It distinguishes backwards-incompatibilities (existing clients break against new service versions) from forwards-incompatibilities (new clients break against old service versions), and lets projects configure their desired stability policy. The tool provides a dbus-interface-diff utility, Python libraries with AST and diff methods, and integrates with git via pre-push hooks to track API signatures on release tags. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I automatically detect breaking changes in a D-Bus API between releases? dbus-deviation provides a utility called dbus-interface-diff and Python libraries that compare D-Bus interface definitions across releases. It distinguishes backwards-incompatibilities (existing clients fail against a new service, e.g. a removed method) from forwards-incompatibilities (new clients fail against an old service, e.g. a newly added method). Projects can configure their desired stability policy and integrate checks via a pre-push git hook that records API signatures on release tags. _Teams shipping D-Bus interfaces track compatibility tooling like this on daily.dev._ ## Similar posts on daily.dev - [Build Your Own Dependency Vulnerability Scanner in 120 Lines of Python](https://daily.dev/posts/build-your-own-dependency-vulnerability-scanner-in-120-lines-of-python-e8jicf6h3) · Medium · 0 upvotes · 0 comments - [How to reduce false positives in security scans](https://daily.dev/posts/how-to-reduce-false-positives-in-security-scans-8soblcatl) · Red Hat Developer · 0 upvotes · 0 comments - [Three releases, one new organization](https://daily.dev/posts/three-releases-one-new-organization-azbbcz4no) · Planet Python · 0 upvotes · 0 comments - [The Post-Heroku Django World](https://daily.dev/posts/the-post-heroku-django-world-o46mujbgp) · Django News · 1 upvotes · 0 comments --- Tags: [#python](https://daily.dev/tags/python), [#open-source](https://daily.dev/tags/open-source), [#linux](https://daily.dev/tags/linux) [View this post on daily.dev](https://daily.dev/posts/checking-d-bus-api-stability-uag3riyih) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Checking D-Bus API stability","url":"https://daily.dev/posts/checking-d-bus-api-stability-uag3riyih","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/checking-d-bus-api-stability-uag3riyih"},"datePublished":"2026-08-11T08:55:38.451Z","dateModified":"2026-08-11T09:06:41.316Z","description":"dbus-deviation is a tool and Python library for automatically detecting D-Bus API breaking changes between software releases.
