TcpClient客户端tcpconnection.forceClose(),onconnect回调函数收到断联的消息后coredump

[yuzhenboy]

ubuntu 16.04 使用的是muduo c++11版

目的在没有接收到信息超过2分钟后，会调用forceClose强制断开连接，然后收到注册的连接回调函数的断联消息后，就会崩溃，初步分析只有在发命令的时候偶尔会发生这种情况，在没有发命令的时候，没有出现过，现在我的处理是：在准备关闭连接之前提早将连接标志位置false,使得不会在发送命令，过几秒后，再调用forceClose函数。

崩溃函数：
void EPollPoller::updateChannel(Channel* channel)
{
Poller::assertInLoopThread();
const int index = channel->index();
if (index == kNew || index == kDeleted)
{
// a new one, add with EPOLL_CTL_ADD
int fd = channel->fd();
if (index == kNew)
{
assert(channels_.find(fd) == channels_.end());
channels_[fd] = channel;
}
else // index == kDeleted
{
assert(channels_.find(fd) != channels_.end());
assert(channels_[fd] == channel);
}

channel->set_index(kAdded);
update(EPOLL_CTL_ADD, channel);

}
else
{
// update existing one with EPOLL_CTL_MOD/DEL
int fd = channel->fd();
(void)fd;
assert(channels_.find(fd) != channels_.end());
assert(channels_[fd] == channel);
assert(index == kAdded);
if (channel->isNoneEvent())
{
update(EPOLL_CTL_DEL, channel);
channel->set_index(kDeleted);
}
else
{
update(EPOLL_CTL_MOD, channel);
}
}
}

不一定出现，我自己测试的时候多线程一边forceClose 一边发送消息 也没出现…………

不一定出现不要紧。至少要有一个完整的能运行的程序，不然光凭文字描述我很难复现你遇到的场景。

另外，我不认识 yuto::net 这个 namespace，如果你用的不是 muduo 库本尊，请考虑把 issue 提到 yuto 库那里。
