210c119907The JSON/CSV branch used 'fn(doc) or doc', so any falsy result was
discarded and the unconverted row inserted. Exit code 0, no warning:
$ echo '[{"id": 1, "name": "Cleo"}]' | sqlite-utils insert d.db t - --convert '{}'
$ sqlite-utils 'select * from d.db' # -> the original row, not {}
The realistic shape of this is a filter:
--convert 'row if row["ok"] else {}' # meant to drop the bad rows
# every row inserted, including the ones meant to be dropped
'--lines' runs a different expression twelve lines up and has no such
fallback, so the same --convert code is rejected there and silently
accepted here:
--convert 0 JSON input -> exit 0, rows inserted
--convert 0 --lines -> exit 1, Rows must all be dictionaries, got: 0
test_insert_convert_error_messages already asserts that a non-dict
return is rejected (--convert 1); 0, False, [] and "" were the outliers,
purely because they are falsy.
None is the one falsy result that has to keep meaning 'modify doc in
place' - a --convert that is a bare statement returns it, which
test_insert_convert_row_modifying_in_place covers - so the fallback is
now keyed on 'is None' rather than truthiness.
Tests: 7 new cases in tests/test_cli_insert.py, all failing on
