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
TRUNCATE TABLE fails to replicate when stmt-based binlogging is not supported.
There were two separate problems with the code, both of which are fixed with
this patch:
1. An error was printed by InnoDB for TRUNCATE TABLE in statement mode when
the in isolation levels READ COMMITTED and READ UNCOMMITTED since InnoDB
does permit statement-based replication for DML statements. However,
the TRUNCATE TABLE is not transactional, but is a DDL, and should therefore
be allowed to be replicated as a statement.
2. The statement was not logged in mixed mode because of the error above, but
the error was not reported to the client.
This patch fixes the problem by treating TRUNCATE TABLE a DDL, that is, it is
always logged as a statement and not reporting an error from InnoDB for TRUNCATE
TABLE.

sql/sql_delete.cc:
Re-organizing code to ensure that TRUNCATE TABLE is logged in statement
format and that row format is not used unless there are rows to log (which
there are not when delete_all_rows() is called, so this has to be logged
as a statement).

locking type of temp table
The problem is that INSERT INTO .. SELECT FROM .. and CREATE
TABLE .. SELECT FROM a temporary table could inadvertently
overwrite the locking type of the temporary table. The lock
type of temporary tables should be a write lock by default.
The solution is to reset the lock type of temporary tables
back to its default value after they are used in a statement.

sql/sql_base.cc:
Allow the lock type of temp tables to be overwritten now that
the the value is being restored once the table is marked as
free for re-use. This makes the behavior consistent with that
of non-temporary tables and avoids confusion.
Fixed bug when removing a newly inserted record (in case of duplicate key).
The bug caused a crash for rows with several blobs and the first blob was small enough to fit into the head page.
Don't change state_history if nothing changed (speed optimization that also simplifies logic).
Reset state_history if we added/deleted or updated rows without versioning.
Fixed wrong test in trnman_exists_active_transactions() if state is visible or not.
Other bugs fixed:
Fixed wrong argument to (lock->get_status) when we had to wait for TL_WRITE_CONCURRENT_INSERT.
Item_equal::update_used_tables() didn't calculate const_item_cache properly.
Added assert's to detect if join_read_const_table() was called under wrong assumptions..
Fixed that _ma_setup_live_state() is called from thr_lock() instead of handler::external_lock().
This was needed to get versioning information to be setup correctly.
Fixed error in debug binaries during a call to _ma_check_table_is_closed() when another thread was opening/closing a table.
Fixed wrong test when finding right history_state to use.

storage/maria/ha_maria.cc:
Move calling to _ma_setup_live_state() to ma_state.c::_ma_block_get_status()
This was needed as _ma_setup_live_state() needed to know if the table will be used concurrently or not
storage/maria/ma_blockrec.c:
Fixed bug when removing a newly inserted record (in case of duplicate key).
The bug caused a crash for rows with several blobs and the first blob was small enough to fit into the head page.

fails after the first time
Two separate problems :
1. When flattening joins the linked list used for name resolution
(next_name_resolution_table) was not updated.
Fixed by updating the pointers when extending the table list
2. The items created by expanding a * (star) as a column reference
were marked as fixed, but no cached table was assigned to them
(unlike what Item_field::fix_fields does).
Fixed by assigning a cached table (so the re-preparation is done
faster).
Note that the fix for #2 hides the fix for #1 in most cases
(except when a table reference cannot be cached).

``FLUSH TABLES WITH READ LOCK''
Concurrent execution of 1) multitable update with a
NATURAL/USING join and 2) a such query as "FLUSH TABLES
WITH READ LOCK" or "ALTER TABLE" of updating table led
to a server crash.
The mysql_multi_update_prepare() function call is optimized
to lock updating tables only, so it postpones locking to
the last, and if locking fails, it does cleanup of modified
syntax structures and repeats a query analysis. However,
that cleanup procedure was incomplete for NATURAL/USING join
syntax data: 1) some Field_item items pointed into freed
table structures, and 2) the TABLE_LIST::join_columns fields
was not reset.
Major change:
short-living Field *Natural_join_column::table_field has
been replaced with long-living Item*.

Bug #38691: segfault/abort in ``UPDATE ...JOIN'' while
``FLUSH TABLES WITH READ LOCK''
The Item_field constructor has been modified to allocate

an initialization of Item_field items with a pointer to
short-living Field structures is a common practice.
sql/sql_base.cc:
Bug #38691: segfault/abort in ``UPDATE ...JOIN'' while
``FLUSH TABLES WITH READ LOCK''
1) Type adjustment for Natural_join_column::table_field
(Field to Item_field);
2) The setup_natural_join_row_types function has been
updated to take into account new
first_natural_join_processing flag to skip unnecessary
reinitialization of Natural_join_column::join_columns
during table reopening after lock_tables() failure
(like the 'first_execution' flag for PS).
sql/sql_lex.cc:
Bug #38691: segfault/abort in ``UPDATE ...JOIN'' while
``FLUSH TABLES WITH READ LOCK''
Initialization of the new
st_select_lex::first_natural_join_processing flag has

Type adjustment for Natural_join_column::table_field

sql/table.h:
Bug #38691: segfault/abort in ``UPDATE ...JOIN'' while
``FLUSH TABLES WITH READ LOCK''
Type of the Natural_join_column::table_field field has
been changed from Field that points into short-living
TABLE memory to long-living Item_field that can be
linked to (fixed) reopened table.
DBUG_EXECUTE_IF macro. The usage of the former caused breakage in other
trees as it got removed from the dbug library.
sql/sql_base.cc:
Rework code to remove unreliable usage of _db_script_keyword_.
The problem is that when statement-based replication was enabled,
statements such as INSERT INTO .. SELECT FROM .. and CREATE TABLE
.. SELECT FROM need to grab a read lock on the source table that
does not permit concurrent inserts, which would in turn be denied
if the source table is a log table because log tables can't be
locked exclusively.
The solution is to not take such a lock when the source table is
a log table as it is unsafe to replicate log tables under statement
based replication. Furthermore, the read lock that does not permits
concurrent inserts is now only taken if statement-based replication
is enabled and if the source table is not a log table.
include/thr_lock.h:
Introduce yet another lock type that my get upgraded depending
on the binary log format. This is not a optimal solution but
can be easily improved later.

