3023 # If the dsc was pushed to this suite, then the server suite
3024 # branch will have been updated; but it might have been pushed to
3025 # a different suite and copied by the archive. Conversely a more
3026 # recent version may have been pushed with dgit but not appeared
3027 # in the archive (yet).
3029 # $lastfetch_hash may be awkward because archive imports
3030 # (particularly, imports of Dgit-less .dscs) are performed only as
3031 # needed on individual clients, so different clients may perform a
3032 # different subset of them - and these imports are only made
3033 # public during push. So $lastfetch_hash may represent a set of
3034 # imports different to a subsequent upload by a different dgit
3037 # Our approach is as follows:
3039 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
3040 # descendant of $dsc_hash, then it was pushed by a dgit user who
3041 # had based their work on $dsc_hash, so we should prefer it.
3042 # Otherwise, $dsc_hash was installed into this suite in the
3043 # archive other than by a dgit push, and (necessarily) after the
3044 # last dgit push into that suite (since a dgit push would have
3045 # been descended from the dgit server git branch); thus, in that
3046 # case, we prefer the archive's version (and produce a
3047 # pseudo-merge to overwrite the dgit server git branch).
3049 # (If there is no Dgit field in the archive's .dsc then
3050 # generate_commit_from_dsc uses the version numbers to decide
3051 # whether the suite branch or the archive is newer. If the suite
3052 # branch is newer it ignores the archive's .dsc; otherwise it
3053 # generates an import of the .dsc, and produces a pseudo-merge to
3054 # overwrite the suite branch with the archive contents.)
3056 # The outcome of that part of the algorithm is the `public view',
3057 # and is same for all dgit clients: it does not depend on any
3058 # unpublished history in the local tracking branch.
3060 # As between the public view and the local tracking branch: The
3061 # local tracking branch is only updated by dgit fetch, and
3062 # whenever dgit fetch runs it includes the public view in the
3063 # local tracking branch. Therefore if the public view is not
3064 # descended from the local tracking branch, the local tracking
3065 # branch must contain history which was imported from the archive
3066 # but never pushed; and, its tip is now out of date. So, we make
3067 # a pseudo-merge to overwrite the old imports and stitch the old
3070 # Finally: we do not necessarily reify the public view (as
3071 # described above). This is so that we do not end up stacking two
3072 # pseudo-merges. So what we actually do is figure out the inputs
3073 # to any public view pseudo-merge and put them in @mergeinputs.

5212 # current dpkg-committed patch series). For these purposes

5214 # necessary because dpkg-source treates debian/ specially.
5216 # We can only traverse edges where at most one of the ancestors'
5217 # trees differs (in changes outside in debian/). And we cannot
5218 # handle edges which change .pc/ or debian/patches. To avoid
5219 # going down a rathole we avoid traversing edges which introduce
5220 # debian/rules or debian/control. And we set a limit on the
5221 # number of edges we are willing to look at.
5223 # If we succeed, we walk forwards again. For each traversed edge

5225 # C=T) to we do this:

5229 # should be contained within debian/patches.

5718 # git commit into a quilt patch with dpkg-source --commit
5719 # - otherwise convert all the differences in the tree into

5724 # Our git tree doesn't necessarily contain .pc. (Some versions of

5729 # We first look for a .pc in the git tree. If there is one, we
5730 # will use it. (This is not the normal case.)
5732 # Otherwise need to regenerate .pc so that dpkg-source --commit
5733 # can work. We do this as follows:
5734 # 1. Collect all relevant .orig from parent directory
5735 # 2. Generate a debian.tar.gz out of
5736 # debian/{patches,rules,source/format,source/options}
5737 # 3. Generate a fake .dsc containing just these fields:
5738 # Format Source Version Files
5739 # 4. Extract the fake .dsc
5740 # Now the fake .dsc has a .pc directory.
5741 # (In fact we do this in every case, because in future we will
5742 # want to search for a good base commit for generating patches.)
5744 # Then we can actually do the dpkg-source --commit
5745 # 1. Make a new working tree with the same object
5746 # store as our main tree and check out the main
5748 # 2. Copy .pc from the fake's extraction, if necessary
5749 # 3. Run dpkg-source --commit
5750 # 4. If the result has changes to debian/, then
5751 # - git add them them
5752 # - git add .pc if we had a .pc in-tree
5754 # 5. If we had a .pc in-tree, delete it, and git commit
5755 # 6. Back in the main tree, fast forward to the new HEAD
5757 # Another situation we may have to cope with is gbp-style
5758 # patches-unapplied trees.
5760 # We would want to detect these, so we know to escape into
5761 # quilt_fixup_gbp. However, this is in general not possible.
5762 # Consider a package with a one patch which the dgit user reverts
5763 # (with git revert or the moral equivalent).
5765 # That is indistinguishable in contents from a patches-unapplied
5766 # tree. And looking at the history to distinguish them is not
5767 # useful because the user might have made a confusing-looking git
5768 # history structure (which ought to produce an error if dgit can't
5769 # cope, not a silent reintroduction of an unwanted patch).
5771 # So gbp users will have to pass an option. But we can usually
5772 # detect their failure to do so: if the tree is not a clean
5773 # patches-applied tree, quilt linearisation fails, but the tree
5774 # _is_ a clean patches-unapplied tree, we can suggest that maybe
5775 # they want --quilt=unapplied.
5777 # To help detect this, when we are extracting the fake dsc, we
5778 # first extract it with --skip-patches, and then apply the patches
5779 # afterwards with dpkg-source --before-build. That lets us save a
