really we should look into making the server stop if any world fails to load, but flooding the place with crashdumps isn't the way to do it.
This is a simplified version of cf73c7f5c1
the timeout was entirely useless, because:
- when shorter than 25.6 seconds (512 ticks) it would cause caches to be needlessly destroyed and regenerated
- when longer than 25.6 seconds, just made outdated caches persist for longer, even after the query info was regenerated.
This now uses a mark-dirty model to deal with caches, which means that plugin modifications to the query data will be reflected immediately, regardless of when they are made. Previously, modifying the result of Server->getQueryInformation() would have inconsistent results.
it's much less expensive to just calculate the modulo of the current tick and 20, and overwrite past entries. The effect is the same. The only difference is that the arrays won't be ordered by time, but that doesn't matter anyway.
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 allows to save the language without rewriting pocketmine.yml. Since this is a "standard" config option (something that the user might want to directly modify) it's reasonable to put it in server.properties. pocketmine.yml is generally reserved for more advanced configuration options.
this technically involves non-breaking API changes which should happen on a patch release, but I can't be bothered with the dust cleanup, so we'll just blow it away now. It doesn't hurt anyone anyway.
This is an incremental improvement over 4a6841a5a4. This change works better because it also reduces disk spam of crashdumps.
This will now sleep if the server uptime was less than 120 seconds before crashing. If unattended, this will clamp down on automated crashdump spam. If attended, the user can simply press CTRL+C to abort the process and skip the delay.
this should produce some reduction in spam at the source.
This could also be used to control the rate at which constantly-crashing servers restart to stop them spamming the disk as well, but the main concern here is eliminating crash archive involuntary DDoS by crashy servers.
