From c163a36f0bd0e07ffb9ee7d4bfb22f1cbb38eef8 Mon Sep 17 00:00:00 2001 From: Florian Forster Date: Sun, 18 Jun 2006 16:54:16 +0200 Subject: [PATCH] Don't instantiate structures with FAMs. Since structures with `flexible array members' are an incomplete datatype ANSI C99 forbids creating instances of them. This patch removes such an instance from `diff-lib.c' and replaces it with a pointer to a `struct combine_diff_path'. Since all neccessary memory is allocated at once the number of calls to `xmalloc' is not increased. --- diff-lib.c | 41 ++++++++++++++++++++++------------------- 1 file changed, 22 insertions(+), 19 deletions(-) diff --git a/diff-lib.c b/diff-lib.c index 2183b41b..fdc11732 100644 --- a/diff-lib.c +++ b/diff-lib.c @@ -34,21 +34,23 @@ int run_diff_files(struct rev_info *revs, int silent_on_removed) continue; if (ce_stage(ce)) { - struct { - struct combine_diff_path p; - struct combine_diff_parent filler[5]; - } combine; + struct combine_diff_path *dpath; int num_compare_stages = 0; + size_t path_len; - combine.p.next = NULL; - combine.p.len = ce_namelen(ce); - combine.p.path = xmalloc(combine.p.len + 1); - memcpy(combine.p.path, ce->name, combine.p.len); - combine.p.path[combine.p.len] = 0; - combine.p.mode = 0; - memset(combine.p.sha1, 0, 20); - memset(&combine.p.parent[0], 0, - sizeof(combine.filler)); + path_len = ce_namelen(ce); + + dpath = xmalloc (combine_diff_path_size (5, path_len)); + dpath->path = (char *) &(dpath->parent[5]); + + dpath->next = NULL; + dpath->len = path_len; + memcpy(dpath->path, ce->name, path_len); + dpath->path[path_len] = '\0'; + dpath->mode = 0; + memset(dpath->sha1, 0, 20); + memset(&(dpath->parent[0]), 0, + sizeof(struct combine_diff_parent)*5); while (i < entries) { struct cache_entry *nce = active_cache[i]; @@ -64,11 +66,11 @@ int run_diff_files(struct rev_info *revs, int silent_on_removed) if (2 <= stage) { int mode = ntohl(nce->ce_mode); num_compare_stages++; - memcpy(combine.p.parent[stage-2].sha1, + memcpy(dpath->parent[stage-2].sha1, nce->sha1, 20); - combine.p.parent[stage-2].mode = + dpath->parent[stage-2].mode = canon_mode(mode); - combine.p.parent[stage-2].status = + dpath->parent[stage-2].status = DIFF_STATUS_MODIFIED; } @@ -83,13 +85,14 @@ int run_diff_files(struct rev_info *revs, int silent_on_removed) i--; if (revs->combine_merges && num_compare_stages == 2) { - show_combined_diff(&combine.p, 2, + show_combined_diff(dpath, 2, revs->dense_combined_merges, revs); - free(combine.p.path); + free(dpath); continue; } - free(combine.p.path); + free(dpath); + dpath = NULL; /* * Show the diff for the 'ce' if we found the one -- 2.11.0
