NAME

6       Mail::SpamAssassin::BayesStore::MySQL - MySQL Specific Bayesian Storage
7       Module Implementation
8

DESCRIPTION

10       This module implements a MySQL specific based bayesian storage module.
11       It requires that you are running at least version 4.1 of MySQL, if you
12       are running a version of MySQL < 4.1 then several aspects of this
13       module will fail and possibly corrupt your bayes database data.
14
15       In addition, this module will support rollback on error, if you are
16       using the InnoDB database table type in MySQL.  For more information
17       please review the instructions in sql/README.bayes.
18
19       This module is also compatible with MariaDB and DBD::MariaDB can be
20       used instead of DBD::mysql driver.

71
72   nspam_nham_change
73       public instance (Boolean) nspam_nham_change (Integer $num_spam,

89                                            String $atime)
90
91       Description: This method does a mass update of the given list of tokens
92       $tokens, if the existing token atime is < $atime.
93
94       The assumption is that the tokens already exist in the database.
95
96       We should never be touching more than N_SIGNIFICANT_TOKENS, so we can
97       make some assumptions about how to handle the data (ie no need to batch
98       like we do in tok_get_all)
