This allows other threads to notify the main thread to wake it up while it's sleeping between ticks, allowing reduction of processing latency.
Currently only RakLib and the CommandReader threads utilize this, but it's planned to extend it to more things in the near future.
CommandReader is now event-driven instead of poll-based - the server will not poll the CommandReader thread for messages each tick anymore.
RakLib utilizes this mechanism to get packets processed without delays to lower latency.
This now adds an extra dependency - `pocketmine/snooze` library contains the meat of the code used for this. See the Snooze repository for details.
Use stream_select to poll stdin status before reading
Add detection for FIFO pipes, rewrite half of the CommandReader (again)
Add timeout for CommandReader to prevent hang in Windows custom consoles (unknown reason)
All plugins will need to bump the API if they want to use this.
NOTE THAT THIS IS NOT THE FINAL API 2.0.0 AND THAT THERE WILL BE MORE CHANGES.
To start updating, you might also want to read https://secure.php.net/manual/en/migration70.php and specifically https://secure.php.net/manual/en/migration70.incompatible.php
To compile PHP7 with some of the required dependencies, use https://gist.github.com/shoghicp/166ab26ce5cc7a390f45
ONLY LINUX IS TESTED, DO NOT ASK FOR OTHER PLATFORMS!
----- THIS VERSION IS NOT SUPPORTED -----
This version WILL crash randomly in unexpected places due to PHP7, pthreads, PocketMine or cosmic rays.
Handle with care, and store under direct sunlight for the best performance.
