From 02b6ed91dd59ad0e2bf07dc46114f6954b34a292 Mon Sep 17 00:00:00 2001 From: Kyotaro Horiguchi Date: Mon, 16 Mar 2020 17:15:35 +0900 Subject: [PATCH v28 1/7] Use standard crash handler in archiver. The commit 8e19a82640 changed SIGQUIT handler of almost all processes not to run atexit callbacks for safety. Archiver process should behave the same way for the same reason. Exit status changes 1 to 2 but that doesn't make any behavioral change. --- src/backend/postmaster/pgarch.c | 11 +---------- 1 file changed, 1 insertion(+), 10 deletions(-) diff --git a/src/backend/postmaster/pgarch.c b/src/backend/postmaster/pgarch.c index 01ffd6513c..37be0e2bbb 100644 --- a/src/backend/postmaster/pgarch.c +++ b/src/backend/postmaster/pgarch.c @@ -96,7 +96,6 @@ static pid_t pgarch_forkexec(void); #endif NON_EXEC_STATIC void PgArchiverMain(int argc, char *argv[]) pg_attribute_noreturn(); -static void pgarch_exit(SIGNAL_ARGS); static void pgarch_waken(SIGNAL_ARGS); static void pgarch_waken_stop(SIGNAL_ARGS); static void pgarch_MainLoop(void); @@ -229,7 +228,7 @@ PgArchiverMain(int argc, char *argv[]) pqsignal(SIGHUP, SignalHandlerForConfigReload); pqsignal(SIGINT, SIG_IGN); pqsignal(SIGTERM, SignalHandlerForShutdownRequest); - pqsignal(SIGQUIT, pgarch_exit); + pqsignal(SIGQUIT, SignalHandlerForCrashExit); pqsignal(SIGALRM, SIG_IGN); pqsignal(SIGPIPE, SIG_IGN); pqsignal(SIGUSR1, pgarch_waken); @@ -246,14 +245,6 @@ PgArchiverMain(int argc, char *argv[]) exit(0); } -/* SIGQUIT signal handler for archiver process */ -static void -pgarch_exit(SIGNAL_ARGS) -{ - /* SIGQUIT means curl up and die ... */ - exit(1); -} - /* SIGUSR1 signal handler for archiver process */ static void pgarch_waken(SIGNAL_ARGS) -- 2.18.2
