# Let's see if FLUSH TABLES WITH READ LOCK can be killed when waiting
|
|
# for running commits to finish (in the past it could not)
|
|
# This will not be a meaningful test on non-debug servers so will be
|
|
# skipped.
|
|
# If running mysql-test-run --debug, the --debug added by
|
|
# mysql-test-run to the mysqld command line will override the one of
|
|
# -master.opt. But this test is designed to still pass then (though it
|
|
# won't test anything interesting).
|
|
|
|
# This also won't work with the embedded server test
