Detect index out of sync [message #1859466]

Hi

In case, my application was terminated not properly (e.g. crash), the persisted index (ResourceDescriptions) may no more match the actual state.

As a solution - to bring the application again into a proper working state - a full build needs to be triggered.

Now I would like to automate this, so the user does not need to know about this.
Is there a way to detect this situation?

regards Frank

@frank are you talking about eclipse usecase?
emf based persister already should do this.

Yes, in Eclipse based RCP.

Thanks for the pointer.
Indeed the EmfBasedPersister is triggered.
Now I understood that it does not really do a build, it just makes the build state to be removed.
I needed to add an incremental build to ensure the index is completely valid.
At least, this solved the bug/problem I am working on.
Is this expected? (the extra needed incremental build)

scheduleRecoveryBuild();
This should already be called
Does this not work ?

Yes, it is always called. But in org.eclipse.xtext.builder.impl.BuildScheduler.scheduleBuildIfNecessary(Iterable<IProject>, IBuildFlag...) it goes into builderStateDiscarder.forgetLastBuildState and that's it.

What I try in my application:
import a project.
Use it -> OK
Terminate the application forcefully, reopen
Use the same project -> it fails
Terminate the application forcefully, reopen
run incremental build before use, then use it -> OK

Have no background why it is done this way
Maybe you can patch the forget last build state out
And do a full build instead