sql/sql_parse.cc:
Remove using_update_log.
sql/sql_update.cc:
Use new function to choose read lock type.
sql/sql_yacc.yy:
The lock type is now decided at open_tables time. This old behavior was
actually misleading as the binary log format can be dynamically switched
and this would not change for statements that have already been parsed
when the binary log format is changed (ie: prepared statements).
The bug was that prepared statements didn't downgrade TL_WRITE_CONCURRENT properly

Indentation fix
columns data types
The "SELECT @lastId, @lastId := Id FROM t" query returns
different result sets depending on the type of the Id column
(INT or BIGINT).
Note: this fix doesn't cover the case when a select query
references an user variable and stored function that
updates a value of that variable, in this case a result
is indeterminate.
The server uses incorrect assumption about a constantness of
an user variable value as a select list item:
The server caches a last query number where that variable
was changed and compares this number with a current query
number. If these numbers are different, the server guesses,
that the variable is not updating in the current query, so
a respective select list item is a constant. However, in some
common cases the server updates cached query number too late.
The server has been modified to memorize user variable
assignments during the parse phase to take them into account
on the next (query preparation) phase independently of the
order of user variable references/assignments in a select
item list.

sql/item_func.h:
1. The Item_func_set_user_var::set_entry() method has been
added to update Item_func_set_user_var::entry.
2. The Item_func_set_user_var::entry_thd field has beend
added to update Item_func_set_user_var::entry only when
needed.
sql/sql_base.cc:
Fix: setup_fiedls() calls Item_func_set_user_var::set_entry()
for all items from the thd->lex->set_var_list before the first
call of ::fix_fields().
sql/sql_lex.cc:
The lex_start function has been modified to reset
the st_lex::set_var_list list.
sql/sql_lex.h:
New st_lex::set_var_list field has been added to
memorize all user variable assignments in the current
select query.
sql/sql_yacc.yy:
The variable_aux rule has been modified to memorize
in-query user variable assignments in the
st_lex::set_var_list list.
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#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.
- Implementing --base64-format=decode-rows, to display
SQL-alike decoded row events without their BINLOG statements.
- Adding --base64-format=decode-rows into tests when
calling mysqlbinlog to avoid non-deterministic results
- Removing resetting of last_table_id in "RESET MASTER",
which appeared to be dangerous.
Implementing -v command line parameter to mysqlbinlog
to decode and print row events.

Tables in the table definition cache are keeping a cache buffer for blob
fields which can consume a lot of memory.
This patch introduces a maximum size threshold for these buffers.
sql/sql_base.cc:
Added function free_field_buffers_larger_than to reclaim memory from blob
field buffers too large to be cached.

When flushing tables, there were a slight chance that the flush was occuring
between processing of two table map events. Since the tables are opened
one by one, it might result in that the tables were not valid and that sub-
sequent locking of tables would cause the slave to crash.
The problem is solved by opening and locking all tables at once using
simple_open_n_lock_tables(). Also, the patch contain a change to open_tables()
so that pre-locking only takes place when the trg_event_map is not zero, which
was not the case before (this caused the lock to be placed in thd->locked_tables
instead of thd->lock since the assumption was that triggers would be called
later and therefore the tables should be pre-locked).

WL#4165 Prepared statements: validation
WL#4166 Prepared statements: automatic re-prepare
Fixes
Bug#27430 Crash in subquery code when in PS and table DDL changed after PREPARE
Bug#27690 Re-execution of prepared statement after table was replaced with a view crashes
Bug#27420 A combination of PS and view operations cause error + assertion on shutdown
The basic idea of the patch is to keep track of table metadata between
prepared statement prepare and execute. If some table used in the statement
has changed, the prepared statement is re-prepared before execution.
See WL#4165 and WL#4166 contents and comments in the code for details
of the implementation.
include/my_global.h:
Remove 'register' keyword to avoid warnings when swapping large structures
that don't fit into a register. Any modern compiler is capable of placing
a variable in a register when that would benefit performance.
mysql-test/r/ps_1general.result:
Update test results: since now we re-prepare automatically,
more correct results are produced in prepare-ddl-execute scenario.
mysql-test/r/query_cache_merge.result:
Ensure that the table definition cache is large enough for
the test to pass in --ps-protocol
mysql-test/r/trigger.result:
Update test results to reflect automatic statement reprepare.
mysql-test/t/disabled.def:
Enable ps_ddl.test, which now passes.
mysql-test/t/ps_1general.test:
Since now we re-execute prepared statements after DDL successfully,
change the test to produce repeatable results. Remove expectancy of
an error in one place where now we automatically reprepare the prepared
statement.
mysql-test/t/query_cache_merge.test:
Ensure the table definition cache is large enough for the test to pass
in --ps-protocol
mysql-test/t/trigger.test:
Sinc
sql/item.cc:
Implement Item_param "copy" functionality, used at re-prepare of
a prepared statement.
We copy the type of the original parameter, and move the assigned value,
if any. Sic, the value is "moved", since it can be quite big --
e.g. in case we deal with a LONG DATA parameter.
It's essential to move the value from the old parameter since
at the time of re-prepare the client packet with the necessary information
may be not available.
sql/item.h:
Declare a new method used for reprepare.
sql/my_decimal.h:
Implement "swap()" functionality of class my_decimal to be
able to easily swap two decimal values.
sql/mysql_priv.h:
Declare enum_metadata_type.
sql/mysqld.cc:
Implement a status variable for the number of reprepared statements.
sql/sql_base.cc:
Implement metadata version validation.
sql/share/errmsg.txt:
Add two new error messages: ER_NEED_REPREPARE and ER_PS_REBIND.
The first error (theoretically) never reaches the user.
It is issued by the metadata validation framework when a metadata version
has changed between prepare and execute. Later on it's intercepted
and the statement is automatically re-prepared. Only if the error
has occurred repeatedly MAX_REPREPARE_ATTEMTS (3) times do we
return it to the user.
The second error is issued when after re-prepare we discover
that the metadata we sent over to the client using the binary
protocol differs drammatically from the new result set metadata
that the reprepared statement produces (e.g. number of result
set columns is different).
sql/sql_class.cc:
Implement metadata version validation framework.
sql/sql_class.h:
Declarations for metadata version validation framework.
sql/sql_parse.cc:
Mark commands for which we must invalidate and reprepare a prepared
statement when metadata has changed.
sql/sql_prepare.cc:
Implement WL#4165 and WL#4166 (limited support of metadata validation
and re-prepare).
sql/table.h:
Implement metadata validation.

