Dropping -devel subpackage

[Iñaki Ucar]

Hi,

Quick question not found in the docs. There's a package with a -devel
subpackage. No package depends on this -devel and upstream removes the
development files in the new release, so I just dropped the -devel
subpackage.

Now, it's improbable, but if the old -devel subpackage was installed,
then "dnf upgrade" complains, obviously:
https://bodhi.fedoraproject.org/updates/FEDORA-2019-f8c8592ad6

So the question is: should I add "Obsoletes: pkg-devel < $new_version"
to pkg's SPEC? Is this a proper use of "Obsoletes"?

Regards,

Yes. Exactly a right thing to do.

Thanks, Miro. Then, I suggest to add this particular case to the
documentation. Not sure where though, but FWIW, my first search was
"drop subpackage" and *not* the "Obsoletes" subsection.

That case should already be covered by the "replace" part of:
https://docs.fedoraproject.org/en-US/packaging-guidelines/#renaming-or-re...

That's not clear to me. I read that in the first place, and I didn't
identify this case either as a rename nor a replacement. A replacement
is like bar that obsoletes foo. But here we have foo and
foo-something, and at some point the latter is dropped (and not
provided in foo).

I'm running into just this sort of issue this with python2 modules and
Samba libraries, such as libldb, libtevent, libtalloc, and libtdb for
Samba 4.11rc1 The necessary modern visions of all of those libraries
are no longer copatible with python2. Compiling them for Fedora 30 and
RHEL 7 means that the old python2 modules are still present for
dependencies in mock, and hilarity ensues, *unless* the python3
modules are configured to "Obsolete" the python2  modules.

Originally I'd considered that the *main* package was effectively replacing 
-devel, though on second thought it's not a full replacement (ie, only 
Obsoletes without Provides).

Yes, this is correct usage of Obsoletes.
