virtual providers don't apply to runtime dependencies?

virtual providers don't apply to runtime dependencies?

[Robert P. J. Day]

  in this section:

https://docs.yoctoproject.org/dev-manual/common-tasks.html#using-virtual-providers

one reads the note:

"Virtual providers only apply to build time dependencies specified
with PROVIDES and DEPENDS. They do not apply to runtime dependencies
specified with RPROVIDES and RDEPENDS."

  except in current oe-core, there seem to be a couple examples of
that:

meta/recipes-core/systemd/systemd-bootconf_1.00.bb:RPROVIDES:${PN} +=
"virtual/systemd-bootconf"

meta/recipes-bsp/grub/grub-bootconf_1.00.bb:RPROVIDES:${PN} +=
"virtual/grub-bootconf"

  am i misreadimg something?

I think the point was that PREFFERED_PROVIDER and virtual providers only apply
for the selection of recipes to build.

You still can have packages named the same (virtual rprovider or not),
and I think bitbake will take the one from the PREFFERED_PROVIDER and if
it cannot find it in that recipe, then it's going to build another one
that might have that package.

I had that issue with openssl-conf (or openssl10-conf, don't remember)
package for example.

I don't see right now how to rephrase the paragraph (provided what I'm
saying is correct :) ).

No, the above lines are incorrect and should be fixed. A bug or something to
track that would be good.

Oops, I now understand that I misunderstood Richard's point. The lines
in the recipes are wrong, not the documentation text.

So bug https://bugzilla.yoctoproject.org/show_bug.cgi?id=14530 is not a
documentation bug, but an OE core one. I'll fix this.

Thanks for your patience with us mere mortals, Richard ;-)
Michael.

Don't worry, it was a nice opportunity at least for me to clarify some
notions and it will allow to improve recipes in OE core.

Thanks for everything!
Michael.
