ValidationException on configuration change #70

Closed Virtlink closed 3 years ago

Virtlink commented 3 years ago

Summary

I changed the .cfg of my Tiger language to use JSGLR2 instead of JSGLR1, rebuilt and restarted the LWB, and PIE fails to compile the new language, giving this error:

ValidationException: Visited task with same key was required with different input in same session.

What you did

I changed the parser configuration of my Tiger pure Spoofax 3 project from:

parser {
  default-start-symbol = sort Module
  variant = jsglr1
}

to

parser {
  default-start-symbol = sort Module
  variant = jsglr2 { }
}

I did some other things in between, which is why I rebuilt and restarted the LWB. The Tiger language was loaded again, and PIE gave the above error on build.

What you expected to happen

I expected PIE to recognize that the configuration has changed, and rerun the appropriate tasks. I suspect PIE has serialized some state that is now incorrect.

What actually happened

I got this error:

Although I could not reproduce the problem, I could imagine how this can happen. Should be solved in https://github.com/metaborg/spoofax-pie/commit/a0a15bd0704738fb4b6874a0ebd9fa0bf2ab5c8e
