Removed unnecessary sleeps from tests that appear to serve no
purpose. Moveed the kerberos code from the general startup routines to the
kerberos test.
Every time MaxScale was restarted, the test waited for a total of 25
seconds. As MaxScale should start before the command returns, the sleep is
not necessary.
Added StartLimitBurst=0 to the systemd service file to allow rapid
restarts of MaxScale.
The monitor performs simple monitoring of a group replication cluster. It
expects no extra parameters in addition to the common monitor parameters
and will only set master and slave status bits on the servers. It is a
part of the experimental package as it is a very experimental module.
Further improvements would be to add the usage of the synced state.
The static library cannot be linked to the Jansson static library by
CMake. This appears to be a limitation in CMake and a manual combination
of the two files would be required.
For the time being, the connector is only built as a shared library.
The configuration for mxs1323_retry_read now uses shorter timeouts for
monitors. This should help the monitors detect the server failures before
the result of the SELECT returns. also increased the time the query sleeps
before returning.
The CHILDREN parameter expands to a list of server IPs and ports that are
direct descendants of the server that initiated the event.
Also added a note that the variables can expand to empty strings if
nothing matches the criteria of the variable.
The scripts now replace the PARENT variable with the IP and port of the
server that is the direct parent node of the server that initiated the
event. For master-slave clusters, this will be the master IP if the server
that triggered the event is a slave.
If the executed subprocess prefixes its output with either `error:`,
`warning:` or `info:`, the message will be logged on the appropriate
level. If no prefix is provided, the message is logged on the notice
level.
When the subprocess outputs a line, the message should be logged
immediately. This allows automated timestamps for the output of the
executed subprocess.
Since the thread initialization was removed from the process
initialization function, the thread finish function should not be called
in the process finish function.
If both socket and network options are listed, a clear error message is
printed. The usage is also split into two lines to make it clear that the
options should be used separately.
The removal of a server from a service is intended to affect only new
sessions.
Added a test that checks that the connections are kept open even if the
server is removed from the service.
By moving the initialization into Worker::run, all threads, including the
main thread, are properly initialized. This was not noticed before as
qc_sqlite initialized the main thread in the process initialization
callback.
MXS-1412: while discarding a result set don't buffer any data: this
avoids to store useless data.
Additionally the colum definitions buffer is used instead of the offset
value.
The enums exposed by the connector are not intended to be used by the
users of the library. The fact that the protocol, and other, modules used
it was in violation of how the library is intended to be used.
Adding an internal mapping into MaxScale also removes some of the
dependencies that the core has on the connector.
Cleaned up the MaxScale version of the mysql.h header by removing all
unused includes. This revealed a large amount of dependencies on these
removed includes in other files which needed to be fixed.
Also sorted all includes in changed files by type and alphabetical
order. Removed explicit revision history from modified files.
Updated the Connector-C to 3.0.2.
Removed the `mysql_com.h` header from `maxscale/protocol/mysql.h` as it is
already included by `mysql.h` and including it causes errors with
Connector-C 3.0.2.
Organized includes in `maxscale/protocol/mysql.h`.
