4b954cc094 A patch for BUG#32148: killing a query may be ineffective.
The problem was that THD::killed was reset after a command was
read from the socket, but before it was actually handled. That lead
to a race: if another KILL statement was issued for this connection
in the middle of reading from the socket and processing a command,
THD::killed state would be cleaned.

The fix is to move this cleanup into net_send_error() function.

A sample test case exists in binlog_killed.test:
  - connection 1: start a new transaction on table t1;
  - connection 2: send query to the server (w/o waiting for the
    result) to update data in table t1 -- this query will be blocked
    since there is unfinished transaction;
  - connection 1: kill query in connection 2 and finish the transaction;
  - connection 2: get result of the previous query -- it should be
    the "query-killed" error.

This test however contains race condition, which can not be fixed
with the current protocol: there is no way to guarantee, that the
server will receive and start processing the query in connection 2
(which is intended to get blocked) before the KILL command (sent in
the connection 1) will arrive. In other words, there is no way to
ensure that the following sequence will not happen:

  - connection 1: start a new transaction on table t1;
  - connection 1: kill query in connection 2 and finish the transaction;
  - connection 2: send query to the server (w/o waiting for the
    result) to update data in table t1 -- this query will be blocked
    since there is unfinished transaction;
  - connection 2: get result of the previous query -- the query will
    succeed.

So, there is no test case for this bug, since it's impossible
to write a reliable test case under the current circumstances.

  Move thd->killed cleanup from dispatch_command() to net_send_error().

1ddb4722f4 Bug#16470 crash on grant if old grant tables
Loading 4.1 into 5.0 or 5.1 failed silently because procs_priv table missing.
This caused the server to crash on any attempt to store new grants because
of uninitialized structures.

This patch breaks up the grant loading function into two phases to allow
for procs_priv table to fail with an warning instead of crashing the server.


mysql-test/r/grant.result:
  Test case
mysql-test/t/grant.test:
  Test case making sure that FLUSH PRIVILEGES doesn't crash the server if
  procs_priv is removed.
sql/sql_acl.cc:
  - Refactored grant_reload into two phases: 1. open and lock tables_priv and 
    columns_priv tables, read the data, close tables. 2. open and lock
    procs_priv, read data, close table. Since the tables are independant of
    each other there will be no race conditions and it will be possible to
    handle situations where the procs_priv table isn't present.
  - Refactored the helper function grant_load into new grant_load (without
    procs_priv table) and grant_load_procs_priv.
sql/sql_parse.cc:
  - Changed comment style to doxygen style.

719e64e4a5 Bug#32528 Global read lock with a low priority write lock causes a server crash
FLUSH TABLES WITH READ LOCK fails to properly detect write locked
tables when running under low priority updates.

The problem is that when trying to aspire a global read lock, the
reload_acl_and_cache() function fails to properly check if the thread
has a low priority write lock, which later my cause a server crash or
deadlock.

The solution is to simple check if the thread has any type of the
possible exclusive write locks.

  to emphasize that it should fail in case of any write lock.

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.

              corrupts a MERGE table
  
  Defined new functions add_merge_table_list(),
  attach_merge_children(), detach_merge_children(), and
  fix_merge_after_open() for the new MERGE table open approach.
  
  Added calls of the new functions to
  close_handle_and_leave_table_as_lock(), close_thread_tables(),
  close_thread_table(), unlink_open_table(), reopen_name_locked_table(),
  reopen_table(), drop_locked_tables(), close_temporary_table(),
  and open_tables() respectively.
  
  Prevented special lock handling of merge children (like
  mysql_lock_remove, mysql_lock_merge or mysql_lock_abort)
  at many places. Some of these calls are forwarded to the
  parent table instead.
  
  Added code to set thd->some_tables_deleted for every thread that has
  a table open that we are flushing.
  Added code for MERGE tables to unlink_open_table().
  Added MERGE children to the list of unusable tables in open_table().
  Added MERGE table handling to reopen_table().
  Added lock handling and closing of a parent before the children
  in close_data_files_and_morph_locks().
  Added code for re-attaching children in reopen_tables().
  Added MYSQL_LOCK_NOTIFY_IF_NEED_REOPEN to the locking flags and
  error reporting after mysql_lock_tables() in reopen_tables().
  Added lock handling and closing of a parent before the children
  in close_old_data_files().
  Added lock handling and detaching in drop_locked_tables().
  Added code for removing the children list from the statement list
  to prepare for a repetition in open_tables().
  Added new function open_n_lock_single_table(), which can be used
  as an replacement for open_ltable() in most situations. Internally
  it calls simple_open_n_lock_tables() so hat it is appropriate for
  MERGE tables.
  Disabled use of open_ltable() for MERGE tables.
  Removed function simple_open_n_lock_tables(). It is now inline
  declared in mysql_priv.h.
  Renamed open_and_lock_tables() to open_and_lock_tables_derived()
  with additional parameter 'derived'. open_and_lock_tables() is now
  inline declared in mysql_priv.h.
  Added a check for end-of-list in two loops in lock_tables().
  Added 'thd' argument to init_tmp_table_share().
sql/sql_insert.cc:

