Eelco Dolstra d367b8e787 Add build mode to compute fixed-output derivation hashes ... For example, $ nix-build --hash -A nix-repl.src will build the fixed-output derivation nix-repl.src (a fetchFromGitHub call), but instead of *verifying* the hash given in the Nix expression, it prints out the resulting hash, and then moves the result to its content-addressed location in the Nix store. E.g build produced path ‘/nix/store/504a4k6zi69dq0yjc0bm12pa65bccxam-nix-repl-8a2f5f0607540ffe56b56d52db544373e1efb980-src’ with sha256 hash ‘0cjablz01i0g9smnavhf86imwx1f9mnh5flax75i615ml71gsr88’ The goal of this is to make all nix-prefetch-* scripts unnecessary: we can just let Nix run the real thing (i.e., the corresponding fetch* derivation). Another example: $ nix-build --hash -E 'with import <nixpkgs> {}; fetchgit { url = "https://github.com/NixOS/nix.git"; sha256 = "ffffffffffffffffffffffffffffffffffffffffffffffffffff"; }' ... git revision is 9e7c1a4bbd ... build produced path ‘/nix/store/gmsnh9i7x4mb7pyd2ns7n3c9l90jfsi1-nix’ with sha256 hash ‘1188xb621diw89n25rifqg9lxnzpz7nj5bfh4i1y3dnis0dmc0zp’ (Having to specify a fake sha256 hash is a bit annoying...)		2016-01-31 12:18:09 +01:00
