 Jens Petersen | I am curious, will nixos/nixpkgs 26.05 ship nix-2.32? (asking since I am thinking to update fedora nix - obviously that's a rather smaller deal) | 03:29:02 |
|  dre joined the room. | 05:40:54 |
 Sergei Zimmerman (xokdvium) | Depends on how 2.34 goes I suppose. There's still > 1 month for merge window in nixpkgs and hopefully that can become the next stable | 11:12:11 |
| Jens Petersen | Ah okay so you will jump to 2.34? cool | 11:12:52 |
| Jens Petersen | Anyway I built 2.32 for Fedora Rawhide today finally | 11:13:45 |
| Sergei Zimmerman (xokdvium) | Hm this reminds me that I should cut a point release for 2.32 with a bugfix for https://github.com/NixOS/nix/pull/15087 | 11:14:21 |
| Jens Petersen | aha :) | 11:14:36 |
| Sergei Zimmerman (xokdvium) | Would be nice to catch that for fedora bump I think | 11:15:47 |

| 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?)

| Sergei Zimmerman (xokdvium) | I recall there was a push to switch to 64 bit everywhere but I can't find the nixpkgs issue now | 20:59:41 |

 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?
| 18:31:13 |
| 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 |
| Sergei Zimmerman (xokdvium) | 2.32 bump in 25.11 https://github.com/NixOS/nixpkgs/pull/494829 | 22:36:42 |
| Sergei Zimmerman (xokdvium) | Jens Petersen: Artemis Tosini (NixOS) and John Ericson have put significant effort into getting multiuser installs working working without requiring root for 2.34. It works by running the daemon in an unprivilidged userns with subuid/subgid mappings for build users. Would that be something that fedora packaging would be interested in? | 22:43:49 |
| Sergei Zimmerman (xokdvium) | Might still be rough around the edges, but our test suite passes with that setup in nixos tests https://github.com/NixOS/nix/blob/master/tests/nixos/functional/unprivileged-daemon.nix | 22:48:19 |
