Based on fedora devel [1] list, there's neat dnf's functionality: $ dnf repoquery --whatrequires libarchive --alldeps --installed But it would be nice to have something like '--whatrequires --alldeps' option directly in RPM (unless that's already there). [1] https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/XI2JCLX5CIFWCJNKAV23KRESCQGT54RO/
$ rpm -q --provides libarchive | awk '{print $1}' | xargs rpm -q --whatrequires
Yep, something like that could solve RPM directly.
This is technically a dupe of bug 142651 which is a dupe of bug 84176 which easily predates repoquery but I never much cared for the suggested --whatneeds name. What a software *needs* is users, what it *requires* to function is an entirely different question, and whether the requirements are depsolved or not is yet another question. repoquery (the yum-based one) originally mimiced rpm but then sanity prevailed: > commit bc3d026acd1c8f332d024bf9a9918da6451c8c07 > Author: Ville Skyttä <ville.skytta> > Date: Tue Feb 9 21:35:15 2010 +0200 > > Make --alldeps the default in repoquery. > > --alldeps is what people really almost always want, but fail to > specify for some reason. --exactdeps can be used to get the previous > default of exact matching. Not sure what dnf repoquery does but from the sound of this, it's defaulting to the stupid rpm behavior which almost nobody wants. So what rpm really needs is a switch to enable/disable depsolve on all those --whatrequires/recommends etc options, which is what this bug describes in clear and conscise matter. So to keep in tradition of closing the older bug as dupe ;) I'm keeping this one. There's also another way to get rpms opinion: $ rpm -e --test rpm-libs 2>&1 | awk '/^\t/ {print $NF}' That is subtly different from the --provides/--whatrequires combination in comment #1 as --test considers the %pre/%post dependency differences (ie its a real dependency check), --provides/--whatrequires does not.

Since DNF 2.0, it's not true anymore.

Good. So once again history repeats itself :)
Moving the RFE to upstream.
