@glepage:matrix.orgGaétan Lepage Hi zowoq!
It looks like buildbot is now failing to run our CI (affects all PRs): https://buildbot.nix-community.org/#/builders/26/builds/6249
Any idea?

@mattsturg:matrix.orgMatt Sturgeon

Seems related to our buildbot-nix.toml, which defines attribute = "ci.buildbot".

This has been working fine until today, so maybe the way the attribute config option is handled has changed recently?

@mattsturg:matrix.orgMatt Sturgeon

Could it relate to buildbot: 4.2.1 -> 4.3.0?

Or maybe fix all types broken by buildbot 4.3?

@domenkozar:matrix.orgDomen Kožarcould anyone merge https://github.com/nix-community/crate2nix/pull/401 :)20:32:12
@domenkozar:matrix.orgDomen Kožar* could anyone merge https://github.com/nix-community/crate2nix/pull/401 - I'm getting lots of input warnings otherwise20:32:29
@khaneliman:matrix.orgAustin HorstmanWeird... all of our PRs in HM show a green check on eval and no build failure, even though I see the same eval errors in my HM buildbot evals. 21:08:31
@zowoq:matrix.orgzowoq I've reverted the community buildbot to a working commit. cc Mic92 21:58:36
@glepage:matrix.orgGaétan LepageThanks!22:09:12

@joerg:thalheim.ioMic92 @zowoq:matrix.org: unclear if this relates to anything that changed in buildbot. Rather looks like nix-eval-jobs output has unexpected output? https://github.com/nix-community/buildbot-nix/blob/main/buildbot_nix%2Fbuildbot_nix%2F__init__.py#L207 03:42:27
@zowoq:matrix.orgzowoqThe buildbot-nix toml shouldn't be included in the nix-eval-jobs output? Isn't that a buildbot issue?04:24:26
@joerg:thalheim.ioMic92Yeah it's just bit weird how the last changes relate to that in any way. Do we have logs how nix-eval-jobs got called in that instance. 05:02:35
@zowoq:matrix.orgzowoq

Probably not the correct fix but this works:

Seems it was merging the output from the separate steps?
