| # Restore the most appropriate caches. | |

| # In the below: `github.ref` will be either "refs/pull/<pr_number>/merge" | |
| # or "refs/heads/main"; `github.run_number` is a monotonically increasing | |
| # serial number; and `github.run_attempt` is a typically 1. | |
| # | |
| # The `key` declared here will never match (since it encodes the current | |
| # run_number) but illustrates the name we'll use to save the caches when | |
| # we're done. | |
| # | |
| # However, one of the `restore-keys` patterns *should* always match. The | |
| # effects we should see from the `restore-keys` patterns are: | |
| # | |
| # * When building the `main` branch, we'll always pull the most recently | |
| # updated main caches. Both restore keys say "pip-refs/heads/main-" and | |
| # the prior archives are named, e.g., "pip-refs/heads/main-####-#". | |
| # GitHub will use the *most recently saved* archive name that matches | |
| # the restore key prefix (no matter the lexicographic ordering of | |
| # the ####-# part). | |
| # | |
| # * Ditto for the first build of a PR; the first restore key will not | |
| # match anything, so it falls back to the main caches. | |
| # | |
| # * For subsequent builds of a PR, the first restore key, e.g., | |
| # "pip-refs/pull/###/merge-" should match the most recently saved PR key | |
| # "pip-refs/pull/###/merge-####-#". | |
