 emily | https://github.com/risicle/nix-heuristic-gc but requires atime | 20:46:24 |
| emily | it sounds like you want keep-derivations and keep-outputs mainly thougj | 20:47:01 |

it sounds like you want keep-derivations and keep-outputs mainly thougj That's good-enough to start, but it'd keep build deps for all gcroots right?
I'll continue the 3rd party GC impl, it's really just a couple of SQLite statements and some subprocessing :) | 20:56:02 |

Edit: wouldn't wanna rely on atime though :p
| 20:57:07 |
| emily | yes, but I mean it beats losing stuff unless you're low on disk | 20:58:21 |
| emily | and Nix with low disk space is misery | 20:58:44 |
| lillecarl | Agreed 😁 Thanks for the feedback | 21:03:41 |

 K900 | Feel like I must have asked this before | 06:54:35 |
| K900 | But has anyone looked into what it would take to make negative/fractional speedfactor a thing | 06:54:50 |
|  silent_water joined the room. | 14:43:35 |
 raitobezarius | I think so | 15:00:59 |
| raitobezarius | And flokli just archived it because he's not using it | 15:01:04 |
 Sergei Zimmerman (xokdvium) | Does Lix want a port of https://github.com/NixOS/nix/pull/13987? | 17:32:02 |
| raitobezarius | Would be glad yes :) | 17:54:22 |
 aloisw | emily (@emilazy:matrix.org) what is going on with the toml11 bump? I wasn't subscribed to the latest PR and now it looks to have been merged… into staging? | 18:36:01 |
| emily | yes, it rebuilds all NixOS tests for obvious reasons | 18:36:33 |
| emily | and we need it only in tandem with CMake 4 which is about to land in staging | 18:36:41 |
| emily | so putting it there to avoid unnecessary test rebuilds | 18:36:48 |
| emily | (otherwise it'd need catching the kernel updates train or something which didn't feel necessary) | 18:36:57 |
| emily | I guess the Lix Git bump would have to target staging too then, though. but we're about to start the staging-next cycle, so not too bad, hopefully? | 18:37:23 |
| emily | (well, "obvious". most tests probably shouldn't depend on Nix. but anyway.) | 18:37:37 |
| aloisw | I'll probably update the patch to support both and drop it on unstable on the next update after staging-next merge. | 18:38:02 |
| emily | ok, that works. sorry for the churn, didn't think the couple week's delay would be a big deal | 18:39:04 |
| aloisw | No it's not a big deal, I was just surprised what happened without me knowing (mostly due to my own mistake of not subscribing to the latest PR). | 18:40:09 |
| emily | sorry :) I think I pinged you in here a couple days ago wrt if you'd be able to update the Git version PR after merge | 18:42:31 |
| emily | but should have followed up again | 18:42:37 |
| aloisw | Yes and I didn't subscribe to the PR so didn't notice that you did in fact merge. | 18:42:55 |
| emily | right | 18:43:01 |
| emily | I've sent like twenty PRs for CMake 4 stuff in the past week or so, it's been a bit hectic | 18:43:23 |
