It could still be able to append WAIT_EVENT_ to the first column of the file. I'd just rather keep it shorter. > FWIW, I'm getting: > > $ git am v3-000* > Applying: Rename wait events with more consistent camelcase style > Applying: Remove column for wait event names in wait_event_names.txt > error: patch failed: src/backend/utils/activity/wait_event_names.txt:261 > error: src/backend/utils/activity/wait_event_names.txt: patch does not apply > Patch failed at 0002 Remove column for wait event names in > wait_event_names.txt That may be a bug in the matrix because of bb90022, as git am can be easily pissed. I am attaching a new patch series, but it does not seem to matter here. I have double-checked the docs generated, while on it, and I am not seeing anything missing, particularly for the LWLock and Lock parts.. -- Michael
From 7e221db0fe26f9d36df90202934f4177daa86ff7 Mon Sep 17 00:00:00 2001 From: Michael Paquier <mich...@paquier.xyz> Date: Mon, 28 Aug 2023 14:47:13 +0900 Subject: [PATCH v4 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/storage/ipc/shm_mq.c | 6 +- .../utils/activity/wait_event_names.txt | 90 +++++++++---------- 3 files changed, 49 insertions(+), 49 deletions(-) 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/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 13774254d2..0cace8f40a 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."

Subject: [PATCH v4 2/2] Remove column for wait event names in
wait_event_names.txt
This file is now made of two columns, removing the column listing the
descriptions for each wait event class:
- Typedef enum definition, without the prefix "WAIT_EVENT_", for
simplicity.
- Description in the documentation.
The wait event names are generated from the enum objects in camelcase, with
the underscores removed.
