06:22 <cole-h> I've been meaning to ask the same question, since we put a pin in that conversation a few months ago. Probably a more appropriate place for that discussion would be in #nixos-borg (just so I don't miss it -- I check samueldr's logs for that channel ~every morning, which is harder for this channel as it's slightly faster-moving)

06:26 alp has joined #nixos-dev

06:34 <zowoq[m]> cole-h: I'd rather we continue the discussion in the PR or we make an issue for it.

06:37 <cole-h> Maybe an issue on the ofborg tracker, then?

15:58 <kloenk> How do I get rid of cache failure? I fucked up my daemon (repaired it now) but I still have a failure chached

15:59 <tilpner> kloenk: It's stored in /root/.cache/nix/binary-cache-*

15:59 <tilpner> But you can also try --option narinfo-cache-negative-ttl 0

15:59 <kloenk> root, or my user? I thought the cache is in the client?

16:01 <tilpner> root should be correct

16:01 das_j has quit [Remote host closed the connection]

16:01 ajs124 has quit [Remote host closed the connection]

16:01 <tilpner> Or whatever user your nix-daemon is running as

16:02 ajs124 has joined #nixos-dev

16:02 <kloenk> Just delete the db?

16:03 <kloenk> It must be the client (so my user) I'm 100% sure the nix daemon is not accessing the db for this cache failure

16:03 <tilpner> How do you tell?

16:04 <tilpner> The database is empty for my user, but not for root

16:04 Scriptkiddi has joined #nixos-dev

16:04 das_j has joined #nixos-dev

16:04 <tilpner> And it would make some sense for the daemon to cache narinfos, because it will also perform the substitutions

16:05 <kloenk> tilpner: I'm tapped into the socket connection. there is no cache failure info going over the socket, but my client says that

16:05 <tilpner> Yes, removal will work

16:05 <tilpner> Or well, does for me

16:05 <kloenk> Do we talk about the same cache? I'm talking about the flake eval cache

16:05 <tilpner> You didn't mention flakes at all

16:06 <kloenk> yeah, sorry. It's the only cache failure I ever encounterd

17:24 <flokli> LnL: gchristensen: do the ofborg darwin builders have xocde installed?

17:25 <flokli> I'm trying to build https://github.com/NixOS/nixpkgs/pull/93534 on another machine, but it seems to shell out to xcodebuild

17:25 <{^_^}> #93534 (by ajs124, 2 hours ago, open): python-gyp: update with python3 support + drop python2 dependency in nss build

17:25 <flokli> I'm not sure if that's supposed to work

17:26 <LnL> flokli: no, same with the hydra hosts xcode or clt isn't a requirement for nix and aren't allowed with sandboxing either

17:26 <flokli> LnL: so the sandbox should prevent shelling out to xcodebuild?

17:27 <LnL> yeah

17:28 <LnL> we do have xcbuild which provides compatibility with xcode but that's generally not needed

20:30 <__monty__> Licensing question. I'm talking to a company that releases a font which is free to use non-commercially. However, usually you have to register to download this font. They can provide a way to download the fonts without registering which would come with an amendment to the license explicitly allowing this on a per-platform/os/distro basis. I assume they want to provide per-distro urls to keep count of

20:30 <__monty__> installs per distro. Would this be acceptable for a nixpkgs package? Marked unfree, of course. The current package in nixpkgs is technically violating their license afaiui.

20:46 <gchristensen> we have some software in nixpkgs like that, I think it should be fine -- but evidence of this license amendment should be added to the nix expression

20:48 <clever> i think the teamspeak client has an example of that, a quote from an email

20:49 <__monty__> Is there a meta attribute to point to a license? Or does SPDX allow you to do so? They host pdfs of both the license and the amendments.

20:50 <cole-h> > :p lib.licenses.gpl3Plus

20:50 <{^_^}> { fullName = "GNU General Public License v3.0 or later"; shortName = "gpl3Plus"; spdxId = "GPL-3.0-or-later"; url = "https://spdx.org/licenses/GPL-3.0-or-later.html"; }

20:50 <cole-h> That's all a license is, so you could probably do something similar.

20:51 orivej has quit [Ping timeout: 256 seconds]

20:51 <__monty__> Defined in the package? Or should I PR lib.licenses?

20:52 orivej has joined #nixos-dev

20:52 <qyliss> if it's just for a single package I would just inline it

20:53 <qyliss> (the common thing seems to be to add to lib.licenses but I don't think filling that with single-use licenses is a good idea)

20:53 <gchristensen> agreed

20:53 <__monty__> Alright, thanks!

20:54 <cole-h> I'm of the same opinion.

20:56 <clever> my hydra-eval-jobs is segfaulting, and coredumpctl refuses to save a dump because it takes over 30sec to save!

20:56 <clever> after fussing with gdb, i got a backtrace:

21:04 <samueldr> hmm there may be an issue on the nixos hydra instance too

21:04 <samueldr> https://hydra.nixos.org/jobset/nixos/trunk-combined#tabs-errors

21:04 <samueldr> I'm not restarting it

21:04 <samueldr> https://gist.github.com/samueldr/defc7df66b6dd91ed344c378afa6f026

21:05 <cole-h> Ouch...

21:05 <samueldr> the new error messages may need a bit of work for hydra integration

21:06 <cole-h> Or just don't pretty-print if not to a tty

21:08 <eyJhb> Does Hydra use gvisor?

21:09 <clever> samueldr: i also cant get the most recent hydra to even deploy with nixops, the flake changes break everything

21:09 <clever> its rather ... flakey ....

21:20 alp has joined #nixos-dev

21:22 <clever> samueldr: i brute-forced the solution, i just kept evaling attrs in nix repl until it failed, then commented the problem one out, and now hydra evals just fine

21:22 <samueldr> which was?

21:22 <clever> nix-tools

21:22 <clever> from haskell.nix

21:23 <clever> 7 pkgs = import sources.nixpkgs haskellNix.nixpkgsArgs;

21:23 <clever> 251 # inherit (x86_64.haskell-nix) nix-tools;

21:23 <clever> thats enough to make hydra explode with 35,000 stack frames

21:25 <clever> should probably take things to #haskell.nix though, at this point
