At the very top of the main ikiwiki executable script the PATH environment is set like this:
$ENV{PATH}="/usr/local/bin:/usr/bin:/bin:/opt/local/bin";
This makes it a little hard to specify which specific binaries should be used, especially if there is more than one of them available (see c.f. http://trac.macports.org/ticket/26333 where the MacPorts-supplied, up-to-date subversion should be used and not an arcane one from the base distro / OS). Is there a specific reason why ikiwiki wipes out $PATH like this or could that line be improved to
$ENV{PATH}="$ENV{PATH}:/usr/local/bin:/usr/bin:/bin:/opt/local/bin";
? The alternative is of course to patch ikiwiki as suggested in the bug, but I wanted to ask here first :)
You can use the ENV setting in your setup file to set any environment
variables you like. Since ikiwiki.cgi is run by the web browser, that
is the best way to ensure ikiwiki always runs with a given variable set.
As a suid program, the ikiwiki wrappers have to sanitize the environment.
The ikiwiki script's own sanitization of PATH was done to make perl taint
checking happy, but as taint checking is disabled anyway, I have removed
that. [[done]] --[[Joey]]
