date: use strbufs in date-formatting functions
Many of the date functions write into fixed-size buffers. This is a minor pain, as we have to take special precautions, and frequently end up copying the result into a strbuf or heap-allocated buffer anyway (for which we sometimes use strcpy!). Let's instead teach parse_date, datestamp, etc to write to a strbuf. The obvious downside is that we might need to perform a heap allocation where we otherwise would not need to. However, it turns out that the only two new allocations required are: 1. In test-date.c, where we don't care about efficiency. 2. In determine_author_info, which is not performance critical (and where the use of a strbuf will help later refactoring). Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
