| @symphorien:xlumurb.eu | hello, I'm trying to understand what code paths hydra.nixos.org is taking to upload nars to s3. dwarffs relies on this if branch to be taken https://github.com/NixOS/nix/blob/master/src/libstore/binary-cache-store.cc#L207 but this option is off by default https://github.com/NixOS/nix/blob/master/src/libstore/binary-cache-store.hh#L21 and I don't see it enabled there https://github.com/NixOS/nixos-org-configurations/blob/master/delft/hydra.nix#L33 Any idea where it is set?

 Arian | Hello. I'm trying to understand the difference between `store_uri` and `server_store_uri`. Neither option is documented. But if i look at the hydra source code if `server_store_uri` is set `store_uri` is ignored. However that makes the NixOS Hydra config non-sensical as its not pointing to the s3 bucket anymore.
https://github.com/NixOS/nixos-org-configurations/blob/72adc59c5ba946c3d4844a920e9beefae12bbd49/delft/hydra.nix#L33 | 12:34:13 |
| Arian | The only reference in the source code is here:
https://github.com/NixOS/hydra/blob/082495e34e094cae1eb49dbfc5648938e23c6355/src/lib/Hydra/Helper/Nix.pm#L532 | 12:35:21 |
| Arian | But doesn't that mean that the above config results in hydra trying to push to https://cache.nixos.org which as far as i know is read-only? | 12:35:47 |
| Arian | Oh wait. This is not actually used for pushing? | 12:39:35 |
| Arian | I see | 12:40:37 |
| Arian | Just used for serving files; it seems. | 12:40:47 |
| Arian | So how do you configure workers to push to cache? | 12:40:57 |
|  @clerie:bau-ha.us joined the room. | 12:51:36 |
 vcunat | Workers on hydra.nixos.org do not push to cache. | 13:00:53 |
| vcunat | The queue runner collects results, compresses signs and pushes. | 13:01:38 |
| vcunat | (I hope I didn't get some details wrong, but it shouldn't be too wrong.) | 13:01:58 |
| Arian | Where is the queue runner configured to push to cache? | 13:30:14 |
| Arian | (context I'm trying to set up Hydra to push to cache but can't figure out from the docs or the source code) | 13:30:31 |

Where is the queue runner configured to push to cache? They use a custom script for that iirc, not the built-in s3 code | 13:30:48 |
| vcunat | Custom script is used for channel updates, but normal binaries of built packages don't use that one. | 13:33:58 |

| Arian | Oh mystery solved GitHub code search is just bad | 12:57:57 |
| Arian | Hydra-queue-runner pushes to store_uri | 12:58:09 |
