Sergei Golubchik a62e9a83c0 MDEV-15945 --ps-protocol does not test some queries
Make mysqltest to use --ps-protocol more

use prepared statements for everything that server supports
with the exception of CALL (for now).

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).

=========================

1. The testsuite "funcs_1" is mostly intended for additional (compared
   to the common regression tests stored in mysql-test/t) checks
   of features (VIEWS, INFORMATION_SCHEMA, STORED PROCEDURES,...)
   introduced with MySQL 5.0.

2. There were some extensions of this suite when new information_schema
   views were introduced. But in most cases the tests for these views
   were stored within the regression testsuite (mysql-test/t).

   INFORMATION_SCHEMA views introduced with MySQL 5.1
   ==================================================
   ENGINES       (partially tested here)
   EVENTS        (partially tested here)
   FILES
   GLOBAL_STATUS
   GLOBAL_VARIABLES
   PARTITIONS
   PLUGINS
   PROCESSLIST   (full tested here)
   PROFILING
   REFERENTIAL_CONSTRAINTS
   SESSION_STATUS
   SESSION_VARIABLES

3. Some hints for maintainers of this suite:
   - SHOW TABLES ... LIKE '<pattern>'
     does a case sensitive comparison between the tablename and
     the pattern.
     The names of the tables within the informationschema are in uppercase.
     So please use something like
        SHOW TABLES FOR information_schema LIKE 'TABLES'
     when you intend to get the same non empty result set on OS with and
     without case sensitive filesystems and default configuration.
   - The name of the data dictionary is 'information_schema' (lowercase).
   - Server on OS with filesystem with case sensitive filenames
     (= The files 'abc' and 'Abc' can coexist.)
     + default configuration
     Example of behaviour:
     DROP DATABASE information_schema;
     ERROR 42000: Access denied for user ... to database 'information_schema'
     DROP DATABASE INFORMATION_SCHEMA;
     ERROR 42000: Access denied for user ... to database 'INFORMATION_SCHEMA'
   - Try to unify results by
     --replace_result $engine_type <engine_to_be_tested>
     if we could expect that the results for storage engine variants of a
     test differ only in the engine names.
     This makes future maintenance easier.
   - Avoid the use of include/show_msg*.inc.
     They produce "SQL" noise which annoys during server debugging and can be
     easy replaced by "--echo ...".
