Unstable behaviour of Jupyter-LSP - Losing connection #364

qTipTip · 2020-09-15T13:00:46Z

Hi!

First of all, thanks for an incredibly nice plugin.
I am having some issues with the stability of the plugin, and was hoping you could help me debug it further.
I'll try to describe my issues as detailed as possible.

Current Behaviour

Opening a new notebook

When initially opening a new notebook, with a new kernel, everything seems to initiialize properly. I observe the following messages in the developer console:

LSP: waiting for Untitled1.ipynb to fully load
notebook.js:79 LSP: Untitled1.ipynb ready for connection
adapter.js:307 LSP: will connect using language: python
connection_manager.js:159 LSP: connection requested {virtual_document: F, language: "python", document_path: "Untitled1.ipynb"}
connection_manager.js:94 LSP: Connection Socket {virtual_document: F, language: "python", document_path: "Untitled1.ipynb"}
connection_manager.js:171 LSP: Untitled1.ipynb python connected.
adapter.js:352 LSP: Adapter for Untitled1.ipynb is ready.
adapter.js:187 LSP: virtual document(s) for Untitled1.ipynb have been initialized
editor_adapter.js:24 No change obtained from CodeMirror editor within the expected time of 0.66s

At this point in time, the autocomplete seems to be functioning properly, and any modifications to the cell yields
things along these lines:

[LSP][Completer] Fetching and Transforming
completion_handler.js:132 [LSP][Completer] Token: {offset: 12, value: ".", type: undefined} {ch: 2, line: 1} {ch: 3, line: 1}

Losing Connection

Without forewarning, the LSP-plugin loses connection, with the following messages:

Connection lost, reconnecting in 0 seconds.

) [Error: Reader received error. Reason: Error during socket reconnect: code = 1006, reason = 
    at …, undefined, undefined]

connection_manager.js:32 LSP: Connection closed by the server 
(anonymous) @ connection_manager.js:32
a.emit @ index.js:10
(anonymous) @ index.js:10

fire @ index.js:10
(anonymous) @ index.js:10

fireError @ index.js:10
fireError @ index.js:10
(anonymous) @ index.js:10
e.onclose @ index.js:10
connection_manager.js:48 LSP: Connection unexpectedly disconnected

Failing to reconnect

Finally, the plugin gets stuck in this loop of the two following states:

default.js:1178 Connection lost, reconnecting in 0 seconds.
_reconnect @ default.js:1178
_onWSClose @ default.js:108
3adapter.js:259 LSP: Skipping document update signal: connection not ready

Expected behavior

I expect the LSP-plugin to reconnect, and resume working.

Hi @qTipTip, thank you for providing the detailed description. There are two issues:

the connection being lost (why?)
the extension not reconnecting properly (I will look into that!).

The language servers usually support a debug mode, but we have no way to trigger it from the UI - certainly a thing to think about. I would be curious to know:

when you start the jupyter lab from the command line, does it print out anything which could hint as to why is the server connection being lost?
does it happen quickly or after a long time?
do have the jupyter installed on the same machine that you are accessing it from (i.e. both jupyter and the browser on the same computer)?

krassowski · 2020-09-15T14:33:38Z

As to the error code 1006: https://stackoverflow.com/a/19305172/6646912

krassowski · 2020-09-15T14:35:44Z

Would you be able to check if it also happens with a different browser (e.g. Chromium or Firefox)?

qTipTip · 2020-09-16T12:57:09Z

Hi @krassowski !

Thank you for looking into this!
To answer some of your questions.

I am using jupyter-hub from a Kubernetes deploment (Zero to jupyterhub). Hence, the environment is built from a docker-image. I'll see if I can launch this docker image locally. The rest of the JupyterHub is responsive and functions as expected.
It happens usually within 10-15 seconds of the notebook starting. Up until then the functionality is as expected.
(See 1.) No, JupyterHub is deployed using Kubernetes, so not the same computer for both browser and jupyterhub. Maybe this has something to do with it?
I can confirm the issue happens with Brave, Chrome and Safari.

Let me know if there is anything else I can provide in terms of info.

Here is the packages installed in Docker.

krassowski · 2020-09-16T21:24:21Z

Thank you for the update - this helps a lot. I guess that it might be related to another JupyterHub-specific issue, #353.

qTipTip · 2020-09-17T09:25:23Z

Cheers!

In which respect is it related to #353?
It seems like that issue is related to users sharing a root-directory - in my case the users are each spawned into their own sandboxed environment, with the exception of a mounted shared folder.

Tell me if I can assist in any way :)

withsmilo · 2020-10-29T01:37:29Z

Same problem, too. @qTipTip , have you solved this problem? I also ran JupyterLab and jupyterlab-lsp in the docker environment similar to you.

JupyterLab 2.2.9
[email protected]
jupyter-lsp==0.9.2
python-language-server[Rope,Pyflakes,McCabe,pycodestyle]==0.35.1

@krassowski
In my case, the Jupyter workspace is mounted on the server running JupyterLab via NFS to provide home to users. Could this be the cause?

withsmilo · 2021-01-11T06:26:11Z

My issue dispappeared with @krassowski/[email protected]! Thanks!

JulianNotFound · 2021-01-13T05:40:15Z

It seems that this problem is not fully solved after updating to [email protected]. I have exactly the same problem when using jupyterlab-lsp in jupyterhub. The connection was lost after about 30 seconds no typing and didn't reconnect automatically.
Here is my information :

jupyterhub==1.3.0
jupyterlab==2.2.9
jupyter-lsp==0.9.3
[email protected]
python-language-server==0.36.2

rob-potter · 2021-01-17T01:42:50Z

Same issue, jupyterhub spawing jupyter labs, each user with their own home folder.

Happens sporadically for multiple users; can see LSP trying to reconnect after error 1006, but appears to give up after 6 attempts.
LSP continues to run, but no updates to detected errors.

Refreshing browser reconnects without issue.

In some cases, this happens for specific notebooks / files - usually for all. Newly opened files show LSP: Connect timed out for 5(python)

jupyterhub==1.3.0
jupterlab==3.0.3
jupyter-lsp==3.0.0
python-language-server==0.36.2

krassowski · 2021-02-11T02:16:31Z

I believe that the issue behind this is now fixed. In jupyter-lsp 1.1 we enabled pings on websocket to maintain the connection (https://github.com/krassowski/jupyterlab-lsp/pull/459) and in jupyterlab-lsp 3.1 we increased the timeouts for connection to the total of 5 minutes and 30 seconds (https://github.com/krassowski/jupyterlab-lsp/pull/479). I am reluctant to close this without your feedback as I have never experienced this issue, but I would be very keen to understand if the mentioned changes helped you.

May I suggest that you try with the latest version (jupyterlab-lsp 3.3.1 and jupyter-lsp 1.1.3 at the moment)?

qTipTip · 2021-02-11T08:51:13Z

Hey @krassowski!

That is great news! I am currently working on migrating our JupyterHub deployment to 1.3 with JLab 3.0. Will let you know!
