From 0bdeb5e58d8fdf8b0f30461a388768112b0e080c Mon Sep 17 00:00:00 2001 From: David Lamparter Date: Sat, 6 May 2017 06:40:17 +0200 Subject: lib: rewrite zlog lock-free & TLS-buffered This is a full rewrite of the "back end" logging code. It now uses a lock-free list to iterate over logging targets, and the targets themselves are as lock-free as possible. (syslog() may have a hidden internal mutex in the C library; the file/fd targets use a single write() call which should ensure atomicity kernel-side.) Note that some functionality is lost in this patch: - Solaris printstack() backtraces are ditched (unlikely to come back) - the `log-filter` machinery is gone (re-added in followup commit) - `terminal monitor` is temporarily stubbed out. The old code had a race condition with VTYs going away. It'll likely come back rewritten and with vtysh support. - The `zebra_ext_log` hook is gone. Instead, it's now much easier to add a "proper" logging target. v2: TLS buffer to get some actual performance Signed-off-by: David Lamparter --- tests/lib/test_sig.c | 6 +----- 1 file changed, 1 insertion(+), 5 deletions(-) (limited to 'tests/lib/test_sig.c') diff --git a/tests/lib/test_sig.c b/tests/lib/test_sig.c index cf63a3d047..2aceafb8f0 100644 --- a/tests/lib/test_sig.c +++ b/tests/lib/test_sig.c @@ -57,11 +57,7 @@ int main(void) master = thread_master_create(NULL); signal_init(master, array_size(sigs), sigs); - openzlog("testsig", "NONE", 0, LOG_CONS | LOG_NDELAY | LOG_PID, - LOG_DAEMON); - zlog_set_level(ZLOG_DEST_SYSLOG, ZLOG_DISABLED); - zlog_set_level(ZLOG_DEST_STDOUT, LOG_DEBUG); - zlog_set_level(ZLOG_DEST_MONITOR, ZLOG_DISABLED); + zlog_aux_init("NONE: ", LOG_DEBUG); while (thread_fetch(master, &t)) thread_call(&t); -- cgit v1.2.3
