The new idle.py is now a part of the LinHES 8.3 installation and upgrade.

(NO more any change in idle.py !!)

After update the LinHES-system (8.3-15 -> 8.3-19) the new version is online.
solution is in posting #4


THIS IS FOR INFORMATION ONLY

Hi,
I use my Mythbackend server as a Samba server to share my music and picture files for connected windows client PCs. On my windows machine I have an wake-on-lan batch file (WolCmd.exe) that can remotely start the Mythbackend server.
Mythwelcome and the LinHES script “/usr/LH/bin/idle.py” without some modifications have no check for active windows client connection.
I have basic experience in Linux shell scripting, but not in python programming language. But I found a solution to check for active samba connections.

Requirement are LinHES-system 8.2-5 mythtv 0.27.4-3 and
/usr/LH/bin/idle.py from Nov 20 17:27, 12947 bytes (md5sum 69ecfe682f1b61c2c4c95d890b9f523c)

You can do the following steps:
1) Make a copy of the file /usr/LH/bin/idle.py
2) Cut and Replace the function “userlogins_check”
3) Save the change in a NEW file /usr/LH/bin/idle-samba.py
4) Test the script with an active samba share
5) Make a backup copy of the file /usr/LH/bin/mythwelcome-config.py
6) Modify and execute the file /usr/LH/bin/mythwelcome-config.py
7) Check in mythtv-setup the new setting of wake up

This are the details:
1) Make a copy of the file /usr/LH/bin/idle.py
Code:
cp -a -v /usr/LH/bin/idle.py /usr/LH/bin/idle-samba.py
‘/usr/LH/bin/idle.py’ -> ‘/usr/LH/bin/idle-samba.py’

2) Cut and Replace the function “userlogins_check” in the NEW file /usr/LH/bin/idle-samba.py
Cut this lines 185-202
Code:
def userlogins_check(cmdargs):
    if (cmdargs.logins):
        u=False
        msg(cmdargs,"    Checking for users logged in...")
        users=subprocess.check_output("who")
        names=([x.split() for x in users.splitlines()])
        for i in names:
            if (i[0] == "mythtv" and i[4] == "(:0)"):
                msg(cmdargs,"        Ignoring %s %s" %(i[0],i[4]))
            else:
                msg(cmdargs,"        User logged in: %s %s" %(i[0],i[4]))
                u=True
        if u:
            return False
        else:
            return True
    else:
        return True

Replace and insert this code (Please check that the end of line is LF only (not CR LF) )
Code:
def userlogins_check(cmdargs):
    if (cmdargs.logins):
        u=False
        msg(cmdargs,"    Checking for users logged in...")
        users=subprocess.check_output("who")
        names=([x.split() for x in users.splitlines()])
        for i in names:
            if (i[0] == "mythtv" and i[4] == "(:0)"):
                msg(cmdargs,"        Ignoring %s %s" %(i[0],i[4]))
            else:
                msg(cmdargs,"        User logged in: %s %s" %(i[0],i[4]))
                u=True
        msg(cmdargs,"    Checking for active samba users....")
        samba_status = subprocess.Popen(['sudo','smbstatus'], stdout=subprocess.PIPE)
        samba_conn = "Locked files:\n" in samba_status.stdout
        if ( samba_conn ):
            msg(cmdargs,"        System is busy -active samba users-")
        else:
            msg(cmdargs,"        System is idle -no active samba users-")
        if ( u or samba_conn ):
            msg(cmdargs,"        System is busy -active linux user (ssh) or samba users-")
            return False
        else:
            msg(cmdargs,"        System is idle -no active linux user (ssh) or samba users-")
            return True
    else:
        return True

3) Save the change in the NEW file /usr/LH/bin/idle-samba.py, file listing show:
/usr/LH/bin/idle-samba.py 13547 bytes (md5sum eeb7778b2b0890497ee8c39e655cf57d)

4) Test the script with an active samba share
Open a samba share on your windows machine and open a termial session (ALT X) as a user mythtv
Code:
$ /usr/LH/bin/idle-samba.py -d -l -r -g
Checking system idle...
 Checking for users logged in...
 Checking for active samba users....
 System is busy -active samba users-
 System is busy -active linux user (ssh) or samba users-
System is busy.

If you see any python error messages stop here at step 4 and fix this!

