Bug Type: CGI related
Operating System: Linux (Fedora Core 3)
PHP Version: 5CVS-2005-05-08 (dev)
New Comment:
The issue is the same when using stream_socket_server.
stream_socket_accept works as expected, but if you select the socket it
always returns 0, even if there is a pending connection which would be
returned with stream_socket_accept.

Correction to the previous comment. The fread has to be done before
every stream_select to obtain any other value from stream_select other
than 0. stream_get_meta_data also reports pending data as 0 before the
fread and non-zero value right after the 1 byte fread.

Also, adding "fread($c,1);" after stream_socket_client and before the
while loop enables correct functionality of the stream_select function
from that pont on.

Description:
------------
Using stream_socket_client or stream_socket_server to open a connection
fails to report correct values with stream_select. Using fread to get
one byte before stream_select suddenly makes stream_select work as
expected.
Without it stream_select returns 0 changed streams even though there is
data waiting. Service used as an endpoint is persistent and doesn't
close the connection after it's output. PHP is CLI-version.
Reproduce code:
---------------
$c = stream_socket_client("tcp://127.0.0.1:80");
while (1)
{
$streams = array($c);
if (stream_select($streams, $write=NULL, $except=NULL, 0, 5000)) {
print "Data received\n";
}
}
// IP:Port can be anything which outputs something after connection.
Expected result:
----------------
Text "Data received" after connection and output from the service. The
service can be anything which just outputs something right after
connect.
Actual result:
--------------
Nothing. stream_select returns 0 even though there is data waiting.
