The combination of the default values of `disable_sescmd_history=false`
and `max_slave_connections=100%` does not make sense as it is not possible
to find a replacement slave in case an active one fails.
This header defines some general functions and maxscale main() return
values. Most of it is still public, but there were some functions
which were moved to a core header.
Some of the JSON errors weren't handled which could cause problems when a
malformed schema definition is read.
Also added more error messages for situations when opening of the files
fails.
Moved some typedefs to router.h and server.h, changed a few
constants to these enums. Renamed some types in config.h to
remove "Gateway".
There are still some functions in the public header which are
only used in core, but they seem to fit the theme of public functions
so were not moved.
handleError can detect READ ONLY transaction set when problem_dcb ==
rses->forced_node->bref_dcb.
Session will be closed and rses->forced_node set to NULL
All modules now declare a name for the module. This is name is added as a
prefix to all messages logged by a module. The prefix should help
determine which part of the system logs a message.
The external config.h header defined functions and structures that are
intended to be used by modules. The internal header contains functions
that are used only by the MaxScale core.
The module commands now support an optional flag for arguments that when
enabled checks that the argument module name matches the registered domain
name. This can be used to enforce argument type validity for arguments
that are given to modules that expect objects of a certain type.
For example, this is used by the cache and dbfwfilter to prevent valid
filters but of the wrong type being given as arguments.
To test the configuration validation and default value generation, the
functions needed to be refactored to allow parameters to be passed
directly to the function.
Some uses of monitorStart didn't pass the monitor parameters to the
function call. This caused runtime configuration of monitors to not have
any parameters as they never got their parameters.
The schemarouter now accepts all router_options values as parameters.
Also fixed a mistake in the documentation where the router options section
was listed twice.
The parameters that readwritesplit uses now use the new system. This
removes the need for the qualified parameter processing found in config.c.
All values for router_options are now also accepted as parameters. The
router_options is deprecated and support for it will be removed in a
future version.
