 raboof | things like https://cache.nixos.org/5yzw0vhkyszf2d179m0qfkgxmp5wjjx4.narinfo have no deriver but are in the cache anyway... do those ever get fetched? wouldn't they always be present locally because they're created as part of instantiation? | 15:26:14 |
 dramforever | you don't have to eval to download stuff from cache.nixos.org, there's nix copy | 15:27:54 |
| dramforever | uh, with --substitute-on-destination | 15:28:16 |
| dramforever | or you can nix copy --from https://cache.nixos.org a path | 15:28:31 |
| dramforever | but the point is no, it won't always be present locally | 15:28:55 |
| raboof | right, you can, but I wondered if/when that happens in practice | 15:30:58 |
| dramforever | --substitute-on-destination definitely happens in practice | 15:32:11 |
 fzakaria | anyone want to pair/hack tonight? | 20:11:25 |
| fzakaria | Question I was confused by Jeremy Fleischman (jfly) :
When calculating store-paths, Nix does "Hashing modulo fixed-output derivations" -- this makes sense since you want the store-path to be stable for multiple drvs for the FOD.
His question:
Can we replace all the inputDrvs with their store-path and also achieve the same thing?
(replace via the same massaging that we do for FODs)
