Hello,

I'd like to add the tests-common*() family of functions to the
eclass/tests/tests-common.sh file as required for clean (garbage-free)
run of scons-utils tests.

I'm attaching the patch. Does anyone have any objections or
suggestions? The code was based on one used in Portage.

use explicit -n here, although this could give incorrect behavior. better to
use [[ $# -gt 0 ]].

if you're going to use [[]], then also use ==

this whole func is overkill. just use a single printf:
[[ $# -eq 0 ]] && return 0
if [[ ${ECLASS_DEBUG_OUTPUT} == "on" ]] ; then
printf 'debug: %s
' "$@" >&2
elif [[ -n ${ECLASS_DEBUG_OUTPUT} ]] ; then
printf 'debug: %s
' "$@" >> "${ECLASS_DEBUG_OUTPUT}"
fi

debug-print ${1}: entering function, parameters: ${*:2}"

True.

Pointless. == implies pattern matching.

I agree but I assumed Portage behavior has some reason for it. Maybe
it's some kind of pseudo-multiline output?

debug-print 'line1'
'line2'

where each line would be prefixed with 'debug:'.

That printf expression does the exact same thing, printing each argument
on a separate line, prefixed with 'debug: '.

Ah, I wasn't aware of that printf behavior. My mistake then.

not really. the point of using == is to avoid confusion of assignment
which = implies.
