Rambetter on Sun Jan 23, 2011:
|
|
|
|
What follows is a discussion of the introduction to some new members and functions
|
|
such as baseFilters, baseFilterExcludes, FilterAddImpl(), and so on.
|
|
|
|
There was a problem that "base" filters were not taking effect as a result of
|
|
user action such as clicking a filter checkbox. The reason why the base filters
|
|
were not being updated is because the previous logic of updating the filters had
|
|
been commented out. It was commented out because the previous logic deleted ALL
|
|
filters (including plugin filters) and re-created only the base filters. So in
|
|
effect, all plugin filters would be deleted whenever a filter checkbox was altered.
|
|
|
|
So, we need some way of knowing which are the base filters so that we can take
|
|
action when a filter checkbox is marked [or unmarked]. Then we can update
|
|
the base filters by either deleting and recreating them, or by changing their
|
|
active state in an intelligent manner. I am choosing to do the latter.
|
|
|
|
My goal here is to preserve the structure bfilter_t completely as it has been
|
|
historically. I feel that modifying bfilter_t is dangerous with respect to breaking
|
|
plugins. So what I'm doing instead is tracking which are the base filters via
|
|
external array, baseFilters. The array baseFilterExcludes keeps track of the "exclude"
|
|
parameter for the corresponding filter.
