87143063d3 Bug#23713 LOCK TABLES + CREATE TRIGGER + FLUSH TABLES WITH READ LOCK = deadlock
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
Bug#32395

4d6543a6f0 Bug#31397 Inconsistent drop table behavior of handler tables.
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.

  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.

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.

611dbd0bb3 Bug#30882 Dropping a temporary table inside a stored function may cause a server crash
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:
  Properly close temporary tables associated with a handler.
sql/sql_insert.cc:
  close_temporary_table is now merged into drop_temporary_table.
sql/sql_parse.cc:
  Now the condition doesn't cover all cases because close_thread_tables()
  must be called even for statements that use only temporary tables.
sql/sql_table.cc:
  Use drop_temporary_table which perform checks to verify if
  the table is not being used. Error path problem is due to
  a handler tables issue and is going to be addressed in bug
  31397.
sql/table.h:
  Rename previously unused clear_query_id and document the usage of
  query_id and open_by_handler.

6dd04c22a6 Cleanup execute_ddl_log_recovery() to not generate an error if
there is nothing to recover.

Discovered while working on Bug#12713


sql/sql_table.cc:
  Use MYF(0) in my_open() in read_ddl_log_header() called from
  execute_ddl_log_recovery() called during the server start up to not
  generate an error if no ddl log exists. This is not an erroneous situation,
  in fact it's the case in any server statrtup. The error was lost
  anyway, since it was pushed into the stack of the artificial thd.

35ca78a0d4 Bug#30854 (Tables name show as binary in slave err msg on vm-win2003-64-b)
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.

6044965c4f Patch for BUG#30736: Row Size Too Large Error Creating a Table and
Inserting Data.

The problem was that under some circumstances Field class was not
properly initialized before calling create_length_to_internal_length()
function, which led to assert failure.

The fix is to do the proper initialization.

The user-visible problem was that under some circumstances
CREATE TABLE ... SELECT statement crashed the server or led
to wrong error message (wrong results).

aec287fd67 Bug #30825: Problems when putting a non-spatial index on a GIS column
Fixed the usage of spatial data (and Point in specific) with 
 non-spatial indexes.
 Several problems :
   - The length of the Point class was not updated to include the 
     spatial reference system identifier. Fixed by increasing with 4 
     bytes.
   - The storage length of the spatial columns was not accounting for
     the length that is prepended to it. Fixed by treating the 
     spatial data columns as blobs (and thus increasing the storage
     length)
   - When creating the key image for comparison in index read wrong
     key image was created (the one needed for and r-tree search,
     not the one for b-tree/other search). Fixed by treating the
     spatial data columns as blobs (and creating the correct kind of
     image based on the index type).

Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack
  
Once had been set the flag might later got reset inside of a stored routine 
execution stack.
The reason was in that there was no check if a new statement started at time 
of resetting.
The artifact affects most of binlogable DML queries. Notice, that multi-update 
is wrapped up within
  bug@27716 fix, multi-delete bug@29136.
  
Fixed with saving parent's statement flag of whether the statement modified 
non-transactional table, and unioning (merging) the value with that was gained 
in mysql_execute_command.
  
Resettling thd->no_trans_update members into thd->transaction.`member`;
Asserting code;
Effectively the following properties are held.
  
1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table
   reflects the fact if such a table got modified by the substatement.
   That also respects THD::really_abort_on_warnin() requirements.
2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as
   the union of the values of all invoked sub-statements.
   That fixes this bug#27417;

Computing of thd->transaction.all.modified_non_trans_table is refined to base to 
the stmt's value for all the case including insert .. select statement which 
before the patch had an extra issue bug@28960.
Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in
to temp_table select. 
  
The supplied test verifies limitely, mostly asserts. The ultimate testing is defered
for bug@13270, bug@23333.

0936976e8d A fix and a test case for Bug#24918 drop table and lock / inconsistent
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:
  Make handler::external_lock() a protected method. Backport from 5.1 its
  public wrapper handler::ha_external_lock().
  Assert that the handler is not closed if it is still locked.
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.
sql/mysql_priv.h:
  Update declaration of mysql_lock_remove().
sql/opt_range.cc:
  Deploy handler::ha_external_lock() instead of handler::external_lock()
sql/sql_base.cc:
  When closing a temporary table, remove the table from the list of LOCKed

4462578a1c WL#3984 (Revise locking of mysql.general_log and mysql.slow_log)
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.

365bbf9814 Fix for bug #29980: 5.1.20 ate my table
Problem: trying to repair an old (e.g. with "old" varstring fields) corrupted 
table with use_frm option we don't actually repair the table, just altering it
which may couse data loss.

Fix: if use_frm repair option is set, do repair instead of altering even 
if the table needs upgrade.

035b06b4e1 BUG#28838 - duplicate external_lock in mysql_alter_table
Removed duplicate call to handler::external_lock() when
ALTER TABLE that doesn't need to copy a table (quick
ALTER TABLE) was executed.

Also quick ALTER TABLE doesn't hold LOCK_open anymore when
it enables/disables indexes.


sql/sql_table.cc:
  Do not call handler::external_lock() as table is already locked
  by open_ltable().
  
  Also do not hold LOCK_open mutex for alter_table_manage_keys() as
  this function doesn't require LOCK_open (LOCK_open is required by
  wait_while_table_is_used() only).

31ea7d042b A follow up after the patch for Bug#21074 - even though
we now have exclusive name lock on the table name in mysql_rm_table_part2,
we still should keep LOCK_open - some storage engines are not
ready for locking scope change and assume that LOCK_open is kept.
Still, the binary logging and query cache invalidation calls
moved out of LOCK_open scope.
Fixes some of the broken 5.1-runtime tests (tests break on asserts).
