Materialize Nix expressions (#2301)
* Remove support for local overrides Local overrides ruin binary caching. * Materialize haskell.nix projects Materialization saves the part of the Nix expression which would be generated every time the project is built. This part tracks the package description and dependencies, so it only changes infrequently. Saving the output of this step (so that we can skip building it) makes the build faster. The drawback of this approach is that we must periodically run with checkMaterialization enabled to detect when the materialization needs to be updated. * Separate test and release workflows * Run release workflow only on push to master * Add nix/rematerialize.sh * Run Test workflow on pull requests only * Add a Stack step to Test workflow
