Question about velocity - what's the transfer order when a player gets transferred via /server, or plugin messaging.

What events get fired in what order - on the proxy server, and server A & B (example names ofc).

Lets imagine the player is connected to server A, and wants to transfer to server B. Does the PlayerQuitEvent happen before, or after the player is connected to server B.

warped shard May 20, 2026, 7:27 AM

#

well the pre connect event always fires before any connection is attempted and then first a connection is established with the new backend before disconnecting from the current backend, but I can't remember the specifics

Hold on a second, let's take a step back here. Do you know what's velocity? Have you read the docs on the website https://docs.papermc.io/velocity/ ?
Just like Paper plugins, you can achieve different things based on your needs. You can search on modrinth/hangar for velocity plugins if you want to see some examples of velocity plugins (punishment system, queue, MOTD, etc etc)

Is it intentional that the MAX_COMPRESSION_RATIO check only occurs on serverbound packets? Seems to me like it should actually only happen clientbound (e.g. trust the backend servers)?

#

(would also love access to #velocity-contrib to discuss these things in the proper place)

bold wharf May 22, 2026, 12:09 AM

#

the compression ratio check is in the else block

#

First day back from a short health break, I am still kinda mentally cooked; hope to be back in full swing next week

naive ibex May 22, 2026, 8:06 AM

#

bold wharf the compression ratio check is in the else block

Indeed so the check only occurs serverbound

vast depot May 22, 2026, 12:23 PM

#

what happens when you call RegisteredServer#sendPluginMessage while the connection isn't fully established to the server yet? like when the player is still in the configuration phase on the proxy

#

because I'm getting behaviour that looks like it is silently discarded :S

#

ok, well, not silently I guess, the method returns false in such a case

#

my abstraction hid that away :/

vast depot May 22, 2026, 1:37 PM

#

well it works on Velocity now but even though Bungee has an inbuilt queue (which I assumed Velocity would also do) it's broken there, fml lol

sage otter May 22, 2026, 2:40 PM

#

I don't get why compression between proxy and backends even exists

bold wharf May 22, 2026, 2:46 PM

#

naive ibex Indeed so the check only occurs serverbound

"bound" is the target; clientbound packets are being sent from the server bound to the client, serverbound packets are being sent from the client bound to the server

@sage otter trading CPU for network traffic ¯_(ツ)_/¯ makes sense in some kind of situation e.g. paying for the traffic

sage otter May 22, 2026, 3:48 PM

#

most of the time, proxy and backends are in the same local network. in that case, it's wasted CPU time

upper heath May 22, 2026, 3:52 PM

#

most of the time, but you can't account on every single network being like that, offering the option doesn't hurt anyone, but not offering it hurts the cases where it matters

#

it is a tradeoff after all

naive ibex May 22, 2026, 4:05 PM

#

well, even locally, i've seen peeks of 1gbit in & out on velocity. if a network is split across multiple machines with just a 1gbit switch between them, not compressing packets would bottleneck quickly

#

& it seems odd to require a 10gbit link just for a couple hundred/low thousands of players

vast depot May 22, 2026, 4:11 PM

#

chunk data isn't exactly small

upper heath May 22, 2026, 4:26 PM

#

yeah you can also just set the compression threshold on the server higher than the one between proxy<->client if you really care about <=normal packets lol

bold wharf May 22, 2026, 4:39 PM

#

Minecraft sorta expects the data to be compressed

#

In the past we'd recomemnd anybody routing stuff over a local network to disable compression on the backend, but that doesn't really work exactly because of stuff like the registry packets

naive ibex May 22, 2026, 6:53 PM

#

Does the vanilla client ever send non-compressed packets?

upper heath May 22, 2026, 6:58 PM

#

yes, the compression threshold is sent to the client as well for its own compression handler

bold wharf May 22, 2026, 7:06 PM

#

most serverbound packets are going to be uncompressed, most clientbound packets I'd imagine too

upper heath May 22, 2026, 7:08 PM

#

not if you set the threshold to 0 thinksmart

naive ibex May 22, 2026, 8:36 PM

#

i wonder if an amplification DOS is theoretically possible with a malicious server

#

the server sending small packets to the client, which makes the client send large packets back, effectively dossing itself given a low enough upload bandwidth

