Raise "resume" instead of "connect" when a connection is re-established
after a connection drop. This prevents logic meant to resynchronize
state after a full reconnection from being invoked whenever the
connection was temporarily dropped.
The automatic creation of a self-signed certificate while nice presents
several problems. To make connections not reject the self-signed
certificate the validation of TLS certificates are wholesale disabled,
decreasing the security even when properly set up and trusted
certificates are used.
To make the created self-signed certificate pass validation it is
necessary for it to list the host names it's valid for and to copy it to
each machine that intends to connect to the server. These two steps
complicate automating the process in a reliable way and will likely lead
to confused users seeking to disable TLS certificate validation as the
easy way out to problems.
For these reasons, remove the automating creation of a broke self-signed
certificate, fix validation of certificates and document how to set up
TLS properly. This makes HTTPS recommended when accessing over the
internet, but still something which must be explicitly configured.
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.
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.
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.
Make the config and link libraries compatible with packing for web with
webpack. This would fail due to ws not being web compatible and config
using a node function not available in the web shim for util.
Split up codebase into the packages @clsterio/lib, @clusterio/master,
@clusterio/slave, and @clusterio/ctl using lerna to manage them. This
will allow deployment to use only the parts needed reducing install
size, and better separate the code into shared library, master, slave
and control.
