3083 # a different suite and copied by the archive. Conversely a more
3084 # recent version may have been pushed with dgit but not appeared
3085 # in the archive (yet).
3087 # $lastfetch_hash may be awkward because archive imports
3088 # (particularly, imports of Dgit-less .dscs) are performed only as
3089 # needed on individual clients, so different clients may perform a
3090 # different subset of them - and these imports are only made
3091 # public during push. So $lastfetch_hash may represent a set of
3092 # imports different to a subsequent upload by a different dgit
3095 # Our approach is as follows:
3097 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
3098 # descendant of $dsc_hash, then it was pushed by a dgit user who
3099 # had based their work on $dsc_hash, so we should prefer it.
3100 # Otherwise, $dsc_hash was installed into this suite in the
3101 # archive other than by a dgit push, and (necessarily) after the
3102 # last dgit push into that suite (since a dgit push would have
3103 # been descended from the dgit server git branch); thus, in that
3104 # case, we prefer the archive's version (and produce a
3105 # pseudo-merge to overwrite the dgit server git branch).
3107 # (If there is no Dgit field in the archive's .dsc then
3108 # generate_commit_from_dsc uses the version numbers to decide
3109 # whether the suite branch or the archive is newer. If the suite
3110 # branch is newer it ignores the archive's .dsc; otherwise it
3111 # generates an import of the .dsc, and produces a pseudo-merge to
3112 # overwrite the suite branch with the archive contents.)
3114 # The outcome of that part of the algorithm is the `public view',
3115 # and is same for all dgit clients: it does not depend on any
3116 # unpublished history in the local tracking branch.
3118 # As between the public view and the local tracking branch: The
3119 # local tracking branch is only updated by dgit fetch, and
3120 # whenever dgit fetch runs it includes the public view in the
3121 # local tracking branch. Therefore if the public view is not
3122 # descended from the local tracking branch, the local tracking
3123 # branch must contain history which was imported from the archive
3124 # but never pushed; and, its tip is now out of date. So, we make
3125 # a pseudo-merge to overwrite the old imports and stitch the old
3128 # Finally: we do not necessarily reify the public view (as
3129 # described above). This is so that we do not end up stacking two
3130 # pseudo-merges. So what we actually do is figure out the inputs
3131 # to any public view pseudo-merge and put them in @mergeinputs.

5394 # current dpkg-committed patch series). For these purposes

5396 # necessary because dpkg-source treates debian/ specially.
5398 # We can only traverse edges where at most one of the ancestors'
5399 # trees differs (in changes outside in debian/). And we cannot
5400 # handle edges which change .pc/ or debian/patches. To avoid
5401 # going down a rathole we avoid traversing edges which introduce
5402 # debian/rules or debian/control. And we set a limit on the
5403 # number of edges we are willing to look at.
5405 # If we succeed, we walk forwards again. For each traversed edge
5406 # PC (with P parent, C child) (starting with P=S and ending with
5407 # C=T) to we do this:
5409 # - dpkg-source --commit with a patch name and message derived from C
5410 # After traversing PT, we git commit the changes which
5411 # should be contained within debian/patches.

5932 # will use it. (This is not the normal case.)
5934 # Otherwise need to regenerate .pc so that dpkg-source --commit
5935 # can work. We do this as follows:
5936 # 1. Collect all relevant .orig from parent directory
5937 # 2. Generate a debian.tar.gz out of
5938 # debian/{patches,rules,source/format,source/options}

5940 # Format Source Version Files
5941 # 4. Extract the fake .dsc
5942 # Now the fake .dsc has a .pc directory.
5943 # (In fact we do this in every case, because in future we will
5944 # want to search for a good base commit for generating patches.)
5946 # Then we can actually do the dpkg-source --commit
5947 # 1. Make a new working tree with the same object
5948 # store as our main tree and check out the main
5950 # 2. Copy .pc from the fake's extraction, if necessary
5951 # 3. Run dpkg-source --commit
5952 # 4. If the result has changes to debian/, then
5953 # - git add them them
5954 # - git add .pc if we had a .pc in-tree
5956 # 5. If we had a .pc in-tree, delete it, and git commit
5957 # 6. Back in the main tree, fast forward to the new HEAD

5960 # patches-unapplied trees.
5962 # We would want to detect these, so we know to escape into
5963 # quilt_fixup_gbp. However, this is in general not possible.
5964 # Consider a package with a one patch which the dgit user reverts
5965 # (with git revert or the moral equivalent).
5967 # That is indistinguishable in contents from a patches-unapplied
5968 # tree. And looking at the history to distinguish them is not
5969 # useful because the user might have made a confusing-looking git
5970 # history structure (which ought to produce an error if dgit can't
5971 # cope, not a silent reintroduction of an unwanted patch).
5973 # So gbp users will have to pass an option. But we can usually
5974 # detect their failure to do so: if the tree is not a clean
5975 # patches-applied tree, quilt linearisation fails, but the tree
5976 # _is_ a clean patches-unapplied tree, we can suggest that maybe
5977 # they want --quilt=unapplied.
5979 # To help detect this, when we are extracting the fake dsc, we
