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
Antoine Pitrouda2ecaf2010-01-02 21:40:36 +000095- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
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
118 in the middle of populating a tuple. Patch by Florent Xicluna.

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.
128
Philip Jenvey1309adb2009-11-17 03:43:14 +0000129- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
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
141 raised during the formation of an output tuple.
142
Benjamin Petersonb2e796a2009-10-28 21:59:39 +0000143- Issue #3297: On wide unicode builds, do not split unicode characters into
144 surrogates.

149
Antoine Pitroub6ef9632009-10-24 20:47:05 +0000150- Support for AtheOS has been completely removed from the code base. It was
151 disabled since Python 3.0.
152
153- Support for several legacy threading libraries has been disabled. These
154 libraries are: Mach C threads, SunOS LWP, GNU pth, Irix threads. Support code
155 will be entirely removed in 3.3.

172
Antoine Pitrou403ce782009-10-14 17:14:16 +0000173- Issue #7065: Fix a crash in bytes.maketrans and bytearray.maketrans when
Antoine Pitrou671141d2009-10-19 19:37:25 +0000174 using byte values greater than 127. Patch by Derk Drukker.
Antoine Pitrou403ce782009-10-14 17:14:16 +0000175
Amaury Forgeot d'Arc7d520792009-10-06 21:03:20 +0000176- Issue #1571184: The Unicode database contains properties for more characters.
177 The tables for code points representing numeric values, white spaces or line
178 breaks are now generated from the official Unicode Character Database files,
179 and include information from the Unihan.txt file.
180
Mark Dickinson2683ab02009-09-29 19:21:35 +0000181- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
182 of producing internally inconsistent Python longs.

213
Benjamin Petersonf1664ae2009-07-01 01:28:55 +0000214- The deprecated PyCObject has been removed.
215
Mark Dickinson835a6c82009-06-30 15:45:17 +0000216- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
217 This fixes a build failure on HP-UX: int32_t and uint32_t are

233 instances from being copied with copy.copy(), and bytes subclasses
234 from being pickled properly.
235
Collin Winter4222e9c2010-03-18 22:46:40 +0000236- Code objects now support weak references.

Mark Dickinsonde604012010-01-01 19:27:32 +0000247- Issue #5080: The argument parsing functions PyArg_ParseTuple,
248 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
249 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
250 DeprecationWarning for float arguments passed with the 'L' format
251 code. This will become a TypeError in a future version of Python,
252 to match the behaviour of the other integer format codes.
253
Georg Brandl1e28a272009-12-28 08:41:01 +0000254- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.
255
Mark Dickinsonf08173b2009-12-03 10:59:46 +0000256- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
257 in PyArg_ParseTupleAndKeywords.

263 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
264 should used for accessing the d_type and d_name members of structures
265 using PyDescr_COMMON.
266
267- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000268
Benjamin Peterson466a7822009-07-02 21:44:01 +0000269- The code flags for old __future__ features are now available again.
270
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000271- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
272 PyCode_Addr2Line().

289
Benjamin Peterson00888932010-03-18 22:37:38 +0000290- Issue #8168: py_compile now handles files with utf-8 BOMS.
291
Benjamin Peterson689a5582010-03-18 22:29:52 +0000292- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
293 detected.
294
Martin v. Löwis4b003072010-03-16 13:19:21 +0000295- Issue #6716/2: Backslash-replace error output in compilall.

306 by an extension module (_posixsubprocess) so that the fork()+exec() can be
307 done safely without the possibility of deadlock in multithreaded applications.
308
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000309- subprocess.Popen now has restore_signals and start_new_session features.
310 The default of restore_signals=True is a new behavior compared to earlier
311 Python versions. This means that signals such as SIGPIPE are not ignored
312 by default in subprocesses launched by Python (Issue #1652).
313

408 It also solves an issue where interleaved calls to `read()` and
409 `readline()` give wrong results. Patch by Nir Aides.

