getOfflinePlayerData() will now return NULL if there is no stored data for a given player. The responsibility of checking the spawn point is now delegated to the Player, after it registers a chunk loader on its spawn chunk.
This prevents plugins sending wrong packets at the compiler level (or would, if we had a compiler). It's more robust than a getter for client/server and throwing an exception since a static analysis tool can detect faults created by sending wrong packets from the server. This is also used to deny service to dodgy clients which send wrong packets to the server to attack it.
this is in preparation for clientbound/serverbound packet separation. I did this already on another branch, but the changeset was dependent on a massive refactor to split apart packets and binarystream which i'm still not fully happy with.
This is a bolt-on feature that can't be disabled and causes serious grief for Unix server users, because it prevents ctrl+c aborting the server the normal way.
Instead, we prefer introducing a plugin to implement this functionality, so that users can opt-in or opt-out.
future enhancements:
- make gamemode an object containing information about abilities that players have in this gamemode (gamemodes are just predefined ability sets)
- get the magic numbers out of the API
This contains all of the static stuff that was previously embedded in the Entity static root. This solves a bunch of problems like circular dependencies between parent and child classes, encapsulating logic and reducing the size of the enormous Entity.php.
it's much less expensive to just calculate the modulo of the current tick and 20, and overwrite past entries. The effect is the same. The only difference is that the arrays won't be ordered by time, but that doesn't matter anyway.
This is better for performance because these then don't need to be reevaluated every time they are called.
When encountering an unqualified function or constant reference, PHP will first try to locate a symbol in the current namespace by that name, and then fall back to the global namespace.
This short-circuits the check, which has substantial performance effects in some cases - in particular, ord(), chr() and strlen() show ~1500x faster calls when they are fully qualified.
However, this doesn't mean that PM is getting a massive amount faster. In real world terms, this translates to about 10-15% performance improvement.
But before anyone gets excited, you should know that the CodeOptimizer in the PreProcessor repo has been applying fully-qualified symbol optimizations to Jenkins builds for years, which is one of the reasons why Jenkins builds have better performance than home-built or source installations.
We're choosing to do this for the sake of future SafePHP integration and also to be able to get rid of the buggy CodeOptimizer, so that phar and source are more consistent.
