59eaf292de Fixed compiler and valgrind warnings
Added missing DBUG_xxx_RETURN statements
Fixed some usage of not initialized variables (as found by valgrind)
Ensure that we don't remove locked tables used as name locks from open table cache until unlock_table_names() are called.
This was fixed by having drop_locked_name() returning any table used as a name lock so that we can free it in unlock_table_names()
This will allow Tomas to continue with his work to use namelocks to syncronize things.

Note: valgrind still produces a lot of warnings about using not initialized code and shows memory loss errors when running the ndb tests

  CSV is compiled in by default now
include/my_base.h:
  add new ha_extra flag for the log tables
mysql-test/include/im_check_os.inc:

  check log tables structure
mysql-test/lib/init_db.sql:
  create log tables when running tests.
mysql-test/mysql-test-run.pl:

f577d864cd A fix for Bug#7209 "Client error with "Access Denied" on updates
when high concurrency": remove HASH::current_record and make it
an external search parameter, so that it can not be the cause of a 
race condition under high concurrent load.
The bug was in a race condition in table_hash_search,
when column_priv_hash.current_record was overwritten simultaneously
by multiple threads, causing the search for a suitable grant record
to fail.
No test case as the bug is repeatable only under concurrent load.


include/hash.h:
  - remove current_record from HASH, instead modify hash_first,
  hash_next to accept HASH_SEARCH_STATE as an IN/OUT parameter
mysys/hash.c:
  - remove HASH::current_record
  - change declarations of functions that use HASH in read-only mode
    to accept const HASH * instead of HASH *. 
  - implement hash_search; move the old implementation of hash_search
  to hash_first
mysys/testhash.c:
  - adjust the test case to changed function declarations
sql/lock.cc:
  - adjust to changed declarations of hash_search, hash_next

f6cac54bf6 BUG#5390 - problems with merge tables
Problem #1: INSERT...SELECT, Version for 4.1.
INSERT ... SELECT with the same table on both sides (hidden
below a MERGE table) does now work by buffering the select result.
The duplicate detection works now after open_and_lock_tables() 
on the locks.
I did not find a test case that failed without the change in
sql_update.cc. I made the change anyway as it should in theory
fix a possible MERGE table problem with multi-table update.

f631b361b6 Table definition cache, part 2
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
  object and open a handler to the table object

Other noteworthy changes:
- In TABLE_SHARE the most common strings are now LEX_STRING's
- Better error message when table is not found
- Variable table_cache is now renamed 'table_open_cache'
- New variable 'table_definition_cache' that is the number of table defintions that will be cached
- strxnmov() calls are now fixed to avoid overflows
- strxnmov() will now always add one end \0 to result
- engine objects are now created with a TABLE_SHARE object instead of a TABLE object.
- After creating a field object one must call field->init(table) before using it

- For a busy system this change will give you:
 - Less memory usage for table object
 - Faster opening of tables (if it's has been in use or is in table definition cache)
 - Allow you to cache many table definitions objects
 - Faster drop of table

013b3d8ab3 Bug#14397 - OPTIMIZE TABLE with an open HANDLER causes a crash
Version for 5.0.
It fixes three problems:
1. The cause of the bug was that we did not check the table version for
 the HANDLER ... READ commands. We did not notice when a table was
 replaced by a new one. This can happen during ALTER TABLE, REPAIR
 TABLE, and OPTIMIZE TABLE (there might be more cases). I call the fix
 for this problem "the primary bug fix".
2. mysql_ha_flush() was not always called with a locked LOCK_open.
 Though the function comment clearly said it must.
 I changed the code so that the locking is done when required. I call
 the fix for this problem "the secondary fix".
3. In 5.0 (not in 4.1 or 4.0) DROP TABLE had a possible deadlock flaw in
 concur with FLUSH TABLES WITH READ LOCK. I call the fix for this
 problem "the 5.0 addendum fix".

d5303b8ab8 Fix for bug #12704 "Server crashes during trigger execution".
This bug occurs when some trigger for table used by DML statement is created
or changed while statement was waiting in lock_tables(). In this situation
prelocking set which we have calculated becames invalid which can easily lead
to errors and even in some cases to crashes.

