 Amine Chikhaoui | restarted queue-runner also, let's see if it makes any difference | 15:18:43 |
 @grahamc:nixos.org | I think some more mac capacity should be coming up too | 15:35:44 |
 Sandro | I think we already have consensus that if we want better Mac support that ofborg needs machines. IIRC we also already have machines they just need to be set up and people that have time for that don't have permissions and the people that have permissions don't have time. | 18:09:26 |
 toonn | Are there more machines actually? grahamc you mentioned a couple weeks ago that there were a couple macstadium machines and another box available but I think you've already added those to Hydra? | 18:18:47 |
| Sandro | I was referring to the macstadium ones. Maybe they where for hydra. I am a bit out of the loop | 18:21:24 |
| toonn | There's three x86_64-darwin builders on this page with hashes for names, https://hydra.nixos.org/machines I assumed these were the new additions. | 18:23:31 |

 Jonas Chevalier | discourse.nixos.org migration in progress... | 15:38:14 |
|  Alexander Vershilov joined the room. | 15:44:56 |
| Alexander Vershilov | On a local laptop I have random haskell packages build hang with ghc-8.10.{3,4}, but I'm not sure how to debug that. If there any tips I can try them in case it may help investigation | 15:51:23 |
 sterni | may want to update your nixpkgs, we haven't had GHC 8.10.4 for quite some time now | 15:52:33 |
 rnhmjoj | something funny's going on with the nixos-discourse bot: i received a notification from something mentioned in 2019 | 18:39:58 |
| rnhmjoj | (also notice the wrong domain in the linked post) | 18:40:33 |
 Domen Kožar | yeah, all the emails are being resent | 19:19:09 |

Evaluation running since: 1h ago
I wonder where are boundaries of what we "can afford", though this attempt seems to be significantly worse than most in trunk-combined.

 Janne Heß | Wasn't there a nix PR by eelco that speeds up primops? Maybe that helps a bit | 10:47:46 |

is this a legit eval or did some ifd get introduced by accident? | 11:33:44 |
| Jonas Chevalier | IFDs are not allowed by the hydra evaluator | 11:54:09 |
 moritz.hedtke | Maybe a bug? Or extreme overload and the GC is running all the time? What is the expected time? | 11:54:48 |
| Jonas Chevalier | An easy way to find out is to execute the evaluation yourself, and bisect to the change that caused the time to increase | 11:56:06 |
| Jonas Chevalier | (assuming you have 64G? of RAM available) | 11:56:26 |
| Jonas Chevalier | Often it's a combinatorial issue, like evaluating all of nixpkgs a second time, with a different variant of the stdlib. | 11:57:02 |
 hexa | I remember something around 18 minutes for staging-next, if I'm not mistaken | 14:35:20 |
| Vladimír Čunát | non-NixOS evals are normally way cheaper than the -combined ones. | 16:18:25 |
