[Bro] Load Single Column Table with Input Framework

[Azoff, Justin]

The table doesn't get loaded immediately.  There is an "input file loaded" event you can print from, or for testing try using bro_done

I'm following the tutorial on the input framework:
http://www.bro.org/sphinx/input.html

Everything works great.  But, if my blacklist is only one column (i.e. I remove the other columns so that I'm only left with the "ip" column), I run into issues.

The docs for Input::add_table say that val is optional:
<quote>
val: any &optional

Record that defines the values used as the elements of the table If val is undefined, destination has to be a set.
</quote>

So, I fixed my script to look like this:
<new_script>

type Idx: record {
        ip: addr;
};

global blacklist: set[addr];

event bro_init() {
        Input::add_table([$source="blacklist.file", $name="blacklist", $idx=Idx, $destination=blacklist]);
        print(|blacklist|);
        Input::remove("blacklist");
}

</new_script>

No more val and changed the table to a set of addr.

The size for blacklist that gets printed out is 0, even though blacklist.file looks like this:

<blacklist.file>
#fields ip
#types  addr
192.168.17.1
192.168.27.2
192.168.250.3
</blacklist.file>

I expected print(|blacklist|) to print out 3.

I know I must be missing something simple.  What am I missing?  How should I read in a single column table?
