I tried passing the following to it:

But it only appears to run xterm. I need to

RM #351: Make sure inbound args are passed through completely.


#1 Updated by Hammel almost 6 years ago

  • Target version changed from 0.9.0 to 0.10.0

Still need to investigate this. However, I got around it for now by having a videofe use a configuration file to enable debugging. That way I don't have to pass command line args to it via appmgr.

Moving to next release.

It may be that the only problem here is that appmgr.sh only reads $1 instead of $* when it tries to grab the payload portion of the request. Everything else in the inbound message processing in appmgr appears to be correct.

I'll test this theory.

Here are some small sample mp4 clips for testing:

Changing from $1 to $* does change the payload sent to appmgr. But it's not clear if this works. Using the sample command doesn't seem to launch the command when passed via appmgr.sh to appmgr. If I type the same command in the xterm console it works.

Here is the actual command I used:

/usr/bin/xterm -display :0.0 -fullscreen -fg black -bg black -e /usr/bin/omxplayer -o hdmi -r /root/clipcanvas_14348_offline.mp4

Ah. It looks like the first arg after the command is being dropped. Here is a sample of the payload making it to appmgr.

/usr/bin/xterm :0.0 -fullscreen -fg black -bg black

The problem here is probably not appmgr.sh, it's probably appmgr but I'll need to dump the payload when it arrives to know for sure.

The problem is two fold:
  1. appmgr.sh needs to pass the entire string to appmgr
  2. matchbox-panel requires the argument to appmgr.sh be enclosed in double quotes

Both of these are easily fixed. The appmgr.sh fix can be put in the repo. The matchbox panel is just a safety note for any future panel apps, though with RM #383 the matchbox panel won't be much of an issue later.

#8 Updated by Hammel over 5 years ago

  • Status changed from In Progress to Closed
  • % Done changed from 80 to 100

appmgr.sh updated and pushed upstream.

Closing issue.