The bool data type was redefined to BOOL (4 bytes on windows).
Removed the #define and fixed some of the warnings that were uncovered
by this.
Note that the fix also disables 2 warnings :
4800 : 'type' : forcing value to bool 'true' or 'false' (performance warning)
4805: 'operation' : unsafe mix of type 'type' and type 'type' in operation
These warnings will be handled in a separate bug, as they are performance related or bogus.
Fixed to int the return type of functions that return more than
2 distinct values.

The idea of the fix is to ensure that we always commit the current
statement at the end of dispatch_command(). In order to not issue
redundant disc syncs, an optimization of the two-phase commit
protocol is implemented to bypass the two phase commit if
the transaction is read-only.

Disable the tests, for which this changeset reveals a bug:
the injector thread does not always add 'statement commit' to the
rows injected in circular replication set up.
To be investigated separately.
sql/ha_ndbcluster_binlog.cc:
Add close_thread_tables() to run_query: this ensures
that all tables are closed and there is no pending statement transaction.
sql/handler.cc:
Implement optimisation of read-only transactions.
If a transaction consists only of DML statements that do not change
data, we do not perform a two-phase commit for it
(run one phase commit only).
sql/handler.h:
Implement optimisation of read-only transactions.
If a transaction consists only of DML statements that do not change
data, we do not perform a two-phase commit for it
(run one phase commit only).
sql/log.cc:
Mark the binlog transaction read-write whenever it's started.
We never read from binlog, so it's safe and least intrusive to add
this mark up here.

based on ht->slot.
sql/sql_cursor.cc:
Update to the new layout of thd->transaction.
sql/sql_delete.cc:
Remove wrong and now redundant calls to ha_autocommit_or_rollback.
The transaction is committed in one place, at the end of the statement.
Remove calls to mysql_unlock_tables, since some engines count locks
and commit statement transaction in unlock_tables(), which essentially
equates mysql_unlock_tables to ha_autocommit_or_rollback.
Previously it was necessary to unlock tables soon because we wanted
to avoid sending of 'ok' packet to the client under locked tables.
This is no longer necessary, since OK packet is also sent from one place
at the end of transaction.
sql/sql_do.cc:
Add DO always clears the error, we must rollback the current
statement before this happens. Otherwise the statement will be committed,
and not rolled back in the end.
sql/sql_insert.cc:

Always commit statement transaction before commiting the global one.
Fix an unrelated crash in check_table_access, when called from
information_schema.
sql/sql_partition.cc:
Partitions commit at the end of a DDL operation.
Make sure that send_ok() is done only if the commit has succeeded.
sql/sql_table.cc:
Use ha_autocommit_or_rollback and end_active_trans everywhere.
Add end_trans to mysql_admin_table, so that it leaves no pending
transaction.

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.
mysql-test/r/information_schema.result:
Update test results (Bug#34166).
mysql-test/t/information_schema.test:
Add a test case for Bug#34166.

lex->query_tables_last_own was not NULL.

sql/sql_prepare.cc:

list_open_tables() supplies a table list that is created on stack,
whereas check_table_access() used to assume that the supplied list is a part
of thd->lex.

which is in turn necessary to be able to optimize two-phase
commit of those transactions that do not modify data.
sql/ha_partition.cc:

sql/handler.cc:
Function ha_create_table() is no longer a friend of class handler.

The old code would crash in handler::print_error() in this case.
Implement the newly introduced public ha_* wrappers of the private
virtual handler methods.

The problem is that some DDL statements (ALTER TABLE, CREATE
TRIGGER, FLUSH TABLES, ...) when under LOCK TABLES need to
momentarily drop the lock, reopen the table and grab the write
lock again (using reopen_tables). When grabbing the lock again,
reopen_tables doesn't pass a flag to mysql_lock_tables in
order to ignore the impending global read lock, which causes a
assertion because LOCK_open is being hold. Also dropping the
lock must not signal to any threads that the table has been
relinquished (related to the locking/flushing protocol).
The solution is to correct the way the table is reopenned
and the locks grabbed. When reopening the table and under
LOCK TABLES, the table version should be set to 0 so other
threads have to wait for the table. When grabbing the lock,
any other flush should be ignored because it's theoretically
a atomic operation. The chosen solution also fixes a potential
discrepancy between binlog and GRL (global read lock) because
table placeholders were being ignored, now a FLUSH TABLES WITH
READ LOCK will properly for table with open placeholders.
It's also important to mention that this patch doesn't fix
a potential deadlock if one uses two GRLs under LOCK TABLES
concurrently.

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 patch for Bug 26379 (Combination of FLUSH TABLE and
REPAIR TABLE corrupts a MERGE table) fixed this bug too.
However it revealed a new bug that crashed the server.
Flushing a merge table at the moment when it is between open
and attach of children crashed the server.
The flushing thread wants to abort locks on the flushed table.
It calls ha_myisammrg::lock_count() and ha_myisammrg::store_lock()
on the TABLE object of the other thread.
Changed ha_myisammrg::lock_count() and ha_myisammrg::store_lock()
to accept non-attached children. ha_myisammrg::lock_count() returns
the number of MyISAM tables in the MERGE table so that the memory
allocation done by get_lock_data() is done correctly, even if the
children become attached before ha_myisammrg::store_lock() is
called. ha_myisammrg::store_lock() will not return any lock if the
children are not attached.
This is however a change in the handler interface. lock_count()
can now return a higher number than store_lock() stores locks.
This is more safe than the reverse implementation would be.
get_lock_data() in the SQL layer is adjusted accordingly. It sets
MYSQL_LOCK::lock_count based on the number of locks returned by
the handler::store_lock() calls, not based on the numbers returned
by the handler::lock_count() calls. The latter are only used for
allocation of memory now.
No test case. The test suite cannot reliably run FLUSH between
lock_count() and store_lock() of another thread. The bug report
contains a program that can repeat the problem with some
probability.

