The test doesn't work when ASAN is used as it increases the memory use of
the process. With the addition of more caches in 2.3, the test is also
more likely to fail. Due to the test being quite useless with ASAN, it is
better to remove it.
If the password field in mysql.user is empty, it is possible that the
actual password is stored in the authentication_string field. Most of the
time this happens due to MDEV-16774 which causes the password to be stored
in the authentication_string field.
Also added a test case that verifies the problem and that it is fixed by
this commit.
The intention was to send the lowest backend version string automatically
to the client instead of the default handshake version. This did not work
as the service version string was used instead of the server version.
It should be possible to START SLAVE and STOP SLAVE irrespective
of which Galera node updates are mode to.
That will be the case if @@log_slave_updates is on and each node
in the Galera cluster have the same server id. Otherwise it will
fail with the current incarnation of BLR.
If
* BLR replicates from a node in a Galera cluster and
* writes are made to all nodes in that cluster,
then
* if a slave to BLR is stopped when it has received an event
originating in a node different than the one BLR is replicating
from
the subsequent (re)starting of the slave will fail because BLR looks
for the last event from a file whose path contains the server id of
the node where the event originates, although it should look for it
in the file whose path contains the server id of the node from which
BLR replicates.
The test adds events to the backends, causing them to go out of sync. It then
uses the reset-replication command to fix the situation and checks replication
is working.
The test adds a scheduled server event, the does failover, rejoin and
switchover and checks that event is manipulated correctly. Also includes
a change to the monitor to fix an invalid ALTER EVENT query when the event
definer has wildcard host.
The behavior of mariadbmon was changed so that it better understands
slaves attempting to replicate. Rewrote the test to accommodate the change
in behavior and take the opportunity to use newer code.
Because of monitor changes, the test had wrong assumptions.
Renamed the test and updated it to use MaxCtrl for some queries.
Also, changed the type of the cycle container in the monitor to an
ordered map so that results are predictable.
