[Feature Request] "github_repository" default merge action

[jfreeland]

I would like to be able to have the default merge action for a repo created with github_repository have a default merge action that is configurable.

By default I want users to Squash and Merge but I don't want to disallow allow_merge_commit or allow_rebase_merge.

In my experience, GitHub repos default to Merge pull request (Create a merge commit), retaining the history of all previous commits, until the user clicks the green dropdown and selects Squash and merge at least once. This has me concerned that this could be a per-user setting but I would like to be able to set the default on a per-repo (per org?) basis.

Affected Resource(s)

• github_repository

Terraform Configuration Files

resource "github_repository" "example" {
  name        = "example"
  description = "My awesome codebase"

  visibility = "public"

  allow_merge_commit = true
  allow_squash_merge = true
  allow_rebase_merge = true
  default_merge_action = "squash_merge"
}

@jfreeland , I would also have loved such a feature but if I'm not mistaken, this feature doesn't exist on GitHub itself, therefore making it impossible to support this in this Terraform provider?

The GitHub feature request is here: https://github.com/community/community/discussions/20583

From my understanding, the current behavior is that the default merge action is only set on a per-user basis (last selected option for a repository is the proposed default action).

Did I miss something?

2 additional notes:

• The GitHub discussion link in your issue description seems dead?
• Just passing by when browsing the issues, I'm not maintaining anything here, do not take that as any kind of authoritative answer :smile:

It seems now implemented by GitHub: https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/configuring-pull-request-merges/configuring-commit-squashing-for-pull-requests
