[Nagiosplug-devel] Access to CVS as a developer

[Voon, Ton]

To be fair to Howard, he has raised 7 patches in SF. Subhendu has picked up
5 of these, of which he is waiting for a response for one of them. I've just
picked up the other 2, but need info on the check_ldap one.

As a team, we probably just need to be a bit more responsive to patches in
general - I'm sure this is making Howard v frustrated!

To get access, you submit patches one-by-one and develop neme
recognition and trust from the devlopers (It's not that hard, we're
not all that critical, but there has to some process, right). Declaring
your intent as you have done is a good start.

I made a few changes to support a limited dialog recently. I'm
interested to see where you're headed.

All the above bullets are of interest. Best to submit one patch per
plugin, however. We have to review them, and we're pretty limited on
time. Small bits are easier to digest.

I doubt this will ever be accepted. Contrib means 'unreviewd' and we
have no intention of changing thta meaning. What we want to do, in fact
the major goal for development after 1.4.0 is released is to move
plugins from conrib to core.

Also of interest.

Cool - a caution, however. We tend to like mutilpupose plugin more than
single purpose ones. So we have a single check_snmp, rather than
separate check_snmp_disk, check_snmp_memory, check_snmp_cpu, etc. The
finer-grained stuff is best handled as a command defintion using a
generic plugin. We distribute command.cfg to implement those sorts of
detailed checks. Command.cfg could be imporved substantially, but using
it in preference to separate plugins reduces the amount of duplicated
coding. That's just by word of caution, however, as I can't know
exactly what you have implemented from your descriptions.

Self-benefit is a good motivator - that's fine. You should also spend
some time watching and contibuting to discussions among the devlopers -
myself, Ton Voon, Subhendu Ghosh, Stanley Hopcraft, Jeremy Bouse, and
Ethan of course. We do almost all of our policy discussions in clear
public view, and that way we can be sure we're all headed in the same
direction should you decide you want to become a developer.

Patches should be against CVS head - as a deleoper, that is what you
work against and patch against. So start now, if that is your goal.

Hope that helps.
