Eelco Dolstra	6644b6099b	Add flake evaluation cache ... This exploits the hermetic nature of flake evaluation to speed up repeated evaluations of a flake output attribute. For example (doing 'nix build' on an already present package): $ time nix build nixpkgs:firefox real 0m1.497s user 0m1.160s sys 0m0.139s $ time nix build nixpkgs:firefox real 0m0.052s user 0m0.038s sys 0m0.007s The cache is ~/.cache/nix/eval-cache-v1.sqlite, which has entries like INSERT INTO Attributes VALUES( X'92a907d4efe933af2a46959b082cdff176aa5bfeb47a98fabd234809a67ab195', 'packages.firefox', 1, '/nix/store/pbalzf8x19hckr8cwdv62rd6g0lqgc38-firefox-67.0.drv /nix/store/g6q0gx0v6xvdnizp8lrcw7c4gdkzana0-firefox-67.0 out'); where the hash 92a9... is a fingerprint over the flake store path and the contents of the lockfile. Because flakes are evaluated in pure mode, this uniquely identifies the evaluation result.	2019-06-07 22:25:48 +02:00
