RFC: DTrace probes for debugging or testing in userland programs

[Adrian Chadd]

Hi,

I'd love to see a unified-ish logging API for FreeBSD applications. I
always end up reusing some C code I have here that I based on some
Squid style logging API in ages past. I could always polish it up and
put it up for review.

I'm not a big fan of requiring dtrace to use it though. On a lot of
the embedded systems dtrace varies from "it's very big" through to "we
don't have enough RAM/flash to do this".

So although I like the sentiment, I don't think using dtrace for
program logging is the right answer.  I like what apple did to wrap
the program logging stuff so people didn't just write their own
libraries (hi!) and so there's a unified-ish way to interact with
apple programs. I think we could do with that.

Thanks,
