gets deadlocked when dropping w/ log on"
Log tables rely on concurrent insert machinery to add data.
This means that log tables are always opened and locked by
special (artificial) logger threads. Because of this, the thread
which tries to drop a log table starts to wait for the table
to be unlocked. Which will happen only if the log table is disabled.
Alike situation happens if one tries to alter a log table.
However in addition to the problem above, alter table calls
check_if_locking_is_allowed() routine for the engine. The
routine does not allow alter for the log tables. So, alter
doesn't start waiting forever for logs to be disabled, but
returns with an error.
Another problem is that not all engines could be used for
the log tables. That's because they need concurrent insert.
In this patch we:
(1) Explicitly disallow to drop/alter a log table if it
is currently used by the logger.
(2) Update MyISAM to support log tables
(3) Allow to drop log tables/alter log tables if log is
disabled
At the same time we (4) Disallow to alter log tables to
unsupported engine (after this patch CSV and MyISAM are
alowed)
Recommit with review fixes.
mysql-test/r/log_tables.result:
Update result file.
Note: there are warnings in result file. This is because of CSV
bug (Bug #21328). They should go away after it is fixed.
mysql-test/t/log_tables.test:
Add a test for the bug
sql/ha_myisam.cc:
Add log table handling to myisam: as log tables
use concurrent insert, they are typically
locked with TL_CONCURRERENT_INSERT lock. So,
disallow other threads to attempt locking of
the log tables in incompatible modes. Because
otherwise the threads will wait for the tables
to be unlocked forever.
sql/handler.cc:
Add a function to check if a table we're going to lock
is a log table and if the lock mode we want allowed
sql/handler.h:
Add a new function to check compatibility of the locking
sql/log.cc:
we shouldn't close the log table if and only
if this particular table is already closed
sql/log.h:
add new functions to check if a log is enabled
sql/share/errmsg.txt:
add new error messages
sql/sql_table.cc:
DROP and ALTER TABLE should not work on log
tables if the log tables are enabled
storage/csv/ha_tina.cc:
move function to check if the locking for the log
tables allowed to handler class, so that we can
reuse it in other engines.

storage/myisam/mi_write.c:
update status after each write if it's a log table
storage/myisam/myisamdef.h:
Add new log table flag to myisam share.
We need it to distinguish between usual
and log tables, as for the log tables we
should provide concurrent insert in a
different way than for usual tables: we
want new rows to be immediately visible
to other threads.

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/binlog_row_binlog.result:
result update

mysql-test/r/rpl_insert_id.result:

mysql-test/r/rpl_loaddata.result:

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).
this is a cleanup patch for our current auto_increment handling:
new names for auto_increment variables in THD, new methods to manipulate them

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.
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).

This change allows us to use the stmt_binlog function in the code without ifdefs
(We should avoid having ifdefs in the .cc and .c files)