This bug is actually two bugs in one, one of which is CREATE TRIGGER under
LOCK TABLES and the other is CREATE TRIGGER under LOCK TABLES simultaneous
to a FLUSH TABLES WITH READ LOCK (global read lock). Both situations could
lead to a server crash or deadlock.
The first problem arises from the fact that when under LOCK TABLES, if the
table is in the set of locked tables, the table is already open and it doesn't
need to be reopened (not a placeholder). Also in this case, if the table is
not write locked, a exclusive lock can't be acquired because of a possible
deadlock with another thread also holding a (read) lock on the table. The
second issue arises from the fact that one should never wait for a global
read lock if it's holding any locked tables, because the global read lock
is waiting for these tables and this leads to a circular wait deadlock.
The solution for the first case is to check if the table is write locked
and upgraded the write lock to a exclusive lock and fail otherwise for non
write locked tables. Grabbin the exclusive lock in this case also means
to ensure that the table is opened only by the calling thread. The second
issue is partly fixed by not waiting for the global read lock if the thread
is holding any locked tables.
The second issue is only partly addressed in this patch because it turned
out to be much wider and also affects other DDL statements. Reported as

The problem is that DROP TABLE and other DDL statements failed to
automatically close handlers associated with tables that were marked
for reopen (FLUSH TABLES).
The current implementation fails to properly discard handlers of
dropped tables (that were marked for reopen) because it searches
on the open handler tables list and using the current alias of the
table being dropped. The problem is that it must not use the open
handler tables list to search because the table might have been
closed (marked for reopen) by a flush tables command and also it
must not use the current table alias at all since multiple different
aliases may be associated with a single table. This is specially
visible when a user has two open handlers (using alias) of a same
table and a flush tables command is issued before the table is
dropped (see test case). Scanning the handler table list is also
useless for dropping handlers associated with temporary tables,
because temporary tables are not kept in the THD::handler_tables
list.
The solution is to simple scan the handlers hash table searching
for, and deleting all handlers with matching table names if the
reopen flag is not passed to the flush function, indicating that
the handlers should be deleted. All matching handlers are deleted
even if the associated the table is not open.

sql/mysql_priv.h:
Rename flush functions to better match the intent of the caller and
update functions prototypes and remove unused flags.
sql/sql_base.cc:
Rename flush functions to better match the intent of the caller.
sql/sql_class.cc:
Rename the flush functions to better match the intent of the caller.
The hash_free function is moved to the cleanup.
sql/sql_handler.cc:
When dropping tables for a final close, scan the handler's hash table since
the table might not be in the handlers open table list because the table was
marked for reopen or because it's a temporary table.
sql/sql_rename.cc:
Drop handlers associated with tables that are being renamed.
sql/sql_table.cc:
Now that temporary tables are properly removed even when opened
by a SQL HANDLER, enable the assert since this branch can't be taken
outside of SF/trigger/prelocked mode.
When the server was out of memory it crashed because of invalid memory access.
This patch adds detection for failed memory allocations and make the server
output a proper error message.
sql/mysqld.cc:
Don't try to push_warning from within push_warning. It will cause a recursion
until the stack is consumed.
If my_net_init fails (for example: because of OOM) the temporary vio object
might have been attached to the thd object already. This will cause a double
free on the vio object when the thd object is deleted later on and the server
will crash.
sql/sp_head.cc:
Added check for out-of-memory on a 'new' operation.
Refactored reset_lex method to return a error state code instead of void.
Initialize the mem-root with init_sql_alloc to get a basic error handler for
memory allocation problems. This alone won't prevent the server from crashing,
NULL pointers have to be accounted for as well.
sql/sp_head.h:
Use the throw() clause in operator new, to indicate to the compiler that
memory allocation can fail and return NULL, so that the compiler should
generate code to check for NULL before invoking C++ constructors, to be
crash safe.

corrupts a MERGE table
Bug 26867 - LOCK TABLES + REPAIR + merge table result in
memory/cpu hogging
Bug 26377 - Deadlock with MERGE and FLUSH TABLE
Bug 25038 - Waiting TRUNCATE
Bug 25700 - merge base tables get corrupted by
optimize/analyze/repair table
Bug 30275 - Merge tables: flush tables or unlock tables
causes server to crash
Bug 19627 - temporary merge table locking
Bug 27660 - Falcon: merge table possible
Bug 30273 - merge tables: Can't lock file (errno: 155)
The problems were:
Bug 26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
1. A thread trying to lock a MERGE table performs busy waiting while
REPAIR TABLE or a similar table administration task is ongoing on
one or more of its MyISAM tables.
2. A thread trying to lock a MERGE table performs busy waiting until all
threads that did REPAIR TABLE or similar table administration tasks
on one or more of its MyISAM tables in LOCK TABLES segments do UNLOCK
TABLES. The difference against problem #1 is that the busy waiting
takes place *after* the administration task. It is terminated by
UNLOCK TABLES only.
3. Two FLUSH TABLES within a LOCK TABLES segment can invalidate the
lock. This does *not* require a MERGE table. The first FLUSH TABLES
can be replaced by any statement that requires other threads to
reopen the table. In 5.0 and 5.1 a single FLUSH TABLES can provoke
the problem.
Bug 26867 - LOCK TABLES + REPAIR + merge table result in
memory/cpu hogging
Trying DML on a MERGE table, which has a child locked and
repaired by another thread, made an infinite loop in the server.
Bug 26377 - Deadlock with MERGE and FLUSH TABLE
Locking a MERGE table and its children in parent-child order
and flushing the child deadlocked the server.
Bug 25038 - Waiting TRUNCATE
Truncating a MERGE child, while the MERGE table was in use,
let the truncate fail instead of waiting for the table to
become free.
Bug 25700 - merge base tables get corrupted by
optimize/analyze/repair table
Repairing a child of an open MERGE table corrupted the child.
It was necessary to FLUSH the child first.
Bug 30275 - Merge tables: flush tables or unlock tables
causes server to crash
Flushing and optimizing locked MERGE children crashed the server.
Bug 19627 - temporary merge table locking
Use of a temporary MERGE table with non-temporary children
could corrupt the children.
Temporary tables are never locked. So we do now prohibit
non-temporary chidlren of a temporary MERGE table.
Bug 27660 - Falcon: merge table possible
It was possible to create a MERGE table with non-MyISAM children.
Bug 30273 - merge tables: Can't lock file (errno: 155)
This was a Windows-only bug. Table administration statements
sometimes failed with "Can't lock file (errno: 155)".
These bugs are fixed by a new implementation of MERGE table open.
When opening a MERGE table in open_tables() we do now add the
child tables to the list of tables to be opened by open_tables()
(the "query_list"). The children are not opened in the handler at
this stage.
After opening the parent, open_tables() opens each child from the
now extended query_list. When the last child is opened, we remove
the children from the query_list again and attach the children to
the parent. This behaves similar to the old open. However it does
not open the MyISAM tables directly, but grabs them from the already
open children.
When closing a MERGE table in close_thread_table() we detach the
children only. Closing of the children is done implicitly because
they are in thd->open_tables.
For more detail see the comment at the top of ha_myisammrg.cc.
Changed from open_ltable() to open_and_lock_tables() in all places
that can be relevant for MERGE tables. The latter can handle tables
added to the list on the fly. When open_ltable() was used in a loop
over a list of tables, the list must be temporarily terminated
after every table for open_and_lock_tables().
table_list->required_type is set to FRMTYPE_TABLE to avoid open of
special tables. Handling of derived tables is suppressed.
These details are handled by the new function
open_n_lock_single_table(), which has nearly the same signature as
open_ltable() and can replace it in most cases.
In reopen_tables() some of the tables open by a thread can be
closed and reopened. When a MERGE child is affected, the parent
must be closed and reopened too. Closing of the parent is forced
before the first child is closed. Reopen happens in the order of
thd->open_tables. MERGE parents do not attach their children
automatically at open. This is done after all tables are reopened.
So all children are open when attaching them.
Special lock handling like mysql_lock_abort() or mysql_lock_remove()
needs to be suppressed for MERGE children or forwarded to the parent.
This depends on the situation. In loops over all open tables one
suppresses child lock handling. When a single table is touched,
forwarding is done.
Behavioral changes:
===================
This patch changes the behavior of temporary MERGE tables.
Temporary MERGE must have temporary children.
The old behavior was wrong. A temporary table is not locked. Hence
even non-temporary children were not locked. See
Bug 19627 - temporary merge table locking.
You cannot change the union list of a non-temporary MERGE table
when LOCK TABLES is in effect. The following does *not* work:
CREATE TABLE m1 ... ENGINE=MRG_MYISAM ...;
LOCK TABLES t1 WRITE, t2 WRITE, m1 WRITE;
ALTER TABLE m1 ... UNION=(t1,t2) ...;
However, you can do this with a temporary MERGE table.
You cannot create a MERGE table with CREATE ... SELECT, neither
as a temporary MERGE table, nor as a non-temporary MERGE table.
CREATE TABLE m1 ... ENGINE=MRG_MYISAM ... SELECT ...;
Gives error message: table is not BASE TABLE.

