We now reset the THD members related to auto_increment+binlog in
MYSQL_LOG::write(). This is better than in THD::cleanup_after_query(),
which was not able to distinguish between SELECT myfunc1(),myfunc2()
and INSERT INTO t SELECT myfunc1(),myfunc2() from a binlogging point
of view.
Rows_log_event::exec_event() now calls lex_start() instead of
mysql_init_query() because the latter now does too much (it resets
the binlog format).

load data LOCAL INFILE '/tmp/SQL_LOAD_MB-1-2' INTO table t1;
Two INSERT_ID events, useless and a bug. Goes away afer cleaning up
auto_increment handling.
mysql-test/r/rpl_switch_stm_row_mixed.result:
INSERT_ID=5 appears, it's a consequence of having merged the fix
for BUG#20341
"stored function inserting into one auto_increment puts bad data in slave".
In mixed mode, if one substatement of a stored procedure requires row-based,
the entire procedure uses row-based (was already true for stored functions);
this is a consequence of not doing the resetting of binlog format inside
lock_tables() (which didn't work with how the slave thread executes
row-based binlog events).
mysql-test/t/rpl_switch_stm_row_mixed.test:
removing the multi-row delayed insert because in RBR the number of events
which it generates, is not repeatable (probably depends on how the delayed
thread groups rows, i.e. dependent on timing).
sql/ha_partition.cc:
update to new prototype
sql/ha_partition.h:
update to new prototype of the handler:: method.
sql/handler.cc:
after-merge fixes (manually merging part which was hard to merge in fmtool)
sql/log.cc:
When we write to the binary log, THD's parameters which influenced this
write are reset: stmt_depends_on_first_successful_insert_id_in_prev_stmt
and auto_inc_intervals_in_cur_stmt_for_binlog. This is so that future
writes are not influenced by those and can write their own values.
As a consequence, when we don't write to the binlog we do not reset.
This is to abide by the rule that in a complex statement (using triggers etc),
the first top- or substatement to generate auto_increment ids
wins their writing to the binlog (that writing may be done by the statement
itself or by the caller); so for example for
INSERT INTO t SELECT myfunc() where myfunc() inserts into auto_increment
and INSERT INTO t does not, myfunc() will fill
auto_inc_intervals_in_cur_stmt_for_binlog, which will not be reset when
myfunc() ends, then INSERT INTO t will write to the binlog and thus
write the preserved auto_inc_intervals_in_cur_stmt_for_binlog.
sql/log_event.cc:
mysql_init_query() does too much now to be called in Rows_log_event::exec_event
(it call mysql_reset_thd_for_next_command() which may switch
the binlog format now).
It's ok to call it in Table_map_log_event::exec_event() but its call must
be before setting the binlog format to "row".
sql/sql_base.cc:
Resetting the binlog format in lock_tables() was a bad idea of mine;
it causes problems in execution of row-based binlog events, where
the thread sets the binlog format by itself and does not want a next
lock_tables() to reset the binlog format.
It is also misleading, for a function named lock_tables(), to reset
the binlog format.
As a consequence of this change, in mixed binlogging mode, a routine
is logged either entirely statement-based or entirely row-based, we
don't switch in the middle (this was already true for prelocked routines,
now it's also true for stored procedures).
sql/sql_class.cc:
resetting of auto_increment variables used for binlogging is now done
when writing to the binary log, no need to do the resetting at the end
of the statement. It is also more correct this way; consider
SELECT myfunc1(),myfunc2();
where both functions insert into the same auto_increment column.
Binlogging is done in 2 events: "SELECT myfunc1()" and "SELECT myfunc2()".
So each of those needs to have, in binlog, the INSERT_ID which
it inserted. But as the 2 function calls are executed under prelocked mode,
the old code didn't reset auto_inc_intervals_in_cur_stmt_for_binlog
after the first SELECT was binlogged, and so the INSERT_ID of the first
SELECT was binlogged for the first SELECT and (wrong) also for the 2nd
SELECT event.
stmt_depends_on_first_... has the same logic.
sql/sql_class.h:
clearer comment
sql/sql_delete.cc:
unneeded #ifdef. As we temporarily change the binlog format to "statement"
before calling mysql_delete(), we must restore it afterwards.
sql/sql_insert.cc:
after-merge fixes.
No need to reset auto_inc_intervals_in_cur_stmt_for_binlog for every
row in the delayed insert system thread, because we already reset it
when writing to the binlog.

