Category: PF/tests Group: Pathfinder CVS Head >Status: Open >Resolution: None >Priority: 4 Private: No Submitted By: Stefan Manegold (stmane) Assigned to: Peter Boncz (boncz) Summary: PF: ~500 tests randomly fail on Solaris x86 Initial Comment: While working fine until Saturday Jan 13 2007 with the (old) XQuery_0-14 branch, 200+ pathfinder tests fail randomly (different tests every day) since Tuesday Jan 16 2007 with the old XQuery_0-14 branch on Solaris x86 (32-bit) with: !ERROR: interpret: no matching MIL operator to '����������������R.e��������()'. Due to compilation problems introduced on Saturday Jan 13 2007 and fixed only on Monday Jan 15 2007, there were no pathfinder test results for (a.o.) Solaris x86 on Sun Jan 14 & Mon Jan 15. Hence, any checkins on the old XQuery_0-14 branch between Sat Jan 13 2007 and Mon Jan 15 2007 might have triggered these problems. On the development trunk (HEAD), the tests worked fine until Tuesday Jan 16, but fail as described since Wednesday Jan 17, i.e., after the above mentioned checkins had been propagated from the XQuery_0-14 branch to the development trunk. See e.g., http://monetdb.cwi.nl/testing/projects/monetdb/Current/pathfinder/.mTests103/GNU.32.32.d-SunOS5.10/benchmarks_MBench/qr01.out.00.html http://monetdb.cwi.nl/testing/projects/monetdb/Current/pathfinder/.mTests103/GNU.32.32.d-SunOS5.10/tests_i18n/bad-001.out.00.html (Note that the failing tests might change randomly on a daily basis.) Although Solaris x86 32-bit is not our prime target platform, these problems might occur due to a bug (possibly some memory initialization problem or alike) that exists in the code, but "by chance" is not triggered on the other platforms... If possible, please fix on the development trunk (HEAD) because the old XQuery_0-14 branch is considered obsolete, now. ---------------------------------------------------------------------- >Comment By: Stefan Manegold (stmane) Date: 2007-01-26 00:56 Message: Logged In: YES user_id=572415 Originator: YES For the records: With assertions enabled, the problems still occur. ---------------------------------------------------------------------- Comment By: Peter Boncz (boncz) Date: 2007-01-22 23:54 Message: Logged In: YES user_id=591107 Originator: NO I think a fix in src/monet/yytree.mx that zaps the ret struct on errors should eradicate this problem ---------------------------------------------------------------------- Comment By: Stefan Manegold (stmane) Date: 2007-01-22 13:11 Message: Logged In: YES user_id=572415 Originator: YES The "strange characters" in the error message are actually 0xDB, i.e., our version of DeadBeef to wipe-out memory before being freed in GDKfree() (which is only done with assertions enabled). Hence, "somewhere", "someone" seems to access previously freed memory (and/or not yet re-initialized) memory... ---------------------------------------------------------------------- Comment By: Stefan Manegold (stmane) Date: 2007-01-22 11:47 Message: Logged In: YES user_id=572415 Originator: YES The problem seems to occur only when configured with --enable-strict --enable-assert (default in the development trunk "Current"), but not when configured with --disable-strict --disable-assert (default in the release branch "Stable"). ---------------------------------------------------------------------- Comment By: Stefan Manegold (stmane) Date: 2007-01-20 15:35 Message: Logged In: YES user_id=572415 Originator: YES In fact, about 500 tests are effected. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=1640248&group_id=56967 ------------------------------------------------------------------------- Take Surveys.
