12Core and Builtins
13-----------------
14
Benjamin Peterson23e018a2010-02-27 17:40:01 +000015- Handle errors from looking up __prepare__ correctly.
16
Larry Hastings1373a072010-02-24 22:49:58 +000017- Issue #5939: Add additional runtime checking to ensure a valid capsule
18 in Modules/_ctypes/callproc.c.
19
Eric Smith0facd772010-02-24 15:42:29 +000020- Issue #7309: Fix unchecked attribute access when converting
21 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
22 strings.
23
Eric Smithabb28c62010-02-23 00:22:24 +000024- Issue #6902: Fix problem with built-in types format incorrectly with
25 0 padding.
26
Eric Smith4e260c52010-02-22 18:54:44 +000027- Issue #7988: Fix default alignment to be right aligned for
28 complex.__format__. Now it matches other numeric types.
29
Eric Smith68af50b2010-02-22 14:58:30 +000030- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
31 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
32 and PyOS_string_to_double instead. See issue #5835 for the original
33 deprecations.
34
Antoine Pitrou05b7c562010-02-02 22:47:00 +000035- Issue #7385: Fix a crash in `MemoryView_FromObject` when
36 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
37
Mark Dickinsonbc099642010-01-29 17:27:24 +000038- Issue #7788: Fix an interpreter crash produced by deleting a list
39 slice with very large step value.
40
Eric Smithf7bb5782010-01-27 00:44:57 +000041- Issue #7766: Change sys.getwindowsversion() return value to a named
42 tuple and add the additional members returned in an OSVERSIONINFOEX
43 structure. The new members are service_pack_major, service_pack_minor,
44 suite_mask, and product_type.
45
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000046- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
47 could crash in many places because of the PyByteArray_AS_STRING() macro
48 returning NULL. The macro now returns a statically allocated empty
49 string instead.
50
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000051- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
52 where the right hand operand is a set of constants, by turning the set into
53 a frozenset and pre-building it as a constant. The comparison operation
54 is made against the constant instead of building a new set each time it is
55 executed (a similar optimization already existed which turned a list of
56 constants into a pre-built tuple). Patch and additional tests by Dave
57 Malcolm.
58
Antoine Pitrouf2c54842010-01-13 08:07:53 +000059- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
60 methods of bytes, bytearray and unicode objects by using a common
61 implementation based on stringlib's fast search. Patch by Florent Xicluna.
62
Mark Dickinson45b63652010-01-16 18:10:25 +000063- Issue #7632: Fix various str -> float conversion bugs present in 2.7
64 alpha 2, including: (1) a serious 'wrong output' bug that could
65 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
66 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000067 strings corresponding to subnormal values, (3) a memory leak for
68 some values large enough to cause overflow, and (4) a number of
69 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000070
Benjamin Petersonaea44282010-01-04 01:10:28 +000071- The __complex__ method is now looked up on the class of instances to make it
72 consistent with other special methods.
73
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000074- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
75 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
76
Benjamin Petersond12362a2009-12-30 19:44:54 +000077- Issue #7604: Deleting an unset slotted attribute did not raise an
78 AttributeError.
79
Mark Dickinson9ab44b52009-12-30 16:22:49 +000080- Issue #7534: Fix handling of IEEE specials (infinities, nans,
81 negative zero) in ** operator. The behaviour now conforms to that
82 described in C99 Annex F.
83
Mark Dickinsoncbb62742009-12-27 15:09:50 +000084- Issue #1811: improve accuracy and cross-platform consistency for
85 true division of integers: the result of a/b is now correctly
86 rounded for ints a and b (at least on IEEE 754 platforms), and in
87 particular does not depend on the internal representation of an int.
88
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000089- Issue #6834: replace the implementation for the 'python' and 'pythonw'
90 executables on OSX.
91
92 These executables now work properly with the arch(1) command:
93 ``arch -ppc python`` will start a universal binary version of python
94 in PPC mode (unlike previous releases).
95
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000096- Issue #7466: segmentation fault when the garbage collector is called
97 in the middle of populating a tuple. Patch by Florent Xicluna.
98

