Auto-fix duplicate reviews.
Review Request #898 — Created June 17, 2009 and submitted
Auto-fix duplicate reviews. Under times of heavy server load, it's possible to get duplicate draft Review objects in the database. This is harder with RC3, but still possible. All it requires is that the databsae is under load and two comments or reviews are created within a span of time on the server by the same person on the same review request. This had to be manually fixed in the database before, and caused frustration for those who hit it. This problem is pretty specific to draft reviews. This change now introduces a central function to call to get the draft review for a review request, and if more than one review is found, it will consolidate them into a single review and return it.
This consolidation code has been pretty well tested on an actual live server with many duplicate reviews. There's also unit tests to make sure that this functionality continues to work.
