collect_mysqld_features probes mariadbd with --datadir=., which can point to the installed mysql-test tree. During this probe, mariadbd may run the datadir case-sensitivity check and try to create a *.lower-test file there. This is a bad fit when the test suite is run from a read-only installed path (e.g. /usr/share/...). Create a temporary writable datadir under $opt_vardir instead, keeping the probe on the same filesystem while avoiding writes into the installed test tree.

There was a problem hiding this comment.
Good. Now if there's feature discovery it will get the lower-case filesystem variables correctly too.

nice, glad this keeps the behavior intact. |
