Greetings, wise monks,

I am trying to crank down restrictions on an FCGI script. I have DBI opening an SQLite3 database as read-only. This is how I am currently connecting to the database: 

    my $dbh = DBI->connect("dbi:SQLite:dbname=$database", 
                undef, 
                undef, 
                { 
                  AutoCommit => 0,
                  RaiseError => 1,
                  on_connect_do => "PRAGMA foreign_keys = ON",
                  sqlite_open_flags => "DBD::SQLite::OPEN_READONLY",
                })
        or die("Could not open database '$database': $!\n");

However, AppArmor still gives the following error about needing write access, even though the error and restrictions causing it do not impair the script from appearing to work as expected:

and in the AppArmor profile: 

        /var/www/db/foo.sqlite3 kr,

If I add w to that, the errors go away. However, I don't want to do that because the script's access is supposed to remain read-only. Yet it appears that DBI is somehow still requesting some kind of write access, even if it does not use it. What can I change in the DBI connection to ensure that it is purely read-only as far as the database goes?
