The shutdown signal handlers were installed before the workers were
initialized and weren't removed before the workers were deleted. This
would lead to a debug assertion and an eventual crash when a SIGTERM
signal was received outside of the expected scope.
The proper way to do this is to install the handlers only after the system
is up and running and to disable them as soon as the shutdown process
starts.
This mostly happened with the mxs621_unreadable_cnf test as it seemed to
receive a SIGTERM during the execution of the at-exit handlers.
For whatever reason, galera complains on startup about
wsrep_cluster_address missing even when mysql_install_db is run. By making
sure that we configure it before we initialize the database, the problems
seem to go away.
Problem was that 'handler' is a keyword. To make it work,
the keyword must be listed as one of those that turns into
an id where it cannot be used as a keyword.
When a fake handshake response is generated for a connection that hasn't
received the server's handshake, the client's SHA1 would be used with a
static scramble. This, in theory, would weaken the authentication to some
extend so to completely prevent this, a null password is used. This
removes any possibility of the password being exposed.
A few global parameters weren't included in the list of parameters. A few
non-parameter values that were in the parameter object were moved out into
the attributes object. Sorted the parameter alphabetically.
This is needed by tests that use add_test_executable_ex and require
backend SSL. Also fixed a problem in disable_ssl where an empty query was
executed instead of the query itself.
The --quiet option does not make sense in the interactive mode so it isn't
forwarded.
Added code that reports TLS certificate loading errors. The errors
themselves aren't very exact but at least they give a hint as to why it
failed.
The path to the coniguration file must be an absolute path
(CMAKE_SOURCE_DIR) instead of a relative one
(CMAKE_CURRENT_SOURCE_DIR). This fixes cdc_datatypes.
Renamed the postrm script to prerm since it is executed before
uninstallation.
Silenced the output of the systemctl disable commands and added a
conditional restart of MaxScale if a MaxScale instance is running.
Use getent instead of grep to detect if the maxscale user needs to be
created.
The parameter is now optional and uses the correct file. If defined, it
defines the CA certificate that would be used to verify client
certificate. Client certificate verification doesn't seem to currently
work as that requires a custom verification callback that interfaces with
GnuTLS.
