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

Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000315- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
316 in XML processing instructions and comments. These raw characters are
317 allowed by the XML specification, and are necessary when outputting e.g.
318 PHP code in a processing instruction. Patch by Neil Muller.
319
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000320- Issue #6233: ElementTree failed converting unicode characters to XML

330 type is specified. Patch by Brian Curtin.
331
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000332- Issue #6939: Fix file I/O objects in the `io` module to keep the original
333 file position when calling `truncate()`. It would previously change the
334 file position to the given argument, which goes against the tradition of
335 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
336
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000337- Issue #7610: Reworked implementation of the internal
338 :class:`zipfile.ZipExtFile` class used to represent files stored inside
339 an archive. The new implementation is significantly faster and can
340 be wrapped in a :class:`io.BufferedReader` object for more speedups.
341 It also solves an issue where interleaved calls to `read()` and
342 `readline()` give wrong results. Patch by Nir Aides.
343
Jesse Noller1f0b6582010-01-27 03:36:01 +0000344- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

346 the worker before that worker is terminated, and a new one created to
347 replace it.

504
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000505- Issue #6816: runpy now provides a run_path function that allows Python code
506 to execute file paths that refer to source or compiled Python files as well
507 as zipfiles, directories and other valid sys.path entries that contain a
508 __main__.py file. This allows applications that run other Python scripts to
509 support the same flexibility as the CPython command line itself.
510
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000511- Issue #7318: multiprocessing now uses a timeout when it fails to establish
512 a connection with another process, rather than looping endlessly. The

546 a modification is done through it. This fixes inconsistencies and test
547 failures on systems with slightly bogus mtime behaviour.
548
Gregory P. Smith50467882009-11-01 18:42:17 +0000549- Issue #7246 & Issue #7208: getpass now properly flushes input before
550 reading from stdin so that existing input does not confuse it and

689
Brett Cannon64ef00f2009-07-20 03:19:18 +0000690- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

834 filesystem encoding.
835
R. David Murray378c0cf2010-02-24 01:46:21 +0000836- Issue #6292: for the moment at least, the test suite runs cleanly if python

850
R. David Murray445448c2009-12-20 17:28:31 +0000851- Issue #7376: instead of running a self-test (which was failing) when called

861 user running the tests.
862
R. David Murray35768ad2009-11-15 00:23:21 +0000863- Issue #7324: add a sanity check to regrtest argument parsing to

868
Antoine Pitrou060cee22009-11-13 16:29:04 +0000869- Issue #6551: test_zipimport could import and then destroy some modules of
870 the encodings package, which would make other tests fail further down
871 the road because the internally cached encoders and decoders would point
872 to empty global variables.
873
Antoine Pitrou941ee882009-11-11 20:59:38 +0000874- Issue #7295: Do not use a hardcoded file name in test_tarfile.

888 leak-chasing test runs give sensible results. The previous method of
889 reaping threads could return successfully while some Thread objects were
890 still referenced. This also introduces a new private function:
891 :func:`_thread._count()`.
892
R. David Murray27144602009-10-19 15:26:16 +0000893- Issue #7151: fixed regrtest -j so that output to stderr from a test no

895
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000896- Issue #7055: test___all__ now greedily detects all modules which have an

1099 than an int, which makes some operations possible under 64-bit Linux (e.g.

Mark Dickinson865e01a2009-05-07 16:37:01 +00001180- Issue #5914: Add new C API function PyOS_string_to_double, and
1181 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1182
Eric Smith741191f2009-05-06 13:08:15 +00001183- Issue #3382: float.__format__, complex.__format__, and %-formatting
1184 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1185 affects nan -> NAN and inf -> INF.
1186

Eric Smith63376222009-05-05 14:04:18 +00001191- Issue #5920: For float.__format__, change the behavior with the
1192 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1193 to be like 'g' but with at least one decimal point and with a
1194 default precision of 12. Previously, the behavior the same but with
1195 a default precision of 6. This more closely matches str(), and
1196 reduces surprises when adding alignment flags to the empty
1197 presentation type. This also affects the new complex.__format__ in
1198 the same way.

1212 received a new method, detach(). detach() disconnects the underlying stream
1213 from the buffer or text IO and returns it.
1214
Mark Dickinson33841c32009-05-01 15:37:04 +00001215- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1216 floats with absolute value over 1e50. Also remove length
1217 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Eric Smith741191f2009-05-06 13:08:15 +00001220- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001221 format(complex(1, 2./3), '.5') now produces a sensible result.

