      Bug#29898: Item_date_typecast::val_int doesn't reset the null_value flag. · a131428f
      unknown authored
      The Item_date_typecast::val_int function doesn't reset null_value flag.
      This makes all values that follows the first null value to be treated as nulls
      and led to a wrong result.
      
      Now the Item_date_typecast::val_int function correctly sets the null_value flag
      for both null and non-null values.

      Bug#29850: Wrong charset of GROUP_CONCAT result when the select employs · 7f6a8164

      a temporary table.
      
      The result string of the Item_func_group_concat wasn't initialized in the 
      copying constructor of the Item_func_group_concat class. This led to a
      wrong charset of GROUP_CONCAT result when the select employs a temporary
      table.
      
      The copying constructor of the Item_func_group_concat class now correctly
      initializes the charset of the result string.

      A fix for Bug#29431 killing an insert delayed thread causes crash · e81e55e7
      unknown authored
      No test case, since the bug requires a stress case with 30 INSERT DELAYED
      threads and 1 killer thread to repeat. The patch is verified
      manually.
      Review fixes.
      
      The server that is running DELAYED inserts would deadlock itself
      or crash under high load if some of the delayed threads were KILLed
      in the meanwhile.
      
      The fix is to change internal lock acquisition order of delayed inserts
      subsystem and to ensure that
      Delayed_insert::table_list::db does not point to volatile memory in some 
      cases.
      For details, please see a comment for sql_insert.cc.
      
      
      sql/sql_insert.cc:
        A fix for Bug#29431 killing an insert delayed thread causes crash
        
        1) The deadlock was caused by different lock acquisition order
        between delayed_get_table and handle_delayed_insert.
        
        delayed_get_table would:
        - acquire LOCK_delayed_create
        - create a new Delayed_insert instance
        - acquire instance mutex (di->mutex)
        - "lock the instance in memory" by 
        increasing di->locked_in_memory variable
        - start the delayed thread
        - release di->mutex
        - let the delayed thread open the delayed table
        - discover that the delayed thread was killed
        - try to unlock() the delayed insert instance in memory
        - in Delayed_insert::unlock() do
         * lock LOCK_delayed_insert
         * decrease locks_in_memory and discover it's 0
         * attempt to lock di->mutex to broadcast di->cond condition <-- deadlock
         here
        
        Meanwhile, the delayed thread would
         * lock di->mutex
         * open the table
         * get killed
         * not notice that and attempt to lock LOCK_delayed_insert
        to register itself in the delayed insert list <-- deadlock here.
        
        Simply put, delayed_get_table used to lock LOCK_delayed_insert and then 
        di->mutex, and handle_delayed_insert would lock di->mutex and then 
        LOCK_delayed_insert.
        
        Fixed by moving registration in the list of delayed insert threads from 
        handle_delayed_insert to delayed_get_table - so that now
        handle_delayed_insert doesn't need to acquire LOCK_delayed_insert mutex.
        
        
        2) di->table_list.db was copied by-pointer from table_list.db of the first
        producer -- the one who initiated creation of the delayed insert thread.
        This producer might be long gone when the member is needed
        (handle_delayed_insert:open_ltable),
        e.g. by having been killed with KILL CONNECTION statement.
        Fixed by using a pointer to the consumer's deep copy of THD::db.
        
        3) In find_handler, we shouldn't assume that Delayed_insert object
        already (or still) has a table opened all the time it is
        present in the delayed insert list. E.g. it's not the case
        when Delayed_insert decided to terminate, closed the table, but haven't
        yet unregistered from the list (see the end of handle_delayed_insert).

      Fixed bug #28524. · 2bfe84d4
      unknown authored
      For each view the mysqldump utility creates a temporary table
      with the same name and the same columns as the view 
      in order to satisfy views that depend on this view.
      After the creation of all tables, mysqldump drops all
      temporary tables and creates actual views.
      However, --skip-add-drop-table and --compact flags disable
      DROP TABLE statements for those temporary tables. Thus, it was
      impossible to create the views because of existence of the
      temporary tables with the same names.
      
      
      client/mysqldump.c:
        Fixed bug #28524.
        The mysqldump utility has been modified to unconditionally drop
        temporary tables before the creation of views.
