No, I see the problem.  Thanks for the report.  I knew this was going
to bite me sooner or later, and have plans to fix it, but hadn't had
time to implement it...

This host was crawled today, and that the repodata directory isn't
up-to-date, but the crawler thinks that the updates/5/ppc/debug
directory *is* up-to-date.   But it shouldn't.

up2date   path  lastCrawled date

True updates/5/ppc 2007-05-16 07:43:17
True updates/5/ppc/debug 2007-05-16 07:43:10
False updates/5/ppc/debug/repodata 2007-05-16 07:43:02
False updates/5/ppc/repodata 2007-05-16 07:43:22

The problem is, the database doesn't track every single file in a
directory full of RPMs or HTML files.  That would have exploded the
size of the database. So, I only look at 10 files in such directories
(and all files in all other directories).  It's supposed to be "the
ten most recent files", but that part of the logic is what's broken.
It uses the first ten as reported by the dict, which isn't right.

I'll have to fix that to solve this.  It's just a matter of adding
rsync directory list parsing into the update-master-directory-list
program, shouldn't be hard, just needs a little time and a little
testing...

Thanks,
Matt
