Check_bayes sub in Bayes.pm

["Shreyansh Shrivastava." <sh...@nitk.edu.in>]

I am trying to develop a plugin for a SVM classifier. I intend to make it
similar to the Bayes plugin but I couldn't figure out the entry point for
the check_bayes() subroutine. Can anyone help me with this?

When the Mail::SpamAssassin object is initialized, it parses all of the 
.cf files and constructs a subroutine from each "rule" line loaded. See 
Mail::SpamAssassin::Conf::Parser, particularly add_test() and 
finish_parsing().


The rule lines in 23_bayes.cf like this:

body BAYES_00		eval:check_bayes('0.00', '0.01')
body BAYES_05		eval:check_bayes('0.01', '0.05')

are each translated into a test subroutine that calls check_bayes(). The 
pile of subroutines that is constructed from rules is called when 
Mail::SpamAssassin->check() is called, by way of 
Mail::SpamAssassin::PerMsgStatus->check() and 
Mail::SpamAssassin::PerMsgStatus->check_timed().

Does that help?

Check_bayes() is declared in Bayes.pm. An object of Bayes.pm is made in
init() sub of spamassassin.pm but check_bayes() isn't called there.

The 23_bayes.cf file has various configuration for check_bayes() having
different min,max defined. Also check_bayes() is passed to
register_eval_rule() of Conf.pm. I am not able to connect these dots to get
the entry point.
