# Since this is the only test using "real" external modules fetched via GOPROXY,
# go.mod and go.sum should declare the dependencies.

# For now, use a throwaway module download cache instead of the host machine's.
# Usually it would be fine to reuse the host's, since we expose exact copies of
# some external modules in a local proxy, allowing 'go test' to work offline.
# However, for some reason, we end up with different hashes of the code for
# modules like rsc.io/quote, and it's unclear why. It might be a txtar-addmod bug.
# In any case, not worth our time to investigate right now, and "downloading"
# modules is instant since we just copy a handful of files.
#
# To reproduce the issue, remove the env line and run:
#
#    go clean -modcache && go get -d rsc.io/quote@v1.5.2 && go test -short
env GOMODCACHE=$WORK/modcache
