Description Ivan Necas 2017-03-07 08:20:49 UTC

It's easy to write a template that would read from STDIN, e.g. following snippet hidden in a longer template

<pre>
grep something
</pre>

would cause indefinite job. The job can be cancelled but the eats resources by sending live updates while it does nothing. We should redirect STDIN to /dev/null when we run the script so such calls would end up with error.

Upstream bug assigned to mhulan

Comment 6 Adam Ruzicka 2017-08-02 13:26:02 UTC

Verified.
Satellite-6.3 Snap 9
Package versions:
satellite-6.3.0-16.0.beta.el7sat.noarch
tfm-rubygem-foreman_remote_execution-1.3.3-1.fm1_15.el7sat.noarch

1) Run "grep something" on a host
2) The job starts
3) The job ends with exit code 1 because grep could find something in empty input