With proposed patch we no longer silently reopen tables in lock_tables(),
instead caller of lock_tables() becomes responsible for reopening tables and
recalculation of prelocking set.


mysql-test/t/trigger.test:
  Added tests for bug #12704 "Server crashes during trigger execution".
  Unfortunately these tests rely on the order in which tables are locked
  by statement so they are non-determenistic and therefore should be disabled.
sql/lock.cc:
  mysql_lock_tables():
    Now instead of always reopening altered or dropped tables by itself
    mysql_lock_tables() can notify upper level and rely on caller doing this.
sql/mysql_priv.h:
  Now mysql_lock_tables() can either reopen deleted or altered tables by itself
  or notify caller about such situation through 'need_reopen' argument and rely
  on it in this.
  Also lock_tables() has new 'need_reopen' out parameter through which it
  notifies caller that some tables were altered or dropped so he needs to reopen
  them (and rebuild prelocking set some triggers may change or simply appear).
sql/sp.cc:
  sp_add_used_routine():
    To be able to restore LEX::sroutines_list to its state right after parsing
    we now adjust  LEX::sroutines_list_own_last/sroutines_list_own_elements when
    we add directly used routine.
  sp_remove_not_own_routines():
    Added procedure for restoring LEX::sroutines/sroutines_list to their state
    right after parsing (by throwing out non-directly used routines).
  sp_cache_routines_and_add_tables_for_view()/sp_update_stmt_used_routines():
    We should use LEX::sroutines_list instead of LEX::sroutines as source of
    routines used by view, since LEX::sroutines is not availiable for view
    on second attempt to open it (see comment in open_tables() about it).
sql/sp.h:
  sp_remove_not_own_routines():
    Added procedure for restoring LEX::sroutines/sroutines_list to their state
    right after parsing (by throwing out non-directly used routines).
sql/sp_head.cc:
  Removed assert which is no longer always true.
sql/sql_base.cc:
  reopen_table():
    When we re-open table and do shallow copy of TABLE object we should adjust
    pointers to it in associated Table_triggers_list object. Removed nil
    operation.
  open_tables():
    Now this function is able to rebuild prelocking set for statement if it is
    needed. It also correctly handles FLUSH TABLES which may occur during its
    execution.
  lock_tables():
    Instead of allowing mysql_lock_tables() to silently reopen altered or dropped
    tables let us notify caller and rely on that it will do reopen itself.
    This solves the problem when trigger suddenly appears or changed during
    mysq_lock_tables().
  close_tables_for_reopen():
    Added routine for properly preparing for reopening of tables and recalculation
    of set of prelocked tables.
sql/sql_handler.cc:
  Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_insert.cc:
  Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_lex.cc:
  LEX:
    Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
    which are used for keeping state in which 'sroutines_list' was right after
    statement parsing (and for restoring of this list to this state).
sql/sql_lex.h:
  LEX:
    Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
    which are used for keeping state in which 'sroutines_list' was right after
    statement parsing (and for restoring of this list to this state).
    Added chop_off_not_own_tables() method to simplify throwing away list
    of implicitly used (prelocked) tables.
sql/sql_prepare.cc:
  Now instead of silently reopening altered or dropped tables in
  lock_tables() we notify caller and rely on that the caller will
  reopen tables.
sql/sql_table.cc:
  Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_trigger.cc:
  Added Table_triggers_list::set_table() method to adjust Table_triggers_list
  to new pointer to TABLE instance.
sql/sql_trigger.h:
  Added Table_triggers_list::set_table() method to adjust Table_triggers_list
  to new pointer to TABLE instance.
sql/sql_update.cc:
  Now instead of silently reopening altered or dropped tables in
  lock_tables() we notify caller and rely on that the caller will
  reopen tables.

