1830 # 3. $lastfetch_hash: our local tracking brach for the suite
1832 # These may all be distinct and need not be in any fast forward
1835 # If the dsc was pushed to this suite, then the server suite
1836 # branch will have been updated; but it might have been pushed to
1837 # a different suite and copied by the archive. Conversely a more
1838 # recent version may have been pushed with dgit but not appeared
1839 # in the archive (yet).
1841 # $lastfetch_hash may be awkward because archive imports
1842 # (particularly, imports of Dgit-less .dscs) are performed only as
1843 # needed on individual clients, so different clients may perform a
1844 # different subset of them - and these imports are only made
1845 # public during push. So $lastfetch_hash may represent a set of
1846 # imports different to a subsequent upload by a different dgit
1849 # Our approach is as follows:
1851 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
1852 # descendant of $dsc_hash, then it was pushed by a dgit user who
1853 # had based their work on $dsc_hash, so we should prefer it.
1854 # Otherwise, $dsc_hash was installed into this suite in the
1855 # archive other than by a dgit push, and (necessarily) after the
1856 # last dgit push into that suite (since a dgit push would have
1857 # been descended from the dgit server git branch); thus, in that
1858 # case, we prefer the archive's version (and produce a
1859 # pseudo-merge to overwrite the dgit server git branch).
1861 # (If there is no Dgit field in the archive's .dsc then
1862 # generate_commit_from_dsc uses the version numbers to decide
1863 # whether the suite branch or the archive is newer. If the suite
1864 # branch is newer it ignores the archive's .dsc; otherwise it
1865 # generates an import of the .dsc, and produces a pseudo-merge to
1866 # overwrite the suite branch with the archive contents.)
1868 # The outcome of that part of the algorithm is the `public view',
1869 # and is same for all dgit clients: it does not depend on any
1870 # unpublished history in the local tracking branch.
1872 # As between the public view and the local tracking branch: The
1873 # local tracking branch is only updated by dgit fetch, and
1874 # whenever dgit fetch runs it includes the public view in the
1875 # local tracking branch. Therefore if the public view is not
1876 # descended from the local tracking branch, the local tracking
1877 # branch must contain history which was imported from the archive
1878 # but never pushed; and, its tip is now out of date. So, we make
1879 # a pseudo-merge to overwrite the old imports and stitch the old
1882 # Finally: we do not necessarily reify the public view (as
1883 # described above). This is so that we do not end up stacking two
1884 # pseudo-merges. So what we actually do is figure out the inputs
1885 # to any public view psuedo-merge and put them in @mergeinputs.

3259 # to to the patch tip tree (ie the tree corresponding to the
3260 # current dpkg-committed patch series). For these purposes
3261 # `identical' disregards anything in debian/ - this wrinkle is
3262 # necessary because dpkg-source treates debian/ specially.
3264 # We can only traverse edges where at most one of the ancestors'
3265 # trees differs (in changes outside in debian/). And we cannot
3266 # handle edges which change .pc/ or debian/patches. To avoid
3267 # going down a rathole we avoid traversing edges which introduce
3268 # debian/rules or debian/control. And we set a limit on the
3269 # number of edges we are willing to look at.
3271 # If we succeed, we walk forwards again. For each traversed edge
3272 # PC (with P parent, C child) (starting with P=S and ending with
3273 # C=T) to we do this:

3277 # should be contained within debian/patches.

3670 # git commit into a quilt patch with dpkg-source --commit
3671 # - otherwise convert all the differences in the tree into
3672 # a single git commit
3676 # Our git tree doesn't necessarily contain .pc. (Some versions of
3677 # dgit would include the .pc in the git tree.) If there isn't
3678 # one, we need to generate one by unpacking the patches that we
3681 # We first look for a .pc in the git tree. If there is one, we
3682 # will use it. (This is not the normal case.)
3684 # Otherwise need to regenerate .pc so that dpkg-source --commit
3685 # can work. We do this as follows:
3686 # 1. Collect all relevant .orig from parent directory
3687 # 2. Generate a debian.tar.gz out of
3688 # debian/{patches,rules,source/format,source/options}
3689 # 3. Generate a fake .dsc containing just these fields:
3690 # Format Source Version Files
3691 # 4. Extract the fake .dsc
3692 # Now the fake .dsc has a .pc directory.
3693 # (In fact we do this in every case, because in future we will
3694 # want to search for a good base commit for generating patches.)
3696 # Then we can actually do the dpkg-source --commit
3697 # 1. Make a new working tree with the same object
3698 # store as our main tree and check out the main
3700 # 2. Copy .pc from the fake's extraction, if necessary
3701 # 3. Run dpkg-source --commit
3702 # 4. If the result has changes to debian/, then
3703 # - git-add them them
3704 # - git-add .pc if we had a .pc in-tree
3706 # 5. If we had a .pc in-tree, delete it, and git-commit
3707 # 6. Back in the main tree, fast forward to the new HEAD
3709 # Another situation we may have to cope with is gbp-style
3710 # patches-unapplied trees.
3712 # We would want to detect these, so we know to escape into
3713 # quilt_fixup_gbp. However, this is in general not possible.
3714 # Consider a package with a one patch which the dgit user reverts
3715 # (with git-revert or the moral equivalent).
3717 # That is indistinguishable in contents from a patches-unapplied
3718 # tree. And looking at the history to distinguish them is not
3719 # useful because the user might have made a confusing-looking git
3720 # history structure (which ought to produce an error if dgit can't
3721 # cope, not a silent reintroduction of an unwanted patch).
3723 # So gbp users will have to pass an option. But we can usually
3724 # detect their failure to do so: if the tree is not a clean
3725 # patches-applied tree, quilt linearisation fails, but the tree
3726 # _is_ a clean patches-unapplied tree, we can suggest that maybe
3727 # they want --quilt=unapplied.
3729 # To help detect this, when we are extracting the fake dsc, we
3730 # first extract it with --skip-patches, and then apply the patches
3731 # afterwards with dpkg-source --before-build. That lets us save a
