message:
  Bug #47304 Test main.mdl_sync fails on embedded server

  The problem was that SHOW PROCESSLIST was trying to access
  a thread that was not properly running and therefore had an 
  uninitialized mutex.

  This patch explicitly resets thd->mysys_var after each embedded
  server command to prevent the mutex from being accessed in an
  illegal state.

  The patch also re-enables lock_multi.test and mdl_sync.test for 
  embedded server as they had been disabled because of this bug.

8ec23470f1 Backport of revno 2630.28.10, 2630.28.31, 2630.28.26, 2630.33.1,
2630.39.1, 2630.28.29, 2630.34.3, 2630.34.2, 2630.34.1, 2630.29.29,
2630.29.28, 2630.31.1, 2630.28.13, 2630.28.10, 2617.23.14 and
some other minor revisions.

This patch implements: 

WL#4264 "Backup: Stabilize Service Interface" -- all the
server prerequisites except si_objects.{h,cc} themselves (they can
be just copied over, when needed).

WL#4435: Support OUT-parameters in prepared statements.

(and all issues in the initial patches for these two
tasks, that were discovered in pushbuild and during testing).

Bug#39519: mysql_stmt_close() should flush all data
associated with the statement.

After execution of a prepared statement, send OUT parameters of the invoked
stored procedure, if any, to the client.

When using the binary protocol, send the parameters in an additional result
set over the wire.  When using the text protocol, assign out parameters to
the user variables from the CALL(@var1, @var2, ...) specification.

The following refactoring has been made:
  - Protocol::send_fields() was renamed to Protocol::send_result_set_metadata();
  - A new Protocol::send_result_set_row() was introduced to incapsulate
    common functionality for sending row data.
  - Signature of Protocol::prepare_for_send() was changed: this operation
    does not need a list of items, the number of items is fully sufficient.

The following backward incompatible changes have been made:
  - CLIENT_MULTI_RESULTS is now enabled by default in the client;
  - CLIENT_PS_MULTI_RESUTLS is now enabled by default in the client.

include/mysql.h:
  Add a new flag to MYSQL_METHODS::flush_use_result
  function pointer. This flag determines if all results
  should be flushed or only the first one:
      
  - if flush_all_results is TRUE, then cli_flush_use_result()
    will read/flush all pending results. I.e. it will read
    all packets while server status attribute indicates that
    there are more results. This is a new semantic, required
    to fix the bug.
              
  - if flush_all_results is FALSE, the old sematic
    is preserved -- i.e. cli_flush_use_result() reads data
    until first EOF-packet.
include/mysql.h.pp:
  Update the ABI with new calls (compatible changes).
include/mysql_com.h:
  Add CLIENT_PS_OUT_PARAMS -- a client capability indicating that the client supportsю
libmysql/libmysql.c:
  Add mysql_stmt_next_result() -- analogue of mysql_next_result() for binary protocol.
  Fix a minor bug in alloc_fields() -- not all members were copied over,
  and some only shallow-copied (catalog).
  Flush all results in mysql_stmt_close() (Bug#39519).
libmysqld/lib_sql.cc:
  Rename send_fields() -> send_result_set_metadata().
  Refactoring: change prepare_for_send() so that it accepts only 
  what it really needs -- a number of elements in the list.
mysql-test/r/ps.result:
  Update results: WL#4435.
mysql-test/t/ps.test:
  WL#4435: A test case for an SQL-part of the problem.
sql-common/client.c:
  Bug#39519.
  Implement new functionality in cli_flush_use_result():
  if flush_all_delete is TRUE, then it should read/flush
  all pending results.
sql/Makefile.am:
  Add a new header sql_prepare.h to the list
  of build headers.
sql/events.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/handler.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/mysql_priv.h:
  Move sql_prepare.cc-specific declarations to a new
  header - sql_prepare.h.
sql/procedure.h:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/protocol.cc:
  Move the logic responsible for sending of one result
  set row to the Protocol class. Define a template
  for end-of-statement action. 
  Refactoring: change prepare_for_send() so that it accepts 
  only what it really needs -- a number of elements in the list.
  Rename send_fields() to send_result_set_metadata().
sql/protocol.h:
  Update with new declarations (WL#4435).
  Rename send_fields() -> send_result_set_metadata().
  prepare_for_send() only needs the number of columns to send,
  and doesn't use the item list - update signature to require
  only what's needed.
  Add a new protocol type -- Protocol_local.
sql/repl_failsafe.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/slave.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_acl.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_base.cc:
  Include sql_prepare.h (for Reprepare_observer).
sql/sql_cache.cc:
  Extend the query cache flags block to be able
  to store a numeric id for the result format,
  not just a flag binary/non-binary.
sql/sql_class.cc:
  Update to use the rename of Protocol::send_fields()
  to Protocol::send_result_set_metadata().
  Use Protocol::send_one_result_set_row().
sql/sql_class.h:
  Move the declaration of Reprepare_observer to the 
  new header - sql_prepare.h.
  Update to the new signature of class Protocol::send_fields().
sql/sql_connect.cc:
  Use a protocol template method instead of
  raw NET layer API at the end of a statement.
sql/sql_cursor.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_error.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_handler.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
  Use new method Protocol::send_one_result_set_row().
sql/sql_help.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_lex.cc:
  Initialize multi_statements variable.
  Add a handy constant for empty lex
  string.
sql/sql_lex.h:
  Add a separate member for a standalone
  parsing option - multi-statements support.
sql/sql_list.cc:
  sql_list.h is a standalone header now, 
  no need to include mysql_priv.h.
sql/sql_list.h:
  Make sql_list.h a stand-alone header.
sql/sql_parse.cc:
  Include sql_prepare.h for prepared
  statements- related declarations.
  Use a new Protocol template method to end
  each statement (send OK, EOF or ERROR to
  the client).
sql/sql_prepare.cc:
  Implement Execute Direct API (WL#4264), 
  currently unused. It will be used by the service
  interface (Backup).
  Use a new header - sql_prepare.h.
  Add support for OUT parameters in the 
  binary and text protocol (prepared statements 
  only).
sql/sql_prepare.h:
  Add a new header to contain (for now)
  all prepared statement- external
  related declarations.
sql/sql_profile.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_repl.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_select.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_show.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_string.h:
  Add a way to convert a String to LEX_STRING.
sql/sql_table.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().
sql/sql_update.cc:
  Remove an extraneous my_error(). The error
  is already reported in update_non_unique_table_error().
sql/sql_yacc.yy:
  Support for multi-statements is an independent
  property of parsing, not derived from 
  the protocol type.
tests/mysql_client_test.c:
  Add tests for WL#4435 (binary protocol).

