2011-08-17	* Use last_insert_id instead of sqlite_last_insert_rowid, which you're	Eelco Dolstra
	not really supposed to use according to the DBD::SQLite docs, and fails on some systems (e.g. http://hydra.nixos.org/build/1246662).
2011-07-13	* Fix concurrency issues in download-using-manifests' handling of the	Eelco Dolstra
	SQLite manifest cache. The DBI AutoCommit feature caused every process to have an active transaction at all times, which could indefinitely block processes wanting to update the manifest cache. * Disable fsync() in the manifest cache because we don't need integrity (the cache can always be recreated if it gets corrupted).
2011-04-11	* Read manifests directly into the database, rather than first reading	Eelco Dolstra
	them into memory. This brings memory use down to (more or less) O(1). For instance, on my test case, the maximum resident size of download-using-manifests while filling the DB went from 142 MiB to 11 MiB.
2011-04-11	* Lock the database during updates.	Eelco Dolstra

2011-04-11	* Create $manifestDir if it doesn't exist.	Eelco Dolstra

2011-04-10	* Cache the manifests in /nix/var/nix/manifests in a SQLite database.	Eelco Dolstra
	This significantly speeds up the download-using-manifests substituter, especially if manifests are very large. For instance, one "nix-build -A geeqie" operation that updated four packages using binary patches went from 18.5s to 1.6s. It also significantly reduces memory use. The cache is kept in /nix/var/nix/manifests/cache.sqlite. It's updated automatically when manifests are added to or removed from /nix/var/nix/manifests. It might be interesting to have nix-pull store manifests directly in the DB, rather than storing them as separate flat files, but then we would need a command line interface to delete manifests from the DB.
2011-04-06	* Remove the localPaths feature in manifests since it's no longer used	Eelco Dolstra
	and redundant anyway.
2010-12-05	* Use CamelCase for the Perl modules.	Eelco Dolstra
