The flag EXTRA_ACL is used in conjugation with our access checks, yet it is
not clear what impact this flag has.
This is a code clean up which replaces use of EXTRA_ACL with an explicit
function parameter.
The patch also fixes privilege checks for:
- SHOW CREATE TABLE: The new privilege requirement is any privilege on
the table-level.
- CHECKSUM TABLE: Requires SELECT on the table level.
- SHOW CREATE VIEW: Requires SHOW_VIEW and SELECT on the table level
(just as the manual claims)
- SHOW INDEX: Requires any privilege on any column combination.

Implemented the server infrastructure for the fix:
1. Added a function LEX_STRING *thd_query_string(THD) to return
a LEX_STRING structure instead of char *.
This is the function that must be called in innodb instead of
thd_query()
2. Did some encapsulation in THD : aggregated thd_query and
thd_query_length into a LEX_STRING and made accessor and mutator
methods for easy code updating.
3. Updated the server code to use the new methods where applicable.
local storage for query cache).
We need more than one pointer in a thread to
represent the query cache and net->query_cache_query can not be used
any more (due to ABI compatibility issues and to different life
time of NET and THD).

"Patch to fix bug 38551": it was a manual backport (2008-10-15) of
http://lists.mysql.com/commits/56418.
But that was an early, non-final patch from the fixer of this bug (TheK):
after that backport was made by Mikael, TheK decided to do a different fix,
which was finally pushed into 6.0.
Then 5.1's code was changed for some other reasons, so now we have a
conflict between the old never-approved TheK patch backported to Summit and
the latest 5.1. The backport cannot stay, it has to be removed due to
the conflict, and then rewritten if desired.
bzr branch mysql-5.1-performance-version mysql-trunk # Summit
cd mysql-trunk
bzr merge mysql-5.1-innodb_plugin # which is 5.1 + Innodb plugin
bzr rm innobase # remove the builtin
Next step: build, test fixes.
Early patch submitted for discussion.
It is possible for more than one thread to enter the condition
in query_cache_insert(), but the condition predicate is to
signal one thread each time the cache status changes between
the following states: {NO_FLUSH_IN_PROGRESS,FLUSH_IN_PROGRESS,
TABLE_FLUSH_IN_PROGRESS}
Consider three threads THD1, THD2, THD3
THD2: select ... => Got a writer in ::store_query
THD3: select ... => Got a writer in ::store_query
THD1: flush tables => qc status= FLUSH_IN_PROGRESS;
new writers are blocked.
THD2: select ... => Still got a writer and enters cond in
query_cache_insert
THD3: select ... => Still got a writer and enters cond in
query_cache_insert
THD1: flush tables => finished and signal status change.
THD2: select ... => Wakes up and completes the insert.
THD3: select ... => Happily waiting for better times. Why hurry?
This patch is a refactoring of this lock system. It introduces four new methods:
Query_cache::try_lock()
Query_cache::lock()
Query_cache::lock_and_suspend()
Query_cache::unlock()
This change also deprecates wait_while_table_flush_is_in_progress(). All threads are
queued and put on a conditional wait. On each unlock the queue is signalled. This resolve
the issues with left over threads. To assure that no threads are spending unnecessary
time waiting a signal broadcast is issued every time a lock is taken before a full
cache flush.
mysql-test/r/query_cache_debug.result:
* Added test case for bug43758
mysql-test/t/query_cache_debug.test:
* Added test case for bug43758
sql/sql_cache.cc:
* Replaced calls to wait_while_table_flush_is_in_progress() with
calls to try_lock(), lock_and_suspend() and unlock().
* Renamed enumeration Cache_status to Cache_lock_status.
* Renamed enumeration items to UNLOCKED, LOCKED_NO_WAIT and LOCKED.
If the LOCKED_NO_WAIT lock type is used to lock the query cache, other
threads using try_lock() will fail to acquire the lock.
