 vcunat | Ah, I misread that. OK. | 12:04:20 |
| vcunat | It does happen commonly on Hydra that we build the same-hashed derivation twice in parallel. | 12:06:02 |
| vcunat | * It does happen commonly on Hydra that we build the same-hashed derivation twice in parallel (and both succeed). | 12:06:09 |
| vcunat | I'm not sure what exactly happens in that case. But even so. | 12:06:26 |
 BMG | which would account for same nar but multiple narinfos? | 12:06:29 |
| BMG | assuming the build output was bit-wise reproducible | 12:06:48 |
| vcunat | They often are not, but I'm not sure that really affects the count of re-uploads. | 12:07:23 |
| vcunat | It doesn't affect the (S3/URL) paths. | 12:07:39 |
| BMG | Happy to jump on a call a bit later and poke through this dataset together | 12:15:23 |

 Mic92 | In reply to @brian:bmcgee.ie
But wouldn't that mean more nars than narinfos? You can end up with more narinfos if you produce the very same build-output. | 15:13:26 |
| Mic92 | Ah vcunat said this already | 15:13:48 |
 dramforever | i am pretty sure this is wrong | 15:14:38 |
| dramforever | narinfo is per path, nar is whatever | 15:14:44 |
| dramforever | so you'll have one narinfo per output | 15:15:15 |
| dramforever | protocol-wise the nars doesn't matter, you just need to point the URL in narinfo to something | 15:16:15 |
| dramforever | i think it just happens that nix defaults to using a hash of the nar contents | 15:16:29 |
| dramforever | or something like that | 15:16:33 |
| dramforever | i wonder if we have a bunch of test derivations that just create an empty file at $out and that's why we have way more narinfo than nar | 15:17:37 |

 John Ericson | now that Hydra repo has been upgraded to a fewer Nixes, should we re-deploy? | 15:50:05 |
