 ners | maralorn any thoughts? | 09:51:30 |
 maralorn | I am sadly quite unfamiliar with the policys around hydra timeouts. I guess there have to exist exceptions for something like chromium? But I think in Haskell world we never had one? | 10:06:57 |

 sterni | ners: in principle the timeout is configurable per derivation. That comment is from 2021, though, so it may no longer be accurate for the builders we currently have. Currently, it doesn't make a difference since haskell-updates is not tested on aarch64-linux at all. I don't know when/if that is going to change. Also, haskell-updates is relatively disconnected from master these days, so you will get cache misses even on x86_64-linux (haskell-updates is for catching regressions primarily, not populating the binary cache). Feel free to open a PR adding jobs for pkgsStatic haskell to release.nix or maybe release-cross.nix which are intended for testing/populating binary cache on master. | 09:54:04 |
| sterni | going to merge h-u this evening probably | 16:01:25 |
| sterni | staging-next cycle is probably starting soon | 16:01:36 |
| maralorn | @sternenseemann:systemli.org At this point I have the feeling our rotation is kinda broken. | 16:43:52 |
| maralorn | As in theoretically it's my two weeks to do the merging. | 16:44:47 |
| maralorn | I mean I am not complaining. | 16:45:06 |
| maralorn | But I think in the longterm its better for everyone if we spread this on multiple shoulders. | 16:46:26 |

| sterni | I'm really bad at putting up my feet when it's not my turn unfortunately | 10:37:37 |
| maralorn | Yeah, but also since I got used to do doing the stuff I 1) got slower and 2) am not even sure I know how to do it now. 😆 | 11:08:07 |
 woobilicious | I'm trying to get a broken package to build (glft-codec) currently it's complaining about Aeson being too new, the currect version has a <2.2, but Aeson is on 2.2, I assume it'll just work if I can modify the symantic versioning but I can't figure out how to get it to work, I cloned the repo but flakes are complaining about the files missing (probably due to submodules), I wonder what I should do here before I dig myself in to a bigger hole. | 17:05:16 |
| maralorn | @woobilicious:matrix.org Apply haskell.lib.doJailbreak to your package. No need to clone or patch7 | 17:19:58 |
| woobilicious | thanks I'll try that. | 17:21:09 |
| maralorn | Plenty of examples in nixpkgs if you grep | 17:22:57 |
| woobilicious | brillant it worked, only issue was tests failing due to missing asset files, disabled tests and imports are working | 17:37:26 |

| syd installs gentoo (they/them) | Hey there! I hope some questions are appreciated. I'm trying to bump nix-tree (after asking the developer a while back to bump in hackage https://github.com/utdemir/nix-tree/issues/114#issuecomment-2888634183 ) assuming it would get updated eventually by nixos maintainers and the file says that you should use the regenerate-hackage-packages.sh but that fails on my local machine - I'd like to get in touch with the people maintaining that and assumed there was a Haskell Matrix channel maybe (there aren't a lot of GitHub issues around Hackage/Haskell lately if I'm not mistaken). | 18:51:28 |

 teo (they/he) | I was profiling eval time of nixpkgs recently and I noticed that a lot of time was spent doing hasPrefix when evalling the haskell package set. I think this is caused by the hasPrefix call to check if stuff is part of amazonka and each call of hasPrefix re-checks if the needle is a path lol https://github.com/NixOS/nixpkgs/issues/419216
We could optimise the hasPrefix call, but maybe we should just add the list of amazonka packages to this file rather than traversing the entire haskell package set?

how does one even do this? I always wondered
