Store and use a cache of the loaded ModInfo data to mod-info-cache.json
in the mods directory during startup. For simplicity this does not
cache mods added to the controller or host after startup, these get
added to the cache on the next startup.
Implement the shorthand notations that Factorio recognises for colours
where individual components may be left out or the colour specified as
an array of values instead of an object.
Add back unqualified tsconfig.json files to each package that references
both the Node.js build and the browser build. This makes tsc --build
compile both builds when the variant to do is not specified.
Distinguish the Node.js build in the same way the browser build is with
the .node suffix to the tsconfig files it uses. This means
tsconfig.node outputs to dist/node and tsconfig.browser outputs to
dist/browser.
Use a separate folder for the TypeScript build for Node.js in the dist
folder. This makes each type of build consistently have its own output
folder instead of being interleaved with the Node.js build.
Use dist/browser as the output of the browser oriented TypeScript build
of packages instead of dist/web/build. This distinguishes it better
from the Web UI bundle which is put together with webpack.
Rename the config files for the browser build of modules to better
communicate that it's purpose is to compile code for a browser
environment rather than the Web UI in particular. This also aligns with
the "browser" option in package.json, the existing browser.ts entrypoint
in lib, and how the browser environment is typically referred to.
Follow the same pattern as all the other subscribable lists by having a
separate .list and .subscribe permissions for saves. This also fixes
the save list not being visible due to a typo in the permission in the
Web UI.
If the value in a subscribed list is updated while the updatedAtMs
timestamp is kept the same then the caching logic of the subscription
system will cause updates to be silently dropped. Log a warning if a
subscriber catches this happening to help tracking down such cases.
If a link is closed while the prepareDisconnect action is in progress
the link will still try to signal the disconnect ready over the socket
when the prepareDisconnect action completes, which throws due to the
socket no longer being present. This error is not caught due to the
catch happening before the finally on the promise and triggers an
unhandled rejection.
Fix by rearranging the finally to come before the catch on the promise
so that errors are always handled, and checking that the link still has
a session before attempting to send the disconnect ready signal.
When messages were forwarded they were sent using the low level
connector .send method which accepts a message and sends it over the
link. This method sends the message as is with no modification which
means that at no point during the forwarding logic was the message
sequence number that originated from Link A renumbered to the correct
sequence number to send out on Link B which it was forwarded on.
This in turn caused the logic which drops acked messages from the send
buffer to break which in turn meant the resume could cause duplication
of message and/or messages to be lost. With enough duplicated messages
the resume of one connection could cause other connections to drop and
also initiate resume.
Fix by renumbering the sequence on forwarded messages. In the future
the sequences sent and received should also be checked to make sure this
kind of problem does not happen again, this is not done here because
partially updating a running cluster with sequence problems to one that
checks and enforces sequences numbers will be problematic.
When host and instance id in Address was reordered in 1e66f11 the
toString method Address was updated to account for this. Fix toString
showing host addresses as being instance addresses and vice versa.
When a plugin broadcasts an event to instances there may be hosts and
instances in the cluster which does not have the plugin loaded. This
would cause an error to be logged for every instance which does not have
the plugin loaded.
Filter out broadcast events sent to hosts and instances such that
instances and hosts that does not have the event do not received them.
When a request is forwarded from a virtual link to a WebSocket link as
is the case when an instance sends a request to the controller the
origin for the request is a virtual link. Handle this case in
_clearPendingRequests instead of throwing an assertion error.
Track the number of requests currently awaiting a response from a
request handler both from interally issued requests and requests
forwarded from other parties.
Add suffixes like Ms and Ns to variables whos time unit is not in
seconds. This is aligning with a new code style of putting units
on variables that are not in SI base units.
The logical order of clusterio's components are in most places
controller, host, instance, control. It is confusing that Address
breaks this convention and I do not remember I wrote it that way.
Reorder and renumber the host and instance members of Address to
be consistent with most other places.
Change the expected exported name of plugin declarations to be "plugin"
at the main entrypoint instead of the default export. This makes the
plugin's code organisation more flexible especially when using CommonJS
JavaScript modules as they can export additional symbols from the
plugin declaration file.
Implement remotely initiated stopping and restarting of the controller
and hosts. Restarting is implemented by exiting with a non-zero exit
code and relying on a process manager to start the procress again. To
prevent accidentally trying to restart on a system that doesn't have a
process manager present the --can-restart command line option needs to
be passed to enable the restart operation.
Record the time a player was first seen joining an instance in
PlayerStats. For existing stats this value is set to the last
joined time when it is first loaded.
Add custom input component support to the Web UI config in order to
provide a user friendly dropdown selector for the Mod Pack that is
configured as default on the controller and overridden instances.
Provide the kernel, machine, CPU Model, hostname, and Node.js version
fields to SystemInfo and display them in the Web UI. These were added
as metrics exposed to prometheus in b46efeb.
There are more pieces of information about a system than just its CPU,
Memory and disk metrics. To avoid having to build a separate collection
and subscription for metrics and system info, rename the existing system
metrics to system info in anticipation of providing additonal static
system information such as CPU model in it.
If the controller is behind a proxy then the socket.remoteAddress will
be that of the proxy instead of the end client that connected. In this
case the X-Forwarded-For header will contain the address of the end
client, but this should only be relied upon if the party connecting is a
trusted proxy, otherwise a malicious user could spoof the IP address
that is logged by providing a forged X-Forwarded-For header.
Implement a trusted proxy list consisting of a configured list of IP
addresses and/or CIDR blocks and use the last address[1] in the
X-Forwarded-For header if the remoteAddress address of the connecting
party is in the trusted proxy list.

Split out host specific data from RegisterHostData that is not related
to the establishment of a connection to the controller into it's own
HostInfoUpdate event. This allows this data to be updated when the
config values they are taken from are changed.
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.
