From eeda228c2d1719f5b6276b40ad14a5b3c3e88536 Mon Sep 17 00:00:00 2001 From: Eric Garver Date: Wed, 22 May 2019 21:44:04 +0200 Subject: src: update cache if cmd is more specific If we've done a partial fetch of the cache and the genid is the same the cache update will be skipped without fetching the needed items. This change flushes the cache if the new request is more specific than the current cache - forcing a cache update which includes the needed items. Introduces a simple scoring system which reflects how cache_init_objects() looks at the current command to decide if it is finished already or not. Then use that in cache_needs_more(): If current command's score is higher than old command's, cache needs an update.