100 with invalid values.
101
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000102- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
103 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
104

106 on MacOSX 10.6.
107
Philip Jenvey1309adb2009-11-17 03:43:14 +0000108- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
109
Mark Dickinson6f1d0492009-11-15 13:58:49 +0000110- Issue #6970: Remove redundant calls when comparing objects that don't
111 implement the relevant rich comparison methods.
112
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000113- Issue #7298: fixes for range and reversed(range(...)). Iteration
114 over range(a, b, c) incorrectly gave an empty iterator when a, b and
115 c fit in C long but the length of the range did not. Also fix
116 several cases where reversed(range(a, b, c)) gave wrong results, and
117 fix a refleak for reversed(range(a, b, c)) with large arguments.
118
Raymond Hettingerfc438512009-11-01 20:55:33 +0000119- Issue #7244: itertools.izip_longest() no longer ignores exceptions

128
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000129- Support for AtheOS has been completely removed from the code base. It was
130 disabled since Python 3.0.
131
132- Support for several legacy threading libraries has been disabled. These
133 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
134 will be entirely removed in 3.3.

321 type is specified. Patch by Brian Curtin.
322
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000323- Issue #6939: Fix file I/O objects in the `io` module to keep the original
324 file position when calling `truncate()`. It would previously change the
325 file position to the given argument, which goes against the tradition of
326 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
327
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000328- Issue #7610: Reworked implementation of the internal
329 :class:`zipfile.ZipExtFile` class used to represent files stored inside
330 an archive. The new implementation is significantly faster and can
331 be wrapped in a :class:`io.BufferedReader` object for more speedups.
332 It also solves an issue where interleaved calls to `read()` and
333 `readline()` give wrong results. Patch by Nir Aides.
334
Jesse Noller1f0b6582010-01-27 03:36:01 +0000335- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

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

495
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000496- Issue #6816: runpy now provides a run_path function that allows Python code
497 to execute file paths that refer to source or compiled Python files as well
498 as zipfiles, directories and other valid sys.path entries that contain a
499 __main__.py file. This allows applications that run other Python scripts to
500 support the same flexibility as the CPython command line itself.
501
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000502- Issue #7318: multiprocessing now uses a timeout when it fails to establish
503 a connection with another process, rather than looping endlessly. The

537 a modification is done through it. This fixes inconsistencies and test
538 failures on systems with slightly bogus mtime behaviour.
539
Gregory P. Smith50467882009-11-01 18:42:17 +0000540- Issue #7246 & Issue #7208: getpass now properly flushes input before
541 reading from stdin so that existing input does not confuse it and
542 lead to incorrect entry or an IOError. It also properly flushes it
543 afterwards to avoid the terminal echoing the input afterwards on
544 OSes such as Solaris.

680
Brett Cannon64ef00f2009-07-20 03:19:18 +0000681- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

813-----
814
R. David Murray378c0cf2010-02-24 01:46:21 +0000815- Issue #6292: for the moment at least, the test suite runs cleanly if python

821 Thanks to Florent Xicluna who helped with the patch.
822
Mark Dickinsonedff7af2010-02-13 18:34:53 +0000823- Issue #7924: Fix an intermittent 'XXX undetected error' failure in

826
R. David Murraye9e95932010-02-06 05:00:15 +0000827- issue #7728: test_timeout was changed to use test_support.bind_port
828 instead of a hard coded port.
829
R. David Murray445448c2009-12-20 17:28:31 +0000830- Issue #7376: instead of running a self-test (which was failing) when called
831 with no arguments, doctest.py now gives a usage message.
832
R. David Murrayef1992b2009-12-16 15:19:27 +0000833- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
834
R. David Murray596da442009-12-14 23:06:11 +0000835- Issue #7498: test_multiprocessing now uses test.support.find_unused_port

