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.
After a session command fails on all connected slaves but succeeds on the
master, the servers that failed are discarded from the pool of valid
servers. If there are available servers, they will be taken into use when
the next read query is performed.
When a query is routed to an unconnected slave, it is taken into use and
the session command history is replayed. If the execution of the history
failed and there were more session commands to be executed, any queued
queries would get lost. This is due to a missing check that would detect
the fact that the server has been discarded.
The test now sets a two minute timeout for all larger operations. This
prevents excessive waiting when the test is executed.
Removed the row count output to stdout to prevent excessive logging when
the terminal contents are written to a file.
Also renamed the file to match the test case name. This should remove the
need to find the source file to test name mapping from the CMakeLists.txt.
The two operations return different types of results and need to be
treated differently in order for them to be handled correctly in 2.2.
This fixes the unexpected internal state errors that happened in all 2.2
versions due to a wrong assumption made by readwritesplit. This fix is not
necessary for newer versions as the LOAD DATA LOCAL INFILE processing is
done with a simpler, and more robust, method.
The test may fail if the client/maxscale/mariadb combo is too slow.
TODO, maybe: today I saw mysql_query() hang (in a poll) when maxscale
disconnected. Is there something that can be done about that?
I added a source directory, base, for stuff that should become part of a common
utility library in the future.
