[tracecompass-dev] Race condition between CallSite analysis and UstDebug

[Arnaud Fiorini <fiorini.arnaud@xxxxxxxxx>]

Hello,

I changed with the following patch the UstDebugInfoSourceAspect 
(https://git.eclipse.org/r/c/tracecompass/org.eclipse.tracecompass/+/188654) 
to make it usable with the CallSite analysis.

Unfortunately, this patch works only some of the time because if the 
CallSite analysis is executed before the UstDebugInfo analysis, then the 
debug information is not in the state system and the CallSite analysis 
does not work.

Then I tried to do a blocking call to the aspect in the CallSite state 
provider but it will result in a deadlock if it is executed first, thus 
not solving the issue.

Is there any mechanism to make an analysis execute before another, or 
make Trace Compass execute another state provider while we wait on the 
current one ?

Thank you !

Regards,
Arnaud Fiorini
