 Yureka (she/her) | so it is odd that the FOD hashes change | 08:56:43 |
 K900 | Yarn 4.14 seems to require lockfile changes for some packages | 08:56:50 |
| Yureka (she/her) | Ah | 08:56:55 |
| Yureka (she/her) | If the lockfile changes, the FOD hash changes | 08:56:59 |
| K900 | Yeah | 08:57:03 |
| Yureka (she/her) | because the lockfile is copied to the FOD | 08:57:06 |
| K900 | But it's some and not all | 08:57:10 |
| K900 | It's weird | 08:57:12 |
| Yureka (she/her) | but this does not require any change on the fetchYarnBerryDeps side | 08:57:18 |
| Yureka (she/her) | so I'd say it's fine | 08:57:25 |
 leona | no, the fod hash didn't change | 08:57:33 |
| K900 | Yeah but they patched a bunch of lockfiles and now do we have to do that for everything | 08:57:37 |
| leona | the build just failed | 08:57:39 |
| Yureka (she/her) | do you have a reproducer I can look at? | 08:57:49 |
| K900 | OK wait two different issues | 08:57:54 |
| K900 | 4.14 changes FOD hashes | 08:58:00 |
| K900 | 4.13 just locks up | 08:58:03 |
| K900 | When you build yarn itself | 08:58:07 |
| K900 | On next | 08:58:08 |
| leona | https://github.com/NixOS/nixpkgs/pull/512685#issuecomment-4319558204 | 08:58:10 |
| leona | in https://github.com/NixOS/nixpkgs/pull/513745 they now patched the .yarnrc.yml | 08:59:02 |
| leona | so you need to revert this part for a reproducer | 08:59:13 |
| Yureka (she/her) | ok but it's not failing in the FOD phase, right? | 08:59:58 |
| K900 | Yeah | 09:00:02 |
| Yureka (she/her) | I don't see anything to be done on the fetcher side. the fetcher works correctly and you can detect all failures using nixpkgs-review/... | 09:00:34 |
| Yureka (she/her) | the fetcher's (and config hook's) job is to make sure the FOD does not randomly break, which it didn't | 09:00:52 |
| leona | IMO it's how https://github.com/NixOS/nixpkgs/blob/master/pkgs/by-name/ya/yarn-berry/fetcher/berry-4-offline.patch is intergrated into yarn? | 09:01:25 |
| leona | and this now longer works in this way by default? | 09:01:34 |
| leona | but I may be wrong | 09:01:54 |
| Yureka (she/her) | yes, this is the config hook | 09:03:54 |
