pyrpmdb 0.1.34

A python package that extracts rpm package information from rpm database.

Why this and not "rpm" I needed a package that could run on environment without rpm shared libraries installable. This leverage go's portability to enable this.

Dependency note: this package is being deprecated in favor of the unified package pygorpmrustinfo. If you depend on this package in another project, update your dependency declaration (for example in requirements, pyproject.toml, setup.cfg, or setup.py) to depend on pygorpmrustinfo instead. The unified package preserves the existing functionality while avoiding the multiple-Go-runtime risk discussed in Go issue #65050 and reducing memory usage.

Example usage

from pyrpmdb import get_rpm_db_info
import json


def test_get_info(file):
    res = get_rpm_db_info(file)
    print(json.dumps(res, indent=4))


test_get_info("foo/bar")
test_get_info("/usr/bin/du")
test_get_info("test-data/centos5-plain-Packages")

The result returned is always a dict object for errors the dictionary returned contains a key; "error" like;

{
    "error": "path error:foo/bar"
}

or

{
    "error": "/usr/bin/du: could not read Go build info from /usr/bin/du: unrecognized file format"
}

on success a python list of rpm package info struct is returned of this go structure serialized

This package relies on a shared go library that leverages https://pkg.go.dev/github.com/knqyf263/go-rpmdb/pkg

So relies on this for database support.
