This version has dropped some previous patches in favour of new ones. These solve the problem of atomically deciding what the head was before we updated it and also not reinventing the wheel for having an "create this ref, but if it already exists, fail silently" call. Since now both changes to remote set-head and fetch utilize some common preceding patches I have again included in this series my changes to remote set-head. Sorry for the mess tangent there. All tests (that run on my system) pass for the patches up to the last patch, which changes fetch. For the last patch I updated some of the test where it was trivial (lot of remote/HEAD -> something appeared as expected), but there is still work to be done there (i.e. figure out which tests need updating and which are actual bugs in the patch). One specific thing I wanted to mention here. Junio asked earlier what happens on fetch, when we have a config like this: > If I am only fetching refs (or HEAD) in FETCH_HEAD for immediate > consumtion by doing "git pull bence HEAD" with something like > > [remote "bence"] > URL = http://github.com/bence/git In this case setting head will error out with the generic error message I put at the end.