This patch introduces specialized Event data objects
Event_basic as parent.
Event_queue_element used for queue storage
Event_timed used for SHOW EVENTS/ I_S.EVENTS / SHOW CREATE EVENT
Event_job_data using during execution.
Methods were moved out of Event_timed to other classes.
This patch also introduces Events::LOCK_event_metadata.
This patch gives new implementation of Events::dump_internal_status().
Now both the Event_scheduler and Event_queue return information during
their ::dump_internal_status().
Shortened a bit the runtime for executing events test cases.

this is a cleanup patch for our current auto_increment handling:
new names for auto_increment variables in THD, new methods to manipulate them
(see sql_class.h), some move into handler::, causing less backup/restore
work when executing substatements.
This makes the logic hopefully clearer, less work is is needed in
mysql_insert().
By cleaning up, using different variables for different purposes (instead
of one for 3 things...), we fix those bugs, which someone may want to fix
in 5.0 too:
BUG#20339 "stored procedure using LAST_INSERT_ID() does not replicate
statement-based"
BUG#20341 "stored function inserting into one auto_increment puts bad
data in slave"
BUG#19243 "wrong LAST_INSERT_ID() after ON DUPLICATE KEY UPDATE"
(now if a row is updated, LAST_INSERT_ID() will return its id)
and re-fixes:
BUG#6880 "LAST_INSERT_ID() value changes during multi-row INSERT"
(already fixed differently by Ramil in 4.1)
Test of documented behaviour of mysql_insert_id() (there was no test).
The behaviour changes introduced are:
- LAST_INSERT_ID() now returns "the first autogenerated auto_increment value
successfully inserted", instead of "the first autogenerated auto_increment
value if any row was successfully inserted", see auto_increment.test.
Same for mysql_insert_id(), see mysql_client_test.c.
- LAST_INSERT_ID() returns the id of the updated row if ON DUPLICATE KEY
UPDATE, see auto_increment.test. Same for mysql_insert_id(), see
mysql_client_test.c.
- LAST_INSERT_ID() does not change if no autogenerated value was successfully
inserted (it used to then be 0), see auto_increment.test.
- if in INSERT SELECT no autogenerated value was successfully inserted,
mysql_insert_id() now returns the id of the last inserted row (it already
did this for INSERT VALUES), see mysql_client_test.c.
- if INSERT SELECT uses LAST_INSERT_ID(X), mysql_insert_id() now returns X
(it already did this for INSERT VALUES), see mysql_client_test.c.
- NDB now behaves like other engines wrt SET INSERT_ID: with INSERT IGNORE,
the id passed in SET INSERT_ID is re-used until a row succeeds; SET INSERT_ID
influences not only the first row now.
Additionally, when unlocking a table we check that the thread is not keeping
a next_insert_id (as the table is unlocked that id is potentially out-of-date);
forgetting about this next_insert_id is done in a new
handler::ha_release_auto_increment().
Finally we prepare for engines capable of reserving finite-length intervals
of auto_increment values: we store such intervals in THD. The next step
(to be done by the replication team in 5.1) is to read those intervals from
THD and actually store them in the statement-based binary log. NDB
will be a good engine to test that.
mysql-test/extra/binlog_tests/binlog.test:
Testing that if INSERT_ID is set to a value too big for the
column's type, the binlogged INSERT_ID is the truncated value
(important if slave has a column of a "wider" numeric type).
Testing binlogging of INSERT_ID with INSERT DELAYED, to be sure that
we binlog an INSERT_ID event only for the delayed rows which use one.
mysql-test/extra/rpl_tests/rpl_insert_id.test:
Testcase for BUG#20339 "stored procedure using
LAST_INSERT_ID() does not replicate statement-based".
Testcase for BUG#20341 "stored function inserting into one
auto_increment puts bad data in slave".
mysql-test/extra/rpl_tests/rpl_loaddata.test:
Test that LOAD DATA INFILE sets a value for a future LAST_INSERT_ID().
mysql-test/r/auto_increment.result:
behaviour change: when INSERT totally fails (not even succeeds
partially and then rolls back), don't change last_insert_id().
Behaviour change: LAST_INSERT_ID() is now the first successfully inserted,
autogenerated, id.
Behaviour change: if INSERT ON DUPLICATE KEY UPDATE, if the table has auto_increment
and a row is updated, then LAST_INSERT_ID() returns the id of this row.