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000572- Issue #6816: runpy now provides a run_path function that allows Python code
573 to execute file paths that refer to source or compiled Python files as well
574 as zipfiles, directories and other valid sys.path entries that contain a

576 support the same flexibility as the CPython command line itself.
577
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000578- Issue #7318: multiprocessing now uses a timeout when it fails to establish

613 a modification is done through it. This fixes inconsistencies and test
614 failures on systems with slightly bogus mtime behaviour.
615
Gregory P. Smith50467882009-11-01 18:42:17 +0000616- Issue #7246 & Issue #7208: getpass now properly flushes input before
617 reading from stdin so that existing input does not confuse it and

Florent Xiclunaf089fd62010-03-19 14:25:03 +0000913- Issue #7783: test.test_support.open_urlresource invalidates the outdated
914 files from the local cache.
915
Florent Xiclunab14930c2010-03-13 15:26:44 +0000916- Issue #7849: Now the utility ``check_warnings`` verifies if the warnings are
917 effectively raised.
918
Florent Xiclunac9c79782010-03-08 12:24:53 +0000919- The four path modules (genericpath, macpath, ntpath, posixpath) share a
920 common TestCase for some tests: test_genericpath.CommonTest.
921
Florent Xicluna0e62a142010-03-06 17:34:48 +0000922- Print platform information when running the whole test suite, or using

Florent Xicluna683a7e72010-03-03 00:06:37 +0000925- Issue #767675: enable test_pep277 on POSIX platforms with Unicode-friendly
926 filesystem encoding.
927
R. David Murray378c0cf2010-02-24 01:46:21 +0000928- Issue #6292: for the moment at least, the test suite runs cleanly if python
929 is run with the -OO flag. Tests requiring docstrings are skipped.
930
Ezio Melotti184bdfb2010-02-18 09:37:05 +0000931- Issue #7712: test.support gained a new `temp_cwd` context manager which is
932 now also used by regrtest to run all the tests in a temporary directory.
933 The original CWD is saved in `support.SAVEDCWD`.
934 Thanks to Florent Xicluna who helped with the patch.
935
Mark Dickinsonedff7af2010-02-13 18:34:53 +0000936- Issue #7924: Fix an intermittent 'XXX undetected error' failure in
937 test_capi (only seen so far on platforms where the curses module
938 wasn't built), due to an uncleared exception.
939
R. David Murraye9e95932010-02-06 05:00:15 +0000940- issue #7728: test_timeout was changed to use test_support.bind_port
941 instead of a hard coded port.
942
R. David Murray445448c2009-12-20 17:28:31 +0000943- Issue #7376: instead of running a self-test (which was failing) when called
944 with no arguments, doctest.py now gives a usage message.
945
R. David Murrayef1992b2009-12-16 15:19:27 +0000946- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
947
R. David Murray596da442009-12-14 23:06:11 +0000948- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
R. David Murray83396232009-12-14 22:45:15 +0000949 instead of a hardcoded port number in test_rapid_restart.
950
R. David Murrayba311052009-12-04 00:09:14 +0000951- Issue #7431: use TESTFN in test_linecache instead of trying to create a
952 file in the Lib/test directory, which might be read-only for the
953 user running the tests.
954
R. David Murray35768ad2009-11-15 00:23:21 +0000955- Issue #7324: add a sanity check to regrtest argument parsing to
956 catch the case of an option with no handler.
957
R. David Murray7dc72cc2009-11-14 16:13:02 +0000958- Issue #7312: Add a -F flag to run the selected tests in a loop until
959 a test fails. Can be combined with -j.
960
Antoine Pitrou060cee22009-11-13 16:29:04 +0000961- Issue #6551: test_zipimport could import and then destroy some modules of
962 the encodings package, which would make other tests fail further down
963 the road because the internally cached encoders and decoders would point
964 to empty global variables.
965
Antoine Pitrou941ee882009-11-11 20:59:38 +0000966- Issue #7295: Do not use a hardcoded file name in test_tarfile.

