2891 # We first look for a .pc in the git tree. If there is one, we
2892 # will use it. (This is not the normal case.)
2894 # Otherwise need to regenerate .pc so that dpkg-source --commit
2895 # can work. We do this as follows:
2896 # 1. Collect all relevant .orig from parent directory
2897 # 2. Generate a debian.tar.gz out of
2898 # debian/{patches,rules,source/format,source/options}
2899 # 3. Generate a fake .dsc containing just these fields:
2900 # Format Source Version Files
2901 # 4. Extract the fake .dsc
2902 # Now the fake .dsc has a .pc directory.
2903 # (In fact we do this in every case, because in future we will
2904 # want to search for a good base commit for generating patches.)
2906 # Then we can actually do the dpkg-source --commit
2907 # 1. Make a new working tree with the same object
2908 # store as our main tree and check out the main
2910 # 2. Copy .pc from the fake's extraction, if necessary
2911 # 3. Run dpkg-source --commit
2912 # 4. If the result has changes to debian/, then
2913 # - git-add them them
2914 # - git-add .pc if we had a .pc in-tree
2916 # 5. If we had a .pc in-tree, delete it, and git-commit
2917 # 6. Back in the main tree, fast forward to the new HEAD
2919 # Another situation we may have to cope with is gbp-style
2920 # patches-unapplied trees.
2922 # We would want to detect these, so we know to escape into
2923 # quilt_fixup_gbp. However, this is in general not possible.
2924 # Consider a package with a one patch which the dgit user reverts
2925 # (with git-revert or the moral equivalent).
2927 # That is indistinguishable in contents from a patches-unapplied
2928 # tree. And looking at the history to distinguish them is not
2929 # useful because the user might have made a confusing-looking git
2930 # history structure (which ought to produce an error if dgit can't
2931 # cope, not a silent reintroduction of an unwanted patch).
2933 # So gbp users will have to pass an option. But we can usually
2934 # detect their failure to do so: if the tree is not a clean
2935 # patches-applied tree, quilt linearisation fails, but the tree
2936 # _is_ a clean patches-unapplied tree, we can suggest that maybe
2937 # they want --quilt=unapplied.
2939 # To help detect this, when we are extracting the fake dsc, we
2940 # first extract it with --skip-patches, and then apply the patches
2941 # afterwards with dpkg-source --before-build. That lets us save a
