From 6cea447e6a10cd7ef511470e809a894a013e6a18 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Fri, 16 Jul 2021 13:21:18 +0900 Subject: [PATCH] Disable tests involving ZLIB on Windows for pg_receivewal As reported by buildfarm member bowerbird, those tests are unstable on Windows. The failure produced there points to a problem with gzflush(), that fails to sync a file freshly-opened, with a gzFile properly opened. While testing this myself with MSVC, I bumped into a different error where a file could simply not be opened, so this makes me rather doubtful that testing this area on Windows is a good idea if this finishes with random concurrency failures. This requires more investigation, and keeping this buildfarm member red is not a good thing in the long-term, so for now this just disables this set of tests on Windows.
