1. Instantiate `ProtectedBranchesAccessSelect` from `dispatcher`
2. Use `can?(user, ...)` instead of `user.can?(...)`
3. Add `DOWNTIME` notes to all migrations added in !5081.
4. Add an explicit `down` method for migrations removing the
`developers_can_push` and `developers_can_merge` columns, ensuring that
the columns created (on rollback) have the appropriate defaults.
5. Remove duplicate CHANGELOG entries.
6. Blank lines after guard clauses.
1. It makes sense to reuse these constants since we had them duplicated
in the previous enum implementation. This also simplifies our
`check_access` implementation, because we can use
`project.team.max_member_access` directly.
2. Use `accepts_nested_attributes_for` to create push/merge access
levels. This was a bit fiddly to set up, but this simplifies our code
by quite a large amount. We can even get rid of
`ProtectedBranches::BaseService`.
3. Move API handling back into the API (previously in
`ProtectedBranches::BaseService#translate_api_params`.
4. The protected branch services now return a `ProtectedBranch` rather
than `true/false`.
5. Run `load_protected_branches` on-demand in the `create` action, to
prevent it being called unneccessarily.
6. "Masters" is pre-selected as the default option for "Allowed to Push"
and "Allowed to Merge".
7. These changes were based on a review from @rymai in !5081.
1. This is a third line of defence (first in the view, second in the
controller).
2. Duplicate the `API::Helpers.to_boolean` method in `BaseService`. The
other alternative is to `include API::Helpers`, but this brings with it
a number of other methods that might cause conflicts.
3. Return a 403 if authorization fails.
1. The new data model moves from `developers_can_{push,merge}` to
`allowed_to_{push,merge}`.
2. The API interface has not been changed. It still accepts
`developers_can_push` and `developers_can_merge` as options. These
attributes are inferred from the new data model.
3. Modify the protected branch create/update services to translate from
the API interface to our current data model.
1. Remove `master_or_greater?` and `developer_or_greater?` in favor of
`max_member_access`, which is a lot nicer.
2. Remove a number of instances of `include Gitlab::Database::MigrationHelpers`
in migrations that don't need this module. Also remove comments where
not necessary.
3. Remove duplicate entry in CHANGELOG.
4. Move `ProtectedBranchAccessSelect` from Coffeescript to ES6.
5. Split the `set_access_levels!` method in two - one each for `merge` and
`push` access levels.
1. Move to dropdowns instead of checkboxes. One each for "Allowed to
Push" and "Allowed to Merge"
2. Refactor the `ProtectedBranches` coffeescript class into
`ProtectedBranchesAccessSelect`.
3. Modify the backend to accept the new parameters.
1. Improve error handling while creating protected branches.
2. Modify coffeescript code so that the "Developers can *" checkboxes
send a '1' or '0' even when using AJAX. This lets us keep the backend
code simpler.
3. Use services for both creating and updating protected branches.
