The read_cache() in prepare_to_commit() would end up clobbering the pointer we had for a previously populated "the_index.cache_tree" in the very common case of "git commit" stressed by e.g. the tests being changed here. We'd populate "the_index.cache_tree" by calling "update_main_cache_tree" in prepare_index(), but would not end up with a "fully prepared" index. What constitutes an existing index is clearly overly fuzzy, here we'll check "active_nr" (aka "the_index.cache_nr"), but our "the_index.cache_tree" might have been malloc()'d already. Thus the code added in11c8a74a64(commit: write cache-tree data when writing index anyway, 2011-12-06) would end up allocating the "cache_tree", and would interact here with code added in7168624c35(Do not generate full commit log message if it is not going to be used, 2007-11-28). The result was a very common memory leak. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Taylor Blau <me@ttaylorr.com>
