12Core and Builtins
13-----------------
14
Mark Dickinsond59b4162010-03-13 11:34:40 +000015- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
16 PyMemberDefs could produce an internal error; raise TypeError instead.
17
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000018- Issue #7845: Rich comparison methods on the complex type now return
19 NotImplemented rather than raising a TypeError when comparing with an
20 incompatible type; this allows user-defined classes to implement their own
21 comparisons with complex.
22
Victor Stinner52f6dd72010-03-12 14:45:56 +000023- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
24 (SIGINT). If an error occurs while importing the site module, the error is
25 printed and Python exits. Initialize the GIL before importing the site
26 module.
27
Benjamin Petersonae5f2f42010-03-07 17:10:51 +000028- Issue #7173: Generator finalization could invalidate sys.exc_info().
29
Victor Stinner45b9be52010-03-03 23:28:07 +000030- Issue #7544: Preallocate thread memory before creating the thread to avoid
31 a fatal error in low memory condition.
32
Victor Stinner6aa278e2010-03-03 00:18:49 +000033- Issue #7820: The parser tokenizer restores all bytes in the right if
34 the BOM check fails.
35
Benjamin Peterson23e018a2010-02-27 17:40:01 +000036- Handle errors from looking up __prepare__ correctly.
37
Larry Hastings1373a072010-02-24 22:49:58 +000038- Issue #5939: Add additional runtime checking to ensure a valid capsule
39 in Modules/_ctypes/callproc.c.
40
Eric Smith0facd772010-02-24 15:42:29 +000041- Issue #7309: Fix unchecked attribute access when converting
42 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
43 strings.
44
Eric Smithabb28c62010-02-23 00:22:24 +000045- Issue #6902: Fix problem with built-in types format incorrectly with
46 0 padding.
47
Eric Smith4e260c52010-02-22 18:54:44 +000048- Issue #7988: Fix default alignment to be right aligned for
49 complex.__format__. Now it matches other numeric types.
50
Eric Smith68af50b2010-02-22 14:58:30 +000051- Issue #5988: Remove deprecated functions PyOS_ascii_formatd,
52 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
53 and PyOS_string_to_double instead. See issue #5835 for the original
54 deprecations.
55
Antoine Pitrou05b7c562010-02-02 22:47:00 +000056- Issue #7385: Fix a crash in `MemoryView_FromObject` when
57 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
58
Mark Dickinsonbc099642010-01-29 17:27:24 +000059- Issue #7788: Fix an interpreter crash produced by deleting a list
60 slice with very large step value.
61
Eric Smithf7bb5782010-01-27 00:44:57 +000062- Issue #7766: Change sys.getwindowsversion() return value to a named
63 tuple and add the additional members returned in an OSVERSIONINFOEX
64 structure. The new members are service_pack_major, service_pack_minor,
65 suite_mask, and product_type.
66
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000067- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
68 could crash in many places because of the PyByteArray_AS_STRING() macro
69 returning NULL. The macro now returns a statically allocated empty
70 string instead.
71
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000072- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
73 where the right hand operand is a set of constants, by turning the set into
74 a frozenset and pre-building it as a constant. The comparison operation
75 is made against the constant instead of building a new set each time it is
76 executed (a similar optimization already existed which turned a list of
77 constants into a pre-built tuple). Patch and additional tests by Dave
78 Malcolm.
79
Antoine Pitrouf2c54842010-01-13 08:07:53 +000080- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
81 methods of bytes, bytearray and unicode objects by using a common
82 implementation based on stringlib's fast search. Patch by Florent Xicluna.
83
Mark Dickinson45b63652010-01-16 18:10:25 +000084- Issue #7632: Fix various str -> float conversion bugs present in 2.7
85 alpha 2, including: (1) a serious 'wrong output' bug that could
86 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
87 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +000088 strings corresponding to subnormal values, (3) a memory leak for
89 some values large enough to cause overflow, and (4) a number of
90 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +000091
Benjamin Petersonaea44282010-01-04 01:10:28 +000092- The __complex__ method is now looked up on the class of instances to make it
93 consistent with other special methods.
94

96 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
97
Benjamin Petersond12362a2009-12-30 19:44:54 +000098- Issue #7604: Deleting an unset slotted attribute did not raise an
99 AttributeError.
100
Mark Dickinson9ab44b52009-12-30 16:22:49 +0000101- Issue #7534: Fix handling of IEEE specials (infinities, nans,
102 negative zero) in ** operator. The behaviour now conforms to that
103 described in C99 Annex F.
104
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000105- Issue #1811: improve accuracy and cross-platform consistency for
106 true division of integers: the result of a/b is now correctly
107 rounded for ints a and b (at least on IEEE 754 platforms), and in
108 particular does not depend on the internal representation of an int.
109
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000110- Issue #6834: replace the implementation for the 'python' and 'pythonw'
111 executables on OSX.
112
113 These executables now work properly with the arch(1) command:
114 ``arch -ppc python`` will start a universal binary version of python
115 in PPC mode (unlike previous releases).
116
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000117- Issue #7466: segmentation fault when the garbage collector is called

121 with invalid values.
122
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000123- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
124 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
125
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000126- Issue #7085: Fix crash when importing some extensions in a thread
127 on MacOSX 10.6.

