Until now, it was not possible to substitute missing paths from e.g. `https://cache.nixos.org` on a remote server when building on it using the new `ssh-ng` protocol. This is because every store implementation except legacy `ssh://` ignores the substitution flag passed to `Store::queryValidPaths` while the `legacy-ssh-store` substitutes the remote store using `cmdQueryValidPaths` when the remote store is opened with `nix-store --serve`. This patch slightly modifies the daemon protocol to allow passing an integer value suggesting whether to substitute missing paths during `wopQueryValidPaths`. To implement this on the daemon-side, the substitution logic from `nix-store --serve` has been moved into a protected method named `Store::substitutePaths` which gets currently called from `LocalStore::queryValidPaths` and `Store::queryValidPaths` if `maybeSubstitute` is `true`. Fixes #2770 |
