简介

应用程序管理模块提供了应用程序的启动及其进程的生命周期管理的功能。属于Ability管理的上一级管理目录。一下内容以v3.1-Release版进行分析。

类间关系及关键类介绍

类图

OpenHarmony——应用程序管理(AppManager)模块源码解析-开源基础软件社区

AppMgrServiceInner及AppRuningRecord是应用管理服务核心类。应用管理服务进程内的各类事件及任务通过AMSEventHandler投递到主线程,并调用AppMgrServiceInner的方法执行。

AppMgrServiceInner中含有AppRunningManager的实例,AppRunningManager中以map表的形式包含所有的AppRunningRecord。每一个AppRunningRecord对应着一个应用进程(即上述类图中MainThread所在的进程),AppRunningRecord通过AppLifeCycleDeal管理所对应的应用进程的生命周期。

MainThread及OHOSApplication是应用进程的核心类。应用进程内的各类事件及任务通过MainThread中mainHandler_投递到主线程并调用MainThread中的方法执行。OHOSApplication中包含应用进程的上下文,可以通过abilityRecordMgr中的AbilityThread对进程内的各Ability线程进行调用。

应用进程与服务管理进程之间,通过IDL实现进程间调用。IAppSchedule, IAppMgr, IAmsMgr是进程间调用的接口类。

服务管理进程还可以通过socket与AppSpawanServer通信。AppSpawanServer内可进行系统调用。

关键类介绍
类名 功能简介
MainThread 应用程序主线程类,负责进程内各类事件及任务的执行,并实现了IPC调用的各接口。
OHOSApplication 包含应用进程的上下文环境,负责管理及调用该进程下的各Ability。
abilityRecordMgr 包含属于这个应用进程的所有AbilityLocalRecord的集合,其中AbilityLocalRecord中又封装了AbilityThread。由此实现应用进程对各Ability线程的调用
IAppSchedule 应用进程提供的进程间的调用接口。可通过此接口实现对应用进程生命周期的调用。
AppMgrService 应用管理服务主线程类。实现了IPC调用的IAppMgr接口。并通过AMSEventHandler将进程内各类事件及任务投递到主线程。
AppMgrServiceInner 应用管理服务内部的主线程类,通过AMSEventHandler投递到主线程的各事件及任务,基本上都是调用AppMgrServiceInner的方法进行执行。
AmsMgrScheduler 实现了IPC调用的IAmsMgr接口。并通过AMSEventHandler将各类事件及任务投递到主线程。
AppRunningManager 所有应用进程的AppRunningRecord的合集,以Map表的形式存在于该类
AppRuningRecord 存储了应用进程的各种信息,可对应用进程进行调度管理。
AppLifeCycleDeal 对应用进程的生命周期进行调度
ModuleRunningRecord 对应用进程的Ability进行管理调度
IAppMgr 应用管理服务提供的进程间的调用接口。可通过此接口实现对管理进程的调用。
IAmsMgr 应用管理服务提供的进程间的调用接口。可通过此接口实现对管理进程的调用。主要的调用方是Ability模块。

应用程序启动的时序图

当加载某个Ability时,会启动该Ability所属的应用进程。以此为例分析应用进程的启动过程。

源码分析

限于篇幅,每个调用函数只摘抄关键语句。

1. ability模块通过 IAmsMgr的接口调用 AmsMgrScheduler的LoadAbility

foundation\aafwk\standard\services\appmgr\src\ams_mgr_scheduler.cpp

void AmsMgrScheduler::LoadAbility(const sptr<IRemoteObject> &token, const sptr<IRemoteObject> &preToken,
    const std::shared_ptr<AbilityInfo> &abilityInfo, const std::shared_ptr<ApplicationInfo> &appInfo,
    const std::shared_ptr<AAFwk::Want> &want)
{
  
    std::function<void()> loadAbilityFunc =
        std::bind(&AppMgrServiceInner::LoadAbility, amsMgrServiceInner_, token, preToken, abilityInfo, appInfo, want);

    amsHandler_->PostTask(loadAbilityFunc, TASK_LOAD_ABILITY);    // 通过amsHandler发送loadAbilityFunc任务给AppMgrService的主线程
}
2. AppMgrService的主线程调用 app_mgr_service_inner.cpp中的 LoadAbility

foundation\aafwk\standard\services\appmgr\src\app_mgr_service_inner.cpp

void AppMgrServiceInner::LoadAbility(const sptr<IRemoteObject> &token, const sptr<IRemoteObject> &preToken,
    const std::shared_ptr<AbilityInfo> &abilityInfo, const std::shared_ptr<ApplicationInfo> &appInfo,
    const std::shared_ptr<AAFwk::Want> &want)
{
   
    std::string processName;
    MakeProcessName(processName, abilityInfo, appInfo, hapModuleInfo);     //根据ability及hap包信息构建应用程序进程名
    HILOG_INFO("processName = [%{public}s]", processName.c_str());

    auto appRecord =
        appRunningManager_->CheckAppRunningRecordIsExist(appInfo->name, processName, appInfo->uid, bundleInfo); //根据应用程序进程名检查该appRecord是否存在,如果appRecord已经存在,说明该应该程序是启动中的。
    if (!appRecord) {
        appRecord =
            CreateAppRunningRecord(token, preToken, appInfo, abilityInfo,
                processName, bundleInfo, hapModuleInfo, want); //该appRecord不存在的情况下,创建appRecord
        if (!appRecord) {
            HILOG_ERROR("CreateAppRunningRecord failed, appRecord is nullptr");
            return;
        }
        bool isColdStart = want == nullptr ? false : want->GetBoolParam("coldStart", false);
        StartProcess(abilityInfo->applicationName, processName, isColdStart, appRecord,
            appInfo->uid, appInfo->bundleName);  //调用同文件中的StartProcess启动该应用程序进程。
    } else {
        StartAbility(token, preToken, abilityInfo, appRecord, hapModuleInfo, want); 
    }
    PerfProfile::GetInstance().SetAbilityLoadEndTime(GetTickCount());
    PerfProfile::GetInstance().Dump();
    PerfProfile::GetInstance().Reset();
}
void AppMgrServiceInner::StartProcess(const std::string &appName, const std::string &processName, bool coldStart,
    const std::shared_ptr<AppRunningRecord> &appRecord, const int uid, const std::string &bundleName)
{
 
