 atoix | Has anyone been using uv2nix for packaging Python apps? I tried replacing poetry2nix with uv2nix and cant get it to work. | 12:16:06 |
 K900 | #pyproject.nix:blad.is is the room for that | 12:17:47 |

 John Ericson | that sounds good, but is also funny because I was thinking about the opposite --- leaving the sandboxing code in C++ and the nuking all the other C++ it doesn't need | 21:01:00 |

| John Ericson | Las: xokdvium say hi! | 21:01:54 |
| John Ericson | since I have pinged you both about the goal reworking | 21:02:05 |
 Las | hi again | 21:02:09 |
| John Ericson | I am not quite sure how to divvy up the work, but I am quite sure there is plenty all 3 of us 😅 | 21:02:51 |

| John Ericson | (the exact sandboxing / running code is a bit of a delicate thing I am inclined to poke gently, leaving mostly as a black box, per the above. The goal logic however I am pretty sure is junked up and I am quite happy to take an axe to it :). Thanks to Las's coroutines reworking is is easier to refactor now too) | 21:04:40 |

| John Ericson | one way to go about it would be to duplicate DerivationGoal for the plane-build/repair/check cases, and then factor out the commonalities from first principles. but it is a bit of a scary large 3x code explosion in the interim | 21:06:20 |
| John Ericson | https://github.com/NixOS/nix/issues/12607 here is one other thing that is unrelated to CA / dyn-drv, and so lower priority for me, but a fun one-off project to tackle if anyone is interested | 21:14:25 |

 Picnoir | Hey!
There's a deriver field in the internal DB ValidPaths table. After a brief look in the source, I can see it populated from the narinfos for substitutions and from the builders for local builds.
I see that it's sometimes omitted, but can't pinpoint where it's omitted and why it can be omitted. | 08:23:09 |
| Picnoir | Are there cases where some builds don't have drv files? Do anybody here happen to know why some validpaths seem not to have derivers? | 08:23:45 |

 Ilan Joselevich (Kranzes) | Hah, this valid paths thing | 08:35:27 |
| Ilan Joselevich (Kranzes) | there's a couple of issues about it | 08:35:47 |
| Ilan Joselevich (Kranzes) | I remember that we also were confused about that when working on tvix | 08:36:44 |
| Ilan Joselevich (Kranzes) | Let me try to hunt down the notes | 08:37:01 |
| Picnoir | Thanks :) | 08:37:33 |
 flokli | I think not all narinfos in cache.nixos.org have a deriver set, and even less have the drv itself uploaded in the binary cache too. | 08:37:54 |
| Picnoir | Do you know why the deriver is not set? Is it related to the drv file being uploaded to the cache or not (if I remember correctly, there's a flag in the nix config for that)? | 08:39:19 |
| Picnoir | * Do you know why the deriver is not set? Is it depending of the drv file being uploaded to the cache or not (if I remember correctly, there's a flag in the nix config for that)? | 08:39:36 |

| flokli | It might be a hydra setting | 08:41:57 |
| flokli | I'm not entirely sure, sorry | 08:42:05 |
| Ilan Joselevich (Kranzes) | i suddenly dont remember if the valid paths thing is the same as the valid = true field | 08:43:26 |
| Picnoir | Hmm, could this be related to builtins 🤔 | 08:44:40 |
