Relative module import and controller.xql , was: XQueryURLRewrite implementation change proposal

Wolfgang,

The implementation of the multiple controller.xql is really useful. The only
small inconvenience to use this feature is the fact the if any modules are
imported by controller.xql, we still need to specify the full path of the
module relative to webapps. It would have been much easier if the controller
picks up the modules from the same directory.
The good news is that the relative import paths already have been
implemented (Patch #2812962) and I was wandering if there is any chance to
include the relative module import in the coming release.

Regards,
Thomas

I implemented your proposal in rev 9247. XQueryURLRewrite can now scan
the directory or collection hierarchy to find a controller.xql which
matches the request path. For example, if the requested path is
/exist/a/b, XQueryURLRewrite will check the directories webapp/a and
webapp/a/b for an XQuery file called controller.xql and executes the
last one it finds.

The start point for the search is determined by configuration
parameter "base" in web.xml. This parameter can also point to a
collection in the db, causing XQueryURLRewrite to search the
collection hierarchy instead of the file system.

    <filter>
        <filter-name>XQueryURLRewrite</filter-name>
        <filter-class>org.exist.http.urlrewrite.XQueryURLRewrite</filter-class>
        <init-param>
            <param-name>base</param-name>
            <param-value>xmldb:exist:///db</param-value>
        </init-param>
    </filter>
