@grahamc:nixos.org	speaking of which I'd really like to get rid of the scmdiff API thing	13:16:59
das_j	which one do you mean?	13:17:08
@grahamc:nixos.org	https://hydra.nixos.org/api/scmdiff?uri=https%3A%2F%2Fgithub.com%2FNixOS%2Fnixpkgs.git&branch=&rev2=0fd9ee1aa36ce865ad273f4f07fdc093adeb5c00&rev1=c68e3678f42352cc4f0ff42f48944c292eef1297&type=git	13:18:05
das_j	oh. why? we use this pretty often to see why builds could have failed	13:18:23
das_j	* oh. why? we use this pretty often to find root causes of build failures	13:18:38
@grahamc:nixos.org	I find it a bit frightening	13:18:52
@grahamc:nixos.org	allowing people to spawn processes that could be very expensive	13:19:08
das_j	oh it's spawning subprocesses? :/	13:19:21
@grahamc:nixos.org	the code is a thrill	13:19:31
@grahamc:nixos.org	it could be made much better if it took an evaluation ID & input name, and didn't leave the parameters to the diff to the user	13:22:17
das_j	ohh	13:22:34
das_j	I see your problem now	13:22:40
@grahamc:nixos.org	:)	13:22:51
das_j	Is the triggertime of a jobset also set when an eval was scheduled automatically?	14:06:02
das_j	Or to be more precise: Is this true? lastcheckedtime not set → no eval has been performed yet triggertime set → eval pending starttime set → eval running fetcherrormsg set → last eval failed during fetch errormsg set → last eval failed during eval	14:07:50
das_j	* Or to be more precise: Is this true? triggertime set → eval pending starttime set → eval running lastcheckedtime not set → no eval has been performed yet fetcherrormsg set → last eval failed during fetch errormsg set → last eval failed during eval	14:08:06
das_j	* Or to be more precise: Is this true? triggertime set → eval pending starttime set → eval running lastcheckedtime not set → no eval has been performed yet fetcherrormsg set → last eval failed during fetch errormsg set → last eval failed during eval if all the previous conditions failed → eval was successful	14:09:03
das_j	* Or to be more precise: Is this true? starttime set → eval running triggertime set → eval pending lastcheckedtime not set → no eval has been performed yet fetcherrormsg set → last eval failed during fetch errormsg set → last eval failed during eval if all the previous conditions failed → eval was successful	14:11:19
das_j	if these assumptions hold true, then my code now shows the status of the next evaluation in the jobsets overview:	14:25:25
das_j	Download image.png	14:25:26
@grahamc:nixos.org	oh cool	14:25:49
@grahamc:nixos.org	my brain is a bit overloaded this morning with toddler & infra things so not sure I Can follow that rigth now	14:26:08
das_j	Don't worry about it. I'll open a PR for it and pick the diff into our Hydra which should be enough for downstream testing it. You can press the magic button whenever you feel like it ;)	14:27:01
das_j	Download image.png	14:27:17
das_j	this also turns the yellow "Error" into emoji	14:27:24
@grahamc:nixos.org	:)	14:28:26
das_j	grahamc (he/him): re https://github.com/NixOS/hydra/commit/8c3c573953be97bcff103e9fec9e438c9bf3e3a7	17:03:58
das_j	have you encountered this error while evaluating?

@grahamc:nixos.org	:horror:	17:05:50
das_j	should I just… drop the constraint?	17:08:21