130
Mark Dickinson6f1d0492009-11-15 13:58:49 +0000131- Issue #6970: Remove redundant calls when comparing objects that don't
132 implement the relevant rich comparison methods.
133
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000134- Issue #7298: fixes for range and reversed(range(...)). Iteration
135 over range(a, b, c) incorrectly gave an empty iterator when a, b and
136 c fit in C long but the length of the range did not. Also fix
137 several cases where reversed(range(a, b, c)) gave wrong results, and
138 fix a refleak for reversed(range(a, b, c)) with large arguments.
139
Raymond Hettingerfc438512009-11-01 20:55:33 +0000140- Issue #7244: itertools.izip_longest() no longer ignores exceptions

382 an archive. The new implementation is significantly faster and can
383 be wrapped in a :class:`io.BufferedReader` object for more speedups.
384 It also solves an issue where interleaved calls to `read()` and
385 `readline()` give wrong results. Patch by Nir Aides.

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

552 support the same flexibility as the CPython command line itself.
553
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000554- Issue #7318: multiprocessing now uses a timeout when it fails to establish

R. David Murrayba311052009-12-04 00:09:14 +0000914- Issue #7431: use TESTFN in test_linecache instead of trying to create a
915 file in the Lib/test directory, which might be read-only for the
916 user running the tests.
917
R. David Murray35768ad2009-11-15 00:23:21 +0000918- Issue #7324: add a sanity check to regrtest argument parsing to
919 catch the case of an option with no handler.
920
R. David Murray7dc72cc2009-11-14 16:13:02 +0000921- Issue #7312: Add a -F flag to run the selected tests in a loop until
922 a test fails. Can be combined with -j.
923
Antoine Pitrou060cee22009-11-13 16:29:04 +0000924- Issue #6551: test_zipimport could import and then destroy some modules of
925 the encodings package, which would make other tests fail further down
926 the road because the internally cached encoders and decoders would point
927 to empty global variables.
928
Antoine Pitrou941ee882009-11-11 20:59:38 +0000929- Issue #7295: Do not use a hardcoded file name in test_tarfile.

935 tests instead of tempfile.tempdir. This prevents the tests from sharing state
936 between concurrent executions on the same system.
937
Brett Cannon0ae45112009-11-05 01:17:22 +0000938- Issue #7248: In importlib.test.source.util a try/finally block did not make

940 calling methods on the object.
941
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000942- Issue #7222: Make thread "reaping" more reliable so that reference
943 leak-chasing test runs give sensible results. The previous method of
944 reaping threads could return successfully while some Thread objects were
945 still referenced. This also introduces a new private function:
946 :func:`_thread._count()`.
947
R. David Murray27144602009-10-19 15:26:16 +0000948- Issue #7151: fixed regrtest -j so that output to stderr from a test no
949 longer runs the risk of causing the worker thread to fail.
950
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000951- Issue #7055: test___all__ now greedily detects all modules which have an
952 __all__ attribute, rather than using a hardcoded and incomplete list.
953
R. David Murray0bc11ae2009-10-18 22:18:17 +0000954- Issue #7058: Added save/restore for things like sys.argv and cwd to

956 and a new section in the summary report at the end.

959
Brett Cannon3c273842009-07-20 00:14:29 +0000960- Fixed tests in importlib.test.source.test_abc_loader that were masking