mysql-test/r/rpl_ndb_auto_inc.result:
ndb's behaviour is now like other engines wrt SET INSERT_ID
in a multi-row INSERT:
- with INSERT IGNORE: the id passed in SET INSERT_ID is re-used until
a row succeeds.
- generally, SET INSERT_ID sets the first value and other values are
simply computed from this first value, instead of previously where
the 2nd and subsequent values where not influenced by SET INSERT_ID;
this good change is due to the removal of "thd->next_insert_id=0"
from ha_ndbcluster.
mysql-test/t/auto_increment.test:
A testcase of BUG#19243: if ON DUPLICATE KEY UPDATE updates a row,
LAST_INSERT_ID() now returns the id of the row.
Test of new behaviour of last_insert_id() when no autogenerated value was
inserted, or when only some autogenerated value (not the first of them) was
inserted.
mysql-test/t/insert.test:
testing INSERT IGNORE re-using generated values
sql/ha_federated.cc:
update for new variables.
sql/ha_ndbcluster.cc:
handler::auto_increment_column_changed not needed, equivalent to
(insert_id_for_cur_row > 0).
thd->next_insert_id=0 not needed anymore; it was used to force
handler::update_auto_increment() to call ha_ndbcluster::get_auto_increment()
for each row of a multi-row INSERT, now this happens naturally
because NDB says "I have reserved you *one* value" in get_auto_increment(),
so handler::update_auto_increment() calls again for next row.
sql/handler.cc:
More comments, use of new methods and variables. Hopes to be clearer
than current code.
thd->prev_insert_id not in THD anymore: it is managed locally by inserters
(like mysql_insert()).
THD::clear_next_insert_id is now equivalent to
handler::next_insert_id > 0.
get_auto_increment() reserves an interval of values from the engine,
uses this interval for next rows of the statement, until interval
is exhausted then it asks for another interval (of a bigger size
than the first one; size doubles until reaching 65535 then it stays constant).
If doing statement-based binlogging, intervals are remembered in a list
for storage in the binlog.
For "forced" insert_id values (SET INSERT_ID or replication slave),
forced_auto_inc_intervals is non-empty and the handler takes its intervals
from there, without calling get_auto_increment().
ha_release_auto_increment() resets the handler's auto_increment variables;
it calls release_auto_increment() which is handler-dependent and
serves to return to the engine any unused tail of the last used
interval.
If ending a statement, next_insert_id>0 means that autoinc values have been
generated or taken from the master's binlog (in a replication slave) so
we clear those values read from binlog, so that next top- or sub-
statement does not use them.
sql/handler.h:
handler::auto_increment_changed can be replaced by
(handler::insert_id_for_cur_row > 0).
THD::next_insert_id moves into handler (more natural, and prepares
for the day when we'll support a single statement inserting into
two tables - "multi-table INSERT" like we have UPDATE - will this
happen?).
This move makes the backup/restore of THD::next_insert_id when entering
a substatement unneeded, as each substatement has its own handler
objects.
sql/item_func.cc:
new names for variables.
For the setting of what mysql_insert_id() will return to the client,
LAST_INSERT_ID(X) used to simply pretend that the generated autoinc
value for the current row was X, but this led to having no reliable
way to know the really generated value, so we now have a bool:
thd->arg_of_last_insert_id_function which enables us to know that
LAST_INSERT_ID(X) was called (and then X can be found in
thd->first_successful_insert_id_in_prev_stmt).
sql/log.cc:
new variable names for insert_ids. Removing some unused variables in the slow
log.
sql/log_event.cc:
new variable names, comments. Preparing for when master's won't binlog
LAST_INSERT_ID if it was 0.
sql/set_var.cc:
new variable names.
The last change repeats how Bar fixed BUG#20392
"INSERT_ID session variable has weird value" in 5.0.
sql/sql_class.cc:
new variables for insert_id. In THD::cleanup_after_query() we fix
