[strongSwan-dev] [PATCH 0/3] Proposer error unifier for loggers

Hi Thomas,

Thanks for your patchset, looks promising. 

I didn't fully understand your requirements for such unique IDs, but
they of course might be helpful for different things.

The question I'm asking is: do you need these IDs across multiple
loggers, i.e. do we have to add this (a little exotic) unique ID
parameter to all loggers?

What about extending the logger_t interface by an optional "vlog" method
that takes the raw format string along with a va_list? This would allow
your logger backend to create/map these unique IDs just for itself
without letting other loggers bother with them, and then take
appropriate actions.

If required, we could even add a mechanism of some kind that would allow
your logger to re-feed log messages back to bus, and then to a different

That approach would be a little more flexible, as we are not bound to an
arbitrary 64-bit identifier, but can inspect the raw format string in
the logging backend. Does that sound reasonable?
