From 5540a635f2198c41a26f38a6057bbf146b9291d3 Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Fri, 28 Feb 2025 16:56:48 +0200 Subject: [PATCH 1/3] Remove unused ShutdownLatchSupport() function The only caller was removed in commit 80a8f95b3b. I don't foresee needing it any time soon, and I'm working on some big changes in this area, so let's remove it out of the way. --- src/backend/storage/ipc/latch.c | 27 --------------------------- src/include/storage/latch.h | 1 - 2 files changed, 28 deletions(-) diff --git a/src/backend/storage/ipc/latch.c b/src/backend/storage/ipc/latch.c index 4572684f224..cd09a10f3d1 100644 --- a/src/backend/storage/ipc/latch.c +++ b/src/backend/storage/ipc/latch.c @@ -360,33 +360,6 @@ InitializeLatchWaitSet(void) Assert(latch_pos == LatchWaitSetLatchPos); } -void -ShutdownLatchSupport(void) -{ -#if defined(WAIT_USE_POLL) - pqsignal(SIGURG, SIG_IGN); -#endif - - if (LatchWaitSet) - { - FreeWaitEventSet(LatchWaitSet); - LatchWaitSet = NULL; - } - -#if defined(WAIT_USE_SELF_PIPE) - close(selfpipe_readfd); - close(selfpipe_writefd); - selfpipe_readfd = -1; - selfpipe_writefd = -1; - selfpipe_owner_pid = InvalidPid; -#endif - -#if defined(WAIT_USE_SIGNALFD) - close(signal_fd); - signal_fd = -1; -#endif -} - /* * Initialize a process-local latch. */ diff --git a/src/include/storage/latch.h b/src/include/storage/latch.h index bf568124df9..66e7a5b7c08 100644 --- a/src/include/storage/latch.h +++ b/src/include/storage/latch.h @@ -173,7 +173,6 @@ extern void OwnLatch(Latch *latch); extern void DisownLatch(Latch *latch); extern void SetLatch(Latch *latch); extern void ResetLatch(Latch *latch); -extern void ShutdownLatchSupport(void); extern WaitEventSet *CreateWaitEventSet(ResourceOwner resowner, int nevents); extern void FreeWaitEventSet(WaitEventSet *set); -- 2.39.5
