@raitobezarius:matrix.orgraitobezariusbut I think the Lix team has almost no available Darwin expertise these days21:08:55
@emilazy:matrix.orgemilyoh no Docker21:09:05

oh no Docker

@raitobezarius:matrix.orgraitobezariusit's almost done21:09:20
@raitobezarius:matrix.orgraitobezariusjust some pnpm & wasm garbage21:09:24
@raitobezarius:matrix.orgraitobezariusbut i cannot fix release blockers and do that at the same time [and the 26 bazillion of things]21:09:40
@emilazy:matrix.orgemilythe Emily team's Darwin expertise is also oversubscribed 😔21:09:41
@emilazy:matrix.orgemilymuch as I would like to put work in21:09:46

realistically, how often CA certificates changes mid-builds?
I think we specifically started copying it to prevent this from causing trouble?

@gilice:matrix.orggiliceDownload console.patch10:10:18
@gilice:matrix.orggilice hi, random guy chiming in here, I got the console output of your default.nix to build.
here's a patch:
10:10:22
@opna2608:matrix.orgPuna Hi!
I see there's a host_cpu variable in meson.build where some fixups are being done to turn Meson's cpu_family() results to values that Nixpkgs expects for system parsing. Is that variable actually wired up to anything invisibly, or is it just completely unused right now?
I tried to add more fixups to it for POWER CPUs, but the system string stays wrong. Only if i change the host_system below it to actually use it do I get a correct system name printed.
11:52:13
@qyriad:katesiria.orgQyriad It determines the default builtins.currentSystem value Lix is compiled with, I believe 11:53:17
@opna2608:matrix.orgPuna I assume it should, but host_system is what's being used for that, and that just used cpu_family() 11:54:20
@qyriad:katesiria.orgQyriad Oh I see what you mean now 11:54:40
@qyriad:katesiria.orgQyriad that's a good question then, I'm not suredon' 11:54:51
@qyriad:katesiria.orgQyriad * that's a good question then, I'm not sure 11:54:56
@opna2608:matrix.orgPuna i think I submitted a theoretical fix for the POWER names? not super familiar with the gerrit workflow yet.
if host_cpu is supposed to be used there, should i make that a separate changelist thingy?

do you remember which commit / which thing introduced that?
14:27:51
@raitobezarius:matrix.orgraitobezarius moved back to the non optimized version in https://gerrit.lix.systems/c/lix/+/3765/4?tab=comments 14:27:56
@raitobezarius:matrix.orgraitobezariusand added a CL for the optimization14:28:00
@raitobezarius:matrix.orgraitobezariuswith a FIXME for defending against UDS attacks14:28:04
@aloisw:julia0815.dealoisw https://git.lix.systems/lix-project/lix/commit/cf756fdf3c1a804af726703a12ed2990ad6c2639 14:30:02
@aloisw:julia0815.dealoisw According to the commit message here the motivation was avoiding broken symlinks, but the linked commit doing the same for resolv.conf also cites changing file. 14:30:54
@emilazy:matrix.orgemilyI feel like the store thing would achieve a comparable optimization across platforms while solving any UDS / file changing / etc. worries (but I should stop saying this because I suspect there is complexity to arranging the store copy that i'm just missing :) )15:32:07
@emilazy:matrix.orgemilycopying all the time sounds great to me if Linux has to do it too though :P15:32:24
@emilazy:matrix.orgemilyhow do you select a range of lines to comment on in Gerrit?15:58:20
@emilazy:matrix.orgemilyI feel like I forget and have to remember how every time15:58:28
