If only the config of an instance is updated the dirty flag of the
instance is not set, which results in changes being discarded when the
controller shuts down afterwards.
Fix by always triggering the update logic when an instance field is
changed.
Add config entries to controller and host for the Factorio username and
token to use when talking to the Factorio APIs. If set an username and
token is not set in factorio.settings then these settings are used,
making it easy to configure one set of credentials for a cluster/host.
For running more public provide your own hardware clusters, there's an
option to disable controller sharing the credential with the hosts so
that each host have to set their own credentials.
When passing methods around they lose their binding to this, which means
the fromJSON methods no longer has this be their class. Fix by binding
the methods to the class they belong to before passing them on to the
datastore.
Remove some assumptions that prevent subscription listeners from working on an
instance. This means allowing the host to forward the event from the instance
to the controller; correctly storing subscription listeners by address rather
than by connection; and a bunch of network and event stuff to correctly clean up
a listener.
Remove the assumption that all subscriptions events contains the updates
property. This meant fixing inconsistent types; always checking if the property
existed; fixing lots of the tests that made incorrect assumptions.
Minior fixes:
- Fix double firing of listener callbacks on first connection.
- Fix synced being set to true too early on first connection.
- Fix edge case interaction between last response and last snapshot for values
with updated set as 0.
Also change the the output made during the start of tests to indicate something
is happening when start up is slow and allow for silent testing to reduce the
amount of text output to the console.
Lack of typing was resulting in admin name being serialized to storage as a number and breaking websocket communications protocol due to type mismatch: expected string, got number.
Fixes#536
Due a bad order of operations when a host connection was closed the
event handler listening on "close" to remove the host from the
hostConnections mapping was added after the HostConnection's event
handler listening on "close" and invoking plugin hooks in response to
the host going offline. This in turn causes plugins that send
broadcasts in repsonse to thos hooks to throw an error due to the
broadcast sending code assuming connections that exist are valid target
to send messages to.
Fix by ordering the listener for the removal of the host connection
before the listener invoking plugin events.
Build and minify the Web UI using swc instead of babel, tsc and terser.
This results in a significant speedup of the build process as it skips
checking types and uses native code to do the minification.
To prevent accidental type errors being introduced the TypeScript
compiler is still used to perform type checking on the Web UI files.
Due to peer dependency resolving shenanigans the swc/core package had to
be added to the workspace, controller and web_ui to avoid pnpm creating
a duplicate install of webpack that break the build.
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.
Always send the instance details update when an instance is reassigned,
not just when it is unassigned. The idea for not sending an update when
assigned to a host was that the host would send an update on the status
that in turn updates the instance details. However this is not actually
the case; when a stopped instance is reassigned its status does not
change so the update is ignored.
Set the save's updatedAtMs timestamp when clearing the save list of a
reassigned or deleted instance. This fixes the Web UI not updating the
saves list to remove the saves when an instance is reassigned.
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 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.
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.
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.
