1846 # These may all be distinct and need not be in any fast forward
1849 # If the dsc was pushed to this suite, then the server suite
1850 # branch will have been updated; but it might have been pushed to
1851 # a different suite and copied by the archive. Conversely a more
1852 # recent version may have been pushed with dgit but not appeared
1853 # in the archive (yet).
1855 # $lastfetch_hash may be awkward because archive imports
1856 # (particularly, imports of Dgit-less .dscs) are performed only as
1857 # needed on individual clients, so different clients may perform a
1858 # different subset of them - and these imports are only made
1859 # public during push. So $lastfetch_hash may represent a set of
1860 # imports different to a subsequent upload by a different dgit
1863 # Our approach is as follows:
1865 # As between $dsc_hash and $lastpush_hash: if $lastpush_hash is a
1866 # descendant of $dsc_hash, then it was pushed by a dgit user who
1867 # had based their work on $dsc_hash, so we should prefer it.
1868 # Otherwise, $dsc_hash was installed into this suite in the
1869 # archive other than by a dgit push, and (necessarily) after the
1870 # last dgit push into that suite (since a dgit push would have
1871 # been descended from the dgit server git branch); thus, in that
1872 # case, we prefer the archive's version (and produce a
1873 # pseudo-merge to overwrite the dgit server git branch).
1875 # (If there is no Dgit field in the archive's .dsc then
1876 # generate_commit_from_dsc uses the version numbers to decide
1877 # whether the suite branch or the archive is newer. If the suite
1878 # branch is newer it ignores the archive's .dsc; otherwise it
1879 # generates an import of the .dsc, and produces a pseudo-merge to
1880 # overwrite the suite branch with the archive contents.)
1882 # The outcome of that part of the algorithm is the `public view',
1883 # and is same for all dgit clients: it does not depend on any
1884 # unpublished history in the local tracking branch.
1886 # As between the public view and the local tracking branch: The
1887 # local tracking branch is only updated by dgit fetch, and
1888 # whenever dgit fetch runs it includes the public view in the
1889 # local tracking branch. Therefore if the public view is not
1890 # descended from the local tracking branch, the local tracking
1891 # branch must contain history which was imported from the archive
1892 # but never pushed; and, its tip is now out of date. So, we make
1893 # a pseudo-merge to overwrite the old imports and stitch the old
1896 # Finally: we do not necessarily reify the public view (as
1897 # described above). This is so that we do not end up stacking two
1898 # pseudo-merges. So what we actually do is figure out the inputs
1899 # to any public view pseudo-merge and put them in @mergeinputs.

3406 # going down a rathole we avoid traversing edges which introduce
3407 # debian/rules or debian/control. And we set a limit on the

3809 # git commit into a quilt patch with dpkg-source --commit
3810 # - otherwise convert all the differences in the tree into

3815 # Our git tree doesn't necessarily contain .pc. (Some versions of

3820 # We first look for a .pc in the git tree. If there is one, we
3821 # will use it. (This is not the normal case.)
3823 # Otherwise need to regenerate .pc so that dpkg-source --commit
3824 # can work. We do this as follows:
3825 # 1. Collect all relevant .orig from parent directory
3826 # 2. Generate a debian.tar.gz out of
3827 # debian/{patches,rules,source/format,source/options}
3828 # 3. Generate a fake .dsc containing just these fields:
3829 # Format Source Version Files
3830 # 4. Extract the fake .dsc
3831 # Now the fake .dsc has a .pc directory.
3832 # (In fact we do this in every case, because in future we will
3833 # want to search for a good base commit for generating patches.)
3835 # Then we can actually do the dpkg-source --commit
3836 # 1. Make a new working tree with the same object
3837 # store as our main tree and check out the main
3839 # 2. Copy .pc from the fake's extraction, if necessary
3840 # 3. Run dpkg-source --commit
3841 # 4. If the result has changes to debian/, then
3842 # - git-add them them
3843 # - git-add .pc if we had a .pc in-tree
3845 # 5. If we had a .pc in-tree, delete it, and git-commit
3846 # 6. Back in the main tree, fast forward to the new HEAD
3848 # Another situation we may have to cope with is gbp-style
3849 # patches-unapplied trees.
3851 # We would want to detect these, so we know to escape into
3852 # quilt_fixup_gbp. However, this is in general not possible.
3853 # Consider a package with a one patch which the dgit user reverts
3854 # (with git-revert or the moral equivalent).
3856 # That is indistinguishable in contents from a patches-unapplied
3857 # tree. And looking at the history to distinguish them is not
3858 # useful because the user might have made a confusing-looking git
3859 # history structure (which ought to produce an error if dgit can't
3860 # cope, not a silent reintroduction of an unwanted patch).
3862 # So gbp users will have to pass an option. But we can usually
3863 # detect their failure to do so: if the tree is not a clean
3864 # patches-applied tree, quilt linearisation fails, but the tree
3865 # _is_ a clean patches-unapplied tree, we can suggest that maybe
3866 # they want --quilt=unapplied.
3868 # To help detect this, when we are extracting the fake dsc, we
3869 # first extract it with --skip-patches, and then apply the patches
3870 # afterwards with dpkg-source --before-build. That lets us save a
