All row lock test with InnoDB have to be executed with the options
--innodb_lock_wait_timeout=1
--innodb_locks_unsafe_for_binlog
for example
perl mysql-test-run.pl --mysqld=--innodb_lock_wait_timeout=2 --mysqld=--innodb_locks_unsafe_for_binlog --suite=row_lock innodb_row_lock_2
Test plan:
Create 2 tables with a primary key and 3 integer columns. Both get the same rows (1,123,1,123),(2,124,2,124),(3,125,3,125),(4,126,4,126). The second and third column may get an index to have cases with, without and mutilple index. Create views on the tables. Create an update trigger. Create a stored procedure updating the table. Create a stored function updating the table and deliver the key as result.
The test isself consists of 2 sessions (transactions) running in "parallel" (same user "root") accessing and locking the same tables on basis of a row lock. Expected is that both sessions(transactions) can update the table successfully.
First session
execute an explain to every select and one of the following selects on the first half of table t1:
- select <non index columns> ... where ... for update;
- select <non index columns> ... where ... lock in share mode;
- select <indexed columns> ... where ... for update;
- select <indexed columns> ... where ... lock in share mode;
- select <indexed columns> ... ignore index ... where ... for update;
- select <indexed columns> ... ignore index ... where ... lock in share mode;
- select ... where (select...) ... for update;
- select ... where (select...) ... lock in share mode;
- (select ... where) union (select ... where) for update;
- (select ... where) union (select ... where) lock in...;
- select <view> ... where ... for update;
- select <view> ... where ... lock in ...;
- select <join> ... where ... for update;
- select <join> ... where ... lock in ...;
Then executes
- update
- delete
- trigger accessing table t1
- stored procedure accessing table t1
- stored function accessing table t1
Second session
executes the same on the last half of table t1
call of mysqld with option
--innodb_locks_unsafe_for_binlog
As the tests above work with small tables (<10 rows) there must be at least one test with a big table (>1000 rows) doing a table scan.

Usage: $0 [OPTIONS]
--basedir=path The path to the MySQL installation directory.
--datadir=path The path to the MySQL data directory.
--force Causes mysql_install_db to run even if DNS does not
work. In that case, grant table entries that normally
use hostnames will use IP addresses.
--ldata=path The path to the MySQL data directory.
--rpm For internal use. This option is used by RPM files
during the MySQL installation process.
--skip-name-resolve Use IP addresses rather than hostnames when creating
grant table entries. This option can be useful if
your DNS does not work.
--srcdir=path For internal use. The directory under which
mysql_install_db looks for support files such as the
error message file and the file for popoulating the
help tables.
--user=user_name The login username to use for running mysqld. Files
and directories created by mysqld will be owned by this
user. You must be root to use this option. By default