837
R. David Murrayba311052009-12-04 00:09:14 +0000838- Issue #7431: use TESTFN in test_linecache instead of trying to create a
839 file in the Lib/test directory, which might be read-only for the
840 user running the tests.
841
R. David Murray35768ad2009-11-15 00:23:21 +0000842- Issue #7324: add a sanity check to regrtest argument parsing to
843 catch the case of an option with no handler.
844
R. David Murray7dc72cc2009-11-14 16:13:02 +0000845- Issue #7312: Add a -F flag to run the selected tests in a loop until
846 a test fails. Can be combined with -j.
847
Antoine Pitrou060cee22009-11-13 16:29:04 +0000848- Issue #6551: test_zipimport could import and then destroy some modules of
849 the encodings package, which would make other tests fail further down
850 the road because the internally cached encoders and decoders would point
851 to empty global variables.
852
Antoine Pitrou941ee882009-11-11 20:59:38 +0000853- Issue #7295: Do not use a hardcoded file name in test_tarfile.

864 calling methods on the object.
865
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000866- Issue #7222: Make thread "reaping" more reliable so that reference
867 leak-chasing test runs give sensible results. The previous method of
868 reaping threads could return successfully while some Thread objects were
869 still referenced. This also introduces a new private function:
870 :func:`_thread._count()`.
871
R. David Murray27144602009-10-19 15:26:16 +0000872- Issue #7151: fixed regrtest -j so that output to stderr from a test no
873 longer runs the risk of causing the worker thread to fail.
874
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000875- Issue #7055: test___all__ now greedily detects all modules which have an
876 __all__ attribute, rather than using a hardcoded and incomplete list.
877
R. David Murray0bc11ae2009-10-18 22:18:17 +0000878- Issue #7058: Added save/restore for things like sys.argv and cwd to

885 the proper exceptions that should be raised for missing or improper code
886 object bytecode.
887
Brett Cannonb49c70c2009-07-15 04:08:33 +0000888- Removed importlib's custom test discovery code and switched to
889 unittest.TestLoader.discover().

1173 default precision of 12. Previously, the behavior the same but with
1174 a default precision of 6. This more closely matches str(), and
1175 reduces surprises when adding alignment flags to the empty
1176 presentation type. This also affects the new complex.__format__ in
1177 the same way.

1191 received a new method, detach(). detach() disconnects the underlying stream
1192 from the buffer or text IO and returns it.

Mark Dickinson33841c32009-05-01 15:37:04 +00001194- Issue #5859: Remove switch from '%f' to '%g'-style formatting for

Mark Dickinsonad476da2009-04-23 19:14:16 +00001215- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1216 z involves nans, infs or negative zeros.
1217
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001218- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001219
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001220- Issue #1869 (and many duplicates): make round(x, n) correctly
1221 rounded for a float x, by using the decimal <-> binary conversions
1222 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1223 consistently agrees with format(x, '.2f').
1224
Benjamin Petersonae937c02009-04-18 20:54:08 +00001225- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1226 some builtin types.
1227
Eric Smith0923d1d2009-04-16 20:16:10 +00001228- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1229
Eric Smith35e84722009-04-16 20:21:28 +00001230- Issue #5515: str.format() type 'n' combined with commas and leading
1231 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001232
1233- Implement PEP 378, Format Specifier for Thousands Separator, for
1234 floats.
1235
Mark Dickinson3370cce2009-04-17 22:40:53 +00001236- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001237 1e11, not 1e12. This avoids printing 13 significant digits in
1238 situations where only 12 of them are correct. Example problem
1239 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1240 long time.)
1241
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001242- Issue #1580: On most platforms, use a 'short' float repr: for a
1243 finite float x, repr(x) now outputs a string based on the shortest
1244 sequence of decimal digits that rounds to x. Previous behaviour was
1245 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001246 Another minor difference is that the new repr switches to
1247 exponential notation at 1e16 instead of the previous 1e17; this
1248 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001249
1250 There's a new sys attribute sys.float_repr_style, which takes
1251 the value 'short' to indicate that we're using short float repr,
1252 and 'legacy' if the short float repr isn't available for one
1253 reason or another.
1254
1255 The float repr change involves incorporating David Gay's 'perfect
1256 rounding' code into the Python core (it's in Python/dtoa.c). As a
1257 secondary consequence, all string-to-float and float-to-string
1258 conversions (including all float formatting operations) will be
1259 correctly rounded on these platforms.
1260
1261 See issue 1580 discussions for details of platforms for which
1262 this change does not apply.
1263
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001264- Issue #5759: float() didn't call __float__ on str subclasses.
1265
Georg Brandlabc38772009-04-12 15:51:51 +00001266- The string.maketrans() function is deprecated; there is a new static method
1267 maketrans() on the bytes and bytearray classes. This removes confusion about
1268 the types string.maketrans() is supposed to work with, and mirrors the
1269 methods available on the str class.
1270
R. David Murraydc6da8a2009-04-09 22:16:43 +00001271- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1276
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001277- Issue #3739: The unicode-internal encoder now reports the number of characters

