Bug 18914 (Calling certain SPs from triggers fail)
Bug 20713 (Functions will not not continue for SQLSTATE VALUE '42S02')
Bug 21825 (Incorrect message error deleting records in a table with a
trigger for inserting)
Bug 22580 (DROP TABLE in nested stored procedure causes strange dependency
error)
Bug 25345 (Cursors from Functions)
This fix resolves a long standing issue originally reported with bug 8407,
which affect the behavior of Stored Procedures, Stored Functions and Trigger
in many different ways, causing symptoms reported by all the bugs listed.
In all cases, the root cause of the problem traces back to 8407 and how the
server locks tables involved with sub statements.
Prior to this fix, the implementation of stored routines would:
- compute the transitive closure of all the tables referenced by a top level
statement
- open and lock all the tables involved
- execute the top level statement
"transitive closure of tables" means collecting:
- all the tables,
- all the stored functions,
- all the views,
- all the table triggers
- all the stored procedures
involved, and recursively inspect these objects definition to find more
references to more objects, until the list of every object referenced does
not grow any more.
This mechanism is known as "pre-locking" tables before execution.
The motivation for locking all the tables (possibly) used at once is to
prevent dead locks.
One problem with this approach is that, if the execution path the code
really takes during runtime does not use a given table, and if the table is
missing, the server would not execute the statement.
This in particular has a major impact on triggers, since a missing table
referenced by an update/delete trigger would prevent an insert trigger to run.
Another problem is that stored routines might define SQL exception handlers
to deal with missing tables, but the server implementation would never give
user code a chance to execute this logic, since the routine is never
executed when a missing table cause the pre-locking code to fail.
With this fix, the internal implementation of the pre-locking code has been
relaxed of some constraints, so that failure to open a table does not
necessarily prevent execution of a stored routine.
In particular, the pre-locking mechanism is now behaving as follows:
1) the first step, to compute the transitive closure of all the tables
possibly referenced by a statement, is unchanged.
2) the next step, which is to open all the tables involved, only attempts
to open the tables added by the pre-locking code, but silently fails without
reporting any error or invoking any exception handler is the table is not
present. This is achieved by trapping internal errors with
Prelock_error_handler
3) the locking step only locks tables that were successfully opened.
4) when executing sub statements, the list of tables used by each statements
is evaluated as before. The tables needed by the sub statement are expected
to be already opened and locked. Statement referencing tables that were not
opened in step 2) will fail to find the table in the open list, and only at
this point will execution of the user code fail.
5) when a runtime exception is raised at 4), the instruction continuation
destination (the next instruction to execute in case of SQL continue
handlers) is evaluated.
This is achieved with sp_instr::exec_open_and_lock_tables()
6) if a user exception handler is present in the stored routine, that
handler is invoked as usual, so that ER_NO_SUCH_TABLE exceptions can be
trapped by stored routines. If no handler exists, then the runtime execution
will fail as expected.
With all these changes, a side effect is that view security is impacted, in
two different ways.
First, a view defined as "select stored_function()", where the stored
function references a table that may not exist, is considered valid.
The rationale is that, because the stored function might trap exceptions
during execution and still return a valid result, there is no way to decide
when the view is created if a missing table really cause the view to be invalid.
Secondly, testing for existence of tables is now done later during
execution. View security, which consist of trapping errors and return a
generic ER_VIEW_INVALID (to prevent disclosing information) was only
implemented at very specific phases covering *opening* tables, but not
covering the runtime execution. Because of this existing limitation,
errors that were previously trapped and converted into ER_VIEW_INVALID are
not trapped, causing table names to be reported to the user.
This change is exposing an existing problem, which is independent and will
be resolved separately.

Before this fix, the function BENCHMARK() would fail to evaluate expressions
like "(select avg(a) from t1)" in debug builds (with an assert),
or would report a time of zero in non debug builds.
The root cause is that evaluation of DECIMAL_RESULT expressions was not
supported in Item_func_benchmark::val_int().
This has been fixed by this change.

This patch fixes problem that LOAD DATA could use different
character sets when loading files on master and on slave sides:
- Adding replication of thd->variables.collation_database
- Adding optional character set clause into LOAD DATA
Note, the second way, with explicit CHARACTER SET clause
should be the recommended way to load data using an alternative
character set.
The old way, using "SET @@character_set_database=xxx" should be
gradually depricated.

