From c33ddc2e33d51da9391a81206a1d9e4a92d97d10 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 27 Aug 2014 03:57:08 -0400 Subject: 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).
