Heavy refactoring in parts of conf.c. init_conf() parse_boolean() parse_list_file() Re-arrangement of code. parse_address_glob_list() Removed unneccessary parameter. parse_list() parse_interface(): Use strtok()/strchr() instead of doing is all by hand. Removed limitation of fixed size buffer. eat_comments() Use a state machine. eat_line_trailing() eat_spaces() read_lval() Better structured code. read_conf() read_route() Removed magic numbers. Made all list type in the config files accept pathname entries, except for `permanent_routes' and `query_routes.' for which this is impossible.
