it returns the number of
1662 items, rather than the size in bytes.
1663
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001664- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1665
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001666- Issue #4747: When the terminal does not use utf-8, executing a script with
1667 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1668
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001669- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001670 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001671
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001672- Issue #3680: Reference cycles created through a dict, set or deque iterator
1673 did not get collected.
1674
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001675- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1676 where the tp_hash and tp_dict slots are both NULL.
1677
Georg Brandlccc47b62008-12-28 11:44:14 +00001678- Issue #4759: None is now allowed as the first argument of
1679 bytearray.translate(). It was always allowed for bytes.translate().
1680
Skip Montanaro80072cb2008-12-23 03:51:14 +00001681- Added test case to ensure attempts to read from a file opened for writing
1682 fail.
1683
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001684- Issue #3106: Speedup some comparisons (str/str and int/int).

1687 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1688
Antoine Pitrou621601a2008-12-17 23:18:19 +00001689- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1690 print elapsed times, not only when some objects are uncollectable /
1691 unreachable. Original patch by Neil Schemenauer.
1692
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001693- Issue #3439: Add a bit_length method to int.
1694
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001695- Issue #2173: When getting device encoding, check that return value of
1696 nl_langinfo is not the empty string. This was causing silent build
1697 failures on OS X.
1698
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001699- Issue #4597: Fixed several opcodes that weren't always propagating
1700 exceptions.
1701
1702- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001703 context manager returns a value that cannot be converted to a bool.
1704
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001705- Issue #4445: Replace "sizeof(PyBytesObject)" with
1706 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1707 bytes instances. On a typical machine this saves 3 bytes of memory
1708 (on average) per allocation of a bytes instance.
1709
Christian Heimesa872de52008-12-05 08:26:55 +00001710- Issue #4533: File read operation was dreadfully slow due to a slowly
1711 growing read buffer. Fixed by using the same growth rate algorithm as
1712 Python 2.x.
1713
Antoine Pitrou5504e892008-12-06 21:27:53 +00001714- Issue #4509: Various issues surrounding resize of bytearray objects to
1715 which there are buffer exports (e.g. memoryview instances).
1716
Georg Brandlf9734072008-12-07 15:30:06 +00001717- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1718 method on file objects with closefd=False. The file descriptor is still
1719 kept open but the file object behaves like a closed file. The ``FileIO``
1720 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001721
Antoine Pitroubc420402008-12-07 20:14:49 +00001722- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1728
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001729- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1730 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1731 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1732 of using the replace error handler in PyUnicode_DecodeUTF8().
