A buffer large enough to hold the query _plus_ some additional
data is allocated before parsing is started. The additional data
is used by the query cache, and consists of the name of the current
database and a set of flags.
When a packet containing multiple SQL statements is sent to the
server and one of the statements changes the current database
(a "USE <db>" statement), and the name of the new current database
is longer than of the previous, there is not enough space in the
buffer for the new name, and we write out over the buffer boundary.
The fix adds an extra field to store the number of bytes
allocated to the database name in the buffer. If the current
database name changes, and the new name is longer than the
previous one, we refuse to cache the query.
- If USER is given, all threads for that user is signaled
- If SOFT is used then the KILL will not be sent to the handler. This can be used to not interrupt critical things in the handler like 'REPAIR'.
Internally added more kill signals. This gives us more information of why a query/connection was killed.
- KILL_SERVER is used when server is going down. In this case the users gets ER_SHUTDOWN as the reason connection was killed.
- Changed signals to number in correct order, which makes it easier to test how the signal should affect the code.
- New error message ER_CONNECTION_KILLED if connection was killed by 'KILL CONNECTION'. Before we got error ER_SHUTDOWN.

Resolved all conflicts, bad merges and fixed a few minor bugs in the code.
Commented out the queries from multi_update, view, subselect_sj, func_str,
derived_view, view_grant that failed either with crashes in ps-protocol or
with wrong results.
The failures are clear indications of some bugs in the code and these bugs
are to be fixed.
Only wait for a single debug signal at a time as the signal state
is global. Also, do not activate the query cache debug sync points
if the thread has no associated THD session.
mysql-test/t/query_cache_debug.test:
Only wait for a single debug signal at a time as the signal state
is global.
sql/sql_cache.cc:
Do not execute the debug sync point if the thread has no associated
THD session. This scenario happens for federated threads.
The problem was that threads waiting on the query cache lock
are not easily seen due to the lack of a state indicating that
the thread is waiting on the said lock. This made it difficult
for users to quickly spot (for example, via SHOW PROCESSLIST)
a query cache contention problem.
The solution is to update the thread state when the query cache
lock needs to be acquired. Whenever the lock is to be acquired,
the thread state is updated to "Waiting for query cache lock"
and is reset once the lock is granted or the wait is interrupted.
The intention is to make query cache related hangs more evident.
To further investigate query cache related locking problems, one
may use PERFORMANCE_SCHEMA to track the overhead associated with
the locking bits and determine which particular lock is being a
contention point.
sql/sql_cache.cc:
Set and reset the thread state whenever a attempt to lock the
query cache is made.
Use DEBUG_SYNC instead of the now unnecessary wait_for_kill hack.
thd->in_sub_stmt
In a precursor patch for Bug#52044
(revid:bzr/kostja@stripped), a
number of reorganizations of code was made. In addition some
assertions were added to ensure the correct transactional state.
The reorganization had a small glitch so statements that was
active in the query cache was not followed by a
statement commit/rollback (this code was removed). A section
in the trans_commit_stmt/trans_rollback_stmt code is to
clear the thd->transaction.stmt list of affected storage
engines. When a new statement is initiated, an assert
introduced by the 523044 patch checks if this list is cleared.
When the query cache is accessed, this list may be populated,
and since it's not committed it will not be cleared.
This fix adds explicit statement commit or rollback for
statements that is contained in the query cache.

