Bug ID: 2114
Summary: pipe transport timeout has no effect when parent
process exits while child continues to run
Product: Exim
Version: 4.88
Hardware: All
OS: All
Status: NEW
Severity: bug
Priority: medium
Component: Transports
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
I have the following router:
virtual_faxtest:
driver = accept
domains = faxtest.example.com
transport = faxtest_delivery
cannot_route_message = Test router error
and this transport:
faxtest_delivery:
driver = pipe
command = /home/pbackes/send_faxtest.php
timeout = 10s
return_fail_output
#log_fail_output
#log_defer_output
log_output
temp_errors = 73 : 75 : 255
message_prefix =
message_suffix =
with send_faxtest.php being:
#!/usr/local/bin/php
<?php
$mail_conv = proc_open("/home/pbackes/idle",array(0 => array('pipe','r'),1 =>
array('pipe','w')),$pipes,'/tmp');
exit(1);
?>
and idle being compiled idle.c:
int main(void)
{
for (;;)
continue;
}
Then, when I send email to [email protected], idle keeps running despite
the timeout of 10 seconds, and the exim delivery process (/usr/local/sbin/exim
-Mc $ID) keeps running indefinitely. I have to kill -9 the idle process
manually. The timeout should be honored.
Using "for (;;) continue;" instead of "exit(1);" in send_faxtest.php and
everything (obviously) works as it should.
