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.

Subject: [PATCH] Be more tolerant of invalid attributes
|
|
|
|
Prior to this commit, the player would be disconnected if they ever encountered an attribute with a name that did
|
|
not match Bukkit's expected vanilla scheme. It appears that datapacks can set whatever attribute name they want,
|
|
ignoring vanilla's typical scheme.
|
|
|
|
In a more perfect world the API would expose some way to interact with these attributes, however Bukkit is not
|
|
particularly flexible in this area. Perhaps this is an area for future expansion at a later time.
