histedit: proper phase conservation (issue3724) Before this changeset, histedit created all new changesets according phases.new-commit option without any regards for the phases of the original changesets. This changeset fix that using the phase of rewritten changeset to decide the phase of the resulting changeset. In case of reordering or folding, we keep secret item secret as it seems the safer path. temporary commit creation are not affected. They are head only and stripped at the end of the histedit. As for the resolution of issue3681 (obsolescence cycle prevention), we do not handle changesets created by edit command.

test-histedit: reorder phases test and prepare for more We are going to add a lot regarding phase of test while fixing issue3724. This movement allows to put them after this first phase test.

test-histedit: fix instability creation test The current test does not rewrite anything and therefor does not create any instability. We also clean up the repo state after the test. This required the rebase extension.

histedit: record histedit source (issue3681) Have histedit record the hex of the original changeset as already done by: - graft - commit --amend - rebase My main motivation for adding this is to prevent the creation of obsolescence cycle (see issue3681). Note that commit created during edit are not affected yet.
