this is perfectly fine to use, and preferable to getting a cyclic ref to the scheduler. TaskScheduler->cancelTask() does pretty much the exact same thing, and the scheduler internals are designed to deal with this anyway.
This greatly improves GC performance by being more intelligent about how it collects garbage tasks. It knows that if X task in the queue is not finished, none of the tasks behind it can be finished either, so there's no point checking them.
This also presents the opportunity to cleanup a lot of async pool internals, so I've taken it and torched a lot of garbage.
This is now self-maintaining and doesn't rely on the async pool to wipe its ass on task completion. Instead, the garbage collector will cause thread-local data to be automatically released when the async task is garbage-collected on the main thread.
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 Since this has now been superseded by storeLocal(), it doesn't make sense for this parameter to exist anymore.
- Added `Internet::getIP()`, `Internet::getURL()`, `Internet::postURL()`, and `Internet::simpleCurl()`.
- Deprecated the corresponding functions in `Utils`. Updating to the new functions is as simple as replacing `Utils` with `Internet`, since this doesn't break backwards compatibility.
The deprecations should be catered for by plugin developers. These deprecated redirects will be removed no later than 4.0.0.
they got removed from the tasks array, but not from the queue (for performance reasons). The queue gets cleaned up by the heartbeat, but it was checking if there were things in the main array, not in the queue.
There are a couple of other bugs with cancelling tasks that this doesn't fix that are rather more complicated to deal with.
This changes how the AsyncPool works so that it does not immediately always start all of the workers in the pool.
Instead, workers will be started only when an idle worker was not found.
This allows for significant memory footprint reductions while idle.
In effect the async-workers setting in pocketmine.yml now dictates a _maximum_ pool size, not a fixed pool size.
