From 26936bfd9bde1ec46901bea3e53d4fb9ae1b4a4c Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 30 Jun 2014 12:58:51 -0400 Subject: use strip_suffix instead of ends_with in simple cases When stripping a suffix like: if (ends_with(str, "foo")) buf = xmemdupz(str, strlen(str) - 3); we can instead use strip_suffix to avoid the constant 3, which must match the literal "foo" (we sometimes use strlen("foo") instead, but that means we are repeating ourselves). The example above becomes: if (strip_suffix(str, "foo", &len)) buf = xmemdupz(str, len); This also saves a strlen(), since we calculate the string length when detecting the suffix. Note that in some cases we also switch from xstrndup to xmemdupz, which saves a further strlen call.
