This release fixes several bugs around bundle loading and error handling, and adds HTTP client caching to the Runtime for better connection reuse during bundle loading.

HTTP connection reuse across bundle polls

HTTP-based bundle loaders now share a per-service cache of long-lived HTTPClients (OPA.HTTPClientCache), so that TCP/TLS connections stay warm across polls and are reused when fetching bundles from the same service. Previously every load() call built a fresh HTTPClient and tore it down immediately after the call, paying a new TCP + TLS handshake on every poll.

Cached clients are keyed by service and validated on each load against the resolved HTTPClient.Configuration. A changed configuration (for example, a rotated certificate) transparently evicts and rebuilds the client. Closure-based config sources (.tls / .configuration) are pooled too, as long as the configuration they return is unchanged between loads.

New manual controls on OPA.Runtime let you force a rebuild after an out-of-band change to the HTTP config:

  • evictCachedHTTPClient(forService:)
  • evictAllCachedHTTPClients()

Note: the OAuth2 token request is not yet pooled (it still uses a one-off HTTPClient).

Breaking API changes

The OPA.HTTPBundleLoader protocol initializers gained a required httpClientCache: OPA.HTTPClientCache? parameter (on both the bundle and the discovery initializer). Types conforming to OPA.HTTPBundleLoader must add this parameter to their initializers.

The more basic OPA.BundleLoader protocol is unchanged, so custom non-HTTP bundle loaders are unaffected.
