2615 # going down a rathole we avoid traversing edges which introduce
2616 # debian/rules or debian/control. And we set a limit on the
2617 # number of edges we are willing to look at.

2917 # We first look for a .pc in the git tree. If there is one, we
2918 # will use it. (This is not the normal case.)
2920 # Otherwise need to regenerate .pc so that dpkg-source --commit
2921 # can work. We do this as follows:
2922 # 1. Collect all relevant .orig from parent directory
2923 # 2. Generate a debian.tar.gz out of
2924 # debian/{patches,rules,source/format,source/options}
2925 # 3. Generate a fake .dsc containing just these fields:
2926 # Format Source Version Files
2927 # 4. Extract the fake .dsc
2928 # Now the fake .dsc has a .pc directory.
2929 # (In fact we do this in every case, because in future we will
2930 # want to search for a good base commit for generating patches.)
2932 # Then we can actually do the dpkg-source --commit
2933 # 1. Make a new working tree with the same object
2934 # store as our main tree and check out the main
2936 # 2. Copy .pc from the fake's extraction, if necessary
2937 # 3. Run dpkg-source --commit
2938 # 4. If the result has changes to debian/, then
2939 # - git-add them them
2940 # - git-add .pc if we had a .pc in-tree
2942 # 5. If we had a .pc in-tree, delete it, and git-commit
2943 # 6. Back in the main tree, fast forward to the new HEAD
2945 # Another situation we may have to cope with is gbp-style
2946 # patches-unapplied trees.
2948 # We would want to detect these, so we know to escape into
2949 # quilt_fixup_gbp. However, this is in general not possible.
2950 # Consider a package with a one patch which the dgit user reverts
2951 # (with git-revert or the moral equivalent).
2953 # That is indistinguishable in contents from a patches-unapplied
2954 # tree. And looking at the history to distinguish them is not
2955 # useful because the user might have made a confusing-looking git
2956 # history structure (which ought to produce an error if dgit can't
2957 # cope, not a silent reintroduction of an unwanted patch).
2959 # So gbp users will have to pass an option. But we can usually
2960 # detect their failure to do so: if the tree is not a clean
2961 # patches-applied tree, quilt linearisation fails, but the tree
2962 # _is_ a clean patches-unapplied tree, we can suggest that maybe