Mark Dickinsond3ca5572009-04-29 18:47:07 +00001223- Issue #5864: Fix empty format code formatting for floats so that it
1224 never gives more than the requested number of significant digits.

1238
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001239- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001240
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001241- Issue #1869 (and many duplicates): make round(x, n) correctly
1242 rounded for a float x, by using the decimal <-> binary conversions
1243 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1244 consistently agrees with format(x, '.2f').
1245
Benjamin Petersonae937c02009-04-18 20:54:08 +00001246- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1248
Eric Smith0923d1d2009-04-16 20:16:10 +00001249- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1250
Eric Smith35e84722009-04-16 20:21:28 +00001251- Issue #5515: str.format() type 'n' combined with commas and leading
1252 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001253
1254- Implement PEP 378, Format Specifier for Thousands Separator, for
1255 floats.
1256
Mark Dickinson3370cce2009-04-17 22:40:53 +00001257- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001258 1e11, not 1e12. This avoids printing 13 significant digits in
1259 situations where only 12 of them are correct. Example problem
1260 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1261 long time.)
1262
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001263- Issue #1580: On most platforms, use a 'short' float repr: for a
1264 finite float x, repr(x) now outputs a string based on the shortest
1265 sequence of decimal digits that rounds to x. Previous behaviour was
1266 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001267 Another minor difference is that the new repr switches to
1268 exponential notation at 1e16 instead of the previous 1e17; this
1269 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001270
1271 There's a new sys attribute sys.float_repr_style, which takes
1272 the value 'short' to indicate that we're using short float repr,
1273 and 'legacy' if the short float repr isn't available for one
1274 reason or another.
1275
1276 The float repr change involves incorporating David Gay's 'perfect
1277 rounding' code into the Python core (it's in Python/dtoa.c). As a
1278 secondary consequence, all string-to-float and float-to-string
1279 conversions (including all float formatting operations) will be
1280 correctly rounded on these platforms.
1281
1282 See issue 1580 discussions for details of platforms for which
1283 this change does not apply.
1284
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001285- Issue #5759: float() didn't call __float__ on str subclasses.
1286
Georg Brandlabc38772009-04-12 15:51:51 +00001287- The string.maketrans() function is deprecated; there is a new static method
1288 maketrans() on the bytes and bytearray classes. This removes confusion about
1289 the types string.maketrans() is supposed to work with, and mirrors the
1290 methods available on the str class.
1291
R. David Murraydc6da8a2009-04-09 22:16:43 +00001292- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1457 untrackable objects are not tracked by the garbage collector. This can
1458 reduce the size of collections and therefore the garbage collection overhead
1459 on long-running programs, depending on their particular use of datatypes.

1524 (typically /dev/zero under Unix) could crash the interpreter.
1525
Benjamin Peterson59406a92009-03-26 17:10:29 +00001526- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

1528
Lars Gustäbel42e00912009-03-22 20:34:29 +00001529- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1530 forever on incomplete input. That caused tarfile.open() to hang when used
1531 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1532 partial bzip2 compressed data.
1533
Mark Dickinson79f52032009-03-17 23:12:51 +00001534- Issue #2110: Add support for thousands separator and 'n' type

1552 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001553 struct.error instead of returning b'\xff\xff\xff\xff'. The
1554 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1555 have been removed from the struct module.

1574 contained non ascii character on windows.
1575
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001576- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1577 source has already been decoded into str.
1578
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001579- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1580 rotating the object pointer by 4 bits to the right.
1581
Mark Dickinson87ec0852009-02-09 17:15:59 +00001582- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1583 it now forces its argument to double before testing for infinity.
1584
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001585- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1586 returns a non-number type.
1587
Benjamin Peterson87618552009-02-08 15:00:52 +00001588- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001594
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001595- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001596 were suppressing all exceptions. These include list() and bytearray().
1597
Mark Dickinson1124e712009-01-28 21:25:58 +00001598- Issue #4707: round(x, n) now returns an integer if x is an integer.
1599 Previously it returned a float.
1600
Antoine Pitroub52ec782009-01-25 16:34:23 +00001601- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1602 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1603 evaluation loop is compiled with a new dispatch mechanism which gives
1604 speedups of up to 20%, depending on the system, on various benchmarks.
1605
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001606- Issue #4874: Most builtin decoders now reject unicode input.

