NAME
Mail::SpamAssassin::BayesStore::MySQL - MySQL Specific Bayesian Storage Module Implementation
DESCRIPTION
This module implements a MySQL specific based bayesian storage module. It requires that you are running
at least version 4.1 of MySQL, if you are running a version of MySQL < 4.1 then several aspects of this
module will fail and possibly corrupt your bayes database data.
In addition, this module will support rollback on error, if you are using the InnoDB database table type
in MySQL. For more information please review the instructions in sql/README.bayes.
METHODS
token_expiration
public instance (Integer, Integer,
Integer, Integer) token_expiration(\% $opts,
Integer $newdelta,
@ @vars)
Description: This method performs the database specific expiration of tokens based on the passed in
$newdelta and @vars.
seen_put
public (Boolean) seen_put (string $msgid, char $flag)
Description: This method records $msgid as the type given by $flag. $flag is one of two values 's' for
spam and 'h' for ham.
seen_delete
public instance (Boolean) seen_delete (string $msgid)
Description: This method removes $msgid from the database.
set_last_expire
public instance (Boolean) set_last_expire (Integer $time)
Description: This method sets the last expire time.
set_running_expire_tok
public instance (String $time) set_running_expire_tok ()
Description: This method sets the time that an expire starts running.
remove_running_expire_tok
public instance (Boolean) remove_running_expire_tok ()
Description: This method removes the row in the database that indicates that and expire is currently
running.
nspam_nham_change
public instance (Boolean) nspam_nham_change (Integer $num_spam,
Integer $num_ham)
Description: This method updates the number of spam and the number of ham in the database.
tok_touch
public instance (Boolean) tok_touch (String $token,
String $atime)
Description: This method updates the given tokens ($token) atime.
The assumption is that the token already exists in the database.
tok_touch_all
public instance (Boolean) tok_touch (\@ $tokens
String $atime)
Description: This method does a mass update of the given list of tokens $tokens, if the existing token
atime is < $atime.
The assumption is that the tokens already exist in the database.
We should never be touching more than N_SIGNIFICANT_TOKENS, so we can make some assumptions about how to
handle the data (ie no need to batch like we do in tok_get_all)
cleanup
public instance (Boolean) cleanup ()
Description: This method performs any cleanup necessary before moving onto the next operation.
clear_database
public instance (Boolean) clear_database ()
Description: This method deletes all records for a particular user.
Callers should be aware that any errors returned by this method could causes the database to be
inconsistent for the given user.
Private Methods
_connect_db
private instance (Boolean) _connect_db ()
Description: This method connects to the SQL database.
_initialize_db
private instance (Boolean) _initialize_db ()
Description: This method will check to see if a user has had their bayes variables initialized. If not
then it will perform this initialization.
_put_token
private instance (Boolean) _put_token (string $token,
integer $spam_count,
integer $ham_count, string $atime)
Description: This method performs the work of either inserting or updating a token in the database.
_put_tokens
private instance (Boolean) _put_tokens (\% $tokens,
integer $spam_count,
integer $ham_count, string $atime)
Description: This method performs the work of either inserting or updating tokens in the database.
