When we want to know the push urls for a remote, there is some simple logic: - if the user configured any remote.*.pushurl keys, then those make the complete set of push urls - otherwise we push to all urls in remote.*.url Many spots implement this with a level of indirection, assigning to a local url/url_nr pair. But since both arrays are now strvecs, we can just use a pointer to select the appropriate strvec, shortening the code a bit. Even though this is now a one-liner, since it is application logic that is present in so many places, it's worth abstracting a helper function. In fact, we already have such a function, but it's local to builtin/push.c. So we'll just make it available everywhere via remote.h. There are two spots to pay special attention to here: 1. in builtin/remote.c's get_url(), we are selecting first based on push_mode and then falling back to "url" when we're in push_mode but no pushurl is defined. The updated code makes that much more clear, compared to the original which had an "else" fall-through. 2. likewise in that file's set_url(), we _only_ respect push_mode, sine the point is that we are adding to pushurl in that case (whether it is empty or not). And thus it does not use our helper function. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