merge bug 31562 5.0->5.1: changed explain format
The columns in HAVING can reference the GROUP BY and
SELECT columns. There can be "table" prefixes when
referencing these columns. And these "table" prefixes
in HAVING use the table alias if available.
This means that table aliases are subject to the same
storage rules as table names and are dependent on
lower_case_table_names in the same way as the table
names are.
Fixed by :
1. Treating table aliases as table names
and make them lowercase when printing out the SQL
statement for view persistence.
2. Using case insensitive comparison for table
aliases when requested by lower_case_table_names

partitioned table
Trying INSERT DELAYED on a partitioned table, that has not been
used right before, crashes the server. When a table is used for
select or update, it is kept open for some time. This period I
mean with "right before".
Information about partitioning of a table is stored in form of
a string in the .frm file. Parsing of this string requires a
correctly set up lexical analyzer (lex). The partitioning code

to the previously active lex. The delayd insert thread does not
initialize its lex though...
Added initialization for thd->lex before open table in the delayed
thread and at all other places where it is necessary to call
lex_start() if all tables would be partitioned and need to parse
the .frm file.

If a stored function that contains a drop temporary table statement
is invoked by a create temporary table of the same name may cause
a server crash. The problem is that when dropping a table no check
is done to ensure that table is not being used by some outer query
(or outer statement), potentially leaving the outer query with a
reference to a stale (freed) table.
The solution is when dropping a temporary table, always check if
the table is being used by some outer statement as a temporary
table can be dropped inside stored procedures.
The check is performed by looking at the TABLE::query_id value for
temporary tables. To simplify this check and to solve a bug related
to handling of temporary tables in prelocked mode, this patch changes
the way in which this member is used to track the fact that table is
used/unused. Now we ensure that TABLE::query_id is zero for unused
temporary tables (which means that all temporary tables which were
used by a statement should be marked as free for reuse after it's
execution has been completed).

sql/sql_base.cc:
Changed the approach to distinguishing currently unused temporary tables.
Now we ensure that such tables always have TABLE::query_id set to 0 and
use this fact to perform checks during opening and dropping of temporary
tables. This means that we have to call close_thread_tables() even for
statements which use only temporary tables. To make this call cheaper,
we re-factored close_thread_tables() to not take LOCK_open unless there
are open base tables.
sql/sql_handler.cc:

sql/sql_insert.cc:
close_temporary_table is now merged into drop_temporary_table.

SHOW FIELDS FROM a view with no valid definer was possible (since fix
for Bug#26817), but gave NULL as a field-type. This led to mysqldump-ing
of such views being successful, but loading such a dump with the client
failing. Patch allows SHOW FIELDS to give data-type of field in underlying
table.
mysql-test/r/information_schema_db.result:
Fix test results: SHOW FIELDS FROM a view with no valid DEFINER
gives us the field-type of the underlying table now rather than NULL.
sql/sql_base.cc:
In the case of SHOW FIELDS FROM <view>, do not require a valid
DEFINER for determining underlying data-type like we usually do.
This is needed for mysqldump.
The root cause of this defect is that a call to my_error() is using a
'LEX_STRING' parameter instead of a 'char*'
This patch fixes the failing calls to my_error(), as well as similar calls
found during investigation.
This is a compiling bug (see the instrumentation in the bug report), no test cases provided.

The server crashed when a thread was killed while locking the
general_log table at statement begin.
The general_log table is handled like a performance schema table.
The state of open tables is saved and cleared so that this table
seems to be the only open one. Then this table is opened and locked.
After writing, the table is closed and the open table state is
restored. Before restoring, however, it is asserted that there is
no current table open.
After locking the table, mysql_lock_tables() checks if the thread
was killed in between. If so, it unlocks the table and returns an
error. open_ltable() just returns with the error and leaves closing
of the table to close_thread_tables(), which is called at
statement end.
open_performance_schema_table() did not take this into account.
It assumed that a failed open_ltable() would not leave an open
table behind.
Fixed by closing thread tables after open_ltable() and before
restore_backup_open_tables_state() if the thread was killed.
No test case. It requires correctly timed parallel execution.
Since this bug was detected by the test suite, it seems
dispensable to add another test.