#

(cries in DSL upload speed)

vernal compass May 22, 2026, 8:38 PM

#

the client dies before that, pretty sure

naive ibex May 22, 2026, 8:38 PM

#

the client should easily be able to handle sending a handful of megabit

#

my home internet has only 10mbit/s up

vernal compass May 22, 2026, 8:40 PM

#

its surprisingly bad. mostly struggling with packets per second tho

bold wharf May 22, 2026, 8:55 PM

#

The client doesn't really have anything large it could echo back or respond to

upper heath May 22, 2026, 8:56 PM

#

stares at creative mode

bold wharf May 22, 2026, 8:56 PM

#

I was thinking that, but most of that would be inventory related stuff and you'd likely have to find some pretty specific state for it to throw data back

naive ibex May 22, 2026, 9:06 PM

#

i mean you can force the client to do a hell of a lot of things, you can open and close inventories, can you also open & close books, saving them?

#

that would probably make the client echo back a large packet

#

one that compresses well.. as i had noticed 😅

upper heath May 22, 2026, 9:07 PM

#

a single packet tho?

#

doubtful

vernal compass May 22, 2026, 9:09 PM

#

biggest data you can get outside of creative is probably the written book content. but that requires user input

bold wharf May 22, 2026, 9:13 PM

#

Yea, not sure if the client would send anything if the server closed the book UI

naive ibex May 22, 2026, 9:14 PM

#

the limit here is how fast the client will actually allow the book ui to be opened and closed

#

clientbound.register(
          LegacyTitlePacket.class,
          LegacyTitlePacket::new,
          map(0x45, MINECRAFT_1_8, true),
          map(0x45, MINECRAFT_1_9, true),
          map(0x47, MINECRAFT_1_12, true),
          map(0x48, MINECRAFT_1_12_1, true),
          map(0x4B, MINECRAFT_1_13, true),
          map(0x4F, MINECRAFT_1_14, true),
          map(0x50, MINECRAFT_1_15, true),
          map(0x4F, MINECRAFT_1_16, MINECRAFT_1_16_4, true));

why do we pass along a packet's constructor, LegacyTitlePacket::new here, if all map functions are encode only (the true)?

#

the packetSupplier is never stored/used if all mappings are encodeOnly:

if (!current.encodeOnly) {
  registry.packetIdToSupplier.put(current.id, packetSupplier);
}

wouldn't it make sense to make the constructor here @Nullable, throwing in register() if the supplier is null and one or more mappings are NOT encodeOnly?

#

this is regarding a PR i just made - https://github.com/PaperMC/Velocity/pull/1803/changes#r3291203814

see this comment. the only reason we need this constructor here is because StateRegistry requires a constructor, but this constructor will and should never be called.

ommitting the constructor here is the solution, but then StateRegistry gets mad. allowing the packetSupplier to be @Nullable will fix this; we just pass null and omit this constructor

bold wharf May 22, 2026, 9:18 PM

#

Expressing that in code is a pain and a maintanance nightmare, just keeps it within the pattern

naive ibex May 22, 2026, 9:18 PM

#

bold wharf Expressing that in code is a pain and a maintanance nightmare, just keeps it wit...

see my last message though; we now need to define a constructor that must never be called

bold wharf May 22, 2026, 9:19 PM

#

then make the constructor throw?

naive ibex May 22, 2026, 9:19 PM

#

yeah im about to push that. but, it seems wrong

#

having a public no-param constructor that throws

#

clientbound.register(
          LegacyTitlePacket.class,
          () -> throw new IllegalStateException("..."),
          map(0x45, MINECRAFT_1_8, true),

this is another solution. but that clutters StateRegistry.

bold wharf May 22, 2026, 9:20 PM

#

Well, the expectation is that nobody is using the empty constructors other than the caller, and so it shouldn't even matter what the default state of that stuff is

#

The only time that is used is when the read method is going to be called

naive ibex May 22, 2026, 9:21 PM

#

instead of having the constructor supplier be @Nullable we could add registerEncodeOnly that throws if any of its supplied maps are not-encodeOnly

#

do you think that's better?

bold wharf May 22, 2026, 9:21 PM

#

that action shouldn't be final

naive ibex May 22, 2026, 9:21 PM

#

it should, the action will never get manipulated

bold wharf May 22, 2026, 9:21 PM

#

It will be manipulated, in the read method

#

(if one existed)

naive ibex May 22, 2026, 9:22 PM

#

yeah but that's the thing; it doesnt exist

#

all maps are encodeOnly

bold wharf May 22, 2026, 9:22 PM

#

pretend it does for the sake of just keeping tha pattern design the same

naive ibex May 22, 2026, 9:23 PM

#

well

#

the setAction() method was protected before this

#

this was my earlier solution: https://github.com/PaperMC/Velocity/pull/1803/changes/aed4598902c1c4b4297ee8ed6c5f7b8dcb48f8d6

#

keeps the setAction() methods and throws if it's anything but the expected value.