SF/Triggers in SBR mode."
BUG#14914 "SP: Uses of session variables in routines are not always replicated"
BUG#25167 "Dupl. usage of user-variables in trigger/function is not replicated
correctly"
User-defined variables used inside of stored functions/triggers in
statements which did not update tables directly were not replicated.
We also had problems with replication of user-defined variables which
were used in triggers (or stored functions called from table-updating
statements) more than once.
This patch addresses the first issue by enabling logging of all
references to user-defined variables in triggers/stored functions
and not only references from table-updating statements.
The second issue stemmed from the fact that for user-defined
variables used from triggers or stored functions called from
table-updating statements we were writing binlog events for each
reference instead of only one event for the first reference.
This problem is already solved for stored functions called from
non-updating statements with help of "event unioning" mechanism.
So the patch simply extends this mechanism to the case affected.
It also fixes small problem in this mechanism which caused wrong
logging of references to user-variables in cases when non-updating
statement called several stored functions which used the same
variable and some of these function calls were omitted from binlog
as they were not updating any tables.

sql/item_func.cc:
BUG#20141 - User-defined variables are not replicated properly for SF/Triggers
in SBR mode.
To properly log accesses to user-defined variables from stored
functions/triggers, the get_var_with_binlog() method needs to log references
to such variables even from non-table-updating statements within them.
sql/log.cc:
BUG#20141 - User-defined variables are not replicated properly for SF/Triggers
in SBR mode.
This patch modifies the start_union_events method to accept the query id from
a parameter. This allows callers to set the query_id to the id of the sub
statement such as a trigger or stored function. Which permits the code to
identify when a user defined variable has been used by the statement and this
already present in THD::user_var_event.
Note:
The changes to sql_class.cc, sp_head.cc, and log.cc are designed to allow the
proper replication of access to user-defined variables under a special test
case (the last case shown in rpl_user_variables.test).

to set the start of the events.

mysqlbinlog prints all row-based events of a single statement as a
single "BINLOG" statement containing the concatenation of those events.
Big (i.e. >64k) concatenations of row-based events
(e.g. Write_rows_log_event) caused mysqlbinlog's IO_CACHE to overflow
to a temporary file but the IO_CACHE had not been inited with
open_cached_file(), so it tried to create a temporary file in
an uninitialized directory (thus failing to create, then to write;
some OS errors were printed, and it finally segfaulted).
After fixing this, it appeared that mysqlbinlog was printing only
a piece of big concatenations of row-based events (it printed
at most the size of the IO_CACHE's buffer i.e. 64k); that caused data
loss at restore. We fix and test that.
Last, mysqlbinlog's printouts looked a bit strange with the informative
header (#-prefixed) of groupped Rows_log_event all on one line,
so we insert \n. After that, a small bug in the --hexdump code appeared
(only if the string to hex-print had its length a multiple of 16),
we fix it.
client/mysqlbinlog.cc:
if we write to IO_CACHE more than can fit into its memory buffer,
it will try to overflow into a file; for that to work, IO_CACHE
must be inited via open_cached_file().
mysql-test/r/mysqlbinlog_base64.result:

mysql-test/t/mysqlbinlog_base64.test:
test for BUG#25628: test that mysqlbinlog does not have OS errors
with big concatenations of row-based events
(e.g. Write_rows_log_event), and prints those concatenations entirely
(testing by piping the output back into the server and comparing data).
mysys/mf_iocache2.c:
my_b_copy_to_file() had a problem: it assumed that bytes_in_cache
are all the bytes to copy to the file, while it only tells how many
bytes are in the buffer; so the code forgot to copy what had already
overflown into a temporary file. Thus any big event was printed only
partially by mysqlbinlog (loss of data at restore). The fix is
inspired by MYSQL_BIN_LOG::write_cache().
sql/log_event.cc:
Several Table_map/Write_rows events generated by one single statement
get groupped together in mysqlbinlog's output; it printed things like
#718 7:30:51 server id 12 end_log_pos 988 Write_rows: table id 17#718 7:30:51 server id 12 #718 7:30:51 server id 12 end_log_pos 988 Write_rows: table id 17#718 7:30:51 server id 12 end_log_pos 1413 <cut>
It didn't look nice to have printouts glued like this without line
breaks. Adding a line break.
Doing this, when using --hexdump the result was:
#718 7:30:51 server id 12 end_log_pos 988
# <hexdump output>
# Write_rows: table id 17
which is correct; unfortunately if the hex dump had only full lines
(i.e the string to print in hex had its length a multiple of 16),
then the # in front of Write_rows was not printed. Fixed.

