From f83e82cd00653b443b180ad100886bd096209b83 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Tue, 12 Jan 2016 14:54:39 +0100 Subject: daemon: check: Fix assertion failure when some outputs are missing. E.g. $ nix-build pkgs/stdenv/linux/ -A stage1.pkgs.perl --check nix-store: src/libstore/build.cc:1323: void nix::DerivationGoal::tryToBuild(): Assertion `buildMode != bmCheck || validPaths.size() == drv->outputs.size()' failed. when perl.out exists but perl.man doesn't. The fix is to only check the outputs that exist. Note that "nix-build -A stage1.pkgs.all --check" will still give a (proper) error in this case. --- nix/libstore/build.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'nix/libstore/build.cc') diff --git a/nix/libstore/build.cc b/nix/libstore/build.cc index 2f8b4dabba..07babf9797 100644 --- a/nix/libstore/build.cc +++ b/nix/libstore/build.cc @@ -1291,7 +1291,6 @@ void DerivationGoal::tryToBuild() now hold the locks on the output paths, no other process can build this derivation, so no further checks are necessary. */ validPaths = checkPathValidity(true, buildMode == bmRepair); - assert(buildMode != bmCheck || validPaths.size() == drv.outputs.size()); if (buildMode != bmCheck && validPaths.size() == drv.outputs.size()) { debug(format("skipping build of derivation `%1%', someone beat us to it") % drvPath); outputLocks.setDeletion(true); @@ -2430,6 +2429,7 @@ void DerivationGoal::registerOutputs() PathSet references = scanForReferences(actualPath, allPaths, hash); if (buildMode == bmCheck) { + if (!store->isValidPath(path)) continue; ValidPathInfo info = worker.store.queryPathInfo(path); if (hash.first != info.hash) throw Error(format("derivation `%1%' may not be deterministic: hash mismatch in output `%2%'") % drvPath % path); -- cgit v1.2.3
