DB_TRX_ID is not actually being reset when the history is removed

    XMLWordPrintable

Details

    Description

      The purpose of MDEV-12288 is to reset the DB_TRX_ID column when the history is being removed. This is not taking place:

      --source include/have_innodb.inc
      		 
      CREATE TABLE t1(a INT PRIMARY KEY, b INT NOT NULL) ENGINE=InnoDB;
      		 
      INSERT INTO t1 VALUES(1,2),(3,4);
      		 
      UPDATE t1 SET b=-3 WHERE a=3;
      		 
      # Initiate a full purge, which should reset all DB_TRX_ID.
      		 
      SET GLOBAL innodb_fast_shutdown=0;
      		 
      --source include/shutdown_mysqld.inc

      After running this test, the t1.ibd file page 3 will contain nonzero DB_TRX_ID values.
