From 3ffefb54c0515308ceafb6ba071567d9fd379498 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 10 Jun 2014 17:36:52 -0400 Subject: commit_tree: take a pointer/len pair rather than a const strbuf While strbufs are pretty common throughout our code, it is more flexible for functions to take a pointer/len pair than a strbuf. It's easy to turn a strbuf into such a pair (by dereferencing its members), but less easy to go the other way (you can strbuf_attach, but that has implications about memory ownership). This patch teaches commit_tree (and its associated callers and sub-functions) to take such a pair for the commit message rather than a strbuf. This makes passing the buffer around slightly more verbose, but means we can get rid of some dangerous strbuf_attach calls in the next patch.