    PerfProfile::GetInstance().SetAppForkStartTime(GetTickCount());
    pid_t pid = 0;
    ErrCode errCode = remoteClientManager_->GetSpawnClient()->StartProcess(startMsg, pid); //通过appSpawanSocket与AppSpwanSever进行socket通信,发送启动进程的消息给AppSpawnServer, AppSpawnServer启动后的进程信息等会通过startMsg,pid返回。
    if (FAILED(errCode)) {
        HILOG_ERROR("failed to spawn new app process, errCode %{public}08x", errCode);
        appRunningManager_->RemoveAppRunningRecordById(appRecord->GetRecordId());
        return;
    }
    HILOG_INFO("newPid:%{public}d uid:%{public}d", pid, startMsg.uid);
    appRecord->GetPriorityObject()->SetPid(pid);  // 设置appRecord关联的应用进程的pid
    appRecord->SetUid(startMsg.uid);              // 设置appRecord关联的Uid
    appRecord->SetStartMsg(startMsg);
    appRecord->SetAppMgrServiceInner(weak_from_this());
    OnAppStateChanged(appRecord, ApplicationState::APP_STATE_CREATE);
    AddAppToRecentList(appName, appRecord->GetProcessName(), pid, appRecord->GetRecordId());
    OnProcessCreated(appRecord);
    PerfProfile::GetInstance().SetAppForkEndTime(GetTickCount());
}
3. appSpawanServer通过消息队列的方式处理接收到的消息,并启动相应的应用进程。

base\startup\appspawn_standard\src\appspawn_serrver.cpp

bool AppSpawnServer::ServerMain(char *longProcName, int64_t longProcNameLen)
{
   
    while (isRunning_) {
      
        std::unique_ptr<AppSpawnMsgPeer> msg = std::move(appQueue_.front());
        appQueue_.pop();                                                    //按照先进先出的原则弹出一条消息  
        int connectFd = msg->GetConnectFd();                                
        ClientSocket::AppProperty *appProperty = msg->GetMsg();             
        pid_t pid = 0;
        int ret = StartApp(longProcName, longProcNameLen, appProperty, connectFd, pid);    //启动相应的进程
       
    QuickExitMain();
    return false;
}
int AppSpawnServer::StartApp(char *longProcName, int64_t longProcNameLen,
    ClientSocket::AppProperty *appProperty, int connectFd, pid_t &pid)
{
    if (!CheckAppProperty(appProperty)) {
        return -EINVAL;
    }
    int32_t fd[FDLEN2] = {FD_INIT_VALUE, FD_INIT_VALUE};
    int32_t buff = 0;
    if (pipe(fd) == -1) {
        HiLog::Error(LABEL, "create pipe fail, errno = %{public}d", errno);
        return ERR_PIPE_FAIL;
    }

    InstallSigHandler();
    pid = fork();                   //通过系统调用创建新进程
    if (pid < 0) {
        HiLog::Error(LABEL, "AppSpawnServer::Failed to fork new process, errno = %{public}d", errno);
        close(fd[0]);
        close(fd[1]);
        return -errno;
    } else if (pid == 0) {
        SpecialHandle(appProperty);
        // close socket connection and peer socket in child process
        if (socket_ != NULL) {
            socket_->CloseConnection(connectFd);
            socket_->CloseServerMonitor();
        }
        close(fd[0]); // close read fd
        ClearEnvironment();
        UninstallSigHandler();
        SetAppAccessToken(appProperty);       
        if ((appProperty->flags == ClientSocket::APPSPAWN_COLD_BOOT) &&
            OHOS::system::GetBoolParameter("appspawn.cold.boot", false)) {
            DoColdStartApp(appProperty, fd[1]);
        } else {
            SetAppProcProperty(appProperty, longProcName, longProcNameLen, fd[1]);  //在新进程执行相应的应用程序逻辑
        }
        _exit(0);
    }
    read(fd[0], &buff, sizeof(buff)); // wait child process resutl
    close(fd[0]);
    close(fd[1]);

    HiLog::Info(LABEL, "child process init %{public}s", (buff == ERR_OK) ? "success" : "fail");
    return (buff == ERR_OK) ? 0 : buff;
}
bool AppSpawnServer::SetAppProcProperty(const ClientSocket::AppProperty *appProperty, char *longProcName,
    int64_t longProcNameLen, const int32_t fd)
{
   
#ifdef NWEB_SPAWN
    using FuncType = void (*)(const char *cmd);
    FuncType funcNWebRenderMain = reinterpret_cast<FuncType>(dlsym(nwebHandle, "NWebRenderMain"));
    if (funcNWebRenderMain == nullptr) {
        HiLog::Error(LABEL, "nwebspawn dlsym ERROR=%{public}s", dlerror());
        return false;
    }
    funcNWebRenderMain(appProperty->renderCmd);
#else
    AppExecFwk::MainThread::Start();                                   //启动应用程序主线程
#endif

    HiLog::Error(LABEL, "Failed to start process, pid = %{public}d", getpid());
    return false;
}
4. 应用程序主线程(FrameWork层)
