A slight increase of the timeout to 300 seconds should solve some test
failures. The test is extremely hard on the machines and even when run
locally, the test slows down to a crawl.
By truncating the files, tests can be run while the log is being
tailed. If they are removed, the files need to be reopened each time a
test is started.
The test now flushes the INPUT chain of iptables at the start of the
test. This should open all ports even if the OS by default defines some
rules that block ports.
Port 9003 is not open by default in the test environment. Changing it to
port 4006, which is open, will work around this restriction.
Also added the mysql_error output to the error message when the querying
fails.
Dropping a database with DROP DATABASE ... IF NOT EXISTS will cause
warnings to be logged if it doesn't exist. The masking_user test was
missing the part that disables these warnings.
Some of the scripts assumed that other scripts would be located in the
same directory where the current script was executed.
Also fixed the SSL connection creation which depended on an obsolete
environment variable causing all out-of-source SSL tests to fail.
The test can now be run outside of the test source directory. Since the
`test_dir` global variable contains the absolute path to the test source,
all copying of configurations and execution of scripts can be done with
minimal changes.
The re-authentication done in MaxScale caused multiple error packets to be
sent for the same COM_CHANGE_USER. In addition to this, the failure of
authentication did not terminate the client connection.
The change in behavior requires the test case to be changed as well.
Session commands that span multiple packets are now allowed and will
work. However, if one is executed the session command history is disabled
as no interface for appending to session commands exists.
The backend protocol modules now also correctly track the current
command. This was a pre-requisite for large session commands as they
needed to be gathered into a single buffer and to do this the current
command had to be accurate.
Updated tests to expect success instead of failure for large prepared
statements.
