Two observations: - ‘proxy_cache_lock_timeout’ alone won't suffice to serialise requests; ‘proxy_cache_lock_age’ must also be set to an equally ridiculously long span. Otherwise, multiple requests will still be sent to ‘guix publish’ if they are more than 5s apart. Bleh. (The problem then becomes that clients will stall while the file is being cached, as explained by Mark. curl patiently waited.) - Say client A requests a nar from ‘guix publish’ (no nginx involved). If another client requests the same nar while A's still downloading, ‘guix publish’ will... silently drop A's connection? I was not expecting this. Kind regards, T G-R