BUG#20339 "stored procedure using LAST_INSERT_ID() does not replicate
statement-based" (will one want to fix it in 5.0?). Many comments
about what stored functions do to auto_increment.
In reset|restore_sub_statement_state(), we need to backup less
auto_inc variables as some of them have moved to the handler;
we backup/restore those which are about the current top- or sub-
statement, *not* those about the statement-based binlog
(which evolve as the top- and sub-statement execute).
Because we split THD::last_insert_id into
THD::first_successful_insert_id_in_prev_stmt and
THD::auto_inc_intervals_for_binlog (among others), we fix
BUG#20341 "stored function inserting into one auto_increment
puts bad data in slave": indeed we can afford to not backup/restore
THD::auto_inc_intervals_for_binlog (which fixes the bug) while still
backing up / restoring THD::first_successful_insert_id_in_prev_stmt
(ensuring that the top-level LAST_INSERT_ID() is not affected by INSERTs
done by sub-statements, as is desirable and tested in rpl_insert_id.test).
sql/sql_class.h:
new variables and methods for auto_increment.
Some THD members move into handler (those which are really about
the table being inserted), some stay in THD (those which are
about what a future LAST_INSERT_ID() should return, or about
what should be stored into the statement-based binlog).
THD::next_insert_id moves to handler::.
THD::clear_next_insert_id removed (had become equivalent
to next_insert_id > 0).
THD::last_insert_id becomes four:
THD::first_successful_insert_id_in_cur_stmt,
THD::auto_inc_intervals_for_binlog,
handler::insert_id_for_cur_row,
THD::first_successful_insert_id_in_prev_stmt.
THD::current_insert_id becomes:
THD::first_successful_insert_id_in_prev_stmt_for_binlog
THD::prev_insert_id is removed, handler can just use
handler::insert_id_for_cur_row instead (which is more accurate:
for the first row, prev_insert_id was set before get_auto_increment
was called, so was 0, causing a call to
get_auto_increment() for the 2nd row if the 1st row fails;
here we don't need the call as insert_id_for_cur_row has
the value of the first row).
THD::last_insert_id_used becomes: stmt_depends_on_first_row_in_prev_stmt
THD::insert_id_used is removed (equivalent to
auto_inc_intervals_for_binlog non empty).
The interval returned by get_auto_increment() and currently being
consumed is handler::auto_inc_interval_for_cur_row.
Comments to explain each of them.
select_insert::last_insert_id becomes autoinc_value_of_last_inserted_row.
sql/sql_insert.cc:
the "id" variable is not changed for each row now; it used to compensate for
this contradiction:
- thd->last_insert_id supposed job was to keep the id of the first row
- but it was updated for every row
- so mysql_insert() made sure to catch its first value and restore it at the end of stmt.
Now THD keeps the first value in first_successful_insert_id_in_cur_stmt,
and value of the row in insert_id_for_cur_row. So "id" only serves to fill
mysql_insert_id(), as depending on some conditions, "id" must be different
values.
Prev_insert_id moves from THD to write_record().
We now set LAST_INSERT_ID() in ON DUPLICATE KEY UPDATE too (BUG#19243).
In an INSERT DELAYED, we still "reset auto-increment caching" but differently
(by calling ha_release_auto_increment()).
sql/sql_load.cc:
no need to fiddle with "id", THD maintains
THD::first_successful_insert_id_in_cur_stmt by itself and correctly now.
ha_release_auto_increment() is now (logically) called before we unlock
the table.
sql/sql_parse.cc:
update to new variable names.
Assertion that reset_thd_for_next_command() is not called for every
substatement of a routine (I'm not against it, but if we do this change,
statement-based binlogging needs some adjustments).
sql/sql_select.cc:
update for new variable names
sql/sql_table.cc:
next_insert_id not needed in mysql_alter_table(), THD manages.
sql/sql_update.cc:
update for new variable names.
Even though this is UPDATE, an insert id can be generated (by
LAST_INSERT_ID(X)) and should be recorded because mysql_insert_id() wants
to know about it.