1434
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001435- Issue #4688: Add a heuristic so that tuples and dicts containing only
1436 untrackable objects are not tracked by the garbage collector. This can
1437 reduce the size of collections and therefore the garbage collection overhead
1438 on long-running programs, depending on their particular use of datatypes.

1446 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1447 --enable-big-digits option to configure, which overrides the
1448 default. Add sys.int_info structseq to provide information about
1449 the internal format.

Mark Dickinson081dfee2009-03-18 14:47:41 +00001451- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1452 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1453 and sizeof(Py_UNICODE) == 2.
1454
Eric Smith8ec90442009-03-14 12:29:34 +00001455- Issue #5237: Allow auto-numbered fields in str.format(). For

1504
Benjamin Peterson59406a92009-03-26 17:10:29 +00001505- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1506 io.BufferedRandom have been deprecated for removal in Python 3.2.
1507
Lars Gustäbel42e00912009-03-22 20:34:29 +00001508- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1509 forever on incomplete input. That caused tarfile.open() to hang when used
1510 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1511 partial bzip2 compressed data.
1512
Mark Dickinson79f52032009-03-17 23:12:51 +00001513- Issue #2110: Add support for thousands separator and 'n' type

1517 '>' alignment characters.
1518
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00001519- The error detection code in FileIO.close() could fail to reflect the `errno`
1520 value, and report it as -1 instead.
1521

1531 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001532 struct.error instead of returning b'\xff\xff\xff\xff'. The
1533 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1534 have been removed from the struct module.

1553 contained non ascii character on windows.
1554
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001555- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1556 source has already been decoded into str.
1557

1559 rotating the object pointer by 4 bits to the right.
1560
Mark Dickinson87ec0852009-02-09 17:15:59 +00001561- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1562 it now forces its argument to double before testing for infinity.
1563
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001564- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1565 returns a non-number type.
1566
Benjamin Peterson87618552009-02-08 15:00:52 +00001567- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001573
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001574- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001575 were suppressing all exceptions. These include list() and bytearray().
1576
Mark Dickinson1124e712009-01-28 21:25:58 +00001577- Issue #4707: round(x, n) now returns an integer if x is an integer.
1578 Previously it returned a float.
1579
Antoine Pitroub52ec782009-01-25 16:34:23 +00001580- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1581 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1582 evaluation loop is compiled with a new dispatch mechanism which gives
1583 speedups of up to 20%, depending on the system, on various benchmarks.
1584
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001585- Issue #4874: Most builtin decoders now reject unicode input.

