Describe the bug

I couldn't disable my substitor config even because I couldn't switch!
The problem was that my server ran an ancient nix daemon (2023) which is incompatible with recent lix.

I'd expect it to just continue after getting 500 errors from a substitor

Steps To Reproduce

you cna reproduce by making a faulty substitor with netcat:

while true; do echo -e "HTTP/1.1 500 Internal Server Error\r\nContent-Length: 0\r\nConnection: close\r\n\r\n" | nc -l 80; done

Then you just set your normal nix config to use that substitor and it'll get 500 errors on any substitute attempt

Expected behavior

It should figure out the substitor is faulty and at least disable it for the current build.
Having a single substitor fail breaking my entire build system isn't acceptable.

Hello, world!

so we'd consider your problem fixed, but we probably should not be retrying the same substituter quite this often if it's failing

running your reproducer on 2.95 we get this instead: ``` ❯ nix run --store /tmp/store nixpkgs#hello --substituters 'http://localhost:8080 https://cache.nixos.org' -j0 warning: error: unable to download 'http://localhost:8080/nix-cache-info': HTTP error 500 (Internal Server Error) response body: ; retrying in 530 ms (attempt 1/5) warning: error: unable to download 'http://localhost:8080/nix-cache-info': HTTP error 500 (Internal Server Error) response body: ; retrying in 1051 ms (attempt 2/5) warning: error: unable to download 'http://localhost:8080/nix-cache-info': HTTP error 500 (Internal Server Error) response body: ; retrying in 1974 ms (attempt 3/5) warning: error: unable to download 'http://localhost:8080/nix-cache-info': HTTP error 500 (Internal Server Error) response body: ; retrying in 4054 ms (attempt 4/5) warning: Failed to setup the substituter at URI 'http://localhost:8080': error: unable to download 'http://localhost:8080/nix-cache-info': HTTP error 500 (Internal Server Error) response body: Hello, world! ``` extending reproducer slightly to produce a cache with valid metadata by having ```sh # srv.sh read line echo "$line" >&2 if [[ "$line" = *nix-cache-info* ]]; then echo -en 'HTTP/1.1 200\r\nConnection: close\r\n\r\nStoreDir: /nix/store\n' else echo -en 'HTTP/1.1 500 Internal Server Error\r\nConnection: close\r\n\r\n' fi | tee /dev/stderr # server socat tcp-listen:8080,fork system:'bash srv.sh' # test command nix run --store /tmp/store nixpkgs#hello --substituters 'http://localhost:8080 https://cache.nixos.org' -j0 ``` does not cause a failure, but a long list of retries (too long, we do consider that a bug): ``` warning: error: unable to download 'http://localhost:8080/mi08jhbcjib1i1kgvbd0fxn2yrnzdv4a.narinfo': HTTP error 500 (Internal Server Error) response body: ; retrying in 546 ms (attempt 1/5) warning: error: unable to download 'http://localhost:8080/mi08jhbcjib1i1kgvbd0fxn2yrnzdv4a.narinfo': HTTP error 500 (Internal Server Error) response body: ; retrying in 921 ms (attempt 2/5) warning: error: unable to download 'http://localhost:8080/mi08jhbcjib1i1kgvbd0fxn2yrnzdv4a.narinfo': HTTP error 500 (Internal Server Error) response body: ; retrying in 1893 ms (attempt 3/5) warning: error: unable to download 'http://localhost:8080/mi08jhbcjib1i1kgvbd0fxn2yrnzdv4a.narinfo': HTTP error 500 (Internal Server Error) response body: ; retrying in 3984 ms (attempt 4/5) warning: unable to download 'http://localhost:8080/mi08jhbcjib1i1kgvbd0fxn2yrnzdv4a.narinfo': HTTP error 500 (Internal Server Error) response body: warning: error: unable to download 'http://localhost:8080/mi08jhbcjib1i1kgvbd0fxn2yrnzdv4a.narinfo': HTTP error 500 (Internal Server Error) response body: ; retrying in 376 ms (attempt 1/5) warning: error: unable to download 'http://localhost:8080/mi08jhbcjib1i1kgvbd0fxn2yrnzdv4a.narinfo': HTTP error 500 (Internal Server Error) response body: ; retrying in 983 ms (attempt 2/5) warning: error: unable to download 'http://localhost:8080/mi08jhbcjib1i1kgvbd0fxn2yrnzdv4a.narinfo': HTTP error 500 (Internal Server Error) response body: ... repeated a lot for more retries and narinfos ... ; retrying in 3922 ms (attempt 4/5) warning: unable to download 'http://localhost:8080/pkphs076yz5ajnqczzj0588n6miph269.narinfo': HTTP error 500 (Internal Server Error) response body: Hello, world! ``` so we'd consider your problem fixed, but we probably should not be retrying the same substituter quite this often if it's failing
