2989 # 2. $lastpush_hash: the suite branch on the dgit git server
2990 # 3. $lastfetch_hash: our local tracking brach for the suite
2992 # These may all be distinct and need not be in any fast forward
2995 # If the dsc was pushed to this suite, then the server suite
2996 # branch will have been updated; but it might have been pushed to
2997 # a different suite and copied by the archive. Conversely a more
2998 # recent version may have been pushed with dgit but not appeared
2999 # in the archive (yet).
3001 # $lastfetch_hash may be awkward because archive imports
3002 # (particularly, imports of Dgit-less .dscs) are performed only as
3003 # needed on individual clients, so different clients may perform a
3004 # different subset of them - and these imports are only made
3005 # public during push. So $lastfetch_hash may represent a set of
3006 # imports different to a subsequent upload by a different dgit
3009 # Our approach is as follows:
3011 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
3012 # descendant of $dsc_hash, then it was pushed by a dgit user who
3013 # had based their work on $dsc_hash, so we should prefer it.
3014 # Otherwise, $dsc_hash was installed into this suite in the
3015 # archive other than by a dgit push, and (necessarily) after the
3016 # last dgit push into that suite (since a dgit push would have
3017 # been descended from the dgit server git branch); thus, in that
3018 # case, we prefer the archive's version (and produce a
3019 # pseudo-merge to overwrite the dgit server git branch).
3021 # (If there is no Dgit field in the archive's .dsc then
3022 # generate_commit_from_dsc uses the version numbers to decide
3023 # whether the suite branch or the archive is newer. If the suite
3024 # branch is newer it ignores the archive's .dsc; otherwise it
3025 # generates an import of the .dsc, and produces a pseudo-merge to
3026 # overwrite the suite branch with the archive contents.)
3028 # The outcome of that part of the algorithm is the `public view',
3029 # and is same for all dgit clients: it does not depend on any
3030 # unpublished history in the local tracking branch.
3032 # As between the public view and the local tracking branch: The
3033 # local tracking branch is only updated by dgit fetch, and
3034 # whenever dgit fetch runs it includes the public view in the
3035 # local tracking branch. Therefore if the public view is not
3036 # descended from the local tracking branch, the local tracking
3037 # branch must contain history which was imported from the archive
3038 # but never pushed; and, its tip is now out of date. So, we make
3039 # a pseudo-merge to overwrite the old imports and stitch the old
3042 # Finally: we do not necessarily reify the public view (as
3043 # described above). This is so that we do not end up stacking two
3044 # pseudo-merges. So what we actually do is figure out the inputs
3045 # to any public view pseudo-merge and put them in @mergeinputs.

5144 # to to the patch tip tree (ie the tree corresponding to the
5145 # current dpkg-committed patch series). For these purposes
5146 # `identical' disregards anything in debian/ - this wrinkle is
5147 # necessary because dpkg-source treates debian/ specially.
5149 # We can only traverse edges where at most one of the ancestors'
5150 # trees differs (in changes outside in debian/). And we cannot
5151 # handle edges which change .pc/ or debian/patches. To avoid
5152 # going down a rathole we avoid traversing edges which introduce
5153 # debian/rules or debian/control. And we set a limit on the
5154 # number of edges we are willing to look at.
5156 # If we succeed, we walk forwards again. For each traversed edge

5158 # C=T) to we do this:

5161 # After traversing PT, we git commit the changes which
5162 # should be contained within debian/patches.

5631 # Our git tree doesn't necessarily contain .pc. (Some versions of
5632 # dgit would include the .pc in the git tree.) If there isn't
5633 # one, we need to generate one by unpacking the patches that we
5636 # We first look for a .pc in the git tree. If there is one, we
5637 # will use it. (This is not the normal case.)
5639 # Otherwise need to regenerate .pc so that dpkg-source --commit
5640 # can work. We do this as follows:
5641 # 1. Collect all relevant .orig from parent directory
5642 # 2. Generate a debian.tar.gz out of
5643 # debian/{patches,rules,source/format,source/options}
5644 # 3. Generate a fake .dsc containing just these fields:
5645 # Format Source Version Files
5646 # 4. Extract the fake .dsc
5647 # Now the fake .dsc has a .pc directory.
5648 # (In fact we do this in every case, because in future we will
5649 # want to search for a good base commit for generating patches.)
5651 # Then we can actually do the dpkg-source --commit
5652 # 1. Make a new working tree with the same object
5653 # store as our main tree and check out the main
5655 # 2. Copy .pc from the fake's extraction, if necessary
5656 # 3. Run dpkg-source --commit
5657 # 4. If the result has changes to debian/, then
5658 # - git add them them
5659 # - git add .pc if we had a .pc in-tree
5661 # 5. If we had a .pc in-tree, delete it, and git commit
5662 # 6. Back in the main tree, fast forward to the new HEAD
5664 # Another situation we may have to cope with is gbp-style
5665 # patches-unapplied trees.
5667 # We would want to detect these, so we know to escape into
5668 # quilt_fixup_gbp. However, this is in general not possible.
5669 # Consider a package with a one patch which the dgit user reverts
5670 # (with git revert or the moral equivalent).
5672 # That is indistinguishable in contents from a patches-unapplied
5673 # tree. And looking at the history to distinguish them is not
5674 # useful because the user might have made a confusing-looking git
5675 # history structure (which ought to produce an error if dgit can't
5676 # cope, not a silent reintroduction of an unwanted patch).
5678 # So gbp users will have to pass an option. But we can usually
5679 # detect their failure to do so: if the tree is not a clean
5680 # patches-applied tree, quilt linearisation fails, but the tree
5681 # _is_ a clean patches-unapplied tree, we can suggest that maybe
5682 # they want --quilt=unapplied.
5684 # To help detect this, when we are extracting the fake dsc, we
5685 # first extract it with --skip-patches, and then apply the patches
5686 # afterwards with dpkg-source --before-build. That lets us save a
