John Ericson	a03b1fd7f6	Deduplicate the Store downcasting with a template	2022-03-11 13:32:33 +00:00
John Ericson	678d1c2aa0	Factor out a LogStore interface ... Continue progress on #5729. Just as I hoped, this uncovered an issue: the daemon protocol is missing a way to query build logs. This doesn't effect `unix://`, but does effect `ssh://`. A FIXME is left for this, so we come back to it later.	2022-03-11 13:32:16 +00:00
Eelco Dolstra	3876238546	Add Installable::toDrvPaths() ... This is needed to get the path of a derivation that might not exist (e.g. for 'nix store copy-log'). InstallableStorePath::toDerivedPaths() cannot be used for this because it calls readDerivation(), so it fails if the store doesn't have the derivation.	2022-01-18 17:28:18 +01:00
Eelco Dolstra	4dda1f92aa	Add command 'nix store copy-log' ... Fixes #5222.	2022-01-18 14:08:49 +01:00
