My strategy has always been "use the right repo if available, fall back to the_repo otherwise". This code path has struct repo, my mistake was not realize soon enough that there are two repos, not once (Ironically I made the conversion to add subrepo here). > It strikes me as a pretty important goal of this patch series to _not_ > change any behavior, and this bug makes me dubious that all diligence has > been done to assure that. Sooner or later all the_repo must be converted, what makes _this_ series different from other conversion series? Yes I slipped, I should have been more careful to the parts related to submodule. -- Duy
