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a next_insert_id (as the table is unlocked that id is potentially out-of-date);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.
sql/structs.h:
A class for "discrete" intervals (intervals of integer numbers with a certain
increment between them): Discrete_interval, and a class for a list of such
intervals: Discrete_intervals_list
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:

I have carefully checked this big result file, it is correct.
mysql-test/t/disabled.def:

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.

The bug was that if the server was running in mixed binlogging mode,
and an INSERT DELAYED used some needing-row-based components like UUID(),
the server didn't binlog this row-based but statement-based, which
thus failed to insert correct data on the slave.
This changeset implements that when a delayed_insert thread is created,
if the server's global binlog mode is "mixed", that thread will use row-based.
This also fixes BUG#20633 "INSERT DELAYED RAND() or @user_var does not
replicate statement-based": we don't fix it in statement-based mode (would
require bookeeping of rand seeds and user variables used by each row),
but at least it will now work in mixed mode (as row-based will be used).
We re-enable rpl_switch_stm_row_mixed.test (so BUG#18590
which was about re-enabling this test, will be closed) to test the fixes.
Between when it was disabled and now, some good changes to row-based
binlogging (no generation of table map events for non-changed tables)
induce changes in the test's result file.
mysql-test/r/rpl_switch_stm_row_mixed.result:
result update.
Note that some pieces of binlog are gone, not due to my test but to changes
to the row-based binlogging code (non-changed tables don't generate
table map binlog events now) done while the test was disabled.
mysql-test/t/disabled.def:
this test works now
mysql-test/t/rpl_switch_stm_row_mixed.test:
testing fix to make INSERT DELAYED work in mixed mode
sql/sql_insert.cc:
In mixed binlogging mode, the delayed_insert system thread now always
uses row-based binlogging.
This makes replication of INSERT DELAYED VALUES(RAND()) or VALUES(@a)
work in mixed mode (it does not in statement-based).
a too large value": the bug was that if MySQL generated a value for an
auto_increment column, based on auto_increment_* variables, and this value
was bigger than the column's max possible value, then that max possible
value was inserted (after issuing a warning). But this didn't honour
auto_increment_* variables (and so could cause conflicts in a master-master
replication where one master is supposed to generated only even numbers,
and the other only odd numbers), so now we "round down" this max possible
value to honour auto_increment_* variables, before inserting it.
mysql-test/r/rpl_auto_increment.result:
result update. Before the fix, the result was that master inserted 127 in t1
(which didn't honour auto_increment_* variables!),
instead of failing with "duplicate key 125" like now.
mysql-test/t/rpl_auto_increment.test:
Test for BUG#20524 "auto_increment_* not observed when inserting
a too large value".
We also check the pathological case (table t2) where it's impossible to
"round down".
The fixer of BUG#20573 will be able to use table t2 for testing his fix.
sql/handler.cc:
If handler::update_auto_increment() generates a value larger than the field's
max possible value, we used to simply insert this max possible value
(after pushing a warning). Now we "round down" this max possible value to
honour auto_increment_* variables (if at all possible), before trying the
insertion.

auto_increment breaks binlog":
if slave's table had a higher auto_increment counter than master's (even
though all rows of the two tables were identical), then in some cases,
REPLACE and INSERT ON DUPLICATE KEY UPDATE failed to replicate
statement-based (it inserted different values on slave from on master).
write_record() contained a "thd->next_insert_id=0" to force an adjustment
of thd->next_insert_id after the update or replacement. But it is this
assigment introduced indeterminism of the statement on the slave, thus
the bug. For ON DUPLICATE, we replace that assignment by a call to
handler::adjust_next_insert_id_after_explicit_value() which is deterministic
(does not depend on slave table's autoinc counter). For REPLACE, this
assignment can simply be removed (as REPLACE can't insert a number larger
than thd->next_insert_id).
We also move a too early restore_auto_increment() down to when we really know
that we can restore the value.
mysql-test/r/rpl_insert_id.result:
result update, without the bugfix, slave's "3 350" were "4 350".
mysql-test/t/rpl_insert_id.test:
test for BUG#20188 "REPLACE or ON DUPLICATE KEY UPDATE in
auto_increment breaks binlog".
There is, in this order:
- a test of the bug for the case of REPLACE
- a test of basic ON DUPLICATE KEY UPDATE functionality which was not
tested before
- a test of the bug for the case of ON DUPLICATE KEY UPDATE
sql/handler.cc:
the adjustment of next_insert_id if inserting a big explicit value, is
moved to a separate method to be used elsewhere.
sql/handler.h:
see handler.cc
sql/sql_insert.cc:
restore_auto_increment() means "I know I won't use this autogenerated
autoincrement value, you are free to reuse it for next row". But we were
calling restore_auto_increment() in the case of REPLACE: if write_row() fails
inserting the row, we don't know that we won't use the value, as we are going to
try again by doing internally an UPDATE of the existing row, or a DELETE
of the existing row and then an INSERT. So I move restore_auto_increment()
further down, when we know for sure we failed all possibilities for the row.
Additionally, in case of REPLACE, we don't need to reset THD::next_insert_id:
the value of thd->next_insert_id will be suitable for the next row.
In case of ON DUPLICATE KEY UPDATE, resetting thd->next_insert_id is also
wrong (breaks statement-based binlog), but cannot simply be removed, as
thd->next_insert_id must be adjusted if the explicit value exceeds it.
We now do the adjustment by calling
handler::adjust_next_insert_id_after_explicit_value() (which, contrary to
thd->next_insert_id=0, does not depend on the slave table's autoinc counter,
and so is deterministic).

mysql-test/r/key.result:
Fixed result after removing wrong bug fix
sql/table.cc:
Reverted wrong bug fix.
The intention with the original code was to show that MySQL treats the first
given unique key as a primary key. Clients can use the marked primary key as a
real primary key to validate row changes in case of conflicting updates. The
ODBC driver (and other drivers) may also use this fact to optimize/check
updates and handle conflicts. The marked key also shows what some engines, like InnoDB or NDB,
will use as it's internal primary key.
For checking if someone has declared a true PRIMARY KEY, one should use 'SHOW CREATE TABLE'
