Message-Id: <1452021465-17831-1-git-send-email-andi@firstfloor.org> Date: Tue, 5 Jan 2016 11:17:45 -0800 From: Andi Kleen <andi@...stfloor.org> To: acme@...nel.org Cc: jolsa@...nel.org, mingo@...nel.org, linux-kernel@...r.kernel.org, Andi Kleen <ak@...ux.intel.com> Subject: [PATCH] perf, tools, stat: Force C numeric locale for CSV mode From: Andi Kleen <ak@...ux.intel.com> Some locales print floating point numbers with a comma instead of a dot. This causes problems with CSV mode because it causes extra false CSV fields. Force the numeric locale to be always C in CSV mode. Before: $ LC_ALL=pl_PL.utf8 perf stat -x, true 0,399472,,task-clock,399472,100,00 <---- extra bogus field ... After: $ LC_ALL=pl_PL.utf8 ./obj-perf/perf stat -x, true 0.338422,,task-clock,338422,100.00 Originally reported in https://github.com/andikleen/pmu-tools/issues/43 Signed-off-by: Andi Kleen <ak@...ux.intel.com> --- tools/perf/builtin-stat.c | 1 + 1 file changed, 1 insertion(+) diff --git a/tools/perf/builtin-stat.c b/tools/perf/builtin-stat.c index 9805e03..4d5e504 100644 --- a/tools/perf/builtin-stat.c +++ b/tools/perf/builtin-stat.c @@ -1826,6 +1826,7 @@ int cmd_stat(int argc, const char **argv, const char *prefix __maybe_unused) csv_output = true; if (!strcmp(csv_sep, "\\t")) csv_sep = "\t"; + setlocale(LC_NUMERIC, "C"); } else csv_sep = DEFAULT_SEPARATOR; -- 2.4.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
