IDE must support reconnecting after laptop has been slept/hibernated

Original issue is here.

Currently if the device goes to sleep when the laptop reawakes the IDE will have lost the connection to the backend.
The only option is to restart.

This scenario needs to allow auto reconnection preferably without requiring the complete rebuilding and re-execution of the project.

The backend should still have had all the results from the workflow execution so it should be possible to avoid running potentially very slow operations again from scratch.

Comments:

This is part of a much bigger task requiring trouble-less re-establishing of the connection. I will keep this ticket open, as one of the requirements. (Hubert Plociniczak - Feb 3, 2023)

Hubert Plociniczak reports a new STANDUP for the provided date (2023-07-07):

Progress: Continued investigating startup performance. Hit a roadblock with reported #7240. Logging service replacement is likely the next candidate for improvement. Being reading up the current implementation needed for reconnection after sleep. It should be finished by 2023-07-12.

Next Day: Next day I will be working on the #5197 task. Continue reading on re-connection and find missing pieces in LS.

Hubert Plociniczak reports a new STANDUP for yesterday (2023-07-10):

Progress: Have a small change that makes it easier to re-connect after laptop is woken up hibernation but it doesn't fix the problem. It looks like a) IDE doesn't attempt re-connection still b) (worse) it looses WebGL context after restart and the project view disappears. My change delays shutdown on LS when the last client disconnects, therefore one does not have to pay the price of startup all over again and IDE can re-use the port number of LS server that was originally assigned. That's probably all I can do on the LS-side. It should be finished by 2023-07-12.

Next Day: Next day I will be working on the #5197 task. Create a PR with LS change, create tickets for IDE.

I created a follow up ticket for IDE. On the LS side we are pretty much done, I think.

Progress: Created promised PR, figuring out how to add unit tests. Off most of the day. It should be finished by 2023-07-12.

Next Day: Next day I will be working on the #5197 task. Add unit tests, if possible.

Progress: Added unit tests that exercise the language server part. Further re-connection problems will need to be resolved on the IDE side. Verifyiing 7242Analysing visualization timeouts reported by Greg (likely a duplicate of an existing issue with jobs cancelling each other). Started looking into logging infrastructure. It should be finished by 2023-07-12.

Next Day: Next day I will be working on the #7253 task. Logging replacement.

So looks like things has gotten worse again in the past few weeks. LS still delays shutdown but somehow IDE claims to loose connection and never re-connects to the same port. Will need to investigate when it regressed. I'm guessing recreating webgl context might have something to do.
