* jupyter-comm-layer.el
(jupyter-comm-initialize): Remove default method. This is in
preparation for moving over to classless communication.
* jupyter-channel-ioloop-comm (jupyter-connection): Require.
(jupyter--proxy-channel): New type.
(jupyter--make-channel-group, jupyter--channel-alive-p)
(jupyter--start-channel, jupyter--stop-channel)
(make-jupyter-async-connection): New functions.
(jupyter-channel-ioloop-comm): Remove `ioloop-class` slot, update all
callers. Remove `channels` slot, update all setters and
references. Add `conn` slot which holds a `jupyter-connection`.
(jupyter-comm-initialize): Initialize the `conn` slot to the
connection returned by `make-jupyter-async-connection`.
(jupyter-comm-start, jupyter-comm-stop)
(jupyter-comm-alive-p, jupyter-comm-id, jupyter-channel-alive-p)
(jupyter-stop-channel, jupyter-start-channel): Replace the body of these
functions with their equivalents in `conn`.
* jupyter-kernel-process-manager.el
(jupyter-make-client): Update `jupyter-channel-ioloop-comm` call.
* jupyter-repl.el:
(jupyter-connect-repl): Ditto.
* test/test-helper.el
(initialize-instance) [jupyter-echo-client]: Ditto. Replace setting of
`channel` slot with setting the `conn` clot.
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.
This is in preparation for merging `jupyter-command-kernel` and
`jupyter-spec-kernel` into just the `jupyter-kernel-process` class.
* jupyter-env.el
(jupyer-session-with-random-ports): New function.
* jupyter-kernelspec.el
(jupyter-expand-environment-variables)
(jupyter-process-environment)
(jupyter-kernel-argv): New functions.
* test/jupyter-test.el
(jupyer-session-with-random-ports)
(jupyter-expand-environment-variables)
(jupyter-process-environment)
(jupyter-kernel-argv): New tests.
* jupyter-kernel-manager.el (jupyter-kernel): Set `spec` slot type to
`jupyter-kernelspec`.
(jupyter-kernel-name):
* jupyter-kernel-process-manager.el: Update all accessors.
* jupyter-kernelspec.el: Add `jupyter-kernelspec` struct type.
* jupyter-repl.el:
* jupyter-server.el:
* ob-jupyter.el:
* test/test-helper.el: Update all kernelspec using functions to use
the new type.
`default-directory` is already set according to :dir when executing a
source block. This prevents `org-babel-expand-body:jupyter` from
attempting to re-expand the value of the :dir header argument.
See #302.
Replace it with a handler function passed to `jupyter-ioloop-start`.
* jupyter-ioloop-comm.el: Do it.
* jupyter-channel-ioloop-comm.el: Do it.
* jupyter-channel-ioloop-comm.el: Do it.
* jupyter-ioloop.el: Do it. Update comments and doc.
(jupyter-ioloop--delete-process): Remove. It was used to perform
cleanup when the object used for dispatching to a handler method was
garbage collected. Since we no longer rely on having an object for
dispatching, preferring just a function to call, its not needed.
(jupyter-ioloop--make-filter): Fall back to calling handler function
instead of `jupyter-ioloop-handler`. Only handle ioloop start/stop
events internally. This means we can remove the check for those in
`jupyter-ioloop-comm`.
* test/jupyter-test.el: Update tests to take into account above
changes.
* ob-jupyter.el
(org-babel-jupyter-server-session)
(org-babel-jupyter-parse-session): Convert to method and re-implement
with :extra methods.
* test/jupyter-server-test.el
(org-babel-jupyter-server-session): New test.
* test/jupyter-test.el
(org-babel-jupyter-parse-session): Move test of server based sessions
to the new test.
but first...
* jupyter-base.el: ...idle-received-p -> idle-p for jupyter-request objects
* jupyter-client.el: ...then, do it.
* test/jupyter-test.el: Do it.
These will be used in future commits.
* jupyter-client.el (jupyter-idle-sync)
(jupyter-add-idle-sync-hook): New functions.
* test/jupyter-test.el (jupyter-idle-sync): New test.
The following changes are made:
jupyter--run-handler-p -> jupyter--request-allows-handler-p
jupyter--handler-dispatch -> jupyter--run-handler
* jupyter-client.el: Do it.
