fedrq - new repoquerying tool
Hi Fedorians,
I've been working on a repoquerying tool called fedrq [1] that I'd like
to share with you. Here's the elevator pitch: fedrq provides a friendly
interface to query the Fedora repositories. It makes it really easy to
query across Fedora and EPEL branches. It uses the dnf Python bindings
(libdnf5 backend is almost done) and doesn't shell out to dnf repoquery.
Amongst other things, fedrq allows querying for reverse dependencies,
packages that contain a certain Provide or file, subpackages of an SRPM,
and general package metadata. My favorite features are the easy branch
switching, `fedrq subpkgs` (there's no real equivalent in dnf
repoquery), and the ability to dump package metadata as JSON. The many
threads about how to properly query for dependencies when doing SO name
bump rebuilds and my own frustrations with dnf repoquery inspired this
tool.
You can install fedrq from PyPI or from gotmax23/fedrq [2] on Copr. The
EXAMPLES section of fedrq(1) [3] provides a good intro and demonstration
of fedrq's functionality. The tool is very much a WIP and any feedback
is appreciated.
For reverse dependency rebuilds, you probably want the following
command:
```
$ fedrq whatrequires -X -F source $(fedrq subpkgs SRCNAME) # equivalent
$ fedrq subpkgs SRCNAME | fedrq whatrequires -X -i -F source # equivalent
```
This accounts for any package that depends on any subpackage/binary RPM
produced by SRCNAME at buildtime and/or runtime, and spits out the names
of the source packages that need to be rebuilt. For simple packages that
output only one RPM, `fedrq whatrequires -F source PKGNAME` is
sufficient.
