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 breaks down the handling of tile creation even further.
- Introduced a static Tile::override() method to allow overriding the construction class for a specific type of chest. This applies to classes as opposed to save IDs, so you can override Chest::class with MyCustomChest::class and it will take effect for any Chest save ID.
- Removed MCPE stringy save ID constants from public Tile interface. These are now only used for creating saved tiles from a stored chunk, and saving them.
- Renamed Tile::registerTile() to register()
- Tile::create() and Tile::createFromItem() now accept a class parameter instead of a stringy save ID.
- Tile::create() and Tile::createFromItem() were changed to throw \InvalidArgumentException on unknown/unregistered tile types. They also now never return null, but always (except in exception cases) return an object which is an instanceof the base class specified.
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.
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.
this parameter was previously used to send blocks with a different set of flags, immediately, to players. However, the flags have been demonstrated useless and the direct sending is pointless now since packets are buffered now per session, so we might as well take advantage of the batched block update sending.
This is a major change to the way block metadata is handled within the PM core. This separates variant metadata (which really ought to be part of the ID) from state metadata, and in a couple of cases flattens separate states of blocks together.
The result of this is that invalid variants can be much more easily detected, and additionally state handling is much cleaner since meta is only needed at the serialize layer instead of throughout the code.
A common pitfall developers fall into with this function is that it has to be called from the scope of the tile class you're creating NBT for, but people commonly do Tile::createNBT() directly, which then results in cryptic "Tile is not registered" errors. This now throws a BadMethodCallException instead to be fully clear about this.
In the future this will be removed completely once NBT is no longer required to create a tile, but for now this is a confusing issue that should be dealt with.
PhpStorm can't see constructor usages when the class name is dynamic. This causes maintenance problems because cross-referencing constructors called like this doesn't show up dynamic calls.
I considered renaming sendDataPacket() to dataPacket() to reduce the BC breaks, but the parameter set has changed, which might cause astonishing behaviour, so it's better to break it in a loud way. Also, this has a clearer name.
* Implemented InventoryEventProcessor, fixes#1986
Event processors can now be registered and unregistered at will. Entity inventory/armor change events are now handled by event processors instead of the inventories themselves, which allows enabling/disabling the calling of these events at will.
This now avoids stupid things happening when initializing inventory contents, since the callers for those events are now registered _after_ the contents are initialized.
