02a4354044 Bug #32709: Assertion failed: trx_data->empty(), file log.cc
The assertion indicates that some data was left in the transaction
cache when the server was shut down, which means that a previous
statement did not commit or rollback correctly.

What happened was that a bug in the rollback of a transactional
table caused the transaction cache to be emptied, but not reset.
The error can be triggered by having a failing UPDATE or INSERT,
on a transactional table, causing an implicit rollback.

Fixed by always flushing the pending event to reset the state
properly.


mysql-test/extra/rpl_tests/rpl_row_basic.test:
  Testing that a failed update (that writes some rows to the
  transaction cache) does not cause the transaction cache to
  hold on to the data or forget to reset the transaction cache.
sql/log.cc:
  Added call to remove pending event when the transaction cache
  is emptied instead of written to binary log. The call will also
  clear the outstanding table map count so that the cache is not
  left it in a state of "empty but not reset".
  
  Added function MYSQL_BIN_LOG::remove_pending_rows_event().

  Added function MYSQL_BIN_LOG::remove_pending_rows_event().

e73e7bb9ae Bug#35577 (CREATE PROCEDURE causes either crash or syntax error depending on
build)

The crash was caused by freeing the internal parser stack during the parser
execution.
This occured only for complex stored procedures, after reallocating the parser
stack using my_yyoverflow(), with the following C call stack:
- MYSQLparse()
- any rule calling sp_head::restore_lex()
- lex_end()
- x_free(lex->yacc_yyss), xfree(lex->yacc_yyvs)

The root cause is the implementation of stored procedures, which breaks the
assumption from 4.1 that there is only one LEX structure per parser call.

The solution is to separate the LEX structure into:
- attributes that represent a statement (the current LEX structure),
- attributes that relate to the syntax parser itself (Yacc_state),
so that parsing multiple statements in stored programs can create multiple
LEX structures while not changing the unique Yacc_state.

Now, Yacc_state and the existing Lex_input_stream are aggregated into
Parser_state, a structure that represent the complete state of the (Lexical +
Syntax) parser.

e66ba2a74b Bug#36443 Server crashes when executing insert when insert trigger on table
The crash appeared to be a result of allocating an instance of Discrete_interval 
      automatically that that was referred in out-of-declaration scope.
                        
      Fixed with correcting backing up and restoring scheme of
      auto_inc_intervals_forced, introduced by bug#33029, by means of shallow copying;
      added simulation code that forces executing those fixes of the former bug that
      targeted at master-and-slave having incompatible bug#33029-prone versions.

2cc7999b12 Bug #32858: Erro: "Incorrect usage of UNION and INTO" does not take
subselects into account
  
It is forbidden to use the SELECT INTO construction inside UNION statements
unless on the last SELECT of the union. The parser records whether it 
has seen INTO or not when parsing a UNION statement. But if the INTO was
legally used in an outer query, an error is thrown if UNION is seen in a
subquery. Fixed in 5.0 by remembering the nesting level of INTO tokens and 
mitigate the error unless it collides with the UNION.

bd2a732812 WL#4165 "Prepared statements: validation".
Add metadata validation to ~20 more SQL commands. Make sure that
these commands actually work in ps-protocol, since until now they
were enabled, but not carefully tested.
Fixes the ml003 bug found by Matthias during internal testing of the
patch.

sql/mysql_priv.h:

sql/sp_head.cc:
  Changed the way the observer is removed in case of stored procedures
  to support validation prepare stmt from "call p1(<expr>)": whereas
  tables used in the expression must be validated, substatements
  of p1 must not.
  The previous scheme used to silence the observer only in stored
  functions and triggers.
sql/sql_class.cc:
  Now the observer is silenced in sp_head::execute(). Remove it from
  Sub_statement_state.
sql/sql_class.h:
  Now the observer is silenced in sp_head::execute(). Remove it from
  Sub_statement_state.
sql/sql_parse.cc:
  Add CF_REEXECUTION_FRAGILE to 20 more SQLCOMs that need it.
sql/sql_prepare.cc:
  Add metadata validation to ~20 new SQLCOMs that need it.
  Fix memory leaks with expressions used in SHOW DATABASES and CALL
  (and prepared statements).
  We need to fix all expressions at prepare, since if these expressions
  use subqueries, there are one-time transformations of the parse
  tree that must be done at prepare. 
  List of fixed commands includes: SHOW TABLES, SHOW DATABASES,
  SHOW TRIGGERS, SHOW EVENTS, SHOW OPEN TABLES,SHOW KEYS, SHOW FIELDS, 
  SHOW COLLATIONS, SHOW CHARSETS, SHOW VARIABLES, SHOW TATUS, SHOW TABLE
  STATUS, SHOW PROCEDURE STATUS, SHOW FUNCTION STATUS, CALL.

