Fixes #60
When the remote asset API is used with Bazel as a client, and
--experimental_remote_downloader_propagate_credentialsis provided, the bearer tokens are included as qualifiers, however since these change regularly and frequently, resources requiring auth not only rarely get cache hits, but also they result in identical copies of their resources populating the asset store cache.Fix by filtering out auth and http header qualifiers before sending the asset ref down to the asset store.
Note that I'm looking at this PR from my own personal narrow perspective and might be overlooking a subtle detail/requirement... Other solutions I can think of would be to make the digest based entirely on
checksum.sriif that qualifier is provided, being more specific to include onlyhttp_header_url:*:Authorizationinstead ofhttp_header_url:*qualifiers, or making this a configuration parameter.I've verified that this fixes my cache churn issues in my deployment.
Also apologies if I missed it but I couldn't find contribution instructions so feel free to point me to them if things need to be fixed up.
