Golang如何保证被另一个Goroutine访问时在Goroutine中完成数据

嗨，大家好，我正在尝试使用websocket建立一个聚会系统，使人们可以进入队列，然后与5个与他们相似的人相匹配。现在，我在这部分上遇到了麻烦：

type PartyHub struct {
    Partys             map[string]*Party
    PartialPartys      []*PartialParty
    Queue              []*Member
    AddParty           chan *Party
    RemoveParty        chan *Party
    AddPartialParty    chan *PartialParty
    RemovePartialParty chan *PartialParty
    EnterQueue         chan *Member
    LeaveQueue         chan *Member
    Mu                 sync.Mutex
}
// Run will begin monitoring the channels
// to register and unregister partys as they are
// created or destroyed
func (p *PartyHub) Run() {
    for {
        select {
        case member := <-p.EnterQueue:
            go p.SortMemberIntoParty(member)
            go p.SortMemberIntoParty(member)
            go p.SortMemberIntoParty(member)
            go p.SortMemberIntoParty(member)
            go p.SortMemberIntoParty(member)

            log.Println(p.PartialPartys)
        case party := <-p.AddPartialParty:
            p.Mu.Lock()
            defer p.Mu.Unlock()
            p.PartialPartys = append(p.PartialPartys, party)
        }
    }
}

// SortMemberIntoParty will take a new user entering the queue and find an appropriate Party
// for the member to join, taking into account RankTollerance, Rank
func (p *PartyHub) SortMemberIntoParty(member *Member) {
    p.Mu.Lock()
    defer p.Mu.Unlock()
    if len(p.PartialPartys) == 0 {
        log.Println("Here")
        newParty := &PartialParty{Accepting: true, Members: []*Member{member}}
        p.AddPartialParty <- newParty
        return
    }

    foundPartyForMember := false
    for _, party := range p.PartialPartys {
        goodFitForParty := true
        for _, partyMember := range party.Members {
            log.Println(member.Type == partyMember.Type, member.Rank >= partyMember.Rank-partyMember.RankTol, member.Rank <= partyMember.Rank+partyMember.RankTol)
            if member.Type == partyMember.Type && member.Rank >= partyMember.Rank-partyMember.RankTol && member.Rank <= partyMember.Rank+partyMember.RankTol {

                goodFitForParty = true
                continue
            } else {
                goodFitForParty = false
                break
            }
        }

        if !goodFitForParty {
            continue
        } else {
            foundPartyForMember = true
            party.Mu.Lock()
            defer party.Mu.Unlock()
            party.Members = append(party.Members, member)
            if len(party.Members) == 5 {
                party.Accepting = false
                go party.SendReadyCheck()
            }
            break
        }
    }


    if !foundPartyForMember {
        newParty := &PartialParty{Accepting: true, Members: []*Member{member}}
        p.AddPartialParty <- newParty
    }

    log.Println("Sorting Members")
}

唯一的问题是，这5个文件goroutines似乎比数据所知道的快得多。

例如：p.PartialPartys说没有聚会。

我需要的是p.PartialPartys始终对goroutine访问该PartyHub结构的该字段的每个对象保持最新状态，尽管这sync.Mutex会为我做到这一点，但事实并非如此，有人可以告诉我保留所有goroutine的最佳方法吗？与相同数据同步？
