The test now uses standard library threads and lambda functions to make
the code simpler. Also made the test more robust by ignoring any errors
that are caused by the exhaustion of available client side TCP ports.
The expected response counter was not decremented if a transaction replay
was started. This caused the connections to hang which in turn caused the
failure of the mxs1507_trx_stress test case.
If the slave's response differs from the master and the slave sent an
error packet, log the contents of the error. This should make it obvious
as to what caused the failure.
The assertion in routeQuery that expects there to be at least one ongoing
query would be triggered if a query was received after a master had failed
but before the session would close. To make sure the internal logic stays
consistent, the error handler should only decrement the expected response
count if the session can continue.
MySQLAuth now logs the server where the users were loaded from. As only
the initial loading of users causes a log message, it is still possible
for the source server to change without any indication of it.
By enabling the debug messages only at startup, we'll get log messages for
any daemon startup failures and we exlude the verbose parsing errors that
malformed requests cause.
The hard limit of 10 seconds is too strict when taking into account the
fact that infinite refreshes was possible before the bug was fixed. This
also makes testing a lot easier where rapid reloads are necessary.
The first node without a priority would be chosen as the candidate master
and the rest would be ignored. The code must check if neither of the two
nodes have priorities and if so must choose the better one.
Certain MariaDB connectors will use the direct execution for batching
COM_STMT_PREPARE and COM_STMT_EXECUTE execution without waiting for the
COM_STMT_PREPARE to complete. In these cases the COM_STMT_EXECUTE (and
other COM_STMT commands as well) will use the special ID 0xffffffff. When
this is detected, it should be substituted with the ID of the latest
statement that was prepared.