removing strcpy() (one less function call).
If we write to IO_CACHE more than can fit into its memory buffer,
it will try to overflow into a file; for that to work, IO_CACHE
must be inited via open_cached_file().
open_cached_file(), like init_io_cache(), can fail; we make sure to
catch this constructor's problem via the init_ok() method.

BUG#14914 "SP: Uses of session variables in routines are not always
replicated"
BUG#25167 "Dupl. usage of user-variables in trigger/function is not
replicated correctly"
User-defined variables used inside of stored functions/triggers in
statements which did not update tables directly were not replicated.
We also had problems with replication of user-defined variables which
were used in triggers (or stored functions called from table-updating
statements) more than once.
This patch addresses the first issue by enabling logging of all
references to user-defined variables in triggers/stored functions
and not only references from table-updating statements.
The second issue stemmed from the fact that for user-defined
variables used from triggers or stored functions called from
table-updating statements we were writing binlog events for each
reference instead of only one event for the first reference.
This problem is already solved for stored functions called from
non-updating statements with help of "event unioning" mechanism.
So the patch simply extends this mechanism to the case affected.
It also fixes small problem in this mechanism which caused wrong
logging of references to user-variables in cases when non-updating
statement called several stored functions which used the same
variable and some of these function calls were omitted from binlog
as they were not updating any tables.
mysql-test/r/rpl_user_variables.result:
BUG#20141 - User-defined variables are not replicated properly for SF/Triggers in SBR mode.
This patch adds the correct results for execution of the added test procedures to the
rpl_user_variables test.
mysql-test/t/rpl_user_variables.test:
BUG#20141 - User-defined variables are not replicated properly for SF/Triggers in SBR mode.
This patch adds additional tests to the rpl_user_variables test that test many of the
different ways user-defined variables can be required to be replicated.
sql/item_func.cc:
BUG#20141 - User-defined variables are not replicated properly for SF/Triggers in SBR mode.
To properly log accesses to user-defined variables from stored functions/triggers,
the get_var_with_binlog() method needs to log references to such variables even from
non-table-updating statements within them.
sql/log.cc:
BUG#20141 - User-defined variables are not replicated properly for SF/Triggers in SBR mode.
This patch modifies the start_union_events method to accept the query id from a parameter.
This allows callers to set the query_id to the id of the sub statement such as a trigger
or stored function. Which permits the code to identify when a user defined variable has
been used by the statement and this already present in THD::user_var_event.
Note:
The changes to sql_class.cc, sp_head.cc, and log.cc are designed to allow the proper
replication of access to user-defined variables under a special test case (the last case
shown in rpl_user_variables.test).
sql/sp_head.cc:
BUG#20141 - User-defined variables are not replicated properly for SF/Triggers in SBR mode.
This patch modifies the code to allow for cases where events for function calls have
a separate union for each event and thus cannot use the query_id of the caller as the
start of the union. Thus, we use an artifically created query_id to set the start of
the events.
Note:
The changes to sql_class.cc, sp_head.cc, and log.cc are designed to allow the proper
replication of access to user-defined variables under a special test case (the last case
shown in rpl_user_variables.test).
sql/sql_class.cc:
BUG#20141 - User-defined variables are not replicated properly for SF/Triggers in SBR mode.
This patch adds the query_id parameter to the calls to mysql_bin_log.start_union_events().
Note:
The changes to sql_class.cc, sp_head.cc, and log.cc are designed to allow the proper
replication of access to user-defined variables under a special test case (the last case

sql/sql_class.h:
BUG#20141 - User-defined variables are not replicated properly for SF/Triggers in SBR mode.
This patch adds the query_id parameter to the calls to mysql_bin_log.start_union_events().
