!581 has a lot of changes that would cause merge conflicts if not
properly backported to CE. This commit/MR serves as a better
foundation for gitlab-org/gitlab-ee!581.
= Changes =
1. Move from `has_one {merge,push}_access_level` to `has_many`, with the
`length` of the association limited to `1`. This is _effectively_ a
`has_one` association, but should cause less conflicts with EE, which
is set to `has_many`. This has a number of related changes in the
views, specs, and factories.
2. Make `gon` variable loading more consistent (with EE!581) in the
`ProtectedBranchesController`. Also use `::` to prefix the
`ProtectedBranches` services, because this is required in EE.
3. Extract a `ProtectedBranchAccess` concern from the two access level
models. This concern only has a single `humanize` method here, but
will have more methods in EE.
4. Add `form_errors` to the protected branches creation form. This is
not strictly required for EE compatibility, but was an oversight
nonetheless.
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. The model now contains this humanization data, which is the once
source of truth.
2. Previously, this was being listed out in the dropdown component as well.
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.
Destruction is taken care of with `dependent: :destroy`
1. Modify the component to support a callback for every key press in the
filter. We need this so we can update the "Create: <branch_name"
label.
2. Modify the component to use `$(<selector>).first().click()` instead
of `$(selector)[0].click()`, because the latter is non-standard, and
doesn't work in PhantomJS.
1. Allow entering any branch name for a protected branch.
- Either pick from a list of options, or enter it manually
- You can enter wildcards.
2. Display branches matching a protected branch.
- Add a `ProtectedBranches#show` page that displays the branches
matching the given protected branch, or a message if there are no
matches.
- On the `index` page, display the last commit for an exact match,
or the number of matching branches for a wildcard match.
- Add an `iid` column to `protected_branches` - this is what we use for
the `show` page URL.
- On the off chance that this feature is unnecessary, this commit
encapsulates it neatly, so it can be removed without affecting
anything else.
3. Remove the "Last Commit" column from the list of protected branches.
- There's no way to pull these for wildcard protected branches, so it's
best left for the `show` page.
- Rename the `@branches` instance variable to `@protected_branches`
- Minor styling changes with the "Unprotect" button - floated right
like the "Revoke" button for personal access tokens
4. Paginate the list of protected branches.
5. Move the instructions to the left side of the page.
