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:
Add declarations for new members and methods.
Make is_cacheable() a static method.
Add query_cache_init_query() function.
sql/sql_class.cc:
Use query_cache_init_query() for initialization of
NET::query_cache_query.

when high concurrency": remove HASH::current_record and make it

race condition under high concurrent load.
The bug was in a race condition in table_hash_search,
when column_priv_hash.current_record was overwritten simultaneously
by multiple threads, causing the search for a suitable grant record
to fail.
No test case as the bug is repeatable only under concurrent load.

response. (Bug #6511)
sql/mysql_priv.h:
Add bit for storing client protocol info
sql/sql_cache.cc:
Record whether 4.1 or old protocol is used for query
Split TABLE to TABLE and TABLE_SHARE (TABLE_SHARE is still allocated as part of table, will be fixed soon)
Created Field::make_field() and made Field_num::make_field() to call this
Added 'TABLE_SHARE->db' that points to database name; Changed all usage of table_cache_key as database name to use this instead
Changed field->table_name to point to pointer to alias. This allows us to change alias for a table by just updating one pointer.
Renamed TABLE_SHARE->real_name to table_name
Renamed TABLE->table_name to alias
Renamed TABLE_LIST->real_name to table_name
include/myisam.h:
Added const before names
mysql-test/r/group_min_max.result:
Make results repeatable
mysql-test/t/group_min_max.test:
Make results repeatable
sql/field.cc:
Created Field::make_field() and made Field_num::make_field() to call this
Use TABLE_SHARE
Use sql_strmake() instead of sql_memdup() to simplify code

Changed table_name to be pointer to table_name. This allows us to change alias for all fields by just changing one pointer.
