Yes. Errors bubble from sql_xlat up to the update section. If the value
returned from the SQL statement is empty, a zero length attribute will be
created, as with 2.x.x, provided that the statement completed successfully.
To support the above, all xlat functions now return an ssize_t, where >= 0 is
success (length of data written to buffer), and < 0 is failure.
As of a couple of minutes ago, an update section will now return two RLM_*
codes, RLM_MODULE_FAIL if something has actually failed and RLM_MODULE_INVALID
if an attribute or list was referenced that doesn't exist in the current
request.
