Description

The logic to request a diff fragment with a base FileDiff ID was never

actually implemented. The RB.DiffReviewable model generated a URL with

an invalid query string and, even if it were valid, the

DiffFragmentView did not know how to ask for a single FileDiff with a

base FileDiff.
The RB.DiffReviewable model now generates a correct URL and the

DiffFragmentView can parse this into a call into get_diff_files with

the appropriate parameters.
Additionally, the base FileDiff determination in get_diff_files was

incorrect: it returned an ancestor that was too old. This has been

corrected to return the least recent FileDiff from after the specified

base commit.

Testing Done

Ran unit tests.

Do we have proper checks and test coverage here? It's crucial that nobody can get to other people's diffs through this.

brennie Oct. 24, 2018, 10:20 a.m.

We do have proper checks in place (line 619):

        elif base_filediff_id:
            interfilediff = None
            base_filediff = get_object_or_404(FileDiff, pk=base_filediff_id,
                                              diffset=diffset)


but I will add some test coverage.

Let's pull the index out. This is a lengthy expression to put into a template literal. Debugging is easier if we keep the literals very small.