5) Make a backup copy of the file /usr/LH/bin/mythwelcome-config.py
Code:
cp -a -v /usr/LH/bin/mythwelcome-config.py /usr/LH/bin/mythwelcome-config.py.linhes8.2
‘/usr/LH/bin/mythwelcome-config.py’ -> ‘/usr/LH/bin/mythwelcome-config.py.linhes8.2’

6) Modify and execute the file /usr/LH/bin/mythwelcome-config.py
in line 26 put a hashtag "#" and copy and modify this line in 27
Code:
#mythdb.settings.NULL.preSDWUCheckCommand = u'/usr/LH/bin/idle.py -s -d -l -r'
mythdb.settings.NULL.preSDWUCheckCommand = u'/usr/LH/bin/idle-samba.py -s -d -l -r -g'

Execute this file /usr/LH/bin/mythwelcome-config.py to update the Mythtv DB

7) Check in mythtv-setup the new setting of wake up (/usr/LH/bin/idle-samba.py -s -d -l -r -g)

End of modification
Regard Lutz

Optional:
1) If you like to have more information from the idle-samba.py script you can activate the file logging in line 5 and put your own logging.log(logging.INFO) code.
Code:
import logging
logging.basicConfig(
    filename="/var/log/mythtv/idle-samba.log",
    filemode = "a",
    level = logging.DEBUG,
    format = "%(asctime)s %(levelname)s: %(message)s",
    datefmt = "%d.%m.%Y %H:%M:%S")
logging.log(logging.INFO, "--------------------------------------------------------------")
logging.log(logging.INFO, "Starting idle.py")

You can generate a log file in /var/log/mythtv/ like
Code:
28.01.2015 18:35:03 INFO: --------------------------------------------------------------
28.01.2015 18:35:03 INFO: Starting idle.py
28.01.2015 18:35:03 INFO: User logged in: root
28.01.2015 18:35:03 INFO: System is busy -active samba users-
28.01.2015 18:35:03 INFO: System is busy -active linux user (ssh) or samba users-
28.01.2015 18:35:03 INFO: All checks status:System is busy


2) If you have problems with the message "mythshutdown is locked" you can execute
Code:
mythshutdown -u
mythshutdown -c
OK to shutdown

Hi
2015-10-06

This script works with the 8.3 version - the idle.py script have no changes in md5sum.

This are my LinHES versions
Code:
cat /etc/LinHES-release
LinHES R8.3 (Lorne Malvo)

uname -a
Linux sbx1 3.18.14-1-ARCH #1 SMP PREEMPT Wed May 27 17:12:27 UTC 2015 x86_64 GNU/Linux

cat /var/log/pacman.log |grep -i linhes
[2015-01-19 18:04] [PACMAN] upgraded LinHES-system (8.2-3 -> 8.2-5)

[2015-10-05 15:07] [PACMAN] upgraded LinHES-system (8.3-11 -> 8.3-14)


After the last update I change only the /usr/LH/bin/mythwelcome-config.py again and start mythwelcome-config.py script
Code:
#mythdb.settings.NULL.preSDWUCheckCommand = u'/usr/LH/bin/idle.py -s -d -l -r'
mythdb.settings.NULL.preSDWUCheckCommand = u'/usr/LH/bin/idle-samba.py -s -d -l -r -g'

Good idea.

I just added a -f (or --sambafiles) option to idle.py that checks for Samba files in use and includes it in system busy.

Thanks for updating the idle.py, that is now a part of the LinHES 8.3 installation and upgrade.

(NO more any change in idle.py !!)

After update the LinHES-system (8.3-15 -> 8.3-19) the new version is online.
Code:
usage: idle.py [-h] [-d] [-g] [-f] [-l] [-r] [-s] [-t TIME] [-u]

optional arguments:
  -h, --help            show this help message and exit
  -d, --daily           Include daily wake & about to start wake in system
                        busy. (default: daily wake & about to start wake is
                        system idle)
  -g, --logins          Include user logins in system busy. Ignores mythtv
                        (:0) in system busy.
  -f, --sambafiles      Include Samba files in use in system busy.
  -l, --lock            Include mythshutdown lock in system busy. (default:
                        mythshutdown lock is system idle)
  -r, --runningfe       Include running mythfrontends in system busy.
                        (default: running mythfrontends are system idle)
  -s, --silent          Run without printing output. Recommended for use in
                        cron jobs or scripts.
  -t TIME, --time TIME  Minutes of idle time needed to return idle for
                        upcoming recordings and daily wake.
  -u, --usage           Print usage instructions.



If you check for user logins and Samba files in use, use this settings of the /usr/LH/bin/idle.py
Code:
-s -d -l -r -g -f


Change the mythwelcome-config.py

Code:
/usr/LH/bin/mythwelcome-config.py
#mythdb.settings.NULL.preSDWUCheckCommand = u'/usr/LH/bin/idle.py -s -d -l -r'
mythdb.settings.NULL.preSDWUCheckCommand = u'/usr/LH/bin/idle.py -s -d -l -r -g -f'
