 vcunat | Ah, I guess I should ask at #ofborg:nixos.org instead. | 07:37:13 |

 Sandro 🐧 | I merged a new usage of DeterminateSystems/magic-nix-cache like half an hour ago 😂 | 13:01:21 |
 yorik.sar | Would it be possible to retrigger this build? https://hydra.nixos.org/build/319408938 - it failed with segfault on configure phase in Hydra, but went pass that point just fine on my machine. Build didn’t finish for me yet though. | 17:01:50 |

| yorik.sar | @K900 thanks! Unfortunately, it still fails. Will look if there’s an issue about that already. Also ran into this issue with Hydra itself: https://github.com/NixOS/hydra/issues/1562 | 14:17:21 |
| vcunat | IIRC there are "imperfections" about logs on Hydra when a build gets retried. | 15:01:05 |
| vcunat | The worst part I guess is that binary cache indexes logs just by derivation, e.g.
https://cache.nixos.org/log/gf2lm8i875fqa55j3gix4rpxm5y8hp3j-itstool-2.0.7.drv
so it's not designed to hold multiple attempts. | 15:02:29 |
| yorik.sar | I don’t quite understand where Hydra gets the old log then. | 15:58:33 |
| yorik.sar | I also wonder how much space these logs take up in the cache bucket. | 15:59:30 |
| vcunat | Logs compress well. IIRC this was investigated when analyzing space usage (and considering garbage collection), and logs weren't taking a significant fraction of our S3 space. | 17:14:07 |
| vcunat | The hydra server also stores logs somewhere, like in local /nix/store or in the postgres? So you might be getting those instead from S3. | 17:14:42 |

| vcunat | But that dir suffers from the same design problem as the URL, I think. | 17:16:05 |
