@dramforever:matrix.orgdramforeveror maybe i'm spoiled by whatever this superior mailing list archive viewer is16:38:30
@dramforever:matrix.orgdramforeverapparently it's just called public-inbox16:39:10
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)so uh, one thread in 2019 and nothing since?16:47:06
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)Thats kinda disappointing16:47:12
@dramforever:matrix.orgdramforeverthere's an implementation https://inbox.vuxu.org/musl/20190120154154.GA23924@voyager/16:47:52
@dramforever:matrix.orgdramforever

with the best line of code i've seen this week

size = INT_MAX; //2GB ought to be enough for anyone
16:48:29
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)

Yeah, i found that a few hours ago, alpine uses that: https://gitlab.alpinelinux.org/alpine/aports/-/blob/3.22-stable/community/accountsservice/musl-fgetspent_r.patch

But fgetpwent_r is broken the same way

16:49:07
@dramforever:matrix.orgdramforeverunfortunately it does seem that you need to patch musl to get it16:49:08
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)its just a shim, i can inline the shim16:49:27
@dramforever:matrix.orgdramforeverokay you tricked me you wrote fgetspent_r twice 😆16:49:49

@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)OH16:49:59
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)shit16:50:00
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)sorry16:50:04
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all) *

matthewcroughan: i have copied the nixosTests.login and added security.enableWrappers = false + pwaccess stuff, and the test is succeeding. Its screaming at me and i am definitely doing things wrong, but this might be progress?

Bad news is, pwaccess uses fgetspent_r / ~~fgetspent_r~~ fgetpwent_r which are unavailable on musl. Not sure yet how i'll fix that pain

16:50:18
@dramforever:matrix.orgdramforeverokay but16:50:29
@dramforever:matrix.orgdramforeverthis alpine fgetspent_r is not _r16:50:42
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)yeah....16:50:51
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)we love hacks16:51:13
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all) anyways, if matthewcroughan has an idea to make pwaccess work on musl (e.g. writing a similar shim for fgetpwent_r too) then we may have an suidless musl login 17:11:50
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)i won't poke the musl part of this too hard for now17:12:06
@matthewcroughan:defenestrate.itmatthewcroughanif you wanted to, then matthewcroughan.cachix.org has a lot of cache 17:12:25
@matthewcroughan:defenestrate.itmatthewcroughanI want to host and sign a musl hydra at some point 17:12:40
@grimmauld:grapevine.grimmauld.deGrimmauld (any/all)this needs basically no cache, its like 25 packages (admittedly systemdLibs takes a few minutes, but still very manageable). I don't have a setup to run musl VM tests, i am missing nix expressions for that, not necessarily cache17:13:21
@matthewcroughan:defenestrate.itmatthewcroughanBut do I even need to run hydra? Can't I just run something like https://git.snix.dev/snix/snix/src/branch/canon/ops/machines/snix-cache ?17:13:17
@matthewcroughan:defenestrate.itmatthewcroughanThere is no way to run a musl vm test because of only one thing17:13:38
@matthewcroughan:defenestrate.itmatthewcroughanpytest breakage on staging-next17:13:45
@matthewcroughan:defenestrate.itmatthewcroughanhttps://git.snix.dev/snix/snix/src/branch/canon/ops/machines/snix-cache17:13:52
