ID: 53592 Updated by: [email protected] Reported by: jerry dot wilborn at paetec dot com Summary: stream_socket_enable_crypto() uses NONBLOCK -Status: Open +Status: Assigned Type: Bug Package: Sockets related Operating System: CentOS 4.4 PHP Version: 5.3.4 -Assigned To: +Assigned To: cataphract Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2010-12-22 14:59:25] jerry dot wilborn at paetec dot com Fix summary. ------------------------------------------------------------------------ [2010-12-22 04:06:38] jerry dot wilborn at paetec dot com Description: ------------ stream_socket_enable_crypto() changes the stream to NONBLOCK before it attempts the encryption. I'm assuming this is so the timeout can be tracked, but for connections where the handshake doesn't work the process simply chews up CPU while the read() repeatedly EAGAIN fails and gettimeofday() is called. Test script: --------------- $stream = stream_socket_client("tcp://72.14.204.147:80", $errno, $errstr, 5); stream_socket_enable_crypto($stream, TRUE, STREAM_CRYPTO_METHOD_SSLv23_CLIENT); Expected result: ---------------- For the socket to stay in blocked mode. Actual result: -------------- socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3 fcntl64(3, F_GETFL) = 0x2 (flags O_RDWR) fcntl64(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0 connect(3, {sa_family=AF_INET, sin_port=htons(80), sin_addr=inet_addr("72.14.204.147")}, 16) = -1 EINPROGRESS (Operation now in progress) poll([{fd=3, events=POLLIN|POLLOUT|POLLERR|POLLHUP, revents=POLLOUT}], 1, 1000) = 1 getsockopt(3, SOL_SOCKET, SO_ERROR, [0], [4]) = 0 fcntl64(3, F_SETFL, O_RDWR) = 0 select(4, [3], [3], [], {5, 0}) = 1 (out [3], left {5, 0}) fcntl64(3, F_GETFL) = 0x2 (flags O_RDWR) fcntl64(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53592&edit=1
