Fix options override order in RB.apiCall.
Review Request #12463 — Created July 11, 2022 and submitted
RB.apiCallhas had a long-existing bug where built-in callbacks could
get shadowed by options arguments. The intent of the implementation is
that the built-in
completecallbacks always run, and will
then call any ones which are passed in by the caller. Unfortunately, the
order of arguments passed to
$.extend()prevented this from working as
intended. For existing versions of Review Board, the only noticeable
effect was the error shadows within the OAuth UI, which were highly
unlikely to occur. With the JS refactoring that happened for 5.0, we
added a complete callback for diff fragments, which override the
built-in one, causing the activity indicator to never disappear.
To fix this, I've rearranged the
$.extend()call a bit in order to
ensure that the built-in callbacks always run first. Because the
built-in error callback has its own display mechanism, I've just removed
the error display from the OAuth code.
- Ran js-tests.
- Verified that the diff fragment loader now correctly hid the activity
- Checked that the OAuth error handlers worked as expected.
- Audited all callsites to
RB.apiCallto ensure that there wouldn't be
