cachix cache for attic about attic

[stratosgear]

Sorry for the additional noise, here, but I also do not seem to benefit from using the above binary cache. I really look forward to be able to NOT compile attic that often... :)

That's a good idea, but in this case more dogfooding would be nice. Currently the CI pushes to https://staging.attic.rs/attic-ci (public key: attic-ci:U5Sey4mUxwBXM3iFapmP0/ogODXywKLRNgRPQpEXxbo=) but I'll shortly switch to a more permanent instance that I've been using myself.

Would it be useful to add this cache's config in the flake itself? e.g.

https://github.com/cachix/devenv/blob/5c0f94be41dd900ef473bcda7719e2995e7a9539/flake.nix#L4-L8

I'm not actually sure it propagates to downstream flakes, but if someone were to build this flake directly they could easily benefit from these caches.

I actually prefer this over adding yet another global entry for Cachix, as that increases lookup time for other builds.

It's weird, if I run:

nix run github:zhaofengli/attic \
  --substituters "https://cache.nixos.org" \
  --trusted-public-keys "cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=" \
  --substituters "https://staging.attic.rs/attic-ci" \
  --trusted-public-keys "attic-ci:U5Sey4mUxwBXM3iFapmP0/ogODXywKLRNgRPQpEXxbo="

I see a bunch of stuff downloading from staging.attic.rs, but it still needs to build attic. It's like only the rust deps are cached.

EDIT:

maybe the right command is this, but it still fetches a lot of cargo stuff:

nix run github:zhaofengli/attic \
  --substituters "https://cache.nixos.org https://staging.attic.rs/attic-ci" \
  --trusted-public-keys "cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= attic-ci:U5Sey4mUxwBXM3iFapmP0/ogODXywKLRNgRPQpEXxbo="

Any updates on this? I'm eager to try out attic, but the build takes for ever on my not-too-powerful test server.

[bbigras]

Any progress? It still seems to build everything when I run:

nix run github:zhaofengli/attic \
  --extra-substituters "https://staging.attic.rs/attic-ci" \
  --extra-trusted-public-keys "attic-ci:U5Sey4mUxwBXM3iFapmP0/ogODXywKLRNgRPQpEXxbo="

Did you move from https://staging.attic.rs/attic-ci yet?
