The agent string was inspired by the HTTP User-Agent header to serve as
a way to identify what's connecting to the cluster. While there may
have been vision of other software connecting to a controller than the
Clusterio provided ones this seems highly unlikely to ever happen.
Remove redundant agent string for now.
Memory sizes are usually written using the prefixes with a base of 1024
instead of 1000. Implment formatting of the power of two based prefixes
for displaying memory sizes.
Implement simple collection of basic real time system metrics of hosts
and the controller for the purpose of displaying them in the Web UI. The
metrics are collected by the controller at a configurable interval and
pushed out to web clients currently subscribed to the metrics.
Use a separate ES Module based build for the web version of the lib
package. This fixes the rebuild on watched files changing in lib
failing with a TS1479 error.
Add host.factorio_port_range config to hosts that specify a pool of
ports that gets automatically assigned to instances which do not have a
game_port set on them. This allows setting up a port range that's
forwarded to the host on the router and then configure that port range
on the host and have instances automatically get assigned an available
port when they start up.
Resolves: #448
Due to configs needing a location to be deserialised it's not possible
to cleanly replace RawInstanceInfo with the InstanceInfo class. Rename
it to HostInstanceUpdate to better represent its purpose.
Refactor away the config group concept and simplyfy the way config
fields are defined. Fields are defined directly as properties of the
static field fieldDefinitions on the class itself with a separate
interface to declare the types of fields.
This makes it possible to easily make accessing the config fields type
checked in a way that lets plugins extend the interfaces with their own
config options by adding additional fields to the interface via
declation merging.
Refactor the Config and ConfigGroup classes to match the JSON data class
pattern with toJSON, toRemote and fromJSON methods replacing the load,
init, and serialize methods. Since fromJSON requires extra information
the messages structures passes around the plain JSON representation of
the configs instead of serialising instances of the config classes
automatically.
If a new save is added to the saves list of an instance the current save
selected to be loaded by default changes its state without updating the
mtime of the file on disk, which in turn means basing the updatedAt
property on mtime will not work with caching. Fix by having a separate
updatedAt property that is set by the controller whenever the save
details changes from the controller's perspective.

Process updates of the resource EventSubscriber are subscribed to and
have it keep a mapping of id to value syncronised with event provider as
long as there are subscription callbacks registered with it. The
mapping is kept around after the last callback is unsubscribed so that
it can be efficiently resynced with the resource based on the updatedAt
timestaps of individual elements.
This allows the EventSubscriber to provide the right building blocks to
provide its values to React components via the the useSyncExternalStore
hook. This in turn greatly simplifies the web_ui models for the
subscribed resources.
Reduce complexity in the implementation of EventSubscriber by requiring
a control link be passed to its constructor. This is possible after the
change in 8c724e3 made the web interface control instance available to
plugins at init time.
Since subscriptions are handlede per link there's no need for the
eventReplay to be returned as a part of the SubscriptionRequest, it can
be sent and processed normally as an event. Simplify the logic by
sending eventReplay as an event and remove SubscriptionResponse.
Remove the reliance a reference to the Controller to get the link that a
subscription is tied to by explicitly handling the SubscriptionRequest
and passing the link to the SubscriptionController.
Notify the SubscriptionController that a connection closed from the
Connection instead of having the subscription controller set up an event
to do so. This simplifies the logic on the SubscriptionController's
side.
Entites that didn't have an updatedAt time at the time of creation will
default to having one set to 0. Since entities with an updatedAt time
greater than lastResponseTime is expected to be returned this means that
these entities would not be included when a client does its initial sync
subscribing to a resource. Change the default lastResponseTime
requested so that these entities are included.
Skip calling the subscription function that should provide an event
replay if the client is unsubscribing from the event. This avoids
having to check if the client is subscribing in every subscription
function.
Keep a copy of the instance saves details on the controller so that
saves can be queried even when the host is disconnected and the
controller can properly track and provide updates on the saves to
its clients.
