2967 # 3. $lastfetch_hash: our local tracking brach for the suite
2969 # These may all be distinct and need not be in any fast forward
2972 # If the dsc was pushed to this suite, then the server suite
2973 # branch will have been updated; but it might have been pushed to
2974 # a different suite and copied by the archive. Conversely a more
2975 # recent version may have been pushed with dgit but not appeared
2976 # in the archive (yet).
2978 # $lastfetch_hash may be awkward because archive imports
2979 # (particularly, imports of Dgit-less .dscs) are performed only as
2980 # needed on individual clients, so different clients may perform a
2981 # different subset of them - and these imports are only made
2982 # public during push. So $lastfetch_hash may represent a set of
2983 # imports different to a subsequent upload by a different dgit
2986 # Our approach is as follows:
2988 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
2989 # descendant of $dsc_hash, then it was pushed by a dgit user who
2990 # had based their work on $dsc_hash, so we should prefer it.
2991 # Otherwise, $dsc_hash was installed into this suite in the
2992 # archive other than by a dgit push, and (necessarily) after the
2993 # last dgit push into that suite (since a dgit push would have
2994 # been descended from the dgit server git branch); thus, in that
2995 # case, we prefer the archive's version (and produce a
2996 # pseudo-merge to overwrite the dgit server git branch).
2998 # (If there is no Dgit field in the archive's .dsc then
2999 # generate_commit_from_dsc uses the version numbers to decide
3000 # whether the suite branch or the archive is newer. If the suite
3001 # branch is newer it ignores the archive's .dsc; otherwise it
3002 # generates an import of the .dsc, and produces a pseudo-merge to
3003 # overwrite the suite branch with the archive contents.)
3005 # The outcome of that part of the algorithm is the `public view',
3006 # and is same for all dgit clients: it does not depend on any
3007 # unpublished history in the local tracking branch.
3009 # As between the public view and the local tracking branch: The
3010 # local tracking branch is only updated by dgit fetch, and
3011 # whenever dgit fetch runs it includes the public view in the
3012 # local tracking branch. Therefore if the public view is not
3013 # descended from the local tracking branch, the local tracking
3014 # branch must contain history which was imported from the archive
3015 # but never pushed; and, its tip is now out of date. So, we make
3016 # a pseudo-merge to overwrite the old imports and stitch the old
3019 # Finally: we do not necessarily reify the public view (as
3020 # described above). This is so that we do not end up stacking two
3021 # pseudo-merges. So what we actually do is figure out the inputs
3022 # to any public view pseudo-merge and put them in @mergeinputs.

5018 # Quilt patchification algorithm
5020 # We search backwards through the history of the main tree's HEAD
5021 # (T) looking for a start commit S whose tree object is identical
5022 # to to the patch tip tree (ie the tree corresponding to the
5023 # current dpkg-committed patch series). For these purposes
5024 # `identical' disregards anything in debian/ - this wrinkle is
5025 # necessary because dpkg-source treates debian/ specially.
5027 # We can only traverse edges where at most one of the ancestors'
5028 # trees differs (in changes outside in debian/). And we cannot
5029 # handle edges which change .pc/ or debian/patches. To avoid
5030 # going down a rathole we avoid traversing edges which introduce
5031 # debian/rules or debian/control. And we set a limit on the
5032 # number of edges we are willing to look at.
5034 # If we succeed, we walk forwards again. For each traversed edge
5035 # PC (with P parent, C child) (starting with P=S and ending with
5036 # C=T) to we do this:
5038 # - dpkg-source --commit with a patch name and message derived from C
5039 # After traversing PT, we git commit the changes which
5040 # should be contained within debian/patches.
5042 # The search for the path S..T is breadth-first. We maintain a
5043 # todo list containing search nodes. A search node identifies a
5044 # commit, and looks something like this:
5046 # Commit => $git_commit_id,
5047 # Child => $c, # or undef if P=T

5517 # will use it. (This is not the normal case.)
5519 # Otherwise need to regenerate .pc so that dpkg-source --commit
5520 # can work. We do this as follows:
5521 # 1. Collect all relevant .orig from parent directory
5522 # 2. Generate a debian.tar.gz out of
5523 # debian/{patches,rules,source/format,source/options}

5525 # Format Source Version Files
5526 # 4. Extract the fake .dsc
5527 # Now the fake .dsc has a .pc directory.
5528 # (In fact we do this in every case, because in future we will
5529 # want to search for a good base commit for generating patches.)
5531 # Then we can actually do the dpkg-source --commit
5532 # 1. Make a new working tree with the same object
5533 # store as our main tree and check out the main
5535 # 2. Copy .pc from the fake's extraction, if necessary
5536 # 3. Run dpkg-source --commit
5537 # 4. If the result has changes to debian/, then
5538 # - git add them them
5539 # - git add .pc if we had a .pc in-tree
5541 # 5. If we had a .pc in-tree, delete it, and git commit
5542 # 6. Back in the main tree, fast forward to the new HEAD
5544 # Another situation we may have to cope with is gbp-style
5545 # patches-unapplied trees.
5547 # We would want to detect these, so we know to escape into
5548 # quilt_fixup_gbp. However, this is in general not possible.
5549 # Consider a package with a one patch which the dgit user reverts
5550 # (with git revert or the moral equivalent).
5552 # That is indistinguishable in contents from a patches-unapplied
5553 # tree. And looking at the history to distinguish them is not
5554 # useful because the user might have made a confusing-looking git
5555 # history structure (which ought to produce an error if dgit can't
5556 # cope, not a silent reintroduction of an unwanted patch).
5558 # So gbp users will have to pass an option. But we can usually
5559 # detect their failure to do so: if the tree is not a clean
5560 # patches-applied tree, quilt linearisation fails, but the tree
5561 # _is_ a clean patches-unapplied tree, we can suggest that maybe
5562 # they want --quilt=unapplied.
5564 # To help detect this, when we are extracting the fake dsc, we
5565 # first extract it with --skip-patches, and then apply the patches
