      Merge branch '18193-developers-can-merge' into 'master' · 9ca633eb
      Rémy Coutable authored
      Allow developers to merge into a protected branch without having push access
      
      ## What does this MR do?
      
      Adds a "Developers can merge" checkbox to protected branches much like the "Developers can push" checkbox. When the checkbox is enabled, a developer can merge MRs into that protected branch from the Web UI and from the command-line (any push that is entirely composed of merge commits is allowed).
      
      ## Are there points in the code the reviewer needs to double check?
      
      - This MR refactors the `GitAccess` module, moving parts of it to `UserAccess` and the new `ChangeAccessCheck`.
      - This MR refactors `GitAccessSpec`, which generates a "matrix" of tests.
      - The main logic "developers can merge" should be straightforward enough.
      - The commits are fairly atomic, and the commit messages are descriptive regarding the motivations behind every change.
      
      ## Why was this MR needed?
      
      A significant portion of this feature was implemented in !4220 (thanks, @mvestergaard!) ; I'm wrapping it up.
      
      ## What are the relevant issue numbers?
      
      #18193 
      Closes #967

      ## TODO
      
      - [ ]  #18193 !4892 Add "developers can merge" as an option for protected branches
          - [x]  Review existing code
          - [x]  Fix build
          - [x]  Implementation / refactoring
              - [x]  Clean up `GitAccess`
              - [x]  Clean up `protected_branches.js.coffee`
              - [x]  Figure out authorization issue
                  - If we try to merge code into a protected branch for a user who doesn't have access to that branch, an auth check will fail
                  - We need to get around this, somehow
                  - [x]  Try detecting merge commits and allowing those
              - [x]  A push with regular commits _and_ merge commits should fail
                  - [x]  Figure out a solution
                  - [x]  Extensive tests for `MergeCommitCheck`
          - [x]  Add tests
              - [x]  Untested parts of original MR
          - [x]  Improve the checks in `/allowed`
              -  @dzaporozhets's proposal:
                  - commits in push == commits in merge request
                  - branch to push == target branch of merge request
                  - merge request has required amount of approves (ee only)
                  - merge commit in push == merge commit we created when merged via UI
                  - save merge commit sha in database and compare with `newrev`
              - my proposal
                  - /allowed finds all open merge requests with the appropriate target branch
                  - For each MR, compare the commit SHAs in the MR to the commit SHAs in the change set
                  - If we have a match, compare the diff of the matching MR to the diff of the change set
                  - If we still have a match, the merge is legit
              - [x]  Wait for replies on my proposal
              - [x]  Pick a strategy
              - [x]  Implementation
                  - [x]  Save `in_progress_merge_commit_sha`
                  - [x]  Check `in_progress_merge_commit_sha`
                  - [x]  Clear `in_progress_merge_commit_sha`
              - [x]  Test / refactor
          - [x]  Merge conflicts
          - [x]  Verify workflows
              - [x]  Developer with 'developer can merge' on:
                  - [x]  Can merge an MR from the Web UI
                  - [x]  Error message for conflicts in the Web UI
                  - [x]  Cannot merge an MR from the command line (HTTP)
                  - [x]  Cannot merge an MR from the command line (SSH)
                  - [x]  Cannot modify the branch otherwise
              - [x]  Developer with 'developer can merge' off:

              - [x]  New projects created could have have "Developers can merge" turned on automatically for the default branch
          - [x]  CHANGELOG
          - [x]  Fix build
          - [x]  Wait for [build](https://gitlab.com/gitlab-org/gitlab-ce/commit/42624e3d53754064186d4ae9048e310d1d3eed0b/builds) to pass
          - [x]  Screenshots
          - [x]  Assign to endboss
          - [x]  Respond to @dbalexandre's comments
              - [x]  Duplicated line, this is equals to line 26.
              - [x]  We aren't using any of these helpers in this migration, we can remove the include.
              - [x]  What do you think to add a default value for this column to avoid the Three-state Boolean Problem?
              - [x]  group all checks under Gitlab::Checks
              - [x]  You have a default value for developers_can_merge column, but your migration doesn't add it.
              - [x]  What do you think to rename Partially protected to anything else?
          - [x]  Fix conflicts
          - [x]  Make sure [build](https://gitlab.com/gitlab-org/gitlab-ce/commit/b1cfd42f20a78fd7f844288954e97cff32962e20/builds) passes

      - Only send a param for the currently changed checkbox.
      - Have the controller use strong parameters correctly, so that the PATCH
        works as expected.

      Refactor `Gitlab::GitAccess` · 60245bbe
      Timothy Andrew authored
      1. Don't use case statements for dispatch anymore. This leads to a lot
         of duplication, and makes the logic harder to follow.
      
      2. Remove duplicated logic.
      
          - For example, the `can_push_to_branch?` exists, but we also have a
            different way of checking the same condition within `change_access_check`.
      
          - This kind of duplication is removed, and the `can_push_to_branch?`
            method is used in both places.
      
      3. Move checks returning true/false to `UserAccess`.
      
          - All public methods in `GitAccess` now return an instance of
            `GitAccessStatus`. Previously, some methods would return
            true/false as well, which was confusing.
      
          - It makes sense for these kinds of checks to be at the level of a
            user, so the `UserAccess` class was repurposed for this. The prior
            `UserAccess.allowed?` classmethod is converted into an instance
            method.
      
          - All external uses of these checks have been migrated to use the
            `UserAccess` class
      
      4. Move the "change_access_check" into a separate class.
      
          - Create the `GitAccess::ChangeAccessCheck` class to run these
            checks, which are quite substantial.
      
          - `ChangeAccessCheck` returns an instance of `GitAccessStatus` as
            well.
      
      5. Break out the boolean logic in `ChangeAccessCheck` into `if/else`
         chains - this seems more readable.
      
      6. I can understand that this might look like overkill for !4892, but I
         think this is a good opportunity to clean it up.

      Enforce "developers can merge" during `pre-receive`. · 495db096
      Timothy Andrew authored
      1. When a merge request is being merged, save the merge commit SHA in
         the `in_progress_merge_commit_sha` database column.
      
      2. The `pre-receive` hook looks for any locked (in progress) merge
         request with `in_progress_merge_commit_sha` matching the `newrev` it
         is passed.
      
      3. If it finds a matching MR, the merge is legitimate.
      
      4. Update `git_access_spec` to test the behaviour we added here. Also
         refactored this spec a bit to make it easier to add more contexts / conditions.
