+ # 2. $lastpush_hash: the suite branch on the dgit git server
+ # 3. $lastfetch_hash: our local tracking brach for the suite
+ #
+ # These may all be distinct and need not be in any fast forward
+ # relationship:
+ #
+ # If the dsc was pushed to this suite, then the server suite
+ # branch will have been updated; but it might have been pushed to
+ # a different suite and copied by the archive. Conversely a more
+ # recent version may have been pushed with dgit but not appeared
+ # in the archive (yet).
+ #
+ # $lastfetch_hash may be awkward because archive imports
+ # (particularly, imports of Dgit-less .dscs) are performed only as
+ # needed on individual clients, so different clients may perform a
+ # different subset of them - and these imports are only made
+ # public during push. So $lastfetch_hash may represent a set of
+ # imports different to a subsequent upload by a different dgit
+ # client.
+ #
+ # Our approach is as follows:
+ #
+ # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
+ # descendant of $dsc_hash, then it was pushed by a dgit user who
+ # had based their work on $dsc_hash, so we should prefer it.
+ # Otherwise, $dsc_hash was installed into this suite in the
+ # archive other than by a dgit push, and (necessarily) after the
+ # last dgit push into that suite (since a dgit push would have
+ # been descended from the dgit server git branch); thus, in that
+ # case, we prefer the archive's version (and produce a
+ # pseudo-merge to overwrite the dgit server git branch).
+ #
+ # (If there is no Dgit field in the archive's .dsc then
+ # generate_commit_from_dsc uses the version numbers to decide
+ # whether the suite branch or the archive is newer. If the suite
+ # branch is newer it ignores the archive's .dsc; otherwise it
+ # generates an import of the .dsc, and produces a pseudo-merge to
+ # overwrite the suite branch with the archive contents.)
+ #
+ # The outcome of that part of the algorithm is the `public view',
+ # and is same for all dgit clients: it does not depend on any
+ # unpublished history in the local tracking branch.
+ #
+ # As between the public view and the local tracking branch: The
+ # local tracking branch is only updated by dgit fetch, and
+ # whenever dgit fetch runs it includes the public view in the
+ # local tracking branch. Therefore if the public view is not
+ # descended from the local tracking branch, the local tracking
+ # branch must contain history which was imported from the archive
+ # but never pushed; and, its tip is now out of date. So, we make
+ # a pseudo-merge to overwrite the old imports and stitch the old
+ # history in.
+ #
+ # Finally: we do not necessarily reify the public view (as
+ # described above). This is so that we do not end up stacking two
+ # pseudo-merges. So what we actually do is figure out the inputs
+ # to any public view pseudo-merge and put them in @mergeinputs.

+ # `identical' disregards anything in debian/ - this wrinkle is
+ # necessary because dpkg-source treates debian/ specially.
+ #
+ # We can only traverse edges where at most one of the ancestors'
+ # trees differs (in changes outside in debian/). And we cannot
+ # handle edges which change .pc/ or debian/patches. To avoid
+ # going down a rathole we avoid traversing edges which introduce
+ # debian/rules or debian/control. And we set a limit on the
+ # number of edges we are willing to look at.
+ #
+ # If we succeed, we walk forwards again. For each traversed edge
+ # PC (with P parent, C child) (starting with P=S and ending with
+ # C=T) to we do this:
+ # - git checkout C
+ # - dpkg-source --commit with a patch name and message derived from C
+ # After traversing PT, we git commit the changes which
+ # should be contained within debian/patches.

+ # Our objective is:
+ # - honour any existing .pc in case it has any strangeness
+ # - determine the git commit corresponding to the tip of
+ # the patch stack (if there is one)
+ # - if there is such a git commit, convert each subsequent
+ # git commit into a quilt patch with dpkg-source --commit
+ # - otherwise convert all the differences in the tree into
+ # a single git commit
+ #
+ # To do this we:
+
+ # Our git tree doesn't necessarily contain .pc. (Some versions of
+ # dgit would include the .pc in the git tree.) If there isn't
+ # one, we need to generate one by unpacking the patches that we
+ # have.
+ #
+ # We first look for a .pc in the git tree. If there is one, we
+ # will use it. (This is not the normal case.)
+ #
+ # Otherwise need to regenerate .pc so that dpkg-source --commit
+ # can work. We do this as follows:
+ # 1. Collect all relevant .orig from parent directory
+ # 2. Generate a debian.tar.gz out of
+ # debian/{patches,rules,source/format,source/options}
+ # 3. Generate a fake .dsc containing just these fields:
+ # Format Source Version Files
+ # 4. Extract the fake .dsc
+ # Now the fake .dsc has a .pc directory.
+ # (In fact we do this in every case, because in future we will
+ # want to search for a good base commit for generating patches.)
+ #
+ # Then we can actually do the dpkg-source --commit
+ # 1. Make a new working tree with the same object
+ # store as our main tree and check out the main
+ # tree's HEAD.
+ # 2. Copy .pc from the fake's extraction, if necessary
+ # 3. Run dpkg-source --commit
+ # 4. If the result has changes to debian/, then
+ # - git add them them
+ # - git add .pc if we had a .pc in-tree
+ # - git commit
+ # 5. If we had a .pc in-tree, delete it, and git commit
+ # 6. Back in the main tree, fast forward to the new HEAD
+
+ # Another situation we may have to cope with is gbp-style
+ # patches-unapplied trees.
+ #
+ # We would want to detect these, so we know to escape into
+ # quilt_fixup_gbp. However, this is in general not possible.
+ # Consider a package with a one patch which the dgit user reverts
+ # (with git revert or the moral equivalent).
+ #
+ # That is indistinguishable in contents from a patches-unapplied
+ # tree. And looking at the history to distinguish them is not
+ # useful because the user might have made a confusing-looking git
+ # history structure (which ought to produce an error if dgit can't
+ # cope, not a silent reintroduction of an unwanted patch).
+ #
+ # So gbp users will have to pass an option. But we can usually
+ # detect their failure to do so: if the tree is not a clean
+ # patches-applied tree, quilt linearisation fails, but the tree
+ # _is_ a clean patches-unapplied tree, we can suggest that maybe
+ # they want --quilt=unapplied.
+ #
+ # To help detect this, when we are extracting the fake dsc, we
+ # first extract it with --skip-patches, and then apply the patches
+ # afterwards with dpkg-source --before-build. That lets us save a
+ # tree object corresponding to .origs.
