[vdr] SVDRP - problems when 2 sends nearly at same time -> e.g. vdradmindisturbs sleeptimer

[e-PUNK@gmx.de]

Hi,

I'm using stable vdr 1.2.6.

The following commandline demonstrates a problem, that lets e.g. the 
sleeptimer-plugin not work correctly in conjunction with vdradmin. 
(Well, thats what I think the problem is, cause there are no 
errormessages from sleeptimer)

i=0;  while true; do svdrpsend.pl MESG $i &  sleep 2 ; i=$((i+1)) ; done

/var/log/syslog:

Ok that looks good, but an the TV not every message is shown!

Why is this a problem?
I have vdradmin running. That does a svdrp connect every minute or 
something to read the epg or what ever. Now, when I set a sleeptimer 
with sleeptimer-plugin, it could happen, that the vdr does not shutdown. 
The sleeptimer-plugin simply is running a script like the following when 
the time I configured as sleep-time is over:

sleeptimer.sh:

#!/bin/sh
echo "svdrpsend.pl HITK Power" | at now

Like with the example above this svdrpsend command could have been 
ignored by vdr and the system does not shutdown. The workaround could be 
to call a sleeptimer2.sh via atd :

sleeptimer2.sh:

#!/bin/sh
i=10
while test $i -gt 0 ; do
svdrpsend.pl HITK Power
sleep 5
i=$((i-1))
done

But I think, that's a bit dirty.
I know, making svdrpsend queueing all commands ever send, could have 
other bad effects. E. g. when doing the first example without the "sleep 
2" . So what are your opinions about that problem?

Marten
