Marko Mäkelä	3e38d15585	MDEV-21509 Possible hang during purge of history, or rollback ... WL#6326 in MariaDB 10.2.2 introduced a potential hang on purge or rollback when an index tree is being shrunk by multiple levels. This fix is based on mysql/mysql-server@f2c5852630 with the main difference that our version of the test case uses DEBUG_SYNC instrumentation on ROLLBACK, not on purge. btr_cur_will_modify_tree(): Simplify the check further. This is the actual bug fix. row_undo_mod_remove_clust_low(), row_undo_mod_clust(): Add DEBUG_SYNC instrumentation for the test case.	2020-01-17 14:27:28 +02:00
