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 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.
This brings two plugin-breaking changes: AsyncTask->onCompletion() and AsyncTask->onProgressUpdate() no longer accept Server parameters.
This now allows for the functionality of AsyncPool and AsyncTask to be tested outside of a Server.
This is a leftover from when it was necessary to pass complex data to the AsyncTask constructor in order to have it locally-stored. Since this has now been superseded by storeLocal(), it doesn't make sense for this parameter to exist anymore.
This has long been a waste of time and creativity, and that's only going to continue to be the case now that we're going to be properly versioning. New codenames every couple of months is not worth the bother.
This commit contains quite a few breaking changes with respect to how AsyncTasks are handled. This is necessary to allow separation of the ServerScheduler and the AsyncPool, because in the future the ServerScheduler may be removed and instead there will be isolated per-plugin sync-task schedulers - but we cannot have every plugin with its own worker pool for memory usage reasons if nothing else.
The following things have changed:
- ServerScheduler: scheduleAsyncTask(), scheduleAsyncTaskToWorker(), getAsyncTaskPoolSize(), increaseAsyncTaskPoolSize() and similar methods have all been removed. Additionally the static \$WORKERS field has been removed.
- Server: added API method getAsyncPool(). This grants you direct access to the server's AsyncPool. Calls to getScheduler()->scheduleAsyncTask() and scheduleAsyncTaskToWorker() should be replaced with getAsyncPool()->submitTask() and submitTaskToWorker() respectively.
this implementation was god-awful bad and it was entirely avoidable to make it this complicated.
This utilizes the fact that pthreads treats static properties as thread-local. AsyncTask local storage now utilizes a \SplObjectStorage stored in an AsyncTask private static field.
this needs further changes (particularly to Furnace) to stop things abusing NBT for runtime data handling, otherwise performance is going to drop off a cliff.
