More descriptive error messages

[amikhalev]

Some errors we have encountered that are annoying to debug

• Missing config key
• Wrong type for config node
• Missing command

[PlasmaPower]

Proposal: add an "Expecting" log level. This would be for when something is expecting something else, and will crash when it does not exist. Examples include config and Kremlin.

[amikhalev]

So we are going to clutter the log with a bunch of those messages?

[PlasmaPower]

They can be hidden in TatorTool by default

[amikhalev]

There are better solutions than that

[PlasmaPower]

I think my solution solves other problems too, and generally helps with debugging.

[PlasmaPower]

Also, doing anything with YAML will be a pain.

@PlasmaPower Bump

[PlasmaPower]

@amikhalev Why don't you do this? I barely know where to begin.

[zachjs]

Status?

[PlasmaPower]

Missing command: done
All things yaml: not done

[amikhalev]

@PlasmaPower Another thing that would help is better stack traces, but I'm not sure if that is possible

[PlasmaPower]

@amikhalev For one thing, we could preload /lib/libSegFault.so for better seg fault messages.
