Upstream: consistently initialize explicit upstreams. When an upstream{} block follows a proxy_pass reference to it, such an upstream inherited port and default_port settings from proxy_pass. This was different from when they came in another order (see ticket #1059). Explicit upstreams should not have port and default_port in any case. This fixes the following case: server { location / { proxy_pass http://u; } ... } upstream u { server 127.0.0.1; } server { location / { proxy_pass https://u; } ... } but not the following: server { location / { proxy_pass http://u; } ... } server { location / { proxy_pass https://u; } ... } upstream u { server 127.0.0.1; }
