Currently yubihsm's Mock HSM cannot be used with release builds which means we cannot use it in our integration tests. Upstream should be notified of that use-case and ideally allow building MockHSM even in non-debug builds. The following discussion from !338 should be addressed: - [ ] @dvzrv started a [discussion](https://gitlab.archlinux.org/archlinux/signstar/-/merge_requests/338#note_396276): > ```suggestion:-8+0 > case "$project" in > nethsm-cli) > printf "Installing executables of signstar-request-signature\n" > cargo install --locked --path signstar-request-signature > printf "Installing executables of %s...\n" "{{ project }}" > cargo install --locked --all-features --path {{ project }} > ;; > signstar-yubihsm2) > # we need --debug because of mockhsm of signstar-yubihsm which fails to compile > # in release builds :( > printf "Installing debug executables of %s...\n" "{{ project }}" > cargo install --locked --debug --all-features --path {{ project }} > ;; > *) > printf "Installing executables of %s...\n" "{{ project }}" > cargo install --locked --all-features --path {{ project }} > ;; > esac > ``` > > This way we only use debug builds for the `signstar-yubihsm2` README and don't slow down the other README tests. > > But also, we should contact the yubihsm.rs upstream about this... :smiling_face_with_tear:
