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] Fix CraftServer#isPrimaryThread and MinecraftServer
|
|
isMainThread
|
|
|
|
md_5 changed it so he could shut down the server asynchronously
|
|
from watchdog, although we have patches that prevent that type
|
|
of behavior for this exact reason.
|
|
|
|
md_5 also placed code in PlayerConnectionUtils that would have
|
|
solved https://bugs.mojang.com/browse/MC-142590, making the change
|
|
to MinecraftServer#isMainThread irrelevant.
|
|
By reverting his change to MinecraftServer#isMainThread packet
|
|
handling that should have been handled synchronously will be handled
|
|
synchronously when the server gets shut down.
