Bug description: timeout is ignored in stream_select function
Description:
------------
Timeouts are ignored in stream_select. Instead, it always
returns with "1" as the number of streams affected, ignoring
any timeout seconds that are set.
This is true regardless of stream_set_blocking settings.
This may or may not be related to my reported FEOF problems:
pr #25649 (Sep 2003)
pr #32858 (Apr 2005)
Reproduce code:
---------------
$fp = fopen( '/var/log/maillog','r' );
## Tried both ways, got same results
#stream_set_blocking( $fp,TRUE );
#stream_set_blocking( $fp,FALSE );
$r = array( $fp );
while( TRUE ) {
$n = stream_select( $r,$w=NULL,$e=NULL,30 );
if( $n===FALSE ) echo "stream_select = FALSE\n";
else echo "stream_select = $n\n";
echo fgets($fp);
print( '.' );
}
Expected result:
----------------
Assuming no other program is writing to /var/log/maillog, I expect to see
a timeout condition every 30 seconds, as such:
stream_select = FALSE
Actual result:
--------------
Instead, I see iterations of:
stream_select = 1
as fast as the system can execute the loop.
