Yes, it is true that this happens only when running gitweb as mod_perl legacy script using ModPerl::Registry. Otherwise it would be caught when running t/t9500-gitweb-standalone-no-errors.sh test. > > Will it also not complain if I provided my own $projects_list in the > first place? Yes, it would not, because the code is run only when $projects_list is a directory to search for git repositories. If $projects_list is a file you wouldn't get this warning (and it might be slightly faster, if less flexible, as you would need to regenerate this file when adding or removing, or renaming, or changing owner of repositories). -- Jakub Narebski Poland -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
