data scan bug notes

The bug is in handling multi-line fields in the data_scan module.

On the page: http://bird.org/Fuego_Issue_List there is a database definition with a match_spec that includes a multi-line field (Description). This field is not getting parsed by the routine data_scan:scan_attr_db().

I'm not sure what the syntax is supposed to be for multi-line fields, but here is the current definition in the match_spec:

Description=^= Description =()
Description_endpat=^=()

Location of routines [edit section]

  • in table.py, db_from_parsed_files() calls data_scan.scan_attr_db()
  • in data_scan.py scan_attr_db() calls parse_data()

There's a FIXTHIS line in parse_data that says that multi-line values are not tested.
