(Darwin) strange error on .to_cuboid[]

Hi I'm AutoThreadBot! Don't mind me, I'll just be adding the helper team to this thread so they can see it. A human will get to you soon.

[lunar quiver]

you've been here long enough to know better than to make threads like this

you know what information we need

[bronze shuttle]

have no idea
what do you mean?

[lunar quiver]

How do you replicate this?

If i'm on a blank testing server, how could i trigger it?

[bronze shuttle]

It's just a random bug. I have no idea how to replicate it

It's worked fine all day and now just poof. And it's not

The only thing a can tell, samosbor is not a default world

  - createworld samosbor generate_structures:false worldtype:FLAT "settings:{"structures":{"structures":{}},"layers":[{"block":"minecraft:air","height":1}],"biome":"minecraft:samosbor_void","flat_world_options":{}}"

[lunar quiver]

It's just a random bug. I have no idea how to replicate it
then it's problem solving time. What does the error message say?

(it's literally what you copied above)

[bronze shuttle]

World unloaded?

[lunar quiver]

Is the world unloaded?

If so, does loading it fix the issue

[lunar quiver]

Does this problem occur with any other worlds or just this one?

[bronze shuttle]

https://paste.denizenscript.com/View/124132
just this

[lunar quiver]

Just that world? do other tags function fine on it?

what if you're standing in it?

[bronze shuttle]

I bet it will fix itself after restart
But it should be addressed, since it's a critical thing

[bronze shuttle]

as you can see in debug

[lunar quiver]

it's impossible to 'address' without having any consistent way to replicate

[bronze shuttle]

it doesn't matter when creating cuboid, but chunks are loaded

[lunar quiver]

everything has a cause

as in, it'll still through the error if you're in the world?

[bronze shuttle]

This happened after I made samosbor world not default
So I think it's partially unloaded somehow
Maybe after several destroy adjusts

[bronze shuttle]

yes

[bronze shuttle]

by happened I mean it worked even with non default world. but suddenly stopped after several uses

huh?
<location[-1,1,0,samosbor].to_cuboid[<location[-12,5,-11,samosbor]>]>
works fine

with
-1,1,0,samosbor -1,0,1,samosbor 0,0,0,samosbor
it's working

but with -1,0,0,samosbor it's not

how is this possible?

[bronze shuttle]

I restarted the server, and as I said, it's working now

[rocky urchin]

Well, there's very little we could do without a way to replicate the issue - did you create the world in the same server run you tried using that tag in maybe? and then after a restart it works fine?

[bronze shuttle]

I triggered it several times on a test server
but I still don't understand why this happens

Cuboidtag doesn't even require world to exist

[thin elbow]

[bronze shuttle]

Yeah. How world can be unloaded if it doesn't have to exist

[bronze shuttle]

You can see in my logs
I send in random order this commands
` - adjust <world[test]> destroy

• createworld test generator:denizen:void
• narrate <location[0,0,0,test].to_cuboid[<location[5,5,5,test]>]>`
  and error just suddenly appears sometimes. And sometimes does not

But if it appeared one time, this tag will be broken until /ex reload

[rocky urchin]

Is it specifically with to_cuboid? what if you just construct a location?

[bronze shuttle]

https://paste.denizenscript.com/View/124143

[bronze shuttle]

Steps to reproduce:

- createworld test generator:denizen:void
- narrate <location[0,0,0,test].to_cuboid[<location[5,5,5,test]>]>
if no error
- adjust <world[test]> destroy
repeat

More investigation:

When in bugged state
<location[1,1,1,test].to_cuboid[<location[5,5,5,test]>]> won't work
<location[1,1,1,test].to_cuboid[5,5,5,test]> will work

https://paste.denizenscript.com/View/124165

Also
<location[1,1,1,test].to_cuboid[<location[6,6,6,test]>]> works

I can't understand this bug. Is there is something wrong with Static Tag Processor?

[rocky urchin]

@sullen violet these errors seem to happen because the Bukkit Location has an empty reference to a world (but not null), I.e. it had a world instance that was GCed away? might be static tag processing caching a location instance that later loses it's world?

[sullen violet]

there's a whole dedicated system to catch and fix that

it looks like spigot actively fucked that system in an update at some point with an unloadedness check that will have to be aggressively bypassed now :(

[sullen violet]

should be fixed ref #commit-log
