read-cache.c: fix memory leaks caused by removed cache entries
When cache_entry structs are removed from index_state.cache, they are not properly freed. Freeing those entries wasn't possible before because we couldn't remove them from index_state.name_hash. Now that we _do_ remove the entries from name_hash, we can also free them. Add 'free(cache_entry)' to all call sites of name-hash.c::remove_name_hash in read-cache.c (we could free() directly in remove_name_hash(), but name-hash.c isn't concerned with cache_entry allocation at all). Accessing a cache_entry after removing it from the index is now no longer allowed, as the memory has been freed. The following functions need minor fixes (typically by copying ce->name before use): - builtin/rm.c::cmd_rm - builtin/update-index.c::do_reupdate - read-cache.c::read_index_unmerged - resolve-undo.c::unmerge_index_entry_at Signed-off-by: Karsten Blees <blees@dcon.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
