Title:
  Document module migration of "url" attachments

Status in OpenERP Modules (addons):
  Fix Committed

Bug description:
  Hello,

  On trunk (same problem in stable 6):
  In the document module, in document.py there is a method _attach_parent_id to migrate documents on the installation of the module.

  The query :
  cr.execute("UPDATE ir_attachment SET file_size=length(db_datas) WHERE file_size = 0;")
  will work only for attachments of type "binary", for those one of type "url" it will raise a not null constraint error and block the module installation :
  ERROR:  null value in column "file_size" violates not-null constraint
  Because length() of an empty column returns null.

  To fix, replace the query by:
  cr.execute("UPDATE ir_attachment SET file_size=length(db_datas) WHERE file_size = 0 and type = 'binary';")

  Thanks
  Regards
  Guewen
