Sending too many requests in a short time period can cause a crash

[avdstaaij]

Multiple users have reported that, when sending many requests in a short period of time (usually because buffering is turned off), GDPC can crash.

I cannot reproduce this bug on my own machine. I have tried running the code below, but it finishes without problems. If anyone else can reproduce this, I'd like to hear it!

from gdpc import Editor, Block
from gdpc.vector_tools import addY


def main():
    editor = Editor()

    buildArea = editor.getBuildArea()

    pos = addY(buildArea.toRect().center, 100)

    for _ in range(100_000):
        editor.placeBlock(pos, Block("minecraft:red_concrete"))
        editor.placeBlock(pos, Block("minecraft:blue_concrete"))


if __name__ == "__main__":
    main()
