Crystal clear, looking inside all the builds I see that all the repos
associated with a project (in this case
openstack-tripleo-heat-templates) have in common the last part after the
underscore (in this case _cbd0900e).
This is expected, because there are several RPM packages created from a single source
GitHub repo. The last part after the underscore is the short git hash for the distgit
(a.k.a. repo where the spec file is), in this case
https://github.com/rdo-packages/tripleo-heat-templates-distgit/commits/rp....
What's the criteria with this? Which rules define which
modifications
should be in a repo? And, most of all, how different repos are put
together to be tested by a promotion pipeline? Are they always tested as
single?
In DLRN, repos are incrementally updated, something like:
- The repo mentioned above includes the last version of openstack-tripleo-heat-templates
(let's assume it is 1.0.1), and the last versions of every other package built before
(let's assume we have foo 1.0.0 and bar 1.1.0)
- When the next package is built (let's say foo 1.0.1), its repo will include the
latest version of every package (so foo 1.0.1, bar 1.1.0 and t-h-t 1.0.1).
So, every repo created after building the package we're interested in, includes the
package version we want (or a later one).
Finally, the promotion pipeline takes the latest consistent repo, which includes the
latest version of every package already.
Hope this questions are clear :)
Absolutely :).

In the promotion pipeline how can one search for the status of his repo?
In the Jenkins promotion pipeline, the first job is named
"rdo-promote-get-hash-master", and it finds the hash. For the latest (failed)
execution, it was
https://ci.centos.org/job/rdo-promote-get-hash-master/461/console, and
the value we see assigned as NEW_HASH includes the commit we were trying to promote.

That's clear too.
