a couple of usages of properties that no longer exist couldn't be migrated.
in addition, this revealed a couple of dead properties in the default file.
this is not an ideal solution (I'd much rather model the configs using classes and map them) but in the absence of a good and reliable library to do that, this is the next best thing.
until now, any thread crash would show as a generic crash since we aren't able to get the trace from the crashed thread directly. This uses some dirty tricks to export a partially serialized stack trace to the main thread, where it can be written into a crashdump.
This enables us to see proper crash information for async tasks in the crash archive (finally!!!) as well as being able to capture RakLib errors properly.
this was previously part of the abandoned package pocketmine/spl. It had to be separated in the PM3 days, because RakLib depended on it.
Since RakLib 0.13, RakLib stopped being dependent on or aware of pthreads, so it no longer depends on any thread-related packages.
It's also possible to absorb pocketmine/snooze and pocketmine/classloader back into the core with this in mind.
there's a bunch of places we can't reach with this right now:
- particles
- sounds
- tile NBT
- entity metadata
- crafting data cache
- chunk encoding
- world block update encoding
this is a work in progress, but ultimately we want to get rid of these singletons entirely.
since this is contextless (there's no way to know the version of the client requesting the MOTD), we can safely assume that this is not going to vary between protocol versions.
I previously avoided this due to being unsure of the effects; however, it's clear that we already use typed properties on Threaded things in other places anyway, and the only known issues are with uninit properties, and arrays.
this gains a very small performance improvement by avoiding unnecessary !== null checks on every packet written in either direction. It's insignificant for sure, but I just found this code in an old stash, so what the heck.
