Removes synchronization from sending packets
Makes normal packet sends no longer need to be wrapped and queued like it use to work.
Adds more packet queue immunities on top of keep alive to let the following scenarios go out
without delay:
- Keep Alive
- Chat
- Kick
- All of the packets during the Player Joined World event
Hoping that latter one helps join timeout issues more too for slow connections.
Removes processing packet queue off of main thread
- for the few cases where it is allowed, order is not necessary nor
should it even be happening concurrently in first place (handshaking/login/status)
Ensures packets sent asynchronously are dispatched on main thread
This helps ensure safety for ProtocolLib as packet listeners
are commonly accessing world state. This will allow you to schedule
a packet to be sent async, but itll be dispatched sync for packet
listeners to process.
This should solve some deadlock risks
This may provide a decent performance improvement because thread synchronization incurs a cache reset
so by avoiding ever entering a synchronized block, we get to avoid that, and packet sending is a really
hot activity.
If a sync load was triggered, it would process pending join events,
causing them to be added to the world in the middle of the entity ticking
process.
This caused their add to be queued instead of immediate, causing
"Illegal Tracking" errors.
This schedules it to fire at the players next Connection Tick, which
is exactly where this entire process use to run anyways.
Also added missing tab complete and syntax for syncloadinfo debug command
This change lets players who are in their bed have a position which is above
ground for a longer period of time. This is because of the server not setting
their position to the ground/exit location when entering the bed, resulting in
the server believing they're still in the air.