* test/jupyter-test.el: Do it.
This commit adds the function `org-babel-jupyter--babel-map` and some
auxiliary functions to simplify the code for source block
overriding. The old implementation was very hard to follow, these
changes should hopefully make the code more readable.
* ob-jupyter.el (org-babel-jupyter--override-restore-header-args)
(org-babel-jupyter--override-restore-src-block): Remove.
(org-babel-jupyter--babel-vars): New variable.
(org-babel-jupyter--babel-op-symbol)
(org-babel-jupyter--babel-var-symbol)
(org-babel-jupyter--babel-map): New functions.
(org-babel-jupyter-override-src-block)
(org-babel-jupyter-restore-src-block)
(org-babel-jupyter-make-language-alias): Use them.
It is replaced with `jupyter-map-mime-bundle` which is a function.
* jupyter-base.el (jupyter-loop-over-mime): Remove.
(jupyter-map-mime-bundle): New function. Update call sites of the
removed function, with calls to this function.
(jupyter-normalize-data): Return a mime bundle, a property list with
:data and :metadata keys. Update all callers.
* jupyter-mime.el (jupyter-insert): Updated to take into account the
previously mentioned changes.
* jupyter-org-client.el (jupyter-org-result): Ditto.
* test/jupyter-test.el (jupyter-loop-over-mime): Rename to
`jupyter-map-mime-bundle` and update the test to consider it.
The `jupyter-zmq-channel-comm.el` file was more of an experiment and
is unused. It also causes failures on Emacs 27 due to missing
`thread-alive-p` function in 27.
* jupyter-zmq-channel-comm.el: Remove.
* test/jupyter-test.el: Remove the related `require`. Re-work tests
that used `jupyter-zmq-channel-comm` to not use it.
In `org-babel-jupyter-initiate-session-by-key`, the function to
disassociate a client from a :session was added to the
`current-buffer`s value of `kill-buffer-hook` but it should be added
to the REPL buffer's value of that hook.
fixes#240
* ob-jupyter.el
(org-babel-jupyter-initiate-session-by-key): Add to the local value of
`kill-buffer-hook` in the REPL's buffer.
* test/jupyter-test.el
(org-babel-jupyter-initiate-session-by-key): New test.
Converting to lowercase was done arbitrarily. So that one could write
`(jupyter-lang wolfram-language)` instead of
`(jupyter-lang Wolfram-Language)`.
fixes#241
* CHANGELOG.org: Add note.
* README.org: Update relevant sections.
* jupyter-base.el (jupyter-canonicalize-language-string): Do it.
* ob-jupyter.el (org-babel-jupyter-aliases-from-kernelspecs):
The test for #219 isn't really testing the root cause of the bug, only a
symptom. And it doesn't catch anything on Emacs < 27.
* test/jupyter-test.el (jupyter-repl-issue-219): Skip on Emacs < 27
* jupyter-server.el (jupyter-ioloop, jupyter-server-ioloop): Remove requires.
(jupyter-server): Don't subclass `jupyter-ioloop-comm`.
(jupyter-server--connect-channels, jupyter-server--refresh-comm): Only do
something when the SERVER argument is a `jupyter-comm-layer`, i.e. a
`jupyter-server-ioloop-comm`. We don't check for that class directly since we
would end up requiring ZMQ.
(jupyter-comm-start) [jupyter-server-kernel-manager]: Use the right subclass of
`jupyter-server-abstract-kcomm` depending on if the `jupyter-server` object is
using ZMQ for communication.
(jupyter-server-make-instance): New function. Returns a `jupyter-server`
instance (a `jupyter-server-ioloop-comm`) that uses ZMQ if
`jupyter-server-use-zmq` is non-nil, and a plain old `jupyter-server` instance
otherwise.
(jupyter-current-server): `jupyter-server` -> `jupyter-server-make-instance`.
* ob-jupyter.el (org-babel-jupyter--server-repl): `jupyter-server` ->
`jupyter-server-make-instance`.
* test/test-helper.el (jupyter-test-with-notebook): `jupyter-server` ->
`jupyter-server-make-instance`.
* test/jupyter-test.el: Move all zmq related tests (and code) to
`test/jupyter-zmq-test.el`, add a `zmq` tag to the tests.
