5f81fbb323 Fix for BUG#13127.
The problem was in the way table references are pre-filtered when
resolving a qualified field. When resolving qualified table references
we search recursively in the operands of the join. If there is
natural/using join with a merge view, the first call to find_field_in_table_ref
makes a recursive call to itself with the view as the new table reference
to search for the column. However the view has both nested_join and
join_columns != NULL so it skipped the test whether the view name matches
the field qualifier. As a result the field was found in the view since the
view already has a field with the same name. Thus the field was incorrectly
resolved as the view field.


mysql-test/r/select.result:
  Test for BUG#13127.
mysql-test/t/select.test:
  Test for BUG#13127.
sql/sql_base.cc:
  The patch contains two independent changes:
  
  - When searching for qualified fields, include merge views and information schema tables
  used with SHOW (both using TABLE_LIST::field_translation to represent result fields) in
  the test that compares the qualifying table with the name of the table reference being
  searched. This change fixes the bug.
  
  - Do not search the materialized list of columns of a NATURAL/USING join if 'table_list'
  is a stored table or merge view. Instead search directly in the table or view as if it
  is not under a natural join. This is a performance improvement since if 'table_list'
  is a stored table, then the search can utilize the name hash for table names.

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.

738ee00503 Bug#12845 - Stress test: Server crashes on CREATE .. SELECT statement
Solution for 5.0.
Changed calls to open_table(). Requested to ignore
flush at places where the command did already lock tables.
This could happen in CREATE ... SELECT and ALTER TABLE.

No test case. The bug can only be triggered by true concurrency.
The stress test suite provides a test case for this.

b3dc4ea3e3 Fix bug #12993 View column rename broken in subselect
When view column aliased in subselect alias is set on ref which represents
field. When tmp table is created for subselect, it takes name of original field
not ref. Because of this alias on view column in subselect is lost. Which
results in reported error.

Now when alias is set on ref, it's set on ref real item too.

dc92221300 Rename:
- current_arena to stmt_arena: the thread may have more than one
'current' arenas: one for runtime data, and one for the parsed 
tree of a statement. Only one of them is active at any moment.
- set_item_arena -> set_query_arena, because Item_arena was renamed to 
Query_arena a while ago
- set_n_backup_item_arena -> set_n_backup_active_arena;
the active arena is the arena thd->mem_root and thd->free_list
are currently pointing at.
- restore_backup_item_arena -> restore_active_arena (with the same
rationale)
- change_arena_if_needed -> activate_stmt_arena_if_needed; this
method sets thd->stmt_arena active if it's not done yet.

    of qualified columns. The idea is:
    - When a column is qualified, search for the column in all
      tables/views underlying each natural join. In this case
      natural joins are *not* considered leaves.
    - If a column is not qualified, then consider natural joins
      as leaves, thus directly search the result columns of
      natural joins.
  * Simplified 'find_field_in_tables()' - unified two similar
    loops into one.
sql/table.cc:
  - Removed method & members not needed after Monty's patch.
sql/table.h:
  - Removed method & members not needed after Monty's patch.
tests/mysql_client_test.c:
  Put back old tests to test that coalesced columns of natural joins can be qualified.

b1921c85ba Fix for bug #11896 "Partial locking in case of recursive trigger definitions".
If we are in stored function or trigger we should ensure that we won't change
table that is already used by calling statement (this can damage table or
easily cause infinite loops). Particularly this means that recursive triggers
should be disallowed.

    we won't change table that is already used by calling statement
    (this can damage table or easily cause infinite loops).
    So if we are opening table for writing, we should check that it
    is not already open by some calling stamement.

7517d7e112 Implementation of WL#2486 -
"Process NATURAL and USING joins according to SQL:2003".

* Some of the main problems fixed by the patch:
  - in "select *" queries the * expanded correctly according to
    ANSI for arbitrary natural/using joins
  - natural/using joins are correctly transformed into JOIN ... ON
    for any number/nesting of the joins.
  - column references are correctly resolved against natural joins
    of any nesting and combined with arbitrary other joins.

