Eelco Dolstra	a053d2d8e5	* Add the deriver to the ValidPaths table. In principle we could now ... store all the derivers of a path efficiently. But that opens a big can of worms with respect to garbage collector semantics.	2010-02-18 13:48:18 +00:00
Eelco Dolstra	dbddac0fe9	* Assign an integer id to every row in the ValidPaths table in order ... to make the Refs table more space-efficient. For instance, this reduces the size of the database on my laptop from 93 MiB to 18 MiB. (It was 72 MiB with the old schema on an ext3 disk with a 1 KiB block size.)	2010-02-18 13:40:46 +00:00
Eelco Dolstra	c1a07f9445	* Convert the Nix database to SQLite.	2010-02-18 13:16:59 +00:00
