huatuo

huatuo是一个特性完整、零成本、高性能、低内存的近乎完美的Unity全平台原生c#热更方案。

huatuo扩充了il2cpp的代码，使它由纯AOT runtime变成‘AOT+Interpreter’ 混合runtime，进而原生支持动态加载assembly，使得基于il2cpp backend打包的游戏不仅能在Android平台，也能在IOS、Consoles等限制了JIT的平台上高效地以AOT+interpreter混合模式执行。从底层彻底支持了热更新。

huatuo开创性地实现了 differential hybrid dll 技术====。即可以对AOT dll任意增删改，huatuo会智能地让变化或者新增的类和函数以interpreter模式运行，但未改动的类和函数以AOT方式运行，让热更新的游戏逻辑的运行性能基本达到原生AOT的水平。

特性

• 特性完整。 近乎完整实现了ECMA-335规范，除了 下文中"限制和注意事项" 之外的特性都支持。
• 零学习和使用成本。 huatuo将纯AOT runtime增强为完整的runtime，使得热更新代码与AOT代码无缝工作。脚本类与AOT类在同一个运行时内，可以随意写继承、反射、多线程(volatile、ThreadStatic、Task、async)之类的代码。不需要额外写任何特殊代码、没有代码生成，也没有什么特殊限制。
• 执行高效。实现了一个极其高效的寄存器解释器，所有指标都大幅优于其他热更新方案。性能测试报告
• 内存高效。 热更新脚本中定义的类跟普通c#类占用一样的内存空间，远优于其他热更新方案。内存占用报告
• 原生支持hotfix修复AOT部分代码。几乎不增加任何开发和运行开销。
• 开创性地实现了 differential hybrid dll 技术。即可以将某个热更新dll先AOT形式打包，后面可以对该dll任意增删改，huatuo会智能地让变化或者新增的类和函数以interpreter模式运行，但未改动的类和函数以AOT方式运行。这意味着热更新的游戏逻辑的运行性能将接近原生AOT的水平。

工作原理

huatuo从mono的hybrid mode execution技术中得到启发，为unity的il2cpp之类的AOT runtime额外提供了interpreter模块，将它们由纯AOT运行时改造为"AOT + Interpreter"混合运行方式。

更具体地说，huatuo做了以下几点工作：

• 实现了一个高效的元数据(dll)解析库
• 改造了元数据管理模块，实现了元数据的动态注册
• 实现了一个IL指令集到自定义的寄存器指令集的compiler
• 实现了一个高效的寄存器解释器
• 额外提供大量的instinct函数，提升解释器性能
• 提供hotfix AOT的支持

与其他流行的c#热更新方案的区别

本质比较

huatuo是原生的c#热更新方案。通俗地说，il2cpp相当于mono的aot模块，huatuo相当于mono的interpreter模块，两者合一成为完整mono。huatuo使得il2cpp变成一个全功能的runtime，原生（即通过System.Reflection.Assembly.Load）支持动态加载dll，从而支持ios平台的热更新。

正因为huatuo是原生runtime级别实现，热更新部分的类型与主工程AOT部分类型是完全等价并且无缝统一的。可以随意调用、继承、反射、多线程，不需要生成代码或者写适配器。

其他热更新方案则是独立vm，与il2cpp的关系本质上相当于mono中嵌入lua的关系。因此类型系统不统一，为了让热更新类型能够继承AOT部分类型，需要写适配器，并且解释器中的类型不能为主工程的类型系统所识别。特性不完整、开发麻烦、运行效率低下。

实际使用体验或者特性比较

• huatuo学习和使用成本几乎为零。huatuo让il2cpp变成全功能的runtime，学习和使用成本几乎为零，几乎零侵入性。而其他方案则有大量的坑和需要规避的规则，学习和使用成本，需要对原项目作大量改造。
• huatuo可以使用所有c#的特性。而其他方案往往有大量的限制。
• huatuo中可以直接支持使用和继承主工程中的类型。其他方案要写适配器或者生成代码。
• huatuo中热更新部分元数据与AOT元数据无缝统一。像反射代码能够正常工作的，AOT部分也可以通过标准Reflection接口创建出热更新对象。其他方案做不到。
• huatuo对多线程支持良好。像多线程、ThreadStatic、async等等特性都是huatuo直接支持，其他方案除了async特性外均难以支持。
• huatuo中Unity工作流与原生几乎完全相同。huatuo中热更新MonoBehaviour可以直接挂载在热更新资源上，并且正确工作。其他方案不行。
• huatuo兼容性极高。各种第三方库只要在il2cpp下能工作，在huatuo下也能正常工作。其他方案往往要大量魔改源码。
• huatuo内存效率极高。huatuo中热更新类型与主工程的AOT类型完全等价，占用一样多的空间。其他方案的同等类型则是假类型，不仅不能被runtime识别，还多占了数倍空间。
• huatuo执行效率高。huatuo中热更新部分与主工程AOT部分交互属于il2cpp内部交互，效率极高。而其他方案则是独立虚拟机与il2cpp之间的效率，不仅交互麻烦还效率低下。