#

do you think this is better?

#

i just dont like having a non-final field that will and should never be changed. a TitleTextPacket's action should never not be SET_TITLE. it doesnt even need the field.

bold wharf May 22, 2026, 9:24 PM

#

My understanding is that most of the time that a packet has a setter it's a design choice based on surrounding code and probably should just not exist on that

naive ibex May 22, 2026, 9:24 PM

#

the setter was only ever used in the factory method in the same package (the setter was protected)

#

btw, we don't even need getAction(). i just kept it in for completeness, because the packets are only ever created off of an action, and the getter returns the same action that was given to the factory method.

#

as of the current state of the PR the getter has no usages

bold wharf May 22, 2026, 9:27 PM

#

hmmmm, so, there is the factory method which really could just pass that in through the constructors, and then the constructors which really should just be using super o.O

naive ibex May 22, 2026, 9:27 PM

#

yep

#

i found it to be a quite weird implementation

#

hence the PR 🙂

#

feel free to look at it tomorrow or at a later date - it does clean up the title packets quite well and functionally changes nothing

#

well, except for the bug that was never reachable, see the PR description

#

public LegacyTitlePacket() {
  // This method only exists to keep StateRegistry happy (all mappings are encode-only, the constructor isn't stored).
  throw new AssertionError("A bare LegacyTitlePacket should never be instantiated");
}

resolved-ish.

if this pattern exists for more encode-only packets, IMO its worth a future refactor

bold wharf May 22, 2026, 9:34 PM

#

I mean, the general gist is that nothing should ever create an instance of a packet without calling the read method, or doing something funky around populating the packet

#

There wasn't really a hard standard on that stuff as packets aren't API and we expect stuff to work how it does

naive ibex May 22, 2026, 9:35 PM

#

well, title packets are created a lot, through the API methods on Player

#

10 usages here, all from ConnectedPlayer (except one from ClientPlaySessionHandler sending a title clear packet)

bold wharf May 22, 2026, 9:35 PM

#

API using it and it being API are two different things

naive ibex May 22, 2026, 9:36 PM

#

oh yeah i get what you mean. though it's good to force these contracts on "ourselves" (the proxy implementation module)

bold wharf May 22, 2026, 9:36 PM

#

I try to be nice and avoid changing internals on zero whim, but, anything inside of .proxy has 0 defined behavior outside of the API and calling it yourself is at your own risk

naive ibex May 22, 2026, 9:37 PM

#

this exception is loud and clear, literally. the previous non-param constructor would keep action null, throwing a random NPE when its trying to be encoded

naive ibex May 22, 2026, 9:38 PM

#

bold wharf I try to be nice and avoid changing internals on zero whim, but, anything inside...

the guys from LimboAPI would like to have a word with you.... they compile against proxy and use a ton of reflection...

#

don't like that at all & ive had to deal with it a lot unfortunately

bold wharf May 22, 2026, 9:38 PM

#

I mean, sure

#

You can also shoot yourself in the foot

#

I can't stop software poking inside of .proxy, and I try to avoid making huge changes blindly in there as sorta an ackowledgement that people do some funky stuff we don't support which makes that unavoidable, but there is no well defined contracts in there, stuff can change, stuff can have weird expectations over how it's used, epsecially for low level data stuff like packets

naive ibex May 22, 2026, 9:41 PM

#

stuff like that is better suited as a fork imo

#

which i beleive LimboAPI was at one point

bold wharf May 22, 2026, 9:42 PM

#

making the packets empty constructor throw is in a weird area of it just being wrong especially as the expectation is that that is only ever called when decode is called, ofc for stuff where we don't decode it, this packet just sorta smells; , but for packet, the fields should just be nullable and so that packet shouldn't ever really be able to exist in a bad state, outside of that weird design pattern flaw

#

I, brain, words, iq limit for today

#

How on earth is it almost 11pm, I need chicken

naive ibex May 22, 2026, 9:43 PM

#

bold wharf I, brain, words, iq limit for today

not just me today luckily

#

yeah so. LegacyTitlePacket()'s only usage is clientbound.register's parameter. this method finds all mappings are encodeOnly = true, which means

if (!current.encodeOnly) {
  registry.packetIdToSupplier.put(current.id, packetSupplier);
}

this NEVER gets called, and this is the only usage of packetSupplier in register().

