Problem was that we could take page latches on different order than wat is entitled with SX-lock. To follow the latching order defined in WL#6326, acquire index->lock X-latch. This entitles us to acquire page latches in any order for the index. btr0btr.cc Document latch rules before and after MariaDB 10.2.2 sync0rw.cc Document latch compatibility rules better. btr_defragment_merge_pages Fix parameter value. btr_defragment_thread Acquire X-lock to dict_index_t::lock before restoring cursor position and continuing defragmentation. ha_innobase::optimize Restore defragment feature. Testing Add GIS-index and FT-index to table being defragmented. Defragmentation is not done to GIS-indexes and FT auxiliary tables. |
