Working conventions for working on GHC
GHC is a BSD-licensed open-source project, and we welcome your help in making it better. This page has pointers to information you'll need.
Especially, please read:
When you are editing GHC's source code, please follow our coding guidelines:
Our conventions and some useful tips for using darcs are here: WorkingConventions/Darcs.
The Bug Tracker
We organise our work (both bug fixing and feature requests) using the Trac bug tracker. There are links to the bug tracker in the sidebar under "View tickets" ad "Create ticket".
The following are GHC-specific policies for using the Trac bug tracking system. (See also the bug reporting guidelines.
- When a bug is fixed, but the patch or patches still need to be merged to other branches, then don't close the bug, just change its type from "bug" or "task" to "merge". Also add a list of patches to be merged, and which branch to merge to, as a comment.
- Milestones: we have milestones for each release, and three special milestones:
- An empty milestone field means the bug has not been triaged yet. We don't yet know if the ticket is a real, unique, issue. Once this has been established, the ticket will be given a milestone.
- Not GHC is for tickets that are not tied to a GHC release, because they are in libraries or other software that is not released with GHC. Bugs in the "extra libraries" typically fall into this category.
- _|_ is for tickets that have been triaged, but we don't plan to fix them for a particular release. This might be because the bug is low priority, or is simply too hard to fix right now.
- Severity: this is set by the submitter of the ticket, and indicates how important the issue is to them, i.e. is it preventing them from doing something altogether, or just a minor annoyance. The severity might be reduced if we discover a workaround.
- Priority: this field is for the GHC development team to help us prioritise what we work on. Bugs that have a high severity will tend to be prioritised higher, as will bugs that are regressions from a previous release.
- Test Case: fill in this field with the name of the test in the test suite. Typically every bug closed should have an appropriate test case added to the test suite.
