[Help] Scanning ftp directory with uscan does not seem to work (dcmtk)

[Andreas Tille]

Hello,

I noticed that the watch file for dcmtk

version=3
ftp://dicom.offis.de/pub/dicom/offis/software/dcmtk/dcmtk([\d\.]+)/dcmtk-(.*)\.tar.gz

does not work properly.

$ uscan --verbose
-- Scanning for watchfiles in .
-- Found watchfile in ./debian
-- In debian/watch, processing watchfile line:
   
ftp://dicom.offis.de/pub/dicom/offis/software/dcmtk/dcmtk([\d\.]+)/dcmtk-(.*)\.tar.gz
uscan warning: In debian/watch no matching dirs for pattern
  
ftp://dicom.offis.deftp://dicom.offis.de/pub/dicom/offis/software/dcmtk/dcmtk([\d\.]+)
-- Scan finished

My guess is that uscan is unable to scan an ftp directory because several 
attempts
I tried end in failures:

ftp://dicom.offis.de/pub/dicom/offis/software/dcmtk/dcmtk(.*) 
dcmtk-([\d.]+)\.tar\.gz

$ uscan --verbose

I tried my luck with uversionmangle expressions to get rid of this problem but 
failed after
several tries.  I also tried:

ftp://dicom.offis.de/pub/dicom/offis/software/dcmtk/dcmtk([^/]*) 
dcmtk-([\d.]+)\.tar\.gz
$ uscan --verbose
-- Scanning for watchfiles in .
-- Found watchfile in ./debian
-- In debian/watch, processing watchfile line:
   ftp://dicom.offis.de/pub/dicom/offis/software/dcmtk/dcmtk([^/]*) 
dcmtk-([\d.]+)\.tar\.gz
uscan warning: In watchfile debian/watch, reading FTP directory
  ftp://dicom.offis.de/pub/dicom/offis/software/dcmtk/dcmtk([^/]*) failed: 404 
Not Found
-- Scan finished


Is there any solution for this problem I might have overlooked or is it just
a bug in uscan which should be reported.

Kind regards

         Andreas.
