annotate backend/contrib/shpimporter/hws.py @ 9713:aef987124822 3.2.x

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Do not rely on database default for setting hws_lines.official to 0 It's not under the control of the importer whether the field is rendered into an INSERT statement, whether it's actually set or not. If it is unset but rendered into the statement, the field would be set to NULL. Thus, always set it explicitly. While here, remove an unused import.
