I made a patch, please review and push if you think that's OK, I will otherwise push it myself after some time. The patch produces some test error, not sure if deterministic, looks related to networking disabled in build sandboxes, log: The servers were restarted 778 times Spent 6689.041 of 234 seconds executing testcases Failure: Failed 1/2711 tests, 99.96% were successful. Failing test(s): main.system_mysql_db The log files in var/log may give you some hint of what went wrong. If you want to report this error, please read first the documentation at http://dev.mysql.com/doc/mysql/en/mysql-test-suite.html 969 tests were skipped, 161 by the test itself. mysql-test-run: *** ERROR: there were failing test cases Error happened at lib/mtr_report.pm line 687. mtr_report::mtr_error("there were failing test cases") called at lib/mtr_report.pm line 556 mtr_report::mtr_report_stats("Failure", 1, ARRAY(0x19d75d0), ARRAY(0x1420d08)) called at /tmp/guix-build-mariadb-10.5.9.drv-0/mariadb-10.5.9/mysql-test/mysql-test-run.pl line 586 main::main() called at /tmp/guix-build-mariadb-10.5.9.drv-0/mariadb-10.5.9/mysql-test/mysql-test-run.pl line 387 command "./mtr" "--verbose" "--retry=3" "--testcase-timeout=40" "--suite-timeout=600" "--parallel" "48" "--skip-rpl" "--skip-test-list=unstable-tests" failed with status 1 builder for `/gnu/store/hk1awalxmnd7a7qz4v8r5h7bpxc4ig5b-mariadb-10.5.9.drv' failed with exit code 1 @ build-failed /gnu/store/hk1awalxmnd7a7qz4v8r5h7bpxc4ig5b-mariadb-10.5.9.drv - 1 builder for `/gnu/store/hk1awalxmnd7a7qz4v8r5h7bpxc4ig5b-mariadb-10.5.9.drv' failed with exit code 1 derivation '/gnu/store/hk1awalxmnd7a7qz4v8r5h7bpxc4ig5b-mariadb-10.5.9.drv' offloaded to 'www.proxmox-2.schmilblick.org' failed: build of `/gnu/store/hk1awalxmnd7a7qz4v8r5h7bpxc4ig5b-mariadb-10.5.9.drv' failed build of /gnu/store/hk1awalxmnd7a7qz4v8r5h7bpxc4ig5b-mariadb-10.5.9.drv failed View build log at '/var/log/guix/drvs/hk/1awalxmnd7a7qz4v8r5h7bpxc4ig5b-mariadb-10.5.9.drv.bz2'. guix build: error: build of `/gnu/store/hk1awalxmnd7a7qz4v8r5h7bpxc4ig5b-mariadb-10.5.9.drv' failed Léo Le Bouter (1): gnu: mariadb: Update to 10.5.9 [fixes CVE-2021-27928]. gnu/packages/databases.scm | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) -- 2.31.0
