Hello,
this is about the following Fedora change:
https://fedoraproject.org/wiki/Changes/ExcludeFromWeakAutodetect
In the tracking bugzilla, the relevant comment is:
https://bugzilla.redhat.com/show_bug.cgi?id=2013327#c4
If I understand this correctly, the current implementation is not doing what
the change described and the change owner says the feature cannot be
implemented as described.
There are several options and we should probably decide what to do before beta
freeze. Hence opening this discussion.
The change summarizes as "We would like to change a default behavior
dnf/PackageKit/microdnf to install only newly recommended packages on
upgrades." however the current impementation disbales weak depndencies in
various other scenarios, as reported by various of our packagers e.g. in
Bug 2048394 - dnf should pull weak dependencies in install transaction
Bug 2033130 - exclude_from_weak_autodetect=true effectively renders rich weak
dependencies useless
Bug 2042808 - weakdeps not working on rawhide system
The change owner proposed 4 options to move forward. I understand them as follows:
And here I am to reply to myself.
1. do nothing, keep it broken
I pretty much dislike this option. Clearly, the current behavior is not what
was approved in this change proposal. For me, it's a bad option.
2. disable this behavior by default, keep it optional, but keep it broken
This only makes sense if it's likely to get fixed and enabled again in later
Fedora release. If the plan is to disable it by default and never touch it
again, I suppose we might as well revert it entirely. I would very much to see
the change happening as it was advertised, even if we cannot make ti to Fedora 36.
For the sake of an open minded discussion, I am ignoring the fact that the
change owners themselves don't consider it doable (I think that it is doable,
but I honestly don't know if it is realistic with the current resources).
3. do not ignore already broken weak rich deps (partially reverts the change)
This sounds like a possible path forward -- it would probably still be an
improvement over the the Fedora 35 status quo, however the results might be
quite surprising for the users. If we decide to do this, I think we should
postpone to Fedora 37 neverthelss to see it in action and figure out if it's
actually a good idea or an UX nightmare.
4. change the behavior on dynamically depending on the dnf command used
(discouraged)
As stated by the change owner in the bugzilla, this is probably not a good
idea. Even when the user types `dnf install` it sometimes upgrades some already
installed packages and even if they type `dnf upgrade` it sometimes installs
some new packages.
(Go see the linked comment for details.)
Please let us know what you think is best or if there is a better solution.
