 dramforever | * ideas on whether https://github.com/NixOS/nix/pull/15572 should be backported and if so to what versions? it fixes a nix-functional-tests "failure" on linux 6.19+ | 08:27:51 |
 Sergei Zimmerman (xokdvium) | Sure. You should be able to add backport tags | 09:06:27 |
| Sergei Zimmerman (xokdvium) | (Nixpkgs committers do have triage perms iirc) | 09:06:46 |
| Sergei Zimmerman (xokdvium) | As for the versions, probably everything that is in nixpkgs | 09:07:16 |
| Sergei Zimmerman (xokdvium) | * Sure. You should be able to add backport labels | 09:16:36 |

 Arian | I was wondering. Would a mode where nix evaluator stays alive across invocations make sense? Similar what Buck2 does ? | 17:49:37 |
 Jeremy Fleischman (jfly) | Morgan (@numinit) built this madness: https://github.com/numinit/flack | 17:53:30 |
| Jeremy Fleischman (jfly) | seems like it should be a way to trade off RAM for more eval caching | 17:54:38 |
| Arian | In general would be interested to steal things from buck | 18:17:17 |
| Arian | They integrate with watchman to invalidate evaluation on file changes | 18:17:28 |
| Arian | Actually they use it for not just eval and also build... But just for eval is already interestinh | 18:17:52 |

 eveeifyeve | Eelco: It's really interesting looking through the movement on NaN canonicalization wasm issue, I am not too exactly some user choose to make it required and some don't. It might be a good to get some idea from the wasm developers (if it's not required, The question is what is it's use.). | 13:14:56 |

 Vladimír Čunát | I noticed when looking around Hydra that now tests.nix-copy very often fails, even on multiple older Nix branches, e.g. https://hydra.nixos.org/build/325164327#tabs-buildsteps | 07:04:53 |

| Sergei Zimmerman (xokdvium) | I’ve seen a lot of nixosTests timing out because backdoor service doesn’t spin up or something along those lines. It seems like something borked with vm tests machinery | 08:15:32 |
| Sergei Zimmerman (xokdvium) | In nix-copy specifically I think we just lack some synchronisation between server/client | 08:18:18 |
