Ok, I give up. I can see no one wants to fix this so let other people
have the same problem. To cancel bugs after 1 week with no feedback is
absurd. Doesn't make it not a bug!
I will not report any future bugs either.

No, -F is correct. If the log file is rotated, tail will follow it.

Isn't it tail that "hangs" since you use -F instead of -f ?

Same result, no difference, no "ok" displayed

Description:
------------
Using proc_open to open a pipe to a command, and, putting stream_select
into a function, hangs upon return from that function.
Reproduce code:
---------------
<?php
function SelectStream($StreamsArray) {
$Null = array();
$timeout = NULL;
stream_select($StreamsArray, $Null, $Null, $timeout);
echo "After select\n";
return FALSE;
}
$ProcDescriptor = array(1 => array("pipe", "w"));
$Resource = proc_open("tail -F /var/log/mail.log", $ProcDescriptor,
$Pipes, NULL, NULL, array("binary_pipes" => TRUE));
if ($Resource === FALSE) die("proc_open failed\n");
$ProgResource = $Pipes[1];
/*
$ProgResource = popen("tail -F /var/log/mail.log", "r");
if ($ProgResource === FALSE) die("Could not open the PIPE\n");
*/
$Streams[] = $ProgResource;
$Resource = SelectStream($Streams);
echo "ok\n";
?>
Expected result:
----------------
I expect ok to be displayed. If you replace proc_open with popen
(uncomment the lines), the same function returns fine (ok displayed).
If
you remove the stream_select, it also returns fine.
Actual result:
--------------
The string ok is not displayed, the statement is never reached. After
select is displayed. So, it is hanging on the return statement.