de6f5ae5ab A fix and a test case for Bug#10760 and complementary cleanups.
The idea of the patch
is that every cursor gets its own lock id for table level locking.
Thus cursors are protected from updates performed within the same 
connection. Additionally a list of transient (must be closed at
commit) cursors is maintained and all transient cursors are closed
when necessary. Lastly, this patch adds support for deadlock
timeouts to TLL locking when using cursors.
+ post-review fixes.


include/thr_lock.h:
  - add a notion of lock owner to table level locking. When using
    cursors, lock owner can not be identified by a thread id any more, 
    as we must protect cursors from updates issued within the same 
    connection (thread). So, each cursor has its own lock identifier to 
    use with table level locking.
  - extend return values of thr_lock and thr_multi_lock with
    THR_LOCK_TIMEOUT and THR_LOCK_DEADLOCK, since these conditions
    are now possible (see comments to thr_lock.c)
mysys/thr_lock.c:
  Better support for cursors:
  - use THR_LOCK_OWNER * as lock identifier, not pthread_t.
  - check and return an error for a trivial deadlock case, when an
    update statement is issued to a table locked by a cursor which has 
    been previously opened in the same connection.
  - add support for locking timeouts: with use of cursors, trivial 
    deadlocks can occur. For now the only remedy is the lock wait timeout,
    which is initialized from a new global variable 'table_lock_wait_timeout'
    Example of a deadlock (assuming the storage engine does not downgrade 
    locks):
    con1: open cursor for select * from t1;
    con2: open cursor for select * from t2;
    con1: update t2 set id=id*2;  -- blocked
    con2: update t1 set id=id*2;  -- deadlock
    Lock timeouts are active only if a connection is using cursors.
  - the check in the wait_for_lock loop has been changed from
    data->cond != cond to data->cond != 0. data->cond is zeroed
    in every place it's changed. 
  - added comments

sql/handler.cc:
  - drop support for ISAM storage engine, which was removed from 5.0
  - close all "transient" cursors at COMMIT/ROLLBACK. A "transient"
    SQL level cursor is a cursor that uses tables that have a transaction-
    specific state.
sql/handler.h:
  - extend struct handlerton with flags, add handlerton *ht to every
    handler instance.
sql/lock.cc:
  - extend mysql_lock_tables to send error to the client if 
    thr_multi_lock returns a timeout or a deadlock error.
sql/mysqld.cc:
  - add server option --table_lock_wait_timeout (in seconds)
sql/set_var.cc:
  - add new global variable 'table_lock_wait_timeout' to specify
  a wait timeout for table-level locks of MySQL (in seconds). The default
  timeout is 50 seconds. The timeout is active only if the connection
  has open cursors.
sql/sql_class.cc:
  - implement Statement_map::close_transient_cursors
  - safety suggests that we need an assert ensuring 
   llock_info->n_cursors is functioning properly, adjust destruction of
   the Statement_map to allow such assert in THD::~THD
sql/sql_class.h:
  - add support for Cursors registry to Statement map.
sql/sql_prepare.cc:
  - maintain a list of cursors that must be closed at commit/rollback.
sql/sql_select.cc:
  - extend class Cursor to support specific at-COMMIT/ROLLBACK behavior.
  If a cursor uses tables of a storage engine that 
  invalidates all open tables at COMMIT/ROLLBACK, it must be closed
  before COMMIT/ROLLBACK is executed.
sql/sql_select.h:
  - add an own lock_id and commit/rollback status flag to class Cursor
tests/mysql_client_test.c:
  A test case for Bug#10760 and complementary issues: test a simple
  deadlock case too.

11f9e513d7 Implementation of Monty's idea: Now we can open mysql.proc table for lookup
of stored routines definitions even if we already have some tables open and
locked. To avoid deadlocks in this case we have to put certain restrictions
on locking of mysql.proc table.

