 emily | (and those won't show up in the totals…) | 17:21:54 |
 samasaur | solely from an end user perspective I would like the update. tried to do an overlay to get it back to 10.0 and either I did it wrong or that's not possible to do on darwin (got an error about a failing assertion about things not being built by the bootstrap compiler) | 17:26:23 |
 aloisw | https://github.com/NixOS/nixpkgs/pull/456258 has openssh_10_2, feel free to comment if you want something else. | 17:34:57 |

 Ihar Hrachyshka | it would be nice to get https://github.com/NixOS/nixpkgs/issues/454709 before next staging -> staging-next (firefox is broken otherwise) | 03:50:25 |

 uep | yeah i hit this too.. but also I just used mosh instead and ssh was fine to get mosh started | 05:47:49 |
 Vladimír Čunát | Huh, trunk-combined now has 25k rebuilds, after three days. | 08:55:53 |
| Vladimír Čunát | We're not going easy on rebuids in master. (and the openssl default update has not been merged (yet)) | 08:56:26 |
| Vladimír Čunát | I guess part of that could be avoided by reverting

| emily | vcunat: sorry about the aliases in NixOS tests thing, will take a look | 16:56:29 |
| Vladimír Čunát | context: https://github.com/NixOS/nixpkgs/pull/456065#issuecomment-3457488163 | 16:56:58 |
| emily | lack of CI coverage for NixOS eval is really sad | 16:58:23 |
| Vladimír Čunát | It's expensive. | 16:59:57 |
| Vladimír Čunát | Takes more than one hour on Hydra. Part of that is a huge postgresql transaction, but the eval costs are really high. | 17:00:31 |
| Vladimír Čunát | I think it's OK that some classes of errors don't get caught by CI but only through Hydra/channels. | 17:02:25 |
| emily | yeah, not saying it's easily solvable | 17:03:34 |
| emily | but it would be really nice if it was solved | 17:03:40 |
| emily | has anyone ever looked at if evaluating all the NixOS tests has some specific hot spot? | 17:04:03 |
| emily | is it instantiating a billion Nixpkgs? just the module system being slow? | 17:04:13 |
 K900 | It is both | 17:04:18 |
| K900 | I tried https://github.com/K900/nixpkgs/tree/less-nixpkgses and somehow in our testing on forkos hydra it made things worse | 17:04:38 |
| Vladimír Čunát | Wolfgang Walther is also looking at it, apparently. | 17:04:39 |
| Vladimír Čunát | Let's see who's faster 😅 | 17:04:52 |
| K900 | Which makes no fucking sense | 17:04:57 |
| emily | Hydra eval is parallelized with nix-eval-jobs, right? | 17:05:51 |
| emily | is anything shared between the evaluations of multiple NixOS tests? | 17:05:58 |
| Vladimír Čunát | I'm more worried about the expenses to run all the tests. | 17:06:29 |
| Vladimír Čunát | Because I can see the huge difference between e.g. trunk and trunk-combined. | 17:06:42 |