tests/mysql_client_test.c:
tests of behaviour of mysql_insert_id(): there were no such tests, while in
our manual we document its behaviour. In comments you'll notice the behaviour
changes introduced (there are 5).
1) Fix for BUG#19630 "stored function inserting into two auto_increment breaks
statement-based binlog":
a stored function inserting into two such tables may fail to replicate
(inserting wrong data in the slave's copy of the second table) if the slave's
second table had an internal auto_increment counter different from master's.
Because the auto_increment value autogenerated by master for the 2nd table
does not go into binlog, only the first does, so the slave lacks information.
To fix this, if running in mixed binlogging mode, if the stored function or
trigger plans to update two different tables both having auto_increment
columns, we switch to row-based for the whole function.
We don't have a simple solution for statement-based binlogging mode, there
the bug remains and will be documented as a known problem.
Re-enabling rpl_switch_stm_row_mixed.
2) Fix for BUG#20630 "Mixed binlogging mode does not work with stored
functions, triggers, views", which was a documented limitation (in mixed
mode, we didn't detect that a stored function's execution needed row-based
binlogging (due to some UUID() call for example); same for
triggers, same for views (a view created from a SELECT UUID(), and doing
INSERT INTO sometable SELECT theview; would not replicate row-based).
This is implemented by, after parsing a routine's body, remembering in sp_head
that this routine needs row-based binlogging. Then when this routine is used,
the caller is marked to require row-based binlogging too.
Same for views: when we parse a view and detect that its SELECT needs
row-based binary logging, we mark the calling LEX as such.
3) Fix for BUG#20499 "mixed mode with temporary table breaks binlog":
a temporary table containing e.g. UUID has its changes not binlogged,
so any query updating a permanent table with data from the temporary table
will run wrongly on slave. Solution: in mixed mode we don't switch back
from row-based to statement-based when there exists temporary tables.
4) Attempt to test mysqlbinlog on a binlog generated by mysqlbinlog;
impossible due to BUG#11312 and BUG#20329, but test is in place for when
they are fixed.
mysql-test/r/rpl_switch_stm_row_mixed.result:
testing BUG#19630 "stored function inserting into two auto_increment breaks
statement-based binlog",
testing BUG#20930 "Mixed binlogging mode does not work with stored functions,
triggers, views.
testing BUG#20499 "mixed mode with temporary table breaks binlog".
I have carefully checked this big result file, it is correct.
mysql-test/t/disabled.def:
re-enabling test
mysql-test/t/rpl_switch_stm_row_mixed.test:
Test for BUG#19630 "stored function inserting into two auto_increment breaks
statement-based binlog":
we test that it goes row-based, but only when needed;
without the bugfix, master and slave's data differed.
Test for BUG#20499 "mixed mode with temporary table breaks binlog":
without the bugfix, slave had 2 rows, not 3.
Test for BUG#20930 "Mixed binlogging mode does not work with stored
functions, triggers, views".
Making strings used more different, for easier tracking of "by which routine
was this binlog line generated".
Towards the end, an attempt to test mysqlbinlog on a binlog generated by
the mixed mode; attempt failed because of BUG#11312 and BUG#20929.
sql/item_create.cc:
fix for build without row-based replication
sql/set_var.cc:
cosmetic: in_sub_stmt is exactly meant to say if we are in stored
function/trigger, so better use it.
sql/sp.cc:
When a routine adds its tables to the top statement's tables, if this routine
needs row-based binlogging, mark the entire top statement as well.
Same for triggers.
Needed for making the mixed replication mode work with stored functions
and triggers.
sql/sp_head.cc:
new enum value for sp_head::m_flags, remembers if, when parsing the
routine, we found at least one element (UUID(), UDF) requiring row-based
binlogging.
sql/sp_head.h:
new enum value for sp_head::m_flags (see sp_head.cc).
An utility method, intended for attributes of a routine which need
to propagate upwards to the caller; so far only used for binlogging
information, but open to any other attribute.
sql/sql_base.cc:
For BUG#19630 "stored function inserting into two auto_increment
breaks statement-based binlog":
When we come to locking tables, we have collected all tables used by
functions, views and triggers, we detect if we're going to update two tables
having auto_increment columns. If yes, statement-based binlogging won't work
(Intvar_log_event records only one insert_id) so, if in mixed binlogging
mode, switch to row-based.
For making mixed mode work with stored functions using UUID/UDF:
when we come to locking tables, we have parsed the whole body so know if
some elements need row-based. Generation of row-based binlog events
depends on locked tables, so this is the good place to decide of the binlog
format.
sql/sql_class.h:
Fix for BUG#20499 "mixed mode with temporary table breaks binlog".
Making mixed mode work with stored functions/triggers: don't reset
back to statement-based if in executing a stored function/trigger.
sql/sql_lex.cc:
fix for build without row-based replication.
binlog_row_based_if_mixed moves from st_lex to Query_tables_list, because
that boolean should not be affected when a SELECT reads the INFORMATION_SCHEMA
and thus implicitely parses a view or routine's body: this body may
contain needing-row-based components like UUID() but the SELECT on
INFORMATION_SCHEMA should not be affected by that and should not use
row-based; as Query_tables_list is backed-up/reset/restored when parsing
the view/routine's body, so does binlog_row_based_if_mixed and the
top SELECT is not affected.
sql/sql_lex.h:
fix for build without row-based replication.
binlog_row_based_if_mixed moves from st_lex to Query_tables_list
(see sql_lex.cc)
sql/sql_parse.cc:
For the mixed mode to work with stored functions using UUID and UDF, we need
to move the switch-back-from-row-to-statement out of
mysql_execute_command() (which is executed for each statement, causing
the binlogging mode to change in the middle of the function, which would
not work)
The switch to row-based is now done in lock_tables(), no need to keep it
in mysql_execute_command(); in lock_tables() we also switch back from
row-based to statement-based (so in a stored procedure, all statements
have their binlogging mode). We must however keep a resetting in
mysql_reset_thd_for_next_command() as e.g. CREATE PROCEDURE does not call
lock_tables().
sql/sql_view.cc:
When a view's body needs row-based binlogging (e.g. the view is created
from SELECT UUID()), propagate this fact to the top st_lex.
sql/sql_yacc.yy:
use TRUE instead of 1, for binlog_row_based_if_mixed.

