FYI.... I was having problems when I used the "matches" expression in filters. For example: I set PurgeWhenFull filter to only delete <Name><matches><Event> because if I renamed an event, I probably wanted to keep it. However, the matches clause would cause a sql error. I fixed the error by adding single quotes around the $value variable in filter.pl.

Changed from this:

Code: Select all

if ( $filter_terms{$op_name} eq '=~' )
                                {
                                        $filter_sql .= " regexp $value";
                                }
                                elsif ( $filter_terms{$op_name} eq '!~' )
                                {
                                        $filter_sql .= " not regexp $value";

                                {
                                        $filter_sql .= " regexp '$value'";
                                }
                                elsif ( $filter_terms{$op_name} eq '!~' )
                                {
                                        $filter_sql .= " not regexp '$value'";

I thought that I could place single quotes around the <Event> text in the filter window but this would not work. I found that I had to place the quotes in the PERL script.

you do realize there is an archive function that will save events until you delete with out your creative query

on top of event window there is a button called archive

Yes, I know this. In fact my PurgeWhenFull filter has a condition of 'NotArchived', however I set the 'creative query' condition because if I saw an event and changed the name but did not archive it, the event won't be deleted. Sort of a failsafe for not deleting important events.
