I was wondering why there is different behaviour between PetscLogEventGetId() and PetscLogStageGetId()
PetscLogEventGetId() returns -1 if the event isn't found, whilst PetscLogStageGetId() throws an error if the stage isn't found. My use case is that within one of my custom preconditioners, I wanted to call PetscLogStageRegister() during the creation phase, but obviously I can only register the stage once. To enable multiple instances of the preconditioner to exist, I need to ensure that the stage is only registered once. Hence I would like to check for the existence of the stage prior to calling the register function. Is there currently a way to check for the existence of a registered stage? Cheers Dave
