[ST Edge] Issues with the call_with_delay function

Developer Programs Writing Edge Drivers

Here’s a new one I haven’t seen reported yet:

I have a driver using a 3 second call_with_delay and my function is being executed twice in rapid succession:

driver:call_with_delay(3, clearmsg)

local function clearmsg ()

  webreqDriver:get_devices()[1]:emit_event(cap_select.selection(' '))
  
end

Follow up to my post above. I think this is related to a previous problem I have come across where I start getting duplicate execution of routines in drivers. It hasn’t happened in a couple weeks, but it started again last night, with the first thing I noticed resulted in the post above. But subsequent to that I started seeing duplicate behavior across multiple drivers: for example, creating one device, but getting two. Sending one LAN message once, but it getting sent twice. I find that re-booting the hub is necessary to stop the duplicates. And that is what I’ve done this morning, and the problem has cleared up, including the one i reported above.

Hi, @TAustin. I haven’t been able to replicate the behavior you mention, since the last reboot, has it happened again?

Once I rebooted my hub this morning it has not happened since.

It seems that this duplication issue gets triggered typically as a result of a lot of driver deletes, adds, and updates when I’m in a fast and furious iterative development phase. Something on the hub gets messed up. But at least I know the cure!

I see, do you execute the commands to do this (delete, package, etc.) with a script or manually?

A combination of CLI command scripts and individual CLI commands.
