2726 # recent version may have been pushed with dgit but not appeared
2727 # in the archive (yet).
2729 # $lastfetch_hash may be awkward because archive imports
2730 # (particularly, imports of Dgit-less .dscs) are performed only as
2731 # needed on individual clients, so different clients may perform a
2732 # different subset of them - and these imports are only made
2733 # public during push. So $lastfetch_hash may represent a set of
2734 # imports different to a subsequent upload by a different dgit
2737 # Our approach is as follows:
2739 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
2740 # descendant of $dsc_hash, then it was pushed by a dgit user who
2741 # had based their work on $dsc_hash, so we should prefer it.
2742 # Otherwise, $dsc_hash was installed into this suite in the
2743 # archive other than by a dgit push, and (necessarily) after the
2744 # last dgit push into that suite (since a dgit push would have
2745 # been descended from the dgit server git branch); thus, in that
2746 # case, we prefer the archive's version (and produce a
2747 # pseudo-merge to overwrite the dgit server git branch).
2749 # (If there is no Dgit field in the archive's .dsc then
2750 # generate_commit_from_dsc uses the version numbers to decide
2751 # whether the suite branch or the archive is newer. If the suite
2752 # branch is newer it ignores the archive's .dsc; otherwise it
2753 # generates an import of the .dsc, and produces a pseudo-merge to
2754 # overwrite the suite branch with the archive contents.)
2756 # The outcome of that part of the algorithm is the `public view',
2757 # and is same for all dgit clients: it does not depend on any
2758 # unpublished history in the local tracking branch.
2760 # As between the public view and the local tracking branch: The
2761 # local tracking branch is only updated by dgit fetch, and
2762 # whenever dgit fetch runs it includes the public view in the
2763 # local tracking branch. Therefore if the public view is not
2764 # descended from the local tracking branch, the local tracking
2765 # branch must contain history which was imported from the archive
2766 # but never pushed; and, its tip is now out of date. So, we make
2767 # a pseudo-merge to overwrite the old imports and stitch the old
2770 # Finally: we do not necessarily reify the public view (as
2771 # described above). This is so that we do not end up stacking two
2772 # pseudo-merges. So what we actually do is figure out the inputs

4642 # current dpkg-committed patch series). For these purposes

4644 # necessary because dpkg-source treates debian/ specially.
4646 # We can only traverse edges where at most one of the ancestors'
4647 # trees differs (in changes outside in debian/). And we cannot
4648 # handle edges which change .pc/ or debian/patches. To avoid
4649 # going down a rathole we avoid traversing edges which introduce
4650 # debian/rules or debian/control. And we set a limit on the
4651 # number of edges we are willing to look at.
4653 # If we succeed, we walk forwards again. For each traversed edge

4655 # C=T) to we do this:

4659 # should be contained within debian/patches.

5127 # git commit into a quilt patch with dpkg-source --commit
5128 # - otherwise convert all the differences in the tree into

5133 # Our git tree doesn't necessarily contain .pc. (Some versions of
5134 # dgit would include the .pc in the git tree.) If there isn't
5135 # one, we need to generate one by unpacking the patches that we
5138 # We first look for a .pc in the git tree. If there is one, we
5139 # will use it. (This is not the normal case.)
5141 # Otherwise need to regenerate .pc so that dpkg-source --commit
5142 # can work. We do this as follows:
5143 # 1. Collect all relevant .orig from parent directory
5144 # 2. Generate a debian.tar.gz out of
5145 # debian/{patches,rules,source/format,source/options}
5146 # 3. Generate a fake .dsc containing just these fields:
5147 # Format Source Version Files
5148 # 4. Extract the fake .dsc
5149 # Now the fake .dsc has a .pc directory.
5150 # (In fact we do this in every case, because in future we will
5151 # want to search for a good base commit for generating patches.)
5153 # Then we can actually do the dpkg-source --commit
5154 # 1. Make a new working tree with the same object
5155 # store as our main tree and check out the main
5157 # 2. Copy .pc from the fake's extraction, if necessary
5158 # 3. Run dpkg-source --commit
5159 # 4. If the result has changes to debian/, then
5160 # - git add them them
5161 # - git add .pc if we had a .pc in-tree
5163 # 5. If we had a .pc in-tree, delete it, and git commit
5164 # 6. Back in the main tree, fast forward to the new HEAD
5166 # Another situation we may have to cope with is gbp-style
5167 # patches-unapplied trees.
5169 # We would want to detect these, so we know to escape into
5170 # quilt_fixup_gbp. However, this is in general not possible.
5171 # Consider a package with a one patch which the dgit user reverts
5172 # (with git revert or the moral equivalent).
5174 # That is indistinguishable in contents from a patches-unapplied
5175 # tree. And looking at the history to distinguish them is not
5176 # useful because the user might have made a confusing-looking git
5177 # history structure (which ought to produce an error if dgit can't
5178 # cope, not a silent reintroduction of an unwanted patch).
5180 # So gbp users will have to pass an option. But we can usually
5181 # detect their failure to do so: if the tree is not a clean
5182 # patches-applied tree, quilt linearisation fails, but the tree
5183 # _is_ a clean patches-unapplied tree, we can suggest that maybe
5184 # they want --quilt=unapplied.
5186 # To help detect this, when we are extracting the fake dsc, we
5187 # first extract it with --skip-patches, and then apply the patches
5188 # afterwards with dpkg-source --before-build. That lets us save a
