Implement the minimal changes to the local filesystem storage driver and feed them through the distributed storage driver.
Create a digest package which contains digest_tools and checksums.
Fix the tests to use the new v1 endpoint locations.
Fix repository.delete_instance to properly filter the generated queries to avoid most subquery deletes, but still generate them when not explicitly filtered.
Before this change, we used extremely inefficient outer joins as part of a single query of lookup, which was spiking our CPU usage to nearly 100% on the query. We now issue two separate queries for popularity and action account, by doing a lookup of the previously found IDs. Interestingly enough, because of the way the queries are now written, MySQL can actually do both queries *directly from the indicies*, which means they each occur in approx 20ms!
Verified by local tests, postgres tests, and testing on staging with monitoring of our CPU usage during lookup
This authentication system hits two HTTP endpoints to check and verify the existence of users:
Existance endpoint:
GET http://endpoint/ with Authorization: Basic (username:) =>
Returns 200 if the username/email exists, 4** otherwise
Verification endpoint:
GET http://endpoint/ with Authorization: Basic (username:password) =>
Returns 200 and a signed JWT with the user's username and email address if the username+password validates, 4** otherwise with the body containing an optional error message
The JWT produced by the endpoint must be issued with an issuer matching that configured in the config.yaml, and the audience must be "quay.io/jwtauthn". The JWT is signed using a private key and then validated on the Quay.io side with the associated public key, found as "jwt-authn.cert" in the conf/stack directory.
Fixes two issues found with our LDAP handling code. First, we now follow referrals in both LDAP calls, as some LDAP systems will return a referral instead of the original record. Second, we now make sure to handle multiple search result pairs properly by further filtering based on the presence of the 'mail' attribute when we have multiple valid pairs. This CL also adds tests for all of the above cases.
Currently, we use the Quay username via `verify_user` when we go to create the encrypted password. This is only correct if Quay has not generated its own different username for the LDAP user, and fails if it has. We therefore add a new method `confirm_existing_user`, which looks up the federated login for the LDAP user and then runs the auth flow using that username.