Antoine Pitrou557934f2009-11-06 22:41:14 +0000968- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
969 primitives such as Lock, RLock, Condition, Event and Semaphore.
970
Brett Cannoncfed0292009-11-05 01:26:57 +0000971- Issue #7248 (part 2): Use a unique temporary directory for importlib source
972 tests instead of tempfile.tempdir. This prevents the tests from sharing state
973 between concurrent executions on the same system.
974
Brett Cannon0ae45112009-11-05 01:17:22 +0000975- Issue #7248: In importlib.test.source.util a try/finally block did not make
976 sure that some referenced objects actually were created in the block before
977 calling methods on the object.
978
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000979- Issue #7222: Make thread "reaping" more reliable so that reference
980 leak-chasing test runs give sensible results. The previous method of
981 reaping threads could return successfully while some Thread objects were
982 still referenced. This also introduces a new private function:
983 :func:`_thread._count()`.
984
R. David Murray27144602009-10-19 15:26:16 +0000985- Issue #7151: fixed regrtest -j so that output to stderr from a test no
986 longer runs the risk of causing the worker thread to fail.
987
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000988- Issue #7055: test___all__ now greedily detects all modules which have an
989 __all__ attribute, rather than using a hardcoded and incomplete list.
990
R. David Murray0bc11ae2009-10-18 22:18:17 +0000991- Issue #7058: Added save/restore for things like sys.argv and cwd to
992 runtest_inner in regrtest, with warnings if the called test modifies them,
993 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +0000994
Mark Dickinson2e304402009-10-04 18:43:54 +0000995- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
996
Brett Cannon3c273842009-07-20 00:14:29 +0000997- Fixed tests in importlib.test.source.test_abc_loader that were masking
998 the proper exceptions that should be raised for missing or improper code
999 object bytecode.
1000
Brett Cannonb49c70c2009-07-15 04:08:33 +00001001- Removed importlib's custom test discovery code and switched to
1002 unittest.TestLoader.discover().

1215
Antoine Pitroue4501852009-05-14 18:55:55 +00001216- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1217 library. This means, for example, that opening an UTF-16 text file in
1218 append mode doesn't add a BOM at the end of the file if the file isn't
1219 empty.
1220
R. David Murray74b89242009-05-13 17:33:03 +00001221- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1222 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1223 corrects a pydoc regression.
1224
R. David Murray99352742009-05-07 18:24:38 +00001225- Issue 5955: aifc's close method did not close the file it wrapped,
1226 now it does. This also means getfp method now returns the real fp.