This deadlock occurs when a client issues a HANDLER ... OPEN statement
that tries to open a table that has a pending name-lock on it by another
client that also needs a name-lock on some other table which is already
open and associated to a HANDLER instance owned by the first client.
The deadlock happens because the open_table() function will back-off
and wait until the name-lock goes away, causing a circular wait if some
other name-lock is also pending for one of the open HANDLER tables.
Such situation, for example, can be easily repeated by issuing a RENAME
TABLE command in such a way that the existing table is already open
as a HANDLER table by another client and this client tries to open
a HANDLER to the new table name.
The solution is to allow handler tables with older versions (marked for
flush) to be closed before waiting for the name-lock completion. This is
safe because no other name-lock can be issued between the flush and the
check for pending name-locks.
The test case for this bug is going to be committed into 5.1 because it
requires a test feature only avaiable in 5.1 (wait_condition).
sql/sql_base.cc:
Improve comments in the open_table() function, stating the importance
of the handler tables flushing for the back-off process.
sql/sql_handler.cc:
Allows handler tables flushes when opening new tables in order to avoid
potential deadlocks. Add comments explaining the importance of the flush.
When expanding a * in a USING/NATURAL join the check for table access
for both tables in the join was done using the grant information of the
first one.
Fixed by getting the grant information for the current table while
iterating through the columns of the join.

The bug caused memory corruption for some queries with top OR level
in the WHERE condition if they contained equality predicates and
other sargable predicates in disjunctive parts of the condition.
The corruption happened because the upper bound of the memory
allocated for KEY_FIELD and SARGABLE_PARAM internal structures
containing info about potential lookup keys was calculated incorrectly
in some cases. In particular it was calculated incorrectly when the
WHERE condition was an OR formula with disjuncts being AND formulas
including equalities and other sargable predicates.

between perm and temp tables. Review fixes.
The original bug report complains that if we locked a temporary table
with LOCK TABLES statement, we would not leave LOCK TABLES mode
when this temporary table is dropped.
Additionally, the bug was escalated when it was discovered than
when a temporary transactional table that was previously
locked with LOCK TABLES statement was dropped, futher actions with
this table, such as UNLOCK TABLES, would lead to a crash.
The problem originates from incomplete support of transactional temporary
tables. When we added calls to handler::store_lock()/handler::external_lock()
to operations that work with such tables, we only covered the normal
server code flow and did not cover LOCK TABLES mode.
In LOCK TABLES mode, ::external_lock(LOCK) would sometimes be called without
matching ::external_lock(UNLOCK), e.g. when a transactional temporary table
was dropped. Additionally, this table would be left in the list of LOCKed
TABLES.
The patch aims to address this inadequacy. Now, whenever an instance
of 'handler' is destroyed, we assert that it was priorly
external_lock(UNLOCK)-ed. All the places that violate this assert
were fixed.
This patch introduces no changes in behavior -- the discrepancy in
behavior will be fixed when we start calling ::store_lock()/::external_lock()
for all tables, regardless whether they are transactional or not,
temporary or not.

sql/handler.h:

sql/lock.cc:
In mysql_lock_tables only call lock_external() for the list of tables that
we called store_lock() for.
E.g. get_lock_data() does not add non-transactional temporary tables to the
lock list, so lock_external() should not be called for them.
Use handler::ha_external_lock() instead of handler::external_lock().
Add comments for mysql_lock_remove(), parameterize one strange
side effect that it has. At least in one place where mysql_lock_remove
is used, this side effect is not desired (DROP TABLE). The parameter
will be dropped in 5.1, along with the side effect.

Bug#25422 (Hang with log tables)
Bug 17876 (Truncating mysql.slow_log in a SP after using cursor locks the
thread)
Bug 23044 (Warnings on flush of a log table)
Bug 29129 (Resetting general_log while the GLOBAL READ LOCK is set causes
a deadlock)
Prior to this fix, the server would hang when performing concurrent
ALTER TABLE or TRUNCATE TABLE statements against the LOG TABLES,
which are mysql.general_log and mysql.slow_log.
The root cause traces to the following code:
in sql_base.cc, open_table()
if (table->in_use != thd)
{
/* wait_for_condition will unlock LOCK_open for us */
wait_for_condition(thd, &LOCK_open, &COND_refresh);
}
The problem with this code is that the current implementation of the
LOGGER creates 'fake' THD objects, like
- Log_to_csv_event_handler::general_log_thd
- Log_to_csv_event_handler::slow_log_thd
which are not associated to a real thread running in the server,
so that waiting for these non-existing threads to release table locks
cause the dead lock.
In general, the design of Log_to_csv_event_handler does not fit into the
general architecture of the server, so that the concept of general_log_thd
and slow_log_thd has to be abandoned:
- this implementation does not work with table locking
- it will not work with commands like SHOW PROCESSLIST
- having the log tables always opened does not integrate well with DDL
operations / FLUSH TABLES / SET GLOBAL READ_ONLY
With this patch, the fundamental design of the LOGGER has been changed to:
- always open and close a log table when writing a log
- remove totally the usage of fake THD objects
- clarify how locking of log tables is implemented in general.
See WL#3984 for details related to the new locking design.
Additional changes (misc bugs exposed and fixed):
1)
mysqldump which would ignore some tables in dump_all_tables_in_db(),
but forget to ignore the same in dump_all_views_in_db().
2)
mysqldump would also issue an empty "LOCK TABLE" command when all the tables
to lock are to be ignored (numrows == 0), instead of not issuing the query.
3)
Internal errors handlers could intercept errors but not warnings
(see sql_error.cc).
4)
Implementing a nested call to open tables, for the performance schema tables,
exposed an existing bug in remove_table_from_cache(), which would perform:
in_use->some_tables_deleted=1;
against another thread, without any consideration about thread locking.
This call inside remove_table_from_cache() was not required anyway,
since calling mysql_lock_abort() takes care of aborting -- cleanly -- threads
that might hold a lock on a table.
This line (in_use->some_tables_deleted=1) has been removed.

by long running transaction
On Windows opened files can't be deleted. There was a special
upgraded lock mode (TL_WRITE instead of TL_WRITE_ALLOW_READ)
in ALTER TABLE to make sure nobody has the table opened
when deleting the old table in ALTER TABLE. This special mode
was causing ALTER TABLE to hang waiting on a lock inside InnoDB.
This special lock is no longer necessary as the server is
closing the tables it needs to delete in ALTER TABLE.
Fixed by removing the special lock.
Note that this also reverses the fix for bug 17264 that deals with
another consequence of this special lock mode being used.

sql/sql_base.cc:
Bug #29644: don't need a special lock mode for Win32 anymore:
the table is closed before the drop.
The need arose when working on Bug 26141, where it became
necessary to replace TABLE_LIST with its forward declaration in a few
headers, and this involved a lot of s/TABLE_LIST/st_table_list/.
Although other workarounds exist, this patch is in line
with our general strategy of moving away from typedef-ed names.
Sometime in future we might also rename TABLE_LIST to follow the
coding style, but this is a huge change.

