k9s crash on m1 with index out of range [0] with length 0. #1654

samueltorres · 2022-07-12T10:00:23Z

Describe the bug
On Mac M1, sometimes k9s just crashes:

❯ k9s
 ____  __.________
|    |/ _/   __   \______
|      < \____    /  ___/
|    |  \   /    /\___ \
|____|__ \ /____//____  >
        \/            \/

Boom!! runtime error: index out of range [0] with length 0.

I've pulled the logs and that seems tied to the tview package.

@samueltorres Thank you for reporting this Samuel. Not sure I've got it so please checkout v0.26.0 and let us know if we're happier as I don't have an m1 on hand??

samueltorres · 2022-07-18T15:47:37Z

Thanks, I'll let you know.
Thank you for this great product :) Can't live with it ❤️

samueltorres · 2022-07-25T10:29:04Z

Unfortunately it continues to happen randomly :(

derailed · 2022-08-01T21:22:11Z

@samueltorres Hum... Bummer ;( If you can add some repro steps here when it happens we might be able to zero in. Tx!!

stevo-f3 · 2022-08-09T08:06:31Z

It happens on linux too, reproduced with v0.25.18. Will update to latest and see if it can be reproduced.

Btw this issue is listed as fixed in 0.26.0 for some reason.

azarudeena · 2022-08-31T09:19:51Z

running v0.26.3 version in M1 no issues for me

NickLarsenNZ · 2022-09-07T19:24:12Z

This has happened to me (v0.25.18), and I can't reproduce it. It occurred when I was filtering logs by typing /cid:11. I have run the same filter and it works fine.

I'm not using an M1.

EladDolev · 2022-09-26T10:48:24Z

happens to me to a few times a day
I don't remember it happened with v0.25.18 but it occurs on all versions v0.25.19 and later

I was opening a ticket about that but it looks like I got the same:

k9s version does not give much information 😬 sorry about that (maybe I built it myself? I don't remember)

thank you for the great tool anyway.

derailed · 2023-12-08T14:37:30Z

@emilienkofman Not sure which version of k9s you are running ??? Doesn't look like the latest
Anyway... If you can add a repro that would be super. Tx!

emilienkofman · 2023-12-08T15:27:24Z

Unfortunately I have no specific scenario since this also happens from time to time... if I found a more specific case I'll let you know.

fsologureng · 2023-12-13T12:34:50Z

Same here. k9s started showing a previous view which was a describe of a pvc, then I switched to :pods and it crashed.
Version 0.29.1.

derailed · 2024-01-12T22:05:15Z

I think this can be closed as of v0.31.5
