There were two problems: RESET QUERY CACHE took a long time to complete
and other threads were blocked during this time.
The patch does three things:
1 fixes a bug with improper use of test-lock-test_again technique.
AKA Double-Checked Locking is applicable here only in few places.
2 Somewhat improves performance of RESET QUERY CACHE.
Do my_hash_reset() instead of deleting elements one by one. Note
however that the slowdown also happens when inserting into sorted
list of free blocks, should be rewritten using balanced tree.
3 Makes RESET QUERY CACHE non-blocking.
The patch adjusts the locking protocol of the query cache in the
following way: it introduces a flag flush_in_progress, which is
set when Query_cache::flush_cache() is in progress. This call
sets the flag on enter, and then releases the lock. Every other
call is able to acquire the lock, but does nothing if
flush_in_progress is set (as if the query cache is disabled).
The only exception is the concurrent calls to
Query_cache::flush_cache(), that are blocked until the flush is
over. When leaving Query_cache::flush_cache(), the lock is
acquired and the flag is reset, and one thread waiting on
Query_cache::flush_cache() (if any) is notified that it may
proceed.
include/mysql_com.h:
Add comment for NET::query_cache_query.
sql/net_serv.cc:
Use query_cache_init_query() for initialization of
NET::query_cache_query if query cache is used.
Do not access net->query_cache_query without a lock.
sql/sql_cache.cc:
Fix bug with accessing query_cache_size, Query_cache_query::wri and
thd->net.query_cache_query before acquiring the lock---leave
double-check locking only in safe places.
Wherever we check that cache is usable (query_cache_size > 0) we now
also check that flush_in_progress is false, i.e. we are not in the
middle of cache flush.
Add Query_cache::not_in_flush_or_wait() method and use it in
Query_cache::flush_cache(), so that threads doing cache flush will
wait it to finish, while other threads will bypass the cache as if
it is disabled.
Extract Query_cache::free_query_internal() from Query_cache::free_query(),
which does not removes elements from the hash, and use it together with
my_hash_reset() in Query_cache::flush_cache().
sql/sql_cache.h:

when calling a SP from C API"
The bug was caused by lack of checks for misuse in mysql_real_query.
A stored procedure always returns at least one result, which is the
status of execution of the procedure itself.
This result, or so-called OK packet, is similar to a result
returned by INSERT/UPDATE/CREATE operations: it contains the overall
status of execution, the number of affected rows and the number of
warnings. The client test program attached to the bug did not read this
result and ivnoked the next query. In turn, libmysql had no check for
such scenario and mysql_real_query was simply trying to send that query
without reading the pending response, thus messing up the communication
protocol.
The fix is to return an error from mysql_real_query when it's called
prior to retrieval of all pending results.

Return CR_COMMANDS_OUT_OF_SYNC on attempt to execute a statement

sql-common/client.c:
Actual fix for Bug#15752: if the server has pending result sets for
the client, return CR_COMMANDS_OUT_OF_SYNC on attempt to execute
another query. Similarly to the behaviour of mysql_use_result(),
multiple result sets block the connection and must be fetched
before it can be used for another query.
This uncovered an error in the protocol: the server doesn't drop
SERVER_MORE_RESULTS_EXISTS status flag upon an error, so in case of
a multi-query like SELECT 1; SELECT syntax_error; SELECT 2;
the client has no way to know that the server won't ever come to
execution of the third query and won't return any result sets for it.
For now, fix it in cli_safe_read, as a proper fix requires extension
of the client-server protocol.

NDB table".
SQL-layer was not marking fields which were used in triggers as such. As
result these fields were not always properly retrieved/stored by handler
layer. So one might got wrong values or lost changes in triggers for NDB,
Federated and possibly InnoDB tables.
This fix solves the problem by marking fields used in triggers
appropriately.
Also this patch contains the following cleanup of ha_ndbcluster code:
We no longer rely on reading LEX::sql_command value in handler in order
to determine if we can enable optimization which allows us to handle REPLACE
statement in more efficient way by doing replaces directly in write_row()
method without reporting error to SQL-layer.
Instead we rely on SQL-layer informing us whether this optimization
applicable by calling handler::extra() method with
HA_EXTRA_WRITE_CAN_REPLACE flag.
As result we no longer apply this optimzation in cases when it should not
be used (e.g. if we have on delete triggers on table) and use in some
additional cases when it is applicable (e.g. for LOAD DATA REPLACE).
Finally this patch includes fix for bug#20728 "REPLACE does not work
correctly for NDB table with PK and unique index".
This was yet another problem which was caused by improper field mark-up.
During row replacement fields which weren't explicity used in REPLACE
statement were not marked as fields to be saved (updated) so they have
retained values from old row version. The fix is to mark all table
fields as set for REPLACE statement. Note that in 5.1 we already solve
this problem by notifying handler that it should save values from all
fields only in case when real replacement happens.
include/my_base.h:
Added HA_EXTRA_WRITE_CAN_REPLACE, HA_EXTRA_WRITE_CANNOT_REPLACE - new
parameters for ha_extra() method. We use them to inform handler that
write_row() which tries to insert new row into the table and encounters
some already existing row with same primary/unique key can replace old
row with new row instead of reporting error.
mysql-test/r/federated.result:
Additional test for bug#18437 "Wrong values inserted with a before update