* This patch also contains a fix for name resolution of items
  inside the ON condition of JOIN ... ON - in this case items must
  be resolved only against the JOIN operands. To support such
  'local' name resolution, the patch introduces a stack of
  name resolution contexts used at parse time.

NOTICE:
- This patch is not complete in the sense that
  - there are 2 test cases that still do not pass -
    one in join.test, one in select.test. Both are marked
    with a comment "TODO: WL#2486".
  - it does not include a new test specific for the task

  - extra parameter to find_field_in_table_ref
  - commented old code
sql/sql_base.cc:
  This file contains the core of the implementation of the processing
  of NATURAL/USING joins (WL#2486).
  - added many comments to old code
  - refactored the group of find_field_in_XXX procedures, and added a
    new procedure for natural joins. There is one find_field_in_XXX procedure
    per each type of table reference (stored table, merge view, or natural
    join); one meta-procedure that selects the correct one depeneding on the
    table reference; and one procedure that goes over a list of table
    referenes.
  - NATURAL/USING joins are processed through the procedures:
      mark_common_columns, store_natural_using_join_columns,
      store_top_level_join_columns, setup_natural_join_row_types.
    The entry point to processing NATURAL/USING joins is the
    procedure 'setup_natural_join_row_types'.
  - Replaced the specialized Field_iterator_XXX iterators with one
    generic iterator over the fields of a table reference.
  - Simplified 'insert_fields' and 'setup_conds' due to encapsulation of
    the processing of natural joins in a separate set of procedures.

    for each new JOIN ... ON, and popped afterwards.
  - Added support for NATURAL/USING joins.

    representation of column references for stored tables and for
    views.
  - Added a new list TABLE_LIST::next_name_resolution_table to
    support name resolution with NATURAL/USING joins. Also added
    other members to TABLE_LIST to support NATURAL/USING joins.
  - Added a generic iterator over the fields of table references
    of various types - class Field_iterator_table_ref

Fixed bug #12382.
  INSERT statement effectively changed thd->set_query_id to 0,
  while SELECT statement changed it to 0. As a result
  the insert_fields function that expanded '*' was called
  with different values of thd->set_query_id for the query
  SELECT * FROM view depending on whether it was run after
  an INSERT or after a SELECT statement. This was corrected
  by restoring the old value of thd->set_query_id when
  returning from the function setup_fields where possible
  reset could occur.
  If the value of thd->set_query_id == 0 then the fields
  substituted instead of '*' were not registered as used
  for bitmaps used_keys. This caused selection of an invalid
  execution plan for the query SELECT * from <view>.

39fda60043 Fix for bug #10055 "Using stored function with information_schema causes empty
result set".

To enable full access to contents of I_S tables from stored functions
or statements that use them, we manipulate with thread's open tables
state and ensure that we won't cause deadlock when we open tables by
ignoring flushes and name-locks.
Building of contents of I_S.TABLES no longer requires locking of tables
since we use use handler::info() method with HA_STATUS_AUTO flag instead
of handler::update_auto_increment() for obtaining information about
auto-increment values. But this also means that handlers have to implement
support for HA_STATUS_AUTO flag (particularly InnoDB needs it).


