list or generate patches with `git format-patch` and send them to the
[rails-dev](https://lists.openstreetmap.org/listinfo/rails-dev) list. If you are creating a larger pull request, then please help the maintainers
with making the reviews as straightforward as possible:
* The smaller the PR, the easier it is to review. In particular if a PR is too
large to review in one sitting, or if changes are requested, then the
maintainer needs to repeatedly re-read code that has already been considered.
* The commit history is important. This is a large codebase, developed over many
years by many developers. We frequently need to read the commit history (e.g.
using `git blame`) to figure out what is going on. So small, understandable,
and relevant commits are important for other developers looking back at your
work in future.
If you are creating a large pull request then please:
* Consider splitting your pull request into multiple PRs. If part of your work
can be considered standalone, or is a foundation for the rest of your work,
please submit it separately first.
* Avoid including "fixup" commits. If you have added a fixup commit (for example
to fix a rubocop warning, or because you changed your own new code) please
combine the fixup commit into the commit that introduced the problem.
`git rebase -i` is very useful for this.
* Avoid including "merge" commits. If your PR can no longer be merged cleanly
(for example, an unrelated change to Gemfile.lock on master now conflicts with
your PR) then please rebase your PR onto the latest master. This allows you to
fix the conflicts, while keeping the PR a straightforward list of commits. If
there are no conflicts, then there is no need to rebase anything.
