# rmdepcheck

rmdepcheck is an RPM dependency check tool based on a repository metadata modification approach.
It works by comparing a checked repository to one or more base repositories. First, checks are run
on the base repositories as-is. Next, modified copies of the base repositories' metadata is
created, with all packages from the same source RPM(s) as the package(s) in the checked
repositories removed. Finally, checks are run again on the modified base repositories, with the
checked repositories available to the dependency solver. The results of the two runs are compared.
New failures should indicate problems introduced by the checked repositories. Also, some relevant
checks are run on the checked repositories with reference to the modified base repositories.

Optionally, additional base repositories can be specified which will not be modified, and
additional new repositories can be specified which will not be checked directly. The former is
intended for testing scenarios like stable Fedora releases, which have a frozen release repository
which is never modified, and an updates repository which is updated. The latter is intended for
multilib scenarios; it may be desirable to use such an additional repository for packages for
the multilib arch(es), if e.g. installability of these should not be tested directly.

## Requirements

rmdepcheck has no run-time Python dependencies outside the standard library. However, it requires
several command-line utilities:

* dnf
* zstd
* curl

It checks for these, and will exit early with an error if any of them is not found. rmdepcheck
is written primarily for Red Hat-family distributions, but should in theory be usable anywhere
these utilities can be installed (and forward slashes act as directory separators).

## Installation

Installation of rmdepcheck is entirely optional, it can be run just as well directly from the
repository. Otherwise, rmdepcheck uses setuptools for installation and is PEP 518-compliant. You
can build and install with e.g. the `build` module and `pip`. rmdepcheck can also be installed
directly from PyPI with pip and other tools.

## Usage

Simple usage looks like this:
```
rmdepcheck https://a.base.repo.example/repo,file:///another/baserepo file:///the/testedrepo
```

The to-be-modified base repositories are specified as a comma-separated list. Repositories are
always specified as URLs. Only file:// , http:// and https:// URLs are accepted.

For more complex usage, see `rmdepcheck --help`.

Note rmdepcheck is really only intended for use as a script, not as an importable library. If you
want to use it as a library go ahead, but this isn't a supported use case and bugs in it may not
be addressed.
