3208 # a different suite and copied by the archive. Conversely a more
3209 # recent version may have been pushed with dgit but not appeared
3210 # in the archive (yet).
3212 # $lastfetch_hash may be awkward because archive imports
3213 # (particularly, imports of Dgit-less .dscs) are performed only as
3214 # needed on individual clients, so different clients may perform a
3215 # different subset of them - and these imports are only made
3216 # public during push. So $lastfetch_hash may represent a set of
3217 # imports different to a subsequent upload by a different dgit
3220 # Our approach is as follows:
3222 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
3223 # descendant of $dsc_hash, then it was pushed by a dgit user who
3224 # had based their work on $dsc_hash, so we should prefer it.
3225 # Otherwise, $dsc_hash was installed into this suite in the
3226 # archive other than by a dgit push, and (necessarily) after the
3227 # last dgit push into that suite (since a dgit push would have
3228 # been descended from the dgit server git branch); thus, in that
3229 # case, we prefer the archive's version (and produce a
3230 # pseudo-merge to overwrite the dgit server git branch).
3232 # (If there is no Dgit field in the archive's .dsc then
3233 # generate_commit_from_dsc uses the version numbers to decide
3234 # whether the suite branch or the archive is newer. If the suite
3235 # branch is newer it ignores the archive's .dsc; otherwise it
3236 # generates an import of the .dsc, and produces a pseudo-merge to
3237 # overwrite the suite branch with the archive contents.)
3239 # The outcome of that part of the algorithm is the `public view',
3240 # and is same for all dgit clients: it does not depend on any
3241 # unpublished history in the local tracking branch.
3243 # As between the public view and the local tracking branch: The
3244 # local tracking branch is only updated by dgit fetch, and
3245 # whenever dgit fetch runs it includes the public view in the
3246 # local tracking branch. Therefore if the public view is not
3247 # descended from the local tracking branch, the local tracking
3248 # branch must contain history which was imported from the archive
3249 # but never pushed; and, its tip is now out of date. So, we make
3250 # a pseudo-merge to overwrite the old imports and stitch the old
3253 # Finally: we do not necessarily reify the public view (as
3254 # described above). This is so that we do not end up stacking two
3255 # pseudo-merges. So what we actually do is figure out the inputs

5543 # Quilt patchification algorithm
5545 # We search backwards through the history of the main tree's HEAD
5546 # (T) looking for a start commit S whose tree object is identical
5547 # to to the patch tip tree (ie the tree corresponding to the
5548 # current dpkg-committed patch series). For these purposes
5549 # `identical' disregards anything in debian/ - this wrinkle is
5550 # necessary because dpkg-source treates debian/ specially.
5552 # We can only traverse edges where at most one of the ancestors'
5553 # trees differs (in changes outside in debian/). And we cannot
5554 # handle edges which change .pc/ or debian/patches. To avoid
5555 # going down a rathole we avoid traversing edges which introduce
5556 # debian/rules or debian/control. And we set a limit on the
5557 # number of edges we are willing to look at.
5559 # If we succeed, we walk forwards again. For each traversed edge
5560 # PC (with P parent, C child) (starting with P=S and ending with
5561 # C=T) to we do this:
5563 # - dpkg-source --commit with a patch name and message derived from C
5564 # After traversing PT, we git commit the changes which
5565 # should be contained within debian/patches.
5567 # The search for the path S..T is breadth-first. We maintain a
5568 # todo list containing search nodes. A search node identifies a
5569 # commit, and looks something like this:
5571 # Commit => $git_commit_id,
5572 # Child => $c, # or undef if P=T

6123 # Format Source Version Files
6124 # 4. Extract the fake .dsc
6125 # Now the fake .dsc has a .pc directory.
6126 # (In fact we do this in every case, because in future we will
6127 # want to search for a good base commit for generating patches.)
6129 # Then we can actually do the dpkg-source --commit
6130 # 1. Make a new working tree with the same object
6131 # store as our main tree and check out the main
6133 # 2. Copy .pc from the fake's extraction, if necessary
6134 # 3. Run dpkg-source --commit

6146 # quilt_fixup_gbp. However, this is in general not possible.
6147 # Consider a package with a one patch which the dgit user reverts

6150 # That is indistinguishable in contents from a patches-unapplied

6152 # useful because the user might have made a confusing-looking git
6153 # history structure (which ought to produce an error if dgit can't
6154 # cope, not a silent reintroduction of an unwanted patch).
6156 # So gbp users will have to pass an option. But we can usually
6157 # detect their failure to do so: if the tree is not a clean
6158 # patches-applied tree, quilt linearisation fails, but the tree
6159 # _is_ a clean patches-unapplied tree, we can suggest that maybe
6160 # they want --quilt=unapplied.
6162 # To help detect this, when we are extracting the fake dsc, we
6163 # first extract it with --skip-patches, and then apply the patches
