that was already analyzed by Oracle: EXPLAIN can return 3 or 4 in "rows"; using replace_column to work around this.

Applying fix from Oracle (Marko) for Bug #46657 "InnoDB plugin: invalid read in index_merge_innodb test (Valgrind)"

The problem was that creating a DECIMAL column from a decimal
value could lead to a failed assertion as decimal values can
have a higher precision than those attached to a table. The
assert could be triggered by creating a table from a decimal
with a large (> 30) scale. Also, there was a problem in
calculating the number of digits in the integral and fractional
parts if both exceeded the maximum number of digits permitted
by the new decimal type.

The solution is to ensure that truncation procedure is executed
when deducing a DECIMAL column from a decimal value of higher
precision. If the integer part is equal to or bigger than the
maximum precision for the DECIMAL type (65), the integer part
is truncated to fit and the fractional becomes zero. Otherwise,
the fractional part is truncated to fit into the space left
after the integer part is copied.

This patch borrows code and ideas from Martin Hansson's patch.

 - Add conditionals for bundled zlib and innodb plugin.
 - Apply patch from bug#46834 to install the test suite in RPMs.
 - Add plugins to RPMs.  Disable example plugins.

in lock_table_remove_low on INSERT SELECT) to mysql-trunk.

INSERT ... SELECT ...

Problem was that when bulk insert is used on an empty
table/partition, it disables the indexes for better
performance, but in this specific case it also tries
to read from that partition using an index, which is
not possible since it has been disabled.

Solution was to allow index reads on disabled indexes
if there are no records.

Also reverted the patch for bug#38005, since that was a workaround
in the partitioning engine instead of a fix in myisam.

(temporary) TABLE, crash

Problem: if one has an open "HANDLER t1", further "TRUNCATE t1" 
doesn't close the handler and leaves handler table hash in an 
inconsistent state, that may lead to a server crash.

Fix: TRUNCATE should implicitly close all open handlers.

Doc. request: the fact should be described in the manual accordingly.

This is a partial correction to the original fix for bug#37098
   Get rid of "Installed (but unpackaged)" files in the RPM build
which used a wrong variable.

view manipulations
      
The bespoke flag was not properly reset after last call to 
fill_record. Fixed by resetting in caller mysql_update.

If the SQL Thread fails to execute an event due to a temporary error (e.g.
ER_LOCK_DEADLOCK) and the option "--slave_transaction_retries" is set the SQL
Thread should not be aborted and the transaction should be restarted from the
beginning and re-executed.

Unfortunately, a wrong interpretation of the THD::is_fatal_error was preventing
this behavior. In a nutshell, "this variable is set to TRUE if an execution of a
compound statement cannot continue. In particular, it is used to disable access
to the CONTINUE or EXIT handlers of stored routines. So even temporary errors
may have this variable set.

To fix the bug, we have done what follows:

   DBUG_ENTER("has_temporary_error");

-  if (thd->is_fatal_error)
-    DBUG_RETURN(0);
-
   DBUG_EXECUTE_IF("all_errors_are_temporary_errors",
                   if (thd->main_da.is_error())
                   {

view that has Group By
      
Table access rights checking function check_grant() assumed
that no view is opened when it's called.
This is not true with nested views where the inner view
needs materialization. In this case the view is already 
materialized when check_grant() is called for it.
This caused check_grant() to not look for table level
grants on the materialized view table.
Fixed by checking if a view is already materialized and if 
it is check table level grants using the original table name
(not the ones of the materialized temp table).
