Description:
------------
Very seldom the script works but in most cases it crashes.
Segmentation fault were also seen.
ini_set("memory_limit", "4g"); - does also not help
1st run = OK
All further runs crashes.
Test script:
---------------
<?php
$descriptorspec = array(0 => array("pipe", "r"), // stdin is a pipe that
the child will read from
1 => array("pipe", "w"), // stdout is a pipe that the
child will write to
2 => array("pipe", "w") // stderr is a pipe that the
child will write to
);
$process=proc_open("echo testtext",$descriptorspec,$pipes);
if(is_resource($process))
{
stream_set_blocking($pipes[0],false);
stream_set_blocking($pipes[1],false);
stream_set_blocking($pipes[2],false);
stream_set_write_buffer($pipes[0],0);
stream_set_read_buffer($pipes[1],0);
stream_set_read_buffer($pipes[2],0);
$stdin_stream="";
$stderr_stream="";
echo "External command executed\n";
do
{
$process_state=proc_get_status($process);
$tmp_stdin=stream_get_contents($pipes[1]);
if($tmp_stdin)
{
$stdin_stream=$stdin_stream.$tmp_stdin;
}
$tmp_stderr=stream_get_contents($pipes[2]);
if($tmp_stderr)
{
$stderr_stream=$stderr_stream.$tmp_stderr;
}
sleep(1);
}while($process_state['running']);
echo "External command exit: ".$process_state['exitcode']."\n";
//read outstanding data
$tmp_stdin=stream_get_contents($pipes[1]);
if($tmp_stdin)
{
$stdin_stream=$stdin_stream.$tmp_stdin;
}
$tmp_stderr=stream_get_contents($pipes[2]);
if($tmp_stderr)
{
$stderr_stream=$stderr_stream.$tmp_stderr;
}
fclose ($pipes[0]);
fclose ($pipes[1]);
fclose ($pipes[2]);
proc_close($process);
echo "STDOUT: ".$stdin_stream."\n";
echo "STDERR: ".$stderr_stream."\n";
}
else
{
echo "Can't start external command\n";
}
?>
Expected result:
----------------
External command executed
External command exit: 0
STDOUT: testtext
STDERR:
Actual result:
--------------
External command executed
