From 43155cfe1415f5547791613a5de6399112ba3560 Mon Sep 17 00:00:00 2001 From: David Barr Date: Mon, 13 Dec 2010 17:09:31 +1100 Subject: [PATCH] vcs-svn: avoid using ls command twice Currently there are two functions to retrieve the mode and content at a path: const char *repo_read_path(const uint32_t *path); uint32_t repo_read_mode(const uint32_t *path) Replace them with a single function with two return values. This means we can use one round-trip to get the same information from fast-import that previously took two.
