      Bug#23771 AFTER UPDATE trigger not invoked when there are no changes of the data · 8d51c6ad
      unknown authored
      The problem is that AFTER UPDATE triggers will fire only if the
      new data is different from the old data on the row. The trigger
      should fire regardless of whether there are changes to the data.
      
      The solution is to fire the trigger on UPDATE even if there are
      no changes to the value (because the value is the same).

        the trigger will fire even if the records are the same.

      called from a SELECT doesn't cause ROLLBACK of state"
      Make private all class handler methods (PSEA API) that may modify
      data. Introduce and deploy public ha_* wrappers for these methods in 
      all sql/.
      This necessary to keep track of all data modifications in sql/,
      which is in turn necessary to be able to optimize two-phase
      commit of those transactions that do not modify data.
      
      
      sql/ha_partition.cc:
        Class ha_partition is no longer a friend of class handler.
        Use the public handler interface (handler::ha_ methods) for partition
        operations.
        Remove unnecessary casts from char[] to const char *.ppзи выафвыаafa
      sql/handler.cc:
        Function ha_create_table() is no longer a friend of class handler.
        Use public handler::change_table_ptr() to access private members.
        This fixes a subtle bug (no test case in the test suite) when a
        deletion error occurs inside one partition of a partitioned engine. 
        The old code would crash in handler::print_error() in this case.
        
        Implement the newly introduced public ha_* wrappers of the private
        virtual handler methods.
      sql/handler.h:
        Introduce ha_* wrappers to all class handler methods that may
        modify data. This is necessary to be able to keep track of
        data modifying operations of class handler and optimize read-only
        transactions.
      sql/item_sum.cc:
        delete_all_rows -> ha_delete_all_rows
      sql/sql_base.cc:
        Use the new public wrappers.
      sql/sql_delete.cc:
        delete_all_rows -> ha_delete_all_rows
      sql/sql_partition.cc:
        Use the new public wrappers.
      sql/sql_select.cc:
        delete_all_rows -> ha_delete_all_rows
        delete_table -> ha_delete_table
        disabe_indexes -> ha_disable_idnexes
      sql/sql_show.cc:
        delete_all_rows -> ha_delete_all_rows
      sql/sql_table.cc:
        Use the public wrappers for class handler DDL methods.
        All methods which may change handler data are now accessed via a public
        wrapper.
      sql/sql_union.cc:
        delete_all_rows -> ha_delete_all_rows

      Bug#12713 "Error in a stored function called from a SELECT doesn't · 2a0d2fef
      unknown authored
      cause ROLLBACK of statement", part 1. Review fixes.
      
      Do not send OK/EOF packets to the client until we reached the end of 
      the current statement.
      This is a consolidation, to keep the functionality that is shared by all 
      SQL statements in one place in the server.
      Currently this functionality includes:
      - close_thread_tables()
      - log_slow_statement().
      
      After this patch and the subsequent patch for Bug#12713, it shall also include:
      - ha_autocommit_or_rollback()
      - net_end_statement()
      - query_cache_end_of_result().
      
      In future it may also include:
      - mysql_reset_thd_for_next_command().
      
      
      include/mysql_com.h:
        Rename now unused members of NET: no_send_ok, no_send_error, report_error.
        These were server-specific variables related to the client/server
        protocol. They have been made obsolete by this patch.
        
        Previously the same members of NET were used to store the error message
        both on the client and on the server. 
        The error message was stored in net.last_error (client: mysql->net.last_error,
        server: thd->net.last_error).
        The error code was stored in net.last_errno (client: mysql->net.last_errno,
        server: thd->net.last_errno).
        The server error code and message are now stored elsewhere 
        (in the Diagnostics_area), thus NET members are no longer used by the
        server.
        Rename last_error to client_last_error, last_errno to client_last_errno
        to avoid potential bugs introduced by merges.
      include/mysql_h.ic:
        Update the ABI file to reflect a rename. 
        Renames do not break the binary compatibility.
      libmysql/libmysql.c:
        Rename last_error to client_last_error, last_errno to client_last_errno.
        This is necessary to ensure no unnoticed bugs introduced by merged
        changesets.
        