compression protocol.
The loss of connection was caused by a malformed packet
sent by the server in case when query cache was in use.
When storing data in the query cache, the query cache
memory allocation algorithm had a tendency to reduce
the amount of memory block necessary to store a result
set, up to finally storing the entire result set in a single
block. With a significant result set, this memory block
could turn out to be quite large - 30, 40 MB and on.
When such a result set was sent to the client, the entire
memory block was compressed and written to network as a
single network packet. However, the length of the
network packet is limited by 0xFFFFFF (16MB), since
the packet format only allows 3 bytes for packet length.
As a result, a malformed, overly large packet
with truncated length would be sent to the client
and break the client/server protocol.
The solution is, when sending result sets from the query
cache, to ensure that the data is chopped into
network packets of size <= 16MB, so that there
is no corruption of packet length. This solution,
however, has a shortcoming: since the result set
is still stored in the query cache as a single block,
at the time of sending, we've lost boundaries of individual
logical packets (one logical packet = one row of the result
set) and thus can end up sending a truncated logical
packet in a compressed network packet.
As a result, on the client we may require more memory than
max_allowed_packet to keep, both, the truncated
last logical packet, and the compressed next packet.
This never (or in practice never) happens without compression,
since without compression it's very unlikely that
a) a truncated logical packet would remain on the client
when it's time to read the next packet
b) a subsequent logical packet that is being read would be
so large that size-of-new-packet + size-of-old-packet-tail >
max_allowed_packet.
To remedy this issue, we send data in 1MB sized packets,
that's below the current client default of 16MB for
max_allowed_packet, but large enough to ensure there is no
unnecessary overhead from too many syscalls per result set.
sql/net_serv.cc:

Essentially, the problem is that safemalloc is excruciatingly
slow as it checks all allocated blocks for overrun at each
memory management primitive, yielding a almost exponential
slowdown for the memory management functions (malloc, realloc,
free). The overrun check basically consists of verifying some
bytes of a block for certain magic keys, which catches some
simple forms of overrun. Another minor problem is violation
of aliasing rules and that its own internal list of blocks
is prone to corruption.
Another issue with safemalloc is rather the maintenance cost
as the tool has a significant impact on the server code.
Given the magnitude of memory debuggers available nowadays,
especially those that are provided with the platform malloc
implementation, maintenance of a in-house and largely obsolete
memory debugger becomes a burden that is not worth the effort
due to its slowness and lack of support for detecting more
common forms of heap corruption.
Since there are third-party tools that can provide the same
functionality at a lower or comparable performance cost, the
solution is to simply remove safemalloc. Third-party tools
can provide the same functionality at a lower or comparable
performance cost.
The removal of safemalloc also allows a simplification of the
malloc wrappers, removing quite a bit of kludge: redefinition
of my_malloc, my_free and the removal of the unused second
argument of my_free. Since free() always check whether the
supplied pointer is null, redudant checks are also removed.
Also, this patch adds unit testing for my_malloc and moves
my_realloc implementation into the same file as the other
memory allocation primitives.
client/mysqldump.c:
Pass my_free directly as its signature is compatible with the
callback type -- which wasn't the case for free_table_ent.
Adding my_global.h first in all files using
NO_EMBEDDED_ACCESS_CHECKS.
Correcting a merge problem resulting from a changed definition
of check_some_access compared to the original patches.
This patch:
- Moves all definitions from the mysql_priv.h file into
header files for the component where the variable is
defined
- Creates header files if the component lacks one
- Eliminates all include directives from mysql_priv.h
- Eliminates all circular include cycles
- Rename time.cc to sql_time.cc
- Rename mysql_priv.h to sql_priv.h

* Introduced a timeout value for the qc lock when entering send_result_to_client()
and store_query() methods.
sql/sql_cache.h:
* New signature for Query_cache::try_lock()
- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs

- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.
This is a re-commit of Monty's merge to eliminate an extra commit from
MySQL-5.1.42 that was accidentally included in the merge.
This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In
case there are any extra changes done before final MySQL 5.1.41
release, these will need to be merged later before MariaDB 5.1.41
release.
When the query cache is disabled, the server shouldn't attempt to take the
query cache mutex.
By using the command line option --query_cache_type=0, the user can disable

sql/set_var.cc:
* Added before-trigger to verify that query_cache_type wasn't turned off or on during
runtime.
sql/set_var.h:
* Changed order on how the enumeration is processed. By first projecting the
character representation of the variable to a temporary integer we can have
one function instead of two to check if the value is valid.
sql/share/errmsg-utf8.txt:
* Added error message for query cache disabled state
sql/sql_cache.cc:
* If the query cache is disabled at start up, shorten the execution path and avoid
grabbing the query cache mutex each time the invalidate interface methods are called.
sql/sql_cache.h:
* Added new methods to set the query cache into a disabled state.

