Add users, roles and permissions and rework the authentication to use
separate user and slave tokens for control and slave connections
respectively.
Add commands for listing permissions, roles and users, and creating,
editing and deleting roles and users.
Upload the created export data zip file to a new /api/upload-export
endpoint on the master server which unpacks it into the appropriate
directory on the master.
If a slave that is already connected attempts connecting the existing
connection for that slave is disconnected. The most common scenario for
this is that the existing connection is stale and the slave is
attempting to connect agan. However if the connection is stale then the
disconnection will take 15 minutes to time out and the slave will appear
unresponsive during this time. Fix this problem by setting the timeout
to 15 seconds before disconnecting the existing connection.
Implement notification to plugins for disconnect request, connect, drop,
and close. This allows plugins to properly handle slaves and the master
server shutting down without sending messages that will get lost.
Fix missing module declarations, broken lings, broken formating and
incorrect scopes in the documentation. For modules split over several
files it appears the only viable option is to use the memberof directive
on each documented member and only declare the index file as a module.
Send a mapping of the plugins the master server has loaded to slaves
vice versa. Limit the plugins that may be loaded by instances to only
those that the master server has loaded.
Add config entry for the number of bits to use in the auto generate TLS
certificate for the master server and reduce it to 512 for the
integration test. This reduces the time needed to generate the
certificate in the integration test.
Add web_root option to the master server and use it create URLs for
resources hosted by it. This permits hosting the master server web
interface behind reverse proxy under a dedicated path.
Replace socket.io with plain WebSocket using the ws library as it
doesn't really provide any useful tools over plain WebSocket when it
comes to implementing reliable communication that works across
reconnects. The widespread browser support for WebSocket also means
it has little value to add for the web interface over WebSocket.
Catch errors thrown when constructing or initializing master pluigns and
wrap them in PluginError to ensure that they are properly reported as
plugin errors.
Replace current configuration mess with a trimmed down version of the
original vision of #200. Configs are collection of config groups that
have fields that can be set. These groups allow organizing the fields
as well as opertunity for plugins to add their own groups. By default
plugins have an auto generated group with the enabled field.
Close active connections and http servers during master shutdown and let
node exit on its own. If this fails with an error set output streams to
blocking and report it then shutdown with process.exit.
Also add double SIGINT handling to immediately shutdown.
Change Instance class to be a subclass of Link and refactor the
communication to and establisment of instances to use a virtual
connection between the slave and the instance. This is simplifies the
implementation of plugin communication for instances.
Replace InstanceRequest with a forwardTo option to Request which does
the task of forwarding in a much cleaner way.
Remove connection and client subclasses of Link and put the connection
logic into a "connector" class. The connector deals with sending
and receiving messages, handling the connection and reconnection of lost
connections and giving sequence numbers to messages.
This move the logic of the actual connection away from the link
sub-classes, which in turn means the connection should be a lot easier
to mock in tests.
Merge the events and requests categories in lib/link into messages and
use the class name of the message to determine which handler to call.
Also swaps the order of the arguments for forwardInstanceRequest to be
consistent with the rest of the lib/link code and fixes up the docs for
requests and events.
Add instance output event that is forwarded by the master server to
control connections that are subscribing to them. Add code subscribing
to the relevant instance output when dealing with instances in
clusterctl.
Rework client.js to support running multiple instances at once and be
managed remotely and implement the neccessary communication
infrastructure for this.
Due to circular dependencies on the implementation of this the master
branch is significantly broken after this.