        Remove net.report_error, net.no_send_ok, net.no_send_error.
      libmysql/manager.c:
        Rename net.last_errno to net.client_last_errno.
      libmysqld/lib_sql.cc:
        Rename net.last_errno to net.client_last_errno.
        
        Update the embedded implementation of the client-server protocol to
        reflect the refactoring of protocol.cc.
      libmysqld/libmysqld.c:
        Rename net.last_errno to net.client_last_errno.
      mysql-test/r/events.result:
        Update to reflect the change in mysql_rm_db(). Now we drop stored
        routines and events for a given database name only if there
        is a directory for this database name. ha_drop_database() and
        query_cache_invalidate() are called likewise. 
        Previously we would attempt to drop routines/events even if database
        directory was not found (it worked, since routines and events are stored
        in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc
        does not exist".
        The change was done because the previous code used to call send_ok()
        twice, which led to an assertion failure when asserts against it were
        added by this patch.
      mysql-test/r/grant.result:
        Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error 
        if mysql.procs_priv is missing.
        This fixes the assert that send_ok() must not called after send_error()
        (the original patch for Bug 16470 was prone to this).
      mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result:
        Produce a more detailed error message.
      mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result:
        Produce a more detailed error message.
      mysql-test/t/grant.test:
        Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv
        is missing.
      server-tools/instance-manager/mysql_connection.cc:
        Rename net.last_errno to net.client_last_errno.
      sql/ha_ndbcluster_binlog.cc:
        Add asserts. 
        
        Use getters to access statement status information.
        
        Add a comment why run_query() is broken. Reset the diagnostics area
        in the end of run_query() to fulfill the invariant that the diagnostics_area
        is never assigned twice per statement (see the comment in the code
        when this can happen). We still do not clear thd->is_fatal_error and
        thd->is_slave_error, which may lead to bugs, I consider the whole affair
        as something to be dealt with separately.
      sql/ha_partition.cc:
        fatal_error() doesn't set an error by itself. Perhaps we should
        remove this method altogether and instead add a flag to my_error 
        to set thd->is_fatal_error property.
        
        Meanwhile, this change is a part of inspection made to the entire source
        code with the goal to ensure that fatal_error()
        is always accompanied by my_error().
      sql/item_func.cc:
        There is no net.last_error anymore. Remove the obsolete assignment.
      sql/log_event.cc:
        Use getters to access statement error status information.
      sql/log_event_old.cc:
        Use getters to access statement error status information.
      sql/mysqld.cc:
        Previously, if a continue handler for an error was found, my_message_sql() 
        would not set an error in THD. Since the current statement
        must be aborted in any case, find_handler() had a hack to assign 
        thd->net.report_error to 1.
        
        Remove this hack. Set an error in my_message_sql() even if the continue
        handler is found. The error will be cleared anyway when the handler
        is executed. This is one action among many in this patch to ensure the 
        invariant that whenever thd->is_error() is TRUE, we have a message in 
        thd->main_da.message().
      sql/net_serv.cc:
        Use a full-blown my_error() in net_serv.cc to report an error,
        instead of just setting net->last_errno. This ensures the invariant that
        whenever thd->is_error() returns TRUE, we have a message in 
        thd->main_da.message().
        
        Remove initialization of removed NET members.
      sql/opt_range.cc:
        Use my_error() instead of just raising thd->net.report_error. 
        This ensures the invariant that whenever thd->is_error() returns TRUE, 
        there is a message in thd->main_da.message().
      sql/opt_sum.cc:
        Move invocation of fatal_error() right next to the place where
        we set the error message. That makes it easier to track that whenever
        fatal_error() is called, there is a message in THD.
      sql/protocol.cc:
        Rename send_ok() and send_eof() to net_send_ok() and net_send_eof() 
        respectively. These functions write directly to the network and are not 
        for use anywhere outside the client/server protocol code. 
        
        Remove the code that was responsible for cases when either there is 
        no error code, or no error message, or both.
        Instead the calling code ensures that they are always present. Asserts
        are added to enforce the invariant.
        
        Instead of a direct access to thd->server_status and thd->total_warn_count
        use function parameters, since these from now on don't always come directly
        from THD.
        
