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:

  header - sql_prepare.h.
sql/procedure.h:
  Rename: Protocol::send_fields() ->

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().

  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().

  Move the declaration of Reprepare_observer to the 
  new header - sql_prepare.h.
  Update to the new signature of class Protocol::send_fields().

  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().

  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() ->

  Add a way to convert a String to LEX_STRING.
sql/sql_table.cc:
  Rename: Protocol::send_fields() -> 
  Protocol::send_result_set_metadata().

  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).

0659b857e7 Bug#27145 EXTRA_ACL troubles
The flag EXTRA_ACL is used in conjugation with our access checks, yet it is
not clear what impact this flag has.
This is a code clean up which replaces use of EXTRA_ACL with an explicit
function parameter.
The patch also fixes privilege checks for:
- SHOW CREATE TABLE: The new privilege requirement is any privilege on
  the table-level.
- CHECKSUM TABLE: Requires SELECT on the table level.
- SHOW CREATE VIEW: Requires SHOW_VIEW and SELECT on the table level
  (just as the manual claims)
- SHOW INDEX: Requires any privilege on any column combination.

  * Error message now shows correct command (SHOW instead of SELECT)
mysql-test/r/grant2.result:
  * Error message now shows correct command (SHOW instead of SELECT)

    and replaced it with a function parameter where any privileges on any column
    combination would satisfy the requirement.
  * Fixed privilege check for SHOW COLUMNS and SHOW INDEX
  * Modified check_table_access to gain clarity in what EXTRA_ACL actually does.
  * Modified check_access to gain clarity in what EXTRA_ACL actually does.

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.

c6b8dcedf9 A fix for Bug#44495 "Prepared Statement: CALL p(<x>) - `thd->protocol == &thd->protocol_text'
failed"

Do not assume that SQL prepared statements always run in text protocol.
When invoked from a stored procedure, which is itself invoked
by means of prepared CALL statement, the protocol may be binary.
Juggle with the protocol only when we want to change it
to binary in COM_STMT_EXECUTE, COM_STMT_PREPARE.

This is a backport from 5.4/6.0, where the bug was fixed
as part of WL#4264 "Backup: Stabilize Service Interface"

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.

7b8bfb2a93 A fix for
Bug#12093 "SP not found on second PS execution if another thread 
drops other SP in between" and
Bug#21294 "executing a prepared statement that executes a stored 
function which was recreat"

Stored functions are resolved at prepared statement prepare only.
If someone flushes the stored functions cache between prepare and
execute, execution fails.

The fix is to detect the situation of the cache flush and automatically
reprepare the prepared statement after it.

02c901ee5e Bug#27430 "Crash in subquery code when in PS and table DDL changed after
PREPARE", review fixes:
- make the patch follow the specification of WL#4166 and remove  
the new error that was originally introduced.
Now the client never gets an error from reprepare, unless it failed.
I.e. even if the statement at hand returns a completely different
result set, this is not considered a server error.
The C API library, that can not handle this situation, was modified to
return a client error.
Added additional test coverage.


include/errmsg.h:
  Add a new client side error: now when we automatically
  reprepare a statement, the new result set may contain a different
  number of columns.
include/mysql_com.h:
  Add a new server status to be sent to the client if the 
  number of columns in the result set is different.
libmysql/errmsg.c:
  Add a new error message.
libmysql/libmysql.c:
  Make the client library robust against a result set that
  contains a different number of columns from prepare time.
  Previously that could never happen, and we simply had an assert.
  That means in particular that all clients are advised to upgrade
  with transition to 5.1, if they are using prepared statements C API.
  Make mysql_stmt_store_result() and mysql_stmt_execute() robust against 
  "broken" statement handles (those that have an error).
sql/sql_parse.cc:
  Clear transient server status flags at start of statement more 
  systematically.
sql/share/errmsg.txt:
  Remove an error that is unused and is not part of any public release.
sql/sql_prepare.cc:
  Instead of returning an error in case the number of result set columns
  has changed, simply update the client in server status.
  That will allow modern clients automatically recover from an error.
tests/mysql_client_test.c:
  Add additional coverage to the cases when the number of result
  set columns changed as a result of reprepare.
  Cover conversion and truncation of result set columns.

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.


mysql-test/r/ps_ddl.result:
  Update test results (WL#4165)
mysql-test/t/ps_ddl.test:
  Cover with tests metadata validation of 26 SQL statements.
sql/mysql_priv.h:
  Fix the name in the comment.
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.
  Add comment to set_parameters().

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.
mysql-test/t/query_cache_merge.test:
  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

cebb6727b3 Bug #26461: Intrinsic data type bool (1 byte) redefined to BOOL (4 bytes)
The bool data type was redefined to BOOL (4 bytes on windows).
Removed the #define and fixed some of the warnings that were uncovered
by this.
Note that the fix also disables 2 warnings :
4800 : 'type' : forcing value to bool 'true' or 'false' (performance warning)
4805: 'operation' : unsafe mix of type 'type' and type 'type' in operation

These warnings will be handled in a separate bug, as they are performance related or bogus.

Fixed to int the return type of functions that return more than 
2 distinct values.

063b504772 Bug#35103 mysql_client_test::test_bug29948 causes sporadic failures
The problem was that the COM_STMT_SEND_LONG_DATA was sending a response
packet if the prepared statement wasn't found in the server (due to
reconnection). The commands COM_STMT_SEND_LONG_DATA and COM_STMT_CLOSE
should not send any packets, even error packets should not be sent since
they are not expected by the client API.

The solution is to clear generated during the execution of the aforementioned
commands and to skip resend of prepared statement commands. Another fix is
that if the connection breaks during the send of prepared statement command,
the command is not sent again since the prepared statement is no longer in the
server.


libmysql/libmysql.c:
  The mysql handle might be reset after a reconnection.
  Pass the now used stmt argument to cli_advanced_command.
sql-common/client.c:
  Don't resend command if the connection broke and it's a prepared
  statement command. If the session is broken, prepared statements
  on the server are gone, set the error accordanly.
sql/sql_prepare.cc:
  Clear any error set during the execution of the request
  command.
tests/mysql_client_test.c:
  Fix memory leak by freeing result associated with statement.
  Remove test case for Bug 29948 because it's not reliable in
  5.0 (fixed in 5.1) due to KILL queries sending two packets for
  a thread that kills itself.

315665cf67 Bug#32890 Crash after repeated create and drop of tables and views
The problem is that CREATE VIEW statements inside prepared statements
weren't being expanded during the prepare phase, which leads to objects
not being allocated in the appropriate memory arenas.

The solution is to perform the validation of CREATE VIEW statements
during the prepare phase of a prepared statement. The validation
during the prepare phase assures that transformations of the parsed
tree will use the permanent arena of the prepared statement.
