pygorpmrustinfo 0.1.2

Unified Go-backed helpers for rpmdb, rust audit, and Go build metadata

pygorpmrustinfo

pygorpmrustinfo is a unified Python package that exposes the former rpmdb, rust audit, and Go build-info helpers through a single Go-backed extension.

Why this package exists

The older split packages each relied on their own Go runtime and native extension. That approach is fragile in Python environments because Go's c-shared mode can be unstable when multiple Go runtimes are loaded into the same process. This is the problem described in Go issue #65050: loading multiple c-shared Go libraries in one process can lead to panics, crashes, or other runtime failures.

This consolidation is meant to reduce that risk by keeping a single Go runtime in play, while also reducing memory usage compared with loading several separate native extensions.

Deprecation notice for the old scripts

The legacy entry points and package names are being deprecated. The replacement package is pygorpmrustinfo, and the compatibility scripts remain available only for transition:

• get_go_info
• get_rpm_info
• get_rust_audit
• the older standalone package names for the previous split implementations

These legacy scripts remain available for compatibility, but new work should target pygorpmrustinfo instead.

Installation

pip install pygorpmrustinfo

Usage

The package provides the same high-level functionality as the older helpers, but through one unified interface. If you are coming from the old packages, the main change is that you install and import one package instead of three separate ones.

CLI

get_go_info /path/to/go.mod
get_rpm_info /path/to/Packages
get_rust_audit /path/to/rust-binary

These scripts are preserved for compatibility, but the recommended path is to depend on pygorpmrustinfo directly.

Python API

import json
import pygorpmrustinfo

# Go build metadata
res = pygorpmrustinfo.get_go_build_info("/path/to/go.mod")
print(json.dumps(res, indent=4))

# RPM database metadata
res = pygorpmrustinfo.get_rpm_db_info("/path/to/Packages")
print(json.dumps(res, indent=4))

# Rust audit metadata
res = pygorpmrustinfo.get_rust_audit("/path/to/rust-binary")
print(json.dumps(res, indent=4))

Example: Go build info

import pygorpmrustinfo

info = pygorpmrustinfo.get_go_build_info("/path/to/go.mod")
print(info["GoVersion"])
print(info["Path"])

Example result:

{
    "GoVersion": "go1.18.4",
    "Path": "github.com/example/project",
    "Main": {
        "Path": "github.com/example/project",
        "Version": "(devel)",
        "Sum": "",
        "Replace": null
    },
    "Deps": []
}

Example: RPM database info

import pygorpmrustinfo

packages = pygorpmrustinfo.get_rpm_db_info("/path/to/Packages")
for package in packages:
    print(package.get("Name"), package.get("Version"))

Example result:

[
    {
        "Name": "bash",
        "Version": "5.1",
        "Release": "1.el9"
    }
]

Example: Rust audit info

import pygorpmrustinfo

packages = pygorpmrustinfo.get_rust_audit("/path/to/rust-binary")
for package in packages.get("packages", []):
    print(package.get("name"), package.get("version"))

Example result:

{
    "packages": [
        {
            "name": "serde",
            "version": "1.0.197",
            "kind": "build"
        }
    ]
}

The functions always return a dictionary. On error you may see a structure like:

{
    "error": "path error:/path/to/missing/file"
}

Migration from the old packages

If you previously used one of the older packages, the migration is straightforward:

• replace pyrpmdb with pygorpmrustinfo and call get_rpm_db_info(...)
• replace pyrustaudit with pygorpmrustinfo and call get_rust_audit(...)
• replace pygobuildinfo with pygorpmrustinfo and call get_go_build_info(...), get_go_mod(...), or get_go_sum(...)

For dependency declarations, update requirements, pyproject.toml, setup.cfg, or setup.py to depend on pygorpmrustinfo instead of the old package names.

Notes

• The consolidation is primarily a stability and resource-usage improvement.
• It is also a practical mitigation for the risks documented in Go issue #65050.
• If you are maintaining older automation, consider switching to the unified package now so you are not tied to the deprecated script-based workflow.