        Introduce net_end_statement(), the single-entry-point replacement API for 
        send_ok(), send_eof() and net_send_error().
        
        Implement Protocol::end_partial_result_set to use in select_send::abort()
        when there is a continue handler.
      sql/protocol.h:
        Update declarations.
      sql/repl_failsafe.cc:
        Use getters to access statement status information in THD.
        Rename net.last_error to net.client_last_error.
      sql/rpl_record.cc:
        Set an error message in prepare_record() if there is no default
        value for the field -- later we do print this message to the client.
      sql/rpl_rli.cc:
        Use getters to access statement status information in THD.
      sql/slave.cc:
        In create_table_from_dump() (a common function that is used in 
        LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks
        with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded.
        
        Update has_temporary_error() to work correctly when no error is set.
        This is the case when Incident_log_event is executed: it always returns
        an error but does not set an error message.
        
        Use getters to access error status information.
      sql/sp_head.cc:
        Instead of hacks with no_send_error, work through the diagnostics area 
        interface to suppress sending of OK/ERROR packets to the client.
        
        Move query_cache_end_of_result before log_slow_statement(), similarly
        to how it's done in dispatch_command().
      sql/sp_rcontext.cc:
        Remove hacks with assignment of thd->net.report_error, they are not
        necessary any more (see the changes in mysqld.cc).
      sql/sql_acl.cc:
        Use getters to access error status information in THD.
      sql/sql_base.cc:
        Access thd->main_da.sql_errno() only if there is an error. This fixes
        a bug when auto-discovery, that was effectively disabled under pre-locking.
      sql/sql_binlog.cc:
        Remove hacks with no_send_ok/no_send_error, they are not necessary 
        anymore: the caller is responsible for network communication.
      sql/sql_cache.cc:
        Disable sending of OK/ERROR/EOF packet in the end of dispatch_command
        if the response has been served from the query cache. This raises the 
        question whether we should store EOF packet in the query cache at all,
        or generate it anew for each statement (we should generate it anew), but
        this is to be addressed separately.
      sql/sql_class.cc:
        Implement class Diagnostics_area. Please see comments in sql_class.h
        for details.
        
        Fix a subtle coding mistake in select_send::send_data: when on slave, 
        an error in Item::send() was ignored.
        The problem became visible due to asserts that the diagnostics area is
        never double assigned.
        
        Remove initialization of removed NET members.
        
        In select_send::abort() do not call select_send::send_eof(). This is
        not inheritance-safe. Even if a stored procedure continue handler is
        found, the current statement is aborted, not succeeded.
        Instead introduce a Protocol API to send the required response, 
        Protocol::end_partial_result_set().
        
        This simplifies implementation of select_send::send_eof(). No need
        to add more asserts that there is no error, there is an assert inside
        Diagnostics_area::set_ok_status() already.
        
        Leave no trace of no_send_* in the code.
      sql/sql_class.h:
        Declare class Diagnostics_area. 
        
        Remove the hack with no_send_ok from
        Substatement_state.
        
        Provide inline implementations of send_ok/send_eof.
        
        Add commetns.
      sql/sql_connect.cc:
        Remove hacks with no_send_error. 
        
        Since now an error in THD is always set if net->error, it's not necessary
        to check both net->error and thd->is_error() in the do_command loop.
        
        Use thd->main_da.message() instead of net->last_errno.
        
        Remove the hack with is_slave_error in sys_init_connect. Since now we do not
        reset the diagnostics area in net_send_error (it's reset at the beginning
        of the next statement), we can access it safely even after 
        execute_init_command.
      sql/sql_db.cc:
        Update the code to satisfy the invariant that the diagnostics area is never
        assigned twice.
        Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if 
        mysql.proc does not exist".
      sql/sql_delete.cc:
        Change multi-delete to abort in abort(), as per select_send protocol.
        Fixes the merge error with the test for Bug 29136
      sql/sql_derived.cc:
        Use getters to access error information.
      sql/sql_insert.cc:
        Use getters to access error information.
      sql-common/client.c:
        Rename last_error to client_last_error, last_errno to client_last_errno.
      sql/sql_parse.cc:
        Remove hacks with no_send_error. Deploy net_end_statement().
        