稳定性状况

=== 庆祝于 2021.6.7 第一款使用huatuo的android和iOS双端休闲游戏正式上线 ===，7月份还有几款中重游戏上线或者对外测试。

技术评估上目前稳定性处于Beta版本。由于huatuo技术原理的先进性，bug本质上不多，稳定得非常快。

• 目前PC、Android、iOS 已跑通所有单元测试，可稳定体验使用。
• 测试了游戏常用库和框架的兼容性，兼容性良好。只要能在il2cpp backend下工作的库都可以在huatuo下正常工作。甚至那些与il2cpp因为AOT问题不兼容的库，现在因为huatuo对il2cpp的能力扩充，反而可以正常运行了。具体参见 兼容性报告
• 已经有几十个大中型游戏项目较完整地接入huatuo，并且其中一些在紧锣密鼓作上线前测试。具体参见收集的一些 完整接入的商业项目列表

RoadMap

huatuo虽然与il2cpp相关，但绝大多数核心代码独立于il2cpp，很容易移植（预计一个月）到其他不支持AOT+Interpreter的CLR平台。无论unity如何版本变迁，哪怕废弃了il2cpp改用.net 6+，huatuo会持续跟进，稳定地提供跨平台的CLR热更新服务，直至某天.net官方直接支持AOT+Interpreter，则huatuo完成其历史使命。

• 支持Unity 2019、2020和2021系列版本 (2022.6 -)
• 支持32位 (2022.6 - 2022.7)
• 指令优化，编译后指令数减少到原来1/4-1/2，基础指令和大多数对象模型指令有100%-300%的性能提升。 (2022.7 -)
• 支持增量式gc (2022.8 -)

实现IDisposable接口，通过Using定义，作用域结束后，不会主动调用Dispose函数

测试环境

Untiy 2017.3.7f1c1，PC，IL2CPP, NET4.x

测试代码

public class HotfixMain
{
    public static void Init()
    {
        using (var myClass = new MyClass())
        {
            Debug.Log("using content.");
        }
    }
}

public class MyClass : IDisposable
{
    public void Dispose()
    {
        Debug.Log("My class dispose.");
    }
} 

预期结果

using作用域范围结束后，打印"My class dispose"

代码文件

using_case.zip

TaskCompletionSource<T>有问题

var tcs1 = new TaskCompletionSource();
public class VerifyTest
{
public string s;
public string Address;
}
上面的代码在AOT中使用

` public static async void Enter()
{
Debug.Log("Send---a");
await Send();
}
public static async Task Send()
{
var tcs = new TaskCompletionSource();
Debug.Log("Send---b");

}`

VerifyTest声明在AOT的代码中，TaskCompletionSource已经在AOT中注册，调用Enter时会出错：MissingMethodException:MethodPointerNotImplement System.Void System.Threading.Tasks.TaskCompletionSource'1[t_RecursiveFallbackBytes]:ctor（）

继承泛型类闪退，但是将泛型类放到热更层就正常

AOT代码

public interface IStateOwner
{
     Task TranslateState<TState>(object[] args);
}
public abstract class State <TOwner> where TOwner: IStateOwner
{
    public abstract Task OnEnter();

}

热更层代码

public class GameManager: IStateOwner
{
    public Task TranslateState<TState>(object[] args)
    {
        throw new NotImplementedException();
    }
}
public class GameState_Version : State<GameManager>
{
    public override  Task OnEnter()
    {
        Debug.Log("GameState_Version->OnEnter");
        return null;
    }
}

请问这个新版huatuo和hybridclr是什么关系？为什么内容一模一样？

我很纳闷，为什么两个项目内容一模一样

使用全热更状态下的ETTask测试异常

将ETTask全放入到热更程序集种，使用如下代码测试，工作异常

        public static void Start()
        {
            AsyncMethod().Coroutine();
        }

        static async ETTask AsyncMethod()
        {
            Debug.Log("Begin");
            await ETTask.CompletedTask;
            Debug.Log("End");
        }

注释掉Coroutine方法中的InnerCoroutine调用后可正常工作

        [DebuggerHidden]
        private async ETVoid InnerCoroutine()
        {
            await this;
        }

        [DebuggerHidden]
        public void Coroutine()
        {
            InnerCoroutine().Coroutine();
        }

