# Quilt patchification algorithm
#
# We search backwards through the history of the main tree's HEAD
# (T) looking for a start commit S whose tree object is identical
# to to the patch tip tree (ie the tree corresponding to the
# current dpkg-committed patch series). For these purposes
# `identical' disregards anything in debian/ - this wrinkle is
# necessary because dpkg-source treates debian/ specially.
#
# We can only traverse edges where at most one of the ancestors'
# trees differs (in changes outside in debian/). And we cannot
# handle edges which change .pc/ or debian/patches. To avoid
# going down a rathole we avoid traversing edges which introduce
# debian/rules or debian/control. And we set a limit on the
# number of edges we are willing to look at.
#
# If we succeed, we walk forwards again. For each traversed edge
# PC (with P parent, C child) (starting with P=S and ending with
# C=T) to we do this:
# - git checkout C
# - dpkg-source --commit with a patch name and message derived from C
# After traversing PT, we git commit the changes which
# should be contained within debian/patches.
# The search for the path S..T is breadth-first. We maintain a
# todo list containing search nodes. A search node identifies a
# commit, and looks something like this:
# $p = {
# Commit => $git_commit_id,
# Child => $c, # or undef if P=T
# Whynot => $reason_edge_PC_unsuitable, # in @nots only

# 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,source/options}
# 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
# Another situation we may have to cope with is gbp-style
# patches-unapplied trees.
#
# We would want to detect these, so we know to escape into
# quilt_fixup_gbp. However, this is in general not possible.
# Consider a package with a one patch which the dgit user reverts
# (with git-revert or the moral equivalent).
#
# That is indistinguishable in contents from a patches-unapplied
# tree. And looking at the history to distinguish them is not
# useful because the user might have made a confusing-looking git
# history structure (which ought to produce an error if dgit can't
# cope, not a silent reintroduction of an unwanted patch).
#
# So gbp users will have to pass an option. But we can usually
# detect their failure to do so: if the tree is not a clean
# patches-applied tree, quilt linearisation fails, but the tree
# _is_ a clean patches-unapplied tree, we can suggest that maybe
# they want --quilt=unapplied.
#
# To help detect this, when we are extracting the fake dsc, we
# first extract it with --skip-patches, and then apply the patches
# afterwards with dpkg-source --before-build. That lets us save a
# tree object corresponding to .origs.
