1) Only two backends are set up for extra-port
2) The setting is checked to work by connecting directly to servers
3) The server connections are saturated before starting MaxScale
4) MaxScale logs are checked for extra-port-related messages
The test case covers a few bugs that were fixed by the previous
commits. The first part of the test covers the case when master
reconnection fails while session command history is being executed. The
second part of the test makes sure exceeding the session command history
will prevent master reconnections from taking place.
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 test appears to fail when the throttling is unable to keep the QPS
high enough for the test to pass. To reduce the likelihood of this, lower
the limit to 500 QPS.
In theory, the minimum delay of one millisecond in the delayed_call limits
the filter to a maximum QPS of 1000 as each query would wait for at least
a millisecond before being routed. This is yet to be proven but it would
explain why the tests are having a hard time approaching that level of
QPS.
Before the MXS-2250 fix, the following ends with an error:
CREATE TEMPORARY TABLE t (f INT);
DESCRIBE t;
Reason is that the first is sent to the master (and the table will
not be replicated to slaves) and the latter to some slave.
The bug appears when a session command that is executed on the master
fails. The logic in the code doesn't take this case into consideration
when it processes failed connections.
Basic tests can be executed with 15 machines Master/slave backend. Tests have label BIG_REPL_BACKEND Default template modified to support big backend. Tests temporaraly labeled as UNSTABLE to prevent their execution nightly
For big test maxscale.cnf is automatically generated for any number of nodes

The masking_user test creates a database over a masked connection.
As 'CREATE DATABASE DB' is not fully parsed the test will fail since
it creates a database.
To allow the test to pass, we turn off the strict requirement that
all statements must be fully parsed.
MXS-2236 Add own long test and possibility to run tests under Valgrind
Long test executes INSERT queries, transactions, prepared statements in parallel to create weird load on Maxscale to catch crashes and leaks
Test is not included into ctest scope. Test should be executed manually. For BuildBot (and also for run_test.sh) 'test_set' should be set 'NAME# ./long_test'
Time to run test is defined by 'long_test_time' variable (in seconds)
Possibility to run Maxscale under Valgrind is also added. To run Maxscale under Vaslgrind 'use_valgrind=yes' variable have to be defined
By repeatedly doing reads instead of one read per second, it is more
likely that MXS-2311 is reproduced. This is still not a deterministic
process but in theory it can reproduce the problem.
Added a test case that does a set of sanity checks on the monitor. As the
monitor is very simple, there are not a lot of things to test without
access to the actual instances (e.g. ExeMgr failures need to be tested).
Currently the test always passes as ColumnStore clusters aren't
implemented for the test framework.
