| # fork point of the current chain from canon) and fetches the
 | |
| # artifact.
 | |
| #
 | |
| # Since builds can be based on canon before the pipeline for the last
 | |
| # commit has finished, it is possible that the fork point has no
 | |
| # target map. To account for this, we will go up to 3 commits back in
 | |
| # time to find a map.
 | |
| #
 | |
| # If no map is found, the failure mode is not critical: We simply
 | |
| # build all targets.
