This test has been failing with:
Wait until record is migrated to lmaster node 0
<30|BAD: node 0 is not dmaster
dmaster: 1
rsn: 8
flags: 0x00010000 MIGRATED_WITH_DATA
data(6) = "value1"
*** TEST COMPLETED (RC=1) AT 2021-02-02 06:18:48, CLEANING UP...
This should never happen. If this really fails then the wait should
time out.
The problem is that wait_until() does:
"$@" || _rc=$?
and vacuum_test_key_dmaster() currently calls ctdb_test_fail() on
failure, which causes the shell to exit. Instead, pass a variant to
wait_until() that simply returns the correct status instead of
exiting.
An alternative would be to change the statement in wait_until() to do:
("$@") || _rc=$?
so it captures the exit. However, this is a global change and
requires more thought.
