Redesigned the handler close functions so that they are usable
at different places where waiting for closing tables is done.
mysql-test/r/flush_table.result:
bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
Added the test results.
mysql-test/t/flush_table.test:
bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
Activated old test case.
Added new test cases.
sql/mysql_priv.h:
bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
Made mysql_ha_close() more flexible.
Removed mysql_ha_closeall(), which closed only one table despite its name.
Added mysql_ha_close_list(), which closes the complete list or all tables and does not lock.
Removed a duplicate declaration.
sql/sql_base.cc:
bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
Added proper close calls before some wait points to avoid deadlocks
or infinite loops.
sql/sql_handler.cc:
bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
Redesigned the internal function find_table_ptr_by_name().
It can now suppress locking and tells if the requested table
has been flushed by itself.
Extended mysql_ha_close() so that it can now suppres locking
and error reporting. That way it can be used at more places and the
old function mysql_ha_closeall() is now obsolete.
Added a new function mysql_ha_close_list() which closes a whole list
of HANDLER tables or all HANDLER tables, if the list is NULL.
Furthermore is can close all 'old' (marked for flush) HANDLER tables.
sql/sql_table.cc:
bug#3565 - HANDLER and FLUSH TABLE/TABLES deadlock.
Replaced the obsolte mysql_ha_closeall() by the new mysql_ha_close().
