2655 # We search backwards through the history of the main tree's HEAD
2656 # (T) looking for a start commit S whose tree object is identical
2657 # to to the patch tip tree (ie the tree corresponding to the
2658 # current dpkg-committed patch series). For these purposes
2659 # `identical' disregards anything in debian/ - this wrinkle is
2660 # necessary because dpkg-source treates debian/ specially.
2662 # We can only traverse edges where at most one of the ancestors'
2663 # trees differs (in changes outside in debian/). And we cannot
2664 # handle edges which change .pc/ or debian/patches. To avoid
2665 # going down a rathole we avoid traversing edges which introduce
2666 # debian/rules or debian/control. And we set a limit on the
2667 # number of edges we are willing to look at.
2669 # If we succeed, we walk forwards again. For each traversed edge
2670 # PC (with P parent, C child) (starting with P=S and ending with
2671 # C=T) to we do this:
2673 # - dpkg-source --commit with a patch name and message derived from C
2674 # After traversing PT, we git commit the changes which
2675 # should be contained within debian/patches.

2965 # dgit would include the .pc in the git tree.) If there isn't
2966 # one, we need to generate one by unpacking the patches that we
2969 # We first look for a .pc in the git tree. If there is one, we
2970 # will use it. (This is not the normal case.)
2972 # Otherwise need to regenerate .pc so that dpkg-source --commit
2973 # can work. We do this as follows:
2974 # 1. Collect all relevant .orig from parent directory
2975 # 2. Generate a debian.tar.gz out of
2976 # debian/{patches,rules,source/format,source/options}
2977 # 3. Generate a fake .dsc containing just these fields:
2978 # Format Source Version Files
2979 # 4. Extract the fake .dsc
2980 # Now the fake .dsc has a .pc directory.
2981 # (In fact we do this in every case, because in future we will
2982 # want to search for a good base commit for generating patches.)
2984 # Then we can actually do the dpkg-source --commit
2985 # 1. Make a new working tree with the same object
2986 # store as our main tree and check out the main
2988 # 2. Copy .pc from the fake's extraction, if necessary
2989 # 3. Run dpkg-source --commit
2990 # 4. If the result has changes to debian/, then
2991 # - git-add them them
2992 # - git-add .pc if we had a .pc in-tree
2994 # 5. If we had a .pc in-tree, delete it, and git-commit
2995 # 6. Back in the main tree, fast forward to the new HEAD
2997 # Another situation we may have to cope with is gbp-style
2998 # patches-unapplied trees.
3000 # We would want to detect these, so we know to escape into
3001 # quilt_fixup_gbp. However, this is in general not possible.
3002 # Consider a package with a one patch which the dgit user reverts
3003 # (with git-revert or the moral equivalent).
3005 # That is indistinguishable in contents from a patches-unapplied
3006 # tree. And looking at the history to distinguish them is not
3007 # useful because the user might have made a confusing-looking git
3008 # history structure (which ought to produce an error if dgit can't
3009 # cope, not a silent reintroduction of an unwanted patch).
3011 # So gbp users will have to pass an option. But we can usually
3012 # detect their failure to do so: if the tree is not a clean
3013 # patches-applied tree, quilt linearisation fails, but the tree
3014 # _is_ a clean patches-unapplied tree, we can suggest that maybe
3015 # they want --quilt=unapplied.
3017 # To help detect this, when we are extracting the fake dsc, we
3018 # first extract it with --skip-patches, and then apply the patches
3019 # afterwards with dpkg-source --before-build. That lets us save a
3020 # tree object corresponding to .origs.
