// Send 用来在非 loop 协程发送
func (c *Connection) Send(data interface{}, opts ...ConnectionOption) error {
if !c.connected.Get() {
return ErrConnectionClosed
}
opt := ConnectionOptions{}
for _, o := range opts {
o(&opt)
}
c.loop.QueueInLoop(func() {
if c.connected.Get() {
bytesAfterPackets := c.protocol.Packet(c, data)
c.sendInLoop(bytesAfterPackets)
if opt.sendInLoopFinish != nil {
opt.sendInLoopFinish(data)
}
}
})
return nil
}
还有这个,Send这个API我理解是异步发送消息,触发的是eventfd,这个eventfd仍然是被epoll管理的,最终也是在epoll_wait中(gev里面的poll)中被触发,这不也是在eventloop协程中发送吗?但是您的注释是非loop协程发送。

// Close 关闭连接 func (c *Connection) Close() error { if !c.connected.Get() { return ErrConnectionClosed } c.loop.QueueInLoop(func() { c.handleClose(c.fd) }) return nil }关闭连接时,为什么不直接关闭连接,而是将【关闭连接】这个任务放到异步队列里面等待执行?
为了线程安全

注释不太准确,意思是这个方法可以不在 loop 中执行
