When we insert a record into MYISAM table which is almost 'full',
we first write record data in the free space inside a file, and then
check if we have enough space after the end of the file.
So if we don't have the space, table will left corrupted.
Similar error also happens when we updata MYISAM tables.

Fixed by modifying write_dynamic_record and update_dynamic_record functions
to check for free space before writing parts of a record

  Added libmysql_r/client_settings.h libmysqld/ha_blackhole.cc to the ignore list
myisam/mi_dynrec.c:
  Bug #31305 myisam tables crash when they are near capacity.
  
  now we check space left in table in write_dynamic_record
  and update_dynamic_record functions.
  If we don't have enough room for the new (updated) record, return with the
  error.

myisam_sort_buffer_size.

An incorrect length of the sort buffer was used when calculating the
maximum number of keys. When myisam_sort_buffer_size is small enough,
this could result in the number of keys < number of
BUFFPEK structures which in turn led to use of uninitialized BUFFPEKs.

Fixed by correcting the buffer length calculation.


myisam/sort.c:
  Use a correct buffer length when calculating the maximum number of keys.
  Assert that for each BUFFPEK structure there is at least one
  corresponding key. Otherwise we would fail earlier and not reach
  merge_buffers().

As the result of DOUBLE claculations can be bigger
than DBL_MAX constant we use in code, we shouldn't use this constatn
as a biggest possible value.
Particularly the rtree_pick_key function set 'min_area= DBL_MAX' relying
that any rtree_area_increase result will be less so we return valid
key. Though in rtree_area_increase function we calculate the area
of the rectangle, so the result can be 'inf' if the rectangle is
huge enough, which is bigger than DBL_MAX.

Code of the rtree_pick_key modified so we always return a valid key.

DELETE query against memory table with btree index may remove
not all matching rows. This happens only when DELETE uses
index read method to find matching rows. E.g. for queries
like DELETE FROM t1 WHERE a=1.

Fixed by reverting fix for BUG9719 and applying proper solution.


heap/hp_delete.c:
  Reverted fix for BUG9719 as it makes queries like
  DELETE FROM t1 WHERE a=1 to remove not all matching
  rows (assuming this is memory table and there is btree
  key over `a`).
  
  This happens because we calculate info->lastkey_len in
  heap_rkey(). When we enter heap_rnext(), info->lastkey_len
  is 0 (set by hp_rb_delete_key()). We need to preserve
  info->lastkey_len in this situation, otherwise
  tree_search_key() will always return smallest value in
  a tree.
heap/hp_rfirst.c:
  If we're performing index_first on a table that was taken from
  table cache, info->lastkey_len is initialized to previous query.
  Thus we set info->lastkey_len to proper value for subsequent
  heap_rnext() calls.
  This is needed for DELETE queries only, otherwise this variable is
  not used.
  Note that the same workaround may be needed for heap_rlast(), but
  for now heap_rlast() is never used for DELETE queries.
heap/hp_rnext.c:
  An optimization for DELETE queries that use index_first()/index_next().
  Use faster tree_search_edge() instead of tree_search_key().
