I've just built the latest 3 from GIT:

and with the default includes/rmdir.inc
f001:~ # cat /etc/robinhood.d/includes/rmdir.inc
# used to be rbh 2.5 "rmdir" policies in TMPFS mode
define_policy rmdir_empty {
scope {type == directory and dircount == 0}
status_manager = none;
default_action = common.rmdir;
default_lru_sort_attr = last_mod;
}
define_policy rmdir_recurse {
scope {type == directory}
status_manager = none;
default_action = cmd("rm -rf {fullpath}");
default_lru_sort_attr = last_mod;
}
I'm seeing SQL syntax errors with a very simple rmdir_empty_rules:
rmdir_empty_rules {
ignore { owner == root or depth < 2 }
rule default {
condition { last_mod > 4d }
}
}
rmdir_empty_parameters {
lru_sort_attr = none;
}
rmdir_empty_trigger {
trigger_on = periodic;
check_interval = 12h;
}
f001:~ # robinhood --run=rmdir_empty --once

which seems to be caused by the excessive ((( on the sql: - typing
verbatim into SQL query:
MariaDB [rbh_scratch]> SELECT ENTRIES.id AS id FROM ENTRIES WHERE
ENTRIES.type='dir' AND (ENTRIES.invalid=0 OR ENTRIES.invalid IS NULL)
AND (ENTRIES.last_mod<1491055908 OR ENTRIES.last_mod IS NULL) AND NOT
(((ENTRIES.uid='root' OR ENTRIES.uid IS NULL) LIMIT 100000;
ERROR 1064 (42000): You have an error in your SQL syntax; check the
manual that corresponds to your MariaDB server version for the right
syntax to use near 'LIMIT 100000' at line 1
and limiting the returned limit slightly gives same error as expected
MariaDB [rbh_scratch]> SELECT ENTRIES.id AS id FROM ENTRIES WHERE
ENTRIES.type='dir' AND (ENTRIES.invalid=0 OR ENTRIES.invalid IS NULL)
AND (ENTRIES.last_mod<1491055908 OR ENTRIES.last_mod IS NULL) AND NOT
(((ENTRIES.uid='root' OR ENTRIES.uid IS NULL) LIMIT 10;
ERROR 1064 (42000): You have an error in your SQL syntax; check the
manual that corresponds to your MariaDB server version for the right
syntax to use near 'LIMIT 10' at line 1
but changing ((( -> ( works

I can't see where this is defined in the source, to submit a patch I'm afraid
