In file bulk-checkin.c, three warnings are emitted by "-Wsign-compare", two of which are caused by trivial loop iterator type mismatches. For the third case, the type of `rsize` from ssize_t rsize = size < sizeof(ibuf) ? size : sizeof(ibuf); can be changed to size_t as both options of the ternary expression are unsigned and the signedness of the variable isn't really needed anywhere. To prevent `read_result != rsize` making a clash, it is to be noted that `read_result` is checked not to hold negative values. Therefore casting the variable to size_t is a safe operation and enough to remove the sign-compare warning.
Thanks, this description (and the matching changes in the patch) look good to me. -Peff
