Defined in:
lib/controller/book/refresh.rb

Overview

The refresh use case commits any changes made to the safe book into master. This is straightforward if the master’s state has not been forwarded by a ckeckin from another (shell) branch.

master and branch not in sync

Commits cannot occur when the master’s state has been moved forward by another branch commit. In these cases one needs to use the below sequence.

  • safe diff --refresh | diff will list what will the state changes during refresh

  • safe refresh | the actual merge down (from master to branch) that never deletes keys

  • safe commit | now the commit can proceed as the branch is in line with the master

refresh | merge up mechanics

The mechanics of a simple in-sync refresh is to

  • sync the master crypts to exactly mimic the branch crypts

  • tell master the content id of the book index file

  • tell master what the current random iv (initialization vector) is

  • create a new commit ID and set it on both master and branch

  • set the master’s last updated date and time
