Some systems may resolve localhost to ::1 while Factorio doesn't respond
to RCON connection over IPv6 loopback, this causes instances startup to
fail. Fix by using 127.0.0.1 instead of localhost.
Write new file contents to a temporary file and then rename over the
target file to avoid data loss in the unlikely event there's an error
writing the new file contents or the process is interrupted.
Resolves#416.
Somehow the step of automatically obtaining the right address to apply
to slave.public_address, and asking for the master url and token for ctl
installations was implemented but the code to actually set it in the
relevant config was forgotten.
If the session to a slave is lost while gathering metrics the error
would propagate out to the metrics route handler and break collection of
statistics. Fix by handling errors thrown from sending the getMetrics
request to slaves.
Don't bother doing the prepareDisconnect dance if the connection is
already broken. This avoids having to wait until the connection times
out when a slave gives up on a current connection and starts a new one.
If a connection has timed out the most likely cause is the connection
going stale, in which case calling close could take up to 30 seconds
before the ws lib gives up on waiting for the close message. Terminate
the connection instead on the Node.js side. Note that Firefox does not
permit applications from closing connections with a code other than
1000, or in the range 3000-4999.
The INI format Factorio use differs from what the ini package parse and
produce. Most notably no escape mechanism exists in Factorio's parser
which causes instance paths containing among other thing the # character
to completely break. Fix by replacing the ini package with a Factorio
compatible implementation of INI parsing and serialization.
Resolves the problem in #414.
Move the save list subscription permission to be after the save list
permission as these two permissions are logically related to each other
and both need to be granted to view the save list in the web interface.
Add the roles and their permissions for the user the control connection
is connected as along with updates when these change. This enables the
web interface to know which permissions it has available to it.
Add optional limit to the number of log records to return in the
log query request to avoid having the web interface instance console
download the entire log for only to show a few hundred lines from it.
To make it possible to query the end of the log instead of just the
start add an order option as well.
With the instance status unknown now meaning assigned slave is offline
the save list buttons can now easily be disabled using this status.
Disable the upload save, download save and delete save buttons when the
slave is offline or the instance is not assigned to a slave.
Since the connector refactor the action of sending a message on a
connector that is in the process of connecting changed from queuing up
the message to send it to throwing an error. To avoid events forwarded
by the slave to to the master when the connection is down from being
logged as an error forwardEventToMaster has to explicitly drop them.
Prevent ordering issues with save notifications on stop by making the
save list update part of the stop action instead of some unspecificed
amount of time later.
This also fixes the issue of the connection being closed before the last
instance sends it save list on slave shutdown.
Provide a convenience method for checking if the Master-Slave link is
fully online via a .connected property. This is true if the link has
been establised, is not in the dropped state, and not in the process of
disconnecting.
The activeConnectors mapping is from session id to connector, but the
master refactor in 67219ed accidentally changed it to try deleting the
entry by the connector reference instead. Possibly mistaking it for a
Set instead of a Map.
Refine the state flow used in the connector abstractions to better
handle close while connecting and resuming. The new logic is to close
the connection immediately in these two states instead of continuing
trying to connect and then giving up some point later.
For the connectors the handshake state is split into connecting
and resuming, new is replaced by closed, and the closing state is turned
into a boolean flag as it's possible that closing is desired while
connecting, connected or resuming. The connecting state is not present
in the server connector because there's nothing for the server to do in
that connector state.
The timeout logic is completely removed, once a connection attempt is
started for the client it will continue to attempt to connect, attempt
to resume dropped connections and attempt reconnects until either an
authentication error occurs or the client explicitly requests to close
the connection.
A new session timeout is added to control how long to attempt to resume
the connection until it's considered dead and invalidated. This allows
stale connections to give up earlier, and swallow up less data while in
the dropped but not yet invalidated state.
For the client side sending messages while it's connecting has been
changed to throw an error instead of queuing up the message and
(possibly) sending it after the connection is established. Code
shouldn't try to send messages without knowing if the connection it's
trying to send them over is active or not.
