catmoe/blessing

Recoding of MoeFilter. A utility created for Minecraft: Java Edition server/proxy.

blessing's Issues

(protocol): adds encode / decode support for clients.

Currently, the protocol module only provides decoding as a server. If we can use it for clients (for example, make tools for requesting other server status.). It could be more useful.

`catmoe.fallencrystal.moefilter.network.limbo.handler.MoeLimbo : connections` 的并发读写异常

IPTables & IPSet功能测试

我在 7b8c2c2 提交中引入了iptables & ipset支持 但我目前没有合适的压力测试和众多的ip源(我有但我不清楚它们甚至能不能达到服务器). 故此打开issue 在此处查看关于此功能的进展

如果您想测试 请联系我以获得构建包. 此功能可能有一定的不稳定性 使用前请确保您有备用手段回滚MoeFilter对您的ipset&iptables策略所做的更改.

非紧急情况下不要强制关闭服务器 这会导致iptables无法被正确卸载

todo:

• 模块(是否)工作测试
• 多线程异步命令线程池分配情况 (需要在5ms内涌入至少到达服务器核心数量的ip以及更高的cps!)
• 策略问题

IPTables & IPSet 是硬编码的 我还不是很熟悉它们 如果您发现了语法错误或者可以改善的地方 请打开一个拉取请求. 初始化命令和卸载命令位于 OSFirewallLoader.kt.

为了避免因为iptables以及ipset消耗殆尽的问题 我们需要更高级的scheduler和自动分配其重复延迟. 这可能会在以后会进一步实施 但实际上目前mcstorm已不可用 并且我不知道能从其它地方找到更好的压力源进行测试.

插件在Linux环境下Rejoin与Ping检测无限循环

核心：waterfall-1.20-559.jar
插件版本0.15
BC核心版本 1.20
客户端版本1.8.9
问题：在玩家进入第一个Ping检测后无限循环 后面调整配置为Rejoin后也是无限循环

在快速启动模式下. 在BungeeCord注册Listener之前注入管道会导致NPE

ChunkPacket for 1.16.1: found 320 bytes extra whilst reading packet 33 (0x21)

Blocks become invisible when using the vanilla client in 1.16.1.

[Limbo] Client-side decoder error when joining limbo world (<=1.12.2)

MessageUtil v2

所有消息使用数据包和缓存并添加跨版本支持. 以达到真正高性能的目的.

Decoration cannot be serialized

How to reproduce:

MixedComponent("<aqua> <b>Test</b> <i>Test</i> <u>Test</u> <obf>Test</obf>".toComponent())

Send it to the client. The client will be disconnect:

written from json:
io.netty.handler.codec.DecoderException: com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 1 column 5

written from nbt:
Failed to decode: No matching codec found; No matching codec found; No matching codec found; List must have contents\n{color:"aqua",extra:[{},text:"Test"},{"":" "},{},{text:"Test"},{"":" "},{}],text:"Test"

Limbo captcha

在limbo内发送地图验证码以执行检查 同时增强Chcker逻辑 使其兼容多检查并发.

• 制作新的检查管理器
• 验证码绘制
• 发送
• 包装成数据包的验证码 而不是单纯的地图数据

The motd cache causes performance lag

Improve TrafficLimiter

TODO:

• Make it like that
• Apply it to bungee too.

[Limbo] Broken block item nbtdata when sending empty chunk data

缓存的潜在慢速内存泄漏风险

来自后端的Legacy颜色符号无法直接着色为MiniMessage

如题 安装了MoeFiler后 过了frist join检测 使用AjQueue的命令/queue Lobbys 进入的第一秒被提出并且玩家显示disconnected
如果要视频请加我的qq3218153361

1.20.2

与JPremium的兼容性

jpremium总是使用反射来获取InitialHandler中的uniqueid (uuid) 但MoeFilter自己的InitialHandler没有这个值
我不确定能不能修补它 我期望JPremium自己能修补这点.

如果您正在被此问题困扰 请查看最后一条comment

未来会考虑兼容mc百科的传统motd格式么？

如题，现在的component格式mc百科不支持而且不到啥时候会支持。

DosHacker Free压测方案可绕过

使用MoeFiler DosHacker Free压测方案 虽然防住了 但是服务器直接崩溃 玩家无法进入
家宽 5900x 但是在压测的时候宽带是够的 压测了一段时间会卡 然后崩溃

[Limbo] Client don't respond PacketKeepAlive when joining limbo world (>=1.16.2)

针对重复的colorize消息使用缓存

MiniMessage虽然很好玩 但处理比传统的符号还要花上不少时间

等会会尝试给已经colorized过的消息加个缓存来记录.

(Experimental) Implement Motd caching on a standalone PacketHandler.

Try to implement motd caching directly without implementing limbo. (Send motd packets directly on PacketHandler. No need to call listener is required. Even do not need to go through the InitialHandler)

TODO:

• implement it
• configurable avatar clipping. just like the original motd cache manager
• test it in a strict environment (with a large number of requests or with very little memory allocated)

LoggerManager not unload when bungeecord shutdown

[Limbo] Dimension issue

需要更多关于群戏的东西来让Limbo完全正常工作.

[MoeTranslation] How to translation `isProxyCommand` and `isCommand`

thats how it goes.
im currently having some difficulties. velocity's ChatEvent does not provide which category the message belongs to (chat, command, agent, etc..). But BungeeCord is different. BungeeCord will offer 'isProxyCommand' and 'isCommand'. so just need to play some logic games. we can then know who the audience for this message is.
although BungeeCord doesnt actually implement them either(very simple judgment. just like they build proxies do). this is extremely dependent on the current platform. implementing them requires complex processing. so im not quite sure if im worth doing those.

*: the reason this event is really hard to implement is to get the command and its permissions. because if the player doesnt have permissions. their commands will be directly send to the backend.

BotFilter compatible

Make MoeFilter pipeline compatible with BotFilter.

清理代码

我有计划清理代码 让代码变得简洁可观 就像 1ac547e 提交所做那样 试图用更少的代码实现更多的功能.

一些代码例如就像反面模式中的一些例子. 但我的主要目标仍然是上面所说.

API接口不建议进行大更改. 除非更改能够保持与之前接口的兼容性.

虽然这基本上就是 长火车 但还是仍然欢迎任何对代码简洁化或增强的拉取请求(pr)

(config) List<AbstractConfig> support
