I would like to replicate all information associated with a Differential review such as comments etc in a git repository using [[ https://www.kernel.org/pub/software/scm/git/docs/git-notes.html | git-notes ]]. This would make the repository self-contained and all information related to reviews would be included and available offline. Gerrit stores review information in git-notes, see [[ http://blog.adamspiers.org/2013/10/02/more-uses-for-git-notes/ | here ]] and [[ https://gerrit-review.googlesource.com/#/admin/projects/plugins/reviewnotes | here ]].
By means of an event listener for the TYPE_LAND_WILLPUSHREVISION git notes could be generated and attached to a landed commit. The event listener needs a way to gather all information related to a review. Currently there seems to be no method to get the necessary information.
epriestley suggested in IRC that a 'differential.querytransactions' method could be added after T2222 has been implemented.