1269Core and Builtins
1270-----------------
1271
Mark Dickinson865e01a2009-05-07 16:37:01 +00001272- Issue #5914: Add new C API function PyOS_string_to_double, and
1273 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1274
Eric Smith741191f2009-05-06 13:08:15 +00001275- Issue #3382: float.__format__, complex.__format__, and %-formatting
1276 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1277 affects nan -> NAN and inf -> INF.
1278
Mark Hammond5a607a32009-05-06 08:04:54 +00001279- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1280 in all operations, including splitdrive, split, etc. splitunc() now issues
1281 a PendingDeprecation warning.
1282
Eric Smith63376222009-05-05 14:04:18 +00001283- Issue #5920: For float.__format__, change the behavior with the
1284 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1285 to be like 'g' but with at least one decimal point and with a
1286 default precision of 12. Previously, the behavior the same but with
1287 a default precision of 6. This more closely matches str(), and
1288 reduces surprises when adding alignment flags to the empty
1289 presentation type. This also affects the new complex.__format__ in
1290 the same way.
1291
Martin v. Löwis011e8422009-05-05 04:43:17 +00001292- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1293
R. David Murrayb18500d2009-05-04 22:59:07 +00001294- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1295 shadowed by classtype's, even if it was None. property now
1296 inserts the __doc__ into the subclass instance __dict__.
1297
Antoine Pitrou244651a2009-05-04 18:56:13 +00001298- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1299 sequences. Patch by Nick Barnes and Victor Stinner.
1300
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001301- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001302
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001303- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1304 received a new method, detach(). detach() disconnects the underlying stream
1305 from the buffer or text IO and returns it.
1306
Mark Dickinson33841c32009-05-01 15:37:04 +00001307- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1308 floats with absolute value over 1e50. Also remove length
1309 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1310 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001311
Eric Smith741191f2009-05-06 13:08:15 +00001312- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001313 format(complex(1, 2./3), '.5') now produces a sensible result.
1314
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001315- Issue #5864: Fix empty format code formatting for floats so that it
1316 never gives more than the requested number of significant digits.
1317
Eric Smith6dc46f52009-04-27 20:39:49 +00001318- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1319 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1320
Eric Smithcc32a112009-04-26 21:35:14 +00001321- Issue #5835: Deprecate PyOS_ascii_formatd.
1322
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001323- Issue #4971: Fix titlecase for characters that are their own
1324 titlecase, but not their own uppercase.
1325
Benjamin Peterson193152c2009-04-25 01:08:45 +00001326- Issue #5283: Setting __class__ in __del__ caused a segfault.
1327
Mark Dickinsonad476da2009-04-23 19:14:16 +00001328- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1329 z involves nans, infs or negative zeros.
1330
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001331- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001332
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001333- Issue #1869 (and many duplicates): make round(x, n) correctly
1334 rounded for a float x, by using the decimal <-> binary conversions
1335 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1336 consistently agrees with format(x, '.2f').
1337
Benjamin Petersonae937c02009-04-18 20:54:08 +00001338- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1339 some builtin types.
1340
Eric Smith0923d1d2009-04-16 20:16:10 +00001341- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1342
Eric Smith35e84722009-04-16 20:21:28 +00001343- Issue #5515: str.format() type 'n' combined with commas and leading
1344 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001345
1346- Implement PEP 378, Format Specifier for Thousands Separator, for
1347 floats.
1348
Mark Dickinson3370cce2009-04-17 22:40:53 +00001349- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001350 1e11, not 1e12. This avoids printing 13 significant digits in
1351 situations where only 12 of them are correct. Example problem
1352 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1353 long time.)
1354
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001355- Issue #1580: On most platforms, use a 'short' float repr: for a
1356 finite float x, repr(x) now outputs a string based on the shortest
1357 sequence of decimal digits that rounds to x. Previous behaviour was
1358 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001359 Another minor difference is that the new repr switches to
1360 exponential notation at 1e16 instead of the previous 1e17; this
1361 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001362
1363 There's a new sys attribute sys.float_repr_style, which takes
1364 the value 'short' to indicate that we're using short float repr,
1365 and 'legacy' if the short float repr isn't available for one
1366 reason or another.
1367
1368 The float repr change involves incorporating David Gay's 'perfect
1369 rounding' code into the Python core (it's in Python/dtoa.c). As a
1370 secondary consequence, all string-to-float and float-to-string
1371 conversions (including all float formatting operations) will be
1372 correctly rounded on these platforms.
1373
1374 See issue 1580 discussions for details of platforms for which
1375 this change does not apply.
1376
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001377- Issue #5759: float() didn't call __float__ on str subclasses.
1378
Georg Brandlabc38772009-04-12 15:51:51 +00001379- The string.maketrans() function is deprecated; there is a new static method
1380 maketrans() on the bytes and bytearray classes. This removes confusion about
1381 the types string.maketrans() is supposed to work with, and mirrors the
1382 methods available on the str class.
1383
R. David Murraydc6da8a2009-04-09 22:16:43 +00001384- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1385 its clarity and its speed.
1386
Matthias Klose091c7b12009-04-07 13:24:27 +00001387- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1388 to avoid compiler warnings.
1389
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001390- Issue #3739: The unicode-internal encoder now reports the number of characters
1391 consumed like any other encoder (instead of the number of bytes).

1527
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001528- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1529 byte, and the 'C' code only accepts a unicode character.
1530
Georg Brandl406b3d82009-04-11 21:24:37 +00001531- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
1532 when hitting the recursion limit under certain circumstances.
1533
Brett Cannon0759dd62009-04-01 18:13:07 +00001534- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
1535
Georg Brandlab6f2f62009-03-31 04:16:10 +00001536- Fix a segfault when running test_exceptions with coverage, caused by
1537 insufficient checks in accessors of Exception.__context__.
1538
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001539- Issue #5604: non-ASCII characters in module name passed to
1540 imp.find_module() were converted to UTF-8 while the path is
1541 converted to the default filesystem encoding, causing nonsense.

Benjamin Peterson09832742009-03-26 17:15:46 +00001543- Issue #5126: str.isprintable() returned False for space characters.
1544
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001545- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1546 the end sys.path, for compatibility with the system install of Python.
1547
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001548- Issue #4688: Add a heuristic so that tuples and dicts containing only
1549 untrackable objects are not tracked by the garbage collector. This can
1550 reduce the size of collections and therefore the garbage collection overhead
1551 on long-running programs, depending on their particular use of datatypes.
1552
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001553- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1558 2**15 for the internal representation of integers, for performance
1559 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1560 --enable-big-digits option to configure, which overrides the
1561 default. Add sys.int_info structseq to provide information about
1562 the internal format.