this is why i think its good to refactor StateRegistry very slightly, either allow packetSupplier to be nullable and throw when it is while we have non-encodeOnly packets. or have a separate registerEncodeOnly which never consumes this constructor, as the constructor is never needed for encodeOnly packets.

still worth a visit at a later date.

bold wharf May 22, 2026, 9:46 PM

#

I mean, if we did that I'd much prefer a seperate method that introducing nullability into the existing one

naive ibex May 22, 2026, 9:47 PM

#

this would completely get rid of any constructor requirements for encodeOnly packets, eliminating what I had to do for LegacyTitlePacket (which is currently also a problem without the merge of my PR, as it leaves action as null)

naive ibex May 22, 2026, 9:47 PM

#

bold wharf I mean, if we did that I'd much prefer a seperate method that introducing nullab...

+1

bold wharf May 22, 2026, 9:47 PM

#

But even there, the whole nature of the empty constructor being an illegal state is 100% expected

#

that case applies for quite literally every single packet, I don't entirely see the engineering justification for seperating specific ones out

naive ibex May 22, 2026, 9:48 PM

#

i dont think thats the case

#

why would we need to store the constructor at all then?

#

its not like we are creating packet classes with Unsafe

bold wharf May 22, 2026, 9:48 PM

#

No but the cost of the lambda is almost nothing

#

and I think that making constructors throw harms the, even if unsupported, wierd cases of people screwing with our packet impls, more than it benefits us from an engineering perspective

naive ibex May 22, 2026, 9:49 PM

#

its just that the StateRegistry never needs to know about any constructor for encodeOnly packets. for packets that it also has to decode, it needs a reference to the (empty) constructor, to call decode() after it right away. for encodeOnly packets it never needs to know of any constructor

bold wharf May 22, 2026, 9:50 PM

#

What I'm saying is that the cost of that reference is trivial so not really a huge factor, but the engineering of making all of the packets which sit in that case throw from the empty constructor feels meh

naive ibex May 22, 2026, 9:50 PM

#

i dont want to throw on an empty constructor

#

i want to get rid of them

#

completely random packet that's encode only - PlayerChatCompletionPacket has a no-arg constructor and one with args.
the no-arg constructor is only referenced in StateRegistry.

with such a refactor, we can get rid of the no-arg constructor completely. this only leaves PlayerChatCompletionPacket(String[] completions, Action action) which is actually called

bold wharf May 22, 2026, 9:51 PM

#

I guess, idk; it falls into a weird area of internal changes

naive ibex May 22, 2026, 9:51 PM

#

currently we need no-arg constructors for encodeOnly packets just as a reference that we throw away immediately.

#

getting rid of needing a reference for encode only packets also gets rid of the need for no-arg constructors on these packets

bold wharf May 22, 2026, 9:52 PM

#

Yea, but getting rid of the no-arg constructors does sorta beat those who want those constructors for weird stuff

naive ibex May 22, 2026, 9:52 PM

#

imo it'd be a nice cleanup, a PR diff with lots of -'s, which i always like

naive ibex May 22, 2026, 9:52 PM

#

bold wharf Yea, but getting rid of the no-arg constructors does sorta beat those who want t...

okay i see this concern

#

but eh

#

using reflection or compiling against the impl module to instantiate packets with no-arg constructors

#

is that really something we should be concerned about supporting?

bold wharf May 22, 2026, 9:53 PM

#

Yea, falls into the area of unsupported but a change I'd be weary of making without a version bump

naive ibex May 22, 2026, 9:54 PM

#

bold wharf You can also shoot yourself in the foot

😛

#

plugins doing these kinds of things would already use plugins like packetevents ig

#

but i agree with a version bump on this one

bold wharf May 22, 2026, 9:55 PM

#

Yes, I try to avoid aiding in pulling the trigger for them but I do need to make some considerations that exists before I break some core oddball plugin

naive ibex May 22, 2026, 9:56 PM

#

plugins doing these kinds of weird things already break all the time, take a look at the commit history here https://github.com/Elytrium/LimboAPI/commits/master/

