@roberthensing:matrix.orgRobert Hensing (roberth)* a rebase would help reviewers I think12:12:07

@jonge:ukvly.orgjonge hey friends, i created a PR that syncs the docstrings of the Machine class's methods and the nixos docs of the test driver. if anybody would be interested to look at this this would be a great help: https://github.com/NixOS/nixpkgs/pull/242135 10:09:27
@raitobezarius:matrix.orgraitobezariusWill take a look when I can :-)10:53:52
@raitobezarius:matrix.orgraitobezariusThank you!10:53:55

@nikstur:matrix.orgnikstur joined the room.14:29:36
@nikstur:matrix.orgnikstur Is there any simple way I can wait for a machine to reboot? I want to test a service that automatically reboots the machine on success (as unitConfig.SuccessAction = "reboot"; so the reboot is not initiated by the test itself 14:31:18
@nikstur:matrix.orgniksturI'll even take a complex way because I can't figure it out :D14:43:53
@raitobezarius:matrix.orgraitobezariuswait_for_unit("$unit.service") ? :p14:44:13
@raitobezarius:matrix.orgraitobezariusafter a machine.crash() ?14:44:21
@nikstur:matrix.orgniksturWorks only if I trigger the crash from within the test. But the service running in the VM triggers the reboot15:01:01
@raitobezarius:matrix.orgraitobezariushmm15:01:12
@raitobezarius:matrix.orgraitobezariusso you want something to say "now you are rebooting"15:01:22
@nikstur:matrix.orgniksturAnd waiting for reboot.target etc doesnt work either15:01:27
@raitobezarius:matrix.orgraitobezariusour protocol to assert the state of the machine is suboptimal for that15:01:43
@nikstur:matrix.orgniksturwait_for_reboot() or something15:01:44
@raitobezarius:matrix.orgraitobezariusI think you need to do adjustments for that15:01:49
@raitobezarius:matrix.orgraitobezariusin the internal state machine15:01:53
@nikstur:matrix.orgniksturHad hoped, I wouldn't need to touch it15:06:43
@nikstur:matrix.orgniksturmhhhm15:06:49
@nikstur:matrix.orgnikstur Ok so one thing I figured out is that I need to set machine.connected = False so that it reconnects to the shell 15:12:23
@nikstur:matrix.orgnikstur Now I can machine.sleep but thats obv not a very robus solution 15:12:50
@raitobezarius:matrix.orgraitobezariusThere was discussion in NixOS Systemd about RIIR the protocol between VM and driver15:16:52
@raitobezarius:matrix.orgraitobezariusso it would have proper framing, et.15:16:56
@raitobezarius:matrix.orgraitobezarius * so it would have proper framing, etc.15:16:58
@nikstur:matrix.orgniksturI read that thread but I don't think this would really improve the situation for waiting for a reboot 15:56:05

@raitobezarius:matrix.orgraitobezarius nikstur: I think something is very wrong with our NixOS tests wrt to boot 21:42:34
@raitobezarius:matrix.orgraitobezariusAnd reason for why it's breaking also Lanzaboote tests21:42:42
@raitobezarius:matrix.orgraitobezariusbut I feel like this is driver specific21:43:20
