Subject: [PATCH] Tuinity Server Changes
Brand changes
MC-Dev fixes
Util patch
Tuinity Server Config
Multi-Threaded Server Ticking Vanilla
This patch is the vanilla server changes
Currently a placeholder patch.
Multi-Threaded ticking CraftBukkit
These are the changes to CB
Currently a placeholder patch.
Add soft async catcher
Must be enabled via -Dtuinity.strict-thread-checks=true
Delay chunk unloads
Chunk unloads are now delayed by 1s. Specifically, ticket level
reduction is delayed by 1s. This is done to allow players to
teleport and have their pets follow them, as the chunks will no longer
unload or have entity ticking status removed.
It's also targetted to reduce performance regressions when
plugins or edge cases in code do not spam sync loads since chunks
without tickets get unloaded immediately.
Configurable under `delay-chunkunloads-by` in config.
This patch replaces the paper patch as the paper patch only
affects player loaded chunks, when we want to target all
loads.
Attempt to recalculate regionfile header if it is corrupt
Instead of trying to relocate the chunk, which is seems to never
be the correct choice, so we end up duplicating or swapping chunks,
we instead drop the current regionfile header and recalculate -
hoping that at least then we don't swap chunks, and maybe recover
them all.
Lag compensate block breaking
Use time instead of ticks if ticks fall behind
Update version fetcher repo
Sets the target github repo to Tuinity in the version checker. Also disables the jenkins build lookups.
Per World Spawn Limits
Detail more information in watchdog dumps
- Dump position, world, velocity, and uuid for currently ticking entities
- Dump player name, player uuid, position, and world for packet handling
Execute chunk tasks mid-tick
This will help the server load chunks if tick times are high.
Change writes to use NORMAL priority rather than LOW
Should limit build up of I/O tasks, or at least properly
indicate to server owners that I/O is falling behind
Allow controlled flushing for network manager
Only make one flush call when emptying the packet queue too
This patch will be used to optimise out flush calls in later
patches.
Consolidate flush calls for entity tracker packets
Most server packets seem to be sent from here, so try to avoid
expensive flush calls from them.
This change was motivated due to local testing:
- My server spawn has 130 cows in it (for testing a prev. patch)
- Try to let 200 players join spawn
Without this change, I could only get 20 players on before they
all started timing out due to the load put on the Netty I/O threads.
With this change I could get all 200 on at 0ms ping.
(one of the primary issues is that my CPU is kinda trash, and having
4 extra threads at 100% is just too much for it).
So in general this patch should reduce Netty I/O thread load.
Time scoreboard search
Plugins leaking scoreboards will make this very expensive,
let server owners debug it easily
Make CallbackExecutor strict again
The correct fix for double scheduling is to avoid it. The reason
this class is used is because double scheduling causes issues
elsewhere, and it acts as an explicit detector of what double
schedules. Effectively, use the callback executor as a tool of
finding issues rather than hiding these issues.
This patch also reverts incorrect use(s) of the class by paper.
- getChunkFutureAsynchronously
There is no risk at all of recursion. The future is executed on
the chunk provider's thread queue, the same place general plugin
load callbacks are executed on. Forcing the task execution into
the callback executor also prevents the future from catching
any exception thrown from it.
Optimise entity hard collision checking
Very few entities actually hard collide, so store them in their own
entity slices and provide a special getEntites type call just for them.
This reduces entity collision checking impact (in my testing) by 25%
for crammed entities (shove 130 cows into an 8x6 area in one chunk).
Less crammed entities are likely to show significantly less benefit.
Effectively, this patch optimises crammed entity situations.
Improved oversized chunk data packet handling
Now target all TE data, except for TE's that do not have
update packets.
This patch relies upon the improve extra packet handling
patch, as we now use PacketPlayOutMapChunk as an extra packet.
See its patch notes for further details.
Reduce iterator allocation from chunk gen
Replace via iterating over an array
Prevent long map entry creation in light engine
Use fastiterator to prevent it
Highly optimise single and multi-AABB VoxelShapes and collisions
Reduce allocation rate from crammed entities
Optimise chunk tick iteration
Use a dedicated list of entity ticking chunks to reduce the cost
Use entity ticking chunk map for entity tracker
Should bring us back in-line with tracker performance
before the loaded entity list reversion.
