Extended syntax so that it is now possible to set lock_wait_timeout for the
following statements:
SELECT ... FOR UPDATE [WAIT n|NOWAIT]
SELECT ... LOCK IN SHARED MODE [WAIT n|NOWAIT]
LOCK TABLE ... [WAIT n|NOWAIT]
CREATE ... INDEX ON tbl_name (index_col_name, ...) [WAIT n|NOWAIT] ...
ALTER TABLE tbl_name [WAIT n|NOWAIT] ...
OPTIMIZE TABLE tbl_name [WAIT n|NOWAIT]
DROP INDEX ... [WAIT n|NOWAIT]
TRUNCATE TABLE tbl_name [WAIT n|NOWAIT]
RENAME TABLE tbl_name [WAIT n|NOWAIT] ...
DROP TABLE tbl_name [WAIT n|NOWAIT] ...
Valid range of lock_wait_timeout and innodb_lock_wait_timeout was extended so
that 0 is acceptable value (means no wait).
This is amended AliSQL patch. We prefer Oracle syntax for [WAIT n|NOWAIT]
instead of original [WAIT [n]|NO_WAIT].
- Second scenario checked:
Ensure via wait routines that the commit comes after the
processing of the statement which should get finally
the ER_LOCK_WAIT_TIMEOUT
--> This should prevent the current bug.
- First scenario checked:
Ensure via wait routines that the statement is already waiting
for getting the lock before the commit is given.
--> No effect on the current bug, but ensure that the right
scenario is reached.
- Take care that disconnects are finished before the test ends.
--> Reduce the potential to harm succeeding tests.
- "Mangle" the printout of the current default innodb_lock_wait_timeout value
--> No need to adjust the test in case the default gets changed in future.
Created a test suite 'innodb' under mysql-test/suite/innodb for the innodb plugin tests.
test suite 'innodb' has tests only which are not under any other mysql-test suites.
Total 14 testcases are added to the test suite.
Note: the patches in storage/innodb_plugin/mysql-test/patches are not applied yet
