 Sergei Zimmerman (xokdvium) | Eelco: debugged the i686-linux failures in hydra. Turns out we had a buggy unsigned promotion this whole time if time_t is 32 bit (which it apparently still is on i686?)

 jaen | Playing around with dynamic derivations and the following:
builtins.outputOf (builtins.outputOf plannerDrv.outPath "out") "out"
nets me an error like this:
error: error parsing derivation '/nix/store/…-group-0': store path '…-group-0' is not a valid derivation path
This an attempt at multi-level CA-guarded rebuild chunking — the planner creates the build graph (in this case, from ninja files), the intermediate builder (or builders depending on what makes more sense there can be > 1 level of chunks) that eventually emits a directory with build outputs. And I'm not entirely sure if it's me who is doing something wrong and this is intended not to work, or whether this is some implementation oversight and/or current limitation?

| jaen | Now that I think about it, it's probably what https://github.com/NixOS/nix/issues/12727 is talking about, in which case I'm wondering how hard would it be to fix? I seem to have hacked this out by just checking if this parses as a derivation or not to decide whether we arrived at the leaf, but looking at the issue I assume that's not probably a principled enough solution? | 18:31:16 |
