doxbox-staging package conflict

[Vitaly Zaitsev]

Hello all.

doxbox-staging is trying to overwrite the regular dosbox package:

Installing:
  dosbox-staging            x86_64            0.76.0-2.fc34 
  fedora            1.4 M
      replacing  dosbox.x86_64 0.74.3-7.fc34

From its SPEC[1]:

# This package is a drop-in replacement for dosbox
Provides:  dosbox = %{version}-%{release}
Obsoletes: dosbox < 0.74.4

Is this Okay? These packages has different maintainers. According to the 
Fedora packaging guidelines, one package cannot introduce conflicts with 
another.

This is intentional, regular dosbox is more-or-less (*) unmaintained upstream so we have decided to switch to dosbox-staging, also see the Package Review for dosbox staging:
https://bugzilla.redhat.com/show_bug.cgi?id=1884608

As such dosbox-staging is intended as a replacement for the regular dosbox (and it is fully compatible with the regular dosbox). This was coordinated with the dosbox owner, but we have forgotten to actually retire dosbox, sorry about that. I'll retire dosbox in rawhide right away.

Regards,

Hans

*) They have not done a release in many years, nor has any meaningful feature development are maintenance like moving to SDL2 happened.

I think it is great that Fedora now has dosbox-staging and arrow keys 
work again. Many games were quite annoying to play without them. And 
there are other improvements as well.

But the complaint I have about this process is that, if you use the 
default dosbox-staging config, quite many games that actually ran with 
dosbox crash on dosbox-staging startup. That problem should be patched 
around somehow before dosbox can go. See Bugzilla discussion [1].

As an aside, I'm slightly confused why dosbox wasn't just replaced
with dosbox-staging with the same packaging...

Different upstreams (different teams, etc).

Right, the original dosbox project is still somewhat alive, so the purpose
of having a dosbox-staging package instead of just putting the tarbal from
dosbox-staging into the dosbox package is to make it clear that Fedora is
packaging dosbox-staging and not the original dosbox.

Good news, the exec-heap permission issue should be fixed by this upstream commit:

https://github.com/dosbox-staging/dosbox-staging/commit/649a428dc368cc03b1cf...

Unfortunately this does not apply at all to 0.76.0 though, so we cannot just cherry-pick the fix and add it to the Fedora packages.

One option would be to switch to a git snapshot for now.

Lets discuss this further in:

https://bugzilla.redhat.com/show_bug.cgi?id=1960865

Which seems to be the bug where this is actually being tracked.

Hans