mysql-test/r/alter_table.result:
  Updated test results. This change was caused by the fact that now when
  we build contents of I_S tables (and thus output of SHOW INDEX) we
  don't use instances of tables which may be already opened and locked
  by thread (we always use new instance).
mysql-test/r/information_schema.result:
  Added test which checks how information about current auto-increment value for
  table is reported in INFORMATION_SCHEMA.TABLES view.
mysql-test/r/sp.result:
  Added test for bug #10055 "Using stored function with information_schema causes
  empty result set".
mysql-test/t/information_schema.test:
  Added test which checks how information about current auto-increment value for
  table is reported in INFORMATION_SCHEMA.TABLES view.
mysql-test/t/sp.test:
  Added test for bug #10055 "Using stored function with information_schema causes
  empty result set".
sql/mysql_priv.h:
  close_thread_tables():
    Get rid of 'stopper' argument which is no longer used. Now when we need
    to open and then close some table without touching tables which are already
    opened we use THD::reset_n/restore_backup_open_tables_state() methods.
  open_tables()/open_normal_and_derived_tables():
    Added 'flags' argument to be able open tables even if some has done
    a flush or hold namelock on them.
sql/sp.cc:
  close_proc_table/open_proc_table_for_read/db_find_routine():
    Replaced push_open_tables_state/pop_open_tables_state() methods which
    were saving/restoring current open tables state in/from THD::open_state_list
    with reset_n_backup_open_tables_state/restore_backup_open_tables_state()
    methods which assume that backup storage for this state is allocated on
    stack (or elsewhere) by their caller.
  open_proc_table_for_read():
    Since now we can have several open tables states stacked up we can't rely
    rely on checking whether we have some tables open in previous state.
    Instead we always assume that some tables are open and we need to ignore
    flush while locking mysql.proc. We don't really need 
    MYSQL_LOCK_IGNORE_GLOBAL_READ_LOCK in this case since we open mysql.proc table
    only for reading.
sql/sp.h:
  Added declarations of open_proc_table_for_read()/close_proc_table() to be
  able to use them in sql_show.cc.
sql/sql_base.cc:
  close_thread_tables():
    Get rid of 'stopper' argument which is no longer used. Now when we need
    to open and then close some table without touching tables which are already
    opened we use THD::reset_n/restore_backup_open_tables_state() methods.
  open_tables()/open_normal_and_derived_tables():
    Added 'flags' argument to be able open tables even if some has done
    a flush or hold namelock on them.
sql/sql_class.cc:
  Open_tables_state, THD:
    Replaced push_open_tables_state/pop_open_tables_state() methods which
    were saving/restoring current open tables state in/from THD::open_state_list
    with reset_n_backup_open_tables_state/restore_backup_open_tables_state()
    methods which assume that backup storage for this state is allocated on
    stack (or elsewhere) by their caller.
sql/sql_class.h:
  Open_tables_state, THD:
    Replaced push_open_tables_state/pop_open_tables_state() methods which
    were saving/restoring current open tables state in/from THD::open_state_list
    with reset_n_backup_open_tables_state/restore_backup_open_tables_state()
    methods which assume that backup storage for this state is allocated on
    stack (or elsewhere) by their caller.
sql/sql_handler.cc:
  open_tables()/open_normal_and_derived_tables():
    Added 'flags' argument to be able open tables even if some has done
    a flush or hold namelock on them.
sql/sql_prepare.cc:
  open_tables()/open_normal_and_derived_tables():
    Added 'flags' argument to be able open tables even if some has done
    a flush or hold namelock on them.
sql/sql_show.cc:
  get_all_tables():
    Now we use THD::reset_n_/restore_backup_open_tables_state() for 
    saving/restoring open tables state instead of working with it directly
    (This also allows us to have proper content of I_S system tables in
    statements with stored functions and in stored functions). We also
    ignore possible flushes when opening tables (we may create deadlock
    otherwise). Also we do all needed manipulations with LEX in this function
    and not in get_schema_tables_result() now.
  get_schema_tables_record():
    Let us use handler::info() method with HA_STATUS_AUTO flag for obtaining
    information about table's auto-increment value. This allows to avoid locking
    of tables which is needed when we use handler::update_auto_increment() method.
  fill_schema_proc():
    Now we use open_proc_table_for_read/close_proc_table() for access to
    mysql.proc table (so we won't cause deadlock if we already have some
    tables open and locked, this also allows us to have proper content in
    ROUTINES system table in statements using stored functions/in stored
    functions).
  get_schema_tables_result():
    Moved all manipulations with Open_tables_state and LEX needed for
    safe opening of tables to ST_SCHEMA_TABLE::fill_table functions
    (i.e. get_all_tables() and fill_schema_proc()).
sql/sql_update.cc:
  open_tables()/open_normal_and_derived_tables():
    Added 'flags' argument to be able open tables even if some has done
    a flush or hold namelock on them.
