Stopping IOC boot on failure to load database

["Paduan Donadio, Marcio via Tech-talk" <tech-talk@aps.anl.gov>]

Hello, all.

 

We are thinking about creating a function in EPICS base like stopOnDbLoadError to be called before dbLoad* functions. The idea is to freeze the IOC boot with a message on the IOC shell or to completely abort, exiting. Alternatively, we could also place an additional optional parameter to the dbLoad* functions to have the same behavior.

 

What we intend with this is:

1.) bring the error to the attention of the responsible IOC engineer and,

2.) stop corruption of Autosave files due to missing PVs.

 

Do you think it would be something valuable to be added in an official EPICS release?

 

Thank you,
