I guess the easiest thing to do is simply to warn and in future compat
levels to error out with something like:
diff --git a/dh_installdocs b/dh_installdocs
index 3eefcdf..4ccd373 100755
--- a/dh_installdocs
+++ b/dh_installdocs
@@ -166,6 +166,14 @@ foreach my $package (@{$dh{DOPACKAGES}}) {
my $link_doc=($dh{LINK_DOC} && $dh{LINK_DOC} ne $package);
if ($link_doc) {
+ # TODO: does this need getpackages to be called first?
+ if (package_arch($package) ne package_arch($dh{LINK_DOC})) {
+ if (compat(9)) {
+ warning("WARNING: --link-doc between
architecture all and not all packages breaks binNMUs");
+ } else {
+ error("--link-doc not allowed between
${package} and $dh{LINK_DOC} (one is all and the other not)");
+ }
+ }
# Make sure that the parent directory exists.
if (! -d "$tmp/usr/share/doc" && ! -l "$tmp/usr/share/doc") {
doit("install","-g",0,"-o",0,"-d","$tmp/usr/share/doc");
Everything additional looks like it would have or cause quite some
problems:
- erroring out now breaks even the normal non-binNMU cases
- replacing the dependency with another version in case all->non-all
link is not possible.
- replacing the dependency with another version in case non-all->all
link gets complicated by the possibility of having different versions
for different packages. (and then results in a package nowhere having
the changelog for the binNMU, so many complications and special cases
for a not-really-solution).
- ignoring --link-doc if the packages have different arch:all-ness might
also have some nasty side-effects. And doing that only if there in an
bin-NMU case would be quite suprising and likely not that much better
than now.
- aborting with an error in case there is a broken --link-doc and there
is an binNMU currently happening has the problem of detecting that the
dependency is actually affected (due to binary packages maybe having
differing versions) and could perhaps break some binNMU that by some
other hard to forsee factors perhaps would not create a broken
package.
Of those at most erroring out in case of binNMU that is considered to
create uninstallable packages seems worth considering to me, and making
that good enough to not create new problems looks hard.
