Declaring an all space column name in the SELECT FROM DUAL or in a view
leads to misleading warning message:
"Leading spaces are removed from name ' '".

The Item::set_name method has been modified to raise warnings like
"Name ' ' has become ''" in case of the truncation of an all
space identifier to an empty string identifier instead of the
"Leading spaces are removed from name ' '" warning message.


sql/item.cc:
  Fixed bug #27695.

1) Ensure "init_db.sql" and "test_db-sql" really get built.

2) Ensure the "*.def" files with NetWare linker options get distributed to the proper directories.


netware/BUILD/compile-netware-END:
  Ensure the "*.def" files are built for NetWare.
  
  This is a backport of a 5.1 fix which may not be needed in 5.0 but cannot do any harm:
  the general "link_sources" step might fall victim to a cleanup which would be fatal
  just for NetWare, because of problems in the ordering of SUBDIR entries.
netware/Makefile.am:
  1) The scripts "init_db.sql" and "test_db.sql" must be built in the NetWare phase.
  
  2) Use "basename", not sed.

1) We do not provide the "isam" table handler in 5.0 and up (different from "myisam" !),
   so we do not need the ".def" files for the "isam"-specific tools.

2) Use "basename" to get the base name of a file, not a harder-to-read sed expression.

Killing a SELECT query with KILL QUERY or KILL CONNECTION
causes a server crash if the query cache is enabled.

Normal evaluation of a query may be interrupted by the
KILL QUERY/CONNECTION statement, in this case the mysql_execute_command
function returns TRUE, and the thd->killed flag has true value.
In this case the result of the query may
be cached incompletely (omitting call to query_cache_insert inside
the net_real_write function), and next call to query_cache_end_of_result
may lead to server crash.
Thus, the query_cache_end_of_result function has been modified to abort
query cache in the case of killed thread.



sql/sql_cache.cc:
  Fixed bug #30201.
  The  query_cache_end_of_result function has been modified to abort query
  cache in the case of query execution failure. Also this function has been
  modified to remove incomplete query block.

Although the query cache doesn't support retrieval of statements containing
column level access control, it was still possible to cache such statements
thus wasting memory.
  
This patch extends the access control check on the target tables to avoid
caching a statement with column level restrictions. 

Views are excepted and can be cached but only retrieved by super user account.

sql/sql_cache.cc:
  The function check_table_access leaves the artifact
  grant.want_privileges= 1, if a statement refers to tables with column level
  privileges. To avoid the statement from being stored into the query cache,
  it is enough to check this flag and set 'safe_to_cache_query' to zero.
sql/sql_cache.h:
  - Removed 'static' attribute or class methods
  - Added THD parameter to process_and_count_tables

HEAP tables can't index BIT fields. Due to this when grouping by such fields is
needed they are converted to a fields of the LONG type when temporary table
is being created. But a side effect of this is that a wrong type of BIT
fields is returned to a client.

Now the JOIN::prepare and the create_distinct_group functions are create
additional hidden copy of BIT fields to preserve original fields untouched.
New hidden fields are used for grouping instead.

This is a follow up for the patch for Bug#26162 "Trigger DML ignores low_priority_updates setting", where the stored procedure ignores the session setting of low_priority_updates.

For every table open operation with default write (TL_WRITE_DEFAULT) lock_type, downgrade the lock type to the session setting of low_priority_updates.


sql/lock.cc:
  Add late lock_type assertion.
sql/sql_base.cc:
  Possibly downgrade lock type to the the session setting of low_priority_updates and also remove early assertion.

Revert the fix for bug 21587.  That bug will be re-opened, and a new
fix must be created.
