11
12Core and Builtins
13-----------------
14
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000015- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
16 where the right hand operand is a set of constants, by turning the set into
17 a frozenset and pre-building it as a constant. The comparison operation
18 is made against the constant instead of building a new set each time it is
19 executed (a similar optimization already existed which turned a list of
20 constants into a pre-built tuple). Patch and additional tests by Dave
21 Malcolm.
22
Antoine Pitrouf2c54842010-01-13 08:07:53 +000023- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
24 methods of bytes, bytearray and unicode objects by using a common
25 implementation based on stringlib's fast search. Patch by Florent Xicluna.
26
Mark Dickinson45b63652010-01-16 18:10:25 +000027- Issue #7632: Fix various str -> float conversion bugs present in 2.7
28 alpha 2, including: (1) a serious 'wrong output' bug that could
29 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
30 that occurred in debug builds when parsing certain long numeric
31 strings corresponding to subnormal values, and (3) a number of flaws
32 that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000033
Benjamin Petersonaea44282010-01-04 01:10:28 +000034- The __complex__ method is now looked up on the class of instances to make it
35 consistent with other special methods.
36
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000037- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
38 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
39
Benjamin Petersond12362a2009-12-30 19:44:54 +000040- Issue #7604: Deleting an unset slotted attribute did not raise an
41 AttributeError.
42
Mark Dickinson9ab44b52009-12-30 16:22:49 +000043- Issue #7534: Fix handling of IEEE specials (infinities, nans,
44 negative zero) in ** operator. The behaviour now conforms to that
45 described in C99 Annex F.
46
Mark Dickinsoncbb62742009-12-27 15:09:50 +000047- Issue #1811: improve accuracy and cross-platform consistency for
48 true division of integers: the result of a/b is now correctly
49 rounded for ints a and b (at least on IEEE 754 platforms), and in
50 particular does not depend on the internal representation of an int.
51
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000052- Issue #6834: replace the implementation for the 'python' and 'pythonw'
53 executables on OSX.
54
55 These executables now work properly with the arch(1) command:
56 ``arch -ppc python`` will start a universal binary version of python
57 in PPC mode (unlike previous releases).
58
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +000059- Issue #7466: segmentation fault when the garbage collector is called
60 in the middle of populating a tuple. Patch by Florent Xicluna.
61
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +000062- Issue #7419: setlocale() could crash the interpreter on Windows when called
63 with invalid values.
64

74 implement the relevant rich comparison methods.
75
Mark Dickinsond550c9a2009-11-15 09:57:26 +000076- Issue #7298: fixes for range and reversed(range(...)). Iteration
77 over range(a, b, c) incorrectly gave an empty iterator when a, b and
78 c fit in C long but the length of the range did not. Also fix
79 several cases where reversed(range(a, b, c)) gave wrong results, and
80 fix a refleak for reversed(range(a, b, c)) with large arguments.
81
Raymond Hettingerfc438512009-11-01 20:55:33 +000082- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000370- Issue #6816: runpy now provides a run_path function that allows Python code
371 to execute file paths that refer to source or compiled Python files as well
372 as zipfiles, directories and other valid sys.path entries that contain a
373 __main__.py file. This allows applications that run other Python scripts to
374 support the same flexibility as the CPython command line itself.

387 recursive locks as fast as regular non-recursive locks (previously,
388 they were slower by 10x to 15x).
389

405 failures on systems with slightly bogus mtime behaviour.

408 reading from stdin so that existing input does not confuse it and
409 lead to incorrect entry or an IOError. It also properly flushes it
410 afterwards to avoid the terminal echoing the input afterwards on
411 OSes such as Solaris.
412
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000413- Issue #7233: Fix a number of two-argument Decimal methods to make

918
Antoine Pitroue4501852009-05-14 18:55:55 +0000919- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
920 library. This means, for example, that opening an UTF-16 text file in
921 append mode doesn't add a BOM at the end of the file if the file isn't
922 empty.
923
R. David Murray74b89242009-05-13 17:33:03 +0000924- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
925 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
926 corrects a pydoc regression.
927
R. David Murray99352742009-05-07 18:24:38 +0000928- Issue 5955: aifc's close method did not close the file it wrapped,
929 now it does. This also means getfp method now returns the real fp.