a63dde5a5b Tentative implementation of
WL#4165 Prepared statements: validation 
WL#4166 Prepared statements: automatic re-prepare
Fixes
Bug#27430 Crash in subquery code when in PS and table DDL changed after PREPARE
Bug#27690 Re-execution of prepared statement after table was replaced with a view crashes
Bug#27420 A combination of PS and view operations cause error + assertion on shutdown

The basic idea of the patch is to keep track of table metadata between
prepared statement prepare and execute. If some table used in the statement
has changed, the prepared statement is re-prepared before execution.

See WL#4165 and WL#4166 contents and comments in the code for details
of the implementation.


include/my_global.h:
  Remove 'register' keyword to avoid warnings when swapping large structures
  that don't fit into a register. Any modern compiler is capable of placing
  a variable in a register when that would benefit performance.
mysql-test/r/ps_1general.result:
  Update test results: since now we re-prepare automatically,
  more correct results are produced in prepare-ddl-execute scenario.
mysql-test/r/query_cache_merge.result:
  Ensure that the table definition cache is large enough for
  the test to pass in --ps-protocol
mysql-test/r/trigger.result:
  Update test results to reflect automatic statement reprepare.
mysql-test/t/disabled.def:
  Enable ps_ddl.test, which now passes.
mysql-test/t/ps_1general.test:
  Since now we re-execute prepared statements after DDL successfully,
  change the test to produce repeatable results. Remove expectancy of
  an error in one place where now we automatically reprepare the prepared
  statement.

  Ensure the table definition cache is large enough for the test to pass
  in --ps-protocol
mysql-test/t/trigger.test:
  Sinc
sql/item.cc:
  Implement Item_param "copy" functionality, used at re-prepare of
  a prepared statement.
  We copy the type of the original parameter, and move the assigned value,
  if any. Sic, the value is "moved", since it can be quite big --
  e.g. in case we deal with a LONG DATA parameter.
  It's essential to move the value from the old parameter since
  at the time of re-prepare the client packet with the necessary information
  may be not available.
sql/item.h:
  Declare a new method used for reprepare.
sql/my_decimal.h:
  Implement "swap()" functionality of class my_decimal to be
  able to easily swap two decimal values.
sql/mysql_priv.h:
  Declare enum_metadata_type.
sql/mysqld.cc:
  Implement a status variable for the number of reprepared statements.
sql/sql_base.cc:
  Implement metadata version validation.
sql/share/errmsg.txt:
  Add two new error messages: ER_NEED_REPREPARE and ER_PS_REBIND.
  The first error (theoretically) never reaches the user.
  It is issued by the metadata validation framework when a metadata version
  has changed between prepare and execute. Later on it's intercepted
  and the statement is automatically re-prepared. Only if the error
  has occurred repeatedly MAX_REPREPARE_ATTEMTS (3) times do we
  return it to the user.
  
  The second error is issued when after re-prepare we discover
  that the metadata we sent over to the client using the binary
  protocol differs drammatically from the new result set metadata 
  that the reprepared statement produces (e.g. number of result
  set columns is different).
sql/sql_class.cc:
  Implement metadata version validation framework.
sql/sql_class.h:
  Declarations for metadata version validation framework.
sql/sql_parse.cc:
  Mark commands for which we must invalidate and reprepare a prepared
  statement when metadata has changed.
sql/sql_prepare.cc:
  Implement WL#4165 and WL#4166 (limited support of metadata validation
  and re-prepare).
sql/table.h:
  Implement metadata validation.
tests/mysql_client_test.c:
  Add a test case for WL#4166

