- Reduced memory requirements for mysqltest to 1/4.th This also gave a speedup for 5x for some tests.
- Reduced memory usage from safe_mutex. - Fixed problem with failing tests that could not restart mysqld becasue the port was reserved - More DBUG information - Fixed bug where bitmap_set_prefix() wrote over buffer area. - Initialize n_pages_flushed in xtradb which was used uninitialized. client/mysqltest.cc: Reduced memory usage (400K -> 80 for simple test; 400M -> 70M for some other tests) - Smaller dynamic arrays at start - Made 'st_connection' significantly smaller by allocation 'mysql' on demand in mysql_init() and storing require_file in a mem_root. - Fixed that when one does --debug we get information from safemalloc in the trace (Most of changes are changing &connect->mysql to connect->mysql libmysql/libmysql.c: Don't call mysql_thread_end() if my_init() was called outside of mysql_server_init() This is needed to get information from my_end() into the DBUG log mysql-test/README: Fixed wrong comment mysql-test/mysql-test-run.pl: Reserv 20 ports / mysql-test-run thread. (Needed as some tests uses 9 mysqld servers) mysys/hash.c: More DBUG information mysys/my_bitmap.c: Fixed bug where bitmap_set_prefix() wrote over buffer area. mysys/safemalloc.c: More DBUG information mysys/thr_mutex.c: Initialize smaller arrays be default. sql-common/client.c: More DBUG_PRINT storage/xtradb/srv/srv0srv.c: Initialize n_pages_flushed which was used uninitialized.
