 Sandro 🐧 | the installer places a script to source in /etc/profile or so. Should be visible in the log | 13:11:55 |

 trofi | Does nix have a built-in to check if the path is/will-be in nix store? Right now nixpkgs tries to use regex against /nix/store like https://github.com/NixOS/nixpkgs/blob/e224f1b3db62680d7bae444717d0a733d372b556/lib/types.nix#L580 and fails miserably on strings built from CA derivations as they don't have the prefix: https://github.com/NixOS/nixpkgs/pull/375961#issuecomment-2613547575 | 06:35:28 |

 Ilan Joselevich (Kranzes) | We also have lib.isStorePath, not sure why the type isn't using it | 15:05:30 |
| trofi | Ah, nice! That one seems to work. | 19:11:32 |
| trofi | Tried to use it and it fails: isStorePath only returns true for exactly the store dirs, like /nix/store/foo, but not files within them like /nix/store/foo/bin/bar. | 19:16:30 |
| 26 Jan 2025 |
| Ilan Joselevich (Kranzes) | Can you not just do lib.hasPrefix builtins.storeDir | 01:13:18 |
| @aloisw:julia0815.de | That would match slightly more stuff (/nix/store itself and hidden files/subdirectories). Also it does not fix the issue at hand. | 07:14:54 |
| trofi | No, CA derivations don't have it as a prefix:
nix-repl> hello.outPath
"/1121rp0gvr1qya7hvy925g5kjwg66acz6sn1ra1hca09f1z5dsab"
| 12:41:26 |
| Ilan Joselevich (Kranzes) | So what's there to check that it's just /$sha256? | 13:14:27 |
| trofi | "^/[A-Za-z0-9]{52}.*" | 13:18:42 |
| trofi | Proposed the nixpkgs workaround as https://github.com/NixOS/nixpkgs/pull/377007 | 15:38:08 |
| Ilan Joselevich (Kranzes) | Ngl i kinda dislike it | 15:39:57 |
| Ilan Joselevich (Kranzes) | It gets rid of a lot of strictness just to support an experimental feature that almost nobody uses and that is implemented pretty badly | 15:40:42 |
| Ilan Joselevich (Kranzes) | You shouldn't punish the vast majority of nix users just because CA paths are represented stupidly | 15:41:20 |
 emily | why are they not rooted in the store anyway? | 16:05:17 |
| emily | using a path that might exist, in a namespace not owned by Nix, seems weird. | 16:05:29 |
| trofi | They are invalid paths anyway :) | 16:16:51 |

using a path that might exist, in a namespace not owned by Nix, seems weird. If they are unpredictable, they're very unlikely to exist. | 17:19:04 |
| @aloisw:julia0815.de | (Unlike, say /__corepkgs__ if you really want to fool Nix.) | 17:19:18 |
| emily | do I want to know what /__corepkgs__ is for? | 18:10:22 |
