Perhaps it's not obvious, but the idea here is that RPM will "sense"
what the name of the subpackage it depends on is, and generate the
correct strict dependency automatically.
For example, foo, foo-libs, libfoobaz, and foo-devel exist, built from foo.spec.
foo-devel requires libfoobaz.so.1 (provided by libfoobaz) and
libfoo.so.0 (provided by foo-libs).
Currently, rpm generates the "libfoobaz.so.1()(64bit)" and
"libfoo.so.0()(64bit)" dependencies and leaves the rest to you. This
will change the behavior so that when it identifies that a subpackage
produced from the spec contains that dependency, it'll be replaced
with a strictly versioned dep on the subpackage. So instead of
"libfoo.so.0()(64bit)", it'll be "foo-libs%{?_isa} =
%{version}-%{release}". And the "libfoobaz.so.1()(64bit)" dependency
would be replaced with "libfoobaz%{?_isa} = %{version}-%{release}".
I'm not saying it's right or wrong (but probably it's more
"right"):
However this does change the actual semantics, I think. I mean,
previously "libfoobaz.so.1()(64bit)" might have been satisfied by an
older -libs package, or by another package which happens to provide
libfoobaz.so.1. I wonder if anything relies on that?
Rich.
If there's no requires that matches with a provides in another
subpackage that's built from the spec, rpm would not do anything, and
it'll be exactly as it is now.
This is merely about optimizing requires across subpackages from the
same source package.
