*Before opening a new issue or submitting a new pull request, it‘s helpful to search the project - it’s likely that another user has already reported the issue you‘re facing, or it’s a known issue that we're already aware of.

How to Contribute

Pull Requests (PRs) are the main and exclusive way to contribute to the official go-git project. In order for a PR to be accepted it needs to pass a list of requirements:

  • You should be able to run the same query using git. We don't accept features that are not implemented in the official git implementation.
  • The expected behavior must match the official git implementation.
  • The actual behavior must be correctly explained with natural language and providing a minimum working example in Go that reproduces it.
  • All PRs must be written in idiomatic Go, formatted according to gofmt, and without any warnings from go lint nor go vet.
  • They should in general include tests, and those shall pass.
  • If the PR is a bug fix, it has to include a suite of unit tests for the new functionality.
  • If the PR is a new feature, it has to come with a suite of unit tests, that tests the new functionality.
  • In any case, all the PRs have to pass the personal evaluation of at least one of the maintainers of go-git.

Format of the commit message

Every commit message should describe what was changed, under which context and, if applicable, the GitHub issue it relates to:

plumbing: packp, Skip argument validations for unknown capabilities. Fixes #623

The format can be described more formally as follows:

<package>: <subpackage>, <what changed>. [Fixes #<issue-number>]
