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
We still keep vanilla process of waiting for existing session to be removed before logging in
by storing a separate map of pending.
also fire the callback using executor incase further recursion causes any trouble
Bump chunk priority to ensure chunks load fast
Handle case where client disconnects before they even fire PlayerJoinEvent
- no longer call PlayerQuitEvent or print quit message.
- don't save the player data file if never joined. Nothing has changed.
CraftBukkit has a bug here that if you do save it, you will lose
any horse that the player logged off on because the horse hasn't
been resummoned yet.
No longer will trigger Synchronous Chunk Loads when a player logs
in to the server.
Will delay PlayerJoinEvent until the chunk has been loaded.
Should have massive performance benefits for larger servers with
lots of players logging in and out.
