 Vladimír Čunát | Huh, I didn't realize that the Hydra's queue runner is dumb enough to attempt building exactly the same derivation twice in parallel. Right now:
https://hydra.nixos.org/build/298195286
https://hydra.nixos.org/build/298186259
(note the timestamps etc.) The only luck here is that they got scheduled to the same builder machine and Nix on the machine does deduplicate that. | 08:08:20 |
| Vladimír Čunát | That might be happening a lot now, as 25.05 does not differ much from unstable/master yet - and quite commonly nixpkgs:trunk has significant job overlap nixos:trunk-combined. | 08:11:23 |

| Vladimír Čunát | Here a darwin case where it scheduled to different machines and really duplicates:

 Alyssa Ross | What's the current Hydra output size limit? | 17:16:25 |
 hexa | max_output_size = 4121225472 # 3 << 30 + 900000000 = 3 GiB + 0.9 GB
| 17:17:05 |
| hexa | from nixos/infra in build/hydra.nix | 17:17:11 |
| Alyssa Ross | wonderful | 17:17:22 |
