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.
All possible Promise rejections and exception bubbling should be handled
by either the code creating the exception or the code invoking the
operation that could fail. Treat therefore uncaught exceptions and
unhandled promise rejetions as fatal errors that log a traceback and
immedately terminate the Node.js process.
There are some corner cases with streams that cause them to not emit
finish close or end events which in turn means that code liseting for
these events directly may end up hanging forever. Use stream.finished
to detect end of streams which will handle these cases correctly.
The interface provided by Winston is unusably slow for querying large
logs. Reimplement the log querying with both forwards and backwards
line reading and a simple file based index to skip files which do not
contain any lines matching the filter.
Move the default location of the log files into a configurable logs
folder and split the written logs up by UTC date to more easily allow
deleting of old logs to be performed. The log rotation is implemented
by winston-daily-rotate-file.
The old log format will automatically be migrated to the new format and
location if the target folder for the new logs don't yet exists.
Use relative imports in lib to avoid an issue with webpack thinking
absolute imports inside @clusterio/lib are for a separate module and
giving out warnings for it being missing in package.json.
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.
