> Project: Hadoop Common

> if an IOException error is thrown in DomainSocket.close we go into infinite
> loop.
> Issue : If the shutdown0(fd) call throws an IOException we break out of the
> if shutdown call but will continue to loop in the while loop infinitely since
> we have no way of decrementing the counter. Please scroll down and see the
> comment marked with Bug Bug to see where the issue is.
> {code:title=DomainSocket.java}
> @Override
> public void close() throws IOException {
> // Set the closed bit on this DomainSocket
> int count = 0;
> try {
> count = refCount.setClosed();
> } catch (ClosedChannelException e) {
> // Someone else already closed the DomainSocket.
> return;
> }
> // Wait for all references to go away
> boolean didShutdown = false;
> boolean interrupted = false;
> while (count > 0) {
> if (!didShutdown) {
> try {
> // Calling shutdown on the socket will interrupt blocking system
> // calls like accept, write, and read that are going on in a
> // different thread.
> shutdown0(fd);
> } catch (IOException e) {
> LOG.error("shutdown error: ", e);
> }
> didShutdown = true;
> // *BUG BUG* <-- Here the code will never exit the loop
> // if the count is greater then 0. we need to break out
> // of the while loop in case of IOException Error
> }
> try {
> Thread.sleep(10);
> } catch (InterruptedException e) {
> interrupted = true;
> }
> count = refCount.getReferenceCount();
> }
> // At this point, nobody has a reference to the file descriptor,
> // and nobody will be able to get one in the future either.
> // We now call close(2) on the file descriptor.
> // After this point, the file descriptor number will be reused by
> // something else. Although this DomainSocket object continues to hold
> // the old file descriptor number (it's a final field), we never use it
> // again because this DomainSocket is closed.
> close0(fd);
> if (interrupted) {
> Thread.currentThread().interrupt();
> }
> }
