Description:
------------
After a process (via proc_open()) has exited, proc_get_status() returns
the actual exit code (within array['exitcode']) of that process.
If proc_get_status() gets called a second time, the previous exit code
will be lost (-1), because the internal waitpid() function won't return
the pid a second time.
So, either this is a bug and proc_get_status() has to keep track of the
exitcode value (as it does for 'command', 'pid' and 'running') or this
behaviour should be mentioned in the documentation.
Reproduce code:
---------------
#!/usr/bin/env php
<?php
$descriptors = array(
0 => array('pipe', 'r'),
1 => array('pipe', 'w'),
2 => array('pipe', 'w'));
$pipes = array();
$ressource = proc_open('/bin/true', $descriptors, $pipes);
echo stream_get_contents($pipes[1]);
// first call exitcode == 0
var_dump(proc_get_status($ressource));
// second call exitcode == -1
var_dump(proc_get_status($ressource));
fclose($pipes[1]);
proc_close($ressource);
?>
Expected result:
----------------
array(8) {
["command"]=>
string(9) "/bin/true"
["pid"]=>
int(31590)
["running"]=>
bool(false)
["signaled"]=>
bool(false)
["stopped"]=>
bool(false)
["exitcode"]=>
int(0)
["termsig"]=>
int(0)
["stopsig"]=>
int(0)
}
array(8) {
["command"]=>
string(9) "/bin/true"
["pid"]=>
int(31590)
["running"]=>
bool(false)
["signaled"]=>
bool(false)
["stopped"]=>
bool(false)
["exitcode"]=>
int(0)
["termsig"]=>
int(0)
["stopsig"]=>
int(0)
}
Actual result:
--------------
array(8) {
["command"]=>
string(9) "/bin/true"
["pid"]=>
int(31590)
["running"]=>
bool(false)
["signaled"]=>
bool(false)
["stopped"]=>
bool(false)
["exitcode"]=>
int(0)
["termsig"]=>
int(0)
["stopsig"]=>
int(0)
}
array(8) {
["command"]=>
string(9) "/bin/true"
["pid"]=>
int(31590)
["running"]=>
bool(false)
["signaled"]=>
bool(false)
["stopped"]=>
bool(false)
["exitcode"]=>
int(-1)
["termsig"]=>
int(0)
["stopsig"]=>
int(0)
}
