@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?

I think we specifically started copying it to prevent this from causing trouble?
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
@emilazy:matrix.orgemilyah you select in the code rather than the gutter15:58:37

i mean, the optimization is dangerous for now :D

with my current proposal, bindPath would follow the symlink I believe
16:02:37
@raitobezarius:matrix.orgraitobezariusso broken symlinks would surface as an exception and break the setup16:02:44
@raitobezarius:matrix.orgraitobezariusbindPath(source symlink, target, {.followSymlinks = true}) degrades to copyFile(source, target, {.followSymlinks = true}) actually16:03:12
@raitobezarius:matrix.orgraitobezarius(with the createDirs in addition on the base dir)16:03:18
@raitobezarius:matrix.orgraitobezariusbut ok for the changing files16:03:38
@raitobezarius:matrix.orgraitobezarius K900 explain yourself 16:03:41
@raitobezarius:matrix.orgraitobezariusdid you notice files changing on the fly or not mid-builds?16:03:49
@raitobezarius:matrix.orgraitobezarius emily fwiw, i'm redoing the testing stuff 16:04:10
@k900:0upti.meK900 What 16:04:22
@raitobezarius:matrix.orgraitobezariusi'm going to split into a sandboxed-ca.sh and unsandboxed-ca.sh test suite16:04:22
@emilazy:matrix.orgemilybecause of issues with Darwin sandbox testing?16:04:36

because there's no such thing as building in a diverted store with Darwin
