Pull request overview
This PR migrates the Hex repository request handler to use the shared oidc.OIDCRegistry (introduced in #78) instead of maintaining its own OIDC credential map + mutex, aligning Hex with the newer collision-avoiding OIDC credential storage/matching approach used across handlers.
Changes:
- Replace per-handler
map[string]*oidc.OIDCCredential+sync.RWMutexwith a shared*oidc.OIDCRegistry. - Register Hex OIDC credentials via
OIDCRegistry.Register(...)(guarded byurl != ""to keep URL-scoped registration). - Authenticate requests via
OIDCRegistry.TryAuth(req, ctx)before falling back to staticauth-keyhandling.

Replace manual OIDC credential map and mutex with the shared OIDCRegistry type. Hex already used the full URL as the OIDC key, so this is a pure structural refactor with no behavior change. OIDC registration is guarded with url != "" to preserve the original URL-scoped behavior.

What
Migrate the Hex repository handler from manual OIDC credential map + mutex to the shared
OIDCRegistrytype introduced in #78.Why
Part of the phased migration to fix OIDC credential collisions when multiple registries share a host (#87).
Behavior changes
Credential selection is now deterministic. The old code iterated over a Go map (
map[string]*OIDCCredential), so with multiple OIDC credentials on the same host, which one matched was nondeterministic.OIDCRegistry.TryAuthuses longest path-prefix matching, ensuring the most specific credential always wins. This is the core fix for OIDC credential collision when multiple registries share a host #87.Host matching uses
strings.ToLowerinstead of IDNA normalization. The oldTryAuthOIDCRequestWithPrefixusedhelpers.AreHostnamesEqual(IDNAToASCII), whileOIDCRegistry.TryAuthuses lowercase comparison. This is acceptable because all real OIDC registries (Azure DevOps, JFrog, AWS CodeArtifact, Cloudsmith) use ASCII hostnames — no package registry uses internationalized domain names.OIDC registration guarded with
url != ""to preserve the original URL-scoped behavior and prevent fallback to host-only matching when the URL field is empty.Single-file diff, no test changes needed — existing OIDC tests cover Hex.
