[Buildbot-devel] Multiple upstreams for Dependent scheduler

[Andy Salnikov]

Hi,

I'm trying to setup new build system with buildbot and one thing that I'd
like to do for it is to run some action when "all" builders have finished.
Dependent scheduler seems to the kind that I need, but its limitation
is that it only depends on a single upstream scheduler while I want to
wait for multiple schedulers (running in parallel) to finish. Would it be
possible to extend the Dependent scheduler to support multiple upstream
schedules (with an "AND" logic)? I gather this could be useful for other
people as well, I of course could (and maybe would) implement my own
scheduler but having this in standard code base could be useful.

Another thing that I'd like to have in Dependent scheduler is "forwarding"
of the properties (all or selected subset of them) from the upstream
scheduler. I have a special nightly scheduler which defines some special
properties used throughout the system. With that I had also subclass a
Dependent scheduler to pass properties defined in the nightly scheduler
down to the builders. Simpler solution that does not need subclassing
would be preferable to me.

Thanks,
Andy