#

(unfortunately, this is the #5 ranked velocity plugin on bstats with 1.5k servers)

bold wharf May 22, 2026, 9:57 PM

#

I mean, their plugins fall into the border of instant warranty voiders for me

#

but I generally just have a level of adversion to making changes I know will immediatly set the people using such plugins after me, at least not without a version break where there is a fairly well defined target for that sorta thing

naive ibex May 22, 2026, 9:59 PM

#

if it helps, with Velocity-CTD, we have been giving 0 thought about keeping the internals aligned-ish with upstream, and the only breaking plugin that people were complaining about is that one ^ so i think it may be fairly safe

#

we only have about 1-2% of the Velocity installbase but still, might be worth something

bold wharf May 22, 2026, 10:00 PM

#

Well, yea, I just don't have the capacity to check that sorta thing to know what plugins I might or might not break when doing stuff, and so generally just prefer to try to avoid setting a hoard after myself

naive ibex May 22, 2026, 10:02 PM

#

a consistent use of reflection in plugins may suggest the API is lacking on some fronts. making people mad by changing internals could surface these kinds of things, and they can be considered as an actual API feature in the future

#

but yeah im 1 hour ahead of you, and i already had my chicken 😂. im off for now, good night!

bold wharf May 22, 2026, 10:02 PM

sage plank May 23, 2026, 9:19 PM

#

Ah, but that'd rely on a player being online, right?

#

So I wouldn't be able to do it on plugin startup

#

I can work with that though, just waiting until the first player logs in. Tedious but not difficult for my use case

sour current May 23, 2026, 9:20 PM

#

is this for a public plugin or for your own use

sage plank May 23, 2026, 9:21 PM

#

Currently my own use, but may be turned public far down the line

sour current May 23, 2026, 9:21 PM

#

well what i just do with my servers is pass the name to it using a system property

sage plank May 23, 2026, 9:21 PM

#

Another option is defining the server id through a plugin config property, yeah I see what you mean

sour current May 23, 2026, 9:22 PM

#

other plugins like luckperms also just have a config yeah

sage plank May 23, 2026, 9:22 PM

Why is a stable build’s version with SNAPSHOT

bold wharf May 25, 2026, 8:30 PM

#

Because the builds are part of a stable release channel, we haven't really managed proper releases in a while but those would be tagged differently iirc

odd wing May 26, 2026, 11:53 AM

#

How does velocity handle the command list? Since I assume the proxy doesn’t know about the backend command list how can it send a list with the backend and the proxy’s list

rose drum May 26, 2026, 11:54 AM

#

Velocity injects the proxy commands into the command tree whenever the backend server sends it to a player

odd wing May 26, 2026, 11:57 AM

#

Could you guide me to where in the codebase of paper and velocity it does that?

#

Is it through messaging channels?

bold wharf May 26, 2026, 11:57 AM

#

in velocity it's the available commands packet

#

it just modifies the command tree to inject information about commands on the proxy

odd wing May 26, 2026, 12:01 PM

#

Yeah but how tho, you say modified but how does it have the original list

bold wharf May 26, 2026, 12:02 PM

#

it doesn't have the original list

#

it has the command tree that the server sends to the client

odd wing May 26, 2026, 12:04 PM

#

What about registering a new command on the proxy during runtime

#

Cause the backend won’t send a packet then right

bold wharf May 26, 2026, 12:05 PM

#

Correct, the client just won't know about that command until you do something that triggers the backend to resend the command tree

odd wing May 26, 2026, 12:05 PM

#

Ah crap

#

Alright

#

Thanks

bold wharf May 26, 2026, 12:06 PM

#

mojang only supports resending the full tree, if you were doing plugin stuff you'd need a plugin on the backend that can take a plugin message or something to resend the tree

odd wing May 26, 2026, 12:06 PM

#

Alright

#

So a possible fix by mojang would just be changing the packet to also allow additions/removals

#

Is there a reason paper doesn’t provide a patch for that

bold wharf May 26, 2026, 12:08 PM

#

Because we can't modify the client

is there anything in velocity to communicate to servers without players or would i have to setup my own sockets?
And if so, any good libs for that? I used https://github.com/jhg023/SimpleNet before but ran into a critical bug there that really limited what i could use it for (https://github.com/jhg023/SimpleNet/issues/23)

fossil sundial Nov 15, 2021, 9:50 PM

#

meager sluice is there anything in velocity to communicate to servers without players or would...

