Spigot still maintains some partial implementation of "tick skipping", a practice in which the MinecraftServer.currentTick field is updated not by an increment of one per actual tick, but instead set to System.currentTimeMillis() / 50. This behaviour means that the tracked tick may "skip" a tick value in case a previous tick took more than the expected 50ms. To compensate for this in important paths, spigot/craftbukkit implements "wall-time". Instead of incrementing/decrementing ticks on block entities/entities by one for each call to their tick() method, they instead increment/decrement important values, like an ItemEntity's age or pickupDelay, by the difference of `currentTick - lastTick`, where `lastTick` is the value of `currentTick` during the last tick() call. These "fixes" however do not play nicely with minecraft's simulation distance as entities/block entities implementing the above behaviour would "catch up" their values when moving from a non-ticking chunk to a ticking one as their `lastTick` value remains stuck on the last tick in a ticking chunk and hence lead to a large "catch up" once ticked again. Paper completely removes the "tick skipping" behaviour (See patch "Further-improve-server-tick-loop"), making the above precautions completely unnecessary, which also rids paper of the previous described incompatibility with non-ticking chunks.

Subject: [PATCH] Improve and expand AsyncCatcher
|
|
|
|
Log when the async catcher is tripped
|
|
The chunk system can swallow the exception given it's all
|
|
built with completablefuture, so ensure it is at least printed.
|
|
|
|
Add/move several async catchers
|
|
|
|
Async catch modifications to critical entity state
|
|
These used to be here from Spigot, but were dropped with 1.17.
|
|
Now in 1.17, this state is _even more_ critical than it was before,
|
|
so these must exist to catch stupid plugins.
|
