Process loads outside of any canSleep check. Original intent was to only apply those restrictions to generations but realized I had some checks higher up the call chain. Reworked the back off strategy to just run every 1 millisecond per world, and to apply the per tick limit to generations only. This guarantees that your chunk will load with at most around 1ms delay. Additionally, fire midTick processing in a few more places, notably the oversleep section so we can keep processing loads here too which has a large up to 50ms window... Speaking of oversleep, we had a bug in our implementation changes for Timings that caused oversleep to not sleep the correct amount. Because we now moved it into the NEXT tick instead of THIS tick, the value of nextTick had already been increased to +50ms, resulting in the risk of sleeping more than it should, but, more importantly, this caused every task that was trying to NOT run during oversleep to actually run during oversleep. This is now fixed. Another small tweak is to the /tps command, to no longer show the star when TPS is right at 20. Due to ineffeciencies in the sleep precision, TPS is commonly 20.02. This causes the star to show up almost constantly, so now only show it if we actually hit a real "catchup". This commit also improves the changes to the CallbackExecutor, in that it now is also recursion safe. It was possible that the executor could run tasks out of desired order if the executor task scheduled more executor tasks. We solve this by ensuring new additions do not enter the currently iterated queue. Each depth level will have its own queue. Fixes #3220

Subject: [PATCH] Optimize Hoppers
|
|
|
|
* Removes unnecessary extra calls to .update() that are very expensive
|
|
* Lots of itemstack cloning removed. Only clone if the item is actually moved
|
|
* Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items.
|
|
However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on.
|
|
* Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory
|
|
* Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration
|
|
* Don't check for Entities with Inventories if the block above us is also occluding (not just Inventoried)
|
|
* Remove Streams from Item Suck In and restore restore 1.12 AABB checks which is simpler and no voxel allocations (was doing TWO Item Suck ins)
