关于 GSerialize & XPRPC

GSerialize 是基于代码生成的C#二进制序列化方案,设计目标是尽量快速的同时保证易用性

  • 支持绝大多数原生类型
  • 支持用SerializableAttribute标记的public class
  • 支持数组(一维)、List、Dictionary<K,V>等集合类型
  • 快速(比 BinaryFormatter 快一个数量级)
  • 支持 .NET Standard 2.0

XPRPC 是利用GSerial实现的一个RPC服务框架,设计目标依旧是易用且高效

  • 基于角色权限配置的安全机制
  • 服务单进程内本地部署或基于TCP连接的分布式部署,客户端/服务器代码在此两种情形下基本一致
  • 分布部署支持event夸网络传递,可选支持SSL连接,支持客户端自动重连
  • 支持双向自动代理,客户端/服务器可以通过接口互相调用

GSerialize 用法

GSerialize设计为非常易于使用的方式

var serializer = Serializer(stream); //Construct a serializer that will store data into a stream
//To serialize an object
serializer.Serialize<YourClass>(yourClassInstance);
//To deserialize an object
var yourClassInstance = serializer.Deserialize<YourClass>();

序列化原生类型,目前支持的原生类型有

  • Int16/UInt16
  • Int32/UInt32
  • Int64/UInt64
  • Byte/SByte
  • String
  • Char
  • Decimal
  • Float
  • Double
  • DateTime
  • Guid

代码示例

using var mem = new MemoryStream();
var serializer = new Serializer(mem);

UInt16 un16_1 = 123;
mem.Seek(0, SeekOrigin.Begin);
serializer.Serialize(un16_1);
mem.Seek(0, SeekOrigin.Begin);
var un16_2 = serializer.Deserialize<UInt16>();
Debug.Assert(un16_1 == un16_2);

string str1 = "good idea";
mem.Seek(0, SeekOrigin.Begin);
serializer.Serialize(str1);
mem.Seek(0, SeekOrigin.Begin);
var str2 = serializer.Deserialize<string>();
Debug.Assert(str1 == str2);

float f1 = 1.236f;
mem.Seek(0, SeekOrigin.Begin);
serializer.Serialize(f1);
mem.Seek(0, SeekOrigin.Begin);
var f2 = serializer.Deserialize<float>();
Debug.Assert(f1 == f2);

DateTime dt1 = DateTime.Now;
mem.Seek(0, SeekOrigin.Begin);
serializer.Serialize(dt1);
mem.Seek(0, SeekOrigin.Begin);
var dt2 = serializer.Deserialize<DateTime>();
Debug.Assert(dt1 == dt2);

Guid guid_1 = Guid.NewGuid();
mem.Seek(0, SeekOrigin.Begin);
serializer.Serialize(guid_1);
mem.Seek(0, SeekOrigin.Begin);
var guid_2 = serializer.Deserialize<Guid>();
Debug.Assert(guid_1 == guid_2);

自定义类型

定义自己的可序列化类型

自定义类型的字段/属性可以是以下类型

  • 原生类型
  • 泛型 List
  • 泛型 Dictionary
  • Enum
  • Nullable

代码示例

[Serializable] //附加 SerializableAttribute, 标记此类为可序列化
public class OptionalFieldUnit
{
    [NonNull] //NonNull 标记非null的字段/属性,序列化时不会检查是否为null,这能改进性能
    public string RequiredField;

    public string OptionalField;

    [NonSerialized] //NonSerialized 标记忽略字段/属性,不会被序列化
    public string IgnoredField;

    public string ReadOnlyProperty => PrivateField; //readonly 字段/属性不会被序列化

    private string PrivateField; //private 字段/属性不会被序列化
}

行为

当Serializer.Serialize/Deserialize方法被调用时,如果针对类型T的序列化代码不存在,则自动生成序列化代码并缓存在内存中,后续则直接调用生成的代码来执行序列化。

当生成类型T相关的序列化代码时,其所在Assembly中的全部Serializable标记public class皆同时生成序列化代码,且其依赖的类型相关序列化代码也会生成。

生成代码过程相对较慢,可能会消耗若干秒。客户程序可以通过调用Serializer.CacheSerialiablesInAssembly方法来预先生成某个Assembly中全部Serializable标记的public class相关序列化代码。

限制

  • 为了达到最佳性能,GSerialize.Serializer 不支持引用检测,同一个对象的每个引用都是独立存储一个拷贝,恢复时则解析成不同对象。若待序列化class中含有循环引用,则序列化过程会死循环,因此自定义类型必须保证不能出现内部成员属性/字段间的循环引用。

