This change is made so that gitk --all produces the same result for every user irrespective of whether git-rev-parse --all produces the same result for every user. By using --topo-order rather than --merge-order this can be guaranteed and the existing (non-timestamp dependent) behaviour of --merge-order can be maintained.
Signed-off-by: Jon Seymour <jon.seymour@gmail.com> --- Paul, could you review this patch and if you agree, ack it.
The rationale for changing gitk to use --topo-order is that git-rev-list will produce the same order for --topo-order irrespective of the order of the start list, whereas git-rev-list --merge-order produces an order that is deliberately sensitive to the order of the start list.
Linus wants gitk --all to behave the same way, irrespective of what order git-rev-parse --all produces its output. I want --merge-order to keep its existing behaviour, so we agreed on this compromise whereby gitk uses --topo-order rather than --merge-order by default.
My understanding of your code is that you only expect a minimal topological ordering guarantee and the ordering produced by --topo-order should be sufficient for your needs - that is, you don't rely on the other aspect of the --merge-order invariant.
I'll leave it to you and Linus to decide how you want to manage the merge between your HEAD and Linus'. ---
