edos: only check source packages

[Andreas Barth <aba@not.so.argh.org>]

Hi,

I'm suggesting to change edos so that only the installability of
source packages is checked anymore:

diff --git a/bin/wb-edos-builddebcheck b/bin/wb-edos-builddebcheck
index 400d1e3..f04c6fc 100755
--- a/bin/wb-edos-builddebcheck
+++ b/bin/wb-edos-builddebcheck
@@ -73,9 +73,9 @@ if ( $architecture eq "" ) {
     }
 }

 open(RESULT,"python /usr/share/edos-distcheck/add-sources.py ".
-     "--prefix \"$sourceprefix\" < $packagefile $sourcesfile $architecture ".
-     "| edos-debcheck $edosoptions|");
+     "--prefix \"$sourceprefix\" < /dev/null $sourcesfile $architecture".
+     "| edos-debcheck '-base FILE' $packagefile $edosoptions|");

 $sourcestanza=0;
 $explanation="";


(If we do that, we could easily allow multiple files only for edos
purposes - this will make our life at other places easier.)


In my tests it made edos significantly faster (should be even more
relevant in practice, as we run with a smaller excerpt of the source
packages file):

(sorry, no "time" available on that machine)


This however needs this change as well:

Comments?

(What I'd really like to see is a better dependency-analysis if a
package is unavailable - but this doesn't work today as well, though
for other reasons - basically we'd need an "show also the
installability of all packages which are an failed dependency" with
edos.)

(In case we don't want to do that change, I'd still like to not pipe
the packages files through, but add them later on with -add-source.)
