Hi,
I was thinking about this for a while and I got the impression that this
is something I don't know the answer for. The question is a bit harder
to formulate simply, so let put it in examples:
a) A need packaging guideline is about to be discussed. A member of FPC
wants to know how many packages would be affected so they run a quick
grep query over all the rawhide specfiles at [0].
b) A CVE is found in a web framework, so bugz are filled for the
"framewrok" package to be fixed in Fedora 27, because newer Fedoras have
newer version of the framework where the CVE is not applicable.
c) A new version of interpreted language lands in rawhide. All packages
depending on the interpeter need mass rebuild in a side tag.
d) A packager decides to retire a library and they check nothing in
Fedora requires it.
I wonder how are such situations meant to be handled with modules?
Do we build modules for rawhide? If so, should Fedora changes (such as,
but not limited to, "the Changes") somehow handle all the modules, or is
it the modular maintainer responsibility to make sure their module works
on the next Fedora version?
For the above examples, here are some more specific situations with more
specific questions:
a) I was planning to propose a more strict "No more automagic Python
bytecompilation" [1] change for Fedora 30 where we would query all
packages that depend on the old behavior and mass add "%global
_python_bytecompile_extra 1" to all of them, so we could switch the
default to be 0. Normally, we would do it in Rawhide only. But how do I
handle modules? How do I find out what modular packages rely on the old
behavior?
b) A CVE was filled for Django [2]. How does the security team
responsible for tracking CVEs figure out we have Django 1.6 in modular
Fedora? How is a bugzilla filled against a modular package anyway?
c) When we recently mass rebuilt Python 3 packages for Python 3.7,
should we go and seek for modules that use Python 3 (how do I do that?)
and rebuild the packages in the modules (or even the modules?)?
d) (this example is not real (yet)) We decide to retire (remove)
python2-sphinx because upstream Sphinx no longer supports Python 2. We
make sure that nothing in Fedora requires or buildrequires it, as all
Fedora's Python packages use python3-sphinx or no Sphinx at all. However
there is a Django 1.6 module where python-django uses python2-sphinx to
build the docs, while python2-sphinx is not part of the module itself.
How do we find out about this and is it our reprehensibility to keep it
in rawhide or add it to the module?
Sorry if those things are obvious, yet I don't know the answers. There
might be even more examples where traditionally we would only think
rawhide, but now with modules the problem seems more complex.
