Instances require a number of modifications leading to it not being
able to be converted into a function. The main one is that there is a
list of config elements that cannot be set via the edit command and
either have to be set via different means or cannot be set. To stop
these fields constantly sending error messages, we disregard adding them
to the file in the first place.
Using an event emmiter, the fields can now be set correctly in the
master config. Null values are now handled correctly, and numbers are also set
correctly.
Also now using the system described by Hornwitser, in using
libConfig.MasterConfig.groups to get definitions. Now all that's needed
is to re-read the updated data back into clustorio.
ctl master config edit [editor]
is the new structure; it can take an optional editor, and will prio this
editor over any other editor, such as one set by env vars. Generally,
the prio goes like this: argv supplied editor > EDITOR env var > VISUAL
env var. Things needing to be done are marked with a TODO.
Implimented framework for edit command, including ability to get a temp
file, open an editor on the file, then resume code execution once the
editor exits.
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.
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.
Add a generate slave token button to the web interface and modify the
generateSlaveToken message and corresponding ctl command to have the
slave id be optional. The random id is the desired behavior when adding
a slave with the installer, as it'll ask for the token for the new slave
and deduce the id from the token.
