PHP Bug Type: Reproducible crash
Bug description: popen crashes webservers
Description:
------------
When run from a webserver, the following two scripts cause the webserver
to crash. In contrast, no such problem occurs when these scripts are run
from the command line.
Reproduce code:
---------------
ptest.php:
<?
$p1 = popen("c:\\php\\php -q hello.php","r");
$p2 = popen("c:\\php\\php -q hello.php","r");
while (!feof($p1))
print fgets($p1);
while (!feof($p2))
print fgets($p2);
pclose($p1);
pclose($p2);
?>
and
hello.php:
<?
print "hello,\nworld!\n";
?>
Expected result:
----------------
I expect the following to be displayed:
hello,
world!
hello,
world!
Actual result:
--------------
When run from the command line, the expected result is the actual result.
However, when run from a webserver (I tried Apache 2.0.52 and Abyss Web
Server 1.2.3.0) they create a bunch of php and cmd processes (more than it
should) and none of them are terminated.
In the case of Apache, processes are no longer created after the first 10
or so are. Afterwards, trying to view php scripts, with Apache, causes an
Internal Server Error.
In the case of Abyss, processes are no longer created when the system has
run out of ram.
