From 59d3f541cfe48345d708330bc19d8a880c80c595 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Tue, 20 Feb 2007 01:08:48 +0100 Subject: [PATCH] name-rev: avoid "^0" when unneeded When naming by a tag, we used to add "^0" even if this was not really necessary. For example, `git name-rev de6f0def` now outputs de6f0def tags/v1.5.0.1~9 instead of de6f0def tags/v1.5.0.1^0~9 Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano --- builtin-name-rev.c | 23 ++++++++++++++++------- 1 file changed, 16 insertions(+), 7 deletions(-) diff --git a/builtin-name-rev.c b/builtin-name-rev.c index b4f15cc38..1b06b4afa 100644 --- a/builtin-name-rev.c +++ b/builtin-name-rev.c @@ -57,13 +57,17 @@ copy_data: parents; parents = parents->next, parent_number++) { if (parent_number > 1) { - char *new_name = xmalloc(strlen(tip_name)+8); + int len = strlen(tip_name); + char *new_name = xmalloc(len + 8); + if (len > 2 && !strcmp(tip_name + len - 2, "^0")) + len -= 2; if (generation > 0) - sprintf(new_name, "%s~%d^%d", tip_name, + sprintf(new_name, "%.*s~%d^%d", len, tip_name, generation, parent_number); else - sprintf(new_name, "%s^%d", tip_name, parent_number); + sprintf(new_name, "%.*s^%d", len, tip_name, + parent_number); name_rev(parents->item, new_name, merge_traversals + 1 , 0, 0); @@ -119,10 +123,15 @@ static const char* get_rev_name(struct object *o) if (!n->generation) return n->tip_name; - - snprintf(buffer, sizeof(buffer), "%s~%d", n->tip_name, n->generation); - - return buffer; + else { + int len = strlen(n->tip_name); + if (len > 2 && !strcmp(n->tip_name + len - 2, "^0")) + len -= 2; + snprintf(buffer, sizeof(buffer), "%.*s~%d", len, n->tip_name, + n->generation); + + return buffer; + } } int cmd_name_rev(int argc, const char **argv, const char *prefix) -- 2.26.2