        The story of COM_SHUTDOWN is interesting. Long story short, the server 
        would become on its death's door, and only no_send_ok/no_send_error assigned
        by send_ok()/net_send_error() would hide its babbling from the client.
        
        First of all, COM_QUIT does not require a response. So, the comment saying
        "Let's send a response to possible COM_QUIT" is not only groundless 
        (even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after 
        COM_SHUTDOWN), it's plainly incorrect.
        
        Secondly, besides this additional 'OK' packet to respond to a hypothetical
        COM_QUIT, there was the following code in dispatch_command():
        
        if (thd->killed)
          thd->send_kill_message();
        if (thd->is_error()
          net_send_error(thd);
        
        This worked out really funny for the thread through which COM_SHUTDOWN
        was delivered: we would get COM_SHUTDOWN, say okay, say okay again, 
        kill everybody, get the kill signal ourselves, and then attempt to say 
        "Server shutdown in progress" to the client that is very likely long gone.
        
        This all became visible when asserts were added that the Diagnostics_area
        is not assigned twice.
        
        Move query_cache_end_of_result() to the end of dispatch_command(), since
        net_send_eof() has been moved there. This is safe, query_cache_end_of_result()
        is a no-op if there is no started query in the cache.
        
        Consistently use select_send interface to call abort() or send_eof()
        depending on the operation result.
        
        Remove thd->fatal_error() from reset_master(), it was a no-op. 
        in hacks with no_send_error woudl save us
        from complete breakage of the client/server protocol.
        
        Consistently use select_send::abort() whenever there is an error, 
        and select_send::send_eof() in case of success.
        The issue became visible due to added asserts.

      Bug #27571 asynchronousity in setting mysql_`query`::error and · 95f3db7b

                 Query_log_event::error_code
      
      A query can perform completely having the local var error of mysql_$query
      zero, where $query in insert, update, delete, load,
      and be  binlogged with error_code e.g KILLED_QUERY while there is no
      reason do to so.
      That can happen because Query_log_event consults thd->killed flag to
      evaluate error_code.
      
      Fixed with implementing a scheme suggested and partly implemented at
      time of bug@22725 work-on. error_status is cached immediatly after the
      control leaves the main rows-loop and that instance always corresponds
      to `error' the local of mysql_$query functions. The cached value
      is passed to Query_log_event constructor, not the default thd->killed
      which can be changed in between of the caching and the constructing.

      Bug #29136 erred multi-delete on trans table does not rollback the statement · c8b6d105
      unknown authored
      similar to bug_27716, but it was stressed on in the synopsis on that there is another
      side of the artifact affecting behaviour in transaction.
      
      Fixed with deploying multi_delete::send_error() - otherwise never called - and refining its logic
      to perform binlogging job if needed.
      
      The changeset includes the following side effects:
      - added tests to check bug_23333's scenarios on the mixture of tables for multi_update;
      - fixes bug@30763 with two-liner patch and a test coinciding to one added for bug_23333.

      mysql-test/t/mix_innodb_myisam_binlog.test:
        multi-update  and multi-delete of mixure of ta and not-ta tables tests added (relates to bug_23333).
      mysql-test/t/multi_update.test:
        testing another branch of mult-delete: send_eof() (binloggin there), send_error (early return)
      sql/sql_class.h:
        a new flag to designate the fact the statement's error has been handled.
        The flag is checked by ::send_error() methods (multi_update and _delete classes)
      sql/sql_delete.cc:
        expanding multi_delete::send_error to 
        1. early return if error_handled == t
        2. binlogging locally if there was a non-trans table modified side effect
      sql/sql_parse.cc:
        adding multi_update::send_error which can perform binlogging and rollback job in needed
      sql/sql_update.cc:
        issues relating to
         
        1. bug_27716 with zeroing of `updated' to serve as the flag of early return from send_error().
           The flag is changed to be a new member error_handled; also moved outside binlogging branch.
           The reason for this change is that bug_23333 fixes were pushed after the bug_27716's and they
           left this flaw (also no test coverage).
        2. bug_30763 with assertion on trans_safe. I decide to make 2 liner fix for that bug here instead of to remove
           those two assertions. This new bug test case is the same as for multi-update on the mixure of tables.
           The rational for this fix:
           presumption for mutli_update::trans_safe to be set to zero at
           multi_update::multi_update or multi_update::initialize_tables() is incorrect.
        
           trans_safe := false should happen only when a non-transactional table gets modified. 
           Therefore, at initialization the member must be be set to true.

      Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack
        
      Once had been set the flag might later got reset inside of a stored routine 
      execution stack.
      The reason was in that there was no check if a new statement started at time 
      of resetting.
      The artifact affects most of binlogable DML queries. Notice, that multi-update 
      is wrapped up within
        bug@27716 fix, multi-delete bug@29136.
        
      Fixed with saving parent's statement flag of whether the statement modified 
      non-transactional table, and unioning (merging) the value with that was gained 
      in mysql_execute_command.
        
      Resettling thd->no_trans_update members into thd->transaction.`member`;
      Asserting code;
      Effectively the following properties are held.
        
      1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table
         reflects the fact if such a table got modified by the substatement.
         That also respects THD::really_abort_on_warnin() requirements.
      2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as
         the union of the values of all invoked sub-statements.
         That fixes this bug#27417;
      
      Computing of thd->transaction.all.modified_non_trans_table is refined to base to 
      the stmt's value for all the case including insert .. select statement which 
      before the patch had an extra issue bug@28960.
      Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in
      to temp_table select. 
        
      The supplied test verifies limitely, mostly asserts. The ultimate testing is defered
      for bug@13270, bug@23333.

      Bug#28158 - table->read_set is set incorrectly, · afbac007
      unknown authored
              causing wrong error message in Falcon
      
      An error message about a duplicate key could show a wrong key
      value when not all columns of the key were used to select the
      rows for update.
      
      Some storage engines return a record with only the selected
      columns filled.
      
      This is fixed by re-reading the record with a read_set which
      includes all columns of the duplicate key after a duplicate key
      error happens and before the error message is printed.

        Added a function for re-reading a record with a read_set
        that contains all fields used by a duplicate key.
        Called the function before every call to handler::print_error(),
        which could print a duplicate key value.

      Bug#29310: An InnoDB table was updated when the data wasn't actually changed. · a68a457b
      unknown authored
      When a table is being updated it has two set of fields - fields required for
      checks of conditions and fields to be updated. A storage engine is allowed
      not to retrieve columns marked for update. Due to this fact records can't
      be compared to see whether the data has been changed or not. This makes the
      server always update records independently of data change.
      
      Now when an auto-updatable timestamp field is present and server sees that
      a table handle isn't going to retrieve write-only fields then all of such
      fields are marked as to be read to force the handler to retrieve them.
      
      
      mysql-test/r/innodb_mysql.result:
        Added a test case for the bug#29310: An InnoDB table was updated when the data wasn't actually changed.

      Bug #29157: UPDATE, changed rows incorrect · ba4682ae
      unknown authored
      Sometimes the number of really updated rows (with changed
      column values) cannot be determined at the server level
      alone (e.g. if the storage engine does not return enough
      column values to verify that). So the only dependable way
      in such cases is to let the storage engine return that
      information if possible.
      Fixed the bug at server level by providing a way for the 
      storage engine to return information about wether it 
      actually updated the row or the old and the new column 
      values are the same. It can do that by returning 
      HA_ERR_RECORD_IS_THE_SAME in ha_update_row().
      Note that each storage engine may choose not to try to
      return this status code, so this behaviour remains 
      storage engine specific.

      Bug #27716 multi-update did partially and has not binlogged · 6b94fc57
      unknown authored
      Implementation of mysql_multi_update did not call multi_update::send_error method in some cases 
      (see the test reported on bug page and test cases in changeset).
      