0da357645c Bug #44651 "have_community_features" variable should be renamed
"have_profiling"

1) Renamed have_community_features server system variable to
have_profiling.
2) Removed eable-community-features configure option and
ENABLE_COMMUNITY_FEATURES macro.
3) Removed COMMUNITY_SERVER macro and replaced its usage by 
ENABLED_PROFILING.

Only --enable-profiling is now needed to enable profiling.
It was the only existing "community feature", so there was
no need for both configure options.

Using --enable-community-features will give a warning message
since it no longer exists.

12e822039d Fix for BUG#42980 "Client doesn't set NUM_FLAG for DECIMAL and TIMESTAMP":
DECIMAL and TIMESTAMP used to have NUM_FLAG, but NEWDECIMAL was forgotten.
It's correct that TIMESTAMP does not have the flag nowadays (manual will be updated, connectors
developers will be notified).

client/mysqldump.c:
  IS_NUM_FIELD(f) removed and replaced by its definition (f>flags & NUM_FLAG).
include/mysql.h:
  - IS_NUM_FIELD() is removed because name is too close to IS_NUM() and it is not used a lot
  - INTERNAL_NUM_FIELD() is removed:
    * it forgets to test NEWDECIMAL (when IS_NUM() was updated for NEWDECIMAL we forgot
    to update INTERNAL_NUM_FIELD()), that's why client didn't mark NEWDECIMAL with NUM_FLAG (a bug).
    * it has an obsolete test for length of the TIMESTAMP field: test became accidentally wrong when length
    of TIMESTAMP was changed to always be 19 (when the format was changed from YYYYMMDDhhmmss to
    YYYY-MM-DD hh:mm:ss), never 8 or 14 anymore. That obsolete test caused TIMESTAMP to lose NUM_FLAG,
    which was an accidental but good change (see below).
    * IS_NUM() should be used instead
  - IS_NUM(f) is changed: TIMESTAMP used to be parsable as a number without quotes (when it was formatted as
  "YYYYMMDDhhmmss"); but it is not anymore (now that it is "YYYY-MM-DD hh:mm:ss"), so it should not have NUM_FLAG
  (mysqldump needs to quote TIMESTAMP values), so IS_NUM() should return false for it.
libmysqld/lib_sql.cc:
  use IS_NUM() instead of INTERNAL_NUM_FIELD()
mysql-test/r/bigint.result:
  result change: NEWDECIMAL fields now have NUM_FLAG (32768)
mysql-test/r/metadata.result:
  result change: NEWDECIMAL fields now have NUM_FLAG (32768)
mysql-test/r/mysqldump.result:
  DECIMAL columns are not quoted anymore by mysqldump. Which is ok, the parser does not need '' for them
mysql-test/r/ps_2myisam.result:
  result change: NEWDECIMAL fields now have NUM_FLAG (32768)
mysql-test/r/ps_3innodb.result:
  result change: NEWDECIMAL fields now have NUM_FLAG (32768)

f02800bd97 Backporting WL#3759 Optimize identifier conversion in client-server protocol
This patch provides performance improvements:
- send_fields() when character_set_results = latin1
  is now about twice faster for column/table/database
  names, consisting on ASCII characters.

