Hello all, I've got a program (program X) that does the following: * opens a socket (socket A) * binds socket A to an address/port (x.x.x.x/1099) * then opens another socket (socket B), * binds socket B to an address/port (x.x.x.x/1100) * calls listen on socket B * launches a second program (program Y) with proc_open * accepts a connection on socket B (presumably from program Y) * sends a packet on socket B * reads a packet from socket B * listens on socket A <========== PROBLEM * accepts a connection on socket A (from whomever is trying to connect) To be clear, the socket B stuff was just added. socket A has always existed and worked just fine. Each socket resource is stored in a distinct variable. Where things go wrong, now that I've added socket B, is when I call socket_accept() on socket A... For some reason, the socket_accept($sock) call will not block, even after I've added an explicit socket_set_block($sock) call immediately preceding the socket_accept($sock) call. I don't think there are actually any connections waiting when I call socket_accept($sock), as the socket_accept call returns false. Although, the socket_strerror(socket_last_error($sock)) returns "Success". This seems like the behavior I would expect if my socket was set to non-blocking. Here are the options, from socket_get_options, for socket A before I call accept: Resource id #17 [DEBUG] 0 Resource id #17 [ACCEPTCON] Resource id #17 [BROADCAST] 0 Resource id #17 [REUSEADDR] 0 Resource id #17 [KEEPALIVE] 0 Resource id #17 [LINGER] l_onoff = 0 Resource id #17 [LINGER] l_linger = 0 Resource id #17 [OOBINLINE] 0 Resource id #17 [SNDBUF] 16384 Resource id #17 [RCVBUF] 87380 Resource id #17 [ERROR] 0 Resource id #17 [TYPE] 1 Resource id #17 [DONTROUTE] 0 Resource id #17 [RCVLOWAT] 1 Resource id #17 [RCVTIMEO] sec = 0 Resource id #17 [RCVTIMEO] usec = 0 Resource id #17 [SNDLOWAT] 1 Resource id #17 [SNDTIMEO] sec = 0 Resource id #17 [SNDTIMEO] usec = 0 It seems to me that the actions I'm taking on socket B are somehow dirying socket A. Anyone know of any problems reported with this? I'm using PHP 4.3.11. But, I don't see anything in the changelogs that would indicate something like this has been fixed since 4.3.11. Also, when my socket_accept call fails for socket A, I try to close the socket and re-open it, but (even after calling socket_close) when I try to bind to the same address/port as I did the first time around, socket_bind fails and tells me "Address already in use"... (and I try it repeatedly, sleeping 5 seconds between attempts, and it never becomes available). Any help or pointers would be appreciated.
