Handle DNS errors and other network failures #3
Description
Output sent to me via cron email:
/etc/cron.daily/email_updates: https://cdn.redhat.com/content/dist/rhel/server/5/5Server/x86_64/cf-tools/1/os/repodata/repomd.xml: [Errno 4] IOError: Trying other mirror. https://cdn.redhat.com/content/dist/rhel/server/5/5Server/x86_64/rhev-agent/3/os/repodata/repomd.xml: [Errno 4] IOError: Trying other mirror. https://cdn.redhat.com/content/dist/rhel/server/5/5Server/x86_64/os/repodata/repomd.xml: [Errno 4] IOError: Trying other mirror. SQL error: near "Temporary": syntax error
The email notification contained a body that looked like this:
-3,-'Temporary Hostname: X.X.X IP Address(es): ---------------------------------- X.X.X.X
My first thought is that this situation should be treated the same as if there were no updates at all and not reported. Or at the very least let cron catch the errors and skip sending an email notification. That way whatever ticketing system that catches the emails won't create invalid tickets.
