A subset of the checks done at connection creation time need to be done at
query routing time. This guarantees that the connection is closed if the
server no longer qualifies as a valid candidate.
Added teset case that checks that a change in the replication topology
correctly breaks the connection.
The tests now reset the replication state using queries and switchover instead of
calling fix_replication(). The results are checked so these tests now test
switchover as well.
Also, reduce printing when verbose is on for any test using the get_output()-function
in fail_switch_rejoin_common.cpp.
The expected and received value are now both logged when an error
occurs. The execution is also cut short to prevent excessive message
flooding as most of the time all comparisons fail.
The test can fail if the Galera nodes aren't synced when the connection to
MaxScale is made. Adding a small sleep should allow the Galera cluster to
stabilize after the configuration switch.
The cdc_datatypes test did not use the correct connector and instead it
used a stale version of the MaxScale CDC Connector. The connector should
be treated as an external dependency and thus cloned at configuration
time.
If a service name contains spaced, e.g. "RW Split Router", those
spaces will be replaced with dashes at startup. Consequently, dashes
must be used when issuing commands.
The test environment is now checked to contain all executables needed for
testing before tests are built. They can be overridden by defining the
relevant HAVE_X variables (currently only HAVE_MYSQLTEST and HAVE_PHP are
defined).
Some of the tests waited for excessively long periods of time for changes
to propagate. With a one second monitor interval, a sleep of around five
seconds should be plenty enough for all monitor related changes to be
propagated to all systems.
- 1 master, 3 slaves
- "stop slave" on server 2
- "disable" log-bin on server 3
- set multi-source replication on server 4
- take down master
- no slave should be promoted
Verifying that the requested replication type matches the one that is
currently in use allows the resetting of the nodes to automatically set up
the correct replication type. This means that a test that invokes
`Mariadb_nodes::require_gtid(true)` before initializing the
TestConnections class is given a replication setup that uses GTID
coordinates instead of file and position.
The users are now created on both the slaves as well as the master. This
allows static binlog coordinates to be used on the slaves and the
replication initialization boils down to a set of SQL queries.
