2850 # to to the patch tip tree (ie the tree corresponding to the
2851 # current dpkg-committed patch series). For these purposes
2852 # `identical' disregards anything in debian/ - this wrinkle is
2853 # necessary because dpkg-source treates debian/ specially.
2855 # We can only traverse edges where at most one of the ancestors'
2856 # trees differs (in changes outside in debian/). And we cannot
2857 # handle edges which change .pc/ or debian/patches. To avoid
2858 # going down a rathole we avoid traversing edges which introduce
2859 # debian/rules or debian/control. And we set a limit on the
2860 # number of edges we are willing to look at.
2862 # If we succeed, we walk forwards again. For each traversed edge
2863 # PC (with P parent, C child) (starting with P=S and ending with
2864 # C=T) to we do this:

2867 # After traversing PT, we git commit the changes which
2868 # should be contained within debian/patches.

3272 # We first look for a .pc in the git tree. If there is one, we
3273 # will use it. (This is not the normal case.)
3275 # Otherwise need to regenerate .pc so that dpkg-source --commit
3276 # can work. We do this as follows:
3277 # 1. Collect all relevant .orig from parent directory
3278 # 2. Generate a debian.tar.gz out of
3279 # debian/{patches,rules,source/format,source/options}
3280 # 3. Generate a fake .dsc containing just these fields:
3281 # Format Source Version Files
3282 # 4. Extract the fake .dsc
3283 # Now the fake .dsc has a .pc directory.
3284 # (In fact we do this in every case, because in future we will
3285 # want to search for a good base commit for generating patches.)
3287 # Then we can actually do the dpkg-source --commit
3288 # 1. Make a new working tree with the same object
3289 # store as our main tree and check out the main
3291 # 2. Copy .pc from the fake's extraction, if necessary
3292 # 3. Run dpkg-source --commit
3293 # 4. If the result has changes to debian/, then
3294 # - git-add them them
3295 # - git-add .pc if we had a .pc in-tree
3297 # 5. If we had a .pc in-tree, delete it, and git-commit
3298 # 6. Back in the main tree, fast forward to the new HEAD
3300 # Another situation we may have to cope with is gbp-style
3301 # patches-unapplied trees.
3303 # We would want to detect these, so we know to escape into
3304 # quilt_fixup_gbp. However, this is in general not possible.
3305 # Consider a package with a one patch which the dgit user reverts
3306 # (with git-revert or the moral equivalent).
3308 # That is indistinguishable in contents from a patches-unapplied
3309 # tree. And looking at the history to distinguish them is not
3310 # useful because the user might have made a confusing-looking git
3311 # history structure (which ought to produce an error if dgit can't
3312 # cope, not a silent reintroduction of an unwanted patch).
3314 # So gbp users will have to pass an option. But we can usually
3315 # detect their failure to do so: if the tree is not a clean
3316 # patches-applied tree, quilt linearisation fails, but the tree
3317 # _is_ a clean patches-unapplied tree, we can suggest that maybe
3318 # they want --quilt=unapplied.
3320 # To help detect this, when we are extracting the fake dsc, we
3321 # first extract it with --skip-patches, and then apply the patches
3322 # afterwards with dpkg-source --before-build. That lets us save a
