- Fix the year in Monty Program Ab copyrights in the new files.
- Fix permissions handling so that SHOW EXPLAIN's handling is the
same as SHOW PROCESSLIST's.
- Add Monty Program Ab copyright in new files
- Change Apc_target::make_apc_call() to accept a C++-style
functor (instead of C-style function + parameter)
- Implement new approach to testing (the DBUG_EXECUTE_IF variant)
- add an 'evalp' mysqltest command that is like 'eval' except that
it prints the original query.
- Fix select_describe() not to change join_tab[i]->type
- More tests
First code
- "Asynchronous procedure call" system
- new THD::check_killed() that serves APC request is called from within most important loops
- EXPLAIN code is now able to generate EXPLAIN output on-the-fly [incomplete]
Parts that are still missing:
- put THD::check_killed() call into every loop where we could spend significant amount of time
- Make sure EXPLAIN code works for group-by queries that replace JOIN::join_tab with make_simple_join()
and other such cases.
- User interface: what error code to use, where to get timeout settings from, etc.