Well I don’t recommend it but I’ve seen plugins abuse server pings (back and forth) with custom data in them to communicate
Otherwise if you just need something simple to communicate you can look at RabbitMQ for example

meager sluice Nov 15, 2021, 9:51 PM

#

Thanks

#

could also use plain java sockets but effort

fossil sundial Nov 15, 2021, 9:55 PM

#

If it’s for effort okhttp3 also has a simple solution for that

meager sluice Nov 15, 2021, 9:56 PM

#

i basically want to pass warp information between servers

young pilot Nov 15, 2021, 9:56 PM

#

Well then my suggestion is not the best, but I'll still recommend it: gRPC / REST (if you need them in some web context potentially)

#

could use MQTT for auto discovery and setup some grpc or something

#

But that's not useful for a simple public plugin I guess, that's rather overengineered

meager sluice Nov 15, 2021, 9:57 PM

#

i'm all for overengineering

young pilot Nov 15, 2021, 9:57 PM

#

replace MQTT with Message Broker actually, there are a few, yeah

#

but actually could maybe make a central "warp control node" that stores them and have all the game servers talk to it

meager sluice Nov 15, 2021, 9:58 PM

#

yeah that was my idea, basically use the proxy as that node and have all servers communicate through that

#

tbh the java sockets dont look so bad either

young pilot Nov 15, 2021, 10:00 PM

#

I guess the fastest is like a "sparkjava" rest server

#

Fastest as in rapid prototyping

#

plain sockets don't give you any persistency, encryption etc

meager sluice Nov 15, 2021, 10:01 PM

#

im not planning on encrypting warps lol

young pilot Nov 15, 2021, 10:01 PM

#

hmm true

#

but you still need the codec

meager sluice Nov 15, 2021, 10:01 PM

#

the players will never get access to that info anyway

young pilot Nov 15, 2021, 10:01 PM

#

like funny string splits

#

well they can if the backend servers are not firewalled properly

meager sluice Nov 15, 2021, 10:02 PM

#

thats not my problem

young pilot Nov 15, 2021, 10:02 PM

#

but that's not the encryption thing here anyway

#

and yeah, probably not important

#

but a gotcha

Presumably, you've read up about what Velocity can do for you. But how does it stack up against other solutions out there? We're biased, so…

but bungeecord randomly keeps telling me the login event took x ms to process

because of some bad plugin that idk what is

so if i use velocity i'll be forced to code it myself since velocity doesn't have versions of these plugins
therefore if i code it myself it won't be bad

I don't know where you conceived the idea that Velocity is harder to work with. On the contrary, it's much easier and better to work with than BungeeCord.

BungeeCord's API is poorly documented and badly architectured. It returns undocumented null values, fails to check invariants, and couples API and implementation. API objects provide very little guarantees about nullability.

#

BungeeCord uses singletons and global state, exposes an error-prone API for async events, and uses the bungeecord chat API.

Velocity's API is perfect for dependency injection and uses the Adventure API for chat messages and whatnot.

because i need multiple instances of the same plugin, what??

oblique haven Nov 16, 2021, 9:51 PM

#

agile ore because i need multiple instances of the same plugin, what??

more like velocity's framework doesn't require everything to be linked together under a superclass

#

public class SomeVelocityPlugin {} is valid for example, and there's no superclass to bind with, so that "global state instance" doesn't make sense

#

it also forces a decent structure of things, and if you'd like, you can break everything and declare all the stuff static, but it's not a good idea generally

#

especially for things like making your environment testable

#

in bungeecord, to even setup a testable environment you need to mock the entire proxy server class

wary tiger Nov 16, 2021, 10:38 PM

#

for the purpose of running tests. If the tests shared global state, then they would interfere with each other

oblique haven Nov 16, 2021, 10:47 PM

#

testing in java heavily consists of being able to create and stub data

#

global state really hurts that

bold wharf Nov 16, 2021, 10:48 PM

I mean, that's pretty much testing in any sane environment

individual tests of which can be as long or complex as needed to test an individual case against an individual instance of the software

stray cedar Nov 16, 2021, 11:25 PM

Interesting to hear about Waterfall being deprecated. Probably good news, though of course it's quite a tall order for devs and server owners as Velocity and Waterfall/BungeeCord are different platforms.
I do a bunch of cross-server stuff that uses Bungee plugin messages - I'd like to know if the BungeeCord plugin messaging channel is supported on Velocity proxies. I hear that BungeeQuack implements it which was merged into Velocity via https://github.com/VelocityPowered/Velocity/pull/255, though it's unclear if this means that existing plugins using the Bungee messaging channel currently will just work?

