Code completion is leading to validation execution in language server [message #1856398]

Code completion is leading to validation execution in language server isn't bug ?

why we do execute validation when user request only code completion?

In LanguageServerImpl we do have method
public void didChange(DidChangeTextDocumentParams params) which will get triggered when we change resource in client , for IncrementalBuilder its always a new build request.

it would really help if you can give more context in your lsp questions if you expect to get an sufficient answer
can you provide a call stack where the vaidation is done

@Christian Dietrich Thank you for quick reply.

To answer your question
In IncrementalBuilder we have a method validate(Resource resource)

call stack : LanguageServerImpl[didChange->toBuildable]
WorkspaceManager[didChangeTextDocumentContent->didChangeFiles] ->BuildManager [submit-->internalBuild] IncrementalBuilder[launch]

I have attached debug call stack for reference.

does this information is sufficient?

As per my understanding this is a direct invocation of method public void didChange(DidChangeTextDocumentParams params) from client what i meant is through rpc. content assist execution is in separate thread.

but if you change the file you change the file? so the client tells the server that the file changed.
so you expect didChange not to trigger validation. but how do you want to trigger validation then?

@Christian Dietrich

validation should be triggered on save ? LanguageServer -> public void didSave(DidSaveTextDocumentParams params) we have empty implementation here.

we do live validation. thus validation is triggered on didChange and not on didSave.
of course you can subclass and change that.
