get was calling toString() on every NBT object that was ever asked for an optional
key from the object to build a string for the error text.
When done on large NBT objects, this was using a ton of computation time building the
JSON representation of the NBT object.
Now we will just skip the value when 99.9999% of the time the text is never even printed.
testserver - use printf instead of echo, as echo is apparently
inconsistent across environments
requireDeps - change message slightly, maybe more useful to people?
Mojang precaches every single potential rewrite rule that could ever
exist on server startup. This includes rules from all the way back to versions from 6+ years ago.
This is the source of why the server hogs every CPU core at 100% every start.
For anyone who hard resets for updates or has force upgraded their entire world, this
results in completely wasted cpu cycles.
This massive CPU usage also delays server startup time.
We improve this by making "min version to precache" that defaults to a future version
so that no rewrite rules are precached.
someone who expects to be converting a lot chunks could theoretically set
-DPaper.minPrecachedDatafixVersion=<dataVersionConvertingFrom> as a startup
parameter and only build from that point on.
However this will likely never be needed as the server will still run
the same cache logic on demand when it's actually needed. The only
cost would be some delay on the FIRST chunk conversion, but paper already
runs chunk conversions on another thread so this will likely never be
a concern for TPS.
This patch will significantly reduce CPU use on startup, reduce memory usage,
and improve server startup time.
Spigot has been stripping the minecraft-server jar down in order to
reduce it's size, primarily by removing classes they don't use from
fastutil. as we use fastutil and offer it as API, this is useless
to us, and creates headaches when it breaks builds due to spigots
version of this being installed.
PaperMC believes that 1.16.2 is now ready for general release as we fixed the main issue plagueing the 1.16.x release, the MapLike data conversion issues.
Until now, it was not safe for a server to convert a world to 1.16.2 without data conversion issues around villages and potentially other things. If you did, those MapLike errors meant something went wrong.
This is now resolved.
Big thanks to all those that helped, notably @BillyGalbreath and @Proximyst who did large parts of the update process with me.
Please as always, backup your worlds and test before updating to 1.16.2!
If you update to 1.16.2, there is no going back to an older build than this.

Remove patcehs we know need to go
add comment on one im not sure should be dropped
go ahead and fix patched repos to turn off gpg signing, as this
helps rebase/apply --continue commands not suck.
Go ahead and prep the pom file change
This is for 2 reasons:
1) Ensuring our log4j is mostly loaded at OUR version.
I've seen stack traces with line numbers that do not match our version. This means that some
plugin has shaded in log4j and their loaded version is mixing with ours....
So by at least trying to load a bunch of log4j classes before we load plugins, we can be
more sure mixed versions are not loading.
2) If the jar file is replaced while the server is runnimg class not found errors galore
This will preloaod a bunch of classes commonly seen to error during shutdown due to this.
The goal here is to help let the server shutdown gracefully as possible. Some plugins will
still blow up here if they access a class that hadn't been loaded yet, but goal is to at least
stop freezing the shutdown process as it does with JLine and Log4j errors requiring an external kill.
Ideally you should not replace jars while the server is running, but it is something that happens in
development for testing.
Updated test server to do a copy though to avoid this happening in Paper development.
I believe this brings us back to stable. A lot of complexity was
learned about juggling priorities.
We were essentially promoting more chunks to urgent than really
needed to be urgent.
So this commit adds a lot more logic to juggle neighbor priorities
and demote their priority once they meet the requirements needed of
them.
This greatly improves the performance of "urgent" chunks".
Fixes#3410Fixes#3426Fixes#3425Fixes#3416
Dynmap accessed the raw bytes because it utilized NBT locally, but the
NBTTagcompound was garbage collected while the bytes were still being used.
This will return getBytes() back to being safe, and add a new PoolSafe method
that will prevent the additional allocations for general chunk loading.
Also fixed applyPatches for people with paths in their working directory
if they have mcdev sources built.

Implementation developer note:
This patch adds a "pre-source" patch system for fixing malformed patches
from upstream directly. This seems to keep happening so it's best we
have some way to deal with them. This system brings those issues into
our domain rather than needing to wait for upstream to fix their
malformed files.
this will help ensure that upstreams apply as cleanly as it does manually
the filtering makes the patches more fragile, but usually not an issue for small updates.
this will unfilter, apply the cleanest patches, then the next rebuild will
filter out unnecessary changes