some other minor revisions.
This patch implements:
WL#4264 "Backup: Stabilize Service Interface" -- all the
server prerequisites except si_objects.{h,cc} themselves (they can
be just copied over, when needed).
WL#4435: Support OUT-parameters in prepared statements.
(and all issues in the initial patches for these two
tasks, that were discovered in pushbuild and during testing).
Bug#39519: mysql_stmt_close() should flush all data
associated with the statement.
After execution of a prepared statement, send OUT parameters of the invoked
stored procedure, if any, to the client.
When using the binary protocol, send the parameters in an additional result
set over the wire. When using the text protocol, assign out parameters to
the user variables from the CALL(@var1, @var2, ...) specification.
The following refactoring has been made:
- Protocol::send_fields() was renamed to Protocol::send_result_set_metadata();
- A new Protocol::send_result_set_row() was introduced to incapsulate
common functionality for sending row data.
- Signature of Protocol::prepare_for_send() was changed: this operation
does not need a list of items, the number of items is fully sufficient.
The following backward incompatible changes have been made:
- CLIENT_MULTI_RESULTS is now enabled by default in the client;
- CLIENT_PS_MULTI_RESUTLS is now enabled by default in the client.
include/mysql.h:
Add a new flag to MYSQL_METHODS::flush_use_result
function pointer. This flag determines if all results
should be flushed or only the first one:
- if flush_all_results is TRUE, then cli_flush_use_result()
will read/flush all pending results. I.e. it will read
all packets while server status attribute indicates that
there are more results. This is a new semantic, required
to fix the bug.
- if flush_all_results is FALSE, the old sematic
is preserved -- i.e. cli_flush_use_result() reads data
until first EOF-packet.
include/mysql.h.pp:
Update the ABI with new calls (compatible changes).
include/mysql_com.h:
Add CLIENT_PS_OUT_PARAMS -- a client capability indicating that the client supportsю
libmysql/libmysql.c:
Add mysql_stmt_next_result() -- analogue of mysql_next_result() for binary protocol.
Fix a minor bug in alloc_fields() -- not all members were copied over,
and some only shallow-copied (catalog).
Flush all results in mysql_stmt_close() (Bug#39519).
libmysqld/lib_sql.cc:
Rename send_fields() -> send_result_set_metadata().
Refactoring: change prepare_for_send() so that it accepts only
what it really needs -- a number of elements in the list.
mysql-test/r/ps.result:
Update results: WL#4435.
mysql-test/t/ps.test:
WL#4435: A test case for an SQL-part of the problem.
sql-common/client.c:
Bug#39519.
Implement new functionality in cli_flush_use_result():
if flush_all_delete is TRUE, then it should read/flush
all pending results.
sql/Makefile.am:
Add a new header sql_prepare.h to the list
of build headers.
sql/events.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/handler.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/mysql_priv.h:
Move sql_prepare.cc-specific declarations to a new
header - sql_prepare.h.
sql/procedure.h:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/protocol.cc:
Move the logic responsible for sending of one result
set row to the Protocol class. Define a template
for end-of-statement action.
Refactoring: change prepare_for_send() so that it accepts
only what it really needs -- a number of elements in the list.
Rename send_fields() to send_result_set_metadata().
sql/protocol.h:
Update with new declarations (WL#4435).
Rename send_fields() -> send_result_set_metadata().
prepare_for_send() only needs the number of columns to send,
and doesn't use the item list - update signature to require
only what's needed.
Add a new protocol type -- Protocol_local.
sql/repl_failsafe.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/slave.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_acl.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_base.cc:
Include sql_prepare.h (for Reprepare_observer).
sql/sql_cache.cc:
Extend the query cache flags block to be able
to store a numeric id for the result format,
not just a flag binary/non-binary.
sql/sql_class.cc:
Update to use the rename of Protocol::send_fields()
to Protocol::send_result_set_metadata().
Use Protocol::send_one_result_set_row().
sql/sql_class.h:
Move the declaration of Reprepare_observer to the
new header - sql_prepare.h.
Update to the new signature of class Protocol::send_fields().
sql/sql_connect.cc:
Use a protocol template method instead of
raw NET layer API at the end of a statement.
sql/sql_cursor.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_error.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_handler.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
Use new method Protocol::send_one_result_set_row().
sql/sql_help.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_lex.cc:
Initialize multi_statements variable.
Add a handy constant for empty lex
string.
sql/sql_lex.h:
Add a separate member for a standalone
parsing option - multi-statements support.
sql/sql_list.cc:
sql_list.h is a standalone header now,
no need to include mysql_priv.h.
sql/sql_list.h:
Make sql_list.h a stand-alone header.
sql/sql_parse.cc:
Include sql_prepare.h for prepared
statements- related declarations.
Use a new Protocol template method to end
each statement (send OK, EOF or ERROR to
the client).
sql/sql_prepare.cc:
Implement Execute Direct API (WL#4264),
currently unused. It will be used by the service
interface (Backup).
Use a new header - sql_prepare.h.
Add support for OUT parameters in the
binary and text protocol (prepared statements
only).
sql/sql_prepare.h:
Add a new header to contain (for now)
all prepared statement- external
related declarations.
sql/sql_profile.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_repl.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_select.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_show.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_string.h:
Add a way to convert a String to LEX_STRING.
sql/sql_table.cc:
Rename: Protocol::send_fields() ->
Protocol::send_result_set_metadata().
sql/sql_update.cc:
Remove an extraneous my_error(). The error
is already reported in update_non_unique_table_error().
sql/sql_yacc.yy:
Support for multi-statements is an independent
property of parsing, not derived from
the protocol type.
tests/mysql_client_test.c:
Add tests for WL#4435 (binary protocol).
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.

