Signal 11 Error #109

Closed realsurya closed 2 years ago

realsurya commented 2 years ago

Hey devs,

I was just trying out newwn and it seems very cool and interesting. However, I get intermittent crashing due "Error: Signal 11" similar to #106. I'm usually able to use the compositor for a couple minutes before it crashes due to error 11.

Not sure if you actually got the logfile from #106, so I've attached a logfile here for reference. Hope this helps!

Thanks for the log!

Can you see any patterns? I.e. does it crash when you close a window, or something similar?

realsurya commented 2 years ago

Yep there seems to be a very peculiar pattern. I did a few tests today:

1) Starting newm and doing nothing. 2) Starting newm and opening a single terminal (Alacritty) and using HTOP. 3) Starting newm and opening terminal & Firefox.

On all three trials, newm took 1 min 16 seconds to crash to error 11, which is interesting. I've attached all three logfiles just in case you're interested, since it's bizarre the timing seems so consistent.

My machine specs are:

newm_log_Firefox.txt newm_log_OnlyUsingHTOP.txt newm_log_WhenDoingNothing.txt

Thanks a lot, that helps.

I haven't yet been able to reproduce, but the logs and you're patterns suggest it might have to do something with the panels (which are started automatically in the background when they finish). Somehow starting the launcher panel fails and the interaction between the panel starting and the compositor triggers the bug (segfault).

To verify this thought - can you try disabling the panels and post a log?

panels = {
   `launcher`: { `cmd`: None },
   `lock`: { `cmd`: None }
}

Also, can you check for ~/.cache/newm_panel_log and post it?

Im finally able to reproduce! :) happens for me only when encourage_csd is set

This should be fixed by https://github.com/jbuchermn/pywm/commit/7980012191e953440eca87e168c81d8185344c39
