Plugin / Utility request: shutdown SageTV and execute a batch file

[korben_dallas]

Ok developers,

I'll be one of you guys' bestest friends ever if you would make a small plugin / addon / utility that will gracefully shutdown SageTV and then execute a DOS batch file or other executeable.

1) On a schedule, this doesn't need to be too advanced
2) Checks to make sure SageTV isn't recording before shutdown
3) Checks to see how much time before next scheduled recording, with a minimum threshold in minutes before shutdown
4) If failure to shutdown due to 2 or 3, then try again in x number of minutes with y number of retries
5) Writes datetime to a simple logfile with shutdown success, failure, retry, last retry

Just out of curiosity (as it may help someone looking to do this for you anyways), but what functionality are you trying to get with this? It is possible it is something you could already do with existing tools. (Sage Job Queue comes to mind).

[CollinR]

Yup you can make this happen with SJQ.


Damn I need to reinstall it/upgrade. It's been too long.

I need to do some once-a-week or perhaps once-a-night things to my SageTV server, but I obviously don't want the server shutting down services, processing, and rebooting while SageTV is in the middle of recording.

My understanding of SJQ is that SageTV is still running though? I need SageTV completely shut down. And, I don't want to miss a recording if, for example, my nightly server job runs at 3:30am and unbeknownce to me SageTV had something scheduled for 3:35am.

So it checks if SageTV is recording, or soon will be, and if not safely exits SageTV and runs the batch file / exe.

So in SJQ you create a job looking for all the parameters you have described. If it meets those requirements it executes a batch job that will shut down Sage, perform the maintenance you want and the last task in the batch file will restart the server or Sage itself. It should work just fine for you.

This is my ruleset and batch file.

I use windows scheduler to create a file c:\controls\oktoreboot.txt every sunday at 4:00 am.

I have SJQ run this rule set anytime c:\controls\oktoreboot.txt exists.

//Ok To Reboot
if [FileExists == "c:\\controls\\oktoreboot.txt" && IsSomethingRecording == "false" && TranscodeQueueSize < "1" && TimeUntilNextRecording > "15M" && $.GetMediaTitle{} == "Not Recording" && TimeOfDay > "05:00" && TimeOfDay < "20:00"]{
    :PRIORITY 110
      OKTOREBOOT
}

This is my batch file it reboots the clients , Sage server and cleans up temp files.

del c:\controls\oktoreboot.txt
tskill wscript /a
cd c:\SageBatch
c:
process -q SageTV.exe
net stop SageTV

del "C:\Documents and Settings\All Users\Application Data\TEMP" /q

start shutdown -m \\sageclient -r -f -t 60
start shutdown -m \\nyplayer -r -f
start shutdown -r -f -t 2
exit 1

Also anytime I want to reboot sage I simply create c:\controls\oktoreboot.txt and sage will reboot at the next convenient time.

Is there a graceful way to exit SageTV programatically?

There's the exe message event {Power Off 44}, but as I recall that only minimizes SageTV to the taskbar?

I know that externally I can kill the SageTV.exe process, but that's not really graceful.. might introduce some problems in the SageTV files.

[nyplayer]

I use a free program process.exe.

cd c:\SageBatch
c:
process -q SageTV.exe
net stop SageTV

[GKusnick]

Sage ships with a command-line utility called SendMessage.exe that can be used to send a WM_CLOSE or WM_QUIT message to the running UI.

For the service, use net stop as nyplayer indicates.

I am trying to get this shutdown script to work as well...totally new to SJQ...and am SOOO close. But I'm having a problem with the restart.

When the SJQ client batch file executes the restart, it does not complete. The restart begins, but then eventually I end up with a black screen and an arrow and the restart does not complete. I have to hit the power switch to reboot.

When I manually run the batch file from the command prompt, it works great...and completes as normal.

The only difference I an see is that when I run from the command prompt, the restart is initiated by Q6600\sage (my user name). When it is initiated from SJQ, the restart windows says the restart was initiated by NT AUTHORITY\SYSTEM.

Could that be the problem? Any suggestions how I can fix it?

I'm trying to setup SJQ to restart sagetv during the night.
I use windows scheduler to create a file c:\controls\oktorestartsage.txt every night at 2:30 am.

//Ok To Reboot
if [FileExists == "c:\\controls\\oktoreboot.txt" && IsSomethingRecording == "false" && TranscodeQueueSize < "1" && TimeUntilNextRecording > "10M" && $.GetMediaTitle{} == "Not Recording" && TimeOfDay > "02:35" && TimeOfDay < "05:00"]{
    :PRIORITY 110
      OKTOREBOOT
}

but it never runs even though I think that all the conditions are met, not sure about $.GetMediaTitle{} == "Not Recording". Is there an alternative to using $.GetMediaTitle{} == "Not Recording", does this work with snapshot version SJQ v3.0.2.792?

Any idea's why it's not working?

[nyplayer]

I used Videoredo to cut a recording(a few meg) and then I put it in the import folder then I used the webserver to name it Not Recording. You can use any title that you have just archive it and keep it around... I just got creative :-) for example && $.GetMediaTitle{} == "Double Jeopardy"

That makes sense, will give it a try. Are there any other gotcha's that will cause the batch file to not complete?

[zzmystique]

Have the restart sage and reboot SJQ rules working now , it is working well.

Took me a little while to realise that the SJQ Task Client could not be stopped during the restart or reboot process otherwise the scripts would not complete.

Cheers
