From client version 150701 as well as kernel version 150701, the watched files are being sent in BASE64 encoding, allowing to transfer other than UTF-8 encoded text files.
That means this feature can be used to watch and transfer changes in workers.txt to clients over CNP connection.
Add this to kernel config file:
watch/workers = /usr/local/plc/lib/workers.txt
Make sure workers.update on kernel does not replace workers.txt with temporary file but truncates it instead, i.e. this is wrong:
mv -f /usr/local/plc/lib/workers.txt.tmp /usr/local/plc/lib/workers.txt
and this is correct:
cat /usr/local/plc/lib/workers.txt.tmp > /usr/local/plc/lib/workers.txt rm -f /usr/local/plc/lib/workers.txt.tmp
Don't forget to remove workers.update from cron on all stations.
