gyb-e改造说明

1.用户采用(机构ID,用户编号)识别

端点ID扩展为2个32位整数,通常只用低32位,只有对于用户,高32位机构ID表示用户编码域。

废除common.h中的以下宏:

/*#define ORGID_IN_USERSERIAL(u) (u/10000)#define ORGMINUSERSERIAL(u) (u*10000)#define ORGMAXUSERSERIAL(u) (u*10000 + 9999)#define GETORGID(t,id) (t==1 ? id : ORGID_IN_USERSERIAL(id))*/

1.1一般规则

。目标为用户的消息都要设置机构ID。采用的方法为:msg->SetDest(2,用户编号,机构ID);
。所有参数为用户编号的函数都要增加一个orgid参数.
。协议中涉及用户的都需要增加用户机构

1.2数据库修改

。tb_multitalk_member 增加orgid

ALTER TABLE tb_multitalk_member ADD COLUMN orgid INT COMMENT '机构ID' AFTER talk_id;

1.3协议修改

已明确修改的协议有

521-Request:请求行集增加列orgid.表示用户的机构ID，作为第一列。返回的确认消息的行集增加orgid列。
540-Request需要增加参数obj_h_id,表示对象ID的高字，可缺省。
515-Indication:增加参数orgid.表示登录用户的机构ID。    
538-Request:请求行集增加orgid列

后续修改注意这些协议的变化。

1.4todo

未实现的有：

。用户编号生成的逻辑需要修改，每个机构的内部用户编号从1开始，新建用户时取当前该机构最大编号+1作为新用户的内部编号.

2.rto_im实现

rto_im插件实现的主要代码如下:

int CImRto::CheckValid() {    parent::CheckValid();        router_->RegisterRouteHandler(dynamic_cast<IRouteHandler*>(this)); ///< 注册路由处理器    return 0;        }////////////////////////////////////////////////////////////////////////////////int CImRto::HandleInput(CWrappedMsg<> *pwm,int &action,int &break_flag) {    CMsg *msg = pwm->msg;    int dest_t;    unsigned long dest_id_hi,dest_id_lo;    msg->GetDest(dest_t,dest_id_lo,&dest_id_hi);    if (dest_t!=PT_ORG_USER) ///< 本插件只处理目标为用户的消息的路由        return 0;        ///< 处理逻辑:    ///< 如果用户在线,    ///<  如果是登录在本服务器,则直接在本机转发;否则,交给上级路由,    ///< 如果用户不在线,    ///< 根据消息是否可靠决定是否保存在用户待办事宜中.

.检测和处理平台服务器断开

.路由消息

6.IMemData

IMemData是合并了原本地和平台内存数据库的访问接口(IAP,IDAP)，应用可以选用不同的实现，如Berkeley DB和MySQL。

合并首先要统一内存对象的定义(用户,机构,服务器等).
合并时:
.IAP对应到Berkeley DB的实现(md_mdb),IDAP对应到mysql的实现(md_mysql)
.IAP,IDAP同时有的方法，语义相同,原型不同：可以同时保留,以后再清理
.IAP，IDAP只有一个实现的：如IAP实现,则需要在md_mysql中实现该方法.对于未实现的方法,统一用assert(0)表示不支持.

如对于IMemData的
virtual int BroadcastMsgToUsers(CMsg* msg, LJUSERLIST& user_list) = 0;

来自ap的BroadcastMsgToUsers。
如果需要支持mysql，则需要实现CMemDataMySQL的该方法.

CMemDataBDB::BroadcastMsgToUsers继承自CAPPlugin的实现方法.

int CAPPlugin::BroadcastMsgToUsers(CMsg* msg, LJUSERLIST& user_list){try {CWrappedMsg<> *pwm = new CWrappedMsg<>;pwm->msg = msg;MEM_USER_KEY user_key;MEM_USER_DATA* user_data;DBC* user_dbc;LJUSERLIST::iterator user_iter = user_list.begin();for(; user_iter != user_list.end(); user_iter++){user_key.user_serial_ = *user_iter;if(user_db_->Query(&user_key, sizeof(MEM_USER_KEY), (void**)&user_data, &user_dbc, MEM_LOCATE_PK) == 0){if(user_data->svr_id_ == self_->GetServerID())  //是在本地登陆的 {if(msg->GetMsgAttr()&EXTEND1_MASK)  //用户还没准备就绪也需要发送{pwm->connid.push_back(user_data->handle_);}else{if(user_data->is_ready_)  //准备就绪才发送{pwm->connid.push_back(user_data->handle_);}}}}user_db_->CloseQuery(&user_dbc);}//发送if(pwm->connid.size() > 0) {SendMsg(pwm);return 0;}//没有发送时，需要释放pwm，会自动释放msgdelete pwm;} catch(...) {throw PluginException(CE_EXCEPTION,"CMemDataMySQL::CMemDataMySQL::BroadcastMsgToUsers",SOURCEINFO);}return -1;}

CMemDataMySQL的BroadcastMsgToUsers实现。