2a001d5389 Bug #35675 reset master finds assert if a binlog file can not be deleted
If a binlog file is manually replaced with a namesake directory the internal purging did
not handle the error of deleting the file so that eventually
a post-execution guards fires an assert.

f21ee5d00d BUG#33029 5.0 to 5.1 replication fails on dup key when inserting
using a trig in SP

For all 5.0 and up to 5.1.12 exclusive, when a stored routine or
trigger caused an INSERT into an AUTO_INCREMENT column, the
generated AUTO_INCREMENT value should not be written into the
binary log, which means if a statement does not generate
AUTO_INCREMENT value itself, there will be no Intvar event (SET
INSERT_ID) associated with it even if one of the stored routine
or trigger caused generation of such a value. And meanwhile, when
executing a stored routine or trigger, it would ignore the
INSERT_ID value even if there is a INSERT_ID value available set
by a SET INSERT_ID statement.

Starting from MySQL 5.1.12, the generated AUTO_INCREMENT value is
written into the binary log, and the value will be used if
available when executing the stored routine or trigger.

Prior fix of this bug in MySQL 5.0 and prior MySQL 5.1.12
(referenced as the buggy versions in the text below), when a
statement that generates AUTO_INCREMENT value by the top
statement was executed in the body of a SP, all statements in the
SP after this statement would be treated as if they had generated
AUTO_INCREMENT by the top statement.  When a statement that did
not generate AUTO_INCREMENT value by the top statement but by a
function/trigger called by it, an erroneous Intvar event would be
associated with the statement, this erroneous INSERT_ID value
wouldn't cause problem when replicating between masters and
slaves of 5.0.x or prior 5.1.12, because the erroneous INSERT_ID
value was not used when executing functions/triggers. But when
replicating from buggy versions to 5.1.12 or newer, which will
use the INSERT_ID value in functions/triggers, the erroneous
value will be used, which would cause duplicate entry error and
cause the slave to stop.

The patch for 5.1 fixed it to ignore the SET INSERT_ID value when
executing functions/triggers if it is replicating from a master
of buggy versions, another patch for 5.0 fixed it not to generate
the erroneous Intvar event.

d5f09a13de BUG#33029 5.0 to 5.1 replication fails on dup key when inserting
using a trig in SP

For all 5.0 and up to 5.1.12 exclusive, when a stored routine or
trigger caused an INSERT into an AUTO_INCREMENT column, the
generated AUTO_INCREMENT value should not be written into the
binary log, which means if a statement does not generate
AUTO_INCREMENT value itself, there will be no Intvar event (SET
INSERT_ID) associated with it even if one of the stored routine
or trigger caused generation of such a value. And meanwhile, when
executing a stored routine or trigger, it would ignore the
INSERT_ID value even if there is a INSERT_ID value available set
by a SET INSERT_ID statement.

Starting from MySQL 5.1.12, the generated AUTO_INCREMENT value is
written into the binary log, and the value will be used if
available when executing the stored routine or trigger.

Prior fix of this bug in MySQL 5.0 and prior MySQL 5.1.12
(referenced as the buggy versions in the text below), when a
statement that generates AUTO_INCREMENT value by the top
statement was executed in the body of a SP, all statements in the
SP after this statement would be treated as if they had generated
AUTO_INCREMENT by the top statement.  When a statement that did
not generate AUTO_INCREMENT value by the top statement but by a
function/trigger called by it, an erroneous Intvar event would be
associated with the statement, this erroneous INSERT_ID value
wouldn't cause problem when replicating between masters and
slaves of 5.0.x or prior 5.1.12, because the erroneous INSERT_ID
value was not used when executing functions/triggers. But when
replicating from buggy versions to 5.1.12 or newer, which will
use the INSERT_ID value in functions/triggers, the erroneous
value will be used, which would cause duplicate entry error and
cause the slave to stop.

The patch for 5.0 fixed it not to generate the erroneous Intvar
event, another patch for 5.1 fixed it to ignore the SET INSERT_ID
value when executing functions/triggers if it is replicating from
a master of buggy versions.

  add $binlog_start parameter to set the start position when show binlog events, if not set a default value will be used.

b6595704ef Bug#34726: open_tables() crashes server if running with --debug
The DBUG code emits the current value of the proc_info member of THD,
which may be set to NULL.  It was wrong to dereference that value
with the format string %s without verifying that it was valid.

