Bug #2455: Misleading/ambiguous error message on invalid fact code should be
changed

If an invalid custom fact is added to a system Facter seems to have a generic
error:
"Could not retrieve <fact name>: non-sh interpreters are not currently
supported"
To me this error indicates a problem with the interpreter line (first line of
the script), which doesn't apply to Facter scripts as far as I can tell. I've
found two problems that can cause this error:
1) Missing the "setcode do [...] end" stanza
2) Invalid file permissions (chmod 000 test_fact_invalid.rb)
To demonstrate:
------
[facter]# cat test_fact_invalid.rb
#test_fact.rb
Facter.add("test_fact_invalid") do
# setcode do
"test value"
# end
end
[facter]# FACTERLIB=/var/lib/puppet/lib/facter/ facter | grep invalid
Could not retrieve test_fact_invalid: non-sh interpreters are not currently
supported
[facter]# chmod 000 test_fact_invalid.rb
[facter]# FACTERLIB=/var/lib/puppet/lib/facter/ facter | grep test_fact
Could not retrieve test_fact_invalid: non-sh interpreters are not currently
supported
-------
When test_fact_invalid.rb is moved out of the way and only a valid custom fact
remains, the error disappears:
----
[facter]# cat test_fact.rb
#test_fact.rb
Facter.add("test_fact") do
setcode do
"test value"
end
end
[facter]# FACTERLIB=/var/lib/puppet/lib/facter/ facter | grep test_fact
test_fact => test value
[facter]#
-----
I believe a more descriptive error message should be displayed when possible,
or if not possible this message be changed to something even more generic which
might help newbies such as myself debug.
Thanks!
