From 6a94fc1a00ae784b12e15f498a5afba4020377f9 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Tue, 5 Sep 2023 14:32:37 +0900 Subject: [PATCH v6 1/2] Rename wait events with more consistent camelcase style This will help in the introduction of more simplifications with the generation of wait event data using wait_event_names.txt. The event names used the same case-insensitive characters, hence applying lower() or upper() to the monitoring queries allows the detection of the same events as before this change. --- src/backend/libpq/pqmq.c | 2 +- src/backend/replication/walsender.c | 2 +- src/backend/storage/ipc/shm_mq.c | 6 +- .../utils/activity/wait_event_names.txt | 90 +++++++++---------- 4 files changed, 50 insertions(+), 50 deletions(-) 3.2% src/backend/storage/ipc/ 93.3% src/backend/utils/activity/ 3.3% src/backend/ diff --git a/src/backend/libpq/pqmq.c b/src/backend/libpq/pqmq.c index 253181f47a..38b042804c 100644 --- a/src/backend/libpq/pqmq.c +++ b/src/backend/libpq/pqmq.c @@ -182,7 +182,7 @@ mq_putmessage(char msgtype, const char *s, size_t len) break; (void) WaitLatch(MyLatch, WL_LATCH_SET | WL_EXIT_ON_PM_DEATH, 0, - WAIT_EVENT_MQ_PUT_MESSAGE); + WAIT_EVENT_MESSAGE_QUEUE_PUT_MESSAGE); ResetLatch(MyLatch); CHECK_FOR_INTERRUPTS(); } diff --git a/src/backend/replication/walsender.c b/src/backend/replication/walsender.c index 46e48492ac..e250b0567e 100644 --- a/src/backend/replication/walsender.c +++ b/src/backend/replication/walsender.c @@ -1654,7 +1654,7 @@ WalSndWaitForWal(XLogRecPtr loc) if (pq_is_send_pending()) wakeEvents |= WL_SOCKET_WRITEABLE; - WalSndWait(wakeEvents, sleeptime, WAIT_EVENT_WAL_SENDER_WAIT_WAL); + WalSndWait(wakeEvents, sleeptime, WAIT_EVENT_WAL_SENDER_WAIT_FOR_WAL); } /* reactivate latch so WalSndLoop knows to continue */ diff --git a/src/backend/storage/ipc/shm_mq.c b/src/backend/storage/ipc/shm_mq.c index d134a09a19..06d6b73527 100644 --- a/src/backend/storage/ipc/shm_mq.c +++ b/src/backend/storage/ipc/shm_mq.c @@ -1017,7 +1017,7 @@ shm_mq_send_bytes(shm_mq_handle *mqh, Size nbytes, const void *data, * cheaper than setting one that has been reset. */ (void) WaitLatch(MyLatch, WL_LATCH_SET | WL_EXIT_ON_PM_DEATH, 0, - WAIT_EVENT_MQ_SEND); + WAIT_EVENT_MESSAGE_QUEUE_SEND); /* Reset the latch so we don't spin. */ ResetLatch(MyLatch); @@ -1163,7 +1163,7 @@ shm_mq_receive_bytes(shm_mq_handle *mqh, Size bytes_needed, bool nowait, * setting one that has been reset. */ (void) WaitLatch(MyLatch, WL_LATCH_SET | WL_EXIT_ON_PM_DEATH, 0, - WAIT_EVENT_MQ_RECEIVE); + WAIT_EVENT_MESSAGE_QUEUE_RECEIVE); /* Reset the latch so we don't spin. */ ResetLatch(MyLatch); @@ -1252,7 +1252,7 @@ shm_mq_wait_internal(shm_mq *mq, PGPROC **ptr, BackgroundWorkerHandle *handle) /* Wait to be signaled. */ (void) WaitLatch(MyLatch, WL_LATCH_SET | WL_EXIT_ON_PM_DEATH, 0, - WAIT_EVENT_MQ_INTERNAL); + WAIT_EVENT_MESSAGE_QUEUE_INTERNAL); /* Reset the latch so we don't spin. */ ResetLatch(MyLatch); diff --git a/src/backend/utils/activity/wait_event_names.txt b/src/backend/utils/activity/wait_event_names.txt index 06a1a3df9b..ca28d9e764 100644 --- a/src/backend/utils/activity/wait_event_names.txt +++ b/src/backend/utils/activity/wait_event_names.txt @@ -45,15 +45,15 @@ Section: ClassName - WaitEventActivity WAIT_EVENT_ARCHIVER_MAIN ArchiverMain "Waiting in main loop of archiver process." -WAIT_EVENT_AUTOVACUUM_MAIN AutoVacuumMain "Waiting in main loop of autovacuum launcher process." -WAIT_EVENT_BGWRITER_HIBERNATE BgWriterHibernate "Waiting in background writer process, hibernating." -WAIT_EVENT_BGWRITER_MAIN BgWriterMain "Waiting in main loop of background writer process." +WAIT_EVENT_AUTOVACUUM_MAIN AutovacuumMain "Waiting in main loop of autovacuum launcher process." +WAIT_EVENT_BGWRITER_HIBERNATE BgwriterHibernate "Waiting in background writer process, hibernating." +WAIT_EVENT_BGWRITER_MAIN BgwriterMain "Waiting in main loop of background writer process."
