This was mainly used when having to refresh the websocket connections
to a server after a REST request. Refreshing the websocket
connections is now handled internally to the connection of a
`jupyter-server`.
* jupyter-server-kernel.el
(initialize-instance): Add `kernel-ids` variable, modify it when
connecting/disconnecting kernel channels to the server's websocket
connections. When starting the subprocess that handles websocket
connections, re-connect any previously connected kernels.
(jupyter-server--refresh-comm): Remove.
(jupyter-server-kernel-connected-p): Remove.
(jupyter-api-request): Use `jupyter-start`/`jupyter-stop` when
refreshing websocket connections.
(jupyter-server--connect-channels): Use `jupyter-ioloop-wait-until`.
(jupyter-connection): Remove `jupyter-server-kernel-connected-p`
call.
* jupyter-kernel-process.el
* jupyter-server-kernel.el (jupyter-kernel): New method.
* jupyter-kernel.el (jupyter-kernel): Convert. Load files that handle
keywords and re-dispatch when ARGS does not have any connection
info. Document behavior.
* test/test-helper.el (jupyter-test-with-kernel-client)
* jupyter-server.el
(jupyter-connect-server-repl)
(jupyter-server-start-new-kernel): Use `jupyter-kernel`.
The new files added in this commit will eventually replace the manager
and kernel classes and favor struct types to represent kernels instead
of classes. A kernel manager was a concept ripped from the
jupyter/jupyter_client reference implementation.
In Emacs the concept makes the client implementation more complicated
and is replaced by functions that manage the lifetime of a kernel:
`jupyter-launch`, `jupyter-shutdown`, and `jupyter-interrupt`.
* jupyter-kernel-manager.el
* jupyter-kernel-process-manager.el
* jupyter-server.el
* test/jupyter-server-test.el
* test/test-helper.el: Make `jupyter-kernel`, `jupyter-server-kernel`,
and `jupyter-kernel-process` private classes. The new files below
use the public names, but as structs now.
* jupyter-kernel.el
* jupyter-kernel-process.el
* jupyter-server-kernel.el: New files.