This is useful if the query cache is temporary disabled due to
a full table flush.
sql/sql_cache.h:
* Replaced calls to wait_while_table_flush_is_in_progress() with
calls to try_lock(), lock_and_suspend() and unlock().
* Renamed enumeration Cache_status to Cache_lock_status.
* Renamed enumeration items to UNLOCKED, LOCKED_NO_WAIT and LOCKED.
If the LOCKED_NO_WAIT lock type is used to lock the query cache, other
threads using try_lock() will fail to acquire the lock.
This is useful if the query cache is temporary disabled due to
a full table flush.
The query cache module did not check for the SQL_NO_CACHE keyword before
attempting to query the hash lookup table. This had a small performance impact.
By introducing a check on the query string before obtaining the hash mutex
we can gain some performance if the SQL_NO_CACHE directive is used often.
sql/sql_cache.cc:
* Introduced new helper function, has_no_cache_directive, for checking the
existance of a SQL_NO_CACHE directive before actual parsing of the query.
The problem is that select queries executed concurrently with
a concurrent insert on a MyISAM table could be cached if the
select started after the query cache invalidation but before
the unlock of tables performed by the concurrent insert. This
race could happen because the concurrent insert was failing
to prevent cache of select queries happening at the same time.
The solution is to add a 'uncacheable' status flag to signal
that a concurrent insert is being performed on the table and
that queries executing at the same time shouldn't cache the
results.
mysql-test/r/query_cache_debug.result:
Add test case result for Bug#41098
mysql-test/t/disabled.def:
Re-enable test case.

a preceding invalidate for queries that started before the
concurrent insert.
storage/myisam/ha_myisam.cc:
Check for a active concurrent insert.
storage/myisam/mi_locking.c:
Signal the start of a concurrent insert. Flag is zeroed once
the state is updated back.
storage/myisam/myisamdef.h:
Add flag to signal a active concurrent insert.
There were so many changes into mtr (this is the new mtr coming) that I rather
copied mtr from 6.0-main here (at least this one knows how to run Maria tests).
I also fixed suite/maria tests to be accepted by the new mtr.
mysys/thr_mutex.c:
adding DBUG_PRINT here, so that we can locate where the warning is issued.
- Remove bothersome warning messages. This change focuses on the warnings
that are covered by the ignore file: support-files/compiler_warnings.supp.
- Strings are guaranteed to be max uint in length
The problem is that the query cache was storing partial results
if the statement failed when sending the results to the client.
This could cause clients to hang when trying to read the results
from the cache as they would, for example, wait indefinitely for
a eof packet that wasn't saved.
The solution is to always discard the caching of a query that
failed to send its results to the associated client.
mysql-test/r/query_cache_notembedded.result:
Add test case result for Bug#40264
mysql-test/t/query_cache_notembedded.test:
Add test case for Bug#40264
sql/sql_cache.cc:
Abort if a unreported error was raised.
The problem is that the query cache stores packets containing
the server status of the time when the cached statement was run.
This might lead to a wrong transaction status in the client side
if a statement is cached during a transaction and is later served
outside a transaction context (and vice-versa).
The solution is to take into account the transaction status when
storing in and serving from the query cache.
mysql-test/r/innodb_cache.result:
Update test case result.
mysql-test/r/query_cache.result:
Add test case result for Bug#36326
mysql-test/t/query_cache.test:
Add test case for Bug#36326
sql/mysql_priv.h:
Add new flags.
sql/sql_cache.cc:
Remember the transaction and autocommit status stored in the packet.
tests/mysql_client_test.c:
Add test case for Bug#36326
The query cache module did not check for the SQL_NO_CACHE keyword before
attempting to query the hash lookup table. This had a small performance impact.
By introducing a check on the query string before obtaining the hash mutex
we can gain some performance if the SQL_NO_CACHE directive is used often.
Post-merge bug fix: lock_type is a enumeration type and not a bit mask.
sql/sql_cache.cc:
Check for lock type explicitly. Also err on the safe side and
invalidate the query cache for any write lock.
This patch also fixes bugs 36963 and 35600.
