3213 # recent version may have been pushed with dgit but not appeared
3214 # in the archive (yet).
3216 # $lastfetch_hash may be awkward because archive imports
3217 # (particularly, imports of Dgit-less .dscs) are performed only as
3218 # needed on individual clients, so different clients may perform a
3219 # different subset of them - and these imports are only made
3220 # public during push. So $lastfetch_hash may represent a set of
3221 # imports different to a subsequent upload by a different dgit
3224 # Our approach is as follows:
3226 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
3227 # descendant of $dsc_hash, then it was pushed by a dgit user who
3228 # had based their work on $dsc_hash, so we should prefer it.
3229 # Otherwise, $dsc_hash was installed into this suite in the
3230 # archive other than by a dgit push, and (necessarily) after the
3231 # last dgit push into that suite (since a dgit push would have
3232 # been descended from the dgit server git branch); thus, in that
3233 # case, we prefer the archive's version (and produce a
3234 # pseudo-merge to overwrite the dgit server git branch).
3236 # (If there is no Dgit field in the archive's .dsc then
3237 # generate_commit_from_dsc uses the version numbers to decide
3238 # whether the suite branch or the archive is newer. If the suite
3239 # branch is newer it ignores the archive's .dsc; otherwise it
3240 # generates an import of the .dsc, and produces a pseudo-merge to
3241 # overwrite the suite branch with the archive contents.)
3243 # The outcome of that part of the algorithm is the `public view',
3244 # and is same for all dgit clients: it does not depend on any
3245 # unpublished history in the local tracking branch.
3247 # As between the public view and the local tracking branch: The
3248 # local tracking branch is only updated by dgit fetch, and
3249 # whenever dgit fetch runs it includes the public view in the
3250 # local tracking branch. Therefore if the public view is not
3251 # descended from the local tracking branch, the local tracking
3252 # branch must contain history which was imported from the archive
3253 # but never pushed; and, its tip is now out of date. So, we make
3254 # a pseudo-merge to overwrite the old imports and stitch the old
3257 # Finally: we do not necessarily reify the public view (as
3258 # described above). This is so that we do not end up stacking two
3259 # pseudo-merges. So what we actually do is figure out the inputs

5547 # Quilt patchification algorithm
5549 # We search backwards through the history of the main tree's HEAD
5550 # (T) looking for a start commit S whose tree object is identical
5551 # to to the patch tip tree (ie the tree corresponding to the
5552 # current dpkg-committed patch series). For these purposes
5553 # `identical' disregards anything in debian/ - this wrinkle is
5554 # necessary because dpkg-source treates debian/ specially.
5556 # We can only traverse edges where at most one of the ancestors'
5557 # trees differs (in changes outside in debian/). And we cannot
5558 # handle edges which change .pc/ or debian/patches. To avoid
5559 # going down a rathole we avoid traversing edges which introduce
5560 # debian/rules or debian/control. And we set a limit on the
5561 # number of edges we are willing to look at.
5563 # If we succeed, we walk forwards again. For each traversed edge
5564 # PC (with P parent, C child) (starting with P=S and ending with
5565 # C=T) to we do this:
5567 # - dpkg-source --commit with a patch name and message derived from C
5568 # After traversing PT, we git commit the changes which
5569 # should be contained within debian/patches.
5571 # The search for the path S..T is breadth-first. We maintain a
5572 # todo list containing search nodes. A search node identifies a
5573 # commit, and looks something like this:
5575 # Commit => $git_commit_id,
5576 # Child => $c, # or undef if P=T

6165 # 1. Make a new working tree with the same object
6166 # store as our main tree and check out the main
6168 # 2. Copy .pc from the fake's extraction, if necessary
6169 # 3. Run dpkg-source --commit
6170 # 4. If the result has changes to debian/, then
6171 # - git add them them
6172 # - git add .pc if we had a .pc in-tree
6174 # 5. If we had a .pc in-tree, delete it, and git commit
6175 # 6. Back in the main tree, fast forward to the new HEAD
6177 # Another situation we may have to cope with is gbp-style
6178 # patches-unapplied trees.
6180 # We would want to detect these, so we know to escape into