972Core and Builtins
973-----------------
974
Mark Dickinson865e01a2009-05-07 16:37:01 +0000975- Issue #5914: Add new C API function PyOS_string_to_double, and
976 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
977
Eric Smith741191f2009-05-06 13:08:15 +0000978- Issue #3382: float.__format__, complex.__format__, and %-formatting
979 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
980 affects nan -> NAN and inf -> INF.
981
Mark Hammond5a607a32009-05-06 08:04:54 +0000982- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
983 in all operations, including splitdrive, split, etc. splitunc() now issues
984 a PendingDeprecation warning.
985
Eric Smith63376222009-05-05 14:04:18 +0000986- Issue #5920: For float.__format__, change the behavior with the
987 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
988 to be like 'g' but with at least one decimal point and with a
989 default precision of 12. Previously, the behavior the same but with
990 a default precision of 6. This more closely matches str(), and
991 reduces surprises when adding alignment flags to the empty
992 presentation type. This also affects the new complex.__format__ in
993 the same way.
994
Martin v. Löwis011e8422009-05-05 04:43:17 +0000995- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
996
R. David Murrayb18500d2009-05-04 22:59:07 +0000997- Issue #5890: in subclasses of 'property' the __doc__ attribute was
998 shadowed by classtype's, even if it was None. property now
999 inserts the __doc__ into the subclass instance __dict__.
1000
Antoine Pitrou244651a2009-05-04 18:56:13 +00001001- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1002 sequences. Patch by Nick Barnes and Victor Stinner.
1003
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001004- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001005
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001006- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1007 received a new method, detach(). detach() disconnects the underlying stream
1008 from the buffer or text IO and returns it.
1009
Mark Dickinson33841c32009-05-01 15:37:04 +00001010- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1011 floats with absolute value over 1e50. Also remove length
1012 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1013 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001014
Eric Smith741191f2009-05-06 13:08:15 +00001015- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001016 format(complex(1, 2./3), '.5') now produces a sensible result.
1017
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001018- Issue #5864: Fix empty format code formatting for floats so that it
1019 never gives more than the requested number of significant digits.
1020
Eric Smith6dc46f52009-04-27 20:39:49 +00001021- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1022 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1023
Eric Smithcc32a112009-04-26 21:35:14 +00001024- Issue #5835: Deprecate PyOS_ascii_formatd.
1025
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001026- Issue #4971: Fix titlecase for characters that are their own
1027 titlecase, but not their own uppercase.
1028
Benjamin Peterson193152c2009-04-25 01:08:45 +00001029- Issue #5283: Setting __class__ in __del__ caused a segfault.
1030
Mark Dickinsonad476da2009-04-23 19:14:16 +00001031- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1032 z involves nans, infs or negative zeros.
1033
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001034- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001035
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001036- Issue #1869 (and many duplicates): make round(x, n) correctly
1037 rounded for a float x, by using the decimal <-> binary conversions
1038 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1039 consistently agrees with format(x, '.2f').
1040
Benjamin Petersonae937c02009-04-18 20:54:08 +00001041- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1042 some builtin types.
1043
Eric Smith0923d1d2009-04-16 20:16:10 +00001044- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1045
Eric Smith35e84722009-04-16 20:21:28 +00001046- Issue #5515: str.format() type 'n' combined with commas and leading
1047 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001048
1049- Implement PEP 378, Format Specifier for Thousands Separator, for
1050 floats.
1051
Mark Dickinson3370cce2009-04-17 22:40:53 +00001052- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001053 1e11, not 1e12. This avoids printing 13 significant digits in
1054 situations where only 12 of them are correct. Example problem
1055 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1056 long time.)
1057
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001058- Issue #1580: On most platforms, use a 'short' float repr: for a
1059 finite float x, repr(x) now outputs a string based on the shortest
1060 sequence of decimal digits that rounds to x. Previous behaviour was
1061 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001062 Another minor difference is that the new repr switches to
1063 exponential notation at 1e16 instead of the previous 1e17; this
1064 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001065
1066 There's a new sys attribute sys.float_repr_style, which takes
1067 the value 'short' to indicate that we're using short float repr,
1068 and 'legacy' if the short float repr isn't available for one
1069 reason or another.
1070
1071 The float repr change involves incorporating David Gay's 'perfect
1072 rounding' code into the Python core (it's in Python/dtoa.c). As a
1073 secondary consequence, all string-to-float and float-to-string
1074 conversions (including all float formatting operations) will be
1075 correctly rounded on these platforms.
1076
1077 See issue 1580 discussions for details of platforms for which
1078 this change does not apply.
1079
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001080- Issue #5759: float() didn't call __float__ on str subclasses.
1081
Georg Brandlabc38772009-04-12 15:51:51 +00001082- The string.maketrans() function is deprecated; there is a new static method
1083 maketrans() on the bytes and bytearray classes. This removes confusion about
1084 the types string.maketrans() is supposed to work with, and mirrors the
1085 methods available on the str class.
1086
R. David Murraydc6da8a2009-04-09 22:16:43 +00001087- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1088 its clarity and its speed.
1089
Matthias Klose091c7b12009-04-07 13:24:27 +00001090- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1091 to avoid compiler warnings.
1092
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001093- Issue #3739: The unicode-internal encoder now reports the number of characters
1094 consumed like any other encoder (instead of the number of bytes).

