Function lookup_replace_object

replace-object.h:45–53

* If object sha1 should be replaced, return the replacement object's * name (replaced recursively, if necessary). The return value is * either sha1 or a pointer to a permanently-allocated value. When * object replacement is suppressed, always return sha1. * * Note: some thread debuggers might point a data race on the * replace_map_initialized reading in this function. However, we know ther

 * it here (and it should be written to only once, anyway).
