Description

I just had this strange error

Problem parsing /var/www/html/psalm.xml: Could not resolve config path to /var/www/html/

thrown from here.

The cause was this snippet in my psalm.xml:

        <RedundantConditionGivenDocblockType>
            <errorLevel type="suppress">
                <directory name="bar/"/>
            </errorLevel>
        </RedundantConditionGivenDocblockType>

I just had moved bar to foo/bar. So it could not resolve bar (realpath in Line 168 returned false). That was hard to find because the error was not very informative. Maybe we could change that so that I can see the real mistake a bit more clearly? 😅

Research direction
Improve the error message in FileFilter.php when realpath returns false, so that the non existent directory name is shown.
