2936 # 2. $lastpush_hash: the suite branch on the dgit git server
2937 # 3. $lastfetch_hash: our local tracking brach for the suite
2939 # These may all be distinct and need not be in any fast forward
2942 # If the dsc was pushed to this suite, then the server suite
2943 # branch will have been updated; but it might have been pushed to
2944 # a different suite and copied by the archive. Conversely a more
2945 # recent version may have been pushed with dgit but not appeared
2946 # in the archive (yet).
2948 # $lastfetch_hash may be awkward because archive imports
2949 # (particularly, imports of Dgit-less .dscs) are performed only as
2950 # needed on individual clients, so different clients may perform a
2951 # different subset of them - and these imports are only made
2952 # public during push. So $lastfetch_hash may represent a set of
2953 # imports different to a subsequent upload by a different dgit
2956 # Our approach is as follows:
2958 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
2959 # descendant of $dsc_hash, then it was pushed by a dgit user who
2960 # had based their work on $dsc_hash, so we should prefer it.
2961 # Otherwise, $dsc_hash was installed into this suite in the
2962 # archive other than by a dgit push, and (necessarily) after the
2963 # last dgit push into that suite (since a dgit push would have
2964 # been descended from the dgit server git branch); thus, in that
2965 # case, we prefer the archive's version (and produce a
2966 # pseudo-merge to overwrite the dgit server git branch).
2968 # (If there is no Dgit field in the archive's .dsc then
2969 # generate_commit_from_dsc uses the version numbers to decide
2970 # whether the suite branch or the archive is newer. If the suite
2971 # branch is newer it ignores the archive's .dsc; otherwise it
2972 # generates an import of the .dsc, and produces a pseudo-merge to
2973 # overwrite the suite branch with the archive contents.)
2975 # The outcome of that part of the algorithm is the `public view',
2976 # and is same for all dgit clients: it does not depend on any
2977 # unpublished history in the local tracking branch.
2979 # As between the public view and the local tracking branch: The
2980 # local tracking branch is only updated by dgit fetch, and
2981 # whenever dgit fetch runs it includes the public view in the
2982 # local tracking branch. Therefore if the public view is not
2983 # descended from the local tracking branch, the local tracking
2984 # branch must contain history which was imported from the archive
2985 # but never pushed; and, its tip is now out of date. So, we make
2986 # a pseudo-merge to overwrite the old imports and stitch the old
2989 # Finally: we do not necessarily reify the public view (as
2990 # described above). This is so that we do not end up stacking two
2991 # pseudo-merges. So what we actually do is figure out the inputs
2992 # to any public view pseudo-merge and put them in @mergeinputs.

5048 # We search backwards through the history of the main tree's HEAD
5049 # (T) looking for a start commit S whose tree object is identical
5050 # to to the patch tip tree (ie the tree corresponding to the
5051 # current dpkg-committed patch series). For these purposes
5052 # `identical' disregards anything in debian/ - this wrinkle is
5053 # necessary because dpkg-source treates debian/ specially.
5055 # We can only traverse edges where at most one of the ancestors'
5056 # trees differs (in changes outside in debian/). And we cannot
5057 # handle edges which change .pc/ or debian/patches. To avoid
5058 # going down a rathole we avoid traversing edges which introduce
5059 # debian/rules or debian/control. And we set a limit on the
5060 # number of edges we are willing to look at.
5062 # If we succeed, we walk forwards again. For each traversed edge
5063 # PC (with P parent, C child) (starting with P=S and ending with
5064 # C=T) to we do this:
5066 # - dpkg-source --commit with a patch name and message derived from C
5067 # After traversing PT, we git commit the changes which
5068 # should be contained within debian/patches.

5557 # Now the fake .dsc has a .pc directory.
5558 # (In fact we do this in every case, because in future we will
5559 # want to search for a good base commit for generating patches.)

5562 # 1. Make a new working tree with the same object
5563 # store as our main tree and check out the main
5565 # 2. Copy .pc from the fake's extraction, if necessary
5566 # 3. Run dpkg-source --commit
5567 # 4. If the result has changes to debian/, then
5568 # - git add them them
5569 # - git add .pc if we had a .pc in-tree
5571 # 5. If we had a .pc in-tree, delete it, and git commit

5574 # Another situation we may have to cope with is gbp-style
5575 # patches-unapplied trees.
5577 # We would want to detect these, so we know to escape into
5578 # quilt_fixup_gbp. However, this is in general not possible.
5579 # Consider a package with a one patch which the dgit user reverts

5582 # That is indistinguishable in contents from a patches-unapplied
5583 # tree. And looking at the history to distinguish them is not
5584 # useful because the user might have made a confusing-looking git
5585 # history structure (which ought to produce an error if dgit can't
5586 # cope, not a silent reintroduction of an unwanted patch).
5588 # So gbp users will have to pass an option. But we can usually
5589 # detect their failure to do so: if the tree is not a clean
5590 # patches-applied tree, quilt linearisation fails, but the tree
5591 # _is_ a clean patches-unapplied tree, we can suggest that maybe
5592 # they want --quilt=unapplied.
5594 # To help detect this, when we are extracting the fake dsc, we
5595 # first extract it with --skip-patches, and then apply the patches
5596 # afterwards with dpkg-source --before-build. That lets us save a
