feature request: review diffs

[PeterSewell]

It'd be really useful to be able to see the changes when reviewers update their reviews - perhaps just by appending a diff of the before and after text-rendered review to emails?

HotCRP already stores this information & has for years. Unfortunately, there are some conceptual roadblocks in showing it to users—especially to authors, who should not see most diffs (but should see some)—that have kept me from making it visible. Contributions welcome.

I was primarily thinking of the use for reviewers (and admins, assistant chairs, etc.), for whom I guess one could show all diffs, at least whenever a notification mail would have been sent? For authors, perhaps the right thing would be diffs while reviews are visible to them, and when they become visible since the last time they were (e.g. to pick up changes between author response and final reviews)? As an author, I typically dump as .txt and run diff manually for the final reviews. Peter

The API endpoint api/PAPER/reviewhistory?r=REVIEWID exposes review versions to review authors & paper managers. Probably most useful is api/PAPER/reviewhistory?r=REVIEWID&expand=1, which expands the diff patch format to full texts. This is not yet visible via the UI but it is there.
