Hi, This is somewhat related to the mail I just sent.

Evolution doesn't log or send out any sort of notification when the status of mails change, and so we have to manually walk its data whenever someone on disk changes and update our own internal state accordingly. The inotify events generated by Evoltuion as it writes out its IMAP summary to disk is how we notice these changes, but it doesn't necessarily mean that the data itself has changed. So every time these files change, we have to walk the file. > I am not sure if I'm actually saying this is a bug.

Varadhan and I have come up with a solution that'll go into Evolution such that the overhead of doing this will be pretty greatly reduced. We're not going to be able to avoid looking at the files, but we should be able to do a lot of the operations much faster. I've also fixed a bug in CVS recently that was causing Beagle to get into a tighter CPU loop when walking across these files that subverted our scheduler, so hopefully the impact won't be as noticeable now. Finally, there has been some talk about maybe suspending indexing while on battery power -- and there are some bugs open about that -- but there aren't any concrete plans about that right now. > Or could it be smarter and figure out somehow which summary files it > really needs to update but without polling all of them? (but then it > would need to somehow talk with Evolution, right?) We might also be able to do this, but right now Evolution isn't sending notifications about these unless you use a fairly experimental plugin. > Am I making at least one valid point? :-) Yes, well said. :) Thanks, Joe _______________________________________________ Dashboard-hackers mailing list Dashboard-hackers@gnome.org http://mail.gnome.org/mailman/listinfo/dashboard-hackers
