 K900 | OK great it's in staging-next now because 4.13 doesn't build anymore | 15:41:13 |
| K900 | And I am taking back everything bad I said about the Python ecosystem today | 15:41:29 |

OK great it's in staging-next now because 4.13 doesn't build anymore did you check to see if all FOD hashes have to be recalculated or not | 17:12:35 |
| K900 | My small-ish sample says not all | 17:12:51 |
| K900 | But some things needed lockfile patches and got recalculated on the PR | 17:13:03 |
| dish [Fox/It/She] | i figured it wouldn't be all, but i heard of a decent number of breakages on the original update pr | 17:13:14 |
| dish [Fox/It/She] | which is why it got reverted | 17:13:21 |
| K900 | Well the author of the other PR claimed to have fixed them all | 17:13:34 |
| dish [Fox/It/She] | then we should be fine | 17:15:14 |
| 10 May 2026 |
| K900 | Well my everything rebuild is done and nothing significant exploded | 04:37:42 |
| K900 | So that's nice | 04:37:45 |

seems to fix it, probably because rustversion::before from upstream bytemuck is always there on stable. | 20:20:43 |

 vcunat | There's a musl blocker:

Alyssa Ross I guess? | 09:22:00 |
|  teutat3s joined the room. | 09:33:49 |
 Alyssa Ross | Builds locally for me. | 12:33:53 |
| hexa | restarted | 12:34:43 |
| hexa | or rather I clicked and it keeps loading 🤔 | 12:35:56 |
| vcunat | Most likely because eval is in late stage, so a huge postgresql transaction hogs everything involved. | 12:37:12 |
| hexa | that tracks | 12:37:46 |
| K900 | Did we merge a big rebuild into next | 13:28:07 |
| vcunat | groff: https://github.com/NixOS/nixpkgs/pull/517946#issuecomment-4420481095 | 13:35:17 |
| vcunat | On Hydra it looked like wasting around 7k jobs. (but part of that might've been due to other changes) Not that bad, considering that it's *-linux jobs. | 13:37:11 |
| K900 | Ouch | 13:38:14 |
| K900 | Welp | 13:38:15 |
