Fix callback typo in Collector constructor jsdocs, add notice that
the collector is passed as the first argument, and use this first
arugument in the built-in collector implementations.
Add a variants array which can specify overriden properties of the
info.json for building multiple versions of the mod at the same time and
fix the additonal_files to allow specifying under what path the file is
put.
Together these two changes allow setting up the build to do all
supported versions at the same time and add specialized code for each
version of Factorio supported.
Add log query and log follow commands which allows inspection of the
combined cluster log. Past entries can be queried via the new queryLog
request. The log is stored into a single flat file for now, though the
performance of this may good enough.
Add winston based logger for master, slave, ctl, lib, and web_ui code.
Logging done from slaves and instances are sent to the master server and
tagged with the instance and/or slave it originated from. This allows
for example error messages to propagate back to the source that iniated
the action. The master server also stores the log to allow it to be
queried at a later point. For slaves a copy of the slave's log is also
stored locally.
Add a sendRcon method to BaseInstancePlugin and the slave's Instance
class. This servers two purposes, one is to reduce the repetition when
send RCON commands particularly from plugins, and the other is to
instrument the RCON commands sent with metrics about duration and size.
Move common functionality between labeled collectors out of
ValueCollector and into a new LabeledCollector class, and use this as
the basis for implementing a Histogram collector.
Under the current system there's no distinction made on the slave side
between instance config files that are present in the filesystem and
instances actually assigned to the slave. Which could lead to problems
with determing if an instance is actually assigned to the slave.
Resolve this issue by separating discovered instances with assigned
instances. Upon startup discovered instances are put into the
discoveredInstanceInfos mapping on the Slave object and all of these are
sent to the master server. The master server in turn sends assignment
requests for all the instances which are assigned to the slave. These
are put into the instanceInfos mapping of the Slave object which can
then be relied up to include only assigned instances.
Add option to set the the maximum amount of commands transmitted in
parallel to the game. Increasing this value allows a greater rate of
commands to be executed.
When the slave metrics request takes more than 10 seconds the response
to the /metrics endpoint ends up being discarded by Prometheus which
defaults to a timeout of 10 seconds. Fix by ignoring slaves that take
longer than 8 seconds to respond to the metrics request.
Amend the error message shown when a message handler is missing from a
plugin with the expected name of the handler and the name of the plugin
it's missing from.
Use 45 seconds as the default heartbeat interval instead of 60. Using
60 causes connections to drop when proxied through Nginx as the default
timeout there is also 60 seconds.
Print only the error message in the console when a connection error is
encountered on the link connector. This reduces log spam on reconnect
for slaves.
Detect and colour the Script and Verbose levels. The format of the
source file for the Script level is slightly different and needs an
update to the output parsing.
Move the definition and implementation of the config command to
lib/shared_comhmands.js, this removes the need for lib config to depend
on the fs module, which is not accessible in web build.
Move the code for loading plugins infos from Node.js packages into a
separate module in order to break it out from lib/plugin.js which is
also used on the web interface side. This resolves a warning of using
an expression with require on the webpack build.
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.
Fix the plugin add command not storing the resolved path for relative
paths passed to it into plugin-list.json and incorrectly resolving any
path containing ./ or ../ instead of only paths starting with these.
Check if the additional file to add exists before trying to pack it.
Note that there may be other ways reading the files could break, but
this should suffice for most cases of getting it wrong.
Move the export and clusterio mod code to the slave package and fix the
path used for them. Refactor tests to use temp/tests/ as the cwd when
running integration tests in order to ensure paths to lua code are
correctly handled.
Add a separate plugin-list.json file for storing which plugins are
available and the path to pass to require in order to load it. This
allows plugins to be published and installed as npm packages. And also
replaces the old method of installing plugins by putting them in the
plugins folder.
Move the code generating the master authentication secret from the
inital value function of the master.auth_secret config entry to the
master startup. Having the authentication secret generated in the
config library poses issues with using the config library in browser.
Send the status of the instance in the repsonse to the listInstances
request and use this status in the integration tests to check if the
instance was started/stopped.
Add the statuses unknown and unassigned for when the status has not yet
been set by a slave and replace the initialized status with starting,
creating_save and exporting_data.
