cache checks #83
Description
Hello,
is it possible to cache checks? I am attempting to move from using my own s3 cache to this to simplify a bit the setup but I am having an issue because the result of running the checks doesn't seem to be cached. Because some of my tests requires a bit of infrastructure I was doing something like the following:
- name: "Verify if we need to build"
id: verify-build
run: |
export check_dry_run_output=$(nix build \
--dry-run \
--json \
--print-build-logs \
.\#checks.$(ARCH)-$(OS).$(NAME))
export drvPath=$(echo "$check_dry_run_output" | grep -oE '"out":.*"' | awk -F\" '{ print $4 }')
nix store verify --no-trust --store s3://..... $drvPath \
&& export BUILD_NEEDED=no \
|| export BUILD_NEEDED=yes
echo BUILD_NEEDED=$BUILD_NEEDED >> $GITHUB_OUTPUTThen in the rest of the workflow I can just use BUILD_NEEDED to skip unnecessary tests.
However, this doesn't seem to work after moving to use this store instead of s3, I suspect because the check derivation isn't being cached.
