Good thinking. I guess the best way to find out is to convince somebody from msysgit to try this patch. :) We may simply find that nobody there even has apache installed on their box, and they do not run the http tests at all. -- >8 -- The SANITY prerequisite is really about whether the filesystem will respect the permissions we set, and being root is only one part of that. But the httpd tests really just care about not being root, as they are trying to avoid weirdness in apache (see a1a3011 for details). Let's switch out SANITY for a new NOT_ROOT prerequisite, which will let us tweak SANITY more freely. We implement NOT_ROOT by checking perl's "$>" variable, since we cannot rely on the "id" program being available everywhere (and we would rather avoid writing a custom C program to run geteuid if we can). Note that we cannot just call this "ROOT" and ask for "!ROOT". The possible outcomes are: 1. we know we are root 2. we know we are not root 3. we could not tell, because perl was not installed or barfed showing us $> We should conservatively treat (3) as "does not have the prerequisite", which means that a naive negation would not work.
