Bug#19467: devscripts: uscan fails to find latest version
Package: devscripts
Version: 1.5
vanzandt:/usr/local/src$ uscan mirrordir-0.9.10/
-- Scanning for watchfiles in mirrordir-0.9.10/
-- Found watchfile in mirrordir-0.9.10
Version on FTP Site is 0.9.9. Package is 0.9.100
^ this is wrong
=> mirrordir-0.9.9.tar.gz already in package directory
-- Scan finished
Actually, version 0.9.11 was available:
mirrordir-0.9.10.tar.gz
mirrordir-0.9.11.tar.gz
mirrordir-0.9.2.tar.gz
mirrordir-0.9.3.tar.gz
mirrordir-0.9.4.tar.gz
mirrordir-0.9.5.tar.gz
mirrordir-0.9.6.tar.gz
mirrordir-0.9.7.tar.gz
mirrordir-0.9.8.tar.gz
mirrordir-0.9.9.tar.gz
The problem is a string sort. I suggest this patch, which assumes a
version number of the form X.Y.Z, and does a numerical comparison of
corresponding fields:

It still fails when the first component goes from 9 to 10.
