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.
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.
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

maxscale-system-test changed in order to control test environment by itself.
Every test checks which machines are running, compare with list of needed machines
and start new VMs is they are missing in the running machines list.
Tests are executiong MDBCI commands, MDBCI executable should be in the PATH
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
Rewrote the bug561.sh test as the error_messages test that covers what was
tested by the script as well as some new parts that were untested. This
revealed a bug in the error messages where MaxScale always returns the
database name in the error.
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.
Grouped all binlogrouter and avrorouter tests so that they are executed as
the last tests. This helps prevent some side effects that result from the
"aggressive" replication modifications the tests do. Also removed some
commented out test cases.
The tests were consistently unstable and as a result of this did not
provide any actionable output. In addition to this these two test were the
longest running tests in the whole MaxScale test suite so a re-design was
warranted.
Instead of emulating a client and a server failure, testing functionality
provides for a test that is faster, more precise and provides more
actionable output. Due to the single-threadedness of the new test, no
cross-thread depencies are present. In addition to this, the superfluous
log flushing was not done as it almost always happened after all
transactions were already complete.
The estimated savings in test time alone is around 1100 seconds (roughly
18 minutes).
