How can I subclass DBI to hide user credentials?

Question

I want to subclass the DBI module to hide the connect subroutine with C code. For example, I have:

$dbh = DBI->connect($data_source, $username, $auth, \%attr);

I want to write some C code which calls the above DBI->connect subroutine and returns the $dbh handle in Perl.

Is that possible to do and if so, could someone provide an example or point to some sources?

Answer 1

Why subclass? Just create a sub!

sub my_connect {
   # Get from config file or whatever
   my $user   = ...;
   my $passwd = ...;

   return DBI->connect($data_source, $username, $auth, \%attr);
}
