## Summary This PR is an alternative approach to #949 which should be much safer. As in #949, we add a `Refresh` policy to the cache. However, instead of deleting entries from the cache the first time we read them, we now check if the entry is sufficiently new (created after the start of the command) if the refresh policy applies. If the entry is stale, then we avoid reading it and continue onward, relying on the cache to appropriately overwrite based on "new" data. (This relies on the preceding PRs, which ensure the cache is append-only, and ensure that we can atomically overwrite.) Unfortunately, there are just a lot of paths through the cache, and didn't data is handled with different policies, so I really had to go through and consider the "right" behavior for each case. For example, the HTTP requests can use `max-age=0, must-revalidate`. But for the routes that are based on filesystem modification, we need to do something slightly different. Closes #945. |
