2954 # 3. $lastfetch_hash: our local tracking brach for the suite
2956 # These may all be distinct and need not be in any fast forward
2959 # If the dsc was pushed to this suite, then the server suite
2960 # branch will have been updated; but it might have been pushed to
2961 # a different suite and copied by the archive. Conversely a more
2962 # recent version may have been pushed with dgit but not appeared
2963 # in the archive (yet).
2965 # $lastfetch_hash may be awkward because archive imports
2966 # (particularly, imports of Dgit-less .dscs) are performed only as
2967 # needed on individual clients, so different clients may perform a
2968 # different subset of them - and these imports are only made
2969 # public during push. So $lastfetch_hash may represent a set of
2970 # imports different to a subsequent upload by a different dgit
2973 # Our approach is as follows:
2975 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
2976 # descendant of $dsc_hash, then it was pushed by a dgit user who
2977 # had based their work on $dsc_hash, so we should prefer it.
2978 # Otherwise, $dsc_hash was installed into this suite in the
2979 # archive other than by a dgit push, and (necessarily) after the
2980 # last dgit push into that suite (since a dgit push would have
2981 # been descended from the dgit server git branch); thus, in that
2982 # case, we prefer the archive's version (and produce a
2983 # pseudo-merge to overwrite the dgit server git branch).
2985 # (If there is no Dgit field in the archive's .dsc then
2986 # generate_commit_from_dsc uses the version numbers to decide
2987 # whether the suite branch or the archive is newer. If the suite
2988 # branch is newer it ignores the archive's .dsc; otherwise it
2989 # generates an import of the .dsc, and produces a pseudo-merge to
2990 # overwrite the suite branch with the archive contents.)
2992 # The outcome of that part of the algorithm is the `public view',
2993 # and is same for all dgit clients: it does not depend on any
2994 # unpublished history in the local tracking branch.
2996 # As between the public view and the local tracking branch: The
2997 # local tracking branch is only updated by dgit fetch, and
2998 # whenever dgit fetch runs it includes the public view in the
2999 # local tracking branch. Therefore if the public view is not
3000 # descended from the local tracking branch, the local tracking
3001 # branch must contain history which was imported from the archive
3002 # but never pushed; and, its tip is now out of date. So, we make
3003 # a pseudo-merge to overwrite the old imports and stitch the old
3006 # Finally: we do not necessarily reify the public view (as
3007 # described above). This is so that we do not end up stacking two
3008 # pseudo-merges. So what we actually do is figure out the inputs
3009 # to any public view pseudo-merge and put them in @mergeinputs.

4993 # Quilt patchification algorithm
4995 # We search backwards through the history of the main tree's HEAD
4996 # (T) looking for a start commit S whose tree object is identical
4997 # to to the patch tip tree (ie the tree corresponding to the
4998 # current dpkg-committed patch series). For these purposes
4999 # `identical' disregards anything in debian/ - this wrinkle is
5000 # necessary because dpkg-source treates debian/ specially.
5002 # We can only traverse edges where at most one of the ancestors'
5003 # trees differs (in changes outside in debian/). And we cannot
5004 # handle edges which change .pc/ or debian/patches. To avoid
5005 # going down a rathole we avoid traversing edges which introduce
5006 # debian/rules or debian/control. And we set a limit on the
5007 # number of edges we are willing to look at.
5009 # If we succeed, we walk forwards again. For each traversed edge
5010 # PC (with P parent, C child) (starting with P=S and ending with
5011 # C=T) to we do this:
5013 # - dpkg-source --commit with a patch name and message derived from C
5014 # After traversing PT, we git commit the changes which
5015 # should be contained within debian/patches.
5017 # The search for the path S..T is breadth-first. We maintain a
5018 # todo list containing search nodes. A search node identifies a
5019 # commit, and looks something like this:

5502 # Now the fake .dsc has a .pc directory.
5503 # (In fact we do this in every case, because in future we will
5504 # want to search for a good base commit for generating patches.)

5507 # 1. Make a new working tree with the same object
5508 # store as our main tree and check out the main
5510 # 2. Copy .pc from the fake's extraction, if necessary
5511 # 3. Run dpkg-source --commit

5527 # That is indistinguishable in contents from a patches-unapplied

5529 # useful because the user might have made a confusing-looking git
5530 # history structure (which ought to produce an error if dgit can't
5531 # cope, not a silent reintroduction of an unwanted patch).

5534 # detect their failure to do so: if the tree is not a clean
5535 # patches-applied tree, quilt linearisation fails, but the tree
