 kenran_ | (Mind you I'm also a first-time Hydra user, so there might be gaps in my understanding, but so far everything is working in my end.) | 08:10:58 |
 jackdk | But because the flake completely specifies its inputs, ISTM that you don't need the separate spec.json to declare which inputs you want in NIX_PATH or whatever | 08:11:53 |
| kenran_ | If you have private repos, then the hydra user on your server needs access via SSH. I've just added a special GitLab user and SSH key pair on the server in /var/lib/hydra (I think that was the path). | 08:12:35 |

But because the flake completely specifies its inputs, ISTM that you don't need the separate spec.json to declare which inputs you want in NIX_PATH or whatever Yeah, that sounds about right. I've never used spec.json; feels like hydraJobs make that obsolete for flake projects. | 08:13:16 |
| jackdk | Yeah it looks like spec.json does everything flakes do, but worse. Consider https://github.com/qfpl/reflex-workshop/blob/master/spec.json : it says "go evaluate release.nix from input reflex-workshop, setting <nixpkgs> and <reflex-workshop> in NIX_PATH. The attrset that the evaluation returns defines the jobs to actually run. | 08:16:50 |
| kenran_ | Ah yes. Just use the flake output type and enjoy :) | 08:17:27 |
| kenran_ | Sadly the NixOS tests I've written fail in my Hydra instance and I don't know why. I'll wait and see if anyone answers in the NixOS channel first, then re-post here in full detail. In essence all my tests use a postgresql service which after some time leads to
machine # [ 336.433468] postgresql-pre-start[896]: Success. You can now start the database server using:
machine # [ 336.452698] postgresql-pre-start[896]: /nix/store/6cn4h4icjjvg9yqx8iy55hvmqbq0jj2j-postgresql-10.21/bin/pg_ctl -D /var/lib/postgresql/10.0 -l logfile start
machine # [ 337.181043] systemd[1]: postgresql.service: Failed with result 'timeout'.

| kenran_ | Locally they're running just fine, so I'm at a loss. It's a flake project with everything pinned down and supposedly reproducible. | 08:19:46 |

evaluation hasn't started for 13h; seems like something is wrong https://hydra.nixos.org/jobset/nixos/trunk-combined it came through ✅ | 13:49:28 |

| kenran_ | I'm trying to create a minimal example for my Hydra/PostgreSQL problem mentioned above now, mainly just using a postgresql_10 service and waiting for the unit to come up. This is what usually seems to fail on my Hydra, but not locally. | 10:31:10 |
| kenran_ | Hum, of course the minimal example works as expected. The only thing I can even think of is the pin. | 10:58:25 |
| kenran_ | But then it stresses me out that the same nix build runs fine locally. | 10:58:45 |
