Recursive

[d mg]

hi everybody,

My hammerspoon configuration is identical between my laptop and my desktop.

yet, my laptop keeps generating this errors:

2023-10-17 11:50:19: 11:50:19 ERROR:   LuaSkin: hs.ipc callback is being called recursively. Check your callback function, it is triggering further IPC messages. This message was triggered after reaching 5 recursive callbacks.

(several ones) and then

2023-10-17 12:21:55: 12:21:55 ** Warning:   wfilter: loginwindow (0) is STILL not registered

Given the timing, it is related to suspend (recursive calls)/resume (login window).

Does anybody have any idea where to look for the potential culprit? Is there a way to  add a backtrace in the error messages?

thank you for any hints,

--daniel

Hey

What do you have in your hs.ipc callback?

Cheers,

Hi Chris,

sorry for not replying before. I have been debugging this issue. I found and
removed a spoon that was creating most of the problems.

But there is some errors that happen after suspend/resume, But I have
not been able to pin-point why.

They seem to be happening when the computer is sleeping. I believe macos
wakes-up during suspend for few seconds.

2023-12-31 21:16:33: 21:16:33 ERROR: LuaSkin: hs.ipc callback is

being called recursively. Check your callback function, it is triggering further IPC messages. This message was triggered after reaching 5 recursive callbacks.

2023-12-31 22:00:02: 22:00:02 ERROR: LuaSkin: hs.ipc callback is being called recursively. Check your callback function, it is triggering further IPC messages. This message was triggered after reaching 5 recursive callbacks.

I am also getting this error:

2023-12-31 15:51:11: 15:51:11 ERROR: LuaSkin: hs.ipc:callback - error during callback for Hammerspoon: ...Hammerspoon.app/Contents/Resources/extensions/hs/ipc.lua:420: attempt to index a nil value (local 'fnEnv')


I have a hunch. Could it be that I turn off bluetooth just before going to
sleep, and enable it back when waking up. I have a callback to monitor
usb.

And for anybody looking for ways to debug strange errors, I found
that it is possible to change the level of messages to the console using hs.logger

hs.logger.setModulesLogLevel(3)
hs.logger.setGlobalLogLevel(3)



thanks again, Chris, for all the work you have done with hammerspoon

(and happy new year).