  • 若要检测引用,可使用GSerialize.Serializer2,同一个对象的多个引用只存储一个拷贝,恢复时还是解析成同一个对象。性能上会有少许损失(同等数据量比Serializer慢约10%,但依旧能够快BinaryFormatter一个数量级)。如果重复引用数量足够多,Serializer2可能比Serializer更快因为读写数据量更小。

  • GSerialize 不是线程安全的,从多个线程同时访问 Serializer/Serializer2 的同一个实例可能会出错。

  • 自定义类型需要支持无参数public构造器

GSerialize高性能的实现

  • 基于自定义class字段/属性的静态类型来生成代码,而非序列化时通过反射来操作
  • 通过unsafe代码来操作底层二进制数据
  • 对容器中的数据序列化时,将循环内的重复代码提取到循环外
  • 将buffer定义成class member复用,尽可能减少buffer的new操作
  • 不使用抽象,避免间接层,所有public class都是sealed的

XPRPC 用法

XPRPC 的基本结构是由一个周知的服务器管理器(由IServiceManager接口定义)管理各个发布的接口信息。 服务提供者通过ServiceRunner来发布服务。客户端通过ServiceResolver来解析需要的服务并调用。

IServiceManager

该服务由ServiceManagerImpl实现,提供客户端身份验证,登记服务信息,查询服务信息及服务健康检测(TODO)等功能。 LocalManagerRunner用于本地发布 IServiceManager 服务,TcpManagerRunner用于跨网络发布 IServiceManager 服务。

ILogger

该服务作为系统的基础服务,随XPRPC一起提供,用于输出日志,目前支持Console、Debug、文件系统三种输出目标。

发布服务

以网络服务发布为例

  • 发布 IServiceManager,必须是周知的地址/端口
var logger = BuilderLogger(); 
var descManager = new ServiceDescriptor
{
    Name = "service_manager",
    Description = "服务治理",
    ServiceHost = "localhost",
    ServicePort = 3324, //服务器主机名及端口为client周知
    AccessToken = "AnyClient"
};
using var managerRunner = TcpManagerRunner.Instance;
managerRunner.Logger = logger; //需要一个logger作为基础服务
var config = AccessConfig.FromJson(ManagerConfigJson);
managerRunner.Config(config); //配置IServiceManager的安全权限
managerRunner.Start(descManager, sslCertificate: null); //发布服务, sslCertificate若不为null则使用此证书建立SSL
  • 发布 ILogger服务,供其他服务使用 ServiceRunner 用于发布一个除IServiceManager之外的服务,其子类 LocalServiceRunner、TcpServiceRunner分别用于发布本地服务和网络服务。
var loggerDescriptor = new ServiceDescriptor
{
    Name = "logger",
    Description = "日志服务",
    ServicePort = 0, //IServiceManager之外的服务端口任意
};
using var loggerRunner = new TcpServiceRunner<ILogger>(
    service: logger,
    descriptor: loggerDescriptor, 
    holdService: false, 
    logger: logger, 
    sslCertificate: null);
//发布服务,发布者的clientID必须在IServiceManager中配置有发布服务的权限
loggerRunner.Start(descManager, clientID: "logger_provider",secretKey: "Dx90et54");
  • 发布其他服务 类似上面的ILogger服务的发布,若不在ILogger服务的发布进程内,则logger要使用远程获取的ILogger代理

客户端使用服务

ServiceResolver类用于解析服务,其子类LocalServiceResolver、TcpServiceResolver分别用于解析本地和网络服务。

//构建resolver,必须保证访问权限正确
using var resolver = new TcpServiceResolver(descManager, clientID: "logger_client", secretKey: "02384Je5");
//解析服务,获取远程服务的本地代理,同样需要保证拥有对应的服务的访问权限
var remoteLogger = resolver.GetService<ILogger>("logger");
//RPC调用服务
remoteLogger.Info(tag: "Tcp Test", message: "remote log message.");

Distribution of Source Form All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Software is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt to alter or restrict the recipients' rights in the Source Code Form. 3.2. Distribution of Executable Form If You distribute Covered Software in Executable Form then: (a) such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and (b) You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients' rights in the Source Code Form under this License. 3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies. 3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction. 4. Inability to Comply Due to Statute or Regulation --------------------------------------------------- If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Termination -------------- 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice. 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination. ************************************************************************ * * * 6.
