Comment(by karsten):

 I just checked that metrics-db can handle cases where only the last N days
 of history are available.  But N shouldn't be 1, because the last day is
 only going to be complete shortly before it gets cut off and replaced by
 the next day.  It's also possible that metrics-db crashes and doesn't
 download the stats file for a few days or longer when I'm not around.  Can
 we set N to, say, 30?  If so, feel free to do that.

 To answer the comment: yes, metrics-db can handle removing or changing
 package names.  Removing a package would be counted as having 0 downloads
 of that package, so that'd be a safe thing to do.

 Changing package names is not so nice.  We rely on package names for
 plotting TBB (en), TBB (zh_CN), and TBB (fa).  So, if `tor-browser-
 bundle_en` would change to, say, `tbb_en`, we might have to add a rule
 saying that the two are equal.  That wouldn't make the metrics code
 prettier.  Maybe give me a heads-up before changing any package names in
 particular?

 Does that answer your question?  If so, please close the ticket or tell me
 to do so.
