When using git log, boundary commits (ie, those commits added by specifying --boundary) do not respect the order (e.g., --date-order, --topo-order). Consider the following commit history, where number indicates the order of the commit timestamps: <view with a fixed with font! 3's ancestor is 1, 6's ancestors are 4,5> 0----1----2----5 <--A \ \ 3----4----6 <--B Executing the following command: $ git log --boundary --date-order ^A B Should produce the following order (boundary commits shown with dashes): 6 -5 4 3 -1 However, it in fact produces: 6 4 3 -7 -1 Please advise.