Changes:

- Protocol doesn't use "convert" temporary buffer anymore,
  and converts strings directly to "packet".

- General conversion optimization: quick conversion
  of ASCII strings was added.

modified files:

include/m_ctype.h
- Adding a new flag.
- Adding a new function prototype

libmysqld/lib_sql.cc
- Adding quick conversion method for embedded library:
  conversion is now done directly to result buffer,
  without using a temporary buffer.

mysys/charset.c
- Mark all dynamic ucs2 character sets as non-ASCII
- Mark some dymamic 7bit and 8bit charsets as non-ASCII
  (for example swe7 is not fully ASCII compatible).

sql/protocol.cc
- Adding quick method to convert a string directly
  into protocol buffer, without using a temporary buffer.

sql/protocol.h
- Adding a new method prototype

sql/sql_string.cc
  Optimization for conversion between two ASCII-compatible charsets:
- quickly convert ASCII strings,
  switch to mc_wc->wc_mb method only when a non-ASCII character is met.
- copy four ASCII characters at once on i386

strings/conf_to_src.c
- Marking non-ASCII character sets with a flag.

strings/ctype-extra.c
- Regenerating ctype-extra.c by running "conf_to_src".

strings/ctype-uca.c
- Marking UCS2 character set as non-ASCII.

strings/ctype-ucs2.c
- Marking UCS2 character set as non-ASCII.

strings/ctype.c
- A new function to detect if a 7bit or 8bit character set
  is ascii compatible.

fc1acef6b2 Bug#44521 Executing a stored procedure as a prepared statement can sometimes cause
an assertion in a debug build.

The reason is that the C API doesn't support multiple result sets for prepared
statements and attempting to execute a stored routine which returns multiple result
sets sometimes lead to a network error. The network error sets the diagnostic area
prematurely which later leads to the assert when an attempt is made to set a second
server state.

This patch fixes the issue by changing the scope of the error code returned by
sp_instr_stmt::execute() to include any error which happened during the execution.
To assure that Diagnostic_area::is_sent really mean that the message was sent all
network related functions are checked for return status.

libmysqld/lib_sql.cc:
  * Changed prototype to return success/failure status on net_send_error_packet(),
    net_send_ok(), net_send_eof(), write_eof_packet().

8f500c522b Bug#38522: 5 seconds delay when closing application using embedded server
The problem here is that embedded server starts handle_thread manager 
thread  on mysql_library_init() does not stop it on mysql_library_end().
At shutdown, my_thread_global_end() waits for thread count to become 0,
but since we did not stop the thread it will give up after 5 seconds.
             
Solution is to move shutdown for handle_manager thread from kill_server()
(mysqld specific) to clean_up() that is used by both embedded and mysqld.
            
This patch also contains some refactorings - to avoid duplicate code,
start_handle_manager() and stop_handle_manager() functions are introduced.
Unused variables are eliminated. handle_manager does not rely on global
variable abort_loop anymore to stop (abort_loop is not set for embedded).
            
Note: Specifically on Windows and when using DBUG version of libmysqld, 
the complete solution requires removing obsolete code my_thread_init() 
from my_thread_var(). This has a side effect that a DBUG statement 
after my_thread_end() can cause thread counter to be incremented, and 
embedded will hang for some seconds. Or worse, my_thread_init() will 
crash if critical sections have been deleted by the global cleanup 
routine that runs in a different thread. 

This patch also fixes and revert prior changes for Bug#38293 
"Libmysqld crash in mysql_library_init if language file missing".