  prepare_for_repair().
  Changed from open_ltable() to open_n_lock_single_table() in
  mysql_alter_table() and mysql_checksum_table().
  Disabled change of child list under LOCK TABLES.
  Initialized table_list->table in mysql_recreate_table().
sql/sql_trigger.cc:
  Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE

  of MERGE tables.
  Changed ha_myisammrg::open() to initialize storage engine structures
  and create a list of child tables only. Child tables are not opened.
  Added ha_myisammrg::attach_children(), which does now the main part
  of MERGE open.
  Added ha_myisammrg::detach_children().
  Added calls to ::attach_children() and ::detach_children() to
  ::extra() on HA_EXTRA_ATTACH_CHILDREN and HA_EXTRA_DETACH_CHILDREN
  respectively.
  Added a check for matching TEMPORARY type for children against
  parent.
  Added a check for table def version.
  Added support for thd->open_options to attach_children().
  Changed child path name generation for temporary tables so that

Better solutions here is to disable that code completely in this case.

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).

  function as no callers are using it.
sql/slave.cc:
  Update close_thread_tables call, no more default values
sql/sp_head.cc:
  Update close_thread_tables call, no more default values
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.

8f0df2efe8 Bug#31850 Test crashes in "embedded" server
The mysql_change_user command fails to properly update the database pointer
when no database is selected, leading to "use after free" errors. The same
happens on the user privilege pointer in the thread security context.

The solution is to properly reset and update the database name. Also update
the user_priv pointer so that it doesn't point to freed memory.


sql/sql_connect.cc:
  After a successful call to check_user() without specifying a new
  database name, the previous database thd->db) is freed but the
  pointer is not updated to NULL.
sql/sql_parse.cc:
  Update the security_ctx->priv_user pointer as it is a alias for
  the user security_ctx->user pointer. Also remove unneeded cast,
  the x_free macro casts the argument.

bfae473053 Remove net_printf_error(). Do not talk to network directly in
check_user()/check_connection()/check_for_max_user_connections().

This is a pre-requisite patch for the fix for Bug#12713 "Error in a stored 
function called from a SELECT doesn't cause ROLLBACK of statem"

Implement review comments.


sql/mysql_priv.h:
  check_for_max_user_connections() is used in one place only, make it static.
sql/mysqld.cc:
  Remove net_printf_error(): a consolidation of error reporting facilities
  is necessary to simplify maintenance of the query cache, the 
  client-server protocol, stored procedure continue handlers. 
  Rewrite the only place where its use is somewhat justified 
  (my_error() can not be used since we need to report an error for the thread 
  that does not exist) with my_snprintf()/net_send_error().
sql/protocol.cc:
  Remove net_printf_error().
sql/protocol.h:
  Remove net_printf_error().
sql/sql_connect.cc:
  Remove net_printf_error(). In check_connection()/check_user()/
  check_for_max_user_connections() do not write directly to the network,
  but use the standard my_error() mechanism to record an error in THD.
  It will be sent to the client by the caller. This was the last place
  in the server that would attempt to send an error directly, mainly left 
  untouched by 5.0 refactoring because it is executed only during 
  thread startup.
sql/sql_parse.cc:
  In the old code, when res was greater than 0, it contained an exact 
  error code, e.g. ER_OUT_OF_RESOURCES or NO SUCH DATABASE, 
  or ER_HANDSHAKE_ERROR. I don't know the reason why this error code was 
  ignored, and instead a generic  ER_UNKNOWN_COM_ERROR was pushed into the
  error stack, but knowing the relaxed attitude towards preserving the error
  codes in the old code, I'm inclinded to think that it was a bug.
  
  After this patch, the most specific error message is already pushed,
  so calling my_message() again is useless.
  
