It is clear that the format of the file is:
- category

- Format in the system views.

Or perhaps it would be better to divide this file by sections (like
errcodes.txt) for each category so as we eliminate entirely the first
column?
Yeah, that could be an option. V3 is still using the category as the first
column
but I'm ok to change it by a section if you prefer (though I don't really see
the need).
It can make the file width shorter, at least..
Right.
[ .. thinks .. ]
+my $waitclass;
+my @wait_classes = ("PG_WAIT_ACTIVITY", "PG_WAIT_CLIENT", "PG_WAIT_IPC",
"PG_WAIT_TIMEOUT", "PG_WAIT_IO");
Actually, having a "Section" in waiteventnames.txt would remove the
need to store this knowledge in generate-waiteventnames.pl, which is
a duplicate of the txt contents. If somebody adds a new class in the
future, it would be necessary to update this path as well. Well, that
would not be a huge effort in itself, but IMO the script translating
the .txt to the docs and the code should have no need to know the
types of classes. I guess that a format like that would make the most
sense to me, then:
Section: ClassName PG_WAIT_CLASS_NAME
# ClassName would be "IO", "IPC", "Timeout", etc.
WAIT_EVENT_NAME_1 "WaitEventName1" "Description of wait event 1"
WAIT_EVENT_NAME_N "WaitEventNameN" "Description of wait event N"
I gave another thought on it, and do agree that's better to use sections
in the .txt file. This is done in V4 attached.
utils/adt/jsonpath_scan.c \
+ utils/activity/waiteventnames.c \
+ utils/activity/waiteventnames.h \
+ utils/adt/jsonpath_scan.c \
Looks like a copy-pasto.
Why do you think so? both files have to be removed.
jsonpath_scan.c is listed twice, and that's still the case in v3.
Oh I see, I misunderstood what you thought the typo was.
Fixed in V4 thanks!
The
list of files deleted for maintainer-clean in src/backend/Makefile
should be listed alphabetically (utils/activity/ before utils/adt/),
but that's a nit ;)
Oh right, fixed.

Subject: [PATCH v4] Generating wait_event_types.h, pgstat_wait_event.c and
waiteventnames.sgml
Purpose is to auto-generate those files based on the newly created
waiteventnames.txt file.
Having auto generated files would help to avoid:
- wait event without description like observed in
https://www.postgresql.org/message-id/CA%2BhUKGJixAHc860Ej9Qzd_z96Z6aoajAgJ18bYfV3Lfn6t9%3D%2BQ%40mail.gmail.com
- orphaned wait event like observed in
https://www.postgresql.org/message-id/CA%2BhUKGK6tqm59KuF1z%2Bh5Y8fsWcu5v8%2B84kduSHwRzwjB2aa_A%40mail.gmail.com
