cachix-action-v5

v4 had a regression of not building anything in PRs

cachix-action-v4

• Add nixBuildArgs parameter

• Simplify how paths are pushed

  Previously we were setting up Nix build hook to make sure all paths are
  synced to cachix.

  This had a few flaws:

  • nix-daemon had to be restarted, resulting into a few seconds extra
    setup per each build
  • spurious error on macos due to nix-daemon socket not ready in time
  • significant overhead since syncing to cachix was synchronous for each
    derivation built

  Now we just look for new store paths and push those after nix-build.

cachix-action-v3

• add skipNixBuild option. By default false. If true, caches will only be configured for pulling, avoiding pushing and nix-build
• upload all build-time (not only run-time) dependencies to Cachix via post-build-hook
• use official Cachix installation URL

cachix-action-v2

• fix cachix: CppStdException "Exception: path '/nix/store/... ' is not valid; type: nix::InvalidPath"

• don't error out if signing key is missing (typical on pull requests)