Use struct Query_cache_block (not class) for forward declaration,
realing the code to match 6.0 alignment.
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.

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.

sql/item.cc:
Bug#36086: Replaced conditional with new methods.
sql/sql_acl.cc:
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:

The initial value of free memory blocks in 0. When the query cache is enabled
a new memory block gets allocated and is assigned number 1. The free memory
block is later split each time query cache memory is allocated for new blocks.
This means that the free memory block counter won't be reduced to zero when
the number of allocated blocks are zero, but rather one. To avoid confusion
this patch changes this behavior so that the free memory block counter is
reset to zero when the query cache is disabled.
Note that when the query cache is enabled and resized the free memory block
counter was still calculated correctly.

pre-locking.
The crash was caused by an implicit assumption in check_table_access() that
table_list parameter is always a part of lex->query_tables.
When iterating over the passed list of tables, check_table_access() used
to stop only when lex->query_tables_last_not_own was reached.
In case of pre-locking, lex->query_tables_last_own is not NULL and points
to some element of lex->query_tables. When the parameter
of check_table_access() was not part of lex->query_tables, loop invariant
could never be violated and a crash would happen when the current table
pointer would point beyond the end of the provided list.
The fix is to change the signature of check_table_access() to also accept
a numeric limit of loop iterations, similarly to check_grant(), and
supply this limit in all places when we want to check access of tables
that are outside lex->query_tables, or just want to check access to one table.

whereas check_table_access() used to assume that the supplied list is a part
of thd->lex.

Reseting the query cache by issuing a SET GLOBAL query_cache_size=0 caused the server
to crash if a the server concurrently was saving a new result set to the query cache. The
reason for this was that the invalidation wasn't waiting on the result writers to
release the block level locks on the query cache.
mysql-test/r/query_cache.result:
Added test for verifying that 'SET query_cache_size= 0' while inserting new
statements into the query cache won't cause the server to crash.
mysql-test/t/query_cache.test:
Added test for verifying that 'SET query_cache_size= 0' while inserting new

writers and readers from crashing when the query cache is removed.

