I am using Calibre to feed my iPhone (and soon, Kindle) with downloaded news when on the road. Since Calibre doesn't let me keep only the last X issues of each news source (the X is global, not source-specific), I wrote a little Python script to purge older news items. And since I was in there, I added epub-to-mobi conversion for when I get my Kindle.

Trouble is, although my script works, and it uses the calibredb binary to update Calibre for both removal of books and addition of new formats, neither the GUI nor the web front-end show the updates: the GUI will pick up new formats but not remove any books, and the Web does neither.

Any ideas on how to force an update without restarting the whole app?
