Server dies when I try to use box to fill a 80x80x80 volume with air
This kills a server running on our raspberry pi:
/js box(blocks.air, 80, 80, 80);
On my pc, running windows 10, the command succeeds after some laggy seconds. The question is if scripcraft creates a huge todo array with all positions that should be setblock:ed. If it does, then it is unnecessarily memory consuming and should be redesigned (if possible).
The log on the raspberry pi, after it has died is in hs_err_pid8060.log:
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 236040192 bytes for committing reserved memory.
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.

half a million blocks is a lot...

Obviously if it's above 1.7.10 it wouldn't work because it's outdated.

Yeah I didn't read it updated to 1.11.2 yes half a million is big be nice to write to block updated directly. But spigot doesn't allow that. Nor does bukkit.
This the way it was coded. Best way to describe it @AndersBillLinden Spigot likes to use redirects so does bukkit here is my example... (regarding that they may have a different opinion.) Spigot/Bukkit uses there own method to tie a threshold with any event handler they want, while also pumping up memory. (example CoreProtect is a good reason why this happens) It would be nice if they added a method to write to blocks directly (packet wise) to make things faster.
What is redirected? Is there an event queue of some kind that fills up? Do you know where I can find the source that causes the problem?
@AndersBillLinden Spigot is semi-closed source. It fills up the event for block creation. Packets would be faster in this case. Give me a while and ill try to get a example for you from the code. (like 2 days max). Your answer to what is redirected it Spigot/Bukkit/Etc way of making thing easier for you coding wise.
EDIT: It's not just packets also.
@AndersBillLinden Ill see if I can't make an addon (for ScriptCraft) for this. I will call the world generator directly.
Should this be labelled as an Enhancement request to include better support for large arrays of blocks? Or is this still considered a bug in that there are limits?
As you guys discussed, there are some lower-level limits and it will take some refactoring to accommodate. Instinctively I'm thinking that any platform will fall over if enough gets thrown at it. The general resolution is to packetize and modularize to reduce the load on the resources. Personally I think we could all benefit better from a well-written paper that explains the problem here and offers a procedural solution for other developers. Thoughts?
to be fair, asking a raspberry pi to generate an 80x80x80 box in a minecraft server is like asking a desk calculator to run windows
the server is pretty crappy and inefficient about it, and i don't think this is within scriptcraft's scope (unless there are bulk apis that scriptcraft isn't taking advantage of)
if @djlw78 creates a plugin that makes block management faster in spigot, then this could become an enhancement request to take advantage of it if the plugin's loaded in
Its not the speed that is the problem, but it seems like the algorithm uses memory it should not use. Like it was creating a list with all blocks that should be output or something. (I have not checked how it is built up).
Now that I'm into the code I need to spend some time to get an in-depth understanding of how these features work. It will take some time but it'll happen. @SEAPUNK, you're right that there is a "reasonable" limit. @AndersBillLinden thanks for the insight - right or wrong it helps to have some idea about what to look at.
FWIW, my server chokes and dies at box(blocks.anything,70,70,70). I've tried increasing memory to the JVM but that's a science in its own right, and nothing I do there seems to help much anyway. It'll take some time to work through an algorithm that allows for pauses, memory releases, breaking builds like this into segments ... or whatever it will take to keep it from falling over.
There is a variable which controls the maximum number of blocks that a drone will process. The default has been 1 million. We're seeing that this is too optimistic for some servers. To avoid a server crash, in v3.2.2.8 Beta, the limit has been reduced to 216000, which is the volume of a 60x60x60 cube. This can be changed in the source. (That link will get invalidated as the code is updated but this is probably going to change in v4 anyway.)
Is that a reasonable temporary solution?
BTW, I haven't tried it yet but look in the docs for "cuboid" and let's see if using cuboida() or a similar function has the same issue as box().
Why is there a maximum number of blocks that a drone will process?
Well, that's the big question that needs some investigation. I haven't looked deep into it but apparently it just queues-up everything it needs to do, without something like a FIFO pipe to buffer how much gets in the queue. So the limit that's built-in just says "throw an error if there are too many blocks". I've reduced that subjective "too many" from 1 million to 216 thousand ... temporarily.
The real effort will be to find out how it works and what can be done about handling the bulk. Maybe it first generates all required objects and then places them? I dunno. That could be put into a loop to do building with a limited set of blocks, like multiple commands executed one right after another. But remember that a Drone passes an instance of itself to the next function. It's possible that any given request could bloat the drone, so that it's not one request for a box of 80x80x80 that blows it up, but even a number of requests for 40x40x40.
The solution will be in getting the drone to do a small amount at a time, and to forget about whatever it's done when it's no longer required (probably by releasing objects to garbage collection).