cause ROLLBACK of statement", part 1. Review fixes.
Do not send OK/EOF packets to the client until we reached the end of
the current statement.
This is a consolidation, to keep the functionality that is shared by all
SQL statements in one place in the server.
Currently this functionality includes:
- close_thread_tables()
- log_slow_statement().
After this patch and the subsequent patch for Bug#12713, it shall also include:
- ha_autocommit_or_rollback()
- net_end_statement()
- query_cache_end_of_result().
In future it may also include:
- mysql_reset_thd_for_next_command().
include/mysql_com.h:
Rename now unused members of NET: no_send_ok, no_send_error, report_error.
These were server-specific variables related to the client/server
protocol. They have been made obsolete by this patch.
Previously the same members of NET were used to store the error message
both on the client and on the server.
The error message was stored in net.last_error (client: mysql->net.last_error,
server: thd->net.last_error).
The error code was stored in net.last_errno (client: mysql->net.last_errno,
server: thd->net.last_errno).
The server error code and message are now stored elsewhere
(in the Diagnostics_area), thus NET members are no longer used by the
server.
Rename last_error to client_last_error, last_errno to client_last_errno
to avoid potential bugs introduced by merges.
include/mysql_h.ic:
Update the ABI file to reflect a rename.
Renames do not break the binary compatibility.
libmysql/libmysql.c:
Rename last_error to client_last_error, last_errno to client_last_errno.
This is necessary to ensure no unnoticed bugs introduced by merged
changesets.
Remove net.report_error, net.no_send_ok, net.no_send_error.
libmysql/manager.c:
Rename net.last_errno to net.client_last_errno.
libmysqld/lib_sql.cc:
Rename net.last_errno to net.client_last_errno.
Update the embedded implementation of the client-server protocol to
reflect the refactoring of protocol.cc.
libmysqld/libmysqld.c:
Rename net.last_errno to net.client_last_errno.
mysql-test/r/events.result:
Update to reflect the change in mysql_rm_db(). Now we drop stored
routines and events for a given database name only if there
is a directory for this database name. ha_drop_database() and
query_cache_invalidate() are called likewise.
Previously we would attempt to drop routines/events even if database
directory was not found (it worked, since routines and events are stored
in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc
does not exist".
The change was done because the previous code used to call send_ok()
twice, which led to an assertion failure when asserts against it were
added by this patch.
mysql-test/r/grant.result:
Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error
if mysql.procs_priv is missing.
This fixes the assert that send_ok() must not called after send_error()
(the original patch for Bug 16470 was prone to this).
mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result:
Produce a more detailed error message.
mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result:
Produce a more detailed error message.
mysql-test/t/grant.test:
Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv
is missing.
server-tools/instance-manager/mysql_connection.cc:
Rename net.last_errno to net.client_last_errno.
sql/ha_ndbcluster_binlog.cc:
Add asserts.
Use getters to access statement status information.
Add a comment why run_query() is broken. Reset the diagnostics area
in the end of run_query() to fulfill the invariant that the diagnostics_area
is never assigned twice per statement (see the comment in the code
when this can happen). We still do not clear thd->is_fatal_error and
thd->is_slave_error, which may lead to bugs, I consider the whole affair
as something to be dealt with separately.
sql/ha_partition.cc:
fatal_error() doesn't set an error by itself. Perhaps we should
remove this method altogether and instead add a flag to my_error
to set thd->is_fatal_error property.
Meanwhile, this change is a part of inspection made to the entire source
code with the goal to ensure that fatal_error()
is always accompanied by my_error().
sql/item_func.cc:
There is no net.last_error anymore. Remove the obsolete assignment.
sql/log_event.cc:
Use getters to access statement error status information.
sql/log_event_old.cc:
Use getters to access statement error status information.
sql/mysqld.cc:
Previously, if a continue handler for an error was found, my_message_sql()
would not set an error in THD. Since the current statement
must be aborted in any case, find_handler() had a hack to assign
thd->net.report_error to 1.
Remove this hack. Set an error in my_message_sql() even if the continue
handler is found. The error will be cleared anyway when the handler
is executed. This is one action among many in this patch to ensure the
invariant that whenever thd->is_error() is TRUE, we have a message in
thd->main_da.message().
sql/net_serv.cc:
Use a full-blown my_error() in net_serv.cc to report an error,
instead of just setting net->last_errno. This ensures the invariant that
whenever thd->is_error() returns TRUE, we have a message in
thd->main_da.message().
Remove initialization of removed NET members.
sql/opt_range.cc:
Use my_error() instead of just raising thd->net.report_error.
This ensures the invariant that whenever thd->is_error() returns TRUE,
there is a message in thd->main_da.message().
sql/opt_sum.cc:
Move invocation of fatal_error() right next to the place where
we set the error message. That makes it easier to track that whenever
fatal_error() is called, there is a message in THD.
sql/protocol.cc:
Rename send_ok() and send_eof() to net_send_ok() and net_send_eof()
respectively. These functions write directly to the network and are not
for use anywhere outside the client/server protocol code.
Remove the code that was responsible for cases when either there is
no error code, or no error message, or both.
Instead the calling code ensures that they are always present. Asserts
are added to enforce the invariant.
Instead of a direct access to thd->server_status and thd->total_warn_count
use function parameters, since these from now on don't always come directly
from THD.
Introduce net_end_statement(), the single-entry-point replacement API for
send_ok(), send_eof() and net_send_error().
Implement Protocol::end_partial_result_set to use in select_send::abort()
when there is a continue handler.
sql/protocol.h:
Update declarations.
sql/repl_failsafe.cc:
Use getters to access statement status information in THD.
Rename net.last_error to net.client_last_error.
sql/rpl_record.cc:
