Reconnecting issues #3224

Steps to reproduce with TS (Java is below):

Close your browser.
Delete previous Theia settings: rm -rf ~/.theia. (I am not sure this is mandatory.)
Clone, build and start Theia's backend for the browser. (e619393)
Set theia as your workspace root.
Open os.ts in Theia. Make sure your LS has started. You can verify with the CA.
Stop the backend.
Restart the backend.
You can see that something is already odd with the command registration.

yarn run start
yarn run v1.10.1
$ theia start

Close your browser.
Delete previous Theia settings: rm -rf ~/.theia. (I am not sure this is mandatory.)
Clone, build and start Theia's backend for the browser. (e619393)
Set eclipse.jdt.ls as your workspace root.
Open AbstractProjectImporter.java in Theia. Make sure your LS has started. You can verify with the CA.
Stop the backend.
Restart the backend.
You can see how many times the Java LS has started after the backend restart.

I was unable to verify if the same happens when only the connection is lost between the client and the server. So no backend stop. I set Offline in Chrome > Network, but it is smart enough not to report offline in Theia. Any ideas how we can check this?

akosyakov · 2018-10-19T08:38:45Z

Chrome does not apply connection profiles to WS-connections. One needs to use the system-level proxy to emulate connection issues, something like https://www.charlesproxy.com/

Thanks, @akosyakov. I will try this and update the thread.

kittaakos · 2018-10-19T08:46:45Z

I will try with https://mitmproxy.org. It is open source.

I was unable to verify if the same happens when only the connection is lost between the client and the server.

+1 on testing this properly.

However from my experience with using a backend from the other side of the ocean, in a setup where the network is sometimes flaky, I do relatively often experience the client disconnecting, and it seems to reconnect without causing visible issues.
