From 33aa012f262e33526d44f1c5832550098158bcbe Mon Sep 17 00:00:00 2001 From: =?utf8?q?Otto=20Kek=C3=A4l=C3=A4inen?= Date: Thu, 7 Aug 2025 21:30:51 -0700 Subject: [PATCH] Suppress native AIO warning introduced in 10.8.3 Upstream a87bb96 introduced a new warning, visible at least on all ppc64el and s390x builds which makes the post-build mariadb-test-test fail: [Warning] InnoDB: native AIO failed: falling back to innodb_use_native_aio=OFF The case of this is the ci environment only where there is insufficent fs.aio-max-nr configured. A such we are adding a suppression to the mtr only. The warning is valuable for users. Upstream MDEV-37411 has added a io_setup as a warning, which will fail in the CI environment, so we're pre-emptively suppressing this warning too. Unlike upstream MariaDB, in Debian we removed libaio in for Linux on MariaDB 10.6+ in 612630c6 and completely in 1d648d6f. This was re-added by upstream added a system variable innodb_linux_aio to control, and also provided automated fallback. As such we're readding it back too. With liburing still seccomp filterer in container environments having a libaio fallback is more valuable than the threads implementation of last resort. Edited & Updated: Daniel Black Forwarded: https://jira.mariadb.org/browse/MDEV-37411 (rejected) Upstream rejected this with the conclusion, is that it will start working in Debian/Salsa/Ubuntu/Launchpad once the Linux kernel is new enough to handle the I/O calls and fallbacks properly, or once the CI system increases the value of /proc/sys/fs/aio-max-nr to 1 million or so, to allow multiple parallel MariaDB servers (as started by mariadb-test-run) each have enough quota for native AIO to work.
