Scott Wittenburg 6239198d65 Fix cause of checksum failures in public binary mirror (#32407) ... Move the copying of the buildcache to a root job that runs after all the child pipelines have finished, so that the operation can be coordinated across all child pipelines to remove the possibility of race conditions during potentially simlutandous copies. This lets us ensure the .spec.json.sig and .spack files for any spec in the root mirror always come from the same child pipeline mirror (though which pipeline is arbitrary). It also allows us to avoid copying of duplicates, which we now do.		2022-09-01 15:29:44 -06:00