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001229- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1230
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001231- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1232 byte, and the 'C' code only accepts a unicode character.
1233
Georg Brandl406b3d82009-04-11 21:24:37 +00001234- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1235 when hitting the recursion limit under certain circumstances.
1236
Brett Cannon0759dd62009-04-01 18:13:07 +00001237- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1238
Georg Brandlab6f2f62009-03-31 04:16:10 +00001239- Fix a segfault when running test_exceptions with coverage, caused by
1240 insufficient checks in accessors of Exception.__context__.
1241
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001242- Issue #5604: non-ASCII characters in module name passed to
1243 imp.find_module() were converted to UTF-8 while the path is
1244 converted to the default filesystem encoding, causing nonsense.
1245
Benjamin Peterson09832742009-03-26 17:15:46 +00001246- Issue #5126: str.isprintable() returned False for space characters.
1247
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001248- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1249 the end sys.path, for compatibility with the system install of Python.
1250
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001251- Issue #4688: Add a heuristic so that tuples and dicts containing only
1252 untrackable objects are not tracked by the garbage collector. This can
1253 reduce the size of collections and therefore the garbage collection overhead
1254 on long-running programs, depending on their particular use of datatypes.
1255
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001256- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1259
Mark Dickinsonbd792642009-03-18 20:06:12 +00001260- Issue #4258: Make it possible to use base 2**30 instead of base
1261 2**15 for the internal representation of integers, for performance
1262 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1263 --enable-big-digits option to configure, which overrides the
1264 default. Add sys.int_info structseq to provide information about
1265 the internal format.
1266
Mark Dickinson081dfee2009-03-18 14:47:41 +00001267- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1268 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1269 and sizeof(Py_UNICODE) == 2.
1270
Eric Smith8ec90442009-03-14 12:29:34 +00001271- Issue #5237: Allow auto-numbered fields in str.format(). For
1272 example: '{} {}'.format(1, 2) == '1 2'.
1273
Antoine Pitrou652e7072009-03-13 19:25:20 +00001274- Issue #5392: when a very low recursion limit was set, the interpreter would
1275 abort with a fatal error after the recursion limit was hit twice.
1276
Matthias Klose042f1332009-04-04 14:32:42 +00001277- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
1278 short file names.

R. David Murray548ac412009-04-02 19:44:43 +00001284 mailbox.MH.get_message().
1285
Hye-Shik Chang944820b2009-04-02 10:33:16 +00001286- Issue #5640: Fix _multibytecodec so that CJK codecs don't repeat
1287 error substitutions from non-strict codec error callbacks in
1288 incrementalencoder and StreamWriter.
1289
Georg Brandl33c28812009-04-01 23:07:29 +00001290- Issue #5656: Fix the coverage reporting when running the test suite with

1308
Brett Cannon7f6b4f82009-03-30 21:30:26 +00001309- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1310 bytes already but the failure was non-obvious.
1311
Jesse Noller7af4ef82009-03-30 16:47:15 +00001312- Issue #5177: Multiprocessing's SocketListener class now uses
1313 socket.SO_REUSEADDR on all connections so that the user no longer needs

1319 (typically /dev/zero under Unix) could crash the interpreter.
1320
Benjamin Peterson59406a92009-03-26 17:10:29 +00001321- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1322 io.BufferedRandom have been deprecated for removal in Python 3.2.
1323
Lars Gustäbel42e00912009-03-22 20:34:29 +00001324- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1325 forever on incomplete input. That caused tarfile.open() to hang when used
1326 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1327 partial bzip2 compressed data.
1328
Mark Dickinson79f52032009-03-17 23:12:51 +00001329- Issue #2110: Add support for thousands separator and 'n' type

1345
Mark Dickinsonae681df2009-03-21 10:26:31 +00001346- Issue #5463: In struct module, remove deprecated overflow wrapping
1347 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001348 struct.error instead of returning b'\xff\xff\xff\xff'. The
1349 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1350 have been removed from the struct module.

