2727 # a different suite and copied by the archive. Conversely a more
2728 # recent version may have been pushed with dgit but not appeared
2729 # in the archive (yet).
2731 # $lastfetch_hash may be awkward because archive imports
2732 # (particularly, imports of Dgit-less .dscs) are performed only as
2733 # needed on individual clients, so different clients may perform a
2734 # different subset of them - and these imports are only made
2735 # public during push. So $lastfetch_hash may represent a set of
2736 # imports different to a subsequent upload by a different dgit
2739 # Our approach is as follows:
2741 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
2742 # descendant of $dsc_hash, then it was pushed by a dgit user who
2743 # had based their work on $dsc_hash, so we should prefer it.
2744 # Otherwise, $dsc_hash was installed into this suite in the
2745 # archive other than by a dgit push, and (necessarily) after the
2746 # last dgit push into that suite (since a dgit push would have
2747 # been descended from the dgit server git branch); thus, in that
2748 # case, we prefer the archive's version (and produce a
2749 # pseudo-merge to overwrite the dgit server git branch).
2751 # (If there is no Dgit field in the archive's .dsc then
2752 # generate_commit_from_dsc uses the version numbers to decide
2753 # whether the suite branch or the archive is newer. If the suite
2754 # branch is newer it ignores the archive's .dsc; otherwise it
2755 # generates an import of the .dsc, and produces a pseudo-merge to
2756 # overwrite the suite branch with the archive contents.)
2758 # The outcome of that part of the algorithm is the `public view',
2759 # and is same for all dgit clients: it does not depend on any
2760 # unpublished history in the local tracking branch.
2762 # As between the public view and the local tracking branch: The
2763 # local tracking branch is only updated by dgit fetch, and
2764 # whenever dgit fetch runs it includes the public view in the
2765 # local tracking branch. Therefore if the public view is not
2766 # descended from the local tracking branch, the local tracking
2767 # branch must contain history which was imported from the archive
2768 # but never pushed; and, its tip is now out of date. So, we make
2769 # a pseudo-merge to overwrite the old imports and stitch the old
2772 # Finally: we do not necessarily reify the public view (as
2773 # described above). This is so that we do not end up stacking two
2774 # pseudo-merges. So what we actually do is figure out the inputs

4640 # current dpkg-committed patch series). For these purposes

4642 # necessary because dpkg-source treates debian/ specially.
4644 # We can only traverse edges where at most one of the ancestors'
4645 # trees differs (in changes outside in debian/). And we cannot
4646 # handle edges which change .pc/ or debian/patches. To avoid
4647 # going down a rathole we avoid traversing edges which introduce
4648 # debian/rules or debian/control. And we set a limit on the
4649 # number of edges we are willing to look at.
4651 # If we succeed, we walk forwards again. For each traversed edge

4653 # C=T) to we do this:

4657 # should be contained within debian/patches.

5125 # git commit into a quilt patch with dpkg-source --commit
5126 # - otherwise convert all the differences in the tree into
5127 # a single git commit
5131 # Our git tree doesn't necessarily contain .pc. (Some versions of
5132 # dgit would include the .pc in the git tree.) If there isn't
5133 # one, we need to generate one by unpacking the patches that we
5136 # We first look for a .pc in the git tree. If there is one, we
5137 # will use it. (This is not the normal case.)
5139 # Otherwise need to regenerate .pc so that dpkg-source --commit
5140 # can work. We do this as follows:
5141 # 1. Collect all relevant .orig from parent directory
5142 # 2. Generate a debian.tar.gz out of
5143 # debian/{patches,rules,source/format,source/options}
5144 # 3. Generate a fake .dsc containing just these fields:
5145 # Format Source Version Files
5146 # 4. Extract the fake .dsc
5147 # Now the fake .dsc has a .pc directory.
5148 # (In fact we do this in every case, because in future we will
5149 # want to search for a good base commit for generating patches.)
5151 # Then we can actually do the dpkg-source --commit
5152 # 1. Make a new working tree with the same object
5153 # store as our main tree and check out the main
5155 # 2. Copy .pc from the fake's extraction, if necessary
5156 # 3. Run dpkg-source --commit
5157 # 4. If the result has changes to debian/, then
5158 # - git add them them
5159 # - git add .pc if we had a .pc in-tree
5161 # 5. If we had a .pc in-tree, delete it, and git commit
5162 # 6. Back in the main tree, fast forward to the new HEAD
5164 # Another situation we may have to cope with is gbp-style
5165 # patches-unapplied trees.
5167 # We would want to detect these, so we know to escape into
5168 # quilt_fixup_gbp. However, this is in general not possible.
5169 # Consider a package with a one patch which the dgit user reverts
5170 # (with git revert or the moral equivalent).
5172 # That is indistinguishable in contents from a patches-unapplied
5173 # tree. And looking at the history to distinguish them is not
5174 # useful because the user might have made a confusing-looking git
5175 # history structure (which ought to produce an error if dgit can't
5176 # cope, not a silent reintroduction of an unwanted patch).
5178 # So gbp users will have to pass an option. But we can usually
5179 # detect their failure to do so: if the tree is not a clean
5180 # patches-applied tree, quilt linearisation fails, but the tree
5181 # _is_ a clean patches-unapplied tree, we can suggest that maybe
5182 # they want --quilt=unapplied.
5184 # To help detect this, when we are extracting the fake dsc, we
5185 # first extract it with --skip-patches, and then apply the patches
5186 # afterwards with dpkg-source --before-build. That lets us save a
