Part of fix for bug#52044 "FLUSH TABLES WITH READ LOCK and
FLUSH TABLES <list> WITH READ LOCK are incompatible" to
be pushed as separate patch.
Replaced thread state name "Waiting for table", which was
used by threads waiting for a metadata lock or table flush,
with a set of names which better reflect types of resources
being waited for.
Also replaced "Table lock" thread state name, which was used
by threads waiting on thr_lock.c table level lock, with more
elaborate "Waiting for table level lock", to make it
more consistent with other thread state names.
Updated test cases and their results according to these
changes.
Fixed sys_vars.query_cache_wlock_invalidate_func test to not
to wait for timeout of wait_condition.inc script.
mysql-test/r/query_cache.result:
Added test coverage for query_cache_wlock_invalidate
behavior for implicitly locked tables.
mysql-test/suite/sys_vars/r/query_cache_wlock_invalidate_func.result:
Fixed sys_vars.query_cache_wlock_invalidate_func test to not
to wait for timeout of wait_condition.inc script. Reverted
changes to test which introduced timeout and replaced waiting
condition with a more appropriate one.
Test coverage for query_cache_wlock_invalidate behavior for
implicitly locked tables was added to query_cache.test.
mysql-test/suite/sys_vars/t/query_cache_wlock_invalidate_func.test:
Fixed sys_vars.query_cache_wlock_invalidate_func test to not
to wait for timeout of wait_condition.inc script. Reverted
changes to test which introduced timeout and replaced waiting
condition with a more appropriate one.
Test coverage for query_cache_wlock_invalidate behavior for
implicitly locked tables was added to query_cache.test.
mysql-test/t/query_cache.test:
Added test coverage for query_cache_wlock_invalidate
behavior for implicitly locked tables.
mysys/thr_lock.c:
Replaced "Table lock" thread state name, which was used by
threads waiting on thr_lock.c table level lock, with more
elaborate "Waiting for table level lock", to make it
consistent with thread state names which are used while
waiting for metadata locks and table flush.
sql/mdl.cc:
Replaced thread state name "Waiting for table", which was
used by threads waiting for a metadata lock or table flush,
with a set of names which better reflect types of resources
being waited for.
To implement this:
- Adjusted MDL_wait::timed_wait() to take thread state name
as parameter.
- Introduced method of MDL_key class which allows to get
thread state name to be used while waiting for resource
corresponding to the key and changed code to use it.
Added array translating namespaces to thread state names
as part of this change.
sql/mdl.h:
