Yes. I wanted to avoid nailing down the expected pathname until the code was in place that handled this case. merge-recursive currently elsewhere uses path~$BRANCH to workaround conflicting paths, but I had a (half-baked-so-far) idea for changing some of the path-conflict stuff which would involve different names. So, I just left it undecided until implemented. > * equally we'd want to have the submodule somewhere; you seem > to expect it at path (we could have moved it to path.sub or path.git, > but that involves extra work as we have to update the .gitmodules > file to have the correct path <->name mapping) Yes I wanted it at path for a specific reason: git can detect renames of files, and now of directories, but not of submodules, so it seems more important to keep the submodule where it is when possible. (merge_file_1() has code running counter to this, but that pre-dates submodules and should be updated, IMO.) > * good call with the index, I skimmed over the ls-files calls not thinking > what they'd check. > > So for now only the "file content is missing" part is failing the test, > whereas the rest is successful. > > Thanks for the explanation! > Stefan :-)
