Error: transaction test error

[Zbigniew Jędrzejewski-Szmek]

When packages want to provide the same filename and the issue cannot
be avoided, at least they should declare Conflicts with one another.
When Conflicts is declared, dnf will know about the issue from
repository metadata and refuse to install both packages and the user
can deal with that. But if they having conflicting files with
declaring Conflicts, this is only detected after packages have been
downloaded and results in a failed transaction and is generally bad UX.

Recently I was installing a bunch of packages for the the "package notes"
tests, and I was surprised how many such packages we have:

(This is not all packages in the distro, as I only requested archful packages to save some
space…)

Such conflicts lead to subpar user experience… Should we make an effort to clean this
up? Add Conflicts between those packages?
(In some cases it seems that subpackages have been renamed without Obsoleting
the previous subpackage…)

We could add a new implicit CI test to check for the conflicting files. A test
similar to fedora-ci.koji-build.installability.functional. That would inform
packagers that their new build is missing the explicit Conflicts.

>  Add Conflicts between those packages? 
Yes. It's mandated by the guidelines
<https://docs.fedoraproject.org/en-US/packaging-guidelines/Conflicts/#_imp...;.

It's not trivial to do right now, because you actually need to
download all the packages to see the issue. (Though file names are
available in the metadata files, e.g. dnf install /some/path works,
so I guess it could be done without downloading packages theoretically.)

Yeah, but is is worth the effort? I could open a bunch of bugs, but
I don't want to do this if nobody wants to look at them anyway.

icat is one of my packages.
sleuthkit has been in Fedora for 13 years now,
and "icat" has been part of the package from the very beginning, so this
conflict is on me.
(And whoever reviewed my package review request, I guess.)

I'll add the Conflicts: tag and rebuild the package later today.
A.FI.

You might be able to save yourself from downloading and installing all
packages manually, by querying repository metadata for file providers:

for package in repository:
    for file in package:
        for provider in whatprovides(file):
            if provider != package:
                print "Path {file} is provided by both {package} and
{provider}."

Though you'd probably get a bunch of false positives, for things like
shared directory ownership. Not sure if you could filter that out
somehow.

You have the tested package locally, so you know whether a file name is
a directory or not and omit the directories from testing. (There is still
a possibility of clashing a local direcotory and a remote file, but I guess
that will be close to zero.)

Of course a good test when it discovers a same-named file, before reporting an
error, it should also check whether the Conflicts has already been declared
(locally or remotely).

(And the test also needs to skip a previous version of the tested package :)