  If res is < 0, the error used to be already sent. This is not done
  by the new code, but will be done later, in the end
  of dispatch_command(). When this is done, clear_error() will be called 
  for us - it is in the first lines of do_command.
  
  To sum up, this change is to remove COM_CHANGE_USER specific error handling
  in favor of the standard one employed for all other COM_* commands.

bf18f6d4b8 Bug#30904 SET PASSWORD statement is non-transactional
The SET PASSWORD statement is non-transactional (no explicit transaction
boundaries) in nature and hence is forbidden inside stored functions and
triggers, but it weren't being effectively forbidden.

The implemented fix is to issue a implicit commit with every SET PASSWORD
statement, effectively prohibiting these statements in stored functions
and triggers.

b9b481ec70 Bug#21557 entries in the general query log truncated at 1000 characters.
The general log write function (general_log_print) uses printf style
arguments which need to be pre-processed, meaning that the all arguments
are copied to a single buffer and the problem is that the buffer size is
constant (1022 characters) but queries can be much larger then this.

The solution is to introduce a new log write function that accepts a
buffer and it's length as arguments. The function is to be used when
a formatted output is not required, which is the case for almost all
query write-to-log calls.

This is a incompatible change with respect to the log format of prepared
statements.

sql/log.cc:

9e1604a46c Fix for BUG#24923: Functions with ENUM issues.
The problem was that the RETURNS column in the mysql.proc was of
CHAR(64). That was not enough for storing long-named datatypes.

The fix is to change CHAR(64) to LONGBLOB, and to throw warnings
at the time a stored routine is created if some data is truncated
during writing into mysql.proc.

f1d7a96b0a Bug#28318 (CREATE FUNCTION (UDF) requires a schema) -- part II
The root cause of the issue was that the CREATE FUNCTION grammar,
for User Defined Functions, was using the sp_name rule.
The sp_name rule is intended for fully qualified stored procedure names,
like either ident.ident, or just ident but with a default database
implicitly selected.

A UDF does not have a fully qualified name, only a name (ident), and should
not use the sp_name grammar fragment during parsing.

The fix is to re-organize the CREATE FUNCTION grammar, to better separate:
- creating UDF (no definer, can have AGGREGATE, simple ident)
- creating Stored Functions (definer, no AGGREGATE, fully qualified name)

With the test case provided, another issue was exposed which is also fixed:
the DROP FUNCTION statement was using sp_name and also failing when no database
is implicitly selected, when droping UDF functions.
The fix is also to change the grammar so that DROP FUNCTION works with
both the ident.ident syntax (to drop a stored function), or just the ident
syntax (to drop either a UDF or a Stored Function, in the current database)

c8b6d10509 Bug #29136 erred multi-delete on trans table does not rollback the statement
similar to bug_27716, but it was stressed on in the synopsis on that there is another
side of the artifact affecting behaviour in transaction.

Fixed with deploying multi_delete::send_error() - otherwise never called - and refining its logic
to perform binlogging job if needed.

The changeset includes the following side effects:
- added tests to check bug_23333's scenarios on the mixture of tables for multi_update;
- fixes bug@30763 with two-liner patch and a test coinciding to one added for bug_23333.

  testing another branch of mult-delete: send_eof() (binloggin there), send_error (early return)
sql/sql_class.h:
  a new flag to designate the fact the statement's error has been handled.
  The flag is checked by ::send_error() methods (multi_update and _delete classes)
sql/sql_delete.cc:
  expanding multi_delete::send_error to 
  1. early return if error_handled == t
  2. binlogging locally if there was a non-trans table modified side effect
sql/sql_parse.cc:
  adding multi_update::send_error which can perform binlogging and rollback job in needed
sql/sql_update.cc:
  issues relating to
   
  1. bug_27716 with zeroing of `updated' to serve as the flag of early return from send_error().
     The flag is changed to be a new member error_handled; also moved outside binlogging branch.
     The reason for this change is that bug_23333 fixes were pushed after the bug_27716's and they
     left this flaw (also no test coverage).
  2. bug_30763 with assertion on trans_safe. I decide to make 2 liner fix for that bug here instead of to remove
     those two assertions. This new bug test case is the same as for multi-update on the mixure of tables.
     The rational for this fix:
     presumption for mutli_update::trans_safe to be set to zero at
     multi_update::multi_update or multi_update::initialize_tables() is incorrect.
  
     trans_safe := false should happen only when a non-transactional table gets modified. 
     Therefore, at initialization the member must be be set to true.
