Eelco Dolstra	e0204f8d46	Move path info caching from BinaryCacheStore to Store ... Caching path info is generally useful. For instance, it speeds up "nix path-info -rS /run/current-system" (i.e. showing the closure sizes of all paths in the closure of the current system) from 5.6s to 0.15s. This also eliminates some APIs like Store::queryDeriver() and Store::queryReferences().	2016-04-19 18:52:53 +02:00
