socket.setSoTimeout(100) causes error "protocol not available"

[GoogleCodeExporter]

What steps will reproduce the problem?
code:
    File socketFile = new File("/tmp/cgi.socket");
    AFUNIXSocket sock = AFUNIXSocket.newInstance();
    sock.connect(new AFUNIXSocketAddress(socketFile));
    sock.setSoTimeout(12000);
    sock.close();

output:
org.newsclub.net.unix.AFUNIXSocketException: Protocol not available
    at org.newsclub.net.unix.NativeUnixSocket.setSocketOptionInt(Native Method)
    at org.newsclub.net.unix.AFUNIXSocketImpl.setOption(AFUNIXSocketImpl.java:319)
    at java.net.Socket.setSoTimeout(Socket.java:1003)

is there any solution? thanks~~

Hi Kaifuxu,

thanks for hinting me at this. I could not reproduce the "Protocol not 
available" error, but on OS X I was able to get an "invalid argument" error in 
some cases.

This happens if the socket is closed before Socket#setSoTimeout gets called, 
for example when the server decides to block the request.

In SVN trunk, I have added a new JUnit testcase (SoTimeoutTest) to trigger the 
problem.

Please let me know if that testcase fails for you.

Best,
Christian

Thanks for the feedback, kaifuxu.

Does this mean that, using the SVN trunk, you cannot reproduce the "protocol 
not available" error? Or will this error only occur if the socket was closed 
prematurely?

Best,
Christian

Hi, Christian

I did as below on Ubuntu Desktop 10.04 and SuSE Enterprise Server 10.2 ~

# wget http://junixsocket.googlecode.com/files/junixsocket-1.2-bin.tar.bz2 
# tar -xf junixsocket-1.2-bin.tar.bz2
# mkdir -p /opt/newclub/lib-native
# chmod +x junixsocket-1.2/lib-native/libjunixsocket-linux-1.5-i386.so
# cp junixsocket-1.2/lib-native/libjunixsocket-linux-1.5-i386.so 
/opt/newclub/lib-native

and run my program,  then the error happened. 

so I checked out the source from svn :

# rm -fr /opt/newclub
# svn co http://junixsocket.googlecode.com/svn/trunk/junixsocket .
# ant -Djdk.home=/usr/lib/jvm/java-6-sun -Dgcc=/usr/bin/gcc gcc-linux.32
# mkdir /root/lib-native
# cp lib-native/libjunixsocket-linux-1.5-i386.so /root/lib-native/

and added the following line into my java source:
System.setProperty("org.newsclub.net.unix.library.path","/root/lib-native"); 

then no error occured

My Java Souce Code:

import java.io.File;
import org.newsclub.net.unix.AFUNIXSocket;
import org.newsclub.net.unix.AFUNIXSocketAddress;

public class Test {
    public static void main(String[] args) throws Exception {
        System.setProperty("org.newsclub.net.unix.library.path","/root/lib-native"); 
        File socketFile = new File("/tmp/fcgi.socket");
        AFUNIXSocket sock = AFUNIXSocket.newInstance();
        sock.connect(new AFUNIXSocketAddress(socketFile));
        sock.setSoTimeout(12000);
        sock.close();
    }
}

Best,
kaifuxu
