If you encounter a bug, misfeature, or missing feature in GTK, please file a bug report on our GitLab project. You should also file issues if the documentation is out of date with the existing API, or unclear.
Don’t hesitate to file a bug report, even if you think we may know about it already, or aren’t sure of the details. Just give us as much information as you have, and if it’s already fixed or has already been discussed, we’ll add a note to that effect in the report.
The issue tracker should definitely be used for feature requests, it’s not only for bugs. We track all GTK development in GitLab, to ensure that nothing gets lost.
If you develop a bugfix or enhancement for GTK, please open a merge request in GitLab as well. You should not attach patches to an issue, or describe the fix as a comment. Merge requests allow us to build GTK with your code applied, and run the test suite, on multiple platforms and architectures, and verify that nothing breaks. They also allow us to do proper code reviews, so we can iterate over the changes.
You should follow the contribution guide for GTK, available on GitLab.
If you want to discuss your approach before or after working on it, good ways to contact the GTK developers, apart from GitLab issues, are
- the #gtk IRC channel on irc.gnome.org
- the gtk tag on the GNOME Discourse instance
You should not send patches by email, as they will inevitably get lost, or forgotten. Always open a merge request.