经打断点调试发现是libil2cpp\huatuo\transform.cpp 3895行的断言引起的，此时size为24，GetTypeValueSize得到的size为8
初步怀疑是是由C#方法InnerCoroutine引起的该方法await的是一个ETTask返回的是一个async ETvoid

	PopStack();
	PushStackByType(&objKlass->byval_arg);
	IL2CPP_ASSERT(size == GetTypeValueSize(&objKlass->byval_arg));
	InsertMemoryBarrier();
	ResetPrefixFlags();
	ip += 5;
	continue;

ETTask的源码文件地址https://github.com/egametang/ET/tree/master/Unity/Assets/ThirdParty/ETTask
将整个ETTask文件夹放入热更程序集复制上述代码RefTypes中加入Queue泛型(印象中示例工程没加Queue)即可测试。

Task<T>崩溃的例子

首先在AOT定义AckMsg和IMessageTest接口，并添加泛型接口的引用

public struct AckMsg<T>
{
    public bool cancel;
    public T msg;

    public AckMsg(T msg, bool cancel)
    {
        this.msg = msg;
        this.cancel = cancel;
    }
}
public interface IMessageTest
{
    int CalculateSize();
}
public interface IMessageTest<T> : IMessageTest where T : IMessageTest<T>
{
    void MergeFrom(T message);
}
TaskAwaiter aw = default;
var c11 = new AsyncTaskMethodBuilder<AckMsg<IMessageTest>>();
c11.Start(ref stateMachine);
c11.AwaitUnsafeOnCompleted(ref aw, ref stateMachine);
c11.AwaitOnCompleted(ref aw, ref stateMachine);
c11.SetException(null);
c11.SetResult(default);
bl = aw.IsCompleted;

TaskAwaiter<AckMsg<IMessageTest>> awAckMsg = default;
var c12 = new AsyncVoidMethodBuilder();
var c12B = AsyncVoidMethodBuilder.Create();
c12.Start(ref stateMachine);
c12.AwaitUnsafeOnCompleted(ref awAckMsg, ref stateMachine);
c12.SetException(null);
c12.SetResult();

然后在热更层定义类VerifyACKTest继承IMessageTest

public class VerifyACKTest: IMessageTest<VerifyACKTest>
{
    public void MergeFrom(VerifyACKTest message)
    {
    }

    public int CalculateSize()
    {
        //throw new System.NotImplementedException();
        return 0;
    }
}

最后热更层调用Enter()方法就会崩溃

public static async void Enter()
{
    await Send<VerifyACKTest>();
}
public static async Task<AckMsg<T>> Send<T>()
{
    var tcs = new TaskCompletionSource<T>();
    Debug.Log("Send---b");
    return new AckMsg<T>(default, true);
}

引入ECS后打包，不管用没用，启动直接崩溃。

不支持git submodule

目前的目录结构不支持git submodule的方式，不利于管理，每次更新都需要手动copy.
能不能调整下目录结构。

会支持32位吗

使用一个插件的时候 如果事件类型是Enum启动后会报错

Unity 2021.3.4
插件: https://github.com/ls9512/UEvent

在热更代码里 使用Enum类型的事件

[Listen(GameEvent.Test1)] //GameEvent是Enum
void OnEventMessage4()
{
    Debug.Log("-----------------收到事件4");
}

启动报错

试了string类型 没问题

是否支持MacOS的Runtime？是否有支持计划？

是否支持像 InjectFix 这种形式的HotFix

看示例代码貌似跟 ILRuntime 之类的使用方式类似（实现不同），但是 InjectFix 之类的能够 Patch 原有 AOT 代码的模式才是更有价值的，请问这种模式是否支持，如果不支持的话将来是否有计划提供支持?
InjectFix 的 HotFix 原理是对 IL 插桩, 如果 huatuo 不采用插桩而是替换 meta 的话，只会对反射调用的函数生效吧。

2021.3 Demo Project crash.

在扩展方法函数参数Action回调中，传入扩展方法，导致程序直接崩溃

[Bug] 函数 out byte 导致的 bug

void Hello(out byte c)
{
    c = 1;
}

void Awake()
{
    byte c;
    Hello(out c);
    for (int i = 0; i < c; i++)
    {
        Debug.Log("AAAAAAAAAAAA " + i);
    }
}

就这段代码，放 Hotfix 去跑，可能出现的结果是：打印出无数行
注意：另一个问题是，有时候 c 打印出来的确是 1，但是却也被循环了多次
（猜测：所以可能问题出在于 int 和 byte 的比较上）

Vector3使用问题

public static UnityEngine.Vector3 Func(bool b)
{
    var v = new UnityEngine.Vector3(1, 2);
    if (b)
    {
        v = new UnityEngine.Vector3(1, 2, 3);
    }

    return v;
}

libil2cpp/huatuo/transform/Transform.cpp 的第2622行 IL2CPP_ASSERT(evalStackTop >= 4); 会出问题

