2718 # recent version may have been pushed with dgit but not appeared
2719 # in the archive (yet).
2721 # $lastfetch_hash may be awkward because archive imports
2722 # (particularly, imports of Dgit-less .dscs) are performed only as
2723 # needed on individual clients, so different clients may perform a
2724 # different subset of them - and these imports are only made
2725 # public during push. So $lastfetch_hash may represent a set of
2726 # imports different to a subsequent upload by a different dgit
2729 # Our approach is as follows:
2731 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
2732 # descendant of $dsc_hash, then it was pushed by a dgit user who
2733 # had based their work on $dsc_hash, so we should prefer it.
2734 # Otherwise, $dsc_hash was installed into this suite in the
2735 # archive other than by a dgit push, and (necessarily) after the
2736 # last dgit push into that suite (since a dgit push would have
2737 # been descended from the dgit server git branch); thus, in that
2738 # case, we prefer the archive's version (and produce a
2739 # pseudo-merge to overwrite the dgit server git branch).
2741 # (If there is no Dgit field in the archive's .dsc then
2742 # generate_commit_from_dsc uses the version numbers to decide
2743 # whether the suite branch or the archive is newer. If the suite
2744 # branch is newer it ignores the archive's .dsc; otherwise it
2745 # generates an import of the .dsc, and produces a pseudo-merge to
2746 # overwrite the suite branch with the archive contents.)
2748 # The outcome of that part of the algorithm is the `public view',
2749 # and is same for all dgit clients: it does not depend on any
2750 # unpublished history in the local tracking branch.
2752 # As between the public view and the local tracking branch: The
2753 # local tracking branch is only updated by dgit fetch, and
2754 # whenever dgit fetch runs it includes the public view in the
2755 # local tracking branch. Therefore if the public view is not
2756 # descended from the local tracking branch, the local tracking
2757 # branch must contain history which was imported from the archive
2758 # but never pushed; and, its tip is now out of date. So, we make
2759 # a pseudo-merge to overwrite the old imports and stitch the old
2762 # Finally: we do not necessarily reify the public view (as
2763 # described above). This is so that we do not end up stacking two
2764 # pseudo-merges. So what we actually do is figure out the inputs
