2984 # 3. $lastfetch_hash: our local tracking brach for the suite
2986 # These may all be distinct and need not be in any fast forward
2989 # If the dsc was pushed to this suite, then the server suite
2990 # branch will have been updated; but it might have been pushed to
2991 # a different suite and copied by the archive. Conversely a more
2992 # recent version may have been pushed with dgit but not appeared
2993 # in the archive (yet).
2995 # $lastfetch_hash may be awkward because archive imports
2996 # (particularly, imports of Dgit-less .dscs) are performed only as
2997 # needed on individual clients, so different clients may perform a
2998 # different subset of them - and these imports are only made
2999 # public during push. So $lastfetch_hash may represent a set of
3000 # imports different to a subsequent upload by a different dgit
3003 # Our approach is as follows:
3005 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
3006 # descendant of $dsc_hash, then it was pushed by a dgit user who
3007 # had based their work on $dsc_hash, so we should prefer it.
3008 # Otherwise, $dsc_hash was installed into this suite in the
3009 # archive other than by a dgit push, and (necessarily) after the
3010 # last dgit push into that suite (since a dgit push would have
3011 # been descended from the dgit server git branch); thus, in that
3012 # case, we prefer the archive's version (and produce a
3013 # pseudo-merge to overwrite the dgit server git branch).
3015 # (If there is no Dgit field in the archive's .dsc then
3016 # generate_commit_from_dsc uses the version numbers to decide
3017 # whether the suite branch or the archive is newer. If the suite
3018 # branch is newer it ignores the archive's .dsc; otherwise it
3019 # generates an import of the .dsc, and produces a pseudo-merge to
3020 # overwrite the suite branch with the archive contents.)
3022 # The outcome of that part of the algorithm is the `public view',
3023 # and is same for all dgit clients: it does not depend on any
3024 # unpublished history in the local tracking branch.
3026 # As between the public view and the local tracking branch: The
3027 # local tracking branch is only updated by dgit fetch, and
3028 # whenever dgit fetch runs it includes the public view in the
3029 # local tracking branch. Therefore if the public view is not
3030 # descended from the local tracking branch, the local tracking
3031 # branch must contain history which was imported from the archive
3032 # but never pushed; and, its tip is now out of date. So, we make
3033 # a pseudo-merge to overwrite the old imports and stitch the old
3036 # Finally: we do not necessarily reify the public view (as
3037 # described above). This is so that we do not end up stacking two
3038 # pseudo-merges. So what we actually do is figure out the inputs
3039 # to any public view pseudo-merge and put them in @mergeinputs.

5093 # to to the patch tip tree (ie the tree corresponding to the
5094 # current dpkg-committed patch series). For these purposes
5095 # `identical' disregards anything in debian/ - this wrinkle is
5096 # necessary because dpkg-source treates debian/ specially.
5098 # We can only traverse edges where at most one of the ancestors'
5099 # trees differs (in changes outside in debian/). And we cannot
5100 # handle edges which change .pc/ or debian/patches. To avoid
5101 # going down a rathole we avoid traversing edges which introduce
5102 # debian/rules or debian/control. And we set a limit on the
5103 # number of edges we are willing to look at.
5105 # If we succeed, we walk forwards again. For each traversed edge
5106 # PC (with P parent, C child) (starting with P=S and ending with
5107 # C=T) to we do this:
5109 # - dpkg-source --commit with a patch name and message derived from C
5110 # After traversing PT, we git commit the changes which
5111 # should be contained within debian/patches.