Now, insert an inline test that substitutes the string "(null)" for
NULL pointers.


sql/sql_class.cc:
  Dereferencing a NULL is illegal (though not fatal for %s on some 
  platforms), and we have no assurance that the caller didn't call us 
  with a valid string.

4b25d5b10c Applied InnoDB snapshot innodb-5.1-ss2298
Fixes the following bugs:

- Bug #33349: possible race condition revolving around data dictionary and repartitioning
  Introduce retry/sleep logic as a workaround for a transient bug
  where ::open fails for partitioned tables randomly if we are using
  one file per table.

- Bug #34053: normal users can enable innodb_monitor logging
  In CREATE TABLE and DROP TABLE check whether the table in question is one
  of the magic innodb_monitor tables and whether the user has enough rights
  to mess with it before doing anything else.

- Bug #22868: 'Thread thrashing' with > 50 concurrent conns under an upd-intensive workloadw
- Bug #29560: InnoDB >= 5.0.30 hangs on adaptive hash rw-lock 'waiting for an X-lock'

  Looks like these strings are "automatically" wrapped by MySQL in the
  following way:
  * newlines (\n) in the string are ignored
  * newline separator (\n) is inserted every 57 or so characters.
  * lots of white space is appended to each inserted new line.

526798dbb5 A fix and a test case for Bug#12713 "Error in a stored function called from
a SELECT doesn't cause ROLLBACK of statem".

The idea of the fix is to ensure that we always commit the current
statement at the end of dispatch_command(). In order to not issue
redundant disc syncs, an optimization of the two-phase commit
protocol is implemented to bypass the two phase commit if
the transaction is read-only.

  Disable the tests, for which this changeset reveals a bug:
  the injector thread does not always add 'statement commit' to the
  rows injected in circular replication set up.
  To be investigated separately.
sql/ha_ndbcluster_binlog.cc:
  Add close_thread_tables() to run_query: this ensures
  that all tables are closed and there is no pending statement transaction.
sql/handler.cc:
  Implement optimisation of read-only transactions.
  If a transaction consists only of DML statements that do not change
  data, we do not perform a two-phase commit for it 
  (run one phase commit only).
sql/handler.h:
  Implement optimisation of read-only transactions.
  If a transaction consists only of DML statements that do not change
  data, we do not perform a two-phase commit for it 
  (run one phase commit only).
sql/log.cc:
  Mark the binlog transaction read-write whenever it's started.
  We never read from binlog, so it's safe and least intrusive to add
  this mark up here.
sql/log_event.cc:
  Update to the new layout of thd->transaction.
sql/rpl_injector.cc:
  Always commit statement transaction before committing the global one.
sql/sp.cc:
  Ad comments.
sql/sp_head.cc:
  Add comments.
sql/sql_base.cc:
  Commit transaction at the end of the statement. Always.
sql/sql_class.cc:
  Update thd_ha_data to return the right pointer in the new layout.
  
