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).
length/dec/charset are still in LEX, because they're also used
for CAST and dynamic columns.
also
1. fix "MDEV-7041 COLLATION(CAST('a' AS CHAR BINARY)) returns a wrong result"
2. allow BINARY modifier in stored function RETURN clause
3. allow "COLLATION without CHARSET" in SP/SF (parameters, RETURN, DECLARE)
4. print correct variable name in error messages for stored routine parameters
Problem: SHOW CREATE FUNCTION and SELECT DTD_IDENTIFIER FROM I_S.ROUTINES
returned wrong values in case of ENUM return data type and UCS2
character set.
Fix: the string to collect returned data type was incorrectly set to
"binary" character set, therefore UCS2 values where returned with
extra '\0' characters.
Setting string character set to creation_ctx->get_client_cs()
in sp_find_routine(), and to system_charset_info in sp_create_routine
fixes the problem.
Adding tests:
- the original test with Latin letters
- an extra test with non-Latin letters
# Bug#24690 Stored functions: RETURNing UTF8 strings
# do not return UTF8_UNICODE_CI collation
#
# Bug#17903: cast to char results in binary
# Regression. The character set was not being properly initialized
# for CAST() with a type like CHAR(2) BINARY, which resulted in
# incorrect results or even a server crash.

- Allow "CHARACTER SET cs COLLATE cl" in
SP parameters, RETURNS, DECLARE
- Minor reorganization for "ASCII" and "UNICODE"
related rules, to make the code more readable,
also to allow these aliases:
* "VARCHAR(10) ASCII BINARY" -> CHARACTER SET latin1 COLLATE latin1_bin
* "VARCHAR(10) BINARY ASCII" -> CHARACTER SET latin1 COLLATE latin1_bin
* "VARCHAR(10) UNICODE BINARY" -> CHARACTER SET ucs2 COLLATE ucs2_bin
* "VARCHAR(10) BINARY UNICODE" -> CHARACTER SET ucs2 COLLATE ucs2_bin
Previously these four aliases returned the error
"This version of MySQL does not yet support return value collation".
Note:
This patch allows "VARCHAR(10) CHARACTER SET cs COLLATE cl"
and the above four aliases.
"VARCHAR(10) COLLATE cl" is still not allowed
i.e. when COLLATE is given without CHARACTER SET.
If we want to support this, we need an architecture decision
which character set to use by default.
The problem happened because those tests were using "cp932" and "ucs2" without checking whether these character sets are available. This fix moves test parts to make character set specific parts be tested only if they are:
- some parts were moved to "ctype_ucs.test" and "ctype_cp932.test"
- some parts were moved to the newly added tests "innodb-ucs2.test", "mysqlbinglog-cp932.test" and "sp-ucs2.test"
