location 6.x-3.0-rc2

This is mainly released now because people keep running into #317998: preg_match() expects parameter 2 to be string, array given w pliku /mydrupaldir/includes/bootstrap.inc, linia 670. and re-reporting it.

Changes since DRUPAL-6--3-0-RC1:

• Although I can't fix the update warnings proper, I can inform the user why they happen, reduce them, and repair the stuff reported in #317823.
• #317998 by szy, mburak: Don't attempt to tokenize arrays.
• #142272 by thierry_gd: Better province names for Provence-Alpes-Cote d'Azur in location.fr.inc.
• Add function location_province_code().
• Fix $op 'delete' on hook_locationapi().
• API CHANGE: Use location_save_locations() with an empty array instead of deleting rows from {location_instance}. This lets us have "real" deletion instead of relying on garbage collection.

  Before:
  

  db_query("DELETE FROM {location_instance} WHERE genid = '%s'", 'mykey:'. $obj->id);

  After:
  

  $locations = array();
location_save_locations($locations, array('genid' => 'mykey:'. $obj->id));
• Remove garbage collection routine and UI from settings page. References are checked automatically now.
• Slight fix to #305474, noticed by sterwa: Change the second 'ro' in the list to 'ru'.
• Pull the new location_search.module from DRUPAL-5--3 in preparation for D6 porting.
• Port the new location_search module to Drupal 6.
• Remove undefined variable.
• Add a function, location_check_coordinates(), to centralize the emptiness checks.
  Fix map centering when editing locations with LOCATION_LATLON_UNDEFINED coordinates.
