Reported By: vesely at tana dot it
Status: Wont fix
Bug Type: Unknown/Other Function
Operating System: Unix
PHP Version: 4.4.0
New Comment:
Perhaps you may check the following code, please?
When migrating to 5.x we will have to review c'tors
anyway, so it seems fine to me. Strange as it looks,
I wouldn't bet about unwanted side effects. If you
feel like recommending it, I'll post a pointer to this
bug in the relevant manual page.
Workaround code:
----------------
<?php
class my_class
{
var $proc, $pipes;
function my_class() {
// open in c'tor hangs on fatal error
// $this->open();
}
function open() {
$this->proc = proc_open("cat -",
array(
0 => array("pipe", "r"),
1 => array("file", "/dev/null", "w"),
2 => array("file", "/dev/null", "w")),
$this->pipes);
$GLOBALS[uniqid("my_class_proc_open_")] = $this->proc;
}
}
$p = new my_class();
$p->open();
printf("%s proc hangs on fatal PHP error?\n",
is_resource($p->proc) ? "Open" : "Not open");
non_existing_function("does not hang: just aborts");
// not reached...
?>

It's fixed in 5.x, but I don't think that the fix will get into 4.4.0
ever, as it was just a small part of exec()/proc_open() overall
rewrite.
So I'd say you have to live with that (or use 5.x instead, this is a
perfect reason to start using it).

Description:
------------
If the proc_open was inside a class object,
then on a fatal error the child process
is not killed. (Both CLI and Apache.)
That behaviour makes it difficult to develop
scripts based on classes using proc_open.
If the $proc is not inside a class object,
I obtained a similar freezing doing $proc = 0
before the fatal error.
Reproduce code:
---------------
<?php
class my_class
{
var $proc, $pipes;
function my_class() {
$this->proc = proc_open("cat -",
array(
0 => array("pipe", "r"),
1 => array("file", "/dev/null", "w"),
2 => array("file", "/dev/null", "w")),
$this->pipes);
}
}
$p = new my_class();
printf("%s proc hangs on fatal PHP error?\n",
is_resource($p->proc) ? "Open" : "Not open");
non_existing_function("hangs if open");
// not reached...
?>
