@grahamc:nixos.org@grahamc:nixos.orgI think there is/was an alert on jobs that are taking a long time: https://monitoring.nixos.org/grafana/d/j0hJAY1Wk/in-progress-build-duration-heatmap?orgId=1&refresh=30s11:40:15
@grahamc:nixos.org@grahamc:nixos.orgyeah: https://monitoring.nixos.org/prometheus/alerts maybe we could get it posting to matrix11:40:37

fwiw it doesn't look like a capacity issue at the moment, since there are macs that are able to take work but aren't given any

Then something is wrong.

      "x86_64-darwin" : {
         "runnable" : 8939,
         "running" : 55,
         "waitTime" : 981988989
      },

@grahamc:nixos.org@grahamc:nixos.org yeah ... I have found runnable to be misleading ... but I don't remember the why ..... 11:44:26
@grahamc:nixos.org@grahamc:nixos.orgI've done autoscaling based on runnable andended up running dozens of totally idle machines for days as a result11:47:59
@grahamc:nixos.org@grahamc:nixos.orgI have a client facing similar mysterious issues and wants to look in to them ~soon, but not yet11:51:24
@baloo_:matrix.orgbaloohttps://github.com/NixOS/nixpkgs/pull/137197 this should fix the dns resolution failure on hydra16:06:24
@grahamc:nixos.org@grahamc:nixos.orgMaybe we can get Eelco to do a release instead of apply patches16:10:19
@vcunat:matrix.orgVladimír ČunátWell, it's relevant what nix gets deployed to the machines, not what we have in nixpkgs.16:10:27
@vcunat:matrix.orgVladimír Čunát(at least for hydra.nixos.org failures)16:10:38
@vcunat:matrix.orgVladimír Čunát * (at least for hydra.nixos.org failures, of course you can get the same anywhere else as well)16:12:01
@rick:matrix.ciphernetics.nlRick (Mindavi)It's time for a release anyway, he wrote it on discourse too16:16:52
@rick:matrix.ciphernetics.nlRick (Mindavi)I guess they still want to do some tickets, but at some point it would be good if there was a stable 2.416:17:28
@rick:matrix.ciphernetics.nlRick (Mindavi)Oh, a 2.3 release of course :)16:17:47

I mean, whichever is the fastest is fine by me :) I was mostly chasing r13y myself, and I know it pulls nixpkgs version.

@sternenseemann:systemli.orgsterniThe status.nixos.org page seems to behind? nixos-unstable is at bbbe2b35f736d039884e082ecc6d6e631e126029, but it says 4f6d8095fd51954120a1d08ea5896fe42dc3923b13:45:55
@sternenseemann:systemli.orgsterniah no the channel is still behind, but the nixos-unstable branch in nixpkgs is ahead of that?13:46:34
@lukegb:zxcvbnm.ninjalukegb (he/him)that comes from https://nixos.org/channels/nixos-unstable/git-revision14:21:24
@sternenseemann:systemli.orgsterni

seems like the population of the branch should be tied to the channel update service?

> git fetch origin && git rev-parse origin/nixos-unstable

@zimbatm:numtide.comJonas Chevalierthat was supposed to be fixed by https://github.com/NixOS/nixos-channel-scripts/pull/4914:39:54
@lukegb:zxcvbnm.ninjalukegb (he/him)Lemme just PURGE all the channels out of Fastly14:40:50
@sternenseemann:systemli.orgsterniah right it's the caching problem that makes more sense14:41:32
@zimbatm:numtide.comJonas Chevalierpurge sent14:42:04
@lukegb:zxcvbnm.ninjalukegb (he/him)status.nixos.org seems happier now14:42:46
@zimbatm:numtide.comJonas Chevalierplease ping me if you see more caching issues in the future14:43:59
@baloo_:matrix.orgbaloofor what it's worth, s-maxage only affects the first cache15:53:01
@baloo_:matrix.orgbalooa Cache-Control: header would serve the same purpose, and allow each layer to implement the same strategy.15:53:27
@baloo_:matrix.orgbalooshould someone (entreprise user) have another cache in between, he would not see the benefits15:53:55
@baloo_:matrix.orgbalooI think it would make sense to juste use max-age and not s-maxage15:54:44
@baloo_:matrix.orgbaloo * a max-age in the Cache-Control header would serve the same purpose, and allow each layer to implement the same strategy.15:55:11
