Subject: pgsql: Stabilize xid_wraparound/t/002_limits.pl test.
Date: Wed, 02 Sep 2026 14:53:42 +0000
Message-ID: <E1x1mLN-00000003BwR-0jtd@gemulon.postgresql.org> (raw)
Stabilize xid_wraparound/t/002_limits.pl test.
Not many buildfarm members run this test, since it's gated behind
PG_TEST_EXTRA=xid_wraparound, but of those that do, the slower ones
not infrequently fail. The reason seems to be that the test expects
an INSERT command to either succeed or fail, but there's a window
where it can succeed while issuing a warning about impending
wraparound. poll_query_until treats nonempty stderr as a failure,
so it loops an extra time until the INSERT succeeds with no warning.
There seems no reason to treat this behavior as wrong, so adjust
the test to accept it.
