Maybe this https://gitlab.haskell.org/ghc/ghc/-/merge_requests/11444 ?
Is there a specific set of issues you have in mind?
That sounds like precisely it, yes.
Maybe if I get the time I'll try applying the MR in Nixpkgs... | 17:34:35 |
 Teo (he/him) | There's also been a lot of work recently on making more boot libs easy to reinstall and on ghc-toolchain. Both of those should make everything cross related easier to implement in a nice way | 18:04:53 |

 Pierre Thierry | I'm trying to fix broken packages, starting with polysemy-zoo, I have the latest master from the nixpkgs repo, and the only files modified are broken.yaml and main.yaml in configuration-hackage2nix, but when I do:
./maintainers/scripts/haskell/regenerate-hackage-packages.sh
I get the following error:
hackage2nix: user error (Unexpected end-of-input, expecting JSON value)
Am I missing a step or doing something wrong?
| 13:53:54 |
 chreekat | So you modified json and now you're getting a "user error: invalid json"? :D | 14:17:34 |
 maralorn | Yeah, sounds like you made a syntax error in the yaml files. | 14:49:19 |
| Pierre Thierry | Well, I didn't think my changes could be the source but I checked anyway: I get the error with a clean working directory. | 16:30:42 |
| maralorn | I just checked out recent nixos-unstable and it seems to work. | 17:58:30 |

 sterni (he/him) | maralorn: do you have time to give https://github.com/NixOS/nixpkgs/pull/429212 a look over or should I just merge it and start an evaluation | 11:46:13 |

| sterni (he/him) | or others with relevant experience of course :p | 11:57:57 |
| maralorn | I can take a look later. | 12:29:00 |
| sterni (he/him) | Pierre Thierry: Feel free to open an issue about it, including enough information to hopefully reproduce the issue you're seeing. | 17:12:26 |

 dana | I need somethings from the https://github.com/NixOS/nixpkgs/pull/424162, which is now merged into staging. However, when I try to use it locally the caches aren't populated just yet, so I end up recompiling GHC. The caches are a bit confusing since staging or haskell-updates rev that I need don't have the cache, but it's not clear to me when are these changes going to end up in staging-next or master (which do have the caches).
Slightly unrelated question: how do things get merged from staging to staging-next in general? Because the https://github.com/NixOS/nixpkgs/blob/master/CONTRIBUTING.md#staging says that there should be a manual PR. However, I don't see anything similar when I search for PRs from staging to staging-next: https://github.com/NixOS/nixpkgs/pulls?q=is%3Apr+base%3Astaging-next+head%3Astaging+ | 12:17:46 |

When do these changes usually propagate to master? Or what ref/rev should I take to get the caches earlier?

| maralorn | https://hydra.nixos.org/jobset/nixpkgs/haskell-updates trick: pick the mentioned commit from the eval three days ago | 12:23:38 |

haskell-updates also gets cached, but there was a bag change today so you probably want a commit from a few days ago. Hmm, okay, thanks! I was trying to pull the last commit from the PR but it didn't have the cache.
What is a bag change? | 12:23:48 |
| maralorn | A big change typed on my stupid phone. | 12:24:23 |
| dana | big change - the default ghc upgrade from 429212? | 12:25:03 |
| maralorn | Regarding staging-next I think that branch gets created fresh at some point the PR that you are looking for will be staging-next -> master. | 12:26:42 |

 Alyssa Ross | It never gets recreated — staging just gets merged into it when it's time for a new cycle. | 12:33:19 |

It never gets recreated — staging just gets merged into it when it's time for a new cycle. How can I find commits/PRs that correspond to this? | 12:35:33 |
|  Marc Jakobi joined the room. | 12:37:24 |
| Alyssa Ross | git log --merges --grep="staging.*staging-next" origin/staging-next would probably be reasonably accurate | 12:37:33 |
| Alyssa Ross | Next staging-next won't be for at least a week, because we just started staging-next-25.05 | 12:38:11 |
| dana | You mean this one, right? https://github.com/NixOS/nixpkgs/pull/429274
And no more commits will be added to it, only fixes? | 12:41:14 |