Cleaned up the code a bit. Fixed few leaks.
This code still does not load events on server startup
from disk. The problem is that there is a need for a THD instance, which
does not exist during server boot. This will be solved soon.
Still Event_timed is used both for the memory queue and for exectution.
This will be changed according to WL#3337 probably in the next commit.

Strip unneeded stuff from class Event_timed
Event_timed is still used for the queue and execution.

next commit. It will load from disk an instance of Event_job_data to
be used during execution.
sql/event_db_repository.h:
find_event does not need MEM_ROOT anymore
because the memory is allocated on Event's own root.
sql/event_queue.cc:

run at startup"
The server returned an error when trying to execute init-file with a
stored procedure that could return multiple result sets to the client.
A stored procedure can return multiple result sets if it contains
PREPARE, SELECT, SHOW and similar statements.
The fix is to set client_capabilites|=CLIENT_MULTI_RESULTS in
sql_parse.cc:handle_bootstrap(). There is no "client" really, so
nothing is ever sent. This makes init-file feature behave consistently:
the prepared statements that can be called directly in the init-file
can be used in a stored procedure too.
Re-committed the patch originally submitted by Per-Erik after review.

be done in init_file is very limited as it does not support any other
delimiter except ';' -- only "one liners" and no multiple statement
procedures. Also, this is executed with a dummy user "boot@", which
calls for the use of DEFINER clause.

NDB table".
SQL-layer was not marking fields which were used in triggers as such. As
result these fields were not always properly retrieved/stored by handler
layer. So one might got wrong values or lost changes in triggers for NDB,
Federated and possibly InnoDB tables.
This fix solves the problem by marking fields used in triggers
appropriately.
Also this patch contains the following cleanup of ha_ndbcluster code:
We no longer rely on reading LEX::sql_command value in handler in order
to determine if we can enable optimization which allows us to handle REPLACE
statement in more efficient way by doing replaces directly in write_row()
method without reporting error to SQL-layer.
Instead we rely on SQL-layer informing us whether this optimization
applicable by calling handler::extra() method with
HA_EXTRA_WRITE_CAN_REPLACE flag.
As result we no longer apply this optimzation in cases when it should not
be used (e.g. if we have on delete triggers on table) and use in some
additional cases when it is applicable (e.g. for LOAD DATA REPLACE).
Finally this patch includes fix for bug#20728 "REPLACE does not work
correctly for NDB table with PK and unique index".
This was yet another problem which was caused by improper field mark-up.
During row replacement fields which weren't explicity used in REPLACE
statement were not marked as fields to be saved (updated) so they have
retained values from old row version. The fix is to mark all table
fields as set for REPLACE statement. Note that in 5.1 we already solve
this problem by notifying handler that it should save values from all
fields only in case when real replacement happens.
include/my_base.h:
Added HA_EXTRA_WRITE_CAN_REPLACE, HA_EXTRA_WRITE_CANNOT_REPLACE - new
parameters for ha_extra() method. We use them to inform handler that
write_row() which tries to insert new row into the table and encounters
some already existing row with same primary/unique key can replace old
row with new row instead of reporting error.
mysql-test/r/federated.result:
Additional test for bug#18437 "Wrong values inserted with a before update
trigger on NDB table".
mysql-test/r/ndb_replace.result:
Added test for bug #20728 "REPLACE does not work correctly for NDB table
with PK and unique index". Updated wrong results from older test.
mysql-test/t/federated.test:
Additional test for bug#18437 "Wrong values inserted with a before update
trigger on NDB table".
mysql-test/t/ndb_replace.test:
Added test for bug #20728 "REPLACE does not work correctly for NDB table
with PK and unique index".
sql/ha_ndbcluster.cc:
We no longer rely on reading LEX::sql_command value in handler in order
to determine if we can enable optimization which allows us to handle REPLACE
statement in more efficient way by doing replaces directly in write_row()
method without reporting error to SQL-layer.
Instead we rely on SQL-layer informing us whether this optimization
applicable by calling handler::extra() method with
HA_EXTRA_WRITE_CAN_REPLACE flag.
As result we no longer apply this optimization in cases when it should not
be used (e.g. if we have on delete triggers on table) and use in some
additional cases when it is applicable (e.g. for LOAD DATA REPLACE).
sql/item.cc:
Item_trigger_field::setup_field():
Added comment explaining why we don't set Field::query_id in this method.
sql/mysql_priv.h:
mysql_alter_table() function no longer takes handle_duplicates argument.
Added declaration of mark_fields_used_by_triggers_for_insert_stmt() function.
sql/sql_delete.cc:
Mark fields which are used by ON DELETE triggers so handler will retrieve
values for these fields.
sql/sql_insert.cc:
Explicitly inform handler that we are doing REPLACE (using ha_extra() method)
in cases when it can promote insert operation done by write_row() to replace.
Also when we do REPLACE we want to store values for all columns so we should
inform handler about it.
Finally we should mark fields used by ON UPDATE/ON DELETE triggers as such
so handler can properly retrieve/restore values in these fields during
execution of REPLACE and INSERT ... ON DUPLICATE KEY UPDATE statements.
sql/sql_load.cc:
Explicitly inform handler that we are doing LOAD DATA REPLACE (using
ha_extra() method) in cases when it can promote insert operation done by
write_row() to replace.
Also when we do replace we want to save (replace) values for all columns
so we should inform handler about it.
Finally to properly execute LOAD DATA for table with triggers we should
mark fields used by ON INSERT triggers as such so handler can properly
store values for these fields.
sql/sql_parse.cc:
mysql_alter_table() function no longer takes handle_duplicates argument.
sql/sql_table.cc:
Got rid of handle_duplicates argument in mysql_alter_table() and
copy_data_between_tables() functions. These functions were always
called with handle_duplicates == DUP_ERROR and thus contained dead
(and probably incorrect) code.
sql/sql_trigger.cc:
Added Table_triggers_list::mark_fields_used() method which is used to mark
fields read/set by triggers as such so handlers will be able properly
retrieve/store values in these fields.
sql/sql_trigger.h:
Table_triggers_list:
Added mark_fields_used() method which is used to mark fields read/set by
triggers as such so handlers will be able properly retrieve/store values
in these fields. To implement this method added 'trigger_fields' member
which is array of lists linking items for all fields used in triggers
grouped by event and action time.
sql/sql_update.cc:
Mark fields which are used by ON UPDATE triggers so handler will retrieve
and save values for these fields.
mysql-test/r/ndb_trigger.result:

