Andrew Gallant 5b8ed92f95 uv-client: switch heuristic freshness lifetime to hard-coded value ... The comment in the code explains the bulk of this: ```rust // We previously computed this heuristic freshness lifetime by // looking at the difference between the last modified header and // the response's date header. We then asserted that the cached // response ought to be "fresh" for 10% of that interval. // // It turns out that this can result in very long freshness // lifetimes[1] that lead to uv caching too aggressively. // // Since PyPI sets a max-age of 600 seconds and since we're // principally just interacting with Python package indices here, // we just assume a freshness lifetime equal to what PyPI has. // // Note though that a better solution here is for the index to // support proper HTTP caching headers (ideally Cache-Control, but // Expires also works too, as above). ``` We also remove the `heuristic_percent` field on `CacheConfig`. Since that's actually part of the cache itself, we bump the simple cache version. Finally, we add some more `trace!` calls that should hopefully make diagnosing issues related to the freshness lifetime a bit easier in the future. Fixes #5351		2024-07-31 08:12:11 -07:00
