+  There are two containers holding information about open handler tables.
+  The first is 'thd->handler_tables'. It is a linked list of TABLE objects.
+  It is used like 'thd->open_tables' in the table cache. The trick is to
+  exchange these two lists during open and lock of tables. Thus the normal
+  table cache code can be used.
+  The second container is a HASH. It holds objects of the type TABLE_LIST.
+  Despite its name, no lists of tables but only single structs are hashed
+  (the 'next' pointer is always NULL). The reason for theis second container
+  is, that we want handler tables to survive FLUSH TABLE commands. A table
+  affected by FLUSH TABLE must be closed so that other threads are not
+  blocked by handler tables still in use. Since we use the normal table cache
+  functions with 'thd->handler_tables', the closed tables are removed from
+  this list. Hence we need the original open information for the handler
+  table in the case that it is used again. This information is handed over
+  to mysql_ha_open() as a TABLE_LIST. So we store this information in the
+  second container, where it is not affected by FLUSH TABLE. The second
+  container is implemented as a hash for performance reasons. Consequently,
+  we use it not only for re-opening a handler table, but also for the
+  HANDLER ... READ commands. For this purpose, we store a pointer to the
+  TABLE structure (in the first container) in the TBALE_LIST object in the
+  second container. When the table is flushed, the pointer is cleared.

-    If the caller did already lock LOCK_open, it must set 'dont_lock'.
-
-  IMPLEMENTATION
-    find_table_ptr_by_name() closes the table, if a FLUSH TABLE is outstanding.
-    It returns a NULL pointer in this case, but flags the situation in
-    'was_flushed'. In that case the normal ER_UNKNOWN_TABLE error messages
-    is suppressed.
+    will be opened.
+    'reopen' is set when a handler table is to be re-opened. In this case,
+    'tables' is the pointer to the hashed TABLE_LIST object which has been

+    'reopen' is also used to suppress the sending of an 'ok' message or
+    error messages.

   DESCRIPTION
-    Find the table 'db'.'table_name' in the list of HANDLER tables of the
-    thread 'thd'. If the table has been marked by FLUSH TABLE(S), close it,
-    flag this situation in '*was_flushed' and broadcast a COND_refresh
-    condition.
-    An empty database (schema) name matches all database (schema) names.
-    If the caller did already lock LOCK_open, it must set 'dont_lock'.
-
-  IMPLEMENTATION
-    Just in case that the table is twice in 'thd->handler_tables' (!?!),
-    the loop does not break when the table was flushed. If another table
-    by that name was found and not flushed, '*was_flushed' is cleared again,
-    since a pointer to an open HANDLER table is returned.
+    The list of HANDLER tables may be NULL, in which case all HANDLER
+    tables are closed (if MYSQL_HA_FLUSH_ALL) is set.
+    If 'tables' is NULL and MYSQL_HA_FLUSH_ALL is not set,
+    all HANDLER tables marked for flush are closed.
+    Broadcasts a COND_refresh condition, for every table closed.
+    The caller must lock LOCK_open.
+
+  NOTE
+    Since mysql_ha_flush() is called when the base table has to be closed,
+    we compare real table names, not aliases. Hence, database names matter.
 
   RETURN
-    *was_flushed                Table has been closed due to FLUSH TABLE.
-    NULL     A HANDLER Table by that name does not exist (any more).
-    != NULL  Pointer to the TABLE structure.
+    0  ok
