 Leonardo Santiago | what is the reasoning behind calling nix_value_force before returning the Value? I find this not only confusing but detrimental as it evaluates a lot more than needed most of the time. | 14:03:58 |
| Leonardo Santiago | I'm saying this because a builtins.getFlake "path" call is taking 20 seconds (even though it's local, not copying anything) and I can't trace it to anything other than it evaluating the packages outputs even though I'm not asking for it | 14:26:17 |
| Leonardo Santiago | I'm trying to setup a minimal example | 14:26:43 |
| Leonardo Santiago | yes, I can see it's evaluating outputs.packages.x86_64-linux.default by adding a builtins.trace to it, though it seems to be the only one being eagerly evaluated | 14:39:29 |
| Leonardo Santiago | forget about it, I was testing out flake-compat and in the end it adds
defaultNix =
(builtins.removeAttrs result ["__functor"])
// (if result ? defaultPackage.${system} then { default = result.defaultPackage.${system}; } else {})
// (if result ? packages.${system}.default then { default = result.packages.${system}.default; } else {});
and it was this result ? defaultPackage.${system} that was causing the attribute to be evaluated when importing. when using builtins.getFlake, this doesn't happen but the slowness comes from copying the whole directory to the store

I was thinking of making a libflake subclass of the evaluator subclassing feels like a step back | 11:17:03 |

| Robert Hensing (roberth) | I've added libflake to bring back getFlake. Call these three functions before creating an eval state: https://github.com/NixOS/nix/pull/11940/files#diff-5bf91a38f0c7fb288abe818751d512cdb01277aced08211b0b888fc73d67f103 | 16:54:13 |
