Fixes: #10938 Keep allocated memory when rhs fits Use case: Appending to a String with pre-allocated memory (e.g. from `reserve()`) No need to move 0-termination char in String::move Simplify calls to String::copy A lot of the same checks were done before calling `copy()` which should be done in the `copy()` function itself. String::copy() Should not copy more than given length Fix potential out of range in String::concat There is no prerequisite the given array has to be a 0-terminated char array. So we should only copy the length that has been given. The `setLen()` function will make sure the internal string is 0-terminated. So no need to dangerously assume there will be 1 more byte to copy Allow String::concat(const String &s) with s.buffer() == nullptr When constructing a String object, the internal buffer is a nullptr. However concatenating this to another String would return `false` while this is perfectly fine to do. |