HA_HAS_OWN_BINLOGGING table flags set).
mysql-test/r/binlog_multi_engine.result:
Result change.
mysql-test/t/binlog_multi_engine.test:
Errors now generated for some statements due to NDB setting the
HA_HAS_OWN_BINLOGGING flag.
sql/sql_base.cc:
Computing both the intersection and union of all table flags in the
logic to decide logging format.
Calculating if there are more than one engine involved in the statement.
For this case, we only consider engines that hold tables that data is
written to.
Adding logic to generate error if more than one engine is involved in

FLUSH LOGS should ignore SET GLOBAL READ_ONLY.
sql/lock.cc:
Sdditional fix-up for bug #26380: LOCK TABLES + FLUSH LOGS causes deadlock
- ignore SET GLOBAL READ_ONLY if MYSQL_LOCK_IGNORE_GLOBAL_READ_ONLY is set.
sql/mysql_priv.h:
Sdditional fix-up for bug #26380: LOCK TABLES + FLUSH LOGS causes deadlock
- MYSQL_LOCK_IGNORE_GLOBAL_READ_ONLY added.
sql/sql_base.cc:
Sdditional fix-up for bug #26380: LOCK TABLES + FLUSH LOGS causes deadlock
- ignore SET GLOBAL READ_ONLY as well if called form a logger.
The log tables are by nature PERFORMANCE_SCHEMA tables,
which should not be affected by SET GLOBAL READ_ONLY or FLUSH TABLES
WITH READ LOCK.
The implementation of FLUSH TABLES WITH READ LOCK already ignored log tables.
Now with this patch, the implementation of LOCK TABLE also ignore a
global read lock for log tables, which was the missing symmetry.
mysql-test/r/flush.result:
Fix for bug #26380: LOCK TABLES + FLUSH LOGS causes deadlock
- test result.
mysql-test/t/flush.test:
Fix for bug #26380: LOCK TABLES + FLUSH LOGS causes deadlock
- test case.
sql/lock.cc:
Fix for bug #26380: LOCK TABLES + FLUSH LOGS causes deadlock
- logger.is_privileged_thread() used.
sql/log.h:
Fix for bug #26380: LOCK TABLES + FLUSH LOGS causes deadlock
- LOGGER::is_privileged_thread() introduced that returns TRUE if a given thread
is either a general_log or a slow_log or a privileged thread.
sql/sql_base.cc:
Fix for bug #26380: LOCK TABLES + FLUSH LOGS causes deadlock
- pass MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK to the mysql_lock_tables() in case of
call from a logger in order not to honor the GLOBAL READ LOCK
and to avoid possible deadlocks.

replication):
Patch to add binlog format capabilities to the InnoDB storage engine.
The engine will not allow statement format logging when in READ COMMITTED
or READ UNCOMMITTED transaction isolation level.
In addition, an error is generated when trying to use READ COMMITTED
or READ UNCOMMITTED transaction isolation level in STATEMENT binlog
mode.
sql/handler.h:
Adding declaration of already global arrays.
sql/share/errmsg.txt:
Adding error messages for invalid changes of transaction isolation level
and binlog mode switch. Removing messages that are not needed any more
(this cset it pushed together with the cset that introduced these
messages, so it is safe to remove the messages).
sql/sql_base.cc:
Some changes to error reporting code to get more informative messages.
storage/innobase/handler/ha_innodb.cc:
Adding capabilities to storage engine.
Ha_innobase:table_flags() now compute flags on a per-statement basis
and the statement capabilities flag is just set if the transaction
isolation level is below READ COMMITTED.
An informative message is printed in the event that the transaction
isolation level is below READ COMMITTED and the binlog mode is STATEMENT.
storage/innobase/handler/ha_innodb.h:
Accomodating to changes in the server code that switched from ulong
to Table_flags as type for the table flags.

The value of "low-priority-updates" option and the LOW PRIORITY
prefix was taken into account at parse time.
This caused triggers (among others) to ignore this flag (if
supplied for the DML statement).
Moved reading of the LOW_PRIORITY flag at run time.
Fixed an incosistency when handling
SET GLOBAL LOW_PRIORITY_UPDATES : now it is in effect for
delayed INSERTs.
Tested by checking the effect of LOW_PRIORITY flag via a
trigger.

Moving code to check storage engine capabilities to after tables
are locked. Moving code to cache table flags so that table flags
are read from the storage engine at the beginning of the statement
in addition to when the storage engine is opened.
To handle CREATE-SELECT, the decision function is called after the
table is created and it is called with all tables that are in the select
part of the statement as well as the newly created table.
sql/handler.cc:
Changing code to cache table flags on a per-statement basis. The table
flags are now retrieved inside ha_external_lock().
sql/handler.h:
Extending TABLEOP_HOOKS with postlock() member.
sql/mysql_priv.h:
Adding prototype declaration of decide_logging_format() function.
sql/sql_base.cc:
Factoring out code to check capabilities into decide_logging_format().
Moving code to check engine capabilities to after the tables are locked.
Correcting a bug causing row-based to not be set when the engines
were not statement-logging capable.
sql/sql_class.h:
Adding selected tables as select_create::select_tables member variable.
sql/sql_insert.cc:
Introducing logic to handle post-locking hook.
select_create::prepare now uses post-lock hook instead of pre-lock hook.
Deciding on logging format especially for CREATE-SELECT by calling
decide_logging_format() in the post-lock hook.
sql/sql_parse.cc:
Adding selected tables as argument to select_create constructor.
Adding support to allow engines to tell what formats they can handle.
The server will generate an error if it is not possible to log the
statement according to the logging mode in effect.
Adding flags to several storage engines to state what they can handle.
Changes to NDB handler removing code that forces row-based mode and
adding flag saying that NDB can only handle row format.
Adding check that binlog flags are only used for real tables that are
opened for writing.

sql/share/errmsg.txt:
Adding error messages for when row- and/or statement-based logging
formats cannot be used.
sql/sql_base.cc:
Adding business logic in lock_tables() to decide when an error should
be thrown because logging is not possible.
Add logic to switch to row format when that is allowed and needed.