1588 from a string.
1589
Benjamin Peterson05e782f2009-01-19 15:15:02 +00001590- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
1591
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001592- Issue #4838: When a module is deallocated, free the memory backing the
1593 optional module state data.
1594
Mark Dickinson8055afd2009-01-17 10:04:45 +00001595- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1596 type to (void *).
1597
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001598- Issue #4935: The overflow checking code in the expandtabs() method common
1599 to str, bytes and bytearray could be optimized away by the compiler, letting
1600 the interpreter segfault instead of raising an error.
1601
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001602- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1603 __next__ method.
1604
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001605- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1606 function no longer attempt to call the __long__ slot to convert an object
1607 to an integer. Only the __int__ and __trunc__ slots are examined.
1608
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001609- Issue #4893: Use NT threading on CE.
1610
Martin v. Löwisec59d042009-01-12 07:59:10 +00001611- Issue #4915: Port sysmodule to Windows CE.
1612
Antoine Pitrouab868312009-01-10 15:40:25 +00001613- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1614 common cases are optimized thanks to a dedicated fast path and a moderate
1615 amount of loop unrolling.
1616
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001617- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1618 collecting the oldest generation) so that allocating lots of objects without
1619 destroying them does not show quadratic performance. Based on a proposal by
1620 Martin von Löwis at
1621 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1622
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001623- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001624 having been closed (for instance, a read() call could return some
1625 previously buffered data). Patch by Dmitry Vasiliev.
1626
Antoine Pitrou05608432009-01-09 18:53:14 +00001627- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1628 flag to work properly. Furthermore, when specifying -u, the text stdout
1629 and stderr streams have line-by-line buffering enabled (the default being
1630 to buffer arbitrary chunks of data).
1631
Raymond Hettinger35631532009-01-09 03:58:09 +00001632- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1633 instead of ints (reducing its size from 4 to 8 times thereby reducing
1634 Python's overall memory).
1635
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001636- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1637 an existing .py counterpart, override the co_filename attributes of all
1638 code objects if the original filename is obsolete (which can happen if the
1639 file has been renamed, moved, or if it is accessed through different paths).
1640 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1641
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001642- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1643 one byte. Also fixes the meaning of len() so that it returns the number of
1644 items, rather than the size in bytes.
1645
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001646- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1647
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001648- Issue #4747: When the terminal does not use utf-8, executing a script with
1649 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1650
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001651- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001652 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001653
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001654- Issue #3680: Reference cycles created through a dict, set or deque iterator
1655 did not get collected.
1656
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001657- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1658 where the tp_hash and tp_dict slots are both NULL.
1659
Georg Brandlccc47b62008-12-28 11:44:14 +00001660- Issue #4759: None is now allowed as the first argument of
1661 bytearray.translate(). It was always allowed for bytes.translate().
1662
Skip Montanaro80072cb2008-12-23 03:51:14 +00001663- Added test case to ensure attempts to read from a file opened for writing
1664 fail.
1665
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001666- Issue #3106: Speedup some comparisons (str/str and int/int).

1672 print elapsed times, not only when some objects are uncollectable /
1673 unreachable. Original patch by Neil Schemenauer.
1674
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001675- Issue #3439: Add a bit_length method to int.
1676
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001677- Issue #2173: When getting device encoding, check that return value of
1678 nl_langinfo is not the empty string. This was causing silent build
1679 failures on OS X.
1680
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001681- Issue #4597: Fixed several opcodes that weren't always propagating
1682 exceptions.
1683
1684- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001685 context manager returns a value that cannot be converted to a bool.
1686
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001687- Issue #4445: Replace "sizeof(PyBytesObject)" with
1688 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1689 bytes instances. On a typical machine this saves 3 bytes of memory
1690 (on average) per allocation of a bytes instance.
1691
Christian Heimesa872de52008-12-05 08:26:55 +00001692- Issue #4533: File read operation was dreadfully slow due to a slowly
1693 growing read buffer. Fixed by using the same growth rate algorithm as
1694 Python 2.x.
1695
Antoine Pitrou5504e892008-12-06 21:27:53 +00001696- Issue #4509: Various issues surrounding resize of bytearray objects to
1697 which there are buffer exports (e.g. memoryview instances).
1698
Georg Brandlf9734072008-12-07 15:30:06 +00001699- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1700 method on file objects with closefd=False. The file descriptor is still
1701 kept open but the file object behaves like a closed file. The ``FileIO``
1702 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001703
Antoine Pitroubc420402008-12-07 20:14:49 +00001704- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1710
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001711- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1712 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1713 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1714 of using the replace error handler in PyUnicode_DecodeUTF8().
