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