If a stored function or a trigger was killed it had aborted but no error
was thrown. This allows the caller statement to continue without a notice.
This may lead to a wrong data being inserted/updated to/deleted as in such
cases the correct result of a stored function isn't guaranteed. In the case
of triggers it allows the caller statement to ignore kill signal and to
waste time because of re-evaluation of triggers that always will fail
because thd->killed flag is still on.
Now the Item_func_sp::execute() and the sp_head::execute_trigger() functions
check whether a function or a trigger were killed during execution and
throws an appropriate error if so.
Now the fill_record() function stops filling record if an error was reported

sql/mysql_priv.h:
Made functions reopen_table() and close_handle_and_leave_table_as_lock()
available outside of sql_base.cc file.
Changed close_data_tables() in such way that after closing handler
for the table it leaves TABLE object for it in table cache not as
placeholder for ordinary name-lock but as placeholder for an exclusive
name-lock. Renamed this routine to close_data_files_and_morph_locks().
sql/sql_base.cc:
Made functions reopen_table() and close_handle_and_leave_table_as_lock()

Changed close_data_tables() in such way that after closing handler
for the table it leaves TABLE object for it in table cache not as
placeholder for ordinary name-lock but as placeholder for an exclusive
name-lock. Renamed this routine to close_data_files_and_morph_locks().
Also adjusted it so it can work properly not only in LOCK TABLES mode.
sql/sql_table.cc:
Changed the way in which ALTER TABLE implementation handles table
locking and invalidation in the most general case (non-temporary table
and not simple RENAME or ENABLE/DISABLE KEYS or partitioning command)
Now after preparing new version of the table we:
1) Wait until all other threads close old version of table.
2) Close instances of table open by this thread and replace them
with exclusive name-locks.
3) Rename the old table to a temp name, rename the new one to the
old name.
4) If we are under LOCK TABLES and don't do ALTER TABLE ... RENAME
we reopen new version of table.
5) Write statement to the binary log.
6) If we are under LOCK TABLES and do ALTER TABLE ... RENAME we
remove name-locks from list of open tables and table cache.
7) If we are not not under LOCK TABLES we rely on close_thread_tables()
call to remove name-locks from table cache and list of open table.
Such approach:
a) Eliminates possibility for concurrent statement to sneak in and get
access to the new version of the table before ALTER TABLE gets logged
into binary log.
b) Ensures that ALTER TABLE behaves under LOCK TABLES in the same way
on all platforms and for all engines (in 5.0 this was not true)
c) Preserves nice invariant that if table is open in some connection
there is a guarantee that .FRM file for this table exists and is
properly named.

Bug#21483 "Server abort or deadlock on INSERT DELAYED with another
implicit insert"
Also fixes and adds test cases for bugs:
20497 "Trigger with INSERT DELAYED causes Error 1165"
21714 "Wrong NEW.value and server abort on INSERT DELAYED to a
table with a trigger".
Post-review fixes.
Problem:
In MySQL INSERT DELAYED is a way to pipe all inserts into a
given table through a dedicated thread. This is necessary for
simplistic storage engines like MyISAM, which do not have internal
concurrency control or threading and thus can not
achieve efficient INSERT throughput without support from SQL layer.
DELAYED INSERT works as follows:
For every distinct table, which can accept DELAYED inserts and has
pending data to insert, a dedicated thread is created to write data
to disk. All user connection threads that attempt to
delayed-insert into this table interact with the dedicated thread in
producer/consumer fashion: all records to-be inserted are pushed
into a queue of the dedicated thread, which fetches the records and
writes them.
In this design, client connection threads never open or lock
the delayed insert table.
This functionality was introduced in version 3.23 and does not take
into account existence of triggers, views, or pre-locking.
E.g. if INSERT DELAYED is called from a stored function, which,
in turn, is called from another stored function that uses the delayed
table, a deadlock can occur, because delayed locking by-passes
pre-locking. Besides:
* the delayed thread works directly with the subject table through
the storage engine API and does not invoke triggers
* even if it was patched to invoke triggers, if triggers,
in turn, used other tables, the delayed thread would
have to open and lock involved tables (use pre-locking).
* even if it was patched to use pre-locking, without deadlock
detection the delayed thread could easily lock out user
connection threads in case when the same table is used both
in a trigger and on the right side of the insert query:
the delayed thread would not release locks until all inserts
are complete, and user connection can not complete inserts
without having locks on the tables used on the right side of the
query.
Solution:
These considerations suggest two general alternatives for the
future of INSERT DELAYED:
* it is considered a full-fledged alternative to normal INSERT
* it is regarded as an optimisation that is only relevant
for simplistic engines.
Since we missed our chance to provide complete support of new
features when 5.0 was in development, the first alternative
currently renders infeasible.
However, even the second alternative, which is to detect
new features and convert DELAYED insert into a normal insert,
is not easy to implement.
The catch-22 is that we don't know if the subject table has triggers
or is a view before we open it, and we only open it in the
delayed thread. We don't know if the query involves pre-locking
until we have opened all tables, and we always first create
the delayed thread, and only then open the remaining tables.
This patch detects the problematic scenarios and converts
DELAYED INSERT to a normal INSERT using the following approach:
* if the statement is executed under pre-locking (e.g. from
within a stored function or trigger) or the right
side may require pre-locking, we detect the situation
before creating a delayed insert thread and convert the statement
to a conventional INSERT.
* if the subject table is a view or has triggers, we shutdown
the delayed thread and convert the statement to a conventional
INSERT.

INSERT DELAYED and pre-locking:
- if under pre-locking, upgrade the lock type to TL_WRITE
and proceed as a normal write
- if DELAYED table has triggers, also request a lock upgrade.
- make sure errors in the delayed thread are propagated
correctly
