We created a website, you enter a commit and it shows you the reviews: http://cesel.encs.concordia.ca/process_request.php?repo=git The site will either display the message id for the review or redirect you the mailing list archive.

The name/date match works for most cases even in slightly > tweaked forms. In our technique, we take each email patch, eliminate white space and hash each line. We then compare the lines with those in commits to the same files. The commit that changes the same files and has the largest number of matching lines is considered to be the reviewed commit. We compared Junio's (author, authordate) and our technique on a manually created benchmark of 30 messages from the linux, postgres, and git mailing lists. We found that Junio's simple technique performed equally well to our more complicated technique (see results at end of email). On Tue, Feb 18, 2014 at 12:28 AM, Jeff King <p...@peff.net> wrote: > 2.

We wanted a way to store each review as its own blob, so we put the reviews on a detached 'review' branch and then wrote some simple scripts to access and display these reviews on the command line (\eg git reviewed --show <commit_hash>). However, given the previous discussion on this list (http://git.661346.n2.nabble.com/RFC-RFH-Fun-things-with-git-notes-or-patch-tracking-backwards-td2297330.html), we agree that just putting the msg_id as a note is probably more useful. One additional problem we ran into when storing all the reviews, is for something like Linux, the reviews took up a massive amount of storage. > It would be interesting to apply some kind of clustering algorithm that > automatically determines the messages related to a commit, including > both the patch but also any discussion leading up to it.

I can reach for the stars. :) It would be interesting to be able to tie in other discussion, perhaps related bugs. A future project.
