 alexfmpe | * That PR has been merged, so you want haskell-updates branch really. Can't say I've tried HLS 2.10 yet and there were also a couple reports of seg faults over at #haskell-language-server:matrix.org so there might even be a new release soon | 12:47:38 |
| alexfmpe | also, haskell-updates has 9.8 as default ghc, but 9.12.2 is there and the default ghc912 | 12:49:04 |
| alexfmpe | I'm not sure exactly how/when the caching jobs work, but I expect as long as 9.12 isn't the default, you'll have cached compiler but not cached packages | 12:50:11 |

I'm not sure exactly how/when the caching jobs work, but I expect as long as 9.12 isn't the default, you'll have cached compiler but not cached packages Cache is populated from haskell-updates (and IIRC only from that branch). | 12:51:25 |
 maralorn | Well and from master of course. Although the list of jobs which get build on which branch is slightly different. | 13:03:15 |
| maralorn | Some central packages, e.g. hls are being cached for every (major) compiler version. | 13:03:46 |
| alexfmpe | noice | 14:00:41 |
| alexfmpe | yeah this is what confuses me, which does which | 14:00:55 |
| alexfmpe | I haven't gotten even 9.8 from cache on my mac on haskell-updates | 14:01:13 |
| alexfmpe | * I haven't gotten even 9.8 from cache on my m1 mac on haskell-updates | 14:01:39 |
| alexfmpe | * I haven't gotten even ghc 9.8 from cache on my m1 mac on haskell-updates | 14:02:11 |
| maralorn | Well builds also need to succeed of course. | 14:21:22 |
| maralorn | well compare pkgs/top-level/release.nix (ctrl+f haskell) with pkgs/top-level/release-haskell.nix | 14:26:42 |
 Profpatsch | Is there a shortcut for building an executable with pre-set GHC RTS params? | 14:26:49 |
| Profpatsch | In particular -Iw60 for small scripts to reduce the idle gc frequency | 14:27:04 |
| maralorn | Yes, you can pass RTS flags to set by default to ghc. | 14:27:27 |
| maralorn | e.g.: -with-rtsopts=-maxN2 | 14:28:01 |
| maralorn | * e.g.: ghc-options: -threaded -with-rtsopts=-maxN2 | 14:28:28 |
| Profpatsch | Ah you mean in the cabal file? | 14:28:43 |
| Profpatsch | I guess that works | 14:28:46 |
| maralorn | According to that we mainly build every ghc major release+hls on master and plenty more on haskell-updates. | 14:30:16 |
| alexfmpe | Huh so the darwin build is probably failing is that it? | 14:42:16 |
| maralorn | Oh, no. | 14:45:15 |
| maralorn | I think because of reasons which I would largely summarize under "Apple" we currently don’t build for any darwin target on haskell-updates. 😄 | 14:45:53 |
| maralorn | That was however a temporary mitigation for that fact that stuff was very fragged. I don’t know what would need to happen for us to re-enable them. | 14:47:05 |
| Alex | In reply to @profpatsch:augsburg.one
Ah you mean in the cabal file? The alternative, if you don't want to touch the Cabal file, is that you edit the cabal2nix output or override the package.
I think --ghc-options can be added to configureFlags? | 14:49:31 |
| Profpatsch | cabal file is fine | 15:03:05 |

Maybe what you're thinking of is packageOverrides: https://haskell4nix.readthedocs.io/frequently-asked-questions.html#how-to-override-packages-in-all-compiler-specific-package-sets So I would set it in my overlay, right? | 15:40:53 |
| Las | this is just what I wanted | 15:41:01 |
