        "Disabled plugin is provoking Valgrind error"
        If there are any auto-alloced string plug-in options, memory is
        allocated during the call for handle_options(). We must free this
        memory if we are not installing the plug-in.

      WL#3984 (Revise locking of mysql.general_log and mysql.slow_log) · c7bbd891
      malff/marcsql@weblab.(none) authored
      Bug#25422 (Hang with log tables)
      Bug 17876 (Truncating mysql.slow_log in a SP after using cursor locks the
                thread)
      Bug 23044 (Warnings on flush of a log table)
      Bug 29129 (Resetting general_log while the GLOBAL READ LOCK is set causes
                 a deadlock)
      
      Prior to this fix, the server would hang when performing concurrent
      ALTER TABLE or TRUNCATE TABLE statements against the LOG TABLES,
      which are mysql.general_log and mysql.slow_log.
      
      The root cause traces to the following code:
      in sql_base.cc, open_table()
        if (table->in_use != thd)
        {
          /* wait_for_condition will unlock LOCK_open for us */
          wait_for_condition(thd, &LOCK_open, &COND_refresh);
        }
      The problem with this code is that the current implementation of the
      LOGGER creates 'fake' THD objects, like
      - Log_to_csv_event_handler::general_log_thd
      - Log_to_csv_event_handler::slow_log_thd
      which are not associated to a real thread running in the server,
      so that waiting for these non-existing threads to release table locks
      cause the dead lock.
      
      In general, the design of Log_to_csv_event_handler does not fit into the
      general architecture of the server, so that the concept of general_log_thd
      and slow_log_thd has to be abandoned:
      - this implementation does not work with table locking
      - it will not work with commands like SHOW PROCESSLIST
      - having the log tables always opened does not integrate well with DDL
      operations / FLUSH TABLES / SET GLOBAL READ_ONLY
      
      With this patch, the fundamental design of the LOGGER has been changed to:
      - always open and close a log table when writing a log
      - remove totally the usage of fake THD objects
      - clarify how locking of log tables is implemented in general.
      
      See WL#3984 for details related to the new locking design.
      
      Additional changes (misc bugs exposed and fixed):
      
      1)
      
      mysqldump which would ignore some tables in dump_all_tables_in_db(),
       but forget to ignore the same in dump_all_views_in_db().
      
      2)
      
      mysqldump would also issue an empty "LOCK TABLE" command when all the tables
      to lock are to be ignored (numrows == 0), instead of not issuing the query.
      
      3)
      
      Internal errors handlers could intercept errors but not warnings
      (see sql_error.cc).
      
      4)
      
      Implementing a nested call to open tables, for the performance schema tables,
      exposed an existing bug in remove_table_from_cache(), which would perform:
        in_use->some_tables_deleted=1;
      against another thread, without any consideration about thread locking.
      This call inside remove_table_from_cache() was not required anyway,
      since calling mysql_lock_abort() takes care of aborting -- cleanly -- threads
      that might hold a lock on a table.
      This line (in_use->some_tables_deleted=1) has been removed.

        "Embedded server requires mysql.plugin"
        Embedded builds should not print any error when the mysql.plugin
        table does not exist. This is achieved by checking for the existance
        of the mysql.plugin table before attempting to open it and proceed
        silently if it does not exist.

      WL#3817: Simplify string / memory area types and make things more consistent (first part) · 088e2395
      monty@mysql.com/narttu.mysql.fi authored
      The following type conversions was done:
      
      - Changed byte to uchar
      - Changed gptr to uchar*
      - Change my_string to char *
      - Change my_size_t to size_t
      - Change size_s to size_t
      
      Removed declaration of byte, gptr, my_string, my_size_t and size_s. 
      
      Following function parameter changes was done:
      - All string functions in mysys/strings was changed to use size_t
        instead of uint for string lengths.
      - All read()/write() functions changed to use size_t (including vio).
      - All protocoll functions changed to use size_t instead of uint
      - Functions that used a pointer to a string length was changed to use size_t*
      - Changed malloc(), free() and related functions from using gptr to use void *
        as this requires fewer casts in the code and is more in line with how the
        standard functions work.
      - Added extra length argument to dirname_part() to return the length of the
        created string.
      - Changed (at least) following functions to take uchar* as argument:
        - db_dump()
        - my_net_write()
        - net_write_command()
        - net_store_data()
        - DBUG_DUMP()
        - decimal2bin() & bin2decimal()
      - Changed my_compress() and my_uncompress() to use size_t. Changed one
        argument to my_uncompress() from a pointer to a value as we only return
        one value (makes function easier to use).
      - Changed type of 'pack_data' argument to packfrm() to avoid casts.
      - Changed in readfrm() and writefrom(), ha_discover and handler::discover()
        the type for argument 'frmdata' to uchar** to avoid casts.
      - Changed most Field functions to use uchar* instead of char* (reduced a lot of
        casts).
      - Changed field->val_xxx(xxx, new_ptr) to take const pointers.
      
      Other changes:
      - Removed a lot of not needed casts
      - Added a few new cast required by other changes
      - Added some cast to my_multi_malloc() arguments for safety (as string lengths
        needs to be uint, not size_t).
      - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done
        explicitely as this conflict was often hided by casting the function to
        hash_get_key).
      - Changed some buffers to memory regions to uchar* to avoid casts.
      - Changed some string lengths from uint to size_t.
      - Changed field->ptr to be uchar* instead of char*. This allowed us to
        get rid of a lot of casts.
      - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar
      - Include zlib.h in some files as we needed declaration of crc32()
      - Changed MY_FILE_ERROR to be (size_t) -1.
      - Changed many variables to hold the result of my_read() / my_write() to be
        size_t. This was needed to properly detect errors (which are
        returned as (size_t) -1).
      - Removed some very old VMS code
      - Changed packfrm()/unpackfrm() to not be depending on uint size
        (portability fix)
      - Removed windows specific code to restore cursor position as this
        causes slowdown on windows and we should not mix read() and pread()
        calls anyway as this is not thread safe. Updated function comment to
        reflect this. Changed function that depended on original behavior of
        my_pwrite() to itself restore the cursor position (one such case).
      - Added some missing checking of return value of malloc().
      - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow.
      - Changed type of table_def::m_size from my_size_t to ulong to reflect that
        m_size is the number of elements in the array, not a string/memory
        length.
      - Moved THD::max_row_length() to table.cc (as it's not depending on THD).
        Inlined max_row_length_blob() into this function.
      - More function comments
      - Fixed some compiler warnings when compiled without partitions.
      - Removed setting of LEX_STRING() arguments in declaration (portability fix).
      - Some trivial indentation/variable name changes.
      - Some trivial code simplifications:
        - Replaced some calls to alloc_root + memcpy to use
          strmake_root()/strdup_root().
        - Changed some calls from memdup() to strmake() (Safety fix)
        - Simpler loops in client-simple.c

        Move copying of global variables into thd.variables into plugin_thdvar_init().
        plugin_thdvar_init() may be called multiple times when THD::change_user() is called.
        This fixes a plugin ref-count leak when running the test mysql_client_test
