websocket's Issues

send_a_frame

connection.cpp
send_a_frame function
the function of bufferevent_write return value is 0 or -1
fb->len is the real data length

so the return value always is -1

关于websocket 握手中禁止EV_READ选项

哈喽，我想问一下，在websocket握手的时候，禁用调用libevent 的EV_READ选项，如果这个时候客户端断掉连接，应该不能及时的关闭掉连接，并且 bufferevent_write向一个关闭的fd去写，也是不会触发异常的，这样连接对应的bufferevent是不是就释放不掉了呢？