1609 from a string.
1610
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001611- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1612
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001613- Issue #4838: When a module is deallocated, free the memory backing the
1614 optional module state data.
1615
Mark Dickinson8055afd2009-01-17 10:04:45 +00001616- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1617 type to (void *).
1618
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001619- Issue #4935: The overflow checking code in the expandtabs() method common
1620 to str, bytes and bytearray could be optimized away by the compiler, letting
1621 the interpreter segfault instead of raising an error.
1622
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001623- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1624 __next__ method.
1625
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001626- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1627 function no longer attempt to call the __long__ slot to convert an object
1628 to an integer. Only the __int__ and __trunc__ slots are examined.
1629
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001630- Issue #4893: Use NT threading on CE.
1631
Martin v. Löwisec59d042009-01-12 07:59:10 +00001632- Issue #4915: Port sysmodule to Windows CE.
1633
Antoine Pitrouab868312009-01-10 15:40:25 +00001634- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1635 common cases are optimized thanks to a dedicated fast path and a moderate
1636 amount of loop unrolling.
1637
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001638- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1639 collecting the oldest generation) so that allocating lots of objects without
1640 destroying them does not show quadratic performance. Based on a proposal by
1641 Martin von Löwis at
1642 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1643
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001644- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001645 having been closed (for instance, a read() call could return some
1646 previously buffered data). Patch by Dmitry Vasiliev.
1647
Antoine Pitrou05608432009-01-09 18:53:14 +00001648- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1649 flag to work properly. Furthermore, when specifying -u, the text stdout
1650 and stderr streams have line-by-line buffering enabled (the default being
1651 to buffer arbitrary chunks of data).
1652
Raymond Hettinger35631532009-01-09 03:58:09 +00001653- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1654 instead of ints (reducing its size from 4 to 8 times thereby reducing
1655 Python's overall memory).
1656
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001657- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1658 an existing .py counterpart, override the co_filename attributes of all
1659 code objects if the original filename is obsolete (which can happen if the
1660 file has been renamed, moved, or if it is accessed through different paths).
1661 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1662
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001663- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1664 one byte. Also fixes the meaning of len() so that it returns the number of
1665 items, rather than the size in bytes.
1666
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001667- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1668
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001669- Issue #4747: When the terminal does not use utf-8, executing a script with
1670 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1671
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001672- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001673 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001674
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001675- Issue #3680: Reference cycles created through a dict, set or deque iterator
1676 did not get collected.
1677
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001678- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1679 where the tp_hash and tp_dict slots are both NULL.
1680
Georg Brandlccc47b62008-12-28 11:44:14 +00001681- Issue #4759: None is now allowed as the first argument of
1682 bytearray.translate(). It was always allowed for bytes.translate().
1683
Skip Montanaro80072cb2008-12-23 03:51:14 +00001684- Added test case to ensure attempts to read from a file opened for writing
1685 fail.
1686
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001687- Issue #3106: Speedup some comparisons (str/str and int/int).

1690 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1691
Antoine Pitrou621601a2008-12-17 23:18:19 +00001692- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1693 print elapsed times, not only when some objects are uncollectable /
1694 unreachable. Original patch by Neil Schemenauer.
1695
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001696- Issue #3439: Add a bit_length method to int.
1697
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001698- Issue #2173: When getting device encoding, check that return value of
1699 nl_langinfo is not the empty string. This was causing silent build
1700 failures on OS X.
1701
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001702- Issue #4597: Fixed several opcodes that weren't always propagating
1703 exceptions.
1704
1705- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001706 context manager returns a value that cannot be converted to a bool.
1707
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001708- Issue #4445: Replace "sizeof(PyBytesObject)" with
1709 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1710 bytes instances. On a typical machine this saves 3 bytes of memory
1711 (on average) per allocation of a bytes instance.
1712
Christian Heimesa872de52008-12-05 08:26:55 +00001713- Issue #4533: File read operation was dreadfully slow due to a slowly
1714 growing read buffer. Fixed by using the same growth rate algorithm as
1715 Python 2.x.
1716
Antoine Pitrou5504e892008-12-06 21:27:53 +00001717- Issue #4509: Various issues surrounding resize of bytearray objects to
1718 which there are buffer exports (e.g. memoryview instances).
1719
Georg Brandlf9734072008-12-07 15:30:06 +00001720- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1721 method on file objects with closefd=False. The file descriptor is still
1722 kept open but the file object behaves like a closed file. The ``FileIO``
1723 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001724
Antoine Pitroubc420402008-12-07 20:14:49 +00001725- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1731
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001732- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1733 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1734 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1735 of using the replace error handler in PyUnicode_DecodeUTF8().