Improve paper prevent moving into unloaded chunk check
Check the AABB of the move
Improve async tp to not load chunks when crossing worlds
Fixes an issue where a getCubes call would load neighbouring chunks.
Loads less chunks than paper's implementation
Revert getChunkAt(Async) retaining chunks for long periods of time
Rework PlayerChunk main thread checks
These need to fail instead of continuing, as hiding these errors
the way paper has is just going to allow unexpected reordering
of callbacks.
For example, thanks to this patch incorrect future
completion (completion of the world gen future,
PlayerChunkMap#b(PlayerChunk, ChunkStatus)) was detected and fixed.
Allow Entities to be removed from a world while ticking
Fixes issues like disconnecting players while ticking them, or
issues where teleporting players across worlds while ticking.
Also allows us to run mid tick while ticking entities.
Prevent unload() calls removing tickets for sync loads
Prevent log spam for "Block is water but TE is chest"
Happens when breaking a waterlogged chest.
Fix is to just not validate the TE while the chest is being removed.
Optimise collision checking in player move packet handling
Don't need to do another getCubes call if the move() call
doesn't find any collisions
Manually inline methods in BlockPosition
Separate lookup locking from state access in UserCache
Prevent lookups from stalling simple state access/write calls
Distance manager tick timings
Recently this has been taking up more time, so add a timings to
really figure out how much.
Name craft scheduler threads according to the plugin using them
Provides quick access to culprits running far more threads than
they should be
Fix swamp hut cat generation deadlock
The worldgen thread will attempt to get structure references
via the world's getChunkAt method, which is fine if the gen is
not cancelled - but if the chunk was unloaded, the call will block
indefinitely. Instead of using the world state, we use the already
supplied generatoraccess which will always have the chunk available.
Range check flag dirty calls in PlayerChunk
Simply return.
Optimise tab complete
Some of the toLowerCase calls can be expensive.
Do not allow ticket level changes while unloading playerchunks
Sync loading the chunk at this stage would cause it to load
older data, as well as screwing our region state.
Make sure inlined getChunkAt has inlined logic for loaded chunks
Tux did some profiling some time ago and showed that the
previous getChunkAt method which had inlined logic for loaded
chunks did get inlined, but the standard CPS.getChunkAt
method was not inlined.
Paper recently reverted this optimisation, so it's been reintroduced
here.
Temporarily Revert usage of Region Manager
Has some stability issues.
Add packet limiter config
Example config:
packet-limiter:
kick-message: '&cSent too many packets'
limits:
all:
interval: 7.0
max-packet-rate: 500.0
PacketPlayInAutoRecipe:
interval: 4.0
max-packet-rate: 5.0
action: DROP
all section refers to all incoming packets, the action for all is
hard coded to KICK.
For specific limits, the section name is the class's name,
and an action can be defined: DROP or KICK
If interval or rate are less-than 0, the limit is ignored
Optimise closest entity lookup used by AI goals
Use a special entity slice for tracking entities by class as well
as counts per chunk. This should reduce the number of entities searched.
Optimise EntityInsentient#checkDespawn
Use a distance map to map out close players.
Note that it's important that we cache the distance map value per chunk
since the penalty of a map lookup could outweigh the benefits of
searching less players (as it basically did in the outside range patch).
Remove streams for villager AI
POI searching:
Turns out chaining a lot of streams together has inane amounts of
overheard. Use the good ol iterator method to remove that overhead.
The rest is just standard stream removal.
Also remove streams for poi searching in some zombie pathfinding.
Don't lookup fluid state when raytracing
Just use the iblockdata already retrieved, removes a getType call.
Reduce pathfinder branches
Reduce static path type detection to simple lazy-init fields
Add Velocity natives for encryption and compression
Optimise non-flush packet sending
Places like entity tracking make heavy use of packet sending,
and internally netty will use some very expensive thread wakeup
calls when scheduling.
Thanks to various hacks in ProtocolLib as well as other
plugins, we cannot simply use a queue of packets to group
send on execute. We have to call execute for each packet.
Tux's suggestion here is exactly what was needed - tag
the Runnable indicating it should not make a wakeup call.
Big thanks to Tux for making this possible as I had given
up on this optimisation before he came along.
Locally this patch drops the entity tracker tick by a full 1.5x.
