If, in the life of a recipe, a SRC_URI change hash without changing name, the mirroring test for that recipe fails. For example, it happens for upstreams which does not put a version in their filenames (see this meta-oe fix[0] This is because the DL_DIR -> https://downloads.yoctoproject.org/mirror/sources/ deploy process uses "rsync --ignore-existing" (as per [1]). The new archive won't be copied to yp.org (overwriting the old one). So, in the mirroring test, the archive will not match. This is most likely by design: the old archive may be referenced by other branches (ie stables) and a new archive being uploaded should not break their mirroring tests. I wonder if we could somehow address the mirrored files by their hash (which we know from the recipe) instead of the filename (which might have multiple possible content).

We should document why the infrastructure works this way.
