Will you please try the workaround I suggested?
I'm not saying it isn't a bug, I'm just suggesting something that might
help get your script working in the time it takes for this bug to get
fixed.

Surely it wouldnt matter if xinetd opened the socket blocking or
non-blocking, as the script opens STDIN which needs to be blocking....
as php is talking to stdin, *not* the socket directly..

The default mode for streams is blocking mode, so you shouldn't need to
call this function at all.

Is xinetd setting it to non-blocking before the script starts?

It does sound like you have a bug there, I just thought you might like
to try a workaround until it gets fixed.

Description:
------------
Hi,

When using xinetd with a php script - then using php to read from the
"socket" with STDIN / STDOUT, as thats how xinetd translates sockets. I
find that setting blocking on the socket like the code below, I find
the while loops and uses all my cpu time - whereas the fread should
block, and wait till it gets something..

If I uncomment the sleep line - it drops down the cpu usage, but I
would rather have the blocking working.

The process function processes the data, and is irrelevant here.

PHP Was compiled with:
./configure --enable-cli --with-sockets --with-openssl --with-curl
--enable-pcntl --enable-sigchild --with-mysql --enable-sockets

Made with:
 C_INCLUDE_PATH=/usr/kerberos/include make

Version:
PHP 4.3.4-dev (cli) (built: Sep 17 2003 16:04:24)



Reproduce code:
---------------
<?php
set_time_limit (0);
ob_implicit_flush ();
stream_set_blocking(STDIN,TRUE);
$read = array(STDIN);

while (true) {
        $buf = fread(STDIN,128);
        //if ($buf == "") { sleep(1); }
        process($buf);
        unset($buf);
}
?>

Expected result:
----------------
For the fread to block and wait for input, rather than return
immediately.

Actual result:
--------------
The fread returns (even with no data), and loops.
