in addition to the compile failure I found that mysqld will not return from the following mysqld.cc line even when a connection is made.
I verified that readFDs does contain the FD_ISSET(unixfd,readFDs).
retval= select((int) 0,&readFDs,0,0,0);It seems that the first arguement is the number of fd. The 4th arguement is exceptions.
changing the code to:
retval= select(socket_count,&readFDs, 0, &readFDs, 0);Did not change its locking behaviour. Only tested with unix sockets.
