hook_uninstall() is incomplete

Because DFF is still in dev status, this should probably be a feature request.

Uninstalling DFF does drop the tables, but not all the other stuff that got written to the database. After messing up my Facebook Connect Block (i changed the default Title to <none>), the block disappeared for good. Clearing Caches, Cookies, Sessions, deleting the FB app, logout from FB, ... plus deleting all entries from authmap that contained "@facebook.com" was not enough to fix this problem.

Performing a search for "fb_" in phpmyadmin, and deleting all the stuff beginning with "fb_" did it. I was able to create a new FB app and now the Connect Block is showing and working.

I don't know which submodule needs what:

function fb_uninstall() {
  // probably fb_uninstall() of fb_app
  $fb_apps = db_query("SELECT nid FROM {node} WHERE type = 'fb_app'");
  while ($fb_app = db_fetch_object($fb_apps)) {
    node_delete($fb_app->nid);
  }

  // probably fb_uninstall() of fb_devel
  db_query("DELETE FROM {blocks} WHERE module = 'fb_devel'");

  // probably fb_uninstall() of fb_connect
  db_query("DELETE FROM {blocks} WHERE module = 'fb_connect'");

  // probably fb_uninstall() of fb_connect
  variable_del('fb_connect_primary_apikey');

  // probably fb_uninstall() of fb_connect
  $result = db_query("SELECT sid FROM {sessions} WHERE sid LIKE 'fb_connect_%'");
  while ($row = db_fetch_object($result)) {
    db_query("DELETE FROM {sessions} WHERE sid = '%s' LIMIT 1", $row->sid);
  }

  // probably fb_uninstall() of fb_connect
  $result = db_query("SELECT authname FROM {authmap} WHERE authname LIKE '%facebook.com'");
  while ($row = db_fetch_object($result)) {
    db_query("DELETE FROM {authmap} WHERE authname = '%s' LIMIT 1", $row->authname);
  }
}