Set an error message in prepare_record() if there is no default
value for the field -- later we do print this message to the client.
sql/rpl_rli.cc:
Use getters to access statement status information in THD.
sql/slave.cc:
In create_table_from_dump() (a common function that is used in
LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks
with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded.
Update has_temporary_error() to work correctly when no error is set.
This is the case when Incident_log_event is executed: it always returns
an error but does not set an error message.
Use getters to access error status information.
sql/sp_head.cc:
Instead of hacks with no_send_error, work through the diagnostics area
interface to suppress sending of OK/ERROR packets to the client.
Move query_cache_end_of_result before log_slow_statement(), similarly
to how it's done in dispatch_command().
sql/sp_rcontext.cc:
Remove hacks with assignment of thd->net.report_error, they are not
necessary any more (see the changes in mysqld.cc).
sql/sql_acl.cc:
Use getters to access error status information in THD.
sql/sql_base.cc:
Access thd->main_da.sql_errno() only if there is an error. This fixes
a bug when auto-discovery, that was effectively disabled under pre-locking.
sql/sql_binlog.cc:
Remove hacks with no_send_ok/no_send_error, they are not necessary
anymore: the caller is responsible for network communication.
sql/sql_cache.cc:
Disable sending of OK/ERROR/EOF packet in the end of dispatch_command
if the response has been served from the query cache. This raises the
question whether we should store EOF packet in the query cache at all,
or generate it anew for each statement (we should generate it anew), but
this is to be addressed separately.
sql/sql_class.cc:
Implement class Diagnostics_area. Please see comments in sql_class.h
for details.
Fix a subtle coding mistake in select_send::send_data: when on slave,
an error in Item::send() was ignored.
The problem became visible due to asserts that the diagnostics area is
never double assigned.
Remove initialization of removed NET members.
In select_send::abort() do not call select_send::send_eof(). This is
not inheritance-safe. Even if a stored procedure continue handler is
found, the current statement is aborted, not succeeded.
Instead introduce a Protocol API to send the required response,
Protocol::end_partial_result_set().
This simplifies implementation of select_send::send_eof(). No need
to add more asserts that there is no error, there is an assert inside
Diagnostics_area::set_ok_status() already.
Leave no trace of no_send_* in the code.
sql/sql_class.h:
Declare class Diagnostics_area.
Remove the hack with no_send_ok from
Substatement_state.
Provide inline implementations of send_ok/send_eof.
Add commetns.
sql/sql_connect.cc:
Remove hacks with no_send_error.
Since now an error in THD is always set if net->error, it's not necessary
to check both net->error and thd->is_error() in the do_command loop.
Use thd->main_da.message() instead of net->last_errno.
Remove the hack with is_slave_error in sys_init_connect. Since now we do not
reset the diagnostics area in net_send_error (it's reset at the beginning
of the next statement), we can access it safely even after
execute_init_command.
sql/sql_db.cc:
Update the code to satisfy the invariant that the diagnostics area is never
assigned twice.
Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if
mysql.proc does not exist".
sql/sql_delete.cc:
Change multi-delete to abort in abort(), as per select_send protocol.
Fixes the merge error with the test for Bug 29136
sql/sql_derived.cc:
Use getters to access error information.
sql/sql_insert.cc:
Use getters to access error information.
sql-common/client.c:
Rename last_error to client_last_error, last_errno to client_last_errno.
sql/sql_parse.cc:
Remove hacks with no_send_error. Deploy net_end_statement().
The story of COM_SHUTDOWN is interesting. Long story short, the server
would become on its death's door, and only no_send_ok/no_send_error assigned
by send_ok()/net_send_error() would hide its babbling from the client.
First of all, COM_QUIT does not require a response. So, the comment saying
"Let's send a response to possible COM_QUIT" is not only groundless
(even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after
COM_SHUTDOWN), it's plainly incorrect.
Secondly, besides this additional 'OK' packet to respond to a hypothetical
COM_QUIT, there was the following code in dispatch_command():
if (thd->killed)
thd->send_kill_message();
if (thd->is_error()
net_send_error(thd);
This worked out really funny for the thread through which COM_SHUTDOWN
was delivered: we would get COM_SHUTDOWN, say okay, say okay again,
kill everybody, get the kill signal ourselves, and then attempt to say
"Server shutdown in progress" to the client that is very likely long gone.
This all became visible when asserts were added that the Diagnostics_area
is not assigned twice.
Move query_cache_end_of_result() to the end of dispatch_command(), since
net_send_eof() has been moved there. This is safe, query_cache_end_of_result()
is a no-op if there is no started query in the cache.
Consistently use select_send interface to call abort() or send_eof()
depending on the operation result.
Remove thd->fatal_error() from reset_master(), it was a no-op.
in hacks with no_send_error woudl save us
from complete breakage of the client/server protocol.
Consistently use select_send::abort() whenever there is an error,
and select_send::send_eof() in case of success.
The issue became visible due to added asserts.
sql/sql_partition.cc:
Always set an error in THD whenever there is a call to fatal_error().
sql/sql_prepare.cc:
Deploy class Diagnostics_area.
Remove the unnecessary juggling with the protocol in
Select_fetch_protocol_binary::send_eof(). EOF packet format is
protocol-independent.
sql/sql_select.cc:
Call fatal_error() directly in opt_sum_query.
Call my_error() whenever we call thd->fatal_error().
sql/sql_servers.cc:
Use getters to access error information in THD.
sql/sql_show.cc:
Use getters to access error information in THD.
Add comments.
Call my_error() whenever we call fatal_error().
sql/sql_table.cc:
Replace hacks with no_send_ok with the interface of the diagnostics area.
Clear the error if ENOENT error in ha_delete_table().
sql/sql_update.cc:
Introduce multi_update::abort(), which is the proper way to abort a
multi-update. This fixes the merge conflict between this patch and
the patch for Bug 29136.
sql/table.cc:
Use a getter to access error information in THD.
sql/tztime.cc:
Use a getter to access error information in THD.

