Yes, this race is possible if the time it takes ELN to complete the
rebuild of the first package is longer than the time it takes the
second package to build and then also trigger the ELN build. It's
unlikely to occur often, but it is a possibility. I'm not sure how to
avoid it since without a side-tag we can't know which builds might be
dependent on one another.
For those grouped builds that use a side-tag, we're going to be
monitoring those and rebuilding them in the same order as they are
submitted. We can also add a waitrepo to our behavior to ensure that
we don't start newer builds before the prior ones succeed.
Thanks for bringing this up!
I think I have another build ordering issue. Recently libevent had a
soname bump and deps were built in a side tag. However, in ELN
openmpi-4.0.5-2.eln103 (which was the release bump for the libevent
rebuild) was built before libevent-2.1.12-2.eln103 was. Now I'm getting
spammed every couple of hours with netcdf and vtk ELN build failures due
to broken deps on libevent (and others).
Are we now stuck with bumping the release for openmpi again for the ELN