1369 contained non ascii character on windows.
1370
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001371- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1372 source has already been decoded into str.
1373
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001374- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1375 rotating the object pointer by 4 bits to the right.
1376
Mark Dickinson87ec0852009-02-09 17:15:59 +00001377- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1378 it now forces its argument to double before testing for infinity.
1379
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001380- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1381 returns a non-number type.
1382
Benjamin Peterson87618552009-02-08 15:00:52 +00001383- Issue #5182: Removed memoryview.__str__.

1388 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001389
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001390- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001391 were suppressing all exceptions. These include list() and bytearray().
1392
Mark Dickinson1124e712009-01-28 21:25:58 +00001393- Issue #4707: round(x, n) now returns an integer if x is an integer.
1394 Previously it returned a float.
1395
Antoine Pitroub52ec782009-01-25 16:34:23 +00001396- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1397 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1398 evaluation loop is compiled with a new dispatch mechanism which gives
1399 speedups of up to 20%, depending on the system, on various benchmarks.
1400
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001401- Issue #4874: Most builtin decoders now reject unicode input.

1407
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001408- Issue #4838: When a module is deallocated, free the memory backing the
1409 optional module state data.
1410
Mark Dickinson8055afd2009-01-17 10:04:45 +00001411- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1412 type to (void *).
1413
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001414- Issue #4935: The overflow checking code in the expandtabs() method common
1415 to str, bytes and bytearray could be optimized away by the compiler, letting
1416 the interpreter segfault instead of raising an error.
1417
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001418- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1419 __next__ method.
1420
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001421- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

1428
Antoine Pitrouab868312009-01-10 15:40:25 +00001429- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1430 common cases are optimized thanks to a dedicated fast path and a moderate
1431 amount of loop unrolling.
1432
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001433- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1434 collecting the oldest generation) so that allocating lots of objects without
1435 destroying them does not show quadratic performance. Based on a proposal by
1436 Martin von Löwis at
1437 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1438
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001439- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001440 having been closed (for instance, a read() call could return some
1441 previously buffered data). Patch by Dmitry Vasiliev.
1442
Antoine Pitrou05608432009-01-09 18:53:14 +00001443- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1444 flag to work properly. Furthermore, when specifying -u, the text stdout
1445 and stderr streams have line-by-line buffering enabled (the default being
1446 to buffer arbitrary chunks of data).
1447
Raymond Hettinger35631532009-01-09 03:58:09 +00001448- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1449 instead of ints (reducing its size from 4 to 8 times thereby reducing
1450 Python's overall memory).
1451
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001452- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1453 an existing .py counterpart, override the co_filename attributes of all
1454 code objects if the original filename is obsolete (which can happen if the
1455 file has been renamed, moved, or if it is accessed through different paths).
1456 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1457
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001458- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1459 one byte. Also fixes the meaning of len() so that it returns the number of
1460 items, rather than the size in bytes.
1461
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001462- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1463
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001464- Issue #4747: When the terminal does not use utf-8, executing a script with
1465 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1466
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001467- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001468 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001469
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001470- Issue #3680: Reference cycles created through a dict, set or deque iterator
1471 did not get collected.
1472
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001473- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1474 where the tp_hash and tp_dict slots are both NULL.
1475
Georg Brandlccc47b62008-12-28 11:44:14 +00001476- Issue #4759: None is now allowed as the first argument of
1477 bytearray.translate(). It was always allowed for bytes.translate().
1478
Skip Montanaro80072cb2008-12-23 03:51:14 +00001479- Added test case to ensure attempts to read from a file opened for writing
1480 fail.

1486
Antoine Pitrou621601a2008-12-17 23:18:19 +00001487- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1488 print elapsed times, not only when some objects are uncollectable /
1489 unreachable. Original patch by Neil Schemenauer.
1490
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001491- Issue #3439: Add a bit_length method to int.
1492
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001493- Issue #2173: When getting device encoding, check that return value of
1494 nl_langinfo is not the empty string. This was causing silent build
1495 failures on OS X.
1496
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001497- Issue #4597: Fixed several opcodes that weren't always propagating
1498 exceptions.
1499
1500- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001501 context manager returns a value that cannot be converted to a bool.
1502
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001503- Issue #4445: Replace "sizeof(PyBytesObject)" with
1504 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1505 bytes instances. On a typical machine this saves 3 bytes of memory

Antoine Pitrou08838b62009-01-21 00:55:13 +00001850- Issue #5008: When a file is opened in append mode with the new IO library,
1851 do an explicit seek to the end of file (so that e.g. tell() returns the

2136 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2137 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2138 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002140- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002141 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002142 from test support, which does the conversion.
