Issue #19871 has been updated by Henrik Lindberg.
It would be possible to catch errors in the functions template() and
inline_template and translate them to something else than ParseError.
I don't understand the use case though - seems like the right thing to do would
be to construct the manifests to not generate templates in certain situations.
Is that not possible in this case?
Or is this a matter of lazy evaluation? e.g. content => template('foo'), and
the resource state does not really require the content?

Feature #19871: Templates Shouldn't Cause Runs To Fail

----------------------------------------
A customer submitted the following feature request:
Currently all templates are generated during catalog compilation phase. If for
whatever reason any template cannot be generated fatal error is thrown and
Puppet fails during catalog compilation - nothing gets done. This seems like a
design flaw to me as sometimes on purpose we do not want to generate template
if eg. certain fact is not present (so file does not get updated) whereas we
still want to be able to run Puppet to eg. fix the issue. This easily can lead
to deadlock situations when certain template cannot be generated because
certain fact is not present and Puppet run is required to cure it. Would it be
possible to fail templates in the very same manner as other resources (eg.
files), so only dependent resources get affected and not everything.
