From 6ae2568bc2367b4d47e0ea1cb043fd56e697912f Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 14 Oct 2020 19:04:19 -0400 Subject: remove unused SIGTIMER handler in timer_create this was leftover from when the actual SIGEV_THREAD timer logic was in the signal handler. commit 5b74eed3b301e2227385f3bf26d3bb7c2d822cf8 replaced that with use of sigwaitinfo, with the actual signal left blocked, so the no-op signal handler was no longer serving any purpose. the signal disposition reset to SIG_DFL is still needed, however, in case we inherited SIG_IGN from a foreign-libc process. --- src/time/timer_create.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) (limited to 'src/time') diff --git a/src/time/timer_create.c b/src/time/timer_create.c index 455d49fc..2b1ea170 100644 --- a/src/time/timer_create.c +++ b/src/time/timer_create.c @@ -32,15 +32,10 @@ static void cleanup_fromsig(void *p) longjmp(p, 1); } -static void timer_handler(int sig, siginfo_t *si, void *ctx) -{ -} - static void install_handler() { struct sigaction sa = { - .sa_sigaction = timer_handler, - .sa_flags = SA_SIGINFO | SA_RESTART + .sa_handler = SIG_DFL, }; __libc_sigaction(SIGTIMER, &sa, 0); } -- cgit v1.2.1
