Additional fix:
 1. Revert the unification of DROP FUNCTION
and DROP PROCEDURE, because DROP FUNCTION can be used to
drop UDFs (that have a non-qualified name and don't require
database name to be present and valid).
 2. Fixed the case sensitivity problem by adding a call to 
check_db_name() (similar to the sp_name production).

      
MATCH() function accepts column list as an argument. It was possible to override
this requirement with aliased non-column select expression. Which results in
server crash.

With this fix aliased non-column select expressions are not accepted by MATCH()
function, returning an error.

String::realloc() did not check whether the existing string data fits in
the newly allocated buffer for cases when reallocating a String object
with external buffer (i.e.alloced == FALSE).  This could lead to memory

Bug#42003 tests missing the disconnect of connections <> default
second slice
Content:
1. wait_until_count_sessions.inc
   - One PB run of a test using this routine failed because
     5 seconds timeout were exceeded. Although I have some doubts
     if the assigned timeout was really too small, I increase the
     value to 10. We waste the additional 5 seconds only if the
     tests fails anyway.
   - Print the content of the PROCESSLIST if the poll routine fails
2. minor improvements of formatting
3. query_cache_notembedded:
   Activate the wait_until_count_sessions.inc routine which was
   unfortunately forgotten in the changeset before.

This involves just the tag, no file changes - they were all present before.

In 37553 we declared longlong results for
class Item_str_timefunc as per comments/docs,
but didn't add a method for that. And the
default just wasn't good enough for some
cases.

Changeset adds dedicated val_int() to class.

mysql-test/r/func_sapdb.result:
  More tests for casts of TIME() / TIMEDIFF() with negative results.
mysql-test/t/func_sapdb.test:
  More tests for casts of TIME() / TIMEDIFF() with negative results.
sql/item_timefunc.h:
  Since we claim to provide longlong results, we should have
  a suitable function to provide them (the default won't do).
  This one matches the val_real() variant.

   - If missing: add "disconnect <session>"
   - If physical disconnect of non "default" sessions is not finished
     at test end: add routine which waits till this happened
+ additional improvements
  - remove superfluous files created by the test
  - replace error numbers by error names
  - remove trailing spaces, replace tabs by spaces
  - unify writing of bugs within comments
  - correct comments
  - minor changes of formatting

  backup

            ORDER BY could cause a server crash

Dependent subqueries like

  SELECT COUNT(*) FROM t1, t2 WHERE t2.b
   IN (SELECT DISTINCT t2.b FROM t2 WHERE t2.b = t1.a)

caused a memory leak proportional to the
number of outer rows.


The make_simple_join() function has been modified to
JOIN class method to store join_tab_reexec and
table_reexec values in the parent join only
(make_simple_join of tmp_join may access these values
via 'this' pointer of the parent JOIN).

NOTE: this patch doesn't include standard test case (this is
"out of memory" bug). See bug #42037 page for test cases.

sql/sql_select.h:
  Bug #42037: Queries containing a subquery with DISTINCT and
              ORDER BY could cause a server crash
  
  1. The make_simple_join() function has been modified to
     JOIN class method.
  
  2. Type of JOIN::table_reexec field has been changed from
     TABLE** to TABLE *table_reexec[1]: this field always was
     NULL or a pointer to one-element array of pointers, so
     a pointer to a pointer has been replaced with one pointer
     and unnecessary memory allocation has been eliminated.

Problem: some queries using NAME_CONST(.. COLLATE ...)
lead to server crash due to failed type cast.

Fix: return the underlying item's type in case of
NAME_CONST(.. COLLATE ...) to avoid wrong casting.

Accessing well defined MERGE table may return an error
stating that the merge table is incorrectly defined. This
happens if MERGE child tables were accessed before and we
failed to open another incorrectly defined MERGE table in
this connection.

myrg_open() internally used my_errno as a variable for determining
failure, and thus could be tricked into a wrong decision by other
uses of my_errno.

With this fix we use function local boolean flag instead of my_errno
to determine failure.

myisammrg/myrg_open.c:
  There are two requirement for accessing/setting my_errno variable,
  which were not followed by myrg_open():
  - it must be checked immediately after a function returned an error. There
    must be no calls to other functions that may change it's value between.
  - my_errno value must be set right before a function is going to return an
    error. There must be no calls to other functions that may change it's
    value between (that's why we have these tricks with save_errno at the
    bottom of myrg_open()).
