Add users, roles and permissions and rework the authentication to use
separate user and slave tokens for control and slave connections
respectively.
Add commands for listing permissions, roles and users, and creating,
editing and deleting roles and users.
Implement notification to plugins for disconnect request, connect, drop,
and close. This allows plugins to properly handle slaves and the master
server shutting down without sending messages that will get lost.
Send a mapping of the plugins the master server has loaded to slaves
vice versa. Limit the plugins that may be loaded by instances to only
those that the master server has loaded.
Allow the factorio_directory specified in the slave config to contain
multiple Factorio installs and add factior.version instance option to
select which install to use for the given instance.
Replace socket.io with plain WebSocket using the ws library as it
doesn't really provide any useful tools over plain WebSocket when it
comes to implementing reliable communication that works across
reconnects. The widespread browser support for WebSocket also means
it has little value to add for the web interface over WebSocket.
Validate messages sent over links with the json schema provided from
them. This aids debugging as an exception will be thrown from the code
sending the bad content.
Replace current configuration mess with a trimmed down version of the
original vision of #200. Configs are collection of config groups that
have fields that can be set. These groups allow organizing the fields
as well as opertunity for plugins to add their own groups. By default
plugins have an auto generated group with the enabled field.
Add startup event to the Clusterio module API which is raised at startup
of a Factorio server. This is to server as a replacement for the
on_init and on_configuration_changed events which cannot be used in
modules.
Adds clusterio_patch_number global from the patcher in order to
implement this. This is a number that's incremented every time the save
is patched.
Change module loading to use a module.json file describing the module
and patch in all files in a directory path passed to the patcher instead
of having to pass the files names and their content. This allows the
specification of which files should be passed to the event_handler lib
and an easy implementation of loading stand alone modules.
Add an implementation of a Prometheus client. This is because the
prom-client implementation seems to have missunderstood how Prometheus
is supposed to work and doesn't allow updating collectors via
asynchronous callback.
Change Instance class to be a subclass of Link and refactor the
communication to and establisment of instances to use a virtual
connection between the slave and the instance. This is simplifies the
implementation of plugin communication for instances.
Replace InstanceRequest with a forwardTo option to Request which does
the task of forwarding in a much cleaner way.
Replace the sources/targets concept with a links array in the message
definitions. Fixes the problem of the actual links the messages applies
to being ambigious when there's multiple sources and targets.
