It is impossible to test new stacks with plugins ^(
eclipse-che/che#12944

[tsmaeder]

@tolusha could you explain why this prevents testing?

[tolusha]

It doesn't prevent testing anymore. I've found workaround by testing commands without plugins.

[tolusha]

It is possible to test commands with python stack which doesn't use sidecars.

The bug is reproduced when we have at least one active remote plugin, so I tested it with typescript plugin.
We create one RPC per host, so at least one rpc for typescript plugin and one for 'main' host. Next we initialize CheApiProvider - so in my case - twice - for each rpc - as result I get two proxy.

root INFO onMessage {"pluginID":"vscode_typescript_language_features","content":["{"type":1,"id":"20","proxyId":"CheTask","method":"$getTaskInfo" ,"args":[0]}"]}

As I can see from logs, requests for runtime info of a task are redirected on remote plugin side (typescript plugin in my case).

I'm not sure about current behavior - is it OK that remote plugin creates own proxy for this case and tries to handle all requests?
If so, I'll provide PR which will handle case when we have a few proxy and should analyze responses from them.
@benoitf could you take a look

[slemeur]

Who is handling this issue?

[RomanNikitenko]

@slemeur I'm testing some fix for @eclipse-che/theia-plugin-ext side and going to provide the PR.
But it would be great to get answer on question above - may be the problem is deeper and we can have another potential issues
