* Cleanup session trackerSergey Vojtovich2019-09-241-2/+2
| | | | | | | | | | | | | - call current_schema::mark_as_changed() directly - call state_change::mark_as_changed() directly - replaced SESSION_TRACKER_CHANGED with dummy tracker - replaced Session_tracker::mark_as_changed() with State_tracker::mark_as_changed() - hide and devirtualize original State_tracker::mark_as_changed(), rename it to set_changed() - all implementations of mark_as_changed() now check is_enabled() for consistency - no argument casts anymore

Fix discovered test failures and bugs. tests: * PROCESSLIST shows Execute state, not Query * SHOW STATUS increments status variables more than in text protocol * multi-statements should be avoided (see tests with a wrong delimiter) * performance_schema events have different names in --ps-protocol * --enable_prepare_warnings mysqltest.cc: * make sure run_query_stmt() doesn't crash if there's no active connection (in wait_until_connected_again.inc) * prepare all statements that server supports protocol.h * Protocol_discard::send_result_set_metadata() should not send anything to the client. sql_acl.cc: * extract the functionality of getting the user for SHOW GRANTS from check_show_access(), so that mysql_test_show_grants() could generate the correct column names in the prepare step sql_class.cc: * result->prepare() can fail, don't ignore its return value * use correct number of decimals for EXPLAIN columns sql_parse.cc: * discard profiling for SHOW PROFILE. In text protocol it's done in prepare_schema_table(), but in --ps it is called on prepare only, so nothing was discarding profiling during execute. * move the permission checking code for SHOW CREATE VIEW to mysqld_show_create_get_fields(), so that it would be called during prepare step too. * only set sel_result when it was created here and needs to be destroyed in the same block. Avoid destroying lex->result. * use the correct number of tables in check_show_access(). Saying "as many as possible" doesn't work when first_not_own_table isn't set yet. sql_prepare.cc: * use correct user name for SHOW GRANTS columns * don't ignore verbose flag for SHOW SLAVE STATUS * support preparing REVOKE ALL and ROLLBACK TO SAVEPOINT * don't ignore errors from thd->prepare_explain_fields() * use select_send result for sending ANALYZE and EXPLAIN, but don't overwrite lex->result, because it might be needed to issue execute-time errors (select_dumpvar - too many rows) sql_show.cc: * check grants for SHOW CREATE VIEW here, not in mysql_execute_command sql_view.cc: * use the correct function to check privileges. Old code was doing check_access() for thd->security_ctx, which is invoker's sctx, not definer's sctx. Hide various view related errors from the invoker. sql_yacc.yy: * initialize lex->select_lex for LOAD, otherwise it'll contain garbage data that happen to fail tests with views in --ps (but not otherwise).

The following statements are extended: CREATE USER user@localhost PASSWORD EXPIRE [option] ALTER USER user@localhost PASSWORD EXPIRE [option] If no option is specified, the password is expired with immediate effect. If option is DEFAULT, global policy applies according to the default_password_lifetime system var (if 0, password never expires, if N, password expires every N days). If option is NEVER, the password never expires and if option is INTERVAL N DAY, the password expires every N days. The feature also supports the disconnect_on_expired_password system var and the --connect-expired-password client option. Closes #1166

This feature produces a trace for any SELECT/UPDATE/DELETE/, which contains information about decisions taken by the optimizer during the optimization phase (choice of table access method, various costs, transformations, etc). This feature would help to tell why some decisions were taken by the optimizer and why some were rejected. Trace is session-local, controlled by the @@optimizer_trace variable. To enable optimizer trace we need to write: set @@optimizer_trace variable= 'enabled=on'; To display the trace one can run: SELECT trace FROM INFORMATION_SCHEMA.OPTIMIZER_TRACE; This task also involves: MDEV-18489: Limit the memory used by the optimizer trace introduces a switch optimizer_trace_max_mem_size which limits the memory used by the optimizer trace. This was implemented by Sergei Petrunia.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fills a serious flaw in the implementation of common table expressions. Before this patch an attempt to prepare a statement from a query with a parameter marker in a CTE that was used more than once in the query ended up with a bogus error message. Similarly if a statement in a stored procedure contained a CTE whose specification used a local variables and this CTE was referred to more than once in the statement then the server failed to execute the stored procedure returning a bogus error message on a non-existing field. The problems appeared due to incorrect handling of parameter markers / local variables in CTEs that were referred more than once. This patch fixes the problems by differentiating between the original occurrences of a parameter marker / local variable used in the specification of a CTE and the corresponding occurrences used in copies of this specification. These copies are substituted instead of non-first references to the CTE. The idea of the fix and even some code were taken from the MySQL implementation of the common table expressions.

This order was induced by the order of SELECTs in all_select_list. In 10.4 the order of SELECTs in all_select_list became different and lack of the DT_INIT flags in some open_normal_and_derived_tables() call became critical as some derived tables were not identified as such.

Additionally, fix_fields() could be called multiple times for SP variables, because they are all fixed at a early stage in append_for_log(). Solution: 1. Adding a few helper methods - fix_fields_if_needed() - fix_fields_if_needed_for_scalar() - fix_fields_if_needed_for_bool() - fix_fields_if_needed_for_order_by() and using it in many cases instead of fix_fields() where the "fixed" status is not definitely known to be "false". 2. Adding DBUG_ASSERT(!fixed) into Item_splocal*::fix_fields() to catch double execution. 3. Adding tests. As a good side effect, the patch removes a lot of duplicate code (~60 lines): if (!item->fixed && item->fix_fields(..) && item->check_cols(1)) return true;
