See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
Some of the older tests expected results that didn't make much sense. The
mxs1643_extra_events test should expect the master to devolve into the
Running state when it is set into read-only. This is understandable as a
set of servers consisting only of slaves is rather disorienting.
In mxs1678_relay_master breaking the replication of the relay master
devolves it into the Running state as well as all slaves replicating from
it. This is a better result as in a real-life scenario only the valid and
up-to-date slaves would be used.
This commit introduces changes that fix the relay master detection that
was broken by the merge from 2.1 into 2.2 by commit
1ecd791887994209eb29e56e1271f8c407cd0cdf.
In 2.2, the master server ID is used to detect whether a slave is actually
replicating from a master. The value is still displayed even if the slave
is not actively replicating from a master. The commit in 2.1 causes this
value to be stored unconditionally if it is available. By checking the
value of Last_IO_Errno and comparing it to a list of known error codes, we
know whether the slave is replicating properly.
The slave detection in 2.2 correctly identifies a broken slave with a
stopped IO thread. Due to this, the test case must be modified to check
that the relay master is not a slave if the IO thread is stopped.
The code had a note in that states that the test uses custom code
backported from 2.2 and that it should be updated to use common code once
merged into 2.2.
Added a small sleep to make sure the monitor picks up the changes in the
topology.
