The mm test was on the heavy side and the workload can be reduced for the
sake of testing only the functionality.
The mm_mysqlmon test did not check the initial state of the
server. Although not necessary, adding it will help detect test failures
caused by broken replication.
mxs1457_ignore_deleted did not stop the monitors before breaking the
replication and attempting to use MaxScale. As the test expects
authentication to work regardless of the actual state of the servers, the
monitors need to be disabled before a query is attempted.
The ssh_node function now supports printf style arguments. This is used to
simplify command execution on the nodes.
Curreltny, in addition to its old usage, it is used to drop extra
databases when replication is started.
The stack traces weren't logged as the LOG_ALERT priority wasn't enabled
by default. As an alert is intended to be something that must leave a
trace somewhere, and as such, it must not be possible to disable it. For
this reason, it is acceptable to always log the message if the priority is
LOG_ALERT.
Added the -rdynamic linker flag so that all symbols are exported when
linking MaxScale.
As the stack trace is printed in a signal handler, the first attempt
should be to print the stack trace to the standard output. This way the
output is printed before an attempt to use malloc is made when it is
logged to the logfile.
If the client sends data before authentication is complete, it must not be
discarded and it needs to be processed like as if it was sent in a
separate network packet.
If a module command returns a json object, it will always be
returned to the caller, irrespective of whether the command
itself succeeded or not.
Otherwise, if the command failed and if the module command has
set an error message, that error message will be returned as a
json object containing the error message.
Since the module command interface was expanded to include a JSON output
parameter, there is no longer a need for an output DCB. As the JSON can be
printed by both maxadmin and the REST API, this allows the removal of
explicit output formatting in module commands.
The yargs framework combined with the pkg packaging causes the executable
name to be mangled on installation. For this reason, the usage should be
explicitly added to each command.
If the authenticator option is enabled, no users are loaded and no errors
have occurred in the user loading process, the service credentials are
injected.
The `script_timeout` and `journal_max_age` parameters weren't handled in
the monitor alteration code.
Also added missing documentation to maxadmin help output for
`alter monitor`.
When the database firewall filter is used in white-list mode,
'USE <db>' should be allowed. When connecting, it is always
possible to specify the database anyway so restricting
'USE <db>' serves no purpose.
If a script variable resolves to an empty string, the replacement attempt
will fail with an out-of-memory error. The following realloc call will
fail as it requires a positive value for the new size.
The test now checks that both users with passwords and users without
passwords work through MaxScale when skip_authentication is enabled. In
addition to this, the test also makes sure that the wrong password and a
missing password are properly detected.
The result of the authentication should be ignored but the scramble that
is calculated as a side-effect still needs to be stored. This can be done
by altering the SQL used to get the matching row to only match on the
username, not the network address.
Also expanded the test case to cover the use of bad credentials.
The avrorouter now uses the parameters from the source service. This
removes the need for redundant parameter definition in the avrorouter
service when they are defined in the binlogrouter service as parameters.
Added some missing configuration sanity checks and updated the tutorial to
reflect the new configuration method introduced in 2.1.
The documentation stated that the binlogrouter would use the cache
directory to store the binary log files. In reality, there was no default
value and the service would fail to start without a binlogdir parameter.
The router now uses the data directory (/var/lib/maxscale/) to store the
binary logs.
Set the default value of mariadb10-compatibility to true. This is in line
with the fact that most installations should use the router with a MariaDB
10.0 server or newer.
