Bug Description
Binary package hint: apache2
Description: Ubuntu 9.10 (Server)
Release: 9.10 (amd64)
apache2 2.2.12-1ubuntu2
php5-cgi 5.2.10.
screen 4.0.3-13ubuntu4
suphp-common 0.6.2-3
When using apache2 and php5 in cgi mode with suphp, calling the screen command to start a screen as daemon will produce strange things :
- when attached to the screen you hit Ctrl+C to quit the sceen, nothing happens, but detaching the screen is still possible with Ctrl+A+D
- when trying to close the screen with screen -X quit, the screen closes, but the process started in the screen is still running and must be killed forcefully
I tried replacing the apache2 binary with the 2.2.9-7ubuntu3.3 version from another server (with Ubuntu 8.10) and it worked as usual, so I think it is an apache bug. I don't know if the problem was also present in Ubuntu 9.04.
To reproduce the bug :
Run these lines with apache2 and php5-cgi :
<?php
system("screen -dmS screenName sleep 60");
?>
Then go to a terminal with the user who owns the script and run "screen -x screenName".