1565 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1566 and sizeof(Py_UNICODE) == 2.
1567
Eric Smith8ec90442009-03-14 12:29:34 +00001568- Issue #5237: Allow auto-numbered fields in str.format(). For

1570
Antoine Pitrou652e7072009-03-13 19:25:20 +00001571- Issue #5392: when a very low recursion limit was set, the interpreter would
1572 abort with a fatal error after the recursion limit was hit twice.
1573
Matthias Klose042f1332009-04-04 14:32:42 +00001574- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1584 error substitutions from non-strict codec error callbacks in
1585 incrementalencoder and StreamWriter.
1586
Georg Brandl33c28812009-04-01 23:07:29 +00001587- Issue #5656: Fix the coverage reporting when running the test suite with

1605
Brett Cannon7f6b4f82009-03-30 21:30:26 +00001606- Issue #5236: Change time.strptime() to only take strings. Didn't work with
1607 bytes already but the failure was non-obvious.
1608
Jesse Noller7af4ef82009-03-30 16:47:15 +00001609- Issue #5177: Multiprocessing's SocketListener class now uses

1617
Benjamin Peterson59406a92009-03-26 17:10:29 +00001618- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and
1619 io.BufferedRandom have been deprecated for removal in Python 3.2.
1620
Lars Gustäbel42e00912009-03-22 20:34:29 +00001621- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1622 forever on incomplete input. That caused tarfile.open() to hang when used
1623 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1624 partial bzip2 compressed data.
1625
Mark Dickinson79f52032009-03-17 23:12:51 +00001626- Issue #2110: Add support for thousands separator and 'n' type

1644 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001645 struct.error instead of returning b'\xff\xff\xff\xff'. The
1646 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1647 have been removed from the struct module.

1672 rotating the object pointer by 4 bits to the right.
1673
Mark Dickinson87ec0852009-02-09 17:15:59 +00001674- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1675 it now forces its argument to double before testing for infinity.
1676
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001677- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1678 returns a non-number type.
1679

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001686
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001687- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001688 were suppressing all exceptions. These include list() and bytearray().

1694 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1695 evaluation loop is compiled with a new dispatch mechanism which gives
1696 speedups of up to 20%, depending on the system, on various benchmarks.

1709 type to (void *).
1710
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001711- Issue #4935: The overflow checking code in the expandtabs() method common
1712 to str, bytes and bytearray could be optimized away by the compiler, letting
1713 the interpreter segfault instead of raising an error.
1714
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001715- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1727 common cases are optimized thanks to a dedicated fast path and a moderate
1728 amount of loop unrolling.
1729
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001730- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1731 collecting the oldest generation) so that allocating lots of objects without

1734 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1735

1738 previously buffered data). Patch by Dmitry Vasiliev.
1739
Antoine Pitrou05608432009-01-09 18:53:14 +00001740- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1741 flag to work properly. Furthermore, when specifying -u, the text stdout
1742 and stderr streams have line-by-line buffering enabled (the default being
1743 to buffer arbitrary chunks of data).
1744
Raymond Hettinger35631532009-01-09 03:58:09 +00001745- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1746 instead of ints (reducing its size from 4 to 8 times thereby reducing
1747 Python's overall memory).
1748
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001749- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1750 an existing .py counterpart, override the co_filename attributes of all
1751 code objects if the original filename is obsolete (which can happen if the
1752 file has been renamed, moved, or if it is accessed through different paths).
1753 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1754
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001755- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1756 one byte. Also fixes the meaning of len() so that it returns the number of
1757 items, rather than the size in bytes.
1758
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001759- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1760
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001761- Issue #4747: When the terminal does not use utf-8, executing a script with

1769
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001770- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1771 where the tp_hash and tp_dict slots are both NULL.
1772
Georg Brandlccc47b62008-12-28 11:44:14 +00001773- Issue #4759: None is now allowed as the first argument of

1825 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1826 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1827 of using the replace error handler in PyUnicode_DecodeUTF8().

2148 do an explicit seek to the end of file (so that e.g. tell() returns the

2433 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2434 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2435 skip the tests if DISPLAY is defined but can't be used.

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002438 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002439 from test support, which does the conversion.
