The role of a slave as a host for Factorio servers is not well reflected
in its name and has caused confusion among users. Rename slave to host
to better reflect its role as a host of Factorio servers.
The role of the master server as the party controlling every part of the
cluster is not well reflected in its name and has caused confusion among
users on several occasions. Rename master to controller to better
reflects its role.
In order to import a path inside packages/lib/ in the webpack shared
module environment it has to be declared as shared in both the web_ui
webpack config and the plugin's webpack config. This is rather error
prone and easy to miss. Move the burden of specifying which entrypoints
are valid in lib to lib itself by changing all imports in the web
interface code to import from @clusterio/lib instead sub paths.
For web code this means imports is done like this from now on:
import { libConfig, libLink } from "@clusterio/lib";
For info.js which has to be loadable by both Node.js and web code the
imports are done as follows:
const { libConfig, libLink } = require("@clusterio/lib");
While the Node.js only code can either continue to import sub paths
directly or use the info.js style.
Add a per field access parameter to the config class which specifies
which of master, slave and control can access the given field. A
location is added to the config class to specify which party owns it and
fields which do not have an access parameter are not present in the
config and will throw if attempted to be read from or writen to.
The serialize, load, update, get, set and setProp are ammended with a
location parameter which specifiy where the data is from or destined to
and the access checks are performed to ensure remote access to the
config is still limited by the access parameter of field.
With this system in place the master config can be shared with control
and slave connections without compromising secrets that should stay
private. This is primarily the master authentication secret, but other
plugins may define secrets it does not want to have shared with slave
and/or control connections.
When reducing the collection interval in Prometheus it may be necessary
to to reduce the metrics gathering timeout to ensure it's less than the
interval. Add config options to adjust the timeouts used for metrics
gathering so that these can be set accordingly.
Use lib* prefix for the modules impored from the lib package to help
distinguish them more from ordinary variables. Fix up the naming
convention for files to be consistently lowercase_underscore for
JavaScript files.
Split up codebase into the packages @clsterio/lib, @clusterio/master,
@clusterio/slave, and @clusterio/ctl using lerna to manage them. This
will allow deployment to use only the parts needed reducing install
size, and better separate the code into shared library, master, slave
and control.
