1840 # These may all be distinct and need not be in any fast forward
1843 # If the dsc was pushed to this suite, then the server suite

1845 # a different suite and copied by the archive. Conversely a more
1846 # recent version may have been pushed with dgit but not appeared
1847 # in the archive (yet).
1849 # $lastfetch_hash may be awkward because archive imports
1850 # (particularly, imports of Dgit-less .dscs) are performed only as
1851 # needed on individual clients, so different clients may perform a
1852 # different subset of them - and these imports are only made
1853 # public during push. So $lastfetch_hash may represent a set of
1854 # imports different to a subsequent upload by a different dgit
1857 # Our approach is as follows:
1859 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
1860 # descendant of $dsc_hash, then it was pushed by a dgit user who
1861 # had based their work on $dsc_hash, so we should prefer it.
1862 # Otherwise, $dsc_hash was installed into this suite in the
1863 # archive other than by a dgit push, and (necessarily) after the
1864 # last dgit push into that suite (since a dgit push would have
1865 # been descended from the dgit server git branch); thus, in that
1866 # case, we prefer the archive's version (and produce a
1867 # pseudo-merge to overwrite the dgit server git branch).
1869 # (If there is no Dgit field in the archive's .dsc then
1870 # generate_commit_from_dsc uses the version numbers to decide
1871 # whether the suite branch or the archive is newer. If the suite
1872 # branch is newer it ignores the archive's .dsc; otherwise it
1873 # generates an import of the .dsc, and produces a pseudo-merge to
1874 # overwrite the suite branch with the archive contents.)
1876 # The outcome of that part of the algorithm is the `public view',
1877 # and is same for all dgit clients: it does not depend on any
1878 # unpublished history in the local tracking branch.
1880 # As between the public view and the local tracking branch: The
1881 # local tracking branch is only updated by dgit fetch, and
1882 # whenever dgit fetch runs it includes the public view in the
1883 # local tracking branch. Therefore if the public view is not
1884 # descended from the local tracking branch, the local tracking
1885 # branch must contain history which was imported from the archive
1886 # but never pushed; and, its tip is now out of date. So, we make
1887 # a pseudo-merge to overwrite the old imports and stitch the old
1890 # Finally: we do not necessarily reify the public view (as
1891 # described above). This is so that we do not end up stacking two
1892 # pseudo-merges. So what we actually do is figure out the inputs
1893 # to any public view psuedo-merge and put them in @mergeinputs.

3271 # to to the patch tip tree (ie the tree corresponding to the
3272 # current dpkg-committed patch series). For these purposes
3273 # `identical' disregards anything in debian/ - this wrinkle is
3274 # necessary because dpkg-source treates debian/ specially.
3276 # We can only traverse edges where at most one of the ancestors'
3277 # trees differs (in changes outside in debian/). And we cannot
3278 # handle edges which change .pc/ or debian/patches. To avoid
3279 # going down a rathole we avoid traversing edges which introduce
3280 # debian/rules or debian/control. And we set a limit on the
3281 # number of edges we are willing to look at.
3283 # If we succeed, we walk forwards again. For each traversed edge
3284 # PC (with P parent, C child) (starting with P=S and ending with
3285 # C=T) to we do this:

3288 # After traversing PT, we git commit the changes which
3289 # should be contained within debian/patches.

3682 # git commit into a quilt patch with dpkg-source --commit
3683 # - otherwise convert all the differences in the tree into
3684 # a single git commit
3688 # Our git tree doesn't necessarily contain .pc. (Some versions of
3689 # dgit would include the .pc in the git tree.) If there isn't
3690 # one, we need to generate one by unpacking the patches that we
3693 # We first look for a .pc in the git tree. If there is one, we
3694 # will use it. (This is not the normal case.)
3696 # Otherwise need to regenerate .pc so that dpkg-source --commit
3697 # can work. We do this as follows:
3698 # 1. Collect all relevant .orig from parent directory
3699 # 2. Generate a debian.tar.gz out of
3700 # debian/{patches,rules,source/format,source/options}
3701 # 3. Generate a fake .dsc containing just these fields:
3702 # Format Source Version Files
3703 # 4. Extract the fake .dsc
3704 # Now the fake .dsc has a .pc directory.
3705 # (In fact we do this in every case, because in future we will
3706 # want to search for a good base commit for generating patches.)
3708 # Then we can actually do the dpkg-source --commit
3709 # 1. Make a new working tree with the same object
3710 # store as our main tree and check out the main
3712 # 2. Copy .pc from the fake's extraction, if necessary
3713 # 3. Run dpkg-source --commit
3714 # 4. If the result has changes to debian/, then
3715 # - git-add them them
3716 # - git-add .pc if we had a .pc in-tree
3718 # 5. If we had a .pc in-tree, delete it, and git-commit
3719 # 6. Back in the main tree, fast forward to the new HEAD
3721 # Another situation we may have to cope with is gbp-style
3722 # patches-unapplied trees.
3724 # We would want to detect these, so we know to escape into
3725 # quilt_fixup_gbp. However, this is in general not possible.
3726 # Consider a package with a one patch which the dgit user reverts
3727 # (with git-revert or the moral equivalent).
3729 # That is indistinguishable in contents from a patches-unapplied
3730 # tree. And looking at the history to distinguish them is not
3731 # useful because the user might have made a confusing-looking git
3732 # history structure (which ought to produce an error if dgit can't
3733 # cope, not a silent reintroduction of an unwanted patch).
3735 # So gbp users will have to pass an option. But we can usually
3736 # detect their failure to do so: if the tree is not a clean
3737 # patches-applied tree, quilt linearisation fails, but the tree
3738 # _is_ a clean patches-unapplied tree, we can suggest that maybe
3739 # they want --quilt=unapplied.
3741 # To help detect this, when we are extracting the fake dsc, we
3742 # first extract it with --skip-patches, and then apply the patches
3743 # afterwards with dpkg-source --before-build. That lets us save a