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001230*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001231
1232Core and Builtins
1233-----------------
1234
Mark Dickinson865e01a2009-05-07 16:37:01 +00001235- Issue #5914: Add new C API function PyOS_string_to_double, and
1236 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1237
Eric Smith741191f2009-05-06 13:08:15 +00001238- Issue #3382: float.__format__, complex.__format__, and %-formatting
1239 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1240 affects nan -> NAN and inf -> INF.
1241
Mark Hammond5a607a32009-05-06 08:04:54 +00001242- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1243 in all operations, including splitdrive, split, etc. splitunc() now issues
1244 a PendingDeprecation warning.
1245
Eric Smith63376222009-05-05 14:04:18 +00001246- Issue #5920: For float.__format__, change the behavior with the
1247 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1248 to be like 'g' but with at least one decimal point and with a
1249 default precision of 12. Previously, the behavior the same but with
1250 a default precision of 6. This more closely matches str(), and
1251 reduces surprises when adding alignment flags to the empty
1252 presentation type. This also affects the new complex.__format__ in
1253 the same way.
1254
Martin v. Löwis011e8422009-05-05 04:43:17 +00001255- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1256
R. David Murrayb18500d2009-05-04 22:59:07 +00001257- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1258 shadowed by classtype's, even if it was None. property now
1259 inserts the __doc__ into the subclass instance __dict__.
1260
Antoine Pitrou244651a2009-05-04 18:56:13 +00001261- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1262 sequences. Patch by Nick Barnes and Victor Stinner.
1263
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001264- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001265
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001266- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1267 received a new method, detach(). detach() disconnects the underlying stream
1268 from the buffer or text IO and returns it.
1269
Mark Dickinson33841c32009-05-01 15:37:04 +00001270- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1271 floats with absolute value over 1e50. Also remove length
1272 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1273 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001274
Eric Smith741191f2009-05-06 13:08:15 +00001275- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001276 format(complex(1, 2./3), '.5') now produces a sensible result.
1277
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001278- Issue #5864: Fix empty format code formatting for floats so that it
1279 never gives more than the requested number of significant digits.
1280
Eric Smith6dc46f52009-04-27 20:39:49 +00001281- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1282 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1283
Eric Smithcc32a112009-04-26 21:35:14 +00001284- Issue #5835: Deprecate PyOS_ascii_formatd.
1285
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001286- Issue #4971: Fix titlecase for characters that are their own
1287 titlecase, but not their own uppercase.
1288
Benjamin Peterson193152c2009-04-25 01:08:45 +00001289- Issue #5283: Setting __class__ in __del__ caused a segfault.
1290
Mark Dickinsonad476da2009-04-23 19:14:16 +00001291- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1292 z involves nans, infs or negative zeros.
1293
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001294- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001295
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001296- Issue #1869 (and many duplicates): make round(x, n) correctly
1297 rounded for a float x, by using the decimal <-> binary conversions
1298 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1299 consistently agrees with format(x, '.2f').
1300
Benjamin Petersonae937c02009-04-18 20:54:08 +00001301- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1302 some builtin types.
1303
Eric Smith0923d1d2009-04-16 20:16:10 +00001304- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1305
Eric Smith35e84722009-04-16 20:21:28 +00001306- Issue #5515: str.format() type 'n' combined with commas and leading
1307 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001308
1309- Implement PEP 378, Format Specifier for Thousands Separator, for
1310 floats.
1311
Mark Dickinson3370cce2009-04-17 22:40:53 +00001312- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001313 1e11, not 1e12. This avoids printing 13 significant digits in
1314 situations where only 12 of them are correct. Example problem
1315 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1316 long time.)
1317
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001318- Issue #1580: On most platforms, use a 'short' float repr: for a
1319 finite float x, repr(x) now outputs a string based on the shortest
1320 sequence of decimal digits that rounds to x. Previous behaviour was
1321 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001322 Another minor difference is that the new repr switches to
1323 exponential notation at 1e16 instead of the previous 1e17; this
1324 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001325
1326 There's a new sys attribute sys.float_repr_style, which takes
1327 the value 'short' to indicate that we're using short float repr,
1328 and 'legacy' if the short float repr isn't available for one
1329 reason or another.
1330
1331 The float repr change involves incorporating David Gay's 'perfect
1332 rounding' code into the Python core (it's in Python/dtoa.c). As a
1333 secondary consequence, all string-to-float and float-to-string
1334 conversions (including all float formatting operations) will be
1335 correctly rounded on these platforms.
1336
1337 See issue 1580 discussions for details of platforms for which
1338 this change does not apply.
1339
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001340- Issue #5759: float() didn't call __float__ on str subclasses.
1341
Georg Brandlabc38772009-04-12 15:51:51 +00001342- The string.maketrans() function is deprecated; there is a new static method
1343 maketrans() on the bytes and bytearray classes. This removes confusion about
1344 the types string.maketrans() is supposed to work with, and mirrors the
1345 methods available on the str class.
1346
R. David Murraydc6da8a2009-04-09 22:16:43 +00001347- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1348 its clarity and its speed.
1349
Matthias Klose091c7b12009-04-07 13:24:27 +00001350- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1351 to avoid compiler warnings.
1352
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001353- Issue #3739: The unicode-internal encoder now reports the number of characters
1354 consumed like any other encoder (instead of the number of bytes).

Mark Dickinsonbd792642009-03-18 20:06:12 +00001520- Issue #4258: Make it possible to use base 2**30 instead of base
1521 2**15 for the internal representation of integers, for performance
1522 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1523 --enable-big-digits option to configure, which overrides the
1524 default. Add sys.int_info structseq to provide information about
1525 the internal format.