      Fixed with deploying the method, ::send_error() is refined to get binlogging code which works whenever 
      there is modified non-transactional table.
      thd->no_trans_update.stmt flag is set in to TRUE to ease testing though being the beginning of relative 
      bug#27417 fix (addresses a part of those issues).
      Eliminating two minor issues (small bugs) in multi_update methods.
      This patch for multi-update also addresses a part of the issues reported in bug#13270,bug#23333.

      sql/sql_update.cc:
        making a call to multi_update::send_error when mysql_select return an error;
        deploying binlogging inside of ::send_error;
        refining multi_update::send_eof() to mark binlogging work done when its call to ::do_updates() errs
        and the query is binlogged with the error. ::send_error() will be called after all but
        do not do anything;
        thd->no_trans_update.stmt is corrected to be set to TRUE according to the existed code pattern. 
        Although this part relates to another bugs (bug#27417 etc) it is needed here for testing;
        Eliminating a separate issue in multi_update::do_updates where                
        either one of the class members trans_safe, transactional_tables was          
        set after the per-table loop whereas both should be calculated during         
        looping. 
        Eliminating a separate issue in ::send_eof() where thd->no_trans_update.all won't be set TRUE when
        amoung others there'd be at least one modified transactional table.
        Binlogging is done to satisfy to general character bug#13270,bug#23333 so that those won't have
        fixes specific for multi-update.

      The result of the CHECK OPTION condition evaluation over an

      Bug#22725 Replication outages from ER_SERVER_SHUTDOWN (1053) set in replication events · f27bf2b4
      unknown authored
        
      The reason for the bug was that replaying of a query on slave could not be possible since its event
      was recorded with the killed error. Due to the specific of handling INSERT, which per-row-while-loop is 
      unbreakable to killing, the query on transactional table should have not appeared in binlog unless
      there was  a call to a stored routine that got interrupted with killing (and then there must be an error
      returned out of the loop).
         
      The offered solution added the following rule for binlogging of INSERT that accounts the above
      specifics:
      For INSERT on transactional-table if the error was not set the only raised flag
      is harmless and is ignored via masking out on time of creation of binlog event.
         
      For both table types the combination of raised error and KILLED flag indicates that there
      was potentially partial execution on master and consistency is under the question.
      In that case the code continues to binlog an event with an appropriate killed error.
       
      The fix relies on the specified behaviour of stored routine that must propagate the error 
      to the top level query handling if the thd->killed flag was raised in the routine execution.
         
      The patch adds an arg with the default killed-status-unset value to Query_log_event::Query_log_event.
      
      
      sql/log_event.cc:
        killed_status as the value of thd->killed can be passed as an arg to the constructor.
        if the value is different from the default the arg is set to the current thd->killed value.
        A caller might need to masquerade thd->killed with THD::NOT_KILLED.
        So far only mysql_insert() uses such explicit way to tell the constructor about killing status.
      sql/log_event.h:
        default arg to the constructor with meaning of killed status of the query. 
        if the arg is not explicitly provided the status of thd->killed will be snapshot 
        inside of the constuctor, which is potentially incorrect (see bug#27571)
      sql/sql_class.h:
        extending killed_state with no-state member.
      sql/sql_insert.cc:
        ignore the KILLED flag incl KILL_BAD_DATA when the INSERT query event 
        is created without an `error';

      database.
      
      If a user has a right to update anything in the current database then the 
      access was granted and further checks of access rights for underlying tables
      wasn't done correctly. The check is done before a view is opened and thus no
      check of access rights for underlying tables can be carried out.
      This allows a user to update through a view a table from another database for
      which he hasn't enough rights.
      
      Now the mysql_update() and the mysql_test_update() functions are forces
      re-checking of access rights after a view is opened.

      WL#3817: Simplify string / memory area types and make things more consistent (first part) · f252f924
      unknown 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

      Fix for bug #22364 "Inconsistent "matched rows" when executing UPDATE" · c705567e
      unknown authored
      In multi_update::send_data(), the counter of matched rows was not correctly incremented, when during insertion of a new row to a temporay table it had to be converted from HEAP to MyISAM.
      
      This fix changes the logic to increment the counter of matched rows in the following cases:
      1. If the error returned from write_row() is zero.
      2. If the error returned from write_row() is non-zero, is neither HA_ERR_FOUND_DUPP_KEY nor HA_ERR_FOUND_DUPP_UNIQUE, and a call to create_myisam_from_heap() succeeds.

