Bug #14060: exec shell provider does "unexpected" shell quoting
https://projects.puppetlabs.com/issues/14060
Author: Matthew Byng-Maddick
Status: Unreviewed
Priority: Normal
Assignee:
Category: exec
Target version:
Affected Puppet version: 2.7.13
Keywords: exec shell provider
Branch:
The shell provider for the exec resource type (`puppet/provider/exec/shell.rb`)
claims that it tries to mirror the behaviour of the 0.25.x series of
(un-provider-ed) exec types.
Simply put, it doesn't.
It wraps what is supplied in the command in *double* quotes ("") meaning that
expansions of $ and \ take place at the wrong level, and only substitutes out "
with \"
It currently does:
<pre>
def run(command, check = false)
command = %Q{/bin/sh -c "#{command.gsub(/"/,'\"')}"}
super(command, check)
end
</pre>
But should actually do:
<pre>
def run(command, check = false)
command = %Q{/bin/sh -c '#{command.gsub(/'/,"'\"'\"'")}'}
super(command, check)
end
</pre>
Principle of least surprise and all...
