Session commands did not trigger a reconnection process which caused
sessions to be closed in cases where recovery was possible.
Added a test case that verifies the patch fixes the problem.
The library is now named "maxtest". The related include-files are, for
now, usable without designating the full include path. This may be changed
later, but would require modifying every test.
GCloud machines has more strict access rights settings. Derect calls of
'chmod' are needed to make all configuration files (e.g. 'fwf/rules') be
accessable by Maxscale.
The slave backend would be closed twice if it would both respond with a
different result and be closed due to a hangup before the master
responded.
Added a test case that reproduced the problem.
It was possible that the query thread got stuck and never saw the updated
insert_val. Making the variable atomic as well as sleeping in between
queries should prevent it.
By removing replication from the equation, the client IP check is more
stable. The get_client_ip function is only used by bug448 and could be
moved there.
The test repeatedly creates connections which exhausts all the available
TCP connections. The test doesn't appear to test any specific
functionality with the repeated reconnections which means removing it
shouldn't be a problem.
The pkill executable is provided by the same package that provides ps
which is why it is more likely to be installed. Seems that the test VMs
don't always have killall installed.
Run the MaxScale process with the maxscale user instead of the root user
to prevent any new files from being owned by a different user.
Cherry-picked the commit a06c122a5e050071589f724758d6bbd3d8d3f419 from
