when calling a SP from C API"
The bug was caused by lack of checks for misuse in mysql_real_query.
A stored procedure always returns at least one result, which is the
status of execution of the procedure itself.
This result, or so-called OK packet, is similar to a result
returned by INSERT/UPDATE/CREATE operations: it contains the overall
status of execution, the number of affected rows and the number of
warnings. The client test program attached to the bug did not read this
result and ivnoked the next query. In turn, libmysql had no check for
such scenario and mysql_real_query was simply trying to send that query
without reading the pending response, thus messing up the communication
protocol.
The fix is to return an error from mysql_real_query when it's called
prior to retrieval of all pending results.
client/mysqlbinlog.cc:
net_safe_read -> cli_safe_read
include/mysql.h:
Remove a private function from the public header.
include/mysql_com.h:
Remove a define that is never used.
include/sql_common.h:
Add a declaration for cli_safe_read - a function that reads one packet
from the server.
libmysql/libmysql.c:
net_safe_read -> cli_safe_read
Return CR_COMMANDS_OUT_OF_SYNC on attempt to execute a statement
using a connection which has pending result sets.
sql-common/client.c:
Actual fix for Bug#15752: if the server has pending result sets for
the client, return CR_COMMANDS_OUT_OF_SYNC on attempt to execute
another query. Similarly to the behaviour of mysql_use_result(),
multiple result sets block the connection and must be fetched
before it can be used for another query.
This uncovered an error in the protocol: the server doesn't drop
SERVER_MORE_RESULTS_EXISTS status flag upon an error, so in case of
a multi-query like SELECT 1; SELECT syntax_error; SELECT 2;
the client has no way to know that the server won't ever come to
execution of the third query and won't return any result sets for it.
For now, fix it in cli_safe_read, as a proper fix requires extension
of the client-server protocol.
sql/protocol.cc:
Remove a name that is never used.
sql/slave.cc:
net_safe_read -> cli_safe_read
tests/mysql_client_test.c:
Make 'query' a local variable to avoid name clash.
Add a test case for Bug#15752 "Lost connection to MySQL server when

When using a parameter bind MYSQL_TYPE_DATE in a prepared statement,
the time part of the MYSQL_TIME buffer was written to zero in
mysql_stmt_execute(). The param_store_date() function in libmysql.c

There actually was 3 different problems -
hash_user_connections wasn't cleaned
one strdupped database name wasn't freed
and stmt->mem_root wasn't cleaned as it was
replased with mysql->field_alloc for result
For the last one - i made the library using stmt's
fields to store result if it's the case.
include/mysql.h:
statement pointer added to the advanced_command to be checked in
embedded server
include/sql_common.h:
stmt added to the cli_advanced_command interface
libmysql/libmysql.c:
stmt pointer now sent to advanced_command
libmysqld/embedded_priv.h:
it's enough to send database name to check_embedded_connection
libmysqld/lib_sql.cc:
Now we store result directly in the MYSQL_STMT structure to
avoid extra copying

it's enough to only send database pointer to check_embedded_connection
