Previously `spack buildcache push --only=package` errored in the OCI case, but it's been requested that OCI can be used as pure storage w/o the need for runnable container images. This commit makes it so that 1. manifests refer only to runtime dependencies that were selected to be pushed 2. failure to upload a blob among the selected specs does not prevent a manifest/tag to be created for dependents: they just don't refer to the missing blob as a layer/dependency This fixes the following issues: 1. dependents of non-redistributable specs can now be pushed to oci build caches without error 2. failure to upload one tarball does not cause cascading failures for dependents whose tarballs do upload succesfully -- so it's better best-effort behavior 3. for some people uploading with deps caused a massive amount of fetches of their manifests (which certain registries count as a download of an image, even though their layers are not fetched) -- being able to specify --only=package reduces the number of fetches. |
