daemon/api: fix legacy D-Bus API and add coverage
Browse files Browse the repository at this point in the history
Fix logic to make sure we check if the refspec is of type `ostree://`
even when it's explicitly specified. Also fix `Deploy` in the case where
we didn't just `Download` the RPM diff by adding a new @Checksum
parameter to the higher-level API.

Finally, add a basic test for the `GetCached*RpmDiff` APIs so we have at
least *some* coverage. This is also good prep for making sure we don't
break anything when we convert those APIs to use the more efficient
pkglist metadata. The tests completely ignore the `DownloadRpmDiff`
paths for now though.

Closes: coreos#1250
