Details

    Description

      I notice that builds of MariaDB 10.6.7 in Debian was failing due to multiple reasons. One failure not reported before was main.func_json_notembedded on arch mipsel/s390x/powerpc:

      main.func_json_notembedded               w3 [ fail ]
      		 
              Test ended at 2022-02-25 14:49:46
      		 
       
      		 
      CURRENT_TEST: main.func_json_notembedded
      		 
      mysqltest: At line 12: query 'set @obj=concat_ws('','{', repeat('"a":"b",', 125000000/2), '"c":"d"}')' failed: <Unknown> (5): Out of memory (Needed 500000016 bytes)
      		 
       
      		 
      The result from queries just before the failure was:
      		 
      set global max_allowed_packet=1073741824;
      		 
      connect u,localhost,root;
      		 
      #
      		 
      # MDEV-24909 JSON functions don't respect KILL QUERY / max_statement_time limit
      		 
      #
      		 
      set group_concat_max_len= 4294967295;
      		 
      set @obj=concat_ws('','{', repeat('"a":"b",', 125000000/2), '"c":"d"}');