This cut No 7 should finish the part of fixing the parsing of the events :
- Event_timed is no more used during parsing. Less problems because it has
a mutex. Event_parse_data class is used during parsing. It is suited only
for this purpose. It's pretty lightweight
- Late checking of data from parsing is being performed. This should solve
the problems of nested events in SP or other events (for the situation
of no nested bodies). Before if an ALTER EVENT was in a SP, then when the
SP was compiled, and not executed, the actual init_xxx methods of Event_timed
were called, which is wrong.
- It could be a side effect of using a specialized class, but test events_stress is
now 25% quicker.
Cut No8 will start splitting Event_scheduler into 2 parts, the QUEUE will be moved
to Event_queue.

5th cut, moved DB related code to Event_db_repository and
updated accordingly the remanining code.
Moved change/restore_security_context() to class THD
Removed events_priv.h
Next step is to reorganize create/update_event() and parsing for them.
But probably some other refactoring could be done in the meanwhile.
The changes so far pass the test suite.

sql/sql_parse.cc:

Third cut to simplify parsing phase. Now DROP EVENT works.
Overloaded few functions to be able to use either sp_name or pass two LEX_STRINGs
instead of a Event_timed pointer. This is transitional and eventually the old
functions will be removed. For now DROP EVENT also works, does not need anymore
a parsing object (Event_timed) and definer initialization because everyone who
has EVENT_ACL can drop events, and this is checked on execution time in sql_parse.cc
from the security context, as it should be.
sql/event_data_objects.cc:
overload few functions
sql/event_scheduler.cc:
Event_scheduler::drop_event() actually does not need Event_timed object
but just an identifier, hence pass only sp_name.
Overloaded Event_scheduler::find_event() to work with sp_name object. Eventually
the old version will be removed. This is being done as transitional step to
be able to test frequently code.
sql/event_scheduler.h:
Event_scheduler::drop_event() actually does not need Event_timed object
but just an identifier, hence pass only sp_name.
Overloaded Event_scheduler::find_event() to work with sp_name object. Eventually
the old version will be removed. This is being done as transitional step to
be able to test frequently code.
sql/events.cc:
Change db_drop_event() not to use Event_timed, either coming from parsing
or from Event_timed::drop, but use LEX_STRINGs. sp_name is not convinient
because in Event_timed::drop a temporary object has to be created. Hence,
dereference the sp_name in Events::drop_event() and pass the LEX_STRINGs.
sql/events.h:
Change db_drop_event() not to use Event_timed, either coming from parsing
or from Event_timed::drop, but use LEX_STRINGs. sp_name is not convinient
because in Event_timed::drop a temporary object has to be created. Hence,
dereference the sp_name in Events::drop_event() and pass the LEX_STRINGs.
sql/events_priv.h:
Change db_drop_event() not to use Event_timed, either coming from parsing
or from Event_timed::drop, but use LEX_STRINGs. sp_name is not convinient
because in Event_timed::drop a temporary object has to be created. Hence,
dereference the sp_name in Events::drop_event() and pass the LEX_STRINGs.
sql/sql_parse.cc:
SQLCOM_DROP_EVENT does not need lex->event_parse_data object and
is more like SQLCOM_SHOW_CREATE_EVENT. Therefore, move it to the block that
handles the latter.
sql/sql_yacc.yy:
DROP EVENT does not need a parsing object, just a name.
Store it as lex->spname. Pretty similar handling to the one of
SHOW CREATE EVENT.
Second cut of separating parsing phase from execution phase
Separate Event_timed from parsing phase and introducing Event_parse_data.
sql/event_data_objects.cc:
second cut,
copy Event_timed::init_body() to Event_parse_data::init_body()
Init the body during parsing, everything else keep as a pointer to
Item or some other pointer to use for later initialization.
sql/event_data_objects.h:
get the identifier as sp_name*, later will initialize our structures
sql/events.cc:
for easy transition add temporarily parse_data, later Event_timed *et will be removed.
Do slow transition because Event_timed is so tightly integrated that a front-attack
by removing things from this class was unsuccessful. Do things step by step by eliminating
dependencies. Hence, the code could be checked with the current test suite too
(early testing)