  Fix select_dumpvar::send_data to properly return operation status.
  A test case from commit.inc would lead to an assertion failure in the 
  diagnostics area (double assignment). Not test otherwise by the test suite.
sql/sql_class.h:
  Implement a new layout of storage engine transaction info in which 
  it is easy to access all members related to the handlerton only
  based on ht->slot.
sql/sql_cursor.cc:
  Update to the new layout of thd->transaction.
sql/sql_delete.cc:
  Remove wrong and now redundant calls to ha_autocommit_or_rollback.
  The transaction is committed in one place, at the end of the statement.
  Remove calls to mysql_unlock_tables, since some engines count locks
  and commit statement transaction in unlock_tables(), which essentially
  equates mysql_unlock_tables to ha_autocommit_or_rollback.
  Previously it was necessary to unlock tables soon because we wanted
  to avoid sending of 'ok' packet to the client under locked tables.
  This is no longer necessary, since OK packet is also sent from one place
  at the end of transaction.
sql/sql_do.cc:
  Add DO always clears the error, we must rollback the current
  statement before this happens. Otherwise the statement will be committed,
  and not rolled back in the end.
sql/sql_insert.cc:
  Remove wrong and now redundant calls to ha_autocommit_or_rollback.
  The transaction is committed in one place, at the end of the statement.
  Remove calls to mysql_unlock_tables, since some engines count locks
  and commit statement transaction in unlock_tables(), which essentially
  equates mysql_unlock_tables to ha_autocommit_or_rollback.
  Previously it was necessary to unlock tables soon because we wanted
  to avoid sending of 'ok' packet to the client under locked tables.
  This is no longer necessary, since OK packet is also sent from one place
  at the end of transaction.
sql/sql_load.cc:
  Remove wrong and now redundant calls to ha_autocommit_or_rollback.
  The transaction is committed in one place, at the end of the statement.
  Remove calls to mysql_unlock_tables, since some engines count locks
  and commit statement transaction in unlock_tables(), which essentially
  equates mysql_unlock_tables to ha_autocommit_or_rollback.
  Previously it was necessary to unlock tables soon because we wanted
  to avoid sending of 'ok' packet to the client under locked tables.
  This is no longer necessary, since OK packet is also sent from one place
  at the end of transaction.
sql/sql_parse.cc:
  Implement optimisation of read-only transactions: bypass 2-phase
  commit for them.
  Always commit statement transaction before commiting the global one.
  Fix an unrelated crash in check_table_access, when called from 
  information_schema.
sql/sql_partition.cc:
  Partitions commit at the end of a DDL operation.
  Make sure that send_ok() is done only if the commit has succeeded.
sql/sql_table.cc:
  Use ha_autocommit_or_rollback and end_active_trans everywhere.
  Add end_trans to mysql_admin_table, so that it leaves no pending
  transaction.
sql/sql_udf.cc:
  Remvove a redundant call to close_thread_tables()
sql/sql_update.cc:
  Remove wrong and now redundant calls to ha_autocommit_or_rollback.
  The transaction is committed in one place, at the end of the statement.
  Remove calls to mysql_unlock_tables, since some engines count locks
  and commit statement transaction in unlock_tables(), which essentially
  equates mysql_unlock_tables to ha_autocommit_or_rollback.

215625b143 Fix for Bug#31222: com_% global status counters
behave randomly with mysql_change_user.
  
The problem was that global status variables were not updated
in THD::check_user(), so thread statistics were lost after
COM_CHANGE_USER.
  
The fix is to update global status variables with the thread ones
before preparing the thread for new user.

93e3057ba5 Bug #32858: Erro: "Incorrect usage of UNION and INTO" does not take
subselects into account

It is forbidden to use the SELECT INTO construction inside UNION statements
unless on the last SELECT of the union. The parser records whether it 
has seen INTO or not when parsing a UNION statement. But if the INTO was
legally used in an outer query, an error is thrown if UNION is seen in a
subquery. Fixed in 5.0 by remembering the nesting level of INTO tokens and 
mitigate the error unless it collides with the UNION.

2a0d2fef51 Bug#12713 "Error in a stored function called from a SELECT doesn't
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.
sql/sql_partition.cc:
  Always set an error in THD whenever there is a call to fatal_error().
sql/sql_prepare.cc:
  Deploy class Diagnostics_area.
  Remove the unnecessary juggling with the protocol in 
  Select_fetch_protocol_binary::send_eof(). EOF packet format is 
  protocol-independent.
sql/sql_select.cc:
  Call fatal_error() directly in opt_sum_query.
  Call my_error() whenever we call thd->fatal_error().
sql/sql_servers.cc:
  Use getters to access error information in THD.
sql/sql_show.cc:
  Use getters to access error information in THD.
  
  Add comments.
  
  Call my_error() whenever we call fatal_error().
sql/sql_table.cc:
  Replace hacks with no_send_ok with the interface of the diagnostics area.
  
  Clear the error if ENOENT error in ha_delete_table().
sql/sql_update.cc:
  Introduce multi_update::abort(), which is the proper way to abort a
  multi-update. This fixes the merge conflict between this patch and
  the patch for Bug 29136.
sql/table.cc:
  Use a getter to access error information in THD.
sql/tztime.cc:
  Use a getter to access error information in THD.
