@yujunz are you able to provide us with CUE code to reproduce this panic?

yujunz commented Oct 10, 2024

The CUE code it pretty complex with deep import chain. I can try to narrow down since cue eval -p path still works on specific paths.

Or shall I try evalv3 since it seems an evaluation error?

mvdan commented Oct 10, 2024

If you could try evalv3 that would also be helpful, yes. Although we would still like to fix any panics in evalv2.

CUE_EXPERIMENT=evalv3 cue eval doesn't panic but throws a bunch of errors.

  • 64 field not allowed
  • 2 cyclic reference to field
  • 1 incompatible list lengths (0 and 5)

It may take some time to narrow down the error, but do you have any quick hint which could be the root cause of panic in current version?

yujunz commented Oct 11, 2024

Could this be the culprit?

#App.base.alpha.#var.volumes."vault-token".mount.mountPath: cyclic reference to field "vault-token":
    ../../../../_base/kubernetes.cue:293:3
#App.base.alpha.#var.volumes."vault-token".volume.projected.sources: cyclic reference to field "vault-token":
    ../../../../_base/kubernetes.cue:293:3

from

#var: volumes: "vault-token": {
	volume: projected: sources: [{
		serviceAccountToken: {
			path:              _local.vault.tokenPath
		}
	}]
	mount: mountPath: _local.vault.mountPath
}
_local: vault: {
	mountPath:  "/var/run/secrets/vault/serviceaccount"
	tokenPath:  "token"
}

while it is tested OK in https://cuelang.org/play/?id=VXxtPsG0DAO#w=function&i=cue&f=eval&o=cue

The full configurations includes much more in #var and _local though.

Is the code public? If so, could you share a link? If not, would you be able to share it with us privately so that we can reproduce the crash, as well as all the evalv3 issues to be fixed?

Unfortunately not. It's a huge private mono repo. I'll try to narrow down to a sharable subset to reproduce and share.

I'm able to narrow down it a bit to one type of error field not allowed with evalv3 and panic without evalv3 now. See screenshot of error context.

See also https://gist.github.com/yujunz/310b4e462432b63faf9c4ce1dca06534 for the related part of alpha.cue. It is a nested loop with if condition. I can't share app.cue for now but will try to tailer down to a reproducible set.

Please let us know when you do find a smaller reproducer you can share with us. Because ideally we want bug fixes to be paired with a regression test. Plus, a reproducer is also useful to debug what's going wrong.
