fedrq

A tool for querying the Fedora and EPEL repositories

fedrq makes it easy to query any branch of Fedora or EPEL. It uses the dnf Python bindings and does not shell out to dnf repoquery. It allows querying for reverse dependencies, packages that contain a certain Provide or file, subpackages of an SRPM, and package metadata.

The tool doesn't seek to replace every feature of dnf repoquery. It provides a more user friendly interface than dnf repoquery for certain common tasks.

Installation

fedrq has a Copr repository at gotmax23/fedrq that contains released versions. Development snapshots are available at gotmax23/fedrq-dev. The RPM specfile is located in the repository root.

fedrq is also published to PyPI so you can pip install fedrq.

When installing the package with pip, some additional system packages are needed.

The following additional system package is required for the dnf backend:

• python3-dnf (dnf is currently the default Fedora package manager, so this should already be installed)

The following additional system packages are required for the libdnf5 backend:

• python3-libdnf5

The following additional system packages are always required:

• python3-rpm

fedrq defaults to the dnf backend, but fedrq falls back to the libdnf5 backend if the former's dependencies aren't installed. Users can explicitly choose a backend with the --backend CLI option or globally in the fedrq config file.

Note that fedrq can only be installed for the system python interpreter. fedrq cannot be installed in a venv unless it has --system-site-packages, as it needs to find the aforementioned system bindings.

fedrq check-config --dump requires tomli-w. The RPM package weakly depends on python3-tomli-w.

Container images

fedrq now provides container images.

• quay.io/gotmax23/fedrq:latest is built with registry.fedoraproject.org/fedora:latest.
• quay.io/gotmax23/fedrq:ubi9 is built with the ubi9 image. It includes a builtin rhel9 repository configuration that can be used to query the actual RHEL repositories when run on a system registered with subscription-manager.

Both of these images use the latest fedrq RPM packages from the gotmax23/fedrq Copr repository.

$ podman run --rm -v ~/.cache/fedrq:/fedrq-cache/fedrq:z quay.io/gotmax23/fedrq \

Versioning

This project is in beta and its versioning scheme follows semver.

See NEWS.md.

Python API

The fedrq.config module and the fedrq.backend package are public API. Everything under fedrq.cli is internal. fedrq is primarily a CLI tool and its API only abstracts the specific dnf/libdnf5 functionality that the CLI uses. The API's main purpose is "repoquerying", but you can use the fedrq functionality you'd like and then access the underlying dnf Base object to preform other tasks if needed.

See the API Summary on the docsite for more information. See api-examples for some example code. As always, direct any feedback, questions, or issues to the mailing list (see Contributing).

Documentation

See fedrq's documentation site for rendered manpages, changelogs, and Python API documentation.

Contributing

Development, issue reporting, and project discussion happen on the mailing list (~gotmax23/fedrq@lists.sr.ht).