This allows to use stored routines safely under LOCK TABLES without explicitly
mentioning mysql.proc in the list of locked tables. It also fixes bug #11554
"Server crashes on statement indirectly using non-cached function".


mysql-test/r/sp-error.result:
  Added test which checks that now we can read stored routines definitions

sql/lock.cc:
  get_lock_data():
   To be able to open and lock for reading system tables like 'mysql.proc',
   when we already have some tables opened and locked, and avoid deadlocks
   we have to disallow write-locking of these tables with any other tables.
sql/mysql_priv.h:
  open_table() has new parameter which allows to open table even if some-one
  has done a flush or holding namelock on it.
sql/share/errmsg.txt:
  Added error message saying that one cannot write-lock some of system tables
  with any other tables.
sql/sp.cc:
  open_proc_table_for_read()/close_proc_table():
    Added functions to be able open and close mysql.proc table when we already
    have some tables open and locked.
  open_proc_table_for_update():
    Added function to simplify opening of mysql.proc for updates.
  db_find_routine_aux()/db_find_routine()/db_update_routine()/...
    Moved responsibility for opening mysql.proc table from db_find_routine_aux()
    one level up, since this level knows better which type of table access for
    reading of for update it needs.
  sp_function_exists():
    Removed unused function.
sql/sp.h:
  sp_function_exists():
    Removed unused function.
sql/sql_base.cc:
  open_table():
    Added new parameter which allows to open table even if some-one has done a
    flush or holding namelock on it.
  open_unireg_entry():
    Mark 'mysql.proc' as a system table which has special restrictions on its
    locking, but thanks to them can be open and locked even if we already have
    some open and locked.
sql/sql_class.cc:
  Moved THD members holding information about open and locked tables to separate
  Open_tables_state class to be able to save/restore this state easier.
  Added THD::push_open_tables_state()/pop_open_tables_state() methods for
  saving/restoring this state.
sql/sql_class.h:
  Moved THD members holding information about open and locked tables to separate
  Open_tables_state class to be able to save/restore this state easier.
  Added THD::push_open_tables_state()/pop_open_tables_state() methods for
  saving/restoring this state.
sql/sql_lex.cc:
  Removed LEX::proc_table member which was not really used.
sql/sql_lex.h:
  Removed LEX::proc_table member which was not really used.
sql/sql_table.cc:
  open_table() has new parameter which allows to open table even if some-one
  has done a flush or holding namelock on it.
sql/table.h:
  Added TABLE_SHARE::system_table indicating that this table is system table
  like 'mysql.proc' and we want to be able to open and read-lock it even when
  we already have some tables open and locked (and because of this we have
  to put some restrictions on write locking it).

cf2188ca39 Bug#10224 - ANALYZE TABLE crashing with simultaneous CREATE ... SELECT statement.
1.) Added a new option to mysql_lock_tables() for ignoring FLUSH TABLES.
Used the new option in create_table_from_items().
It is necessary to prevent the SELECT table from being reopend.
It would get new storage assigned for its fields, while the
SELECT part of the command would still use the old (freed) storage.
2.) Protected the CREATE TABLE and CREATE TABLE ... SELECT commands
against a global read lock. This prevents a deadlock in
CREATE TABLE ... SELECT in conjunction with FLUSH TABLES WITH READ LOCK
and avoids the creation of new tables during a global read lock.
3.) Replaced set_protect_against_global_read_lock() and
unset_protect_against_global_read_lock() by
wait_if_global_read_lock() and start_waiting_global_read_lock()
in the INSERT DELAYED handling.

f63c8f53b0 Bug#7823 - FLUSH TABLES WITH READ LOCK + INSERT DELAYED = deadlock
Added protection against global read lock while creating and
initializing a delayed insert handler.
Allowed to ignore a global read lock when locking the table
inside the delayed insert handler.
Added some minor improvements.

  in delayed_get_table().
  Changed the table locking in handle_delayed_insert() so that it
  does not wait for global read lock.
