3170 # a different suite and copied by the archive. Conversely a more
3171 # recent version may have been pushed with dgit but not appeared
3172 # in the archive (yet).
3174 # $lastfetch_hash may be awkward because archive imports
3175 # (particularly, imports of Dgit-less .dscs) are performed only as
3176 # needed on individual clients, so different clients may perform a
3177 # different subset of them - and these imports are only made
3178 # public during push. So $lastfetch_hash may represent a set of
3179 # imports different to a subsequent upload by a different dgit
3182 # Our approach is as follows:
3184 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
3185 # descendant of $dsc_hash, then it was pushed by a dgit user who
3186 # had based their work on $dsc_hash, so we should prefer it.
3187 # Otherwise, $dsc_hash was installed into this suite in the
3188 # archive other than by a dgit push, and (necessarily) after the
3189 # last dgit push into that suite (since a dgit push would have
3190 # been descended from the dgit server git branch); thus, in that
3191 # case, we prefer the archive's version (and produce a
3192 # pseudo-merge to overwrite the dgit server git branch).
3194 # (If there is no Dgit field in the archive's .dsc then
3195 # generate_commit_from_dsc uses the version numbers to decide
3196 # whether the suite branch or the archive is newer. If the suite
3197 # branch is newer it ignores the archive's .dsc; otherwise it
3198 # generates an import of the .dsc, and produces a pseudo-merge to
3199 # overwrite the suite branch with the archive contents.)
3201 # The outcome of that part of the algorithm is the `public view',
3202 # and is same for all dgit clients: it does not depend on any
3203 # unpublished history in the local tracking branch.
3205 # As between the public view and the local tracking branch: The
3206 # local tracking branch is only updated by dgit fetch, and
3207 # whenever dgit fetch runs it includes the public view in the
3208 # local tracking branch. Therefore if the public view is not
3209 # descended from the local tracking branch, the local tracking
3210 # branch must contain history which was imported from the archive
3211 # but never pushed; and, its tip is now out of date. So, we make
3212 # a pseudo-merge to overwrite the old imports and stitch the old
3215 # Finally: we do not necessarily reify the public view (as
3216 # described above). This is so that we do not end up stacking two
3217 # pseudo-merges. So what we actually do is figure out the inputs

5519 # debian/rules or debian/control. And we set a limit on the

6067 # 1. Collect all relevant .orig from parent directory
6068 # 2. Generate a debian.tar.gz out of

6071 # Format Source Version Files
6072 # 4. Extract the fake .dsc
6073 # Now the fake .dsc has a .pc directory.
6074 # (In fact we do this in every case, because in future we will
6075 # want to search for a good base commit for generating patches.)
6077 # Then we can actually do the dpkg-source --commit
6078 # 1. Make a new working tree with the same object
6079 # store as our main tree and check out the main
6081 # 2. Copy .pc from the fake's extraction, if necessary
6082 # 3. Run dpkg-source --commit
6083 # 4. If the result has changes to debian/, then

6085 # - git add .pc if we had a .pc in-tree
6087 # 5. If we had a .pc in-tree, delete it, and git commit

6095 # Consider a package with a one patch which the dgit user reverts

6098 # That is indistinguishable in contents from a patches-unapplied
6099 # tree. And looking at the history to distinguish them is not
6100 # useful because the user might have made a confusing-looking git
6101 # history structure (which ought to produce an error if dgit can't
6102 # cope, not a silent reintroduction of an unwanted patch).
6104 # So gbp users will have to pass an option. But we can usually
6105 # detect their failure to do so: if the tree is not a clean
6106 # patches-applied tree, quilt linearisation fails, but the tree
6107 # _is_ a clean patches-unapplied tree, we can suggest that maybe
6108 # they want --quilt=unapplied.
