Hi Guys,
I wrote a few scripts to monitor an uploads directory for changes, then capture the file uploaded/changed and push it to cloud files using a ruby script. This all works well 95% of the time, the only exception is that occasionally, ruby fails with a 'file does not exist' exception.
I am assuming that the ruby 'push' script is being called before the file is 100% in its new location, so the script is being called a little prematurely.
I tried adding a little function to my script to check if the file exists, if it doesn't, sleep 5 then try again, but this seems to snowball and eventually dies. I then just added a sleep 2 to all calls, but it hasn't helped as I now get the 'file does not exist' error again.
#!/bin/sh
function checkExists {
if [ ! -e "$1" ]
then
sleep 5
checkExists $1
fi
}
inotifywait -mr --timefmt '%d/%m/%y-%H:%M' --format '%T %w %f' -e modify,moved_to,create,delete /home/skylines/html/forums/uploads | while read date dir file; do
cloudpath=${dir:20}${file}
localpath=${dir}${file}
#checkExists $localpath
sleep 2
ruby /home/cbiggins/bin/pushToCloud.rb skylinesaustralia.com $cloudpath $localpath
echo "${date} ruby /home/cbiggins/bin/pushToCloud.rb skylinesaustralia.com $cloudpath $localpath" >> /var/log/pushToCloud.log
done
I am looking for any suggestions to help me make this 100% stable (eventually, I'll serve the uploaded files from Cloud FIles, so I need to make sure its perfect)
Thanks in advance!
