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.
It was still possible to produce undefined behaviour by creating a db folder in a region-based world, or adding regions to a leveldb world. This now solves the problem completely by refusing to load the world if multiple formats match the world.
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 needs further changes (particularly to Furnace) to stop things abusing NBT for runtime data handling, otherwise performance is going to drop off a cliff.
Plugins may cause this issue unexpectedly by unloading levels directly during events such as EntityDamageEvent. This adds a better error message to allow developers to understand what is going on and create appropriate workarounds.
This can be enabled or disabled using the "online-mode" directive in
server.properties.
NOTE: For safety reasons it is enabled by default, since many naive server owners currently believe that authentication is not needed because "the client is forced to sign-in".
Newsflash for readers: the forced authentication is easily bypassed using a LAN proxy.
Un-authenticated LAN connections will still work fine if the online mode is disabled.
Added the following API methods:
- Server->getOnlineMode() : bool
- Server->requiresAuthentication() : bool
- Player->isAuthenticated() : bool
JWT verification is rather expensive, so it is done in an AsyncTask. Make sure you don't hog your worker threads.