      Bug #26242 UPDATE with subquery and triggers failing with cluster tables · 2efc0f51
      unknown authored
      In certain cases AFTER UPDATE/DELETE triggers on NDB tables that referenced
      subject table didn't see the results of operation which caused invocation
      of those triggers. In other words AFTER trigger invoked as result of update
      (or deletion) of particular row saw version of this row before update (or
      deletion).
      
      The problem occured because NDB handler in those cases postponed actual
      update/delete operations to be able to perform them later as one batch.
      
      This fix solves the problem by disabling this optimization for particular
      operation if subject table has AFTER trigger for this operation defined.
      To achieve this we introduce two new flags for handler::extra() method:
      HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH.
      These are called if there exists AFTER DELETE/UPDATE triggers during a
      statement that potentially can generate calls to delete_row()/update_row().
      This includes multi_delete/multi_update statements as well as insert statements
      that do delete/update as part of an ON DUPLICATE statement.
      
      
      include/my_base.h:
        Added HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible.

      Bug #27395 OPTION_STATUS_NO_TRANS_UPDATE is not preserved at the end of SF() · 4a76ac5f
      unknown authored
      thd->options' OPTION_STATUS_NO_TRANS_UPDATE bit was not restored at the end of SF() invocation, where
      SF() modified non-ta table.
      As the result of this artifact it was not possible to detect whether there were any side-effects when
      top-level query ends. 
      If the top level query table was not modified and the bit is lost there would be no binlogging.
      
      Fixed with preserving the bit inside of thd->no_trans_update struct. The struct agregates two bool flags
      telling whether the current query and the current transaction modified any non-ta table.
      The flags stmt, all are dropped at the end of the query and the transaction.

      Bug#8407 (Stored functions/triggers ignore exception handler) · 266a7fff
      unknown authored
      Bug 18914 (Calling certain SPs from triggers fail)
      Bug 20713 (Functions will not not continue for SQLSTATE VALUE '42S02')
      Bug 21825 (Incorrect message error deleting records in a table with a
        trigger for inserting)
      Bug 22580 (DROP TABLE in nested stored procedure causes strange dependency
        error)
      Bug 25345 (Cursors from Functions)
      
      
      This fix resolves a long standing issue originally reported with bug 8407,
      which affect the behavior of Stored Procedures, Stored Functions and Trigger
      in many different ways, causing symptoms reported by all the bugs listed.
      In all cases, the root cause of the problem traces back to 8407 and how the
      server locks tables involved with sub statements.
      
      Prior to this fix, the implementation of stored routines would:
      - compute the transitive closure of all the tables referenced by a top level
      statement
      - open and lock all the tables involved
      - execute the top level statement
      "transitive closure of tables" means collecting:
      - all the tables,
      - all the stored functions,
      - all the views,
      - all the table triggers
      - all the stored procedures
      involved, and recursively inspect these objects definition to find more
      references to more objects, until the list of every object referenced does
      not grow any more.
      This mechanism is known as "pre-locking" tables before execution.
      The motivation for locking all the tables (possibly) used at once is to
      prevent dead locks.
      
      One problem with this approach is that, if the execution path the code
      really takes during runtime does not use a given table, and if the table is
      missing, the server would not execute the statement.
      This in particular has a major impact on triggers, since a missing table
      referenced by an update/delete trigger would prevent an insert trigger to run.
      
      Another problem is that stored routines might define SQL exception handlers
      to deal with missing tables, but the server implementation would never give
      user code a chance to execute this logic, since the routine is never
      executed when a missing table cause the pre-locking code to fail.
      
      With this fix, the internal implementation of the pre-locking code has been
      relaxed of some constraints, so that failure to open a table does not
      necessarily prevent execution of a stored routine.
      
      In particular, the pre-locking mechanism is now behaving as follows:
      
      1) the first step, to compute the transitive closure of all the tables
      possibly referenced by a statement, is unchanged.
      
      2) the next step, which is to open all the tables involved, only attempts
      to open the tables added by the pre-locking code, but silently fails without
      reporting any error or invoking any exception handler is the table is not
      present. This is achieved by trapping internal errors with
      Prelock_error_handler
      
      3) the locking step only locks tables that were successfully opened.
      
