Remove `jupyter-channel-ioloop-comm.el`, `jupyter-comm-layer.el`, `jupyter-ioloop-comm.el`.
Remove the kcomm slot of a client, replace it with a kernel slot.
jupyter-server.el: Remove kernel communication related code.
Remove `jupyter-kernel-lifetime`.
* jupyter-kernel-manager.el (jupyter-kernel-lifetime): Do it. Update
all subclasses. All methods it defined no longer take a type. This
is in preparation of removing most of them altogether.
(jupyter-kernel-manager): Update doc.
* jupyter-kernel-process-manager.el
(jupyter-kernel-process): Update documentation.
(jupyter--kernel-died-process-sentinel): Remove type check.
* test/jupyter-test.el (jupyter-local-tcp-conn-info): Remove.
(jupyter-kernel-lifetime): Remove.
[conn] Have `jupyter-kernel-manager.el` re-direct to the new interface
* jupyter-kernel-manager.el
(jupyter-kernel-alive-p): Check that the kernel is
live, not an Emacs connection to it.
(jupyter-start-kernel)
[jupyter-kernel, jupyter-kernel-manager]: Use `jupyter-launch`.
(jupyter-shutdown-kernel) [jupyter-kernel-manager]: Use `jupyer-shutdown`.
(jupyter-kill-kernel) [jupyter-kernel]: Ditto. Remove a method
definition.
(jupyter-make-client): Use `jupyter-client`.
(jupyter-interrupt-kernel) [jupyter-kernel-manager]: Use `jupyer-interrupt`.
* jupyter-kernel-process-manager.el: Remove.
Don't add finalizer to cleanup process.
Cleanup is done in other ways, e.g. in
`jupyter--gc-kernel-processes`. Also it doesn't make sense to delete
a general kernel because the object that represents it in Emacs is no
longer accessible.
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.