* test/test-helper.el (zmq, jupyter-zmq-channel-ioloop)
(jupyter-zmq-channel-ioloop-comm): Remove requires.
(jupyter-test-ioloop-eval-event, jupyter-test-channel-ioloop)
(initialize-instance) [jupyter-echo-client]: Remove uses of ZMQ by using
a `jupyter-mock-comm-layer` for the `kcomm` slot.
(jupyter-test-zmq-sockets): Move to `test/jupyter-zmq-test.el` along with all
related code.
* test/jupyter-zmq-test.el: Add tests moved from `test/jupyter-test.el` and all
related code.
* test/jupyter-server-test.el (jupyter-server): Replace test with one that
takes into account a `jupyter-server`s changed implementation. Before, in
addition to talking to a kernel via the REST API, it managed a set of websocket
connections in a separate process. Now, those websocket connections live in
the current Emacs process.
Ensure that `jupyter-test-with-notebook` uses a `jupyter-server` object by
let binding `jupyter-server-use-zmq` around its call.
(jupyter-server-ioloop-comm): New test with the same body as `jupyter-server`
had before this commit. Skip the test unless `jupyter-server-use-zmq` is
non-nil. Rename `jupyter-server-kernel-comm` to
`jupyter-server-ioloop-kernel-comm`.
The following changes are made:
`jupyter-initialize-connection` -> `jupyter-comm-initialize`
`jupyter-connect-client` -> `jupyter-comm-add-handler`
`jupyter-disconnect-client` -> `jupyter-comm-remove-handler`
`jupyter-comm-client-loop` -> `jupyter-comm-handler-loop`
* README.org: Do it.
* jupyter-channel-ioloop-comm: Do it.
* jupyter-client.el: Do it.
* jupyter-comm-layer.el: Do it.
(jupyter-comm-layer): Rename `clients` slot to `handlers`. Update all uses.

* jupyter-repl.el: Do it.
* jupyter-server.el: Do it.
* jupyter-zmq-channel-comm.el: Do it.

* test/jupyter-test.el: Do it.
* README.org: Add notes on behavior when a kernel's language name has spaces
and uppercase characters.
* jupyter-base.el (jupyter-canonicalize-language-string): New function.
* jupyter-client.el (jupyter-kernel-info): Use it.
* jupyter-kernelspec.el (jupyter-available-kernelspecs): Use it.
* ob-jupyter.el (org-babel-jupyter-aliases-from-kernelspecs): Use it.
* test/jupyter-test.el (jupyter-canonicalize-language-string): New test.
Since we are using keyword to represent channels on the client level, use a
plist of channels on the comm layer level instead of channel slots. This allows
us to remove `jupyter-comm-channel` and simplify the relevant code somewhat.
So as to further generalize and separate out the abstract kernel manager class
from its various implementations.
* jupyter-kernel-manager.el (jupyter-meta-kernel): Fix documentation.
(jupyter-kernel-process, jupyter-command-kernel, jupyter-spec-kernel):
Move related functions and methods to `jupyter-kernel-process-manager.el`
(jupyter-kernel-manager-base): Remove class.
(jupyter-kernel-manager): Re-purpose class as the base class of all kernel
managers. The class corresponding to the old functionality is now named
`jupyter-kernel-process-manager`. Move all related functions and methods for
`jupyter-kernel-process-manager` to `jupyter-kernel-process-manager.el`.
* jupyter-kernel-process-manager.el: New file.
* jupyter-repl.el: Require `jupyter-kernel-process-manager` instead of
`jupyter-kernel-manager`.
* jupyter-server.el (jupyter-server-kernel-manager): Inherit from
`jupyter-kernel-manager` instead of `jupyter-kernel-manager-base`.
* test/jupyter-test.el (jupyter-kernel-lifetime)
(jupyter-command-kernel): Use `jupyter-kernel-process-manager` instead of
`jupyter-kernel-manager`.
* test/test-helper.el: Require `jupyter-kernel-process-manager` instead of
`jupyter-kernel-manager`.
See #161
* jupyter-rest-api.el (jupyter-api--delete-cookie):
(jupyter-api-delete-cookies): New functions.
* jupyter-server.el (jupyter-gc-servers): Do it.
* test/jupyter-server-test.el (jupyter-api-delete-cookies): New test.
