Daemon is crashing

[tibaultbordeaux]

Dear Claude,

I tried pi-timolo again after a long time, but without success. I'm on a Raspberry Zero W with a fresh RaspberryPi OS Buster Full sudo apt-get update/upgrade was done then installed latest version of pi-timolo

I also did this:

sudo chown -R pi:pi /home/pi/pi-timolo/*

pi-timolo.py and webserver.py are working fine. But when using *.sh to start the daemons, the background tasks are crashing immediately:

pi@rpi-zero:~/pi-timolo$ ./pi-timolo.sh start
./pi-timolo.sh ver 1.1 written by Claude Pageau
-----------------------------------------------
START   - Start /home/pi/pi-timolo/pi-timolo.py in Background
STATUS  - Waiting 10 seconds ....
STATUS  - pi-timolo.py is Running ...
STATUS  - PID is 2345
INFO    - To Stop pi-timolo.py execute command below
INFO    - ./pi-timolo.sh stop
pi@rpi-zero:~/pi-timolo$ ./pi-timolo.sh status
./pi-timolo.sh ver 1.1 written by Claude Pageau
-----------------------------------------------
STATUS  - pi-timolo.py is Not Running ...
INFO    - To Start pi-timolo.py execute command below
INFO    - ./pi-timolo.sh start

Do you have any hints for me?

[Update] It seems to work for me after editing *.sh. Adding "python" in front of the command did the trick:

python $progpath/$progname >/dev/null 2>&1 &

Is this a proper way of solving the issue? [/Update]

run pi-timolo.py directly and see what log messages appear. This will allow you to diagnose the problem. May be due to a library issue or camera problem

cd ~/pi-timolo

./pi-timolo.py

If you cannot diagnose problem from log messages then send me log and I will help

Dear Claude, thanks for your fast reply! I did try running pi-timolo.py before and it works flawlessly. I do not get any error messages. Same with webserver.py.

Probably it wasn't a good idea to update my original post, as you might not have seen the update:

Adding "python" in front of the command in pi-timolo.sh like this ...

python $progpath/$progname >/dev/null 2>&1 &

is a working solution for me. However, this does not seem to work within webserver.sh. It's wierd.

Ok, maybe I'm getting closer. When starting ./pi-timolo.py within the directory pi-timolo everything is working fine.

But when starting from outside of this directory, i.e. by using /home/pi/pi-timolo/pi-timolo.py

I get this error:

[Errno 2] No such file or directory: 'media/shortl'

[tibaultbordeaux]

Ok, here is my next update. I got rid of the above error message when using the full path in config-file, i.e. /home/pi/pi-timolo/media/shortl

Next step was adding "python3" instead of "python" in webserver.sh.

The situation now is like this: I still get

STATUS  - pi-timolo.py is Not Running ...

but: pi-timolo is working now.

If you change the location of the pi-timolo install directory you will need to change some bash script variables eg in pi-timolo.sh. In order for bash scripts to run pi-timolo.py in the background it needs an absolute path since background shell may not have a path variable. That means some of the shell scripts would need the progpath variable edited. This is the default for pi-timilo.sh where progpath variable would need to be edited. Note the quotes must be included and no space after the =

progpath="/home/pi/pi-timolo"

progname="pi-timolo.py"

Here is the default for webserver.sh where progpath variable would need to be edited

progpath="/home/pi/pi-timolo"

progname="webserver.py".

Note these scripts are only used to start background tasks.

For more info on absolute vs relative paths see https://www.computerhope.com/issues/ch001708.htm https://www.computerhope.com/issues/ch001708.htm

If you think things are really messed up, you may want to consider deleting your current installation and do a fresh install. and run from default location. If you want to run pi-timolo from a mounted hard disk or thumb drive see wiki https://github.com/pageauc/pi-timolo/wiki/How-to-Run-Pi-Timolo-from-Another-Directory-Path https://github.com/pageauc/pi-timolo/wiki/How-to-Run-Pi-Timolo-from-Another-Directory-Path Let me know how you are doing. Stay Safe Claude ...
