2188 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
2189 # descendant of $dsc_hash, then it was pushed by a dgit user who
2190 # had based their work on $dsc_hash, so we should prefer it.
2191 # Otherwise, $dsc_hash was installed into this suite in the
2192 # archive other than by a dgit push, and (necessarily) after the
2193 # last dgit push into that suite (since a dgit push would have
2194 # been descended from the dgit server git branch); thus, in that
2195 # case, we prefer the archive's version (and produce a
2196 # pseudo-merge to overwrite the dgit server git branch).
2198 # (If there is no Dgit field in the archive's .dsc then
2199 # generate_commit_from_dsc uses the version numbers to decide
2200 # whether the suite branch or the archive is newer. If the suite
2201 # branch is newer it ignores the archive's .dsc; otherwise it
2202 # generates an import of the .dsc, and produces a pseudo-merge to
2203 # overwrite the suite branch with the archive contents.)
2205 # The outcome of that part of the algorithm is the `public view',
2206 # and is same for all dgit clients: it does not depend on any
2207 # unpublished history in the local tracking branch.
2209 # As between the public view and the local tracking branch: The
2210 # local tracking branch is only updated by dgit fetch, and
2211 # whenever dgit fetch runs it includes the public view in the
2212 # local tracking branch. Therefore if the public view is not
2213 # descended from the local tracking branch, the local tracking
2214 # branch must contain history which was imported from the archive
2215 # but never pushed; and, its tip is now out of date. So, we make
2216 # a pseudo-merge to overwrite the old imports and stitch the old
2219 # Finally: we do not necessarily reify the public view (as
2220 # described above). This is so that we do not end up stacking two
2221 # pseudo-merges. So what we actually do is figure out the inputs
2222 # to any public view pseudo-merge and put them in @mergeinputs.

3806 # We search backwards through the history of the main tree's HEAD

3808 # to to the patch tip tree (ie the tree corresponding to the
3809 # current dpkg-committed patch series). For these purposes
3810 # `identical' disregards anything in debian/ - this wrinkle is
3811 # necessary because dpkg-source treates debian/ specially.
3813 # We can only traverse edges where at most one of the ancestors'
3814 # trees differs (in changes outside in debian/). And we cannot
3815 # handle edges which change .pc/ or debian/patches. To avoid
3816 # going down a rathole we avoid traversing edges which introduce
3817 # debian/rules or debian/control. And we set a limit on the
3818 # number of edges we are willing to look at.
3820 # If we succeed, we walk forwards again. For each traversed edge

3822 # C=T) to we do this:

4273 # Consider a package with a one patch which the dgit user reverts
4274 # (with git-revert or the moral equivalent).
4276 # That is indistinguishable in contents from a patches-unapplied
4277 # tree. And looking at the history to distinguish them is not
4278 # useful because the user might have made a confusing-looking git
4279 # history structure (which ought to produce an error if dgit can't
4280 # cope, not a silent reintroduction of an unwanted patch).
4282 # So gbp users will have to pass an option. But we can usually
4283 # detect their failure to do so: if the tree is not a clean
4284 # patches-applied tree, quilt linearisation fails, but the tree
4285 # _is_ a clean patches-unapplied tree, we can suggest that maybe
4286 # they want --quilt=unapplied.
4288 # To help detect this, when we are extracting the fake dsc, we
4289 # first extract it with --skip-patches, and then apply the patches
4290 # afterwards with dpkg-source --before-build. That lets us save a
