Sorry, fixing formatting from previous post (no edit?)

// retrieve bind info
if (port_ == 0 && retries <= retryLimit_) {
struct sockaddr_storage sa;
socklen_t len = sizeof(sa);

> This patch builds upon a previously submitted patch that was not accepted
> (THRIFT-966). The purpose of this patch is to allow TServerSocket to bind to
> port zero, that is, have the server socket be assigned a port by the OS.
> This patch provides a way to query the port after the socket has been bound
> and determine the OS assigned port
