      Bug#32890 Crash after repeated create and drop of tables and views · 315665cf
      unknown authored
      The problem is that CREATE VIEW statements inside prepared statements
      weren't being expanded during the prepare phase, which leads to objects
      not being allocated in the appropriate memory arenas.
      
      The solution is to perform the validation of CREATE VIEW statements
      during the prepare phase of a prepared statement. The validation
      during the prepare phase assures that transformations of the parsed
      tree will use the permanent arena of the prepared statement.

      Fix for Bug#34337: Server crash when Altering a view using · fa08b280
      unknown authored
      a table name.
        
      The problem was that fill_defined_view_parts() did not return
      an error if a table is going to be altered. That happened if
      the table was already in the table cache. In that case,
      open_table() returned non-NULL value (valid TABLE-instance from
      the cache).
        
      The fix is to ensure that an error is thrown even if the table
      is in the cache.

      Bug#32265 Server returns different metadata if prepared statement is used · a399fefd
      unknown authored
      Executing a prepared statement associated with a materialized
      cursor yields to the client a metadata packet with wrong table
      and database names. The problem was occurring because the server
      was sending the the name of the temporary table used by the cursor
      instead of the table name of the original table. The same problem
      occurs when selecting from views, in which case the table name was
      being sent and not the name of the view.
        
      The solution is to fill the list item from the temporary table but
      preserving the table and database names of the original fields. This
      is achieved by tweaking the Select_materialize to accept a pointer to
      the Materialized_cursor class which contains the item list to be filled.
      
      
      sql/sql_cursor.cc:
        Fill the item list in the send_fields method and preserve
        the table and database name of the fields.

      Bug#33798 prepared statements improperly handle large unsigned ints · 7d98c21c
      unknown authored
      The unsignedness of large integer user variables was not being
      properly preserved when feeded to prepared statements. This was
      happening because the unsigned flags wasn't being updated when
      converting the user variable is converted to a parameter.
      
      The solution is to copy the unsigned flag when converting the
      user variable to a parameter and take the unsigned flag into
      account when converting the integer to a string.

      Bug #34305 show slave status handling segfaults when slave io is about · 3b6a71a4
      unknown authored
          to leave
      
      The artifact was caused by
      a flaw in concurrent accessing the slave's io thd by
      the io itself and a handling show slave status thread.
      Namely, show_master_info did not acquire mi->run_lock mutex that is
      specified for mi->io_thd member.
      
      Fixed with deploying the mutex locking and unlocking. The mutex is kept
      short time and without interleaving with mi->data_lock mutex.
      
      Todo: to report and fix an issue with 
          sys_var_slave_skip_counter::{methods} 
      seem to acquire incorrectly
           active_mi->rli.run_lock
      instead of the specified
           active_mi->rli.data_lock
      
      A test case is difficult to compose, so rpl_packet should continue serving
      as the indicator.
      
      
      sql/slave.cc:
        implementing a TODO left at 4.1 time:
        mending access to mi->io_thd with the specified mutex;
      sql/slave.h:
        adding a member name to the list of that run_lock guards.

      BUG#26489 Corruption in relay logs · 5a039fa2
      unknown authored
      Here is the scenario that causes the failure.(by Mats)
      
      1. The to-be corrupt log event (let's call it X), is split into two
         packets B and C on the network level (net_write_buff()). The parts
         are X = (x',x''). The part x' ends up in packet B and part x''
         ends up in packet C. Prior to the corrupt event X, the event Y has
         been written successfully, but has been split into two packets as
         well, which we call (y',y'').
      2. The master sends packet A = (y'',x') to the slave, increases the
         packet sequence number, the slave receives the packet, but fails
         to reply before the master gets a timeout.
      3. Since the master got a timeout, it reports failure, and aborts
         sending the binary log by exiting mysql_binlog_send(). However, it
         leaves the buffer intact, still holding y'' (but not x', since the
         write_pos is not increased).
      4. After exiting mysql_binlog_send(), the master does a
         disconnection of the client thread, which involves sending an
         error message e to the client (i.e., the slave).
      5. In this case, net_write_buff() is used again, but this time the
         old contents of the packet is used so that the new packet is
         D = (y'',e). Note that this will use a new packet sequence number,
         since the packet number was increased in step 2.
      6. The slave receives the tail y'' of the Y log event, concatenates
         this with x' (which it already received), and writes the event
         (x',y'') it to the relay log since it hasn't noticed anything is
         amiss.
      7. It then tries to read more bytes, which is either e (if the length
         given for X just happened to match the length given for Y, or just
         plain garbage because the slave is out of sync with what is
         actually sent.
      8. After a while, the SQL thread tries to execute the event (x',y''),
         which is very likely to be just nonsense.
      
      The problem can be fixed by not resetting net->error after the call of 
      mysql_binlog_send, so the error message will not be sent and the connection
      will be closed.
      
      
      sql/sql_parse.cc:
        Do not reset net->error, if net->error == 2, we should not try to use the connection again

      Bug#33618 (Crash in sp_rcontext) · e6a077e3
      unknown authored
      Bug 33983 (Stored Procedures: wrong end <label> syntax is accepted)
      
      The server used to crash when REPEAT or another control instruction
      was used in conjunction with labels and a LEAVE instruction.
      
      The crash was caused by a missing "pop" of handlers or cursors in the
      code representing the stored program. When executing the code in a loop,
      this missing "pop" would result in a stack overflow, corrupting memory.
      
      Code generation has been fixed to produce the missing h_pop/c_pop
      instructions.
      
      Also, the logic checking that labels at the beginning and the end of a
      statement are matched was incorrect, causing Bug 33983.
      End labels, when used, must match the label used at the beginning of a block.

      Bug#25347: mysqlcheck -A -r doesn't repair table marked as crashed
      
      mysqlcheck tests nullness of the engine type to know whether the
      "table" is a view or not.  That also falsely catches tables that 
      are severly damaged.
      
      Instead, use SHOW FULL TABLES to test whether a "table" is a view
      or not.
      
      (Don't add new function.  Instead, get original data a smarter way.)
      
      Make it safe for use against databases before when views appeared.
      
      
      client/mysqlcheck.c:
        Use SHOW FULL TABLES to test better whether a name in the table
        list is one of a view.  Checking that the engine is NULL is 
        insufficient.
        
        Implemented suggestion from jimw that involved removing most of 
        original patch and getting data a better way
      mysql-test/r/mysqlcheck.result:
        Verify that tables that have NULL/unreadable engine types are 
        processed and not interpreted as views.