#

If not, what would I need to change from a current implementation of sending plugin messages in Spigot (and by extent Paper) such that it'll work. (By current implementation, I mean as per these docs: https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/)

haughty summit Nov 17, 2021, 9:47 PM

#

Yes, but you'll never see that message unless you explicitly would go to example.com:25565, which you rarely will specify the ports, so I think it's safe to assume it'd have to listen on :80 (or even :443 if you want to get certs, but that unnecessarily complicates it further).

warm gulch Nov 17, 2021, 9:48 PM

fossil sundial Nov 17, 2021, 10:42 PM

The final reason why this is a hard no is stability and security. Velocity has a tightly regulated protocol to ensure the proxy exposes as little attackable surface as possible. Foreign protocols are not on the list for this.

Then you need to make a plugin for velocity to delegate that information

#

But beware, you can only use plugin messaging if you have a player connected to the server you want to send it to

#

Otherwise you’d have to use another way

#

See #velocity-help and scroll up a bit for solutions that don’t use plugin messaging

but now

how*

fossil sundial Nov 20, 2021, 9:59 AM

agile ore how*

? Check that the events invoker isn’t on the server you don’t want this to execute from

agile ore Nov 20, 2021, 10:00 AM

#

how do i check that 👀

fossil sundial Nov 20, 2021, 10:01 AM

#

you check if the events invoker is instanceof Player, if yes cast it to player, then check if the player has a current server with isPresent and if yes get the server and get the info and then check the name?

#

I’m not going to give you a Java tutorial

Otherwise no, unless, again, you use another solution

Quick question, if I wanted to change the UUID of a Player when they first join the proxy, can I simply listen for the GameProfileRequestEvent, rebuild the GameProfile with the provided properties minus the UUID, and then GameProfileRequestEvent#setGameProfile?

#

I'm reading through the LoginSessionHandler and it seems to be the case, since it fires that event and uses the result to create ConnectedPlayer

#

Also, would there be any unintended side effects of doing that, only asking from Velocity's standpoint as I manage everything using the UUID afterwards

fossil sundial Nov 23, 2021, 7:34 AM

#

fallen yacht Also, would there be any unintended side effects of doing that, only asking from...

No there aren’t. Fair warning; a custom UUID will be ignored if you don’t have forwarding set up. In that case velocity will send the user the same UUID it would have on an offline-mode server to not break game features. So as long as you have forwarding enabled and the fake “online-mode” for your forwarding is also enabled on the servers then this will just work fine

Kotlin ?

You need to add the annotationprocessor

#

If using kotlin use kapt

fallen yacht Nov 24, 2021, 3:53 AM

ah it is kotlin, yeah

#

ok I'm compiling with jvm 16 and kapt seems to have problems with that

is there a way I can like manually do it without using any annotation processor

all right I've checked the source & found that it's just a json object basically with the values of the annotation + the fqcn of the plugin class

Tbh, this annotation retention being runtime is bad. It's not used in runtime for real, yet someone actually might do it anyway. And then you can possibly get a diff between annotation and a .json description file.

So I have this code here that's meant to take me between servers

        try {
            ConnectionRequestBuilder connector = (player).createConnectionRequest(this.server);
            connector.connect().thenAccept(result -> {
                if (!result.isSuccessful()) {
                    source.sendMessage(Component.text("Unable to connect:\n" + result.getReasonComponent()).color(NamedTextColor.RED));
                }
            });
        } catch (Exception exception) {
            this.logger.error("Error:", exception);
            source.sendMessage(Component.text("An internal error occurred:").color(NamedTextColor.RED));
        }``` and it works, but for some reason it doesn't catch errors where the server is down (connection refused), resulting in an exception being printed to the console and absolutely no response from the proxy. Is there a special way to catch exceptions or should I add a check to make sure the server is reachable before trying to join it?

bold wharf Nov 26, 2021, 9:55 PM

#

I mean, boils down to where the exception is actually coming from

#

if connect does stuff with a figure, your try catch is irrelevant

#

so, you'd probs want the whenComplete thing which might pass down the exception?

knotty mica Nov 26, 2021, 10:05 PM

I'll give that a try, thanks!

Works

spiral portal Nov 26, 2021, 10:23 PM

or add a "catch" using .exceptionally() after the thenAccept

something like

connector.connect().thenAccept(result -> {

}).exceptionally(throwable -> {

Velocity uses a ThreadPool to do that. Nothing is stopping you from just making and using your own

is there performance comparaison between bungeecord based proxy and Velocity ? And is it worth to migrate if we have only 2 plugins to migrate ?

trim otter Dec 2, 2021, 1:50 PM

#

That is more #velocity-help question. But you can read https://velocitypowered.com/wiki/users/what-does-velocity-do-for-me/ and https://velocitypowered.com/wiki/users/comparisons-to-other-proxies/ then decide for yourself. Imo with only 2 plugins the migration will be fairly simple so I'd go for it!

