If test cases from the test suite fail, you should do the following:
Do not file a bug report before you have found out as much as possible about what when wrong. See the instructions at http://dev.mysql.com/doc/mysql/en/bug-reports.
Check whether an individual test in the test suite also fails when run on its own:
If this fails, and you are compiling MySQL yourself, you
should configure MySQL with
run mysql-test-run.pl with the
--debug option. If this also fails, open a
bug report and upload the trace file
mysql-test/var/tmp/master.trace to the
report, so that we can examine it. For instructions, see
How to Report Bugs or Problems. Please remember to also include
a full description of your system, the version of the
mysqld binary and how you compiled it.
Run mysql-test-run.pl with the
--force option to see whether any other tests
If you have compiled MySQL yourself, check the MySQL Reference Manual to see whether there are any platform-specific issues for your system. There might be configuration workarounds to deal with the problems that you observe. Also, consider using one of the binaries we have compiled for you at http://dev.mysql.com/downloads/. All our standard binaries should pass the test suite!
If you get an error such as
mismatch it means that the output of the test was
not an exact match for the expected output. This could be a
bug in MySQL or it could be that your version of
mysqld produces slightly different results
under some circumstances.
This output from mysql-test-run.pl should
include a diff of the expected and actual result. If unable to
produce a diff, it will instead print out both in full. In
addition, the actual result is put in a file in the
r directory with a
If a test fails completely, you should check the logs file in
mysql-test/var/log directory for
hints of what went wrong.
If you have compiled MySQL with debugging, you can try to
debug test failures by running
mysql-test-run.pl with either or both of
If you have not compiled MySQL for debugging you should
probably do so by specifying the
option when you invoke configure.
