      * Fixed bug [MDEV-6071](https://jira.mariadb.org/browse/MDEV-6071). The method JOIN\_CACHE::init may fail (return 1) if some conditions on the used join buffer is not satisfied. For example it fails if join\_buffer\_size is greater than join\_buffer\_space\_limit. The conditions should be checked when running the EXPLAIN command for the query. That's why the method JOIN\_CACHE::init has to be called for EXPLAIN commands as well.
