java.net.SocketTimeoutException: Read timed out exception while reading from dumper

[Veenavani Revanuru]

Hi,

I am getting the foll. exception when I try to get the dump on a port connecting to the server where the jacoco agent is running

My goal is to capture the test coverage after evety test is run, henc I  am calling the jacoco dumper 

I have the jacoco  agent  running with below params:

set the foll in weblogic appserver

JAVA_OPTIONS="${JAVA_OPTIONS} -

javaagent:/podscratch/jacoco/jacocoagent.jar=output=tcpserver,address=xxxxx,port

=6015,append=false,dumponexit=false,classdumpdir=/podscratch/classdumpdir,destfile=/podscratch/co

verage/coverage.exec"

Exception:

--------------------------------------

I get the below exception while it reads from the dumper:

Exception in thread "main" java.net.SocketTimeoutException: Read timed out

        at java.net.SocketInputStream.socketRead0(Native Method)

        at java.net.SocketInputStream.socketRead(Unknown Source)

        at org.jacoco.core.data.ExecutionDataReader.read(ExecutionDataReader.jav

a:82)

        at JacocoDumper.main(JacocoDumper.java:58)

My dumper code is something like this:

ublic class JacocoDumper{

private static final String DESTFILE = "jacoco-client.exec";

private static final String ADDRESS = "slc09rjj.us.oracle.com";

private static final int PORT = 6015;

public static void main(String args[]) throws Exception{

//command to run the test

String[] out1 = runCommand("java -jar REEATSGenericCLI.jar -action=execute -test_set_path="Test1" );

        String jobId = null;

System.out.println((jobId= out1[0].split("job id=\"")[1].split("\"")[0]));

String[] out2 = null;

for(;;){

Thread.sleep(1000);

out2 = runCommand("java -jar ALM\\REEATSGenericCLI.jar -action=status  -job_id=\""+jobId+"\"");

if(!out2[1].contains("Given job not found."))

break;

}

}

System.out.println(out2[0]);

final FileOutputStream localFile = new FileOutputStream(DESTFILE);

final ExecutionDataWriter localWriter = new ExecutionDataWriter(

localFile);

// Open a socket to the coverage agent:

final Socket socket = new Socket(InetAddress.getByName(ADDRESS), PORT);

final RemoteControlWriter writer = new RemoteControlWriter(

socket.getOutputStream());

final RemoteControlReader reader = new RemoteControlReader(

socket.getInputStream());

reader.setSessionInfoVisitor(localWriter);

reader.setExecutionDataVisitor(localWriter);

// Send a dump command and read the response:

System.out.println("before dump ");

writer.visitDumpCommand(true, true);

System.out.println("after dump  read");

if (!reader.read()) {

throw new IOException("Socket closed unexpectedly.");

}

socket.close();

localFile.close();

}

Any idea on waht the issue?

thanks

Even the jacococli throws the similar error:

>>java -jar jacococli.jar dump --destfile jacoco.exec --address xxxx   --port 6015

private static final String ADDRESS = "xxxx"

Hi,

hard to tell what the issue are. It looks like the target prozess is not properly running or has been killed during the dump (connection reset).

Note that output=tcpserver only works for long running processes. The process with the attached JaCoCo agent needs to be up and running for the entire time while executing the dump command.

Another possible reason might be firewall or routing issues.

Regards,
