I'm picking up two loose threads from #varnish-hacking:
VDI_Resolve
-----------
I'm working on a director which needs to resolve another (layered) director
argument, so I'd prefer to have basically VDI_Resolve in VRT. Proposed
signature:
VCL_BACKEND VRT_Resolve(VRT_CTX, VCL_BACKEND)
the VCL_BACKEND argument would be used instead of bo->director_req.
Also I'd want to move the logging calls to the caller.
avoid director healthy() callback
---------------------------------
To avoid code duplication, I think core code should basically call
VRT_Healthy(VRT_Resolve(ctx, backend));
if there is no healthy callback. IMHO this would make much more sense than just
asserting a director without a healthy callback to be healthy always.
Thx, Nils
