builtins.baseNameOf
andbuiltins.pathExists
requires the derivation that providespath
in its output to be built during evaluation phase. We have ax86_64-linux
Hydra server with a MacOS machine as a remote builder. We evaluate all derivations on the main Hydra server, only distributing the actual building to MacOS.builtins.pathExists
caused the entire build process of MacOS derivations to run during evaluation. Those heavy work won't show as normal Hydra jobs, and the failures are shown in "Evaluation Error" tab.
