CI: Reduce Actions cache pressure in ResInsightWithCache - #14586
Merged
Conversation
Only save the buildcache from the default branch. GitHub scopes cache writes to the current ref, so a cache saved from a feature branch or PR is invisible to every other branch while still counting against the 10 GB per-repository quota and evicting the shared caches on the default branch. Disable unity build for all configurations. Unity blobs invalidate on any change to the sources they bundle, which defeats buildcache reuse and fills the cache with objects that are unlikely to be hit again.

Two changes to
ResInsightWithCache.ymlaimed at the GitHub Actions cache quota for the repository.Only save the buildcache from the default branch. GitHub scopes cache writes to the current ref, and a branch can read only its own scope plus the default branch. A cache saved from a feature branch or PR is therefore invisible to every other branch, yet it still counts against the 10 GB per-repository quota and evicts the shared caches on the default branch.
Disable unity build for all configurations. Unity blobs invalidate whenever any of the sources they bundle change, which defeats buildcache reuse and fills the cache with objects unlikely to be hit again. This matches
ResInsightMac.yml,rhel8-package.ymlandrhel8-unit-tests.yml, which already build with unity off.The
restore-keysprefix fallback is left as is, so branches keep restoring the most recent cache for their configuration. The nightly scheduled run on the default branch remains the producer of the shared caches.
