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

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.

Replaced thread state name "Waiting for table", which was
used by threads waiting for table flush, with a more elaborate

hide_view_error() does not take into account that thread query may be killed.

message:
Bug#39897: lock_multi fails in pushbuild: timeout waiting for processlist
The problem is that relying on the "Table lock" thread state in
its current position to detect that a thread is waiting on a lock
is race prone. The "Table lock" state change happens before the
thread actually tries to grab a lock on a table.
The solution is to move the "Table lock" state so that its set
only when a thread is actually going to wait for a lock. The state
change happens after the thread fails to grab the lock (because it
is owned by other thread) and proceeds to wait on a condition.
This is considered part of work related to WL#4284 "Transactional
DDL locking"
Warning: this patch contains an incompatible change.
When waiting on a lock in thr_lock.c, the server used to display "Locked"
processlist state. After this patch, the state is "Table lock".
The new state was actually intended to be display since year 2002,
when Monty added it. But up until removal of thd->locked boolean
member, this state was ignored by SHOW PROCESSLIST code.
mysql-test/r/lock_multi.result:
A style fix.
mysql-test/r/sp-threads.result:
Changed output of SHOW PROCESSLIST (new wait state).
mysql-test/t/lock_multi.test:
Use a more accurate state description when waiting inside thr_lock.c.
mysql-test/t/lock_sync.test:
Use a more accurate state description when waiting inside thr_lock.c.
mysql-test/t/multi_update.test:
Use a more accurate state description when waiting inside thr_lock.c.
mysql-test/t/query_cache_28249.test:
Use a more accurate state description when waiting inside thr_lock.c.
mysql-test/t/sp_notembedded.test:
Use a more accurate state description when waiting inside thr_lock.c.
mysql-test/t/status.test:
Use a more accurate state description when waiting inside thr_lock.c.
mysys/thr_lock.c:
Update thread state while waiting for a table lock.
sql/lock.cc:
State change was moved inside thr_lock.c.
an assertion in a debug build.
The reason is that the C API doesn't support multiple result sets for prepared
statements and attempting to execute a stored routine which returns multiple result
sets sometimes lead to a network error. The network error sets the diagnostic area
prematurely which later leads to the assert when an attempt is made to set a second
server state.
This patch fixes the issue by changing the scope of the error code returned by
sp_instr_stmt::execute() to include any error which happened during the execution.
To assure that Diagnostic_area::is_sent really mean that the message was sent all
network related functions are checked for return status.

The crash happens because of uninitialized
lex->ssl_cipher, lex->x509_subject, lex->x509_issuer variables.
The fix is to add initialization of these variables for
stored procedures&functions.

+ Fix for Bug#43114 wait_until_count_sessions too restrictive, random PB failures
+ Removal of a lot of other weaknesses found
+ modifications according to review
The problem is that since MyISAM's concurrent_insert is on by
default some concurrent SELECT statements might not see changes
made by INSERT statements in other connections, even if the
INSERT statement has returned.
The solution is to disable concurrent_insert so that INSERT
statements returns after the data is actually visible to other
statements.
mysql-test/r/flush_read_lock_kill.result:
Restore old value of @@global.concurrent_insert
mysql-test/r/kill.result:
Restore old value of @@global.concurrent_insert
mysql-test/r/sp_notembedded.result:
Update test case result

Restore old value of @@global.concurrent_insert so it
doesn't affect other tests.
mysql-test/t/kill.test:
Restore old value of @@global.concurrent_insert so it
doesn't affect other tests.
mysql-test/t/sp_notembedded.test:
Disable and restore concurrent_insert value at the end of the
test case. The test case for Bug 29936 requires that the inserted
rows need to be visible before a SELECT statement is queued in
another connection.
Remove sleep at the start of the test, it's not necessary to log
the result of the processlist command, showing the warnings has
the same end result.
the first query is not running while we are doing wait queries on
a second connection.
