Description Craig Donnelly 2016-10-14 21:37:43 UTC 
Description of problem:
The cron.weekly job put in place to clean empty puppet environments will now have situations where there are no KT_* environments to clean up. In this situation, the find command fails and an error is output. We should redirect the errors to null (hide them) or come up with a different command.

Version-Release number of selected component (if applicable):
Satellite 6.2.2.1

How reproducible:
100%

Steps to Reproduce:
1. Install Satellite 6.2
2. Have no publshed puppet environments. (KT_* folders are no longer created for content-views, so on if not modules are published)
3. Run /etc/cron.weekly/katello-clean-empty-puppet-environments

Actual results:
find: ‘/etc/puppet/environments/KT*’: No such file or directory

Expected results:
No errors from script output

Additional info:
Since the only purpose is to clean out unused puppet environments, we could simply add '> /dev/null 2>&1' to the end of the scripts `find` command.
Comment 1 James Hartsock 2016-10-14 21:43:51 UTC 
better than ignoring possibly legitimate errors would be to check for the existence of the directory before doing the find.
Comment 2 Craig Donnelly 2016-10-14 23:09:18 UTC 
Sure thing,

We can go this route instead:

#!/bin/bash

if [ -d /etc/puppet/environments ];then
  if ls /etc/puppet/environments | grep KT; then
    find /etc/puppet/environments/KT* -maxdepth 0 -type d -empty -delete
  fi
fi
Comment 3 Craig Donnelly 2016-10-14 23:33:24 UTC 
This has actually already been taken care of upstream.
The new cron looks like this:

$ cat katello-clean-empty-puppet-environments
#!/bin/bash

# Puppet 4
[ -d /etc/puppetlabs/code/environments ] &&  find /etc/puppetlabs/code/environments/KT* -maxdepth 0 -type d -empty -delete

# Puppet 3
[ -d /etc/puppet/environments ] && find /etc/puppet/environments/KT* -maxdepth 0 -type d -empty -delete

This just needs to be pulled down into Satellite 6.2.
