From 6454769eefc6be2bc3f7351f915ca0be37e07541 Mon Sep 17 00:00:00 2001 From: Florian Klink Date: Thu, 30 Mar 2023 13:31:52 +0200 Subject: refactor(tvix/nix-compat): drop is_derivation in build_store_path This only added a suffix to the input argument, if build_store_path was building the path of a Derivation. As we need to also add the `.drv` suffix to the name we pass into text_hash_string inside calculate_derivation_path, we can simply add the suffix there and drop the parameter from build_store_path.
