Subject: ceph-dev-pipeline: only skip compilation when every enabled backend has the build
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=c43e22ac5acbd59689fef7cb6153ccd8607cecea;p=ceph-build.git

ceph-dev-pipeline: only skip compilation when every enabled backend has the build

shouldSkipCompilation() treated the existence checks as an OR: if
either Chacra or Pulp already had the build, compilation was skipped
entirely -- which also skipped the upload to the backend that was
missing it.  Observed with PULP_UPLOAD and CHACRA_UPLOAD both enabled:
pulp had the distribution, the chacra check came back empty, and the
cell skipped straight past both uploads, so chacra never received the
build.

Skip compilation only when every enabled backend already has the build
(disabled backends don't count), and when compilation does run because
one backend was missing, skip the upload stage of the backend that
already had it (unless FORCE) so packages aren't blindly re-pushed.
