Mausberry Shutdown Script Doesn't Save Metadata

meleu

@cyperghost I think pgrep scummvm (without -f) would be more effective thant that.

@barrymossel I knew I made promise do not interact with this code by maybe you can try this one 1.57b - it's just a dirty workaround!

Feel free to test!

I just started a massive scrape, so I won't turn the RPi off now. Depending on when the scrape ends I will try it later or tomorrow evening.

OUTDATED !!

Yes... but I'm finished with that code. But I think using ps as entry to extract PPID should work. So this is a sniplet coded yesterday with annother intention....
Thank you :)

What does happen if you use killall command instead of kill -9 or use killall in general?

@barrymossel

as meleu alread said pgrep would be the smarter approach!
I just want to create failsafe methods but they aren't effective in CPU load :)

so you have to change code line
[[ "$(pgrep scummvm)" ]] && pkill scummvm
or if you are just a killer without p
[[ "$(pgrep scummvm)" ]] && kill "$(pgrep scummvm)"

Sorry for being inconvinient

@meleu @barrymossel @lostless
I think that's it

[[ "$(pgrep -P $emupid)" ]] && kill $(pgrep -P $emupid)

So I would push to v1.58 give this a try! I tested with a bash that called a bash.... It worked great so far!

I also updated the ES PID detector. It shows emulator call PID, PID of child processes and ES PID! @barrymossel You can use the PID detector to proof if all PIDs will be proper detected!

So go... kill'em all (METALLICA??)

Will try tonight, when I find the time...! :)

@barrymossel please test this one: https://ghostbin.com/paste/adsrw

It has the same logic as the solution above by @cyperghost , I just cleaned up the code. He will update his post soon.

cyperghost

@meleu I agree - I think version 1.59 is a final version now.
But please correct your ghostbin bash... there are small errors in... $emucall isn't definated - it should rather be $emupid

@barrymossel It doesn't matter if you use 1.58 or 1.59. The logic is the same only the style of coding is different.

Feel free to upgrade to v1.59 -- Final version

fixed! thanks!

emucall is emucall and emupid is emupid. ;-)

cyperghost

@meleu
No problem brother. I corrected it but used only emupid as variable :)
But it is better to repost code according to your latest changes. So there is one version 1.59 around

About using variables? You see I'm avoiding these and use just a bunch of them...
Is there any difference? Speed up? Memory usage?

I know it's better for clear code reading.... but is that effcient?

barrymossel

Sorry guys, I was busy drinking last night so I didn't test yet. Probably won't this evening. Will test later this weekend, but I am sure it works with the two of you working on it :)

barrymossel

Yup, seems to work. Thanks guys!

@meleu @cyperghost Hey, somthing has happened. The script no longer works in retroarch. This is recent as I just updated and a week ago it worked. so Kodi it kills, and will shutdown emulation station properly if its open, but will no longer kick retroarch back to emulation station to exit. It just says terminated and shuts down without saving meta data. Looks like it just gives up and does the old way of shutting down. also @cyperghost , my reset on my nespi no longer works with retro arch, kodi is fine, because of what ever has happened. WHY DID I UPDATE!!!!! LOL

meleu

@lostless can you please try this approach here?: https://retropie.org.uk/forum/topic/12895/ensuring-es-gracefully-finish-and-save-metadata-in-every-system-shutdown

lostless

@meleu I’ll take a look when I get home. Just To Verify, this is what I have running in my script. Is this the most up to date?

#!/bin/bash
# Terminate any emulatorcall!
# This works just for RetroPie!

 emucall="$(sed -n 4p /dev/shm/runcommand.info | tr -d '\\"' | tr '^$[]*.()|+?{}' '.')"
        if [[ -n "$emucall" ]]; then
            emupid="$(pgrep -f "$emucall")" 
            pkill -P "$emupid"
            kill "$emupid"
            sleep 4
        fi

cyperghost

@lostless Please use the approach @meleu posted...
The coding is the same but you don't need to modify the shutdown script itself!

meleu

@lostless please, when posting a code like that put it beetween codeblocks. More info here: http://commonmark.org/help/

lostless

Looks like I’m missing the “wait”at the end compared to the script I use for the reset button. I’ll add it in and see if it helps. The issue I’m having though is not meta data related. As I said. When in ES, it funtions fine. It’s just when in retroarch that it no longer exits back to ES. Kodi is fine. It was working fine until yesterday.

@meleu heres the script im using now, same issue

#!/bin/bash
# Terminate any emulatorcall!
# This works just for RetroPie!
emucall="$(sed -n 4p /dev/shm/runcommand.info | tr -d '\\"' | tr '^$[]*.()|+?{}' '.')"
# If there's an emulator running, we need to kill it and go back to ES
if [[ -n "$emucall" ]]; then
    emupid="$(pgrep -f "$emucall")" 
    pkill -P "$emupid"
    kill "$emupid"
    wait "$emupid"
    sleep 5 # maybe it can be lesser
fi

and errors im getting trying to exit out of retroarch

pkill: killing pid 1 failed: Operation not permitted
pkill: killing pid 2 failed: Operation not permitted
./exit.sh: line 9: kill: `': not a pid or valid job spec
./exit.sh: line 10: wait: `': not a pid or valid job spec

meleu

@lostless are you able to access your raspi via SSH while running an emulator?

If yes, I would like to ask you to do this:

launch a game.
access your raspi via SSH.
perform this command:

bash -x /path/to/the/emulator/killer/script.sh 2> debug.txt

The command above generates the debug.txt file. Post this file on ghostbin or something similar.

Thanks.

Just want to say thanks for all your help.
