# 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.
