How to check return values of Jena components

["Neubert, Joachim" <J....@zbw.eu>]

In my tdb create script, I have several steps (loading, text indexing etc.) building on each other, and I want the whole script to abort when an error occurs. Therefore, I've introduce return value checks like this:

# since output is piped to tee, the return value of the originating program
               # has to be considered
               set -o pipefail

$JENAROOT/bin/tdb2.xloader $XLOADER_OPTS --loc=/var/lib/fuseki/databases/temp $FILE 2>&1 | tee -a $LOG
               if [ $? -eq 0 ]
then
echo `date +"%Y-%m-%d %T"` finished loading $FILE >> $LOG
echo "" >> $LOG
else
echo `date +"%Y-%m-%d %T"` ABORTED >> $LOG
exit 1
fi

               # ...

               # text indexing

With tdb2.xloader as well as fuseki jena.textindexer, I got the ABORTED, though apparently all went well.

Probably I make a simple fault here, but I couldn't figure out.

Cheers, Joachim

Hi Andy, when I tried to reproduce the issue with a small file, all worked find, the return value is 0. I will now load GND, and see if it can be reproduced with with a larger file. Cheers, Joachim

Hi Joachim,

Using the development build, I get a return code of 0 from xloader. (The 
release one is broken)

What return code are you getting back?

Anything else in the log?
