this is a partial fix for #2717, but still not ideal because it'll spam whenever a chunk is attempted to be generated. However, fixing this properly requires potentially breaking API changes.
this now has a mouthful of a name. I'd like to invert it, but I can't do that without silently breaking backwards compatibility, which is unacceptable.
generating 1 large bounded random costs the same as generating 4 small ones, so it makes more sense to do it like this instead.
Note that prior to 7.1 this code would not work due to it not handling 64-bit appropriately.
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 doesn't fix shit but it at least doesn't crash. Fixing this properly can't be effectively done any other way without backwards compatibility breaks. Fortunately it's not common practice to grow trees at the top of the world.
This supersedes addChunkPacket() in most cases, and has a more clear name. It broadcasts the given packet to every player who has the target position within their chunk load radius.
Grass can cause issues here by requesting blocks randomly offset away from itself, which can cause silent chunk loading on chunk ticking. It also causes crashes if chunk autoloading is taken away, which is obviously undesired.
It was also noticed that player chunkloaders cause chunks to start getting ticked as soon as they load their first chunk, which is before the entity is visible to everyone else on the server. This is probably undesired behaviour.
This has the triple bonus effect of a) making a lot of code easier to read, b) reducing Server::getInstance() usages, and c) removing a whole bunch of Server dependencies.
The network and block namespaces are untouched by this commit due to potential for merge conflicts. These should be dealt with separately on master.
