[lazy_send mode] problem with alloc_stmt+prepare_stmt operation
---------------------------------------------------------------
Key: CORE-4988
URL: http://tracker.firebirdsql.org/browse/CORE-4988
Project: Firebird Core
Issue Type: Bug
Components: API / Client Library
Affects Versions: 2.5.4, 2.5.5
Reporter: Kovalenko Dmitry
In lazy_send mode, when the statement prepares the first own SQL, fbclient.dll
sends two packet: op_allocate_statement and op_prepare_statement
If first operation [op_allocate_statement] is failed, fbclient.dll not receives
the answer for second operation [op_prepare_statement].
--------------- [interface.cpp, GDS_DSQL_PREPARE]
// Set up for the response packet.
if (statement->rsr_flags.test(Rsr::LAZY))
{
if (!receive_response(rdb, packet))
return user_status[1]; // <------- WRONG EXIT !!!
statement->rsr_id = packet->p_resp.p_resp_object;
SET_OBJECT(rdb, statement, statement->rsr_id);
statement->rsr_flags.clear(Rsr::LAZY);
}
---------------[/interface.cpp]
At result, fbclient.dll starts to works incorrectly.
