Re: [Tracker] trackerd restart issue

[jerry tan <Jerry Tan Sun COM>]

I suggest that we can check these values changes case by case:

For Example,
1. If check/uncheck "Enable Evolution mail",
we just need to check if evolution index data existing on database,
if Yes,user's action is to uncheck it,
we just need to make these data as "obsolete" or "invisible".

2. If user only change "Ignore file pattern",
we don't need to reindex everything,
just go through all existing data, if it matches ignore file pattern,
just remove it or make them as "obsolete".


3. If user only add some directory to watch,
we don't need to reindex all, just index these new added directories.



....

To avoid reindex everything, we need to check every preferences changes
carefully.
