2710 # recent version may have been pushed with dgit but not appeared
2711 # in the archive (yet).
2713 # $lastfetch_hash may be awkward because archive imports
2714 # (particularly, imports of Dgit-less .dscs) are performed only as
2715 # needed on individual clients, so different clients may perform a
2716 # different subset of them - and these imports are only made
2717 # public during push. So $lastfetch_hash may represent a set of
2718 # imports different to a subsequent upload by a different dgit
2721 # Our approach is as follows:
2723 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
2724 # descendant of $dsc_hash, then it was pushed by a dgit user who
2725 # had based their work on $dsc_hash, so we should prefer it.
2726 # Otherwise, $dsc_hash was installed into this suite in the
2727 # archive other than by a dgit push, and (necessarily) after the
2728 # last dgit push into that suite (since a dgit push would have
2729 # been descended from the dgit server git branch); thus, in that
2730 # case, we prefer the archive's version (and produce a
2731 # pseudo-merge to overwrite the dgit server git branch).
2733 # (If there is no Dgit field in the archive's .dsc then
2734 # generate_commit_from_dsc uses the version numbers to decide
2735 # whether the suite branch or the archive is newer. If the suite
2736 # branch is newer it ignores the archive's .dsc; otherwise it
2737 # generates an import of the .dsc, and produces a pseudo-merge to
2738 # overwrite the suite branch with the archive contents.)
2740 # The outcome of that part of the algorithm is the `public view',
2741 # and is same for all dgit clients: it does not depend on any
2742 # unpublished history in the local tracking branch.
2744 # As between the public view and the local tracking branch: The
2745 # local tracking branch is only updated by dgit fetch, and
2746 # whenever dgit fetch runs it includes the public view in the
2747 # local tracking branch. Therefore if the public view is not
2748 # descended from the local tracking branch, the local tracking
2749 # branch must contain history which was imported from the archive
2750 # but never pushed; and, its tip is now out of date. So, we make
2751 # a pseudo-merge to overwrite the old imports and stitch the old
2754 # Finally: we do not necessarily reify the public view (as
2755 # described above). This is so that we do not end up stacking two
2756 # pseudo-merges. So what we actually do is figure out the inputs

4434 # We search backwards through the history of the main tree's HEAD
4435 # (T) looking for a start commit S whose tree object is identical
4436 # to to the patch tip tree (ie the tree corresponding to the
4437 # current dpkg-committed patch series). For these purposes
4438 # `identical' disregards anything in debian/ - this wrinkle is
4439 # necessary because dpkg-source treates debian/ specially.
4441 # We can only traverse edges where at most one of the ancestors'
4442 # trees differs (in changes outside in debian/). And we cannot
4443 # handle edges which change .pc/ or debian/patches. To avoid
4444 # going down a rathole we avoid traversing edges which introduce
4445 # debian/rules or debian/control. And we set a limit on the
4446 # number of edges we are willing to look at.
4448 # If we succeed, we walk forwards again. For each traversed edge
4449 # PC (with P parent, C child) (starting with P=S and ending with
4450 # C=T) to we do this:
4452 # - dpkg-source --commit with a patch name and message derived from C
4453 # After traversing PT, we git commit the changes which
4454 # should be contained within debian/patches.

4457 # todo list containing search nodes. A search node identifies a
4458 # commit, and looks something like this:

4965 # quilt_fixup_gbp. However, this is in general not possible.
4966 # Consider a package with a one patch which the dgit user reverts
4967 # (with git revert or the moral equivalent).
4969 # That is indistinguishable in contents from a patches-unapplied
4970 # tree. And looking at the history to distinguish them is not
4971 # useful because the user might have made a confusing-looking git
4972 # history structure (which ought to produce an error if dgit can't
4973 # cope, not a silent reintroduction of an unwanted patch).
4975 # So gbp users will have to pass an option. But we can usually
4976 # detect their failure to do so: if the tree is not a clean
4977 # patches-applied tree, quilt linearisation fails, but the tree
4978 # _is_ a clean patches-unapplied tree, we can suggest that maybe
4979 # they want --quilt=unapplied.
4981 # To help detect this, when we are extracting the fake dsc, we
4982 # first extract it with --skip-patches, and then apply the patches
4983 # afterwards with dpkg-source --before-build. That lets us save a
