Bug 1814856 - Collapse QuotaManager::mShutdownStarted on gShutdown. r=dom-storage-reviewers,janv

void QuotaManager::RecordQuotaManagerShutdownStep(

    const nsACString& aStepDescription) {

  // Callable on any thread.

  MOZ_ASSERT(mShutdownStarted);

  MOZ_ASSERT(IsShuttingDown());

  RecordShutdownStep(Nothing{}, aStepDescription);

}

  // Define some local helper functions

  auto flagShutdownStarted = [this]() {

    mShutdownStartedAt.init(TimeStamp::NowLoRes());

    // Setting this flag prevents the service from being recreated and prevents

    // further storages from being created.

    // XXX: Harmonize QM shutdown flags, see bug 1726714

    gShutdown = true;

    // StopIdleMaintenance used to happen before mShutdownStarted is set true

    // but it is just an internal flag for the recording of shutdown steps

    // and not evaluated elsewhere.

    mShutdownStartedAt.init(TimeStamp::NowLoRes());

    mShutdownStarted = true;
