ha_innobase::open() should not acquire dict_sys.latch twice

    XMLWordPrintable

Details

    Description

      The following stack trace had to wait on dict_sys.latch:

      ssux_lock_impl<false>::rd_wait()
      		 
      dict_table_open_on_name(char const*, bool, dict_err_ignore_t)
      		 
      dict_stats_update(dict_table_t*, dict_stats_upd_option_t)
      		 
      ha_innobase::info_low(unsigned int, bool)
      		 
      ha_innobase::open(char const*, int, unsigned int)
      		 
      handler::ha_open(TABLE*, char const*, int, unsigned int, st_mem_root*, List<String>*)

      (According to Marko Mäkelä: ) This one is an InnoDB bug. We certainly should not acquire and release a shared dict_sys.latch within a single ha_innobase::open().
