Hi, all, One problem was found at most releases of APR.
Problem description: When using APR-1.3.5 on PPC, Apache HTTP server couldn't response HEAD message. Root Cause: After investigation, I found that there is a bug in APR when accepting a new conneciton. In function apr_socket_accept of file apr-1.3.5/network_io/sockets.c, if the new socket finds its father socket is non-blocking, it calls *apr_set_option* to change its own non-blocking mode. However, the function *apr_set_option* only changes the value in struct apr_socket_t, and the real non-blocking mode of the socket has not been modified. So I think we'd better call function *apr_socket_opt_set* to set the real non-blocking mode of the new socket. Please see attached for the patched file. Thanks, Tony
