From cef05e2a2b8aa70fa43496e3fdd6e0c5a0982e14 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Thu, 13 Jul 2023 10:14:47 +0900 Subject: [PATCH v2 4/4] Remove column for enum elements in wait_event_names.txt This file is now made of two columns, removing the column listing the enum elements for each wait event class: - Camelcase event name used in pg_stat_activity. There are now unquoted. - Description of the documentation. The enum elements are generated from what is now the first column. --- .../activity/generate-wait_event_types.pl | 24 +- .../utils/activity/wait_event_names.txt | 503 +++++++++--------- 2 files changed, 266 insertions(+), 261 deletions(-) diff --git a/src/backend/utils/activity/generate-wait_event_types.pl b/src/backend/utils/activity/generate-wait_event_types.pl index f63c991051..1d2489f268 100644 --- a/src/backend/utils/activity/generate-wait_event_types.pl +++ b/src/backend/utils/activity/generate-wait_event_types.pl @@ -73,20 +73,24 @@ my @lines_sorted = foreach my $line (@lines_sorted) { die "unable to parse wait_event_names.txt for line $line\n" - unless $line =~ /^(\w+)\t+(\w+)\t+(\w+)\t+("\w.*\.")$/; + unless $line =~ /^(\w+)\t+(\w+)\t+("\w.*\.")$/; - ( my $waitclassname, - my $waiteventenumname, - my $waiteventdescription, - my $waitevendocsentence) = split(/\t/, $line); + (my $waitclassname, my $waiteventdescription, my $waitevendocsentence) = + split(/\t/, $line); + # Generate the element name for the enums based on the + # description.
