The original already has the same issue with two entries but this
patch makes it even worse by adding yet another one. The longer the
code follows a bad pattern, the more it encourages future developers
to follow the same bad pattern, and usually the best time to do a
clean up like the following
if test -z "$module_path"
then
for candidate in \
/etc/httpd \
/usr/lib/apache2 \
/usr/lib/httpd \
do
if test -d "$candidate/modules"
then
module_path="$candidate/modules"
break
fi
done
fi
is when you go from 2 to 3. Two points to note are:
- It would be easier to add the fourth one this way
- The explicit "break" makes it clear that the paths are listed in
decreasing order of precedence (i.e. /etc/httpd if exists makes
/usr/lib/httpd ignored even if the latter exists); the original
"test -d X && M=X ; test -d Y && M=Y" gives higher precedence to
the later items but readers need to wonder if it is intended or
the code is simply being sloppy.
Hope this helps.
