Eelco Dolstra ccc52adfb2 Add function queryPathFromHashPart() ... To implement binary caches efficiently, Hydra needs to be able to map the hash part of a store path (e.g. "gbg...zr7") to the full store path (e.g. "/nix/store/gbg...kzr7-subversion-1.7.5"). (The binary cache mechanism uses hash parts as a key for looking up store paths to ensure privacy.) However, doing a search in the Nix store for /nix/store/<hash>* is expensive since it requires reading the entire directory. queryPathFromHashPart() prevents this by doing a cheap database lookup.		2012-07-17 18:55:39 -04:00
