* Import: Use absurd `git apply' emulation if gbp pq import failsIan Jackson2016-10-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gbp import can fail due to git apply not understanding patches. This is #841867 (against dgit). The underlying problem is #841866 (in gbp pq) which exposes things like #841865 and #829067 (in git). I imagine there are other lurking incompatibilities between git-apply and dpkg-source. We could in principle reimplement the gbp patch metadata extraction. But that would be quite tiresome and have its own compatibility problems. The real problem is just `git apply'. (Indeed gbp already tries git apply without, and then with, a whitespace fix option.) We work around the trouble by providing our own implementation of `git apply'. Specifically: We try to do things the sane way (just running gbp pq import) first. If that works, great. If it doesn't, we put /usr/share/dgit/absurd on the PATH. That contains only a sh script called `git'. This sh script figures out whether the caller is trying to invoke `git apply'. If not, it runs the real git. If the caller wanted git-apply, the absurd git script emulates it using dpkg-source --before-build. Conveniently, we know that the series file will not be touched by patches. So we can write just the patch we care about into the series file, and run --before-build, which applies just that one patch. The results are committed (minus the .pc), and for the next patch, dpkg-source sees again a tree with simply a single patch to apply. We try ordinary gbp pq first because our absurd approach is very slow on a big tree. Also we would like to maximise our chances of the import working. If git and/or gbp ever work better by themselves, all of this craziness will simply not happen. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

| | | | | | | | | | | The dgit-view ref is created by quiltify_splitbrain_needed, which is not always called. But, quiltify_splitbrain_needed's other function is to switch branches. If it was called then HEAD will refer to dgit-view. If it wasn't then the original HEAD is fine. Closes:#841770. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

* split brain cache: Add a dummy ref update when necessaryIan Jackson2016-10-20
| | | | | | | | | | | | | | | git-update-ref does not make a new reflog entry if the ref is not actually being changed. This can mean that `dgit build' might fail to find a good cache entry, but also fail to generate one that push will accept. In this case, generate a dummy reflog update. We make a spurious child of the $dgitview, as that's straightforward. Giving it the same tree and a parent means that human use of reflog commands will produce empty results rather than lots of confusing output.
