| siraben | Hi, I'd like to get hydra build logs and metadata in bulk, for analyzing regressions on Nixpkgs over time, who can I talk to for this? Happy to pay as well to offset the infra/compute cost. | 19:13:20 |
| siraben | data is used for non-commercial purposes | 19:14:13 |
 hexa | repeatedly or one-off? | 19:15:20 |
| siraben | one off | 19:18:29 |

 vcunat | You can get logs from the CDN, e.g.:
- get .drv path /nix/store/6xvsgsnlap9vhc4xhnzfyax9rz69n7f1-filterpath-1.0.4.drv
- get https://cache.nixos.org/log/6xvsgsnlap9vhc4xhnzfyax9rz69n7f1-filterpath-1.0.4.drv
| 05:53:59 |
| vcunat | Some metadata is in .narinfo, too. (the same CDN again)
$ nix eval -f. nix.outPath
"/nix/store/bnrjki4vg8lw5k8zcfvk9sshda2k1ydf-nix-2.34.6"

 John Ericson | BMG: can drv path in buildstep be non-null? | 00:24:30 |
| John Ericson | seems like that was just an oversight | 00:24:39 |
| John Ericson | I guess substitution steps could be screwed up | 00:26:18 |
| John Ericson | Mic92: I have a branch where I store all the deps in the db which is cool but I do wonder about storage requirements | 16:54:42 |
| John Ericson | I am realizing the current design where teh edges are all ephemeral and only the nodes remain is very cool for minimizing storage | 16:55:12 |
| John Ericson | even if it is not cool for figuring out what is going on from the webapp | 16:55:27 |
| John Ericson | (I ping Joerg kind at random I suppose, I am just posting into the void for whoever cares :)) | 16:55:57 |
 Mic92 | @Ericson2314:matrix.org: currently derivations get garbage collected and only a few generations are hold back. If do something similar, we should be good, no? | 17:31:44 |
| John Ericson | well we keep all the old steps | 17:32:00 |
| John Ericson | but yeah we can expire different parts of the data at different times | 17:32:11 |
| John Ericson | BMG: I have some interesting migrations on https://github.com/obsidiansystems/hydra/commits/build-step-by-drv-path this branch | 19:42:44 |
