C++ probably because nix is still in that language :( Was nix initially written in perl? 🤔 | 11:01:38 |
 Alyssa Ross | but C++ existed when Hydra was written | 11:01:48 |
 @trofi:matrix.org | Fetchers were probably in perl. | 11:02:11 |

Was nix initially written in perl? 🤔 large parts, yes | 11:02:13 |

Was nix initially written in perl? 🤔 No but you wouldn't write a webapp like hydra in c++ | 11:02:27 |

| das_j | Also yes, it partially was perl | 11:03:23 |
| @linus:schreibt.jetzt | oh actually https://github.com/NixOS/nix/milestone/6?closed=1 is a better overview. | 11:04:06 |
 @grahamc:nixos.org | Perl has very little code that justifies being written in C++, I'm pretty sure it was picked for the website because it both had a popular web framework and the Nix contributors had experience | 13:48:52 |

 samueldr | am I alone in thinking it is a surprising behaviour when executing hydra with foreman that evals being affected by the ambiant NIX_PATH is surprising? | 04:47:45 |
| samueldr | the eval used import <nixpkgs> {}, and nixpkgs was an input of the build (a git checkout) | 04:48:44 |
| samueldr | it ended-up trying to import <nixos-config> for its overlay, and failing on a further path import disallowed by restricted eval | 04:49:13 |
| samueldr | btw, I'm using a foreman-started hydra as a sort of better UX around nix-build for a complex project... it's hard to get a good bird's eye view of what is going on | 04:51:44 |

OK whomst do I poke here to get https://github.com/NixOS/hydra/pull/1243 merged Not to be too annoying but bump | 07:12:01 |
|  greaka changed their display name from greaka ⚡️ to greaka . | 09:25:58 |
| samueldr | ignore the fact that it's not a valid way to evaluate Nixpkgs | 21:18:26 |

| samueldr | am I missing something obvious with hydra jobset inputs? | 21:19:04 |

This is "working" as expected | 21:19:25 |

| samueldr | assuming the inputs work like NIX_PATH does, I would expect this to eval at least up to failing within the eval of Nixpkgs stuff | 21:20:36 |
| samueldr | hydra-eval-jobs returned exit code 1:
error: file 'nixpkgs/default.nix' was not found in the Nix search path (add it using $NIX_PATH or -I)

| samueldr | relatedly, I'm trying to simulate another more involved issue where similarly import <some-url-to-tarball> within hydra will try to import the raw tarball, but when provided as NIX_PATH to a norma Nix eval it unpacks it before making it available | 21:24:33 |