1635 rotating the object pointer by 4 bits to the right.
1636
Mark Dickinson87ec0852009-02-09 17:15:59 +00001637- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1638 it now forces its argument to double before testing for infinity.
1639
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001640- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1648 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001649
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001650- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001651 were suppressing all exceptions. These include list() and bytearray().
1652
Mark Dickinson1124e712009-01-28 21:25:58 +00001653- Issue #4707: round(x, n) now returns an integer if x is an integer.
1654 Previously it returned a float.
1655
Antoine Pitroub52ec782009-01-25 16:34:23 +00001656- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1657 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1658 evaluation loop is compiled with a new dispatch mechanism which gives
1659 speedups of up to 20%, depending on the system, on various benchmarks.
1660
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001661- Issue #4874: Most builtin decoders now reject unicode input.

1667
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001668- Issue #4838: When a module is deallocated, free the memory backing the
1669 optional module state data.
1670
Mark Dickinson8055afd2009-01-17 10:04:45 +00001671- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1672 type to (void *).
1673
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001674- Issue #4935: The overflow checking code in the expandtabs() method common
1675 to str, bytes and bytearray could be optimized away by the compiler, letting
1676 the interpreter segfault instead of raising an error.
1677
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001678- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1679 __next__ method.
1680
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001681- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1682 function no longer attempt to call the __long__ slot to convert an object
1683 to an integer. Only the __int__ and __trunc__ slots are examined.
1684
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001685- Issue #4893: Use NT threading on CE.
1686

1688
Antoine Pitrouab868312009-01-10 15:40:25 +00001689- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1690 common cases are optimized thanks to a dedicated fast path and a moderate
1691 amount of loop unrolling.
1692
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001693- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1694 collecting the oldest generation) so that allocating lots of objects without
1695 destroying them does not show quadratic performance. Based on a proposal by
1696 Martin von Löwis at
1697 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1698
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001699- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001700 having been closed (for instance, a read() call could return some
1701 previously buffered data). Patch by Dmitry Vasiliev.
1702
Antoine Pitrou05608432009-01-09 18:53:14 +00001703- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1704 flag to work properly. Furthermore, when specifying -u, the text stdout
1705 and stderr streams have line-by-line buffering enabled (the default being
1706 to buffer arbitrary chunks of data).
1707
Raymond Hettinger35631532009-01-09 03:58:09 +00001708- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1709 instead of ints (reducing its size from 4 to 8 times thereby reducing
1710 Python's overall memory).
1711
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001712- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1713 an existing .py counterpart, override the co_filename attributes of all
1714 code objects if the original filename is obsolete (which can happen if the
1715 file has been renamed, moved, or if it is accessed through different paths).
1716 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1717
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001718- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1719 one byte. Also fixes the meaning of len() so that it returns the number of
1720 items, rather than the size in bytes.
1721
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001722- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1723
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001724- Issue #4747: When the terminal does not use utf-8, executing a script with
1725 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1726
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001727- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001728 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001729
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001730- Issue #3680: Reference cycles created through a dict, set or deque iterator
1731 did not get collected.
1732
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001733- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1734 where the tp_hash and tp_dict slots are both NULL.
1735
Georg Brandlccc47b62008-12-28 11:44:14 +00001736- Issue #4759: None is now allowed as the first argument of
1737 bytearray.translate(). It was always allowed for bytes.translate().
1738
Skip Montanaro80072cb2008-12-23 03:51:14 +00001739- Added test case to ensure attempts to read from a file opened for writing
1740 fail.

1752
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001753- Issue #2173: When getting device encoding, check that return value of
1754 nl_langinfo is not the empty string. This was causing silent build
1755 failures on OS X.
1756
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001757- Issue #4597: Fixed several opcodes that weren't always propagating
1758 exceptions.
1759
1760- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001761 context manager returns a value that cannot be converted to a bool.
1762
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001763- Issue #4445: Replace "sizeof(PyBytesObject)" with
1764 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1765 bytes instances. On a typical machine this saves 3 bytes of memory
1766 (on average) per allocation of a bytes instance.
1767
Christian Heimesa872de52008-12-05 08:26:55 +00001768- Issue #4533: File read operation was dreadfully slow due to a slowly
1769 growing read buffer. Fixed by using the same growth rate algorithm as
1770 Python 2.x.
1771
Antoine Pitrou5504e892008-12-06 21:27:53 +00001772- Issue #4509: Various issues surrounding resize of bytearray objects to
1773 which there are buffer exports (e.g. memoryview instances).
1774
Georg Brandlf9734072008-12-07 15:30:06 +00001775- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1776 method on file objects with closefd=False. The file descriptor is still
1777 kept open but the file object behaves like a closed file. The ``FileIO``
1778 object also got a new readonly attribute ``closefd``.

1788 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1789 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1790 of using the replace error handler in PyUnicode_DecodeUTF8().

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002395- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2396 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2397 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2398 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002400- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002401 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002402 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00002404- Issue #5083: New 'gui' resource for regrtest.
