Server message spam! #2

[Jammet]

Okay, someone must've done something, I have no idea what, and now, I'm seeing this all the time.

Help?

Hmm. Perhaps someone has a farmer villager down at bedrock.

[Jammet]

Is there some way I can find this? It doesn't say any coords. I've been down at the mine that player has and did not find anything.

However, he tried the new minecarts physics. He died below the bedrock and it seems down there he picked up items from players who died, previously, and then died again, or something. Really odd.

[xoft]

I created a PR that will log the detailed coords. There's not much else we can do for diagnostics right now. Try building from the PR branch (DetailedBlockAreaLogging), identify the problematic area a before you take care of it, could you please post the relevant part of the world, so that we can have a look at what's causing this.

[Jammet]

^^' I haven't the slightest clue what a PR is. I did try to build Cuberite right here on the pi with that "I'll do anything and you just watch" script a few times and that wasn't working then. Um.
I really appreciate what you do there, but unless it's kinda in the master, and I can just grab a binary from there, I'm probably going to be unable to test this. I'll gladly test and put time and effort into this, but my time is very limited these days. Gosh, sounds like a cheap excuse, but really, that's kinda difficult for me.

[NiLSPACE]

PR = Pull Request -> https://github.com/cuberite/cuberite/pull/2853

Try to build that branch. It will tell you where the spam is coming from. If you can tell us that we can fix it.

Do you use Windows? If so I can quickly build it for you.

[xoft]

@Jammet, how large is the world, would it be feasible for you to post a copy of it somewhere so we can test it ourselves? I guess with some luck we'll run into the right area that causes the spam.

@NiLSPACE: RasPi, not Windows. Nevertheless, I think we could merge the PR in anyway so that it's in master.

[Jammet]

The world is a few hundred megabytes, compressed, I believe. I can share that world with all of you, of course.
At this moment I already have a theory as to what is causing this. Someone was planting trees in an underground cave. Once I removed these trees and the greenery, those debug messages completely disappeared. Replanted those trees, the messages come right back.

It's always helpful if the server pinpoints to a problem if it can, so I'm all for having debug messages that show you where it hurts.

Thank you so much for helping! I should try and learn this building stuff at some point. Consider me to be some kind of "end user" who's invested but not able XD. If that makes sense. I just use the thing .

[Jammet]

Those messages are back again .... . I've been looking at those places and they seem absolutely fine to me. Help?

The problem lies in #3090, I'll fix it.
