2853 # current dpkg-committed patch series). For these purposes

2855 # necessary because dpkg-source treates debian/ specially.
2857 # We can only traverse edges where at most one of the ancestors'
2858 # trees differs (in changes outside in debian/). And we cannot
2859 # handle edges which change .pc/ or debian/patches. To avoid
2860 # going down a rathole we avoid traversing edges which introduce
2861 # debian/rules or debian/control. And we set a limit on the
2862 # number of edges we are willing to look at.
2864 # If we succeed, we walk forwards again. For each traversed edge

2866 # C=T) to we do this:

2870 # should be contained within debian/patches.

3274 # We first look for a .pc in the git tree. If there is one, we
3275 # will use it. (This is not the normal case.)
3277 # Otherwise need to regenerate .pc so that dpkg-source --commit
3278 # can work. We do this as follows:
3279 # 1. Collect all relevant .orig from parent directory
3280 # 2. Generate a debian.tar.gz out of
3281 # debian/{patches,rules,source/format,source/options}
3282 # 3. Generate a fake .dsc containing just these fields:
3283 # Format Source Version Files
3284 # 4. Extract the fake .dsc
3285 # Now the fake .dsc has a .pc directory.
3286 # (In fact we do this in every case, because in future we will
3287 # want to search for a good base commit for generating patches.)
3289 # Then we can actually do the dpkg-source --commit
3290 # 1. Make a new working tree with the same object
3291 # store as our main tree and check out the main
3293 # 2. Copy .pc from the fake's extraction, if necessary
3294 # 3. Run dpkg-source --commit
3295 # 4. If the result has changes to debian/, then
3296 # - git-add them them
3297 # - git-add .pc if we had a .pc in-tree
3299 # 5. If we had a .pc in-tree, delete it, and git-commit
3300 # 6. Back in the main tree, fast forward to the new HEAD
3302 # Another situation we may have to cope with is gbp-style
3303 # patches-unapplied trees.
3305 # We would want to detect these, so we know to escape into
3306 # quilt_fixup_gbp. However, this is in general not possible.
3307 # Consider a package with a one patch which the dgit user reverts
3308 # (with git-revert or the moral equivalent).
3310 # That is indistinguishable in contents from a patches-unapplied
3311 # tree. And looking at the history to distinguish them is not
3312 # useful because the user might have made a confusing-looking git
3313 # history structure (which ought to produce an error if dgit can't
3314 # cope, not a silent reintroduction of an unwanted patch).
3316 # So gbp users will have to pass an option. But we can usually
3317 # detect their failure to do so: if the tree is not a clean
3318 # patches-applied tree, quilt linearisation fails, but the tree
3319 # _is_ a clean patches-unapplied tree, we can suggest that maybe
3320 # they want --quilt=unapplied.
3322 # To help detect this, when we are extracting the fake dsc, we
3323 # first extract it with --skip-patches, and then apply the patches
3324 # afterwards with dpkg-source --before-build. That lets us save a
