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_CTLADD 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_CTLMOD/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。
