Re: [Maria-developers] 1e9ea675a18: MDEV-21282 Assertion 'mariadb_table' failed in gcol.innodb_virtual_debug_purge

Hi, Thirunarayanan! Sure, it's purely InnoDB functionality. If you say that purge thread already hold MDL for the table, then open_purge_table() doesn't need to. Ok to push as you see fit. On Jun 03, Thirunarayanan Balathandayuthapani wrote:

- commit ea37b144094a0c2ebfc6774047fd473c1b2a8658 (MDEV-16678) caused a regression. when purge thread tries to open the table for virtual column computation, there is no need to acquire MDL for the table. Because purge thread already hold MDL for the table
