NetworkMarker now contains a list of post listeners that are invoked
(in no particular order) when a packet has been serialize and sent
to a player, OR, when it has been enqueued for processing by the
server.
This works for both 1.7.2+ (Netty) and 1.6.4 and earlier, though the
1.6.4 version has a good deal more overhead.
If we update the number, we have to also use the "empty file" trick
to remove the old file, which will crash ProtocolLib on the first
reload. It takes a second reload for it to function at all.
It's much better to take the hit on the version number, and avoid
this issue altogether. The update method simply wasn't designed for
plugins with version numbers in their file name.
This was necessitated by two new NMS changes:
* NBTCompressedStreamTools.a(DataInput, int) now includes an additional
parameter NBTReadLimiter
* GameProfile changed the type of getId() from String to UUID, along
with the constructor (String, String) to (UUID, String).
We don't want to crash plugins over this, since it doesn't
automatically cause problems. But it may trip up plugins that
assume the packet types they set when registering a listener is the
only ones they'll ever recieve in the method body, which is not true
if a preceeding packet listener can change a packet to an arbitrary
type.
I'm open for better suggestions here. But for now, I'll just print a
warning and hope people use sendServerPacket() instead.
In 659f01cc63, I attempted to
execute packet listeners for receiveClientPacket() on the channel
thread, inadvertently causing them to be executed regardless if
filtered was FALSE, and twice if it is TRUE.
Since asynchronous packet listeners use this feature to take out
packets from the packet stream, they wound up causing an infinite
packet loop. This prevented them from ever being received by the
server.
An example of a dual side packet is Packet101CloseWindow, which is
sent by the server when it forces a inventory window to close, or
by the client to the server when the player voluntarily closes it.
The bug prevented the client-side of a dual side packet from being
recognized in 1.6.4. Thanks to Shevchikden for discovering the bug,
and finding the correct build number where it was introduced.
