(ok'd by CTO to fix it in 4.0). Fix to make mysql-test-run work with all Valgrind versions. mysql-test/mysql-test-run.sh: fixing mysql-test-run.sh so that it works indifferently with Valgrind 1.x, 2.x (versions <= 2.0.0 refuse --tool option; versions >=2.1.2 require it; 2.1.0 accepts it). I hope the shell code is portable enough; anyway Valgrind only runs on Linux... I tested it with 2.0.0, 2.1.0, 2.1.2. mysql-test/r/truncate.result: result update mysql-test/t/truncate.test: testing if TRUNCATE resets autoinc counter for temp tables (BUG#5033); testing difference with DELETE FROM. sql/sql_delete.cc: in mysql_truncate(), always reset the autoinc counter, as manual says (even if it's a temp table, which was BUG#5033).
