Description of the bug

When the listener script outputs a line, eww logs shows: "Scope not in graph"

I went through the code and changed the error so that I could see the Scope index that couldn't be found, and noticed that the values continually get bigger and bigger.

The above statement isn't the issue, I just thought it would be relevant and was trying to do some debugging on my own.

The error leads me to believe that there are hanging references somewhere.

Sorry for not being able to provide more information

Reproducing the issue

Minimal config:

eww.yuck

(deflisten bspwm-state
  :initial `{"desktops":[]}`
  "./desktops")

(defwindow bar
  :geometry (geometry :anchor 'center left')
  :windowtype 'dock'
  (desktops))

(defwidget desktops []
  (box :orientation 'v'
    (for desktop in { bspwm-state.desktops}
      (desktop-label :desktop {desktop}))))

(defwidget desktop-label [desktop]
  {bspwm-state.focusedDesktopId == desktop.id ? 'Y' : 'N'})

./desktops:

#!/usr/bin/env bash

bspc query -T --monitor
bspc subscribe desktop | while read
do
    bspc query -T --monitor
done

Expected behaviour

There shouldn't be an error as far as I'm aware, the listeners should stop before the widget updates and the notify is sent.

Additional context

The bspc query -T --monitor outputs with the following format:

{
  "focusedDesktopId": <ID as number>,
  "desktops": [
    { "id": <ID as number> },
    ....
  ]
}

Full output

There are a bunch of omitted fields, so here's a full example output:

I ran into a similar issue. I believe it has to do with iterating over arrays that are contained in listened-for objects. When I isolated the array from the object, only printing the array to the listener raw, the errors stopped.

bumping this, this might be closed by #1189. feel free to test things out and report your findings there! update: the pr doesn't fix this. i'll investigate this if i find the time to do so

w-lfchen commented 1 month ago

found the problem: seems like something is not updated properly and the variable wants to access old listeners sometimes that have been removed already.

i'll see whether i can fix it, it's always this error

update: this is weird, according to my debug prints, the scope is removed after the error states that it's not in the graph. i'll have to investigate further

update 2: seems like a tokio select race condition of some kind

here's my debugging config:

(defpoll obj
  :interval "1s"
  :initial `{"i": 3, "arr":[0]}`
"echo {\\\"i\\\": 3,\\\"arr\\\": [0]}")

(defwindow broken
  :monitor 0
  (widg))

(defwidget widg []
  (box
    (for desktop in {obj.arr}
      (widg-label))))

(defwidget widg-label []
{obj.i})

funnily enough, the whole widget disappears if the initial array is left empty. that's probably a different edge case bug