Task<T>的泛型方法调用失败

AOT部分

public struct AckMsg<T>
{

    public T msg;

    public AckMsg(T msg, bool cancel)
    {
        this.msg = msg;
        this.cancel = cancel;
    }
}
public class RcvMsgTest

    public int id;

}
public static async Task<AckMsg<T>> RefTypeAddTask<T>()

    var tcs = new TaskCompletionSource<T>();
    Debug.Log("Send---b");
    var task = tcs.Task;
    await task;
    return new AckMsg<T>((T)tcs.Task.Result, false);
}

热更新部分调用Enter方法，奇怪的是我将Send2函数内容放到Send方法里面就正常

public static async void Enter()
{
    await Send<RcvMsgTest>();
}
public static async Task<AckMsg<T>> Send<T>()
{
    return await Send2<T>();
}

public static async Task<AckMsg<T>> Send2<T>()
{
    var tcs = new TaskCompletionSource<T>();
    var task = tcs.Task;
    await task;
    return new AckMsg<T>((T) tcs.Task.Result, false);
}

public class B2
{
    public Dictionary<string, string> Dict { get; set; }
}

public static void Test5()
{
    C3 a;
    a.F = 123;
    a.V = new Vector3(4, 5, 6);
    var pos = a.V;
    pos.x += 111;
}

public struct C3
{
    public float F;
    public Vector3 V;
}

}

使用Stream的Write方法有问题

public class CircularBufferTest : Stream
{

    public override bool CanRead { get; }
    public override bool CanSeek { get; }
    public override bool CanWrite { get; }
    public override long Length { get; }
    public override long Position { get; set; }
    
    
    public override void Flush()
    {
        throw new NotImplementedException();
    }


    public override int Read(byte[] buffer, int offset, int count)
    {
        throw new NotImplementedException();
    }

    public override long Seek(long offset, SeekOrigin origin)
    {
        throw new NotImplementedException();
    }

    public override void SetLength(long value)
    {
        throw new NotImplementedException();
    }
    public override void Write(byte[] buffer, int offset, int count)
    {
        
    }

    public void Write(int l)
    {
        byte[] s_Cached = new byte[4];
        s_Cached[0] = (byte)(l >> 0);
        s_Cached[1] = (byte)(l >> 8);
        s_Cached[2] = (byte)(l >> 16);
        s_Cached[3] = (byte)(l >> 24);
        Write(s_Cached, 0, 4);
    }
}

public static void CircularBufferTest()
{
    var capacity = 1024 * 512;
    CircularBufferTest m_SendBuffer = new CircularBufferTest();
    var msgLen = 1;
    m_SendBuffer.Write(msgLen);
}

属性字段在最上面定义时，调用write方法时会卡死
但是将上面定义的属性字段放到Plush()方法下面时，会报NotImplementedException:The method or operation is not implemented

catch代码块不执行

using System;
using System.Collections.Generic;

namespace CSharp
{
public struct A
{
public int i;
}

public class Main
{
    public static void Entry()
    {
        try
        {
            Console.WriteLine("CSharp.Main.Entry Fix");
            
            // case 1 正常，catch里的逻辑正常执行
            // throw new MissingMethodException();
            
            // case 2
            var list = new List<A>(); // 这里应该报异常，然后执行catch里面的逻辑，测试结果是catch里的逻辑没有执行
            list.Add(new A());
            var a = new A();
            Console.WriteLine(a);
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
        }
    }
}

}

Is this from Unity source code?

应该是执行.bat后 build settings 界面提示 il2cpp is not installed

另外的原来的项目是好的
trial 示例项目：

在手机端System.Reflection.Assembly.Load(dllBytes.bytes); 不好使，报错could not load type system.data.dataset from assembly system.data

type load Exception: could not load type system.data.dataset from assembly system.data。这个该怎么解决呢。。farmwork4.0

一个崩溃bug（Coroutine 或 ?.Invoke 相关）

    public event Action OnPerSecond;
    void OnEnable()
    {
        StartCoroutine(this.KeepUpdate());
    }

    IEnumerator KeepUpdate()
    {
        while (true)
        {
            yield return new WaitForSeconds(1f);
            try
            {
                this.OnPerSecond?.Invoke();
            }
            catch (Exception ex)
            {
                Debug.LogException(ex);
            }
        }
    }

crash with in/out keyword in method param

public void PreSolve(Contact contact, in Manifold oldManifold)
{
}

请问作者这个支持xamarin吗？

如题，我有几个xamarin的程序想使热更新功能不知道你的这个框架是否支持呢？请指教，谢谢。
