Mausberry Shutdown Script Doesn't Save Metadata

@meleu I assumed i was using 1.7. It's what ever the last one @cyperghost posted.

Is v1.7 still under development?

This "development" is more about testing than writing code. I would love to have this device to make more tests. I tried some experimentations with @lostless via IRC but it was late night... If you find me at IRC some day feel free to contact me.

If I find some time I'll write what tests I would like to do...

Ah, I thought you didn't figure out how to work around the loop yet. I will check in IRC later!

@barrymossel we didn't. For some reason the inotify was not reading the change on the gpio. So something is up. What's weird though, is when we manually told the pi there was a change to the gpio, the script worked.

@lostless @barrymossel
The version 1.56 could be considerd as 1.70 without the inotify-part. It held all code pieces to detect emulators and to finish them and make ES shutdown properly. It uses the 1.0second endless loop that was introduced in the mausberry script.

So @meleu is working on 1.70 to break the loop.
I'm also interested in 1.70 not using it as power switch rather as a generell switch. I plan to make a small build and this code would improve much.

So meleu will "release" two version.

A shutdown script with better GPIO detection (inotify)
A shutdown script with 1.0sec loop as introduced in mausberry

Why two versions? Simply the inotify package isn't preinstalled!

We can all be happy to have one so extrem gifted coder here in our forum.
Thank you meleu!

Myself got's only a long breath and is willing to learn something new.

Would using a script like this be possible with the retropie powerblock?

cyperghost

@Capeman

Seems so.... But please .... we create annother thread

barrymossel

v1.56 works for me. SCUMMVM shuts down immediately without exiting to ES. Is that correct?

lostless

@barrymossel the script is supposed to exit back to es then shut down. Check with other emulators and see if it does that. If not, something is wrong

barrymossel

Only ScummVM. Probably because than one was an exception. But I don't know whether this would be expected behavior for ScummVM or not. Guess @meleu will tell ;)

cyperghost

@barrymossel Please can you use PID detector and check PIDs displayed?
Use ps -a and check PIDs?

meleu

@barrymossel and post the exact script you're using on ghostbin.com or something.

Capeman

If there's any powerblock users, this code works without a hitch with powerblock also, just a simple file edit. How elegant and simple, you guys are awesome!

Powerblock proper ES shutdown

Sure, when I get back home. What do you want me to do exactly?

@meleu said in Mausberry Shutdown Script Doesn't Save Metadata:

Sure, will do so in some hours.

cyperghost

@barrymossel

Post code of your current switch bash to ghostbin.com and give us the link
Run emulator ScummVM
2.1 Connect with SSH
2.2 Check PIDs (Process ID) during emulator is running
2.2.1 Use PID Detector script
2.2.2 ps - a if PIDs are equal

if PID detector output one number and you type kill PIDNUMBER then the emulator should close :)

Because you said your script (version 1.56) does not work with ScummVM so let us invetigate.

I actually didn't say it "doesn't work" with ScummVM. It just looks like it doesn't exit to ES first, but it looks like it goes straight to shutdown. I am just wondering if that is expected.

But I will do the above in a sec.

2335 vs. 2336

pi@retropie:~ $ bash pidtest.sh

An emulator is currently running!
It's PID is: 2335

EmulationStation is runnuning!
ES's PID is: 1008
pi@retropie:~ $ ps -a
  PID TTY          TIME CMD

And another test: 6901 vs 6902

pi@retropie:~ $ bash pidtest.sh

An emulator is currently running!
It's PID is: 6901

EmulationStation is runnuning!
ES's PID is: 1008

 1005 tty1     00:00:00 emulationstatio
 1008 tty1     00:01:52 emulationstatio
 6815 tty1     00:00:00 sh

@barrymossel
You see PID Detector says an emulator is running with PID xxxx.

What happens if you kill that PID with kill xxxx and can you also enter output of ps -a after the kill command?

The script is v 1.56! So it's the newest version.

barrymossel

pi@retropie:~ $ kill 6901
pi@retropie:~ $ ps -a
  PID TTY          TIME CMD
  992 tty1     00:00:00 bash
  997 tty1     00:00:00 bash
  998 tty1     00:00:00 emulationstatio
 1005 tty1     00:00:00 emulationstatio
 1008 tty1     00:01:54 emulationstatio
 6902 tty1     00:01:00 scummvm
10250 pts/0    00:00:00 ps

So ScummVM keeps running. I guess, as expected.

cyperghost

@barrymossel That's interesting!
That's because ScummVM creates itself a bash call.

meleu

@cyperghost said in Mausberry Shutdown Script Doesn't Save Metadata:

That's because ScummVM creates itself a bash call.

I would change this sentence to: "That's because runcommand starts ScummVM through a bash call."

;-)

cyperghost

@meleu Ready for quick'n'dirty coding? :)

what about a kill $(expr $emupid + "1")
of course you check before if pid is active :)
