Actually, my patch is not acceptable. I totally overlooked a really crap
fact : there are a HUGE number of packages without the FILENAME field in
the databases (not community, but all others)
find /var/lib/pacman/sync/ -name desc | wc -l
grep -r FILENAME /var/lib/pacman/sync/ | wc -l
900 packages without it. Let's look at one of these :
In that desc file, we have NAME and VERSION, but not ARCH, so the
filename generated is :
And actually, that's the real filename which exists on the mirrors.
So we have two kind of entries : entries without filenames (their real
filenames don't have the -arch suffix) and entries with filenames (which
have the -arch suffix).
So the current filename fallback can't be removed at all. It actually
works for the entries without filenames, and there are a lot of them
The only correct way for dealing with this is exactly what your patch
does. First load the desc level, then use the filename field if it
exists. Otherwise fallback.
