Tests included due to intermittent failures are # removed when corresponding bug reports are closed. # # Separate the test case name and the comment with ':'. # # . : MDEV-xxxxx - # # '*' wildcard in testcase names is supported. # # To use the list, run MTR with --skip-test-list=unstable-tests option. --8<---------------cut here---------------end--------------->8--- So *all* those rests _are_ considered unstable upstream. IMHO they should be *selectively* skipped when they causes build problems in Guix, including non-deterministic frequent ones like in this case. > Watching the build on Berlin in real time, I also see that the test > output grind nearly to a halt while running those. > 'tokudb.hotindex-insert-2' took 2700439 milliseconds, or 45 minutes, if > I'm reading the test output correctly. The same is happening upstream: https://jira.mariadb.org/browse/MDEV-15198 https://jira.mariadb.org/browse/MDEV-16040 (duplicate of the above) https://jira.mariadb.org/browse/MDEV-15271 That bugs (and all others related to unstable tests) are currently unresolved.