Do not retain playerchunkmap instance in light thread factory
The executor returned is finalizable and of course
that causes issues.
Do not load chunks during a crash report
This causes deadlocks in some cases when generating
crash reports.
Fixes https://github.com/Spottedleaf/Tuinity/issues/215
Improve abnormal server shutdown process
- When we're trying to kill the main thread from watchdog,
step up the stop() spamming after 15s to really kill the main thread.
- Do not wait for window disposing when disposing of the server
gui. It looks like during sigint shutdown there can be some
deadlock between the server thread and awt shutdown thread here.
Copy passenger list in enderTeleportTo
Fixes https://github.com/Spottedleaf/Tuinity/issues/208
Revert MC-4 fix
When messing around with collisions, I ran into problems where
entity position was off by ULP and that caused clipping problems.
Now, the collision epsilon is 1.0e-7 to account for those errors.
But this patch is going to cause problems on the order of 1.0e-4.
I do not want to deal with clipping problems. The very fact it works
shows it's causing the clipping to occur serverside.
Prevent light queue overfill when no players are online
block changes don't queue light updates (and they shouldn't)
Do not add passengers of entities that were were above save limit
Given that the root entity isn't added to the world, this is
pretty unsafe to do.
Rewrite the light engine
The standard vanilla light engine is plagued by
awful performance. Paper's changes to the light engine
help a bit, however they appear to cause some lighting
errors - most easily noticed in coral generation.
The vanilla light engine's is too abstract to be modified -
so an entirely new implementation is required to fix the
performance and lighting errors.
The new implementation is designed primarily to optimise
light level propagations (increase and decrease). Unlike
the vanilla light engine, this implementation tracks more
information per queued value when performing a
breadth first search. Vanilla just tracks coordinate, which
means every time they handle a queued value, they must
also determine the coordinate's target light level
from its neighbours - very wasteful, especially considering
these checks read neighbour block data.
The new light engine tracks both position and target level,
as well as whether the target block needs to be read at all
(for checking sided propagation). So, the work done per coordinate
is significantly reduced because no work is done for calculating
the target level.
In my testing, the block get calls were reduced by approximately
an order of magnitude. However, the light read checks were only
reduced by approximately 2x - but this is fine, light read checks
are extremely cheap compared to block gets.
Generation testing showed that the new light engine improved
total generation (not lighting itself, but the whole generation process)
by 2x. According to cpu time, the light engine itself spent 10x less time
lighting chunks for generation.
fixup! Highly optimise single and multi-AABB VoxelShapes and collisions
Revert Temporarily-Revert-usage-of-Region-Manager
Optimise WorldServer#notify
Iterating over all of the navigators in the world is pretty expensive.
Instead, only iterate over navigators in the current region that are
eligible for repathing.
fixup! Util patch
fixup! Util patch
Actually unload POI data
While it's not likely for a poi data leak to be meaningful,
sometimes it is.
This patch also prevents the saving/unloading of POI data when
world saving is disabled.

+ Specification for managing the initialisation and de-initialisation of skylight nibble arrays:
+
+ Skylight nibble initialisation requires that non-empty chunk sections have 1 radius nibbles non-null.
+
+ This presents some problems, as vanilla is only guaranteed to have 0 radius neighbours loaded when editing blocks.
+ However starlight fixes this so that it has 1 radius loaded. Still, we don't actually have guarantees
+ that we have the necessary chunks loaded to de-initialise neighbour sections (but we do have enough to de-initialise
+ our own) - we need a radius of 2 to de-initialise neighbour nibbles.
+ How do we solve this?
+
+ Each chunk will store the last known "emptiness" of sections for each of their 1 radius neighbour chunk sections.
+ If the chunk does not have full data, then its nibbles are NOT de-initialised. This is because obviously the
+ chunk did not go through the light stage yet - or its neighbours are not lit. In either case, once the last
+ known "emptiness" of neighbouring sections is filled with data, the chunk will run a full check of the data
+ to see if any of its nibbles need to be de-initialised.
+
+ The emptiness map allows us to de-initialise neighbour nibbles if the neighbour has it filled with data,
+ and if it doesn't have data then we know it will correctly de-initialise once it fills up.
+
+ Unlike vanilla, we store whether nibbles are uninitialised on disk - so we don't need any dumb hacking
+ around those.