Refactor HostUpdatesEvent, InstanceDetailsUpdatesEvent, ModUpdatesEvent,
ModPackUpdatesEvent and UserUpdatesEvent to have multiple updates of the
entities they support in each event. This is intended to make the events
capable of syncing the entire list that they represent.
Download and cache needed mods to run instance mod packs on instance
startup. To avoid opening too many download streams at once only one
mod is downloaded at a time.
Structure the storage of mods on the controller into into a reusable
component in preparation for the host using the same kind of mod storage
to retrieve and cache the mods it needs to run mod packs on instances.
Add helper to serialise the calls made to an async function such that no
overlapping invocations happen to the async function by queue up calls
made while it's running to continue after it's running.
Replace PluginWebApi's requirePath member with npmPackage which is only
populated if the package is not marked as private and the requirePath
matches the name. This prevents the public /api/plugins endpoint from
leaking filesystem paths into the controller.
Use the JSON data class pattern for User, Role, and PlayerStats and move
them into lib/src/data. This means that User is purely data now and
can't reference role objects directly. To make it possible easily check
permissions attached to roles and store data only visible on the
controller on user objects a ControllerUser type is introduced which is
linked with the UserManager and can therefore reference role objects
directly.
Resolves#525.
Separate out the serialisation of the invocations to saveData with an
AsyncSerialMergingCallback helper than has unit tests covering its
functionality.
When creating temporary files use the pattern `.tmp.ext` instead of
`.ext.tmp` to be consistent with Factorio which creates `.tmp.zip` files
during saving.
If patching fails this will leave a `.tmp.zip` file in the instance saves
directory which is ignored by the default save selector.
Resolves#486.
Add controller.autosave_interval config that specifies the frequency
which controller config, hosts, instances, users, mod packs and plugin
specific data which is held in memory should be automatically flushed to
disk if they have changed since the last time they were saved. This
prevents data loss in the event of a server crash.
Plugins can use the onSaveData hook to save its own data at the same
time as the controller does and this obsoletes making an autosave
interval in the plugin.
Resolves#523.
Clean up the configuration for compiling TypeScript for the Web
interface to us its own tsconfig.web.json config files and reference the
TypeScript source files directly in the configuration and imports
instead of files compiled to dist.
To properly support recompliation with TypeScript's projects feature
each package's tsconfig.web.json file is set to output the build to
dist/web_build which is then ignored in .npmignore. Webpack is still
used to create the proper build in dist/web, so this is mainly to make
TypeScipt's compiler happy but it also allows the root tsconfig.json
file to include the web interface code, meaning running the build script
now also checks the typing of the web interface.
Final part of #491.
Output message_validate.js to both dist/src/data and src/data. This
allows tools to directly consume the TypeScript sources in src/data
without throwing an error due to message_validate being missing.
Resolve circular dependency of controller depending on web_ui and web_ui
depending on controller by moving the type from controller that was used
in web_ui to lib.
Add strong typing of the invokeHook function to prevent incorrect
paramaters being passed to plugin hooks. This detected a few places
where the parameters passed were incorrect.
Move BaseControllerPlugin to controller/src/BaseControllerPlugin.ts
Move BaseInstancePlugin to host/src/BaseInstancePlugin.ts
Move BaseControlPlugin to ctl/src/BaseCtlPlugin.ts
Move BaseWebPlugin to web_ui/src/BaseWebPlugin.ts
This solves the circular package dependency problem of the base plugins
needing types that are available only in the dependencies to lib.
Be consistent with the usage of tabs as indents in all JSON files in the
project. This makes it easier to configure editors to emit the right
indents when manually editing these files.
When defining a generic type where a type argument is never used
as a part of the type itself, TypeScript will consider two instances of
the generic type with different values for the type to be the same.
This caused the handle method to accept any handler for any
Request/Event, ignoring the event/request type completely.
Fix by specifying the constructor to return the intersection of the type
itself and the Request/Event type.