- In many places a view was confused with an anonymous derived
table, i.e. access checking was skipped. Fixed by introducing a
predicate to tell the difference between named and anonymous
derived tables.
- When inserting fields for "SELECT * ", there was no
distinction between base tables and views, where one should be
made. View privileges are checked elsewhere.

Bug no 35600:
In mysql_table_grant:
Replaced conditional with the new accessor method.
In check_grant:
- Changed the requirement table->derived != null to
checking all anonymous derived tables.
- Use of the accessor methods for getting object and database
names.
Bug#36086: In check_grant_all_columns:
- Updated comment. This function is now called for views
as well.
- The error message should not disclose any column names
unless the user has privilege to see all column names.
- Changed names of Field_iterator_table_ref methods.
sql/sql_base.cc:
Bug no 36963: In insert_fields()
- Commented.
- We should call check_grant_all_columns() for views in
this case.
- Changed names of Field_iterator_table_ref methods.
- We should not disclose column names in the error message
when the user has no approprate privilege.
sql/sql_cache.cc:
Bug#36086: Replaced test with new predicate method.
sql/sql_derived.cc:
Bug#36086: commenting only. Updated and doxygenated
comment for mysql_derived_prepare().
sql/sql_parse.cc:
Bug no 35600:
- In check_single_table_access:
Due to the bug, check_grant would raise an error for a
SHOW CREATE TABLE command for a TEMPTABLE view. It should in
fact not be be invoked in this case. This table privilege
is checked already.
There is a test case for this in information_schema_db.test.
- In check_access: replaced table->derived
sql/table.cc:
Bug#36086:
- In TABLE_LIST::set_underlying_merge():
Commenting only. Doxygenated, corrected spelling,
added.
- Renamed table_name() and db_name() methods of
Field_iterator_table_ref in order to be consistent
with new methods in TABLE_LIST.
sql/table.h:
Bug#36086:
- Commented GRANT_INFO.
- Added a predicate is_anonymous_derived_table() to
TABLE_LIST.
- Added get_table_name() and get_db_name() to
TABLE_LIST in order to hide the disparate
representation of these properties.
This bugs clarifies a warning message issued when the query cache data
size becomes smaller than the minium allowed size.
mysql-test/r/query_cache.result:
New warning message when a too small value has been set for query cache
size.
sql/set_var.cc:
To avoid poluting the QC API the warning messages are moved into the
QC module.
sql/share/errmsg.txt:
Changed error message so that minimal cache size always is hinted.
sql/sql_cache.cc:
Modified the warning message so that the minimal cache size always is
hinted.
Added interface method Query_cache::get_minimal_size_limit().
sql/sql_cache.h:
Modified the warning message so that the minimal cache size always is
hinted.
Added interface method Query_cache::get_minimal_size_limit().
if cached query uses many tables
The problem was that query cache would not properly cache
queries which used 256 or more tables but yet would leave
behind query cache blocks pointing to freed (destroyed)
data. Later when invalidating (due to a truncate) query cache
would attempt to grab a lock which resided in the freed data,
leading to hangs or undefined behavior.
This was happening due to a improper return value from the
function responsible for registering the tables used in the
query (so the cache can be invalidated later if one of the
tables is modified). The function expected a return value of
type boolean (char, 8 bits) indicating success (1) or failure
(0) but the number of tables registered (unsigned int, 32 bits)
was being returned instead. This caused the function to return
failure for cases where it had actually succeed because when
a type (unsigned int) is converted to a narrower type (char),
the excess bits on the left are discarded. Thus if the 8
rightmost bits are zero, the return value will be 0 (failure).
The solution is to simply return true (1) only if the number of
registered table is greater than zero and false (0) otherwise.
mysql-test/r/query_cache_merge.result:
Add test case result for Bug#33362
mysql-test/t/query_cache_merge.test:
Add test case for Bug#33362
sql/sql_cache.cc:
Return 1 or 0 depending on the number of registered tables.