Root cause of the crash observed in Bug#38293  was bug in my_thread_init() 
described above




client/mysql.cc:
  sql_protocol_typelib is not exported from libmysqld
  (does not make sense either)
  thus excluded from embedded client
dbug/dbug.c:
  revert changes for Bug#38293
include/my_dbug.h:
  revert changes for Bug#38293
libmysql/libmysql.c:
  Removed DBUG_POP call, because when called after my_end(), will access
  THR_key_mysys that is already deleted. The result of pthread_get_specific
  is not predictable in this case and hence DBUG_POP can crash.
libmysqld/examples/CMakeLists.txt:
  Revert changes for Bug#38293.
libmysqld/lib_sql.cc:
  code to start handle manager is factored out into 
  start_handle_manager() function
libmysqld/libmysqld.def:
  Revert changes for Bug #38293
  Remove excessive exports from libmysqld, export what API documents.
mysys/my_thr_init.c:
  Remove windows-DLL-specific workaround for something (old code, no documentation for
  what specifically). The problem is that even after my_thread_end() is finished, 
  DBUG statement can initiate my_thread_init(). This does not happen anywhere else and 
  should not happen on  Windows either.
sql/mysql_priv.h:
  - new functions start_handle_manager() and stop_handle_manager()
  - move manager_thread_in_use  variable to sql_manager.cc and made
  it static
  - remove manager_status, as it is unused
sql/mysqld.cc:
  Code to start/stop handle_manager thread is factored out into start_handle_manager()

crashed there was no way to obtain a stack trace if no core file
is available. Another problem is that the embedded version of
libmysql was not behaving (crash) the same as the non-embedded with
respect to sending commands to a explicitly closed connection.

The solution is to generate a mysqltest's stack trace on crash
and to enable "reconnect" if the connection handle was explicitly
closed so the behavior matches the non-embedded one.

client/CMakeLists.txt:
  Link mysys to mysqltest.
client/Makefile.am:
  Link mysys to mysqltest.
client/mysqltest.c:
  Add fatal signal handling with backtracing for Unix and Windows.
configure.in:
  Add check for weak symbols support and remove a spurious word.
include/Makefile.am:
  Add new header with prototype for stack tracing functions.
include/my_stacktrace.h:
  Add new header with prototype for stack tracing functions.
libmysqld/CMakeLists.txt:
  stack tracing is now part of mysys.
libmysqld/Makefile.am:
  stack tracing is now part of mysys.
libmysqld/lib_sql.cc:
  Re-connect if connection was explicitly closed. This is
  done to match the behavior of the non-embeded libmysql.
mysql-test/t/sql_low_priority_updates_func.test:
  Test expects parallelism between queries that cannot be
  guaranteed under embedded.
mysys/CMakeLists.txt:
  Add stacktrace to mysys.
mysys/Makefile.am:
  Add stacktrace to mysys.
mysys/stacktrace.c:
  Move stacktrace to mysys and add weak symbol for the
  C++ name de-mangling function so that it can later be
  overridden in C++ code. Also add my_ prefix to exported
  functions.
sql/CMakeLists.txt:
  stacktrace was moved to mysys.
sql/Makefile.am:
  stacktrace was moved to mysys.
sql/mysqld.cc:
  Add my_ prefix to mysys functions.

3703bbf623 Bug#35997 Event scheduler seems to let the server crash, if it is embedded.
SHOW commands fail in embedded mode because schema_table array doesn't
correspond to enum_schema_tables.

This patch implements a dummy implementation of the abstract fill_table
function to be used when the event scheduler (or other core feature)
isn't part of the build.


libmysqld/lib_sql.cc:
  Fixed type conversion warning.
sql/sql_show.cc:
  Leave entry for EVENTS to keep array consistent but set the 
  fill_table function pointer to a dummy function instead.

37a2c4590a Fix broken embedded build (broken by the patch for Bug#12713, first part).
client/mysqltest.c:
  Remove a call to my_message() (server call) in case of a client error.
  It asserts in the embedded build now, since is called after send_ok().
libmysqld/emb_qcache.cc:
  Use net_send_eof (embedded implementation) in embedded query cache/
  send result to client, since send_eof currently does not
  send anything.
libmysqld/emb_qcache.h:
  Declare net_send_eof.
libmysqld/lib_sql.cc:
  Fix the main loop of the embedded server to use the new Diagnostics_area
  API.
sql/log.cc:
  Silence errors of open_performance_schema_table. This function
  is called for general logging, and it happens after the error
  has been sent to the client, and thus triggers an assert.
storage/myisam/ha_myisam.cc:
  Remove an old hack that broke repair.test in embedded build:
  unless we clear an error here, the server attempts to send OK after
  ERROR. This currently asserts.

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.

b88cfbad68 Bug #31868 mysql_server_init crash when language path is not correctly set.
When mysql_server_init() interrupts on some error (wrong errmsg file
for example) in the middle of it's execution, it doesn't call
execute_ddl_log_recovery() so LOCK_gdl mutex isn't init-ed.
In this case we shouldn't execute release_ddl_log during cleanup
as it uses that mutex inside.
