[Bro] Re-reading data in the input framework

[Sheharbano Khattak]

Hi,

I want to test if a table that holds data from an input source file with
the automatic refresh mode "REREAD" reflects changes applied to the source
file. This is what my file looks like

-----------------------------config.bro---------------------------------
module Config;

type Idx: record {
        parameter: string;
};

type Val: record {
        value: string;
};

export {
    global table_config: table[string] of Val;
}

global config_filename = "/usr/local/bro/share/bro/site/botflex/config.txt";

event bro_init() &priority=20
    {
    Input::add_table([$source=config_filename, $name="config_stream",
$idx=Idx,
              $val=Val, $destination=table_config, $mode=Input::REREAD]);
    Input::remove("config_stream");
    }

event Input::update_finished(name: string, source: string)
    {
    # now all data is in the table
    print "Updated";
    print table_config;
    }

event bro_done()
    {
    print "Ending";
    print table_config;
    }
-------------------------------------------------------------------------------------------------------

I do bro -i eth0 config.bro. The first time, the event
Input::update_finished is triggered with the values/indices defined in
config.txt.
Then i manually make some changes in config.txt and save the changes but
Input::update_finished is not triggered. After waiting for several minutes,
i ctrl+c Bro hoping to see the modification in table_config, still it shows
the old values. There is nothing interesting in reporter.log either. What
am i doing wrong?

Thanks.
