[Python-Dev] Meaty debugging mystery

2003年6月29日 22:38:44 -0400

Neil Schemenauer was running regrtest with -r and got a segfault. He
whittled it down to running just
 -u bsddb test_logging test_bsddb3
This was confirmed on Win2K, Win98, and some version of Linux. He also
discovered that the problem went away if test_logging.py's
 locale.setlocale(locale.LC_ALL, '')
was commented out.
I've since found that the problem persists if
+ All the suite.addTest() calls in bsddb/test/test_basics.py are
 commented out except for
 suite.addTest(unittest.makeSuite(BTreeMultiDBTestCase))
and
+ All the entries in test_bsddb3.py's test_modules list are commented
 out except for
 'test_basics',
Then running yields this output:
test_bsddb3
test01_GetsAndPuts (bsddb.test.test_basics.BTreeMultiDBTestCase) ... ok
test02_DictionaryMethods (bsddb.test.test_basics.BTreeMultiDBTestCase) ...
ok
test03_SimpleCursorStuff (bsddb.test.test_basics.BTreeMultiDBTestCase) ...
ok
test04_PartialGetAndPut (bsddb.test.test_basics.BTreeMultiDBTestCase) ... ok
test05_GetSize (bsddb.test.test_basics.BTreeMultiDBTestCase) ... ok
test06_Truncate (bsddb.test.test_basics.BTreeMultiDBTestCase) ... ok
test09_MultiDB (bsddb.test.test_basics.BTreeMultiDBTestCase) ... FAIL
and that's when the crash happens.
I don't have time to dig into this more. Looks like a good one, though!
