3205 # recent version may have been pushed with dgit but not appeared
3206 # in the archive (yet).
3208 # $lastfetch_hash may be awkward because archive imports
3209 # (particularly, imports of Dgit-less .dscs) are performed only as
3210 # needed on individual clients, so different clients may perform a
3211 # different subset of them - and these imports are only made
3212 # public during push. So $lastfetch_hash may represent a set of
3213 # imports different to a subsequent upload by a different dgit
3216 # Our approach is as follows:
3218 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
3219 # descendant of $dsc_hash, then it was pushed by a dgit user who
3220 # had based their work on $dsc_hash, so we should prefer it.
3221 # Otherwise, $dsc_hash was installed into this suite in the
3222 # archive other than by a dgit push, and (necessarily) after the
3223 # last dgit push into that suite (since a dgit push would have
3224 # been descended from the dgit server git branch); thus, in that
3225 # case, we prefer the archive's version (and produce a
3226 # pseudo-merge to overwrite the dgit server git branch).
3228 # (If there is no Dgit field in the archive's .dsc then
3229 # generate_commit_from_dsc uses the version numbers to decide
3230 # whether the suite branch or the archive is newer. If the suite
3231 # branch is newer it ignores the archive's .dsc; otherwise it
3232 # generates an import of the .dsc, and produces a pseudo-merge to
3233 # overwrite the suite branch with the archive contents.)
3235 # The outcome of that part of the algorithm is the `public view',
3236 # and is same for all dgit clients: it does not depend on any
3237 # unpublished history in the local tracking branch.
3239 # As between the public view and the local tracking branch: The
3240 # local tracking branch is only updated by dgit fetch, and
3241 # whenever dgit fetch runs it includes the public view in the
3242 # local tracking branch. Therefore if the public view is not
3243 # descended from the local tracking branch, the local tracking
3244 # branch must contain history which was imported from the archive
3245 # but never pushed; and, its tip is now out of date. So, we make
3246 # a pseudo-merge to overwrite the old imports and stitch the old
3249 # Finally: we do not necessarily reify the public view (as
3250 # described above). This is so that we do not end up stacking two
3251 # pseudo-merges. So what we actually do is figure out the inputs

5549 # Quilt patchification algorithm
5551 # We search backwards through the history of the main tree's HEAD
5552 # (T) looking for a start commit S whose tree object is identical
5553 # to to the patch tip tree (ie the tree corresponding to the
5554 # current dpkg-committed patch series). For these purposes
5555 # `identical' disregards anything in debian/ - this wrinkle is
5556 # necessary because dpkg-source treates debian/ specially.
5558 # We can only traverse edges where at most one of the ancestors'
5559 # trees differs (in changes outside in debian/). And we cannot
5560 # handle edges which change .pc/ or debian/patches. To avoid
5561 # going down a rathole we avoid traversing edges which introduce
5562 # debian/rules or debian/control. And we set a limit on the
5563 # number of edges we are willing to look at.
5565 # If we succeed, we walk forwards again. For each traversed edge
5566 # PC (with P parent, C child) (starting with P=S and ending with
5567 # C=T) to we do this:
5569 # - dpkg-source --commit with a patch name and message derived from C
5570 # After traversing PT, we git commit the changes which
5571 # should be contained within debian/patches.
5573 # The search for the path S..T is breadth-first. We maintain a
5574 # todo list containing search nodes. A search node identifies a
5575 # commit, and looks something like this:
5577 # Commit => $git_commit_id,
5578 # Child => $c, # or undef if P=T

6168 # store as our main tree and check out the main
6170 # 2. Copy .pc from the fake's extraction, if necessary
6171 # 3. Run dpkg-source --commit
6172 # 4. If the result has changes to debian/, then

6184 # Consider a package with a one patch which the dgit user reverts
6185 # (with git revert or the moral equivalent).
6187 # That is indistinguishable in contents from a patches-unapplied
6188 # tree. And looking at the history to distinguish them is not
6189 # useful because the user might have made a confusing-looking git
6190 # history structure (which ought to produce an error if dgit can't
6191 # cope, not a silent reintroduction of an unwanted patch).
6193 # So gbp users will have to pass an option. But we can usually
6194 # detect their failure to do so: if the tree is not a clean
6195 # patches-applied tree, quilt linearisation fails, but the tree
6196 # _is_ a clean patches-unapplied tree, we can suggest that maybe
6197 # they want --quilt=unapplied.
6199 # To help detect this, when we are extracting the fake dsc, we
6200 # first extract it with --skip-patches, and then apply the patches
6201 # afterwards with dpkg-source --before-build. That lets us save a