The embedded version of the server doesn't use column level grants, and
the compile directive NO_EMBEDDED_ACCESS_CHECKS should be checked instead of
the redundant HAVE_QUERY_CACHE (which is always the case) to determine if
column level grants should be compiled or not.
mysql-test/r/query_cache.result:
Updated result file
mysql-test/r/query_cache_notembedded.result:
Updated result file
mysql-test/t/query_cache.test:
Moved test with GRANT to query_cache_notembedded test.
mysql-test/t/query_cache_notembedded.test:
Moved test with GRANT to query_cache_notembedded test.
sql/sql_cache.cc:
Changed the conditional compilation directive to only compile column level grant
checks if NO_EMBEDDED_ACCESS_CHECKS isn't defined.
"pthread_mutex_trylock" isn't implemented correctly for the Windows platform.
This temporary patch reverts the patch for bug#21074 for Windows until
pthread_mutex_trylock is properly implemented.
sql/sql_cache.cc:
Added code branch for the Windows platform to avoid a faulty pthread_mutex_trylock
implementation.

Invaldating a subset of a sufficiently large query cache can take a long time.
During this time the server is efficiently frozen and no other operation can
be executed. This patch addresses this problem by setting a time limit on
how long time a dictionary access request can take before giving up on the
attempt. This patch does not work for query cache invalidations issued by
DROP, ALTER or RENAME TABLE operations.
sql/sql_cache.cc:
Changed mutex locking to a timed spinn lock. If access to query cache dictionary
takes "a long time" (currently more than 0.1 seconds) the system fall backs on
ordinary statement execution.
