Partially reverts #32686.
PR caches inherit from caches generated in
main
. If it cannot find that cache, it will create one scoped to just that PR (and PRs that inherit from it).There is an edge case where cache eviction can happen in the middle of a test run. If cache eviction removes a
main
cache, child jobs that depend on it will start failing because of thefail-on-cache-miss
setting.This PR reverts the default behavior. If this happens, the workflow will still continue in slow mode where it will
yarn install
child jobs instead of reusing from cache. This is slower but will at least allow workflows to continue.Additionally I added restore keys so that we can fallback to other caches if present so
yarn install
doesn't need to start over from scratch.
