From 84722d67d2b09b5c28e1c2d9dd438ba592df2296 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Sat, 3 Feb 2018 10:04:29 +0100 Subject: Remove nix-build --hash Instead, if a fixed-output derivation produces has an incorrect output hash, we now unconditionally move the outputs to the path corresponding with the actual hash and register it as valid. Thus, after correcting the hash in the Nix expression (e.g. in a fetchurl call), the fixed-output derivation doesn't have to be built again. It would still be good to have a command for reporting the actual hash of a fixed-output derivation (instead of throwing an error), but "nix-build --hash" didn't do that. --- tests/fixed.sh | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) (limited to 'tests/fixed.sh') diff --git a/tests/fixed.sh b/tests/fixed.sh index cac3f0be91b0..8f51403a7071 100644 --- a/tests/fixed.sh +++ b/tests/fixed.sh @@ -5,15 +5,22 @@ clearStore export IMPURE_VAR1=foo export IMPURE_VAR2=bar +path=$(nix-store -q $(nix-instantiate fixed.nix -A good.0)) + +echo 'testing bad...' +nix-build fixed.nix -A bad --no-out-link && fail "should fail" + +# Building with the bad hash should produce the "good" output path as +# a side-effect. +[[ -e $path ]] +nix path-info --json $path | grep fixed:md5:2qk15sxzzjlnpjk9brn7j8ppcd + echo 'testing good...' nix-build fixed.nix -A good --no-out-link echo 'testing good2...' nix-build fixed.nix -A good2 --no-out-link -echo 'testing bad...' -nix-build fixed.nix -A bad --no-out-link && fail "should fail" - echo 'testing reallyBad...' nix-instantiate fixed.nix -A reallyBad && fail "should fail" -- cgit 1.4.1
