# This test is regarding https://github.com/NixOS/hydra/pull/1126
#
# A hydra instance was regularly failing to build derivations with:
#
# possibly transient failure building /nix/store/X.drv on localhost:
# dependency '/nix/store/Y' of '/nix/store/Y.drv' does not exist,
# and substitution is disabled
#
# However it would only fail when building on localhost, and it would only
# fail if the build output was already in the binary cache.
#
# This test replicates this scenario by having two jobs, underlyingJob and
# dependentJob. dependentJob depends on underlyingJob. We first build
# underlyingJob and copy it to an external cache. Then forcefully delete
# the output of underlyingJob, and build dependentJob. In order to pass
# it must either rebuild underlyingJob or fetch it from the cache.
