ER_KEY_NOT_FOUND upon online COPY ALTER on a partitioned table

Details

    Description

      It appears that the "online" alter gets confused when concurrent DML moves rows between partitions.

      --source include/have_partition.inc
      		 
      --source include/have_debug_sync.inc
      		 
       
      		 
      create table t (a int) partition by hash(a) partitions 2;
      		 
      insert into t values (1),(3);
      		 
      set debug_sync= 'alter_table_online_progress WAIT_FOR goforit';
      		 
      --send
      		 
        alter table t force, algorithm=copy, lock=none;
      		 
       
      		 
      --connect (con1,localhost,root,,)
      		 
      update t set a = a + 1;
      		 
      set debug_sync= 'now SIGNAL goforit';
      		 
       
      		 
      --connection default
      		 
      --reap
      		 
       
      		 
      select * from t;
      		 
       
      		 
      # Cleanup
      		 
      set debug_sync= RESET;
      		 
      drop table t;
