 Robert Hensing (roberth) | So what we're left with is the "developer" use case | 12:06:15 |
 emily | it is "reasonably" pure since things are still addressed by hash but it seems to me the only way to get builds involving >40 GiB of assets without years of experimental work on the Nix end | 12:06:25 |
| Robert Hensing (roberth) | For development, presumably you want a quick build, so making asset processing fine grained with a derivation per asset would be the thing to do | 12:06:59 |
 magic_rb | To clarify, i dont have an immediate use case for this. It would be nice, but so far i dont have a game id be developing lol | 12:07:17 |
|  sinan changed their profile picture. | 12:07:52 |
| magic_rb | So this was more something i wanted to look at personally, but it seems i severely underestimated the complexity | 12:09:11 |
| Robert Hensing (roberth) | If you're ok with some eagerness for now, the complexity isn't so bad | 12:09:57 |
| Robert Hensing (roberth) | This one's the easiest to implement, and it can follow the LFS pattern | 12:10:20 |
| magic_rb | Honestly even the eager version would be nice, currently it just leaves a bunch of dangling symlinks | 12:10:45 |
| magic_rb | So option one, "deference it completely and return the file contents" | 12:11:07 |
| Robert Hensing (roberth) | yep | 12:11:16 |
| Robert Hensing (roberth) | That one can follow the structure of the LFS implementation | 12:11:40 |
| magic_rb | Can it be done as a plugin or does it have to be done in tree? | 12:11:59 |
| magic_rb | While experimenting a plugin would be much easier | 12:12:10 |
| Robert Hensing (roberth) | (oh, it quoted the whole message lol) | 12:12:11 |
| Robert Hensing (roberth) | I don't feel like plugins are easier because I don't think libfetchers plugins have been done, but I could be wrong | 12:13:00 |
| magic_rb | Well ill trust you on this one, i know nothing about nix's codebase, ill see if i get to this till nixcon | 12:13:35 |
| magic_rb | Thanks for the chat robert | 12:14:35 |
| Robert Hensing (roberth) | Glad I could help :) | 12:32:02 |

 aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | Dumb question, why is queryDerive in perl binding having the different output from nix derivation show? And the former sometimes doesn't exist, for example for FOD derivation | 03:35:44 |

| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | The left is from the second line of nix derivation show /nix/store/dc5vnmz4y7dmy2h5m1pri7ldpv2q4lv1-hyprland-0.49.0, and the right is from $store->queryDeriver("/nix/store/dc5vnmz4y7dmy2h5m1pri7ldpv2q4lv1-hyprland-0.49.0") | 04:18:57 |
| aleksana 🏳️⚧️ (force me to bed after 18:00 UTC) | I know it now. Same with https://github.com/NixOS/nix/issues/7562 | 04:38:09 |

| magic_rb | idk who i was talking to, maybe emily or aleksana but i was complaining about nix always copying my dotfiles to the nix store. So what happened just now is i did .dump of my nix DB, then .read into a fresh DB and it had 3 effects afaict:
- it shrunk from 599MB to 380MB ish
- nix GC completed no problem and it felt substantially faster on average, it wasnt randomly getting stuck
- nix no longer copies my dotfiles every time?

 dramforever | 1 can probably be done with vaccum | 19:06:59 |
| magic_rb | Probably | 19:54:28 |
