d15cbc1a1a Bug #40745: Error during WHERE clause calculation in UPDATE
leads to an assertion failure

Any run-time error in stored function (like recursive function
call or update of table that is already updating by statement
which invoked this stored function etc.) that was used in some
expression of the single-table UPDATE statement caused an
assertion failure.
Multiple-table UPDATE (as well as INSERT and both single- and
multiple-table DELETE) are not affected.

  The mysql_update function has been updated to take into account
  the status of invoked stored functions before setting the status
  of whole UPDATE query to OK.

a83f5b18ef Bug#38499: flush tables and multitable table update with
derived table cause crash

When a multi-UPDATE command fails to lock some table, and
subsequently succeeds, the tables need to be reopened if
they were altered. But the reopening procedure failed for
derived tables.

Extra cleanup has been added.

f48b42e776 Bug #38691: segfault/abort in ``UPDATE ...JOIN'' while
``FLUSH TABLES WITH READ LOCK''

Concurrent execution of 1) multitable update with a
NATURAL/USING join and 2) a such query as "FLUSH TABLES
WITH READ LOCK" or "ALTER TABLE" of updating table led
to a server crash.


The mysql_multi_update_prepare() function call is optimized
to lock updating tables only, so it postpones locking to
the last, and if locking fails, it does cleanup of modified
syntax structures and repeats a query analysis.  However,
that cleanup procedure was incomplete for NATURAL/USING join
syntax data: 1) some Field_item items pointed into freed
table structures, and 2) the TABLE_LIST::join_columns fields
was not reset.

Major change:
  short-living Field *Natural_join_column::table_field has
  been replaced with long-living Item*.

  2) The setup_natural_join_row_types function has been

     reinitialization of Natural_join_column::join_columns
     during table reopening after lock_tables() failure

0406d409ea Bug#34306: Can't make copy of log tables when server binary log is enabled
The problem is that when statement-based replication was enabled,
statements such as INSERT INTO .. SELECT FROM .. and CREATE TABLE
.. SELECT FROM need to grab a read lock on the source table that
does not permit concurrent inserts, which would in turn be denied
if the source table is a log table because log tables can't be
locked exclusively.

The solution is to not take such a lock when the source table is
a log table as it is unsafe to replicate log tables under statement
based replication. Furthermore, the read lock that does not permits
concurrent inserts is now only taken if statement-based replication
is enabled and if the source table is not a log table.

include/thr_lock.h:
  Introduce yet another lock type that my get upgraded depending
  on the binary log format. This is not a optimal solution but
  can be easily improved later.

sql/sql_base.cc:
  Introduce function that returns the appropriate read lock type
  depending on how the statement is going to be replicated. It will
  only take a TL_READ_NO_INSERT log if the binary is enabled and the
  binary log format is statement-based and the table is not a log table.
sql/sql_parse.cc:
  Remove using_update_log.
sql/sql_update.cc:
  Use new function to choose read lock type.
sql/sql_yacc.yy:
  The lock type is now decided at open_tables time. This old behavior was
  actually misleading as the binary log format can be dynamically switched
  and this would not change for statements that have already been parsed
  when the binary log format is changed (ie: prepared statements).

29e7fa258d Fixed bug#36676: multiupdate using LEFT JOIN updates only
first row or fails with an error:
  ERROR 1022 (23000): Can't write; duplicate key in table ''

The server uses intermediate temporary table to store updated
row data.  The first column of this table contains rowid.
Current server implementation doesn't reset NULL flag of that
column even if the server fills a column with rowid.
To keep each rowid unique, there is an unique index.
An insertion into an unique index takes into account NULL
flag of key value and ignores real data if NULL flag is set.
So, insertion of actually different rowids may lead to two
kind of problems.  Visible effect of each of these problems
depends on an initial engine type of temporary table:

1. If multiupdate initially creates temporary table as
a MyISAM table (a table contains blob columns, and the
create_tmp_table function assumes, that this table is
large), it inserts only one single row and updates
only rows with one corresponding rowid. Other rows are
silently ignored. 

2. If multiupdate initially creates MEMORY temporary
table, fills it with data and reaches size limit for
MEMORY tables (max_heap_table_size), multiupdate
converts MEMORY table into MyISAM table and fails
with an error:
  ERROR 1022 (23000): Can't write; duplicate key in table ''


Multiupdate has been fixed to update the NULL flag of
temporary table rowid columns.

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.

1626b42ca3 BUG#34768 - nondeterministic INSERT using LIMIT logged in stmt mode if
binlog_format=mixed

Statement-based replication of DELETE ... LIMIT, UPDATE ... LIMIT,
INSERT ... SELECT ... LIMIT is not safe as order of rows is not
defined.

With this fix, we issue a warning that this statement is not safe to
replicate in statement mode, or go to row-based mode in mixed mode.

Note that we may consider a statement as safe if ORDER BY primary_key
is present. However it may confuse users to see very similiar statements
replicated differently.

Note 2: regular UPDATE statement (w/o LIMIT) is unsafe as well, but
this patch doesn't address this issue. See comment from Kristian

The idea of the fix is to ensure that we always commit the current

redundant disc syncs, an optimization of the two-phase commit

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/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:

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

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

8d51c6ad68 Bug#23771 AFTER UPDATE trigger not invoked when there are no changes of the data
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).

6210278628 Bug#33329 extraneous ROLLBACK in binlog on connection
does not use trans tables

There had been two issues.
Rollback statement was recorded in binlog even though a multi-update
had not modified any non-transactional table.
The reason for this artifact was a false initial value of multi_update::transactional_tables.
Yet another artifact that explained on the bug page is that 
`ha_autocommit_or_rollback' works differently depending on whether
a transaction engine has been compiled in. 

Fixed: with setting multi_update::transactional_tables to zero at initialization
time. Multi-update on non-trans table won't cause ROLLBACK in binlog with
either compilation option.

The 2nd mentioned artifact comprises a self-standing issue (to be reported
separately).


mysql-test/r/multi_update.result:
  results changed - there is no ROLLBACK in binlog anymore as it should be
sql/sql_update.cc:
  A wrong assumption on that there were modified transactional table,
  which is nonsense at the very beginning of the query execution.

0fbc29c197 A pre-requisite for the fix for Bug#12713 "Error in a stored function
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.

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.

95f3db7be1 Bug #27571 asynchronousity in setting mysql_query::error and
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.
