@vcunat:matrix.orgVladimír Čunát I'm not fond of making nixos-unstable dependent on darwin builds. 11:56:45
@emilazy:matrix.orgemilyregardless of success/fail blocking, because of the infra capacity problems? I know there's been issues with -next recently, has it held back nixpkgs-unstable bumps though?11:58:04
@vcunat:matrix.orgVladimír ČunátI could certainly come with some scenarios, e.g. some security rebuilds do get way more expensive for darwin than linux.11:58:06
@emilazy:matrix.orgemilythose should be conditionalized anyway right?11:58:35
@emilazy:matrix.orgemilybecause nixpkgs-unstable is used on Linux too11:58:42
@emilazy:matrix.orgemilye.g. by all users on other distros by default11:58:50
@emilazy:matrix.orgemilyso status quo doesn't change there11:59:06
@vcunat:matrix.orgVladimír ČunátFlakes also default to nixpkgs-unstable, IIRC.11:59:17
@emilazy:matrix.orgemilyyeah, and the channel in the installers I believe11:59:36
@vcunat:matrix.orgVladimír ČunátBut users can easily override this. Verification of blocker NixOS tests does have benefits.12:09:30
@emilazy:matrix.orgemily right. well I was thinking nixpkgs-unstable should probably just gate on those too 12:19:58
@emilazy:matrix.orgemilyI don't see much reason not to since they get fixed reasonably promptly for obvious reasons12:20:20
@vcunat:matrix.orgVladimír Čunát So no difference between nixos-unstable and nixpkgs-unstable then? 12:25:27
@vcunat:matrix.orgVladimír Čunát(same for the stable pair which is differently split, confusingly)12:25:57
@vcunat:matrix.orgVladimír ČunátThere's some risk from this jobset getting significantly bigger than either. As it is now, performing an eval can stall progress of builds for about 20 minutes, apparently because of dependencies between postgresql transactions. (doing an eval as one huge transaction is tough)12:32:30
@vcunat:matrix.orgVladimír ČunátBut maybe the reduction in overall job count (summed together over jobsets) would even help this aspect.12:33:21
@vcunat:matrix.orgVladimír Čunát* There's some risk from the merged jobset getting significantly bigger than either. As it is now, performing an eval can stall progress of builds for about 20 minutes, apparently because of dependencies between postgresql transactions. (doing an eval as one huge transaction is tough)12:33:43
@emilazy:matrix.orgemilywell, latter would block on Darwin as now12:35:12
@emilazy:matrix.orgemilybut right, no difference for Linux specifically12:35:26
@vcunat:matrix.orgVladimír ČunátLooks good: https://hydra.nixos.org/build/325215479#tabs-constituents13:15:41
