 WeetHet | Why is checkPhase a part of the derivation build process? It feels like having another derivation which is being fed with the intermediates of the package derivation so disabling/experimenting with tests wouldn't require rebuilding the derivation is a better idea? | 14:39:14 |
 emily | yes in principle, but many technical issues | 14:55:35 |
| emily | intermediates can be huge, for one thing | 14:56:38 |
| emily | installCheckPhase is easier to factor like this | 14:56:38 |
| WeetHet | Some derivations take 1h+ to build and debugging checkPhase is basically impossible | 15:04:14 |
| WeetHet | I can probably run nix develop and execute phases yourself but it's a pain and I would rather prefer that I don't | 15:05:29 |

 Tristan Ross | You can use the --keep-failed flag and then try debugging it through the tmp directory it put the build in. | 15:06:32 |
| WeetHet | The environment isn't preserved though | 15:07:41 |
| Tristan Ross | In reply to @weethet:catgirl.cloud
The environment isn't preserved though It saves the environmental variables | 15:08:20 |
| Tristan Ross | You can source those | 15:08:28 |
| WeetHet | Wait it does? | 15:08:44 |
| Tristan Ross | Yes | 15:08:51 |
| emily | what would you do to debug/fix it that wouldn't change the original derivation anyway? | 15:08:57 |
| Tristan Ross | env-vars is the file | 15:09:10 |
| WeetHet | Skipping tests that require network/flaky tests | 15:09:33 |
| WeetHet | To be fair, it's probably a non-issue when you have something like crate2nix | 15:10:33 |
| WeetHet | * To be fair, it's probably a non-issue when you have something like crate2nix, since rebuilds don't take that much | 15:10:44 |
| emily | fair enough | 15:11:04 |
| WeetHet | I still wish there was a way to make each phase it's own derivation without needing to copy the build folder ten times | 15:11:47 |
| WeetHet | * I still wish there was a way to make each phase its own derivation without needing to copy the build folder ten times | 15:11:53 |
| emily | yes, it would be good. it requires much more fundamental changes than Nixpkgs can do though | 15:13:04 |
| WeetHet | On the other hand, again, copying isn't such a big deal with modern CoW filesystems | 15:14:42 |
| emily | it would go from not in the store to in the store, so usually you wouldn't be able to CoW | 15:19:19 |
| emily | (even when you have /nix/tmp and /nix/store on the same backing partition, there are technical reasons related to the bind mount stuff why it doesn't actually work on Linux) | 15:19:43 |
