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3237 # unpublished history in the local tracking branch.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3245 # but never pushed; and, its tip is now out of date.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

5539 # Quilt patchification algorithm
5541 # We search backwards through the history of the main tree's HEAD
5542 # (T) looking for a start commit S whose tree object is identical
5543 # to to the patch tip tree (ie the tree corresponding to the
5544 # current dpkg-committed patch series). For these purposes
5545 # `identical' disregards anything in debian/ - this wrinkle is
5546 # necessary because dpkg-source treates debian/ specially.
5548 # We can only traverse edges where at most one of the ancestors'
5549 # trees differs (in changes outside in debian/). And we cannot
5550 # handle edges which change .pc/ or debian/patches. To avoid
5551 # going down a rathole we avoid traversing edges which introduce
5552 # debian/rules or debian/control. And we set a limit on the
5553 # number of edges we are willing to look at.
5555 # If we succeed, we walk forwards again. For each traversed edge
5556 # PC (with P parent, C child) (starting with P=S and ending with
5557 # C=T) to we do this:
5559 # - dpkg-source --commit with a patch name and message derived from C
5560 # After traversing PT, we git commit the changes which
5561 # should be contained within debian/patches.
5563 # The search for the path S..T is breadth-first. We maintain a
5564 # todo list containing search nodes. A search node identifies a
5565 # commit, and looks something like this:
5567 # Commit => $git_commit_id,
5568 # Child => $c, # or undef if P=T

6154 # want to search for a good base commit for generating patches.)

6157 # 1. Make a new working tree with the same object
6158 # store as our main tree and check out the main
6160 # 2. Copy .pc from the fake's extraction, if necessary
6161 # 3. Run dpkg-source --commit
6162 # 4. If the result has changes to debian/, then
6163 # - git add them them
6164 # - git add .pc if we had a .pc in-tree
6166 # 5. If we had a .pc in-tree, delete it, and git commit
6167 # 6. Back in the main tree, fast forward to the new HEAD
6169 # Another situation we may have to cope with is gbp-style
6170 # patches-unapplied trees.
6172 # We would want to detect these, so we know to escape into