Yes there are major performance benefits.

The server I’m a developer for saw major improvements in resource usage for both RAM and CPU, while maintaining very similar bandwidth usage.

I’d recommend it over bungee or waterfall any day

There’s also a cleaner API to work with on the plugin end. (This is opinion based but still)

That’s still theoretically possible (speaking for 1.12.2 and older)
But it’s not a feature in the api
However velocity has an event that at least gives you the list of the clients mods: https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/event/player/PlayerModInfoEvent.html

#

the only mention of ratelimits is for the UUID to Skin API request, and it simply says "This has no ratelimit."

agile ore Dec 9, 2021, 4:30 PM

#

You should note that all public APIs are rate limited so you are expected to cache the results. This is currently set at 600 requests per 10 minutes but this may change.

fossil sundial Dec 9, 2021, 4:52 PM

#

Adding onto that it’s an increasing rate limiter

#

So the more requests you do the lower the ceiling gets

Won't be disclosed for a while, make sure you upgrade

The posted link only seems to show versions up to 3.1.0 for velocity, am I missing something? Thought the post said 3.1.1 had the fix?

fossil sundial Dec 9, 2021, 7:27 PM

#

The other builds section has it; see the build number in #announcements

I’m very sorry for this mess

It looks like a vulnerability in <censored>. Do we know what kind of security vulnerability we are looking at, whether Spigot 1.17.1 servers are also vulnerable and whether having an updated proxy protects servers after it or not?

Perhaps the build #97 should be pinned on the website download section?

I've read it and I don't believe that these questions were answered.

(Redacted, just found out we were asked not to share this)
whether Spigot 1.17.1 servers are also vulnerable
Probably? I can check the dep tree but, assume yes anyway.
whether having an updated proxy protects servers after it or not
This depends on your setup, I say upgrade everything and don't take any chances

how severe is the exploit?

#

as in, do I need to put my server in maintenance mode until we have it ported to our custom fork?

yes.

bold wharf Dec 9, 2021, 8:05 PM

mostly a DoS attack so it seems right now

vestal prawn Dec 9, 2021, 8:30 PM

#

If we have velocity 3.1.1, does it protect every spigot servers behind the proxy ?

#

Or do we need the patch on every single spigot server

bold wharf Dec 9, 2021, 8:31 PM

#

no, yes

vestal prawn Dec 9, 2021, 8:31 PM

You are very likely upgrading from Velocity 1.x.x to 3.x.x. The adventure library was replaced in between those versions. There was an upgrade post on velocitypowered.com, but I can't find it.

stray wind Dec 9, 2021, 8:39 PM

Uggh, isn't it https://velocitypowered.com/wiki/developers/porting-from-velocity-1/ ?

raw frost Dec 9, 2021, 8:42 PM

#

Yes indeed, oh, the Adventure library was actually a replacement for an old text library. I do recall that I had to update some imports. I'm not sure then, but that class doesn't seem to be in his runtime environment.

fickle roost Dec 9, 2021, 8:44 PM

I tried to use this library, but it not helps, even if i tell maven the scope "runtime" 😦

You do need some maven shade plugin that actually packages this dependency with your plugin if it's not in Velocity already.

#

But I'm pretty sure that Velocity offers something that you can use for what you're trying to do with that library.

I'm not saying that you should copy this without reading, but you can try something like this: https://github.com/Pieter12345/JavaLoader/blob/master/JavaLoader-Velocity/pom.xml#L51-L75

The Velocity development download link at https://velocitypowered.com/downloads is down (error 1001, worker threw exception). Is there a new official place to download Velocity since the move to PaperMC?

I'd like to announce that after 4 months of using velocity 1.9 in fear of updating to 3.x because of some plugins being incompatible, I finally did it for the exploit and literally everything fucking works fine why did I dread it to the point I didn't even try waaaaaaa

How do I get rid of the joinmessage and leavemessage for inter-server moves?

frigid rivet Dec 10, 2021, 12:16 AM

#

You'd need to do that on each backend server. Velocity doesn't control that.

Just follow the license (GPLv3) for the proxy/natives code; Your fork will have to be open-source if you plan on distributing it (network use doesn’t qualify as distribution so if you’re just using it yourself you’re not required to do that)
