Hi!

I think the problem is known for everyone, if a user upgrades a package (without -Su), he can easily get "error while loading shared libraries".

The most perfect (but maybe overkill) solution is Florian's one: http://www.archlinux.org/pipermail/pacman-dev/2009-August/009158.html (that patch needs some work on optdepends side, but that is not so complicated.)

I mention a simpler one: Add a new switch to upgrade reversedeps too (recursively), ie. "pacman -S --reversedeps libjpeg" would upgrade all packages depend on (the local) libjpeg. This should be straightforward to implement and imho this is a bit more sophisticated than the "pacman -Syu libjpeg" request (see bugs.archlinux.org :-P).

Opinions?

Did you ever think about this more? I'm not sure I like the name of the flag, but the idea is interesting. I have the feeling more times than not it will pull in a *lot* of things (something equivalent to doing -Rsc <pkgname>) in order to be "correct".

So basically we would almost be back to -Su. Anyway there is a very simple answer to all theses problems : regular -Syu Now if the user don't do that, it suddenly all gets much more complex. The question is : do we want to support that ? - Yes : then we probably needs to go the sodepends/soprovides way, as this seems to be the only completely safe way - Yes , No, Maybe : we can add the --reversedeps option, which might help a bit, but not solve the problem - No : we keep telling user than the only supported way is to keep doing -Syu regularly
