Description Karel Volný 2010-06-18 12:15:50 EDT

the initscript does not implement some mandatory actions, it does not implement some actions correctly, and does not report correct status

please see https://fedoraproject.org/wiki/Packaging/SysVInitScript

1) the initscript does not implement 'condrestart'

2) the initscript does not implement 'try-restart'

3) the initscript does not implement 'force-reload'

4) running "service edac status" after "service edac stop" returns 0 instead of 3

5) running "service edac reload" on a stopped service returns 0 instead of 7 and restarts the service

6) for invalid arguments, instead of returning error message and status code 2, the initscript prints usage message and returns 0 - but usage message should be printed only if run without arguments or with "usage" argument

7) running the initscript as non-root user does not return error and status code 4 (except for usage and status, it should be allowed), but it tries to perform the actions which leads to permission denial errors

Comment 2 RHEL Product and Program Management 2010-06-18 12:43:29 EDT

Such return codes wouldn't make any sense on this case. This script should not
be different than the one provided for bluetooth, where only a start method is
defined:

start()
{
	echo -n $"Enabling Bluetooth devices:"
	udevadm trigger --subsystem-match=bluetooth
	echo ""
	return 0
}

stop()
{
	# FIXME If somebody figures out how to disable the K* script
	echo -n "Stopping Bluetooth services:"
	echo ""
	return 0
}

It is just the same case: we just need to run edac-ctl during start method,
in order to load some parameters at the corresponding kernel driver. This script doesn't start any deamon that needs to be stopped. I think I'll rewrite
the init script to look more like the above, adding some fake methods for all
those restart methods that will just call edac-ctl whatever argument provided,
except for stop and usage.

Comment 4 Mauro Carvalho Chehab 2010-06-22 20:18:37 EDT

Created attachment 426119 [details]
New EDAC SysV script

New script that fulfills all requirements stated at:
https://fedoraproject.org/wiki/Packaging/SysVInitScript#Initscripts_on_the_filesystem

Since this script just sends some data to EDAC kernel driver, there's no stop action, nor there is a "daemon status". So, all actions that asks for reload will just do the same action as "start": send the new memory labels table to the Kernel driver. "stop" and "status" will just return 0, as there's no way (nor make sense) to stop a non-daemon process.

New SysV script added at: edac-utils-0.9-11.2.el6.src.rpm
