@grimmauld:grapevine.grimmauld.deGrimmauld (any/all) Quick heads-up:
I believe https://git.lix.systems/lix-project/lix/src/commit/e101400359558ec89f0a3afa29631ca1b6546fd3/lix/libutil/processes.cc#L20-L22 should be unconditional. On glibc gcc this header is included implicitly. On musl llvm, that include is needed or otherwise SYS_capset (https://git.lix.systems/lix-project/lix/src/commit/243836ed0a0b963eebd033d109e6cb817d67fde4/lix/libutil/processes.cc#L414) is undefined.

On my dev machine I'm getting:

+(tarball.sh:31) nix-build -o /tmp/nix-test/tarball/result -E 'import (fetchTarball { url = "file:///does-not-exist/must-remain-unused//tmp/nix-test/tarball/tarball.tar"; sha256 = "sha256-PRgXPIzueCAIFHesj5pSLlDYbJsrGmUD8B9gpbs9p9Q="; })'
++(tarball.sh:36) mktemp -d
+(tarball.sh:36) export HOME=/tmp/tmp.0S4oIlI3Xo
+(tarball.sh:36) HOME=/tmp/tmp.0S4oIlI3Xo
tarball.sh: line 37: TMPDIR: unbound variable

Seems like function tests need to provide a sensible default for TMPDIR if it's not set

@raitobezarius:matrix.orgraitobezariusCan you open an issue with this trace so I don't forget about it? Thanks!00:03:55

@olivia:computer.surgeryolivia changed their profile picture.00:23:19
@xokdvium:matrix.orgSergei Zimmerman (xokdvium)Also any clue as to what's going on here? https://buildkite.com/lix-project/lix/builds/5888/steps/canvas?sid=019a8f19-65cf-4acd-9593-5d6bcd790abf#019a8f19-668b-4cbb-99c2-e68a72269606/18-32 The error message is coming from the host lix and not the one that's being built? Seems fucked00:25:14
@raitobezarius:matrix.orgraitobezariusI am going to take a look, I hope I didn't fuck up something with my recent infra work00:28:24
@raitobezarius:matrix.orgraitobezariusNormally I didn't touch this host neither its daemon setup00:28:35
@shalokshalom:kde.orgShalokShalom joined the room.07:52:34
@shalokshalom:kde.orgShalokShalomThe email confirmation for your git doesn't let me in, so I drop this here: https://nix-community.github.io/home-manager/index.xhtml#sec-usage-gpu-non-nixos This new mode for GPU support got merged last week. You might wanna update the README, that speaks about NixGL (only)07:53:37

@raitobezarius:matrix.orgraitobezarius aloisw hi there, we finally released 2.94.0, could I have you do the usual packaging on nixpkgs if you have some time to spare? 21:54:07
@raitobezarius:matrix.orgraitobezariusblog post will follow as well21:54:10
@raitobezarius:matrix.orgraitobezariusinstallers were done this time21:54:12
@raitobezarius:matrix.orgraitobezarius(i'm in the process of proofreading the release notes again and preparing the blog post)21:54:22
@just1602:systemli.orgjust1602 @raitobezarius:matrix.org: has the module been upgraded because it was giving a warning when I upgrade to 2.95 dev? I can take a look if it's not 22:49:18
@raitobezarius:matrix.orgraitobezariusi don't think the module has been upgraded22:50:38
@raitobezarius:matrix.orgraitobezariusi also need to really clean up that module because i only want to keep it for nightly builds nowadays22:50:56
@niko:nrab.lolniko ⚡️RE: macOS panic in releng - is there a public reproducer somewhere? I'd like to see what's going on there if you can crash it consistently23:29:44
@raitobezarius:matrix.orgraitobezarius jade_ your work ^ 23:35:24
@raitobezarius:matrix.orgraitobezariusbasically, it happened every time jade did nix copy s3://production23:35:34
@niko:nrab.lolniko ⚡️ The more info the better, though for starters I guess just knowing nix being lix from head or latest stable (or whatever else) should be enough 23:37:40

@raitobezarius:matrix.orgraitobezarius niko ⚡️ i think she was using a 2.93.3 version but don't quote me on that 02:42:09
@just1602:systemli.orgjust1602

It's not urgent at all, but I tried to push a CL using the recent jj gerrit upload command, and I didn't get any error, the status of the command seems ok, but the CL doesn't show up on gerrit:

❯ jj gerrit upload -r y

Found 1 heads to push to Gerrit (remote 'origin'), target branch 'main'
