# Our objective is:
# - honour any existing .pc in case it has any strangeness
# - determine the git commit corresponding to the tip of
# the patch stack (if there is one)
# - if there is such a git commit, convert each subsequent
# git commit into a quilt patch with dpkg-source --commit
# - otherwise convert all the differences in the tree into
# a single git commit
#
# To do this we:
# Our git tree doesn't necessarily contain .pc. (Some versions of
# dgit would include the .pc in the git tree.) If there isn't
# one, we need to generate one by unpacking the patches that we
# have.
#
# We first look for a .pc in the git tree. If there is one, we
# will use it. (This is not the normal case.)
#
# Otherwise need to regenerate .pc so that dpkg-source --commit
# can work. We do this as follows:
# 1. Collect all relevant .orig from parent directory
# 2. Generate a debian.tar.gz out of
# debian/{patches,rules,source/format}
# 3. Generate a fake .dsc containing just these fields:
# Format Source Version Files
# 4. Extract the fake .dsc
# Now the fake .dsc has a .pc directory.
# (In fact we do this in every case, because in future we will
# want to search for a good base commit for generating patches.)
#
# Then we can actually do the dpkg-source --commit
# 1. Make a new working tree with the same object
# store as our main tree and check out the main
# tree's HEAD.
# 2. Copy .pc from the fake's extraction, if necessary
# 3. Run dpkg-source --commit
# 4. If the result has changes to debian/, then
# - git-add them them
# - git-add .pc if we had a .pc in-tree
# - git-commit
# 5. If we had a .pc in-tree, delete it, and git-commit
# 6. Back in the main tree, fast forward to the new HEAD
