Bug ID: 54963
Summary: Concurrent issue of Spdy/NetSupportSocket
Product: Tomcat 8
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Connectors
Assignee: dev@tomcat.apache.org

Patch for NetSupportSocket
Duplicated Threads were started for doing "onBlockingSocket" in
NetSupportSocket.java
When a socket is coming, Listener creates a Runnable and executes the runnable
with Thread Pool.
In "onAccept", it invokes the method "onBlockingSocket". And the same method
will be invoked in "ctx.getExecutor().execute(ch.inputThread);" as well.
It means there are two threads work on one sinle Socket. This cause concurrent
issue.
Here is the orginal code,
@Override
public void onAccept(Object socket) {
SpdyConnectionSocket ch = new SpdyConnectionSocket(ctx, (Socket)
socket);
ctx.getExecutor().execute(ch.inputThread);
ch.onBlockingSocket();
}
Just remove the line "ctx.getExecutor().execute(ch.inputThread);" will fix this
issue.
