Extracting cross-version-upgrade knowledge from buildfarm client - Mailing list pgsql-hackers (2024)

Home>mailing lists

This is a followup to the discussion at [1], in which we agreed thatit's time to fix the buildfarm client so that knowledge aboutcross-version discrepancies in pg_dump output can be moved intothe community git tree, making it feasible for people other thanAndrew to fix problems when we change things of that sort.The idea is to create helper files that live in the git tree andare used by the BF client to perform the activities that are likelyto need tweaking.Attached are two patches, one for PG git and one for the buildfarmclient, that create a working POC for this approach. I've onlycarried this as far as making a helper file for HEAD, but I believethat helper files for the back branches would mostly just need tobe cut-down versions of this one. I've tested it successfully withcross-version upgrade tests down to 9.3. (9.2 would need some morework, and I'm not sure if it's worth the trouble --- are we going toretire 9.2 soon?)I'm a very mediocre Perl programmer, so I'm sure there are stylisticand other problems, but I'm encouraged that this seems feasible.Also, I wonder if we can't get rid ofsrc/bin/pg_upgrade/upgrade_adapt.sql in favor of using this code.I tried to write adjust_database_contents() in such a way that itcould be pointed at a database by some other Perl code that'snot the buildfarm client. regards, tom lane[1] https://www.postgresql.org/message-id/951602.1673535249%40sss.pgh.pa.usdiff --git a/src/test/perl/PostgreSQL/Test/AdjustUpgrade.pm b/src/test/perl/PostgreSQL/Test/AdjustUpgrade.pmnew file mode 100644index 0000000000..279b2bd0e6--- /dev/null+++ b/src/test/perl/PostgreSQL/Test/AdjustUpgrade.pm@@ -0,0 +1,421 @@++# Copyright (c) 2023, PostgreSQL Global Development Group++=pod++=head1 NAME++PostgreSQL::Test::AdjustUpgrade - helper module for cross-version upgrade tests++=head1 SYNOPSIS++ use PostgreSQL::Test::AdjustUpgrade;++ # Adjust contents of old-version database before dumping+ adjust_database_contents($old_version, $psql, %dbnames);++ # Adjust contents of old pg_dumpall output file to match newer version+ $dump = adjust_old_dumpfile($old_version, $dump);++ # Adjust contents of new pg_dumpall output file to match older version+ $dump = adjust_new_dumpfile($old_version, $dump);++=head1 DESCRIPTION++C<PostgreSQL::Test::AdjustUpgrade> encapsulates various hacks needed to+compare the results of cross-version upgrade tests.++=cut++package PostgreSQL::Test::AdjustUpgrade;++use strict;+use warnings;++use Exporter 'import';++our @EXPORT = qw(+ adjust_database_contents+ adjust_old_dumpfile+ adjust_new_dumpfile+);++=pod++=head1 ROUTINES++=over++=item adjust_database_contents($old_version, $psql, %dbnames)++Perform any DDL operations against the old-version installation that are+needed before we can pg_upgrade it into the current PostgreSQL version.++Typically this involves dropping or adjusting no-longer-supported objects.++Arguments:++=over++=item C<old_version>: Branch we are upgrading from, e.g. 'REL_11_STABLE'++=item C<psql>: Object with a method C<old_psql($dbname, $sql_command)>+to perform SQL against the old installation, returning psql's exit status++=item C<dbnames>: Hash of database names present in the old installation++=back++=cut++sub adjust_database_contents+{+ my ($old_version, $psql, %dbnames) = @_;++ # nothing to do for non-cross-version tests+ return if $old_version eq 'HEAD';++ # stuff not supported from release 16+ if ( $old_version ge 'REL_12_STABLE'+ and $old_version lt 'REL_16_STABLE')+ {+ # Can't upgrade acl*tem in user tables from pre 16 to 16+.+ # Also can't handle child tables with locally-generated columns.+ my $prstmt = join(';',+ 'alter table public.tab_core_types drop column acl*tem',+ 'drop table public.gtest_normal_child',+ 'drop table public.gtest_normal_child2');++ $psql->old_psql("regression", $prstmt);+ return if $?;+ }++ # stuff not supported from release 14+ if ($old_version lt 'REL_14_STABLE')+ {+ # postfix operators (some don't exist in very old versions)+ my $prstmt = join(';',+ 'drop operator #@# (bigint,NONE)',+ 'drop operator #%# (bigint,NONE)',+ 'drop operator if exists !=- (bigint,NONE)',+ 'drop operator if exists #@%# (bigint,NONE)');++ $psql->old_psql("regression", $prstmt);+ return if $?;++ # get rid of dblink's dependencies on regress.so+ $prstmt = join(';',+ 'drop function if exists public.putenv(text)',+ 'drop function if exists public.wait_pid(integer)');++ my $regrdb =+ $old_version le "REL9_4_STABLE"+ ?
