Hello All
first I apologize for my English, I'm not a native speaker.
I have a question about how golang reads the sockets in tcp.
Imagine I send , using a conn.Write(buffer), a buffer which has the
(unpredictable) size from 80 Bytes to 1516.
Now, if I do something like this (after creating "ln"):
for {
> message := make([]byte, 1516)
> var err error
> // accept connection on port
> conn, _ := ln.Accept()
> mytimeout := 1000
> mytimeout, _ = strconv.Atoi(cf.GConfig["TimeOut"])
> Gtimeout := time.Duration(mytimeout) * time.Millisecond
> conn.SetReadDeadline(time.Now().Add(Gtimeout))
>
> _, err = conn.Read(message)
> if err != nil {
> conn.Close()
> continue
> }
*messageinterpreter(message) // just do something with message*
}
what I am afraid is that , when the client is sending i.e 100 chars using
conn.Write(100chars) , the conn.Read will not understand the size, and not
stop until it has read 1516 bytes
What is the expected behavior in such a case? I cannot serialize this
content (which is binary) because I fear the impact of overhead.
thanks in advance for any comment.
