i think that most functions return '-1' in case of an error, but i'm not sure how many document this. Adding a statement to every available module functionis probably not the best way of dealing with this issue. Any idea where this could be documented instead?
That's food for thought. In this case I can imagine more error codes though, like -2 for database error, -1 for "not found" and other codes...
Hi Olle,
sure, this is another point. But trying to agree to one scheme for error codes for all this different module functions won't be probably easy. Why do you think it would make sense to handle DB errors differently in the script then any other errors? This informations are visible in the logs after all.
Well, there's a big difference if we have a negative reply from the database or no reply at all from the database because it's down. In general, I'm wondering how to catch that state in the Openser config without reading log files - maybe the error_route could catch these so I could send a warning somewhere. That would be generic enough and handled from the db subsystem.
We already have apps that return various error codes that are "reserved", like the auth functions and the t_relay function.