Item_trigger_field::setup_field():
Added comment explaining why we don't set Field::query_id in this method.
sql/mysql_priv.h:
mysql_alter_table() function no longer takes handle_duplicates argument.
Added declaration of mark_fields_used_by_triggers_for_insert_stmt() function.
sql/sql_delete.cc:
Mark fields which are used by ON DELETE triggers so handler will retrieve
values for these fields.
sql/sql_insert.cc:
Explicitly inform handler that we are doing REPLACE (using ha_extra() method)
in cases when it can promote insert operation done by write_row() to replace.
Also when we do REPLACE we want to store values for all columns so we should
inform handler about it.
Finally we should mark fields used by ON UPDATE/ON DELETE triggers as such
so handler can properly retrieve/restore values in these fields during
execution of REPLACE and INSERT ... ON DUPLICATE KEY UPDATE statements.
sql/sql_load.cc:
Explicitly inform handler that we are doing LOAD DATA REPLACE (using
ha_extra() method) in cases when it can promote insert operation done by
write_row() to replace.
Also when we do replace we want to save (replace) values for all columns
so we should inform handler about it.
Finally to properly execute LOAD DATA for table with triggers we should
mark fields used by ON INSERT triggers as such so handler can properly
store values for these fields.
sql/sql_parse.cc:
mysql_alter_table() function no longer takes handle_duplicates argument.
sql/sql_table.cc:
Got rid of handle_duplicates argument in mysql_alter_table() and
copy_data_between_tables() functions. These functions were always
called with handle_duplicates == DUP_ERROR and thus contained dead
(and probably incorrect) code.
sql/sql_trigger.cc:
Added Table_triggers_list::mark_fields_used() method which is used to mark
fields read/set by triggers as such so handlers will be able properly
retrieve/store values in these fields.
sql/sql_trigger.h:
Table_triggers_list:
Added mark_fields_used() method which is used to mark fields read/set by
triggers as such so handlers will be able properly retrieve/store values
in these fields. To implement this method added 'trigger_fields' member
which is array of lists linking items for all fields used in triggers
grouped by event and action time.
sql/sql_update.cc:
Mark fields which are used by ON UPDATE triggers so handler will retrieve
and save values for these fields.

Both bugs are caused by attempting to delete an opened

name. On Windows it can be supported only on NT-platforms
(by using FILE_SHARE_DELETE mode and with renaming the
file before deletion). Because deleting not-closed files
is not supported on all platforms (e.g. Win 98|ME) this
is to be considered harmful and should be eliminated by
a "code redesign".

- A segfault occured when the function 'kill_server' called
'my_sigset' with signal number 0. 'my_sigset' is a macro which
uses 'sigaction' to install the signal handler with an invalid
signal number will on most platforms return EINVAL but yields
a segfauilt on IRIX 6.5
- The server crash was detected by mysqld_safe and it was restarted although
a shutdown was requested.
- Semantics of kill_server(0) is not known, leaving it intact
include/my_pthread.h:
Check return value from sigaction with a DBUG_ASSERT
Also DBUG_ASSERT if signal number 0 is passed
sql/mysqld.cc:
Don't call my_sigset if signo is 0
client/mysqlbinlog.cc:
Now my_end() deallocates DBUG by default, but that fails in mysqlbinlog
because of global destructors that use DBUG.
dbug/dbug.c:
Add a facility to deallocate the debug stack, to avoid memory leak warnings
in Valgrind.
include/my_dbug.h:
Add a facility to deallocate the debug stack, to avoid memory leak warnings
in Valgrind.
include/my_sys.h:
Change my_end() to deallocate DBUG memory by default (can be disabled with
MY_DONT_FREE_DBUG option).
libmysql/libmysql.c:
Do not deallocate DBUG during cleanup.
mysys/my_init.c:
Change my_end() to deallocate DBUG memory by default (can be disabled with
MY_DONT_FREE_DBUG option).
sql/mysqld.cc:
Add missing my_thread_end() call, seems to occasionally trigger a memory
leak (not repeatable).
