From b9a270c72ede800f2819b326aef7a7144027d861 Mon Sep 17 00:00:00 2001 From: Bertrand Drouvot <bertranddrouvot...@gmail.com> Date: Sat, 22 Apr 2023 10:37:56 +0000 Subject: [PATCH v5] 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 --- doc/src/sgml/.gitignore | 1 + doc/src/sgml/Makefile | 5 +- doc/src/sgml/filelist.sgml | 1 + doc/src/sgml/meson.build | 10 + doc/src/sgml/monitoring.sgml | 792 +----------------- src/backend/Makefile | 13 +- src/backend/utils/activity/Makefile | 10 + .../utils/activity/generate-waiteventnames.pl | 204 +++++ src/backend/utils/activity/meson.build | 24 + src/backend/utils/activity/wait_event.c | 567 +------------ src/backend/utils/activity/waiteventnames.txt | 245 ++++++ src/include/Makefile | 2 +- src/include/utils/.gitignore | 1 + src/include/utils/meson.build | 18 + src/include/utils/wait_event.h | 214 +---- src/tools/msvc/Solution.pm | 18 + src/tools/msvc/clean.bat | 3 + 17 files changed, 556 insertions(+), 1572 deletions(-) 36.2% doc/src/sgml/ 52.9% src/backend/utils/activity/ 8.6% src/include/utils/ diff --git a/doc/src/sgml/.gitignore b/doc/src/sgml/.gitignore index d8e3dab338..e8cbd687d5 100644 --- a/doc/src/sgml/.gitignore +++ b/doc/src/sgml/.gitignore @@ -17,6 +17,7 @@ /errcodes-table.sgml /keywords-table.sgml /version.sgml +/waiteventnames.sgml # Assorted byproducts from building the above /postgres-full.xml /INSTALL.html diff --git a/doc/src/sgml/Makefile b/doc/src/sgml/Makefile index 71cbef230f..01a6aa8187 100644 --- a/doc/src/sgml/Makefile +++ b/doc/src/sgml/Makefile @@ -58,7 +58,7 @@ override XSLTPROCFLAGS += --stringparam pg.version '$(VERSION)' GENERATED_SGML = version.sgml \ features-supported.sgml features-unsupported.sgml errcodes-table.sgml \ - keywords-table.sgml + keywords-table.sgml waiteventnames.sgml ALLSGML := $(wildcard $(srcdir)/*.sgml $(srcdir)/ref/*.sgml) $(GENERATED_SGML) @@ -111,6 +111,9 @@ errcodes-table.sgml: $(top_srcdir)/src/backend/utils/errcodes.txt generate-errco keywords-table.sgml: $(top_srcdir)/src/include/parser/kwlist.h $(wildcard $(srcdir)/keywords/sql*.txt) generate-keywords-table.pl $(PERL) $(srcdir)/generate-keywords-table.pl $(srcdir) > $@ +waiteventnames.sgml: $(top_srcdir)/src/backend/utils/activity/waiteventnames.txt $(top_srcdir)/src/backend/utils/activity/generate-waiteventnames.pl + $(PERL) $(top_srcdir)/src/backend/utils/activity/generate-waiteventnames.pl $< > $@ + rm pgstat_wait_event.c; rm wait_event_types.h ## ## Generation of some text files. diff --git a/doc/src/sgml/filelist.sgml b/doc/src/sgml/filelist.sgml index 0d6be9a2fa..9ab235d36a 100644 --- a/doc/src/sgml/filelist.sgml +++ b/doc/src/sgml/filelist.sgml @@ -42,6 +42,7 @@ <!ENTITY maintenance SYSTEM "maintenance.sgml"> <!ENTITY manage-ag SYSTEM "manage-ag.sgml"> <!ENTITY monitoring SYSTEM "monitoring.sgml"> +<!ENTITY waiteventnames SYSTEM "waiteventnames.sgml"> <!ENTITY regress SYSTEM "regress.sgml"> <!ENTITY runtime SYSTEM "runtime.sgml"> <!ENTITY config SYSTEM "config.sgml"> diff --git a/doc/src/sgml/meson.build b/doc/src/sgml/meson.build index c6d77b5a15..53e4505b97 100644 --- a/doc/src/sgml/meson.build +++ b/doc/src/sgml/meson.build @@ -46,6 +46,16 @@ doc_generated += custom_target('errcodes-table.sgml', capture: true, ) +doc_generated += custom_target('waiteventnames.sgml', + input: files( + '../../../src/backend/utils/activity/waiteventnames.txt'), + output: 'waiteventnames.sgml', + command: [perl, files('../../../src/backend/utils/activity/generate-waiteventnames.pl'), '@INPUT@'], + build_by_default: false, + install: false, + capture: true, +) + # FIXME: this actually has further inputs, adding depfile support to # generate-keywords-table.pl is probably the best way to address that # robustly. diff --git a/doc/src/sgml/monitoring.sgml b/doc/src/sgml/monitoring.sgml index 99f7f95c39..c8648fca18 100644 --- a/doc/src/sgml/monitoring.sgml +++ b/doc/src/sgml/monitoring.sgml @@ -1100,74 +1100,7 @@ postgres 27093 0.0 0.0 30096 2752 ?
