Do not file a bug report before you have found out as much
as possible about what when wrong. See the instructions at
Section 1.8, “How to Report Bugs or Problems”.
Make sure to include the output of
mysql-test-run, as well as contents of
.reject files in the
Check whether an individual test in the test suite also
fails when run on its own:
mysql-test-run --local test-name
If this fails, you should configure MySQL with
--with-debug and run
mysql-test-run with the
--debug option. If this also fails, send
the trace file
ftp://ftp.mysql.com/pub/mysql/upload/ so that we can examine
it. Please remember to also include a full description of
your system, the version of the mysqld
binary and how you compiled it.
Try also to run mysql-test-run with the
--force option to see whether any other
If you have compiled MySQL yourself, check our manual to
see whether there are any platform-specific issues for
your system (see
Section 2.12, “Operating System-Specific Notes”). 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.
The results file has a
extension. A failed test result is put in a file with the
same base name as the result file and a
.reject extension. If your test case
is failing, you should use diff to
.reject files. If you cannot see how
they are different, examine both with od
-c and also check their lengths.
If a test fails completely, you should check the logs file
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 with either or both of
options. See Section E.1.2, “Creating Trace Files”.
If you have not compiled MySQL for debugging you should
probably do so by specifying the
--with-debug option when you invoke
Section 2.8.2, “Typical configure Options”.
