Fluxheim 1.5.22 Release Notes

Fluxheim 1.5.22 continues the crate-boundary preparation work for the later
1.6.x Pingora-removal line. Runtime behavior is intended to remain unchanged;
the focus is keeping cache/load-balancer domain logic behind Fluxheim-owned
interfaces before the HTTP runtime is replaced.

Changed

  • Load-balancer persistence key extraction now consumes a Fluxheim-owned
    request view trait instead of depending directly on Pingora request headers.
  • The existing Pingora RequestHeader support remains as an adapter at the
    load-balancer API boundary.
  • Managed-cookie persistence tests now run against a local Fluxheim request
    view, proving the persistence module can validate cookies without a Pingora
    request object.
  • fluxheim-web symlink-detection tests now use repository-local,
    component-validated test paths from the shared test-support helpers. This
    resolves CodeQL path-expression alerts in test setup/cleanup code without
    changing static-web runtime behavior.
  • Cleartext TCP health checks now use a Fluxheim-owned Tokio connect probe.
    TLS TCP health checks intentionally keep the existing Pingora transport
    connector so SNI/TLS handshake behavior stays unchanged in 1.5.22.
  • Cache request bypass, client revalidation, and range-selection decisions now
    run through a Fluxheim-owned cache request view. The root proxy cache module
    keeps a small Pingora RequestHeader adapter, so cache behavior is intended
    to remain unchanged while the cache crate owns more policy logic.
  • Cache response admission decisions for status, content type, response
    no-store policy, Vary handling, and range responses now live in the cache
    crate. The proxy cache module still exposes the same adapter functions for
    the existing Pingora response path.
  • Cache storage interface result enums for purge type and miss completion now
    live in the cache crate. Pingora PurgeType and MissFinishType conversion
    stays in the root adapter layer.
  • Range and slice cache-key component construction now uses a cache-crate
    helper, leaving the proxy cache module to adapt only Pingora's cache-key
    container.
  • UDP beta passive health now ignores local downstream drop conditions such as
    per-source response-rate limiting and oversized upstream responses. Only
    genuine upstream connectivity/timeout failures can contribute to passive
    ejection, and passive-ejection warning logs are rate-limited.

Compatibility

  • No configuration changes.
  • No load-balancer persistence behavior changes are intended for source-IP,
    URI, header, cookie, or managed-cookie persistence.
  • pingora-load-balancing and pingora-cache remain in the build graph for
    1.5.22; actual dependency removal is reserved for the 1.6.x line.