      4) when executing sub statements, the list of tables used by each statements
      is evaluated as before. The tables needed by the sub statement are expected
      to be already opened and locked. Statement referencing tables that were not
      opened in step 2) will fail to find the table in the open list, and only at
      this point will execution of the user code fail.
      
      5) when a runtime exception is raised at 4), the instruction continuation
      destination (the next instruction to execute in case of SQL continue
      handlers) is evaluated.
      This is achieved with sp_instr::exec_open_and_lock_tables()
      
      6) if a user exception handler is present in the stored routine, that
      handler is invoked as usual, so that ER_NO_SUCH_TABLE exceptions can be
      trapped by stored routines. If no handler exists, then the runtime execution
      will fail as expected.
      
      With all these changes, a side effect is that view security is impacted, in
      two different ways.
      
      First, a view defined as "select stored_function()", where the stored
      function references a table that may not exist, is considered valid.
      The rationale is that, because the stored function might trap exceptions
      during execution and still return a valid result, there is no way to decide
      when the view is created if a missing table really cause the view to be invalid.
      
      Secondly, testing for existence of tables is now done later during
      execution. View security, which consist of trapping errors and return a
      generic ER_VIEW_INVALID (to prevent disclosing information) was only
      implemented at very specific phases covering *opening* tables, but not
      covering the runtime execution. Because of this existing limitation,
      errors that were previously trapped and converted into ER_VIEW_INVALID are
      not trapped, causing table names to be reported to the user.
      This change is exposing an existing problem, which is independent and will
      be resolved separately.

      WL#3527: Extend IGNORE INDEX so places where index is ignored · 79542930
      unknown authored
               can be specified
      Currently MySQL allows one to specify what indexes to ignore during
      join optimization. The scope of the current USE/FORCE/IGNORE INDEX 
      statement is only the FROM clause, while all other clauses are not 
      affected.
      
      However, in certain cases, the optimizer
      may incorrectly choose an index for sorting and/or grouping, and
      produce an inefficient query plan.
      
      This task provides the means to specify what indexes are
      ignored/used for what operation in a more fine-grained manner, thus
      making it possible to manually force a better plan. We do this
      by extending the current IGNORE/USE/FORCE INDEX syntax to:
      
      IGNORE/USE/FORCE INDEX [FOR {JOIN | ORDER | GROUP BY}]
      
      so that:
      - if no FOR is specified, the index hint will apply everywhere.
      - if MySQL is started with the compatibility option --old_mode then
        an index hint without a FOR clause works as in 5.0 (i.e, the 
        index will only be ignored for JOINs, but can still be used to
        compute ORDER BY).
      
      See the WL#3527 for further details.

      Bug#25122: Views based on a self-joined table aren't insertable. · 1437a9c5
      unknown authored
      When INSERT is done over a view the table being inserted into is 
      checked to be unique among all views tables. But if the view contains
      self-joined table an error will be thrown even if all tables are used under
      different aliases.
      
      The unique_table() function now also checks tables' aliases when needed.

      Bug#24795: SHOW PROFILE
      
      Profiling is only partially functional on some architectures.  Where 
      there is no getrusage() system call, presently Null values are 
      returned where it would be required.  Notably, Windows needs some love 
      applied to make it as useful.
      
        Syntax this adds:
        
        SHOW PROFILES
        
        SHOW PROFILE [types] [FOR QUERY n] [OFFSET n] [LIMIT n]
         where "n" is an integer
         and "types" is zero or many (comma-separated) of
            "CPU"
            "MEMORY" (not presently supported)
            "BLOCK IO"
            "CONTEXT SWITCHES"
            "PAGE FAULTS"
            "IPC"
            "SWAPS"
            "SOURCE"
            "ALL"
      
      It also adds a session variable (boolean) "profiling", set to "no"
      by default, and (integer) profiling_history_size, set to 15 by 
      default.
      
      This patch abstracts setting THDs' "proc_info" behind a macro that 
      can be used as a hook into the profiling code when profiling 
      support is compiled in.  All future code in this line should use
      that mechanism for setting thd->proc_info.
      
      ---
      
      Tests are now set to omit the statistics.
      
      ---
      
      Adds an Information_schema table, "profiling" for access to 
      "show profile" data.
