Description

It seems that is not possible to stop CFEngine with the commands of /etc/init.drudder-agent on Rudder 2.5

The only way to reproduce this bug is to have the files /var/rudder/cfengine-community/{cf-execd.pid,cf-serverd.pid} empty.

During the stop process, the files are removed:

root@rudder-snapshot:~# ls -lh /var/rudder/cfengine-community/cf-*
-rw-r--r-- 1 root root 6 Apr 24 12:08 /var/rudder/cfengine-community/cf-execd.pid
-rw------- 1 root root 6 Apr 24 12:08 /var/rudder/cfengine-community/cf-serverd.pid

root@rudder-snapshot:~# /etc/init.d/rudder-agent stop
rudder-agent[28372]: [INFO] Using /etc/default/rudder-agent for configuration
rudder-agent[28375]: [INFO] Using /var/rudder/cfengine-community for CFEngine workdir
rudder-agent[28376]: [INFO] Halting CFEngine Community cf-serverd...
rudder-agent[28380]: [OK] CFEngine Community cf-serverd stopped after 2 seconds
rudder-agent[28381]: [INFO] Halting CFEngine Community cf-execd...
rudder-agent[28385]: [OK] CFEngine Community cf-execd stopped after 2 seconds

root@rudder-snapshot:~# root@rudder-snapshot:~# ls -lh /var/rudder/cfengine-community/cf-*
-bash: root@rudder-snapshot:~#: command not found

...but it is still possible to stop:

root@rudder-snapshot:~# /etc/init.d/rudder-agent stop
rudder-agent[28395]: [INFO] Using /etc/default/rudder-agent for configuration
rudder-agent[28398]: [INFO] Using /var/rudder/cfengine-community for CFEngine workdir
rudder-agent[28399]: [INFO] Halting CFEngine Community cf-serverd...
rudder-agent[28400]: [INFO] can't read PID file, not stopping cf-serverd
rudder-agent[28401]: [INFO] Halting CFEngine Community cf-execd...
rudder-agent[28402]: [INFO] can't read PID file, not stopping cf-execd
rudder-agent[28408]: [INFO] Found no CFEngine Community cf-serverd processes running
rudder-agent[28415]: [INFO] Found no CFEngine Community cf-execd processes running

If I have an empty file, the stop process will hang for a certain amount of time:

root@rudder-snapshot:~# touch /var/rudder/cfengine-community/cf-execd.pid

root@rudder-snapshot:~# /etc/init.d/rudder-agent stop
rudder-agent[28437]: [INFO] Using /etc/default/rudder-agent for configuration
rudder-agent[28441]: [INFO] Using /var/rudder/cfengine-community for CFEngine workdir
rudder-agent[28442]: [INFO] Halting CFEngine Community cf-serverd...
rudder-agent[28443]: [INFO] can't read PID file, not stopping cf-serverd
rudder-agent[28444]: [INFO] Halting CFEngine Community cf-execd...
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]

If the file contain not an integer, it will just warn about an error and will delete the file (all will be OK again):

root@rudder-snapshot:~# echo "21.1" > /var/rudder/cfengine-community/cf-execd.pid

root@rudder-snapshot:~# /etc/init.d/rudder-agent stop
rudder-agent[28548]: [INFO] Using /etc/default/rudder-agent for configuration

rudder-agent[28554]: [INFO] Halting CFEngine Community cf-execd...

root@rudder-snapshot:~# ls -lh /var/rudder/cfengine-community/cf-execd.pid
ls: cannot access /var/rudder/cfengine-community/cf-execd.pid: No such file or directory

During start, whatever the file exists or not, all will be ok:

root@rudder-snapshot:~# touch  /var/rudder/cfengine-community/cf-execd.pid

root@rudder-snapshot:~# /etc/init.d/rudder-agent start
rudder-agent[28816]: [INFO] Using /etc/default/rudder-agent for configuration
