On 10.0, the assertion failure doesn't happen, but there is some uncleanness on the shutdown still (e.g. seen with valgrind), so I suppose it might be affected also, thus filing both for 5.5 and 10.0.
# It's not necessary to install TokuDB at runtime,
|
# instead the server can be run with --plugin-load=ha_tokudb
|
|
INSTALL SONAME 'ha_tokudb';
|
DROP TABLE IF EXISTS t1;
|
CREATE TABLE t1 (a INT) ENGINE=TokuDB;
|
INSERT INTO t1 VALUES (1),(2);
|
UNINSTALL SONAME 'ha_tokudb';
|
|
# Let server to shutdown (with MTR, it happens on its own)