Bug#19022 "Memory bug when switching db during trigger execution"
Bug#17199 "Problem when view calls function from another database."
Bug#18444 "Fully qualified stored function names don't work correctly in
SELECT statements"
Documentation note: this patch introduces a change in behaviour of prepared
statements.
This patch adds a few new invariants with regard to how THD::db should
be used. These invariants should be preserved in future:
- one should never refer to THD::db by pointer and always make a deep copy
(strmake, strdup)
- one should never compare two databases by pointer, but use strncmp or
my_strncasecmp
- TABLE_LIST object table->db should be always initialized in the parser or
by creator of the object.
For prepared statements it means that if the current database is changed
after a statement is prepared, the database that was current at prepare
remains active. This also means that you can not prepare a statement that
implicitly refers to the current database if the latter is not set.
This is not documented, and therefore needs documentation. This is NOT a
change in behavior for almost all SQL statements except:
- ALTER TABLE t1 RENAME t2
- OPTIMIZE TABLE t1
- ANALYZE TABLE t1
- TRUNCATE TABLE t1 --
until this patch t1 or t2 could be evaluated at the first execution of
prepared statement.
CURRENT_DATABASE() still works OK and is evaluated at every execution
of prepared statement.
Note, that in stored routines this is not an issue as the default
database is the database of the stored procedure and "use" statement
is prohibited in stored routines.
This patch makes obsolete the use of check_db_used (it was never used in the
old code too) and all other places that check for table->db and assign it
from THD::db if it's NULL, except the parser.
How this patch was created: THD::{db,db_length} were replaced with a
LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were
manually checked and:
- if the place uses thd->db by pointer, it was fixed to make a deep copy
- if a place compared two db pointers, it was fixed to compare them by value
(via strcmp/my_strcasecmp, whatever was approproate)
Then this intermediate patch was used to write a smaller patch that does the
same thing but without a rename.
TODO in 5.1:
- remove check_db_used
- deploy THD::set_db in mysql_change_db

sql/item_strfunc.cc:
Touch the code that reads thd->db (cleanup).
sql/log_event.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.h:
Remove a declaration for a method that is used only in one module.
sql/sp.cc:
Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand
this function and ensure that it has no bugs.
sql/sp.h:
Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment.
sql/sp_head.cc:
- drop sp_name_current_db_new - a creator of sp_name class that was used
when sp_name was created for an identifier without an explicitly initialized
database. Now we pass thd->db to constructor of sp_name right in the
parser.
- rewrite sp_head::init_strings: name->m_db is always set now
- use the new variant of sp_use_new_db
- we don't need to update thd->db with SP MEM_ROOT pointer anymore when
parsing a stored procedure, as noone will refer to it (yes!)
sql/sp_head.h:
- remove unneded methods and members
sql/sql_class.h:
- introduce 3 THD methods to work with THD::db:
.set_db to assign the current database
.reset_db to reset the current database (temporarily) or set it to NULL
.opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL
sql/sql_db.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_insert.cc:
- replace checks with asserts: table_list->db must be always set in the parser.
sql/sql_lex.h:
- add a comment
sql/sql_parse.cc:
- implement the invariant described in the changeset comment.
- remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE:
now db_load_routine uses its own LEX object and doesn't damage the main
LEX.
- add DBUG_ASSERT(0) to unused "check_db_used"
sql/sql_table.cc:
- replace a check with an assert (table_ident->db)
sql/sql_trigger.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_udf.cc:
- use thd->set_db instead of direct modification of to thd->db
sql/sql_view.cc:
- replace a check with an assert (view->db)
sql/sql_yacc.yy:
- make sure that we always copy table->db or name->db or ident->db or
select_lex->db from thd->db if the former is not set. If thd->db
is not set but is accessed, return an error.
sql/tztime.cc:
- be nice, never copy thd->db by pointer.
Addendum fixes after changing the condition variable
for the global read lock.
The stress test suite revealed some deadlocks. Some were
related to the new condition variable (COND_global_read_lock)
and some were general problems with the global read lock.
It is now necessary to signal COND_global_read_lock whenever
COND_refresh is signalled.
We need to wait for the release of a global read lock if one
is set before every operation that requires a write lock.
But we must not wait if we have locked tables by LOCK TABLES.
After setting a global read lock a thread waits until all
write locks are released.
